First, the dynamic characteristics of the hydraulic fixture
(A) Strong and stable power output
The hydraulic fixture takes the hydraulic system as the power source and can produce strong and stable clamping force. Compared to traditional manual or pneumatic fixtures, hydraulic systems take advantage of the incompressibility of the liquid to convert mechanical energy into liquid pressure energy through the oil pump, which is then transferred to the executive elements of the fixture. For example, in the processing of large mechanical parts, for some large size, heavy weight and high machining accuracy requirements of the workpiece, it is necessary to have a large enough clamping force to ensure the stability of the workpiece during processing. Hydraulic fixture can easily provide thousands or even tens of thousands of Newtons of clamping force to meet the processing needs of such heavy workpiece, "large mechanical parts processing with hydraulic fixture power" this powerful power output to ensure that the workpiece in high-speed cutting, strong grinding and other processing process will not be due to force displacement, so as to ensure processing accuracy.
(2) Flexible power regulation
A significant advantage of hydraulic systems is the flexibility of their power regulation. The operator can precisely control the clamping force of the hydraulic fixture by adjusting the flow rate of the hydraulic pump and the opening of the pressure control valve. In actual processing, different materials, shapes and sizes of the workpiece on the clamping force requirements are different. For some thin-walled workpieces, too large clamping force may cause the workpiece deformation and affect the machining accuracy; For the workpiece with high hardness and complex structure, a large clamping force is needed to ensure the processing stability. The hydraulic fixture can adjust the power output quickly and accurately according to the specific situation of the workpiece, and achieve the adaptation of different workpieces, which involves the "thin-wall workpiece processing hydraulic fixture power adjustment" this flexible power adjustment ability greatly expands the application range of the hydraulic fixture, so that it can adapt to a variety of machining scenarios.
(3) Fast response speed
In automated production lines, fast fixture action response speed is very important to improve production efficiency. The hydraulic jig performs well in this regard, because the hydraulic oil transfer speed is fast, and the inertia of the actuator is small, the hydraulic jig can achieve the clamping and loosening action in a short time. For example, in the automatic processing line of auto parts, the hydraulic fixture can complete a clamping and loosening cycle in a few seconds, and the high-speed cutting process of the machine tool greatly reduces the processing time of a single workpiece and improves the overall productivity of the production line. "Auto parts automatic production line hydraulic jig response speed" The fast response speed enables the hydraulic jig to work closely with the automatic processing equipment to achieve efficient and continuous production operations.
Second, the clamping characteristics of the hydraulic fixture
(1) High-precision clamping
The hydraulic fixture adopts advanced design and manufacturing technology, which can realize high precision clamping positioning. The manufacturing precision of the clamping element is high, and under the action of the hydraulic system, the clamping force can be applied uniformly, avoiding the workpiece deformation or inaccurate positioning caused by the uneven clamping force. In precision mold processing, the accuracy of the mold directly affects the quality and performance of the product, the hydraulic fixture through accurate clamping positioning, can ensure that the position accuracy of the mold parts in the processing process is controlled within a very small tolerance range, such as ±0.01mm or even higher, to meet the strict requirements of precision mold processing for high-precision clamping. "Precision mold machining hydraulic fixture high-precision clamping" high-precision clamping characteristics make the hydraulic fixture an indispensable and important equipment in the field of precision machining.
(2) The clamping force is evenly distributed
The clamping force of the hydraulic fixture is evenly transmitted to each clamping point through the hydraulic oil, which can realize the all-round and uniform clamping of the workpiece. This uniform clamping force distribution is particularly important for some parts with irregular shape and complex structure. Taking aero engine blade as an example, its shape is complex and its wall is thin. In the processing process, uniform clamping force is needed to ensure that all parts of the blade can be stably supported to avoid deformation due to excessive local force. The hydraulic fixture can design a reasonable clamping scheme according to the shape characteristics of the blade, and apply the clamping force evenly through multiple clamping points to ensure the shape accuracy and surface quality of the blade in the processing process. The uniform distribution of the clamping force of the hydraulic fixture for aero engine blade processing effectively improves the processing accuracy and yield of complex workpieces.
(3) Reliable self-locking function
In the machining process, the self-locking performance of the fixture is one of the key factors to ensure the safety and stability of the processing. The hydraulic fixture is usually equipped with a reliable self-locking device, when the clamping force reaches the set value, the self-locking device can automatically lock, even if the hydraulic system fails or the pressure fluctuations, the fixture can still maintain the clamping state of the workpiece to prevent the workpiece from loosening. In heavy machinery processing, once the workpiece is loosened during processing, it may cause serious safety accidents and cause damage to the machine tool equipment. The self-locking function of the hydraulic fixture provides a double guarantee for the processing process, ensuring the safety and stability of the processing. The reliable self-locking performance of the "heavy machinery processing hydraulic fixture self-locking function" makes the hydraulic fixture widely used in various high-risk and high-precision processing occasions.
In summary, the hydraulic fixture with its powerful and stable power output, flexible power regulation, fast response speed and high-precision clamping, clamping force uniform distribution and reliable self-locking function and other characteristics, in the field of modern machining has shown significant advantages. Whether it is in large-scale machinery manufacturing, precision mold processing, or in high-end manufacturing industries such as automobiles and aerospace, hydraulic fixtures play a vital role, providing strong support for improving processing quality and improving production efficiency.
