Description

Technical Field

[0001] This utility model belongs to the field of machining technology, specifically relating to a clamping fixture for machining the deformable plane of mechanical parts. Background Technology

[0002] In the machining of mechanical parts, especially the machining of thin-walled or easily deformable flat parts, traditional clamping fixtures have the following problems: 1. Insufficient clamping stability: Traditional fixtures mostly use rigid clamping methods, which easily leads to uneven force on the workpiece, causing deformation or displacement, affecting machining accuracy. 2. Low adjustment efficiency: The positioning mechanism of existing fixtures is mostly manually adjustable, which is time-consuming and difficult to meet the multi-angle positioning requirements of complex workpieces. 3. Poor adaptability: A single fixture structure is difficult to be compatible with workpieces of different sizes or shapes, requiring frequent fixture changes and increasing production costs. 4. Lack of dynamic compensation: Small displacements caused by vibration or thermal deformation during machining cannot be compensated for in real time, leading to the accumulation of machining errors.

[0003] To address the aforementioned issues, while existing technologies employ pneumatic or hydraulically driven clamping devices, these devices often suffer from drawbacks such as complex structures, high maintenance costs, and limited positioning accuracy.

[0004] This invention proposes a clamping fixture that combines high stability, multi-degree-of-freedom adjustment, and dynamic compensation functions by optimizing the collaborative design of the positioning mechanism and the clamp. Utility Model Content

[0005] In view of the problems mentioned above in the background art, the purpose of this utility model is to provide a clamping fixture for machining the deformable plane of mechanical parts, which can have high stability, multi-degree-of-freedom adjustment and dynamic compensation functions.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0007] A clamping fixture for machining the deformable plane of mechanical parts includes a base, a positioning mechanism, a workpiece, a machining table, a positioning part, a fixture, a support part, and a piston rod. The machining table is fixedly disposed on the top of the base. The positioning mechanism includes multiple sets of first cylinders and second cylinders. The first cylinders are disposed on the machining table and connected to the piston rod. The second cylinders are connected to the fixture. The fixture clamps and fixes the positioning part. One end of the support part is connected to the piston rod, and the other end abuts against the workpiece.

[0008] Furthermore, an elastic buffer is provided between the fixture and the second cylinder. This structural design can be used to absorb processing vibrations.

[0009] Furthermore, the positioning part is a detachable positioning part, used to adapt to workpieces of different shapes.

[0010] Furthermore, the clamp is provided with a manual fine-tuning handle on one side, which is used for manual calibration of the clamping angle.

[0011] Furthermore, the first cylinder is fixed to the base by locking bolts.

[0012] Further specified, the first cylinder and the second cylinder are each provided with three sets, and the first cylinder and the second cylinder are provided with an air circuit system. The air circuit system integrates a pressure sensor, which is used to provide real-time feedback on the clamping status.

[0013] Furthermore, the support portion is a height-adjustable structure, and the support portion is provided with a threaded pair, through which the height of the support portion is adjusted.

[0014] The beneficial effects of this utility model are:

[0015] High-precision positioning: Multi-cylinder coordinated drive enables precise multi-dimensional positioning of the workpiece.

[0016] Dynamic stability: Pneumatic pressure is used to dynamically compensate for processing vibrations, reducing workpiece displacement errors.
