A Mechanical Clamping Mechanism That Can Accurately Adjust Clamping Angle

Abstract

The invention discloses a mechanical clamping mechanism capable of precisely adjusting the clamping inclination angle, which includes a positioning mechanism, a motor slot, a supporting mechanism, a dial, an insertion slot and a limit card seat, and the side end surface of the support mechanism passes through the insertion slot The symmetrical rotation snaps into the limited card seat. The present invention can drive two sets of connecting worms to rotate through the fixed motor when adjusting the angle of the clamping workpiece. When the connecting worms rotate, since the connecting worms and the connecting worm gears are meshed, the positioning mechanism can be driven to turn over at the top of the supporting mechanism. , so as to accurately adjust the angle of the workpiece flipping and clamping, and the adjustment method of thread engagement can effectively improve the accuracy and stability of the subsequent adjustment of the clamping angle. The perimeter is programmed, which further improves the accuracy of angle adjustment when clamping the workpiece, reduces the error of manual adjustment, and improves efficiency.

Description

Technical field [0001] The present invention relates to the technical field of mechanical processing equipment, and in particular, a mechanical clamping mechanism that can accurately adjust clamping angles. Background technique [0002] With the development of science and technology, the mechanical processing industry has continuously improved, and more and more mechanical workpieces appear. At the same time, the structural complex curved workpiece is more complicated in the mechanical field, and its operation is more Low, especially some high-performance complex surface aviation critical parts, most of the existing patents are operated by a large-scale non-stage non-stage adjustment fixture such as a flat partial inclination, but this clamp is insufficient. It is also limited to the adjustment angle of the reference surface of the workpiece processing, which reduces the adaptability of the workpiece for processing, [0003] As the patent number: CN201910495787.6 disclosed, a lar...

Problems solved by technology

[0002] With the development of science and technology, the mechanical processing industry continues to progress, and more and more mechanical workpieces emerge as the times require. At the same time, in the mechanical field, it is more complicated to remove materials from curved workpieces with complex structures, and the success rate of the operation is relatively low. Low, especially for some key aviation parts with high performance and complex surfaces, most of the existing patents are operated by a fixture such as a large-scale stepless adjustment fixture for the inclination of flat parts, but this kind of fixture has deficiencies in its operation accuracy. And its adjustment angle to the reference plane of the workpiece processing is limited, which reduces the adaptability of the subsequent processing and clamping of the workpiece.

[0003] For example, the patent number is: CN201910495787.6 discloses a large-range stepless adjustment fixture for parts inclination for laser processing. The fixture can realize the positioning of flat parts through a positioning and clamping unit composed of a clamping device and a positioning block. and clamping; by adjusting the inclination adjustment unit composed of lead screw, support plate, gear, sliding block and lead screw sleeve, etc. and the lead screw fixing unit composed of fastening block, handle and handle sleeve, although the invention can The angle of the fixture clamping the workpiece is adjusted by the handle, screw, support plate, gear and other components, but its operation is performed by manpower, which is prone to errors and reduces the accuracy of the adjustment. At the same time, it adjusts the benchmark of the workpiece The surface angle is also limited, which reduces its overall adaptability, so there is an urgent need for a mechanical clamping mechanism that can accurately adjust the clamping angle to solve the above problems
