Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mechanical processing, in particular to a fixture for processing mechanical parts. Background Art
[0002] Mechanical parts, also known as mechanical elements, are the basic components of machinery. They are the inseparable individual parts that make up machinery and machines. Mechanical parts are both a discipline that studies and designs the basic mechanical parts of various equipment, and a general term for parts and components. When processing rectangular parts, they need to be clamped.
[0003] In the prior art, during the processing of mechanical parts, the mechanical parts may be processed into irregular shapes, and some mechanical parts may have stepped surfaces. Therefore, when clamping the mechanical parts with stepped surfaces, the side walls of the stepped surface mechanical parts are generally fixed and clamped directly, or the stepped surfaces are fixed and clamped through different clamping pressure plates.
[0004] However, by directly fixing and clamping the side walls of the stepped surface mechanical parts, the stability of the stepped surface cannot be guaranteed, thereby reducing the stability of the clamping fixation. Pressing and clamping the stepped surface by different clamping pressure plates makes disassembly and installation more troublesome, thereby reducing the practicality and convenience of pressing and clamping fixation. Utility Model Content
[0005] The purpose of the present invention is to provide a fixture for machining mechanical parts to solve the problems raised in the above-mentioned background technology.

[0007] Pressing blocks are provided on both sides of the stepped surface workpiece, one side of the pressing block is fixedly connected to the slide, a rack is fixedly installed on one side of the slide, a gear is meshed on one side of the rack, and a top pressure cylinder is installed on the upper side of the gear.
[0008] Preferably, one side of the side pressure cylinder is fixedly connected to the connecting plate, and two connecting plates are provided and are arranged symmetrically about the center plane of the processing table.
[0009] Preferably, one side of the connecting plate is fixedly connected to the side wall of the processing table, and mounting holes are opened on the surface of the connecting plate and are arranged in a linear array.
[0010] Preferably, the output end of the side pressure cylinder is fixedly connected to the soft block, and one side of the soft block is fixedly connected to the large anti-sliding block.
[0011] Preferably, a small anti-sliding block is fixedly connected to the lower surface of the pressing block, one side of the sliding block is fixedly connected to the sliding block, and one side of the sliding block is slidably connected to the slide rail.
[0012] Preferably, the support shell on one side of the slide rail is fixedly connected, the positioning plate on the lower surface of the support shell is fixedly connected, and positioning holes are provided on the positioning plate and the surface of the processing table.
[0013] Preferably, two racks are provided and are arranged symmetrically about the central plane of the support shell. One side of the top pressure cylinder is fixedly connected to the support shell. The output end of the top pressure cylinder is fixedly connected to the support frame. A limiting shaft is provided in the fixed sleeve inside the support frame, and the gear rotating sleeve is provided on the limiting shaft.
[0014] Compared with the prior art, the beneficial effect of the present invention is as follows: the stepped surface workpiece is placed on the processing table, and the side pressure cylinders on both sides of the processing table extend to drive the soft blocks to squeeze and fix the side walls of the stepped surface workpiece, thereby completing the initial clamping and fixation of the stepped surface workpiece, and then the output end of the top pressure cylinder extends to indirectly drive the gear to move downward, and the gear thereby drives the racks on both sides to move, and the racks move downward under the sliding action of the slide. When one of the pressing blocks abuts against the upper surface of the stepped surface workpiece, the top pressure cylinder continues to extend. At this time, the other pressing block continues to drive the pressing block downward through the slide under the meshing action of the rack and gear on its upper side until the other pressing block abuts against the upper surface of the workpiece, thereby completing the pressing, clamping and fixation of the workpiece, thereby improving the stability of the clamping, while also improving convenience and practicality.
