Through the power device, the positioning device fixes the position of the mechanical parts, which is convenient for subsequent high-precision machining. When the positioning device for machining mechanical parts is in use, the operation is simple. The machining and positioning of mechanical parts can be realized through manual adjustment. Compared with the existing complex large machinery, the equipment has a simple structure, is convenient to carry, and has a low operation difficulty." When it is in use, through the setting of the power device, the positioning device fixes the position of the mechanical parts. By rotating the rotating block, the transmission block drives the moving block to move in a fixed direction, so that the fixture fixes the mechanical parts, which is convenient for subsequent high-precision machining. However, there is an opening groove on the top surface of the positioning fixture, so that debris will enter the inside of the positioning fixture during the machining of mechanical parts, interfering with the use of the positioning fixture, reducing the practicability of the positioning fixture, and not meeting the use requirements of users.

[0004] Therefore, we provide a positioning fixture for machining mechanical parts to solve the above problems. Summary of the Utility Model

[0005] The present application provides a positioning fixture for machining mechanical parts, which solves the problem that there is an opening groove on the top surface of the positioning fixture, so that debris will enter the inside of the positioning fixture during the machining of mechanical parts, interfering with the use of the positioning fixture, reducing the practicability of the positioning fixture, and not meeting the use requirements of users.

[0006] This application provides a positioning fixture for machining mechanical parts, including a fixture housing and a clamping mechanism. The clamping mechanism is arranged inside the fixture housing;

[0007] The clamping mechanism includes a power component, a sliding component, a clamping component, and a spring component. The power component is arranged inside the fixture housing. The sliding component is arranged outside the power component. The clamping component is arranged outside the sliding component. The spring component is arranged inside the clamping component.

[0008] Preferably, the power component includes a motor and a clamping screw. The motor is fixedly installed on the inner bottom wall of the fixture housing. The output shaft of the motor is fixedly connected to two clamping screws through a coupling.

[0009] Preferably, the sliding component includes a slider and an installation inclined plate. The slider is threadedly installed on the outer surface of the clamping screw. Installation inclined plates are fixedly installed on both the front and rear sides of the slider and penetrate and extend to the outside of the fixture housing at one end.

[0010] Preferably, the clamping component includes a clamping shell, a spring chamber, and an installation chamber. The clamping shell is fitted and installed on the outer surface of the installation inclined plate. Two spring chambers are arranged inside the clamping shell. An installation chamber is arranged between the opposite sides of the two spring chambers.

[0011] Preferably, the spring component includes a cylindrical spring and a plug rod. Cylindrical springs are fixedly installed on the opposite side walls of the inner cavities of the two spring chambers. The other end of the cylindrical spring is fixedly installed with a plug rod that penetrates and extends to the inside of the installation inclined plate at one end.

[0012] Preferably, a disassembly and assembly component is arranged inside the installation chamber. The disassembly and assembly component includes a rotating rod, a synchronous gear, a rack bar, and a spring rod.

[0013] Preferably, the inner bottom wall of the installation chamber is rotatably installed with a rotating rod that penetrates and extends to the outside of the clamping shell at one end. The synchronous gear is fixedly installed on the outer surface of the rotating rod. Two rack bars are slidably installed inside the installation chamber.

[0014] Preferably, the opposite sides of the two rack bars are meshed with the outer surface of the synchronous gear. A spring rod is fixedly installed at one end of the rack bar. The other end of the spring rod is fixedly connected to one end of the plug rod. The outer surface of the spring rod is slidably connected to the inside of the cylindrical spring.

[0015] As can be seen from the above technical solutions, the present application provides a positioning fixture for machining mechanical parts. When in use, the mechanical part is placed on the fixture housing, and the motor drives two clamping screws to rotate. The two clamping screws respectively drive the sliders and the mounting inclined plate to move. The mounting inclined plate drives the clamping shell to position and clamp the mechanical part. When replacing the clamping shell, turn the rotating rod and the synchronous gear by hand. The synchronous gear drives the two rack bars and the spring rod to move towards the opposite side. The spring rod drives the insertion rod to contract and drives the insertion rod to squeeze the cylindrical spring. At this time, the insertion rod no longer fixes the mounting inclined plate and the clamping shell, and then the clamping shell can be disassembled and replaced. Similarly, after installing a new clamping shell, the cylindrical spring drives the insertion rod to fix the mounting inclined plate and the clamping shell, thus completing the machining positioning of the mechanical part.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] 1. Through the setting of the disassembly and assembly component, the user can quickly disassemble and replace the clamping shell, which is convenient for realizing the rapid positioning machining of various mechanical parts and facilitates the use of the user;

[0018] 2. Through the setting of the clamping mechanism, the power component drives the clamping component to perform machining positioning on the mechanical part through the sliding component, and the spring component fixes the sliding component and the clamping component. The sliding component can prevent debris from entering the positioning fixture during machining, improving the practicability of the positioning fixture.

[0019] In summary, the present application not only prevents debris from entering the positioning fixture during machining of mechanical parts, but also can quickly disassemble and replace the clamping shell, facilitating the rapid positioning machining of various mechanical parts.

[0032] In this utility model, the spring assembly 24 includes a cylindrical spring 241 and an insertion rod 242. Cylindrical springs 241 are fixedly installed on the opposite side walls of the inner cavities of the two spring chambers 232, and the other end of the cylindrical spring 241 is fixedly installed with an insertion rod 242 that penetrates and extends to the inside of the mounting inclined plate 222.

[0033] In some embodiments, a disassembly and assembly component 3 is arranged inside the installation bin 233. The disassembly and assembly component 3 includes a rotating rod 31, a synchronous gear 32, a rack bar 33, and a spring rod 34.
