Description

Technical Field

[0001] This utility model relates to the field of compressor manufacturing technology, specifically a tooling fixture for processing compressor housings. Background Technology

[0002] The compressor's rear cover is made of metal. When assembling the rear cover with the compressor housing, it needs to be processed. Before processing, the rear cover needs to be clamped and limited by a processing fixture.

[0003] According to a publicly disclosed tooling for processing the rear cover of an automotive air conditioning compressor (Announcement No.: CN 119550120A), the aforementioned application restricts the movement of the multi-head by means of the groove, thereby restricting the movement of the cylinder so that the cylinder is stably mounted on the tooling table. The position and angle of the cylinder are adjusted in this way.

[0004] However, in actual use, the tooling for machining the rear cover of the automotive air conditioning compressor needs to be fixed according to the surface shape of the air conditioning compressor housing. Without corresponding guiding components, placing the compressor housing on the surface of the mounting base can easily lead to inaccurate movement of the housing, resulting in unstable clamping and affecting the machining effect. In view of this, we propose a tooling fixture for machining the compressor housing. Utility Model Content

[0005] The purpose of this utility model is to provide a tooling fixture for processing compressor housings, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tooling fixture for processing compressor housings, comprising a mounting platform, a bracket fixedly mounted on the upper surface of the mounting platform, an electric push rod fixedly mounted on the upper surface of the bracket, a clamping plate fixedly mounted on the movable end of the electric push rod, a limiting mechanism provided on the upper surface of the mounting platform, and a promoting mechanism fixedly mounted on the upper surface of the mounting platform, the limiting mechanism comprising:

[0007] A vertical plate is fixedly installed on the upper surface of the mounting platform. A horizontal plate is fixedly installed on the side wall of the vertical plate. A roller is rotatably installed on the side wall of the vertical plate. Mounting holes are provided on the side wall of the vertical plate.

[0008] A reset spring is fixedly installed on the inner wall of the mounting hole. An auxiliary block is fixedly installed on the end of the reset spring away from the inner wall of the mounting hole. A rotating hole is opened on the side wall of the auxiliary block, and a roller is rotatably connected to the inner wall of the rotating hole.

[0009] Preferably, the promoting mechanism includes a rubber sleeve, which is fixedly installed on the arc surface of the roller, and a threaded band is fixedly installed on the arc surface of the rubber sleeve, and the arc surface of the threaded band has a groove.

[0010] Preferably, the number of grooves is set to several, and the several grooves are evenly distributed on the arc surface of the threaded strip. The arrangement of multiple grooves allows the rubber sleeve to better fit the surface of the housing.

[0011] Preferably, the auxiliary block is disc-shaped at the end near the reset spring and trapezoidal at the end away from the reset spring, so that the auxiliary block can fit against the surface of the housing and have a centering effect on the housing.

[0012] Preferably, the surface of the vertical plate is provided with an installation groove, the height of which is adapted to the height of the roller, so that the machine casing is guided by the roller to enter the designated position for fixing.

[0013] Preferably, the shape of the frame formed by the vertical plate and the horizontal plate is adapted to the shape of the housing, which facilitates the limiting of the housing and makes the fixing of the housing more stable.

[0014] Preferably, the shape of the mounting hole is adapted to the shape of the auxiliary block, so that the auxiliary block can move inside the mounting hole.

[0015] Compared with the prior art, this utility model provides a tooling fixture for machining compressor housings, which has the following advantages:

[0016] 1. This tooling fixture for processing compressor housing, through the setting of a limit mechanism, pushes the housing into the designated position. Under the guidance of the rollers on the vertical plate, the housing is easily moved. With the help of the return spring and auxiliary blocks, the housing is guided on both sides to center the housing. The arc-shaped setting of the auxiliary blocks and the rollers on the surface facilitate the movement of the housing. After the housing is moved to the appropriate position, the electric push rod moves the clamping plate to fix the housing, ensuring the stability of the housing clamping and ensuring the accuracy of processing.

[0017] 2. The tooling fixture for processing the compressor housing is equipped with a facilitating mechanism and a rubber sleeve, which allows the rollers to better fit the surface of the housing. The combination of threaded strips and grooves increases the contact area, ensuring the stability of the housing movement. At the same time, it has a limiting effect in the vertical direction, reducing the possibility of the housing tilting or tilting during movement and ensuring the stability of the housing clamping.

The limiting mechanism 3 includes a vertical plate 301, a horizontal plate 302, a roller 303, a mounting hole 304, a return spring 305, an auxiliary block 306, a rotating hole 307, and a roller 308.

[0024] In one embodiment of this utility model, a vertical plate 301 is fixedly installed on the upper surface of the mounting platform 1, a horizontal plate 302 is fixedly installed on the side wall of the vertical plate 301, a roller 303 is rotatably installed on the side wall of the vertical plate 301, a mounting hole 304 is opened on the side wall of the vertical plate 301, a return spring 305 is fixedly installed on the inner wall of the mounting hole 304, an auxiliary block 306 is fixedly installed on the end of the return spring 305 away from the inner wall of the mounting hole 304, a rotating hole 307 is opened on the side wall of the auxiliary block 306, and a roller 308 is rotatably connected to the inner wall of the rotating hole 307.

[0025] In addition, the promoting mechanism 4 includes a rubber sleeve 401, which is fixedly installed on the arc surface of the roller 308. A threaded band 402 is fixedly installed on the arc surface of the rubber sleeve 401. The arc surface of the threaded band 402 has grooves 403. The number of grooves 403 is set to several, and the grooves 403 are evenly distributed on the arc surface of the threaded band 402. The arrangement of multiple grooves 403 makes the rubber sleeve 401 fit better against the surface of the machine housing.

[0026] In this embodiment of the utility model, the auxiliary block 306 is disc-shaped at one end near the return spring 305, and trapezoidal at the other end away from the return spring 305. This allows the auxiliary block 306 to fit against the surface of the housing, providing a centering effect. The surface of the vertical plate 301 has an installation groove, the height of which is adapted to the height of the roller 303, allowing the housing to be guided by the roller 303 to enter a designated position for fixation. The shape of the frame formed by the vertical plate 301 and the horizontal plate 302 is adapted to the shape of the housing, facilitating the limiting of the housing and making the fixation of the housing more stable. The shape of the mounting hole 304 is adapted to the shape of the auxiliary block 306, allowing the auxiliary block 306 to move inside the mounting hole 304.

[0027] In this utility model, during use, the machine housing is pushed into the designated position. Guided by the roller 303 on the vertical plate 301, the machine housing is easily moved. With the help of the return spring 305 and the auxiliary block 306, the machine housing is guided on both sides to center the machine housing. The arc-shaped setting of the auxiliary block 306 and the roller 308 on the surface facilitate the movement of the machine housing, allowing it to move to the appropriate position. Subsequently, the electric push rod 5 moves the clamping plate 6 to fix the machine housing, ensuring the stability of the machine housing clamping and ensuring the accuracy of processing.

[0028] Furthermore, the rubber sleeve 401 allows the roller 308 to better fit the surface of the housing. Combined with the threaded band 402 and the groove 403, the contact area is increased, ensuring the stability of the housing movement. At the same time, it has a limiting effect in the vertical direction, reducing the possibility of the housing tilting or tilting during movement and ensuring the stability of the housing clamping.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
