Description

Technical Field

[0001] The present invention mainly relates to a technical field, specifically to a tool for processing a rear cover of an automobile air-conditioning compressor. Background Art

[0002] The rear cover of the compressor is made of metal. When the rear cover is assembled with the compressor shell, it needs to be processed. Before processing, the rear cover needs to be clamped and limited by the processing tooling.

[0003] It is difficult for the tooling used for processing the rear cover of the automobile air-conditioning compressor to adjust the clamping effect of the tooling according to the surface shape of the rear cover of the air-conditioning compressor, which affects the applicability of the tooling, and it is difficult to clamp the rear cover of the air-conditioning compressor tightly, which affects the subsequent processing of the rear cover. Summary of the invention

[0004] The present invention mainly provides a tool for processing a rear cover of an automobile air-conditioning compressor to solve the technical problems raised in the above-mentioned background technology.

[0005] The technical solution adopted by the present invention to solve the above technical problems is:

[0006] A tool for processing a rear cover of an automobile air-conditioning compressor, comprising a tooling table, the upper surface of which is connected with a clamp;

[0007] The fixture includes a cylinder connected to the upper surface of the workbench, a pressure plate connected to the top end of the piston rod of the cylinder, and a support plate connected to one side surface of the cylinder;

[0008] The bottom end of the cylinder is connected with an angle adjustment component, and the bottom end of the cylinder is connected to the tooling table through the angle adjustment component.

[0009] Furthermore, an opening is provided at one end of the pressure plate, and the opening is used for allowing the piston rod of the cylinder to pass through. The pressure plate is connected to the piston rod of the cylinder through a rotating shaft. In the present invention, the pressure plate accommodates the piston rod of the cylinder through the opening. Since the pressure plate is connected to the piston rod of the cylinder through the rotating shaft, the piston rod of the cylinder can push the pressure plate to rotate.

[0010] Furthermore, the top of the cylinder is connected with symmetrically arranged protrusions, and the side surfaces of the protrusions close to each other are rotatably connected with a connecting rod via a rotating shaft, and the end of the connecting rod away from the protrusion is rotatably connected to the pressure plate via the rotating shaft. In the present invention, when the pressure plate is pushed by the piston rod of the cylinder, since the connecting rod is respectively connected to the pressure plate and the protrusion through the rotating shaft, it does not interfere with the pushing of the piston rod of the cylinder.

[0011] Furthermore, the angle adjustment assembly includes a bolt connected to the bottom end of the cylinder, the bottom end of the cylinder is connected to a polygonal head by the bolt, and the bottom end of the cylinder is provided with a groove for accommodating the bolt. In the present invention, the polygonal head at the bottom end of the cylinder is inserted into the groove at the top end of the workbench, thereby limiting the movement of the polygonal head by the groove body of the groove.

[0012] Furthermore, a plurality of grooves are provided on the top of the workbench, and the cross-section of the grooves is polygonal. The grooves are used to accommodate the polygonal head. In the present invention, the position of the cylinder can be adjusted in steps through the polygonal grooves.

[0013] Furthermore, the support plate is a hollow structure, and a plurality of first spring rods are connected to the upper surface of the support plate, and the plurality of first spring rods are arranged in an array, and the first spring rods include a guide rod connected to the inside of the support plate, and a pressure sleeve sleeved on the outside of the guide rod body, and the inner wall of the pressure sleeve is slidably connected to the outer surface of the guide rod. In the present invention, when the pressure plate rotates, the first spring rod is extended and retracted by sliding the pressure sleeve on the guide rod body, so that when the first spring rod is squeezed and extended by the rear cover of the automobile air-conditioning compressor, the plurality of first spring rods form grooves that fit with the surface of the rear cover.

[0014] Furthermore, a spring is sleeved on the outside of the rod body of the guide rod, one end of the spring abuts against the bottom end of the pressure sleeve, and the other end of the spring abuts against the inner wall of the support plate. In the present invention, the spring is set to push the pressure sleeve tightly against the back cover to tightly press the back cover.

[0015] Furthermore, a plurality of second spring rods arranged in an array are connected to the bottom of the plate body of the pressure plate, and the second spring rods have the same structure as the first spring rods. In the present invention, the second spring rods are extended and retracted to adapt to the shape of the rear cover of the air-conditioning compressor, thereby improving the clamping effect of the rear cover.

[0016] Furthermore, the rotating shaft at the top end of the connecting rod is fixedly connected to the connecting rod, and a cavity for accommodating the second spring rod is provided on the plate body of the pressure plate. In the present invention, the rotating shaft at the top end of the connecting rod extends into the cavity, so that when relative rotation occurs between the pressure plate and the piston rod of the cylinder, the arc-shaped slider is pushed by the push bar on the rotating shaft, so that the arc-shaped slider squeezes the multiple second spring rods to tighten the grooves formed by the second spring rods, thereby further improving the clamping effect on the rear cover of the air-conditioning compressor.

[0017] Furthermore, the rotating shaft at the top end of the connecting rod extends into the cavity and is connected to a push bar, one side of the push bar is abutted with an arc-shaped slider, and one end of the arc-shaped slider away from the push bar is abutted with the second spring rod.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] Firstly, the present invention inserts the polygonal head at the bottom end of the cylinder into the groove at the top end of the workbench, thereby limiting the movement of the polygonal head through the groove body of the groove, thereby limiting the movement of the cylinder, so that the cylinder can be stably installed on the workbench, and the position and angle of the cylinder can be adjusted in the above manner.

[0020] Secondly, the present invention drives the pressure plate to rotate by the cylinder. When the pressure plate rotates, the pressure sleeve slides on the guide rod body, thereby realizing the extension and retraction of the first spring rod. When the first spring rod is squeezed by the rear cover of the automobile air-conditioning compressor and extends and retracts, multiple first spring rods form grooves that fit with the surface of the rear cover. Through the extension and retraction of the second spring rod, it adapts to the shape of the rear cover of the air-conditioning compressor and improves the clamping effect of the rear cover.

[0031] For examples, please refer to the attached Figure 1-5 , a tool for processing a rear cover of an automobile air-conditioning compressor, comprising a tooling table 10, wherein a fixture 20 is connected to the upper surface of the tooling table 10;

[0032] The fixture 20 includes a cylinder 21 connected to the upper surface of the workbench 10, a pressure plate 22 connected to the top of the piston rod of the cylinder 21, and a support plate 23 connected to one side surface of the cylinder 21;

[0033] The bottom end of the cylinder 21 is connected to an angle adjustment component 24 , and the bottom end of the cylinder 21 is connected to the workbench 10 via the angle adjustment component 24 .

[0034] For details, please refer to the attached Figure 2 and 3 One end of the pressing plate 22 is provided with an opening 221, and the opening 221 is used for the piston rod of the cylinder 21 to pass through. The pressing plate 22 is connected to the piston rod of the cylinder 21 through a rotating shaft;

[0035] The top of the cylinder 21 is connected with symmetrically arranged protrusions 211, and the surfaces of the protrusions 211 close to each other are rotatably connected with a connecting rod 212 via a rotating shaft, and the end of the connecting rod 212 away from the protrusion 211 is rotatably connected with the pressure plate 22 via a rotating shaft;

[0036] It should be noted that, in this embodiment, the pressing plate 22 accommodates the piston rod of the cylinder 21 through the opening 221. Since the pressing plate 22 is connected to the piston rod of the cylinder 21 through the rotating shaft, the piston rod of the cylinder 21 can push the pressing plate 22 to rotate.

[0037] Furthermore, the connecting rod 212 provides support for the pressure plate 22, and the protrusion 211 provides support for the connecting rod 212.

[0040] It should be noted that, in this embodiment, the polygonal head 242 at the bottom end of the cylinder 21 is inserted into the groove 11 at the top end of the workbench 10, so that the movement of the polygonal head 242 is limited by the groove body of the groove 11, thereby limiting the movement of the cylinder 21, so that the cylinder 21 is stably installed on the workbench 10;

[0041] Furthermore, the position of the cylinder 21 can be adjusted in steps through the polygonal groove 11 .

[0042] For details, please refer to the attached Figure 2 and 3 The support plate 23 is a hollow structure, and a plurality of first spring rods 231 are connected to the upper surface of the support plate 23. The plurality of first spring rods 231 are arranged in an array, and the first spring rods 231 include a guide rod 2311 connected to the inside of the support plate 23, and a pressure sleeve 2312 sleeved on the outside of the guide rod 2311.

[0046] Furthermore, by setting the spring 2313, the pressure sleeve 2312 is pushed to be close to the rear cover, so as to press the rear cover tightly;

[0047] Furthermore, by extending and retracting the second spring rod 223, the shape of the rear cover of the air-conditioning compressor is adapted to improve the clamping effect of the rear cover.

[0048] For details, please refer to the attached Figure 4 and 5 The rotating shaft at the top of the connecting rod 212 is fixedly connected to the connecting rod 212, and a cavity 222 for accommodating the second spring rod 223 is provided on the plate body of the pressing plate 22;

[0051] The specific operation mode of the present invention is as follows:

[0052] When using the tooling for processing the rear cover of the automobile air-conditioning compressor, the polygonal head 242 at the bottom end of the cylinder 21 is inserted into the groove 11 at the top end of the tooling table 10, so that the movement of the polygonal head 242 is limited by the groove body of the groove 11, thereby limiting the movement of the cylinder 21, so that the cylinder 21 is stably installed on the tooling table 10. In this way, the position and angle of the cylinder 21 are adjusted;

[0053] The cylinder 21 pushes the pressure plate 22 to rotate. When the pressure plate 22 rotates, the pressure sleeve 2312 slides on the rod body of the guide rod 2311, thereby realizing the extension and retraction of the first spring rod 231. When the first spring rod 231 is squeezed and extended by the rear cover of the automobile air-conditioning compressor, multiple first spring rods 231 form grooves that fit with the surface of the rear cover. Through the extension and retraction of the second spring rod 223, it adapts to the shape of the rear cover of the air-conditioning compressor and improves the clamping effect of the rear cover.
