Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning technology, and in particular to a tooling for processing the rear cover of an automotive air conditioning compressor. Background Technology

[0002] The rear cover of an automotive air conditioning compressor is an important component of the compressor. It is usually located at the rear of the compressor and is used to enclose and protect the internal mechanical structure of the compressor.

[0003] However, the following defects still exist: during the manufacturing process, metal shavings or welding slag generated by machining may remain on or inside the rear cover. If not thoroughly ground and cleaned, these impurities will enter the lubrication system or cylinder, causing scratches on the friction pair surface and shortening the valve life. However, most existing grinding and clamping fixtures only fix rear covers of fixed size, which is not convenient to adapt to the clamping of rear covers of different sizes. In order to better address the above problems, promote the development of industry technology, and improve core competitiveness, this application proposes a fixture for processing the rear cover of an automotive air conditioning compressor. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a tooling for processing the rear cover of an automotive air conditioning compressor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tooling for processing the rear cover of an automotive air conditioning compressor includes a base. An electric push rod is fixedly connected to the top and center of the base. The telescopic end of the electric push rod is connected to a connecting shaft via a coupling. Two limiting blocks are detachably connected to the top of the connecting shaft via bolts. A limiting plate that contacts the bottom of one of the limiting blocks is slidably connected to the outer circumference of the connecting shaft. The bottom of the limiting plate contacts the top of the other limiting block. Multiple connecting plates are rotatably connected to the outer side of the limiting plate via multiple bearing seats. A slider is rotatably connected to one end of the connecting plate via a rotating shaft. Multiple evenly distributed support columns are fixedly connected to the top of the base. A fixing plate is fixedly connected to the top of the support columns. The top of the fixing plate has multiple slots that slidably connect with the slider.

[0007] As a further embodiment of this utility model, the top of the slider is provided with a sliding groove, a clamping block is slidably connected in the sliding groove, a plug is fixedly connected to the bottom of the sliding groove, and the bottom of the clamping block is provided with a plug hole for insertion into the plug.

[0008] As a further embodiment of this utility model, the top of the clamping block is connected to a pressure plate via a hinge, and the bottom of the pressure plate contacts the top of the slider.

[0009] As a further improvement of this utility model, the inner walls on both sides of the plurality of slots are provided with clearance grooves, and the slider slides in the clearance grooves.

[0010] As a further embodiment of this utility model, a bracket is detachably connected to the top of the fixed plate and at its center position by bolts, and a rubber pad is fixedly connected to the top of the bracket.

[0011] As a further embodiment of this invention, a turntable is fixedly connected to the outer side of the fixed disk.

[0012] As a further embodiment of this invention, the outer circumferential walls of the plurality of support columns are slidably connected to a fixing frame.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model achieves clamping of compressor back covers of different sizes through the interaction of multiple sliders, slots, connecting plates and electric push rods, which solves the limitation of clamping only compressor back covers of fixed size and improves the flexibility and practicality of the device.

[0021] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Therefore, all other embodiments of this application described herein, and all embodiments obtained by those skilled in the art without creative effort based on the embodiments in this application, should fall within the scope of protection of this application.

[0022] Reference Figures 1-3 A tooling for processing the rear cover of an automotive air conditioning compressor includes a base 7. An electric push rod 13 is fixed to the top of the base 7 and at its center by bolts. The telescopic end of the electric push rod 13 is connected to a connecting shaft 12 via a coupling. The top of the connecting shaft 12 is detachably connected to two limiting blocks 10 by bolts. A limiting plate 14 is slidably connected to the outer circumference of the connecting shaft 12 and contacts the bottom of one of the limiting blocks 10. The bottom of the limiting plate 14 contacts the top of the other limiting block 10.

[0023] Multiple connecting plates 15 are rotatably connected to the outer side of the limiting plate 14 via multiple bearing seats. One end of the connecting plate 15 is rotatably connected to a slider 4 via a rotating shaft. The top of the slider 4 is provided with a sliding groove 16. A clamping block 2 is slidably connected in the sliding groove 16. A plug post 17 is fixed to the bottom of the sliding groove 16 by bolts. The bottom of the clamping block 2 is provided with a plug hole 18 that mates with the plug post 17. The sliding groove 16 is used to provide a fixed position. The plug post 17 is fixed to its bottom for connection and positioning with the clamping block 2. The bottom of the clamping block 2 is provided with a plug hole 18 that matches the plug post 17. By aligning the plug hole 18 below the clamping block 2 with the plug post 17 in the sliding groove 16 and performing the plug-in action, the clamping block 2 can be firmly fixed on the sliding groove 16, making it easy to replace the clamping block 2.

[0024] The top of the base 7 is fixed with multiple evenly distributed support columns 8 by bolts. The outer circumferential walls of the multiple support columns 8 are slidably connected with a fixing frame 11. The fixing frame 11 itself is an elastic component that can appropriately lock the tool through its own elastic properties, ensuring that the tool will not slip off during storage and will not be damaged.

[0025] The top of the support column 8 is fixed with a fixing plate 9 by bolts. The top of the fixing plate 9 has multiple slots 19 that are slidably connected to the slider 4. The inner walls on both sides of the multiple slots 19 are provided with relief grooves 6. The inner walls of the relief grooves 6 are inclined towards the center, and the contact surface between the slider 4 and the relief grooves 6 is also inclined, so that the slider 4 can slide in the relief grooves 6. The function of the relief grooves 6 is to provide a guide path for the slider 4, ensure that the slider 4 slides stably in the relief grooves 6, and prevent it from deviating or leaving the track in the slots 19, thereby maintaining the accuracy and reliability of the action.

[0026] The electric push rod 13 provides power by starting, which drives the connecting shaft 12 to move downward. The limiting block 10 at the top of the connecting shaft 12 will apply downward pressure to the limiting plate 14, causing the limiting plate 14 to move downward. The limiting plate 14 then drives multiple connecting plates 15 to rotate synchronously through the bearing seat on it. Due to the inclination of the inner wall of the relief groove 6, multiple sliders 4 slide along the corresponding slots 19 at the top of the fixed plate 9 to the center position of the fixed plate 9, thereby achieving stable clamping of the compressor rear cover. During this process, manual assistance can be provided to push the sliders 4 along the relief groove 6 to make them fit tightly against the compressor rear cover.

[0027] Alternatively, multiple sliders 4 can be manually pushed to the center position to clamp the compressor back cover, and then the electric push rod 13 can be lowered while pushing and lowering, eventually stabilizing the compressor back cover.

[0028] In this invention, the top of the clamping block 2 is connected to the pressure plate 1 via a hinge, and the bottom of the pressure plate 1 contacts the top of the slider 4. The pressure plate 1 is a magnetic plate, which can use its own magnetic attraction force to firmly fix the clamping block 2 in the slide groove 16, ensuring its stability and reliability during operation. This allows the clamping block 2 to be accurately installed and subjected to force. When it is necessary to replace the clamping block 2 that has failed due to wear, it can be easily replaced simply by opening the pressure plate 1 without complicated disassembly, which greatly improves the convenience of replacing the clamping block 2.

[0029] In this utility model, a bracket 3 is detachably connected to the top of the fixed plate 9 and located at the center position by bolts. A rubber pad is fixedly connected to the top of the bracket 3. The bracket 3 fixes the compressor back cover to be polished at the top center position, effectively preventing it from sliding during the polishing process. The anti-slip pad further increases the friction and ensures the stability of the compressor back cover when it is clamped. The bracket 3 can be replaced according to the compressor back cover of different sizes, which improves the flexibility and adaptability of the polishing work.

[0030] The outer side of the fixed plate 9 is fixed with a turntable 5 by bolts. The function of the turntable 5 is to flexibly adjust the position of the compressor back cover through its rotation function, so that it can be rotated to different angles during grinding, thereby improving the flexibility of the grinding work. Through the rotation of the turntable 5, the compressor back cover can move relative to the grinding tool, ensuring that all parts of its surface can be fully ground, thus improving grinding efficiency and quality.

[0031] Working principle: When needed, according to the size of the compressor back cover, the bracket 3 is fixed to the center of the fixed plate 9 with bolts. Then, the compressor back cover to be polished is fixed to the top center of the bracket 3. The electric push rod 13 is started, which drives the connecting shaft 12 to move downward. The limiting block 10 at the top of the connecting shaft 12 applies downward pressure to the limiting plate 14, causing the limiting plate 14 to move downward. The limiting plate 14 drives multiple connecting plates 15 to rotate synchronously through the bearing seat on it, moving along the relief groove 6, thereby driving multiple sliders 4 to slide along the corresponding groove 19 on the top of the fixed plate 9 to the center of the fixed plate 9, thereby clamping the compressor back cover. During this process, manual assistance can be provided to push the multiple sliders 4 to the center position to clamp the compressor back cover, making it fit tightly and quickly. Rotate the turntable 5 until the entire device is adjusted to the required position. Finally, other operations on the compressor back cover can be performed using external equipment.

[0032] This utility model has been described through the above embodiments. Those skilled in the art will understand that this utility model is not limited to the above embodiments. Many more modifications can be made based on the teachings of this utility model, and all such modifications fall within the scope of protection claimed by this utility model.
