Description

Technical Field

[0001] This utility model relates to the field of piston clamping technology, and in particular to a novel piston spraying clamp. Background Technology

[0002] The B5GP compressor, a variable displacement air conditioner compressor in automobiles, serves as the "power core" of the air conditioning system and is a key component for achieving cooling or heating cycles. Its core function is to use a motor to draw in low-temperature, low-pressure refrigerant gas from the evaporator, and then use an internal moving mechanism to compress the refrigerant, transforming it into a high-temperature, high-pressure gas, which is then delivered to the condenser. This, in turn, drives the refrigerant to continuously circulate within the air conditioning system, ultimately regulating the indoor temperature through heat exchange with the indoor and outdoor air.

[0003] The air conditioner compressor piston is the core component inside the compressor that completes the compression of the refrigerant. In order to balance lightweight and thermal conductivity, it is mostly made of high-strength aluminum alloy, and cast iron is used in some high-pressure conditions. Structurally, it is cylindrical or stepped cylindrical, and the top, together with the cylinder wall and cylinder head, forms the "compression chamber".

[0004] In piston manufacturing, the spraying fixture is the core tooling to ensure the quality of the piston surface coating. It needs to achieve two core functions: first, to stably hold the piston and avoid workpiece displacement during the spraying process, which would lead to coating deviation; second, to adapt to the spraying requirements, minimize the obstruction of the piston area to be sprayed, and be compatible with the clamping of pistons of different specifications.

[0005] Currently, most piston coating fixtures in the industry adopt rigid clamping structures, which have significant shortcomings in their overall design. On the one hand, the fixed-size clamping components cannot adapt to piston rods with different bore diameters, requiring frequent replacement of fixture components and resulting in low clamping efficiency. On the other hand, the piston cannot be rotated after clamping, making it difficult to perform all-round spraying. It requires manual rotation of the spray gun to achieve all-round spraying, which easily leads to uneven local spraying and cannot meet the all-round spraying requirements of high-precision pistons, thus restricting the improvement of spraying quality and production efficiency. Therefore, in view of the above situation, there is an urgent need to develop a new type of piston coating fixture that uses a double fixation of an elastic expansion airbag and an electric telescopic rod clamping plate. This fixture can adapt to piston rods with different bore diameters, achieving flexible clamping to protect the workpiece, and can also drive the turntable and piston to rotate 360° through gear transmission, facilitating all-round spraying and effectively improving spraying efficiency and coating uniformity. This new fixture can overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0006] The purpose of this invention is to provide a novel piston spraying fixture to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A novel piston spraying fixture includes a base, a turntable, a positioning baffle, a flexible clamping mechanism, a clamping mechanism, and a rotating mechanism. A rotating shaft is fixed to the bottom of the turntable and rotatably connected to the base. The rotating mechanism is mounted on the base and connected to the rotating shaft. The positioning baffle is fixed to the turntable, and a support rod is fixed to the positioning baffle. The clamping mechanism is mounted on the turntable and faces the positioning baffle. The flexible clamping mechanism includes an elastic expansion airbag, an air pump, an air pipe, a solenoid valve, and an exhaust valve. The elastic expansion airbag is fixed to the outside of the support rod. The air pump is fixed to the turntable and connected to the elastic expansion airbag via the air pipe. The solenoid valve and exhaust valve are mounted on the air pipe.

[0008] Preferably, the clamping mechanism includes an electric telescopic rod and a clamping plate, wherein the electric telescopic rod is fixed on the turntable, and the telescopic end of the electric telescopic rod is fixed to the clamping plate.

[0009] Preferably, the rotating mechanism includes a drive motor, a first gear, and a second gear. The drive motor is fixed on the base, and the first gear is fixed on the output shaft of the drive motor. A second gear is provided on one side of the first gear to mesh with it, and the second gear is fixed on the rotating shaft.

[0010] Preferably, the elastic inflatable airbag is made of silicone rubber.

[0011] The beneficial effects of this utility model are as follows: When using this novel piston spraying fixture, first insert the mounting hole at the lower end of the piston connecting rod into the support rod so that one side of the piston connecting rod is in contact with the positioning baffle. Then, start the air pump to inflate the elastic expansion airbag, causing it to expand. The expansion of the elastic expansion airbag tightens the piston connecting rod mounting hole from the inside, thus initially clamping the piston. The elastic expansion airbag can be used to position piston connecting rods with different hole diameters. Then, the clamping plate is moved by the electric telescopic rod, and the piston connecting rod is clamped to the positioning baffle by the clamping plate. Then, a person uses the spraying equipment to spray the piston. During the spraying process, the drive motor drives the first gear and the second gear to rotate. The rotation of the second gear drives the rotating shaft and the turntable to rotate. The turntable drives the piston to rotate, so as to spray the piston in all directions in 360°. In summary, this utility model, through the dual fixation of the elastic expansion airbag and the electric telescopic rod clamping plate, can not only adapt to piston connecting rods of different apertures to achieve flexible clamping to protect the workpiece, but also drive the turntable and piston to rotate 360° through gear transmission, facilitating comprehensive spraying and effectively improving spraying efficiency and coating uniformity.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Specific implementation examples are given below.

[0020] See Figures 1-5In this embodiment of the present invention, a novel piston spraying fixture includes a base 1, a turntable 2, a positioning baffle 3, a flexible clamping mechanism 4, a clamping mechanism 5, and a rotating mechanism 6. A rotating shaft 201 is fixed to the bottom of the turntable 2 and is rotatably connected to the base 1. The rotating mechanism 6 is mounted on the base 1 and connected to the rotating shaft 201, allowing the rotating shaft 201 and the turntable 2 to rotate. The positioning baffle 3 is fixed to the turntable 2, and a support rod 301 is fixed to the positioning baffle 3. The support rod 301 is used to position and support the mounting hole of the piston connecting rod. The clamping mechanism 5 is mounted on the turntable 2 and faces the positioning baffle 3, clamping the piston connecting rod to the positioning baffle 3. The flexible clamping mechanism 4, the flexible clamping mechanism 5, and the flexible clamping mechanism 6 are all present in the present invention. The clamping mechanism 4 includes: an elastic expansion airbag 401, an air pump 402, an air pipe 403, a solenoid valve 404, and an exhaust valve 405. The elastic expansion airbag 401 is fixed to the outside of the support rod 301. The air pump 402 is fixed to the turntable 2. The air pump 402 is connected to the elastic expansion airbag 401 through the air pipe 403. The solenoid valve 404 and the exhaust valve 405 are installed on the air pipe 403. In use, the mounting hole at the lower end of the piston connecting rod is inserted into the support rod 301, so that one side of the piston connecting rod is in contact with the positioning baffle 3. Then, the air pump 402 is started to inflate the elastic expansion airbag 401, causing it to expand. The expansion of the elastic expansion airbag 401 presses the piston connecting rod mounting hole from the inside, thereby initially clamping the piston.

[0021] The elastic inflatable airbag 401 is made of silicone rubber.

[0022] The clamping mechanism 5 includes an electric telescopic rod 501 and a clamping plate 502. The electric telescopic rod 501 is fixed on the turntable 2. The telescopic end of the electric telescopic rod 501 is fixed to the clamping plate 502. In use, the electric telescopic rod 501 drives the clamping plate 502 to move, and the clamping plate 502 clamps the piston connecting rod onto the positioning baffle 3.

[0023] The rotating mechanism 6 includes a drive motor 601, a first gear 602, and a second gear 603. The drive motor 601 is fixed on the base 1. The first gear 602 is fixed on the output shaft of the drive motor 601. A second gear 603 is provided on one side of the first gear 602 and meshes with it. The second gear 603 is fixed on the rotating shaft 201. In use, the drive motor 601 drives the first gear 602 and the second gear 603 to rotate. The rotation of the second gear 603 drives the rotating shaft 201 and the turntable 2 to rotate. The turntable 2 drives the piston to rotate so as to perform 360° all-round spraying on the piston.

[0024] The air pump 402, solenoid valve 404, exhaust valve 405, electric telescopic rod 501 and drive motor 601 mentioned above are all controlled by a PLC system (not shown in the figure).

[0025] Working principle: When using this new type of piston spraying fixture, first insert the mounting hole at the lower end of the piston connecting rod into the support rod 301, making one side of the piston connecting rod fit against the positioning baffle 3. Then, start the air pump 402 to inflate the elastic expansion airbag 401, causing it to expand. The expansion of the elastic expansion airbag 401 tightens the piston connecting rod mounting hole from the inside, thus initially clamping the piston. The elastic expansion airbag 401 can position piston connecting rods with different hole diameters. Then, the electric telescopic rod 501 drives the clamping plate 502 to move, clamping the piston connecting rod against the positioning baffle 3. Then, a person uses the spraying equipment to spray the piston. During the spraying process, the drive motor 601 drives the first gear 602 and the second gear 603 to rotate. The rotation of the second gear 603 drives the rotating shaft 201 and the turntable 2 to rotate, and the turntable 2 drives the piston to rotate, so as to spray the piston in all directions of 360°.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
