Technical Field
[0001] This utility model relates to the field of air conditioner compressor manufacturing technology, specifically to a pre-assembly fixture for the front and rear end plates of an air conditioner compressor cylinder. Background Technology
[0002] As the core component of an air conditioning system, the performance of the air conditioning compressor directly affects the operating efficiency and cooling effect of the entire system. In the manufacturing process of an air conditioning compressor, the pre-assembly of the front and rear end plates of the cylinder block is a crucial step.
[0003] The structural design of tooling typically includes components such as a base plate, upright plates, connecting rods, baffles, and support plates. Taking an automotive air conditioning compressor as an example, during pre-assembly, tooling ensures accurate alignment and secure clamping of the front and rear end plates of the compressor cylinder, thereby improving pre-assembly efficiency and quality.
[0004] During the pre-assembly process, the front and rear end plates of the cylinder block may be misaligned due to the lack of precise guiding and positioning devices. Inaccurate positioning will directly affect the sealing performance and operating efficiency of the compressor. Therefore, a pre-assembly fixture for the front and rear end plates of the air conditioning compressor cylinder block is proposed to address the above issues. Utility Model Content
[0005] To overcome the shortcomings of existing technology, during the pre-assembly process, the front and rear end plates of the cylinder block may have deviations in installation position due to the lack of precise guiding and positioning devices. Inaccurate positioning will directly affect the sealing performance and operating efficiency of the compressor. This utility model proposes a pre-assembly fixture for the front and rear end plates of the air conditioning compressor cylinder block.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The pre-assembly fixture for the front and rear end plates of the air conditioning compressor cylinder of this utility model includes a base; a pre-assembly platform is fixedly installed on the upper part of the base, and columns are fixedly installed on both sides of the middle of the pre-assembly platform. A sliding groove is opened on the opposite side of each column, and a control box is arranged between the columns. Both ends of the control box are slidably arranged in the sliding groove. A guide rod is fixedly installed inside the control box, and a sliding plate is slidably arranged inside both ends of the control box. A through hole is opened inside the upper end of the sliding plate, and the lower end penetrates the control box and a clamping plate is fixedly installed on the inner side. The sliding plate is slidably installed at both ends of the guide rod. Limit rods are fixedly installed on both sides of the upper part of the pre-assembly platform, and sliding tables are slidably installed at both ends of the limit rods. A groove is opened at the upper end of each sliding table, and a bidirectional screw is rotatably installed inside the groove. Fixed plates are installed at both ends of the groove, and threaded holes are opened in the lower end of the fixed plates. The fixed plates are slidably installed at both ends of the first bidirectional screw. Second clamping plates are fixedly installed on the inner side of the upper end of the fixed plates. A belt conveyor is fixedly installed on the upper part of the base below the first clamping plate. Slide rails are fixedly installed on the upper part of both ends of the base. Support plates are installed on both sides of the belt conveyor. Positioning seats are fixedly installed on the top of the support plates. Multiple rollers are rotatably installed in parallel inside the positioning seats. The bottom ends of both ends of the support plates are slidably installed in the slide rails, and threaded holes are opened in the center of the lower end of the support plates. By using the slide plate and the first clamping plate in the control box, as well as the groove, the first bidirectional screw, and the second clamping plate on the slide table, the precise positioning and stable clamping of the front and rear end plates of the cylinder can be achieved, thereby simplifying the pre-assembly process and improving the pre-assembly efficiency and accuracy.
[0007] Preferably, a No. 1 cylinder is fixedly installed on the top of each column, and the piston rod of the No. 1 cylinder is fixedly installed on both sides of the top of the control box. By introducing the No. 1 cylinder, the control box can move flexibly up and down along the column.
[0008] Preferably, a second cylinder is fixedly installed on the top of the control box, and a mounting base is fixedly installed on the piston rod of the second cylinder. Connecting rods are rotatably installed on both sides of the mounting base, and the other end of the connecting rod is rotatably installed on the top of the slide plate. By setting up the second cylinder, the introduction of the second cylinder makes the movement of the slide plate faster and more efficient. Compared with traditional mechanical drive or manual operation, the cylinder has a greater driving force and a faster action, thereby significantly improving the overall efficiency of the pre-assembly process.
[0009] Preferably, a control motor is fixedly installed at one end of each slide table, and the rotating shaft of the control motor is fixedly connected to one end of the No. 1 bidirectional screw. By setting the control motor, not only is stable clamping of the front and rear end plates of the cylinder achieved, but the clamping process is also more controllable and precise.
[0010] Preferably, a No. 3 cylinder is fixedly installed at both ends of the pre-assembly platform, and the piston rod of the No. 3 cylinder is fixedly installed on the slide. By setting the No. 3 cylinder, when the piston rod of the No. 3 cylinder extends or retracts, it can push the slide to move left and right on the limit rod, which not only enhances the flexibility of the pre-assembly device, but also can adapt to the front and rear end plates of cylinders of different lengths.
[0011] Preferably, a second bidirectional screw is provided between the slide rails. Both ends of the second bidirectional screw are rotatably mounted on the upper part of the base via bearings. A drive motor is fixedly mounted on the upper part of the base at one end of the second bidirectional screw. The rotating shaft of the drive motor is fixedly connected to one end of the second bidirectional screw. The support plates are slidably mounted on both ends of the second bidirectional screw. By providing the drive motor, the rotation of the drive motor can drive the second bidirectional screw to rotate, and then push the support plates to move left and right on the slide rail through the transmission action of the screw thread. This not only achieves precise adjustment of the positioning seat, but also allows the entire pre-assembly device to adapt to the front and rear end plates of cylinders of different sizes.
[0012] The advantages of this utility model are:
[0013] 1. This utility model, during the compressor assembly process, uses pre-assembly fixtures to pre-assemble the compressor cylinder body and front and rear end plates. The compressor cylinder body is placed on a belt conveyor, and then transported to below the first clamping plate via the conveyor belt. Rollers are used to position both ends of the cylinder body. Then, the first cylinder is activated, moving the first clamping plate to both sides of the cylinder body. Next, the second cylinder is activated, using a mounting base to drive a connecting rod that pulls a sliding plate within the control box. The sliding plate moves the first clamping plate to clamp and fix both sides of the cylinder body. Finally, the cylinder body is lifted to the upper part of the pre-assembly platform, and the control motor is started, using the first... The bidirectional screw drives the No. 2 clamping plate to fix the front and rear end plates onto the slide. The No. 3 cylinder is activated to push the slide, moving the end plates to both ends of the cylinder body for pre-assembly. This structural design achieves precise positioning and stable clamping, solving the problem that the front and rear end plates of the cylinder body may deviate in installation position during pre-assembly due to the lack of precise guiding and positioning devices. Inaccurate positioning directly affects the sealing performance and operating efficiency of the compressor. This improves the accuracy and efficiency of the pre-assembly process, reduces production and maintenance costs, and enhances the convenience of operation and the adaptability of the equipment.
