Description

Technical Field

[0001] This utility model relates to the field of compressor cylinder assembly technology, specifically a positioning and assembly mechanism for compressor cylinders. Background Technology

[0002] The air conditioning compressor is the core component of an air conditioning system, and its quality directly affects the overall cooling efficiency, operational stability, and service life of the unit. The internal cylinder structure of a compressor typically includes a cylinder top cover, cylinder body, cylinder bottom cover, and a crankshaft that runs through the assembly. The cylinder body contains a gas chamber for mounting the piston assembly to compress the gas. To ensure assembly precision and sealing, specialized cylinder tooling is commonly used for positioning and press-fitting during production. Good assembly processes are crucial for ensuring cylinder coaxiality and reducing leakage; therefore, the rationality of tooling design directly affects the overall performance and reliability of the compressor.

[0003] Currently, commonly used cylinder assembly fixtures mainly consist of an assembly table and a circumferentially arranged positioning mechanism. During assembly, the cylinder top cover is first positioned on the assembly table, and then the cylinder body, crankshaft, and piston assembly are stacked sequentially. However, existing fixtures often use the method of placing the entire cylinder on the table. After assembly, the entire cylinder assembly must be removed before the next round of assembly can begin. This method results in frequent cylinder body removal and placement operations, repetitive positioning, and a long auxiliary time, reducing the production cycle time and making it difficult to meet the requirements of efficient continuous assembly, thus limiting the efficiency improvement of compressor mass production.

[0004] Based on this, a positioning and assembly mechanism for compressor cylinders is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, such as Figures 1-7 As shown, a positioning and assembly mechanism for a compressor cylinder includes a transmission belt 11 and positioning components. Two transmission belts 11 are symmetrically arranged inside a mounting box 12. Several positioning components are equally spaced between the two transmission belts 11. The mounting box 12 is equipped with a drive component for intermittently moving the positioning components. Each positioning component includes a bearing seat 14. Each bearing seat 14 is fixedly connected to the transmission belt 11 by a fixing rod. Each bearing seat 14 has a positioning groove 15 at its upper end for positioning the cylinder body 25. Each bearing seat 14 is equipped with a limiting component for limiting the position of the cylinder body 25. The limiting component facilitates the limiting and fixing of the cylinder body 25, thereby preventing the cylinder body 25 from shaking during assembly.

[0026] The driving component includes a drive roller and a transmission roller at both ends of a transmission belt 11. The rotating shafts at one end of the drive roller and the transmission roller are rotatably disposed in the rotating holes inside the mounting box 12. A fixed shaft is fixedly disposed between the drive roller and the transmission roller on the same axis. One rotating shaft at one end of the drive roller is fixedly connected to the output end of the motor 13. The motor 13 is fixedly disposed on one side of the mounting box 12. In use, when the cylinder needs to be assembled, the output end of the motor 13 drives the two transmission belts 11 to rotate intermittently. The transmission belts 11 drive the bearing seat 14 to rotate. When the bearing seat 14 rotates to the upper end of the transmission belt 11 and stops, the operator places the cylinder body 25 inside the positioning groove 15. The positioning groove 15 can position the cylinder body 25. Then the transmission belt 11 continues to drive the bearing seat 14 to move intermittently, which facilitates the installation of other components into the cylinder body 25.

[0027] The limiting component includes a limiting frame 16. Each of the bearing seats 14 has a mounting groove at its bottom. The limiting frames 16 are symmetrically arranged within each mounting groove. Guide rods are slidably mounted on each limiting frame 16 and fixedly mounted within the mounting groove. A first tension spring 17 is provided between one side of each limiting frame 16 and one side of the mounting groove. Connecting rods 18 are hinged to the other end of each limiting frame 16. The other ends of the two connecting rods 18 are respectively hinged to both ends of a hinge rod 19. A top rod 20 is fixedly mounted at the bottom end of each hinge rod 19. A limiting block is slidably mounted on each top rod 20 and fixedly mounted within the mounting groove. Extension plates are symmetrically arranged on the hinge rod 19, and a second tension spring 21 is fixedly mounted at the bottom end of each extension plate. The other end of the second tension spring 21 is fixedly connected to the bottom of the mounting groove. A guide plate 22 is fixedly provided inside the mounting box 12 at the position of the top rod 20. The guide plate 22 is in close contact with one end of the top rod 20 at the upper end of the transmission belt 11. Several support frames are fixedly provided on the guide plate 22. The support frames are fixedly provided inside the mounting box 12. In use, when the cylinder body 25 is placed inside the positioning groove 15, during the process of the transmission belt 11 driving the bearing seat 14 to move again, one end of the top rod 20 is in close contact with the guide plate 22. The guide plate 22 guides the top rod 20, so that the top rod 20 pushes the hinge rod 19 to slide. The hinge rod 19 pulls the limiting frame 16 to slide through the connecting rod 18, so that one end of the limiting frame 16 limits and fixes one end of the cylinder body 25.

[0028] Both ends of the guide plate 22 are inclined, and one end of the push rod 20 is provided with a ball bearing, which helps to reduce wear between one end of the push rod 20 and the upper end of the guide plate 22 during use.

[0029] The bearing seat 14 is symmetrically provided with mounting rods at both ends, and each mounting rod is provided with a roller 23 at one end. The inner side of the mounting box 12 is provided with support plates 24 at the upper and lower ends of the bearing seat 14 of the transmission belt 11. The support plates 24 are in close contact with the rollers 23. In use, they can easily support the bearing seat 14 and prevent the transmission belt 11 from bending during assembly.

[0030] Auxiliary support rods are symmetrically provided at the bottom end of the bearing seat 14 and at the corresponding positions of the transmission belt 11. The cross-section of the auxiliary support rods is T-shaped, which facilitates the auxiliary support of the bearing seat 14 during use.

[0031] The above embodiment discloses a positioning and assembly mechanism for a compressor cylinder. When the cylinder needs to be assembled, the output end of the motor 13 drives two transmission belts 11 to rotate intermittently. The transmission belts 11 drive the bearing seat 14 to rotate. When the bearing seat 14 stops rotating at the upper end of the transmission belt 11, the operator places the cylinder body 25 inside the positioning groove 15. The positioning groove 15 can position the cylinder body 25. During the process of the transmission belt 11 driving the bearing seat 14 to move again, the push rod 20 is in close contact with one end of the guide plate 22. The guide plate 22 guides the push rod 20, so that the push rod 20 pushes the hinge rod 19 to slide. The hinge rod 19 pulls the limiting frame 16 to slide through the connecting rod 18, so that one end of the limiting frame 16 limits and fixes one end of the cylinder body 25. The transmission belt 11 continues to drive the bearing seat 14 to move intermittently, which facilitates the installation of other components into the cylinder body 25.

[0032] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
