Description

Technical Field

[0001] This utility model relates to the field of bearing testing technology, specifically a device for testing the inner and outer diameters of air conditioning compressor bearings. Background Technology

[0002] With the sustained development of my country's economy and the significant improvement of its technological level, the machinery manufacturing industry has made great strides. As an essential product of modern life, the performance of the compressor—a core component of air conditioners—is crucial. The bearings of air conditioner compressors are key precision parts inside the compressor; the machining accuracy of their inner and outer diameters directly affects the compressor's operating efficiency, noise level, and service life. Therefore, during the manufacturing process, the inner and outer diameter dimensions of the bearings must be rigorously and accurately inspected to ensure they meet design specifications and quality requirements. This inevitably requires specialized high-precision testing equipment to achieve efficient and accurate measurements.

[0003] Currently, in the production and testing of air conditioning compressor bearings, the commonly used traditional method is for operators to manually measure the inner and outer diameters of each bearing one by one using measuring tools such as vernier calipers, micrometers, or internal diameter gauges. This method has significant drawbacks: First, the repetitive manual operation of measuring tools is extremely labor-intensive and easily leads to operator fatigue; second, the testing efficiency is extremely low, making it difficult to match the pace of modern production lines; third, the measurement results are significantly affected by factors such as operator experience, technique, and visual reading errors, making it difficult to effectively guarantee measurement accuracy and consistency, and easily leading to misjudgments or missed detections. These defects seriously restrict the implementation of large-scale, high-efficiency, and high-precision testing of bearings, becoming a bottleneck restricting the improvement of production efficiency and product quality.

[0004] Based on this, an air conditioner compressor bearing inner and outer diameter detection device is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation

[0026] 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.

[0027] Example 1

[0028] In one embodiment, such as Figures 1-7 As shown, an air conditioner compressor bearing inner and outer diameter detection device includes a detection component 11 and a conveyor belt 21. Two detection components 11 are symmetrically arranged and positioned above the two conveyor belts 21. The two conveyor belts 21 are symmetrically arranged inside a mounting box 20. A top frame 19 is fixedly provided at the upper end of the mounting box 20. A drive assembly for moving the detection component 11 is provided on the upper inner side of the top frame 19. Several bearing plates 23 are arranged at equal intervals between the two conveyor belts 21. Each bearing plate 23 is fixedly connected to the two conveyor belts 21 via a connecting rod. A first clamping mechanism and a second clamping mechanism are provided at the upper end of the bearing plate 23 to clamp the inner diameter and outer ring of the bearing body 43, respectively. The first clamping mechanism and the second clamping mechanism are used to position and clamp the outer ring and inner ring of the bearing body 43, thereby facilitating the two detection components 11 to detect the inner diameter and outer diameter of the bearing body 43, respectively.

[0029] Both ends of the conveyor belt 21 are equipped with drive rollers and transmission rollers. A fixed shaft is provided between the two drive rollers and transmission rollers. The other end of the drive roller and transmission roller is rotatably mounted in the rotation hole inside the mounting box 20. One end of the drive roller is fixedly connected to the output end of the second motor 22. The second motor 22 is fixedly mounted on one side of the mounting box 20. In use, when it is necessary to detect the inner and outer diameters of the bearing body 43, the second motor 22 drives the conveyor belt 21 to rotate. The two conveyor belts 21 drive several bearing plates 23 to rotate intermittently. When the bearing plate 23 rotates to one end of the conveyor belt 21 and stops, the external feeding component places the bearing body 43 to be tested on the upper end of the bearing plate 23. Then the conveyor belt 21 continues to drive the bearing body 43 to move.

[0030] Synchronous belts 44 are fixedly provided on the inner side of the transmission belt 21. Synchronous pulleys are provided at both ends of the synchronous belt 44. The synchronous pulleys are installed in the mounting groove in the middle of the drive roller and the transmission roller. When in use, this facilitates the increase of the transmission accuracy of the transmission belt 21.

[0031] The drive assembly includes a first motor 16 and a first electric cylinder 18. A fixing rod is mounted on the upper end of each detection component 11. The fixing rod is fixed to the bottom end of a sliding frame 12. The sliding frame 12 is slidably mounted on the mounting rod. A stop plate 13 is slidably mounted inside the sliding frame 12. The stop plate 13 is rotatably mounted on one end of a screw. The screw is located in a threaded hole at the upper end of the sliding frame 12. The mounting rod is fixed to a mounting shaft. An external spline shaft 14 is fixed to one end of the mounting shaft. An internal spline shaft 15 is sleeved on the external spline shaft 14. A rotating plate 17 is rotatably mounted on the internal spline shaft 15. The rotating plate 17 is fixed to the output end of the first electric cylinder 18. The first electric cylinder 18 is fixed to the upper inner side of the top frame 19. The external spline shaft 14 is fixed to the output end of the first motor 16. The first motor 16 is fixed to the upper inner side of the top frame 19. The distance between the two first motors 16 is equal to the distance between two adjacent bearings. The plates 23 are spaced equally. The first motor 16 and the first electric cylinder 18 are electrically connected to the control component 42, which is fixedly mounted on the mounting box 20. In use, when the conveyor belt 21 moves the bearing body 43 to below the outermost detection component 11 and stops, the output end of the first electric cylinder 18 moves the rotating plate 17, which in turn moves the inner spline shaft 15. The inner spline shaft 15 moves the detection component 11 downward at a constant speed, while the output end of the first motor 16 moves the outer spline shaft 14 at a constant speed, causing the detection component 11 to rotate around the mounting shaft axis. This allows the detection component 11 to detect the inner diameter of the bearing body 43. Similarly, after the bearing body 43 moves to below another detection component 11, the other detection component 11 can detect the outer diameter of the bearing body 43. It is worth noting that the detection component 11 in this application uses existing components and can be selected according to actual use. This will not be elaborated further here.

[0032] The first clamping mechanism includes first clamping blocks 24, four of which are arranged in a circular array. A first fixing plate is fixedly mounted on the bottom end of each first clamping block 24. A first limiting groove is provided at the upper end of the bearing plate 23 corresponding to the position of the first fixing plate. A first mounting groove is symmetrically provided on one side of each first limiting groove. A first return spring 25 is provided in each first mounting groove, and the other end of each first return spring 25 is fixedly connected to the first fixing plate. A first connecting rod 26 is hinged to the bottom end of each first fixing plate, and the other end of each first connecting rod 26 is hinged to a mounting ring 27. A plurality of first guide rods 28 are arrayed on the upper end of the mounting ring 27. The first guide rods 28 are slidably disposed within sliding holes at the bottom end of the bearing plate 23. Fixing frames 2 are symmetrically provided on the mounting ring 27. 9. Each of the inner sides of the conveyor belt 21 is provided with a first guide plate 30. The first guide plate 30 is located below a detection component 11. One end of the first guide plate 30 is inclined. The two first guide plates 30 are respectively aligned with one end of the two fixed frames 29. The first guide plates 30 are fixed inside the mounting box 20. In use, before the conveyor belt 21 moves the bearing plate 23 to below the inner diameter detection component 11, the fixed frame 29 is in close contact with the inclined end of the first guide plate 30, so that the first guide plate 30 guides the fixed frame 29. The fixed frame 29 drives the mounting ring 27 to slide. The mounting ring 27 drives the first fixed plate to slide through the first connecting rod 26. The first fixed plate drives the first clamping block 24 to move, so that the several first clamping blocks 24 position and clamp the bearing body 43.

[0033] The second clamping mechanism includes two clamping blocks 31, four of which are arranged in a circular array. Each clamping block 31 has a second fixing plate fixed to its bottom end. The upper end of the bearing plate 23 has a second limiting groove corresponding to the position of the second fixing plate. A second mounting groove is symmetrically provided on one side of each limiting groove. A second return spring 32 is provided in each mounting groove, and the other end of each return spring 32 is fixedly connected to the second fixing plate. A second connecting rod 33 is hinged to the bottom end of each fixing plate, and the other end of each connecting rod 33 is hinged to a hinge frame 34. A second guide rod 36 is fixedly provided at the upper end of the hinge frame 34, and the second guide rod 36 slides within a sliding hole at the bottom end of the bearing plate 23. A top rod 35 is fixedly provided at the bottom end of the hinge frame 34, and one end of the top rod 35 has a ball bearing. The conveyor belt 21 contains... The bearing body 43 is equipped with a second guide plate 37, which is located below another detection component 11. The two ends of the second guide plate 37 are inclined and aligned with the top rod 35. The second guide plate 37 is fixedly installed inside the mounting box 20. In use, after the outer diameter of the bearing body 43 is detected, before the conveyor belt 21 moves the bearing body 43 to below the outer diameter detection component 11, one end of the top rod 35 is in close contact with the inclined end of the second guide plate 37. The second guide plate 37 guides one end of the top rod 35, and the top rod 35 pushes the hinge frame 34 to move. The hinge frame 34 drives the second fixed plate to slide through the second connecting rod 33. The second fixed plate drives the second clamping block 31 to move, so that several second clamping blocks 31 clamp and fix the inner ring of the bearing body 43. Then, another detection component 11 detects the outer diameter of the bearing body 43.

[0034] The bearing plate 23 is symmetrically provided with mounting columns at both ends, and a support column 38 is rotatably provided at one end of each mounting column. The mounting box 20 is provided with a support plate 39 at the position corresponding to the support column 38. The support plate 39 is aligned with the positions of the support column 38 at the upper and lower ends of the conveyor belt 21, respectively, so as to facilitate the support of the bearing plate 23 during use.

[0035] Example 2

[0036] The difference from Embodiment 1 is that: two second electric cylinders 41 are fixedly provided on the upper inner side of the top frame 19. Each of the output ends of the second electric cylinders 41 is provided with a marking component 40. The working ends of the two marking components 40 are respectively aligned with the inner ring and outer ring of the bearing body 43. In use, when the two detection components 11 detect a defective product when detecting the outer or inner diameter, the product moves to below the second electric cylinder 41, and the corresponding output end of the second electric cylinder 41 drives the marking component 40 to move, and the marking component 40 marks the outer or inner ring.

[0037] The above embodiment discloses an air conditioner compressor bearing inner and outer diameter detection device. When the inner and outer diameters of the bearing body 43 need to be detected, the second motor 22 drives the transmission belt 21 to rotate. The two transmission belts 21 drive several bearing plates 23 to rotate intermittently. When the bearing plates 23 rotate to one end of the transmission belt 21 and stop, the external feeding component places the bearing body 43 to be detected on the upper end of the bearing plate 23. Then, the transmission belt 21 continues to move the bearing body 43. Before the transmission belt 21 moves the bearing plate 23 below the inner diameter detection component 11, the fixing frame 29 is in close contact with the inclined end of the first guide plate 30, so that the first guide plate 30 guides the fixing frame 29. The fixing frame 29 drives the mounting ring 27 to slide. The mounting ring 27 drives the first fixing plate to slide via the first connecting rod 26. The first fixing plate drives the first clamping block 24 to move, so that several first clamping blocks 24 position and clamp the bearing body 43. After the bearing body 43 moves below the detection component 11, the first motor 22 drives the bearing body 43 to rotate intermittently. The output end of the cylinder 18 drives the rotating plate 17 to move, the rotating plate 17 drives the inner spline shaft 15 to move, the inner spline shaft 15 drives the detection component 11 to descend at a constant speed, and at the same time the output end of the first motor 16 drives the outer spline shaft 14 to rotate at a constant speed, so that the detection component 11 rotates around the mounting shaft axis, so that the detection component 11 detects the inner diameter of the bearing body 43. After the outer diameter of the bearing body 43 is detected, before the conveyor belt 21 moves the bearing body 43 to below the outer diameter detection component 11, one end of the push rod 35 is in close contact with the inclined end of the second guide plate 37. The second guide plate 37 guides one end of the push rod 35, and the push rod 35 pushes the hinge frame 34 to move. The hinge frame 34 drives the second fixed plate to slide through the second connecting rod 33. The second fixed plate drives the second clamping block 31 to move, so that several second clamping blocks 31 clamp and fix the inner ring of the bearing body 43. Similarly, after the bearing body 43 moves to below another detection component 11, the other detection component 11 can detect the outer diameter of the bearing body 43.

[0038] 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.
