Description

Technical Field

[0001] The utility model relates to the technical field of detection tooling, in particular to an oil-impregnated bearing detection tooling. Background Art

[0002] An oil-impregnated bearing, that is, a porous bearing, mainly uses metal powder as the raw material. The oil-impregnated bearing is a sintered body made by powder metallurgy method. It is inherently porous and has technical advantages such as the number, size, shape, and distribution of pores that can be adjusted relatively freely during the manufacturing process; after the oil-impregnated bearing is produced and manufactured, it needs to be detected, and only after passing the detection can it be sold and used externally.

[0003] The Chinese utility model patent application number is: 202021006192.4, which discloses an oil-impregnated bearing detection tooling. The oil-impregnated bearing detection tooling of the utility model is used to solve the technical problem of inaccurate unqualified rate caused by non-standard and inaccurate detection methods during the detection of existing oil-impregnated bearings.

[0004] However, in the above patent, positioning holes corresponding to the optical axis sections are provided on the base, which is only convenient for accurately positioning oil-impregnated bearings of the same size and including optical axis sections, with low applicability and inconvenient for positioning oil-impregnated bearings without optical axis sections. After placing oil-impregnated bearings of different sizes and without optical axis sections in the accommodating groove, it is not convenient to position and clamp them. Therefore, an oil-impregnated bearing detection tooling needs to be designed. Summary of the Utility Model

[0005] In view of this, the utility model provides an oil-impregnated bearing detection tooling, and the main technical problem to be solved is: the existing equipment is not convenient for positioning and clamping oil-impregnated bearings of various different sizes and without optical axis sections.

[0006] To achieve the above object, the utility model adopts the following technical scheme: an oil-impregnated bearing detection tooling, including a bottom plate, the upper end of the bottom plate is fixedly connected with a workbench and a support frame, the inside of the support frame is fixedly connected with a guide cylinder, the upper end surface of the workbench is provided with a circular hole and three sliding holes, and the three sliding holes are evenly distributed around the circular hole. The circular hole is located directly below the guide cylinder. A positioning rod is slidably connected inside each of the plurality of sliding holes. A position adjusting mechanism is installed between the workbench and the bottom plate, and the position adjusting mechanism is connected to the positioning rod and used to control the positioning rod to move along the sliding hole. A driving mechanism is installed at the lower end of the bottom plate, and the driving mechanism is connected to the position adjusting mechanism and used to provide power for the position adjusting mechanism to operate.

[0007] By adopting the above technical solution, it is convenient to accurately position and clamp oil-impregnated bearings of various different sizes without a light axis section, so that oil-impregnated bearings of various different sizes without a light axis section can be accurately and stably located at the upper end of the workbench and directly below the guide cylinder. Thus, it is convenient to subsequently use a go-no-go gauge to extend into the oil-impregnated bearing along the guide cylinder for inspection work on the oil-impregnated bearing.

[0008] Furthermore, a plurality of support feet are fixedly connected to the lower end of the bottom plate.

[0009] By adopting the above technical solution, the presence of the support feet enables the overall equipment to be stably located on the ground.

[0010] Furthermore, the position adjustment mechanism includes guide rails, sliders, a first gear, a rotating shaft, second gears, fixed shafts, a moving plate, and fixed rods. The rotating shaft is rotatably connected to the inside of the bottom plate, and the circumferential surface of the rotating shaft is fixedly connected with the first gear. Three second gears are rotatably connected to the upper end of the bottom plate, and multiple second gears are all meshed with the first gear. Fixed shafts are fixedly connected to the upper ends of multiple second gears. Three guide rails are fixedly connected to the bottom end of the workbench, and sliders are slidably connected to the inside of the three guide rails. Fixed rods are fixedly connected to the inside of multiple sliders, and multiple fixed rods are respectively fixedly connected to multiple positioning rods. The bottom ends of multiple fixed rods are all fixedly connected with a moving plate. The moving plate is located above the second gear, and a through hole for the fixed shaft to slide is formed on the upper end surface of the moving plate, and the fixed shaft is located in the through hole; the central axis of the fixed shaft is parallel to the central axis of the second gear, and the fixed shaft is located at the edge position above the second gear.

[0011] By adopting the above technical solution, the driving mechanism can drive the rotating shaft to rotate, the rotating shaft drives the first gear to rotate, at this time the second gears rotate accordingly, the second gears drive the fixed shafts to rotate, and with the rotation of the fixed shafts, under the mutual cooperation of the moving plate and the through hole, the fixed rods and the sliders are driven to move along the guide rails, and then the positioning rods are driven to move along the sliding holes. By adjusting the positions of the positioning rods, it is convenient to position and clamp oil-impregnated bearings of different diameters.

[0012] Furthermore, the driving mechanism includes a worm, a worm gear, a bearing seat, and a handle. The rotating shaft penetrates downward through the bottom plate, and the bottom end of the rotating shaft is fixedly connected with the worm gear. The bearing seat is fixedly connected to the lower end of the bottom plate, and the worm is rotatably connected to the inside of the bearing seat. The worm is meshed with the worm gear, and the handle is fixedly connected to the front end of the worm.

[0013] By adopting the above technical solution, rotating the handle drives the worm to rotate, and then drives the worm gear to rotate, and the worm gear drives the rotating shaft to rotate. Therefore, the driving mechanism can provide power for the position adjustment mechanism to operate.

[0014] Further, the lower end of the workbench is fixedly connected to a support platform through a support rod. The support platform is located directly below the circular hole and directly above the first gear.

[0015] By adopting the above technical solution, during operation, the passing end of the go-no-go gauge freely falls into the oil-impregnated bearing along the guide cylinder. After extending out of the oil-impregnated bearing, the presence of the support platform can support the passing end of the go-no-go gauge, preventing the go-no-go gauge from affecting the first gear due to passing downward through the circular hole.

[0016] By virtue of the above technical solution, the oil-impregnated bearing detection tooling of the present utility model has at least the following beneficial effects:

[0017] 1. Compared with the prior art, this oil-impregnated bearing detection tooling can accurately position and clamp and fix various oil-impregnated bearings of different sizes without a smooth shaft section through the mutual cooperation of the driving mechanism and the position adjustment mechanism, enabling the oil-impregnated bearing to be stably located on the workbench and directly below the guide cylinder, so as to facilitate the subsequent stable use of the go-no-go gauge to detect the oil-impregnated bearing.

[0018] 2. Compared with the prior art, this oil-impregnated bearing detection tooling, under the action of the guide cylinder, when detecting the central hole of the oil-impregnated bearing, only needs to insert the go-no-go gauge into the guide cylinder. After releasing the go-no-go gauge, the go-no-go gauge freely falls along the axial direction of the guide cylinder. The tester can judge whether the oil-impregnated bearing is qualified according to the depths of the passing end and the non-passing end of the go-no-go gauge inserted into the oil-impregnated bearing. Compared with the existing manual detection method, the present utility model can avoid the problem of inaccurate detection caused by non-standard operations, and thus the final detection is more accurate.

A driving mechanism is installed at the lower end of the base plate 1, and the driving mechanism is connected to the position adjustment mechanism and is used to provide power for the position adjustment mechanism to operate. During work, it is convenient to accurately position and clamp oil-impregnated bearings of various different sizes without a optical axis section, so that oil-impregnated bearings of various different sizes without a optical axis section can be accurately and stably located on the upper end of the workbench 2 and at the same time directly below the guide tube 4, thereby facilitating the subsequent use of a go-no-go gauge to extend into the oil-impregnated bearing along the guide tube 4 to detect the oil-impregnated bearing. In this way, the practicability and applicability of the overall equipment can be finally improved.

[0026] A plurality of support feet are fixedly connected to the lower end of the base plate 1. During work, the presence of the support feet can make the overall equipment stably located on the ground.

[0027] The position adjusting mechanism includes a guide rail 9, a slider 10, a first gear 15, a rotating shaft 16, a second gear 14, a fixed shaft 13, a moving plate 12 and a fixed rod 11. The rotating shaft 16 is rotatably connected inside the bottom plate 1. The circumferential surface of the rotating shaft 16 is fixedly connected with the first gear 15. Three second gears 14 are rotatably connected to the upper end of the bottom plate 1. Multiple second gears 14 are all meshed with the first gear 15. The upper ends of multiple second gears 14 are all fixedly connected with the fixed shaft 13. Three guide rails 9 are fixedly connected to the bottom end of the workbench 2. Sliders 10 are slidably connected inside the three guide rails 9. Fixed rods 11 are fixedly connected inside multiple sliders 10. Multiple fixed rods 11 are respectively fixedly connected with multiple positioning rods 7. The bottom ends of multiple fixed rods 11 are all fixedly connected with the moving plate 12. The moving plate 12 is located above the second gear 14. A through hole for the fixed shaft 13 to slide is formed on the upper end surface of the moving plate 12, and the fixed shaft 13 is located inside the through hole; the central axis of the fixed shaft 13 is parallel to the central axis of the second gear 14, and the fixed shaft 13 is located at the edge position above the second gear 14. During operation, the driving mechanism can drive the rotating shaft 16 to rotate, the rotating shaft 16 drives the first gear 15 to rotate, at this time the second gear 14 rotates accordingly, the second gear 14 drives the fixed shaft 13 to rotate, as the fixed shaft 13 rotates, under the mutual cooperation of the moving plate 12 and the through hole, the fixed rod 11 and the slider 10 are driven to move along the guide rail 9, and then the positioning rod 7 is driven to move along the sliding hole 6. By adjusting the position of the positioning rod 7, it is convenient to position and clamp oil-impregnated bearings with different diameters.

[0028] The driving mechanism includes a worm 17, a worm gear 20, a bearing seat 18 and a handle 8.

[0029] The lower end of the workbench 2 is fixedly connected with a support platform 19 through a support rod. The support platform 19 is located directly below the circular hole 5 and directly above the first gear 15. During operation, when the through end of the go-no-go gauge freely falls into the oil-impregnated bearing along the guide cylinder and extends out of the oil-impregnated bearing, the existence of the support platform 19 can block the through end of the go-no-go gauge to prevent the go-no-go gauge from affecting the first gear 15 due to passing downward through the circular hole 5.

[0030] Working principle:

[0031] During use, place the oil-impregnated bearing to be detected in the workbench 2. At the same time, the circular hole 5 corresponds to the central hole of the oil-impregnated bearing. Then control the driving mechanism to operate, providing power for the position adjustment mechanism to operate. The position adjustment mechanism drives a plurality of positioning rods 7 to move along the sliding holes 6 towards each other in a square shape, so as to clamp and position the oil-impregnated bearing, making it accurately located directly above the circular hole 5 and directly below the guide cylinder 4. Then insert the go-no-go gauge into the guide cylinder 4. Using the guidance of the guide cylinder 4, insert the go-no-go gauge into the central hole of the oil-impregnated bearing. Among them, the inspector needs to determine whether the oil-impregnated bearing is qualified according to the insertion depths of the go end and no-go end of the go-no-go gauge into the oil-impregnated bearing.
