Description

Technical Field

[0001] The utility model relates to the technical field of slewing bearing production, in particular to a measuring device for slewing bearing production. Background Technique

[0002] A slewing bearing is a new type of mechanical component, which consists of a hollow ring, a gear ring and rolling elements, etc. A slewing bearing is a large bearing that can bear comprehensive loads and can simultaneously bear large axial, radial loads and tipping moments. During the production process of a slewing bearing, data such as end runout and tooth runout need to be measured to ensure its subsequent use. Among them, end runout refers to the axial displacement caused by axial vibration during the operation of the bearing, and tooth runout refers to the unstable instantaneous clearance generated between the tooth surfaces of the gear. Larger end runout and tooth runout will affect the use effect of the slewing bearing.

[0003] At present, when measuring the end runout and tooth runout of a slewing bearing, a gear radial runout measuring instrument is usually used. When using this measuring instrument, the staff needs to rotate the gear ring. For a slewing bearing with a larger size, the staff usually needs to use a crowbar to cooperate with the gear ring and rotate the gear ring. This process is quite laborious and easily causes the staff to feel tired. In addition, the volume of the gear radial runout measuring instrument is small. After it is stored idle, it is inconvenient for the staff to quickly find and use the gear radial runout measuring instrument, thus affecting the efficiency of the measuring operation.

A positioning mechanism 11 is provided on the top of the column 10. A chute 12 is formed on the surface of the positioning mechanism 11. A slider 13 is slidably connected to the inner wall of the chute 12. The number of sliders 13 is two. The surfaces of the two sliders 13 are respectively fixedly connected to a first bent plate 14 and a second bent plate 15. Measuring instrument bodies 16 are installed on the surface of the first bent plate 14 and the top of the second bent plate 15. The measuring instrument bodies 16 can measure the end runout and tooth runout of the slewing bearing body 20. The slewing bearing body 20 includes a hollow ring, a tooth ring sleeved on the surface of the hollow ring, and rolling elements provided in the hollow ring and the tooth ring. Grooves and cylindrical grooves are respectively formed on the tops of the hollow ring and the tooth ring. This is a mature existing technology and will not be elaborated here. A screw rod 18 is fixedly connected to the surface of the slider 13. A collar 19 is threadedly sleeved on the surface of the screw rod 18. The surface of the collar 19 contacts the surface of the chute 12. By the cooperation of the screw rod 18 and the collar 19, the staff can increase the stability of the slider 13.

[0024] The connecting mechanism 6 includes a hollow cylinder 61, a disc 62, a compression spring 63, and a connecting rod 64. The hollow cylinder 61 is fixedly connected to one end of the guide rod 5. The surface of the disc 62 is slidably connected to the inner wall of the hollow cylinder 61. The connecting rod 64 slidably penetrates through the bottom of the hollow cylinder 61 and is fixedly connected to the bottom of the disc 62. The compression spring 63 is arranged inside the hollow cylinder 61. The two ends of the compression spring 63 are respectively fixedly connected to the top of the disc 62 and the top of the inner wall of the hollow cylinder 61. When the connecting rod 64 is in use, it can cooperate with the cylindrical groove on the top of the slewing bearing body 20 to limit the relative position between the connecting mechanism 6 and the slewing bearing body 20, so that the connecting mechanism 6 can drive the slewing bearing body 20 to rotate when rotating along with the guide rod 5.

[0025] The driving mechanism 8 includes a motor 81, a driving shaft 82 and a gear disc 83. The motor 81 is fixedly connected to the top of the U-shaped plate 7.

The column 10 is fixedly connected to the top of the lifting plate 93. When the staff starts the electric push rod 92, the column 10 can be lifted and moved through the lifting plate 93, so that the staff can place the slewing bearing body 20 at the bottom of the inner surface of the outer frame 1. The bottom of the lifting plate 93 contacts with the bottom of the inner surface of the outer frame 1.

[0027] The positioning mechanism 11 includes a cross plate 111, a positioning rod 112 and a limiting ring 113. The cross plate 111 is fixedly connected to the top of the column 10. The chute 12 is opened on the surface of the cross plate 111. The positioning rod 112 slides through the top of the cross plate 111. The limiting ring 113 is fixedly sleeved on the surface of the positioning rod 112. When the staff pulls the positioning rod 112, the limiting ring 113 can be lifted. The surface of the positioning rod 112 can contact with the inner wall of the groove opened at the top of the slewing bearing body 20. During this process, the limiting ring 113 can limit the moving range of the positioning rod 112. The positions of the positioning mechanism 11 and the slewing bearing body 20 can be limited through the cooperation of the positioning rod 112 and the groove.

[0028] The top and bottom of the slider 13 are both fixedly connected with clamping plates 17. The surface of the clamping plates 17 contacts with the inner wall of the chute 12. The setting of the clamping plates 17 can increase the stability of the slider 13 during movement.

[0029] Working principle: The staff places the slewing support body 20 at the bottom of the inner surface of the outer frame 1, and then the staff can make the connecting rod 64 cooperate with the cylindrical groove on the top of the slewing support body 20. During this process, the staff can pull the hollow cylinder 61 to adjust the position of the guide rod 5, so that the device can be used with slewing support bodies 20 of different sizes. After that, the staff starts the electric push rod 92, and the lifting plate 93 drives the column 10 to descend. At this time, the staff can adjust the positioning mechanism 11 and the slewing support body 2 by cooperating with the positioning rod 112 and the slot. 0 is controlled to adjust the position of the measuring instrument body 16. Thereafter, the staff can make more precise adjustments to the positions of the two measuring instrument bodies 16 through the cooperation of the screw rod 18 and the collar 19. Finally, the staff starts the motor 81, and the drive shaft 82 drives the gear plate 83 to rotate. The gear plate 83 cooperates with the spur gear 3 to drive the rotating shaft 2 to rotate. The turntable 4 then drives the connecting mechanism 6 to rotate through the guide rod 5, and the gear ring on the surface of the slewing support body 20 rotates accordingly. In this process, the two measuring instrument bodies 16 can respectively measure the end jump and tooth jump of the slewing support body 20.
