[0002] The taper pin plays a role of fixing and blocking in the slewing bearing. If the bearing needs to be disassembled, the taper pin must be disassembled first.

[0003] At present, four-point contact ball slewing bearings and cross roller bearings generally have two types of single-row raceways and double-row raceways, and even three-row raceways. Each set of bearings has one to three taper pins. The traditional taper pin removal (or installation) is to place a cylindrical pin on the small end (or large end) of the taper pin, and then use a copper rod to strongly knock it down (or install it). The removal (installation) process is also very difficult, with extremely low safety, time-consuming and labor-intensive. Therefore, the present application proposes a taper pin installation and removal device for slewing bearing production to solve such problems. Summary of the invention

[0015] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Figure 2 All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0016] See also Figure 1-3 The present application provides a technical solution for a tapered pin installation and disassembly device for the production of slewing bearings: a tapered pin installation and disassembly device for the production of slewing bearings, comprising a base plate 1, at least three support roller groups 2 are arranged on the upper surface of the base plate 1, and a slewing bearing 3 is supported on the support roller group 2.

[0017] Specifically, there are three supporting roller groups 2 , which are evenly distributed on the bottom plate 1 in a circumferential manner.

[0018] More specifically, the support roller group 2 is mainly composed of a support roller and two mounting plates, between which the support roller is rotatably connected, and the mounting plates are fixed to the bottom plate 1 by bolts.

[0019] In this arrangement, the turntable bearing 3 is supported by the support roller group 2, and the turntable bearing 3 can also be assisted to rotate, thereby facilitating the installation or removal of the taper pin on the push rod on the cylinder 9.

[0020] It also includes a movable plate 4. The upper surface of the bottom plate 1 is connected to the movable plate 4 through a movable wheel 15. A column 6 is arranged on the upper surface of the movable plate 4. The upper surface of the column 6 is fixedly connected to the top plate 8. A cylinder 9 is arranged on the upper surface of the top plate 8. The telescopic end of the cylinder 9 passes through the top plate 8 and is connected to the top rod. A fixed component is sleeved on the column 6.

[0021] Specifically, the column 6 can support the top plate 8 and guide the fixed component. Through the setting of the fixed component, the movable plate 4, the column 6 and the cylinder 9 can be fixed on the turntable bearing 3, thereby avoiding the overall shaking of the cylinder 9 during operation and improving the quality of the installation and removal of the taper pin. Through the setting of the moving wheel 15 and the cylinder 9, the fixed component, the cylinder 9 and the movable plate 4 can be moved to a suitable position, thereby improving the practicability of the device and reducing the labor intensity of workers.

[0022] Furthermore, the fixed assembly is mainly composed of a fixed plate 10, a moving block 11, a handwheel 12 and a screw rod 13. The moving block 11 is sleeved on the column 6, and the moving block 11 is connected to the screw rod 13 through a screw nut. The bottom end of the screw rod 13 is rotatably connected to the moving plate 4, and the top end of the screw rod 13 is fixedly connected to the handwheel 12. Two fixed plates 10 are provided at one end of the moving block 11.

[0029] During use: place the slewing bearing 3 on the supporting roller group 2, then push the movable plate 4 to the bottom of the slewing bearing 3, and align the telescopic end of the cylinder 9 with the tapered pin hole, then turn the hand wheel 12 to rotate the screw rod 13, and then the screw rod 13 drives the movable block 11 and the fixed plate 10 to move toward the slewing bearing 3, and make the second rubber pad at the bottom of the fixed plate 10 contact with the slewing bearing 3, then continue to turn the hand wheel 12, so that the movable plate 4 moves toward the slewing bearing 3 as the hand wheel 12 rotates, and cooperates with the fixed plate 10 to fix the cylinder 9 above the slewing bearing 3, then start the cylinder 9, and the taper pin is installed or removed by the push rod at the telescopic end of the cylinder 9.
