[0002] When installing bearing rings onto the mounting shaft, a pressing device is required. The main principle of the pressing device is to perform the pressing action by extending or retracting an electric cylinder or hydraulic cylinder.
[0003] When the electric cylinder used for extrusion is damaged during the use of the existing equipment, it needs to be repaired or replaced before it can continue to be used. It is not suitable for emergency use and has poor flexibility. After a period of use, the existing equipment will accumulate dust on the base due to the large amount of dust in the workshop. It requires staff to clean it regularly. However, the cleaning efficiency is affected by the obstruction of the placement seat. Utility Model Content

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.
[0024] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 As shown: This utility model provides a thrust ball bearing ring pressing device, including a base 1. The base 1 is placed on a workbench, and two cylindrical insertion holes 101 are opened on the left and right sides of the top surface of the base 1. A limiting component 3 is installed on the top surface of the base 1. The limiting component 3 consists of a second connecting block 301, an insertion rod 302, a second guide rod 303, a positioning block 304, and a second electric cylinder 305. Two insertion rods 302 are inserted into each insertion hole 101. The upper end of the two insertion rods 302 on the left is welded to one of the second connecting blocks 301, and the upper end of the two insertion rods 302 on the right is welded to the top surface of the other second connecting block 301. When cleaning the top surface of the base 1, the two second connecting blocks 301 can be directly pulled out from the base 1, which facilitates the cleaning of the top surface of the base 1.
[0025] Both plug rods 302 are cylindrical rod-shaped structures, and the lower end of both plug rods 302 is an arc-shaped structure, which makes it more convenient and faster to plug the plug rods 302 into the plug hole 101.
[0026] Each second connecting block 301 has two second guide rods 303 sliding on it. The right end of the two second guide rods 303 on the left is welded to a positioning block 304, and the right end of the two second guide rods 303 on the right is welded to another positioning block 304.
[0027] Each second connecting block 301 has a second electric cylinder 305 welded to its inner side. The extended ends of the two second electric cylinders 305 are respectively fixed to two positioning blocks 304. Each positioning block 304 has a V-shaped clamping groove. The two clamping grooves hold the placement seat 4. The bottom surface of the placement seat 4 contacts the top surface of the base 1. When installing the placement seat 4, the placement seat 4 is placed between the two positioning blocks 304. The two second electric cylinders 305 are controlled to extend. The two second electric cylinders 305 push the two positioning blocks 304 to move inward to complete the clamping and fixing of the placement seat 4. When replacing the placement seat 4, the two second electric cylinders 305 are controlled, and then the placement seat 4 can be removed by hand.
[0028] The base 1 is equipped with a pressing assembly 2, which consists of a first guide rod 201, a first connecting block 202, a mounting block 203, a pressing block 204, a threaded rod 205, and a first electric cylinder 206. Four first guide rods 201 are welded to the top surface of the base 1. The upper end of each of the four first guide rods 201 is welded to the first connecting block 202. A mounting block 203 slides on the four first guide rods 201, and a pressing block 204 is fixed to the bottom surface of the mounting block 203.
[0029] The first connecting block 202 is threaded with a threaded rod 205, which can withstand the pressing force during pressing. A first electric cylinder 206 is rotated at one end of the threaded rod 205. The extended end of the first electric cylinder 206 is fixed on the mounting block 203. During pressing, the bearing is placed on the placement seat 4, and the mounting shaft is inserted into the inner ring of the bearing. At this time, the mounting shaft is aligned with the pressing block 204. The first electric cylinder 206 is extended, and the inner ring of the bearing is pressed onto the mounting shaft by the pressing block 204. When the first electric cylinder 206 cannot extend, the threaded rod 205 is rotated by hand. Under the drive of the threaded rod 205, the pressing block 204 moves downward to complete the pressing.
[0030] Example 2: Based on Example 1, a switch box 5 is fixed on the top surface of the base 1. The switch box 5 is electrically connected to an external power supply and electrically connected to the first electric cylinder 206 and the second electric cylinder 305. The switch box 5 is equipped with a switch for controlling the extension and retraction of the first electric cylinder 206 and the second electric cylinder 305. In use, pressing the switch on the switch box 5 can control the extension and retraction of the first electric cylinder 206 and the second electric cylinder 305.
[0031] Working principle: During press fitting, the bearing is placed on the mounting base 4, and the mounting shaft is inserted into the inner ring of the bearing. At this time, the mounting shaft and the press fitting block 204 are aligned. The first electric cylinder 206 is extended, and the inner ring of the bearing is pressed onto the mounting shaft by the pressing block 204. When the first electric cylinder 206 cannot extend, the threaded rod 205 is rotated by hand. Under the drive of the threaded rod 205, the press fitting block 204 moves downward to complete the press fitting. When installing the mounting base 4, the mounting base 4 is placed between the two positioning blocks 304. The two second electric cylinders 305 are extended, and the two second electric cylinders 305 push the two positioning blocks 304 inward to complete the clamping and fixing of the mounting base 4. When replacing the mounting base 4, the two second electric cylinders 305 are controlled, and then the mounting base 4 can be removed by hand. When cleaning the top surface of the base 1, the two second connecting blocks 301 are directly pulled out from the base 1, which makes it convenient to clean the top surface of the base 1.
