Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing equipment, in particular to a rotor bearing installation machine. Background Art

[0002] During the motor core (rotor) molding or motor assembly process, it is indeed necessary to set bearings at both ends of the motor shaft. The bearings are located at both ends of the motor shaft and mainly play a supporting role, fixing the rotor shaft so that it maintains the correct center position in the motor housing, avoiding unnecessary axial and radial movement, and ensuring the stability of the rotor rotation. The rotor bearing installation machine is used to install bearings on the rotor shaft.

[0003] The existing rotor bearing installation machine has certain risks when replacing the lower die seat. When people replace the lower die seat, there is a possibility that they accidentally touch the switch or the equipment fails, causing the cylinder to drive the pressure plate to press down. Since people's hands are under the pressure plate when replacing the lower die seat, once the pressure plate is pressed down when replacing the lower die seat, it will cause irreparable damage to people's hands. Therefore, it is necessary to develop a structure that can quickly limit the pressure plate when replacing the lower die seat, thereby avoiding the situation where the pressure plate is suddenly pressed down and causes harm to the human body. Utility Model Content

[0006] Preferably, a lower die seat for cooperating with an upper die seat to install the rotor bearing is provided on the top of the workbench.

[0007] Preferably, pressure blocks are symmetrically arranged on both sides of the guide plate, and the bottom of the pressure blocks is in contact with the top of the workbench.

[0008] Preferably, guide columns are symmetrically arranged on the top of the workbench, the top ends of the guide columns are connected to the bottom of the top plate, and the guide columns penetrate the pressing plate to guide the movement of the pressing plate.

[0009] The beneficial effects of the utility model are:

[0010] When the utility model is in use, the pressure plate is moved up to the highest position by the cylinder so that there is enough space under the pressure plate for people to replace the lower mold seat, and then the rotating shaft is rotated by the hand wheel, and the threaded sliders at the positive thread and the negative thread on the rotating shaft move towards each other under the cooperation of the guide groove and the guide plate, and the movement of the threaded slider drives the guide plate to move, and the movement of the guide plate drives the card block to enter the card groove, thereby limiting the pressure plate, preventing the cylinder from driving the pressure plate to move downward due to accidental touch or equipment failure, causing damage to people's hands, and improving the safety of the rotor bearing installation machine.

[0016] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0017] like Figures 1 to 4As shown, a rotor bearing installation machine includes a workbench 1, a top plate 2 is arranged above the workbench 1 through a vertical plate, a cylinder 4 is arranged on the top of the top plate 2, the output end of the cylinder 4 passes through the bottom of the top plate 2 and is provided with a pressure plate 5 with an upper die seat at the bottom, and a card slot 14 is arranged on both sides of the pressure plate 5, and a guide groove 7 is symmetrically arranged on the top of the workbench 1. The internal rotation of the workbench 1 is provided with a rotating shaft 8 with a positive thread and a negative thread on the surface, and the external rotation of the workbench 1 is provided with a handwheel 10 for driving the rotating shaft 8 to rotate, and the outer surfaces of the positive thread and the negative thread are threadedly provided with a threaded slider 9, and a guide plate 11 is arranged on the top of the threaded slider 9, and the guide plate 11 is penetrated into the inside of the guide groove 7, and a card block 12 matching the card slot 14 is arranged on one side of the top of the guide plate 11.

[0018] In this embodiment, when in use, the pressure plate 5 is moved up to the highest point by the cylinder 4 so that there is enough space under the pressure plate 5 for people to replace the lower mold base 6, and then the rotating shaft 8 is rotated by the hand wheel 10, and the threaded sliders 9 at the positive thread and the negative thread on the rotating shaft 8 move toward each other under the cooperation of the guide groove 7 and the guide plate 11, and the movement of the threaded slider 9 drives the guide plate 11 to move, and the movement of the guide plate 11 drives the clamping block 12 to enter the clamping groove 14, thereby limiting the pressure plate 5, preventing the cylinder 4 from driving the pressure plate 5 to move downward due to accidental touch or equipment failure, causing damage to people's hands, and improving the safety of the rotor bearing installation machine.

[0019] like Figure 1 As shown, a lower die seat 6 for cooperating with an upper die seat to install the rotor bearing is provided on the top of the workbench 1. The working principles of the upper die seat and the lower die seat 6 are prior art and will not be described in detail here.

[0020] like Figure 4 As shown, pressure blocks 13 are symmetrically arranged on both sides of the guide plate 11, and the bottom of the pressure block 13 is in contact with the top of the workbench 1. The pressure block 13 is used to prevent the pressure plate 5 from applying excessive pressure to the rotating shaft 8 through the guide plate 11, thereby improving the operating stability of the machine body.
