[0019] Specifically, please refer to Figures 1 to 3 , Figure 1 The overall structural diagram of the bearing disassembly device applied to the bearing housing provided in the embodiment of the present application is as follows: Figure 2 for Figure 1 A magnified view at point A. Figure 3A schematic diagram of a partial cross-sectional structure at a workbench provided in an embodiment of the present application. The bearing disassembly equipment 100 applied to the bearing housing includes a horizontally arranged support platform 110. The support platform 110 should be sufficiently stable. Usually, the stability of the support platform 110 can be ensured by constructing a two-story factory building and arranging the support platform 110 in the two-story factory building. A workbench 120 is fixed on the top of the support platform 110. The workbench 120 is a position for workers to stand and operate. The workers need to hold a special unhooking device to drag the bearing to be disassembled on the conveying device 130 into the limiting groove 123 on the workbench 120. A hydraulic cylinder 121a is fixed to the top of the workbench 120 through a frame beam 121. The hydraulic cylinder 121a is used to squeeze the bearing after being stretched, so that the inner cylinder and the outer cylinder of the bearing are separated. An annular limiting groove 123 is provided at the center of the workbench 120. The limiting groove 123 is used to accommodate the bearing to be disassembled. The bearing is dragged into the limiting groove 123 by the worker and further adjusted so that the outer cylinder of the support is placed in the limiting groove 123, while the inner cylinder is suspended. A pressure head 122 matching the limiting groove 123 is provided at the bottom end of the hydraulic cylinder 121a. The pressure head 122 will abut against the inner cylinder of the bearing to be disassembled in the limiting groove 123 after the hydraulic cylinder 121a is pressed down. The pressure head 122 is further pressed down, and the inner cylinder of the bearing is separated from the outer cylinder under the pressure of the pressure head 122, and the balls are dispersed in the limiting groove 123. Then the operator uses the unhooking again to hook out the separated inner cylinder and outer cylinder respectively and drag them to the conveying device 130. A conveying device 130 is provided on the top of the support platform 110, which is located on one side of the workbench 120. The conveying device 130 is used to transport the bearing to be disassembled to the workbench 120, and to transport the inner and outer cylinders of the disassembled bearing away from the workbench 120. A bead discharge tube 124 is provided at the bottom of the limiting groove 123. When the inner and outer cylinders that have been disassembled in the limiting groove 123 are removed in sequence by the operator, the remaining bearing balls will roll down in the limiting groove 123 to the bead discharge tube 124 at the bottom thereof. A guide platform 125 is provided at the bottom of the bead discharge tube 124, and the bearing balls further enter the guide platform 125 from the bead discharge tube 124. The end of the guide platform 125 away from the bead discharge tube 124 is tilted downward, and the guide platform 125 is provided with a plurality of discharge holes 125a in sequence along the axial direction of the guide platform 125. Under the influence of its own gravity, the bearing balls will continue to roll downward in the guide platform 125 and finally enter the discharge hole 125a. The diameter of the material discharge holes 125a increases in sequence along the downwardly inclined direction of the guide platform 125. The purpose of such arrangement is to allow bearing beads of different diameters to enter different guide platforms 125 according to their diameters, thereby conveniently completing classification. The bottoms of the plurality of material discharge holes 125a are all connected to guide tubes 126, which guide bearing beads of different diameters to different positions for storage.
[0020] As can be seen from the above, in the embodiment of the present application, by setting a workbench 120 and a conveying device 130, the conveying device 130 is located on one side of the workbench 120, so that the operator standing on the workbench 120 can drag the bearing to be disassembled on the conveying device 130 into the workbench 120 or drag the inner cylinder and outer cylinder of the bearing that have been disassembled back onto the conveying device 130. In the present application, the outer cylinder of the bearing to be disassembled is supported by setting a limit groove 123, and the hydraulic cylinder 121a and the pressure head 122 are set, so that the hydraulic cylinder 121a drives the pressure head 122 to press down, and the pressure head 122 can separate the bearing by squeezing the inner cylinder of the bearing. The present application also sets a bead discharge tube 124, a guide platform 125 and a feed hole 125a. When the bearing is disassembled, the bearing balls will be drained and stored through the bead discharge tube 124 and the guide platform 125 in turn, thereby greatly saving labor costs. The diameters of the discharge holes 125a on the guide platform 125 are gradually increased, so that the bearing balls in the disassembled bearing can be classified according to the diameters, which is convenient for subsequent classification and storage.
[0021] In some embodiments, the pressing head 122 includes a first extrusion platform 122a, a second extrusion platform 122b and a third extrusion platform 122c connected in sequence from top to bottom. The first extrusion platform 122a, the second extrusion platform 122b and the third extrusion platform 122c are all disc-shaped and coaxially arranged. Correspondingly, the limiting groove 123 includes a first platform 123a, a second platform 123b and a third platform 123c corresponding to the first extrusion platform 122a, the second extrusion platform 122b and the third extrusion platform 122c, respectively. In the embodiment of the present application, through the above settings, the sizes of the first extrusion platform 122a, the second extrusion platform 122b and the third extrusion platform 122c and the first platform 123a, the second platform 123b and the third platform 123c can be set according to the actual size of the bearing, wherein the first platform 123a, the second platform 123b and the third platform 123c correspond to the outer cylinder diameters of different bearings, and the first extrusion platform 122a, the second extrusion platform 122b and the third extrusion platform 122c correspond to the inner cylinder diameters of different bearings. Thus, the present application can disassemble bearings with multiple different apertures, thereby broadening the application scenarios of the present application.
[0022] In some embodiments, the surfaces of the second platform 123b and the third platform 123c are tilted downward toward the central axis thereof. In the embodiment of the present application, through the above arrangement, when the bearing ball falls on the surface of the second platform 123b or the third platform 123c, since the surface is tilted downward, the bearing ball will roll into the bead discharge tube 124 under the action of gravity, thereby preventing the bearing ball from being retained in the limiting groove 123.
[0023] In some embodiments, a plurality of support columns 140 are disposed at the bottom of the support platform 110, and a limiting mesh plate 141 is commonly connected between the plurality of support columns 140, and one end of the guide tube 126 away from the discharge hole 125a is fixed on the limiting mesh plate 141. In the embodiment of the present application, through the above-mentioned configuration, the limiting mesh plate 141 is used to limit and fix the bottom end of the guide tube 126, and the trolley for receiving the bearing beads can be placed at the bottom of each guide tube 126, respectively, so that the bearing beads that have slipped out of the guide tube 126 can be received.
[0024] In some embodiments, an infrared emitter 126a and an infrared receiving board 126b are provided at the bottom end of the guide tube 126, and the infrared emitter 126a is arranged facing the infrared receiving board 126b, and the infrared emitter 126a and the infrared receiving board are both electrically connected to a PLC control box. In the embodiment of the present application, through the above-mentioned setting, under normal working conditions, the rays emitted by the infrared generator are received by the infrared receiving board 126b, and when there are bearing balls rolling down, the bearing balls will block the propagation path of the infrared rays, so that the infrared receiving board 126b will not be able to receive the infrared rays generated by the infrared emitter at this time, and then through the above-mentioned principle, the PLC control box records the disconnection of the infrared rays between the infrared emitter 126a and the infrared receiving board 126b, and the number of bearing balls rolling down can be counted here.
[0025] In some embodiments, a switch 121b is provided on the frame beam 121, and the switch 121b is electrically connected to the pump station of the hydraulic cylinder 121a. In the embodiment of the present application, through the above-mentioned setting, the switch 121b is used to control the lifting and lowering of the hydraulic cylinder 121a, and when the operator needs to press the switch 121b, he must move to the frame beam 121. At this time, the operator and the hydraulic cylinder 121a are at a safe distance, thereby avoiding safety problems caused by accidental touch.
[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application is described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be included in the scope of the claims and specification of the present application. In particular, as long as there is no structural conflict, the various technical features mentioned in the embodiments can be combined in any way.
