[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Bearings are divided into many categories, and rolling bearings are just one of them. Rolling bearings mainly include three parts: outer ring, inner ring, rolling element, and cage. After the bearing is produced, a bearing cover needs to be installed on the bearing. When installing the bearing cover, the bearing needs to be clamped and fixed by a bearing fixture.

[0026] Combination Figure 1-5 As shown, this embodiment provides a self-flipping bearing fixture, including: a main body module 100 and a flip module 200.

[0027] Among them, the main module 100 includes a base 110, a plurality of support columns 120 fixed at the top of the base 110, a bottom plate 130 fixed at the top of the support columns 120, a guide rail 140 installed at the top of the base 110, a driving member 150 installed on the inner wall of the guide rail 140, a moving seat 160 movably arranged at the top of the guide rail 140, a threaded sleeve 170 fixed at the bottom end of the moving seat 160 and extending into the inner cavity of the guide rail 140, a first bearing 180 symmetrically installed on the inner wall of the moving seat 160, and a transmission rod 190 installed on the inner wall of the first bearing 180 and extending out of the moving seat 160 at both ends.

[0028] The base 110 is used to install other components and maintain the stability of each component. The support column 120 is used to support the bottom plate 130, so that the bottom plate 130 is raised while maintaining the stability of the bottom plate 130. The bottom plate 130 is used to place bearings that need to be processed. The guide rail 140 is fixed to the top of the base 110 by bolts and is used to install the moving seat 160 to maintain the stability of the moving seat 160 when moving.

[0029] A groove is formed at the top of the guide rail 140 , and a placement groove is formed at one side of the guide rail 140 located at the groove. The driving member 150 is installed in the groove to drive the moving seat 160 to move.

[0030] Furthermore, the driving member 150 includes a threaded rod 151 rotatably mounted on the inner wall of the groove and a first motor 152 mounted on the inner wall of the placement groove and with its shaft fixedly connected to the end of the threaded rod 151. The threaded rod 151 is used to rotate and drive the threaded sleeve 170 to move, and the first motor 152 is used to drive the threaded rod 151 to rotate.

[0031] The threaded sleeve 170 is embedded in the groove, and the top end extends out of the groove and is fixedly connected to the bottom end of the movable seat 160, and the threaded rod 151 passes through the threaded sleeve 170 and meshes with the threaded sleeve 170, so that when the threaded rod 151 rotates to drive the threaded sleeve 170 to move, the threaded sleeve 170 can synchronously drive the movable seat 160 to move.

[0032] The movable seat 160 is used to install the flip module 200 and drive the flip module 200 to move. A through hole 161 is opened on the top of the movable seat 160. The first bearing 180 is symmetrically arranged on the inner wall of the through hole 161. The outer ring of the first bearing 180 is fixed to the inner wall of the through hole 161, and the inner ring is fixed to the outer side surface of the transmission rod 190. It is used to install the transmission rod 190 and facilitate the rotation of the transmission rod 190.

[0033] The transmission rod 190 is used to install the flip module 200, and drives the flip module 200 to move while facilitating the flip module 200 to rotate.

[0034] The flip module 200 is used to clamp and fix the bearing, and can drive the bearing to flip, including a lower clamping plate 210 whose end is fixed on one side of the transmission rod 190, an electric telescopic rod 220 symmetrically installed on the outer surface of the lower clamping plate 210 and extending through the lower clamping plate 210, an upper clamping ring 230 fixed on the end wall of the electric telescopic rod 220, a worm gear 240 fixed on the other side of the transmission rod 190, a worm 250 arranged on one side of the worm gear 240 and meshing with the worm gear 240, and a second motor 260 installed on the moving seat 160 and the shaft of which is connected to the worm gear 250.

[0035] The lower clamping plate 210 is used to clamp one side of the bearing. The interior of the lower clamping plate 210 is set as a cavity, which is convenient for the upper clamping ring 230 to shrink into the inner cavity of the lower clamping plate 210. A V-shaped groove 211 is opened on the end of the lower clamping plate 210 close to the upper clamping ring 230. When the bearing contacts the V-shaped groove 211, it will automatically move closer to the middle under the action of the V-shaped groove 211 to achieve self-centering of the bearing. The upper clamping ring 230 is semicircular and is used to clamp the other side of the bearing. It cooperates with the lower clamping plate 210 to clamp and fix the bearing. The electric telescopic rod 220 is used to drive the upper clamping ring 230 to move.

[0036] The worm wheel 240 is fixed to one side of the transmission rod 190 and is used to drive the transmission rod 190 to rotate. The worm 250 and the worm wheel 240 are meshed with each other. The rotation of the worm 250 drives the worm wheel 240 to rotate. The second motor 260 is used to drive the worm 250 to rotate.

[0037] The working principle and use process of the utility model are as follows: when in use, the bearing is placed on the top of the bottom plate 130, and the electric telescopic rod 220 is started, driving the upper clamping ring 230 to approach the lower clamping plate 210. During the process of the upper clamping ring 230 approaching, the V-shaped opening 211 on the lower clamping plate 210 is used to fix and clamp the bearing, and then the bearing cover is installed on the bearing. After completion, the first motor 152 is started, driving the threaded rod 151 to rotate, the threaded rod 151 rotates to drive the threaded sleeve 170 to move, and the threaded sleeve 170 moves to drive the moving seat 160. The moving seat 160 moves and drives the lower clamping plate 210 to move through the transmission rod 190, that is, drives the bearing clamped and fixed between the lower clamping plate 210 and the upper clamping ring 230 to move, and then the second motor 260 drives the worm 250 to rotate, drives the worm gear 240 to rotate, and drives the transmission rod 190 to rotate through the rotation of the worm gear 240, that is, drives the lower clamping plate 210 to rotate and flip, thereby drives the bearing to rotate and flip, and then the driving member 150 drives the moving seat 160 to reset, so that the side of the bearing without the bearing cover installed faces upward, and the bearing cover is installed.
