Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bearing assembly, in particular to a deep groove ball bearing automatic assembly production line and process. BACKGROUND

[0002] The deep groove ball bearing is the most widely used and most representative rolling bearing, and the bearing needs to be assembled in the production process. The existing bearing assembly production line is too long and occupies too much area, and is connected together. Once a fault occurs in the process, the whole production line needs to stop running, resulting in low assembly efficiency.

[0003] The production line process of the deep groove ball bearing is relatively complex. In the process after the assembly of the ball, the ball needs to be greased. In this production line process, the lubricating grease is injected through the grease injection cylinder. However, the core area between the balls cannot be fully penetrated during the injection, resulting in uneven distribution of the grease. This easily causes the grease to accumulate near the injection point, making it difficult to cover the entire bearing internal space. In addition, if the injection continues, the grease not only cannot further penetrate the core area, but also may overflow from the top of the bearing, resulting in insufficient actual grease injection in the bearing and contamination of the top of the bearing.

[0004] After the assembly of the deep groove ball bearing is completed, the bearing directly falls into the storage box. Each time the deep groove ball bearing falls, it collides with each other and is arranged in disorder, resulting in scratches and other defects on the surface of the deep groove ball bearing. After the end, the deep groove ball bearing needs to be arranged.

[0067] A process of a deep groove ball bearing automatic assembly production line, comprising the following steps:

[0068] Step one: through the clamping transfer structure 3, the bearing is transferred at a distance, the front of the bearing is injected, the bearing is reversed, the back of the bearing is injected, the end cover is placed on the back of the bearing, the end cover placed on the back of the bearing is compacted, the bearing is reversed again, the end cover is placed on the front of the bearing, the end cover placed on the front of the bearing is compacted, and the bearing injection operation is completed.

[0069] Step two: the assembled bearing slides from the platform 2 to the support plate 1303, is guided by the guide plate 1304, enters the storage box 1305 in an orderly manner, and is arranged in a row. After a row is full, the feeding electric push rod 1306 drives the push plate 1308 to push the row of bearings to the other side of the storage box 1305.

[0070] As an embodiment, in the above step one assembly process, the grease injection port at the bottom of the grease injection cylinder 406 is inserted between the balls in the bearing, and the bearing is pressed into the housing 19. The clamping plate 22 arranged in the housing 19 clamps the surface of the bearing, and drives the clamped bearing to rotate, so that the grease injected by the grease injection cylinder 406 is evenly distributed in the bearing.

[0071] Step three: when the grease injection port at the bottom of the grease injection cylinder 406 is inserted into the bearing, the annular pipe 417 blocks the rising. After the grease injection is completed, the annular pipe 417 is lowered to reset when the grease injection cylinder 406 moves up, so as to avoid the bearing moving with the grease injection cylinder 406. The suction head 420 on the annular pipe 417 is reset to one side of the grease injection port at the bottom of the grease injection cylinder 406, and the residual grease in the grease injection port is extracted.

[0072] The working principle of the present application is as follows:

[0073] In use, the feeding structure 12 sequentially feeds the bearings to the platform 2, and the clamping transfer structure 3 sequentially transfers the bearings to the corresponding stations of the front grease injection structure 4, the first reversing structure 5, the back grease injection structure 6, the back cover placing structure 7, the back cover pressing structure 8, the second reversing structure 9, the front cover placing structure 10, and the front cover pressing structure 11. After the grease injection and cover pressing are completed, the clamping transfer structure 3 feeds the bearings to the discharging structure 13 for collection, thereby completing the automatic assembly production line of the bearings.

[0074] When the bearings are in the grease injection stations of the front grease injection structure 4 and the back grease injection structure 6, the grease injection cylinder 406 is lowered to press the bearing into the housing 19. The clamping plate 22 in the housing 19 clamps and fixes the bearing. During the grease injection process, the outer ring of the clamped bearing is driven to rotate, so as to promote the injected grease to evenly fill the internal space of the bearing, thereby improving the penetration effect of the grease between the raceway and the balls, and reducing the overflow of the grease at the top of the bearing.

[0075] When the grease injection cylinder 406 is lowered for grease injection, the annular tube 417 is blocked by the top of the bearing and remains in place. After the grease injection is completed, the grease injection cylinder 406 is raised, and the annular tube 417 continuously presses the bearing during the resetting process to prevent the bearing from moving upward with the grease injection cylinder 406. After the annular tube 417 is reset, the suction head 420 is moved close to the grease injection port of the grease injection cylinder 406 under the action of the compression spring 421, and the telescopic tube 419 is synchronously expanded to achieve efficient extraction of residual grease in the grease injection port.

[0076] The completed bearing is slid off the platform 2 to the support plate 1303, guided by the guide plate 1304 to enter the storage box 1305 in an orderly manner, and arranged in a row. After a row is full, the feeding electric push rod 1306 drives the push plate 1308 to push the row of bearings to the other side of the box, and then the push plate 1308 is reset to continue pushing the next row until the storage box 1305 is full.

[0077] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; 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.
