[0002] The bearings in the motor are mainly used to support and position the rotor to reduce friction loss and ensure the smooth operation of the motor. Therefore, the assembly stability of the bearing on the motor end cover is particularly important. At present, the most common bearing assembly method is riveting, but the existing riveting line is divided into two steps: bearing assembly and riveting. As a result, the riveting line is long and requires more equipment, which not only reduces production efficiency, but also increases the equipment failure rate of the riveting line. Summary of the invention

[0003] The technical problem to be solved by the present invention is: how to simplify the bearing riveting process.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows: A technical solution adopted by the present invention is as follows: A bearing riveting and pressing integrated machine comprises an end cover conveyor belt and a bearing riveting and pressing fixture; a riveting and pressing station is provided on the transmission path of the end cover conveyor belt; The bearing riveting fixture includes a first linear reciprocating device, a riveting head and a bearing grabbing portion; the first linear reciprocating device has a movable end that moves in a vertical direction, the riveting station is located below the first linear reciprocating device, the riveting head is connected to the movable end of the first linear reciprocating device, the bearing grabbing portion is movably arranged on the riveting head in the vertical direction, and the riveting teeth on the riveting head surround the bearing grabbing portion.

[0005] In order to solve the above technical problems, another technical solution adopted by the present invention is: a riveting method, after the bearing is assembled into the motor end cover, the end cover is riveted; the end cover after riveting is subjected to quality inspection.

[0006] The beneficial effects of the present invention are as follows: a bearing riveting fixture with a riveting head and a bearing grabbing part is added. During the bearing riveting process, the bearing is grabbed by the bearing grabbing part, and then the first linear reciprocating device is used to drive the bearing grabbing part to assemble the bearing into the motor end cover located on the riveting station. Since the bearing grabbing part is movably arranged on the riveting head in the vertical direction, when the first linear reciprocating device continues to drive the riveting head close to the motor end cover, the bearing grabbing part will move vertically upward relative to the riveting head, thereby allowing the riveting teeth on the riveting head to smoothly rivet the motor end cover. Finally, the bearing grabbing part releases the bearing, and the first linear reciprocating device drives the riveting head and the bearing grabbing part to reset, thereby completing the assembly and riveting fixation of the bearing on the motor end cover in one process.

[0008] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0009] Please refer to Figures 1 to 3As shown, a bearing riveting machine includes an end cover conveyor belt 1 and a bearing riveting fixture 2; a riveting station is provided on the transmission path of the end cover conveyor belt 1; the bearing riveting fixture 2 includes a first linear reciprocating device 21, a riveting head 22 and a bearing grabbing portion 23; the first linear reciprocating device 21 has a movable end movable in a vertical direction, the riveting station is located below the first linear reciprocating device 21, the riveting head 22 is connected to the movable end of the first linear reciprocating device 21, the bearing grabbing portion 23 is movably arranged on the riveting head 22 in the vertical direction, and riveting teeth 221 are provided on the riveting head 22 around the bearing grabbing portion 23.

[0010] Working principle: A bearing riveting fixture 2 with a riveting head 22 and a bearing grabbing portion 23 is added. During the riveting process of the bearing 9, the bearing grabbing portion 23 is used to grab the bearing 9, and then the first linear reciprocating device 21 is used to drive the bearing grabbing portion 23 to assemble the bearing 9 into the motor end cover located on the riveting station. Since the bearing grabbing portion 23 is movably arranged on the riveting head 22 in the vertical direction, when the first linear reciprocating device 21 continues to drive the riveting head 22 close to the motor end cover, the bearing grabbing portion 23 will move vertically upward relative to the riveting head 22, thereby allowing the riveting teeth 221 on the riveting head 22 to rivet the motor end cover smoothly. Finally, the bearing grabbing portion 23 releases the bearing 9, and the first linear reciprocating device 21 drives the riveting head 22 and the bearing grabbing portion 23 to reset, thereby completing the assembly and riveting fixation of the bearing 9 on the motor end cover in one process.

[0011] It is worth mentioning that please refer to Figure 4 As shown, the bearing grabbing portion 23 is inserted into the inner ring of the bearing 9 to grab the bearing 9. Specifically, a ball screw 231 is provided on the bearing grabbing portion 23, and the steel ball on the ball screw 231 is pressed against the inner ring of the bearing 9, and the spring inside the ball screw 231 applies elastic force to the steel ball, thereby grabbing the bearing 9.

[0012] Please refer to Figure 1 and Figure 2 As shown, further, an end cover fixing assembly 3 is provided on one side of the riveting station, and the end cover fixing assembly 3 includes a second linear reciprocating device 31 and an end cover clamp 32, the second linear reciprocating device 31 has a movable end facing the riveting station, and the end cover clamp 32 is arranged on the movable end of the second linear reciprocating device 31.

[0013] As can be seen from the above description, after the motor end cover moves to the riveting station, the end cover is clamped by the end cover fixture 32, which can not only compensate for the position of the motor end cover in place, but also prevent the motor end cover from being significantly displaced during the process of assembling the bearing 9 or riveting the motor end cover, thereby affecting the assembly of the bearing 9 on the motor end cover. At the same time, the second linear reciprocating device 31 is used to make the end cover fixture 32 approach or move away from the riveting station to ensure the normal transmission of the motor end cover by the end cover conveyor belt 1.

[0014] Please refer to Figure 1 and Figure 2 As shown, further, the above-mentioned bearing riveting machine also includes a bearing transmission component 4 and a third linear reciprocating device 5, the bearing transmission component 4 includes a bearing transmission belt 41, the third linear reciprocating device 5 is arranged on the movable end of the first linear reciprocating device 21, and the bearing riveting fixture 2 is arranged on the movable end of the third linear reciprocating device 5, and the movable end of the third linear reciprocating device 5 reciprocates with the discharge end of the bearing transmission belt 41 and above the riveting station.

[0015] From the above description, it can be seen that the bearing conveyor belt 41 is used to realize automatic loading of the bearing 9, and the third linear reciprocating device 5 is used to realize the reciprocating movement of the bearing grabbing part 23 between the discharge end of the bearing conveyor belt 41 and above the riveting station; the first linear reciprocating device 21 is used to realize the bearing grabbing part 23 grabbing the bearing 9 at the discharge end of the bearing conveyor belt 41, and the first linear reciprocating device 21 is used to realize the bearing grabbing part 23 to assemble the bearing 9 and the motor end cover at the riveting station.

[0016] Please refer to Figure 1 and Figure 2 As shown, further, the bearing transmission component 4 also includes a bearing feeding component 42 located on the feeding end side of the bearing transmission belt 41, and the bearing feeding component 42 includes a bearing filling tube 421, a bearing preparation plate 422, a push plate 423 and a fourth linear reciprocating device 424; the bearing preparation plate 422 is located below the discharge end of the bearing filling tube 421, and the push plate 423 pushes the bearing located on the bearing preparation plate 422 into the bearing transmission belt 41 through the fourth linear reciprocating device 424.

[0017] From the above description, it can be seen that a large number of bearings 9 are loaded by the bearing filling tube 421 and fall one by one onto the bearing preparation plate 422. The fourth linear reciprocating device 424 drives the pushing plate 423 to push the bearings 9 on the bearing preparation plate 422 into the bearing transmission belt 41 in an orderly manner.

[0018] Please refer to Figure 2As shown, further, the bearing transmission component 4 also includes a material presence sensor 43, the detection end of the material presence sensor 43 faces the transmission surface of the bearing transmission belt 41, and the material presence sensor 43 is communicatively connected with the fourth linear reciprocating device 424.

[0019] From the above description, it can be known that the material presence sensor 43 is used to determine the number of bearings 9 remaining on the bearing conveyor belt 41. If the number of bearings 9 remaining on the bearing conveyor belt 41 is insufficient, the material presence sensor 43 will communicate with the fourth linear reciprocating device 424 to drive the push plate 423 to push the bearings 9 on the bearing preparation plate 422 into the bearing conveyor belt 41, so as to replenish the number of bearings 9 on the bearing conveyor belt 41, thereby ensuring the continuity of the production line.

[0021] From the above description, it can be seen that after the bearing 9 and the electronic end cover are assembled, the bearing transmission belt 41 transmits the motor end cover to the riveting inspection station, and then the CCD camera 61 obtains the rivet point image on the motor end cover to determine whether the motor end cover is riveted and qualified.

[0022] Please refer to Figure 5 As shown, further, the visual detector 6 also includes a fill light 62 located between the CCD camera 61 and the riveting inspection station.

[0023] It can be seen from the above description that the fill light 62 is used to ensure the clarity of the image of the rivet points on the motor end cover obtained by the CCD camera 61 .

[0025] From the above description, it can be seen that the assembled motor end cover is transferred to the end cover placement table 71 by using the transfer robot 8, and then the fifth linear reciprocating device 72 is used to drive the height detector 73 to press on the motor end cover to measure the height, so as to determine whether the bearing 9 is effectively assembled into the motor end cover.

[0026] The height detector 73 has a displacement sensor and a pressure sensor. The height of the motor end cover after assembly is measured by the displacement of the displacement sensor, and the pressure sensor is used to measure the pressure of the height detector 73 pressing the motor end cover. When the pressure reaches the set threshold, the fifth linear reciprocating device 72 stops pressing down, and the displacement of the displacement sensor is recorded at this time to measure the height of the motor end cover after assembly.
