Description

Technical Field

[0001] The utility model relates to the technical field of automatic assembly, in particular to a snap ring feeding mechanism. Background Technique

[0002] New energy vehicles are necessarily equipped with permanent magnet synchronous motors or asynchronous motors. Under the background of the increasing market demand for automotive electric motors, the assembly production of electric motors also needs to improve efficiency. Among them, the motor housing is composed of multiple parts. In the shaft housing part, a snap ring needs to be arranged outside the shaft sleeve that is clamped with the main shaft rotor part. Refer to Figure 1 of the attached drawings of the specification. In order to install a snap ring into the annular groove outside the shaft sleeve, we need to specially design an automatic snap ring feeding device to cooperate with the automatic assembly line to quickly press the snap ring into the annular groove to improve the automatic assembly efficiency of the assembly line type electric motor and increase the production capacity. Content of the Utility Model

[0003] The purpose of the utility model is to provide an automatic snap ring feeding device, and help to open the snap ring to help the production line achieve automatic assembly, improve the automatic assembly efficiency of the assembly line type electric motor, and increase the production capacity.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] A snap ring feeding mechanism includes a support frame, a snap ring frame, a limit slideway for controlling the stable feeding of the snap ring, a front push feeding component, a top support component, and a grasping and feeding component.

[0006] The snap ring frame is cylindrical. All snap rings are sleeved and stacked from the upper end of the snap ring frame, and the openings of the snap rings are all limited to one direction, so that all snap rings are neatly stacked. The lowermost end of the snap ring frame is suspended, and the distance from the limit slideway is maintained at a gap of the thickness of one snap ring, so that a single snap ring can be pushed and fed in the gap.

[0007] The limit slideway includes a feeding platform, limit plates on the left and right sides, and an upper cover plate. The distance between the limit plates on the left and right sides is greater than the diameter of the snap ring, and the moving direction of the snap ring pushed is limited. The upper cover is positioned above the limit plates to limit that the snap ring does not jump and fall off when being pushed and fed.

[0008] The front push feeding component includes a front push cylinder and a feeding push block. The top push rod of the front push cylinder drives the feeding push block to move back and forth in a straight line direction between the limit plates on the left and right sides. The front end of the feeding push block is provided with a profiling contour of the snap ring, so as to pre-position the snap ring before pushing it forward.

[0009] The top support and lifting component includes a top support cylinder, a top support fixing block, and a top support separating block. The top push rod of the top support cylinder drives the top support fixing block to move vertically up and down. The top support fixing block is detachably connected to the top support separating block. The upper end of the top support separating block is tapered to lift the inner ring of the circlip, hold the posture after positioning and lifting the circlip, and the gripping and feeding component grabs the top support separating block to feed the circlip to the assembly line.

[0010] Further, the gripping and feeding component includes a horizontal telescopic cylinder, a gripping cylinder, and a clamping arm. The gripping cylinder is driven by the horizontal telescopic cylinder to achieve horizontal sliding, and the clamping arm is driven by the gripping cylinder to achieve a clamping action and clamp the top support separating block.

[0011] Further, a positioning hole is provided on the lower end surface of the top support separating block, and the positioning hole is sleeved and matched with a positioning pin provided on the upper end surface of the top support fixing block. After the clamping arm clamps the top support separating block, the top support cylinder drives the top support fixing block to move downwards to avoid the horizontal displacement space of the top support separating block.

[0012] Further, after the top support separating block is moved to above the bushing of the circlip to be installed, it is matched with the upper shaft hole of the bushing, and the stamping equipment on the assembly line pushes the circlip downwards. The circlip is expanded while being pushed until it is pushed away from the top support separating block and clamped in the annular groove of the bushing.

[0013] Further, a position sensor is provided on one side of the connection between the top support separating block and the top support fixing block to monitor the separation state of the two.

[0014] Compared with the prior art, the utility model adopts the above technical solutions and has the following technical effects:

[0015] The circlip feeding mechanism pre-feeds a batch of circlips to be installed by stacking them layer by layer on the circlip rack, and the lowermost single circlip is limited and fed by the limit slideway, and is stably fed forward by the front pushing and feeding component, and then the top support and lifting component lifts the circlip to be installed. In particular, by using the tapered structure of the detachable top support separating block, it can cooperate with the stamping equipment on the assembly line to expand while being pushed until it is pushed away from the top support separating block and clamped in the annular groove of the bushing, which is practical and convenient.

The lowermost end of the circlip holder 6 is suspended, and the distance from the limit slideway is maintained at a gap of the thickness of one circlip 5, so that a single circlip 5 can be pushed and fed within the gap.

[0024] Refer to Figure 4 , the limit slideway includes a feeding platform 14, limit plates 16 on both the left and right sides, and an upper cover plate 20. The distance between the limit plates 16 on both the left and right sides is greater than the diameter of the circlip 5, and the moving direction of the circlip 5 being pushed is limited. The upper cover plate 20 is positioned above the limit plates 16 to limit the circlip 5 from jumping off and falling off when being pushed and fed.

[0025] Refer to Figure 1 and Figure 3 , the front push feeding assembly includes a front push cylinder 7 and a feeding push block 12.
