Referring to fig. 1-2, a handling device 100 according to an embodiment of the present application is configured to handle a workpiece on a conveyor chain, where a slotted hole is provided on the conveyor chain, and the handling device 100 includes a vehicle body 10 and a connection mechanism 20.

The body 10 is for placing a workpiece, the body 10 comprising a base 11 for placing on a conveyor chain, the base 11 having a bottom side 111 in a first direction a. The connecting mechanism 20 is arranged on the base 11, and the connecting mechanism 20 comprises a connecting piece 21 penetrating through the base 11 along the first direction A, and one end of the connecting piece 21 extending out of the bottom side 111 is used for being matched and connected with the oblong hole.

The carrying device 100 is provided with a vehicle body 10 for carrying a workpiece, and a connecting mechanism 20 is arranged on a base 11 of the vehicle body 10, wherein the connecting mechanism 20 comprises a connecting piece 21, and one end of the connecting piece 21 extending out of a bottom side 111 is matched and connected with a slotted hole of a conveying chain. Because the connecting piece 21 is matched with the oblong hole, the shaking of the connecting piece 21 in the oblong hole is reduced, so that the vehicle body 10 is positioned relative to the conveying chain, and the swinging of the vehicle body 10 relative to the conveying chain in the process that the vehicle body 10 moves along with the conveying chain is reduced, and the carrying device 100 moves along with the conveying chain more stably.

Specifically, the connector 21 is clearance fitted with the oblong hole.

In one embodiment, the tolerance for the clearance fit of the connector 21 with the oblong hole is H6/f5. The inventor of the present application has calculated that when the vehicle body 10 swings by 1mm, the rotation angle of the connecting piece 21 is 1.54 °, the wear on one side of the connecting piece 21 is 0.21mm, and the wear on both sides of the connecting piece 21 is 0.42mm, so that the wear of the connecting piece 21 is reduced, the reliability of the connecting piece 21 is improved, and the service life of the carrying device 100 is prolonged.

FIG. 3 is a cross-sectional view of a coupling mechanism according to one embodiment of the present application; fig. 4 is a partial schematic view of the connection mechanism in the embodiment shown in fig. 3.

In some embodiments, as shown in fig. 1 and 3-4, the base 11 has a top side 112 disposed opposite the bottom side 111 along the first direction a. The connecting mechanism 20 further comprises a sleeve 22 connected to the top side 112, and an end of the connecting member 21 away from the bottom side 111 along the first direction a movably penetrates through the sleeve 22, so that an end of the connecting member 21 near the bottom side 111 along the first direction a can extend out of the bottom side 111 or retract into the base 11. Thus, the sleeve 22 is provided to mount the connection mechanism 20 to the base 11 through the sleeve 22. In use, the connecting piece 21 is moved towards the side close to the sleeve 22 along the first direction a, and one end of the connecting piece 21 close to the bottom side 111 along the first direction a extends out of the base 11 and penetrates into the oblong hole of the conveying chain, so that the carrying device 100 is positioned relative to the conveying chain and moves along with the conveying chain. When it is necessary to move the carrying device 100 relative to the conveyor chain, the connecting member 21 is moved in the first direction a toward the side closer to the sleeve 22, and the connecting member 21 is retracted into the base 11 at the end closer to the base 11 in the first direction a, so that the connection between the carrying device 100 and the conveyor chain is released, and the carrying device 100 can freely move on the conveyor chain.

In some embodiments, as shown in fig. 1 and 3, the sleeve 22 is provided with a first channel 221 and a second channel 222 that each extend through the sleeve 22 in a radial direction of the sleeve 22, the first channel 221 extends in a first direction a, the second channel 222 communicates with an end of the first channel 221 near the base 11 in the first direction a, and the second channel 222 extends in a circumferential direction of the sleeve 22. The connecting mechanism 20 further comprises a pressing plate 23 and a limiting piece 24 with one end connected with the pressing plate 23, the pressing plate 23 is sleeved on the part of the connecting piece 21 located in the sleeve 22, the limiting piece 24 extends along the radial direction of the sleeve 22, and one end, away from the pressing plate 23, of the limiting piece 24 penetrates out of the first channel 221 or the second channel 222. The connection mechanism 20 further includes an elastic member 25 connected between the pressing plate 23 and the top side 112, and an elastic force of the elastic member 25 can move the pressing plate 23 in the first direction a toward a side away from the base 11 relative to the base 11. Thus, by providing the sleeve 22 with the first channel 221 extending in the first direction a, the stopper 24 can move in the first channel 221 in the first direction a, so that the connecting member 21 connected to the stopper 24 by the pressing plate 23 can move in the first direction a, and thus the end of the connecting member 21 near the base 11 in the first direction a can extend out of the bottom side 111 or retract into the base 11. By providing the elastic member 25 connected between the pressing plate 23 and the base 11, the elastic force of the elastic member 25 can act on the pressing plate 23 to push the pressing plate 23 toward the end of the first channel 221 away from the base 11, thereby realizing automatic retraction of the connecting member 21 into the base 11 along the first direction a. By providing the second channel 222 on the sleeve 22, one end of the second channel 222 is communicated with one end of the first channel 221, which is close to the base 11 along the first direction a, so that when the limiting member 24 is located in the second channel 222, the limiting member 24 is limited by the second channel 222 along the first direction a, and the limiting member 24 is blocked from moving along the first direction a in a direction away from the base 11, so that one end of the connecting member 21, which is close to the base 11 along the first direction a, can keep a state of extending out of the bottom side 111, and the connecting member 21 is connected with a conveying chain.

Optionally, the stopper 24 is screwed with the pressing plate 23.

In some embodiments, as shown in fig. 1 and 3, the sleeve 22 is further provided with a third channel 223 penetrating the sleeve 22 along the radial direction of the sleeve 22, the third channel 223 extends along the first direction a, an end of the third channel 223 near the base 11 along the first direction a communicates with an end of the second channel 222 far from the first channel 221, and a dimension of the third channel 223 along the first direction a is smaller than a dimension of the first channel 221 along the first direction a. Thus, by providing the third channel 223 to limit the movement of the limiting member 24 along the circumferential direction of the sleeve 22, when the limiting member 24 is located in the third channel 223, the limiting member 24 is located at one end of the third channel 223 away from the base 11 under the elastic force of the elastic member 25, so that the limiting member 24 is prevented from entering the first channel 221 from the third channel 223 via the second channel 222, and therefore, when the limiting member 24 is located in the third channel 223, the connecting member 21 can stably maintain the state of protruding from the bottom side 111.

In the actual use process, when the handling device 100 needs to be enabled to freely move on the conveying chain, the limiting piece 24 is operated to enable the limiting piece 24 to enter the first channel 221, and the limiting piece 24 moves towards one end of the first channel 221 away from the base 11 under the elastic force of the elastic piece 25, so that the connecting piece 21 is automatically retracted towards the inside of the base 11 along the first direction A. When the handling device 100 is required to be positioned relative to the conveyor chain, the limiting member 24 is operated to move the limiting member 24 along the first direction a to the end of the first channel 221, which is communicated with the second channel 222, and then the limiting member 24 is operated to move the limiting member 24 along the second channel 222 to the end of the second channel 222, which is communicated with the third channel 223, and after the limiting member 24 enters the third channel 223, the limiting member 24 moves to the end of the third channel 223, which is far away from the base 11, under the elastic force of the elastic member 25, so that the connecting member 21 is kept in a state of extending from the bottom side 111, and is arranged in the oblong hole in a penetrating manner to be positioned relative to the conveyor chain.

In some embodiments, as shown in fig. 1 and 3, the connecting piece 21 includes a rotating piece 211 and a positioning piece 212 that are sequentially disposed along the first direction a and connected to each other, the rotating piece 211 is disposed in the sleeve 22 in a penetrating manner, the positioning piece 212 is disposed in the base 11 in a penetrating manner, the rotating piece 211 can rotate relative to the positioning piece 212 about a first axis parallel to the first direction a, and the pressing plate 23 is sleeved on the rotating piece 211 and fixedly connected to the rotating piece 211. In this way, the rotation member 211 and the limiting member 24 can rotate together around the first axis relative to the positioning member 212, and the rotation of the rotation member 211 and the limiting member 24 does not affect the position of the positioning member 212, so that the positioning member 212 can not rotate when the limiting member 24 is rotated. And since the positioning member 212 is configured to mate with the oblong hole, the positioning member 212 does not hinder the rotation of the rotation member 211 and the stopper 24.

The rotating member 211 is rotatably connected with the fixing seat 26 around the first axis, and the rotating member 211 is in clearance fit with the cavity 263 along the radial direction of the rotating member 211. In this way, the fixing base 26 is disposed such that the positioning member 212 is connected to the rotating member 211 through the fixing base 26, and the rotating member 211 can rotate around the first axis relative to the fixing base 26 by making the rotating member 211 be in clearance fit with the cavity 263 of the fixing base 26 along the radial direction of the rotating member 211, so that the rotating member 211 can rotate around the first axis relative to the positioning member 212.
