Description

Technical Field

[0001] This application relates to the technical field of motor accessory transportation, and particularly to a workpiece transportation device. Background Art

[0002] During the production process of motor accessories, it is usually necessary to transfer the accessories between different workstations. For cylindrical workpieces (such as motor stators), during transportation, the existing method is to directly place multiple stators in a transportation frame and then place the transportation frame on a transportation trolley for transportation. When using this method for transportation, the staff only needs to place the stators in the transportation frame, which is simple and labor-saving. At the same time, it supports transporting multiple stators at one time, with relatively high efficiency.

[0003] However, in the actual use process, since the stator itself is cylindrical, during the movement of the trolley, the stator will inevitably roll in the transportation frame under the action of inertia. Especially when the transportation trolley experiences bumps or sudden stops, it is easy to cause collisions between the stators or between the stator and the inner wall of the transportation frame, resulting in problems such as chipping and scratching on the stator, which affect the quality of the stator and further affect the subsequent use and assembly. Summary of the Utility Model

[0004] In order to solve the problem of reducing the problems that affect the quality such as chipping and scratching on the stator caused by the rolling of the stator during transportation, this application provides a workpiece transportation device.

Among them, the two jaws 31 are arranged oppositely, and both jaws 31 slide on the slide rail 4. The positioning structure 32 is used to position the jaws 31 after sliding; during use, the distance between the two jaws 31 is adjusted by sliding the jaws 31 to adapt to workpieces of different sizes.

Then, the clamping jaws 31 are positioned by screwing the tightening bolts 321, and at the same time, the distance between adjacent two sets of clamping assemblies 3 is adjusted to avoid collision between two workpieces. After the first shelf 11 is fully placed, the second shelf 11 is placed above the first shelf 11 through the support column 12, so as to facilitate the staff to place a larger number of workpieces on the transport rack 1. After all the workpieces are placed, the staff can carry the overall transport rack 1 onto the conveying trolley and transport it to different processing lines, thereby reducing the occurrence of scratches or chips caused by workpiece collision during transportation while ensuring the overall transportation quantity; in addition, during the process of placing workpieces, the staff can classify workpieces of different sizes and place them in different placement spaces 2, then record the corresponding information on the identification cards, and then place the identification cards in the corresponding placement grooves 6, so as to identify the placed workpieces, thereby facilitating the subsequent picking and using of workpieces between different processing lines.

[0046] Embodiment 2:

[0047] Refer to Figure 6 , the difference between this embodiment and Embodiment 1 is that the positioning structure 32 is composed of a bidirectional lead screw 322, an abutting block 323 and a nut sleeve 324. One end of the bidirectional lead screw 322 rotates on one of the sliding seats 311 in the clamping jaw 31, and the other end of the bidirectional lead screw 322 rotates on the other sliding seat 311 in the clamping jaw 31. There are two nut sleeves 324 and two abutting blocks 323, and one abutting block 323 corresponds to one nut sleeve 324. The two nut sleeves 324 are respectively located on the sides of the bidirectional lead screw 322 with opposite thread directions. The abutting block 323 is fixed to the nut sleeve 324 by bolts, and the nut sleeve 324 is threadedly connected to the bidirectional lead screw 322.

[0048] Refer to Figure 6, one end of the bidirectional lead screw 322 is welded and fixed with a handwheel 326. During use, the staff can drive the bidirectional lead screw 322 to rotate by rotating the handwheel 326, so as to drive the two abutting blocks 323 to approach each other until the two abutting blocks 323 respectively abut against the side walls of the slide rail 4. Then, the positioning of the slide seat 311 can be realized through the frictional force between the abutting block 323 and the slide rail 4. In addition, in order to ensure the clamping stability between the abutting block 323 and the slide rail 4, a clamping groove 325 with a shape matching the shape of the side wall of the slide rail 4 is also provided on the abutting block 323.
