Description

Technical Field

[0001] The utility model relates to the field of AGV drive assembly assembly, in particular to an AGV differential drive assembly assembly device. Background Art

[0002] The most widely used complete machine drive system in the AGV industry is the differential drive assembly. The specifications of the differential drive assembly are matched according to the tonnage of the complete machine. Since the production of AGV is non-standard customized production, the tonnage of each batch of complete machines is generally different, and the specifications and dimensions of the configured differential drive assembly are not uniform. Due to the non-uniform specifications of the differential drive assembly, AGV complete machine manufacturers generally do not make dedicated assembly platforms. Operators generally place the differential drive assembly on skids for assembly, which is very inconvenient to operate and has relatively low efficiency.

[0003] The structure of the differential drive assembly is very compact. It is necessary to arrange the motor reducer assembly, slewing bearing and other mechanical parts in the limited space of the differential drive frame, and perform the threading and bundling of the motor wire harness. In particular, when the motor reducer assembly is assembled to the differential drive frame, the operator needs to hold the motor reducer assembly with one hand and perform related assembly with the other hand. The operator is very hard-working. At the same time, wooden blocks are used as supports for assembly. The space for assembly operations is limited, and multiple flips are required to realize the assembly of the differential drive assembly and the connection and bundling of the wire harness. The high labor intensity also poses certain safety hazards. Summary of the invention

[0004] The purpose of the utility model is to provide an AGV differential drive assembly assembly device to solve the problem that the AGV differential drive assembly has no suitable assembly platform, has high labor intensity and low operating efficiency.

[0005] The utility model is realized by the following technical solutions:

[0006] A differential drive assembly device for an AGV comprises a base, on which support frames with adjustable spacing are symmetrically arranged through an adjustment mechanism, a height adjustment support device is fixedly installed in the middle of the base, the height adjustment support device is located between two support frames, and a locking mechanism is provided on the base, and the support frame is locked by the locking mechanism.

[0007] Furthermore, the adjustment mechanism includes a bidirectional screw and a slide rail I installed on the base, the bidirectional screw is installed on the base by installing a bearing seat, the bidirectional screw is connected to one support frame through a left-handed screw nut, and the bidirectional screw is connected to another support frame through a right-handed screw nut. The two support frames are slidably connected to the slide rail I through a slider, the left-handed screw nut and the right-handed screw nut are connected to the support frame through a screw nut connecting flange, and a rotating handle is provided at the end of the bidirectional screw.

[0008] Furthermore, the support frame includes a mounting flange plate, a support frame is welded on the mounting flange plate, reinforcing ribs are welded between the support frame and the mounting flange plate, and the mounting flange plate is mounted on a slider located on the slide rail I.

[0009] Furthermore, the height adjustment support device includes a fixed frame, a slide rail II is provided on the fixed frame, a lifting support platform is slidably provided on the slide rail II, and limit blocks are provided at both ends of the slide rail II, and the limit blocks are used to limit the movement of the lifting support platform.

[0010] Furthermore, the lifting support platform includes a height support platform, on which guide sleeves are symmetrically arranged, inside which guide rods are slidably arranged, the top end of the guide rods is connected to the support table, the height support platform is rotatably connected to the bottom end of the left-hand screw, the support table is rotatably connected to the top end of the right-hand screw, the upper end of the left-hand screw and the lower end of the right-hand screw are both threadedly connected to the adjusting sleeve; the bottom of the height support platform is slidably connected to the slide rail II through a slider.

[0011] Furthermore, the locking mechanism includes a positioning bending plate installed on the base, a long hole is opened on the positioning bending plate, a locking bent plate is fixed to the support frame through a locking mechanism mounting seat, the locking bent plate and the locking mechanism mounting seat are fastened by bolts, a light hole is opened on the locking bent plate, the moving trajectory of the light hole is located in the same horizontal plane as the long hole, and the locking bolt passes through the long hole and the light hole and is fastened by a locking nut.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The width of the two support frames can be adjusted by rotating the adjustment mechanism, and the adjustment mechanism can be locked with a locking bolt, which can meet the assembly of differential drive assemblies of all specifications and models, and solve the low efficiency problem of differential drive assembly assembly that can only be assembled with wooden blocks due to the non-uniform size specifications of the differential drive assembly.

[0014] 2. The adjusting sleeve of the rotating lifting support platform can adjust the height of the support platform to support the motor reduction assembly of the differential drive assembly. The operator is freed from the mode of holding the differential drive motor reducer assembly with one hand and performing assembly work with the other hand. He only needs to tighten the bolts of the motor reducer assembly, thereby greatly reducing labor intensity.

[0015] 3. During assembly, there is enough assembly space at the bottom of the differential drive assembly. The wiring harness bundling and threading of the motor assembly are all realized in this space, which fundamentally solves the problem of multiple flipping operations during assembly of the differential drive assembly, and significantly improves production efficiency.
