Description

Technical Field

[0001] This utility model relates to the field of robotic arm processing technology, and in particular to a conveying device for processing robotic arm shafts. Background Technology

[0002] Currently, the processing of shaft-type workpieces typically involves placing the shaft on a housing and transporting it to the grinding machine using tools such as trolleys. Manual loading and processing follow, resulting in low efficiency. Furthermore, since shaft-type workpieces are usually stacked in the housing, collisions between adjacent workpieces during transport can affect their quality. While some conveyor belts are used, the lack of clamping mechanisms allows the shafts to roll freely during transport, increasing the risk of them falling off and hindering stable transport. Therefore, solutions to these problems are needed. Utility Model Content

[0007] Preferably, the length adjustment mechanism includes an adjustment knob mounted on the upper part of the mounting base and a gear mounted on the bottom end of the adjustment knob shaft. Both sides of the gear are meshed with racks, and one end of the racks is fixedly connected to the mounting base.

[0008] Preferably, the clamping mechanism includes a spring installed at the bottom of the second mounting groove and a load-bearing rod fixed to the upper end of the spring.

A belt 7 is sleeved between the two pulleys, which facilitates the rotation of the drive rollers 1 on both sides; the other end of the belt 7 is sleeved on the drive shaft of the drive roller 1 on the other side.

[0020] In this utility model, the conveying mechanism includes a mounting base and mounting seats 13 fixed to both ends of the top surface of the mounting base. The mounting base facilitates the installation of the length adjustment mechanism and the flexible connecting seat 8; the mounting seats 13 facilitate the installation of the load-bearing rod 15; the bottom of the mounting seat 13 is equipped with a flexible connecting seat 8 that connects to the conveyor belt 2, and the flexible connecting seat 8 facilitates the deformation of the bottom on the roller; the flexible connecting seat 8 has a first mounting groove laterally opened inside, which facilitates the installation of the length adjustment mechanism; the length adjustment mechanism is installed in the first mounting groove, and the mounting seat 13 has a second mounting groove inside, which facilitates the installation of the load-bearing rod 15; and a clamping mechanism is installed at the upper end of the mounting seat 13.

[0021] Working principle: When using this utility model, first adjust the spacing of the conveying mechanism according to the shaft length. Rotate the adjustment knob 10 to drive the lower gear 11 to rotate. The gear 11 meshes with the racks 12 on both sides, thereby causing the racks 12 to drive the mounting base 13 to move inward. After determining the spacing, turn on the motor. The motor drives the drive roller 1 to rotate. The drive roller 1 drives the other drive roller 1 to rotate through the belt 7 on one side, thereby causing the conveyor belt 2 to rotate. During the operation of the conveyor belt 2, the transmission roller 5 provides a certain support for the conveyor belt 2. Place the shaft on the load-bearing platform inside the clamp 17. The load-bearing platform is driven by gravity to support the shaft. The weight bar 15 is pressed down, thereby the hinged connecting rod 16 drives the limiting post 19 to move inward. Since the limiting post 19 is connected to the clamp 17, the clamp 17 will automatically clamp the shaft and send it to the other end. At the other end, the shaft only needs to be lifted up slightly, the clamp 17 opens, and the shaft is taken out. When clamping the shaft, due to the plasticity of the inner rubber layer, the friction is increased on the one hand, and the clamp 17 and the shaft surface are closer on the other hand. The bottom flexible connecting seat 8 can deform at the bottom when the conveying device moves onto the roller. After the transportation is completed, the motor is turned off, and the device can be reset by adjusting the knob 10.
