Description

Technical Field

[0001] The utility model relates to an assembly device, in particular to a guide wheel bracket assembly device, belonging to the technical field of mechanical equipment processing. Background Art

[0002] Crawler wheels have strong load-bearing capacity and strong adaptability to terrain, so they are widely used as the traveling mechanisms of large machinery such as excavators and bulldozers. Crawler wheels generally include crawlers and driving wheels, guide wheels, idlers, carrier rollers, etc. arranged inside the crawlers, commonly known as the four wheels and one belt. They are directly related to the working performance and traveling performance of the excavator. Among them, the function of the guide wheel is to guide the correct rotation of the crawler.

[0003] In the Chinese patent application publication specification CN203649961U, a guide wheel bracket clamping device is disclosed. It has front and rear claws arranged at the front and rear parts of the clamping disc, an actuator arranged between the left and right claws and the clamping disc for driving the left and right claws to move radially, detachable pads are respectively arranged on the top surfaces of the front ends of the left and right claws, and the left claw, the right claw and the front claw are arranged on the clamping disc so as to be movable along the radial direction of the clamping disc. The guide wheel bracket is clamped between the left claw, the right claw, the front claw and the rear claw.

[0004] Although the above patent clamps the guide wheel bracket by the left claw, the right claw, the front claw and the rear claw during use, its translation needs to be realized by rotating the lead screw respectively, making the clamping operation of the guide wheel bracket relatively cumbersome. At the same time, after clamping the guide wheel, the guide wheel is fixed, and at this time, the guide wheel cannot rotate according to the actual situation of the bracket assembly, resulting in an impact on the assembly of the bracket.

[0005] Therefore, a guide wheel bracket assembly device is proposed here. Summary of the Utility Model
