Description

Technical Field

[0001] The utility model relates to a welding and alignment tooling, in particular to a guide wheel welding and alignment tooling, belonging to the technical field of guide wheels. Background Technique

[0002] The crawler-type traveling mechanism is the traveling component of crawler-type traveling machinery and equipment. The crawler traveling mechanism mainly consists of a guide wheel, a tensioning device, a crawler frame, idler wheels, a driving device, carrier wheels, and crawler plates, etc. Among them, the guide wheel is used for the guidance of the traveling mechanism. The guide wheel is composed of a rim, a web, and a hub by welding. Therefore, it is necessary to use tooling to carry out alignment and clamping on it to facilitate subsequent welding.

[0003] In a guide wheel welding and alignment tooling disclosed in the Chinese Patent Application Publication Specification CN217727636U, manually turning the adjusting rod drives the cross shaft to rotate through the first bevel gear and the second bevel gear. Therefore, the rotating cross shaft can push the jacking sleeve through the thread to jack and clamp it on the inner ring of the hub. Then, place a web at the lower end of the hub, and then manually push the adjusting ring through the grip to rotate on the base through the adjusting groove and the ball. At this time, the rotating adjusting ring pushes the support ring upward through the thread until the support ring abuts against the lower part of the web to support it.

[0004] In the above patent solution, the support ring is moved upward by pushing the grip, so as to support the web. However, since there is a certain distance between the support ring and the web, the worker needs to push the grip to circle around the device multiple times before the support ring can abut against the lower part of the web to support it. Multiple rounds of pushing not only increase the labor intensity of the worker, but also easily lead to fatigue and a decrease in operation efficiency.

[0005] Therefore, a guide wheel welding and alignment tooling is proposed here. Content of the Utility Model

[0006] The utility model provides a guide wheel welding and alignment tooling, which can quickly and conveniently support the web and improve the assembly efficiency of the guide wheel.

[0007] The utility model is realized by the following technical solutions: a guide wheel welding and alignment tooling, including a base and a fixed column fixed on the upper surface of the base. A first alignment mechanism is arranged inside the fixed column, and a second alignment mechanism is arranged on the upper surface of the base.

One end of the threaded cylinder outside the fixed column is fixed with a clamping block.

[0009] The second pair of mechanisms includes a fixed cylinder fixed on the upper surface of the base. The inner wall of the fixed cylinder is in sliding contact with a second threaded rod. The top end of the second threaded rod is fixed with a support block. The top end of the fixed cylinder is rotatably connected with a threaded ring, and the inner wall of the hole of the threaded ring is threadedly connected with the outer surface of the second threaded rod. A limiting groove is opened on the outer surface of the fixed cylinder, and a limiting block is fixed on the inner wall of the fixed cylinder, and the outer surface of the limiting block is slidably connected with the inner wall of the limiting groove.

[0010] Further, a limiting plate is fixed on the inner wall of the through groove, and the inner wall of the hole of the limiting plate is in rotational contact with the outer surface of the first threaded rod.

[0011] Further, a sliding groove is opened on one side of the through groove. A sliding block is fixed on the outer surface of the threaded cylinder, and the outer surface of the sliding block is slidably connected with the inner wall of the sliding groove.

[0016] 1. For this guide wheel welding and pairing tooling, the hub of the guide wheel is sleeved on the fixed column, and then by rotating the rotating rod to drive the driving bevel gear to rotate, the driving bevel gear can drive the first threaded rod to rotate through meshing with the driven bevel gear. The rotation of the first threaded rod can drive the threaded cylinder to move, so as to drive the clamping block to clamp and fix the inner side of the hub of the guide wheel.

[0017] 2.
