Description

Technical Field

[0001] The utility model relates to a special clamping device for hub manufacturing. Background Art

[0002] During the manufacturing process, large wheels are large in size (about 1.4 meters wide and 0.45 meters high), heavy (about 100 kilograms), and have high temperatures (about 200 degrees). Therefore, it is difficult to rely on manpower during the production process. Therefore, mechanical claws can be used to assist. Utility Model Content

[0003] The technical problem to be solved by the utility model is: to overcome the deficiencies of the prior art, to provide a special clamping device for manufacturing large wheel hubs, and to solve the current technical problem of difficult circulation in the manufacturing process of large wheel hubs.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A special clamping device for manufacturing large wheel hubs is provided, comprising:

[0006] A base, wherein a slide rail is fixedly provided on the base, two sides of the slide rail extend from two sides of the base respectively, and sliders are provided on both sides of the slide rail;

[0007] A first mechanical claw and a second mechanical claw, wherein the two mechanical claws are respectively connected to the two sliders so that the mechanical claws form a sliding fit with the slide rail;

[0008] The cylinder body of the cylinder is fixedly connected to the first mechanical claw, and the push rod of the cylinder is fixedly connected to the second mechanical claw. The cylinder is extended and retracted to drive the two mechanical claws to perform clamping motion.

[0009] Furthermore, the base is a "sun" shaped structure, which includes a front cavity and a rear cavity, the slide rail is fixed in the front cavity, and the cylinder is arranged in the rear cavity.

[0010] Furthermore, a guide rail seat is fixedly provided on the base, and the slide rail is fixed on the guide rail seat.

[0011] Furthermore, the first mechanical claw and the second mechanical claw both include

[0012] a clamping portion, a first connecting portion, and a second connecting portion;

[0013] The clamping portion is suitable for clamping the wheel hub, the first connecting portion is connected to the slider, and the second connecting portion is connected to the cylinder respectively.

[0014] Furthermore, the clamping portion has an arc-shaped structure.

[0015] Furthermore, a pair of supporting members are provided on the clamping portion, and the supporting members include

[0016] An arc-shaped cradle, wherein the middle portion of the cradle is connected to the mechanical claw via a mounting shaft, and rollers are respectively mounted at both ends of the cradle, and the rollers are adapted to abut against the wheel hub.

[0017] Furthermore, spare shaft holes are respectively provided on the mechanical claws on both sides of the installation shaft, and the spare shaft holes are suitable for matching with the installation shaft.

[0018] Furthermore, the first mechanical claw and the second mechanical claw both have a double-layer structure;

[0019] The mechanical claw comprises an upper plate, a lower plate and a partition plate, and two ends of the partition plate are respectively fixed to the upper plate and the lower plate by welding.

[0020] The beneficial effects of the utility model are:

[0021] Compared with the general clamping device in which one claw is fixed and clamping and loosening are achieved by moving the other claw, the special clamping device for large wheel hub manufacturing of the utility model has two claws moving at the same time, which can achieve more stable clamping of large wheel rims and is not easy to fall off.

[0022] The wheel rim is not a standard circle during the production process, so the front end of a general mechanical gripper is often an arc-shaped clamp, which cannot fit the rim and is easy to fall during the clamping process. This solution is equipped with an arc-shaped cradle and rollers at the front of the mechanical gripper, which can move freely at a certain angle during the clamping process, fully fit the surface of the rim, and clamp more stably.

[0023] Conventional mechanical grippers are of a single size. To accommodate the curvature of the rim, one pair of grippers is required for each rim model. This results in rapid product model changes, cumbersome replacement of the grippers, and high costs. This patent application proposes a spare shaft hole in the gripper for mounting a curved cradle. This allows the mounting position of the curved cradle and the placement of the roller to be changed, enabling the gripping of rims of varying sizes to be achieved quickly and conveniently at a low cost.
