Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wheel body product clamps, and specifically discloses a wheel body product clamp. Background Art
[0002] The supporting roller is used to support the weight of the crawler equipment and roll on the track rail (track link) or track plate surface. It is also used to limit the track to prevent lateral slippage. When the crawler equipment turns, the supporting roller forces the track to slide on the ground. More supporting rollers can make the ground pressure of the track more uniform, so that it can reduce sinking when walking on soft soil. On the other hand, because the length of the crawler is certain, if there are more supporting rollers, the diameter of each roller must be small, which increases the rolling resistance. Generally speaking, as the crawler walking mechanism of the combine harvester, the number of supporting rollers is often 3~4, and a few use 6.
[0003] Therefore, in the production of crawler walking mechanism, the processing of the supporting roller is very critical. In the processing and production of the supporting roller, the wheel body product fixture is a commonly used clamping fixture.
[0004] In actual production, high-horsepower supporting rollers are heavy and come in many types. Common clamping fixtures have safety hazards or poor versatility, requiring frequent fixture replacement, resulting in high labor intensity and low production efficiency.
[0005] For example, pneumatic chuck clamps are prone to fall off when clamped on the edge of heavy and high-powered supporting rollers, posing a safety hazard. Existing multi-link clamps are unstable, have poor load-bearing capacity, and have a small stroke and poor versatility. When clamping heavy wheel products, multi-link clamps are prone to damage the drive parts (such as the piston rod of the cylinder) due to the shaking of the wheel products. Utility Model Content
