Steel belt main rotary chuck device

Abstract

The invention discloses a main rotating chuck device for a steel belt, and mainly relates to a rotating clamping device. The main rotating chuck device comprises a main rotating shaft, a main rotatingclamp, a rotating clamp plate and a pneumatic jacking device; a ventilating slot hole axially penetrates through the main rotating shaft; each of two sides of the main rotating clamp is provided witha side plate; a fixed chuck is arranged at top parts of the side plates connected with the main rotating shaft; one side of the rotating clamp plate is provided with a rotating chuck; one side, far away from the rotating chuck, of the rotating clamp plate and the side plates at the two sides are hinged through a hinge shaft; the pneumatic jacking device is located between the bottom face of the main rotating clamp and the rotating clamp plate; and high-pressure gas is supplied to the pneumatic jacking device through the ventilating slot hole. The main rotating chuck device disclosed by the invention has the beneficial effects that a bigger clamping force can be provided for steel rings by adopting a lever principle; after he main rotating chuck device is used for a period of time, the phenomenon of loosened clamping cannot occur; rigid friction is absent between the surface of the steel ring and the clamping end of the chuck, and scratches cannot be generated, so that rate of finishedproducts is greatly increased; the main rotating chuck device is smaller in size of the rotating chuck; and steel rings that can be produced are 90 mm in minimum diameter, so that the main rotating chuck device is capable of producing steel rings of various types.

Description

technical field [0001] The invention relates to a rotary clamping device, in particular to a main rotary chuck device for a steel belt. Background technique [0002] In the Chinese invention patent with the application number of 201720287793.9, a steel belt main rotating chuck device is disclosed. Its structure only relies on two small action cylinders to push the top block vertically upward to provide pressing force to the steel ring. The clamping force of the action cylinder is not enough, and in the process of clamping the steel belt and driving the steel belt to rotate, the steel belt will rub against the clamping end surface of the rigid chuck, which will cause scratches on the surface of the steel belt, resulting in The yield of production is reduced, the existing gripper will not hold tightly for a period of time, and the clamping force is not enough to cause the product to explode in the subsequent welding process. While the existing mechanism brings the above short...

[0002] In the Chinese invention patent with the application number of 201720287793.9, a steel belt main rotary chuck device is disclosed. Its structure only relies on two small action cylinders to vertically push out the top block to provide a pressing force on the steel ring. Two small The clamping force of the action cylinder is not enough, and when the chuck is clamping the steel belt to drive the steel belt to rotate, the steel belt will rub against the surface of the clamping end of the steel chuck, which will cause scratches on the surface of the steel belt, resulting in The yield of production is reduced, and the existing clamps will not be clamped tightly after being used for a period of time, and the clamping force is not enough to make the product explode in the subsequent welding process

While the existing mechanism brings the above-mentioned shortcomings, it is also important that the volume of the entire rotary chuck is increased due to the vertical arrangement of the two small action cylinders, resulting in the minimum diameter of the steel ring that can be produced as 100mm, if a steel ring with a diameter smaller than 100mm is produced, the steel will interfere with the edge of the rotary chuck
