[0002] An industrial robot is an automatically controlled, reprogrammable, multi-purpose operating machine that can be programmed on three or more axes. An industrial robot consists of three basic parts: the main body, the drive system, and the control system. Industrial robots are widely used in various industrial fields such as electronics, logistics, and chemical industry.

[0003] After checking, the publication (announcement) number: CN219582884U discloses a clamping structure for an industrial robot. This technology discloses "including a clamping seat installed with an industrial robot, the left and right sides of the middle of the front end of the clamping seat are slidably connected with a middle clamping seat, the left and right sides of the front end of the clamping seat are symmetrically slidably connected with a pair of side clamping seats, the ends of the side clamping seats close to each other and the left and right ends of the middle clamping seat are provided with clamping grooves, a motor is fixedly installed on the front side of the right end of the clamping seat, a threaded rod assembly is installed between the output end of the motor and the rear of the middle clamping seat, and a gear is installed between the rear of the side clamping seats. The gear rack assembly, the motor 2 is fixedly installed at the upper rear corner of the right end of the clamping seat, and a worm gear assembly is installed between the output end of the motor 2 and the rear part of the gear rack assembly. When three steel pipes need to be clamped, one of the steel pipes is first placed between the middle clamping seats, and then the motor 1 is used to drive the bidirectional threaded rod to rotate, so that the middle clamping seat closes the distance to clamp the steel pipe, and then the other two steel pipes are placed on both sides of the middle clamping seat respectively, and finally the motor 2 is used to drive the worm to rotate, so that the side clamping seat closes the distance to cooperate with the middle clamping seat to clamp the steel pipe, so that the three steel pipes can be clamped at the same time, thereby reducing costs.

[0004] However, the above-mentioned clamping structure for industrial robots has the following disadvantages:

[0005] 1. The middle clamp seat of the patent is fixedly connected to one end of the middle slider, and the other end of the middle slider is installed on the bidirectional threaded rod, while the side clamp seat is fixedly connected to one end of the side slider, and the other end of the side slider is fixedly installed on one end of the rack. Therefore, when the diameter of the steel pipe to be clamped changes greatly, the middle clamp seat and the side clamp seat cannot be easily disassembled and replaced, and the entire clamping structure needs to be replaced, which results in a smaller scope of application of the clamping structure.

[0006] In order to solve the above problems, the present application proposes a clamping structure for an industrial robot. Utility Model Content
