Chuck positioning and clamping device

Abstract

The invention relates to a chuck positioning and clamping device. The chuck positioning and clamping device comprises an inner sleeve, rotation discs sleeving the inner sleeve, and power sources driving the rotation discs to rotate around the inner sleeve. The chuck positioning and clamping device further comprises a plurality of claw structures. Each claw structure comprises a claw and a slidingblock which are fixedly installed. Transmission is formed between the rotation discs and the sliding blocks through tooth transmission mechanisms. The power sources push the rotation discs to rotate,and through transmission of the tooth transmission mechanisms, separating or reunion movement is formed between the multiple claw structures. The beneficial effects that gear and tooth transmission isaccurate, efficiency is high, and machining and manufacturing are easy are utilized for overcoming the defects that according to a traditional profiling groove guiding and clamping mechanism, profiling groove machining is difficult, the clamping and positioning precision and the clamping force are influenced after profiling groove abrasion, the friction resistance and clamping force attenuation are large, and synchronism of opposite clamping claws is poor; and in addition, through the structure, the axial size of the chuck is shortened, the excess material length is reduced, the material utilization rate is increased, and economic benefits are increased.

Description

technical field [0001] The invention relates to a chuck positioning and clamping device installed on a laser tube cutting machine or a plate-tube integrated machine, which is used for clamping various metal tube materials and profiles. Background technique [0002] For the processing of pipes and profiles of various metal materials, professional laser pipe cutting machines or integrated pipe and plate machines are widely used. Customers are very concerned about clamping force stability, reliability and clamping accuracy when processing pipes. Such as figure 1 , 2 It is shown that the traditional profiling groove guide clamping mechanism has a cylinder 101 to push the disc 102 to rotate, and the profiling groove 103 on the disc drives the movement of the jaw pushing shaft 104 to realize the clutch state of the jaws. The clamping mechanism of the structure has defects such as difficulty in processing the profiling groove, the wear of the profiling groove affects the clampin...

like figure 1 , 2 It is shown that the traditional profiling groove guide clamping mechanism has a cylinder 101 to push the disc 102 to rotate, and the profiling groove 103 on the disc drives the movement of the jaw pushing shaft 104 to realize the clutch state of the jaws. The clamping mechanism of the structure has defects such as difficult processing of the profiling groove, impact on the clamping positioning accuracy and clamping force after the profiling groove is worn, large frictional resistance, large attenuation of the clamping force, and poor synchronization of the relative clamping jaws.
