Embodiment Construction

[0039] The specific embodiment of the present invention is shown in accompanying drawing, and its structure is made up of two shells 1 with the same size and symmetry and two spring bell chambers 2 with the same size and symmetry; Inside the shell 1, it is fastened by screws; an inner cavity 3 is formed between two spring bellows 2, and an outer cavity 4 is formed between the shell 1 and the spring bellows 2; a reference plane is processed on an outer surface of the shell 1.

[0040] The shell 1 is made of metal; a spring bellows installation groove 5 is processed on its inner side, and a plurality of air grooves 6 are processed on the bottom surface of the spring bellows installation groove 5; an annular groove is machined on the inner side of the shell 1 near the edge of the inner diameter 7. A squeeze locking piece 8 is formed at the inner diameter of the shell 1; a plurality of corresponding countersunk holes and threaded holes for screw installation are processed on the ou...

Abstract

The invention discloses a pneumatic forceps holder, relates to the forceps holder for motor braking, and belongs to the novel pneumatic forceps holder both economic and practical. The pneumatic forceps holder is characterized by comprising two symmetrical shells same in size and two symmetrical spring bellows same in size; the spring bellow are oppositely combined and arranged in the shells and fixed through bolts; an inner cavity is formed between the spring bellows, and an outer cavity is formed between the shells and the spring bellows; one outer side face of the shells serves as a level surface to be processed. The pneumatic forceps holder has the advantages that the pneumatic forceps holder is novel in structure, convenient to process, small in size, convenient to mount and use, less n processing difficulty and precision, long in service life, convenient to maintain and replace and the like.

Description

technical field [0001] The pneumatic clamp of the invention relates to a clamp for motor braking. Background technique [0002] At present, the traditional hydraulic clamping method of the rotary shaft forms a closed annular oil chamber between the clamping sleeve and the component shell. When high-pressure oil is introduced, the oil forces the clamping sleeve to deform, and the deformation of the clamping sleeve is squeezed Rotary axis, through friction to achieve braking action. This clamping method has the following disadvantages: [0003] 1. Since the braking force is mainly provided by high-pressure oil, an additional hydraulic supply system is required in the complete machine. This increases the overall size and cost of the device. [0004] 2. Due to the use of high-pressure oil to force the deformation of the clamping sleeve, it squeezes the rotating shaft to generate friction to achieve the purpose of braking. In order to achieve the expected deformation effect, ...
