Abstract
The utility model provides a clamping matching structure with an air pressure valve. The clamping matching structure with the air pressure valve comprises an air pressure valve, an inner hole which is formed in the air pressure valve, and a clamping piece which is used for clamping the inner hole. Clamping processing of the air pressure valve is conducted by adoption of the clamping piece, and a condition that a workpiece is large in errors or the workpiece is deformed, due to the shake of the workpiece which is caused by a small clamping area in the process of air pressure valve processing, is avoided.
Description
Technical field
The utility model is specifically related to a kind of and air pressure valve snap-fit structure.
Background technology
A kind of air pressure valve, valve body inner bore is through-hole structure, endoporus is a plurality of stepped constructions, and also is provided with internal thread in the endoporus, and valve body surface is provided with external screw thread, turn around to add man-hour at workpiece, because the maximum outside diameter width is too little, workpiece rocks easily during clamping, also more easily makes workpiece produce distortion during clamping, be unfavorable for processing, the fabricated part error is larger.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of and air pressure valve snap-fit structure, adopts Fastener with the processing of air pressure valve chucking, clamps when avoiding because of the process air pressure valve that area is little to rock workpiece to cause part error large or make workpiece deformation.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: a kind of and air pressure valve snap-fit structure comprise air pressure valve, are located at endoporus in the air pressure valve, are used for being clamped in the shackle member of endoporus.
As preferably, described endoporus is the staged through-hole structure from the bottom along axis direction, and corresponding described shackle member is stepped construction, compact conformation on axially.
As preferably, described endoporus is provided with the first cylindrical cavity, the second cylindrical cavity and internal thread chamber successively from the bottom along axis direction, and the internal diameter size successively decreases successively, and is rational in infrastructure.
As preferably, the external screw thread ladder that described shackle member is provided with successively the first cylindrical ladder that cooperates with the first cylindrical cavity, the second cylindrical ladder that cooperates with the second cylindrical cavity, cooperates with the internal thread chamber along axis direction from the bottom, and the external diameter size increases progressively successively, the corresponding setting with the air valve inner hole structure of shackle member, air valve is tightened, tightly connect on the part maximum outside diameter with gripper chuck, be convenient to processing parts.
As preferably, described internal thread is provided with guiding element in the chamber.Shackle member is tightly lived by shelves to the guiding element position to the endoporus inward turning, stops turn, and workpiece is tightened.
As preferably, described guiding element is provided with three, and uniform ring is located on the inwall in internal thread chamber, and Stability Analysis of Structures is reliable.
Beneficial effect:
The utility model adopts technique scheme that a kind of and air pressure valve snap-fit structure are provided, and adopts Fastener with the processing of air pressure valve chucking, clamps when avoiding because of the process air pressure valve that area is little to rock workpiece to cause part error large or make workpiece deformation.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of and air pressure valve snap-fit structure comprise air pressure valve 1, are located at endoporus 11 in the air pressure valve 1, are used for being clamped in the shackle member 2 of endoporus 11.Described endoporus 11 is the staged through-hole structure from the bottom along axis direction, and corresponding described shackle member 2 is stepped construction, compact conformation on axially.Described endoporus 11 is provided with the first cylindrical cavity 111, the second cylindrical cavity 112 and internal thread chamber 113 successively from the bottom along axis direction, and the internal diameter size successively decreases successively, and is rational in infrastructure.Described shackle member 2 is provided with the first cylindrical ladder 21 that cooperates with the first cylindrical cavity 111, the second cylindrical ladder 22 that cooperates with the second cylindrical cavity 112, the external screw thread ladder 23 that cooperates with internal thread chamber 113 successively from the bottom along axis direction, and the external diameter size increases progressively successively, shackle member 2 and the 11 structural correspondence settings of air valve endoporus, with air valve 1 chucking, tightly connect on part 2 maximum outside diameters with gripper chuck, be convenient to processing parts.113 are provided with guiding element 12 in the described internal thread chamber.Shackle member 2 is torqued-up to the guiding element position in the endoporus 11 and is lived by shelves, stops turn, and workpiece is tightened.Described guiding element 12 is provided with three, and uniform ring is located on the inwall in internal thread chamber 113, and Stability Analysis of Structures is reliable.The utility model adopts technique scheme that a kind of and air pressure valve snap-fit structure are provided, and adopts Fastener with the processing of air pressure valve chucking, clamps when avoiding because of the process air pressure valve that area is little to rock workpiece to cause part error large or make workpiece deformation.
Specific embodiment described herein only is to the explanation for example of the utility model spirit, the utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
