Side door anti-collision pipe core-rod-free type hole punching pipe fitting testing fixture

Abstract

The invention belongs to the technical field of testing fixture equipment, and relates to a side door anti-collision pipe core-rod-free type hole punching pipe fitting testing fixture which comprises a bottom plate, testing fixture simulation blocks are arranged at the two ends of the bottom plate in the length direction respectively, and clamping devices are arranged on the sides, corresponding to the two testing fixture simulation blocks, of the bottom plate respectively. A first zero-veneering reference block and a second zero-veneering reference block are respectively arranged on the other side, corresponding to the two testing fixture simulation blocks, of the bottom plate; a guide rail is arranged on the bottom plate corresponding to the position between the two clamping devices, a movable simulation block is arranged on the guide rail in a sliding fit mode, a dial indicator is arranged on the movable simulation block, and end positioning blocks are arranged at the two ends of the guide rail respectively. The first zero-veneering reference block is provided with a main positioning pin in a matched mode, the second zero-veneering reference block is provided with an auxiliary positioning pin in a matched mode, and the main positioning pin and the auxiliary positioning pin are matched with the corresponding testing fixture simulation blocks respectively. The hole punching pipe fitting testing fixture is simple in operation, and can comprehensively and visually reflect whether the pipe fitting product meets the drawing design requirement.

Description

technical field [0001] The invention belongs to the technical field of inspection tool equipment, and relates to a side door anti-collision pipe without a core rod type inspection tool for perforated and punched pipe fittings. Background technique [0002] In the prior art, after a series of processing processes such as punching, it is necessary to check whether the processed pipe fittings are qualified products. At present, it is often difficult to obtain accurate and accurate data conclusions without external causes by direct measurement with existing measurement tools. The process capability index of CPK can be determined by means of inspection tools to realize process capability analysis SPC data collection. SUMMARY OF THE INVENTION [0003] Aiming at the above problems, the present invention provides a coreless punching pipe fitting inspection tool for side door anti-collision pipe, which is simple to operate and can comprehensively and intuitively reflect whether the...
