Batch tapping device for corrugated pipe

Abstract

The invention relates to a batch tapping device for a corrugated pipe. The batch tapping device comprises a bottom plate, fixing plates, a tapping mechanism and a fixing mechanism, wherein the fixingplates are installed on the upper end face of the bottom plate and are of a bilateral symmetry arrangement structure, and the tapping mechanism and the fixing mechanism are sequentially arranged fromtop to bottom between the left fixing plate and the right fixing plate which are directly opposite. According to the batch tapping device for the corrugated pipe, the design concept that multiple groups of drill bits conduct tapping at the same time is adopted for batch tapping of the corrugated pipe, the tapping mechanism arranged on the device can achieve the function of synchronous working of all the drill bits, then the effect of batch tapping of the corrugated pipe can be achieved, meanwhile, the corrugated pipe can be limited and fixed through the fixing mechanism, and therefore, the tapping effect is enhanced.

Description

technical field [0001] The invention relates to the field of corrugated pipes, in particular to a batch opening device for corrugated pipes. Background technique [0002] Bellows refers to a tubular elastic sensitive element connected by foldable corrugated sheets along the direction of folding and expansion. The wall of the bellows is thin and the sensitivity is high. The measuring range is tens of Pa to tens of MPa. Displacement can be generated under the action of pressure, axial force, lateral force or bending moment. Bellows are widely used in instruments and meters. The main purpose is as a measuring element of pressure measuring instruments to convert pressure into displacement or force. It can be used as a sealing isolation element to separate two media or prevent harmful fluids from entering the measuring part of the equipment. It can also be used as a compensating element to compensate the temperature error of the instrument by using its volume variability. Elasti...

Problems solved by technology

[0003] 1. Due to the long length of the corrugated pipe, the existing corrugated pipe opening device cannot realize the function of batch opening well. If the bellows are to be opened in batches, it will take a lot of manpower to limit and guide it And the storage work after opening, thus reducing the batch opening efficiency of bellows;

[0004] 2. During the process of opening the bellows, due to its own elasticity, it is easy to shift, resulting in poor opening effect, and the existing bellows opening device is only suitable for one specification of bellows opening and can only Holes of one aperture are drilled, thereby reducing the degree of use of the device and the efficiency of batch opening of corrugated pipes
