Positioning and clamping device for processing the side notch of copper pipe and its application method

Abstract

Provided are a positioning and clamping device for machining a gap in side face of a copper pipe and a using method thereof. The positioning and clamping device structurally comprises a clamp body, a moving block, a cut-in slot, a pipe through hole, a bolt through hole, a bolt, a clamp positioning hole, a U-shaped gap groove, an elastic flexible plate, a supporting plate groove and a supporting plate. The positioning and clamping device achieves positioning and clamping of the copper pipes through three steps, the first step is that the pipe through hole in the clamp body is used for constraining the copper pipe in the horizontal direction, the second step is that the supporting plate is utilized to constrain the copper pipe in the vertical direction, and the third step is that the elastic flexible plate is utilized to horizontally stagger the pipe through hole in the moving block and the pipe through hole in the clamp body so as to tightly press the copper pipe and finally accurate positioning and clamping are achieved. When the gap is machined in the side face of the copper pipe by means of the positioning and clamping device, machining efficiency is high, the pass percent can be remarkably improved to be higher than 90% from the current 30%, and the positioning and clamping device is novel in design, ingenious in concept, simple in structure and easy to operate.

Description

technical field [0001] The invention relates to a positioning and clamping device for processing a notch on the side of a copper pipe and an application method thereof. Background technique [0002] In medicine, in order to further understand and study the adverse effects of cardiovascular stenosis on human health, as well as preventive and therapeutic measures, it is necessary to use mice and rabbits to conduct a large number of scientific experiments, which require a large number of copper tubes, which are 0.5mm in outer diameter. , 0.26mm in inner diameter, 3mm in length, a small-sized test piece, with a 0.12mm clearance gap on the side of the copper tube, using the notch test piece to tighten the blood vessels of experimental animals, simulating the study of human cardiovascular stenosis, the whole copper tube on the market The length is generally 20-100mm. It is easy to cut by horizontal wire cutting, and the 0.12mm transparent gap is processed by wire cutting in the ve...

[0002] In medicine, in order to further understand and study the adverse effects of cardiovascular stenosis on human health, as well as preventive and therapeutic measures, it is necessary to use mice and rabbits to conduct a large number of scientific experiments, which require a large number of copper tubes, which are 0.5mm in outer diameter. , 0.26mm in inner diameter, 3mm in length, a small-sized test piece, with a 0.12mm clearance gap on the side of the copper tube, using the notch test piece to tighten the blood vessels of experimental animals, simulating the study of human cardiovascular stenosis, the whole copper tube on the market The length is generally 20-100mm. It is easy to cut by horizontal wire cutting, and the 0.12mm transparent gap is processed by wire cutting in the vertical direction. It is very difficult to clamp the copper tube placed vertically. Due to the small size of the copper tube, the inner wall is only 0.12mm. mm is thin, and the outer surface is smooth. At present, tweezers are generally used to clamp a single piece, which leads to low processing pass rate and low efficiency. At present, there is a lack of effective positioning and clamping device for the notch on the side of the copper tube and its use method.
