Precise cutting device for polytetrafluoroethylene casing pipes of instruments and meters

Abstract

The invention discloses a precise cutting device for polytetrafluoroethylene casing pipes of instruments and meters. The precise cutting device comprises a cutting length control assembly, a pipe fixing assembly and a cutting assembly; the cutting length control assembly comprises a bottom table, a threaded shaft, a sliding shaft, an end ring, a sliding block, a meshing block, a pull cylinder, a copper sleeve, a locking screw and an adjustable scale plate; the pipe fixing assembly comprises a fixing table, a fixing table thread and a puller screw; the cutting assembly comprises a rod screw, a vertical rod, a rotating rod, a motor and a cutting piece; under-table scales are formed in the edge of the horizontal part of the cutting length control assembly; table shaft holes and table thread shaft holes are formed in the vertical parts of the two ends of the bottom table; the tops of plate-shaped parts at the two ends of the bottom table are each provided with two table top screws; and the end of one of the plate-shaped structures of the bottom table is provided with a spring groove and table top scales. The precise cutting device for the polytetrafluoroethylene casing pipes of the instruments and meters can adapt to casing pipes with different diameters, can precisely control the length of the cut casing pipes, and is suitable for being widely used and popularized.

Description

technical field [0001] The invention belongs to the technical field of instrumentation processing equipment, and in particular relates to a precision cutting device for polytetrafluoroethylene bushings of instruments. Background technique [0002] Instrumentation is an instrument or device used to detect, measure, observe, and calculate various physical quantities, material components, and physical parameters. Vacuum leak detectors, pressure gauges, length measuring instruments, microscopes, multipliers, etc. all belong to instruments and meters. In a broad sense, instruments and meters can also have functions such as automatic control, alarm, signal transmission and data processing, such as for automatic control of industrial production processes. Pneumatic regulating instruments and electric regulating instruments in control, as well as distributed instrument control systems also belong to instrumentation. Instrumentation improves, extends, or supplements human faculties....

AI Technical Summary

Problems solved by technology

[0003] Some parts of existing instruments need to use PTFE sleeves as protection kits. Most of the existing solutions use sawing machines or other cutting devices to cut the sleeves. It is difficult for such equipment to control the cutting of the sleeves more accurately. length; it is difficult to clamp the casing firmly during the cutting process; the length of the casing can be controlled more accurately by using a lathe, but the casing will rotate at a high speed during the cutting process, and it is difficult to cut a long casing
