Description

Technical Field

[0001] This utility model belongs to the field of cutting fixture technology, specifically relating to a non-destructive cutting fixture for polytetrafluoroethylene sleeves. Background Technology

[0002] The PTFE sleeve non-destructive cutting fixture is a specialized tool used to precisely and efficiently cut PTFE sleeves while maintaining the integrity and performance of the material, ensuring neat, burr-free cut edges. It is suitable for protecting electronic components and cables in various precision instruments and equipment.

[0003] Due to the special properties of polytetrafluoroethylene (PTFE) tubing, when processing it using a conventional tubing cutting machine, the pressure of the feed wheel and the design structure of the cutting head prevent the tubing opening from maintaining a circular shape. As a result, the finished product is diamond-shaped and unusable. PTFE tubing is still cut manually, leading to low production efficiency. Therefore, this invention proposes a non-destructive cutting fixture for PTFE tubing. Utility Model Content

[0004] The purpose of this invention is to solve the problems that existing ordinary sleeve cutting machines cause deformation at both ends of polytetrafluoroethylene sleeves after cutting, making the products unusable, and the low production efficiency of manual cutting. Therefore, a non-destructive cutting fixture for polytetrafluoroethylene sleeves is proposed.

[0005] The objective of this utility model is achieved through the following technical solution.

[0006] This utility model provides a non-destructive cutting fixture for polytetrafluoroethylene (PTFE) sleeves, comprising: a base; a support fixedly connected to one side of the top of the base; the middle of the rear half of the top of the support is inclined; the front half of the top of the support is a deep groove for easy collection of the cut sleeves; baffles are integrally machined on both sides of the rear half of the top of the support, with coaxial holes on the baffles; a positioning scale rod is slidably installed in the hole of the right baffle of the top of the support, and the positioning scale rod is moved and secured by a first fastening screw; a replaceable sleeve inlet is installed in the hole of the left baffle of the top of the support; a column is fixedly connected to the top of the base near the support; a speed-regulating motor is fixedly connected to the upper end of one side of the column; an eccentric wheel is fixedly connected to the output end of the speed-regulating motor; the eccentric wheel is located on the other side of the column, and the end face of the eccentric wheel is rotatably connected to... The device includes a transmission rod and a linear bearing, which are bolted to the column. The transmission rod passes through the interior of the linear bearing and slides within it. A connecting rod is threaded to the end of the transmission rod, and a blade is installed inside the connecting rod. The blade is fixed to the connecting rod by a second fastening screw. A speed-regulating motor drives an eccentric wheel to rotate, causing the transmission rod to move up and down, thus cutting the PTFE sleeve. The blade has a 30° inclination angle, which prevents the sleeve cut from closing and avoids damage to the PTFE sleeve. The cutting length can be controlled by adjusting the first fastening screw installed on the right side baffle at the top of the support and sliding the positioning scale rod. By changing the diameter of the replaceable sleeve inlet installed on the left side baffle at the top of the support, sleeves of different diameters can be cut.

[0007] In this utility model, preferably, the outer side of the positioning scale rod is provided with scale.

[0008] In this utility model, preferably, the middle part of the rear half of the top of the support is an inclined structure, and the front half of the top of the support is a deep groove structure, which facilitates the collection of the sleeve after cutting.

[0009] In this invention, preferably, the speed-regulating motor and the speed-regulating controller are electrically connected.

[0010] Working principle

[0011] In use, the clamp uses a support on the base and a positioning scale rod to fix and guide the PTFE sleeve, facilitating precise control of the cutting length. The middle of the rear half of the top of the support is designed with an inclined structure to facilitate the collection of the sleeve after cutting. The cutting action is driven by a speed-regulating motor, and the speed of the motor can be controlled by a speed controller to adjust the cutting speed. The eccentric wheel connected to the output end of the speed-regulating motor converts the rotary motion into linear motion through a transmission rod. The transmission rod is slidably connected inside a linear bearing to ensure smooth movement. The connecting rod at the bottom of the transmission rod contains a blade. The blade is fixed by the second fastening screw. When the speed-regulating motor starts, the eccentric wheel rotates, driving the transmission rod to move up and down, thereby causing the connecting rod and the blade to perform the cutting action. The blade is designed with a certain angle to ensure that the cut end of the sleeve does not close after cutting, avoiding damage to the PTFE sleeve. The cutting length can be controlled by adjusting the position of the positioning scale rod. By changing the diameter of the sleeve inlet on the left side of the support, it can adapt to the cutting of sleeves of different diameters. The linear bearing is fixed to the column by bolts, ensuring the stability of the entire cutting system. The entire cutting process is efficient, precise, and does not damage the sleeve.

[0012] Beneficial effects

[0013] This utility model designs a non-destructive cutting fixture for PTFE sleeves. The blade has a specific angle, allowing the cut to remain open without damaging the PTFE sleeve. Adjusting the right-side positioning scale rod controls the cutting length. Changing the diameter of the left-side sleeve inlet allows for cutting sleeves of different diameters. A speed controller allows for different hand speeds to meet operator needs. The design is simple, easy to operate, and effectively improves the production efficiency of PTFE sleeves.

[0014] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a scientific and reasonable structure, is safe and convenient to use, and provides great help to people. Attached Figure Description
