Hot shrinkage knife handle hot shrinkage integrated machine

Abstract

This application relates to a heat-shrinkable knife handle integrated heat-shrinkable machine, specifically to a heat-shrinkable device for heat-shrinkable knife handles. It includes a mounting base with an internal cavity. A first motor is fixedly connected to the inner bottom wall of the cavity, and a worm gear is fixedly connected to the output shaft of the first motor. A worm wheel meshes with the outer surface of the worm gear. This application, by incorporating components such as a worm gear, worm wheel, first threaded rod, and lifting rod, allows the following operation: After the knife handle is heated, the knife is placed in the handle. An infrared distance sensor detects the tip position of the knife. At this point, the first motor is activated, driving the worm gear to rotate. The worm gear causes the worm wheel and the first threaded rod to rotate together. Through the threaded connection between the first threaded rod and the lifting rod, the lifting rod rises along a limiting cylinder, thereby raising the knife until the infrared distance sensor detects that the tip of the knife has reached a suitable installation position. This allows the device to achieve precise height adjustment of the knife.

Description

Technical Field

[0001] This application relates to the field of heat shrinking equipment for heat shrink tool holders, and in particular to an integrated heat shrinking machine for heat shrink tool holders. Background Technology

[0002] Heat shrink tool holders are high-precision tool clamping systems based on the principle of thermal expansion. They achieve clamping by utilizing the difference in thermal expansion coefficients between special stainless steel tool holders and carbide tools. They are mainly used in precision manufacturing fields such as milling, drilling, mold processing, and aerospace. Their working principle is to heat the tool holder to about 300°C and then insert the tool. The metal cools and shrinks to form a strong fixation. The runout accuracy can reach 0.0025mm, and the dynamic balance stability is better than that of traditional collet structures.

[0003] However, it has been found in the existing technology that when assembling the tool holder and the tool, the operator usually needs to manually adjust the tool assembly position, which affects the accuracy of the tool assembly and results in problems of low accuracy and poor consistency in the existing technology. Utility Model Content

[0004] The purpose of this application is to provide a heat shrink tool holder heat shrink machine, which has the advantages of raising the tool through a lifting mechanism until the infrared distance sensor detects that the top of the tool has reached a suitable installation position, thereby achieving precise adjustment of the tool height and solving the problems mentioned in the background art.

[0005] The heat shrinkable knife handle heat shrinking integrated machine provided in this application adopts the following technical solution: it includes a mounting base, the mounting base has a cavity inside, a first motor is fixedly connected to the inner bottom wall of the cavity, a worm gear is fixedly connected to the output shaft of the first motor, a worm wheel is meshed on the outer surface of the worm gear, a first threaded rod is fixedly connected to the inner wall of the worm wheel, the outer surface of the first threaded rod is rotatably connected to the inner wall of the mounting base, a lifting rod is threadedly connected to the outer surface of the first threaded rod, a limit cylinder is fixedly connected to the inner wall of the mounting base, the inner wall of the limit cylinder is slidably connected to the outer surface of the lifting rod, a knife handle seat is fixedly installed on the upper surface of the mounting base, an infrared distance sensor is provided above the knife handle seat, a limit component is fixedly installed on the inner bottom wall of the cavity, and the inner wall of the limit component is rotatably connected to the outer surface of the worm gear.

[0006] By adopting the above technical solution, a cavity is formed inside the mounting base to achieve cavity positioning. A first motor is installed on the inner bottom wall of the cavity. A worm gear is installed on the output shaft of the first motor and fixed to the output shaft, allowing the first motor to drive the worm gear to rotate. A worm wheel is set on the side of the worm gear, and the worm gear meshes with it, so that when the first motor drives the worm gear to rotate, the worm wheel can rotate. A first threaded rod is installed on the inner wall of the worm wheel and fixed to the worm wheel, allowing the worm wheel to drive the first threaded rod to rotate.

Through the connection between the first threaded rod and the lifting rod, the lifting rod can move up and down, so that the top of the lifting rod can lift the tool for fine adjustment until the infrared distance sensor detects that the top of the tool has reached the appropriate installation position. This allows the device to achieve precise adjustment of the tool height, improving assembly accuracy. The infrared distance sensor can also transmit the detection data to the external PLC control system. By setting a limiting component connected to the worm gear and fixing the bottom surface of the limiting component to the inner bottom wall of the cavity, the limiting component can limit the end of the worm gear, allowing the worm gear to rotate stably.

After the knife holder is heated, the knife is placed inside. An infrared distance sensor detects the tip position of the knife, at which point a first motor is activated, driving the worm gear to rotate. The worm gear, in turn, causes the worm wheel and first threaded rod to rotate together. The threaded connection between the first threaded rod and the lifting rod allows the lifting rod to rise along a limiting cylinder, thus raising the knife until the infrared distance sensor detects that the tip of the knife has reached the appropriate installation position. This allows for precise height adjustment of the knife, improving assembly accuracy. A second motor is then activated, driving a second threaded rod to rotate. The connection between the second threaded rod and a slider allows the slider to rise and fall along a groove, enabling the fixing seat and electromagnetic heating coil to rise and fall automatically. This ensures uniform heating and prevents knife holder deformation or knife loosening. Attached Figure Description
