DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 , the utility model provides a technical solution:

[0025] A heat treatment device for processing a straight shank end mill comprises a base frame 1, a positioning mechanism 2 is arranged on the top of the base frame 1 for adapting to straight shank end mills of different specifications and sizes, and the positioning mechanism 2 comprises:

[0026] The adapter assembly 21 is arranged on the top of the base frame 1, and includes a mounting box 211 fixedly mounted on the top of the base frame 1. A driving motor 212 is fixedly mounted on the bottom of the mounting box 211. The driving motor 212 is a three-phase asynchronous motor, which is electrically connected to an external power supply and is opened and closed by a person operating the control panel. A motor shaft 213 is rotatably mounted on the output end of the driving motor 212. A heating mechanism 3 is arranged on the top of the mounting box 211;

[0027] The rotating assembly 22 is arranged inside the mounting box 211 of the base frame 1, and includes a rotating disk 221 fixedly mounted on the top of the motor shaft 213. Two sliding grooves 222 are provided on the top of the rotating disk 221. A limiting column 223 is fixedly mounted inside the sliding groove 222. A return spring 224 is movably mounted on the surface of the limiting column 223. The two return springs 224 push two sliders 225 to move toward each other through their own elasticity to clamp the straight shank end mill and reset the slider 225. The surface of the limiting column 223 is mounted with a slider 225. A clamping block 226 is fixedly mounted on the top of the slider 225. The V-mouth end of the clamping block 226 is fixedly wrapped with a rubber skin 227. The installed rubber skin 227 increases the friction with the straight-shank end mill when the straight-shank end mill is clamped. The top end of the motor shaft 213 passes through the bottom plate of the installation box 211 and is fixedly connected to the turntable 221. The slider 225 slides in the sliding groove 222. By providing a rotating component 22, the two clamping blocks 226 move in opposite directions to squeeze the reset spring 224 to adjust the distance between the two clamping blocks 226, thereby achieving clamping and fixing of straight-shank end mills of different specifications and sizes, thereby improving the versatility and flexibility of the device.

[0028] In this embodiment, the heating mechanism 3 includes a heating tube 31 fixedly installed on the top of the installation box 211, and a heating wire 32 is fixedly installed inside the heating tube 31. The material of the heating wire 32 is iron-chromium-aluminum-nickel-chromium. The heating wire 32 is heated by a heater 34, and the heat of the heating wire 32 heats the straight-shank end mill. The lower end of the heating wire 32 passes through the right side wall of the heating tube 31 and is fixedly connected to the heater 34. The model of the heater 34 is pt100, which is electrically connected to an external power supply and is turned on and off by a person operating the control panel. A through hole 33 is opened at the bottom of the adapter component 21, and the top of the heating tube 31 is clamped. There is a top cover 35, and an air hole 36 is opened on the top of the top cover 35. The internal space of the heating tube 31 is connected with the internal space of the installation box 211 through the through hole 33 opened at the bottom. The shape of the heating wire 32 is spiral. By providing the adapter component 21 and the heating mechanism 3, the driving motor 212 drives the motor shaft 213 to rotate, and the motor shaft 213 drives the rotating component 22 to rotate, thereby realizing the rotation of the straight shank end mill. At the same time, the heating wire 32 is threaded, and the straight shank end mill rotates inside the heating wire 32, thereby realizing all-round heating of the straight shank end mill, so that the straight shank end mill is heated evenly.

[0029] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0030] During operation, the user first opens the top cover 35 and inserts the straight shank end mill between the two clamping blocks 226, and then covers the top cover 35 on the top of the heating tube 31. The two return springs 224 push the two sliders 225 to move toward each other through their own elasticity to clamp the straight shank end mill. Then the heater 34 heats the heating wire 32, and at the same time drives the motor 212 to drive the motor shaft 213 to rotate. The motor shaft 213 drives the rotating assembly 22 to rotate, so that the straight shank end mill rotates, and the straight shank end mill rotates inside the heating wire 32, heating the straight shank end mill in all directions. The internal hot air is discharged through the air hole 36 to complete the heat treatment of the straight shank end mill.
