The heat treatment refers to a metal hot working process in which materials are heated, kept warm and cooled in a solid state to obtain desired structures and properties, and the heat treatment is gradually known in the process of moving from the stoneware era to the copper ware era and the iron ware era. Heat treatment is one of the important processes in mechanical manufacturing, and in comparison with other machining processes, heat treatment generally does not change the shape and overall chemical composition of a workpiece, but imparts or improves the usability of the workpiece by changing the microstructure inside the workpiece or changing the chemical composition of the surface of the workpiece. Its feature is to improve the intrinsic quality of the workpiece, which is not normally visible to the naked eye. During heat treatment, a workpiece needs to be clamped, and uniform heating is guaranteed.

The name of the existing application No. CN201921343378.6 is a clamping device for heat treatment of mechanical workpieces, the below of the device main body is provided with a first cylinder, the output end of the first cylinder is connected with the device main body through a first piston rod, the bottom end of the first cylinder is connected with a supporting seat, a fixing hole penetrates through the top of the supporting seat, the inside of the device main body is connected with a motor, the output end of the motor is connected with a turntable through a rotating shaft, the turntable is driven to rotate by the motor through the rotating shaft, so that a pawl can rotate according to the turntable when clamping the workpieces, meanwhile, a second cylinder can push a second piston rod to stretch, so that the second piston rod pushes the first cross rod to be adjusted up and down through a movable bolt, thereby the user is more convenient and rapid when operating the device to clamp the workpieces, and the working efficiency of the user is increased.

However, since the internal temperature of the heat treatment apparatus varies, the gas inside the cylinder is easily affected by the temperature, and the clamping effect is affected.

Disclosure of Invention

An object of this scheme is to provide an output shaft heat treatment device to solve the cylinder and be heated the problem that influences the centre gripping effect.

In order to achieve the above object, the present invention provides an output shaft heat treatment apparatus including: a heating furnace and a containing tray; the containing disc is placed inside the heating furnace; the containing disc is provided with a through hole, and the diameter of the through hole is larger than that of the workpiece; the top of the heating furnace is provided with a motor, and the output end of the motor is vertically downward; the output end of the motor is provided with an output shaft which is fixedly connected; a hole matched with the diameter of the output shaft is formed in the middle of the containing disc, and the output shaft is arranged in the hole; the upper part of the output shaft is provided with threads, and the outer part of the output shaft is provided with a sleeve connected with the output shaft through the threads; a supporting plate fixedly mounted with the sleeve is arranged outside the sleeve; a tension spring is arranged inside the sleeve; the two ends of the tension spring are respectively connected with the sleeve and the abutting plate.

The principle of the scheme is as follows: in placing the holding dish with the work piece, the starter motor for the output shaft is rotatory, and then makes screw thread department rotatory, and then drives the sleeve rotatory thereupon, nevertheless because both ends are equipped with and support the board, and then when making the sleeve rotatory, reciprocates, when driving the sleeve and move down, the inside extension spring of sleeve is tensile, when supporting board bottom contact work piece, the inside dog of sleeve offsets with the sleeve tip, then continues to start at the motor, when the output shaft continues to rotate, holds the dish and supports the board co-rotation.

The scheme has the beneficial effects that: to traditional scheme, this scheme utilization holds the dish and accepts the work piece, it is rotatory to utilize the sleeve simultaneously, can reciprocate simultaneously, make bottom sharp-pointed form and work piece contact, make to the board support the work piece, the extension spring can guarantee to support the board can with the work piece contact, when supporting the work piece, and leave elasticity between the work piece, can guarantee to support the board when the work piece is heated the inflation, can upwards move relatively, make the work piece not return and damage, simultaneously can rotate under the drive of motor, carry out the thermally equivalent under the high temperature in the heating furnace, need not utilize the cylinder just can the centre gripping work piece, and then can centre gripping work piece always. Meanwhile, the diameter of the through hole is larger than that of the workpiece, so that a gap is reserved when the workpiece is heated to expand, and the normal precision of the workpiece is not affected.

Further, a base is arranged at the bottom of the heating furnace and made of heat insulation materials. The temperature that not only can completely cut off the heating furnace and pass out simultaneously keeps off the heating furnace and ground contact, influences the temperature on ground or damages the article on ground.

Two groups of thermoelectric loops are formed when the metal to be tested is contacted with the two electrodes: a group of thermoelectric circuits consisting of the metal to be tested and the copper electrodes 13; and the other group of thermoelectric loops consists of constantan and copper wires. Because the electrodes are uniformly heated, the insulator 14 has good thermal conductivity, so that the two thermoelectric loops have the same joint temperature, and the corresponding potential is controlled by the temperature difference of the two points, and is further transmitted to the amplifier and then transmitted to the divider, so as to obtain the potential difference.

The larger the potential difference is judged by utilizing the obtained potential difference, the larger the temperature difference between the workpiece and the clamping block 8 is, and the overhigh heating of the workpiece is further shown, meanwhile, according to the thermal expansion characteristic, the controller controls the air cylinder 15 to stretch back and forth, so that the clamping block 8 moves back, and further the workpiece is enabled to leave a thermal expansion gap for subsequent use. Meanwhile, the temperature can be accurately judged according to the judgment of the magnitude of the potential difference on the temperature, and other parts in the heating furnace cannot be influenced.

Utilize the cylinder not only can promote the clamp splice motion, press from both sides tightly the work piece, the cylinder can the induction heating furnace temperature simultaneously, utilizes the characteristic of cylinder, and transmission signal is final to the controller in when temperature variation, and then the controller carries out tight adjustment of clamp to the work piece, becomes the advantage by the disadvantage, carries out real-time adjustment to the work piece, reduces the damage that the clamp of work piece caused excessively tightly simultaneously.
