[0022] 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.

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.

[0023] Embodiment 1

[0024] In the prior art, when performing reciprocating heating and quenching treatment on an eccentric drill bit, the drill bit needs to be transferred back and forth between the heating device and the quenching pool, which is not only very cumbersome, but also sometimes causes the drill bit to fall during the back and forth transfer process, thus causing unnecessary trouble. In order to solve this technical defect in the prior art, Figure 1-Figure 6As shown, this embodiment proposes an eccentric drill tool production device with high integration and no need to transfer the eccentric drill body 5 multiple times. A control lever 2 is provided at the upper end of the processing table 1 of the device, and a drill tool heating mechanism 3 for automatically cyclically heating the drill bit is provided on the processing table 1. A quenching and cooling mechanism 4 is provided below the drill tool heating mechanism 3. After the staff puts the eccentric drill body 5 into the device, the drill tool heating mechanism 3 will automatically transport and heat the eccentric drill body 5. After the heating is completed, the quenching and cooling mechanism 4 will cool the eccentric drill body 5, thereby completing the heat treatment of the drill bit.

[0025] In order to improve the efficiency of the heat treatment process as much as possible and complete the heat treatment process of multiple eccentric drill bodies 5 at one time, the present embodiment is provided with a drill tool heating mechanism 3. Specifically, the drill tool heating mechanism 3 includes an electric heating box 301 fixedly installed on the processing table 1. A plurality of heating cavities 302 are evenly spaced at the lower end of the electric heating box 301. A heating coil 303 for heating the eccentric drill body 5 is respectively arranged inside each heating cavity 302. A telescopic push rod 304 is fixedly installed at the lower end of the electric heating box 301. The control lever 2 is electrically connected to the telescopic push rod 304 through a wire. During the quenching process, the staff can move the loading disc 305 up and down by controlling the lever 2. The telescopic push rod 304 is electrically connected to the eccentric drill body 5 by a wire. 4 is movably provided with a loading disc 305, and a limiting circular groove 306 is provided on the upper surface of the loading disc 305. The number of the limiting circular grooves 306 matches the number of the heating cavities 302, so that a plurality of eccentric drill bodies 5 can be heat-treated at one time, thereby improving the processing efficiency. The limiting circular grooves 306 are symmetrically provided with limiting clamps 307 for clamping the eccentric drill bodies 5. After the staff puts the eccentric drill body 5 into the limiting circular grooves 306, the two limiting clamps 307 will automatically limit the eccentric drill body 5. Subsequently, the loading disc 305 will move upward under the action of the telescopic push rod 304, thereby transporting the eccentric drill body 5 to the inside of the electric heating box 301 for heating.

[0026] In order to improve the uniformity of contact between the eccentric drill body 5 and the quenching liquid during the quenching process, the present embodiment is provided with a quenching cooling mechanism 4. Specifically, the quenching cooling mechanism 4 includes a quenching box 401 fixedly mounted on the processing table 1, and a rotating disc 402 is movably mounted inside the quenching box 401. A driving motor for driving the rotating disc 402 is fixedly mounted at the bottom of the processing table 1. A coil spring is arranged on the outside of the lower end of the rotating disc 402. When the driving motor is powered on, the rotating disc 402 will rotate a certain number of times. After the driving motor stops running, the rotating disc 402 will reset under the action of the coil spring, a transmission protrusion 403 is arranged on the upper end of the rotating disc 402, a transmission disc 404 is fixedly installed on the lower end of the loading disc 305, the interior of the quenching box 401 is filled with quenching liquid, and the heated eccentric drill body 5 follows the loading disc 305 to move into the interior of the quenching box 401, and will contact with the quenching liquid, thereby completing the quenching process, a transmission groove is opened on the transmission disc 404, and the transmission groove matches the transmission protrusion 403, and when the loading disc 305 moves downward, the transmission protrusion 403 will enter the interior of the transmission groove.

[0027] In this embodiment, when in use, the staff will first vertically place the eccentric drill body 5 into the limiting circular groove 306. Next, the two limiting clamps 307 inside the limiting circular groove 306 will automatically clamp and limit the eccentric drill body 5 under the action of the spring, thereby preventing the eccentric drill body 5 from falling during the heat treatment process.

[0028] Next, the staff will control the lever 2 to retract the telescopic push rod 304 upward. When the telescopic push rod 304 retracts, the loading disc 305 will move upward, thereby transporting the eccentric drill body 5 to the inside of the heating cavity 302. Subsequently, the heating coil 303 will quickly heat the eccentric drill body 5, thereby increasing the hardness of the eccentric drill body 5.

[0029] After a certain period of time, the telescopic push rod 304 will automatically extend downward, thereby transporting the eccentric drill body 5 after heating to the inside of the quenching box 401. Next, the eccentric drill body 5 will come into contact with the quenching liquid to achieve rapid cooling. After cooling for a certain period of time, the telescopic push rod 304 will retract upward again, so that the eccentric drill body 5 will return to the inside of the heating cavity 302 again, and this process will be repeated until the heat treatment process is completed.

[0030] Moreover, after the carrier disc 305 moves into the quenching box 401 , the transmission protrusion 403 cooperates with the transmission disc 404 to make the carrier disc 305 and the rotating disc 402 rotate synchronously, thereby improving the uniformity of contact between the quenching liquid and the eccentric drill body 5 .

[0031] In addition, after the driving motor stops running, the rotating disk 402 will be reset under the action of the coil spring, thereby ensuring that the limiting circular groove 306 and the corresponding heating cavity 302 are still in a coaxial state.

[0032] In this embodiment, by setting up a drill tool heating mechanism 3 and utilizing the mutual cooperation between the carrier disc 305 and the telescopic push rod 304, a plurality of eccentric drill bodies 5 can be subjected to reciprocating heat treatment processing at one time, which can effectively improve the processing efficiency. Moreover, heating and quenching can be completed on one device with high integration and no need to transfer the eccentric drill body 5. In addition, in this embodiment, by setting up a quenching cooling mechanism 4 and utilizing the mutual cooperation between the rotating disc 402 and the transmission disc 404, the carrier disc 305 can be rotated at a uniform speed during the quenching treatment to improve the uniformity of contact between the quenching liquid and the eccentric drill body 5, and the carrier disc 305 can be automatically reset after rotation to ensure that the eccentric drill body 5 can smoothly return to the interior of the heating cavity 302.

The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
