Description

Technical Field

[0001] This utility model relates to the field of temperature control and heating technology, specifically a multi-step temperature control and heating device. Background Technology

[0002] With the increasing application of induction heating power supplies, customers have raised the need for automated heating for diamond drill bit welding. They require the automated process of heating, controlling, and homogenizing the diamond drill bit welding process to be complete and automated. The welding temperature is a hard indicator. Therefore, the heating and homogenization process of the welding temperature is particularly important, and the key to achieving this lies in a multi-step temperature control heating system.

[0003] During the step-by-step heating process, the temperature and time of each stage need to be adjusted according to the outer diameter of the diamond drill bit in order to ensure that the heating curve and time are uniformly matched with the actual object. Traditional step-by-step temperature control heating devices lack the step of measuring the outer diameter of the diamond drill bit, which can easily affect the step-by-step heating effect of the diamond drill bit and achieve fully automated welding heating. Utility Model Content

[0004] The purpose of this invention is to provide a multi-step temperature control heating device. By placing a diamond drill bit on a support platform inside the housing, and then moving a clamping plate to fit the diamond drill bit, a displacement sensor is used to detect the outer diameter of the diamond drill bit. Then, the regulator automatically generates heating steps and heating time to ensure the stability of the diamond drill bit welding temperature, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-step temperature control heating device, comprising:

[0006] Regulator, thermocouple sensor, induction heating power supply and sensor;

[0007] The sensor includes an induction coil and a housing. The induction coil is installed inside the housing. The induction coil of the regulator is electrically connected to the induction heating power supply. The thermocouple sensor is electrically connected to the regulator. A movable box is provided at the bottom of the housing. Two sets of clamping plates are provided above the movable box. Displacement sensors for measuring the outer diameter of diamond drill bits are installed on the clamping plates. The inner cavity of the movable box is provided with a clamping and moving assembly for moving the clamping plates in opposite directions. The clamping and moving assembly and the displacement sensors are electrically connected to the regulator.

[0008] Preferably, the clamping and moving assembly includes a dual-axis screw rotatably connected to the inner cavity of the movable box via bearings. The two ends of the outer side of the dual-axis screw are threadedly connected to a moving seat via threaded sleeves. The clamping plate is mounted on the top of the moving seat. A servo motor is fixed on the side wall of the movable box. The output shaft of the servo motor passes through the inner cavity of the movable box and is fixedly connected to one end of the dual-axis screw.

[0009] Preferably, the bottom of the inner cavity of the housing is rotatably connected to a support platform for supporting the diamond drill bit, and the support platform is equidistant from the clamping plates on both sides.

[0010] Preferably, the movable seat has a through hole, and a limit rod is slidably disposed in the through hole, with both ends of the limit rod fixed inside the movable box.

[0011] Preferably, electric actuators are fixed around the bottom of the housing, and the piston rod of the electric actuator extends downward and is fixed with a connecting block, which is fixed to the outer side wall of the movable box.

[0012] Preferably, a flexible bracket is fixed to the top of the housing, the thermocouple sensor is mounted on the flexible bracket, and one end of the thermocouple sensor is inserted into the housing.

[0013] Preferably, the regulator is equipped with a heating start / stop button and a program start / stop button, and the thermocouple sensor is a type K thermocouple.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model uses a clamping displacement assembly to move two sets of clamping plates toward each other. After the clamping plates are in contact with the diamond drill bit, the outer diameter of the diamond drill bit is detected by a displacement sensor. Then, a multi-step temperature control heating program is formulated based on the outer diameter of the diamond drill bit to ensure that the internal temperature of the diamond drill bit rises evenly and improves the heating efficiency. This avoids excessively long temperature control time, which would waste time, and also avoids insufficient temperature control time, which would result in insufficient step-by-step temperature rise inside the diamond drill bit and affect the stability of the diamond drill bit welding.

[0016] 2. This utility model uses a regulator to set the heating steps and time, and strictly follows the program to heat up, thereby improving the full automation of the equipment. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figures 1-4 The multi-step temperature control heating device shown includes:

[0025] Regulator 1, thermocouple sensor 2, induction heating power supply 3 and sensor 4;

[0026] The sensor 4 includes an induction coil 41 and a housing 42. The induction coil 41 is installed inside the housing 42. The induction coil 41 of the regulator 1 is electrically connected to the induction heating power supply 3, and the thermocouple sensor 2 is electrically connected to the regulator 1. A movable box 5 is provided at the bottom of the housing 42. Two sets of clamping plates 6 are provided above the movable box 5. A displacement sensor 7 for measuring the outer diameter of the diamond drill bit is installed on the clamping plates 6. A clamping and moving assembly 8 for moving the clamping plates 6 in opposite directions is provided in the inner cavity of the movable box 5. The clamping and moving assembly 8 and the displacement sensor 7 are electrically connected to the regulator 1.

[0027] The clamping displacement assembly moves the two sets of clamping plates 6 towards each other. After the clamping plates 6 are in contact with the diamond drill bit, the outer diameter of the diamond drill bit is detected by the displacement sensor 7. Then, a multi-step temperature control heating program is formulated according to the outer diameter of the diamond drill bit to ensure that the internal temperature of the diamond drill bit rises evenly and improves the heating efficiency. This avoids the waste of time caused by excessively long temperature control time, and also avoids the insufficiency of the step-by-step temperature rise inside the diamond drill bit caused by excessively short temperature control time, which would affect the stability of the diamond drill bit welding.

[0028] Among them, such as Figure 3 As shown:

[0029] The clamping and moving assembly 8 includes a dual-axis screw 81 rotatably connected to the inner cavity of the movable box 5 via bearings. The two ends of the outer side of the dual-axis screw 81 are threadedly connected to the moving seats 82 via threaded sleeves. The clamping plate 6 is installed on the top of the moving seats 82. A servo motor 83 is fixed on the side wall of the movable box 5. The output shaft of the servo motor 83 passes through the inner cavity of the movable box 5 and is fixedly connected to one end of the dual-axis screw 81. The threads at both ends of the dual-axis screw 81 are in opposite directions. The servo motor 83 drives the dual-axis screw 81 to rotate. Then, the dual-axis screw 81 drives the moving seats 82 on both sides to move from the outside to the inside via the threaded sleeves, causing the clamping plate 6 to fit against the diamond drill bit. The outer diameter of the diamond drill bit is detected by the displacement sensor 7, and the displacement sensor 7 transmits the detection data to the regulator 1.

[0030] Furthermore, such as Figure 4 As shown:

[0031] The bottom of the inner cavity of the housing 42 is rotatably connected to a support platform 9 for supporting the diamond drill bit. The support platform 9 is equidistant from the clamping plates 6 on both sides. The support platform 9 facilitates the storage and support of the diamond drill bit, and is also used for positioning the diamond drill bit, making it easy for the clamping plates 6 to contact the diamond drill bit and measure the outer diameter of the diamond drill bit. The rotation of the support platform 9 can adjust the angle of the diamond drill bit, enabling multi-angle measurements and improving measurement accuracy.

[0032] Preferred, such as Figure 3 As shown:

[0033] The movable seat 82 has a through hole, and a limit rod 10 is slidably installed in the through hole. The two ends of the limit rod 10 are fixed in the movable box 5. The limit rod 10 is used to support and limit the movable seat 82, ensuring the stability of the movable seat 82 in the movable box 5 and preventing the movable seat 82 from shaking and affecting the accuracy of the detection data of the displacement sensor 7.

[0034] It is worth noting that, such as Figure 2 As shown:

[0035] Electric push rods 11 are fixed around the bottom of housing 42. The piston rod of electric push rod 11 extends downward and is fixed with connecting block 12. Connecting block 12 is fixed on the outer wall of movable box 5. Through the cooperation of electric push rod 11 and connecting block 12, movable box 5 is moved, thereby adjusting the position of clamping plate 6 and displacement sensor 7. This avoids the electric field and magnetic field generated by induction coil 41 after being energized from affecting displacement sensor 7. At the same time, clamping plate 6 is moved out of housing 42, effectively avoiding the impact of high temperature of induction heating on the stability of sensor structure.

[0036] In a further preferred embodiment, such as Figure 1 As shown:

[0037] A flexible bracket 13 is fixed to the top of the housing 42. The thermocouple sensor 2 is mounted on the flexible bracket 13. One end of the thermocouple sensor 2 is inserted into the inside of the housing 42. The thermocouple sensor 2 is mounted by the flexible bracket 13 to avoid contact between the thermocouple sensor 2 and the metal shell of the sensor 4, and to avoid interference from electric and magnetic fields on the thermocouple sensor 2.

[0038] In addition, such as Figure 1 As shown:

[0039] The controller 1 is equipped with a heating start / stop button and a program start / stop button. The thermocouple sensor 2 is a type K thermocouple. The heating start / stop button and the program start / stop button on the controller 1 are used to control the start and stop of the equipment.

[0040] In practical use, the diamond drill bit is placed on the support platform 9 inside the housing 42. Then, the regulator 1 controls the servo motor 83 to drive it. The servo motor 83 drives the dual-axis screw 81 to rotate. Then, the dual-axis screw 81 drives the moving seat 82 to move inside the movable box 5 through the threaded sleeve. The moving seat 82 drives the clamping plate 6 to fit against the diamond drill bit. Then, the displacement sensor 7 detects the distance between the two sets of clamping plates 6. In order to improve the detection accuracy, the diamond drill bit and the support platform 9 can be rotated to adjust the orientation of the diamond drill bit and the measurement can be performed again. The displacement sensor 7 transmits the detected data to the regulator 1. Then, the regulator 1 analyzes the size of the diamond drill bit to determine the appropriate heating steps and temperature control time.

[0041] Taking a total heating time of 60 minutes, a heating process divided into 6 stages, and a final temperature of 600℃ as an example;

[0042] Step 1: Set the target temperature to 200℃ and the heating time to 10 minutes. Step 2: Set the target temperature to 350℃ and the heating time to 10 minutes. Step 3: Set the target temperature to 450℃ and the heating time to 10 minutes. Step 4: Set the target temperature to 550℃ and the heating time to 15 minutes. Step 5: Set the target temperature to 600℃ and the heating time to 10 minutes. Step 6: Set the target temperature to 600℃ and the heating time to 5 minutes.

[0043] Press the heating start / stop button, and the intelligent regulator 1 starts running according to the set program steps, outputting a switch signal to control the induction heating power supply 3 to start running. At the same time, the temperature signal of the thermocouple sensor 2 is fed back to the regulator 1. During the acquisition process, the intelligent regulator 1 adjusts the output signal in real time according to the detected temperature to control the output power of the induction heating power supply 3. Until each set step is completed, the entire heating and temperature equalization process is automatically completed.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
