Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heaters, in particular to a bearing heater. Background Art
[0002] The yoke-type bearing heater is a key maintenance tool for mechanical equipment. Its main function is to realize the principle of thermal expansion and contraction by heating the bearing, so that the bearing can expand, thereby facilitating installation or removal. The structure of the heater is relatively simple, including the shell and base, electric heating element, temperature control system and support structure. The shell and base constitute the basic framework of the heater, while the electric heating element is responsible for generating heat energy. The heating temperature is monitored and controlled by the temperature control system, and the support structure ensures uniform heating between the bearing and the heating element. In actual operation, the working principle of the bearing heater is simple and effective. First, the bearing is installed in place on the support structure, and then the electric heating element is started to generate heat. As the temperature rises, the metal material in the bearing expands and its diameter increases. Once the bearing expands to a sufficient extent, it can be easily disassembled or installed. However, the current bearing heater requires the staff to manually rotate the yoke during use, so that the yoke swings left or right to facilitate the staff to put the bearing workpiece on the yoke. In this process, the user manually rotates the yoke, which not only requires the staff to operate before and after heating, but also may require regular inspection of the heating condition of the bearing during the heating process. This continuous manual operation increases the operating burden of the staff. At the same time, it is inconvenient to remove the bearing workpiece in a high temperature state from the yoke after heating. Utility Model Content

An inner groove is provided on the outer wall of the stepped card plate 9 on one side close to the vertical yoke 4.
[0021] A control panel 2 is installed on one side of the top of the heater housing 1, and the output end of the control panel 2 is electrically connected to the input ends of the worm gear drive unit 11, the dual-axis electric push module 7, the vertical yoke 4, and the horizontal yoke 5;
[0022] A rectangular slide groove 101 is provided at the top of the heater housing 1, and the slider 8 is slidably installed inside the rectangular slide groove 101, and the sliding stability of the slider 8 and the stepped clamping plate 9 is improved by the rectangular slide groove 101;
[0023] The double-axis electric push module 7 drives the slider 8 and the stepped clamping plate 9 to move on the X-axis, so that the stepped clamping plate 9 abuts against the bearing workpiece at the side, thereby ensuring the stability of the bearing workpiece;
[0024] The worm gear drive unit 11 is composed of a stepper motor, a worm gear transmission structure and a rotating shaft 10. The rotating shaft 10 is rotatably mounted inside the support column 3. The top end of the rotating shaft 10 is fixedly connected to the bottom end of the horizontal yoke 5. The stepper motor is mounted inside the housing 6. The output end of the stepper motor drives the rotating shaft 10 to rotate through the worm gear transmission structure.
[0025] The worm gear transmission structure includes an active worm installed at the output end of the stepper motor, and a worm wheel fixed to one end of the surface of the rotating shaft 10. The worm wheel and the active worm are meshed with each other. The stepper motor in the worm gear drive unit 11 drives the rotating shaft 10 and the horizontal yoke 5 to rotate through the worm gear transmission structure, so that the horizontal yoke 5 and the vertical yoke 4 are misaligned.
[0026] The dual-axis electric push module 7 includes a support plate 701 fixed to one side of the bottom of the cavity 102, and a U-shaped table 703 installed on the top of the support plate 701, a lower slide seat 704 is slidably installed on one side of the bottom end of the U-shaped table 703, an X-axis electric push rod 702 is installed on the back of the support plate 701, the top of the piston rod of the X-axis electric push rod 702 is fixedly connected to one side of the outer wall of the lower slide seat 704, a Z-axis electric push rod 705 is installed on the outer wall of the side of the lower slide seat 704 away from the support plate 701, and a convex plate 706 fixedly connected to the bottom end of the slider 8 is installed on the top of the piston rod of the Z-axis electric push rod 705. When it is necessary to clamp the bearing workpiece on the vertical yoke 4, the X-axis electric push rod 702 pushes the lower slide seat 704, the Z-axis electric push rod 705, the convex plate 706, the slider 8, and the stepped clamping plate 9 to move horizontally, so that the bearing workpiece is firmly fixed on the vertical yoke 4, thereby ensuring the heating stability of the bearing workpiece;
[0027] When the bearing workpiece needs to be pushed upward, the staff turns on the Z-axis electric push rod 705 through the control panel 2, and the Z-axis electric push rod 705 drives the embossed plate 706, the slider 8, and the stepped clamping plate 9 upward, thereby creating a certain gap between the bearing workpiece and the top plane of the heater housing 1, so as to facilitate the staff to remove the bearing workpiece from the vertical yoke 4, thereby reducing the chance of direct contact between the staff and high-temperature components and reducing the risk of accidental touch or burns.
[0028] When the embodiment of the present application is in use, the staff first turns on the worm gear drive unit 11 in the casing 6 through the control panel 2 to work, and the worm gear drive unit 11 drives the rotating shaft 10 in the support column 3 to rotate, and the rotating shaft 10 drives the horizontal yoke 5 to swing clockwise or counterclockwise. In this process, the control panel 2 controls the stepping motor in the worm gear drive unit 11 to work according to the set direction, speed, angle, and response time, so that the horizontal yoke 5 and the vertical yoke 4 are misaligned, so as to facilitate the staff to put the bearing workpiece to be heated on the horizontal yoke 5 or the vertical yoke 4. By introducing the electric swing function, the staff can complete the yoke position adjustment and the bearing installation operation more quickly and accurately. After the bearing workpiece is placed on the horizontal yoke 5 and the vertical yoke 4, the staff uses the control panel 2 to make the worm gear drive unit 11, the rotating shaft 10, the horizontal yoke 5 and other components rotate and reset. For the bearing workpiece installed on the vertical yoke 4, the staff controls When the panel 2 turns on the dual-axis electric push module 7 to work, the dual-axis electric push module 7 drives the slider 8 and the stepped clamping plate 9 to move on the X-axis, so as to use the stepped clamping plate 9 to abut the bearing workpiece at the side to ensure the stability of the bearing workpiece. Then the staff turns on the vertical yoke 4 and the horizontal yoke 5 through the control panel 2 to work. The vertical yoke 4 and the horizontal yoke 5 use the metal to generate eddy currents in the alternating magnetic field to make the bearing itself heat up until the bearing workpiece is heated to the required temperature by the vertical yoke 4 and the horizontal yoke 5. After the bearing workpiece is heated, the staff turns on the dual-axis electric push module 7 through the control panel 2 again to work, and the dual-axis electric push module 7 actively pushes the bearing workpiece upward, so that the bearing workpiece is separated from the top of the heater housing 1, so as to facilitate the staff to remove the bearing workpiece from the vertical yoke 4. The heater no longer needs to manually rotate the yoke frequently, but is completed by the dual-axis electric push module 7 and the electric swing function, thereby reducing the labor intensity of the staff.
