Description

Technical Field

[0001] This utility model relates to the technical field of induction heat treatment devices, and in particular to an induction heat treatment device for a disc-shaped wheel. Background Technology

[0002] An induction heat treatment device is used to heat-treat disc-shaped wheels. When using this device, it is placed on the surface of the disc-shaped wheel, and a medium-frequency current is passed through its inductor, generating an alternating magnetic field around it. The disc-shaped wheel is then placed in this alternating magnetic field. Because the wheel is made of metal, induced currents (eddy currents) are generated within it. According to Joule's law, these eddy currents generate heat due to the wheel's own resistance, causing the wheel to heat up rapidly, thus achieving the heating purpose.

[0003] The inventors discovered in their daily work that the induction heat treatment device still has at least the following problems: When using the disc-shaped wheel induction heat treatment device, the device is placed on the surface of the disc-shaped wheel, and a medium-frequency current is passed through the sensor, generating an alternating magnetic field around the sensor. When the disc-shaped wheel is placed in this alternating magnetic field, induced currents (eddy currents) are generated inside it because the wheel is made of metal. According to Joule's law, these eddy currents generate heat due to the wheel's own resistance, causing the wheel to heat up rapidly. However, in actual use, previous disc-shaped wheel heat treatment inductors used a C-shaped design, requiring a magnetic conductor and extended induction time on the outer circumference of the wheel to maintain the heating temperature. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a disc-shaped wheel induction heat treatment device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a disc-shaped wheel induction heat treatment device, comprising a connecting sleeve, a support plate at the bottom of the connecting sleeve, a connecting rod fixedly connected to one side of the connecting sleeve, a fixing device at the top of the support plate, an adjusting device at one end of the connecting rod, the fixing device comprising an arc block, the top of the arc block being fixedly connected to the bottom of the connecting sleeve, an arc groove being formed at the top of the support plate, the inner wall of the arc groove being slidably connected to the arc block, a support strip being fixedly connected to the bottom of the support plate, first damping rods being fixedly connected to both sides of the support strip, a sliding plate being fixedly connected to the end of the first damping rod away from the support strip, a fixing groove being formed on one side of the arc block, the inner wall of the fixing groove being slidably connected to the sliding plate, a first spring being sleeved on the surface of the first damping rod, one end of the first spring being fixedly connected to one side of the support strip, and the end of the first spring near the first damping rod being fixedly connected to one side of the sliding plate.

[0006] The effect achieved by the above components is as follows: When using the fixing device, the disc-shaped wheel body is manually placed at the bottom of the connecting sleeve, and then the arc block is slid into the arc groove, and then the sliding plate is slid into the fixing groove. The sliding plate is pressed away from the support bar by the first spring, which can effectively restrict the sliding plate inside the fixing groove, and thus effectively restrict the connecting sleeve at the top of the support plate. This makes it easy to place the disc-shaped wheel body in the middle of the support plate and the connecting sleeve. In this way, the part that needs to be hardened can be wrapped by the sensor and heated by the rotation of the wheel body to achieve a rapid heating effect, saving energy and improving production efficiency.

[0007] Preferably, a connecting frame is fixedly connected to the surface of the support plate, a sliding rod is fixedly connected to the inner wall of the connecting frame, an L-shaped plate is slidably sleeved on the surface of the sliding rod, the end of the L-shaped plate away from the sliding rod is located at the top of the connecting frame, a second spring is sleeved on the surface of the sliding rod, one end of the second spring is fixedly connected to the inner wall of the connecting frame near the support plate, and the end of the second spring near the sliding rod is fixedly connected to one side of the L-shaped plate.

[0008] The effect achieved by the above components is that the L-shaped plate is pulled towards the support plate by the second spring, thereby setting the end of the L-shaped plate away from the sliding rod at the top of the connecting sleeve, which can effectively restrict the connecting sleeve to the top of the support plate.

[0009] Preferably, the bottom of the support bar has a groove, and the inner wall of the groove is slidably connected to a limit strip, the two ends of which are located on the side of the sliding plate near the first damping rod.

[0010] The effect achieved by the above components is that the limiting strip is slid into the inside of the groove, and then the two ends of the limiting strip are set on the side of the sliding plate near the first damping rod, so that the sliding plate can be well restricted inside the fixed groove.

[0011] Preferably, a second damping rod is fixedly connected to the inner wall of the groove, the end of the second damping rod away from the groove is fixedly connected to one side of the limiting strip, a third spring is sleeved on the surface of the second damping rod, one end of the third spring is fixedly connected to one side of the inner wall of the groove, and the end of the third spring near the second damping rod is fixedly connected to one side of the limiting strip.

[0012] The effect achieved by the above components is that the limiting strip is pulled towards the groove by the third spring, which can effectively confine the limiting strip inside the groove.

[0013] Preferably, a rectangular frame is fixedly connected to the side of the sliding plate near the first damping rod, and a fixing block is slidably connected to the inner wall of the rectangular frame. The side of the fixing block away from the second damping rod is fixedly connected to the fixing block.

[0014] The effect achieved by the above components is that the fixing block is slid into the inside of the rectangular frame, which can effectively restrict one end of the limiting strip to the side of the sliding plate near the first damping rod.

[0015] Preferably, the adjusting device includes a sliding frame that is slidably fitted onto the surface of the connecting rod. A first bolt is threaded through the top of the sliding frame, and a fixing plate is fixedly connected to the end of the sliding frame away from the connecting rod.

[0016] The effect achieved by the above components is as follows: when using the adjustment device, the sliding frame is manually controlled to slide on the surface of the connecting rod. When the sliding frame slides to the appropriate position, the first bolt is manually controlled to rotate, thereby pressing the first bolt against the top of the connecting rod. This can extend the length of the connecting rod to a certain extent, making it easier to set the connecting sleeve in the appropriate position.

[0017] Preferably, the bottom of the fixing plate has a rectangular groove, the inner wall of the rectangular groove is fixedly connected to a round rod, the surface of the round rod is rotatably fitted with a rotating rod, the end of the rotating rod away from the round rod is slidably fitted with a limiting frame, the end of the limiting frame away from the rotating rod is rotatably inserted with a positioning rod, the two ends of the positioning rod are fitted with support frames, one end of the support frame is fixedly connected to the bottom of the connecting rod, and a second bolt is threaded through one side of the limiting frame.

[0018] The effect achieved by the above components is as follows: when the sliding frame slides to the appropriate position, it drives the rotating rod to rotate on the surface of the round rod, and drives the limiting frame to rotate on the surface of the positioning rod. When it rotates to the appropriate position, the second bolt is manually controlled to rotate, so that the second bolt is pressed against one side of the rotating rod, which can effectively restrict the rotating rod inside the limiting frame.

[0019] Preferably, a third damping rod is fixedly connected to one side of the inner wall of the limiting frame. The end of the third damping rod away from the limiting frame is fixedly connected to the end of the rotating rod away from the round rod. A fourth spring is sleeved on the surface of the third damping rod. One end of the fourth spring is fixedly connected to one side of the inner wall of the limiting frame. The end of the fourth spring near the third damping rod is fixedly connected to one end of the rotating rod.

[0020] The effect achieved by the above components is that the rotating rod is pressed away from the limiting frame by the fourth spring, which makes it easier to control the rotating rod to slide out of the limiting frame.

[0021] In this invention, by setting a fixing device, when using the fixing device, the main body of the disc-shaped wheel is manually placed at the bottom of the connecting sleeve, and then the arc block is slid into the inside of the arc groove, and then the sliding plate is slid into the inside of the fixing groove. The sliding plate is pressed away from the support bar by the first spring, which can effectively restrict the sliding plate inside the fixing groove, and thus effectively restrict the connecting sleeve to the top of the support plate. This makes it easy to place the main body of the disc-shaped wheel between the support plate and the connecting sleeve. In this way, the part that needs to be hardened can be wrapped by the sensor and heated by the rotation of the wheel to achieve a rapid heating effect, saving energy and improving production efficiency.

[0027] Example 1, as Figure 1-4As shown, an induction heat treatment device for a disc-shaped wheel includes a support plate 2 at the bottom of a connecting sleeve 1, a connecting rod 3 fixedly connected to one side of the connecting sleeve 1, a fixing device 4 at the top of the support plate 2, and an adjustment device 5 at one end of the connecting rod 3. When using the induction heat treatment device, the device is placed on the surface of the disc-shaped wheel, and a medium-frequency current is passed through the sensor, generating an alternating magnetic field around the sensor. When the disc-shaped wheel is placed in this alternating magnetic field, eddy currents are induced within it due to the wheel's metal material. According to Joule's law, these eddy currents generate heat under the wheel's own resistance, causing the wheel to heat up rapidly, thus achieving the heating purpose.

[0028] Reference Figure 2 and Figure 3The fixing device 4 includes an arc block 401, the top of which is fixedly connected to the bottom of the connecting sleeve 1. An arc groove 402 is formed on the top of the support plate 2, and the inner wall of the arc groove 402 is slidably connected to the arc block 401. A support strip 408 is fixedly connected to the bottom of the support plate 2, and first damping rods 410 are fixedly connected to both sides of the support strip 408. A sliding plate 409 is fixedly connected to the end of the first damping rod 410 away from the support strip 408. A fixing groove 403 is formed on one side of the arc block 401, and the inner wall of the fixing groove 403 is slidably connected to the sliding plate 409. A first spring 411 is sleeved on the surface of the first damping rod 410, and one end of the first spring 411 is fixedly connected to one side of the support strip 408. The first spring 411 is close to the first damping rod. One end of rod 410 is fixedly connected to one side of sliding plate 409. When using fixing device 4, the disc-shaped wheel body 6 is manually placed at the bottom of connecting sleeve 1, and then the arc block 401 is slid into the arc groove 402, and then the sliding plate 409 is slid into the fixing groove 403. The first spring 411 presses the sliding plate 409 away from the support bar 408, which can effectively restrict the sliding plate 409 inside the fixing groove 403, and thus effectively restrict the connecting sleeve 1 to the top of the support plate 2. This makes it easy to place the disc-shaped wheel body 6 between the support plate 2 and the connecting sleeve 1. A connecting frame 404 is fixedly connected to the surface of the support plate 2, and a sliding rod 405 is fixedly connected to the inner wall of the connecting frame 404. An L-shaped plate 406 is slidably fitted onto the surface of the connecting sleeve 1. The end of the L-shaped plate 406 away from the sliding rod 405 is positioned at the top of the connecting sleeve 1. A second spring 407 is fitted onto the surface of the sliding rod 405. One end of the second spring 407 is fixedly connected to the inner wall of the connecting frame 404 near the support plate 2. The end of the second spring 407 near the sliding rod 405 is fixedly connected to one side of the L-shaped plate 406. By pulling the L-shaped plate 406 towards the support plate 2 using the second spring 407, the end of the L-shaped plate 406 away from the sliding rod 405 is positioned at the top of the connecting sleeve 1. This effectively restricts the connecting sleeve 1 to the top of the support plate 2. A groove 412 is formed at the bottom of the support bar 408. A limit strip 415 is slidably connected to the inner wall of the groove 412. The two ends of the limiting strip 415 are positioned on the side of the sliding plate 409 near the first damping rod 410. Sliding the limiting strip 415 into the groove 412, and then positioning the two ends of the limiting strip 415 on the side of the sliding plate 409 near the first damping rod 410, effectively confines the sliding plate 409 within the fixing groove 403. A second damping rod 413 is fixedly connected to the inner wall of the groove 412. The end of the second damping rod 413 away from the groove 412 is fixedly connected to the side of the limiting strip 415. A third spring 414 is sleeved on the surface of the second damping rod 413. One end of the third spring 414 is fixedly connected to one side of the inner wall of the groove 412, and the end of the third spring 414 near the second damping rod 413 is fixedly connected to the side of the limiting strip 415.The limiting strip 415 is pulled towards the groove 412 by the third spring 414, thus effectively confining the limiting strip 415 inside the groove 412. A rectangular frame 417 is fixedly connected to the side of the sliding plate 409 near the first damping rod 410. A fixing block 416 is slidably connected to the inner wall of the rectangular frame 417. The side of the fixing block 416 away from the second damping rod 413 is fixedly connected to the fixing block 416. Sliding the fixing block 416 into the rectangular frame 417 effectively confines one end of the limiting strip 415 to the side of the sliding plate 409 near the first damping rod 410.

[0029] Reference Figure 4 The adjusting device 5 includes a sliding frame 501, which is slidably fitted onto the surface of the connecting rod 3. A first bolt 503 is threaded through the top of the sliding frame 501. A fixing plate 502 is fixedly connected to the end of the sliding frame 501 away from the connecting rod 3. When using the adjusting device 5, the sliding frame 501 is manually controlled to slide on the surface of the connecting rod 3. When the sliding frame 501 slides to a suitable position, the first bolt 503 is manually controlled to rotate, thereby pressing the first bolt 503 against the top of the connecting rod 3. This can extend the life of the connecting rod to a certain extent. The length of the connecting rod 3 is such that the connecting sleeve 1 can be set in a suitable position. A rectangular groove 504 is provided at the bottom of the fixing plate 502. A round rod 505 is fixedly connected to the inner wall of the rectangular groove 504. A rotating rod 506 is rotatably sleeved on the surface of the round rod 505. A limiting frame 509 is slidably sleeved on the end of the rotating rod 506 away from the round rod 505. A positioning rod 508 is rotatably inserted through the end of the limiting frame 509 away from the rotating rod 506. Support frames 507 are sleeved on both ends of the positioning rod 508. One end of the support frame 507 is fixedly connected to the bottom of the connecting rod 3. A second bolt 510 is threaded through one side of the limiting frame 509. When the sliding frame 501 slides to the appropriate position, it drives the rotating rod 506 to rotate on the surface of the round rod 505, and also drives the limiting frame 509 to rotate on the surface of the positioning rod 508. When it rotates to the appropriate position, the second bolt 510 is manually controlled to rotate, thereby pressing the second bolt 510 against one side of the rotating rod 506. This can effectively restrict the rotating rod 506 inside the limiting frame 509. A third damping rod is fixedly connected to one side of the inner wall of the limiting frame 509. 511, the end of the third damping rod 511 away from the limiting frame 509 is fixedly connected to the end of the rotating rod 506 away from the round rod 505. A fourth spring 512 is sleeved on the surface of the third damping rod 511. One end of the fourth spring 512 is fixedly connected to one side of the inner wall of the limiting frame 509. The end of the fourth spring 512 near the third damping rod 511 is fixedly connected to one end of the rotating rod 506. The fourth spring 512 presses the rotating rod 506 away from the limiting frame 509, which makes it easier to control the rotating rod 506 to slide out of the interior of the limiting frame 509.

[0030] Working principle: When using the disc-shaped wheel induction heat treatment device, the device is fitted onto the surface of the disc-shaped wheel. A medium-frequency current is then passed through the device's inductor, generating an alternating magnetic field around the inductor. Placing the disc-shaped wheel in this alternating magnetic field causes eddy currents to be generated within the metal material. According to Joule's law, these eddy currents generate heat due to the wheel's own resistance, rapidly raising its temperature and achieving the heating purpose. When using the fixing device 4, the disc-shaped wheel body 6 is manually positioned at the bottom of the connecting sleeve 1. The arc block 401 is then slid into the arc groove 402, and the sliding plate 409 is slid into the fixing groove 403. The first spring 411 presses the sliding plate 409 away from the support bar 408, effectively confining the sliding plate 409 within the fixing groove. Inside 403, the third spring 414 pulls the limiting strip 415 towards the groove 412, effectively confining the limiting strip 415 within the groove 412. The fixing block 416 slides into the rectangular frame 417, effectively confining one end of the limiting strip 415 to the side of the sliding plate 409 near the first damping rod 410, thus effectively confining the sliding plate 409 within the fixing groove 403. The second spring 407 pulls the L-shaped plate 406 towards the support plate 2, thereby positioning the end of the L-shaped plate 406 away from the sliding rod 405 at the top of the connecting sleeve 1. This design effectively confines the connecting sleeve 1 to the top of the support plate 2, facilitating the placement of the disc-shaped wheel body 6 between the support plate 2 and the connecting sleeve 1. This allows the portion requiring hardening to be wrapped by the sensor, combined with the wheel's rotational heating to achieve rapid temperature rise, saving energy and improving production efficiency. When using the adjustment device 5, the sliding frame 501 is manually controlled to slide on the surface of the connecting rod 3. When the sliding frame 501 reaches the appropriate position, it drives the rotating rod 506 to rotate on the surface of the round rod 505, and also drives the limiting frame 509 to rotate on the surface of the positioning rod 508. When the rotation reaches the appropriate position, the second bolt 510 is manually rotated, causing it to press against one side of the rotating rod 506. This effectively confines the rotating rod 506 within the limiting frame 509. The first bolt 503 is then manually rotated, pressing against the top of the connecting rod 3. This extends the length of the connecting rod 3 to some extent, making it easier to position the connecting sleeve 1. The fourth spring 512 presses the rotating rod 506 away from the limiting frame 509, facilitating the control of the rotating rod 506 to slide out of the limiting frame 509.

[0031] It should be noted that all damping rods in this case are telescopic dampers, which can absorb energy during the extension and retraction process.
