Description

Technical Field

[0001] This invention relates to the field of chainsaw processing technology, and in particular to a high-frequency quenching device for chainsaw guide plates. Background Technology

[0002] As a key component of a chainsaw, the performance of the guide plate directly affects the chainsaw's working efficiency and service life. High-frequency quenching is a commonly used heat treatment process to improve the hardness and wear resistance of chainsaw guide plates. It involves using a high-frequency current to generate an induced current on the guide plate surface, rapidly heating the surface to the quenching temperature, followed by rapid cooling, thereby forming a high-hardness martensitic structure on the guide plate surface.

[0003] However, existing high-frequency quenching equipment for chainsaw guide plates has many problems in practical applications. Regarding guide plate clamping, traditional clamping devices struggle to achieve stable and precise clamping, causing the guide plate to easily move or deflect during heating, affecting the uniformity of heating. Furthermore, the positional alignment between the clamping device and the induction heating coil is not precise enough, failing to guarantee the guide plate's centered position within the coil. This results in inconsistent heating temperatures across different parts of the guide plate, reducing the quenching quality.

[0004] Regarding guide plate alignment, the lack of an effective alignment structure makes it difficult to accurately align the guide plate with the clamping plate before clamping, causing the guide plate to tilt or shift during clamping, further affecting the uniformity of heating. Furthermore, removing the guide plate after heating is not convenient, increasing the workload and operation time for workers.

[0005] In terms of equipment adjustment, the position adjustment of the induction heating coil and the ring support frame is not flexible enough, requiring constant manual fine-tuning, which leads to low adjustment efficiency and low quenching efficiency of the guide plate.

[0006] Therefore, developing a high-frequency quenching equipment for chainsaw guide plates that can stably and accurately clamp the guide plates, effectively align them, flexibly and precisely adjust the positions of the induction heating coil and the annular support frame, and improve quenching quality and production efficiency is of great practical significance. Summary of the Invention

[0007] The purpose of this invention is to solve the shortcomings of existing guide plates, such as uneven heating and difficulty in adjusting the position of the coil and clamping plate, and to propose a high-frequency quenching device for chainsaw guide plates.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: A high-frequency quenching device for chainsaw guide plates includes: The outer casing has a coolant tank at its top for holding coolant; a support bracket is fixed at the bottom of the coolant tank, and a mounting plate is fixed inside the support bracket. It also includes an upper clamping plate and a lower clamping plate, both of which are disposed in the coolant tank, and an induction heating coil is disposed in the coolant tank; A drive structure is provided in the coolant tank and the support bracket, which is used to drive the upper clamping plate and the lower clamping plate to cooperate to clamp the guide plate and move the guide plate into the induction heating coil for heating. The drive structure includes a hydraulic drive cylinder fixed to the top of the mounting plate and a cylindrical body fixed through the bottom inner wall of the coolant tank. A support plate is fixed to the bottom of the induction heating coil, and an annular support frame is fixed to the top of the induction heating coil. An adjustment structure is provided inside the annular support frame to adjust the position of the induction heating coil and the annular support frame so that the lower clamping plate is located at its center. The adjustment structure includes four hydraulic cylinders I fixed to the outer wall of the annular support frame, and the four hydraulic cylinders I are arranged symmetrically in pairs. An alignment structure is used to limit and align the guide plate before the upper clamping plate and the lower clamping plate clamp the guide plate. The alignment structure includes two limiting baffles II for limiting one side of the guide plate, and limiting baffles I and III for limiting the other two sides of the guide plate.

[0009] In one possible design, the drive structure includes a lifting support column slidably disposed within the cylindrical body. An elastic element I is fixed between the bottom end of the lifting support column and the bottom inner wall of the cylindrical body via a spring seat. The top end of the lifting support column is fixedly connected to the bottom of the lower clamping plate. The output shaft of the hydraulic drive cylinder passes through the mounting plate and is fixedly connected to the top of the upper clamping plate. Sliding guide rods are fixed on both sides of the top of the upper clamping plate. The top ends of the two sliding guide rods slide sequentially through the mounting plate and the support bracket. The hydraulic drive cylinder pushes the upper clamping plate downward to cooperate with the lower clamping plate to clamp the guide plate, and continues to push the lower clamping plate downward to compress the elastic element I, thereby transferring the guide plate into the induction heating coil for heating, and can further immerse the heated guide plate in the coolant for quenching.

[0010] In one possible design, the adjustment structure further includes four fluid communication pipes, with two adjacent hydraulic cylinders I being fixedly connected through the fluid communication pipes, and each of the four hydraulic cylinders I being slidably and sealed with a hydraulic rod I, one end of each of the four hydraulic rods I slidingly penetrating the annular support frame; An electric linear actuator and a hydraulic cylinder II are fixedly connected to one side of the outer casing. The hydraulic cylinder II is located above the electric linear actuator. A hydraulic rod II is slidably and sealed inside the hydraulic cylinder II. The bottom end of the hydraulic rod II extends to the bottom of the hydraulic cylinder II and is fixedly connected to the top end of the output shaft of the electric linear actuator. A liquid delivery pipe is fixed to one side of the hydraulic cylinder II. The end of the liquid delivery pipe away from the hydraulic cylinder II is fixedly connected to the adjacent hydraulic cylinder I. The electric linear actuator pushes the hydraulic rod II upward, injecting hydraulic oil into the hydraulic cylinder I through the fluid delivery pipe and the fluid communication pipe. This drives the four hydraulic rods I to move towards each other and abut against the outer wall of the lower clamping plate, thereby adjusting the position of the annular support frame, the induction heating coil, and the bearing working plate, so that the lower clamping plate is located in the center.

[0011] In one possible design, the adjustment structure further includes two U-shaped structural plates fixed to the inner wall of the bottom of the coolant tank, and two movable guide grooves are provided in the bearing working plate. The two U-shaped structural plates pass through the corresponding movable guide grooves and slide with them. The top inner walls of both movable guide grooves are slidably penetrated by lifting movable plates, the bottom ends of both lifting movable plates are fixed with extrusion plates, the top ends of both lifting movable plates are sealed and slidably extended into the corresponding hydraulic cylinder I, both lifting movable plates are provided with inclined guide grooves, both inclined guide grooves are slidably provided with positioning pins, both ends of both positioning pins are fixed with two rotating lugs, and the two rotating lugs are fixed to one end of the corresponding hydraulic cylinder I; The electric linear actuator pulls the hydraulic rod II downward to draw hydraulic oil, causing the hydraulic rod I to move outward. Through the cooperation of the positioning pin and the inclined guide groove, the lifting movable plate is driven to move downward, thereby causing the pressing plate to press the U-shaped structural plate to fix the bearing working plate.

[0012] In one possible design, the alignment structure further includes two U-shaped structural frames that slide through the mounting plate. The top inner walls of the two U-shaped structural frames are each fixed with multiple elastic elements II by spring seats. The bottom ends of the multiple elastic elements II are fixedly connected to the top of the mounting plate by spring seats. The tops of the two limiting baffles II are respectively fixed to the bottom ends of the two U-shaped structural frames. Two transverse connecting plates are fixed on one side of the two U-shaped structural frames that are close to each other. One of the transverse connecting plates is fixed with a middle connecting plate on one side. A vertical support plate that slides through the mounting plate is fixed to the bottom of the middle connecting plate. The bottom of the vertical support plate is fixedly connected to the top of the limiting baffle III. The top of the upper clamping plate is fixed with two fixed connecting rods, the top ends of the two fixed connecting rods slide through the mounting plate and are fixed with permanent magnets, and the bottom of the two transverse connecting plates is fixed with sheet metal layers. When the upper clamping plate moves downward, the magnetic attraction between the permanent magnet and the iron sheet layer drives the horizontal connecting plate and the vertical support plate to move downward synchronously, so that the limiting baffle III, the limiting baffle I and the two limiting baffles II together limit and align the guide plate.

[0013] In one possible design, a fixed connecting block is fixed to the bottom of the mounting plate, and an arc-shaped connecting rod slides through the fixed connecting block. The bottom end of the arc-shaped connecting rod is fixedly connected to one side of the limiting baffle I, and an inclined support rod is fixed to the top end of the arc-shaped connecting rod. The inclined support rod cooperates with the top of the upper clamping plate. The outer wall of the inclined support rod is fixedly fitted with a load-bearing ball, and the outer wall of the arc-shaped connecting rod is fixedly fitted with a limiting ring, which is located below the fixed connecting block; When the upper clamping plate moves upward, it pushes the inclined support rod, drives the arc-shaped connecting rod to rotate, and pushes the guide plate away through the limiting baffle I, making it easier to remove the part. The load-bearing ball is used to reset the inclined support rod after the thrust is lost.

[0014] In one possible design, the shapes of the upper clamping plate and the lower clamping plate are adapted to the shape of the guide plate to be processed, so as to uniformly clamp the guide plate and make the guide plate uniformly heated in the induction heating coil.

[0015] In one possible design, the induction heating coil has the same shape as the annular support frame. When the annular support frame clamps and limits the lower clamping plate through the hydraulic rod I, it can simultaneously center and align the induction heating coil with the upper clamping plate.

[0016] In one possible design, both the limiting baffle III and the limiting baffle II are provided with guide slopes on the side near the lower clamping plate.

[0017] In one possible design, the inner walls of the two opposite sides of the annular support frame are provided with storage grooves I, and the inner walls of the other two sides are provided with storage grooves II. An arc-shaped clamping plate I is slidably fitted in the storage groove I, and an arc-shaped clamping plate II is slidably fitted in the storage groove II. The side of the arc-shaped clamping plate I and the arc-shaped clamping plate II away from the lower clamping plate is fixedly connected to one end of the adjacent hydraulic rod I. Both the arc-shaped clamping plate II and the arc-shaped clamping plate I have multiple rolling wheels rotatably mounted on the side closest to the lower clamping plate. The rollers are used to reduce friction for precise alignment.

[0018] Beneficial effects: In this invention, two adjacent hydraulic cylinders I are fixedly connected by a fluid communication pipe. Each of the four hydraulic cylinders I has a hydraulic rod I that slides through it in a sealed manner. Each hydraulic cylinder II has a hydraulic rod II that slides through it in a sealed manner and is fixedly connected to the output shaft of an electric linear actuator. The hydraulic cylinder II is fixedly connected to the adjacent hydraulic cylinder I through a fluid delivery pipe. The output shaft of the electric linear actuator pushes the hydraulic rod II upwards, injecting hydraulic oil into the four hydraulic cylinders I. The four hydraulic rods I move towards the center to abut against the outer wall of the lower clamping plate. Therefore, the positions of the annular support frame, the induction heating coil, and the bearing working plate can be adjusted, ensuring that the lower clamping plate is located at the center of the annular support frame and the induction heating coil. This facilitates the subsequent centered heating of the guide plate by the induction heating coil, ensuring uniform heating. In this invention, the two U-shaped structural plates are respectively slidably fitted with corresponding sliding plates. A lifting movable plate slides through the top inner wall of each of the two movable guide grooves. A pressing plate is fixed to the bottom end of each of the two lifting movable plates. An inclined guide groove is provided inside each of the two lifting movable plates. A positioning pin is slidably provided inside each of the two inclined guide grooves. Two rotating lugs are fixed to both ends of each of the two positioning pins. The output shaft of the electric linear push rod drives the hydraulic rod II downwards, drawing hydraulic oil into the hydraulic cylinder II. The hydraulic rod I moves outwards. The hydraulic rod I drives the lifting movable plate downwards through the cooperation of the positioning pin and the inclined guide groove. The lifting movable plate presses the U-shaped structural plate through the pressing plate, completing the fixation between the bearing working plate and the U-shaped structural plate. This facilitates the subsequent centered heating of the guide plate by the induction heating coil, ensuring uniform heating. In this invention, two U-shaped structural frames slide through the mounting plate. Two horizontal connecting plates are fixed to one side of the two U-shaped structural frames that are close to each other. A vertical support plate is fixed to one side of one of the horizontal connecting plates through a middle connecting plate. Two permanent magnets are fixed to the top of the upper clamping plate through a fixed connecting rod. A sheet metal layer is fixed to the bottom of both horizontal connecting plates. The upper clamping plate moves the horizontal connecting plate and the vertical support plate downward synchronously through the magnetic attraction between the permanent magnets and the sheet metal layer at the bottom of the horizontal connecting plates. Limiting baffles III, I, and two II can limit the guide plate in four directions, thereby regulating the position of the guide plate, making the guide plate and the lower clamping plate accurately overlap, and making the distance between the different positions of the edge of the guide plate and the inner wall of the induction heating coil the same, ensuring the uniformity of the guide plate during subsequent heating. In this invention, an arc-shaped connecting rod slides through the fixed connecting block. The bottom end of the arc-shaped connecting rod is fixedly connected to one side of the limiting baffle I. An inclined support rod is fixedly attached to the top end of the arc-shaped connecting rod. A load-bearing ball is fixedly sleeved on the outer wall of the inclined support rod. The inclined support rod cooperates with the top of the upper clamping plate and is used to move up on the upper clamping plate and drive the arc-shaped connecting rod to rotate through the inclined support rod. It can push the guide plate to one side through the limiting baffle I, making it easier for the staff to remove the guide plate. The load-bearing ball can reset the inclined support rod after it loses the push from the upper clamping plate, which is convenient for it to cooperate with the limiting baffle II and the limiting baffle III to limit and align the guide plate in the later stage.

[0019] In this invention, the position of the annular support frame can be precisely adjusted to center the lower clamping plate, ensuring that the guide plate is uniformly heated within the induction heating coil. The position of the guide plate is also regulated to ensure precise overlap with the lower clamping plate, guaranteeing uniform heating, facilitating guide plate removal, improving operational convenience, and allowing for flexible adaptation to guide plates of different specifications. Through the cooperation of various components, the clamping, heating, cooling, and quenching processes are completed efficiently, improving production efficiency and product quality, and providing strong support for chainsaw guide plate production.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0023] In one embodiment: Refer to Figure 1 and Figure 2This high-frequency quenching equipment relates to the field of saw chain processing technology. It mainly includes an outer casing 1, made of high-strength metal material, which provides excellent protection and structural stability, effectively protecting the internal equipment from external environmental influences. The top of the outer casing 1 is equipped with a coolant tank 2 for holding coolant. The volume of the coolant tank 2 is designed according to the actual processing capacity and operational requirements of the equipment, generally holding a sufficient amount of coolant to ensure adequate cooling during the guide plate quenching process. A support bracket 3 is fixed to the bottom inner wall of the coolant tank 2. The support bracket 3 adopts a robust metal frame structure, providing stable support for other components of the equipment. A mounting plate 4 is fixed inside the support bracket 3. The mounting plate 4 is made of high-strength, corrosion-resistant metal sheet and is used to install and fix the drive structure and other components of the equipment.

[0024] Reference Figure 2 and Figure 3 The coolant tank 2 is equipped with an upper clamping plate 6 and a lower clamping plate 11. The shapes of the upper clamping plate 6 and the lower clamping plate 11 are the same as those of the guide plate. This design can better fit the guide plate, achieve stable clamping of the guide plate, and ensure uniform heating of the guide plate within the induction heating coil 15. Both the upper clamping plate 6 and the lower clamping plate 11 are made of high-temperature resistant and high-strength alloy materials, which can withstand the high temperature and mechanical stress during the high-frequency quenching process.

[0025] Reference Figure 2 and Figure 3 To enable the upper clamping plate 6 and lower clamping plate 11 to cooperate in clamping the guide plate and moving it into the induction heating coil 15 for heating, a driving structure is provided within the coolant tank 2 and the support bracket 3. The driving structure includes a hydraulic drive cylinder 5 fixed to the top of the mounting plate 4 and a cylindrical body 8 fixedly penetrating the inner wall of the bottom of the coolant tank 2. The hydraulic drive cylinder 5 is a high-performance hydraulic cylinder, whose output force and stroke meet the equipment's driving requirements for the upper clamping plate 6. The output shaft of the hydraulic drive cylinder 5 passes through the mounting plate 4 and is fixedly connected to the top of the upper clamping plate 6. Sliding guide rods 7 are fixed on both sides of the top of the upper clamping plate 6, and the top ends of the two sliding guide rods 7 slide sequentially through the mounting plate 4 and the support bracket 3. The sliding guide rods 7 are made of high-precision, wear-resistant metal material, and their surfaces are smoothed to reduce friction during sliding, ensuring that the upper clamping plate 6 can move smoothly and accurately up and down under the drive of the hydraulic drive cylinder 5.

[0026] Reference Figure 2 and Figure 3 The drive structure also includes a lifting support column 9 that slides inside the cylindrical body 8. An elastic element I10, a tension spring, is fixed between the bottom end of the lifting support column 9 and the inner bottom wall of the cylindrical body 8 via a spring seat. The top end of the lifting support column 9 is fixedly connected to the bottom of the lower clamping plate 11.

[0027] During operation, the hydraulic drive cylinder 5 pushes the upper clamping plate 6 downwards, which, together with the lower clamping plate 11, clamps the guide plate. As the hydraulic drive cylinder 5 continues to push the upper clamping plate 6 downwards, the upper clamping plate 6 pushes the lower clamping plate 11 downwards via the guide plate. The lower clamping plate 11 then compresses the elastic element I10, causing it to deform elastically. When the guide plate is clamped and moved into the induction heating coil 15, the induction heating coil 15 is energized, generating a high-frequency magnetic field that rapidly heats the surface of the guide plate to the quenching temperature. After heating, the hydraulic drive cylinder 5 continues to push the upper clamping plate 6 and the lower clamping plate 11 downwards, immersing the heated guide plate in the coolant for cooling and quenching. After quenching, the hydraulic drive cylinder 5 pulls the upper clamping plate 6 upwards, causing the elastic element I10 to recover its elastic deformation and push the lower clamping plate 11 upwards, facilitating the removal of the guide plate.

[0028] Reference Figures 2-5 The coolant tank 2 is also equipped with an induction heating coil 15, which is made of a highly conductive metal material. The number of turns and dimensions are designed according to the specifications of the guide plate and the heating requirements. A supporting working plate 13 is fixed to the bottom of the induction heating coil 15. The supporting working plate 13 is made of high-temperature resistant, high-strength ceramic material, capable of withstanding high temperatures and mechanical stress, providing stable support for the induction heating coil 15. An annular support frame 16 is fixed to the top of the induction heating coil 15. The induction heating coil 15 and the annular support frame 16 have the same shape. This design facilitates simultaneous centering of the induction heating coil 15 with the upper clamping plate 6 when the annular support frame 16 clamps and limits the lower clamping plate 11 via the hydraulic rod I 18, ensuring the guide plate is centered within the induction heating coil 15 and improving heating uniformity.

[0029] Reference Figure 2 , Figure 4 and Figure 5To ensure that the lower clamping plate 11 is positioned and centered within the induction heating coil 15, an adjustment structure is provided within the annular support frame 16. This adjustment structure includes four hydraulic cylinders I 17 fixed to the outer wall of the annular support frame 16, arranged in pairs, with the two cylinders in each pair placed symmetrically. Each of the four hydraulic cylinders I 17 has a hydraulic rod I 18 that slides through it in a sealed manner, with one end of each hydraulic rod I 18 sliding through the annular support frame 16. The four hydraulic cylinders I 17 are fixedly connected to each other via a fluid connecting pipe 19, which is made of high-strength, corrosion-resistant metal to ensure smooth flow of hydraulic oil between the cylinders I 17. An electric linear actuator 23 and a hydraulic cylinder II 21 are fixedly connected to one side of the outer casing 1, with the hydraulic cylinder II 21 positioned above the electric linear actuator 23. A hydraulic rod II22 is slidably passed through the inner seal of hydraulic cylinder II21, and the bottom end of hydraulic rod II22 extends to the bottom of hydraulic cylinder II21 and is fixedly connected to the top of the output shaft of electric linear actuator 23. A liquid delivery pipe 20 is fixed to one side of hydraulic cylinder II21, and the end of liquid delivery pipe 20 away from hydraulic cylinder II21 is fixedly connected to the adjacent hydraulic cylinder I17.

[0030] Reference Figure 2 , Figure 4 , Figure 6 and Figure 7 The adjustment structure also includes two U-shaped structural plates 12 fixed to the inner wall of the bottom of the coolant tank 2. Two movable guide grooves 14 are provided within the bearing working plate 13. The two U-shaped structural plates 12 pass through the corresponding movable guide grooves 14 and slide in cooperation with them. Lifting movable plates 25 slide through the inner top walls of both movable guide grooves 14. A pressing plate 24 is fixed to the bottom end of each of the two lifting movable plates 25, and the pressing plate 24 cooperates with the U-shaped structural plates 12. The top ends of both lifting movable plates 25 extend in a sealed sliding manner into the corresponding hydraulic cylinder I 17. Inclined guide grooves 26 are provided within each of the two lifting movable plates 25, and the inclined guide grooves 26 are located within the hydraulic cylinder I 17. Positioning pins 27 slide within each of the two inclined guide grooves 26. Two rotating lugs 28 are fixed to both ends of each positioning pin 27, and the two rotating lugs 28 are fixed to one end of the corresponding hydraulic rod I 18.

[0031] During operation, when the positions of the induction heating coil 15 and the annular support frame 16 need to be adjusted, the output shaft of the electric linear actuator 23 pushes the hydraulic rod II 22 upward. The hydraulic rod II 22 injects the hydraulic oil in the hydraulic cylinder II 21 into the four hydraulic cylinders I 17 through the fluid delivery pipe 20 and the cooperation of multiple fluid connecting pipes 19. Under the action of the hydraulic oil, the four hydraulic rods I 18 move towards the center, and the four hydraulic rods I 18 abut against the outer wall of the lower clamping plate 11, and the pressing force of the four hydraulic rods I 18 on the lower clamping plate 11 is the same. Since the position of the lower clamping plate 11 is fixed, when the hydraulic rods I 18 abut against the lower clamping plate 11, the positions of the annular support frame 16, the induction heating coil 15, and the supporting working plate 13 can be adjusted so that the lower clamping plate 11 is located at the center position of the annular support frame 16 and the induction heating coil 15, thus initially completing the adjustment of the position of the induction heating coil 15.

[0032] When it is necessary to fix the position between the bearing working plate 13 and the U-shaped structural plate 12, the output shaft of the electric linear actuator 23 drives the hydraulic rod II 22 to move downward, drawing hydraulic oil into the hydraulic cylinder II 21, and the hydraulic rod I 18 moves outward. The hydraulic rod I 18 drives the lifting movable plate 25 to move downward through the cooperation of the positioning pin 27 and the inclined guide groove 26. The lifting movable plate 25 presses the U-shaped structural plate 12 through the pressing plate 24, completing the fixation between the bearing working plate 13 and the U-shaped structural plate 12, which facilitates the subsequent centering heating of the guide plate by the induction heating coil 15 and ensures the uniformity of heating.

[0033] Reference Figure 8 and Figure 10 The device also includes an alignment structure, which is used to align and overlap the guide plate with the lower clamping plate 11 before the upper clamping plate 6 and the lower clamping plate 11 complete clamping of the guide plate. The alignment structure includes a limiting baffle II 35 that limits one side of the guide plate, and a limiting baffle I 33 and a limiting baffle III 40 that limit the other two sides of the guide plate.

[0034] Reference Figure 8 and Figure 10The alignment structure also includes two U-shaped structural frames 34 that slide through the mounting plate 4. Multiple elastic elements II 36 are fixed to the top inner walls of both U-shaped structural frames 34 via spring seats. The elastic elements II 36 are tension springs with an elastic coefficient ranging from 30 N / mm to 80 N / mm. The initial tension length is set according to the actual requirements of the equipment, typically from 5 mm to 20 mm. The bottom ends of the multiple elastic elements II 36 are fixedly connected to the top of the mounting plate 4 via spring seats. The tops of the two limiting baffles II 35 are respectively fixed to the bottom ends of the two U-shaped structural frames 34. Two transverse connecting plates 37 are fixed to the side of the two U-shaped structural frames 34 that are close to each other. One of the transverse connecting plates 37 has a middle connecting plate 38 fixed to one side. The bottom end of the middle connecting plate 38 is fixed to a vertical support plate 39 that slides through the mounting plate 4. The bottom end of the vertical support plate 39 is fixedly connected to the top of the limiting baffle III 40.

[0035] Reference Figure 8 and Figure 10 Two fixed connecting rods 41 are fixed to the top of the upper clamping plate 6. The top ends of the two fixed connecting rods 41 slide through the mounting plate 4 and are fixed with permanent magnets 42. The bottom of the two transverse connecting plates 37 are fixed with sheet metal layers. The limiting baffles III 40 and II 35 are provided with inclined surfaces on the side near the lower clamping plate 11. These surfaces are used to guide the guide plate when the limiting baffles III 40 and II 35 move downward, so as to facilitate the limiting and alignment of the guide plate.

[0036] During operation, the upper clamping plate 6 moves the permanent magnet 42 downward via the fixed connecting rod 41. The magnetic attraction between the permanent magnet 42 and the sheet metal layer at the bottom of the horizontal connecting plate 37 causes the horizontal connecting plate 37 and the vertical support plate 39 to move downward synchronously. The limiting baffles III 40, I 33, and two II 35 can limit the guide plate in four directions, thereby regulating the position of the guide plate and ensuring that the guide plate and the lower clamping plate 11 are precisely overlapped. This ensures that the different positions of the edge of the guide plate are at the same distance from the inner wall of the induction heating coil 15, guaranteeing the uniformity of the guide plate during subsequent heating.

[0037] Reference Figure 8 and Figure 9A fixed connecting block 29 is fixed to the bottom of the mounting plate 4. An arc-shaped connecting rod 30 slides through the fixed connecting block 29. The bottom end of the arc-shaped connecting rod 30 is fixedly connected to one side of the limiting baffle I 33. An inclined support rod 31 is fixed to the top of the arc-shaped connecting rod 30, and the inclined support rod 31 cooperates with the top of the upper clamping plate 6. A load-bearing ball 32 is fixedly sleeved on the outer wall of the inclined support rod 31 to reset the inclined support rod 31 after it loses the push of the upper clamping plate 6. A limiting ring is fixedly sleeved on the outer wall of the arc-shaped connecting rod 30, and the limiting ring is located below the fixed connecting block 29 to limit the arc-shaped connecting rod 30 when it resets, so that it can cooperate with the limiting baffle II 35 and the limiting baffle III 40 to limit and align the guide plate later.

[0038] When the guide plate needs to be removed, the upper clamping plate 6 moves upward and drives the arc-shaped connecting rod 30 to rotate through the inclined support rod 31. The arc-shaped connecting rod 30 drives the limiting baffle I 33 to push the guide plate to one side, making it easier for the staff to remove the guide plate and improving the convenience of operation.

[0039] In another embodiment: Refer to Figure 11 To further precisely adjust the position of the annular support frame 16, two inner walls on opposite sides of the annular support frame 16 are provided with storage grooves I 43, and two inner walls on the other opposite sides of the annular support frame 16 are provided with storage grooves II 45. An arc-shaped clamping plate I 44 slides within the storage groove I 43, and an arc-shaped clamping plate II 46 slides within the storage groove II 45. The sides of the arc-shaped clamping plates I 44 and II 46 furthest from the lower clamping plate 11 are fixedly connected to one end of an adjacent hydraulic rod I 18. Multiple rolling wheels 47 are rotatably mounted on the sides of the arc-shaped clamping plates II 46 and I 44 closest to the lower clamping plate 11. The rolling wheels 47 are made of high-strength, wear-resistant metal material, which reduces the friction between the arc-shaped clamping plates I 44 and II 46 and the outer wall of the lower clamping plate 11.

[0040] When the four hydraulic rods I18 move towards the center to clamp and abut against the lower clamping plate 11, the cooperation of the arc-shaped clamping plate II46 and arc-shaped clamping plate I44 makes it easier to center and align the annular support frame 16 with the lower clamping plate 11. Furthermore, the multiple rolling wheels 47 provided on one side of the arc-shaped clamping plate II46 and arc-shaped clamping plate I44 can further reduce the friction between the arc-shaped clamping plate I44, arc-shaped clamping plate II46 and the outer wall of the lower clamping plate 11, thereby improving the flexibility and accuracy of adjustment.

[0041] A method for using a high-frequency quenching device for chainsaw guide plates includes the following steps: S1. Before heating the guide plate, the induction heating coil 15 needs to be installed, and the induction heating coil 15 needs to be aligned with the upper clamping plate 6 and the lower clamping plate 11 to facilitate the guide plate being centered on the induction heating coil 15 later. Specifically, the output shaft of the hydraulic drive cylinder 5 pushes the upper clamping plate 6 downward, and the upper clamping plate 6 pushes the lower clamping plate 11 downward into the annular support frame 16. Then, the output shaft of the electric linear push rod 23 pushes the hydraulic rod II 22 upward. The hydraulic rod II 22 injects the hydraulic oil in the hydraulic cylinder II 21 into the four hydraulic cylinders I 17 through the fluid delivery pipe 20 and the cooperation of multiple fluid connecting pipes 19. Under the action of the hydraulic oil, the four hydraulic rods I 18 move towards the center and abut against the outer wall of the lower clamping plate 11. The four hydraulic rods I 18 exert the same pressure on the lower clamping plate 11. With the holding plate 11 fixed in position, when the hydraulic rod I 18 abuts against the lower clamping plate 11, the positions of the annular support frame 16, the induction heating coil 15, and the bearing working plate 13 can be adjusted, so that the lower clamping plate 11 is located at the center of the annular support frame 16 and the induction heating coil 15, and the position of the induction heating coil 15 is initially adjusted. Then, the output shaft of the electric linear push rod 23 drives the hydraulic rod II 22 to move down, drawing hydraulic oil into the hydraulic cylinder II 21. The hydraulic rod I 18 moves outward, and the hydraulic rod I 18 drives the lifting movable plate 25 to move down through the cooperation of the positioning pin rod 27 and the inclined guide groove 26. The lifting movable plate 25 presses the U-shaped structure plate 12 through the pressing action plate 24, completing the fixation between the bearing working plate 13 and the U-shaped structure plate 12, which facilitates the subsequent centered heating of the guide plate in the induction heating coil 15 and ensures the uniformity of heating. S2. When the four hydraulic rods I18 move towards the center to clamp and abut against the lower clamping plate 11, the cooperation of the arc-shaped clamping plate II46 and the arc-shaped clamping plate I44 makes it easier to center and align the ring support frame 16 with the lower clamping plate 11. The multiple rolling wheels 47 provided on one side of the arc-shaped clamping plate II46 and the arc-shaped clamping plate I44 can reduce the friction between the arc-shaped clamping plate I44, the arc-shaped clamping plate II46 and the outer wall of the lower clamping plate 11. S3. Place the guide plate to be quenched on the lower clamping plate 11, and limit baffle I 33 limits one end of the guide plate. Then, the hydraulic drive cylinder 5 pushes the upper clamping plate 6 downward. The upper clamping plate 6 drives the permanent magnet 42 downward through the fixed connecting rod 41. The magnetic attraction between the permanent magnet 42 and the iron sheet layer at the bottom of the horizontal connecting plate 37 drives the horizontal connecting plate 37 and the vertical support plate 39 to move downward synchronously. Limit baffle III 40, limit baffle I 33 and two limit baffles II 35 can limit the guide plate in four directions, thereby regulating the position of the guide plate and making the guide plate and the lower clamping plate 11 accurately overlap, so that the different positions of the edge of the guide plate are aligned. The distance from the inner wall of the induction heating coil 15 is the same to ensure the uniformity of the guide plate heating in the later stage. The hydraulic drive cylinder 5 continues to push the upper clamping plate 6 to move down. The upper clamping plate 6 and the lower clamping plate 11 cooperate to clamp the guide plate. When the upper clamping plate 6 pushes the lower clamping plate 11 and the guide plate to move down and extend into the induction heating coil 15, the lower clamping plate 11 compresses the elastic element I 10 through the lifting support column 9. At this time, the fixed connecting rod 41 is located below the mounting plate 4. The permanent magnet 42 and the iron sheet layer at the bottom of the horizontal connecting plate 37 are disengaged from the magnetic attraction. The U-shaped structure frame 34 and the vertical support plate 39 move up and reset under the action of the elastic element II 36. S4. When the upper clamping plate 6 and the lower clamping plate 11 move the clamped guide plate into the induction heating coil 15, the induction heating coil 15 is energized to heat the guide plate. Then, the hydraulic drive cylinder 5 pushes the lower clamping plate 11 and the heated guide plate downwards, immersing them in the coolant in the coolant tank 2 to cool the guide plate. The hydraulic drive cylinder 5 then drives the upper clamping plate 6, the lower clamping plate 11, and the cooled guide plate upwards to reset. At this time, the lower clamping plate 11 resets to its initial position under the elastic force of the cylindrical body 8. The height is adjusted, and the limiting baffle I33 touches one end of the guide plate. After the hydraulic drive cylinder 5 moves the upper clamping plate 6 upward, it releases the clamping of the guide plate from the lower clamping plate 11 and continues to move upward. The upper clamping plate 6 drives the arc-shaped connecting rod 30 to slide within the fixed connecting block 29 through the inclined support rod 31. Then, through the cooperation of the arc-shaped connecting rod 30 and the limiting baffle I33, the guide plate is pushed to one side, and one end of the guide plate protrudes from the lower clamping plate 11, making it easy for the staff to take out the quenched guide plate with pliers.
