Description

Technical Field

[0001] The invention belongs to the technical field of diaphragm spring processing, in particular to a quenching processing device for an automobile diaphragm spring. Background Art

[0002] The automotive diaphragm spring is a special structural spring made of spring steel, mainly composed of a disc spring part and a separation finger part. It is often used in automobile clutch and suspension systems to play the role of shock absorption, buffering and support. The automotive diaphragm spring quenching processing equipment is a device specially used for quenching automobile diaphragm springs. By precisely controlling the heating and cooling process, the mechanical properties of the diaphragm spring can be improved, such as increasing hardness and strength, thereby ensuring the safety and reliability of the vehicle.

[0003] In the existing technology, automotive diaphragm spring quenching processing equipment uses a heating device such as a high-frequency induction heater to heat the diaphragm spring to a certain temperature (such as 900°C to 920°C), and then quickly immerses it in a quenching medium (such as water or oil) for rapid cooling, thereby changing the internal structure of the metal, increasing the hardness and strength of the diaphragm spring, and achieving the purpose of improving its mechanical properties.

[0004] There are still some problems in the actual application of the above scheme. When quenching the separation fingers in the automobile diaphragm spring, all the separation fingers in the diaphragm spring need to be fitted on the heating ring. However, due to machine failure during the loading process, the separation fingers and the heating ring in the automobile diaphragm will be offset. This will make the heat originally evenly distributed on the automobile diaphragm separation fingers become uneven, which will cause some parts of the automobile diaphragm separation fingers to overheat, while other parts will not have enough temperature, thereby affecting the heating effect and product quality. Secondly, when positioning the automobile diaphragm through the added downward pressure leveling mechanism, due to the high hardness and sharp edges of the automobile diaphragm separation fingers, the surface of the heating ring will be worn during the positioning process, which will cause uneven heat transfer and reduce heating efficiency. The worn parts will form thermal resistance, which will hinder the effective transfer of heat, thereby reducing the heating effect of the automobile diaphragm separation fingers.

[0005] To this end, the present invention provides a quenching processing equipment for automobile diaphragm springs. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

A telescopic column is slidably connected inside the cylinder, and a first fixed plate is fixedly connected to the top of the telescopic column.

[0011] Preferably, the cylinder and the telescopic column cooperate to drive the leveling circular plate to perform reciprocating motion. A protrusion that is compatible with the groove on the outer annular surface of the displacement rod is provided inside the second rotating disk. When the second rotating disk rotates, it can drive the displacement rod to rotate, thereby driving the leveling circular plate to rotate, thereby improving the smoothing work efficiency, and at the same time improving the uniformity of the automobile diaphragm separation finger during heating.

[0013] Preferably, the provision of the pulley can reduce the wear of the lifting limit mechanism during the movement of the downward pressure leveling mechanism, thereby increasing the service life of the entire device.

[0014] Preferably, the bottom of the first sliding column is fixedly connected to a first spring, the bottom of the first spring is fixedly connected to the bottom of the inner cavity of the fixed cylinder, the other end of the fixed cylinder is slidably connected to the inside of the second sliding column, the bottom of the second sliding column is fixedly connected to the second spring, the bottom of the second spring is fixedly connected to the inner cavity of the fixed cylinder, the upper part of the second sliding column is fixedly connected to a moving ring, and the upper part of the moving ring is rotatably connected to a rotating ball close to the inner ring surface.

[0015] Preferably, the lifting of the movable ring can avoid damage to the heating ring by the automobile diaphragm separation finger during smoothing, thereby further improving the heating effect of the automobile diaphragm separation finger.

[0017] Preferably, the engagement of the buckle can prevent the automobile diaphragm from being offset when the device is rotated, thereby improving the uniformity of heating.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The quenching processing equipment for an automobile diaphragm spring described in the present invention drives the leveling circular plate to move synchronously when the displacement rod moves downward. When the bottom of the leveling circular plate contacts the upper part of the automobile diaphragm, the leveling circular plate will continue to press down and, while pressing down, start the driving motor. Since the output shaft of the driving motor is fixed to the first rotating disk, the first rotating disk will rotate synchronously when the driving motor is started, and at the same time drive the second belt on its outer ring surface to transmit, and synchronously drive the second rotating disk to rotate. Since the interior of the second rotating disk is provided with a protrusion that is adapted to the groove on the outer ring surface of the displacement rod, and the displacement rod rotates at the bottom of the first fixed plate, the displacement rod will be driven to rotate synchronously when the second rotating disk rotates, and the leveling circular plate fixed at the bottom of the displacement rod will also be driven to rotate synchronously.

[0020] 2. The automobile diaphragm spring quenching processing equipment described in the present invention, when the leveling circular plate is pressed down, the first sliding column is squeezed to move downward along the guide of the fixed cylinder, and the fixed cylinder at the bottom is squeezed while moving. At the same time, since the fixed cylinder is a "U"-shaped column and contains a liquid medium, when the first sliding column moves downward, the liquid medium inside the fixed cylinder is pushed to the other side, and at the same time, the second sliding column is pushed upward to synchronously drive the moving ring and the rotating ball to move synchronously. The setting of the rotating ball can facilitate the leveling of the automobile diaphragm on the moving ring, and at the same time, pushing the automobile diaphragm away from the heating ring can avoid direct contact with the heating ring, thereby avoiding wear or scratches on the surface of the heating ring during the leveling process, thereby protecting the integrity of the heating ring.

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods. Example 1

[0035] like Figures 1 to 8 As shown, an automotive diaphragm spring quenching processing equipment according to an embodiment of the present invention includes a workbench 1, a quenching device 2 is provided on the upper portion of the workbench 1, and the quenching device 2 includes a drive disk 201, the outer ring surface of the drive disk 201 is drivingly connected to a first belt 202, and the inner side of the first belt 202 is rotatably connected to a limit disk 203, a water frame 204 is fixedly connected to the side of the workbench 1, a heating ring 205 is fixedly provided on the upper portion of the workbench 1, and the heating ring 205 is located at the central axis position of the water frame 204, and a downward pressure leveling mechanism 3 is provided on the side of the workbench 1;

[0036] The downward pressure leveling mechanism 3 includes an L-shaped support plate 301 fixed to the side of the workbench 1. A leveling circular plate 310 is slidingly provided on the side of the L-shaped support plate 301. The reciprocating movement of the leveling circular plate 310 can level the automobile diaphragm, thereby improving the uniformity of heating of the automobile diaphragm separation finger.

[0037] Specifically, when quenching the separation fingers in the automobile diaphragm spring, since all the separation fingers in the diaphragm spring need to be attached to the heating ring 205, a machine malfunction during the loading process may cause the separation fingers in the automobile diaphragm to be offset from the heating ring 205. This will cause the heat originally evenly distributed on the automobile diaphragm separation fingers to become uneven, causing some parts of the automobile diaphragm separation fingers to be overheated while other parts are underheated, thereby affecting the heating effect and product quality.

[0038] Therefore, the present invention solves this problem by setting a corresponding structure. The automobile diaphragm spring quenching processing equipment described in the present invention, when it is necessary to quench the separation finger in the automobile diaphragm, first place the automobile diaphragm in the limit plate 203 on the upper part of the workbench 1, then start the heating ring 205 for heating, and start the driving disk 201 to rotate while starting the heating ring 205. While rotating, the first belt 202 on its outer ring surface will be transmitted, and at the same time, the limit plate 203 will be driven to rotate. Since the automobile diaphragm is placed on the limit plate 203, the limit plate 203 will drive the automobile diaphragm to move synchronously when it rotates. When the separation finger in the automobile diaphragm is heated to a predetermined temperature, the automobile diaphragm is taken out manually or by equipment. And put it into the water frame 204 on the side of the workbench 1. Since there is a cooling medium in the water frame 204, the automobile diaphragm will cool down when it contacts the cooling medium, thereby achieving the effect of cooling the automobile diaphragm separation finger. However, due to a machine failure during the loading process, the separation finger and the heating ring 205 in the automobile diaphragm will be offset. This will make the heat originally evenly distributed on the automobile diaphragm separation finger become uneven, which will cause some parts of the automobile diaphragm separation finger to overheat, while other parts will not have enough temperature, thereby affecting the heating effect and product quality. At this time, the automobile diaphragm can be leveled during the pressing process by sliding the leveling circular plate 310 on the side of the L-shaped support plate 301, thereby improving the uniformity of heating the automobile diaphragm separation finger. Example 2

[0039] like Figures 2 to 8 As shown in Comparative Example 1, another embodiment of the present invention is:

[0040] like Figure 3 As shown, in this embodiment, the top of the L-shaped support plate 301 is fixedly connected with a cylinder 302, and the L-shaped support plate 301 is composed of a vertical plate and a horizontal plate. The inside of the cylinder 302 is slidably connected with a telescopic column 303, and the top of the telescopic column 303 is fixedly connected with a first fixed plate 304, and the lower part of the first fixed plate 304 away from the telescopic column 303 is rotatably connected with a displacement rod 305.

[0041] Specifically, when the automobile diaphragm is heated, the cylinder 302 is started, and the cylinder 302 pushes the telescopic column 303 to move downward, and simultaneously pulls the first fixed plate 304 fixed on its top to move synchronously. When the first fixed plate 304 moves, the displacement rod 305 on the lower surface of the other side of the first fixed plate 304 is driven to move synchronously. The downward pressure of the displacement rod 305 can provide corresponding power support for subsequent components.

[0042] like Figure 3 and Figure 4As shown, the downward pressure leveling mechanism 3 described in this embodiment also includes a driving motor 306, and the driving motor 306 is fixedly arranged below the horizontal plate of the L-shaped support plate 301. The output shaft of the driving motor 306 is fixedly connected to the first rotating disk 307, and the output shaft of the driving motor 306 passes through the horizontal plate of the L-shaped support plate 301. The outer ring surface of the first rotating disk 307 is transmission-connected to the second belt 308, and the inner side of the second belt 308 is rotationally connected to the second rotating disk 309, and the bottom of the displacement rod 305 is fixedly connected to the leveling circular plate 310.

[0043] Specifically, since the bottom of the displacement rod 305 and the upper part of the leveling circular plate 310 are fixed, the displacement rod 305 will drive the leveling circular plate 310 to move synchronously when it moves downward. When the bottom of the leveling circular plate 310 contacts the upper part of the automobile diaphragm, the leveling circular plate 310 will continue to press down, and at the same time, the driving motor 306 will be started. Since the output shaft of the driving motor 306 and the first rotating disk 307 are fixed, the first rotating disk 307 will rotate synchronously when the driving motor 306 is started, and at the same time, it will drive the second belt 308 on its outer ring surface to transmit, which will synchronously drive the second rotating disk 307. The moving disk 309 rotates. Since the interior of the second rotating disk 309 is provided with a protrusion that is compatible with the groove on the outer annular surface of the displacement rod 305, and the displacement rod 305 rotates at the bottom of the first fixed plate 304, the second rotating disk 309 will drive the displacement rod 305 to rotate synchronously while the second rotating disk 309 rotates. At the same time, it will also drive the leveling circular plate 310 fixed at the bottom of the displacement rod 305 to rotate synchronously. The downward pressure and rotation of the leveling circular plate 310 can ensure that the automobile diaphragm maintains proper contact with the heating source during the quenching process, thereby making the heat distribution more uniform, thereby avoiding local overheating or underheating and improving the quenching quality.

[0044] like Figure 5 and Figure 8 As shown, the interior of the workbench 1 described in this embodiment is provided with a lifting limit mechanism 4 for lifting the height, and the lifting limit mechanism 4 includes a fixed cylinder 401, and the fixed cylinder 401 is fixedly connected to the interior of the workbench 1, and a first sliding column 402 is slidably connected to the interior of the fixed cylinder 401, and the top of the first sliding column 402 is rotatably connected to a pulley 403, and a groove is provided in the limit plate 203, and an arc-shaped baffle 413 is fixedly connected to the side wall of the groove of the limit plate 203.

[0045] Specifically, when the leveling circular plate 310 is pressed down, it will contact the pulley 403 and push the first sliding column 402 to move downward along the guide of the fixed cylinder 401 through the pulley 403. However, since the leveling circular plate 310 needs to rotate during the working process, the setting of the pulley 403 can reduce the wear of the downward leveling mechanism 3 and the lifting limit mechanism 4 on the device during operation.

[0046] like Figure 5 As shown, in this embodiment, the bottom of the first sliding column 402 is fixedly connected to the first spring 404, and the bottom of the first spring 404 is fixedly connected to the bottom of the inner cavity of the fixed cylinder 401. The other end of the fixed cylinder 401 is internally slidably connected to the second sliding column 406, and the bottom of the second sliding column 406 is fixedly connected to the second spring 405, and the bottom of the second spring 405 is fixedly connected to the inner cavity of the fixed cylinder 401. The upper part of the second sliding column 406 is fixedly connected to the moving ring 410, and the upper part of the moving ring 410 is rotatably connected to the rotating ball 411 close to the inner ring surface.

[0047] Specifically, the leveling circular plate 310 will squeeze the first sliding column 402 to move downward along the guide of the fixed cylinder 401 during the downward pressing process, and will squeeze the fixed cylinder 401 at its bottom while moving. At the same time, since the fixed cylinder 401 is a "U"-shaped column and contains a liquid medium, the liquid medium inside the fixed cylinder 401 will be pushed to the other side when the first sliding column 402 moves downward, and will push the second sliding column 406 to move upward while flowing, and will synchronously drive the moving ring 410 and the rotating ball 411 to move synchronously. The setting of the rotating ball 411 can facilitate the leveling of the automobile diaphragm on the moving ring 410, and at the same time, pushing the automobile diaphragm away from the heating ring 205 can avoid direct contact with the heating ring 205, thereby avoiding wear or scratches on the surface of the heating ring 205 during the leveling process, thereby protecting the integrity of the heating ring 205.

[0048] like Figure 6 、 Figure 7 and Figure 8 As shown, in this embodiment, the top of the second sliding column 406 is fixedly connected to the second fixed plate 407, an inner cavity is opened inside the second fixed plate 407, the side wall of the inner cavity of the second fixed plate 407 is fixedly connected to the third spring 408, the other end of the third spring 408 is fixedly connected to the oblique movable plate 409, and the top of the limit plate 203 is rotatably connected to the buckle 412.

[0049] Specifically, when the second sliding column 406 moves upward, the two groups of buckles 412 rotating on the limit plate 203 are in an inward buckled state, and a certain length of the bottom of the buckle 412 extends out of the groove opened on the limit plate 203. Since the third spring 408 is not affected by the external force at this time and is in an unstressed state, when the second sliding column 406 moves upward with the second fixed plate 407, the third spring 408 and the oblique movable plate 409, the top of the oblique movable plate 409 will abut against the bottom of the buckle 412, and continue to push the buckle 412 to rotate around the central axis during the upward movement. When the side of the buckle 412 abuts against the arc baffle 413, the buckle 412 will stop rotating. , and the inclination of the bottom of the buckle 412 will fit with the inclined structure on the oblique movable plate 409, and will continue to push the oblique movable plate 409 to move away from the buckle 412 while the second sliding column 406 continues to move. At this time, the third spring 408 is in a compressed state. When the second sliding column 406 drives the second fixed plate 407, the third spring 408 and the oblique movable plate 409 to move above the buckle 412, the third spring 408 will be reset without being affected by external force, and at the same time drive the oblique movable plate 409 back to its initial state. The setting of the buckle 412 can avoid the deviation of the automobile diaphragm during rotation, further improving the heating effect of the automobile diaphragm separation finger.

[0050] Working principle: when the automobile diaphragm is heated, the cylinder 302 is started, and the cylinder 302 will push the telescopic column 303 to move downward, and simultaneously pull the first fixed plate 304 fixed on its top to move synchronously. When the first fixed plate 304 moves, the displacement rod 305 on the lower surface of the other side of the first fixed plate 304 will be driven to move synchronously. The downward pressure of the displacement rod 305 can provide corresponding power support for subsequent components.

[0051] Since the bottom of the displacement rod 305 and the upper part of the leveling circular plate 310 are fixed, the displacement rod 305 will drive the leveling circular plate 310 to move synchronously when it moves downward. When the bottom of the leveling circular plate 310 contacts the upper part of the automobile diaphragm, the leveling circular plate 310 will continue to press down, and at the same time, start the drive motor 306. Since the output shaft of the drive motor 306 and the first rotating disk 307 are fixed, the first rotating disk 307 will rotate synchronously when the drive motor 306 is started, and at the same time, it will drive the second belt 308 on its outer ring surface to transmit, which will synchronously drive the second rotating disk 309 rotates. Since the interior of the second rotating disk 309 is provided with a protrusion adapted to the groove on the outer annular surface of the displacement rod 305, and the displacement rod 305 rotates at the bottom of the first fixed plate 304, the second rotating disk 309 will drive the displacement rod 305 to rotate synchronously while the second rotating disk 309 rotates, and will also drive the leveling circular plate 310 fixed at the bottom of the displacement rod 305 to rotate synchronously. The downward pressure and rotation of the leveling circular plate 310 can ensure that the automobile diaphragm maintains proper contact with the heating source during the quenching process, thereby making the heat distribution more uniform, thereby avoiding local overheating or underheating and improving the quenching quality.

[0052] When the leveling circular plate 310 is pressed down, it will contact the pulley 403 and push the first sliding column 402 to move downward along the guide of the fixed cylinder 401 through the pulley 403. However, since the leveling circular plate 310 needs to rotate during the operation, the setting of the pulley 403 can reduce the wear of the device caused by the downward pressing leveling mechanism 3 and the lifting limit mechanism 4 during operation.

[0053] During the downward pressing process, the leveling circular plate 310 will squeeze the first sliding column 402 to move downward along the guide of the fixed cylinder 401, and will squeeze the fixed cylinder 401 at its bottom while moving. At the same time, since the fixed cylinder 401 is a "U"-shaped column and contains a liquid medium, when the first sliding column 402 moves downward, it will push the liquid medium inside the fixed cylinder 401 to flow to the other side, and while flowing, it will push the second sliding column 406 to move upward, and will synchronously drive the moving ring 410 and the rotating ball 411 to move synchronously. The setting of the rotating ball 411 can facilitate the leveling of the automobile diaphragm on the moving ring 410, and at the same time, pushing the automobile diaphragm away from the heating ring 205 can avoid direct contact with the heating ring 205, thereby avoiding wear or scratches on the surface of the heating ring 205 during the leveling process, thereby protecting the integrity of the heating ring 205.

[0054] When the second sliding post 406 moves upward, the two groups of buckles 412 rotating on the limit plate 203 are in an inward buckled state, and a certain length of the bottom of the buckle 412 extends out of the groove opened on the limit plate 203. Since the third spring 408 is not affected by the external force at this time and is in a non-stressed state, when the second sliding post 406 moves upward with the second fixed plate 407, the third spring 408 and the oblique movable plate 409, the top of the oblique movable plate 409 will abut against the bottom of the buckle 412, and continue to push the buckle 412 to rotate around the central axis during the upward movement. When the side of the buckle 412 abuts against the arc baffle 413, the buckle 412 will stop rotating, and The inclination of the bottom of the buckle 412 will fit with the inclined structure on the oblique movable plate 409, and will continue to push the oblique movable plate 409 to move away from the buckle 412 while the second sliding column 406 continues to move. At this time, the third spring 408 is in a compressed state. When the second sliding column 406 drives the second fixed plate 407, the third spring 408 and the oblique movable plate 409 to move above the buckle 412, the third spring 408 will be reset without being affected by external force, and at the same time drive the oblique movable plate 409 back to its initial state. The setting of the buckle 412 can avoid the deviation of the automobile diaphragm during rotation, further improving the heating effect of the automobile diaphragm separation finger.
