Description

Technical Field

[0001] This utility model relates to the field of automotive suspension spring production technology, specifically a grinding device for automotive suspension spring production. Background Technology

[0002] Automotive suspension springs are one of the core components of the suspension system. Their main function is to support the weight of the vehicle body, buffer road impacts, and maintain wheel contact with the ground, thereby ensuring driving comfort and handling stability. During the manufacturing process of springs, both ends are usually ground to make the end surfaces flat, ensuring that the spring can stably bear force after installation and avoiding stress concentration or installation deviations caused by uneven end surfaces.

[0003] Currently, in the spring grinding process, clamping devices are typically used to fix the springs in place to prevent displacement or rotation during grinding. Traditional clamping devices mostly use mechanical clamping structures (such as manual screws, pneumatic clamps, etc.), which lack precise clamping force adjustment functions. If the operator does not stop the clamping action in time, the clamping force may be too large, causing the spring to undergo plastic deformation, affecting its mechanical properties and service life. Utility Model Content

[0004] The purpose of this invention is to provide a grinding device for the production of automotive suspension springs, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grinding device for automobile suspension spring production, comprising a base, a placement seat fixed to the top of the base, a support column fixed to the top of the base, a top plate fixed to the top of the support column, and a fixing component and a protective component arranged above the base.

[0006] The protective components include:

[0007] The abutment rod is used to drive the slider to move synchronously.

[0008] The oscillating block is used to synchronously drive the movement of the locking block.

[0009] The card block is used to limit the movement of the card slot.

[0010] Preferably, the fixing assembly includes a motor three, which is fixed to the top of the top plate. The output shaft of the motor three passes through the top plate. A screw two is rotatably connected to the surface of the top plate and the base. A groove is formed on the top of the screw two. The output shaft of the motor three extends into the groove. A fixing plate is fixed to the output shaft of the motor three. A sliding plate two is slidably connected to the output shaft of the motor three. A spring one is fixed to the side of the fixing plate near the sliding plate two. The end of the spring one away from the fixing plate is fixed to the outer surface of the sliding plate two. A fixing block is fixed to the end of the sliding plate two away from the spring one. A linkage groove is formed on the inner wall of the groove. The fixing assembly also includes a movable part. When the motor three rotates forward or backward, the fixing plate, the sliding plate, and the fixing block can rotate synchronously. The screw two can be rotated through the linkage groove.

[0011] Preferably, the movable component includes a drive plate disposed below the top plate. A stabilizing rod is fixed to the inner side of the top plate and the base. The stabilizing rod passes through the drive plate and is slidably connected to the drive plate. A screw rod passes through the drive plate and is threadedly connected to the drive plate. A clamping plate passes through and is slidably connected to the stabilizing rod. A spring is fixed to the top of the clamping plate. The top of the spring is fixed to the bottom of the drive plate. When the drive plate moves downward, the clamping plate clamps the spring through the spring.

[0012] Preferably, the abutment rod is fixed to the bottom of the driving plate, the top of the clamping plate has a sliding groove, the inner wall of the sliding groove is slidably connected to a slider, the end of the slider away from the stabilizing rod is fixed to a spring three, the end of the spring three away from the slider is fixed to the inner wall of the sliding groove, the inner side of the end of the slider away from the spring three is hinged to a swing block, the lower surface of the swing block is fixed to a spring four, the end of the spring four away from the swing block is fixed to the inner side of the slider, the end of the swing block away from the spring four has a movable groove, the inner wall of the movable groove is slidably connected to a locking block, the... A spring is fixed to the end of the locking block away from the stabilizing rod. The end of the spring is fixed to the inner wall of the movable groove. A slot is opened on the outer surface of the stabilizing rod. The surface of the clamping plate is in contact with the spring. The motor continues to work, and the clamping plate moves closer. The contact rod abuts against the inclined surface of the slider, pushing the slider to move the swing block and the locking block towards the stabilizing rod. The locking block enters the slot, and the stabilizing rod and the locking block limit each other. At this time, the clamping plate cannot continue to move down to apply pressure to the spring. The motor reverses, and the locking block drives the swing block to rotate counterclockwise. This will not affect the normal reset of the driving plate, and the locking block can be released.

[0013] Preferably, a motor is fixed to the right side of the base, the output shaft of the motor passes through the base, a screw is rotatably connected to the inner wall of the base, the output shaft of the motor is fixed to the right end of the screw, a threaded post is threaded through and threaded to the screw, the top of the threaded post passes through the base and is slidably connected to the base, a slide plate is fixed to the top of the threaded post, a motor is mounted on the top of the slide plate, and a grinding plate is fixed to the output shaft of the motor. When the motor is turned on, the screw drives the threaded post, the slide plate, and the motor to move closer to the placement seat, and at the same time, the motor is turned on to rotate the grinding plate to grind both ends of the spring.

[0014] Preferably, the top of the slider is set as an inclined surface, which allows the slider to move when it is abutted.

[0015] Preferably, the screw has two opposite threads, which can cause the threaded columns to move closer or further apart synchronously when rotated.

[0016] Compared with the prior art, this utility model provides a grinding device for the production of automotive suspension springs, which has the following beneficial effects:

[0017] 1. This grinding device for automotive suspension spring production, through the setting of protective components, ensures that when the clamping plate surface is in contact with the spring, the motor continues to work, the clamping plate moves closer and is driven to move, and the contact rod contacts the inclined surface of the slider. At this time, the slider drives the swing block and the locking block to move towards the stabilizer bar, so that the locking block enters the locking groove, and the top of the swing block contacts the inner wall of the slider. The stabilizer bar and the locking block limit each other, and at this time the clamping plate cannot continue to move down to apply pressure to the spring, avoiding the deformation of the spring due to excessive clamping force, which would affect the normal use thereafter.

[0018] 2. This grinding device for automotive suspension spring production, through its fixed components, allows for the following operation: when grinding is required, the motor is turned on in the forward direction, causing the fixed plate, slide plate 2, and fixed block to rotate. The surface of the fixed block contacts the inner wall of the connecting groove, and the screw 2 rotates, causing the driving plate to move the clamping plate downwards via the spring 2, which, in conjunction with the placement seat, clamps the spring. Turning the motor on in the reverse direction releases the spring. When the screw 2 cannot rotate, the fixed block slips between the connecting groove and the motor, without affecting the normal operation of the motor and preventing damage to the motor.

[0029] like Figures 1-9 As shown, this utility model provides a technical solution: a grinding device for automobile suspension spring production, including a base 1, a placement seat 4 fixed on the top of the base 1, a support column 2 fixed on the top of the base 1, a top plate 3 fixed on the top of the support column 2, and a fixing component 8 and a protective component 9 arranged above the base 1; the protective component 9 includes: an abutment rod 90, a sliding groove 91, a slider 92, a third spring 93, a swing block 94, a fourth spring 95, a movable groove 96, a locking block 97, a fifth spring 98, and a locking groove 99.

[0030] The fixing assembly 8 includes a motor 3 80, which is fixed to the top of the top plate 3. The output shaft of the motor 3 80 passes through the top plate 3. A screw 2 81 is rotatably connected between the top plate 3 and the surface of the base 1. A groove 82 is provided on the top of the screw 2 81. The output shaft of the motor 3 80 extends into the groove 82. A fixing plate 83 passes through and is fixed to the output shaft of the motor 3 80. A sliding plate 2 84 passes through and is slidably connected to the output shaft of the motor 3 80. A spring 1 85 is fixed to the side of the fixing plate 83 near the sliding plate 2 84. The end of the spring 1 85 away from the fixing plate 83 is fixed to the outer surface of the sliding plate 2 84. A fixing block 86 is fixed to the end of the sliding plate 2 84 away from the spring 1 85. The inner wall of the groove 82 has a... The linkage groove 87 and the fixed assembly 8 also include a movable part 88, which includes a drive plate 880. The drive plate 880 is located below the top plate 3. A stabilizing rod 883 is fixed to the inner side of the top plate 3 and the base 1. The stabilizing rod 883 passes through the drive plate 880 and is slidably connected to the drive plate 880. A screw 81 passes through the drive plate 880 and is threadedly connected to the drive plate 880. A clamping plate 882 passes through and is slidably connected to the stabilizing rod 883. A spring 881 is fixed to the top of the clamping plate 882. The top of the spring 881 is fixed to the bottom of the drive plate 880. When the motor 80 is turned on and rotates forward, the fixed plate 83, the sliding plate 84, and the fixed block 86 rotate. The surface of the fixed block 86 abuts against the inner wall of the linkage groove 87. The screw 81 rotates, causing the driving plate 880 to move the clamping plate 882 down through the spring 881. The spring is clamped by the placement seat 4. The motor 80 can be turned on to release the spring. When the screw 81 cannot rotate, the fixed block 86 slips between the linkage groove 87, which will not affect the normal operation of the motor 80.

[0031] The abutment rod 90 is fixed to the bottom of the drive plate 880. A groove 91 is provided on the top of the clamping plate 882. A slider 92 is slidably connected to the inner wall of the groove 91. A spring 93 is fixed to the end of the slider 92 away from the stabilizer rod 883. The end of the spring 93 away from the slider 92 is fixed to the inner wall of the groove 91. A swing block 94 is hinged to the inner side of the end of the slider 92 away from the spring 93. A spring 95 is fixed to the lower surface of the swing block 94. The end of the spring 95 away from the swing block 94 is fixed to the inner side of the slider 92. The end of the swing block 94 away from the spring 95 is open... A movable groove 96 is provided, and a locking block 97 is slidably connected to the inner wall of the movable groove 96. A spring 98 is fixed to the end of the locking block 97 away from the stabilizer rod 883. The end of the spring 98 away from the locking block 97 is fixed to the inner wall of the movable groove 96. A slot 99 is opened on the outer surface of the stabilizer rod 883. The top of the slider 92 is set as an inclined surface. The surface of the clamping plate 882 is in contact with the spring. The motor 80 continues to work, and the clamping plate 882 moves closer and drives it to move. The abutting rod 90 abuts against the inclined surface of the slider 92, pushing the slider 92 to move the swing block 94 and the locking block 97 toward the stabilizer rod 883. The locking block 97 enters the slot 99, and the top of the swing block 94 abuts against the inner wall of the slider 92, so that the stabilizer rod 883 and the locking block 97 are mutually limited. At this time, the clamping plate 882 cannot continue to move down to apply pressure to the spring, so as to avoid deformation of the spring due to excessive clamping force.

[0032] A motor 5 is fixed to the right side of the base 1. The output shaft of the motor 5 passes through the base 1. A screw 6 is rotatably connected to the inner wall of the base 1. The output shaft of the motor 5 is fixed to the right end of the screw 6. A threaded post 7 is threaded through and threaded to the screw 6. The top of the threaded post 7 passes through the base 1 and is slidably connected to the base 1. A slide plate 10 is fixed to the top of the threaded post 7. A motor 11 is installed on the top of the slide plate 10. A grinding plate is fixed to the output shaft of the motor 11. The screw 6 has two opposite threads. When the motor 5 is turned on, the screw 6 drives the threaded post 7, the slide plate 10, and the motor 11 to move closer to the placement seat 4. At the same time, the motor 11 is turned on to make the grinding plate rotate and grind the two ends of the spring.

[0033] When grinding the car suspension springs, place the springs on top of the mounting base 4. Then, turn on motor 3 (80) to rotate forward, causing the fixing plate 83, sliding plate 2 (84), and fixing block 86 to rotate. The surface of fixing block 86 contacts the inner wall of the connecting groove 87, synchronously driving screw 2 (81) to rotate. This causes the driving plate 880 to move the clamping plate 882 downwards via spring 2 (881), clamping the springs in conjunction with the mounting base 4. Anti-slip rubber pads are fixed to the side of clamping plate 882 closest to the mounting base 4 to prevent rotation during grinding. When motor 2 (11) continues to operate, clamping plate 882 moves closer, spring 2 (881) compresses, and the contact rod 90 contacts the inclined surface of slider 92, pushing slider 92 to move the swing block 94 and locking block 97 towards the stabilizing rod 883. When the surface of the locking block 97 contacts the surface of the stabilizing rod 883, the locking block 97 moves into the movable groove 96, and the spring 98 is compressed. When the position of the locking block 97 is parallel to the movable groove 96, the spring 98 is released, and the locking block 97 enters the locking groove 99. At the same time, the top of the swing block 94 contacts the inner wall of the slider 92, so that the stabilizing rod 883 and the locking block 97 are mutually limited. At this time, the clamping plate 882 cannot continue to move down to apply pressure to the spring, so as to avoid the spring deformation due to excessive clamping force. After the clamping plate 882 is limited, the driving plate 880 cannot move, the screw 81 cannot rotate, and the fixed block 86 slips between the connecting groove 87. The spring 85 causes the sliding plate 84 to move back and forth, protecting the motor 80 to work normally. At this time, the motor 5 is turned on, and the screw 6 drives the threaded column 7, the sliding plate 10, and the motor 11 to move closer to the placement seat 4. At the same time, the motor 11 is turned on to rotate the grinding plate and grind the two ends of the spring. After grinding, turn on the motor to reverse 80. The surface of the locking block 97 contacts the inner wall of the slot 99, causing the swing block 94 to rotate counterclockwise. This releases the limit and resets the clamping plate 882 and the driving plate 880, allowing the spring to be released for easy removal.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
