Description

Technical Field

[0001] The present application relates to the field of spring grinding machines, and in particular to a swing spring grinding machine which is convenient for fixing springs. Background Art

[0002] The widespread use of springs has led to an increasing demand for springs. Springs are widely used in the current field of mechanisms. In order to ensure the verticality of the helical compression spring, keep the end faces of the two support rings in contact with other parts, reduce deflection and ensure the characteristics of the main machine, both end faces of the spring are generally ground. This process is usually called spring grinding. Spring grinding machines are generally used to grind the end faces of the springs.

[0003] At present, a Chinese utility model patent with publication number CN210360712U discloses a multifunctional spring grinding machine, including a placement plate, a clamping cylinder, a clamping plate, a grinding wheel drive motor, a grinding wheel, a turntable drive motor and a servo motor. The spring is placed on the placement plate, the clamping cylinder drives the clamping plate to clamp the spring, the grinding wheel drive motor drives the grinding wheel to rotate, the grinding wheel abuts against the end face of the spring, the turntable drive motor drives the placement plate with the spring placed thereon to swing, the spring swings relative to the grinding wheel, the grinding wheel grinds the end face of the spring, the servo motor drives the grinding wheel drive motor to slide, and the grinding wheel remains in a state of abutting against the spring.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the placement plate and the clamping plate compress the spring, and as the grinding wheel is driven by the servo motor to continuously approach the spring, and as the direction of the spring restricted by the placement plate and the clamping plate is different from the direction of force applied by the grinding wheel, the spring is easily moved away from the grinding wheel during the grinding process, resulting in inadequate grinding of the spring end face and low quality of the spring. Utility Model Content

[0005] In order to grind the end surface of the spring in place and improve the quality of the spring, the present application provides a swing-type spring grinding machine that is convenient for fixing the spring.

[0006] The present application provides a swing spring grinding machine that is convenient for fixing springs, which adopts the following technical solution:

[0007] A swing-type spring grinding machine for fixing a spring comprises a frame, a swing arm, a fixing assembly for fixing the spring and a grinding assembly, wherein the swing arm is rotatably connected to the frame, the fixing assembly comprises a support plate, a plurality of first abutment strips and a clamping portion, the support plate is arranged on the swing arm, a plurality of first abutment strips are distributed along the direction of the rotation axis of the swing arm and are arranged on the support plate, the clamping portion is used to clamp the spring against the support plate, the grinding assembly comprises a grinding wheel and a grinding motor, the grinding motor is used to drive the grinding wheel to rotate, the grinding motor is slidably connected to the frame, and the grinding wheel is used to grind the end face of the spring.

[0008] By adopting the above technical solution, the staff places the spring on the support plate, and several coils on the spring respectively abut on several first abutting strips. Then the clamping part clamps the spring on the support plate, and the grinding motor drives the grinding wheel to rotate. The grinding wheel continuously approaches the spring to grind the end face of the spring. Under the abutment of the first abutting strips, the spring cannot slip relative to the support plate, which reduces the spring slipping during the grinding process of the grinding wheel and causes the spring to fail to be polished into place, thereby improving the quality of the spring.

[0009] Optionally, the support plate is also provided with a sliding assembly for changing the distance between the plurality of first abutment strips, the sliding assembly comprising a plurality of sliding blocks, a plurality of matching blocks, a plurality of first connecting rods, a plurality of second connecting rods and a driving member, the sliding block farthest from the grinding wheel among the plurality of sliding blocks is arranged on the support plate, and the remaining sliding blocks are slidingly connected to the support plate in a direction approaching or away from the grinding wheel, the plurality of sliding blocks correspond one to one to the plurality of first abutment strips, the first abutment strip is arranged on the sliding block, the matching block, the first connecting rod and the second connecting rod form a group of adjusting parts, and the adjusting parts are respectively located between every two adjacent sliding blocks, one end of the first connecting rod is rotatably connected to the sliding block, one end of the second connecting rod is rotatably connected to the adjacent sliding block, the other end of the first connecting rod and one end of the second connecting rod are rotatably connected to the matching block, and the driving member is used to drive the plurality of matching blocks to move along a sliding direction perpendicular to the sliding direction of the sliding block.

[0010] By adopting the above technical solution, due to the different pitches of the springs, the pitches of different springs can be coped with by changing the distance between the first abutment strips. When the pitch of the spring becomes larger, the driving member drives the matching block to move, and the matching block makes the angle between the first connecting rod and the second connecting rod connected to the matching block larger, the spacing between the two adjacent sliding blocks becomes larger, and the distance between the adjacent first abutment strips becomes larger, which adapts to the pitches of different springs and improves the applicability of the first abutment strip.

[0011] Optionally, the driving member includes a driving rod and a screw rod, the length direction of the driving rod is parallel to the sliding direction of the sliding block, the driving rod is slidably connected to the support plate in a direction approaching or away from the sliding block, a plurality of matching blocks are slidably connected to the driving rod along the length direction of the driving rod, the length direction of the screw rod is parallel to the sliding direction of the driving rod, and the screw rod is rotatably connected to the support plate.

[0012] By adopting the above technical solution, when the pitch of the spring becomes larger, the staff rotates the screw to move the driving rod closer to the sliding block, and the matching block approaches the sliding block under the action of the driving rod. When the matching block approaches the sliding block, the angle between the first connecting rod and the second connecting rod rotatably connected to the same matching block becomes larger, so that the spacing between the matching blocks gradually increases, and the driving member drives several matching blocks to move together, thereby improving the speed of adjusting the spacing of the first abutment strips, and the screw makes it easier for the staff to operate the driving member.

[0013] Optionally, the sliding assembly also includes a rotating member for driving the first abutment bar to rotate, the rotating member includes a plurality of gears and a plurality of racks, the plurality of gears correspond one-to-one to a plurality of sliding blocks, the gears are rotatably connected to the sliding block, the first abutment bar is arranged on the gear, the plurality of gears correspond one-to-one to the plurality of racks, the length of the rack is parallel to the sliding direction of the driving rod, the rack is slidably connected to the sliding block, the rack is meshed with the gear, and the rack is slidably connected to the driving rod along the length direction of the driving rod.

[0014] By adopting the above technical solution, as the pitch of the spring becomes larger, the inclination angle of each turn of the spring will also become larger. When the staff rotates the screw, the screw drives the drive rod to move, the drive rod approaches the sliding block, the drive rod drives the rack to move, the rack slides relative to the sliding block, the rack drives the gear to rotate, and the gear drives the first abutment bar to rotate. During the movement of the drive rod, the spacing between the sliding blocks gradually increases. Since the rack slides on the drive rod, the rack also increases as the spacing between the sliding blocks increases, and the spacing between the racks also gradually increases.

[0015] Optionally, the support plate is also provided with a plurality of second abutment bars, and the plurality of second abutment bars are distributed along the direction of the rotation axis of the swing arm, and the support plate is provided with a plurality of linkage members for driving the plurality of second abutment bars to adjust their positions, the linkage members corresponding one-to-one to the plurality of second abutment bars, the linkage members comprising a mounting block, a linkage rod and a linkage block, the mounting block being slidably connected to the support plate in a direction approaching or moving away from the grinding wheel, the second abutment bar being rotatably connected to the mounting block, the second abutment bar corresponding one-to-one to the first abutment bar, one end of the linkage rod being rotatably connected to the first abutment bar, and the other end of the linkage rod being rotatably connected to the second abutment bar, the linkage rod being slidably connected to the linkage block, and the linkage block being slidably connected to the support plate in a direction approaching or moving away from the grinding wheel.

[0016] By adopting the above technical scheme, there are several second abutment bars on the support plate, and the support plate can place two springs at one time, which is convenient for end surface grinding of the two springs at the same time. The first abutment bar and the second abutment bar are linked by a linkage piece, and the linkage block limits the rotation of the linkage rod. When the first abutment bar rotates and displaces, the linkage rod and the linkage block move with the first abutment bar, and the second abutment bar rotates and displaces under the drive of the linkage rod and the linkage block. The linkage piece makes it possible to drive several first abutment bars and second abutment bars to move together through only one driving piece, so that the staff can adjust the first abutment bar to achieve the corresponding adjustment of the second abutment bar, which improves the adjustment speed of the staff and makes the distance angle between the several first abutment bars consistent with the distance angle between the several second abutment bars.

[0017] Optionally, the clamping part includes a clamping plate, a clamping gear, a clamping rack, a connecting rod and a clamping motor, the clamping rack is arranged on the swing rod, the length direction of the clamping rack is parallel to the length direction of the swing rod, the connecting rod is slidably connected to the clamping rack along the length direction of the clamping rack, the clamping gear is rotatably connected to the connecting rod, the clamping gear is meshed with the clamping rack, the clamping motor is used to drive the clamping gear to rotate, the clamping plate is arranged on the connecting rod, and the clamping plate is used to abut against a spring.

[0018] By adopting the above technical solution, when the spring is placed on the support plate and abuts against the first abutment strip, the staff then drives the clamping motor, the clamping motor drives the clamping gear to rotate, the clamping gear engages with the clamping rack, the clamping rack is on the swing rod, the clamping gear moves relative to the clamping rack, the clamping rack drives the connecting rod to slide, and the connecting rod drives the clamping plate to clamp the spring onto the support plate.

[0019] Optionally, the cross-section of the clamping plate along the direction approaching or away from the grinding wheel is arc-shaped, and an adaption part that adapts to springs of different diameters is provided on the clamping plate. The adaption part includes a plurality of clamping strips and a driving member for driving a plurality of the clamping strips to clamp springs and a plurality of transmission members. The length direction of the clamping strip is parallel to the sliding direction of the grinding wheel, and the clamping strip is slidably connected to the clamping plate along the radial direction of the arc-shaped cross-section of the clamping plate. The plurality of transmission members are used to move the plurality of the clamping plates.

[0020] By adopting the above technical solution, the spring is generally cylindrical, the abutment plate is arc-shaped, and several compression strips abut on the spring along the radial direction of the abutment plate. The compression strip can better fit the spring. Several compression strips abut the spring together, and the compression force on the spring is dispersed, which reduces the degree of compression on the spring surface and the degree of deformation of the spring surface due to the compression force. The compression of the spring by multiple compression strips also reduces the movement of the spring.

[0021] Optionally, a plurality of the transmission members are respectively located between every two adjacent compression strips, and the transmission members include a sleeve and a sliding rod, one end of the sleeve is arranged on the side wall of the compression strip, one end of the sliding rod is arranged on the side wall of the adjacent compression strip, and the sliding rod is slidably connected in the sleeve.

[0022] By adopting the above technical scheme, the clamping strips are distributed along the axis of the abutment plate, and the clamping strips slide radially along the abutment strips. There is an acute angle between adjacent clamping strips, and the sleeve and the slide rod move relative to each other. When the clamping strips are away from the axis, the sleeve and the slide rod move away from each other, and adjacent clamping strips are away from the axis of the abutment plate under the action of the sleeve and the slide rod. Several clamping strips can move the same distance through the sleeve and the slide rod. Only one clamping strip needs to be moved to achieve the same distance movement of all clamping strips. Several clamping strips are adjusted together, and the speed of adjusting the position of the clamping strips is improved, thereby better improving the speed of grinding the end face of the spring.

[0023] Optionally, the driving member includes a driving strip, which is slidably connected to the connecting rod, and a plurality of slots are provided on the driving strip, and the plurality of slots are used to engage with the gears, and one end of the driving strip is arranged on a plurality of clamping strips having the same sliding direction as the driving strip.

[0024] By adopting the above technical scheme, when the spring is placed on the supporting plate, the clamping motor drives the clamping gear to rotate, and the clamping gear meshes with the clamping rack to make the connecting rod move. During the movement of the connecting rod, the gear meshes with the slot of the driving bar, driving the driving bar to slide on the connecting rod. The connecting rod and the driving bar have the same direction of movement. In the process of the connecting rod approaching the spring, the driving bar moves relative to the connecting rod, and the driving bar drives one of the clamping bars to move. Under the action of the sleeve and the sliding rod, all the other clamping bars abut against the spring. The abutment plate can be driven close to the spring by the clamping motor alone, and the clamping bar clamps the spring. The operation is simple for the staff, so that the spring is fixed and stable, and can better adapt to springs of different diameters.

[0025] Optionally, one end of the clamping strip used to abut against the spring is provided with anti-slip grooves.

[0026] By adopting the above technical solution, the compression strip compresses the spring, and the anti-slip pattern compresses the spring better, thereby increasing the friction between the compression strip and the spring and reducing the slippage between the spring and the compression strip when the end face is ground.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. The first abutment strip supports the spring, reducing the displacement of the spring from the support plate due to the movement of the grinding wheel during the grinding process;

[0029] 2. The sliding assembly is used to change the distance between the first abutment strips and the angle of the first abutment strips, so as to better adapt to springs of different sizes and better match the inclination angle of the spring coil;

[0030] 3. The linkage member is used to change the first abutment strip and the second abutment strip on the support plate together, thereby improving the adjustment speed.

[0031] 4. The clamping part presses the spring between the clamping strip and the support plate, reducing the movement of the spring during grinding. BRIEF DESCRIPTION OF THE DRAWINGS
