Description

Technical Field

[0001] This utility model relates to the field of spring pressing equipment technology, and in particular to a precision pressing equipment for motorcycle shock absorber springs with an automatic alignment structure. Background Technology

[0002] In the field of motorcycle shock absorber manufacturing, spring press-fitting equipment is the core device to ensure the assembly accuracy of the shock absorber assembly. Traditional press-fitting equipment usually uses a rigid hydraulic drive mechanism with a fixed clamp to press the spring and cylinder together. The operation process is as follows: the shock absorber cylinder is fixed to the positioning block, the spring is placed, and then the hydraulic system is started. The assembly is completed by pressing down in a straight line through the press head. Although such equipment can meet the basic assembly requirements, the movement trajectory of the traditional press head is a rigid vertical guide. However, due to manufacturing tolerances or design requirements, the end face of the motorcycle shock absorber spring often has an inclined angle. When the rigid press head contacts the inclined end face, a horizontal component force is generated, causing the contact point between the spring end face and the press head to shift, forming a local stress concentration and accelerating the wear of the coating on the spring surface. At the same time, the spring axis deflects during the press-fitting process, causing the spring and cylinder to be misaligned, resulting in abnormal noise during shock absorber operation. In extreme cases, the spring slips laterally off the press head, requiring the machine to be stopped and reset, which seriously reduces production efficiency.

[0003] Therefore, to address the aforementioned issues, a precision pressing device for motorcycle shock absorber springs with an automatic alignment structure is proposed. This device employs a combination of spherical hinge and elastic reset structure, enabling the pressure head to achieve tilt compensation and radial floating. It can sense the spring end face angle and automatically adjust the pressing axis, ensuring that the pressure always acts perpendicularly to the spring center, thus eliminating the off-center load problem caused by traditional rigid pressure heads. Utility Model Content

[0004] To overcome the problems encountered in the daily operation of traditional motorcycle shock absorber spring pressing equipment, where the movement trajectory of the traditional press head is rigidly vertically guided, while the end face of the motorcycle shock absorber spring often has an inclined angle due to manufacturing tolerances or design requirements, when the rigid press head contacts the inclined end face, a horizontal component force is generated, causing the contact point between the spring end face and the press head to shift, forming local stress concentration and accelerating the wear of the spring surface coating; at the same time, the spring axis deflects during the pressing process, causing the spring and cylinder to be misaligned, resulting in abnormal noise during shock absorber operation; and in extreme cases, the spring slips laterally off the press head, requiring the machine to be stopped and reset, which seriously reduces production efficiency.

[0005] The technical solution of this utility model is as follows: a precision pressing device for motorcycle shock absorber springs with an automatic alignment structure, comprising a top plate, a pressing assembly, a connecting assembly, a fixing assembly, a placement assembly, and a support assembly. The pressing assembly is located inside the top plate, the connecting assembly is located inside the top plate, the fixing assembly is located inside the connecting assembly, the placement assembly is located above the connecting assembly, and the support assembly is located below the connecting assembly. The pressing assembly includes a fixing frame, a hydraulic rod, a first connecting rod, a ball frame, a rotating shaft, an annular frame, a second connecting rod, a top block, a return spring, an annular pressure plate, and ball bearings. A fixing frame is provided on the inner side of the top plate, and a hydraulic rod is provided on the inner side of the fixing frame. A first connecting rod is provided at one end of the hydraulic rod, and a ball bearing is provided on the outer side of the first connecting rod. The first connecting rod and the hydraulic rod are rotatably connected through the ball bearing. A spherical frame is provided below the first connecting rod, and a rotating shaft is provided on the inner side of the spherical frame. An annular frame is provided on the outer side of the rotating shaft. The annular frame and the bearing are rotatably connected. A second connecting rod is provided below the spherical frame, and a top block is provided at the lower end of the second connecting rod. A return spring is provided below the annular frame. Multiple sets of return springs are provided, and an annular pressure plate is provided at one end of the return spring.

[0006] Preferably, the first connecting rod moves up and down through the extension and retraction of the hydraulic rod. This movement of the first connecting rod, in turn, causes the annular frame and the top block to move up and down. As the annular frame moves up and down, the annular pressure plate comes into contact with the top of the motorcycle shock absorber spring. Since one end of the shock absorber spring has a certain tilt angle, when the shock absorber spring and the annular pressure plate come into contact, the annular pressure plate is subjected to pressure, causing the return spring to extend and retract, and the annular frame to rotate around the pivot. The ball bearing allows the annular frame to rotate horizontally, allowing the annular pressure plate to float radially under pressure and compensate for the tilt angle of the shock absorber spring end face. This ensures that the pressure axis always coincides with the center line of the shock absorber spring, preventing the shock absorber spring from laterally slipping due to angular deviation when the end face of the shock absorber spring comes into contact. This allows for quick alignment of the pressing end of the pressing assembly and the shock absorber spring during the pressing process, eliminating the off-center load problem caused by traditional rigid pressure heads.

[0007] Preferably, the connecting assembly includes a bracket and a base plate, with a bracket provided on the inner side of the top plate, and multiple sets of brackets provided, with the base plate provided at the lower end of the bracket.

[0008] Preferably, the fixing component includes a motor and a threaded rod. The motor is located on one side of the base plate, and the output end of the motor is provided with a threaded rod, which has two opposite threads.

[0009] Preferably, the fixing component also includes a first movable block and a first V-shaped bracket, the first movable block is provided on the outside of the threaded rod, the first movable block and the threaded rod are threadedly connected, and the first V-shaped bracket is provided on the top of the first movable bracket.

[0010] Preferably, the fixing component also includes a second movable block and a second V-shaped bracket. The second movable block is provided on the outside of the threaded rod, and the second movable block and the threaded rod are threadedly connected. The second V-shaped bracket is provided above the second movable block, and the first V-shaped bracket has a slot structure that matches the second V-shaped bracket.

[0011] Preferably, the placement component includes a fixing rod and a limiting ring, with the fixing rod positioned above the base plate and the limiting ring positioned above the fixing rod.

[0012] Preferably, the support assembly includes a support and a base, with the support located below the base plate, and multiple sets of supports provided, with the base located below the support.

[0013] The beneficial effects of this utility model are: The hydraulic rod extends and retracts, causing the first connecting rod to move up and down. This movement, in turn, causes the ring frame and top block to move up and down. As the ring frame moves, the ring pressure plate contacts the top of the motorcycle shock absorber spring. Because one end of the shock absorber spring has a certain tilt angle, when the spring contacts the ring pressure plate, the pressure plate is subjected to pressure, causing the spring to extend and retract, and the ring frame to rotate around the axis. The ball bearing allows the ring frame to rotate horizontally, enabling the ring pressure plate to float radially under pressure and compensate for the tilt angle of the shock absorber spring end face. This ensures that the pressure axis always coincides with the center line of the shock absorber spring, preventing lateral slippage of the spring due to angular deviation when the spring end face contacts the shock absorber. This allows for quick alignment of the pressing end of the pressing assembly and the spring during pressing, eliminating the off-center load problem caused by traditional rigid pressure heads.

An annular pressure plate 110 is provided at one end of the return spring 109.

[0017] Please see Figure 3 and Figure 4In this embodiment, the connecting assembly includes a bracket 201 and a base plate 202. The bracket 201 is disposed on the inner side of the top plate 1, and multiple sets of brackets 201 are provided. The base plate 202 is disposed at the lower end of the bracket 201. The fixing assembly includes a motor 301 and a threaded rod 302. The motor 301 is disposed on one side of the base plate 202, and the threaded rod 302 is disposed at the output end of the motor 301. The threaded rod 302 has two opposite threads. The fixing assembly also includes a first moving block 303 and a first V-shaped bracket 304. The first moving block 303 is disposed on the outer side of the threaded rod 302, and the first moving block 303 and the threaded rod 302 are threadedly connected. The first V-shaped bracket 304 is disposed above the first moving bracket. The fixing assembly also includes a second moving block 305 and a second V-shaped bracket 304. The frame 306 has a second moving block 305 on the outside of the threaded rod 302. The second moving block 305 is threadedly connected to the threaded rod 302. A second V-shaped frame 306 is provided above the second moving block 305. The first V-shaped frame 304 has a slot structure that matches the second V-shaped frame 306. In use, the starting motor 301 drives the threaded rod 302 to rotate, which drives the first moving block 303 and the second moving block 305 to move in opposite directions. The linear movement of the first moving block 303 and the second moving block 305 clamps and fixes the motorcycle shock absorber cylinder workpiece, and fixes the motorcycle shock absorber cylinder in the central part of the device and aligns it with the press-fit structure. At the same time, the V-shaped clamping structure can accommodate motorcycle shock absorber cylinders of different sizes.

[0018] The placement assembly includes a fixing rod 401 and a limiting ring 402. The fixing rod 401 is located above the base plate 202, and the limiting ring 402 is located above the fixing rod 401. The support assembly includes a support 501 and a base 502. The support 501 is located below the base plate 202. Multiple sets of supports 501 are provided, and the base 502 is located below the supports 501. In use, the spring pressing device is supported by the supports 501 and the base 502.

[0019] During operation, the equipment is first placed stably on the workbench using the support 501 and base 502 of the support assembly, ensuring that the base plate 202 is level. The motorcycle shock absorber cylinder workpiece is placed between the first V-shaped bracket 304 and the second V-shaped bracket 306 of the fixing assembly. The motor 301 is started to drive the threaded rod 302 to rotate. The two reverse threads on the threaded rod 302 drive the first moving block 303 and the second moving block 305 to move relative to each other along the base plate 202. The first V-shaped bracket 304 and the second V-shaped bracket 306 clamp the outer wall of the cylinder through the V-shaped slot structure, achieving automatic centering and alignment, ensuring that the cylinder axis coincides with the axis of the pressing assembly. Subsequently, the spring to be pressed is inserted into the fixing rod 401 of the placement assembly. The lower end of the spring abuts against the limiting ring 402 to complete the pre-positioning. At this time, the upper end of the spring may have a tilt angle due to manufacturing tolerances. The hydraulic rod 102 is activated to drive the first connecting rod 103 downward. The first connecting rod 103 is connected to the hydraulic rod 102 via a ball bearing 111, allowing the pressure head to rotate horizontally. The annular pressure plate 110 first contacts the top of the spring. If the spring end face is tilted, the annular pressure plate 110 is compressed and the return spring 109 is compressed. At the same time, the annular frame 106 rotates around the pivot 105 inside the spherical frame 104 to generate tilt angle compensation, so that the surface of the annular pressure plate 110 adaptively fits the angle of the spring end face. At this time, the ball bearing 111 allows the annular frame 106 to make slight adjustments to the direction of rotation in the horizontal plane, eliminating the offset between the spring axis and the pressure head axis. The hydraulic rod 102 continues to apply pressure, and the top block 108 transmits the pressure vertically to the center of the spring through the second connecting rod 107, avoiding the generation of horizontal component force, until the spring is completely pressed into the shock absorber cylinder. During the process, the elastic force of the return spring 109 compensates for the pressure head posture in real time, ensuring that the pressure always acts vertically on the spring axis. Once the spring is in place, the hydraulic rod 102 stops operating and maintains pressure for several seconds to ensure a stable assembly. Subsequently, the hydraulic rod 102 retracts, causing the pressing assembly to rise, and the annular pressure plate 110 resets under the action of the return spring 109. The motor 301 is turned off, and the threaded rod 302 is rotated in the opposite direction to loosen the cylinder body of the first V-shaped bracket 304 and the second V-shaped bracket 306, allowing the press-fitted shock absorber assembly to be removed. If continuous operation is required, the above steps can be repeated.

[0020] Through the above steps, the hydraulic rod 102 extends and retracts, causing the first connecting rod 103 to move up and down. The up-and-down movement of the first connecting rod 103 then causes the ring frame 106 and the top block 108 to move up and down. When the ring frame 106 moves up and down, the annular pressure plate 110 contacts the top of the motorcycle shock absorber spring. Because one end of the shock absorber spring has a certain angle of inclination, when the shock absorber spring contacts the annular pressure plate 110, the return spring 109 extends and retracts when the annular pressure plate 110 is under pressure, causing the ring frame 106 to rotate around the pivot 1. The 05 rotation, and the ball bearing 111 allows the ring frame 106 to rotate horizontally, so that the ring pressure plate 110 can generate radial floating under pressure and compensate for the tilt angle of the shock absorber spring end face. This ensures that the pressure axis can always coincide with the center line of the shock absorber spring, preventing the shock absorber spring from lateral slippage due to angular deviation when the shock absorber spring end face is in contact. This enables quick alignment of the pressing end of the pressing assembly and the shock absorber spring when pressing the shock absorber spring, eliminating the off-center load problem caused by the traditional rigid pressure head.

[0021] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
