Description

Technical Field

[0001] This utility model relates to a shock absorber processing device, specifically a burr removal device for shock absorber processing, belonging to the technical field of shock absorber processing devices. Background Technology

[0002] Shock absorbers are used to suppress the oscillations caused by the rebound of the spring after absorbing shock and the impact from the road surface. They are widely used in automobiles, motorcycles and other fields to accelerate the attenuation of vibrations in the frame and body, thereby improving the ride smoothness of the vehicle. When driving over uneven roads, although the shock-absorbing spring can filter the vibrations of the road surface, the spring itself will still have reciprocating motion. The shock absorber is used to suppress this spring jumping. During the manufacturing process, the surface of the shock absorber has a lot of burrs, which requires the use of a burr removal device for processing.

[0003] However, most existing deburring devices have various problems. For example, in the deburring device for processing shock absorber brackets disclosed in publication number CN219704440U, although the grinding rod can be adapted to remove burrs on the inside and outside of the pipes on the shock absorber bracket, and the angle of the grinding rod can be changed to make it suitable for removing burrs on the inside and outside of pipes of different diameters, in addition to the method of using a grinding rod for deburring, there is also the method of using a vibratory grinder for deburring. When using a vibratory grinder, the shock absorber to be processed is usually placed in a vibratory sandbox. The high-speed vibration drives the abrasive gravel to vibrate and rub against the shock absorber to achieve the deburring effect. However, when the abrasive gravel vibrates at high speed, the shock absorber located at the top of the sandbox will slowly move down to the bottom of the sandbox, causing the shock absorber to contact the bottom of the box. At this time, it is necessary to manually remove the shock absorber from the box and put it back on top of the sandbox. The operation is cumbersome and time-consuming. Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing technologies are too simplistic. Specifically, the purpose of this utility model is to solve the aforementioned shortcomings in existing technologies by proposing a burr removal device for shock absorber processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A burr removal device for processing shock absorbers includes a vibratory grinding sand box, a support frame, a shock absorber, a clamping mechanism, and a linkage mechanism. Two support frames are provided and symmetrically fixed on both sides of the vibratory grinding sand box. The shock absorber is placed inside the vibratory grinding sand box.

[0007] The clamping mechanism is mounted on the support frame and includes a guide rod, a contact plate, a rack, a linkage rod, and a helical gear. The guide rod is slidably connected to the vibratory grinding sand box and the support frame. The contact plate is fixed to one end of the guide rod and is located inside the vibratory grinding sand box, abutting against the shock absorber. The rack is fixed to the end of the guide rod away from the contact plate. The linkage rod is slidably connected to one side of the support frame and rotatably connected to the support frame. The helical gear is coaxially fixed to the linkage rod and meshes with the rack.

[0008] The linkage mechanism is located on one side of the support frame.

[0009] As a further improvement of this utility model: two helical gears are coaxially fixed on the linkage rod, and the two helical gears are arranged in a one-to-one correspondence with the rack.

[0010] As a further embodiment of this utility model: the linkage mechanism includes a transmission sleeve, a locking block, and a transmission gear. The transmission sleeve is sleeved on the linkage rod, the locking block is fixed on the side wall of the linkage rod, and a groove is provided on the inner wall of the transmission sleeve. The locking block is slidably engaged in the groove of the transmission sleeve, and the transmission gear is coaxially fixed at the center of the outer side of the transmission sleeve.

[0011] As a further embodiment of this utility model: the linkage mechanism further includes an adjusting rack, a lead screw, and a driven gear. A through hole is provided through the support frame, the lead screw is slidably connected in the through hole, the adjusting rack is fixed to one end of the lead screw and meshes with one side of the transmission gear, the driven gear is rotatably connected to the support frame, and a threaded hole is provided through the center of the driven gear, and the lead screw is threaded into the threaded hole of the driven gear.

[0012] As a further embodiment of this utility model: the linkage mechanism further includes a drive gear and a servo motor. The servo motor is fixed on the support frame, the drive gear is coaxially fixed with the output shaft of the servo motor, and the drive gear meshes with the driven gear.

[0013] As a further improvement of this utility model: the diameter of the driven gear is larger than that of the driving gear, and both the driven gear and the driving gear are helical gear structures.

[0014] The beneficial effects of this utility model are:

[0015] In this invention, a clamping mechanism and a linkage mechanism are provided. The rotation of the helical gear in the clamping mechanism drives the rack to mesh and link, thereby causing the guide rod to slide and the abutment plate to abut against the shock absorber, thus fixing the shock absorber in the vibratory grinding sand box. At the same time, through the sliding connection structure between the linkage rod and the support frame, when the helical gear meshes with the rack, the linkage rod can drive the helical gear to slide, thereby allowing the two adjacent guide rods to slide to different degrees. This allows the clamping mechanism to adapt to the diameter of the shock absorber and clamp and lock it. Simultaneously, the linkage mechanism allows the lead screw to mesh and link with the driven gear, thereby driving the adjusting rack to link, and the adjusting rack drives the transmission gear to mesh and link.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0022] like Figures 1 to 4 As shown, a burr removal device for shock absorber processing includes a vibratory grinding sand box 1, a support frame 2, a shock absorber 3, a clamping mechanism 4, and a linkage mechanism 5. Two support frames 2 are provided and symmetrically fixed on both sides of the vibratory grinding sand box 1. The shock absorber 3 is placed inside the vibratory grinding sand box 1.

[0023] The clamping mechanism 4 is mounted on the support frame 2 and includes a guide rod 41, an abutment plate 42, a rack 43, a linkage rod 44, and a helical gear 45. The guide rod 41 is slidably connected to the vibratory grinding sand box 1 and the support frame 2. The abutment plate 42 is fixed to one end of the guide rod 41 and is located inside the vibratory grinding sand box 1, abutting against the shock absorber 3. The rack 43 is fixed to the end of the guide rod 41 away from the abutment plate 42. The linkage rod 44 is slidably connected to one side of the support frame 2 and is rotatably connected to the support frame 2. The helical gear 45 is coaxially fixed to the linkage rod 44 and meshes with the rack 43.

[0024] The linkage mechanism 5 is located on one side of the support frame 2. The linkage mechanism 5 includes a transmission sleeve 51, a locking block 52, and a transmission gear 53. The transmission sleeve 51 is sleeved on the linkage rod 44. The locking block 52 is fixed on the side wall of the linkage rod 44 and a slot is provided on the inner wall of the transmission sleeve 51. The locking block 52 is slidably engaged in the slot of the transmission sleeve 51. The transmission gear 53 is coaxially fixed at the center of the outside of the transmission sleeve 51.

[0025] The linkage mechanism 5 also includes an adjusting rack 54, a lead screw 55, and a driven gear 56. A through hole is provided through the support frame 2. The lead screw 55 is slidably connected in the through hole. The adjusting rack 54 is fixed to one end of the lead screw 55 and meshes with one side of the transmission gear 53. The driven gear 56 is rotatably connected to the support frame 2 and a threaded hole is provided through the center of the driven gear 56. The lead screw 55 is threaded into the threaded hole of the driven gear 56.

[0026] The linkage mechanism 5 also includes a drive gear 57 and a servo motor 58. The servo motor 58 is fixed on the support frame 2. The drive gear 57 is coaxially fixed with the output shaft of the servo motor 58, and the drive gear 57 meshes with the driven gear 56.

[0027] In this utility model, by setting up a clamping mechanism 4 and a linkage mechanism 5, the rotation of the helical gear 45 in the clamping mechanism 4 drives the rack 43 to mesh and link, thereby driving the guide rod 41 to slide, and causing the abutment plate 42 to abut against the shock absorber 3, thereby fixing the shock absorber 3 in the vibratory grinding sand box 1. At the same time, through the sliding connection structure between the linkage rod 44 and the support frame 2, when the helical gear 45 meshes and links with the rack 43, the linkage rod 44 can drive the helical gear 45 to slide, thereby allowing the two adjacent guide rods 41 to slide to different degrees. This allows the clamping mechanism 4 to adapt to the diameter of the shock absorber 3 and clamp and lock it. At the same time, the linkage mechanism 5 enables the lead screw 55 to mesh and link with the driven gear 56, thereby driving the adjusting rack 54 to link, and the adjusting rack 54 drives the transmission gear 53 to mesh and link. Example 2

[0028] like Figures 1 to 4 As shown, in addition to all the technical features included in Embodiment 1, this embodiment also includes:

[0029] Two helical gears 45 are coaxially fixed on the linkage rod 44, and the two helical gears 45 are arranged in a one-to-one correspondence with the rack 43. When the two helical gears 45 mesh with the rack 43, the linkage rod 44 can drive the helical gears 45 to slide, thereby allowing the two adjacent guide rods 41 to slide to different degrees, so that the clamping mechanism 4 can adapt to the diameter of the shock absorber 3 and clamp and lock it.

[0030] The driven gear 56 has a larger diameter than the driving gear 57, and both the driven gear 56 and the driving gear 57 are helical gears. The torque of the servo motor 58 is increased by gear sets of different diameters, and the stability of gear transmission is improved by the helical gear structure.

[0031] Working principle: When using this shock absorber processing device, first place the shock absorber 3 in the vibratory grinding sand box 1, then drive the active gear 57 to rotate through the servo motor 58, which in turn drives the driven gear 56 to mesh and link. At this time, the lead screw 55 is threaded in the screw hole of the driven gear 56 and drives the adjusting rack 54 to link. Through the adjusting rack 54, the transmission gear 53 is driven to mesh and link. At this time, the linkage rod 44 and the helical gear 45 rotate synchronously. Through the helical gear 45, the rack 43 is meshed and linked. At this time, the guide rod 41 slides until the abutment plate 42 abuts and locks against the shock absorber 3.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
