Description

Technical Field

[0001] This utility model relates to the field of shock absorber processing technology, and in particular to a shock absorber front fork riser processing device. Background Technology

[0002] The fork seat tube (also known as the fork connector tube) is part of the fork tube assembly. Its lower end connects to the fork connector, and its upper part connects to the steering wheel (or handlebars). The structure of this fork tube assembly is as follows: Figure 1 As shown, in the processing of the fork riser, the cut round tube undergoes three processes: tube reduction, punching, and chamfering. After chamfering, the fork riser needs to be turned to obtain a fork riser that matches the fork connector. Currently, existing fork riser technology still uses traditional distributed hydraulic equipment, and manual handling is required to transport the tube to the corresponding equipment for manual processing, which is extremely inefficient.

[0038] like Figures 4 to 12 As shown, this embodiment provides a shock absorber fork riser processing device, which processes the fork riser 100 and forms a reduced section 101, a connecting hole 102, and a chamfer at the front end of the fork riser 100 to facilitate subsequent assembly of the fork riser 100. Furthermore, after chamfering, the fork riser 100 needs to be turned to ensure that the front end of the fork riser 100 is matched and connected to the fork connector.

[0039] Here, the shock absorber fork riser processing device includes a lifting hopper 2, a feeder 3, a pipe shrinking and conveying mechanism 4, a pipe shrinking machine 5, a pipe punching and chamfering mechanism 6, a conveying and unloading mechanism 7, and an unloading conveyor belt 8. The lifting hopper 2 stores the fork risers 100 to be processed. The lifting hopper 2 lifts and loads the fork risers 100 to be processed one by one onto the feeder 3; the feeder 3 then transports the fork risers 100 to be processed. When the fork risers 100 are transported to the pipe shrinking and conveying mechanism 4, the pipe shrinking and conveying mechanism 4 clamps the fork risers 100 on the feeder 3, and the pipe shrinking machine 5 shrinks the ends of the fork risers 100 to achieve pipe shrinking processing. It should be noted that the pipe shrinking machine 5 in this embodiment is existing mature equipment and will not be described in detail here. After the fork riser 100 undergoes tube reduction processing, it is returned to the feeder 3 for continued forward transport to the pipe punching and chamfering mechanism 6. The pipe punching and chamfering mechanism 6 punches and chamfers the fork riser 100, which is then transported by the conveying and unloading mechanism 7. The unmachined fork riser 100 is then transported to the lathe assembly 9 for machining, and the machined fork riser 100 is transported to the unloading conveyor belt 8 for unloading. The lathe assembly 9 is a conventional device, and its specific structure will not be described in detail here.

[0040] Here, the pipe punching and chamfering mechanism 6 includes a first lower support frame 61, a worktable 62 mounted on the first lower support frame 61, a punching and chamfering feeding support 63 mounted on the worktable 62 and placed inside the feeder 3, a punching and chamfering execution mechanism 64 mounted on the worktable 62, and a pushing feeding mechanism and a pushing unloading mechanism fixed on the worktable 62. The feeder 3 places the fork upright 100 on the punching and chamfering feeding support 63, and the pushing feeding mechanism pushes the fork upright 100 on the punching and chamfering feeding support 63 into the punching and chamfering execution mechanism 64, where punching and chamfering operations are performed. After processing, the pushing unloading mechanism pushes the fork upright 100 from the punching and chamfering execution mechanism 64 back to the punching and chamfering feeding support 63.

[0041] In this embodiment, the punching and chamfering actuator 64 performs two processes on the front fork riser 100: punching and chamfering. It includes a first housing side plate 6401 and a second housing side plate 6402 fixed on the worktable 62; a housing top plate disposed on the first housing side plate 6401 and the second housing side plate 6402; a pressing and clamping cylinder 6403 fixed on the first housing side plate 6401; an end linkage plate 6404 connected to the pressing and clamping cylinder 6403; several sliding guide rods 6407 disposed between the first housing side plate 6401 and the second housing side plate 6402; and a transmission rod whose one end is connected to the end linkage plate 6404, whose other end passes through the first housing side plate 6401, and which is arranged parallel to the sliding guide rods 6407. 6405, a left-right movable clamping linkage plate 6406 fixed on the transmission rod 6405 and positioned between the first housing side plate 6401 and the second housing side plate 6402, a second extrusion clamping module disposed between the left-right movable clamping linkage plate 6406 and the second housing side plate 6402, a first extrusion clamping module disposed between the left-right movable clamping linkage plate 6406 and the first housing side plate 6401, a chamfering and milling module disposed on the second housing side plate 6402 and the housing top plate, and a hydraulic punching machine 6416 disposed opposite to the first housing side plate 6401 and corresponding to the position of the first extrusion clamping module. The hydraulic punching machine 6416 punches holes in the front fork stem 100 to obtain connecting holes 102. Additionally, the chamfering and milling module chamfers the front end of the front fork stem 100. In this implementation, the left and right moving clamping linkage plate 6406 is slidably sleeved on the sliding guide rod 6407 and clamps the front fork riser tube 100.

[0042] In this embodiment, the first extrusion clamping module includes a first clamping template 6408 fixed to the inner wall of the first housing side plate 6401, and a second clamping template 6409 fixed to the left-right moving clamping linkage plate 6406 and arranged opposite to the first clamping template 6408. The fork stem 100 is placed between the first clamping template 6408 and the second clamping template 6409 and is punched by a hydraulic punching machine 6416. Additionally, the second extrusion clamping module includes a fourth clamping template 6411 fixed to the inner wall of the second housing side plate 6402, and a third clamping template 6410 fixed to the left-right moving clamping linkage plate 6406 and arranged opposite to the fourth clamping template 6411. The third clamping template 6410 and the fourth clamping template 6411 clamp the fork stem 100.

[0043] Here, after the front end of the fork riser 100 enters between the first clamping template 6408 and the second clamping template 6409, the end linkage plate 6404 is pushed to the right by the compression clamping cylinder 6403. The transmission rod 6405 drives the left-right moving clamping linkage plate 6406 to move to the right, so that the first clamping template 6408 and the second clamping template 6409 come close together and clamp the fork riser 100. Then, the end of the fork riser 100 is punched by the hydraulic punching machine 6416 arranged vertically to obtain the connecting hole 102. In addition, during the chamfering process, the compression clamping cylinder 6403 moves to the left, so that the fourth clamping template 6411 and the third clamping template 6410 clamp the fork riser 100. Then, the chamfering milling module is used to perform the chamfering process. In addition, a mold hole 6417 is provided between the fourth clamping template 6411 and the third clamping template 6410, and between the first clamping template 6408 and the second clamping template 6409, so as to facilitate the chamfering milling cutter 6415 and the hydraulic punching machine 6416 to perform processing operations.

[0044] In this embodiment, the chamfering and milling module includes a longitudinal sliding assembly 6412 fixed to the inner wall of the second housing side plate 6402, a longitudinal pushing cylinder 6413 fixed to the top plate of the housing and pushing the longitudinal sliding assembly 6412 to slide longitudinally, a chamfering and milling motor 6414 disposed on the longitudinal sliding assembly 6412, and a chamfering cutter 6415 disposed at the bottom of the chamfering and milling motor 6414 and facing the front fork stem 100. The longitudinal pushing cylinder 6413 drives the chamfering and milling motor 6414 and the chamfering cutter 6415 to move up and down, and performs chamfering processing on the end of the front fork stem 100.

[0045] In this embodiment, a feeding mechanism is used to feed the fork stem 100, and a discharging mechanism is used to discharge the fork stem 100. The feeding mechanism includes a first guide rail 651 fixed to the workbench 62 and a feeding pusher 652, a first slide plate 653 slidably mounted on the first guide rail 651 and connected to the feeding pusher 652, a first support plate 654 fixed to the first slide plate 653, a feeding pusher cylinder 655 mounted on the first slide plate 653 and the first support plate 654, and a feeding pusher plate 656 located at the front end of the feeding pusher cylinder 655 and pushing the fork stem 100 from the punching and chamfering feeding support 63 into the punching and chamfering actuator 64. The feeding mechanism includes a feeding pusher 661 and a second guide rail 662 fixed on the workbench 62, a second slide plate 663 slidably mounted on the second guide rail 662 and connected to the feeding pusher 661, a second support plate 664 fixed on the second slide plate 663, a feeding pusher cylinder 665 mounted on the second support plate 664 and the second slide plate 663, a feeding pusher plate 666 at the front end of the feeding pusher cylinder 665, and two feeding ejector rods 667 at the front end of the feeding pusher plate 666. The feeding ejector rods 667 push out the front fork riser 100 between the fourth clamping template 6411 and the third clamping template 6410, and between the first clamping template 6408 and the second clamping template 6409.

[0046] In this embodiment, after the front fork riser 100 is chamfered, its front end surface has burrs or its outer diameter does not match the front fork connecting seat. Therefore, the front fork riser 100 needs to be turned. Thus, the front fork riser 100 on the feeder 3 needs to be transferred to the lathe assembly 9, and the turned front fork riser 100 is transferred to the unloading conveyor belt 8. The unloading mechanism 7 includes a support frame 701 and a truss 702 forming a portal frame shape, a longitudinal two-axis moving assembly mounted on the truss 702, a longitudinal mounting plate 710 fixed on the longitudinal two-axis moving assembly, a rotary cylinder 711 located at the lower part of the longitudinal mounting plate 710, a clamping cylinder mounting seat 712 fixed on the rotary cylinder 711, clamping cylinders 713 corresponding to the ends of the clamping cylinder mounting seats 712, and clamping claws 714 located on the clamping cylinders 713. The clamping cylinder 713 and clamping claw 714 clamp the fork stem 100, and the rotating cylinder 711 drives the clamping cylinder 713 and clamping claw 714 to swing. Here, the two clamping cylinders 713 are arranged at 180° (or two clamping cylinders arranged at 90° to 180°, with the clamping cylinder mounting base 712 adjusted similarly). The rotating cylinder 711 drives one of the clamping cylinders to move upwards (i.e., one fork stem 100 moves upwards towards the longitudinal mounting plate 710), while simultaneously driving the other clamping cylinder to move downwards (i.e., another fork stem 100 is positioned downwards below the rotating cylinder 711), thus gripping the fork stem 100 using the oriented clamping cylinders. The usage process is as follows: Here, the initial state is defined as follows: A fork riser 100 that has just completed turning is on the lathe assembly 9, and the feeder 3 conveys the fork riser 100 to be turned. One clamping cylinder 713 (labeled as clamp number one) clamps the fork riser 100 to be turned, and the other clamping cylinder 713 (labeled as clamp number two) is in an idle state. For ease of understanding, this embodiment uses clamp number one and clamp number two to describe the state.

[0047] In the first step, the truss 702 moves the first and second clamps to the position of the lathe assembly 9. The second clamp removes the fork riser 100, which has just been turned. The rotary cylinder 711 drives the two clamping cylinders 713 (i.e., the first and second clamps) to switch positions, and places the fork riser 100 (on the first clamp) onto the lathe assembly 9 for machining. At this point, the first clamp is idle, and the second clamp holds the fork riser 100 that has just been turned.

[0048] In the second step, the truss 702 moves the first clamp and the second clamp to the position of the feeder 3. The rotary cylinder 711 drives the first clamp toward the front fork riser 100 on the feeder 3 and clamps it. At this time, the first clamp holds the unprocessed front fork riser 100, and the second clamp holds the front fork riser 100 that has just been turned.

[0049] In the third step, the truss 702 moves the first clamp and the second clamp to the position of the unloading conveyor belt 8. The rotary cylinder 711 drives the clamping cylinder mounting seat 712 to swing, and the second clamp is placed at the lower part. The second clamp lowers the machined front fork riser tube 100. At this point, the second clamp is in an idle state, and the first clamp holds the unmachined front fork riser tube 100.

[0050] In the fourth step, the truss 702 moves the first and second clamps to the position of the lathe assembly 9. At this time, the lathe assembly 9 has completed the turning of the fork riser 100 in the previous cycle. The idle second clamp is used to remove the fork riser 100 that has just been turned and place it into the fork riser 100 to be turned in the next cycle, and so on. In this embodiment, during the process of the truss 702 driving the first and second clamps to move towards the feeder 3 and the unloading conveyor 8, and during the process of picking up and unloading materials at the positions of the feeder 3 and the unloading conveyor 8, the lathe assembly 9 realizes the turning of the fork riser 100. It does not require the unloading mechanism 7 to wait in the lathe assembly 9, and its processing efficiency is higher.

[0051] Here, the longitudinal two-axis moving assembly includes a third slide plate 705 fixed to the truss 702, a longitudinal cylinder mounting base 706 and a fourth slide rail 708 fixed to the third slide plate 705, a longitudinal push rod 707 fixed to the longitudinal cylinder mounting base 706, and a fourth slide plate 709 slidably disposed on the fourth slide rail 708 and connected to the longitudinal push rod 707. A longitudinal mounting plate 710 is fixed to the fourth slide plate 709.

[0052] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any changes made based on the design principles of this utility model, or any non-creative changes made on this basis, shall fall within the scope of protection of this utility model.
