Description

Technical Field

[0001] The invention belongs to the technical field of bicycle spring component assembly, and in particular relates to an automatic assembly machine for bicycle spring components. Background Art

[0002] Some high-performance bicycle front forks are usually equipped with matching spring assemblies to play a role in shock absorption and vibration reduction during riding. This bicycle front fork spring assembly is assembled from multiple parts through multiple processes. Its parts include springs, distance rubbers, rubber sheaths, lubricants, upper seats and compression rubbers, etc. The process includes first inserting distance rubbers into the springs, then putting rubber sheaths on the correct position of the springs, then applying lubricants on the surface of the springs, and then installing upper seats and compression rubbers at the ends of the springs in turn, and finally completing the assembly and discharging.

[0003] Although mechanical automation technology has developed rapidly, due to technical limitations and thinking limitations in the industry, the assembly of bicycle front fork spring components has not been fully automated. The main difficulties include:

[0004] 1) Since the inner diameter of the rubber sleeve is smaller than the overall outer diameter of the spring, mechanical operation is not as dexterous as manual operation when putting the rubber sleeve on the spring. The current mechanical device often pulls the rubber sleeve off the spring again or displaces it when resetting, which can easily cause product defects;

[0005] 2) When applying oil to the surface of the spring, the current mechanical device often applies oil unevenly or excessively, resulting in defective products and waste of lubricating oil;

[0006] 3) Since the full assembly of the bicycle front fork spring assembly requires multiple processes, the spring and its accessories need to be transferred between various workstations. However, the current mechanical devices cannot effectively guarantee the positioning accuracy of the spring and its accessories when they arrive at each workstation, which will lead to poor assembly of the product.

[0007] For this reason, the existing bicycle front fork spring assembly is still assembled manually. However, the manual assembly method is not only inefficient, labor-intensive, and costly, but also has problems such as the position of the rubber sleeve, the amount of lubricating oil, and the uniformity that cannot be kept stable during manual assembly, making it difficult to ensure quality and consistency, and sometimes there will be mis-assembly or missing assembly.

[0069] As a further preferred embodiment, the position heights of the first-stage spring silo slope 202, the second-stage spring silo slope 204 and the third-stage spring silo slope 206 are gradually increased, or the position height of the first-stage spring silo slope 202 is lower than the position height of the second-stage spring silo slope 204, and the position height of the third-stage spring silo slope 206 is flush with the position height of the second-stage spring silo slope 204.

[0070] The working principle of the spring feeding and positioning mechanism 2 is as follows:

[0071] A plurality of springs are placed in the first spring silo where the first spring silo slope 202 is located. Due to the backward inclination, the springs are stacked and arranged at the bottom of the rear end of the first spring silo slope 202, and there is always one spring on the first spring loading lifting plate 203. The first spring loading lifting plate lifting cylinder 210 drives the first spring loading lifting plate 203 to rise, thereby supporting one spring to rise. When the first spring loading lifting plate 203 rises to the highest position, the springs are automatically lifted under the action of the slope. The first spring loading lifting plate 203 is lowered to the lowest position after rolling into the second spring silo slope 204, and then the first spring loading lifting plate lifting cylinder 210 drives the first spring loading lifting plate 203 to descend to the lowest position, waiting for the next spring to be lifted. When the spring detection sensors on both sides of the second spring silo slope 204 sense that a spring has rolled onto the second spring loading lifting plate 205 at the bottom of the second spring silo slope 204, the second spring loading lifting plate lifting cylinder 211 drives the second spring loading lifting plate 205 to rise, thereby supporting a spring to rise. When the second spring loading lifting plate 205 rises to the highest position, the spring automatically rolls into the three-stage spring silo slope 206 under the action of the slope, and then the second spring loading lifting plate lifting cylinder 211 drives the second spring loading lifting plate 205 to descend to the lowest position, waiting for the second lifting of the next spring. When the spring detection sensors on both sides of the three-stage spring silo slope 206 sense that a spring has rolled onto the spring V-shaped positioning block 207 at the bottom of the three-stage spring silo slope 206, the spring V-shaped positioning block lifting cylinder 213 drives the spring V-shaped positioning block 207 to rise through the lower baffle plate 212 of the spring V-shaped positioning block, and then supports a spring to rise again until it is higher than the upper edge of the spring feeding and positioning mechanism outer frame 201, and reaches the fixed distance rubber installation station. Finally, the spring pressing cylinder 214 drives the spring pressing head 216 to descend through the spring pressing head connecting block 215, and presses the spring on the spring V-shaped positioning block 207, thereby completing the feeding and fixing of a spring, and providing spring positioning for the next fixed distance rubber installation process. Since the step-by-step feeding method is adopted, the problem of piling or jamming of springs during feeding can be prevented.

[0075] As a further preferred embodiment, the position heights of the first-level fixed-distance rubber silo slope 302, the second-level fixed-distance rubber silo slope 304 and the third-level fixed-distance rubber silo slope 306 are gradually increased, or the position height of the first-level fixed-distance rubber silo slope 302 is lower than the position height of the second-level fixed-distance rubber silo slope 304, and the position height of the third-level fixed-distance rubber silo slope 306 is flush with the position height of the second-level fixed-distance rubber silo slope 304.

[0076] The working principle of the distance rubber feeding and installation mechanism 3 is as follows:

[0077] Put a number of distance rubbers into the first distance rubber silo where the first distance rubber silo slope 302 is located. Due to the backward slope, the distance rubbers will be stacked and arranged at the rear end bottom of the first distance rubber silo slope 302, and there is always a distance rubber on the first distance rubber loading lifting plate 303. The first distance rubber loading lifting plate lifting cylinder 311 drives the first distance rubber loading lifting plate 303 to rise, and then supports a distance rubber to rise. When the first distance rubber loading lifting plate 303 rises to the highest position, the distance rubber automatically rolls into the second distance rubber silo slope 304 under the action of the slope, and then the first distance rubber The lifting cylinder 311 of the rubber loading lifting plate drives the first fixed-distance rubber loading lifting plate 303 to descend to the lowest position, waiting for the next fixed-distance rubber to be lifted. When the fixed-distance rubber detection sensors on both sides of the second-level fixed-distance rubber material bin slope 304 sense that a fixed-distance rubber has rolled onto the second fixed-distance rubber loading lifting plate 305 at the bottom of the second-level fixed-distance rubber material bin slope 304, the second fixed-distance rubber loading lifting plate lifting cylinder 312 drives the second fixed-distance rubber loading lifting plate 305 to rise, thereby supporting a fixed-distance rubber to rise. When the second fixed-distance rubber loading lifting plate 305 rises to the highest position, the fixed-distance rubber automatically rolls into the third-level fixed-distance rubber material bin under the action of the slope. The third-level fixed-distance rubber silo slope 306 is then driven by the second fixed-distance rubber loading lifting plate lifting cylinder 312 to lower the second fixed-distance rubber loading lifting plate 305 to the lowest position, waiting for the second lifting of the next fixed-distance rubber. When the fixed-distance rubber detection sensors on both sides of the third-level fixed-distance rubber silo slope 306 sense that a fixed-distance rubber has rolled onto the fixed-distance rubber V-shaped positioning block 307 at the bottom of the third-level fixed-distance rubber silo slope 306, the fixed-distance rubber V-shaped positioning block lifting cylinder 314 drives the fixed-distance rubber V-shaped positioning block 307 to rise through the lower baffle plate 313 of the fixed-distance rubber V-shaped positioning block, thereby supporting a fixed-distance rubber to rise again until it is higher than the outer frame of the fixed-distance rubber loading and installation mechanism. The upper edge of 301 reaches the distance rubber installation station, and the distance rubber limit pressure block 315 plays an upper and lower limit role on the distance rubber located on the distance rubber V-shaped positioning block 307. The distance rubber installation propulsion cylinder 317 drives the distance rubber installation push rod 318 to move rightward, thereby pushing the distance rubber located on the distance rubber V-shaped positioning block 307 to the right through the distance rubber installation guide sleeve 316 and then inserting it into the spring located on the spring V-shaped positioning block 207, thereby completing the loading and installation of a distance rubber. Finally, the distance rubber installation propulsion cylinder 317 drives the distance rubber installation push rod 318 to reset to the left, waiting for the advancement of the next distance rubber. Since the step-by-step and root-by-root loading method is adopted, the problem of stacking or jamming of the distance spring can be prevented when loading.

[0084] The working principle of the spring sheath installation mechanism 4 is as follows:

[0085] The sheath vibration plate 402 conveys the spring sheaths into the sheath straight vibration track 403 in sequence, and loads them one by one to the discharge port of the sheath straight vibration track 403 under the operation of the sheath linear vibrator 404, and then positions them.

[0086] The sheath opening six-claw chuck transverse movement cylinder 417 drives the sheath opening six-claw chuck transverse movement sliding seat 416 to move leftward along the sheath opening six-claw chuck transverse movement guide rail 415, thereby driving the sheath opening six-claw chuck 418 and the sheath supporting six-claw 419 to move leftward, and making the sheath supporting six-claw 419 extend into the spring sheath clamped by the sheath clamping claw 409 at the sheath opening station; the sheath clamping claw cylinder 408 drives the sheath clamping claw 409 to release the spring sheath, and the sheath clamping claw 409 is reset under the linkage cooperation of the sheath rotating cylinder 407 and the sheath forward movement cylinder 406, and returns to the discharge port of the sheath straight vibration track 403 to wait for clamping the next spring sheath;

[0087] The spring inner hole positioning rod lateral movement cylinder 424 drives the spring inner hole positioning rod lateral movement cylinder mounting plate 420, the spring inner hole positioning rod 426, and the support sleeve six-claw support guide sleeve lateral movement cylinder 423 to move leftward along the spring inner hole positioning rod lateral movement guide rail 421, so that the left end of the spring inner hole positioning rod 426 penetrates into the center hole of the support sleeve six-claw chuck 418 and then passes to the left from the support sleeve six-claw 419, and then the support sleeve six-claw support guide sleeve lateral movement cylinder 423 The six-claw support sleeve opening guide sleeve 428 is driven to move leftward on the spring inner hole positioning rod 426, so that the six-claw support sleeve opening guide sleeve 428 penetrates into the center hole of the six-claw support sleeve chuck 418 and opens the six-claw support sleeve 419, thereby opening the spring sleeve sleeve on the six-claw support sleeve 419, and at the same time, there is a circle of gap between the opened six-claw support sleeve 419 and the six-claw support sleeve opening guide sleeve 428, and the distance of the gap is greater than the spring diameter of the spring;

[0088] The spring handling mechanism transfers the spring to the sheath installation station, the spring clamping claw forward cylinder 412 drives the first spring clamping claw cylinder 413 to move forward, the first spring clamping claw cylinder 413 drives the first spring clamping claw 414 to clamp the spring clamped by the spring handling mechanism, and then the spring handling mechanism releases the spring and withdraws; driven by the spring transverse movement KK module servo motor 411, the spring transverse movement KK module 410 drives the spring clamping claw forward cylinder 412 and the first spring clamping claw cylinder 413 to move rightward, so that the right end of the spring is extended into the six claws 419 of the support sheath, and the six claws of the support sheath open the guide sleeve together with the spring inner hole positioning rod 426 to extend into the end hole of the right end of the spring;

[0089] Then the spring transverse shift KK module servo motor 411, the sleeve opening six-claw chuck transverse shift cylinder 417, the spring inner hole positioning rod transverse shift cylinder 424, the sleeve support six-claw opening guide sleeve transverse shift cylinder 423, and the sleeve push cylinder 430 work together.

On the other hand, the spring transverse shift KK module servo motor 411 drives the spring transverse shift KK The module drives the spring to move to the right synchronously, and at the same time, the sleeve pushing cylinder 430 drives the sleeve pushing plate 431 to be gradually pushed out to the left to prevent the spring sleeve from moving to the right. This is equivalent to keeping the position of the stretched spring sleeve stationary, and the spring automatically extends into the stretched spring sleeve from left to right. When the spring moves to the right to the correct position of the spring sleeve, the six-claw support sleeve guide sleeve 428 completely withdraws from the sleeve stretching six-claw chuck 418, the spring inner hole positioning rod 426 also completely withdraws from the right end hole of the spring, and the six-claw support sleeve 419 also withdraws from the right end of the spring, so that the spring sleeve is tightly installed to the correct position on the outside of the spring.

[0095] The linear transport mechanism 8 transfers the spring with the fixed distance rubber and the sheath from the sheath installation station to the oil brushing station, and sheathes the right end of the spring on the oil brushing top fixed end top 508. The spring rotating motor transverse movement cylinder 502 drives the spring rotating motor 503 and the oil brushing top movable end top 504 to move to the right along the spring rotating motor transverse movement guide rail 505, so that the oil brushing top movable end top 504 is inserted into the left end of the spring and the spring is clamped on the oil brushing station. The spring rotating motor 503 drives the oil brushing top movable end top 504 to rotate. Since the oil brushing top fixed end top 508 is installed on the bearing, it drives the spring to rotate on the oil brushing station. The oil brushing head displacement cylinder 513 drives the oil brushing head 514 to move obliquely downward along the oil brushing head displacement guide rail 515, so that the oil brushing head 514 contacts the outer surface of the rotating spring.

The grease is evenly applied to the surface of the spring by rotating and moving left and right, so as to complete the oiling. Finally, the oiling mechanism is reset;

[0121] 8. The linear transport mechanism 8 starts to work, clamps the oiled spring, and transports it from the oiling station to the upper seat and compression rubber installation station.
