Description

Technical Field

[0001] This invention belongs to the technical field of steering column assembly equipment, and specifically refers to an automatic steering column assembly equipment. Background Technology

[0002] Currently, front forks are commonly found in motorcycles, electric vehicles, or bicycles. They typically have fixed shock absorbers at both ends to form steering columns, which are mainly used to buffer and steer when in contact with ground obstacles.

[0003] like Figure 1 As shown, the steering column 9 assembly is formed by combining the front fork 90 and the shock absorber 91. The steering shaft 92 is fixed in the middle of one end of the front fork 90, and front fork notches 93 are formed on both sides for the end of the shock absorber 91 to be inserted. The size of the front fork notches 93 is adjusted by bolts to lock the end of the shock absorber 91.

[0004] Because the steering column assembly has an irregular shape, the traditional method involves manually fixing the fork to the fixture, manually inserting the two shock absorbers into the fork notch, and then securing them with bolts using a hand-held pneumatic tool. This human error introduces many inconsistencies, resulting in poor calibration results and a low yield rate. Summary of the Invention

[0053] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1 — Figure 11 :

[0054] An automated steering column assembly device includes a tooling device 1 and a pressing device 2.

[0055] The tooling device 1 includes several tooling mechanisms 3 circumferentially fixed on the turntable 30. Each tooling mechanism 3 includes two opposing rotating seats 31 fixed on the turntable 30. A rotating body 32 is rotatably connected between the two rotating seats 31. The middle part of the rotating body 32 is provided with a mounting hole 320 for inserting the directional shaft 92. A tooling booster cylinder 33 is provided on one side of the turntable 30. The piston rod of the tooling booster cylinder 33 is fixed with a shock-absorbing plate 34 that pushes the shock absorber 91 into the front fork notch 93.

[0056] The pressing device 2 includes a frame assembly 20 located on one side of the tooling device 1. A lifting back plate 21 is provided above the frame assembly 20. A screw motor support plate 22 driven by a lead screw and a jaw bit lifting slide plate 23 are sequentially mounted on the front side of the lifting back plate 21 via a longitudinal slide rail from top to bottom. Two sets of universal drive bit mechanisms 24 are provided on the screw motor support plate 22. The front side of the jaw bit lifting slide plate 23 synchronously drives the bit sleeves 240 in the two universal drive bit mechanisms 24 to rotate in opposite directions and adjust the spacing through a pitch moving mechanism 25.

[0057] The pitch moving mechanism 25 includes a longitudinal mounting plate 250 fixed to the front side of the jaw bit lifting slide plate 23. An angle-adjusting support rod 251, which moves up and down via a longitudinal lead screw, is provided on the front side of the longitudinal mounting plate 250. A transverse slide rail 230 is fixed to the front end of the jaw bit lifting slide plate 23. Two variable-diameter slide plates 231, which slide laterally, are provided on the front side of the transverse slide rail 230. A drive wheel 2320, driven by a synchronous belt motor 232, is provided on one side of the transverse slide rail 230, and a driven wheel, which rotates synchronously by a synchronous belt, is provided on the other side. The rear end of the wheel 2321 and the variable diameter slide plate 231 is provided with a timing belt pressure block 2310 for fixing to the timing belt. Both of the bit sleeves 240 are fixed with rotating blocks 241. The two rotating blocks 241 are rotatably connected to the front end of the two variable diameter slide plates 231 respectively. An angle adjustment plate 242 fixed to the rear side of the rotating block 241 is provided between the rotating block 241 and the variable diameter slide plate 231. An adjustment groove 2420 is provided on the angle adjustment plate 242. The front end of the angle adjustment support rod 251 is provided with an adjustment shaft 252 that passes through the two adjustment grooves 2420.

[0058] The specific operating procedures are as follows: Figure 1 , 8 As shown in Figures 9 and 10, the operator inserts the pre-installed shock absorber 91 into the fork notch 93 and places it on the tooling device, and then inserts the steering shaft 92 into the mounting hole 320 in the rotating body 32. After that, the operator does not need to perform any installation or calibration work.

[0059] When the workpiece placed on the turntable 30 rotates to the pressing device 2, the clamp lifting slide 23 on the lifting back plate 21 controls the bit sleeve 240 in the universal drive bit mechanism 24 to move up and down. After adjusting to the required position, the bit sleeve 240 installs the bolts, which reduces the front fork notch and achieves a tight fit of the shock absorber 91.

[0060] like Figure 1 As shown, because the notch in the fork is not vertical, the screwdriver bit socket cannot be used for bolt installation vertically.

[0061] Therefore, when adjusting the width of the two batch head sleeves, such as Figure 4 , 5 As shown in Figures 6 and 7, the synchronous belt motor 232 in the pitch moving mechanism 25 drives the left and right movement of the two variable diameter slide plates 231. Specifically, one variable diameter slide plate 231 is placed above the annular synchronous belt and fixed by the synchronous belt pressure block 2310; the other variable diameter slide plate 231 is placed below the annular synchronous belt and similarly fixed by the synchronous belt pressure block 2310. When the drive pulley 2320 rotates, the upper and lower synchronous belts travel in opposite directions, causing the two variable diameter slide plates 231 to move closer together and further apart. The change in position of the variable diameter slide plates 231 causes a change in the distance between the two rotating blocks 241, thus realizing a change in the distance between the two batching head sleeves.

[0062] The synchronous adjustment of the angles of the two bit sleeves 240 is achieved by controlling the up-and-down position of the angle adjustment rod 251. Specifically, the up-and-down movement of the angle adjustment rod 251 causes the rotating blocks 241 on both sides to rotate, thereby causing the bit sleeves 240 to rotate synchronously in different directions, thus meeting the installation requirements under the inclined setting of the bolts on the fork notch 93.

[0063] The purpose of the tooling booster cylinder 33 in pushing the shock absorber 91 into the fork notch 93 is to ensure that the shock absorber is installed in the fork notch 93 with the same pushing distance, so as to ensure the uniformity of the height of the two shock absorbers.

[0064] After the bolts are installed, the turntable rotates to move away from the press-fitting device, and the steering column assembly can then be moved.

[0065] Preferably, the universal drive bit mechanism 24 includes a universal motor 243 fixed on the screw motor support plate 22. Two sets of universal joints 2430 are fixed on the output shaft of the universal motor 243. A telescopic rod 2431 with a return spring is provided between the two universal joints 2430. The top of the bit sleeve 240 is fixed to the bottom universal joint 2430 through the drive shaft, and the bit sleeve 240 is located above the mounting notches at both ends of the front fork 90.

[0066] In the above structure, such as Figure 4 As shown, when the bit sleeve 240 is at the notch 93 of the front fork, it needs to move downward to install the bolt. During the downward pressing process, the stroke of the bit sleeve 240 is short and the precision requirement is high in order to achieve accurate installation. Therefore, the telescopic rod 2431 is allowed to return to its original position quickly through the return spring, which facilitates continuous bolt installation operations.

[0067] Preferably, an upper cylinder plate 26 is slidably mounted on the longitudinal slide rail on the front side of the lifting back plate 21. The top of the lifting back plate 21 drives the upper cylinder plate 26 to rise and fall by means of a first lead screw motor 210 driving the lead screw. A longitudinal cylinder 220 is fixed on the screw motor support plate 22, and the piston rod end of the longitudinal cylinder 220 is fixed to the bottom of the upper cylinder plate 26. A lower cylinder plate 27 is slidably mounted on the longitudinal slide rail on the front side of the lifting back plate 21, located between the screw motor support plate 22 and the jaw bit lifting slide plate 23. The top of the lifting back plate 21 drives the lower cylinder plate 27 to rise and fall by means of a second lead screw motor 211 driving the lead screw. A standard cylinder 233 is fixed to the bottom of the jaw bit lifting slide plate 23, and the piston rod end of the standard cylinder 233 is fixed to the bottom of the lower cylinder plate 27.

[0068] In practical implementation, the first lead screw motor 210 and the second lead screw motor 211 control the up-and-down movement of the upper cylinder plate 26 and the lower cylinder plate 27, respectively. These are used for height adjustment of steering columns of different specifications during installation, as well as height adjustment of the telescopic rod 2431. This adjustment method controls more variables, thus providing a wider range of adjustments.

[0069] Preferably, a pre-assembly frame 200 is slidably provided on the upper end of the frame assembly 20, and the lifting back plate 21 slides up and down along the pre-assembly frame 200; a first drag chain 201 is provided between the pre-assembly frame 200 and the lifting back plate 21, and a second drag chain 202 is provided between the lifting back plate 21 and the screw motor support plate 22.

[0070] In this equipment, the pre-installation frame 200 on the frame assembly 20 facilitates the installation and disassembly of all pressing mechanisms, and the cable chain is provided for easy storage of air pipes and wires.

[0071] Preferably, the bottom of the longitudinal mounting plate 250 is fixedly connected to the transverse slide rail plate 230 via a horizontal plate. A sliding support rod slider 253 is provided on the front side of the longitudinal mounting plate 250, and the end of the angle adjusting support rod 251 is fixedly connected to the support rod slider 253. A lead screw for adjusting the lifting is adapted on the support rod slider 253, and a lead screw driven wheel 254 is fixed on the top of the lead screw. An angle adjusting motor 255 is provided on the rear side of the longitudinal mounting plate 250 and fixed on the jaw bit lifting slide plate 23. The top of the angle adjusting motor 255 drives the lead screw driven wheel 254 to rotate by means of a pulley.

[0072] In the above implementation process, such as Figure 5 As shown, the angle adjustment motor 255 drives the driven wheel 254 of the lead screw to rotate, which in turn drives the slider of the support rod to move up and down along the lead screw. The angle adjustment motor 255 controls the quantification of the angle adjustment range to suit different angle requirements.

[0073] Preferably, a feed pipe 244 is provided on one side of the bit sleeve 240, and a feeding mechanism 4 for feeding material through the feed pipe 244 is provided on one side of the frame assembly 20. The feeding mechanism 4 includes a pusher assembly 40 and a conveyor assembly 41. The pusher assembly 40 includes a distributor 401 fixed on the pusher base plate 400, and a straight vibrator guide plate assembly 402 is fixed on one side of the distributor 401. The conveyor assembly 41 includes a feeding bin 410 provided on one side of the straight vibrator guide plate assembly 402, and the feed pipe 244 conveyed by a pneumatic tool is connected to one side of the feeding bin 410.

[0074] like Figure 1 and Figure 11 As shown, the feeding mechanism 4 also includes a housing, in which the pushing group and the conveying group are placed. The bolts are continuously fed by the distributor and vibrated by the straight vibrator guide plate group 402 to the feeding bin. Finally, they are pneumatically conveyed to the feed pipe 244 to meet the feeding requirements of the bit sleeve.

[0075] Preferred, such as Figure 9 and Figure 10 As shown, a U-shaped support frame 35 is provided on one side of the rotating body 32. A rubber pad 36 perpendicular to the surface of the support frame 35 is fixed on one side of the support frame 35. The support frame 35 is provided with symmetrical mounting holes 350 and mounting grooves 351. The middle part of the rubber pad 36 is fixed in the mounting hole 350 or mounting groove 351 by bolts.

[0076] During the fixing of the steering column, the rubber pads 36 on the support frame 35 serve to support the fork 90, allowing the steering column to be fixed more stably by gravity. Since steering columns of different sizes and specifications may exist, the width and position of the fork 90 may also vary. In actual use, the position of the rubber pads can be adjusted according to the dimensions.

[0077] Preferably, the piston rod end of the tooling booster cylinder 33 is fixed with an upper mold connecting seat 10, and a connecting rod 11 is fixed on the side of the upper mold connecting seat 10 away from the piston rod of the tooling booster cylinder 33. The other end of the connecting rod 11 is provided with an upper pressure sleeve 12 for the front fork 90 to abut against each other. Allowing the side walls of the front fork to abut against each other is to further enhance stability before the installation bolts are installed.

[0078] Preferably, a large rotating wheel 37 is fixed to the bottom of the turntable 30, a turntable frame 38 is fixed to the bottom of the turntable 30, a turntable motor 370 is arranged longitudinally on the turntable frame 38, and a small rotating wheel 371 that drives the large rotating wheel 37 to rotate is fixed to the top of the turntable motor 370.

[0079] In the above structure, the turntable frame 38 is used for overall support. After the turntable motor 370 drives the small wheel to rotate, the large wheel 37 can realize the position change of the tooling mechanism 3, and also provide convenience for processing operations in different directions.

[0080] Preferably, the tooling mechanism 3 consists of six sets, and a cantilever control box 39 is provided in the middle of the turntable 30.

[0081] During implementation, such as Figure 2 and Figure 3 As shown, the pressing device is one of the processes in this tooling mechanism 3. Different rotation directions and quantities can provide assembly space and assembly sequence for different processes. Furthermore, the data parameters are adjusted using the cantilever control box 39 in the middle, resulting in high overall space utilization and simpler operation.

[0082] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
