Description

Technical Field

[0001] This invention relates to the field of anti-lock braking system (ABS) assembly technology, and more particularly to an eccentric shaft press-fitting device for ABS. Background Technology

[0002] like Figure 18 As shown, the existing eccentric shaft assembly for anti-lock braking systems includes an eccentric wheel 7, a drive shaft 8, and a bearing 9. The drive shaft 8 is press-fitted into the eccentric hole of the eccentric wheel 7; the bearing 9 is press-fitted onto the eccentric wheel 7. Currently, during the press-fitting process of the eccentric shaft assembly, the press-fitting between the eccentric wheel 7 and the drive shaft 8 is done in one area. The two parts are manually placed into the press-fitting station, then press-fitted by a press-fitting machine, and finally removed manually. The press-fitting between the drive shaft 8 and the bearing 9 is done in another area. The two parts are also manually placed into the press-fitting station, then press-fitted by a press-fitting machine, and finally removed manually. This manual loading and positioning is labor-intensive, time-consuming, and requires significant manpower. Furthermore, the assembled eccentric wheel 7 and drive shaft 8 need to be manually transported to the bearing 9 between the two areas before the bearing 9 is assembled. This intermediate transport consumes manpower and resources, greatly reducing production efficiency and ultimately resulting in low production efficiency for the eccentric shaft assembly, impacting the overall economic benefits of production. Summary of the Invention

[0003] The present invention addresses the problem that in the existing press-fitting process of eccentric shaft assemblies for anti-lock braking systems, each step of the press-fitting process operates independently, requiring manual handling and transportation between each step, which is time-consuming and labor-intensive. Furthermore, each step requires manual placement and positioning of parts, resulting in high labor intensity and costs. The invention provides an eccentric shaft press-fitting device for anti-lock braking systems that achieves automated press-fitting of eccentric shaft assemblies, eliminating the need for manual intervention, saving time and labor, and removing intermediate transportation steps. This significantly improves press-fitting efficiency and ensures press-fitting consistency.

The second eccentric wheel transfer spring 3292 can ensure complete adsorption and proper adsorption when the eccentric wheel 7 is picked up, preventing it from falling during the transfer process or from being inaccurate in position during the transfer, thereby improving the transfer accuracy and stability during the transfer process. At the same time, it can better cooperate with the eccentric wheel positioning post 334 during positioning, making it easier for the eccentric wheel positioning post 334 to be inserted into the eccentric hole of the eccentric wheel 7.The eccentric wheel transfer assembly 32 ensures that the incoming eccentric wheel 7 is picked up and transferred, while also preventing damage to the eccentric wheel 7 during the picking and transfer process, thus ensuring the integrity of the eccentric wheel 7 and further improving the transfer accuracy and efficiency of the eccentric wheel 7, thereby further improving the pressing efficiency.

[0042] like Figure 7 As shown, the eccentric wheel positioning assembly 33 includes an eccentric wheel positioning bracket 330, an eccentric wheel positioning motor 331, an eccentric wheel drive shaft 332, an eccentric wheel positioning shaft 333, and an eccentric wheel positioning column 334.

[0043] When the eccentric wheel feeding mechanism 3 is working, the eccentric wheel 7 is first conveyed to the eccentric wheel feeding connecting sleeve 314 through the eccentric wheel feeding vibratory plate 312 on the eccentric wheel feeding assembly 31 via the connecting pipe. Then, the eccentric wheel feeding cylinder 315 drives the eccentric wheel feeding hole 3161 on the eccentric wheel feeding pusher 316 to move below the eccentric wheel feeding connecting sleeve 314, so that one eccentric wheel 7 falls into the eccentric wheel feeding hole 3161. The eccentric wheel feed pusher 316 is pushed back above the eccentric wheel push rod 319. Air is introduced through the push air hole 310, causing the eccentric wheel push rod 319 to rise, pushing the eccentric wheel 7 upward into the eccentric wheel discharge stepped hole 3132. At this time, the eccentric wheel horizontal transfer slide 321 and the eccentric wheel lifting transfer slide 323 on the eccentric wheel transfer assembly 32 work together to move the eccentric wheel suction head 328 to the eccentric wheel 7. The mandrel 325 is pressed down, and the eccentric wheel transfer suction hole 3271 draws air in, sucking the eccentric wheel 7 into the eccentric wheel suction head 328 and transferring it to the eccentric wheel positioning assembly 33. By lowering the eccentric wheel 7 to the eccentric wheel positioning pin 334 of the eccentric wheel positioning assembly 33, the eccentric wheel 7 applies pressure to the eccentric wheel positioning pin 334. The eccentric wheel positioning motor 331 drives the eccentric wheel drive shaft 332 to rotate, thereby causing the eccentric wheel positioning shaft 333 to drive the eccentric wheel positioning pin 334 to rotate. Finally, the eccentric wheel positioning pin 334 is inserted into the eccentric hole of the eccentric wheel 7. Then, the eccentric wheel positioning motor 331 rotates the eccentric hole of the eccentric wheel 7 to the designated position. Finally, the eccentric wheel transfer assembly 32 transfers the eccentric wheel 7 to the eccentric wheel positioning hole 2392 of the station carrier 23 of the eccentric block loading station 221, thereby completing the automated positioning and loading of the eccentric wheel 7.

The drive shaft feeding assembly 41 facilitates the feeding of drive shafts 8 one by one. During the feeding process, since one end of the drive shaft 8 has a thread and the other end does not, the different signals fed back from the two ends of the drive shaft 8 by the photoelectric sensor can identify the positive and negative orientation of the drive shaft 8, thereby accurately ensuring the feeding of the drive shaft 8 and further improving the feeding efficiency and accuracy of the drive shaft 8.

[0045] like Figure 11 and Figure 12As shown, the drive shaft press-fit assembly 42 includes a drive shaft press-fit base 421, a drive shaft press-fit bracket 422, a drive shaft press-fit positioning cylinder 423, a drive shaft press-fit bottom support 424, and a drive shaft top press-fit module.

The drive shaft press-fit positioning cylinder 423 is mounted on the drive shaft press-fit base 421, and the telescopic rod of the drive shaft press-fit positioning cylinder 423 is fixedly connected to the drive shaft press-fit bracket 422, thereby enabling the drive shaft press-fit bracket 422 to move and be positioned as a whole. The drive shaft press-fit bottom support 424 is set on the base plate of the drive shaft press-fit bracket 422; the drive shaft press-fit base 421 is also provided with a drive shaft waste bracket 4211; the drive shaft waste bracket 4211 is provided with a drive shaft waste box 4212, and the drive shaft waste box 4212 facilitates the direct recycling of the drive shaft 8 that is detected to be installed in reverse, thereby preventing reverse installation. The top press-fit module for the drive shaft includes a drive shaft press-fit cylinder 426, a drive shaft top press-fit support plate 427, a drive shaft top press-fit center rod 428, and a drive shaft press pin 429. The drive shaft press-fit cylinder 426 is mounted on the top plate of the drive shaft press-fit bracket 422. The telescopic rod of the drive shaft press-fit cylinder 426 passes through the top plate of the drive shaft press-fit bracket 422 and is connected to the drive shaft press-fit head 4261. The top press-fit support plate 427 is located in the middle of the drive shaft press-fit bracket 422.

The drive shaft pressure pin 429 is connected to the bottom of the center rod 428 at the top of the drive shaft, and the drive shaft connecting sleeve 4283 is fixedly connected to the pressure pin positioning sleeve 4291; the pressure pin positioning sleeve 4291 is provided with a pressure pin positioning hole; the drive shaft pressure pin 429 is longitudinally limited in the pressure pin positioning hole; the pressure pin positioning sleeve 4291 is provided with a drive shaft feeding channel 4292; the upper end of the drive shaft feeding channel 4292 is connected to the upper end of the drive shaft discharge pipe 417 through a connecting pipe, and the lower end of the drive shaft feeding channel 4292 is connected to the lower part of the pressure pin positioning hole.The connecting pipe facilitates the suction of the drive shaft 8 from the drive shaft discharge pipe 417 into the drive shaft feed channel 4292, thereby entering the pressure pin positioning hole. The drive shaft pressing assembly 42 can easily judge the incoming drive shaft 8. After judgment, the reverse drive shaft 8 falls directly into the drive shaft waste box 4212, and the drive shaft 8 in the correct direction is pressed into the eccentric wheel 7, further improving the pressing efficiency of the drive shaft 8.

[0046] When the drive shaft feeding assembly mechanism 4 is working, the drive shaft 8 is fed by the drive shaft vibratory plate 412 and enters the drive shaft connecting sleeve 414 through the connecting pipe. The drive shaft feeding cylinder 415 drives the drive shaft feeding hole 4161 on the drive shaft feeding push plate 416 to move below the drive shaft connecting sleeve 414, causing one drive shaft 8 to fall into the drive shaft feeding hole 4161. The drive shaft feeding cylinder 415 then drives another drive shaft 8 to move below the drive shaft discharge pipe 417. The direction detection sensor 419 feeds a signal to determine whether the direction of the drive shaft 8 is correct. Air is introduced through the drive shaft discharge air hole 4171 to blow the drive shaft 8 from the drive shaft feeding hole 4161 into the drive shaft discharge pipe 417 and transport it into the drive shaft feeding channel 4292. If the direction is reversed, it will directly enter the pressure needle positioning hole. Since there is a gap between the drive shaft 8 and the inner wall of the pressure needle positioning hole, With sufficient friction, the drive shaft 8 cannot fall directly. The drive shaft 8 is pressed into the drive shaft waste box 4212 by the top press-fit module. If the direction is correct, the drive shaft press-fit positioning cylinder 423 drives the drive shaft press-fit bracket 422 to move to the drive shaft loading station 222, and the drive shaft press-fit bottom support 424 is supported under the station carrier 23. The top press-fit module is aligned above the station carrier 23 where the eccentric wheel 7 is placed. The drive shaft press-fit cylinder 426 presses down onto the top press-fit center rod 428. The top press-fit center rod 428 drives the drive shaft press pin 429 to press down the drive shaft 8.

The bearing feeding rods 513 are vertically arranged, and any one bearing feeding rod 513 is located between two adjacent bearing feeding gaps 5121. This facilitates the bearing feeding module to push the multiple bearings sleeved on the bearing feeding rods 513 upwards, thereby facilitating the bearing transfer assembly 52 to grab and transfer the bearing 9 at the top of the bearing feeding rods 513. The bearing pushing module includes a bearing pushing bracket 514, a bearing pushing motor 515, a bearing pushing drive wheel 516, a bearing pushing driven wheel 517, a bearing pushing synchronous belt 518, and a bearing pushing plate 519.

During feeding, the bearing pusher plate 519 is pushed upward, thereby grabbing and transferring the bearings 9 one by one. By cooperating with the bearing turntable module and the bearing pusher module, it is further ensured that only one bearing 9 is grabbed at a time, and the feeding efficiency of bearings 9 is further improved.

[0048] like Figure 16As shown, the bearing transfer assembly 52 includes a bearing transfer bracket 521, a bearing transfer slide plate 522, a bearing horizontal transfer cylinder 523, a bearing lifting transfer cylinder 524, and a bearing transfer suction head 525. The bearing transfer bracket 521 is mounted on the frame 1, and the bearing transfer slide plate 522 is horizontally slidably connected to the bearing transfer bracket 521 via a bearing transfer slide rail 520. The fixed part of the bearing lifting transfer cylinder 524 is mounted on the bearing transfer slide plate 522, and the telescopic part of the bearing lifting transfer cylinder 524 is fixedly connected to one end of the bearing transfer bracket 521.

[0049] like Figure 13 As shown, the bearing press-fit assembly 53 includes a bearing press-fit bracket 531 and a bearing press-fit cylinder 532. The bearing press-fit bracket 531 is mounted on the frame 1, and the bearing press-fit cylinder 532 is longitudinally mounted on the top plate of the bearing press-fit bracket 531. The telescopic rod of the bearing press-fit cylinder 532 passes through the top plate of the bearing press-fit bracket 531 and is connected to a bearing press head 533. The bearing feeding and assembly mechanism 5 facilitates the feeding of bearings one by one and presses each bearing 9 onto the drive shaft 8, realizing automated bearing 9 press-fitting.

[0050] When the bearing loading and assembly mechanism 5 is working, the bearing pushing motor 515 drives the bearing pushing drive wheel 516 to rotate. This, in conjunction with the bearing pushing driven wheel 517 and the bearing pushing synchronous belt 518, moves the bearing pushing plate 519 below the bearing loading rotary disc 512. Multiple sets of bearings 9 are then respectively mounted on each bearing loading rod 513. One of the bearing loading rods 513 rotates and moves to the bearing pushing U-shaped opening 5191 on the bearing pushing plate 519. The bearing transfer assembly 52, through the bearing horizontal transfer cylinder 523 and the bearing lifting transfer cylinder 524, moves the bearing transfer suction head 525 above the bearing loading rod 513 on the bearing pushing plate 519. The first bearing 9 at the top of the bearing loading rod 513 is then picked up and transferred to the bearing loading station 22 via the bearing transfer suction port 5251 on the bearing transfer suction head 525. On the bearing positioning hole 2391 of the workstation carrier 23, the bearing pressing cylinder 532 on the bearing pressing assembly 53 drives the bearing pressing head 533 to press down, pressing the bearing 9 onto the eccentric wheel 7. When a second bearing 9 needs to be picked up, the bearing pushing plate 519 is moved up by the bearing pushing motor 515, so that the bearing originally located in the second position rises to the first position. Then, the pressing is carried out in sequence according to the above operation. When all the bearings 9 on one bearing loading rod 513 have been transferred, the bearing pushing plate 519 is moved to the underside of the bearing loading rotary table 512. The bearing loading rotary table motor 511 drives the bearing loading rotary table 512 to rotate, so that another bearing loading rod 513 full of bearings 9 moves to the bearing pushing U-shaped opening 5191 of the bearing pushing plate 519.

The feeding mechanism 6 automatically picks up and transfers the press-fitted eccentric shaft assembly, eliminating the need for manual loading and unloading and greatly improving the efficiency of automatic feeding.

[0052] When the unloading mechanism 6 is working, the unloading horizontal transfer cylinder 63 drives the unloading transfer slide plate 62 to move horizontally and position it above the workstation carrier 23 of the unloading station 224. The unloading lifting transfer cylinder 64 drives the unloading claw 66 on the unloading lifting plate 65 to move downward, so that the unloading claw 66 can grip the eccentric shaft assembly that has been pressed on the workstation carrier 23. Then, the unloading lifting transfer cylinder 64 and the unloading horizontal transfer cylinder 63 work together to transfer the pressed eccentric shaft assembly to the designated unloading position.
