Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of brake disc assembly, in particular to an automatic assembly equipment for locomotive brake disc. BACKGROUND

[0002] In the existing assembly process of locomotive brake disc (for train), a connecting bolt is needed to be connected in each mounting hole on the brake disc, and after the connecting bolt is connected, the brake disc with the bolt is connected to the train wheel of the train, so as to assemble the brake disc to the train wheel to realize the braking effect.

[0003] In the existing assembly process, a sleeve is first sleeved on the bolt by manual operation, the bolt is inserted into the mounting hole of the brake disc from the bottom of the brake disc, and then another sleeve is manually sleeved on the bolt from the top of the brake disc to the bottom, so that the two sleeves are located on the upper and lower sides of the brake disc, and finally the nut is tightened on the bolt by manual operation, and the bolt is tightened on the brake disc through the thread cooperation between the nut and the bolt. At present, the assembly is carried out by manual operation, which is time-consuming and laborious, and the assembly consistency cannot be guaranteed. Moreover, during the nut tightening process, the brake disc plays a very important role in the train braking process, and the safety factor to be considered is very high, so the precision requirement of the brake disc assembly is very high, and the two pre-tightening and the last fixed tightening mode are required, and the specified tightening sequence is also required. During the manual assembly process, assembly omission or skipping of pre-tightening for the sake of convenience will affect the quality of the brake disc assembly. In summary, the manual assembly method is not only low in efficiency, but also cannot guarantee the assembly quality. SUMMARY

[0004] The present application solves the technical problem that in the existing assembly process of locomotive brake disc, the bolt, nut and sleeve need to be assembled on the brake disc by manual operation, resulting in low assembly efficiency and assembly quality. The present application provides an automatic assembly equipment for locomotive brake disc, which can automatically assemble the bolt, nut and sleeve on the brake disc, save time and labor, and improve the assembly efficiency and assembly quality.

[0005] For the purpose of the present application, the following technical solutions are adopted:

[0006] An automated assembly device for locomotive brake discs includes a loading device, a transfer device, a bolt lifting device, a nut tightening device, and a brake disc rotation and positioning device. The brake disc is placed on the brake disc rotation and positioning device, and the mounting holes on the brake disc are rotated to the assembly station. The loading device includes a loading and positioning mechanism, an oil tank, and a loading carrier. The loading carrier, containing bolts, nuts, and sleeves, is placed on the loading and positioning mechanism. The loading and positioning mechanism drives the loading carrier into the oil tank for oil immersion. After immersion, the loading carrier is removed from the oil tank to drain and await transfer. The transfer device is used to transfer the brake discs one by one. The bolts, nuts, and sleeves on the loading carrier are transferred to the bolt lifting device, which moves the bolts below the assembly station and pushes them into the mounting holes at the assembly station. The sleeves are then transferred to the mounting holes of the brake disc at the assembly station and fitted onto the bolts. The nuts are transferred to the nut tightening device, which moves the nuts into the mounting holes at the assembly station and tightens them onto the bolts, thus fixing the bolts onto the brake disc. This facilitates the subsequent connection of the bolts on the brake disc to the train wheels, enabling braking during train operation. This equipment lubricates the bolts, nuts, and sleeves before assembling them onto the brake disc, ensuring smoother assembly. It also automates the assembly of bolts, nuts, and sleeves onto the brake disc, improving consistency and efficiency, reducing human error, and ultimately enhancing assembly quality.

[0007] Preferably, the brake disc rotation positioning device includes a rotation positioning bracket, a rotation drive motor assembly, a central positioning disk, a rotation drive disk, a rotation positioning disk, and a brake disc carrier. The rotation drive motor assembly is longitudinally arranged on the rotation positioning bracket. The central positioning disk is horizontally arranged on the top of the rotation positioning bracket. A central positioning hole is provided at the center of the central positioning disk. The drive shaft of the rotation drive motor assembly passes through the central positioning hole and is connected to a drive connector. The rotation drive disk is connected to the drive connector, and the drive connector drives the rotation drive disk to rotate. The brake disc carrier is connected above the rotation drive disk, and the rotation drive disk drives the brake disc carrier to rotate. A brake disc placement annular groove is provided on the top surface of the brake disc carrier. Bolt connection holes are arranged circumferentially at intervals at the bottom of the brake disc placement annular groove. The bolt connection holes correspond to the mounting holes on the brake disc. A positioning disk limiting annular groove is provided on the bottom surface of the brake disc carrier. The rotation positioning disk is limited within the positioning disk limiting annular groove and placed on the rotation drive disk. Bolt positioning holes corresponding to the bolt connection holes are provided on the rotation positioning disk. This device facilitates the placement of the brake disc within the brake disc mounting ring groove, and uses locating pins to position the brake disc relative to the mounting ring groove, thereby aligning the mounting holes on the brake disc with the bolt connection holes. Furthermore, by rotating the positioning plate to align the bolt positioning holes with the bolt connection holes, the bolt connection holes are moved one by one to the assembly station via a rotary drive motor to rotate the brake disc, improving the accuracy and efficiency of the positioning process. It also facilitates the assembly of the brake disc with bolts, nuts, and sleeves.

[0008] Preferably, the rotary positioning bracket is provided with positioning disc positioning assemblies on its front, left, and right sides. Each positioning disc positioning assembly includes a positioning disc positioning cylinder and a positioning disc positioning rod. The positioning disc positioning cylinder is arranged longitudinally, and the positioning disc positioning rod is longitudinally connected to a telescopic rod at the top of the positioning disc positioning cylinder. The top of the positioning disc positioning rod extends through the bolt positioning hole of the rotary positioning disc and into the bolt connection hole of the brake disc carrier, so that the brake disc carrier is longitudinally aligned with the rotary positioning disc. The positioning disc positioning assembly facilitates the positioning of the rotary positioning disc and ensures that the bolt positioning hole of the rotary positioning disc is aligned with the bolt connection hole of the brake disc carrier, thereby ensuring that the rotary positioning disc and the brake disc carrier are aligned. This facilitates the precise movement of the mounting holes of each brake disc to the assembly station, and further facilitates the precise assembly of bolts, nuts, and sleeves with the brake disc, improving assembly efficiency and accuracy.

By placing the loading carrier equipped with bolts, nuts, and sleeves on the loading connecting plate and limiting the loading carrier with the carrier limit block to prevent displacement during movement, the loading connecting plate descends into the oil storage tank to facilitate oil immersion lubrication of the bolts, nuts, and sleeves on the loading carrier, which is convenient for subsequent assembly. After immersion, the loading connecting plate is raised, and the lubricating oil brought up is allowed to drip into the oil storage tank through the oil leakage holes of the plate and the carrier, thus facilitating the draining of lubricating oil from the bolts, nuts, and sleeves on the loading carrier and preventing lubricating oil from dripping everywhere during assembly and transfer.

[0010] Preferably, the loading lifting drive assembly includes a lifting drive cylinder and a lifting drive connecting plate; the lifting drive cylinder is longitudinally arranged on the loading lifting bracket; the lifting drive connecting plate is connected to the telescopic rod at the top of the lifting drive cylinder; and a loading lifting slide rail is provided between the lifting drive connecting plate and the loading lifting bracket; the loading connecting plate is L-shaped; the vertical plate of the loading connecting plate is fixedly connected to the lifting drive connecting plate, and the horizontal plate of the loading connecting plate is horizontally arranged and located above the oil immersion opening; the oil leakage holes of the plate are respectively located on the vertical plate and the horizontal plate of the loading connecting plate; the first oil leakage hole includes multiple longitudinal strip holes. The loading carrier has multiple horizontal strip-shaped holes; multiple longitudinal strip-shaped holes are arranged vertically at intervals on the vertical plate of the loading connecting carrier; multiple horizontal strip-shaped holes are arranged horizontally at intervals on the horizontal plate of the loading connecting carrier; multiple carrier support horizontal plates are arranged at intervals in the front-to-back direction on the loading carrier; each carrier support horizontal plate has horizontally spaced holding slots; an oil leakage horizontal groove is formed between two adjacent carrier support horizontal plates; multiple carrier oil leakage holes are arranged horizontally at intervals on each oil leakage horizontal groove; the number of carrier oil leakage holes on each oil leakage horizontal groove is the same as the number of horizontal strip-shaped holes and they are correspondingly connected. The lifting driving connecting plate is raised and lowered by a lifting driving cylinder, which facilitates lifting and moving. The L-shaped loading connecting carrier facilitates support for the loading carrier and can also connect well with the lifting driving connecting plate, thereby ensuring that the loading carrier can move stably in the lifting and lowering direction.

[0011] Preferably, the transfer device is a transfer robot arm, which is equipped with cylinder grippers. The inner walls of the two grippers of the cylinder grippers are symmetrically provided with stepped concave surfaces. Each stepped concave surface includes a triangular notch at the bottom for clamping nuts and an arc-shaped notch at the top for clamping sleeves. Using a transfer device in the form of a transfer robot arm facilitates the gripping of bolts, nuts, and sleeves from the loading device. The arc-shaped notch facilitates the clamping of bolts and sleeves, and the triangular notch facilitates the clamping of hexagonal nuts.

[0012] Preferably, the bolt lifting device includes a bolt support base, a bolt horizontal positioning mechanism, a bolt lifting positioning mechanism, and a bolt carrier. The bolt horizontal positioning mechanism is horizontally mounted on the bolt support base, and the bolt lifting positioning mechanism is mounted on the drive unit of the bolt horizontal positioning mechanism, and is used to drive the bolt lifting positioning mechanism for horizontal movement and positioning.

The top of the bolt carrier is provided with a regular polygonal bolt groove, and the opening of the bolt groove faces upward. The number of sides of the regular polygonal bolt groove is greater than the number of sides of the regular polygonal bolt head at the bottom of the bolt. This device facilitates the longitudinal placement of the bolt through the bolt groove on the bolt carrier, and the bolt groove can limit the hexagonal bolt head at the bottom of the bolt, preventing the bolt from rotating, thereby facilitating smooth tightening of the nut onto the bolt later.

[0013] Preferably, the bolt horizontal positioning mechanism includes a bolt horizontal positioning cylinder and a bolt horizontal positioning frame; the bolt horizontal positioning cylinder is horizontally mounted on the bolt support, and the bolt horizontal positioning frame is connected to the telescopic rod of the bolt horizontal positioning cylinder, with the bottom of the bolt horizontal positioning frame being horizontal; and at least one bolt horizontal positioning slide rail is provided between the bottom of the bolt horizontal positioning frame and the bolt support. The bolt lifting positioning mechanism includes a bolt lifting positioning cylinder and a bolt lifting positioning frame; the bolt lifting positioning cylinder is longitudinally mounted at the front of the bolt horizontal positioning frame; the bolt lifting positioning frame is connected to the telescopic rod of the bolt lifting positioning cylinder, and a bolt lifting positioning slide rail is provided between the rear of the bolt lifting positioning frame and the front of the bolt horizontal positioning frame; the top of the bolt horizontal positioning frame is horizontal, and the bolt carrier is longitudinally mounted at the top of the bolt horizontal positioning frame. The bolt horizontal positioning cylinder and bolt lifting positioning cylinder facilitate horizontal and vertical movement positioning, improving the smoothness and accuracy of the movement process. This makes it easier to move the bolt to the bottom of the assembly station, insert the top of the bolt through the bolt positioning hole of the rotating positioning plate into the bolt connection hole of the brake disc carrier, wait for the sleeve to be put on the bolt, and tighten the nut on the bolt.

[0014] Preferably, the nut tightening device includes a nut tightening bracket, a nut carrier plate, a nut horizontal positioning mechanism, a nut lifting and positioning mechanism, and a nut suction and tightening mechanism.

The nut suction and tightening mechanism is mounted on the drive unit of the nut lifting and positioning mechanism, driving the nut suction and tightening mechanism for lifting and positioning. The nut suction and tightening mechanism is longitudinally aligned with the nut groove and is used to pick up the nut from the nut groove and tighten it onto the bolt during assembly. This device facilitates the placement of transferred nuts on nut slots and uses a nut sensor to detect whether a nut is in the slot. The nut is then picked up by a nut-picking and tightening mechanism, moved horizontally to above the assembly station by a nut-leveling positioning mechanism, lowered to the bolt connection hole of the brake disc carrier by a nut-lifting and positioning mechanism, and finally tightened onto the bolt by a nut-picking and tightening mechanism. This improves nut assembly efficiency and quality.

The nut tightening machine is longitudinally mounted on the nut lifting and positioning frame. The nut connecting sleeve is connected to the rotating part of the nut tightening machine, and a connecting protrusion is provided at the bottom of the nut connecting sleeve. A first pin hole is provided on the connecting protrusion. A connecting groove matching the connecting protrusion is provided on the nut suction connector. A second pin hole communicating with the first pin hole is also provided on the nut suction connector. The first pin hole and the second pin hole are fixedly connected by a shaft pin. A downward-facing regular polygonal suction groove is provided at the bottom of the regular polygonal suction groove. A magnet mounting cavity is provided between the bottom of the regular polygonal suction groove and the nut connecting sleeve. A magnet is installed in the magnet mounting cavity. The horizontal positioning cylinder and the vertical positioning cylinder for nuts facilitate horizontal and vertical positioning. The connecting sleeve and the nut suction connector facilitate connection. The magnet installed in the magnet mounting cavity facilitates the suction of the nut from the nut slot into the regular polygonal suction slot. After the nut is picked up, it is transferred to the assembly station. The nut tightening machine drives the connecting sleeve and the nut suction connector to rotate, and drives the vertical positioning cylinder to descend, so that the nut rotates and descends to tighten onto the bolt at the assembly station. This improves the accuracy and efficiency of automated nut assembly.

[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] like Figure 1 As shown, Figure 1The left side is the left side of the embodiment; Figure 1 The right side is the right side of the embodiment; Figure 1 The upper side is the upper side of the embodiment; Figure 1 The lower side is the lower side of the embodiment; Figure 1 The front side is the front side of the embodiment; Figure 1 The rear side is the rear side of the embodiment.

[0034] like Figure 1 As shown, an automated assembly equipment for locomotive brake discs includes a loading device 1, a transfer device 2, a bolt lifting device 3, a nut tightening device 4, and a brake disc rotation positioning device 5. A brake disc 6 is placed on the brake disc rotation positioning device 5, and the mounting holes on the brake disc 6 are rotated to the assembly station 50. The loading device 1 includes at least one loading positioning mechanism 11, an oil tank 12, and at least one loading carrier 14. The loading carrier 14, containing bolts 7, nuts 8, and sleeves 9, is placed on the loading positioning mechanism 11. The loading positioning mechanism 11 drives the loading carrier 14 into the oil tank 12 for oil immersion. After immersion, the loading carrier 14 is removed from the oil tank 12 to drain and await transfer. The transfer device 2 is used for... Bolts 7, nuts 8, and sleeves 9 are transferred one by one from the loading carrier 14. Bolt 7 is transferred to bolt lifting device 3 and moved to below assembly station 50 by bolt lifting device 3. Bolt 7 is then pushed into the mounting hole at assembly station 50. Sleeve 9 is transferred to the mounting hole of brake disc 6 at assembly station 50 and fitted onto bolt 7. Nut 8 is transferred to nut tightening device 4 and moved to the mounting hole at assembly station 50 by nut tightening device 4. Nut 8 is then tightened onto bolt 7, thereby fixing bolt 7 onto brake disc 6. This facilitates the subsequent connection of bolts on brake disc 6 to the train wheel, enabling braking during train operation. This equipment lubricates the bolts, nuts, and sleeves before assembling them onto the brake disc, making the assembly process smoother and more efficient. It also automatically assembles the bolts, nuts, and sleeves onto the brake disc, improving the consistency and efficiency of the assembly process, reducing human error, ensuring assembly consistency, and ultimately guaranteeing the assembly quality of the locomotive brake disc.

[0035] like Figures 2 to 5As shown, the brake disc rotation positioning device 5 can achieve non-unidirectional rotation in both forward and reverse directions. The brake disc rotation positioning device 5 includes a rotation positioning bracket 51, a rotation drive motor assembly 52, a central positioning disk 53, a rotation drive disk 54, a rotation positioning disk 55, and a brake disc carrier disk 56. The rotation drive motor assembly 52 is longitudinally mounted on the rotation positioning bracket 51 via a motor assembly bracket. The central positioning disk 53 is horizontally mounted on the top of the rotation positioning bracket 51. A central positioning hole 531 is provided in the center of the central positioning disk 53. The drive shaft 521 of the rotation drive motor assembly 52 passes through the central positioning hole 531 and is connected to a drive connector 522. The rotation drive disk 54 is connected to the drive connector 522, and the drive connector 522 drives the rotation drive disk 54 to rotate. A rotation positioning sensor 58 is provided on the inner ring of the rotation drive disk 54, which can further ensure the accurate positioning of the rotation drive disk 54 during rotation. The brake disc carrier 56 is connected above the rotary drive disc 54, and the rotary drive disc 54 drives the brake disc carrier 56 to rotate. The top surface of the brake disc carrier 56 is provided with a brake disc placement annular groove 561, which facilitates the placement of the brake disc 6. The bottom of the brake disc placement annular groove 561 is provided with bolt connection holes 562 arranged circumferentially at intervals; the bolt connection holes 562 are aligned with the mounting holes on the brake disc; the bottom surface of the brake disc carrier 56 is provided with a positioning disc limiting annular groove 563; the rotating positioning disc 55 is limited within the positioning disc limiting annular groove 563 and placed on the rotary drive disc 54; the rotating positioning disc 55 is provided with bolt positioning holes 551 corresponding to the bolt connection holes 562. This device facilitates the placement of the brake disc 6 within the brake disc placement ring groove 561. The bottom of the brake disc placement ring groove 561 is circumferentially spaced with alignment positioning holes 564 to align the mounting holes of the brake disc 6 with the bolt connection holes 562 during placement. Before placing the brake disc 6, positioning pins are inserted into the alignment positioning holes 564. When the brake disc 6 is placed into the brake disc placement ring groove 561, the positioning holes at the bottom of the brake disc 6 are aligned with the positioning pins on the alignment positioning holes 564, thus achieving precise positioning of the brake disc 6 and the brake disc carrier 56. Furthermore, positioning is achieved by rotating the bolt positioning holes 551 and bolt connection holes 562 on the positioning disc 55. This allows the bolt connection holes 562 to be moved one by one to the assembly station 50 for assembly via the rotation drive motor 52, improving the accuracy and efficiency of the positioning process. It also facilitates the assembly of the brake disc 6 with the bolts 7, nuts 8, and sleeves 9.

[0036] like Figures 2 to 5As shown, positioning disk positioning assemblies 57 are provided on the front, left and right sides of the rotating positioning bracket 51; each positioning disk positioning assembly 57 includes a positioning disk positioning cylinder 571 and a positioning disk positioning rod 572; the positioning disk positioning cylinder 571 is arranged longitudinally, and the positioning disk positioning rod 572 is longitudinally connected to the telescopic rod at the top of the positioning disk positioning cylinder 571. The top of the positioning disk positioning rod 572 extends through the bolt positioning hole 551 of the rotating positioning disk 55 to the bolt connection hole 562 of the brake disc carrier 56, so that the brake disc carrier 56 is longitudinally aligned and positioned with the rotating positioning disk 55. The positioning plate positioning assembly 57 facilitates the positioning of the rotating positioning plate 55 and enables the bolt positioning holes 551 of the rotating positioning plate 55 to align with the bolt connection holes 562 of the brake disc carrier plate 56. This ensures that the rotating positioning plate 55 and the brake disc carrier plate 56 are aligned, making it easier to accurately rotate the mounting holes of the brake discs 6 one by one to the assembly station 50. This, in turn, facilitates the precise assembly of the bolts 7, nuts 8, and sleeves 9 with the brake discs 6, improving assembly efficiency and accuracy.

[0037] like Figure 6 and Figure 7As shown, the feeding device 1 includes two feeding positioning mechanisms 11; an oil storage tank 12 is located between the two feeding positioning mechanisms 11; an oil immersion opening 121 is provided on the top surface of the oil storage tank 12; the feeding positioning mechanism 11 includes a feeding lifting bracket 111, a feeding lifting drive assembly 112, and a feeding connecting plate 113; the feeding lifting drive assembly 112 is longitudinally arranged on the feeding lifting bracket 111; the feeding connecting plate 113 is connected to the drive part of the feeding lifting drive assembly 112, and the feeding connecting plate 113 is located above the oil immersion opening 121, and the feeding lifting drive assembly... 112 is used to drive the loading connecting plate 113 to descend into the oil storage tank 12 or rise away from the oil storage tank 12; the loading connecting plate 113 is provided with multiple plate oil leakage holes 114; the loading connecting plate 113 is provided with multiple carrier limiting blocks 115; the shape formed by all the carrier limiting blocks 115 matches the shape of the outer peripheral wall of the loading carrier 14, and limits the loading carrier 14 within the shape formed by all the carrier limiting blocks 115; the loading carrier 14 is provided with multiple carrier oil leakage holes 141; the carrier oil leakage holes 141 are connected to the plate oil leakage holes 114. By placing the loading carrier 14 equipped with bolts 7, nuts 8 and sleeves 9 on the loading connecting plate 113, a sleeve 9 is pre-fitted onto the bolts 7 of the loading carrier 14, and the bolts 7 are arranged longitudinally so that the sleeve 9 falls at the bottom. The loading carrier 14 is limited by the carrier limiting block 115 to prevent displacement during movement. The loading connecting plate 113 descends into the oil storage tank 12 to facilitate oil immersion lubrication of the bolts 7, nuts 8 and sleeves 9 on the loading carrier 14, which is convenient for subsequent assembly. After immersion, the loading connecting plate 113 is raised, and the lubricating oil brought up is allowed to drip into the oil storage tank 12 through the oil leakage holes 114 on the plate and 141 on the carrier. This facilitates the draining of lubricating oil from the bolts 7, nuts 8 and sleeves 9 on the loading carrier 14, preventing lubricating oil from dripping everywhere during assembly and transfer.

[0038] like Figure 6As shown, the loading lifting drive assembly 112 includes a lifting drive cylinder 1121 and a lifting drive connecting plate 1122. The lifting drive cylinder 1121 is longitudinally arranged on the loading lifting bracket 111. The lifting drive connecting plate 1122 is connected to the telescopic rod at the top of the lifting drive cylinder 1121. A loading lifting slide rail 1123 is provided between the lifting drive connecting plate 1122 and the loading lifting bracket 111. The loading connecting plate 113 is L-shaped. The vertical plate of the loading connecting plate 113 is fixedly connected to the lifting drive connecting plate 1122, and the horizontal plate of the loading connecting plate 113 is horizontally arranged and located above the oil immersion opening 121. The lifting drive cylinder 1121 drives the lifting drive connecting plate 1122 to move up and down, facilitating lifting and movement. Furthermore, the L-shaped loading connecting plate 113 facilitates the support of the loading carrier 14 and can also be well connected with the lifting drive connecting plate 1122, thereby ensuring that the loading carrier 14 can move stably in lifting and lowering.

[0039] like Figure 7 As shown, the oil drain holes 114 are located on the vertical plate and the horizontal plate of the loading connecting carrier plate 113, respectively; the oil drain holes 114 include multiple longitudinal strip holes 1141 and multiple horizontal strip holes 1142; the multiple longitudinal strip holes 1141 are arranged vertically at intervals on the vertical plate of the loading connecting carrier plate 113; the multiple horizontal strip holes 1142 are arranged horizontally at intervals on the horizontal plate of the loading connecting carrier plate 113; the loading carrier 1 Six carrier support horizontal plates 142 are arranged at intervals in a front-to-back direction on the loading carrier 14. Each carrier support horizontal plate 142 has horizontally spaced storage slots 143. Two rows of the six storage slots 143 are shaped to match bolts 7 for placement; two rows are shaped to match nuts 8 for placement; and two rows are shaped to match sleeves 9 for placement. This ensures that the number of bolts 7, nuts 8, and sleeves 9 are equal and arranged in an array on the loading carrier 14. An oil leakage groove 144 is formed between two adjacent carrier support horizontal plates 142. Multiple carrier oil leakage holes 141 are arranged at horizontal intervals on each oil leakage groove 144. The number of carrier oil leakage holes 141 on each oil leakage groove 144 is the same as the number of horizontal strip holes 1142 and they are correspondingly connected. The longitudinal and horizontal slots 1141 and 1142 facilitate the raising of the loading carrier plate 113, allowing lubricating oil to drip back into the oil storage tank 12. Furthermore, the carrier's drain hole 141 is aligned with the horizontal slot 1142, enabling the lubricating oil on the loading carrier 14 to drip back into the oil storage tank 12, thus facilitating the drying of the bolts 7, nuts 8, and sleeves 9 on the loading carrier 14.

The top of the bolt carrier 34 is provided with a regular polygonal bolt groove 341, and the opening of the bolt groove 341 faces upward, which facilitates the placement of the bolt head at the bottom of the bolt 7. The number of sides of the regular polygonal bolt groove 341 is greater than the number of sides of the regular polygonal bolt head at the bottom of the bolt, which facilitates the insertion of the bolt head at the bottom of the bolt 7 into the bolt groove 341, and at the same time prevents the bolt 7 from rotating, which is convenient for the subsequent assembly of the nut 8. The device facilitates the longitudinal placement of the bolt 7 via the bolt groove 341 on the bolt carrier 34, and the bolt groove 341 also limits the hexagonal bolt head at the bottom of the bolt 7, preventing the bolt 7 from rotating. This allows the nut 8 to be smoothly tightened onto the bolt 7 later.

[0042] like Figure 10 and Figure 11As shown, the bolt horizontal positioning mechanism 32 includes a bolt horizontal positioning cylinder 321 and a bolt horizontal positioning frame 322.

This device facilitates the placement of transferred nuts 8 onto nut slots 421. Nut sensors 422 detect whether nuts 8 are present in nut slots 421. Nuts 8 are picked up by nut-picking and tightening mechanisms 45, moved horizontally to above assembly station 50 by nut horizontal positioning mechanisms 43, and lowered to bolt connection holes 562 of brake disc carrier 56 by nut lifting and positioning mechanisms 44. Nuts 8 are then rotated and tightened onto bolts 7 by nut-picking and tightening mechanisms 45, thus improving the assembly efficiency and quality of nuts 8.

[0044] The nut horizontal positioning mechanism 43 includes a nut horizontal positioning cylinder 431 and a nut horizontal positioning frame 432. The nut horizontal positioning cylinder 431 is horizontally mounted on the nut tightening bracket 41, and the nut horizontal positioning frame 432 is connected to the telescopic rod of the nut horizontal positioning cylinder 431.

[0045] An automated assembly method for locomotive brake discs, utilizing the aforementioned automated assembly equipment for locomotive brake discs:

[0046] S1. Brake disc 6 placement: First, insert positioning pins into each alignment positioning hole 564 on the brake disc carrier 56 of the brake disc rotation positioning device 5. After aligning each positioning hole at the bottom of the brake disc 6 with the positioning pins, place it on the brake disc placement ring groove 561. The positioning cylinders 571 on the front, left and right positioning disc assemblies 57 drive the positioning rods 572 to rise, so that the positioning rods 572 extend through the bolt positioning holes 551 of the rotating positioning disc 55 into the bolt connection holes 562 of the brake disc carrier 56. This ensures that initially, each bolt positioning hole 551 and bolt connection hole 562 are aligned. After positioning, lower the positioning rods 572 into the bolt positioning holes 551. This ensures that when the rotating drive motor 52 drives the brake disc 6 on the brake disc carrier 56 to rotate through the rotating drive disc 54, the rotating positioning disc 55 remains fixed. This ensures that the bolt positioning holes 551 on the rotating positioning disc 55 remain stationary at the assembly station 50, ensuring the accuracy of assembly.

[0047] S2. Loading Bolts 7, Nuts 8, and Sleeves 9: Two loading carriers 14 filled with bolts 7, nuts 8, and sleeves 9 are placed on the loading connecting plates 113 of the two loading positioning mechanisms 11. A sleeve 9 is pre-fitted onto the bolts 7 on the loading carriers 14. The lifting driving cylinder 1121 on the loading positioning mechanism 11 drives the lifting driving connecting plate 1122 to rise and fall, thereby immersing the loading carriers 14 on the loading connecting plate 113 into the oil tank 12, so that the bolts 7, nuts 8, and sleeves 9 on the loading carriers 14 are lubricated with oil. After being lubricated, the loading carriers 14 are raised to drain and await transfer. In subsequent work, the two loading positioning mechanisms 11 can achieve alternating actions. When one loading carrier 14 is transferred, the other loading carrier 14 can be lubricated and drained, which can further accelerate the lubrication efficiency and loading efficiency.

[0048] S3. Transfer of bolt 7, nut 8 and sleeve 9: The bolt 7 is first picked up and transferred to the bolt groove 341 of the bolt lifting device 3 by the transfer device 2 using a transfer robot. The bolt 7 (with a sleeve 9 pre-fitted on it) on the bolt groove 341 is then transferred to the area below the assembly station 50 by the bolt lifting device 3. The bolt 7 is then pushed into the bolt connection hole 562 and inserted into the mounting hole of the brake disc 6. The other sleeve 9 on the loading carrier 14 is then picked up and transferred to the bolt connection hole 562 at the assembly station 50. The sleeve 9 is then fitted onto the bolt 7 from top to bottom, so that the two sleeves 9 are located on the upper and lower sides of the brake disc, respectively. Finally, the nut 8 is transferred to the nut groove 421 of the nut carrier plate 42 of the nut tightening device 4.

[0049] S4. Bolt 7 positioning: The bolt 7 on the bolt carrier 34 is moved horizontally to the assembly station 50 by the bolt horizontal positioning cylinder 321 on the bolt lifting device 3, and is located below the brake disc carrier 56. The bolt 7 on the bolt carrier 34 is pushed into the bolt connection hole 562 of the brake disc carrier 56 by the bolt lifting positioning cylinder 331, so that the bolt 7 is pushed into the mounting hole of the brake disc 6, and the bolt 7 is supported and prevented from rotating.

[0050] S5. Nut 8 is positioned; the nut suction connector 453 on the nut tightening device 4 moves to above the nut groove 421 of the nut carrier plate 42, and the nut lifting and positioning cylinder 441 drives the nut suction connector 453 on the nut suction and tightening mechanism 45 to descend, so that the nut suction connector 453 picks up the nut 8 in the nut groove 421. After picking it up, the nut horizontal positioning cylinder 431 drives the nut 8 to move above the assembly station 50; the nut lifting and positioning cylinder 441 drives the nut 8 to descend into the bolt connection hole 562 of the brake disc carrier plate 56 and enter the mounting hole of the brake disc 6. The nut tightening machine 451 drives the nut 8 to rotate, so that the nut 8 rotates onto the bolt 7 in the mounting hole of the brake disc 6 while descending, thereby fixing the bolt 7 to the brake disc 6.

[0051] During the assembly of the eighteen bolts 7, the mounting holes on the brake disc 6 are numbered sequentially from 101 to 118 by rotating clockwise. The assembly sequence is 101, 110, 106, 115, 102, 111, 107, 116, 103, 112, 108, 117, 104, 113, 109, 118, 105, 114. By first performing cross positioning and then X-shaped positioning, the stability of the bolt connection and the flatness of the connection are improved. The brake disc rotation positioning device 5 facilitates the orderly execution in sequence. According to the above sequence, a pre-tightening of 20 Nm is performed first, followed by a pre-tightening of 40 Nm, and finally a final tightening of 80 Nm is completed to achieve the best tightening effect.

[0052] In summary, the advantages of this invention are that it enables the automatic assembly of bolts 7, nuts 8 and sleeves 9 on the locomotive brake disc, improves overall assembly efficiency, saves time and labor, prevents errors and laziness during manual assembly, ensures assembly consistency, and further ensures the assembly quality of the locomotive brake disc.

[0053] While the disclosure is as stated above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this invention.
