Abstract

This invention provides a rim processing device and manufacturing equipment for a reverse disc brake wheel hub, including a mounting and positioning mechanism, a mounting base feeding mechanism, and a welding mechanism. The mounting and positioning mechanism can load and position the rim or semi-finished wheel hub body to be processed. The mounting base feeding mechanism can place the mounting post for mounting the reverse disc brake disc onto the rim for welding. The welding mechanism can weld the mounting base to the rim. Using this processing device, a reverse disc brake wheel hub with a mounting base and rim made of high-strength materials, such as iron, can be manufactured.

Description

[0002] Currently, reverse disc brake rims and corresponding brake systems are increasingly being used in electric vehicles and motorcycles. A reverse disc brake rim consists of the rim body and a reverse disc brake disc mounted on one side. The reverse disc brake disc has a larger diameter, and the corresponding brake system includes a caliper to clamp the disc and a hydraulic drive mechanism. Compared to traditional disc brake rims and corresponding brake systems, reverse disc brake rims and corresponding brake systems offer better braking performance. However, currently available reverse disc brake rims are typically made of a single piece of aluminum alloy, including the mounting posts for the brake disc. Due to the limited strength of aluminum alloy, using such reverse disc brake rims carries a risk of the mounting posts cracking or even breaking under heavy loads or during sudden braking downhill, compromising driving safety.

Detailed Implementation

[0035] To make the technical means, creative features, objectives and effects of the present invention easy to understand, the following describes in detail the rim processing device and anti-disc brake wheel hub manufacturing equipment of the present invention with reference to embodiments and accompanying drawings.

[0036] <Example>

[0037] Figure 1 This is a top view of the anti-disc brake wheel hub manufacturing equipment in this embodiment.

[0038] like Figure 1 As shown, this embodiment provides a reverse disc brake hub manufacturing equipment 1000 for manufacturing iron-aluminum composite reverse disc brake hubs. The reverse disc brake hub manufacturing equipment 1000 includes a connector feeding device 200, a spoke manufacturing device 300, a rim manufacturing device 400, a welding device 500, and a rim processing device 600 for reverse disc brake hubs.

[0039] To better explain the function of each device, the structure of the iron-aluminum composite anti-disc brake hub will be explained first below.

[0040] Figure 2 This is a perspective view of the iron-aluminum composite anti-disc brake hub in this embodiment.

[0041] like Figure 2 As shown, the anti-disc brake hub 100 includes an anti-disc brake hub body 110, an anti-disc brake disc 120 mounted on one side of the anti-disc brake hub body 110, and a plurality of fasteners 130 for mounting the anti-disc brake disc 120.

[0042] Figure 3 This is a perspective view of the main body of the anti-disc brake wheel hub in this embodiment. Figure 4 This is a cross-sectional view of the main body of the anti-disc brake wheel hub in this embodiment.

[0043] like Figure 3 and Figure 4 As shown, the anti-disc brake hub body 110 includes a rim 111, spokes 112, multiple connectors 113, and multiple mounting bases 114.

[0044] Figure 5 This is a cross-sectional view of the wheel rim in this embodiment.

[0045] like Figure 5 As shown, the rim 111 is made of iron and has a groove bottom 1111, a bead seat 1112 and a rim 1113, which is a conventional structure and will not be described in detail.

[0046] The spokes 112 are made of aluminum alloy and are formed by die casting of molten aluminum alloy. The spokes 112 include an integrally formed spoke body 1121 and multiple spokes 1122.

[0047] Because iron and aluminum alloys have different melting points, the iron rim 111 and the aluminum alloy spokes 112 cannot be effectively welded. Therefore, a connector 113 is provided to connect the two. The connector 113 is a sheet-like piece with an L-shaped or U-shaped cross-section, made of a material that can be effectively welded to the iron rim 111, such as iron. A portion of the connector 113 is pre-embedded at the outer end of each spoke during the casting of the spokes 112, and another portion of the connector 113 protrudes from the spoke ends for welding to the inner ring of the rim 111.

[0048] Figure 5 This is a perspective view of the mounting base in this embodiment. Figure 6 These are perspective views of the mounting base at different angles in this embodiment, provided for ease of description. Figure 5 The x, y, and z axes are marked in the figure. In this embodiment, the x-axis is taken as the length direction of the mounting base, the y-axis as the width direction of the mounting base, and the z-axis as the height direction of the mounting base.

[0049] like Figure 5 and Figure 6 As shown, the mounting base 114 is made of iron and has a mounting portion 1141, a mating portion 1142, and a limiting portion 1143. The mounting base 114 is generally shaped like a chamfered column, and its cross-section along the radial direction of the rim 111 is "pistol-shaped". The length direction of each mounting base 114 is the axial direction of the rim 111.

[0050] The mounting portion 1141 is used to mount the reverse disc brake disc 120. The mounting portion 1141 is cylindrical, and its cross-sectional shape along its length can be considered as consisting of a taller trapezoid and a shorter trapezoid, with their short sides meeting at an arc-shaped junction. A mounting hole 114a is provided at one end of the mounting portion 1141 along its length. In this embodiment, the mounting hole 114a is a threaded hole, and the centerline of the threaded hole is also axially aligned with the rim 111. Alternatively, a metal part with a threaded hole can be directly purchased and machined into the mounting base 114, or a metal part without a threaded hole can be used to first machine the outline of the mounting base 114, and then the threaded hole can be machined by tapping. In this embodiment, a mounting base 114 with a threaded hole is used as an example for explanation.

[0051] The mating portion 1142 is used to mate with the rim 111. The mating portion 1142 extends from the other end of the mounting portion 1141 along its length, and its extension direction is also consistent with the length direction of the mounting portion 1141. One end of the mating portion 1142 in the height direction has the same shape as the mounting portion 1141, and the other end in the height direction has a notch 1142a, so that the mating portion 1142 has a mating surface 421 for mates with the rim 111.

[0052] The mating surface 421 includes a first abutting surface 4211 and a second abutting surface 4212. The first abutting surface 4211 abuts against the groove bottom 1111 and has a shape that matches the sidewall of the groove bottom 1111, being approximately an arc-shaped surface. The second abutting surface 4212 abuts against the rim 1113 and the bead seat 1112 and has a matching shape. The second abutting surface 4212 is a relatively complex curved surface, which can be roughly considered as containing two arc-shaped surfaces. A step 1142b is formed between the two arc-shaped surfaces (i.e., at the junction of the rim 1113 and the bead seat 1112).

[0053] The mating surface 421 has four edges, namely, the first edge 421a to the fourth edge 421d. The first edge 421a contacts the bottom of the groove bottom 1111 in the circumferential direction of the rim 111, and is arc-shaped, its curvature matching the circumferential curvature of the outer wall of the groove bottom 1111 near the bottom. The second edge 421b contacts the outer end of the rim 1113 in the circumferential direction of the rim 1111, and is arc-shaped, its curvature matching the circumferential curvature of the outer end of the rim 1113. The two ends of the third edge 421c are connected to one end of the first edge 421a and one end of the second edge 421b, respectively. The third edge 421c contacts and approximately fits the rim 1113 and the bead seat 1112, and is curved, its shape matching the shape of the inner ring of the rim 111 from the bead seat 1112 to the rim 1113. The two ends of the fourth edge 421d are connected to the other ends of the first edge 421a and the second edge 421b, respectively, and the shape of the fourth edge 421d is consistent with that of the third edge 421c.

[0054] The welded portion (which can be a weld point or a welding rod) between the mounting base 114 and the rim 111 is provided between at least one of the first edge 421a to the fourth edge 421d and the rim 111. Welding can be performed using any one of laser welding, argon arc welding, or carbon dioxide shielded welding. Preferably, laser welding is used.

[0055] The limiting portion 1143 extends from the edge of the mounting portion 1141 at one end with the mounting hole 114a, and its extending direction is consistent with the length direction of the mounting portion 1141. The limiting portion 1142 is in the shape of an arc plate, the curvature of which matches the curvature of the edge of the reverse disc brake disc 120, and its extending length is slightly greater than the overall thickness of the reverse disc brake disc 120, and is used to limit the reverse disc brake disc 120.

[0056] For ease of description, the two end faces in the height direction of the mounting base 114 are referred to as the first end face 1144 and the second end face 1145, respectively, wherein the second edge 421b of the mating surface 421 is connected to one edge of the second end face 1145.

[0057] Figure 7 yes Figure 4 A magnified view of the area inside circle C. Figure 8 This is a side view of the mounting base in this embodiment.

[0058] like Figure 7 and Figure 8 As shown, in the axial direction of the anti-disc brake hub 100, the mounting portion 1141 of the mounting base 114 extends beyond the rim 1113 of the rim 111. The anti-disc brake disc 120 can be mounted on the outside of one side of the hub body 110 through the mounting base 114. In this way, an anti-disc brake disc 120 with a diameter close to that of the hub body 110 can be used, and a certain gap is provided between the anti-disc brake disc 120 and the rim 1113 of the rim 111 to provide sufficient space for installing the caliper.

[0059] In the axial direction of the disc brake hub 100, the length l1 of the notch 1142a corresponds to the total length of the bead seat 1112 and the rim 1113. Combined with the shape of the mating surface 421, this allows the mounting seat 114 to fit snugly against the inner ring of the rim 111. In the radial direction of the disc brake hub 100, the height h of the mounting seat 114 is less than the distance D3 from the middle of the groove bottom 1111 to the farthest end of the rim 1113. Furthermore, in the radial direction of the disc brake hub 100, the distance d1 from the step 1142b of the mounting seat 114 to the second end face 1145 is less than the height D1 of the rim 1113 (i.e., the distance from the second bend to the edge of the rim 112), and the distance d2 from the step 1142b to the first end face 1144 is less than the distance D2 from the end of the rim extension 1112 near the rim 1113 (i.e., the second bend) to the middle of the groove bottom 1111.

[0060] In this way, in the radial direction of the anti-disc brake hub 100, the mounting seat 114 is located between the outer end of the rim 1113 and the bottom surface of the groove 1111. That is, the first end face 1144 of the mounting seat 114 does not exceed the edge of the rim 111, so it will not affect the installation of the tire. The second end face 1145 of the mounting seat 114 does not exceed the middle of the inner ring of the rim 111, so the mounting seat 114 is not visible from the other side of the anti-disc brake hub 100, making the wheel look more aesthetically pleasing. Furthermore, the mounting seat 114 does not obstruct the connector 113 from either direction, so it will not affect the welding of the connector 113. In terms of process, the mounting seat 114 can be welded to the rim 111 first, and then the spokes 112 can be welded to the rim 111 through multiple connectors 113, or the spokes 112 can be connected first, and then the mounting seat 114 can be welded, which provides greater process flexibility.

[0061] like Figure 2 As shown, the diameter of the anti-disc brake disc 120 is close to the diameter of the wheel hub, and it includes an integrally formed brake part 121 and a mounting disc part 122.

[0062] The brake part 121 is in the shape of a circular plate and has multiple circular through-holes 121a to ensure air circulation and reduce the heat loss of the brake part 121.

[0063] The mounting disc portion 122 extends outward from the outer edge of the brake portion 121. The mounting disc portion 122 is annular in shape, and its outer edge is gear-shaped, having multiple outwardly protruding portions 1221. Each of these protruding portions 1221 has mounting holes 1221a, which are evenly distributed along the circumference of the mounting disc portion 122. Other protruding portions 1221 have strip-shaped holes. In this embodiment, the reverse disc brake disc 120 has six circular through mounting holes 1221a evenly distributed along its circumference. The distribution of five mounting holes 1221a corresponds to the distribution of five threaded holes 114a.

[0064] In addition, a circular heat dissipation groove 120a is provided between the brake part 121 and the mounting disc part 122 for heat dissipation during braking and for expelling debris generated by friction between the brake caliper and the anti-disc brake disc 120.

[0065] Based on the structure of the above-described anti-disc brake hub 100, the various devices used to manufacture the anti-disc brake hub will be described in detail below.

[0066] The connector feeding device 200 supplies the required number of connectors 113 to the spoke manufacturing device 220 for manufacturing one anti-disc brake hub 100, thereby enabling the spoke manufacturing device 220 to manufacture spokes 112 pre-embedded with connectors 113. Specifically, the connector feeding device 200 includes a vibratory feeder and a feed channel for arranging and sequentially outputting multiple disordered connectors 113, a positioning plate for positioning multiple connectors 113, a first robotic arm for gripping connectors 113 from the output end of the feed channel and placing them onto the positioning plate, and a second robotic arm for simultaneously gripping and placing multiple connectors 113 arranged on the positioning plate into the die-casting machine to open the mold. The connector feeding device 200 may specifically adopt a structure found in the prior art.

[0067] The spoke manufacturing apparatus 300 is used to cast molten aluminum into aluminum alloy spokes 112. Specifically, the spoke manufacturing apparatus 300 includes an aluminum molten aluminum holding machine for keeping the molten aluminum moist, an aluminum molten aluminum transfer mechanism for injecting the molten aluminum into a die-casting machine, a die-casting machine and mold for casting aluminum alloy spokes, and a robotic arm for removing the spokes from the open mold after die-casting. The spoke manufacturing apparatus 300 may specifically adopt a structure from the prior art.

[0068] The rim manufacturing apparatus 400 is used to form a rim 111 from steel strip. Specifically, the rim manufacturing apparatus 400 includes a cutting machine for cutting the steel strip, a coiling machine for coiling and welding the cut steel strip pieces, an expanding machine for expanding the steel strip coil, a shaping machine for processing the expanded steel strip coil into a concave-convex structure for mounting a tire, and a machine for punching valve core holes on the rim, etc. The rim manufacturing apparatus 400 may specifically adopt a structure from the prior art.

[0069] The welding device 500 is used to weld the connecting parts at the ends of the rim 111 and the spokes 112 to form a semi-finished wheel hub body. Specifically, the welding device 500 is a multi-station press-fit welding machine, used to press the spokes 112 into the inner ring of the rim 111, and to weld the connecting parts 113 at the outer ends of each spoke 1122 of the spokes 112 to the inner ring of the rim 111, thereby forming a semi-finished wheel hub body.

[0070] The rim processing device 600 for anti-disc brake hubs is used to place and weld multiple mounting seats 114 onto the rim 111, thereby forming the anti-disc brake hub body 110. The rim processing device 600 for anti-disc brake hubs can process the semi-finished hub body or process the individual rim 111. The following will be explained in detail using the semi-finished hub body as an example.

[0072] like Figures 9 to 11 As shown, the rim processing device 600 for anti-disc brake hubs (hereinafter referred to as rim processing device 600) includes a frame 610, a mounting and positioning mechanism 620, a mounting base feeding mechanism 630, a welding mechanism 640, and a processing control mechanism 650.

[0073] The frame 610 consists of a frame and multiple cover plates mounted on the frame, and is in the shape of a cuboid. The upper cover plate 611 on the upper surface has multiple mounting holes for installation.

[0074] The placement and positioning mechanism 620 is used to place the aforementioned semi-finished wheel hub body or wheel rim 111 and to position it during processing. This embodiment uses the semi-finished wheel hub body as an example. The placement and positioning mechanism 620 includes a protective component 621, a placement seat 622, a lifting drive component 623, a rotation drive component 624, and a centering component 625.

[0075] The protective assembly 621 protects the mounting base 622 and lifting drive assembly 623 below it during welding. The protective assembly 621 includes a protective plate 6211 and multiple support pillars 6212, which are respectively mounted on the upper cover plate 611. The four corners of the protective plate 6211 are connected to the upper ends of each support pillar 6212. The protective plate 6211 has a circular through-hole 6211a in the center, the diameter of which is larger than the diameter of the rim 111.

[0076] The mounting base 622 is used to hold the semi-finished wheel hub body to be processed. The mounting base 622 is disc-shaped, and its diameter is slightly larger than the outer diameter of the semi-finished wheel hub body. Its upper end surface is a horizontal surface for placing the semi-finished wheel hub body.

[0077] The lifting drive assembly 623 is used to drive the carrier 622 to rise and fall. It includes three lifting rods 6231 and three lifting cylinders (not shown in the figure). The three lifting rods 6231 are respectively inserted into three through holes in the upper cover plate 611, and the upper end face of the lifting rod 6231 abuts against the bottom surface of the carrier 622. The three lifting cylinders are disposed in the frame 610 and are used to drive the three lifting rods 6231 to rise and fall, thereby driving the carrier 622 and the semi-finished wheel hub body on it to rise and fall.

[0078] The rotary drive assembly 624 is used to drive the mounting base 622 to rotate horizontally. It includes a bottom connector 6241, a rotary connecting rod, and a rotary drive motor (not shown in the figure). The bottom connector 6241 is block-shaped and is installed in the middle of the bottom surface of the mounting base 622.

[0079] The centering assembly 625 cooperates with the mounting base 622 and the lifting drive assembly 623 to fix and center the semi-finished wheel hub body to be processed. The centering assembly 625 includes an L-shaped bracket mounted on the upper cover plate 611, a connecting rod mounted on the end of the L-shaped bracket and extending vertically downward, and a centering pressure fitting 6251 mounted on the lower end of the connecting rod. The lower end of the centering pressure fitting 6251 is conical, and the rest is cylindrical, with the diameter of the cylinder being larger than the diameter of the central hole on the semi-finished wheel hub body. The central axis of the centering pressure fitting 6251 is substantially collinear with the central axis of the mounting base 622 and the rotating connecting rod.

[0080] When the mounting base 622 is raised, the conical end of the centering pressure fitting 6251 abuts against one edge of the center hole of the semi-finished wheel hub body, thereby pressing the semi-finished wheel hub body onto the mounting base 622 and making the central axis of the semi-finished wheel hub body collinear with the central axis during rotation.

[0081] The mounting base feeding mechanism 630 includes a vibratory feeder 631, a guide assembly 632, a feed channel 633, a pusher assembly 634, a pusher drive assembly 635, a pick-up assembly 636, and a pick-up drive assembly 637.

[0082] The vibratory feeder 631 arranges the multiple mounting seats 114 contained therein by vibration and outputs the mounting seats 114 sequentially to the material channel 633. The vibratory feeder 631 has a spiral material channel inside. Under its vibration, the mounting seats 114 will be arranged along the spiral material channel and move towards the upper outlet of the spiral material channel.

[0083] The guide assembly 632 is located at the outlet of the spiral channel of the vibratory feeder 631 and is used to guide the correctly oriented mounting seat 114 to the channel 233 and cause the incorrectly oriented mounting seat 114 to fall back into the vibratory feeder 631.

[0084] Figure 12 This is an enlarged view of part of the mounting base feeding mechanism in this embodiment. Figure 1 .

[0085] like Figure 12As shown, the guide assembly 632 includes an arc-shaped guide plate 6321. One end of the guide plate 6321 is connected to the outlet of the spiral feed channel, and the other end is connected to the inlet of the feed channel 633. The lower end of the guide plate 6321 is located on the upper surface of the edge of the vibratory feeder 631. The guide plate 6321 has an inclined end face 6321a facing into the vibratory feeder 631. Multiple parallel guide grooves are provided in the middle of the inclined end face 6321a. Each guide groove is a narrow V-shaped groove extending from one end of the inclined end face 6321a along its length to the other end. Furthermore, from the end connected to the spiral feed channel to the end connected to the feed channel 633, the radius of curvature of the guide plate 6321 gradually increases, causing the lower end of the guide plate 6321 to divide the upper surface of the vibratory feeder 631 into a support end face 632a. The support end face 632a is approximately horizontal, and its width gradually increases from the end closest to the spiral feed channel to the other end.

[0086] The end of the mounting base 114 with the threaded hole is designated as the large end, and the other end as the small end. In this embodiment, at the guide plate 6321, the mounting base 114 with the large end facing upwards and the mating portion 1142 facing the guide plate 6321 is the correctly oriented mounting base 114. The mounting base 114 rises spirally along the spiral channel within the vibratory feeder 631. Laterally oriented mounting bases 114 will lose balance and fall back into the vibratory feeder 631 because their center of gravity is outside the spiral channel. Vertically oriented mounting bases 114 with the large end facing downwards will also fall back into the vibratory feeder 631 because the width of the end of the supporting end face 632a closest to the spiral channel is very small. Vertically oriented mounting bases 114 with the mating portion 1142 facing inwards towards the vibratory feeder 631 will also fall back into the vibratory feeder 631 because their center of gravity is outside the supporting end face 632a due to the tilt angle of the guide plate 6321. In this way, only the correctly oriented mounting base 114 (i.e., with the larger end facing upwards and the mating part 1142 facing the guide plate 6321) will pass through the guide plate 6321 and be conveyed onto the feed channel 633, meaning that all mounting bases 114 on the feed channel 633 have the same orientation. Furthermore, when the correctly oriented mounting base 114 passes through the guide plate 6321, its second edge 421b will embed into one of the guide grooves 421b, allowing the mounting base 114 to pass through the guide plate 6321 more smoothly and preventing the correctly oriented mounting base 114 from falling back into the vibratory feeder 631 due to friction. The multiple parallel guide grooves 421b allow the device to be used with mounting bases 114 of various sizes and specifications.

[0087] The cross-section of the feed channel 633 is rectangular, with its width slightly greater than the thickness of the mounting base 114 and its height at least greater than the length of the mating portion 1142 of the mounting base 114. In this way, the mounting base 114 can be clamped between the two side walls of the feed channel 633.

[0088] The pusher assembly 634 is used to push a mounting base 114 at the outlet of the material channel 633 to a predetermined position so that the picking assembly 636 can pick up the mounting base 114.

[0089] Figure 13 This is an enlarged view of part of the mounting base feeding mechanism in this embodiment. Figure 2 .

[0090] like Figure 13 As shown, the material pushing assembly 634 includes a material pushing bracket 6341, two auxiliary positioning plates 6342, and a material pushing plate 6343.

[0091] The pusher bracket 6341 is an I-shaped component, installed on the upper cover plate 611, and the upper end face of the pusher bracket 6341 is horizontal.

[0092] Two auxiliary positioning plates 6342 are installed parallel to each other on the upper surface of the pusher bracket 6341, and their spacing is adapted to the width of the mounting base 114.

[0093] Each auxiliary positioning plate 6342 has a clamping notch 6342a. The clamping notch 6342a is a rectangular notch with its opening facing upwards. Its length is vertical, and its width matches the thickness of the mounting base 114. The clamping notch 6342a extends through the thickness of the auxiliary positioning plate 6342. The two clamping notches 6342a on the two auxiliary positioning plates 6342 are aligned along their arrangement direction.

[0094] One of the auxiliary positioning plates 6342 is shorter in length, and one end of the auxiliary positioning plate 6342 (the end away from the clamping notch 6342a) abuts against the outer wall of the material channel 633. Along the length of the material channel 633, one end of the other auxiliary positioning plate 6342 is located directly in front of the outlet of the material channel 633.

[0095] The pusher plate 6343 includes an integrally formed cuboid-shaped pusher limiting part 63431 and a rectangular plate-shaped pusher plate part 63432. One end of the pusher plate part 63432 in the longitudinal direction is connected to the middle of one end of the pusher limiting part 63431 in the longitudinal direction. The thickness of the pusher plate part 63432 is adapted to the distance between the two auxiliary positioning plates 6342, and it can extend between the two auxiliary positioning plates 6342. A receiving notch 6343a is provided on the end of the pusher plate part 63432 in the longitudinal direction away from the pusher limiting part 63431. The receiving notch 6343a is also an upward-facing rectangular notch that extends along the thickness direction of the pusher plate part 63432, and its width is adapted to the thickness of the mounting base 114. When one end of the pusher limiting part 63431 in the length direction abuts against the two auxiliary positioning plates 6342, the receiving notch 6343a and the two clamping notches 6342a are aligned in the arrangement direction of the two auxiliary positioning plates 6342.

[0096] The pusher drive assembly 635 includes a guide rail 6351, a slider 6352, and a pusher cylinder 6353.

[0097] The guide rail 6351 is mounted on the pusher bracket 6341, and its extension direction is consistent with the length direction of the auxiliary positioning plate 6342. The slider 6352 is slidably fitted onto the guide rail 6351. The pusher limiting part 63431 of the pusher plate 6343 is fixedly mounted on the slider 6352. The pusher cylinder 6353 is used to drive the pusher plate 6343 to move along the guide rail 6351.

[0098] The material handling assembly 636 includes a pair of material handling jaws 6361 for gripping a mounting base 114 from the gripping notch 6342a of the auxiliary positioning plate 6342. The material handling jaws 6361 are L-shaped and have a certain degree of elasticity. The ends of the jaws used to grip the mounting base 114 have concave arc-shaped end faces, and the pair of arc-shaped end faces of the pair of material handling jaws 6361 face each other.

[0099] The material handling drive assembly 637 includes a gripper drive cylinder 6371, a horizontal electric slide 6372, a vertical guide rail 6373, and a vertical drive cylinder 6374.

[0100] The gripper drive cylinder 6371 is used to drive a pair of grippers 6361 to move closer or further apart, thereby gripping or releasing the mounting base 114.

[0101] A horizontal electric slide table 6372 is horizontally positioned, and a vertical drive cylinder 6374 is mounted on the slider of the horizontal electric slide table 6372, with its output end extending and retracting in the vertical direction. A gripper drive cylinder 6371 is mounted on the output end of the vertical drive cylinder 6374 via a connecting plate, and the connecting plate is slidably engaged with the vertical guide rail 6373.

[0102] Therefore, the vibratory feeder 631 outputs a mounting seat 114 to the feed channel 633 through vibration, pushing multiple mounting seats 114 on the feed channel 633 toward the material receiving assembly 636. One mounting seat 114 at the outlet of the feed channel 633 is pushed into the receiving notch 6343a on the pusher plate 6343 aligned with the feed channel 633. Then, driven by the pusher drive assembly 635, the pusher plate 6343 moves horizontally until its pusher limiting part 63431 abuts against the two auxiliary positioning plates 6342. The material handling drive assembly 637 drives a pair of material handling jaws 6361 to move to both sides of the two gripping notches 6342a, and drives the pair of material handling jaws 6361 to move closer to each other, pass through the gripping notches 6342a to clamp the mounting seat 114 in the receiving notch 6343a, and then drives the material handling jaws 6361 to place the mounting seat 114 on the rim 111 on the carrier 622, and maintains the clamping of the mounting seat 114.

[0103] In this embodiment, the bottom of the receiving notch 6343a on the pusher plate 6343 and the side of the groove bottom 1111 (the upper side) of the wheel rim 111 on the raised mounting seat 622 are basically the same in the vertical direction. Therefore, by moving the vertical drive cylinder 6374 by the same stroke in the vertical direction, a mounting seat 114 can be accurately placed on the wheel rim 111 and pressed tightly.

[0104] The welding mechanism 640 includes two welding torch supports 641, two welding torches 642, and a welding torch drive unit 643. In this embodiment, the welding torch drive unit 643 is an electric slide table.

[0105] The welding torch holder 641 includes multiple support rods 6411, multiple sets of clamping members 6412, and welding torch grippers. The ends of two support rods 6411 are mounted on a set of clamping members 6412. One end of one support rod 6411 at one end of the entire welding torch holder 641 is fixedly mounted on the slider of an electric slide table, and one end of another support rod 6411 at the other end of the welding torch holder 641 is provided with a welding torch gripper, on which the welding torch 642 is clamped. In this way, the welding torch 642 is fixed at a certain tilt angle and can move along the length of the electric slide table under its drive. In this embodiment, the two welding torches 642 have different tilt angles and are mounted on the same electric slide table via two welding torch holders 641. The two welding torches 642 are used to weld the first edge 421a and the second edge 421b of the mounting base 114, respectively.

[0106] In this embodiment, welding torch 642 is a laser welding torch.

[0107] It should be noted that, since the lengths of the first edge 421a and the second edge 421b are relatively small, and laser welding allows for a certain margin, the first edge 421a and the second edge 421b should have a certain curvature, but straight-line welding can achieve the desired welding effect.

[0108] In addition, the rim processing device 600 for anti-disc brake hubs also includes multiple detection components. In this embodiment, the detection components include a feed sensor and a take-up sensor (not shown in the figure).

[0109] The feeding sensor is located next to the pusher plate 6343 with its detection end facing the outlet of the material channel 633. When the pusher plate 6343 is in the retracted state, the feeding sensor can sense the process of the material receiving notch 6343a of the pusher plate 6343 from being empty to receiving a mounting base 114 (for example, sensing the change in light caused by the mounting base 114 being placed into the notch), and generate a corresponding feeding signal.

[0110] The material pick-up sensor is located next to the auxiliary positioning plate 6342 with its detection end facing the position between the two pick-up notches 6342a. When the pusher plate 6343 is in the push-out state, the material pick-up sensor can sense the process of one of the mounting seats 114 being taken away from the material receiving notch 6343a of the pusher plate 6343, and generate a corresponding material pick-up signal.

[0111] The feeding sensor and the picking sensor can be photoelectric sensors, proximity sensors, etc., as used in existing technologies.

[0112] Figure 14 This is a block diagram of the processing control mechanism in this embodiment.

[0113] like Figure 14 As shown, the processing control mechanism 650 includes a detection signal acquisition unit 6501, an input display unit 6502, a lifting control unit 6503, a vibration control unit 6504, a pusher plate reset control unit 6505, a pusher control unit 6506, a clamping control unit 6507, a welding control unit 6508, a rotation control unit 6509, and a main control unit 6510.

[0114] The detection signal acquisition unit 6501 is used to acquire the detection signals generated by the detection component, including the aforementioned material supply arrival signal and material pick-up signal.

[0115] The input display unit 6502 is used to display status information to the user and allow the user to operate it. The user can confirm through the input display unit 6502 that the semi-finished anti-disc brake wheel hub to be processed has been placed on the mounting base 622 and start processing.

[0116] When the user starts processing through the input display unit 652, the lifting control unit 6503 controls the lifting drive assembly 623 to drive the carrier 622 to rise. After the carrier 622 is raised, the anti-disc brake wheel hub semi-finished product on it is clamped and fixed by the carrier 622 and the centering pressure component 6251, and is centered by the centering pressure component 6251.

[0117] When the detection signal acquisition unit 6501 receives the material pick-up signal, the vibration control unit 6504 controls the vibratory feeder 631 to start and continue for a predetermined time to output a mounting base 114.

[0118] When the detection signal acquisition unit 6501 receives the material pick-up signal, the pusher plate reset control unit 6505 controls the pusher cylinder 6353 to drive the pusher plate 6343 to move, so that it retracts to the position of the material receiving notch 6343a in front of the material channel 633 outlet, so as to pick up the next mounting seat 114.

[0119] When the user starts processing or when the detection signal acquisition unit 651 receives the material release signal, the material pushing control unit 6506 controls the material pushing cylinder 6353 to drive the material pushing plate 6343 to move, so that it extends until the receiving notch 6343a is aligned with the two clamping notches 6342a, so that the material picking component 636 can pick it up.

[0120] After the material pushing control unit 654 controls the material pushing cylinder 6353 to drive the material pushing plate 6343 to extend, the clamping control unit 6507 controls the horizontal electric slide 6372 and the vertical drive cylinder 6374 to move a pair of material picking claws 6361 to the clamping notch 6342a. Then, it controls the claw drive cylinder 6371 to drive the pair of material picking claws 6361 to move closer together and clamp a mounting seat 114. Then, it controls the horizontal electric slide 6372 and the vertical drive cylinder 6374 to move the pair of material picking claws 6361 and the clamped mounting seat 114 to the rim 111 of the semi-finished wheel hub body on the raised carrier 622. In this embodiment, the clamping control unit 6507 places the mounting seat 114 in the same position each time. With rotation, multiple mounting seats 114 can be set on the rim in sequence.

[0121] After the clamping control unit 6507 places the mounting base 114 onto the rim 111, the welding control unit 6508 simultaneously controls the two welding torches 642 to start welding and continue for a predetermined time, and controls the electric slide to drive the two welding torch supports 641 and the two welding torches 642 to move horizontally, thereby simultaneously completing the welding of the first edge 421a and the second edge 421b of the mounting base 114.

[0122] After the welding control unit 6508 completes a welding operation, the clamping control unit 6507 controls the jaw drive cylinder 6371 to drive a pair of material-picking jaws 6361 to release, and controls the horizontal electric slide 6372 and the vertical drive cylinder 6374 to drive the pair of material-picking jaws 6361 to reset.

[0123] After the welding control unit 6508 completes one welding operation, the rotation control unit 6509 controls the rotation drive motor to drive the mounting base 622 to rotate in one direction by a predetermined angle. The predetermined angle corresponds to the number of mounting bases 114. In this embodiment, there are six mounting bases 114, so the predetermined angle is 60°.

[0124] After the welding is completed under the control of the welding control unit 658, the lifting control unit 6503 controls the carrier 622 to descend so as to remove the processed anti-disc brake wheel hub body.

[0125] The main control unit 6510 controls the operation of the above-mentioned functional units, including starting a count after the user starts processing through the input display unit 6502, incrementing the count by one when a welding is completed by the welding control unit 6508, and sending a corresponding processing completion signal to the lifting control unit 6503 and the clamping control unit 6507 when the count reaches the number of mounting seats 114 required for one anti-disc brake wheel hub. The lifting control unit 6503 controls the mounting seat 622 to descend so as to remove the processed anti-disc brake wheel hub body; the clamping control unit 6507 stops clamping.

[0126] Figure 15 This is a flowchart of the manufacturing process for the anti-disc brake wheel hub in this embodiment.

[0127] like Figure 15 As shown, the manufacturing process for anti-disc brake wheels includes:

[0128] Step S1: The connecting component feeding device 200 is used to feed materials to the spoke manufacturing device 300, that is, multiple connecting components are arranged and placed in the corresponding positions in the mold of the die-casting machine.

[0129] Step S2: Use the spoke manufacturing device 300 to manufacture spokes with pre-embedded connectors;

[0130] Step S3: Use the rim manufacturing device 400 to manufacture the rim.

[0131] Step S4: Use welding device 500 to press fit the spokes and rim, and weld the connecting parts at the ends of the spokes to the rim to obtain the semi-finished wheel hub body.

[0132] Step S5: Using the rim processing device 600 for anti-disc brake wheel hubs, multiple mounting seats 114 are welded to the rim of the semi-finished wheel hub body to obtain the anti-disc brake wheel hub body.

[0133] Step S6: Install the anti-disc brake disc onto multiple mounting seats 114 on the anti-disc brake hub body to obtain the anti-disc brake hub.

[0134] Figure 16 This is a flowchart of the rim processing for the anti-disc brake wheel hub in this embodiment.

[0135] like Figure 16 As shown, based on the aforementioned rim processing device 600 for anti-disc brake hubs, the specific process for processing the rim of the anti-disc brake hub after the user starts processing includes the following steps:

[0136] Step S5-1, the main control unit 6510 sets the counter i = 0.

[0137] In step S5-2, the lifting control unit 6503 controls the carrier 622 to rise, and a semi-finished wheel hub body on the carrier 622 is fixed and centered.

[0138] In step S5-3, the pusher control unit 6506 controls the pusher plate 6343 to extend and move one of the mounting seats 114 in its receiving notch 6343a to the clamping notch 6342a.

[0139] In step S5-4, the clamping control unit 6507 controls a pair of clamping jaws 6361 to clamp a mounting base 114 from the clamping notch 6342a and place the mounting base 114 on the edge of the rim 111 on the carrier 622. At this time, the material sensor generates a material-taken signal.

[0140] In step S5-5, upon receiving the material pick-up signal, the pusher plate reset control unit 6505 controls the pusher plate 6343 to reset. At this time, the material receiving notch 6343a is located directly in front of the material channel 633 outlet.

[0141] In steps S5-6, upon receiving the material pick-up signal, the vibration control unit 6504 controls the vibratory feeder 631 to vibrate and outputs a mounting seat 114. The mounting seat 114 is output onto the material channel 633, pushing the front mounting seats 114, with the foremost mounting seat 114 being pushed into the receiving notch 6343a of the pusher plate 6343. At this time, the feeding sensor generates a feeding completion signal.

[0142] In step S5-7, the welding control unit 6508 controls two welding torches 642 to simultaneously weld the first edge 421a and the second edge 421b of the mounting base 114.

[0143] In step S5-8, the rotation control unit 6509 controls the mounting base 622 to rotate by a predetermined angle.

[0144] In step S5-9, the main control unit 6510 sets i = i+1.

[0145] In step S5-10, the main control unit 6510 determines whether there is i = N, where N is the total number of mounting seats 114 in a predetermined hub, i.e., whether all mounting seats 114 have been installed. If the determination is negative, the system returns to step S5-4 and continues to clamp the next mounting seat 114 and perform welding and rotation.

[0146] In step S5-11, when the determination in step S5-10 is yes, the main control unit 6510 sends a corresponding signal to the lifting control unit 6503, and the lifting control unit 6503 controls the carrier 622 to descend, at which point the processed anti-disc brake wheel hub body can be taken out.

[0147] By following the steps above, the rim processing of the anti-disc brake wheel hub can be completed automatically.

[0148] Functions and effects of the embodiments

[0149] The rim processing apparatus and manufacturing equipment for anti-disc brake hubs provided in this embodiment include a placement and positioning mechanism, a mounting base feeding mechanism, and a welding mechanism. Because it has a placement and positioning mechanism, it can place and position the rim or semi-finished hub body to be processed. Because it has a mounting base feeding mechanism, it can place the mounting post for mounting the anti-disc brake disc onto the rim for welding. Because it has a welding mechanism, it can weld the mounting base onto the rim. Using such a processing apparatus, anti-disc brake hubs with mounting bases and rims made of high-strength materials can be manufactured. For example, both the mounting base and the rim can be made of iron, allowing the anti-disc brake hub to withstand higher shear forces. Even under heavy loads or during emergency braking downhill, it is less prone to damage, ensuring driving safety.

[0150] In this embodiment, the mounting base feeding mechanism includes a vibratory feeder, a feed channel, a pushing component, a picking component, and a corresponding driving component. The picking component consists of a pair of grippers, which can arrange multiple mounting bases sequentially through vibration and push one mounting base to a predetermined position for the picking component to grip. The picking component can then grip a mounting base and place it on the wheel rim for welding. This allows for automatic feeding of the welding material, eliminating the need for manual placement and maintenance of the mounting bases, resulting in higher production efficiency and greater safety.

[0151] Furthermore, since the output end of the vibratory feeder is equipped with a guide plate designed according to the structural characteristics of the mounting base, the mounting bases can be guided and screened, ensuring that the mounting bases on the material channel all face the same direction. This greatly simplifies the structure and control of the material handling assembly. Specifically, based on the structural characteristics of the columnar mounting base with its large and small ends and relatively inclined mating surfaces, the guide plate forms the supporting end face and the inclined end face. This allows the horizontally oriented, large-end-down, and large-end-up mounting columns with their mating surfaces facing into the vibratory feeder to fall back into the vibratory feeder, outputting only the predetermined mounting bases. Moreover, the guide plate structure is simple and easy to maintain.

[0152] Furthermore, the feeding assembly uses two auxiliary positioning plates and one movable feeding plate. Through the cooperation of their notches, a mounting seat can be pushed and accurately positioned to the predetermined position. Through the guiding effect of the notches, a pair of grippers can stably grip the mounting seat, making it less likely to be clamped on the edge of the mounting seat, which would cause it to tilt or fall off during movement. This allows the mounting seat to be stably placed on the wheel rim, and also simplifies the control of the feeding assembly.

[0153] In this embodiment, the mounting and positioning mechanism includes a mounting base, a lifting drive assembly, a rotating drive assembly, and a centering assembly. Through the lifting of the mounting base and the cooperation of the centering assembly, the semi-finished wheel hub body to be processed can be stably pressed down, ensuring that its central axis is coaxial with the rotation axis, thereby improving processing accuracy. Since the mounting base is rotatable, multiple circumferential mounting posts can be welded by repeatedly rotating the mounting base and welding one mounting post at the same position each time, greatly simplifying the control of the material handling assembly and the welding torch.

[0154] Furthermore, in this embodiment, two welding torches are used to simultaneously weld the first and second edges of the mounting base, which improves processing efficiency. Moreover, given the small size of the first and second edges of the mounting base and the allowable margin in laser welding, using an electric sliding table for linear welding ensures ideal welding results while simplifying torch control and reducing equipment costs.

[0155] In this embodiment, based on the sensor's sensing results, the processing control mechanism controls the processing of the wheel rim, making the processing process highly automated. As long as another robotic arm is set up to pick up and place the semi-finished wheel hub body to be processed and the processed anti-disc brake wheel hub body, workers do not need to operate next to the processing device for a long time, which can reduce labor costs and avoid the bright light or spatter generated by welding from causing injury to workers nearby, thus improving production safety.

[0156] The above embodiments are merely illustrative of specific implementations of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are only for illustrating the principles of the present invention. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.

[0157] For example, in the above embodiments, the rim processing device for anti-disc brake hubs is used to process the rims of iron-aluminum composite anti-disc brake hubs. In fact, the device can also process the rims of other types of hubs, such as the rims of all-iron hubs.

[0158] In the above embodiments, the rim processing device for the anti-disc brake hub is used to process the semi-finished hub body, and to center it using a centering press fitting. Alternatively, this device can also be used to process individual rims. For example, a structure for engaging and centering the rim can be provided on a mounting base, and the rim can be engaged and fixed on the mounting base and then processed. After welding mounting posts onto the rim, the spokes are press-fitted into the rim and welded, thus forming the aforementioned anti-disc brake hub.

[0159] In the above embodiment, the electric slide table simultaneously drives two welding guns to perform linear welding on the first and second edges of the mounting base. In an alternative, a robotic arm or servo module can be used to drive the welding, which can better fit the arc shape of the first and second edges and perform a slightly arc-shaped welding.

[0160] In the above embodiment, an electric slide table simultaneously drives two welding torches to weld the first and second edges of the mounting base. Alternatively, the direction of the electric slide table can be changed, or a robotic arm or servo module can be used to drive the two welding torches to simultaneously weld the third and fourth edges of the mounting base. Alternatively, the first and second edges of the mounting base can be welded first, followed by the third and fourth edges, to ensure a more secure fit between the mounting base and the rim.

[0161] In the above embodiment, the mounting base already has threaded holes before it is welded to the rim. Alternatively, the mounting bases without threaded holes can be welded to the rim first using the processing apparatus of the embodiment, and then threaded holes can be machined on each mounting base using a tapping device or tool.

[0162] In the above embodiments, both welding guns are laser welding guns. In alternative solutions, other welding equipment in the prior art can also be used.

[0163] The rim processing device for anti-disc brake hubs can also include protective baffles to shield the welding process from light and protect nearby workers.
