Description

Technical Field

[0001] The invention relates to the technical field of rim manufacturing and processing, in particular to a rim manufacturing and processing equipment for a tubeless wheel. Background Art

[0002] The rim of a wheel is the outer edge of the wheel, which supports the tire and is connected to the vehicle's suspension system. Tubeless wheels form a seal directly between the rim and the tire, and do not require an additional inner tube. The center hole, bolt holes, weight-reducing holes, and heat-dissipating holes are usually formed on the rim of a tubeless wheel by stamping. Subsequently, the burrs and excess metal generated during the stamping process need to be removed by grinding to make the edges of the holes smoother to ensure that they will not scratch the tire or cause other safety hazards.

[0003] At present, in the process of grinding the punched holes of the wheel rim, the wheel rim is usually grinded one by one by a manual handheld angle grinder, or polished by stone washing, using stones, sand or other rough materials and the wheel rim to be placed in a rotating cylinder. During the rotation in the cylinder, these materials will rub the surface of the rim, thereby forming a natural wear effect; however, manual grinding is inefficient and requires a lot of labor costs. In order to achieve all-round grinding, the position of the wheel rim needs to be constantly adjusted, and manual adjustment or flipping is laborious; stone washing processing increases manufacturing costs. If handled improperly, stone washing may cause the rim surface to be uneven, affecting its matching accuracy with the tire, and the grinding effect is difficult to control.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] A center hole and multiple threaded holes are punched out on the middle plane of the wheel rim, and multiple shock-absorbing holes are punched out on the middle inclined surface of the wheel rim. The equipment performs double-sided grinding on the punched holes on the middle plane and the middle inclined surface on the rim to remove the burrs remaining on the hole wall after punching; the left and right sides above the processing table 13 are processing positions, and the front and back sides above the processing table 13 are waiting positions. Before processing, the four wheel rims are limited by the limiting mechanism 2, and the four wheel rims are divided into two groups with two of them facing each other.

[0035] The wheel rim located at the processing position drives the grinding mechanism 4 through the driving mechanism 3 to adapt to the surface to be processed of the wheel rim and perform the grinding operation; when one side of a group of wheel rims is polished, it is moved to the waiting position by changing the horizontal position through the supporting mechanism 1, and is flipped over in conjunction with the limiting mechanism 2. During the flipping, the other group of wheel rims located at the processing position are polished, and the operations are alternately performed to improve the continuity of the equipment operation.

[0036] Reference Figure 1 and Figure 2 The limiting mechanism 2 includes a motor 21 and a clamping assembly 22 for limiting the wheel rim processing part. The motor 21 is installed on the top wall of the processing table 15 through an inverted L-shaped part. The clamping assembly 22 includes a limiting platform 221. Four limiting platforms 221 are correspondingly distributed on the top wall of the processing table 13 and the bottom wall of the processing table 2 15. The four limiting platforms 221 are rotatably connected along the circumferential direction on the top wall of the processing table 1 13 and the bottom wall of the processing table 2 15 through a torsion spring (not shown in the figure). The top wall of the limiting platform 221 is adapted to the bottom wall of the wheel rim processing part, and the bottom wall of the output end of the motor 21 is fixed to the corresponding top wall of the limiting platform 221 on the processing table 2 15.

[0037] Reference Figure 1 , Figure 2 and Figure 5The interior of the limit platform 221 is symmetrically and slidably connected with a clamping piece 222 through a spring 1, and the outer walls of the sides where the two clamping pieces 222 are close to each other are both inclined. The clamping piece 222 is composed of an L-shaped piece slidably connected to the limit platform 221 and a trapezoidal block fixed to the top wall of the vertical section of the L-shaped piece, and the outer walls of the trapezoidal blocks of the two clamping pieces 222 that are close to each other are both inclined toward the middle of the limit platform 221; an adjusting rod 223 slides through the side wall of the limit platform 221, and an adjusting block 224 is fixedly connected to one end of the adjusting rod 223 located inside the limit platform 221, and the adjusting block 224 is connected to the inner wall of the limit platform 221 through a spring 2, and the adjusting block 224 and the outer walls close to the two clamping pieces 222 are in an adaptive inclination.

[0038] Place four wheel rims on the corresponding limit platforms 221 on the processing table 13, and the limit platforms 221 are adapted to the wheel rims. When the wheel rims are placed in the limit platforms 221 on the processing table 13, the edges push the inclined side walls of the trapezoidal blocks of the clamping members 222, and the springs connecting the L-shaped members of the clamping members 222 and the limit platforms 221 are compressed, and the clamping members 222 slide close to the inner wall of the limit platforms 221 until the wheel rims completely enter the limit platforms 221. After the spring rebounds and the clamping members 222 are reset, the trapezoidal blocks of the clamping members 222 clamp and limit the wheel rims.

[0039] The top of the output end of the hydraulic rod 14 moves downward, driving the processing table 2 15 and the limit platform 221 at the bottom of the processing table 2 15 to move downward. The limit platform 221 at the bottom of the processing table 2 15 and the limit platform 221 on the processing table 1 13 limit the wheel rim up and down, and cooperate with the clamping piece 222 to prevent the wheel rim from moving in the subsequent processing process and affecting the processing effect.

[0040] Reference Figure 2 and Figure 6 The driving mechanism 3 includes a support frame 31. The top wall of the processing table 3 16 is symmetrically provided with a slide groove 2. The slide grooves 2 of the two processing tables 3 16 are slidably connected to an inverted U-shaped support frame 31 through an electric slider 2. A motor 2 32 is installed at the vertical end of the support frame 31. The horizontal section of the support frame 31 is symmetrically fixedly connected with an arc-shaped stable slide rail 33.

[0042] Reference Figures 6 to 9A support plate 41 fixed to the output end of the motor 2 32 is slidably connected to the two upper and lower opposite stable slide rails 33, and a positioning cylinder 42 is fixedly connected to the middle of the outer wall of the side away from the two support plates 41. The grinding assembly 43 includes a spring rod 431, and a plurality of spring rods 431 are evenly installed along the circumferential direction on the side wall of the support plate 41 fixed with the positioning cylinder 42. The outer wall of the output end of the plurality of spring rods 431 away from the support plate 41 is fixedly connected to a ring-shaped grinding piece 1 432, the side wall of the positioning cylinder 42 near the grinding piece 432 is slidably connected with multiple locking pieces 433 along the circumferential direction through spring three; the multiple locking pieces 433 are fixedly connected with a protrusion 434 near the side wall of the middle part of the positioning cylinder 42, and the side walls of the multiple protrusions 434 near the middle part of the positioning cylinder 42 are inclined, and the inclined outer walls of the multiple protrusions 434 are all fitted with matching protrusions 435, and the multiple protrusions 435 are commonly fixedly connected with a sliding column 436 arranged inside the positioning cylinder 42.

[0043] Reference Figure 6 , Figures 9 and 10 The locking drive assembly 44 includes a connecting piece 441, and the outer wall of the sliding column 436 close to the support disk 41 is fixedly connected with the connecting piece 441. The connecting piece 441 is composed of a disc member fixed to the sliding column 436 and a plurality of long plate members uniformly fixed along the circumferential direction of the side wall of the disc member. The side wall of the positioning cylinder 42 is provided with a plurality of adjustment grooves 442 adapted to the long plate members of the connecting piece 441. The side wall of the connecting piece 441 close to the support disk 41 is connected to the output end of the electric push rod 443 installed in the middle of the support disk 41.

[0044] Reference Figure 6 , Fig.10 and Fig.11 A grinding component 45 is arranged on the locking drive component 44, and the grinding component 45 includes a support plate 451. The side wall of the support plate 41 on which the positioning cylinder 42 is installed is evenly fixed with support plates 451 corresponding to the long plate of the connecting member 441 along the circumferential direction. The long plate of the connecting member 441 slides through the support plate 451. A support plate 453 is fixed to the middle of the side wall of the support plate 451 away from the support plate 41. The side wall of the support plate 451 away from the support plate 41 is symmetrically installed with spring rods 452 with the support plate 453 as the center. The output ends of the spring rods 452 on the same support plate 451 are hinged with a grinding component 454.

[0045] Reference Figure 10 to Figure 11The spring rod 452 is hinged to the semicircular plate 455 fixed to the side wall of the grinding piece 454, and the side wall of the support plate 453 close to the semicircular plate 455 is symmetrically slidably connected with the locking piece 457 through the spring. The outer walls of the two locking pieces 457 on the side close to each other are inclined, and the inclined outer wall of the locking piece 457 is fitted with an arrow piece 456 with an end in a matching arrow shape. The arrow piece 456 is fixed to the side wall of the long plate of the connecting piece 441, and the corresponding support plate 453 is provided with a slot for the arrow piece 456 and the locking piece 457 to slide.

[0046] The support frame 31 is adjusted by the electric slider 2 to move toward the wheel rims on the left and right sides corresponding to the positions where the wheel rims have been limited, and the support frame 31 drives the grinding mechanism 4 to move to a suitable position.

[0047] During the movement, the grinding piece 432 gradually approaches the middle plane of the wheel rim where the hole is to be ground and punched, and the spring rod 431 adaptively contracts until it is completely fitted therewith, and the grinding piece 454 gradually approaches the middle inclined surface of the wheel rim where the hole is to be ground and punched. During the fitting process of the grinding piece 454, the spring rod 452 adaptively contracts, and the grinding piece 454 adaptively deflects around the support plate 453 until the grinding piece 454 is fitted with the middle inclined surface of the wheel rim.

[0048] When the first grinding piece 432 and the second grinding piece 454 are both in contact with the wheel rim, the output end of the electric push rod 443 pushes the connecting piece 441 to move on the adjusting groove 442 .

[0049] The connecting piece 441 pushes the sliding column 436 and the protrusion 2 435 to move. In the process that the inclined surface of the protrusion 2 435 and the inclined surface of the protrusion 1 434 change from partially overlapping to completely overlapping, the protrusion 1 434 gradually pushes the locking piece 1 433, sliding from a state located inside the positioning cylinder 42 to a state partially protruding outside the positioning cylinder 42, and the locking piece 1 433 and the spring 3 on the inner wall of the positioning cylinder 42 are compressed; when the locking piece 1 433 slides to partially protrude outside the positioning cylinder 42, the outer wall of the locking piece 1 433 is tightly against the inner ring wall of the grinding piece 1 432, and the outer wall of the locking piece 1 433 is provided with a rubber gasket to increase the friction between the inner ring wall of the grinding piece 1 432 and the position of the grinding piece 1 432 is locked.

[0050] The connecting piece 441 pushes multiple arrow pieces 456 to move, and the arrow pieces 456 slide inside the corresponding support plate 453 and approach the corresponding locking piece 2 457. When moving, the arrow-shaped ends of the arrow pieces 456 gradually push the corresponding two locking pieces 2 457 from a state of being close to each other to a state of being away from each other, and the spring four connected between the locking piece 2 457 and the support plate 453 is compressed; when the locking pieces 2 457 are away from each other, the side walls of the locking piece 2 457 are tightly attached to the side walls of the semicircular plate 455, and the side walls of the locking piece 2 457 are provided with rubber gaskets to increase the friction between the side walls of the semicircular plate 455, thereby locking the positions of the semicircular plate 455 and the polishing piece 2 454.

[0051] After the positions of grinding piece 1 432 and grinding piece 2 454 are locked, the output end of motor 2 32 rotates to drive support plate 1 41 to rotate, and the stabilizing slide rail 33 maintains the balance of rotation of support plate 1 41. Support plate 1 41 drives grinding piece 1 432 and multiple grinding pieces 2 454 to fully grind the outer wall of one side of the wheel rim in a self-rotating manner to remove the burrs remaining on the hole wall after punching.

[0052] When the outer wall of one side of the wheel rim is polished, the motor 2 32 stops driving the polishing mechanism 4 for processing, the electric push rod 443 drives the locking piece 1 433 and the locking piece 2 457 to reset, and releases the lock of the polishing piece 1 432 and the polishing piece 2 454, and the support frame 31 drives the polishing mechanism 4 to reset; the column 12 is driven by the electric slider 1 to move on the slide groove 1 of the support seat 11, and the processing table 1 13 and the processing table 2 15 drive a group of wheel rim processing parts on the processing position whose one side has been processed and another group of wheel rim processing parts on the waiting position that have not been processed to rotate ninety degrees and exchange positions.

[0053] A group of wheel rim workpieces whose one side has been processed rotates to the waiting position, and the bottom wall of the output end of the motor 21 corresponding to the waiting position rotates to drive the limit platform 221 on the processing table 2 15 to rotate, and the limited wheel rim and the limit platform 221 on the processing table 13 rotate accordingly, and the torsion spring connected between the limit platform 221 on the processing table 13 and the processing table 13 is stretched to realize a 180-degree flip of the wheel rim in the waiting position, and at this time, another group of wheel rims rotated to the processing position are polished by the driving mechanism 3 and the polishing mechanism 4.

[0054] The wheel rim after flipping and the wheel rim after one grinding process are rotated ninety degrees by the processing table 13 and the processing table 2 15 to exchange positions again. The reverse side of the flipped wheel rim is grinded by the driving mechanism 3 and the grinding mechanism 4 at the processing position, and the wheel rim after one grinding process is flipped by the limiting mechanism 2 at the waiting position. Two are processed simultaneously as a group, and two are processed intermittently as a group to enhance the continuous operation capability of the equipment.

[0055] After all the wheel rims have been polished on both sides, the processing table 2 15 is driven upward by the hydraulic rod 14 to release the limit of multiple wheel rims at the same time, and the adjusting rod 223 is manually pulled, and the adjusting rod 223 approaches the inclined surface of the L-shaped part of the clamping part 222 until the adjusting rod 223 pushes the clamping part 222 to move toward the inner wall of the limit platform 221. The spring is compressed and the clamping part 222 releases the clamping of the wheel rim, so as to facilitate the unloading of the processed wheel rim.

[0056] The specific operation steps of the tubeless wheel rim manufacturing and processing equipment are as follows: Before grinding, the four wheel rims are placed on the corresponding limit platforms 221 on the processing table 13, and the limit platforms 221 at the bottom of the processing table 2 15 and the limit platforms 221 on the processing table 13 limit the wheel rims up and down; the support frame 31 drives the grinding mechanism 4 to move to a suitable position, the grinding piece 1 432 fits with the middle plane of the wheel rim, and the grinding piece 2 454 fits with the middle inclined surface of the wheel rim, and is driven by the electric push rod 443, and the locking piece 1 433 and the locking piece 2 457 lock the positions of the grinding piece 1 432 and the grinding piece 2 454.

[0057] During grinding, the motor 2 32 drives the grinding piece 1 432 and the plurality of grinding pieces 2 454 to grind the outer wall of one side of the wheel rim in a self-rotating manner.
