Description

Technical Field

[0001] The invention relates to the technical field of tire production equipment, in particular to an automatic extruder for balancing weights used in wheel assembly. Background Art

[0002] During the manufacturing and assembly of wheels, it is crucial to ensure the balance of the wheels. Unbalanced wheels will cause vibrations in the vehicle during driving, which will not only affect the ride comfort, but also accelerate the wear of the tires, reduce the service life of vehicle components, and even pose a threat to driving safety. In order to achieve wheel balance, it is necessary to install balance weights on the wheels. The function of the balance weight is to adjust the weight distribution of the wheel so that the wheel reaches a dynamic balance state when rotating, thereby reducing vibration and improving driving stability.

[0003] Currently, the existing automatic extrusion machines for balancing weights for wheel assembly mostly rely on manual operation for the traditional installation method of balancing weights. When the balancing weights are manually pasted, it is difficult to ensure that the force of each pasting is consistent, which will affect the installation quality of the balancing weights. In addition, after the staff tears off the adhesive film on one side of the balancing weight, they manually paste it on the inner wall surface of the wheel hub. During this process, the balancing weight is easily distorted when pasted on the inner wall surface of the wheel hub, resulting in low stability and efficiency of the entire installation process, thereby destroying the dynamic balance state of the wheel hub.

[0004] Therefore, there is an urgent need for an automatic extruder for wheel assembly balancing weights to solve the problems of the prior art. Summary of the invention

[0005] The object of the present invention is to provide an automatic extruder for balancing weights for wheel assembly to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides an automatic extruder for balancing weights for wheel assembly, comprising a workbench, a mounting plate, a clamping mechanism, a lifting mechanism and an extrusion mechanism; The workbench includes a transmission roller, which is rotatably connected to the upper surface of the workbench, and support legs are fixedly installed around the bottom of the outer surface of the workbench; The clamping mechanism includes a hydraulic assembly and a clamp, the clamp is telescopically adjusted at the center position of the upper surface of the transmission roller through the hydraulic assembly, and the front end surface of the clamp is parallel to the front end surface of the guide roller; The lifting mechanism includes a press-fit assembly, a collar and a clamping block, wherein the collar and the clamping block are symmetrically distributed on both sides of the lower surface of the press-fit assembly, the lower surface of the clamping block is vertically corresponding to the inner wall of the wheel hub, and the clamping block moves downward through the press-fit assembly to be in compression contact with the inner wall of the wheel hub; The extrusion mechanism includes a touch-pressure unit and an extrusion box. The extrusion box is slidably installed inside the card block. A balancing block is movably connected inside the extrusion box. The balancing block squeezes the extrusion box through the touch-pressure unit, so that the balancing block is pushed outward of the card block along with the extrusion box, and one side of the balancing block surface is parallel to the card block surface, so that the balancing block is finally squeezed onto the inner wall surface of the wheel hub.

[0008] As a further improvement of the present technical solution, the touch-pressure unit includes a through groove, which is arranged at the center position of the upper surface of the card block, a guide rail is fixedly installed at the center position of the inner bottom of the card block, an extrusion box is slidably connected to the upper surface of the guide rail, slide rails are fixedly installed on both sides of the surface of the extrusion box, a slider is slidably connected to the surface of the slide rail, a seesaw is fixedly connected to the back surface of the slider, connecting parts are rotatably connected to the surface of the seesaw, a reset spring 2 is fixedly connected to one side of the surface of the seesaw, a push rod is fixedly installed on one side of the surface of the reset spring 2, a contact block is fixedly installed on the front end surface of the slider, bearings are rotatably connected to both sides of the surface of the extrusion box, an extrusion block is fixedly connected to one side of the bearing surface, and a folding plate is fixedly connected to the front end surface of the bearing.

[0009] As a further improvement of the present technical solution, the slider slides toward the inner side of the block through the slide rail, generating thrust on both sides of the seesaw surface, and under the rotation action of the connecting piece, the center position of the seesaw moves toward the center position of the back side of the extrusion box, and generates thrust on the extrusion box through the push rod, sliding on the upper surface of the guide rail toward the outer side of the block, and the second reset spring can generate an inward pulling force on one side of the seesaw, and at the same time, the contact block and the slider slide synchronously toward the inner side of the block, and are in compression contact with the surface of the extrusion block, and under the rotation action of the bearing, the folding plate is driven to bend and open on both sides of the extrusion box surface. Since a balancing block is clamped inside the extrusion box, the balancing block can be pushed from the inside of the extrusion box to the surface of the block, and a sleeve rod is fixedly connected to one side of the surface of the second reset spring, and the sleeve rod is telescopically sleeved on one side of the push rod surface.

[0010] As a further improvement of the present technical solution, the hydraulic assembly includes a fixed plate, a hydraulic pump is fixedly installed on one side of the surface of the fixed plate, a hydraulic telescopic rod is fixedly connected to one side of the surface of the hydraulic pump, a clamp is fixedly connected to one side of the surface of the hydraulic telescopic rod, and a card slot is opened at the center position of the clamp surface.

[0011] As a further improvement of the technical solution, the mounting plates are fixedly mounted on both sides of the upper surface of the transmission roller, the upper surface of the mounting plates is fixedly mounted with connecting plates, and the lower surface of the connecting plates is rotatably connected with guide rollers.

[0012] As a further improvement of the technical solution, a driving motor is fixedly installed on one side of the lower surface of the workbench, and a chain is fixedly connected to one side of the surface of the transmission roller. The driving motor drives the transmission roller to rotate on the surface of the workbench through the chain, and the surface of the transmission roller transmits the wheel hub.

[0013] As a further improvement of the present technical solution, the two sides of the wheel hub surface are in rotational contact with the guide roller surface. When the wheel hub is positioned and transmitted to the center position of the clamp surface through the transmission roller and the guide roller, the clamp clamps and engages the two sides of the wheel hub surface through the hydraulic assembly.

[0014] As a further improvement of the present technical solution, the clamp clamps the wheel hub at the center position of the upper surface of the transmission roller, and the clamping block moves downward through the hydraulic assembly, first through the clamping contact between the clamping ring and the outer surface of the wheel hub on both sides, and then continues to squeeze downward, and uses the sleeve and the return spring to drive the clamping ring to rotate and adjust on the outer surface of the rotating rod, and at the same time drives the sleeve rod to rotate and adjust toward the inner wall of the wheel hub, and finally allows the clamping block to be squeezed and attached to the inner wall surface of the wheel hub.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The automatic extruder for balancing weights for wheel assembly clamps and tightens the wheel hub through a clamp, and uses a hydraulic component to first lower the clamping ring to both sides of the upper surface of the wheel hub, so that the clamping ring fits the outer surface of the wheel hub, and when the clamping ring is further squeezed downward, the clamping ring is effectively clamped on the upper surface of the wheel hub, avoiding the problem of unstable installation when squeezing the wheel hub to install the balancing weight during the vehicle, and also facilitating the subsequent clamping block to be accurately attached to the inner wall surface of the wheel hub.

[0016] 2. The automatic extruder for balancing weights for wheel assembly, when the clamping ring is clamped on both sides of the upper surface of the wheel hub and continues to be squeezed downward, the sleeve rotates on the outer surface of the rotating rod, and the sleeve rod synchronously rotates on the outer surface of the rotating rod and rotates toward the inner wall surface of the wheel hub, thereby effectively attaching the clamping block to the inner wall surface of the wheel hub, so that the balancing weight clamped inside the clamping block is adhered to the inner wall of the wheel hub, which can ensure that the balancing weight is vertically extruded and installed on the inner wall surface of the wheel hub, effectively avoiding the problem of distorted pasting of the balancing weight on the inner wall surface of the wheel hub due to manual pasting, resulting in low stability and efficiency of the entire installation process, thereby destroying the dynamic balance state of the wheel hub.

[0017] 3. The automatic extrusion machine for balancing weights for wheel assembly generates thrust on the extrusion box through the push rod, which slides toward the outside of the block on the upper surface of the guide rail. The two reset springs generate inward pulling force on one side of the seesaw. At the same time, the contact block and the slider slide toward the inside of the block synchronously, and are in contact with the surface of the extrusion block. Under the rotation of the bearing, the folding plates are driven to bend and open on both sides of the extrusion box surface. Since the extrusion box is clamped with a balancing weight, the balancing weight can be pushed from the inside of the extrusion box to the side of the block surface, and finally pasted on the inner wall surface of the wheel hub, which is convenient for the staff to place the balancing weight in an orderly manner and ensure the normal extrusion and installation of the balancing weight on the wheel hub.

DETAILED DESCRIPTION

[0020] The following will be combined with the accompanying drawings in 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.

[0021] See also Figure 1 - Figure 5 and Figure 8 As shown, the purpose of this embodiment is to provide an automatic extrusion machine for balancing weights for wheel assembly, including a workbench 100, a mounting plate 200, a clamping mechanism 300, a lifting mechanism 400 and an extrusion mechanism 500; The workbench 100 includes a transmission roller 102, which is rotatably connected to the upper surface of the workbench 100, and support legs 101 are fixedly installed around the bottom of the outer surface of the workbench 100; The clamping mechanism 300 includes a hydraulic assembly and a clamp 304. The clamp 304 is telescopically adjusted at the center position of the upper surface of the transmission roller 102 by the hydraulic assembly. The front end surface of the clamp 304 is parallel to the front end surface of the guide roller 202. The lifting mechanism 400 includes a press-fit assembly, a collar 405 and a clamping block 411. The collar 405 and the clamping block 411 are symmetrically distributed on both sides of the lower surface of the press-fit assembly. The lower surface of the clamping block 411 is vertically corresponding to the inner wall of the wheel hub. The clamping block 411 moves downward through the press-fit assembly and is in compression contact with the inner wall of the wheel hub. The extrusion mechanism 500 includes a contact and pressure unit and an extrusion box 502. The extrusion box 502 is slidably mounted inside the clamping block 411. A balancing weight is movably clamped inside the extrusion box 502. The balancing weight presses the extrusion box 502 through the contact and pressure unit, so that the balancing weight is pushed outward of the clamping block 411 along with the extrusion box 502, and one side of the surface of the balancing weight is parallel to the surface of the clamping block 411, so that the balancing weight is finally pressed against the inner wall surface of the wheel hub. The wheel hub is transmitted by the transmission roller 102 and transmitted to the surface position of the clamp 304, and the hydraulic component is started to drive the clamp 304 to retract toward both sides of the wheel hub surface. After the clamp 304 clamps and tightens the wheel hub, the press-fit component is started to drive the clamp ring 408 to press down and clamp it on both sides of the upper surface of the wheel hub, and continue to squeeze downward. Under the rotational force, the clamp block 411 is rotated and adjusted toward both sides of the inner wall of the wheel hub, and finally attached to the inner wall surface of the wheel hub. When the clamp block 411 contacts the inner wall surface of the wheel hub, the extrusion box 502 is driven to slide toward the outer surface of the clamp block 411 through the touch-pressure unit, and the balancing block clamped inside the extrusion box 502 is attached to the wheel hub surface. When the balancing block is attached to the inner wall surface of the wheel hub, the press-fit component rises, effectively separating the clamp ring 408 from the upper surface of the wheel hub, and separating the clamp block 411 from the inner wall surface of the wheel hub.

[0022] It should be noted that a driving motor is fixedly installed on one side of the lower surface of the workbench 100, and a chain is fixedly connected to one side of the surface of the transmission roller 102. The driving motor drives the transmission roller 102 to rotate on the surface of the workbench 100 through the chain, effectively allowing the wheel hub to be transmitted on the upper surface of the transmission roller 102.

[0023] Therefore, based on the above structure, combined with Figure 5-Figure 7 As shown, the structure of the press-fit assembly is further disclosed, the hydraulic assembly includes a support frame 401, a top plate 402 is fixedly installed on the upper surface of the support frame 401, a hydraulic pump 403 is fixedly installed at the center position of the upper surface of the top plate 402, a hydraulic telescopic rod 404 is fixedly connected to the lower surface of the hydraulic pump 403, a collar 405 is fixedly sleeved on the lower surface of the hydraulic telescopic rod 404, connecting rods 406 are fixedly connected on both sides of the outer surface of the collar 405, a rotating rod is rotatably sleeved at the center position of one side of the surface of the connecting rod 406, a sleeve 407 is fixedly sleeved on the outer surface of the rotating rod, a clamping ring 408 is fixedly connected on one side of the surface of the sleeve 407, a reset spring 410 is fixedly connected on both sides of the outer surface of the rotating rod, a sleeve connecting rod 409 is fixedly sleeved on both sides of the surface of the sleeve connecting rod 407, and a clamping block 411 is fixedly connected to one side of the surface of the sleeve connecting rod 409; Furthermore, by starting the second hydraulic pump 403, the second hydraulic telescopic rod 404 is driven to descend, and the collar 405 is driven to move downward synchronously, so that the clamping ring 408 fits with both sides of the upper surface of the wheel hub. When the second hydraulic telescopic rod 404 continues to be pressed down, the clamping ring 408 remains stationary, and the sleeve 407 is used to drive the rotating rod to rotate on the surface of the connecting rod 406. Since the sleeve rod 409 is fixedly sleeved on both sides of the rotating rod surface, the sleeve rod 409 drives the clamping block 411 to rotate and adjust to both sides of the inner wall of the wheel hub. The initial position is distributed at a downward angle of 45° on both sides of the inner wall of the wheel hub. Therefore, when the rotating rod drives the sleeve rod 409 to rotate and the hydraulic telescopic rod 404 is lowered to the lowest height, the clamping block 411 can be vertically attached to the inner wall surface of the wheel hub. The automatic extrusion installation method of the balancing block replaces the manual pasting of the balancing block on the inner wall surface of the wheel hub by the staff, and the installation position of the balancing block is positioned and clamped, which avoids the problem of the balancing block being distorted when pasted on the inner wall surface of the wheel hub, and effectively improves the work efficiency; It should be noted that the reset spring 1 410 can reduce the rotation speed of the rotating rod. At the same time, after the hydraulic telescopic rod 2 404 drives the clamping ring 408 to reset upward, the clamping block 411 can also rebound to achieve a reset effect.

[0024] Therefore, based on the above structure, combined with Figure 8-Figure 10 As shown, the structure of the touch-pressure unit is further disclosed, the touch-pressure unit includes a through slot 501, the through slot 501 is arranged at the center position of the upper surface of the card block 411, a guide rail 503 is fixedly installed at the center position of the inner bottom of the card block 411, an extrusion box 502 is slidably connected to the upper surface of the guide rail 503, slide rails 504 are fixedly installed on both sides of the surface of the extrusion box 502, a slider 505 is slidably connected to the surface of the slide rail 504, a seesaw 506 is fixedly connected to the back surface of the slider 505, and connecting members 507 are rotatably connected to the surface of the seesaw 506, a return spring 2 508 is fixedly connected to one side of the surface of the return spring 2 508, a push rod 509 is fixedly installed on one side of the surface of the return spring 2 508, a contact block 510 is fixedly installed on the front end surface of the slider 505, bearings 512 are rotatably connected to both sides of the surface of the extrusion box 502, an extrusion block 511 is fixedly connected to one side of the surface of the bearing 512, and a folding plate 513 is fixedly connected to the front end surface of the bearing 512; Furthermore, by contacting the inner wall surface of the wheel hub with the block 411, the slider 505 is first contacted with the inner wall surface of the wheel hub. Under the action of the extrusion force, the slider 505 slides inward on the surface of the slide rail 504, and drives both sides of the seesaw 506 connected to the back surface of the slider 505 to move inwardly toward the block 411. Under the connection action of the connecting piece 507, the center position of the seesaw 506 moves outwardly toward the block 411, so that the center position of one side of the seesaw 506 generates an outward thrust on the push rod 509, and effectively allows the push rod 509 to move outwardly. 09 generates a thrust to the outside of the block 411 on the extrusion box 502, and a sleeve rod is fixedly connected to one side of the surface of the reset spring 508, and the sleeve rod is telescopically sleeved on one side of the surface of the push rod 509. At the same time, the reset spring 508 is fixedly connected to one side of the surface of the push rod 509, which has a certain deceleration effect on the thrust of the push rod 509. After the seesaw 506 is reset, the reset spring 508 can also make the push rod 509 rebound to its original position, which is convenient for placing the balance weight inside the extrusion box 502 and squeezing it again to be installed in the wheel hub. The wall surface makes the extrusion box 502 slide on the upper surface of the guide rail 503, and at the same time, the contact block 510 set on the front end surface of the slider 505 contacts and squeezes the extrusion blocks 511 set on both sides of the front end of the extrusion box 502. Under the connection of the bearing 512, the extrusion block 511 drives the folding plate 513 to expand outward on both sides of the front end surface of the extrusion box 502, so that the balance block clamped inside the extrusion box 502 is displayed on the front end surface of the clamping block 411, and slides to the front end of the clamping block 411 as the extrusion box 502. At this time, the clamping block 411 is attached to the vehicle. The inner wall surface of the wheel hub, and finally the balancing weight can be adhered to the inner wall surface of the wheel hub. After the block 411 and the inner wall surface of the wheel hub are separated, the reset spring 2 508 can drive the extrusion box 502 to reset and correspond vertically to the through groove 501. The folding plate 513 resets and continues to position and clamp the balancing weight in the extrusion box 502. At the same time, the slider 505 also extends from the front end surface of the slide rail 504 along with the seesaw 506, which is convenient for subsequent contact and extrusion with the inner wall surface of the wheel hub, and the balancing weight is extruded and installed on the inner wall surface of the wheel hub; It should be noted that: one side of the balancing block is adhered with glue, and the balancing block with glue is placed on the front surface of the extrusion box 502 and the clamping block 411, and the balancing block is placed into the extrusion box 502 from the through slot 501, and the thickness and length and width of the extrusion box 502 are adapted to the thickness and length and width of the balancing block, so that the staff can clamp the balancing block into the extrusion box 502 to avoid the problem of misplacement; Therefore, based on the above structure, combined with Figure 3As shown, the structure of the hydraulic assembly is further disclosed, the hydraulic assembly includes a fixed plate 301, a hydraulic pump 302 is fixedly installed on one side of the surface of the fixed plate 301, a hydraulic telescopic rod 303 is fixedly connected to one side of the surface of the hydraulic pump 302, a clamp 304 is fixedly connected to one side of the surface of the hydraulic telescopic rod 303, and a card slot 305 is opened at the center of the surface of the clamp 304; Furthermore, by starting the hydraulic pump 302, the hydraulic telescopic rod 303 drives the clamp 304 to retract toward the center position of the upper surface of the transmission roller 102, clamps and fastens the wheel hub transmitted by the upper surface of the transmission roller 102, and vertically corresponds to the press-fit assembly installed on the upper surface of the center position of the transmission roller 102, so as to facilitate the subsequent squeezing of the balance block on the inner wall surface of the wheel hub; It should be noted that: laser sensors are installed around the clamp 304, and the laser transmitter emits a laser beam to the target (wheel hub). When the laser beam is irradiated to the surface of the wheel hub, it will be reflected, and the reflected light is received by the receiver, driving the hydraulic pump 302, pushing the hydraulic telescopic rod 303, so that the clamp 304 shrinks and clamps and tightens the two sides of the wheel hub.

[0025] Therefore, based on the above structure, combined with Figure 2 The structure of the mounting plate 200 is further disclosed as shown. The mounting plate 200 is fixedly mounted on both sides of the upper surface of the transmission roller 102. A connecting plate 201 is fixedly mounted on the upper surface of the mounting plate 200. A guide roller 202 is rotatably connected to the lower surface of the connecting plate 201. Furthermore, the transmission roller 102 is in operation to transmit the wheel hub, and the guide roller 202 is arranged to position the transmission direction of the wheel hub, so that the wheel hub always maintains linear motion, and the clamp 304 can effectively clamp the wheel hub accurately, and play a certain stability when squeezing the balance weight on the inner wall of the wheel hub; In summary, the working principle of this solution is as follows: the staff tears off the film with glue on one side of the balancing weight, and places the balancing weight with glue on one side from the through slot 501 to the center of the extrusion box 502, and clamps the balancing weight inside the extrusion box 502 through the folding plate 513; The wheel hub is placed on the upper surface of the transmission roller 102, a driving motor is fixedly installed on one side of the lower surface of the workbench 100, and a chain is fixedly connected to one side of the surface of the transmission roller 102. The driving motor drives the transmission roller 102 to rotate on the surface of the workbench 100 through the chain. The surface of the transmission roller 102 transmits the wheel hub. At the same time, the guide roller 202 can position the transmission direction of the wheel hub, so that the wheel hub always maintains linear motion. When the wheel hub is transmitted to the center position of the upper surface of the transmission roller 102, it corresponds to the clamp 304 in parallel. The laser sensor senses the wheel hub, drives the hydraulic pump 302, and pushes the hydraulic telescopic rod 303 to shrink the clamp 304 to the center position of the upper surface of the transmission roller 102, and clamps and tightens the two sides of the wheel hub; After the clamp 304 clamps and tightens the wheel hub, the hydraulic pump 403 is started to drive the hydraulic telescopic rod 404 to descend, and simultaneously drive the collar 405 to move downward, effectively making the lower surface of the collar 408 and the upper surface of the wheel hub on both sides clamped, while continuing to press downward, the collar 408 remains stationary, the sleeve 407 drives the rotating rod to rotate, and the sleeve rod 409 is synchronously rotated and adjusted, so that the clamping block 411 is rotated and adjusted toward the inner wall surface of the wheel hub. When the hydraulic telescopic rod 404 descends to the lowest height, the clamping block 411 is also in contact with the inner wall surface of the wheel hub; When the block 411 fits with the inner wall surface of the wheel hub, the slider 505 contacts the inner wall surface of the wheel hub first. Under the action of the extrusion force, the slider 505 slides inward on the surface of the slide rail 504, and drives the two sides of the seesaw 506 connected to the back surface of the slider 505 to move inward of the block 411. Under the connection of the connecting piece 507, the center position of the seesaw 506 moves outward of the block 411, and the push rod 509 effectively generates a thrust force on the squeeze box 502 toward the outside of the block 411, so that the squeeze box 502 is on the guide rail 503. The surface slides, and at the same time, the contact block 510 set on the front end surface of the slider 505 and the extrusion blocks 511 set on both sides of the front end of the extrusion box 502 contact and extrude. Under the connection action of the bearing 512, the extrusion block 511 drives the folding plate 513 to expand outward on both sides of the front end surface of the extrusion box 502, so that the balancing block clamped inside the extrusion box 502 is displayed on the front end surface of the clamping block 411, and slides to the front end of the clamping block 411 as the extrusion box 502, at this time, the clamping block 411 is attached to the inner wall surface of the wheel hub, and finally the balancing block can be adhered to the inner wall surface of the wheel hub.
