Description

Technical Field

[0001] The present invention relates to the technical field of tire balancing machines, and in particular to a tire balancing machine and a control method thereof. Background Art

[0002] Tire balancing machines are mainly used to detect and calibrate the imbalance of vehicle tires. When the vehicle is traveling at a high speed, the imbalance of the tires will cause vibration, increased noise and uneven tire wear. The tire balancing machine installs sensors on the tires to detect the imbalance points of the tires and achieves tire balance by adjusting the counterweights on the tires.

[0003] After searching, Chinese patent publication number CN117870961A discloses a bias tire dynamic balancing machine, including a tire dynamic balancing machine body, a test control panel, a rotating shaft assembly and a locking handle. The tire dynamic balancing machine body is installed on the ground, and the test control panel is fixedly installed on the top of the tire dynamic balancing machine body. The above solution ensures that the bias tire is firmly installed on the rotating shaft assembly by tightly holding the bias tire against the mounting support block and locking it with the locking handle. By using the tire dynamic balancing machine body and the tire fastening mechanism, the rotation speed of the bias tire can be ensured to be consistent with the rotation speed of the rotating shaft assembly, thereby avoiding errors caused by inconsistent rotation speeds. The mounting support block can increase the friction force on the bias tire by tightening the support block when rotating at high speed, thereby preventing the bias tire from sliding or loosening when rotating at high speed. However, the above solution still has the following shortcomings in actual use:

[0004] When the tire balancing machine proposed in the above scheme is actually used, the staff needs to install the tires on the test spindle of the balancing machine. Since the tires are of a certain weight, manually lifting these tires will consume a lot of physical strength of the staff. Performing such operations for a long time can easily lead to fatigue and may even cause work-related accidents. In addition, when manually lifting the tires, if the staff fails to correctly grasp the balance or uses improper force, the tire may fall, which will not only damage the equipment but also cause harm to the staff.

[0005] Therefore, it is necessary to design a tire balancing machine and a control method thereof to solve the above problems. Summary of the Invention

[0056] A control method for a tire balancing machine comprises the following steps:

[0057] Step 1: Tire installation and tightening

[0058] a. Preparation: Ensure the scissor-type hydraulic lift is in the lowest position and the slide is away from the tire balancing equipment;

[0059] b. Tire placement: The staff lifts the tire onto the fixed frame and places it between the two rollers and two rotating arms;

[0060] c. Tire compression: The worker presses down on the pedal, squeezing the bladder through the lifting plate, causing the liquid medium to push the slide plug to move, which in turn drives the rotating arms to rotate synchronously and move closer to each other until the two compression blocks press the tire together, completing the tire compression and fixation;

[0061] Step 2: Tire lifting and positioning

[0062] a. Tire lifting: The staff uses the scissor-type hydraulic lifting device to lift the tire until it rises to a position facing the main drive shaft of the tire balancing equipment;

[0063] b. Tire positioning: The staff pushes the fixed frame to drive the slide on the slide rail until the tire is placed on the driving spindle of the tire balancing equipment;

[0064] c. Fixing the tire: The staff fixes the tire on the driving spindle of the tire balancing equipment to complete the tire installation;

[0065] Step 3: Tire cleaning preparation

[0066] a. Release the pedal: When the operator releases the pedal, the lifting plate moves upward and resets under the elastic force of the bladder itself and the two first springs. Simultaneously, the two rotating arms rotate synchronously and away from each other, separating the two pressing blocks from the tire.

[0067] b. Adjust the position: The staff pulls the fixed frame to move the two rotating arms away from the tire balancing equipment in preparation for tire cleaning;

[0068] Step 4: Tire cleaning

[0069] a. Step on the pedal again: The staff member steps on the pedal again, causing the lifting plate to descend to a position where it contacts the two blocks. At this point, the bristles on the two rotating arms contact the tire surface.

[0070] b. Start cleaning: The staff starts the tire balancing equipment to rotate the tire. At the same time, the bristles on the two rotating arms continuously brush the tire surface to remove impurities such as stones on the tire;

[0071] c. Dust collection: The suction piece rotates with the tire, and absorbs the dust generated during the cleaning process through the suction port. The dust enters the filter barrel and is intercepted by the filter element;

[0072] Step 5: Cleaning and Resetting

[0073] a. Continue to step on the pedal: The staff continues to step on the pedal to make the lifting plate continue to move downward, squeezing the inclined surface of the stopper so that the stopper retracts into the groove to avoid movement interference;

[0074] b. Reset operation: Release the pedal, the lifting plate moves up and resets under the thrust of the capsule, and the two slides reset under the elastic force of the first spring, returning the liquid medium back to the capsule;

[0075] c. Arrange equipment: The staff will arrange the fixed frame, rotating arm and other components to ensure that the equipment is in good condition and prepare for the next use.

[0076] The present invention has the following beneficial effects:

[0077] 1. The bladder extrusion drives the rotating arm and the pressing block, realizing the automatic pressing and fixing of the tire. There is no need for manual lifting of the tire, which greatly reduces the physical exertion of the workers. At the same time, the introduction of the scissor-type hydraulic lifting device makes it easy to lift the tire, further reducing manual operation. The device avoids potential safety hazards such as falling and sprains during the lifting and handling of the tire through mechanized operation, effectively protecting the safety of the workers.

[0078] 2. The hard bristles can effectively remove loose stones stuck in the tire tread, preventing these stones from being thrown out when the tire rotates at high speed, thereby avoiding possible injuries to workers caused by stones. This is the most important function of the cleaning structure, ensuring safety during the inspection process. In addition, the existence of the cleaning structure helps to keep the tire surface clean, reduce the interference of stones and other impurities on the tire balance test results, thereby improving the accuracy and reliability of the test;

[0079] 3. The rotation of the suction piece and the pumping action of the axial flow blades can efficiently absorb the dust generated during the tire cleaning process, ensuring a clean working environment. This design intercepts the dust through the filter element, avoiding direct discharge of dust, meeting environmental protection requirements. At the same time, since the suction piece is driven by the rotation of the tire, no additional energy consumption is required, reflecting the characteristics of energy saving.

DETAILED DESCRIPTION

[0092] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0093] Reference Figure 1-11 A tire balancing machine includes a tire balancing device 1; a scissor-type hydraulic lifting device 2, which is installed on the tire balancing device 1. The specific structure and working principle of the tire balancing device 1 and the scissor-type hydraulic lifting device 2 are not an innovative part of the present technical solution and are not shown in the figure and will not be described in detail here; a mounting plate 3, which is fixed to the lifting part of the scissor-type hydraulic lifting device 2; a slide rail 4, which is fixed to the top surface of the mounting plate 3; a slide seat 5, which is slidably assembled on the slide rail 4; and a fixing frame 6, which is fixed to the top surface of the slide seat 5;

[0094] The tire balancing machine also includes a pressing structure, which is arranged on the fixed frame 6. The pressing structure includes: two rotating arms 71, both of which are rotatably mounted on the fixed frame 6. The two rotating arms 71 are both arc-shaped structures. The interior of each rotating arm 71 is a hollow structure. The internal spaces of the two rotating arms 71 are connected by a hose; two pressing blocks 72 are respectively fixed to the ends of the two rotating arms 71 away from the fixed frame 6; a plurality of bristles 73 are respectively bonded to the opposite sides of the two rotating arms 71; and a plurality of suction ports 74 are respectively opened on the opposite sides of the two rotating arms 71.

[0095] The tire balancing machine also includes two connecting structures, both of which are arranged on the fixing frame 6. The two pressing structures are connected to the fixing frame 6 through the connecting structure. The connecting structure includes: a sealing cylinder 81, one end of which is rotatably mounted on the fixing frame 6, and one end of the sealing cylinder 81 is provided with a through hole; a sliding plug 82, which is sealingly and slidingly connected to the inner surface of the sealing cylinder 81; a first spring 83, one end of which is connected to the inner surface of the sealing cylinder 81 and the other end is connected to the sliding plug 82; a connecting rod 84, one end of which is fixedly connected to the sliding plug 82 and the other end extends to the outside of the sealing cylinder 81 through the through hole; a connecting plate 85, one end of which is fixedly connected to the sliding plug 82 and the other end extends to the outside of the sealing cylinder 81; One end of the connecting rod 84 is rotatably connected to the outside of the sealing cylinder 81, and the other end is rotatably mounted on the rotating arm 71. When the liquid medium enters the interior of the sealing cylinder 81, the liquid medium can push the sliding plug 82 to move, and the movement of the sliding plug 82 can drive the connecting rod 84 to move. Since the sealing cylinder 81 is rotatably mounted on the fixed frame 6, the end of the connecting rod 84 located outside the sealing cylinder 81 is rotatably connected to the connecting plate 85, and the end of the connecting plate 85 away from the connecting rod 84 is rotatably connected to the rotating arm 71. Therefore, when the sliding plug 82 and the connecting rod 84 move, the rotating arm 71 can rotate.

[0096] The tire balancing machine also includes a driving structure, which is arranged on the tire balancing device 1 and is used to drive the two connecting structures to operate. The driving structure includes: a mounting box 91, which is fixed to the tire balancing device 1; a lifting plate 92, which is slidably arranged inside the mounting box 91; two guide rods 93, both of which are fixed inside the mounting box 91, and the lifting plate 92 is slidably sleeved on the two guide rods 93; a capsule 94, one end of which is connected to the inner surface of the mounting box 91 and the other end is connected to the lifting plate 92, and two connecting pipes are connected to the capsule 94, and the ends of the two connecting pipes away from the capsule 94 are respectively connected to the two sealing cylinders 8 1 is connected, and the interior of the bladder 94 accumulates a liquid medium; a pedal 95 is fixed to the side of the lifting plate 92; a slide 96 is provided on the side of the mounting box 91, and the pedal 95 slides in the slide 96. When the lifting plate 92 moves downward, it can squeeze the bladder 94. When the bladder 94 is squeezed, the liquid medium inside it will enter the interior of the two sealing cylinders 81 respectively through the two connecting pipes. When the bladder 94 is squeezed, the two rotating arms 71 can rotate synchronously and approach each other until the two pressing blocks 72 jointly press the tire, and the tire is compressed and fixed by the two pressing blocks 72;

[0097] Two blocking structures are both arranged on the inner surface of the installation box 91, and the blocking structure includes: a groove 121, which is opened on the inner surface of the installation box 91; a stopper 122, which is slidably arranged in the groove 121, and one end of the stopper 122 extends to the outside of the groove 121, and the end of the stopper 122 located outside the groove 121 is provided with two inclined surfaces with opposite inclined directions, and the two stops 122 are arranged opposite to each other; a second spring 123, one end of which is connected to the groove wall of the groove 121, and the other end is connected to the stopper 122. Since the stopper 122 is provided with two inclined surfaces, the lifting plate 92 can squeeze the inclined surface of the stopper 122 when it moves downward. When the stopper 122 is squeezed, it can move and retract into the groove 121. The movable feature of the stopper 122 can avoid the situation where the stopper 122 and the lifting plate 92 interfere with each other in movement.

[0098] The tire balancing machine also includes two rolling structures, both of which are arranged on the fixed frame 6. The rolling structure includes: a mounting frame 101, which is fixed on the fixed frame 6 and has a U-shaped structure; a rotating shaft 102, which is rotatably mounted on the mounting frame 101; a roller 103, which is fixedly sleeved on the rotating shaft 102, and a dust suction structure is provided on one of the mounting frames 101. The dust suction structure includes: an air suction cylinder 111, which is fixed to the side of the mounting frame 101 through a rod body, and an exhaust port is opened on the air suction cylinder 111; a shaft 112 , placed inside the suction cylinder 111, one end of which is fixedly connected to the rotating shaft 102; the suction member 113 is fixed to the end of the shaft 112 away from the rotating shaft 102, and the suction member 113 includes a sleeve and a plurality of axial flow blades, the sleeve is fixedly sleeved on the shaft 112, and the plurality of axial flow blades are fixed on the sleeve, and the plurality of axial flow blades are distributed in a circumferential array around the shaft 112; the air guide cover 114 is fixed to the end of the suction cylinder 111 away from the mounting frame 101, and is connected to the interior of the suction cylinder 111; the exhaust pipe 115 , one end is connected to the air guide cover 114; the filter cartridge 116 is installed on the fixing frame 6, one end of the filter cartridge 116 is connected to the end of the exhaust pipe 115 away from the air guide cover 114, and the other end of the filter cartridge 116 is connected to the interior of one of the rotating arms 71 through the air pipe; the filter element 117 is installed in the interior of the filter cartridge 116, and as the tire rotates, the two rollers 103 will also rotate, which makes the two rotating shafts 102 also rotate. When the two rotating shafts 102 rotate, one of the rotating shafts 102 can drive the shaft 112 to rotate, which makes the suction member 113 rotate, and a number of axial flow blades are provided in the suction member 113. When the axial flow blades rotate, they can perform an exhaust action. Therefore, when the suction member 113 rotates, the two suction ports 74 on the two rotating arms 71 can absorb dust generated during the tire cleaning process, and the dust will enter the filter cartridge 116 under the suction action of the suction member 113 and finally be intercepted by the filter element 117. This design can play a role in cleaning the dust generated during the tire cleaning process.

[0099] The specific working principle of the present invention is as follows:

[0100] When the tire balancing machine proposed by the present invention is actually used, the lifting part of the scissor-type hydraulic lifting device 2 is located at the lowest end. At this time, the distance between the lifting part of the scissor-type hydraulic lifting device 2 and the ground is the shortest. In addition, the slide 5 is located far away from the tire balancing device 1. When the tire needs to be installed on the driving spindle of the tire balancing device 1, the staff first lifts the tire onto the fixed frame 6, places the tire on the two rollers 103, and places the tire between the two rotating arms 71. Then the staff steps on the pedal 95 downward, so that the pedal 95 drives the lifting plate 92 to move downward. When the lifting plate 92 moves downward, it can squeeze the bladder 94. When the bladder 94 is squeezed, the liquid medium inside it will enter the interior of the two sealing cylinders 81 respectively through the two connecting pipes. When the liquid medium enters the interior of the sealing cylinder 81, the liquid medium can push the sliding plug 82 to move. When the sliding plug 82 moves, it can drive the connecting rod 84 to move. Since the sealing cylinder 81 is rotatably installed on the fixed frame 6, the end of the connecting rod 84 located outside the sealing cylinder 81 is rotatably connected to the connecting plate 85, and the connecting plate 85 is away from the connecting rod. One end of the connecting rod 84 is rotatably connected to the rotating arm 71, so when the slide plug 82 and the connecting rod 84 move, the rotating arm 71 can rotate. Based on the above process, when the bladder 94 is squeezed, the two rotating arms 71 can rotate synchronously and approach each other until the two pressing blocks 72 jointly press the tire, and the tire is pressed and fixed by the two pressing blocks 72. Then, the staff uses the scissor-type hydraulic lifting device 2 to lift the tire until the tire rises to a position facing the driving main shaft of the tire balancing device 1. Further, the staff pushes the fixing frame 6. When the fixing frame 6 moves, it can drive the slide 5 to move, so that the slide 5 slides on the slide rail 4 until the tire is set on the driving main shaft of the tire balancing device 1. Finally, the staff fixes the tire on the driving main shaft of the tire balancing device 1, and the tire can be installed on the tire balancing device 1. The device has the function of lifting the tire, and the staff does not need to lift the tire onto the main shaft of the tire balancing device 1, which can reduce the physical exertion of the staff and avoid the tire falling during the lifting process, thereby ensuring the safety of the operation.

[0101] After the tire is fixed to the driving spindle of the tire balancing device 1, the staff releases the pedal 95, causing the lifting plate 92 to move upward and reset under the action of the elastic force of the bladder 94 itself. At the same time, the two slide plugs 82 are also reset with the elastic force of the two first springs 83. When the two slide plugs 82 are reset, the two rotating arms 71 can be rotated synchronously and moved away from each other, so that the two pressing blocks 72 are separated from the tire. Then, the staff pulls the fixing frame 6, so that the fixing frame 6 drives the two rotating arms 71 away from the tire balancing device 1 until the two rotating arms 71 are separated, thereby completing the separation operation between the tire and the two rotating arms 71.

[0102] In addition, the device also has the function of cleaning the tire. After the tire is installed on the driving spindle of the tire balancing device 1, the staff releases the pedal 95. When the lifting plate 92 is reset to the top position of the mounting box 91, the two rotating arms 71 will separate from the tire. Then the staff steps on the pedal 95 again to move the lifting plate 92 downward. The lifting plate 92 will contact the two opposite blocks 122 during the descent. At this time, the staff can sense the resistance from the two blocks 122. In this case, the staff stops applying force to the pedal 95 to stop the lifting plate 92 in the position in contact with the two blocks 122. At this time, the two pressing blocks 72 will not contact the tire, but the several bristles 73 on the two rotating arms 71 will contact the surface of the tire. Further, the staff starts the tire balancing device 1 to make the tire The driving spindle of the balancing device 1 drives the tire to rotate. During the rotation of the tire, the bristles 73 on the two rotating arms 71 will continuously brush the surface of the tire. It is worth noting that the bristles 73 are hard bristles with a certain strength. Therefore, for loose stones stuck in the tire tread, the bristles 73 can brush them off the tire, avoiding the loose stones from being thrown out of the tire when the tire rotates at high speed in the later stage, thereby protecting the staff. For stones stuck tightly in the tire tread, although the bristles 73 cannot brush them off the tire, such stuck stones will not be thrown out during the rotation of the tire. Therefore, the function of the cleaning structure is not to completely clean the stones stuck in the tire, but to ensure safety during the inspection process and avoid injuries to the staff caused by stones thrown out of the tire.

[0103] When the tire cleaning is completed, the staff continues to step on the pedal 95 to make the lifting plate 92 continue to move downward. Since the two inclined surfaces are provided on the stopper 122, the lifting plate 92 can squeeze the inclined surfaces of the stopper 122 when it moves downward. When the stopper 122 is squeezed, it can move and retract into the groove 121. The movable characteristic of the stopper 122 can avoid the movement interference between the stopper 122 and the lifting plate 92. In addition, the elastic force applied by the second spring 123 on the stopper 122 is relatively small. When the lifting plate 92 moves up and resets, the thrust applied by the capsule 94 on the lifting plate 92 can easily overcome the elastic force applied by the second spring 123 on the stopper 122. This design can avoid the two stops 122 hindering the lifting plate 92 from moving up and resetting. In addition, when the two first springs 83 drive the two slide plugs 82 to reset, the two slide plugs 82 can return the liquid medium to the capsule 94 again. The entry of the liquid medium also helps the lifting plate 92 to reset smoothly.

[0104] When cleaning the tire, the tire is placed on two rollers 103. As the tire rotates, the two rollers 103 will also rotate, which causes the two rotating shafts 102 to rotate. When the two rotating shafts 102 rotate, one of the rotating shafts 102 can drive the shaft 112 to rotate, which causes the suction piece 113 to rotate. The suction piece 113 is provided with a plurality of axial flow blades, and the plurality of axial flow blades can perform a suction action when rotating. Therefore, when the suction piece 113 rotates, the two suction ports 74 on the two rotating arms 71 can absorb the dust generated during the tire cleaning process. The dust will enter the filter cartridge 116 under the suction action of the suction piece 113 and will eventually be intercepted by the filter element 117. This design can clean the dust generated during the tire cleaning process.

[0105] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.

A control method for a tire balancing machine, based on the tire balancing machine according to claim 8, characterized in that: The following steps are involved: Step 1: Tire installation and tightening a. Preparation: Ensure the scissor-type hydraulic lift is in the lowest position and the slide is away from the tire balancing equipment; b. Tire placement: The staff lifts the tire onto the fixed frame and places it between the two rollers and two rotating arms; c. Tire compression: The worker presses down on the pedal, squeezing the bladder through the lifting plate, causing the liquid medium to push the slide plug to move, which in turn drives the rotating arms to rotate synchronously and move closer to each other until the two compression blocks press the tire together, completing the tire compression and fixation; Step 2: Tire lifting and positioning a. Tire lifting: The staff uses the scissor-type hydraulic lifting device to lift the tire until it rises to a position facing the main drive shaft of the tire balancing equipment; b. Tire positioning: The staff pushes the fixed frame to drive the slide on the slide rail until the tire is placed on the driving spindle of the tire balancing equipment; c. Fixing the tire: The staff fixes the tire on the driving spindle of the tire balancing equipment to complete the tire installation; Step 3: Tire cleaning preparation a. Release the pedal: When the operator releases the pedal, the lifting plate moves upward and resets under the elastic force of the bladder itself and the two first springs. Simultaneously, the two rotating arms rotate synchronously and away from each other, separating the two pressing blocks from the tire. b. Adjust the position: The staff pulls the fixed frame to move the two rotating arms away from the tire balancing equipment in preparation for tire cleaning; Step 4: Tire cleaning a. Step on the pedal again: The staff member steps on the pedal again, causing the lifting plate to descend to a position where it contacts the two blocks. At this point, the bristles on the two rotating arms contact the tire surface. b. Start cleaning: The staff starts the tire balancing equipment to rotate the tire. At the same time, the bristles on the two rotating arms continuously brush the tire surface to remove stones and impurities on the tire; c. Dust collection: The suction piece rotates with the tire, and absorbs the dust generated during the cleaning process through the suction port. The dust enters the filter barrel and is intercepted by the filter element; Step 5: Cleaning and resetting a. Continue to step on the pedal: The staff continues to step on the pedal to make the lifting plate continue to move downward, squeezing the inclined surface of the stopper so that the stopper retracts into the groove to avoid movement interference; b. Reset operation: Release the pedal, the lifting plate moves up and resets under the thrust of the capsule, and the two slides reset under the elastic force of the first spring, returning the liquid medium back to the capsule; c. Arrange equipment: The staff will arrange the fixed frame and rotating arm parts to ensure that the equipment is in good condition and prepare for the next use.
