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 vehicle 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, the Chinese patent with publication number CN117870961A discloses a bias tire dynamic balancing machine, including a tire dynamic balancing machine body, a test control panel, a 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 scheme ensures that the bias tire is firmly installed on the shaft assembly by tightly holding the bias tire against the mounting abutment block and locking it with the locking handle. By using the tire dynamic balancing machine body and the tire fastening mechanism, it can ensure that the rotation speed of the bias tire is consistent with the rotation speed of the shaft assembly, avoiding errors caused by inconsistent rotation speeds. When the mounting abutment block rotates at high speed, the friction force on the bias tire can be increased by tightening the abutment block, which can prevent the bias tire from sliding or loosening when rotating at high speed. However, the above scheme still has the following shortcomings when actually used: 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 have a certain weight, manually lifting these tires will consume a lot of physical strength of the staff. Such operations for a long time are likely to cause 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 tires may fall off, which will not only damage the equipment but also cause harm to the staff.

[0015] A control method for a tire balancing machine comprises the following steps: Step 1: Tire installation and tightening a. Preparation: Make sure the scissor-type hydraulic lifting device 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 the tire between two rollers and two rotating arms; c. Compress the tire: The staff presses down on the pedal to squeeze the bladder through the lifting plate, so that the liquid medium pushes the sliding plug to move, and then drives the rotating arms to rotate synchronously and move closer to each other until the two pressing blocks press the tire together to complete the compression and fixation of the tire; Step 2: Tire lifting and positioning a.

[0016] The present invention has the following beneficial effects: 1. The automatic compression and fixation of the tire is achieved by driving the rotating arm and the pressing block through the squeezing of the bladder. There is no need to lift the tire directly manually, 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 the safety hazards such as falling and spraining that may occur during the lifting and handling of the tire by mechanized operation, effectively protecting the safety of the workers; 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 harm to the staff caused by the stones. This is the most important function of the cleaning structure, ensuring the safety during the detection process. In addition, the existence of the cleaning structure helps to keep the tire surface clean and reduce the interference of stones and other impurities on the tire balance detection results, thereby improving the accuracy and reliability of the detection; 3. The rotation of the air suction piece and the suction action of the axial flow blades can efficiently absorb the dust generated during the tire cleaning process to ensure a clean working environment. The design intercepts the dust through the filter element to avoid direct discharge of dust, which meets environmental protection requirements. At the same time, since the air suction piece is driven by the rotation of the tire, no additional energy consumption is required, which reflects the characteristics of energy saving.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] 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 the innovative parts 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 on the lifting part of the scissor-type hydraulic lifting device 2; a slide rail 4, which is fixed on the top surface of the mounting plate 3; a slide seat 5, which is slidably assembled on the slide rail 4; a fixing frame 6, which is fixed on the top surface of the slide seat 5; The tire balancing machine also includes a clamping structure, which is arranged on the fixing frame 6. The clamping structure includes: two rotating arms 71, which are both rotatably mounted on the fixing frame 6, and the two rotating arms 71 are both arc-shaped structures. The interior of each rotating arm 71 is a hollow structure, and the internal spaces of the two rotating arms 71 are connected through a hose; two clamping blocks 72, which are respectively fixed to one end of the two rotating arms 71 away from the fixing frame 6; a plurality of bristles 73, which are respectively bonded to the opposite sides of the two rotating arms 71; and a plurality of suction ports 74, which are respectively opened on the opposite sides of the two rotating arms 71; 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 structures. The connecting structures include: 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 slidably 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 connected to the inner surface of the sealing cylinder 81, and the other end is connected to the sliding plug 82; One end of the connecting rod 84 located outside the sealing cylinder 81 is rotatably connected, and the other end is rotatably mounted on the rotating arm 71. When the liquid medium enters the sealing cylinder 81, the liquid medium can push the sliding plug 82 to move, and the sliding plug 82 can drive the connecting rod 84 to move when it moves. Since the sealing cylinder 81 is rotatably mounted on the fixing 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. 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 on the tire balancing device 1; a lifting plate 92, which is slidably arranged inside the mounting box 91; two guide rods 93, which are both 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 tubes 8 1 is connected, and liquid medium is accumulated in the bladder 94; a pedal 95 is fixed on the side of the lifting plate 92; a slideway 96 is provided on the side of the mounting box 91, and the pedal 95 slides in the slideway 96. When the lifting plate 92 moves downward, the bladder 94 can be squeezed. When the bladder 94 is squeezed, the liquid medium inside it will enter the inside 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 press the tire together, and the tire is pressed and fixed by the two pressing blocks 72; Two blocking structures are both arranged on the inner surface of the installation box 91, and the blocking structures include: 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 stoppers 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 inclined surface of the stopper 122 can be squeezed when the lifting plate 92 moves downward, and the stopper 122 can move when squeezed and retract into the groove 121. The movable characteristic of the stopper 122 can avoid the situation of motion interference between the stopper 122 and the lifting plate 92; 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 arranged 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 air suction cylinder 111, one end of which is fixedly connected to the rotating shaft 102; an air suction member 113, fixed to the end of the shaft 112 away from the rotating shaft 102, the air suction member 113 includes a sleeve and a plurality of axial flow blades, the sleeve is fixedly sleeved on the shaft 112, 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; an air guide cover 114, fixed to the end of the air suction cylinder 111 away from the mounting frame 101, and communicated with the interior of the air suction cylinder 111; an air extraction pipe 115 , one end is connected with 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 with 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 with 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 with the rotation of the tire, the two rollers 103 will also rotate accordingly, 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 piece 113 rotate. A plurality of axial flow blades are provided in the suction piece 113, and a plurality of axial flow blades can perform an exhaust action when they rotate. Therefore, when the suction piece 113 rotates, the two suction ports 74 on the two rotating arms 71 can absorb 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 play a role in cleaning the dust generated during the tire cleaning process.

[0021] The specific working principle of the present invention is as follows: 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 seat 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 to drive 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 through the two connecting pipes respectively. 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 plate 85. One end of the connecting rod 84 is rotatably connected to the rotating arm 71, so when the sliding 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 clamping blocks 72 jointly press the tire, and the tire is clamped and fixed by the two clamping blocks 72. Then, the staff raises the tire through the scissor-type hydraulic lifting device 2 until the tire rises to a position facing the driving spindle of the tire balancing device 1. Further, the staff pushes the fixing frame 6, and the fixing frame 6 can drive the slide 5 to move when it moves, so that the slide 5 slides on the slide rail 4 until the tire is set on the driving spindle of the tire balancing device 1. Finally, the staff fixes the tire on the driving spindle 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 to the spindle of the tire balancing device 1, which can reduce the physical consumption of the staff and avoid the tire falling during the lifting process, thereby ensuring the safety of the operation. After the tire is fixed to the driving spindle of the tire balancing device 1, the staff releases the pedal 95, so that the lifting plate 92 moves up and resets under the elastic force of the bag 94 itself, and at the same time, the two slide plugs 82 are reset in cooperation 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 synchronously rotated and moved away from each other, so that the two clamping 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 realizing the separation operation between the tire and the two rotating arms 71. 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 installation box 91, the two rotating arms 71 will separate from the tire. Then the staff presses the pedal 95 downward again to move the lifting plate 92 downward. The lifting plate 92 will contact with 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 at a position in contact with the two blocks 122. At this time, the two clamping 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 tight stones stuck in the tire tread, the bristles 73 cannot brush them off the tire, but such tight stones will not be thrown out during the rotation of the tire. Therefore, the role of the cleaning structure is not to clean the stones stuck in the tire comprehensively, but to ensure the safety during the detection process, avoiding the stones thrown out of the tire from causing harm to the staff. After the tire cleaning is completed, the staff continues to step on the pedal 95 downward 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 surface of the stopper 122 when it moves downward. The stopper 122 can move and retract into the groove 121 when it is squeezed. 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 to the stopper 122 is relatively small. When the lifting plate 92 moves up and resets, the thrust applied by the capsule 94 to the lifting plate 92 can easily overcome the elastic force applied by the second spring 123 to 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. 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 they rotate. 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.
