Description

Technical Field

[0001] The utility model relates to the technical field of dynamic balancing machines, in particular to a lifting tooling for a dynamic balancing machine. Background Art

[0002] A dynamic balancing machine is used to measure the magnitude and position of the unbalance of a rotating object (rotor). It is mainly used to measure the balance coefficient of a tire, find the unbalanced position, and cooperate with a counterweight patch to perform a dynamic balancing operation on an automotive tire. A dynamic balancing machine usually cooperates with a lifting tooling to lift the automotive tire so as to facilitate the installation of the tire at the detection position of the dynamic balancing machine.

[0003] However, in the prior art, vibrations occur during the rising process of the lifting plate, which may cause the tire on the lifting plate to shift, and it is easy for the tire to fall down, posing a safety hazard to the staff. Moreover, during the installation process of the tire, auxiliary positioning of the tire is still required to prevent it from shaking, and the installation operation is inconvenient.

Start the motor installed on the positioning plate to drive the lead screw to rotate, and the threaded block drives the lifting plate to rise synchronously to the installation position, and install the tire on the dynamic balancing machine.

[0005] However, in the prior art, during the installation process of the tire, a guiding structure for centering the tire is lacking. As a result, when the tire is installed, its surface may collide with the installation position of the dynamic balancing machine due to misalignment of the center positioning, which affects the quality of the tire, and it is not convenient to quickly install the tire due to misalignment of the center positioning.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1 - 5 , the present invention provides a technical solution:

[0028] Embodiment 1:

[0029] A lifting tooling for a dynamic balancing machine includes a support leg 1. The top of the support leg 1 is connected with a lifting structure. The middle part on the right side of the lifting structure is connected with a pushing structure. The clamping structure is arranged on the left side of the lifting structure.

[0030] The lifting structure includes a lifting unit and an installation and limiting unit. The lifting unit includes an asynchronous motor 106. The output end of the asynchronous motor 106 is connected with a transmission part 107. The middle part of the outer surface of the transmission part 107 is connected with a connecting block 109. The left side of the connecting block 109 is connected with a lifting plate 104. The middle part near the top on the left side of the lifting plate 104 is provided with a lifting rod 105. The installation and limiting unit includes a workbench 101. A bearing 108 is installed in the middle of the top surface of the workbench 101. Guide rails 102 are installed at one end near the front and the back of the middle part of the top surface of the workbench 101. Limit strips 103 are installed in the middle of the side close to each other of the two guide rails 102.

[0031] The bottom surface of the workbench 101 is fixedly connected with the top end of the support leg 1. The asynchronous motor 106 is detachably connected with the middle part of the bottom surface of the workbench 101. The sides close to each other of the two limit strips 103 are fixedly connected with the front and the back of the lifting plate 104. The inside of the bearing 108 is connected with the outer surface of the transmission part 107 near the bottom end without threads.

[0032] The pushing structure includes an electric push rod 201. The output end of the electric push rod 201 is connected to a pushing plate 202. In the middle of the left side of the pushing plate 202, a sliding rod 203 is fixedly connected. At the left end of the sliding rod 203, a pushing block 204 is fixedly installed. The electric push rod 201 is detachably installed near the top on the right side of the lifting plate 104. The outer surface of the sliding rod 203 is slidably connected to the inner wall of an arc-shaped through hole opened in the middle near the top on the right side of the lifting plate 104, and the outer surface of the sliding rod 203 is slidably connected to the outer surface of the lifting rod 105.

[0033] Through the settings of the lifting structure and the pushing structure, when the asynchronous motor 106 is started to drive the transmission member 107 to transmit, the lifting plate 104 and the limiting strip 103 are driven to rise along the guide rail 102 via the connecting block 109, and the lifting rod 105 is used to connect and guide the installation part of the dynamic balancer, which is convenient for central positioning and guiding the detection and installation of the tire, making the installation of the tire more accurate. At the same time, the electric push rod 201 contracts to drive the pushing plate 202, the sliding rod 203 and the pushing block 204 to push the tire, which is convenient for the installation and detection of the tire.

[0034] When lifting and installing the tire, after placing the tire on the outer surface of the lifting rod 105, the asynchronous motor 106 is started to drive the transmission member 107 to transmit. The output end of the asynchronous motor 106 drives the threaded rod to rotate. By using the threaded connection between the threaded rod and the threaded cylinder, and the fixed connection between the threaded cylinder and the connecting block 109, the connecting block 109 is used to drive the lifting plate 104 and the lifting rod 105 to rise. At the same time, when the lifting plate 104 rises, the limiting strip 103 slides inside the chute opened in the guide rail 102 to maintain the stability during the rising process. After the central positioning and docking of the lifting rod 105 with the installation part of the dynamic balancer, the electric push rod 201 is started to contract, driving the pushing plate 202 and the sliding rod 203 to slide to the left. By using the sliding of the pushing plate 202 inside the arc-shaped hole opened on the right side of the lifting plate 104 and on the outer surface of the lifting rod 105, the pushing block 204 is used to push the tire, and the tire is installed at the detection position of the dynamic balancer under the guidance of the lifting rod 105.

[0035] Embodiment 2:

[0036] On the basis of Embodiment 1, the clamping structure includes a guiding block 301. Inside the guiding block 301, a sliding block 302 is slidably connected. At the top of the sliding block 302, a clamping block 303 is fixedly installed. Inside the sliding block 302, a bidirectional threaded rod 304 is connected. At one end of the front and back of the outer surface of the bidirectional threaded rod 304, a fixing member 305 is connected. At one end of the front of the bidirectional threaded rod 304, a turntable 3'06 is fixedly installed. The bottom surface of the guiding block 301 is fixedly connected to the middle left end of the top surface of the workbench 101. The fixing member 305 is fixedly connected to the front and back left ends of the workbench 101. The two sliding blocks 302 are connected to the outer surface of the bidirectional threaded rod 304 near one end of the front and back.

[0037] Through the setting of the clamping structure, rotating the turntable 306 drives the bidirectional threaded rod 304 to rotate. By utilizing the threaded connection between the bidirectional threaded rod 304 and the slider 302, the clamping block 303 can better clamp and fix the tire, and can clamp and fix it more flexibly when facing tires of different sizes.

[0038] When clamping the tire stably, place the tire at the middle of the side where the two clamping blocks 303 approach each other. Then rotate the turntable 306 to drive the bidirectional threaded rod 304 to rotate. By utilizing the double-thread formed on the outer surface of the bidirectional threaded rod 304 and the threaded connection between the bidirectional threaded rod 304 and the slider 302, the slider 302 can slide closer to or away from each other along the dovetail groove formed in the middle of the top surface of the guide block 301, thereby driving the two clamping blocks 303 to approach each other. Thus, the arc surfaces of the two clamping blocks 303 are used to clamp and stabilize the tire, so as to facilitate the stability during the lifting operation of the tire. Moreover, the adjustment of the distance between the clamping blocks 303 facilitates clamping and stabilizing tires of various sizes.
