Description

Technical Field

[0001] The utility model relates to the technical field of tire changing machines, in particular to a tire changing machine for automobile disassembly. Background Art

[0002] A tire changer, also known as a tire changer or tire unloader, is a mechanical device specially used for removing and installing automobile tires. It plays an important role in automobile repair, maintenance or tire replacement. A tire changer is generally composed of a main workbench, a wheel clamp, a separation arm and a control pedal. The main workbench mainly plays the role of placing the tire and rotating it. The separation arm is on one side of the tire changer, and is mainly used to separate the tire from the wheel hub so that the tire removal can proceed smoothly. The foot pedal is a foot switch under the tire changer, which functions as a clockwise and counterclockwise rotation switch, a separation tightening switch, a wheel hub and tire separation switch, etc., so that the user can control the separation plate main workbench. The wheel hub clamp is an important component that cooperates with the main workbench to clamp the wheel hub tightly and stably. Due to the different wheel hub sizes of different vehicles, it is necessary to adjust the clamping stability range of the wheel hub clamp.

[0003] In the related art, during the use of the tire changing machine, a threaded lifting method is generally used to adjust the clamping stability range of the clamping disc on the clamp surface so that the clamping disc can meet the wheel hub clamping stability requirements for use.

The clamping plate 4 presses the tire hub against the top of the support frame 2 through the clamp screw 3. The staggered positioning mechanism includes a staggered groove 11, a downward groove 12 and a positioning groove 13. The staggered groove 11 is provided on both sides of the surface of the adjustment column 6. The inner side of the staggered groove 11 is connected to the outer side of the lifting groove 9. There are several staggered grooves 11, and the several staggered grooves 11 are distributed at equal distances. The downward groove 12 is provided on the outer side of the bottom of the inner wall of the staggered groove 11, and the positioning groove 13 is provided on the inner side of the bottom of the inner wall of the downward groove 12. When the lifting block 10 is used in conjunction with the lifting groove 9, the lifting block 10 is provided with space for staggered separation from the lifting groove 9, and for lifting and adjusting the positioning of the lifting block 10 to the adjustment column 6, thereby avoiding the situation where it is difficult to lift and position the adjustment column 6 when the lifting block 10 is used, thereby improving the convenience of positioning the adjustment column 6 by the lifting block 10.

[0033] Reference Figure 2-Figure 4 The top of the rotating seat 16 is embedded with a magnetic disk 17, and the top of the inner wall of the rotating groove 15 is embedded with a magnetic suction disk 18 that is magnetically connected to the magnetic disk 17. When the rotating seat 16 is used in conjunction with the stable seat 14, the stable seat 14 and the tightening disk 4 can be magnetically positioned by the rotating seat 16, so as to avoid the situation that the stable seat 14 is difficult to position when in use, thereby improving the positioning convenience of the stable seat 14.

The limiting block 23 is located at the bottom of the receiving groove 24, which can provide a downward accommodating space for the limiting block 23 when the limiting block 23 is used with the positioning post 20, avoiding the situation that the positioning post 20 is difficult to move into the slot 21 due to the position of the limiting block 23 when the positioning post 20 is in use, thereby improving the flexibility of the use of the limiting block 23.

[0036] Specifically, the working process or working principle of the tire changing machine for automobile disassembly is as follows: when in use, when the clamping disc 4 is lifted and lowered by the clamping screw 3 to meet the external tire changing hub and the support frame 2 to be tightly and stably pressed, the clamping disc 4 is held and rotated to match the screw groove inside the clamping disc 4, and the tight stability range of the clamping disc 4 can be adjusted. During this process, the clamping screw 3 directly observes the clamping disc 4 and prompts the connecting seat 8 to disengage from the connecting port 7. When the clamping disc 4 cannot meet the external tire changing hub and the support frame 2 to be tightly and stably pressed by the clamping screw 3, first hold the clamping disc 4 to match the internal screw groove and the clamping screw 3 to rise to the top of the clamping screw 3, and make the connecting seat 8 enter the inside of the connecting port 7, and then hold the positioning column 20 to drive the stabilizing seat 14 inward. Rotate. At this time, the rotating seat 16 rotates inside the rotating groove 15, and performs rotational connection work between the stable seat 14 and the tightening disk 4, and performs magnetic positioning work between the stable seat 14 and the tightening disk 4 through the magnetic disk 17 and the magnetic suction cup 18. During this process, the limit block 23 is in a state inside the limit opening 22, and performs limiting and stabilizing work between the positioning column 20 and the positioning hole 19. When the stable seat 14 is flipped to the top of the connecting seat 8 and the positioning hole 19 is aligned with the slot 21, the positioning column 20 is moved downward by hand into the slot 21, so that the stable seat 14 cooperates with the positioning column 20 and the slot 21, and performs plug-in positioning and blocking stabilization work between the connecting seat 8 and the tightening disk 4. At the same time, the limit block 23 follows the positioning column 20 into the accommodating groove 24 The part ensures the smoothness of the downward movement of the positioning column 20. Subsequently, according to the actual width of the tire hub outside, the handheld clamping plate 4 is used to cooperate with the connecting port 7 through the connecting seat 8 to drive the adjusting column 6 to move upward inside the adjusting groove 5 to adjust and expand the clamping range of the clamping plate 4. At this time, the lifting block 10 moves inside the lifting groove 9 to lift and connect the adjusting column 6 and the adjusting groove 5. During this process, a partial counterclockwise rotational force should be applied to the adjusting column 6. When the lifting block 10 moves inside the lifting groove 9 and is aligned with the staggered groove 11, affected by the counterclockwise rotational force of the adjusting column 6, the adjusting column 6 mobilizes the staggered groove 11 to move toward the lifting block 10, so that the lifting block 10 enters the staggered groove 11, and the lifting block 10 is connected to the lifting groove 9. When the lifting block 10 enters the staggered groove 11 and no counterclockwise rotation force can be applied, it means that the lifting block 10 is aligned with the lower groove 12. At this time, the holding plate 4 drives the adjusting column 6 to move upward, so that the lifting block 10 is separated from the staggered groove 11 and enters the lower groove 12. When the lifting port enters the lower groove 12 and the adjusting column 6 can no longer be pulled upward, it means that the lifting block 10 is aligned with the positioning groove 13. Then, the holding plate 4 drives the adjusting column 6 to rotate clockwise, so that the lifting block 10 enters the positioning groove 13 and performs staggered downward positioning between the adjusting column 6 and the adjusting groove 5, thereby ensuring the stability of the adjusting column 6 after adjustment, and ensuring that the tight stability range of the tight plate 4 can meet the tight positioning requirements of the tire hub outside.So that the user can use the clamping plate 4 to press the tire hub firmly on the top of the support frame 2 through the clamp screw 3 to perform the tire changing operation.

[0037] It should be noted that the tire changer body 1, support frame 2, clamp screw 3 and clamping plate 4 are all devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
