Description

Technical Field

[0001] This utility model relates to the field of tire disassembly and assembly equipment technology, and in particular to a tire disassembly and assembly machine. Background Technology

[0002] In the automotive repair and tire manufacturing industry, tire changers are core equipment for efficient tire loading and unloading. Their structural stability and service life directly affect operational efficiency and maintenance costs. Currently, most mainstream tire changers on the market are equipped with a robotic arm for performing tire gripping, positioning, and loading / unloading operations. This robotic arm is typically connected to the upper end of a rear-mounted arm via a sliding connection to allow for horizontal position adjustment. Simultaneously, the lower end of the rear-mounted arm is rotatably connected to the equipment base, allowing the rear-mounted arm to swing around the base's pivot point, thereby adjusting the robotic arm's working angle to adapt to different loading / unloading needs.

[0003] However, existing tire changers have the following problems during long-term use: (1) When the back-tilting arm rotates around the base to adjust the working angle, the contact area between the lower end of the back-tilting arm and the base adopts a rigid contact design. When the back-tilting arm swings to the position and contacts the base, the rigid contact will generate an instantaneous impact load, which will cause deformation and wear at the lower end of the back-tilting arm or the contact part of the base, severely shortening the service life of the equipment. At the same time, the vibration generated by the impact may also be transmitted to the robotic arm, affecting tire installation and removal. (2) If the assembly gap between the robotic arm and the rear tilting arm is too large, the excessive gap will cause the robotic arm to shake unexpectedly during operation after the robotic arm slides along the rear tilting arm to the target working position. Especially in the force operation of disassembling or installing tires, the shaking will directly destroy the relative positioning stability of the robotic arm and the tire, which will not only increase the difficulty of operation and reduce the efficiency of operation, but may also cause tire or rim scratches due to positioning deviation, and even cause safety hazards.

[0004] Therefore, there is an urgent need to design a tire changer to improve the operational stability and durability of the tire changer. Utility Model Content

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] The purpose of this invention is to provide a tire changer / installer to solve the problems existing in the prior art, extend its service life, and improve operational stability.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1-7As shown, this embodiment provides a tire changer, including a base 3, a rear tilting arm 1, a push-pull arm 5, a sliding arm 4, and a robotic arm 2. The lower end of the rear tilting arm 1 is rotatably connected to the upper end of the base 3, and a buffer element is provided between the lower side wall of the rear tilting arm 1 and the upper side wall of the base 3. When the rear tilting arm 1 is rotated to its final position, the lower side wall of the rear tilting arm 1 can act on the upper inner side wall of the base 3 through the buffer element. The buffer element buffers the impact load when the rear tilting arm 1 rotates, thereby avoiding direct contact between the lower side wall of the rear tilting arm 1 and the upper inner side wall of the base 3 when the rear tilting arm 1 is rotated to its final position, which would otherwise cause the rear tilting arm to be damaged. 1. Damage to the equipment base 3, thereby improving the service life of the tire changer. One end of the mechanical arm 2 is connected to one end of the push-pull arm 5, and the other end of the push-pull arm 5 is slidably connected to the sliding arm 4. The sliding arm 4 is connected to the upper end of the rear tilting arm 1. Through the cooperation of the push-pull arm 5 and the sliding arm 4, the horizontal extension and retraction of the mechanical arm 2 can be realized. A fastening element 6 is provided between the push-pull arm 5 and the sliding arm 4. The fastening element 6 is used to fasten the push-pull arm 5 and the sliding arm 4 after the push-pull arm 5 slides into place. Then, after the mechanical arm 2 extends and retracts into place, the push-pull arm 5 is fixed by the fastening element 6 to prevent the push-pull arm 5 from shaking and affecting the operation of the mechanical arm 2, thereby improving the stability of the operation.

[0023] Specifically, the upper end of the equipment base 3 is provided with a base mounting groove 31, which is used to dock with the lower end of the rear tilting arm 1. The lower end of the rear tilting arm 1 is rotatably connected to the base mounting groove 31. The buffer element is located between the outer wall of the lower end of the rear tilting arm 1 and the inner wall of the base mounting groove 31, thereby buffering the contact area between the outer wall of the lower end of the rear tilting arm 1 and the inner wall of the base mounting groove 31.

[0024] The buffer element includes a first buffer element 8. A limiting bottom rib 11 is installed on one side of the lower end of the rear tilt arm 1. The limiting bottom rib 11 is used to limit the rear tilt arm 1 to the inner wall of the base mounting groove 31 when it rotates to a vertical position. The first buffer element 8 is located between the limiting bottom rib 11 on the side away from the tire and the inner wall of the base mounting groove 31. Thus, when the rear tilt arm 1 rotates back to a vertical position, the limiting bottom rib 11 is limited by the base mounting groove 31, and the first buffer element 8 provides buffering to avoid excessive instantaneous load between the limiting bottom rib 11 and the base mounting groove 31, which could cause structural damage.

[0025] The first buffer element 8 is installed on the side of the limiting bottom rib 11 away from the tire; there are two first buffer elements 8, which are arranged in a horizontal direction. Those skilled in the art can also make adaptive adjustments to the number and setting position of the first buffer elements 8 according to actual needs.

[0026] The buffer element also includes a second buffer element 9. A limiting angle plate 12 is also installed at the lower end of the tilting arm 1. The limiting angle plate 12 is located on the side of the limiting bottom rib 11 near the tire. A base rib groove 32 is also provided in the base mounting groove 31. The limiting angle plate 12 is used to limit the tilting arm 1 to the outer wall of the base rib groove 32 when it rotates to the tilting limit position. The second buffer element 9 is located between the limiting angle plate 12 on the side near the tire and the outer wall of the base rib groove 32. Thus, when the tilting arm 1 rotates to the tilting limit position, the limiting angle plate 12 is limited by the base rib groove 32, and the second buffer element 9 provides buffering to avoid excessive instantaneous load between the limiting angle plate 12 and the base rib groove 32, which could cause structural damage.

[0027] The second buffer element 9 is installed on the outer wall of the base rib groove 32. Those skilled in the art can also make adaptive adjustments to its specific position according to actual needs.

[0028] As a preferred embodiment, the buffer element is a buffer pad, and the buffer pad can be designed to be detachable, so that it is easy to replace when the buffer pad ages.

[0029] An adjustment element 7 is provided on each of the two opposite side walls of the base mounting groove 31. The two adjustment elements 7 are used to act on the lower part of the two opposite side walls of the tilt arm 1, thereby limiting the lower end of the tilt arm 1. The adjustment element 7 includes an adjustment knob 71 and an adjustment limit nut 72. One end of the adjustment limit nut 72 can pass through the side wall of the base mounting groove 31 and be connected to the adjustment limit nut 72. The adjustment limit nut 72 is located between the inner side wall of the base mounting groove 31 and the outer side wall of the tilt arm 1. The adjustment knob 71 is used to adjust the gap between the adjustment limit nut 72 and the outer side wall of the tilt arm 1. In actual use, the adjustment knob 71 can be used to maintain a minimum gap between the end of the adjustment limit nut 72 and the outer side wall of the tilt arm 1. For example, the gap between the two is not greater than 1mm. This gap can ensure that the tilt arm 1 can rotate smoothly while avoiding large-scale rotation of the tilt arm 1, thus improving working stability.

[0030] There are two fastening elements 6, which are respectively set on the two opposite sides of the push-pull arm 5. The fastening element 6 includes a fastening knob 61, a fastening limit nut 62, and a tightening post 63. The fastening limit nuts 62 of the two fastening elements 6 are respectively set on the two opposite side walls of the slide arm 4, and the tightening posts 63 of the two fastening elements 6 are respectively installed on the two opposite side walls of the push-pull arm 5. One end of the fastening knob 61 can pass through the fastening limit nut 62 and be tightened against the tightening post 63, and the fastening knob 61 is threadedly connected to the fastening limit nut 62. In use, the push-pull arm 5 slides within the sliding arm 4 to the desired position. When the horizontal position of the robotic arm 2 needs to be fixed, the fastening knob 61 is turned to rotate relative to the fastening limit nut 62. While rotating, the fastening knob 61 also gradually moves towards the top clamping post 63 until the fastening knob 61 contacts and clamps against the top clamping post 63. Through the cooperation of the two fastening elements 6, the push-pull arm 5 can be clamped, thus fixing its position. When the horizontal position of the robotic arm 2 needs to be adjusted, the fastening knob 61 is first loosened to rotate relative to the fastening limit nut 62. While rotating, the fastening knob 61 also gradually moves away from the top clamping post 63. At this time, the fastening knob 61 disengages from the top clamping post 63, and the push-pull arm 5 can reciprocate within the sliding arm 4.

[0031] The clamping post 63 is made of wear-resistant material, such as copper alloy. Those skilled in the art can make adaptive adjustments to the specific material selection according to actual needs.

The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model.
