Description

Technical Field

[0001] This utility model belongs to the field of material handling device technology, and in particular relates to a tire handling device for a tire changer. Background Technology

[0002] Tire changers are mechanical devices specifically designed for changing tires on automobiles, motorcycles, heavy trucks, and other vehicles. They mainly consist of a main workbench, a separating wall, an inflation / deflation device, a lubrication system, and a power interface. Based on power type, they can be divided into pneumatic and hydraulic tire changers; based on size, they can be divided into small vertical tire changers and large horizontal tire changers. Pneumatic tire changers use compressed air to drive the separating arm, turntable, and other components to complete the action, while hydraulic tire changers use hydraulic cylinders to push the support claws and other structures, providing greater force. Tire changers replace traditional manual tire prying, achieving fast and precise tire removal and installation, avoiding tire damage, and are widely used in auto repair shops, 4S stores, tire shops, and other similar locations.

[0003] In tire disassembly and repair operations, tires often need to be moved, repositioned, and secured. Existing tire changers mostly rely on external clamps to hold the tire from the side. As an elastic rubber product, tires are prone to elastic deformation and inward contraction when subjected to external radial clamping force, leading to loosening of the clamping points and insecure fixation, affecting operational safety and stability. In addition, existing clamps are usually designed for specific tire sizes, resulting in poor compatibility with tires of various sizes. Operators often need to frequently change clamps. Furthermore, when inspecting, grinding, or repairing tires, it is often necessary to flip the tire to operate on different sides. Existing tire changers usually require the tire to be removed from the fixing device first, manually flipped, and then repositioned and fixed, causing interruptions in the operation process and affecting overall work efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a tire handling device for a tire changer in order to solve the problems of unstable external clamping, poor adaptability of existing tire changer machines, and cumbersome tire flipping operation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a tire handling device for a tire changer, comprising a mounting plate, two rotating seats on one outer wall of the mounting plate, a rotating mechanism, the rotating mechanism including a rotating plate disposed on one side of the mounting plate, rotating rods rotatably connected to both outer walls of the rotating plate, one end of the rotating rods being rotatably connected to the rotating seats, the rotating plate being configured to rotate about one end of the rotating rods as an axis and lift the tire, and a fixing mechanism, the fixing mechanism including a telescopic shaft passing through the outer wall of the rotating plate, multiple support blocks disposed on the outside of one end of the telescopic shaft, the support blocks being configured to surround the axis of the telescopic shaft, and the movement of the support blocks being controlled by the telescopic extension and retraction of the telescopic shaft.

[0006] Preferably, the mounting plate has two limiting grooves at its bottom, a lead screw is rotatably connected inside the limiting groove, and a movable seat is provided outside the lead screw. One side of the movable seat is rotatably connected to one side of the rotating plate through a column.

[0007] Preferably, a drive wheel is rotatably connected to one side of the outer wall of the mounting plate, a driven wheel is connected to one end of the lead screw, a chain is connected between the drive wheel and the driven wheel, a motor is installed on one side of the outer wall of the mounting plate, and the output end of the motor is connected to one side of the drive wheel.

[0008] Preferably, a fixed plate is slidably connected to the outer wall of the telescopic shaft, the fixed plate is connected to one side of the rotating plate, an electric push rod is installed on one side of the rotating plate, and the telescopic part of the electric push rod is connected to one end of the telescopic rod.

[0009] Preferably, the outer wall of the fixed plate is rotatably connected to a plurality of first connecting rods, one end of which is rotatably connected to a linkage rod, the middle of which is rotatably connected to a protrusion of the moving plate, the outer wall of the protrusion of the moving plate is rotatably connected to a second connecting rod, the second connecting rod is rotatably connected to a mounting rod, and the corresponding positions on the outer wall of the mounting rod are rotatably connected to one end of the linkage rod and one end of the second connecting rod, respectively.

[0010] Preferably, one end of the mounting rod is connected to the support block, and the outer wall of the support block has a groove, and the groove has multiple anti-slip grooves.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0012] 1. In this utility model, by setting a fixing mechanism, the support block unfolds outward to fix the tire from the inside, preventing the tire from contracting inward due to elasticity when fixing from the outside, thus ensuring the stability of the fixation. At the same time, the unfolding range of the support block of the fixing mechanism is controllable, and the fixing range can be dynamically adjusted according to different tire sizes, improving the adaptability of the device.

[0013] 2. In this utility model, by setting a rotating mechanism, the tire can be directly flipped after the fixing mechanism fixes the tire, which makes it convenient for workers to operate on different sides of the tire. When it is necessary to change the direction of the tire, there is no need to remove the tire from the clamp and then install it, which improves the smoothness of operation and improves work efficiency.

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5This utility model provides a technical solution: a tire handling device for a tire changer, including a mounting plate 1, two rotating seats 3 on one outer wall of the mounting plate 1, a rotating mechanism 4, the rotating mechanism 4 including a rotating plate 401 on one side of the mounting plate 1, rotating rods 402 rotatably connected to both outer walls of the rotating plate 401, one end of the rotating rods 402 being rotatably connected to the rotating seats 3, the rotating plate 401 being configured to rotate about one end of the rotating rods 402 as an axis and lift the tire, and a fixing mechanism 5, the fixing mechanism 5 including a telescopic shaft 501 passing through the outer wall of the rotating plate 401, a plurality of support blocks 508 being provided on the outside of one end of the telescopic shaft 501, the support blocks 508 being configured to surround the axis of the telescopic shaft 501, and the movement of the support blocks 508 being controlled by the telescopic shaft 501.

[0022] Two limiting grooves 2 are provided at the bottom of the mounting plate 1. A lead screw 403 is rotatably connected inside the limiting groove 2. A movable seat 404 is provided outside the lead screw 403. One side of the movable seat 404 is rotatably connected to one side of the rotating plate 401 through a column.

[0023] A drive wheel 405 is rotatably connected to one side of the outer wall of the mounting plate 1. One end of the lead screw 403 is connected to the driven wheel 406. A chain 407 is connected between the drive wheel 405 and the driven wheel 406. A motor 408 is mounted on one side of the outer wall of the mounting plate 1. The output end of the motor 408 is connected to one side of the drive wheel 405.

[0024] Specifically, the external thread on the outer wall of the lead screw 403 meshes with the internal thread on the inner wall of the moving seat 404. The moving seat 404 can move along the direction of the lead screw 403. The outer wall of the moving seat 404 is slidably connected to the inner wall of the limiting groove 2. The motor 408 drives the drive wheel 405 to rotate through its output end. The drive wheel 405 drives the driven wheel 406 to rotate through the chain 407. The lead screw 403 rotates with the driven wheel 406. The cross-sectional shape of the rotating rod 402 is L-shaped. The longer end of the L-shaped rotating rod 402 has a stroke groove on its outer wall. The side wall of the rotating plate 401 is slidably connected to the stroke groove through a column. The shorter end of the L-shaped rotating rod 402 is rotatably connected to the rotating seat 3. When the moving seat 404 moves closer to the motor 408 along the direction of the lead screw 403, the rotating plate 401 rotates around the side wall column as the axis. The end of the rotating plate 401 rotatably connected to the moving seat 404 is lifted upward. The side wall column of the rotating plate 401 slides from one end of the stroke groove to the other end of the stroke groove. The longer end of the L-shaped rotating rod 402 rotates away from the mounting plate 1 around the rotating seat 3 as the axis, so that the rotating plate 401 changes from vertical to horizontal. The rotating plate 401 drives the fixed mechanism 5 to move, so that the fixed mechanism 5 rotates 90 degrees.

[0025] It should be noted that the selection of motor 408 and control unit in the above description should be selected as needed. This part is well-known technology in the field and will not be elaborated here.

[0026] It should be noted that, in the above description, the lead screw 403 and the moving seat 404 constitute a lead screw structure. The lead screw is a precision transmission element that converts rotary motion into linear motion or vice versa. Its core function is to convert rotary motion into linear motion. Through the thread structure and rolling friction, it achieves high-precision and high-efficiency linear transmission. This part is a well-known technology in the field and will not be described in detail here.

[0027] It should be noted that, as described above, the drive wheel 405, driven wheel 406, and chain 407 constitute the sprocket and chain structure 407. The structures transmit motion and power through meshing. The chain drive has no elastic slippage and can maintain a stable transmission ratio. This part is well-known technology in the field and will not be described in detail here.

[0028] A fixed plate 502 is slidably connected to the outer wall of the telescopic shaft 501. The fixed plate 502 is connected to one side of the rotating plate 401. An electric push rod 510 is installed on one side of the rotating plate 401. The telescopic part of the electric push rod 510 is connected to one end of the telescopic rod.

[0029] Multiple first connecting rods 504 are rotatably connected to the outer wall of the fixed plate 502. One end of the first connecting rod 504 is rotatably connected to a linkage rod 505. The middle part of the linkage rod 505 is rotatably connected to the protrusion of the moving plate 503. A second connecting rod 506 is rotatably connected to the outer wall of the protrusion of the moving plate 503. An installation rod 507 is rotatably connected to the second connecting rod 506. The corresponding positions on the outer wall of the installation rod 507 are rotatably connected to one end of the linkage rod 505 and one end of the second connecting rod 506, respectively.

[0030] One end of the mounting rod 507 is connected to the support block 508. The outer wall of the support block 508 has a groove, and multiple anti-slip grooves 509 are provided in the groove.

[0031] Specifically, the linkage 505 has an L-shaped cross-section. A through hole is formed on the outer wall of the movable plate 503, and the telescopic shaft 501 passes through this hole. The electric push rod 510 drives the telescopic shaft 501 to move via the telescopic part. One side of the outer wall of the fixed plate 502 is connected to one side of the outer wall of the rotating plate 401. The telescopic shaft 501 extends relative to the fixed plate 502. The inner wall of the movable plate 503 is fixedly connected to the outer wall of the telescopic shaft 501. The telescopic shaft 501 drives the movable plate 503 to move away from the fixed plate 502. When the movable plate 503 moves away from the fixed plate 502, the first connecting rod 504 rotates around the protrusion of the fixed plate 502. The other ends of the four first connecting rods 504 approach each other and drive the shorter L-shaped end of the linkage 505 to rotate and approach each other. The L-shaped corner is the axis of rotation. The longer end of the L-shaped linkage 505 is lifted upwards and drives the second connecting rod 506 to rotate around the central connection position of the protrusion of the moving plate 503. The ends of the second connecting rod 506 and the mounting rod 507 that are rotatably connected are moved away from each other. The longer end of the L-shaped linkage 505 and the end of the second connecting rod 506 that is away from the moving plate 503 together drive the mounting rod 507 to move, so that the four mounting rods 507 are moved away from each other. The mounting rod 507 is connected to the support block 508 by a snap-fit. The mounting rod 507 drives the support block 508 to move. The fixing mechanism 5 unfolds so that the outer wall of the support block 508 contacts the inner wall of the tire. The anti-slip groove 509 on the outer wall of the support block 508 increases the friction between the outer wall of the support block 508 and the inner wall of the tire, making the fixation more stable.

[0032] It should be further explained that the buckle mentioned above is a device in the field of mechanical engineering that connects parts through locking components. It uses elastic deformation and friction mechanism to fix the parts. This part is a well-known technology in the field and will not be elaborated here.

[0033] It should be noted that the electric actuator 510 described above is a new type of linear actuator composed of a motor, an actuator, and a control device. It is an electric drive device that converts the rotational motion of the motor into the linear reciprocating motion of the actuator. This part is well-known technology in the field and will not be described in detail here.

[0034] Working principle: In use, the operator inserts the fixing mechanism 5 into the tire ring. Then, the operator starts the electric push rod 510, which pushes the telescopic shaft 501 out through the telescopic part. The moving plate 503 moves with the telescopic shaft 501. When the moving plate 503 moves away from the fixing plate 502, it drives the four support blocks 508 to unfold outward, so that the outer wall of the support block 508 fits tightly with the inner wall of the tire ring. Then, the operator starts the motor 408 to rotate the rotating plate 401 90 degrees. The rotating plate 401 drives the fixing mechanism 5 to rotate 90 degrees as a whole, so that the tire changes from being perpendicular to the horizontal plane to being horizontal to the horizontal plane. Then, the operator starts the tire changing machine to perform the operation.
