Detailed implementation manners

[0019] The following is only the preferred embodiment of the present utility model, and does not limit the protection scope of the present utility model accordingly.

[0020] Embodiment 1

[0021] A tire expanding and gripping device for vehicle maintenance, as Figures 1 - 3 shown, includes a workbench 1, on which a drive assembly 2 is installed. The drive assembly 2 includes a drive motor and a lead screw. A drive motor is installed at the front of the workbench 1, and a lead screw is connected to the output shaft of the drive motor. A first tire expanding assembly 3 is installed on the lead screw. The first tire expanding assembly 3 is located at the upper front part of the workbench 1. The first tire expanding assembly 3 includes a first connecting seat 31, and the first connecting seat 31 is threadedly connected to the lead screw. A first tire expanding plate 32 is slidably connected to the first connecting seat 31. A first locking member 33 is rotatably connected to the first connecting seat 31, and the first locking member 33 is threadedly connected to the first tire expanding plate 32. A first roller 34 is rotatably connected to the lower left side of the first connecting seat 31. A second tire expanding assembly 4 is installed at the upper rear part of the workbench 1. The second tire expanding assembly 4 includes a second connecting seat 41. The second connecting seat 41 is installed at the upper rear part of the workbench 1. A second tire expanding plate 42 is slidably connected to the second connecting seat 41. A second locking member 43 is rotatably connected to the second connecting seat 41, and the second locking member 43 is threadedly connected to the second tire expanding plate 42. A placing plate 5 is arranged on the workbench 1. The placing plate 5 is located between the first tire expanding assembly 3 and the second tire expanding assembly 4. A plurality of conveying rollers are rotatably connected to the placing plate 5. The placing plate 5 is of an arc-shaped structure. A tire 6 is placed on the placing plate 5. A protection mechanism 7 is arranged on the first connecting seat 31, and a protection mechanism 7 is also arranged on the second connecting seat 41.

[0022] As Figures 1 - 3As shown in the figure, the protection mechanism 7 includes first connecting plates 71. The left and right parts of the first connecting seat 31 are both equipped with first connecting plates 71, and the left and right parts of the second connecting seat 41 are also both equipped with first connecting plates 71. Two dampers 72 are connected to each of the first connecting plates 71. A buffer spring 73 is connected inside each damper 72, and a rubber pad 74 is connected between two adjacent dampers 72.

[0023] It should be noted that in automobile maintenance, when the tire 6 needs to be disassembled or installed from the wheel hub, an expanding machine is usually used to complete the tire expanding operation. First, the driving motor is started. The output shaft of the driving motor rotates to drive the screw rod to rotate. Under the guiding action of the first roller 34, the first connecting seat 31 is driven to move. The first connecting seat 31 moves forward to create a placement space for the tire 6. Then, the tire 6 is placed on the placement plate 5. The arc-shaped structure of the placement plate 5 can better fit the surface of the tire 6. Then, the second tire expanding plate 42 is installed at an appropriate height according to the height of the tire 6 and locked and fixed by the second locking member 43. The second tire expanding plate 42 clamps the rear part inside the tire 6. Then, the driving motor is started again. The output shaft of the driving motor rotates to drive the screw rod to rotate, driving the first connecting seat 31 to move. Then, the first tire expanding plate 32 is installed at an appropriate height according to the height of the tire 6 and locked and fixed by the first locking member 33. The first tire expanding plate 32 clamps the front part inside the tire 6. Then, the output shaft of the driving motor drives the first connecting seat 31 to move outwards, and then the tire expanding operation begins, which is convenient for disassembling or installing the tire 6 from the wheel hub. When performing the tire expanding operation, if only the first tire expanding plate 32 and the second tire expanding plate 42 are used to clamp the tire 6, shaking may occur. The rubber pads 74 on the front and rear sides can protect the tire 6. When the tire 6 is undergoing the tire expanding operation, it will contact and squeeze the rubber pads 74. While protecting the tire 6, the rubber pads 74 increase the contact area with the tire 6, making the tire 6 more stable during the tire expanding process.

[0024] Embodiment 2

[0025] On the basis of Embodiment 1, as Figure 1 、 Figure 2 and Figure 4 shown, it further includes a rotating mechanism 8. The rotating mechanism 8 includes an adjusting member 81. The adjusting member 81 is installed on the workbench 1. The adjusting member 81 includes an adjusting screw rod and a knob. The left part of the workbench 1 is rotatably connected with the adjusting screw rod. The adjusting screw rod is equipped with a knob. A second connecting plate 82 is threadedly connected to the adjusting screw rod. A servo motor 83 is installed on the second connecting plate 82. A second roller 84 is connected to the output shaft of the servo motor 83. The second roller 84 is rotatably connected to the second connecting plate 82. Rubber blocks are provided on the second roller 84.

[0026] It should be noted that when expanding the tire, it may be necessary to rotate the tire 6 so as to perform tire expansion treatment on different positions of the tire 6, so as to disassemble or install the tire 6 more quickly. The knob can be rotated to drive the adjustment screw rod to rotate, and then drive the second connecting plate 82 to move to a suitable position. Then, the servo motor 83 is turned on. The output shaft of the servo motor 83 rotates to drive the second roller 84 to rotate. The rubber block on the second roller 84 increases the contact area with the tire 6. At the same time, the conveying rollers on the placing plate 5 make it more convenient for the tire 6 to rotate.

[0027] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form. Any technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
