Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tire installation tools, in particular to an auxiliary tool for pressing and installing tires on a matching vertical tire installation machine. Background Art
[0002] At present, in the tractor assembly industry, vertical tire mounting machines are commonly used. During the use of the vertical tire mounting machine, when the tire is pressed, the rim and spoke plate assembly must first be fixed to the clamping claws of the vertical tire mounting machine pressure plate, and then the tire is hoisted onto the rim for pressing.
[0003] Due to the heavy weight of the inner and outer tires of the rim, the tire is suspended on the rim without fixed support and limitation. It is necessary to use a crane hoist for auxiliary lifting. The hoist is always suspended during the tire pressing process, which is inconvenient. In addition, the tire is very easy to fall off during the pressing process, which poses a safety risk. Secondly, after the vertical tire mounting machine has completed the pressing of the inner side of the tire, there is no positioning starting point when pressing the outer side, which can easily cause the edge of the tire to disengage after pressing, which is not conducive to normal pressing. Therefore, the development of new auxiliary tools for pressing tires on vertical tire mounting machines is particularly important. Utility Model Content
[0004] The utility model aims to provide an auxiliary tool for pressing tires on a matching vertical tire mounting machine. The device plays a positioning and limiting role when pressing the outer rim, can be quickly assembled and disassembled, and can improve the production efficiency during the tire pressing process.
[0005] The technical solution adopted by the utility model is: an auxiliary tool for pressing tires on a matching vertical tire mounting machine, comprising a positioning chuck welding part;
[0006] One end of the positioning clamp welded part has a fixed clamp, and the middle part of the positioning clamp welded part is rotatably connected to a movable clamp corresponding to the fixed clamp via a rotating shaft;
[0007] A clamping nut is connected to the positioning chuck weldment, and a clamping screw weldment is threadedly connected to the clamping nut. The clamping screw weldment has an extrusion end facing the movable chuck. The clamping screw weldment moves and squeezes the movable chuck by cooperating with the thread of the clamping nut, so that the movable chuck cooperates with the fixed chuck to clamp the rim of the tire.
[0008] As a preferred solution, an elastic retaining member is connected between the fixed chuck and the movable chuck to enable the two to remain in an open state when not affected by the clamping screw welding member.

[0012] As a preferred solution, the clamping nut is rotatably connected to the positioning clamp weldment.
[0013] As a preferred solution, the clamping screw rod weldment includes a screw rod and a handle fixed at the rear end of the screw rod.
[0014] As a preferred solution, anti-slip grooves are provided on the clamping surfaces of the fixed clamp and the movable clamp that contact the edge of the rim.
[0015] As a preferred solution, the anti-slip grooves of the movable clamp are distributed on both sides of the clamping surface, so that the middle of the clamping surface forms a hollow protection area that does not contact the edge of the rim during clamping.

The words "one", "an" or "the" and the like used in the patent application specification and claims of this utility model do not express quantitative restrictions, but indicate the existence of at least one; the "first", "second" and "third" used in this article should not be regarded as restrictions on the order of components, but are only used to distinguish different components; "include" or "comprise" and other similar words indicate that the elements or objects appearing before "include" or "comprise" include the elements or objects listed after "include" or "comprise" and their equivalents, but do not exclude other elements or objects with the same function.
[0031] In order to more clearly describe the specific structure and use process of the tire pressing auxiliary tool, Figure 1-3 Describe this embodiment:
[0032] like Figure 1 As shown, an auxiliary tool for pressing tires on a supporting vertical tire mounting machine is used. The positioning clamp weldment 1 serves as a support for the overall skeleton of the tooling. A fixed clamp 9 is provided at one end of the positioning clamp weldment 1. A movable clamp 6 corresponding to the fixed clamp 9 is rotatably connected to the middle part of the positioning clamp weldment 1 through a rotating shaft 5. The movable clamp 6 is rotatable and cooperates with the fixed clamp 9 to have a rotating opening and closing function.
[0033] A clamping nut 7 is connected to the positioning chuck weldment 1, and a clamping screw weldment 8 is threadedly connected to the clamping nut 7. The clamping screw weldment 8 has an extrusion end facing the movable chuck 6. The clamping screw weldment 8 moves and squeezes the movable chuck 6 by cooperating with the thread of the clamping nut 7, so that the movable chuck 6 cooperates with the fixed chuck 9 to clamp the rim of the tire.
[0034] The other end of the positioning clamp weldment 1 is bent to form a hanging portion 10 for connecting with an external lifting device.
[0035] An elastic retainer is connected between the fixed chuck 9 and the movable chuck 6 to keep the two in an open state when not affected by the clamping screw weld 8. The clamping screw weld 8 is rotated to move it away from the movable chuck 6, and the movable chuck 6 is opened by the tension of the return spring 3. Then the press-fitting tool is fixed to the rim, and the thread of the clamping screw weld 8 is tightened to squeeze and bring the movable chuck 6 close to the fixed chuck 9. The movable chuck 6 and the fixed chuck 9 are clamped on both sides of the edge of the rim for fixing.
[0036] Specifically, the elastic retaining member can be a return spring 3, and the specific installation method is that a pin 2 is fixed on the positioning clamp weldment 1, a screw 4 is fixed on the movable clamp 6, and the two ends of the return spring 3 are connected to the pin 2 and the screw 4 respectively.
[0037] In order to ensure the stability of the clamping screw weldment 8 and the movable chuck 6 in the extrusion state, a ball groove 11 corresponding to the extrusion end of the clamping screw weldment 8 is provided on the side of the movable chuck 6. When clamping, the extrusion end of the clamping screw weldment 8 is pressed against the ball groove 11, which is more stable.
[0038] The clamping nut 7 is rotatably connected to the positioning clamp weldment 1, and the clamping screw weldment 8 can also rotate with the clamping nut 7, so that under the action of the return spring 3, the extruded end of the clamping screw weldment 8 is always pressed in the ball groove 11.
[0039] The clamping screw weldment 8 includes a screw and a handle fixed at the end of the screw. The clamping nut 7 is cylindrical in shape, with a threaded hole radially extending through the middle thereof. The screw passes through the threaded hole and the screw is driven to rotate by the handle, thereby causing the screw to produce a linear displacement relative to the clamping nut 7.
[0040] In order to improve the stability of the movable clamp 6 and the fixed clamp 9 during clamping, anti-slip grooves are provided on the clamping surfaces where the fixed clamp 9 and the movable clamp 6 contact the rim edge to increase the clamping friction and ensure that the clamping is in place and will not loosen.
[0041] like Figure 2As shown, in order to prevent the clamping grooves of the movable clamp 6 from scratching the painted surface of the rim, the movable clamp is optimized and innovatively designed so that the anti-slip grooves of the movable clamp 6 are distributed on both sides of the clamping surface, so that the middle part of the clamping surface forms a hollow protection area 12 that does not contact the edge of the rim during clamping, and the middle surface is hollowed out to prevent the painted surface of the edge of the rim from being scratched after clamping.
[0042] The following is a complete overview of the use of auxiliary tools for vertical tire mounting machines:
[0043] When releasing: the clamping screw welded part 8 is rotated to reduce the pressure on the movable clamp 6, and under the pulling action of the return spring 3, the movable clamp 6 and the fixed clamp 9 are separated;
[0044] During installation: rotate the clamping screw weldment 8 so that its extrusion end applies pressure to the movable chuck 6 to overcome the pulling force of the return spring 3. The movable chuck 6 and the fixed chuck 9 approach and clamp on both sides of the rim edge. The extrusion end of the rotating clamping screw weldment 8 presses against the ball groove 11 of the movable chuck 6 to remain stable.
[0045] The parts not described in detail in this embodiment are prior art.
[0046] It should be noted that although the utility model is described through the above embodiments, the utility model can also have other multiple embodiments. Without departing from the spirit and scope of the utility model, it is obvious that those skilled in the art can make various corresponding changes and deformations to the utility model, but these changes and deformations should all fall within the scope of protection of the attached claims of the utility model and their equivalents.
