A tire changing machine working plate

Abstract

The present invention discloses a working disc of a tire removal machine, comprising a disc body, a mounting sleeve being provided on the disc body, the disc body and the mounting sleeve being integrally cast, and the disc body and the mounting sleeve being made of aluminum alloy. The present invention adopts aluminum alloy material for die-casting, which reduces the manufacturing process and reduces the labor cost. The aluminum alloy material does not need chrome plating, which reduces the environmental pollution during the chrome plating process. The disc body and the mounting sleeve are integrally formed, which avoids welding and welding defects that may occur during the welding process, and at the same time avoids smoke and dust during the welding process, thereby reducing air pollution. The disc body is provided with a reinforcement structure, which can increase the strength of the disc body on the one hand, and on the other hand, can restore the deformation of the disc body during operation, so that the disc body can continue to be used normally.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figure 1-4 As shown, a working disc of a tire changing machine comprises a disc body 1, on which a mounting sleeve 2 is arranged, the disc body 1 and the mounting sleeve 2 are integrally cast, and the disc body 1 and the mounting sleeve 2 are made of aluminum alloy.

[0027] Existing working disks are all made of steel, and the processing procedures are: cutting steel plates; grinding edges; turning edges; welding navels; surface flattening; turning surfaces and inner holes; milling grooves in machining centers; keyway processing on broaching machines; chrome plating on the outside; marking scales. The procedures are complicated, the processing cost is high, and the production efficiency is low. The working disk in the present invention is made of aluminum alloy, and the procedures are as follows: melting aluminum ingots and die-casting them in a die-casting machine; turning the surface and inner holes of the formed workpiece; milling grooves in machining centers; keyway processing on broaching machines; marking scales. Die-casting aluminum materials and processing them into working disks greatly reduces the processing procedures, reduces costs, and improves production efficiency.

[0028] The disk body 1 includes a working surface 11 and a reinforcement surface 12. The reinforcement surface 12 is provided with a reinforcement structure, which is used to improve the strength of the disk body 1. The reinforcement structure includes a first reinforcement rib 101, a second reinforcement rib 102 and a third reinforcement rib 103. The disk body 1 is provided with a slide groove 13. The first reinforcement rib 101 extends from the mounting sleeve 2 along the slide groove 13 and extends to the outer periphery of the reinforcement surface 12 on both sides of the slide groove 13. The second reinforcement rib 102 is circumferentially arranged at the outer edge of the reinforcement surface 12. The third reinforcement rib 103 extends outward from the mounting sleeve 2, and the height of the third reinforcement rib 103 gradually decreases from the mounting sleeve 2 to the outside.

[0029] There are four groups of third reinforcing ribs 103 , each group includes two parallel third reinforcing ribs 103 , and the angles between each third reinforcing rib 103 and its adjacent slide groove 13 are equal.

[0030] In this embodiment, there are 4 first reinforcing ribs 101, which extend outward from the mounting sleeve 2 to the slide groove 13. The width of the first reinforcing rib 101 is greater than the width of the slide groove 13, and the first reinforcing rib 101 continues to extend in the direction of the slide groove 13. The first reinforcing rib 101 increases the strength of the working disk near the slide groove 13. The second reinforcing rib 102 is arranged along the outer edge of the reinforcing surface 12, and is arranged along the shape of the disk body to strengthen the overall strength of the working disk. There are 8 third reinforcing ribs 103, each in a group of 2, for a total of 4 groups. Each group of third reinforcing ribs 103 is arranged at intervals from the first reinforcing rib 101, and the first reinforcing rib 101 and the third reinforcing rib 103 are arranged in a similar cross shape. The first reinforcing rib 101, the second reinforcing rib 102 and the third reinforcing rib 103 cooperate to greatly improve the overall strength of the working disk, and enable the working disk to have the ability to recover deformation after work.

[0031] A reinforcement portion 104 is provided between each group of third reinforcement ribs 103. The reinforcement portion 104 is stepped, and the connecting surface 105 between the top surface and the reinforcement surface 12 is a conical surface. The reinforcement portion 104 is a part of a frustum. The reinforcement portion 104 improves the strength of the working disk and can also avoid stress concentration between the mounting sleeve 2 and the disk body 1, thereby increasing the service life of the working disk.

[0032] This embodiment further includes a fourth reinforcing rib 106, which starts from the connection between the first reinforcing rib 101 and the third reinforcing rib 103, extends to the second reinforcing rib 102 and is connected to the second reinforcing rib 102. The fourth reinforcing rib 106 further improves the strength of the working disc.

[0033] The first reinforcing rib 101 is provided with a square slot 107 disposed between the slide slot 13 and the mounting sleeve 2. The slot 107 can reduce the overall mass of the working disc and improve the anti-deformation capability of the working disc 1 near the mounting sleeve 2.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
