The lower part of the positioning boss is connected to the rectangular base plate, and the positioning boss has an inner hole of the positioning boss; the positioning mechanism of the above-mentioned prior art patent is complex and the mechanical cost is high. Summary of the invention

[0003] In view of the problems existing in the prior art, the purpose of the utility model is to provide a quick clamping tool for processing disc brake discs. After the brake disc is sleeved on the surface of the trapezoidal positioning block, the conical column is driven to rise by the cylinder, which can drive the trapezoidal positioning block to expand and fix the brake disc.

[0004] To solve the above problems, the utility model adopts the following technical solutions.

[0005] A quick clamping tool for processing disc brake discs includes a support table, a support ring is fixed on the surface of the support table, a positioning rod is inserted into the inner side of the support ring, a trapezoidal positioning block is fixed to the inner end of the positioning rod, a cylinder is fixed to the bottom of the support table, a conical column is fixed to the end of the cylinder propel rod, a brake disc is tightly fixed on the outer surface of the trapezoidal positioning block, and after the brake disc is sleeved on the surface of the trapezoidal positioning block, the conical column is driven to rise by the cylinder, which can drive the trapezoidal positioning block to expand and fix the brake disc.

[0006] Furthermore, the outer surface of the trapezoidal positioning block is covered with a rubber layer.

[0007] Furthermore, the conical column is fitted onto the inner surface of the trapezoidal positioning block.

[0008] Furthermore, the trapezoidal positioning blocks are evenly distributed on the inner surface of the support ring.

[0009] Furthermore, a spring is sleeved on the outer surface of the positioning rod.

[0010] Furthermore, an insertion hole is provided on the inner surface of the support ring, and the positioning rod is inserted into the insertion hole.

[0011] Furthermore, the outer surface of the conical column is smooth and polished.

[0012] Compared with the prior art, the advantages of the present invention are:

[0013] (1) After the brake disc is put on the surface of the trapezoidal positioning block, the cylinder drives the conical column to rise, which can drive the trapezoidal positioning block to expand and fix the brake disc. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Description of the numbers in the figure:

[0017] 1 support platform, 2 support ring, 3 positioning rod, 4 trapezoidal positioning block, 5 cylinder, 6 conical column, 100 brake disc, 7 spring. DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example 1: Please refer to Figure 1-2 , a quick clamping tool for processing a disc brake disc, comprising a support platform 1, a support ring 2 is fixed on the surface of the support platform 1, a positioning rod 3 is inserted inside the support ring 2, a trapezoidal positioning block 4 is fixed at the inner end of the positioning rod 3, a cylinder 5 is fixed at the bottom of the support platform 1, a conical column 6 is fixed at the end of the cylinder 5 pushing rod, and a brake disc 100 is tightly fixed on the outer surface of the trapezoidal positioning block 4;

[0020] The outer surface of the trapezoidal positioning block 4 is covered with a rubber layer, and when the brake disc 100 is pressed tightly, the rubber layer increases the friction force;

[0021] The conical column 6 is fitted on the inner surface of the trapezoidal positioning block 4, and the trapezoidal positioning block 4 is evenly distributed on the inner surface of the support ring 2. When in use, the brake disc 100 is sleeved on the outer surface of the trapezoidal positioning block 4, and the conical column 6 is lifted by the cylinder 5, which can squeeze the conical positioning block 4 outward to expand, and can drive the trapezoidal positioning block 4 to squeeze and tighten the brake disc 100, which is convenient to fix and the clamping tooling is simple and convenient;

[0022] The outer surface of the positioning rod 3 is sleeved with a spring 7. When the cylinder 5 is reset, the spring 7 drives the trapezoidal positioning block 4 to shrink, and the brake disc 100 can be removed, which is convenient to use.

[0023] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
