Technical Field
[0001] The utility model relates to the technical field of thrust head clamp ring disassembly, in particular to a thrust head clamp ring disassembly structure. Background Art
[0002] As a rotating part, the thrust head needs to be connected to the main shaft. The thrust head and the main shaft are usually full-circle structures. In order to tighten the thrust head and the main shaft, a snap ring needs to be inserted into the gap between them when they are assembled. Due to the large tightening force, it is difficult to remove the snap ring. One method is to set a hook on the side of the snap ring and pull it out from the side with an electric hoist. However, due to the limited thickness of the snap ring, this method can easily cause the snap ring to deform and cannot be used again. Utility Model Content
[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a thrust head clamping ring disassembly structure, which can solve the problem that the measuring thrust head clamping ring is easily deformed when being disassembled using an electric hoist.
[0004] To this end, the utility model adopts the following technical solutions:
[0005] A thrust head clamping ring disassembly structure, a clamping ring is arranged between the thrust head and the main shaft, the clamping ring is composed of a first clamping ring semicircle and a second clamping ring semicircle, a fixing key is fixed on the top of the thrust head, the fixing key is tightly attached to the outer edge of the second clamping ring semicircle, a detachable inclined block is respectively arranged at the connection between the two ends of the first clamping ring semicircle and the second clamping ring semicircle, and a detachable angle block is inserted between the inclined block and the first clamping ring semicircle.
[0006] On the basis of adopting the above technical solutions, the present invention can also adopt the following further technical solutions, or use these further technical solutions in combination:
[0007] A side surface of the inclined block away from the fixed key is an inclined surface.
[0008] The side surface of the angle block that fits the inclined block is an inclined surface, and the end of the angle block inserted between the inclined block and the first clamping ring semicircle is a wedge-shaped tip.
[0009] The length of the inclined block inserted into the clamping ring does not exceed half of the ring width.
[0010] The materials of the inclined block and the angle block are both iron.
[0011] Compared with the prior art, the utility model has the following advantages and beneficial effects: the snap ring is divided into a first snap ring semicircle and a second snap ring semicircle, and a fixing key is arranged on one side of the second snap ring semicircle, and an inclined block and an angle block are arranged between the first snap ring semicircle and the second snap ring semicircle, so that the first snap ring semicircle can be disassembled conveniently, and then the second snap ring semicircle can be disassembled, with little damage and can be repeated many times. The operation process is simple and labor-saving, and there is no need to use a starting machine. The structure is simple, reliable and the cost is low. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.
[0016] The utility model provides a thrust head clamping ring disassembly structure, wherein a clamping ring 3 is arranged between a thrust head 2 and a main shaft 1, the clamping ring 3 is composed of a first clamping ring semicircle 31 and a second clamping ring semicircle 32, a fixing key 6 is fixed on the upper surface of the thrust head 2, the fixing key 6 is tightly attached to the outer edge of the second clamping ring semicircle 32, a detachable inclined block 4 is respectively arranged at the connection between the two ends of the first clamping ring semicircle 31 and the second clamping ring semicircle 32, and a detachable angle block 5 is inserted between the inclined block 4 and the first clamping ring semicircle 31.
[0017] A side surface of the inclined block 4 away from the fixed key 6 is an inclined surface.
[0018] The side surface of the angle block 5 that is in contact with the inclined block 4 is an inclined surface, and the end of the angle block 5 inserted between the inclined block 4 and the first clamping ring semicircle 31 is a wedge-shaped tip.
[0019] like Figure 2 As shown, the plane of the inclined block 4 is a right-angled trapezoid, and the plane of the angled block 5 is a triangle.
