Description

Technical Field

[0001] This utility model belongs to the field of gear processing technology, specifically relating to a clamping mechanism for processing an external gear ring. Background Technology

[0002] An external gear ring is a ring gear with teeth machined on its outer side.

[0003] When machining an external gear ring, gears need to be machined on its outer surface. Since it is inconvenient to use the outer side for fixing, it is necessary to fix it on the inner side.

[0004] Technical problem: Because the external gear rings have different specifications, multiple sets of fixtures are required, which is not conducive to processing. Utility Model Content

[0005] The technical problem to be solved by this utility model is: how to design an external gear ring processing clamping mechanism that can be applied to external gear rings of multiple specifications.

[0006] The specific technical solution of this utility model is as follows: A clamping mechanism for machining external gear rings includes a support frame and multiple clamping rings of various sizes. A supporting cone, smaller at the top and larger at the bottom, is fixed on the support frame. Both the support frame and the supporting cone have through holes at their centers, through which a tie rod passes. A clamping ring is positioned above the support frame, comprising spaced-apart clamping ring hardware units and clamping ring elastic units. Each clamping ring hardware unit extends outwards with a protruding plate, forming a right angle with the protruding plate. A pressure plate is positioned above the supporting cone, fixed to the tie rod. The edge of the pressure plate is connected to an expansion cone via an elastic body. The expansion cone comprises spaced-apart cone hardware units and cone-shaped elastic units. When the expansion cone is not in contact with the clamping rings, all clamping rings have the same inner diameter.

[0007] The clamping ring elastic unit, the elastomer, and the cone hard elastic unit are all made of rubber.

[0008] Compared with the prior art, the technical advantage of this utility model is that it is equipped with an adjustment component, which can clamp even when facing external gear rings of multiple specifications, thus meeting the needs of processing and production. Attached Figure Description

[0010] Figure 2 This is a top-down view of the upward trend.

[0011] Figure 3 This is a top view of the support frame. Detailed Implementation

[0012] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0013] like Figure 1-3 A clamping mechanism for machining an external gear ring includes a support frame 10 and multiple clamping rings 30 of various sizes. A support cone 11 with a smaller upper part and a larger lower part is fixed on the support frame 10. Both the support frame 10 and the support cone 11 have through holes 12 at their centers, and a pull rod 20 passes through the through holes 12.

[0014] A clamping ring 30 is provided above the support frame 10. The clamping ring 30 includes clamping ring hardware units 33 and clamping ring elastic units 32 arranged at intervals. The clamping ring hardware units 33 extend outward to form a protruding plate 31, and the clamping ring hardware units 33 and the protruding plate 31 form a right angle 35.

[0015] A pressure plate 21 is provided above the supporting cone 11. The pressure plate 21 is fixed on the tie rod 20. The edge of the pressure plate 21 is connected to the expansion cone 23 through the elastic body 22. The expansion cone 23 includes cone hardware units 231 and cone hard elastic units 232 arranged at intervals.

[0016] When the expansion cone 23 is not in contact with the clamping ring 30, all the clamping rings 30 have the same inner diameter.

[0017] For ease of processing, the clamping ring elastic unit 32, the elastomer 22, and the cone hard elastic unit 232 are all made of rubber.

[0018] Its working principle is as follows: S1. Installation: Install the tie rod 20 onto the hydraulic cylinder.

[0019] S2. Selection: Select a suitable clamping ring 30 and place it on the support frame 10 according to the inner diameter of the workpiece (external gear ring) 90.

[0020] S3. Placement: Place the workpiece 90 on the protruding plate 31, such as... Figure 1 As shown.

[0021] S4. Clamp: The hydraulic cylinder drives the pull rod 20 to move downwards, which in turn pulls the pressure plate 21, the elastic body 22, and the expansion cone 23 to move downwards simultaneously. At this time, the expansion cone 23 is subjected to the lateral support force of the lower outer contour of the supporting cone 11 and is forced to expand laterally; At this time, the clamping ring 30 is subjected to the lateral support force of the cone hardware unit 231 and is forced to expand laterally; The hydraulic cylinder stops and remains in this state until the inner contour of the lower surface of the workpiece is at a right angle of 35 degrees.

[0022] During the lateral expansion process, the clamping ring elastic unit 32, the elastic body 22, and the cone hard elastic unit 232 all undergo adaptive elastic deformation to meet the requirements of lateral expansion.

[0023] In this way, the workpiece 90 is fixed at a right angle of 35 degrees, and gear teeth can be machined.

[0024] The external gear ring machining clamping mechanism provided by this utility model has the following significant advantages: This utility model has multiple models of clamping rings 30. When facing external gear rings with different inner diameter specifications, the clamping ring 30 of different models can be selected for clamping, thus meeting the needs of processing and production.

[0025] For other details, please refer to the existing technology.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
