AI Technical Summary
When grinding and clamping the second-level thin-walled inner ring in wind power gearbox, the radial force can easily cause the parts to deform, resulting in unstable clamping.
A wind power thin-wall internal ring grinding clamping tool is designed, adopting more than 3 sets of clamping structures, each set of structures including contour blocks, sleeves, positioning bolts, pressing plates, clamping screws and nuts, through pressing plates The fit with the clamping screw ensures that the clamping force is applied axially and avoids radial forces.
It effectively avoids the deformation problem of secondary thin-walled internal gear rings when grinding teeth, ensures clamping stability, and because the clamping area is relatively small, it has little impact on the overall metering and can be ignored.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of tooling, in particular to a wind power thin-wall internal gear ring grinding and clamping tooling. Background Art
[0002] Wind power generation has developed rapidly in recent years due to its advantages such as zero pollution and low construction cost.
[0003] In wind turbine gearboxes, the secondary internal gear ring generally has a relatively large diameter and width, and is a thin-walled internal gear ring. When grinding and clamping, the fixture clamps it from the periphery, and the radial force can easily cause deformation of the parts. Utility Model Content
[0004] The utility model provides a wind power thin-walled internal gear ring grinding clamping tool, which aims to solve the shortcomings of the prior art and enable the secondary thin-walled internal gear ring grinding clamping in a wind power gear box to not cause deformation of parts.
[0005] The technical solution adopted by the utility model to solve its technical problems is:
[0006] Wind power thin-walled internal gear ring grinding clamping tooling, characterized by:
[0007] With more than 3 sets of clamping structures;
[0008] Each set of clamping structure includes equal height blocks, sleeves, positioning bolts, pressure plates, clamping screws and nuts;
[0009] The equal-height blocks are placed flat and fixed on the workbench, and the upper end surfaces of the equal-height blocks are located on the same horizontal plane;
[0010] Place the inner gear ring flat on a block of equal height;
[0011] The sleeve is placed on the equal height block, and the positioning bolts are screwed into the vertical screw holes provided in the sleeve;
[0012] The two ends of the pressure plate are pressed on the top of the positioning bolt and the upper end surface of the inner gear ring respectively. The clamping screw passes through the through hole opened in the pressure plate and is screwed into the screw hole opened in the equal height block. The nut is screwed on the upper end of the clamping screw and presses the pressure plate.
[0013] The inner gear ring is pressed against the equal height block by the pressure plate.
[0014] The tooling has a total of 4 sets of clamping structures, and the 4 sets of clamping structures are evenly distributed around the circumference.
[0015] The top of the positioning bolt is flush with the upper end surface of the inner gear ring.
[0016] The utility model is beneficial in that:
[0017] The clamping method of the utility model makes the clamping force press on the ring body of the inner gear ring from top to bottom, which is an axial force, and there is no radial force, which will not cause deformation of the secondary thin-walled inner gear ring. Because the four clamping areas are relatively small, the impact on the overall meter is very small and can be ignored. BRIEF DESCRIPTION OF THE DRAWINGS
[0018] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0019] Figure 1 It is a schematic diagram of the structure of the utility model;
[0020] Figure 2 for Figure 1 Enlarged view of part A. DETAILED DESCRIPTION
[0021] In order to more clearly illustrate the technical solution of the utility model, the following will briefly introduce the drawings required for the description. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other embodiments can be obtained based on these drawings without creative work. In order to facilitate the understanding of the utility model, the following will be combined with the drawings and specific embodiments to explain the utility model in more detail.
[0022] It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element, or one or more centered elements can exist between them. When an element is described as being "connected" to another element, it can be directly connected to the other element, or one or more centered elements can exist between them. The terms "upper", "lower", "inner", "outer", "bottom", etc. used in this specification indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second", "third", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.
[0023] like Figure 1 , Figure 2 As shown:
[0024] The tooling has 4 sets of clamping structures evenly distributed around the circumference.
[0025] Each set of clamping structures comprises equal-height blocks 7 which are placed flat and fixed on a workbench, and the upper end surfaces of the four equal-height blocks 7 are located on the same horizontal plane.
[0026] The inner gear ring 4 is placed flat on four blocks 7 of equal height.
[0027] The sleeve 5 is placed on the equal height block 7 , and the positioning bolt 6 is screwed into the vertical screw hole 51 provided in the sleeve 5 .
[0028] The positioning bolt 6 is rotated to make it rise and fall, and the top of the positioning bolt 6 is adjusted to be substantially flush with the upper end surface of the inner gear ring 4.
[0029] The two ends of the pressure plate 1 are respectively pressed on the top of the positioning bolt 6 and the upper end surface of the inner gear ring 4. The clamping screw 3 passes through the through hole 11 opened in the pressure plate 1 and is screwed into the screw hole 71 opened in the equal height block 7. The nut 2 is screwed on the upper end of the clamping screw 3 and presses the pressure plate 1.
[0030] In this way, the inner gear ring 4 is pressed against the equal height block 7 by the pressing plate 1 .
[0031] The above 4 sets of clamping structures can be used flexibly and meet the load-balancing requirements.
[0032] The outer circumferential stop of the upper end face of the inner gear ring 4 is gauged, and the clamping position is skipped. If the gauge needle is qualified, the gear grinding can be arranged for repair. Because the four clamping areas are relatively small, the impact on the overall gauge is very small and can be ignored.
[0033] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments, and the same and similar parts between the embodiments can be referred to each other. The above description of the disclosed embodiments enables professionals and technicians in this field to implement or use the utility model. Various modifications to these embodiments will be obvious to professionals and technicians in this field, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the utility model. Therefore, the utility model will not be limited to the embodiments shown herein, but will conform to the widest range consistent with the principles and novel features disclosed herein.
