Abstract
Description
Technical Field
[0001] The utility model relates to the field of tooling, in particular to a tooling for clamping a large-thickness internal gear ring gear grinding. 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 the wind power gearbox, the thick inner gear ring is heavy in quality and rigid. When grinding the gear, the lower end of the inner gear ring must be clamped with a tool first, and then the upper end of the outer circle stop is aligned with the tapping table. The current clamping tools have low operating efficiency when aligning the tapping table. Utility Model Content
[0004] The utility model provides a large-thickness internal gear ring grinding clamping tooling, which aims to solve the shortcomings of the prior art. After the large-thickness internal gear ring is clamped, the entire circle of the thread surface can be aligned smoothly and efficiently during the gear grinding process.
[0005] The technical solution adopted by the utility model to solve its technical problems is:
[0006] The clamping tool for grinding gear of large thickness internal gear ring is characterized by:
[0007] More than three equal-height blocks are fixedly connected to the workbench, and the inner gear ring is horizontally placed on the equal-height blocks;
[0008] Each height-equalizing block is equipped with a positioning sleeve, and the screw section of the positioning sleeve extending downward is screwed into the screw hole on the upper surface of the height-equalizing block, thereby fixing the positioning sleeve to the height-equalizing block;
[0009] The positioning sleeve has a transverse screw hole, and the clamping screw is screwed into the transverse screw hole and passes through the positioning sleeve, and the end of the clamping screw bears against the outer circle of the inner gear ring 1.
[0010] Further:
[0011] It has 4 equal-height blocks evenly distributed around the circumference.
[0012] Further:
[0013] The fixing screws pass through the through holes on the equal height block and are screwed into the screw holes on the workbench to fix the equal height block to the workbench.
[0014] Further:
[0015] Each equal height block is equipped with 2 fixing screws.
[0016] Further:
[0017] The end of the clamping screw presses against the copper plate, and the copper plate presses against the outer circle of the inner gear ring.
[0018] The utility model is beneficial in that:
[0019] The utility model uses equal height blocks and clamping screws to conveniently adjust the position of a thick inner gear ring workpiece with the clamping screws, so that the center of the part can be quickly aligned, so that the calibration of the gear ring stop is smooth and efficient, thereby improving the gear ring grinding clamping efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0021] Figure 1 It is a schematic diagram of the structure of the utility model. DETAILED DESCRIPTION
[0022] 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.
[0023] 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.
[0024] like Figure 1 As shown:
[0025] There are 4 equal height blocks 5, which are evenly distributed around the circumference. The equal height blocks 5 are placed according to the size of the outer circle of the thick inner gear ring 1 to be processed. Each equal height block 5 is equipped with 2 fixing screws 6. The fixing screws 6 pass through the through holes 51 on the equal height blocks 5 and are screwed into the screw holes 71 on the workbench 7 to fix the equal height blocks 5 to the workbench 7.
[0026] Each height-equalizing block 5 is provided with a positioning sleeve 4, and a screw section 42 extending downward from the positioning sleeve 4 is screwed into a screw hole 52 on the upper surface of the height-equalizing block 5, thereby fixing the positioning sleeve 4 to the height-equalizing block 5;
[0027] The inner gear ring 1 is placed horizontally on four blocks 5 of equal height.
[0028] The positioning sleeve 4 has a transverse screw hole 41, the clamping screw 3 is screwed into the transverse screw hole 41 and passes through the positioning sleeve 4, the end of the clamping screw 3 presses against the copper plate 2, the copper plate 2 presses against the outer circle of the inner gear ring 1, and the copper plate 2 can protect the outer circle of the inner gear ring 1.
[0029] In this way, the four clamping screws 3 clamp the outer circle of the inner gear ring 1, and start to gauge the outer circle stop 11 of the upper end face of the inner gear ring 1. Adjust and move the inner gear ring 1 according to the gauge runout. If the runout is qualified, finally clamp the inner gear ring 1 with the clamping screws 3 and arrange for gear grinding and repair.
