[0006] A wind power high-speed shaft gear grinding clamping tool, characterized by:
[0007] The plate is fixed on the workbench, the positioning sleeve is fixed on the plate, the lower end of the high-speed shaft is vertically inserted into the positioning sleeve, and the step surface of the high-speed shaft is mounted on the upper end surface of the positioning sleeve; the screw passes through the middle hole of the plate from bottom to top and then screws into the central screw hole of the bottom end surface of the high-speed shaft, and the screw head is tightly against the lower end surface of the plate.
[0008] A rib plate is welded to the lower surface of the flat plate, the rib plate is welded to the upper surface of the bottom plate, and the bottom plate is fixed on the workbench.
[0009] A rib plate having four circumferentially evenly distributed ribs is welded to the lower surface of the flat plate.
[0010] The utility model has four bolts evenly distributed on the circumference, and the bolts respectively pass through four waist-shaped grooves opened on the bottom plate and are screwed into four screw holes of the workbench, so as to fix the bottom plate to the workbench.
[0011] The utility model is beneficial in that:
[0012] The clamping method of the utility model tightens the high-speed shaft by tightening bolts on the welding assembly, can efficiently clamp the high-speed shaft for gear grinding, and will not damage the surface of the completed shaft diameter of the high-speed shaft. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0014] Figure 1 It is a schematic diagram of the structure of the utility model. DETAILED DESCRIPTION
[0015] 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.
[0016] 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.
[0017] like Figure 1 As shown:
[0018] The use process of this utility model tooling:
[0019] 1. The positioning sleeve 2, the flat plate 4, the rib plate 5 (4 in number), and the bottom plate 6 are connected by welding to form an integral component of a combined body. The positioning sleeve 2 is welded to the flat plate 4. Four rib plates 5 evenly distributed around the circumference are welded to the lower surface of the flat plate 4. The rib plate 5 is welded to the upper surface of the bottom plate 6. The bottom plate 6 is horizontally placed on the equipment workbench 7 and has four circumferentially evenly distributed bolts 8. The bolts 8 pass through four waist-shaped grooves 61 provided on the bottom plate 6 and are screwed into four screw holes 71 of the workbench 7, thereby fixing the positioning sleeve 2, the flat plate 4, the rib plate 5, and the bottom plate 6 to the workbench 7;

[0021] 3. The screw 3 passes through the middle hole 40 of the plate 4 from bottom to top, and is screwed into the central screw hole 10 of the bottom end face of the high-speed shaft 1. It is tightened so that the screw head 31 is tightly against the lower end face of the plate 4. In this way, the high-speed shaft 1 is clamped. 4. After the clamping and tightening are completed, if the reference journal of the high-speed shaft 1 is qualified, the gear grinding process can be arranged.
[0022] In this way, the high-speed shaft 1 is vertically clamped and ground by the connection structure of the end face, and the surface of the completed shaft diameter of the high-speed shaft 1 is not touched by the clamp and will not be damaged.
[0023] 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.
