Abstract
Description
Technical Field
[0001] The utility model relates to the field of tooling, in particular to an internal spline shaft gear-inserting 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 internal spline shaft is usually processed together with the gear assembly. As the reliability requirements of wind turbine gearboxes continue to increase, the spline shaft needs to be nitrided to enhance performance and wear resistance. In this case, the spline shaft needs to be processed separately.
[0004] Since a large offset force is generated during processing, a more stable tooling is required to clamp the internal spline shaft to ensure processing accuracy. Utility Model Content
[0005] The utility model provides an internal spline shaft gear shaping clamping tool, which aims to solve the shortcomings of the prior art, firmly clamp the internal spline shaft, and ensure the precision of the internal spline shaft gear shaping processing.
[0006] The technical solution adopted by the utility model to solve its technical problems is:
[0007] Internal spline shaft gear clamping fixture, characterized by:
[0008] The tooling bracket is fixed on the workbench by screw connection;
[0009] The lower end surface of the internal spline shaft is placed horizontally on the upper end surface of the tooling bracket;
[0010] Three or more equal-height blocks are placed on the upper end surface of the tooling corbel;
[0011] The lower pressing plate is pressed on the lower step end face of the internal spline shaft, and the stud bolt passes through the through hole of the lower pressing plate and the through hole of the equal height block, and is screwed into the screw hole of the tooling bracket, and the nut is screwed on the stud bolt and presses the lower pressing plate;
[0012] A sleeve is placed on the upper surface of the lower pressing plate, and bolts are screwed into screw holes opened on the upper surface of the sleeve;
[0013] The two ends of the long pressure plate are pressed on the upper end surface of the bolt and the upper step end surface of the internal spline shaft respectively;
[0014] After passing through the through hole of the long pressing plate, the stud is screwed into the screw hole of the lower pressing plate, and the nut is screwed on the stud and presses the long pressing plate.
[0015] The equal height blocks are evenly distributed around the circumference on the upper end surface of the tooling corbel.
[0016] The lower pressing plate pressed on the lower step end surface of the inner spline shaft is an annular pressing plate, and the shaft hole of the annular pressing plate is sleeved outside the inner spline shaft.
[0017] The sleeves are evenly distributed around the circumference of the annular pressure plate.
[0018] The lower end surface of the long pressure plate is flush with the upper step end surface of the internal spline shaft.
[0019] The utility model is beneficial in that:
[0020] The utility model presses the upper and lower step end faces of the internal spline shaft by tightening two pressing plates in cooperation with the double-headed screw rod, thereby providing a more stable double support for the vertical internal spline shaft, clamping the internal spline shaft on the workbench, overcoming the large offset force generated during processing, and clamping the internal spline shaft to ensure processing accuracy. BRIEF DESCRIPTION OF THE DRAWINGS
[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0022] Figure 1 It is a schematic diagram of the structure of the utility model. DETAILED DESCRIPTION
[0023] 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.
[0024] The use process of the utility model tooling is as follows: Figure 1 As shown:
[0025] 1. The tooling bracket 6 is connected and fixed to the workbench 13 by screws 12;
[0026] 2. The lower end surface of the internal spline shaft 1 is placed horizontally on the upper end surface of the tooling bracket 6;
[0027] 3. Four equal-height blocks 5 are evenly distributed around the circumference on the upper end surface of the tooling corbel 6, and the vertical through holes 51 formed in the equal-height blocks 5 are aligned with the screw holes 61 formed in the upper end surface of the tooling corbel 6;
[0028] 4. The shaft hole 40 of the annular pressure plate 4 is sleeved on the outer side of the internal spline shaft 1, and the annular pressure plate 4 is pressed on the lower step end face 14 of the internal spline shaft 1. The stud 2 passes through the through hole 41 of the annular pressure plate 4 and the through hole 51 of the equal height block 5, and is screwed into the screw hole 61 of the tooling bracket 6. The nut 11 is screwed on the stud 2 and presses the annular pressure plate 4. In this way, the annular pressure plate 4 presses the lower step end face 14 of the internal spline shaft 1, thereby pressing the internal spline shaft 1 on the tooling bracket 6;
[0029] 5. Four sleeves 3 are evenly distributed on the circumference of the upper surface of the annular pressure plate 4. The upper surface of the sleeve 3 is provided with screw holes 31, and the bolts 9 are screwed into the screw holes 31;
[0030] 6. The two ends of the long pressure plate 2 are respectively pressed on the upper end surface of the bolt 9 and the upper step end surface 15 of the internal spline shaft 1 (there are a total of 4 long pressure plates 2 corresponding to 4 bolts 9). The height of the bolt 9 is adjusted by screwing in or out the bolt 9 to ensure that the lower end surface of the long pressure plate 2 is flush with the upper step end surface 15 of the internal spline shaft 1;
[0031] 7. The stud 7 passes through the through hole 21 of the long pressing plate 2 and is screwed into the screw hole 42 of the annular pressing plate 4. The nut 8 is screwed on the stud 7 and presses the long pressing plate 2. In this way, the long pressing plate 2 presses the upper step end face 15 of the internal spline shaft 1, thereby further pressing the internal spline shaft 1 onto the tooling bracket 6. This structure is clamped.
