Embodiment 1

[0034] Such as figure 1 with figure 2 As shown, the positioning tool for fan gear drilling includes a rectangular base 10, on which a turntable 9 is installed for rotation, and a thimble sleeve 13 is connected with a vertical bolt in the center of the base 10. Both ends of the thimble sleeve 13 are open, and the top of the thimble sleeve 13 runs through Turntable 9 tops. A thimble 11 is vertically slidably connected in the thimble sleeve 13 , the top of the thimble 11 is conical with a taper of 60°, and a compensating spring 12 is connected between the bottom of the thimble 11 and the base 10 . The thimble 11 is used to insert in the center hole of the bottom of the workpiece to center the workpiece.

[0035] There are three support discs 7 ( figure 2 Only two are shown in the figure), and three support discs 7 are arranged on the turntable 9 in a circular array with the center of the turntable 9 as the array center. All the three turntables 9 are rotatably connected wit...

Abstract

The invention relates to the technical field of fan gear machining, in particular to a positioning tool for fan gear drilling. The positioning tool comprises a base and an indexing mechanism for indexing workpieces, wherein a rotating disc is rotationally arranged on the base, a positioning mechanism for positioning the workpieces is arranged on the rotating disc, and a fixing mechanism for fixing the rotating disc is further arranged on the base; the positioning mechanism comprises a plurality of supporting discs fixed to the top of the rotating disc, and the supporting discs are annularly arrayed on the rotating disc with the circle center of the rotating disc as the array center; and adjusting discs are rotationally connected to the supporting discs, the rotating centers of the adjusting discs deviate from the circle center of the adjusting discs, and the area defined by the adjusting discs is a placement area for allowing the workpieces to be placed. The positioning tool for fan gear drilling can solve the problem that an existing tool can only position gears with one type.

Description

technical field [0001] The invention relates to the technical field of fan gear processing, in particular to a positioning tool for drilling fan gears. Background technique [0002] During the production and processing of fan gears, operations such as drilling, turning, and grinding are required. Among them, when it is necessary to drill a circle of holes on the end face of the gear, at present, the gear is generally hoisted to the positioning tool for positioning, and a circle of holes is drilled on the end face of the gear by driving the tool to rotate. When drilling, it is necessary to ensure the angle of each rotation of the tool The same, so as to ensure that the spacing of each hole on the gear is the same. [0003] The existing positioning tool can only locate one type of gear, and another set of positioning tool needs to be set up when other types of gears need to be processed, and the equipment cost is high. Contents of the invention [0004] The present inventi...
