Abstract
The utility model relates to a positioning fixture for a fan box body and an inner ring gear with positioning pin holes, which is composed of a circular base, a positioning block, a horizontal adjusting screw rod and a high precision rotary device, the positioning block is evenly distributed and fixed on the edge of the upper surface of the base, the horizontal adjusting screw rod is in screwed connection with the positioning block with the axis in parallel with the base; the high precision rotary device is composed of a mounting sleeve, a rotary shaft, a bearing, a suspension arm and a fixed ring, and is fixed on the base through the mounting sleeve, the rotary shaft is vertical to the base, and the axis of the rotary shaft pass through the center of the base. The positioning fixture has simple structure, the fan box body and the inner ring gear can be aligned and fixed conveniently on the positioning fixture so that the inner hole axis of the fan box body after fixing is in the same line with the axis of the inner ring gear and the operation is not performed on a vertical lathe, the energy consumption and labor intensity of operators are reduced and the work efficiency is improved.
Description
Technical field
The utility model relates to the positioning fixture of workpiece in the field of machining, particularly fan box and the positioning fixture of ring gear when joining the brill dowel hole.
Background technology
The driving cog casing of wind-driven generator and ring gear are by alignment pin and bolting assembling all-in-one-piece, after fan box and ring gear fixedly combine as a whole, must guarantee that the interior axially bored line of fan box and ring gear axis are located along the same line (as shown in Figure 3).
Dowel hole on fan box and the ring gear is to join to bore to form, and is about to fan box and ring gear overlaps and with after the bolting, bore dowel hole on lathe.After fan box and ring gear overlap, the interior axially bored line of fan box and internal tooth figure axis are located along the same line.Existing method is ring gear and fan box to be positioned over beat the table centering on the vertical lathe, so that the interior axially bored line of fan box and ring gear axis are located along the same line.Because this centering process bothers very much, need to consume the long period, thus not only taken vertical lathe equipment, and workbench is rotated owing to need start vertical lathe, so also expended the energy.
The utility model content
The purpose of this utility model provides a kind of fan box and ring gear is joined the draw-bore positioning fixture, fan box and ring gear can be finished on this positioning fixture make table centering and clamping, the interior axially bored line of clamping rear fan casing and ring gear axis are located along the same line.
Fan box described in the utility model and ring gear are joined the draw-bore positioning fixture, form by garden shape base, locating piece, horizontal adjusting screw(rod) and high accuracy whirligig, locating piece is L-shaped, it evenly arranges and is fixed on the top surface edge of base, horizontal adjusting screw(rod) is screwed on the locating piece, and its axis is parallel with base; The high accuracy whirligig is by installing sleeve, rotating shaft, bearing, cantilever and retainer ring are formed, the rotating shaft lower end is installed on the installing sleeve by bearing, can be with respect to installing sleeve axis rotation around the shaft, cantilever is fixed on the rotating shaft upper end by retainer ring, the high accuracy whirligig is fixed on the base by installing sleeve, and its rotating shaft is vertical with described base, and shaft axis is through the center of base.
Vertically be connected with the vertical adjusting screw rod on base, it is evenly distributed on the base center is on the same circumference in the center of circle.
Its dozen table centering and clamping process are as follows:
Earlier ring gear (also undressed internal tooth) is placed on the locating piece of this positioning fixture, and the horizontal adjusting screw(rod) of rotation is conflicted on the ring gear external cylindrical surface it. on the cantilever of high accuracy whirligig, install the meter tool, the ring gear upper surface is detected, and ring gear is moved in vertical direction by regulating the vertical adjusting screw rod, to guarantee that the ring gear upper end surface is in level. with the meter tool ring gear inner cylinder face is detected again afterwards, and ring gear is moved in the horizontal direction by regulating horizontal adjusting screw(rod), be located along the same line with the axis of assurance ring gear and the shaft axis of high accuracy whirligig. fan box is positioned on the ring gear upper surface again, and the fan box endoporus face of cylinder is detected with the meter tool, and the position of adjusting fan box on the ring gear upper surface, the shaft axis of interior axially bored line of fan box and high accuracy whirligig is located along the same line, so far, just finished fan box and the ring gear centering on positioning fixture, at this moment, the interior axially bored line and the ring gear axis of fan box just are located along the same line. afterwards, with bolt fan box and ring gear are linked into an integrated entity, can lift to carry out on the lathe boring joining of dowel hole and process.
Positioning fixture described in the utility model is simple in structure, fan box and ring gear are made table centering and clamping on this positioning fixture easy to operate, and need not take vertical lathe and operate, to a certain degree reduce energy resource consumption and operator's labour intensity, improve operating efficiency.
