Abstract
The invention relates to a positioning device for hole milling of a rocker arm. The positioning device comprises a left positioning seat and a right positioning seat, wherein the left positioning seat is L-shaped; a semi-circular groove is formed in the side edge of the upper platform surface of the left positioning seat; left round holes are formed in the side wall and symmetrical about the semi-circular groove; an adjusting device is arranged on the lower platform surface; a square notch is formed on the edge of the top surface of the right positioning seat; right round holes and a square groove are formed in the front wall and the side wall of the right positioning seat respectively; the right round holes are symmetrical about the square notch; and two bolts respectively penetrate through the left round holes and the right round holes to connect the left positioning seat with the right positioning seat into a whole. The positioning device is simple in structure, simple and convenient to operate and high in processing precision.
Description
Technical field
The present invention relates to technical field of tooling clamps, relate in particular to a kind of positioner to rocking arm cylindrical end end face hole milling.
Background technology
Rocking arm has a square end and cylindrical end, needs processing to portal at the end face of its cylindrical end, is used for being connected with other part, processes this hole and uses lathe, inefficiency, cost height; Now use milling machine that it is milled processing, but the location of rocking arm is needed higher precision, and operation is also fairly simple.
Summary of the invention
The present invention is directed to the problems referred to above of the prior art, a kind of rocking arm hole milling positioner is provided, it is simple in structure, and is easy and simple to handle, and machining accuracy is high.
The technical solution adopted in the present invention is as follows:
Rocking arm hole milling positioner comprises left positioning seat and right positioning seat, and left positioning seat is L-shaped, and the side edge of the upper table surface of left positioning seat is with semi-circular groove, on the sidewall about the semi-circular groove symmetry with left circular hole; Be provided with adjusting device on the following table; The top edge of right positioning seat is with square breach, and the antetheca of right positioning seat and sidewall are respectively with right circular hole and square groove, and right circular hole is symmetrical about square breach; Bolt passes left circular hole and right circular hole connects as one right positioning seat and right positioning seat.
The invention has the advantages that: left and right sides positioning seat is set, and at each positioning seat breach and the semi-circular groove corresponding with rocking arm two ends difference are set, table top on left positioning seat arranges adjusting device for supporting rocking arm simultaneously, height that can adjusting rock arm, left and right sides positioning seat is bolted and is integrated, and rocking arm is carried out clamping and positioning; The present invention is simple in structure, and is easy and simple to handle, and machining accuracy is high.
Description of drawings
Fig. 1 is the stereogram of left positioning seat of the present invention.
Fig. 2 is the stereogram of right positioning seat of the present invention.
Fig. 3 is use state diagram of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1 to Figure 3, the present invention includes left positioning seat 1 and right positioning seat 2, left positioning seat 1 is L-shaped, and the side edge of the upper table surface 11 of left positioning seat 1 is with semi-circular groove 15, be used for the cylindrical end location with Rocker arm 4, on the sidewall of upper table surface 11 about semi-circular groove 15 symmetries with left circular hole 14; Be provided with adjusting device 13 on the following table 12, support Rocker arm 4 in vertical direction and regulate its height; End face 21 edges of right positioning seat 2 are with square breach 22, the square end of 22 pairs of Rocker arm 4s of square breach positions, the antetheca of right positioning seat 2 and sidewall are respectively with right circular hole 23 and square groove 24, left circular hole 14 on right circular hole 23 and the left positioning seat 1 is corresponding, right positioning seat 2 can be fixed with operating desk by square groove 24; Right circular hole 23 is about square breach 22 symmetries; Bolt 3 passes left circular hole 14 and right circular hole 23 connects as one right positioning seat 1 and right positioning seat 2, with the Rocker arm 4 clamping and positioning, mills out circular hole 41 at the end face of the cylindrical end of Rocker arm 4.
More than describing is explanation of the invention, is not that limited range of the present invention within protection scope of the present invention, can be done any type of modification referring to claim to the restriction of invention.
