Abstract
An indexing jig of grouped radial holes of an excircle of a large tube workpiece is composed of a left template (1), a right template (2), upper templates (3), drill bushings (4 and 5), a bolt (6), a positioning screw (7), a draw bar (8), lifting bolts (9) and gaskets (10), wherein the left template and the right template are respectively installed at two ends of the large tube workpiece to be processed, and the left template and the right template clamp the workpiece through the draw bar; the upper templates are arranged on the lateral sides of the left template and the right template and are close to the excircle of the large tube workpiece; the drill bushings are installed on the upper templates; the lifting bolts for lifting the large tube workpiece with a jig clamp are installed on the left template and the right template; and the gaskets are installed at edges of the left template and the right template. The left template and the right template are polygonal plate-shaped parts, and the number of polygons depends on distribution of the radial holes on the circumferential surface of the workpiece. The indexing jig of the grouped radial holes of the excircle of the large tube workpiece is suitable for processing excircle holes of the large tube workpiece.
Description
Technical field
The utility model relates to the in groups indexing jig of radial hole of a kind of large cylinder excircle of workpiece, belongs to machining frock technical field.
Background technology
In actual production, tend to run on the large cylinder-shaped excircle of workpiece and hole, the radial hole on the machining large cylindrical shape cylindrical can bore processing at " V " type groove with the cylindrical workpiece lodging usually, if the hole on the cylindrical is to distribute with the cylinder vertical direction, and be distributed in groups the both sides of cylinder bus, and have more than the ten component degree, therefore, difficulty of processing this or similar large cylinder-shaped workpiece is then larger, drill bit easily bores partially, and accuracy is difficult to assurance, and production efficiency is low.
Summary of the invention
The purpose of this utility model is that in order to solve the in groups calibration boring problem of radial hole of large cylinder-shaped excircle of workpiece, the utility model discloses the in groups indexing jig anchor clamps of radial hole of a kind of large cylinder-shaped excircle of workpiece.
The technical solution of the utility model is that the utility model large cylinder excircle of workpiece in groups indexing jig of radial hole is comprised of left template, right template, cope match-plate pattern, drill bushing, latch, dog screw, pull bar, lifting bolt and cushion block; Left template and right template are installed in respectively the large cylinder-shaped workpiece two ends of waiing upon processing, by pull bar with left and right template clamp clamping of workpieces; The left and right template side that cope match-plate pattern is installed is near the cylindrical of large cylinder-shaped workpiece; Drill bushing is installed on the cope match-plate pattern; Dog screw is used for Template Location, and lifting bolt is installed on the left and right template, has been used for being lifted with the large cylinder-shaped workpiece of drilling jig gripper; Cushion block is installed in left and right template edge, for the protection of the unlikely wearing and tearing of left and right template.
Left and right template is the tabular parts of polygon, and polygonal quantity depends on the distribution of radial hole on the workpiece periphery, if radial hole to be processed is that then left and right template is quadrangle in circumferencial direction four hole equal distribution; If radial hole to be processed is that then left and right template is pentagon, by that analogy in circumferencial direction five hole equal distribution; The contact-making surface of left and right template and cylindrical workpiece end face is processed as fixing structure, i.e. seam and workpiece diameter interference fits on the left and right template plate face.
Cope match-plate pattern is installed in left and right template side, according to the demand of Workpiece boring the drill jig hole is set, and is equipped with drill bushing.
The beneficial effects of the utility model are, the large cylinder excircle of workpiece is after the utility model drill jig has been adopted in radial hole processing in groups, anchor clamps are simple and direct reliable, the required precision of design not only can be satisfied in the hole that processes, and easy to process, improve production efficiency, greatly alleviated workman's labour intensity.
The utility model be applicable to the large cylinder excircle of workpiece in groups radial hole calibration processing.

The specific embodiment
The specific embodiment of the present utility model is for the in the circumferential direction of the circle processing in equal distribution hole, 10 hole of large cylinder-shaped workpiece, and cylindrical drilling jig structure as shown in Figure 1.
The present embodiment cylindrical 10 hole equal distribution drill jigs are comprised of left template 1, right template 2, cope match-plate pattern 3, large drill bushing 4, bradawl cover 5, latch 6, dog screw 7, pull bar 8, lifting bolt 9, cushion block 10 and housing screw 11.Left template 1 and right template 2 are the platy structure of 10 limit shapes, as shown in Figure 4; The locating surface inner stopper structure vertical with workpiece left end plane of left template 1, as shown in Figure 5; The locating surface male half coupling structure vertical with workpiece right-hand member plane of right template 2, as shown in Figure 3.Be furnished with slotting Xiao hole, slotting Xiao 6 who is used for installing fixation workpiece in left template 1 and right template 2; Processed screw in left template 1 with right template 2 corresponding limits, cope match-plate pattern is mounted thereto; Cope match-plate pattern requires to be provided with the drill bushing of 8 macropores and several apertures according to workpiece; Also be provided with dog screw 7 and housing screw 11 on the cope match-plate pattern 3, as shown in Figure 6.
On left template 1 and right template 2, lifting bolt has been installed also, has been used for lifting drill jig and workpiece.In left template 1 and right template 2 every one side the cushion block of equal thickness has been installed all, has been avoided wearing and tearing around the left and right template and damaging, also can reduce contact-making surface.
