Abstract

The invention discloses an up-down concentric drilling fixture, which solves the problem of low processing precision by turning a workpiece and processing a pin hole at the other end through tooth positioning. The up-down concentric drilling fixture consists of a bottom plate (1), an inner hexagon screw (2), a floating positioner (3), an auxiliary positioning spindle (4), an open washer (5) and a hexagon bolt (6), wherein the lower end of the auxiliary positioning spindle (4) is pressed on the bottom plate (1), and a screwed hole is formed in the centre of the upper end; the hexagon bolt (6) passes through the open washer (5) and is screwed in the screwed hole; the floating positioner (3) is fixed on the bottom plate (1) through the inner hexagon screw; a workpiece (7) is mounted on the auxiliary positioning spindle (4), the end with the pin hole facing downwards; a positioning taper pin of the floating positioner (3) is inserted into the pin hole of the workpiece (7) and positioned to fasten the workpiece (7); and the pin holes (9) at the two ends are processed. The invention has the advantages of simple structure, convenient operation and high processing precision.

Description

Concentric up and down drill jig
Technical field
The present invention relates to the machining anchor clamps, be specifically related to a kind of concentric up and down drill jig.
Background technology
There is dowel hole at heavy-duty car bent axle backgear workpiece two ends, require two pin-and-holes concentric, and dowel hole and tooth have the requirement of timing angle.Conventional processing method is on numerical control drilling machine, process an end pin-and-hole earlier with the tooth location after, again with tooth location processing other end pin-and-hole, machining accuracy is low, does not reach the product quality requirement with the workpiece upset.
Summary of the invention
The present invention discloses a kind of concentric up and down drill jig, and the above-mentioned technical problem so that solution exists reaches quality requirement.
The present invention adopts following scheme for achieving the above object: the drill jig anchor clamps are made up of base plate (1), soket head cap screw (2), float locator (3), assist location axle (4), open washer (5) and hex bolts (6) six parts with one heart up and down; Wherein assist location axle (4) lower end is fitted on the base plate (1), and there is screwed hole at the center, upper end, and hex bolts (6) passes open washer (5) and is screwed in the screwed hole; The locator (3) that floats is fixed on the base plate (1) by soket head cap screw, and the locating cone pin center of locator (3) upper end of floating is parallel with the center line of assist location axle (4) and apart from being the theoretical right value of the last two pin-and-hole centre-to-centre spacing of workpiece (7).
The present invention is helpful to be: simple in structure, be convenient to operation, machining accuracy height.
Description of drawings
The invention will be further described below in conjunction with the drawings and specific embodiments.
Fig. 1 is concentric up and down drill jig cutaway view.
Among the figure: base plate 1, soket head cap screw 2, unsteady locator 3, assist location axle 4, open washer 5, hex nut 6, workpiece 7.
The specific embodiment
As shown in Figure 1, concentric up and down drill jig is made up of base plate 1, hexagon socket head cap screw 2, the locator 3 that floats, assist location axle 4, open washer 5, hex bolts 6.Wherein assist location axle 4 lower ends are fitted on the base plate 1, and there is screwed hole at the center, upper end, and hex bolts 6 is screwed in the screwed hole, so that workpiece loading and unloading; The locator 3 that floats fixes on the base plate 1 by soket head cap screw 2, and the locating cone pin center of locator 3 upper ends that guarantee to float is parallel with the center line of assist location axle 4 and apart from being the theoretical right value of pin-and-hole centre-to-centre spacing on the workpiece 7.
The course of work: at first concentric up and down drill jig is fixed on the workbench of numerical control drilling machine, adjusts machine tool program, the center of circle, location of the unsteady locator 3 of centering is set to the origin of coordinates; Manufactured workpiece 7 of one end pin-and-hole and assist location axle 4 are wiped clean, workpiece 7 is installed in assist location axle 4, the end that pin-and-hole arranged down, the location taper pin of unsteady locator 3 inserts the interior location of pin-and-hole of workpiece 7, put open washer 5, tighten hex nut 6 fastening workpiece 7, start the pin-and-hole of machine tooling two ends, guarantee that the two ends pin-and-hole is concentric.
Unclamp nut 6 after first workpiece 7 processing, take out open washer 5 and workpiece 7, anchor clamps are cleaned out, carry out next workpiece processing again.

Claims (2)

1. concentric drill jig up and down is characterized in that: described up and down with one heart the drill jig anchor clamps form by base plate (1), soket head cap screw (2), float locator (3), assist location axle (4), open washer (5) and hex bolts (6) six parts; Wherein assist location axle (4) lower end is fitted on the base plate (1), and there is screwed hole at the center, upper end, and hex bolts (6) passes open washer (5) and is screwed in the screwed hole; The locator (3) that floats is fixed on the base plate (1) by soket head cap screw.
2. according to the described concentric drill jig up and down of claim 1, it is characterized in that: the locating cone pin center of described unsteady locator (3) upper end is parallel with the center line of assist location axle (4) and apart from being the theoretical right value of the last two pin-and-hole centre-to-centre spacing of workpiece (7).
