Description

The mould that is used for processing belt cross bore axle class

Technical field

The utility model relates to a kind of mould, relates to a kind of mould that is used for processing belt cross bore axle class specifically.

Background technology

At present, the two ends of a lot of axles all have cross bore, and are like the main shaft of mine winch, as shown in Figure 1; The axle of this band cross bore is to adopt V shape iron 101 that axle 102 is carried out clamping adding man-hour, and the symmetrical center line on 101 liang of inclined-planes of axis and V shape iron of drill bit 103 is overlapped, and has refilled the pressing plate 104 of fixation; After having bored first hole, unclamp pressing plate, the anglec of rotation; Find the position in another hole accurately by the position of line, clamping platen bores second hole again.The each clamping of this processing mode can only bore a hole, and production efficiency is low, and positioning accuracy is not high.

The utility model content

The purpose of the utility model is to provide a kind of mould that is used for processing belt cross bore axle class, and clamping of this mould can bore two axial different holes simultaneously.

For realizing above-mentioned purpose; The utility model has adopted following technical scheme: comprise base, base is provided with the cylindrical shell that holds axle to be processed, and described base and cylindrical shell are square; Be respectively equipped with first, second boring on the adjacent both ends of the surface of cylindrical shell; First, second boring be staggeredly located out and axis perpendicular, the axis of first, second boring matches with the center line of axle horizontal direction to be processed and vertical respectively, also is provided with the fastener of fixing axle to be processed on the cylindrical shell.

The fastener of the utility model comprises the screw that matches with thumb screw on thumb screw and the cylindrical shell, and thumb screw is positioned at the end of cylindrical shell and the outer surface of axle to be processed leans.

The base of the utility model is provided with locating piece; Locating piece is stepped; Be made up of first locating piece of enlarged diameter section and second locating piece of reduced diameter section, wherein, second locating piece is fixed in the base; First locating piece is positioned at cylindrical shell, and the end face of the end face of first locating piece and axle to be processed leans.

The utility model and cylindrical shell are provided with on corresponding two other end face of both ends of the surface of first, second boring and are respectively equipped with first, second through hole, and the aperture of first, second through hole is greater than the aperture of first, second boring.

Be respectively equipped with first, second drill bushing in first, second boring of the utility model.

Link to each other through screw between the base of the utility model and the cylindrical shell.

Can know that by technique scheme the utility model is fixed axle clamping to be processed through fastener through axle to be processed is put into square cylinder again; Hole of subdrilling; The cylindrical shell that overturns then bores the another one hole again, realizes that with this axle is carried out a clamping can bore two holes simultaneously; Improved operating efficiency, and positioning accuracy is higher than traditional line mode.

Description of drawings

Fig. 1 is the mould structure sketch map in the background technology;

Fig. 2 is the front view of the utility model;

Fig. 3 is the A-A cutaway view of Fig. 2.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further specified:

Like Fig. 2, a kind of mould that is used for processing belt cross bore axle class shown in Figure 3; Comprise base 1; Base 1 is provided with the cylindrical shell 3 that holds axle 2 to be processed; Link to each other through screw 10 between base 1 and the cylindrical shell 3, it is square that base 1 and cylindrical shell 3 are, and is respectively equipped with first,

second boring

4,5 on the adjacent both ends of the surface of cylindrical shell 3; Be respectively equipped with first, second drill bushing 41,51 in first, second boring 4,5; First, second boring 4,5 be staggeredly located out and axis perpendicular, first, second boring axis of 4,5 matches with the center line of axle 2 horizontal directions to be processed with vertical respectively, also is provided with fixing to be processed 2 fastener on the cylindrical shell 3; Fastener comprises the screw that matches with thumb screw on thumb screw 6 and the cylindrical shell 3 specifically, and thumb screw 6 is positioned at the end of cylindrical shell 3 and the outer surface of axle 2 to be processed leans.

As the preferred version of the utility model, base 1 is provided with locating piece 7, and locating piece 7 is stepped; Be made up of first locating piece 71 of enlarged diameter section and second locating piece 72 of reduced diameter section, wherein, second locating piece 72 is fixed in the base 1; First locating piece 71 is positioned at cylindrical shell 3; And the end face of the end face of first locating piece 71 and axle 2 to be processed leans, and the effect that locating piece is set is the position of locating hole more accurately, does not need traditional crossed process.

Preferred version as the utility model; Be provided with on first, second boring corresponding two other end face of both ends of the surface of 4,5 with cylindrical shell 3 and be respectively equipped with first, second through

hole

8,9; The aperture of first, second through

hole

8,9 is greater than the aperture of first, second boring 4,5; First, second through

hole

8,9 is equivalent to an anti-dandruff hole in fact; Being that the chad that first, second boring gets out in 4,5 can fall through first, second through

hole

8,9, so the aperture of first, second through

hole

8,9 is bigger, also is falling of chad for ease.

Specific operation process is following:

Earlier axle 2 to be processed is inserted in the cylindrical shell 3, the end and the locating piece of axle 3 to be processed lean, simultaneously with thumb screw 6 lockings; Drill bit bores downwards from first boring 4, and it is good afterwards again with cylindrical shell 3 upsets to bore, and bores downwards from second boring 5 again; The chad that gets out falls through first, second through

hole

8,9 respectively; Like this axle is realized a clamping, just can on axle 2 to be processed, get out two perpendicular holes of axis, just usually said cross bore.

Above-described embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that those of ordinary skills make the technical scheme of the utility model all should fall in the definite protection domain of the utility model claims.
