Description

a jig

【Technical field】

The utility model relates to a drilling mold, in particular to a drilling mold for drilling long pipes.

【Background technique】

In the prior art, the types of clamps for drilling machines are as follows: (1) Fixed drilling jigs—mainly used on vertical drilling machines or radial drills to process parallel hole systems, and the position of the jig jigs on the machine tool is fixed. (2) Rotary drilling jig - the drilling jig is equipped with an indexing device to process several axial or radial hole systems distributed around the axis on the workpiece. (3) Flip-type drilling mold-used to process holes on different surfaces of small workpieces, the hole diameter is less than φ8-φ10mm. It can reduce the number of installations, the drilling mold is turned over manually, and the fixture and workpiece are generally less than 10kg. (4) Cover plate type drilling template - the drilling template is clamped on the workpiece without clamping body. It is suitable for small hole processing on large and heavy workpieces. The quality of the drilling template is generally less than 10kg. The above drill model points are single, and if functions are added, then the efficiency will be reduced. Chinese patent literature discloses the general drill model of patent No. CN200420025138. There are at least two connecting blocks, the connecting blocks are arranged parallel to each other, and there is at least one positioning block. There is a through groove perpendicular to the connecting block, the drill sleeve is fixed on the slider, the slider is matched with the through groove, the slider can slide in the through groove, and the slider locking device is set on the positioning block . The utility model has versatility, but it is still inconvenient for long pipe drilling.

【Content of utility model】

The technical problem to be solved by the utility model is to provide a drilling jig so that the drilling jig can adapt to long pipes with many rotation angles.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical scheme: it includes a drill sleeve and a positioning block; it also includes a drill pipe, the center of which is a through hole, and the drill sleeve and the positioning block are fitted on the drill pipe superior.

The positioning block is cylindrical, and the middle part is a step hole connected with a tapered hole, and the tapered hole faces inwardly, and the outer circle is matched with the drilling mold pipe.

The clamping block is equipped on the drilling mold pipe.

The clamping blocks are two semicircular shapes, one half of which has two threaded holes and is installed on the drilling template pipe, and the other half has two through holes.

When the drill sleeve is a single hole, it is in the shape of a T-shaped cylinder.

When the drill sleeve has two holes, it is in the shape of a T-shaped elliptical column.

Due to the adoption of the above technical scheme, the utility model has the following beneficial effects: when the holes on the long pipe have many rotation angles, large batches, and high precision requirements for hole spacing, the drilling mold pipe can be supported by V-shaped blocks, and the drilling mold pipe can be rotated by hand And move until the drill bit is aligned with the hole of the drill sleeve, and then drill the hole after holding the drill pipe with your hand. If there are the same few holes, just repeat the above operation procedures. Because it is easy to assemble and disassemble, flexible to move, reliable to clamp, and can reduce the number of installations. Simple, convenient operation, quick action, short manufacturing cycle, low cost, and wide adaptability. In addition, because the tool setting is mainly dragged by hand during production, the drill sleeve is easy to wear.

Below in conjunction with accompanying drawing, the utility model is described in further detail.

【Detailed ways】

Please refer to Fig. 1 to Fig. 9, the utility model provides a drill bushing and a positioning block; also includes a drill pipe 1, the center of the drill pipe 1 is a through hole, and the drill bushing 3 and the positioning block 2 are assembled On the drill pipe 1.

The positioning block 2 is cylindrical, and the middle part is a step hole connected with a taper hole, and the taper hole is inwardly and externally matched with the drilling mold pipe 1 .

The clamping block 4 is fitted on the template pipe 1 .

The clamping blocks 4 are two semicircular shapes, one half of which has two threaded holes and is installed on the template pipe 1, and the other half has two through holes 5. ,

The drill sleeve 3 has a T-shaped cylindrical shape with a single hole, and a T-shaped elliptical cylindrical shape with double holes. The drill sleeve 3 is installed on the mold pipe 1. The positioning block 2 is installed on one end of the mold pipe 1, and the clamping block is installed on the other end. 4. The clamping block 4 is divided into two semicircles, one half of which is installed on the drill pipe, and the other semicircle is used for clamping and detachment.

The positioning block 2 is cylindrical, and the middle part is a step hole connected with a tapered hole, and the tapered hole is inwardly and externally matched with the drilling mold pipe 1 .
