Description

Drill clamp for machining space pipe fitting

Technical Field

The utility model relates to the technical field of machining, specifically a drill clamp for space pipe fitting processing.

Background

The space three-dimensional pipe fittings on the engine are many, such as: the air inlet bent pipe, the air outlet bent pipe, the water outlet pipe, the connecting pipe and the like are difficult to process and adjust, and the adjustment is not timely, so that the assembly interference is often caused. With the development of engine technology, the spatial layout of the engine is more compact, and the requirements for the products are higher and higher.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a drill clamp convenient to adjustment to overcome the big, changeable problem of direction of variation that space pipe fitting blank face location caused, make the adjustment of processing space pipe fitting drill clamp very high-efficient.

The utility model discloses a realize that the technical scheme that above-mentioned purpose adopted is: the utility model provides a drill chuck for space pipe fitting processing, includes bottom plate (7) and connects terminal surface locating piece spare (8), fixed location V type piece (6), adjustable location V type piece (2) fixed work piece (1) on the bottom plate, puts pressure point supporting (5) at work piece pressure point position, adjustable location V type piece (2) are through adjusting screw (10) and connect holding screw (9) and angle backing plate (11) on bottom plate (7), pressure point supporting (5) are through adjusting screw (10) and connect holding screw (9) on bottom plate (7). The bottom plate (7) is also fixed with a turnover drilling template (4).

The workpiece (1) (shown in fig. 1) is positioned; then the opening pressing plate (3) presses the workpiece, the opening of the opening is just away from the umbilical, and the pressing point support (5) is added considering that the workpiece is deformed due to the suspension of the pressing point. The pipe fitting is positioned by using the fixed positioning V-shaped block (6), the problem caused by diameter variation can be solved, and the center of the pipe fitting can be confirmed by the V-shaped block no matter the diameter is increased or decreased. An adjustable positioning V-shaped block (2) is used for eliminating the size variation of the relative position of the pipe orifice.

Wherein, the vertical adjustment of the adjustable positioning V-shaped block (2) can be adjusted by the height of the adjusting screw (10); the fine adjustment in other directions can be realized by the clearance of the tightening screw (9), and if the clearance is too large, the fine adjustment can be realized by grinding the angle backing plate (11).

The principle of the pressure point support (5) and the adjustable positioning V-shaped block (2) are that the pipe orifice is horizontal on the pressure point support, so that the pipe orifice deterioration can only change in the height direction, and only an adjusting screw (10) is designed, and an angle cushion plate is not designed.

The batch size of this product varies widely, sometimes thousands of pieces, sometimes only tens of pieces, so considering the versatility on vertical machining centers and rocker drills, an inverted drilling template (4) is designed. When the batch is small, the drill plate can be put down, and the fixture is used on the rocker drill to relieve the insufficient pressure of the machining center; when the batch size is large, the drill plate can be turned over, and the fixture is used in a vertical machining center, so that the advantage of vertical machining speed is brought into play.

The utility model has the advantages that: the utility model discloses solved two problems of work piece size variation big, the troublesome these of anchor clamps adjustment well, according to the change of every batch of blank, will accomplish the adjustment of anchor clamps within an hour. In addition, the clamp can be used in a vertical machining center or a rocker arm drilling machine.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 2-6, a drill clamp for machining a space pipe fitting comprises a bottom plate 7, an end face positioning block 8 connected to the bottom plate, a fixed positioning V-shaped block 6, an adjustable positioning V-shaped block 2 for fixing a workpiece 1, a pressure point support 5 arranged at a pressure point position of the workpiece, wherein the adjustable positioning V-shaped block 2 is connected to the bottom plate 7 through an adjusting screw 10, a fastening screw 9 and an angle backing plate 11, and the pressure point support 5 is connected to the bottom plate 7 through the adjusting screw 10 and the fastening screw 9. The bottom plate 7 is also fixed with a turnover drilling template 4.

The workpiece 1 (shown in fig. 1) is positioned; then the opening pressing plate 3 presses the workpiece, the opening of the opening presses the umbilical open, and the pressing point support 5 is added considering that the workpiece is deformed due to the suspension of the pressing point.
