For achieving the above object, technical solution of the present invention is: a kind of commutation drill jig, it T-shaped key comprising soleplate, positioning support, two and above V-shaped rest, support plate, two and above bushing plate, two and above pressing plate and match with the central channel that has on workpiece to be machined locating surface; Soleplate has the T-shaped groove in location; Positioning support is fixed on the left end of soleplate, its right side has the rectangular slot that can fixedly mount T-shaped key, the soleplate of its right-hand member is fixed with two and above V-shaped rest, the rectangular slot of positioning support and the centre of location of V-shaped rest are on the same axis; Before and after V-shaped rest, the T-shaped groove in the location of the soleplate of both sides is installed with respectively the fixed bar of two and above pressing plate and adjustable lever, two and above bushing plate and support plate; Pressing plate is fixed on adjustable lever away from the end winding support of workpiece to be machined at fixed bar and adjustment height, and during use, the other end is crimped on workpiece to be machined; Bushing plate upper end is provided with just to the drill bit of the processed position, hole of workpiece to be machined, and drill bit and processed bore dia match; Support plate upper end is provided with alignment pin, and it directly aims at the flat horizontal surface that left end withstands on the workpiece to be machined on positioning support.

The pressing plate other end described above is just in time positioned at the upper end of V-shaped rest, is fixedly clamped by workpiece to be machined together with V-shaped rest.

When using of the present invention, when holing in the position vertical with the central channel that locating surface has for workpiece to be machined, located by the T-shaped key be fixedly mounted in the rectangular slot of positioning support right-hand member, as long as workpiece to be machined is placed on V-shaped rest, left end central channel is through on T-shaped key, aimed at by pressing plate and compress, adjusted by drill bit, positive alignment can be holed by position, perforate hole; When holing with the flat vertical position on locating surface for workpiece to be machined, as long as workpiece to be machined is placed on V-shaped rest, left end withstands on positioning support right side, regulate support plate position, the flat horizontal surface that the alignment pin that its upper end is installed directly is crimped on workpiece to be machined can be holed.The present invention is when holing to same product, just can use as long as according to the size calculated the position of bushing plate, support plate and pressing plate adjusted in advance, when changing the product of another batch of different size, then row regulates the position of bushing plate, support plate and pressing plate, very easy to use.

In a word, the locating surfaces such as JL-10 outer tube front connector can be had central channel and the flat blank Workpiece clamping boring vertical with central channel by the present invention, simple to operate, machining accuracy is high, ensure that the quality of processing work, operating efficiency increases substantially, and improves more than 3 times.
