Description

A marking hole drilling jig for plunger

technical field

The invention relates to a tooling fixture, in particular to a marking hole drilling fixture for a plunger.

Background technique

In order to distinguish the various models of the plunger parts, in the prior art, the marking holes are usually drilled on the plunger parts. Since the marking holes are arranged at intervals, in the prior art, after drilling a marking hole, the post is usually drilled. The plug moves a certain distance again to carry out the drilling of the next marking hole. This drilling method not only increases the labor intensity, but also greatly wastes time, takes time and effort, and affects the processing efficiency.

Contents of the invention

In view of the above-mentioned existing problems, the applicant has made researches and improvements, and provides a marking hole drilling jig for plunger parts, which effectively realizes the drilling of the marking holes in place at one time, and greatly improves the processing efficiency.

The technical scheme adopted in the present invention is as follows:

A marking hole drilling jig for a plunger, including a bottom plate, one end of a double-ended screw is screwed to the bottom plate, and the other end passes through the pressure plate and is screwed to a lock nut; it is located on one side of the double-ended screw, A top column is also installed on the bottom plate, and one end of the top column protrudes from the bottom plate and abuts against the pressure plate; the drill sleeve positioning plate is installed on one side of the bottom plate, and the drill sleeves arranged at intervals are placed on the drill through the bushing. In the sleeve positioning plate, a drilling hole is opened in the drill sleeve; a positioning block and a positioning seat are also fixed on the bottom plate.

Its further technical scheme is:

There is a V-shaped groove on the positioning block, and a positioning plate is fixedly connected to one end of the positioning block, and a positioning groove is also opened on the positioning plate, and the positioning groove is rectangular;

A positioning rod of the device runs through the positioning seat;

In the lower part of the pressing plate, a spring is also set on the outer periphery of the double-ended screw;

The drill sleeve positioning plate is rectangular;

A locking handle is also welded on the locking nut.

The beneficial effects of the present invention are as follows:

The present invention is simple in structure and easy to install. By clamping and locking the plunger parts, the arrangement of the positioning plate, positioning block and positioning rod can make the positioning of the plunger parts accurate. In the drill sleeve, the one-time processing of multiple marked holes is realized, which saves time and effort, greatly improves the processing efficiency, saves the production cost of the enterprise, avoids secondary clamping, and reduces the labor intensity of workers.

detailed description

The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

As shown in Figure 1 and Figure 2, a marking hole drilling jig for plunger parts includes a bottom plate 1, and one end of a double-ended screw 12 is screwed to the bottom plate 1 and locked by a nut (not shown in the figure) , the other end runs through the pressing plate 7 and is screwed to the locking nut 8, the locking nut 8 is welded to the locking handle 6, and the spring 11 is also set on the outer periphery of the double-ended screw rod 12 at the bottom of the pressing plate 7. Have groove 701 and waist-shaped hole 702 on pressing plate 7; Be positioned at the side of double-ended screw rod 12, also install top post 10 on bottom plate 1, one end of top post 10 stretches out bottom plate 1 and opens with pressing plate 7 Groove 701 abuts; drill sleeve positioning plate 3 is installed on one side of base plate 1, drill sleeves 9 arranged at intervals are installed in drill sleeve positioning plate 3 through bushing 14, and drill sleeve positioning plate 3 is rectangular. A drilling hole 901 is opened in the drill sleeve 9; a positioning block 2 and a positioning seat 4 are also fixed on the bottom plate 1, and the positioning seat 4 runs through the positioning rod 5 of the device. There is a V-shaped groove 201 on the positioning block 2, and one end of the positioning block 2 is also fixedly connected to the positioning plate 13. There is also a positioning groove 1301 on the positioning plate 13. The positioning groove 1301 and the flat position of the plunger can cooperate with each other. , the positioning groove 1301 is rectangular.

Concrete work process of the present invention is as follows:

As shown in Figure 1 and Figure 2, first put the plunger into the V-shaped groove 201 of the positioning block 2, and at the same time insert the flat position of the plunger into the positioning groove 1301 of the positioning plate 13, and then place one end of the plunger Abut against the positioning rod 5 of the positioning seat 4, the arrangement of the V-shaped groove 201 ensures the level of the plunger, and then the locking handle 6 drives the locking nut 8 to rotate at the end of the double-ended screw 12, so that the pressing plate 7 is lowered Press until one end of the pressure plate 7 contacts the outer circumference of the plunger. Due to the arrangement of the top column 10, the downward pressure of the pressure plate 7 remains horizontal. The arrangement of the spring 11 saves the adjustment process of the pressure plate 7. Finally, the force is applied through the lock The clamping nut 8 compresses the pressing plate 7 to ensure the fixing of the plunger, and then inserts the moving drill bit into the drilling hole 901 to realize the one-time processing of the marking hole of the plunger.

The above description is an explanation of the present invention, not a limitation of the invention. For the limited scope of the present invention, please refer to the claims. Within the protection scope of the present invention, any form of modification can be made.
