Abstract

The utility model discloses pneumatic drilling machines. The cylinders of the drilling machines are fastened on cylinder seats by screws, the cylinder seats are connected and fastened with material clamping seats by screws, the piston rods of the cylinders and the cylinder seats are connected and fixed by screw threads, pneumatic drills are fixed on the seats of the pneumatic drills by the upper clamps of the pneumatic drills and the lower clamps of the pneumatic drills through using screw rods, and pressure springs are penetrated between pressure rods and pressure sleeves and are assembled by using pin bolts; moreover, the pressure springs are upwards connected with the seats of the pneumatic drills and are downwards connected with material feeding clamps, material blanking clamps are fixed on the material clamping seats by using screws, the material clamping seats are connected with slideways by back sliding blocks and short sliding blocks, and the slideways are two parallel slideways; and moreover, the two parallel slideways are fixed on racks. The sizes of a plurality of drilling machines disclosed by the utility model are converted by the parallel slideways, and the drilling machines can be used for drilling out a plurality of holes on the same center line of a circular pipe. The pneumatic drilling machines have good drilling quality and high working efficiency and are simple to operate.

Description

Pneumatic drilling machine

Technical field

The utility model relates to a kind of punch device, especially a kind of pneumatic drilling machine.

Background technology

At present, like product is of a great variety on the market, still, punches on pipe and generally can only beat one by one, thereby exist the several holes of being beaten can accurately be in the problem on the center line.

The utility model content

At the deficiencies in the prior art, the purpose of this utility model is to provide a kind of can bore a plurality of holes simultaneously on pipe, and a plurality of holes of while are the pneumatic drilling machine on a center line again.

The utility model adopts following technical scheme to realize its purpose: a kind of pneumatic drilling machine, comprise cylinder and pneumatic drill two large divisions, it is characterized in that: cylinder is fastened on the cylinder block by screw, cylinder block is connected fastening by screw with the material folding seat, cylinder piston rod is fixing by being threaded with cylinder block, pneumatic drill presss from both sides down by folder and pneumatic drill on the pneumatic drill and is fixed on the pneumatic drill seat with screw rod, passing pressure spring between press rods and the pressure sleeve assembles with pin, and on connect the pneumatic drill seat, under connect feed collet, following feed collet is screwed on the material folding seat, the material folding seat is connected with slideway with short slide block by rear slider, slideway is two parallel slideways, and these two parallel slideways are fixed on the frame.

The beneficial effect that the technical scheme that adopts the utility model to provide can reach is: a plurality of rigs carry out the conversion of size by parallel slideway, can get out a plurality of holes on same center line of pipe.

Description of drawings

Fig. 1 is the utility model front view;

Fig. 2 is the utility model right view.

The specific embodiment

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

As depicted in figs. 1 and 2, be respectively the utility model front view and the utility model right view, a kind of pneumatic drilling machine, comprise cylinder 10 and pneumatic drill 5 two large divisions, wherein cylinder 10 is fastened on the cylinder block 11 by screw, cylinder block 11 is connected fastening by screw with material folding seat 12, cylinder 10 piston rods are fixing by being threaded with cylinder block 11, cylinder 10 is provided with cylinder air inlet pipe 1 and cylinder escape pipe 2, pneumatic drill 5 presss from both sides 6 usefulness screw rods down by folder 4 and pneumatic drill on the pneumatic drill and is fixed on the pneumatic drill seat 13, drill bit on the pneumatic drill 5 links to each other with last feed collet 8 by punching cover 7, pneumatic drill 5 is provided with pneumatic drill air inlet pipe 3, pass pressure spring 19 usefulness pins assemblings between press rods 17 and the pressure sleeve 18, and on connect pneumatic drill seat 13, connect feed collet 8 down, following feed collet 9 is screwed on material folding seat 12, material folding seat 12 is connected with slideway 15 with short slide block 20 by rear slider 14, and slideway 15 is two parallel slideways, and these two parallel slideways are fixed on the frame 16.

During use, the pipe that will hole is put between feed collet 8 and the following feed collet 9, the source of the gas that produces by air pump drives the action of cylinder 10 piston rods, driving feed collet 8 moves down, pressure spring between press rods 17 and the pressure sleeve 18 19 is as buffering simultaneously, make firm being fixed between feed collet 8 and the following feed collet 9 of workpiece (pipe), also driving takes offence bores 5 actions downwards to pneumatic drill seat 13 along with cylinder 10 piston rods move simultaneously, source of the gas is also driving the drill bit rotation on the pneumatic drill 5, overlap to getting out our needed circular hole on the workpiece (pipe) by the punching on the last feed collet 8, because be a plurality of pneumatic drill mechanisms and discharge a plurality of, reached a pneumatic work of control and can get the different circular hole of a plurality of distances at a pipe, the punching cover that can also change different-diameter as required and drill bit satisfy the processing request of different apertures pipe, having improved production efficiency aborning greatly, reduced working strength of workers, is that a kind of drilling quality is good, simple to operate, the pneumatic drilling machine of high efficiency.

Claims

1. pneumatic drilling machine, comprise cylinder and pneumatic drill two large divisions, it is characterized in that: cylinder is fastened on the cylinder block by screw, cylinder block is connected fastening by screw with the material folding seat, cylinder piston rod is fixing by being threaded with cylinder block, pneumatic drill presss from both sides down by folder and pneumatic drill on the pneumatic drill and is fixed on the pneumatic drill seat with screw rod, passing pressure spring between press rods and the pressure sleeve assembles with pin, and on connect the pneumatic drill seat, under connect feed collet, following feed collet is screwed on the material folding seat, and the material folding seat is connected with slideway with short slide block by rear slider.

2. according to the described pneumatic drilling machine of claim 1, it is characterized in that: slideway is two parallel slideways, and these two parallel slideways are fixed on the frame.
