Abstract
The utility model relates to a pneumatic grinding device, comprising a shell, a gas-guide bit, an air-guide parcel, a bearing backlash, a main axis, an air cylinder, a collet, a collet connecting bar and a collet cap. The air-guide parcel is connected with the bearing backslash by a positioning stud and the upper is respectively provided with an air filling channel and an air discharging channel. The wall of the air cylinder is respectively communicated with an air filling channel and an air inlet, an air filling cavity and air discharging cavity of the air discharging channel and the air outlet. One end of the main axis is positioned in the bearing of the bearing backslash while the other end is connected with the internal collet connecting bar with an external collet cap. The utility model overcomes the drawbacks of large volume, narrow applicable range and low reliability and safety and has the advantages of compacted structure, minor volume, easy and convenient operation, large applicable range and high effectiveness, thus the utilty model is a strongly reliable and environment-friendly product.
Description
The utility model relates to a kind of pneumatic mill engraving device.
The mill engraving device is widely used in the burr reconditioning of mould manufacturing, the processing and other fields of hand work product, and relatively more commonly used is the electronic grinding machine that hangs, but the volume of this instrument is big, the assurance effort, is not suitable for narrow and small deep hole is ground the operation at quarter; Phenomenon such as occur easily also in the course of the work simultaneously that motor burns out, electric leakage, flexible axle fracture.
The purpose of this utility model be solve that existing mill engraving device volume is big, narrow application range, reliability and the lower problem of security performance.The utility model comprises housing, guide head, air guide block, the bearing back seat, main shaft, cylinder, chuck, chuck connecting rod and chuck cover, air guide block links to each other by alignment pin with the bearing back seat, air inlet runner and grate flow channel are set respectively on it simultaneously, be respectively equipped with air admission hole and steam vent on the cylinder wall, main shaft is provided with flexible blade, and off-centre is assemblied in the cylinder in the lump, form between cylinder and the housing and be communicated with air inlet runner and air admission hole respectively, the inlet chamber of grate flow channel and steam vent and discharge chamber, one end of main shaft is positioned in the interior bearing of bearing back seat, the other end connects the chuck connecting rod of built-in chuck, the chuck connecting rod chuck cover that is spirally connected outward.
The utility model utilizes air compressor machine to be power source by above-mentioned specific design, has dwindled overall volume greatly, has compact conformation, easy for operation, applied widely, advantage that efficient is high, is a kind of environmentally friendly machine of good reliability.
Below in conjunction with drawings and Examples detailed content of the present utility model is described.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a sequential deployment schematic diagram of the present utility model;
Fig. 3 is the structural representation of cylinder;
Fig. 4 is the structural representation of air guide block.
As shown in the figure, the utility model comprises housing 1, guide head 2, air guide block 3, bearing back seat 4, main shaft 5, cylinder 6, chuck 7, chuck connecting rod 8 and chuck cover 9, air guide block 3 links to each other by alignment pin 18 with bearing back seat 4, air inlet runner 12 and grate flow channel 13 are set respectively on it simultaneously, be respectively equipped with air admission hole 14 and steam vent 15 on cylinder 6 walls, main shaft 5 is provided with flexible blade 10, and off-centre is assemblied in the cylinder 6 in the lump, form between cylinder 6 and the housing 1 and be communicated with air inlet runner 12 and air admission hole 14 respectively, the inlet chamber 16 of grate flow channel 13 and steam vent 15 and discharge chamber 17, one end of main shaft 5 is positioned in the bearing 11 in the bearing back seat 4, the other end connects the chuck connecting rod 8 of built-in chuck 7, the outer chuck covers 9 that are spirally connected of chuck connecting rod 8, the chuck connecting rod 8 outer housing 1 one ends protecgulum 19 that is spirally connected.Under user mode, the gases at high pressure that enter by guide head 2 enter inlet chamber 16 behind air inlet runner 12, flexible blade 10 and the main shaft 5 that drives in the cylinder 6 by air admission hole 14 rotates again, be fixed on the workpiece work on the chuck 7, and the gas after the work is discharged through steam vent 15, discharge chamber 17 and grate flow channel 13, the circulation of finishing the work.
