The energy-saving pneumatic polishing machine is on the basis of an original polishing machine, the position of air inlet hole of an original cylinder, which is positioned on the cylinder wall, is drilled with an air inlet through hole along the cylinder wall which is perpendicular to the direction of the central axis of the cylinder in the radial direction, the position of the air inlet through hole is provided with an air duct along the cylinder innerwall, the air inlet hole, the air inlet through hole and the air duct form an air inlet passage to be used as an air inlet main passage of compressed air, an original upper air guide hole and an original lower air guide hole are used as auxiliary air inlet passages, and the compressed air directly enters the main passage to push a sliding blade and a turning wheel to drive a crankshaft to rotate at high speed. The utility model adopts the design that the direct air suction and the air suction of the auxiliary upper and lower air guiding are combined, thereby reducing the energy loss of the compressed air and achieving the purposes of high efficiency and energy saving.
Description
Technical field
The utility model belongs to the pneumatic tool technical field, is specifically related to a kind of energy-efficient novel pneumatic polishing machine.
Background technology
Pneumatic polisher is a kind of polishing mechanical of pneumatic polishing of extensive use, and its critical piece is sliding blade group and the runner in cylinder and the cylinder block.During polishing machine work, compressed air promotes blade in cylinder block, makes runner drive the bent axle friction plate and runs up, and contacts with workpiece with the friction plate that rotates and polishes, polishes, and friction plate is commonly called as grinding wheel.
Existing pneumatic polisher all adopts compressed air in cylinder block gas port air inlet up and down, and promotion vane group, runner rotate at a high speed, and compressed air is discharged by the cylinder block steam vent, goes round and begins again and carries out work.Because gas port forms the air inlet of fourth type in the cylinder block, air inlet resistance in gas port is big, loss compressed air energy, thereby cause air inflow big, rotating speed is low, power reduction reduces the physical life of polishing machine.
Pneumatic polisher structural principle: the runner that has chute is installed on the bent axle, sliding blade places chute, eccentric is installed in the cylinder, compressed air is by the cylinder block inlet and outlet, promote sliding blade, the friction plate (being commonly called as grinding wheel) that makes runner drive bent axle and be loaded on the bent axle rotates at a high speed, and polishing machine runs well, and the friction plate of rotation elder generation contact workpiece carries out sanding and polishing at a high speed.
Summary of the invention
In order to increase work efficiency, reduce gas consumption, it is a kind of efficient that the utility model provides, and energy-conservation pneumatic polisher, this polishing machine adopt direct air inlet and the design that combines of air guide additional-air inlet up and down, reduce the compressed air energy loss, reach efficiently purpose of energy saving.
The technical scheme that its technical problem that solves the utility model adopts is: based on original pneumatic polisher, its cylinder is improved, promptly (this air admission hole is on cylinder wall in original cylinder intake hole, vertical with central axis of air cylinder) position, radially the direction of central axis of air cylinder (promptly perpendicular to) bores an air inlet through hole on cylinder wall, and in air inlet through hole exit, radially open an air drain (this air drain direction is vertical with the cylinder axis direction of principal axis) along cylinder inner wall, air admission hole, the air inlet through hole, air drain forms inlet channel, become compressed air air inlet main channel, on original, following gas port (parallel with central axis of air cylinder) is an auxiliary air inlet channel, and compressed air directly rotates at a high speed from main channel air inlet promotion sliding blade and runner drive bent axle.
In the utility model, the diameter of air inlet through hole is 1-3mm.The air drain width that is communicated with the air inlet through hole is 2-4mm greater than the diameter of air inlet through hole, and length is 10-15mm.
The utility model compared with prior art has following advantage:
1, idler revolutions are higher than original prototype
2, the idle running air consumption is less than original prototype
3, the rotating speed during peak power is higher than original prototype
4, the moment of torsion during peak power is higher than original prototype
5, peak power is higher than original prototype
6, the load air consumption is less than original prototype

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
General structure of the present utility model as shown in Figure 3.It is by bent axle 1, bearing 2,7,13, and interior thin jump ring 5, shell ladder 6, outer jump ring 12, O type sealing gland 8,9, cylinder 10, sliding blade 11, upper cover 14, following capping 17, fan blade runner 15, oversheath 16, and parts such as transmission screw are formed.In former polishing machine, establish upper and lower penetrating gas port 22 and air admission hole 21 on the cylinder 10.Improvements of the present utility model just are, at cylinder wall air admission hole 21 places, radially get out an air inlet through hole 19, at cylinder inner wall, exit one side of air inlet through hole 19 is along the rotation direction of sliding blade, open an air inlet duct 20, the width of this air inlet duct 20 is slightly larger than the diameter of air inlet through hole 19.With a certain model machine is example, and the internal diameter of former cylinder 10 is 40mm, highly is 20mm, the diameter of air admission hole 21 is 5mm, and the diameter of gas port 22 is 3.2mm, and the diameter of the air inlet through hole of newly opening 19 is 2.5mm, the air inlet duct width of cylinder inner wall is 3mm, and length is 12mm, and the degree of depth is 1-2mm.Like this, form main inlet channel by air admission hole 21, air inlet through hole 19 and air inlet duct 20, form the air inlet accessory channel, make compressed air directly from the main channel air inlet by air admission hole 21, gas port 22, promote sliding blade and runner drive bent axle and rotate at a high speed, reach the desired result of efficient energy-saving.The relevant performance indications of the polishing agent after the improvement are compared with original prototype, and are specific as follows:
