It is worth mentioning that the lifting block 4 can shelter the opening of the processing cylinder 1 while descending for feeding, so that dust generated in the polishing process is prevented from flying through the opening of the processing cylinder 1, and an excellent processing environment is further ensured.
The lifting block 4 is fixedly connected with a fourth pipe 41 in a penetrating mode, the fourth pipe 41 and the main shaft 12 are connected in a penetrating and rotating mode through a bearing, one end of the fourth pipe 41 penetrates and extends into the driving cavity 5, the other end of the fourth pipe penetrates and extends into the processing cylinder 1, compressed air drives the main shaft 12 to rotate through the vortex impeller 7, the speed of the compressed air is reduced, dust generated by polishing the inner wall of the hollow pin can be directly blown out of the hollow pin through the ejection of the fourth pipe 41, and therefore cleaning of the inner wall of the hollow pin is completed while polishing is achieved, manual cleaning is avoided when subsequent processing is completed, and the labor intensity of subsequent processing is greatly reduced.
The first pressure release valve 32 is arranged in the first hole 29, the opening pressure of the first pressure release valve 32 is small, and the air which enters the annular cavity 28 from the hollow cavity can synchronously enter the first hole 29, so that the sliding block 30 synchronously slides, the axis of the clamped hollow pin is ensured to be consistent with the axis of the main shaft 12, and the machining precision is ensured.
Two second holes 43 are formed in the bottom wall of the processing cylinder 1, the second holes 43 are used for communicating the corresponding first holes 29 with the outside, a plurality of third holes 44 are formed in the annular plate 35, electromagnetic valves 45 are arranged in the second holes 43 and the third holes 44, the electromagnetic valves 45 are opened and closed along with the opening of the device, and therefore after the equipment is closed, the lifting block 4 and the sliding block 30 can be reset freely.
In the invention, a hollow pin to be processed is placed in a processing cylinder 1, a device is opened, an electromagnetic valve 45 is synchronously closed, a second hole 43 and a third hole 44 are closed, compressed air firstly enters an annular cavity 28, compressed air entering the annular cavity 28 firstly causes a first pressure relief valve 32 to be opened, at the moment, air enters a first hole 29, a slide block 30 drives a clamping block 31 to clamp the hollow pin, after clamping is completed, along with the increase of clamping force, the pressure in the annular cavity 29 is continuously increased until the pressure is increased to the opening value of a second pressure relief valve 34, and the second pressure relief valve 34 is opened.
At this time, air enters the annular block 2 through the first pipe 33, so that the annular plate 35 slides downwards, the lifting block 4 is driven to descend through the sliding column 3, so that the main shaft 12 is inserted into the clamped hollow pin, and when the lifting block 4 descends to the lowest position, the pressure in the annular block 2 is continuously increased at this time until the opening value of the third pressure relief valve 38 is reached, and then the third pressure relief valve 38 is opened.
After the third pressure release valve 38 is opened, compressed air enters the driving cavity 5 through the hose 40 and the third pipe 39, the blades of the vortex impeller 7 are impacted by the compressed air, so that the vortex impeller 7 rotates to drive the main shaft 12 to rotate, the rotation of the main shaft 12 drives the first gear 11 to rotate, the second gear 10 rotates around the main shaft 12 while the first gear 11 rotates through the meshing of the first gear 11, the second gear 10 and the gear ring 13, the main shaft 12 drives the polishing block 17 to rotate to polish the inner wall of the hollow pin, and the auxiliary shaft 9 drives the polishing roller 18 to polish the outer wall of the hollow pin.
In the polishing process, since the polishing block 17 and the polishing roller 18 are respectively and fixedly connected with the first pressing block 15 and the second pressing block 20, the resistance of the polishing block 17 and the polishing roller 18 in the polishing process is directly applied to the first force-sensitive resistor 16 and the second force-sensitive resistor 21 through the first pressing block 15 and the second pressing block 20, so that the resistance of the first force-sensitive resistor 16 and the second force-sensitive resistor 21 is changed, and when the polishing is complete, the resistance between the polishing block 17 and the polishing roller 18 and the hollow pin is larger, so that the pressure of the first force-sensitive resistor 16 and the second force-sensitive resistor 21 is larger, so that the resistance of the first force-sensitive resistor 16 and the second force-sensitive resistor 21 is smaller, and the magnetic force of the electromagnet 23 can not trigger the control button 25 by the permanent magnet 26.
When polishing is completed, the friction force between the polishing block 17 and the polishing roller 19 and the hollow pin is reduced, so that the pressure applied to the first force sensitive resistor 16 and the second force sensitive resistor 21 is reduced, and when the pressure applied to the first force sensitive resistor 16 and the second force sensitive resistor 21 is reduced, the resistance is increased, so that the magnetic force of the electromagnet 23 is reduced, and the permanent magnet 26 is contacted with the control button 25 under the elastic force of the first spring 27, so that the device is stopped, namely, the device is automatically stopped after polishing is completed.
When polishing, compressed air enters the driving cavity 5 to drive the vortex impeller 7 to rotate for polishing, most of energy of the compressed air is converted into kinetic energy for driving the vortex impeller 7 to rotate, so that the speed of the compressed air is greatly reduced, the compressed air after speed reduction is sprayed out through the fourth pipe 41 and sprayed into the hollow pin, dust generated after the inner wall is polished is blown out, and the inner wall of the hollow pin is required to be cleaned after the follow-up processing is completed.
After the machining is stopped, the electromagnetic valve 45 is opened, at this time, under the elasticity of the second spring 36, the annular plate 35 is reset, so that the lifting block 4 is lifted, meanwhile, the clamping of the hollow pin is released by the clamping block 31, the polished hollow pin is taken out, the hollow pin to be machined next is put into, and the machining is continued according to the steps.
The invention can make the whole device operate by only driving one air source without arranging additional driving equipment, so that the structure of the whole device is more compact, and the operation and maintenance cost of the equipment is lower while ensuring higher operation efficiency.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
