The pipeline joint is provided with a switch.
The technical scheme provided by the invention has the beneficial effects that:
(1) the pneumatic grinder is simple in structure and is directly mounted on a numerical control lathe to grind or polish the bearing position of the large-specification impeller rotor. Saves a large amount of time for carrying, clamping and adjusting the alignment of workpieces and reduces the production cost.
(2) The machine has multiple functions, saves the equipment purchasing cost and reduces the equipment investment of companies.
(3) And the workpiece is aligned by one-time clamping without secondary clamping, so that the reserved finish machining allowance is smaller, and the working efficiency is greatly improved.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1-2, a feeder bushing inner bore grinding device comprises a chuck 1, four claws 2, a clamping bushing 3, a strong abrasive belt 4, a tensioning frame 5, a clamping block 6, a pneumatic motor 7, a switch 8, a pipeline joint 9, a strong cutter bar 10, a cutter pressing bolt 11 and a machine tool rest 12, wherein the chuck 1 and the four claws 2 are mounted on a lathe spindle, the clamping bushing 3 is clamped and fixed by the four claws 2, the clamping bushing 3 is driven by the lathe spindle to rotate (50-60r/min), the strong abrasive belt 4 is mounted on a hard rubber wheel 13 and tensioned by a tensioning wheel 14 to run at a high speed (6000r/min), the pneumatic motor 7 is driven by the pneumatic motor 7 (0.5-0.6 mpa pressure gas), the tensioning frame 5 realizes tensioning of the strong abrasive belt 4, the pneumatic motor 7 is clamped by the clamping block 6 and connected to the strong cutter bar 10 by the cutter pressing bolt 11, the powerful cutter bar 10 is fixedly connected with a cutter pressing bolt 11 on a cutter rest of a machine tool, and the pipeline joint 9 is connected with an air source.
And a switch 8 is arranged on the pipeline joint 9.
The working principle is as follows:
1) the feeder clamping bush 3 is clamped on a numerically controlled lathe by a tool, and is driven by a lathe spindle to rotate (the rotating speed is 50-60 r/min). A large rotary diameter (850mm) is arranged above a middle supporting plate of the numerical control lathe, and the lathe is started to realize the rotary motion of the clamping bush 3 of the large-specification feeder.
2) The pneumatic grinder is provided with a strong abrasive belt 4 driven by a pneumatic motor 7, and the pneumatic motor 7 drives the strong abrasive belt 4 to move at high speed (6000r/min) by using pressure gas of 0.5-0.6 MPa for grinding or polishing.
3) The powerful cutter bar 10 is arranged on a cutter rest 12 of a machine tool (the cutter rest is arranged on a middle supporting plate of the machine tool) and is pressed tightly by a cutter pressing bolt 11, so that deep hole machining is realized.
4) The pneumatic grinder is arranged on a powerful cutter bar 10 and is pressed tightly by a clamping block 6 and a cutter pressing bolt 11. Axial and radial movement is realized, and the pneumatic grinding machine can flexibly grind or polish. Finally, the grinding machining precision of the feeder bushing meets the design requirement.
