The branch 27 is provided with a valve 28 for opening or closing the branch 27. In normal operation, valve 28 is normally open; when commissioning or non-operation is required, the valve 28 is closed to prevent gas leakage.
The triplet 20 is provided for pressure stabilization and cleaning purposes. The energy accumulator 23 can play a role in constant-pressure grinding, and meanwhile, the energy accumulator 23 can also prevent other air pressure elements in the air path system from being impacted due to vibration of the piston rod 13 in the grinding process, so that the effects of absorbing and buffering impact and protecting other elements are achieved. By adjusting the pressure reducing valve 21, the pressure of the gas input into the cylinder 12 can be regulated, and reasonable pressure is selected according to the size of the workpiece and the change of the grinding dosage in the grinding process, namely, the piston rod 13 outputs reasonable thrust, so that the grinding quality and efficiency are improved.
The working process of the cylindrical grinding machine provided by the embodiment is as follows:
before grinding, the workpiece is first held by the headstock 2 and tailstock 3. Then the sliding platform 6 is driven to move forwards through the linear motor 8, and then the grinding wheel frame 5 on the sliding platform is driven to move forwards, so that the grinding wheel 4 on the grinding wheel frame 5 is close to a workpiece. The carriage 5 is then adjusted to be in the initial position on the sliding platform 6, specifically operating: the cylinder 12 is started, so that the grinding carriage 5 moves forwards along the second guide rail 9 until the limiting plate 16 at the rear end of the grinding carriage 5 is attached to the rear end face of the sliding platform 6, at the moment, the front end of the piston rod 13 of the cylinder 12 just abuts against the resisting surface 15 of the grinding carriage 5, and the grinding wheel 4 on the grinding carriage 5 just attaches to a workpiece. Then, the pressure reducing valve 21 in the pneumatic system circuit is adjusted so that the piston rod 13 of the cylinder 12 outputs an appropriate thrust.
During the rough grinding process, the grinding wheel 4 moves along the surface morphology of the workpiece due to the large surface roughness of the workpiece and the existence of protruding points on the surface of the workpiece, so that the grinding wheel 4 can float back and forth. In the process, when the grinding wheel 4 meets the salient points on the surface of the workpiece, the workpiece pushes the grinding wheel 4 to retreat, the grinding wheel frame 5 pushes the piston rod 13 of the air cylinder 12 to retract, the air in the left cavity of the air cylinder 12 is compressed, the pressure is increased, and the redundant air in the left cavity of the air cylinder 12 is pushed into and stored in the energy accumulator 23; when the grinding wheel 4 is separated from the salient points on the surface of the workpiece, the thrust of the salient points on the grinding wheel 4 is released, at the moment, the pressure in the left cavity of the air cylinder 12 is still greater than that in the right cavity, then the piston rod 13 of the air cylinder 12 automatically stretches forwards, and pushes the grinding wheel frame 5 to move forwards against the resisting surface 15 of the grinding wheel frame 5, so that the grinding wheel 4 is always attached to the surface of the workpiece, in the process, the pressure in the left cavity of the air cylinder 12 is reduced, and then the air stored in the accumulator 23 reenters the air channel and returns to the left cavity of the air cylinder 12, so that the stability of the pressure is ensured; and so on.
Because the accumulator 23 is arranged in the pneumatic system, the pressure change in the air path caused by the reciprocating floating of the piston rod 13 of the air cylinder 12 is compensated or absorbed by the accumulator 23, so that the pressure change is stabilized at preset pressure, the constant thrust of the air cylinder 12 to the grinding wheel frame 5 is ensured, the piston rod 13 of the air cylinder 12 floats along with the floating of the grinding wheel frame 5, the grinding wheel 4 on the grinding wheel frame 5 is ensured to be flexibly attached to the surface of a workpiece all the time, the problem that the surface of the workpiece is burnt due to the fact that the temperature rises too fast caused by overlarge grinding force is avoided, the problem that the convex points on the surface of the workpiece scratch grooves on the surface of the grinding wheel 4 is avoided, and the service life of the grinding wheel 4 is prolonged.
In the case of a small grinding allowance, the sliding platform 6 and the grinding carriage 5 need to be locked for ensuring the machining precision. Therefore, before fine grinding, the air cylinder 12 pushes the grinding carriage 5 to move forwards until the limiting plate 16 at the rear end of the grinding carriage 5 is attached to the rear end face of the sliding platform 6, and then the grinding carriage 5 and the sliding platform 6 are locked into a whole by screwing the two locking screws 18 into threaded holes on the two locking plates 17 respectively and then abutting against the left and right side walls of the sliding platform 6. After the locking, the piston rod 13 of the cylinder 12 is retracted, and the piston rod 13 is separated from the grinding carriage 5, thereby performing fine grinding.
As above, the self-adaptive burn-proof cylindrical grinding machine meets the set processing requirements, the self-adaptive burn-proof cylindrical grinding machine realizes constant pressure grinding through the constant thrust output by the air cylinder 12 by additionally arranging the sliding platform 6 between the cylindrical grinding machine body 1 and the grinding wheel frame 5 and arranging the guide rail and the air cylinder 12 on the sliding platform 6, and on the basis, the purpose of avoiding burn on the surface of a workpiece in the processing process is realized through the way of reducing the grinding force and improving the cooling condition of a grinding processing area. The invention greatly improves grinding conditions, improves the surface quality of the workpiece and prolongs the service life of the grinding wheel 4. The grinding machine is simple in structure, convenient to operate and low in running cost.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
