Definitions

  • the present invention is relates to a vibration stop device necessary for stopping vibration of a work in a process stage.
  • the work is divided into a processing region and a non-processing region along a circumferential direction, and in many cases, moves together with a main shaft in a state where a holding part for vibration stop is in pressure contact with an already processed region of the work.
  • the pressure contact state causes a problem that the pressure contact region of the holding part intrudes into a region recessed by the processing, in the other words, in a recess, and even if the work is to be rotated along a columnar center axis for the next processing, such rotation is hindered due to the intrusion.
  • Patent Document 1 describes, regarding a camshaft work to be ground, a processing region and vibration stop for the work, nevertheless has no particular description on the relationship between the processing region and the vibration stop.
  • Patent Document 2 describes both processing on a work and a vibration stop device, but does not describe the problem arising when the pressure contact region comes into contact with the region that has already been processed.
  • Patent Document 1 JP 2005-169530 A
  • Patent Document 2 JP 2010-99746 A
  • An object of the present invention is to provide a configuration of a vibration stop device that can prevent a problem caused by a pressure contact region of a holding part of the vibration stop device intruding into a recess of a region that has been processed.
  • the present invention has the following basic structure:
  • the pressure contact region of the holding part of the vibration stop device never introduces into the recess in the processing region, and so, the problem in the rotation of the work due to the intrusion can be prevented.
  • the position of the holding parts can be independently adjusted, whereby the precision error of the work can be easily corrected.
  • FIG. 1 is a side cross-sectional view of a first embodiment.
  • FIG. 2 is a side cross-sectional view of a second embodiment.
  • FIG. 3 is a side cross-sectional view of a third embodiment.
  • FIG. 4 is a side cross-sectional view of a vibration stop device of an example 1, and also includes a block diagram showing a configuration of an oil pressure supplying device of an example 2.
  • FIG. 5 is a side cross-sectional view of a configuration of a vibration stop device of the prior art.
  • the present invention has a feature that, regarding the angular range based on a position of an axis of rotation of a columnar work 2 , an angular range formed by both ends of each of a holding part for vibration stop 11 is larger than an angular range of a processing region 21 .
  • FIGS. 1 to 3 show typical embodiments.
  • FIG. 1 shows the first embodiment having a feature that a holding part has an arc shaped surface on the pressure contact side, and a radius of curvature of the arc is the same as the radius of the work 2 .
  • pressure contact can be done mainly at a non-processing region 22 .
  • FIG. 2 shows the second embodiment having a feature that the holding part for vibration stop 11 has an arc shaped surface on the pressure contact side, and a radius of curvature of the arc is larger than the radius of the work 2 .
  • FIG. 3 shows the third embodiment having a feature that the holding part for vibration stop 11 has a flat surface on the pressure contact side.
  • the surface of the holding part for vibration stop 11 on the pressure contact side might come into contact with or come close to a surface of the processing region 21 , as shown in FIGS. 2 and 3 .
  • the holding part for vibration stop 11 never intrudes into the recess of the processing region 21 as in the first embodiment. This is because the angular range formed by both ends of each of the holding part for vibration stop 11 is formed to be larger than an angular range of the processing region 21 .
  • a pair of the holding parts for vibration stop 11 comes into pressure contact with both sides of the work 2 , and the two sides of the work 2 are rotatably connected to the pair of the holding parts for vibration stop 11 , and a pressure transmission part 12 which is interlocked with a single hydraulic cylinder 31 is provided, such that approaching and separating of the holding parts for vibration stop 11 to and from the work 2 are achieved by changing oil pressure.
  • the holding parts for vibration stop 11 are in pressure contact with both sides of the non-processing regions 22 and at least four pressure contact regions are formed.
  • the holding part for vibration stop 11 for directly transmitting the oil pressure from the hydraulic cylinder 31 is not required to be provided in addition to the holding parts for vibration stop 11 for sandwiching the work 2 from both sides.
  • the holding parts for vibration stop 11 are not necessarily in pressure contact with both sides of the non-processing regions 22 .
  • the pressure contact is made on two positions of the processing regions 21 , and so the pressure contact state is achieved at substantially two points.
  • the third holding part for vibration stop 11 that directly presses and comes into pressure contact with the work 2 by the pressure from the hydraulic cylinder 31 may be provided.
  • the first embodiment does not require the third holding part for vibration stop 11 , and thus can achieve a simpler design and lower cost compared with the second and third embodiment.
  • the first embodiment requires the holding parts for vibration stop 11 having radii of curvature respectively corresponding to the various radii of the works 2 , and thus is more cumbersome than the second and third embodiment in this point.
  • the example 1 has a feature that the holding parts for vibration stop 11 are each independently interlocked with a hydraulic cylinder 31 , and approaching and separating of the holding parts for vibration stop 11 to and from the work 2 are achieved by changing the oil pressure.
  • the conventional technique shown in FIG. 5 and the embodiments shown in FIGS. 1 to 3 require cumbersome control such as an operation of the pressure transmission part 12 , and movement of the third holding part for vibration stop 11 .
  • the rotation state can be achieved by immediately releasing, from each of the holding parts for vibration stop 11 , pressure supplied from the hydraulic cylinder 31 , and the precision error can be quickly corrected.
  • a number of the holding parts for vibration stop 11 and a number of the hydraulic cylinders 31 shown in the example 1 are each three.
  • the example 2 has a feature that a relief valve 34 is provided in juxtaposition with the solenoid valve 33 which supplies the oil pressure to the vibration stop device, in a hydraulic circuit that creates the pressure contact state.
  • a hydraulic cylinder 31 a pressure reducing valve 32 for adjusting the pressure, and the solenoid valve 33 for turning ON and OFF transmission of reduced pressure are used as in the conventional technique, and the relief valve 34 in parallel with an oil pressure circuit is further provided.
  • the present invention can achieve the vibration stop without the problem of intrusion into the recess of the processing region, and can quickly correct the precision error, and thus is extremely useful.
