A kind of dresser with measurement mechanism
Technical field
The utility model relates to a kind of repair apparatus that the circular arc molding emery wheel uses that is used to process.
Background technology
The subsidiary at random dresser of existing each grinding machine producer does not generally have measurement mechanism, when the processing circular arc, need the radius of gyration, the forming grinding wheel arc radius that relies on the trial cut method to repair out with the model measurement, try cutter repeatedly in the mode of adjusting gradually, approaching then, not only non-cutting time long, when allowance is little, also be easy to generate product rejection, service life of dresser is short.In addition, the rotary support of dresser and base all adopt plane contact, have the defective of quick abrasion.
The utility model content
The technical problems to be solved in the utility model provides a kind of dresser with measurement mechanism, can not only regulate the arc radius that adjusts required finishing intuitively, can also repair arc radius in a big way, and is also wear-resistant simultaneously.
For solving the problems of the technologies described above, the dresser that the utility model proposes mainly is made up of base, rotary support, pole and diamond pen, described rotary support is installed on the base, be connected contact with thrust bearing by ball bearing between them, pivot at rotary support is manufactured with a datum hole, and with the supporting standard correction rod that is provided with of datum hole.Described diamond pen is clamped in pole one end by the holding screw location, is carved with scale on the pole, and described pole is passed through the holding screw clamping on rotary support.
Described ball bearing is a deep groove ball bearing, and described thrust bearing is a single thrust bearing.
Adopt the dresser of above structure, have scale because the pole of diamond pen is installed, can identify the arc radius of diamond pen vertex distance pivot intuitively, accomplish accurate finishing according to the size of required finishing radius, reduce non-cutting time, improved crudy and efficient.When the arc radius at the different size scope required, the pole of replaceable different size was to adapt to requirement.Because the rotating mechanism that rotary support and base are formed adopts ball bearing and thrust bearing, make this rotating mechanism can bear the axial and radial load that trimming wheel brings, reduce the plane and rotated wearing and tearing, improve rotation precision, prolong the service life of emery wheel repairing device.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Dresser shown in Figure 1 mainly is made up of base 1, rotary support 7, pole 6 and diamond pen 5, rotary support 7 be installed on the base 1, realize being connected contact by deep groove ball bearing 2 and single thrust bearing 3, be manufactured with a datum hole 10 at the pivot of rotary support 1.Diamond pen 5 is clamped in pole 6 one ends by holding screw 8 location, and pole 6 is passed through holding screw 9 clampings on rotary support 7.Wherein on the pole 6 scale is arranged, when work, can select the pole of different size specification as required.What this dresser adopted is knockdown rotational structure, and rotary support 7 rotates on base 1 by deep groove ball bearing 2 and single thrust bearing 3, and pivot is set by standard correction rod 4.
After changing diamond pen,, therefore need to adopt the standard correction rod to measure datum readings because its length of diamond pen of manual riveted is a unknown number.The standard correction rod is inserted in the datum hole of pivot, Buddha's warrior attendant nib applying standard correction rod is read scale value, draws a datum readings A, this datum readings is the datum readings that adopts this diamond pen, does not change that this value is a steady state value under the situation of diamond pen.
Fig. 2 has provided the operation chart of this dresser.When carrying out the crushing of requirement radius R, take down the standard correction rod, adjust pole, make final scale reading B=A+R, fastening holding screw 9, the rotary support of holding with a firm grip by hand rotates on bearing, the Buddha's warrior attendant nib is contacted with the emery wheel that needs finishing, can repair out required arc radius R, referring to Fig. 3.
