Detailed Description

The invention will be further described with reference to examples of embodiments shown in the drawings.

The special grinding wheel dressing jig shown in fig. 1 and 2 mainly comprises a support assembly 1, a power assembly 2, a track assembly 3, a dressing tool bit 5 and the like.

The support assembly 1 includes a base plate 11, a slide rail 12 mounted on the upper surface of the base plate 11 (the mounting manner may be conventional bolt, screw, etc. for fixing), a support base 13 slidably mounted on the slide rail 12 through a slider 10 (i.e. the slider 10 is slidably mounted on the slide rail 12; the support base 13 is formed by splicing a flat plate and a vertical plate, the flat plate is mounted on the slider 10 through a connector such as a bolt, etc.), a carrier plate 14 bidirectionally slidably mounted on the support base 13 (i.e. on the flat plate of the support base 13) through an elastic mechanism 16, and a limit protrusion 15 fixed on the bottom surface of the carrier plate 14, wherein the sliding direction of the carrier plate 14 is perpendicular to. The track assembly 3 includes a fixed base plate 31 mounted on the upper surface of the base plate 11 and parallel to the slide rail 12, and a position-limiting plate 32 mounted above the fixed base plate 31 by a plurality of fasteners 33 (bolts, etc.), wherein the position-limiting plate 32 is formed with a forming groove/protrusion 321 (i.e. a forming portion, which may be a forming groove or a forming protrusion) facing the edge of the slide rail 12, the forming groove/protrusion 321 corresponding to the shape of the outer contour to be machined by the grinding wheel. The dressing tool bit 5 is fixed on the carrier plate 14 through the mounting seat 6, and the grinding wheel is dressed correspondingly by the dressing tool bit 5. The power assembly 2 comprises supporting blocks 21 fixed on two sides of the base plate 11, a base 22 installed on the base plate 11 and corresponding to the supporting blocks 21, a screw 23 rotatably inserted in the supporting blocks 21, a threaded sleeve 24 with an end connected with the supporting base 13 and installed on the screw 23, and a bidirectional motor 25 connected with an end of the screw 23 and installed on the base 22.

The working principle of the special grinding wheel dressing jig is as follows: the bidirectional motor 25 drives the screw 23 to rotate (can rotate forward or backward), correspondingly drives the threaded sleeve 24 to move on the screw 23, further synchronously drives the supporting seat 13 to move on the sliding rail 12, and enables the limiting protrusion 15 to cling to the limiting plate 32 (namely, to contact with the limiting plate 32 towards the edge of the sliding rail 12) through the elastic mechanism 16, so that the edge is used as a track to move, and the trimming tool bit 5 is used for processing the peripheral surface of the grinding wheel to form a required outer contour (usually, the limiting plate 32 with a corresponding structure is designed according to the outer contour of the grinding wheel).

In this embodiment, the special grinding wheel dressing jig further includes a control switch 4 mounted on the upper surface of the substrate 11 and connected to the bidirectional motor 25, and the control switch 4 is connected to the bidirectional motor 25 by using a conventional control circuit for controlling the rotation direction and the rotation speed of the bidirectional motor 25. The carrier plate 14 is mounted on the supporting seat 13 in a bidirectional slidable manner through an elastic mechanism 16, and specifically, the elastic mechanism 16 includes a plurality of guide rods with one ends fixed on the supporting seat 13 (usually on a vertical plate of the supporting seat 13) and parallel to the carrier plate 14, a moving block fixed on a bottom surface of the carrier plate 14 and supported on the supporting seat 13 (the moving block is sleeved on the guide rods and limited by free ends of the guide rods, for example, the other ends of the guide rods are engaged with the moving block), and a spring sleeved on the guide rods and located between the moving block and the supporting seat 13.

As described above, the present invention has been explained in full in accordance with the spirit of the present invention, but the present invention is not limited to the above-described embodiments and implementation methods. The practitioner of the related art can make various changes and implementations within the scope permitted by the technical idea of the present invention.
