Example 1:
referring to fig. 1 to 5, the present embodiment provides a CBN blade with a positioning groove, which is used in cooperation with a tool holder.
The blade 100 is a diamond-shaped blade 100, and a positioning groove 110 is formed at the center of one surface of the blade 100. The bottom of the positioning groove 110 is provided with screw through holes 130 penetrating through opposite surfaces of the blade 100.
The tool holder includes a holder body 220, a clip 210, and a screw. The base 220 is provided with an expansion block receiving groove 222 and a plurality of positioning protrusions 221. The slot of the expansion block receiving slot 222 is opened on the upper surface of the seat body 220. The positioning protrusions 221 are disposed on the base 220 and distributed around the notches of the expansion block receiving groove 222. The positioning protrusions 221 are disposed in cooperation with the positioning groove 110, so that when the blade 100 is placed on the base 220, the positioning protrusions 221 are received in the positioning groove 110, and the positioning groove 110 just receives the positioning protrusions 221.
The expansion block accommodating groove 222 is a regular hexagonal groove, and a regular hexagonal expansion block 223 is provided therein. The expansion block 223 is slightly smaller than the expansion block receiving groove 222, so that the expansion block 223 can be placed in the expansion block receiving groove 222 and slide along the expansion block receiving groove 222, but the expansion block 223 cannot rotate in the expansion block receiving groove 222. The expansion block 223 is provided with a threaded hole 2230. The positioning protrusions 221 are obliquely disposed near one side of the expansion block receiving groove 222, so that gaps between the positioning protrusions 221 are gradually reduced and smaller than the inner diameter of the expansion block receiving groove 222. When the expansion block 223 moves out of the expansion block receiving groove 222 and passes through the positioning protrusions 221, the expansion block 223 can squeeze the positioning protrusions 221 to make the positioning protrusions 221 away from each other.
The base 220 is further provided with a plug slot 224, and the clip 210 is provided with a plug block 211 that can be plugged into the plug slot 224, so that the clip 210 can be fixed on the base 220 through the plug block 211. The clip 210 is provided with a coupling hole 213, and the coupling hole 213 of the clip 210 communicates with the screw through hole 130 and the screw hole of the expansion block 223 when the clip 210 is fixed to the housing 220. The screw is inserted into the connection hole 213 and the screw through hole 130 and is engaged with the expansion block 223, so that the clip 210, the blade 100 and the holder body 220 are fixedly connected.
When the CBN blade with positioning groove of the present invention is used, the blade 100 is placed on the seat body 220 and the positioning protrusions 221 are accommodated in the positioning groove 110. At this time, the screw through hole 130 of the insert 100 and the screw hole of the expansion block 223 are communicated and concentric. Subsequently, the clip 210 is placed over the insert 100 such that the insertion block 211 is inserted into the insertion groove 224 and the connection hole 213 communicates with the screw hole. Finally, the screw is inserted into the coupling hole 213 and the screw through hole 130 and fitted to the expansion block 223. When the screw is rotated, the expansion block 223 moves from the inside of the expansion block receiving groove 222 to the outside thereof by the screw. When the expansion block 223 abuts against the plurality of positioning protrusions 221 and continues to move out of the expansion block receiving groove 222, the expansion block 223 presses the plurality of positioning protrusions 221. The plurality of positioning protrusions 221 are expanded away from each other by the expansion block 223. The plurality of positioning protrusions 221 expand such that the positioning protrusions 221 expand within the positioning slot 110, thereby securing the blade 100 to the plurality of positioning protrusions 221.
After the blade 100 is fastened on the positioning protrusions 221, no gap exists between the groove wall of the positioning groove 110 and the positioning protrusions 221, and the sliding and the movement of the blade 100 in the use process are effectively avoided. Ensuring stability of the blade 100 during use.
Further, a limiting groove 120 is formed on one side of the blade 100 close to the clip 210. The clip 210 is provided with a plurality of limiting protrusions 212 in cooperation with the limiting grooves 120. A plurality of limiting protrusions 212 are disposed on the clip 210 and distributed around the opening of the connection hole 213. The plurality of limiting protrusions 212 are disposed in cooperation with the limiting grooves 120, so that when the clamping piece 210 is placed on the blade 100, the limiting protrusions 212 are received in the limiting grooves 120, and the limiting grooves 120 just receive the limiting protrusions 212.
The limiting protrusions 212 are obliquely arranged at one side close to the opening of the connecting hole 213, so that gaps among the limiting protrusions 212 are gradually reduced and smaller than the inner diameter of the connecting hole 213. During the tightening process of the screw, the nut may compress the plurality of retaining protrusions 212 such that the plurality of retaining protrusions 212 move away from each other.
This arrangement allows one side of the blade 100 to secure the blade 100 to the clip 210 by the engagement of the retention slot 120 and the retention projection 212; the other side of the blade 100 fastens the blade 100 and the holder body 220 through the cooperation of the positioning groove 110 and the positioning protrusion 221. This allows both sides of the blade 100 to be fixed, and the blade 100 to be more securely fixed, preventing the blade 100 from moving during use.
Further, the positioning groove 110 and the limiting groove 120 are square. The number of the limit protrusions 212 is 4. The 4 limit protrusions 212 are arranged in a square shape. The number of the positioning projections 221 is 4. The 4 positioning projections 221 are arranged in a square. This prevents the blade 100 from rotating after the blade 100 is fixed, thereby ensuring the stability of the connection of the blade 100.
Further, the position-limiting protrusion 212 and the positioning protrusion 221 are both made of spring steel. The spring steel has better elasticity, and can better meet the elasticity requirements of the limiting bulge 212 and the positioning bulge 221.
Further, the insertion groove 224 is a rectangular groove, and the insertion block 211 is quadrangular. When the insertion block 211 is inserted into the insertion groove 224, the clip 210 cannot rotate, thereby further preventing the blade 100 from rotating.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
