[0047] When the CBN cutter performs cutting of different intensities on the steel roller 30, the motor 34 is turned on to drive the rotating plate 33 on one side to rotate, and the rotating plate 33 on one side drives the rotating plate 33 on the other side to rotate through the steel roller 30. At this time, the synchronous rod 35 connected to the rotating plate 33 drives the first bevel gear 36 to rotate.

[0049] When fixing the chip breaker grooves of multiple CBN tools before the wear resistance test, the threaded rod 52 is rotated to make the cross plate 53 drive the multiple V-shaped plates 55 close to the inclined surface of the CBN tool, thereby limiting the position of the chip breaker grooves of the CBN tool, thereby effectively preventing the chip breaker grooves of the CBN tool from sliding when being ground. The pressure sensor provided in the V-shaped plate 55 can monitor the grinding force of the chip breaker grooves when the steel roller 30 rotates to perform the wear resistance test on the chip breaker grooves of the CBN tool. At the same time, by rotating the threaded rod 52, the V-shaped plate 55 can be moved close to or away from the CBN tool, so that CBN tools of different specifications and sizes can be fixed before the wear resistance test.

[0050] The adsorption unit 6 includes a side shaft 62, two side shafts 62 are provided, and the side shafts 62 are fixedly connected to the two sides of the special-shaped plate 46 respectively, and folding plates 63 are rotatably installed on the side shafts 62 on both sides. Two symmetrically arranged electric push rods 64 are installed in the middle of the special-shaped plate 46. The telescopic ends of the two electric push rods 64 are hinged with an adsorption box 65, and the circular shafts on both sides of the adsorption box 65 are located in the folding plates 63 on both sides and slide.

[0051] A collecting bucket 651 is detachably installed at the bottom of the adsorption box 65, and an inclined groove 652 is opened on the inclined surface of one side of the adsorption box 65. Rotating shafts 653 that penetrate the adsorption box 65 are rotatably installed on both sides of the adsorption box 65. Fans 654 are fixedly installed on the sides close to the two rotating shafts 653. A pulley 655 is fixedly installed between the side of the rotating shaft 653 away from the fan 654 and the side rod 338 above it, and a belt 656 is commonly connected between the two pulleys 655.

[0052] By setting the pulley 655 and the belt 656, while the steel roller 30 rotates to perform the wear resistance test on the chip breaker groove of the CBN tool, the rotating shaft 653 can synchronously drive the fan 654 to rotate to absorb and collect the waste cut by the steel roller 30 by the CBN tool chip breaker. The electric push rod 64 can be extended and retracted to drive the collection bucket 651 to collect the waste generated when the steel roller 30 is cut in different directions.

[0053] When the steel roller 30 rotates, it is convenient for the CBN tool to perform circumferential cutting and processing on it. When the electric slider drives the two vertical plates 21 to rotate in the same direction, it is convenient to drive multiple CBN tools to rotate synchronously and adjust. ， Then, the direction of the chip breaker groove of the CBN tool is adjusted, thereby regulating the direction of the steel roller 30 during cutting. By cutting the steel roller 30, the wear of the chip breaker groove of the CBN tool during the actual application of the CBN tool is simulated, thereby achieving the wear resistance test of the chip breaker groove of the CBN tool. The steel roller 30 is driven to approach or move away from the CBN tool through the depth adjustment unit 4, so that the chip breaker groove of the CBN tool regulates the cutting depth of the steel roller 30 when the steel roller 30 rotates, so that the wear test of the chip breaker groove of the CBN tool under different intensities can be performed during the wear resistance test.

[0054] When the present invention is in use, multiple CBN tools are placed on the placement cylinder 22 in sequence, and then the placement cylinder 22 is installed between the two vertical plates 21. Then the electric slider is opened to drive the L-shaped plate 26 to move into the card slot 27 to fix the placement cylinder 22. Then the handle is turned, and the handle drives the protrusion 230 to rotate and then squeeze the movable plate 24. Under the squeeze, multiple movable plates 24 are tightly fixed to the inner wall of the circular hole in the middle of the CBN tool, so as to achieve the placement of multiple CBN tool chip breaker grooves before the wear test, and the cross blocks 339 on the two side rods 338 are clamped and fixed to the two sides of the steel roller 30. Then the regulating plate 336 is rotated to make the regulating rod 335 drive the regulating wheel 337 to rotate. The regulating wheel 337 rotates to make the upper dovetail block 332 move downward in the dovetail plate 331. At this time, the triangular groove in the middle of the upper and lower dovetail blocks 332 fixes the side rod 338, so as to drive the steel roller 30 to rotate and perform the wear test on the chip breaker groove of the CBN tool.

[0055] The motor 34 is turned on to drive the rotating plate 33 on one side to rotate, and the rotating plate 33 on one side drives the rotating plate 33 on the other side to rotate through the steel roller 30. At this time, the synchronous rod 35 connected to the rotating plate 33 drives the first bevel gear 36 to rotate. When the first bevel gear 36 rotates, it drives the driving rod 42 to rotate through the second bevel gear 44. The hydraulic rod 490 is turned on and pushed forward to make the fourth bevel gear 491 mesh with the third bevel gear 45. When the driving rod 42 rotates, it drives the fourth bevel gear 491 to rotate through the third bevel gear 45. The rear rod 48 is driven to rotate by the hydraulic rod 490. When the rear rod 48 rotates, the extrusion wheel 49 is driven to rotate so as to extrude the contact wheel 47. When the contact wheel 47 is extruded, the front plates 32 on both sides are driven to move by the special-shaped plate 46. When the two front plates 32 move, the steel roller 30 is driven to approach or move away from the CBN tool, so that the CBN tool cuts the steel roller 30 with different strengths when the steel roller 30 rotates, so as to meet the wear resistance test of the steel roller 30 on the chip breaker groove of the CBN tool with different strengths;

[0056] By rotating the threaded rod 52, the cross plate 53 drives multiple V-shaped plates 55 to approach the inclined surface of the CBN tool, thereby limiting it, thereby effectively preventing the chip breaker groove of the CBN tool from sliding when being ground. The pressure sensor provided in the V-shaped plate 55 can monitor the grinding force of the chip breaker groove when the steel roller 30 rotates to perform a wear test on the chip breaker groove of the CBN tool. At the same time, by rotating the threaded rod 52, the V-shaped plate 55 is moved close to or away from the CBN tool, and CBN tools of different sizes can be fixed before the wear test. The setting of the pulley 655 and the belt 656 can synchronously drive the fan 654 to rotate while the steel roller 30 rotates to perform a wear test on the chip breaker groove of the CBN tool. The shaft 653 can synchronously drive the fan 654 to rotate to absorb and collect the waste cut by the steel roller 30 by the CBN tool chip breaking. The electric push rod 64 is extended and retracted to facilitate the collection bucket 651 to collect the waste generated when the steel roller 30 is cut in different directions.
