At the same time, the present invention can also clean the chips in the groove opened by the milling cutter on the test piece, and detect the flatness of the bottom wall of the groove, thereby increasing the performance detection efficiency of the milling cutter.

[0036] The active device 3 is used to drive the milling cutter to groove the test piece; specifically, first, the milling cutter is clamped by the main shaft part 33, and the corresponding correction plate 23 is selected and installed on the upper end of the clamping plate 21, and then the test piece is placed between the two clamping plates 21, and the synchronous part 22 is controlled to drive the two clamping plates 21 to move in a direction close to each other, so that the two clamping plates 21 clamp and fix the test piece, and then the multi-stage push rod 32 is controlled to drive the main shaft part 33 to move to the left through the integrated plate 31, and the main shaft part 33 is controlled to drive the milling cutter to rotate, so that the milling cutter can groove the test piece, and the flatness of the bottom wall of the groove of the test piece is detected by the detection device 5 to see if it is qualified. After the detection device 5 completes the flatness detection of the bottom wall of the groove of the test piece, the synchronous part 22 is controlled to drive the two clamping plates 21 to move away from each other, and then the test piece is taken out. If the flatness of the bottom wall of the groove is qualified, the flatness and verticality of the front and rear inner walls of the groove of the test piece are manually tested to test whether the performance of the milling cutter is qualified.

[0037] See also Figure 1 , Figure 3 and Figure 4 The cleaning device 4 includes a square block 41 distributed on the right side of the lower end of the integrated board 31, an adjusting component 42 for adjusting the height of the square block 41 is connected between the upper end of the square block 41 and the integrated board 31, a connecting rod 44 is installed on the lower end of the square block 41 for sliding up and down through a reset spring 43, a connecting block 45 is fixedly installed on the lower end of the connecting rod 44, a cleaning rod 46 with an elastic telescopic structure is fixedly installed on the left end of the connecting block 45, a scraping unit 48 for scraping off chips is installed on the right end of the square block 41, and a matching unit 47 for compressing the telescopic end of the cleaning rod 46 is connected between the scraping unit 48 and the telescopic end of the cleaning rod 46.

[0038] It should be noted that the adjustment component 42 in the present invention includes an adjustment screw, which is connected to the upper end of the front side of the square block 41 by threaded cooperation, and the upper end of the adjustment screw is rotatably connected to the integrated board 31. The adjustment component 42 also includes a guide rod, which is slidably installed on the front and rear sides of the upper end of the square block 41, and the upper end of the guide rod is fixedly connected to the integrated board 31. When the height of the square block 41 needs to be adjusted, the adjustment screw is screwed to make the square block 41 move up and down under the action of the guide rod.

[0039] The cleaning device 4 is used to clean the chips remaining on the milling cutter; specifically, firstly, the adjusting component 42 is controlled to adjust the height of the square block 41, so that the square block 41 drives the cleaning rod 46 to move through the connecting rod 44 and the connecting block 45, so that the cleaning rod 46 moves to the corresponding position of the milling cutter cutting groove. When the spindle member 33 clamps and fixes the milling cutter, the telescopic end of the cleaning rod 46 can be compressed by the milling cutter, so that the left end of the cleaning rod 46 can fit on the milling cutter. When the milling cutter rotates, the cutting groove of the milling cutter can drive the cleaning rod 46 to move downward, so that the cleaning rod 46 can clean the chips in the cutting groove of the milling cutter. At the same time, the cleaning rod 46 drives the connecting rod 44 and the connecting block 45 to move downward. The rod 44 moves downward and compresses the reset spring 43. When the cleaning rod 46 moves to the lower limit position, the cleaning rod 46 is compressed and moved out of the cutting groove under the action of the matching unit 47. At the same time, the cleaning rod 46 returns to the initial position under the action of the reset spring 43, and the telescopic end of the cleaning rod 46 can be attached to the milling cutter again, so that the cleaning rod 46 can repeat the above steps, and then the cleaning rod 46 continues to clean the cutting groove of the milling cutter, and when the integrated board 31 moves to the left, the integrated board 31 drives the square block 41 to move to the left through the adjustment component 42, so that the square block 41 drives the scraping unit 48 to clean the debris in the groove where the milling cutter is opened on the test piece.

[0040] See also Figure 4 and Figure 6 The scraping unit 48 includes an electric slider assembly 481 installed on the upper right side of the square block 41, a vertical plate 482 is installed on the right side of the electric slider assembly 481, and scraping plates 483 are installed on the lower sides of the front and rear ends of the vertical plate 482 for sliding forward and backward. A fitting unit 484 is connected between the two scraping plates 483 and the vertical plate 482 to make the two scraping plates 483 fit against the inner wall of the groove.

[0041] The scraping unit 48 is used to scrape the debris in the groove opened by the milling cutter in the test piece to the left; specifically, first control the No. 1 electric slider assembly 481 to drive the vertical plate 482 to move downward, so that the lower end of the vertical plate 482 is aligned with the bottom wall of the groove opened by the milling cutter in the test piece. At this time, the vertical plate 482 is located at the corresponding position on the right end of the test piece. When the integrated board 31 finally drives the square block 41 to move to the left through the adjustment assembly 42, the square block 41 drives the vertical plate 482 to move to the left through the No. 1 electric slider assembly 481, and the lower end of the vertical plate 482 can move along the bottom wall of the groove opened by the milling cutter in the test piece, so that the vertical plate 482 can scrape the chips on the bottom wall of the groove to the left, and at the same time, the two scraping plates 483 are attached to the front and rear side walls of the groove under the action of the bonding unit 484, so that the scraping plates 483 scrape the chips on the front and rear side walls of the groove.

[0042] See also Figure 3-Figure 5The matching unit 47 includes a synchronous rod 471 fixedly mounted on the upper end of the telescopic end of the cleaning rod 46, and a U-shaped rod 472 is fixedly mounted on both the front and rear sides of the upper end of the synchronous rod 471. The matching unit 47 also includes a matching plate 473 fixedly mounted on the upper right end of the vertical plate 482. The front and rear sections of the matching plate 473 are both provided with a return groove 474. The lower end of the return groove 474 is set to an inclined structure with a left high and a right low, and the left vertical section of the return groove 474 has a width in the left and right directions greater than the width in the left and right directions of the right vertical section. In terms of the upward width, the right end of the U-shaped rod 472 is arranged in the circular groove 474, wherein the U-shaped rod 472 is arranged to be cylindrical, and the width of the upper horizontal section of the circular groove 474 in the vertical direction is much larger than the diameter of the U-shaped rod 472; the lower end of the right side of the inclined section of the circular groove 474 is slidably installed with a limit block 476 through a connecting spring 475, and the left side of the upper end of the limit block 476 is arranged to be an inclined surface, and the limit block 476 enables the U-shaped rod 472 to move only from left to right along the inclined section of the circular groove 474.

[0043] The mating unit 47 is used to compress the telescopic end of the cleaning rod 46; specifically, when the telescopic end of the cleaning rod 46 is attached to the milling cutter, since the width of the vertical section on the left side of the circular groove 474 is greater than the vertical section on the right side, the telescopic end of the cleaning rod 46 can be attached to milling cutters of different sizes. When the No. 1 electric slider assembly 481 is controlled to drive the vertical plate 482 to move downward, the vertical plate 482 can drive the mating plate 473 to move downward synchronously. Since the milling cutter is rotating, the cleaning rod 46 can move into the cutting groove of the milling cutter and move from top to bottom along the cutting groove to clean the cutting groove. When the cleaning rod 46 moves When it moves to the lower end of the milling cutter cutting groove, the cleaning rod 46 drives the right end of the U-shaped rod 472 to move to the corresponding position of the inclined structure at the lower end of the circular groove 474 through the synchronous rod 471. At this time, the right end of the U-shaped rod 472 drives the telescopic end of the cleaning rod 46 to move to the right through the synchronous rod 471 under the action of the inclined structure of the circular groove 474, and the right end of the U-shaped rod 472 can cooperate with the inclined surface of the limit block 476 to drive the limit block 476 to move downward so that the U-shaped rod 472 can move to the right side of the vertical section of the circular groove 474, and then the U-shaped rod 472 compresses the telescopic end of the cleaning rod 46 through the synchronous rod 471 and moves out of the cutting groove.

[0044] When the right end of the U-shaped rod 472 moves to the right vertical section of the return groove 474, the limit block 476 returns to the initial position under the action of the connecting spring 475, and the limit block 476 enables the right end of the U-shaped rod 472 to move only along the right vertical section of the return groove 474, and the cleaning rod 46 drives the U-shaped rod 472 to move along the right vertical section of the return groove 474 to the upper horizontal section of the return groove 474 through the synchronous rod 471 under the action of the return spring 43, and the cleaning rod 46 can drive the U-shaped rod 472 to move along the upper horizontal section of the return groove 474 to the left vertical section of the return groove 474 through the synchronous rod 471 under its elastic action, so that the telescopic end of the cleaning rod 46 can be attached to the milling cutter again, so that the cleaning rod 46 can continue to clean the chips on the milling cutter, and the vertical plate 482 can drive the matching plate 473 to move downward synchronously, so that the cleaning rod 46 can continue to clean milling cutters of different sizes, thereby increasing the applicability of the present invention.

[0049] The detection device 5 is used to detect the flatness of the bottom wall of the groove opened by the milling cutter in the test piece; specifically, when the vertical plate 482 moves to the left, the No. 2 electric slider assembly 51 is controlled to drive the transmission block 52 to move back and forth left and right according to the width of the groove. When the transmission block 52 drives the detection rod 54 to move to the corresponding position of the right side correction plate 23, the control limit unit 56 releases the lock of the detection rod 54, so that the detection rod 54 is attached to the upper side of the correction plate 23 under the action of the clamping spring 53. When the transmission block 52 moves to the left in the groove, the detection rod 54 moves to the left along the bottom wall of the groove. When there are protrusions and depressions on the bottom wall of the groove, the detection rod 54 can move up and down, so that the detection rod 54 triggers the alarm unit 55. If the alarm unit 55 alarms, the performance of the milling cutter is unqualified. Otherwise, the flatness and verticality of the front and rear side walls of the test piece groove are tested to determine whether the performance of the milling cutter is qualified.
