Although the device improves detection efficiency to a certain extent, it still has obvious shortcomings. Its fixture structure design is relatively fixed, making it difficult to quickly adapt to ball end mills of different diameters, which is inconvenient and has certain limitations in use.

[0019] 3. Beneficial effects
[0020] Compared with existing technologies, the advantages of this utility model are:
[0021] (1) In this solution, the turntable is driven to rotate by the No. 1 motor. The four clamping plates move radially in sync by the cooperation of the arc groove and the protrusion, so as to quickly clamp and release ball end mills of different diameters. There is no need for frequent manual change of fixtures, which shortens the preparation time before inspection and effectively improves the inspection efficiency. It is especially suitable for batch inspection of multiple types of end mills, which significantly reduces the cost of manual operation and time.
[0022] (2) In this scheme, the No. 2 motor drives the No. 1 gear to mesh with the No. 1 gear ring, so that the mounting frame drives the high-definition camera to rotate circumferentially; at the same time, the reciprocating screw realizes the axial reciprocating motion of the moving block when the mounting frame rotates through the meshing of the No. 2 gear and the No. 2 gear ring. The two motions work together to ensure that the high-definition camera can perform 360-degree scanning and shooting of all parts of the ball end mill without dead angles, capture defects such as minor cracks and wear, avoid blind spots in detection, and improve the accuracy and reliability of detection results.
[0023] (3) In this solution, when the moving block moves under the drive of the reciprocating screw, it simultaneously drives the air cylinder piston to compress the gas, and sprays the airflow through the connecting pipe, telescopic hose and air nozzle to remove the iron filings, cutting fluid and other impurities remaining on the surface of the milling cutter in time, which can effectively avoid the interference of impurities on the high-definition camera's shooting image.

[0036] In some embodiments, please refer to Figure 1-7 An expandable ball end mill testing device includes a mounting base 1, a fixed plate 12 fixedly connected to the top of the mounting base 1, a support frame 13 fixedly connected to the middle of the lower part of the fixed plate 12, a turntable 14 rotatably connected to the lower part of the support frame 13, four arc-shaped grooves 15 are formed on the lower part of the turntable 14, the four arc-shaped grooves 15 are arranged in an equidistant circular array, four sliding plates 16 are slidably connected to one side of the support frame 13, and a protrusion 17 is fixedly connected to one side of each of the four sliding plates 16. The four protrusions 17 are slidably connected to the interior of the four arc-shaped grooves 15, and clamping plates 18 are fixedly connected to the lower part of each of the four sliding plates 16. The four clamping plates 18 are all arc-shaped. A first motor 19 is fixedly connected inside the support frame 13, and the output end of the first motor 19 is fixedly connected to the center of the turntable 14.
[0037] In this embodiment, the turntable 14 is driven to rotate by the No. 1 motor 19. The four arc-shaped grooves 15 below the turntable 14 cooperate with the protrusions 17 on one side of the sliding plate 16 to drive the arc-shaped clamping plates 18 below the four sliding plates 16 to move synchronously radially. This can quickly clamp and fix ball end mills of different diameters. This design eliminates the need for frequent manual changes of fixtures, greatly improves the compatibility of the testing device with different types of end mills, significantly shortens the preparation time before testing, and improves testing efficiency. It is especially suitable for batch testing scenarios of various types of end mills.
[0038] In some embodiments, please refer to Figure 1-7 An expandable ball end mill testing device includes a first gear ring 2 rotatably connected to the lower part of a fixed plate 12. A mounting frame 23 is fixedly connected to the outside of the first gear ring 2. A reciprocating screw 24 is rotatably connected inside the mounting frame 23. A moving block 25 is threadedly connected to the outer wall of the reciprocating screw 24 and slidably connected inside the mounting frame 23. An air cylinder 26 is fixedly connected to one side of the mounting frame 23. The piston end of the air cylinder 26 is fixedly connected to one side of the moving block 25. A connecting pipe 27 is fixedly connected to the output end of the air cylinder 26. A telescopic hose 28 is fixedly connected to one end of the connecting pipe 27, and the end of the telescopic hose 28 is fixedly connected to... There is an air nozzle 29, which is fixedly connected to one side of the moving block 25. A high-definition camera 3 is installed on the other side of the moving block 25. A first gear 21 is rotatably connected to the bottom of the fixed plate 12. The first gear 21 meshes with the first gear ring 2. A second motor 22 is fixedly connected to the top of the fixed plate 12. The output end of the second motor 22 is fixedly connected to the center of the first gear 21. A second gear 31 is fixedly connected to one end of the reciprocating screw 24 near the fixed plate 12. A second gear ring 32 is fixedly connected to the outside of the support frame 13. The second gear 31 meshes with the second gear ring 32. A lighting lamp 11 is installed on the outside of the mounting base 1.
[0039] In this embodiment, motor 22 drives gear 21 to rotate, gear 21 meshes with gear ring 2, and drives mounting frame 23 to rotate circumferentially around the center of fixed disk 12. At the same time, gear 31 at the end of reciprocating screw 24 inside mounting frame 23 meshes with gear ring 32 outside support frame 13. When mounting frame 23 rotates, gear 31 rotates and drives reciprocating screw 24 to rotate, causing moving block 25 to move back and forth along screw axis. High-definition camera 3 is mounted on moving block 25. Through the combination of circumferential rotation and axial reciprocating motion, it can perform 360-degree comprehensive inspection of ball end mills without blind spots. Whether it is the cylindrical surface, spherical surface or cutting edge of the end mill, images can be clearly captured, and defects such as minute cracks and wear can be accurately identified, which greatly improves the comprehensiveness and accuracy of inspection.
[0040] When the moving block 25 reciprocates axially under the drive of the reciprocating screw 24, it synchronously drives the piston of the air cylinder 26 to perform compression and extension actions. When the piston compresses the gas in the air cylinder 26, the gas is ejected from the air nozzle 29 through the connecting pipe 27 and the telescopic hose 28. During the inspection process, it can promptly remove iron filings, cutting fluid and other impurities remaining on the surface of the ball end mill. This not only avoids the interference of impurities on the image captured by the high-definition camera 3 and prevents misjudgment caused by impurities, but also keeps the end mill surface clean, providing good conditions for more accurate subsequent inspection. It realizes the automated collaborative operation of cleaning and inspection, and improves inspection efficiency and reliability.
[0041] Working principle: Start motor 19, its output end drives turntable 14 to rotate. Since there are four arc-shaped grooves 15 arranged in an equidistant circular array below turntable 14, and the protrusion 17 on one side of sliding plate 16 is slidably connected in the arc-shaped grooves 15, as turntable 14 rotates, the protrusion 17 slides along the arc-shaped grooves 15, driving the four sliding plates 16 to move radially synchronously, so that the lower arc-shaped clamping plate 18 opens. After the ball end mill is placed in the middle of the four clamping plates 18, motor 19 is rotated in the opposite direction, the clamping plate 18 retracts and clamps the end mill, completing the loading and fixing.
[0042] When the second motor 22 is turned on, its output drives the first gear 21 to rotate. The first gear 21 meshes with the first gear ring 2, thereby driving the mounting frame 23, which is fixedly connected to the first gear ring 2, to rotate circumferentially around the center of the fixed disk 12. At the same time, the second gear 31 at the end of the reciprocating screw 24 inside the mounting frame 23 meshes with the second gear ring 32 outside the support frame 13. When the mounting frame 23 rotates, the second gear 31 rotates and drives the reciprocating screw 24 to rotate. Since the moving block 25 is threaded to the outer wall of the reciprocating screw 24 and slidably connected inside the mounting frame 23, the rotation of the reciprocating screw 24 causes the moving block 25 to move back and forth along the screw axis.
[0043] The high-definition camera 3, installed on the other side of the moving block 25, performs 360-degree scanning and imaging of various parts of the ball end mill, such as the cylindrical surface, spherical surface, and cutting edge, as the mounting frame 23 rotates circumferentially and the moving block 25 moves axially. Through the image information collected by the high-definition camera 3, the inspection personnel or inspection system can accurately identify defects such as minor cracks and wear on the surface of the end mill.
[0044] As the moving block 25 moves back and forth along the reciprocating screw 24, it simultaneously drives the piston of the air cylinder 26 to perform compression and stretching actions. When the piston compresses the gas in the air cylinder 26, the gas passes through the connecting pipe 27 and the telescopic hose 28 in sequence, and is finally ejected from the air nozzle 29. The air nozzle 29 is fixedly connected to the moving block 25. The ejected airflow can promptly remove residual iron filings, cutting fluid and other impurities on the surface of the ball end mill, avoid impurities from interfering with the image captured by the high-definition camera 3, prevent false judgments caused by reflection or obstruction of impurities, and ensure the smooth progress of the detection process.
[0045] The external lighting 11 of the mounting base 1 is always in working condition, providing sufficient and uniform light to the inspection area. Good lighting conditions can effectively compensate for the impact of problems such as reflection and shadow on the milling cutter surface on the inspection, enabling the high-definition camera 3 to capture the details of the milling cutter surface more clearly, making it easier for inspectors to observe the surface quality of the milling cutter more intuitively and accurately, and improving the ability to identify minor defects.
[0046] After completing the comprehensive inspection of the ball end mill, start motor 19 again to open clamping plate 18, remove the inspected end mill, and then put in the next end mill to be inspected. Repeat the above process to achieve continuous inspection.
[0047] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
