[0031] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0032] Example:

[0033] See also Figure 1 and Figure 2 An online detection device for wear of a ball-end milling cutter comprises a base 1, a support base 2, a three-jaw chuck 3, a motor 4, a support rod 5, a background plate 6 and a camera 7. Specifically, a support base 2 is fixedly arranged at one end of the top surface of the base 1, the support base 2 is vertically arranged on the base 1, and a three-jaw chuck 3 is rotatably arranged at the top of the support base 2, and the rotation axis of the three-jaw chuck 3 at the top of the support base 2 is arranged in the horizontal direction.

[0034] The motor 4 is arranged on the base 1, and the output shaft of the motor 4 is connected to the three-jaw chuck 3. Generally, the motor 4 and the three-jaw chuck 3 are connected to each other by a pulley structure or a gear mechanism. The motor 4 can directly drive the three-jaw chuck 3 to rotate continuously at the top of the support seat 2.

[0035] The background plate 6 is detachably connected to the support base 2 through the support rod 5. At the same time, there is a hole on the background plate 6. In addition, there is a gap between the background plate 6 and the three-jaw chuck 3, and the background plate 6 is located on the side of the three-jaw chuck 3 away from the support base 2. At the same time, a pure color paint is evenly applied on the side of the background plate 6 away from the three-jaw chuck 3, generally using a high-brightness color such as green or pure blue.

[0036] The camera 7 is mounted on the base 1 , and one end of the camera 7 has a lens facing the clamping area of ​​the three-jaw chuck 3 . There is also a distance between the camera 7 and the background plate 6 , so that the background plate 6 is located between the three-jaw chuck 3 and the camera 7 .

[0037] In this technical solution, the camera 7 is connected to a computer via a data cable, and the computer is equipped with built-in graphics comparison software.

[0038] The working principle of this embodiment is to clamp the worn ball end milling cutter on the three-jaw chuck 3, then pass the ball end milling cutter through the hole on the background plate 6, and install the background plate 6 on the end of the support rod 5. In addition, since the background plate 6 is a detachable structure, background plates 6 with different hole diameters can be selected according to ball end milling cutters of different sizes.

[0039] The camera 7 takes a picture of the worn ball end milling cutter, and then uploads the picture data to a computer. The worn ball end milling cutter is compared with a standard ball end milling cutter by software in the computer to obtain the degree of wear.

[0040] In addition, during the shooting process, the camera 7 drives the three-jaw chuck 3 to rotate through the motor 4, so as to take pictures of the ball end milling cutter at different angles, and compare them from multiple angles to obtain accurate wear values.

[0041] This technical solution has the advantages of rapid comparison and high comparison accuracy.

[0042] In one specific embodiment:

[0043] A magnet is arranged on one end of the support rod 5 away from the support base 2, and an iron sheet attracted to the magnet is arranged on the background plate 6. The magnet and the iron sheet attract each other, so that the difficulty of installing and removing the background plate 6 can be reduced.

[0044] In another specific embodiment:

[0045] The ball end milling cutter wear online detection device further comprises an arc track 8. Specifically, one end of the arc track 8 is mounted on the base 1, the arc track 8 and the support base 2 are respectively located at two ends of the base 1, and the concave side of the arc track 8 faces the background plate 6.

[0046] The camera 7 is slidably mounted on the arc track 8, so that the camera 7 can slide on the arc track 8. Generally, a chain is arranged in the arc track 8, and the rotation of the chain is driven by a driving mechanism such as a motor, thereby driving the movement of the camera 7 through the chain.

[0047] When the camera 7 rotates on the slideway, the axis of the camera 7 rotation is located between the background plate 6 and the arc track 8. After the ball end milling cutter is installed on the three-claw chuck, the camera 7 rotates around the end of the ball end milling cutter.

[0048] In this embodiment, the background plate 6 is L-shaped, and the central angle of the arc track 8 is greater than or equal to 90°. Specifically, one end of the arc track 8 is fixedly arranged on the base 1, and the other end is located right in front of the three-jaw chuck 3. When the camera 7 is located at the bottom end of the arc track 8, one end of the lens of the camera 7 is just vertically facing upwards. When the camera 7 is located at the bottom end of the arc track 8, one end of the lens of the camera 7 is just facing the three-jaw chuck 3.

[0049] In addition, one end of the L-shaped background plate 6 is located right in front of the three-jaw chuck 3, and the other end is located above the ball-end milling cutter after installation.

[0050] Through the technical solution, the camera 7 slides on the arc track 8, thereby cooperating with the rotation of the motor 4 to shoot pictures of the ball-end milling cutter at different angles, so as to make a comprehensive comparison in the computer software, thereby achieving the purpose of accurately judging the degree of wear. In addition, the background plate 6 is set to be L-shaped, so that when the camera 7 takes pictures at different angles, the ball-end milling cutter has a solid color background, which is convenient for the computer to recognize the shape of the ball-end milling cutter.

[0051] In another specific embodiment:

[0052] LED lights are arranged around the lens of the camera 7, and the brightness of the ball head milling cutter is increased by the LED lights, thereby improving the recognition rate of the picture.

[0053] In another specific embodiment:

[0054] The corners of the background plate 6 are in an arc-shaped structure, so when taking pictures at different angles, the background plate 6 will not produce any lines other than the frame on the picture.

[0055] In another specific embodiment:

[0056] The center of the camera 7 when rotating is located on the axis of the three-jaw chuck 3, thereby ensuring that the center of the picture taken by the camera 7 is located on the center of the ball-end milling cutter, which is convenient for the computer to position the picture.

[0057] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
