[0036] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0037] Please refer to Figure 1 The milling cutter appearance inspection device 100 provided in the embodiments of the present invention can solve the above problems, and will be described in detail below.

[0038] The milling cutter appearance inspection device 100 includes a conveying mechanism 110, a height adjustment mechanism 120, a first acquisition mechanism 130, a second acquisition mechanism 140, and a rotary clamping mechanism 150;

[0039] The conveying mechanism 110 is used to convey the milling cutter. The height adjustment mechanism 120, the first acquisition mechanism 130 and the second acquisition mechanism 140 are arranged sequentially along the conveying direction. The rotating clamping mechanism 150 is arranged corresponding to the second acquisition mechanism 140. The rotating clamping mechanism 150 is used to clamp and drive the milling cutter to rotate. The first acquisition mechanism 130 is used to perform appearance inspection on the end face of the milling cutter. The second acquisition mechanism 140 is used to perform appearance inspection on the peripheral wall of the milling cutter.

[0040] During operation, the milling cutter appearance inspection device 100 can transport the milling cutter by the conveying mechanism 110, and the height adjustment mechanism 120 is used to adjust the milling cutter to the inspection height. The first acquisition mechanism 130 performs end face appearance inspection on the milling cutter, and the second acquisition mechanism 140 cooperates with the rotating clamping mechanism 150 to perform peripheral wall inspection on the milling cutter. It can integrate the end face and peripheral wall inspection of the milling cutter, thereby simplifying the inspection steps and improving the inspection efficiency.

[0041] In addition, the milling cutter appearance inspection device 100 also includes a main frame 160, a conveying mechanism 110, a height adjustment mechanism 120, a first acquisition mechanism 130, a second acquisition mechanism 140, and a rotating clamping mechanism 150, all of which can be connected to the main frame 160, thereby ensuring the relative position stability of each mechanism.

[0042] Please refer to Figure 1 and Figure 2 The conveying mechanism 110 includes a rotary disk 111 and a plurality of clamping seats 112. The plurality of clamping seats 112 are evenly arranged along the circumference of the rotary disk 111. The front end of the clamping seat 112 protrudes from the edge of the rotary disk 111 and is used to clamp the milling cutter.

[0043] To further improve inspection efficiency and achieve streamlined inspection of milling cutters, the height adjustment mechanism 120, the first acquisition mechanism 130, and the second acquisition mechanism 140 can be positioned to correspond to different clamping seats 112 at different workstations, thereby allowing the milling cutters to undergo height adjustment, end face inspection, and peripheral wall inspection in an orderly manner. The protruding rotating disk 111 at the front end of the clamping seat 112 facilitates the clamping of longer milling cutters, preventing the bottom end of the cutter from being interfered with by the rotating disk 111.

[0044] In this embodiment, there are six clamping seats 112, and the rotating disk 111 rotates simultaneously, causing the six clamping seats 112 to rotate as well. Of course, in other embodiments of the present invention, the number of clamping seats 112 may be three, four, five, eight, etc., and there is no limitation on the specific number.

[0045] Please refer to Figure 1 and Figure 2 In order to ensure that the clamping seat 112 does not leave clamp marks on the milling cutter when clamping it, and to facilitate the clamping of milling cutters of different sizes, the conveying mechanism 110 may also include a flexible pad 113. The flexible pad 113 is installed at the front end of the clamping seat 112 and is used to support the milling cutter.

[0046] Of course, to ensure clamping force, the opening and closing dimensions of the clamping seat 112 can be adjusted by external force to prevent the milling cutter from falling off during the clamping and conveying process. The opening and closing of the clamping seat 112 can be controlled manually, electrically, or automatically by sensing; the specific control method is not limited.

[0047] Please refer to Figure 1 and Figure 3 The height adjustment mechanism 120 includes an adjustment frame 121, a lifting slider 122, and a support block 123. The lifting slider 122 is slidably engaged with the adjustment frame 121, and the support block 123 is connected to the lifting slider 122 and is used to hold the bottom end of the milling cutter.

[0048] When height adjustment is required, the lifting slider 122 can move up and down along the adjusting frame 121, synchronously driving the support block 123 to move up and down. The support block 123 holds the bottom end of the milling cutter to adjust the milling cutter to a suitable height. In order to reduce adjustment resistance, the clamping seat 112 can be slightly loosened during the height adjustment process.

[0049] It should be noted that when the clamping height of the milling cutter exceeds the appropriate height, the support block 123 can be moved to the lower side of the milling cutter first, and then the clamping seat 112 can be released, so that the milling cutter slowly falls onto the support block 123, and then the support seat drives the milling cutter to rise to the appropriate height.

[0050] Please refer to Figure 1 and Figure 3 In order to ensure the effective placement of the milling cutter during the lifting process and to prevent the milling cutter from deflecting, a limiting hole 1231 can be provided on the support block 123, and the side wall of the limiting hole 1231 forms a multi-level support step. The limiting hole 1231 is concentrically set with the milling cutter and is used to place the bottom end of the milling cutter.

[0051] Specifically, corresponding support steps can be designed according to the specifications and dimensions of different milling cutters, so that the inner diameter of the step matches the outer diameter of the bottom end of the milling cutter, and each step has a certain depth to make axial contact with the milling cutter and prevent the milling cutter from deflecting after the clamping seat 112 is released.

[0052] Please refer to Figure 1 and Figure 4 The first acquisition mechanism 130 includes a first mounting frame 131, a first camera 132, a light shield 133, and a fill light 134. The first camera 132, the light shield 133, and the fill light 134 are all connected to the first mounting frame 131. The first camera 132 and the fill light 134 are located inside the light shield 133. The light shield 133 is used to cover the milling cutter, and the first camera 132 is used to perform acquisition operations from the top side of the milling cutter.

[0053] In use, the first mounting bracket 131 is used to fix the first camera 132, the light shield 133 is used to shield the ambient light source so that the appearance inspection of the end face of the milling cutter is not affected by the ambient light source, and the supplementary light 134 is used to provide supplementary lighting effect inside the light shield 133 so that the milling cutter can be inspected under ideal lighting conditions, further improving the inspection effect.

[0054] Meanwhile, in order to ensure that the milling cutter can smoothly enter the light-shielding cover 133 without having to avoid it during the entry and exit process due to the presence of the light-shielding cover 133, notches 1331 can be formed on both sides of the light-shielding cover 133. The milling cutter is used to pass through the notches 1331 under the action of the conveying mechanism 110.

[0055] Please refer to Figure 1 and Figure 5 The second acquisition mechanism 140 includes a second mounting bracket 141, a sliding block 142, and a second camera 143. The sliding block 142 is slidably engaged with the second mounting bracket 141, and the second camera 143 is connected to the sliding block 142. The sliding block 142 is used to move the second camera 143 closer to or away from the milling cutter.

[0056] In use, the forward and backward slider 142 is used to slide along the second mounting bracket 141 to move the second camera 143 closer to or away from the milling cutter, so that the distance between the camera and the milling cutter can be adjusted when performing peripheral wall detection on the milling cutter, further improving the detection effect.

[0057] It should be noted that the forward and backward direction of the slider 142 can be understood as the radial direction of the rotating disk 111.

[0058] Please refer to Figure 1 and Figure 6 The rotary clamping mechanism 150 includes a lifting frame 151, a rotary drive component 152, a telescopic sleeve 153, and a rotary chuck 154. The rotary drive component 152, the telescopic sleeve 153, and the rotary chuck 154 are all housed inside the lifting frame 151 and connected in sequence. The rotary chuck 154 is connected to the top of the lifting frame 151. The lifting frame 151 is used for lifting and lowering to drive the telescopic sleeve 153 to extend and retract. The rotary drive component 152 is used to drive the rotary chuck 154 to clamp the milling cutter and drive the milling cutter to rotate.

[0059] When performing peripheral wall inspection on a milling cutter, the clamping seat 112 cannot directly drive the milling cutter to rotate. To ensure comprehensive inspection, the rotating clamping mechanism 150 can drive the milling cutter to rotate while clamping it.

[0060] When the clamping seat 112 moves the milling cutter close to the peripheral wall inspection station, the lifting frame 151 can be raised and lowered under external force to drive the rotating chuck 154 to rise and fall, allowing the rotating chuck 154 to rotate to a suitable opening and closing size to receive the milling cutter. Simultaneously, the telescopic sleeve 153 extends and retracts. When the milling cutter reaches the peripheral wall inspection station, the clamping seat 112 slowly releases, and the milling cutter slowly falls into the rotating chuck 154. At this time, the rotary drive 152 is activated to drive the rotating chuck 154 to rotate and clamp the milling cutter. Once clamped in place, the rotary drive 152 can continue to rotate, causing the rotating chuck 154 to drive the milling cutter to rotate synchronously, enabling a comprehensive inspection of the milling cutter's peripheral wall.

[0061] After the inspection is completed, the lifting frame 151 moves the milling cutter to the inside of the clamping seat 112, where the clamping seat 112 clamps it again, and then moves the milling cutter to the next station.

[0062] It should be noted that the rotary clamping mechanism 150 can rotate the bottom end of the telescopic sleeve 153 while rotating and clamping. Because the rotary chuck 154 is connected to the lifting frame 151, its exterior does not rotate directly. Instead, it rotates internally through a helical engagement with the telescopic sleeve 153, thereby clamping the milling cutter and driving the milling cutter to rotate synchronously.

[0063] Please refer to Figure 6 The lifting frame 151 includes an upper end plate 1511, a lower end plate 1512, an extension rod 1513, a friction spring 1514, a limiting piece 1515, and a locking member 1516. The extension rod 1513 consists of at least three sets, with both ends connected to the upper end plate 1511 and the lower end plate 1512, respectively. The limiting piece 1515 is disposed on the extension rod 1513. The extension rod 1513 passes through the upper end plate 1511. The locking member 1516 is connected to the extension rod 1513 and abuts against the upper side of the upper end plate 1511. The friction spring 1514 is sleeved on the extension rod 1513 and connected between the upper end plate 1511 and the limiting piece 1515. The rotating chuck 154 is connected to the upper end plate 1511. The rotating drive member 152 is connected to the lower end plate 1512. The telescopic sleeve 153 is located between the upper end plate 1511 and the lower end plate 1512.

[0064] The rotary clamping mechanism 150 also includes a friction ring 155 and a pressure block 156. The friction ring 155 and the pressure block 156 are respectively disposed on the upper and lower sides of the upper end plate 1511, and are both sleeved on the rotary chuck 154.

[0065] When assembling the rotary clamping mechanism 150, the upper end plate 1511 and the lower end plate 1512 can be connected by at least three sets of extension rods 1513 to accommodate the rotary drive component 152, the telescopic sleeve 153, and the rotary chuck 154 inside. When driving the milling cutter to rotate forward, the milling cutter is clamped or clamped in place. When it is necessary to release the milling cutter, to prevent excessively rapid release, the friction ring 155 can provide a certain friction buffer against the top of the rotary chuck 154 or the telescopic sleeve 153.

[0066] When the friction ring 155 buffers the telescopic sleeve 153, the upper end of the locking sleeve can rotate relative to the lower end, allowing multiple sets of matching protrusions and grooves to be provided on the peripheral walls of both the upper and lower ends. In forward rotation, the protrusions and grooves correspond and engage one-to-one, ensuring synchronous rotation of the upper and lower ends. In reverse rotation, the presence of the friction ring 155 causes the rotational speed of the upper end to lag behind that of the lower end, allowing the protrusions on the upper end to engage with the other grooves, ensuring the connection stability between the upper and lower ends while achieving differential rotation.

[0067] Furthermore, to further improve the control precision of the reversal rate, i.e., to precisely control the magnitude of the frictional resistance provided by the friction ring 155, the axial position of the upper end plate 1511 relative to the extension rod 1513 can be adjusted. During the adjustment process, the friction spring 1514 will always provide a pressing force to the upper end plate 1511, the limiting piece 1515 will press and limit the bottom end of the friction spring 1514, and the locking element is used to lock the upper side of the upper end plate 1511. Specifically, the locking element can be a nut, and the upper end of the extension rod 1513 is provided with a matching external thread.

[0068] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
