[0036] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0037] Please refer to Figure 1 The milling cutter appearance inspection device 100 provided in the embodiment of the present invention can solve the above problems, which 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 collecting mechanism 130, a second collecting mechanism 140 and a rotating clamping mechanism 150;

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

[0040] When working, the milling cutter appearance inspection device 100 can transport the milling cutter by the conveying mechanism 110, the height adjustment mechanism 120 is used to adjust the milling cutter to the inspection height, the first collection mechanism 130 performs end face appearance inspection on the milling cutter, and the second collection mechanism 140 cooperates with the rotating clamping mechanism 150 to perform peripheral wall inspection on the milling cutter. The end face and peripheral wall inspection of the milling cutter can be integrated, 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, and the conveying mechanism 110, the height adjustment mechanism 120, the first collection mechanism 130, the second collection mechanism 140 and the rotating clamping mechanism 150 can all 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 rotating disk 111 and a plurality of clamping seats 112. The plurality of clamping seats 112 are evenly arranged along the circumference of the rotating disk 111. The front ends of the clamping seats 112 protrude from the edge of the rotating disk 111 and are used to clamp the milling cutter.

[0043] In order to further improve the detection efficiency and realize the streamlined detection of the milling cutter, the height adjustment mechanism 120, the first collection mechanism 130 and the second collection mechanism 140 can be respectively corresponding to the clamping seat 112 of different stations, so that the milling cutter can be orderly adjusted in height, end surface detection and peripheral wall detection. The front end of the clamping seat 112 protrudes from the rotating disk 111, which is convenient for clamping a longer milling cutter, so that the bottom end of the milling cutter will not be interfered by the rotating disk 111.

[0044] In this embodiment, there are six clamping seats 112, and the rotating disk 111 simultaneously drives the six clamping seats 112 to rotate. Of course, in other embodiments of the present invention, the number of the clamping seats 112 can be three, four, five, eight, etc., and the specific number is not limited.

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

[0046] Of course, in order to ensure the clamping strength, the opening and closing size of the clamping seat 112 can be adjusted by external force to avoid the milling cutter falling during the process of clamping and conveying the milling cutter. The opening and closing of the clamping seat 112 can be controlled manually, electrically, or automatically, and 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 matched with the adjustment frame 121. The support block 123 is connected to the lifting slider 122 and is used to support the bottom end of the milling cutter.

[0048] When height adjustment is required, the lifting slider 122 can be lifted along the adjustment frame 121, and the support block 123 can be lifted and lowered synchronously, and the support block 123 can support the bottom end of the milling cutter to adjust the milling cutter to a suitable height. In order to reduce the 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, and then the clamping seat 112 can be released, so that the milling cutter first 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 accommodation effect of the milling cutter during the lifting process and avoid the deflection of the milling cutter, a limiting hole 1231 can be opened on the support block 123, and the side wall of the limiting hole 1231 is formed with multiple supporting steps. The limiting hole 1231 is used to be concentrically arranged with the milling cutter and to accommodate the bottom end of the milling cutter.

[0051] Specifically, corresponding supporting steps can be designed according to the specifications of different milling cutters, so that the inner diameter of the step is adapted to the outer diameter of the bottom end of the milling cutter, and each step has a certain depth to provide axial contact with the milling cutter to 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 shielding cover 133 and a fill light 134. The first camera 132, the light shielding cover 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 on the inner side of the light shielding cover 133. The light shielding cover 133 is used to cover the milling cutter, and the first camera 132 is used to perform acquisition operations from the upper side of the milling cutter.

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

[0054] At the same time, in order to allow the milling cutter to smoothly enter the light shielding cover 133 without having to avoid it during the entry and exit process due to the existence of the light shielding cover 133, recesses 1331 can be formed on both sides of the light shielding cover 133, and the milling cutter is used to pass through the recesses 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 frame 141, an advance-retract slider 142 and a second camera 143. The advance-retract slider 142 slidably cooperates with the second mounting frame 141. The second camera 143 is connected to the advance-retract slider 142. The advance-retract slider 142 is used to drive the second camera 143 to approach or move away from the milling cutter.

[0056] When in use, the advance and retreat slider 142 is used to slide along the second mounting frame 141 to drive the second camera 143 to move closer to or away from the milling cutter, so that the distance from the milling cutter can be adjusted when the milling cutter is inspected around the wall, further improving the inspection effect.

[0057] It should be noted that the advancing and retreating direction of the advancing and retreating sliding block 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 driving member 152, a telescopic sleeve 153 and a rotary chuck 154. The rotary driving member 152, the telescopic sleeve 153 and the rotary chuck 154 are all accommodated on the inner side of the lifting frame 151 and are 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 movement to drive the telescopic sleeve 153 to perform telescopic movement. The rotary driving member 152 is used to drive the rotary chuck 154 to clamp the milling cutter and drive the milling cutter to rotate.

[0059] When the milling cutter is inspected on the peripheral wall, the clamping seat 112 cannot directly drive the milling cutter to rotate. In order to ensure the comprehensiveness of the inspection, the rotary clamping mechanism 150 can drive the milling cutter to rotate while clamping the milling cutter.

[0060] When the clamping seat 112 drives the milling cutter to approach the peripheral wall detection station, the lifting frame 151 can be lifted and lowered under the action of external force to drive the rotating chuck 154 to lift and lower, and make the rotating chuck 154 rotate to a suitable opening and closing size to receive the milling cutter. At the same time of lifting and lowering, the telescopic sleeve 153 performs a telescopic action. When the milling cutter reaches the peripheral wall detection station, the clamping seat 112 is slowly released, and the milling cutter slowly falls into the rotating chuck 154. At this time, the rotating drive member 152 is started to drive the rotating chuck 154 to rotate and clamp the milling cutter. After clamping in place, the rotating drive member 152 can continue to rotate, so that the rotating chuck 154 drives the milling cutter to rotate synchronously, so as to perform a comprehensive inspection of the peripheral wall of the milling cutter.

[0061] After the detection is completed, the lifting frame 151 drives the milling cutter to move to the inner side of the clamping seat 112, re-clamps the clamping seat 112, and then drives the milling cutter to move to the subsequent workstation.

[0062] It should be noted that the rotating clamping mechanism 150 can drive the bottom end of the telescopic sleeve 153 to rotate while rotating and clamping. Because the rotating chuck 154 is connected to the lifting frame 151, its exterior does not rotate directly, but through the spiral cooperation with the telescopic sleeve 153, the interior of the rotating chuck 154 rotates, so as to clamp the milling cutter and drive 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 limit plate 1515 and a locking member 1516. The extension rod 1513 is at least three groups and the two ends are respectively connected to the upper end plate 1511 and the lower end plate 1512. The limit plate 1515 is arranged on the extension rod 1513, and 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 limit plate 1515. The rotating chuck 154 is connected to the upper end plate 1511, the rotating driving member 152 is connected to the lower end plate 1512, and the telescopic sleeve 153 is located between the upper end plate 1511 and the lower end plate 1512.

[0064] The rotating clamping mechanism 150 further 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 rotating clamp 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 groups of extension rods 1513, so as to accommodate the rotary drive member 152, the telescopic sleeve 153 and the rotary chuck 154 inside. When the milling cutter is driven to rotate forward, the milling cutter is clamped or clamped. When the milling cutter needs to be loosened, in order to avoid the loosening speed being too fast, the friction ring 155 can play a certain friction buffering role on 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 be rotated relative to the lower end, and multiple sets of matching protrusions and grooves can be set on the peripheral walls of the upper and lower ends. In the case of forward rotation, the protrusions and grooves correspond and cooperate one by one, so that the upper and lower ends rotate synchronously. In the case of reverse rotation, because the existence of the friction ring 155 can make the rotation rate of the upper end lag behind the rotation rate of the lower end, the protrusions on the upper end are matched with other grooves, and the connection stability of the upper and lower ends is ensured when differential rotation is achieved.

[0067] Furthermore, in order to further improve the control accuracy of the reversal rate, that is, to accurately control the magnitude of the friction 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 plate 1515 will press and limit the bottom end of the friction spring 1514, and the locking member is used to lock the upper side of the upper end plate 1511. Specifically, the locking member can be a nut, and the upper end of the extension rod 1513 is provided with a matching external thread.

[0068] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
