Detailed Implementation

[0027] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0028] Example 1: As Figures 1-6 As shown, this utility model provides a technical solution: an adjustable milling cutter machining positioning device, including a worktable 1, a movable hole 2 opened on the upper part of the worktable 1, a mounting plate 4 fixedly installed on the upper part of the worktable 1, a milling cutter fixing chuck 5 set on the upper part of the worktable 1, and a machining component 3 set on the upper part of the worktable 1. The machining component 3 includes a disassembly and assembly mechanism 31 set on the upper part of the worktable 1, an adjustment mechanism 32 set on the upper part of the worktable 1, and a grinder 311 fixedly installed on the right side of the mounting plate 4 via a base. The output end of the grinder 311 is fixedly connected to a mounting plate 312. A connecting plate 313 is provided on the left side of the plate 312. A convex post 314 is fixedly connected to the right side of the connecting plate 313. A snap-fit ​​groove 315 is opened on one side of the convex post 314. A grinding plate 316 is fixedly connected to the left side of the connecting plate 313. A convex groove 317 is opened on the left side of the mounting plate 312. An inner groove 318 is opened inside the mounting plate 312. A movable block 319 is slidably connected to the inner wall of the inner groove 318. A sloping snap-fit ​​block 3110 is fixedly connected to one side of the movable block 319. A spring 3111 is fixedly connected to the inner wall of the inner groove 318. A through hole is opened on one side of the mounting plate 312. A pull rod 3112 is slidably connected to the inner wall of the hole.

[0029] In this embodiment, the convex column 314 is slidably connected in the convex groove 317, and the inclined plate block 3110 is movably connected through the mounting plate 312 and the locking groove 315. One end of the spring 3111 is fixedly connected to the movable block 319. Through the cooperation of the convex column 314, the locking groove 315, the grinding disc 316, the convex groove 317, the inner groove 318, the movable block 319, the inclined plate block 3110, the spring 3111, and the pull rod 3112, it is convenient for manual replacement of the grinding disc 316 with large wear in a timely manner, so as to achieve a better grinding effect on the milling cutter and thus increase the applicability of the device.

[0030] Furthermore, the outer side of the movable block 319 is fixedly connected to the pull rod 3112.

[0031] When the grinding disc 316 needs to be disassembled, simply pull the lever 3112 manually to move the movable block 319 within the inner groove 318. This allows the inclined locking block 3110, fixedly connected to one side of the movable block 319, to separate from the locking groove 315. Subsequently, under the action of the convex column 314 and the convex groove 317, the connecting plate 313 can be removed outwards. This facilitates timely replacement of the heavily worn grinding disc 316, resulting in better grinding of the milling cutter and increasing the applicability of the device. Furthermore, when the grinding disc 316 needs to be installed, it can be manually installed by connecting the fixed plate 3110 to the inner groove 318. The convex post 314 on one side engages with the convex groove 317. When the convex post 314 moves into the convex groove 317 and presses against the inclined block 3110, the inclined block 3110 can be pressed into the inner groove 318 because its outer side is inclined. Then, when the convex post 314 and the convex groove 317 are fully engaged, the movable block 319 can drive the inclined block 3110 to rebound under the action of the spring 3111, so that the inclined block 3110 can engage with the locking groove 315, thereby fixing the convex post 314 in the convex groove 317, thus completing the installation operation.

[0032] Example 2: Based on Example 1, a preferred embodiment of the adjustable milling cutter machining positioning device provided by this utility model is as follows: Figures 1 to 6As shown: The adjustment mechanism 32 includes a first motor 321 fixedly mounted on the left side of the workbench 1 via a base. A lead screw 322 is fixedly connected to the output end of the first motor 321. A first connecting block 323 is threadedly connected to the outer wall of the lead screw 322. A limit rod 324 is fixedly connected to the inner wall of the movable hole 2. A second connecting block 325 is slidably connected to the outer wall of the limit rod 324. An adjustment plate 326 is fixedly mounted on the upper part of the second connecting block 325. A second motor 327 is fixedly mounted on the lower part of the adjustment plate 326 via a mounting bracket. The output end of the second motor 327 is fixedly connected to a rotating shaft 328. The top of the rotating shaft 328 is fixedly connected to a turntable 329. An installation rod 3210 is fixedly installed on the upper part of the turntable 329. A slide rail 3211 is fixedly installed on the lower part of the milling cutter fixing chuck 5. A slide rod 3212 is fixedly connected to the inner wall of the slide rail 3211. A slider 3213 is slidably connected to the outer wall of the slide rod 3212. A fixing block 3214 is movably connected to the lower part of the slider 3213 through a pin. An electric telescopic rod 3215 is fixedly installed on the upper part of the turntable 329.

[0033] In this embodiment, the top of the first connecting block 323 is fixedly connected to the mounting rod 3210, the rotating shaft 328 is rotatably connected through the bearing adjusting plate 326, and the lead screw 322 is rotatably connected to the worktable 1 through the bearing. Through the cooperation of the first motor 321, the lead screw 322, the first connecting block 323, the limiting rod 324, the second connecting block 325, the adjusting plate 326, the second motor 327, the rotating shaft 328, the turntable 329, the mounting rod 3210, the slide rail 3211, the slide rod 3212, the slider 3213, the fixing block 3214, and the electric telescopic rod 3215, the milling cutter fixing chuck 5 can be rotated and adjusted, thereby allowing the fixed milling cutter to be rotated and adjusted. This allows the contact angle between the milling cutter and the grinding disc 316 to be adjusted, enabling multi-angle grinding of the milling cutter and making it sharper, thus increasing the applicability of the device.

[0034] Furthermore, the mounting rod 3210 is rotatably connected to the milling cutter fixing chuck 5, and the output end of the electric telescopic rod 3215 is fixedly connected to the fixing block 3214.

[0035] When the milling cutter needs to be ground, it is first manually fixed in the milling cutter chuck 5. Then, the first motor 321 drives the lead screw 322 to rotate clockwise. Under the limiting action of the first connecting block 323 and the limiting rod 324, the first connecting block 323, which is threaded onto the outer wall of the lead screw 322, moves the adjusting plate 326 to the right, thereby allowing the milling cutter to move synchronously to the right. Then, the grinding machine 311 drives the mounting plate 312 to rotate, and the milling cutter can be ground by the grinding plate 316. The second motor 327 drives the rotating shaft 328 to rotate, which causes the turntable 329, which is fixedly connected to the upper part of the rotating shaft 328, to rotate synchronously, thereby allowing the milling cutter to be ground. After being fixed, the milling cutter is adjusted by rotating horizontally. Furthermore, the fixed block 3214 is moved upward or downward by the electric telescopic rod 3215. Since the fixed block 3214 is movably connected to the slider 3213 through the pin, the slider 3213 can slide within the slide rail 3211 through the slide rod 3212. This allows the milling cutter fixing chuck 5 to be pressed upward or pulled downward. Since the milling cutter fixing chuck 5 is rotatably connected to the mounting rod 3210, the fixed milling cutter can be adjusted by rotating vertically. By adjusting the tilt angle of the milling cutter, it can be ground at multiple angles, making the milling cutter sharper and increasing the applicability of the device.
