Description

Technical Field

[0001] This utility model relates to the field of milling cutter installation technology, specifically to an adjustable angle alloy milling cutter positioning and installation device. Background Technology

[0002] The cutting tools commonly used in milling operations are called milling cutters. A milling cutter is a rotating cutting tool with one or more cutting teeth. During operation, each cutting tooth sequentially and intermittently removes the excess material from the workpiece. Milling cutters are mainly used on milling machines to machine planes, steps, grooves, shaped surfaces, and cut off workpieces. Disc milling cutters, as a type of face milling cutter, are mainly used for cutting stepped surfaces and grooves. When machining mechanical parts, milling cutter discs mounted on corresponding machine tools are often used to machine the surfaces of the parts, thereby ensuring that the machined parts have high-precision planes.

[0003] Chinese patent CN221247064U discloses an easy-to-install milling cutter disc, solving the problems of inconvenient installation and inability to adjust the cutting tool in existing technologies. The disc includes a spindle and a milling cutter disc. A limit assembly is installed inside the milling cutter disc. A fixed block is hinged inside the spindle, and one side of the fixed block is fixedly connected to the limit block by screws. A transmission block is slidably assembled inside the spindle, and a threaded rod is threadedly connected inside the transmission block. A second gear is fixedly connected to the top of the threaded rod by screws. Through the design of a locking block and a slot, the milling cutter disc is fitted onto the spindle. Rotating a knob rotates the first gear, which in turn rotates the second gear, which in turn rotates the threaded rod. The threaded rod causes the transmission block to rise and fall, opening the locking block and engaging it in the slot, thus completing the installation.

[0004] However, the following drawbacks still exist:

[0005] The cutting blades are all fixedly mounted on the tool holder, and their cutting angle is fixed. The milling cutter needs to be replaced for different processing needs and cutting angles, which is quite cumbersome. Utility Model Content

[0027] Example

[0028] This embodiment provides an adjustable angle alloy milling cutter positioning and mounting device, such as... Figures 1-4 As shown, it includes: a rotating shaft 100, a tool holder 110 mounted on the surface of the rotating shaft 100, a plurality of milling cutters 120 evenly distributed on the tool holder 110, and an adjustment mechanism 200 for adjusting the angle of the milling cutters 120; the adjustment mechanism 200 includes a bearing 210 rotatably connected inside the tool holder 110, a connecting plate 211 rotatably connected to the bearing 210, a mounting slot corresponding to the number of milling cutters 120 on the tool holder 110, an adjustment frame 212 rotatably connected in the mounting slot, the milling cutters 120 being fixedly connected to the adjustment frame 212 by fixing bolts, a slider being slidably connected to the surface of the adjustment frame 212, and the slider being rotatably connected to the connecting plate 211.

[0029] An adjustable-angle alloy milling cutter positioning and mounting device using the above technical solution is provided with an adjustment mechanism 200. The rotary bearing 210 drives the connecting plate 211 to rotate. Through the final rotation of the connecting plate 211 and the limiting action of the slide groove 213 and the slider, the adjustment frame 212 rotates in the mounting groove, thereby adjusting the angle of the milling cutter 120 mounted on the adjustment frame 212. This allows for easy adjustment of the angle of the milling cutter 120 as needed, making it convenient to use. The locking seat 321 is fixed to the positioning frame 320 by the limiting bolt, thereby keeping the position of the bearing 210 locked and preventing the milling cutter 120 from shaking during machining.

[0030] To achieve synchronous adjustment and rotation of multiple adjusting frames 212, symmetrical grooves 213 are provided on the upper and lower sides of the adjusting frame 212, and the slider is slidably connected in the groove 213. When the outer ring of the bearing 210 rotates, the connecting plate 211 drives the slider to slide along the groove 213, and the adjusting frame 212 rotates synchronously under the action of the mounting groove.

[0031] To lock the angle of the adjusting bracket 212, a locking mechanism 300 for locking the milling cutter 120 is provided on the tool holder 110. The locking mechanism 300 includes a through groove 310 formed on the top of the tool holder 110, and a locking seat 321 is slidably connected in the through groove 310. The locking seat 321 is fixedly connected to the top of the bearing 210. An angle mark is provided on the top of the through groove 310. Rotating the locking seat 321 causes the outer ring of the bearing 210 to rotate. With the cooperation of the locking seat 321 and the angle mark, the current angle is known.

[0032] To further ensure the stability of the sliding of the locking seat 321, a positioning frame 320 is fixedly connected inside the through groove 310, and a limiting through groove corresponding to the positioning frame 320 is provided on the locking seat 321. The locking seat 321 rotates along a set direction through the mutual cooperation of the limiting through groove and the positioning frame 320.

[0033] To lock the position of the adjusting frame 212, a limiting hole is provided on the locking seat 321, and multiple limiting holes are also evenly provided on the top of the positioning frame 320. A limiting bolt corresponding to the limiting hole is threaded onto the locking seat 321. Aligning the limiting hole of the locking seat 321 with the corresponding limiting hole of the positioning frame 320, and screwing in the limiting bolt, the position of the adjusting frame 212 is locked, ensuring the machining accuracy of the milling cutter 120.

[0034] To ensure stability when adjusting the angle of the adjusting bracket 212, the cross-section of the slide 213 is T-shaped, and the slider is matched with a T-shaped slider. The T-shaped slider has an anti-torsional design, is suitable for heavy cutting conditions, and improves high rigidity load-bearing capacity.

[0035] To improve the locking effect and prevent the limit bolts from falling off due to processing vibration, the end of the limit bolt is provided with an anti-loosening rubber layer, and the inner wall of the limit hole is machined with anti-slip texture.

[0036] In summary, the adjustable angle alloy milling cutter positioning and mounting device provided in this embodiment has the following advantages: An adjustment mechanism 200 is provided, and the rotating bearing 210 drives the connecting plate 211 to rotate. Through the final rotation of the connecting plate 211 and the limiting action of the sliding groove 213 and the slider, the adjustment frame 212 rotates within the mounting groove, allowing for angle adjustment of the milling cutter 120 mounted on the adjustment frame 212. This facilitates adjusting the angle of the milling cutter 120 as needed, making it convenient to use. The locking seat 321 is fixed to the positioning frame 320 by the limiting bolt, thereby keeping the bearing 210 in a locked position and preventing the milling cutter 120 from shaking during machining.

[0037] In use, loosen the limiting bolt of the locking mechanism 300, manually rotate the locking seat 321, causing the outer ring of the bearing 210 to rotate. The connecting plate 211 pushes the slider to slide along the T-shaped groove 213 of the adjusting frame 212. The slider applies a tangential force to the side wall of the groove 213, forcing the adjusting frame 212 to rotate around the axis of the mounting groove. All adjusting frames 212 rotate synchronously, realizing the linkage adjustment of the angles of multiple milling cutters 120. Observe the angle scale on the positioning frame 320 to confirm the target angle, align the limiting hole of the locking seat 321 with the corresponding limiting hole of the positioning frame 320, and screw in the limiting bolt. The anti-loosening rubber layer and the anti-slip texture are used to tighten it. Single-action synchronous adjustment of the angles of all milling cutters 120 shortens the adjustment time and facilitates use.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
