Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, specifically to a milling cutter edge forming grinding device. Background Technology

[0002] Milling cutters are one of the tools used in modern industry for machining workpieces. They can be used to process metals, wood, and other materials. They are mainly used to cut materials by rotating the cutter to manufacture parts and machine surfaces. The cutting edge of the milling cutter is the part of the milling cutter that directly participates in the cutting work. During the machining process, the grinding of the cutting edge is a complex and delicate process. Various problems may occur during the grinding process, which can affect the performance and service life of the milling cutter.

[0003] A search revealed, for example, a Chinese patent application with publication number CN218341646U, which discloses a grinding device for machining carbide end mills. The device involves starting a fourth motor to rotate a second threaded rod, which in turn drives two sets of second threaded sliders on its surface to move a top clamp towards the center. This facilitates the placement of carbide end mills with different hole spacings. The clamp is then moved in the opposite direction to a limiting block to secure the carbide end mill, preventing uneven grinding thickness caused by the movement of the end mill. Bolts are then inserted through two sets of bolt holes to secure the carbide end mill inside the clamp.

Detailed Implementation

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0020] This utility model provides, for example Figure 1-5 The milling cutter edge forming grinding device shown includes a device body 1, an L-shaped plate 2 fixedly connected to the back of the device body 1, and a top plate 3 fixedly connected to the top of the L-shaped plate 2.

[0021] To make the device compatible with milling cutters of different diameters, a rotating component 5 is provided on the top of the main body 1 of the device for rotating the milling cutter edge; like Figure 2As shown, the rotating assembly 5 includes a rotating disk 51, the bottom of which is located at the top of the main body 1. Multiple first grooves 53 are formed on the top of the rotating disk 51, and sliding blocks 58 are slidably connected within each groove 53. A lead screw 54 is rotatably connected to the interior of one of the grooves 53 via a bearing. A first servo motor 52 is fixedly connected to the outer wall of the rotating disk 51, and the output end of the first servo motor 52 is fixedly connected to the lead screw 54. The surface of the lead screw 54 is threadedly connected to the interior of one of the sliding blocks 58. First sliding plates 56 and second sliding plates 57 are equidistantly arranged inside the sliding blocks 58, and these plates are arranged intersectingly. One end of each sliding plate 56 and second sliding plate 57 is located inside another sliding block 58. Multiple first sliding plates 56 and second sliding plates 57 are formed on the top of the rotating disk 51. The second slide groove 55 has a first sliding block 56 and a second sliding block 57 that are slidably connected inside it. When the position of the sliding block 58 is not appropriate, the operator rotates the first servo motor 52. The rotation of the first servo motor 52 will cause the lead screw 54 to rotate, which will cause the sliding block 58 to move inward. The movement of the sliding block 58 will move the first sliding plate 56 and the second sliding plate 57 inward, and make the first sliding plate 56 and the second sliding plate 57 slide inward along the second slide groove 55. During the movement of the first sliding plate 56 and the second sliding plate 57, the remaining sliding block 58 will slide inward. Thus, when the first servo motor 52 rotates, it will move all four sliding blocks 58 towards the center at the same time, realizing the rapid adjustment of the position of the sliding block 58 and making it convenient to use.

[0022] To make the rotary disk 51 rotate, a second servo motor 8 is fixedly connected to the bottom center of the main body 1 of the device. The output end of the second servo motor 8 is fixedly connected to the bottom center of the rotary disk 51. After grinding one milling cutter edge, the second servo motor 8 is started. The rotation of the second servo motor 8 will rotate the rotary disk 51, thereby changing the position of the milling cutter and moving the other milling cutter edge below the grinding disk 453 to achieve grinding of the other milling cutter edge.

[0023] To facilitate quick removal and installation of the milling cutter, the top of the sliding block 58 is provided with a fixing component 6 for fixing the milling cutter edge; like Figure 3As shown, the fixing component 6 includes a fixing plate 61, which is snapped onto the top of the sliding block 58. A vertical plate 63 is fixedly connected to the rear end of the top of the fixing plate 61. A slide rail 64 is fixedly connected to the outer wall of the vertical plate 63. A telescopic rod 65 is fixedly connected to the top of the inner side of the slide rail 64. A lifting plate 69 is fixedly connected to the top of the telescopic rod 65. The lifting plate 69 is fitted and slidably connected inside the slide rail 64. A return spring 66 is sleeved on the surface of the telescopic rod 65. The two ends of the return spring 66 are fixedly connected to the top of the inner side of the slide rail 64 and the top of the lifting plate 69, respectively. When in use, the milling cutter is inserted above the fixing plate 61. The milling cutter will push the lifting plate 69 to move upward along the slide rail 64 and compress the telescopic rod 65 and the return spring 66, making it suitable for milling cutters of different thicknesses and fixing the milling cutter. When the milling cutter is removed, after the force on the lifting plate 69 disappears, the return spring 66 will rebound and simultaneously stretch the telescopic rod 65, causing the lifting plate 69 to move downward for convenient subsequent use.

[0024] To prevent the spring 66 from causing the lifting plate 69 to reciprocate, the outer wall of the fixed plate 61 is symmetrically fixed with a second ear plate 68, and the outer wall of the lifting plate 69 is provided with a first ear plate 67 located above the second ear plate 68. When fixing, the lifting plate 69 is fixed to the fixed plate 61 by inserting bolts into the first ear plate 67 and the second ear plate 68.

[0025] To fix the fixing plate 61 to the top of the sliding block 58, a fixing post 62 is symmetrically fixed to one end of the bottom of the fixing plate 61. The sliding block 58 has symmetrically opened positioning holes 59. The fixing post 62 is inserted into the positioning hole 59. Before use, the four corners of the milling cutter are fixed to the top of the fixing plate 61. Then, the fixing post 62 is aligned with the positioning hole 59 and inserted into the positioning hole 59. Then, the fixing plate 61 is placed on the top of the sliding block 58 to achieve snap-fit ​​positioning. When removing it, the operator pulls the fixing plate 61 outward to detach the fixing plate 61 from the sliding block 58 and removes the milling cutter from outside the device. This improves the safety of removing the milling cutter and prevents certain dangers to the health of the operator.

[0026] In order to enable the milling cutter edge to be ground according to the actual situation, a grinding mechanism 4 is fixedly connected to the top of the top plate 3 for grinding the milling cutter edge. like Figure 1 , Figure 4 , Figure 5As shown, the grinding mechanism 4 includes a linear module 41, a linear slider 42 slidably connected to the surface of the linear module 41, a telescopic cylinder 43 fixedly connected to the bottom center of the linear slider 42, and a grinding part 45 fixedly connected to the bottom telescopic end of the telescopic cylinder 43. The operator needs to start the linear module 41 according to the actual situation, adjust the longitudinal position of the grinding part 45, which needs to be determined according to the diameter of the milling cutter, and then start the telescopic cylinder 43 to move the grinding part 45 to the surface of the milling cutter for grinding.

[0027] like Figure 5 As shown, in order to achieve the grinding of the milling cutter, the grinding part 45 includes a protective housing 451. A rotary motor 452 is fixedly connected to the top of the inside of the protective housing 451. The bottom output end of the rotary motor 452 is located below the bottom of the protective housing 451. A grinding disc 453 is fixedly connected to the output end of the rotary motor 452. During grinding, the rotary motor 452 is started, and the rotation of the rotary motor 452 will cause the grinding disc 453 to rotate, thereby realizing the grinding operation of the milling cutter.

[0028] To make the movement of the telescopic cylinder 43 more stable, a hydraulic telescopic rod 44 is symmetrically fixedly connected to the bottom of the linear slider 42. The bottom telescopic end of the hydraulic telescopic rod 44 is fixedly connected to the top of the protective housing 451. When the telescopic cylinder 43 drives the grinding workpiece 45 to move, the hydraulic telescopic rod 44 will extend to limit the grinding workpiece.

[0029] To cushion the impact force generated by the collision when the sliding block 58 moves to the innermost side, a rubber block 7 is attached to one end of the sliding block 58. It should be noted that the back of the sliding block 58 is arc-shaped. When four sliding blocks 58 come into contact, the arc shape can form a circle, which will compress the rubber block 7 and buffer the cushioning force.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
