Description

Technical Field

[0001] This utility model belongs to the technical field of milling cutter grinding, specifically relating to a milling cutter grinding device and milling cutter processing equipment. Background Technology

[0002] Milling cutter grinding equipment is a specialized tool used to repair and restore the precision of the cutting edge of milling cutters. It is primarily used for regrinding and edge treatment of milling cutters to restore or improve their cutting performance, extend tool life, and increase machining efficiency and quality. During the grinding process, grinding debris falls directly onto the equipment. Machine vibrations during grinding can dislodge accumulated debris onto the ground, requiring manual cleaning, which is particularly inconvenient for smaller debris.

[0003] For example, Chinese utility model patent (authorization announcement number: CN220881611U) discloses a grinding device and a precision milling cutter processing equipment, including: a clamping device is provided on the surface of the main body of the grinding device, a storage box is provided on the surface of the main body of the grinding device, a screw is provided on the side of the clamping device, a support plate is screwed to the surface of the screw, and a clamping plate is provided above the support plate; the beneficial effect is that when it is necessary to grind the milling cutter, the milling cutter is first fixed by the clamping device, then the main body of the grinding device is started, and then the grinding disc can be used to grind the surface of the milling cutter. The grinding debris can fall directly into the storage box. When there is a lot of debris in the storage box, the storage box can be pulled out from the slide for centralized processing, which is more convenient.

[0004] However, when the aforementioned grinding device and precision milling equipment grind milling cutters, the chips still fly everywhere. The space of the sodium storage box is too small, and it can only collect some of the chips. A large amount of chips still fall out, and the chip collection effect is not good. In addition, the range of motion of the clamping device is limited, and it is impossible to grind the milling cutter in multiple directions and angles.

[0005] Therefore, it is necessary to design a new solution to address the aforementioned problems. Utility Model Content

They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0024] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0025] In one embodiment of this utility model, such as Figure 1 , Figure 3-7 and Figure 9 As shown, a milling cutter grinding device is provided, including a support plate 1 with support feet 11 at the bottom of its four corner edges. A first feed mechanism 21 is mounted on the support plate 1, a second feed mechanism 22 is mounted on the first feed mechanism 21, an adapter plate 23 is mounted on the second feed mechanism 22, the bottom surface of a rotating mechanism 24 is mounted on the adapter plate 23, a third feed mechanism 25 is mounted on the top surface of the rotating mechanism 24, and a clamping mechanism 26 is mounted on the third feed mechanism 25. The clamping mechanism 26 includes a chuck 261 for mounting a milling cutter 3. The first feed mechanism 21, the second feed mechanism 22, and the third feed mechanism 25 are perpendicular to each other, allowing control of the movement of the milling cutter 3 in three-dimensional space. The rotating mechanism 24 allows control of the rotation of the milling cutter 3 in the horizontal direction. A grinding mechanism 4 is mounted on one side of the milling cutter 3, and the grinding mechanism 4 includes a grinding wheel 41 aligned with the milling cutter 3.

[0026] Specifically, the three-feed mechanisms (21, 22, and 25) adopt a common machine tool lead screw transmission system and guide rail support structure, allowing free adjustment of the coordinates of the milling cutter 3 in three-dimensional space; the rotary mechanism 24 adopts a rotary drive structure, and the rotary drive used in this application is a worm gear rotary drive, such as... Figure 4 As shown, the structure includes a housing 240, a turbine turntable 241, a worm gear 242, and a drive shaft 243. This structure is prior art, and its internal structure will not be described in detail here. This application uses a manual wheel fixedly connected to the drive shaft 243 to drive the worm gear to rotate. The bottom of the third feed mechanism 25 is provided with a connecting shaft fixedly connected to the turbine turntable 241. When the manual wheel is rotated, the third feed mechanism 25 can rotate as a whole, allowing the milling cutter 3 to rotate on the horizontal plane where the milling cutter 3 is located. This enables multi-angle and multi-directional adjustment of the milling cutter 3, which is beneficial for grinding each cutting edge when grinding the milling cutter 3.

[0027] The first feed mechanism 21, the second feed mechanism 22, the third feed mechanism 25, and the grinding mechanism 4 are surrounded by a sealing cover 5. The sealing cover 5 and the support plate 1 form a sealed space, which prevents the milling cutter 3 from scattering and flying, and collects all the debris within the sealed space, resulting in better debris collection. The sealing cover 5 is equipped with a guide rail 51, and a sliding door 52 is installed on the guide rail 51 and can slide inside it. The side wall of the sealing cover 5 has an opening adapted to the sliding door 52. Opening the sliding door 52 allows personnel to enter for work, and closing the sliding door 52 forms a sealed space.

[0028] A chip frame 12 is provided on the support plate 1. The chip frame 12 is a cone shape with its opening facing upwards. The chip frame 12 is located directly below the milling cutter 3 and the grinding wheel 41, and is used to collect most of the chips generated when grinding the milling cutter 3. A material leakage hole 13 is provided through the support plate 1, which is located inside the chip frame 12. A drawer 6 is provided below the support plate 1. The vertically downward projection area of ​​the material leakage hole 13 is located inside the drawer 6. After being collected by the chip frame 12, the chips fall into the drawer 6 through the material leakage hole 13 for convenient centralized processing. The drawer 6 can be pulled out or pushed in from the front and back. The support feet 11 are provided with limiting baffles 14, which are located on the left, right and rear sides of the drawer 6, and are used to limit the direction and range of movement of the drawer 6, ensuring that the upper part of the middle part of the drawer is directly above the material leakage hole 13.

[0029] The support plate 1 has several auxiliary through holes 16 extending through the bottom surface of the support plate 1 within the projection area of ​​the inner wall of the sealing cover 5. An air gun 53 is installed on the vertical inner wall of the sealing cover 5. The air gun 53 is used to blow away the scattered debris that flies out during the grinding of the milling cutter 3. The debris falls into the drawer 6 through the auxiliary through holes 16 for centralized processing, making the collection and cleaning of grinding debris more thorough.

[0030] Furthermore, such as Figure 3 , Figure 6 and Figure 10 As shown, the second feeding mechanism 22 includes a second guide plate 221, and a positioning mechanism 7 is installed on the second guide plate 221 and the adapter plate 23.

[0031] The positioning mechanism 7 includes a mounting block 71, an H-shaped block 72, a damping sleeve 73, two gaskets 74, and two connecting rods 75. The mounting block 71 is mounted on the side of the second guide plate 221 and the adapter plate 23.

[0032] Mounting block 71 has a hinge portion 711 with a mounting block hinge hole 7111. Damping sleeve 73 is inserted into the mounting block hinge hole 7111. H-block 72 has two rotating portions 722 with H-block rotating holes 7221. Two connecting rods 75 pass through the H-block rotating holes 7221 and are detachably connected to the damping sleeve 73, allowing H-block 72 to be hinged to mounting block 71 and thus rotate around mounting block 71. Two washers 74 are aligned and installed on both sides of the mounting block hinge hole 7111 and sleeved on the connecting rods 75, providing a damping effect when rotating H-block 72 and preventing excessively rapid and violent impacts on other components. Specifically, the gasket 74 is a copper flat gasket, the connecting rod 75 is a countersunk screw, the damping sleeve 73 is a sleeve structure and the inner wall is provided with a threaded hole that matches the connecting rod 75, and the H-block rotating hole 7221 is provided with a tapered countersunk hole.

[0033] The third feed mechanism 25 includes a third guide plate 251. The H-block 72 is also provided with two limiting parts 721. The two limiting parts 721 are used to limit the two sides of the third guide plate 251 in the thickness direction to position the third feed mechanism 25, which can improve the positioning performance and machining stability of the milling cutter 3.

[0034] The mounting block 71 is also provided with two support parts 712. When the H-shaped block 72 rotates around the axis of the mounting block hinge hole 7111 until the two limiting parts 721 are located on both sides of the thickness direction of the third guide plate 251 and the length direction of the H-shaped block 72 is perpendicular to the feeding direction of the third feeding mechanism 25, the support parts 712 support the H-shaped block 72 and limit the movement of the H-shaped block 72, so as to prevent the H-shaped block 72 from automatically rotating to a position that cannot limit the third guide plate 251.

[0035] Furthermore, such as Figure 10 As shown, the two limiting parts 721 are provided with anti-slip pad grooves 7211, and anti-slip pads 76 are installed in the two anti-slip pad grooves 7211. The anti-slip pads 76 are wedge-shaped. When the length direction of the H-shaped block 72 is parallel to the feeding direction of the third feeding mechanism 25, the anti-slip pad 76 is thinner on the side near the third guide plate 251 and thicker on the other side, so that the H-shaped block 72 and the third guide plate are locked more tightly and the positioning effect is better. At the same time, the anti-slip pads 76 are made of rubber, which also avoids rigid contact that could damage the parts.

[0036] Furthermore, such as Figure 4 As shown, the support plate 1 has a material leakage channel 15 that runs through the bottom surface. The material leakage channel 15 is located on the front and rear sides of the area where the top surface of the support plate 1 meets the inner wall of the sealing cover 5, which is conducive to debris falling into the drawer 6 from more channels.

[0037] Furthermore, such as Figure 9As shown, the sealing cover 5 has inclined plates 54 on all four sides of its vertical inner wall. The four inclined plates 54 are sealed together to form an upwardly angled opening. The tops of the four inclined plates 54 are sealed to the inner wall of the sealing cover 5. The bottoms of the two left and right inclined plates 54 are sealed to the support plate 1. The bottoms of the two front and rear inclined plates 54 are located in the middle area of ​​the material leakage channel 15 in the front-rear direction. The inclined plates 54 facilitate the sliding of debris into the drawer 6 and also make it easier to use the air gun 53 to blow away the corner areas.

[0038] Furthermore, such as Figure 1 As shown, drawer 6 has a handle 61 on the outside for easy pushing and pulling of drawer 6.

[0039] Furthermore, such as Figure 1 As shown, drawer 6 is equipped with casters 62 on the bottom, making it faster and easier to push and pull drawer 6.

[0040] Furthermore, such as Figure 1 and Figure 11 As shown, the sliding door 52 has door handles 521 on both the inner and outer sides to facilitate sliding.

[0041] Furthermore, such as Figure 9 and Figure 11 As shown, several pulleys 511 are installed at intervals inside the upper and lower guide rails 51, making it faster and easier to slide the sliding door.

[0042] In an embodiment of this utility model, a milling cutter processing device includes the above-mentioned milling cutter grinding device.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
