Description

Technical Field

[0001] This application belongs to the technical field of tool grinding equipment, and particularly relates to a grinding device and processing method for a double-edged milling cutter used in wood processing. Background Art

[0002] Wood boards are a commonly used raw material in the home furnishing field. By performing cutting and other fine processing on specified wood, well-made wood boards can be obtained, thereby providing raw materials for household products. Currently, there are many forms of tools used for wood board processing, including a long-strip tool with a straight cutting edge and bearings installed at the ends, which is mainly used for trimming the edges of wood boards during processing. Such tools have the advantages of fast rotation and clean cutting, and naturally also require an automatic grinding machine for grinding and maintenance.

[0003] The existing Chinese patent with the publication number CN110328564A discloses a milling cutter grinding device and its usage method, including a first grinding assembly and a second grinding assembly that are connected to a first driving mechanism and can move towards or away from each other in a first direction. A tool movement assembly is provided between the first grinding assembly and the second grinding assembly, and the tool movement assembly is connected to a second driving mechanism and can move in a second direction perpendicular to the first direction.

[0004] The above-mentioned milling cutter grinding device solves the problem of bending deformation of the milling cutter during the grinding process by setting two grindings. However, the above-mentioned wood processing milling cutter has a straight cutting edge and is not rotationally ground during grinding. A high parallelism is required between the cutting edge of the cutting edge and the axis of the tool holder to ensure that a vertical surface can be processed on the side of the wood board by using this milling cutter. Summary of the Invention

[0005] The purpose of this application is to address the above-mentioned existing technical problems by providing a grinding device for a double-edged milling cutter used in wood processing, improving the parallelism between the axis of the double-edged milling cutter after clamping and the axis of the grinding device, and ensuring a high parallelism between the cutting edge of the milling cutter and the axis of the tool holder.

[0006] This application provides a grinding device for a double-edged milling cutter used in wood processing, including:

[0007] A clamping device for clamping the milling cutter;

[0008] A grinding device placed on both sides of the clamping device;

[0009] A moving device for moving the clamping device and the grinding device;

[0010] A positioning device for milling cutter installation and positioning;

[0011] Among them, the moving device includes a first sliding seat, and the clamping device and the positioning device are placed at both ends of the first sliding seat.

[0012] The double-edged milling cutter is clamped by a clamping device. During the clamping process, the milling cutter is positioned and adjusted by a positioning device to ensure that the axis of the milling cutter is parallel to the axis of the grinding device, and to ensure that the cutting edge of the milling cutter is parallel to the axis of the tool shank after grinding. This ensures that when the processed milling cutter is used for edge cleaning, a flat and perpendicular plane can be machined on the side of the wooden part. The clamping device and the grinding device are moved by a moving device. The clamping device and the grinding device are installed on the first slide seat, and the milling cutter is clamped between the clamping device and the grinding device during machining.

[0013] Furthermore, the positioning device includes:

[0014] A positioning seat provided with a positioning groove;

[0015] A worm, movably installed on the positioning seat, and the worm is provided with a handle;

[0016] A swivel ring, installed on the positioning seat;

[0017] A worm gear, installed on the swivel ring;

[0018] Clamping members, installed on the positioning seat and evenly distributed around the axis of the positioning groove;

[0019] A knocking mechanism, placed on the clamping members;

[0020] Wherein, the swivel ring is provided with a plurality of sliding grooves, and the clamping members are provided with sliding blocks adapted to the sliding grooves.

[0021] The positioning seat is installed on the first slide seat, and the bearing on the milling cutter is adapted to the positioning groove. This facilitates the grinding of the milling cutter after it has been used for a period of time without having to remove the bearing, improving the convenience of grinding. Rotate the handle to make the worm rotate, and the worm drives the worm gear to rotate, controlling the rotation of the swivel ring. The clamping members are installed on the positioning seat, and the axis of the clamping members is perpendicular to the axis of the positioning groove. When the swivel ring rotates, through the connection structure between the sliding groove and the sliding block, the sliding block moves in the sliding groove. After the bearing is placed in the positioning groove, the clamping members move towards the bearing. When the milling cutter needs to be removed, the clamping members move away from the bearing. Before the bearing is completely clamped by the positioning device, the outer wall of the bearing is knocked by the knocking mechanism first to make the axis of the clamped bearing the same as the axis of the positioning groove, and then the bearing is clamped by the clamping members.

[0022] Furthermore, the knocking mechanism includes:

[0023] A knocking piece;

[0024] A first spring, placed between the knocking piece and the clamping member;

[0025] A pushing block, installed on the knocking piece;

[0026] Among them, the clamping piece is provided with a telescopic hole, the knocking piece is inserted in the telescopic hole, the clamping piece is provided with a movable groove, the pushing block is installed in the movable groove, the pushing block is provided with an installation groove, the first spring is installed in the installation groove, and the positioning seat is provided with a toggle seat, and the toggle seat is used to toggle the pushing block to move.

[0027] The knocking piece is installed on the clamping piece and contracts and moves in the telescopic hole. The pushing block is pushed to move away from the bearing through the toggle seat. Then, when the toggle seat releases the pushing block, the knocking piece is pushed to knock toward the bearing under the action of the first spring. After multiple knocks by the knocking piece, the axis of the bearing moves to coincide with the axis of the positioning groove. The pushing block is placed in the movable groove and partially extends outside the clamping piece through the movable groove to facilitate cooperation with the toggle seat. The first spring is installed in the mounting groove. When the pushing block moves to the end of the movable groove, the first spring is hidden in the mounting groove. At this time, the bearing is clamped by the clamping piece.

[0028] Furthermore, the toggle seat comprises:

[0029] A roller, mounted on the toggle seat and adapted to the push block;

[0030] The limiting mechanism is placed between the toggle seat and the positioning seat;

[0031] A second spring is placed between the toggle seat and the positioning seat;

[0032] There are two or more rollers in an even number and the rollers are evenly distributed around the axis of the toggle seat, and the diameter of the rollers is smaller than the minimum spacing between adjacent pushing blocks.

[0033] The toggle seat is movably installed on the positioning seat, and the roller is installed on the outer surface of the end of the toggle seat. When the toggle seat rotates, the roller rotates around the axis of the toggle seat. During the rotation of the roller, the pushing block it contacts is pushed and then released to realize the knocking function. The toggle seat realizes a stable installation structure through the second spring and the limiting mechanism. When the pushing block needs to be pushed, the position of the toggle seat is limited so that the roller and the pushing block are in the same plane for easy contact. When the push rod does not need to push the block, the toggle seat is controlled to stay away from the pushing block.

[0034] Furthermore, the limiting mechanism includes:

[0035] Limit axis;

[0036] The movable groove is placed on the positioning seat and has two movable grooves of different lengths, and the two movable grooves are connected to each other;

[0037] A movable seat, adapted to the movable groove, wherein the movable seat is in an I-shape;

[0038] A sliding member is mounted on the limiting shaft;

[0039] An annular groove is disposed on the toggle seat and is adapted to the sliding member;

[0040] Wherein, the limiting shaft is installed on the moving seat.

[0041] The sliding part is installed on the limit shaft, and the sliding part is adapted to the annular groove. When the toggle seat rotates, the sliding part slides in the annular groove. The moving groove is n-shaped, with one side long and the other side short. When the position of the toggle seat needs to be changed, the toggle seat is pushed to move for conversion. During the conversion, the limit shaft moves in the moving groove through the moving seat. The moving groove and the moving seat keep the axis of the limit shaft and the axis of the toggle seat always perpendicular to each other, ensuring that the sliding part is always adapted to the annular groove. The movement of the toggle seat on the axis is limited by the limit shaft, the sliding part and the annular groove.

[0042] Furthermore, the grinding device comprises:

[0043] Drive motor;

[0044] The grinding wheel is mounted on the output shaft of the driving motor.

[0045] The grinding device drives the grinding wheel with a motor of the same specification to rotate, and the high-speed rotation of the grinding wheel acts on the blade to grind the blade.

[0046] Furthermore, the mobile device also includes:

[0047] A first slide rail adapted to fit the first slide seat;

[0048] A first screw rod, matched with a first slide seat;

[0049] Second slide;

[0050] A second slide rail adapted to fit the second slide seat;

[0051] A second screw rod adapted to the second slide seat;

[0052] Wherein, the grinding device is installed on the second slide seat.

[0053] The first slide is adapted to the first slide rail, and the first slide moves on the first slide rail. The first screw rod cooperates with the first slide, and the movement of the first slide is controlled by rotating the first screw rod. The first screw rod is driven to rotate manually or by a motor. The second slide is adapted to the second slide rail, and the second slide moves on the second slide rail. Each grinding device corresponds to a separate second screw rod to realize separate control of the second slide. The second screw rod is driven to rotate manually or by a motor.

[0054] The present application also provides a method for processing a sharpening device for a double-edged milling cutter for wood processing, the specific steps comprising:

[0055] S1. Place the bearing on the milling cutter in the positioning groove, pre-clamp the shank of the milling cutter through the clamping device, and move the clamping member into the positioning groove by rotating the handle until it abuts against the bearing.

[0056] S2. Push the toggle seat to move the moving seat into the shorter moving groove at the same time, so that the roller and the pushing block are in the same plane. Rotate the pushing block to make the knocking member knock the bearing, so that the axis of the milling cutter is parallel to the axis of the grinding wheel.

[0057] S3. After completing the knocking and positioning, the clamping device clamps the shank. Continue to rotate the worm on the positioning device to move the clamping member and make the pushing block abut against the end of the movable groove, and clamp the bearing through the positioning device.

[0058] S4. Control the grinding device to move to the machining position through the moving device, and then move the clamping device through the moving device, so that the grinding device grinds the entire cutting edge. After grinding, the grinding device and the clamping device are reset through the moving device to release the clamping of the milling cutter.

[0059] Before the grinding process of the milling cutter, one end of the milling cutter is pre-clamped through the clamping device, and the other end is pre-clamped through the positioning device. Then, the axis of the milling cutter is adjusted through the positioning device, and then clamped through the clamping device and the positioning device to achieve high-precision machining of the grinding device.

[0060] The beneficial effects of this application are as follows:

[0061] 1. The double-edge milling cutter is clamped through the clamping device, and the milling cutter is positioned and adjusted through the positioning device during the clamping process to ensure that the cutting edge is parallel to the axis of the shank after grinding, so that the processed milling cutter can machine a flat and perpendicular plane on the side of the wood part when using it for edge cleaning.

[0062] 2. Rotate the handle to make the worm rotate. The worm drives the worm wheel to rotate and controls the rotation of the rotating ring. When the rotating ring rotates, through the connection structure between the sliding groove and the slider, the slider moves in the sliding groove. Before the bearing is completely clamped by the positioning device, the outer side wall of the bearing is knocked by the knocking mechanism to make the axis of the clamped bearing the same as the axis of the positioning groove, and then the bearing is clamped by the clamping member.

[0063] 3. Push the pushing block to move away from the bearing by the toggle seat. Then, when the toggle seat releases the pushing block, the knocking member is pushed to knock against the bearing under the action of the first spring. After the knocking member knocks several times, the axis of the bearing moves to coincide with the axis of the positioning groove.

[0064] 4. When the toggle seat rotates, the roller rotates around the axis of the toggle seat. During the rotation of the roller, the contacted pushing block is pushed and then released to achieve the knocking function. The toggle seat realizes a stable installation structure through the second spring and the limiting mechanism. BRIEF DESCRIPTION OF THE DRAWINGS
