Description

Technical Field

[0001] This application relates to the technical field of cutting tool processing, and in particular to a milling cutter edge grinding device. Background Technology

[0002] A milling cutter edge grinding device is a device that uses precision grinding technology to dress and repair the cutting edge of a milling cutter. Its core function is to restore the geometry, surface finish, and sharpness of the cutting edge, thereby improving the cutting performance and service life of the tool.

[0003] In related technologies, please refer to Chinese utility model patent with authorization announcement number CN218194107U, which discloses a milling cutter sharpening device, including a base, a fixed seat and a slide seat arranged adjacent to each other on the base, a drive component for driving the slide seat to move closer to or away from the fixed seat, a clamping component arranged on the fixed seat, a cutting edge changing component for driving the clamping component to rotate, and a controller arranged on the base. A grinding disc is arranged on the slide seat, a grinding motor is used to drive the grinding disc to rotate for grinding, and the clamping component is used to clamp the milling cutter blade to be sharpened. The drive component, clamping component, cutting edge changing component and grinding motor are all electrically connected to the controller.

[0004] However, in actual operation, the milling cutter sharpening device described above has a very limited angle to be sharpened when the milling cutter is held and sharpened by the rotating plate because the position of the grinding disc is fixed and the rotating plate can only rotate in one direction. To fully sharpen the milling cutter, the operator needs to continuously remove the milling cutter from the two rotating plates and adjust the angle at which the milling cutter is held on the rotating plate, which is very inconvenient. Moreover, it is difficult to control the rotation angle required for manual milling, resulting in low precision in milling. Utility Model Content

[0005] In order to improve the working efficiency of milling cutter edge grinding, this application provides a milling cutter edge grinding device.

[0006] This application provides a milling cutter edge grinding device, which adopts the following technical solution:

[0007] A milling cutter edge grinding device includes a frame, a mounting platform rotatably mounted on the frame, a fixing component mounted on the mounting platform, a milling cutter mounted on the mounting platform via the fixing component, a rotating component mounted on the frame for driving the mounting platform to rotate, a grinding table horizontally slidable on the frame in a direction close to or away from the mounting platform, a grinding wheel rotatably mounted on the grinding table, a moving component mounted on the frame for controlling the movement of the grinding table, and a driving component mounted on the grinding table for driving the grinding wheel to rotate.

[0008] By adopting the above technical solution, a mounting table is installed on the frame. After the milling cutter is mounted on the mounting table via a fixed component, a moving component drives the grinding table to move. The movement of the grinding table causes the grinding wheel to come into contact with the milling cutter. The drive component then starts to rotate the grinding wheel, which grinds the cutting edge of the milling cutter. Once one side of the milling cutter's cutting edge is ground, the mounting table is driven to rotate via a rotating component, which in turn rotates the milling cutter to grind the cutting edges on the other sides of the milling cutter. This completes the grinding work of the milling cutter's cutting edge, eliminating the need for frequent manual handling of the milling cutter for grinding and greatly improving the efficiency and accuracy of the grinding work.

[0009] Optionally, the fixing component includes:

[0010] A fixing collar is provided on the mounting platform. The bottom of the milling cutter passes through the fixing collar. Two threaded fixing holes are provided on the outer wall of the fixing collar.

[0011] A fixing screw is threaded onto a threaded fixing hole and abuts against the outer wall of the bottom of the milling cutter.

[0012] By adopting the above technical solution, a fixing collar is installed on the mounting table. After the milling cutter to be ground is placed inside the fixing collar, the fixing screw is turned to connect with the threaded fixing hole and pass through the threaded fixing hole to abut against the bottom of the milling cutter. This completes the fixing and installation of the milling cutter on the mounting table. The operation is convenient and simple, and the work efficiency is high.

[0013] Optionally, the outer wall of the fixing collar is provided with several positioning notches, the positions of which correspond to the positions of the milling cutter that need to be ground, and the grinding table is provided with a positioning rod. When the grinding table moves to the point where the grinding wheel contacts the milling cutter, the positioning rod extends into the positioning notch.

[0014] By adopting the above technical solution, a positioning notch is opened on the outer wall of the fixed collar, and a positioning rod is used to set the positioning notch. This allows the angle of rotation required during grinding to be controlled, making the grinding work of the milling cutter more precise and stable.

[0015] Optionally, a worktable is horizontally slidable on the frame, the movement direction of the worktable is perpendicular to the movement direction of the grinding table, the mounting table is rotatably mounted on the worktable, and the rotating assembly includes:

[0016] A rotating motor is mounted on a worktable;

[0017] A first rotating wheel and a second rotating wheel, wherein the first rotating wheel is mounted on the output shaft of the rotating motor, and the second rotating wheel is coaxially mounted on the worktable with the mounting platform;

[0018] A first transmission belt is fitted onto a first rotating wheel and a second rotating wheel.

[0019] By adopting the above technical solution, the rotating motor starts and drives the first rotating wheel to rotate, the first rotating wheel drives the first transmission belt to rotate, the first transmission belt drives the second rotating wheel to rotate, and the second rotating wheel drives the mounting platform to rotate, thereby realizing the rotation of the mounting platform by controlling the rotating motor.

[0020] Optionally, the frame is provided with a control component for controlling the position of the worktable on the frame, the control component including:

[0021] A control motor is mounted on the frame;

[0022] A control screw is rotatably mounted on the frame and connected to the output shaft of a control motor. The control screw is threadedly connected to the worktable.

[0023] By adopting the above technical solution, the control motor starts and drives the control screw to rotate, and the rotation of the control screw drives the worktable to move horizontally. Thus, by controlling the control motor, the horizontal position of the worktable can be adjusted, which facilitates the adjustment of the position of the milling cutter during grinding.

[0024] Optionally, the moving component includes:

[0025] A mobile motor, which is mounted on the frame;

[0026] A movable lead screw is rotatably mounted on the frame and connected to the output shaft of a movable motor. The movable lead screw is threadedly connected to the grinding table.

[0027] By adopting the above technical solution, the moving motor starts and drives the moving lead screw to rotate, the moving lead screw drives the grinding table to move, and the grinding table drives the grinding wheel to contact or disengage from the milling cutter. Thus, the grinding work of the grinding wheel on the milling cutter is realized by controlling the moving motor.

[0028] Optionally, an adjustment platform is rotatably mounted on the grinding table, the grinding wheel is rotatably mounted on the adjustment platform, and an adjustment component is provided on the grinding table. The adjustment component is used to adjust the rotational position of the adjustment platform, and the adjustment component includes:

[0030] An adjusting column is mounted on an adjusting platform, and the piston rod of the adjusting cylinder is rotatably connected to the adjusting column.

[0031] A stabilizing spring, one end of which is mounted on the grinding table, and the other end of which is connected to an adjusting cylinder.

[0032] By adopting the above technical solution, the adjustment cylinder is activated, driving the adjustment column to move. The movement of the adjustment column then drives the adjustment table to rotate. Thus, by controlling the adjustment cylinder, the rotation of the adjustment table can be achieved. This allows the grinding wheel to perform multi-angle grinding on the cutting edge of the milling cutter, greatly improving the applicability of the grinding wheel to milling cutters with different grinding requirements. The stability of the adjustment cylinder is ensured by incorporating a stabilizing spring.

[0033] Optionally, the driving component includes:

[0034] A drive motor is mounted on the adjustment platform;

[0035] A first drive wheel and a second drive wheel, wherein the first drive wheel is mounted on the output shaft of the drive motor and the second drive wheel is coaxially and rotatably mounted on the adjustment table with the grinding wheel;

[0036] The second transmission belt is fitted onto the first drive wheel and the second drive wheel.

[0037] By adopting the above technical solution, the drive motor starts and drives the first drive wheel to rotate, the rotation of the first drive wheel drives the second transmission belt to rotate, the rotation of the second transmission belt drives the second drive wheel to rotate, and the rotation of the second drive wheel drives the grinding wheel to rotate. Thus, the rotation of the grinding wheel is realized by controlling the drive motor.

[0038] In summary, this application includes at least one of the following beneficial technical effects:

[0039] 1. By installing a mounting table on the frame, the end mill is mounted on the mounting table via a fixed component. The moving component drives the grinding table to move. The movement of the grinding table causes the grinding wheel to come into contact with the end mill. The drive component then starts to rotate the grinding wheel, which grinds the cutting edge of the end mill. Once one side of the end mill's cutting edge is ground, the rotating component drives the mounting table to rotate, which in turn rotates the end mill to grind the cutting edges on the other sides of the end mill. This completes the grinding of the end mill's cutting edge without the need for frequent manual handling of the end mill, greatly improving the efficiency and accuracy of the grinding work.

[0040] 2. The moving motor starts and drives the moving lead screw to rotate. The rotation of the moving lead screw drives the grinding table to move. The movement of the grinding table causes the grinding wheel to contact or disengage from the milling cutter. Thus, the grinding wheel grinds the milling cutter by controlling the moving motor.

[0041] 3. The drive motor starts and drives the first drive wheel to rotate. The rotation of the first drive wheel drives the second transmission belt to rotate. The rotation of the second transmission belt drives the second drive wheel to rotate. The rotation of the second drive wheel drives the grinding wheel to rotate. Thus, the rotation of the grinding wheel is achieved by controlling the drive motor. Attached Figure Description
