Description

Technical Field

[0001] The utility model provides a stable milling cutter grinding device, belonging to the technical field of milling cutter grinding devices. Background Technique

[0002] A milling cutter is a multi-edge rotary cutter used for milling workpieces on a milling machine. It is widely used in the machinery manufacturing industry for milling various complex geometric shapes such as planes, grooves, steps, holes, and formed surfaces. During the milling process, due to the strong friction and impact with the workpiece material, the cutting edge of the milling cutter will gradually wear, resulting in a dull cutting edge, increased roughness, and increased cutting force. This will not only reduce the machining accuracy and surface quality but may also cause workpiece deformation and premature tool failure. For clamped cutters, only the inserts need to be replaced, while for integral milling cutters, grinding is required to reshape the cutting edge of the milling cutter to make it sharp again, ensuring the cutting edge strength and sharpness during cutting, thereby improving the cutting efficiency and extending the tool life.

[0003] Currently, milling cutters are all ground by workers holding them by hand. Since the handles of milling cutters are cylindrical, when the milling cutter touches the grinding wheel, it will shake and is not stable. Moreover, when grinding a flat milling cutter, the end face of the milling cutter needs to be as flat as possible, which is difficult for workers to control. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is that currently, when workers grind milling cutters, they will shake, and when grinding flat milling cutters, the end face of the milling cutter is not flat enough.

The cylinder shafts of the cylinders are connected to the side walls of the connecting frames without auxiliary rods;

[0010] As an improvement, when the cylinder shafts of the cylinders are at their longest, the end of the sleeve close to the cylinder exceeds the end of the grinding disc of the grinding machine away from the cylinder.

Specific Embodiments

[0018] The following further describes the present utility model in conjunction with the accompanying drawings.

[0019] According to Figure 1 —4 shows: The present utility model provides a stable milling cutter grinding device, including a grinding machine 1, a frame 3, and a milling cutter. The grinding machine 1 is arranged on the upper part of the frame 3 through a hydraulic rod 2. A fixing mechanism 4 capable of driving the milling cutter to rotate is provided in the middle and lower parts of the frame 3. The fixing mechanism 4 is controlled by two cylinders 5 arranged outside the frame 3 to move back and forth, left and right within the frame 3. By providing a fixing mechanism 4 capable of driving the milling cutter to rotate, by providing two cylinders 5 to control the fixing mechanism 4 to move back and forth, left and right within the frame 3, and in cooperation with the grinding machine 1, the milling cutter can rotate and move during grinding, so that the end face of the milling cutter can be ground flat by the grinding disc rotating with the grinding machine.

[0020] According to Figure 1 、 2 、4 shows: The frame 3 includes a top plate 301. Four corners below the top plate 301 are provided with support rods 302. The lower parts of the four support rods 302 are provided with side plates 303 distributed in a rectangle. Rectangular holes 304 are provided on the side plates 303. Fixing holes 305 are provided above and below any two rectangular holes 304 arranged at 90°. An L-shaped plate one 306 with a downward opening is provided above the fixing hole 305 at the upper part, and an L-shaped plate two 307 with an upward opening is provided below the fixing hole 305 at the lower part. A fixing plate 101 is provided outside the grinding machine 1. A connecting platform 102 is provided on one side of the fixing plate 101. The lower end of the hydraulic rod 2 is connected to the connecting platform 102, and the upper end is connected to the top plate 301. In this way, by changing the length of the hydraulic rod 2, the height of the grinding machine 1 can be changed, so that the grinding machine 1 can grind the milling cutter.

[0021] According to Figure 1 、 2 shows: The fixing mechanism 4 includes a sleeve 401. Threaded rods 402 passing through the side wall of the sleeve 401 and threadedly connected to the side wall of the sleeve 401 are respectively provided at the upper and lower parts of the sleeve 401. A motor 403 is provided at the lower end of the sleeve 401. A connecting frame 404 is provided outside the motor 403. Auxiliary rods 405 passing through the rectangular holes 304 are respectively provided on the side walls of any two connecting frames 404 arranged at 90°. In this way, after the milling cutter is placed into the sleeve 401 with the cutting edge facing upward, by rotating the threaded rod 402, one side of the milling cutter can be fitted to the inner wall of the sleeve 401, so that the milling cutter is vertically fixed.

[0022] According to Figure 1 、 2, as shown in Figure 4: Two cylinders 5 are respectively slidably arranged in the middle parts of two L-shaped plates 306 and 307 on the same side that are distributed at 90°, and are fixed by fixing pins 501 inserted into the upper and lower fixing holes 305 on both sides of the cylinder 5. The cylinder shaft of the cylinder 5 is connected to the side wall of the connection frame 404 without the auxiliary rod 405. When the cylinder shaft of the cylinder 5 is at its longest, the end of the sleeve 401 close to the cylinder 5 exceeds the end of the grinding disc of the grinding machine 1 far from the cylinder 5. When the cylinder shaft of the cylinder 5 is at its shortest, the end of the sleeve 401 far from the cylinder 5 exceeds the end of the grinding disc of the grinding machine 1 close to the cylinder 5. In this way, after fixing one side of the cylinder 5, starting the cylinder 5 can drive the fixing mechanism 4 and the other cylinder 5 to move, so as to realize that the milling cutter contacts the grinding discs of the grinding machine 1 at different positions, and further make the end face of the milling cutter flat during grinding.

[0023] Principle of the present utility model: During use, first place the milling cutter with its cutting edge facing up into the sleeve 401, and then rotate the screw rod 402 to make one side of the milling cutter fit the inner wall of the sleeve 401, so that the milling cutter is vertically fixed. Then insert the fixing pins 501 into the upper and lower fixing holes 305 on both sides of one side of the cylinder 5 respectively and start the grinding machine 1 and extend the hydraulic rod 2. The extension of the hydraulic rod 2 makes the grinding disc of the grinding machine 1 contact the upper end face of the milling cutter, and thus the end face of the milling cutter starts to be ground. Then start the motor 403 and the cylinder 5. The motor 403 will drive the milling cutter to rotate, and the extension of the cylinder shaft of the cylinder 5 will make the milling cutter and the unfixed cylinder 5 move towards one side. When the milling cutter moves out of the position of the grinding disc of the grinding machine 1, change the fixed and moving states of the two cylinders 5, and then make the milling cutter move from below the grinding disc of the grinding machine 1 along the other direction. In this way, when the milling cutter moves, it rotates in cooperation with the rotation of the grinding disc of the grinding machine 1, making the end face of the milling cutter flat during grinding.

[0024] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the creation of the present utility model, design similar structural manners and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present utility model.
