Description

Technical Field

[0001] This utility model relates to the technical field of machining, and in particular to a grinding device for machining precision metal parts. Background Technology

[0002] A grinding device is used to grind workpieces, improving the smoothness of their surface. In the prior art, utility model patent application number 201720513433.6 discloses a high-efficiency metal grinding device, mainly composed of a motor, a grinding head, and a grinding base. When grinding a workpiece, the workpiece is fixed on the grinding base, and then the motor drives the grinding head to rotate, bringing the rotating grinding head into contact with the workpiece for grinding. However, this device has the following problems: to improve grinding efficiency, a coarse grinding head is first used for coarse grinding, followed by a fine grinding head for fine grinding. Therefore, the grinding device in the prior art requires manual replacement of the grinding head during the grinding process, which is inconvenient and reduces grinding efficiency. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a grinding device for precision metal parts processing that can not only rough grind but also fine grind workpieces, without the need to change the grinding head during the grinding process, thus improving grinding efficiency, and is convenient to use and highly practical.

[0004] This utility model discloses a grinding device for precision metal parts processing, comprising a base plate; it also includes a support plate, grinding machine A, grinding machine B, a coarse grinding wheel, a fine grinding wheel, a clamping mechanism, a lifting mechanism, and a moving mechanism. The support plate is mounted on the base plate via the moving mechanism, which is used to move the support plate left and right. Grinding machine A and grinding machine B are respectively mounted on the upper and lower parts of the support plate. Grinding machine A is equipped with a coarse grinding wheel, and grinding machine B is equipped with a fine grinding wheel. The clamping mechanism is mounted on the lifting mechanism and has the function of clamping and fixing. The lifting mechanism is used to raise and lower the clamping mechanism, which is located between the coarse grinding wheel and the fine grinding wheel. When grinding the outer wall of the workpiece, the workpiece is first clamped and fixed by the clamping mechanism. Then, the coarse grinding wheel is rotated by grinding machine A. Finally, the support plate is moved to the left by the moving mechanism, causing the support plate to move grinding machine A and the coarse grinding wheel. The process involves positioning the coarse grinding wheel above the workpiece, then using a lifting mechanism to move the workpiece along the clamping mechanism, causing it to rise. During this rise, the workpiece contacts the coarse grinding wheel, resulting in coarse grinding. Simultaneously, the clamping mechanism rotates the workpiece, allowing it to be evenly ground by the coarse grinding wheel. After coarse grinding, grinding machine B is activated, causing the fine grinding wheel to rotate at high speed. The lifting mechanism then lowers the workpiece, allowing it to contact the rotating fine grinding wheel for fine grinding. The workpiece is then evenly ground by the rotating fine grinding wheel. This system can perform both coarse and fine grinding without changing the grinding head, improving efficiency and offering ease of use and high practicality.

[0005] Preferably, the clamping mechanism includes a lifting block, a drive motor, a rotating shaft, and a three-jaw chuck. The lifting block is mounted on the lifting mechanism, which is used to adjust the height of the lifting block. The drive motor is fixedly mounted on the lifting block, and the rotating shaft is rotatably mounted on the lifting block. The left end of the rotating shaft is connected to the output end of the drive motor, and the three-jaw chuck is fixedly mounted on the right end of the rotating shaft. When clamping and fixing the workpiece, the left part of the workpiece is placed on the three-jaw chuck, and the left part of the workpiece is clamped and fixed by the three-jaw chuck. When the outer wall of the workpiece is polished by the coarse grinding wheel and the fine grinding wheel, the drive motor is turned on. The drive motor causes the three-jaw chuck to slowly rotate the workpiece through the rotating shaft. During the rotation, the workpiece can be uniformly polished circumferentially by the coarse grinding wheel or the fine grinding wheel.

[0006] Preferably, the lifting mechanism includes a fixed frame, a hydraulic cylinder, and a sliding rod. The fixed frame is fixedly mounted on the base plate, the hydraulic cylinder is fixedly mounted on the upper end of the fixed frame, and the sliding rod is slidably mounted on the upper part of the fixed frame. The upper end of the sliding rod is connected to the output end of the hydraulic cylinder, and the lifting block is fixedly mounted on the lower end of the sliding rod. When adjusting the height of the workpiece, the hydraulic cylinder is opened, and the hydraulic cylinder adjusts the height of the lifting block through the sliding rod. The lifting block then uses a rotating shaft to drive the three-jaw chuck to adjust the height of the workpiece. This facilitates the adjustment of the workpiece height.

[0007] Preferably, the moving mechanism includes an electric slide rail and a moving plate. The electric slide rail is fixedly installed on the base plate, and the moving plate is installed on the electric slide rail. The electric slide rail is used to move the moving plate left and right. A support plate is fixedly installed on the upper end of the moving plate. When the coarse grinding wheel and the fine grinding wheel move left and right, the electric slide rail is opened. The electric slide rail drives the moving plate to move left and right in the same direction. The moving plate drives the support plate to move left and right in the same direction. The support plate drives the grinding machine A and the grinding machine B to move. The grinding machine A and the grinding machine B then drive the coarse grinding wheel and the fine grinding wheel to move left and right in the same direction. This facilitates the movement of the coarse grinding wheel and the fine grinding wheel.

[0008] Preferably, the assembly also includes a hydraulic cylinder, a lifting rod, a lifting plate, and a polishing wax block. The hydraulic cylinder is fixedly mounted on the upper end of the movable plate, the lifting rod is mounted on the output end of the upper part of the hydraulic cylinder, the lifting plate is fixedly mounted on the upper end of the lifting rod, and the polishing wax block is fixedly mounted on the upper end of the lifting plate, with the polishing wax block located below the fine grinding wheel. When the workpiece is being polished by the fine grinding wheel, and when it is necessary to add polishing wax to improve the polishing effect, the hydraulic cylinder is opened. The hydraulic cylinder, through the lifting rod, causes the lifting plate to lift the polishing wax block, making the polishing wax block contact the rotating fine grinding wheel. The rotating fine grinding wheel applies some of the wax from the polishing wax block to the surface of the fine grinding wheel, after which the fine grinding wheel polishes the workpiece, improving the polishing quality and facilitating the addition of polishing wax.

[0009] Preferably, the support plate is provided with a clearance hole located on the right side of the workpiece; this arrangement avoids interference between the support plate and the workpiece during leftward movement, thus improving reliability.

[0010] Preferably, the hydraulic cylinder is equipped with a dust cover; this feature improves the cleanliness of the hydraulic cylinder during use.

[0011] Compared with the prior art, the advantages of this utility model are: it can not only rough grind the workpiece, but also fine grind the workpiece. There is no need to change the grinding head during the grinding process, which improves the grinding efficiency. It is convenient to use and highly practical. Attached Figure Description

This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example

[0019] like Figures 1 to 5The precision metal parts processing grinding device of this utility model includes a base plate 1, a support plate 2, a grinding machine A3, a grinding machine B4, a coarse grinding wheel 5, a fine grinding wheel 6, a clamping mechanism, a lifting mechanism, and a moving mechanism. The support plate 2 is mounted on the base plate 1 via the moving mechanism, which is used to move the support plate 2 left and right. The grinding machine A3 and the grinding machine B4 are respectively mounted on the upper and lower parts of the support plate 2. The coarse grinding wheel 5 is provided on the grinding machine A3, and the fine grinding wheel 6 is provided on the grinding machine B4. The clamping mechanism is mounted on the lifting mechanism and has the function of clamping and fixing. The lifting mechanism is used to raise and lower the clamping mechanism. The clamping mechanism is located between the coarse grinding wheel 5 and the fine grinding wheel 6. When grinding the outer wall of the workpiece 21, the workpiece 21 is first clamped and fixed by the clamping mechanism. Then, the coarse grinding wheel 5 is rotated by the grinding machine A3. Then, the support plate 2 is moved to the left by the moving mechanism, so that the support plate 2 drives the grinding machine A3 and the coarse grinding wheel 5 to move, so that the coarse grinding wheel 5 is positioned... The workpiece 21 is positioned above the clamping mechanism, which then moves the workpiece 21 upwards. During this upward movement, the workpiece 21 contacts the coarse grinding wheel 5, resulting in coarse grinding. Simultaneously, the clamping mechanism rotates the workpiece 21, allowing it to be evenly ground by the coarse grinding wheel 5. After the coarse grinding is complete, the grinding machine B4 is activated, causing the fine grinding wheel 6 to rotate at high speed. The lifting mechanism then lowers the workpiece 21, allowing it to contact the rotating fine grinding wheel 6 for fine grinding. The workpiece 21 is then evenly ground by the fine grinding wheel 6 during this descent. This method not only performs coarse grinding but also fine grinding on the workpiece 21. The grinding head does not need to be changed during the grinding process, improving efficiency and making it convenient and practical.

[0020] like Figure 1 and Figure 5 The clamping mechanism includes a lifting block 7, a drive motor 8, a rotating shaft 9, and a three-jaw chuck 10. The lifting block 7 is mounted on the lifting mechanism, which is used to adjust the height of the lifting block 7. The drive motor 8 is fixedly mounted on the lifting block 7, and the rotating shaft 9 is rotatably mounted on the lifting block 7. The left end of the rotating shaft 9 is connected to the output end of the drive motor 8, and the three-jaw chuck 10 is fixedly mounted on the right end of the rotating shaft 9. When clamping and fixing the workpiece 21, the left part of the workpiece 21 is placed on the three-jaw chuck 10, and the left part of the workpiece 21 is clamped and fixed by the three-jaw chuck 10. When the outer wall of the workpiece 21 is polished by the coarse grinding wheel 5 and the fine grinding wheel 6, the drive motor 8 is turned on. The drive motor 8 drives the three-jaw chuck 10 to slowly rotate the workpiece 21 through the rotating shaft 9. During the rotation, the workpiece 21 can be polished evenly around the circumference by the coarse grinding wheel 5 or the fine grinding wheel 6.

[0021] like Figure 1 and Figure 5 The lifting mechanism includes a fixed frame 11, a hydraulic cylinder 12, and a sliding rod 13. The fixed frame 11 is fixedly installed on the base plate 1, the hydraulic cylinder 12 is fixedly installed on the upper end of the fixed frame 11, and the sliding rod 13 is slidably installed on the upper part of the fixed frame 11. The upper end of the sliding rod 13 is connected to the output end of the hydraulic cylinder 12, and the lifting block 7 is fixedly installed on the lower end of the sliding rod 13. When adjusting the height of the workpiece 21, the hydraulic cylinder 12 is opened, and the hydraulic cylinder 12 adjusts the height of the lifting block 7 through the sliding rod 13. The lifting block 7 adjusts the height of the workpiece 21 by rotating the shaft 9 and causing the three-jaw chuck 10 to move the workpiece 21. This facilitates the adjustment of the height of the workpiece 21.

[0022] like Figure 1 and Figure 3 The moving mechanism includes an electric slide rail 14 and a moving plate 15. The electric slide rail 14 is fixedly installed on the base plate 1, and the moving plate 15 is installed on the electric slide rail 14. The electric slide rail 14 is used to move the moving plate 15 left and right. The support plate 2 is fixedly installed on the upper end of the moving plate 15. When the coarse grinding wheel 5 and the fine grinding wheel 6 move in the left and right direction, the electric slide rail 14 is opened. The electric slide rail 14 drives the moving plate 15 to move in the left and right direction. The moving plate 15 drives the support plate 2 to move in the left and right direction. The support plate 2 drives the grinding machine A3 and the grinding machine B4 to move. The grinding machine A3 and the grinding machine B4 drive the coarse grinding wheel 5 and the fine grinding wheel 6 to move in the left and right direction. This facilitates the movement of the coarse grinding wheel 5 and the fine grinding wheel 6.

[0023] like Figure 3 and Figure 4 It also includes a hydraulic cylinder 16, a lifting rod 17, a lifting plate 18, and a polishing wax block 19.

When the workpiece 21 is polished by the fine grinding wheel 6, and when it is necessary to add polishing wax to improve the polishing effect, the hydraulic cylinder 16 is opened. The hydraulic cylinder 16 causes the lifting plate 18 to lift the polishing wax block 19 through the lifting rod 17, so that the polishing wax block 19 contacts the rotating fine grinding wheel 6. The rotating fine grinding wheel 6 attaches some of the wax on the polishing wax block 19 to the surface of the fine grinding wheel 6. Then the fine grinding wheel 6 polishes the workpiece 21, which improves the polishing quality and facilitates the addition of polishing wax.

[0024] like Figure 3 The support plate 2 is provided with a clearance hole 20, which is located on the right side of the workpiece 21. This arrangement avoids interference between the support plate 2 and the workpiece 21 during the leftward movement, thus improving reliability. Example
