The embodiments of this utility model will be described below based on its overall structure.

[0027] Please see Figures 1-5 A metalworking grinding device with a positioning structure includes a processing table 1.

[0028] A rotatable rotating disk 2 is installed at the top center of the processing table 1, and multiple mounting seats 3 for clamping workpieces are installed at equal angles on the outer side of the top of the rotating disk 2.

[0029] A fixed seat 4 is provided on one side of the top of the processing table 1, and a lifting and lowering grinding mechanism 5 is installed on the fixed seat 4;

[0030] A protective arc plate 6 is provided on the side of the top of the processing table 1 away from the fixed seat 4. The inner arc surface of the protective arc plate 6 faces the rotating disk 2, and its two ends extend to the outside of the grinding area of ​​the grinding mechanism 5.

[0031] like Figures 1-5 As shown, the top of the mounting base 3 has a groove 7, and a bidirectional screw 8 is rotatably connected in the groove 7. The outer walls of both ends of the bidirectional screw 8 are symmetrically threaded with threaded plates 9. The top of the threaded plates 9 is provided with an adjustable clamping plate. One end of the bidirectional screw 8 passes through the mounting base 3 and is connected to a handle 10. By rotating the handle 10, the bidirectional screw 8 can be rotated, controlling the two sets of fixing plates 11 to move towards or away from each other. At this time, the metal parts placed on the top of the mounting base 3 will be clamped and fixed by the clamping plates, which is convenient for subsequent grinding work.

[0032] like Figures 1-5As shown, the clamping plate includes a fixing plate 11 fixed to the top of the threaded plate 9. At least two horizontally arranged threaded rods 12 are threadedly connected to the fixing plate 11. The ends of the threaded rods 12 are rotatably connected to elastic arc-shaped clamping plates 13. During the process of the two sets of clamping plates moving towards each other, the elastic arc-shaped clamping plates 13 will first adhere to the outer wall of the metal workpiece. At this time, by rotating the threaded rods 12, the shape of the elastic arc-shaped clamping plates 13 can be adjusted to increase the contact area with the metal workpiece, so as to adapt to metal workpieces of different specifications. Then, by rotating the handle 10, the elastic arc-shaped clamping plates 13 apply clamping force to the metal workpiece, so that the metal workpiece is fixed. When one set of metal workpieces is being ground under the grinding mechanism 5, other components to be ground can be installed and fixed on the top of the mounting seats 3 of the other sets, improving work efficiency. After the metal workpieces are ground, the next set of metal workpieces can be moved to the bottom of the grinding mechanism 5 by rotating the rotating disk 2. The metal workpieces can be disassembled or installed at the same time as grinding.

[0033] like Figures 1-5 As shown, the grinding mechanism 5 includes an L-shaped bracket 501 fixed to the top of the fixed base 4. A vertically arranged threaded rod 502 is rotatably connected to the inner side of the vertical section of the L-shaped bracket 501. A drive motor 503 is connected to the bottom of the threaded rod 502. A Z-shaped slider 504 is threadedly connected to the threaded rod 502. A drive motor 505 is installed at the bottom of the Z-shaped slider 504. The output shaft of the drive motor 505 passes through the fixed base 4 and is connected to the grinding disc 506. After the metal workpiece is clamped and fixed, the drive motor 505 is started to make the grinding disc 506 start to rotate. At this time, the drive motor 503 is started to control the threaded rod 502 to rotate, which will drive the Z-shaped slider 504 to move downward, so that the grinding disc 506 is close to the metal workpiece for grinding. By controlling the up and down position of the Z-shaped slider 504, metal workpieces of different heights can be ground. The through hole opened at the top of the fixed base 4 can accommodate the drive motor 505 to pass through.

[0034] like Figures 1-5 As shown, the front and rear ends of the protective arc plate 6 are provided with arc-shaped slots, and an arc-shaped baffle 14 is movably installed inside the arc-shaped slot. During the grinding of metal workpieces, the arc-shaped baffle 14 is pulled out and forms a circular structure with the fixed seat 4 to prevent debris from flying during grinding and facilitate subsequent collection and cleaning.

[0035] like Figures 1-5 As shown, the front and rear ends of the fixing base 4 are provided with engagement grooves 15 that engage with the arc-shaped baffle 14. The engagement grooves 15 can engage and fix the arc-shaped baffle 14.

[0036] Working principle: During use, rotating the handle 10 rotates the bidirectional screw 8, controlling the two sets of fixing plates 11 to move towards or away from each other. This clamps the metal parts placed on top of the mounting base 3, facilitating subsequent grinding. During the relative movement of the two sets of clamping plates, the elastic arc-shaped clamping plate 13 first adheres to the outer wall of the metal workpiece. Rotating the threaded rod 12 adjusts the shape of the elastic arc-shaped clamping plate 13, increasing the contact area with the metal workpiece to accommodate different sizes. Then, rotating the handle 10 applies clamping force to the elastic arc-shaped clamping plate 13, fixing the metal workpiece in place. While one set of metal workpieces is being ground under the grinding mechanism 5, other components to be ground can be mounted and fixed on the tops of the other sets of mounting bases 3, improving work efficiency. After the metal workpiece is polished, the next set of metal workpieces can be moved to the bottom of the polishing mechanism 5 by rotating the rotating disk 2. The metal workpiece can be disassembled or installed at the same time as polishing. After the metal workpiece is clamped and fixed, the second drive motor 505 is started to make the polishing disk 506 start to rotate. At this time, the first drive motor 503 is started to control the second threaded rod 502 to rotate, which will drive the Z-shaped slider 504 to move downward, so that the polishing disk 506 is close to the metal workpiece for polishing. By controlling the up and down position of the Z-shaped slider 504, metal workpieces of different heights can be polished. The through hole opened at the top of the fixed seat 4 can accommodate the second drive motor 505 to pass through. During the polishing of the metal workpiece, the arc baffle 14 is pulled out to form a circular structure with the fixed seat 4 to avoid the flying of debris during polishing and facilitate subsequent collection and cleaning.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
