Example

[0037] according to Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 and Figure 7As shown, the turntable mechanism 3 includes a No. 1 annular slide rail 31, which is fixedly connected to the upper part of the processing table 16, and an annular slider 32 is rotatably connected inside the No. 1 annular slide rail 31, and the upper part of the annular slider 32 is fixedly connected to the turntable body 33, and the upper part of the turntable body 33 is fixedly connected to the No. 2 annular slide rail 34, and the No. 2 annular slide rail 34 is slidably connected to the arc slider 35. The upper part is fixedly connected to the connecting frame 37, and the surface of the connecting frame 37 is threadedly connected to the limiting threaded rod 38, and one end of the limiting threaded rod 38 is rotatably connected to the splint 39, and the bottom of the splint 39 is fixedly connected to the anti-slip rubber pad 310, and the surface of the No. 2 annular slide rail 34 is threadedly connected to the pin 36, which passes through the surface of the No. 2 annular slide rail 34 and is threadedly connected to the arc slider 35. The surface of the No. 2 annular slide rail 34 is provided with a plurality of limiting holes, and the plurality of limiting holes are evenly distributed on the surface of the No. 2 annular slide rail 34. The pin 36 is located inside the limiting hole and is threadedly connected to the No. 2 annular slide rail 34.

[0038] The workpiece to be processed is placed on the surface of the turntable body 33, and the clamping plate 39 is pushed to clamp the workpiece to the surface of the turntable body 33 by rotating the limiting threaded rod 38. The anti-slip rubber pad 310 is tightly squeezed against the surface of the workpiece to increase the friction force at the workpiece fixing point, thereby improving the stability of the workpiece fixing. Before fixing the workpiece, according to the shape of the workpiece, the arc-shaped slider 35 is slid along the second annular slide rail 34 to adjust the position of the clamping plate 39 so that it is located above the workpiece fixing point. At the same time, the pin 36 is threadedly connected to the second annular slide rail 34 and the arc-shaped slider 35 to fix the position of the clamping plate 39. The position of the clamping plate 39 can be adjusted to facilitate clamping and fixing workpieces of different shapes.

[0039] During the processing of the fixed workpiece on the surface of the turntable body 33, when the position of the workpiece needs to be adjusted, the reduction motor 21 is turned on to drive the No. 2 transmission inner tube 213 to rotate, thereby driving the No. 2 transmission outer tube 212 and the transmission shaft 26 on it to rotate. Under the rotation action of the transmission shaft 26, the turntable body 33 is driven to rotate, thereby driving the workpiece on the upper part of the turntable body 33 to rotate, which is convenient for processing operations on multiple positions of the workpiece.

[0040] The method of use and working principle of this device are as follows: the workpiece to be processed is placed on the surface of the turntable body 33, and the workpiece is clamped and fixed on the surface of the turntable body 33 by rotating the limiting threaded rod 38 to push the clamping plate 39. Before fixing the workpiece, according to the shape of the workpiece, the arc-shaped slider 35 is slid along the second annular slide rail 34, and the position of the clamping plate 39 is adjusted so that it is located above the workpiece fixing position. At the same time, the pin 36 is threadedly connected with the second annular slide rail 34 and the arc-shaped slider 35 to fix the position of the clamping plate 39.

[0041] During the machining process of a workpiece fixed on the surface of the turntable body 33, if the position of the workpiece needs to be adjusted, the reduction motor 21 is turned on to drive the second transmission inner tube 213 to rotate, thereby driving the second transmission outer tube 212 and the transmission shaft 26 on it to rotate, and the rotation of the transmission shaft 26 drives the turntable body 33 to rotate;

[0042] When the device needs to be moved, the fixing bolts on the surface of the strip limit slide 12 are removed, and then the No. 1 wedge limit plate 27 is manually rotated to be located below the No. 2 wedge limit plate 211, and the No. 1 wedge limit plate 27 is pushed upward. At this time, the telescopic rod 24 and the No. 1 spring 25 are compressed, and the No. 1 wedge limit plate 27 will push the No. 2 wedge limit plate 211 to move to both sides. At the same time, the No. 2 spring 210 is compressed. When the No. 1 wedge limit plate 27 reaches the upper part of the No. 2 wedge limit plate 211, the No. 2 spring 210 restores its deformation and pushes the second wedge-shaped limiting plate 211 to reset, supporting and limiting the first wedge-shaped limiting plate 27. When the first wedge-shaped limiting plate 27 drives the first transmission inner tube 23 to move upward, the second transmission outer tube 212 is separated from the upper part of the second transmission inner tube 213. Finally, the support plate 14 and the strip-shaped limiting slider 13 are pulled out from the lower part of the reinforcement plate 15. At this time, the processing table 16 and the lower base 11 are separated from each other. The processing table 16 and the structure above it are moved, and then the base 11 and the connected structure are moved.

[0043] After moving the device to the use position, the bar limit slider 13 is plugged into the bar limit slide rail 12, and then the bar limit slide rail 12 and the bar limit slider 13 are fixed with the fixing bolts, and then the No. 2 transmission inner tube 213 is rotated to align it with the limiting groove of the upper No. 2 transmission outer tube 212. At this time, the No. 2 connecting plate 214 is pulled. When the No. 2 wedge-shaped limiting plate 211 is disengaged from the bottom of the No. 1 wedge-shaped limiting plate 27, the telescopic rod 24 and the No. 1 spring 25 restore their deformation, pushing the No. 2 transmission outer tube 212 downward to plug it into the No. 2 transmission inner tube 213.
