[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The positioning device for processing metal valve stems involves placing the metal valve stem between the corresponding triangular slots of the placement plate and the clamping plate, rotating the threaded rod, which is simultaneously threaded to the placement plate and the clamping plate. As the threaded rod rotates, the clamping plate gradually moves closer to the placement plate, causing the triangular slots to clamp the metal valve stem for positioning.

[0014] 2. The positioning device for machining the metal valve stem drives the lead screw to rotate through the output shaft of the first motor. When the lead screw rotates, the slider connected to it by threads slides in the groove along the axial direction of the lead screw. Since one of the connecting frames is fixed at the top of the slider, the sliding of the slider drives the connecting frame to move, thereby adjusting the distance between the two connecting frames to accommodate metal valve stems of different lengths.

[0015] 3. The positioning device for machining metal valve stems reduces wear on the valve stem surface by using a wear-resistant pad on the inner wall of the triangular groove of the placement plate. Multiple ball bearings on the inner wall of the wear-resistant pad make the placement and removal of the valve stem smoother, and facilitate subsequent rotation and adjustment of the metal valve stem. The anti-slip rubber pad on the inner wall of the triangular groove of the clamping plate increases the friction between the valve stem and the valve stem, preventing the valve stem from sliding during machining. The inclined surface inside the triangular groove allows for stable clamping of metal valve stems of different diameters.

[0016] 4. The positioning device for processing metal valve stems can drive the movable frame and drive rollers to move downwards through the extension of the piston rod of the cylinder, so that the metal valve stem to be processed is clamped in the gap between the two support rollers and the two drive rollers. Then, the output shaft of the second motor can rotate to drive the drive rollers to rotate, thereby driving the metal valve stem to rotate, so that the metal valve stem can be rotated, which facilitates the processing of different surfaces.

DETAILED DESCRIPTION

[0023] Summarized above: through support frame 1 and processing table 2 constitute basic support structure, processing table 2 is fixed on the upper surface of support frame 1, two connecting frames 3 are located above processing table 2 respectively, one of connecting frames 3 is fixed on the upper surface of processing table 2, the other connecting frame 3 is fixed on the top of sliding block 7, sliding block 7 can slide in the sliding slot in the inner wall of processing table 2, placing plate 4 is fixed on the top of connecting frame 3, clamping plate 5 is connected with placing plate 4 through threaded rotating rod 9, for positioning metal valve rod.

[0024] The first motor 8 is started, and its output shaft drives the lead screw 6 to rotate. As the lead screw 6 rotates, the slider 7, which is threadedly connected to it, slides within the groove along the axial direction of the lead screw 6. Since another connecting bracket 3 is fixed to the top of the slider 7, the sliding of the slider 7 causes the connecting bracket 3 to move, thereby adjusting the distance between the two connecting brackets 3 to accommodate metal valve stems of different lengths. The metal valve stem is placed between the corresponding triangular slots of the placement plate 4 and the clamping plate 5. The threaded rotating rod 9 is rotated, and it simultaneously connects threadedly to the placement plate 4 and the clamping plate 5. As the plate rotates, the clamping plate 5 gradually approaches the placement plate 4, causing the triangular slot to clamp the metal valve stem. The wear-resistant pad 10 on the inner wall of the triangular slot of the placement plate 4 reduces wear on the valve stem surface. The multiple balls 12 on the inner wall of the wear-resistant pad 10 make the placement and removal of the valve stem smoother, and also facilitate subsequent rotational adjustment of the metal valve stem. The anti-slip rubber pad 11 on the inner wall of the triangular slot of the clamping plate 5 increases the friction between the valve stem and the valve stem, preventing the valve stem from sliding during processing. The interior of the triangular slot is set with an inclined surface, which can stably clamp metal valve stems of different diameters.

[0025] To adjust the rotation of the metal valve stem, such as Figures 1-4 As shown, a fixed plate 13 is fixedly connected to the upper surface of the processing table 2, a connecting plate 14 is fixedly connected to the side wall of the fixed plate 13, a cylinder 15 is fixedly connected to the upper surface of the connecting plate 14, a movable frame 16 is fixedly connected to the piston rod end of the cylinder 15, two drive rollers 17 are rotatably connected inside the movable frame 16, a second motor 18 is fixedly connected to the side wall of the movable frame 16, the second motor 18 is fixedly connected to one of the drive rollers 17, a rectangular opening is opened on the inner wall of the fixed plate 13, the second motor 18 is slidably disposed on the inner wall of the fixed plate 13 located at the rectangular opening, two support rollers 19 are rotatably connected to the bottom inner wall of the fixed plate 13, and the outer sides of the two support rollers 19 are aligned with the inner wall of the wear-resistant pad 10.

[0026] When the metal valve stem needs to be rotated and adjusted, the piston rod of the cylinder 15 extends and drives the movable frame 16 and the drive roller 17 to move down, so that the metal valve stem being processed is clamped in the gap between the two support rollers 19 and the two drive rollers 17. Then, the output shaft of the second motor 18 rotates and drives the drive roller 17 to rotate, thereby driving the metal valve stem to rotate, which facilitates the processing of different surfaces.
