[0026] As Figures 1-4As shown in the figure, an embodiment of the utility model provides a clamping device for solenoid valve production, including: an L-shaped plate 1, a vertical clamping mechanism 3 is arranged on the lower surface of the inner wall of the L-shaped plate 1, and a horizontal fixing mechanism 2 is arranged below the vertical clamping mechanism 3. The vertical clamping mechanism 3 includes a telescopic cylinder 30 and a fixing plate 31. One side of the fixing plate 31 is fixedly connected to the inner wall of the L-shaped plate 1. The telescopic end of the telescopic cylinder 30 movably penetrates through the upper and lower ends of the fixing plate 31 and is fixedly connected to a moving round table 34. Three groups of cylinders 32 are fixedly connected to the lower end of the fixing plate 31. The lower ends of the three groups of cylinders 32 all movably penetrate through the round table 34 and are fixedly connected to mounting parts 33. A central rod 39 movably penetrates through the middle of the mounting part 33. A limiting sliding groove 310 is opened at the lower end of the central rod 39.

One group of clamping parts 36 is rotatably connected to the lower ends of each two groups of rotating connecting rods 35. Rubber cushion blocks 37 are fixedly connected to the lower ends of the three groups of clamping parts 36. The middle parts of the three groups of rotating connecting rods 35 close to the mounting part 33 are respectively rotatably connected to the three groups of limiting connecting rods 38. The upper end of the telescopic cylinder 30 is fixed to the lower end of the inner wall of the L-shaped plate 1. The solenoid valve workpiece is placed between two positioning concave blocks 24. When the three groups of rubber cushion blocks 37 clamp the solenoid valve workpiece, the upper end screw of the solenoid valve workpiece is located in the positioning groove 314. The telescopic cylinder 30 is started. The telescopic end of the telescopic cylinder 30 shortens to drive the round table 34 to slide upward along the cylinder 32, further driving the lower ends of the six groups of rotating connecting rods 35 to rotate in the direction close to the rubber round block 313 with the connecting position with the special-shaped part as the axis, further driving the limiting connecting rods 38 to rotate in the direction close to the rubber round block 313 at the same time, playing a role in supporting the rotating connecting rods 35, and then making the clamping parts 36 and the rubber cushion blocks 37 close to the solenoid valve workpiece to clamp the upper cylinder 32 part of the solenoid valve workpiece. By pushing the rubber round block 313, the rubber round block 313 is made to push the limiting sliding rod 311 to slide upward along the limiting sliding groove 310 of the central rod 39, further making the lower end of the second spring 312 be cooperatively extruded by the mounting part 33 and the rubber round block 313 to generate a compressive deformation. When the solenoid valve workpiece is placed, the positioning groove 314 is clamped with the upper end screw of the solenoid valve workpiece to achieve a positioning effect, and the second spring 312 restores the compressive deformation to drive the rubber round block 313 to move downward to press the solenoid valve workpiece. After completing the horizontal upward fixation, the vertical positioning is further strengthened to improve the production and processing accuracy of the solenoid valve.

[0027] AsFigures 1-4 As shown, the horizontal fixing mechanism 2 includes a concave plate 20. One side of the concave plate 20 is fixedly connected to the lower end of the L-shaped plate 1. Limiting rings 25 are fixedly connected to both sides of the outer wall of the concave plate 20. Pull rods 22 are slidably connected to the inner walls of the two groups of limiting rings 25.

One ends of the two groups of pull rods 22 are fixedly connected with positioning concave blocks 24. The other ends of the two groups of pull rods 22 are fixedly connected with handles 21. First springs 23 are arranged on the outer side walls of the two groups of pull rods 22. One end of the first spring 23 is fixed to the positioning concave block 24, and the other end of the first spring 23 is fixed to one side of the inner wall of the concave plate 20. Circular chamfers are arranged at the turning positions of the inner walls of the two groups of positioning concave blocks 24. Circular chamfers are arranged at the lower edge position of the rubber round block 313. The frustum 34 and the central rod 39 are concentrically arranged. The limiting ring 25 and the pull rod 22 are concentrically arranged. By pulling the handle 21, the handle 21 drives the pull rod 22 to move along the inner wall of the limiting ring 25 in a direction away from the concave plate 20. Further, when the positioning concave plate approaches the inner wall of the concave plate 20, both ends of the first spring 23 are squeezed to generate compressive deformation. Place the solenoid valve workpiece to be processed between the two groups of positioning concave blocks 24, and then release the handle 21 to make the first spring 23 extend and recover the compressive deformation. Further, the two groups of positioning concave blocks 24 approach each other and cooperate to clamp the solenoid valve workpiece.

[0028] For the technical solution provided by the present utility model, first, by pulling the handle 21, the handle 21 drives the pull rod 22 to move along the inner wall of the limit ring 25 in a direction away from the concave plate 20. Further, during the process of the positioning concave plate approaching the inner wall of the concave plate 20, both ends of the first spring 23 are squeezed to generate a compressive deformation. Place the solenoid valve workpiece to be processed between the two groups of positioning concave blocks 24, and then release the handle 21 to enable the first spring 23 to elongate and recover the compressive deformation. Further, the two groups of positioning concave blocks 24 approach each other and cooperate to clamp the solenoid valve workpiece. Subsequently, by starting the telescopic cylinder 30, the telescopic end of the telescopic cylinder 30 shortens to drive the frustum 34 to slide upward along the cylinder 32. Further, it drives the lower ends of the six rotating link rods 35 to rotate in a direction approaching the rubber round block 313 with the connection position with the special-shaped part as the axis. Further, it drives the limit link rod 38 to rotate in a direction approaching the rubber round block 313 at the same time, playing a role in supporting the rotating link rod 35. Then, the clamping member 36 and the rubber cushion block 37 approach the solenoid valve workpiece to clamp the upper cylinder 32 part of the solenoid valve workpiece. By pushing the rubber round block 313, the rubber round block 313 pushes the limit slide rod 311 to slide upward along the limit slide groove 310 of the central rod 39. Further, the lower end of the second spring 312 is cooperatively squeezed by the mounting member 33 and the rubber round block 313 to generate a compressive deformation. When the solenoid valve workpiece is placed, the positioning groove 314 is clamped with the upper-end screw of the solenoid valve workpiece to achieve a positioning effect, and the second spring 312 recovers the compressive deformation to drive the rubber round block 313 to move downward to press the solenoid valve workpiece. After completing the fixation in the horizontal upward direction, the positioning in the vertical direction is further strengthened to improve the production and processing accuracy of the solenoid valve.
