The fixed clamping plate 2 is symmetrically and obliquely welded to the upper surface of one side of the base plate 1 along the length of the plate. A guide groove 3 for engaging a guide plate 4 is formed on the surface of the base plate 1 on one side of the fixed clamping plate 2. A movable clamping plate 6, obliquely inclined towards the fixed clamping plate 2, is welded to the upper plate of the guide plate 4 above the connecting plate 5. A tail plate 7 is welded to the back surface of the movable clamping plate 6 away from the upper connecting plate 5. Bolts are screwed between the outer surface of the tail plate 7 and the head plate 8, and an electric actuator 9 is welded to the center of the other plate surface of the head plate 8 away from the tail plate 7. The seat of the electric actuator 9 is bolted to the vertical plate of the L-shaped support plate 10, and the L-shaped support plate 10 is welded to the outside of the base plate 1 on one side of the moving clamp plate 6. The surface of the guide plate 4 is provided with a recessed hole 11, and a block 12 welded to the lower surface of the ramp block 13 is inserted into the recessed hole 11. Perforated plates 16 are symmetrically welded to the outer surface of the wide side plates at both ends of the base plate 1.

[0025] Among them, the guide groove 3 has a guide groove 14 opened at the opposite groove wall, and the guide strips 15 welded on both sides of the guide plate 4 are inserted into the guide groove 14.

[0026] By adopting the above technical solution, the guide groove 3 guides the guide bar 15 of the guide plate 4 with the guide groove 14, so that the guide bar 4 can slide stably in the guide groove 3.

[0027] Among them, a diagonal support rod is welded between the side of the tail plate 7 away from the head plate 8 and the moving clamp plate 6;

[0028] By adopting the above technical solution, a diagonal support rod is welded between the tail plate 7 and the moving clamp 6 to ensure the connection between the tail plate 7 and the moving clamp 6.

[0029] The ramp 13 is inclined and lowered on the surface of the guide plate 4 toward the fixed clamping plate 2, and the insert 12 below the ramp 13 is interference-fitted with the insert hole 11.

[0030] By adopting the above technical solution, the slope block 13 can be firmly locked in the hole 11 of the guide plate 4 with the help of the insert block 12.

[0031] Among them, the plate body of the guide plate 4 after the slope block 13 is clamped and the moving clamping plate 6 form a V-shaped clamping cavity;

[0032] By adopting the above technical solution, the V-shaped clamping cavity formed between the plate body of the guide plate 4 after the slope block 13 is clamped and the moving clamping plate 6 can be used to push the cylindrical valve body of the regulating valve toward the fixed clamping plate 2. Then, under the staggered opposing clamping of the moving clamping plate 6 and the fixed clamping plate 2, it is ensured that the valve body of the regulating valve can be stably positioned and clamped for vertical drilling.

[0033] The thickness of the guide plate 4 is the same as the thickness of the guide groove 3, and the length of the guide plate 4 is less than the length of the guide groove 3.

[0035] It should be noted that this utility model is a positioning and clamping mechanism for processing a regulating valve. When the regulating valve needs to be vertically drilled, the base plate 1 of this utility model's positioning and clamping mechanism can be placed on the machine table of the drilling equipment. Then, bolts are screwed into the drilling equipment from the hole in the perforated plate 16. The cylindrical valve body of the regulating valve is placed on the surface of the base plate 1, so that the cylindrical valve body of the regulating valve is clamped between the fixed clamping plate 2 and the base plate 1. At this time, the electric push rod 9 can extend the telescopic rod, so that the head plate 8 pushes the tail plate 7 and the moving clamping plate 6 towards the cylindrical valve body of the regulating valve. The guide plate 4 below the moving clamping plate 6 can guide the movement within the guide groove 3 on the surface of the base plate 1. Then, the ramp 13 installed on the surface of the guide plate 4 can... The valve body of the regulating valve is lifted so that its cylindrical shape enters the V-shaped clamping cavity between the ramp 13 and the moving clamp 6. At this time, the regulating valve can be positioned and clamped between the fixed clamp 2 and the moving clamp 6. Then, the drilling device can drill a hole vertically above the regulating valve. After drilling, the electric push rod 9 pulls back the telescopic rod, so that the moving clamp 6 and the ramp 13 are pulled away from the cylindrical valve body of the regulating valve. Then, the regulating valve can be manually removed from between the fixed clamp 2 and the moving clamp 6. The fixed clamp 2 and the moving clamp 6 have a staggered opposing clamping structure, so that the angular cavity formed by the fixed clamp 2 and the base plate 1 can cooperate with the V-shaped clamping cavity between the ramp 13 and the moving clamp 6 to clamp the valve bodies of regulating valves of different diameters.
