Description

Technical Field

[0001] The present application belongs to the technical field of pneumatic valve production, and in particular relates to a pneumatic valve block steel ball pressing positioning fixture. Background Art

[0002] The production process of pneumatic valves involves the process of pressing a steel ball into the valve body of the pneumatic valve. That is, there is a through hole on the valve body of the pneumatic valve, and a steel ball needs to be pressed into the through hole on the valve body of the pneumatic valve. At this time, a steel ball pressing positioning fixture is needed to press the steel ball on the pneumatic valve block.

[0003] The existing utility model with authorization announcement number CN220575170U discloses a steel ball pressing jig for valve body sealing, including a base, support rods are provided at right angles to the base, and a valve body fixing structure is provided at the upper end of the base, a connecting plate is provided at the upper end of the support rod, a power chamber is provided at the upper end of the connecting plate, and a pressing structure is provided in the middle of the lower end of the connecting plate, the pressing structure includes a pressing upper cover, the upper end of the pressing upper cover is fixedly connected to the connecting plate, and the lower end of the pressing upper cover is threadedly connected to the pressing lower cover.

[0004] The above technical solution is adopted, by symmetrically setting the positioning structure in the pressing channel, so that the steel ball entering the pressing channel is placed centrally between the two positioning blocks; through the automatic slide, clamping clamp and pad, the same displacement is achieved in the automatic slide by the two clamping clamps, so that the steel ball installation position of the pressing channel and the valve body is always aligned. However, in the above technical solution, the jig cannot guarantee the depth dimensional accuracy of the steel ball pressed into the valve block. The amount of force will affect the depth of the steel ball pressed into the valve block. When the force is large, the depth dimension of the steel ball pressed into the valve block becomes larger, and when the force is small, the depth dimension of the steel ball pressed into the valve block becomes smaller. The dimensional accuracy of the steel ball pressed into the valve block cannot be guaranteed by adjusting the up and down position of the pressure head of the manual press.

[0005] To this end, we proposed a pneumatic valve block steel ball pressing positioning fixture to solve the above problems. Utility Model Content

[0023] The upper surface of the upper top plate 13 is fixedly connected with a stamping hydraulic rod 14, and the telescopic end of the stamping hydraulic rod 14 passes through the upper top plate 13 and extends to the bottom of the upper top plate 13. The bottom ends of the two groups of support columns 11 and the bottom surfaces of the two protective plates 12 are fixedly connected with the jig chassis 1. The left side of the jig chassis 1 is fixedly connected with a scale 4. Through the jig chassis 1, the pneumatic valve block can be conveniently set on its surface for processing, and the scale 4 can be used to conveniently measure the position of the pneumatic valve block.

[0024] The telescopic end of the stamping hydraulic rod 14 is fixedly connected to the adjustable electric telescopic rod 15, and the bottom surface of the jig chassis 1 is fixedly connected to two groups of support legs 2. The bottom end of each group of support legs 2 is fixedly connected to the support chassis 3. The support structure composed of the two groups of support legs 2 and the support chassis 3 can stably support the jig chassis 1 in the required position.

[0025] The telescopic end of the adjustable electric telescopic rod 15 is fixedly connected to a connecting tube 16, and the outer surface of the connecting tube 16 is threadedly connected to a mounting cover 17. Two L-shaped clamping plates 7 are provided above the jig chassis 1, and the left side of each L-shaped clamping plate 7 is fixedly connected to a moving pointer 8. The indicating end of each moving pointer 8 is in contact with the left side of the scale 4. By sliding the two L-shaped clamping plates 7 on the jig chassis 1, the moving pointer 8 can be moved along the scale 4, thereby further facilitating the measurement of the position of the pneumatic valve block.

[0026] A pressure sensor 18 is clamped inside the connecting tube 16. The pressure sensor 18 is a device or apparatus that can sense pressure signals and convert the pressure signals into usable output electrical signals according to a certain rule. The model of the pressure sensor 18 is PT124B-121. The inner wall of the mounting cover 17 is fixedly connected to the outer surface of the pressure sensor 18. The bottom surface of each L-shaped clamping plate 7 is fixedly connected to two inverted T-shaped sliders 6. Two inverted T-shaped slides 5 are provided on the upper surface of the jig chassis 1.

[0028] The working principle of the utility model is: when in use, first connect the stamping hydraulic rod 14, the adjustment electric telescopic rod 15 and the pressure sensor 18 to the power supply. When the positioning jig is needed to press the steel ball into the pneumatic valve block, the positioning jig is first placed on the horizontal ground manually, and the support structure composed of two groups of support legs 2 and the support chassis 3 is used to stably support the positioning jig in the required position to press the steel ball into the pneumatic valve block. Then, the pneumatic valve block is manually placed between the two L-shaped clamping plates 7 on the jig chassis 1. By moving the two L-shaped clamping plates 7 and using the inverted T-shaped slider 6 to slide in the inverted T-shaped slide groove 5, the pneumatic valve block can be easily and stably slid on the jig chassis 1. When the L-shaped clamping plate 7 moves, the moving pointer 8 can be moved along the jig chassis 1. The scale 4 on the side slides, so as to facilitate the precise positioning of the position of the pneumatic valve block. By manually twisting the positioning bolt 10 in the positioning screw barrel 9, the L-shaped clamping plate 7 can be stably installed on the jig chassis 1, so that the pneumatic valve block can be positioned. Then, the mounting cover 17 is manually installed on the outside of the connecting cylinder 16 and the pressure sensor 18 is installed inside the connecting cylinder 16. By controlling and adjusting the power supply of the electric telescopic rod 15, the upper and lower positions of the punching cylinder 19 are adjusted, and the steel ball conveying hose 20 is used to convey the steel ball into the punching cylinder 19. By controlling the power supply of the punching hydraulic rod 14, the power output by the punching hydraulic rod 14 can be used to drive the steel ball in the punching cylinder 19 to be pressed into the inside of the pneumatic valve block, and the pressure sensor 18 is used to detect the impact force, so as to ensure the depth dimensional accuracy of the steel ball pressed into the valve block.
