Description

Technical Field

[0001] The utility model relates to the technical field of valve stem processing, in particular to a valve stem punching device. Background Art

[0002] Valves are important control devices in piping systems, achieving functions such as diversion, shutoff, throttling, check valves, diversion, or overflow pressure relief by changing the cross-section of the channel and the flow direction of the medium. Valves come in a wide variety of types and specifications, suitable for controlling various types of fluids, including water, steam, oil, gas, mud, various corrosive media, liquid metals, and radioactive fluids. When using a valve, the valve stem is used to precisely control the flow rate and flow state of the fluid;

[0003] After searching, a Chinese patent with publication number CN216065655U discloses a punching device for valve stem processing. The patent describes a technical solution for punching valve stems by providing a base, a fixed plate, a threaded rod, a first motor, a moving block, a clamping member, and an indicator plate. The moving block is controlled to move, thereby driving the clamping member to move the valve stem. The moving distance is controlled according to the scale indicated by the indicator plate, thereby ensuring the accurate punching distance and punching accuracy. The valve stem can be punched by providing a column, a hydraulic cylinder, a second motor, and a punching head.

[0004] In this solution, although the drilling distance can be guaranteed to be accurate, when fixing different valve stems, it cannot ensure that the different valve stems remain stable during processing. The device can only be adapted to the same valve stem as the fixing device, which is relatively limited during processing and cannot adapt to the processing of different valve stems, resulting in a significant reduction in work efficiency. In order to solve this technical problem, the utility model proposes a valve stem drilling device. Summary of the Invention

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] See also Figure 1-4 , the utility model provides a technical solution:

[0026] Embodiment 1: A valve stem punching device includes a workbench 1, and a clamping mechanism 2 is fixedly connected to the top of the workbench 1. The clamping mechanism 2 includes a pair of bases 201 and a pair of fixed support plates 204. The bases 201 on both sides are fixedly connected to the top of the workbench 1, and the fixed support plate 204 is fixedly connected to the top of the workbench 1. The bases 201 on both sides are distributed on both sides of the right fixed support plate 204. The outer wall of the base 201 on one side is fixedly connected to a motor 1 202. The output end of the motor 1 202 is fixedly connected to a threaded rod 203. The motor 1 202 is rotatably connected to the base 201 and the left fixed support plate 204. A pair of connecting blocks 205 are provided on the outer wall of the right fixed support plate 204. At the same time, the connecting block 205 on one side is threadedly connected to the outer wall of the threaded rod 203, and the connecting block 205 on the other side is slidably connected to a positioning rod 203. Rod 206, the positioning rod 206 is fixedly connected to the base 201 on the other side, the right side fixed support plate 204 is slidably connected to the top of the workbench 1, and circular connecting plates 207 are provided on the outside of the fixed support plates 204 on both sides. Clamping components are provided on the circular connecting plates 207 on both sides. The clamping components include fixed plates 208, and the fixed plates 208 are respectively fixedly connected to the outer walls of the circular connecting plates 207 on both sides. At the same time, the internal threaded connection of the fixed plates 208 is connected with a screw 209, and a pair of upper clamping plates 210 and lower clamping plates 211 are provided on the outside of the circular connecting plates 207, and the screw 209 passes through the fixed plate 208 and is rotatably connected in the upper clamping plate 210, and the upper clamping plate 210 corresponds to the lower clamping plate 211.

[0027] By adjusting the length of the valve stem, the motor 202 outside the base 201 is started, and the motor 202 drives the threaded rod 203 to rotate, thereby driving the connecting block 205 to move left and right. The movement of the connecting block 205 causes the right side fixed support plate 204 to move left and right to adjust the position and length of the valve stem. When moving, the right side fixed support plate 204 is limited to the positioning rod 206 by the connecting block 205 on the other side to ensure the consistency and accuracy of the movement direction. At the same time, the valve stem is placed on the lower clamping plate 211 on the outer wall of the circular connecting plate 207. By rotating the screw 209 on the fixed plate 208, the screw 209 enables the upper clamping plate 210 to move up and down. This design allows the position of the upper clamping plate 210 to be adjusted according to the thickness of the valve stem, thereby ensuring that the valve stem is firmly fixed. This mechanism realizes the rapid adjustment and fixation of different valve stems, significantly improving work efficiency and stability during processing.

[0028] Embodiment 2: The difference between this embodiment and embodiment 1 is that, a rotating mechanism is provided on the top of the workbench 1, and the rotating mechanism includes an inner rod 9, a rotating rod 10 and a bearing 11. The left circular connecting plate 207 is fixedly connected to the outer wall of the right end of the inner rod 9, and the right circular connecting plate 207 is fixedly connected to the outer wall of the left end of the rotating rod 10. At the same time, the outside of the rotating rod 10 is fixedly connected to the bearing 11, and the bearing 11 is fixedly connected to the inside of the right fixed support plate 204. The top of the workbench 1 is fixedly connected to an electric push rod 4, and the output end of the electric push rod 4 is fixedly connected to a positioning plate 6. At the same time, a rack 7 is fixedly connected to the outer wall of the other end of the positioning plate 6. The top of the workbench 1 is fixedly connected to a slide plate 5, and the bottom of the rack 7 is fixed. A limit block 3 is fixedly connected, and the limit block 3 is slidably connected in the slide plate 5. At the same time, a gear 8 is fixedly connected to the outer wall of the left end of the inner rod 9, and the gear 8 is engaged with the rack 7. At the same time, the inner rod 9 is rotatably connected to the left fixed support plate 204. The top of the workbench 1 is fixedly connected to a bracket 12, and the top of the bracket 12 is fixedly connected to a hydraulic rod 13. The output end of the hydraulic rod 13 is fixedly connected to a limit block 2 14, and the limit block 2 14 is slidably connected to the top of the bracket 12, and the bottom of the limit block 2 14 is fixedly connected to an electric push rod 2 15, and the output end of the electric push rod 2 15 is fixedly connected to a mounting plate 16, and the bottom of the mounting plate 16 is fixedly connected to a motor 2 17. At the same time, the output end of the motor 2 17 is fixedly connected to a punching head 18.

[0029] By activating electric push rod 1 (4), positioning plate 6 is pushed and moved, causing rack 7 to move on chute plate 5. Rack 7 is constrained by stop block 1 (3) to maintain consistent direction. The movement of rack 7 rotates the internally meshed gear 8, which in turn rotates the internal rod 9, thereby rotating the circular connecting plate 207. This action simultaneously affects the valve stem on the lower clamping plate 211, as well as the coordinated movement between the right circular connecting plate 207 and the rotating rod 10. Together, these components enable multi-faceted machining of the valve stem. Simultaneously, the top hydraulic rod 13 is activated, pushing stop block 2 (14). The movement of stop block 2 (14) causes electric push rod 2 (15) to move left and right. The action of electric push rod 2 (15) causes mounting plate 16 to move downward, in turn driving the punch head 18 on motor 2 (17) downward. Simultaneously, motor 2 (17) rotates the punch head 18, completing the drilling of the valve stem. The synergistic effect of these operations significantly improves the efficiency and accuracy of the machining process.

[0030] Working principle: when the staff needs to process and punch the valve stem, they first adjust it according to the length of the valve stem. At this time, the motor 1 202 outside the base 201 is started. Under the action of the motor 1 202, the threaded rod 203 is driven to rotate, and the connecting block 205 is driven to move left and right. When the connecting block 205 moves, it drives the right fixed support plate 204 to move left and right. When the connecting block 205 moves, it drives the right fixed support plate 204 to move toward the left fixed support plate 204, thereby adjusting according to the length of the valve stem. When the right fixed support plate 204 moves, The connecting block 205 on the other side is limited on the positioning rod 206 to ensure the same moving direction. At this time, the valve stem is placed on the lower clamping plate 211 of the outer wall of the circular connecting plate 207. By rotating the screw 209 on the fixing plate 208, the upper clamping plate 210 is driven up and down under the action of the screw 209, so that it can be fixed according to the thickness of the valve stem. Through the cooperation between them, different valve stems can be quickly fixed, which improves the work efficiency and stability during processing. After the fixation is completed, the electric push rod 4 is started to drive the upper clamping plate 210 under the action of the electric push rod 4. The positioning plate 6 moves, and the movement of the positioning plate 6 will drive the rack 7 to move on the slide plate 5. At the same time, the rack 7 is limited in the slide plate 5 by the limit block 3, so that the rack 7 keeps the same direction when moving. The movement of the rack 7 will drive the internal meshing gear 8 to rotate. When the gear 8 rotates, it will drive the internal inner rod 9 to rotate, thereby driving the circular connecting plate 207 to rotate, thereby driving the valve stem on the lower clamping plate 211 to rotate. At the same time, the circular connecting plate 207 on the right will drive the rotating rod 10 to rotate, and the rotating rod 10 rotates on the right side through the bearing 11. Inside the fixed support plate 204, through the cooperation between them, the processing of different surfaces of the valve stem is realized. By starting the hydraulic rod 13 on the top of the bracket 12, the limit block 2 14 is driven to move under the action of the hydraulic rod 13, and the movement of the limit block 2 14 will drive the electric push rod 2 15 to move left and right. At this time, the electric push rod 2 15 is started to push the mounting plate 16 downward, thereby driving the punching head 18 on the motor 2 17 to move downward, and cooperating with the starting motor 2 17 to drive the punching head 18 to rotate, thereby punching the valve stem. Through the cooperation between them, the work efficiency is greatly improved.
