Abstract
Description
Technical Field
[0001] This utility model relates to the field of automatic feeding devices, and in particular to an automatic feeding device for blanks used in the production of oil perforation projectiles. Background Technology
[0002] Oil perforation projectiles are key equipment in the oil and gas exploration and development process. They are mainly used to perforate the casing and formation rock of oil and gas wells, establishing a channel between the wellbore and the oil and gas layer, allowing underground oil and gas to flow smoothly into the wellbore and be extracted. Their performance directly affects perforation efficiency and the production capacity of oil and gas wells; therefore, extremely high requirements are placed on processing precision, consistency, and safety during production. The casing of the oil perforation projectile, as the core structural component of the projectile body, is usually made from metal blanks and requires multiple processes such as forging, cutting, and heat treatment. Precise feeding of the blank is a crucial prerequisite for ensuring the quality of subsequent processing. In the production process of oil perforation projectile casing blanks, the automatic feeding device plays a critical role in accurately transferring the blank from the storage area to the processing equipment (such as lathes and milling machines).
[0003] In actual production, oil perforating projectiles need to be designed in various specifications and models according to different well depths, formation characteristics, and casing specifications. The diameter, length, wall thickness, and other parameters of their shell blanks vary significantly. For example, the small-diameter perforating projectile shells developed for shallow wells may differ in size by several times from the large-diameter shells used for deep and ultra-deep wells. In this case, the adaptability of the automatic feeding device to clamp shell blanks of different specifications is particularly important. Traditional automatic feeding devices often use fixed-size clamping structures. When processing shell blanks of different specifications, the machine must be stopped to replace the clamping components, increasing equipment adjustment time and reducing production efficiency. In addition, although some adjustable clamping devices can achieve size adjustments within a certain range, the adjustment process is complex. Therefore, this application proposes an automatic feeding device for oil perforating projectile blanks to solve the above problems. Utility Model Content

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0020] Please see Figure 1 - Figure 5As shown, an automatic feeding device for producing oil perforating projectile blanks includes a Z-axis drive component 4. A pneumatic clamping component 5 is fixedly mounted on the Z-axis drive component 4. The pneumatic clamping component 5 includes three grippers 9 arranged in a ring. A positioning rack 11 and a limiting component 10 are fixedly mounted inside the grippers 9. The limiting component 10 is located above the positioning rack 11 and is composed of a spring 14 and a baffle 15. There are two springs 14, which are symmetrically fixedly mounted on the upper end of the baffle 15. An adjustable clamping component 12 is mounted on the grippers 9, the positioning rack 11, and the limiting component 10. The adjustable clamping component 12 consists of an arc-shaped base block 16, a positioning rack 17, and an arc-shaped rubber. The device consists of a pad 18 and an arc-shaped rubber strip 19. Two positioning tooth plates 17 are symmetrically fixedly installed at one end of the arc-shaped base block 16. The arc-shaped rubber pad 18 is fitted onto the arc-shaped base block 16. Two arc-shaped rubber strips 19 are symmetrically fixedly installed on the inner wall of the arc-shaped rubber pad 18. The arc-shaped rubber strips 19 are also embedded in the arc-shaped base block 16. By setting a positioning tooth 11 on the gripper 9, cooperating with the limiting member 10 composed of a spring 14 and a baffle 15, and the adjustable clamping member 12 composed of the arc-shaped base block 16, the positioning tooth plate 17, the arc-shaped rubber pad 18 and the arc-shaped rubber strip 19, a flexible and adaptable clamping adjustment mechanism is formed. The adjustable clamping component 12 can be easily adjusted on the gripper 9 to precisely adapt to the diameter differences of oil perforation projectile shell blanks of different specifications, achieving stable clamping. The meshing of the positioning rack 11 and the positioning toothed plate 17, combined with the elastic pressing effect of the limiting component 10, can not only firmly lock the adjustable clamping component 12 to prevent displacement during operation, but also quickly complete the position adjustment operation. This design significantly shortens the equipment adjustment cycle when changing oil perforation projectile shell blanks of different specifications, effectively reduces downtime, significantly improves production continuity and overall processing efficiency, and better meets the requirements of equipment adaptability and operational efficiency in the mass production of oil perforation projectiles.
[0021] Specifically, the Z-axis drive 4 is fixedly mounted on the Y-axis drive 3, the Y-axis drive 3 is fixedly mounted on the X-axis drive 2, and the X-axis drive 2 is fixedly mounted on the upper end of the worktable 1 via a bracket. The pneumatic clamping component 5 includes a mounting bracket 6, a clamping component body 7, and a connecting frame 8. The clamping component body 7 is fixedly mounted on the mounting bracket 6, the mounting bracket 6 is fixedly mounted on the Z-axis drive 4, and the connecting frame 8 is fixedly mounted on the clamping component body 7. The gripper 9 is rotatably mounted on the connecting frame 8. Two symmetrical receiving grooves 13 are opened at both ends of the gripper 9. The positioning rack 11 is fixedly mounted on the lower inner wall of the receiving groove 13. The limiting component 10 is... Spring 14 is fixedly installed on the upper inner wall of receiving groove 13. Baffle 15 is movably installed in receiving groove 13. Arc-shaped base block 16 on adjustable clamping member 12 is located inside clamping jaw 9. Positioning tooth plate 17 is located in receiving groove 13 and is also located at the lower end of baffle 15. Positioning tooth plate 17 meshes with positioning rack 11. Two arc-shaped slots 20 are symmetrically opened on the outer wall of arc-shaped base block 16. Arc-shaped rubber strip 19 is fixedly embedded in arc-shaped slots 20. The tooth density of positioning tooth plate 17 and positioning rack 11 can be set according to the required precision. If a higher precision clamping position adjustment is required, a smaller tooth pitch can be selected. The positioning rack 11 and positioning toothed plate 17 allow for finer positional adjustments during engagement, enabling the adjustable clamping member 12 to more precisely adapt to oil perforation cartridge blanks of different diameters, ensuring accurate clamping. The spring 14 must possess sufficient elasticity to stably press the positioning toothed plate 17 through the baffle 15, ensuring tight engagement between the positioning toothed plate 17 and the positioning rack 11. Even if vibrations occur during operation due to the movements of the X-axis drive 2, Y-axis drive 3, and Z-axis drive 4, the adjustable clamping member 12 will not shift or wobble due to vibration, ensuring stable clamping of the blank and preventing interference. The accuracy and safety of automatic feeding are ensured; the main body 7 of the clamping component is a conventional pneumatic clamping device, which contains standard pneumatic drive components such as cylinders, pistons and transmission rods. It can drive the three grippers 9 to open and close synchronously through the pneumatic power provided by an external air source, so as to realize the clamping and release of the oil perforation shell blank. Its working principle and control method conform to the general standard of conventional pneumatic clamping devices in the industry. There is no need to design a special drive structure. It can ensure the stability and response speed of the clamping action, reduce the overall manufacturing cost of the device, and facilitate the operation and maintenance of operators based on their experience in using existing pneumatic equipment.
[0022] When using the automatic feeding device for oil perforation shell blanks, the X-axis drive 2, Y-axis drive 3, and Z-axis drive 4 work together to move the pneumatic clamping member 5 to the blank storage area. Then, the clamping body 7 of the pneumatic clamping member 5 drives the three jaws 9 to rotate via the connecting frame 8, causing the arc-shaped rubber pad 18 of the adjustable clamping member 12 to contact and stably clamp the blank. Next, the X-axis drive 2, Y-axis drive 3, and Z-axis drive 4 work together again to move the clamped blank to the designated position on the processing equipment. Finally, the clamping body 7 drives the jaws 9 to open, completing the automatic feeding of the blank. When it is necessary to adjust the position of the adjustable clamping member 12 according to the diameter of blanks of different specifications, first push the adjustable clamping member 12 upwards so that the positioning teeth... Plate 17 moves upward within the receiving groove 13, disengaging the positioning toothed plate 17 from the positioning rack 11. At this point, the positioning toothed plate 17 pushes the baffle 15 to compress the spring 14, which in turn pushes the adjustable clamping member 12 inward or outward, thereby changing the engagement position of the positioning toothed plate 17 and the positioning rack 11 until the positions of the three arc-shaped rubber pads 18 on the three adjustable clamping members 12 are adapted to the diameter of the oil perforation cartridge blank. Finally, the adjustable clamping member 12 is adjusted, and the spring 14 returns to its original position, pushing the baffle 15. The baffle 15 then pushes the positioning toothed plate 17 downward until the positioning toothed plate 17 engages with the positioning rack 11. At this point, the position of the adjustable clamping member 12 is fixed, thus completing the position adjustment of the adjustable clamping member 12.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
