Description

Technical Field

[0001] This invention relates to the field of water pump technology, specifically to a uniform drilling device and method for processing water pump covers. Background Technology

[0002] Water pumps are commonly used equipment in industrial and agricultural production activities. They consist of basic components such as the pump body, pump shaft, impeller, and sealing device. The pump cover is an important part of the sealing device, preventing liquid leakage and protecting internal parts from the influence of the external environment. The pump cover is mainly a cylindrical shape with one open side, and its circumference needs to be perforated in a ring array. These holes are usually described as side holes. Traditional drilling equipment faces three problems when drilling pump covers: first, the cylindrical structure is not easy to fix stably; second, it is difficult to ensure the uniformity of drilling; and third, to avoid the above problems as much as possible, experienced workers need to stay by the equipment for a long time, resulting in low automation. Given this situation, how to achieve stable fixing of the pump cover, ensure the uniformity of drilling, and improve the automation of drilling has become an increasingly urgent problem for relevant technicians to solve. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides a uniform drilling device and a drilling method for processing water pump covers.

[0004] A uniform drilling device for processing water pump covers includes a lower die and an upper die, with the upper die located above the lower die. The lower die includes a base plate, a fixed seat fixedly mounted on the upper part of the base plate, a fixed shaft fixedly mounted in the middle of the fixed seat, a punch fixedly mounted on the upper part of the fixed shaft, a punch groove inside the punch seat, a rotating wheel mounted behind the punch seat, the rotating wheel being rotatably connected to the fixed shaft, a protruding ring at the front of the rotating wheel, and teeth arranged in a circular array around the outer periphery of the rotating wheel in a counter-clockwise centrifugal shape. A punch rod and a push column are fixedly mounted on the lower part of the upper die. The punch rod is located directly above the punch groove, and the push column is located to the right of the rotating wheel. A push block is fixedly mounted inside the push column, and the push block corresponds to the position of the teeth.

[0005] Furthermore, a pressure cap is provided directly in front of the rotating wheel, an mounting plate is fixedly provided at the front of the base plate, a cylinder is fixedly provided at the front of the mounting plate, the output end of the cylinder extends backward through the mounting plate, a central shaft is fixedly provided at the output end of the cylinder, and the central shaft is rotatably connected to the center position of the pressure cap.

[0006] Furthermore, a rotating ring is provided between the rotating wheel and the fixed base. The rotating ring has a circular array of holes arranged through it. A bead is placed inside the hole. Limiting grooves are provided at corresponding positions of the rotating wheel, the fixed base, and the bead. The bead is in rolling connection with the limiting groove.

[0007] Furthermore, a side plate is fixedly installed on the left side of the front part of the fixed base, a bolt is horizontally installed inside the side plate, a locking block is installed to the right of the bolt, a spring is sleeved around the bolt, and the two ends of the spring are fixedly connected to the side plate and the locking block respectively. Under the action of the spring, the locking block is engaged with the teeth.

[0008] Furthermore, the right end of the lock block has a bend design, with the upper part of the end tilting from the upper left to the lower right and the lower part tilting from the upper right to the lower left.

[0009] Furthermore, a middle plate is fixedly installed on the upper part of the fixed base, and a first limiting hole and a second limiting hole are provided through the middle plate. The push rod is slidably inserted into the first limiting hole, and the punch rod is slidably inserted into the second limiting hole.

[0010] Furthermore, a straight groove is provided at the front of the fixed base, the push column is slidably connected to the straight groove, and a pad is fixedly provided on the upper part of the base plate, the pad being located directly below the push column.

[0011] Furthermore, a through hole is provided inside the fixed shaft at the position corresponding to the punch groove, and a drain hole is provided inside the base plate at the position corresponding to the punch groove.

[0012] Furthermore, a drilling method for a uniform drilling device used to process water pump covers is as follows: (1) In the initial state, the upper mold and push column are at the highest point of their own stroke. The water pump cover to be punched is fastened on the convex ring. At this time, the inner wall of the water pump cover is in contact with the punch seat. Start the cylinder. The output end of the cylinder pushes the central shaft and the pressure cover to move backward until the pressure cover is in contact with the water pump cover. (2) Move the upper mold down. Under the sliding limit of the straight groove and the first limiting hole, the pusher moves vertically down until it is in contact with the pad. During this process, the pusher pushes the tail end of the rightmost tooth to make the wheel rotate clockwise. Correspondingly, the leftmost tooth pushes the locking block to move in the direction of the bolt. When the wheel rotates through the angle of one tooth, the locking block is reset under the action of the spring. The wheel remains stable under the double limit of the pusher and the locking block. At this time, the pusher is in contact with the pad, and the lower end of the punch penetrates the predetermined drilling position of the water pump cover and is inserted into the punch groove. (3) In the previous step, the pressure cap, water pump cover, wheel and rotating ring rotate synchronously, and the rolling connection between the ball and the limiting groove makes this synchronous rotation process proceed smoothly; (4) The scrap material that is flushed out leaks out through the through hole inside the fixed shaft and the leakage hole inside the bottom plate; (5) Move the upper mold up until it is reset. During this process, the push block pushes the rightmost tooth. Under the action of friction, the wheel rotates slightly counterclockwise. The angle design of the right end of the locking block, especially the inclined design of the upper part of the right end, combined with the contraction of the spring, makes the slight counterclockwise rotation of the wheel proceed smoothly. Then the push column can be reset smoothly, and the wheel automatically returns to the state before the slight counterclockwise rotation. This completes one side hole drilling operation. (6) Repeat the above process until the side holes on the entire circumference of the pump cover are completed.

[0013] The beneficial effects of the uniform drilling device and drilling method for processing water pump covers according to the present invention are as follows: The punch seat and convex ring provide a good structural foundation for the stable placement of the water pump cover. The cylinder, central shaft, and pressure cap provide a further structural foundation for the stable placement of the water pump cover. The rotating ring, round hole, ball, and limiting groove provide a good structural foundation for the stable rotation of the rotating wheel and water pump cover. The push column and push block provide a good structural foundation for the equidistant rotation between adjacent side holes of the water pump cover. The push block and locking block provide a good structural foundation for the stability of the water pump cover during the drilling process. Thus, the water pump cover is stably fixed and the uniformity of drilling is ensured. After feeding, drilling can be completed simply by moving the upper die up and down. Experienced workers no longer need to stay by the equipment for a long time, and the degree of automation is significantly improved. Attached Figure Description

A punch rod 10 and a push column 9 are fixedly mounted at the lower part of the upper mold 1. The punch rod 10 is located directly above the punch groove, and the push column 9 is located to the right of the rotating wheel 7. A push block 8 is fixedly mounted inside the push column 9, and the push block 8 corresponds to the position of the teeth 25.

[0019] Furthermore, a pressure cover 11 is provided in front of the rotating wheel 7, an mounting plate 3 is fixedly provided in front of the base plate 12, a cylinder 4 is fixedly provided in front of the mounting plate 3, the output end of the cylinder 4 extends backward through the mounting plate 3, a central shaft 13 is fixedly provided in front of the output end of the cylinder 4, and the central shaft 13 is rotatably connected to the center position of the pressure cover 11.

[0020] Furthermore, a rotating ring 26 is provided between the rotating wheel 7 and the fixed base 16. The rotating ring 26 has a circular array of through holes 27 inside. A bead 30 is provided inside the hole 27. A limiting groove 29 is provided at the corresponding positions of the rotating wheel 7, the fixed base 16 and the bead 30. The bead 30 is in rolling connection with the limiting groove 29.

[0021] Furthermore, a side plate 6 is fixedly installed on the left side of the front part of the fixed base 16, a bolt 28 is horizontally installed inside the side plate 6, a locking block 5 is installed to the right of the bolt 28, and a spring is sleeved around the bolt 28. The two ends of the spring are fixedly connected to the side plate 6 and the locking block 5 respectively. Under the action of the spring, the locking block 5 is engaged with the tooth 25.

[0022] Furthermore, the right end of the locking block 5 has a bend design, with the upper part of this end tilting from the upper left to the lower right and the lower part tilting from the upper right to the lower left.

[0023] Furthermore, a middle plate 19 is fixedly installed on the upper part of the fixed base 16. A first limiting hole 17 and a second limiting hole 18 are provided through the middle plate 19. The push column 9 is slidably inserted into the first limiting hole 17, and the punch rod 10 is slidably inserted into the second limiting hole 18.

[0024] Furthermore, a straight groove 21 is provided at the front of the fixed base 16, the push column 9 is slidably connected to the straight groove 21, and a pad 15 is fixedly provided on the upper part of the base plate 12, the pad 15 being located directly below the push column 9.

[0025] Furthermore, a through hole is provided inside the fixed shaft 23 at the position corresponding to the punch groove, and a drain hole 14 is provided inside the base plate 12 at the position corresponding to the punch groove.

[0026] Furthermore, a drilling method for a uniform drilling device used to process water pump covers is as follows: (1) In the initial state, the upper mold 1 and the push column 9 are at the highest point of their own stroke. The water pump cover 20 to be punched is fastened on the convex ring 31. At this time, the inner wall of the water pump cover 20 is in contact with the punch seat 24. The cylinder 4 is started. The output end of the cylinder 4 pushes the central shaft 13 and the pressure cover 11 to move backward until the pressure cover 11 is in contact with the water pump cover 20. (2) Move the upper mold 1 down. Under the sliding limit of the straight groove 21 and the first limiting hole 17, the pusher 9 moves vertically down until it is in contact with the pad 15. During this process, the pusher 8 pushes the tail end of the rightmost tooth 25 to make the rotating wheel 7 rotate clockwise. Correspondingly, the leftmost tooth 25 pushes the locking block 5 to move towards the bolt 28. When the rotating wheel 7 rotates through the angle of one tooth 25, the locking block 5 is reset under the action of the spring. The rotating wheel 7 remains stable under the double limit of the pusher 8 and the locking block 5. At this time, the pusher 9 is in contact with the pad 15, and the lower end of the punch rod 10 penetrates the predetermined drilling position of the water pump cover 20 and is inserted into the punch groove. (3) In the previous step, the pressure cap 11, water pump cover 20, rotating wheel 7, and rotating ring 26 rotate synchronously. The rolling connection between the ball 30 and the limiting groove 29 makes this synchronous rotation process proceed smoothly. (4) The waste material that is flushed out leaks out along the through hole inside the fixed shaft 23 and the leakage hole 14 inside the bottom plate 12; (5) Move the upper mold 1 up until it is reset. During this process, the push block 8 pushes the rightmost tooth 25. Under the action of friction, the rotating wheel 7 rotates slightly counterclockwise. The angle design of the right end of the locking block 5, especially the inclined design of the upper part of the right end, combined with the contraction of the spring, makes the slight counterclockwise rotation of the rotating wheel 7 proceed smoothly. Then the push column 9 can be reset smoothly. The rotating wheel 7 automatically returns to the state before the slight counterclockwise rotation. Thus, the drilling of the side hole 22 is completed. (6) Repeat the above process until the drilling of the side holes 22 on the entire circumference of the water pump cover 20 is completed.

[0027] The working principle of the uniform drilling device and drilling method for processing water pump cover of the present invention is as follows: by performing the steps (1)-(6) of the above drilling method, the drilling of the side hole 22 on the circumferential surface of the water pump cover 20 can be completed smoothly with a high degree of automation, and the stability of the water pump cover 20 and the uniformity of drilling are ensured during the process.

[0028] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions conceived without inventive effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
