Description

Technical Field

[0001] This utility model relates to the field of pump casing processing technology, and in particular to a multi-station synchronous drilling device for pump casings. Background Technology

[0002] A pump casing drilling device is a mechanical or automated device specifically used for drilling holes in the casing of pump equipment. As the core component of a pump, the pump casing's structure is typically designed according to the pump's functional requirements. It may require multiple holes to be machined at different locations and angles for mounting shafts, bolts, pipe connections, and other components. The precision of these holes (such as hole diameter, hole position, and perpendicularity) directly affects the pump's assembly quality and operational performance.

[0003] The existing pump casing drilling device does not have the function of switching between dual-station drilling and thread drilling, which leads to low processing efficiency. When operating in a single station, the drilling and punching process of the pump casing must be completed one by one, and it is impossible to process two workpieces at the same time. Moreover, drilling and tapping (thread drilling) must be completed on different equipment or through cumbersome tool changes. The switching process is time-consuming and labor-intensive, which not only increases the production cycle, but may also cause positioning errors due to multiple clamping, affecting the processing accuracy. In addition, frequent process switching will also increase the intensity of manual operation and reduce the overall production continuity.

[0004] Therefore, in view of the problems that existing pump casing drilling devices lack the function of switching between dual-station drilling and thread drilling, making it impossible to handle two simultaneously, and that drilling and tapping require changing equipment or cumbersome tool changes, which is time-consuming and labor-intensive, thus increasing the production cycle, reducing production continuity, and resulting in low processing efficiency, there is an urgent need to design a new type of pump casing multi-station synchronous drilling device. Utility Model Content

[0005] To overcome the problems of existing pump casing drilling devices lacking dual-station drilling and thread drilling switching functions, which cannot handle two simultaneously, and require changing equipment or cumbersome tool changes for drilling and tapping, which is time-consuming and labor-intensive, thus increasing the production cycle, reducing production continuity, and resulting in low processing efficiency.

[0006] The technical solution of this utility model is as follows: a multi-station synchronous drilling device for pump casing, including a support plate and sliding grooves on the front and rear sides of the support plate. An arc groove is formed near the middle of the sliding grooves on the support plate. A fixed rod is movably connected inside the arc groove. A rubber wheel is connected to the bottom of the fixed rod. Toothed plates are connected to the front and rear sides of the bottom of the support plate. A limiting groove is formed at the top of the toothed plate. The limiting groove is arc-shaped. The fixed rod is located inside the limiting groove. The toothed plate is rotatably connected to the rubber wheel. A gear is rotatably connected to the bottom of the support plate. The gear meshes with the toothed plate. A fixed disk is provided at the bottom of the gear. The fixed disk is movably connected to the rubber wheel. A support frame is rotatably connected to the bottom of the fixed disk. The support frame is connected to the support plate. A bottom shell is connected to the bottom of the support frame. A motor is connected inside the bottom shell. The output end of the motor is connected to the gear via the fixed disk. A placement plate is connected to the top of the fixed rod. The placement plate is used to place the pump casing. The motor drives the gear to rotate. The rotation of the gear drives the toothed plate to slide on the support plate. The movement of the toothed plate causes the rubber wheel to engage with the fixed disk, driving the rubber wheel to rotate the fixed rod within the limiting groove.

[0007] Preferably, a pump casing drilling device with dual-station drilling and thread drilling switching functions is achieved by setting up a support plate, a fixed rod, a rubber wheel, a toothed plate, a fixed plate, and a placement plate in coordination. It can process two pump casings at the same time, greatly increasing the processing volume per unit time and significantly improving production efficiency. The motor drives the gear to rotate, causing the toothed plate to slide on the support plate. The movement of the toothed plate causes the rubber wheel to come into contact with the fixed plate, driving the rubber wheel to rotate and causing the fixed rod to rotate in the limiting groove, thereby adjusting the position and state of the two placement plates. It can achieve dual-station synchronous drilling and can also adapt to the thread drilling requirements by switching positions, meeting the needs of rapid conversion between different processing procedures.

[0008] Preferably, the support plate has two support blocks connected to its left and right ends, and multiple punching machines are connected to the top of the right support block.

[0009] Preferably, a clamping plate is slidably connected to the inside right side of the placement plate. The clamping plate is L-shaped, and an anti-slip plate is connected to the upper left end of the clamping plate.

[0010] Preferably, a fixing plate is connected to the top left side of the placement plate, and the same anti-slip plate is connected to the end of the fixing plate near the clamp.

[0011] Preferably, the placement plate is internally rotatably connected to a lead screw, which is threadedly connected to the clamping plate, and a knob is connected to the left end of the lead screw.

[0012] Preferably, a threaded drilling machine is connected to the top of the left support block. Turning the knob drives the lead screw to rotate inside the placement plate, causing the clamping plate to slide inside the support plate.

[0013] Preferably, a drilling machine is used to drill holes in the pump casing, and a thread drilling machine is used to drill threaded holes in the pump casing.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting up support plates, fixing rods, rubber wheels, toothed plates, fixing discs and placement plates, two pump housings can be processed simultaneously in two workstations, doubling the processing volume per unit time, greatly improving efficiency, shortening the production cycle, and eliminating the need to change equipment or cumbersome tool changes. The process can be quickly switched by switching positions, reducing connection time and operation steps, reducing errors, ensuring processing accuracy, improving production continuity, and saving equipment and labor costs.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5This utility model provides an embodiment of a multi-station synchronous drilling device for pump casing, including a support plate 1 and sliding grooves 21 on the front and rear sides of the support plate 1. An arc-shaped groove 22 is formed in the sliding groove 21 near the middle of the support plate 1. A fixed rod 23 is movably connected inside the arc-shaped groove 22. A rubber wheel 25 is connected to the bottom of the fixed rod 23. Toothed plates 24 are connected to the front and rear sides of the bottom of the support plate 1. A limiting groove 212 is formed at the top of the toothed plate 24. The limiting groove 212 is arc-shaped. The fixed rod 23 is located inside the limiting groove 212. Plate 24 is rotatably connected to rubber wheel 25. A gear 26 is rotatably connected to the bottom of support plate 1, meshing with gear plate 24. A fixed disk 27 is located at the bottom of gear 26, movably connected to rubber wheel 25. A support frame 28 is rotatably connected to the bottom of fixed disk 27, connected to support plate 1. A bottom shell 29 is connected to the bottom of support frame 28, and a motor 210 is connected inside the bottom shell 29. The output end of motor 210 is connected to gear 26 via fixed disk 27. The top of fixed rod 23 is connected to... A placement plate 211 is used to place the pump casing. A motor 210 drives a gear 26 to rotate, which in turn causes a toothed plate 24 to slide on a support plate 1. The movement of the toothed plate 24 causes a rubber wheel 25 to engage with a fixed disc 27, driving the rubber wheel 25 to rotate a fixed rod 23 within a limiting groove 212. By coordinating the support plate 1, fixed rod 23, rubber wheel 25, toothed plate 24, fixed disc 27, and placement plate 211, a pump casing drilling device with dual-station drilling and thread drilling switching functions is achieved. Simultaneous processing of two pump housings significantly increases the processing volume per unit time and greatly improves production efficiency. The motor 210 drives the gear 26 to rotate, causing the toothed plate 24 to slide on the support plate 1. The movement of the toothed plate 24 drives the rubber wheel 25 to fit against the fixed plate 27, driving the rubber wheel 25 to rotate and drive the fixed rod 23 to rotate in the limiting groove 212, thereby adjusting the position and state of the two placement plates 211. This not only enables simultaneous drilling and punching at two workstations, but also allows for adaptation to thread drilling requirements through position switching, satisfying the rapid conversion of different processing procedures.

[0024] Please see Figures 1-5In this embodiment, two support blocks 31 are connected to the left and right ends of the support plate 1. Multiple drilling machines 32 are connected to the top of the right support block 31. A clamping plate 33 is slidably connected to the right side of the placement plate 211. The clamping plate 33 is L-shaped. An anti-slip plate 34 is connected to the upper left side of the clamping plate 33. A fixing plate 35 is connected to the top left side of the placement plate 211. The same anti-slip plate 34 is connected to the end of the fixing plate 35 near the clamping plate 33. The two support blocks 31 provide stable support for the drilling machines 32 and the thread drilling machine 38, ensuring the stability of the equipment during the drilling process. Multiple drilling machines 32 can perform drilling operations at different positions at the same time, improving drilling efficiency. The L-shaped clamping plate 33 cooperates with the fixing plate 35 to clamp the pump housing from both sides. The anti-slip plate 34 increases friction to prevent the pump housing from sliding during processing, ensuring accurate drilling position.

[0025] Please see Figures 2-5 In this embodiment, a lead screw 36 is rotatably connected inside the placement plate 211. The lead screw 36 is threadedly connected to the clamping plate 33. A knob 37 is connected to the left end of the lead screw 36. A thread drilling machine 38 is connected to the top of the left support block 31. Rotating the knob 37 drives the lead screw 36 to rotate inside the placement plate 211, causing the clamping plate 33 to slide inside the support plate 1. The knob 37 provides a convenient operating fulcrum for adjusting the clamping plate 33. By rotating the knob 37 to drive the lead screw 36 to rotate, the sliding distance of the clamping plate 33 can be precisely controlled, realizing the clamping and fixing of pump housings of different sizes and enhancing the adaptability of the device to pump housings of various specifications. The thread drilling machine 38 on the left support block 31 cooperates with the drilling machine 32 on the right side, and can complete drilling and thread processing separately in dual-station operation, further improving the efficiency of process connection.

[0026] During operation, the pump casing is first placed on the placement plate 211. Turning the knob 37 rotates the lead screw 36, causing the L-shaped clamping plate 33 to slide within the placement plate 211. This, in conjunction with the left-side fixing plate 35 and the anti-slip plate 34, clamps the pump casing from both sides. The clamping plate 33 and the anti-slip plate 34 on the fixing plate 35 increase friction, preventing the pump casing from slipping during machining and ensuring drilling accuracy. Simultaneously, by adjusting the position of the clamping plate 33, different sized pump casings can be accommodated, improving the device's versatility. Next, the motor 210 is started via an external controller. After starting, the motor 210 inside the bottom housing 29 drives the gear 26 to rotate. The gear 26 meshes with the toothed plate 24 at the bottom of the support plate 1, causing the toothed plate 24 to slide on the support plate 1. As the two toothed plates 24 move alternately, they drive the bottom of the fixing rod 23... The rubber wheel 25 of the top plate is attached to the fixed plate 27, which allows the fixed rod 23 to rotate in the limiting groove 212 and the arc groove 22, thereby adjusting the position and state of the top plate 211. After the switch is completed, the fixed rod 23 can be positioned by the slide groove 21. When the two plates 211 are adjusted to the corresponding work positions, the drilling machine 32 on the right side can simultaneously drill multiple holes in the pump housing on the plate 211, and the thread drilling machine 38 on the left side can simultaneously complete the thread processing, realizing parallel operation of the two work positions and quickly switching processes by switching positions.

[0027] Through the above steps, components such as support plate 1, fixing rod 23, rubber wheel 25, toothed plate 24, fixing disk 27, and placement plate 211 work together to achieve the function of simultaneously processing two pump casings at two workstations. This doubles the processing volume per unit time, significantly improves production efficiency, and effectively shortens the production cycle. At the same time, there is no need to change equipment or perform cumbersome tool changes. The process conversion can be completed quickly by switching positions, reducing process connection time and operation steps, reducing the possibility of error, ensuring processing accuracy, improving production continuity, and saving equipment investment and labor costs. This solves the problem that existing pump casing drilling devices cannot handle two drilling and thread drilling simultaneously due to the lack of dual-station drilling and thread drilling switching functions. Furthermore, drilling and tapping require changing equipment or performing cumbersome tool changes, which is time-consuming and labor-intensive, increasing the production cycle, reducing production continuity, and resulting in low processing efficiency.
