Description

Technical Field

[0001] This utility model relates to the field of drilling technology, specifically a drilling device for machining the casing of a submersible pump. Background Technology

[0002] In the field of existing automated machining, especially in the drilling of multi-hole parts, automated tool changers have become key equipment for improving production efficiency. Such devices typically include a tool holder with multiple tools, which are picked up and changed by a robotic arm or tool changer according to programmed instructions.

[0003] However, most widely used automated tool changers currently have their tool holders directly exposed on the outside of the equipment or in open spaces. This open structure has significant drawbacks: First, during machining, especially when cutting materials such as cast iron and aluminum alloys, a large amount of cutting fluid, metal shavings, and dust are generated. These impurities may splash or fall onto the exposed tools and tool holders. Second, dust and oil in the workshop environment can also inevitably contaminate the tools. These impurities falling on the tool holders may affect the installation accuracy, thus affecting the machining quality, and may also accelerate tool wear, reducing its service life. Utility Model Content

The telescopic end of the first cylinder 17 moves through the housing 3 and is fixedly connected to the rear end of the clamp 11. When the housing door 10 is opened, the first cylinder 17 can push the tool holder 4 out of the housing 3. The driving assembly includes a second cylinder 7 and a pair of push rods 13. The second cylinder 7 is fixedly arranged on the... On the underside of the workbench 12, the telescopic end of the second cylinder 7 is rotatably connected to one end of a pair of push rods 13, and the other end of the pair of push rods 13 is rotatably connected to the underside of the limiting plate 6; the limiting assembly includes a dovetail block 22, which is disposed on the upper surface of the limiting plate 6, and a dovetail groove 21 is provided on the underside of the workbench 12 corresponding to the position of the dovetail block 22, and the dovetail block 22 is slidably connected to the dovetail groove 21; sliders 16 are provided on both sides of the tool holder 4, and the sliders 16 are slidably connected to the slide groove 23; rubber pads 15 are provided on the facing end faces of the box doors 10; and pads 5 are provided on the workbench 12 at positions corresponding to the clamps 11.

[0022] Its detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, as follows:

[0023] According to the instruction manual Figures 1-5As can be seen, when this utility model is in operation, the submersible pump housing is placed on the worktable 12, or a contoured pad 5 can be set on the worktable 12, and the submersible pump housing is placed on the pad 5. It is clamped and fixed by the clamp 11. The clamp 11 can adopt existing technology, such as a cylinder clamping structure. The drilling machine 8 is controlled to perform three-axis movement by the drive movement system 1. The drive movement system 1 is existing technology and can adopt the cooperation of electric slide rails and cylinders, etc., to adjust the drilling position and perform drilling operations on the submersible pump housing. During drilling, the box door 10 is closed. The box 3 provides a sealed space for the tool holder 4, which avoids the decrease in clamping accuracy and spindle damage caused by impurities in the tool holder, thereby improving the processing quality and tool life. When a tool change is needed, the drive assembly operates, causing the limit plate 6, slide plate 19, and housing door 10 to move outwards and open simultaneously. The first cylinder 17, at its telescopic end, drives the tool holder 4 out of the housing 3 to below the drilling machine 8. The drive movement system 1 on the drilling machine 8 selects an empty position to lower the drill bit 9, selecting the desired replacement drill bit 9. This process can be achieved using existing technology. After replacing the drill bit 9, the first cylinder 17 pulls the tool holder 4 back into the housing 3, and the drive assembly drives the housing door 10 to close, allowing subsequent drilling operations to proceed. This invention automates the opening of the door and the delivery of the tool, eliminating contamination of the tool and tool holder by impurities generated during processing without affecting tool changes.

[0024] The drive assembly includes a second cylinder 7 and a pair of push rods 13. The second cylinder 7 is fixedly mounted on the lower surface of the worktable 12. The telescopic end of the second cylinder 7 is rotatably connected to one end of the pair of push rods 13, and the other end of the pair of push rods 13 is rotatably connected to the lower surface of the limiting plate 6. During operation, when the second cylinder 7 drives one end of the push rod 13 to move downward, the other end of the push rod 13 pulls the limiting plate 6, the slide plate 19, and the door 10 inward. Conversely, when the second cylinder 7 drives one end of the push rod 13 to move upward, the other end of the push rod 13 pushes the limiting plate 6, the slide plate 19, and the door 10 outward. The drive assembly has a simple structure and is easy to maintain and repair.

[0025] The limiting component includes a dovetail block 22, which is set on the upper surface of the limiting plate 6. A dovetail groove 21 is provided on the bottom surface of the worktable 12 at the position corresponding to the dovetail block 22. The dovetail block 22 is slidably connected to the dovetail groove 21 to ensure the stability of the movement of the limiting plate 6, the slide plate 19 and the door 10.

[0026] The tool holder 4 is provided with sliders 16 on both sides, and the sliders 16 are slidably connected to the slide groove 23 to ensure the stability of the movement of the tool holder 4.
