Description

Technical Field

[0001] This application relates to the technical field of pump body drilling and grinding, and particularly to a drilling device for processing the pump body of a vertical marine pump. Background Art

[0002] As a key component in the ship system, the pump body of a vertical marine pump is widely used in the liquid transportation systems of various ships. Its main function is to provide stable and reliable transportation and circulation services for liquids such as water, fuel oil, and lubricating oil on the ship.

[0003] During the processing of the pump body of a marine vertical pump, drilling and grinding the holes are key processes. Special fixture tooling is usually used during processing to ensure the stability and processing accuracy of the pump body. The fixture tooling generally includes a base and a clamping device. The base is used to fix the pump body and usually has adjustable support blocks to adapt to pump bodies of different sizes. The clamping device can adopt hydraulic or mechanical clamping methods to firmly fix the pump body on the base and prevent it from moving during the processing.

[0004] However, there is a potential problem in this process: debris may accumulate in the holes, and at the same time, too much debris may accumulate on the workbench. When cleaning the debris, it may also cause the operator to inhale tiny debris. These debris will not only affect the processing accuracy but may also generate greater stress when the drill bit or other processing tools contact the pump body. Due to the accumulation of debris, the drill bit may encounter uneven resistance when entering or exiting the hole, resulting in an increase in the friction force between the processing tool and the pump body. This uneven stress distribution will cause the pump body to be in an unstable stress state during processing, which will in turn cause the vertical pump to sway or shake. This kind of shaking will not only affect the processing quality but may also cause additional wear to the processing equipment, and even affect the performance and service life of the final product. There is also a possibility of posing health hazards to the operator. Summary of the Invention

[0005] In order to reduce the possibility of debris accumulation in the drilling holes causing the pump body to shake, this application provides a drilling device for processing the pump body of a vertical marine pump.

The collection cylinder includes two hollow cylinders evenly divided along the height direction of the pump body, and the two hollow cylinders are connected to each other to form a blanking cavity. The collection cylinder is coaxially arranged below the annular platform where the pump body needs to be drilled. A fixing assembly is also provided on the periphery of the collection cylinder, and the fixing assembly is used to press the collection cylinder against the side wall of the pump body.

[0018] By adopting the above technical solution, the second mounting seat can drive the support telescopic rod and the lifting drive to move close to or away from the pump body along the bracket. When adjusting the position of the second mounting seat on the bracket, release the fixation of the second fixing member on the second mounting seat, adjust the position of the second mounting seat, and finally use the second fixing member to fix the second mounting seat.

[0019] Optionally, a clamping strip is provided inside the sealing cover. A plurality of clamping grooves are equidistantly arranged on the clamping strip. The clamping grooves are arc-shaped through grooves, and the adjusting ring is clamped in the clamping grooves.

Detailed implementation manners

[0037] The following is further detailed description of the present application in conjunction with Figures 1-7 to the present application.

[0038] An embodiment of the present application discloses a drilling device for machining a pump body of a vertical marine pump. Referring to Figure 1 and Figure 2 , a drilling device for machining a pump body of a vertical marine pump includes a workbench 1, a clamping assembly 2, a collection cylinder 3 and a surrounding assembly 4 arranged on the workbench 1. A placement hole 11 is opened at the top of the workbench 1. The clamping assembly 2 is located near the placement hole 11 on the workbench 1. The clamping assembly 2 is used to fix one end of the pump body in the placement hole 11.

[0039] Referring to Figure 2 and Figure 3, the clamping assembly 2 includes a clamping member 21, a locking ring 22 and a locking drive 23. The clamping member 21 includes a plurality of clamping blocks 211 and an elastic ring 212 provided on the clamping blocks 211. The plurality of clamping blocks 211 are circumferentially spaced along the axis of the pump body. The locking ring 22 is sleeved on the outer peripheral side of the plurality of clamping blocks 211 and is threadedly connected to the clamping blocks 211. The thickness of the locking ring 22 is greater than the thickness of the clamping blocks 211. The side walls of the locking ring 22 that are in contact with the clamping blocks 211 are both conical surfaces. So that when the locking ring 22 rotates, as the locking ring 22 rotates, the locking ring 22 can rise or fall along the clamping blocks 211, and the clamping blocks 211 are also tightened as the locking ring 22 rises and falls. In this embodiment, there are six clamping blocks 211. The elastic rings 212 are all snap-connected to the clamping blocks 211 through card slots. The elastic rings 212 are rubber rings. A first buffer block 213 is bonded to the end of the clamping block 211 away from the locking ring 22. The first buffer block 213 is a rubber block, which reduces the possibility of scratching the pump body on the one hand and increases the friction between the clamping block 211 and the pump body on the other hand.

[0040] Refer to Figure 2 and Figure 3 , the locking drive 23 is connected to the locking ring 22. The locking drive 23 is used to drive the locking ring 22 to rotate so that the locking ring 22 pushes the clamping blocks 211 towards the pump body until the clamping blocks 211 press against the pump body. The locking drive 23 includes a toothed ring 231, a gear 232 and a rotation drive 233. The toothed ring 231 is welded to the outer peripheral side of the locking ring 22.

[0049] The implementation principle of a drilling device for processing the pump body of a vertical marine pump in an embodiment of the present application is as follows: When drilling the pump body, the clamping assembly 2 is used to fix the bottom of the pump body. The collection cylinder 3 is sleeved around the pump body. Before adjusting the position of the surrounding half-ring 41, the sealing cover 44 is placed on the top of the pump body. Then, the surrounding half-ring 41 is placed on the support plate 451. The position of the second mounting seat 46 on the bracket 48 is adjusted so that the inner wall of the surrounding half-ring 41 is close to the collection cylinder 3. The lifting drive 453 is started, and the lifting drive 453 drives the support plate 451 to rise.
