Description

Technical Field

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

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

[0003] In the process of processing the pump body of a marine vertical pump, drilling and grinding holes are key processes. Special fixtures are usually used during processing to ensure the stability and processing accuracy of the pump body. The fixture usually includes a base and a clamping device. The base is used to fix the pump body, usually with adjustable support blocks to accommodate pump bodies of different sizes. The clamping device can use hydraulic or mechanical clamping methods to firmly fix the pump body on the base to prevent movement during processing.

[0004] However, there is a potential problem in this process: debris may be deposited in the hole, and too much debris may accumulate on the workbench. When cleaning the debris, the operator may inhale tiny debris, which not only affects the processing accuracy, but also may cause greater stress when the drill or other processing tools come into contact with the pump body. Due to the accumulation of debris, the drill bit may encounter uneven resistance when entering or exiting the hole, resulting in increased friction between the processing tool and the pump body. This uneven stress distribution will cause the pump body to have an unstable stress state during the processing, which will cause the vertical pump to sway or shake. This shaking will not only affect the processing quality, but may also cause additional wear on the processing equipment, and even affect the performance and service life of the final product, and may also cause health risks to the operator.

A placement hole 11 is opened on the top of the workbench 1. The clamping assembly 2 is located on the workbench 1 near the placement hole 11. The clamping assembly 2 is used to fix one end of the pump body in the placement hole 11.

[0032] Reference Figure 2 and Figure 3The 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 arranged on the clamping blocks 211. The plurality of clamping blocks 211 are arranged at intervals along the circumferential direction of 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 with 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 and the clamping blocks 211 that are in contact with each other are both conical surfaces, so that when the locking ring 22 is rotated, as the locking ring 22 is rotated, the locking ring 22 is tightened. With the rotation of the ring 22, the locking ring 22 can rise or fall along the clamping block 211, and the clamping block 211 is also tensioned as the locking ring 22 rises and falls. In this embodiment, six clamping blocks 211 are provided, and the elastic rings 212 are all connected to the clamping blocks 211 through slots. The elastic rings 212 are rubber rings, and a first buffer block 213 is bonded to one 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.
