Embodiment 1

[0024] Among them, the elastic direct-connected water mill consists of a grinding disc, a grinding block mounted on the bottom surface of the grinding disc, a body, a walking mechanism and a handrail mounted on the body, a combined switch mounted on the handrail, a water supply system and a power transmission system. The motor shaft of the power transmission system is vertically supported on the angular contact ball bearing, and the lower end of the motor shaft is directly connected with the direct-connection ball head, and the head of the direct-connection ball head is inserted into the pit on the grinding disc. The motor torque is directly transmitted to the direct-connected ball head through the motor shaft, and then transmitted to the grinding disc connected to the equal-torque coupling disc through the flexible equal-torque coupling disc connected with the direct-connecting ball head, so that the grinding disc rotates. Thereby driving the grinding block on the bottom surfa...

Embodiment 2

[0026] A surface grinding process based on an elastic direct-connection water mill, comprising the following steps:

[0027] (1) Soaking, soak the mechanical parts with 8%-26% hydrochloric acid to remove surface rust and dirt, then soak in clean water, change the water at least once, and dry the mechanical parts for later use;

[0028] (2) Coarse grinding, using a martensitic stainless steel high-strength grinding wheel with a steel wire diameter of 0.3-0.5mm and a hardness of HRC350 to perform rough grinding on the surface of the mechanical parts to be processed. The grinding line speed of the grinding wheel is 25-40m / s, and the surface removal depth is 200-300 , During the cleaning process, it is necessary to swing the grinding wheel quickly and ensure that the contact pressure between the grinding wheel and the surface of the pump body is as small as possible to prevent the surface of the pump body from overheating and crack defects, which will affect the surface quality;

Embodiment 3

[0034] (1) Soaking: soak the mechanical parts in a special solution for 25-35 minutes;

[0035] (2) Coarse grinding: Take out the soaked mechanical parts and dry them with cotton cloth, and then use 100# dry sanding paper for grinding;

[0036] (3) Fine grinding: wash off the grinding debris attached to the surface of the mechanical parts after rough grinding with water, then dry the mechanical parts, and use 800# water grinding paper to polish the mechanical parts;

[0037] (4) Water mill: place the finely ground mechanical parts under the faucet, and polish the mechanical parts with 1000# water grinding paper until the surface of the mechanical parts is smooth and flat;

[0038] (5) Drying treatment: Rinse the mechanical parts after water milling with water again, and then directly dry them with a hair dryer.

Abstract

The invention discloses a surface grinding process based on an elastic direct-connected water mill. The steps of the processing process are soaking, rough grinding, water grinding, fine grinding, rinsing and drying. After detailed grinding through these steps, mechanical parts can be The surface is polished smoothly to reduce the situation that the rough surface does not meet the tooling requirements. The invention can reduce the roughness of the outer surface of the mechanical parts; it can also remove excess impurities produced by welding during the manufacturing process of the mechanical parts, making the mechanical parts more beautiful, and at the same time improving the precision of the mechanical parts; it also enables the grinding of the mechanical parts The workmanship is more perfect.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a surface grinding process based on an elastic direct-connected water mill. Background technique [0002] There are more or less burrs, barbs, etc. on the outer surface of the parts processed by the existing mechanical processing equipment. For these defects, there is currently no special equipment to deal with them. Generally, they are manually used with more common tools (such as Scissors, sand paper, etc.) for trimming, time-consuming and labor-intensive, for tubular parts, the burrs on the inner tube wall are difficult to remove manually. [0003] The size requirements of mechanical parts are quite strict, and the traditional butt joint assembly method has low precision and cannot meet this requirement; and due to manual measurement and manual welding, there will be problems such as misoperation and inaccurate measurement, resulting in low precision of mechanical parts A...
