Stone machinery products to ensure the quality of the assembly must be in accordance with the provisions of all kinds of stone machinery products technical requirements to operate the assembly. Assembly of the different technical requirements of stone machinery products, though not the same, but there are many in the assembly process must abide by the main points of the contract.
1, do a good job cleaning and cleaning parts. Clean-up including the removal of residual casting sand, rust, chips and so on. In particular, some important parts, such as large gantry cutting machine, the cavity should be coated with rust. The part of oil, rust or chip can be attached to the diesel, kerosene or gasoline to clean a washing liquid, and then use compressed air.
2, matching the surface or in connection with the former, generally need to add lubricant. In particular parts of the bearing spindle box parts, elevator parts of the screw nut.
3, matched with the size of parts to be accurate, with the size of the assembly or re-examination should be carried out sampling. For example: the journal and bearing spindle with the site, with the headstock and the bearing hole and the center distance.
4, wheel assembly, requiring co-axle center line of two teeth to be in the same plane and parallel to each other, the tooth should be combined to ensure a normal gap, while the axial displacement �� 2MM.
5, the connection should check whether the combination of flat surfaces, with or without distortion, or should be finishing, burr, to ensure close contact joints, flat, not skewed.
6, seals should be pressed into the seal groove parallel, not twisted, broken scratching the sealing surface.
7, the pulley assembly requirements must be parallel to the axis of the two pulleys, round groove center should be positive, offset over the General Assembly so that the tension pulley uneven and accelerated wear caused by belt slippage. V-belt assembly before the same time matching, the length should be consistent, to prevent vibration transmission occurred.
8, the bearing assembly should be cleaned before, washed rust before assembly; cleaning should pay attention to check whether the raceway and rolling rust, rotation is flexible; bearing assembly should be in line with the surface coating layer of lubricant, assembly found that much difference when the pressure should be checked to stop the assembly; bearing assembly, no model should be towards the end, the direction by the shoulder; set when the afterburner bearing size, direction, location should be appropriate, it should not roller rolling force, should be symmetrical beating, not hit, to ensure that end with the axis perpendicular to prevent the installation of tilt.
9, threaded locking device should be used, according to the actual situation and the design requirements of the following commonly used locking device; double-locking nut; spring locking washer; cotter pin locking; washers with locking nuts and flowers round pad locking ; symmetric multiple bolt tightening method should be symmetrical in order to gradually tighten, strip joints symmetrically in two directions from the middle to gradually tighten. Bolted rear rib nut should be highlighted.
10, so check the side of the assembly side.
11, do a good job driving prior inspection. For example: Check the integrity of the assembly, the connecting part of the accuracy and reliability, the flexibility of moving parts movement, the lubrication system normal and so on.
12, do a good job of monitoring the work of the boot process. Start the machine immediately after the main working parameters and observe the moving parts are normal movement. Main operating parameters including the speed, smoothness of movement, spindle rotation situation, oil pressure and temperature, vibration and noise. Only when the start-up phase of the movement indicators of normal, stable, and can be test run.
13, all kinds of stone machinery products according to the conditions of acceptance trials, testing the project. For example: take the cutting speed and stroke adjustment and testing of movement at a stroke adjustment, spindle rotation accuracy testing
