The overall layout of the device
2. The grinding wheel of the grinding wheel holder is cooled by an independent cooling system with a coolant nozzle on each grinding wheel and an independent cooling water tank at one end of the device.
3. At one end of the grinder bed, there is an independent lubrication control tank. The lubrication system continuously lubricates the guide rail moving on the table.
(2) The main mechanical structure characteristics of the grinder
Note: 1. Grey cast iron with good strength, wear resistance and heat resistance and good vibration damping performance is used in the main structure. The interior is reasonably wired to enhance the rigidity. X axis (table) with hydraulic drive for reciprocating movement; Y-axis (front and rear direction) adopts the support plate and the ball screw for reciprocating movement; The Z-axis (grinding head) drives the precision C3 ball screw through the wheel for reciprocating movement to ensure the accuracy of the feed;
(3) guide way form
Note: Using a "V" and a "flat" iron-plastic guide rail;
(4) Grinding wheel frame structure
Note: the grinding wheel frame adopts double-layer fabric to ensure its rigidity; The downward movement of the grinding head adopts skateboard structure, which can avoid inaccurate feed due to long working life;
(5) The electrical system of the whole machine is controlled by multiple electrical groups. And the following points:
1 >, safety protection (mechanical interlock) refers to the interlock between the upper and lower feed and the grinding wheel rotation, only when the grinding wheel rotation can feed, can effectively prevent unnecessary losses caused by human operation;
2 >,( 68495847,circuit) overload means that the circuit exceeds the full load value without fault;
3 > Emergency stop refers to the operation that needs to be stopped in a certain emergency situation;
4 >, the machine completed in line with GB5226.1-2002/IEC60204-1:2000 mechanical safety mechanical electrical equipment.
(1) Good waterproof performance:
A: All the wall panels are installed, the cutting fluid and water flow are not above the main engine seat during work, and there is no water in the front and rear screw and the plane main engine seat on the main engine platform.
B. The left and right sides of the workbench are fully sealed. It effectively solves the problem that the two working guides are exposed to the outside when the workbench moves around in the daily, and it is easy to enter dirt and dust between the slide frame guide rail and the workbench guide rail. At present, only we use sealing measures.
C. The upper frame is fully sealed: the overall structure of the upper frame of the surface grinder is fully sealed, except that the spindle motor is exposed (heat dissipation). The rest of the upper frame is not exposed anywhere.
(2) Lubricating oil circuit:
A, the lubricating oil road is very hidden, and domestic and foreign counterparts, the lubricating oil pipe is very exposed above the host seat, resulting in a small amount of cutting fluid and copper corrosion for a long time, will also cause the workpiece to hit the copper pipe. Will cause the guide rail oil loss and oil shortage finally make the machine guide rail strain and overhaul, only our grinder in the lubricating oil road design to solve this hidden danger, all copper pipes are very hidden, from corrosion prevention to easy to comprehensively solve this hidden danger.
B, the grinder lubricating oil built-in → fundamentally solve the problem of not wasting lubricating oil, so that the lubricating oil can be recycled, and in the absence of lubricating oil around the workbench movement automatically stop and can not start the workbench movement oil pipe, after the lubricating oil is added, everything is normal. Although other domestic and foreign counterparts have lubricating oil built-in but no large wall panel will cause the cutting fluid to flow into the host and mix with the lubricating oil, affecting the
Grinding Machine performance.
C, fully sealed protection resulting in no debris and dust mixed with lubricating oil and ensure that the lubricating oil is clean, can be recycled, lubricating oil because the upper frame is fully sealed, the workbench seal and then complete the large wall panel, and then through the internal butt of the machine tool, from the ideal built-in design, to the use of unprecedented perfect internal lubrication can be assured to use, at present only my company's design structure There is a full range of complete internal lubrication.
(3) Our company relies on the advantages of mature flat grinding technology, the overall structure of the grinder adopts the design concept of fixed grinding head, saddle-type bed, and repeated movement of the table around and before and after.
