Description
Technical field
Cover and the mounting technique of lathe are drawn the utility model relates to numerically-controlled machine tool, specially a kind of pulley assembly and using should
The numerically-controlled machine tool of pulley blocks draws cover.
Background technique
In recent years, as the manufacturing working ability of national mechanized equipment is substantially improved, also with people to environment, processing
Quality, processing efficiency, personal safety and the requirement of health are higher and higher, and numerically-controlled machine tool undoubtedly becomes most manufacturing enterprise
Preferred process equipment.In conjunction with the numerically-controlled machine tool of my company, there are four cover is drawn on every numerical control lathe, it is mutual to pass through strip of paper used for sealing between any two
Expansion fit, under the drive of machine tool table, even running is on guide rail, for stopping cutting fluid and iron filings.
New purchase numerically-controlled machine tool draws cover also even running at work, can spend several years with the aging of equipment, draw asking for cover
Topic also increasingly displays, and is mainly shown as：
1. cover is drawn to be combined with three groups of pulley blocks with guide rail below, pulley yoke lathe first wife in a thickness of 3mm,
The entire weight for drawing cover is all on three groups of pulley blocks, as the use of equipment and aging, pulley yoke are just deformed, thus shadow
The running precision of pulley blocks is rung, and then the running precision of cover is entirely drawn in related influence.The tradition for drawing cover to use as shown in figure 11 is sliding
Wheel group.
2. cause when serious draw cover between be separated from each other two-by-two, pulley is just detached from guide rail, only by draw cover upper end hook and
Lathe is connected, and since drawing cover is driven by workbench, draws cover impacted, workbench cannot be run, and otherwise drawn and covered just very
It is easy to be damaged.
3. pulley blocks are welded on drawing cover, once the pulley yoke of pulley blocks damages, it must just cut away and weld again
New pulley yoke, replacement are inconvenient.
4. not being adjustable the height of idler wheel due to being welded, it is not easy to adjust contact journey of the pulley with machine tool guideway
Degree.
If 5. without using cover is drawn, iron filings and cutting fluid splashes when work are easily damaged leading for numerically-controlled machine tool
Rail.
