Description
Technical field
The present invention relates generally to waterproof sealing field, refers to especially a kind of waterproof seal for cutting machine revolving table waterproof sealing and comprises the cutting machine of described waterproof seal.
Background technique
The effect of cutting machine is that device is divided into single circuit unit, the working mechanism of cutting machine is the heavy grinding that utilizes emery wheel blade, yet can produce a large amount of heat at cutting process medium plain emery wheel blade and processed device, too high temperature can have a strong impact on cut quality, and greatly shortens the working life of cutter.Temperature when controlling cutting process, need to carry out cooling with cooling water to operation interval.
Cutting machine X-axis driven rotary worktable is done to-and-fro motion at a high speed, needs to carry out waterproof sealing between revolving table and sectioned housing.If sealability is bad, cooling water will enter precision lead screw, the rail sections of X-axis worktable, and the long-time residual meeting of cooling water is got rusty the parts such as Workbench base, slide carriage, thereby the precision of destruction work platform affects cut quality; If aqueous vapor enters in the drive motor of revolving table, will motor damage, and also the direct driving motor of revolving table is more expensive, and electrical fault can not be processed in time and will make monoblock device all scrap, and causes more serious economic loss.Therefore the waterproof seal of revolving table has very important significance for cutting machine.
Existing seal arrangement mainly carries out encapsulation process by the mode of rubber seal, and the advantage of this structure is simple in structure, and cost is low.But because the processing conformity of nonmetallic material is poor, gap control is more difficult, gap tension causes rotation to have some setbacks, gap excessively pine causes waterproofing effect poor, long-term use can make rubber seal aging, so sealing effect is undesirable, still has water and remains in revolving table inside.
