Description
Technical field
The invention belongs to vertical lathe technical field, relate to a kind of device that makes knife rest stable elevation, specifically a kind of balancing cylinder device of vertical lathe.
Background technology
In vertical lathe, balancing cylinder structure is a kind of cylinder structure of extensive use the most, and the precision of this structure cutter setting frame lifting has a great impact, so that have influence on the precision of workpiece processing.In prior art, the scheme that single-column lathe balancing cylinder structure adopts is to utilize support that ram is connected with piston rod, allows piston rod move together with ram, and piston rod is in the central effect of having played auxiliary ram lifting.But in this structure, because ram is long, so piston rod is also long accordingly, this has just brought relatively large error to piston rod.Piston rod is longer, and processing is got up also just inconvenient, and manufacturing tolerance is also just larger, and more easily fractures.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of balancing cylinder device of simple in structure, ingenious, rational vertical lathe is provided, this cylinder apparatus has effectively overcome in existing product that piston rod length is longer, the problem such as precision is not high.
According to technical scheme provided by the invention: a kind of balancing cylinder device of vertical lathe, be characterised in that: comprise the second piston rod, described the second piston rod bottom thread is connected with piston bush, oil cylinder cover is sheathed on piston bush outer circumference surface, described oil cylinder cover bottom thread is connected with top cover, oil cylinder set upper side head is installed with nut, cylinder flange dish is bolted on oil cylinder cover front end face, and the second piston rod outer circumference surface fits on cylinder flange dish inwall, described the second piston rod cavity upper end is provided with one section of boss, first piston bar is arranged in the second piston rod cavity, and the outer circumference surface of first piston bar fits in boss inner wall surface, first piston bar upper end is welded to connect plug, first piston bar bottom outer circumference surface is provided with annular projection, described annular projection matches with boss.
As a further improvement on the present invention, in the inner chamber of the described piston bush centre of gyration, by bottom capping, have valve body, described bottom is bolted connection on the step surface of piston bush inner chamber.
As a further improvement on the present invention, described cylinder flange dish is welded to connect in oil cylinder and puts.
As a further improvement on the present invention, between the boss of described the second piston rod and the outer surface of first piston bar, between piston bush and oil cylinder cover, between cylinder flange dish and the second piston rod outer surface, be equipped with sealing ring.
Compared with prior art, advantage is in the present invention: in the present invention, adopt two-stage piston rod construction, design ingenious, reasonable idea; Because the length of piston rod diminishes, piston rod is more easily processed, and reduced the error of processing aspect, guarantee the crudy of piston rod member, piston rod is deposited conveniently simultaneously, in transportation, handling process, is not easy to occur the phenomenon that the body of rod fractures.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Figure 1, comprise first piston bar 1, the second piston rod 2, nut 3, cylinder flange dish 4, plug 5, oil cylinder cover 6, piston bush 7, bottom 8, valve body 9, top cover 10, annular projection 11, boss 12 etc.
As shown in Figure 1, the balancing cylinder device of a kind of vertical lathe of the present invention, comprise the second piston rod 2, described the second piston rod 2 bottom thread are connected with piston bush 7, and oil cylinder cover 6 is sheathed on piston bush 7 outer circumference surfaces, and described oil cylinder overlaps 6 bottom thread and is connected with top cover 10, in order to reach more firm connection effect, preferably top cover 10 welds with electric welding with the junction of oil cylinder cover 6 again again, so both reaches the object of firm balancing cylinder, has also guaranteed the sealing of balancing cylinder.Oil cylinder overlaps 6 upper end heads and is installed with nut 3, cylinder flange dish 4 is bolted in oil cylinder and overlaps on 6 front end faces, and the second piston rod 2 outer circumference surfaces fit on cylinder flange dish 4 inwalls, described the second piston rod 2 inner chamber upper ends are provided with one section of boss 12, first piston bar 1 is arranged in the second piston rod 2 inner chambers, and the outer circumference surface of first piston bar 1 fits in boss 12 inner wall surface, first piston bar 1 upper end is welded to connect plug 5, first piston bar 1 bottom outer circumference surface is provided with annular projection 11, and described annular projection 11 matches with boss 12.
In the inner chamber of described piston bush 7 centres of gyration, by bottom 8 cappings, have valve body 9, described bottom 8 is bolted connection on the step surface of piston bush 7 inner chambers.
Described cylinder flange dish 4 is welded to connect on oil cylinder cover 6, makes more firmly safety of structure.
Between the boss 12 of described the second piston rod 2 and the outer surface of first piston bar 1, between piston bush 7 and oil cylinder cover 6, between cylinder flange dish 4 and the second piston rod 2 outer surfaces, be equipped with sealing ring, with the sealing of true capital preservation product higher level.
The course of work of the present invention is as follows: product of the present invention in use, by cylinder flange dish 4, this product is fixed on vertical lathe rotary slide base, recycling support makes ram be connected with plug 5, so that realize being synchronized with the movement of plug 5 and ram, when ram rises, first piston bar 1 is also and then synchronized with the movement together, when the height rising reaches with first piston bar 1 length when identical, the annular projection 11 of first piston bar 1 lower end is resisted against on boss 12, realize first piston bar 1 and drive the second piston rod 2 ascending motion together, apparatus of the present invention are easier than product of the prior art, process precision higher.
