Description
Technical field
The utility model belongs to lathe-techniques field, specifically, and particularly a kind of lathe pressing tailstock automatic adjusting mechanism.
Background technology
The pressing tailstock of lathe is generally made up of parts such as top and tailstock bodies, is toply connected with tailstock body by screw pair, and tailstock body is slidably mounted on lathe bed.When needs top tight workpiece, operating personnel's hand push tailstock body, makes pressing tailstock elder generation Long Distances on lathe bed move, when top close workpiece, tailstock body is locked on lathe bed, then shakes top driving handwheel, make toply to stretch out tailstock body, until by workpiece pre-tightening.Above process not only complex operation, wastes time and energy, and can affect the efficiency of processing, and the top pretightning force to workpiece applying is uncontrollable, not identical to the pretightning force of each workpiece during batch production, easily affect the uniformity of converted products, even can bending workpiece time serious.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of lathe pressing tailstock automatic adjusting mechanism that pretightning force is consistent of can guaranteeing.
The technical solution of the utility model is as follows: a kind of lathe pressing tailstock automatic adjusting mechanism, lathe bed (1) arranges tailstock body (2), the upper end of this tailstock body (2) is provided with top (3), its key is: described top (3) and tailstock body (2) fix, two line slideways be parallel to each other (4) are provided with in the below of tailstock body (2), this line slideway (4) is fixed on the end face of lathe bed (1), and the bottom of tailstock body (2) is slidably matched with two line slideways (4) respectively by two groups of slide blocks (5); Drive lead screw (6) is provided with between two line slideways (4), one of this drive lead screw (6) is connected by the output shaft of shaft coupling with servomotor (7), is fixed on the bottom of tailstock body (2) with the nut seat (8) of this drive lead screw (6) threaded engagement; Induction nail (9) is also housed in the bottom of described tailstock body (2); following closely three proximity switches (9) matched with this induction is arranged on location-plate (10); proximity switch near servomotor (7) is protection proximity switch (11); proximity switch away from servomotor (7) is zero proximity switch (13), and a middle proximity switch is conversion proximity switch (12).
Adopt above technical scheme, servomotor operates, and the output shaft of servomotor drives drive lead screw to rotate, and makes tailstock body moving linearly under the guiding of line slideway.Tailstock body is offered from original position and is done Long Distances rapid movement, when moving to the position of induction nail corresponding conversion proximity switch, being switched by control system, making tailstock body do short stroke motion at a slow speed, until top by workpiece pre-tightening.Zero proximity switch is followed closely with induction and is coordinated, and the position of each return of tailstock body can be made to be consistent; Protection proximity switch is followed closely with induction and is coordinated, and guarantees that the position of each top tight workpiece of tailstock body is consistent.As can be seen here, the utility model whole process is controlled automatically by electric-control system, and manipulation is simple, convenient, time saving and energy saving, greatly can improve working (machining) efficiency; , top the pretightning force that workpiece applies accurately to be controlled by electric-control system meanwhile, and the size of moment can be changed as required, effective so identical to the pretightning force of each workpiece when ensure that batch production, meet the needs of homogeneity of product processing.
In order to simplify structure, convenient for assembly, described servomotor (7) is installed on bearing (14), this bearing (14) and lathe bed (1) fix, one end of described drive lead screw (6) is supported mutually by bearing and bearing (14), the other end of drive lead screw (6) is supported mutually by bearing and positioning seat (15), and positioning seat (15) is fixed on lathe bed (1).
For the ease of adjusting position, with the needs of satisfied processing different workpieces, described location-plate (10) is elongated rectangular shape, and be bolted on lathe bed (1), location-plate (10) offers the rectangular groove (10a) of a row for proximity switch selection installation along its length wise.
Beneficial effect: the utility model can control tailstock body fast and full gear feeding automatically, and fast feed energy at a slow speed automatically switches, the size of tailstock body pretightning force is adjustable, identical to the pretightning force of each workpiece when can guarantee to produce in batches, there is structure simple, compact, connection and reasonable arrangement, the features such as assembling is easy, easy to operate, quick.
