Abstract
The invention relates to a square ram structure turning tool holder. The problems that a transverse turning tool holder of an existing large-scale numerically controlled horizontal lathe is poor in rigidity and short in stroke are mainly solved. The square ram structure turning tool holder is characterized in that a ram (1) is a square ram, and the lower portion of the ram is matched with an aluminum alloy guide rail plate; the turning tool holder (2) is fixed to the front end of the upper portion of the ram (1); a grinding head (3) can further be fixed to the ram (1); the grinding head (3) is locked on a grinding head base (4) through a T-shaped slot bolt; the rear end of the ram (1) is connected with a transverse feeding mechanism (5) and lubricated through a lubricating system (7). The square ram structure turning tool holder has the characteristics of being good in rigidity and long in stroke, and feeding is accurate.
Description
Technical field
The present invention relates to mechanical field, is a kind of square ram structure tool holder specifically.
Background technology
In the structure of the horizontal tool holder of current large-sized numerical control horizontal lathe, due to guideway poor rigidity such as vertical cutter plates, make tool holder stroke shorter, can not meet the requirement of Long Distances, high rigidity, and feed accuracy is low, reduce crudy.
Summary of the invention
In order to overcome the short deficiency of existing large-sized numerical control horizontal lathe horizontal tool holder poor rigidity, stroke, the invention provides a kind of square ram structure tool holder, this square ram structure tool holder has good rigidly, feature that stroke is large, and feeding is accurate.
Technical scheme of the present invention is: a kind of square ram structure tool holder, comprise ram, tool holder, the described ram side of being ram, match with aluminum alloy guide rail plate in bottom, described tool holder is fixed on above ram front end, described ram can also fix bistrique, and bistrique passes through T-slot bolt-locking on head holder; Described ram rear end is connected with transverse feed mechanism, and is lubricated by lubricating system;
Described transverse feed mechanism comprises servomotor, ball-screw, tool-post structure, and described ball-screw two ends are fixed on ram by leading screw fore-stock and leading screw after-poppet; Described servo motor output shaft is connected with pinion, and pinion is meshed with gear wheel, and gear wheel is internally connected with ball screw, and described ball screw matches with ball-screw.
Described servomotor is fixed on electric machine support, and electric machine support is fixed on tool-post structure.
Described ball screw is externally connected to bearing inner sleeve, and bearing inner sleeve outside is provided with bearing, and Bearing outer is provided with bearing outside, and bearing outside is fixed on tool-post structure.
The present invention has following beneficial effect: owing to taking such scheme, and it is secondary that ram and aluminum alloy guide rail form ram gib, can increase tool holder stroke, thus meet the requirement of Long Distances, high rigidity.Transverse feed mechanism adopts ball-screw two ends to fix, screw rotational structure, and feeding, fast shifting movement drive ball screw assembly, to complete by AC servo motor through gear pair, and such feed accuracy is high, thus makes raising workpiece processing quality.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
By shown in Fig. 1 to Fig. 6, a kind of square ram structure tool holder, comprises ram 1, tool holder 2, described ram 1 side of being ram, matches with aluminum alloy guide rail plate in bottom, forms ram gib secondary.Described tool holder 2 is fixed on above ram 1 front end, after unloading tool holder 2, ram 1 can also fix bistrique 3, and bistrique 3 passes through T-slot bolt-locking on head holder 4, and bistrique 3 can around vertical axis revolving on head holder 4.The lubrication at the positions such as described ram 1 rear end is connected with transverse feed mechanism 5, and is lubricated by lubricating system 7, and lubricating system is arranged on the side of tool-post structure 8, and tool holder guideway, lead screw pair, leading screw bracket bearing are secondary is automatic ration lubrication.
Described transverse feed mechanism 5 comprises servomotor 6, ball-screw 15, tool-post structure 8, described ball-screw 15 two ends are fixed on leading screw fore-stock 9 and leading screw after-poppet 20 respectively by flat key, and leading screw fore-stock 9 and leading screw after-poppet 20 are separately fixed on ram 1.On described servomotor 6 output shaft, cover has expansion sleeve 17, and output shaft is connected with pinion 18, and pinion 18 is meshed with gear wheel 14, and gear wheel 14 is internally connected with ball screw 13, and described ball screw 13 matches with ball-screw 15.Described gear wheel 14 is enclosed within the outside of ball screw 13 one end, and the two is fixed by screws in together.Described ball screw 13 outside has been connected by screw bearing inner sleeve 12, and bearing inner sleeve 12 outside is provided with bearing 11, and bearing 11 outside is provided with bearing outside 10, and bearing outside 10 is fixed on tool-post structure 8, and such ball screw 13 can freely be rotated.Described servomotor 6 is fixed on electric machine support 19, and electric machine support 19 is fixed on tool-post structure 8.When visiting transverse feed mechanism work, servomotor 6 starts, gear wheel 14 is driven to rotate by pinion 18, gear wheel 14 drives ball screw 13 to rotate, because ball screw 13 lateral attitude is fixed, therefore ball screw 13 is rotated and ball-screw 15 can be driven to move forward and backward, thus drives ram 1 transverse shifting.
