Abstract
Provided is a high-precision headstock for a deep hole drilling and boring machine. The high-precision headstock mainly solves the problems that an existing drilling and boring machine is poor in rigidity and low in shock-proof capability and processing precision. The high-precision headstock is characterized in that the headstock (1) is slidably connected to the left end of a lathe bed, an input shaft (2) of the headstock (1) is in straight connection with a motor shaft and is connected with a spindle (3) through a transmission shaft and a gear, the input shaft (2) and the transmission shaft are connected to the headstock (1) through rolling bearings, the spindle (3) is in centering connection with the headstock (1) through a radial clearance biserial short cylindrical roller bearing (4) in the radial direction, and the spindle (3) is axially connected to the headstock (1) through a large-bearing thrust roller bearing (5), and preload is axially added through a screw and a push ring. The high-precision headstock for the deep hole drilling and boring machine has the advantages of being high in rigidity, shock-proof capability and processing precision.
Description
Technical field
The utility model relates to a kind of headstock of lathe, especially the high-precision headstock of deep hole drilling and boring machine.
Background technology
In field of machining, boring boring machine is the visual plant of machining hole.The headstock that bores boring machine rises and drives the workpiece gyroscopic action.And there is poor rigidity in the existing headstock that bores boring machine owing to reasons in structure, and vibration resistance is low, and therefore the problem that noise is high and machining accuracy is low affects processing cost and efficient.
Summary of the invention
In order to solve the existing boring machine poor rigidity that bores, vibration resistance is low, the problem that noise is high and machining accuracy is low.The utility model provides a kind of deep hole drilling and boring machine high-precision headstock.It is strong that the high-precision headstock of this deep hole drilling and boring machine has rigidity, and vibration resistance is high, the characteristics that noise is low and machining accuracy is high.
The technical solution of the utility model is: the high-precision headstock of this deep hole drilling and boring machine comprises lathe bed, headstock, power shaft and main shaft.Headstock is slidingly connected on the lathe bed left end, the power shaft of headstock and motor shaft are direct-connected to be connect, power shaft is connected with main shaft with gear by power transmission shaft, power shaft and power transmission shaft are connected on the headstock by rolling bearing, main shaft diameter is to being connected on the headstock by the centering of radial clearance double row cylindrical roller bearing, main shaft axially is connected on the headstock by large carrying thrust roller bearing, and axially is added with preload by screw and throw-out collar.
The utlity model has following beneficial effect: the high-precision headstock of this deep hole drilling and boring machine is owing to adopting headstock to be slidingly connected on the lathe bed left end, the power shaft of headstock and motor shaft are direct-connected to be connect, power shaft is connected with main shaft with gear by power transmission shaft, power shaft and power transmission shaft are connected on the headstock by rolling bearing, main shaft diameter is to being connected on the headstock by the centering of radial clearance double row cylindrical roller bearing, main shaft axially is connected on the headstock by large carrying thrust roller bearing, and axially is added with the structure of preload by screw and throw-out collar.Improve rigidity, strengthen vibration resistance, reduce noise and improve machining accuracy.To have rigidity strong for the high-precision headstock of this deep hole drilling and boring machine thus, and vibration resistance is high, the characteristics that noise is low and machining accuracy is high.
Description of drawings
Accompanying drawing 1 is that the utility model headstock launches cutaway view.
1-headstock among the figure, 2-power shaft, 3-main shaft, 4-radial clearance double row cylindrical roller bearing, the large carrying thrust roller bearing of 5-.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Shown in accompanying drawing, the high-precision headstock of this deep hole drilling and boring machine comprises headstock 1, power shaft 2 and main shaft 3.Headstock 1 is the casing of sealing, symmetrical structure is adopted in the casing of headstock 1 and lathe bed junction, supplied with through separator by grease pump in the headstock 1, electrical interlocks is not so that before starting grease pump, motor can not start, headstock 1 is slidingly connected on the guide rail left end of lathe bed, the power shaft 2 of headstock 1 connects with motor shaft is direct-connected, motor is fixed on the base, base separates with headstock 1 base, power shaft 2 is connected with main shaft 3 with gear by secondary drive shaft, all gears all adopt high-quality mild steel, gear-grinding process processing after quenching, power shaft 2 and power transmission shaft are connected on the headstock 1 by rolling bearing, improve rotating accuracy by rolling bearing, be easy to safeguard, main shaft 3 radially is connected on the headstock 1 by 4 centering of radial clearance double row cylindrical roller bearing, main shaft 3 axially is connected on the headstock 1 by large carrying thrust roller bearing 5, and axially be added with preload by screw and throw-out collar, improve rotating accuracy and sound rigidity by radial clearance double row cylindrical roller bearing 4 and large carrying thrust roller bearing 5.
