Abstract
The utility model relates to a directly-coupled accelerating power cutter holder for a turning center, belonging to the field of metal cutting and solving the problems of low acceleration rate and poorer rigidity of the exiting power cutter holder. The directly-coupled accelerating power cutter holder for the turning center is structurally characterized in that a shell is connected with a supporting base; a bracket is fixed on a bearing in the shell; an input shaft is fixed on the bearing in the supporting base; a sun gear shaft is connected with the input shaft; an inner gear ring is fixed on the shell; a public planetary gear is meshed with the inner gear ring and connected with the bracket by a central shaft of a planet wheel; an elastic sleeve is connected with the sun gear shaft; the end part of the shell is provided with an end cover; and a seal ring is arranged between the end cover and the sun gear shaft. By the improved internal structure of the cutter holder, a transmission system of the planetary gear is utilized to meet the acceleration demand, so that the directly-coupled accelerating power cutter holder leads the advantages: small volume, compact structure, light weight and good rigidity of the transmission system of the planetary gear to be carried on, realizes the output of all power cutter positions at different speed and different torque, and leads the turning center to meet processing requirements such as drilling, milling, tapping and the like of various working conditions, thus realizing high-speed cutting function.
Description
Technical field
The invention is to the improvement of turning center with the direct-connection type speeding-up dynamic tool apron structure, relates to the metal cutting field.
Background technology
Lathe is the visual plant of field of machining, the appearance of Digit Control Machine Tool is the major transformation of machine industry, numerically controlled lathe is as a class of Digit Control Machine Tool, constantly develops towards high-speed, high accuracy, direction multi-functional, intensification, and turning center develops thus just and comes.Turning center can also the processing plane cam, polygon, the face of cylinder, end face index hole, groove and screw thread etc. except can carrying out conventional turning processing.It can finish whole set of process under clamping of workpiece, save operation transfer time, avoid the multiple clamping error, enhances productivity and machining accuracy.Use turning center to carry out conventional turning processing and can select universal cutter, hole, process such as tapping, milling then need to adopt the power cutter that self has the independent power source.Under different operating modes, the rotating speed and the moment of torsion of power cutter had different requirements, but the rotating speed and the moment of torsion relative fixed of the power cutter tower line shaft itself that turning center is equipped with for this reason, need to be provided with speed adjusting gear in the dynamic tool apron of clamping cutter.The present domestic turning center dynamic tool apron supply that still do not have, external product then mostly is constant speed or deceleration tool rest, and speedup dynamic tool apron product is less.Be difficult to the speed increasing ratio that provides bigger and adopt the speedup dynamic tool apron of conventional gears transmission owing to be subjected to the restriction of gear size, and rigidity is relatively poor.
Summary of the invention
In order to solve the problem of above-mentioned existence, the invention provides a kind of can provide that high speed increasing ratio, volume are little, in light weight, the turning center of good rigidity is with the straight dynamic tool apron of direct-connection type speeding-up.
The purpose of the invention is achieved through the following technical solutions: a kind of turning center direct-connection type speeding-up dynamic tool apron, housing is connected with base for supporting, support is fixed on the interior bearing of housing, power shaft is fixed on the interior bearing of base for supporting, sun gear shaft is connected with power shaft, ring gear is fixed on the housing, public planetary gear and ring gear engagement, public planetary gear is connected by the planetary gear central shaft with support, resilient sleeve is connected with sun gear shaft, shell end is provided with end cap, is provided with sealing ring between end cap and the sun gear shaft.
The adjustment packing ring is housed between ring gear and the base for supporting.
Between power shaft and sun gear shaft, adopt ball bearing to support.
The beneficial effect of the invention: said structure is adopted in the invention, turning center external torque that power knife rest provides is passed through the input of planetary wheel carrier power shaft, ring gear is fixed in the tool rest housing, public planetary gear is with power shaft and the planetary wheel carrier that an is configured to revolution and the rotation with the ring gear engagement, the drive sun gear shaft rotates, and at last moment of torsion is passed to the cutter output that utilizes resilient sleeve to be attached thereto to connect by sun gear shaft.The invention is applied to turning center speedup dynamic tool apron with planet circular system, inherited that planet circular system transmission mechanism volume is little, the advantage of compact conformation, in light weight, good rigidly, realized the output of turning center each power cutter spacing friction speed, different moments of torsion, make turning center satisfy processing requests such as drilling under the various operating modes, milling, tapping, realize the high-speed cutting function.
Possess the tooth form and the cooling nozzle that meet the DIN69880 standard interface on the base for supporting of dynamic tool apron, play the effect of stationary power tool rest and cooling cutter.Because tool rest is in machining area, tool rest front end employing high speed rotating seal ring seals and satisfies the high-speed cutting requirement.
