Abstract
The invention relates to an extending milling head for a machine tool, belonging to the field of machine tools. A milling head box body is arranged. The extending milling head is characterized in that a main shaft is installed in the milling head box body, a bearing of the main shaft is installed at the front end of the main shaft, two columns of cylindrical roller bearings are installed at the back end of the main shaft, a locating taper sleeve is installed at the upper end of the main shaft, a broach device is installed in the main shaft, a blind rivet is installed at the upper end of the broach device, a standard pulling claw is installed at the lower end of the broach device, the inside of the broach device is provided with a disk spring, a connecting body and the main shaft are connected through an involute spline pair, and a connecting blind rivet is installed at the upper end of the milling head box body. The extending milling head has the advantages of strong rigidity, high processing precision and large transmission torque, and is convenient for assembling and maintaining relative to a whole machine which is an independent component; the broach operation of the extending milling head is realized through the broach operation of the main shaft of the machine tool; because a cutter can be changed automatically, the processing efficiency is improved; and because a universal cutting tool can be utilized on the extending milling head, the cost is reduced, and the customer requirement is better satisfied.
Description
Technical field
The present invention relates to machine tool field, especially a kind ofly be used for extension milling head large-scale, heavy plane milling and boring machine.
Background technology
As everyone knows: large-scale, heavy plane milling and boring machine is in the deep hole or step plane of some heavy parts of processing, vertical ram can't enter deep hole or interfere with the vertical plane on step plane, generally be to use the cutter of band lengthening knife bar, just can't guarantee crudy and machining accuracy but the length of knife bar is long.
Summary of the invention
Purpose of the present invention just is rigidity deficiency when solving band lengthening knife bar cutter deep hole processing or step plane, the problem of machining accuracy difference, provide a kind of lathe with extending milling head, to extend milling head by the casing that extends milling head is fixed on the machine ram, promptly universal cutter can be installed in and extend on the milling head, substitute band lengthening knife bar and process.
The present invention adopts following technical solution: a kind of lathe is with extending milling head, be provided with the milling head casing, it is characterized in that main shaft is installed in the milling head casing, front-end of spindle is installed main shaft bearing, rear-end of spindle is equipped with Biserial cylindrical roller bearing, the location tapered sleeve is equipped with in the main shaft upper end, the broaching tool device is housed in main shaft, blind rivet is equipped with in the upper end of broaching tool device, the standard pulling claw is equipped with in the lower end of broaching tool device, disk spring is equipped with in the inside of broaching tool device, connects by the involute spline pair between connected body and the main shaft, and milling head casing upper end is equipped with the connection blind rivet.
The invention has the beneficial effects as follows, this extension milling head rigidity is strong, the machining accuracy height, the transmission moment of torsion is big, with respect to complete machine is individual components, be convenient to I﹠ M, be particularly suitable for that the locus is less, the processing of the special workpiece of limited location, obform body part, the broaching tool action of extending milling head is that the broaching tool by machine tool chief axis moves and realizes, can carry out automatic tool changer, improve working (machining) efficiency, universal cutter can use at this extension milling head, thereby reduce cost, meet customer need better.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
