Abstract

The utility model relates to an extending milling head for a machine tool, which belongs to the field of machine tools. The extending milling head is provided with a milling head box, and is characterized in that a spindle is mounted in the milling head box, a spindle bearing is mounted at the front end of the spindle, a double-row cylinder roller bearing is installed at the rear end of the spindle, a positioning taper sleeve is mounted at the upper end of the spindle, a broach device is mounted in the spindle, a blind rivet is arranged at the upper end of the broach device, a standard pulling claw is mounted at the lower end of the broach device, a disk spring is installed in the broach device, a connector is connected with the spindle via an involute spline pair, and a connecting blind rivet is mounted at the upper end of the milling head box. The extending milling head is strong in rigidity, high in processing precision and large in transmission torque, is an independent component relative to the total machine tool, and is convenient to be assembled and maintained. Broach actions of the extending milling head are realized by broach actions of the spindle of the machine tool, automatic tool changing can be realized, and processing efficiency is increased. The extending milling head is applicable to general tools, thereby reducing cost and meeting requirements of customers better.

Description

Lathe is with extending milling head
Technical field
The utility model relates to machine tool field, especially a kind ofly is 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
The purpose of this utility model 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 utility model 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 beneficial effects of the utility model are, 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
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 structural representation of the present utility model.
1. blind rivets among the figure, 2. the location tapered sleeve 3. connects blind rivet, 4. connected body, 5. milling head casing, 6. Biserial cylindrical roller bearing, 7. main shaft, 8. broaching tool device, 9. standard pulling claw, 10. main shaft bearing.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, to help understanding content of the present utility model.
As shown in Figure 1, the main shaft 7 that the utility model will have the standard taper hole is installed in the milling head casing 5, main shaft 7 front ends are installed main shaft bearing 10, Biserial cylindrical roller bearing 6 is installed in main shaft 7 rear ends, this structure both can guarantee to extend the rigidity and the impact resistance of milling head, also can guarantee to extend the running accuracy and the machining accuracy of milling head, location tapered sleeve 2 is equipped with in main shaft 7 upper ends, guarantee to extend between milling head and the machine tool chief axis and have very high axiality, broaching tool device 8 is housed in main shaft 7, homemade blind rivet 1 is equipped with in the upper end of broaching tool device 8, standard pulling claw 9 is equipped with in the lower end, disk spring is equipped with in inside, after the extension milling head is installed to lathe, broaching tool device 8 actings in conjunction of being made up of hydraulic cylinder and disk spring of this milling head and machine tool chief axis inside can realize broaching tool and the loose cutter action synchronous with machine tool chief axis, the realization automatic tool changer, functions such as subsidiary cutter inner cooling.Connect by the involute spline pair between connected body 4 and the main shaft 7, milling head casing 5 upper ends are equipped with and connect blind rivet 3.
After the utility model location tapered sleeve 2 is aimed at the taper hole of machine tool chief axis, to extend milling head by connection blind rivet 3 is connected with ram, realize the action of loose cutter and broaching tool more together by blind rivet 1, broaching tool device 8 and standard pulling claw 9, the keyway of connected body 4 is connected the transmission moment of torsion with the key of machine tool chief axis, connect by the involute spline pair between connected body 4 and the main shaft 7, realize rotating with speed, universal cutter is changed in the taper hole of main shaft 7 and can process with machine tool chief axis.
