The present invention is a turret tool stand of a lathe, in particular, a plurality of turrets are installed, and each turret can rotate randomly at various angles, and relates to a 360 degree automatic random power servo turret tool stand performing full cutting operations. .

The lathe is a multifunctional precision machine, which is equipped with various cutting tools such as lathe cutter, milling cutter, drill, and screw tap in the turret according to the needs and purposes in the working area of the machine. Control the feedback and complete the cutting operation.

Due to the necessity of processing the workpiece with multiple tools in the machining process, the cutting tool is continuously changed in the turret to perform the cutting operation. Therefore, it has been developed to directly drive the rotating turret tool post using a kind of motor. A turret equipped with a plurality of sets of tools is installed at the periphery of the turret tool stand, and after one of the tools finishes processing the workpiece, the operator controls the motor to drive the turret tool stand to rotate to a predetermined position. At the same time, the turret equipped with another tool is transferred to the machining position and continues to be processed.

The motor-driven turret tool stand can of course be replaced with tools as needed and improves the machining efficiency. However, since the turret is fixed to the turret tool stand, the turret is driven when the motor drives and rotates the turret tool rest. Since the self-rotation is impossible when moving to a predetermined position along the tool post, the tool mounted on the turret has a cutting work limitation only in the axial direction of the turret tool post. In other words, the cutting range of the tool is limited to a single direction, and full operation is impossible, which greatly reduces the practicality and convenience of the machine.

Therefore, once the turret is connected to the periphery center of the turret tool stand, and the rotary mechanism is installed and the turret is driven simultaneously while the turret tool stand rotates, the work range is extended and the tool of the lathe has the maximum work efficiency. The invention was completed to complete the present invention.

Accordingly, the present invention is a conventional motor-driven turret is fixed to the turret tool stand to move to a predetermined position along the turret tool stand during processing, but the turret itself is not possible to turn the cutting range of the tool is limited In order to improve the problem that the work efficiency of the work is reduced, that is, the present invention provides a kind of 360 degree automatic random swing servo motor turret so that the turret in the work zone is randomly turned when the turret tool post is rotated to the work zone. By extending the working area and working method of the tool installed in the turret by positioning it to the required machining angle, the tool is able to perform a full cutting work to improve the practicality and convenience of the industrial manufacturing process. I put it.

The present invention to achieve the above object provides a kind of 360 degree automatic random swing power servo turret tool stand, which consists of a spindle, a turret tool stand, a turret set equipped with the necessary tools, a turret turning device and a tool rotating device It became. At least one turret is inserted at the periphery of the turret tool post, and various necessary tools are mounted inside the turret. Among them, the turret is inserted into the saddle hole drilled around the turret tool post, and the interlocking member and the rotating lever are installed in the turret.

The other end of the dribble gears is installed at the table center, and the dribble gear is mounted on the table and the fixed ring. At the same time, the dribble gear is installed in the weight in the saddle hole.

The turret rotates along the turret tool set to a predetermined work area, and then the servo motor of the turret turning device, the driving lever interlocked with the servo motor and penetrated into the turret tool post, the transmission gear interlocked with the driving lever, The transmission gear and the gear are driven in this order. Then, the gear is eccentrically engaged with one of the driving gears to drive the driving gears. The driving gear interlocks the interlocking members in the turret and also pivots the turret equipped with the necessary tools located in the work area. At the same time, the necessary tools drive the drive motor included in the tool rotating device, the gear train interlocked with the drive motor and the drive lever interlocked with the gear train in this order.

In addition, the drive lever is penetrated to the turret tool post, and interlocked with the umbrella gear, the umbrella gear is engaged with the operating gear interlocked with the tool to rotate the tool to perform cutting processing Let's do it. Therefore, the turret in the work area can be freely rotated 360 degrees according to the machining requirements, and also possible to operate a variety of angles, it is possible to perform a full cutting operation.

Next, a preferred embodiment of the present invention will be described in detail with reference to the drawings as follows, and the following description is only for more easily recognizing and understanding the embodiment of the present invention, and in what form for the present invention, Since it is not intended to limit the award, various modifications and changes can be made to the present invention under the same purpose as the present invention, and all such changes are included in the protection scope of the present invention.
