An object of the utility model is to provide a take swivel work head, vice workstation and encoder's machining center workstation that independently comes out with machining center.

In order to achieve the above purpose, the technical scheme of the utility model is that:

a free standing machining center table comprising: base, vice workstation, rotatory polygon workstation, workstation transmission shaft, encoder, motor output shaft, servo motor, speed reducer and bearing, the workstation is equipped with rotatory polygon workstation at the top of base, vice workstation is equipped with respectively on the both sides of rotatory polygon workstation, servo motor is equipped with to the bottom in the base, servo motor's output shaft is connected with the speed reducer, the bearing frame is equipped with to the output end department of speed reducer, the bearing is equipped with on the bearing frame, two revolving stage locking hydro-cylinders are equipped with to the symmetry on the bearing frame simultaneously, the encoder is equipped with to the upper end of bearing, the encoder is connected with the workstation transmission shaft of dress in the middle of rotatory polygon workstation.

The encoder installed in the worktable can perform indexing operation of 0-360 degrees on the rotation angle of the rotary polygon worktable.

And a rotary table locking oil cylinder arranged on the bearing seat in the workbench is connected with a hydraulic control unit of the machining center through an oil pipe.

Compared with the prior art, the utility model, its positive effect does:

1. the worktable and the machining center are designed in a split mode, so that the weight of a lathe bed of the machining center is greatly reduced, the worktable is beneficial to bearing of the lathe bed of the machining center, and the service life of the machining center is prolonged;

2. when the workbench is used for machining, the rotating angle of the rotating workbench is indexed through the encoder, and the rotary table is suitable for machining at any rotating angle;

3. when the workbench is used for machining, the machining precision is very high, and five surfaces of a workpiece can be machined;

4. when the workbench works, a workpiece is clamped fast, the machining speed is high, and the indexing speed is twice as high as that of the conventional workbench;

5. the machining center worktable has the characteristics of one-time clamping, multi-process machining, powerful cutting, good precision, high efficiency, low use cost and the like.

Detailed Description

The technical solution of the present invention will be further described clearly and completely with reference to the accompanying drawings.

Referring to the attached drawings 1-4, the rotary polygonal workbench 3 is mounted at the top of a base 1 of the workbench, auxiliary workbenches 2 are mounted on two sides of the rotary polygonal workbench 3 respectively, a servo motor 7 is mounted at the bottom inside the base 1, an output shaft 6 of the servo motor 7 is connected with a speed reducer 8, a bearing seat 11 is mounted at the output end of the speed reducer 8, a bearing 9 is mounted on the bearing seat 11, rotary table locking oil cylinders 10 are symmetrically mounted on the bearing seat 11, an encoder 5 is mounted at the upper end of the bearing 9, and the encoder 5 is connected with a workbench transmission shaft 4 mounted in the middle of the rotary polygonal workbench 3.

The encoder 5 installed in the table can perform indexing operation of 0-360 degrees on the rotation angle of the rotary polygon table 3.

And a rotary table locking oil cylinder 10 arranged on a bearing seat 11 in the workbench is connected with a hydraulic control unit of a machining center through an oil pipe.

Before the workpiece is machined, the workpiece is clamped and leveled on the rotary polygonal workbench 3, machining data and machining parameters are input into a control unit of a machining center according to process requirements on a drawing, and the control center inputs the indexing requirements of the workpiece into an encoder 5. When the machining is carried out, the servo motor 7 arranged in the base 1 starts to work after receiving an instruction sent by the control center, the motor output shaft 6 of the servo motor 7 drives the speed reducer 8 to work, the transmission shaft of the speed reducer 8 drives the bearing 9 arranged on the bearing seat 11 and the encoder 5 arranged on the bearing 9 to rotate, the encoder 5 drives the rotary polygonal workbench 3 through the workbench transmission shaft 4 to carry out indexing rotation on the rotary polygonal workbench 3 and a workpiece according to the index value of the rotation angle set by the encoder 5, and the machining center carries out machining operation on the workpiece on the rotary polygonal workbench 3 at the moment. When the rotary polygonal working table 3 does not need to be rotated, the hydraulic driving unit of the machining center drives two rotary table locking cylinders 10 mounted on bearing blocks 11 to lock the rotary polygonal working table 3. When the auxiliary worktable 2 is not needed for processing the workpiece, the auxiliary worktable 2 can be detached from the rotary polygonal worktable 3 before processing the workpiece, and the auxiliary worktable 2 can be installed again when needed.
