With reference to fig. 1 to 4 of the specification, a four-axis multifunctional device according to a preferred embodiment of the present invention is provided. Comprising a base 10, a driving cylinder 20 and a clamp sub-body 30. The base 10 includes a turntable 11, a tailstock 12, and a bridge plate 40.

The turntable 11 and the tailstock 12 are fixedly installed on the base 10, a working area is formed between the turntable 11 and the tailstock 12, and the bridge plate 40 is installed in the working area between the turntable 11 and the tailstock 12. The driving cylinder 20 and the clamp sub-body 30 are both mounted on the bridge plate 40. The jig sub-body 30 is connected to the driving cylinder 20, and a product to be processed is mounted on the jig sub-body 30. The driving cylinder 20 can push the clamp sub-body 30 to rotate horizontally.

Install driving motor on the revolving stage 11, the driving point is separated and can be driven the bridge plate 40 and overturn on four-axis multi-functional device, sets up the anchor clamps daughter 30 like this and can follow the bridge plate 40 and overturn together, realizes the processing that a clamping can the multi-angle.

The piston rod of the driving cylinder 20 is movably connected with the clamp sub-body 30. The piston rod end of the drive cylinder 20 is connected to the gripper body 30 by means of a pivot pin. When the piston rod of the driving cylinder 20 extends, the piston rod pushes the clamp sub-body 30 to rotate clockwise. When the piston rod of the driving cylinder 20 is retracted, the piston rod drives the clamp sub-body 30 to rotate counterclockwise. The clamp sub-body 30 can rotate horizontally.

A first limit stop 41 and a second limit stop 42 are mounted between the bridge plate 40 and the clamp body 30. The first limit stopper and 41 the second limit stopper 42 are mounted to the bridge plate 40 by fasteners such as bolts. Since the rotation of the jig sub-body 30 is pushed by the driving cylinder 20, the driving cylinder 20 can only be pushed and cannot be positioned, and therefore the first limit stopper 41 and the second limit stopper 42 are required to be positioned after the rotation angle is reached. The first limit stopper 41 and the second limit stopper 42 can limit the rotation angle of the jig sub-body 30 to stop at a precise position.

A clasping cylinder 50 is mounted on the bridge plate 40 on the side remote from the clamp sub-body 30. The output shaft of the holding cylinder 50 is connected to the gripper body 30. The hugging cylinder 50 includes a first oil separator 51 and a bearing 52. The external oil is introduced into the holding cylinder 50 and then flows into the first oil separator 51, and the holding cylinder 50 is rotated or stopped by the first oil separator 51. The clamp sub-body 30 needs to be braked and locked.

The second oil separator 111 is attached to the turntable 11. External oil enters through a built-in oil pipeline on the tailstock 12, then flows into the bridge plate 40, and then passes through a second oil separator 111 on the rotary table 11, so that the circulation of the oil is realized. The tailstock 12 and the rotary table 11 are rotatably connected with a side plate 13, and the side plate 13 is connected with the bridge plate 40. When the side plate 13 rotates on the tailstock 12 and the turntable 11, the bridge plate 40 is rotated together.

To accommodate products of different sizes, reference is made to fig. 1. A step-up plate 60 is installed between the tailstock 12 and the floor and between the turntable 11 and the floor. The step-up plate 60 can raise the height of the turntable 11 and the tailstock 12. When the height of the product mounted on the jig sub-body 30 is excessively high, the product does not collide with the ground while the product rotates along with the product.

To secure the product mounted on the jig sub-body 30, refer to fig. 4. A plurality of clips 31 are mounted on a side of the clip sub-body 30 remote from the bridge plate 40. The clamp 31 is capable of clamping a product placed on the clamp body 30.

The implementation principle of the embodiment is as follows: when the numerical control machine tool is used for processing products, the four-axis clamp 31 is needed for changing the angle of the products. The worker places the product on the jig sub-body 30, and the jig 31 on the jig sub-body 30 clamps the product on the jig sub-body 30. Then the driving cylinder 20 pushes the clamp sub-body 30 to rotate to the designated angle, and the clamp sub-body 30 is fixed at the current angle by the first limit stop 41 or the second limit stop 42. After the external oil is introduced into the clasping cylinder 50, the clasping cylinder 50 can play a role in clasping the brake. On outside fluid lets in tailstock 12, under the effect of the inside fluid gas circuit of tailstock 12, tailstock 12 drives curb plate 13 and rotates to drive the bridge plate 40 and rotate, make the product rotate in vertical direction. The change of a plurality of angles can be completed by one-time clamping through the arrangement.
