[0026] Embodiment

[0027] This embodiment provides a loading and unloading manipulator for a machine tool. Referring to Figure 1 and Figure 2 , it includes a rotary positioner 10, a mounting frame 11, a handling manipulator 20, a first driving cylinder 25, a second driving cylinder 26, and a third driving cylinder 27. The rotary positioner 10 is located between two machine tools, and a mounting frame 11 is fixedly connected to its rotating shaft. A slide rail is arranged on the mounting frame 11 along its length direction. The handling manipulator 20 includes two first handling manipulators and a second handling manipulator with the same structure.

[0028] Preferably, for the loading and unloading handling manipulator of the machine tool in this embodiment, one end of the rotating shaft of the rotary positioner 10 far from the handling manipulator 20 is fixedly connected with a hinge plate 24, and an arc-shaped groove is provided on the hinge plate 24. The first driving cylinder 25 is hinged on the body of the rotary positioner 10, and its telescopic end is slidably arranged in the arc-shaped groove. By controlling the telescopic movement of the first driving cylinder 25, the working posture of the handling manipulator 20 can be adjusted. In this embodiment, when the first driving cylinder 25 makes a telescopic movement, it drives the mounting bracket 11 and the handling manipulator 20 to deflect towards the machine tools on both sides, so as to realize the loading and unloading operation.

[0029] The handling manipulator 20 includes a sliding seat, a guide rail 21, a rotating cylinder 22 and a clamping jaw 23. The sliding seat is slidably mounted on the slide rail, and the guide rail 21 is slidably connected to the sliding seat perpendicular to the axis direction of the rotating shaft of the rotary positioner 10. The rotating cylinder 22 is fixedly connected to the bottom of the guide rail 21, and its rotating shaft is provided with a clamping jaw 23 for clamping and releasing workpieces.

[0030] A third driving cylinder 27 is arranged between the mounting bracket 11 and the sliding seat, and its two ends are respectively fixedly connected to the mounting block (the lockable connection point on the slide rail) and the sliding seat, and is used to drive the sliding seat to slide along the slide rail, so as to realize the horizontal movement of the handling manipulator 20 between the machine tools.

[0031] The mounting block is mounted on the slide rail through a lockable bolt, and one end of the third driving cylinder 27 is fixed on the sliding seat, and the other end is fixed on the mounting block, so that the third driving cylinder 27 can adjust its position along the slide rail, thereby adjusting the sliding position of the clamping jaw on the slide rail.

[0032] The working principle of the present utility model is as follows: The rotary positioner 10 rotates to the initial position according to a preset program or an external signal. The clamping jaw of the first handling manipulator is empty, and the clamping jaw of the second handling manipulator holds the workpiece to be processed. The first driving cylinder 25 of the first handling manipulator drives the clamping jaw to deflect to one side of the first machine tool. The third driving cylinder 27 of the first handling manipulator drives the sliding seat to slide along the slide rail to near the first machine tool. Subsequently, the second driving cylinder 26 of the first handling manipulator drives the clamping jaw 23 to descend to an appropriate position. After the clamping jaw 23 clamps the workpiece, the clamping jaw of the first handling manipulator returns to its original position, and the clamping jaw of the second handling manipulator moves to the clamping station. After the workpiece is clamped, the second handling manipulator also returns to its original position; then the third driving cylinder 27 drives the sliding seat to slide to near the second machine tool again. Similar to the above working process, the second handling manipulator takes away the workpiece processed on the second machine tool, and the first handling manipulator places the workpiece processed on the first machine tool on the clamping station of the second machine tool.

[0033] It should be noted that when the machining ends and clamping ends of the first machine tool and the second machine tool are the same (in this embodiment, the two machine tools are placed in opposite directions), the rotating cylinder 22 needs to rotate 180° to achieve workpiece commutation. During actual operation, it is adjusted according to specific machining requirements.

[0034] After the workpiece is machined on the two machine tools respectively, the gripper takes out the finished workpiece and then grabs the blank workpiece to repeat the above machining process, realizing the automatic loading and unloading of the product and the multi-process transfer loading.

[0035] Taking the above ideal embodiment based on the present application as an inspiration, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this application. The technical scope of this application is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
