Problems solved by technology

[0003] The pick-up jaws of the above-mentioned device belong to the clamping mechanism widely used in the prior art, but the above-mentioned clamping mechanism still has obvious defects in the use process: 1. The above-mentioned device only clamps the casting through the clamping jaws. Take, for larger castings, it is not provided with an effective device to assist the castings to break away from the mold, which is not conducive to the non-destructive shedding of the castings; 2. The above-mentioned devices and the castings in the prior art usually move through a translational path perpendicular to the direction of the casting mold Clamping, and this kind of clamping method requires the mechanical arm to provide a greater clamping force before the casting is separated. For large castings with a large combined area between the casting and the mold, it requires a greater force to fall off the mold, and the simple Using the translational gripping method of the mechanical arm will easily lead to the phenomenon of claw detachment. If the clamping force is increased, the gripper and the casting may be damaged. Therefore, the use of the above-mentioned translational picking method is not scientific enough.

Embodiment 1

[0023] A flexible clamping spray cooling die-casting robot dedicated to a die casting machine, comprising a mechanical arm 1 and a clamping manipulator 2, the clamping manipulator 2 includes a gripper carrier 3, and the gripper carrier 3 is connected to the manipulator through a flange connection ring 4 at the tail The flange 5 on the 1 is fixedly connected, and the side of the gripper carrier 3 away from the flange connection ring 4 is provided with a number of sliding grooves 6 in an annular array along its axis, and the extension lines of the several sliding grooves 6 intersect with the gripper carrier. The axis of 3, a number of sliding grooves 6 are slidably provided with translation jaws 7, and the translation jaws 7 are driven by the translation mechanism to move synchronously and telescopically. The inside of the jaw carrier 3 is provided with an instrument compartment 8, and the jaw carrier 3 is close to The shaft center on one side of the translation gripper 7 is prov...

Embodiment 2

[0026] In this embodiment, the translational drive mechanisms of several translational jaws 7 include, but are not limited to, motor drive or pneumatic transmission. The above two moving modes of translational jaws 7 are commonly used in the prior art, and will not be omitted here. Repeat.

Embodiment 3

[0028] In this embodiment, the number of the plurality of sliding grooves 6 is three, and the three translation jaws 7 are provided with a pressure sensor 26 on the abutting side of the workpiece to be taken. The pressure sensor 26 is electrically connected to the main control PLC, and the main control The PLC is used to control the translation drive mechanism to control the expansion and contraction of the translation jaws 7. The three sliding grooves 6 and the corresponding number of translation jaws 7 are provided to ensure effective clamping and fixation of the casting. The pressure sensor 26, by setting the pressure threshold value of the pressure sensor 26, can be adjusted in a targeted manner during the process of picking up different castings, so as to prevent the castings from being damaged or disengaged due to the excessive or small clamping force of the translation jaws 7 occur.

Abstract

The flexible clamping spray cooling die-casting robot special for the die-casting machine comprises a mechanical arm and a clamping manipulator, the clamping manipulator comprises a clamping jaw carrier, and the clamping jaw carrier is fixedly connected with a flange plate on the mechanical arm through a flange connecting ring at the tail; and a plurality of sliding grooves are formed in the side, away from the flange connecting ring, of the clamping jaw carrier in an annular array mode along the axis of the clamping jaw carrier, the same circular-arc-shaped telescopic connecting rod is arranged in the action groove and the instrument cabin, and the end, close to the translation clamping jaw, of the circular-arc-shaped telescopic connecting rod is fixedly connected with a loosening suction cup. The casting is adsorbed before being clamped by the clamping jaw, the casting is promoted to be separated from the mold through high-speed vibration, and after the vibration process is completed, the loosening suction cup does limited-angle movement around the axis of the arc-shaped telescopic connecting rod through movement of the lifting lead screw, so that the casting can be peeled off on the mold at a certain angle; and the lossless and rapid separation of the large casting is effectively ensured.
