In recent years, in the automated CNC industry, more and more companies have adopted robot-related automated equipment to realize automated production of machine tools.
[0003] However, in practical applications, robots have many problems, both from an economic and technical perspective. For example, in loading and unloading lathes, the current loading grippers are generally three-claw cylinders or two-claw cylinders with gripping fingers to pick up and place workpieces, and the grippers are often difficult to push the materials to the correct position after being released. For another example, in loading lathes, when using robots or truss manipulators to load materials, it is often impossible to determine whether the material is in place when calibrating the point, resulting in difficulty in calibrating the point.

[0017] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0018] like Figure 1-3 As shown, the device includes a cylinder 1, a clamping jaw 2 and a material ejecting device 3, and the clamping jaw 2 and the material ejecting device 3 are both mounted on the cylinder 1. The clamping jaw 2 has a plurality of clamping arms 21, and each clamping arm 21 can be opened and closed under the operation of the cylinder 1.
[0019] The ejecting device 3 mainly comprises a push plate 31 and a plurality of washers 32, a plurality of sliding screws 34 and a plurality of springs 35, the number of which is the same as the number of the clamping arms 21. The push plate 31 has a plurality of branch plates 33 extending from the center in different directions, and the number of the branch plates 33 is the same as the number of the washers 32. Preferably, the angles between each two adjacent branch plates 33 are equal.
[0020] Preferably, the number of the gasket 32, the sliding screw 34 and the spring 35 of the ejecting device 3, and the branch plates 33 of the push plate 31 are the same as the number of the clamping arms 21 of the clamping jaw 2, generally 2-4, more preferably 3. The center of the push plate 31 is located at the center of each clamping arm 21, and each branch plate 33 of the push plate 31 is located between each adjacent clamping arm 21.
[0021] Each gasket 32 is mounted on the cylinder 1 through a connecting piece and is penetrated by a sliding screw 34, and each sliding screw 34 is also connected to each branch plate 33. The gasket 32 is roughly rectangular and about 5 mm thick. One end of the gasket 32 is provided with a mounting hole 36 and can be mounted on the cylinder 1 with corresponding screws and other mounting pieces. The other end is penetrated by the sliding screw 34, and the two can slide relative to each other. The sliding screw 34 is a slotted large cylindrical head screw, and one end of the sliding screw 34 where the head is located is close to the gasket 32. After penetrating the gasket 32, the sliding screw 34 extends to the end of the branch plate 33 of the push plate 31, and the other end is connected to the branch plate 33.
[0022] In addition, the springs 35 are respectively mounted on the outside of the slide screws 34 .
[0023] When the device is installed on a robot for use, first operate the cylinder 1 to control the clamping jaws 2 to clamp the material 4. At this time, the branch plates 33 and the sliding screws 34 of the push plate 31 of the ejecting device 3 slide toward the direction of the cylinder 1, so that the springs 35 are in a compressed state; and when preparing to place the material 4 at a position such as a lathe chuck, first leave an appropriate gap (about 1 mm) between the material 4 and the lathe chuck, loosen the clamping jaws 2, and under the action of the springs 35, the push plate 31 of the ejecting device 3 can push the material 4 to make it stably placed at the bottom of the lathe chuck.
[0024] In this way, the difficulty of robot calibration is reduced, and the material 4 can be fully placed in place. At the same time, the spring 35 device between the robot and the lathe chuck also plays a flexible transition connection role, which can avoid the impact on the life of the robot's rigid structure due to slight deviations in point positions.
[0025] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
