Description

Technical Field

[0001] This utility model relates to the field of mechanical gripper technology, and in particular to a feeding mechanical gripper for CNC lathes. Background Technology

[0002] A robotic arm is an automated operating device that can mimic certain movements and functions of a human hand and arm to grasp, move objects, or operate tools according to a fixed program. It is often used for feeding CNC lathes. In conventional robotic arm use, after the chassis is fixed to the ground, the control arm on the top of the chassis controls the fixed clamp to move, and uses the fixed clamp to transport the workpiece to the upper part of the CNC lathe.

[0003] Existing CNC lathe feeding mechanical grippers, especially when handling heavy equipment, usually require support at the gripper arm to ensure that the gripper arm can provide sufficient support during handling and to prevent the gripper arm from being too weak and bending, thus shortening the service life of the equipment. Therefore, a CNC lathe feeding mechanical gripper is proposed.

[0004] A CNC lathe feeding mechanical gripper disclosed in publication number CN220260319U includes a chassis and a limiting plate. A control arm is rotatably mounted on the top of the chassis, and a fixed clamp is rotatably connected to the top of the control arm. The fixed clamp has a C-shaped cross-section. Two connecting frames are fixedly mounted on the top of the limiting plate. A rotating block is rotatably connected to the inner wall of each connecting frame, and an electric telescopic rod is fixedly mounted on the top of each rotating block. The top of the limiting plate is movably connected to one end of the control arm, and one end of the electric telescopic rod is fixedly mounted to the surface of the control arm. The two connecting frames are symmetrically distributed about the limiting plate. This application, by installing the limiting plate at one end of the control arm and mounting the electric telescopic rod on the top of the limiting plate via the connecting frames and rotating block, facilitates adjustment of the limiting plate's position using the electric telescopic rod. This allows for the pushing of the workpiece when it becomes stuck between the fixed clamps.

[0005] Although the aforementioned patent achieves the goal of installing a limit plate at one end of the control arm, with an electric telescopic rod mounted on the top of the limit plate via a connecting frame and a rotating block, allowing for adjustment of the limit plate's position and facilitating the pushing of the workpiece when it gets stuck between the clamps, this device makes it inconvenient to disassemble the gripper, thus hindering regular maintenance and replacement of the gripper.

[0010] As a further embodiment of this utility model, a connecting rod C is rotatably connected to the middle of the surfaces of the two connecting rods A, and a fixing block is rotatably connected to the end of the connecting rod C. The fixing block serves to support the connecting rod C.

[0011] As a further embodiment of this utility model, the hydraulic cylinder is fixedly connected to the bottom of the gripper arm, and several anti-slip blocks are installed on the surface of the gripper body. The anti-slip blocks serve to prevent slipping.

[0012] As a further embodiment of this utility model, an upper bracket is fixedly connected to one side of the long arm of the gripper, and the rotating joint is fixedly connected to one side of the upper bracket. The upper bracket serves to support the long arm of the gripper.

[0013] As a further embodiment of this utility model, a vertical pole is fixedly connected to the bottom of the upper support, and a rotating mechanism is fixedly connected to the bottom of the vertical pole. The rotating mechanism drives the gripper body to rotate.

[0016] (III) Beneficial Effects

[0017] This utility model provides a feeding mechanical gripper for CNC lathes, which has the following beneficial effects:

[0018] 1. This CNC lathe feeding mechanism gripper, through the setting of the support mechanism, activates the hydraulic rod at the bottom of the gripper arm when supporting the gripper arm. The hydraulic rod extends and retracts until it reaches a suitable length, and then supports the bottom of the gripper arm, providing an upward support force. When the gripper body is moving heavy objects, it can effectively reduce the force on the gripper arm, thereby achieving the effect of protecting the gripper arm and preventing the gripper arm from bending due to excessive force, thus shortening the service life of the equipment.

[0019] 2. This CNC lathe feeding mechanical gripper, through the setting of disassembly and drive mechanisms, when in use, the drive motor is started, and the drive motor drives the threaded rod at the bottom to rotate. This causes the threaded connector to move up and down along the surface of the threaded rod under the limit of connecting rod C. With the cooperation of connecting rods A, B, and C, the two gripper bodies at the bottom can move relative to each other, clamping the material in the middle. The positioning bolts on the top gripper fixing plate can be unscrewed to separate the gripper body from the equipment, which is convenient for the staff to maintain and replace the gripper body regularly, ensuring that the equipment can be used normally.

A gripper arm 5 is fixedly connected to the top of the disassembly mechanism 2, and a support mechanism 6 is fixedly connected to the bottom of the gripper arm 5. The support mechanism 6 protects the gripper arm 5 from excessive force, preventing bending and shortening the equipment's service life. The disassembly mechanism 2 includes a threaded connection to the top of the gripper fixing plate 1. The connecting plate 201 of the part has four positioning bolts 202 threadedly connected to its surface, and a hydraulic cylinder 203 is fixedly connected to the top of the connecting plate 201; the drive mechanism 4 includes a drive motor 401 fixedly connected inside the motor housing 3, a threaded rod 402 fixedly connected to the output end of the drive motor 401, a threaded connector 403 threadedly connected to the surface of the threaded rod 402, four connecting rods A404 rotatably connected to the surface of the threaded connector 403, a connecting rod B405 rotatably connected to the end of the connecting rod A404, and a gripper body 406 fixedly connected to the end of the connecting rod B405; the support mechanism 6 includes a fixed joint 601 fixedly connected to the bottom of the gripper arm 5, a hydraulic rod 602 rotatably connected to the surface of the fixed joint 601, and a rotating joint 603 rotatably connected to the back of the hydraulic rod 602;

[0027] Two connecting rods A404 are rotatably connected to connecting rod C7 at the middle of their surfaces. The end of connecting rod C7 is rotatably connected to a fixing block 8. The fixing block 8 serves to support connecting rod C7.

[0028] The hydraulic cylinder 203 is fixedly connected to the bottom of the long arm 5 of the gripper. Several anti-slip blocks 9 are installed on the surface of the gripper body 406. The anti-slip blocks 9 play a role in preventing slipping.

[0029] An upper bracket 10 is fixedly connected to one side of the long arm 5 of the gripper, and a rotating joint 603 is fixedly connected to one side of the upper bracket 10. The upper bracket 10 serves to support the long arm 5 of the gripper.

[0030] A vertical pole 11 is fixedly connected to the bottom of the upper support 10, and a rotating mechanism 12 is fixedly connected to the bottom of the vertical pole 11. The rotating mechanism 12 drives the gripper body 406 to rotate.

[0032] The bottom of the motor box 1202 is fixedly connected to a base 13, which is welded to an external connection device. The base 13 serves to support the upright 11.

[0033] In this invention, the working steps of the device are as follows:

[0034] First step: When supporting the long arm 5 of the gripper, activate the hydraulic rod 602 at the bottom of the long arm 5. The hydraulic rod 602 extends and retracts until it reaches a suitable length, and then supports the bottom of the long arm 5, providing an upward support force. When the gripper body 406 moves heavy objects, it can effectively reduce the force on the long arm 5.

[0035] The second step: When in use, start the drive motor 401. The drive motor 401 drives the threaded rod 402 at the bottom to rotate, which causes the threaded connector 403 to move up and down along the surface of the threaded rod 402 under the limit of the connecting rod C7. With the cooperation of connecting rods A404, B405 and C7, the two gripper bodies 406 at the bottom can move relative to each other, clamping the material in the middle. The positioning bolts 202 on the top gripper fixing plate 1 can be unscrewed to separate the gripper body 406 from the equipment.
