Description

Technical Field

[0001] The utility model relates to the technical field of stamping robots, in particular to a clamp for a stamping robot. Background Art

[0002] A clamp is a common tool used by people to clamp objects that need to be processed, especially a clamp for stamping robots. However, with the continuous development of technology, people have higher and higher requirements for efficient clamps for stamping robots, resulting in traditional efficient clamps for stamping robots being unable to meet people's usage needs.

[0003] For example, a clamp for a stamping robot (Announcement No.: CN213499032U), the device includes a base, a rotating plate, the rotating plate is located above the base, a mounting groove is provided at the upper end of the base, a motor is fixed in the mounting groove, the output shaft of the motor is fixed to the rotating shaft, the rotating shaft is connected to the base through a bearing, the rotating plate is fixed to the upper end of the rotating shaft, a fixed plate is fixed to the upper end of the rotating plate, a slide groove is provided at the upper end of the rotating plate, a moving plate is installed in the slide groove, two mounting plates are fixed to the upper end of the rotating plate, a screw rod is provided between the mounting plates, the two ends of the screw rod are respectively connected to the mounting plates through bearings, the screw rod passes through the moving plate and is connected to the moving plate through threads, the fixed plate and the moving plate are respectively fixed at the opposite ends, the upper clamp plates are respectively provided above the lower clamp plates, the upper end of the upper clamp plates is fixed to a spring, the upper end of the spring is fixed to a fixed block, and the fixed blocks are respectively fixed to the fixed plate and the moving plate. The clamp for the stamping robot can be rotated for use, and the service life of the clamp can be extended.

[0004] When the device is in use, the recoil force generated during stamping is reduced through spring one and spring two, so as to avoid damage to the fixture. When the support column of the device transfers the downward pressure to spring two, spring two contracts. At this time, the rotating shaft will also be subjected to downward pressure, and the downward pressure on the rotating shaft will be transmitted to the motor. Long-term use will cause damage to the motor. Therefore, we need to propose a fixture for a stamping robot. Utility Model Content
