Description

Technical Field

[0001] The utility model relates to the technical field of industrial robot detection equipment, in particular to an industrial robot performance detection device. Background Art

[0002] An industrial robot is a multi-joint manipulator or multi-degree-of-freedom machine device for the industrial field. It can execute and work automatically and is a machine that relies on its own power and control capabilities to achieve various functions. In the field of performance testing of industrial robots, camera machine vision detection systems are usually used to test the various performance of industrial robots, especially the posture accuracy, posture repeatability, multi-directional posture accuracy change, distance accuracy, distance repeatability, position stabilization time, position overshoot, position characteristic drift, trajectory accuracy, trajectory repeatability, redirection trajectory accuracy, corner deviation, corner velocity characteristic minimum positioning time, swing deviation and other indicators specified in the "GBT12642-2013 Industrial Robot Performance Specification and Test Method".

[0003] At present, when testing the gripping force of industrial robots, different devices are usually needed for testing, which increases the production cost of the testing devices and the inconvenience of replacing and using the testing devices. In addition, some testing devices often pose certain risks during the testing process due to inadequate protective measures and the excessive weight of some tested objects.

[0004] Patent publication number CN 209069610 U discloses an industrial robot performance testing device, comprising a load block and four connecting blocks, the four connecting blocks being equidistantly arranged at the top of the load block, the four connecting blocks being threadedly connected to four threaded seats arranged at the top of the load block, the tops of the four connecting blocks being fixedly provided with a first clamping rod, a second clamping rod, a connecting rod, and a third clamping rod, respectively, and the top of the first clamping rod being fixedly provided with a first limit block. The utility model facilitates testing the clamping force of the industrial robot by providing the first clamping rod, the second clamping rod, the hook ring, and the third clamping rod, and detects the working condition of the industrial robot based on different contact areas, thereby judging the performance of the industrial robot.

The provided weight slot facilitates adding or removing weights as needed, thereby adjusting the overall weight of the device.

[0005] However, this device requires disassembly and assembly of multiple clamping rods to achieve clamping working states with different contact areas of the industrial robot, which is relatively cumbersome to operate. Summary of the Invention
