Abstract

The invention provides an automation straightener for a drilling tool, which comprises a base, a pressure machine, a roller, a lifting device, a movable cushion block, a detecting trolley, and a control module, wherein the base is used for supporting; the pressure machine is used for pressing against the straightening drilling tool and is movably arranged on the upper part of the base; the roller is used for rotating the drilling tool, and one end of the roller is arranged on the base in a stretchable connection way; the lifting device is used for jacking the drilling tool, and one end of the lifting device is fixedly arranged on the base and positioned at the outer side of the roller; the movable cushion block is used for supporting the drilling tool, and one end of the movable cushion block is movably arranged on the base; the detecting trolley is used for detecting shape and position data of the drilling tool and is movably arranged on the base, and transmits the data to the control module; and the control module receives the data transmitted by the detecting trolley, and controls the actions of the pressure machine, the roller, the lifting device, the movable cushion block and the detecting trolley according to the data and a preset program. The automation straightener for the drilling tool realizes automatic detection and automatic control when the drilling tool is repaired by using the detecting trolley and the control module, thereby largely reducing human intervention, realizing the automation for drilling tool repair and achieving high accuracy of drilling tool repair, rapid speed, and high stability.

Description

technical field

[0001] The invention relates to an automatic drilling tool straightening machine. Background technique

[0002] Drilling tools are prone to bending deformation due to loads such as compression, bending, and torsion during use. The occurrence of this situation not only affects the normal use and non-destructive testing of drilling tools, but also reduces the fatigue resistance of drilling tools and causes drilling tool fracture accidents. Therefore, drill tools need to be repaired frequently. In the process of drilling tool repair, it is of great significance to correct the bending deformation of the drilling tool in time by using the straightening process to ensure the normal operation of the subsequent inspection process and prolong the service life of the drilling tool. At present, the curvature of drilling tools and the straightness after straightening mainly rely on manual visual inspection, and the straightening effect completely depends on human subje...
