Partial depression shaping device for automobile steel ring

Abstract

The invention relates to an automobile steel ring local recess shaping device. The device effectively solves the problems that steel ring repairing precision is poor, and secondary damage such as excessive resetting and pulling deformation is likely to occur. According to the technical scheme, the device comprises a transverse shaft used for fixing a steel ring, a supporting unit and a reset hydraulic cylinder, wherein the supporting unit and the reset hydraulic cylinder can be installed on the transverse shaft, the reset hydraulic cylinder is provided with an inter-layer, hydraulic oil is contained in the inter-layer, an oil inlet channel and an oil return channel are arranged between the inter-layer and the interior of the hydraulic cylinder in a communicating mode, a vertical polish rodattached with a piston is arranged on the piston in a penetrating mode, the polish rod can slide up and down relative to the piston, the lower end of the polish rod presses an orifice, located in theinner cylinder, of the oil return channel and seals the orifice, the upper end of the polish rod is located at the upper end of the piston and coaxially sleeved with a hollow rod, and the upper end of the hollow rod extends out of an outer cover and is in threaded connection with the inner wall of the hollow rod. According to the device, excessive resetting of the steel ring can be avoided, resetting is more accurate, and meanwhile secondary damage caused by the fact that the steel ring is pulled into a non-circular shape in the repairing process is avoided.

Description

Technical field[0001]The present invention relates to the field of auto repair, and is specifically a local recessed shaping device for automotive steel rings.Background technique[0002]The automobile steel ring is also known as the wheel, which is the installation basis of the tire. During the driving process, if the high speed passes through the deep pit or steep slope, the steel ring is partially depressed inwardly, and the steel ring is currently repairing the steel ring, and steel is generally steel On a horizontal axis, the hydraulic cylinder is used to reset it to the top recessed position, and when the hydraulic cylinder is turned to the top steel ring, the maintenance person visually controls the start and stop of the hydraulic cylinder, and cooperates with the probe repeated detection And repair, more operation, long and accurate, and it is easy to ensure excessive reset, once the reset is over, due to the outer wall of the steel ring as the arched structure, the inner rese...
