Description

Technical Field

[0001] The utility model belongs to the technical field of shaft part processing, and in particular relates to a shaft forging processing calibration tool. Background Art

[0002] Shaft parts are one of the typical parts often encountered in hardware accessories. They are mainly used to support transmission components, transmit torque and bear loads. According to the different structural forms of shaft parts, they can generally be divided into three categories: smooth shafts, stepped shafts and special-shaped shafts; or into solid shafts, hollow shafts, etc.

[0003] The patent application with announcement number CN217255004U discloses a shaft forging processing calibration tool, including: a base, two support blocks are fixedly installed on the top surface of the base, and the top surface of the support block is provided with a placement groove; a calibration component, the calibration component is arranged on one side of the base, and is used to calibrate the shaft forgings. By setting the placement groove, when in use, the staff puts the shaft forging into the placement groove, and by setting a dial indicator, when the staff puts the shaft forging into the placement groove, the pointer of the dial indicator is made close to the shaft forging by rotating the universal tube, and the error on the shaft forging is measured by the dial indicator, which is convenient for the staff to calibrate the error on the shaft forging, and by setting an electric push rod, the push block is pushed to move by the telescopic shaft of the electric push rod, so that the dial indicator measures the error of the two sides of the shaft forging, and the calibration effect is further improved.

[0004] The calibration tool in the above technical solution cannot adjust the distance between the dial indicator and the shaft forging when calibrating the shaft forging. If the shaft forging is thicker, the measuring range of the dial indicator will be reduced. If the shaft forging is thinner, the measuring needle of the dial indicator cannot contact the shaft forging, thereby reducing the working effect of the calibration tool on the calibration measurement of the shaft forging.

[0005] In summary, the utility model therefore provides a shaft forging machining and calibration tool to solve the above-mentioned problems. Utility Model Content
