Hand-held dial indicator detection device

Abstract

The invention provides a hand-held dial indicator detection device. The hand-held dial indicator detection device comprises a miniature screw rod, a reference supporting plate, a holding frame, a pinching rod, L-shaped follow-up rods, a circular rotating seat, a circular connecting concave seat, a T-shaped guide rod, a hand-rotating positioning screw, a sleeving ring seat and an aluminum protective cylinder; the left side of the annular side surface of the miniature screw rod is provided with the reference supporting plate, and the circular rotating seat is embedded in the circular connecting concave seat; the T-shaped guide rod is installed on the right side of the inner wall of the holding frame, and the L-shaped follow-up rods are symmetrically arranged on the upper side and the lower side of the annular side face of the pinching rod, the design solves the problem that an original dial indicator is inconvenient to hold and use, a sleeving ring seat is installed on the upper side of the annular side face of the measuring rod, and the hand-rotating positioning screws are symmetrically installed on the front side and the rear side of the interior of the sleeving ring seat. According to the design, the problem that an original measuring rod for the dial indicator is prone to being collided and damaged when not used is solved, and compared with the prior art, the hand-held dial indicator detection device is reasonable in structure, convenient to hold for adjustment and use, wide in application range, compact in structure and high in reliability.

Description

technical field [0001] The invention is a hand-held dial indicator detection device, which belongs to the technical field of dial indicator detection. Background technique [0002] The dial indicator is a general-purpose length measuring tool made of a precision rack and pinion mechanism. It usually consists of a probe, a measuring rod, a shock-proof spring, a rack, a gear, a hairspring, a round dial, and a pointer. For the surface of the sheet metal processing parts in various parts, it is usually necessary to use a dial indicator for error detection, but the previous dial indicators have a single shape, and when the surface error detection of sheet metal processing parts is performed, the dial indicator often appears There is a gap between the probe and the surface of the sheet metal processing part, or the phenomenon of mutual clamping is not accurate, which affects the accuracy of the test result. Although the existing dial indicator can be used by hand, it is easy to sl...

Problems solved by technology

For the surface of the sheet metal processing parts in various parts, it is usually necessary to use a dial indicator for error detection, but the previous dial indicators have a single shape, and when the surface error detection of sheet metal processing parts is performed, the dial indicator often appears There is a gap between the probe and the surface of the sheet metal processing part, or the phenomenon of mutual clamping is not accurate, which affects the accuracy of the test result. Although the existing dial indicator can be used by hand, it is easy to slip when holding it, and There is no corresponding protective structure for the measurement, which leads to the fact that the measuring rod is easily damaged by collision during the process of carrying the dial indicator. Now there is an urgent need for a hand-held dial indicator detection device to solve the above problems
