[0002] The dial indicator is generally used to measure the shape and position error of the workpiece. When the traditional dial indicator measures whether the surface of the workpiece is flat, it usually needs to take the workpiece to the grinder to grind the back (the other side), and then put the workpiece on the lathe In general, the front of the workpiece is measured with a dial indicator, which takes a long time to operate and has many processes, which is not conducive to mass production, and the traditional dial indicator cannot measure the back of the workpiece

A reverse dial indicator comprises a dial bezel, wherein a rack pin and a dial plate are arranged in the dial bezel, a blocking cap is arranged on the rack pin, a little-scale indicator and a big-scale indicator are arranged on an outer wall of the dial plate, and a little-scale gear, a big-scale gear and a transmission gear are arranged on an inner wall of the dial plate. The little-scale gear drives the little-scale indicator, the big-scale gear drives the big-scale indicator, the upper portion of the little-scale gear is meshed with the big-scale gear, the lower portion of the little-scale gear is meshed with the transmission gear, and the transmission gear is meshed with an outer wall of the rack pin. The reverse dial indicator has the advantages that the rack pin is connected with a tension spring, the other end of the tension spring is fixed on an inner wall of the upper portion of the dial plate, and a correction hook is arranged at the lower end of the rack pin. The correction hook comprises a vertical hook body, wherein a detection rod which is perpendicular to the hook body is arranged below the hook body, and the detection rod is contacted with the back of a workpiece.
Description
technical field [0001] The invention relates to a dial indicator, in particular to a reverse dial indicator, which belongs to the field of machining measuring tools. Background technique [0002] The dial indicator is generally used to measure the shape and position error of the workpiece. When the traditional dial indicator measures whether the surface of the workpiece is flat, it usually needs to take the workpiece to the grinder to grind the back (the other side), and then put the workpiece on the lathe In general, the front of the workpiece is measured with a dial indicator, which takes a long time to operate and has many processes, which is not conducive to mass production, and the traditional dial indicator cannot measure the back of the workpiece. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art, to provide a reverse pull, which can be hooked on the back of the workpiece, to correct the flatness...
