Problems solved by technology

Since the fixed part of the dial gauge used cannot be moved, the angle of the dial gauge needs to be adjusted during use. If the angle is wrong, the fixed part needs to be repeatedly loaded and unloaded on the dial gauge to adjust to a suitable angle. The operation is cumbersome and complicated. Seriously affects the detection efficiency of the clamping rod groove
At the same time, repeated loading and unloading of fixing parts to adjust the angle will not only affect the detection accuracy of the dial gauge, but also cause the dial gauge to be easily damaged during frequent installations, resulting in a high replacement rate of dial gauge testing equipment in the department

Abstract

The invention relates to the detection field of a drilling machine and particularly relates to a detection device fixing device and a method for detecting position precision of a rod clamping groove. According to the method, a screw rod is hinged between two clamping plates, the two clamping plates are provided with an adjusting mechanism, so the detection device fixing device can be directly mounted on a dial gauge through the adjusting mechanism, and loss of the dial gauge is reduced. The screw rod is hinged between the two clamping plates, the detection device fixing device can be directly mounted on the dial gauge, an angle of the dial gauge can be flexibly adjusted, repeatedly dismounting and mounting the fixing device during angle adjustment of the dial gauge can be avoided, not only can loss of the dial gauge be reduced, but also workload of workers can be reduced, detection efficiency is further improved on the condition that detection precision is improved, and detection cost is reduced.

Description

technical field [0001] The invention relates to the field of drilling machine detection, in particular to a detection instrument fixing device and a method for detecting the position accuracy of clamping rod grooves. Background technique [0002] Drilling rig is a commonly used equipment in the production and processing of printed circuit boards. Due to long-term vibration during the production process, the clamping rod groove of the drilling rig is often loosened (the clamping rod groove is usually called the clamping PIN groove), resulting in the use of the clamping rod groove to locate the board. Deviation occurs during the drilling process, causing the drilling deviation, which eventually causes the printed circuit board to be scrapped. There are generally two types of clamping grooves: V-shaped groove and parallel groove. When producing multi-layer boards, it is necessary to ensure that the V-shaped groove is concentric with the spindle drill, and the parallel groove mu...
