The invention, which belongs to the technical field of the metering device design, discloses a detection apparatus for parallelism degree between a workpiece hole and a machine tool guide rail. The detection apparatus is composed of a vertical rod, a horizontal bar, meter rods, a dial indicator, fastening screws, a shaft seat, a measuring head, a detection rod, and a bridge plate assembly. The vertical rod is arranged inside a hole formed in the left end of the horizontal bar in a sleeving mode; the horizontal meter rod passes through the dial indicator and the vertical rod; the shaft seat is arranged at the lower end of the vertical rod and passes through the vertical rod and is fixed by the fastening screw; the vertical meter rod passes through the dial indicator and the shaft seat and is fixed by the fastening screw; the detection rod is inserted into a to-be-detected hole; the measuring head and the detection rod are in contact directly; and the bridge plate assembly is installed on a machine tool guide rail. A pointer of the dial indicator is adjusted to be at a zero point; the bridge plate assembly moves along the machine tool guide rail; and a reading number of the dial indicator is observed and a maximum value represents a parallelism error between the to-be-detected hole and the guide rail. According to the invention, the provided detection apparatus has advantages of simple manufacturing, convenient usage, wide application range, high moving precision, and convenient measuring head position adjustment.
Description
technical field [0001] The invention relates to the technical field of measuring instrument design, in particular to a device for detecting the parallelism between a workpiece hole and a machine tool guide rail. Background technique [0002] With the development of the machinery industry, the requirements for the shape and position error of the parts are getting higher and higher. Therefore, there are various detection tools for the shape and position errors of the parts on the machine. When the detection elements of different parts change, Sometimes it is necessary to have relative movement between the parts and the testing equipment. The traditional testing equipment mostly uses a part of the testing elements for sampling testing. The accuracy is difficult to meet, the adjustment of the testing equipment is inconvenient, and the application range is narrow. When it is necessary to move the position of the probe, The movement precision is low, so it is necessary to design a...
