The invention discloses a portable inner hole taper detection device, and belongs to the technical field of taper rapid detection. The portable inner hole taper detection device comprises a handle, adial indicator, a split type measuring head, a transmission measuring rod and a workpiece, wherein the dial indicator is fixedly connected to the top end of the handle, the indicator head penetrates through the handle to be in contact with the transmission measuring rod, the split type measuring head is fixedly connected to the tail end of the handle and inserted into the workpiece to detect the taper of an inner hole, the transmission measuring rod is located in the handle, and the two ends of the transmission measuring rod are in contact with the indicator head and the split type measuring head respectively. According to the portable inner hole taper detection device, the large diameter and the small diameter of the inner taper hole of the workpiece are measured through the split type measuring head, so that the phenomenon that the inner taper hole is jammed when a taper rod or a plug gauge is used for detecting the inner taper hole is avoided, and the detection cost is reduced whilethe operation technical difficulty is reduced.
Description
technical field [0001] The invention relates to the technical field of rapid taper detection, in particular to a portable inner hole taper detection device. Background technique [0002] At present, the lathe spindles, external spindles, etc. on the market have the characteristics of matching taper surfaces in the inner hole of the nose end of the shaft core and the outer circumference of the nose end. Quality control and other departments usually use standard taper rods and taper plug gauges combined with sludge when testing whether the taper of the inner cone hole and outer cone surface at the nose end of the shaft core or other parts meets the design requirements. The coverage rate on the core is used to measure the taper of the inner hole; the three-coordinate measuring instrument combined with the probe is used to measure the size of the outer taper at the corresponding position. The measurement of the outer taper can be easily done under the action of the three-coordi...
