Embodiment Construction

[0026] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0027] like figure 1 , 2 As shown, a self-centering deep hole parameter measurement device includes a centering device, a measurement recording device and a traveling device. The centering device is located in the deep hole of the workpiece 1, and the centering device includes a sleeve 2, a centering shaft 6, two cones 5, two bearings 3, six measuring rods and a spring 12, and the centering shaft 6 is located on the axis of the sleeve 2, and the centering shaft 6 is connected to the sleeve 2 through two bearings 3, two sets of through holes are opened on the wall of the sleeve 2, each set of through holes is three, and three The through holes are evenly distributed on the cross section perpendicular to the axis of the sleeve 2; the two cones 5 and the spring 12 are located in the sleeve 2, and are movable sleeved on the centering shaft 6, and ...

Abstract

The invention discloses a self-centering depth hole parameter measurement device, comprising a centering device, a measurement recording device and a processing device. The centering device is arranged in a depth center of the workpiece and comprises a sleeve, a centering shaft, three conical bodies, six measurement rods and a spring. The recording device comprises two distance measurement sensors which are fixed on two ends of the centering shaft; the two distance measurement sensors are electrically connected to the control terminal; the processing device comprises a second motor, a reel and a flexible rope; one end of the flexible rope is connected to one end of the centering shaft; the other end of the flexible rope is wound on the reel; the rotation shaft of the reel is connected to the output shaft of the second motor; the two conical bodies move toward the two sides under the resetting force of the spring and a measurement rod slides inside a sliding groove, which causes the measurement rod to radially move outwardly until the measurement head of the measurement rod is abutted against the inner wall of the workpiece depth hole, and thus the two conical bodies are under a force balance state; and, at this time, the centering shaft is positioned on the axis of the depth hole, which achieves the goal of depth hole shaft centering and guarantees the precise measurement of the related parameters of the workpiece depth hole.

Description

technical field [0001] The invention belongs to a deep hole measuring device, in particular to a self-centering deep hole parameter measuring device. Background technique [0002] In modern industries such as airplanes, ships, and large-scale precision instruments, the processing and testing of shaft hole parts is always a major problem affecting production. The accuracy of the hole diameter, deep hole roundness, and straightness of such parts is an important factor to ensure product quality. factor. [0003] At present, the traditional inner diameter measurement method mainly uses calipers and calipers to measure the parts after processing. This type of measurement method belongs to contact measurement, which is inconvenient to operate, difficult to guarantee accuracy, and has large human influence factors. Moreover, the test is even more inconvenient for parts with deep or ultra-deep holes with a hole depth-to-aperture ratio greater than 5. In response to this situation,...
