Problems solved by technology

The centering device is dragged by a flexible rope to move along the axial direction in the hole. This kind of movement has great limitations, and the measurement range is limited and inconvenient. When the axis of the deep hole changes, the centering The device is difficult to move and the measurement accuracy is low, and the aperture measurement of blind holes cannot be realized

Embodiment 1

[0034] Such as figure 1 As shown, a self-centering aperture measurement robot includes a centering measurement device 1 , a traveling device and a control device 51 . The centering measuring device 1 comprises a first sleeve, a centering shaft 11, two cones, two bearings, six measuring rods and a first spring, the centering shaft 11 is positioned on the axis of the first sleeve, and the centering The shaft 11 is connected with the first sleeve through two bearings. Two sets of through holes are opened on the wall of the first sleeve, each set of three through holes, and the three through holes are evenly distributed on the axis of the first sleeve. On the vertical section; the two cones and the first spring are located in the first sleeve, and are movably sleeved on the centering shaft 11, the two cones are set back, and the tapers of the two cones are respectively facing At both ends of the centering shaft 11, the first spring is arranged between the two cones; three slide s...

Embodiment 2

[0040] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that the traveling device also includes an adjustment motor 36, a screw 37 and a trident mechanism 38, the adjustment motor 36 is fixedly arranged in the second sleeve 32, and the output shaft of the adjustment motor 36 Connect with the screw rod 37 through a coupling, Figure 4 It is the schematic diagram of the trident mechanism, the center of the trident mechanism is provided with a threaded hole, the screw rod 37 is threadedly connected with the trident mechanism 38, and each connecting rod of the trident mechanism 38 is connected with a U-shaped bar 39, and the two of the U-shaped bar 39 Two short shafts are respectively connected to the side walls of two wheel frames 33 on the same axis, and the U-shaped bar 39 is also threaded with the wheel frames 33, and the adjustment motor 36 is connected to the control device 51. In this embodiment, a wired connection is used between the c...

Abstract

The invention discloses a self-centering aperture measuring robot comprising a centring measurement device, a walking device, a control device and a control terminal, wherein the walking device is connected with a centring shaft of the centring measurement device via a universal shaft connector; the walking device comprises a driving electric motor, a driving rotation shaft, a second sleeve cylinder, wheel racks and walking wheels, wherein the driving electric motor is connected with the driving rotation shaft which is connected with the second sleeve cylinder, a side wall of the second sleeve cylinder is provided with a plurality groups of wheel racks, a walking wheel is mounted at a free end of each wheel rack, a rotating axis line of each walking wheel and an axis line of the second sleeve cylinder form an acute angle of inclination, and the driving rotation shaft drives the second sleeve cylinder to rotate so as to drive a centring device to move; the control device is connected with a control terminal, a first electric motor of the centring measurement device, a range finding sensor and the driving electric motor of the walking device. Compared with a conventional measuring device, the self-centering aperture measuring robot is advantageous in that the screw type walking device is used for driving the centring measurement device to move in a hole; the self-centering aperture measuring robot is advantaged by high measurement precision, convenience of installation, flexible movement and wide application scope.

Description

technical field [0001] The invention relates to the technical field of aperture measurement, in particular to a self-centering aperture measurement robot. Background technique [0002] In the production of large precision instruments such as airplanes, ships, and trucks, the inner diameter measurement of parts is a very important process. For this reason, domestic and foreign scholars have conducted a lot of research on the inner diameter measurement in the process of parts processing. At present, common inner diameter measurement methods include inner diameter micrometer contact measurement method, Doppler effect method, laser interferometer measurement method, laser lever method and other non-contact measurement methods. The inner micrometer measurement method has low measurement efficiency, few measurement parameters, poor measurement repeatability, low stability, and is easily affected by the environment and operators. Doppler effect method, laser interferometer method...
