Embodiment Construction
[0011] The present invention will be further described below in conjunction with the accompanying drawings.
[0012] Such as Figure 4 with Figure 5 As shown, the feature of this inner hole detection method of the present invention is to select two hole sections 140, 141 along the channel 13, establish a reference axis 15 with the center point of the two hole sections 140, 141, and observe the diameter of the channel 13. Deviations between the center points of other hole sections 16 and the reference axis 15 finally obtain the detection data of the inner hole. In most cases, it is better to establish the reference axis 15 with the center points of the hole sections 140, 141 close to the first and last ends of the channel 13, so as to ensure that the reference axis 15 is closer to the actual axis of the entire channel 13, so as to ensure better measurement the accuracy. The inner hole detection method of this large workpiece of the present invention utilizes the principle t...

The invention discloses an inner bore detection method with high measurement accuracy and a special detection device. The method is characterized in that two bore sections are selected along a bore path, center points of the two bore sections determine a reference axle line, the deviation of center points of other bore sections of the bore path and the reference axle line is observed, and at last the detection data of the inner bore is obtained. The reference axle line which is determined by using the center points of the two bore sections is used to replace the traditional mandrel, thereby eliminating the measurement error caused by the bending deformation of the mandrel, and greatly improving the measurement accuracy. The center points of the bore sections are determined by the device. The device comprises a supporting frame with a through hole, wherein at least three length adjustable supporting feet and a radically arranged meter rod are arranged on the supporting frame along the peripheral direction of the through hole at intervals, a target is arranged on the through hole, and the meter rod can rotate along the bulleye axis of the target.
Description
technical field [0001] The invention relates to a method and a device for detecting the straightness of the axial center line of the inner hole and the coaxiality of group holes of a large-scale mechanical product during processing and assembly. Background technique [0002] When machining and assembling large-scale mechanical products such as the inner hole of the cylinder and the bearing hole of the support ring, it is necessary to detect the straightness of the axis line and the coaxiality of the group holes. Taking the detection of the straightness of the axis line of the inner hole of a large workpiece as an example, the existing detection methods are as follows: image 3 As shown, a detection device with a relatively long mandrel is used. The test device is equipped with a radially protruding stem on the mandrel and can move axially along the mandrel. The support structures at both ends of the mandrel support the mandrel in the inner hole to be tested, and adjust the s...
