Problems solved by technology

[0002] The current cylindricity detection for the connecting rod hole is mainly detected by the dial gauge. During the detection process, we must always pay attention to the numerical changes of the dial gauge, and use the micrometer for detection. There is a single sampling point in the sampling point measurement. It is necessary to adjust the position of the micrometer to measure the cylindricity of different apertures each time. It is inconvenient to use, the detection time is long, and the proficiency of the processing personnel is high. Various points, and simple operation, only need to replace the threaded detection head for the detection of different apertures

Embodiment Construction

[0012] Embodiments of the present invention are as figure 1 As shown, the connecting rod hole cylindricity detection device includes: workpiece 1, nut 2, air guide tube 3, air pressure gauge 4, workbench 5, handle 6, screw rod 7, support block 8, and detection head 9.

[0013] Two axial and radial blind holes are processed on the detection head 9. The two blind holes are connected inside the detection head 9. The center line of the radial blind hole is perpendicular to the central axis of the detection head 9. The axis of the detection head 9 The stomata communicate with the trachea 3 .

[0014] Install the support block 8 in the round hole on the workbench 5, process a threaded hole concentric with the workbench hole on the support block 8, screw the screw rod 7 with the handle 6 at the end into the threaded hole of the support block 8 , the end of the screw rod 7 is threadedly connected with the detection head 9, the nut connected with the air duct 3 is threaded with the de...

Abstract

The invention discloses a cylindricity detection device of a connecting rod hole. The device comprises a nut, an air guide tube, a barometer, a working table, a handle, a screw, a supporting block and a detection head, wherein the supporting block is fixedly arranged in a circular hole in the working table and is provided with a threaded hole; the screw, of which the end part is provided with the handle, is screwed into the threaded hole of the supporting block; the end part of the screw is in threaded connection with the detection head; the nut, of which the end part is connected with the air guide tube, is in threaded connection with the detection head; the barometer is arranged between the air guide tube and a constant pressure air station; the detection head is provided with an axial blind hole and a radial blind hole; the two blind holes are communicated in the detection head; the central line of the radial blind hole is perpendicular to the central axis of the detection head; the axial air hole of the detection head is communicated with the air tube; the cylindricity of different apertures can be detected by replacing the detection head; by using the screw feed, sample points can be spirally collected, and the operation is easy.

Description

technical field [0001] The invention relates to a cylindricity detection device of a hole, in particular to a cylindricity detection device of a connecting rod hole. Background technique [0002] The current cylindricity detection for the connecting rod hole is mainly detected by the dial gauge. During the detection process, we must always pay attention to the numerical changes of the dial gauge, and use the micrometer for detection. There is a single sampling point in the sampling point measurement. It is necessary to adjust the position of the micrometer to measure the cylindricity of different apertures each time. It is inconvenient to use, the detection time is long, and the proficiency of the processing personnel is high. Various points, and simple operation, only need to replace the threaded detection head for the detection of different apertures. Contents of the invention [0003] The purpose of the present invention is to change the use of a single micrometer to d...
