Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Examples
As shown in fig. 1-2, the engine cylinder head race conical surface runout measuring tool disclosed by the invention comprises a measuring body 1, wherein a positioning rod 2 is fixedly connected to one end of a side wall of the measuring body 1, a fixed cylinder 3 is fixedly connected to the side wall of the measuring body 1, a dial indicator 4 is arranged in the fixed cylinder 3, a fastening screw 5 for fixing the dial indicator 4 is connected to the side wall of the fixed cylinder 3 in a threaded manner, a measuring head of the dial indicator 4 penetrates through the measuring body 1 and protrudes out of the side wall of the measuring body 1, the measuring head of the dial indicator 4 is in clearance fit with the measuring body 1, the axis of the measuring head is intersected with the axis of the positioning rod 2, and an included angle between the axis of the measuring head and the axis of the positioning rod 2 is 60 degrees (in combination with practical application, the single-sided angle of the cylinder head external conical surface is generally 60-70 degrees, so that α is 60 degrees to be suitable for angle measurement of common conical surfaces). When the conical surface of the cylinder cover seat ring is measured, the positioning rod 2 is inserted into a guide pipe hole of the cylinder cover seat ring, a measuring head of the dial indicator 4 is in contact with the conical surface of the cylinder cover seat ring, the dial indicator 4 rotates for 360 degrees to measure the body 1, and the dial indicator 4 displays the jumping amount of the measured conical surface relative to the middle axis. The one end fixedly connected with handle 6 that the locating lever 2 was kept away from to the volume body 1. The turning of the dosing body 1 is facilitated by means of a handle 6.
The specific working principle of the embodiment is as follows:
during measurement, the bottom surface of the measured cylinder cover faces upwards, the whole measuring tool is placed in the measured cylinder cover seat ring, the positioning rod is inserted into a guide pipe hole of the cylinder cover seat ring, a measuring head of the dial indicator is in conical surface contact with the cylinder cover seat ring, and a detector can rotate the measuring tool through the handle to read out a jumping value according to the change of the dial indicator in the rotation process. As shown in fig. 3-4, the included angle between the axis of the probe of the dial gauge and the axis of the valve cover race guide tube is set to α (i.e., 60 °), and the included angle between the taper surface and the axis of the guide tube is measured to determine β, so that the measured taper surface run-out amount is the dial gauge display value/cos (90 ° - α - β) or the dial gauge display value/cos (30 ° - β).
