Technical Field

The invention relates to the technical field of detection measuring tools, in particular to a measuring tool for conical surface runout of a seat ring of an engine cylinder cover.

Background

Each cylinder of the engine cylinder is provided with at least one air inlet valve and at least one air outlet valve, and each valve seat ring is provided with an inner cone and an outer cone which form two angles. The single-sided angle of the outer conical surface of the cylinder head seat ring is generally 60-70 degrees, the single-sided angle of the inner conical surface is generally 30-60 degrees, and at least 4 sets of special measuring tools are needed for measuring the runout quantity of the conical surface of one cylinder seat ring. The detection cost is high, and the operation is complicated. Aiming at the problems in the prior art, the conical surface runout measuring tool for the engine cylinder head seat ring is provided.

Disclosure of Invention

The invention provides a measuring tool for the conical surface runout of a seat ring of an engine cylinder head, aiming at the problems in the prior art, and the measuring tool is realized by the following technical scheme:

the utility model provides an engine cylinder head seat circle conical surface measuring tool that beats, includes the volume body, one end fixedly connected with locating lever on the measuring tool body lateral wall, the solid fixed cylinder of fixedly connected with on the concrete lateral wall of volume, be provided with the amesdial in the solid fixed cylinder, threaded connection has the fastening screw who is used for fixed amesdial on the solid fixed cylinder lateral wall, the gauge head of amesdial passes the volume body and outstanding in the concrete lateral wall of volume, the gauge head and the concrete clearance fit of volume of amesdial, the axis of gauge head intersects with the axis of locating lever, the axis of gauge head and the contained angle between the locating lever axis are 60.

The invention is further configured to: the one end fixedly connected with handle that the locating lever was kept away from specifically to the volume.

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).
