Abstract
The invention discloses a measuring method for microscopic height of a thread of an end seal of a workpiece; measurement is finished by the measuring method by adopting a market-available universal feeler gauge and a market-available universal knife straight edge. The measuring method for the microscopic height of the thread of the end seal of the workpiece comprises the following steps: firstly enabling the measuring end of the knife straight edge, i.e. the blade part, to ride on any chord length of concentric circles of the thread of the end seal of the workpiece, wherein a gap is formed between the extension part of the knife straight edge and the sealing face of the workpiece; then, filling the gap with one or more than one feeler gauge with known thickness, and computing a nominal value of known thickness, i.e. the actual measurement dimension of the microscopic height of the concentric circle thread. According to the measuring method disclosed by the invention, by adopting the principles that the gap is formed between the extension part of the knife straight edge and the sealing face of the workpiece, and then, the gap is measured with the feeler gauge, the dimension of the gap is directly measured, and therefore the height of the concentric circle thread is obtained; the knife straight edge and the feeler gauge are both measuring tools; the measuring method is low in cost and flexible.
Description
Technical field
The present invention relates to field of measuring technique, particularly relate to a kind of Work piece sealing mouth tooth form microcosmic height measurement method.
Background technology
To the quality testing of the process of manufacturing in current part industry, be subject to the restriction of Time and place.All sizes not on drawing can simply directly be measured.Microcosmic height be not difficult to directly obtain data by the modernization such as projector, CMM surveying instrument.Work piece sealing mouth concentric circles crest height theoretical value in Fig. 2, Fig. 3 is less than or equal to 0.5mm and directly cannot obtains with general purpose measuring tool.And develop the higher cost of special measurement instrument needs.In Fig. 2, Fig. 3, what the measuring method of concentric circles height was general is adopt first cutting, then to the projection of cutting plane zigzag fashion, then the drop indirect inspection to projection, draw thread height.The large inconvenience of difficulty of checked operation level, care and maintenance workload is large, and production cost is obviously increased.
Summary of the invention
The technical problem to be solved in the present invention, be to provide a kind of Work piece sealing mouth tooth form microcosmic height measurement method, this method utilizes lower cost to complete the measurement of microcosmic height, under the prerequisite ensureing data reliability, improve detection efficiency, reduces the difficulty of checked operation level.General purpose measuring tool is used to maintain easily and maintain, convenient assessment repeatability and repeatability.
The technical scheme adopted is:
A kind of Work piece sealing mouth tooth form microcosmic height measurement method, this measuring method all adopts commercial general clearance gauge and edge of a knife chi to complete measurement.Work piece sealing mouth tooth form microcosmic height measurement method comprises the following steps:
A, ride over the arbitrary chord length of tooth form concentric circles of Work piece sealing mouth with edge of a knife chi measuring junction both blade position, between its extending part and Work piece sealing face, form gap.
B, fill up gap by the known a slice of thickness in clearance gauge or several pieces, the nominal value calculating known thickness is concentric circles tooth form microcosmic height actual, measured dimension.
The present invention adopts between the extending part of edge of a knife chi and Work piece sealing face and forms gap, then measures the principle in gap with clearance gauge, directly records gap size, both concentric circles thread height had been obtained, edge of a knife chi and clearance gauge are general purpose measuring tool, and cost is low, and measuring method is flexible.
Accompanying drawing explanation
Fig. 1 is measuring principle schematic diagram of the present invention.
Fig. 2 is measured workpiece sealing surface concentric circles tooth form structural representation of the present invention.
Fig. 3 is the vertical view of Fig. 2.
Embodiment
A kind of Work piece sealing mouth tooth form microcosmic height measurement method, this measuring method all adopts commercial general clearance gauge 3 and edge of a knife chi 2 to complete measurement.Work piece sealing mouth tooth form microcosmic height measurement method comprises the following steps:
A, ride over the arbitrary chord length of tooth form concentric circles 5 of workpiece 1 seal with edge of a knife chi 2 measuring junction both blade position, between its extending part and workpiece 1 sealing surface, form gap.
B, fill up gap by the known a slice of thickness in clearance gauge 3 or several pieces, the nominal value calculating known thickness is concentric circles tooth form 4 microcosmic height actual, measured dimension.
Edge of a knife chi and clearance gauge are general purpose measuring tool, and measuring method is flexible, as shown in Figure 1.
