Abstract

The utility model relates to a metal machining part, in particular to a large-size part with measuring range exceeding that of a common measuring tool. A series of process bosses are machined on the surface of the large-size part, auxiliary measurement datum planes are machined at two sides of the process bosses, are parallel to the end surface of the part and are vertical to the measuring direction, and the distance of the auxiliary measurement datum planes between the adjacent process bosses is less than the measuring range of a vernier caliper for a single person. The large-size part has simple structure, the using performance of the parts is not affected, the vernier caliper for a single person can be utilized to operate by one person, and the measuring value smaller than millimeter can be measured.

Description

The large-scale part of band measuring basis
Technical field
The utility model relates to a kind of metal machined part, particularly exceed measurer measurement range commonly used large-scale part.
Background technology
Traditional metal machined part adopts steel tape, vernier caliper or special-purpose length measurer to measure usually.Though steel tape can directly be measured length, measure the error of indication at 1 millimeter, can not accurately measure the following value of millimeter, the result of measurement is not a true value, and measuring accuracy is lower, and inapplicable measurement error in length has the part of decimal.Vernier caliper is a kind of common measurer commonly used; Indicating value has 0.02 millimeter, 0.05 millimeter, 0.10 millimeter, and wide range vernier caliper specification limit has 1500 millimeters, 2000 millimeters, energy measurement not just when exceeding more than 2000 millimeters.Because big, the quality of wide range vernier caliper volume is heavy, people measures the fixing very difficult levelling row of measuring jaw and movable measuring jaw, must two people's synchronous operations.People's support fixation measuring jaw, another people's adjustment activity measuring jaw.Can cause two people's measurement insensitive like this, dynamometry is inconsistent, and survey measurements there are differences each time, and measuring error is big.Special-purpose length measurer is a kind of measurement relatively, does not have reading; Whether qualified the manufacturing of special sizing can not be adjusted measurement range, be a kind of synthetic determination measuring method.For large-sized special-purpose length measurer, make, the amount face grinds, use keeping all compare difficulty, be out of shape greatlyyer naturally, need two people's synchronous operations equally, a people can't go to measure.
Though high-precision large scale photoelectric measurement instrument has been arranged at present, because cost is higher, measure and take care of difficulty, therefore common machine work enterprise all adopts.
Summary of the invention
The purpose of this utility model is to provide a kind of large-scale part with measuring basis, and it is simple in structure, can utilize measurement range at 1000 millimeters, 0.02 millimeter vernier caliper commonly used of indicating value; Can a people operate, measure the following value of millimeter.
Technical matters of the present utility model is achieved through the following technical solutions: the surface working along part has the series of process boss, the both sides of false boss are processed with the subsidiary reference field, the subsidiary reference field is parallel with the end face of part, and simultaneously vertical with direction of measurement, and the distance of the subsidiary reference field between two adjacent false bosses is less than single range with vernier caliper.
The roughness of the subsidiary reference field of each false boss is 3.2, and the depth of parallelism is 0.08; Distance between adjacent subsidiary reference field is in 1000mm.
The beneficial effects of the utility model: by increasing false boss at piece surface, do not influence the usability of part, but can save and use wide range vernier caliper or special-purpose length measurer, the measuring method that follows conventional lines just can measure the following value of millimeter of large-scale part more exactly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: end face 1, subsidiary reference field 2, longitudinal axis 3, subsidiary reference field 4, false boss 5.
Embodiment
Referring to Fig. 1, surface working along the long size parts of tubulose has series of process boss 5, the both sides of false boss 5 are subsidiary reference field 2,4 by being machined to, subsidiary reference field 2,4 is parallel with the end face 1 of part, and it is simultaneously vertical with the longitudinal axis 3 of direction of measurement, the distance of the subsidiary reference field 2,4 between two adjacent false bosses 5 should be controlled in 1000 millimeters usually less than single range with vernier caliper.When measuring this part length overall, only need accurately measure the actual measurement size between each adjacent measurement face respectively, each section actual measurement size is added up just can accurately be measured numerical value then.

Claims (2)

1. large-scale part with measuring basis, it is characterized in that: the surface working along part has the series of process boss, the both sides of false boss are processed with the subsidiary reference field, the subsidiary reference field is parallel with the end face of part, and simultaneously vertical with direction of measurement, and the distance of the subsidiary reference field between two adjacent false bosses is less than single range with vernier caliper.
2. by the large-scale part of the described band measuring basis of claim 1, it is characterized in that: the roughness of the subsidiary reference field of each false boss is 3.2, and the depth of parallelism is 0.08, and the distance between adjacent subsidiary reference field is in 1000mm.
