Abstract
Disclosed in the utility model is a measuring scale for a center distance. The measuring scale comprises a measurement rack; a measurement rack transverse shaft is installed transversally on the measurement rack, wherein the measurement rack and the measurement rack transverse shaft are connected by a sliding way. In addition, a bore dial indicator replaceable measuring head is installed at the lower end of the measurement rack; a bore dial indicator and an indicator rod are connected to one end of the measurement rack transverse shaft by a fastening block; and a measuring head is installed at the lower end of the indicator rod. Compared with the existing measuring technology, the provided technology employed by the utility model enables the measuring scale to have the following advantages: the manufacturing is simple; the usage of the scale is convenient; the measurement is accurate; the measurement time is short; and the invested cost on the measuring device is reduced.
Description
Technical field
The utility model relates to a kind of test measuring device, relates to specifically a kind of neither centre distance scale of the detection of phase through hole centre distance of parts that is applicable to, and belongs to checking measurements device technique field.
Background technology
The method of the two hole centre distance sizes that do not communicate that present measuring accuracy is had relatively high expectations, survey Centigrade scale, three-coordinates measuring machine etc. in general the employing, in the actual production testing process, the use of interior survey Centigrade scale has certain limitation, and three-coordinates measuring machine belongs to large-scale measuring equipment, can only measure as the affirmation in the sampling observation process and use, the scene that can't be applied to is measured at any time.
The utility model content
It is simple that problem to be solved in the utility model provides a kind of making, easy to operate, and accuracy of detection requires the centre distance scale of the higher two hole centre distance sizes that do not communicate accurately and fast.
In order to address the above problem, the technical solution adopted in the utility model is:
A kind of centre distance scale, comprise measurement bay, a measurement bay transverse axis laterally is installed on the measurement bay, be slidingly connected between measurement bay and the measurement bay transverse axis, the lower end of measurement bay is equipped with a dial bore gage test probe replaceable, one end of measurement bay transverse axis is connected with dial bore gage and table bar by fastening block, and the lower end of table bar is equipped with gauge head.
Below be the utility model for further improvement of these options:
Measurement bay be equipped with can fastening measurement bay transverse axis hexagon head bolt.
Further improve: test probe replaceable is fastened on the measurement bay by the test probe replaceable clamp nut.
Distance between test probe replaceable and the gauge head of table below the bar deducts the radius value of two measured holes again, namely is the centre distance size that will measure.Using method with inside diameter caliper during use is consistent, constantly slides in the hole by two gauge heads, seeks minimum point, reads the amount of deflection by the dial gauge that the table bar is ined succession.
According to the centre distance size, make different measurement bays, can realize the measurement of multiple centre distance size.
The utility model is compared present measuring technique: make simple, easy to use, measure accurately, Measuring Time is short, reduces the input cost of measurement mechanism.
Below in conjunction with drawings and Examples the utility model is described further.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model embodiment.
Among the figure: the 1-cross recessed small pan head screw; The 2-fastening block; 3-shows bar; The 31-dial bore gage; The 4-gauge head; The 5-hexagon head bolt; The 6-measurement bay; 7-measurement bay transverse axis; 8-test probe replaceable clamp nut; 9-dial bore gage test probe replaceable.
Embodiment
Embodiment, as shown in Figure 1, a kind of centre distance scale, comprise measurement bay 6, a measurement bay transverse axis 7 laterally is installed on the measurement bay 6, is slidingly connected between measurement bay 6 and the measurement bay transverse axis 7, measurement bay 6 be equipped with can fastening measurement bay transverse axis 7 hexagon head bolt 5.
The lower end of measurement bay 6 is equipped with a dial bore gage test probe replaceable 9, and test probe replaceable 9 is fastened on the measurement bay 6 by test probe replaceable clamp nut 8, is convenient to change.
One end of measurement bay transverse axis 7 is connected with dial bore gage 31 and table bar 3 by fastening block 2, and the lower end of table bar 3 is equipped with gauge head 4.
The junction of fastening block 2 and measurement bay 6 all has semicircle orifice, and dial bore gage 31 and table bar 3 pass from the hole.
Fastening block 2, measurement bay 6 are connected with dial bore gage and are shown bar 3 and connect by cross recessed small pan head screw 1 and tighten together.
Distance L between the gauge head 4 below test probe replaceable 9 and the table bar 3 deducts the radius value of two measured holes again, namely is the centre distance size that will measure.Using method with inside diameter caliper during use is consistent, constantly slides in the hole by two gauge heads, seeks minimum point, reads the amount of deflection by the dial gauge that table bar 3 is ined succession.
The dial bore gage head can be made into the clock gauge head during use, just can measure the error that is accurate to thousand minutes positions.
The measurement bay effect is to expand gauge head of inside diameter caliper, adds wide-measuring range.To pass through a ring standard gauge calibration before using, in order to guarantee to realize in the production scene requirement of the accurate measurement of centre distance error.
The utility model measuring center is simple apart from method, do not need pick-up unit is dropped into very large cost, can be accurate in the production line measurement centre distance error of thousand minutes positions, and can realize that the pitch-row in same plane is not measured by changing measurement bay.
