A plurality of benchmark positioning contacts are arranged on the right side surface of a gauge stand supporting frame; the plurality of benchmark positioning contacts are positioned at a same horizontal position and the positions of the front ends of the plurality of benchmark positioning contacts are consistent; the radiuses of circular arcs at the end parts of the plurality of benchmark positioning contacts are smaller than 0.3mm; contacts of a dial indicator are arranged on the plurality of benchmark positioning contacts; the radiuses of circular arcs at the end parts of the contacts of the dial indicator are smaller than 0.3mm; the to-be-detected blade is placed on the upper end surface of a benchmark block of a base; the distance from the plurality of benchmark positioning contacts to the lower horizontal surface of the blade to be detected is smaller than 0.3mm; and the distance from the contacts of the dial indicator to the upper horizontal surface of the to-be-detected blade is smaller than 0.3mm. The front surface and the back surface of the to-be-detected blade are placed on the benchmark block respectively and propped against the plurality of benchmark positioning contacts and the readings of the front surface and the back surface of the blade are read from the dial indicator, so that whether the verticalities between the two side surfaces and the horizontal surface of the blade meet design requirements can be judged, the detection is quick and convenient, and the requirements for batch detection in a production field can be met.
Description
Technical field
The utility model belongs to leaf quality detection technique field, specifically relates to a kind of blade plane and lateral vertical side degree and detects anchor clamps.
Background technology
The blade of using in the power-assisted steering pumping system of automobile or steamer, the plane verticality that needs two sides of blade and blade is less than 3 μ m, common verticality detection can be used the verticality detector of state's productions such as Switzerland to move up and down indicating gauge and measure, this verticality detector is used in single-piece or short run or metrological service and checks it is feasible, detecting operation is comparatively loaded down with trivial details, detection speed is slower, can not be adapted to the large batch of detection in production scene.
Summary of the invention
The utility model mainly is to solve above-mentioned existing in prior technology technical matters, provides a kind of blade plane and lateral vertical side degree to detect anchor clamps.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of blade plane and lateral vertical side degree detect anchor clamps, comprise base, described base is provided with the gauge stand support, be fixed with clock gauge on the gauge stand support, gauge stand support right flank is provided with several benchmark positioning contacts, this benchmark positioning contact is in same horizontal level and its front position unanimity, there is circular arc benchmark positioning contact end, and the radius of this circular arc is less than 0.3mm, the contact of clock gauge be arranged on the benchmark positioning contact above, the contact end of clock gauge also has circular arc, and the radius of this circular arc is less than 0.3mm; The right side of gauge stand support, on base, be provided with reference block, put blade to be measured on the upper surface of reference block, the contact of benchmark positioning contact and clock gauge is all suitable with the side of blade to be measured, and less than 0.3mm, the distance on the contact of clock gauge plane to the blade to be measured is less than 0.3mm to the distance of blade lower plane to be measured for the benchmark positioning contact.
The principle that the utility model detects two sides of blade and blade plane verticality is: the thickness of supposition blade is 10mm, verticality requires 0.003, the actual distance of surveying is 10-0.6=9.4mm, as requested, the value that can calculate the verticality in the measurement range is 0.003 ÷, 10 * 9.4=0.00282.
Detect the reading value of clock gauge: detecting reading value according to the verticality pros and cons is 2 times principle, and its deviation at clock gauge is 0.00282 * 2=0.00546mm.Around this principle, the difference of reading at clock gauge blade pros and cons is no more than the requirement that 0.005mm just can guarantee verticality 0.003mm.
Like this as long as be seated in the reference block last time respectively with blade to be measured is positive and negative, and by being located on the benchmark positioning contact, on clock gauge, read the reading of leave dual sides and can judge whether the verticality of two sides of blade and blade plane meets design requirement, detect quick and convenient, can satisfy the demand of the mass detection of production scene, have characteristics such as simple in structure, reasonable in design.
