Description

A kind of DQ971, DQ589 section bar special thickness size rapid detection tool
Technical field
A kind of frock is the utility model is related to, more particularly to a kind of DQ971, DQ589 section bar special thickness size is quickly examined Survey frock.
Background technology
Aero-Space DQ971, DQ589 section bar frame parts category structural member, is through Overheating Treatment in space product with section bar Afterwards by special equipment and the ring-shaped work pieces of type tire stretch forming, there is the characteristics of length is different, different.It can divide by name For end frame, half frame, frame etc..Four kinds of 45 degree, 120 degree, 90 degree of central angle and 180 degree, also referred to as 1/8th frames, a quarter Frame and half frame, usual central angle are 180 degree.
Due to the difference of product structure, accessory size is also not quite similar, and still, all kinds of section bar frame parts precision are all to section Final product structure size has vital effect.Special type face thickness precision, flatness, the perpendicularity of part all may be used The overproof of section product can be caused, the measurement accuracy of size is particularly important.But the extremely difficult progress of this special thickness size is accurate Really measurement, testing staff, which holds to exist when common micrometer or segmental support measure, can not ensure measurement position by drawing At height 85mm with the control of the baseplane depth of parallelism.Actual measurement is the measurement to a size point, rather than face or line.Measurement When measurer always with ellipsoid run-off the straight, be unable to reach the angle of drawing requirement, make measurement result that deviation occur, more can not Realize and this size of whole part is detected.Detection efficiency is extremely low, for a long time a never good detection side Method, turn into a bottleneck for restricting general assembly progress, and cannot effectively solve for a long time.
The content of the invention
The purpose of this utility model be that provide a kind of a kind of DQ971 for solving the above-mentioned not high problem of measurement accuracy, DQ589 section bar special thickness size rapid detection tools.
To achieve these goals, the technical solution adopted in the utility model is such:A kind of DQ971, DQ589 section bar Special thickness size rapid detection tool, including height gauge and cutting ferrule, the height gauge include pedestal, chi frame and measuring jaw, also wrapped A U-shaped fixed mount is included, the U-shaped fixed mount is wherein provided with a first vertical screwed hole, first screw thread among a top Close to a horizontal through hole immediately below hole, the through hole is horizontal to run through U-shaped fixed mount, and another top of U-shaped fixed mount is provided with The center line overlap of the second screwed hole that one level runs through, the through hole and the second screwed hole, also set up on the U-shaped fixed mount There is a horizontal connecting rod outwardly, the connecting rod be located at the second screwed hole lower section, by cutting ferrule, connecting rod and measuring jaw by U-shaped Fixed mount is opening down horizontal fixed, in addition to a regulation measurement screw rod, a locking nut and a lock-screw, the regulation are surveyed Amount screw rod passes through through hole, and its one end outwardly is provided with a dial gauge, and the locking nut is threadedly coupled with the first screwed hole, The lock-screw is threadedly coupled with the second screwed hole.
It is further:A diameter of 8mm of the through hole.
It is further:The lock-screw is M5 × 25mm and tail surface is annular knurl processing, the regulation measurement spiral shell Bar is M5 × 50mm, and its head length is 15mm cone cusp, and the centrum cusp is R1 bulbs, the connecting rod chi Very little is 30 × 10 × 9mm.
It is further:The equal rounding angle of eight edges in U-shaped fixed mount bottom.
Compared with prior art, the utility model has the advantage of:Improve detection efficiency:Every product can improve inspection 10 times of efficiency is surveyed, detection time was shortened to 1.5 minutes by 15 minutes.Accuracy of detection is improved, improves 5 times of accuracy of detection, is examined Survey error and 0.01mm is narrowed down to by 0.05mm.It is applied widely, suitable for the such special thickness size of various section bars and spinning class Sheet metal part thickness detects.Device manufacturing cost is low, commonly can reinforced aluminium alloy, material usage is few, clever structure.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment 1:As shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of DQ971, DQ589 section bar special thickness chi of the utility model Very little rapid detection tool, it is made up of five parts, wherein having 5, lock-screws of a U-shaped fixed mount, an adjustable survey Measure screw rod, a locking nut.Lock-screw surface carries out annular knurl processing increase and the friction of hand, by five parts and height gauge 1st, can be used after dial gauge 6 combines.Dial gauge is installed at the through hole 7 with U-shaped fixed mount 5 before part is detected, and with Dial gauge is fixed on U-shaped fixed mount 5 with lock-screw after adjustable measurement screw rod small change, then by U-shaped fixed mount 5 The measuring jaw 4 of connecting rod 10 and height gauge 1, it is fixed with the special cutting ferrule of height gauge, just completes measurer assembling.Recycle high Degree chi 1 is adjusted according to part height position dimension, can be operated with completing detection.U-shaped fixed mount 5 is first processed into 150 × 140 × 20mm rectangular block, for another example figure be processed into the framework of U-shaped, a diameter of 8mm through hole 7 is processed in corresponding position And M5 the first screwed hole 8, and other end is processed to 30 × 10 × 9mm connecting rod 10 and M5 the second screw 9, lock The screw tail surface that screw is processed into M5 × 25mm carries out annular knurl processing, and adjustable measurement screw rod is processed into M5 × 50mm spiral shell Club head length is 15mm cone cusp, and the cone cusp is R1 bulbs;, locking nut is processed into be coordinated with M5 screw rods Nut.
In the above-described embodiment, in order to prevent operating personnel using, take the U-shaped fixed mount 5 when, there is scratch Situation, as preferable mode, the U-shaped fixed mount 5 bottom eight equal rounding angle of edge.
