In a preferred embodiment of the present invention, nonstandard product height measuring jig further comprises that described mark post is expansion link.
In a preferred embodiment of the present invention, nonstandard product height measuring jig further comprises that described mark post is cylindrical, and described vertical rod has strip hole along its length, and described mark post is fixed through described strip hole and described vertical rod.
In a preferred embodiment of the present invention, nonstandard product height measuring jig further comprises that described mark post is provided with external thread, and described mark post is fixed in described vertical rod by pad, nut.
In a preferred embodiment of the present invention, nonstandard product height measuring jig further comprises that the lower end of described vertical rod is cylindric, rotating being arranged in described base in lower end of described vertical rod.
In a preferred embodiment of the present invention, nonstandard product height measuring jig further comprises in described vertical rod the pilot lamp that is fixed with controller, is connected with described controller, the lower end of described tooth bar is fixed with pressure transducer, described pressure transducer is connected with described controller, and the bottom of described pressure transducer flushes with the bottom of described tooth bar.
The invention solves the defect existing in background technology, the present invention is simple in structure, easy to use, realizes the height of the irregular product of difference is measured, and measures accurately, and work efficiency is high.

Embodiment
The present invention is further detailed explanation in conjunction with the accompanying drawings and embodiments now, and these accompanying drawings are the schematic diagram of simplification, and basic structure of the present invention is only described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As Fig. 1, shown in Fig. 2, a kind of nonstandard product height measuring jig, comprise base 2, be arranged on the vertical rod 4 on base 2, in vertical rod 4, be carved with master calibration 6, in vertical rod 4, be horizontally installed with mark post 8, mark post 8 moves up and down along vertical rod 4, on mark post 8, be fixed with index dial 10, be positioned at the cylinder assembly in index dial 10 outsides, index dial 10 is provided with scale division 12, index dial 10 center is equipped with fulcrum 14, one end of fulcrum 14 is fixed with pointer 16, the other end is fixed with gear 18, cylinder assembly comprises riser 20, be fixed on the cylinder 22 on riser 20, the horizon bar 26 being connected with the cylinder arm 24 of cylinder 22, one end of horizon bar 26 is fixed with the tooth bar 28 of vertical setting, tooth bar 28 engages with gear 18, moving up and down driven gear 18 by tooth bar 28 rotates, thereby pointer 16 is rotated, the scale division 12 of diverse location on indication dial disc 10, thereby draw reading from index dial 10.
The preferred mark post 8 of the present invention is expansion link, and mark post 8 can move left and right by along continuous straight runs, is convenient to drive index dial 10, cylinder 22 integral left to move right, and be convenient to the measurement to different recess height, and without mobile product, time saving and energy saving, work efficiency is high.Move up and down for the ease of mark post 8, realize the measurement of the product to differing heights, increase the scope of application, as shown in Figure 3, the preferred mark post 8 of the present invention is cylindrical, and vertical rod 4 has strip hole 30 along its length, mark post 8 is provided with external thread 32, mark post 8 passes strip hole 30 and is fixed in vertical rod 4 by pad 34, nut 36, and in the time of the mobile mark post 8 of needs, only need unclamp nut 36 is adjustable mark post 8.
In order to be better suitable for nonstandard product, avoid customizing multiple survey instruments, reduce the production cost of enterprise, the lower end of the preferred vertical rod 4 of the present invention is cylindric, rotating being arranged in base 2 in lower end of vertical rod 4.
The pilot lamp 40 that is fixed with controller 38 in the preferred vertical rod 4 of the present invention, is connected with controller 38, the lower end of tooth bar 28 is fixed with pressure transducer 42, pressure transducer 42 is connected with controller 38, the bottom of pressure transducer 42 flushes with the bottom of tooth bar 28, when preset value in the force value that pressure transducer 42 is responded to reaches controller 38, shows that tooth bar 28 reaches measurement point, now, pilot lamp 40 is bright, and alert is cut off the action of cylinder 22, measures precisely.
The present invention in use, first the bottom of mark post 8 is flushed with the most significant end of product 44, record height value h1 now by the master calibration 6 in vertical rod 4, then, Level tune mark post 8, to there being recess to move, mark post 8 is located, and starts cylinder 22, and cylinder arm 24 is with carry-over bar 28 to move downward to contacting with depression diapire by horizon bar 26, after pilot lamp 40 is bright, cylinder 22 stops action, now sees the scale division 12 that pointer 16 is indicated, and draws reading h2, now, recess diapire is to the height h3=h1-h2 of base 2.
Be enlightenment according to desirable embodiment of the present invention above, by above-mentioned description, related personnel can, not departing from the scope of this invention technological thought, carry out various change and amendment completely.The technical scope of this invention is not limited to the content on instructions, must determine technical scope according to claim scope.
