Adopt above technical scheme, benchmark flat board is used for Simulated gas cylinder cap, owing to valve mechanism cover having 22 place's planes higher than mould assembling face, therefore, raised face one_to_one corresponding in the groove that benchmark flat board designs or pit and valve mechanism cover, so that when valve mechanism cover tips upside down on benchmark flat board, 22 place's raised faces sink in groove or pit, and mould assembling face and the benchmark planar surface of valve mechanism cover are adjacent to; 18 bolts hole processed by benchmark flat board, the bolt through-hole one_to_one corresponding in each bolt hole and valve mechanism cover.
During detection, valve mechanism cover is tipped upside down on benchmark planar surface, bolt through-hole in valve mechanism cover is aimed at respective screw hole on benchmark flat board, by 18 bolt type inspection pins respectively successively through valve mechanism cover, screw in the bolt hole of benchmark flat board, examine pin by the moment values of the regulation formula that tights a bolt respectively with torque spanner, moment values is 12N.m.Insert to the gap between valve mechanism cover mould assembling face and benchmark flat board with the clearance gauge of thickness 0.3, if can insert, then product plane degree and bolt through-hole position degree can not reach the requirement of product design diagram technology; If can not insert, then product plane degree and bolt through-hole position degree have reached the requirement of product design diagram technology.The time of whole testing process cost is short, and detection efficiency is high, and testing result accurately, reliably.
In order to simplify structure, the lower end of described bolt type inspection pin is screw rod, and middle part is cylinder, the upper end side of being tenon.
Further, the diameter of described bolt type inspection pin middle part cylinder is 10mm.
Further, the square tenon length of side of described bolt type inspection pin upper end is 10mm.
Beneficial effect is: the utility model structure is simple, low cost of manufacture, and carry out flatness detection by Simulated gas cylinder cap to the mould assembling face of valve mechanism cover, detection efficiency is high, and testing result accurately, reliably.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the utility model is made up of benchmark dull and stereotyped 1 and bolt type inspection pin 2.Wherein, benchmark dull and stereotyped 1 is rectangular flat, the front-end and back-end of dull and stereotyped 1 upper face of this benchmark are provided with one and ranked first groove 3, the number that often ranked first groove 3 is six, the first groove 3 being positioned at front end, by through for the front end face of benchmark flat board 1, is positioned at the first groove 3 of rear end by through for the rear end face of benchmark flat board 1.Second groove 4, second groove 4 is provided with by through for the left side of benchmark flat board 1 in the centre position of the dull and stereotyped 1 upper face left part of benchmark.Three the 3rd groove the 5, three grooves 5 are provided with from front to back by through for the right side of benchmark flat board 1 at the right part of dull and stereotyped 1 upper face of benchmark.About two the 4th grooves 6 are side by side provided with at the middle part of dull and stereotyped 1 upper face of benchmark, bolt hole 7 is provided with in the first groove 3, second groove 4, the 3rd groove 5 and the 4th groove 6, the bottom surface of the through benchmark flat board 1 of bolt hole 7, and each bolt hole 7 is all configured with a bolt type inspection pin 2.
