Description

A kind of instrument for being used to detect connecting rod blank forge mould mismatch amount
Technical field
The utility model belongs to a kind of detection instrument of Machining of Connecting Rod, mainly for detection of connecting rod blank
The mismatch amount of forge mould and the mismatch amount of outsourcing connecting rod blank are checked and accepted.
Background technology
Connecting rod is the critical component in engine, and the quality of connecting rod blank part will directly influence connecting rod ASSY in engine The performance of interior work.The manufacture of connecting rod blank, typically all formed using forging forging dies, in forging process, it is desirable to the company of upper mould Bar profile die cavity overlaps with the connecting rod profile die cavity of lower mould, it is desirable to the connecting rod profile die cavity of the connecting rod profile die cavity and lower mould of upper mould Mismatch amount be not more than 0.3mm, and judge that whether the connecting rod profile die cavity of upper mould overlaps with the connecting rod profile die cavity of lower mould, needs to try Connecting rod rough forging blank is detected, and the method for original measurement mismatch amount is first to measure connecting rod one side aperture to connecting rod using slide measure The distance of appearance profile, then another planar survey connecting rod another side aperture is turned to the distance of connecting rod appearance profile, both sides are surveyed The difference that total subtracts each other is more than 0.3mm, then judges that mismatch amount is overproof, less than 0.3mm, then judges that mismatch amount is qualified.According to difference pair Forge mould mismatch amount is modified.This detection method due to the form error by connecting rod appearance profile draft angle and blank hole, The influence of tolerance, measurement error are larger, it is impossible to and it is accurate to judge whether mismatch amount is qualified, often judge by accident unqualified to be qualified, cause Machining of Connecting Rod to during product inspection, more than 0.3mm scrap by connecting rod two sides contours profiles to hole back gauge difference, and detects effect Rate is relatively low, and heavy losses are caused to company.The connecting rod that existing our company monthly produces is up to tens kinds, the connecting rod hair that oneself is forged More than ten of kind of base, more than ten of kind of outsourcing connecting rod blank.Not only to be responsible for detecting the mismatch amount of forge mould, to be also responsible for outsourcing The acceptance test of connecting rod blank, workload is big, is not suitable with the demand produced in enormous quantities.In view of such a reason, it is necessary to connecting rod hair The detection of base forge mould mismatch amount is improved, to adapt to the large-scale production of connecting rod.
Utility model content
The utility model technical issues that need to address and purpose are, according to existing to connecting rod blank forge mould mismatch amount It is insufficient existing for detection, design a kind of new detection connecting rod blank forge mould mismatch
The instrument of amount.Fundamentally overcome the phenomenon that can not accurately judge whether mismatch amount is qualified, detection efficiency is low, reach The accuracy for surveying connecting rod blank forge mould mismatch amount is effectively ensured, improves detection efficiency, reduces cost, adapts to the big rule of connecting rod The demand of mould production.
Main technical schemes of the present utility model:The utility model includes left survey block, right survey block, bolt, nut;Pass through spiral shell Bolt, nut, left survey block and right survey block are coordinated and fixed;The left survey face gradient for surveying block is 40, the right survey face for surveying block is edge of a knife face, The right survey face gradient for surveying block is 40, right survey block
There is a groove on the survey face left side;The angle that left survey block and right survey block after assembling are formed is adjustable by bolt and nut.
The utility model is proved by practical application:Purpose of design is fully achieved, connecting rod blank forging can be accurately measured The number of modeling mismatch amount and direction(It is horizontal and vertical), institute's measured value for connecting rod blank forge mould mismatch amount amendment provide reliably according to According to avoiding the unqualified connecting rod blank of batch and flow into following process, cause batch loss due to spoiled work;Both connecting rod blank forging had been can detect Mould mismatch amount, the measurer examined but also as outsourcing blank;According to the blank die forging gradient of different connecting rods, on adjustment instrument It is left to survey block, the right angle for surveying block, you can the mismatch amount suitable for measuring and examining different connecting rod blanks;Improve three times of detection efficiency More than, in this procedure, production cost substantially reduces, and adapts to the large-scale production of connecting rod completely.

Embodiment
Main technical schemes of the present utility model are illustrated by reference picture 3,4:The utility model includes left survey block 1(See Fig. 6,7), it is right survey block 2(See Fig. 8,9), bolt 3, nut 5;By bolt 3, nut 5, left survey block 1 and right survey block 2 are coordinated solid It is fixed;The left survey face gradient for surveying block 1 is 40(See Fig. 6), the right survey face for surveying block 2 is edge of a knife face (see Fig. 9), and the survey face of right survey block is oblique Spend for 40(See Fig. 8), there is a groove 4 on the right survey face left side for surveying block 2, and (see Fig. 8, this groove is surveyed in block positioned at left and right after assembling The heart, see Fig. 3);Left survey block 1 and right survey block 2 after assembling are formed
Angle E it is adjustable by the nut 5 of bolt 3.
Reference picture 3, the course of work of the present utility model:, according to connecting rod blank requirement draft angle value, pass through bolt The good corresponding angle E of 3 nuts 5 debugging and fixation;, positive neutralization to connecting rod blank microcephaly side is to the small end surface of connecting rod blank Make a temporary marker D at the wall thickness at hole center(See Fig. 1,2);, that connecting rod blank microcephaly side draft angle C is inserted into instrument is left It is right to survey the oblique survey face of block, and blank temporary marker D and instrument groove 4 are aligned, if now the oblique survey face unclarity of block is surveyed in left and right Light, illustrate that horizontal mismatch amount is zero, if bright light is inserted into clearance gauge measurement, the mismatch amount less than 0.3mm is qualified, otherwise big It is unqualified in 0.3mm mismatch amount, it is to be modified that underproof data must be write down;, the small end surface die forging of connecting rod blank is oblique Spend the oblique survey face that C insertion instruments or so survey block(See Fig. 5), and blank temporary marker D and instrument groove 4 are aligned, now or so If surveying the impermeable light in oblique survey face of block, illustrate that longitudinal mismatch amount is zero, if bright light is inserted into clearance gauge measurement, less than 0.3mm Mismatch amount to be qualified, otherwise the mismatch amount more than 0.3mm is unqualified, and it is to be modified must to write down underproof data.
Reference picture 3, the mismatch amount of the connecting rod blank forge mould of different size is detected, only need to be by the draft angle of connecting rod blank It is required that the good corresponding angle E of debugging is i.e. detectable.The draft angle of usual connecting rod blank is in 4--100Between.
Examination of the utility model to outsourcing connecting rod blank mismatch amount, its operation are same as above.Purpose is that rejecting mismatch amount is overproof Connecting rod blank.
The utility model has been used for a variety of connecting rod blank forge moulds such as EG01, EG01T, EA10FF, D18,4G94S4 at present The detection of mismatch amount, have been used for the examination of the mismatch amounts of a variety of outsourcing connecting rod blanks such as BYD473, H16, H15TC, DA471, effect Fruit is preferable.
