Abstract
The utility model provides a surface machining positioning mechanism for engine box part blanks, which comprises a positioning block, a gas detection guiding rod, a spring, a positioning block base and a clamp. The gas detection guiding rod is assembled into a gas detection channel at the edge of the positioning block on the positioning block base in a clearance fit manner, the spring is supported at the lower end of the gas detection guiding rod, a gas detection port is arranged at the position, which corresponds to the lower end of the gas detection guiding rod, of the clamp, and compressed air is connected with a gas pressure monitor by the gas detection port. The length of the gas detection guiding rod is 0.01mm-0.05mm smaller than the height from the bottom surface of the positioning block base to the top surface of a positioned surface, the gas detection guiding rod is supported by spring force in a normal non-operating state with the top end higher than the positioning block by one millimeter. The surface positioning mechanism is compact in structure and high in positioning precision, is simple, practical and reliable, does not increase equipment failure rate, effectively solves the problem of unreliability in positioning of blanks in a traditional process, and improves machining yield.
Description
Technical field
The utility model belongs to engine housing class part machine and adds the location frock, is specifically related to box parts blank machine overstriking positioning fixtures such as engine cylinder cover, cylinder body, case of transmission.
Background technology
Traditional engine housing class part blank adds when location at machine, generally adopt locating surface to tint after with the blank parts fixation to anchor clamps, clamp and then the pine folder, take off the blank part and observe the blank anchor point and have or not the location bright spot to judge whether blank locatees reliably.During actual production for raising the efficiency, generally be to adopt man-hour this way to adjust the location to adding with a collection of blank initial workpiece, but because the blank dimension tolerance is big, and surface quality is generally poor, might be in process cause that blank processing is crooked, benchmark processing is inaccurate because the location is unreliable, coarse positioning precision control difficulty, processing vibrations, the unequal problem of postorder allowance, there is potential risk in product quality.
Summary of the invention
The purpose of this utility model provides a kind of engine housing class part blank machine rational in infrastructure, convenient mounting and clamping and adds the airtight checkout gear of location, solves the insecure problem in location in the blank process, and realizes effective airtight detection alarm monitoring.
The technical solution of the utility model is as follows:
A kind of engine housing class part blank face machine adds location mechanism, and it comprises locating piece, gas inspection guide post, spring, gas inspection mouth, locating piece base and clamp body.Described locating piece base is contained on the clamp body, and locating piece is positioned at locating piece base top; Described gas inspection guide post adopts matched in clearance to be assembled in the gas inspection passage of locating piece side on the locating piece base, and spring is supported on the lower end of gas inspection guide post, and gas inspection guide post slides in gas inspection passage by spring; Gas inspection mouth is opened in position in clamp body correspondence gas inspection guide post bottom, and compressed air is connected with the air pressure monitor by gas inspection mouth.
The length of described gas inspection guide post should be less than the height 0.01-0.05mm from the locating piece base end face to the locating surface end face; And gas inspection guide post is supported by spring force at ordinary times under the off position, and gas inspection guide post top exceeds 1 millimeter than locating piece.
The gas inspection guide post of this detent mechanism is supported by spring force at ordinary times under the off position, gas inspection guide post top exceeds 1 millimeter than locating piece, compressed air is by gas inspection mouth and extraneous the connection, the pressure of this moment is 0pa, when the coarse positioning face of blank part is fallen on the locating piece, the coarse positioning face is depressed gas inspection guide post simultaneously, fit in the gentle inspection guide post of positioning seat lower end, this moment, the anchor clamps inner air pressure rose, after the detected gas pressure of Pressure monitoring instrument reaches the pressure limit of setting, illustrate that blank coarse positioning face and locating piece applying tightness degree have reached technological requirement, system provides signal, the beginning machining.
The utility model also can be adjusted locating surface applying tightness degree by the monitor force scope of adjusting the air pressure detector, and raising equipment starts rate in the scope of technology permission, reduces the generation of waste product.
This mechanism reasonably gathers together by simple parts, is integrated at last on the clamp body, and compact conformation, simple and practical, can not increase equipment failure rate, the positioning accuracy height; The location is reliable; The location is convenient, has effectively solved in the traditional handicraft blank and has located insecure problem, and the raising machine adds yields.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
The specific embodiment
Comprise parts such as locating piece 1, gas inspection guide post 6, spring 5, locating piece base 2, clamp body 3 referring to this black skin of Fig. 1 detent mechanism.
Gas inspection guide post 6 adopts matched in clearance to be assembled in the gas inspection passage of locating piece 1 side on the locating piece base 2, spring 5 supports gas inspection guide post 6 lower ends, on the position of clamp body 3 corresponding gas inspection guide posts 6 lower surfaces, open gas inspection mouth 4, compressed air is connected with the air pressure monitor by gas inspection mouthfuls 4, after blank part 7 coarse positioning faces are fallen on the locating piece 1, depress gas inspection guide post 6 simultaneously, make gas inspection mouthful 4 applyings on gas inspection guide post 6 bottoms and the clamp body 3, the air pressure monitor instrument judges by the compressed air pressure size whether part fits closely with locating piece.
Gas inspection guide post 6 is adjusted with locating piece 1: gas inspection guide post 6 length should be less than the height 0.01-0.05mm from locating piece base 2 bottom surfaces to locating surface 1 end face, prevents that part to be processed from not fitting locating piece and locate with guide post.The anchor point size guarantees positioning accuracy by the technological requirement accuracy Design.Debug gas inspection guide post again and guarantee airtight accuracy of detection.
Gas inspection guide post 6 and locating piece 1 distance determine that according to different product assurance is that the coarse positioning face while and the locating piece 1 gas inspection guide post 6 of processed blank part fitted.
