Further improvement as the utility model above-mentioned EFI valve body durability test desk: the guide frame also comprising restriction drag-line position, described guide frame is fixedly connected with cushion block side; Described traction switch block is semicircular structure, and the arcuate flanks of traction switch block is provided with metallic channel.Guide frame can prevent drag-line transverse shifting.Be semicircular structure due to guiding piece and be fixedly connected with the rotating shaft of electric spray valve body examination test specimen air door, the turning radius of rotating shaft is increased, convert the crankmotion of rotating shaft to linear reciprocating motion by drag-line, be convenient to controlled motion stroke, make the angle of door opening more accurate; Because the side of guiding piece is provided with metallic channel, but drag-line is positioned at metallic channel, prevents drag-line landing.
Further improvement as the utility model above-mentioned EFI valve body durability test desk: described locating device comprises briquetting, adjusting bolt and fastening stud, has chute in the middle part of briquetting, fastening stud one end is passed chute and is offseted with fixed station; Adjusting bolt is connected with briquetting, fixed station bolt.Be fixedly connected with fixed station by briquetting by fastening bolt, rotate adjusting bolt, by lever principle, electric spray valve body examination test specimen is tightly pressed on fixed station by briquetting, and structure is simple.
Further improvement as the utility model above-mentioned EFI valve body durability test desk: the stroke of described drive unit is 4.2mm.When 4.2mm is moved in one end that drag-line is connected with drive unit, traction switch block drive under, air door reaches maximum, can detect when air door repeatedly reach maximum after, whether there is the not smooth even stuck state of closing process.
Further improvement as the utility model above-mentioned EFI valve body durability test desk: the air door of described electric spray valve body examination test specimen needs open and close 1,000,000 times.Within engine normal tenure of use, the air door open and close number of times of EFI valve body is far smaller than 1,000,000 times, is detected for 1,000,000 times, can ensure the quality of product further by air door open and close.
Further improvement as the utility model above-mentioned EFI valve body durability test desk: also comprise casing, described casing side is provided with door; Described drive unit is positioned at casing.After adopting such structure, can prevent in use, user of service touches the drive unit of high-speed cruising and causes danger.
