Specific implementation mode
Providing embodiment below in conjunction with the accompanying drawings, the utility model is described in further detail：
Embodiment：
Refer to Fig. 1, a kind of big screw pitch internal thread quality testing assembly of the utility model, including thread measurement rule 1, main shaft
2, flighted screw 3, helical pitch cup department 4, unidirectional briquetting 5 and shell 6, the flighted screw 3 are provided with through hole, through hole in an axial direction
It is inside equipped with the main shaft 2 that rotation is not interfered, the left end of the main shaft 2 is removably connected with thread measurement rail 1, and right end is connected with spiral shell
Mother 7, nut inside are equipped with the unidirectional briquetting 5 with integrated spindle axis, first are cased on the main shaft between the unidirectional briquetting and nut
Spring 8；The left end of the unidirectional briquetting is equipped with the matched reversed ratchet of positive ratchet with flighted screw right end；
Flighted screw external screw-thread connection helical pitch cup department 4, helical pitch cup department 4 is installed in shell 6, and helical pitch cup department includes path
Portion 9 and large-diameter portion 10, small diameter portion stretch out outside shell, and second spring 11, major diameter are cased on the small diameter portion between large-diameter portion and shell
The left end in portion connects internal jump ring 12, which is stuck in the card slot of the inner wall of shell, by above-mentioned structure design, helical pitch spiral shell
Bar 3 rotates, and since the positive ratchet of flighted screw 3 is matched with the reversed ratchet of the unidirectional briquetting on main shaft 2, makes
It obtains main shaft 2 and drives 1 rotation of thread measurement rule；When thread measurement rule 1 cannot smooth detection screw thread and when forming certain resistance, screw thread
Detection rule 1, which cannot rotate, causes unidirectional briquetting 5 and 3 matched ratchet of flighted screw to skid；When inverted, then unidirectional
Compulsory withdrawal thread measurement is advised under the occlusion of gear；Flighted screw 3 is threadedly coupled with helical pitch cup department 4 and in the limitation of internal jump ring 12
Be installed under effect in shell 6, when thread measurement rule 1 import screw thread have some setbacks when can bullet protection, avoid thread measurement rail roll over
It is disconnected.
The main shaft left end is equipped with the gradual change hole 13 that aperture becomes larger from left to right, the right end in the gradual change hole and a right
The stepped hole 14 that diameter is less than left side diameter is connected to one heart, and a push jack 15 enters across gradual change hole in stepped hole left-hand component, should
The outer surface of push jack is surrounded with ball grooves 16, several balls 17 are equipped between the ball grooves and gradual change hole internal face；It is described to push away
Piece is provided with through hole in an axial direction, and thread measurement rule are equipped in through hole, and the right end radial stop of the thread measurement rail is inserted in
In stepped hole right-hand component；It is cased with a third spring 18 on the thread measurement rule, which only peaks at push jack
The right end of right end, third spring only peaks on the step surface between stepped hole left-hand component and right-hand component, a left side for the push jack
End outer surface is formed with ring-shaped edge 19, and by above-mentioned structure design, the right end radial stop of thread measurement rule 1 is inserted in rank
In terraced hole right-hand component, the radial positioning of thread measurement rail is realized；Push jack 15 by third spring 18 effect so that ball 17
It is only pushed up by 13 inside of gradual change hole of main shaft 2 and holds out against thread measurement rule 1, such thread measurement rule 1 are closely located in main shaft 2
It is interior；When needing to dismantle thread measurement rule 1, pressing ring-shaped edge 19 makes 13 inner wall of gradual change hole and 15 outer wall of push jack of main shaft 2
Between gap increase, ball 17 far from push jack axis direction movement with thread measurement advise loosen, at this time can be easily by screw thread
Detection rule are unloaded.
To sum up, the utility model solves the shortcomings of the prior art by above-mentioned structure design, can be right
The internal thread of big screw pitch carries out thread quality detection, and can prevent thread measurement rail clip extremely in screw thread, additionally it is possible to anti-spin-ended
Turn detection to have some setbacks, and since flighted screw and helical pitch cup department are full thread cooperations, do not limit up and down, can avoid punching machine stroke
Become larger suddenly, detect stroke become larger and the situation that causes detector stuck.
Above-described specific implementation mode, to the purpose of this utility model, technical solution and advantageous effect carried out into
One step is described in detail, it should be understood that the foregoing is merely specific embodiment of the present utility model, is not used to limit
Determine the scope of protection of the utility model, within the spirit and principle of the utility model, any modification for being made equally is replaced
It changes, improve, should be included within the scope of protection of this utility model.
