Specific embodiment
Embodiments of the present invention are described further with reference to the accompanying drawing.
The specific embodiment of coupling nut locking pit depth detecting tool of the invention, as shown in Figures 2 to 11.First
Introduce testing principle of the invention, it is as shown in Figure 2 by bail 3 after three crank slots 2 expansion in nut body 1 in three crank slots
Running track schematic diagram, as seen from Figure 2, the locking pit 4 of coupling nut is common by the end of three crank slots and bail hole
It constitutes, as seen from Figure 2, which is located at the side towards the electric connector where bail 3 of three crank slots, 2 end
On side wall, after bail 3 is caught in the locking pit 4, bail and coupling nut can not voluntarily rotate disengaging.Set coupling nut rotation
When entering bail, the location of coupling nut is minimum point B when bail is embedded in the locking pit 4, when coupling nut is by bail
When back-out, coupling nut is mobile towards the direction of the electric connector where bail first, makes bail by the locking pit of coupling nut
Interior abjection, later, the direction that coupling nut faces away from the electric connector where bail screw out, in the present embodiment, setting connection
The location of coupling nut is highest point A when nut alters course, then the difference t between minimum point B and highest point A is as locked recessed
The depth dimensions in hole 4.
The detecting tool in the present invention is devised based on above-mentioned principle, and in the present embodiment, left end is rear end, right end in figure
For front end, i.e. left and right directions corresponds to rear front direction.Detecting tool of the invention includes slide rule component 5 and coupling nut installation part
6.Slide rule component 5 includes pedestal 51, and guiding movement is equipped with sliding ruler 52 in left-right direction on pedestal 51, slides ruler 52 in base
It can be moved left and right on seat 51, the slippage of sliding ruler 52 can be shown by display 53, and display 53 has the function of resetting.
Display 53, pedestal 51 and sliding ruler 52 are unified entirety, and threaded hole 54 is also provided in the left lateral sides of pedestal 51.
Coupling nut installation part 6 includes supporter 61, and supporter 61 is used to be sleeved on for coupling nut 7, when detection, even
Nut 7 is connect to be screwed in by the left end forward direction of supporter 61.The left end of supporter 61 is provided with washer installation part 66, it can be with by Fig. 8
Find out, washer installation part 66 includes the path section positioned at the major diameter section of left end and positioned at right end, and wherein the right end of path section opens up
There is external screw thread, 66 screw thread spinning of washer installation part enters in the left end end face of supporting element 61.Pushing tow is housed in the outer cover of path section
Pressure spring 64 is pressed between the left end end face of washer 65, pushing tow washer 65 and supporter 61.Meanwhile the major diameter of washer installation part 66
Block step is formd between section and path section, for preventing pushing tow washer 65 from being deviate from by the left end of washer installation part 66.
There are three bails 63, three 63 radially protrudings of bail to be arranged in supporter for circumferentially spaced arrangement on supporter 61
On 61.In the present embodiment, the section of supporter 61 is L shape, forms in the upper right corner of supporter 61 and protrudes into for sliding ruler 52
Allow bit space.It is fixed with mounting plate 62 on the right end end face of supporter 61, mounting hole, convenient and base are offered on mounting plate 62
Seat 51 is fixedly linked.
In use, passing through the mounting hole on mounting plate 62 with screw 9 and penetrating in the threaded hole of pedestal 51, by coupling nut
Installation part and slide rule component are combined and installed together, and form detecting tool.
It is of the invention use process is as follows: 1) screw in coupling nut 7 to be measured is positive from left to right on test fixture, even
The interior step for connecing nut 7 pushes pushing tow washer 65 to move right, while compression press spring 64, and three bails correspondence of supporting element is fallen into
In three crank slots of coupling nut 7, after bail drops into the locking pit of coupling nut, the elastic force to the left of pressure spring can guarantee
Bail on supporting element is bonded closely with locking pit.2) sliding ruler 52 is moved to the left, so that the screw-in on the right side of coupling nut
End end face 8 is in contact with the left end side for sliding ruler 52, and after pressing the reset key on display at this time, display 53 is shown at this time
Data be 0.3) coupling nut is slowly returned it is stubborn, due to locking pit presence meeting so that coupling nut push slide ruler to the right
It is separated after movement a distance with sliding ruler, the full-scale reading that display is shown at this time is to lock the size of pit.
It can be first mobile towards the electric connector where bail when reversely being screwed out on as bail using coupling nut in the present invention
Characteristic mobile towards the direction far from the electric connector where bail again after certain distance, the rear end face for sliding ruler 52 is positioned
It presses against on the end face of coupling nut, locking pit minimum point and highest is measured by the maximum moving distance of measurement sliding ruler
Difference between point locks the depth dimensions of pit.Meanwhile being acted on by the press of pressure spring and washer, make coupling nut
Locking pit and bail are in the state fitted closely, guarantee the accuracy measured in whole process.
In the present invention, it is provided with three locking pits on three bails, with coupling nut on supporting element and corresponds, this
The size for the locking pit measured in embodiment is the average-size of three locking pits.When needing to measure, some locking is recessed
When the specific size in hole, it is only necessary to three bails on pedestal are changed to a bail, bail is made to screw in locking pit to be measured
It is interior.
In the present embodiment, sliding ruler is sliding part, and the left end end face of sliding part is pushing tow datum level.In the present embodiment
Display have distance measurement function, constitute measurement structure.In other embodiments, measurement structure may include on sliding part
Scale on cue mark and pedestal is surveyed by reading when sliding part is in scale corresponding to different location cue mark
Measure the sliding distance of sliding part.
Display in the present embodiment has the function of resetting, in other embodiments, when display can not be zeroed out
When, it is only necessary to numerical value when record sliding measuring piece is in different location is subtracted each other again.
In the present embodiment, between pedestal and supporting element by screw realize it is removable be connected, different connection spiral shells can be directed to
Cap chooses different supporting elements, realizes fast quick-detach, increases the use scope of pedestal and sliding part.
In the present embodiment, pressure spring and pushing tow washer constitute elastic top selection structure, in other embodiments, elastic pushing tow
Structure can be other structures, such as elastic rubber.
In the present embodiment, the pushing tow datum level of sliding part is the datum level with the direct pushing tow cooperation of coupling nut, at other
In embodiment, other transition pieces can also be set between sliding part and connection swivel nut, for example, when sliding part leans on front end
When, transition extension is set therebetween, at this point, the pushing tow datum level of sliding part is and the indirect pushing tow cooperation of coupling nut
Datum level.
It can be realized in the above embodiments by the way that elastic top selection structure is arranged and lock pit and bail in coupling nut
In other embodiments cue mark can be arranged in supporting element in automatically lock, i.e., when connection swivel nut forward direction is screwed in indicateing arm
The position clocked is the position for connecting swivel nut and rotating forward locking.
The specific embodiment of coupling nut of the present invention locking pit depth detection method, in detection method and above-described embodiment
Detecting step it is consistent, content repeats no more.
