Embodiment
The core of the present invention is to provide a kind of welded nut position degree error measuring means, and it can detect the spiral shell after welding
Female positional precision, supported so as to provide data for nut location adjustment, ensure the assembly precision of associated components.
In order that those skilled in the art more fully understands technical scheme, below in conjunction with accompanying drawing to this hair
It is bright to be further detailed.
Fig. 1-Fig. 3 is refer to, Fig. 1 is a kind of structural representation of embodiment of detection means provided by the present invention
Figure；Fig. 2 is test pin and structural representation during in running order guide in detection means shown in Fig. 1；Fig. 3 is shown in Fig. 1
The structural representation of test pin in detection means.
In a kind of embodiment, welded nut position degree error measuring means 100 provided by the present invention include
The pedestal 5 of cubing body 0 is fixed in, the pedestal 5 is rotatablely equipped with installing plate 3 by rotary shaft 9；The axle of the rotary shaft 9
Perpendicular to the axis of nut 8 to be detected, the installing plate 3 rotates simultaneously close or remote described to be checked line around the rotary shaft 9
When surveying the product 7 at the place of nut 8, and being located at detection state, the surface of the installing plate 3 and the product 7 fits；The peace
When guide 2 is provided with loading board 3, and being located at detection state, the center of guide 2 and the theoretical welding position center of nut to be detected
Coaxially, test pin 1 passes through the guide 2, and is sheathed on the inner ring of guide 2, the screw thread of the test pin 1 with its cylindrical section 11
Section 12 is screwed with the nut 8 to be detected；Detection datum line 21 is provided with the guide 2.
In order to improve detection convenience, detection datum line 21 can be provided with the outer face of guide 2；Further,
The detection datum line 21 includes horizontal datum and vertical datum line, can be by detecting test pin 1 and the end of guide 2 in detection
The deviation of coordinate system groove (coordinate system that i.e. horizontal datum and vertical datum line are formed) opening position on face, detection draw inspection
The deviation of pin 1 in a coordinate system is surveyed, the deviation of nut 8 to be detected in a coordinate system is that is to say, to improve accuracy of detection.Obviously
Ground, detection datum line 21 can also be the form of graduation mark, or the only form of horizontal datum or vertical datum line.
The cylindrical section 11 of above-mentioned test pin 1 can be hollow cylinder, and its inner surface is interior hexagonal structure, in order to test pin
1 installation and removal.
Specifically, guide 2 can be provided with two, and have pre-determined distance between two guidees 2, to meet that having two groups treats
Application during 8 operating mode of nut is detected, while the relative positional accuracy between two nuts 8 to be detected can also be detected.It is apparent that guide
2 specific number can according to actual use situation determine, such as can also be one, three or more.
In detection process, the product 7 with nut 8 to be detected is fixed on cubing body 0, rotational installation plate 3 makes
It rotates around rotary shaft 9 relative to pedestal 5 to close to the direction of product 7, when turning to installing plate 3 and being fitted with the surface of product 7,
Then installing plate 3 rotate in place, now, the center of guide 2 and the theoretical welding position central coaxial of nut 8 to be detected；Then, will
The thread segment 12 of test pin 1 is screwed into nut 8 to be detected by way of screw thread cooperation, and pin 1 to be detected enters nut 8 to be detected
After appropriate depth, measuring the deviation between the center of test pin 1 and the center of guide 2 using slide measure or other detection instruments is
The position degree deviation of weld bolt can be learnt.So, weldering can be detected by the welded nut position degree error measuring means 100
Nut location precision after connecing, supported so as to provide data for nut location adjustment, ensure that the assembly precision of associated components.
Further, the external diameter of the cylindrical section 11 of above-mentioned test pin 1 is more than the correspondence of nut 8 to be detected on the product 7
The via aperture at place；So, when the thread segment 12 of test pin 1 screws in nut 8 to be detected, when test pin 1 reaches specified location,
The end face of cylindrical section 11 is overlapped on the surface of product 7, not only ensure that the stability of test pin 1, avoids it when measuring
Rock, and there is positioning action, avoid test pin 1 screw in nut 8 to be detected depth it is too deep or excessively shallow, it is accurate to improve measurement
True property and convenience.
In order to improve the connection reliability and convenience between pedestal 5 and installing plate 3, can be set between installing plate 3 and pedestal 5
Put connecting plate 4, one end of the connecting plate 4 is rotatablely installed in the pedestal 5 by the rotary shaft 9, its other end with it is described
Installing plate 3 is fixedly connected.
Further, welded nut position degree error measuring means 100 provided by the present invention also include fastening bolt 6,
In the detection state, the pedestal 5 is fixedly connected with the connecting plate 4 by the fastening bolt 6；So, installation is worked as
When plate 3 turns to predeterminated position relative to pedestal 5, the position of connecting plate 4 and pedestal 5 is limited by fastening bolt 6, so as to avoid
Installing plate 3 shakes, and further ensures accuracy of detection.
Specifically, said base 5 can be U-shaped structure, open up via, rotary shaft 9 respectively on the biside plate of U-shaped structure
It is installed in two vias, and can be rotated in via inner circumferential, a part for connecting plate 4 is arranged on the accommodation space of U-shaped structure
Interior, it is outer and be bolted with installing plate 3 or the mode such as clamping is fixedly connected that another part stretches out pedestal 5；In pedestal 5
Mounting hole is further opened with bottom plate, fastening bolt 6 is installed in the mounting hole, and mounting hole can be screwed hole, and fastening bolt 6 is revolved
Entering screwed hole can fix, and mounting hole can also be unthreaded hole, and fastening bolt 6, which passes through to fix by the nut of matching after unthreaded hole, is
Can, it is thus evident that connecting plate 4 should also offer the via that can pass through fastening bolt 6.
In theory, pedestal 5 is used to whole detection means 100 being arranged on cubing body 0, as long as can realize
Installation is reliable, and its concrete structure is not limited to U-shaped structure, or the form of platy structure or contiguous block.
Below by taking the welded nut at body hinge mounting hole as an example, detection means 100 provided by the present invention is sketched
The course of work.
As shown in Figure 4, Figure 5, car door assembly part is fixedly mounted on cubing body 0, rotates installing plate 3, rotate in place
It is fixed afterwards using fastening bolt 6, after installing plate 3 rotate in place, the center of guide 2 and the theoretical welding position of bolt to be detected
Put central coaxial；The thread segment 12 of test pin 1 is screwed into nut 8 to be detected by way of screw thread cooperation, due to test pin 1
The external diameter of cylindrical section 11 be more than via aperture at nut 8 to be detected on product 7, when screwing in place, the end face of cylindrical section 11
The surface of product 7 is resisted against, ensures that test pin 1 does not shake；Test pin 1 uses slide measure or other inspections after being screwed into
The deviation surveyed between the center of tool detection test pin 1 and the center of guide 2 can learn the position degree deviation of bolt to be detected, tool
Physical examination can be by detecting the deviation at the coordinate system scribe line position on guide 2 when surveying, and detection draws test pin 1 in a coordinate system
Deviation, it that is to say the deviation of nut 8 to be detected in a coordinate system.
Some one exemplary embodiments of the present invention are only described by way of explanation above, undoubtedly, for ability
The those of ordinary skill in domain, without departing from the spirit and scope of the present invention, can be with a variety of modes to institute
The embodiment of description is modified.Therefore, above-mentioned accompanying drawing and description are inherently illustrative, should not be construed as to the present invention
The limitation of claims.
