Specifically, taking the coaxiality detection device for the hinge shaft 51 of the vehicle door 5 as an example, one of the two positioning blocks 2 can be matched with the upper hinge shaft and the other can be matched with the lower hinge shaft, when the central axes of the two positioning blocks 2 and the upper hinge shaft and the lower hinge shaft can be matched due to the collineation, the coaxiality of the upper hinge shaft and the lower hinge shaft is consistent, and when one of the positioning blocks 2 can be matched with the corresponding hinge shaft 51 and the other cannot be matched, the upper hinge shaft and the lower hinge shaft are different.
Further, since the two positioning blocks 2 are movable with respect to the guide bar 1, when the coaxiality of the hinge shafts 51 of the doors 5 for detecting different vehicle types is detected, the positioning blocks 2 can be moved to the fitting positions according to the positions of the upper and lower hinge shafts, thereby realizing the versatility of detection. The hinge shaft coaxiality detection device can be flexibly applied to different vehicle types, multiple sets of detection tools are not required to be developed, and cost is saved.
According to the hinge shaft coaxiality detection device provided by the embodiment of the utility model, the two positioning blocks 2 are movably sleeved on the guide rod 1, the positioning blocks 2 are provided with the positioning holes 24 matched with the hinge shafts 51, and the central axes of the two positioning holes 24 are collinear, so that the coaxiality of different hinge shafts 51 can be judged by utilizing the matched state of the two positioning blocks 2 and the corresponding hinge shafts 51, and as the two positioning blocks 2 are movable, the positioning blocks 2 can be moved to the matched positions according to the positions of the upper hinge shafts and the lower hinge shafts during coaxiality detection of the hinge shafts 51 of the vehicle doors 5 of different vehicle types, so that the detection universality is realized. The hinge shaft coaxiality detection device can be flexibly applied to different vehicle types, multiple sets of detection tools are not required to be developed, and cost is saved.
Further, as shown in fig. 1 to 3, the hinge shaft coaxiality detecting apparatus further includes a locking piece 3, the locking piece 3 being capable of locking the positioning block 2 so as to make the positioning block 2 immovable relative to the guide bar 1, and the locking piece 3 being capable of releasing the positioning block 2 so as to make the positioning block 2 movable relative to the guide bar 1.
Therefore, when the hinge shaft coaxiality detection device is applied, the locking piece 3 needs to be released according to the position of the hinge, the positioning block 2 is moved to the adapting position, and then after the positioning block 2 is assembled with the corresponding hinge shaft 51, the positioning block 2 is locked by the locking piece 3.
Specifically, the number of the locking pieces 3 may be two to control the locking and releasing of the two positioning blocks 2 respectively, in a specific operation, in order to facilitate a single person's operation, one positioning block 2 may be moved first, after the positioning block 2 is matched with the hinge shaft 51, the locking piece 3 opposite to the positioning block 2 is locked, then the other positioning block 2 is moved, the above operation process is repeated, and finally the coaxiality detection of different hinge shafts 51 is completed.
It should be noted that, the locking member 3 may take various forms, for example, as shown in fig. 1 to 3, the positioning block 2 has a mating hole 22 through which the guide rod 1 passes and a locking hole 31 communicating with the mating hole 22, and the locking member 3 is a pre-tightening bolt that passes through the locking hole 31 and can be screwed to lock or release the positioning block 2.

Alternatively, the locking piece 3 may also be a stop nut sleeved on the guide rod 1, and after the positioning block 2 moves in place, the stop nut may be used to prevent the positioning block 2 from sliding.
Preferably, the cross section of the guide bar 1 is a polygonal structure, and the mating hole 22 is a polygonal hole adapted to the cross section shape of the guide bar 1. Therefore, after the polygonal guide rod 1 is matched with the positioning block 2, the positioning block 2 can be prevented from rotating circumferentially by utilizing multi-face limiting, and the reliability of coaxiality detection is ensured.
Optionally, the limit matching of the guide rod 1 and the positioning block 2 is not limited to adopting the above structure, and the guide rod 1 can be utilized to set a limit bump extending along the length direction of the guide rod, and one side of the positioning hole 24 can be set with a limit groove matched with the limit bump, so that the effect of preventing the positioning block 2 from rotating circumferentially can be achieved by utilizing the matching of the limit bump and the limit groove.
Preferably, as shown in fig. 1-3, the central axis of the locking hole 31 is perpendicular to the central axis of the mating hole 22. Therefore, after the pre-tightening bolt is screwed, the locking reliability of the positioning block 2 is high, and the sliding is not easy to occur.
In some embodiments, as shown in fig. 1-3, the positioning block 2 includes a connecting end 21, a free end 23, and a transition 25 therebetween, the connecting end 21 being for connection with the guide rod 1, the free end 23 having a positioning hole 24. Specifically, as shown in fig. 1 to 3, the positioning block 2 has an elongated flat plate-like structure, and the connection end 21 and the free end 23 are both ends of the flat plate.
Preferably, as shown in fig. 1-3, the cross-sectional area of the transition 25 is smaller than the cross-sectional area of the free end 23, and the cross-sectional area of the transition 25 is smaller than the cross-sectional area of the connecting end 21. Therefore, the transition portion 25 with smaller cross-sectional area can reduce materials and save cost, and as the matching hole 22 and the positioning hole 24 are respectively arranged at the connecting end 21 and the free end 23, the relative shrinkage of the transition portion 25 can not affect the setting model of the matching hole 22 and the positioning hole 24, namely, the matching of the hinge shaft 51 and the positioning block 2.
Preferably, as shown in fig. 1-3, the outer peripheral surface of the free end 23 is arcuate. It should be noted that, the mating portion between the door 5 and the hinge shaft 51 is generally a sleeve structure, and the free end 23 with an arc outer peripheral surface can truly simulate the outline of the sleeve structure, so as to facilitate improvement of the detection accuracy.
Optionally, the outer peripheral surface of the connecting end 21 is also arc-shaped, the transition portion 25 comprises two opposite side surfaces in the width direction of the positioning block 2, the two side surfaces are recessed towards the direction close to each other to form an arc-shaped surface, and two ends of the two side surfaces are respectively and smoothly butted with the outer peripheral surfaces of the connecting end 21 and the free end 23, so that the forming and the manufacturing are convenient.
Preferably, as shown in fig. 1-3, a handle 4 is provided on the guide bar 1 to facilitate handling by a human hand.
Further, the two positioning blocks 2 are respectively positioned at two sides of the handle 4, so that the whole hinge shaft coaxiality detection device is good in balance, labor-saving in operation and convenient to use.
Further, the guide bar 1 is provided with a size scale, and the size scale is set with the middle position of the guide bar 1 as a starting point and gradually increases toward the two ends of the guide bar 1. Therefore, an operator can calculate the distance between the upper hinge shaft and the lower hinge shaft according to the scale values corresponding to the two positioning blocks 2, and the functional diversity of the hinge shaft coaxiality detection device is improved.
