Technical Field

[0001] The utility model belongs to the field of industrial processing, and particularly relates to an auxiliary device for inspecting the perpendicularity of an insertion interface. Background Art

[0002] The car body frame of the track profile needs to insert and splice multiple profile sections and then weld them together. To ensure that the internal and external contours of the car body meet the design requirements after welding, requirements are imposed on the perpendicularity at the insertion interface. Due to the special structure of the profile insertion interface, a conventional angle gauge cannot accurately measure its perpendicularity, thus affecting the assembly accuracy of customers. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is: to overcome the deficiencies of existing measuring tools, and provide an auxiliary device for inspecting the perpendicularity of an insertion interface, which avoids the influence of inconvenient measurement on the accuracy of measurement data and can improve the inspection efficiency and accuracy.

[0006] Furthermore, the reference template is perpendicularly connected to the bottom plate, and the reference template and the bottom plate are of an integral structure.

[0007] Furthermore, the avoidance groove is an open oval groove. The opening size of the avoidance groove matches the vertical distance between the interference measurement areas on the profile to be detected, and the inner diameter size of the avoidance groove matches the outer diameter size of the interference measurement areas on the profile to be detected.

[0010] Furthermore, a storage hole is provided at one end of the reference template on the same side as the second working area. The storage hole is mainly used for hanging, collecting, and storing.

[0011] The lower end surface of the reference template is the template reference surface. When measuring the profile, this surface is used as the reference surface. The template reference surface is a horizontal plane.

[0012] The included angles between the template reference plane and the first working area and the second working area are both 90° ± 0.02°.

[0013] The beneficial effects of the present utility model are as follows:

[0026] The names of the messages or information exchanged between multiple devices in the embodiments of the present utility model are only for illustrative purposes and are not used to limit the scope of these messages or information. Embodiment 1

[0027] As Figures 1-3 shown, an auxiliary device for inspecting the perpendicularity of an insertion interface includes a reference template 1 and a bottom plate 2. The reference template 1 is vertically connected to the bottom plate 2, and the reference template 1 and the bottom plate 2 are an integral structure.

[0028] An open-ended elliptical groove 3 is provided on the right side edge of the bottom plate 2. The inner diameter dimension of the open-ended elliptical groove 3 matches the outer diameter dimension of the interference measurement area 11 on the work head 4 to be detected, and the opening dimension of the open-ended elliptical groove 3 matches the vertical distance between the interference measurement areas 11 on the work head 4 to be detected, so that when measuring, the interference measurement area 11 can enter the open-ended elliptical groove 3, facilitating the measurement of the points to be measured behind the interference measurement area 11.

[0029] Below the reference template 1, the area on the same side as the open-ended elliptical groove 3 on the bottom plate 2 is the first working area 6, and the area on the opposite side of the avoidance groove is the second working area 7.

[0030] The lower end face of the reference template 1 is a template reference surface 8. When measuring profiles, this surface is used as the reference surface. The template reference surface 8 is a horizontal plane.

[0031] The included angles between the template reference surface 8 and the first working area 6 and the second working area 7 are both 90°.

[0032] A storage hole 9 for convenient hanging and storage is provided at one end of the reference template 1 on the same side as the second working area 7.

[0033] When detecting the end perpendicularity of the tool head 4, place the tool head 4 to be detected in the first working area 6, put the interference measurement area 11 thereon into the open oval groove 3, make the upper end surface of the tool head 4 contact and connect with the template reference surface 8, and push the tool head 4 towards the open oval groove 3 until one of the two measurement points 5 on the upper and lower parts of the tool head 4 contacts the right side surface of the bottom plate 2. At this time, use a feeler gauge to measure the gap between the two measurement points 5 that is not close to the right side surface of the bottom plate 2. If the measurement result is within the error use range, the end perpendicularity of the tool head 4 is qualified; if the measurement result exceeds the error use range, the end perpendicularity of the tool head 4 is unqualified. Embodiment 2

[0034] As Figure 1 and Figure 4 shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, the end perpendicularity of the female head 10 is measured. Since there is no interference measurement area 11 on the female head 10, the female head 10 can be measured in the second working area 7. Make the upper end surface of the female head 10 contact and connect with the template reference surface 8, and push the female head 10 towards the bottom plate 2 until one of the two measurement points 5 on the upper and lower parts of the female head 10 contacts the left side surface of the bottom plate 2. At this time, use a feeler gauge to measure the gap between the two measurement points 5 that is not close to the left side surface of the bottom plate 2. If the measurement result is within the error use range, the end perpendicularity of the tool head 4 is qualified; if the measurement result exceeds the error use range, the end perpendicularity of the tool head 4 is unqualified.
