Abstract
Description
Technical Field
[0001] This utility model belongs to the field of coplanar detection tooling technology, and relates to an auxiliary device for indirectly detecting multiple coplanar blocks. Background Technology
[0002] like Figure 1 The diagram shows a special steel welded structural component. The spring box block 1 is embedded in a groove on the base ring 2 and welded together. The drawing requires that all eight spring box blocks 1 be coplanar after welding, so coplanarity testing of the eight spring box blocks 1 is necessary. After assembly, the structural component has many internal parts, leaving little space for inspection. The eight spring box blocks 1 are distributed on the left and right sides of the base plate 3 with large spacing, making it impossible to directly inspect the coplanarity of the spring box blocks 1 using general measuring tools. Utility Model Content

[0007] Among them, thread sealant is applied between the lower end of the special pin 4 and the first hole of the structural sample block 5.

[0026] To make the objectives, contents, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.
[0027] Reference Figures 2 to 8 As shown, the auxiliary device for indirectly detecting multiple coplanar blocks in this embodiment includes a special pin 4, a structural sample block 5, and a bolt 6. The structural sample block 5 has two holes. The lower end of the special pin 4 is fitted into the first hole of the structural sample block 5 and thread sealant is applied to ensure that the special pin 4 does not fall off. The bottom end face of the special pin 4 is flush with the bottom face of the structural sample block 5. The upper end of the special pin 4 passes through one hole of the spring box block 1 to be tested. The bolt 6 passes through the second hole of the structural sample block 5 and the other hole of the spring box block 1 and fixes the structural sample block 5 and the spring box block 1. A baseline is set on the upper part of the special pin 4 to mark the height of the spring box block 1.
[0028] The auxiliary device also includes a nut 7. When not measuring, the lower end of the bolt 6 passes through the second hole of the structural sample block 5 and is fixed with the nut 7 to prevent loss. When measuring multiple coplanar blocks, the nut 7 is removed.
[0029] The length of the special pin 4 is greater than the sum of the heights of the structural sample block 5 and the spring box block 1.
[0030] The upper circumference of the special pin 4 is engraved with a baseline. After the special pin 4 is installed into the structural sample block 5 and the spring box block 1, the baseline is 2mm to 5mm higher than the upper surface of the spring box block 1.
[0031] The position of the baseline on the special pin 4 is adjusted in real time according to the height of the measured spring box block 1.
[0032] The auxiliary device also includes a measuring ruler, which is a knife ruler or a steel ruler, used to measure the height difference between the baseline of the special pin 4 and the reference plane of the bottom ring 2.
[0033] The flatness of the upper surface of the base plate 3 cannot be guaranteed, but the flatness of the upper surface of the base ring 2 meets the requirements. Therefore, the upper surface of the base ring 2 can be used as a reference plane to calibrate the height of the upper surface of the spring box block 1.
[0034] By measuring each of the eight bomb boxes in turn, the coplanarity of the upper surfaces of the eight bomb boxes can be obtained.
[0035] After the measurement is completed, the structural sample assembly is removed, and the lower end of the bolt 6 is fixed with nut 7 to prevent loss.
[0036] In this embodiment, the special pin 4 is a straight-handled cylindrical shape. The shape of the structural sample 5 is selected according to actual needs, and can be circular, square, or irregular; the material of the structural sample 5 can be arbitrarily selected.
[0037] The operating principle of the auxiliary device for indirectly detecting multiple coplanar blocks in this embodiment is as follows: (Refer to...) Figure 6As shown, first, assemble the lower end of the special pin 4 into the first hole of the structural sample block 5, and apply thread sealant to ensure that the special pin 4 does not fall off, and that the lower end face is flush with the bottom surface of the structural sample block 5. During measurement, insert the upper end of the special pin 4 into one hole of the spring box block 1, and simultaneously use bolts 6 to tightly fix the structural sample block 5 and the spring box block 1 through the other hole. Use a general measuring tool such as a ruler and a straightedge to measure the height difference between the reference line of the special pin 4 and the reference plane of the bottom ring 2. Measure the remaining 7 spring box blocks in the same way, thus obtaining the coplanarity of the upper surfaces of the 8 spring box blocks. After the measurement is completed, remove the structural sample block assembly and fix the bolts 6 with nuts 7 to prevent loss.
[0038] As can be seen from the above technical solution, this utility model has the following significant features:
[0039] (1) The auxiliary device is designed to be flexible, and the structural sample can be different depending on the shape of the measured structural component.
[0040] (2) The position of the dedicated pin reference line of the auxiliary device can be changed in real time according to the thickness of the measured structural component, which is highly adaptable.
[0041] (3) The auxiliary device can achieve indirect, effective and rapid detection to obtain the coplanar situation, which solves the problem that it is impossible to detect coplanarity with general measuring tools in a limited space. Through data comparison, it can accurately repair, reduce manufacturing costs and improve production efficiency while ensuring product quality, and meet the product usage requirements.
[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
