An inspection apparatus for an optical fiber preform polishing rod according to the present invention will be described with reference to fig. 1 to 10.
As shown in fig. 1 to 2, the utility model provides a testing device of prefabricated grinding rod of optic fibre, include: the clamping device 1 and the tolerance detection device; the clamping device 1 comprises a first clamping plate 11 and a second clamping plate 12, and the first clamping plate 11 and the second clamping plate 12 are used for clamping the outer sides of any group of opposite side surfaces on the optical fiber prefabrication grinding rod 2; with one of the opposite side surfaces of the optical fiber preform polishing rod 2 fitted to the first clamping plate 11, a gap is formed between the other of the opposite side surfaces of the optical fiber preform polishing rod 2 and the second clamping plate 12; the tolerance detection device is used for carrying out tolerance detection on the clearance. The optical fiber preform polishing rod 2 is referred to as a polishing rod in the following embodiments.
Specifically, this embodiment can set up the centre gripping interval of two splint through placing the stick of polishing between first splint 11 and second splint 12 to form the clearance between the side of stick of polishing and one of them splint, be convenient for based on the tolerance detection to the clearance indirectly realize the tolerance detection to the machining size of the relative side on the stick of polishing. For the detection mode based on slide caliper, the utility model discloses not only easy operation is convenient, has increased substantially the detection efficiency to the stick of polishing, has ensured the accuracy that detects the machining precision of stick of polishing moreover.
It should be noted that the opposite side surfaces of the optical fiber preform polishing rod 2 shown in the present embodiment specifically refer to two side surfaces of the optical fiber preform polishing rod 2 which are arranged oppositely and in parallel, and since the optical fiber preform polishing rod 2 is a regular octagonal prism, the side surfaces of the optical fiber preform polishing rod 2 form four sets of opposite side surfaces. When the optical fiber preform polishing rod is inspected, the actual arrangement positions of the first clamping plate 11 and the second clamping plate 12 are not particularly limited, and the arrangement positions of the first clamping plate 11 and the second clamping plate 12 can be interchanged. In this embodiment, a side surface of the optical fiber preform polishing rod 2 may be attached to the first clamping plate 11, and a gap formed between the other corresponding side surface of the optical fiber preform polishing rod 2 and the second clamping plate 12 is subjected to tolerance detection. In this embodiment, one side surface of the optical fiber preform polishing rod 2 may be attached to the second clamping plate 12, and a tolerance of a gap formed between the other corresponding side surface of the optical fiber preform polishing rod 2 and the first clamping plate 11 may be detected.
Meanwhile, in order to facilitate accurate tolerance detection of the machining dimension of the opposite sides on the grinding rod, the present embodiment specifically sets the clamping interval between the first clamping plate 11 and the second clamping plate 12 to be equal to the sum of the standard width and the preset value between the opposite sides of the grinding rod. The embodiment can set the preset value according to actual requirements, and select the tolerance detection device with corresponding specification according to the set preset value.
In actual detection, if the width between the opposite side surfaces of the grinding rod is equal to the standard width, the width of the gap shown in the present embodiment should be equal to the preset value. However, since the grinding rod has a machining error, the actually detected width of the gap has a certain deviation from the preset value, and the deviation is correspondingly the deviation of the actual width between the opposite side surfaces of the grinding rod from the standard width, so that the embodiment can indirectly realize the tolerance detection of the machining dimension of the opposite side surfaces of the grinding rod according to the tolerance detection of the gap.

For example, in the case where the preset value is set to 5mm and the tolerance value is set to 0.05mm, the diameter of the through end 31 of the through-stop gauge 3 shown in the present embodiment is 4.95mm, and the diameter of the end-stop 32 is 5.05 mm.
As shown in fig. 6 to 9, when tolerance detection is performed on the gap, the through end 31 and the stop end 32 of the go-no-go gauge 3 only need to be inserted into the gap, respectively. Fig. 8 specifically illustrates that the through end 31 of the go-no-go gauge 3 is inserted between the grinding rod and the second clamping plate 12, and fig. 9 specifically illustrates that the stop end 32 of the go-no-go gauge 3 is inserted between the grinding rod and the second clamping plate 12.
When the tolerance of the gap is judged, if the through end 31 can pass through the gap and the stop end 32 cannot pass through the gap, the width between the opposite side surfaces of the optical fiber prefabrication grinding rod 2 is within the tolerance allowable range; if the through end 31 cannot pass through the gap, the width between the opposite sides of the optical fiber preform polishing rod 2 is greater than the tolerance allowable width; if the end stop 32 is capable of passing through the gap, the width between the opposite sides of the optical fiber preform polishing rod 2 is smaller than the tolerance allowable width.
Wherein, in the case of setting the tolerance range to ± 0.05mm, the tolerance shown in the present embodiment allows the width to be larger than the difference between the standard width between the opposite side surfaces of the grinding bar and 0.05mm, and smaller than the sum of the standard width between the opposite side surfaces of the grinding bar and 0.05 mm.
