[0025] Please refer to Figures 1-4 ,

[0026] Embodiment one: a flange hole detection device of a flange, comprising a bottom support plate 1, a top support plate 2 is arranged above the bottom support plate 1, the bottom support plate 1 and the top support plate 2 are connected through four fixed connecting columns 3 arranged uniformly, a valve 4 is arranged at the upper part of the bottom support plate 1, an upper flange 5 is arranged at the top end of the valve 4, a lower flange 6 is arranged at the bottom end of the valve 4, a top flange detection assembly 7 is arranged on the top support plate 2, and a bottom flange detection assembly 8 is arranged on the bottom support plate 1.

[0027] The top flange detection assembly 7 comprises a telescopic cylinder 701 arranged at the top end of the top support plate 2, the bottom of the top support plate 2 is provided with a lifting plate 702, the side edges of the lifting plate 702 are penetrated by the fixed connecting columns 3, the output end of the bottom of the telescopic cylinder 701 is connected with a driving connecting rod 703, the bottom end of the driving connecting rod 703 penetrates the top support plate 2 and is connected with the middle part of the top end of the lifting plate 702, and four upper detection rods 704 are uniformly arranged at the bottom end of the lifting plate 702.

[0028] The bottom flange detection assembly 8 comprises a support base 801 arranged at the bottom of the bottom support plate 1, four support connecting rods 802 are uniformly arranged around the top end of the support base 801, the top ends of the support connecting rods 802 are connected with the bottom end of the bottom support plate 1, a driving motor 803 is installed at the top end of the support base 801, the output end of the driving motor 803 is connected with a driving screw rod 804, the top end of the driving screw rod 804 rotates and penetrates the middle part of the bottom support plate 1, a driving screw sleeve 805 is threadedly sleeved on the driving screw rod 804, a driving connecting plate 806 is arranged at the top of the driving screw rod 804, four push-out connecting rods 807 are uniformly arranged around the outside of the driving screw sleeve 805, the top ends of the push-out connecting rods 807 penetrate the bottom support plate 1 and are connected with the bottom end of the driving connecting plate 806, an upper detection plate 808 is arranged at the top end of the driving connecting plate 806, and four lower detection rods 809 are arranged at the top end of the upper detection plate 808.

[0029] Embodiment two: the difference between the embodiment and the embodiment one is that the upper detection rods 704 are arranged corresponding to the flange holes on the upper flange 5.

[0030] So that the upper detection rods 704 can be inserted into the flange holes on the upper flange 5 more accurately under the pushing of the telescopic cylinder 701, and the flange holes are detected.

[0031] Embodiment three: the difference between the embodiment and the embodiment one is that a connecting plate is arranged at the top end of the driving screw rod 804.

[0032] So that the top end of the driving screw rod 804 does not abut against the driving connecting plate 806.

[0033] The difference between this embodiment and embodiment one is that the lower detection rod 809 is arranged corresponding to the flange hole on the lower flange 6.

[0034] When the lower detection rod 809 is driven to rotate by the driving motor 803, the driving screw sleeve 805 connected to the driving screw rod 804 can push the driving connection plate 806 upwards, and then push the lower detection rod 809 arranged on the upper detection plate 808 to determine whether it can be completely inserted into the flange hole on the lower flange 6, and then detect the flange hole.

[0035] In this embodiment, if the flange hole on the flange arranged on both sides of the existing valve is too large or too small, the user cannot observe or miss it, which will cause the valve to be unable to connect with the user's pipeline, thereby causing a major quality problem.

[0036] In summary, when the user needs to detect the size and position of the flange hole arranged on the upper flange 5 and the lower flange 6 of the valve 4, the user first needs to insert the flange hole on the lower flange 6 at the bottom of the valve 4 into the lower detection rod 809 in the lower flange detection assembly 8. Since the lower detection rod 809 is arranged according to the standard flange hole position and size, when the user can accurately insert the flange hole on the lower flange 6 into the lower detection rod 809, it means that the lower flange 6 meets the user's standard.

[0037] Then, the user starts the telescopic pneumatic cylinder 701 in the top flange detection assembly 7, so that the telescopic pneumatic cylinder 701 can push the lifting plate 702 through the driving connection rod 703, so that the upper detection rod 704 arranged at the bottom end of the lifting plate 702 can move towards the flange hole position on the upper flange 5. When the height of the upper flange 5 is insufficient, the user can also start the driving motor 803, so that the driving motor 803 can drive the driving screw rod 804, and then drive the driving screw sleeve 805 sleeved on the driving screw rod 804 to move upwards.

[0038] Since the side of the driving screw sleeve 805 is connected to the bottom end of the driving connection plate 806 through the push-out connecting rod 807, the driving screw sleeve 805 can be limited, avoiding the driving screw sleeve 805 rotating with the driving screw rod 804. The driving screw sleeve 805 pushes the driving connection plate 806 upwards through the push-out connecting rod 807, and then pushes the valve 4 inserted on the lower detection rod 809 upwards, so that the flange hole on the upper flange 5 can move to the upper detection rod 704.

[0039] When the upper detection rod 704 can be fully inserted into the flange hole on the upper flange 5, it indicates that the diameter of the flange hole on the upper flange 5 is qualified at this time, if it cannot be inserted, it indicates that the flange hole on the upper flange 5 is deviated or smaller, and whether the upper flange 5 and the lower flange 6 are aligned can also be detected, the device has simple structure and is convenient to use, can effectively detect whether the valve flange is qualified, ensures that the connection between the subsequent flange and the pipeline is more stable, so as to avoid major quality problems.
