Description

Technical Field

[0001] This utility model relates to an auxiliary tooling for ultrasonic wall thickness detection of methane pump housing, belonging to the field of auxiliary tooling technology for housing detection. Background Technology

[0002] When the wall thickness of the methane pump housing is detected ultrasonically, since the methane pump housing is arc-shaped, and the detection surface of the ultrasonic probe 10 is a plane, as shown below... Figure 2 As shown, the ultrasonic probe cannot be placed close to the arc-shaped methane pump housing for testing. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an auxiliary tooling for ultrasonic wall thickness detection of methane pump housing.

[0004] This utility model is achieved through the following technical solution.

[0005] This utility model provides an auxiliary tooling for ultrasonic wall thickness detection of a methane pump housing, comprising:

[0006] An auxiliary tooling for ultrasonic testing of the wall thickness of a methane pump housing, which allows the ultrasonic probe to be in close contact with the housing.

[0007] The testing auxiliary fixture includes a fixture testing panel, a bonding column, and a locking pin.

[0008] The tooling inspection panel is provided with a sliding hole for the bonding column to be slidably inserted, and a locking hole for the installation of a locking pin is provided on the tooling inspection panel. A locking pin for locking the position of the bonding column is fitted in the locking hole.

[0009] The tooling inspection panel has multiple sliding holes, and the number of locking holes and bonding posts is also multiple and corresponds to the number of sliding holes.

[0010] The tooling inspection panel has a probe inspection area in the middle for the ultrasonic probe to be closely attached to, and the probe inspection area is planar.

[0011] The beneficial effects of this utility model are as follows: after multiple bonding columns are slid and adjusted into place on the tooling inspection panel, they are closely attached to the outside of the arc-shaped methane pump housing. The ultrasonic probe is closely attached to the probe inspection area to realize ultrasonic detection of the wall thickness of the methane pump housing, which solves the problem that the existing ultrasonic probe cannot be closely attached to the arc-shaped methane pump housing for inspection.

[0015] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0016] like Figure 1 As shown.

[0017] This application discloses an auxiliary tooling for ultrasonic wall thickness detection of a methane pump housing, comprising:

[0018] The tooling inspection panel 1 is provided with a sliding hole for the sliding insertion of the bonding column 2. The tooling inspection panel 1 is provided with a locking hole 31 for the installation of the locking pin 3. The locking pin 3 is fitted in the locking hole 31 by interference fit or threaded pair. The locking pin 3 is installed in the locking hole 31 to lock the position of the bonding column 2.

[0019] The tooling inspection panel 1 has multiple sliding holes, and the number of locking holes 31 and bonding posts 2 is also multiple and corresponds to the number of sliding holes. This allows the multiple bonding posts 2 to be tightly attached to the outside of the arc-shaped methane pump housing 4.

[0020] The tooling inspection panel 1 has a planar probe inspection area 11 in the middle, and the inspection surface of the ultrasonic probe 10 is in close contact with the probe inspection area 11.

[0021] The planar detection surface of the ultrasonic probe 10 is in close contact with the probe detection area 11. The ultrasonic waves are transmitted through the tooling detection panel 1 and then through multiple bonding pillars 2 to the methane pump housing 4, realizing ultrasonic detection of the wall thickness of the outer area of ​​the arc-shaped methane pump housing 4. The wall thickness data of the methane pump housing 4 can be obtained by subtracting the dimensions of the tooling detection panel 1 and the bonding pillars 2 from the obtained data. Since the multiple bonding pillars 2 can slide and be adjusted into position on the tooling detection panel 1 to be in close contact with the outer side of the arc-shaped methane pump housing 4, the ultrasonic probe 10 is in close contact with the probe detection area 11 to realize ultrasonic detection of the wall thickness of the methane pump housing 4, which solves the problem that existing ultrasonic probes cannot be in close contact with the arc-shaped methane pump housing for detection.
