[0020] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0021] like Figures 1 to 4As shown, an air compressor housing weld inspection device comprises an inspection platform 1 and a special-shaped housing stabilizing structure 2, wherein the special-shaped housing stabilizing structure 2 is arranged on the surface of the inspection platform 1;

[0022] The detection platform 1 includes a base platform 11, a sub-platform 12 and an ultrasonic detector 13. The sub-platform 12 is fixedly connected to one side of the base platform 11, and the ultrasonic detector 13 is placed on the top of the sub-platform 12. After the special-shaped shell is stabilized on the base platform 11, the output end of the ultrasonic detector 13 can be used to detect the special-shaped shell;

[0023] The stabilizing structure 2 of the special-shaped shell includes a plurality of electromagnetic slideways 21 opened on the top of the base 11. The number of the electromagnetic slideways 21 is several and they are evenly distributed in a cross shape. The electromagnetic slideways 21 can be used as guide rails, so that the stabilizing member can slide along the electromagnetic slideways 21. The electromagnetic slideway 21 is internally clamped and slidably connected with an electromagnetic slider 22. The electromagnetic slider 22 can be used as a driving bearing individual to drive the stabilizing member to slide. The electromagnetic slideway 21 is a device that uses electromagnetic force to move. A linear motor is embedded in the electromagnetic slideway 21. The electromagnetic slider 22 generates movement through an electromagnet and a guide rail. A stabilizing sleeve 23 is fixedly connected to the top of the electromagnetic slider 22. The top of the stabilizing sleeve 23 is open. The stabilizing sleeve 23 is the main contact component with the special-shaped shell. Driven by other components, it can fit on the surface of the special-shaped shell to achieve a certain positioning and stabilizing effect. The stabilizing sleeve 2 3 is provided with a pull rod 24, the bottom of the pull rod 24 passes through the electromagnetic slider 22 and fits with the electromagnetic slide 21, the pull rod 24 and the electromagnet inside the electromagnetic slider 22 are staggered, the pull rod 24 and the electromagnetic slider 22 are slidably connected, the pull rod 24 is a transmission component, and the contact between the pull rod 24 and the electromagnetic slide 21 can also achieve a good positioning effect, avoiding the electromagnetic slider 22 from sliding easily when people do not need it, the top of the pull rod 24 is fixedly connected with a top plate 25, the surface of the top plate 25 is provided with an operating structure 26, the top plate 25 and the operating structure 26 are operating components, which can be used to cancel the positioning effect, the surface of the pull rod 24 is provided with a reset spring 27, the reset spring 27 is fixedly connected to the stabilizing sleeve 23 and the top plate 25, and the reset spring 27 as a reset component can ensure the fit between the pull rod 24 and the electromagnetic slide 21.

[0024] like Figure 3 As shown, a non-slip rubber block 3 is fixedly connected to the bottom of the pull rod 24 , and the non-slip rubber block 3 is slidably connected to the electromagnetic slider 22 . The non-slip rubber block 3 is interference-fitted with the electromagnetic slideway 21 under the drive of the reset spring 27 .

[0025] like Figure 3As shown, the operating structure 26 includes an operating groove 261 opened on the top of the top plate 25, and a pull rod 262 is fixedly connected inside the operating groove 261, which can increase the force application point on the top of the top plate 25, thereby making it convenient for people to pull the top plate 25, and then conveniently stop the limiting of the special-shaped shell stabilizing structure 2.

[0026] like Figure 3 As shown, the surface of the stabilizing sleeve 23 is provided with a buffer layer 4, and the buffer layer 4 is made of soft rubber. The buffer layer 4 is fixedly connected to the surface of the stabilizing sleeve 23. When the stabilizing sleeve 23 contacts the surface of the special-shaped shell, a certain impact effect will be generated between the stabilizing sleeve 23 and the special-shaped shell, and the buffer layer 4 can reduce and eliminate this impact, thereby avoiding damage to the special-shaped shell due to the impact.

[0027] like Figure 3 As shown, both sides of the electromagnetic slider 22 are fixedly connected with a snap-in strip 5, and both sides of the inner wall of the electromagnetic slide 21 are provided with a snap-in path 6. The snap-in strip 5 is snapped into the inside of the snap-in path 6, which can increase the snap-in effect between the electromagnetic slide 21 and the electromagnetic slider 22, avoid the electromagnetic slider 22 from being distorted or detached inside the electromagnetic slide 21, and ensure the stability of the sliding process.

[0028] like Figure 3 As shown, the surfaces of the electromagnetic slider 22 and the card strip 5 are fixedly connected with a smooth coating 7, the smooth coating 7 is in contact with the card track 6 and the electromagnetic slide 21 and is slidably connected, and the surface of the anti-slip rubber block 3 is not sprayed with the smooth coating 7. The smooth coating 7 can be used to reduce the friction between the electromagnetic slide 21 and the card track 6 and the electromagnetic slider 22 and the card strip 5, so as to avoid the phenomenon of sliding difficulty caused by excessive friction.

[0029] The working principle of the utility model is as follows: when in use, the air compressor special-shaped shell is first placed on the top of the base 11, and then the top plate 25 is pulled up through the operating structure 26, thereby driving the pull-out rod 24 to disengage from the inner wall of the electromagnetic slide 21, and then stop positioning, and then electromagnetic drive is used to make the stabilizing sleeve 23 slide along the electromagnetic slide 21 through the electromagnetic slider 22, so as to contact the surface of the special-shaped shell of the air compressor. After the contact is in place, the operating structure 26 can be released, and then the reset spring 27 is used to drive the pull-out rod 24 to contact the electromagnetic slide 21 to restore the positioning effect, and then the multi-directional and positioned stabilizing sleeve 23 can be used to limit and stabilize the special-shaped shell of the air compressor to avoid the phenomenon that the special-shaped shell of the air compressor is easily shaken and distorted during measurement. Compared with the existing detection workbench, the device has the ability to stably place the arc-shaped or special-shaped air compressor shell to avoid the arc-shaped or special-shaped air compressor shell from shaking and affecting the normal detection work of the ultrasonic flaw detector, and at the same time, no manual support is required from the detection personnel.

[0030] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
