Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example (b): a device for checking stud gasket assembly is disclosed, as shown in fig. 1 to 2, and comprises two guide blocks 3 for a gasket 53 to slide, wherein a slideway 33 for a stud 52 to slide and feed is arranged between the two guide blocks 3; an error-proof limiting block 4 protruding towards one side of the slideway 33 is arranged beside any one of the guide blocks 3, the error-proof limiting block 4 is arranged along the guiding direction of the slideway 33, and a first space 7 is reserved between the error-proof limiting block 4 and the guide block 3; and a mistake-proof material leakage notch 6 for the bolt 5 to pass through is formed in any guide block 3, and the mistake-proof material leakage notch 6 is positioned below the mistake-proof limiting block 4. Mistake proofing hourglass material breach 6 is along vertical direction being rectangular-shaped's of cross-section run through the breach structure, and mistake proofing hourglass material breach 6 width need be greater than the maximum diameter of nut 51 to make the bolt 5 that lacks gasket 53 can pass mistake proofing hourglass material breach 6.

A first interval 7 is reserved between the side face, close to the opening of the slide way 33, of the mistake proofing limit block 4 and the side face, close to the mistake proofing limit block 4, of the slide way 33 along the vertical direction. The first distance 7 is larger than the height of the nut 51 and smaller than the sum of the height of the nut 51 and the thickness of the spacer 53, the height of the nut 51 is in the axial direction of the bolt 5, and the thickness direction of the spacer 53 is in the axial direction of the bolt 5 after the spacer 53 penetrates through the bolt 5.

Since the bolt 5 is formed by integrally molding the nut 51 and the stud 52, when the bolt 5 is fed, the stud 52 penetrates into the slideway 33 between the first and

second slot plates

31 and 32 and slides along the axial direction of the slideway 33, and the nut 51 slides along the axial direction of the slideway 33 and slides on the side wall of the interference part 41.

Mistake proofing stopper 4 includes conflict portion 41 and the installation department 42 that is used for installing fixed that slides the contact with nut 51 lateral wall, and conflict portion 41 sets up on installation department 42 and sets up in the top of mistake proofing hourglass material breach 6, and installation department 42 sets up in the lateral wall of slide 33.

Mistake proofing stopper 4 still includes locking piece 10 that can supply conflict portion 41 altitude mixture control, and installation department 42 sets up the altitude mixture control groove 9 that can supply locking piece 10 to pass along being on a parallel with the axial direction of mistake proofing hourglass material breach 6, and locking piece 10 passes altitude mixture control groove 9 back screw thread and penetrates conflict portion 41. The mounting portion 42 is secured to the slideway 33 by a fastener 8. The height adjustment grooves 9 are two in number and symmetrically arranged on the mounting portion 42. Therefore, the nut 51 can be conveniently adjusted in time according to different height specifications during use.

The axial direction of the material mistake-proof gap 6 is perpendicular to the opening direction of the slideway 33. The two guide blocks 3 are sequentially divided into a first groove plate 31 and a second groove plate 32, a slideway 33 is formed between the first groove plate 31 and the second groove plate 32, and the mistaken-leakage-preventing notch 6 is arranged on the second groove plate 32.

The side of the first slot plate 31 departing from the slideway 33 is provided with a first extension rod 1, the side of the second slot plate 32 departing from the slideway 33 is provided with a second extension rod 2, the first extension rod 1 and the second extension rod 2 are connected through a connecting rod 13, and the connecting rod 13 simultaneously penetrates through the first extension rod 1 and the second extension rod 2; the outer wall threaded connection of connecting rod 13 has first stopper 11 that can contradict on first extension rod 1 lateral wall to and threaded connection has second stopper 12 that can contradict on second extension rod 2 lateral wall. In this embodiment, the number of the first limiting blocks 11 and the second limiting blocks 12 on the single connecting rod 13 is at least two, the two first limiting blocks 11 respectively abut against the two sides of the first extending rod 1, and the two second limiting blocks 12 respectively abut against the two sides of the second extending rod 2. The number of the connecting rods 13 is two, and is arranged along the axial direction of the first extension rod 1. In this embodiment, the first stopper 11 and the second stopper 12 are both nuts.

The positions of the first limiting block 11 and the second limiting block 12 on the connecting rod 13 are adjusted to adjust the width of the slideway 33 between the first slot plate 31 and the second slot plate 32, so that the opening width of the slideway 33 is adjusted, and the bolt 5 with different specifications can be conveniently adjusted in time and rapidly.

The working process is as follows:

first, the bolt 5 slides in the axial direction of the slide 33; when the bolt 5 is provided with the gasket 53, the thickness of the gasket 53 enables the nut 51 of the bolt 5 to slide on the surface of the abutting part 41, so that the bolt 5 smoothly slides over the side surface of the abutting part 41 without falling into the material mistake and leakage preventing gap 6; when the spacer 53 is not installed on the bolt 5, the nut 51 of the bolt 5 cannot slide on the surface of the abutting portion 41 due to the lack of the thickness of the spacer 53, so that the bolt 5 directly falls into the material missing preventing gap 6 when passing through the material missing preventing gap, thereby completing the error preventing process of the spacer 53 on the bolt 5.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
