Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

In the embodiment of the spraying shielding jig, the shielding of the hole on the workpiece is realized by using the shielding jig.

Referring to fig. 3, the shielding jig is composed of three parts which can be separated from each other, and specifically includes a plug 10, a separation plate 20, and an extraction cover 30.

The plug 10 is in a cylindrical structure; the diameter of the plug 10 is matched with the size of the hole in the workpiece, so that the plug 10 can be smoothly plugged into the hole.

In the present embodiment, referring to fig. 4-5, a ring disc 13 is disposed on the plug 10, and the ring disc 13 divides the plug 10 into a plug-in portion 11 and a plug-in portion 12; here, the insertion portion 11 is used for insertion into a hole of a workpiece, and the ring plate 13 can be brought into abutting contact with an end face of the workpiece; through setting up ring dish 13 can realize effectual spacing when the work piece hole is filled in to portion 11 of filling in, avoid appearing whole end cap 10 and fill in the downthehole condition of work piece.

The separating plate 20 and the plug are arranged in a separable way; the separating plate 20 is provided with a plurality of through holes 21 distributed in an array; the diameter of the through hole 21 is matched with that of the inserting part 12, and the diameter of the through hole 21 is smaller than that of the ring disc 13; the through hole 21 is mainly used for the insertion part 12 to pass through, so that the separation plate 20 can be inserted and connected with the insertion part 12 through the through hole 21; so that the part of the inserting part 12 passing through the through hole 21 can be matched with the magnetic ring body 31 in the extracting cover 30 in a magnetic attraction way.

The extraction cover 30 is arranged with the separation plate 20 and the plug 10 in a separable way; the magnetic ring bodies 31 are distributed in an array on the extraction cover 30 at a side opposite to the separation plate 20, and the magnetic ring bodies 31 are arranged corresponding to the through holes 21 one by one.

The one-to-one arrangement here can be understood as that, when the extraction lid 30 is coupled and mated with the separation plate 20, the axes of the mutually corresponding magnetic ring bodies 31 are coaxial and collinear with the axis of the through hole 21; thus, the inserting part 12 passing through the through hole 21 can be matched with the magnetic ring body 31 in a magnetic attraction manner.

For the convenience of understanding, the following detailed description is provided for the specific use of the shielding jig:

the plugging part 11 of each plug 10 is plugged into the hole of the workpiece until the ring disc 13 is contacted with the end face of the workpiece, so that the depth consistency of the whole plug 10 is ensured; then carrying out metal spraying operation on the surface of the workpiece, wherein the metal spraying layer is uniformly distributed on the surface of the workpiece; after the spraying operation is finished, the through hole 21 on the separating plate 20 is aligned with the plug-in part 12 of each plug 10 by using the separating plate 20, so that the separating plate 20 is connected with each plug 10 in a plug-in manner; finally, the extraction cover 30 is used, the extraction cover 30 is placed on the separation plate 20, and the magnetic ring body 31 on the extraction cover 30 is ensured to be matched with the inserting part 12 in a magnetic attraction manner; therefore, the separation plate 20 and the plug 10 can be lifted up only by applying upward force to the extraction cover, and the separation of the plug 10 from the workpiece hole is realized.

It should be noted that, in order to ensure that the three separable components can be extracted simultaneously under the action of the magnetic attraction force, the magnetic attraction force generated directly by the magnetic ring 31 and the insertion part 12 should be at least greater than the gravity force of the separating plate 20 and all the plugs 10.

Taking out all the plugs 10 under the action of the extraction cover, and directly continuing to use the plugs on the next workpiece; at this time, after all the plugs 10 are inserted into the workpiece holes, an operator acts on the separating plate 20 with one hand to keep the separating plate 20 still, and extracts the extraction cover 30 upwards with the other hand, so that the magnetic ring body 31 on the extraction cover 30 is separated from the inserting part 12; then the separating plate 20 is taken down to make the plug 10 remain on the workpiece; and then, carrying out metal spraying on the workpiece, and after the spraying is finished, extracting the plug 10 by using the separation plate 20 and the extraction cover 30.

Through the spraying tool that has three separable part to constitute more than adopting, not only the operation of being convenient for can also the spraying area on the effectual assurance work piece, has very big promotion effect to guaranteeing work piece spraying quality and improving spraying efficiency.

In this embodiment, the plug-in portion 11 is made of rubber, and the plug-in portion 12 is made of metal; the plug-in part 11 made of rubber cannot damage workpieces, and the plug-in part 12 made of metal is convenient to realize magnetic attraction matching with the magnetic ring body 31.

Optionally, an annular wall 22 is disposed on an end surface of the separating plate 20 facing the extracting cover 30, the annular wall 22 and the separating plate 20 together form a cavity, and the cavity is matched with the extracting cover 30 in size.

By providing a cavity of annular configuration to facilitate a location-fit mounting between the extraction cap 30 and the separator plate 20.

In the present embodiment, the extraction cap 30 includes a cap body 32 and a protrusion 33 provided on the cap body 32; the magnetic ring body 31 is distributed in the protruding part 33 in an array; the protrusion 33 is sized to fit the cavity and the two may be mated by mating.

When the extraction cap 30 is used to fit the cavity, the protrusion 33 fits the size of the cavity; therefore, when the separation plate 20 and the extraction cap 30 are engaged, the protrusion 33 is directly inserted into the cavity, and the cavity and the protrusion 33 are engaged to position the separation plate 20 and the extraction cap.

By adopting the technical scheme, the problem that the traditional workpiece is not sprayed in place in a large area is solved by adopting a cylindrical plug mode; referring to fig. 6, the plug with a cylindrical structure is only used for shielding the hole on the workpiece, so that the part around the hole can be sprayed with metal, the uniformity of the conductivity of the workpiece is ensured, and the stability of the product is ensured.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
