Description
Technical Field
The utility model belongs to the technical field of the panel silk screen printing, especially, relate to a work piece positioner suitable for silk screen printing concentric circles.
Background
In the existing sheet metal production, a very silk-screen printing part is provided, and concentric circles need to be silk-screen printed outside a round hole of the part during processing. During silk-screen printing, the outer edge of the workpiece is used as the positioning reference between the silk-screen printing plate and the silk-screen workpiece. However, when the sheet metal part is bent or welded, the appearance has the condition of deviation of a small amount of sizes, and when the silk-screen concentric circles use the appearance of the first part as the common positioning reference of the batch silk-screen parts, the circles processed by silk-screen of other parts and the round holes of the parts are not concentric due to the processing deviation of the appearance sizes of other parts and the first part. Therefore, the external dimension of the part is used as the screen printing positioning reference, and the screen printing plate is correspondingly adjusted and positioned for each part, so that the screen printing processed circle is concentric with the circular hole of the part. Therefore, each piece of the screen printing mould is low in independent positioning efficiency and large in labor amount, and a screen printing mould capable of repeatedly screen printing large-batch concentric circular parts is needed.
Disclosure of Invention
The utility model aims to solve the technical problem that the problem to the aforesaid exists provides a work piece positioner suitable for silk screen printing concentric circles.
The utility model provides a technical scheme that above-mentioned technical problem adopted is: the workpiece positioning device is characterized by comprising a supporting plate and a positioning shaft, wherein a mounting hole is formed in the supporting plate, the mounting hole and the screen printing workpiece hole are concentrically arranged, and the positioning shaft is connected with the mounting hole through a connecting piece.
According to the scheme, the boss is arranged at the top of the positioning shaft and is of a T-shaped structure, the diameter of the top of the boss is smaller than the diameter of the hole of the silk-screen printing workpiece, and the diameter of the bottom of the boss is larger than the diameter of the hole of the silk-screen printing workpiece.
According to the scheme, the height of the boss is smaller than the thickness of the silk-screen workpiece.
According to the scheme, the mounting hole is a counter bore, and the connecting piece is a countersunk head screw.
According to the scheme, the center of the bottom of the positioning shaft is provided with a threaded hole, and the aperture of the threaded hole is the same as that of the mounting hole.
According to the scheme, one or two positioning shafts are arranged.
According to the scheme, the supporting plate is made of a galvanized steel plate, and the positioning shaft is made of polyformaldehyde resin.
The utility model has the advantages that: the workpiece positioning device suitable for screen printing concentric circles is provided, a large number of concentric circle workpieces can be repeatedly subjected to screen printing only by positioning once, the problem that each screen printing part needs to be subjected to screen printing positioning independently is effectively solved, the use is simple and convenient, and the production efficiency can be greatly improved.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Fig. 2 is a schematic structural diagram of a positioning shaft according to an embodiment of the present invention.
Fig. 3 is a silk-screen workpiece assembly diagram according to an embodiment of the present invention.
Detailed Description
For a better understanding of the present invention, the following description is given in conjunction with the accompanying drawings and examples.
As shown in fig. 1 and 2, the workpiece positioning device suitable for screen printing concentric circles comprises a supporting plate 1 and a positioning shaft 2, wherein a mounting hole 3 is formed in the supporting plate, the mounting hole and a screen printing workpiece hole 4 are concentrically arranged, and the positioning shaft is connected with the mounting hole through a connecting piece 5.
The top of the positioning shaft is provided with a boss 6 which is of a T-shaped structure, the diameter of the top of the boss is smaller than the aperture of a silk-screen printing workpiece hole, the diameter of the bottom of the boss is larger than the aperture of the silk-screen printing workpiece hole, and the height of the boss is smaller than the thickness of a silk-screen printing workpiece 7. When the silk-screen printing workpiece is installed, the top of the boss is inserted into the silk-screen printing workpiece hole and does not protrude out of the surface of the silk-screen printing workpiece.
The mounting hole is a counter bore, and the connecting piece is a countersunk screw.
The center of the bottom of the positioning shaft is provided with a threaded hole 8, and the hole diameters of the threaded hole and the mounting hole are the same. The threaded hole and the mounting hole can be two, so that the connection is more stable.
The positioning shafts are one or two, the single silk-screen hole part can be positioned only by one positioning shaft, and the multi-silk-screen hole part can be positioned only by two positioning shafts. The diameter of the positioning shaft can be selected, and is larger than the diameter of the bottom of the boss. The total height of the positioning shaft is slightly more than the height of the silk-screen workpiece by several millimeters, and if the silk-screen workpiece is a flat plate, the height of the positioning shaft can be selected optionally.
The supporting plate is processed by galvanized steel sheets; the positioning shaft is made of POM material.
As shown in fig. 3, in use: and aligning the round hole on the silk-screen workpiece to the positioning shaft, naturally sleeving the round hole, adjusting the silk-screen plate to enable the silk-screen concentric circle to be concentric with the round hole of the workpiece, fixing the position of the silk-screen table and the position of the supporting plate, namely completing positioning, and repeatedly performing silk-screen printing on other parts.
The present invention is only a preferred embodiment, and those skilled in the art can make various modifications, equivalent changes and modifications within the scope of the present invention by using the above disclosure.
