Abstract
The utility model discloses a punching jig for a three-connection square tube. The punching jig comprises a square casing. A first square through hole is arranged at the center position of an upper panel of the square casing, a left lateral plate and a right lateral plate perpendicular to the upper panel are extended from two sides of the upper panel, and a second square through hole is respectively arranged on the left lateral plate and the right lateral plate. By means of the mode, the punching jig for the three-connection square tube is simple in structure, convenient to operate, accurate in punching position and high in punching efficiency.
Description
Technical field
The utility model relates to machining tool field, particularly relates to a kind of three and connects the square tube punching jig.
Background technology
At present, for convenient transportation and saving space, the edge of some supports can be arranged to certain-length conveniently transports and stacks, when needing to use these supports, again these edges are assembled, during the edge assembling, general adopt two square tubes or three that connect to connect square tube and carry out connection between the edge, three to connect square tube be the square tube that square through hole is arranged on three faces, by square through hole edge is linked together, traditional three connect that the square tube punching is general adopts pure manually-operated pattern, be that operating personnel indicate the position that will punch and the size in hole by line on the square tube that will punch, then manually-operated is punched, owing to will make a call to three square through holes in square tube, some also will beat some circular holes as auxiliary installing hole, during the manually-operated punching, often there is certain error in the punch position of square hole and circular hole, so that three to connect the square tube scrappage higher, perforating efficiency is low.
The utility model content
The technical problem that the utility model mainly solves provide a kind of simple in structure, easy and simple to handle, perforating efficiency is high three connects the square tube punching jig.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of three to connect the square tube punching jig, comprising: square casing; Described square casing top panel center is provided with first square through hole; Described top panel both sides are extended with left and right two side plates perpendicular to described top panel; All be provided with second square through hole on described left and right two side plates.
In preferred embodiment of the utility model, also be provided with two circular holes on the described top panel; Described circular hole is distributed in described the first square through hole both sides, and symmetrical with respect to described top panel center line.
In preferred embodiment of the utility model, the described first square clear size of opening is more than or equal to the described second square clear size of opening.
In preferred embodiment of the utility model, described left and right two side plates are provided with chamfering.
The beneficial effects of the utility model are: described in the utility model a kind of three connect the square tube punching jig, and it is simple in structure, easy and simple to handle, improved perforating efficiency.
Description of drawings
Fig. 1 is the structural representation that the utility model three connects one preferred embodiment of square tube punching jig;
The mark of each parts is as follows in the accompanying drawing: 1, top panel, the 11, first square through hole, 12, circular hole, 2, left plate, 3, right plate, the 4, second square through hole.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
See also Fig. 1, a kind of three connect the square tube punching jig, comprise: square casing, square casing top panel 1 center is provided with first square through hole 11, also be provided with two circular holes 12 on the top panel 1, two circular holes 12 are distributed in the first square through hole 11 both sides, and symmetrical with respect to top panel 1 center line, top panel 1 both sides are extended with perpendicular to the left plate 2 of top panel 1 and right plate 3, two side plate bottoms are provided with chamfering, all be provided with the second square through hole 4, the first square through holes 11 sizes on left plate 2 and the right plate 3 greater than the second square through hole 4 sizes.
Described in the utility model a kind of three connect the square tube punching jig, when connecing square tube and punch to three, what only need to punch three connects square tube and is positioned in the square casing, be about to three connect square tube want perforated surfaces respectively with top panel 1, left plate 2 and right plate 3 fit, the chamfering that left plate 2 and right plate 3 bottoms are provided with convenient three connects picking and placeing of square tube, can connect square tube to three by the first square through hole 11 and the second square through hole 4 and play the square hole operation, some three connects square tube and also needs to make a call to two auxiliary circular ports, this moment is by two circular holes 12, can connect square tube three and offer circular port, easy and simple to handle, punch position is accurate, and perforating efficiency is higher.
Be different from prior art, described in the utility model a kind of three connect the square tube punching jig, and simple in structure, easy and simple to handle, punch position accurately, perforating efficiency is higher.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
