Description
Technical field
The utility model relates to and a kind ofly is used to communicate by letter and the general instrument rack in industrial automation control field.
Background technology
In communication and industrial automation control field, need communication equipment or automatic control equipment be installed with general instrument rack usually, the structure of this class general instrument rack is based on sheet metal component substantially, constitutes by modes such as welding assembly or screw bindings again.In the general instrument rack based on sheet metal component, the interface that links mutually between parts adopts the mode of welding to form usually, because the positioning accuracy during welding is lower, and there is certain internal stress after the welding, for critical components such as the top frame that constitutes general instrument rack, underframe, columns, its dimensional accuracy and form and position tolerance will be difficult to guarantee.Particularly for will realizing pinpoint location structure, welding assembly repeatedly will more be difficult to guarantee the size and the form and position tolerance of location structure.In addition, generally all need to carry out manual grinding after the welding, operation inconvenience and be difficult to realize meticulous surface structure moulding is unfavorable for mass production.
The utility model content
At the above-mentioned defective of prior art, the technical problems to be solved in the utility model is: the general instrument rack of a kind of simple for structure, simple installation, accurate positioning is provided, reducing the manufacturing process difficulty, and finally reduces the cost of general instrument rack widely.
The utility model solves its technical problem by following scheme: construct a kind of general instrument rack, its main member comprises top frame, underframe and four root posts; The upper end of each root post links to each other with one of them bight of top frame, and the lower end links to each other with the corresponding bight of described underframe, forms the main body frame of rack; Wherein, the upper/lower terminal at the described column of each root is equipped with upper and lower column stiffener respectively; Described upper and lower column stiffener is connected with underframe with described top frame by bolt respectively, thereby realizes being connected between described column and top frame and the underframe.
In the utility model, between the upper and lower end of described upper and lower column stiffener and its place column a bit of distance is arranged respectively.And the upper and lower column stiffener of the described column of each root preferably is connected with underframe with corresponding top frame by two bolts respectively.
In the utility model, also be equipped with respectively in four bights of frame lower surface inboard, described top and be used for the top frame stiffener that is connected with the upper pillar stand stiffener; Also be equipped with respectively in four bights of described underframe upper surface inboard and be used for the underframe stiffener that is connected with the lower pillar stand stiffener.In addition, at four interior angle frame places of described underframe the fixed head concordant with the underframe lower surface is housed respectively also.
The utility model general instrument rack is simple for structure, and the production of single member and whole rack have assembling all very convenient; A plurality of mounting interfaces are arranged on the rack, and the process and assemble precision guarantees easily, is fit to large-scale production.

Fig. 5 is the upward view of the frame of top shown in Fig. 2;
Fig. 6 is the B-B cutaway view of Fig. 5;
Fig. 7 is the vertical view of underframe shown in Fig. 2;
Fig. 8 is the C-C cutaway view of Fig. 7.
Embodiment
In preferred embodiment of the utility model, the primary structure of rack is still based on sheet metal component, but broken away from the frame structure of a large amount of welding formings, but based on digital control processing, its structure as shown in figures 1 and 3, its main member comprises top frame 4, underframe 8, column 1, front and back door-plate 10, side door plate 11, side mounting panel 16, blower module 12, mount bar 13 etc.
Fig. 3 and Fig. 4 show the structure of the column 1 of sheet metal process moulding in the present embodiment.As can be seen from the figure, this column 1 is to adopt a block plate to form through a few road bending operations, in order to be connected with underframe 8 with top frame 4, be welded with a column stiffener 2 respectively at the two ends up and down of column 1, leave certain clearance between the upper and lower end of this column stiffener and column 1, for example 2-5mm.
During assembling, two bolts of each bight inside plug-in mounting of difference at top frame 4 and underframe 8, these bolts pass the screw on the corresponding column stiffener, cooperate with the nut 3 of column stiffener inboard tighten after, column 1 and top frame 4, underframe 8 can be connected into an integral body, form the agent structure of rack.As seen, be to be connected with underframe with the top frame by bolt respectively here, thereby realize being connected between column and top frame and the underframe by upper and lower column stiffener.Wherein adopt two bolts to connect, both can guarantee bonding strength, can prevent that again column from producing rotation, makes things convenient for column 1 to position, thereby increased assembly precision.
As can be seen from Figure 2, in the present embodiment, column 1 and mount bar 13 have adopted the structure of separate type; Mount bar 13 is installed on the side mounting panel 16, can connect by screw between the two.This separate type has increased the assembling flexibility of general instrument rack, can adapt to different space requirements.
As can be known from Fig. 5 and Fig. 6, top frame 4 is a rectangular configuration, and its main body is welded by two crossbeams 5 and two curb girders 6.In addition, shown in the dotted line among Fig. 5, also be equipped with respectively in four bights of top frame 4 lower surface inboards and be used for the top frame stiffener 14 that is connected with the upper pillar stand stiffener; That is to say that during assembling, bolt will pass corresponding top frame stiffener 14 earlier, passes corresponding column stiffener 2 again, just cooperates with the nut 3 of column stiffener inboard then and tightens, this structure can further increase bonding strength.
As can be seen, the agent structure of underframe 8 and top frame 4 are identical from Fig. 7 and Fig. 8, and same agent structure can be used as top frame or underframe, thereby can simplify production procedure.Equally, shown in the dotted line among Fig. 7, also be equipped with respectively in four bights of underframe upper surface inboard and be used for the underframe stiffener 15 that is connected with lower pillar stand stiffener 2.In addition, at four interior angle frame places of underframe 8 fixed head concordant with the underframe lower surface 9 is housed respectively also, it can increase the supporting surface of rack, strengthens the support strength of rack.
