The specific embodiment

As shown in Fig. 3, Fig. 4 A-4D, the utility model provides a kind of rotary table, and this workbench comprises traversing carriage 7 and the rotation platform 8 be rotationally connected with this traversing carriage 7, and rotation platform 8 has plane, a top for place work piece 81.

The rotary table that the utility model provides, use procedure is as follows: during to steel plate bending, at first rotary table is moved to suitable position before bender, lift steel plate by two people simultaneously and roll over first curved 1 on bender, after folding as shown in Fig. 2 B, after bending, be placed on turntable, two people standing places are constant, by after Rotate 180 before and after bending plate °, folding second curved 2 on bender, after folding as shown in Figure 2 C, after bending, be placed on turntable, by Zhe tri-roads curved 3 after Rotate 180 before and after bending plate °, after folding as shown in Figure 2 D, all the other turning methods of operating are the same, form successively tetra-roads of shown in Fig. 2 E curved 4, five roads curved 5 of shown in Fig. 2 F and Fig. 2 G form six roads curved 6, this rotary table operates for two people, bending quantity is more, curved mouth can save time greatly towards different bending techniques, raise the efficiency, reduced labor strength, this turntable also can be used for the work that needs rotational workpieces to complete simultaneously, and as the large-scale workpiece line, workpiece, before processing, need be rule to workpiece calibration, reserved processing capacity.Usually workpiece is placed on fixing marking-off table, the line operative employee need enclose marking-off table while ruling and be rule, and wastes time and energy, as rule with turntable, directly the Arbitrary Rotation workpiece, remove the operation of walking about around workpiece from, greatly facilitate the work of line, saved the time; Rotation by rotation platform replaces artificial turning of work piece, and, curved mouth more for two people operations, bending quantity can save time greatly towards different bending techniques, raises the efficiency, and reduced labor strength, and have simple in structure, the characteristics that cost is low; This rotary table also can be used for the work that needs rotational workpieces to complete simultaneously.

On the basis of above-described embodiment, as shown in Fig. 3, Fig. 4 A, workbench also comprises rotating shaft 9 and is set in the bearing 11 in this rotating shaft 9, there is bearing block 71 on traversing carriage 7, rotating shaft 9 one ends are fixed on rotation platform 8 bottoms, the other end penetrates in traversing carriage 7 by bearing block 71, and bearing 11 is arranged on bearing block 71.Rotate flexibly, be easy to safeguard.Bearing can be selected single thrust bearing, can bear larger axial force.

As shown in Figure 4 D, in order to prevent rotating shaft bottom overhang, divide the generation moment of flexure, in the bearing block bottom, be fixed with fairlead 12, rotating shaft 9 is located in this fairlead 12.Like this, overhang out the part of bearing block 71 of rotating shaft 9 just is limited in fairlead 12, can not produce bending, the unfavorable effect of having avoided shaft bending to bring because of long-time the use.

As shown in Figure 4 D, in order to reduce the wearing and tearing of fairlead 12, reduce the replacement cost of spare part, be equipped with lining 13 in rotating shaft 9, lining 13 is between rotating shaft 9 and fairlead 12, rotating shaft 9 bottoms have for lining 13 being encapsulated in to the pressing plate 14 in fairlead 12, and pressing plate 14 is fixedly connected with rotating shaft 9 or is fixedly connected with fairlead 12.The present embodiment center platen 14 is fixed on rotating shaft 9 bottoms by bolt 15, between bolt 15 and pressing plate 14, packing ring 17 is installed, and its end face and fairlead bottom face are conflicted or are rotationally connected, specifically a ring-type gathering sill can be set on the pressing plate end face, place a plurality of balls in this gathering sill, the fairlead bottom face also arranges and is the groove shape, and ball is limited in the space that ring-type gathering sill and fairlead bottom groove surround, to increase flexibility in relative rotation between pressing plate and fairlead.Fairlead is fixed on the bearing block bottom, once the fairlead wearing and tearing just must be changed together with bearing block, causes waste of material, and after adopting lining, directly more resleeve gets final product, without the integrative-structure of changing bearing block and fairlead.Lining is processed by QT400, and fairlead and rotating shaft can select the 45# steel to process.

As shown in Fig. 4 A-4D, in order to alleviate the weight of turntable, guarantee the intensity of turntable simultaneously, rotation platform 8 comprises panel 82 and is fixed on a plurality of gussets 83 formations of panel 82 bottoms.

As the optimal way of the present embodiment, panel 82 is circular, and gusset 83 is along the radial distribution of this panel.Rotation platform middle body intensity is the highest, and can play a supporting role after rotating shaft is fixedly connected with.

As shown in Figure 4 D, for convenient, weld rotating shaft and improve fastness, gusset 83 bottoms are fixed with terminal pad 16, and terminal pad 16 bottoms are fixedly connected with rotating shaft 9.Contact area between roller end and terminal pad is larger, welds or adopt other to be fixedly connected with mode to be easier to fix.

As shown in Fig. 4 A, Fig. 4 C, traversing carriage comprises stake body 72 and is fixed at least three stop castors 73 of stake body 72 bottoms.Stop castor 73 is convenient to the rotary table integrated moving, and there is stopping function, when movable workbench behind appropriate location, the stop castor is pinned, can check by friction plate the rotation of castor, thereby be placed on reposefully on the bar folder platform or on bottom surface, even if also can not rotate with it when turning of work piece.

As shown in Fig. 4 A, Fig. 4 C, stake body 72 is formed by fixedly connecting by many beams 720, and the stake body profile is prism-shaped, and stake body has simple in structure, and stability is higher, is easy to make and lower-cost advantage.Gusset 83 and beam 720 all can adopt rectangular beam.

Finally it should be noted that: above each embodiment, only in order to the technical solution of the utility model to be described, is not intended to limit; Although with reference to aforementioned each embodiment, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: its technical scheme that still can put down in writing aforementioned each embodiment is modified, or some or all of technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the scope of each embodiment technical scheme of the utility model.
