Described basal disc (4) is provided with dovetail groove (15).
In the dovetail face of described basal disc (4) right side panel (14) is housed.
Described balancing disk (5) and balancing weight (6) are after the counterweight adjustment is finished, and be locked on basal disc (4) by T shape screw (8).
On described basal disc (4) and the balancing disk (5) rule is installed.
The adjustable bascule of the crank connecting rod journal lathe that the utility model provides is to utilize the feed screw nut transmission principle to realize moving radially of balancing weight, can be accurately to the workpiece counterweight, and the counterweight effect is very good.
The utility model compared with prior art, advantage is:
1, this apparatus structure advantages of simple, installation, easy to operate, safe and reliable;
2, this device is easy to adjust, and counterweight is accurate, and once mounting can satisfy the counterweight requirement of multiple crankshaft workpiece;
3, this device has reduced processing cost, has improved the bent axle crudy, has alleviated labour intensity.

Fig. 1 is a structure connection diagram of the present utility model
Fig. 2 is that the A-A of Fig. 1 is to the structure connection diagram
Among the figure, 1-main shaft, 2-main spindle box, 3-round nut, 4-basal disc, 5-balancing disk, 6-balancing weight, 7-hexagon socket cap head screw, 8-T shape screw, 9-leading screw, 10-limited block, 11-fixed block, 12-adjusting pad, 13-cover plate, 14-panel, 15-dovetail groove;
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described
With reference to Fig. 1, Fig. 2, the adjustable bascule of a kind of crank connecting rod journal lathe mainly is made up of main shaft 1, main spindle box 2, round nut 3, basal disc 4, balancing disk 5, balancing weight 6, hexagon socket cap head screw 7, T shape screw 8, leading screw 9, limited block 10, fixed block 11, adjusting pad 12, cover plate 13, panel 14, dovetail groove 15; Its main shaft 1 connects main spindle box 2, and basal disc 4 is fixedly mounted on the main shaft 1 by round nut 3, and balancing disk 5 is installed on the basal disc 4, and basal disc 4 is provided with dovetail groove 15, and by rotational lead screw 9, balancing disk 5 can move radially.In basal disc 4 right side dovetail faces, panel 14 (as shown in Figure 2) is housed, is used to guarantee that balancing disk 5 steadily moves, stuck phenomenon can not occur.Balancing weight 6 (can make the balancing weight of the plurality of specifications that varies in weight) is fixed on the balancing disk 5 by hexagon socket cap head screw 7; Leading screw 9 is arranged between basal disc 4 and the balancing disk 5, right-hand member at leading screw 9 is provided with limited block 10, fixed block 11 and adjusting pad 12, limited block 10 and fixed block 11 have played the axial limiting effect of leading screw 9, adjusting pad 12 can effectively prevent to occur bending and deformation after leading screw 9 from installing, and guarantees the stationarity of leading screw 9 in rotation process.After the counterweight adjustment is finished, with T shape screw 8 that balancing disk 5 and balancing weight 6 is locked on basal disc 4, the security when rotatablely moving with main shaft 1 with the assurance bascule.Rearward end at basal disc 4 is provided with cover plate 13, and basal disc 4 rear portions are emptied, and are used to reduce own wt, but does not influence counterweight effect and self rigidity, effectively reduces the noise that produces in the rotation process when cover plate 13 is closed Gai Houke.
Design principle of the present utility model is that the weight of the crankshaft workpiece 1,2 of being processed is that (G1＜G2), the eccentric throw of rod journal is L1, L2, with this design balance device for G1, G2.(be example with the counterweight of two kinds of Different Weight crankshaft workpiece only here, the principle that designs more crankshaft workpiece counter weight devices is identical)
According to the above-mentioned condition eccentric couple of crankshaft workpiece as can be known
M1＝G1×L1 M2＝G2×L2
Can design the weight G4 of basal disc thus.Design principle: M4=G4 * L4＜M1, L4 are the distance of the center of gravity of basal disc to spindle centerline.If M4＞M1, can't satisfy the counterweight requirement of light industry spare 1.
The weight G5 of design balancing disk and the weight G6 (balancing weight can be made multiple weight specification according to actual conditions here, to make things convenient for counterweight) of balancing weight, design principle:
M4+M5+M6＞M2
M5＝G5×L5 M6＝G6×L6
(L5, L6 are the distance of the center of gravity of balancing disk, balancing weight to spindle centerline)
After the weight of having determined each part, we just can utilize this principle to calculate each workpiece of trim, and balancing weight is with distance that balancing disk moved (it is identical to calculate principle, in this omission), and on basal disc 4 and balancing disk 5, rule has been installed, can have intuitive and accurately been operated.
