Abstract
The utility model discloses a lathe jig for processing concentric holes of a rotating shaft, which adopts the structure that a bracket is arranged on the lathe jig; a pair of V-shaped blocks are arranged on the bracket; rectangular blocks with the identical structures are respectively arranged at two ends of the bracket; the bracket is mounted in a rectangular hole of a disc chuck of the lathe through the rectangular blocks arranged at the two ends of the bracket; the rectangular blocks are in clearance fit with rectangular hole on the disc chuck; the processed workpieces are positioned on each V-shaped block, and are compressed tightly by a pressure plate; so that end holes at two ends of each workpiece can be processed on the jig, and the coaxiality of the shaft holes at the two ends canbe ensured.
Description
Technical field:
The utility model relates to a kind of turning attachment of processing high-voltage breaker mechanism part-rotating shaft coaxial aperture, belongs to the Machining Technology field.
Background technology:
The coaxial aperture processing method of traditional irregular rotating shaft class part is normally: earlier with lathe claw folder workpiece one end, another stomidium of car is a benchmark with machining hole then, processes the stomidium of a remaining end.The anchor clamps that this processing method adopted mainly contain disk 1, mandrel 2, pressing plate 3, double-screw bolt 4, nut 5 compositions as shown in Figure 2.Mandrel 2 and disk 1 interference fit, pressing plate 3 connects together with disk 1 by double-screw bolt 4, nut 5.Add man-hour, earlier clamp the workpiece cylindrical end with scroll chuck, turning one stomidium A goes up anchor clamps then, lathe chuck centering mandrel 2, and with the A hole of workpiece and the workpiece cantilever end face location of going forward, the front boom of pressing plate 3 workpiece pressings gets final product another stomidium of car B.This anchor clamps are from design principle, A hole and cantilever end face location, except that around mandrel 2 rotary freedoms are not limited, all the other 5 direction frees degree all are limited, and design is correct, but at the elongated characteristics of workpiece, the B hole adds man-hour, and cutting force can not be big, otherwise, workpiece can produce moderate finite deformation adding man-hour, and two stomidium axialities can't be guaranteed.
Summary of the invention
In view of the problem of above-mentioned existence, the purpose of this utility model provides a kind of work efficiency height, and is simple in structure, and can effectively guarantee the turning attachment of the rotating shaft coaxial aperture of irregular rotating shaft class part coaxial aperture machining accuracy.
For achieving the above object, the utility model has been taked following technical measures:
The utility model has designed a support, on support, be provided with a pair of V-block, the two ends of support are respectively arranged with the pane of same structure, support is installed in by the pane that is arranged at two ends in the oblong aperture of lathe floral disc, and the oblong aperture on pane and the floral disc is matched in clearance; Processed workpiece is located on V-block, and compresses with pressing plate; Compress a little as close as possible cutting point, to improve the ability that anchor clamps bear cutting force; Like this, the stomidium at workpiece two ends can both be processed on anchor clamps, and can guarantee the axiality of two ends axis hole.

Fig. 2 is the turning attachment structural representation of existing rotating shaft class part coaxial aperture processing
Fig. 3 is a structural representation of the present utility model
Fig. 4 is that the utility model A is to the structure for amplifying schematic diagram
The turning attachment that workpiece two stomidium axialities can guarantee easily,
Wherein: 1-disk 2-mandrel 3-pressing plate 4-double-screw bolt 5-nut 6-floral disc 7-V type piece 8-support 9-V type piece 10-double-screw bolt 11-screw 12-pressing plate 13-alignment pin 14-screw
The specific embodiment:
A kind of turning attachment of processing the rotating shaft coaxial aperture described in the utility model, be provided with a support 8, on support 8, be provided with a pair of V- block 7,9, the two ends of support 8, be respectively arranged with pane C, the D of same structure, support 8 is installed in by the pane that is arranged at two ends in the oblong aperture of lathe floral disc 6, and the oblong aperture on pane C, D and the floral disc is matched in clearance; Processed workpiece is located on V- block 7,9, and compresses with pressing plate 12; Compress a little as close as possible cutting point, to improve the ability that anchor clamps bear cutting force.
During work,, processed shaft-like workpiece is placed on the V- block 7,9 earlier with lathe chuck centering and clamp floral disc 6, rotary pressure plate 12, and by the nut on the double-screw bolt 10 processed shaft-like workpiece is compressed.Like this, get final product the stomidium of turner one end.After the stomidium for the treatment of an end processes, unclamp screw 11, support 8 other end panes are inserted in the oblong aperture of floral disc 6, trip bolt 11 can be processed the stomidium of the other end.In addition, on the anchor clamps balancing weight can be set, operate steadily when making workpiece processing.This anchor clamps rigidity is better, and 12 pairs of Work-sheet pressing power of pressing plate are arranged near the cutting point, avoid the distortion of workpiece in machining.On the other hand, turning processing back A, B hole axiality depend primarily on the precision of anchor clamps itself, and the anchor clamps accuracy of manufacture can be guaranteed easily by Precision Machining (as be careful silk thread cutting, machining center Numerical control cutting).
