Abstract
The utility model provides an end face special-shape turning indexable cutter bar. The end face special-shape turning indexable cutter bar comprises a cutter body, a cutter bit, a fastening and adjusting element. The end face special-shape turning indexable cutter bar is characterized in that a sliding groove screw via hole is arranged on the position where the cutter bit is arranged at the front end of the cutter body. A fixing screw via hole is arranged at the other end of the cutter body. After the angle of the indexable cutter bit is adjusted by two hexagon socket head cap screws when the indexable cutter passes through the sliding groove screw via hole and the fixing screw via hole on the cutter body, the indexable cutter bit is connected with a cutter bit fastening screw hole which is arranged on the indexable cutter bit. Then the indexable cutter bit is arranged in an indexable cutter bit installation groove which is arranged on the cutter body. The end face special-shape turning indexable cutter bar is capable of overcoming the defects of a forming cutter. The installation angle of the cutter bit can be adjusted according to the machining need of different end face special-shape workpieces under the circumstance of being interfered by the angle of part of products and the cutter. The machined workpieces can meet the need of dimensional accuracy and planar coarseness. When the end face special-shape turning indexable cutter bar is applied to longitudinal numerically-controlled machine tool, machining of most workpieces with complicated shape end faces is achieved and machining range of the longitudinal numerically-controlled machine tool is widened.
Description
Technical field
The utility model relates to a kind of cutter, especially relates to a kind of autofeed CNC sliding headstock auto-lathe knife bar.
Background technology
Existing autofeed CNC sliding headstock auto-lathe, the knife bar that uses all is the general knife bar in the sample, because its cutter clamping mode is row's cutter mode arranged side by side, knife bar all is towards radially clamping of workpiece, so when the shape workpieces such as turning end abnormity annular groove, general knife bar just can not satisfy processing request fully.The part workpiece has to adopt molding cutter to be processed, and the method is not only to cutter and the to some extent requirement of workpiece shape, and dimensional accuracy and the face rugosity of workpiece also is difficult to reach requirement.
Summary of the invention
For above problem, the purpose of this utility model provides a kind of autofeed CNC sliding headstock auto-lathe knife bar, it can overcome the deficiency of molding cutter, can be in the situation of portioned product angle and blade angle interference, suitably adjust the setting angle of cutter head according to the processing request of different end face special-shaped workpieces, make the workpiece that processes satisfy dimensional accuracy and the requirement of face rugosity.
For achieving the above object, the utility model provides a kind of end face abnormity turning indexable knife bar, comprise cutter hub, cutter head, fastening and adjustment element, it is characterized in that, cutter hub 2 front ends are provided with sliding tray screw via hole 5 in the cutter head installation position, be provided with fixed screw via hole 6 at the other end, indexable cutter head 1 utilizes two hexagon socket head cap screws 4 to be connected the cutter head holding screw hole 9 of adjusting after the angle with on the indexable cutter head 1 with the fixed screw via hole through the sliding tray screw via hole 5 on the cutter hubs 2 to be connected, to be installed in the indexable cutter head mounting groove 8 on the cutter hub 2.Described cutter hub 2 also is provided with top wire hole 7 in both sides, cutter head installation position, the top wire hole 7 and indexable cutter head 1 close proximity of jackscrew 3 on cutter hub 2.
This knife bar has been considered the versatility of workpiece end face shape in design, in the Front-end Design of cutter hub sliding tray screw via hole and fixed screw via hole, the rotary cutter that is installed on the cutter hub can be in the situation of portioned product angle and blade angle interference, become flexible and the slip holding screw, adjust to the workpiece that the fastening rear processing of suitable angle has special-shaped end face.Jackscrew plays the effect of finely tuning and holding out against cutter head then by the top wire hole on the cutter hub.
The utlity model has following advantage and effect:
1, the lathe adjustment time obviously shortens, and the average accent bed time was 180 minutes in the past, shortened to now in 30 minutes.
2, surface quality obviously improves, and the workpiece that processed in the past obviously connects tool marks owing to be to squeeze to be whittled into type so have, and its workpiece face rugosity is difficult to reach perfect condition about RA0.8.What adopt now is Program path control, and the workpiece face rugosity that processes can reach RA0.2.
3, the product size precision is guaranteed, owing to use this Novel knife bar can adopt the path programming, therefore can adopt the tool nose radius compensation function, can guarantee the product size precision.

The specific embodiment
Shown in Fig. 1～6.It is to utilize two hexagon socket head cap screws 4 overleaf by sliding tray screw via hole 5 and screw via hole 6 by indexable cutter head 1 that this knife bar forms, be connected with two cutter head holding screw holes 9 respectively after adjusting to suitable angle, be installed in the indexable cutter head mounting groove 8 of cutter hub 2, pass through top wire hole 7 behind indexable cutter head mounting groove 8 interior vernier angles with jackscrew 3 again, locking hexagon socket head cap screw 4, last fastening good jackscrew 3 gets final product.When using with standard insert through blade holding screw hole 10 clampings to blade holding tank 11, be installed on the lathe and just can have used.
The material that knife bar uses is No. 45 steel, through modulation treatment, makes its rigidity and hardness all reach instructions for use.What blade used is 35 ° of blades of V-type, makes its versatility reach best.
Be equipped with this knife bar at the rip cutting Digit Control Machine Tool, substantially can realize that most of end faces are with the processing of the workpiece of complicated shape, widen the range of work of rip cutting Digit Control Machine Tool, as long as press universal cutter tool setting mode to good cutter, just can adopt track to programme processing work.
