The turning handle of a knife is impressed in the mounting groove, through screwing up the screw, fixes the turning handle of a knife, and the turning handle of a knife adopts the press-fixed formula to fix in the mounting groove. The invention can mount standard cutters at will in the horizontal and longitudinal directions, can meet the turning requirements of the excircle and the inner bore of the piston rod at the same time, guarantee the rigidity of the cutter system, the invention is easy to operate, and can be compatible with the existing standard turning cutters and most non-standard cutters.
Description
Technical Field
The invention relates to an auxiliary tool for machining a piston rod of a large-scale low-speed marine diesel engine, in particular to a turning tool rest used for machining an inner hole of the piston rod of the diesel engine.
Background
A piston rod of a large-cylinder-diameter low-speed marine diesel engine is made of a steel piece material and is of a revolving body structure, and an orifice of a central hole of a rod body is of a conical structure. The turning processing of the center hole product belongs to the heavy cutting range, and the existing standard type square tool holder with the specification of 30mm multiplied by 30mm cannot meet the heavy turning requirement no matter in length or rigidity of the tool holder. The traditional method that adopts welding extension handle of a knife length, though can satisfy the taper hole processing requirement in length, nevertheless because the handle of a knife overlength for the rigidity greatly reduced of whole cutter system, when carrying out the turning centre bore, the handle of a knife wholly vibrates and leads to cutting surface roughness not up to standard, and depth of cut improves limitedly, and processingquality and machining efficiency all are difficult to obtain guaranteeing, and often appear the handle of a knife because of the rigidity not enough takes place the cutter body and bursts apart, the handle of a knife is scrapped, can cause the undercutting accident even to the machined surface of work piece itself. Adopt traditional handle of a knife to reform transform the mode and carry out heavy cutting process, no matter the effect is all unsatisfactory on machining efficiency, processingquality, cutter consumption cost to the tool rest base easily takes place the cutting with the centre frame and interferes.
Disclosure of Invention
In order to solve the problems, the invention provides a composite anti-collision heavy turning tool rest, aiming at achieving the purposes of ensuring the rigidity of a tool system and avoiding the occurrence of cutting accidents caused by the cracking of a tool body and the scrapping of the tool handle due to insufficient rigidity of the tool handle, and the adopted technical scheme is as follows:
the utility model provides a heavy turning knife rest of compound anticollision, has knife rest main part and handle of a knife mounting member, the knife rest main part with handle of a knife mounting member passes through the tip and welds integratively, the knife rest main part with handle of a knife mounting member mutually perpendicular has the mounting groove along the structure trend of handle of a knife mounting member surface is opened, handle of a knife mounting member is kept away from threaded hole is opened to the one end of knife rest main part, and the screw passes the screw hole, the screw have with the external screw thread of screw hole looks adaptation, the turning handle of a knife is arranged in the mounting groove. The turning handle of a knife is impressed in the mounting groove, through screwing up the screw, fixes the turning handle of a knife, and the turning handle of a knife adopts the press-fixed formula to fix in the mounting groove.
In the above composite anti-collision heavy-duty turning tool holder, preferably, the threaded hole is arranged along the edge of the mounting groove. The screw passes the screw hole and contacts with the turning handle of a knife, screws up the screw, and the screw top is in turning handle of a knife department, fixes the turning handle of a knife in the mounting groove.
The composite anti-collision heavy-duty turning tool holder is preferably provided with 4 threaded holes. The number of threaded holes can be any number, and the purpose achieved by the threaded holes is to fix the turning tool shank.
Above-mentioned heavy turning tool holder of compound anticollision, preferably, the degree of depth of mounting groove is 35mm, the width of mounting groove is 70 mm. The mounting groove with the size can be used for better fixing the turning tool shank.
Preferably, the screw is an M16 internal hexagonal screw. The screw hole is an M16 screw hole by adopting an M16 internal hexagonal screw.
The invention has the beneficial effects that:
the lathe tool seat is clamped in a lathe tool seat of a horizontal lathe, standard tools can be freely installed in the transverse direction and the longitudinal direction (namely the X-axis direction and the Z-axis direction), the turning requirements of the outer circle and the inner hole of the piston rod can be met simultaneously, the rigidity of a tool system is ensured, the lathe tool seat is simple to operate, and the lathe tool seat can be compatible with the existing standard lathe tools and most non-standard tools.
Drawings
FIG. 1 is a schematic front view of the present invention;
FIG. 2 is a schematic bottom view of the present invention;
FIG. 3 is a longitudinal working view of the turning insert;
FIG. 4 is a working schematic view of the turning insert in a transverse direction;
wherein: 1-a knife rest main body, 2-a knife handle mounting component, 3-a threaded hole and 4-a mounting groove.
Detailed Description
The invention is further explained by combining the attached drawings, and the composite anti-collision heavy turning tool rest shown in the figures 1 and 2 comprises a tool rest main body 1 and a tool shank mounting member 2, wherein the tool rest main body and the tool shank mounting member are rectangular, the tool rest main body and the tool shank mounting member are mutually vertical and are welded into a whole, and the tool rest main body is of a solid structure and is beneficial to positioning and strengthening the strength of a tool system. The thickness of handle of a knife installation component is 30mm, and it has mounting groove 4 to open along handle of a knife installation component outside structure trend, and the mounting groove is whole to be "L" type, and the degree of depth of mounting groove is 35mm, and the width is 70mm, is applicable to the turning tool of various model specifications. By adopting the mounting groove with the structure, the turning tool can be ensured to work horizontally and longitudinally, namely, the turning tool can be randomly mounted with standard tools in the X-axis direction and the Z-axis direction in two directions, and the turning requirements of the excircle and the inner hole of the piston rod are met.
One end that the knife rest main part was kept away from to handle mounting member, the edge along the mounting groove is provided with screw hole 3, and the screw hole adopts M16 screw hole, cooperatees with hexagonal screw in M16, and hexagonal screw contacts with the turning handle of a knife in the M16 for fixed turning handle of a knife.
As shown in fig. 3 and 4, during work, the turning tool shank is pressed into the mounting groove, the turning tool can be vertically or horizontally mounted, the screw is screwed down to fix the turning tool, and then the whole tool rest is arranged in a tool rest base of a machine tool to perform inner hole and excircle turning processing on a workpiece.
The invention has simple structure and convenient operation, and can be compatible with the existing standard lathe tool and most non-standard tools.
