Abstract

The utility model discloses a numerically controlled lathe special for processing the piston, and the topping mechanism comprises an explorator body (5), a camber grinding tool carrier (13) and a combined tool magazine (14). A piston lathe tool (18) with the elliptical face is arranged on the camber grinding tool carrier (13); a top surface lathe tool (17), a circular shore lathe tool (15) and a circular shore chamfer cutter (16) are arranged on the combined tool magazine. The workpiece can automatically process the elliptical surface, top surface, circular shore and circular shore chamfering under the controlling of a numerical control system, after clamping once; the mismachining tolerance caused by the repeated clamping is avoided; the machining accuracy and the productivity effect are rather high.

Description

Piston processing cnc lathe

[technical field] the utility model relates to a kind of lathe, particularly belongs to a kind of cnc lathe that is used for piston processing.

[background technology] piston is the key components and parts of engine, is the heart of engine, and the quality of piston directly has influence on the performance of engine.Under the technical conditions, the processing of piston is carried out on the multiple devices of machining production line at present, and operation is numerous and diverse, consuming time many, not only processing cost is higher relatively, and because workpiece needs repeatedly through clamping, takes off, the process of clamping, so machining accuracy again and workpiece quality are difficult to guarantee.

[summary of the invention] the purpose of this utility model promptly is to provide a kind of novel piston processing cnc lathe, finish multi-step process to reach on same chassis bed, reduce the mismachining tolerance of bringing because of clamping repeatedly, thus the purpose of raising workpiece quality and production efficiency.

Piston processing cnc lathe provided by the utility model, comprise lathe bed (10) and topping machanism, and by main motor (11), transmission mechanism (12), main spindle box (3), the PTO that main shaft (4) is formed, by digital control system (2), the electrical control gear that servo-drive system and forceful electric power circuit are formed, by oil pump (19), oil pipe (21), magnetic valve (20), the hydraulic pressure automatic clamping device that hydraulic cylinder (1) is formed, by the guide rail that is provided with on the lathe bed (9), what be provided with on the guide rail vertically moves planker (8), the feed arrangement that the stepper motor (7) that horizontal moving slider (6) that is provided with on the planker and driving planker and slide block move is formed; It is characterized in that so-called topping machanism comprises the pattern body (5) that is installed on spindle nose, is loaded into paranorm knife rest (13) and combination tool magazine (14) on supporting plate and the slide block; Piston ellipsoid lathe tool (18) is installed on the paranorm knife rest (13); The combination tool magazine is provided with end face lathe tool (17), ring bank lathe tool (15) and ring bank chamfer cutter (16).

Use piston processing cnc lathe provided by the utility model, workpiece only needs a clamping, can under the control of digital control system, finish processing automatically to piston ellipsoid, end face, ring bank and ring bank chamfering, avoided the mismachining tolerance brought because of clamping repeatedly, therefore have higher processing precision, and automaticity and the high characteristics of production efficiency.

[description of drawings] accompanying drawing partly discloses specific embodiment of the utility model, is further described below in conjunction with accompanying drawing:

Fig. 1, the utility model front view;

Fig. 2, the utility model vertical view;

Fig. 3, paranorm knife rest and combination tool magazine structural representation;

Fig. 4, hydraulic pressure automatic clamping device schematic diagram.

[specific embodiment] as depicted in figs. 1 and 2, piston processing cnc lathe disclosed in the utility model, comprise lathe bed (10), and the PTO of forming by main motor (11), transmission mechanism (12), main spindle box (3), main shaft (4); The horizontal moving slider (6) that is provided with on planker (8), the planker by vertically moving of being provided with on the guide rail that is provided with on the lathe bed (9), the guide rail and drive planker and feed arrangement that stepper motor (7) that slide block moves is formed; Topping machanism comprises the pattern body (5) that is installed on spindle nose, is loaded into paranorm knife rest (13) and combination tool magazine (14) on supporting plate and the slide block.

As shown in Figure 3, on the paranorm knife rest of the present utility model (13) piston ellipsoid lathe tool (18) is installed; The combination tool magazine is provided with end face lathe tool (17), ring bank lathe tool (15) and ring bank chamfer cutter (16).

As shown in Figure 4, the hydraulic pressure automatic clamping device of forming by oil pump (19), oil pipe (21), magnetic valve (20), hydraulic cylinder (1).Because of belonging to public prior art, so do not do too much explanation.

The utility model also comprises the electrical control gear of being made up of digital control system (2), servo-drive system and forceful electric power circuit." the CNC2000 liquid crystal display CNC system for lathe " that numerical control and servo-drive system can adopt " Hefei Da Lin numerical control device factory " to produce.Because of this part belongs to the technology contents that the technical staff of prior art and medium level can finish, so do not do too much explanation.

Lathe is stepped on floor push after starting, and the control hydraulic cylinder piston rod stretches out, and workpiece is placed on the pattern body, unclamps floor push, and the hydraulic pressure clamping device can realize that the location clamps automatically, the circulation of promptly starting working then.At first, finish the ellipsoid of the imitative car piston of pattern by the length feed of three-dimensional paranorm knife rest and planker, the time spent is because of the piston slightly difference that varies in size, and on average approximately needs for 10 seconds.Then, end face lathe tool, ring bank lathe tool and the ring bank chamfer cutter with the combination tool magazine cooperates the traverse feed of slide block to finish the car piston-top surface again, needs for 6 seconds approximately; Che Huanan needs 2 seconds of time spent approximately; Car ring bank chamfering needs 2 seconds of time spent approximately; Processing promptly comes to an end, and steps on floor push again, and the control hydraulic cylinder piston rod stretches out, and takes off workpiece and gets final product.
