Description
Technical field
The utility model relates to machining, manufacturing process and equipment technical field, particularly a kind of new type auto advanceable enlarged footing that is used to process the large diameter hole face.
Background technology
There are a lot of large-size box type parts in the oil-well rig product, as turntable, transmission case etc.These box parts great majority form by thin steel plate assembly welding, and the rigidity of workpiece itself is relatively poor, big and interior outer face (anchor ring) requirement processing of the size in hole.According to traditional processing method (referring to right figure), normally on large-size horizontal boring and milling machine (W200G, W250G, digital display lathe, non-Digit Control Machine Tool), carry out milling, hilted broadsword scraping.There is following technical problem:
1). axial force is bigger during owing to milling, and the workpiece vibrations are very big, and the processing rear surface is coarse, and easily smash blade, owing to W250G, W200G lathe are the digital display floor type boring machine, can't mill out the anchor ring of rule automatically simultaneously, it is more to connect the cutter position, connects the utmost point out-of-flatness of cutter position, and surface quality is relatively poor; And can't mill the seam anchor ring;
2). the cutting edge width is big during the hilted broadsword scraping, and cutting force is big, and Workpiece vibration is big, and white steel knife tool wearing and tearing are big, the cost height.Need strike the cutter head feed man-hour adding, working (machining) efficiency is low, and because the cutter alignment error, the end face that often scrapes is matrix or convex, and surface quality is poor, and last full blade polishing processing is because the cutting position is wide, and vibrations and noise are very big.
Because according to above-mentioned conventional method processing, crudy is poor, and inefficiency, has had a strong impact on the handling capacity of key equipment.
Summary of the invention
The utility model purpose provides a kind of new type auto advanceable enlarged footing that is used to process the large diameter hole face.
Specifically, new type auto advanceable enlarged footing, it is by housing (4), power shaft (1), ring gear (2), planetary gear (3), worm couple (5) leading screw screw pair (6), the moving quiet guide rail of guide rail (7) (8), cutter holder is formed, power shaft (1) is connected with housing (4), the engagement of pocket-wheel (3) and ring gear (2) and its output shaft are connected with worm shaft in the worm couple (5), leading screw screw pair (6) is positioned at the worm gear snail, and to catch up with the outer and turbine screw of pair (5) be one, (7) one on moving guide rail and leading screw are rigidly connected, other end and cutter holder are rigidly connected, and quiet guide rail (8) is positioned at moving guide rail (7) and is connected with housing (4).
It is 1 that one side rails face of quiet guide rail (8) has increased gradient along its length: the inclined-plane of 60-100, having designed gradient between moving simultaneously guide rail and the quiet guide rail is 1: the panel of 60-100 is complementary with it, attachment screw of panel end band.
The planetary gear place is flooding system lubrication, by an amount of lubricating oil of oil filler point filling at gear ring place; The sliding friction surface of worm gear and worm gear bearing and dynamic and static dovetail groove adopts cascade oiling; All the other positions are all adopted manually lubricated; Taper shank power shaft and ring gear end face adopt the V-shaped seal ring sealing; Dynamic and static guide rail end surface is added with the felt that prevents smear metal damage guide rail.
The utility model has solved following technical problem: it makes the gyration of boring spindle form the automatic radial feed of cutter by the space combination of the reasonable novelty of a plurality of transmissions, thereby has realized the facing function of boring machine.1) application of this enlarged footing can reduce cutting force greatly, solves effectively or reduced on the large-sized structural parts large diameter hole end face to add problems such as, machined surface quality difference big owing to the workpiece vibrations that the workpiece poor rigidity causes in man-hour; 2) after this enlarged footing is used,, only need to get final product cutter processing behind preset lead screw position and the cutting depth and survive, avoided the large diameter hole end face to add and adjusted this inefficient phenomenon of cutter head continuously man-hour, greatly improved working (machining) efficiency for a large diameter hole end face; 3) but use that the outer face survives in this enlarged footing time processing hole, for the inner face processing in hole, do not need operating personnel to enter operation in the workpiece repeatedly, improved efficient, also meet HSE standard and human-based management more, 4) but use that the outer face survives in this enlarged footing time processing hole, avoid hole end surface to add and connect cutter man-hour, the finished surface flatness does not reach problems such as requirement, improved product quality effectively, 5) use outer face in this enlarged footing machining hole, because the very big reduction of cutting force has reduced tool wear, has improved cutter life, also reduced simultaneously the sharpening repeatedly of cutter, these have all reduced production cost, 6) this enlarged footing can be used in combination by changing main shaft Morse taper shank axle and multiple boring machine, and its application can enlarge the processes scope of the numerous non-numerical control borer of many numbers of the enterprise.
This auto-feed formula enlarged footing compact conformation, reasonable in design, be connected simply with lathe, integral body is a machine tool accessories unit.
The utility model compared with prior art has the following advantages:
1), changed and optimized the processing mode of outer face in the large diameter hole;
2), enlarged the processing range of correlation type boring machine;
3), greatly reduce cutting force, the viewpoint from this operation has been reduced requirement to workpiece rigidity grade, avoided workpiece vibrations and the cutting noise in the process;
4), the original relatively processing mode of working (machining) efficiency had very big raising, the product processing quality remarkable improvement, production cost effectively reduces;
5), for the operator, mode of operation is greatly simplified, and is convenient and safe;
6), the novel structure uniqueness, for the research and development manufacturing of related accessories later on provides thinking and practical experience.
