Description

Numerical control central sill combination drill lathe
Technical field
The present invention relates to the machine tool technology field, specifically a kind of numerical control central sill combination drill lathe that is mainly used in the boring of railway freight-car C70, C64K, NX70, X6K, 6N70,6Q70, ECH58, KM70, P64K, C80, NX80 type central sill and other special-shaped central sill.
Background technology
As far back as season in previous generation seven, eight, the nineties, six processing of accomplishing central sill of the most big radial drilling machine of employing of each vehicle producer.Need at least six employees, central sills upset just can machine for three times, this process makes that working strength of workers is very big, precision is unstable, efficient is also very low, and central sill of every processing will be used two hours.
In the beginning of this century, lathe manufacturer developed Ni Zhifu drill formula central sill combination drill lathe, was used to accomplish the processing of central sill afterwards.Though this process has alleviated working strength of workers, efficient increases (40 minutes/root), and precision is unstable, the location is also unstable.Especially " central sill " product is the core component of railway freight-car; Length at 13~17 meters, weight more than two tons; Owing to be that its flexibility of welding structural element and torsion resistance are all very big, 12 groups and 15 groups of holes are arranged respectively is four groups to the symmetric position of stringer board seat in the two ends front and back of central sill.When, the workman need disassemble many drill bits when meeting burning of bits head or drill bit and fractureing, lathe is shut down will be for a long time, the rate of starting of lathe can only reach 50%.Owing to reasons such as this process and machine tool structure restriction boring can not add cooling fluid, burning of bits head often takes place, the durability of cutter is difficult to guarantee again.Now, the economic develop rapidly of China, the market transportation demand amount of the various lorries of railway is very big.Its central sill size of different lorries, structure, hole are all different with pitch-row; Because part length is all above more than the 12m; Certainly exist distortion in various degree in the welding process, therefore, the related process technology of each side such as location, clamping, conveying is crucial; Phenomenon such as avoid taking place mutual interference, block, this just need advanced, have the processing that very high flexible and variable equipment is accomplished these central sills.
Summary of the invention
The central sill that the purpose of this invention is to provide a kind of disposable completion car body is formed the forward and backward stringer board seat hole at place, two ends, is gone up the numerical control central sill combination drill lathe of the boring of core dish hole, hook supporting plate hole, safe support plate hole; It is than former Ni Zhifu drill formula central sill combination drill lathe; Have that operation is concentrated, efficient is high, machining accuracy is high; What have more the advanced person is that novel numerical control central sill combination drilling machine of the present invention has very high flexibility, can satisfy the processing needs of all central sill products.
The objective of the invention is to realize like this: it includes gantry main body, lathe bed, wing base, conveying rod, anchor clamps, chip cleaner, filings collecting chamber; It is characterized in that: the complete symmetric arrangement in the vertical two ends of said lathe; Be fixed with gantry main body and anchor clamps on the lathe bed at two ends; Gantry main body is provided with a upright numerical control main axle box unit, and main body is provided with wing base in both sides longitudinally at gantry, two ends, and this wing base is provided with crouch a numerical control main axle box unit and the three-dimension numerical controlled slide unit that has single main spindle box; On the main body longitudinal centre line of gantry, two ends, also be evenly equipped with at least two conveying rollers, this conveying roller has a connection motor at least; Conveying roller includes sprocket wheel, rolling wheel support, roller and roller bearing, and this roller housing is contained on the roller bearing in the rolling wheel support, and rolling wheel support is fixed on the come-up kinetoplast; Following buoyancy body bottom is provided with guide post; This guide post cunning is inserted on the floating bracket, and floating bracket is provided with the vertical hydraulic oil cylinder, and the telescopic shaft of this vertical hydraulic oil cylinder is connected with following buoyancy body; At the globoidal structure that is slidingly connected between kinetoplast and the following buoyancy body that floats, the center of circle line of this cambered surface correspondence is vertical with roller bearing.
Described each main spindle box is provided with interior cryoprobe tool.
Described anchor clamps are on the vertical symmetrical centre of edge two gantry main bodys position, also to be provided with floating clamp to special-shaped anchor clamps, terminal fixture, main anchor clamps and the auxiliary clamp of longitudinal center's symmetric arrangement in two ends longitudinally along two gantry main bodys.
The both sides of main body longitudinal centre line are provided with guide roller at gantry, two ends.
Gantry, two ends main body longitudinal centre line is provided with and progresses greatly to mechanism; This progresses greatly to include to mechanism and vertically feeds oil cylinder, is sleeved on the guide post on the work supporting block, the telescopic shaft joining work pieces carriage of this hoist cylinder what vertically feed hoist cylinder that the oil cylinder upside connects through guide rail, the setting of hoist cylinder upside.
Conveying mechanism of the present invention adopts steady and stable reductor, chain drive, to guarantee the accurate position between part and the equipment, is provided with protection; The part raceway adopts the guiding mechanism of level and vertical direction, helps the stable transmission of central sill; Transmit central sill with the height that roller type supports, can adjust by product; Location and cramping adopt hydraulic drive.Beneficial effect of the present invention:
1, machine tool structure is novel, advanced, reasonable.
2, lathe material conveying road structure is advanced, steady, reliable.
