Abstract
The present invention relates to a special-purpose machine for milling and cutting oil grooves on the end surface of a cross axle, which mainly comprises that a positioning block is arranged on a main oil cylinder, and a clamping oil cylinder of which the lifting rod faces the positioning block is arranged on the positioning block; a plurality of milling cutters are symmetrically arranged at the outer side of the positioning block, and the milling cutters are parallel to the tangent line of the end surface of a cross axle on the positioning block, and the moving direction of the positioning block. Therefore, the present invention has the advantages of reasonable and simple structure for a whole machine, low cost, convenient operation, high production efficiency, production of about 4000 per shift, convenient adjustment of variety replacement, lowered production cost, etc.
Description
Technical field
The utility model relates to a kind of metalworking machinery, especially relate to a kind of on cross axis faces the special-purpose machinery of milling oil groove.
Background technology
In order to improve the store oil ability of each spindle nose of Hooke's joint and shaft room, reduce the frictional resistance of moving row, need usually on each end face of cross axle, to mill out some oil grooves.For this reason, in process of production, need to adopt milling machine each end face of cross axle spindle nose one by one milling go out several oil grooves.For example, when the cross axle machining production line that adopts U.S. She Le company to make, though the equipment complexity, class only produces also about 800 usually, and the oil groove that mills out is circular-arc, and is very unreasonable.Therefore, it is not high to exist the production work efficiency, and equipment efficiency of usage is low, has improved the deficiencies such as processing cost of product.
Summary of the invention
Goal of the invention of the present utility model is to overcome the deficiencies in the prior art, provides a kind of rational in infrastructure, working (machining) efficiency height, the cross shaft face sump cutter of good economy performance.
Goal of the invention of the present utility model mainly is achieved by following technical proposals: master cylinder is provided with locating piece, and it is provided with the clamping cylinder of push rod towards locating piece; And be symmetrically arranged with some milling cuttves in the outside of described locating piece; And the tangent line of the cross axis faces on described milling cutter and the locating piece and the direction of motion of locating piece parallel.Wherein, described milling cutter is symmetric arrangement usually, for example two groups or four groups; The direction of its cutting is general unified be oriented suitable, promptly all down or all up.Like this, each milling cutter reaches balance in the power of the various horizontal directions that cutting the time is produced, and is beneficial to and simplifies mechanical mechanism, improves the quality of products and improves work efficiency.Described milling cutter can adopt existing various suitable motor, transmission mechanism, hydraulic machinery etc. to be used as power and drive separately or unit transmission driving.
Goal of the invention of the present utility model can also further be able to perfect by following technical proposals: symmetric arrangement has four groups of milling cuttves by the motor drive on described workbench, and the cutting direction of described milling cutter is downward.This both had been beneficial to and had prevented that iron filings from disorderly flying everywhere, and its downward cutting force also is beneficial to the downward operation of master cylinder.
In addition, in order once whole cutting to make some oil grooves on four end faces of workpiece, described milling cutter can be provided with some groups of cutter blades parallel to each other.The width of cutter blade is decided according to the design width of required oil groove, and the distance between each cutter blade can be set according to the setting spacing of oil groove.And in described locating piece, be provided with criss-cross V-type groove, can be convenient to the location of workpiece on locating piece greatly.Usually, in process of production, only need workpiece arbitrarily is positioned on the locating piece, along with the clamping of clamping cylinder push rod, workpiece is a fix in position.
Therefore, the utlity model has said device features rational structure, simple, cost is lower, and is easy to operate, the production efficiency height, and class produces and reaches about 4000, and it is comparatively convenient to change the kind adjustment, thereby characteristics such as reduces production costs greatly.
Description of drawings
Accompanying drawing 1 is the vertical view of a kind of part of the present utility model;
Accompanying drawing 2 is a kind of structural representations with part section of the present utility model.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: be symmetrically arranged with four groups of milling cuttves 8 and driving mechanism thereof on tetragonal workbench 1, it mainly is by motor 9, constitutes by belt pulley 11 and main spindle box 12, and drives the milling cutter 8 that is arranged at main spindle box 12 ends independently thus.Described milling cutter 8 is made of the cutter blade of three equi-spaced apart, and the line at its center is cross.Below workbench 1, be provided with electric control cabinet 13 and master cylinder 10.Master cylinder 10 passes through its pull bar 2, and is connected with the locating piece 4 of portion provided thereon through fairlead 3.Wherein, be provided with criss-cross V-type groove 40 in the described locating piece 4.And be provided with a square hole 15 at the central area of workbench 1, so that the Hooke's joint (workpiece) that locating piece 4 drives portion placed on it moves up and down under the driving of master cylinder in good time, finish milling and cut.In addition, described locating piece 4 is provided with support, which is provided with push rod 7 clamping cylinder 7 down.
During production, primer fluid press pump 16 and motor 9 are in hydraulic system and treat duty respectively.Then cross axle 15 is placed on the locating piece 4, opens clamping cylinder 7, its push rod 6 is ejected downwards, be pressed on the central portion of cross axle 15, make to be positioned at comparatively exactly on the locating piece 4 that has V-type groove 40.The pull bar 2 of master cylinder 10 shrinks, four ends of cross axle 15 are vertically moved, and average rate moves down under the milling of milling cutter 8 tangent with it, and its end promptly under the milling that the high speed of milling cutter 8 is rotated, mills out the oil groove that three groove depths and groove width all meet design requirement simultaneously on four end faces.After having milled, master cylinder makes pull bar 2, locating piece 4, push rod 6 and clamping cylinder 7 automatically restore to initial position by hydraulic drive, and push rod 2 unclamps simultaneously, and milling cutter 8 stops operating, and behind the taking-up workpiece, is reentered into cross axle 5, can repeat processing.
