One end of the back moving spring is positioned on the stud of the locator, the other end is connected with the moderate planker, and the upper slider of the moderate planker is connected with the outside of the lathe through the back moving spring, so the roller contacts with the profile. The device is of low manufacturing cost, facility setting, safe and reliable processing.
Description
One, technical field
The utility model relates to a kind of copying apparatus of processing the disc cams shaped face, belongs to the machining equipment technical field.
Two, background technology
Usually, the working face of disc cams is made up of a plurality of curved surfaces, and cam and axostylus axostyle are assembled into cam assembly after split processing.The center of circle of each working curved surface of disc cams does not overlap with the axial line of axostylus axostyle usually, and these curved surfaces are exactly typical shaped face.The common method of processing these cam working faces has: carry out Milling Process with CNC milling machine, the pattern of utilization and cam consistent size carries out copying on lathe.Use lathe turning processing, camshaft on the automotive brake is made up of processing all-in-one-piece cam and axostylus axostyle, its cam belongs to this big class of disc cams, but the working face of cam is made up of two curved surfaces and two planes, it is a kind of shaped face of complexity, the axostylus axostyle of camshaft is also longer, and therefore, the cam of this camshaft can not utilize the pattern with the cam consistent size to carry out copying on lathe or process with numerical control turning.At present, the cam of this class automotive brake camshaft all adopts CNC milling machine or the processing of dedicated cam milling machine.
Adopt the complicated shaped face of CNC milling machine processing disc cams, though working (machining) efficiency height, but because the nc program of cam generally adopts manual establishment, its shortcoming is that the CNC milling machine software translating adopts linear interpolation, for straight line connects,, can't obtain enough coordinate points between characteristic point because of the limitation of manual programming mode, with regard to the cam contour after causing processing certain deviation is arranged like this, cause cam face rib to occur connecing, cunning has some setbacks.If pattern adopts bigger angle for carrying out calibration at interval, bigger at interval, data can not directly be used, if the programmer carries out manual interpolation refinement to cam contour, then programming is complicated, and workload is too big, and data check and correction difficulty, easily make mistakes.
Adopt the complicated shaped face of dedicated cam milling machine processing disc cams, because the monopoly of equipment, its versatility is not high, is unfavorable for that many kinds pass through.
Simultaneously, no matter adopting CNC milling machine still is the cam of dedicated cam milling machine processing automobile brake-toggle shaft, and the equipment funds input in its early stage is all bigger, and the product fixed cost is shared more, causes the manufacturing cost height.
Three, summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of copying apparatus of processing disc cam complicated abnormal shape curved surface on engine lathe is provided, and adopts this device machining cam, can guarantee that product processing quality can reduce the equipment funds input again.
The copying apparatus of the utility model processing disc cams shaped face, it is made up of four parts such as profiling bar, pattern body, take-up device and securing members.Wherein, profiling bar is made up of roller shaft, roller, roller location-plate, riser and securing member etc.; Take-up device is made up of return spring, column, positioning seat and securing member etc.; Pattern is according to the cam profile manufacturing, and the appearance and size of pattern is bigger than the appearance and size of cam.
The pattern body is connected with scroll chuck on the lathe, riser is connected with middle carriage on the lathe, the riser top is provided with the roller location-plate, connect by roller shaft between roller location-plate, the roller, positioning seat is connected with saddle on the lathe, and an end of return spring is contained on the column of positioning seat, and the other end is connected on the middle carriage, return spring links to each other middle carriage upper strata slide block with the lathe outside, roller is contacted with the pattern body.
Adopt the beneficial effect of technique scheme to be:
1, the low cost of manufacture of this device, debugging is easy, service behaviour is safe and reliable;
2, the pattern of this device is processed on numerical control device, and making is easy, machining accuracy is higher, can satisfy the requirement on machining accuracy of automotive brake camshaft;
3, engine lathe is done change seldom and this device is installed is just become camshaft processing special plane, its working (machining) efficiency is higher, and the surface flatness of institute's converted products also can meet the demands; After the product completion of processing, remove this copying apparatus, can recover to become engine lathe, bring into play the purposes of engine lathe again, can accomplish special, general dual-purpose, thereby made full use of enterprise's existing equipments resources, reach the purpose that reduces production costs.
Four, description of drawings
Fig. 1 is the structural representation of the copying apparatus of the utility model processing disc cams shaped face.
Among the figure: 1-roller shaft, 2-roller, 3-roller location-plate, 4-riser, 5-pattern body, 6-lathe tool, 7-return spring, 8-column, 9-positioning seat, 10-saddle, 11-middle carriage, 12-upper slide rest, 13-camshaft, 14-scroll chuck, 15-lathe.
Five, the specific embodiment
Be described in further detail below in conjunction with the copying apparatus of accompanying drawing the utility model processing disc cams shaped face:
The copying apparatus of the utility model processing disc cams shaped face, it is made up of four parts such as profiling bar, pattern body 5, take-up device and securing members.Wherein, profiling bar is by roller shaft 1, roller 2, roller location-plate 3, riser 4 and tightly form with part etc.; Take-up device is made up of return spring 7, column 8, positioning seat 9 and securing member etc.; Pattern body 5 is according to the cam profile manufacturing, and the appearance and size of pattern body 5 is bigger than the appearance and size of cam.
When using this device, the spiral shell of two M10 * 22 on the middle carriage 11 and the screw of M10 * 26 are backed out, the copper nut and the middle carriage 11 that match with horizontal feed screw mandrel are thrown off, take out middle carriage 11 leading screws of lathe; Profiling bar at middle supporting plate 11 left sides of lathe assembling band roller 2 links into an integrated entity profiling bar and middle carriage 11; Riser 4 links to each other with middle carriage 11 by bolt; Positioning seat 9 by bolted on saddle 10, one end of return spring 7 is loaded on the column 8 of positioning seat 9, the other end is fixed by bolts on the lathe middle carriage 11, like this, return spring 7 couples together the middle carriage 11 upper strata slide blocks and the lathe outside, and roller 2 is contacted with pattern body 5 all the time; Pattern body 5 is contained in by bolt on the scroll chuck 14 of lathe, the bar portion of scroll chuck clamp cam axle 13, the angle of adjustment camshaft 13 makes camshaft 13 consistent with the phase place of pattern body 5.In process, camshaft 13 and pattern body 5 are done coaxial rotatablely moving with main shaft, make the cam after the processing consistent with the phase place of pattern body 5; The lengthwise movement that profiling bar is done along lathe spindle with saddle 10 with take-up device realizes length feed; Realize traverse feed by upper slide rest 12.Like this, the cam profile that processes is exactly desired cam profile.
