Description
Technical field
The utility model belongs to Machining Technology field, particularly relates to a kind of Double Tops cam milling apparatus for processing brake camshaft.
Background technology
Brake has the device making moving component (or movable machinery) deceleration, stop or keeping the functions such as halted state.The machine components making the movement parts in machinery stop or slowing down.Be commonly called as brake, lock.Brake is primarily of compositions such as frame processed, brake component and manipulation devices.Some brake is also equipped with the automatic regulating apparatus in brake component gap.In order to reduce braking moment and physical dimension, brake is contained on the high speed shaft of equipment usually, but the main equipment (as mine hoist, elevator etc.) higher to security requirement then should be contained on the slow-speed shaft of equipment working portion.
In brake, very important part is brake camshaft, current use widely also the structure of very important brake camshaft see Figure of description Fig. 3, this structure current automobile, passenger vehicle and truck uses very many parts, but require that crudy is high, require also very high to the symmetry of part and axiality, otherwise it is not in place to produce braking, or the phenomenon that brake response is blunt.Brake camshaft is mounted on axle housing, brake drum is mounted on core wheel, core wheel is arranged on half-axle conduit by bearing, Here it is automotive axle, good brake camshaft can balancing brake vehicle bridge, eliminate the running stress unbalance loading of traveling mechanism and stress is concentrated, the carrying quality maintaining vehicle bridge is to greatest extent saved money, save time, cost performance is high.But existing process technology not can solve the axiality of brake camshaft in process and the problem of symmetry.
Utility model content
For solving the problems of the technologies described above, the utility model object is to provide a kind of Double Tops cam milling apparatus for processing brake camshaft.
Scheme of the present utility model is as follows:
For processing a Double Tops cam milling apparatus for brake camshaft, comprise slide unit, lower slide unit, dividing head, chuck and cylinder, described lower slide unit is provided with slide unit; Described upper slide unit top is provided with dividing head, is provided with holder on the left of upper slide unit; Described dividing head rear end is provided with cylinder block, and cylinder block rear end is connected with cylinder, and dividing head front end is provided with rolling center, and rolling center is outside equipped with chuck; Described cylinder is connected with push rod, and push rod is connected with rolling center through dividing head; Described holder is provided with stationary center; The center line of described stationary center, rolling center, chuck and push rod is positioned on same level line.
Described dividing head is fixed on upper slide unit below by horizontal mobile device.
Described dividing head side is provided with longitudinal moving device.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further;
As depicted in figs. 1 and 2, a kind of Double Tops cam milling apparatus for processing brake camshaft, comprises slide unit 6, lower slide unit 7, dividing head 5, chuck 3 and cylinder 9, and described lower slide unit 7 is provided with slide unit 6; Described upper slide unit 6 top is provided with dividing head 5, is provided with holder 8 on the left of upper slide unit 6; Described dividing head 5 rear end is provided with cylinder block 11, and cylinder block 11 rear end is connected with cylinder 9, and dividing head 5 front end is provided with rolling center 2, and rolling center 2 is outside equipped with chuck 3; Described cylinder 9 is connected with push rod 10, and push rod 10 is connected with rolling center 2 through dividing head 5; Described holder 8 is provided with stationary center 1; The center line of described stationary center 1, rolling center 2, chuck 3 and push rod 10 is positioned on same level line.
Described dividing head 5 is fixed on upper slide unit 6 below by horizontal mobile device 12, slide unit 6 can be made to carry out transverse shifting, milling cutter 14 place workpiece 4 being delivered to processing processes, horizontal mobile device 12 is made up of handwheel and carriage release lever, carries out adjustment dividing head 5 advance, retreat by hand handwheel.
Described dividing head 5 side is provided with longitudinal moving device 13, can vertically move dividing head 5, makes workpiece 4 be positioned at suitable position, and manipulation milling cutter 14 is processed.
Described holder 8 is provided with cushion block 15 below, highly can adjust cushion block 15, and stationary center 1 is positioned on same level line with the center line of rolling center 2, chuck 3 and push rod 10.
As shown in Fig. 3, Fig. 4 and Fig. 5, described workpiece 4 is brake camshafts, is widely used on automobile, passenger vehicle and truck; This part plays very important effect for car brakeing, and current manufacturing process is difficult to the axiality ensureing brake camshaft, and in process, easily occur that work centre line is beated, also very large on the symmetry impact of the cam cutting of brake camshaft.The utility model is by first fixing one end with stationary center 1 workpiece 4, then drive push rod 10 that rolling center 2 is withstood the other end of workpiece 4 by cylinder 9, thus ensure that axiality, then clamped by chuck 3, this operation can ensure when clamping, axiality change is very little, by mobile longitudinal moving device 13 and horizontal mobile device 12, workpiece 4 is delivered to milling cutter 14 place of milling machine, process, in process, workpiece 4 be fixed all the time top 1 and rolling center 2 locate, chuck 3 ensure that chuck strength simultaneously, also ensure that the positioning action of stationary center 1 and rolling center 2 pairs of workpiece 4 simultaneously, ensure that in the process of processing, the axiality of workpiece 4 and symmetry.And this device processing parts quality is good, long service life, production efficiency is high.The patent of the patent No. 201320150499.5 can only solve the positioning action before work pieces process, but in process, the Double Tops pinnacle that can not realize workpiece tightly acts on, because milling cutter produces pressure in the process of workpiece, easily make workpiece variation, do not reach the positioning action of process, have impact on axiality and the symmetry of work pieces process requirement, very large to the quality influence of workpiece.And the device of the application can address this problem very well, benefit is considerable, has extraordinary marketing prospect.
Although give detailed description and explanation to detailed description of the invention of the present utility model above; but what should indicate is; we can carry out various equivalence according to conception of the present utility model to above-mentioned embodiment and change and amendment; its function produced do not exceed that description contains yet spiritual time, all should within protection domain of the present utility model.
