Abstract
The invention discloses a special fixture for milling an automobile reverse gear shaft, which comprises a baseplate fixedly arranged on a worktable, a fixed plate and a hydraulic cylinder are respectively and fixedly arranged on the left end and the right end of the baseplate, a left mounting plate and a right mounting plate are respectively and fixedly arranged on the left and the right ends of the fixed plate, a connecting shaft is fixedly arranged between the left and the right mounting plates, at least two clamp splices are movably sleeved on the connecting shaft, and the piston rod of the hydraulic cylinder is penetrated through the right mounting plate to be propped against one clamp splice arranged at the rightmost end. The invention has the advantages that: the clamping is convenient so that the automobile reverse gear shaft can be well fixed and conveniently milled, the working efficiency is high, the clamping position of a workpiece is the same at each time, tool setting does not need to be frequently carried out, and the operation is simple.
Description
Technical field
The present invention relates to a kind of anchor clamps that when automobile reverse gear shaft is carried out Milling Process, use.
Background technology
When automobile reverse gear shaft is carried out Milling Process, need earlier the automobile reverse gear shaft clamping to be fixed.Existing clamping method is original manual clamping, utilizing pressing plate and bolt that automobile reverse gear shaft is pulled by the operator is fixed on the workbench, clamping gets up very inconvenient, inefficiency, simultaneously, because therefore the position difference of each clamping workpiece all needed to carry out tool setting before automobile reverse gear shaft is carried out Milling Process at every turn, complex operation, inefficiency.
Summary of the invention
Technical problem to be solved by this invention is: the special fixture for milling automobile reverse gear shaft that a kind of convenient mounting and clamping is provided.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: special fixture for milling automobile reverse gear shaft, comprise: be fixedly installed on the base plate on the workbench, left side at base plate, be set with fixed head and hydraulic jack respectively on the right two ends, left side at fixed head, be set with left installing plate and right installing plate respectively on the right two ends, between left installing plate and right installing plate, be set with connecting axle, movable sleeve is provided with at least two fixture blocks on connecting axle, the piston rod of hydraulic jack passes right installing plate and offsets with a fixture block that is arranged on low order end, the lower end of fixture block is slidingly arranged on the fixed head, be respectively arranged with the half module groove that cooperatively interacts on the correspondence position mutually in adjacent fixture block upper end, on the connecting axle between the adjacent fixture block, be arranged with spring respectively, be respectively arranged with the cavity that cooperatively interacts on the correspondence position mutually at adjacent fixture block middle part, the two ends of spring are separately positioned in the cavity.
In order to solve the problems of the technologies described above better, the further technical scheme that the present invention adopts is: movable sleeve is provided with five fixture blocks on described connecting axle.
Advantage of the present invention is: the special fixture for milling automobile reverse gear shaft convenient mounting and clamping of this structure, can automobile reverse gear shaft is fixing well, and conveniently automobile reverse gear shaft is carried out Milling Process, high efficiency, the position of each clamping workpiece is identical, does not need frequent tool setting, and is simple to operate.
Description of drawings
Fig. 1 is the structural representation of special fixture for milling automobile reverse gear shaft of the present invention.
Fig. 2 is the plan structure schematic diagram of Fig. 1.
Among the figure: 1, base plate, 2, fixed head, 3, hydraulic jack, 31, piston rod, 4, left installing plate, 5, right installing plate, 6, connecting axle, 7, fixture block, 8, the half module groove, 9, spring, 10, hold-down screw, 11, cutter.
The specific embodiment
Describe particular content of the present invention in detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1 and Figure 2, special fixture for milling automobile reverse gear shaft, comprise: be fixedly installed on the base plate 1 on the workbench, on the left and right two ends of base plate 1, be set with fixed head 2 and hydraulic jack 3 respectively, on the left and right two ends of fixed head 2, be set with left installing plate 4 and right installing plate 5 respectively, be set with connecting axle 6 between left installing plate 4 and right installing plate 5, movable sleeve is provided with at least two fixture blocks 7 on connecting axle 6.In the present embodiment, movable sleeve is provided with five fixture blocks 7 on described connecting axle 6, and the number of fixture block 7 can be provided with arbitrarily when reality is used as required.The piston rod 31 of hydraulic jack 3 passes right installing plate 5 and offsets with a fixture block 7 that is arranged on low order end, the lower end of fixture block 7 is slidingly arranged on the fixed head 2, on the mutual correspondence position in adjacent fixture block 7 upper ends, be respectively arranged with the half module groove 8 that cooperatively interacts, on the connecting axle 6 between the adjacent fixture block 7, be arranged with spring 9 respectively, be respectively arranged with the cavity that cooperatively interacts on the mutual correspondence position in adjacent fixture block 7 middle parts, the two ends of spring 9 are separately positioned in the cavity.
When the special fixture for milling automobile reverse gear shaft of said structure uses, as depicted in figs. 1 and 2, base plate 1 is fixed on the workbench by plurality of fixed screw 10.During work, four automobile reverse gear shafts that needs are carried out Milling Process are respectively put into as shown in Figure 1 in the die cavity.The piston rod 31 of control hydraulic jack 3 stretches out, the fixture block 7 that is arranged on low order end that piston rod 31 promotions offset with it, the a fixture block 7 compression springs 9 that are arranged on low order end promote other fixture block 7 successively, automobile reverse gear shaft in the die cavity is fixed, started 11 pairs of automobile reverse gear shafts that fix of cutter and carry out Milling Process.After machining, piston rod 31 withdrawal of control hydraulic jack 3, fixture block 7 returns to original position under the effect of spring 9 separately, the automobile reverse gear shaft in the die cavity is removed fixing, automobile reverse gear shaft is taken off from anchor clamps get final product successively.
