Further, base is fixed two axis of guides, two axis of guides and lower platen are slidably matched.
Further, top board is provided with four upper guide bush, and four upper guide bush are provided with the slide-bar hole coordinated one by one with four slide-bars respectively.
Further, lower platen is provided with four lower guide pin bushings, and four lower guide pin bushings are provided with the slide-bar hole coordinated one by one with four slide-bars respectively.
Further, four slide-bar upper ends connect a limited block respectively.
Compared with the prior art the utility model has the following advantages:
The utility model structure is simple, compact, reasonable, and cost is lower, easy to maintenance; Assemble simple and quick, improve production efficiency; Tool locating is accurate, ensure the gear assembly after press-fiting operationally gear almost without beating; Lower back-moving spring prevents from damaging workpiece and frock by pressure, overload protection safety, not part of damage; Assembly precision is high, and percent defective is low; Greatly save the muscle power of operating personnel, efficiency is high, is applicable to large batch of Assembling Production mode.

Detailed description of the invention
Embodiment in is by reference to the accompanying drawings further described by the utility model below:
As shown in Figure 1 and 2, the utility model mainly comprises base 11, and on base 11 4 jiaos, logical bolt connects four slide-bars 5, and base 11 center is bolted back-up block 10.
Jointly on four slide-bars 5 to connect between top board 2 and lower platen 8, four slide-bars 5 and top board 2, lower platen 8 for being slidably matched.
Described base 11 is fixed two axis of guides, 13, two axis of guides 13 to be slidably matched with lower platen 8, two axis of guides, 13 pairs of lower platens 8 play guide effect.
Described top board 2 is provided with four upper guide bush, 3, four upper guide bush 3 and is provided with the slide-bar hole coordinated one by one with four slide-bars 5 respectively.Described lower platen 8 is provided with four lower guide pin bushings, 7, four lower guide pin bushings 7 and is provided with the slide-bar hole coordinated one by one with four slide-bars 5 respectively.
In Long-Time Service process, top board 2 and lower platen 8 cause inner wall abrasion owing to sliding up and down on slide-bar 5 of being everlasting, and by increasing upper guide bush 3 and lower guide pin bushing 7, only needing the upper guide bush 3 of replacing wearing and tearing and lower guide pin bushing 7 to reuse, reducing maintenance cost.Meanwhile, top board 2 and lower platen 8 directly process slide-bar hole difficulty greatly, and precision is also not high enough, can be improved the machining accuracy in slide-bar hole by increase upper guide bush 3 and lower guide pin bushing 7.
Described four slide-bar 5 upper ends connect a limited block 1 respectively, and limited block 1 prevents top board 2 from the landing of slide-bar upper end.
Described four slide-bar 5 tops are set with a upper reset spring 6, and upper reset spring 6 is between top board 2 and lower platen 8 and compress top board 2 and lower platen 8.Four slide-bar 5 bottoms are set with a lower back-moving spring 9, and lower back-moving spring 9 is between lower platen 8 and base 11 and compress lower platen 8 and base 11.
As shown in Figure 2, described lower platen 8 upper surface center is provided with four locating pieces, 12, four locating pieces 12 and distributes along same even circumferential.Lower platen 8 upper surface is the supporting surface of assembling gear 14, and four locating pieces 12 are for positioning clamping assembling gear.
Described top board 2 lower surface center is provided with briquetting 4, being centrally located on same vertical line of briquetting 4, lower platen 8, back-up block 10 and base 11, and the center of briquetting 4, lower platen 8, back-up block 10 and base 11 is provided with the pilot hole for the assembled shaft 15 of assembling with assembling gear 14.
Operation principle of the present utility model is: as shown in Figure 3, when carrying out gear and axle assembly work, being arranged on by axle in the pilot hole of briquetting, gear being placed on lower platen upper surface.Then press down top board, top board drives assembled shaft in briquetting through the pilot hole of gear center hole and back-up block, base, and after assembled shaft is in place, by back-moving spring by top board return, now gear and axle have assembled.In assembling process, on top board, apply stable pressure F, under the effect of F, upper reset spring shrinks, top board drives briquetting to be pressed in assembled shaft, assembled shaft is moved press-in gear in pilot hole system, and when briquetting lower surface is pressed onto gear surperficial, assembled shaft upper surface just contacts with top board lower surface, assembled shaft terminates the motion being pressed into gear, between gear and axle, relative motion stops, and the position automatic in-position of gear in assembled shaft, precision is high.After pressing, slowly remove power F, under upper reset spring effect, top board and briquetting move upward to original position along slide-bar, conveniently take out the assembly pressed.Due to the existence of limited block, top board can not be caused to fly out under spring force impacts, ensure safety, when applied pressure F is excessive, lower back-moving spring shrinks and bore load, prevents from damaging workpiece and frock by pressure, overload protection safety.
