The beneficial effect of the utility model bent axle conical surface woodruff key press-loading apparatus is to change manual operations into mechanically actuated, and, after press-fiting, press-fit woodruff key and whether meet specification requirement by the groove check passed through on the positioning sleeve, not only improved production efficiency, and guaranteed to press-fit quality.
Description of drawings
Fig. 1 is bent axle conical surface woodruff key press-loading apparatus structural representation of the present utility model.
The specific embodiment
Fig. 1 is bent axle conical surface woodruff key press-loading apparatus structural representation of the present utility model, and among the figure, 1 is base plate, 2 is top board, and 3 is bolt column, and 4 is cylinder, 5 is piston rod, and 6 is drift, and 7 is base, 8 is positioning sleeve, and 9 is jumper bar, and 10 is back-moving spring, 11 is limited block, and 12 is spacer pin, and 13 for passing through groove, 14 is woodruff key, and 15 is bent axle, and 16 is Woodruff key slots and keyways.As seen from the figure, the utility model bent axle conical surface woodruff key press-loading apparatus comprises frame and punching mechanism, under punching mechanism is placed in the frame, described frame comprises base plate 1, top board 2, double-screw bolt 3, cylinder 4, piston rod 5 and drift 6,4 double-screw bolts 3 are fixed as rigid frame with base plate 1 and top board 2, cylinder 4 is fixed on the top board 2, and connects drift 6 by piston rod 5; Described punching mechanism comprises base 7, positioning sleeve 8, jumper bar 9, back-moving spring 10, limited block 11 and spacer pin 12, described base 7 be shaped as a cuboid with located lateral cover installing hole and vertical jumper bar gathering sill, be installed with positioning sleeve 8 in the located lateral cover installing hole, positioning sleeve 8 endoporus bottom is provided with orientational cone-shaped surface, the orientational cone-shaped surface of positioning sleeve 8 and bent axle 15 outer conical surface match, positioning sleeve 8 hole walls tops offers by groove 13, and the woodruff key 14 after press-fiting on shape that should be by groove 13 and size and the bent axle 15 is complementary; Jumper bar 9 slides up and down along the jumper bar gathering sill from base 7 tops; Back-moving spring 10 is sleeved on the jumper bar 9 and contacts with base 7 tops and spacer pin 12 respectively, and spacer pin 12 is fixed on jumper bar 9 tops; Limited block 11 is arranged on spacer pin 12 tops and is fixed on the base 7.
As shown in Figure 1, bent axle conical surface woodruff key press-loading apparatus of the present utility model in use, first bent axle 15 being passed positioning sleeve 8 inserts in the located lateral cover installing hole, rotary crankshaft 15 makes the Woodruff key slots and keyways 16 on the bent axle 15 align with the groove 13 that passes through on the positioning sleeve again, then, woodruff key 14 is positioned on the Woodruff key slots and keyways 16, restart cylinder 4, cylinder 4 promotes drift 6 by piston rod 5 and impacts jumper bar 9, jumper bar 9 compression reseting springs 10 are knocked in Woodruff key slots and keyways 16 with woodruff key 14, realize thus the process that press-fits of bent axle conical surface woodruff key press-loading apparatus of the present utility model; Drive drift 6 by piston rod 5 behind cylinder 4 counteragents and promote return, its jumper bar 9 also promotes under the drive of the reset force of back-moving spring 10 and breaks away from woodruff key 14, until the spacer pin 12 on the jumper bar 9 is run into till the limited block 11, jumper bar 9 also is returned to the home position, this process is the return process of bent axle conical surface woodruff key press-loading apparatus of the present utility model, by the overall process of repeatedly implementing to realize bent axle conical surface woodruff key press-loading apparatus of the present utility model mass production that press-fits process and return process.
