The specific embodiment:
Shown in figure (1,2), comprise installing plate 1, diameter dish 2, wire rack 3, push rod cam 4, large fluted disc cam 5, driving shaft 6, dead axle 7, push rod carriage 8, fixture block linkage 9, briquetting hold down gag 10.
As shown in Figure 3, diameter dish 2 is made up of diameter dish 2a, diameter dish 2b and connecting plate 2c.Connecting plate 2c is embedded in the groove of diameter dish 2a and diameter dish 2b bottom, diameter dish 2a and diameter dish 2b are linked together, connecting plate 2c and diameter dish 2a are fixed on the installing plate 1, diameter dish 2b is fixed on the connecting plate 2c, can be by the slotted hole on it along connecting plate both sides left and right adjusting, to increase or to reduce diameter dish diameter.
Wire rack 3 is fixed in the slotted hole of installing plate adjustable up and down by screw, compact heap 14.Alignment pin inserts interior location of groove, the guide effect of wire rack bottom on the installing plate.
As shown in Figure 4, briquetting hold down gag 10 comprises and compresses fork 10a, spring lock block 10b, pressing plate 10c, the first cam follower 10d.Compressing fork 10a is installed on the dead axle 7.Spring lock block 10b is fixed on and compresses on fork one support arm, and is adjustable up and down by the slotted hole on it.Pressing plate 10c is fixed on the spring lock block 10b by alignment pin and the screw that passes the arc-shaped slot on it, and pressing plate 10c can rotate around alignment pin during adjusting.As shown in Figure 2, the first cam follower tail end is fixed on another support arm of fork 1a, and the bearing end is embedded in the groove of large fluted disc cam 5.Large fluted disc cam 5 drives the first cam follower 10d, forces to compress fork 10a around dead axle 7 swings, thereby spring lock block 10b and pressing plate 10c are compressed or unclamps knotting spring on the wire rack 3.
Shown in figure (1,3,4), fixture block linkage 9 comprises three fixture block 9a, is provided with the slotted hole 9c that is used for regulating in the fixture block 9a, and fixture block 9a can regulate by the slotted hole 9c on it respectively.Fixture block 9a is separately fixed at the end on the fixed bar 9b, and the other end of fixed bar 9b is separately fixed at and clamps on the fork 9d, and fixed bar 9b is being driven in the slotted hole of installing plate by clamping fork 9d respectively and swinging.Clamping fork 9d can rotate around the clamping fork axle 9e that is fixed on the installing plate 1 respectively.
As shown in Figure 2, the first clamping fork that clamps fork 9d links to each other with clamping swing arm 12 by the bar 11 that flexibly connects of establishing buffer spring in length-adjustable, be contained on the dead axle 7 clamping swing arm 12 with compress fork 10a and be fixed together, rotate around dead axle 7 with compressing fork 10a.Tooth piece and the 3rd on the first clamping fork clamps the tooth piece engagement on the fork.The movable rod 13 and the second clamping fork and the 3rd clamping fork form hinge respectively and are connected.Large fluted disc cam 5 is by the first cam follower 10d, compress fork 10a, force and clamp swing arm 12 around dead axle 7 swings, clamp swing arm 12 and drive the first clamping fork around its clamping fork axle swing by flexible link 11, the first clamping fork is driving its fixed bar and fixture block moves along the installing plate slotted hole, first clamps fork by two tooth pieces, the engagement of tooth piece, driving the 3rd and clamping fork around its clamping fork axle swing, its fixed bar by the 3rd clamping fork band and fixture block moves along the installing plate slotted hole, the 3rd clamps fork passes through the movable rod 13 drives second clamping fork around its clamping fork axle swing, and its fixed bar by the second clamping fork band and fixture block moves along the installing plate slotted hole.Like this shown in figure (1,3,4), three clamp fork 9d and move in the installing plate slotted hole with separately fixed axis simultaneously respectively, clamp 9a is clamped simultaneously or unclamp.
As shown in Figure 2, push rod carriage 8 comprises push rod 8a, slide block 8b, compression spring 8c, axis of guide 8d, the second cam follower 8e.The push rod that passes diameter dish 2a and installing plate internal axle sleeve is fixed on slide block one end, and the slide block other end is installed on the axis of guide 8d, and axis of guide 8d is fixed on the installing plate 1.One compression spring 8c is installed between slide block 8b and the installing plate 1, and slide block 8b and push rod cam 4 one sides have the second cam follower 8e, and the second cam follower 8e is fixed on the slide block 8b.Compression spring 8c forces the second cam follower 8e to contact with cam, and plays cushioning effect when slide block moves.Push rod cam 4 drives the second cam follower 8e, forces slide block 8b being with push rod 8a to move forward and backward in the installing plate axle sleeve along axis of guide 8d.
As shown in Figure 2, push rod cam 4, large fluted disc cam 5 are contained on the same driving shaft 6, can guarantee fixture block 9a and spring lock block 10b, pressing plate 10c like this in fastening spring, and push rod 8a is jack-up correcting spring forward simultaneously also.
As shown in Figure 5, operation principle of the present invention: diameter dish 2 diameter adjustment are arrived appropriate size, manipulator passes the knotting spring and comes, knotting spring first circle 15 packs into diameter dish 2, second circle 16 rests on the wire rack 3, fixture block 9a is under large fluted disc cam 5 drives, by fixture block linkage 9 spring first circle 15 is pressed on the diameter dish 2, meanwhile, spring lock block 10b, pressing plate 10c is under 10 effects of briquetting hold down gag, spring second circle 16 is pressed on the wire rack 3, push rod cam 4 ejects push rod 8a by push rod carriage 8, make push rod head withstand the spring appropriate section, whole like this knotting spring 17 is just clamped firmly, and has guaranteed both ends of the spring bore and spring verticality.
The embodiment of the above is preferred embodiment of the present invention only, is not to limit practical range of the present invention with this, so the equivalence that all shapes according to the present invention, structure and principle are done changes, all should be covered by in protection scope of the present invention.
