The described base of tool radially equal angles is offered three chutes; Offer three gradients on the internal ring wall of described driving ring and become big short slot gradually.

After adopting such scheme, because the utility model drives driving ring by cylinder and rotates, the driving ring rotational synchronization drives the riveted cutter action of slipping in the base of tool, the riveted joint piston rod, as long as control three groove size precision of driving ring well, just can guarantee the riveted precision of piston rod, and accessory size can be measured very easily to have simple in structure, riveted positioning stablity degree height, long service life, advantage easy to process.

Below in conjunction with the drawings and specific embodiments the utility model is further described.

Description of drawings

Fig. 1 is the utility model axonometric drawing;

Fig. 2 is not riveted of the present utility model state diagram;

Fig. 3 is riveted state diagram of the present utility model;

Fig. 4 is the riveted state diagram that the utility model quick chuck presses down.

The specific embodiment

As Fig. 1, shown in Figure 4, the utility model is a kind of piston rod riveted equipment, and it mainly is made up of board 1, quick chuck 2, cylinder 3, cylinder push rod 4, driving ring 5, the base of tool 6, riveted cutter 7, retainer spring 8, fastening screw 9, limited block 91.

Described quick chuck 2 is installed on the column 11 of board 1.

The described base of tool 6 is installed on board 1 table top 12, be provided with the workpiece fixing seat 61 that is used for place work piece at the center of the base of tool 6, offer an annular groove 62 around this workpiece fixing seat 61, with workpiece fixing seat 61 be the center radially equal angles offer 63, three chutes 63 of three chutes two ends be communicated with workpiece fixing seat 61 and annular groove 62 respectively.

Described driving ring 5 activities are nested with in the annular groove 62 on the base of tool 6, extend outward a boss 51 on the external annulus of driving ring 5, offer three gradients and become big short slot 52 gradually on the internal ring wall of driving ring 5.

Described cylinder 3 is fixed on the table top 12 of board 1, and the piston rod of cylinder 3 is connected with cylinder push rod 4, and boss on cylinder push rod 4 and the driving ring 5 51 is hinged and can drive driving ring 5 and rotate along the annular groove on the base of tool 6 62.

Described limited block 91 is installed on board 1 table top 12 and is positioned on the motion track of cylinder push rod 4, is used to limit the displacement of cylinder push rod 4.

Described riveted cutter 6 has three, slips respectively in three chutes 63 of the base of tool 6, and workpiece fixing seat 61 is stretched in its inner, and its outer end is semicircle, can lean and can slip into driving ring 5 internal ring walls in the short slot 52 on the driving ring internal ring wall; Described fastening screw 9 is plugged on chute 63 bottoms of the base of tool 6, and the two ends of retainer spring 8 are articulated in respectively on riveted cutter 7 and the fastening screw 9.

Operation principle of the present utility model:

When 1, equipment is static: as shown in Figure 1 and Figure 2, quick chuck 2 is in last halt, cylinder push rod 4 is in starting point, the 7 semicircle outer end beginnings of riveted cutter are stuck in the short slot 52 of driving ring 5, piston rod 10 is riveted not as yet, retainer spring 8 involutions do not stretch, and fastening screw 9, fixing spring 8 and riveted cutter 6 are in the initial place.

2, during the equipment run action: as shown in Figure 3, Figure 4, quick chuck 2 presses to the summit of piston rod 10 until maintaining static, cylinder push rod 4 pushes up to halt, riveted cutter 6 because of cylinder push-rod 4 be pushed into the summit drive driving ring 5 rotate that beginning riveted cutter 6 leaves short slot 52 and then promote three riveted cutters 6 to piston rod 10 must riveted joints place, retainer spring stretches for 8 this moments, and fastening screw 9 stretches because of an end retainer spring 8 front ends retainer spring this moment 8 and fastening screw 9 produces the stress that stretches

3, during device reset: as shown in Figure 1 and Figure 2, quick chuck 2 retracts halt, cylinder push rod 4 is backed to square one, after resetting, riveted cutter 6 semicircle outer ends block back in the short slot 52 of driving ring 5, piston rod 10 riveteds are finished, retainer spring 8 involution unstretched states, fastening screw 9 produces short slot 52 places that the reaction pulling force retracts retainer spring 8 and riveted cutter 6 initial driving ring 5.

Emphasis of the present utility model just is: with the action of driving ring driven in synchronism riveted cutter.

The above, it only is the utility model preferred embodiment, the quantity of riveted cutter can be adjusted according to needs, so can not limit the scope that the utility model is implemented with this, the i.e. equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
