Abstract

A hand-held electric core-pulling rivetter features that a leading scrwe-nut pair is used to convert the rotation of motor to straight-line movement for pulling rivet. Said nut is a jaw nut consisting of nut lobes, elastic connecting plate, pull ring, slide block in slide way, and control handle.

Description

Hand electric core extraction pneumatic riveter

Technical field

The invention belongs to electric tool class, particularly hand electric core extraction pneumatic riveter.

Background technology

Used in the market hand electric core extraction pneumatic riveter complex structure, axial dimension is big, and the cost height carries, inconvenient operation.

Summary of the invention

The objective of the invention is provides a kind of hand electric core extraction pneumatic riveter of novelty in order to overcome the deficiency of above hand electric core extraction pneumatic riveter instrument, can use self-plugging rivet that sheet material is riveted easily and quickly, it is simple in structure, and is easy to use and reliable, and cost is low, volume is little, and is in light weight.

The technical solution adopted for the present invention to solve the technical problems is: the leading screw during the driven by motor feed screw nut is paid rotates, nut moves linearly, this nut is the claw type structure, under the cooperation of clasp, can hold leading screw tightly or loosen leading screw, realize spurring and pull out cover, pull rivet core and the function that dial sleeve resets after the fracture of nail core.

The present invention compared with prior art, its advantage is: simple in structure, be convenient to the operation, easy to use.

Description of drawings

The present invention is further described below in conjunction with drawings and Examples.

Fig. 1 is first embodiment cutaway view of hand electric core extraction pneumatic riveter.

Fig. 2 is hand electric core extraction pneumatic riveter claw type nut front view, cutaway view.

Fig. 3 is second embodiment partial sectional view of hand electric core extraction pneumatic riveter.

Among Fig. 1, Fig. 2, Fig. 3: 1. rifle head screw, 2. cushion pad, 3. jaw, 4. core is split, and 5. pulls out cover, 6. rifle head, 7. casing, 8. pull bar, 9. clasp, 10. pawl nut, 11. leading screws, 12. motors, 13. handles, 14. the rifle tongue, 15. push buttons, 16. return springs, 17. core springs, 18. pinions, 19. gear wheels.

In first implementation column of Fig. 1, the overhanging end of motor (12) axle is made leading screw (11), pawl nut (10) is by draw ring (10-3), elasticity is (10-2) in flakes, nut lobe (10-1) and slide block (10-4), control handle (10-5) constitutes, slide block (10-4) can slide on the slideway of casing (7), the rotation of restriction pawl nut (10), at initial (outage) state, when pawl nut (10) is reset spring (16) when drawing in the high order end position by pull bar (8), clasp (9) is buckled on the nut lobe (10-1), nut lobe (10-1) is held leading screw tightly, simultaneously, return spring (16) will pull out cover (5) and withstand on the cushion pad (2), pull out cover (5) and pull bar (8) is tightened with screw thread, be convenient to the dismounting assembling, core spring (17) is split (4) by core jaw (3) is withstood on the rifle head screw (1), because rifle head screw (1), jaw (3), the end face that core is split (4) is the conical surface, jaw (3) is made of two lobes or three lobes, therefore jaw (3) is pushed up and is opened, be convenient to rivet and put into, by changing the rivet that rifle head screw (1) can use different model.

During use, the operator hands this riveting gun handle (13), rivet is followed closely core to be inserted in the rifle head screw (1), the rivet front end inserts in the hole of sheet material to be riveted, pull rifle tongue (14) and depress push button (15), motor (12) energising, the leading screw rotation, the pawl nut of holding tightly (10) moves to right, drive pull bar (8), pulling out cover (5) moves right, jaw (3) is under the thrust of core spring (17), relative motion is left arranged, because jaw (3) outer surface is conical, under the effect of pulling out cover (5) left end face, the rivet core is blocked and draws to the right, rupture up to the rivet core, riveted joint finishes, at this moment, pawl nut (10) arrives right-hand member boss (7-1) position of casing (7), pawl nut (10) continues walking to the right, boss (7-1) pushes up clasp (9) from nut lobe (10-1) position, nut lobe (10-1) outwards launches under the elastic reaction of (10-2) in flakes in elasticity, and nut lobe (10-1) breaks away from leading screw (11), and control handle (10-5) is depressed the other end of rifle tongue (14) simultaneously, push button (15) is resetted, the stall of motor dead electricity, pawl nut (10) promote clasp (9) to left movement under the effect of return spring (16), up to the adapter ring platform of casing clasp (9) is blocked and shift onto nut lobe (10-1) position, nut lobe (10-1) is held leading screw tightly, prepare startup next time, simultaneously, return spring (16) also will pull out cover (5) and push cushion pad (2) to, jaw (3) is withstood on the rifle head screw (1), jaw (3) opens, and can put into one piece of new rivet, repeats riveting work.

In second embodiment of Fig. 3, motor can pass through pinion (18) and gear wheel (19) engagement is given leading screw with transmission of power.All the other structures are identical with first embodiment.

Claims

1. a hand electric core extraction pneumatic riveter comprises rifle head screw, cushion pad, jaw, core is split, and pulls out cover, the rifle head, casing, pull bar, clasp, pawl nut, leading screw, motor, handle, rifle tongue, push button, return spring, core spring, it is characterized in that: the overhanging end of motor shaft is made the leading screw of feed screw nut in paying, and its nut is the pawl nut, the opening of pawl nut, close by clasp and control, return spring is enclosed within and pulls out on cover and the pull bar, and two ends withstand on casing respectively and pull out and put, and pulls out to overlap to withstand on the cushion pad and with jaw to cooperate, core spring one end withstands on the pull bar, the other end withstands on core and splits, and core is split jaw is withstood on the rifle head screw, and rifle head screw is connected on the rifle head.
