Description

Enamel wire admission machine drum quick-locking device

Technical field

The utility model relates to enamel wire admission machine drum quick-locking device.

Background technology

In the Production of Enamel Wires process, its equipment is divided into unwrapping wire, cures, take-up three big technological processes.Last finished product enamel wire is crimped onto on the enamel wire special plastic drum, and various drums all have certain capacity, just all will change drum after the regular hour.This step is one of main work of direct labor.Present drum is to be through on the axle, and there is screw thread the outer end of axle, and after upgrading bobbin, push drum, fix with thimble shape nut the outer end.The tooth lines of this screw rod all is opposite with the hand of rotation of axle, so just three problems are arranged: first, As time goes on the increase of the line that is carried with bobbin, nut can be gone up tight more more, the squeese pressure that is subjected to that finally may cause drum is excessive and damage, and the second, even drum is not damaged, also can cause drum displacement vertically, the result who causes is that enamel wire is misaligned and become waste product on take-up reel.The 3rd, nut needs the multi-turn rotation in handling process, and the overlong time that spend has increased work load.

The utility model content

It is fragile that the purpose of this utility model solves enamel wire admission machine drum exactly, and easily displacement causes waste product many, and the big problem of loading and unloading work load.

The technical solution adopted in the utility model is: it comprises ring-shaped jacket, ring inner sleeve, circle ring and spring, interior being sleeved in the overcoat, spring housing is contained on the outer wall of inside race, interior cover right part periphery is provided with outwardly directed bulge loop, the extrusion spring right-hand member makes the spring right-hand member spacing, the right part periphery of interior cover is the conical surface, the conical surface is provided with the outwards little through hole of imperial palace of several footpaths, be provided with steel ball in the through hole, the diameter of steel ball is less than the via bottoms diameter, makes steel ball can stretch out via bottoms but can be from the via bottoms landing; Overcoat corresponding end inwall is provided with the ring platform that stretches out to the overcoat centerline direction, the ring platform is connected with the thimble of extruding drum, described circle ring is positioned at overcoat and the bottom is squeezed on the ring platform, and the endoporus of circle ring is and the consistent conical suface of interior cover angle of taper that interior cover conical surface end stretches in the circle ring; Be fixed with the baffle ring that stretches out to the center on the overcoat left end inwall, baffle ring is squeezed on the spring left side.

Adopt technique scheme, when drum is through on the axle, and make axle pass cover central through hole in the above-mentioned latching device, operating personal pulls at interior cover earlier, and the elastic force that interior cover will overcome spring outwards moves, and interior cover is that the inclined-plane cooperates with the circle ring, interior cover outwards moves, steel ball moves the center opposite sense, thereby latching device is penetrated on the axle, when overcoat is squeezed on the drum, unclamp interior cover, interior cover will bounce back under the elastic force of spring, and interior cover moves to circle ring direction, will make the inner conical surface extruding steel ball of circle ring, steel ball is moved to the center, extrusion axis reaches fixing, and the fixing purpose of drum.

For the handled easily personnel exert oneself, described interior cover one end is connected with baffle ring.When overlapping in operating personal pulls at like this, be difficult for skidding.

In sum, the utility model beneficial effect is: because therefore the utility model has improved operating efficiency greatly as long as internally cover pulls at can realize that locking device freely dismantle from axle, thimble can not produce mobile generation deadlock phenomenon, has made things convenient for operation.

The specific embodiment

The utility model enamel wire admission machine drum quick-locking device, as shown in Figure 1, it comprises ring-shaped jacket 6, ring inner sleeve 3, circle ring 10 and spring 7, interior cover 3 is sleeved in the overcoat 6, overlap on 3 outer walls in spring 7 is sleeved on, interior cover 3 right part peripheries are provided with outwardly directed bulge loop 8, extrusion spring 7 right-hand members make the spring right-hand member spacing, the right part periphery of interior cover 3 is the conical surface, the conical surface is provided with the outwards little through hole of imperial palace of several footpaths, be provided with steel ball 9 in the through hole, the diameter of steel ball 9 is less than the via bottoms diameter, makes steel ball 9 can stretch out via bottoms but can be from the via bottoms landing; Overcoat 6 corresponding end inwalls are provided with the ring platform 12 that stretches out to overcoat 6 centerline directions, ring platform 12 is connected with the thimble 11 of extruding drum, described circle ring 10 is positioned at overcoat 6 and the bottom is squeezed on the ring platform 12, the endoporus of circle ring 10 is and the consistent conical suface of interior cover 3 angle of taper that interior cover 3 conical surface ends stretch in the circle ring 10; Be fixed with the baffle ring that stretches out to the center on the overcoat 6 left end inwalls, baffle ring is squeezed on spring 7 left sides.Be easy disassembly, the baffle ring of present embodiment is to constitute like this, as shown in Figure 1, it comprises circle tube 5 and back-up ring B4, and the stack shell diameter of circle tube 5 is greater than the diameter of spring 7, make it can wrap spring 7, the bottom of circle tube 5 is provided with the through hole that passes through for axle, and through-hole diameter makes the projection section to the bottom block spring 7 left parts less than the stack shell diameter, back-up ring B4 extruding circle tube 5 makes circle tube 5 left ends location, thereby reaches spring 7 left ends location.

Interior cover 3 one ends are connected with baffle ring 2.The left end of cover 3 was provided with step surface in present embodiment was achieved in that, made baffle ring 2 directly can insert the left end of interior cover 3, and interior cover 3 left sides also are provided with back-up ring A1, to baffle ring 2 location.
