Description

Automatically structure screws

Technical field

The utility model relates to the manufacturing field of mechanics of communication core component, is specially a kind of structure that screws automatically.

Background technology

Have a large amount of screws to fix on the existing communication cartridge, accomplish more time-consuming, effort by manual work, production efficiency is lower, but also the unequal problem of the power of screwing can occur.

Summary of the invention

To the problems referred to above, the utility model provides a kind of structure that screws automatically, has realized tightening automatically of screw, has reduced labour intensity, has improved production efficiency, and has solved the uneven problem of the power of screwing.

Its technical scheme is such, a kind of structure that screws automatically, and it is characterized in that: it comprises supporting base; First cylinder is fixed on the said supporting base, and support connects said supporting base through line slideway, and said first cylinder piston rod connects said support; Second cylinder and screwdriver bearing are fixed on the said support in the same way, and screwdriver is arranged on the said screwdriver bearing, and the screwdriver whirligig is fixed on the said support; Said screwdriver whirligig connects said screwdriver, and the corresponding said screwdriver of sensor is fixed on the said support, and the stay-supported sensor is fixed on the said supporting base; Said stay-supported sensor connects said support; Said second cylinder piston rod connects the 3rd cylinder piston rod, and said the 3rd cylinder block connects the screwdriver guider, and said screwdriver guider is provided with rotatable armful and grabs; Corresponding screw ingress pipe, said stay-supported sensor and the said sensor connection control system of connecting of said screwdriver guider.

It is further characterized in that: said screwdriver whirligig is a servomotor; Grab the V-shaped inclined-plane of pinching end for said armful.

In the said structure of the utility model, first cylinder is fixed on the said supporting base, and support connects said supporting base through line slideway; First cylinder piston rod connects said support, and second cylinder and screwdriver bearing are fixed on the support in the same way, and screwdriver is arranged on the screwdriver bearing; The screwdriver whirligig is fixed on the support, and the screwdriver whirligig connects screwdriver, and the corresponding said screwdriver of sensor is fixed on the said support; The stay-supported sensor is fixed on the supporting base, and the stay-supported sensor connects support, and second cylinder piston rod connects the 3rd cylinder piston rod; The 3rd cylinder block connects the screwdriver guider, and the screwdriver guider is provided with rotatable armful and grabs, the corresponding screw ingress pipe that connects of screwdriver guider; Stay-supported sensor and sensor connection control system, screw is sent in the screwdriver guider through the screw ingress pipe, and the action of the 3rd cylinder realizes the clamping of band tighten the screws and loosens; Through the relative motion of first cylinder, second cylinder and the rotation of screwdriver, realized tightening automatically of screw, reduced labour intensity; Improved production efficiency, because the control action of sensor has solved the uneven problem of the power of screwing.

The specific embodiment

See Fig. 1, Fig. 2, a kind of structure that screws automatically, it comprises supporting base 1; First cylinder 2 is fixed on the supporting base 1, and support 3 connects supporting base 1, the first cylinder 2 piston rods 5 through line slideway 4 and connects support 3; Second cylinder 6 is fixed on the support 3 with screwdriver bearing 7 in the same way, and screwdriver 8 is arranged on the screwdriver bearing 7, and servomotor 9 is fixed on the support 3; Servomotor 9 connects screwdriver 8, and sensor 10 corresponding screwdrivers 8 are fixed on the support 3, and stay-supported sensor 11 is fixed on the supporting base 1; Stay-supported sensor 11 connects support 3; Second cylinder, 2 piston rods connect the 3rd cylinder 12 piston rods, and the 3rd cylinder 12 cylinder bodies connect screwdriver guider 14, and screwdriver guider 14 is provided with the V-shaped inclined-plane 18-1 of pinching end, 18-2 rotatable armful and grabs 15-1,15-2; The screwdriver guider 14 corresponding screw ingress pipes 16 that connect, stay-supported sensor 11 and sensor 10 connection control system (not drawing among the figure).

In conjunction with Fig. 1, Fig. 2 screw the automatically operation principle of structure of the utility model is described:

Screw falls into the correspondence position of screwdriver guider 14 through screw ingress pipe 16, and second cylinder, 6 piston rods spur the 3rd cylinder 12 cylinder bodies and move upward together with screwdriver guider 14, and screwdriver 8 is descended relatively; Drive screwdriver 8 slow rotation through servomotor 9 simultaneously, the slow rotation while realization screwdriver 8 descends is embraced and is grabbed 15-1,15-2 clamping screw 17; Contact with screw until screwdriver 8 screwdriver bits; After sensor 10 confirmed that screwdriver 8 screwdriver bits and screw 17 grooves coincide, first cylinder 2 began action, and first cylinder, 2 piston rods 5 drive support 3 motions; Screw is contacted with workpiece; Servomotor 9 control screwdrivers 8 rotate, and screw 17 is screwed into several teeth, concrete stroke and be screwed into the tooth number by stay-supported sensor control 11.The 3rd cylinder 12 actions immediately, the 3rd cylinder 12 cylinder bodies move upward together with screwdriver guider 14, because screwdriver is to the pressure of screw; The screw compressing is embraced and is grabbed 15-1,15-2 inclined-plane 18-1,18-2; Embrace and to grab 15-1,15-2 and rotate around axle 13-1,13-2 respectively, embrace and grab 15 and open, unclamp screw 17; First cylinder 2 continues down motion simultaneously; Screwdriver 8 drives the screws rotation, when stay-supported sensor 11 detects that stroke puts in place and moment of torsion is judged to be when reaching the servomotor preset value and accomplishes fluently a screw, does not reach pre-conditioned then system alarm yet if surpass certain hour.
