The feed collet has high automatic degree but no potential safety hazard.

Description

A kind of feed collet

Technical field

The present invention's step and a kind of feed collet, the automatic feed collet of especially a kind of mechanical type.

Background technology

Feed collet is factory's a kind of clamping device commonly used.The factory owner will come the block object of clamping with feed collet, promotes the transfer of laggard line position then by driving.Existing feed collet as shown in Figure 1, it is hinged by being " X " shape after two tongs intersections, connect steel cable on two tongs, steel cable hangs on the hook of driving during use, then by two operating personnel respectively from catching the handle that is fixed on the tong, tong is opened, in object entered opening, operating personnel decontroled handle, and the driving hook rises, at this moment tong will be clamped object, can realize that object shifts moving down of driving.The advantage of above-mentioned tong is simple in structure, and cost is low, and is easy to use.But its shortcoming is owing to need many people manually to operate, so production automation degree is low, cost of labor is high, owing to need artificial auxiliary operation, brings bigger hidden danger for the safety in production of factory simultaneously.

Summary of the invention

Purpose of the present invention just provides a kind of safety, feed collet that automaticity is high.

The technical solution used in the present invention is: a kind of feed collet, it is characterized in that it comprises clamping device, tong controlling organization and shackle, clamping device comprises four tongs, four connecting plates and first rotating shaft, second rotating shaft, the 3rd rotating shaft and the 4th rotating shaft, the relative two ends that intersect and be rotatably connected in the 4th rotating shaft in the crosspoint of per two tongs, the tong that the 4th rotating shaft end positions is identical is connected in the two ends of second rotating shaft and the 3rd rotating shaft respectively with the connecting plate co-rotation, two connecting plates of rotating shaft homonymy are rotatably connected in the two ends of first rotating shaft; Described tong controlling organization comprises guide rod, two hooks, upper conical cover and inferior pyramidal covers, two hook symmetries are rotatably connected in the below of first rotating shaft, in the 4th rotating shaft, be provided with through hole, be connected with mounting pipe in the through hole, upper conical cover is fixed on the upper end of mounting pipe, the inferior pyramidal cover is sleeved on the mounting pipe, and also activity is connected with guide rod below first rotating shaft, and the lower end of guide rod is positioned at mounting pipe; In first rotating shaft, rotate and be connected with shackle.

Adopt such scheme, when need gripping material, shackle is hung on the main hook of driving, main hook descends, feed collet is under main hook and the gravity effect of self, tong and connecting plate open, the feed collet height descends, because the guide effect of guide rod is arranged, guarantee to descend and do not depart from, when dropping to certain altitude, two hooks at first touch upper conical cover, continue to glide along upper conical cover, cross upper conical cover, at this moment the main hook of driving a vehicle rises, two little hooks of feed collet are along with rising, and two little hooks at first hook upper conical cover, make upper conical cover along with little hook rises, upper conical cover will spur first rotating shaft and rise, two tongs are opened, the clipped object material place of walking, material places in two tongs, the main hook of driving descends once more, rise after crossing inferior pyramidal cover, two little hooks hook the inferior pyramidal cover and rise together again, stop when taper sheath runs into upper conical cover instantly, two little hooks slip over along inferior pyramidal cover surface, the inferior pyramidal cover, along with the continuation of driving main hook is risen, two tongs will be clamped material, and the driving walking can be delivered to the appointed place, realize repeating the open action in front when decontroling material from transporting gripping.

For increasing the clamping area of tong, two the tong inboards identical in the position are fixed with angle steel.So both can play the effect that increases the clamping area, also can fix two tongs of a side.

For making the feed collet can the different material of gripping, described upper conical cover be by thread connection on mounting pipe.Can reach and regulate the open openings of sizes of tong by regulating the position of upper conical cover like this.

In sum, effect of the present invention is: since need not during gripping material of the present invention artificial auxiliary, so automaticity height of the present invention, no potential safety hazard.
