Description

The manipulator clamping device is forged in a kind of footpath

Technical field

The utility model relates to the mechanical metallurgy radial forging equipment of metallurgy industry, more particularly, relates to a kind of footpath and forges the manipulator clamping device.

Background technology

The mechanical metallurgy radial forging that is used for metallurgy industry generally is made up of two manipulators and a main frame, and unites forging.Wherein manipulator comprises a clamping device, sees also Fig. 1, shown in Figure 2, and this clamping device 10 comprises four clamps 11, and the center line that is used to clamp workpiece 1 and center on main frame tup and manipulator jaw is rotated.Each clamp 11 comprise jaw 111, tong arm 112 and in establish the balancing pole 113 of dish spring 114 and pull bar 115, jaw 111 is located at tong arm 112 1 ends, balancing pole 113 is located at tong arm 112 1 sides, one end is fixed on the manipulator body 2, the other end is provided with mounting blocks 116, and is connected to a fixed with jaw 111 by two bolts 117.Its operation principle is, when jaw 111 opened, the end that balancing pole 113 is fixed on body 2 was a fulcrum, by spring 114 pushing drawing rods 115 of talking endlessly of inside, the upper end of jaw 111 formed forward thrust, keeps jaw 111 to be close on the tong arm 112; When jaw 111 clamps or clamping when the workpiece 1 of certain taper is arranged, balancing pole 113 reduces at the fixing point of jaw 111 1 ends and the air line distance between the body 2, the dish spring 114 of balancing pole 113 inside is subjected to bigger compression, until when jaw 111 unclamps, dish spring 114 compression stresses discharge, and jaw 111 are readjusted reset.So not only can clamping common planar workpiece, the workpiece 1 that can also clamping has certain taper, and when the workpiece of clamping different size, make workpiece 1 remain consistent with the tup center line by adjusting jaw 111.But in actual use, because being connected between balancing pole 113 and the jaw 111 only relies on two bolts 117, when jaw 111 rotations, this bolt 117 very easily ruptures because of fatigue is stressed, after causing balancing pole 113 1 ends to come off, knock ground and damage and scrap, make that jaw 111 can't the maintenance level when holding workpiece 1, and cause workpiece 1 to depart from tup and center line, so not only easily with workpiece 1 folder curved (seeing shown in Figure 3), and can form the inhomogeneous loss of tup when forging, thereby tong arm 112 is caused bigger stressed, the long-time use can cause tong arm 112 to rupture, not only influence ordinary production, but also brought economic loss.

The specific embodiment

Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.

Further specify the technical solution of the utility model below in conjunction with drawings and Examples.

See also Fig. 4～shown in Figure 6, footpath of the present utility model is forged manipulator clamping device 20 and is comprised four clamps 21, each clamp 21 comprises jaw 211, tong arm 212 and balanced controls 213, jaw 211 is located at an end of tong arm 212, balanced controls 213 comprise and are subjected to mechanical axis 2131, rectangular sleeve 2132 and adjustment component, be subjected to mechanical axis 2131 to be located at tong arm 212 1 ends and pass tong arm 212, and it is symmetrical to be subjected to mechanical axis 2131 to pass the two ends of tong arm 212, also be provided with clamp 2133 in tong arm 212 both sides, clamp 2133 is enclosed within respectively and is subjected to be connected and fixed on the mechanical axis 2131 and with being subjected to mechanical axis 2131, fixed by mechanical axis 2131 and tong arm 212 thereby make, prevent from when tong arm 212 rotates, come off by mechanical axis 2131.Clamp 2133 can be made circlip type, also can fix with being subjected to mechanical axis 2131 direct welding certainly.Rectangular sleeve 2132 is set in respectively on the two ends that are subjected to mechanical axis 2131; and constitute detachable the connection by bolt 2139 with jaw 211; this rectangular sleeve 2132 not only can be used for protecting its inner adjustment component, but also can form a fulcrum on jaw 211.Adjustment component is symmetrically set in and is subjected to mechanical axis 2131 two ends in the rectangular sleeve 2132, each adjustment component includes locating ring 2134, fairlead 2135, helical spring 2136 and adjusts nut 2137, locating ring 2134 is sheathed on and is subjected to mechanical axis 2,131 one ends, with be subjected to mechanical axis 2131 axial restraints, and this locating ring 2134 can rotate freely on the mechanical axis 2131 being subjected to.On locating ring 2134, also be provided with a spring base 2138; Fairlead 2135 is located at the upper end of rectangular sleeve 2132 and is connected with rectangular sleeve 2132 and communicates, and is connected by threaded engagement between fairlead 2135 and the rectangular sleeve 2132.Helical spring 2,136 one ends are located on the spring base 2138, and offset with locating ring 2134, and the other end is located in the fairlead 2135; Adjusting nut 2,137 one ends stretches in the fairlead 2135, and be connected with fairlead 2135 threaded engagement, and helical spring 2136 other ends of adjusting in nut 2,137 one ends and the fairlead 2135 offset, and adjust nut 2137 by rotation and can regulate the tensile force of helical spring 2136.

The operation principle of this clamping device 20 is as follows: when clamp 21 clamps the workpiece that has certain taper, jaw 211 1 ends deflect with the workpiece tapering, thereby driving rectangular sleeve 2132 deflects, helical spring 2136 is stressed and compress, and formation certain angle, thereby drive locating ring 2134 with rotated automatically by force direction, thereby adjust the angle; When clamp 21 unclamped, jaw 211 resetted by the elastic force of helical spring 2136.
