The specific embodiment

See also Fig. 1 to shown in Figure 4, find out that by knowing among the figure gripping body of the present utility model, this gripping body are provided with substrate 1, plural clamping limb 2, flexible member 3, catch bar 5 and driver 6, wherein:

This substrate 1 surface is concaved with plural number first side by side against groove 11, be provided with bearing 12 in substrate 1 two sides, be fixed with a jack-post 13 between two bearings 12, be provided with stopper slot 14 away from first against groove 11 places at substrate 1, and substrate 1 is connected with connecting plate 7 away from a side of two bearings 12, connecting plate 7 is equipped with two perforation 71, is positioned at two perforation 71 side places away from substrate 1 at connecting plate 7 and respectively is connected with driver 6.

Each clamping limb 2 is arranged side by side in substrate 1 away from driver 6 one side surfaces, and each clamping limb 2 has articulated section 21, each articulated section 21 is equipped with through hole 211, when each clamping limb 2 is arranged side by side, each through hole 211 is interconnected, being used for the jack-post 13 of substrate 1 sequentially penetrates each through hole 211 and allows clamping limb 2 produce and articulate turns, and each clamping limb 2 is extended with respectively pushing part 22 and clamping part 23 in its articulated section 21 2 ends, each pushing part 22 is fixed with fixture 8, and each pushing part 22 is formed with spacing with substrate 1, be provided with flexible member 3 in order to do allowing between each pushing part 22 and the substrate 1, and each flexible member 3 one end is positioned at the stopper slot 14 of substrate 1, its end is fixed in connecting plate 7 simultaneously, each flexible member 3 opposite side is fixed in the fixture 8 of each pushing part 22, and clamping part 23 is concaved with second against groove 231 away from the end surface of articulated section 21, and second against groove 231 be right against respectively substrate 1 first against groove 11, make first to be formed with grasping part 4 against groove 11 and second against groove 231.

This catch bar 5 has pushing part 51, and catch bar 5 is positioned at pushing part 51 2 sides and is extended with connecting portion 52, the pushing part 51 of catch bar 5 is positioned at the pushing part 22 of each clamping limb 2 away from the opposite side surface of substrate 1, and two connecting portions, 52 ends pass through and are connected in two drivers, 6, two drivers 6 after two of connecting plate 7 perforation 71 again and are used for promoting catch bar 5 displacements.

See also Fig. 3 to shown in Figure 8, find out action schematic diagram of the present utility model by knowing among the figure, as shown in Figure 5, when startup is used for driving two driver 6 of catch bar 5 displacements, the connecting portion 52 that two drivers 6 can spur catch bar 5 simultaneously produces displacement, allow two connecting portions 52 drive simultaneously the pushing part 51 of catch bar 5, pushing part 51 can promote the pushing part 22 of each clamping limb 2, make the pushing part 22 of each clamping limb 2 be subjected to pushing part 51 promotions of catch bar 5 rear towards substrate 1 displacement, and lasting extruding flexible member 3, produce the elastic reset ability after allowing each flexible member 3 by each self-corresponding pushing part 22 extruding, and each clamping limb 2 second against groove 231 and substrate 1 first against groove 11 mutually away from, be the SBR of gripping workpiece 9 this moment, as shown in Figures 7 and 8, when the utility model during in gripping workpiece 9, each driver 6 can drive catch bar 5 displacements, allow the pushing part 51 of catch bar 5 be moved to away from substrate 1 place, simultaneously each flexible member 3 rely on aforesaid elastic reset ability with the pushing part 22 of each clamping limb 2 towards promoting away from substrate 1 direction, be that the pushing part 22 of each clamping limb 2 is according to after its articulated section 21 turns, allow second against groove 231 can near substrate 1 first against groove 11, can be formed clamp position against groove 231 and first against groove 11 urgent compressing by second in order to do the workpiece 9 of making way in the grasping part 4; When workpiece 9 wishs break away from clamp position, two drivers 6 drive the pushing part 51 of catch bar 5 towards close substrate 1 direction displacement, this pushing part 51 can once promote the pushing part 22 of each clamping limb 2 towards substrate 1 displacement simultaneously, in order to do allow second against groove 231 towards away from first against groove 11 displacements, allow workpiece 9 can break away from second against groove 231 and the first clamp position against groove 11, namely finish the blowing action of workpiece 9.

So, the utility model can solve existing problem and disappearance, its key technology is, each clamping limb 2 is all arranged in pairs or groups separately and is had elastic component 3, and utilize a catch bar 5 to promote simultaneously plural clamping limb 2 turn displacements, rely on this kind mechanism to get final product gripping plural number workpiece 9 and process, and utilize driver 6 start catch bars 5 simultaneously workpiece 9 is carried out the blowing action, promote the efficient of transfer workpiece 9.

More than explanation is just illustrative for the utility model; and nonrestrictive, those of ordinary skills understand, in the situation that does not break away from the spirit and scope that claim limits; can make many modifications, variation or equivalence, but all will fall within the protection domain of the present utility model.
