Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1

Please refer to fig. 1 and fig. 2:

a gripping device for machine manufacturing suitable for use with workpieces of various shapes includes a gripping assembly 10.

In this embodiment: among the prior art, lack the grabbing device that can be applicable to multiple shape work piece, and current grabbing device needs both hands to press from both sides the work piece tightly hard, just portable work piece after keeping the tight dynamics of clamp afterwards, through the subassembly 10 that snatchs that sets up, the usable weight of work piece self of staff makes snatchs more stable.

Further, the method comprises the following steps:

snatch subassembly 10 and include hollow structure's slide rail 11, frame 12, handle 13, two stay ropes 15, two sliders 17, two spring A18 and

splint

19, 11 upper surface mounting of slide rail have frame 12, be provided with handle 13 in the frame 12, two stay ropes 15 are installed to handle 13 lower surface both ends symmetry, slide rail 11 is close to the one end of handle 13 and is seted up the through-hole that uses with the cooperation of stay rope 15, stay rope 15 runs through slide rail 11 and extends to slide rail 11 inboard through this through-hole, and be connected at the inboard slider 17 of slide rail 11 with the setting,

slider

17 and 11 sliding connection of slide rail, slider 17 runs through slide rail 11 and extends to the slide rail 11 outside, the terminal surface that departs from of two sliders 17 all is connected through the inside wall of spring A18 and slide rail 11, splint 19 are installed in the slider 17 outside.

In this embodiment: the staff will wait to snatch the work piece and place in between two splint 19, at first stimulate handle 13, after handle 13 moves towards the direction of keeping away from slide rail 11, stay cord 15 is pulled, the interval between two slider 17 reduces this moment, thereby drive the interval between two splint 19 and reduce, until splint 19 with the work piece centre gripping, the user will snatch subassembly 10 and lift up together with the work piece this moment, because of having established sufficient frictional force between splint 19 and the work piece this moment, the weight of work piece self can drive snatch subassembly 10 and produce decurrent power, the staff holds handle 13 this moment, the work piece dead weight makes handle 13 maintain the trend of moving towards the direction of keeping away from slide rail 11, thereby make splint 19 can the centre gripping work piece all the time.

Further, the method comprises the following steps:

in an optional embodiment, the grasping assembly 10 further includes two limit blocks 14, the limit blocks 14 are installed on two sides of the handle 13, and a sliding groove matched with the limit blocks 14 is formed on the inner side of the frame 12.

In this embodiment: through the arrangement of the limiting block 14 and the matched handle 13, the handle 13 can be always kept in the frame 12 to move along the wall thickness of the frame 12, and the handle 13 is prevented from being separated from the frame 12.

Further, the method comprises the following steps:

in an alternative embodiment, the grabbing assembly 10 further comprises two sheaves 16, the sheaves 16 are mounted inside the sliding rail 11 through a rotating shaft, and the sheaves 16 and the pulling rope 15 are used in cooperation.

In this embodiment: through the sheave 16 that sets up, cooperation stay cord 15 uses, avoids stay cord 15 direct contact to slide rail 11 to avoid stay cord 15 and slide rail 11 friction to produce the loss, with the life who improves stay cord 15.

As shown in fig. 1, 3 and 4:

this machine-building is with being applicable to multiple shape work piece grabbing device still includes that a plurality of groups install adaptation subassembly 20 on splint 19, adaptation subassembly 20 includes movable rod 21, spring B22 and fixed block 23, movable rod 21 runs through splint 19, movable rod 21 and splint 19 sliding connection, the cover is equipped with spring B22 in the movable rod 21 outside, spring B22 is located two splint 19's the terminal surface department that leaves mutually, fixed block 23 is still installed in the movable rod 21 outside, spring B22's one end and splint 19 are connected, the one end that splint 19 was kept away from to spring B22 is connected with fixed block 23.

In this embodiment: when the distance between the clamping plates 19 is reduced, the movable rods 21 firstly contact the surfaces of the workpieces, and because the adapting assemblies 20 have multiple groups, the positions of contact points of each movable rod 21 and the workpieces are different, the movable rods 21 move to a certain extent, the springs B22 are stretched, and the moving amount of the movable rods 21 is increased along with the reduction of the distance between the clamping plates 19, so that the pressure between the movable rods 21 and the workpieces is increased by the aid of the tensile force of the springs B22, and the pressure is converted into friction force, namely, the adapting to different types of workpieces is realized, and the adapting effect to special-shaped workpieces is also excellent.

Further, the method comprises the following steps:

in an alternative embodiment, the adapting assembly 20 further comprises a non-slip pad 24, the non-slip pad 24 being mounted at an end of the movable bar 21 remote from the fixed block 23.

In this embodiment: because of the non-slip mat 24 is installed at the one end of movable rod 21 far away from fixed block 23 for non-slip mat 24 and the surperficial direct contact of work piece, thereby can increase the frictional force between with the work piece, make snatch more stable.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the utility model. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
