It should be noted that: the relative arrangement of the components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present application unless it is specifically stated otherwise.

The following description of at least one exemplary embodiment is merely exemplary in nature and is in no way intended to limit the application, its application, or uses.

Techniques, methods, and apparatus known to one of ordinary skill in the relevant art may not be discussed in detail, but are intended to be part of the specification where appropriate.

In all examples shown and discussed herein, any specific values should be construed as merely illustrative, and not a limitation. Thus, other examples of exemplary embodiments may have different values.

Example 1:

as shown in fig. 1 to 4, the present embodiment provides a clasping device, including: the two clamping plates 100 and the sliding rail 200 are oppositely arranged, and the clamping plates 100 have the freedom of movement for carrying out opposite or reverse translation along the sliding rail 200; further comprises: pallet 300, telescoping pawl 400, and pawl driving mechanism 500; the lower ends of the two clamping plates 100 are respectively provided with a supporting plate 300; one end of the supporting plate 300, which is close to the clamping plane S of the clamping plate 100, is flush with the clamping plane S; the telescopic claws 400 and the claw driving mechanism 500 are respectively arranged on the supporting plate 300; the jaw driving mechanism 500 drives the telescopic jaw 400 to extend or retract toward the gripped object; when the telescopic claw 400 is retracted, the end of the telescopic claw 400 is flush with the clamping plane S of the clamping plate.

When the clamping plate 100 is used for clamping a cargo, the clamping jaw driving mechanism 500 drives the clamping jaw 400 to act, stretches into the bottom of the clamped cargo, forms a embracing operation with the clamping jaw, can firmly clamp the cargo between the two clamping plates, and avoids unexpected sliding of the cargo due to overweight or other reasons. When the goods need to be put down, the jaw driving mechanism 500 drives the jaw 400 to act, the jaw is retracted from the bottom of the goods to the position that the end is flush with the clamping plane S of the clamping plates, the clamping plates 100 do reverse translation along the sliding rail 200 under the action of clamping driving equipment of the clamping machine, and the goods automatically slide down from the middle of the two clamping plates.

It should be noted that, in the above embodiment, the structure of the jaw driving mechanism may be implemented according to the prior art, so the related structural details thereof are not further illustrated and described herein.

Because the material of tobacco trade holds in the tray generally, receives the influence of tray degree of depth, and the position that the goods was pressed from both sides by splint and the goods bottom position have the deviation in the size, the jack catch of above-mentioned structure can't stretch into the goods bottom when splint press from both sides and get the goods generally, and then can't reach the result of use of firm cohesion. As an example, as shown in fig. 1, the pallet 300 is a floating pallet; the floating pallet has a degree of freedom of movement to move up and down relative to the clamping plate 100. After the floating structure is adopted, the floating type supporting plate can automatically move upwards to compensate the size deviation when the floating type supporting plate and the outer edge upper end face of the tray are touched, when the goods are clamped and lifted, the floating type supporting plate automatically moves downwards to reset, and the clamping jaw can accurately extend into the bottom of the goods at the moment, so that the use effect of encircling the goods with the clamping plate is achieved.

In one of the usage modes, as shown in fig. 1, 2 and 4, the floating pallet includes: a bottom plate 310, a guide bar 320, a guide holder 330 and a return spring 340; the guide seat 330 is fixedly arranged on the back side of the clamping plate 100 relative to the clamping plane S; the guide bar 320 has a degree of freedom of movement to slide up and down within the guide holder 330; the guide rod 320 is provided with a limiting part 321 for limiting the sliding of the upper part and/or the lower part; the return spring 340 is fixedly connected between the lower end surface of the clamping plate 100 and the upper end surface of the bottom plate 310 in a compressed state, and the end portion is fixedly connected with the contact portion; the return spring 340 has a deformation stroke that is further compressed.

Preferably, the limiting portion 321 is implemented by a nut screwed on the guide bar 320, and is disposed at an upper end of the guide bar 320. In order to prevent the nuts from loosening and shifting, the use effect of locking the limiting part can be achieved by adopting a structure mode that two nuts in the diagram are interlocked.

As an embodiment, as shown in fig. 1 and 4, the floating pallet is provided with a groove 350 with a shape matching the telescopic jaw 400; the telescopic claw 400 is arranged in the groove.

As an embodiment, the jaw driving mechanism 500 is one of a cylinder, a hydraulic cylinder, and an electric push rod.

As an example, as shown in fig. 1, the floating pallet is provided with a transition slope X1 toward one end of the object to be gripped. Preferably, the included angle of the transition inclined plane relative to the horizontal plane is 45 degrees. The improved floating supporting plate has better touch flexibility when offset with the upper edge of the tray.

As an embodiment, as shown in fig. 1, one end of the telescopic claw facing the object to be clamped is provided with a grabbing shovel inclined plane X2; the inclined direction of the grabbing shovel inclined plane X2 is opposite to that of the transition inclined plane X1. Preferably, the included angle of the grabbing shovel inclined plane X2 relative to the horizontal plane is 45 degrees. The improved telescopic claw can be more beneficial to quickly extending into the bottom of goods, so that a more stable embracing operation effect is formed.
