[0035] In view of this, the core of the present invention is to provide a lifting and clamping device, which can effectively reduce the space occupied and improve the compactness of the structure.

[0036] The following will combine the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Please refer to Figures 1 to 7 .

[0037] Please refer to Figures 1 to 3 The lifting and clamping device disclosed in the embodiment of the utility model includes a driving mechanism 100, a transmission mechanism 200, a clamping mechanism 300 and a lifting mechanism 400.

[0038] Among them, there is one driving mechanism 100, which is connected to the transmission mechanism 200. The driving mechanism 100 can transmit power to the transmission mechanism 200. The lifting mechanism 400 and the clamping mechanism 300 are respectively connected to the transmission mechanism 200. The transmission mechanism 200 can transmit power to the lifting mechanism 400 and the clamping mechanism 300 respectively, so that the lifting mechanism 400 can lift and lower the clamping parts to be lifted and lowered, and the clamping mechanism 300 can clamp the clamping parts to be lifted and lowered.

[0039] When the clamping piece to be lifted or lowered is to be lifted or lowered and clamped, the driving mechanism 100 is started, and the driving mechanism 100 transmits power to the transmission mechanism 200, and the transmission mechanism 200 transmits power to the lifting mechanism 400 and the clamping mechanism 300, so that the lifting mechanism 400 can lift the clamping piece to be lifted or lowered, and the clamping mechanism 300 can clamp the clamping piece to be lifted or lowered.

[0040] Compared with the prior art, the lifting and clamping device disclosed in the embodiment of the utility model is only provided with a driving mechanism 100, through which power can be transmitted to the transmission mechanism 200, and then transmitted to the clamping mechanism 300 and the lifting mechanism 400. Therefore, the above-mentioned lifting and clamping device can effectively reduce the space occupied and improve the compactness of the structure.

[0041] The embodiment of the present utility model does not specifically limit the transmission mechanism 200. As long as the structure meets the use requirements of the present utility model, it is within the protection scope of the present utility model.

[0042] As one embodiment, the transmission mechanism 200 disclosed in the embodiment of the utility model includes an input gear 201, an output gear 202 and a worm gear assembly.

[0043] Among them, the input gear 201 is connected to the driving mechanism 100, the output gear 202 is connected to the lifting mechanism 400, and the worm gear assembly is connected to the clamping mechanism 300. The input gear 201 can transmit power to the output gear 202 and the worm gear assembly to drive the lifting mechanism 400 and the clamping mechanism 300 to move.

[0044] In a specific embodiment of the utility model, the input gear 201 includes two meshing parts, one of which meshes with the driving gear 101, and the other meshes with the output gear 202. A center hole is provided on the input gear 201, and a worm 203 of the worm gear assembly is installed in the center hole. The worm wheel 204 in the worm gear assembly is installed on the clamping mechanism 300. Through the interaction between the worm wheel 204 and the worm 203, the clamping mechanism 300 clamps the clamped part.

[0045] As a further example, please refer to Figure 2 , Figure 4 and Figure 5 The transmission mechanism 200 disclosed in the embodiment of the utility model further includes a transition gear 205, which is disposed between the input gear 201 and the output gear 202, and the transition gear 205 can mesh with the input gear 201 and the output gear 202 respectively.

[0046] Among them, a mounting hole is set on the transition gear 205, the worm 203 in the worm gear assembly is installed in the mounting hole, and the worm wheel 204 in the worm gear assembly is set on the clamping mechanism 300. Such a setting can facilitate the overall arrangement of various components of the lifting and clamping mechanism 300.

[0047] When the driving mechanism 100 is started, the driving mechanism 100 drives the input gear 201 to rotate, the input gear 201 drives the transition gear 205 to rotate, and the transition gear 205 drives the output gear 202 to rotate. Since the output gear 202 is connected to the lifting mechanism 400, the output gear 202 can drive the lifting mechanism 400 to perform a lifting action, thereby realizing the lifting and lowering of the clamping part to be lifted and lowered.

[0048] When the transition gear 205 rotates, the worm 203 rotates along with the transition gear 205 , and the worm wheel 204 matched with the worm 203 rotates, thereby driving the clamping mechanism 300 to operate, so as to clamp the clamping member to be lifted.

[0049] As a specific example, please refer to Figure 6 and Figure 7 The driving mechanism 100 disclosed in the embodiment of the utility model includes a driving mechanism body, a driving shaft and a driving gear 101, wherein the driving shaft is installed on the driving mechanism body, and the driving gear 101 is installed on the driving shaft. By starting the driving mechanism 100, the driving shaft is driven to rotate, and then the driving gear 101 is driven to rotate.

[0050] The input gear 201 includes a first meshing portion 2011 and a second meshing portion 2012 , and the transition gear 205 includes a third meshing portion 2051 and a fourth meshing portion 2052 .

[0051] The first meshing portion 2011 meshes with the driving gear 101 , the second meshing portion 2012 meshes with the third meshing portion 2051 , and the fourth meshing portion 2052 meshes with the output gear 202 .

[0052] The diameters of the first meshing portion 2011 and the second meshing portion 2012 disclosed in the embodiment of the utility model may be the same or different, and the diameters of the third meshing portion 2051 and the fourth meshing portion 2052 may be the same or different.

[0053] As a preferred embodiment, the diameters of the first meshing portion 2011 and the second meshing portion 2012 disclosed in the embodiment of the utility model are different. In this configuration, the input gear 201 has a step structure.

[0054] The diameters of the third meshing portion 2051 and the fourth meshing portion 2052 are different. With this arrangement, the transition gear 205 also has a step structure. The arrangement of the above structure can facilitate meshing between gears and prevent mutual interference.

[0055] In order to enable slipping to be achieved when the stall torque of the driving mechanism 100 is large, the lifting and clamping mechanism 300 disclosed in the embodiment of the utility model also includes a clutch 206, wherein the clutch 206 is arranged between the transition gear 205 and the worm 203 in the worm gear assembly (for example, the driving mechanism 100 outputs 5kg of power, and slipping is achieved when the clutch 206 reaches 1kg).

[0056] The embodiment of the present invention does not limit the specific structure of the clutch 206. The clutch 206 can be a damping clutch, a compression spring clutch, or a clutch of other structures. As long as the clutch structure meets the use requirements of the present invention, it is within the protection scope of the present invention.

[0057] The embodiment of the present utility model does not limit the specific structure of the clamping mechanism 300. As long as the structure meets the use requirements of the present utility model, it is within the protection scope of the present utility model.

[0058] As one embodiment, the clamping mechanism 300 disclosed in the embodiment of the utility model includes a first screw rod 301, a first nut 302 and a second nut 303, and the first nut 302 and the second nut 303 are both threadedly connected to the first screw rod 301;

[0059] The worm wheel 204 in the worm gear assembly is disposed on the first screw rod 301 , and the thread directions of the first nut 302 and the second nut 303 are opposite, so that the first nut 302 and the second nut 303 can be moved closer to or farther from each other on the first screw rod 301 .

[0060] When the worm 203 rotates, the worm wheel 204 also rotates, and the worm wheel 204 drives the first screw rod 301 to rotate. Since the first nut 302 and the second nut 303 are both threadedly connected to the first screw rod 301, when the first screw rod 301 rotates forward, the first nut 302 and the second nut 303 approach each other to clamp the lifting clamp. When the first screw rod 301 rotates reversely, the first nut 302 and the second nut 303 move away from each other to loosen the lifting clamp.

[0061] The lifting clamping member disclosed in the embodiment of the utility model further includes a first clamping member 304 and a second clamping member 305. Figure 3 The first clamping member 304 is disposed on the first nut 302 , and the second clamping member 305 is disposed on the second nut 303 .

[0062] When the first nut 302 and the second nut 303 move toward or away from each other along the first screw rod 301 , the first clamping member 304 and the second clamping member 305 also move accordingly.

[0063] It should be noted that the lifting and clamping device disclosed in the embodiment of the utility model is installed on the housing 500 , wherein both ends of the first screw rod 301 are respectively connected to the housing 500 , and the first nut 302 and the second nut 303 are both fixed on the housing 500 .

[0064] The embodiment of the utility model does not limit the specific position of the worm wheel 204 in the worm gear assembly on the first screw 301, wherein the worm wheel 204 in the worm gear assembly can be set between the first nut 302 and the second nut 303, can be set on the outside of the first nut 302, and of course can also be set on the outside of the second nut 303. Those skilled in the art can make arrangements according to the actual layout structure.

[0065] When it is necessary to explain, the outside of the first nut 302 refers to the space between the first nut 302 and the housing 500 , and the outside of the second nut 303 refers to the space between the second nut 303 and the housing 500 .

[0066] The embodiment of the present utility model does not limit the specific structure of the lifting mechanism 400. As long as the structure meets the use requirements of the present utility model, it is within the protection scope of the present utility model.

[0068] When the output gear 202 rotates, the second screw rod 401 is driven to rotate. Since the second screw rod 401 is threadedly connected to the lifting block 402 , when the second screw rod 401 rotates, the lifting block 402 can move up or down on the second screw rod 401 .

[0069] In order to guide the lifting block 402 , the lifting mechanism 400 disclosed in the embodiment of the utility model further includes a guide rod 403 , wherein the guide rod 403 is slidably connected to the lifting block 402 .

[0070] There is at least one guide rod 403 . Preferably, there are two guide rods 403 , which are respectively disposed on both sides of the second screw rod 402 .

[0071] It should be noted that the driving mechanism 100 disclosed in the embodiment of the utility model can be a motor, an electric machine, or other driving mechanisms, and the embodiment of the utility model does not specifically limit this.

[0072] Finally, it should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprises" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
