In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.
[0042] This embodiment provides a fixture set, which includes a packaging box 200 and a fixture, and the clamping plate group of the fixture can clamp the workpiece 100 and penetrate into the packaging box 200, so that the workpiece 100 can be arranged in the packaging box 200. However, the fixture in the prior art is not convenient for grasping the workpiece 100, and cannot make the workpiece 100 vertically and regularly arranged inside the packaging box 200. Therefore, this embodiment also provides a fixture to solve the problem of inconvenience in clamping the workpiece 100 and inability to make the workpiece 100 regularly arranged inside the packaging box 200.
[0043] like Figure 1-Figure 8 As shown, the clamp includes a mounting member 10 and a clamping mechanism 20; specifically, at least two clamping mechanisms 20 are provided, and each clamping mechanism 20 includes a first driving member 21 and a clamping assembly 22, the mounting member 10 is connected to the top end of the clamping assembly 22, and the first driving member 21 can drive at least two clamping assemblies 22 to move along the center of the mounting member 10; the clamping assembly 22 also includes a bracket 221, a second driving member 222 and a clamping plate group, the mounting member 10 is connected to the top end of the bracket 221, the second driving member 222 and the clamping plate group are both arranged at the bottom end of the bracket 221, the clamping plate group is arranged in the vertical direction, and the end of the clamping plate group away from the bracket 221 has a guiding slope, the height of the clamping plate group in the vertical direction is not less than the height of the workpiece 100, and the second driving member 222 can drive the clamping plate group to clamp the workpiece 100.
[0044] It should be noted here that, in this embodiment, the workpiece 100 to be clamped is a self-supporting bag, and the self-supporting bag is filled with fluid. Generally, the self-supporting bag can be placed vertically on a horizontal plane. In other embodiments, this clamp can also be used to clamp other types of products, and the scope of use of the clamp is not limited in this embodiment. Therefore, the splint group is arranged in the vertical direction to facilitate the splint group to fit the self-supporting bag; secondly, the end of the clamp away from the bracket 221 is used to clamp the self-supporting bag. Since it has a guide slope, the guide slope can enable the splint group to be smoothly inserted into the gap of multiple self-supporting bags, thereby facilitating the clamping of the self-supporting bag; finally, since its height is not less than the height of the self-supporting bag, it can ensure that the self-supporting bag will not shake left and right during the clamping process, and when placed, the bottom end of the self-supporting bag can also be horizontally contacted with the bottom surface of the packaging box 200, thereby ensuring that multiple self-supporting bags can be arranged vertically and neatly in the packaging box 200.
[0045] It is further explained that in this embodiment, there are two clamping mechanisms 20, and the two clamping mechanisms 20 are arranged at intervals along the width direction of the mounting member 10 (i.e., the Y-axis direction), and the first driving member 21 can drive the clamping components 22 in the two clamping mechanisms 20 to move along the Y-axis direction, so that the clamping components 22 can shrink toward the center of the mounting member 10, so that the clamping plate group can smoothly enter the packaging box 200, thereby completing the process of clamping and packing. In other embodiments, the number and arrangement of the clamping mechanisms 20 can be adjusted according to actual needs, as long as the clamping plate group can smoothly enter the packaging box 200 after clamping the workpiece 100, and no other restrictions are made in this embodiment.
[0046] To further ensure that the clamping plate group can smoothly clamp the workpiece 100, as Figure 1 and Figure 2As shown, the clamping plate group includes a first clamping plate 225 and a second clamping plate 226, and the second driving member 222 can drive the first clamping plate 225 and / or the second clamping plate 226 to move along the X-axis and jointly clamp the workpiece 100, and the first clamping plate 225 and the second clamping plate 226 are provided with clamping plate side walls 229 on both sides of the width direction of the mounting member 10 (that is, the Y-axis direction), and a guide slope is provided at one end of the clamping plate side wall 229 away from the bracket 221. When clamping the workpiece 100, the first clamping plate 225 and the second clamping plate 226 need to be lowered to the gap between the self-supporting bags, and the first clamping plate 225 and / or the second clamping plate 226 are randomly driven to move along the X-axis through the second driving member 222 so that the two interact with each other to clamp the workpiece 100; in this process, due to the presence of the guiding inclined surface, the first clamping plate 225 and the second clamping plate 226 can be quickly inserted into the gap between the self-supporting bags, thereby facilitating clamping; in addition, since the interior of the self-supporting bag is fluid, when the first clamping plate 225 and the second clamping plate 226 clamp the self-supporting bag, they will squeeze the self-supporting bag along the X-axis direction until the self-supporting bag is completely compressed and can be grasped, and the clamping plate side walls 229 set on both sides of the first clamping plate 225 and the second clamping plate 226 can ensure that when the self-supporting bag is squeezed along the X-axis direction, the self-supporting bag will not move along the Y-axis direction, thereby ensuring a good clamping effect and making it more convenient to clamp the self-supporting bag.
[0047] like Figure 1 and Figure 2 As shown, the bracket 221 includes a support plate 2211 and a column 2212. The columns 2212 are arranged at both ends of the support plate 2211. A guide member 224 is arranged between the two columns 2212. The second driving member 222 can drive the first clamping plate 225 and / or the second clamping plate 226 to slide axially along the guide member 224.
[0048] like Figure 1 and Figure 2As shown, the support plate 2211 is used to support the mounting member 10, and the two ends of the support plate 2211 are used to connect the columns 2212, and the columns 2212 are arranged in the vertical direction. This arrangement can ensure that there is enough space between the bottom of the support plate 2211 and the columns 2212 to set other structures. Therefore, the first driving member 21 can be set at the bottom of the support plate 2211 to avoid occupying the space at the top of the support plate 2211. At the same time, the guide member 224 can be set between the two columns 2212, so that the second driving member 222 drives the first clamping plate 225 and / or the second clamping plate 226 to slide along the axial direction of the guide member 224, which can ensure that the clamping plate group moves along the preset direction, thereby ensuring a good clamping effect. It should be noted here that the second driving member 222 is arranged on the side of the column 2212 close to the support plate 2211, which can further reduce the overall size. It is further explained that at least two guide members 224 are arranged parallel to and spaced apart from each other along the Y-axis direction, and this arrangement can ensure the smoothness of the first clamping plate 225 and / or the second clamping plate 226 when sliding along the guide member 224. In other embodiments, the number of guide members 224 can be adjusted according to actual needs, and no other limitation is made in this embodiment.
[0049] To further simplify the overall structure, Figure 1 and Figure 2 As shown, the clamping assembly 22 further includes a lead screw 223, which is connected between the two columns 2212 and is arranged parallel to the bottom end of the guide member 224. The lead screw 223 can drive the first clamping plate 225 and / or the second clamping plate 226 to slide along the axial direction (i.e., the X-axis direction) of the guide member 224 and clamp the workpiece 100 by rotation, and the output end of the second driving member 222 is transmission-connected with one end of the lead screw 223. By providing the lead screw 223, the first clamping plate 225 and / or the second clamping plate 226 can be driven to move and clamp the workpiece 100 without the second driving member 222 moving itself, which is simple and convenient to use.
[0050] It should be noted here that, in order to ensure that the clamping plate group can be driven smoothly, the clamping mechanism 20 also includes a synchronization component 23, which includes a first synchronization wheel 231 and a second synchronization wheel 232. The first synchronization wheel 231 and the second synchronization wheel 232 are connected by a synchronization belt 233, and the output end of the second driving member 222 is transmission-connected to the first synchronization wheel 231, and the second synchronization wheel 232 is transmission-connected to one end of the lead screw 223, so that the second driving member 222 can rotate by driving the lead screw 223. It is further noted that the two ends of the lead screw 223 are respectively connected to the columns 2212 on both sides through the rotating bearings 28, so that the lead screw 223 can rotate under the drive of the second driving member 222 and the synchronization component 23; in addition, as Figure 2As shown, a bearing pressure plate 29 is also provided on the outer side of the rotary bearing 28, so as to ensure that the rotary bearing 28 will not fall off from the outer side of the column 2212 during use, thereby ensuring a good use effect.
[0051] It is further explained that, in this embodiment, the second driving member 222 is a rotary servo motor. Figure 1 and Figure 2 As shown, the second driving member 222 is arranged on the side of the column 2212 close to the support plate 2211, and the synchronization assembly 23 is arranged on the side of the column 2212 away from the second driving member 222. This arrangement not only facilitates the transmission connection between the second driving member 222 and the first synchronization wheel 231, but also facilitates the connection between the second synchronization wheel 232 and the lead screw 223, thereby improving the convenience of use, and at the same time makes the overall structure of the clamping assembly 22 more compact, thereby reducing space occupancy.
[0052] In addition, if Figure 1 As shown, in order to ensure that the synchronization component 23 has a good transmission effect, as shown in Figure 1 As shown, the synchronous assembly 23 also includes a tensioning wheel 234, which is arranged between the first synchronous wheel 231 and the second synchronous wheel 232, and is used to tension the synchronous belt 233. By setting the tensioning wheel 234, it is possible to ensure that the synchronous belt 233 is always in a tightened state, thereby ensuring a good transmission effect. Figure 1 As shown, the synchronous assembly 23 also includes a shield 235, which is arranged on the outside of the first synchronous wheel 231, the second synchronous wheel 232, the synchronous belt 233 and the tension wheel 234, so as to prevent the external environment from affecting the normal operation of the synchronous assembly 23, and also ensure the safety of use.
[0053] To make it more convenient to clamp the workpiece 100, Figure 2 As shown, the clamping assembly 22 includes at least two clamping plate groups, and the at least two clamping plate groups are arranged at intervals along the axial direction of the guide member 224. Each clamping plate group includes a first clamping plate 225 and a second clamping plate 226, and at least two second clamping plates 226 are fixedly arranged on the guide member 224. At least two first clamping plates 225 are transmission-connected with the lead screw 223, and the lead screw 223 is configured to be able to drive at least two first clamping plates 225 to move toward the direction of the second clamping plate 226 in each clamping plate group at the same time, so that the clamping plate group can clamp the workpiece 100. This arrangement can clamp the workpiece 100 when only the first clamping plate 225 is driven; in addition, since at least two clamping plate groups are provided, the number of workpieces 100 clamped at one time can also be increased, thereby improving the clamping efficiency.
[0054] What needs to be explained here is that Figure 1 and Figure 2As shown, in the present embodiment, the clamping assembly 22 is provided with two clamping plate groups. In other embodiments, the number of the clamping plate groups can be adjusted according to actual needs, and no other limitation is made in the present embodiment. It is further explained that, in the present embodiment, the top ends of the two first clamping plates 225 are provided with linear bearings 24, and the first clamping plates 225 are slidably connected with the guide member 224 through the linear bearings 24; the two second clamping plates 226 are fixed on the guide member 224 through the linear bearings 24. In addition, a screw sleeve 25 is also provided on the first clamping plate 225, and the screw sleeve 25 is fixed to the first clamping plate 225 through the screw sleeve fixing member 26, that is, the first clamping plate 225 is connected to the screw thread of the screw sleeve 25 and the lead screw 223 through the screw thread transmission, so that the lead screw 223 rotates to drive the first clamping plate 225 to move toward the second clamping plate 226, so as to be able to clamp the workpiece 100.
[0055] It is further explained that if Figure 2 As shown, in this embodiment, the clamping assembly 22 has two clamping plate groups, so the lead screw 223 uses a left-right rotating positive and negative trapezoidal lead screw, that is, the two ends of the lead screw 223 are provided with screw threads of different rotation directions, and the two first clamping plates 225 are respectively connected to the screw threads of different rotation directions. At this time, when the second driving member 222 drives the lead screw 223 to rotate in one direction through the synchronization assembly 23, due to the different setting directions of the screw threads, the two first clamping plates 225 can move simultaneously in the direction of approaching or away from the corresponding second clamping plate 226, thereby ensuring that the second driving member 222 can simultaneously drive the two clamping plate groups to clamp or release the workpiece 100.
[0056] like Figure 1 and Figure 2 As shown, a positioning member 227 is provided between the first clamping plate 225 and the second clamping plate 226 in each clamping plate group, and the positioning member 227 is used to locate the distance between the first clamping plate 225 and the second clamping plate 226 in each clamping plate group. The positioning member 227 is fixed to the top end of the linear bearing 24 of the first clamping plate 225 through the fixing portion 2272, and a sliding portion 2273 is provided at the top end of the linear bearing 24 of the second clamping plate 226. A guide groove 2271 is provided on the positioning member 227 between the fixing portion 2272 and the sliding portion 2273, and the sliding end of the sliding portion 2273 extends into the guide groove 2271. When the first clamping plate 225 moves toward the second clamping plate 226, the sliding portion 2273 can slide in the guide groove 2271, thereby ensuring the clamping effect. After use, the sliding portion 2273 can be directly moved to the end of the guide groove 2271 away from the fixing portion 2272. Since the length of each guide groove 2271 is the same, it can be ensured that the spacing between the first clamping plate 225 and the second clamping plate 226 in each clamping plate group is the same, thereby ensuring a good use effect.
[0057] like Figure 1As shown, the bottom of the mounting member 10 is designed with a slider 11, and the top of the clamping assembly 22 is designed with a slide groove 228, and the slider 11 is slidably connected to the slide groove 228. After each clamping mechanism 20 has clamped the workpiece 100, it is necessary to retract the multiple clamping mechanisms 20 to the center position of the mounting member 10 so that the clamping mechanisms 20 can clamp the workpiece 100 and extend into the packaging box 200. Therefore, by making the clamping assembly 22 slidably connected to the mounting member 10, the smoothness of the process can be guaranteed, thereby improving the packing efficiency. It should be noted here that, in the present embodiment, a total of two clamping mechanisms 20 are provided. In other embodiments, the number of clamping mechanisms 20 can be selected according to the opening width of the packaging box 200, and no other restrictions are made in the present embodiment.
[0058] It is further explained that, in this embodiment, the first driving member 21 is a cylinder, the protruding end of the cylinder is connected to one end of the connecting plate 27, and the other end of the connecting plate 27 is connected to the mounting member 10. Since the cylinder is arranged at the bottom end of the bracket 221, when the protruding end of the cylinder is extended or retracted, it can drive the clamping assembly 22 to move along the Y-axis direction, that is, it can make the two clamping assemblies 22 move toward the center of the mounting member 10 or toward the periphery of the mounting member 10, thereby ensuring smooth packaging.
[0059] like Figure 1 As shown, a connector 30 is provided at the top of the mounting member 10, and the fixture is conveniently connected to other driving structures through the connector 30, thereby ensuring that the fixture can be used smoothly. It should be noted here that in this embodiment, the connector 30 is a flange, which has the advantages of convenient welding and processing, low cost and ability to withstand greater tensile strength. In other embodiments, other structures such as connecting bolts are provided, as long as it can ensure that the fixture can be firmly connected to other structures, and no other limitations are made in this embodiment.
[0060] Finally combined Figure 1-Figure 8 The following describes the use process of the fixture in this embodiment:
[0061] Firstly, the first clamping plate 225 of the clamping plate group is driven by the second driving member 222 to move along the axial direction of the guide member 224 , and clamps the workpiece 100 together with the second clamping plate 226 in the same clamping plate group.
[0062] Secondly, the two clamping assemblies 22 are driven to gather toward the center of the mounting member 10 by the first driving member 21 .
[0063] Secondly, if Figure 3 and Figure 4 As shown, the clamping assembly 22 of the clamp is extended into the interior of the packaging box 200 , and the second driving member 222 drives the clamping plate group to release the workpiece 100 , so that the workpiece 100 can fall upright on the inner bottom of the packaging box 200 .
[0064] Secondly, if Figure 5 and Figure 6 As shown, the clamp is gradually moved away from the interior of the packaging box 200 .
[0065] Finally, if Figure 7 and Figure 8 As shown, after the clamping assembly 22 of the clamp is completely separated from the interior of the packaging box 200, the first clamping plate 225 and the second clamping plate 226 are restored to their original state to facilitate the next round of clamping and packing work.
[0066] In summary, the clamp of this embodiment can not only solve the problem of inconvenience in grabbing the self-supporting bag filled with fluid, but also enable the self-supporting bags to be arranged upright and neatly inside the packaging box 200 .
[0067] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
