DETAILED DESCRIPTION

[0022] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor are within the protection scope of the utility model.

[0023] In the description of the utility model, it is understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the utility model.

[0024] Please refer to Figure 1 A plate shearing machine supporting device, which is consistent with the prior art, mainly comprises a base 4, and the upper end of the base 4 is fixedly connected with a supporting piece 3 for supporting a to-be-processed plate 5.

[0025] Two groups of moving mechanisms 1 are arranged on the left and right sides of the upper end of the base 4, and each moving mechanism 1 is provided with a limiting mechanism 2 near the end, so that the to-be-processed plate 5 is placed between the two limiting mechanisms 2.

[0026] In detail, the moving mechanism 1 is composed of front-rear linear moving members and left-right linear moving members, wherein the front-rear linear moving mechanism 1 comprises a driving motor, a lead screw is arranged on the output shaft of the driving motor and is key-connected with the driving motor, and the left-right linear moving members are screwed with the lead screw through a sliding block.

[0027] Therefore, by setting the left-right linear moving members as air cylinders and fixing the limiting mechanism 2 with the movable end of the air cylinder, the front-rear and left-right linear movements of the two limiting mechanisms 2 can be realized by using the moving mechanism 1. In actual application, the configuration can realize the movement of the plate position by the cooperation of the limiting mechanism 2 and the to-be-processed plate 5, and ensure the smooth progress of the automatic processing process.

[0028] As Figure 2 , Figure 3 , Figure 4 shown, compared with the prior art device, the limiting mechanism 2 comprises a positioning piece 203 with a U-shaped structure, the vertical plane projection of the positioning piece 203 is U-shaped, and the U-shaped openings of the two positioning pieces 203 are oppositely arranged.

[0029] In addition, an activity plate 204 is arranged in the inner side of the U-shaped opening of each positioning piece 203. By ensuring that the to-be-processed plate 5 and the activity plate 204 are in the same horizontal plane and realizing the sliding connection between the activity plate 204 and the positioning piece 203, the relative movement between the positioning piece 203 and the activity plate 204 can be promoted by using the position change between the positioning piece 203 and the to-be-processed plate 5 in the process that the two limiting mechanisms 2 (i.e. the positioning pieces 203) are close to each other. Specifically, in this process, the two activity plates 204 perform opposite direction movements relative to the two positioning pieces 203, resulting in that the distance between the activity plate 204 and the inner wall of the positioning piece 203 gradually decreases.

[0030] Meanwhile, each positioning member 203 is provided with an even number of contact plates 207 on the side close to the workpiece, and the even number of contact plates 207 are symmetrically arranged above and below the horizontal center line of the positioning member 203, and each contact plate 207 is in sliding connection with the positioning member 203, and each contact plate 207 can move linearly up and down relative to the positioning member 203, so that in actual operation, the distance between the contact plate 207 and the workpiece 5 can be changed by sliding the contact plate 207, and the workpiece 5 can be clamped and fixed by the contact plate 207, and at this time, the limiting mechanism 2 and the workpiece 5 can move synchronously under the driving of the moving mechanism 1.

[0031] Therefore, in order to realize the linear up-and-down movement of the contact plate 207, each contact plate 207 is in transmission connection with the movable plate 204 through a pull rope 209, which makes it possible in actual operation that when the workpiece 5 needs to be clamped and fixed by the limiting mechanism 2, only the left-and-right linear moving member needs to be opened to force the two positioning members 203 to move relative to each other, and then the workpiece 5 can push the two movable plates 204 to move in opposite directions relative to the positioning member 203, at this time, the distance between the contact plate 207 and the workpiece 5 is reduced by the transmission effect of the pull rope 209, and the workpiece 5 can be clamped and fixed.

[0032] Specifically, each movable plate 204 is fixedly connected with a positioning rod 205 on the side away from the workpiece 5, and the positioning rod 205 is in sliding connection with the positioning member 203. Such a design makes it possible for the movable plate 204 to be in sliding connection with the positioning member 203.

[0033] Specifically, in order to achieve the sliding connection between the contact plate 207 and the positioning member 203, the device is provided with an L-shaped flow pipe 202 fixedly connected on the end of the positioning member 203 close to the workpiece 5. In this structure, a follower rod 211 is embedded in the vertical part of the flow pipe 202, and the upper end of the follower rod 211 is fixedly connected with the contact plate 207. In this way, the follower rod 211 can realize the linear up-and-down sliding connection between the contact plate 207 and the positioning member 203.

[0034] Specifically, in order to achieve the transmission connection between the movable plate 204 and the contact plate 207 (follower rod 211), the device is provided with a plurality of sealing pipes 201 on the side of the workpiece 5 of each positioning member 203, and the sealing pipes 201 correspond one-to-one with the contact plates 207.

[0035] In addition, each sealing pipe 201 is fixedly connected with the flow pipe 202 on the side of the workpiece 5, and the horizontal section of the flow pipe 202 is in communication with the inner cavity of the sealing pipe 201.

[0036] Therefore, the device is provided with the piston I 212 in the inner cavity of each flow pipe 202, and is provided with the piston II 210 in each sealing pipe 201. Meanwhile, the height of the piston II 210 is limited to be less than the height of the flow pipe 202. By further ensuring the sealing connection between the piston II 210 and the sealing pipe 201, and the sealing connection between the piston I 212 and the flow pipe 202, the up and down movement of the piston I 212 can be realized by the up and down sliding of the piston II 210 under the condition that the upper end of the piston I 212 is fixedly connected with the follow-up rod 211, so as to change the position of the contact plate 207.

[0037] It must be pointed out that, in actual operation, due to the obstruction of the to-be-processed plate 5 to the position of the contact plate 207, as shown in Figure 4 , the air volume compressed by the upward movement of the piston II 210 is much greater than the air passage volume released in the up and down movement of the piston I 212. Therefore, in actual operation, when the contact plate 207 moves upward and contacts the to-be-processed plate 5, the piston II 210 can still continue to move upward. At this time, the gas pressure in the sealing pipe 201 and the flow pipe 202 increases, thereby increasing the pressing force of the contact plate 207 on the to-be-processed plate 5, and ensuring that the limiting mechanism 2 can fully play its function.

[0038] It needs to be pointed out that, in the current situation, by fixedly connecting a sealing plate 208 to the end of the sealing pipe 201 close to the positioning member 203, it is ensured that the middle section of the pull rope 209 can be slidably and sealingly connected with the sealing plate 208. In this way, under the condition that one end of the pull rope 209 is fixedly connected with the positioning member 203, and the other end is fixedly connected with the piston II 210, the transmission connection between the movable plate 204 and the piston II 210 (contact plate 207) can be realized by using the pull rope 209.

[0039] Meanwhile, it must be pointed out that, since the gas pressure in the sealing pipe 201 and the flow pipe 202 exceeds the atmospheric pressure when the contact plate 207 contacts the to-be-processed plate 5, when the two limiting mechanisms 2 move away from each other, the pushing force of the to-be-processed plate 5 on the movable plate 204 is cancelled, and the atmospheric pressure will force the piston II 210 to reset, at this time, the pressing force of the contact plate 207 on the to-be-processed plate 5 will no longer exist.

[0040] As shown in Figure 3 , Figure 5 , further, in order to promote the rapid resetting of the contact plate 207 and prevent it from rubbing against the to-be-processed plate 5 for a long time, thereby prolonging the service life of the device, the device is additionally provided with a limiting ring 214 outside the vertical section of each flow pipe 202. The limiting ring 214 and the contact plate 207 are provided with a tension spring 213, and the two ends of the tension spring 213 are respectively detachably fixedly connected with the limiting ring 214 and the contact plate 207. In this way, the tension spring 213 can give the contact plate 207 a downward movement tendency.

[0041] Further, the vertical section of each flow pipe 202 is externally threaded, and the limiting ring 214 is detachably fixed to the flow pipe 202 through the external thread. By adjusting the position of the limiting ring 214, the minimum stretching amount of the tension spring 213 can be adjusted, and then the minimum tension force exerted by the pull rope 209 on the contact plate 207 is adjusted.

[0042] As shown in Figure 2 Further, the outer side of the positioning rod 205 is provided with a compression spring 206, and the two ends of the compression spring 206 are in contact with the movable plate 204 and the positioning member 203 respectively, so as to facilitate the rapid reset of the movable plate 204.

[0043] As shown in Figures 1-5 In the actual application process of the utility model:

[0044] Firstly, the operator accurately places the to-be-processed plate 5 on the upper side of the supporting member 3 through the corresponding mechanical control equipment (such as a mechanical hand or a pneumatic suction cup);

[0045] Then, the operator activates the left-right linear moving member, and the two limiting mechanisms 2 start to move relatively, and in this process, the movable plate 204 can push the to-be-processed plate 5 to move linearly left and right due to the action of the compression spring 206;

[0046] Subsequently, under the pushing action of the movable plate 204, the to-be-processed plate 5 continuously moves linearly left and right until the two ends of the to-be-processed plate 5 are in contact with the two movable plates 204 respectively and stop moving, at this time, the two positioning members 203 continue to move relatively, and the gap between the movable plate 204 and the inner wall of the corresponding positioning member 203 gradually decreases;

[0047] Then, as the gap between the movable plate 204 and the inner wall of the positioning member 203 continuously decreases, the distance between the contact plate 207 and the to-be-processed plate 5 also gradually decreases until the contact plate 207 is in contact with the to-be-processed plate 5 and stops moving;

[0048] Finally, as the two positioning members 203 continue to move relatively, the two pistons II 210 continue to move upward, the gas pressure inside the sealing pipe 201 and the flow pipe 202 gradually increases, and the pressing force of the contact plate 207 on the to-be-processed plate 5 gradually increases.

[0049] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
