Description

Technical Field

[0001] This utility model relates to the field of mold clamping mechanisms, specifically a mold clamping mechanism for automatic mold changing in an intelligent bending robot. Background Technology

[0002] With the acceleration of industrial automation, sheet metal bending has made breakthroughs in high intelligence, high efficiency, and high automation, and flexible automatic bending will have greater development potential. Traditional bending die changing methods are difficult to meet the above requirements; high-precision automated bending using robotic automatic die changing is the trend of intelligent bending development. The requirements for the precision, consistency, safety, and reliability of robotic automatic die changing are very high, especially the "fingers" of the automatic die changing robot—the die clamp.

[0003] Existing mold clamping mechanisms use clamping plates to clamp the mold. However, when the clamping force of the clamping plates is too great, it is difficult to protect the mold, which may cause scratches or damage to the clamped surface of the mold, thereby reducing the clamping effect. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a mold clamping mechanism for automatic mold changing in an intelligent bending robot, so as to solve the technical problem that the mold will be scratched or damaged when the clamping force on the mold is too large.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mold clamping mechanism for automatic mold changing in an intelligent bending robot, comprising a clamping body, a cylinder and a flange mounted on one side of the clamping body via hexagonal screws, a circular hole on the other side of the clamping body, and a proximity sensor installed inside the circular hole, a connector mounted on the output end of the cylinder via a piston rod, and a clamping plate provided at one end of the connector, a slot on one side of the clamping plate, an insert block inserted into the slot, and one side of the insert block being fixedly connected to the connector, and protective pads provided on one side of the clamping plate and the other side of the clamping body.

[0006] By adopting the above technical solution, during operation, the cylinder works to extend the piston rod, which in turn drives the connector and clamping plate to move. The robot extends the clamping plate into and through the mold unloading long hole, and the side of the clamping plate exceeds the mold button surface. The robot then raises the mold clamping mechanism.

[0007] Furthermore, a locking bolt extending into the insert is installed at the bottom of the clamping plate.

[0008] By adopting the above technical solution, once the locking bolt is screwed into the insert, the insert can be locked and limited, thus completing the installation of the clamp.

[0009] Furthermore, the clamp and the connector form an "L"-shaped structure, and the clamp and the connector are detachably connected.

[0010] By adopting the above technical solution, the clamping plate can hold the mold, and the clamping plate can be removed from the connector head for replacement.

[0011] Furthermore, the clamp body has an elongated waist-shaped hole inside, through which the piston rod passes.

[0012] By adopting the above technical solution, the piston rod can move smoothly within the clamp body.

[0013] Furthermore, the end face of the proximity sensor is flush with the end face of the clamp body.

[0014] By adopting the above technical solution, the clamp body can cooperate with the clamping plate to clamp and limit the mold.

[0015] Furthermore, the clamp body and the cylinder are fixedly connected to the mold-changing robot arm via a flange.

[0016] By adopting the above technical solution, the flange setting facilitates the connection of the clamp body and cylinder to the mold changing robot arm.

[0017] Furthermore, the proximity sensor is connected to the mold-changing robot control system.

[0018] By adopting the above technical solution, the proximity sensor feeds back the clamping status signal to the robot, and the robot moves the mold.

[0019] Furthermore, an air pipe connector is connected to the top of the cylinder, and the cylinder is connected to the pneumatic system of the mold-changing robot.

[0020] By adopting the above technical solution, the tracheal connector is designed to connect to the tracheal tube.

[0021] Furthermore, the plug is adapted to the slot.

[0022] By adopting the above technical solution, when installing the clamping plate, simply insert the insert block into the slot to complete the positioning of the clamping plate, which is convenient for subsequent locking with locking bolts.

[0023] Furthermore, the protective pad is made of rubber material, and the protective pad on the other side of the clamp body is connected to the clamp body by fastening bolts.

[0024] By adopting the above technical solution, the protective pad can protect the mold and prevent excessive clamping force from damaging the mold.

[0025] In summary, the present invention has the following main advantages:

[0026] 1. This utility model has a protective pad, which can protect the clamped surface of the mold and prevent excessive clamping force from damaging the mold, thereby improving the clamping and protection effect of the mold.

[0027] 2. This utility model is equipped with a plug, a slot and a locking bolt. When a damaged clamp needs to be replaced, the worker only needs to turn the locking bolt to unscrew it from the plug, and then pull the clamp to separate the clamp from the connector. In this way, the clamp can be removed for replacement of the damaged clamp.

[0028] 3. This utility model is equipped with fastening bolts. Since the clamp plate can be disassembled and replaced, the protective pad on the clamp plate can be replaced. When it is necessary to replace the protective pad on the clamp body, simply unscrew the fastening bolts from the clamp body and then remove the protective pad to replace the damaged protective pad.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0038] The embodiments of this utility model will be described below based on its overall structure.

[0039] Example 1:

[0040] A mold clamping mechanism for automatic mold changing in an intelligent bending robot, such as Figures 1-7 As shown, the device includes a clamp body 1. A cylinder 2 and a flange 3 are mounted on one side of the clamp body 1 via hexagonal screws 10. A circular hole 13 is provided on the other side of the clamp body 1, and a proximity sensor 5 is installed inside the circular hole 13. A connector 6 is mounted on the output end of the cylinder 2 via a piston rod 14, and a clamping plate 7 is provided on one end of the connector 6. During operation, the cylinder 2 operates to extend the piston rod 14, thereby driving the connector 6 and the clamping plate 7 to move. The robot extends the clamping plate 7 into and through the mold unloading elongated hole. The side of the clamping plate 7 extends beyond the mold button surface. The robot raises the mold clamping mechanism. The clamping plate 7 and the connector 6 form an "L"-shaped structure. The clamping plate 7 can be detached from the connector 6. The clamping plate 7 can clamp the mold, and the clamping plate 7 can be removed from the connector 6 for replacement.

[0041] See Figures 1-6 The clamp body 1 has an elongated slot 12 inside, through which the piston rod 14 passes, allowing the piston rod 14 to move smoothly within the clamp body 1. The end face of the proximity sensor 5 is flush with the end face of the clamp body 1, so that the clamp body 1 can cooperate with the clamping plate 7 to clamp and limit the mold. The clamp body 1 and the cylinder 2 are fixedly connected to the mold changing robot arm via a flange 3. The flange 3 facilitates the connection between the clamp body 1 and the cylinder 2 and the mold changing robot arm. The proximity sensor 5 is connected to the mold changing robot control system and feeds back the clamping status signal to the robot, which then moves the mold. The top of the cylinder 2 is connected to an air pipe connector 4, which connects the cylinder 2 to the pneumatic system of the mold changing robot. The air pipe connector 4 facilitates connection to an air pipe. Protective pads 15 are provided on one side of the clamping plate 7 and the other side of the clamp body 1. The protective pads 15 are made of rubber and can protect the mold from damage caused by excessive clamping force.

[0042] Example 2:

[0043] Based on the above embodiment 1, the following structure will be set to facilitate the disassembly and replacement of the clamping plate 7.

[0044] See Figures 2-7A slot 9 is provided on one side of the clamp plate 7. A plug 8 is inserted into the slot 9, and one side of the plug 8 is fixedly connected to the connector 6. The plug 8 is adapted to the slot 9. When installing the clamp plate 7, simply insert the plug 8 into the slot 9 to complete the positioning of the clamp plate 7, which is convenient for subsequent locking with the locking bolt 11. The bottom of the clamp plate 7 is equipped with a locking bolt 11 that extends into the plug 8. When the locking bolt 11 is screwed into the plug 8, the plug 8 can be locked and limited, thus completing the installation of the clamp plate 7.

[0045] Example 3:

[0046] Based on the above embodiment 1, the following structure will be set to facilitate the replacement of the protective pad 15 on the clamp body 1.

[0047] Specifically, the protective pad 15 on the other side of the clamp body 1 is connected to the clamp body 1 by a fastening bolt 16, which facilitates the removal and replacement of the protective pad 15 on the clamp body 1.

[0048] The working principle of this utility model is as follows: First, when in use, the operator can fix the clamping mechanism to the mold changing robot arm through the flange 3, connect the proximity sensor 5 to the mold changing robot control system, and connect the cylinder 2 to the mold changing robot pneumatic system. When working, the cylinder 2 is started, and the piston rod is extended, which in turn drives the connector 6 and the clamping plate 7 to move. The robot extends the clamping plate 7 into and through the mold unloading hole. The side of the clamping plate 7 exceeds the mold button surface. The robot raises the mold clamping mechanism, and the end face of the clamping body 1 is pressed against the mold surface. At this time, the cylinder 2 works to retract the piston rod, and the clamping plate 7 presses the mold. The proximity sensor 5 detects the clamping state of the clamping plate and feeds back the clamping state signal to the robot. The robot moves the mold to realize the loading and unloading of the mold, while the protective pad 15 can protect the clamped surface of the mold.

[0049] When the damaged clamp 7 needs to be replaced, the worker only needs to turn the locking bolt 11 to unscrew the locking bolt 11 from the insert block 8, and then pull the clamp 7 to separate the clamp 7 from the connector 6, so that the clamp 7 can be removed for replacement.
