Description

Technical Field

[0001] The utility model relates to the technical field of fatigue testing of container lids, in particular to a positioning device for fatigue testing of container lids. Background Technique

[0002] At present, container lids are divided into two types. In order to test the fatigue resistance of container lids, container lids need to be tested for fatigue resistance through a fatigue testing device. Since container lids are divided into flip lids and screw caps, container lid fatigue testing devices are also divided into two types, resulting in different positioning devices for container lids on the fatigue testing device. Moreover, the shapes of container lids are diverse. Therefore, the positioning devices on some container lid fatigue testing devices require manual operation by staff, which is cumbersome. Content of the Utility Model

[0003] The purpose of the utility model is to provide a positioning device for fatigue testing of container lids to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A positioning device for fatigue testing of container lids, including a mounting plate. An induction structure is arranged on the outer side of the mounting plate. Moving positioning structures are arranged on both sides and at both ends of the bottom of the mounting plate. A second electric cylinder is installed at the middle position of the bottom of the mounting plate, and a suction cup is installed at the output end of the second electric cylinder.

[0005] By adopting the above technical solution, the induction structure detects the position of the container lid on the mounting plate, enabling the moving positioning structure to adjust the position of the container lid on the mounting plate when clamping and fixing the container lid. And through the cooperation between the second electric cylinder and the suction cup, the suction cup can further fix the position of the container lid on the mounting plate.

[0006] Preferably, the induction structure on the mounting plate includes a rodless electric cylinder. Rodless electric cylinders are installed at both sides and at both ends of the mounting plate near the top corners. A connecting piece is installed at the output end of the rodless electric cylinder, and a laser sensor is installed on the rodless electric cylinder through the connecting piece.

[0007] By adopting the above technical solution, the laser sensors on the rodless electric cylinders opposite to each other on the mounting plate move synchronously. When the container lid is clamped and fixed on the mounting plate, if the position of the container lid deviates, the laser sensor will be triggered.

[0008] Preferably, the moving and positioning structure on the mounting plate includes motors. Motors are installed at the middle positions on both sides and at both ends of the bottom of the mounting plate. There are eight motors, with four in a group, and the two groups of motors are installed in opposite directions. The output ends of the motors are installed with lead screws. A moving block is movably installed on the outer surface of the lead screws. A clamping member is rotatably installed on the outer side of the bottom end of the moving block. First electric cylinders are installed on both sides and at both ends of the bottom of the mounting plate near the lead screws. The output ends of the first electric cylinders are installed with limiting plates. A detachable clamping rod is rotatably installed at the middle position of the top of the moving block.

[0009] By adopting the above technical solution, the rotation of the output end of the motor drives the lead screw to rotate, enabling the moving block to move along the lead screw, so that the clamping rod can fix the container lid on the mounting plate. At the same time, the cooperation between the clamping member and the limiting plate prevents the moving block from sliding when clamping and fixing the container lid. Moreover, when the staff disassembles the container lid from the mounting plate, the staff can drive the limiting plate to move by the contraction of the output end of the first electric cylinder, thereby releasing the lock between the clamping member and the limiting plate. The output end of the motor rotates in the reverse direction, and the staff can then disassemble the container lid from the mounting plate.

[0010] Preferably, the clamping rod includes a rotating member. A rotating member is rotatably installed at the middle position of the top of the moving block. A pressure sensor is installed at the top of one side of the rotating member. An anti-slip rubber sleeve is installed at the top of the outer surface of the rotating member.

[0011] By adopting the above technical solution, a pressure sensor is provided on the rotating member. When the clamping rod clamps and fixes the container lid, if the pressure sensor is squeezed, the motor is turned off to prevent the container lid from being damaged due to excessive squeezing by the clamping rod.

[0012] Preferably, the output end of the second electric cylinder passes through the mounting plate and is connected to the suction cup. Grooves are provided on both sides and at both ends of the top of the mounting plate. The connecting member is slidably connected to the mounting plate through the grooves. A rectangular opening is provided on the side of the connecting member close to the mounting plate. The connecting member is connected to the laser sensor through the rectangular opening.

[0013] By adopting the above technical solution, after the container lid is fixed on the mounting plate, the output end of the second electric cylinder pushes the suction cup upward, enabling the suction cup to further fix the container lid.

[0014] Preferably, a plurality of mounting grooves are provided at the bottom of the mounting plate. The mounting plate is connected to the motor through the mounting grooves. A limiting groove is provided on one side of the bottom of the moving block close to the limiting plate. The moving block is rotatably connected to the clamping member through the limiting groove. The clamping member is engaged with the limiting plate. A rotating groove is provided at the middle position of the top of the moving block. The moving block is rotatably connected to the rotating member through the rotating groove.

[0015] By adopting the above technical solution, the clamping member is composed of a return spring and a clamping plate, and the limiting groove can serve the purpose of restricting the rotation range of the clamping member.

[0016] Preferably, moving grooves are provided on both sides and both ends of the top of the mounting plate. The moving block is slidably connected to the mounting plate through the moving groove. A connecting groove is provided on the end surface of the moving groove in the mounting plate, and the lead screw is rotatably connected to the mounting plate through the connecting groove.

[0017] By adopting the above technical solution, the lead screw rotates in the moving groove, causing the moving block to move in the moving groove. The moving groove serves the purpose of restricting the moving range of the moving block, and through the cooperation of the moving groove, the moving block can avoid flipping when moving along the lead screw.

[0018] Preferably, one end of the anti-slip rubber sleeve is provided with an arc surface. The arc surfaces of the anti-slip rubber sleeves on the same side or the same end of the anti-slip rubber sleeve are installed in the opposite direction. A rectangular groove is provided at one end of the anti-slip rubber sleeve near the arc surface, and the size of the pressure sensor is slightly smaller than the size of the rectangular groove on the anti-slip rubber sleeve.

[0019] By adopting the above technical solution, when the arc surface on the anti-slip rubber sleeve clamps and fixes the container lid, the anti-slip rubber sleeve can drive the rotating member on the clamping rod to rotate through the assistance of the arc surface, so that the flat surface on the anti-slip rubber sleeve can closely adhere to the inner wall or the outer wall of the container lid, avoiding the situation of the container lid sliding during the fatigue test of the container lid.

[0020] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0021] The positioning device for fatigue testing of the container lid is provided with two groups of moving and positioning structures. The motor drives the lead screw to make the moving blocks on the two groups of moving and positioning structures move in the same direction, so that the container lid can be fixed on the mounting plate. Moreover, the moving and positioning structures can clamp and fix the inner wall and the outer wall of the container lid. At the same time, through the cooperation between the second electric cylinder and the suction cup, the container lid is further assisted to be fixed on the mounting plate.

[0022] The positioning device for fatigue testing of the container lid is provided with an induction structure. During the process of fixing and clamping the container lid on the mounting plate, the induction structure can sense the position of the container lid on the mounting plate. When the position of the fixed sandwich layer of the container lid deviates, the induction structure is triggered, and the moving and positioning structures adjust the position of the container lid on the mounting plate accordingly.

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] In this embodiment, the induction structure on the mounting plate 1 includes a rodless electric cylinder 2, rodless electric cylinders 2 are installed at both sides and both ends of the mounting plate 1 near the top corners, a connecting piece 3 is installed at the output end of the rodless electric cylinder 2, a laser sensor 4 is installed on the rodless electric cylinder 2 through the connecting piece 3, the laser sensors 4 on the rodless electric cylinders 2 opposite to each other on the mounting plate 1 move synchronously, when the container lid is clamped and fixed on the mounting plate 1, if the position of the container lid deviates, the laser sensor 4 will be triggered.

[0033] In this embodiment, the moving and positioning structure on the mounting plate 1 includes a motor 5. The motors 5 are installed at the two sides and the middle positions of the two ends at the bottom of the mounting plate 1. There are eight motors 5, with four in a group, and the two groups of motors 5 are installed in opposite directions. The output end of the motor 5 is installed with a lead screw 6. A moving block 7 is movably installed on the outer surface of the lead screw 6. A clamping member 71 is rotatably installed on the outer side of the bottom end of the moving block 7. The first electric cylinders 8 are installed on both sides and at both ends of the bottom of the mounting plate 1 near the lead screw 6. The output end of the first electric cylinder 8 is installed with a limiting plate 9. A detachable clamping rod 10 is rotatably installed at the middle position of the top of the moving block 7. The moving block 7 drives the lead screw 6 to rotate through the rotation of the output end of the motor 5, so that the moving block 7 can move along the lead screw 6, enabling the clamping rod 10 to fix the container lid on the mounting plate 1. At the same time, the cooperation between the clamping member 71 and the limiting plate 9 prevents the moving block 7 from sliding when clamping and fixing the container lid. Moreover, when the staff disassembles the container lid from the mounting plate 1, the staff can drive the limiting plate 9 to move through the contraction of the output end of the first electric cylinder 8, thereby releasing the lock between the clamping member 71 and the limiting plate 9. The output end of the motor 5 rotates in the reverse direction, and the staff can disassemble the container lid from the mounting plate 1.

[0034] In this embodiment, the clamping rod 10 includes a rotating member 11. The rotating member 11 is rotatably installed at the middle position of the top of the moving block 7. A pressure sensor 12 is installed at the top of one side of the rotating member 11. An anti-slip rubber sleeve 13 is installed at the top of the outer surface of the rotating member 11. When the pressure sensor 12 is provided on the rotating member 11 and the clamping rod 10 clamps and fixes the container lid, if the pressure sensor 12 is squeezed, the motor 5 is turned off to prevent the container lid from being damaged due to excessive squeezing by the clamping rod 10.

[0035] In this embodiment, the output end of the second electric cylinder 20 penetrates through the mounting plate 1 and is connected to the suction cup 21. Grooves are provided on both sides and at both ends of the top of the mounting plate 1. The connecting member 3 is slidably connected to the mounting plate 1 through the grooves. A rectangular opening is provided on the side of the connecting member 3 close to the mounting plate 1. The connecting member 3 is connected to the laser sensor 4 through the rectangular opening. After the container lid is fixed on the mounting plate 1, the output end of the second electric cylinder 20 pushes the suction cup 21 to rise, enabling the suction cup 21 to further fix the container lid.

[0036] In this embodiment, a plurality of mounting grooves are provided at the bottom of the mounting plate 1. The mounting plate 1 is connected to the motor 5 through the mounting grooves. A limiting groove is provided on one side of the bottom of the moving block 7 close to the limiting plate 9. The moving block 7 is rotatably connected to the clamping member 71 through the limiting groove. The clamping member 71 is engaged with the limiting plate 9. A rotating groove is provided at the middle position of the top of the moving block 7. The moving block 7 is rotatably connected to the rotating member 11 through the rotating groove. The clamping member 71 is composed of a return spring and a clamping plate, and the limiting groove can limit the rotation range of the clamping member 71.

[0037] In this embodiment, moving grooves are formed on both sides and both ends of the top of the mounting plate 1. The moving block 7 is slidably connected to the mounting plate 1 through the moving grooves. A connecting groove is formed on the end surface of the moving groove in the mounting plate 1. The lead screw 6 is rotatably connected to the mounting plate 1 through the connecting groove. The lead screw 6 rotates in the moving groove to move the moving block 7 in the moving groove. The moving groove serves to limit the moving range of the moving block 7. And through the cooperation of the moving groove, when the moving block 7 moves along the lead screw 6, the situation of the moving block 7 flipping can be avoided.

[0038] In this embodiment, one end of the anti-slip rubber sleeve 13 is provided with an arc surface. The arc surfaces of the anti-slip rubber sleeves 13 on the same side or the same end of the anti-slip rubber sleeve 13 are installed in the reverse direction. A rectangular groove is formed at one end of the anti-slip rubber sleeve 13 near the arc surface. The size of the pressure sensor 12 is slightly smaller than the size of the rectangular groove on the anti-slip rubber sleeve 13. When the arc surface of the anti-slip rubber sleeve 13 clamps and fixes the container lid, the anti-slip rubber sleeve 13 can drive the rotating member 11 on the clamping rod 10 to rotate through the assistance of the arc surface, so that the flat surface of the anti-slip rubber sleeve 13 can closely adhere to the inner wall or the outer wall of the container lid, avoiding the situation of the container lid sliding during the fatigue test of the container lid. And the anti-slip rubber sleeve 13 adjusts the structure of the anti-slip rubber sleeve 13 according to the external shape of the container lid. A step is arranged on the side of the anti-slip rubber sleeve 13 close to the container lid, so that when the anti-slip rubber sleeve 13 contacts the container lid, the contact area between the anti-slip rubber sleeve 13 and the container lid is increased, and the stability of the clamping rod 10 to the container lid is further improved.

[0039] Example 2, as Figures 2-3 shown, two sets of moving and positioning structures are arranged on the mounting plate 1. One set of moving and positioning structures is close to the rodless cylinder 2, and the other set of moving and positioning structures is far from the rodless cylinder 2. If positioning a container lid with a larger size, the user can clamp and fix the inner wall and the outer wall of the container lid through the two sets of moving and positioning structures. If positioning a container lid with a smaller size, the user can remove the clamping rod 10 on one set of moving and positioning structures close to the rodless cylinder 2 and clamp and fix the container lid with a smaller size with one set of moving and positioning structures far from the rodless cylinder 2. If positioning an irregular-shaped container lid, the user can remove the clamping rod 10 on one set of moving and positioning structures far from the rodless cylinder 2 and clamp and position the irregular-shaped container lid with one set of moving and positioning structures close to the rodless cylinder 2, so that the clamping rod can be used multifunctionally.

[0040] Working principle: The staff places the container lid on the mounting plate 1, starts the motor 5 to drive the lead screw 6 to rotate, so that the moving block 7 moves towards the container lid. At the same time, the rodless cylinder 2 is also started, so that the laser sensor 4 on the output end of the rodless cylinder 2 moves towards the middle position of the mounting plate 1. If the position of the container lid on the mounting plate 1 is deviated, the laser sensor 4 will be triggered, and the rotation speed of the output end of the motor 5 opposite to the deviation position will be increased, so that the clamping rod 10 on the moving block 7 can adjust the position of the container lid. Moreover, when the container lid is excessively squeezed by the clamping rod 10, the pressure sensor 12 is triggered to turn off the motor 5 to prevent the container lid from being damaged due to excessive squeezing.
