Description

Technical Field

[0001] The present application relates to the technical field of assembly and production of construction engineering parts, and in particular to a pipe clamping sleeve grabbing device dedicated to ALC boards. Background Art

[0002] ALC board, a building material, is widely used in earthquake-resistant buildings due to its advantages of light weight, high strength, thermal insulation, fireproofing and sound insulation. ALC board is mainly used in building exterior walls, interior walls, floor slabs, partition walls, etc.

[0003] ALC board special pipe clamps are used when installing ALC board. ALC board special pipe clamps are composed of two parts: sleeve and gasket. During production, the corresponding position of the gasket is pre-punched, and then the sleeve end is reduced in diameter and inserted into the hole of the gasket and riveted and fixed.

[0004] In actual production, especially in the final riveting and assembly process, workers usually manually place the casing on the riveting and shrinking equipment, and then manually place the gasket on the casing after shrinking the casing end, so that the reduced diameter part of the casing passes through the hole of the gasket, and then rivet and fix it. During the final riveting process, workers need to keep holding the gasket by hand, which not only reduces the construction efficiency but also reduces safety.

[0005] The production process of ALC board special pipe clamps can be divided into the following steps: casing production, casing cutting, casing loading and automatic placement, gasket cutting, gasket punching, gasket automatic loading, gasket and casing automatic combination riveting. Since there is no complete set of automatic riveting and assembly equipment for ALC board special pipe clamps, if automatic production is to be realized, the above links need to be designed by ourselves.

[0006] Among them, the last step of casing production is cutting, cutting the casing into specified lengths. Finally, the casing needs to be moved to the corresponding station and fixed for diameter reduction, and then the punched gasket is placed on the riveting station for riveting and fixing. When the casing is placed on the station, it is generally required to be in a vertical state to facilitate subsequent diameter reduction and riveting. Among them, the operation of moving the casing to the corresponding station has always been performed manually, which is also the part with the highest safety factor in the entire production process. On the other hand, since the workers manually take the casing and move it to the station for fixing, the long-term operation of the entire process will lead to reduced production efficiency. Therefore, how to automatically, efficiently and at a lower cost realize the automatic grasping and moving of the casing and place it on the corresponding station has become an important part of the design of the automated production line for ALC board special pipe clamps.

During the resetting process of the sliding block, the one-way rotation setting of the main bearing will not drive the switching shaft to continue to rotate, so that the grab plate remains in an open state and flips and moves downward. When the second rack meshes with the main bearing and drives the switching shaft to rotate, the grab plate clamps the sleeve. In this way, the automatic grabbing and releasing of the sleeve by the grabbing device through the stroke is effectively realized;

[0043] The opposite arrangement of the main bearing and the auxiliary bearing can not only make the switching shaft rotate in one direction, thus improving the stability of the position of the diamond-shaped protrusion, but also prevent the switching shaft from rotating during the resetting process of the sliding block and the mounting platform, so that the main bearing can rotate idly, thereby improving the stability of the state of the grab plate, so as to achieve the stability of the process of automatic grabbing and putting down of the grab plate by using the stroke;

[0044] The arrangement of the guide rod, the flipping strip hole and the flipping hole enables the grabbing device to achieve sliding and flipping only under the action of the driving cylinder, which not only reduces the equipment cost but also effectively ensures the stability of the movement.

A mounting plate 41 is fixedly provided on the upper surface of the mounting platform 4 on the side of the sliding block 44 away from the diameter reduction station 3, and a driving cylinder 411 is installed on the mounting plate 41. The driving cylinder 411 is horizontally arranged and parallel to the sliding direction of the sliding block 44. A T-slot 443 is provided on the side wall of the sliding block 44, and the T-slot 443 is opened toward one side of the driving cylinder 411. A T-block 444 is slidably connected in the T-slot 443, and the piston rod of the driving cylinder 411 is installed and connected to the T-block 444.

[0059] refer to Figure 3 and Figure 4 A guide plate 42 parallel to the sliding direction of the sliding block 44 is installed on one side of the sliding block 44 of the mounting platform 4. A flip bar hole 421 is provided on the side wall of the guide plate 42 along the sliding direction of the sliding block 44. A vertically arranged flip hole 422 is provided on the top of one end of the flip bar hole 421 facing the mounting plate 41. The flip hole 422 is connected to the flip bar hole 421 and is arranged in an arc transition. A stabilizing bearing 442 is installed in the middle of the sliding block 44. The rotation axis of the stabilizing bearing 442 is arranged horizontally and perpendicular to the sliding direction of the sliding block 44. A flip shaft 441 is rotatably connected in the stabilizing bearing 442. A mounting block 4411 is fixedly provided on the flip shaft 441 at one end of the sliding block 44 away from the guide plate 42, and the grabbing device 5 is installed on the mounting block 4411. A flip plate 4412 is fixedly provided at one end of the flip shaft 441 close to the guide plate 42, and a guide rod 4413 is fixedly provided on the flip plate 4412. The guide rod 4413 is arranged parallel to the central axis of the flip rod, and the guide rod 4413 extends into the flip bar hole 421. The guide rod 4413 is rotatably connected to a guide bearing 4414, and the outer wall of the guide bearing 4414 abuts against the inner wall of the flip bar hole 421 and the flip hole 422.

[0060] The grabbing device 5 is a device capable of grabbing the sleeve, and can be a pneumatic finger, an electromagnetic manipulator, etc., and the present embodiment is a pneumatic finger. When the guide rod 4413 is located in the flip hole 422, the sleeve grabbed by the grabbing device 5 is in a horizontal state and is located above the sleeve intercepted by the baffle 13 on the conveyor belt 11. When the guide rod 4413 is located in the flip bar hole 421, the sleeve grabbed by the grabbing device 5 is in a vertical state and can be moved above the diameter reduction station 3.

[0061] The feeding device 2 moves the sleeve onto the conveyor belt 11, and the sleeve is conveyed while being laid down on the conveyor belt 11 and intercepted by the baffle 13, wherein the setting of the guard plate 12 can effectively improve the stability of the sleeve moving on the conveyor belt 11. The driving cylinder 411 drives the sliding block 44 to move to a position where the guide rod 4413 is located in the flip hole 422, and then the flip shaft 441 is rotated through the rotation relationship of the flip plate 4412, and then the grabbing device 5 is rotated downward. Then the lifting cylinder 14 drives the mounting platform 4 to move downward, so that the grabbing device 5 is located at the sleeve intercepted by the baffle 13 and grabs the sleeve. Then the mounting platform 4 moves upward, and the piston rod of the driving cylinder 411 extends, so that the sliding block 44 slides, and the guide rod 4413 is located in the flip bar hole 421 from the flip hole 422, so that the grabbing device 5 is rotated upward to a horizontal state, and the process of flipping the sleeve to a vertical state is realized. The driving cylinder 411 drives the sliding block 44 to slide to the position above the reducing station 3 and then releases the sleeve, and the sleeve is automatically placed on the reducing station 3, thereby realizing the automatic placement of the sleeve on the reducing station 3, realizing the automation of the process, and improving the safety and efficiency of the automatic riveting and pressing combination production of the sleeve of the ALC board special pipe clamp.

[0062] The arrangement of the stabilizing bearing 442 and the guide bearing 4414 effectively improves the stability of the movement of the flip shaft 441 and the guide rod 4413 in the flip bar hole 421 and the flip hole 422. The arrangement of the flip hole 422 and the flip bar hole 421 on the guide plate 42 cooperates with the arrangement of the flip plate 4412 and the guide rod 4413, and effectively utilizes the stroke of the sliding block 44 to realize the flipping of the grabbing device 5. The arrangement of the T-block 444 realizes the detachable installation and fixation of the piston rod of the driving cylinder 411 and the sliding block 44, which is convenient for subsequent maintenance.

[0063] refer to Figure 4 The mounting platform 4 is fixed with a protective plate 43, which is located on the side of the sliding block 44 away from the mounting plate 41 and is arranged opposite to the mounting plate 41. The protective plate 43 and the mounting plate 41 are both fixedly connected to the guide plate 42. Buffers 431 are installed on the protective plate 43 and the mounting plate 41, and the buffer heads of the buffers 431 are facing the sliding block 44. The provision of the protective plate 43 enables the protective plate 43, the guide plate 42 and the mounting plate 41 to form a frame structure, thereby improving the installation stability of the stressed guide plate 42 and the mounting plate 41. On the other hand, the buffer 431 can be installed on the protective plate 43 and the mounting plate 41, thereby improving the protection of the piston rod extension and contraction of the drive cylinder 411 and the sliding of the sliding block 44.

[0064] refer to Figure 4The equipment frame 1 is fixedly provided with first vertical plates 16 on both sides of the jacking cylinder 14, the first vertical plates 16 abut against the jacking cylinder 14 and provide a mounting position for the jacking cylinder 14, and the lower surface of the mounting platform 4 is fixedly provided with second vertical plates 17, the second vertical plates 17 are slidably connected with the first vertical plates 16.

[0065] The implementation principle of the embodiment 1 of the present application is as follows: the feeding device 2 moves the sleeve onto the conveyor belt 11 and then conveys the sleeve to the baffle 13. After the driving cylinder 411 drives the sliding block 44 to move so that the grabbing device 5 is in a vertical state, the lifting cylinder 14 drives the installation platform 4 to move downward, so that the grabbing device 5 grabs the sleeve intercepted by the baffle 13. Then the lifting cylinder 14 drives the lifting platform upward, the driving cylinder 411 drives the sliding block 44 to slide, and the guide rod 4413 slides from the flip hole 422 to the flip bar hole 421 to realize the flipping of the grabbing device 5. Then the grabbing device 5 moves the sleeve to the top of the reducing station 3 and then releases the sleeve, realizing the operation of automatically grabbing, flipping and placing the sleeve on the reducing station 3, thereby improving the safety and operating efficiency of this link, and thus improving the efficiency of the riveting and pressing assembly of the special pipe clamp for the ALC board. Example

[0066] refer to Figure 5 and Figure 6, the difference between this embodiment and embodiment 1 is that the grabbing device 5 includes a main board 51 and a grabbing plate 52. The main board 51 is mounted on the mounting block 4411. When the main board 51 is in a horizontal state, the guide rod 4413 is located in the flip bar hole 421. At this time, a sliding groove 511 is provided at one end of the main board 51 facing the diameter reduction station 3. There are two grabbing plates 52, which are slidably connected in the sliding groove 511, and the two grabbing plates 52 are arranged opposite to each other. An inner cavity 512 is provided inside the main board 51, and a compression spring 5122 is fixedly provided on the inner wall of the inner cavity 512 close to the sliding groove 511. A tensioning block 5121 is fixedly provided at the other end of the compression spring 5122, and the compression spring 5122 presses the tensioning block 5121 to the other side. The main board 51 is provided with a rotating cavity 513 connected to the sliding groove 511, and the rotating cavity 513 is provided with a middle hole 5131 connected to the inner cavity 512. The rotating chamber 513 is rotatably connected to two bending plates 5132, and the bending plates 5132 are "L" shaped. The two bending plates 5132 are symmetrically arranged, and the rotation axis of the bending plates 5132 is located at the middle bending part of the bending plates 5132. One end of the bending plate 5132 penetrates into the sliding groove 511 and is rotatably connected to the grabbing plate 52. A tensioning column 5133 is slidably connected in the middle hole 5131, and the tensioning column 5133 is fixedly connected to the tensioning block 5121. The other end of the tensioning column 5133 is rotatably connected to the two bending plates 5132, and the compression spring 5122 can press the two grabbing plates 52 against each other through the tensioning block 5121, the tensioning column 5133 and the bending plates 5132. The force of the two grabbing plates 52 pressing against each other is sufficient to stably clamp the sleeve. The main board 51 is provided with a switching component 6 for controlling the opening of the two grabbing plates 52.

[0067] refer to Figure 6 and Figure 7 The switching assembly 6 includes a switching rod 61 and a diamond-shaped protrusion 62. The main board 51 is provided with a switching hole 5111 connected to the middle of the sliding groove 511. The switching rod 61 is rotatably connected in the switching hole 5111, and the diamond-shaped protrusion 62 is fixed to one end of the switching rod 61 located in the sliding groove 511. The end of the diamond-shaped protrusion 62 that is shorter than the center of itself is the short end, and the end that is longer than the center of itself is the long end. When the short end of the diamond-shaped protrusion 62 is opposite to the grab plate 52, the grab plate 52 can clamp the sleeve, and when the long end of the diamond-shaped protrusion 62 is in contact with the grab plate 52, the sleeve can be moved out from between the grab plates 52. One end of the switching rod 61 located outside the sliding groove 511 is rotatably connected to the main bearing 611, and the circumferential outer wall of the main bearing 611 is distributed with teeth, and the main bearing 611 is a one-way bearing. The main plate 51 is fixedly provided with a secondary bearing 612 , which is rotatably connected and abutted against the switching shaft. The secondary bearing 612 is a one-way bearing and is installed in the opposite direction to the main bearing 611 .

[0068] The mounting platform 4 is provided with a first rack 45 above the main board 51. When the first rack 45 is engaged with the teeth of the main bearing 611, the sleeve is located above the reduction station 3. The equipment frame 1 is provided with a second rack 15 below the mounting platform 4. When the sleeve on the conveyor belt 11 is located between the grab plates 52, the second rack 15 is engaged with the teeth of the main bearing 611, and the sleeve is separated when the grooves of the grab plates 52 are completely opposite to each other. When the main board 51 moves toward the reduction station 3, when the main bearing 611 is engaged with the first rack 45, the main bearing 611 is relatively fixed to the switching shaft. When the main board 51 moves toward the conveyor belt 11, when the main bearing 611 is engaged with the second rack 15, the main bearing 611 is relatively fixed to the switching shaft.

[0069] In the main board 51, due to the tensioning relationship between the compression spring 5122 and the tensioning block 5121, the tensioning block 5121 drives the two bending plates 5132 to rotate through the tensioning column 5133, so that the two grab plates 52 are pressed against each other, so that the grab plates 52 always maintain the force to clamp the sleeve. In the process of the installation platform 4 moving downward, the main board 51 is in a vertical state and the grab plates 52 are in contact with the long ends of the diamond-shaped protrusions 62, and the two grab plates 52 are in an open state. When the main board 51 moves down to the sleeve between the grab plates 52, the second rack 15 is meshed with the main bearing 611 and drives the switching rod 61 to rotate through the main bearing 611. The switching rod 61 drives the diamond-shaped protrusions 62 to rotate, and under the pressure of the two grab plates 52, it also assists in driving the diamond-shaped protrusions 62 to rotate. After the second rack 15 is separated from the main bearing 611, the grabbing part of the grab plate 52 moves to a position opposite to the sleeve and automatically clamps the sleeve. In the subsequent upward movement process, since the main bearing 611 is a one-way bearing, the engagement with the second rack 15 will not drive the switching shaft to rotate. At the same time, the switching shaft can be stably maintained in the current state under the action of the secondary bearing 612.

[0070] Combination Figure 5 and Figure 8 When the main board 51 rotates to a horizontal state and moves toward the reducing station 3, the main bearing 611 meshes with the first rack 45 when the sleeve moves above the reducing station 3 and drives the switching shaft to rotate, thereby causing the diamond-shaped protrusion 62 to rotate and open the grab plate 52 to put down the sleeve. Then the main bearing 611 continues to mesh with the first rack 45, so that the long end of the diamond-shaped protrusion 62 abuts against the grab plate 52, and then the sliding block 44 begins to reset. Since the main bearing 611 is a one-way bearing, it will not drive the switching rod 61 to rotate during the reset process of the sliding block 44, and then the fixed stroke of the main board 51 is used to cooperate to realize the automatic grabbing and lowering of the sleeve. Compared with pneumatic fingers, it can effectively reduce the problems of unstable air pipe connection and air pipe bending or interference caused by the frequent flipping of the mounting plate 41 after the air pipe is connected.

[0071] Embodiment 2 of the present application is: the continuous squeezing state of the tension block 5121 by the compression spring 5122 is used to make the two grab plates 52 always close to each other and have enough force to stably clamp the sleeve. Then, by using the fixed stroke of the main board 51 and the meshing relationship between the main bearing 611 and the first rack 45 and the second rack 15, in conjunction with the one-way bearing property of the main bearing 611, the structure of the diamond-shaped protrusion 62 is used to realize the automatic opening and clamping of the two grab plates 52 at the corresponding positions. Compared with the pneumatic fingers, it can effectively reduce the problems of loosening, bending and interference caused by the air pipe connected to the pneumatic fingers during the long-term flipping of the mounting plate 41.

[0072] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
