Description

Technical Field

[0001] The utility model relates to the technical field of butterfly valve assembly, in particular to a full-automatic butterfly valve assembly machine. Background Art

[0002] The butterfly valve is a common valve used to control the flow of fluids. Its structural feature is a disc-shaped valve disc that rotates within the valve body to open and close the fluid channel. When assembling the butterfly valve, the valve body, valve disc, and sealing ring parts are correctly stacked and pressed together using a pressing mechanism to achieve fully automatic assembly. Currently, the tops of some fully automatic butterfly valve assembly machines are set low, and the position where the butterfly valve is taken and placed is far away from the edge of the assembly machine. As a result, workers need to bend over to take and place the butterfly valve on the assembly machine, so it is easy for their heads to hit the top of the assembly machine. The external structure of the butterfly valve is metal and it is heavy. If you have to bend down and bend over to take and place the butterfly valve on the assembly machine, this design not only fails to take into account the comfort and safety of the workers, but also makes it very inconvenient for the workers to operate. Utility Model Content

[0003] The purpose of the present invention is to address the problem that the tops of some current fully automatic butterfly valve assembly machines are set relatively low, and the position for taking and placing the butterfly valves is far away from the edge of the assembly machine, so that workers need to bend over to take and place the butterfly valves on the assembly machine, so that it is easy for their heads to hit the top of the assembly machine. If they have to lower their heads and bend over to take and place the butterfly valves on the assembly machine, this design not only fails to take into account the comfort and safety of the workers, but also causes great inconvenience to the workers' operation. Therefore, a fully automatic butterfly valve assembly machine is proposed.

[0005] Optionally, the abutment mechanism includes a U-shaped pressing frame fixedly mounted on the piston rod of the cylinder, both ends of the U-shaped pressing frame are fixedly connected to a push plate, the bottom of the push plate is provided with an inclined push surface, and one end of the push plate is fixedly connected to a clamping block.

[0006] Optionally, the driving mechanism includes an assembly card seat designed to slide on the workbench, and the outer wall of the assembly card seat is provided with a pair of driving blocks that are supported by the support plate and drive the assembly card seat to move toward the bottom of the lifting mechanism, and the top of the driving block is provided with an inclined end corresponding to the inclined support surface, and the bottom of the driving block is fixedly connected with a connecting block, and the end of the connecting block away from the driving block is fixedly connected to the outer wall of the assembly card seat.

[0024] Example

[0025] like Figures 1 to 4 As shown, the fully automatic butterfly valve assembly machine proposed in the utility model includes a workbench 1 and a butterfly valve body 9. The workbench 1 is provided with a lifting mechanism for pressing and assembling the butterfly valve body 9, and also includes: the lifting mechanism includes a cylinder 3, and the lifting mechanism also includes a support frame 2 fixedly connected to the upper surface of the workbench 1 to support the operation of the cylinder 3, the bottom end of the piston rod of the cylinder 3 is fixedly connected with an assembly pressing block 31, and the bottom end of the piston rod of the cylinder 3 is fixedly sleeved with a moving mechanism; a driving mechanism that is linked to the moving mechanism and switches is slidably set on the workbench 1 so that the unassembled butterfly valve body 9 is automatically moved to the bottom of the lifting mechanism; a reset mechanism is installed on the upper surface of the workbench 1 so that the driving mechanism automatically rebounds to its original position, and the reset mechanism moves the assembly holder 8 to its original position, thereby repeatedly assembling the butterfly valve body 9.

[0026] Furthermore, the abutting mechanism includes a U-shaped pressing frame 4 fixedly mounted on the piston rod of the cylinder 3, both ends of the U-shaped pressing frame 4 are fixedly connected to a push plate 5, the bottom of the push plate 5 is provided with an inclined push surface 51, and one end of the push plate 5 is fixedly connected to a clamping block 52.

[0027] The driving mechanism includes an assembly card seat 8 that is designed to slide on the workbench 1. The outer wall of the assembly card seat 8 is provided with a pair of driving blocks 7 that are pressed by the push plate 5 and drive the assembly card seat 8 to move toward the bottom of the lifting mechanism. The outer wall of the driving block 7 that contacts the push plate 5 is provided with a rotation groove 71. The internal rotation of the rotation groove 71 is connected to a plurality of rotating rollers 72. The rotating rollers 72 are used to make the push plate 5 contact the driving block 7 more smoothly and avoid the generation of large friction between the driving block 7 and the push plate 5. The top of the driving block 7 is provided with an inclined end corresponding to the inclined push surface 51. The bottom of the driving block 7 is fixedly connected to a connecting block 73. The end of the connecting block 73 away from the driving block 7 is fixedly connected to the outer wall of the assembly card seat 8.

[0028] Furthermore, the reset mechanism includes a U-shaped bracket 6 fixedly connected to the upper surface of the workbench 1. The middle part of the U-shaped bracket 6 is provided with a damping buffer block 63 that presses against the assembly bracket 8. The damping buffer block 63 is a component used to reduce the impact and vibration of mechanical equipment during movement. It is usually made of elastic material or liquid-filled material, which can effectively absorb and dissipate the energy brought by movement, thereby reducing vibration and noise, protecting the equipment and the surrounding environment. Both ends of the U-shaped bracket 6 are provided with a telescopic slot 61, and the interior of the telescopic slot 61 is provided with a reset spring 62. The reset spring 62 is used to move the assembly bracket 8 to press against the damping buffer block 63, and then the butterfly valve body 9 to be assembled can be re-placed on the assembly bracket 8, and finally the butterfly valve body 9 can be repeatedly assembled. One end of the reset spring 62 is fixedly connected to the inner wall of the telescopic slot 61, and the other end of the reset spring 62 is fixedly connected to the corresponding connecting block 73.

[0029] In this embodiment, when a fully automatic butterfly valve assembly machine is required, the stacked butterfly valve bodies 9 are first placed on the assembly base 8 and assembled as shown in FIG. Figure 1 As shown. Then start the cylinder 3 on the upper surface of the support frame 2, and the piston rod of the cylinder 3 drives the U-shaped pressing frame 4 to move downward. Both ends of the U-shaped pressing frame 4 drive the corresponding support plates 5 to move downward, and the inclined support surface 51 at the bottom of the support plate 5 will resist the driving block 7. Then, through the design of the inclined support surface 51 and the top of the driving block 7, the driven block 7 that is resisted drives the connecting block 73 to move toward the lifting mechanism. The pair of connecting blocks 73 drives the assembly seat 8 and the butterfly valve body 9 on the assembly seat 8 to move until the block 52 on the support plate 5 is stuck on the vertical surface of the driving block 7. At this time, Figure 2 As shown, the butterfly valve body 9 on the assembly base 8 is pressed and assembled. When the assembled butterfly valve body 9 needs to be removed from the assembly base 8, it is only necessary to start the cylinder 3 so that the piston rod of the cylinder 3 drives the U-shaped pressing frame 4 and the back plate 5 to return to the original position. Figure 1 At this time, the elastic tension of the return spring 62 causes the pair of connecting blocks 73 to drive the assembly base 8 and the butterfly valve body 9 and the corresponding driving blocks 7 to move toward the U-shaped bracket 6 until the assembly base 8 abuts against the damping buffer block 63 on the U-shaped bracket 6. This allows the assembly base 8 to drive the assembled butterfly valve body 9 to move in front of the staff, thereby avoiding the inconvenience of the workers in taking and placing the butterfly valve body 9 on the assembly base 8.
