Description

Technical Field

[0001] The invention relates to the technical field of couplings, and more particularly to an automatic assembly device for coupling diaphragms. Background Art

[0002] The coupling diaphragm is composed of several stacked diaphragms, which are assembled together by screw rings and screws.

[0003] However, the existing coupling diaphragm assembly work usually requires manual pre-assembly of the screw ring and the screw on the assembly hole, which has low work efficiency. It is also necessary to manually rotate the diaphragm to switch the assembly hole, which increases the manual operation time. In addition, the diaphragm cannot be fixed when pressed, and there will be a problem of pressing position offset, which affects the accuracy and quality of the assembly. Summary of the Invention

[0004] The purpose of the present invention is to address the shortcomings of the prior art and provide an automatic assembly device for a coupling diaphragm. By setting a stabilizing component, the fastening plate slides outward to fix the diaphragm during inflation, preventing the diaphragm from shifting in position during assembly, thereby improving the quality and accuracy of assembly. By setting a feeding component a, a feeding component b and a linkage component, the negative pressure suction cup is driven downward when the pressing component is pressed downward. Under the action of the linkage component, the push plate moves upward to realize the simultaneous pressing and feeding operations. In addition, by setting a rotating component, the stabilizing component automatically switches the assembly hole, thereby improving work efficiency and reducing the time of manual operation.

The pressing component 2 is used to drive the feeding component a5 to move downward during the pressing process to place the screw ring 13 on the top of the assembly hole 12, and at the same time drive the feeding component b6 to move upward under the action of the linkage component 8 to insert the screw 14 into the assembly hole 12.

[0033] like Figure 3 As shown, the pressing assembly 2 includes a first cylinder 21 fixedly arranged on the top of the frame 1, a piston rod 22 driven by the first cylinder 21, a pressing plate 23 fixedly arranged below the piston rod 22, and a pressing mold 24 fixedly arranged on the pressing plate 23.

[0035] like Figure 2As shown, the stabilizing component 4 includes a supporting plate 41 fixedly arranged on the rotary chain 31, a supporting column 42 rotatably arranged on the supporting plate 41, an inflatable cylinder 43 arranged in an array along the circumferential direction of the supporting column 42, a sliding rod 44 slidingly arranged in the inflatable cylinder 43, and a fastening plate 45 fixedly arranged on the sliding rod 44. A limiting plate 46 is also fixedly arranged at the bottom of the fastening plate 45. An inflatable tube 47 is connected between the plurality of inflatable cylinders 43. A first sliding groove 48 is also opened on the supporting column 42 along the circumferential direction. The inflatable cylinder 43 is slidably arranged in the first sliding groove 48. The bottom of the inflatable cylinder 43 and the first sliding groove 48 are also fixed. It is fixedly connected with a spring 481, and a square rod 49 is also fixedly provided at the bottom of the support column 42. A limiting rod 491 is also fixedly provided at the lower end of the support column 42. Before use, the diaphragm 11 is manually placed on the limiting plate 46.

When the inflation cylinder 43 is inflated, the slide rod 44 drives the fastening plate 45 to slide outward to fix the diaphragm 11 and prevent the diaphragm 11 from moving. By setting the spring 481, when pressing for assembly, the fastening plate 45 and the diaphragm 11 move downward together, avoiding the problem of the diaphragm 11 tilting when being pressed, affecting the accuracy and quality of assembly.

[0036] like Figure 1 and Figure 3 As shown, the feeding assembly a5 includes a first vibration disk 51, a first discharge pipe 52 fixedly arranged on the first vibration disk 51, a fixed rod 53 fixedly arranged on the piston rod 22, a telescopic rod 54 fixedly arranged on the fixed rod 53, a negative pressure suction cup 55 fixedly arranged at the bottom of the telescopic rod 54, and a negative pressure pipe 56 connected to the negative pressure suction cup 55. By setting the first discharge pipe 52, the screw ring 13 is transported to the bottom of the negative pressure suction cup 55, and the negative pressure suction cup 55 sucks the screw ring 13. Under the action of the negative pressure suction cup 55, the screw ring 13 will not fall on the assembly hole 12, affecting the final assembly quality.

A square groove 76 is provided on the rotating rod 75. By setting the rotating assembly 7, when the stabilizing assembly 4 is transmitted to the top of the rotating assembly 7, the rotating rod 75 moves upward under the drive of the second cylinder 72 so that the square groove 76 cooperates with the square rod 49, and the diaphragm 11 rotates under the drive of the rotating rod 75, thereby realizing the operation of automatically switching the assembly hole 12, reducing the working hours of manual operation and further improving work efficiency.

[0039] like Figure 3 As shown, the linkage assembly 8 includes a first rack 81 fixedly arranged on the fixed rod 53, a second rack 82 fixedly arranged on the lifting rod 64, a connecting rod 83 fixedly arranged on the lifting rod 64, and a gear 84 fixedly arranged on the frame 1. The first rack 81 and the second rack 82 are both engaged with the gear 84. When the piston rod 22 moves downward, the telescopic rod 54 is driven to move downward to place the screw ring 13 on the assembly hole 12. At the same time, the first rack 81 moves downward, and under the engagement of the gear 84, the second rack 82 moves upward, thereby driving the lifting plate 65 to move upward, so that the lifting plate 65 pushes the screw 14 upward to cooperate with the screw ring 13. Through the mechanical structure, the automatic feeding operation is realized, thereby improving work efficiency.

[0040] like Figure 1 As shown, a second sliding groove 9 is further provided on the annular guide rail 32 , and the supporting plate 41 slides in the second sliding groove 9 via a pulley 91 , so that the supporting plate 41 can rotate more stably along the annular guide rail 32 .

[0041] like Figure 7 As shown, the square rod 49 cooperates with the square groove 76. By setting the square rod 49 and the square groove 76, it is prevented that the rotating rod 75 drives the square rod 49 to rotate and slips, thereby affecting the rotation effect.

[0043] like Figure 4 As shown, the components that are the same as or corresponding to those in Example 1 are marked with the corresponding figure marks in Example 1. For the sake of simplicity, only the differences from Example 1 are described below. The difference between Example 2 and Example 1 is that a buffer protection pad is provided on both the negative pressure suction cup 55 and the lifting plate 65.

[0044] Here, this embodiment provides a buffer protection pad on both the negative pressure suction cup 55 and the lifting plate 65, so that when the negative pressure suction cup 55 moves downward and cooperates with the screw ring 13, it plays a buffer role, and when the lifting plate 65 moves upward and cooperates with the screw 14, it plays a buffer role, reducing the possibility of wear of the screw ring 13 and the screw 14, and increasing the service life of the negative pressure suction cup 55, the lifting plate 65, the screw ring 13 and the screw 14.
