Description

Technical Field

[0001] This invention relates to the field of assembly equipment technology, and more specifically to a flange and pipe fitting assembly equipment. Background Technology

[0002] Pipe fittings are the main components in the fields of water supply, drainage, and gas pipelines. Mainstream pipe fittings are assembled with flanges to meet different usage requirements.

[0003] When assembling pipe fittings and flanges, it is necessary to ensure that they are coaxially distributed and that the flange is accurately fitted onto the outside of the pipe fitting in the preset position. The assembly of mainstream pipe fittings and flanges is highly dependent on manual labor, which not only involves many steps and is time-consuming and labor-intensive, but also makes it difficult to ensure the precise positioning of the pipe fittings and flanges, resulting in a reduced yield.

[0004] Based on this, the present invention designs a flange and pipe fitting assembly device to solve the above problems. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a flange and pipe fitting assembly device.

The output end of the rotary pressing cylinder is fixedly connected to the pressure block.

[0015] Compared with the prior art, the beneficial effects of this invention are as follows: First, the pipe fitting is transferred to the pipe fitting positioning mechanism through the standardized pipe fitting feeding mechanism. The pipe fitting positioning mechanism positions the pipe fitting in shape, exposing only the part of the pipe fitting to be assembled. Then, the flange is sent to the pipe fitting opening through the standardized flange feeding mechanism. Subsequently, the second X-axis linear module drives the support frame to move to the left, so that the insert block passes through the flange and is inserted into the inner support of the pipe fitting. The flange is then fitted onto the outside of the pipe fitting along the tapered transition section. Then, the first linear push cylinder pushes the outer sleeve to the left, so that the outer sleeve pushes the flange to the left under the limiting action of the intermediate cylinder until the flange and the step of the pipe fitting are in contact. At this time, the inner support component tightens the part of the inner wall of the pipe fitting corresponding to the flange position, so that the deformation of the pipe fitting engages with the toothed structure of the inner ring surface of the flange. Finally, the inner support component, the outer sleeve and the intermediate cylinder are reset in sequence, and the pipe fitting positioning mechanism releases the finished part, realizing the automated, efficient and high-precision assembly of pipe fittings and flanges, significantly improving assembly efficiency and yield, and ensuring the consistency of finished products.

[0021] In some embodiments, please refer to the accompanying drawings. Figures 1-10 A flange and pipe fitting assembly equipment includes a frame 1 and a standardized pipe fitting feeding mechanism 2, a standardized flange feeding mechanism 3, a step-by-step assembly mechanism 4, and a pipe fitting positioning mechanism 5 mounted on the frame 1.

The two secondary positioning components are installed on the support platform 52 and are located on the front and rear sides of the fixed base 53, respectively. The secondary positioning assembly includes a third Y-axis linear module 54 and a positioning block 55. The third Y-axis linear module 54 is fixedly connected to the support platform 52, and the moving end of the third Y-axis linear module 54 is fixedly connected to the positioning block 55. The positioning blocks 55 of the two secondary positioning assemblies are interlocked, and the near ends of the positioning blocks 55 of the two secondary positioning assemblies are provided with contour grooves that are compatible with the pipe fitting.

[0029] The specific working steps of this invention are as follows: Step 1: The pipe fitting moves directionally along the conveying channel, and under the action of gravity, one end of the pipe fitting droops down; Step 2: The pipe fitting moves from the discharge end of the conveying channel to the positioning seat 213. The rotating pressing cylinder 211 drives the pressing block 212 to swing and align with the positioning seat 213, and then the pressing block 212 moves down. The positioning of the pipe fitting is achieved through the cooperation of the pressing block 212 and the positioning seat 213. Step 3: The first X-axis linear module 221 and the Z-axis linear module 222 work together to drive the air shaft 226 to be inserted into the inside of the pipe. The top block 225 abuts against the end face of the pipe. Then, the air shaft 226 is controlled to expand inward to achieve positioning and clamping of the pipe. Step 4: Move the pipe fitting towards the fixed base 53. During the movement, control the pipe fitting to rotate to a horizontal position using the rotary cylinder 224. Step 5: Place the pipe fitting in the contour groove of the fixed seat 53. The third Y-axis linear modules 54 on both sides control the positioning blocks 55 to push towards the pipe fitting, so that the pipe fitting is clamped and fixed with the cooperation of the fixed seat 53 and the two positioning blocks 55. Only the outer part of the pipe fitting step is exposed. The air shaft 226 then retracts to release the pipe fitting and perform positioning and clamping for the next pipe fitting. Step 6: The flange moves directionally along the material pipe 312. When the material trough 323 and the discharge end of the material pipe 312 are aligned, the flange enters the material trough 323 and is in place. Step 7: The first Y-axis linear module 321 drives the horizontal arm 322 to move forward inside the first limiting plate 324 and the second limiting plate 325, so that the flange in the material trough 323 is coaxially distributed with the exposed pipe, while the side wall of the horizontal arm 322 blocks the discharge end of the material pipe 312. Step 8: Drive the support frame 42 to the left through the second X-axis linear module 41, so that the insert block 45 passes through the flange and is inserted into the inner support of the pipe fitting, and the flange is sleeved on the outside of the pipe fitting along the tapered transition section; Step 9: Push the outer sleeve 44 to the left by the first linear push cylinder 47, so that the outer sleeve 44 pushes the flange to the left under the limiting action of the intermediate cylinder 43 until the flange and the step of the pipe fitting are in contact. Step 10: The inner rod 461 is pushed inward by the second linear push cylinder 466, the spring 465 is compressed, and the support block 462 extends outward along the insert block 45 radially under the cooperation of the driven wedge block 463 and the active wedge block 464, tightening the inner wall of the pipe fitting at the part corresponding to the flange position, so that the deformation of the pipe fitting engages with the toothed structure of the inner ring surface of the flange. Step 11: The output end of the second linear push cylinder 466 is reset, causing the spring 465 to drive the inner rod 461 to reset, which in turn causes the support block 462 to reset and retract into the insert block 45. The outer sleeve 44 and the intermediate cylinder 43 are then reset in sequence. The third Y-axis linear module 54 drives the pipe positioning mechanism 5 to reset, so that the finished part is fully exposed. The second Y-axis linear module 51 drives the support platform 52 to move backward, and the finished part is discharged by the robotic arm.
