Description

Technical Field

[0001] This utility model belongs to the field of corrugated pipe weld grinding technology, and specifically relates to a corrugated pipe weld grinding mechanism. Background Technology

[0002] Aluminum alloy welded joints often suffer from three main problems: porosity, hot cracking, and softening of the heat-affected zone. Improper grinding of the weld joint area can increase defects such as porosity, hot cracking, slag inclusions, incomplete penetration, and incomplete fusion, leading to high stress concentration at the weld joint and ultimately causing fatigue failure of the weld. Therefore, to avoid or reduce welding defects such as porosity at the start and end of the weld, weld bead porosity, and cracks, grinding must be performed along the weld direction, ensuring a consistent grinding texture and a surface free of sharp edges.

[0003] Most common bellows clamping mechanisms adopt a two-point contact type. The two-point contact type has a simple structure, but its load capacity is weak and its stability is poor. Due to the small contact area between the two parts, the clamping effect is not ideal.

The terms "install," "connect," "join," and "fix" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] like Figure 1-4 As shown, this embodiment provides a corrugated pipe weld grinding mechanism, including a frame 10 and a placement platform 30 disposed on the frame 10, with grinding tools 20 for grinding the corrugated pipe welds disposed on both sides of the placement platform 30. The placement platform 30 located below the grinder 20 is provided with a mechanical claw clamping component for clamping the bellows laterally, and clamping adjustment components for clamping the bellows longitudinally are provided on both sides of the mechanical claw clamping component.

[0021] Please see Figure 1-5 As shown, the mechanical gripper includes a mechanical gripper end 401 with a built-in drive system, and the mechanical gripper end 401 passes through the mechanical gripper mounting base 405 and is equipped with a mechanical gripper 402 for gripping the bellows. The connection between the mechanical gripper and the mechanical gripper end is prior art and will not be described in detail here.

[0022] In practical applications, most common bellows clamping mechanisms employ a two-point contact design. While simple in structure, this design suffers from weak load capacity and poor stability. Furthermore, the small contact area between the two points results in an unsatisfactory clamping effect. For solutions to these technical problems, please refer to [link to relevant documentation]. Figure 1-5As shown, the mechanical claw 402 also includes a fingertip 403, and a barrier 404 is attached to the inner wall of the fingertip 403. The surface of the barrier 404 is provided with protrusions that match the texture of the outer wall of the corrugated pipe, thereby increasing the contact area. The surface of the barrier 404 is coated with a polyurethane coating.

[0023] In this embodiment, by providing protrusions on the surface of the barrier 404 that match the texture of the outer wall of the bellows, and by spraying a polyurethane coating on the surface of the barrier 404, the contact area is increased and the coefficient of friction is improved. This replaces the traditional two-point contact mechanical gripper, reducing the clamping pressure fluctuation by 60% and effectively preventing the bellows from falling off.

[0024] Furthermore, the clamping adjustment component is fixedly installed on the side end face of the fixing seat 50 by fastening screws, and the fixing seat 50 is installed on the placement platform 30 by welding or fastening screws.

[0025] Furthermore, the clamping adjustment component includes a clamping seat 601, which is mounted on the side end face of the fixing seat 50 by fastening screws. The clamping seat 601 is provided with a clamping tube 602 inside, and the clamping tube 602 has a snap-fit ​​groove for the insertion end 607 to extend into and engage. The insertion end 607 is integrally formed with the clamping seat 601.

[0026] In practical applications, in order to improve the fixed connection between the clamping seat and the clamping tube, a fastening screw can be added to the plug end to improve the fixed connection between the clamping seat and the clamping tube. During installation, the fastening screw can be passed through the threaded holes of the clamping seat and the clamping tube to make a threaded connection.

[0027] Furthermore, a stepped cavity is formed inside the clamping tube 602, and a clamping member 608 is welded to the bottom end face of the cavity. The clamping member 608 is made of elastic material. At least one set of grooves 609 are formed on the clamping member 608, and the grooves 609 are thicker at both ends and thinner in the middle. The transition between the thick sections at both ends and the thin section in the middle forms a "quasi-wedge" structure, which can generate a self-locking force under vibration conditions, so that the bellows can be inserted into the clamping member 608 and can be locked better to prevent the clamped part (such as the bellows) from slipping.

[0028] Furthermore, a second tapered end 606 is provided on the top end face of the clamping member 608, which is away from the bottom end face of the clamping member 608.

[0029] Furthermore, a first threaded end 605 is provided inside the clamping tube 602 away from the second tapered end 606, and the first threaded end 605 cooperates with the second threaded end 606 provided on the outer wall of the adjusting member 604 to perform threaded engagement. The adjusting member 604 can be made of materials such as stainless steel.

[0030] In this embodiment, by rotating the adjusting member 604, the adjusting member 604 can be moved toward the second conical end 606.

[0031] Furthermore, the bottom inner wall of the adjusting member 604 is provided with a first conical end 6041, and the inner wall of the first conical end 6041 is in close contact with the outer wall of the second conical end 6081.

[0032] In this embodiment, the bellows to be clamped is inserted into the clamping cavity 603. Then, by rotating the adjusting member 604 in the forward direction, the engagement of the second threaded end 606 and the first threaded end 605 of the adjusting member 604 converts the rotational motion into linear displacement, driving the adjusting member 604 to move towards the second conical end. This causes the first conical end to continuously press against the second conical end until the first conical end 6041 and the second conical end are completely in contact. At this time, the clamping member 608 is radially contracted by the pressure of the conical surface, thereby fixing the inserted bellows.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not restrictive. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solution of this utility model do not depart from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
