Description

Technical Field

[0001] This utility model relates to a welding fixture, and more particularly to a cylindrical filter screen forming welding fixture, belonging to the field of filter screen processing technology. Background Technology

[0002] Welding of humidifier filters is a crucial process in the manufacturing of humidifier equipment. As a core component of the humidifier, the quality of the humidifier filter directly affects the humidification effect and the service life of the equipment, while the welding process is related to the stability and sealing of the filter structure. During the welding process, it is necessary to select an appropriate welding method based on the characteristics of the filter material, such as plastic or metal, such as ultrasonic welding, hot melt welding, or laser welding.

[0003] Existing tooling struggles to achieve comprehensive and stable clamping when fixing cylindrical filter screens. Due to the unique shape of the cylindrical filter screen, the tooling cannot tightly conform to its curved surface. During welding, the filter screen is prone to slight displacement due to external forces or its own stress. Especially at the weld joint, this displacement can cause deviations in the originally precisely aligned joint, resulting in an inability to achieve a tight seal after welding. Therefore, a new tooling for forming and welding cylindrical filter screens is proposed. Utility Model Content

[0004] In view of this, the present invention provides a cylindrical filter screen forming and welding fixture to solve or alleviate one of the technical problems existing in the prior art, and at least provides a beneficial option.

[0006] A first motor is mounted on the top of the bracket. The output shaft of the first motor is fixedly connected to one end of a bidirectional lead screw. A slide is symmetrically threaded onto the outer wall of the bidirectional lead screw. A first clamping plate and a second clamping plate are fixedly connected to the front surfaces of the two slides, respectively. A second motor is mounted on the front surface of the first clamping plate. The output shaft of the second motor is fixedly connected to one end of a threaded rod. A slider is threaded onto the outer wall of the threaded rod. A rotating shaft is mounted on the outer wall of the slider. A pressure roller is rotatably connected to the outer wall of the rotating shaft. A cylindrical filter screen is placed outside the support cylinder. The first motor drives the bidirectional lead screw to rotate, causing the two slides to move relative to each other. The first clamping plate and the second clamping plate clamp the cylindrical filter screen outside the support cylinder to prevent the filter screen from moving during welding, thus enhancing the stability of the welding. The second motor drives the threaded rod to rotate, causing the slider to move. During welding, the pressure roller moves synchronously with the welding head.

A slide 24 is symmetrically threaded onto the outer wall of the bidirectional lead screw 23. A first clamping plate 25 and a second clamping plate 214 are fixedly connected to the front surfaces of the two slides 24, respectively. A second motor 26 is mounted on the front surface of the first clamping plate 25. The output shaft of the second motor 26 is fixedly connected to one end of a threaded rod 27. A slider 28 is threaded onto the outer wall of the threaded rod 27. A rotating shaft 29 is mounted on the outer wall of the slider 28. A pressure roller 210 is rotatably connected to the outer wall of the rotating shaft 29. A cylindrical filter screen is placed outside the support cylinder 213, allowing air to pass through. The first motor 22 drives the bidirectional lead screw 23 to rotate, which in turn drives the two slides 24 to move relative to each other. The first clamping plate 25 and the second clamping plate 214 clamp the cylindrical filter screen outside the support cylinder 213 to prevent the filter screen from moving during the welding process. The second motor 26 drives the threaded rod 27 to rotate, which in turn drives the slider 28 to move. During welding, the pressure roller 210 moves synchronously with the welding head to press the weld joint and prevent the joint from separating and affecting the product quality. The welding head is positioned above the support cylinder 213 and the filter screen during the welding process. The welding head moves along the joint under the action of the drive mechanism to complete the welding work at the filter screen joint.

[0029] In this embodiment, specifically: a sleeve 211 is fixedly connected to the front surface of the bracket 21. The sleeve 211 is used to fix the support cylinder 213. The support cylinder 213 is fixed by the fixing bolt 212 so as to facilitate quick replacement of the support cylinder 213.

[0030] In this embodiment, specifically: the inner wall of the sleeve 211 is fixedly connected to the support cylinder 213 by the fixing bolt 212, and the cylindrical filter screen is placed outside the support cylinder 213.

[0031] In this embodiment, specifically: the support cylinder 213 is disposed between the first clamping plate 25 and the second clamping plate 214, and the first clamping plate 25 and the second clamping plate 214 are used to clamp the cylindrical filter screen outside the support cylinder 213 to prevent the filter screen from moving during the welding process and improve the stability of the filter screen.

[0032] In this embodiment, specifically: the slide table 24 is slidably connected to the front surface of the bracket 21, and the two slide tables 24 move synchronously to facilitate quick clamping and loosening of the cylindrical filter screen.

[0033] In this embodiment, specifically: the slider 28 is slidably connected to the inner wall of the first clamping plate 25, and the movement of the slider 28 causes the pressure roller 210 to move synchronously with the welding head during the welding process.

[0034] In this embodiment, specifically: a support component 10 is provided at the bottom of the fixing component 20, and the support component 10 includes a base 11 and a support leg 12;

[0035] The bottom of the base 11 is symmetrically and fixedly connected with support legs 12, which play a role in stabilizing the support. The bottom of the support legs 12 is provided with anti-slip pads to prevent the tooling from moving.

[0036] In this embodiment, specifically: the bracket 21 is fixedly connected to the top of the base 11, and the bracket 21 is used to support other components of the fixing assembly 20.

[0037] In operation, the present invention involves placing a cylindrical filter screen outside the support cylinder 213. The first motor 22 drives the bidirectional lead screw 23 to rotate, causing the two slides 24 to move relative to each other. The first clamping plate 25 and the second clamping plate 214 clamp the cylindrical filter screen outside the support cylinder 213 to prevent the filter screen from moving during welding, thereby enhancing the stability of welding. During welding, the welding head moves along the joint under the action of the drive mechanism. The second motor 26 drives the threaded rod 27 to rotate, causing the slider 28 to move. During welding, the pressure roller 210 moves synchronously with the welding head, thereby avoiding displacement at the joint during welding and improving the welding quality.
