Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of welding fixtures, and more specifically to a profile welding assembly fixture. Background Technology
[0002] After the profiles are processed into the corresponding shapes by the roller press, they also need to be welded by welding equipment. The profiles have different cross-sectional shapes according to the design requirements, such as E-shape or G-shape. Before welding these profiles, the welding machine needs to effectively fix them with appropriate fixtures.
[0003] However, considering that different specifications of profiles have different shapes and dimensions, it would obviously be costly to develop separate fixtures for each type of profile. Therefore, there is an urgent need for a versatile and easy-to-adjust combination fixture. Utility Model Content
[0004] The purpose of this invention is to solve the problem that developing separate fixtures for different profiles would obviously lead to high costs in the existing technology, and to propose a combination fixture that is versatile and easy to adjust.
[0005] To address the aforementioned problems, this utility model provides a profile welding assembly fixture, comprising a base and a vertical positioning component. The vertical positioning component includes a first guide rail, a first adjusting rod, an adjusting sleeve, and two first slides. The first guide rail is horizontally disposed on the base. The base has a first threaded hole with its axis parallel to the first guide rail. The adjusting sleeve is screwed into the first threaded hole. The first adjusting rod is rotatably connected to the inner hole of the adjusting sleeve and is axially fixed relative to the adjusting sleeve. The first adjusting rod includes an adjusting section extending out of the adjusting sleeve. The adjusting section of the first adjusting rod has a first threaded section and a second threaded section in opposite directions. The two first slides are slidably connected to the first guide rail and are screwed into the first threaded section and the second threaded section, respectively. The two first slides are provided with first pressing members for abutting against the workpiece.
[0006] Compared with the prior art, the above solution achieves the contact and positioning of the workpiece through the first pressing members on the two first slides. At the same time, if the first adjusting rod is rotated in the forward direction, the first and second slides will move closer to each other because the first and second threaded sections are set in opposite directions; if the first adjusting rod is rotated in the reverse direction, the first and second slides will move away from each other; if the adjusting sleeve is rotated, the adjusting sleeve will move laterally relative to the first threaded hole, thereby causing the first adjusting rod, the first slide, and the second slide to move relative to the base. Thus, not only can the distance between the two first pressing members be adjusted, but the position of the two first pressing members can also be adjusted simultaneously. The adjustment has a high degree of freedom, and it can be adapted to profile workpieces of different shapes and sizes. It has good versatility and is simple and convenient to adjust.
[0007] In an improved embodiment, the first slide is provided with a first receiving shaft along the vertical direction, and the first pressing element is a pressure roller rotatably sleeved on the first receiving shaft. The first pressing element is a rotatable pressure roller with its axis along the vertical direction, which can abut and limit the side of the workpiece. During the transport of the workpiece, the pressure roller and the workpiece have rolling friction, resulting in low resistance and no damage to the workpiece.
[0008] In an improved embodiment, the lower diameter of the first pressing member is increased to form a circular boss, thereby supporting the lower side of the workpiece through the circular boss.
[0009] In an improved embodiment, the vertical positioning component further includes a first bracket and a limiting roller. The first bracket includes a receiving part connected to the upper end of the first receiving shaft and a limiting roller rotatable about the vertical axis. The limiting roller can extend into the interior of profiles with irregular cross-sections, such as E-shaped or G-shaped profiles, and abut and limit the corresponding position for subsequent welding operations.
[0010] In an improved embodiment, the receiving portion of the first bracket is provided with a mounting groove and a fastening pin extending into the mounting groove. The upper end of the first receiving shaft is rotatably inserted into the mounting groove. The fastening pin is used to abut against the first receiving shaft to fix the first receiving shaft relative to the mounting groove. Thus, when the fastening pin is loosened, the first bracket and the receiving portion can rotate around the first receiving shaft to adjust the angle. After adjustment, the fastening pin is reattached to the first receiving shaft to fix the first receiving shaft relative to the mounting groove. This structure enables the position of the limiting roller to be adjustable, further improving the degree of adjustment freedom.
[0011] In an improved embodiment, the adjusting section of the first adjusting rod is located on one side of the adjusting sleeve, and the first adjusting rod further includes an operating section extending to the other side of the adjusting sleeve, so that the user can rotate the first adjusting rod more conveniently through the operating section.
[0012] In an improved embodiment, a lateral positioning component is further included. The lateral positioning component comprises a second guide rail, a second adjusting rod, and a second slide. The second guide rail is vertically disposed on the base, and the second slide is slidably connected to the second guide rail. The base is provided with a second threaded hole with its axis parallel to the second guide rail. The second adjusting rod is provided with an external threaded section screwed into the second threaded hole and a transition end rotatably connected to the second slide. The second slide is provided with a second pressing member for abutting against the workpiece. Thus, by rotating the second adjusting rod, the second adjusting rod will undergo vertical displacement relative to the second threaded hole, thereby causing the second slide and the second pressing member to undergo vertical displacement, realizing the abutment of the second pressing member against the upper and / or lower sides of profiles of different specifications and sizes.
[0013] In an improved embodiment, the second slide table is provided with a second receiving shaft along the transverse direction, and the second pressing element is a pressure roller rotatably sleeved on the second receiving shaft. The second pressing element is a rotatable pressure roller with its axis along the transverse direction, which can abut and limit the upper or lower side of the workpiece. During the transport of the workpiece, the pressure roller and the workpiece have rolling friction, resulting in low resistance and no damage to the workpiece. Attached Figure Description

[0023] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0024] Please see Figures 1-4 An embodiment of this utility model provides a profile welding assembly fixture, including a base 1 and a vertical positioning component. The vertical positioning component includes a first guide rail 21, a first adjusting rod 22, an adjusting sleeve 23, and two first slides 24. The first guide rail 21 is arranged laterally on the base 1. The base 1 has a first screw hole 11 with its axis parallel to the first guide rail 21. The adjusting sleeve 23 is screwed into the first screw hole 11. The first adjusting rod 22 is rotatably connected to the inner hole of the adjusting sleeve 23 and is axially fixed relative to the adjusting sleeve 23. The first adjusting rod 22 includes an adjusting section 221 extending out of the adjusting sleeve 23. The adjusting section 221 of the first adjusting rod 22 has a first threaded section 221a and a second threaded section 221b in opposite directions. The two first slides 24 are slidably connected to the first guide rail 21 and are screwed into the first threaded section 221a and the second threaded section 221b, respectively. The two first slides 24 are provided with first pressing members 25 for abutting against the workpiece.
[0025] Compared with the prior art, the above solution achieves the contact and positioning of the workpiece through the first pressing member 25 on the two first slides 24. At the same time, if the first adjusting rod 22 is rotated in the forward direction, the first threaded section 221a and the second threaded section 221b are arranged in opposite directions, so the first slide 24 and the second slide 33 will move closer to each other; if the first adjusting rod 22 is rotated in the reverse direction, the first slide 24 and the second slide 33 will move away from each other; if the adjusting screw sleeve 23 is rotated, the adjusting screw sleeve 23 will move laterally relative to the first screw hole 11, thereby causing the first adjusting rod 22, the first slide 24 and the second slide 33 to move relative to the base 1. Thus, not only can the distance between the two first pressing members 25 be adjusted, but the position of the two first pressing members 25 can also be adjusted simultaneously. The adjustment has a high degree of freedom, and it can be adapted to profile workpieces of different shapes and sizes. It has good versatility and is simple and convenient to adjust.
[0026] In this embodiment, with Figure 1Based on this, the first guide rail 21 is arranged in the left-right direction, and two first slides 24 are slidably connected to the left and right sides of the first guide rail 21, respectively. The position between the two first slides 24 is used for the workpiece to pass through. The first slide 24 is provided with a first receiving shaft 241 in the vertical direction, and the first pressing member 25 is a pressure roller rotatably sleeved on the first receiving shaft 241. The first pressing member 25 is a rotatable pressure roller with its axis in the vertical direction, which can abut and limit the left and right sides of the workpiece. During the transport of the workpiece, the pressure roller and the workpiece have rolling friction, resulting in low resistance and no damage to the workpiece.
[0027] Furthermore, the lower diameter of the first pressing member 25 is increased to form a circular boss 251, thereby supporting the lower side of the workpiece through the circular boss 251.
[0028] As an improvement to this embodiment, the vertical positioning component also includes a first bracket 26 and a limiting roller 27. The first bracket 26 includes a receiving part connected to the upper end of the first receiving shaft 241 and a rotatable limiting roller 27 with the vertical axis as the axis. The limiting roller 27 can extend into the interior of profiles with irregular cross sections such as E-shaped or G-shaped profiles and abut and limit the corresponding position for subsequent welding operations.
[0029] Furthermore, the receiving portion of the first bracket 26 is provided with a mounting groove 261 and a fastening pin 262 extending into the mounting groove 261. The upper end of the first receiving shaft 241 is rotatably inserted into the mounting groove 261. The fastening pin 262 is used to abut against the first receiving shaft 241 to fix the first receiving shaft 241 relative to the mounting groove 261. Thus, when the fastening pin 262 is loosened, the first bracket 26 and the receiving portion can rotate around the first receiving shaft 241 to adjust the angle. After adjustment, the fastening pin 262 is re-abutted against the first receiving shaft 241 to fix the first receiving shaft 241 relative to the mounting groove 261. This structure enables the position of the limiting roller 27 to be adjustable, further improving the degree of adjustment freedom. The fastening pin 262 can be a bolt or other fastening parts commonly used in the prior art, such as elastic pins, as long as it can achieve the abutment and fixation of the first receiving shaft 241.
[0030] In this embodiment, the adjustment section 221 of the first adjustment rod 22 is located on one side of the adjustment sleeve 23. The first adjustment rod 22 also includes an operation section 222 extending out to the other side of the adjustment sleeve 23, so that the user can rotate the first adjustment rod 22 more conveniently through the operation section 222.
[0031] As an extension of this embodiment, a lateral positioning component is also included. The lateral positioning component includes a second guide rail 31, a second adjusting rod 32, and a second slide 33. The second guide rail 31 is vertically disposed on the base 1, and the second slide 33 is slidably connected to the second guide rail 31. The base 1 is provided with a second screw hole 12 with its axis parallel to the second guide rail 31. The second adjusting rod 32 is provided with an external thread section screwed to the second screw hole 12 and a transition end rotatably connected to the second slide 33. The second slide 33 is provided with a second pressing member 34 for abutting against the workpiece. Thus, by rotating the second adjusting rod 32, the second adjusting rod 32 will undergo vertical displacement relative to the second screw hole 12, thereby driving the second slide 33 and the second pressing member 34 to undergo vertical displacement, realizing the abutment of the second pressing member 34 against the upper and / or lower sides of profiles of different specifications and sizes.
[0032] More specifically, the second slide table 33 is provided with a second receiving shaft 331 along the transverse direction, and the second pressing member 34 is a pressure roller rotatably sleeved on the second receiving shaft 331. The second pressing member 34 is a rotatable pressure roller with its axis along the transverse direction, which can abut and limit the upper or lower side of the workpiece. During the transport of the workpiece, the pressure roller and the workpiece are subjected to rolling friction, resulting in low resistance and no damage to the workpiece.
[0033] It should be noted that in the description of this application, the terms "inner" and "outer," etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, or be constructed and operated in a specific orientation.
