Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to a door frame welding fixture and door frame production equipment. Background Technology

[0002] With the expansion of the customized door and window market, the welding precision of door frames, as a core load-bearing structure, directly affects the flatness and service life of the finished product. Traditional door frame welding fixtures require the welding equipment to stop during the clamping process, resulting in low production efficiency. The fixtures' non-modular structure makes replacing vulnerable parts complex, requiring machine shutdown and disassembly of the entire station, affecting continuous production. Long-term use also leads to irreversible degradation of precision due to wear. Repeated disassembly and assembly of the fixtures also causes cumulative errors in the positioning reference, easily resulting in problems such as diagonal deviation and misalignment of the door frame after welding, requiring manual re-adjustment and increasing the scrap rate. Furthermore, existing door frame welding fixtures are only compatible with standard 90° right-angle door frames and are incompatible with C-shaped channel steel door frames, exhibiting poor adaptability.

[0025] According to a first aspect of the present invention, a door frame welding fixture is provided, which includes a frame 10, a moving component 20, and a clamping component.

[0026] The specific structure of the aforementioned components of the door frame welding fixture according to this embodiment will be described below.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 6 As shown, the frame 10 can be formed as a frame-type support structure, and the bottom of the frame 10 can be provided with feet and / or lockable rollers and other components. The frame 10 has a clamping area and a welding area on both sides in the first direction D1. The clamping area is a working area for the operator to clamp and fix the workpiece 81, and the welding area is a working area for welding equipment (such as a welding robot) to weld the clamped workpiece 81. The clamping area and the welding area are arranged opposite to each other on both sides of the frame 10.

[0028] like Figure 1 , Figure 2 and Figure 6As shown, the moving component 20 is mounted on the frame 10. Specifically, the moving component 20 includes a drive component 21 and a worktable 22. The drive component 21 can be a device such as a motor, cylinder, or motor screw that can drive the worktable 22 to move back and forth. The workbench 22 can be formed as a plate or frame structure. The workbench 22 is provided with a bearing position 221 and a clamping position 222. The workpiece 81 is placed on the bearing position 221, so that the workbench 22 supports the workpiece 81. The driving component 21 drives the workbench 22 to reciprocate along the first direction D1, so that the workpiece 81 can be moved to the welding area after being clamped in the clamping area. In this way, the clamped workpiece 81 can be displaced on the frame 10, which is beneficial to the spatial layout of clamping and welding work in the door frame welding fixture. Multiple sets of moving components 20 are provided. Multiple sets of moving components 20 are arranged along the second direction D2. In this way, the driving component 21 on one set of moving components 20 can move the workbench 22 with the clamped workpiece 81 from the clamping area to the welding area for welding equipment to weld. At this time, at least some of the other moving components 20 can be located in the clamping area for the operator to clamp the workpiece 81, so that welding and clamping operations can be performed simultaneously, thereby improving the production efficiency of the door frame.

[0029] like Figures 1 to 13 As shown, the clamping assembly is installed on the clamping position 222. The clamping assembly can be installed on the clamping position 222 by fasteners such as screws or bolts. The clamping assembly has a clamping part that can abut against the surface of the workpiece 81. The clamping part can move towards or away from the workpiece 81 to clamp or release the workpiece 81, so that the workpiece 81 can be fixed on the worktable 22 for welding, or the workpiece 81 after welding can be removed from the worktable 22, and then the workpiece 81 to be welded can be installed. This achieves quick clamping of the workpiece 81, is convenient to operate, and further improves the production efficiency of the door frame. It should be noted that the workpiece 81 after welding can be removed in the welding area or the clamping area, or a disassembly area for removing the workpiece 81 can be set between the welding area and the clamping area.

[0030] In a preferred embodiment, the first direction D1 is a horizontal direction, and the second direction D2 is a vertical direction perpendicular to the first direction D1, so that the clamping area and the welding area are located on both sides of the frame 10 in the horizontal direction, and multiple sets of moving components 20 are arranged in the vertical direction. This is beneficial for leaving working space for operators and welding equipment, and can also effectively compress the site space and increase the utilization rate of the site.

[0031] In this embodiment, as Figures 2 to 5 As shown, workpiece 81 is a part of the door frame structure. It is necessary to weld the fitting 82 onto the main body of workpiece 81. The main body of workpiece 81 is formed into a strip structure extending along the third direction D3.

[0032] Preferably, the first direction D1, the second direction D2, and the third direction D3 are arranged perpendicularly to each other. Furthermore, in this embodiment, as Figure 1 and Figure 11 As shown, the clamping assembly includes a first positioning component 30, which is disposed at one end of the workpiece 81 in the third direction D3 and is used to fix one end of the workpiece 81 in the third direction D3. Specifically, the first positioning component 30 includes a first fixed support 31, a first flip support 32, and a first clamping part 33. The first fixed support 31 is mounted on the clamping position 222. The first flip support 32 is rotatably connected to the first fixed support 31 and the axis of rotation extends along the first direction D1. The first clamping part 33 is disposed on the first flip support 32 and can rotate with the first flip support 32 in a direction closer to or farther from the workpiece 81. Specifically, when the first clamping part 33 rotates with the first flip support 32, it can be lifted upward or pressed downward. The first positioning component 30 can be a tooling clamping component such as a quick-release toggle clamp, a hydraulic clamping element, or a pneumatic clamping element.

[0033] Furthermore, in this embodiment, as Figure 1 , Figures 7 to 10 As shown, the clamping assembly includes a second positioning component 40, which is disposed at the other end of the workpiece 81 in the third direction D3. This allows the first positioning component 30 and the second positioning component 40 to clamp and position the two ends of the workpiece 81 in the third direction D3, thereby fixing the position of the workpiece 81 on the worktable 22. Specifically, the second positioning component 40 includes a second fixed support 41, a rotating support 42, and a second clamping part 43. The second fixed support 41 can be fixed relative to the worktable 22. A protrusion 411 extending along the second direction D2 is formed on the second fixed support 41. The protrusion 411 can be a cylindrical structure with its axis extending along the second direction D2, allowing the rotating support 42 to rotate around the protruding axis. The rotating support 42 has a sliding hole for the protrusion 411 to extend into. The sliding hole can be a through hole structure, so that the rotating support 42 can rotate around the protrusion 411 and slide back and forth along the length of the protrusion 411. The second clamping part 43 is disposed on the rotating support 42 and can rotate and / or slide with the rotating support 42 toward the workpiece 81. Thus, when it is necessary to clamp the workpiece 81, the rotating support 42 can be rotated until the second clamping part 43 is above the workpiece 81, and then the rotating support 42 can be driven to slide on the protrusion 411, so that the second clamping part 43 moves toward the workpiece 81 until the second clamping part 43 is in contact with the workpiece 81, so as to achieve the clamping and positioning of the workpiece 81.

[0034] Similarly, when it is necessary to release the workpiece 81, the rotating support 42 is first driven to slide on the protrusion 411, so that the second clamping part 43 moves away from the workpiece 81. Then, the rotating support 42 is driven to rotate around the protrusion 411 to move the second clamping part 43 away, so that it no longer obstructs the workpiece 81 from being removed from the worktable 22, thus meeting the requirement of removing the welded workpiece 81.

[0035] In a preferred embodiment, such as Figures 7 to 10 As shown, the second positioning component 40 further includes: a first adjusting rail 44 and a first sliding platform 45. The first adjusting rail 44 is installed at the clamping position 222 and is formed as a strip structure extending along the third direction D3. The first adjusting rail 44 is provided with a plurality of first adjusting holes 441 arranged along the third direction D3. The first sliding platform 45 is installed on the first adjusting rail 44 and is formed as a plate structure. A second fixed support 41 is disposed above the first sliding platform 45, so that the second fixed support 41 can move relative to the first adjusting rail 44 together with the first sliding platform 45. The first sliding platform 45 is provided with different first adjusting holes 441 that can extend into it. The first fixing pin of 41 is used to adjust the distance between the first positioning component 30 and the second positioning component 40, thereby improving the adaptability of the welding fixture. This allows workpieces 81 of different sizes to be clamped and fixed without disassembling the first positioning component 30 and / or the second positioning component 40, meeting the positioning and clamping requirements of workpiece 81 in the third direction D3, improving clamping efficiency, and avoiding the increase of cumulative error of positioning reference due to repeated disassembly and assembly. It also improves the situation that door frame diagonal deviation and joint misalignment are prone to occur after welding, eliminating the need for manual secondary adjustment, eliminating assembly gaps and human error accumulation, and reducing the scrap rate of workpiece 81 to a certain extent. Furthermore, in this embodiment, as Figures 7 to 10 As shown, the second positioning component 40 also includes a second sliding platform 46 and a locking member 47. The second sliding platform 46 is formed as a plate structure and is installed on the sliding track 451 of the first sliding platform 45, so that the second sliding platform 46 can slide towards or away from the workpiece 81. The second fixed support 41 is fixed to the top of the second sliding platform 46. Thus, when the distance between the first positioning component 30 and the second positioning component 40 in the third direction D3 is adjusted, in order to avoid interference when the workpiece 81 is placed in the bearing position 221, the second sliding platform 46 can be driven to move along the sliding track 451 away from the first positioning component 30, thereby increasing the material feeding space, facilitating manual material feeding, and improving feeding efficiency.

[0036] In this embodiment, the locking member 47 can be a tooling clamping component such as a quick-release toggle clamp, a hydraulic clamping element, or a pneumatic clamping element. The locking member 47 is installed on the first sliding platform 45 to fix the position of the second sliding platform 46 on the first sliding platform 45, thereby fixing the position of the second sliding platform 46 relative to the first sliding platform 45 after the workpiece 81 is placed, and preventing the second sliding platform 46 from sliding on the sliding track 451.

[0037] Furthermore, in this embodiment, as Figures 7 to 10 As shown, a first scale 442 is provided on the first adjustment track 44, and the first scale 442 has scale markings arranged along the third direction D3; a first pointer 452 is provided on the first sliding platform 45, and the first pointer 452 points to the scale markings on the first scale 442. In this way, the first sliding platform 45 can be quickly adjusted to the position corresponding to the first adjustment track 44 according to the specifications of the workpiece 81, and has good adjustment accuracy. In this embodiment, as Figure 13 As shown, the clamping assembly also includes a first clamping assembly 50. In the third direction D3, the first clamping assembly 50 is disposed between the first positioning assembly 30 and the second positioning assembly 40 to improve the clamping reliability of the workpiece 81. Specifically, the first clamping assembly 50 includes a third fixed support 51, a second flipping support 52, and a third clamping part 53. The third fixed support 51 is mounted on the clamping position 222. The second flipping support 52 is rotatably connected to the third fixed support 51, and its rotation axis extends along the third direction D3. The third clamping part 53 is disposed on the second flipping support 52 and can rotate with the second flipping support 52 in a direction closer to or further away from the workpiece 81. Specifically, the third clamping part 53 is lifted upwards or pressed downwards as the second flipping support 52 rotates. The first clamping assembly 50 can employ tooling clamping components such as quick-release toggle clamps, hydraulic clamping elements, or pneumatic clamping elements.

[0038] It should be noted that the number of the first clamping components 50 can be set to one or more groups according to actual needs. When the first clamping components 50 are set to multiple groups, the multiple groups of first clamping components 50 are arranged at intervals along the third direction D3.

[0039] In this embodiment, as Figure 12 As shown, the clamping assembly also includes a second clamping assembly 60; on the third direction D3, the second clamping assembly 60 is disposed between the first positioning assembly 30 and the second positioning assembly 40 to improve the clamping reliability of the workpiece 81; the difference between the second clamping assembly 60 and the first clamping assembly 50 is that the position of some components in the second clamping assembly 60 on the third direction D3 is adjustable, thus meeting different clamping position requirements and improving the adaptability of the door frame welding fixture.

[0040] Specifically, the second clamping assembly 60 includes a second adjusting rail 61, a third sliding platform 62, a fourth fixed support 63, a third flipping support 64, and a fourth clamping part 65. The second adjusting rail 61 is mounted on the clamping position 222 and extends along the third direction D3. The second adjusting rail 61 is provided with a second scale 611 and a plurality of second adjusting holes arranged along the third direction D3. The second scale 611 has scale markings arranged along the third direction D3. The structure of the second adjusting rail 61 can be the same as that of the first adjusting rail 44 as described above.

[0041] like Figure 12 As shown, the third sliding platform 62 is mounted on the second adjusting rail 61. Specifically, the third sliding platform 62 is provided with a second fixing pin that can extend into different second adjusting holes to adjust the distance between the third sliding platform 62 and the first positioning component 30 and / or the second positioning component 40, thereby improving the adaptability of the welding fixture and meeting different clamping requirements. The third sliding platform 62 is also provided with a second pointer 621 pointing to the scale markings on the second scale 611, so that the third sliding platform 62 can be quickly adjusted to the position corresponding to the second adjusting rail 61 according to the clamping position requirements, and has good adjustment accuracy.

[0042] like Figure 12 As shown, the fourth fixed support 63 is mounted on the third sliding platform 62; the third tilting support 64 is rotatably connected to the fourth fixed support 63 and the axis of rotation extends along the third direction D3; the fourth clamping part 65 is disposed on the third tilting support 64 and can rotate with the third tilting support 64 toward or away from the workpiece 81. The fourth fixed support 63, the third tilting support 64 and the fourth clamping part 65 in the second clamping assembly 60 may have the same structure as the first clamping assembly 50 as described above.

[0043] In this embodiment, the number of workpieces 81 clamped on the same worktable 22 each time can be one or more. When the number of workpieces 81 clamped on the worktable 22 is multiple, the number of the first clamping part 33, the second clamping part 43, the third clamping part 53 and the fourth clamping part 65 on each clamping assembly are set to correspond one-to-one with the number of workpieces 81, so as to meet the clamping requirements of all workpieces 81 and ensure that all workpieces 81 have the same clamping effect.

[0044] In one alternative implementation, such as Figures 2 to 5 As shown, the surface of workpiece 81 has grooves, forming a C-shaped cross-section to create a C-shaped channel steel door frame; as Figures 7 to 11As shown, the first clamping part 33 and the second clamping part 43, as described above, have a base plate that contacts the upper surface of the workpiece 81 and side plates on both sides disposed on the base plate in the first direction D1. This restricts the position of the workpiece 81 in the first direction D1 and improves the positioning accuracy of the workpiece 81. Figure 12 and Figure 13 As shown, the third clamping part 53 and the fourth clamping part 65 can be formed into a block structure.

[0045] In this embodiment, as Figure 12 and Figure 13 As shown, at least part of the bearing position 221 can be formed as a groove structure to provide a reference for placing the workpiece 81 on the worktable 22 and improve the feeding efficiency.

[0046] In addition, such as Figures 7 to 13 As shown, the clamping assembly is provided with a handle 70. Specifically, the handle 70 can be provided on the first flip support 32, the rotating support 42, the second flip support 52 and the third flip support 64 as described above, or on the locking member 47.
