Description

Technical Field

[0001] This utility model relates to the field of steel cabinet manufacturing technology, and in particular to an assembly tooling for welding steel cabinets. Background Technology

[0002] In the steel cabinet manufacturing industry, welding assembly fixtures are key equipment for ensuring the structural accuracy of the cabinet frame. Traditional fixtures can generally only perform assembly and welding operations on a single plane frame. The operation method is as follows: first, assemble and weld the various components of the first plane frame, then remove the first plane frame and assemble and weld the various components of the second plane frame; subsequently, assemble the various components of the column frame in sequence, and weld their lower ends to the second plane frame; then place the first plane frame on top of the column frame for welding. This operation method has the following shortcomings: 1. It requires moving the welded first plane frame twice, which not only increases labor intensity but also affects welding efficiency; 2. When welding the column frame, there is a lack of positioning reference points at its upper end, making the column frame prone to skew, affecting the overall frame shape and position quality.

[0003] To address this, we designed an assembly fixture for welding steel cabinets. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model discloses an assembly tooling for welding steel cabinets.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An assembly fixture for welding steel cabinets, comprising:

[0007] The lower positioning component includes a fixing frame, a support leg located at the bottom of the fixing frame, and positioning sleeves located on the outer side of each side wall of the fixing frame; the upper end of the positioning sleeve extends to the top of the fixing frame and is used to position the first planar skeleton body, and a welding space is formed between the positioning sleeve and the corner end of the fixing frame.

[0008] The upper positioning component includes a movable frame and columns disposed on the top surface of each of its side walls; the movable frame is sleeved around the lower positioning component, the upper end of the columns extends to the top of the positioning sleeve and is provided with a positioning block, and the positioning block is equipped with a connector for fixing the second planar skeleton.

[0009] The drive component connects to the movable frame and drives its lifting and lowering, providing assembly space for the column frame.

[0010] Furthermore, the upper end of the positioning sleeve extends to a height that is 2 / 3 to 1 times the height of the first planar skeleton.

[0011] Furthermore, each column corresponds to a positioning sleeve, and the upper end of the column slides through the positioning sleeve.

[0012] Furthermore, the column body is fitted with a buffer sleeve.

[0013] Furthermore, the connector is a magnetic block located on the top surface of the positioning block, which magnetically fixes the second planar skeleton.

[0014] Furthermore, the connector is a locking screw screwed to the positioning block, which fixes the second planar skeleton body by contacting the end face.

[0015] Furthermore, the fixing frame is provided with a connecting horizontal plate in the middle, and the lower plate of the connecting horizontal plate has an upwardly raised cavity in the middle.

[0016] Furthermore, the drive component is a winch, the main body of which is fixed in the middle of the fixed frame, and the winding rope is connected to the middle horizontal plate of the movable frame.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The positioning sleeve of the lower positioning component extends to the top of the fixed frame to achieve the positioning of the first planar frame body; the upper positioning component positions the second planar frame body through the positioning block and connector, and the drive component drives the lifting and lowering to provide assembly space for the column frame body, realize layered assembly and welding, avoid repeated handling and positioning of parts, and improve assembly accuracy and welding efficiency.

[0019] 2. The column slides through the positioning sleeve to form a guide structure, ensuring that the second plane frame does not tilt during the lifting and lowering of the upper positioning component, and ensuring the accuracy of the overall frame welding dimensions.

[0027] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if terms such as "upper", "lower", "front", "rear", "left", "right" indicate orientation or positional relationship, they are only corresponding to the drawings of this application for the convenience of describing the present invention. It should be understood that if terms such as "end", "side", "end portion", "side part", "lateral", "longitudinal", etc. indicate orientation or positional relationship, they are only corresponding to the length and width of the corresponding component. That is, "end" indicates the head and tail area in the length direction of the corresponding component, and "side part" indicates the head and tail area in the width direction of the corresponding component. They are used for the convenience of describing the present invention and do not indicate or imply that the device or element referred to must have a specific orientation.

[0028] Example 1, in conjunction with Appendix Figure 1-2 An assembly fixture for welding steel cabinets includes a lower positioning component 1, an upper positioning component 2, and a driving component 3. The lower positioning component 1 positions various parts of the first planar frame 100 to be welded, and then welding is performed. The upper positioning component 2 positions various parts of the second planar frame 200 to be welded (placed on the top surface of the first planar frame 100), and then welding is performed. The driving component 3 drives the upper positioning component 2 to rise, causing the second planar frame 200 to rise, providing space for assembling the column frame 300. Then, the two ends of the column frame 300 are respectively attached to the first planar frame 100 and the second planar frame 200.

[0029] Furthermore, the lower positioning component 1 includes a fixing frame 11, a support leg 12 disposed at the bottom of the fixing frame 11, and a positioning sleeve 13 disposed on the outer side of each side wall of the fixing frame 11; the upper end of the positioning sleeve 13 extends above the fixing frame 11 for positioning the first planar skeleton body 100, and a welding space is formed between the positioning sleeve 13 and the corner end of the fixing frame 11.

[0030] As needed, the upper extension height of the positioning sleeve 13 is 2 / 3 to 1 times the height of the first planar skeleton 100. This ensures that the first planar skeleton 100 is located below the positioning block 23 after assembly and welding, meaning that when the upper positioning component 2 is driven upward by the driving component 3, it will not affect the position of the first planar skeleton 100.

[0031] In one possible implementation, the fixing frame 11 is a rectangular frame structure, formed by welding channel steel. If necessary, the four corners of the fixing frame 11 are chamfered (not shown in the figure) to allow for welding space.

[0032] In one possible implementation, the support leg 12 has an adjustable foot at its bottom.

[0033] In one possible implementation, the positioning sleeve 13 is a square tube, with its upper end extending to 80% of the height of the first planar skeleton body 100 above the fixing frame 11; the inner diameter of the positioning sleeve 13 is slightly larger than the outer diameter of the column 22, and the distance between it and the corner of the fixing frame 11 is 10-15cm, for the welding gun to operate.

[0034] The upper positioning component 2 includes a movable frame 21 and columns 22 located on the top surface of each of its side walls; the movable frame 21 is sleeved around the lower positioning component 1, and the upper end of the column 22 extends above the positioning sleeve 13 and is provided with a positioning block 23. The positioning block 23 is equipped with a connector 24 for fixing the second planar skeleton 200.

[0035] As needed, the column 22 corresponds one-to-one with the positioning sleeve 13, and the upper end of the column 22 slides through the positioning sleeve 13; that is, the positioning sleeve 13 guides the column 22, and then guides the upper positioning component 2, so as to prevent the second plane frame 200 from being tilted when assembling and welding the column frame 300, which would cause the overall frame size of the first plane frame 100, the second plane frame 200 and the column frame 300 to deviate.

[0036] As needed, to prevent the movable frame 21 from colliding with the positioning sleeve 13 when the drive component 3 drives the upper positioning component 2 to rise, the second planar skeleton 200 is tilted relative to the upper positioning component 2 under the action of inertia; the column 22 is fitted with a buffer sleeve 25 (such as a rubber sleeve or spring).

[0037] In one possible implementation, the movable frame 21 is a rectangular frame and is clearance-fitted with the fixed frame 11.

[0038] In one possible implementation, the column 22 is a square tube smaller than the size of the positioning sleeve 13.

[0039] In this embodiment, the connector 24 is a magnetic block (such as a dial indicator magnetic base or other electromagnetic block) located on the top surface of the positioning block 23, which magnetically fixes the second planar skeleton 200.

[0040] Furthermore, the drive component 3 is a winch, with its main body bolted to the connecting horizontal plate 14 in the middle of the fixed frame 11, and the extended end of the winding rope connected to the middle horizontal plate 26 of the movable frame 21. Due to the flexibility of the winding rope, this configuration allows the upper positioning component 2 to be manually lifted when assembling the column frame 300, ensuring that the column frame 300 is smoothly assembled on the first plane frame 100 and the second plane frame 200.

[0041] Preferably, the fixing frame 11 has a connecting horizontal plate 14 in the middle, and the lower plate of the connecting horizontal plate 14 has an upwardly raised cavity 141 in the middle, and the main body of the winch is installed in the cavity 141.

[0042] Example 2, in conjunction with Appendix Figure 1-2 A steel cabinet welding assembly fixture differs from Embodiment 1 in that: the connector 24 is a locking screw, the positioning block 23 is provided with a threaded hole, and after the locking screw is screwed in, it abuts against the frame and fixes the second plane frame body 200 by contacting the end face.

[0043] It should be noted that: only some / all of the positioning blocks 23 may be equipped with connectors 24, or only some connectors 24 may be used, with the other part of the connectors 24 as a spare. It is only necessary to ensure that when the driving component 3 drives the upper positioning component 2 to rise, the second planar skeleton 200 can stably follow the upper positioning component 2 to rise (the relative position of the second planar skeleton 200 and the upper positioning component 2 will not change).

[0044] It should be noted that the locking screw and the magnetic block can be used together.

[0045] Operating procedures

[0046] Combined with appendix Figure 3-5 The explanation is as follows:

[0047] First, attach each component of the first planar frame 100 to the fixing frame 11 and affix it to the corresponding positioning sleeve 13, ensuring that the ends of the connected components are aligned as much as possible. Then, weld the welding positions. Next, attach each component of the second planar frame 200 to the first planar frame 100 and affix it to the corresponding positioning block 23 (when the connector 24 is a magnetic block, the magnetic block can be used to make each component of the second planar frame 200 affix to the corresponding positioning block 23), ensuring that the ends of the connected components are aligned as much as possible. Then, weld the welding positions. Then, lift the movable frame 21 to a predetermined height using the drive assembly 3 to form the installation space for the column frame 300. Then, place the column frame 300 vertically between the first planar frame 100 and the second planar frame 200 and weld it. Finally, drive the movable frame 21 to reset using the drive assembly 3, at which point the entire frame can be removed.
