Description

Technical Field

[0001] This utility model relates to the field of sheet metal technology, and in particular to a tooling for welding embedded parts of metal doors. Background Technology

[0002] Cleanrooms typically feature metal doors made of steel or other materials. Embedded components are generally welded and fixed to the door panel, frame, and other profiles of these metal doors. These embedded components are used to connect to hinges and other structures on the metal door via bolts, thus providing a foundation for the connection of various parts of the metal door. Specifically, the embedded component has a central plate at different planes and welded portions at both ends. When the welded portions are welded to corresponding components, a gap exists between the central plate and the component to prevent that part from being welded as well.

[0003] In practical use, the parts in metal doors used for welding with embedded parts generally have problems such as excessive length, width, or welding position size, which makes it inconvenient to spot weld or completely weld the embedded parts using a welding gun.

[0004] In addition, when using a welding torch to weld embedded parts and related components, the welding position of the embedded parts is prone to deviation due to welding deviation, and the embedded parts may have insufficient welding strength. Utility Model Content This utility model provides a tooling for welding embedded parts of metal doors, which can solve at least one of the above-mentioned technical problems.

[0005] To address the aforementioned technical problems, one or more embodiments of this utility model provide a welding fixture for metal door embedded parts, including a base. One side of the base is fixed to a support, which is used to connect a resistance welding machine. Two movable seats supported by the base are provided on the upper part of the base. A sliding groove extending in a first horizontal direction is provided on the base. The two movable seats can move and be positioned respectively along the first direction to adjust the distance between the two sliding seats.

[0006] Two movable seats are each provided with a boss on one side opposite to each other along the first direction. The bosses are used to support the welded parts at both ends of the embedded part. A vertical positioning post is inserted into the movable seat. The upper end of the positioning post protrudes from the movable seat. The positioning post is used to be inserted into the positioning hole of the embedded part. The positioning post can move and be positioned relative to the movable seat along the first direction.

[0007] The beneficial effects of one or more of the above technical solutions are as follows: In this application, the movable base is provided with a boss, and the distance between two movable bases can be adjusted and fixed to fix and support embedded parts of different lengths between the two movable bases. Furthermore, the structure of the boss facilitates adaptation to the shape of the embedded part, ensuring that both the middle plate and welded portion of the embedded part are supported by the movable base. Simultaneously, the positioning pin can be inserted into the corresponding hole on the embedded part to achieve positioning of the movable base and the embedded part. Moreover, the positioning pin can move along a first direction to accommodate situations where the spacing of corresponding holes differs in different embedded parts.

[0008] When the above-mentioned base, movable seat and positioning column are used, the welding part of the embedded part is made to fit with the side wall of the embedded opening of the door panel or door frame and other components, which makes it easy to use a resistance welding machine to weld and fix the embedded part to the door panel or door frame and other components.

[0009] Based on the tooling used in this device, it is convenient to use the tooling to position the embedded parts, thereby facilitating the positioning of the embedded parts with the door panel or door frame, and making it easy to use the resistance head of the resistance welding machine to press the door panel or door frame, thus achieving the welding and fixing of the embedded parts. Compared with the manual welding method used in the prior art, it can avoid the welding difficulties caused by the narrow size of the parts.

Detailed Implementation

[0011] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0012] like Figures 1-5As shown, one or more embodiments of this utility model provide a welding fixture for metal door embedded parts, including a base 2. One side of the base 2 is fixed to a bracket 1, which is used to connect a resistance welding machine. The upper part of the base 2 is provided with two movable seats 3 supported by the base 2. The base 2 is provided with a sliding groove 201 extending in a first horizontal direction. The two movable seats 3 can move and be positioned in the first direction respectively to adjust the distance between the two sliding seats.

[0013] Two movable seats 3 are respectively provided with bosses 308 on opposite sides along the first direction. The bosses 308 are used to support the welded parts at both ends of the embedded part 4. A vertical positioning post 5 is inserted into the movable seat 3. The upper end of the positioning post 5 protrudes from the movable seat 3. The positioning post 5 is used to be inserted into the positioning hole 304 of the embedded part 4. The positioning post 5 can move and be positioned relative to the movable seat 3 along the first direction.

[0014] In this embodiment, the slide 201 is a T-shaped groove, and a T-shaped slider is installed in the T-shaped groove. Positioning holes 304 are respectively provided on the opposite sides of the two moving seats 3. Locking bolts 303 are inserted into the positioning holes 304. The diameter of the screw head of the locking bolt 303 is larger than the width of the positioning hole 304. The head of the locking bolt 303 passes through the positioning hole 304 to be inserted into the threaded hole of the slider in the slide 201.

[0015] Specifically, when a T-slot and a slider are provided in the slide groove 201, the slider can only slide relative to the slide groove 201 in the first direction. At this time, the slider can be connected to the movable seat 3 through the locking bolt 303 and the aforementioned slider through the locking bolt 303 and the positioning hole 304, thereby realizing the guidance of the movable seat 3 when it slides in the first direction.

[0016] In other embodiments, the T-slot can be replaced with a dovetail slot, and correspondingly, the slider can be a dovetail slider.

[0017] In this embodiment, the positioning hole 304 is an elongated hole extending along the second direction, which is horizontally positioned and perpendicular to the first direction.

[0018] Specifically, the width of the elongated hole is equal to the diameter of the locking bolt 303, thereby limiting the gap between the locking bolt 303 and the elongated hole along the first direction, thus preventing the gap from affecting the positioning accuracy of the movable seat 3 relative to the base 2.

[0019] In this embodiment, the movable seat 3 is provided with an adjustment groove 307 along the first direction, and a positioning post 5 is provided in the adjustment groove 307. The movable seat 3 is provided with a pair of coaxial screw holes on both sides of the adjustment groove 307 along the first direction. A tightening bolt is provided in the screw hole, and the tightening bolt is used to tighten the side of the positioning post 5.

[0020] Specifically, the positioning post 5 here has a circular cross-section. In other embodiments, the positioning post 5 may have an elliptical or square cross-section, or other shapes, which can be determined by those skilled in the art.

[0021] In this embodiment, there are two pairs of screw holes, which are respectively located on the upper and lower parts of the movable seat 3, so that the tightening bolts in the screw holes abut against the upper and lower parts of the positioning column 5 respectively.

[0022] Specifically, the two screw holes at the top are the first screw holes 306, and the two screw holes at the bottom are the second screw holes 305. The bolt in the first screw hole 306 is the first tightening bolt 301, and the bolt in the second screw hole 305 is the second tightening bolt 302.

[0023] Taking the first tightening bolt 301 at the top as an example, the two first tightening bolts 301 respectively abut against the left and right side walls of the positioning post 5 along the first direction, thereby limiting the positioning post 5 along the first direction. To achieve displacement adjustment of the positioning post 5, the tightening degree of the two first tightening bolts 301 used in pairs can be adjusted. Specifically, taking... Figure 1 Taking the positioning pin 5 on the right side as an example, if it needs to be adjusted to the left: rotate the first tightening bolt 301 on the left side outward by a part, and screw the first tightening bolt 301 on the right side into the adjusting groove 307 by a part, thereby providing space for the positioning pin 5 to move to the left.

[0024] In this embodiment, the middle part of the movable seat 3 has a concave portion to divide the adjustment groove 307 into an upper adjustment groove 307 and a lower adjustment groove 307. A pair of screw holes are provided on both sides of the upper adjustment groove 307 and the lower adjustment groove 307.

[0025] This can be understood as the upper and lower parts of the movable seat 3 having a larger width along the second direction, while the middle part of the movable seat 3 has a smaller width along the second direction, thus forming a concave portion. Here, the lower end of the positioning pin 5 protrudes from the upper adjustment groove 307 and extends into the lower adjustment groove 307. Finally, the lower end of the positioning pin 5 is supported by the bottom wall of the lower adjustment groove 307.

[0026] In this embodiment, the lower part of the base 2 has a mounting groove, one end of the bracket 1 is inserted into the mounting groove, and the bracket 1 and the base 2 are connected by bolts; the other end of the bracket 1 is used to connect to the base of the resistance welding machine.

[0027] Specifically, the length of the mounting groove along the first direction is equal to the width of the bracket 1 to be inserted along the first direction. Corresponding bolt holes are provided on the base 2 to facilitate the connection of the bracket 1 and the base 2 using bolts.

[0028] In this embodiment, the upper end of the positioning post 5 is higher than the upper end of the movable seat 3, and the width of the adjusting groove 307 is equal to the diameter of the positioning post 5.

[0029] Working principle: Taking the welding and fixing of the door frame 6 and the embedded part 4 as an example. The end of the bracket 1 away from the base 2 is fixed to the base of the resistance welding machine, so that the base 2 and the movable seat 3 are both below the two welding heads of the resistance welding machine. Adjust the distance between the two movable seats 3 and the position of the positioning column 5 on the movable seat 3 to fit the embedded part 4 to be welded.

[0030] The embedded part 4 is supported and positioned between the two movable seats 3, and the corresponding holes on the embedded part 4 are passed through by the positioning post 5. The embedded opening 601 of the door frame 6 is aligned with the embedded part 4, so that the door frame 6 is moved down to fit against the embedded part 4. At this time, there is a gap between the middle plate of the embedded part 4 and the door frame 6, while the welded parts at both ends of the embedded part 4 are respectively attached to the two sides of the embedded opening 601 on the door frame 6.

[0031] The two welding heads on the resistance welding machine are moved downwards, so that they contact the two sides of the pre-embedded opening 601 on the upper surface of the door frame 6 along the first direction, forming current in the two welding heads, the pre-embedded part 4, and the side wall of the door frame 6, thereby realizing resistance welding. Finally, the two ends of the pre-embedded part 4 are welded to the side of the door frame 6, and the pre-embedded part 4 is fixed at the position of the pre-embedded opening 601.

[0032] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.

[0033] Any aspects of this utility model not described in detail are known to those skilled in the art.
