Description

Technical Field

[0001] The utility model relates to the field of ceiling lamp production, in particular to a welding positioning device. Background Art

[0002] The frame of the rectangular ceiling light hung in the ceiling of the house is a metal frame with adjacent sides connected vertically. The size is usually 0.5-0.8 meters, and some can be as long as 1.5 meters. The rectangular frame is made of four L-shaped iron strips (or steel strips) welded end to end. During the production process, the worker aligns the two L-shaped iron strips vertically with each other, then places the parts to be connected into the welding rod (welding nozzle) of the spot welding machine for alignment, and then steps on the spot welding machine for spot welding. The two L-shaped iron strips are welded into one, and the adjacent sides are welded continuously to obtain the rectangular frame of the ceiling light. This rectangular frame is then pickled and electrostatically sprayed / painted to obtain a durable ceiling light stand. In the process of using L-shaped iron strips to weld into a rectangular frame, it is necessary to manually align the two L-shaped iron strips vertically with each other, and then place them in a spot welding machine for welding. Due to manual operation, errors are prone to occur when aligning the two L-shaped iron strips vertically, and the welded rectangular frame will have a non-vertical angle, causing the entire frame to be distorted, making it impossible to install the lamp body, and it is also difficult to install it into the opening in the ceiling. In addition, after being installed and used for a period of time, the frame is prone to loosening and falling due to distortion. There are some shortcomings, especially in the production of high-quality ceiling lamps, it is necessary to ensure that the adjacent sides of the frame have a high right angle to avoid distortion and meet the customer's quality standards. Therefore, direct manual alignment welding without auxiliary tools will produce a lot of scrap. If an auxiliary welding positioning tool is designed to increase the right angle between the two L-shaped iron strips during welding, the scrap rate can be reduced, the quality of the product can be improved, and it is more conducive to production. Utility Model Content

[0003] In order to solve the problem that the frame of the ceiling lamp is difficult to be vertically docked and positioned during welding during the manufacturing process, non-vertical errors are easily generated. The right angles between adjacent sides of the frame are not vertical, which causes the entire frame to be distorted, resulting in more waste when producing high-quality ceiling lamps. The present application provides a welding positioning device, which is designed with a vertical frame, positioning grooves, inserts, etc. that cooperate with each other. Workers can efficiently put the L-shaped iron strips into the positioning grooves of the vertical frame for vertical positioning, and then move the vertical frame with the L-shaped iron strips to the welding machine for spot welding, and intersect the two L-shaped iron strips in the vertical frame and weld them vertically to fix them. Then, take out the two intersecting vertical frame side strips, and then put the other end into the positioning grooves of the vertical frame, intersect with the third L-shaped iron strip for vertical positioning, and then weld them. They are welded end to end to form a rectangular frame. During use, the connection angles between adjacent sides can be ensured to be vertical with small errors, avoiding the non-vertical angles of the welded rectangular frame, which causes the entire frame to be distorted, making it impossible to install the lamp body, and it is also difficult to install it in the opening in the ceiling. In addition, after installation and use for a period of time, the frame is easily loosened and falls off due to distortion. The present application can obtain a high-quality frame to better meet customer needs.

[0004] The present invention adopts the following technical scheme: a welding positioning device, including a vertical frame, a positioning groove, and an insert. The vertical frame is provided with two intersecting vertical sides, and vertically intersecting positioning grooves are provided in the vertical sides. The positioning groove is used to place L-shaped iron strips. The intersection of the vertical sides of the vertical frame is provided with an insert that is tightly fitted with the insert body. When the side ends of the two L-shaped iron strips are respectively inserted into the positioning grooves of the vertical frame and contact each other, the two L-shaped iron strips intersect vertically under the positioning action of the positioning grooves. The insert body is located at the vertical intersection and contact point of the two L-shaped iron strips. The spot welding machine can control the welding nozzle to move downward and perform spot welding on the welding spot to weld the two vertically intersecting L-shaped iron strips into one. When the worker moves the vertical frame with two vertically intersecting L-shaped iron strips installed into the spot welding machine, the contacts of the spot welding machine touch the insert body, and when the welding nozzle is aligned with the welding position, the switch of the spot welding machine is stepped on, and the spot welding machine controls the welding nozzle to move downward and weld the welding spot, welding the two vertically intersecting L-shaped iron strips into one, and then takes out the two welded frame edge strips, and then puts the other end of the frame edge strip into the positioning groove of the vertical frame again and touches it vertically with the third L-shaped iron strip, and then welds it, and welds it end to end into a rectangular frame. This can avoid the angle of the welded frame being non-vertical, thereby causing the entire frame to be distorted, making it impossible to install the lamp body and difficult to install it into the opening in the ceiling.

[0005] The lower end of the insert body is provided with a base, the width of the base is greater than the width of the insert body, thereby increasing the bottom area of ​​the insert body. When the vertical frame moves to the spot welding machine, the contacts of the spot welding machine can more easily collide with the base of the insert body for welding.

[0006] The insert body and the base are made of metal copper.

[0007] The upper end of the positioning groove of the vertical frame is provided with a guide opening, which plays a guiding role and increases the opening of the upper end of the positioning groove, making it easier to insert the side end of the L-shaped iron strip into the positioning groove, making it more efficient when placing the L-shaped iron strip.

[0008] The width of the positioning groove in the vertical frame is 0.2MM-0.6MM larger than the width of the L-shaped iron strip, preferably 0.4MM. When the L-shaped iron strip is inserted into the positioning groove, the friction between the L-shaped iron strip and the positioning groove can be reduced, and the L-shaped iron strip can be prevented from loosening in the positioning groove, and the vertical angle of welding can be ensured.

[0009] The two intersecting vertical sides of the vertical frame are respectively provided with a taking-out port. When welding is completed once, the welded L-shaped iron strip can be grabbed from the taking-out port by hand to take out the frame body, and then the adjacent sides are welded in sequence. The taking-out port is provided to facilitate the placement and removal of the L-shaped iron strip, thereby improving the efficiency of the welding process.

[0010] The vertical frame is made of plastic material, preferably any one of nylon and ABS.

[0011] The L-shaped iron strips are then welded together to create a more even fit for the fixture, and the fixture can be easily re-fitted to a desired finish. BRIEF DESCRIPTION OF THE DRAWINGS

The vertical frame 5 is provided with two intersecting vertical sides, and a vertically intersecting positioning groove 6 is provided in the vertical side for placing the side ends of the L-shaped iron sheet strip 4. The vertical edge intersection of the vertical frame 5 is provided with an insert 8 and an insert body 9 that fits tightly. When the side ends of the two L-shaped iron sheet strips 4 are respectively inserted into the positioning groove 6 of the vertical frame 5 and touch each other, the two L-shaped iron sheet strips 4 intersect vertically under the positioning action of the positioning groove 6. The insert body 9 is at the vertical intersection of the two L-shaped iron sheet strips 4. The worker then installs the vertical frame 5 with the two vertically intersecting L-shaped iron sheet strips 4. The frame 5 is moved to the spot welding machine 1, the contact of the spot welding machine 1 collides with the insert body 9, and when the welding nozzle 2 is aligned with the welding position 12, the switch of the spot welding machine 1 is stepped on, and the spot welding machine 1 controls the welding nozzle 2 to move downward and spot weld the welding position 12, and weld the two vertically intersecting L-shaped iron strips 4 into one. Then, the two welded frame side strips are taken out, and then the other end of the frame side strip is put into the positioning groove 6 of the vertical frame 5 again to collide vertically with the third L-shaped iron strip 4, and then welded. The rectangular frame is welded end to end in sequence to avoid the angle of the welded frame being not vertical, thereby causing the entire frame to be distorted, making it impossible to install the lamp body and difficult to install it into the opening in the ceiling.

[0020] A base 10 is provided at the lower end of the insert body 9. The width of the base 10 is greater than the width of the insert body 9, which increases the bottom area of ​​the insert body 9. When the vertical frame 5 moves to the spot welding machine 1, the contacts of the spot welding machine 1 can more easily collide with the base 10 of the insert body 9 and then perform welding.

[0021] The insert body 9 and the base 10 are made of copper.

[0022] A guide opening 7 is provided at the upper end of the positioning groove 6 of the vertical frame 5. The guide opening 7 plays a guiding role and increases the opening at the upper end of the positioning groove 6, making it easier for the side end of the L-shaped iron strip 4 to be inserted into the positioning groove 6, making it more efficient when placing the L-shaped iron strip 4.

[0023] The width of the positioning groove 6 in the vertical frame 5 is 0.2MM-0.6MM larger than the width of the L-shaped iron strip 4, preferably 0.4MM. When the L-shaped iron strip 4 is inserted into the positioning groove 6, the friction between the L-shaped iron strip 4 and the positioning groove 6 can be reduced, and the L-shaped iron strip 4 can be prevented from loosening in the positioning groove 6, and the vertical angle of welding can be ensured.

[0024] The two intersecting vertical sides of the vertical frame 5 are respectively provided with a take-out port 11. When welding is completed once, you can grab the welded L-shaped iron strip 4 from the take-out port 11 and take it out, and then weld the adjacent sides in turn. The take-out port 11 is provided to facilitate the placement and removal of the L-shaped iron strip 4, thereby improving the efficiency of the welding process.

[0025] The vertical frame 5 is made of plastic, preferably any one of nylon and ABS.

Then, the vertical frame 5 with the L-shaped iron strip 4 is moved to the spot welding machine 1. The contact of the spot welding machine 1 collides with the base 10 of the insert body 9. When the welding nozzle 2 is aligned with the welding position 12, the switch of the spot welding machine 1 is stepped on, and the spot welding machine 1 controls the welding nozzle 2 to The lower butt welding position 12 is spot welded to weld the two vertically intersecting L-shaped iron strips 4 into one. After the two L-shaped iron strips 4 are welded, the vertical frame 5 is removed and the welded L-shaped iron strips 4 are grabbed from the take-out port 11 to take out the frame body with both sides welded. Then, any end of the frame body with both sides welded is inserted into the positioning groove 6 and the third L-shaped iron strip 4 is put in to intersect vertically and positioned. Then, welding is performed and the adjacent edges are welded in turn to form the whole frame. During use, the verticality error between adjacent edges can be guaranteed to be small, avoiding the adjacent angles of the welded rectangular frame being not vertical, thereby causing the entire frame to be distorted, making it impossible to install the lamp body and difficult to install it into the opening in the ceiling. A high-quality frame is obtained to better meet customer needs and usage requirements.
