Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically a welding positioning device. Background Technology

[0002] Welding is an important part of the machining field. Currently, when welding steel components, workers usually need to manually support them or use special fixtures for positioning. However, manual support has poor stability and safety.

[0003] However, existing tools for clamping and positioning profiles can only weld profiles of a specified shape. For profiles with different cross-sections such as circles, squares, or polygons, specific positioning fixtures are required for positioning. This requires a large amount of raw materials to produce the positioning fixtures, resulting in a waste of resources. Furthermore, existing fixtures with replaceable positioning mechanisms require workers to use tools to disassemble and replace the positioning mechanism, which is inconvenient and further affects welding efficiency. Therefore, a welding positioning device is proposed. Utility Model Content

[0007] Preferably, the snap-fit ​​assembly includes a Y-shaped frame, which is symmetrically arranged inside the movable groove opened on the inner wall of the socket, and is snapped into the annular groove on the outer arc surface of the replaceable base. The inner walls of the two sets of Y-shaped frames opposite each other are provided with snap-fit ​​blocks for inserting into the snap-fit ​​grooves located inside the inner wall of the replaceable base. It also includes a drive module for driving the Y-frame to fix the replaceable base in place.

[0008] Preferably, the drive module includes a gear and an L-shaped frame. The interior of the fixed base has mounting slots extending through both sides of the moving slot. The L-shaped frame is connected to the mounting slots via connecting springs. The gear is rotatably disposed between the L-shaped frame and the Y-shaped frame, and meshes with toothed plates disposed on the side walls opposite to the L-shaped frame and the Y-shaped frame.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-5 This utility model provides a technical solution: A welding positioning device, It includes an operating table 1, a fixed frame 2, and a movable frame 3. The fixed frame 2 is placed on one end of the surface of the operating table 1, and the movable frame 3 is slidably set above the operating table 1 through a moving mechanism 4. It also includes a positioning mechanism 5, which is fixedly installed on the opposite side walls of the fixed frame 2 and the movable frame 3, for positioning the welding rod 6.

[0018] The positioning mechanism 5 includes fixed seats 13, which are symmetrically installed on the opposite side walls of the fixed frame 2 and the movable frame 3. The opposite side walls of the two sets of fixed seats 13 are provided with insertion holes 14, and a replaceable base 7 is inserted into the insertion hole 14 for placing the welding strip 6. It also includes a snap-fit ​​assembly for positioning the replaceable base 7 that is inserted into the socket 14.

[0019] The replaceable base 7 is inserted into the interior of the fixed base 13 by means of a snap-fit ​​assembly, and the end side wall of the replaceable base 7 is provided with a slot for placing the welding strip 6. like Figure 5 As shown, the slots at the ends of the replaceable base 7 can be made into different shapes to accommodate profiles of different shapes. When workers weld profiles of different shapes, they only need to replace the replaceable base 7.

[0020] The snap-fit ​​assembly includes a Y-shaped frame 18, which is symmetrically arranged inside the movable groove 15 opened on the inner wall of the insertion hole 14. It is snapped into the annular groove 8 on the outer arc surface of the replaceable base 7. The inner walls of the two sets of Y-shaped frames 18 are provided with snap-fit ​​blocks 24 for inserting into the slots 9 opened on the inner wall of the replaceable base 7 inside the annular groove 8. It also includes a drive module for driving the Y-frame 18 to fix the replaceable base 7 in a fixed position.

[0021] The drive module includes a gear 19 and an L-shaped frame 20. The interior of the fixed base 13 has mounting slots 16 that pass through both sides of the moving slot 15. The L-shaped frame 20 is connected to the mounting slot 16 by a connecting spring 23. The gear 19 is rotatably disposed between the L-shaped frame 20 and the Y-shaped frame 18. The toothed plates 22 disposed on the side walls opposite to the L-shaped frame 20 and the Y-shaped frame 18 are engaged and connected. The two sets of L-shaped frames 20 are provided with pressing rods 21 that pass through the side walls of the fixed base 13.

[0022] The interior of the socket 14 is connected to the buffer seat 10 via a buffer spring 17. The radius of the buffer spring 17 is smaller than the inner wall radius of the end of the Y-shaped frame 18. A convex ball is provided on the side wall of the end of the buffer seat 10 to limit the direction of the replaceable base 7 when it is inserted into the socket 14.

[0023] The fixed base 13 has mounting slots 16 on both sides of the movable slot 15. The L-shaped frame 20 inside the mounting slot 16 and the Y-shaped frame 18 inside the movable slot 15 both have toothed plates 22 on their opposite side walls. A gear 19 is rotatably connected between the Y-shaped frame 18 and the L-shaped frame 20. The gear 19 meshes with the toothed plates 22 on the side walls of the L-shaped frame 20 and the Y-shaped frame 18. A pressing rod 21 is installed through the fixed base 13 on the outer side wall of the L-shaped frame 20. When the worker needs to replace the replaceable base 7, they press the pressing rods 21 on both sides of the fixed base 13. At this time, the toothed plates 22 at the bottom of the L-shaped frame 20 drive the gear 19 to rotate, thereby causing the Y-shaped frames on both sides to rotate. The Y-shaped frame 18 is driven to move to both sides of the socket 14, causing the locking block 24 inside the Y-shaped frame 18 to be pulled out of the slot 9 opened on the side wall of the replaceable base 7. The worker only needs to pull the replaceable base 7 outward and insert the replaceable base 7, whose slot shape is the same as the shape of the required welding profile, into the socket 14. When the replaceable base 7 is pressed down until it can no longer move, the pressing rod 21 is released. At this time, the elastic force of the connecting spring 23 inside the L-shaped frame 20 squeezes the connecting spring 23 to move outward. At this time, the Y-shaped frame 18 is driven to move towards the replaceable base 7, so that the locking block 24 set on the inner wall of the Y-shaped frame 18 is inserted into the slot 9, thus realizing the replacement of the replaceable base 7, saving time and effort.

[0024] The moving mechanism 4 includes a slide groove 25 and a threaded rod 26. The slide groove 25 is formed on the surface of the operating table 1, and the threaded rod 26 is rotated inside it by rotating the rotating handle 11 that passes through the side wall end of the operating table 1. The bottom end of the moving frame 3 located inside the slide groove 25 is threadedly connected to the outer arc surface of the threaded rod 26. Guide grooves 27 are formed on both sides of the surface of the operating table 1 on the slide groove 25, which are used to limit the sliding direction of the guide blocks 12 set at both ends of the bottom of the moving frame 3.

[0025] Finally, the movable frame 3 can be moved under the drive of the movable mechanism 4. The worker manually rotates the rotating handle 11 to drive the threaded rod 26 to rotate inside the slide groove 25, thereby causing the movable frame 3, which is threaded and connected to the outside of the threaded rod 26, to move. The guide block 12 at the bottom of the movable frame 3 slides inside the guide groove 27 opened on the surface of the operating table 1. The guide groove 27 limits the direction of movement of the movable frame 3, further increasing the stability of the movable frame 3 when it moves.

[0026] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
