Description

Technical Field

[0001] This utility model relates to the field of welding technology for profiles such as T-shaped steel, flat iron, and bulb flat steel, and particularly to a magnetic welding positioner for profiles. Background Technology

[0002] In the installation of T-shaped steel, flat iron, and bulb flat steel, welding positioners are required to align the installation position lines. Traditional magnetic welding positioners have the following problems:

[0003] 1. The adjustment positioning device is connected to the magnet of the fixed plate below, so that the linear positioning height is singular and it is only suitable for positioning at one height.

[0004] 2. The permanent magnets under traditional welding positioners are large and heavy, and they remain attached to the sheet metal after use, making them difficult to remove. Summary of the Invention

[0005] To adjust the height of the welding positioner during welding operations and enable the magnetic force of the magnet within the positioner to open and close for easy handling, thereby improving work efficiency, this utility model provides a profile magnetic welding positioner, comprising an L-shaped alloy frame, a workpiece positioning device, and a magnetic base. The magnetic base is fixedly disposed on the bottom surface of the L-shaped alloy frame for adsorbing the positioner onto the plate to be welded. The workpiece positioning device is fixedly disposed on the vertical surface of the L-shaped alloy frame for fixing the position of the workpiece to be welded. Its characteristic is:

[0006] The workpiece positioning device further includes a base installed on the facade of the L-shaped alloy frame and a threaded rod that horizontally penetrates the base. The threaded rod is threadedly connected to the base and can be screwed in and out of the base. A top head is provided on the outer end of the threaded rod, and a ratchet wrench is provided on the inner tail end of the threaded rod.

[0007] The left and right sides of the L-shaped alloy frame are provided with corresponding positioning holes evenly distributed from top to bottom. The base is fixed to the positioning holes by bolts. By selecting different positioning holes, the fixed position of the base can be changed, the height of the base can be adjusted, and thus the height of the workpiece positioning device can be adjusted.

[0008] The magnetic base is equipped with a magnetic base switch handle, which is connected to the magnet assembly inside the magnetic base. Rotating the magnetic base switch handle can drive the magnet assembly to rotate inside the magnetic base, thereby realizing the magnetic opening and closing of the magnetic base.

[0009] The mandrel can rotate on the threaded screw to adjust its front and rear positions, thereby adjusting the positioning of the workpiece to be welded. The mandrel is provided with a through hole, and a through pin is provided in the through hole. The through pin is used to fix the adjusted mandrel on the threaded screw.

[0010] The top of the L-shaped alloy frame is provided with reinforcing ribs to fix the left side frame and the right side frame together and to improve the overall stability of the L-shaped alloy frame.

[0011] The magnetic base includes a housing, a front cover, a rear cover, and an internal magnet assembly. The housing is an iron cuboid, and the magnet assembly is a cylindrical permanent magnet. The housing has a horizontal cylindrical cavity inside, which encloses the cylindrical magnet assembly. The magnet assembly can rotate around an axis within the cylindrical cavity. A magnetic base switch handle is located on the front side of the front cover. Rotating the magnetic base switch handle causes the magnet assembly to rotate within the housing.

[0012] The bottom surface of the housing is provided with a magnetic attraction surface and a magnetic isolation cavity. The iron housing is further divided into a left magnetic guide and a right magnetic guide. The cylindrical center longitudinal section of the magnet assembly serves as the dividing surface, and the magnet assembly is divided into N poles and S poles. When the magnetic base switch handle is rotated, and the N pole and S pole of the magnet assembly are distributed to the left and right, the N pole is connected to the left magnetic guide and the S pole is connected to the right magnetic guide. At this time, the magnetic lines of force start from the N pole and are transmitted to the left magnetic guide. Since there is a magnetic isolation cavity at the bottom of the housing, the magnetic lines of force cannot be directly transmitted from the left magnetic guide to the right magnetic guide. Instead, they enter the plate after passing through the magnetic attraction surface of the left magnetic guide, then enter the right magnetic guide through the magnetic attraction surface of the right magnetic guide, and finally reach the S pole, forming a magnetic closed loop. At this time, the plate is attracted to the bottom surface of the housing.

[0013] When the magnetic base switch handle is rotated, and the N pole and S pole of the magnet assembly are distributed vertically, both the N pole and S pole are connected to the left and right guiding magnets. At this time, the magnetic lines of force are divided into two closed loops. The left closed loop is transmitted directly from the N pole to the S pole through the left guiding magnet, and the right closed loop is transmitted directly from the N pole to the S pole through the right guiding magnet. Since no magnetic lines of force pass through the plate, it cannot be attracted to the bottom surface of the shell.

[0014] The magnetic base switch handle is fixedly connected to the front end face of the magnet assembly via a shaft that passes through the front cover. The left and right magnetic guides are spliced ​​together, forming the cylindrical cavity inside. Their bottom surfaces together form the bottom surface of the housing, i.e., the bottom surface of the magnetic base. Both the left and right magnetic guides have magnetic attraction surfaces and magnetic isolation surfaces on their bottom surfaces. The magnetic attraction surfaces are horizontal, and the magnetic isolation surfaces are located inside the magnetic attraction surfaces and are inclined upwards. When the housing is placed vertically on the plate, the magnetic attraction surfaces of the left and right magnetic guides are in close contact with the upper surface of the plate. At this time, the magnetic isolation surfaces of the left and right magnetic guides and the upper surface of the plate below them are combined to form the magnetic isolation cavity in the lower part of the housing.

[0015] The magnet assembly consists of two or more cylindrical magnets and connecting blocks connected to each other. The cylindrical magnets are arranged at intervals, and each pair of adjacent cylindrical magnets is connected by a connecting block. The connecting block is made of aluminum and is embedded between the two adjacent cylindrical magnets through grooves on both sides of the cylindrical magnets.

[0016] Advantages of this utility model:

[0017] 1. The magnetic base has a switch. The magnetic adsorption surface at the bottom can be used to control the adsorption and release of the workpiece. After the welding operation is completed, the magnetism can be turned off, making it easy to remove the magnetic pressure device adsorbed on the workpiece. This reduces workload, improves work efficiency, and is highly practical.

[0018] 2. The height of the positioning device is adjustable, making it suitable for a wide range of applications. Attached Figure Description

The workpiece positioning device is fixedly disposed on the vertical surface of the L-shaped alloy frame for fixing the position of the workpiece 4 to be welded. Its characteristic is:

[0028] The workpiece positioning device includes a base 5 installed on the facade of the L-shaped alloy frame 1 and a threaded rod 6 that horizontally penetrates the base 5. The threaded rod 6 is threadedly connected to the base 5 and can be screwed in and out of the base 5.

The base 5 is fixed to the positioning holes 9 by bolts 10. By selecting different positioning holes 9, the fixed position of the base 5 can be changed, the height of the base 5 can be adjusted, and thus the height of the workpiece positioning device can be adjusted.

[0030] The magnetic base 2 is provided with a magnetic base switch handle 11, which is connected to the magnet assembly 12 inside the magnetic base 2. Rotating the magnetic base switch handle 11 can drive the magnet assembly 12 to rotate inside the magnetic base 2, thereby realizing the magnetic opening and closing of the magnetic base 2.

[0031] The mandrel 7 can rotate on the threaded screw 6 via the thread to adjust the front and rear position of the mandrel 7, thereby adjusting the positioning of the workpiece 4 to be welded. The mandrel 7 is provided with a through hole 13, and a through pin is provided in the through hole 13. The through pin is used to fix the adjusted mandrel 7 on the threaded screw 6.

The iron housing 15 is further divided into a left guiding magnet 15-1 and a right guiding magnet 15-2. Taking the cylindrical center longitudinal section of the magnet assembly 12 as the dividing surface, the magnet assembly 12 is divided into N pole 12-1 and S pole 12-2. When the magnetic base switch handle 11 is rotated, and the N pole 12-1 and S pole 12-2 of the magnet assembly 12 are distributed left and right, the N pole 12-1 is connected to the left guiding magnet 15-1, and the S pole 12-2 is connected to the right guiding magnet 15-2. At this time, the magnetic lines of force start from the N pole 12-1 and are transmitted to the left guiding magnet. 15-1. Because there is a magnetically shielded cavity 19 at the bottom of the housing 15, the magnetic lines of force cannot be directly transmitted from the left magnetic conductor 15-1 to the right magnetic conductor 15-2. Instead, they enter the plate 3 through the magnetic attraction surface 18 of the left magnetic conductor 15-1, and then enter the right magnetic conductor 15-2 through the magnetic attraction surface 18 of the right magnetic conductor 15-2. Finally, they are transmitted to the S pole 12-2, forming a magnetic closed loop. At this time, the plate 3 is attracted to the bottom surface of the housing 15.

At this time, the magnetic lines of force are divided into two closed loops. The left closed loop starts from the N pole 12-1 and passes directly through the left guide magnet 15-1 to the S pole 12-2. The right closed loop starts from the N pole 12-1 and passes directly through the right guide magnet 15-2 to the S pole 12-2. Since there are no magnetic lines of force passing through the plate 3, it cannot be attracted to the bottom surface of the housing 15.

[0036] The magnetic base switch handle 11 is fixedly connected to the front end face of the magnet assembly 12 via a shaft head 20 that passes through the front cover 16. The left guide magnet 15-1 and the right guide magnet 15-2 are spliced ​​together, forming the cylindrical cavity inside, and their bottom surfaces are combined to form the bottom surface of the housing 15, that is, the bottom surface of the magnetic base 2.

When the housing 15 is placed vertically on the plate 3, the magnetic attraction surfaces 18 of the left magnetic conductor 15-1 and the right magnetic conductor 15-2 are closely attached to the upper plane of the plate 3. At this time, the magnetic isolation surfaces 21 of the left magnetic conductor 15-1 and the right magnetic conductor 15-2 and the upper surface of the plate 3 below them are combined together to form the magnetic isolation cavity 19 in the lower part of the housing 15.

[0037] The magnet assembly 12 is composed of two or more cylindrical magnets 22 and connecting blocks 23 connected to each other. The cylindrical magnets 22 are arranged at intervals, and each pair of adjacent cylindrical magnets 22 is connected by a connecting block 23. The connecting block 23 is made of aluminum and is embedded between the two adjacent cylindrical magnets 22 through the grooves on both sides of the cylindrical magnets 22.
