Description

Technical Field

[0001] This utility model relates to the field of welding auxiliary technology, specifically a welding positioning fixture for aluminum substrates of a table lamp. Background Technology

[0002] Aluminum substrate for desk lamps is a copper-clad laminate with a metal base used in desk lamps. It mainly consists of a circuit layer, an insulating layer, and a metal base layer. The power devices in the desk lamp are surface-mounted on the circuit layer of the aluminum substrate. When the devices are running, they generate heat, which is quickly conducted to the metal base layer through the insulating layer. Then, the metal base layer dissipates the heat to the surrounding environment, thereby achieving heat dissipation for the devices, maintaining the normal operating temperature of the desk lamp, and ensuring its performance and lifespan. Therefore, a welding positioning device is needed for auxiliary support during assembly to ensure stable and convenient mounting. In response, Chinese patent application number CN202021985131.7 discloses an LED aluminum substrate welding positioning structure, including a frame, an angle adjustment mechanism, a fixing unit, and a smoke exhaust unit. The frame has a graduated dial fixed to its inner side, which is rotatably connected to a positioning platform via a first bearing. Indicator pins are evenly distributed along the edge of the positioning platform, with each pin corresponding to a graduation on the graduated dial. The angle adjustment mechanism is installed inside the frame, and its adjustment mechanism is connected to the bottom of the positioning platform via a connecting shaft. The fixing unit includes a pressure plate, an electric push rod, and a rotary joint. The electric push rod is installed at the top center of the frame, and the pressure plate is rotatably connected to the telescopic end of the electric push rod via the rotary joint. The pressure plate is located directly above the positioning platform. The smoke exhaust unit is installed on the side of the frame.

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.

[0015] Please see Figures 1-5 One embodiment provided by this utility model: A welding and positioning fixture for an aluminum substrate of a table lamp includes a positioning frame 100, a side clamping assembly 110 mounted on the side wall of the positioning frame 100, a flipping assembly 120 mounted at the corners of both ends of the positioning frame 100, a side bracket 130 supported at the bottom of the flipping assembly 120, a base plate 131 fixedly mounted at the bottom of the side bracket 130, and a rotating assembly 140 supported at the bottom of the base plate 131.

[0016] As described in more detail in this embodiment, the four-sided clamping components 110 are symmetrically and evenly distributed in the middle of the four-sided side walls of the positioning frame 100. The side clamping components 110 include side clamps 111, a side slide rod 112 is fixedly provided on the back of the side clamps 111, a side support sleeve 113 is sleeved on the outside of the side slide rod 112, and the side support sleeve 113 is fixedly provided on the side wall of the positioning frame 100.

The limiting sleeve 117 is fixed to the outer side wall of the side clamp assembly 110. The sliding rod 112 has evenly distributed insertion holes 118 corresponding to the pin 116 inside, and a rubber pad 119 is fixed inside the groove at the front end of the side clamp 111.

[0019] Therefore, during assembly and use, it is convenient to provide auxiliary limiting support when clamping the plate. At the same time, with the cooperation of the rubber clamping pad 119, it is convenient to maintain the side of the plate, making operation and use more convenient.

[0020] As described in more detail in this embodiment, the flipping assembly 120 includes a side end 121, and two sets of side end 121 are symmetrically fixed at the corner of the side end of the positioning frame 100. A side rotating shaft 122 is fixed at the outer end of the side end 121. An upper clamp 123 is assembled on the top of the side bracket 130 by screws, and the side rotating shaft 122 is externally assembled between the top of the side bracket 130 and the upper clamp 123 by bearing insertion.

[0021] Therefore, during assembly and use, it is convenient to provide auxiliary support and rotation as needed, making subsequent operations and flipping more convenient.

[0022] As described in more detail in this embodiment, the top surface of the upper clamp 123 is fixed with an upper protrusion 124, and the upper and lower ends of the side end 121 are respectively provided with limiting protrusions 125. The inner end of the upper protrusion 124 is threaded with a screw pin 126, the inner end of the screw pin 126 is inserted into the limiting protrusion 125, and the outer end of the screw pin 126 is fixed with a rotating ring 127.

[0023] Therefore, during assembly and use, it is convenient to provide limiting support when flipping, making operation and use more convenient and facilitating subsequent stable auxiliary welding.

[0024] As described in more detail in this embodiment, the rotating assembly 140 includes a chassis 141, a bottom shaft 142 is fixedly disposed at the center of the surface of the chassis 141, and the bottom shaft 142 is inserted into the middle of the base plate 131 through a bearing. An upper ring 143 is fixedly disposed on the middle surface of the base plate 131, and the upper ring 143 is sleeved on the outside of the bottom shaft 142. A reinforcing rib 132 is provided between the side of the side bracket 130 and the base plate 131.

[0025] Therefore, during assembly and use, it is convenient to provide auxiliary rotation support according to the needs of use, and it is also convenient to assist in rotation during welding.

[0026] As described in more detail in this embodiment, an upper rotating sleeve 144 is fitted onto the upper end of the bottom shaft 142, and the upper end of the upper rotating sleeve 144 is fastened to the upper end of the bottom shaft 142 by fastening bolts 145.

[0027] Therefore, during assembly and use, it is easy to rotate and retain the position as needed, making subsequent welding operations more convenient.

[0028] Working principle: During assembly and use, the side clamps 111, side slide rods 112, and side support sleeves 113 work together to facilitate the adjustment of the distance between the four side clamps 111. Then, with the cooperation of rubber pads 119, the plate is clamped between the four sets of side clamps 111. The springs 114 help maintain the elastic clamping force, making operation more convenient. After clamping, the pins 116 are inserted into the corresponding holes 118 to maintain the limit position. Furthermore, when welding requires flipping, the side rotating shaft 122 and bearings facilitate the auxiliary flipping of the side end 121 and the positioning frame 100, thereby causing the plate clamped by the side clamping assembly 110 to flip. This makes welding more convenient. Subsequently, with the cooperation of the upper protrusion 124 and the limiting protrusion 125, the pin 116 keeps the limit in place, which facilitates subsequent welding. Similarly, during welding, the cooperation of the chassis 141 and the bottom shaft 142 facilitates the auxiliary rotation of the opposite support 130 and the base plate 131, thereby driving the plate to rotate. This allows for rotation to the appropriate position according to welding needs, making the operation more convenient. After rotation, the torsion bar 147 facilitates the tightening of the locking pin 146, so that the inner end of the locking pin 146 abuts against the outer wall of the upper ring 143, which facilitates the limiting and holding of the bottom shaft 142 and the base plate 131, thus facilitating the auxiliary positioning operation for welding. The operation ends here.
