DETAILED DESCRIPTION

[0022] The present invention will be further described below in conjunction with specific drawings.

[0023] See also Figure 1 The hanging core includes a cross bar 100, and a fixing part 110 and an elastic part 120 respectively welded at both ends of the cross bar 100, and the outer walls of the fixing part 110 and the elastic part 120 are connected with a head screw 140. A welding jig for the hanging core of an anode hanger is used to fix the hanging core during welding. Please refer to Figure 2 The welding fixture includes a base 200, a first positioning mechanism 300 disposed on the base 200 for fixing the fixing portion 110, a second positioning mechanism 400 disposed on one side of the first positioning mechanism 300 for fixing the elastic portion 120, and a third positioning mechanism 500 disposed between the first positioning mechanism 300 and the second positioning mechanism 400 for fixing the crossbar 100. Figure 4, the fixing part 110 fixed on the first positioning mechanism 300 can be abutted against one end of the cross bar 100 fixed on the third positioning mechanism 500, and the distance between the elastic part 120 and the other end of the cross bar 100 can be adjusted through the second positioning mechanism 400 until it can abut against the cross bar 100. The first positioning mechanism 300 and the second positioning mechanism 400 are both provided with a plurality of avoidance grooves 600 for avoiding corresponding components when the bottom surface of the hanging core is turned over for welding. When welding the hanging core, the fixing part 110, the cross bar 100 and the elastic part 120 constituting the hanging core are respectively firmly fixed on the top of the base 200 by the corresponding positioning mechanisms, and the two ends of the fixed cross bar 100 can be connected to the fixing part 110 and the elastic part 120 respectively, and the processing personnel then weld the contact points. When welding the bottom surface after turning over, a corresponding avoidance groove 600 is provided to avoid the components on the hanging core (i.e., the head screw 140), and the fixing position and method are inconvenient, the operation is simple and convenient, and the finished product precision and processing efficiency of the hanging core are improved. In addition, the position of the second positioning mechanism 400 can be adjusted according to the different lengths of the crossbar 100, and the versatility of the welding fixture is stronger.

[0024] The base 200 is provided with a mounting groove 210 recessed toward the bottom surface of the base 200, and the mounting groove 210 is provided with a plurality of connection holes 211 spaced apart along the length direction of the mounting groove 210, and the second positioning mechanism 400 is screwed to the connection hole 211 via a bolt 700. The disassembly and assembly of the second positioning mechanism 400 is simple and easy to operate, and the position of the elastic part 120 can be quickly locked.

[0025] The first positioning mechanism 300 includes a third positioning block 310, a positioning assembly 330 and a fourth positioning block 320 which are screwed to the upper end of the base 200 by bolts 700. The third positioning block 310, the positioning assembly 330 and the fourth positioning block 320 are arranged at intervals along the width direction of the base 200. The top surface of the third positioning block 310 has a second limit block 311 protruding in a direction away from the top surface of the third positioning block 310, and the second limit block 311 can limit the position of the fixing part 110 on one side of the fixing part 110. The top surface of the fourth positioning block 320 has a third limit block 321 protruding in a direction away from the top surface of the fourth positioning block 320, and the third limit block 321 can abut against one end of the fixing part 110. The fixing part 110 is a straight rod. When the first end of the fixing part 110 is placed on the third positioning block 310, the second limit block 311 is used to limit the position on the outer wall of the fixing part 110. When the second end of the fixing portion 110 is placed on the fourth positioning block 320 , the third limiting block 321 is L-shaped and can abut against the second end, and part of the third limiting block 321 also abuts against the outer wall of the fixing portion 110 .

[0026] The positioning assembly 330 is distributed between the third positioning block 310 and the fourth positioning block 320. The positioning assembly 330 includes a fifth positioning block 331 connected to the base 200, a fourth limiting block 332 formed by protruding from the top surface of the fifth positioning block 331 in a direction away from the fifth positioning block 331, a second pressing block 333 detachably connected to the upper end of the fourth limiting block 332 for pressing the fixing part 110 above the fixing part 110, and a second movable block 334 provided on one side of the fourth limiting block 332 for pressing the fixing part 110 on one side of the fixing part 110. The plurality of avoidance grooves 600 provided on the second mechanism are respectively distributed at corresponding positions of the third positioning block 310 and the fourth positioning block 320. When welding the bottom surface of the hanging core, after turning the hanging core over, the protruding head screw 140 is accommodated in the avoidance groove 600, which facilitates the smooth welding of the bottom surface of the hanging core. In the top view of the orthographic projection plane, the second movable block 334 is located between the two second holding blocks 333 and is lower than the second holding block 333. The second movable block 334 can reciprocate in the direction of approaching or moving away from the fourth limit block 332. The side wall of the fourth limit block 332 is screwed with a second locking bolt 3320 that can abut against the side wall of the second movable block 334. The second locking bolt 3320 can push the second movable block 334 to move toward the direction of approaching the fixed part 110 until the fixed part 110 is pressed tightly. When the fixed part 110 is on the third positioning block 310 and the fourth positioning block 320, the second locking bolt 3320 is rotated to push the second movable block 334 to press the other side of the fixed part 110 tightly, which is equivalent to the second movable block 334 working together with the second limit block 311 and the third limit block 321 to clamp and fix the fixed part 110 to prevent the fixed part 110 from moving horizontally. All second pressing blocks 333 are provided with long holes that vertically penetrate the second pressing blocks 333 . Bolts 700 are installed in the long holes and connected to the base 200 , so that the second pressing blocks 333 can be pressed on the top surface of the fixing part 110 to prevent the fixing part 110 from moving in the vertical direction.

[0027] The second positioning mechanism 400 includes a base 410, two first positioning blocks 420 integrally protruding from the top surface of the base 410 in a direction away from the base 410, a second positioning block 430 disposed between the two first positioning blocks 420, two first holding blocks 440 detachably connected to the upper end of the second positioning block 430 for pressing the elastic part 120 above the elastic part 120, and a first movable block 450 disposed on one side of the second positioning block 430 for pressing the elastic part 120 on one side of the elastic part 120. The two first positioning blocks 420 are symmetrically arranged on both sides of the base 410 for respectively correspondingly limiting the two ends of the elastic part 120, and a plurality of avoidance grooves 600 disposed on the base 410 are respectively distributed adjacent to the first positioning blocks 420 in a one-to-one correspondence. The two first positioning blocks 420 are also L-shaped, and the two first positioning blocks 420 surround the two ends of the elastic part 120 to limit the movement of the elastic part 120.

[0028] All the first holding blocks 440 are provided with a mounting hole 441 vertically penetrating the first holding blocks 440, and the mounting hole 441 is preferably a long hole. The first holding block 440 is screwed to the base 410 by a bolt 700 passing through the mounting hole 441 so that one end of the first holding block 440 can be pressed on the top surface of the second positioning block 430, and the other opposite end can be pressed on the top surface of the elastic portion 120. The holding operation mode of the first holding block 440 is the same as that of the second holding block 333, and the structures of the first holding block 440 and the second holding block 333 are also the same, which is not only simple and easy to operate, but also can reduce the difficulty of manufacturing, and can achieve the purpose of holding and fixing even if mixed.

[0029] In the top view of the orthographic projection plane, the first movable block 450 is located between the two first holding blocks 440, and the first movable block 450 can reciprocate in the direction of approaching or moving away from the second positioning block 430. The side wall of the second positioning block 430 is screwed with a first locking bolt 451 that can abut against the side wall of the first movable block 450, and the first locking bolt 451 can push the first movable block 450 to move toward the direction of approaching the elastic part 120 until the elastic part 120 is pressed tightly. Rotating the first locking bolt 451 until it contacts the first movable block 450 can push the first movable block 450 to press against the elastic part 120 in the middle of the outer side of the elastic part 120 for fixing. The first movable block 450 and the second movable block 334 have the same structure, and the first movable block 450 and the second movable block 334 not only play the role of fastening the parts to be welded, but the second movable block 334 presses against the welding position in the middle of the fixing part 110, and the first movable block 450 and the second movable block 334 both press against the welding position, effectively preventing the parts from being deformed due to high temperature during the welding process.

[0030] When the hanging core is loaded with the notebook shell, the two ends of the arc-shaped elastic part 120 need to be bent inwardly in the direction of approaching each other to complete the assembly. In order to extend the service life of the hanger and enhance the strength of the welding point between the cross bar 100 and the elastic part 120, a rectangular reinforcing sheet 130 is usually placed between the cross bar 100 and the elastic part 120, and the two sides of the reinforcing sheet 130 are respectively welded to the corresponding cross bar 100 and the elastic part 120. After that, when loading the workpiece again, the two ends of the elastic part 120 are pressed internally, and the bending force points are at the two ends of the reinforcing sheet 130, rather than at the welding point between the cross bar 100 and the elastic part 120, so the service life of the hanging core can be extended. Please refer to Figure 3 A cushion block 460 and a first limit block 470 are integrally extended from the top surface of the base 410 in a direction away from the base 410. The cushion block 460 can support the cross bar 100 below and support the cross bar 100 at a position close to the welding point to facilitate stable and firm welding.

[0031] When the elastic portion 120 and the cross bar 100 are welded via the reinforcing sheet 130, the first limiting block 470 is located on one side of the cushion block 460 to abut against the reinforcing sheet 130 to limit the movement of the reinforcing sheet 130, thereby limiting the position of the reinforcing sheet 130 and preventing the displacement of the reinforcing sheet 130 from affecting welding.

[0032] The third positioning mechanism 500 includes a plurality of sixth positioning blocks 510 connected to the base 200 and distributed at intervals, a plurality of seventh positioning blocks 520 respectively corresponding to and adjacent to the sixth positioning blocks 510, and a plurality of clamps 530 respectively corresponding to and connected to the upper ends of the seventh positioning blocks 520. Each of the sixth positioning blocks 510 is provided with a receiving groove 511 which runs through the sixth positioning block 510 horizontally for receiving the cross bar 100, and a third locking bolt 512 for locking the cross bar 100 in the receiving groove 511 is screwed on the side wall of the sixth positioning block 510. The clamp 530 can be pressed on the top surface of the cross bar 100 to limit the position of the cross bar 100. The clamp 530 is preferably a cantilever toggle clamp, which is installed on the upper end of the seventh positioning block 520 by bolts 700. When the crossbar 100 is accommodated in the accommodation groove 511 , the third locking bolt 512 is rotated, and the third locking bolt 512 is tightly pressed against the side wall of the crossbar 100 , and the clamp 530 is pressed on the crossbar 100 to enhance the stability of the crossbar 100 .

[0033] The welding jig for the hanging core: 1. It is specially designed for welding hanging cores. It can stably and firmly fix the various components constituting the hanging core through the corresponding positioning mechanism. The fixing position and fixing method are standardized, and the hanger has higher precision after welding. 2. After completing the welding of the top surface of the hanging core, turn the entire hanging core over, and still use the corresponding positioning mechanism to fix the fixing part 110, the cross bar 100 and the elastic part 120. The fixing method is simple and easy to operate, and the corresponding position is provided with an avoidance groove 600 to avoid the corresponding components, which can conveniently and quickly operate double-sided welding and improve work efficiency. 3. In the actual production process of notebook accessories, since notebook accessories have different sizes, the matching hanging cores also need to be produced in various sizes, and the change in the size of the hanging core lies in the change in the length of the cross bar 100. Through the second positioning mechanism 400 that can be moved and adjusted on the base 200, the fixed position of the elastic part 120 can be adjusted and changed with the different lengths of the cross bar 100, so as to adapt to the processing and use of hanging cores of more different sizes. Fourth, after the elastic part 120 and the fixing part 110 are fixed, the first movable block 450 and the second movable block 334 are both in contact with the corresponding positions close to the welding point, effectively preventing the parts to be welded from being deformed due to high temperature during the welding process.

[0034] The above are only implementation methods of the present utility model, and are not intended to limit the patent scope of the present utility model. Any equivalent structure made using the contents of the specification and drawings of the present utility model, directly or indirectly used in other related technical fields, are also within the patent protection scope of the present utility model.
