Description

Technical Field

[0001] This application relates to the technical field of welding fixtures, and in particular to a welding fixture for automotive magnetic switches. Background Technology

[0002] A magnetic switch for automobiles is a device that uses changes in magnetic field to control the on / off state of a circuit. During the manufacturing process, a welding point is set on each side of one end of the magnetic switch, and these two welding points need to be welded. To facilitate welding, the magnetic switch is usually positioned on a special welding fixture.

[0003] During welding, the magnetic switch is first fixed on the welding fixture, with one welding point facing the welding equipment. After welding on that side is completed, the operator manually removes the magnetic switch from the welding fixture and rotates it to make the other welding point face the welding equipment. After repositioning, the second welding is performed.

[0004] After each weld point on one side is completed, the magnetic switch must be manually rotated and repositioned. This involves many steps, resulting in low welding efficiency and making it difficult to adapt to the pace of mass production. Manual rotation may also cause positioning deviations, affecting the consistency of the welding position and thus reducing welding quality. Summary of the Invention

[0005] To address the issue of welding magnetic switches being difficult to adapt to mass production, this application provides a welding fixture for automotive magnetic switches.

[0006] This application provides a welding fixture for automotive magnetic switches, which adopts the following technical solution: A welding fixture for automotive magnetic switches includes a fixed base, a rotating shaft, and a mounting strip. The rotating shaft is rotatably mounted on the fixed base, and the mounting strip is fixedly connected to the rotating shaft. The mounting strip is provided with multiple positioning seats for placing the magnetic switches.

[0007] By adopting the above technical solution, and by setting a fixed base, a rotating shaft, and a mounting strip, multiple magnetic switches are uniformly installed on the mounting strip, which can rotate relative to the fixed base. During welding, multiple magnetic switches only need to be clamped at once, and by driving the mounting strip to rotate, all workpieces can be simultaneously flipped from one side of the welding point to the other side of the welding point, eliminating the tedious steps of manually picking up and flipping workpieces one by one. This realizes batch flipping and welding of workpieces, significantly simplifies the operation process, greatly improves welding efficiency, and is especially suitable for mass production.

[0008] Optionally, a limiting strip is slidably provided on the mounting strip along the vertical direction, and a limiting groove is provided on the fixing seat for the limiting strip to be inserted; when the limiting strip is inserted into the limiting groove, the mounting strip and the fixing seat are aligned.

[0009] By adopting the above technical solution, and by setting a sliding limit strip and a matching limit groove, a precise physical positioning reference is provided for the rotation of the mounting strip. When welding is required, the limit strip is inserted into the limit groove to ensure that the mounting strip is accurately aligned with the fixed seat, thereby ensuring the positional accuracy and consistency of the welding point relative to the welding equipment, effectively avoiding welding misalignment caused by incomplete rotation, and improving welding quality.

[0010] Optionally, the limiting strip is provided with a first magnet, and the limiting groove is provided with a second magnet, the second magnet attracting the first magnet; when the second magnet attracts the first magnet, the limiting strip is inserted into the limiting groove.

[0011] By adopting the above technical solution, a first magnet and a second magnet are set on the limiting strip and the limiting groove to attract each other. The magnetic attraction is used to generate a guiding force to assist the insertion of the limiting strip and a holding force after insertion. This not only allows the operator to obtain a clear sense of positioning, but also prevents the limiting strip from accidentally coming off due to vibration or other factors during the welding process, ensuring that the locking state of the tooling is stable and reliable during the welding process.

[0012] Optionally, a fixing slope is provided on the side of the fixing seat, and the distance between the fixing slope and the mounting strip gradually increases along the rotation direction of the mounting strip; when the mounting strip is not aligned with the fixing seat, the limiting strip can abut against the fixing slope.

[0013] By adopting the above technical solution, a fixed inclined surface with a slope is set on the side of the fixed seat, so that the limiting strip can smoothly abut against and slide along the inclined surface during the rotation of the mounting strip. The operator only needs to manually lift the limiting strip and rotate the mounting strip, so that the tooling rotation operation does not require additional control of the limiting strip, which is smoother and less labor-intensive, and improves the human-computer interaction experience.

[0014] Optionally, the positioning seat is provided with two positioning springs, and a magnetic switch is placed between the two positioning springs. The positioning springs deform in the direction of the other positioning spring.

[0015] By adopting the above technical solution, two elastically deformable positioning springs are set in the positioning seat. The magnetic switch is flexibly clamped from both sides by their deformation rebound force. This can not only adapt to certain shape tolerances of the workpiece and ensure stable clamping, but also avoid surface damage to the workpiece that may be caused by rigid clamping, thus achieving reliable and non-destructive positioning of the magnetic switch.

[0016] Optionally, the mounting strip has a through hole that connects to the positioning seat, and a movable block is slidably disposed in the through hole. The movable block is located on the deformation path of the positioning spring. When the movable block is located between the two positioning springs, the positioning springs do not clamp the magnetic switch. When the movable block is disengaged from the two positioning springs, the positioning springs clamp the magnetic switch.

[0017] By adopting the above technical solution, and by setting a sliding moving block whose movement path intersects with the deformation path of the positioning spring, mechanical active control of the clamping state of the positioning spring is achieved. When the moving block opens the positioning spring, the workpiece is in a released state, facilitating quick loading and unloading; when the moving block disengages, the spring automatically resets and clamps the workpiece. This makes the loading and unloading of workpieces easy and quick, eliminating the need for additional tools or manual prying of the spring, further improving operational efficiency.

[0018] Optionally, the movable block is disposed on the limiting strip; when the mounting strip and the fixed seat are aligned and the limiting strip is disengaged from the limiting groove, the movable block is located between the two positioning springs; when the mounting strip and the fixed seat are aligned and the limiting strip is located within the limiting groove, the movable block is disengaged from between the two positioning springs; when the mounting strip and the fixed seat are not aligned, the movable block is disengaged from between the two positioning springs.

[0019] By adopting the above technical solution, when the magnetic switch needs to be precisely aligned, the limit bar is inserted into the limit groove to lock it in place. At this time, the moving block moves downward and disengages from the positioning spring, allowing the positioning spring to clamp the magnetic switch, thus fixing the magnetic switch and the positioning seat relatively. During the flipping process, the limit bar falls due to its own weight, and the moving block falls with the limit bar, allowing the moving block to disengage from between the two positioning springs, thus clamping the magnetic switch between the two positioning springs and ensuring that the magnetic switch is stably positioned on the positioning seat. When picking up or placing the magnetic switch, the operator raises the limit bar, allowing it to disengage from the limit groove. The moving block rises with the limit bar, placing it between the two positioning springs, so that the positioning springs do not clamp the magnetic switch, facilitating the picking up and placing of the magnetic switch into the positioning seat.

[0020] Optionally, the movable block has two movable inclined surfaces, the distance between the two movable inclined surfaces gradually decreases along the direction from the limiting strip to the movable block, and the movable inclined surfaces are located on the deformation path of the positioning spring.

[0021] By adopting the above technical solution, two converging inclined surfaces are set on the moving block, which provide a smooth and gradually increasing opening force when the positioning spring is opened. This linear guidance method makes the lifting and lowering operation of the moving block smooth and effortless, reduces the impact and wear on the positioning spring, and at the same time, the inclined surface cooperation can also help the moving block to exit from between the spring more smoothly when the limit bar is released, thus improving the reliability of the mechanism.

[0022] In summary, this application includes at least one of the following beneficial technical effects: By setting up a fixed base, a rotating shaft, and a mounting strip, multiple magnetic switches are uniformly mounted on the mounting strip, which can rotate relative to the fixed base. During welding, multiple magnetic switches only need to be clamped at once, and by driving the mounting strip to rotate, all workpieces can be simultaneously flipped from one side of the welding point to the other side of the welding point, eliminating the tedious steps of manually picking up and flipping workpieces one by one. This enables batch flipping and welding of workpieces, significantly simplifies the operation process, greatly improves welding efficiency, and is especially suitable for mass production.

[0023] When precise alignment of the magnetic switch is required, the limit bar inserts into the limit slot to lock it in place. At this time, the moving block moves downward and disengages from the positioning spring, allowing the positioning spring to clamp the magnetic switch and fix it relatively to the positioning base. During the flipping process, the limit bar falls due to its own weight, and the moving block falls with the limit bar, allowing the moving block to disengage from between the two positioning springs, thus clamping the magnetic switch between the two positioning springs and ensuring that the magnetic switch is stably positioned on the positioning base. When picking up or placing the magnetic switch, the operator raises the limit bar to disengage it from the limit slot. The moving block rises with the limit bar and is positioned between the two positioning springs, preventing the positioning springs from clamping the magnetic switch and facilitating the placement of the magnetic switch in the positioning base.

[0026] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail. Example

[0027] This embodiment discloses a welding fixture for automotive magnetic switches. (Refer to...) Figure 1 A welding fixture for automotive magnetic switches includes a fixed base 1, a rotating shaft 11, and a mounting strip 2.

[0028] Reference Figure 1 The rotating shaft 11 is rotatably connected to the fixed base 1, and the mounting strip 2 is fixedly connected to the rotating shaft 11, extending along the length of the fixed base 1. Multiple positioning seats 3 are fixedly connected to the surface of the mounting strip 2 away from the fixed base 1, and the multiple positioning seats 3 are arranged in an array along the length of the mounting strip 2.

[0029] Reference Figure 1 and Figure 2 A positioning groove 31 is provided on the surface of the positioning base 3 away from the mounting strip 2, for placing the magnetic switch. A positioning protrusion 32 is integrally formed on the bottom wall of the positioning groove 31, which is used to cooperate with the corresponding groove of the magnetic switch to achieve positioning of the magnetic switch.

[0030] The implementation principle of Example 1 is as follows: the operator can rotate the mounting strip 2 to adjust the welding point on one side of the magnetic switch to the welding point on the other side of the magnetic switch, so as to realize the adjustment of the corresponding welding point of the welding equipment. Example

[0031] Reference Figure 3 and Figure 4 The difference between this embodiment and Embodiment 1 is that the mounting strip 2 has a mounting hole 21 on its surface facing the fixed base 1, and a limiting strip 4 is slidably connected within the mounting hole 21. The fixed base 1 has two limiting grooves 12 for the insertion of the limiting strip 4, and the two limiting grooves 12 are symmetrically arranged along the rotation axis 11. When the limiting strip 4 is inserted into the limiting groove 12, the mounting strip 2 and the fixed base 1 are aligned, that is, the length direction of the mounting strip 2 is the same as the length direction of the fixed base 1.

[0032] Reference Figure 4 A first magnet 41 is fixedly connected to the end face of the limiting strip 4, and a second magnet 121 is fixedly connected to the bottom wall of the limiting groove 12. The second magnet 121 attracts the first magnet 41. When the second magnet 121 attracts the first magnet 41, the limiting strip 4 is inserted into the limiting groove 12.

[0033] Reference Figure 4 and Figure 5 A receiving groove 22 is formed on the surface of the mounting strip 2 away from the rotating shaft 11, and the receiving grooves 22 are arranged in an array along the length direction of the mounting strip 2. Two through holes 33 are formed on the end face of the positioning seat 3, and the through holes 33 connect to the positioning groove 31. The positioning seat 3 is welded and fixedly connected to the mounting strip 2, at which time the through holes 33 connect to the receiving groove 22.

[0034] Reference Figure 4 and Figure 5 Two positioning springs 34 are fixedly connected to the wall of the through hole 33. The two positioning springs 34 are symmetrically arranged along the axial direction of the positioning groove 31. The deformed end of the positioning spring 34 can extend into the positioning groove 31 from the through hole 33, so that the two positioning springs 34 can clamp the magnetic switch and fix the magnetic switch in the positioning seat 3.

[0035] Reference Figure 4 and Figure 6 A connecting strip 42 is fixedly connected to the surface of the limiting strip 4 away from the first magnet 41. The connecting strip 42 and the limiting strip 4 are arranged perpendicularly to each other, and the length direction of the connecting strip 42 is the same as the length direction of the mounting strip 2. Multiple moving blocks 43 are fixedly connected to the surface of the connecting strip 42 away from the limiting strip 4, and the multiple moving blocks 43 are arranged in an array along the length direction of the connecting strip 42. The connecting strip 42 is first placed in the receiving groove 22, and then multiple positioning seats 3 are welded to the mounting strip 2.

[0036] Reference Figure 4 and Figure 6 Movable ramps 44 are provided on the surfaces of opposite sides of the movable block 43. The distance between the two movable ramps 44 gradually decreases along the direction from the limiting strip 4 to the movable block 43. The moving path of the movable ramps 44 intersects with the deformation path of the positioning spring 34.

[0037] Reference Figure 4 and Figure 6 When the moving block 43 extends between the two positioning springs 34, the moving block 43 pushes the positioning spring 34 to deform in a direction away from the other positioning spring 34, causing the positioning spring 34 to release its clamping of the magnetic switch. When the moving block 43 disengages from between the two positioning springs 34, the positioning springs 34 return to their original position, allowing the two positioning springs 34 to clamp the magnetic switch again.

[0038] Reference Figure 4 and Figure 6 In the welding state, when the mounting strip 2 and the fixed seat 1 are aligned and the limiting strip 4 is located in the limiting groove 12, the moving block 43 disengages from the two positioning springs 34, allowing the two positioning springs 34 to clamp the magnetic switch, thereby achieving relative fixation between the magnetic switch and the positioning seat 3, so that the welding point of the magnetic switch can be stably aligned with the welding equipment during the welding process.

[0039] Reference Figure 4 and Figure 6 With the mounting strip 2 and the fixed seat 1 released from their relative fixed state, the worker lifts the limiting strip 4, allowing the limiting strip 4 to disengage from the limiting groove 12, thus releasing the relative fixation between the mounting strip 2 and the fixed seat 1, so that the worker can rotate the mounting strip 2 to align the welding point on the other side with the welding equipment.

[0040] Reference Figure 4and Figure 6 When the mounting strip 2 and the fixed seat 1 are misaligned during rotation, the limiting strip 4 falls due to the weight of the limiting strip 4, the connecting strip 42 and the moving block 43. The moving block 43 can disengage from the two positioning springs 34, so that the two positioning springs 34 can clamp the magnetic switch, thereby fixing the magnetic switch and the positioning seat 3 to reduce the wobbling of the magnetic switch in the positioning seat 3 during rotation.

[0041] Reference Figure 4 and Figure 6 When the magnetic switch is in the pick-and-place state, the staff lifts the limit bar 4 to disengage the limit bar 4 from the limit groove 12, thereby releasing the relative fixation between the mounting bar 2 and the fixing seat 1, so that the magnetic switch can be picked up and placed from the positioning seat 3.

[0042] Reference Figure 3 and Figure 4 The fixed base 1 has fixed inclined surfaces 13 on its opposite sides. The two fixed inclined surfaces 13 are arranged in a circumferential array along the rotation axis 11, and are located on different sides of the length of the fixed base 1. The distance between the fixed inclined surfaces 13 and the mounting strip 2 gradually increases along the rotation direction of the mounting strip 2. During the rotation of the limiting strip 4, the limiting strip 4 can move along the fixed inclined surfaces 13 to the surface of the fixed base 1 facing the mounting strip 2.

[0043] The implementation principle of Example 2 is as follows: The operator first lifts the limiting strip 4, allowing it to disengage from the limiting groove 12. Then, the operator rotates the mounting strip 2, allowing the limiting strip 4 to disengage from the fixed seat 1. At this time, the limiting strip 4 falls, allowing the moving block 43 to disengage from between the two positioning springs 34, so that the two positioning springs 34 can clamp the magnetic switch until the limiting strip 4 moves along the fixed inclined surface 13, allowing the limiting strip 4 to abut against the surface of the fixed seat 1 facing the mounting strip 2. As the mounting strip 2 continues to rotate, the limiting strip 4 can be inserted into the limiting groove 12, achieving alignment between the mounting strip 2 and the fixed seat 1, that is, the welding point on the other side can be aligned with the welding equipment.
