Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically to a welding mold for the output shaft of an automobile steering wheel. Background Technology

[0002] The steering wheel output shaft is a key component of a car's steering system, responsible for converting the rotation of the steering wheel into steering motion of the wheels. Welding is crucial in the manufacturing process of this component because it not only affects the accuracy and reliability of the steering system but also directly impacts vehicle safety. A welding mold for the automotive steering wheel output shaft is a fixture that ensures stability during welding, thereby improving the quality of the welding process.

[0003] Common output shaft welding molds typically consist of an upper (left) mold and a lower (right) mold. The upper mold is responsible for positioning and fixing the output shaft, while the lower mold works in conjunction with the upper mold to complete the welding task. However, this method results in the output shaft being fixed in position after being clamped by the upper and lower molds. Therefore, during circumferential welding, after welding the top surface, the mold needs to be removed and the output shaft flipped and clamped again before welding the other side of the output shaft. This makes the entire process time-consuming and labor-intensive. Furthermore, the secondary clamping can easily lead to inaccurate positioning of the output shaft, making it impossible to guarantee the consistency and repeatability of the two clamping operations, thereby reducing the accuracy of the output shaft welding. In addition, the number of physical contacts during the secondary clamping increases the risk of workpiece damage caused by clamping, which cannot meet the working requirements of output shaft welding. Therefore, a welding mold for automotive steering wheel output shafts is proposed. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a welding mold for the output shaft of an automotive steering wheel, which solves the technical problem that the fixed clamping position of the output shaft requires secondary clamping when welding at different angles, resulting in a time-consuming and labor-intensive process.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a welding mold for an automotive steering wheel output shaft, comprising:

[0008] The base has a mounting seat on its top. A sliding groove is provided in the middle of the interior of the mounting seat. An assembly block is inserted into the middle of the sliding groove. A bearing is inserted into the interior of the assembly block.

[0009] A double-tooth lead screw is inserted inside the bearing. Movable seats are inserted on both the left and right sides of the slide groove. Both ends of the double-tooth lead screw pass through the interior of the movable seats.

[0010] A mold base is installed on top of a movable base. A rotating shaft is inserted inside the mold base. A clamping mold is coaxially installed on the inner end of each rotating shaft. A turntable is coaxially connected to the left end of the rotating shaft on the left side. A first handwheel is coaxially installed on the left end of the double-tooth screw.

[0011] Preferably, the threads on the left and right sides of the double-threaded screw are arranged in opposite directions, the length of the double-threaded screw is greater than that of the mounting base, and the outer middle position of the mounting base is connected to the inner ring of the bearing, thereby improving the rotational stability of the double-threaded screw.

[0012] Preferably, each clamping mold has a clamping groove in the middle of its interior. A screw is screwed onto the top of each clamping mold at the middle of the clamping groove. A pressure plate is mounted on the bottom of each screw via a ball bearing. The pressure plate can be moved up and down by rotating the screw, so that the output shaft can be pressed into the clamping mold first after it is inserted, preventing movement when the clamping mold is closed.

[0013] Preferably, the turntable is circumferentially mounted with levers, and the number of levers is 3-6 sets. Limiting bolts are screwed onto the inner and outer sides of the turntable, and a second handwheel is coaxially mounted on the left end of the limiting bolt. By rotating the limiting bolt, its right end can contact the left side of the mold base, thereby restricting the rotation of the turntable. This prevents the turntable and the shaft from moving again after rotating to the corresponding angle, thus improving the stability of the welding after adjustment.

[0014] Preferably, the bottom of both the slide and the movable seat is trapezoidal, the left and right ends of the slide are open through, and the width of the movable seat is one-quarter of the width of the slide, thereby increasing the range of motion of the movable seat.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a welding mold for the output shaft of an automobile steering wheel, which has the following beneficial effects:

[0017] This automotive steering wheel output shaft welding mold uses a first handwheel to drive the rotation of a double-threaded screw, which allows the moving seat and mold base to open and close synchronously. After the output shaft is inserted into the clamping mold, it is clamped by closing the mold for welding. When the welding angle needs to be adjusted, the turntable can be rotated to drive the rotation of the shaft and the clamping mold. This allows for one-time welding of the circumferential angle of the output shaft without disassembling the clamping mold and the output shaft. Completing the welding in one clamp ensures consistency and repeatability in the welding process, improves the quality of the output shaft weld joint, and reduces the number of times the fixture has physical contact with the output shaft surface, thus reducing the risk of workpiece damage caused by clamping.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] This utility model provides a technical solution: a welding mold for the output shaft of an automobile steering wheel, comprising a base 1, a mounting seat 2, a slide groove 3, an assembly insert 4, a bearing 5, a double-threaded screw 6, a moving seat 7, a mold base 8, a first handwheel 9, a rotating shaft 10, a clamping mold 11, a turntable 12, a clamping groove 13, a screw 14, a pressure plate 15, a limit bolt 16, a lever 17, and a second handwheel 18.

[0026] Please see Figure 1 The top of the base 1 is equipped with a mounting base 2, please refer to [link / reference]. Figure 2 The mounting base 2 has a groove 3 in the middle of its interior, and an assembly block 4 is inserted in the middle of the groove 3. A bearing 5 is inserted inside the assembly block 4.

[0027] The double-tooth lead screw 6 is inserted inside the bearing 5. The sliding groove 3 has movable seats 7 inserted on both the left and right sides. The left and right ends of the double-tooth lead screw 6 pass through the interior of the movable seats 7. The bottom of the sliding groove 3 and the movable seats 7 are both trapezoidal. The left and right ends of the sliding groove 3 are both through-cut. The width of the movable seats 7 is one-quarter of the width of the sliding groove 3.

[0028] Please see Figure 1 Mold base 8 is mounted on top of movable base 7. Please refer to [link / reference]. Figure 3 Each mold base 8 has a rotating shaft 10 inserted inside. A clamping mold 11 is coaxially mounted on the inner end of each rotating shaft 10. A turntable 12 is coaxially connected to the left end of the left rotating shaft 10. Please refer to [link / reference]. Figure 2 The left end of the double-threaded screw 6 is coaxially equipped with a first handwheel 9. The threads on the left and right sides of the double-threaded screw 6 are set in opposite directions. The length of the double-threaded screw 6 is greater than that of the mounting base 2. The outer middle position of the mounting base 2 is connected to the inner ring of the bearing 5. The rotation of the double-threaded screw 6 is driven by the first handwheel 9, so that the moving base 7 and the mold base 8 can perform synchronous opening and closing movements. After the output shaft is inserted into the clamping mold 11, it can be clamped by closing the mold and then welded. When it is necessary to adjust the welding angle, the rotating turntable 12 can be rotated to drive the rotating shaft 10 and the clamping mold 11 to rotate. This facilitates the one-time welding of the circumferential angle of the output shaft without disassembling the clamping mold 11 and the output shaft. The one-time clamping and welding can ensure the consistency and repeatability of the welding process, improve the quality of the output shaft weld joint, and reduce the number of physical contacts between the fixture and the output shaft surface, which can reduce the risk of workpiece damage caused by clamping.

[0029] Please see Figure 4 Each clamping mold 11 has a clamping groove 13 in the middle of its interior. A screw 14 is screwed onto the top of each clamping mold 11 at the center of each clamping groove 13. A pressure plate 15 is mounted on the bottom of each screw 14 via a ball bearing. Rotating the screw 14 causes the pressure plate 15 to move up and down, thus clamping the output shaft after it is inserted into the clamping mold 11, preventing movement when the clamping mold 11 closes. Please refer to [link to relevant documentation]. Figure 5 The turntable 12 is equipped with levers 17 on its outer circumference. There are 3-6 sets of levers 17. Limiting bolts 16 are screwed onto the inner and outer sides of the turntable 12. A second handwheel 18 is coaxially installed on the left end of the limiting bolt 16. By rotating the limiting bolt 16, its right end can contact the left side of the mold base 8, thereby restricting the rotation of the turntable 12. This prevents the turntable 12 and the rotating shaft 10 from moving again after rotating to the corresponding angle, thus improving the stability of the welding after adjustment.

[0030] This solution uses the first handwheel 9 to drive the rotation of the double-threaded screw 6, thereby enabling the moving seat 7 and the mold base 8 to open and close synchronously. This allows the output shaft to be inserted into the clamping mold 11, clamped by closing the mold, and then welded. When the welding angle needs to be adjusted, the rotating turntable 12 can be rotated to drive the rotating shaft 10 and the clamping mold 11. This facilitates the one-time welding of the output shaft's circumferential angle without disassembling the clamping mold 11 and the output shaft. Completing the welding in one clamp ensures consistency and repeatability in the welding process, improving the weld joint of the output shaft. This improves the quality of the workpiece and reduces the number of times the fixture makes physical contact with the output shaft surface, thus reducing the risk of workpiece damage caused by clamping. Furthermore, rotating the screw 14 causes the pressure plate 15 to move up and down, allowing the output shaft to be clamped after being inserted into the clamping mold 11, preventing movement when the clamping mold 11 closes. Rotating the limiting bolt 16 allows its right end to contact the left side of the mold base 8, thereby limiting the rotation of the turntable 12. This prevents the turntable 12 and the rotating shaft 10 from moving again after rotating to the corresponding angle, improving the stability of the weld after adjustment.
