Description

Technical Field

[0001] The invention belongs to the technical field of machining tools, and in particular relates to a device and method for machining a rotating shaft of an automobile steering wheel. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] In the automotive parts manufacturing industry, steering wheel shafts are key components. Traditional processing equipment for these components uses either a clamping method with jaws or multiple stamping processes on a punch press to form them. With the clamping method, the uneven distribution of the clamping force can lead to unstable clamping for thin tubular parts. This can cause the workpiece to vibrate or shift during processing, resulting in reduced processing accuracy and increased product scrap rates. A punch press is used to perform three stamping processes to form the parts. This method not only has low processing efficiency but also requires multiple positioning and clamping steps, resulting in large cumulative errors and difficulty in ensuring dimensional accuracy. Furthermore, most existing stamping equipment is single-function and lacks precise control and flexible adjustment capabilities. This makes it difficult to achieve precise processing of complex shapes such as escape hatches, making it impossible to meet the increasingly diverse product demands and further leading to high processing costs. Summary of the Invention

[0004] In response to the above problems, the present invention provides a device and method for processing automobile steering wheel shaft parts, which utilizes a pin shaft in combination with a spring tightening mechanism instead of clamping with a clamping claw, thereby solving the problem that traditional processing devices are unstable in clamping thin tubular parts and are difficult to adapt to the processing of workpieces of different sizes, and achieves stable clamping of workpieces of different specifications; the design of the annular groove of the welding slag pin shaft effectively avoids the problem that the pipe fitting cannot be completely cut off, replaces the three-step stamping process of the punch press, and performs forming through one-time cutting process, thereby reducing production costs.

When installing the workpiece 7, the positioning notch at one end of the workpiece 7 fits tightly with the directional pin 25 of the workpiece 7 to achieve circumferential positioning of the other end of the workpiece 7, ensuring that the workpiece 7 does not rotate during the processing; the welding slag pin shaft 15 is connected to the installation shaft 24, and an annular groove 26 is provided on its surface.

Specifically, when the workpiece 7 is installed in place, the clamping die 13 is in close contact with the other end of the workpiece 7; an elastic element 12 is installed between the clamping die 13 and the linear bearing 10. When the movable pin 11 is pushed to make the clamping die 13 contact the workpiece 7, the elastic element 12 is compressed to generate elastic force, pushing the movable pin 11 to press the workpiece 7 in a suitable position; a handle 14 is set at the other end of the movable pin 11, and the operator can manually operate the handle 14 to conveniently control the movement of the movable pin 11, thereby achieving the tightening or loosening of the workpiece 7.

At the same time, the limit groove on its top guides and limits the movable slider, ensuring that the movable slider can only move along the length direction of the track housing 19, thereby ensuring the accuracy and stability of the movement of the drive device 3.

Specifically, when the moving slider moves on the track housing 19, the baffles 18 on both sides will move with the slider; when the baffle 18 blocks the light emitted by the photoelectric sensor 22, the photoelectric sensor 22 will generate a signal change. By detecting and processing these signals, the specific position of the moving slider on the track housing 19 can be accurately determined; it can effectively avoid the situation where the moving slider exceeds the predetermined stroke due to the continuous operation of the screw drive mechanism, thereby damaging the workpiece 7 or the equipment.

[0042] As a further implementation method, a baffle plate 18 is provided at one end of the track housing 19 close to the fixed bracket 23, which is used to prevent welding slag from falling onto the horizontal positioning plate 2 during the laser cutting process, and to prevent serious accumulation from affecting the movement of the movable slider; the baffle plate 18 can block the welding slag from falling toward the horizontal positioning plate 2, and prevent the welding slag from accumulating on the horizontal positioning plate 2; once a large amount of welding slag accumulates on the horizontal positioning plate 2, it may affect the normal movement of the movable slider on the track housing 19, and even damage the movable slide rail 4 components. The setting of the baffle plate 18 effectively protects the movable slide rail 4 and the horizontal positioning plate 2.

[0043] As a further implementation method, height adjustment parts are provided at the four corners of the horizontal positioning plate 2 for adjusting the levelness of the horizontal positioning plate 2 to avoid the horizontal positioning plate 2 from tilting due to uneven ground or other factors, thereby affecting the processing accuracy of the workpiece 7.

[0044] Example 2

[0045] This embodiment provides a working method of a vehicle steering wheel shaft processing device, comprising the following steps:

[0046] S1. The positioning notch at one end of the workpiece 7 is matched with the workpiece 7 directional pin 25 on the positioning shaft 8 to achieve circumferential positioning of the other end of the workpiece 7; the pressing die 13 is brought into contact with the other end of the workpiece 7 by moving the pin 11, and the elastic element 12 is compressed to generate elastic force to press and fix the workpiece 7; at the same time, the height of the floating tightening device 6 can be appropriately adjusted on the fixing bracket 23 according to the actual situation of the workpiece 7 through the waist holes on both sides of the positioning seat 9 and the fasteners;

[0047] S2. The servo motor 20 is started, driving one gear in the double-gear mechanism 21 fixedly connected thereto to rotate. Through the gear meshing transmission, the other gear drives the screw of the screw drive mechanism to rotate. The screw rotation drives the movable slider to move along the limit groove at the top of the track housing 19, moving the drive device 3 and the positioning shaft 8 connected thereto to a suitable position. During the movement process, the baffles 18 on both sides of the movable slider cooperate with the photoelectric sensors 22 on both sides of the track housing 19 to accurately determine the position of the movable slider, thereby preventing the screw drive mechanism from continuously operating and causing damage to the workpiece 7.

[0048] S3. After the driving device 3 and the positioning shaft 8 move to the predetermined position, the driving device 3 drives the positioning shaft 8 to rotate, and the laser cutting head 5 moves back and forth. The waste slag generated during the cutting process falls into the annular groove 26 on the welding slag pin 15. At the same time, the shielding plate 18 at one end of the track housing 19 close to the fixed bracket 23 can prevent the welding slag from falling onto the horizontal positioning plate 2 and accumulating, thereby affecting the movement of the movable slider.

[0049] S4. After the workpiece 7 is cut, the handle 14 of the floating clamping device 6 is manually operated, and the moving pin 11 drives the clamping die 13 to release the workpiece 7.
