Description

Technical Field

[0001] This invention relates to the field of automotive technology, and in particular to a clamping fixture for surface treatment of automotive steering wheel frames. Background Technology

[0002] During the manufacturing process of car steering wheels, die casting is used. Die casting is a method of casting by pressing molten metal into a mold under high pressure. Since die casting relies on the fluidity of the liquid, burrs and die casting marks will appear on the surface of the product during the liquid flow die casting process. Therefore, the die-cast car steering wheels need to be polished to ensure that the outer surface of the car steering wheel is smooth, which will facilitate subsequent painting and other operations.

[0003] A clamping fixture for surface treatment of automotive steering wheel frame, with application number CN202421145828.1, can adapt to automotive steering wheels of different sizes and is easy to install. However, in actual use, it has been found that because the steering wheel is clamped and fixed, only the upward side is convenient for deburring. When treating the downward side, the steering wheel needs to be reversed, which leads to low work efficiency. In addition, the clamped position is obstructed, and some defects need to be processed again, making it inconvenient to use. Summary of the Invention

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] Example

[0025] A clamping fixture for surface treatment of automotive steering wheel frames includes a load-bearing base 1, with a servo motor inside. The output end of the servo motor is fixedly connected to a worktable 2. Electromagnetic slide rails 3 are symmetrically arranged on the worktable 2. Connecting seats 4 are fixedly mounted on the sliders of the electromagnetic slide rails 3. The connecting seats 4 are connected to support plates 5 via pins. One support plate 5 is fixedly equipped with a drive clamping assembly 6, and the other support plate 5 is fixedly equipped with a driven cleaning clamping assembly 7. The automotive steering wheel is clamped by the drive clamping assembly 6 and the driven cleaning clamping assembly 7. During the clamping process, the steering angle of the support plates 5 can be manually adjusted to ensure that the drive clamping assembly 6 and the driven cleaning clamping assembly 7 are tightly clamped to the steering wheel. The positions of the drive clamping assembly 6 and the driven cleaning clamping assembly 7 can be changed by the electromagnetic slide rails 3 to clamp various sizes of round automotive steering wheels, thus expanding the applicability. When it is necessary to change the working surface of the automotive steering wheel, the servo motor drives the entire worktable 2 to rotate, making the working surface of the automotive steering wheel easy and quick to adjust.

[0026] The drive clamping assembly 6 includes a drive bending base plate 61. Both sides of the drive bending base plate 61 are connected to drive clamping arc-shaped side plates 62 via rotating assemblies 64. Several drive assemblies 63 are evenly distributed on the drive bending base plate 61. When clamping the car steering wheel, the car steering wheel is made to fit against the drive bending base plate 61, and the side of the car steering wheel is clamped and fixed by the drive clamping arc-shaped side plates 62, thereby fixing the car steering wheel.

[0027] The drive assembly 63 includes a small motor 631, which is connected to a mobile terminal via an electrical signal. The control end of the small motor 631 is fixedly connected to the side of the drive bending base plate 61, and the output end of the small motor 631 is fixedly connected to the drive arc wheel 632. Part of the drive arc wheel 632 is located inside the drive bending base plate 61, and part of it is located on the upper surface of the drive bending base plate 61. The outer surface of the drive arc wheel 632 is provided with a rubber layer.

[0028] As the small motor 631 starts, it drives the drive arc wheel 632 to rotate. The drive arc wheel 632 pushes the car steering wheel to rotate, exposing the clamped part of the car steering wheel, which is convenient for quick processing of the clamped part. When working on the car steering wheel, the car steering wheel is fixed by its own weight and the friction between the rubber layer and the car steering wheel, ensuring that the car steering wheel will not rotate during operation.

[0029] The driven cleaning clamping assembly 7 includes a cleaning curved base plate 71, which has two sides connected to cleaning clamping arc-shaped side plates 72 via a rotating assembly 64. A cleaning arc-shaped wheel 73 is rotatably connected to the upper surface of the cleaning curved base plate 71. Part of the cleaning arc-shaped wheel 73 is located inside the cleaning curved base plate 71, and part is located on the upper surface of the cleaning curved base plate 71. The outer surface of the cleaning arc-shaped wheel 73 is provided with soft bristles.

[0030] After the driving clamping assembly 6 completes the car steering wheel clamping operation, the position of the driven cleaning clamping assembly 7 can be changed by the electromagnetic slide rail 3 and the steering angle of the support plate 5 can be manually adjusted so that the car steering wheel is attached to the cleaning curved base plate 71. When the driving clamping assembly 6 drives the car steering wheel to rotate, the cleaning arc wheel 73 can clean the car steering wheel. And when the car steering wheel is fixed, the friction between the soft bristles and the steering wheel is used to fix the steering wheel.

[0031] The rotating assembly 64 includes a rotating groove 641, a positioning post 642 is fixedly connected to the center of the partition block between the rotating grooves 641, a connecting block 644 is rotatably connected to the positioning post 642, and a rotation spring 643 is provided between the connecting block 644 and the positioning post 642.

[0032] In its natural state, the rotary spring 643 drives the drive clamping arc-shaped side plate 62 and the cleaning clamping arc-shaped side plate 72 to clamp the car steering wheel, ensuring stable clamping and adapting to clamping car steering wheels of different thicknesses.

[0033] The drive clamping arc-shaped side plate 62 and the cleaning clamping arc-shaped side plate 72 are provided with a number of evenly distributed balls 8. When the car steering wheel is driven to rotate, the balls 8 provide rolling force to ensure that the steering wheel rotates smoothly.

[0034] Both the servo motor and the electromagnetic slide rail 3 are connected to the mobile terminal via electrical signals, and are controlled by the mobile terminal, saving manpower and improving the degree of automation.

[0035] Working principle:

[0036] As shown in the figure, during use, the electromagnetic slide rail 3 is controlled by a mobile terminal to move the drive clamping assembly 6 and the driven cleaning clamping assembly 7. The steering angle of the adjustment support plate 5 is manually adjusted. These two methods are used to adjust the clamping position of the car steering wheel, so that the car steering wheel is stably clamped on the drive clamping assembly 6 and the driven cleaning clamping assembly 7. After clamping is completed, the operation on the car steering wheel begins. After the operation on the unclamped part of the car steering wheel is completed, the small motor 631 is started by controlling the mobile terminal to drive the drive arc wheel 632 to rotate. The drive arc wheel 632 pushes the car steering wheel itself to rotate. While the car steering wheel is rotating, the cleaning arc wheel 73 cleans the already operated part. The operation on one side of the car steering wheel is completed. When it is necessary to change the side, the servo motor is controlled by the mobile terminal to drive the worktable 2 to rotate as a whole to adjust the working surface of the car steering wheel.

[0037] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
