[0002] The steering wheel is a wheel-shaped device that controls the direction of travel of cars, ships and airplanes. Its function is to convert the force applied by the driver to the edge of the steering wheel into torque and then transmit it to the steering shaft. After the steering wheel is manufactured and formed, the outer side of the steering wheel needs to be trimmed, commonly known as grinding;

[0003] The patent document with publication number CN207616272U in the prior art provides a steering wheel skeleton trimming device, which includes an operating table, the left and right sides of the inner wall of the operating table are fixedly connected by a fixing plate, the top of the fixing plate is fixedly connected with a fixing cover, the top of the fixing cover is sleeved with a motor, the output end of the motor is fixedly connected to the bottom of the main gear, the top of the inner wall of the operating table is fixedly connected with a gearbox, the top of the main gear is fixedly connected to the input end of the gearbox through a connecting rod, and the output end of the gearbox is fixedly connected to the bottom end of the rotating rod. By using the motor, the main gear, the driven gear and the cutting head in coordination with each other, the main gear drives the driven wheel to rotate under the rotation of the motor, so that the cutting head can cut and grind the side surface of the steering wheel body. There are four cutting heads, which can increase the cutting speed and improve the efficiency of steering wheel production, thereby further improving the production output.

[0024] Example

[0025] See also Figure 1-Figure 5 , a trimming device for steering wheel processing shown in the figure comprises:

[0026] A driving assembly 101 is provided inside the operating table 100, and a rotating rod 110 is provided at the power output end of the driving assembly 101. The outer circumferential wall of the rotating rod 110 is matched with a fixing seat 111 fixed to the top of the operating table 100 by bolts. The rotating rod 110 runs through the top of the fixing seat 111 and the rotating rod 110 can rotate. A cutting head 112 is provided at the power output end of the rotating rod 110. A supporting frame 120 is fixed to the top of the operating table 100 by bolts, and a connecting member 121 is fixed to the side wall of the supporting frame 120 by bolts.

A sliding block 131 is slidably matched inside the limiting member 130, and an adjusting bolt 133 is provided on the side wall of the sliding block 131.

[0027] In some embodiments, the adjusting bolt 133 is rotatably connected to the side wall of the sliding block 131, and the adjusting bolt 133 cannot be separated from the side wall of the sliding block 131. When the stopper 130 is installed, the position of the sliding block 131 can be adjusted by screwing the adjusting bolt 133, so that the rotating rod 110 can be matched with the inside of the bearing 132 of the sliding block 131.

[0028] The air suction member 200 is fixed to the top of the fixing seat 111 by bolts, and a dust collecting groove 201 is provided on the top of the air suction member 200, and a connecting pipe 202 is provided at the output end of the dust collecting groove 201.

The filter screen 222 is a common stainless steel filter screen on the market, and an air suction pump 230 is provided at the output end of the dust filter 220;

[0029] In some embodiments, the suction pump 230 uses a common model on the market. The suction pump 230 is a device for extracting air or gas, usually composed of a piston, a valve and a pipe. It changes the volume by the up and down movement of the piston to generate negative pressure, thereby inhaling air or gas. The suction pump 230 is electrically connected to a common external pump machine button switch on the market.

[0030] Specifically, a partition net is provided on the top of the dust removal trough 201;

[0031] In some embodiments, the partition mesh is a common metal mesh on the market, and dust can pass through the partition mesh. When the cutting head 112 performs edge trimming and grinding operations, larger debris can fall directly into the beveled cylinder 210. When the suction pump 230 uses the dust trough 201 to extract air from the beveled cylinder 210, the dust generated by the cutting and grinding of the cutting head 112 will pass through the partition mesh and enter the dust trough 201, and then enter the interior of the dust filter 220 through the connecting pipe 202.

[0032] Furthermore, the beveled cylinder 210 is matched with the bottom of the cutting head 112 .

[0033] Furthermore, a bearing 132 is disposed inside the sliding block 131 , and the rotating rod 110 is fitted inside the bearing 132 .
