DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1 , Figure 2 As shown, the utility model provides a locking device for a steering wheel skeleton of an automobile, comprising a welding platform mechanism 1, a skeleton positioning mechanism 2 is fixedly installed on the top of the welding platform mechanism 1, the skeleton positioning mechanism 2 comprises a fixing bracket 21, the fixing bracket 21 is fixedly installed on the top of the welding platform mechanism 1, a rotating motor 22 is fixedly installed on the rear side of the fixing bracket 21, the output shaft of the rotating motor 22 penetrates to the front side of the fixing bracket 21 and is fixedly installed with a triangular positioning frame 23, three inclined surfaces of the inner circle of the triangular positioning frame 23 are fixedly installed with arc plates 25, the tops of the three arc plates 25 are clamped with a steering wheel skeleton 27, infrared transmitters 24 are fixedly installed on the upper and lower surfaces of the triangular positioning frame 23 close to the output shaft of the rotating motor 22, grooves are provided on the three inclined surfaces at the top of the triangular positioning frame 23, and locking mechanisms 26 are fixedly installed in the three grooves;

[0021] By starting the rotating motor 22 on the rear side of the fixed bracket 21, the entire triangular positioning frame 23 is driven to flip over. When the infrared signal generated by the infrared transmitter 24 on the top of the triangular positioning frame 23 is received by the infrared receiver 12 directly opposite the top of the welding platform 11, the rotating motor 22 can be automatically powered off, so that the triangular positioning frame 23 completes a 180-degree flip, thereby placing the unwelded portion of the bottom side of the steering wheel skeleton 27 upwards to facilitate welding.

[0022] like Figure 3 As shown, the three locking mechanisms 26 all include a locking box 261, and the tops of the three locking boxes 261 are all fixedly installed with electric push rods 262, and the output ends of the three electric push rods 262 all penetrate into the inner cavity of the locking box 261 and are fixedly installed with hanging plates 263, and the three locking boxes 261 are all provided with a slide groove 264 that penetrates into the inner cavity on one side near the center of the triangular positioning frame 23, and the ends of the three hanging plates 263 near the center of the triangular positioning frame 23 penetrate the slide groove 264 and are fixedly installed with arc-shaped clamping plates 265, and the three arc-shaped clamping plates 265 are respectively located above the three arc-shaped plates 25;

[0023] During processing, the wheel rim of the steering wheel skeleton 27 is placed on the top of the arc plate 25 on the three inclined surfaces of the inner circle of the triangular positioning frame 23, and then the electric push rods 262 on the top of the three locking boxes 261 are started at the same time, thereby driving the hanging plate 263 to slide downward in the slide groove 264, so that the three arc-shaped clamps 265 clamp and lock the upper surface of the wheel rim.

[0024] like Figure 4 , Figure 5 As shown, the welding platform mechanism 1 includes a welding platform 11, an infrared receiver 12 is fixedly installed on the top rear side of the welding platform 11, and the infrared receiver 12 is located below the infrared transmitter 24. A placement hole 13 is opened on the top of the welding platform 11 and passes through to the bottom. The inner circle of the placement hole 13 is provided with a skeleton supporting mechanism 14, and the skeleton supporting mechanism 14 includes a connecting plate 141. The front and rear sides of the connecting plate 141 are respectively fixedly connected to the front and rear sides of the inner wall of the placement hole 13. A driving box 142 is fixedly installed at the bottom of the connecting plate 141, and a lifting motor 143 is fixedly installed at the bottom of the inner wall of the driving box 142. A lifting threaded rod 144 is fixedly installed at the output end of the lifting motor 143, and a lifting plate 145 is threadedly installed on the outer wall of the lifting threaded rod 144. The four sides of the lifting plate 145 overlap the four sides of the inner wall of the driving box 142. Connecting rods 146 are fixedly installed on both the front and rear sides of the top of the lifting plate 145. The top ends of the two connecting rods 146 penetrate to the top of the connecting plate 141 and are fixedly installed with a supporting plate 147. Clamps 148 are fixedly installed in a triangular direction around the center of the top of the supporting plate 147. Arc-shaped air bags 149 are fixedly installed on one side of the three clamps 148 close to the center of the supporting plate 147.

[0025] By placing the wheel hub and the spoke part on the top of the supporting plate 147, the three clamping plates 148 can use the arc-shaped airbags 149 to clamp the wheel hub at the center position. The arc-shaped airbags 149 can be used to improve the stability during clamping. At the same time, the three spokes can extend out using the gaps between the three clamping plates 148, and then the lifting motor 143 at the bottom of the inner wall of the driving box 142 can be driven to drive the lifting threaded rod 144 to rotate, so that the lifting plate 145 can move upward using the threaded connection with the lifting threaded rod 144, and the connecting rod 146 can be used to lift the entire supporting plate 147 until it moves to the inner ring of the wheel rim locked and fixed by the steering wheel skeleton 27, and then the connection between the spoke and the wheel rim can be welded. After welding, the output shaft of the lifting motor 143 can be driven again to reverse, so that the supporting plate 147 moves down and retracts until it stops when it contacts the top of the connecting plate 141 between the front and rear sides of the inner wall of the placement hole 13, thereby reserving sufficient space for the flipping of the triangular positioning frame 23.

[0026] The working principle of the automobile steering wheel skeleton locking device will be specifically described below.

[0027] like Figure 1-5 As shown, during processing, the wheel rim of the steering wheel skeleton 27 is placed on the top of the arc plate 25 on the three inclined surfaces of the inner circle of the triangular positioning frame 23, and then the electric push rods 262 on the top of the three locking boxes 261 are started at the same time, thereby driving the hanging plate 263 to slide downward in the slide groove 264, so that the three arc-mouth clamping plates 265 clamp and lock the upper surface of the wheel rim. At this time, the wheel hub and the spoke part are placed on the top of the supporting plate 147, and the three clamping plates 148 can use the arc-shaped airbags 149 to clamp the wheel hub at the center position. At the same time, the three spokes extend out using the gaps between the three clamping plates 148, and then the lifting motor 143 at the bottom of the inner wall of the driving box 142 can be driven to drive the lifting threaded rod 144 to rotate, so that the lifting plate 145 is moved upward by using the threaded connection with the lifting threaded rod 144, and the connecting rod 146 is used to lift the whole The supporting plate 147 is lifted up until it moves to the inner ring of the wheel rim locked and fixed by the steering wheel skeleton 27, and then the welding can be carried out on the connection between the spoke and the wheel rim. After welding, the output shaft of the lifting motor 143 can be driven to reverse again, so that the supporting plate 147 moves down and retracts until it stops when it touches the top of the connecting plate 141 between the front and rear sides of the inner wall of the placement hole 13. Then, the rotating motor 22 on the rear side of the fixed bracket 21 can be started to drive the overall triangular positioning frame 23 to flip. When the infrared signal generated by the infrared transmitter 24 on the top of the triangular positioning frame 23 is received by the infrared receiver 12 facing the top of the welding platform 11, the rotating motor 22 can be automatically powered off, so that the triangular positioning frame 23 completes a 180-degree flip, thereby placing the unwelded part of the bottom side of the steering wheel skeleton 27 facing upwards, which is convenient for welding.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
