[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] See also Figure 1-Figure 4 The utility model provides a technical solution: a switching guide wheel mechanism for an automobile production line, comprising a slide rail 1, a blocking plate 2, a groove 201, a positioning hole 202, a spring 203, a positioning pin 1 204, a positioning pin 205, a clamping plate 206, a sleeve 207, a support frame 3 and a motor 4. The support frame 3 is placed on the top of the slide rail 1, and the blocking plate 2 is installed at the four corners of the top of the support frame 3. The clamping plate 206 is installed on the left side of the blocking plate 2, and the groove 2 is opened on the right side of the blocking plate 2. 01, positioning holes 202 are opened on the left and right sides of the groove 201, and a positioning pin 205 is inserted into the positioning hole 202, and a card slot is opened on the left and right sides of the left wall surface of the groove 201, and a connecting hole is opened at the bottom of the card slot to connect with the positioning pin 1 204, the bottom of the spring 203 is connected to the outside of the positioning pin 205, a card plate 206 is placed in the groove 201, and the left surface of the card plate 206 is connected to the sleeve 207, and the right end of the slide rail 1 is connected to the motor 4.

[0021] As the first embodiment of the utility model: the left side surface of the card plate 206 is connected to the top of the sleeve 207 with hooks on both sides, and the hooks are connected to the fixing hooks on the top of the spring 203. The design can pull the card plate 206 into the inside of the groove 201 under the action of the spring 203. The width and length of the groove 201 are greater than the width and length of the card plate 206, and the height of the inside of the groove 201 is greater than the height of the card plate 206. The design allows the outside of the card plate 206 to be connected to the inside of the groove 201. The sleeve 207 is connected to the left side surface of the card plate 206 by welding. This design plays a role in fixing the sleeve 207. The diameter of the locating pin 205 is smaller than the diameter of the inner ring of the sleeve 207. This design allows the card plate 206 to swing back and forth inside the groove 201. Two groups of screw holes are opened inside the blocking plate 2, and two groups of internal threads are opened at the four corners of the top of the support frame 3.

At this time, the bottom of the car wheel will be connected to the card plate 206. The sleeve 207 connected to the left surface of the card plate 206 is inserted into the groove 201 by the positioning pin 205. Under the gravity of the car, the card plate 206 will make the rubber pad on the surface of the card plate 206 connected to the outside of the tire, so that the car wheel plays a fixing role to prevent The wheel of the car rotates automatically. When the wheel of the car is separated from the blocking plate 2, the spring 203 will pull the clamping plate 206 back to the inside of the groove 201 by its own properties. The bottom of the spring 203 is fixed to the inside of the groove 201 by an interlaced positioning pin 204, so that the spring 203 has a better pulling force on the clamping plate 206, so that the clamping plate 206 and the groove 201 are perfectly combined. This design prevents the wheel of the car from transmitting, ensures that the wheel of the car has better stability during installation, and prevents it from separating from the support frame 3, thereby improving safety.
