Description

Technical Field

[0001] The utility model relates to an electric stopping device, belonging to the technical field of automobile assembly production lines. Background Art

[0002] Track docking conveying is one of the commonly used conveying methods in automobile assembly production lines. At present, the existing stoppers in China include pneumatic stoppers. The working principle of the pneumatic stopper is: the cylinder drives the connecting rod to make the blocking rod reciprocate, thereby realizing the stopping action of the workpiece. The pneumatic stopper requires additional air circuit components for the aerial conveyor line. In order not to lay out the air circuit components on the aerial conveyor line, an electric stopper is often used. The electric stopper includes a reduction motor, and the reduction motor drives the blocking block to move through the cam assembly, so that only the rotation output of the reduction motor needs to be controlled to stably realize the stopping function of the trolley on the conveyor line. At present, the blocking block on the electric stopper is a part of the rotating arm, that is, when the blocking part on the electric stopper blocks and stops the trolley on the conveyor line, the relative position of the blocking part on the electric stopper and the trolley cannot be adjusted. For trolleys of different sizes, it is easy for the blocking part on the electric stopper to not contact the middle area on the side of the trolley, so that the trolley is subjected to uneven force when it is blocked and stopped. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model aims to provide an electric stopping device to solve the problems raised in the above-mentioned background technology. The utility model can adjust the relative position of the blocking part and the trolley according to the size of the trolley.

[0004] The cam is connected with the gear train of the motor to move the gear train to the drive means, the cam being connected with the gear train by the drive means, and the cam being connected with the gear train by the drive means.

[0005] Further, one end of the stud is fixedly connected with a threaded head, a threaded hole is machined in the middle position of the surface of the stud away from the reverse threaded head, and the threaded head on one stud is threadedly connected in the threaded hole on another stud.

[0006] Further, a position switch is provided on the side of the lower support plate away from the blocking block, and the position switch is fixedly connected with the carrier plate.

[0007] Further, the carrier plate is fixedly connected with the bracket, and the bracket is of a U-shaped structure.

[0008] Further, a contact head is provided on the side surface of the blocking block away from the lower support plate, a plugging rod is fixedly connected to the surface of the contact head facing the blocking block, a plugging groove penetrating through the blocking block is formed in the area of the blocking block covered by the contact head, the plugging rod is inserted in the plugging groove, a countersunk head screw hole is formed in the lower surface of the blocking block, and a positioning screw for restricting the plugging rod in the plugging groove is threadedly connected in the countersunk head screw hole.

[0009] Further, the cross section of the plugging rod is rectangular, and the cross section of the plugging groove is rectangular.

[0010] Advantages of the utility model:

[0011] 1. Adjust the distance between the blocking block and the rotating arm. At this time, the distance between the upper support plate and the lower support plate changes. Insert the stud into the channel formed by the upper round hole and the lower round hole, and screw the first nut and the second nut on both sides of the stud respectively. Furthermore, the structure formed by the two groups of first nuts, second nuts and studs realizes the restriction of the relative position between the blocking block and the rotating arm, which is convenient to adjust the relative position between the blocking block and the rotating arm according to the size of the trolley, so that the blocking block can contact the middle position of the side surface of the trolley, preventing the trolley from being unevenly stressed when being blocked.

[0012] 2. Screw the threaded head on one stud into the threaded hole on another stud to complete the assembly of two adjacent studs, and so on, to complete the mutual assembly of multiple studs, which is convenient to select the corresponding number of studs according to the maximum distance between the blocking block and the rotating arm, without using studs with longer lengths.

[0013] 3. Insert the plugging rod on the contact head into the plugging groove, adjust the length of the plugging rod in the plugging groove, so that the distance between the contact head and the blocking block changes. When the distance between the blocking block and the contact head meets the requirements, use the positioning screw to restrict the relative position between the contact head and the blocking block. Since the size of the contact head is smaller than that of the blocking block, it is convenient for the structure formed by the blocking block and the contact head to contact the recessed part on the side surface of the trolley.
