Description

Technical Field

[0001] The invention relates to the technical field of rearview mirror rod processing, in particular to a mirror rod processing production line. Background Art

[0002] The mirror rod processing process of the rearview mirror generally requires five steps, including loading, turning, thread rolling, butt welding and stamping and bending. In the whole process, the mirror rods are transported to the turning machine one by one through the loading equipment. After turning, the mirror rods are transported to the thread rolling equipment for thread processing. Then the mirror rods are transported to the butt welding machine for butt welding with the universal joint on the rearview mirror. Finally, the mirror rods are transported to the stamping equipment for stamping and bending to complete the processing of the mirror rods.

[0003] The Chinese patent with the announcement number CN211679820U discloses a thread rolling machine for the mirror rod of an electric vehicle rearview mirror, which includes a frame, a feed channel, a hopper, a centralizer, an ejection mechanism, a transmission mechanism, a pull rod, and a thread rolling plate; the frame is provided with a feed channel, the feed end of the feed channel is connected to the output end of the turning machine, the end of the feed channel is provided with a hopper, the hopper is connected to the centralizer, the centralizer is provided on the frame, and the bottom of the centralizer is telescopically provided with an ejection mechanism; the transmission mechanism is provided on the frame, the transmission mechanism is connected to the pull rod, and the pull rod performs reciprocating linear motion through the transmission mechanism; two thread rolling plates are provided on the frame, the two thread rolling plates are arranged oppositely, and the gap between the thread rolling plates is a processing position, and the processing position is located in front of the ejection mechanism; the pull rod is connected to a thread rolling plate, and the pull rod is connected to the ejection mechanism through a movable block, and the reciprocating linear motion of the pull rod is opposite to the telescopic motion direction of the ejection mechanism. The utility model improves the processing efficiency by realizing automatic feeding and processing of the mirror rod.

[0004] With regard to the above-mentioned related technologies, in the prior art, the staff uses a straightener to guide the mirror rod into between the clamping claw and the push block, and drives the push block to move the mirror rod and drop it between the two thread rolling plates to realize the thread rolling processing of the mirror rod. However, in the prior art, when the mirror rod moves, in order to ensure that the mirror rod can smoothly escape from the range of the clamping claw during the thread rolling process, the restricted range of the clamping claw cannot cover the direction in which the mirror rod is pushed, and there is no other means to limit the moving direction of the mirror rod in the prior art. This causes the mirror rod to easily deviate during the movement, and there is a possibility that the mirror rod will escape from the restricted range of the clamping claw, ultimately making it impossible for the mirror rod to smoothly reach the thread rolling station, so that the mirror rod cannot smoothly complete the thread rolling step, thereby reducing the processing efficiency of the mirror rod. Summary of the invention

[0005] In order to improve the processing efficiency of mirror rods, the present application provides a mirror rod processing production line.

[0006] The mirror rod processing production line provided in this application adopts the following technical solution:

[0008] By adopting the above technical solution, when rolling the mirror rod, the staff transports the mirror rods one by one to the turning assembly through the conveying assembly. After the mirror rods are processed by the turning assembly, they enter the moving channel. The mirror rods are pushed to the rolling gap by the pushing assembly. Then, the moving rolling plate is pushed by the reciprocating drive assembly. The mirror rods move and rotate between the moving rolling plate and the fixed rolling plate until they are separated from the fixed rolling plate. During this process, the mirror rods are cut by the helical teeth on the fixed rolling plate and the moving rolling plate, so that threads are formed on the mirror rods, achieving the effect of rolling the mirror rods. Before rolling the mirror rods, the staff use the pushing assembly to push the mirror rods to the rolling gap. The mirror rods are restricted by the moving channel during the movement, which reduces the possibility of the mirror rods being offset or tipped over, so that the mirror rods can smoothly reach the designated position and complete the rolling steps, thereby improving the processing efficiency of the mirror rods.

[0009] Optionally, the pushing assembly includes a pushing cylinder and a pushing block, the pushing block is slidably fitted on the moving channel and inserted into the moving channel, the thread rolling notch is located on the moving path of the pushing block, the pushing cylinder is also connected to the moving channel, and the output shaft of the pushing cylinder is connected to the pushing block.

[0010] By adopting the above technical solution, when pushing the mirror rod to move, the staff starts the pushing cylinder to move the push block, thereby pushing the mirror rod to move until it reaches the thread rolling notch, thereby achieving the effect of pushing the mirror rod to move.

[0016] By adopting the above technical solution, when feeding the turning tool, the staff starts the feeding motor to rotate the feeding screw rod, move the nut block, and move the tool holder, thereby achieving the effect of feeding the turning tool.

[0017] Optionally, a delivery component is provided on the frame at a position corresponding to the position between the three-jaw chuck and the moving channel, and the delivery component includes a fixed frame, a flip plate, a delivery cylinder and a limiting plate. The fixed frame is connected to the frame, and a guide plate is connected to the fixed frame. The guide plate is inclined, and the top of the guide plate is located below the three-jaw chuck. An interference step is provided at the entrance end of the moving channel.

The conveying cylinder is started, and the output shaft of the conveying cylinder pushes the bottom mirror rod to move and enter the conveying channel. The moving mirror rod pushes other mirror rods to move to the clamping station of the turning assembly, thereby achieving the effect of conveying the mirror rods one by one.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. When threading the mirror rod, the staff transports the mirror rods one by one to the turning assembly through the conveying assembly. After the mirror rods are processed by the turning assembly, they enter the moving channel. The mirror rods are pushed to the thread rolling notch by the pushing assembly. Then, the moving thread rolling plate is pushed by the reciprocating drive assembly. The mirror rods move and rotate between the moving thread rolling plate and the fixed thread rolling plate until they are separated from the fixed thread rolling plate. During this process, the mirror rods are cut by the helical teeth on the fixed thread rolling plate and the moving thread rolling plate, so that threads are formed on the mirror rods, achieving the effect of threading the mirror rods. Before threading the mirror rods, the staff uses the pushing assembly to push the mirror rods to the thread rolling notch.
