Description

Technical Field

[0001] This utility model relates to the field of armature shaft manufacturing technology, and specifically discloses a coating device for an automotive starter armature shaft. Background Technology

[0002] As a core component of the starter motor, the armature shaft of an automotive starter motor requires impregnation with insulating varnish to improve the electrical insulation, corrosion resistance, and mechanical strength of the windings. Traditional impregnation processes typically involve fixed impregnation or manual operation, where the armature shaft is left to soak in the varnish bath before being removed and drained. However, this method suffers from uneven varnish film thickness, edge buildup, or missed areas, affecting product performance and reliability.

[0003] Most existing dipping coating equipment uses fixed clamps to hold the armature shaft, which is difficult to adapt to the processing requirements of different shaft diameters and lacks an effective rotary coating mechanism, resulting in uneven paint flow and defects such as bubbles or sagging after curing. Therefore, a dipping coating device for automotive starter armature shafts is needed to solve this problem. Utility Model Content

[0004] This invention proposes a paint impregnation device for automotive starter armature shafts. The device uses synchronously rotating rollers to ensure uniform paint impregnation of the armature shaft and employs an adjustable-gap scissor-type telescopic frame to adapt to armature shafts of different specifications, thus solving the problems of uneven coating and poor versatility in traditional paint impregnation processes.

[0005] This utility model is implemented as follows: a paint impregnation device for an automotive starter armature includes a housing containing paint. The outer wall of the housing is equipped with a paint impregnation mechanism. The paint impregnation mechanism includes a bracket fixedly connected to the upper surface of the housing. A gantry frame is mounted on the lower side of the bracket via a lifting mechanism. Multiple evenly distributed movable blocks are arranged on the lower side of the gantry frame. The middle movable block is fixedly connected to the gantry frame, while the remaining movable blocks are movably connected to the gantry frame. Scissor-type telescopic frames are movably connected to the outer walls of the multiple movable blocks. A first rotating shaft is rotatably connected to the lower inner side of each movable block. Both ends of the first rotating shaft extend to the outside of the movable block and are fixedly connected to rollers. The inner... A hexagonal shaft is rotatably connected to the wall. A servo motor with its output end fixedly connected to the hexagonal shaft is installed on the outer wall of the portal frame. A sleeve that is slidably connected to the hexagonal shaft is rotatably connected through a bearing inside the movable block. A first bevel gear is fixedly connected to the outer wall of the sleeve. A mounting plate is fixedly connected to the upper side inside the movable block. A second rotating shaft is rotatably connected through a bearing on the outer wall of the mounting plate. A second bevel gear that meshes with the first bevel gear is fixedly connected to one side of the outer wall of the second rotating shaft. A first pulley is fixedly connected to the other side of the outer wall of the second rotating shaft. A second pulley is fixedly connected to the outer wall of the first rotating shaft. The first pulley and the second pulley are connected by a belt drive. A threaded rod is rotatably connected between the inner walls of the portal frame, and through holes are provided on the outer walls of the multiple movable blocks for the threaded rod to pass through. A threaded sleeve that is threadedly connected to the threaded rod is fixedly connected to the inner wall of the through hole at the edge.

[0006] As a preferred embodiment of the automotive starter armature impregnation device of this utility model, the lifting mechanism includes an electric push rod mounted on the upper end face of the bracket, and the output end of the electric push rod is fixedly connected to the gantry frame.

[0007] As a preferred embodiment of the automotive starter armature impregnation device of this utility model, the upper end face of the gantry frame is fixedly connected with two limiting rods that are slidably connected to the bracket.

[0008] As a preferred embodiment of the automotive starter armature impregnation device of this utility model, the lower end of the outer wall of the housing has a paint drain port with a valve on the outer wall.

[0010] As a preferred embodiment of the automotive starter armature impregnation device of this utility model, a controller is provided on the outer wall of the housing, and the electric push rod and the servo motor are both electrically connected to the controller.

[0011] The beneficial effects of this utility model are: 1. By using a servo motor to drive a hexagonal shaft to synchronously rotate multiple rollers, the armature shaft rotates at a uniform speed during the varnishing process, ensuring that the varnish adheres evenly to the surface of the armature shaft. This avoids problems such as uneven coating thickness, dripping, or bubbles caused by traditional fixed varnishing methods, thereby improving the insulation performance and durability of the armature shaft.

[0012] 2. The scissor-type telescopic frame, combined with the threaded rod adjustment mechanism, allows for flexible adjustment of the distance between adjacent rollers to accommodate armature shafts of different diameters, reducing equipment replacement frequency and improving production efficiency and equipment utilization.

[0024] In this embodiment: the armature shaft to be dipped in paint is placed on two adjacent roller shafts 7 respectively, the servo motor 9 is started, the servo motor 9 drives the hexagonal shaft 8 to rotate, which in turn drives multiple sleeves 10 to rotate synchronously, the sleeves 10 further drive the first bevel gear 11 to rotate, which in turn drives the second bevel gear 14 to rotate, the second bevel gear 14 further drives the second rotating shaft 13 to rotate, which in turn drives the first pulley 15 to rotate, the first pulley 15 further drives the second pulley 21 to rotate through the belt, which in turn drives the first rotating shaft 6 to rotate, the first rotating shaft 6 further drives the roller shaft 7 to rotate, which in turn drives the armature shaft to rotate, so that the paint is evenly coated on the armature shaft; Rotating the threaded rod 16 causes the movable block 5 on the edge to move via the threaded sleeve 17, which in turn causes the other movable blocks 5 to move synchronously via the scissor-type telescopic frame 18. This adjusts the distance between adjacent rollers 7 to accommodate armature shafts of different diameters. This invention can drive the armature shaft to rotate, solving the problem of uneven paint coating caused by the previous fixed armature shaft. It can also adjust the distance between two adjacent rollers 7 according to the specifications of the armature shaft, making it highly practical.

[0035] The working principle and usage process of this utility model are as follows: In use, firstly, adjust the distance between the two rollers 7 according to the specifications of the armature shaft. Specifically, rotate the threaded rod 16, which drives the movable block 5 on the edge through the threaded sleeve 17. This, in turn, drives the remaining movable blocks 5 to move synchronously through the scissor-type telescopic frame 18, thereby adjusting the distance between adjacent rollers 7. Then, place the armature shaft to be dipped in paint on the two adjacent rollers 7 respectively. Start the servo motor 9, which drives the hexagonal shaft 8 to rotate, thereby driving multiple sleeves 10 to rotate synchronously. The sleeves 10 further drive... The rotation of the first bevel gear 11 drives the rotation of the second bevel gear 14, which in turn drives the rotation of the second shaft 13, which in turn drives the rotation of the first pulley 15.
