Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing equipment technology, and specifically discloses a wear-resistant coating spraying device for a new type of automotive starter armature shaft. Background Technology

[0002] In the production process of automotive starter armature shafts, a wear-resistant coating is typically applied to the shaft surface to improve its wear resistance. However, traditional spraying equipment has several shortcomings in practical use: First, existing spraying equipment struggles to ensure uniform coating coverage of the entire armature shaft surface. This is because the armature shaft lacks an effective multi-dimensional rotation mechanism during spraying, resulting in some areas not being fully covered by the nozzle (due to the armature shaft's single fixed posture, the coating thickness difference between its axial middle section and end exceeds 20%), or the distance between the nozzle and different parts of the armature shaft is inconsistent, leading to uneven coating thickness and severely impacting the armature shaft's wear resistance and service life. Second, traditional spraying equipment has low efficiency. It generally uses a sequential spraying method for individual armature shafts, and the clamping, positioning, and adjustment of the workpiece during spraying consume a significant amount of time, making it difficult to meet the demands of large-scale production. Utility Model Content

[0003] This invention proposes a wear-resistant coating spraying device for a new type of automotive starter armature shaft. Through the coordinated operation of a suspension assembly combining revolution and rotation, an adjustable-angle fan-shaped nozzle, and a lifting spraying mechanism, a uniform and efficient wear-resistant coating is achieved on the armature shaft. It also has the beneficial effects of quick clamping, adaptability to different shaft lengths, and reduced paint waste.

[0004] This utility model is implemented as follows: a wear-resistant coating spraying device for a new type of automotive starter armature shaft, comprising a base, a spraying mechanism, and a shelf; the spraying mechanism includes a paint tank, a bracket, a lifting slide, a linear lifting device, and a nozzle fixed on the base; the bracket has a T-shaped structure, and the lifting slide is slidably mounted on the bracket; the linear lifting device is fixed to the top of the bracket, and its telescopic end is connected to the lifting slide; the nozzle is connected to the paint tank through a pipe and is fixed on the side of the lifting slide away from the paint tank; The shelf includes a ring support base, a rotating platform, and three suspension components; the ring support base is fixed to the base by a support column; the rotating platform is rotatably mounted inside the ring support base by a bearing; the three suspension components are evenly distributed circumferentially at the bottom of the rotating platform. The annular support is equipped with a revolution motor, the output end of which meshes with the gear ring at the top of the rotating platform through a gear pair; the rotating platform is equipped with a self-rotation motor, which drives the suspension assembly to rotate around its own axis.

[0005] As a preferred embodiment of the wear-resistant coating spraying device for a novel automotive starter armature shaft according to the present invention, the suspension assembly includes a drive seat rotatably connected to the bottom of the rotating platform via a bearing, a lifting frame fixed to the bottom of the drive seat, and a suspension hook provided at the end of the lifting frame, the suspension hook being used to attach the top hanging ring of the armature shaft.

[0006] In a preferred embodiment of this invention, a wear-resistant coating spraying device for a novel automotive starter armature shaft is provided, wherein the output end of the self-rotating motor is driven to connect with the drive seat.

[0007] As a preferred embodiment of the wear-resistant coating spraying device for a novel automotive starter armature shaft according to this utility model, the gear pair includes a drive gear fixed to the output end of a revolution motor, and the drive gear meshes with a gear ring.

[0008] As a preferred embodiment of the wear-resistant coating spraying device for a new type of automobile starter armature shaft according to the present invention, the linear lifting device is an electric push rod or a servo cylinder, whose extension and retraction stroke covers the axial length of the armature shaft. The nozzle is an angle-adjustable fan-shaped nozzle, and its spray direction is toward the radial center of the suspension assembly to achieve full coverage spraying of the armature shaft surface.

[0009] As a preferred embodiment of the wear-resistant coating spraying device for a new type of automobile starter armature shaft according to the present invention, the lifting slide is a rectangular frame structure, and the vertical part of the bracket slides through the interior of the lifting slide.

[0010] The beneficial effects of this utility model are: 1. By rotating the platform and the suspension components, the armature shaft can pass under the nozzle with similar motion trajectories during the spraying process. At the same time, the up and down movement of the nozzle effectively solves the problem of uneven coating in traditional devices, significantly improves coating uniformity, and thus enhances the wear resistance and service life of the armature shaft.

[0011] 2. The shelf is equipped with multiple suspension components, which can suspend multiple armature shafts for spraying at the same time. Compared with the traditional method of spraying one at a time, it greatly improves the spraying efficiency and can meet the needs of large-scale production. In addition, the structure of each part of the device is reasonably designed, and the clamping, positioning and adjustment operations are simple, which further shortens the spraying time of a single armature shaft and improves the overall work efficiency.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0018] Please see Figure 1-3 A wear-resistant coating spraying device for a novel automotive starter armature shaft includes a base 1, a spraying mechanism 2, and a shelf 3. The spraying mechanism 2 includes a paint tank 4, a bracket 5, a lifting slide 6, a linear lifting device 7, and a nozzle 8, all fixed to the base 1. The bracket 5 has a T-shaped structure, and the lifting slide 6 is slidably mounted on the bracket 5. The linear lifting device 7 is fixed to the top of the bracket 5, and its telescopic end is connected to the lifting slide 6. The nozzle 8 is connected to the paint tank 4 through a pipe and is fixed to the side of the lifting slide 6 away from the paint tank 4. The shelf 3 includes an annular support base 9, a rotating platform 10, and three suspension components 11; the annular support base 9 is fixed to the base 1 by a support column 12; the rotating platform 10 is rotatably mounted in the annular support base 9 by a bearing; the three suspension components 11 are evenly distributed around the bottom of the rotating platform 10. A revolution motor 13 is provided on the annular support 9. The output end of the revolution motor 13 meshes with the gear ring 14 on the top of the rotating platform 10 through a gear pair. A self-rotating motor 15 is provided on the rotating platform 10. The self-rotating motor 15 is used to drive the suspension assembly 11 to rotate around its own axis.

[0019] In this embodiment: In the shelf 3, the annular support base 9 provides a fixed support foundation for the overall rotating structure. The revolution motor 13 installed on it serves as a power source. Through the output end of the drive gear 19, it meshes with the gear ring 14 at the top of the rotating platform 10, driving the rotating platform 10 to revolve stably around the central axis of the annular support base 9. This drives the three suspension components 11 evenly distributed around the bottom of the platform to revolve synchronously, so that the armature shaft attached to the suspension hook 18 obtains a circumferential motion trajectory. At the same time, the self-rotation motor 15 on the rotating platform 10 directly drives the drive seat 16 of the suspension component 11 to rotate around its own axis. Through the hoisting frame 17, the power is transmitted to drive the armature shaft to rotate autonomously. Under the dual motor drive, the armature shaft completes both revolution and rotation at the same time, ensuring that each area of ​​the shaft surface can approach the nozzle 8 at a consistent angle and frequency, avoiding the spraying dead angle caused by the single fixed posture of traditional equipment. In the spraying mechanism 2, the vertical part of the bracket 5 provides a stable sliding guide for the lifting slide 6. The linear lifting device 7 is fixed to the top of the bracket 5, and its telescopic end is connected to the lifting slide 6. It can precisely control the movement stroke of the lifting slide 6 according to the axial length of the armature shaft. The nozzle 8 is fixed on the side of the lifting slide 6 away from the paint tank 4, and the spraying direction is towards the radial center of the suspension assembly 11. It can move smoothly in the vertical direction with the lifting slide 6. With the rotational movement of the armature shaft, the nozzle 8 can completely cover the entire axial length of the armature shaft under the premise of continuous material supply from the paint tank 4, ensuring that every part of the shaft surface can be uniformly sprayed, solving the problem of uneven axial coating thickness caused by the fixed nozzle 8 in traditional methods.

[0020] As a technical optimization of this utility model, the suspension assembly 11 includes a drive seat 16 rotatably connected to the bottom of the rotating platform 10 via a bearing, a hoisting frame 17 fixed to the bottom of the drive seat 16, and a suspension hook 18 located at the end of the hoisting frame 17. The suspension hook 18 is used to attach the top hanging ring of the armature shaft.

[0021] In this embodiment: it helps to improve the stability and reliability of the armature shaft suspension, thereby ensuring the stable rotation of the armature shaft during the spraying process; the suspension hook 18 is S-shaped, with one end hanging on the hanging hole on the hoisting frame 17, and the other end used to hang the top hanging ring of the armature shaft.

[0022] As a technical optimization of this utility model, the output end of the self-rotating motor 15 is driven to be connected to the drive base 16.

[0023] In this embodiment: the self-rotating motor 15 is started to ensure that the self-rotating motor 15 can effectively drive the drive seat 16 to rotate, thereby realizing the rotation of the armature shaft and providing a guarantee for uniform spraying.

[0024] As a technical optimization of this utility model, the gear pair includes a drive gear 19 fixed to the output end of the revolution motor 13, and the drive gear 19 meshes with the gear ring 14.

[0025] In this embodiment: the revolution motor 13 is started, and the power of the revolution motor 13 is transmitted to the rotating platform 10 to realize its revolution. The effect is to ensure that the rotating platform 10 can perform the revolution movement stably and accurately, so that the armature shaft can receive uniform spraying during the revolution.

[0026] As a technical optimization of this utility model, the linear lifting device 7 is an electric push rod or a servo cylinder, and its extension stroke covers the axial length of the armature shaft. The nozzle 8 is an angle-adjustable fan-shaped nozzle, and its spray direction is toward the radial center of the suspension assembly 11 to achieve full coverage spraying of the armature shaft surface.

[0027] In this embodiment, the nozzle 8 is guaranteed to move up and down precisely according to the length of the armature shaft, and the fan-shaped nozzle can spray the coating evenly onto the surface of the armature shaft, thereby improving the uniformity and quality of the coating.

[0028] As a technical optimization of this utility model, the lifting slide 6 is a rectangular frame structure, and the vertical part of the bracket 5 slides through the inside of the lifting slide 6.

[0029] In this embodiment, the structure of the lifting slide 6 and its cooperation with the bracket 5 ensure that the sliding of the lifting slide 6 on the bracket 5 is more stable, thereby improving the smoothness of the lifting movement of the nozzle 8, which is beneficial to improving the accuracy and quality of spraying.

[0030] Working principle and usage process of this utility model: The armature shaft to be painted is attached to the suspension hook 18 of the suspension assembly 11 via the top hanging ring; at this time, the output end of the self-rotating motor 15 is connected to the drive seat 16, preparing for the subsequent rotation of the armature shaft; the revolution motor 13 is turned on, and its output drive gear 19 meshes with the gear ring 14 at the top of the rotating platform 10, driving the rotating platform 10 to begin revolution within the annular support seat 9; simultaneously, the self-rotating motor 15 is turned on, and the drive seat 16 rotates around its own axis under the drive of the self-rotating motor 15, thereby driving the armature shaft to rotate; the linear lifting device 7 is activated, and the extension and retraction end of the electric push rod or servo cylinder drives the lifting slide 6 along... The support 5 moves vertically; since the nozzle 8 is fixed on the side of the lifting slide 6 away from the paint tank 4, the nozzle 8 moves up and down accordingly; the nozzle 8 is an angle-adjustable fan-shaped nozzle, and its spraying direction is towards the radial center of the suspension assembly 11 to achieve full coverage spraying of the armature shaft surface. During the movement, the paint in the paint tank 4 is evenly sprayed onto the surface of the armature shaft; when the linear lifting device 7 completes one stroke, covering the entire axial length of the armature shaft, and the armature shaft is fully sprayed on all parts of the surface under the combined action of revolution and rotation, the equipment is turned off, the sprayed armature shaft is removed, and one spraying operation is completed.
