Description

Technical Field

[0001] This utility model relates to the field of grinding and polishing machines for spring production, specifically a grinding and polishing machine for spring production. Background Technology

[0002] In the field of spring manufacturing, the quality and performance of springs are of paramount importance. The smoothness and consistency of the spring surface directly affect its performance and lifespan. During the production process, defects such as burrs and unevenness often appear on the spring surface. These defects not only affect the appearance of the spring but may also lead to problems such as accelerated wear and stress concentration during use, thereby reducing the reliability and service life of the spring. Therefore, polishing the spring surface is an indispensable and crucial step in the spring manufacturing process. Traditional eddy current polishing machines rely primarily on the free rolling and sliding between the abrasive and the workpiece for polishing. However, due to the lack of active guidance and control during the polishing process, the abrasive struggles to effectively penetrate the gaps between spring coils and the internal channels. These special structural parts of the spring are often "dead zones" in traditional eddy current polishing, resulting in these areas not being fully polished. This, in turn, affects the overall surface quality and performance consistency of the spring. Furthermore, when processing multiple springs, traditional eddy current polishing machines lack effective isolation and fixing mechanisms, causing the springs to easily become entangled and knotted during the eddy current motion. This entanglement and knotting not only increases the difficulty and workload of subsequent processing but may also cause the springs to deform during collisions, resulting in impact damage. This severely affects the precision and quality of the springs, reduces the product qualification rate, and increases production costs. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide a grinding and polishing machine for spring production, so as to solve the technical problems of grinding and polishing machines for spring production.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a grinding and polishing machine for spring production, comprising an installation mechanism, wherein the installation mechanism includes an installation frame, and an agitation mechanism is provided on the upper sides of both sides of the installation frame; The agitation mechanism includes an electric actuator. The top of the electric actuator is detachably connected to a mounting head and a fixed frame is attached to it. The fixed frame and the mounting head are fixedly connected by bolts. Four swing motors are provided at the bottom of the fixed frame, and agitation rods are provided at the output ends of the four swing motors.

[0005] By adopting the above technical solution, the installation mechanism includes a mounting frame and a stirring mechanism on both sides above, providing basic support and structural frame for the grinding and polishing machine, clarifying the positional relationship of each component, making the overall structure reasonable and orderly, which is conducive to the subsequent installation of components and the development of grinding and polishing operations.

[0006] Furthermore, the four swing motors are divided into two groups, with two swing motors in each group, and the two groups of swing motors are mirror images of each other along the central axis of the fixed frame.

[0007] By adopting the above technical solution, the four swing motors are arranged in two groups and mirrored along the central axis of the fixed frame, which can generate symmetrical and balanced stirring force, making the abrasive more evenly distributed around the spring, improving the uniformity of grinding and polishing, and ensuring that the grinding and polishing effect of each part of the spring is consistent.

[0008] Furthermore, the bottom of the mounting bracket is provided with multiple casters, which are arranged in a rectangular array at equal intervals.

[0009] By adopting the above technical solution, the bottom of the mounting frame is equipped with multiple universal wheels arranged in a rectangular array at equal intervals, which facilitates the flexible movement and positioning of the grinding and polishing machine. The equipment position can be quickly adjusted according to production needs, thereby improving production efficiency and site utilization.

[0010] Furthermore, a polishing mechanism is rotatably connected to the inner side of the mounting frame via a bearing, and an adjustment motor is provided on the lower side of one side of the mounting frame, with the output end of the adjustment motor passing through the mounting frame and fixedly connected to the polishing mechanism.

[0011] By adopting the above technical solution, the polishing mechanism is rotatably connected to the inner side of the mounting frame via bearings, and an adjustment motor is installed on one side below and fixedly connected to it, which allows the polishing mechanism to rotate flexibly. The adjustment motor can precisely control the rotation angle and speed to meet different polishing requirements.

[0012] Furthermore, the polishing mechanism includes a polishing groove, a rotating disk is rotatably connected inside the polishing groove, and a column is provided at the top axis of the rotating disk.

[0013] By adopting the above technical solution, the polishing mechanism has a rotating disk in the polishing groove and a column at the top axis.

[0020] In summary, the present invention has the following main advantages: This invention incorporates a stirring mechanism, in which the electric actuator of the stirring mechanism can flexibly adjust the height of the fixed frame to accommodate the polishing needs of springs of different specifications. Four swing motors are mirror-imaged along the central axis of the fixed frame, divided into two groups. The stirring rods connected to their output ends can actively swing. In traditional eddy current polishing machines, the abrasive and workpiece mainly rely on free rolling and sliding for grinding, resulting in a highly random motion trajectory. However, this invention, by adding actively swinging rods, introduces directional and controllable scraping and stirring effects into the eddy current field during the polishing process. In principle, the swing motors drive the stirring rods to swing rhythmically. During its oscillation, the stirring rod exerts a directional force on the surrounding abrasive and spring. This force guides the abrasive to move along a specific direction and path, forming a composite motion mode. This composite motion mode is completely different from the traditional grinding method that relies solely on the free rolling and sliding of the abrasive. It forces the abrasive to enter the gaps and internal channels between the spring coils more effectively. Traditional eddy current grinding, due to the lack of active guidance, makes it difficult for the abrasive to reach these special structural parts, resulting in grinding dead angles. This design of the present invention successfully solves this problem, greatly improving the overall surface quality and performance consistency of the spring. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] A grinding and polishing machine for spring production, such as Figure 1-4 As shown, it includes an installation mechanism 1, which includes a mounting frame 101, and a stirring mechanism 3 is provided on the upper sides of both sides of the mounting frame 101. The agitation mechanism 3 includes an electric actuator 301. A fixed frame 303 is detachably connected to the top of the electric actuator 301 via a mounting head 302, and the fixed frame 303 is bolted to the mounting head 302. Four swing motors 304 are installed at the bottom of the fixed frame 303, and agitation rods 305 are installed at the output ends of the four swing motors 304. The mounting frame 101 in the mounting mechanism 1 serves as the core support structure, with the agitation mechanism 3 positioned above and on both sides. This layout forms the basic frame of the polishing machine. The mounting frame 101 provides stable mounting positions for other components, ensuring the stability of the entire equipment structure. The agitation mechanism 3 is positioned specifically to facilitate coordinated work with subsequent polishing mechanisms, creating a reasonable spatial layout among the components of the polishing machine. This allows each component to function effectively during the polishing process, ensuring that the polishing operation is carried out in an orderly and efficient manner.

[0025] See Figure 1 The four swing motors 304 are divided into two groups, with two motors in each group. The two groups of swing motors 304 are mirror images of each other along the central axis of the fixing frame 303. This unique layout is significant. During the polishing process, the agitation forces generated by the two groups of swing motors 304 are symmetrical and balanced, ensuring a more uniform distribution of abrasive around the spring. Uneven agitation forces prevent abrasive accumulation or loss in certain areas, thus guaranteeing uniform polishing of all parts of the spring. This effectively improves the uniformity of polishing, resulting in more consistent overall surface quality and performance of the spring, and increasing the product yield.

[0026] See Figure 1 , Figure 4 The mounting frame 101 has multiple casters 105 arranged in a rectangular array at equal intervals at its bottom. This arrangement greatly facilitates the movement of the polishing machine. The equidistant rectangular array ensures the stability of the casters 105 when supporting the mounting frame 101, allowing the equipment to remain stable during movement. During production, the polishing machine can be moved quickly and flexibly and accurately positioned according to different production needs, such as changing production sites or adjusting the relative positions of the equipment with upstream and downstream processes. This significantly improves production efficiency, avoids time wastage caused by difficulties in equipment movement, and also increases the utilization rate of site resources.

[0027] See Figure 4 The polishing mechanism 2 is rotatably connected to the inner side of the mounting frame 101 via bearings. An adjusting motor 106 is located on the lower side of one side of the mounting frame 101, with its output end passing through the mounting frame 101 and fixedly connected to the polishing mechanism 2. This connection allows the polishing mechanism 2 to rotate flexibly. The adjusting motor 106, fixedly connected to the polishing mechanism 2, provides power and control for the rotation of the polishing mechanism. The adjusting motor 106 can precisely control the rotation angle and speed of the polishing mechanism 2, flexibly adjusting its working state according to different spring specifications and polishing process requirements. For example, for springs of different diameters, the rotation angle can be adjusted to allow the abrasive to better contact the spring surface; the rotation speed can be adjusted to control the polishing force and efficiency, thereby meeting diverse polishing needs.

[0028] See Figure 3 , Figure 4 The polishing mechanism 2 includes a polishing groove 201, with a rotating disk 203 rotatably connected inside the polishing groove 201. A column 204 is positioned at the top axis of the rotating disk 203. This structural design plays a crucial role in the polishing mechanism 2. The column 204 can be used to fix the spring, ensuring its stable position during the polishing process and preventing it from moving arbitrarily. The rotating disk 203 rotates under the drive of a servo motor, causing the spring fixed on the column 204 to rotate as well. During rotation, the abrasive can fully and comprehensively contact all surfaces of the spring, including the sides and end faces, ensuring effective polishing of all parts of the spring. This significantly improves the polishing effect and guarantees the uniformity of the spring's surface quality.

[0029] See Figure 1 , Figure 2A servo motor 202 is installed at the bottom of the polishing trough 201. The output end of the servo motor 202 passes through the polishing trough 201 and is fixedly connected to the rotating disk 203, providing crucial power for the rotation of the rotating disk 203. The servo motor 202 has precise control performance and can stably drive the rotating disk 203 to rotate according to preset parameters, such as speed and direction. During the polishing process, this precise control ensures that the rotating disk 203 operates according to the set requirements, keeping the relative motion between the spring and the abrasive stable, thereby ensuring the stability and efficiency of the polishing process. This avoids problems such as uneven polishing or low polishing efficiency caused by unstable power, improving the polishing quality.

[0030] See Figure 1 , Figure 4 Both the polishing groove 201 and the rotating disk 203 have raised strips arranged in a circular array at equal intervals on their inner walls. This design has a positive impact on the polishing process. During polishing, the raised strips increase the friction between the abrasive and the spring. When the rotating disk 203 drives the spring to rotate, the raised strips ensure closer and more thorough contact between the abrasive and the spring surface, allowing the abrasive to better grind and polish the spring surface. This enhanced friction allows burrs, oxide layers, and other impurities on the spring surface to be removed more effectively, improving the surface finish of the spring. Simultaneously, the evenly distributed raised strips ensure uniform polishing, avoiding polishing quality problems caused by insufficient or excessive local friction, thus comprehensively improving the polishing quality.

[0031] See Figure 3 , Figure 4 On the other side of the mounting frame 101, below the control panel 102, a control console 103 is mounted. The control panel 104 is angled on the outer surface of the control console 103. This design fully considers the actual needs of the operators. The angled control panel 104 allows operators to more easily observe various indicator lights and displays while standing or sitting, and also provides more comfortable button operation. The control console 103 is securely mounted on the mounting frame 101 via the control panel 102, ensuring the stability of the control components during equipment operation. This design improves production convenience, allowing operators to quickly and accurately set parameters and control the grinding and polishing machine, while also reducing potential safety accidents caused by operational inconvenience and improving production safety.

[0032] The implementation principle of this embodiment is as follows: First, the grinding and polishing machine can be easily moved to the designated working position by means of multiple universal wheels 105 arranged in a rectangular array at equal intervals at the bottom of the mounting frame 101, which provides convenience for subsequent operations; Next, using the telescopic function of the electric push rod 301, the mounting head 302 is connected to the fixed frame 303 by bolts, and the fixed frame 303 is adjusted to a suitable height to meet the production needs of springs of different specifications. Since the four swing motors 304 are divided into two groups and mirrored along the central axis of the fixed frame 303, the stirring rod 305 at its output end can swing actively. During the grinding and polishing process, the swing motor drives the stirring rod to swing regularly, generating a directional force, guiding the abrasive to move in a specific direction and path, forming a compound motion mode, so that the abrasive can effectively enter the gaps and internal channels between the spring coils, solving the problem of dead angles in traditional grinding. Simultaneously, the adjusting motor 106 drives the polishing mechanism 2 to rotate, the servo motor 202 at the bottom of the polishing groove 201 drives the rotating disk 203 to rotate, the column 204 at the top of the rotating disk 203 can help fix the spring, the raised strips on the inner wall of the polishing groove 201 and the rotating disk 203 can enhance the friction between the abrasive and the spring, and improve the polishing effect. Finally, the operator can set parameters and operate the polishing machine through the control panel 104 on the control frame 102 which is set at an angle, so as to realize the efficient polishing production of springs.
