Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mechanical processing, in particular to a polishing device for a polished rod. Background Art
[0002] In the field of modern industrial production, the accuracy and durability of mechanical components are one of the key factors to ensure the efficient operation of the overall equipment. As an indispensable part of various mechanical equipment, the performance of the mechanical seal system is directly related to the stability and safety of the equipment. Especially in those working environments that need to withstand high pressure, high temperature or corrosive media for a long time, the reliability of mechanical seals is particularly important. In order to ensure the effectiveness of mechanical seals, the surface finish of the connecting rod components is a crucial parameter, because it directly affects the tightness and life of the seal.
[0003] Although traditional mechanical processing techniques, such as grinding and polishing, can provide certain surface treatment effects, these methods are gradually showing their limitations in today's pursuit of higher precision and surface quality. Especially when processing slender metal rods with a large aspect ratio, existing polishing equipment often has difficulty in applying force evenly, resulting in uneven polishing, low efficiency, and easy deformation or excessive wear of the workpiece, increasing production costs and reducing material utilization. In addition, traditional polishing processes rely heavily on manual operations, which is not only time-consuming and labor-intensive, but also difficult to ensure consistency and repeatability of processing, which is a major bottleneck for large-scale production.
[0004] Although there are many automated or semi-automated polishing equipment on the market, they generally have problems such as complex equipment, high cost, and difficult maintenance. Although some equipment can improve polishing efficiency, they still have deficiencies in finish control and fine processing, especially for workpieces of special shapes or materials, it is difficult to achieve the ideal polishing effect. Utility Model Content
[0005] The utility model aims to provide a polishing device for a polished rod, which can reduce material loss during processing, improve processing efficiency, and facilitate maintenance and cost control while ensuring that the surface of a metal rod reaches a high degree of smoothness.
[0006] To achieve the above purpose, the utility model is implemented through the following technical solutions:
[0007] A polishing device for a polished rod comprises a fixing frame, and a bearing, a ball and a polishing panel which are sequentially installed on the fixing frame from the inside to the outside;
[0008] The bearing is rotatably mounted in the fixed frame body via the mounting shaft; the ball is mounted on the fixed frame via the polishing panel, and the ball is rotatably mounted in the polishing panel, with one side of the ball protruding out of the polishing panel and the other side abutting against the moving ring of the bearing.
[0009] Furthermore, a rubber pad is provided between the polishing panel and the fixing frame. The rubber sealing pad prevents metal powder from entering the gap around the metal ball, which would hinder the rotation of the metal ball.
[0010] Furthermore, a steel pad is provided between the rubber pad and the fixing frame to enhance the strength of the rubber sealing pad and prevent the deformation of the rubber pad from causing the entry of metal powder.
[0011] Furthermore: the polishing panel and the fixing frame are fixed by bolts.
[0012] Furthermore: the bolt is a five-point socket bolt.
[0013] Furthermore: the installation shaft is threadedly connected to the fixing frame.
[0014] Further: one end of the mounting shaft is provided with a mounting shaft bolt head, and the mounting shaft bolt head is a bolt head with an inner five-point angle.
[0015] Furthermore: the bearing is a deep groove ball bearing.
[0016] Compared with the original technology, the utility model has the following beneficial effects:
[0017] 1. When the ball is squeezed by the rotating polished rod, the ball is tightly connected to the outer ring of the bearing, so that the ball can squeeze the polished rod while rotating, and the surface of the polished rod is extruded and polished. This polishing method consumes the least and has a higher processing finish.
[0018] Second, the ball can rotate along with the surface of the polished rod while squeezing the polished rod, thus preventing the spherical surface from being worn and affecting the surface polish of the rod.
[0019] 3. The device has a simple design, fewer parts, and a simple shape. The materials used are easy to obtain, which not only reduces the manufacturing cost, but also facilitates daily maintenance and quick replacement of parts, reduces downtime, and improves production efficiency. It is particularly suitable for internal self-maintenance of enterprises and flexible response to different production needs. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0030] like Figure 1 As shown: a polishing device for a polished rod 10, comprising a fixing frame 1, and a bearing 2, a ball 6 and a polishing panel 5 which are sequentially mounted on the fixing frame 1 from the inside to the outside;
[0031] The bearing 2 is rotatably mounted in the frame of the fixed frame 1 via the mounting shaft 3; the ball 6 is mounted on the fixed frame 1 via the polishing panel 5, and the ball 6 is rotatably mounted in the polishing panel 5, with one side of the ball 6 protruding from the polishing panel 5 and the other side abutting against the moving circle of the bearing 2.
[0032] A rubber pad 7 is provided between the polishing panel 5 and the fixing frame 1, and a steel pad 4 is provided between the rubber pad 7 and the fixing frame 1. The polishing panel 5 and the fixing frame 1 are fixed by bolts, and the bolts are inner pentagonal bolts 8. The mounting shaft 3 is threadedly connected to the fixing frame 1, and one end of the mounting shaft 3 is provided with a mounting shaft bolt head 9, which is also an inner pentagonal bolt head. The bearing 2 is a deep groove ball bearing.
[0033] The working principle of the utility model is as follows:
[0034] The polished rod 10 to be polished is clamped on the rotating fixture of the machine tool, and the device is installed on the traveling fixture of the machine tool through the fixed frame 1. The polishing panel 5 is parallel to the axis of the polished rod 10. After the knife is aligned, the ball 6 contacts and squeezes the cylindrical surface of the polished rod 10.
[0035] Then start the machine tool. When the ball 6 contacts the cylindrical surface of the polished rod 10, the polished rod 10 is polished by squeezing the cylindrical surface of the polished rod 10. In this process, the rotating polished rod 10 drives the ball 6 to rotate through the surface friction. The outer ring of the bearing 2 is pressed against the ball 6 in the fixed frame 1, and the outer ring of the bearing 2 is the moving ring, so that the ball 6 rotates with the polished rod 10. This structural design can prevent the spherical surface of the stationary ball 6 from being worn, thereby affecting the surface polishing of the rod.
[0036] After a period of working time, the spherical surface of the ball 6 is worn and it is necessary to replace the ball 6. At this time, the polishing panel 5 can be easily removed by the inner five-point bolt 8 to replace the ball 6.
[0037] The above implementation is only to illustrate the technical concept and features of the utility model, and its purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly, and it cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
