Description
Technical Field
[0001] This utility model relates to the field of mandrel production and processing technology, and in particular to a multifunctional surface treatment device for mandrel production and processing. Background Technology
[0002] A mandrel is a tool used in various industrial manufacturing processes. In pipe production, it is inserted into the pipe and, in conjunction with an external mold, determines the pipe's inner diameter and shape, and assists in pipe forming, ensuring uniform wall thickness. It also plays a similar supporting and shaping role in some metal processing or composite material molding processes.
[0003] When this device is working, the automatic feeding mechanism first sends the mandrel to the processing area. The grinding module uses a high-speed rotating abrasive to contact the mandrel. The abrasive grinder grinds the surface of the mandrel according to a preset path and force, making the surface gradually flat and smooth. Then, the subsequent process further processes it, thereby achieving the initial processing of the mandrel surface.
[0004] In existing technologies, some surface treatment devices for mandrel production and processing experience increased friction between the mandrel and the grinding wheel during use, which leads to reduced grinding efficiency, accelerated grinding wheel wear, and increased costs. Furthermore, without lubrication and cooling, the mandrel surface may experience localized deformation and other quality problems due to overheating. Therefore, a multifunctional surface treatment device for mandrel production and processing is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a multifunctional surface treatment device for mandrel production and processing, which aims to improve the problem in the prior art that it is no longer possible to spray lubricating oil on the surface of the mandrel while grinding it, which would lead to deformation of the grinding tools and the mandrel.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0023] 1. In this utility model, the eccentric wheel is driven to rotate by starting the motor. When the eccentric wheel rotates, it can drive the connecting block to move. When the connecting block moves, it can move the slide rod fixed on the connecting block. This can effectively reduce the friction between the grinding wheel and the mandrel, improve grinding efficiency, reduce grinding wheel wear, and at the same time, the lubricating oil can carry away the heat generated by grinding and prevent the mandrel surface from overheating and deforming.

This not only protects the internal components of the equipment from dust corrosion, but also reduces the probability of failure and extends the service life of the equipment.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a multifunctional surface treatment device for mandrel production and processing, including an operating machine 1, which is a machine capable of processing mandrels. The top of the operating machine 1 is fixedly connected to a supply component for providing lubricant to the mandrel. The supply component includes an oil storage tank 2, the bottom of which is fixedly connected to the top of the operating machine 1. The oil storage tank 2 serves as a storage container for lubricant, and its bottom is firmly fixed to the top of the operating machine 1. A pump 3 is fixedly connected to the right side of the oil storage tank 2. The pump 3, which is closely connected to the right side of the oil storage tank 2, plays a key role in extracting the lubricant from the oil storage tank 2. A diversion pipe 4 is fixedly connected to the output end of the pump 3. The diversion pipe 4 is responsible for diverting and transporting the extracted lubricant. Telescopic pipes 5 are fixedly connected to both ends of the diversion pipe 4, allowing the lubricant to be transferred to the interior of the telescopic pipe 5 through the diversion pipe 4.
[0033] A motor 6 is fixedly connected to the top of the manipulator 1. An eccentric wheel 7 is fixedly connected to the drive end of the motor 6. Under the drive of the motor 6, a specific motion trajectory is generated. A push rod 8 is slidably connected to the bottom of the eccentric wheel 7. This connection method allows the motion of the eccentric wheel 7 to be converted into the linear motion of the push rod 8. A positioning rod 9 is fixedly connected to the top of the manipulator 1. A slide rod 10 is slidably connected to the bottom of the positioning rod 9. The positioning rod 9 at the top of the manipulator 1 provides a stable guide for the motion of the slide rod 10. The end of the slide rod 10 away from the positioning rod 9 is fixed. The connecting block 11 is connected to the inside of the push rod 8, which is slidably connected to the outside of the connecting block 11. The connecting block 11 and the push rod 8 form a nested sliding connection, which allows the slide rod 10 to move left and right under the drive of the push rod 8. The left and right sides of the slide rod 10 away from the positioning rod 9 are fixedly connected to the nozzles 12. These two nozzles 12 are the final spray points of the lubricant and can achieve the effect of reciprocating spraying. The other ends of the two telescopic tubes 5 are fixedly connected to the outside of the nozzles 12, ensuring that the lubricant can be smoothly delivered to the inside of the nozzles 12.
[0034] The left end of the manipulator 1 is fixedly connected to a second motor 13. The drive end of the second motor 13 is fixedly connected to a rotating shaft 14. The second motor 13 can make the rotating shaft 14 rotate. Two grinding discs 15 are fixedly connected to the outside of the rotating shaft 14. The rotating shaft 14 can make the grinding discs 15 grind the mandrel. Multiple stop pulleys 16 are fixedly connected inside the manipulator 1. A transmission shaft 17 is rotatably connected inside the manipulator 1. The stop pulleys 16 and the transmission shaft 17 can realize the function of transporting and positioning the mandrel.
[0035] Reference Figure 2 and Figure 3 A cleaning assembly for cleaning dust from the core rod is fixedly connected to the outside of the rotating shaft 14. The cleaning assembly includes a drive wheel 18, which is fixedly connected to the outside of the rotating shaft 14. The rotating shaft 14 can drive the drive wheel 18 to rotate. A belt 19 is sleeved on the outside of the drive wheel 18, which can drive the belt 19 to transmit power. A linkage rod 20 is rotatably connected to the bottom of the manipulator 1. One end of the linkage rod 20 near the motor 13 is fixedly connected to a driven wheel 21. When the driven wheel 21 rotates, it can drive the linkage rod 20 to rotate. The other end of the belt 19 is sleeved on the outside of the driven wheel 21, and the belt 19 can transmit power to the driven wheel 21. A fixing ring 22 is fixedly connected to the outside of the linkage rod 20. When the linkage rod 20 rotates, it can drive the fixing ring 22 to rotate.
[0036] A push rod 23 is fixedly connected to the outside of the fixed ring 22. A displacement rod 24 is rotatably connected to the other end of the push rod 23, so that the fixed ring 22 drives the push rod 23 and the displacement rod 24 to move. A push plate 25 is rotatably connected to the end of the displacement rod 24 away from the push rod 23. When the displacement rod 24 moves, it can drive the push plate 25 to move. Limiting blocks 26 are fixedly connected to both ends of the push plate 25. A sliding groove 27 is opened at the bottom of the inside of the operating machine 1. A parallel rod 28 is fixedly connected inside the sliding groove 27. The inside of the limiting block 26 is slidably connected to the outside of the parallel rod 28. The movement position of the limiting block 26 can be controlled by the parallel rod 28, so that the movement of the limiting block 26 is linear. The bottom of the push plate 25 is slidably connected to the inside of the operating machine 1. The push plate 25 can clean the dust inside the operating machine 1. Through these functions, the automatic conveying, positioning, lubrication and dust cleaning of the mandrel can be achieved.
[0037] Working principle: When the mandrel needs to be polished, it is first placed near the end of the stop pulley 16 and the transmission shaft 17. Since the transmission shaft 17 rotates, the stop pulley 16 can provide resistance and assist in sliding. At this time, the pump 3 draws lubricant from the oil tank 2 and then transfers the lubricant to the distribution pipe 4, allowing the distribution pipe 4 to transfer the lubricant to the two telescopic pipes 5. Then, the motor 6 drives the eccentric wheel 7 to rotate. As the eccentric wheel 7 rotates, it drives the connecting block 11 to move. As the connecting block 11 moves, the sliding rod 10 fixed on the connecting block 11 moves. The slide bar 10 can move back and forth, which in turn allows the nozzle 12 to move back and forth. The positioning rod 9 can limit the movement of the slide bar 10. At this time, the lubricant inside the telescopic tube 5 is transmitted to the nozzle 12, so that the nozzle 12 can spray the lubricant back and forth on the surface of the mandrel. In this way, it can be ensured that the mandrel is lubricated by the lubricant before grinding, and will not deform due to overheating before processing. Secondly, the mandrel can move between the stop pulley 16 and the transmission shaft 17. The rotating shaft 14 driven by the motor 13 can drive the two grinding discs 15 to rotate, thereby grinding the mandrel. Then, it is transmitted from both sides of the manipulator 1.
[0038] After grinding, debris is generated, which needs to be cleaned off. The rotation of the shaft 14 fixed by the motor 13 drives the externally fixed drive wheel 18 to rotate, which in turn drives the externally sleeved belt 19 to transmit power to the driven wheel 21. The driven wheel 21 then drives the internally fixed linkage rod 20 to rotate, which in turn causes the fixed ring 22 to rotate. As the fixed ring 22 rotates, it drives the push rod 23 to move forward. As the push rod 23 moves forward, it pushes the displacement rod 24 forward, which in turn drives the push plate 25 to move forward, thus cleaning the debris inside the manipulator 1. As the push plate 25 moves, it drives the limiting block 26 to move. The limiting block 26 can move outside the parallel rod 28, thus restricting the movement of the push plate 25 and maintaining its stability during movement. Through these functions, the automatic conveying, positioning, lubrication, and dust removal of the mandrel during grinding can be achieved.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
