Description

Technical Field

[0001] The utility model relates to the technical field of polishing, in particular to a vibration abrasive fluid polishing device for a crankshaft. Background Art

[0002] A vibration abrasive fluid polishing device for crankshafts is specifically designed for polishing crankshaft surfaces. It primarily consists of a storage container, a circulation system, a vibration mechanism, and a control system. The storage container stores abrasive fluid, which is delivered to the crankshaft surface via the circulation system. The vibration mechanism causes the entire device to vibrate at a specific frequency and amplitude, prompting the abrasive fluid to cut and grind the crankshaft for polishing. The control system precisely adjusts vibration parameters, the flow rate of the abrasive fluid, and other parameters to ensure an efficient and stable polishing process, thereby improving the surface quality and accuracy of the crankshaft.

[0003] A search revealed a Chinese patent with publication number CN221270775U, which discloses a vibration abrasive fluid polishing device for crankshafts. The patent describes a technical solution in which a fastening assembly is rotated to drive a fixing block in conjunction with a fixing rod to secure the crankshaft body within a polishing box. An ultrasonic generator is then used in conjunction with a mixed abrasive to cause the mixed abrasive to vibrate and remove burrs from the crankshaft surface. This method utilizes ultrasonic waves in conjunction with the mixed abrasive to polish the crankshaft surface, reducing the force applied to the crankshaft surface during polishing and improving the accuracy of crankshaft machining.

[0004] In this solution, although the accuracy is greatly improved during polishing, after the abrasive fluid is used, it is only filtered through a simple screen. The structure is relatively simple, and the abrasive fluid is not screened thoroughly enough, resulting in some impurities unable to be discharged. When used for the second time, it will affect the polishing of the workpiece, thereby reducing the quality of the workpiece. In order to solve this technical problem, the utility model proposes a vibration abrasive fluid polishing device for crankshafts. Utility Model Content

[0014] (3) Beneficial effects

[0015] The utility model provides a vibration abrasive fluid polishing device for a crankshaft. It has the following beneficial effects:

[0016] (1) After the motor is started, it drives the rotating shaft to rotate, thereby rotating the cam on the rotating shaft. When the cam rotates, it repeatedly pushes the connecting block to move left and right in the slide groove. The connecting block drives the outer frame to move together. The outer frame receives the abrasive fluid through the feed port. During the movement, the elastic force of the spring on the fixed plate makes the shaking of the outer frame more regular. The screen in the outer frame screens the abrasive fluid flowing in and filters out the impurities after polishing. This combination solves some problems in the existing device. In traditional polishing devices, the abrasive fluid is often discarded directly after use, resulting in a waste of resources. This combination realizes the screening and impurity removal of the abrasive fluid, so that it can be recycled, saving resources and reducing costs. At the same time, it improves work efficiency and enhances the practicality and sustainability of the device.

[0017] (2) After the motor 3 is started, it drives the rotating column to rotate, and the rotating column further drives the crankshaft body at both ends of the connecting rod to rotate. During the rotation of the crankshaft body, the abrasive fluid and the polishing solvent in the polishing box are stirred and mixed. This combination effectively solves some problems in the existing device. In traditional polishing operations, the abrasive fluid and the polishing solvent are often mixed unevenly, resulting in poor polishing effect. However, through the cooperation of the motor 3, the rotating column and the crankshaft body, the abrasive fluid and the polishing solvent can be fully mixed, ensuring the uniformity and stability of the mixing, thereby improving the quality and efficiency of polishing. At the same time, this mechanical stirring method reduces the labor intensity and uncertainty of manual stirring, making the polishing process more controllable, and providing a reliable guarantee for high-quality polishing of small workpieces.

[0025] Embodiment 1: A vibration abrasive fluid polishing device for a crankshaft, comprising a workbench 1, a discharge port 2 is provided inside the workbench 1, a shell 3 is fixedly connected to the bottom of the workbench 1, a mounting plate 4 is fixedly connected to the outer wall of the bottom of the workbench 1, a motor 5 is fixedly connected to the outer wall of the mounting plate 4, an output end of the motor 5 is fixedly connected to a rotating shaft 6, and the other end of the rotating shaft 6 is fixedly connected to a cam 7, an outer frame 8 is slidably connected to the inside of the shell 3, a connecting block 10 is fixedly connected to one side of the outer frame 8, a slide groove 9 is provided on one side of the shell 3, the connecting block 10 is slidably connected in the slide groove 9, and the connecting block 10 corresponds to the cam 7, a screen 13 is slidably connected to the bottom of the outer frame 8, a fixing plate 11 is fixedly connected to both side walls of the shell 3, a spring 12 is fixedly connected between the fixing plate 11 and the outer frame 8, a feeding port 26 is provided at the top of the shell 3, the discharge port 2 corresponds to the feeding port 26, and the inner diameter of the feeding port 26 is larger than the inner diameter of the discharge port 2, and a discharge pipe 27 is provided at the bottom of the polishing box 14.

[0026] By opening the valve on the discharge pipe 27, the abrasive fluid will be discharged through the discharge pipe 27 and then flow into the outer frame 8 through the discharge port 2 and the feed port 26. At this time, the motor 5 on the mounting plate 4 is started. After the motor 5 starts working, it will drive the cam 7 on the rotating shaft 6 to rotate. During the rotation process, the cam 7 will repeatedly push the connecting block 10 to move left and right in the chute 9. When the connecting block 10 moves, it will drive the outer frame 8 to move together. During this process, the elastic force of the spring 12 on the fixed plate 11 can make the shaking frequency of the outer frame 8 more appropriate. The screen 13 inside the outer frame 8 can filter and discharge impurities after polishing. This achieves the screening and removal of impurities of the abrasive fluid, allowing the abrasive fluid to be recycled, greatly saving resources. At the same time, it also improves work efficiency. In addition, by turning on the water pump on the water tank 24, water can be allowed to flow through the water pipe 25 to clean the polishing box 14, ensuring the cleanliness of the equipment and preparing for the next polishing work.

[0027] Embodiment 2: The difference between this embodiment and embodiment 1 is that a polishing box 14 is provided on the top of the workbench 1, and a motor 3 20 is fixedly connected to the top of the polishing box 14, and a rotating column 21 is fixedly connected to the output end of the motor 3 20, and a pair of connecting rods 22 are fixedly connected above the rotating column 21, and the bottom of the other end of each connecting rod 22 is fixedly connected to a crankshaft body 23, and the crankshaft body 23 is rotatably connected in the polishing box 14, and a motor 2 15 is fixedly connected to the bottom of the workbench 1, and a rotating rod 16 is fixedly connected to the output end of the motor 2 15, and a cam 2 17 is fixedly connected to the other end of the rotating rod 16, and a connecting plate 2 18 is fixedly connected to the bottom of the polishing box 14, and the cam 2 17 corresponds to the connecting plate 2 18, and two pairs of springs 2 19 are fixedly connected between the bottom of the polishing box 14 and the top of the workbench 1, and a water tank 24 is provided on the top of the workbench 1, and a water pipe 25 is provided outside the water tank 24, and the other end of the water pipe 25 corresponds to the polishing box 14.

[0028] Add the abrasive fluid and polishing solvent into the polishing box 14 respectively. Then, start the motor 3 20 on the top of the polishing box 14. After the motor 3 20 starts running, it will drive the rotating column 21 to rotate. While the rotating column 21 rotates, it will drive the crankshaft body 23 at both ends of the connecting rod 22 to rotate. The rotation of the crankshaft body 23 can fully mix the abrasive fluid and the polishing solvent. At this time, start the motor 2 15 at the bottom of the workbench 1. Under the action of the motor 2 15, the rotating rod 16 is driven to rotate, and when the rotating rod 16 rotates, it drives the cam 2 17 to rotate. The rotation of the cam 2 17 then pushes the connecting plate 2 18 to shake left and right. The shaking of the connecting plate 2 18 will drive the polishing box 14 to shake as a whole, and in this process, the spring 2 19 will continuously stretch and reset, thereby achieving a vibration effect on the polishing box 14. Then, add the small workpiece into the polishing box 14 for polishing. The coordination between these components greatly improves work efficiency. In addition, by turning on the water pump on the water tank 24, water will clean the polishing box 14 through the water pipe 25, completing the post-polishing cleaning work conveniently and quickly.

[0029] Working principle: when the staff needs to polish a small workpiece, first add the abrasive fluid and the polishing solvent into the polishing box 14 respectively, start the motor three 20 on the top of the polishing box 14, and drive the rotating column 21 to rotate under the action of the motor three 20, and the rotating column 21 drives the crankshaft body 23 at both ends of the connecting rod 22 to rotate, so as to fully mix the abrasive fluid and the polishing solvent. At this time, start the motor two 15 at the bottom of the workbench 1, and drive the rotating rod 16 to rotate under the action of the motor two 15. When the rotating rod 16 rotates, it will drive the cam two 17 to rotate, thereby pushing the connecting plate two 18 to shake left and right. The shaking of the connecting plate two 18 drives the polishing box 14 to shake as a whole, and will cause the spring two 19 to continuously stretch and reset, thereby achieving the vibration effect of the polishing box 14. At this time, add the small workpiece into the polishing box 14 for polishing, through Through the cooperation between them, the work efficiency is improved. After the polishing is completed, the abrasive fluid is discharged through the discharge pipe 27 by opening the valve on the discharge pipe 27, and flows into the outer frame 8 through the discharge port 2 and the feed port 26. At this time, the motor 5 on the mounting plate 4 is started, and the cam 7 on the rotating shaft 6 is driven to rotate under the action of the motor 5, and the cam 7 repeatedly pushes the connecting block 10 to move left and right in the slide groove 9, and drives the outer frame 8 to move together when the connecting block 10 moves. The elastic force of the spring 12 on the fixed plate 11 makes the shaking frequency of the outer frame 8 better, and the impurities after polishing are filtered and discharged through the screen 13, realizing the screening and removal of the abrasive fluid, so that the abrasive fluid can be recycled, saving resources and improving work efficiency. By turning on the water pump on the water tank 24, water is used to clean the polishing box 14 through the water pipe 25.
