Description

Technical Field

[0001] This invention relates to the field of polishing technology for cast steel parts, and specifically to a polishing device for wear-resistant cast steel parts. Background Technology

[0002] After casting, cast steel parts have a relatively rough surface with burrs, requiring polishing to ensure their quality. When polishing cast steel parts using a magnetic polishing machine, the magnetic needles, polishing fluid, and workpiece are placed together in a container. The container is then placed on the worktable of the magnetic polishing machine, and the machine is started; the magnetic needles then polish the workpiece.

[0003] When polishing workpieces with holes, magnetic needles may enter the holes. After removing the workpiece, workers need to manually remove the magnetic needles from the holes, which is a cumbersome operation and requires a high level of physical exertion. Therefore, we propose a polishing device for wear-resistant cast steel parts. Summary of the Invention

[0004] (i) In view of the shortcomings of the prior art, the present invention provides a polishing device for wear-resistant cast steel parts, which overcomes the problem that the existing polishing devices require manual removal of the magnetic needles inside the workpiece, simplifies the operation and reduces the workload of the workers.

[0005] (II) To achieve the above objectives, the present invention is implemented through the following technical solution: a polishing device for wear-resistant cast steel parts, including a magnetic machine, a surrounding strip installed on the magnetic machine, an immersion shell installed inside the surrounding strip, a bracket fixed on the magnetic machine, a loading mechanism for placing wear-resistant cast steel parts on the bracket, and a power mechanism for driving the loading mechanism installed on the magnetic machine.

[0006] The loading mechanism includes a hydraulic rod mounted on a bracket. A movable plate is fixed to the movable end of the hydraulic rod. Two sets of connecting plates are movably mounted on the movable plate. An elastic telescopic rod is fixed to the connecting plate. A bearing frame is fixed to the other end of the elastic telescopic rod. A loading shell with coarse holes can be detachably installed inside the bearing frame.

[0007] The power mechanism includes a support plate fixed on the magnetic motor, a motor mounted on the support plate, a rotating disk fixed at the output end of the motor, an eccentric rod fixed on the rotating disk, a swing arm rotatably mounted on the eccentric rod, a slide bar rotatably mounted at the other end of the swing arm, and a slide rail frame fixed to the bearing frame slidably mounted on the slide bar.

[0008] Preferably, the movable plate is provided with symmetrical grooves, a slider is slidably installed in the groove, a limiting post fixed to the groove is slidably installed on the slider, a spring is sleeved on the limiting post, the spring is fixed between the slider and the groove, and the connecting plate is fixed to the corresponding slider.

[0009] Preferably, two sets of oscillation mechanisms are provided between the bracket and the bearing frame. The oscillation mechanism includes a vertical rod fixed on the bracket, and an uneven guide rail plate fixed to the other end of the vertical rod. The bearing frame is equipped with guide wheels that cooperate with the guide rail plate.

[0010] Preferably, the two sets of the turbulence mechanism are located on both sides of the moving plate.

[0011] Preferably, the support frame is provided with two sets of anti-detachment mechanisms. The anti-detachment mechanism includes a pull rod that is slidably installed on the support frame. One end of the pull rod is fixed with a circular plate, and a second spring is sleeved on the pull rod. The second spring is fixed between the circular plate and the support frame. A card plate is rotatably installed on the end of the pull rod away from the circular plate. The loading shell is provided with a slot that cooperates with the card plate.

[0012] Preferably, a filter frame is installed inside the immersion shell, and handles are symmetrically fixed on the filter frame.

[0013] Preferably, the size of the coarse holes on the loading shell is larger than the size of the filter holes on the filter frame.

[0014] Preferably, the top and bottom of the slide frame are not closed, and the cross-section of the slide bar is trapezoidal.

[0015] (III) This invention provides a polishing device for wear-resistant cast steel parts, which has the following beneficial effects:

[0016] 1. By adding an immersion shell, a loading mechanism, and a power mechanism, the workpiece is placed in the loading mechanism. The loading mechanism is controlled to move downwards into the liquid, magnetic needles are poured in, and the magnetic polishing machine is started. After polishing, the loading mechanism is controlled to move upwards to its original position, and the power mechanism is controlled to drive the workpiece in the loading mechanism to flip. The magnetic needles in the workpiece channel will be shaken off, eliminating the need for manual removal of the magnetic needles remaining in the workpiece. This simplifies the operation and reduces the workload of the workers.

[0017] 2. By adding a tumbling mechanism, the workpiece and magnetic needle are also tumbling up and down during the horizontal flipping process, which improves the effect of the magnetic needle falling out of the workpiece and facilitates the rapid falling out of the magnetic needle.

[0018] 3. By adding an anti-detachment mechanism, the card plate can be pulled outward to disengage from the slot, and the loading shell can be removed. Then, the staff can pour the polished workpiece out of the loading shell. The operation is simple, quick and easy to use.

[0019] 4. By adding a filter frame, the magnetic needles that fall out of the coarse holes in the loading shell fall into the filter frame. When the filter frame is removed from the immersion shell, the magnetic needles will be trapped inside the filter frame, which also makes it easier to separate and remove the magnetic needles.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0030] Example 1

[0031] like Figures 1-7As shown, a polishing device for wear-resistant cast steel parts includes a magnetic machine 1, with a retaining strip 5 installed on the magnetic machine 1. An immersion shell 3 is installed inside the retaining strip 5, which prevents the immersion shell 3 from shifting. Water and polishing fluid can be injected into the immersion shell 3. A support 2 is fixed on the magnetic machine 1, and a loading mechanism 4 for placing the wear-resistant cast steel parts is provided on the support 2. A power mechanism 7 for driving the loading mechanism 4 is also installed on the magnetic machine 1. Water and polishing fluid are poured into the immersion shell 3 beforehand. Then, the workpiece is placed in the loading mechanism 4, and the loading mechanism 4 is controlled to move downwards until the workpiece is immersed in the liquid. Then, magnetic needles are poured into the loading mechanism 4, and the magnetic machine is started to polish the workpiece. After polishing, the loading mechanism 4 is controlled to move upwards to its original position, and the power mechanism 4 is controlled to cause the workpiece inside the loading mechanism 4 to flip, causing the magnetic needles in the workpiece's channels to fall off. This eliminates the need for manual removal of residual magnetic needles from the workpiece, simplifying the operation and reducing the workload of the workers.

[0032] The loading mechanism 4 includes a hydraulic rod 41 mounted on the bracket 2. A movable plate 42 is fixed to the movable end of the hydraulic rod 41. Two sets of connecting plates 46 are movably mounted on the movable plate 42. An elastic telescopic rod 43 is fixed on the connecting plate 46. A bearing frame 44 is fixed to the other end of the elastic telescopic rod 43. A loading shell 45 with a coarse hole is detachably installed inside the bearing frame 44. The diameter of the coarse hole is larger than the outer diameter of the magnetic needle. The loading shell 45 is detachable, allowing all workpieces to be poured out at once. Activating the hydraulic rod 41 moves the moving plate 42, connecting plate 46, and elastic telescopic rod 43 downwards, which in turn moves the bearing frame 44 downwards, thus moving the loading shell 45 downwards until it extends into the immersion shell 3. The liquid in the immersion shell 3 enters the loading shell 45 through the gap between the bearing frame 44 and the loading shell 45 and through the coarse holes. At this point, the magnetic needle and workpiece can be poured into the loading shell 45. Activating the magnetic motor 1 causes the magnetic needle to agitate, achieving polishing of the workpiece. The operation is simple and convenient.

[0033] The power mechanism 7 includes a support plate 71 fixed on the magnetizer 1. A motor 72 is mounted on the support plate 71. A rotating disk 73 is fixed to the output end of the motor 72. An eccentric rod 74 is fixed to the rotating disk 73. A swing rod 75 is rotatably mounted on the eccentric rod 74. A slide bar 77 is rotatably mounted on the other end of the swing rod 75. A slide rail frame 76 fixed to the bearing frame 44 is slidably mounted on the slide bar 77. Specifically, the top and bottom ends of the slide rail frame 76 are not closed, and the cross-section of the slide bar 77 is trapezoidal. After polishing is completed, the loading shell 45 is moved back to its original position, and the motor 72 is started to drive the rotating disk 73 to rotate, which in turn drives the eccentric rod 74 to rotate. Through the transmission of the swing rod 75, the slide bar 77 is driven to move back and forth horizontally, which in turn drives the slide frame 76 and the support frame 44 to move back and forth horizontally. The loading shell 45 on the support frame 44 moves back and forth accordingly, and the workpiece and magnetic needles inside move accordingly. The magnetic needles fall from the coarse hole into the immersion shell 3. At the same time, the magnetic needles in the workpiece channel will also fall out of the channel. There is no need to manually remove the magnetic needles remaining in the workpiece, which simplifies the operation and reduces the workload of the staff.

[0034] Specifically, the movable plate 42 has symmetrically formed grooves 421, and a slider 422 is slidably installed in the groove 421. A limiting post 423, which is fixed to the groove 421, is slidably installed on the slider 422. A spring 424 is sleeved on the limiting post 423 and fixed between the slider 422 and the groove 421. The connecting plate 46 is fixed to the corresponding slider 422. The slider 422 plays a supporting role and can move within the groove 421, ensuring the normal movement of the support frame 44.

[0035] Example 2

[0036] refer to Figure 3 and Figure 5 Similar to Embodiment 1, but with an optimization: two sets of turbulence mechanisms 8 are provided between the support 2 and the bearing frame 44. Each turbulence mechanism 8 includes a vertical rod 81 fixed to the support 2, with an uneven guide rail plate 82 fixed to the other end of the vertical rod 81. A guide wheel 83, which works in conjunction with the guide rail plate 82, is installed on the bearing frame 44. When the loading shell 45 moves back to its original position, the guide wheel 83 contacts the guide rail plate 82. During the reciprocating movement of the loading shell 45, the guide wheel 83 reciprocates. Limited by the guide rail plate 82 and under the elastic force of the elastic telescopic rod 43, the bearing frame 44 and the loading shell 45 inside it turbulently up and down, subsequently causing the workpiece and magnetic needle to turbulent up and down. During the horizontal flipping of the workpiece and magnetic needle, they also turbulently up and down, improving the effect of the magnetic needle falling out of the workpiece and facilitating its rapid exit.

[0037] Specifically, the two sets of agitation mechanisms 8 are located on both sides of the moving plate 42. The arrangement of the two sets of agitation mechanisms 8 is conducive to the smooth agitation of the loading shell 45.

[0038] Example 3

[0039] refer to Figure 4 and Figure 6 Similar to Embodiment 1, but with an improvement, the support frame 44 is provided with two sets of anti-detachment mechanisms 6. The anti-detachment mechanism 6 includes a pull rod 61 slidably mounted on the support frame 44. One end of the pull rod 61 is fixed with a circular plate 62, and a second spring 63 is sleeved on the pull rod 61. The second spring 63 is fixed between the circular plate 62 and the support frame 44. A clamping plate 64 is rotatably mounted on the end of the pull rod 61 away from the circular plate 62. The loading shell 45 is provided with a slot 65 that cooperates with the clamping plate 64. In this process, after the workpiece is polished and all the magnetic needles have fallen out, pull the clamping plate 64 outward to disengage it from the clamping slot 65 and rotate it. Similarly, the other clamping plate 64 can be disengaged from the clamping slot 65. At this point, the loading shell 45 can be removed, and the polished workpiece can then be poured out of the loading shell 45. The operation is simple, quick, and easy to use. In the reverse operation, under the action of the second spring 63, the loading shell 45 can be clamped into the bearing frame 44, making installation and disassembly relatively convenient.

[0040] Example 4

[0041] refer to Figure 1 Similar to Example 1, but with an improvement: a filter frame 9 is installed inside the immersion shell 3, and handles are symmetrically fixed on the filter frame 9. Magnetic needles that fall through the coarse holes in the loading shell 45 land inside the filter frame 9. When the filter frame 9 is removed from the immersion shell 3, the magnetic needles are trapped inside, facilitating their separation and removal.

[0042] Specifically, the size of the coarse holes on the loading shell 45 is larger than the size of the filter holes on the filter frame 9. With this design, the magnetic needle can leak out through the coarse holes but will not pass through the filter holes, thus trapping the magnetic needle inside the filter frame 9.

[0043] All components used in this application are standard parts that can be purchased from the market. The specific connection methods of each part adopt conventional methods such as bolts, rivets and welding that are mature in the existing technology. The machinery, parts and electrical equipment all adopt conventional models in the existing technology.

[0044] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of the present invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of the present invention, they are all within the protection scope of the present invention.
