Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of grinding wheel technology, and more specifically, to a grinding wheel for post-processing of metal castings. Background Technology

[0002] Grinding wheels are mechanical equipment used for metal processing and surface treatment. They are widely used in fields such as metal casting. During the metal casting process, burrs and flash often form on the surface of the casting due to the parting surface, gate, and riser of the mold. These burrs and flash not only affect the appearance quality of the product, but may also pose a threat to the safety of the operators.

[0003] Therefore, after the metal castings are produced, they are polished using a grinding wheel machine. When the grinding wheel machine is working, the motor drives the grinding wheel on the grinding wheel machine to rotate, so that it runs at a high speed. After the grinding wheel comes into contact with the surface of the metal casting, the abrasive grains on the surface of the grinding wheel will scrape and grind the surface of the casting to remove excess material from the surface of the casting.

[0004] During grinding, the grinding wheel is mounted on the workbench. The worker usually holds some relatively regular metal castings and moves them to the side of the grinding wheel for grinding. If the metal castings are small in mass and volume, it is easier to grind them. However, some metal castings are small in volume but heavy in mass, so it is more difficult to move the castings left and right for grinding. Utility Model Content

[0005] To overcome the above-mentioned defects, embodiments of this disclosure provide a grinding wheel machine for post-processing of metal castings, which solves the technical problem in the prior art that it is laborious for workers to grind heavy castings by hand.

[0006] According to one aspect, at least one embodiment of this disclosure provides a grinding wheel machine for post-processing of metal castings, including a grinding wheel machine body, a support table, a workpiece disc, a rotating assembly, and a clamping assembly. The support table is fixedly installed on the side of the grinding wheel machine body. The workpiece disc is disposed on the support table via an adjustment assembly. The rotating assembly is disposed on the adjustment assembly. The rotating assembly is used to drive the metal casting on the workpiece disc to rotate, thereby changing the grinding position. The adjustment assembly is provided with two clamping assemblies, which are used to clamp the metal casting on the workpiece disc.

[0007] Furthermore, the adjustment assembly includes a first electric cylinder, a lifting plate, and a translation assembly. There are two first electric cylinders, both of which are installed at the bottom of the support platform. The lifting plate is fixedly connected to the output ends of the two first electric cylinders, and the translation assembly is disposed on the lifting plate.

[0008] Furthermore, the translation component includes a screw, a first motor, and a moving block. The screw is rotatably mounted on the lifting plate, the first motor is mounted on the side of the lifting plate, and the output end of the first motor is coaxially connected to the screw. The moving block is mounted on the screw.

[0009] Furthermore, the rotating assembly includes a rotating shaft, a second motor, transmission wheels, and a transmission belt. The workpiece disc is rotatably mounted on the top of the moving block via the rotating shaft. The second motor is mounted on the side of the moving block. Transmission wheels are fixedly mounted on the output ends of both the rotating shaft and the second motor. The transmission belt is tensioned and sleeved on the two transmission wheels.

[0010] Furthermore, the clamping assembly includes a support plate, a second electric cylinder, and a clamping block. The support plate is fixedly installed on the side of the movable block, the second electric cylinder is installed on the side of the support plate, and the clamping block is fixedly connected to the output end of the second electric cylinder.

[0011] To ensure that the movable block can move horizontally on the screw, a groove is further provided at the inner top of the lifting plate, and the movable block is slidably installed in the groove of the lifting plate by a limiting rod.

[0012] To prevent the drive wheel and drive belt from being touched by impurities during grinding, a protective cover is detachably installed on the top of the moving block. The drive wheel and drive belt are both located inside the protective cover, and the rotating shaft is rotatably mounted on the protective cover.

[0013] In order to enable the clamping block to clamp the metal casting on the workpiece disk, the bottom end of the clamping block is at the same horizontal position as the top end of the workpiece disk.

[0014] The beneficial effects of the embodiments disclosed herein are as follows:

[0015] 1. In this disclosure, when grinding a metal casting, the metal casting can be placed on a workpiece plate, and the metal casting on the workpiece plate can be clamped and fixed by a clamping assembly. The position and height of the metal casting can be moved by an adjusting assembly, so that the side of the metal casting can be ground by the grinding wheel body.

[0016] 2. In this disclosure, if it is necessary to grind other surfaces of the metal casting, the workpiece disk and the metal casting can be rotated by the rotating component, thereby changing the angle of the metal casting, and then pushing it to the side of the grinding wheel of the grinding wheel body for grinding;

[0017] In summary, this grinding machine, through the cooperation between the support platform, workpiece disc, rotating assembly, and clamping assembly, can place metal castings on the workpiece disc without manual handling, and then grind the metal castings through the grinding machine body. This is much less labor-intensive than having workers hold the metal castings and grind them against the grinding wheel. Attached Figure Description

[0024] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0025] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0026] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components.

[0029] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] like Figures 1-4 As shown, a grinding wheel for post-processing of metal castings according to an embodiment of the present disclosure is illustrated. The grinding wheel includes a grinding wheel body 1, a support platform 2, a workpiece disk 3, a rotating assembly, and a clamping assembly. The support platform 2 is fixedly installed on the side of the grinding wheel body 1. The workpiece disk 3 is set on the support platform 2 through an adjustment assembly. The rotating assembly is set on the adjustment assembly. The rotating assembly is used to drive the metal casting on the workpiece disk 3 to rotate, thereby changing the grinding position. Two clamping assemblies are provided on the adjustment assembly. The clamping assemblies are used to clamp the metal casting on the workpiece disk 3.

[0031] like Figure 4 and Figure 3As shown, when grinding a metal casting, the metal casting is first placed on the workpiece disk 3, and then the side of the metal casting is made to fit against the grinding wheel on the grinding wheel body 1. The metal casting is then clamped and fixed by a clamping assembly, which includes a support plate 13, a second electric cylinder 14, and a clamping block 15. The support plate 13 is fixedly installed on the side of the moving block 8, and the second electric cylinder 14 is installed on the side of the support plate 13. The clamping block 15 is fixedly connected to the output end of the second electric cylinder 14. Specifically, by activating the second electric cylinder 14, the output end of the second electric cylinder 14 drives the clamping block 15 to move, thereby clamping both sides of the metal casting. Because the bottom end of the clamping block 15 is at the same horizontal position as the top end of the workpiece disk 3, it can be ensured that the metal casting on the workpiece disk 3 can be clamped when the clamping block 15 moves, and it will not be blocked by the workpiece disk 3.

[0032] like Figure 2 As shown, after clamping, the grinding machine body 1 is started, and the grinding wheel is rotated to grind the side of the metal casting. During grinding, the position of the metal casting can be moved by adjusting the components, so that different positions of the metal casting can be ground. The adjusting components include a first electric cylinder 4, a lifting plate 5, and a translation component. There are two first electric cylinders 4, both of which are installed at the bottom of the support platform 2. The lifting plate 5 is fixedly connected to the output ends of the two first electric cylinders 4. The translation component is set on the lifting plate 5 and includes a screw 6, a first motor 7, and a moving block 8. The screw 6 is rotatably installed on the lifting plate 5. The first motor 7 is installed on the side of the lifting plate 5, and the output end of the first motor 7 is coaxially connected to the screw 6. The moving block 8 is installed on the screw 6.

[0033] Specifically, by starting the first motor 7, the output end of the first motor 7 drives the screw 6 to rotate on the lifting plate 5. It should be noted that the moving block 8 and the screw 6 are driven by a rolling thread, so the moving block 8 can move horizontally on the screw 6. Furthermore, a sliding groove is provided at the inner top of the lifting plate 5, and the moving block 8 is movably installed in the sliding groove of the lifting plate 5 by a limiting rod 16. By limiting the moving block 8 by the limiting rod 16, the moving block 8 can move horizontally on the screw 6, thereby driving the workpiece disk 3 and the metal casting on the workpiece disk 3 to move horizontally, thereby polishing the side of the metal casting.

[0034] like Figure 3As shown, after one side of the metal casting has been ground, if the other side needs to be ground, the metal casting can be rotated by a rotating assembly. The rotating assembly includes a rotating shaft 9, a second motor 10, transmission wheels 11, and a transmission belt 12. The workpiece disc 3 is rotatably mounted on the top of the moving block 8 via the rotating shaft. The second motor 10 is mounted on the side of the moving block 8. Transmission wheels 11 are fixedly mounted on the output ends of both the rotating shaft 9 and the second motor 10. Transmission belts 12 are tensioned and fitted onto the two transmission wheels 11. Specifically, by starting the second motor 10, the output end of the second motor 10 drives the transmission wheels 11 to rotate. Under the tensioning action of the transmission belt 12, the transmission wheel 11 on the rotating shaft 9 is driven to rotate, which in turn drives the rotating shaft 9 to rotate. The rotating shaft 9 then drives the workpiece disk 3 to rotate, and the workpiece disk 3 drives the metal casting to rotate. After the rotation is completed, the metal casting is pushed on the workpiece disk 3, and the side of the metal casting is pushed to fit against the side of the grinding wheel. The top of the moving block 8 is detachably equipped with a protective cover 17. The transmission wheel 11 and the transmission belt 12 are both located inside the protective cover 17, and the rotating shaft 9 is rotatably mounted on the protective cover 17. When grinding the metal casting, the contact between the transmission wheel 11 and the transmission belt 12 can be protected.

[0035] Working principle: When grinding metal castings, the metal casting is placed on the workpiece disc 3, and the side of the metal casting is made to fit against the grinding wheel on the grinding machine body 1. It should be noted that when the metal casting is placed on the workpiece disc 3, the side of the metal casting to be ground is on the outside of the workpiece disc 3, so as to ensure that the grinding wheel does not touch the side of the workpiece disc 3 during grinding. Then, the second electric cylinder 14 is started, and the output end of the second electric cylinder 14 drives the clamping block 15 to move, thereby clamping both sides of the metal casting. After clamping, the grinding machine body 1 is started, and the grinding wheel is rotated to grind the side of the metal casting. During grinding, the first motor 7 is started, and the output end of the first motor 7 drives the screw 6 to rotate on the lifting plate 5. The moving block 8 moves horizontally on the screw 6, thereby driving the workpiece disc 3 and the metal casting on the workpiece disc 3 to move horizontally, thereby grinding the side of the metal casting.

[0036] If grinding is required on the other side, start the second motor 10. The output of the second motor 10 drives the transmission wheel 11 to rotate. Under the tension of the transmission belt 12, the transmission wheel 11 on the rotating shaft 9 rotates, which in turn drives the rotating shaft 9 to rotate. The rotating shaft 9 then drives the workpiece disk 3 to rotate. The workpiece disk 3 drives the metal casting to rotate. After the rotation is complete, push the metal casting on the workpiece disk 3 to push the side of the metal casting to fit against the side of the grinding wheel, and then grind it again.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
