Description

Technical Field

[0001] This utility model relates to the field of casting processing technology, and in particular to a device for grinding burrs on the surface of castings. Background Technology

[0002] Castings are metal shaped objects obtained by various casting methods. They are objects with a certain shape, size and properties obtained by pouring, injecting, sucking or other casting methods into a pre-prepared mold after smelting liquid metal, cooling and then grinding.

[0003] After casting is completed, some burrs and rough edges are usually produced. Since castings are usually made of metal, the burrs and rough edges need to be removed by grinding. When grinding, it is usually done manually with a hand-held grinding machine. However, when operating manually, it is easy to over-grind the material due to the force, which will affect the quality of the casting. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a device for grinding burrs on the surface of castings, thereby solving the problems mentioned in the background section.

[0005] A device for polishing burrs on the surface of castings includes a worktable and a driving mechanism and a polishing mechanism mounted on the worktable. The driving mechanism includes a gear ring, an annular guide rail one, a bracket, a motor one, a gear, a motor two, a lead screw, and a slide block. The gear ring is mounted in the middle of the worktable. The annular guide rail one is mounted around the lower outer wall of the gear ring. The bracket is slidably arranged along the annular guide rail one. The motor one is mounted at one end of the bracket one. The gear is fixedly mounted at the output end of the motor one and meshes with the gear ring for transmission. The motor two is mounted at the top of the bracket. The lead screw is mounted at the output end of the motor two. The slide block is connected to the lead screw for transmission and slides along the side of the other end of the bracket.

[0006] The grinding mechanism is mounted on the drive mechanism and includes a screw, an adjusting rod, a spring, a connecting plate, a fixed plate, and a grinding machine. The connecting plate is set through the slide block by the screw and the screw can be locked on the slide block by a nut. The grinding machine is mounted on the fixed plate. The fixed plate passes through the connecting plate and the slide block by the adjusting rod. The spring is installed between the fixed plate and the connecting plate and is sleeved on the adjusting rod.

[0007] By adopting the above technical solution, it is convenient to automatically perform surface treatment on castings. The spring buffer contraction prevents the grinding wheel and the material from being too tightly packed, thus avoiding over-grinding of the castings.

[0008] A positioning mechanism for applying pressure and positioning the casting is also installed on one side of the bracket via a mounting plate. The mechanism includes an electric cylinder and a pressure plate. The electric cylinder is mounted on the mounting plate, and the pressure plate is mounted at the output end of the electric cylinder.

[0009] By adopting the above technical solution, the casting is limited.

[0010] A support platform is also installed in the middle of the workbench, and the center point of the support platform corresponds vertically to the center point of the pressure plate.

[0011] By adopting the above technical solution, it is convenient to place the casting in the center.

[0012] The outer periphery of the support platform is also provided with a second annular guide rail installed on the workbench, and the bottom of the other end of the bracket slides along the second annular guide rail.

[0013] By adopting the above technical solution, the support can slide stably.

[0014] The grinding wheel of the grinding machine is positioned so that its side faces the vertical center line of the gear ring.

[0015] The above technical solution facilitates the grinding of castings.

[0016] The beneficial effects of this invention's casting surface burr grinding device are:

[0017] Adjust the grinding machine according to the diameter of the casting so that the grinding wheel of the grinding machine contacts the surface of the casting. Slightly push the connecting plate to compress the spring. Then turn the nut on the screw to lock the screw on the slide. This completes the position adjustment of the grinding machine. The spring's buffer contraction prevents the grinding wheel and the material from being too close, thus preventing over-grinding of the casting. It also allows for convenient automatic surface treatment of the casting. Attached Figure Description

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0022] Reference Figure 1-2 A burr removal device for casting surfaces includes a worktable 1 and a drive mechanism and a grinding mechanism mounted on the worktable 1. The drive mechanism includes a gear ring 2, an annular guide rail 3, a bracket 4, a motor 5, a gear 6, a second motor 7, a lead screw 8, and a slide block 11. The gear ring 2 is mounted in the middle of the worktable 1. The annular guide rail 3 is mounted around the lower outer wall of the gear ring 2. The bracket 4 is slidably mounted along the annular guide rail 3. The motor 5 is mounted at one end of the bracket 4. The gear 6 is fixedly mounted at the output end of the motor 5 and meshes with the gear ring 2 for transmission. The second motor 7 is mounted at the top of the bracket 4. The lead screw 8 is mounted at the output end of the second motor 7. The slide block 11 is connected to the lead screw 8 for transmission and slides along the side of the other end of the bracket 4.

[0023] The grinding mechanism is mounted on the drive mechanism and includes a screw 12, an adjusting rod 13, a spring 14, a connecting plate 15, a fixed plate 16, and a grinding machine 17. The connecting plate 15 is set through the slide block 11 by the screw 12, and the screw 12 can be locked on the slide block 11 by a nut. The grinding machine 17 is mounted on the fixed plate 16. The fixed plate 16 passes through the connecting plate 15 and the slide block 11 by the adjusting rod 13. The spring 14 is installed between the fixed plate 16 and the connecting plate 15 and is sleeved on the adjusting rod 13.

[0024] A positioning mechanism for pressurizing and positioning the casting is also installed on one side of the bracket 4 via a mounting plate. This mechanism includes an electric cylinder 18 and a pressure plate 19. The electric cylinder 18 is mounted on the mounting plate, and the pressure plate 19 is mounted at the output end of the electric cylinder 18. The casting can be centered and placed on the support platform 10. The electric cylinder 18 is driven to apply pressure to the upper end of the casting through the pressure plate 19, thus restricting it to the support platform 10.

[0025] According to the diameter of the casting, adjust the grinding machine 17 so that the grinding wheel of the grinding machine 17 contacts the surface of the casting, and slightly push the connecting plate 15 to compress the spring 14. Then rotate the nut on the screw 12 to lock the screw 12 on the slide 11, thus completing the position adjustment of the grinding machine 17.

[0026] The drive motor 7 drives the slide block 11 to move up and down through the lead screw 8, which can control the grinding machine 17 to grind the casting in the up and down position.

[0027] During this period, the drive motor 5 can drive the gear 6 to rotate. Since the gear 6 and the gear ring 2 are meshed, when the gear 6 moves along the gear ring 2, it can drive the bottom of one end of the bracket 4 to move synchronously along the annular guide rail 3. The bottom of the other end of the bracket 4 can slide along the annular guide rail 9. At this time, the position of the motor 7 can be adjusted to perform up and down grinding on different positions on the side of the casting.

[0028] A support platform 10 is also installed in the middle of the workbench 1. The center point of the support platform 10 corresponds vertically to the center point of the pressure plate 19, so that the casting can be placed in the center of the support platform 10 for subsequent grinding by the grinding machine 17.

[0029] The outer periphery of the support platform 10 is also provided with a second ring guide rail 9 installed on the workbench 1. The bottom of the other end of the bracket 4 slides along the second ring guide rail 9, so that the bracket 4 can maintain a stable state when moving.

[0030] The grinding wheel of the grinding machine 17 is positioned with its side facing the vertical center line of the toothed ring 2, so as to facilitate the movement of the grinding machine 17 to grind the circumference of the casting.

[0031] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
