Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a device for grinding castings. Background Technology

[0002] Castings are products manufactured through a casting process. After casting, the resulting castings typically require post-processing, primarily to remove burrs and residual parts from the pouring head, resulting in a smoother surface that meets design requirements. However, under current technological conditions, operators typically handle castings directly by hand during grinding. Due to the small size and compact shape of these castings, the operator's hand inevitably comes into contact with the high-speed rotating grinding wheel during grinding, increasing the risk of accidental hand contact and potentially leading to serious accidents. Therefore, designing a device for grinding castings to address these issues is particularly necessary. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a device for grinding castings.

[0004] To achieve the above objectives, the technical solution of this utility model is: a device for grinding castings, comprising a mounting beam fixed on the body of a grinding machine, characterized in that a mounting seat is fixed on the mounting beam, the mounting seat is rotatably connected to one end of a universal ball joint via a connecting turntable, the other end of the universal ball joint is fixedly connected to one end of a movable rod, the other end of the movable rod is fixedly connected to a handle sleeve, a positioning cylinder is sleeved in the middle of the movable rod, a locking element is threaded onto the positioning cylinder, an L-shaped limiting element is fixed on the positioning cylinder, and an operating handle is also fixed on the positioning cylinder.

[0005] The grinding machine body is also fixed with a base plate, and a feeding guide with an inclined panel is fixed on the base plate.

[0006] The sloping panel is made of perforated board.

[0007] The base plate is also provided with a groove, in which a collection box is placed, and the feeding guide has a strip that matches the collection box.

[0008] The positioning cylinder also has an inlet section.

[0009] The movable rod also has a recessed portion in the middle that cooperates with the locking element.

[0010] The locking component is a hand-tightening component.

[0011] By adopting the above technical solution, the beneficial effects of this utility model are: In this invention, the left hand holds the glove, while the right hand inserts one end of the casting between the positioning cylinder and the limiting component. The left hand then gradually moves the positioning cylinder closer to the grinding wheel of the grinding machine body. At the same time, the free left hand holds the operating handle and slightly rotates it up and down to ensure that the remaining part of the pouring head in the middle of the casting fully contacts the grinding wheel, thereby completing the grinding of the casting. This eliminates the need for the operator to directly hold the casting for grinding, greatly improving the safety of the operation. Attached Figure Description

Detailed Implementation

[0013] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0014] like Figure 1-4 As shown, the device for grinding castings includes a mounting beam 5 fixed on the grinding machine body 15. In this embodiment, the grinding machine body 15 has a rotatable grinding wheel 15a, which is rotated electrically. A mounting base 4 is fixed on the mounting beam 5. The mounting base 4 is rotatably connected to one end of a connecting turntable 13 and a universal ball joint 14. The other end of the universal ball joint 14 is fixedly connected to one end of a movable rod 6, and the other end of the movable rod 6 is fixedly connected to a handle 8. With this structure, the movable rod 6 can rotate and can also move closer to or away from the grinding wheel 15a. A positioning cylinder 9a is sleeved in the middle of the movable rod 6. A locking element 11 is threadedly connected to the positioning cylinder 9a. Specifically, the locking element 11 is a hand-tightening element. An L-shaped limiting element 12 is fixed on the positioning cylinder 9a, and an operating handle 10 is also fixed on the positioning cylinder 9a.

[0015] The grinding machine body 15 is also fixed with a base plate 1, and a feeding guide table 3 with a slanted panel is fixed on the base plate 1; specifically, the slanted panel is a perforated plate.

[0016] The base plate 1 is also provided with a groove 1a, in which a collection box 2 is placed, and the unloading guide 3 has a strip 7 that matches the collection box 2.

[0017] The positioning cylinder 9a also has an inlet 9, which facilitates the placement of the casting 16 between the positioning cylinder 9a and the limiting member 12.

[0018] The movable rod 6 also has a recessed portion 6a in the middle that cooperates with the locking member 11. With this structure, the locking member 11 can have sufficient contact area with the movable rod 6.

[0019] In this invention, the left hand holds the handle glove 8, while the right hand inserts one end of the casting 16 between the positioning cylinder 9a and the limiting member 12. The left hand then gradually moves the positioning cylinder 9a closer to the grinding wheel 15a on the grinding machine body 15. At this point, the casting 16 is positioned between the positioning cylinder 9a, the limiting member 12, and the grinding wheel 15a, thus preventing it from falling off the positioning cylinder 9a. Simultaneously, the free left hand holds the operating handle 10 and slightly rotates it up and down to ensure that the remaining part of the pouring head in the middle of the casting 16 fully contacts the grinding wheel 15a, thereby completing the grinding of the casting 16. After grinding, the left hand moves the movable rod 6 outward away from the grinding wheel 15a, removing the casting 16 from the positioning cylinder 9a and the limiting member 12. The casting 16 is then collected into the collection box 2 along the unloading guide 3. This eliminates the need for the operator to directly hold the casting 16 for grinding, greatly improving operational safety.

[0020] In this embodiment, casting 16 refers to the handle casting, which is as follows before and after polishing: Figure 5 As shown.

[0021] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0022] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
