Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the field of steel bar processing technology, and more specifically, to a steel bar surface grinding apparatus. Background Technology
[0002] A steel bar is a rod-shaped metal product made from steel. It typically has high strength, hardness, and toughness and is widely used in machinery manufacturing, construction engineering, automotive industry, hardware tools, and other fields. It can be used as a structural component or further processed into various mechanical parts.
[0003] Currently, when processing the outer surface of steel bars, operators often need a grinding device. However, while existing grinding devices possess the basic functions of clamping and grinding steel bars, they still have some practical application defects. After the operator finishes grinding the steel bar, whether the right end of the steel bar is released first or the left end is left inside the grinding block before release, one end of the steel bar will always lack support and sag due to its own weight. Over time, this end of the steel bar will squeeze the clamping block or grinding module, causing it to deform. This not only affects the normal service life of the equipment but may also reduce the grinding accuracy and product quality. Therefore, improvements are needed to enhance the stability and efficiency of steel bar grinding operations. Utility Model Content
[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a steel bar surface grinding device, which solves the technical problem of lack of support in the related art.
[0005] According to one aspect, at least one embodiment of this disclosure provides a steel bar surface grinding device, including a worktable, a drive motor fixedly mounted on the back of the worktable, a rotating shaft fixedly sleeved at the other end of the output shaft of the drive motor, the other end of the rotating shaft extending into the interior of the worktable and movably connected to the interior of the worktable, a small gear fixedly sleeved at the front of the outer surface of the worktable, the outer surface of the small gear movably connected to the interior of the worktable, a toothed plate meshing with the outer surface of the small gear, the outer surface of the toothed plate movably connected to the interior of the worktable, the top end of the toothed plate passing through the worktable and extending to the outside of the top end of the worktable and fixedly connected to a support block, a guide block fixedly connected to the bottom end of the left side of the toothed plate, the outer surface of the guide block movably connected to the interior of the worktable.
[0006] As a preferred embodiment of this utility model, a connecting frame is movably connected to the rear of the left side of the top of the workbench, a rectangular block is fixedly installed on the top of the inner surface of the connecting frame, and a power motor is fixedly installed in front of the top left side of the connecting frame.
[0007] As a preferred embodiment of this utility model, a rotating shaft is fixedly sleeved on the other end of the output shaft of the power motor, the right end of the rotating shaft extends into the interior of the rectangular block and is movably connected to the interior of the rectangular block, and a medium-sized gear is fixedly sleeved on the right side of the outer surface of the rotating shaft.
[0008] As a preferred embodiment of this utility model, a grinding block is movably connected to the rear of the rectangular block, and a large gear is fixedly sleeved on the outer surface of the grinding block, with the outer surface of the large gear meshing with the outer surface of the medium gear.
[0009] As a preferred embodiment of this utility model, the left and right sides of the outer surface of the grinding block are fixedly fitted with rings located inside the rectangular block, and the outer surface of the rings is movably connected to the interior of the rectangular block.
[0010] As a preferred embodiment of this utility model, a servo motor is fixedly installed on the right side of the back of the workbench, and a round shaft is fixedly sleeved on the other end of the output shaft of the servo motor, and a long rod is fixedly sleeved on the outer surface of the round shaft.
[0011] As a preferred embodiment of this utility model, the other end of the long rod is hinged to a movable rod, and the other end of the movable rod is hinged to the bottom end of the back of the connecting frame.
[0012] As a preferred embodiment of this utility model, a linear motor is fixedly installed on the right side of the front of the workbench, and a bidirectional threaded screw located inside the workbench is fixedly sleeved at the other end of the output shaft of the linear motor. The outer surface of the bidirectional threaded screw is movably connected to the interior of the workbench.
[0013] As a preferred technical solution of this utility model, the outer surface of the bidirectional threaded screw is threaded with clamping blocks in both the front and rear directions. The top of the clamping blocks passes through the worktable and extends to the outside of the top of the worktable. The outer surface of the bidirectional threaded screw is movably connected to the inside of the worktable.
[0014] As a preferred technical solution of this utility model, the top left rear of the workbench is internally connected to a movable block located at the bottom of the connecting frame. The top of the movable block is fixedly connected to the bottom of the connecting frame, and table legs are fixedly installed at the four corners of the bottom of the workbench.
[0015] The beneficial effects of the embodiments disclosed herein are as follows: 1. In this disclosure, by setting up a drive motor, a rotating shaft, a small gear, a toothed plate, and a support block, when the operator starts the drive motor, the rotating shaft and the small gear will rotate, thereby causing the outer surface of the small gear to mesh with the outer surface of the toothed plate. This will cause the toothed plate to drive the support block to move upward, so that the top of the outer surface of the support block will fit against the outer surface of the steel rod. This ensures that when the operator releases the steel rod from its fixation and removes it, both ends of the steel rod can remain stable, preventing the steel rod from tilting and falling due to unilateral suspension.
[0016] 2. In this disclosure, by setting up a servo motor, a round shaft, a long rod, and a movable rod, when the operator starts the servo motor, the round shaft will drive the long rod to rotate together. Due to the rotation of the long rod, the movable rod will pull the connecting frame to move to the right, thereby enabling the grinding block to perform comprehensive and rapid grinding operations on the outer surface of the steel bar. This operation not only ensures the continuity and uniformity of the grinding trajectory, but also effectively reduces the differences in texture and processing errors on the surface of the steel bar, thus bringing convenience to the operator in actual use.

[0020] 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.
[0021] 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."
[0022] 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. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.
[0023] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0024] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to 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 disclosure.
[0025] 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.
[0026] like Figures 1-6 As shown, a steel bar surface grinding device according to an embodiment of the present disclosure is illustrated, including a worktable 1. A drive motor 2 is fixedly mounted on the back of the worktable 1. A rotating shaft 3 is fixedly sleeved at the other end of the output shaft of the drive motor 2. The other end of the rotating shaft 3 extends into the interior of the worktable 1 and is movably connected to the interior of the worktable 1. A small gear 4 is fixedly sleeved at the front of the outer surface of the worktable 1. The outer surface of the small gear 4 is movably connected to the interior of the worktable 1. A toothed plate 5 is meshed with the outer surface of the small gear 4. The outer surface of the toothed plate 5 is movably connected to the interior of the worktable 1. The top end of the toothed plate 5 passes through the worktable 1 and extends to the outside of the top end of the worktable 1 and is fixedly connected to a support block 6. A guide block 7 is fixedly connected to the bottom left side of the toothed plate 5. The outer surface of the guide block 7 is movably connected to the interior of the worktable 1.
[0027] Since the outer surface of the small gear 4 is connected to the outer surface of the toothed plate 5 by meshing, when the small gear 4 rotates, the toothed plate 5 will move. Due to the design of the guide block 7, the movement of the toothed plate 5 can be well limited.
[0028] In some examples, a connecting frame 8 is movably connected to the rear of the left side of the top of the workbench 1, a rectangular block 9 is fixedly installed on the top of the inner surface of the connecting frame 8, and a power motor 10 is fixedly installed in front of the top left side of the connecting frame 8.
[0029] Because the power motor 10 has a self-locking function, it can maintain stability even when it loses power.
[0030] In some examples, the other end of the output shaft of the power motor 10 is fixedly sleeved with a rotating shaft 11, the right end of the rotating shaft 11 extends into the interior of the rectangular block 9 and is movably connected to the interior of the rectangular block 9, and a medium-sized gear 12 is fixedly sleeved on the right side of the outer surface of the rotating shaft 11.
[0031] Since the outer surface of the rotating shaft 11 and the interior of the rectangular block 9 are both smooth, the friction between the outer surface of the rotating shaft 11 and the interior of the rectangular block 9 can be reduced when the rotating shaft 11 rotates.
[0032] In some examples, a grinding block 13 is movably connected to the rear of the rectangular block 9, and a large gear 14 is fixedly sleeved on the outer surface of the grinding block 13. The outer surface of the large gear 14 meshes with the outer surface of the medium gear 12.
[0033] Because the connection between the large gear 14 and the medium gear 12 is a meshing connection, when the medium gear 12 rotates, the large gear 14 will also rotate along with it.
[0034] In some examples, the left and right sides of the outer surface of the grinding block 13 are fixedly fitted with rings 15 located inside the rectangular block 9, and the outer surface of the rings 15 is movably connected to the interior of the rectangular block 9.
[0035] The design of the two rings 15 can limit the rotation of the polishing block 13.
[0036] In some examples, a servo motor 16 is fixedly installed on the right side of the back of the workbench 1, and a round shaft 17 is fixedly sleeved on the other end of the output shaft of the servo motor 16. A long rod 18 is fixedly sleeved on the outer surface of the round shaft 17.
[0037] Since the connection between the round shaft 17 and the long rod 18 is fixed, when the round shaft 17 rotates, it will cause the long rod 18 to rotate as well.
[0038] In some examples, the other end of the long rod 18 is hinged to a movable rod 19, the other end of which is hinged to the bottom end of the back of the connecting frame 8.
[0039] Because the long rod 18, the movable rod 19 and the connecting frame 8 are all hinged, when the long rod 18 rotates, the movable rod 19 will pull the connecting frame 8 to move as a whole.
[0040] In some examples, a linear motor 20 is fixedly installed on the right side of the front of the worktable 1, and a bidirectional threaded screw 21 located inside the worktable 1 is fixedly sleeved at the other end of the output shaft of the linear motor 20. The outer surface of the bidirectional threaded screw 21 is movably connected to the inside of the worktable 1.
[0041] Since both the outer surface of the bidirectional threaded screw 21 and the outer surface of the worktable 1 are smooth, the movement of the bidirectional threaded screw 21 inside the worktable 1 is smoother.
[0042] In some examples, the bidirectional threaded screw 21 has a clamping block 22 threaded in both the front and rear directions on its outer surface. The top of the clamping block 22 passes through the worktable 1 and extends to the outside of the top of the worktable 1. The outer surface of the bidirectional threaded screw 21 is movably connected to the inside of the worktable 1.
[0043] The design of the two clamping blocks 22 enables the steel bar to be clamped and fixed.
[0044] In some examples, the top left rear of the workbench 1 is internally connected to a movable block 23 located at the bottom of the connecting frame 8. The top of the movable block 23 is fixedly connected to the bottom of the connecting frame 8. Table legs 24 are fixedly installed at the four corners of the bottom of the workbench 1.
[0045] The design of the four table legs 24 provides excellent support for the entire workbench 1.
[0046] Working principle and usage process of this utility model: First, the operator starts the power motor 10 and the servo motor 16. The operation of the power motor 10 causes the rotating shaft 11 and the medium gear 12 to rotate, thereby causing the outer surface of the medium gear 12 to mesh with the outer surface of the large gear 14. This causes the large gear 14 to drive the grinding block 13 to rotate as a whole, allowing the inner surface of the grinding block 13 to grind the outer surface of the steel rod. Meanwhile, the operation of the servo motor 16 causes the round shaft 17 and the long rod 18 to rotate, causing the movable rod 19 to drive the connecting frame 8 to move to the right. This process allows the inner surface of the grinding block 13 to perform a comprehensive grinding operation on the outer surface of the steel rod.
[0047] Finally, after grinding is completed, the operator runs the drive motor 2 and the linear motor 20. The operation of the drive motor 2 causes the rotating shaft 3 and the small gear 4 to rotate, thereby causing the outer surface of the small gear 4 to mesh with the outer surface of the toothed plate 5. This causes the toothed plate 5 to drive the support block 6 to move upward, so that the top of the outer surface of the support block 6 fits against the outer surface of the steel bar, thus providing auxiliary support for the steel bar. Meanwhile, the operation of the linear motor 20 causes the bidirectional threaded screw 21 to rotate, thereby causing the two clamping blocks 22 to move in opposite directions, thus releasing the fixing effect on the steel bar. The operator can then remove the steel bar.
[0048] 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.
