Description

Technical Field

[0001] This utility model belongs to the technical field of polishing equipment, and in particular relates to a valve nut polishing equipment with mechanical automatic feeding function. Background Technology

[0002] Polishing is a crucial step in the production and processing of valve nuts. Its purpose is to remove defects such as burrs, oxide layers, and scratches from the nut surface, improve the surface smoothness and quality of the nut, and thus enhance the overall sealing performance and service life of the valve.

[0003] In the existing technology, after the nut is polished, it needs to be manually removed and then the nut to be polished is installed. During this process, polishing cannot be performed, resulting in low efficiency.

[0004] To address the aforementioned issues, this utility model document proposes a valve nut polishing device that incorporates an automatic mechanical feeding function. Utility Model Content

[0005] The purpose of this invention is to provide a valve nut polishing device that works in conjunction with an automatic mechanical feeding function, which can improve the automation level of the entire production process, further enhance production efficiency, and solve existing technical problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: A valve nut polishing device with an automatic mechanical feeding function, used for polishing valve nuts, comprising: A base, with a vertical plate fixed to its top, and an adjusting shaft rotating inside the vertical plate. The surface of the adjusting shaft is used to fit a nut, and a set of positioning components is provided inside the adjusting shaft to fix the nut to the surface of the adjusting shaft. The top of the base is provided with a first groove, and the first groove is provided with a set of polishing components for polishing the nut. To facilitate loading and unloading onto the adjusting shaft, a second groove is provided at the top of the base. A return frame slides within the second groove, and a loading frame rotates at the top of the return frame. The top of the loading frame has two receiving slots, which are used to receive the nut to be polished and the nut after polishing, respectively. A set of loading and unloading components is provided between the base and the second groove.

[0007] Optionally, the positioning component includes a fourth groove formed within the adjusting shaft, two arc-shaped clamps sliding within the fourth groove, a fifth groove formed within each of the two arc-shaped clamps, two threaded blocks sliding within the fourth groove, a bidirectional lead screw rotating within the fourth groove, two sliders fitted onto the surface of the bidirectional lead screw that cooperate with the positive and negative helical grooves on the surface of the bidirectional lead screw, two sliders respectively fixed within the two threaded blocks, connecting rods fixed at both ends of the two threaded blocks, four connecting rods respectively sliding within the two fifth grooves, slide rods fixed within each of the four connecting rods, two slide grooves formed within each of the two fifth grooves, four slide rods respectively sliding within the four slide grooves, and a third motor fixed to the side end of the adjusting shaft, the third motor being fixedly connected to the bidirectional lead screw via a coupling; Specifically, by activating the third motor, a bidirectional lead screw is driven to rotate. The bidirectional lead screw causes two threaded blocks to move in opposite directions, which in turn causes four sliding rods to move in opposite directions, thereby driving two arc-shaped clamping plates to move in opposite directions. Optionally, a third groove is provided in the vertical plate, a worm gear rotates in the third groove, a worm wheel that meshes with the worm gear is fixed on the surface of the adjusting shaft, and a second motor is fixed to the side end of the vertical plate. The second motor is fixedly connected to the worm gear through a coupling. The process involves starting a second motor to drive a worm gear, which in turn drives a worm wheel to rotate. The worm wheel can then adjust the angle of the adjusting shaft, facilitating polishing.

[0008] Optionally, both of the curved surfaces of the curved clamps are provided with anti-slip pads.

[0009] Optionally, the polishing assembly includes a U-shaped frame that slides within a first groove, a polishing roller that rotates within the U-shaped frame, a fourth motor fixed to the side end of the U-shaped frame, the fourth motor being fixedly connected to the polishing roller via a coupling, a first lead screw that rotates within the first groove, a slider fitted on the surface of the first lead screw that engages with a helical groove on the surface of the first lead screw, the slider being fixed within the U-shaped frame, and a first motor fixed to the side end of the base, the first motor being fixedly connected to the first lead screw via a coupling. The process involves starting the fourth motor to drive the polishing roller to rotate, which in turn drives the first motor to drive the first lead screw to rotate. The first lead screw then moves the U-shaped frame and the rotating polishing roller, thus polishing the nut.

[0010] Optionally, the loading and unloading assembly includes an electric push rod fixed to the side of the base, and the return frame is fixed to the output end of the electric push rod.

[0011] Optionally, the loading and unloading assembly further includes a fifth motor fixed inside the return frame, the fifth motor being fixedly connected to the loading frame via a coupling.

[0012] In this application, the third motor is started to drive the bidirectional lead screw to rotate. The bidirectional lead screw drives the two threaded blocks to move in the direction of approaching or moving away from each other, so that the four slide rods move in the direction of approaching or moving away from each other, thereby driving the two arc-shaped clamps to move in the direction of approaching or moving away from each other. When the two arc-shaped clamps move in the direction of moving away from each other, they externally expand and clamp the nut. By starting the second motor, the worm gear is driven, which in turn drives the worm wheel to rotate. The worm wheel can then drive the adjusting shaft to adjust the angle, making polishing easier. By starting the fourth motor to drive the polishing roller to rotate, which in turn drives the first motor to drive the first lead screw to rotate, and the first lead screw drives the U-shaped frame and the rotating polishing roller to move, the nut can be polished. After polishing, the electric push rod is activated to move the loading rack, placing the polished nuts into the receiving groove. The third motor is then activated to release the clamping force, causing the nuts to lose their clamping force on the surface of the adjusting shaft. The nuts are then stored in the receiving groove. Subsequently, the electric push rod drives the loading rack to reset, and the fifth motor drives the loading rack to rotate 180°, rotating the loaded nuts to the side closer to the adjusting shaft. The electric push rod is then activated to place multiple nuts onto the surface of the adjusting shaft, and the third motor is activated to clamp the nuts, thus polishing them. The polished nuts are then removed, and the nuts to be polished are installed.

[0013] In this utility model, the valve nut polishing equipment with automatic mechanical feeding function uses a third motor to drive the bidirectional lead screw to rotate, which drives two arc-shaped clamps to move away from each other, thereby achieving external clamping and fixing of the nut. This fixing method is firm and reliable, can adapt to valve nuts of different specifications and sizes, and ensures that the nut will not loosen or shift during the polishing process, thus improving the stability and quality of polishing. In this utility model, the valve nut polishing equipment with automatic mechanical feeding function has a worm gear transmission structure set in the vertical plate. The worm is driven to rotate by a second motor, which drives the worm gear and the adjusting shaft to adjust the angle. This allows the angle of the nut to be flexibly adjusted according to the shape of the nut and the polishing requirements during the polishing process, so that the polishing roller can polish the nut surface comprehensively and evenly, further improving the polishing quality.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] In the description of this utility model, it should be understood that the terms "opening", "upper", "middle", "length", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0020] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0021] In one embodiment: Please see Figures 1-4As shown, this embodiment provides a valve nut polishing device with an automatic mechanical feeding function, including a base 1, which serves as the supporting foundation for the entire device, with a vertical plate 8 fixed to its top. An adjusting shaft 14 is rotatably mounted inside the vertical plate 8, and the surface of the adjusting shaft 14 is used to fit and place the nut. A set of positioning components is provided inside the adjusting shaft 14, which are used to fix the nut to the surface of the adjusting shaft 14.

[0022] The positioning assembly includes a fourth groove 18 formed within the adjusting shaft 14, and two arc-shaped clamping plates 19 slidably mounted within the fourth groove 18. The arc surfaces of both arc-shaped clamping plates 19 are provided with anti-slip pads to increase friction with the nut and prevent slippage during polishing. Each of the two arc-shaped clamping plates 19 has a fifth groove 22, and two threaded blocks 21 slide within the fourth groove 18. A bidirectional lead screw 20 rotates within the fourth groove 18, and two sliders are fitted onto the surface of the bidirectional lead screw 20, engaging with the positive and negative helical grooves on its surface. The two sliders are respectively fixed within the two threaded blocks 21. Connecting rods 23 are fixed to the upper and lower ends of each of the two threaded blocks 21, and the four connecting rods 23 slide within the two fifth grooves 22. Each of the four connecting rods 23 has a sliding rod 24 fixed within it, and each of the two fifth grooves 22 has two sliding grooves 25, within which the four sliding rods 24 slide. A third motor 13 is fixed to the side end of the adjusting shaft 14. The third motor 13 is fixedly connected to the double-acting lead screw 20 via a coupling.

[0023] During operation, the third motor 13 is started, which drives the bidirectional lead screw 20 to rotate. The bidirectional lead screw 20 drives the two threaded blocks 21 to move in opposite directions, causing the four sliding rods 24 to move in opposite directions, thereby driving the two arc-shaped clamping plates 19 to move in opposite directions. When the two arc-shaped clamping plates 19 move in opposite directions, they externally clamp the nut sleeved on the surface of the adjusting shaft 14, firmly fixing the nut to the adjusting shaft 14.

[0024] A third groove 10 is formed inside the vertical plate 8, and a worm gear 11 rotates within the third groove 10. A worm wheel 12, which meshes with the worm gear 11, is fixed to the surface of the adjusting shaft 14. A second motor 9 is fixed to the side end of the vertical plate 8, and the second motor 9 is fixedly connected to the worm gear 11 via a coupling. When it is necessary to adjust the angle of the nut for easier polishing, the second motor 9 is started. The second motor 9 drives the worm gear 11 to rotate, the worm gear 11 drives the worm wheel 12 to rotate, and the worm wheel 12 drives the adjusting shaft 14 to adjust the angle, so that the nut is at a suitable polishing angle.

[0025] To facilitate loading and unloading onto the adjusting shaft 14, a second groove 3 is provided at the top of the base 1. A return frame 15 slides within the second groove 3, and a loading frame 16 rotates at the top of the return frame 15. The top of the loading frame 16 has two receiving slots, used to receive nuts to be polished and polished nuts, respectively. A loading and unloading assembly is provided between the base 1 and the second groove 3. The loading and unloading assembly includes an electric push rod 17 fixed to the side of the base 1, and the return frame 15 is fixed to the output end of the electric push rod 17. The loading and unloading assembly also includes a fifth motor fixed within the return frame 15, which is fixedly connected to the loading frame 16 via a coupling.

[0026] During loading and unloading operations, the electric push rod 17 extends and retracts, causing the return frame 15 to slide within the second groove 3, thus enabling the horizontal movement of the loading frame 16. The rotation of the fifth motor drives the loading frame 16 to rotate, causing the positions of the receiving grooves on the loading frame 16 for accommodating the nuts to be polished and the polished nuts to alternate. This facilitates the accurate placement of the nuts to be polished onto the adjusting shaft 14 and the removal of the polished nuts from the adjusting shaft 14, achieving automatic mechanical loading and unloading.

[0027] In another embodiment: Improvements based on Example 1: See Appendix Figure 1 -Appendix Figure 4 A valve nut polishing device with an automatic mechanical feeding function is disclosed. The base 1 has a first groove 2 at its top, and the first groove 2 contains a set of polishing components for polishing the nuts. The polishing components include a U-shaped frame 4 that slides within the first groove 2, and a polishing roller 6 that rotates within the U-shaped frame 4. A fourth motor is fixed to the side end of the U-shaped frame 4, and the fourth motor is fixedly connected to the polishing roller 6 via a coupling. A first lead screw 5 rotates within the first groove 2, and a slider that engages with a helical groove on the surface of the first lead screw 5 is fitted onto its surface. The slider is fixed within the U-shaped frame 4. A first motor 7 is fixed to the side end of the base 1, and the first motor 7 is fixedly connected to the first lead screw 5 via a coupling.

[0028] During polishing, the fourth motor is started, which drives the polishing roller 6 to rotate. At the same time, the first motor 7 is started, which drives the first lead screw 5 to rotate. The first lead screw 5 drives the U-shaped frame 4 and the rotating polishing roller 6 to move, so that the polishing roller 6 contacts the surface of the nut, thereby polishing the nut.
