After the grinding disc is started, the edge where the punched burrs of the accessory plate are located is controlled to contact the grinding surface of the grinding disc one by one to achieve the grinding of the burrs on the accessory plate. However, the operation efficiency of this single-sided burr grinding is low, which leads to the low production efficiency of the accessory plate.
[0004] Therefore, a burr removal device for hardware accessories is proposed to address the above problems. Utility Model Content

[0022] 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.
[0023] Specific implementation examples are given below.
[0024] Please see Figure 1 - Figure 4 This utility model provides a hardware accessory burr grinding device, including a base plate 1, an accessory plate 2 placed on the top surface of the base plate 1, a grinding assembly 3 above the accessory plate 2, the grinding assembly 3 including a telescopic sleeve 31, with grinding discs 32 installed at both ends of the telescopic sleeve 31, the grinding surfaces of the two grinding discs 32 respectively contacting the top two sides of the accessory plate 2, a first gear 311 fixedly connected to the outer center of the telescopic sleeve 31, lifting rings 321 fixedly connected to the adjacent side walls of the two grinding discs 32 by brackets, a lifting assembly 4 arranged between the two lifting rings 321, a lifting plate 5 arranged above the lifting assembly 4, an electric telescopic rod 51 fixedly connected to the corner of the lifting plate 5 by brackets, one end of each of the four electric telescopic rods 51 being vertically fixedly connected to the top of the base plate 1, and the accessory plate 2 being placed on the base plate 1. Between the bottom surfaces, it can be pushed to pass through the coverage area of the grinding component 3. The two grinding discs 32 of the grinding component 3 are installed at both ends of the telescopic sleeve 31. This allows the rotation of the telescopic sleeve 31 to control the synchronous rotation of the two grinding discs 32. When the two grinding discs 32 come into contact with the edge of the accessory plate 2 during the movement, the device can grind and remove the burrs of the accessory plate 2. Through the linkage between the lifting component 4, the lifting plate 5 and the lifting ring 321, the lifting plate 5 can be installed on the grinding component 3. The lifting plate 5 is fixed to the top of the bottom plate 1 by the electric telescopic rod 51. This allows the relative height of the lifting plate 5 and the grinding component 3 to be controlled within a certain range by extending and retracting the electric telescopic rod 51, so as to adapt to the change in the relative thickness of the accessory plate 2.
[0025] like Figure 2 , Figure 3 and Figure 4 As shown, the hoisting assembly 4 includes two racks 41 and a central gear 42. The shaft of the central gear 42 is fixedly connected to the bottom center of the hoisting plate 5. Both racks 41 mesh with the central gear 42. The two racks 41 are rotationally symmetrical along the axis of the central gear 42. One end of the rack 41 is fixedly connected to an L-shaped bracket 43. A clamp 431 is fixedly connected to one side of the L-shaped bracket 43. The clamp 431 and the hoisting ring 321 are mutually engaged. The central gear 42 is fixed to the bottom surface of the hoisting plate 5. Under the linkage of the central gear 42, the two racks 41 can move synchronously in opposite directions. The central gear 42 is engaged with the hoisting ring 321 through the clamp 431 on the L-shaped bracket 43. This allows the two grinding discs 32 to move synchronously in opposite directions relative to each other, so as to adapt to the change of the relative spacing of the grinding edges of the accessory plate 2 within a certain range and ensure the grinding effect of the grinding discs 32.
[0026] like Figure 2 , Figure 3 and Figure 4 As shown, a limiting rail 411 is provided on the side wall of the rack 41, and a hoisting rail 44 is slidably installed between the inner walls of the limiting rail 411. The top of the hoisting rail 44 is fixedly connected to the bottom surface of the hoisting plate 5. The rack 41 and the hoisting rail 44 installed on the bottom surface of the hoisting plate 5 are mutually engaged through the limiting rail 411. While not hindering the relative movement of the rack 41, the hoisting plate 5 can directly hoist the rack 41, increasing the rationality of the device structure.
[0027] like Figure 1 and Figure 3 As shown, elastic retractable rods 52 are fixed to both sides of the lifting plate 5. One end of each elastic retractable rod 52 is fixed to the side wall of the L-shaped bracket 43 through a bracket. Under the elastic retractable force of the elastic retractable rods 52, the L-shaped brackets 43 on both sides have an elastic force that brings them closer to each other, thereby providing the pressing force for the grinding disc 32 and the burr edge of the accessory plate 2 to contact the horizontal surface.
[0028] like Figure 4 As shown, each nested sleeve of the telescopic sleeve 31 is provided with a limit bar 312 on its outside.
[0029] During operation, the setting of the limit bar 312 ensures that the various branch pipes do not rotate relative to each other while the telescopic sleeve 31 is extending and retracting, thereby allowing the grinding discs 32 installed at both ends of the telescopic sleeve 31 to rotate synchronously with the first gear 311.
[0030] like Figure 2 and Figure 3As shown, a motor 6 is suspended from the bottom of the lifting plate 5 by a bracket. The output shaft of the motor 6 is fixedly connected to a second gear 61. The second gear 61 meshes with the first gear 311. The motor 6 is suspended below the lifting plate 5 and provides output force for the overall rotation of the first gear 311, the telescopic sleeve 31, and the grinding disc 32 through the meshing of the second gear 61 and the first gear 311.
[0031] Working principle: The accessory plate 2 is placed between the bottom surfaces of the base plate 1 and can be pushed to pass through the coverage area of the grinding assembly 3. The two grinding discs 32 of the grinding assembly 3 are installed at both ends of the telescopic sleeve 31. This allows the rotation of the telescopic sleeve 31 to control the synchronous rotation of the two grinding discs 32. When the two grinding discs 32 come into contact with the edge of the accessory plate 2 during the movement, the device grinds and removes the burrs of the accessory plate 2. The setting of the limit strip 312 ensures that the individual pipes do not rotate relative to each other while the telescopic sleeve 31 is extending and retracting. Through the linkage between the lifting assembly 4, the lifting plate 5, and the lifting ring 321, the lifting plate 5 is used to install the grinding assembly 3. The lifting plate 5 is fixed to the top of the base plate 1 by the electric telescopic rod 51. This allows the height of the lifting plate 5 and the grinding assembly 3 to be controlled within a certain range by extending and retracting the electric telescopic rod 51, adapting to changes in the relative thickness of the accessory plate 2. The central gear 42 is fixed to the lifting assembly 3. Under the linkage of the central gear 42, the two racks 41 on the bottom surface of the mounting plate 5 can move synchronously in opposite directions. The central gear 42 is engaged with the lifting ring 321 via the clamp 431 on the L-shaped bracket 43. This allows the two grinding discs 32 to move synchronously in opposite directions relative to each other, adapting to changes in the relative spacing of the grinding edges of the accessory plate 2 within a certain range, ensuring the grinding effect of the grinding discs 32. The racks 41 are engaged with the lifting rail 44 installed on the bottom surface of the lifting plate 5 via the limit rail 411. While not hindering the relative movement of the rack 41, the rack 41 is directly hoisted by the hoisting plate 5. Under the elastic contraction force of the elastic contraction rod 52, the L-shaped brackets 43 on both sides have an elastic force that brings them closer together, thereby providing the pressing force for the grinding disc 32 and the burr edge of the accessory plate 2 to contact the horizontal surface. The motor 6 is hoisted below the hoisting plate 5 and provides output force for the overall rotation of the first gear 311, the telescopic sleeve 31 and the grinding disc 32 through the mutual meshing of the second gear 61 and the first gear 311.
[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
