[0024] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.
[0025] Reference Figure 1-3 As shown, a device for deburring the surface of a metal product comprises a handle 1, a motor 2 disposed at the bottom end of the handle 1, and a grinding disc 3 mounted on the output shaft of the motor 2;
[0026] When in use, the handle 1 is manually held and the motor 2 is turned on, and the output shaft of the motor 2 drives the grinding disc 3 to rotate continuously, so that the rotating grinding disc 3 moves on the side of the surface of the metal product, thereby effectively grinding and removing burrs.
[0027] However, in practice, when the handle 1 is manually operated, it is often difficult to ensure that the pressure of the handle 1 is balanced when walking, and the handle 1 is over-pressed, so that the grinding disc 3 is in excessive contact with the surface of the metal product, which seriously causes the metal product to be over-grinded and affects the flatness of the surface;
[0028] For this purpose, refer to Figure 1 and Figure 2As shown, it is worth noting that it also includes a horizontal pressure mechanism for maintaining a constant contact force between the grinding disc 3 and the metal product;
[0029] The horizontal pressing mechanism includes three sets of telescopic support rods distributed around the outer circumference of the grinding disc 3, and the telescopic support rods are composed of an internal threaded tube 4 vertically arranged beside the handle 1 and a positioning column 5 slidably arranged below the internal threaded tube 4;
[0030] A fixed bracket 7 is tightly sleeved on the rod body of the internal threaded tube 4 in one group of telescopic support rods, and the fixed bracket 7 is fixedly connected to the outer wall of the handle 1. The internal threaded tube 4 in the other two groups of telescopic support rods are tightly sleeved on the rod body of the internal threaded tube 4, and the movable bracket 8 is slidably connected to the outer wall of the handle 1.
[0031] By setting the telescopic support rod, when the handle 1 is held and the grinding disc 3 is used to grind the side part of the metal surface, the positioning column 5 in the telescopic support rod contacts the processing table, and then the three groups of telescopic support rods cooperate with each other to effectively form a positioning and supporting effect for the handle 1, keep the height of the handle 1 constant during grinding, and keep the pressure applied by the grinding disc 3 on the metal product constant, so as to avoid excessive contact between the grinding disc 3 and the surface of the metal product, resulting in excessive grinding of the metal product and affecting the flatness of the surface.
[0032] Further, refer to Figure 1 and Figure 2 As shown, it is worth noting that the inner side of the internal threaded barrel 4 is threadedly connected with a push-pull screw 11 fixedly connected to the top of the positioning column 5;
[0033] By setting the push-pull screw 11 and turning the knob to push and pull the screw 11, the push-pull screw 11 can be retracted into the inner side of the internal threaded tube 4 under the threaded structure, and then the positioning column 5 can be pushed and pulled to slide up and down. This facilitates the rapid adjustment of the overall length of the positioning column 5 and the internal threaded tube 4 according to the thickness of the side of the metal product to be processed, so that the positioning column 5 can contact the processing table when grinding metal products of different thicknesses, thereby enhancing practicality and scope of use.
[0034] Further, refer to Figure 1 and Figure 2 As shown, it is worth noting that a ball 6 is rotatably embedded at the bottom end of the positioning column 5;
[0035] By providing the ball bearings 6 , when the positioning column 5 contacts the processing table, the contact area between the positioning column 5 and the processing table can be effectively reduced, thereby reducing the friction force of the positioning column 5 when it moves on the processing table.
[0036] In addition, refer to Figure 1 and Figure 2 As shown, it is worth noting that it also includes a circumferential sealing mechanism for protecting the grinding disc 3;
[0037] The circumferential sealing component includes a fixed guard ring 9 clamped on the outer circumference of the grinding disc 3 and two movable guard rings 10 symmetrically slidably arranged on the outer wall of the fixed guard ring 9, the fixed guard ring 9 is fixedly connected to the internal threaded tube 4 in one group of telescopic support rods through a connecting block, and the two movable guard rings 10 are correspondingly fixedly connected to the internal threaded tubes 4 in the other two groups of telescopic support rods through connecting blocks;
[0038] By setting the circumferential sealing component, when the grinding of the metal product is completed, the two groups of telescopic support rods are slid around the outer wall of the handle 1 respectively, so that the two groups of telescopic support rods are parallel, and the two movable guard rings 10 are merged in the same way. Then the two movable guard rings 10 cooperate with the fixed guard ring 9 to effectively seal and protect the outer periphery of the grinding disc 3 to prevent the grinding disc 3 from being damaged by bumps during the transportation and carrying of the handle 1.
[0039] Further, refer to Figure 1 and Figure 3 As shown, it is worth noting that a notch 12 is provided at one end of the movable bracket 8 relative to the handle 1, a connecting tooth plate 13 fixedly connected to the outer wall of the handle 1 is provided in the notch 12, and guide grooves 14 are provided at both ends of the connecting tooth plate 13, and a sliding column fixedly connected to the inner wall of the notch 12 is slidably provided in the guide groove 14;
[0040] By setting the connecting tooth plate 13, the guide groove 14 and the sliding column, when the telescopic support rod is movable, the movable bracket 8 can slide synchronously along the outer wall of the connecting tooth plate 13, and then the sliding column can slide synchronously inside the guide groove 14. In this way, the guide groove 14 cooperates with the sliding column to effectively limit the moving trajectory of the movable bracket 8 and the telescopic support rod.
[0041] Further, refer to Figure 3 As shown, it is worth noting that a control groove 15 is provided on the inner wall of the innermost side of the notch 12, and a positioning card is provided in the control groove 15;
[0042] The positioning clamp includes a transmission screw 18 vertically rotatably arranged on the innermost inner wall of the control groove 15 and a movable seat 16 threadedly sleeved on the end of the transmission screw 18, and a positioning clamp 17 is fixed to the end of the movable seat 16 away from the transmission screw 18, and the end of the positioning clamp 17 penetrates between two adjacent teeth of the connecting tooth plate 13, and the outer wall of the movable seat 16 is slidably connected with the inner wall of the control groove 15;
[0043] A control rod 19 is provided on one side of the movable bracket 8. The control rod 19 rotates and penetrates into the control slot 15 and is tightly sleeved with a first bevel gear 20. A second bevel gear 21 meshing with the first bevel gear 20 is tightly sleeved on the rod body of the transmission screw 18.
[0044] After the sliding of the telescopic support is completed, the knob control rod 19 is immediately turned, and the first bevel gear 20 can mesh with the second bevel gear 21 as the control rod 19 continues to rotate, and then the transmission screw 18 is rotated, so that the movable seat 16 slides inside the control groove 15 under the threaded structure, and the positioning block 17 penetrates between two adjacent teeth of the guide groove 14, thereby locking the movable telescopic support rod to ensure its stability.
