[0030] Embodiments
[0031] Please refer to Figures 1-6 , the embodiment provides a handheld self-weight polishing tool, including drive device 1, fixed tool 2 and abrasive belt 5, fixed tool 2 is equipped with clamping plate 3, clamping plate 3 is equipped with open vertical downward clamping groove 4;Fixed tool 2 rotationally provided with driving roller 6 and driven wheel 7, abrasive belt 5 is wound on driving roller 6 and driven wheel 7 respectively, the bottom of abrasive belt 5 is polishing surface and is horizontally arranged;Drive device 1 is in transmission connection with driving roller 6.The drive device 1 of the embodiment is preferably a pneumatic drive device, such as a pneumatic motor and other existing products. In actual manufacture, the parts of mature polishing equipment on the market are used for modification. The drive device 1 uses the pneumatic drive handle used in FS30 air grinder, which can realize transmission through gear and driving roller 6. The driving is realized by pneumatic mode, and there is no need to worry about the dust erosion problem in polishing workshop. The number of clamping plates 3 in the embodiment is two and is arranged at intervals, and the planes where the two clamping plates 3 are located are perpendicular to each other.
[0032] In use, as Figure 5 shown, the polishing tool is installed on the battery tray box body 14, wherein the welding bead polishing area is at the top of the connection between the two sides of the battery tray box body 14, the two clamping plates 3 are vertically clamped on the two sides of the battery tray box body 14 through the clamping grooves 4 respectively, and the polishing surface at the bottom of the abrasive belt 5 abuts against the polishing area at the top of the battery tray box body 14. At this time, the polishing tool as a whole can slide in the vertical direction under the action of gravity.
[0033] The pneumatic driving device is connected with a gas source to supply gas, and the driving roller 6 is driven to rotate by the pneumatic driving device at this time, and the outer wall of the driving roller 6 in the embodiment is rough, so that the friction between the driving roller 6 and the abrasive belt 5 can be improved. The driving roller 6 rotates to drive the abrasive belt 5 to rotate along the driven wheel 7, and the abrasive belt 5 rotating in this way continuously rubs and grinds the grinding area of the weld on the top of the battery tray box 14, so that the efficiency of the weld grinding is improved and the labor cost is reduced by replacing manual work with small semi-automatic equipment.
[0034] The small and self-weight grinding form of the product can ensure that the grinding surface is always parallel to the surface to be ground, and a stable flat grinding effect is formed; and the small design of the equipment enables workers to simultaneously operate a single or multiple grinding equipment on a single battery tray box 14, and other complex areas can be ground while the equipment is running.
[0035] Optionally, the height of the top of the clamping groove 4 is lower than the height of the bottom grinding surface of the abrasive belt 5, so that a self-limiting structure is formed, and when the grinding process is performed, the grinding tool gradually automatically slides downward, and the top of the clamping groove 4 can contact the top of the battery tray box 14 first, so that the grinding tool does not continue to slide downward when the top of the clamping groove 4 contacts the top of the battery tray box 14, and the abrasive belt 5 is idling at this time, so that the over-grinding condition is avoided.
[0036] As shown in Figures 1-6 In some embodiments of the utility model, the clamping plate 3 is provided with a counterweight 8. It also includes a locking bolt 9 and a locking nut 10, and the locking bolt 9 passes through the clamping plate 3 and the counterweight 8 and is threadedly connected with the locking nut 10.
[0037] The utility model discloses a counterweight 8, which can complete the pressure of the grinding direction through the self-weight of the grinding tool + the counterweight 8, and the counterweight 8 on both sides can complete the equalization of the weld grinding height by using the self-weight when the equipment is performing the grinding operation, which has obvious advantages in efficiency compared with the height detection of the grinding robot. Moreover, the locking bolt 9 and the locking nut 10 are arranged, so that the counterweight 8 can be disassembled and replaced, and the semi-automatic grinding can be realized by adjusting the weight of the counterweight.
[0038] As shown in Figures 1-6 In some embodiments of the utility model, the number of driven wheels 7 is two and is arranged at intervals, the fixed tool 2 is rotationally provided with a tensioning wheel 11, and the abrasive belt 5 is wound on the tensioning wheel 11.
[0039] The utility model discloses a tensioning wheel 11 and two driven wheels 7, as shown in Figure 4As shown, two driven wheels 7 are located on the right side and are arranged in an upper and lower interval, the driving roller 6 and the tensioning wheel 11 are located on the left side, and the tensioning wheel 11 is located above the driving roller 6, so that the abrasive belt 5 is taut, and the abrasive belt 5 is facilitated to carry out the polishing work.
[0040] As Figures 1-6 As shown, in some embodiments of the utility model, the tensioning wheel 11 and the fixed tool 2 are provided with a rotating rod 12 in the shape of L, the middle part of the rotating rod 12 is rotatably arranged on the fixed tool 2, and the one end of the rotating rod 12 and the fixed tool 2 are provided with a tension spring 13, and the tensioning wheel 11 is rotatably arranged on the other end of the rotating rod 12. Figure 4 As shown, the tension spring 13 exerts a leftward pulling force on the bottom of the rotating rod 12, at this time, the tensioning wheel 11 at the left end of the rotating rod 12 can be moved upward and tightly abuts on the abrasive belt 5, so that the abrasive belt 5 is taut.
