[0029] See also Figures 1 to 5 , the utility model provides a technical solution:

[0030] A grinding device for producing metal junction boxes, comprising an operating table 1, a longitudinal moving module 2 is arranged on the top surface of the operating table 1, a transverse moving module 3 is arranged at the output end of the longitudinal moving module 2, an electric push rod 4 is bolted to the output end of the transverse moving module 3, a mounting block 5 is fixedly connected to the output end of the electric push rod 4, a grinding motor 6 is arranged in the middle of the mounting block 5, a grinding disc 7 is fixedly connected to the output end of the grinding motor 6, a clamping mechanism 8 for easy flipping is arranged on the top surface of the operating table 1, and a cleaning and cooling component 9 is arranged on the side wall of the mounting block 5;

[0031] The clamping mechanism 8 includes a support frame 81, a rotating shaft 82, a mounting plate 83, an electric push rod 2 84, a clamping plate 85, a gear 86, an electric push rod 3 87, a connecting plate 88, a rack 89 and a limit assembly 810. The two support frames 81 are bolted to the top surface of the operating table 1, the rotating shaft 82 is connected to the middle of the support frame 81 by a bearing, the mounting plate 83 is fixedly connected to one end of the rotating shaft 82, the electric push rod 2 84 is bolted to the side wall of the mounting plate 83, the clamping plate 85 is fixedly connected to the output end of the electric push rod 2 84, the gear 86 is fixedly connected to one end of the rotating shaft 82, the electric push rod 3 87 is arranged on the side wall of the operating table 1, the connecting plate 88 is fixedly connected to the output end of the electric push rod 3 87, the two racks 89 are respectively fixedly connected to the two ends of the connecting plate 88, the rack 89 is meshed with the gear 86, and the limit assembly 810 is arranged on the top surface of the operating table 1 for guiding and limiting the movement of the rack 89.

[0032] Specifically, Figure 5 As shown, the limiting assembly 810 includes a limiting bar 8101 and a limiting frame 8102 . The limiting bar 8101 is fixedly connected to the side wall of the rack 89 , and the limiting frame 8102 is fixedly connected to the top surface of the operating table 1 . The limiting bar 8101 and the limiting frame 8102 are movably connected.

[0033] Specifically, Figure 4 As shown, a support ring 10 is fixedly connected to the side wall of the support frame 81 , and a limit ring 11 is fixedly connected to the side wall of the mounting plate 83 . The limit ring 11 is movably connected to the support ring 10 .

[0034] Specifically, Figure 4 As shown, four guide cylinders 12 are fixedly connected to the side wall of the mounting plate 83 , and four guide rods 13 are fixedly connected to the side wall of the clamping plate 85 . The guide rods 13 are movably connected to the guide cylinders 12 .

[0035] Specifically, Figure 4 As shown, an anti-skid pad 14 is bonded to the side wall of the clamping plate 85 , and an anti-scratch pattern is provided on the side wall of the anti-skid pad 14 .

[0036] Specifically, Figure 4 As shown, a plurality of supporting rollers 15 are provided in the middle of the limiting frame 8102 , and the supporting rollers 15 are in contact with the limiting strips 8101 .

[0037] When in use, the electric push rod 14 can be driven to move by the horizontal moving module 3 and the vertical moving module 2, and the metal junction box is placed in the middle of the two clamping plates 85, and the two electric push rods 3 87 are controlled to start at the same time so that the clamping plates 85 clamp the metal junction box. The setting of the anti-skid pad 14 can prevent sliding between the clamping plates 85 and the junction box. The power is connected to start the grinding motor 6, and the electric push rod 14 pushes the grinding motor 6 to move so that the grinding disc 7 grinds and polishes the metal junction box. When one side of the square metal junction box is polished, the electric push rod 14 pulls the grinding motor 6 to move upward within a certain range. At this time, the electric push rod 3 87 pushes the rack 89 to mesh with the gear 86, and the rack 89 drives the gear 86 to rotate. The other side of the metal junction box is vertically upward, and this side can be polished at this time. During this process, the limit bar 8101 and the limit frame 8102 can guide and limit the movement of the rack 89. The setting of the support roller 15 can reduce the friction between the limit bar 8101 and the limit frame 8102. The support ring 10 and the limit ring 11 can increase the connection strength between the support frame 81 and the mounting plate 83. The movement of the clamping plate 85 can be guided by the guide rod 13 and the guide cylinder 12. In this way, the square junction box can be clamped and fixed quickly, and the junction box can be rotated in the direction after clamping and fixing. After polishing one side of the junction box, the junction box can be turned over and polished, thereby improving the polishing efficiency of the metal junction box.

[0038] Specifically, Figure 3 As shown, the cleaning and cooling assembly 9 includes a cleaning pipe 91 and a connector 92. The cleaning pipe 91 is fixedly connected to one side of the mounting block 5. The cleaning pipe 91 is inclined. The connector 92 is disposed at the top of the cleaning pipe 91. The connector 92 is connected and cooperated with an external air pump.

[0039] Specifically, Figure 3 As shown, a cleaning and collecting cover 16 is provided in the middle of the operating platform 1 .

[0040] The cleaning tube 91 is connected to the external air pump via the connector 92, and the external air pump delivers high-pressure gas to the cleaning tube 91 via the connector 92. The gas is delivered to the grinding wheel 7 and the metal junction box, which can cool the grinding wheel 7 and blow off the debris and dust attached to the grinding wheel and the metal junction box.

[0041] By adopting the above technical solution, the problem that the existing junction box body surface processing and polishing device is inconvenient to turn over the junction box for grinding and polishing is solved. When grinding the outer wall of the existing square junction box, the square junction box is usually clamped and fixed for grinding, and then disassembled and clamped for grinding after completion, which leads to low grinding and polishing efficiency of the junction box.

[0042] Working principle: When the present application is used, the metal junction box is first placed in the middle of the two clamping plates 85, and the two electric push rods 3 87 are controlled to start at the same time so that the clamping plates 85 clamp the metal junction box. The setting of the anti-skid pad 14 can prevent sliding between the clamping plates 85 and the junction box. The power is connected to start the grinding motor 6, and the electric push rod 1 4 pushes the grinding motor 6 to move so that the grinding disc 7 grinds and polishes the metal junction box. When one side of the square metal junction box is polished, the electric push rod 1 4 pulls the grinding motor 6 to move upward within a certain range. At this time, the electric push rod 3 87 pushes the rack 89 to mesh with the gear 86, and the rack 89 drives the gear 86 to rotate. Movement makes the other side of the square metal junction box point vertically upward, and this side can be polished at this time. The cleaning tube 91 is connected to the external air pump through the connector 92. The external air pump delivers high-pressure gas to the cleaning tube 91 through the connector 92. The gas is delivered to the grinding disc 7 and the metal junction box, which can cool the grinding wheel and blow off the debris and dust attached to the grinding disc 7 and the metal junction box. In this way, the square junction box can be quickly clamped and fixed, the junction box can be rotated in the direction after clamping and fixing, and the junction box can be turned over and polished after polishing one side of the junction box, thereby improving the polishing efficiency of the metal junction box.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
