Description

Technical Field

[0001] The utility model belongs to the field of metal processing, and in particular relates to a metal plate surface rust removal device. Background Art

[0002] During the production of metal plates, in order to improve the aesthetics and the strength, toughness and fatigue resistance of the metal plates, a grinding device is needed to remove rust and grind the surface of the metal plates.

[0003] A plate sander (CN2095735U) currently available consists of a flat plate with a handle, a grinding / polishing material wrapped around the plate, and an active pressure plate mechanism that secures the grinding / polishing material against the plate. Because this sander requires manual back-and-forth movement and constant pressure on the surface to be derusted, prolonged use can be tiring and inefficient.

[0004] However, the grinding heads on the existing handheld electric grinding and rust removal equipment mostly use round heads, which have a lower grinding range than the plate grinder. When grinding and rust removal on metal plates of the same size, it takes more time, which also causes the problem of low efficiency. Combining the above two points, a metal plate surface rust removal equipment is proposed to solve the above problems. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figure 1-6 Compared with the manual method used in the comparative document, the metal plate surface rust removal equipment in this embodiment is more convenient, quicker and more labor-saving to use. At the same time, compared with the existing handheld electric grinding and rust removal equipment, the grinding range is larger, which can improve the efficiency during use.

[0031] Specifically, it includes a housing 1;

[0032] A handle 2 is provided above the housing 1;

[0033] Switch 3, provided on handle 2;

[0034] The transmission member 4 is arranged inside the housing 1;

[0035] A servo motor 5 is disposed in the housing 1 and connected to the transmission member 4. The servo motor 5 is electrically connected to the switch 3. The switch 3 is used to control the on / off state of the servo motor 5.

[0036] A grinding member 6 is provided below the housing 1 and connected to the transmission member 4;

[0037] Two limiting members 7 are provided on the polishing member 6 and connected to the inner cavity of the housing 1;

[0038] The servo motor 5 drives the polishing member 6 to move back and forth through the transmission member 4 to polish and remove rust from the metal plate surface. The two limit members 7 are used to limit the movement of the polishing member 6.

[0039] In this embodiment, when time is needed, the handle 2 can be held in hand to fit the grinding piece 6 to the surface to be ground and rust removed on the metal plate, and then the switch 3 can be pressed. Under the action of the servo motor 5, the two transmission parts 4 drive the grinding piece 6 to move back and forth horizontally for automatic grinding and rust removal of the metal plate. The limit part 7 can limit and guide the moving direction of the grinding piece 6 during this process. Compared with the manual method adopted in the comparative document, the rust removal equipment is more convenient, faster and more labor-saving to use. At the same time, compared with the existing handheld electric grinding and rust removal equipment, the grinding range is larger, which can improve the efficiency during use.

[0040] Specifically, refer to Figure 3-4 The transmission member 4 includes two sector gears 41 rotatably arranged on the bottom wall of the inner cavity of the shell 1; two transmission wheels 42 are respectively arranged on the two sector gears 41, and the servo motor 5 is connected to one of the transmission wheels 42; the two transmission wheels 42 are connected to each other through a transmission belt 43.

[0041] Specifically, refer to Figure 2-5 The grinding part 6 includes a carrying plate 61 arranged above the shell 1; a double-sided tooth plate 62 arranged on the carrying plate 61, and the double-sided tooth plate 62 is engaged with one of the transmission wheels 42; a sandpaper 63 is arranged below the carrying plate 61 and its two ends extend to both sides of the carrying plate 61; two clamping plates 64 are respectively arranged on both sides of the carrying plate 61 and clamp the two ends of the sandpaper 63; two fixing screws 65 are provided on the side of the clamping plate 64 away from the carrying plate 61, and the fixing screws 65 pass through the clamping plate 64 and are threadedly connected to the carrying plate 61.

[0042] In this embodiment, when the servo motor 5 is powered on, it can drive one of the sector gears 41 and the transmission wheel 42 to rotate, and at the same time, the sector gear 41 on the other side is driven by the transmission belt 43 and the other transmission wheel 42 to rotate in the same direction. When one of the sector gears 41 contacts the double-sided toothed plate 62, it can drive the double-sided toothed plate 62 to move to one side. When the sector gear 41 is about to leave the contact with the double-sided toothed plate 62, the other sector gear 41 is engaged and drives the double-sided toothed plate 62 to move in the same direction. This reciprocating process can drive the double-sided toothed plate 62, the carrying plate 61 and the sandpaper 63 to move back and forth. During this process, the sandpaper 63 continuously rubs against the metal plate surface, thereby grinding and removing rust from the metal plate surface.

[0043] When the sandpaper 63 needs to be replaced, each fixing screw 65 can be screwed in the reverse direction to remove the clamping plate 64. Then, after replacing the new sandpaper 63, the above steps can be reversed to clamp and fix the sandpaper 63 with the clamping plate 64, completing the replacement process of the sandpaper 63.

[0044] Specifically, refer to Figure 3-4The limiting member 7 includes two support plates 71 arranged on the double-sided tooth plate 62; a sliding rod 72 arranged between the two support plates 71; a support column 73 slidably sleeved on the outer wall of the sliding rod 72, and the support column 73 is connected to the top wall of the inner cavity of the shell 1.

[0045] In this embodiment, when the double-sided tooth plate 62 and the supporting plate 61 move, the support plate 71 and the sliding rod 72 slide inside the support column 73. Through the sliding cooperation between the sliding rod 72 and the support column 73, the double-sided tooth plate 62 and the supporting plate 61 can be limited and guided.

[0046] Specifically, refer to Figure 4 A plurality of balls 8 are provided on the inner wall of the support column 73 , and the balls 8 slide and fit with the outer wall of the slide rod 72 .

[0047] In this embodiment, the ball bearing 8 can effectively reduce the friction between the sliding rod 72 and the support column 73, thereby improving the smoothness of sliding between the two and reducing the feeling of obstruction.

[0048] Specifically, refer to Figure 5 A rubber pad 9 is provided on one side of the clamping plate 64 close to the sandpaper 63 .

[0049] In this embodiment, the rubber pad 9 can increase the friction between the clamping plate 64 and the sandpaper 63. Not only can the elasticity of the rubber pad 9 make the clamping surface more comprehensive, but it can also increase the friction and improve the clamping and fixing effect.

[0050] Specifically, refer to Figure 3-4 The transmission wheel 42 is a concave toothed synchronous wheel, and the transmission belt 43 is a toothed synchronous belt.

[0051] In this embodiment, the transmission wheel 42 is a concave toothed synchronous wheel and the transmission belt 43 is a toothed synchronous belt. In actual use, this leads to a better transmission effect and avoids the phenomenon of the two sector gears 41 being out of sync.

[0052] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
