Description

Technical Field

[0001] This utility model relates to the technical field of metal sheet grinding devices, and in particular to a grinding device for welding sheet metal. Background Technology

[0002] When welding metal sheets, two sheets need to be joined together, and the joint needs to be welded. Welding will leave weld scars on the sheet surface. To improve the smoothness of the sheet surface, the weld scars need to be ground after welding to ensure the surface is free of protrusions. During the grinding process, the sheet is first fixed in place, and workers typically use hand-held grinding tools to polish the weld scars. After grinding one side of the sheet, the sheet is flipped over, and the un-ground side is ground to ensure both sides are smooth and free of protrusions.

[0003] In practice, existing plate weld scar grinding methods typically involve grinding one side and then replacing the grinding surface, which is inefficient and the resulting debris can easily fly onto workers, increasing the safety factor of the grinding operation. Therefore, this application proposes a grinding device for plate welding that can improve grinding efficiency and increase the safety factor of the grinding operation. Utility Model Content

[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] Example

[0033] like Figure 1 , Figure 4 and Figure 5As shown, this utility model proposes a grinding device for plate welding, including a base 1, a support frame 3 fixedly installed on the top of the base 1, a plate positioning frame 7 movably installed on the support frame 3, and a metal plate 9 inserted into the plate positioning frame 7. The plate positioning frame 7 clamps and fixes the metal plate 9, improving the stability of the metal plate 9 during grinding. Two motor mounting frames 8 are movably installed on the support frame 3, and a first motor 2 is fixedly installed on the motor mounting frame 8. A grinding disc is fixedly installed at the output end of the first motor 2. The metal plate 9 is positioned between the two grinding discs. By driving the grinding discs to rotate through the first motor 2, the weld scars at the weld seam of the metal plate 9 can be ground. The method of using double-sided synchronous grinding can improve grinding efficiency. An L-shaped frame plate 82 is movably mounted on the motor mounting bracket 8. The first motor 2 is fixedly mounted on the L-shaped frame plate 82. When the L-shaped frame plate 82 is pushed to one side of the metal plate 9, the grinding disc can contact the weld scar on the metal plate 9, ensuring the grinding effect. A tempered glass 821 is fixedly mounted on the L-shaped frame plate 82. The tempered glass 821 is set on one side of the weld on the metal plate 9. The position of the weld scar can be observed through the tempered glass 821, which makes it easy to align the grinding disc with the weld scar. The L-shaped frame plate 82 can also shield the debris that flies during welding, preventing debris from flying onto the workers and effectively improving the safety factor of the grinding operation.

[0034] like Figures 1-4 As shown, to facilitate lateral adjustment of the motor mounting bracket 8, two side plates 6 are fixedly installed on both sides of the support frame 3 that are far apart. Several guide rods 61 are fixedly installed between the two side plates 6 on the same side. The motor mounting bracket 8 includes a first slide 81 and a second slide 83. The first slide 81 and the second slide 83 are movably installed on the matching guide rods 61 to ensure that the motor mounting bracket 8 can be laterally adjusted along the guide rods 61. When it is necessary to fix the metal plate 9 on the plate positioning bracket 7, the two motor mounting brackets 8 are moved to the left or right side of the support frame 3 to avoid obstructing the installation of the metal plate 9 and improve the convenience of installing and fixing the metal plate 9.

[0035] Furthermore, two longitudinal connecting plates 84 are fixedly installed between the first slide 81 and the matching second slide 83. The top of the L-shaped frame plate 82 is cut with a long strip opening 822. The aforementioned longitudinal connecting plates 84 pass through the matching long strip opening 822 and are movably connected to it. A support plate 841 is fixedly installed on the aforementioned longitudinal connecting plate 84. The support plate 841 is set at the bottom of the transverse plate part of the L-shaped frame plate 82 and can support the L-shaped frame plate 82. When the L-shaped frame plate 82 is pushed to move towards the metal plate 9, the aforementioned longitudinal connecting plates 84 move relative to each other inside the long strip opening 822, which improves the stability of the connection between the L-shaped frame plate 82 and the motor mounting bracket 8.

[0036] Secondly, a limiting rod 823 is fixedly installed on the longitudinal plate part of the L-shaped frame plate 82. One end of the limiting rod 823 is inserted into the slot carved on the second slide block 83 and is movably connected to it, ensuring that the bottom of the L-shaped frame plate 82 can be stably connected to the second slide block 83 as one unit, effectively improving the stability of the L-shaped frame plate 82 when it is pushed laterally.

[0037] like Figure 1 and Figure 5 As shown, to facilitate clamping and positioning of the metal sheet 9, the sheet positioning frame 7 includes two lifting plates 71. Each lifting plate 71 is movably mounted on the inner wall of the support frame 3. Two horizontal adjusting rods 72 are fixedly mounted on each lifting plate 71. A horizontal adjusting plate 73 is movably mounted on each of the two horizontal adjusting rods 72 in the same group. Two connecting rods 75 are fixedly mounted on each of the two connecting rods 75 in the same group. A sheet insert plate 74 is fixedly mounted on one end of each connecting rod 75. One end of the metal sheet 9 is inserted into one of the sheet insert plates 74, and then the other sheet insert plate 74 is horizontally adjusted. Adjustment is performed by pushing the horizontal adjustment plate 73, which in turn pushes the plate insert plate 74 toward one side of the metal plate 9. Once both ends of the metal plate 9 are inserted into the matching plate insert plate 74, the metal plate 9 can be clamped and positioned horizontally. The top of the plate insert plate 74 is bolted with a clamping seat 77. After the clamping seat 77 is fixed to the top of the plate insert plate 74, the top corners of the metal plate 9 can be locked and fixed, and its vertical position is limited. When clamping and positioning the metal plate 9, it is not only convenient to operate, but also ensures the firmness of clamping and fixing.

[0038] Furthermore, to facilitate vertical adjustment of the metal sheet 9, a longitudinal adjustment rod 76 is fixedly installed at the top of the lifting plate 71. The tops of both longitudinal adjustment rods 76 pass through the support frame 3 and are movably connected to it. A transverse connecting plate 78 is fixedly installed at the top of both longitudinal adjustment rods 76, and the transverse connecting plate 78 is mounted above the support frame 3. A suspension 4 is fixedly installed at the top of the support frame 3, and a second motor 5 is fixedly mounted on the suspension 4. A reciprocating screw 51 is fixedly installed at the output end of the second motor 5. The bottom end of the reciprocating screw 51 passes through the transverse connecting plate 78 and is threadedly connected to it. When the second motor 5 drives the reciprocating screw 51 to rotate, it can drive the transverse connecting plate 78 and the entire sheet positioning frame 7 to move vertically, facilitating vertical adjustment of the metal sheet 9.

[0039] Secondly, a sleeve is fixedly installed at the top of the aforementioned support frame 3, and the bottom end of the reciprocating screw 51 is inserted into the sleeve and movably connected to it. The sleeve limits the end of the reciprocating screw 51 away from the second motor 5, which can prevent the reciprocating screw 51 from shaking and effectively improve its stability during rotation.

[0040] In this embodiment, the metal plate 9 is first clamped and positioned. The motor mounting bracket 8 is moved to both sides of the support frame 3 to ensure that there are no obstructions on both sides of the plate insert plate 74. One end of the metal plate 9 is inserted into the corresponding plate insert plate 74. The other plate insert plate 74 is adjusted laterally. When both sides of the bottom of the metal plate 9 are inserted into the matching plate insert plate 74, the clamping seat 77 is fixedly assembled on the top of the corresponding plate insert plate 74. At this time, the top corner of the metal plate 9 is inserted into the clamping seat 77, which can lock and fix the metal plate 9. This can prevent it from shaking during grinding and improve the stability of the metal plate 9 during grinding.

[0041] After the metal plate 9 is fixed, the motor mounting bracket 8 is pushed horizontally and moved to one side of the metal plate 9. The worker observes the weld scar position on the surface of the metal plate 9 through the tempered glass 821. When the tempered glass 821 is aligned with the weld scar, the grinding disc is positioned on one side of the weld scar. The worker holds the handrail on the L-shaped frame plate 82 and pushes the L-shaped frame plate 82 to one side of the metal plate 9 to ensure that the grinding disc can contact the weld scar. During this process, the first motor 2 drives the grinding disc to rotate, which can perform local grinding on the weld scar. The second motor 5 drives the reciprocating screw 51 to rotate, which in turn drives the plate positioning bracket 7 to move up and down, which facilitates the adjustment of the vertical position of the metal plate 9 and ensures that the entire weld scar can contact the grinding disc, making it convenient to complete the comprehensive grinding of the weld scar. During the grinding process, the worker stands on one side of the L-shaped frame plate 82. The L-shaped frame plate 82 can shield the worker from the flying debris during grinding, reducing the chance of debris coming into contact with the worker's body and effectively improving the safety factor of the grinding operation.

[0042] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
