Description

Furthermore, with the continuous development of shipbuilding technology, the curved surface designs of ship plates are becoming increasingly diverse, placing higher demands on the adjustment and fixing capabilities of plate grinding equipment. Traditional plate grinding equipment can no longer meet the needs of modern shipbuilding, urgently requiring a grinding device capable of flexibly adjusting and fixing ship plates with different curvatures.

[0027] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0028] See Figures 1-3 As shown, a plate grinding device for shipbuilding includes a base 1, an adjusting support mechanism 2, and a grinding mechanism 3. The adjusting support mechanism 2 is disposed on the top of the base 1 and includes a guide frame 21, a limiting part 22, a displacement part 23, and a rotating abutment roller 24. The guide frame 21 is a pair and is disposed on the top of the base 1. The limiting part 22 is a pair and is disposed on the top of the guide frame 21, and a stroke groove is provided on both sides of the limiting part 22. The displacement part 23 is a pair and is slidably disposed on the side of the limiting part 22. The rotating abutment roller 24 is a pair and is rotatably disposed on the side of the displacement part 23, and the rotating abutment roller 24 is used to support the ship plate to be processed. The grinding mechanism 3 is disposed on the top of the base 1.

[0029] When it is necessary to grind the ship plates to be processed, the worker first places the ship plates to be processed on top of the rotating abutment rollers 24 using a robot or lifting tool. Then, the displacement part 23 can rise and move away from each other along the clearance fit restriction part 22. By the rising and moving away from each other of the two rotating abutment rollers 24, the ship plates to be processed with different curvatures can be supported and abutted, thus improving applicability.

[0030] See Figures 2-4 As shown, the adjusting support mechanism 2 also includes a first hydraulic cylinder 25, an ejector rod 26, and a support plate 27; the first hydraulic cylinder 25 has a pair and is respectively disposed on the top of the guide frame 21, and the first hydraulic cylinder 25 is located on the side of the limiting part 22; the ejector rod 26 is disposed at the output end of the first hydraulic cylinder 25; the support plate 27 is disposed on the top of the ejector rod 26, and the support plate 27 is located below the rotating abutment roller 24.

[0031] When the displacement part 23 needs to slide relatively away from the limiting part 22, the first hydraulic cylinder 25 is activated and drives the ejector rod 26 and the support plate 27 to rise. During this process, the support plate 27 can lift the rotating abutment roller 24, and the rotating abutment roller 24 can rotate when it is lifted, which can reduce the contact friction with the support plate 27.

[0032] See Figures 2-4 As shown, the adjusting support mechanism 2 also includes a connecting plate 28, a first telescopic cylinder 29, and an abutment plate 291; the connecting plate 28 has a pair and is respectively disposed on both sides of the support plate 27; the first telescopic cylinder 29 has a pair and is respectively disposed on the side of the connecting plate 28; the abutment plate 291 is disposed at the output end of the first telescopic cylinder 29.

[0033] After the ship plate to be processed is lifted by the rotating abutment roller 24, the first telescopic cylinder 29 is activated and drives the abutment plate 291 to move until the abutment plate 291 clamps both sides of the ship plate to be processed. This prevents the ship plate to be processed from shifting during the subsequent grinding process.

[0034] See Figure 5 and Figure 6 As shown, the grinding mechanism 3 includes a frame 31, a first linear driver 32, and a moving block 33; the frame 31 is disposed on the top of the base 1; the first linear driver 32 is disposed on the top of the frame 31; the moving block 33 is slidably disposed on the top of the frame 31, and the moving block 33 is connected to the output end of the first linear driver 32.

[0035] The output end of the first linear actuator 32 is equipped with a screw for driving the moving block 33 to move. When the first linear actuator 32 is started, it can drive the screw to rotate. When the screw rotates, it can drive the moving block 33 to move.

[0036] See Figure 6 and Figure 7 As shown, the grinding mechanism 3 also includes a second linear actuator 34, a sliding block 35, and a second telescopic cylinder 36; the second linear actuator 34 is disposed at the bottom of the moving block 33; the sliding block 35 is slidably disposed at the bottom of the moving block 33, and the sliding block 35 is connected to the output end of the second linear actuator 34; the second telescopic cylinder 36 is disposed at the bottom of the sliding block 35.

[0037] When the moving block 33 moves, it can drive the second linear actuator 34 to move. The output end of the second linear actuator 34 is provided with a lead screw for driving the sliding block 35 to move. When the lead screw rotates, it can drive the sliding block 35 and the second telescopic cylinder 36 to move.

[0038] See Figure 6 and Figure 7As shown, the grinding mechanism 3 also includes a connecting block 37, a rotary driver 38, and a grinding roller 39; the connecting block 37 is located at the output end of the second telescopic cylinder 36; the rotary driver 38 is located beside the connecting block 37; and the grinding roller 39 is located at the output end of the rotary driver 38.

[0039] When grinding is required on the ship plates to be processed, the sliding block 35 moves, causing the connecting block 37 to move. When the moving block 33 moves, it simultaneously moves both the sliding block 35 and the connecting block 37. When the height of the grinding roller 39 needs adjustment, the second telescopic cylinder 36 is activated, causing the connecting block 37 and the grinding roller 39 to move synchronously. The rotary driver 38 is activated, causing the grinding roller 39 to rotate. This allows for adjustment of the position of the grinding roller 39, enabling grinding of ship plates with different curved surfaces.

[0040] See Figure 6 and Figure 7 As shown, the polishing mechanism 3 also includes a positioning plate 391 and a dust collection device 392; the positioning plate 391 is disposed on the side of the connecting block 37; the dust collection device 392 is disposed on the top of the positioning plate 391 and is located on the side of the polishing roller 39.

[0041] To reduce the waste generated during the polishing process, the connecting block 37 moves, which drives the positioning plate 391 and the dust collection device 392 to move synchronously. When the dust collection device 392 is activated, it can collect the waste generated during the polishing process.

[0042] See Figure 6 and Figure 7 As shown, the rotating abutment roller 24 is made of rubber.

[0043] The rotating contact roller 24 is preferably made of rubber, which can increase the contact friction with the ship plate to be processed.

[0044] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
