Description

Technical Field

[0001] The present application relates to the technical field of metal plate surface grinding, and in particular to an auxiliary device for grinding surface defects of metal plates. Background Art

[0002] During the manufacturing process, metal sheets will inevitably have defects on their surfaces, such as bumps, pits, and welds, which will cause the surface of the sheet to be uneven. Therefore, it is usually necessary to repair the surface defects after the sheet is formed. Depending on the type of surface defect, common grinding and repair methods include surfacing (repair welding) processes, which can fill the pit defects on the surface of the sheet. Grinding and repair is to use tools such as sandpaper and wire brushes to remove bumps, dirt, grease, and rust on the surface of metal sheets. Thermal spraying, brush plating, and immersion repair are all methods to improve the surface quality of the sheet, such as wear resistance and corrosion resistance.

[0003] At present, when repairing the bulge on the plate surface, due to the high strength of the metal plate, in order to achieve fast and efficient grinding operation, as shown in the attached manual Figure 1 As shown in the figure, usually the protrusions on the plate surface are ground by hand with a grinder. During the long-term continuous grinding operation, the operator not only has to support the weight of the entire grinder, but also has to move it, adjust and maintain the grinding depth, which puts a heavy physical burden on the operator. In addition, the influence of human factors can also cause the grinding depth to be insufficient or too deep. When the grinding depth is too deep ( Figure 2 As shown in the figure, the thickness of the plate body is difficult to recover, which will make the plate become waste and increase production costs. Summary of the invention

[0004] In response to the above-mentioned problems, the present application aims to provide an auxiliary device for grinding surface defects of metal plates, which is equipped with a handheld grinder through a support frame to solve the current problem of excessive physical burden caused by long-term manual holding in the air, and the depth of the grinding head of the handheld grinder and the position on the surface of the plate can be adjusted through an adjustment structure, thereby completely and accurately realizing the grinding operation of the surface defects of the plate.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted in this application is as follows: an auxiliary device for grinding surface defects of metal plates, the defects are ground using a handheld grinder, characterized in that: the auxiliary device is a support frame that can be positioned on the surface of the plate, the handheld grinder is detachably assembled on the support frame, and an adjustment structure for adjusting the grinding position of the handheld grinder in space is provided on the support frame.

[0006] Preferably, the adjustment structure includes a support frame having a horizontal sliding rod suspended on a plate, a sliding sleeve is sleeved on the horizontal sliding rod, and the handheld grinder is vertically hinged on the sliding sleeve.

[0007] Preferably, the support frame further comprises symmetrically arranged horizontal longitudinal bars, and both ends of the horizontal sliding bar are slidably connected to the horizontal longitudinal bars.

[0008] Preferably, a lockable hinge screw is provided at the hinge between the handheld grinder and the sliding sleeve.

[0009] The beneficial effect of the present application is that the auxiliary device can be fastened to any position on the surface of the plate through the support frame. During the grinding process of assembling the handheld grinder, the problem of displacement of the support frame caused by the contact between the handheld grinder and the plate surface can be resisted, thereby ensuring the accuracy of the grinding operation.

[0010] At the same time, the handheld grinder is assembled through the support frame to solve the problem of excessive physical burden caused by long-term manual holding in the air, and the depth of the grinding head of the handheld grinder and the position on the surface of the plate can be adjusted by adjusting the structure, so as to completely and accurately realize the grinding operation of the surface defects of the plate.

[0018] In order to enable ordinary technicians in the field to better understand the technical solution of the present application, the technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.

[0019] See attached Figures 1 to 6The auxiliary device for grinding the surface defects of metal plates is shown in the figure. The defect grinding uses a handheld grinding machine 1. Currently, the handheld grinding machine 1 is manually held to perform the plate surface defect grinding operation. Figure 1 In order to solve the problem of excessive physical burden caused by long-term manual grinding and the problem of excessive grinding affecting the yield of the plate, the present application is designed with auxiliary devices, such as Figure 5 As shown, it is a support frame 2 that can be positioned and placed on the surface of the plate, and preferably a vacuum suction cup 4 is provided at the bottom end of the vertical support rod of the support frame 2, which can fasten the support frame 2 to any position on the surface of the plate to achieve the positioning of the support frame 2. In the grinding process described later, the problem of displacement of the support frame 2 caused by the contact between the handheld grinder 1 and the surface of the plate can be resisted, thereby ensuring the accuracy of the grinding operation.

[0020] In order to solve the problem of excessive physical burden caused by holding the handheld grinding machine 1 in the air for a long time, Figure 3 As shown, the hand-held grinder 1 is detachably mounted on the support frame 2, and an adjustment structure for adjusting the grinding position of the hand-held grinder 1 in space is provided on the support frame 2. The depth of the grinding head of the hand-held grinder 1 and the position on the surface of the plate can be adjusted through the adjustment structure, so as to completely and accurately realize the grinding operation of the surface defects of the plate.

[0021] Specifically, Figure 3-4 As shown, the adjustment structure includes a support frame 2 having a horizontal slide bar 21 suspended on the plate, a slide sleeve 22 is sleeved on the horizontal slide bar 21, and the hand-held grinder 1 is vertically hinged on the slide sleeve 22. Through the hinge structure, the hand-held grinder 1 is driven to rotate vertically to adjust the grinding depth of its grinding head on the plate surface; and through the sliding of the slide sleeve 22 on the horizontal slide bar 21, the grinding position of the grinding head can be adjusted horizontally and horizontally, so that the defects can be completely polished horizontally and horizontally.

[0022] At the same time, in order to achieve complete grinding of defects in the longitudinal direction, such as Figure 6 As shown, the support frame 2 further includes a symmetrically arranged horizontal longitudinal rod 23, and both ends of the horizontal slide bar 21 are slidably connected to the horizontal longitudinal rod 23. The horizontal slide bar 21 is driven to slide on the horizontal longitudinal rod 23, so that the defect can be completely polished in the longitudinal direction, thereby combining the above-mentioned horizontal, lateral and depth controllable adjustment method to achieve a fast, labor-saving and accurate grinding operation of the surface defects of the plate.

[0023] In order to maintain the consistency of the grinding depth and avoid deepening the grinding depth due to the random rotation of the handheld grinding machine 1, Figure 3As shown, a lockable hinge screw 3 is provided at the hinge of the hand-held grinder 1 and the sleeve 22. During operation, the hand-held grinder 1 is slid to the outside of the defect to be grinded, and is driven to rotate, so that its grinding head is against the non-defective part of the plate surface (the grinding depth is positioned with the reference surface), and then the grinding head is locked by rotating the hinge screw 3, and then the hand-held grinder 1 is driven to slide horizontally and vertically, so that the defect position can be accurately and completely grinded.

[0024] The principle of the present application is: during operation, the support frame 2 is placed at the defect position on the plate surface, and the support frame 2 is fastened to the plate surface by a vacuum suction cup to achieve the positioning of the support frame 2. Then the handheld grinder 1 is slid to the outside of the defect to be polished, and it is driven to rotate, so that its grinding head is against the non-defective part of the plate surface (the grinding depth is positioned with the reference surface), and then the grinding head is locked by rotating the articulated screw 3, and then the handheld grinder 1 is driven to slide horizontally and vertically, so that the defect position can be accurately and completely polished.

[0025] The above shows and describes the basic principles, main features and advantages of the present application. Without departing from the spirit and scope of the present application, the present application may have various changes and improvements, which fall within the scope of the present application to be protected.
