Description

Technical Field

[0001] The present application relates to the technical field of titanium plate surface defect grinding, and in particular to a titanium plate surface defect auxiliary grinding device. Background Art

[0002] Titanium plates have many unique properties, so they are widely used in many fields, mainly including the aerospace field. Titanium plates are used to manufacture key components such as fuselages and engine parts in the aerospace field due to their high strength, low density and good corrosion resistance; in the medical field, titanium plates are used in dental and orthopedic surgeries, such as titanium alloy tooth implants and artificial joints, because they are non-toxic, non-magnetic and corrosion-resistant to the human body; in the chemical field, titanium plates are often used to manufacture chemical equipment, reactors and pipelines to withstand harsh environments such as strong acids and alkalis. It also includes fields such as shipbuilding and marine engineering.

[0003] The current processing technology of titanium plate includes melting raw materials such as sponge titanium into ingots, then high-temperature forging the ingots to form titanium plate blanks, and surface treatment to form titanium plate finished products. During the heat treatment and mechanical processing of metal plates, due to internal structural defects, cracks, pits and other defects (such as Figure 1 As shown), in the process of plate surface treatment, surface defects need to be treated, and the treatment method is usually grinding. Especially for cracks, repair welding is performed after grinding, and grinding is performed again to eliminate the crack defects.

[0004] At present, when dealing with surface defects (especially cracks) of plates, operators usually use handheld grinders to grind the cracks. This operation is highly flexible, but metal plates are usually made of hard materials, and it takes a long time to grind the cracks. During the grinding process, the operator continues to hold the grinder and constantly adjusts it according to the depth and direction of the cracks. There is a heavy physical burden on manual grinding. For continuous production of plates and when there are many surface defects, the physical burden of this operation is further increased, which will further lead to excessive grinding depth and over-grinding (such as Figure 4 As shown in the figure, it is not conducive to accurate grinding and improving grinding efficiency. In addition, during the hand-held grinding process, the grinding head of the hand-held grinder rotates at high speed, and there is a reaction force after contacting the cracks on the surface of the plate. When the operator grinds for a long time, the impact of this reaction force will pose a safety hazard. Summary of the invention

[0005] In response to the above-mentioned problems, the present application aims to provide a titanium plate surface defect auxiliary grinding device, which can solve the physical burden of long-term manual support during the defect grinding process, so that the operator can accurately control the handheld grinder according to the crack depth and direction, thereby improving the grinding quality and efficiency.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted in this application is as follows: a titanium plate surface defect auxiliary grinding device, including a hand-held grinder, characterized in that: the hand-held grinder is equipped with an assembly mechanism for supporting it on the plate, and an adjustment structure for driving the hand-held grinder to contact the surface of the plate is also arranged between the assembly mechanism and the hand-held grinder.

[0007] Preferably, the assembly mechanism comprises an assembly plate, on which a clamp for connecting and fixing the handheld grinder is arranged, and support rods for suspending and supporting the handheld grinder are evenly arranged at the bottom of the assembly plate.

[0008] Preferably, the adjustment structure is to hinge the clamp to the assembly plate, and the hinge is adjustable and lockable.

[0009] Preferably, each of the support rods is hinged on the mounting plate, and a tension spring is provided between the support rod and the mounting plate, and a wheel body in contact with the surface of the plate is provided at the end of each support rod.

[0010] The beneficial effect of the present application is that the auxiliary grinding device can assemble the handheld grinder and suspend it on the surface of the plate through an assembly mechanism, thereby solving the physical burden of long-term manual support during the defect grinding process. The operator can then accurately control the handheld grinder according to the crack depth and direction, thereby improving the grinding quality and efficiency.

[0011] The adjustment structure can flexibly adjust the grinding state of the grinding head of the handheld grinder in the suspended state, and is suitable for adjustment according to the crack state to achieve flexible grinding operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] 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.

[0021] Refer to the attached Figures 1 to 7 The titanium plate surface defect auxiliary grinding device shown in FIG. 1 includes a hand-held grinder 1. Figure 2 As shown, the handheld grinder is manually held to perform the grinding operation on the surface defects of the plate. In order to solve the excessive physical burden of long-term manual grinding with a handheld grinder, and other grinding quality and operation safety issues caused by it, the present application assembles an assembly mechanism on the handheld grinder 1 to support it on the plate. Through the assembly mechanism, the handheld grinder 1 can be assembled and suspended on the surface of the plate. In the process of grinding defects, the physical burden of long-term manual support is solved, and then the operator can accurately control the handheld grinder 1 according to the depth and direction of the crack, thereby improving the grinding quality and grinding efficiency.

[0022] In order to achieve the adaptive adjustment of the suspended hand-held grinder 1 according to the depth of the crack, an adjustment structure for driving the hand-held grinder 1 to contact the surface of the plate is also provided between the assembly mechanism and the hand-held grinder 1. The adjustment structure can flexibly adjust the grinding state of the grinding head of the hand-held grinder 1 in the suspended state, which is suitable for adjustment according to the crack state.

[0023] Specifically, Figure 5-7 As shown, the assembly mechanism includes an assembly plate 2, on which a clamp 3 is arranged to connect and fix the hand-held grinder 1. The clamp 3 is preferably a snap-on structure. After the hand-held grinder 1 is placed on the clamp 3, it can be quickly fixed and assembled with the assembly plate 2 through the snap-on structure. At the same time, after the grinding operation is completed, the hand-held grinder 1 can be quickly disassembled.

[0024] like Figure 5 , 7 As shown, support rods 4 for suspending and supporting the hand-held grinder 1 are evenly arranged at the bottom of the assembly plate 2. The plurality of support rods 4 are in contact with the surface of the plate, so that the assembly plate 2 and the hand-held grinder 1 are suspended and supported on the surface of the plate, and the burden of manual long-term holding is solved during the grinding process.

[0025] like Figure 7As shown, the adjustment structure is to hinge the clamp 3 with the assembly plate 2. After the suspension assembly of the handheld grinder 1 is realized as described above, the upper and lower positions of the grinding head can be adjusted by driving it to hinge and rotate relative to the assembly plate 2, thereby adjusting the grinding depth of the grinding head on the crack.

[0026] When grinding horizontally along the surface of the plate, in order to avoid the up and down deviation of the grinding head, the above-mentioned hinge can be adjusted and locked, specifically by creating an articulated screw (not shown in the figure). When the grinding depth of the grinding head is adjusted, it can be locked through the articulated screw to limit the grinding depth of the grinding head. After that, the handheld grinder 1 can be moved to perform horizontal grinding operations on the surface of the plate.

[0027] Usually the depth of the crack along its length is not consistent. In order to solve the problem of the position adjustment of the grinding head by the above-mentioned articulated screw, as Figure 5 , 7 As shown, each of the support rods 4 is hinged on the assembly plate 2, and a tension spring 5 is arranged between the support rod 4 and the assembly plate 2. The tension spring 5 selects an appropriate elastic coefficient according to the weight of the hand-held grinder 1 to ensure that after the hand-held grinder 1 is assembled, the grinding head is close to the surface of the plate in a stable state. When grinding, the operator applies downward pressure when supporting the hand-held grinder 1 to overcome the force of the tension spring 5, so that each support rod 4 is Figure 7 The middle arc arrow direction is deflected, thereby lowering the height of the handheld grinder 1 as a whole, achieving flexible adjustment of the grinding depth of the grinding head, and improving the convenience of grinding operations according to different crack depths.

[0028] The direction of the crack is usually irregular. In order to flexibly adjust the working position of the hand-held grinder 1 according to the direction of the crack, Figure 7 As shown, a wheel body 6 in contact with the surface of the plate is provided at the end of each support rod 4. The wheel body 6 is preferably a universal wheel structure. The operator can support the handheld grinder 1 and drive it to move flexibly on the surface of the plate to achieve precise grinding according to the direction of the crack.

[0029] The principle of the present application is: when performing the surface defect grinding operation of the plate, firstly place the assembly plate 2 on the surface of the plate through the wheel body 6, then place the hand-held grinder 1 on the clamp 3 and clamp it in an annular direction, that is, realize the rapid suspension assembly of the hand-held grinder 1. Then, according to driving the wheel body 6 to roll, move the grinding head to one end of the crack, then rotate and adjust the hand-held grinder 1 so that the grinding head contacts the crack, and can be selectively locked by the hinge screw, then apply downward pressure to the hand-held grinder 1 to overcome the force of the tension spring 5, so that the grinding head moves down during the grinding process, and the crack depth is completely ground. At the same time, the hand-held grinder 1 is driven by the wheel body 6 to move along the direction of the crack, so that the continuous grinding operation of the crack can be realized.

[0030] 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.
