Description

Technical Field

[0001] The present application relates to the technical field of welding devices, and in particular to a high-precision grinding plate welding device. Background Art

[0002] Diamond water grinding discs are mainly used for floor renovation and stone processing operations. They are mainly made of a grinding disc and a grinding block welded together, and the grinding block contains highly wear-resistant diamond particles.

[0003] Traditional grinding wheel welding devices usually adopt a fixed clamping method, and the welding tool is fixed in position. Due to the large differences in grinding wheel sizes, the fixed welding tool is often limited by the spatial angle during welding, and it is impossible to achieve precise welding of key points on the grinding wheel, resulting in uneven welding quality, which in turn affects the connection strength between the grinding block and the grinding disc, and increases the risk of the grinding block falling off during use. Utility Model Content

[0004] The problem to be solved by this application is that the existing grinding plate welding device usually adopts a fixed clamping method, and the welding tool is fixed in position, which is easily restricted by the spatial angle and cannot accurately weld the key points on the grinding plate, making the grinding block prone to falling off during use.

[0005] In order to solve the above technical problems, the present application provides a high-precision grinding plate welding device, including a base for serving as a basic support, a welding assembly capable of spatial rotation is arranged on the upper part of the base, and a supporting assembly for clamping and fixing the grinding plate and capable of horizontal rotation and front and back flipping is arranged on one side of the base. The welding assembly and the supporting assembly can be adjusted through spatial angle operation to perform precise welding operations on the key points of the grinding plate.

[0006] Since the welding device of the present application is designed with a welding assembly and a supporting assembly, the welding assembly and the supporting assembly can realize full welding operation of key points of the grinding plate with adjustable spatial angle, which solves the problem that the grinding plate welding device in the prior art usually adopts a fixed clamping method and the welding tool is fixed in position, which is easily restricted by the spatial angle and cannot accurately weld the key points on the grinding plate, making the grinding block easy to fall off during use.

[0015] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application. Example

[0016] This application relates to a high-precision grinding disc welding device, such as Figure 1-7 As shown, the welding device includes a base 2 for serving as a basic support, a welding assembly 1 capable of spatial rotation is arranged on the upper part of the base 2, and a supporting assembly 3 for clamping and fixing the grinding plate and capable of horizontal rotation and front and back flipping is arranged on one side of the base 2. Therefore, with the help of the coordinated operation of the welding assembly 1 and the supporting assembly 3, the spatial angle limitation encountered by the grinding plate during the welding process can be effectively avoided, so that the welding assembly 1 and the supporting assembly 3 can be adjusted through spatial angle operation to perform precise welding operations on the key points of the grinding plate.

[0017] The welding assembly 1 includes a column 6, a robotic arm, and a welding tool. The column 6 is arranged on the upper part of the base 2 and is arranged in a vertical state. A robotic arm extending outward and capable of rotating around it is arranged on one side of the top of the column 6, and a welding tool for performing welding operations (not shown in the figure) is arranged at the end of the robotic arm. In order to enable the robotic arm to achieve spatial angle rotation operation, the robotic arm is divided into a three-section arm body 5 structure, and a first motor 4 for rotational driving is arranged between each section of the arm body 5. In order to achieve effective control of the rotation angle of the arm body 5, the first motor 4 is preferably a stepper motor or a servo motor, so that multiple first motors 4 are used to drive the three-section arm body 5 to perform coordinated rotation operations in space, so that the welding tool at the end of the robotic arm can perform welding operations between the grinding block and the grinding disc.

[0018] The supporting assembly 3 includes a bracket 13, a rotating part, and a flipping part. The bracket 13 is arranged on one side of the base 2. A rotating part connected to the bracket 13 through a bearing seat is arranged on the upper part of the bracket 13 and can drive the grinding plate to rotate horizontally. In order to assist the welding assembly 1 in performing spatial angle adaptation and adjustment operations, a flipping part that can drive the rotating part to flip forward and backward is also provided on the upper part of the bracket 13.

[0019] The rotating part includes a second motor 16, a gear plate 15, and a frame 11. The frame 11 is arranged on the upper part of the bracket 13 and connected to it through a bearing seat. A gear plate 15 connected to it and capable of rotating synchronously is also arranged on one side of the frame 11. A second motor 16 is arranged inside the bracket 13 to drive the gear plate 15 to rotate through a gear shaft. The gear plate 15 is driven to rotate by the second motor 16, and the gear plate 15 drives the frame 11 to flip forward and backward around the bracket 13.

[0020] The flip part includes a third motor 14, a ring gear 12, and a disk body 10. The disk body 10 is arranged on the upper part of the frame body 11 and connected to it through a bearing seat. The lower part of the disk body 10 is arranged with a ring gear 12 concentrically connected to it, and the inside of the frame body 11 is arranged with a third motor 14 that drives the ring gear 12 to rotate through a gear shaft. The ring gear 12 is driven to rotate by the third motor 14, and the ring gear 12 drives the disk body 10 to perform a circumferential horizontal rotation operation around the frame body 11.

[0021] In order to improve the welding efficiency of the grinding wheel, a plurality of supporting components 3 arranged side by side and at intervals can be added to one side of the base 2, and the welding component 1 can be one group or multiple groups. When the number is multiple groups, they are arranged corresponding to the supporting components 3 and cannot be moved. When the number is one, it is necessary to add a driving component inside the base 2 that can drive the welding component 1 to move horizontally back and forth.

[0022] The driving assembly includes a slide rail 8, a slider 7, a rack 9, and a fourth motor. The slide rails 8 are symmetrically arranged on both sides of the length direction inside the base 2. The sliders 7 slidably connected to the slide rails 8 are symmetrically arranged at the bottom of the column 6, and a rack 9 for guiding walking is also arranged inside the base 2. A fourth motor (not shown in the figure) is arranged on the upper part of the column 6 and is engaged with the rack 9 through a gear shaft. The gear shaft is driven by the fourth motor to engage and roll along the surface of the rack 9, and then the column 6 can be driven to slide along the surface of the slide rail 8 with the help of the slider 7.

[0023] During use, the grinding disc is placed in the center of the upper part of the disc body 10, and then the disc body 10 can be clamped and fixed by the clamping claws that can slide along the surface of the disc body 10, and then the grinding block to be welded is placed on the upper part of the disc body 10. At this time, the disc body 10 remains horizontal, and then the first motor 4 is used to mobilize the arm body 5 to control the movement of the robotic arm in the space to perform a preliminary welding operation on the grinding disc and the grinding block. Then, the second motor 16 can be used to drive the gear disc 15 to drive the frame 11 to flip to perform a full repair welding operation on the key points between the grinding disc and the grinding block. The third motor 14 then drives the ring gear 12 to rotate and drive the disc body 10 to rotate, thereby changing the position of the grinding block required for the welding operation, so that sufficient key key welding operation can be achieved between the grinding disc and the grinding block, avoiding the situation where the welding amount is limited due to the limitation of the spatial angle and the welding strength is insufficient. The fourth motor can also be used to drive the gear shaft to roll along the rack 9, so that the welding assembly 1 can reciprocate along the surface of the base 2, so that the grinding discs on the upper parts of multiple supporting assemblies 3 can be welded.
