Description

Technical Field

[0001] This utility model relates to the field of welding and grinding technology, specifically to a weld grinding treatment device. Background Technology

[0002] Weld grinding equipment is typically used to remove unevenness, welding spatter, oxide layer and welding marks on the weld surface generated during the welding process, in order to improve the appearance quality and structural strength of the welded joint.

[0003] The existing patent with publication number CN208880369U proposes a handheld weld grinding device. The grinding frame and the operating rod of the device are elastically connected, which achieves good tensile, impact and bending strength. It can effectively reduce the impact damage to the workpiece surface caused by the impact force and vibration generated when the grinding roller contacts the workpiece. It facilitates smooth grinding, higher grinding accuracy, improves grinding efficiency and quality, and extends the service life of the grinding equipment, while reducing the purchase and maintenance costs of grinding equipment.

[0004] However, when the device grinds the weld at the flat weld joint, it cannot guarantee that the weld will be flat after grinding, which may cause the operator's hand to tilt, resulting in a depression or tilted groove at the weld. Utility Model Content

[0005] The purpose of this utility model is to provide a weld grinding treatment device to solve the problem that existing devices cannot guarantee that the weld is in a flat state after grinding, which may cause the operator's hand to tilt, resulting in depressions or tilted grooves at the weld.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a weld grinding device, including a portable tube, a grinding motor fixedly mounted on the upper end of the portable tube, a grinding plate fixedly mounted on the output end of the grinding motor, an anti-tilting structure provided on the outer wall of the portable tube, the anti-tilting structure including a mounting frame fixedly mounted on the outer wall of the portable tube, four movable rods movably mounted inside the mounting frame, a cross plate fixedly mounted on the upper end of the four movable rods, a stabilizing member provided on the lower end of each of the four movable rods, and a spring fixedly mounted on the upper end of the stabilizing member located on the outer wall of the movable rod.

[0007] Preferably, the stabilizer has an internal adaptation structure, which includes a fixing rod fixedly disposed on the inner wall of the stabilizer, and a traveling cylinder fixedly disposed on the outer wall of the fixing rod.

[0008] Preferably, the lower end of the cross plate is welded to the upper end of the movable rod.

[0009] Preferably, the walking cylinder is made of steel.

[0010] Preferably, the output shaft of the grinding motor is fixedly provided with a connecting plate, the upper end of the grinding plate is fixedly provided with a mounting plate, and the upper end of the mounting plate is fixedly provided with a plurality of screws in a ring. The output end of the screws passes through the mounting plate and the outer wall is threaded with a nut.

[0011] Preferably, a handle is fixedly provided on the outer wall of the portable tube, and a groove is provided at the lower end of the handle.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1) By setting up an anti-tilting structure, when grinding the weld at the top of the flat plate, the vertical elastic stabilizer can prevent the operator from tilting their hand when grinding with a portable cylinder, which would cause uneven grinding and ensure the neatness of the weld after grinding.

[0014] 2) By setting up an adaptation structure, when grinding long welds, the operator can move the portable cylinder smoothly while ensuring that the walking cylinder is in contact with the flat object, thereby avoiding the portable cylinder tilting during grinding. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Combination Figures 1-4 A weld grinding device includes a portable tube 1, a grinding motor 3 fixedly mounted on the upper end of the portable tube 1, a grinding plate 4 fixedly mounted on the output end of the grinding motor 3, an anti-tilting structure 5 on the outer wall of the portable tube 1, the anti-tilting structure 5 including a mounting frame 6 fixedly mounted on the outer wall of the portable tube 1, four movable rods 8 movably mounted inside the mounting frame 6, a cross plate 7 fixedly mounted on the upper end of the four movable rods 8, a stabilizing member 9 on the lower end of each of the four movable rods 8, and a spring 10 fixedly mounted on the upper end of the stabilizing member 9 located on the outer wall of the movable rods 8.

[0023] See Figure 1 , Figure 3 and Figure 4 Furthermore, the lower end of the horizontal plate 7 is welded to the upper end of the movable rod 8, the walking cylinder 13 is made of steel, the output shaft of the grinding motor 3 is fixedly provided with a connecting plate 14, the upper end of the grinding plate 4 is fixedly provided with a mounting plate 15, the upper end of the mounting plate 15 is fixedly provided with a ring of multiple screws 16, the output end of the screws 16 passes through the mounting plate 15 and the outer wall is threaded with a nut 17, the outer wall of the portable cylinder 1 is fixedly provided with a handle 2, and the lower end of the handle 2 is provided with a groove.

[0024] Specifically, the steel walking cylinder 13 can ensure long-term use. The connecting plate 14, mounting plate 15, and nut 17 work together to fix the grinding plate 4 to the output end of the grinding motor 3.

[0025] Example 2

[0026] See Figure 3 Furthermore, based on Embodiment 1, the internal structure of the stabilizing member 9 is provided with an adapter structure 11, which includes a fixing rod 12 fixedly disposed on the inner wall of the stabilizing member 9, and a traveling cylinder 13 fixedly disposed on the outer wall of the fixing rod 12.

[0027] Specifically, when it is necessary to move the portable tube 1 smoothly, the fixing rod 12 facilitates the rotation of the walking tube 13 and reduces the friction between the walking tube 13 and the surface of the object.

[0028] In actual operation, when it is necessary to weld block-shaped welds, the lower end of the stabilizing member 9 is placed stably on the upper surface of the object. At this time, the lower end of the grinding plate 4 contacts the protruding weld and the grinding motor 3 is started, so that the grinding plate 4 grinds the protruding weld. During the grinding process, the lower ends of the four stabilizing members 9 do not separate from the upper surface of the object, ensuring that the portable tube 1 will not tilt when it is in operation.

[0029] When grinding long welds, hold the handle 2 and ensure that the lower ends of the four traveling cylinders 13 are in contact with the surface of the object, while moving the portable cylinder 1 smoothly so that the grinding plate 4 remains parallel when grinding the protruding weld.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
