[0027] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0028] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0030] The utility model provides a welding bead maintenance device, which can be used to repair the welding point between two welded objects so as to scrape off the welding slag at the welding point.

[0031] In one embodiment, see Figure 2 and Figure 3 The weld repair device includes a tool holder 1, a tool 2 and a protective member 3, wherein the tool holder 1 as a main body can provide an installation environment for the tool 2 and the protective member 3, and can also play a role in supporting the tool 2 and the protective member 3.

[0032] The tool 2 is connected to the tool holder 1. The tool 2 has a cutting structure. The cutting structure of the tool 2 is placed against the welding position where the welding slag needs to be scraped off. The tool holder 1 is driven to move to drive the tool 2 to move accordingly, and the welding slag can be scraped off using the cutting structure.

[0033] It is worth mentioning that the tool 2 can be integrally formed with the tool holder 1 or can be separately formed and then installed together. When the tool 2 and the tool holder 1 are integrally formed, they have better stability and can be formed at one time during production, saving production processes. When the tool 2 and the tool holder 1 are separately formed, the two can be formed separately and then installed together. This makes it easy to replace the type of tool 2 and can also facilitate repair and replacement when the tool 2 is worn.

[0034] The protective member 3 is connected to the knife holder 1, and the protective member 3 has a protective space 321. The structure of the knife 2 for cutting is located on the side of the protective member 3 facing away from the protective space 321. It should be noted that the protective space 321 can be one or more. When there is only one part to be protected, it is preferred to set a protective space 321 to cover the part to be protected. When there are two parts to be protected that are spaced apart and the position for removing welding slag is located between the two, it is preferred to set two protective spaces 321, one to cover one of the parts, and the other protective space 321 to cover the knife 2, that is, the protective space 321 is used to separate the knife 2 from the object. The number of protective spaces 321 that need to be set is determined according to actual conditions.

[0035] By providing the protective member 3, when the tool 2 is used to repair a welding position that requires cutting of welding slag, the protective member 3 can cover an object near the welding position within the protective space 321, so that the surface of the object and the tool 2 are separated by the protective member 3, thereby effectively preventing the tool 2 from accidentally scratching the surface of the object when cutting the welding slag, thereby ensuring the integrity of the object near the welding position to be repaired when the tool 2 is repairing the welding position.

[0036] In one embodiment, see Figure 2 and Figure 3 The protective member 3 includes a connecting plate 31 and a side plate 32 wound around the connecting plate 31 . The connecting plate 31 is connected to the blade holder 1 , and the side plate 32 is surrounded to form a protective space 321 .

[0037] Specifically, one side of the connecting plate 31 can be attached to the knife seat 1, and the connecting plate 31 can be connected to the knife seat 1 by screws, and the side plate 32 is arranged on the side of the connecting plate 31 facing away from the knife seat 1. The protective space 321 formed by the side plate 32 is an annular space, and the shape and size of the protective space 321 are not limited, as long as the object to be protected can be completely covered therein.

[0038] For example, please combine Figure 1 , Figure 1There are two parts that need to be welded when manufacturing power batteries. For the convenience of description, the two parts are defined as parts A and B, and the welding position between A and B that needs to be repaired is defined as C. When repairing the C position, the cutting part of the tool 2 needs to be abutted against the C position. At this time, the protective member 3 can be covered outside the part A, that is, the part A can be completely contained in the protective space 321. In this way, the protective member 3 can separate the part A and the tool 2, and the tool 2 is not easy to cut the part A when cutting the welding slag at the C position.

[0039] In addition, according to Figure 1 It can be seen that the outer surface of component A is roughly cylindrical, and the welding position C of component A and component B also extends along a circumference. Therefore, when the tool 2 in the present application abuts against the position C and needs to cut the welding slag, the tool 2 can be moved along the extension path of the position C by rotating the tool holder 1. At this time, the shape and size of the protective space 321 enclosed by the side plate 32 are preferably adapted to the outer size of component A.

[0040] In a specific embodiment, please refer to Figure 2 and Figure 3 The tool 2 includes a connecting end 21 and a maintenance end 22 connected together, the connecting end 21 is connected to the tool holder 1, and a cutting portion 221 is provided on the maintenance end 22, and the cutting portion 221 is located on the side of the side plate 32 facing away from the protection space 321. The connecting end 21 and the maintenance end 22 can be detachably connected by buckling, clamping or screw connection, or in a preferred solution, the connecting end 21 and the maintenance end 22 are integrally formed.

[0041] In the present application, the connection end 21 and the knife seat 1 are detachably connected, so that the tool 2 can be easily replaced or repaired. For example, the connection end 21 of the tool 2 can be connected to the knife seat 1 by snapping, buckling or bolting. Specifically, in the present embodiment, the knife seat 1 is provided with a first screw hole 122, and the connection end 21 is penetrated by a first through hole 211. A screw can be inserted into the first through hole 211, and the screw inserted into the first through hole 211 can be screwed into the first screw hole 122, so that the connection end 21 is connected to the knife seat 1.

[0042] It should be noted that in order to fix the tool 2 on the tool holder 1, the first through hole 211 is set as a stepped hole, and the smaller part of the stepped hole is set close to the first screw hole 122. The shape and size of the smaller part of the stepped hole are adapted to the screwed part of the screw, and the larger part of the stepped hole is adapted to the head of the screw. In this way, the screwed part of the screw can pass through the smaller part of the stepped hole and then be screwed in the first screw hole 122, while the head of the screw can only be located in the larger part of the stepped hole due to its larger size. In this way, the connecting end 21 can be clamped by the cooperation of the head of the screw and the tool holder 1.

[0043] It is worth mentioning that a gap is provided between the cutting portion 221 (i.e., the cutting structure of the cutter 2) and the side plate 32. By providing a gap between the cutting portion 221 and the side plate 32, a space for accommodating welding slag can be provided, thereby preventing the cut welding slag from continuously abutting against the cutting portion 221 due to lack of storage space, thereby affecting the life of the cutting edge of the cutting portion 221.

[0044] In addition, in the first direction (see Figure 2 , the direction shown by the Z axis in the figure is the first direction), and the end of the cutting portion 221 away from the connecting end 21 is not higher than the end of the side plate 32 away from the connecting plate 31 to avoid a large gap between the side plate 32 and the welding object.

[0045] In one embodiment, see Figure 2 and Figure 3 The tool holder 1 includes a first seat body 11 and a second seat body 12, which are connected together, preferably integrally formed, and the tool 2 and the protective member 3 are both connected to the second seat body 12. The first screw hole 122 is opened on the side wall of the second seat body 12, and the connecting plate 31 is connected to the end surface of the second seat body 12 facing away from the first seat body 11.

[0046] In a specific embodiment, the tool holder 1 further includes a driving member 13, which is connected to the tool holder 1. The user can hold the driving member 13 to drive the tool holder 1 to rotate, thereby driving the tool 2 on the tool holder 1 to move to cut the welding slag.

[0047] Specifically, the driving member 13 includes a gripping portion 131 and a connecting portion 132 connected together, the gripping portion 131 is for the user to hold, and the connecting portion 132 is detachably connected to the first seat body 11. The connecting portion 132 can be connected to the first seat body 11 by means of a snap connection, a buckle connection, or a screw connection. In the present application, the connecting portion 132 is preferably fixedly connected to the first seat body 11 by a screw.

[0048] In a more specific embodiment, a second screw hole 1322 is provided on the connecting portion 132, and the knife seat 1 is provided with a second through hole 121 which passes through the first seat body 11 and the second seat body 12, and a screw can be passed through the second through hole 121, and the screw passed through the second through hole 121 can be screwed into the second screw hole 1322, so that the connecting portion 132 is connected to the first seat body 11.

[0049] It should be noted that the setting method of the second through hole 121 here is consistent with the setting method of the first through hole 211 mentioned above, both of which are stepped holes, and the radial dimension of the second through hole 121 close to the first seat body 11 is smaller, so that the connecting part 132 can be fixedly connected to the first seat body 11 through the connection between the screw and the second screw hole 1322.

[0050] It is worth mentioning that, in order to ensure the stability of the connection between the connecting portion 132 and the first base body 11, so that the two are not easily moved relative to each other after being connected, a connecting groove 111 is further provided on the first base body 11, and the end of the connecting portion 132 away from the gripping portion 131 can be inserted into the connecting groove 111. In order to prevent the connecting groove 111 and the connecting portion 132 from rotating relative to each other, the connecting groove 111 is configured to have a polygonal cross-section, such as a triangle, a quadrilateral or a pentagon, and the cross-section of the end of the connecting portion 132 inserted into the connecting groove 111 is adapted to the cross-section of the connecting groove 111, so that the connecting groove 111 and the connecting portion 132 can be effectively prevented from rotating relative to each other.

[0051] Alternatively, in a preferred embodiment, the cross section of the connection groove 111 may also be circular, and the connection portion 132 has a limiting end 1321, and the cross-sectional shape and size of the limiting end 1321 are adapted to the connection groove 111, so that the limiting end 1321 can be inserted and adapted in the connection groove 111. The side wall of the connection groove 111 is provided with a limiting member 112 extending into the connection groove 111, and the side wall of the limiting end 1321 forms a limiting surface 13211. When the limiting end 1321 is inserted and adapted to the connection groove 111, the limiting member 112 can abut against the limiting surface 13211 to limit the relative rotation between the limiting end 1321 and the connection groove 111.

[0052] In one embodiment, see Figure 2 and Figure 3 The weld repair device is preferably provided with a plurality of cutters 2, and the plurality of cutters 2 are arranged on the cutter seat 1 at equal intervals around an axis. Specifically, in the present application, the cutter 2 is connected to the second seat body 12, and the second seat body 12 is preferably arranged in a cylindrical shape, and the cutter 2 is connected to the peripheral wall of the second seat body 12 around the central axis of the second seat body 12. These cutters 2 can be arranged at equal intervals, or two adjacent cutters 2 can be fitted together. It should be noted that the cutting portion 221 is arranged to protrude from the repair end 22, so that when the cutting portion 221 abuts against the welding position, the repair end 22 can have a certain gap with the welding position, so that the welding slag cut off by the cutting portion 221 has a storage space.

[0053] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent application. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
