DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] It should be noted that all directional indications in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0026] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] In addition, in the present utility model, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0028] In the related art, when a welding gun or other tool is used to weld the groove on a workpiece to be processed, the relative position between the welding gun and the groove of the workpiece to be processed is inaccurate, and the relative position includes the relative angle between the welding gun and the groove, which easily leads to poor quality of the weld formed at the final break. For example, the welding gun may collide with the welding gun during welding, which may affect the welding gun, or the weld may deviate, resulting in welding defects such as unfused or poor fusion between the welds. The welding angle is not stable enough, which may also lead to pores in the weld, affecting the efficiency and quality of the weld.

[0029] The embodiments of the present application provide a positioning component and a device to be processed, which can at least solve the above-mentioned technical problems to a certain extent.

[0030] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0031] Figure 1 A schematic diagram of the structure of a positioning component in some embodiments or certain embodiments of the present application is shown. Figure 2 A top view of a positioning assembly in some embodiments or certain embodiments of the present application is shown, with reference to Figure 1 and Figure 2 The embodiment of the present application provides a positioning assembly for positioning a welding gun 100 relative to a workpiece 10 to be processed. The workpiece 10 to be processed is provided with a groove 101. The groove 101 has a bottom surface 1011 and groove surfaces 1012 connected to both sides of the bottom surface 1011. One groove surface 1012 intersects with the bottom surface 1011 to form a first intersection line 1013. The positioning assembly includes:

[0032] A positioning member 1 is detachably arranged on a workpiece 10 to be processed, and the positioning member 1 is provided with a positioning portion 11 extending into the groove 101, and the positioning portion 11 is provided with a fitting surface 111 and a positioning plane 112, the fitting surface 111 is used for fitting and supporting on the groove surface 1012, the positioning plane 112 intersects with the fitting surface 111 to form a second intersection line 113, the second intersection line 113 extends along the first intersection line 1013 and is used to contact the first intersection line 1013, and the angle between the positioning plane 112 and the fitting surface 111 is the positioning angle α.

[0033] The workpiece 10 to be processed is provided with a groove 101, and the groove 101 has a bottom surface 1011 and groove surfaces 1012 connected to both sides of the bottom surface 1011, and the groove surface 1012 intersects with the bottom surface 1011 and forms a first intersection line 1013. Before welding the bottom surface 1011 of the groove 101, the positioning member 1 is set on the workpiece 10 to be processed, and the positioning member 1 and the workpiece 10 to be processed can be separated. The positioning portion 11 of the positioning member 1 extends to the groove 101, and the positioning portion 11 is supported by the groove surface 1012 of the groove 101 through the fitting surface 111, and cooperates with the positioning member 1 on the workpiece 10 to be processed as a whole, which can play a positioning and supporting role. The position of the positioning member 1 is fixed, and the positioning plane 112 of the positioning portion 11 intersects with the fitting surface 111 to form a second intersection line 113 extending along the first intersection line 1013. When the second intersection line 113 contacts the first intersection line 1013, the second intersection line 113 almost coincides with the first intersection line 1013. The positioning plane 112 extends from the first intersection line 1013 to the outside of the groove 101, and the angle between the groove surface 1012 and the bottom surface 1011 is divided into a positioning angle α between the positioning plane 112 and the fitting surface 111 (i.e., the groove surface 1012), and another angle between the positioning plane 112 and the bottom surface 1011. The positioning plane 112 can serve as a reference, and then the welding wire 1001 of the welding gun 100 is made to fit parallel to the positioning plane 112. The welding wire 1001 is fit parallel to the positioning plane 112, that is, the angle between the welding wire 1001 and the fitting surface 111 (that is, the groove surface 1012) is the angle of the positioning angle α. The angle and position of the welding wire 1001 of the welding gun 100 relative to the groove 101 can be determined more conveniently, ensuring stable welding of the welding gun 100, improving the quality of the weld obtained by welding at the groove 101, and solving the technical problem of the weld quality being affected to a certain extent.

[0034] Moreover, for robot welding or automated welding, the position of the welding gun 100 in the robot welding device or the automated welding device is corrected by the positioning component, so as to ensure the accuracy of the initial position of the welding gun 100 relative to the groove 101, fundamentally solving the problem of the incorrect angle of the welding gun 100 for non-first welding, and being able to ensure that the welding gun 100 is stable during the entire process of welding the groove 101, thereby reducing labor intensity and improving work efficiency; during the automated or robot welding process, each time the welding gun 100 forms a weld bead, it is offset by a fixed distance along the width direction of the groove 101 to weld the next weld bead, and the welding parameters do not fluctuate much during the overall welding process, the welding process is stable, the weld bead is beautifully formed, and there are no welding defects. During the process of gas shielded welding by robot or automatic welding, after the angle position of the welding gun 100 for the first welding is determined, the welding angle of the welding gun 100 is consistent from beginning to end in the same welding layer, and the gas protection is uniform, which avoids the problem of porosity defects caused by inadequate gas protection due to angle changes, keeps all welding positions and distances consistent, and avoids accidents of the welding gun 100 hitting the welded parts; saves the time for alignment and improves the working efficiency; reduces the problems of inconsistent angles due to repeated positioning; reduces the risk of hitting the welding gun 100 and extends the service life of the welding gun 100.

[0035] It should be noted that the positioning member 1 can be detachably provided on the workpiece 10 to be processed, which means that there is contact and interaction between the positioning member 1 and the workpiece 10 to be processed, such as abutment or support, etc., or it can be adsorption or tightening by fasteners.

[0036] In some embodiments, the positioning member 1 also includes a supporting portion 12 connected to the positioning portion 11, and the supporting portion 12 is supported on the workpiece 10 to be processed. Along the height direction A of the groove 101, the height of the positioning portion 11 is greater than the height of the groove 101 and less than the height of the supporting portion 12.

[0037] The support portion 12 of the positioning member 1 is connected to the positioning portion 11 and supported on the workpiece 10 to be processed, which is convenient for fixing and positioning the positioning member 1 as a whole. Along the height direction A of the groove 101, the height of the positioning portion 11 is greater than the height of the groove 101, which can effectively support and position the welding wire 1001 of the welding gun 100, and improve the accuracy of the welding of the welding gun 100. The height of the positioning portion 11 is less than the height of the support portion 12, which can reduce the overall volume of the positioning member 1. The space formed by the height difference between the positioning portion 11 and the support portion 12 can also facilitate the adjustment of the state of the welding wire 1001, which is conducive to improving the quality of the weld.

[0038] For ease of understanding, the length, width and height of the groove 101 are described here. Taking the bottom surface 1011 as a reference, the height of the groove 101 can be the height of the top of the groove 101 relative to the bottom surface 1011. The width of the groove 101 is the width between the two groove surfaces 1012, and the length of the groove 101 is the direction in which the groove 101 itself extends.

[0039] In some embodiments, depending on the groove 101 , the positioning angle α may be an acute angle or an obtuse angle.

[0040] In some embodiments, the height of the groove 101 may also be the height of the top of the groove 101 relative to the horizontal reference plane when the workpiece 10 to be processed needs to be welded, and the present application does not impose any limitation on this.

[0041] In some embodiments, the support portion 12 transitions to the positioning portion 11 via a step 14. The step 14 provides a relatively large space, which can be used to avoid and adjust the welding wire 1001.

[0042] In some embodiments, the positioning portion 11 may be a prism extending axially along the length direction of the groove 101, the positioning portion 11 may be a triangular prism, the two intersecting side surfaces of the positioning portion 11 are respectively configured as the fitting surface 111 and the positioning plane 112, the support portion 12 may be a cubic structure extending in the length direction along the width direction of the groove 101, and one end surface of the support portion 12 is connected to the surface of the positioning portion 11 other than the fitting surface 111 and the positioning plane 112. This facilitates processing and preparation.

[0043] In some embodiments, the support portion 12 and the positioning portion 11 may be integrally formed or detachably connected. In addition to the step 14, the support portion 12 and the positioning portion 11 having a height difference may also be transitioned by setting an arc. When the positioning portion 11 is a triangular prism, one edge of the prism may be configured as the second intersection line 113. This facilitates processing and preparation.

[0044] In some embodiments, along the length direction B of the groove 101, the thickness of the support portion 12 may be the same as the axial length of the positioning member 1, and the thickness of the support portion 12 may be 10 mm, along the width direction C of the groove 101, the length of the positioning member 1 may be 80 mm, and along the height direction A of the groove 101, the height of the positioning member 1 may be 20 mm. This is convenient for preparation and has good versatility.

[0045] It should be noted that Figure 1 and Figure 2 The dimensions indicated in the table omit the units. Figure 1 and Figure 2 The size data indicated in the figure is only a feasible sight line method of the present application. The structure and specific size of the positioning member can be adjusted according to the requirements, and the present application does not impose any restrictions on this. Figure 1 and Figure 2 The contents in square brackets are overlapping faces, lines, or faces and lines in the viewing direction.

[0046] In some embodiments, at least two positioning members 1 are disposed at intervals on the workpiece 10 to be processed, and the positioning angles α corresponding to two adjacent positioning members 1 are different.

[0047] The positioning assembly includes at least two positioning members 1 with different positioning angles α, which can be applied to welding processes in which different welding layers require different welding angles during welding, and can also meet the requirements of different angles of different grooves 101, thereby improving the versatility of the positioning assembly. For example, for processes such as flat welding with a large number of passes, the angle needs to be changed several times during the welding process to meet the welding requirements. During welding, the corresponding positioning member 1 can be moved to the groove 101, and the angle that needs to be adjusted by the welding gun 100 each time is controlled to be more correct, which is beneficial to improving the quality of the weld and also beneficial to improving the welding efficiency.

[0048] For example, in some flat welding processes with many passes, the angle needs to be changed three times to meet the welding requirements. In this case, the positioning member 1 in the positioning assembly can be set to multiple, and the positioning angles α of the three positioning members 1 can be 45°, 30° and 15° respectively, which can be used to correct the angle before welding and calibrate the welding process angle.

[0049] In some embodiments, the positioning assembly further includes at least one connecting member 2 connecting two adjacent positioning members 1. This facilitates the placement and removal of the positioning assembly as a whole and is relatively portable.

[0050] In some embodiments, the connecting member 2 may be a magnet or a double-sided suction cup, and is fixed to two adjacent positioning members 1 by magnetic force or adsorption force, so as to facilitate the overall movement and use of the positioning assembly.

[0051] In some embodiments, the connecting member 2 can be supported on the workpiece 10 to be processed and located between two adjacent positioning members 1, and the two adjacent positioning members 1 are both adsorbed on the same connecting member 2. When the positioning member 1 includes a support portion 12 of a cubic structure and a prismatic positioning portion 11, the connecting member 2 can be set as a rectangular parallelepiped magnet and adsorbed on the support portion 12. The length direction of the connecting member 2 is along the length direction of the support portion 12. In the height direction A of the groove 101, the height of the connecting member 2 is less than the height of the positioning member 1. The positioning member 1 and the connecting member 2 adopt this structure in the middle section, which is convenient for the processing and preparation of the positioning member 1 and the connecting member 2, as well as the fixed positioning and separation operations between the connecting member 2 and the positioning member 1.

[0052] In some embodiments, each positioning member 1 is provided with a through hole 13 penetrating the positioning member 1, and the positioning assembly further includes a strip-shaped flexible member (not shown in the figure) passing through each through hole 13 in sequence.

[0053] The flexible member can pass through the through hole 13 of the positioning member 1, and the tie can combine and move at least two positioning members 1 and the connecting member 2 to improve the portability of the positioning assembly.

[0054] In some embodiments, the through hole 13 may be provided on the support portion 12 of the positioning member 1, and a hole corresponding to the through hole 13 may be provided on the connecting member 2 to facilitate overall movement, which is not limited in the present application.

[0055] In some embodiments, the positioning member 1 may be a stainless steel positioning member 1, the thickness of the connecting member 2 in the length direction B of the groove 101 is 10 mm, the three positioning members 1 are arranged side by side, and a connecting member 2 is provided between each adjacent positioning member 1, and the overall thickness of the positioning assembly in the length direction B of the groove 101 is 50 mm. The positioning angles α of the three positioning members 1 may be 45°, 30° and 15° respectively, and the diameter of the through hole 13 may be 10 mm.

[0056] Based on the same inventive concept, the present application provides a device to be processed. The structural diagram of the device to be processed can be referred to Figure 1 and Figure 2 , Figure 1 and Figure 2 The structure of the positioning assembly is shown in FIG. 1 , and the structure of the workpiece 10 to be processed is also shown. The device to be processed includes:

[0057] The workpiece 10 to be processed is provided with a surface 102 to be processed and a groove 101 located on the surface 102 to be processed. The groove 101 has a bottom surface 1011 and two groove surfaces 1012 respectively connected to two sides of the bottom surface 1011 .

[0058] Positioning assembly as previously described.

[0059] The structure of the positioning assembly can be referred to above, and will not be described again. The workpiece 10 to be processed cooperates with the positioning assembly to facilitate welding of the groove 101 .

[0060] In some embodiments, the surface to be processed 102 is connected to the groove surface 1012 and there is an angle. The positioning member 1 also includes a supporting portion 12 connected to the positioning portion 11. The supporting portion 12 has a supporting surface 121 that fits the surface to be processed 102 and is connected to the fitting surface 111.

[0061] There is an angle between the surface to be processed 102 and the groove surface 1012. The supporting surface 121 of the supporting part 12 in the positioning part 1 is in contact with the surface to be processed 102 and is connected to the contact surface 111 of the positioning part 11. Then, there is an angle between the supporting surface 121 of the supporting part 12 and the contact surface 111 of the positioning part 11, and the supporting part 11 can be supported on the surface to be processed 102 and the groove surface 1012 with the angle, which facilitates the positioning of the positioning part 1 and improves the welding accuracy.

[0062] In some embodiments, the positioning assembly further includes a connecting member 2 adsorbed between two adjacent positioning members 1 , and the connecting member 2 is also adsorbed on the workpiece 10 to be processed.

[0063] The connecting member 2 can absorb the workpiece 10 to be processed, cooperate with the supporting surface 121 and the fitting surface 111, realize the rapid positioning and position fixation of the positioning member 1, and improve the welding efficiency.

[0064] In some embodiments, the connector 2 may be a magnet, the workpiece 10 to be processed may be a composite steel workpiece 10 to be processed, the groove surface 1012 may be perpendicular to the bottom surface 1011, and the positioning angle α may be an acute angle. It can be applied to flat welding to improve the quality of flat welding.

[0065] For ease of understanding, the welding process of the device to be processed in some embodiments can be provided here. The positioning member 1 is clamped at the groove 101 position of the workpiece 10 to be processed, and the magnet or magnetic connector 2 is magnetically fixed and fitted with the workpiece 10 to be processed. In the positioning member 1, the positioning portion 11 extends into the groove 101 and abuts against the bottom surface 1011 of the groove 101, so that the second intersection line 113 contacts or nearly overlaps with the first intersection line 1013. The robot welding gun 100 is moved to make the welding wire 1001 gradually approach the positioning plane 112 of the positioning portion 11 and fit it. After angle correction, the welding posture of the robot welding point is stored. An angle ruler can also be used for measurement during the welding process of non-standard parts to ensure that the angle of the welding gun 100 in actual production meets the process requirements. When the positioning angle α of the positioning portion 11 is 30°, the positioning plane 112 of the positioning portion 11 does not fit the welding wire 1001 extending from the welding gun 100 of the robot being measured, indicating that the welding angle does not meet the requirements, and the welding gun 100 needs to be readjusted according to the measured deviation direction before measurement. It can be seen that the utility model is easy to use, simple in structure, low in cost, and can accurately calibrate the welding angle.

[0066] It should be noted that the board surface referred to in this application is the surface with the largest area on the structure where the board surface is located. The parallel or perpendicularity involved in this application is relative to the concept of absolute parallelism or absolute perpendicularity in geometry, and a deviation of 0 to 5 degrees is allowed. This application does not impose any restrictions on this.
