Description

Technical Field

[0001] The present application relates to the technical field of stud welding detection, and in particular to a stud welding detection tool. Background Art

[0002] When welding studs on a workpiece, a stud welding tool is often used to assist in the welding process, preventing dimensional deviation or misalignment. Some workpieces require multiple steps before the studs can be attached to other components. During this process, the studs may be bumped and impacted, affecting their position. However, existing stud welding tools cannot detect stud position and are relatively limited in functionality. Utility Model Content

[0003] In view of this, an embodiment of the present application provides a stud welding detection tool to solve the problem that the existing stud welding tool has relatively single functions.

[0004] The first aspect of the present application proposes a stud welding detection tool, including a base, a positioning member and a gap measurer, wherein the positioning member is arranged on the base so that the base is positioned and installed on the workpiece, and the base is provided with a guide hole for guiding the stud welding gun, and the gap measurer is used to measure the gap between the hole wall of the guide hole and the outer wall of the stud.

[0005] The beneficial effect of the stud welding detection tool provided in the embodiment of the present application is as follows: when welding the stud on the workpiece, the base is first positioned and installed on the workpiece through the positioning piece, and then the end of the stud welding gun is inserted into the guide hole to weld the stud on the workpiece. After the welding is completed, the base is removed; because the stud welding gun is guided by the guide hole, it can be ensured that no dimensional deviation or skew occurs after the stud welding. After the stud is welded on the workpiece and passes through multiple processes, the base can be repositioned and installed on the workpiece through the positioning piece. At this time, an annular gap will be formed between the hole wall of the guide hole and the outer wall of the stud. A gap measuring device is used to select multiple positions on the circumference of the annular gap for measurement. If the measured values ​​at each position are consistent or basically consistent, it means that the stud has not been skewed or offset. If the measured values ​​at each position have large deviations, it means that the stud has been skewed or offset. Therefore, the above-mentioned stud welding detection tool can not only assist in the welding of the stud, but also detect the position of the stud, solving the problem that the existing stud welding tool has a relatively single function.

[0006] In some embodiments, the gap measurer is a feeler gauge.

[0007] The beneficial effect of adopting the above solution is that when detecting the gap, the measurement result can be obtained by simply inserting the feeler gauge into the gap between the hole wall of the guide hole and the outer wall of the stud, and the operation is relatively simple.

[0008] In some embodiments, the feeler gauge is a wedge-shaped feeler gauge.

[0009] The beneficial effect of adopting the above solution is that one wedge-shaped feeler gauge can measure different gaps. Compared with a single-piece feeler gauge, there is no need to repeatedly replace it, thereby improving measurement efficiency.

[0010] In some embodiments, the base is a substrate, and a plurality of the guide holes are provided on the substrate.

[0011] The beneficial effect of adopting the above solution is that by providing a plurality of guide holes on the substrate, a plurality of studs can be welded simultaneously, which not only ensures the accurate position of each stud, but also ensures the accurate distance between two adjacent studs.

[0012] In some embodiments, a handle is provided on the substrate, and the guide holes are respectively provided on both sides of the handle.

[0013] The beneficial effects of adopting the above scheme are: by providing a handle on the substrate, it is convenient to take, place and carry the tooling; and by providing guide holes on both sides of the handle, the weight difference of the substrates on both sides of the handle will not be too large. When the tooling is carried by the handle, it is beneficial to balance the force on both sides of the handle, and the tooling will not tilt significantly due to the heavier side.

[0014] In some embodiments, the guide holes have holes that are higher than the surface of the substrate where the guide holes are located.

[0015] The beneficial effect of adopting the above scheme is: since the guide hole for guiding the stud welding gun needs to have a certain axial length, through the above design, while ensuring that the guide hole has a certain axial length, the thickness of the base plate can be reduced, which is conducive to reducing the weight of the tooling.

[0016] In some embodiments, the base is a plastic base.

[0017] The beneficial effects of adopting the above solution are: compared with a metal seat, designing the base as a plastic seat can further reduce the weight of the tooling; moreover, the plastic seat will not cause damage to the workpiece.

[0018] In some embodiments, the positioning member is a positioning column, and a plurality of the positioning columns are provided.

[0019] The beneficial effect of adopting the above solution is that the positioning of the base can be achieved by inserting the positioning column into the positioning hole on the workpiece, making the positioning of the base simple and quick.

[0020] In some embodiments, the stud welding inspection tool further includes a connecting rope, one end of the connecting rope is connected to the gap measurer, and the other end of the connecting rope is connected to the base.

[0021] The beneficial effect of adopting the above solution is that the gap measuring device is connected to the base by using a connecting rope, thereby preventing the gap measuring device from being lost, and the gap measuring device can be carried together with the base.

[0022] In some embodiments, the base is made by 3D printing.

[0023] The beneficial effect of adopting the above solution is that the base is made by 3D printing, which shortens the production cycle of the base and reduces the production cost of the base.

[0024] The above description is only an overview of the technical solution of the present application. In order to more clearly understand the technical means of the present application, it can be implemented in accordance with the contents of the specification.

Those skilled in the art can understand the specific meanings of the above terms in the embodiments of the present application based on specific circumstances.

[0050] The embodiment of the first aspect of the present application provides a stud welding detection tool. Figure 1 、 Figure 4 、 Figure 5 and Figure 6 The stud welding inspection tool 10 includes a base 11, a positioning member 12, and a gap measuring device 13. The positioning member 12 is provided on the base 11 to position the base 11 on the workpiece 20. The base 11 is provided with a guide hole 114 for guiding the stud welding gun 30. The gap measuring device 13 is used to measure the gap between the hole wall of the guide hole 114 and the outer wall of the stud 40.

[0051] The positioning member 12 is provided on the base 11. It can be understood that the positioning member 12 can be integrally formed with the base 11; or, the positioning member 12 can also be fixed on the base 11, for example, the positioning member 12 is fixed to the base 11 by welding, threaded connection, clamping, interference connection and fastener connection.

[0052] Optionally, the positioning member 12 is located on the side of the base 11 facing the workpiece 20, and the positioning member 12 is positioned and matched with the positioning matching portion 21 on the workpiece 20 to position and install the base 11 on the workpiece 20; for example, the positioning member 12 is a positioning column, and the positioning matching portion 21 on the workpiece 20 is a positioning hole. There can be one or more positioning members 12.

[0053] It can be understood that the base 11 can be a plate-shaped structure, and one or more guide holes 114 can be set on the base 11. In this case, multiple positioning members 12 can be arranged arbitrarily on the base 11; or, the base 11 can be a cylindrical structure, and one guide hole 114 can be set on the base 11, and multiple positioning members 12 are arranged at intervals along the circumference of the base 11.

[0054] When welding the stud 40, Figure 5 As shown, the guide hole 114 is provided for inserting the end of the stud welding gun 30 to guide the stud welding gun 30, thereby ensuring that the stud 40 after welding does not have dimensional deviation or skew. The guide hole 114 is adapted to the end of the stud welding gun 30. Optionally, the guide hole 114 is a circular hole. In this case, the diameter of the guide hole 114 can be approximately 0.1 mm larger than the diameter of the end of the stud welding gun 30. This facilitates the insertion of the end of the stud welding gun 30 into the guide hole 114 and ensures that the position of the stud 40 after welding is within the error range.

[0055] After the stud 40 is welded, Figure 6 As shown, an annular gap is formed between the hole wall of the guide hole 114 and the outer wall of the stud 40. By measuring the gap values ​​of each position of the annular gap using the gap measuring device 13 to see whether they are the same, it is possible to detect whether the stud 40 is offset or skewed after welding.

[0056] The stud welding inspection tool 10 provided in the embodiment of the present application has the following beneficial effects: when welding the stud 40 to the workpiece 20, the base 11 is first positioned and installed on the workpiece 20 using the positioning member 12, and then the end of the stud welding gun 30 is inserted into the guide hole 114 to weld the stud 40 to the workpiece 20. After welding is completed, the base 11 is removed. Since the stud welding gun 30 is guided by the guide hole 114, it can be ensured that the stud 40 will not have dimensional deviation or skew after welding. After the stud 40 is welded to the workpiece 20 and undergoes multiple steps, the base 11 can be repositioned and installed on the workpiece 20 using the positioning member 12. At this time, an annular gap is formed between the hole wall of the guide hole 114 and the outer wall of the stud 40. The gap measuring device 13 is used to select multiple positions along the circumference of the annular gap for measurement. If the measured values ​​at each position are consistent or substantially consistent, it indicates that the stud 40 has not skewed or offset. If the measured values ​​at each position deviate significantly, it indicates that the stud 40 has skewed or offset. Therefore, the stud welding detection tool 10 can not only assist in welding the stud 40 , but also detect the position of the stud 40 , thereby solving the problem of the existing stud welding tool having a relatively single function.

[0057] Please also refer to Figures 1 to 3 In some embodiments, the gap measurer 13 is a feeler gauge.

[0058] When detecting the gap, it is only necessary to insert a feeler gauge into the gap between the hole wall of the guide hole 114 and the outer wall of the stud 40 to obtain the measurement result, and the operation is relatively simple.

[0059] In other embodiments, the gap measuring device 13 may be a vernier caliper, a micrometer, or the like.

[0060] Please refer to Figure 1 In some embodiments, the feeler gauge is a wedge-shaped feeler gauge.

[0061] One end of the wedge-shaped feeler gauge is narrower and the other end is wider. A scale is provided along its length. By reading the scale value on the wedge-shaped feeler gauge, the gap value between the hole wall of the guide hole 114 and the outer wall of the stud 40 can be obtained.

[0062] The wedge-shaped feeler gauge is generally made of metal material to prevent the wedge-shaped feeler gauge from being deformed, ensure the wear resistance of the wedge-shaped feeler gauge, and increase the service life of the wedge-shaped feeler gauge.

[0063] It can be understood that the wedge-shaped feeler gauge can be an ordinary wedge-shaped feeler gauge, which requires human eyes to observe the scale and read the value; the wedge-shaped feeler gauge can also be a digital wedge-shaped feeler gauge, which can directly display the measurement value, facilitate reading the value, and reduce or avoid errors caused by human eye observation.

[0064] Since one wedge-shaped feeler gauge can measure different gaps, compared to a single-piece feeler gauge, there is no need to repeatedly replace it, which improves measurement efficiency.

[0065] In other embodiments, the feeler gauge may be a single-piece feeler gauge composed of a group of thin sheets with different thickness differences, and the gap is measured by using thin sheets of different thicknesses or combining two thin sheets.

[0066] Please refer to Figure 1 In some embodiments, the base 11 is a substrate, and a plurality of guide holes 114 are provided on the substrate.

[0067] It is understood that there may be two, three or four guide holes 114, etc. Optionally, the guide holes 114 are circular holes, and the diameters of the guide holes 114 may be the same or different.

[0068] It is understandable that the guide hole 114 can be directly formed when the substrate is processed, or can be cut and formed by a cutting device after the substrate is processed.

[0069] The base plate is contoured according to the shape of the workpiece 20. Optionally, the base plate includes a first side panel section 111, an intermediate panel section 112, and a second side panel section 113. The intermediate panel section 112 is located between the first side panel section 111 and the second side panel section 113, and the intermediate panel section 112 is higher than the first side panel section 111 and the second side panel section 113. It is understood that the first side panel section 111 can be higher than the second side panel section 113, or the first side panel section 111 and the second side panel section 113 can be at the same height. A guide hole 114 is provided in the first side panel section 111, and two guide holes 114 are provided in the second side panel section 113. Of course, the base plate can also be a flat plate structure as a whole, that is, each position of the base plate is at the same height.

[0070] It can be understood that a positioning member 12 is provided on one of the first side panel segment 111, the middle panel segment 112 and the second side panel segment 113, for example, a positioning member 12 is provided on the middle panel segment 112; or, a positioning member 12 is provided on two of the first side panel segment 111, the middle panel segment 112 and the second side panel segment 113; or, a positioning member 12 is provided on three of the first side panel segment 111, the middle panel segment 112 and the second side panel segment 113.

[0071] Optionally, the substrate should have a certain thickness. For example, the thickness of the substrate may be about 5 mm. This ensures that the substrate has a certain strength and will not be deformed, and the weight of the substrate will not be too large.

[0072] By providing a plurality of guide holes 114 on the substrate, a plurality of studs 40 can be welded at one time, which not only ensures the accuracy of the position of each stud 40 but also ensures the accuracy of the distance between two adjacent studs 40 .

[0073] In other embodiments, please refer to Figure 3 , a guide hole 114 can be set on the substrate.

[0074] Please refer to Figure 1 In some embodiments, a handle 14 is provided on the substrate, and guide holes 114 are respectively provided on both sides of the handle 14.

[0075] Optionally, the base plate includes a first side panel section 111, a middle panel section 112 and a second side panel section 113, and the handle 14 is provided on the middle panel section 112. Since the first side panel section 111 and the second side panel section 113 are respectively provided on both sides of the middle panel section 112, when the tooling is taken and placed by the handle 14, the tooling will not tilt significantly due to one side being heavier.

[0076] It is understandable that the handle 14 can be integrally formed with the base plate; or, the handle 14 can be fixed to the base plate, for example, the handle 14 is fixed to the base plate by welding, threaded connection, clamping, interference connection, etc.

[0077] In this embodiment, the structure of the handle 14 is not limited. For example, the handle 14 may be U-shaped; or, the handle 14 may be T-shaped; or, the handle 14 may be in a straight line shape.

[0078] By providing a handle 14 on the substrate, it is convenient to take, place and carry the tooling; and guide holes 114 are provided on both sides of the handle 14 so that the weight difference of the substrates on both sides of the handle 14 will not be too large. When the tooling is carried by the handle 14, it is beneficial to balance the force on both sides of the handle 14, and the tooling will not tilt significantly due to one side being heavier.

[0079] In other embodiments, the handle 14 may not be provided on the substrate. In this case, the substrate may be picked up and placed using an adsorption component on the robot, wherein the adsorption component may be a vacuum adsorption component or a magnetic adsorption component; when it is a magnetic adsorption component, the substrate is made of iron material.

[0080] Please refer to Figure 1 In some embodiments, the edge 115 of the guide hole 114 is higher than the surface of the substrate where the guide hole 114 is located.

[0081] Optionally, a guide hole 114 is provided on the first side panel segment 111, that is, the hole edge 115 of the guide hole 114 on the first side panel segment 111 is higher than the surface of the first side panel segment 111; a guide hole 114 is provided on the second side panel segment 113, that is, the hole edge 115 of the guide hole 114 on the second side panel segment 113 is higher than the surface of the second side panel segment 113.

[0082] In this embodiment, since the guide hole 114 for guiding the stud welding gun 30 needs to have a certain axial length, the above design can reduce the thickness of the substrate while ensuring that the guide hole 114 has a certain axial length, which is beneficial to reducing the weight of the tooling.

[0083] In other embodiments, the thickness of the substrate may be the same as the axial length of the guide hole 114 . In this case, the edge 115 of the guide hole 114 is flush with the surface of the substrate where the guide hole 114 is located.

[0084] In some embodiments, the base 11 is a plastic base.

[0085] The plastic seat can be made of plastics such as nylon, polytetrafluoroethylene, polyethylene, etc.

[0086] Since plastic is relatively light, designing the base 11 as a plastic seat can further reduce the weight of the tooling. Moreover, compared to metal materials, the plastic seat will not cause damage to the workpiece 20.

[0087] In other embodiments, the base 11 may be a metal base, for example, the metal base is made of metal such as steel, iron, or aluminum.

[0088] In some embodiments, the positioning member 12 is a positioning column, and a plurality of positioning columns are provided.

[0089] It can be understood that the lower end of the positioning column can be a conical structure to facilitate the positioning column to be inserted into the positioning hole of the workpiece 20; or, the lower end of the positioning column can also be a hemispherical structure; or, the lower end of the positioning column can be a cylindrical structure, but a flared structure is provided at the opening of the positioning hole of the workpiece 20.

[0090] The positioning pin is inserted into the positioning hole on the workpiece 20 to realize the positioning of the base 11, so that the positioning of the base 11 is simple and fast.

[0091] In other embodiments, the positioning member 12 may be a positioning block.

[0092] Please refer to Figure 2 In some embodiments, the stud welding inspection tool 10 further includes a connecting rope 15 , one end of the connecting rope 15 is connected to the gap measuring device 13 , and the other end of the connecting rope 15 is connected to the base 11 .

[0093] Optionally, a connecting hole 131 is provided at one end of the gap measurer 13 , a handle 14 is provided on the base 11 , one end of the connecting rope 15 is connected to the gap measurer 13 through the connecting hole 131 , and the other end of the connecting rope 15 is connected to the base 11 through the handle 14 .

[0094] Optionally, the connecting rope 15 has a certain degree of elasticity, that is, the connecting rope 15 is an elastic rope; in this way, even if the connecting rope 15 is relatively short, it can still be inserted into the gap between the hole wall of the guide hole 114 and the outer wall of the stud 40. Of course, the connecting rope 15 can also have no elasticity, in which case the connecting rope 15 needs to be designed to be longer.

[0095] The gap measurer 13 is connected to the base 11 by a connecting rope 15 to prevent the gap measurer 13 from being lost. At the same time, the gap measurer 13 can be carried together with the base 11 .

[0096] In other embodiments, instead of the connecting rope 15, a placement slot may be provided on the base 11, the slot of which is provided with a cover plate, and the gap measuring device 13 is placed in the placement slot; when in use, the cover plate is opened and the gap measuring device 13 is taken out of the placement slot. After use, the gap measuring device 13 is put back into the placement slot and the cover plate is closed to prevent the gap measuring device 13 from being lost. At the same time, the gap measuring device 13 can be carried together with the base 11. Alternatively, please refer to Figure 1 Neither a connecting rope 15 nor a placement slot is provided, and the gap measuring device 13 is independently placed and transported.

[0097] In some embodiments, the base 11 is made by 3D printing.

[0098] 3D printing, or three-dimensional printing, also known as additive manufacturing technology, is a technology that manufactures physical parts by adding materials layer by layer based on three-dimensional CAD data.

[0099] It is understood that the positioning member 12 can be 3D printed together with the base 11; alternatively, the positioning member 12 can be fixed to the base 11 after the base 11 is 3D printed. Similarly, the handle 14 can be 3D printed together with the base 11; alternatively, the handle 14 can be fixed to the base 11 after the base 11 is 3D printed.

[0100] The base 11 is manufactured by 3D printing, which shortens the manufacturing cycle of the base 11 and reduces the manufacturing cost of the base 11 .

[0101] In other embodiments, the base 11 may be formed by machining or casting.

[0102] In some embodiments, the workpiece 20 is a vehicle body. Specifically, the vehicle body technician first positions and installs the base 11 on the vehicle body using the positioning member 12. The technician then inserts the end of the stud welding gun 30 into the guide hole 114 to weld the stud 40 to the vehicle body. Because the vehicle body undergoes multiple processing steps after the studs 40 are welded, the condition of the studs 40 on the vehicle body cannot be determined. Therefore, the final assembly technician uses the base 11 and the gap gauge 13 to check the position of the studs 40. If the studs 40 are offset or skewed, the final assembly technician will collect the problematic studs 40 and provide feedback to the vehicle body technician.

[0103] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present application, and should all be included in the scope of protection of the present application.
