Description

Technical Field

[0001] The present disclosure relates generally to the correction and maintenance of machine tools. More particularly, the present disclosure relates to a correction device, particularly a correction device for a welding gun. Background Art

[0002] Welding equipment is widely used in the field of mechanical manufacturing. Welding with welding equipment is one of the most effective ways to connect two objects together.

[0003] A welding gun is a type of welding equipment. A common welding gun generally includes a welding handle, a generally tubular gun body, and a generally tubular gun head. The gun head may be angled relative to the gun body, and a welding wire may be installed in a welding wire cavity of the gun head. A welding gun may include a MIG welding gun (metal inert gas shielded welding gun), a MAG welding gun (metal active gas shielded welding gun), or other types of welding guns. A welding gun may be held by a worker for manual welding, or held by a robot for automatic welding.

[0004] During use, the welding gun may collide with surrounding objects due to operating errors or interference from surrounding objects, which may cause the gun body or gun head of the welding gun to deform, resulting in, for example, a change in the angle of the gun head relative to the gun body. The above deformation of the welding gun or the change in the angle of the gun head will have an adverse effect on the welding position, welding quality, etc. In particular, for automatic welding performed by a robot, it is necessary to require the gun head of the welding gun to always be in a precise position to accurately control the welding trajectory to ensure the quality of the welded product, and the above deformation of the welding gun or the change in the angle of the gun head makes it difficult to accurately control the welding trajectory. Therefore, before use, the welding gun usually needs to be corrected.

[0005] Most of the existing correction devices generally use a limiting component to clamp the welding gun, and then the worker directly moves or bends the corresponding component of the welding gun by hand to correct it. This method is not only difficult to ensure the accuracy and effect of the correction, but also easily causes unnecessary damage to the welding gun, thereby reducing the service life of the welding gun.

[0006] It should be noted that the subject matter claimed herein is not limited to the areas described above, is not limited to only solving any disadvantages mentioned above, and is not limited to embodiments used or operated only in environments such as those described above.

[0034] The present disclosure will be described below with reference to the accompanying drawings, in which several embodiments of the present disclosure are shown. However, it should be understood that the present disclosure can be presented in many different ways and is not limited to the embodiments described below; in fact, the embodiments described below are intended to make the disclosure of the present disclosure more complete and to fully explain the scope of protection of the present disclosure to those skilled in the art. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide more additional embodiments.

[0035] It should be understood that the terms used in the specification are only for describing specific embodiments and are not intended to limit the present disclosure. All terms used in the specification (including technical terms and scientific terms) have the meanings commonly understood by those skilled in the art unless otherwise defined. For the sake of brevity and / or clarity, well-known functions or structures may not be described in detail.

[0036] As used in the specification, the singular forms "a", "the", and "said" include the plural forms unless clearly indicated otherwise. The terms "comprising", "including", and "containing" as used in the specification denote the presence of the claimed features, but do not preclude the presence of one or more other features. The term "and / or" as used in the specification includes any and all combinations of one or more of the associated listed items.

[0037] In the specification, when an element is referred to as being "on", "attached" to, "connected" to, "coupled" to, or "in contact" with another element, etc., that element can be directly on, attached to, connected to, coupled to, or in contact with the other element, or there can be intervening elements.

[0038] In the specification, the terms "first", "second", "third", etc. are used for convenience only and are not intended to be limiting. Any technical features represented by "first", "second", "third", etc. are interchangeable.

[0039] In the specification, spatial relationship terms such as "above", "below", "front", "rear", "top", "bottom", etc. can describe the relationship of one feature to another feature in the drawings. It should be understood that the spatial relationship terms include different orientations of the device during use or operation in addition to the orientations shown in the drawings. For example, when the device in the drawing is inverted, a feature originally described as "below" other features can then be described as "above" the other features. The device can also be oriented in other ways (rotated 90 degrees or in other orientations), and the relative spatial relationships will be interpreted accordingly at that time.

[0040] The present disclosure relates to a correction device that can be used to correct a welding torch. The welding torch can be, for example, Figure 1 , Figure 3 , Figure 6 and Figure 7 as more clearly shown by the welding torch 1, which can include a torch handle 10, a gun body 11, and a gun head 12. The gun body 11 can be generally tubular and is connected between the torch handle 10 and the gun head 12. In other words, one end of the gun body 11 is connected to the gun head 12, and the other end is connected to the torch handle 10. The cavity 11 can include a bent portion such that the gun head 12 can be angled relative to the gun body 11. The gun head 12 can also be generally tubular and can include one or more wire cavities. A welding wire 13 can be installed in the wire cavity of the gun head 12. The welding torch 1 can be a MIG welding torch, a MAG welding torch, or other types of welding torches.

[0041] Referring to Figures 1 to 4, the correction device 2 according to some embodiments of the present disclosure will be described. The correction device 2 may include a fixing element 21 for positioning the welding torch 1, an alignment element 22 for providing a correction reference position, and a correction assembly 23.

[0042] The fixing element 21 may position the welding torch 1 by fixing the handle 10 of the welding torch 1. In some embodiments, for example, the fixing element 21 may include a circular hole (not shown in the figure) for accommodating and fixing the handle 10 of the welding torch 1, and the handle 10 of the welding torch 1 may be fastened in the circular hole of the fixing element 21 in an appropriate manner to position the welding torch 1. In other embodiments, the handle 10 of the welding torch 1 may be fastened to the fixing element 21 by fastening elements (such as fastening screws or nuts) to position the welding torch 1.

[0043] The alignment element 22 may be disposed at a predetermined position near the tip 12 of the welding torch 1 at a distance from the fixing element 21 to provide a correction reference position for the tip 12 of the welding torch 1. When the tip 12 of the welding torch 1 is aligned with the correction reference position of the alignment element 22 of the counter-rotating element, it can be considered that the tip 12 of the welding torch 1 has been corrected. As Figure 3 more clearly shown, the alignment element 22 may include an elongated end 221. The elongated end 221 may be used to provide a correction reference position. During correction, it is necessary to align, for example, the center of the tip 12 of the welding torch 1 or the welding wire 13 in the tip 12 with the end 221 of the alignment element 22.

[0044] In some embodiments, the position of the alignment element 22 relative to the fixing element 21 may be adjusted so that the correction device 2 can be applied to different types of welding torches. This helps to enhance the versatility of the correction device 2.

[0045] The correction assembly 23 may include a grasping element 231, a driving mechanism 232 for driving the grasping element 231 to move, and a connecting rod element 233 connected between the driving mechanism 232 and the grasping element 231. The driving mechanism 232 may be configured to be able to move the connecting rod element 233 up and down along the vertical direction Z, move left and right along the transverse direction Y perpendicular to the vertical direction Z and parallel to the connecting rod element 233, and move back and forth along the longitudinal direction X perpendicular to both the vertical direction Z and the transverse direction Y. The grasping element 231 is configured to be able to move following the movement of the connecting rod element 233, so as to be able to drive the tip 12 of the welding torch 1 to move to a position substantially aligned with the correction reference position of the alignment element 22 to correct the welding torch 1. With the help of the driving mechanism 232, a controlled correction of the tip 12 of the welding torch 1 can be implemented, which can not only improve the correction accuracy but also avoid damaging the welding torch 1, which will be described in detail below.

[0046] Referring to Figure 1, in some embodiments, the grasping element 231 may include a lumen having a cross-section in the form of a running track (with a rectangular middle part and semi-circular end parts) and a notch leading to the lumen. At least a part of the welding torch 1 (for example, the torch body 11 or the torch tip 12) can enter the lumen of the grasping element 231 via the notch and be held in, for example, the semi-circular end part of the lumen, so as to be grasped by the grasping element 231. The notch may be provided in the rectangular middle part of the grasping element 231 and may be provided above or below the lumen of the grasping element 231. The grasping element 231 having such a structure is very simple and practical. In other embodiments, the grasping element 231 may have other structures. For example, the grasping element 231 may be configured to include two claw parts that can open and close relative to each other to grasp the welding torch 1.

[0047] Continue to refer to Figures 1 to 4, the specific structure of the driving mechanism 232 will be described. In some embodiments, the driving mechanism 232 may include a guide rail 240 extending along the longitudinal direction X, a first movable member 250 extending along the vertical direction Z, and a second movable member 260 extending along the transverse direction Y. The bottom end of the first movable member 250 may be slidably positioned on the guide rail 240 such that the first movable member 250 can move back and forth along the guide rail 240 in the longitudinal direction X. The first movable member 250 may include a first lead screw 251 extending along the vertical direction Z, and the first lead screw 251 can rotate about the vertical direction Z. The second movable member 260 may be movably sleeved on the first lead screw 251 and can move up and down along the first lead screw 251 in the vertical direction Z when the first lead screw 251 rotates. The second movable member 260 may include a second lead screw 261 extending along the transverse direction Y, and the second lead screw 261 can rotate about the transverse direction Y. The link element 233 may be movably sleeved on the second lead screw 261 and can move left and right along the second lead screw 261 in the transverse direction Y when the second lead screw 261 rotates. To this end, one end of the link element 233 away from the grasping element 231 may include a bent portion such that the link element 233 is generally in an "L" shape. The bent portion of the link element 233 may be sleeved on the second lead screw 261. Such a driving mechanism 232 can achieve multi-degree-of-freedom movement of the link element 233 and the grasping element 231 connected thereto in multiple directions in three-dimensional space, thereby enabling more flexible correction. For example, the grasping element 231 can move back and forth along the longitudinal direction X under the drive of the driving mechanism 232 via the link element 233, so that it can be accurately moved to the part of the welding torch 1 to be corrected to grasp the welding torch; the grasping element 231 can move up and down along the vertical direction Z under the drive of the driving mechanism 232 via the link element 233 to correct the height of the tip 12 of the welding torch 1; and the grasping element 231 can move left and right along the transverse direction Y under the drive of the driving mechanism 232 via the link element 233 to correct the angle of the tip 12 of the welding torch 1.

[0048] In addition, the movement of the gripping element 231 along the vertical direction Z and the lateral direction Y is respectively achieved by rotating the first lead screw 251 and the second lead screw 261, which enables the movement of the gripping element 231 along the vertical direction Z and the lateral direction Y to have very high precision, thus contributing to more precise correction. Specifically, the outer surfaces of the first lead screw 251 and the second lead screw 261 both include threads, and the pitch between adjacent threads determines the distance that the gripping element 231 moves per revolution of the first lead screw 251 and the second lead screw 261. By controlling the pitch between adjacent threads, precise movement of the gripping element 231 can be achieved, and thus precise correction of the welding torch 1 can be realized. Moreover, the pitch between adjacent threads is usually very small, which makes the distance that the gripping element 231 moves per revolution of the first lead screw 251 and the second lead screw 261 also very small, which can avoid unexpected damage to the welding torch 1, and thus can effectively protect the welding torch 1 during the correction process.

[0049] In some embodiments, the first movable member 250 may include a first rotating wheel 252 for rotating the first lead screw 251. The first rotating wheel 252 may be disposed at the top end of the first movable member 250 for convenient operation of the first rotating wheel. Similarly, the second movable member 260 may include a second rotating wheel 262 for rotating the second lead screw 262. The second rotating wheel 262 may be disposed at an end of the second movable member 250 away from the gripping element 231 to facilitate operation of the second rotating wheel. In some embodiments, the first rotating wheel 252 may include a first handle 253, and the second rotating wheel 262 may include a second handle 263. The first rotating wheel 252 can be rotated by means of the first handle 253 and the second rotating wheel 262 can be rotated by means of the second handle 263, which can enhance the operability of the correction device 2.

[0050] In other embodiments, the first movable member 250 and the second movable member 260 may not include the first rotating wheel 252 and the second rotating wheel 262 respectively, but include other rotating components. For example, the first movable member 250 and the second rotatable member 260 may include a first knob and a second knob respectively. In addition, the first rotating wheel 252 and the second rotating wheel 262 may also be disposed at other different positions as long as they can rotate the first lead screw 251 and the second lead screw 261 respectively.

[0051] In some embodiments, the correction device 2 may include a platform 24. The fixing element 21 and the alignment element 22 may be detachably fixed on the platform 24, and at least a part of the correction assembly 23 may be movably disposed on the platform 24. For example, in Figure 1In the illustrated embodiment, the guide rail 240 of the drive mechanism 232 of the correction assembly 23 can be fixed to the platform 24, while the other parts of the correction assembly 23 can move relative to the platform 24. The platform 24 can include multiple parts, and the heights between the respective parts can be different. As Figure 1 shown, the platform 24 can include two parts, where the height of one part can be higher than that of the other part. Of course, the platform 24 can also include only one part, or can include multiple parts with the same height.

[0052] Next, referring to Figure 5 , when using the correction device 2 according to the present disclosure, generally, the grasping element 231 and the link element 233 of the correction assembly 23 are kept in a straight line and extend perpendicular to the gun body 11 of the welding torch 1. During the correction operation, the grasping element 231 and the link element 233 also need to be fixed to each other and maintain such a positional relationship. This can more precisely control the moving distance of the grasping element 231 in each direction, thereby achieving more precise correction.

[0053] However, as Figure 6 shown, when the gun body 11 of the welding torch 1 includes a bent portion, in some cases, the grasping element 231 may need to grasp the bent portion of the gun body 11 to perform correction. In this case, the angle of the grasping element 231 relative to the link element 233 needs to be adjusted so that the correction device 2 can operate. For this purpose, in some embodiments, the grasping element 231 can be configured to pivot a predetermined angle about the vertical direction Z relative to the link element 233 so that it can grasp the bent portion of the gun body 11 of the welding torch 1. For example, the grasping element 231 can be configured to be pivotally connected to the link element 233 via a pivot 234.

[0054] After the grasping element 231 pivots a predetermined angle about the vertical direction Z relative to the link element 233, the grasping element 231 also needs to be fastened at its pivoted position. For this purpose, in some embodiments, the grasping element 231 can further include a fastening element (not shown in the figure), and the grasping element 231 is fastened at its pivoted position by using this fastening element. In some embodiments, the fastening element can be configured as a fastening pin. Correspondingly, as Figure 5 and Figure 6 shown, the connecting portion of the grasping element 231 and the connecting portion of the link element 233 can respectively include one or more positioning holes 235. After the grasping element 231 pivots a predetermined angle about the vertical direction Z relative to the link element 233, the fastening pin can be inserted into the mutually aligned positioning holes 235 of the grasping element 231 and the link element 233 to fasten the grasping element 231 at its pivoted position.

[0055] Referring to Figure 7, in some embodiments, in order to visually indicate whether the tip 12 of the welding torch 1 has been corrected to a desired height, the correction device 2 may further include a height indicating element 25 for indicating the correction height. The height indicating element 25 may have height scales and may be vertically arranged at a desired position, such as vertically fixed on the platform 24.

[0056] Referring to Figure 8 , in some embodiments, in order to visually indicate whether the tip 12 of the welding torch 1 has been corrected to a desired angle, the correction device 2 may further include an angle indicating element 26 for indicating the correction angle. The angle indicating element 26 may have angle scales and may be horizontally arranged at a desired position, such as horizontally arranged on the platform 24.

[0057] The above has described the correction device 2 according to the present disclosure with reference to the welding torch 1. However, it should be noted that the correction device 2 according to the present disclosure is not only used for correcting the welding torch 1, but can be used for correcting any other suitable components. For example, the correction device 2 can be used for correcting other components having a similar structure to the welding torch 1. In particular, the correction device 2 can also be used for correcting components having a similar structure only to the body 11 and / or the tip 12 of the welding torch 1, such as components including a tubular or rod-shaped portion.

[0058] The above has described the exemplary embodiments according to the present disclosure with reference to the drawings. However, those skilled in the art should understand that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure. All such changes and modifications are included within the protection scope of the present disclosure defined by the claims. The present disclosure is defined by the appended claims, and equivalents of these claims are also included.
