According to the welding gun clamping mechanism 110 provided by the embodiment of the application, the first clamping piece 112 and the second clamping piece 113 are respectively connected with the mounting plate 111, so that the clamping pieces and the mounting plate 111 are of an integrated structure, and the parts are prevented from being lost. When the clamping cavity is opened, the rotatable first clamping piece 112 and/or the rotatable second clamping piece 113 are/is rotated around the mounting plate 111, which means that when only the first clamping piece 112 adopts the rotatable connection, the first clamping piece 112 is rotated around the mounting plate 111; when only the second clamping member 113 is rotatably connected, rotating the second clamping member 113 about the mounting plate 111; when the first clamping member 112 and the second clamping member 113 are both rotatably connected, rotating at least one of the first clamping member 112 and the second clamping member 113 around the mounting plate 111; just can make first holder 112 and second holder 113 can keep away from each other or be close to under the above-mentioned rotation operation, and the fixed operation of centre gripping to welder 200 is convenient, and first holder 112 and second holder 113 are difficult to warp at the in-process of putting into and centre gripping welder 200 simultaneously to also can firmly carry out the centre gripping fixedly to welder 200 in a long-term.
In some alternative embodiments, the first clamping member 112 and the second clamping member 113 are rotatably connected to the mounting plate 111, so that the relative positions of the first clamping member 112 and the second clamping member 113 can be adjusted more conveniently, and the adjustable range is larger.
Illustratively, the mounting plate is provided with a first rotating through hole and a second rotating through hole. The first rotating through hole is rotatably provided with a first rotating shaft 1111 in a penetrating manner, one end of the first clamping member 112 close to the mounting plate 111 is sleeved on the first rotating shaft 1111, and optionally, one end of the first clamping member 112 close to the mounting plate 111 is sleeved on two ends of the first rotating shaft 1111.

The mode that rotatable coupling is realized to first pivot 1111 and second pivot 1112 wearing to locate first rotation through-hole and second rotation through-hole can be conveniently with first holder 112 and second holder 113 at mounting panel 111 carry out erection joint.
It should be noted that, whether one or both of the first clamping member 112 and the second clamping member 113 are rotatably connected to the mounting plate 111, when the first clamping member 112 and/or the second clamping member 113 are rotatably connected to the mounting plate 111, the manner of the rotatable connection is not limited, and for example, but not limited to, the connection is performed by using a pin, a hinge, a rotary joint, etc.
In some optional embodiments, an inner wall bus of the first arc plate 1121 is parallel to an inner wall bus of the second arc plate 1131, the inner wall bus of the first arc plate 1121, that is, a bus of the arc inner peripheral wall of the first arc plate 1121 close to one side of the second arc plate 1131, and the inner wall bus of the second arc plate 1131, that is, a bus of the arc inner peripheral wall of the second arc plate 1131 close to one side of the first arc plate 1121, are arranged in such a way that the inner wall of the first arc plate 1121 and the inner wall of the second arc plate 1131 extend along substantially the same direction, so as to be well attached to the welding gun 200.
Further, the inner wall arc radius of the first arc plate 1121 and the inner wall arc radius of the second arc plate 1131 are substantially the same as the radius of the welding gun 200, so that the inner wall of the first arc plate 1121 and the inner wall of the second arc plate 1131 have relatively consistent radians with the outer wall of the welding gun 200, and can be better matched, and therefore, the clamping is more stable and firm.
For example, when the first clamping member 112 and/or the second clamping member 113 are/is rotatably connected to the mounting plate 111, in the case that the inner wall generatrix of the first arc plate 1121 is parallel to the inner wall generatrix of the second arc plate 1131, the rotation axis of the rotatably arranged clamping member is parallel to the inner wall generatrix of the rotatably arranged clamping member. When the first clamping member 112 and the second clamping member 113 are rotatably connected to the mounting plate 111, i.e. the rotation axis of the first clamping member 112 is parallel to the rotation axis of the second clamping member 113, the inner wall generatrix of the first arc plate 1121 is parallel to the rotation axis of the first clamping member 112, and the inner wall generatrix of the second arc plate 1131 is parallel to the rotation axis of the second clamping member 113. In the above arrangement, when the first clamping member 112 and/or the second clamping member 113 rotate to any relative position with respect to the mounting plate 111, the rotation axis of the first clamping member 112, the rotation axis of the second clamping member 113, the inner wall generatrix of the first arc-shaped plate 1121, and the inner wall generatrix of the second arc-shaped plate 1131 all can be kept parallel to each other. When the clamping device is used for clamping the welding gun 200, the first clamping piece 112 and the second clamping piece 113 can be well attached to two opposite side walls of the welding gun 200, so that the welding gun 200 can be firmly clamped and fixed.
The detachable connection of the free end of the first clamping member 112 and the free end of the second clamping member 113 is not limited, such as but not limited to, snap, pin, fastening, etc.
In some optional embodiments, the free end of the first clamping member 112 is provided with a first connection plate 1122, the free end of the second clamping member 113 is provided with a second connection plate 1132 corresponding to the first connection plate 1122, and the first connection plate 1122 and the second connection plate 1132 are detachably connected. The arrangement of the first connecting plate 1122 and the second connecting plate 1132 avoids the interference between the free end of the first clamping member 112 and the free end of the second clamping member 113 caused by the first arc plate 1121 and the second arc plate 1131, so that the free end of the first clamping member 112 can be conveniently and stably connected with the free end of the second clamping member 113. Meanwhile, the interference of the joint to the first arc plate 1121 and the second arc plate 1131 when the welding gun 200 is clamped can also be avoided.
Further, the first connecting plate 1122 is provided with a first connecting hole 1123, the second connecting plate 1132 is provided with a second connecting through hole 1133 corresponding to the first connecting hole 1123, and the first connecting hole 1123 and the second connecting through hole 1133 are correspondingly arranged, which means that the first connecting plate 1122 and the second connecting plate 1132 can sequentially penetrate through the first connecting hole 1123 and the second connecting through hole 1133 through a fastener such as a bolt, so as to achieve fastening connection. The first connecting through-hole 1123 and the second connecting through-hole 1133 are correspondingly arranged in such a manner that, for example, the heights in the axial direction of the holding cavity are the same. The above-mentioned setting mode is convenient to fasten the first connecting plate 1122 and the second connecting plate 1132 by fasteners, so that the connection is convenient and stable. When the first arc plate 1121 and the second arc plate 1131 are used for clamping welding guns 200 with different diameters, the distance between the free end of the first clamping member 112 and the free end of the second clamping member 113 changes, and the fastening connection mode is realized through the fastening piece, so that the fastening pieces with different axial lengths can be conveniently replaced for connection when clamping welding guns 200 with different diameters, and the welding gun clamping mechanism 110 can stably clamp welding guns 200 with different diameters.
The welding gun holding mechanism 110 provided by the embodiment of the present application may be directly fixedly connected to the mounting frame 120, and used as a fixed connection. Or may be rotatably coupled to the mounting bracket 120 by a power mechanism for swing welding.
Illustratively, the welding device 100 further includes a rotary drive assembly 130, and the rotary drive assembly 130 includes, for example, a swing motor provided with a speed reducer. The rotation driving assembly 130 is disposed on the mounting frame 120, and a power output shaft of the rotation driving assembly 130 is connected to the mounting plate 111. The rotation of the mounting plate 111 by the rotary drive assembly 130 to swing the welding gun 200 clamped to the welding gun clamping mechanism 110 requires that the axis of rotation of the power output shaft of the rotary drive assembly 130 and the axis of the clamping cavity be arranged non-collinearly, for example, in a parallel or intersecting manner, wherein the angle between the axis of rotation of the power output shaft of the rotary drive assembly 130 and the axis of the clamping cavity is, for example, 70-110 °, or 80-100 °.
Optionally, the rotational axis of the power output shaft of the rotational drive assembly 130 is perpendicular to the axis of the clamping cavity. This setting makes the welder 200 of centre gripping in welder fixture 110 under the drive of rotation drive assembly 130, swings in the plane of the axis of rotation of the power output shaft of perpendicular to rotation drive assembly 130, can effectively avoid the swing in-process to take place to interfere with mounting bracket 120, and the swing welding is more convenient.
Further, the rotation driving assembly 130 and the welding gun clamping mechanism 110 are respectively disposed at two opposite sides of the mounting frame 120, and a power output shaft of the rotation driving assembly 130 rotatably penetrates through the mounting frame 120 and is connected to the mounting plate 111. In some embodiments, the power output shaft of the rotary drive assembly 130 is positioned radially by a spigot that opens through the mounting bracket 120, the power output shaft of the rotary drive assembly 130 being connected to the mounting plate 111 by a flat key; meanwhile, the mounting plate 111 is further provided with an end positioning plate 1113 engaged with the power output shaft of the rotation driving assembly 130, for axially fixing the power output shaft of the rotation driving assembly 130. The rotation driving assembly 130 and the welding gun clamping mechanism 110 are respectively arranged on two opposite sides of the mounting frame 120, so that interference between the rotation driving assembly and the welding gun clamping mechanism is avoided, and the installation is convenient and the use is stable and reliable.
Referring to fig. 5, in a case where the rotation driving assembly 130 is provided to drive the mounting plate 111 to perform the swing welding, for example, when the mounting plate is configured as a swing motor, the mounting plate 111 has a first rotation dead point and a second rotation dead point under the power of the rotation driving assembly 130, and when the mounting plate 111 rotates to the first rotation dead point, the mounting plate 111 reversely rotates to the second rotation dead point, and then reversely rotates to the first rotation dead point after the mounting plate 111 rotates to the second rotation dead point, so that the mounting plate 111 repeatedly rotates to perform the swing welding.
In some alternative embodiments, the side of the mounting bracket 120 where the welding gun clamping mechanism 110 is disposed is provided with a first stopper 121 and a second stopper 122, and the first stopper 121 and the second stopper 122 may be disposed symmetrically along the rotation axis of the mounting plate 111 that moves under the driving action of the rotation driving assembly 130, for example. When the mounting plate 111 is located at the first rotation stop point, the first limit block 121 abuts against the mounting plate 111 and prevents the mounting plate 111 from continuing to rotate; when the mounting plate 111 is located at the second rotation dead point, the second stopper 122 abuts against the mounting plate 111 and prevents it from continuing to rotate. Through the interference effect of first stopper 121 and second stopper 122 for mounting panel 111 rotates between first rotation stop and second rotation stop, thereby guarantees that welder 200 swings in certain angle, makes the swing welding more accurate, stable, can satisfy the welded requirement of swing better.
The shapes and structures of the first stopper 121 and the second stopper 122 are not particularly limited, as long as the first stopper 121 can interfere with the mounting plate 111 when the mounting plate 111 rotates to the first rotation dead point, and the second stopper 122 can interfere with the mounting plate 111 when the mounting plate 111 rotates to the second rotation dead point. In other embodiments, a limit block may be further provided to interfere with the first clamping plate, the second clamping plate, the welding gun 200, or the like, so as to limit the swing angle.
Illustratively, the side of the first stopper 121 facing the mounting plate 111 has a first stopper surface 1211, the side of the second stopper 122 facing the mounting plate 111 has a second stopper surface 1221, and the mounting plate 111 has a first engagement surface 1114 corresponding to the first stopper surface 1211 and a second engagement surface 1115 corresponding to the second stopper surface 1221. The first stop surface 1211 can abut against the first engagement surface 1114 when the mounting plate 111 rotates to a first rotation dead center, and the second stop surface 1221 can abut against the second engagement surface 1115 when the mounting plate 111 rotates to a second rotation dead center. This setting mode realizes spacingly with face and face laminating's mode, and spacing reliability is higher.
The welding device 100 and the welding gun clamping mechanism 110 provided by the embodiment of the application work according to the following principle:
the first arc plate 1121 and the second arc plate 1131 enclose a clamping cavity for clamping the welding gun 200, and the free end of the first clamping member 112 is detachably connected with the free end of the second clamping member 113, so that the clamping cavity can be opened or closed. When the clamping and fixing of the welding gun 200 is required, the connection between the free end of the first clamping member 112 and the free end of the second clamping member 113 is released, and the clamping chamber is opened. Because at least one of the first clamping member 112 and the second clamping member 113 is rotatably connected with the mounting plate 111, the distance between the free end of the first clamping member 112 and the free end of the second clamping member 113 is increased by rotating the clamping members around the mounting plate 111, so that the opening between the free end of the first clamping member 112 and the free end of the second clamping member 113 is opened, the welding gun 200 can be smoothly placed into the clamping cavity, and then the clamping members are rotated again around the mounting plate 111 to reduce the distance between the first clamping member 112 and the second clamping member 113, so that the first arc-shaped plate 1121 and the second arc-shaped plate 1131 respectively abut against two opposite side walls of the welding gun 200 to be clamped and fixed. The first clamping member 112 and the second clamping member 113 are respectively connected with the mounting plate 111, so that the clamping members and the mounting plate 111 are in an integrated structure to avoid component loss. The installation of the welding gun 200 is realized by opening the clamping cavity by rotating the clamping piece, the clamping and fixing operation of the welding gun 200 is convenient, and the first clamping piece 112 and the second clamping piece 113 are not easy to deform in the process of putting and clamping the welding gun 200, so that the welding gun 200 can be firmly clamped and fixed for a long time.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
