Description

Technical Field

[0001] The invention relates to the technical field of metal welding, and in particular to a wire clamping device. Background Art

[0002] In the process of processing metal components, it is often necessary to weld the ends of two metal wires to form an integral structure. Existing metal welding often uses cold welding technology. When a cold welding machine welds metal parts, a clamping device is required to clamp the metal parts to be welded so that the cold welding machine can weld the metal parts.

[0003] Existing clamping devices all require the use of molds of corresponding sizes according to the specifications of the wires being connected. When wires of different specifications need to be connected, the corresponding molds must be replaced, which not only increases the mold cost, but also reduces the welding efficiency when the molds are disassembled and assembled. Summary of the invention

[0004] The object of the present invention is to provide a wire clamping device for reducing costs and improving wire welding efficiency.

[0005] In order to achieve the above-mentioned purpose, the present invention provides a wire clamping device, including a first support frame, a first pressing member and a second pressing member, the first pressing member is fixedly arranged on the first support frame, and the second pressing member moves in a first direction close to or away from the first pressing member, so as to make the first pressing member and the second pressing member press into contact or out of contact.

[0006] When the above technical solution is adopted, when the first pressing member and the second pressing member are out of contact, the wire can be placed between the first pressing member and the second pressing member, and then the second pressing member is controlled to move in the first direction close to the first pressing member, and the first pressing member and the second pressing member are pressed and contacted, so as to clamp the wire. Compared with the prior art that requires the replacement of molds corresponding to wires of different specifications and sizes, the wire clamping device provided by the present invention can control the spacing and pressing force when the first pressing member and the second pressing member are pressed and contacted when clamping wires of different specifications and sizes, without the need to replace the mold, thereby expanding the scope of application, not only reducing costs, but also avoiding the situation where the wire clamping efficiency is low due to the need to replace the mold and disassemble and assemble the mold, and further improving the wire welding efficiency.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it 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. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] See also Figure 1 As shown, an embodiment of the present invention provides a wire clamping device, including a first support frame 1, a first pressing member 2 and a second pressing member 3, the first pressing member 2 is fixedly arranged on the first support frame 1, and the second pressing member 3 moves in a first direction close to or away from the first pressing member 2, so as to make the first pressing member 2 and the second pressing member 3 press into contact or out of contact.

[0022] When the above technical solution is adopted, when the first pressing member 2 and the second pressing member 3 are out of contact, the wire can be placed between the first pressing member 2 and the second pressing member 3, and then the second pressing member 3 is controlled to move in the first direction close to the first pressing member 2, and the first pressing member 2 and the second pressing member 3 are pressed and contacted, so as to clamp the wire. Compared with the situation in the prior art where the mold needs to be replaced corresponding to wires of different specifications and sizes, the wire clamping device provided in the embodiment of the present invention can control the spacing and pressing force when the first pressing member 2 and the second pressing member 3 are pressed and contacted when clamping wires of different specifications and sizes, without the need to replace the mold operation, thereby expanding the scope of application, not only reducing costs, but also avoiding the situation where the wire clamping efficiency is low due to the need to replace the mold and disassemble and assemble the work, and further improving the wire welding efficiency.

[0023] In specific implementation, the wire can be a rectangular copper wire or a rectangular aluminum wire. The wire clamping device provided by the embodiment of the present invention can adapt to rectangular copper wires or rectangular aluminum wires of different specifications, avoiding the situation where the existing wire clamping device needs to replace the corresponding mold when clamping wires of different specifications. Specifically, the first direction can be a vertical direction, and accordingly, the first pressing member 2 and the second pressing member 3 can be used to press and contact the upper and lower surfaces of the wire respectively.

[0024] In one possible implementation, Figure 1 As shown, the wire clamping device provided in the embodiment of the present invention further includes a second support frame 4 and a first driving mechanism 5. The second support frame 4 is slidably arranged on the first support frame 1 along the second direction, and the first direction is perpendicular to the second direction. The second support frame 4 is provided with a receiving groove for accommodating the second pressing member 3, and the second pressing member 3 is slidably arranged on the second support frame 4 in the first direction. The setting of the receiving groove ensures that the second pressing member 3 moves closer to or away from the first pressing member 2 in the first direction, thereby avoiding the second pressing member 3 from being offset during movement.

[0025] The first driving mechanism 5 is arranged on the second support frame 4, and the second pressing member 3 is arranged at the driving end of the first driving mechanism 5. The first driving mechanism 5 is used to drive the second pressing member 3 to reciprocate in the first direction. In this way, the first driving mechanism 5 is used to realize the method of clamping the wire material in the first direction by the first pressing member 2 and the second pressing member 3. Different pressures can be automatically selected to clamp the wire material according to wire materials of different specifications, thereby avoiding the problem of crushing the wire material due to excessive clamping force and slipping due to insufficient clamping force, and effectively improving the yield rate and efficiency of wire docking.

[0026] As an alternative, see Figures 1 to 3 As shown, the side of the second pressing member 3 away from the first pressing member 2 is a first inclined surface 31, and there is an acute angle between the first inclined surface 31 and the second direction. The first driving mechanism 5 includes a first driving cylinder 51 and a wedge block 52. The cylinder body of the first driving cylinder 51 is arranged on the second support frame 4, and the wedge block 52 is arranged on the driving end of the first driving cylinder 51. The first driving cylinder 51 is used to drive the wedge block 52 to reciprocate in the second direction. The wedge block 52 has a second inclined surface 521 that matches the first inclined surface 31. In actual situations, the first inclined surface 31 can be inclined upward along the first direction. Of course, the first inclined surface 31 can also be inclined downward along the first direction, which is not specifically limited here. When the driving end of the first driving mechanism 5 is extended or retracted, the wedge block 52 is driven to reciprocate in the second direction. Due to the arrangement of the accommodating groove for accommodating the second pressing member 3 provided on the second supporting frame 4, the second pressing member 3 is forced to reciprocate in the first direction, thereby causing the second pressing member 3 to move closer to or away from the first pressing member 2 in the first direction, thereby achieving pressing contact or disengagement between the first pressing member 2 and the second pressing member 3.

[0027] In some embodiments, the first inclined surface 31 is provided with one of the protrusion 522 and the recess 32 that cooperate with each other, and the second inclined surface 521 is provided with the other of the protrusion 522 and the recess 32. The arrangement of the protrusion 522 and the recess 32 is used to improve the stability of the mutual cooperation between the wedge block 52 and the second pressing member 3, and avoid the situation where the wedge block 52 and the second pressing member 3 are separated or misaligned. In specific implementation, refer to Figure 2 and Figure 3 As shown, a recessed portion 32 is provided on the first inclined surface 31 of the second pressing member 3, and a protrusion 522 is provided on the wedge block 52. Of course, in a specific implementation, a protrusion 522 may also be provided on the second pressing member 3, and a recessed portion 32 may be provided on the wedge block 52. No specific limitation is made here, and the actual situation shall prevail.

[0028] In a specific implementation, the protrusion 522 can be a rectangular protrusion or a trapezoidal protrusion, etc. In an example, see Figure 2 and Figure 3 As shown, the protrusion is a T-shaped protrusion, and correspondingly, the recess 32 is a T-shaped recess.

[0029] As a possible implementation, the wire clamping device provided in the embodiment of the present invention further includes a third pressing member 7 and a fourth pressing member 8, wherein the third pressing member 7 is slidably disposed on the first support frame 1 along the first direction, and the fourth pressing member 8 is fixedly disposed on the second support frame 4, and is used for pressing and contacting with the third pressing member 7. In this way, when the first direction is a vertical direction, the second direction can be a horizontal direction, the first pressing member 2 and the second pressing member 3 are used to clamp the upper and lower surfaces of the wire, and the third pressing member 7 and the fourth pressing member 8 are used to clamp the left and right surfaces of the wire. In this way, pressing members are disposed all around the wire, and the wire is clamped from two directions, thereby improving the stability of the wire clamping and avoiding the phenomenon of wire dislocation and retreat when the two wires are butt-welded.

[0030] In a possible implementation, the wire clamping device provided by the embodiment of the present invention further includes a second driving mechanism 6, which is arranged on the first support frame 1, and the second support frame 4 is arranged at the driving end of the second driving mechanism 6, and the second driving mechanism 6 is used to drive the second support frame 4 to slide relative to the first support frame 1 in the second direction. Since the third pressing member 7 is slidably arranged on the first support frame 1 along the first direction, and the fourth pressing member 8 is fixedly arranged on the second support frame 4, when the second driving mechanism 6 drives the second support frame 4 to slide relative to the first support frame 1 in the second direction, the fourth pressing member 8 is synchronously driven to move in a direction close to or away from the third pressing member 7, so that the fourth pressing member 8 is squeezed into contact or out of contact with the third pressing member 7. The second driving mechanism 6 is used to realize the method of clamping the wire in the second direction by the third pressing member 7 and the fourth pressing member 8, and different pressures can be automatically selected according to wires of different specifications for clamping the wires, thereby avoiding the problem of crushing the wires due to excessive clamping force and slipping due to insufficient clamping force, and effectively improving the yield and efficiency of wire docking.

[0031] In some embodiments, the wire clamping device provided by the embodiments of the present invention also includes an elastic member, and the two ends of the elastic member elastically act on the first support frame 1 and the third pressing member 7 respectively, for applying a force to the third pressing member 7 close to the second pressing member 3, so as to ensure that when the first pressing member 2 and the second pressing member 3 are out of contact, the third pressing member 7 can pop out, so as to ensure that the third pressing member 7 can be squeezed into contact with the fourth pressing member 8.

[0032] In some embodiments, a sliding groove 11 corresponding to the third pressing member 7 is formed on the first support frame 1, and the opening of the sliding groove 11 faces the second pressing member 3. A limiting hole 12 is also formed on the first support frame 1, and the limiting hole 12 is connected to the sliding groove 11, and the limiting hole 12 extends along the first direction. Figure 4 The wire clamping device provided in the embodiment of the present invention also includes a limit pin 9, one end of which is connected to the third pressing piece 7, and the other end of the limit pin 9 extends into the limit hole 12, which is used to form a gap between the third pressing piece 7 and the second pressing piece 3 for the wire to pass through, so as to facilitate the placement of the wire between the first pressing piece 2, the second pressing piece 3, the third pressing piece 7 and the fourth pressing piece 8 from the gap.

[0033] In an optional embodiment, the second driving mechanism 6 includes a second driving cylinder, the cylinder body of the second driving cylinder is arranged on the first support frame 1, and the second support frame 4 is arranged at the driving end of the second driving cylinder. The setting of the second driving cylinder facilitates the reciprocating movement of the second support frame 4 relative to the first support frame 1 along the second direction.

[0034] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.
