Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a welding clamp unit of a steel wire mesh welding equipment. Background Technology

[0002] As is well known, fire-resistant fireproof panels are a common building material. They are made of specific fire-resistant materials and constructed into a panel structure. These panels are then used to build a wall, serving both as a building facade and as a fire-resistant barrier to prevent the spread of fire. However, these fire-resistant materials themselves lack rigidity. Therefore, to use them as firewalls in buildings, steel wire mesh frames are laid on both ends of the fire-resistant fireproof panel, with steel needles inserted. The two wire mesh frames are then welded together to firmly clamp the fire-resistant fireproof panel, using the rigidity of the wire mesh frames to compensate for the insufficient rigidity of the fire-resistant material.

[0003] Currently, to efficiently weld wire mesh frames, welding equipment is used to align and weld the steel needles after insertion. During welding, a welding clamp unit is used to weld the needles and the wire mesh frame together. Most metal welding currently used is electric welding, which uses electrical energy to heat and fuse the components together. However, for wire mesh frame welding equipment, because the needles are only inserted laterally and the fit between the needles and the wire mesh frame is not very tight, there is a need to develop a welding clamp unit that is both conductive and can quickly clamp the two together. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a welding clamp unit for a wire mesh welding equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A welding clamp unit of a wire mesh welding equipment includes a cylinder, two clamping arms, and a base for fixed installation on the wire mesh welding equipment. The cylinder is fixedly installed on the base. The outer end faces of the middle parts of the two clamping arms are axially connected to the base. The two clamping arms are arranged opposite to each other. A welding head is provided at the clamping jaw at one end of each clamping arm and is located outside the base. A connecting piece is hinged to the other end of each clamping arm. The other end of the connecting piece is hinged to the push rod of the cylinder.

[0007] Preferably, the base has an inner cavity, the cylinder is fixedly installed in the inner cavity, and the welding head protrudes from the inner cavity.

[0008] Preferably, it includes two sleeves, the two ends of which are axially connected to the base, allowing the sleeves to rotate relative to the base, and the outer end face of the middle part of each clamping arm is welded to the corresponding sleeve.

[0009] Preferably, the base is provided with mounting holes for fasteners, and the sleeve is a hollow tube.

[0010] Because of the above solution, this utility model can be fixedly installed on a wire mesh welding equipment. By relying on the push of a single cylinder and the hinge transmission of the connecting plate, the opening and closing of the clamping arm can be realized to achieve the pressing between the steel needle and the wire mesh. With the welding head directly set at the clamping mouth of the clamping arm, welding can be completed simultaneously during clamping. Attached Figure Description

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0014] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. They can refer to a mechanical connection or an electrical connection. They can refer to a direct connection or an indirect connection through an intermediate medium, and they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0016] like Figure 1 and Figure 2 As shown in the figure, the welding clamp unit of the wire mesh welding equipment provided in this embodiment includes a cylinder 1, two clamping arms 2, and a base 3 for fixed installation on the wire mesh welding equipment. The cylinder 1 is fixedly installed on the base 3. The outer end faces of the middle parts of the two clamping arms 2 are axially connected to the base 3. The two clamping arms 2 are arranged opposite to each other. A welding head 4 is provided at the clamping jaw of one end of the clamping arm 2 and is placed outside the base 3. A connecting piece 5 is hinged to the other end of the clamping arm 2. The other end of the connecting piece 5 is hinged to the push rod of the cylinder 1.

[0017] This embodiment can be fixedly installed on a wire mesh welding equipment, and by relying on the push of a single cylinder 1 and the hinge transmission of the connecting piece 5, the opening and closing of the clamping arm 2 can be realized to achieve the pressing between the steel needle and the wire mesh. By directly setting the welding head 4 at the clamping end of the clamping arm 2, welding can be completed simultaneously during clamping.

[0018] In actual operation, driven by the thrust of cylinder 1, when cylinder 1 pushes forward, the hinge points at both ends of the connecting plate 5 rotate synchronously. The connecting plate 5 gradually shifts from a large angle of inclination to a vertical state, thus gradually opening one end of the clamping arm 2 connected to the connecting plate 5. Meanwhile, the other end of the clamping arm 2, relying on the lever principle, is pressed down, and the welding heads 4 of the two clamping arms 2 press against each other, thus satisfying the pressing effect between the steel needle and the wire mesh frame. When the welding heads 4 are energized, the welding is completed. Similarly, when cylinder 1 retracts, the connecting plate 5, initially in a vertical state, gradually becomes inclined, closing one end of the clamping arm 2, while the other end of the clamping arm 2 opens. This opening and closing action completes the welding between the steel needle and the wire mesh frame.

[0019] Furthermore, in order to further reduce the volume, the base 3 in this embodiment is provided with an inner cavity 6, the cylinder 1 is fixedly installed in the inner cavity, and the welding head 4 protrudes out of the inner cavity. This not only allows for a small volume design, but also effectively isolates the external environment from the transmission components, achieving a protective effect.

[0020] Furthermore, to better install the base onto the wire mesh welding equipment, this embodiment designs the shaft connection of the clamping arms 2. Specifically, this embodiment also includes two sleeves 7, the two ends of which are shaft-connected to the base, allowing the sleeves 7 to rotate relative to the base 3. The outer end face of the middle part of each clamping arm 2 is welded integrally with the corresponding sleeve 7. The base 3 is provided with mounting holes 8 for fasteners, and the sleeves 7 are hollow tubes. Thus, one end of the base 3 can be fixed by fasteners, such as bolts, passing through the mounting holes 8, while the other end of the base 3 can also be installed by bolts passing through the sleeves 7, without affecting the shaft connection of the clamping arms 2.

[0021] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
