Description

Technical Field

[0001] This utility model relates to the field of steel bar processing machinery technology, and in particular to a steel bar positioning mechanism and a wire mesh welding device. Background Technology

[0002] In the production of precast components, a large number of steel meshes are typically required. Common steel mesh welding equipment generally involves the intermittent movement of longitudinal steel bars, while a feeding mechanism delivers transverse steel bars to the welding position. The welding components then weld the transverse steel bars to the longitudinal steel bars, and this process is repeated. Currently, steel mesh welding equipment generally uses magnets to attract and position the transverse steel bars that fall from the feeding mechanism. However, when the steel bars fall far from the magnet, have a large diameter, or are heavy, the high temperature of the welding mechanism can cause the magnet to demagnetize, or after prolonged use, the magnet may accumulate a lot of debris or other foreign matter, reducing its attractive force on the steel bars. This can lead to unreliable attraction and ultimately result in incomplete or missing welds in the steel mesh. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a rebar positioning mechanism that is simple in structure, reliable, and conducive to accurate positioning.

[0004] This utility model further provides a wire mesh welding device containing the above-mentioned rebar positioning mechanism. To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A rebar positioning mechanism includes a positioning block, a mounting base, a lever for moving the rebar to the positioning block, and a drive assembly for driving the lever to rotate. The lever is rotatably connected to the mounting base, and the drive assembly is disposed on the mounting base.

[0005] As a further improvement to the above technical solution: the driving assembly includes a swing arm and a driving member for driving the swing arm to swing, one end of the swing arm abuts against one end of the lever, and the other end of the swing arm is connected to the driving member.

[0006] As a further improvement to the above technical solution: the driving component is a telescopic driving component, one end of which is hinged to the swing arm, and the other end of which is hinged to the mounting base.

[0007] As a further improvement to the above technical solution: the telescopic drive component is a cylinder, a hydraulic cylinder, or an electric push rod.

[0008] As a further improvement to the above technical solution: a buffer pad is provided between the swing arm and the lever.

[0009] As a further improvement to the above technical solution: the outer arc arm of the swing arm.

[0010] As a further improvement to the above technical solution: the lever has a bent structure.

[0011] A rebar positioning mechanism includes a mounting base, a lever, and a driving assembly for driving the lever to rotate. The lever is rotatably connected to the mounting base, and a positioning stop is provided on the lever. The driving assembly is disposed on the mounting base.

[0012] A wire mesh welding device includes a feeding mechanism and a lifting welding mechanism, and also includes the aforementioned rebar positioning mechanism. The discharge side of the feeding mechanism is arranged toward the positioning block, and the welding mechanism is located above the positioning block.

[0013] Compared with the prior art, the advantages of this utility model are: The rebar positioning mechanism disclosed in this utility model allows the lever to rotate upwards to an inclined state. After the rebar falls onto the lever, it rolls along the inclined lever under the action of gravity until it contacts the positioning block, ensuring that each falling rebar rolls to the same position. Alternatively, if the rebar does not fall to the target position, the drive assembly drives the lever to rotate, using the lever to move the rebar until it contacts the positioning block, also ensuring that each falling rebar moves to the same position. The structure is simple, reliable, and conducive to accurate positioning. The drive assembly can be set at a position away from the welding mechanism, unaffected by factors such as the diameter and weight of the rebar, the high temperature of the welding mechanism, and slag.

[0014] The wire mesh welding equipment disclosed in this embodiment includes the above-mentioned rebar positioning mechanism, and therefore also has the above-mentioned advantages.

[0015] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0022] In the description of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and 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. Therefore, they should not be construed as limitations on this utility model.

[0023] 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 technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0024] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1 Figures 1 to 5 An embodiment of the rebar positioning mechanism of this utility model is shown. The rebar positioning mechanism of this embodiment includes a positioning block 1, a mounting base 2, a lever 3 for moving the rebar to the positioning block 1, and a driving assembly 4 for driving the lever 3 to rotate. The lever 3 is rotatably connected to the mounting base 2, and the driving assembly 4 is disposed on the mounting base 2.

[0027] See details Figure 2 and Figure 3 In this embodiment, the rebar positioning mechanism has a lever 3 that can rotate upwards to an inclined state. After the transverse rebar 82 falls onto the lever 3, it rolls along the inclined lever 3 under the influence of gravity until it contacts the positioning stop 1, ensuring that each falling transverse rebar 82 rolls to the same position. Then, the lever 3 rotates downwards to disengage from the transverse rebar 82, preventing interference with the welding mechanism 7's welding of the transverse rebar 82 and the longitudinal rebar 81. After the welding mechanism 7 completes the welding, the lever 3 rotates upwards again, and this cycle repeats. See details below. Figure 4 and Figure 5 Alternatively, when the transverse reinforcing bar 82 has not fallen to the target position (located on the longitudinal reinforcing bar 81 and spaced from the positioning block 1), the drive assembly 4 drives the lever 3 to rotate upwards. The lever 3 then moves the transverse reinforcing bar 82 until it contacts the positioning block 1. This ensures that each falling transverse reinforcing bar 82 moves to the same position. The structure is simple, reliable, and conducive to accurate positioning. The drive assembly 4 can be positioned away from the welding mechanism 7, unaffected by the diameter, weight, or falling position of the transverse reinforcing bar 82, or by the high temperature and debris of the welding mechanism 7. Then, the lever 3 rotates downwards, disengaging from the transverse reinforcing bar 82 to avoid interfering with the welding mechanism 7's welding of the transverse and longitudinal reinforcing bars 82 and 81. After the welding mechanism 7 completes welding, the next transverse reinforcing bar 82 falls onto the longitudinal reinforcing bar 81, and the lever 3 rotates upwards again, thus completing the cycle.

[0028] Furthermore, in this embodiment, the drive assembly 4 includes a swing arm 41 and a drive member 42 for driving the swing arm 41 to swing. One end of the swing arm 41 abuts against one end of the lever 3, and the other end of the swing arm 41 is connected to the drive member 42. During operation, the drive member 42 drives the swing arm 41 to swing. When the swing arm 41 swings counterclockwise, it can push the lever 3 to rotate counterclockwise, and the right end of the lever 3 rotates upward. Conversely, when the swing arm 41 swings clockwise, the lever 3 rotates clockwise under its own gravity, and the right end of the lever 3 rotates downward, disengaging from the transverse steel bar 82. The structure is simple and has good reliability.

[0029] In a preferred embodiment, the drive component 42 is a telescopic drive component. One end of the telescopic drive component is hinged to the swing arm 41, and the other end of the telescopic drive component is hinged to the mounting base 2. The swing arm 41 can be driven to swing by the extension and retraction of the telescopic drive component. The structure is simple and has good reliability.

[0030] The telescopic drive component can be, for example, a cylinder, a hydraulic cylinder, or an electric push rod, which will not be described in detail here.

[0031] In a preferred embodiment, a buffer pad 5 (e.g., a rubber pad) is provided between the swing arm 41 and the lever 3. The buffer pad 5 can reduce the impact transmitted from the lever 3 to the swing arm 41 and the drive member 42, and reduce the noise during operation of the device.

[0032] As a preferred embodiment, the outer arc-shaped arm of the swing arm 41 helps to increase the contact area with the lever 3, while making the device operate more smoothly.

[0033] As a preferred embodiment, the lever 3 has a bent structure, which helps to avoid other parts on the mesh welding equipment and makes the device operate more smoothly.

[0034] Example 2 Figure 6 Another embodiment of the rebar positioning mechanism of this utility model is shown. The rebar positioning mechanism of this embodiment is basically similar to that of embodiment one, except that: A rebar positioning mechanism includes a mounting base 2, a lever 3, and a driving assembly 4 for driving the lever 3 to rotate. The lever 3 is rotatably connected to the mounting base 2. The lever 3 is provided with a positioning stop 31. The driving assembly 4 is located on the mounting base 2, that is, the positioning function is integrated on the lever 3, and there is no need to set the positioning stop 1 in Embodiment 1.

[0035] In this embodiment of the rebar positioning mechanism, the lever 3 can be rotated upwards to an inclined state. After the transverse rebar 82 falls onto the lever 3, it rolls along the inclined lever 3 under the action of gravity until it contacts the positioning stop 31, ensuring that each falling transverse rebar 82 rolls to the same position. Then the lever 3 rotates downwards to disengage from the transverse rebar 82, avoiding interference with the welding mechanism 7 in welding the transverse rebar 82 and the longitudinal rebar 81. After the welding mechanism 7 completes the welding, the lever 3 rotates upwards again, and the cycle repeats.

[0036] Example 3 The mesh welding equipment of this embodiment includes a feeding mechanism 6 and a lifting welding mechanism 7, as well as the above-mentioned rebar positioning mechanism. The discharge side of the feeding mechanism 6 is arranged toward the positioning block 1, and the welding mechanism 7 is located above the positioning block 1.

[0037] See details Figure 2 and Figure 3In this embodiment of the mesh welding equipment, the lever 3 can be rotated upwards to an inclined state. After the transverse steel bar 82 in the feeding mechanism 6 falls onto the lever 3, it rolls along the inclined lever 3 under the action of gravity until it contacts the positioning stop 1, ensuring that each falling transverse steel bar 82 rolls to the same position. Then the lever 3 rotates downwards to disengage from the transverse steel bar 82, avoiding interference with the welding mechanism 7 in welding the transverse steel bar 82 and the longitudinal steel bar 81. After the welding mechanism 7 descends to complete the welding of the longitudinal steel bar 81 and the transverse steel bar 82, the lever 3 rotates upwards again, and this cycle repeats. See details. Figure 4 and Figure 5 Alternatively, when the transverse steel bar 82 in the feeding mechanism 6 has not fallen to the target position (located on the longitudinal steel bar 81 and spaced from the positioning block 1), the drive assembly 4 drives the lever 3 to rotate upward. The lever 3 moves the transverse steel bar 82 until it contacts the positioning block 1. This ensures that each falling transverse steel bar 82 can move to the same position. The structure is simple, reliable, and conducive to accurate positioning. Then, the lever 3 rotates downward to disengage from the transverse steel bar 82, avoiding interference with the welding mechanism 7's welding of the transverse steel bar 82 and the longitudinal steel bar 81. After the welding mechanism 7 descends to complete the welding of the longitudinal steel bar 81 and the transverse steel bar 82, the longitudinal steel bar 81 moves forward the target distance, and the next transverse steel bar 7 in the feeding mechanism 6 falls onto the longitudinal steel bar 81. The lever 3 then rotates upward again, and the cycle repeats.

[0038] The mesh welding equipment of this embodiment includes the above-mentioned rebar positioning mechanism, and therefore also has the above-mentioned advantages.

[0039] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
