Description

Technical Field

[0001] This application belongs to the field of agricultural machinery, specifically relating to a positioner and a welding workstation. Background Technology

[0002] like Figure 1 As shown, the welding workstation mainly includes a welding device W and a positioning device M. The workpiece P is loaded onto the loading platform of the positioning device M by the operator, and the positioning device M adjusts the posture of the workpiece P relative to the welding device W to facilitate welding.

[0003] However, in the existing welding workstation, the welding device W is idle while the operator loads the material; it only starts working after the operator finishes loading and welding is completed. After welding, the operator loads the material again, at which point the welding device W is idle once more. This represents a significant waste of time and resources and urgently needs optimization.

[0004] If multiple loading platforms are installed on the existing displacement device M to perform loading and welding work simultaneously, the floor space required for the displacement device M to operate will be greatly increased. Utility Model Content

[0005] The purpose of this application is to provide a positioner and a welding workstation to improve the working efficiency of the welding workstation and reduce the floor space occupied by the welding workstation.

[0006] To achieve the above objectives, this application provides a positioner, which includes:

[0007] Columns;

[0008] The slewing arm includes a slewing arm pivot connected to the top of the column and slewing arm mounting parts at both ends;

[0009] The slewing arm drive unit is used to drive the pivot part of the slewing arm to rotate around the horizontal arm rotation axis;

[0010] Several mounting platforms are pivotally mounted on the slewing arm mounting section.

[0011] In some implementations, the positioner includes:

[0012] The displacement drive unit is located in the slewing arm mounting section and is used to drive the mounting platform to rotate around the horizontal platform rotation axis.

[0013] In some embodiments, the slewing arm mounting portion includes a first slewing arm mounting portion and a second slewing arm mounting portion located at both ends of the slewing arm. The first slewing arm mounting portion rotates about a horizontal first platform rotation axis, and the second slewing arm mounting portion rotates about a horizontal second platform rotation axis. The first platform rotation axis and the second platform rotation axis are symmetrically arranged on both sides of the arm rotation axis.

[0014] In some implementations, the positioner includes:

[0015] An arc-blocking plate extends from the slewing arm mounting section and is used to separate the first mounting platform mounted on the first slewing arm mounting section from the second mounting platform mounted on the second slewing arm mounting section.

[0016] In some embodiments, the bottom end of the column is provided with a detachable base, and the periphery of the detachable base is provided with mounting screw holes.

[0017] In some implementations, the installation platform includes:

[0018] Platform board;

[0019] Several strip-shaped support blocks are arranged sequentially and at intervals on the mounting plate surface of the platform plate;

[0020] Several clamps are used to press the workpiece against the strip support block. The clamps are set at the edge of the platform plate and extend toward the strip support block.

[0021] In some embodiments, the platform plate has a plurality of discretely arranged positioning holes and positioning pins that are detachably mounted on the positioning holes. The positioning pins are used to align and connect the slots and / or holes on the workpiece.

[0022] This application also protects a welding workstation, which includes the aforementioned positioner.

[0023] In some implementations, the welding workstation includes:

[0024] The welding station is located on the first side of the positioner and is equipped with a welding machine for welding workpieces clamped on the welding installation platform.

[0025] In some implementations, the welding workstation includes:

[0026] The operating station, located on the second side of the positioner, provides operating space for clamping workpieces onto the mounting platform.

[0027] Through the above technical solutions, the positioner provided in this application embodiment has the following beneficial effects:

[0028] In the technical solution of this application, the rotary arm drive unit can drive the rotary arm to pivot relative to its horizontal arm rotation axis, and simultaneously change the position of multiple mounting platforms. Compared with the prior art, where the welding device is idle when the operator loads materials, and can only start working after the operator finishes loading, the positioner in this application allows loading and welding operations to be performed simultaneously. That is, while the workpiece on the mounting platform at one end of the rotary arm is being welded, the mounting platform at the other end of the rotary arm can also be loaded with workpieces, and the positioner realizes the feeding of the workpieces, avoiding the idleness of the welding device and greatly improving the production efficiency of the welding workstation. In addition, in order to avoid the positioner requiring too much space when performing rotary feeding, the column supports the rotary arm through the rotary arm pivot, so that the rotary arm is away from the ground and the arm rotation axis is set horizontally. After raising the setting height of the rotary arm and changing the rotation direction of the rotary arm, the positioner can free up operating space for convenient operation by the operator and improve the overall compactness of the welding workstation.

[0046] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0047] The positioner and welding workstation according to this application are described below with reference to the accompanying drawings.

[0048] This application discloses a novel positioner, such as Figure 2 and Figure 4 As shown, in one specific embodiment, the positioner 1 includes:

[0049] Column 11;

[0050] The rotary arm 14 includes a rotary arm pivot A connected to the top of the column 11 and rotary arm mounting parts B at both ends;

[0051] The slewing arm drive unit 12 is used to drive the pivot part A of the slewing arm to rotate around the horizontal arm rotation axis C;

[0052] Several mounting platforms 2 are pivotally mounted on the slewing arm mounting section B.

[0053] See Figure 4 The positioner 1 can change or fix the positions of multiple mounting platforms 2, thereby enabling the switching of the mounting platforms 2 to achieve the feeding action, and allowing operators to perform loading and welding operations simultaneously on different mounting platforms 2. Compared to existing technologies, such as Figure 1As shown, in the previous method, the welding device W was idle when the operator loaded the material, and could only start working after the operator finished loading. The positioner 1 of this application avoids this idleness of the welding device W, greatly improving the production efficiency of the welding workstation. Furthermore, to avoid excessive floor space required for the positioner 1 to perform rotary feeding, the rotary feeding structure (rotary arm 14) can be designed as a space-saving rod structure. For example, the rotary arm 14 rotates horizontally... Figure 1 As shown, the required floor space is relatively large. Therefore, a column 11 is added, which supports the rotary arm 14 through the rotary arm pivot A, so that the rotary arm 14 is away from the ground and the rotation axis C of the arm is set horizontally. This avoids interference between the rotational movement of the rotary arm 14 and the ground, reduces the required floor space, and frees up operating space for operators, thus improving the overall compactness of the welding workstation. In addition, the pivotable mounting of the mounting platform 2 on the rotary arm mounting part B allows the mounting platform 2 to adjust its angle to facilitate subsequent welding operations.

[0054] Of course, those skilled in the art will understand that the technical effect of the positioner 1 in switching the position of the installation platform 2 is not limited to enabling operators to perform loading and welding operations simultaneously on different installation platforms 2, but can also enable simultaneous loading and sheet metal operations, etc.; the number of rotary arms 14 in the positioner 1 is not limited to Figure 2 and Figure 4 The number of rotary arms 14 shown can be one or more to further improve production efficiency. For example, when there are two rotary arms 14, the number of mounting platforms 2 can be four. The rotary arm drive unit 12 can be a combination of a servo motor and a reducer, etc.

[0055] As described above, the mounting platform 2 can adjust its angle to change the placement of the workpiece P, thereby facilitating subsequent welding operations. To further improve the efficiency and accuracy of the angle adjustment of the mounting platform 2, in this embodiment, as follows... Figure 2 and Figure 4 As shown, the positioner 1 may include:

[0056] The displacement drive unit 13 is located at the rotary arm mounting section B and is used to drive the mounting platform 2 to rotate around the horizontal platform rotation axis D. See also... Figure 2 and Figure 4 Thus, the angle of the mounting platform 2 can be adjusted by the displacement drive unit 13 to facilitate loading or welding operations of the workpiece P. Depending on the form of the workpiece P, each displacement drive unit 13 can independently adjust the angle of the mounting platform 2 to facilitate clamping and processing of the workpiece P. The displacement drive unit 13 can be a motor. Those skilled in the art will understand that the angle adjustment of the mounting platform 2 is also achieved manually.

[0057] Depending on the form of the workpiece P and other requirements, the positional relationship between each mounting platform 2 and the arm rotation axis C can be varied. This is to further reduce the floor space required when the rotary arm 14 performs rotary feeding operations. In this embodiment, for example... Figure 2 and Figure 4 As shown, the slewing arm mounting part B may include a first slewing arm mounting part and a second slewing arm mounting part located at both ends of the slewing arm 14. The first slewing arm mounting part rotates around a horizontal first platform rotation axis, and the second slewing arm mounting part rotates around a horizontal second platform rotation axis. The first platform rotation axis and the second platform rotation axis are symmetrically arranged on both sides of the arm rotation axis C.

[0058] See Figure 2 The first platform rotation axis, the second platform rotation axis, and the arm rotation axis C are parallel, and the first platform rotation axis and the second platform rotation axis are arranged symmetrically about the arm rotation axis C. This reduces the space required for the rotation of the rotary arm 14, thereby improving the compactness of the positioner 1 and further reducing its floor space.

[0059] To ensure the safety of operators, such as Figure 2 and Figure 4 As shown, the positioner 1 may include an arc-blocking plate 15, which extends from the rotary arm mounting portion B and serves to separate the first mounting platform mounted on the first rotary arm mounting portion from the second mounting platform mounted on the second rotary arm mounting portion. Thus, when welding operations are performed on the first mounting platform, the arc-blocking plate 15 prevents the clamping operation of the second mounting platform from being affected by the welding arc light, and also keeps the second mounting platform away from potential weld spatter, thereby improving the safety and reliability of the positioner 1.

[0060] In this embodiment, such as Figure 2 and Figure 4 As shown, the bottom end of the column 11 may be provided with a detachable base 11a, and the periphery of the detachable base 11a is provided with mounting screw holes. In this way, the positioner 1 can be flexibly set in the required position through the detachable base 11a.

[0061] In actual production, it is necessary to consider not only workpieces P of various specifications, but also how to install workpieces P of different specifications on the mounting platform 2 while ensuring installation efficiency. In this embodiment, as... Figure 3 As shown, the installation platform 2 may include:

[0062] Platform board 21;

[0063] Several strip-shaped support blocks 22 are arranged sequentially and at intervals on the mounting plate surface of the platform plate 21;

[0064] Several clamps 23 are used to press the workpiece P against the strip support block 22. The clamps 23 are located at the edge of the platform plate 21 and extend toward the strip support block 22.

[0065] Multiple strip-shaped support blocks 22 can be placed between the platform plate 21 and the workpiece P to provide uniform support for the workpiece P. The slots formed by the spaced intervals of the strip-shaped support blocks 22 not only engage with the protrusions of the workpiece P, improving the fixation effect of the workpiece P, but also collect welding slag generated during welding operations, facilitating cleaning. Furthermore, the clamp 23 presses the workpiece P firmly onto the strip-shaped support blocks 22, thereby ensuring the fixation effect of the workpiece P, facilitating subsequent welding or sheet metal operations, and improving the reliability and safety of the positioner 1.

[0066] When the workpiece P has a complex shape, the contact area between the strip support block 22 and the clamp 23 and the workpiece P may be small, and the holding effect may not be ideal. To ensure a stable clamping between the workpiece P and the mounting platform 2 in this embodiment, as follows... Figure 2 As shown, the platform plate 21 may have a plurality of discretely arranged positioning holes and positioning posts 24 detachably mounted on the positioning holes. The positioning posts 24 are used for aligning and connecting the slots and / or holes on the workpiece P. In this way, the flexible arrangement of the positioning posts 24 allows them to be inserted into the slots and / or holes on workpieces P of various sizes, thereby improving the fixation effect of the workpiece P on the mounting platform 2.

[0067] This application discloses a novel welding workstation, such as Figure 4 As shown, a welding workstation in one specific embodiment includes the aforementioned positioner 1. Obviously, this welding workstation also possesses all the technical effects of the aforementioned positioner 1, so they will not be described in detail here.

[0068] In this embodiment, such as Figure 4 As shown, a welding workstation may include:

[0069] The welding station is located on the first side of the positioner 1 and is equipped with a welding machine 3 for welding the workpiece P clamped on the welding mounting platform 2.

[0070] Specifically, see Figure 4 The welding station is positioned adjacent to the rotational space formed by the rotating installation platform 2, allowing the welding machine 3 in the welding station to approach the workpiece P. The welding machine 3 can be a multi-axis rotating robotic arm with a welding torch at its free end, ensuring its versatility for workpieces P of different specifications. Of course, those skilled in the art will understand that welding operations can also be performed manually by an operator at the welding station.

[0071] In this embodiment, such as Figure 4 As shown, a welding workstation may include:

[0072] The operating station, located on the second side of the positioner 1, provides operating space for clamping workpiece P onto the mounting platform 2. (See also...) Figure 4 The operating station is located adjacent to the rotation space formed by the rotation of the installation platform 2, and is located on the side of the rotation space away from the welding station. This not only ensures that the operating station has enough operating space to clamp the workpiece P onto the installation platform 2, but also ensures that the welding workstation is compact as a whole.
