Description

Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to a flexible welding platform. Background Technology

[0002] Currently, during the welding process, the workpiece needs to be placed on a welding platform and then fixed according to the welding requirements. Existing technology typically uses an integrated auxiliary clamping fixture to clamp and fix the workpiece to be welded onto the welding platform. This clamping is done manually and cannot be automated, making the welding process time-consuming, labor-intensive, and inefficient. Furthermore, a single integrated auxiliary clamping fixture cannot adapt to different welding requirements and cannot determine the clamping position based on the different shapes of the workpieces. Utility Model Content

[0003] To address the shortcomings of the prior art, this invention provides a flexible welding platform that improves welding efficiency through automatic control and can adapt to the welding needs of workpieces with different shapes.

[0004] The technical effect to be achieved by this utility model is realized through the following technical solution:

[0005] This utility model provides a flexible welding platform, comprising:

[0006] Platform entity;

[0007] A positioning mechanism is provided on the surface of the platform body. The positioning mechanism includes a plurality of positioning holes arranged in an array, a first fixing hole and a mounting hole. A welding station is formed on the positioning mechanism, and the welding station is used to place the workpiece to be welded.

[0008] A plurality of mechanical fixing mechanisms are provided, each of which is detachably mounted on the platform body at intervals along the outer periphery of the welding station via the first fixing holes, to fix the workpiece to be welded on the platform body; and

[0009] Several magnetic fixing mechanisms are detachably installed in the mounting holes to adsorb the workpiece to be welded onto the platform body.

[0010] In some implementations, the mechanical fixing mechanism includes a clamping assembly and a pushing assembly. The clamping assembly is used to fix the workpiece to be welded from a first direction, and the pushing assembly is used to fix the workpiece to be welded from a second direction, which is perpendicular to the first direction.

[0011] In this implementation, the clamping component can be extended and retracted along the first direction to clamp and fix the workpiece to be welded, and the pushing component can be extended and retracted along the second direction to hold the workpiece to be welded, thereby avoiding the problem of the workpiece to be welded shifting along the second direction on the platform body and ensuring the stability of the welding process.

[0012] In some implementations, the clamping assembly includes a first drive cylinder and a clamping block. The first drive cylinder is detachably mounted on the platform body through the first fixing hole. The first drive cylinder has a first piston rod, which is telescopically connected to the clamping block along a first direction.

[0013] In this implementation, the first driving cylinder drives the first piston rod to extend, causing the clamping block to move away from the platform body. The clamping block is rotated so that it is positioned above the workpiece to be welded. The first driving cylinder then drives the first piston rod to retract so that the clamping block clamps the workpiece to be welded.

[0014] In some implementations, the first drive cylinder has a second fixing hole, and a bolt passes through both the second fixing hole and the first fixing hole to fix the first drive cylinder to the platform body.

[0015] In some implementations, the pushing assembly includes a second drive cylinder and a pushing block. The second drive cylinder is detachably mounted on the platform body through the first fixing hole. The second drive cylinder has a second piston rod that is telescopically arranged in a second direction and connected to the pushing block.

[0016] In this implementation, the second drive cylinder drives the second piston rod to extend so that the flat push block pushes against the side of the workpiece to be welded, thereby preventing the workpiece to be welded from shifting along the second direction on the platform body.

[0017] In some implementations, the second drive cylinder has a third fixing hole, and a bolt passes through both the third fixing hole and the first fixing hole to fix the second drive cylinder to the platform body.

[0018] In some implementations, the flexible welding platform further includes a backing plate connected to the platform body and having a through hole. The mechanical fixing mechanism is connected to the surface of the backing plate opposite to the platform body, and bolts are inserted through both the through hole and the first fixing hole to fix the backing plate to the platform body.

[0019] In some implementations, the first fixing hole is located at the periphery of the positioning hole.

[0020] In some implementations, the inner peripheral wall of the mounting hole extends toward the center of the mounting hole with a recessed platform, and the first fixing hole is also formed on the recessed platform. The magnetic fixing mechanism is detachably installed in the mounting hole and abuts against the recessed platform.

[0021] In this implementation, the stability of the magnetic fixing mechanism when installed in the mounting hole is enhanced.

[0022] In some implementations, the magnetic fixing mechanism includes an annular mounting bracket and an electromagnet. The annular mounting bracket is installed in the mounting hole and abuts against the recessed platform. The electromagnet is installed in the annular mounting bracket. The upper surfaces of the annular mounting bracket and the electromagnet are flush with the upper surface of the platform body. A fourth fixing hole is provided on the upper surface of the annular mounting bracket.

[0023] In summary, this utility model has at least the following advantages:

[0024] The flexible welding platform provided by this utility model has multiple positioning holes, first fixing holes, and mounting holes arranged in an array on the surface of the platform body. Several mechanical fixing mechanisms are detachably installed on the platform body through the first fixing holes, and several magnetic fixing mechanisms are detachably installed in the mounting holes. In this way, the mechanical fixing mechanisms and the magnetic fixing mechanisms can be arranged on the surface of the platform body according to the shape of the workpiece to be welded. When the power source is turned on, the mechanical fixing mechanisms and the magnetic fixing mechanisms fix the workpiece to be welded on the surface of the platform body. The welding efficiency is improved through automatic control, and it can adapt to the welding needs of workpieces with different shapes. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0036] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0037] Example 1:

[0038] Please see the appendix Figure 1 ~Appendix Figure 2 The flexible welding platform of this utility model includes a platform body 100, a positioning mechanism 200, several mechanical fixing mechanisms 300 and several magnetic fixing mechanisms 400.

[0039] In this regard, please combine Figure 1 and Figure 2 , Figure 1 The diagram illustrates the structural relationship between the platform body 100, the positioning mechanism 200, several mechanical fixing mechanisms 300, and several magnetic fixing mechanisms 400 in this embodiment of the present invention. Figure 2The illustration shows the specific structure of the magnetic fixing mechanism 400 in this embodiment of the present invention. Specifically, the positioning mechanism 200 is disposed on the surface of the platform body 100. The positioning mechanism 200 includes a plurality of positioning holes 201 arranged in an array, a first fixing hole 202, and a mounting hole 203. A welding station 101 is formed on the positioning mechanism 200, which is used to place the workpiece 600 to be welded. A plurality of mechanical fixing mechanisms 300 are detachably installed on the platform body 100 at intervals along the outer periphery of the welding station 101 through the first fixing hole 202 to fix the workpiece 600 to be welded on the platform body 100. A plurality of magnetic fixing mechanisms 400 are detachably installed in the mounting hole 203 to attract the workpiece 600 to be welded onto the platform body 100.

[0040] In this embodiment, the positioning mechanism 200 is disposed on the surface of the platform body 100. Specifically, the surface of the platform body 100 has multiple positioning holes 201, first fixing holes 202, and mounting holes 203 arranged in an array. Several mechanical fixing mechanisms 300 are detachably mounted on the platform body 100 through the first fixing holes 202, and several magnetic fixing mechanisms 400 are detachably mounted in the mounting holes 203. Specifically, when welding a workpiece, the workpiece 600 to be welded is placed on the surface of the platform body 100. The workpiece 600 is attracted and fixed to the platform body 100 by the magnetic fixing mechanisms 400. External positioning posts are inserted into the positioning holes 201 to pre-position the workpiece 600, thus forming a welding station 101. Then, several mechanical fixing structures are installed on the outer periphery of the welding station 101 to further fix the workpiece 600, ensuring a stable connection between the workpiece 600 and the platform body 100 and preventing displacement during welding.

[0041] It is understandable that, since both the mechanical fixing mechanisms 300 and the magnetic fixing mechanisms 400 are detachably installed on the surface of the platform body 100, the arrangement of the mechanical fixing mechanisms 300 and the magnetic fixing mechanisms 400 on the platform body 100 can be determined according to the shape of the workpiece 600 to be welded. For example, when the workpiece 600 to be welded is square, the mechanical fixing mechanisms 300 can be arranged in a square shape around the perimeter of the workpiece 600 to be welded, thereby fixing multiple points of the workpiece 600 to be welded. The position and number of the magnetic fixing mechanisms 400 can be selected according to the shape and area of ​​the workpiece 600 to be welded, thereby achieving a better fixing effect.

[0042] The aforementioned flexible welding platform has multiple positioning holes 201, first fixing holes 202, and mounting holes 203 arranged in an array on the surface of the platform body 100. Several mechanical fixing mechanisms 300 are detachably mounted on the platform body 100 through the first fixing holes 202, and several magnetic fixing mechanisms 400 are detachably mounted in the mounting holes 203. In this way, the mechanical fixing mechanisms 300 and the magnetic fixing mechanisms 400 can be arranged on the surface of the platform body 100 according to the shape of the workpiece 600 to be welded. When the power source is turned on, the mechanical fixing mechanisms 300 and the magnetic fixing mechanisms 400 fix the workpiece 600 to be welded on the surface of the platform body 100. The welding efficiency is improved through automatic control, and it can adapt to the welding needs of workpieces with different shapes.

[0043] Example 2:

[0044] The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the flexible welding platform of this utility model. Please refer to the appendix for details. Figure 2 .

[0045] The mechanical fixing mechanism 300 includes a clamping assembly 310 and a pushing assembly 320. The clamping assembly 310 is used to fix the workpiece 600 to be welded from a first direction, and the pushing assembly 320 is used to fix the workpiece 600 to be welded from a second direction, which is perpendicular to the first direction.

[0046] In this embodiment, the clamping component 310 can be extended and retracted along the first direction to clamp and fix the workpiece 600 to be welded, and the pushing component 320 can be extended and retracted along the second direction to hold the workpiece 600 to be welded, thereby avoiding the problem of the workpiece 600 to be welded shifting along the second direction on the platform body 100 and ensuring the stability of the welding process.

[0047] In some preferred embodiments, the clamping assembly 310 includes a first drive cylinder 311 and a clamping block 312. The first drive cylinder 311 is detachably mounted on the platform body 100 through a first fixing hole 202. The first drive cylinder 311 has a first piston rod 3111, which is telescopically connected to the clamping block 312 along a first direction. The first drive cylinder 311 drives the first piston rod 3111 to extend, causing the clamping block 312 to move away from the platform body 100. The clamping block 312 is rotated so that it is positioned above the workpiece 600 to be welded. The first drive cylinder 311 drives the first piston rod 3111 to retract, so that the clamping block 312 clamps the workpiece 600 to be welded.

[0048] In some preferred embodiments, the first drive cylinder 311 has a second fixing hole 3112, and bolts pass through both the second fixing hole 3112 and the first fixing hole 202 to fix the first drive cylinder 311 to the platform body 100. Depending on the different shapes of the workpiece 600 to be welded, the first drive cylinder 311 can be installed in different first fixing holes 202 on the platform body 100, thereby determining the installation position of the clamping assembly 310 on the platform body 100. After welding is completed, the first drive cylinder 311 can simply be removed from the first fixing hole 202 of the platform body 100 and reinstalled according to the next welding requirements.

[0049] In some preferred embodiments, the flat-push assembly 320 includes a second drive cylinder 321 and a flat-push block 322. The second drive cylinder 321 is detachably mounted on the platform body 100 through a first fixing hole 202. The second drive cylinder 321 has a second piston rod 3211, which is telescopically arranged along a second direction and connected to the flat-push block 322. The second drive cylinder 321 drives the second piston rod 3211 to extend, so that the flat-push block 322 pushes against the side of the workpiece 600 to be welded, thereby preventing the workpiece 600 to be welded from shifting along the second direction on the platform body 100. Preferably, the flat-push assembly 320 is disposed on opposite sides of the workpiece 600 to be welded, thereby better fixing the workpiece 600 to be welded.

[0050] In some more preferred embodiments, the second drive cylinder 321 has a third fixing hole 3212, and bolts pass through both the third fixing hole 3212 and the first fixing hole 202 to fix the second drive cylinder 321 to the platform body 100. Depending on the different shapes of the workpiece 600 to be welded, the second drive cylinder 321 can be installed in different first fixing holes 202 on the platform body 100, thereby determining the installation position of the flat-push assembly 320 on the platform body 100. The bolted connection improves the efficiency of installation and disassembly.

[0051] Example 3:

[0052] The difference between this embodiment and Embodiment 2 is that this embodiment further optimizes the structure of the flexible welding platform of this utility model. Please refer to the appendix. Figure 3 .

[0053] The flexible welding platform also includes a pad 500, which is connected to the platform body 100 and has a through hole 501. A mechanical fixing mechanism 300 is connected to the surface of the pad 500 away from the platform body 100. Bolts are inserted through the through hole 501 and the first fixing hole 202 to fix the pad 500 to the platform body 100.

[0054] In this embodiment, the pad 500 serves to elevate the platform. The pad 500 is located between the mechanical fixing mechanism 300 and the surface of the platform body 100. The mechanical fixing mechanism 300 can be screwed into the first fixing hole 202 of the platform body 100 through the pad 500, making the overall structure more stable. At the same time, since the pad 500 elevates the mechanical fixing mechanism 300, the distance between the clamping block 312 and the workpiece 600 to be welded is shortened. This shortens the extension stroke of the first telescopic rod, thereby reducing energy consumption. Furthermore, by elevating the mechanical fixing mechanism 300, the position of the flat pushing component 320 pushing the workpiece 600 to be welded is more suitable, further improving the pushing performance.

[0055] In some preferred embodiments, the first fixing hole 202 is located at the periphery of the positioning hole 201. Multiple first fixing holes 202 are spaced apart along the periphery of the positioning hole 201, thereby increasing the selectivity of the installation position of the mechanical fixing mechanism 300. In this embodiment, three first fixing holes 202 are evenly spaced along the periphery of the positioning hole 201.

[0056] In some preferred embodiments, a countersunk platform 2031 extends from the inner peripheral wall of the mounting hole 203 toward the center of the mounting hole 203. A first fixing hole 202 is also formed on the countersunk platform 2031. The magnetic fixing mechanism 400 is detachably installed in the mounting hole 203 and abuts against the countersunk platform 2031. This enhances the stability of the magnetic fixing mechanism 400 installed in the mounting hole 203. When the magnetic fixing mechanism 400 is not installed in the mounting hole 203, the mechanical fixing mechanism 300 can be fixed to the surface of the platform body 100 through the first fixing hole 202 on the countersunk platform 2031, increasing the usability of the platform body 100 surface and making the flexible welding platform more adaptable to different welding needs.

[0057] In some more preferred embodiments, the magnetic fixing mechanism 400 includes an annular mounting bracket 410 and an electromagnet 420. The annular mounting bracket 410 is installed in the mounting hole 203 and abuts against the recessed platform 2031. The electromagnet 420 is installed in the annular mounting bracket 410. The upper surfaces of the annular mounting bracket 410 and the electromagnet 420 are flush with the upper surface of the platform body 100. A fourth fixing hole 411 is provided on the upper surface of the annular mounting bracket 410. This ensures that the bottom surface of the workpiece 600 to be welded is in contact with the upper surface of the platform body 100, thereby enhancing the friction between the workpiece 600 to be welded and the platform body, making the workpiece 600 to be welded more stable. When the magnetic fixing mechanism 400 is installed in the mounting hole 203, the mechanical fixing mechanism 300 can be fixed to the surface of the platform body 100 through the fourth fixing hole 411 on the annular mounting bracket 410.

[0058] The flexible welding platform of this utility model has multiple positioning holes 201, first fixing holes 202, and mounting holes 203 arranged in an array on the surface of the platform body 100. Several mechanical fixing mechanisms 300 are detachably installed on the platform body 100 through the first fixing holes 202, and several magnetic fixing mechanisms 400 are detachably installed in the mounting holes 203. In this way, the mechanical fixing mechanisms 300 and the magnetic fixing mechanisms 400 can be arranged on the surface of the platform body 100 according to the shape of the workpiece 600 to be welded. When the power source is turned on, the mechanical fixing mechanisms 300 and the magnetic fixing mechanisms 400 fix the workpiece 600 to be welded on the surface of the platform body 100. The welding efficiency is improved through automatic control and it can adapt to the welding needs of workpieces with different shapes.

[0059] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., 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.

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. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0061] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.
