At present, the tooling positioning platform of the corbel is usually simply positioned by screw support and two plywood. In this way, since the screw only has a supporting force on the steel parts and has no limiting effect on the steel parts, the fixing performance is poor and the positioning accuracy is low. The tooling positioning platform in the related technology achieves positioning by fixing the tooling trunk with four plywood, which increases the fixing performance of positioning.

[0038] At present, the existing tooling positioning platform is prone to deviation or even collapse when the workpiece with welding is placed vertically, which is difficult to operate. The positioning platform provided by the present invention adopts multiple clamps to realize the positioning and clamping of the workpiece for welding. The following are some embodiments:

[0039] refer to Figure 1 and Figure 2 , an embodiment of the present invention provides a positioning platform, comprising:

[0040] The bottom plate 200, the first clamp 300 and the side plate group. The first clamp 300 includes a plurality of clamping components, the clamping components include a first clamping member 320 and a second clamping member 330, and the first clamping member 320 and the second clamping member 330 are used to clamp the workpiece to be welded along a first direction. The first direction is Figure 2 The front-to-back direction is shown in .

[0041] The side support plate group includes a first side support plate 410 and a second side support plate 420. The first side support plate 410 and the second side support plate 420 are respectively arranged on both sides of the first clamp 300, at least one of the first side support plate 410 and the second side support plate 420 is slidably connected to the bottom plate 200, and the first side support plate 410 and the second side support plate 420 are used to clamp the first workpiece to be welded clamped by the first clamp 300 along the second direction, and the second direction is perpendicular to the first direction; the second clamp includes a third clamping member 520 and a fourth clamping member 530, and the third clamping member 520 and the fourth clamping member 530 are used to clamp the second workpiece to be welded along the first direction, and the second clamp 500 is arranged on the first side support plate 410. The second direction is Figure 2Left and right directions as shown in .

[0042] The positioning accuracy is improved by the limiting effect of the first clamp 300 and the side plate group in two directions, and the second workpiece to be welded is prevented from sliding or collapsing by the clamping force between the third clamp and the fourth clamp. Compared with the positioning platform without the second clamp 500, it can effectively prevent the workpiece from sliding or collapsing during the positioning process of the vertically placed workpiece, reduce the difficulty of manual operation, and improve the assembly efficiency of the workpiece.

[0043] Reference Figure 1 and Figure 2 Another embodiment of the present invention provides a positioning platform, including: a base plate 200, a first fixture 300, a side plate group, two first transmission assemblies 310, a second transmission assembly 430, a third transmission assembly 510 and a fourth transmission assembly 610. The side plate group includes a first side plate 410 and a second side plate 420 distributed on both sides of the base plate 200. The first side plate 410 and the second side plate 420 are arranged on both sides of the first fixture 300. The two first transmission assemblies 310 and the second transmission assembly 430 are arranged on the base plate 200, the third transmission assembly 510 is arranged on the first side plate 410, and the fourth transmission assembly 610 is arranged on the first side plate 410.

[0044] In this embodiment, the first clamp 300 includes two clamping assemblies. The first clamping assembly includes a first clamping member 320 and a second clamping member 330. The first clamping member 320 and the second clamping member 330 are respectively connected to the first transmission assembly 310. The first transmission assembly 310 extends along the first direction.

[0045] The first clamp 300 can be set to one clamping assembly or more than two clamping assemblies. The first clamp 300 can also achieve the clamping or loosening of the first workpiece to be welded. The way in which the first clamp 300 clamps or loosens the first workpiece to be welded is the same as the above-mentioned way. The more clamping assemblies are set on the first clamp 300, the better the limiting effect of the first workpiece to be welded. In practical applications, the number of clamping assemblies is determined according to the size of the workpiece to be welded.

[0046] The side support plate group includes a first side support plate 410 and a second side support plate 420, and the first side support plate 410 and the second side support plate 420 are distributed on both sides of the first clamp 300. The first side support plate 410 is provided with a second clamp 500, and the second clamp 500 includes a third clamping member 520 and a fourth clamping member 530. The third transmission assembly 510 is provided on the first side support plate 410, and the third clamping member 520 and the fourth clamping member 530 are respectively connected to the third transmission assembly 510, and the third transmission assembly 510 drives the third clamping member 520 and the fourth clamping member 530 to move along the first direction.

[0047] The second clamp 500 is slidably connected to the first side support plate 410, and the second clamp 500 moves along the first direction on the first side support plate 410 to clamp the workpiece to be welded. The movable connection can be achieved by sliding through a slide groove or a slide rail, or by driving the third clamp 520 and the fourth clamp 530 to move through a transmission component.

[0048] The first side support plate 410 includes a first abutment plate, and the second clamp 500 extends along the second direction and protrudes from the first abutment plate. Specifically, the first connection portion 521 of the third clamp 520 connected to the first side support plate 410 extends along the second direction to a protruding position relative to the vertical cross section, and the protruding portion of the first connection portion 521 relative to the vertical cross section is the portion for clamping the workpiece to be welded. The fourth clamp 530 is configured in the same manner as the third clamp 520. The second workpiece to be welded is placed in the second clamp 500 in a fit, and the second workpiece to be welded will be supported under the thrust of the first workpiece to be welded during assembly. The second workpiece to be welded will not slide or collapse after being supported by the first abutment plate, and has a good limiting and fixing effect. It can be arranged below or above the second clamp 500, or in the middle of the second clamp 500.

[0049] In this embodiment, the third clamping member 520 includes a first connection portion 521 and a first limiting portion 522, and the first limiting portion 522 and the first connection portion 521 form a first groove facing the fourth clamping member 530. The first connection portion 521 is movably connected to the first side support plate 410. When the second workpiece to be welded is placed on the second clamp 500, the first limiting portion can support the second workpiece to be welded, and when the second workpiece to be welded is not supported by the first welding member, the workpiece to be welded can be prevented from collapsing.

[0050] The fourth clamping member includes a second connecting portion 531 and a second limiting portion 532. The second connecting portion 531 is movably connected to the first side support plate 410. The second limiting portion 532 and the second connecting portion 531 form a second groove. The second groove is oriented in a direction opposite to the first groove. The second limiting portion 532 has the same function as the first limiting portion 522.

[0051] In the positioning platform of this embodiment, the first side support plate 410 and the second side support plate 420 are both slidably connected to the bottom plate 200. Specifically, a plurality of slide grooves 421 are provided at the bottom of the first side support plate 410 and the second side support plate 420, and the bottom plate 200 is provided with a slide rail 210 at a position corresponding to the slide groove 421, and the slide rail 210 extends along the second direction. Figure 3 and Figure 4The second side support plate 420 has two slide grooves 421 at the bottom, and the bottom plate 200 has two slide rails 210 at corresponding positions, and the second side support plate 420 can move in the second direction along the slide rails 210. When the first side support plate 410 approaches the second side support plate 420, the second side support plate 420 can also make corresponding position adjustments in the second direction.

[0052] The slide groove 421 and the slide rail 210 may be provided with one or more. In the embodiment where the second side support plate 420 bears a larger load, providing multiple slide grooves 421 and slide rails 210 can better distribute the weight of the side support plate group.

[0053] In the positioning platform of other embodiments of the present invention, only one of the first side support plate 410 and the second side support plate 420 is slidably connected to the bottom plate 200, and the first workpiece to be welded clamped by the first fixture 300 and the second workpiece to be welded clamped by the second fixture 500 are assembled and positioned by sliding the first side support plate 410 or the second side support plate 420 slidably connected to the bottom plate 200 in the second direction. Compared with the positioning platform in which only one of the first side support plate 410 and the second side support plate 420 is slidably connected to the bottom plate 200, there is a larger positioning space, and the assembly and positioning of the workpieces to be welded are more flexible.

[0054] In some other embodiments of the present invention, the second side plate 420 and the slide rail 210 are connected to one end of the second side plate 420 through an elastic member 422. During the assembly and positioning process, the second side plate 420 is subjected to the extrusion force of the first workpiece to be welded due to the proximity of the first side plate 410. The elastic force generated by the elastic member 422 has a certain buffering effect. Compared with the embodiment without the elastic member 422, the second side plate 420 is more stable in the position adjustment of the positioning. The second side plate 420 will not slide due to the elastic force of the elastic member 422. After the positioning is completed, the elastic force of the elastic member 422 disappears due to the distance from the first side plate 410, and the second side plate 420 can be automatically reset. By setting the elastic member 422, the second side plate 420 can complete the positioning process without the transmission assembly, and the structure is simple and practical. The type and material of the elastic member 422 are determined according to factors such as the size of the extrusion force of the first workpiece to be welded on the second side plate 420, including but not limited to various types of springs.

[0055] In this embodiment, a transmission assembly is provided, wherein the first clamping member 320 and the second clamping member 330 are connected to the first transmission assembly 310, the first side support plate 410 is connected to the second transmission assembly 430, and the third clamping member 520 and the fourth clamping member 530 are connected to the third transmission assembly 510. The first transmission assembly 310 is used to drive the first clamping member 320 and the second clamping member 330 to move along the first direction, the second transmission assembly 430 is used to drive the first side support plate 410 to move along the second direction, and the third transmission assembly 510 is used to drive the third clamping member 520 and the fourth clamping member 530 to move along the first direction.

[0056] In this embodiment, the first side support plate 410 is connected to the second transmission assembly 430, and the second transmission assembly 430 drives the first side support plate 410 to move along the second direction. After the first workpiece to be welded and the second workpiece to be welded are clamped and position adjusted, the first side support plate 410, driven by the second transmission assembly 430, pushes the second workpiece to be welded toward the first workpiece to be welded along the second direction, completing the assembly positioning of the second welding and the first workpiece to be welded.

[0057] In some other embodiments of the present invention, the first side support plate 410 and the second side support plate 420 are connected to the same second transmission assembly 430. During the assembly and positioning process, the first side support plate 410 and the second side support plate 420 can both move along the second direction, which can improve the positioning efficiency.

[0058] Specifically, in some embodiments of the present invention, the first transmission assembly 310 is a screw mechanism, and the first clamping member 320 is connected to the first transmission assembly 310, and the position of the first clamping member 320 can be adjusted by manually rotating the screw. The method of adjusting the position of the clamping members on the first side support plate 410, the second side support plate 420 and the second clamp 500 is the same as the method of adjusting the position of the clamping member of the first clamp. While the transmission mechanism drives the clamping member or the side support plate to move, it can also limit the clamping member or the side support plate in the moving direction, and the movement cannot occur without the drive of the transmission mechanism. The transmission assembly is provided to facilitate manual adjustment, and after positioning, no additional fixing method is required to prevent the clamping member or the side support plate from sliding.

[0059] In this embodiment, the first transmission assembly 310 is connected to the first driving member 311, the second transmission assembly 430 is connected to the second driving member 431, the third transmission assembly 510 is connected to the third driving member 511, and the fourth transmission assembly 610 is connected to the fourth driving member 611. The load is driven by the driving member and moves in one direction through the transmission mechanism. Its form includes but is not limited to a linear motor mechanism, a cylinder mechanism, and a screw transmission mechanism driven by various driving members, a belt transmission mechanism, a rack mechanism, etc.

[0060] In some transmission mechanisms, one driving member can be used to drive two loads to perform linear motion in opposite directions, such as a bidirectional screw mechanism. In other transmission mechanisms, one driving member usually only drives one load to perform linear motion. In the present invention, the transmission assembly controls the relative movement between the clamping members of the first clamp 300 and the clamping members of the second clamp 500 to achieve workpiece positioning, so in the above-mentioned general mechanism, two driving members can be set in each transmission assembly to achieve the movement of the two clamping members, or each transmission assembly can have only one driving member, and each clamping member is separately set on a transmission assembly.

[0061] The driving part can be various motors, cylinders, hydraulic cylinders and other components. In practice, the preferred solution is selected according to factors such as accuracy, platform size, and the vertical positioning range of the workpiece to be welded. For example, in an embodiment where welding accuracy is high, a servo motor is selected as the driving part to improve the positioning accuracy. By setting the driving part, the positioning position can be adjusted by controlling the driving part during the positioning process, which reduces manual operation and increases positioning accuracy.

[0062] In the positioning platform of this embodiment, the first transmission assembly 310 uses a bidirectional roller screw as a transmission member, a servo motor as a driving member, a first clamping member 320 and a second clamping member 330 are connected to both sides of the bidirectional ball screw, and the servo motor drives the bidirectional ball screw to rotate, and the first clamping member 320 and the second clamping member 330 move closer or farther on the bidirectional ball screw. The second clamping assembly is configured in the same manner as the first clamping assembly.

[0063] The process of the first clamp 300 clamping the first workpiece to be welded is as follows: the first workpiece to be welded is vertically placed between the two clamping members of the first clamping assembly and the two clamping members of the second clamping assembly at the same time, and the two clamping members connected to the same first transmission assembly 310 are approached on the bidirectional ball screw as the servo motor is turned when the servo motor is started, until the first workpiece to be welded is clamped. After welding is completed, the clamping members arranged on the same first transmission assembly 310 in the first clamp 300 move away from each other as the servo motor rotates, and the workpiece to be welded is released. Among them, vertical placement means that a narrow side surface of the first workpiece to be welded is erected on the base plate 200 as the bottom surface, and at this time, the clamping direction of the two clamping members in the clamping assembly is the thickness direction of the first workpiece to be welded.

[0064] The process of the second clamp 500 clamping the second workpiece to be welded is as follows: the second workpiece to be welded is vertically placed between the third clamp 520 and the fourth clamp 530, and the third transmission assembly 510 drives the third clamp 520 and the fourth clamp 530 to move toward each other until the third clamp 520 and the fourth clamp 530 clamp the second workpiece to be welded. After welding is completed, the third transmission assembly 510 drives the third clamp 520 and the fourth clamp 530 to move away from each other to release the second workpiece to be welded.

[0065] The second side support plate 420 of the positioning platform in this embodiment is also provided with a second fixture 500, which is movably connected to the second side support plate 420, and the second side support plate 420 includes a second abutment plate 424, and the second fixture extends along the second direction and protrudes from the second abutment plate 424, and the second abutment plate 424 can abut the workpiece to be welded clamped by the second fixture 500 after positioning is completed. The two clamping members of the second fixture 500 on the second side support plate 420 are connected to the fourth transmission assembly 610, which is provided on the second side support plate 420, and the fourth transmission assembly 610 drives the two clamping members of the second fixture 500 on the second side support plate 420 to move along the first direction.

[0066] In some other embodiments of the present invention, the second clamp 500 of the second side support plate 420 may also adjust the clamping position through the above-mentioned transmission assembly or through a sliding connection with the second side support plate 420 .

[0067] In some other embodiments of the present invention, the second side support plate 420 is not provided with the second clamp 500 , and the second side support plate 420 is only used to clamp the first workpiece to be welded along the second direction.

[0068] Compared with the case where the second side support plate 420 is not provided with the second fixture 500 , the second side support plate 420 is also provided with the second fixture 500 to increase the positioning of a workpiece.

[0069] Reference Figure 2 In this embodiment, the first side support plate 410 includes a first side support bottom plate 411, and a first roller portion 432 is arranged on the first side support bottom plate 411. The first roller portion 432 is arranged below the third clamping member 520 and the fourth clamping member 530, and the first roller portion 432 extends in parallel with the first direction. The second side support plate 420 includes a second side support bottom plate 423, and a second roller portion 433 is arranged on the second side support bottom plate 423. The first roller portion 432 is arranged below the fifth clamping member 620 and the sixth clamping member 630, and the second roller portion 433 extends in parallel with the first direction.

[0070] After the second clamp 500 clamps the second workpiece to be welded, the corresponding position adjustment will be made on the third transmission assembly 510 to position the second workpiece to be welded at the preset corresponding position. At this time, the second workpiece to be welded will slide on the first side support plate 410. At this time, the sliding friction is likely to cause wear to the welded workpiece. The first roller portion 432 can convert the sliding friction between the second workpiece to be welded and the first side support plate 410 into rolling friction, which is convenient for adjusting the position of the second workpiece to be welded and reducing the wear between the second workpiece to be welded and the first side support plate 410. The length and width design of the first roller portion 432 is determined according to the size of the workpiece to be welded in the main application. The same is true for setting the second roller portion.

[0071] Reference Figure 2 In some other embodiments of the present invention, a third roller portion 441 is provided on the second side support plate 423, and a fourth roller portion 442 is provided on the second side support plate 423. The third roller portion 441 and the fourth roller portion 442 extend along the second direction. When the first workpiece to be welded is clamped by the first fixture 300 and placed on the first side support plate 411 and the second side support plate 423, the third roller portion 441 and the fourth roller portion 442 support the first workpiece to be welded, and the friction between the first workpiece to be welded and the first side support plate 410 and the second side support plate 420 is converted into rolling friction, thereby reducing the wear of the first workpiece to be welded.

[0072] The third roller section 441 may be provided with one roller or multiple rollers. The multiple rollers may be provided with the same length and width or with different widths and lengths; they may be provided with equal intervals or with unequal intervals. The width and length of the rollers are determined according to the size of the workpiece to be welded. The fourth roller section is provided in the same manner.

[0073] In some other embodiments of the present invention, the positioning platform further includes an input device and an information processor, wherein the input device is used to manually input welding parameter information, and the input welding parameter information includes information such as the assembly quantity of the steel structure, the size of each workpiece to be welded, and the welding position.

[0074] Among them, input devices include but are not limited to mouse, keyboard, camera, scanner, light pen, handle, voice input device and other devices.

[0075] The input device is electrically connected to the information processor, and the input device is connected to the information processor. After the positioning platform receives the execution signal, the information processor receives the input welding parameter information and controls the transmission component to complete the corresponding execution operation. The information processor refers to an electronic component that includes arithmetic logic components, register components, and control components, and has the functions of processing instructions, executing operations, controlling time, and processing data, such as a PLC programmable controller.

[0076] Taking a corbel including a web and two wing plates welded and assembled as an example, the welding and assembly process of the entire corbel is as follows: input the specification parameters of the corbel in the input device, including: the number of three assemblies, the size information of the two wing plates and the web, the position of the two wing plates and the web for welding and assembly, and other information. After entering the parameters, the second fixture 500, the first side support plate 410, and the second side support plate 420 will move to a suitable position so that the web can fall on the first side support bottom plate 411 and the second side support bottom plate 423, and the wing plate is manually carried to the second fixture 500, and the linear actuator is controlled to clamp the wing plate. In some other embodiments of the present invention, the second fixture 500 is provided with a detection sensor, and the detection sensor detects that the wing plate is in place and controls the second fixture 500 to automatically clamp the wing plate. The clamping method of the other wing plate and the web is the same as that of the wing plate.

[0077] After the two wing plates and the web are clamped, the execution signal of the information processor is transmitted to each transmission component, and each transmission component drives each fixture to perform the corresponding position movement, so that the two wing plates and the web are fitted at the welding position, and welding begins at this time. After welding, the end signal is input into the input device, and the end signal is transmitted to the information processor. The information processor randomly sends out the end execution signal of each fixture, and controls each transmission component on the positioning platform to drive each fixture to release the wing plate and the web after receiving the end execution signal. After manually removing the welded corbel, the assembly of the entire corbel is completed.

[0078] In the positioning platform of this embodiment, relevant welding parameter information is input into the input device, and the information processor is used to control the transmission assembly to drive each fixture to move, and finally the assembly positioning of the workpiece to be welded is realized. The whole welding process has a high degree of automation, which improves the assembly efficiency, reduces manual operation, and improves the assembly accuracy.

[0079] In some other embodiments of the present invention, the positioning platform further includes a display. The display can be any electronic device that converts digital signals into image displays, such as a liquid crystal display. In some embodiments, both the input device and the display are touch screens, which can save space and facilitate operation. The display is connected to the input device, and the display receives the welding parameter information signal in the input device and displays it.

[0080] In some other embodiments of the present invention, the positioning platform also includes a data storage device, which is electrically connected to the display and the information processor. The data storage device records the real-time data of the positioning platform and records the welding parameter information. Among them, the real-time data includes information such as the positioning working time, the working voltage of the transmission component, and the working current of the transmission component. When the input welding parameter information is transmitted to the information processor, the information processor will send the welding parameter information to the data storage device for storage. The data storage device refers to an electronic component that can read data and store it for a long time, including but not limited to random access memory, read-only memory and other storage devices.

[0081] The data storage device sends the recorded real-time data and welding parameter information to the display for display and saves the recorded real-time data and welding parameter information. By setting up the data storage device, the relevant real-time data of the welding equipment can be monitored on the display. The storage function of the data storage device can trace the processing information of the welding workpiece, which is convenient for workpiece management.

[0082] In some other embodiments of the present invention, the first clamp 300 and the second clamp 500 are provided with detection sensors. When the detection sensor detects that the workpiece to be welded is vertically placed in the first clamp 300 and the second clamp 500, the detection sensor transmits a positioning signal to the signal processor, and the signal processor controls the transmission component on the positioning platform so that the corresponding clamp clamps the workpiece to be welded. The detection sensor is provided to facilitate people to automatically clamp the workpiece to be welded after carrying the workpiece to be welded, thereby improving the efficiency of assembly. The setting of the detection sensor and the connection method with the external control system are well-known technologies in the relevant field and will not be repeated here.

[0083] In some other embodiments of the present invention, the second fixture 500 is provided with a laser detector, and the laser detector is electrically connected to the signal processor. When the workpiece to be welded is placed vertically in the second fixture 500, there is a deviation in the placement of the workpiece to be welded. The laser detector is set to detect the vertical level accuracy. When the vertical accuracy is lower than the preset value, the signal processor receives a signal to remind manual rearrangement. The addition of a laser detector can avoid the accuracy error caused by manual placement errors and improve the accuracy of assembly positioning.
