Using a programmable logic controller (PLC) as its control core, it can precisely control various parameters and actions of the welding station, enabling accurate positioning of the welding position to ensure the welding components are in the correct location during welding, thus improving welding precision. It can also automatically regulate key parameters such as pressure, temperature, and welding time during the welding process to adapt to the welding needs of workpieces of different materials and specifications. Furthermore, it can work in conjunction with welding equipment to achieve automated welding processes, improving welding efficiency and quality, and reducing human error. It plays a vital role in various industries requiring welding processes, such as electronics manufacturing, machining, and automotive parts production.

[0003] To address the aforementioned issues, existing patents offer solutions. Most existing PLC-controlled welding station fixtures use clamping cylinders for positioning. With this method, after each section of welding is completed, the user needs to manually adjust the angle between the two welding items. After adjusting the angle, the clamping is repeated, increasing the user's workload and potentially causing inconsistent welding positions.

[0004] To address this, a PLC-controlled welding table fixture is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a PLC-controlled welding table fixture that solves the problem that most existing PLC-controlled welding table fixtures use clamping cylinders for limiting the position. When using clamping cylinders for limiting the position, after each part is welded, the user needs to manually adjust the angle between the two welding items, and then clamp them again after adjusting the angle. This is repeated every time, increasing the user's workload and potentially causing inconsistent welding positions.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A PLC-controlled welding station fixture includes a clamping assembly 1, a base 2 fixedly connected to the bottom of the clamping assembly 1, a protective cover 3 fixedly connected to the top of the base 2, a welding device 4 fixedly connected to the top of the base 2, and a dust collection assembly 5 disposed inside the protective cover 3.

[0027] The clamping assembly 1 includes a base plate 101. A servo motor 102 is fixedly connected to the bottom of the base plate 101. An adjustment plate 103 is fixedly connected to the top of the servo motor 102. An adjustment groove 104 is opened on the top of the adjustment plate 103. A motor 105 is fixedly connected to the right side of the adjustment plate 103. A bidirectional spiral rod 106 is fixedly connected to the left side of the motor 105. Two adjustment blocks 107 are threadedly connected to the surface of the bidirectional spiral rod 106. A top plate 108 is fixedly connected to the top of each of the two adjustment blocks 107. A clamping mold 109 is snapped into the interior of each of the two top plates 108.

[0028] In this embodiment: Clamping component 1 is used to clamp and fix the welding items, achieving automated angle and position adjustment, replacing the traditional manual adjustment method, reducing workload and ensuring consistent welding position. Base 2 serves as the basic support structure for the entire welding table fixture, with a protective cover 3, welding device 4, and clamping component 1 fixedly connected to the top, stabilizing the overall structure. The protective cover 3, surrounding the welding area, provides protection, preventing sparks and spatter from injuring operators and reducing external environmental interference. Welding device 4 performs welding operations, welding the items fixed to clamping component 1 according to set parameters under PLC control. Dust extraction component 5 absorbs fumes and exhaust gases generated during welding, improving the working environment and protecting operator health. Base plate 101 serves as the basic load-bearing structure for clamping component 1, with a servo motor 102 fixedly connected to the bottom and an adjustment plate 103 supporting the top. The servo motor 102 provides power to drive the adjustment plate 103 to rotate, thereby... The angle of the welded item held in a movable clamp can be adjusted without manual operation. An adjustment plate 103 with an adjustment groove 104 at the top provides a track for the movement of the adjustment block 107, while also supporting components such as the motor 105 and the bidirectional spiral rod 106. The adjustment groove 104 restricts the movement path of the adjustment block 107, ensuring stable linear movement under the drive of the bidirectional spiral rod 106. The motor 105 drives the bidirectional spiral rod 106 to rotate, providing power for the movement of the adjustment block 107. The bidirectional spiral rod 106 has a threaded direction on its surface. Conversely, rotation can drive the two adjusting blocks 107 to move simultaneously in opposite directions, thereby adjusting the distance between the two clamping molds 109. By setting the adjusting blocks 107, they move along the adjusting groove 104 under the action of the bidirectional spiral rod 106, thereby driving the top plate 108 and the clamping molds 109 to move. The top plate 108 is used to install and fix the clamping molds 109, and its position is adjusted as the adjusting blocks 107 move. The clamping molds 109 directly contact the welding items and are designed to fit the shape of the welding items, thereby achieving stable clamping of the items.

[0029] Specifically, such as Figure 3 As shown, the vacuuming assembly 5 includes an electric telescopic rod 501, with an air intake hood 502 fixedly connected to the bottom of the electric telescopic rod 501. A connecting pipe 503 is connected to the bottom of the air intake hood 502, and a housing 504 is connected to the side of the connecting pipe 503 away from the air intake hood 502.

[0030] Specifically, such as Figure 3 As shown, a hollow tube 505 is connected to the right side of the housing 504, and a fan body 506 is fixedly connected inside the hollow tube 505.

[0031] Specifically, such as Figure 3 As shown, the top of the housing 504 is provided with a plug-in groove 507, and a filter plate 508 is snapped into the inside of the plug-in groove 507. A pull-out block 509 is fixedly connected to the top of the filter plate 508.

[0032] In this embodiment: An electric telescopic rod 501 is provided to extend and adjust the height of the air intake hood 502, allowing it to better align with the area where welding fumes are generated, thus improving dust collection efficiency. The air intake hood 502 serves as the inlet for fumes, drawing them in through its opening towards the fume source. A connecting pipe 503 connects the air intake hood 502 and the housing 504, transporting the fumes into the housing 504. The housing 504 serves as a container for fume treatment and filtration, containing a filter plate 508 to purify the incoming fumes. A hollow tube 505 connects the housing 504 to the outside environment for further purification. The system provides a channel for air exhaust and houses an internal fan body 506. The fan body 506 generates negative pressure during operation, causing dust and smoke inside the protective cover 3 to enter the housing 504 through the air inlet hood 502 and connecting pipe 503, thus achieving a dust extraction function. A insertion slot 507 provides an installation position for the filter plate 508, facilitating its insertion and removal for cleaning or replacement. The filter plate 508 filters the dust and smoke entering the housing 504, adsorbing harmful particles and substances to purify the air. A pull-out block 509 is fixed to the top of the filter plate 508, allowing operators to easily remove the filter plate 508 from the insertion slot 507 for maintenance.

[0033] Specifically, such as Figure 3 As shown, a protective sleeve 6 is snapped onto the surface of the hollow tube 505, and a filter screen 7 is fixedly connected inside the protective sleeve 6.

[0034] Specifically, such as Figure 1 , Figure 4 As shown, hinges 8 are bolted to the left and right sides of the protective cover 3, and protective doors 9 are bolted to the opposite sides of the two hinges 8. Adjustment handles 10 are fixedly connected to the front of the two protective doors 9.

[0035] In this embodiment: the protective sleeve 6 is snapped onto the surface of the hollow tube 505, protecting the hollow tube 505 and the internal filter screen 7 from damage caused by external objects. The filter screen 7, fixed inside the protective sleeve 6, further filters the air discharged from the housing 504 through the hollow tube 505, improving air purification and preventing the discharge of incompletely filtered fine particles. Hinges 8 are attached to the left and right sides of the protective cover 3 and the corresponding protective doors 9, allowing the protective doors 9 to rotate around the hinges and open and close. The protective doors 9, connected to the protective cover 3 via the hinges 8, can close the opening of the protective cover 3 when closed, enhancing the protective effect, and facilitate the placement or removal of welding items when open. An adjustment handle 10 is fixed to the front of the protective door 9, making it easier for the operator to hold and open the protective door 9, thus making operation more convenient.

[0036] Specifically, such as Figure 5 As shown, the electric telescopic rod 501 is bolted to the rear side of the inner wall of the protective cover 3, and the housing 504 is bolted to the rear side of the protective cover 3.

[0037] Specifically, such as Figure 2 As shown, splicing grooves 11 are provided on the front and rear sides of the inner walls of the two top plates 108, and splicing blocks 12 are fixedly connected to the surfaces of the two clamping molds 109.

[0038] In this embodiment: by setting splicing groove 11 and splicing block 12, the inner wall of splicing block 12 and splicing groove 11 are engaged to achieve the engagement and fixation of clamping mold 109 and top plate 108, ensuring the stable installation of clamping mold 109 on top plate 108.

[0039] Working principle: First, the operator opens the protective door 9 by adjusting handle 10, and places the item to be welded between the two clamping molds 109 of the clamping assembly 1. The top plate 108 cooperates with the splicing blocks 12 and splicing grooves 11 on the surface of the clamping molds 109 to ensure that the clamping molds 109 are securely clamped onto the top plate 108. Then, the motor 105 is started, driving the bidirectional spiral rod 106 to rotate. Because the threads on the surface of the bidirectional spiral rod 106 are opposite, the two adjusting blocks 107 connected by their threads will move simultaneously towards each other along the adjusting grooves 104 on the adjusting plate 103, causing the top plate 108 and the clamping molds 109 to approach and clamp the item to be welded, completing the automatic clamping and fixing. During the welding process, the welding device 4 welds the item according to preset parameters under PLC control. If the welding angle needs to be adjusted, the servo motor 102 can drive the adjusting plate 103 to rotate, causing the clamped item to rotate synchronously to the desired position. The system requires no manual operation and ensures consistent welding positions. Simultaneously, the electric telescopic rod 501 adjusts the height of the air intake hood 502 to align with the welding fume area. The fan body 506 activates, generating negative pressure to draw the fumes from the protective cover 3 into the housing 504 via the air intake hood 502 and connecting pipe 503. The filter plate 508 inside the housing 504 performs initial filtration of the fumes, and the purified air is discharged through the hollow tube 505. The filter screen 7 inside the hollow tube 505 further filters fine particles. The protective sleeve 6 protects the hollow tube 505 and the filter screen 7. The filter plate 508 can be removed from the insertion slot 507 via the pull-out block 509 for cleaning or replacement. After welding, the motor 105 reverses the direction of the bidirectional spiral rod 106, causing the adjusting block 107 to reset the clamping mold 109 and release the workpiece. The operator can then open the protective door 9 to remove the workpiece. The entire process is automated, reducing manual intervention and improving efficiency and precision.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
