[0061] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0062] Reference Figures 2 to 6 The first exemplary embodiment of the present application provides a chassis panel fixing device 1 (also referred to as a first fixing device), which includes a first fixing seat 3, two first positioning components 6, a plurality of first clamping components 7, a first fixing component and a first clamping component 5.

[0063] Specifically, the first fixed seat 3 is used to support two panel component plates 8 placed along the first direction and to be welded. Two first positioning components 6 are arranged on the first fixed seat 3 facing each other along the first direction, and each first positioning component 6 includes a first slide 12 that can slide along the first direction and a first positioning block 14 that is arranged on the first slide 12 and is used to abut and position the outer edge end wall of the weld end of the two panel component plates 8. The first positioning block 14 is provided with a first embedding protrusion 15 that protrudes along the first direction and is used to embed the weld end of the two panel component plates 8. In addition, a plurality of first clamping components 7 can respectively move along the second direction on the first fixed seat 3 and are used to clamp the two panel component plates 8 together along the second direction, so that the first embedding protrusion 15 abuts and positions the two panel component plates 8 along the second direction. The first fixing component is arranged on the first fixed seat 3 and is used to lock the two panel component plates 8, and the first pressing component 5 is arranged on the first fixed seat 3 and is used to press the two panel component plates 8 toward the first fixed seat 3.

[0064] When manufacturing the chassis panel, the chassis panel fixing device 1 can be used to accurately position the two panel components 8 before welding. When positioning the plates, the two plates to be welded along the first direction are placed on the first fixing seat 3, and then the first slides 12 in the two first positioning components 6 are adjusted and slid along the first direction, so that the first positioning blocks 14 on the two first slides 12 respectively abut against the two ends of the positioning weld, and at the same time, the first embedded protrusions 15 on the two first positioning blocks 14 are respectively embedded in the two ends of the weld, so that the plate stacking can be effectively avoided. Then, the two plates are clamped together along the second direction by multiple first clamping components 7, so that the first embedded protrusions 15 can abut against the two plates in the second direction. In addition, the two plates can be pressed toward the first fixing seat 3 by the first clamping component 5 to prevent the plates from being deformed by heat. The two positioned plates can also be locked by the first fixing component to ensure positioning reliability.

[0065] In some embodiments, both sides of the first embedding protrusion 15 along the second direction are formed as first limiting planes 13. When the plurality of first clamping components 7 clamp two panel component plates 8 together along the second direction, the two first limiting planes 13 of the first embedding protrusion 15 can respectively abut and position the two panel component plates 8. In addition, an embedding guide arc surface protruding toward the ends of the welds of the two panel component plates 8 is connected between the two first limiting planes 13, so that the resistance can be reduced when the first embedding protrusion 15 is embedded in the ends of the welds, so as to facilitate smooth embedding.

[0066] In some embodiments, reference Fig. 9 and Fig.10 The two panel-forming plates 8 are provided with a process rib 35 having a positioning and arc-initiating and extinguishing function at the welding position. Both ends of the process rib 35 (i.e., the arc-initiating and extinguishing plate parts) are provided with grooves. The grooves on the two panel-forming plates 8 together form a first groove 9. At this time, the first embedding protrusion 15 can be embedded in the first groove 9 to abut and position the two panel-forming plates 8 along the second direction, such as by abutting and positioning the two side walls of the first groove 9 through the two first limiting planes 13 mentioned above, so as to abut and position the two panel-forming plates 8 respectively. By providing the first groove 9, the plate can be positioned along the second direction, and the weld width can be limited.

[0067] In addition, the middle portion of the process rib 35 can also be set as a diamond-shaped hollow structure to reduce unnecessary weld welding, thereby saving welding materials.

[0068] In some embodiments, the first fixed seat 3 is plate-shaped and is provided with a first strip-shaped through hole 11 extending in the first direction and penetrating the two side plates of the first fixed seat 3. The first positioning assembly 6 also includes a sliding drive mechanism (such as a screw nut mechanism, etc.) for driving the first slide 12 to slide. In addition, the first slide 12 is configured to be J-shaped and includes a slide straight bar portion and a slide curved portion. The slide straight bar portion passes through the first strip-shaped through hole 11 and its two ends are respectively connected to the first positioning block 14 and the slide curved portion. The sliding drive mechanism is connected between the first fixed seat 3 and the slide curved portion.

[0069] If a welding robot is used for automatic welding, by setting the first strip through hole 11, the plate-shaped first fixing seat 3 can be turned 180° in cooperation with the positioner 4, so that the welding robot automatically passes through the first strip through hole 11 to weld the back of the panel component plate 8, that is, the first strip through hole 11 plays the function of avoiding the welding robot. The J-shaped first slide seat 12 can make the first positioning block 14 and the sliding drive mechanism respectively located on both sides of the plate-shaped first fixing seat 3, making full use of the space of the first fixing seat 3 and avoiding limiting the placement space of the plate due to the installation of the sliding drive mechanism.

[0070] In some embodiments, the first clamping assembly 7 includes a second slide 16 that can slide along the second direction on the first fixed seat 3 (for example, it can be driven to slide by a screw nut mechanism) and a first clamping block 17 arranged on the second slide 16, and the first clamping block 17 is provided with a clamping groove 18 for clamping the two side surfaces of the panel component plate 8. By sliding the second slide 16 along the second direction, the position of the first clamping block 17 can be adjusted according to the size of the plate, ensuring that the plate is clamped by the clamping groove 18, and the two groove side walls of the clamping groove 18 can limit the outer edge of the panel component plate 8 from warping, thereby effectively ensuring the welding quality.

[0071] For example, the clamping groove 18 can be set as a trapezoidal groove, which includes a trapezoidal upper bottom and two trapezoidal waists. When the trapezoidal groove clamps the plate, the trapezoidal upper bottom of the trapezoidal groove can be docked and positioned with the side wall of the panel component plate 8 along the second direction, and the trapezoidal waist can effectively prevent the panel component plate 8 from tilting.

[0072] In some embodiments, the first fixed seat 3 is provided with two first support seats 10 respectively used to support the inner edge of the two panel component plates 8 along the second direction, and the two first support seats 10 extend along the first direction and are arranged in parallel and spaced apart along the second direction (for example, the two first support seats 10 can be distributed outside the two sides of the first strip through hole 11 along the second direction). In addition, the first clamping assembly 5 includes a third slide seat 19 that can move along the second direction on the first fixed seat 3 (for example, driven to slide by a screw nut mechanism) and two first clamping members 20 arranged on the third slide seat 19 and respectively used to align and press the two first support seats 10.

[0073] During welding, the inner edges of the two panel-forming plates 8 along the second direction are closest to the weld and are therefore more susceptible to welding deformation. In this embodiment, the two first support seats 10 respectively support the inner edges of the two panel-forming plates 8 along the second direction, and the sliding of the third slide seat 19 drives the two first clamping members 20 to move to the two first support seats 10 respectively and press-connect them. This can flatten the inner edges of the two panel-forming plates 8 along the second direction, thereby effectively suppressing welding deformation.

[0074] As an example, two third slides 19 may be provided and arranged at intervals along the first direction. The first clamping member 20 may include a clamping seat whose two ends are respectively configured on the two third slides 19, a clamping block movably configured on the clamping seat, and a cylinder connected between the clamping seat and the clamping block. The distance between the clamping block and the plate can be adjusted by the telescopic movement of the cylinder.

[0075] In some embodiments, the first fixing seat 3 is provided with two first supporting seats 10 respectively used to support the inner edges of the two panel component plates 8 along the second direction, and is provided with a plurality of third supporting seats for supporting the panel component plates 8 and respectively extending along the second direction.

[0076] Among them, along the second direction, multiple third support seats are distributed on the outside of the two first support seats 10, and the support height of the first support seat 10 to the panel component plate 8 is greater than the support height of the third support seat to the panel component plate 8, so that the welding deformation of the plate can be predicted, and the plate can be subjected to reverse deformation in advance to offset the welding deformation, thereby improving the flatness of the chassis panel after welding, so that there is no need to perform the leveling process later or the difficulty of leveling can be reduced.

[0077] In some embodiments, the first fixing assembly may include a plurality of first electromagnets disposed on the first fixing seat 3 and used to support and adsorb and lock the panel component plate 8, and the plurality of first electromagnets can adjust their own magnetic attraction to meet the requirements of plate anti-deformation positioning. In addition, the plurality of first electromagnets can be arranged in an X shape on the first fixing seat 3, so as to be able to provide targeted support and adsorption and locking of the X-shaped chassis panel (such as the chassis panel of a pump truck), which is conducive to saving the number of first electromagnets arranged.

[0078] The second exemplary embodiment of the present application further provides a chassis panel production line, which includes the above-mentioned chassis panel fixing device 1.

[0079] In some embodiments, reference Figure 1 , Figure 7 and Figure 8 The chassis panel production line may further include a second fixing device 2, which includes a second fixing seat 21, a second fixing component, a dust suction component 23 and two dust collection components 22.

[0080] Specifically, the second fixed seat 21 is provided with a first hollow portion, two second hollow portions 34 respectively located on both sides of the first hollow portion, and a plurality of second support seats 24 for supporting a chassis panel formed by welding two panels of plate material 8. The second fixed assembly is arranged on the second fixed seat 21 and is used to lock the chassis panel. For example, the second fixed assembly may include a second electromagnet for supporting and adsorbing and locking the chassis panel. The dust collection assembly 23 includes two dust collection members 27 located below the first hollow portion and respectively arranged near the two second hollow portions 34, a dust collection channel 33 formed between the two dust collection members 27 and capable of allowing dust to pass through, and a dust collection member 28 arranged below the two dust collection members 27, and the dust collection member 27 is provided with a dust collection port 29 facing the dust collection channel 33. The two dust collection assemblies 22 are respectively arranged below the two second hollow portions 34 and are used to collect dust.

[0081] After welding the chassis panel, the chassis panel can be placed on the second fixing seat 21, and the chassis panel can be locked by the second fixing assembly, and then additional processing steps such as weld grinding and arc extinguishing plate cutting (such as by a grinding robot, a cutting robot, etc.) can be performed on the second fixing device 2. Dust may be generated when performing the additional processing steps. At this time, the dust can directly fall into the two dust collecting components 22 through the two second hollow parts 34, or fall into the dust collecting component 28 through the first hollow part, the dust collecting channel 33 and the dust suction port 29, thereby collecting dust, improving the air quality around the production line, and reducing the risk of occupational diseases for operators.

[0082] Furthermore, the dust collecting member 27 may include a negative pressure box 30 provided with a dust collecting port 29, a first rotating door 31 hinged at the top of the negative pressure box 30 to be able to flip open and close the dust collecting port 29, and a first driving member 32 for driving the first rotating door 31 to flip. When dust needs to be collected, the negative pressure box 30 may be connected to a negative pressure air source, and the first driving member 32 may drive the first rotating door 31 to open the dust collecting port 29. Under the action of negative pressure, a strong suction force may be provided to quickly suck dust into the negative pressure box 30, and then collected in the dust collecting member 28.

[0083] In some embodiments, after the chassis panel is welded, the first groove 9 is left on the arc-initiating and extinguishing plate of the chassis panel. At this time, a second positioning block 25 can be provided on the second fixing seat 21, and a second embedding protrusion 26 is provided on the second positioning block 25, so that the second embedding protrusion 26 can be embedded in the first groove 9 to center the chassis panel, and then the chassis panel can be locked by the second fixing assembly.

[0084] In some embodiments, the chassis panel production line may also include a control device electrically connected to the chassis panel fixing device 1 and the second fixing device 2, which automatically controls the chassis panel fixing device 1 and the second fixing device 2 to perform corresponding panel positioning actions, thereby improving the degree of automation of the production line.

[0085] In some embodiments, the control device includes a processor, a memory, and a computer program stored in the memory, wherein the computer program can be executed by the processor to implement the following steps:

[0086] S1, control the two first slides 12 to move, and respectively embed the two first embedding protrusions 15 into the two ends of the weld of the two panel component plates 8;

[0087] S2, after the handling robot places the panel component plate 8 on the first support seat 10 and the first groove 9 of the panel component plate 8 is stuck in the first embedding protrusion 15, the second slide seat 16 is controlled to move toward the first strip through hole 11 to press the panel component plate 8 against the first embedding protrusion 15;

[0088] S3, controlling the first electromagnet on the first fixing seat 3 to adsorb and lock the panel component plate 8;

[0089] S4, controlling the first pressing assembly 5 to move from the initial position to above the first supporting seat 10, and then pressing the panel component plate 8 onto the first supporting seat 10;

[0090] S5, after the welding of the weld position of the panel component plate 8 toward the first clamping assembly 5 is completed, the positioner 4 is controlled to rotate the first fixing seat 3 so that the side of the panel component plate 8 away from the first clamping assembly 5 faces upward, so that the welding robot can penetrate the first strip through hole 11 to weld the back side of the panel component plate 8;

[0091] S6, after the welding is completed on the side of the panel component plate 8 away from the first clamping assembly 5, the positioner 4 is controlled to rotate the first fixed seat 3 so that the panel component plate 8 faces the side of the first clamping assembly 5 upward, and then the first clamping assembly 5 is controlled to move to the initial position, the first electromagnet on the first fixed seat 3 releases the chassis panel, and the second slide 16 and the first slide 12 move in the direction away from the chassis panel;
