[0025] During implementation, 10-30 clamping modules are arranged in sequence in the main frame, and each clamping module includes a group of symmetrically arranged T-shaped liftable pressure heads. A panel is provided on the surface of the main frame, and slots matching the pressure heads are provided on the panel. These slots can be used for lifting and lowering the pressure heads. When the clamping module rises, the workpiece can be positioned horizontally and vertically by the pressure head and the longitudinal positioning block. By adjusting the position of the pressure head, the clamping force is gradually increased, and the clamping range can be infinitely adjusted, which can not only ensure the clamping force but also reduce the deformation of the workpiece that may be generated during welding. When the clamping module descends, the pressure head will be completely under the panel, and the entire clamping device can be used as a working platform with a wide range of applications and strong variability.

[0026] All the lifting and lowering pressure heads of the present invention can be synchronously aligned, and the pressing modules are independently driven, which can ensure good pressing force. At the same time, the present invention can also be used as a common workbench, and has a wide range of applications.

[0028] like Figure 1 As shown, the welding fixture device includes a main frame of a rectangular structure, in which 15 clamping modules are arranged in sequence, and the spacing between adjacent clamping modules is the same.

Under the drive of the clamping drive device, the pressure head and the transverse slider will move downward, and the upper part of the pressure head will press the bottom of the T-shaped workpiece to fix the workpiece.

[0030] Furthermore, a slidable longitudinal slider is provided on the longitudinal guide rail, and the longitudinal slider and the transverse slider are connected by a set of hinge rods, so that a rotatable connection is formed between the hinge rod and the longitudinal slider, and between the hinge rod and the transverse slider.

Adjacent longitudinal sliders are connected by connecting rods, and the longitudinal slider can move along the longitudinal guide rail under the action of the middle driving device. The two pressure heads of each clamping module here are arranged in parallel, and the pressure heads are T-shaped. The T-shaped structure includes a transverse pressure plate and a longitudinal connecting column. An elastic pressure strip is provided under the transverse pressure plate to ensure that the workpiece is not easily deformed. Chamfers are provided around the longitudinal connecting column to facilitate up and down movement without jamming. When in use, the two pressure heads move synchronously toward or away from each other under the action of the hinge rod to adjust the spacing between the two pressure heads.

[0031] Example 2

[0032] A method for using a T-shaped structure anti-deformation welding fixture device, which is different from the prior art in that the method comprises the following steps: a. When the anti-deformation welding fixture device is used as a fixture, multiple clamping modules in a main frame rise so that each pair of pressure heads on the clamping die is higher than a panel, and a T-shaped structure workpiece is placed between the two pressure heads; b. One end of the T-shaped structure workpiece is attached to the longitudinal positioning block on the panel so that the workpiece is longitudinally positioned; c. The middle driving device is started so that a pair of pressure heads in each group of clamping modules move toward each other to perform transverse positioning on the workpiece; d. After the longitudinal and transverse positioning is completed, the clamping driving device under each group of clamping modules is started so that each pressure head is synchronously lowered to clamp the workpiece; e. After the workpiece is welded, the clamping driving device is first started to release the pressure head, and then the centering driving device moves in the direction to release the transverse unit of the workpiece, and then the workpiece is unloaded; f. When the anti-deformation welding fixture device is not used as a fixture, the multiple clamping modules in the main frame are lowered so that each pair of pressure heads on the clamping die is lower than the panel, and the fixture device can be used as a production platform.

[0033] In step a, the welding fixture device includes a main frame, and a plurality of clamping modules are arranged in sequence in the main frame. Each clamping module forms a whole through a connecting rod, and one end of the connecting rod is connected to a middle driving device arranged in the main frame; each clamping module includes a group of symmetrically arranged liftable pressure heads, and a panel is provided on the surface of the main frame, and a groove matching the pressure head is provided on the panel, and a longitudinal positioning block matching the position of the clamping module is provided on the panel.

[0034] A fixed longitudinal guide rail is provided in the main frame, and each clamping module includes a group of symmetrically arranged transverse slide grooves, each transverse slide groove is provided with a transverse slider that can slide along the transverse slide groove, and the lower part of each transverse slide groove is respectively connected to a clamping drive device, and a pressure head is embedded in each transverse slide groove, and the pressure head and the transverse slider are respectively connected to the clamping drive device. A slidable longitudinal slider is provided on the longitudinal guide rail, and the longitudinal slider and the transverse slider are connected by a group of hinge rods, so that a rotatable connection is formed between the hinge rod and the longitudinal slider, and between the hinge rod and the transverse slider, and adjacent longitudinal sliders are connected by connecting rods. The two pressure heads of each clamping module are arranged in parallel, and the pressure heads are T-shaped. The two pressure heads move synchronously toward or away from each other under the action of the hinge rod to adjust the spacing distance between the two pressure heads.

[0035] Example 3

[0036] The invention discloses a T-shaped structural member anti-deformation welding fixture device, which can quickly position the T-shaped workpiece and provide sufficient clamping force to reduce the deformation of the workpiece during the welding process. It can also be used as an ordinary workbench and has the advantages of simple structure, high clamping efficiency, large clamping force, and multiple uses.

[0037] The longitudinal slide block of each clamping module 5 is connected into a whole by a connecting rod 6 and finally connected to the movable part of the centering drive device 7;

[0038] The longitudinal slider 9 can slide on the longitudinal track, and the transverse slider 12 can slide in the transverse slot 13. The longitudinal slider 9 and the transverse slider 12 are connected by a hinge rod 10, and the hinge rod and the longitudinal slider 9 and the transverse slider 12 can rotate. The clamping drive device 14 is installed on the transverse slider 12, and the pressure head 11 is installed on the movable part of the clamping drive device 14. When used as a T-shaped structural fixture, the pressure head 11 is higher than the panel 3. When placing the workpiece, the pressure head 11 can be used as a horizontal reference for placing the workpiece. At the same time, the panel 3 is designed with corresponding notches according to the size of the pressure head 11, which can allow the pressure head 11 to drop below the panel.

[0039] When clamping, the longitudinal positioning block 4 is used for longitudinal positioning, and the pressure head 11 is used for centering positioning; the side of the pressure head is used for centering positioning of the workpiece, and the upper plane is used for clamping;

[0040] The thickness of the workpiece that the device is compatible with is determined by the stroke of the pressing drive device 14, and the width of the workpiece that the device is compatible with is determined by the stroke of the centering drive device 7.

[0041] It can be seen that the T-shaped workpiece can be positioned quickly and sufficient clamping force can be provided to reduce the deformation of the workpiece during the welding process. At the same time, it can also be used as an ordinary workbench and has multiple uses.

[0042] When in use, first place the workpiece on the panel, ensure that the workpiece is located between the two pressing heads horizontally, and longitudinally fit one end of the workpiece to the longitudinal positioning block to longitudinally position the workpiece.

[0043] Then the centering drive device is activated, and the pressure head in each clamping module performs a centering action under the action of the mechanism to position the workpiece in the horizontal direction.

[0044] like Figure 5 As shown in the figure, the longitudinal and transverse positioning is completed, and the clamping drive device is activated to clamp the workpiece. After welding is completed, the clamping device is first released, and then the centering drive device moves in the opposite direction to clear the workpiece position, and then the workpiece unloading operation is carried out. Figure 6 As shown, when the T-shaped structure is not being produced, the pressure head drops below the panel and the device can be used as other production platforms.

[0045] It should be noted that the fully described invention may also have a variety of variations and modifications, and is not limited to the specific embodiments of the above embodiments. The above embodiments are merely illustrative of the invention, not limiting thereof. In short, the scope of protection of the invention should include those variations or substitutions and modifications that are obvious to a person of ordinary skill in the art, and shall be subject to the appended claims.
