[0002] Construction machinery seats are specially designed for various types of construction machinery. They aim to provide drivers with a comfortable riding experience and a safe operating environment. They usually have a sturdy structure, adjustable functions and durable materials to adapt to harsh working conditions. The seat bracket is one of the most important mechanical metal material components of construction machinery seats. It is responsible for providing the basic structure and support of the seat, ensuring the stability and safety of the seat. The seat bracket is currently usually welded from two guide rails and a metal connecting rod.

[0003] The existing welding of guide rails and connecting rods is usually performed by first fixing and fitting a connecting rod to a guide rail through a pneumatic clamp, and then welding, and then fixing and welding the other guide rail after the welding is completed.

[0034] like Figure 1 , Figure 2 and Figure 4 As shown, the fixing mechanism 2 includes a stepper motor 20, and the stepper motor 20 is fixedly installed on the right end of the vertical section of the support plate 11, and the output shaft of the stepper motor 20 rotates and passes through the support plate 11 and then fixedly installed with a fixing plate 21, and the left end of the fixing plate 21 is fixedly installed with an H-shaped plate 22, and two front-to-back symmetrical bottom plates 23 are fixedly installed on the upper end of the right longitudinal section of the H-shaped plate 22, and the bottom plate 23 is L-shaped structure, and two No. 1 supports 24 for limiting support to the longitudinal section of the connecting rod are fixedly installed front-to-back symmetrically on the upper end of the left longitudinal section of the H-shaped plate 22, and two No. 2 supports 25 for limiting support to the two horizontal sections of the connecting rod are fixedly installed front-to-back symmetrically on the upper end of the left longitudinal section of the H-shaped plate 22, and U-shaped grooves are provided on the upper ends of the No. 1 support 24 and the No. 2 support 25.

[0035] like Figure 1 and Figure 2 As shown, the base plate 23 is provided with a No. 1 fixing portion 26 for fixing the guide rail and a No. 2 fixing portion 27 for fixing the connecting rod, the H-shaped plate 22 is provided with a pushing portion 28 for pushing the connecting rod to fit the guide rail, and the H-shaped plate 22 is also provided with a driving portion 29 for driving the No. 1 fixing portion 26, the No. 2 fixing portion 27 and the pushing portion 28.

[0036] During the specific work, the two guide rails are manually placed on the upper end surfaces of the horizontal sections of the two base plates 23, and the right end of the guide rail is pushed to contact the left end of the fixed plate 21. Then the connecting rod is placed on the No. 1 support 24 and the No. 2 support 25, and the connecting rod is pre-limited by the U-shaped grooves on the No. 1 support 24 and the No. 2 support 25. Then the driving part 29 drives the No. 1 fixing part 26 to extrude and fix the guide rail, and the No. 2 fixing part 27 to extrude and fix the connecting rod. At the same time, the pushing part 28 pushes the connecting rod to correct the fit with the guide rail, thereby improving the fit between the connecting rod and the guide rail, and then improving the quality of the guide rail and the connecting rod after welding.

[0037] Then the welding mechanism 3 moves down to weld the fitting part of the connecting rod and the guide rail. After the welding is completed, the welding mechanism 3 moves up away from the guide rail and the connecting rod. Then the stepper motor 20 drives the fixed plate 21, the H-shaped plate 22 and the fixed connecting rod and the guide rail to rotate 180 degrees. Then the welding mechanism 3 moves down again to weld the other side of the fitting part of the connecting rod and the guide rail. After the welding of the two places is completed, the stepper motor 20 drives the fixed plate 21, the H-shaped plate 22 and the fixed connecting rod and the guide rail to rotate 180 degrees to reset. Then the No. 2 fixing part 27 and the pushing part 28 release the limiting extrusion on the connecting rod, and the No. 1 fixing part 26 releases the fixation of the guide rail. Then the guide rail and the connecting rod are replaced, and the above operations are repeated to continue the welding process of the guide rail and the connecting rod.

[0038] like Figure 2 , Figure 4 and Figure 5 As shown, the No. 1 fixing portion 26 includes an extrusion plate 260, and the upper end of the horizontal section of the base plate 23 is slidably installed with an extrusion plate 260, and the upper end of the H-shaped plate 22 is slidably installed with two front-to-back symmetrical slide plates 261, and the upper end of the H-shaped plate 22 is fixedly installed with a No. 1 support plate located between the two slide plates 261, and a No. 1 compression spring 262 is fixedly installed between the No. 1 support plate and the corresponding slide plate 261, and the opposite ends of the two slide plates 261 slide through the corresponding base plate 23, and the opposite ends of the two extrusion plates 260 are fixedly connected to the corresponding slide plates 261 through a connecting plate 263, and a lower pressing piece 4 for extruding the guide rail from bottom to bottom is provided on the extrusion plate 260.

[0039] like Figure 2 , Figure 4 and Figure 6 As shown, the No. 2 fixing portion 27 includes a limiting component, and a limiting component is arranged on the right side of the No. 2 support 25. Each group of limiting components is composed of two clamping blocks 270 that are symmetrical front and back. The opposite surfaces of the two clamping blocks 270 in the same group are provided with No. 1 V-shaped grooves, and the lower end of each clamping block 270 is symmetrically fixed with two guide columns 271. Waist grooves are arranged at positions corresponding to the guide columns 271 on the H-shaped plate 22, and the lower ends of the guide columns 271 slide through the corresponding waist grooves.

[0040] like Figure 2 and Figure 3 As shown, the pushing portion 28 includes an L-shaped plate 280, and two L-shaped plates 280 that are symmetrical front to back and located on the right side of the limiting assembly are slidably installed on the upper end of the H-shaped plate 22, and the opposite ends of the vertical sections of the two L-shaped plates 280 are fixedly installed with pushing blocks 281, and the opposite sides of the two pushing blocks 281 are provided with No. 2 V-shaped grooves, and the upper end of the H-shaped plate 22 is fixedly installed with a No. 2 support plate located between the two L-shaped plates 280, and a No. 2 tension spring 282 is fixedly installed between the No. 2 support plate and the L-shaped plate 280.

[0041] like Figure 2 , Figure 4 and Figure 7 As shown, the driving part 29 includes a T-shaped plate 290, the upper end of the H-shaped plate 22 is slidably mounted with the T-shaped plate 290, the upper end of the H-shaped plate 22 and located on the left side of the T-shaped plate 290 is fixedly mounted with a No. 3 electric push rod 291, the telescopic section of the No. 3 electric push rod 291 is fixedly connected to the left end of the T-shaped plate 290, the upper end of the horizontal section of the L-shaped plate 280 is fixedly mounted with a No. 1 push block 292, the No. 1 push block 292 is a right-angled trapezoidal structure with an inclined surface away from the T-shaped plate 290 and the slide plate 261, and the upper end of the slide plate 261 is fixedly mounted with a No. 2 push block 293, the second pushing block 281 is a right-angled trapezoidal structure with an inclined surface close to the T-plate 290 and the L-plate 280, the longitudinal section of the T-plate 290 is fixedly installed with a No. 1 inclined block 294 corresponding to the No. 1 push block 292, and the transverse section of the T-plate 290 is fixedly installed with a No. 2 inclined block 295 corresponding to the No. 2 push block 293. Both the No. 1 inclined block 294 and the No. 2 inclined block 295 are right-angled trapezoidal structures. The T-plate 290 is provided with a locking assembly for limiting the rotation of the fixed plate 21 and an actuator 6 for driving the clamping block 270 to move.

[0042] like Figure 2 , Figure 4 and Figure 6 As shown, the actuator 6 includes a rectangular plate 60, the rectangular plate 60 is fixedly installed on the lower end of the T-plate 290, a slide groove is opened at a position corresponding to the rectangular plate 60 on the H-plate 22, the rectangular plate 60 slides through the slide groove, and a driving plate 61 located on the left side of the rectangular plate 60 is slidably installed at the lower end of the H-plate 22, and a No. 3 tension spring 62 is fixedly installed between the right end of the driving plate 61 and the left end of the rectangular plate 60, and an inclined groove 63 is opened at a position corresponding to the guide column 271. The inclined grooves 63 that are opposite to each other and cooperate with the two guide columns 271 on the same clamping block 270 are combined to form an eight-shaped structure with a small left and a large right.

[0043] During specific operation, the No. 3 electric push rod 291 pushes the T-shaped plate 290 to move rightward, and the T-shaped plate 290 contacts the No. 2 push block 293 through the No. 2 inclined block 295 to push the two slide plates 261 closer to each other and compress the No. 1 compression spring 262. The slide plate 261 drives the corresponding extrusion plate 260 to squeeze the corresponding guide rail through the connecting plate 263, so that the guide rail contacts the vertical section of the corresponding bottom plate 23, and the guide rail is limited by the extrusion of the extrusion plate 260. In the process of moving the extrusion plate 260, the lower pressing piece 4 will also be driven to squeeze the guide rail from bottom to bottom to ensure the parallelism of the guide rail, thereby improving the welding accuracy. In the process of moving the T-shaped plate 290, the driving plate 61 will be pulled to the right through the rectangular plate 60 and the No. 3 tension spring 62 Move, the driving plate 61 drives the two clamping blocks 270 of the same group to move closer to each other through the cooperation of the inclined groove 63 and the guide column 271 to clamp and fix the connecting rod. At the same time, the No. 1 inclined block 294 will push the No. 1 pushing block 292 to make the two L-shaped plates 280 move away from each other and stretch the No. 2 tension spring 282. The L-shaped plate 280 drives the corresponding pushing block 281 to push the connecting rod to ensure the fit between the connecting rod and the guide rail. In addition, the No. 2 V-groove on the pushing block 281 can extrude and correct the connecting rod to further ensure the strength and quality of the welding between the connecting rod and the guide rail. Then the No. 3 electric push rod 291 pushes the T-shaped plate 290 to move further to the right, so that the locking assembly cooperates with the support plate 11 to improve the stability of the H-shaped plate 22.

[0044] When welding is completed, the No. 3 electric push rod 291 pulls the T-shaped plate 290 to move to the left, the No. 1 inclined block 294 moves away from the No. 1 push block 292, and the No. 2 inclined block 295 moves away from the No. 2 push block 293, and the drive plate 61 moves to the left under the action of the No. 3 tension spring 62, thereby releasing the fixation of the guide rail and the connecting rod, and then the welded connecting rod and guide rail can be removed.

[0045] like Figure 4 and Figure 5 As shown, the lower pressure member 4 includes a movable groove, and two movable grooves are symmetrically opened at the upper end of the extrusion plate 260. A rotating shaft 40 is rotatably installed on the extrusion plate 260, and the rotating shaft 40 passes through the two movable grooves. Fixed blocks 41 are fixedly installed at positions corresponding to the movable grooves on the rotating shaft 40, and an inverted plate 42 is fixedly installed at one end of the fixed block 41 away from the corresponding extrusion plate 260. A lower pressure plate 43 is fixedly installed below the horizontal section and below the two vertical sections of the inverted plate 42 through No. 2 compression springs 44. A pillar that slides through the inverted plate 42 is fixedly installed on the upper end of the lower pressure plate 43. A rotating member 5 for driving the rotating shaft 40 to rotate is provided on the extrusion plate 260.

[0046] like Figure 4 and Figure 5As shown, the rotating member 5 includes a T-shaped column 50, and two T-shaped columns 50 are symmetrically arranged at the opposite ends of the two extrusion plates 260. The horizontal sections of the two T-shaped columns 50 on the same extrusion plate 260 slide through the corresponding extrusion plates 260 and are fixedly installed with a support plate 51. A No. 1 tension spring 52 is fixedly installed between the vertical section of the T-shaped column 50 and the corresponding extrusion plate 260. A slot is provided at the upper end of the extrusion plate 260 corresponding to the support plate 51. A spur gear 53 located in the slot is fixedly installed on the rotating shaft 40, and a rack 54 is meshed with the lower part of the spur gear 53, and the rack 54 is fixedly connected to the corresponding support plate 51.

[0047] During specific operation, when the extrusion plate 260 moves toward the guide rail and pushes the vertical sections of the guide rail to fit together with the base plate 23, the guide rail is restricted from further movement due to the fit between the vertical sections of the guide rail and the base plate 23. As a result, as the extrusion plate 260 moves, it pushes the push plate 51 to move toward the spur gear 53 and stretches the No. 1 tension spring 52. The base plate 23 drives the rotating shaft 40 to rotate through the meshing of the rack 54 and the spur gear 53. The rotating shaft 40 drives the inverted plate 42 to rotate toward the guide rail through the fixed block 41, so as to extrude and fix the moving part and the fixed part of the guide rail through the lower pressure plate 43 to ensure the stability of subsequent welding and rotation, as well as the parallelism of the guide rail.

[0048] When the extrusion plate 260 moves away from the guide rail to release the fixation of the guide rail, the No. 1 tension spring 52 will push the push plate 51 to move away from the corresponding extrusion plate 260, and the push plate 51 will drive the rotating shaft 40 to rotate in the opposite direction through the cooperation of the rack 54 and the spur gear 53, so that the lower pressure plate 43 rotates away from the guide rail to facilitate the taking and placing of the guide rail.

[0049] like Figure 2 and Figure 3 As shown, the welding mechanism 3 includes an electric push rod No. 1 30, and the upper end of the horizontal section of the support plate 11 is fixedly installed with the electric push rod No. 1 30. The telescopic section of the electric push rod No. 1 30 slides through the support plate 11 and is fixedly installed with a receiving plate 31. The receiving plate 31 is slidably installed on the left end of the vertical section of the support plate 11, and the lower end of the receiving plate 31 is slidably installed with a connecting plate 32, and the lower end of the connecting plate 31 is fixedly installed with two front-to-back symmetrical welding components 33, and the lower end of the receiving plate 31 is fixedly installed with a No. 2 electric push rod 34 located on the right side of the connecting plate 32, and the telescopic section of the No. 2 electric push rod 34 is fixedly connected to the right end of the receiving plate 31.

[0051] During specific operation, after the connecting rod and the guide rail are fixed, the No. 1 electric push rod 30 pushes the receiving plate 31 downward, and the receiving plate 31 drives the welding assembly 33 to move toward the joint of the connecting rod and the guide rail until it moves to the effective distance required for welding. The No. 2 electric push rod 34 drives the two welding assemblies 33 to move left and right through the connecting plate 32 to weld the joint of the connecting rod and the guide rail. After the welding is completed, the No. 1 electric push rod 30 pulls the welding mechanism 3 to move up and reset, and then the No. 3 electric push rod 291 pulls the T-plate 290 to move a certain distance to the left until the limit column 296 is separated from the support Plate 11, and the No. 1 fixing part 26, the No. 2 fixing and pushing part 28 maintain the limit of the guide rail of the connecting rod, and then the stepper motor 20 drives the fixing plate 21, the H-type plate 22 and the fixed connecting rod and the guide rail to rotate 180 degrees, and then the No. 3 electric push rod 291 pushes the T-type plate 290 to move right back, and the T-type plate 290 drives the limiting column 296 to insert into the support plate 11 to further limit the movement of the fixing plate 21, thereby further improving the stability of the welding between the connecting rod and the guide rail, and then the welding mechanism 3 moves down again to perform welding processing operations on the fitting part of the connecting rod and the guide rail after rotation.
