The clamping tool for welding the hydraulic telescopic arm shell of the invention will be clearly and completely described below with reference to the accompanying drawings.
As shown in fig. 1 to 3, the invention provides a clamping tool for welding a hydraulic telescopic arm shell, which comprises a mounting plate 1, an upper clamping jaw 2 and a lower clamping jaw 3 which are slidably connected to one side of the mounting plate 1, a vertical driving mechanism for driving the upper clamping jaw 2 and the lower clamping jaw 3 to move to clamp and fix the hydraulic telescopic arm shell 100, and a lateral clamping jaw group 5 which is slidably connected to the free end of the lower clamping jaw 3 and is used for centering, positioning and clamping the hydraulic telescopic arm shell 100 before clamping and fixing the hydraulic telescopic arm shell 100.
Specifically, the mounting plate 1 is arranged on a positioner, is driven by the positioner to rotate, and is provided with two mounting plates which are respectively arranged at a fixed end and a movable end of the positioner; two one side that mounting panel 1 is relative all is equipped with clamping jaw 2, lower clamping jaw 3, vertical actuating mechanism and side direction clamping jaw group 5.
Vertical actuating mechanism sets up to vertical straight line module 4, and its fixed mounting is in on the mounting panel 1, go up 2 sliding connection of clamping jaw in the upper end of vertical straight line module 4, lower clamping jaw 3 sliding connection be in the lower extreme of vertical straight line module 4, just the length of clamping jaw 3 is greater than down the length of going up clamping jaw 2 for when the material loading, the work piece can be followed the top and dropped on clamping jaw 3 down, and does not receive go up the interference of clamping jaw 2.
Horizontal straight line module 6 is installed to the free end tip of lower clamping jaw 3, side direction clamping jaw group 5 with horizontal straight line module 6 sliding connection, it by horizontal straight line module 6 drive carries out centering positioning to the work piece and presss from both sides tightly. Specifically, a distance sensor 7 is installed on one side, opposite to the workpiece, of one clamping jaw in the lateral clamping jaw group 5, so that a central control system can regulate and control the movement distance of the lateral clamping jaw group 5 to center, position and clamp the workpiece; meanwhile, the clamping degree of the lateral clamping jaw group 5 to the workpiece can be adjusted by detecting the movement distance of the lateral clamping jaws, so that the workpiece is prevented from being deformed or damaged.
In addition, still be equipped with pushing equipment 8 in this device, its symmetric distribution is in go up the left side and the right side of clamping jaw 2, include: a pusher cylinder 81 and a pusher plate 82. The material pushing cylinder 81 is arranged on the mounting plate 1 and is arranged on the same side as the upper clamping jaw 2; the end part of the driving end is fixed with a connecting frame 83 through a bolt, and the material pushing plate 82 is arranged at the end part of the free end of the connecting frame 83. Specifically, the connecting frame 83 is configured to be an inverted "L" shape. And the material pushing mechanism 8 is used for pushing the workpiece to move so that the workpiece reaches a clamping position or pushing the workpiece to move for blanking.
Specifically, in this embodiment, the lower surface of the upper clamping jaw 2 is provided with a flexible mechanism 9, which includes an expansion link 91, a rubber plate 92 fixed to the end of the free end of the expansion link 91, and a cylindrical spring 93 sleeved outside the expansion link 91; through setting up flexible mechanism 9, can further avoid the work piece to take place to warp or damage at the tight degree of clamp of tight in-process elasticity regulation and control to the work piece.
The working principle of the invention is as follows:
after a workpiece is hoisted above the positioner in a balanced manner by utilizing the hanging strip, the moving end of the positioner moves backwards to a proper position, and the workpiece can fall onto the lower clamping jaw 3 from the top without interfering with the upper clamping jaw 2 because the upper clamping jaw 2 is shorter than the lower clamping jaw 3, and the workpiece is in a plane position and is not a welding surface when being contacted with the upper clamping jaw 2 and the lower clamping jaw 3.
After the workpiece is hoisted in place, the horizontal linear module 6 is started to move, so that the lateral clamping jaw groups 5 at the two ends of the positioner clamp the side face of the workpiece, in the process, the distance sensor 7 is used for detecting the movement distance of the lateral clamping jaw groups 5, and then a signal is sent to the central control system to regulate and control the clamping degree of the workpiece, and the situation that the workpiece is abnormally deformed or damaged is avoided. When the lateral centering clamping is finished, the lateral clamping jaw set 5 is released.
Then starting the moving end of the positioner to move towards the fixed end of the positioner, pushing the workpieces to move together after a material pushing plate 82 on the positioner contacts the workpieces, and stopping the workpieces when the workpieces move to a preset clamping position; at the moment, the horizontal linear module 6 is started to drive the lateral clamping jaw set 5 to clamp the side face of the workpiece. In the process, the distance sensor 7 is used for detecting the movement distance of the lateral clamping jaw group 5, and then a signal is sent to the central control system to regulate and control the clamping degree of the workpiece, so that the situation that the workpiece is abnormally deformed or damaged is avoided, and the clamping reliability is ensured.
After the lateral clamping jaw set 5 is automatically clamped, the vertical linear module 4 is started to drive the upper and lower clamping jaws 3 to clamp the upper and lower surfaces of the workpiece, the workpiece is prevented from generating abnormal deformation or damage through elastic regulation and control of the flexible mechanism 9 in the clamping process, and the clamping reliability is ensured.
When all the clamping jaws are automatically clamped in place, the positioner starts to rotate to drive the workpiece to rotate until the welding surface of the workpiece is in a horizontal state, so that welding operation is performed. And after one side welding seam is finished, the positioner rotates 180 degrees, and the welding work of a second welding seam is continuously finished.
After all weldment work were accomplished to the work piece, the workman master utilizes the suspender to hold the work piece from the below, carries out supplementary lifting, guarantees safety, then starts vertical straight line module 4 with horizontal straight line module 6 reverse motion in proper order to release the work piece.
And then, starting the moving end of the positioner to move a certain distance in the direction far away from the fixed end of the positioner, and starting a material pushing mechanism 8 at the fixed end of the positioner to push the workpiece to move, so that the workpiece avoids the edge of the upper clamping jaw 2, and a certain blanking safety distance is reserved for blanking.
After the blanking process is finished, the positioner is adjusted to a feeding preparation position, and meanwhile, the pushing mechanisms 8 at the two ends and the upper and lower clamping jaws 3 are returned to the original positions to wait for feeding of the next workpiece.
According to the invention, the hydraulic telescopic arm shell 100 is positioned and clamped by arranging the upper clamping jaw 3, the lower clamping jaw 3, the vertical driving mechanism and the lateral clamping jaw group 5, so that the structure is simple and the operation is convenient; and can carry out accurate centering location to utilizing two sets of side direction clamping jaw group 5 to it before pressing from both sides tight to hydraulic telescoping arm shell 100 to can avoid appearing pressing the condition of telescopic arm offset, and then can guarantee welding quality.
Meanwhile, the lateral clamping jaw group 5 is directly arranged at the end part of the lower clamping jaw 3 to center, position and clamp the workpiece, so that compared with the traditional clamp, the whole structure of the clamp is simplified, the assembly is convenient, and the production cost is low; meanwhile, when longer workpieces such as the hydraulic telescopic arm shell 100 and the like are clamped, the operation is more flexible and convenient.
