Technical Field

[0001] This invention relates to the technical field of tooling positioning, clamping and quick-change devices, and particularly to a method of using a tooling positioning, clamping and quick-change device for a workstation. Background Technology

[0002] Robotic automated welding workstations have significantly improved production conditions, increased production efficiency, and enhanced welding quality, leading to their increasingly widespread application in the industrial welding field. These welding robots are often used in conjunction with positioners to achieve omnidirectional, dead-angle-free welding.

[0003] Currently, tooling loading and unloading on positioners in the market mostly rely on forklifts, and tooling positioning is achieved through locating pins. This method requires a sufficiently large operating space, is difficult and cumbersome to operate, time-consuming, labor-intensive, and inefficient. Therefore, to address these issues, our company has developed a tooling positioning, clamping, and quick-change device. This device enables rapid switching of tooling loading and unloading within the limited space of the workstation, offering fast and high-precision positioning, easy operation, and a high degree of automation. It effectively shortens tooling loading and unloading time and significantly improves work efficiency.

[0004] Existing tooling is mostly loaded and unloaded using forklifts, which makes positioning difficult and places high demands on space and operation.

[0005] The existing tooling positioning is achieved through positioning pins, but the process of installing and removing positioning pins is cumbersome, time-consuming, and labor-intensive.

[0006] Currently, the tooling loading and unloading on positioners in the market is mostly done by forklifts, and tooling positioning is achieved by positioning pins.

[0114] The locking rod 74 has one end slidably connected to the other end of the guide rod 84, and the other end of the locking rod 74 is rotatably connected to the other end of the mounting base 81. A protrusion is provided on one end of the locking rod 74, which can be operated to abut against the bottom of the tooling frame 1 and prevent the tooling frame 1 from moving.

[0115] In a further embodiment of the present invention, the specific implementation method is as follows, such as... Figure 1 As shown, after the tooling frame 1 is placed on the quick-change trolley 2, the check mechanism 22 locks the tooling frame 1 in a fixed position. The quick-change trolley 2 is guided and pushed into the workstation by the steering mechanism 3 and guide wheels 24. Then, the lifting mechanism 5 lifts the tooling frame 1 to a position level with the positioning and clamping mechanism 11. At this point, the check mechanism 22 is released, and the tooling frame 1 is pushed along the direction of the universal ball 25 and guide wheels 26 until it reaches the abutment position on the positioning and clamping mechanism 11. Figure 3 As shown, the tooling frame 1 has a track groove below its legs, which is positioned above the universal ball joint 25 of the quick-change trolley 2. The side of the tooling frame 1 support is tangent to the guide wheel 26 of the quick-change trolley 2. The quick-change trolley 2 achieves relative linear movement with the tooling frame 1 through the rotation of the universal ball joint 25 and the guide wheel 26. Figure 4 As shown, by rotating the steering handwheel 31, the driving bevel gear drives the driven bevel gear to rotate. The driven bevel gear drives the front steering wheel 23 to rotate via the rotating shaft 86. At the same time, the bevel gear set 87 above the front steering wheel 23 rotates, which in turn drives the rear steering wheel 23 to rotate via the rotating shaft 86, and the bevel gear set 87 above it also rotates, thus realizing the synchronous steering function of the front and rear wheels. When the tooling frame 1 is placed directly above the quick-change trolley 2, the driving wrench 88 is released, and the driven clamping plate 89 pops out under the action of the spring 9, together with the fixed baffle 43, fixing one of the supports of the tooling frame 1, as shown. Figure 7 As shown; when it is necessary to separate the tooling frame 1 from the quick-change trolley 2, pull back the driving wrench 88 forcefully, causing the driven clamp 89 to retract against the force of the spring 9. After the clamp 89 retracts, the support of the tooling frame 1 is released, and the two can then perform relative linear motion, as shown. Figure 8 As shown; the guide wheel 24 on the quick-change trolley 2 cooperates with the guide plate 41 to allow the quick-change trolley 2 to enter the workstation in the correct direction. After the impact block 82 at the end of the quick-change trolley 2 hits the baffle 43, the PLC-controlled cylinder 44 pushes the clamping block 14 to press the impact block 82 of the quick-change trolley 2. At this time, the quick-change trolley 2 is clamped and fixed. When the quick-change trolley 2 is not in position (i.e., not in the workstation), the state of the top pin 83 is as follows. Figure 11 As shown: At this time, the left end of the top pin 83 is not under force, the spring 9 lifts the guide rod 84 and the locking rod 74, and the tooling frame 1 is locked by the locking rod 74 and cannot be pushed out, thus achieving locking; when the trolley is placed (i.e., enters the workstation), the state of the top pin 83 is as follows. Figure 12As shown: At this time, the impact block 82 hits the end face of the positioning and clamping mechanism 11, and the top pin 83 retracts to the right after being forced, pushing the right end of the guide rod 84 downward, causing the locking rod 74 head to move downward (i.e., the limit switch fails). At this time, the tooling frame 1 can be pushed out; the positioner side air pipe mounting plate 61 is placed on the positioning and clamping mechanism 11, and the fixture side air pipe mounting plate 62 is placed on the tooling frame 1, as shown. Figure 13 As shown, after the tooling frame 1 is in place, manually push the push-pull rod 72. Guided by the guide block 7 and the guide shaft 63, accurately insert the insertion tube 64 into the air pipe connector 67. At the same time, insert the current plug into the first current plug socket 65 and the second current plug socket 66. After tightening, pull the locking rod 74 to the eccentric positioning pin 73 to lock the device. Figure 14 As shown; at this time, the air and electrical circuits connected to the positioning and clamping mechanism 11 are connected to the tooling, that is, the tooling is ventilated and energized; one side of the driving mechanism 111 or the driven mechanism 112 is connected to the driving (driven) end flange on the positioner, and the other side is engaged with the tooling frame 1; when the tooling frame 1 is not in place, the connecting rod cylinder 15 is in the extended state, and the positioning block 13 and the clamping block 14 are pulled up through the first connecting rod mechanism 16 and the second connecting rod mechanism 17 so that the tooling frame 1 can move in and out, as shown. Figure 15 As shown; when the tooling frame 1 enters the pin position (falls into the workstation) and the pneumatic quick-connect mechanism 6 is inserted, the PLC controls the linkage cylinder 15 to tighten, which in turn drives the first linkage mechanism 16 and the second linkage mechanism 17 to straighten. The positioning block 13 and the clamping block 14 fall into the designated position on the upper surface of the tooling frame 1, realizing positioning and clamping; at the same time, the follower rod 18 pulls the support rod 19 upward, so that the tooling frame 1 is subjected to an upward lifting force, thereby realizing the clamping of the upper and lower surfaces of the tooling frame 1, as shown. Figure 16 As shown, the tooling loading process has now been completed, and the unloading process is the reverse of the operation sequence.
