[0041] A feasible embodiment of the present application is provided below.

[0042] According to the automatic loading and unloading and vertical-horizontal conversion tooling for mechanical processing provided in the present application, a material tray 6, a truss exchange tooling 5, a vertical-horizontal turning tooling 3 and a workbench 2 are connected in sequence.

[0043] like Figure 2 As shown, the initial posture of the material tray and the truss exchange tooling 5 is a lying posture, and the initial posture of the vertical-horizontal turning tooling 3 and the workbench 2 is a standing posture. The principle is: the material tray 6 transfers the workpiece to be processed to the lying truss conversion part 5 in a lying posture, and the vertical-horizontal turning tooling 3 changes from a standing posture to a lying posture in order to achieve the handover of the workpiece, and then takes over the workpiece from the truss conversion part 5 in a lying posture, and then the vertical-horizontal turning tooling 3 is changed from a lying posture to a standing posture under the action of the driving mechanism 23 in order to hand over with the workbench 2, and finally, it is transferred to the workstation of the workbench 2 by the driving mechanism 23.

[0044] Specifically, the material tray includes: a feeding tray 6, a lifting platform and a tooling plate 7. The feeding tray 6 is arranged on the lifting platform, and the tooling plate 7 is arranged on the feeding tray 6. The tooling plate 7 is provided with a tooling plate positioning pin hole 36. Figure 3 As shown, the feeding tray 6 includes a second tray 32 and a plurality of universal bearings 33, a limit stop bar 34, and a spring push pin mechanism 35 thereon; Figure 4 As shown, the spring ejector mechanism 35 includes an ejector plate 38 , a spring guide mechanism 39 and a lower positioning pin 9 . The lower positioning pin 9 cooperates with the tooling plate positioning pin hole 36 to achieve the connection between the feed tray 6 and the tooling plate 7 .

[0045] like Figure 5 As shown, the overall structure of the truss conversion member 5 is a gantry type, and the material rack 4 can be divided into a top material rack and a bottom material rack 24, and the bottom material rack 24 can be docked with the lifting platform to exchange the tooling plate 7. The truss exchange tool 5 can complete the grabbing of the tooling plate 7 on the feeding tray 6 and push it to the vertical and horizontal turning tool 3 in the lying state.

[0046] The truss conversion member 5 includes: a pushing mechanism 27, a material rack 4 and a truss guide rail 25. The pushing mechanism 27 specifically includes: a pushing bracket 28, a pushing cylinder 29, a wedge block 8 and an upper positioning pin 31.

[0047] The output end of the push cylinder 29 is connected to the push bracket 28, and the wedge 8 is connected to the push bracket 28. Figure 6 As shown, when the push cylinder 29 moves downward toward the spring push mechanism 35, it will drive the push bracket 28 to move downward together, and then drive the wedge block 8 located on the push bracket 28 to move downward until it generates an interaction force with the spring push mechanism 35. The spring push mechanism 35 is subjected to the downward force of the wedge 8, so that the latch connection between the feed tray 6 and the tooling plate 7 is separated. Since the upper positioning pin 31 on the push bracket 28, the tooling plate positioning pin hole 36 and the lower positioning pin 9 on the feed tray 6 are in a straight line and can be effectively connected, when the lower positioning pin 9 is separated from the tooling plate positioning pin hole 36, the upper positioning pin 31 cooperates with the tooling plate positioning pin hole 36 to complete the separation of the feed tray 6 from the tooling plate 7 and the connection with the truss exchange tool 5. Through the reset of the push cylinder 29, the tooling plate 7 reaches the top rack. The truss guide rails 25 are located on both sides of the top rack and are used to convey the tooling plate 7 to the vertical and horizontal turning tool 3. Through the top crossbeam driving mechanism 26, the tooling plate 7 is transferred to the vertical-horizontal turning tooling 3 in a lying position.

[0048] Specifically, in this embodiment, Figure 7As shown, the flip frame is the main body of the vertical and horizontal flip tooling 3, and forms a T-shaped structure with the flip hinge base 11. The flip frame as a whole can rotate around the driving screw 12, and the flip frame and the driving screw 12 are connected through the screw nut mechanism 13. The driving screw 12 is connected to the driving base. The flip frame is provided with an anti-overturning wheel set 15, a supporting wheel set 16, a bearing seat 17, a lifting bar 18, a side jacking cylinder mechanism 19, a cylindrical guide rail 22, an oil and gas quick plug mechanism, a cylinder tensioning mechanism 21 and a positioning mechanism 14.

[0049] For the tooling plate 7 transmitted to the vertical and horizontal turning tooling 3, it must first pass through the bottom guidance of the cylindrical guide rail 22 and the top guidance of the anti-overturning wheel group 15 to complete the positioning of the workpiece transmission; secondly, the driving mechanism 23 is used for conveying drive to perform positioning in the direction of movement; finally, the workbench 2 is tightened by using multiple sets of cylinder tensioning mechanisms 21, and the workbench 2 is pressed onto the cylindrical guide rail 22 to complete the positioning in the up and down directions.

[0050] The vertical and horizontal turning tooling 3 is connected to the tooling plate 7 of the truss exchange tooling 5 through the connecting guide rail.

[0051] The vertical and horizontal turning tooling 3 can be connected to the truss exchange tooling 5 in a horizontal position, and can also be used to interchange the workbench 2 in a vertical position.

[0052] The vertical and horizontal turning tooling 3 can be turned from a standing position to a lying position. In the lying position, the workbench 2 is seated on the supporting wheel set 16 to complete the positioning in the upper and lower directions of the lying position. In this way, the positioning of the workbench 2 in three directions on the vertical and horizontal turning tooling 3 is completed to ensure the mechanical consistency of the docking.

[0053] The workbench 2 consists of a workbench body and a limit block 42 on the front, a disc spring cylinder 43, a rotating cylinder 44, an oil and gas quick-connect motherboard 45 on the back, a square pin hole 46 and a bottom guide wheel group 47.

[0054] During loading, the vertical and horizontal turning tool 3 is kept in a vertical position by the driving assembly 23, and the tooling plate 7 is transferred by the cooperation of the cylindrical guide rail 22 and the guide wheel group 47 of the workbench 2. The transfer movement displacement is constrained by the limit block 42. The clamping / releasing of the tooling plate 7 is achieved by controlling the disc spring cylinder 43.

[0055] When unloading, the vertical-horizontal turning tooling 3 is kept in a lying position by the driving assembly 23. After the workbench 2 is positioned on the lying vertical-horizontal turning tooling 3 in three directions, the oil and gas quick-insert mechanism on the vertical-horizontal turning tooling 3 is pushed out to complete the connection of the oil and gas pipelines. At this point, the oil cylinder and pneumatic system on the side of the workbench 2 are connected to the control system.

[0056] During operation, the array of jacking bars 18 on both sides of the horizontal position vertical and horizontal turning tooling 3 are lifted up, and the horizontal position vertical and horizontal turning tooling 3 contains universal bearings 33. In the lifted state, the universal bearings 33 on the side of the vertical and horizontal turning tooling 3 and the universal bearings 33 on the side of the truss exchange tooling 5 are in the same horizontal plane.

[0057] The disc spring cylinder 43 on the workbench 2 is fully lifted, and the rotary cylinder 44 is rotated to a horizontal posture. The truss exchange tool 5 side pushes the work plate to the vertical and horizontal flipping station on the horizontal plane. At this point, the truss exchange tool 5 completes the action.

[0058] After the tooling plate 7 is on the workbench 2, it needs to be positioned in three directions. First, the rotating cylinder 44 moves to push the tooling plate 7 onto the limit block 42 to complete the positioning in this direction; the upper side jacking cylinder mechanism 19 of the vertical and horizontal turning tooling 3 pushes the tooling plate 7 to the positioning support on the workbench 2 in this direction to complete the positioning in this direction; after positioning in two directions, the lifting bar 18 on the vertical and horizontal turning tooling 3 drops the lifted tooling plate 7 to the contact surface of the workbench 2, and now the positioning in three directions is completed.

[0059] The control oil circuit releases the pressure of the disc spring cylinder 43 on the workbench 2, and the disc spring cylinder 43 locks the tooling plate 7 to the workbench 2 by mechanical energy, thereby completing the fixing action of the workbench 2 to the tooling plate 7.
