Description

Technical Field

[0001] The present invention relates to the technical field of automobile manufacturing, and more specifically, to a blank station bracket for a stamping automation line. Background Art

[0002] With the increasing maturity of automation technology in the automobile manufacturing industry, major automobile manufacturers have higher and higher requirements for the production efficiency of stamping automation lines. With the application of high-speed stamping lines in major automobile manufacturers, the form of the automatic transmission mechanism has developed from the traditional parallelogram manipulator structure to a high-speed and stable single-arm or double-arm crossbar structure. To ensure the SPM of the high-speed stamping line, it is required that the stamped parts avoid rotation as much as possible during the transmission process, and the feeding heights of the front and rear processes are kept consistent.

[0003] Currently, in order to maximize the automation efficiency of the high-speed line, the structural design of the stamped parts generally requires that the feeding heights of the front and rear processes of the die are kept consistent, the rotation of the Z-axis of the parts is prohibited during the transmission process, the rotation of the X-axis is generally not allowed in principle, and the rotation angle of the Y-axis is as small as possible; at the same time, for the combined die parts of the left and right parts, if there is a need for lateral displacement in the subsequent process (that is, the relative distance between the left and right parts becomes larger), the lateral displacement function is generally integrated in the end effector and realized by using a cylinder to achieve lateral displacement during the transmission process of the parts.

[0004] In the existing technical solutions, the rotation of the stamped parts is avoided as much as possible during the transmission process, which limits the selection of stamping process plans, affects the selection of stamping directions in the drawing process, causes the main ridge line to slip and other surface quality defects that cannot be solved, especially unacceptable for outer cover parts; at the same time, it affects the trimming process arrangement of the parts, resulting in excessive burrs of the parts with excessive trimming angles or increasing the tooling cost of the trimming process. In addition, the feeding heights of the front and rear processes of the stamped parts are kept consistent during the transmission process, resulting in an increase in the height of some dies and an increase in the tooling development cost. And for the parts that need lateral displacement, the lateral displacement function is integrated in the end effector, which increases the load and movement trajectory during the movement of the end effector, affecting the automation efficiency and stability.

[0005] Therefore, how to provide a blank station bracket that can effectively solve the problems of low automation efficiency and poor stability during the lateral displacement of the combined die parts of the left and right, the rotation requirement of the stamped parts during the transmission process, and the inconsistent feeding heights of the front and rear processes of the stamped parts has become a technical problem that needs to be solved urgently in this field.

[0044] Now, various exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that: unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and values set forth in these embodiments do not limit the scope of the present invention.

[0045] The following description of at least one exemplary embodiment is merely illustrative and is in no way a limitation on the present invention, its application, or its use.

[0046] Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies, methods, and devices should be considered as part of the specification.

[0047] In all examples shown and discussed herein, any specific values should be construed as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments may have different values.

[0048] It should be noted that like reference numerals and letters denote like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof in subsequent figures is not required.

[0049] According to Figures 1 to 10 As shown, the present invention provides a blank station bracket for a stamping automation line, including a bracket base 3, a rotating mechanism 4, a bracket cross beam 5, and two rear door inner panel brackets 6.

[0050] The bracket base 3 includes a bracket mounting connecting plate 32 and a fixing plate 31. The fixing plate 31 is used to fix the bracket base 3 on the stamping equipment, and the bracket mounting connecting plate 32 is connected to the rotating mechanism 4. The bracket base 3 can be designed with different heights (mainly changing the height of the column between the fixing plate 31 and the bracket mounting connecting plate 32) to achieve a design with unequal heights for feeding in the previous and subsequent processes, thereby reducing the cost of mold development.

[0051] The middle position of the bracket cross beam 5 is connected to the rotating mechanism 4, and the rotating mechanism 4 can drive the bracket cross beam 5 to rotate circumferentially around it.

[0052] Both ends of the bracket cross beam 5 are connected with side shift mechanisms 7, and the two rear door inner panel brackets 6 are respectively connected to the side shift mechanisms 7. The side shift mechanisms 7 can respectively drive the two rear door inner panel brackets 6 to move axially, and the two rear door inner panel brackets 6 are respectively used to clamp the left rear door inner panel 1 and the right rear door inner panel 2. In implementation, the bracket cross beam 5 of the present invention corresponds to the Y-axis. By using the rotating mechanism 4, the rotational movement of the part around the Y-axis direction can be realized. By integrating the rotating structure on the blank station bracket, the rotational requirement of the stamping part during transmission can be effectively solved. By integrating the side shift function on the blank station bracket, the problems of low automation efficiency and poor stability during the side shift of the left and right mold-closing parts can be effectively solved, and the separate movement of the mold-closing parts in the Y-axis direction can be realized. At the same time, by designing brackets with different heights, the problem of inconsistent feeding heights in the front and rear processes of the stamping part can be effectively solved, thereby realizing the lean development of the tooling.

[0053] Further, the rotation mechanism 4 includes a rotation base 41, a cover plate 42, a rotation cam 44, and a rotation cylinder 43. The rotation base 41 and the cover plate 42 are snap-connected, and the bottoms of both are fixedly connected to the bracket mounting connecting plate 32. The rotation cam 44 is disposed inside the rotation base 41 and the cover plate 42, and the rotation cylinder 43 is disposed on the bracket mounting connecting plate 32. The end of its piston rod is hinged to the side wall of the rotation cam 44. An installation hole 441 is also provided in the middle of the rotation cam 44, and the middle position of the bracket cross beam 5 is connected inside the installation hole 441. During implementation, the rotation base 41 and the cover plate 42 are snap-connected, and a cavity structure is formed inside the two. The rotation cam 44 is placed inside the cavity, and the rotation cam 44 can rotate relative to the cavity. By the intake and exhaust of the rotation cylinder 43, the rotation cam 44 can be pushed to move clockwise or counterclockwise along the rotation base 41, thereby driving the bracket cross beam 5 to achieve a rotational motion.

[0054] Furthermore, the installation hole 441 is in a rectangular structure, and the bracket cross beam 5 is in a rectangular rod structure that matches the installation hole 441. Through the design of the non-circular installation hole 441, relative rotation between the bracket cross beam 5 and the installation hole 441 cannot occur, ensuring that when the rotation cylinder 43 drives the rotation cam 44 to rotate, the bracket cross beam 5 can rotate synchronously.

[0055] Furthermore, a fixing pin 45 is also provided on the inner side wall of the installation hole 441, and a pin hole corresponding to the fixing pin 45 is provided in the middle position of the bracket cross beam 5, so that the bracket cross beam 5 and the rotation cam 44 are limited and fixed by the fixing pin 45.

[0056] Furthermore, a limiting surface protrudes on the end face of the rotation cam 44. The limiting surface protrudes beyond the side walls of the rotation base 41 and the cover plate 42, and a rotation limiting plate 46 is also provided on the side wall of the cover plate 42. The rotation limiting plate 46 and the limiting surface are on the same side. When the limiting surface contacts the rotation limiting plate 46, the rotation cylinder 43 stops operating. Since the rotation requirement of the present invention for the Y-axis is relatively small, it is necessary to limit the rotation angle of the rotation cam 44 through the limiting surface and the rotation limiting plate 46.

[0057] Furthermore, the limiting surface includes a rotation upper limiting surface 442 and a rotation lower limiting surface 443. The rotation upper limiting surface 442 and the rotation lower limiting surface 443 are respectively located on the upper side and the lower side of the rotation limiting plate 46 to respectively limit the rotation angles of the counterclockwise rotation and the clockwise rotation of the rotation cam 44. The rotation mechanism 4 can change the positions of the rotation upper limiting surface 442 and the rotation lower limiting surface 443 to meet the rotation angle requirements of different parts.

[0058] Further, the side shift mechanism 7 includes a connection plug 71, a transfer rod 72, a side shift slideway 73, a side shift slider 74, and a side shift cylinder 76.

[0059] One end of the connecting plug 71 is connected to the end of the support crossbeam 5, and the other end is connected to the transfer rod 72. The side shift slideway 73 is arranged in parallel on the lower side of the transfer rod 72. The side shift slider 74 translates along the side shift slideway 73, and a support connector 77 is provided on the lower side of the side shift slider 74. The support connector 77 is used to connect the rear door inner panel support 6. The side shift cylinder 76 is arranged on the side of the connecting plug 71 through the connecting plate 75, and the piston rod of the side shift cylinder 76 is connected to the side shift slider 74. During implementation, the side shift cylinder 76 pushes the side shift slider 74 to move in the left-right direction along the side shift slideway 73, thereby driving the support body to achieve side shift movement. At the same time, the present invention can replace the model of the side shift cylinder 76 to meet the requirements of different side shift strokes.

[0060] Furthermore, the rear door inner panel support 6 includes a support main rod 61 and multiple support rods 62. The support main rod 61 is clamped inside the support connector 77, and the support rods 62 are all vertically connected to the support main rod 61. An inductor 63 is provided at the end of one of the support rods 62, and the inductor 63 is used to detect the left rear door inner panel 1 or the right rear door inner panel 2; baffles 64 are provided at the ends of the remaining support rods 62, and the baffles 64 jointly act on the clamping and fixing of the left rear door inner panel 1 or the right rear door inner panel 2.

[0061] Further, the support crossbeam 5 includes a crossbeam main rod 51 and crossbeam transition connecting plates 52. The crossbeam transition connecting plates 52 are arranged at both ends of the crossbeam main rod 51, and inwardly recessed jacks 54 are provided on the connecting plates. The jacks 54 are matched with the connecting plug 71; a fastening convex block is further provided on the upper side of the connecting plug 71, and tool buckles 53 matched with the fastening convex block are provided at both ends of the support crossbeam 5, so that the support crossbeam 5 is fastened and connected to the side shift mechanism 7. The crossbeam main rod 51 is fixedly connected to the mounting hole 441 of the rotary cam 44; the crossbeam transition connecting plates 52 are respectively connected to the two rear door inner panel supports 6 and are locked and fixed using the tool buckles 53.

[0062] Further, two positioning holes 35 and four pressing plate grooves 34 are further provided on the fixing plate 31. The positioning holes 35 are used for installation and positioning during production; the pressing plate grooves 34 are used for clamping and fixing during production; holes 33 are provided on the support mounting connecting plate 32, and the rotary cylinder 43 is arranged in the holes 33.

[0063] Specific implementation manner: When the sensor 63 detects the stamping part, the side-shifting air cylinder 76 pushes the side-shifting slider 74 to move leftward along the side-shifting slideway 73, driving the main support rod 61 to move, and further realizing the leftward movement of the inner panel 1 of the left rear door. By the same principle, the inner panel 2 of the right rear door moves rightward, and finally the two parts move in two directions along the Y-axis respectively. Further, the rotating air cylinder 43 drives the rotating cam 44 to rotate along the rotating base 41, driving the support beam 5 to rotate, and further driving the two rear door inner panel supports 6 to rotate, and finally realizing the rotational movement of the two parts around the Y-axis.
