Description

Technical Field

[0001] The utility model relates to the technical field of automated processing equipment, in particular to a mechanical arm lifting and adjusting mechanism for processing an instrument panel skeleton assembly. Background Art

[0002] In the process of automobile manufacturing, the skeleton assembly of the automobile instrument panel plays a role in supporting and positioning various parts. Its quality indirectly affects the matching effect of the outside. Therefore, the role of the skeleton assembly of the instrument panel in the whole vehicle cannot be ignored. At present, with the gradual popularization of automated processing equipment, the skeleton assembly of the instrument panel will use a highly automated robotic arm to perform processing operations during the processing.

[0003] However, in the prior art, some mechanical arms are not convenient for quickly adjusting the lifting height during use, and thus cannot adapt to the processing requirements of different heights, reducing the processing efficiency. Therefore, we propose a lifting and adjusting mechanism for a mechanical arm for processing an instrument panel frame assembly. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a lifting and adjusting mechanism for a mechanical arm for processing an instrument panel frame assembly, which can quickly adjust the lifting height of the mechanical arm to meet processing requirements at different heights, thereby improving processing efficiency.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A lifting and adjusting mechanism for a mechanical arm of an instrument panel skeleton assembly processing comprises a support frame, on which a lifting and adjusting assembly and a heat dissipation mounting assembly are sequentially arranged, and the lifting and adjusting assembly comprises two lead screws mounted in the support frame for vertical rotation, a same lifting block threadedly connected to the two lead screws, two worm gears sequentially fixedly sleeved on the top ends of the two lead screws, a dual-axis stepper motor fixed to the outer wall of the top of the support frame by bolts, and two worms sequentially fixedly sleeved on the two output shafts of the dual-axis stepper motor.

[0007] As a preferred technical solution, the two worms are respectively meshed with two worm wheels. The self-locking performance after the worm and the worm wheel are meshed can prevent the output shaft of the dual-axis stepper motor from being damaged by a large reverse torque, which is beneficial to reducing the failure rate of the dual-axis stepper motor and ensuring the stability of the lifting action of the robotic arm. Counterweights are welded on the lower outer walls on both sides of the support frame. The setting of the counterweights can ensure the stability of the support frame.

[0008] As a preferred technical solution, the lifting block is embedded with a linear bearing, a guide shaft is vertically welded inside the support frame, and the linear bearing is movably connected to the guide shaft, which can ensure the stability and smoothness of the robot arm during lifting and adjusting.

[0009] As a preferred technical solution, a mounting plate is welded to an upper outer wall of one side of the support frame, and a PLC controller is fixedly mounted on the front outer wall of the mounting plate.

[0010] As a preferred technical solution, the heat dissipation mounting assembly includes a connecting plate welded to the side wall of the lifting block, a cooling fan fixedly mounted on the bottom of the connecting plate, and a robotic arm mounting base fixedly connected to the top outer wall of the connecting plate, and the top of the robotic arm mounting base is provided with evenly distributed heat dissipation holes, which facilitates the heat dissipation and cooling of the installed robotic arm to ensure the normal operation of the robotic arm.

[0011] As a preferred technical solution, a distance measuring sensor is fixedly installed on the outer wall of one side of the lifting block, and the distance measuring sensor and the dual-axis stepper motor are electrically connected to the PLC controller. In this way, the lifting height of the lifting block can be detected in real time by the distance measuring sensor, thereby achieving the effect of accurately adjusting the lifting height of the robotic arm.

[0012] The beneficial effects of the utility model are:

[0013] 1. The utility model can quickly and accurately adjust the lifting height of the robot arm through the coordinated cooperation of the PLC controller, the distance sensor and the lifting and adjusting component to adapt to the processing requirements of different heights and improve the processing efficiency;

[0014] 2. The utility model facilitates heat dissipation and temperature reduction of the installed mechanical arm by setting a heat dissipation installation component, thereby ensuring the normal operation of the mechanical arm;

[0015] 3. The utility model can prevent the output shaft of the dual-axis stepper motor from being damaged by a large reverse torque through the self-locking performance after the worm and the worm wheel are engaged, which is beneficial to reducing the failure rate of the dual-axis stepper motor and ensuring the stability of the lifting action of the robot arm.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Example

[0023] Reference Figure 1-4 , a mechanical arm lifting and adjusting mechanism for processing an instrument panel frame assembly, comprising a support frame 1;

[0024] Furthermore, the lower outer walls of both sides of the support frame 1 are welded with counterweight blocks 16. The arrangement of the counterweight blocks 16 can ensure the stability of the support frame 1. The support frame 1 is provided with a lifting adjustment component and a heat dissipation installation component in sequence;

[0025] Specifically, the lifting and adjusting assembly includes two lead screws 2 and a lifting block 3: the two lead screws 2 are both installed in the support frame 1 along the vertical rotation and the thread directions of the two are the same, and the two lead screws 2 are both threadedly connected to the lifting block 3;

[0026] It also includes two worm wheels 4 and two worms 6: the two worm wheels 4 are fixedly sleeved on the top ends of the two lead screws 2 in sequence, and the two worms 6 are respectively meshed with the two worm wheels 4;

[0027] It also includes a dual-axis stepper motor 5: the dual-axis stepper motor 5 is fixed to the top outer wall of the support frame 1 by bolts, and two worms 6 are fixedly sleeved on the two output shafts of the dual-axis stepper motor 5 in sequence;

[0028] In addition, a linear bearing 7 is embedded in the lifting block 3, and a guide shaft 8 is vertically welded inside the support frame 1. The linear bearing 7 is movably connected to the guide shaft 8, which can ensure the stability and smoothness of the robot arm during the lifting and lowering adjustment process. A mounting plate 9 is welded to the upper outer wall of one side of the support frame 1, and a PLC controller 10 is fixedly installed on the front outer wall of the mounting plate 9. A distance sensor 15 is fixedly installed on the outer wall of one side of the lifting block 3. The distance sensor 15 and the dual-axis stepper motor 5 are electrically connected to the PLC controller 10. In this way, the lifting height of the lifting block 3 is detected in real time by the distance sensor 15, thereby achieving the effect of accurately adjusting the lifting height of the robot arm.

[0029] Specifically, the heat dissipation installation component includes a connecting plate 11 welded to the side wall of the lifting block 3, a cooling fan 12 fixedly installed at the bottom of the connecting plate 11, and a robotic arm mounting base 13 fixedly connected to the top outer wall of the connecting plate 11. The top of the robotic arm mounting base 13 is provided with evenly distributed heat dissipation holes 14, which facilitates the heat dissipation and cooling of the installed robotic arm to ensure the normal operation of the robotic arm.

[0030] The working principle of this embodiment is as follows: first, the mechanical arm used for processing the instrument panel skeleton assembly is fixedly mounted on the mechanical arm mounting seat 13. At this time, the cooling fan 12 and the evenly distributed cooling holes 14 facilitate heat dissipation and cooling of the installed mechanical arm to ensure the normal operation of the mechanical arm;

[0031] Secondly, after the required lifting height is input on the PLC controller 10, the output shaft of the dual-axis stepper motor 5 will control the two worms 6 to rotate forward or reverse, and then the two worm wheels 4 meshing therewith will control the two lead screws 2 with the same thread direction to rotate forward or reverse synchronously, and then with the cooperation of the guide shaft 8 and the linear bearing 7, the lifting block 3 will drive the robotic arm installed on the robotic arm mounting seat 13 to perform lifting and lowering movements. At this time, the distance measuring sensor 15 will accurately measure the lifting height. When the required lifting height is reached, the distance measuring sensor 15 will transmit the signal to the PLC controller 10, and the PLC controller 10 will control the dual-axis stepper motor 5 to stop running immediately. In this way, the lifting height of the robotic arm can be adjusted quickly and accurately to meet the processing requirements of different heights, thereby improving the processing efficiency.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
