[0035] Please refer to Figures 1 to 7 , and a jig for the robot leg housing provided in the embodiment of the present application will be described hereinafter. The jig for the robot leg housing is used for clamping the leg housing 100 of the robot. The leg housing 100 of the robot is mainly the leg housing 100 of a profiling robot, such as the leg housing 100 of a humanoid robot, etc.
[0036] Please refer to Figure 1 and Figure 4, a jig for a robot leg housing, comprising: a workbench 10, a first pressing and fixing device 20, and a second pressing and fixing device 30; the workbench 10 has a processing area 11; the first pressing and fixing device 20 is arranged on the workbench 10 and is located on the outer peripheral side of the processing area 11; the first pressing and fixing device 20 includes a rotating and pressing-down mechanism 21 and a first pressing block 22, the first pressing block 22 is connected to the rotating and pressing-down mechanism 21, and the rotating and pressing-down mechanism 21 is used to drive the first pressing block 22 to rotate and move up and down; the second pressing and fixing device 30 is arranged on the workbench 10 and is located within the processing area 11; the second pressing and fixing device 30 includes a lifting driving mechanism 31, a connecting rod 32, and a second pressing block 33, the connecting rod 32 is detachably connected to the lifting driving mechanism 31, the lifting driving mechanism 31 is used to drive the connecting rod 32 to move up and down, and the second pressing block 33 is connected to the connecting rod 32.
[0037] Please refer to Figure 2 , when using the jig for the robot leg housing of the embodiment of the present application to clamp the leg housing 100 of the robot, first detach the connecting rod 32 from the lifting driving mechanism 31 to separate the connecting rod 32 and the second pressing block 33 from the lifting driving mechanism 31, then place the leg housing 100 in the processing area 11, and drive the first pressing block 22 to rotate and press down through the rotating and pressing-down mechanism 21 of the first pressing and fixing device 20, so as to rotate the first pressing block 22 above the processing area 11 and press it against the leg housing 100. A through hole 102 is provided in the die-casting blank 101 of the leg housing 100. Pass the connecting rod 32 through the through hole 102 in the die-casting blank 101 and detachably connect it to the lifting driving mechanism 31. The lifting driving mechanism 31 drives the connecting rod 32 to descend, so that the second pressing block 33 presses against one end of the leg housing 100, thereby realizing stably clamping the leg housing 100 on the workbench 10.
[0038] After the processing of the leg housing 100 is completed and the leg housing 100 needs to be removed from the workbench 10, the rotating and pressing-down mechanism 21 of the first pressing and fixing device 20 drives the first pressing block 22 to rise and rotate, so as to rotate the first pressing block 22 to the outer peripheral side of the processing area 11, detach the connecting rod 32 and the second pressing block 33 from the lifting driving mechanism 31 to make the second pressing block 33 no longer press against the leg housing 100. At this time, the leg housing 100 can be removed from the processing area 11.
[0039] The fixture for the robot leg housing provided by this application, compared with the prior art, when clamping the leg housing 100, the rotation and pressing mechanism 21 of the first pressing and fixing device 20 drives the first pressing block 22 to rotate and move up and down, so that the first pressing block 22 automatically presses on and automatically moves away from the leg housing 100. After passing the connecting rod 32 through the through hole 102 in the leg housing 100 and detachably connecting it to the lifting drive mechanism 31, the lifting drive mechanism 31 drives the connecting rod 32 to descend and ascend, so that the second pressing block 33 automatically presses on and automatically moves away from the leg housing 100 under the drive of the connecting rod 32, which saves time and effort, is beneficial to improving the processing efficiency and reducing the manual labor amount. At the same time, it effectively ensures the consistency of the pressing force of the first pressing block 22 and the second pressing block 33 on the leg housing 100, is not easy to damage the leg housing 100, and can be well pressed on the leg housing 100. In addition, the first pressing and fixing device 20 located on the outer peripheral side of the processing area 11 and the second pressing and fixing device 30 located in the processing area 11 cooperate to press and fix the leg housing 100 placed in the processing area 11, which is beneficial to improving the clamping stability of the leg housing 100.
[0040] In an embodiment of this application, the rotation and pressing mechanism 21 is a rotation and pressing cylinder, the rotation and pressing cylinder is arranged on the workbench 10, and the first pressing block 22 is connected to the top of the rotation and pressing cylinder. Of course, in other embodiments of this application, the rotation and pressing mechanism 21 may also include a rotation cylinder and a lifting cylinder. For example, the rotation cylinder is arranged on the workbench 10, the lifting cylinder is arranged on the rotation cylinder, the first pressing block 22 is connected to the lifting cylinder. When the rotation cylinder rotates, it drives the lifting cylinder and the first pressing block 22 to rotate simultaneously. When the lifting cylinder moves up and down, it drives the first pressing block 22 to rise and press down.
[0041] In an embodiment of this application, please refer to Figure 1 and Figure 2 Figure, the number of the first pressing and fixing devices 20 is multiple, and the multiple first pressing and fixing devices 20 are distributed at intervals around the processing area 11. By arranging multiple first pressing and fixing devices 20, when clamping the leg housing 100 in the processing area 11, the first pressing blocks 22 of the multiple first pressing and fixing devices 20 are used to simultaneously press different parts of the leg housing 100, which is beneficial to improving the clamping stability of the leg housing 100.
[0042] In an embodiment of this application, please refer to Figure 1 and Figure 2, the second pressing and fixing device 30 is located inside one end of the processing area 11. The number of the first pressing and fixing devices 20 is two. One of the first pressing and fixing devices 20 is located outside the end of the processing area 11 away from the second pressing and fixing device 30, and the other first pressing and fixing device 20 is located between the second pressing and fixing device 30 and one of the first pressing and fixing devices 20.
[0043] Optionally, the length direction of the processing area 11 is consistent with the length direction of the leg housing 100. The second pressing and fixing device 30 and one of the first pressing and fixing devices 20 are respectively located at opposite ends of the processing area 11 along the length direction of the processing area 11.
[0044] When clamping the leg housing 100, the two ends of the leg housing 100 are respectively pressed and fixed by the cooperation of the second pressing and fixing device 30 and one of the first pressing and fixing devices 20, and the other first pressing and fixing device 20 presses on the middle part of the leg housing 100 or a position close to the middle part of the leg housing 100, so that the leg housing 100 is subjected to more balanced force and is not easily damaged, and at the same time, it is beneficial to improve the clamping stability of the leg housing 100.
[0045] Of course, in other embodiments, the number of the first pressing and fixing devices 20 can also be other numbers, for example, three, four, five or more, etc. At the same time, the circumferential layout mode of the multiple first pressing and fixing devices 20 can also be designed according to requirements.
[0046] In an embodiment of the present application, please refer to Figure 1 and Figure 5 , one end of the first pressing block 22 is connected to the rotary pressing-down mechanism 21. The first pressing and fixing device 20 further includes a pressing-down column 23. The pressing-down column 23 is connected to the other end of the first pressing block 22 and extends towards the workbench 10.
[0047] When the rotary pressing-down mechanism 21 drives the first pressing block 22 to rotate to a preset position and drives the first pressing block 22 to descend to a preset height, the pressing-down column 23 presses on the leg housing 100. It can be understood that the first pressing block 22 presses on the leg housing 100 through the pressing-down column 23. In this way, it is beneficial to shorten the stroke of the lifting movement of the rotary pressing-down mechanism 21, and the pressing-down column 23 can accurately press on the part of the leg housing 100 that can bear force, avoiding damaging the vulnerable and easily deformed part of the leg housing 100.
[0048] Optionally, the lifting drive mechanism 31 is a lifting cylinder or a motor, etc.
[0049] In an embodiment of the present application, please refer to Figure 6 and Figure 7 , one end of the connecting rod 32 is inserted into the lifting drive mechanism 31.
[0050] Optionally, a socket is provided on the telescopic rod of the lifting drive mechanism 31, and one end of the connecting rod 32 is inserted into the socket. The connecting rod 32 may be a screw or a threaded rod, and the socket may be a threaded hole. The connecting rod 32 is inserted into the socket and connected with the socket threadedly to realize the detachable connection between the connecting rod 32 and the lifting drive mechanism 31, so that the connecting rod 32 can be removed from the lifting drive mechanism 31 or connected to the lifting drive mechanism 31 by screwing the connecting rod 32. The connecting rod 32 is inserted into the socket on the lifting drive mechanism 31 and connected with the socket threadedly to realize the detachable connection between the connecting rod 32 and the lifting drive mechanism 31, so that the connecting rod 32 can be removed from the lifting drive mechanism 31 or connected to the lifting drive mechanism 31 by screwing the connecting rod 32. Of course, the connecting rod 32 can also be inserted into the socket on the lifting drive mechanism 31 and have an interference fit with the socket to achieve a detachable connection between the connecting rod 32 and the lifting drive mechanism 31. Alternatively, the connecting rod 32 can be snapped or magnetically connected to the socket to achieve a detachable connection between the connecting rod 32 and the lifting drive mechanism 31 shell.
[0051] In one embodiment of the present application, see Figure 6 The connecting rod 32 includes a rod body 321 and a cap head 322. One end of the rod body 321 is detachably connected to the lifting drive mechanism 31, and the cap head 322 is connected to the other end of the rod body 321. The second pressing block 33 is provided with a clearance hole 331 and a positioning hole 332 for the rod body 321 to pass through. The clearance hole 331 is connected to the positioning hole 332, and the width of the clearance hole 331 is greater than the width of the cap head 322, and the width of the positioning hole 332 is less than the width of the cap head 322.
[0052] When it is necessary to use the second clamping and fixing device 30 to clamp and fix the leg shell 100, the rod body 321 of the connecting rod 32 is passed through the through hole 102 on the leg shell 100 and is detachably connected to the lifting drive mechanism 31. Since the width of the clearance hole 331 is greater than the width of the cap head 322, the cap head 322 can be allowed to pass through the clearance hole 331 on the second pressing block 33, so that the second pressing block 33 is sleeved on the connecting rod 32, and the second pressing block 33 is moved in the horizontal direction so that the connecting rod 32 is in a position to pass through the positioning hole 332. At this time, since the width of the positioning hole 332 is less than the width of the cap head 322, the second pressing block 33 cannot be detached from the cap head 322, and the lifting drive mechanism 31 drives the second pressing block 33 to descend to clamp the second pressing block 33 to the leg shell 100.
[0053] Similarly, when the second clamping and fixing device 30 is no longer needed to position the leg shell 100, the lifting drive mechanism 31 drives the second clamping block 33 to rise, and moves the second clamping block 33 in the opposite direction in the horizontal direction, so that the connecting rod 32 is in a position to pass through the clearance hole 331, and the second clamping block 33 is removed from the connecting rod 32, and the connecting rod 32 is removed from the lifting drive mechanism 31.
[0054] Optionally, the cross-sections of the connecting rod 32 and the cap head 322 are both circular, and the diameter of the cap head 322 is larger than the diameter of the connecting rod 32, the clearance hole 331 is a circular hole, and the inner diameter of the clearance hole 331 is larger than the diameter of the cap head 322, so that the cap head 322 can pass through the clearance hole 331, and the positioning hole 332 is a bar hole, and the width of the positioning hole 332 is larger than the diameter of the connecting rod 32 and smaller than the diameter of the cap head 322. Of course, the cross-sections of the connecting rod 32 and the cap head 322 can also be other shapes, such as rectangular, elliptical, etc. Similarly, the clearance hole 331 can also be a rectangular hole or an elliptical hole, and the positioning hole 332 can also be a circular hole, a rectangular hole, or an elliptical hole, as long as it is ensured that the cap head 322 can smoothly pass through the clearance hole 331 but cannot pass through the positioning hole 332.
[0055] In one embodiment of the present application, see Figure 1 , Figure 3 and Figure 4 The robot leg housing fixture also includes a first positioning block 40, which is disposed on the workbench 10 and located in the middle of the processing area 11. The length direction of the first positioning block 40 is consistent with the length direction of the processing area 11. The shape of the first positioning block 40 is adapted to the middle space 103 of the leg housing 100 facing the side of the workbench 10. When the leg housing 100 is placed in the processing area 11, the first positioning block 40 adaptively protrudes into the middle space 103 of the leg housing 100 and is supported by the leg housing 100, effectively preventing the leg housing 100 from being offset.
[0056] In one embodiment of the present application, see Figure 1 , Figure 3 and Figure 4 The robot leg shell fixture also includes a second positioning block 50, which is arranged on the workbench 10 and is located at the same end of the processing area 11 as the second clamping and fixing device 30, and the second positioning block 50 is located above the lifting drive mechanism 31. The second positioning block 50 is provided with a through hole 51 for the connecting rod 32 to pass through.
[0057] Optionally, the second positioning block 50 is generally U-shaped. When the leg housing 100 is placed in the processing area 11, the second positioning block 50 protrudes into the end space of the leg housing 100 near the second pressing and fixing device 30 and facing the end of the workbench 10, and both ends of the second positioning block 50 are supported on the bottom of the leg housing 100, effectively preventing the leg housing 100 from shifting.
[0058] In an embodiment of the present application, please refer to Figure 1 , Figure 3 and Figure 4 , the second pressing and fixing device 30 is located inside one end of the processing area 11. The robot leg housing tooling fixture further includes a third positioning block 60. The third positioning block 60 is arranged on the workbench 10, and the third positioning block 60 is located inside the end of the processing area 11 far from the second pressing and fixing device 30.
[0059] When the leg housing 100 is placed in the processing area 11, the end of the leg housing 100 far from the second pressing and fixing device 30 is in a suspended state relative to the workbench 10. By supporting the end of the leg housing 100 far from the second pressing and fixing device 30 with the third positioning block 60, it is beneficial to improve the stability of the leg housing 100 placed in the processing area 11. At the same time, it effectively prevents the end of the leg housing 100 far from the second pressing and fixing device 30 from shaking or deforming downward when the end of the leg housing 100 far from the second pressing and fixing device 30 is under one of the first pressing and fixing devices 20.
[0060] It can be understood that by pressing and fixing the leg housing 100 with the first pressing and fixing device 20 and the second pressing and fixing device 30, and supporting and limiting the leg housing 100 placed in the processing area 11 with the first positioning block 40, the second positioning block 50 and the third positioning block 60, the leg housing 100 can be stably clamped in the processing area 11, effectively preventing the leg housing 100 from shifting, thereby being beneficial to improving the processing accuracy.
[0061] In an embodiment of the present application, please refer to Figure 1 , the robot leg housing tooling fixture further includes two support seats 70. The two support seats 70 are connected to the opposite ends of the workbench 10.
[0062] By supporting the opposite ends of the workbench 10 with the two support seats 70, the workbench 10 is in a suspended state, so that part of the rotation and pressing mechanism 21 and the lifting drive mechanism 31 can pass through the workbench 10 and extend below the workbench 10, effectively reducing the occupation of the space above the workbench 10 by the first pressing and fixing device 20 and the second pressing and fixing device 30, and facilitating the clamping and disassembly of the leg housing 100.
[0063] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
