However, multi-axis robotic arm operation is delayed and inefficient. If multiple drilling processes are required, multiple robotic arms are needed to meet the demands. Multi-axis robotic arms are expensive, which increases the cost for enterprises.

[0024] See attached document Figure 1-5 A multi-station metal part drilling robot includes a worktable 1, a rotary operating table 2 on the worktable 1, the rotary operating table 2 being an intermittent rotary table driven by a cam divider, drilling mechanisms 3 on both sides of the rotary operating table 2, multiple clamping mechanisms 4 and limiting plates 7 on the rotary worktable 2, the limiting plates 7 being arranged one-to-one with the clamping mechanisms 4, the lower end of the clamping mechanism 4 being provided with a lifting mechanism 5 connected thereto, the lifting mechanism 5 being arranged one-to-one with the clamping mechanism 4, the drilling mechanism 3 including an X-axis moving module 31, a Z-axis moving module 32 and a drilling machine 33, the clamping mechanism 4 including a clamping assembly 41 and a flipping seat 42.

[0025] See attached document Figure 1-5 Two punching mechanisms 3 are respectively set on both sides of the worktable 1. The punching mechanism 3 is correspondingly set with the clamping mechanism 4. The punching mechanism 3 realizes the position adjustment in the X-axis and Z-axis directions through the X-axis moving module 31 and the Z-axis moving module 32. The two punching mechanisms 3 correspond to two punching stations, and the two punching stations correspond to two different punching parts.

[0026] See attached document Figure 1-5 The clamping assembly 41 includes a self-centering clamping seat 411 and a pushing cylinder 412. A rotary cylinder 413 is located at the lower end of the self-centering clamping seat 411. A support block 414 is located at the piston end of the rotary cylinder 413. The rotary cylinder 413 is fixedly positioned within the self-centering clamping seat 411, clamping the bottom of the metal part. The rotary cylinder 413 rotates and lifts the support block 414 upwards, causing the support block 414 to press against the bottom of the metal part from below. The self-centering clamping seat 411 includes two clamping fingers 4111. A second clamping finger 4112 is provided in the middle, and a linkage plate 4113 is provided on one side of the first clamping finger 4111 for rotational connection. A push block 4114 is connected to the lower end of the second clamping finger 4112. The linkage plate 4113 is rotatably connected to the first clamping finger 4111 and the push block 4114 respectively. The lower end of the push block 4114 is connected to the piston end of the push cylinder 412. After the self-centering clamping seat 411 is pushed out by the push cylinder 412, the first clamping finger 4111 and the second clamping finger 4112 are brought together to the middle for clamping metal parts.

[0027] See attached document Figure 1-5 The flipping seat 42 is fixedly connected to the clamping assembly 41. The flipping seat 42 is provided with a rotating shaft 43 and a positioning pin 44. After flipping, the positioning pin 44 is inserted into the corresponding limiting plate 7 to ensure that the flipping seat 42 maintains horizontal stability after flipping inward to the rotating operating table 2. The rotating operating table 2 is provided with multiple mounting slots 21 corresponding to the flipping seat 42. The mounting slots 21 are provided with positioning steps 22. After the flipping seat 42 is flipped, the side with the positioning pin 44 is flipped 90 degrees inward to the rotating operating table 2. The end of the flipping seat 42 is restricted to the flipping angle by the positioning step 22 to achieve positioning. The rotating shaft 43 is rotatably connected to the mounting slot 21 and is fixedly connected to the flipping seat 42. The flipping seat 42 is also provided with a rotating connector 421. The flipping seat 42 achieves the rotation angle through the rotating shaft 43. The rotating connector 421 is used to connect the lifting mechanism 5 to achieve mutual linkage.

[0028] See attached document Figure 1-5The lifting mechanism 5 includes a lifting cylinder 51. A linkage arm 52 is connected to the piston end of the lifting cylinder 51. Both ends of the linkage arm 52 are rotatably connected to the rotating connector 421 and the piston end of the lifting cylinder 51, respectively. The piston end of the lifting cylinder 51 and the rotating connector 421 are located on different axes. The rotating connector 421 is brought to the same axis by the tension and rotation of the linkage arm 52. The lifting cylinder 51 is fixed to the lower end of the rotating operating table 2 by an L-shaped positioning plate 6. The lifting cylinder 51 is suspended below the rotating operating table 2 by the L-shaped positioning plate 6. The lifting mechanism 51 is used in conjunction with the rotating... The spacing between the operating tables 2 provides space for the linkage arm 52 to swing and move up and down. After the piston end of the lifting cylinder 51 retracts downward and resets, it drives the linkage arm 52 connected to it to move downward. The linkage arm 52 pulls down and rotates the rotating connector 421 connected to the rotating shaft 43 clockwise. The rotating connector 421 drives the rotating shaft 43, the flipping seat 42, and the clamping assembly 41 to flip as a whole. During the pulling process, the linkage arm 52 gradually maintains a perpendicular state with the rotating operating table 2. When it reaches a perpendicular state, the flipping angle of the flipping seat 42 reaches 90 degrees and it is flipped into place.

[0029] See attached document Figure 1-5 The limiting plate 7 includes a base 71 fixedly connected to the rotary operating table 1. A dovetail groove 711 is provided on the base 71. A locking block 72 and a spring 73 are provided inside the base 71. Both ends of the spring 73 are fixedly connected to the locking block 72 and the base 71, respectively. The spring 73 is in a contracted state in its initial state. A limiting groove 721 is also provided on the locking block 72. The opening of the limiting groove 721 is located at the upper end of the locking block 72. The locking block 72 is slidably connected to the base 71 through the dovetail groove 711. The locking block 72 moves back and forth along the dovetail groove 711. When the block 72 is moved, one end of the locking block 72 is fixedly connected to the spring 73 and automatically resets through the spring 73. After the positioning pin 44 on the flipping seat 42 is flipped, it presses down on the locking block 72 and locks into the limiting slot 721 on the locking block 72. The limiting slot 721 has a connected inlet and a slot. The opening end of the inlet is facing upward. After the positioning pin 44 presses down on the inlet, the locking block 72 moves to one side. After the positioning pin 44 enters the inlet, the locking block 72 automatically resets, and the positioning pin 44 enters the slot for positioning.

[0030] In this embodiment, the multi-station metal part drilling robot provided by this technical solution is used after being connected online with the metal part loading conveyor line and the unloading collection box. One end of the metal part loading conveyor line is connected to one of the clamping mechanisms 4 on the rotary operating table 2. The position of the clamping mechanism 4 should avoid the two drilling mechanisms 3. The metal part loading conveyor line can be set up to load materials separately or simultaneously on two lines according to production needs. The unloading collection box can be installed below the second drilling station. The specific implementation method is as follows: First, after the rotary operating table 2 is started, it rotates intermittently. Multiple clamping mechanisms 4 and lifting mechanisms 5 rotate with the rotary operating table 2. Metal parts are fed one by one in an orderly manner through the feeding conveyor line. The self-centering clamping seat 411 is driven by the pushing cylinder 412 to clamp the metal parts. Subsequently, the clamping mechanism 4, after being gripped, rotates with the rotating operating table 2 to the drilling mechanism 3 on one side. After being placed below the drilling station, it moves downward through the Z-axis moving module 32, driving the drilling machine 33 to drill holes in the end face of the metal part. Then, it moves with the rotating operating table 2 to the next drilling station. During the rotation, the clamping mechanism 4 flips the flipping seat 42 by 90 degrees through the lifting mechanism 5, so that the self-centering clamping seat 41 is in a horizontal state after flipping. After entering the second drilling station, the drilling machine 33 is adjusted to the drilling position through the X-axis moving module 31, and the Z-axis moving module 32 is started to move downward, driving the drilling machine 33 to drill holes in the side wall of the metal part, thereby realizing the drilling operation of multiple parts of the metal part. Finally, the metal part, after being punched twice, is reset by releasing the flip seat 42, and then discharged by the clamping mechanism 4 and the lifting mechanism 5, falling into the preset discharge collection box.

[0031] In summary, by setting up a rotating operating table 2 that can rotate intermittently and multiple clamping mechanisms 4, continuous feeding and drilling operations at multiple workstations can be achieved; by setting up a combination of self-centering clamping seat 41, flipping seat 42, lifting mechanism 5 and limiting clamping table 7, and cooperating with two drilling mechanisms 3, drilling operations at multiple parts of metal parts can be achieved.

[0032] The above-described embodiments are merely illustrative of certain implementations of the present invention, and are described in a relatively specific and detailed manner. However, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
