Description

Technical Field

[0001] The utility model relates to the technical field of robot grippers, in particular to a supporting frame structure of a gripper of an automobile welding robot. Background Art

[0002] The intelligent welding manufacturing process of automotive welding robots involves the intelligent handling and grasping of automotive parts. The intelligent robots need to control and use grippers to complete the grasping and handling of automotive parts. When grasping parts, the intelligent robot gripper often loosens after being stressed due to the lack of connecting reinforcement plates between the gripper support frame. This can easily lead to bolt breakage. Furthermore, the flange pins often slip out, which can easily cause the flange screw to be stressed and break. Once a problem occurs with the support frame of the automotive welding robot gripper, the machine needs to be shut down for replacement. This not only directly affects the welding schedule and requires readjustment of the intelligent robot's operating program, but also directly affects the welding quality, which is time-consuming and labor-intensive. Therefore, the reliability and strength of the automotive welding robot gripper support structure are particularly important.

[0024] In this embodiment, if Figure 1 、 Figure 2 and Figure 3 As shown, the locking assembly includes a rubber pad 9 embedded in one side of the grip base plate 2, a through hole 11 is provided at one end of the inner side of the rubber pad 9, a locking plate 12 is installed on one side of the grip base plate 2 at the through hole 11, and a splicing groove 4 is provided on one side of the grip connection seat 3 at the through hole 11, and the locking plate 12 and the splicing groove 4 are slidably connected. First, the grip connection seat 3 is made to fit the surface of the rubber pad 9 on the grip base plate 2, so that the locking plate 12 slides into the inner side of the splicing groove 4 through the through hole 11, and continues to squeeze the rubber pad 9 between the two, so that the locking plate 12 enters the inner side of the lower pressure groove 6 and contacts the rotating plate 14.

[0025] In this embodiment, if Figure 1 、 Figure 2 and Figure 3As shown, a lower pressure groove 6 is provided on one side of the splicing groove 4 inside the gripper connecting seat 3, and a connecting rod 13 is rotatably connected to the inner wall of the lower pressure groove 6. A rotating plate 14 is sleeved on the outer side of the connecting rod 13, and the lower pressure groove 6 is communicated with the inner side of the splicing groove 4. The opposite ends of the locking plate 12 and the rotating plate 14 are provided with guide slopes 15 that fit each other. A mounting groove is provided on one side of the rotating plate 14 below its guide slope 15, and a connecting spring 7 is installed between the mounting groove and the inner wall of the lower pressure groove 6. A rotating groove is provided on the inner side of the rotating plate 14 at its guide slope 15, and a movable rod is rotatably connected to the inner side of the rotating groove. A convex plate 16 is sleeved on the outer side of the movable rod, and a torsion spring 17 is installed between the movable rod and the inner wall of the rotating groove. A groove 18 is provided on the inner side of the locking plate 12 at its guide slope 15, and the convex plate 16 is installed One side is provided with an abutment slope 19 that fits with the guide slope 15. Then, the locking plate 12 and the guide slope 15 on the rotating plate 14 fit and squeeze each other, forcing the connecting spring 7 to be stretched, allowing the rotating plate 14 and the connecting rod 13 to rotate a certain angle around the axis. As the locking plate 12 continues to move, the locking plate 12 contacts the convex plate 16, and the guide slope 15 squeezes the abutment slope 19 to force the torsion spring 17 to drive the convex plate 16 to retract into the inner side of the rotating groove. After the groove 18 is close to the rotating groove, the torsion spring 17 rebounds and drives the convex plate 16 into the inner side of the groove 18. At this time, the gripper connecting seat 3 is released, the rubber pad 9 rebounds a distance, the locking plate 12 is dragged back, and the convex plate 16 is abutted against the inner wall of the groove 18, completing the position locking of the gripper connecting seat 3 and the robot gripper installed thereon.

[0026] In this embodiment, if Figure 1 、 Figure 2 and Figure 3 As shown, the torsion assembly includes an operating groove opened at one end of the interior, and the connecting rod 13 extends to the end inside the operating groove and is equipped with a torsion plate 20. The outer side of the torsion plate 20 is printed with anti-slip grooves, and a limit plate 21 is installed at one end of the rotating plate 14. The inner wall of the lower pressure groove 6 is provided with a limit groove that is slidably connected to the limit plate 21.

At this time, loosening the torsion plate 20 will not re-engage, and the gripper connecting seat 3 can be removed to maintain and replace the robot gripper.

[0027] In this embodiment, if Figure 1 、 Figure 2 and Figure 3As shown, a closing groove is provided on one side of the outer wall of the gripper connecting seat 3, and a closing plate 10 is slidably connected to the inner side of the closing groove.

Synchronous blocks slidably connected to the synchronous groove 22 are installed at both ends of the closing plate 10. A buckle groove 5 is provided on one side of the closing plate 10, and a magnetic block is embedded in one end of the closing plate 10. An iron block 8 adsorbed by the magnetic block is embedded in the inner wall of the closing groove. Furthermore, after locking the position of the robot gripper and the gripper connecting seat 3, the buckle groove 5 can be buckled to cooperate with the synchronous block and the synchronous groove 22 to drive the closing plate 10 to slide on the inside of the closing groove, so that the magnetic block and the iron block 8 are fitted and adsorbed, and the twisting plate 20 is covered on the inside of the operating groove to prevent the connection part from loosening due to accidental touch by personnel after assembly.

[0028] The implementation principle of the support frame structure of the automobile welding robot gripper in the embodiment of the present application is as follows: the gripper connecting seat 3 is fitted with the surface of the rubber pad 9 on the gripper base plate 2, so that the locking plate 12 slides into the inner side of the splicing groove 4 through the through hole 11, and continues to squeeze the rubber pad 9 between the two, so that the locking plate 12 enters the inner side of the lower pressing groove 6 and contacts the rotating plate 14, and the locking plate 12 and the guide slope 15 on the rotating plate 14 fit and squeeze each other, forcing the connecting spring 7 to be stretched, so that the rotating plate 14 and the connecting rod 13 rotate a certain angle around the axis. As the locking plate 12 continues to move, the locking plate 12 contacts the convex plate 16, and the guide slope 15 squeezes the abutment slope 19, forcing the torsion spring 17 to drive the convex plate 16 to retract into the inner side of the rotating groove. After the groove 18 approaches the rotating groove, the torsion spring 17 rebounds and drives the convex plate 16 into the inner side of the groove 18. At this time, the gripper connecting seat 3 is released, the rubber pad 9 rebounds a certain distance, and the locking plate 12 is pulled back When the gripper arm 3 is locked, the locking plate 12 is locked, and the locking plate 12 is unlocked and the locking plate 12 is unlocked.
