[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0034] In specific implementation, such as Figures 1-6 As shown, this utility model provides a technical solution: a mechanical arm crossbar adhesive assembly fixture, including a first combined base 1 and a second combined base 2, which are connected by a hinge;
[0035] The folding adjustment component 3, the first assembly component 4, and the second assembly component 5 are provided. The folding adjustment component 3 is rotatably disposed inside the first combined base 1 and the second combined base 2, and the first assembly component 4 and the second assembly component 5 are movably mounted on the outside of the folding adjustment component 3.
[0036] The folding adjustment assembly 3 includes a stud 31 and a reverse threaded post 35. The stud 31 is rotatably installed in a rotating hole provided on the inner side of the first combined base 1, and the reverse threaded post 35 is rotatably installed in a rotating hole provided on the inner side of the second combined base 2. A retaining plate 34 is fixedly installed at one end of the reverse threaded post 35, and the retaining plate 34 is snapped into a retaining groove 33 provided at one end of the stud 31. A turntable 32 is fixedly installed at one end of the stud 31.
[0037] The first assembly component 4 includes a first slider 43. The inner sides of the first combined base 1 and the second combined base 2 are provided with stroke grooves 6. The first slider 43 is slidably installed in the stroke grooves 6. An assembly plate 41 is provided on the top surface of the first slider 43 by means of a pin. An assembly hole 42 is provided on one outer wall of the assembly plate 41.
[0038] The second assembly component 5 includes a second slider 55, which is slidably installed in the stroke groove 6. A stepped assembly platform 51 is provided on the top surface of the second slider 55 by means of a pin. An assembly hole 52 is provided on the top surface of the stepped assembly platform 51. The interior of the stepped assembly platform 51 is hollow, and a rotating groove 53 is provided on the inner side wall of the stepped assembly platform 51.
[0039] During assembly, the positions of the first assembly component 4 and the second assembly component 5 are adjusted according to the specifications of the robotic arm crossbar. The turntable 32 is rotated directly so that the reverse threaded post 35 and the assembly post 31 rotate in the same direction, so that the first assembly component 4 and the second assembly component 5 move away from or closer to each other. After the adjustment is completed, one end of the robotic arm crossbar is installed on one side of the assembly stand 41, and the other end is installed on the stepped assembly table 51 to complete the assembly. When the tooling is not in use, the clamping plate 34 is rotated to the top and the first combined base 1 and the second combined base 2 are bent directly. At this time, the assembly post 31 and the reverse threaded post 35 can automatically separate, completing the folding of the entire tooling.
[0040] like Figures 5-6 As shown, a positioning accessory 54 is rotatably installed inside the rotating groove 53. The positioning accessory 54 includes a rotating sleeve 542. The rotating sleeve 542 is rotatably installed inside the rotating groove 53 via a bottom post 543 provided at its bottom. A positioning stud 541 is threaded inside the rotating sleeve 542. A limiting shaft is horizontally fixedly installed on one side inner wall of the stepped assembly platform 51. One end of the limiting shaft is engaged in a limiting groove provided on one side outer wall of the positioning stud 541. One end of the positioning stud 541 is located in the assembly hole 52.
[0041] When positioning the robotic arm, when one end of the robotic arm is on the stepped assembly table 51, the rotating sleeve 542 is rotated directly on the outside. The positioning stud 541 on the inside of the rotating sleeve 542 can move upward until the top of the positioning stud 541 is engaged in the locking hole at the bottom of one end of the robotic arm, thus completing the further positioning of the robotic arm.
[0042] Working principle: During assembly, the positions of the first assembly component 4 and the second assembly component 5 are adjusted according to the specifications of the robotic arm crossbar. The turntable 32 is rotated directly, causing the reverse threaded post 35 and the assembly post 31 to rotate in the same direction, so that the first assembly component 4 and the second assembly component 5 move away from or closer to each other. After adjustment, one end of the robotic arm crossbar is installed on one side of the assembly plate 41, and the other end is installed on the stepped assembly table 51, completing the assembly. When the tooling is not in use, the clamping plate 34 is rotated upwards, and the first combined base 1 and the second combined base 2 are bent directly. At this time, the assembly post 31 and the reverse threaded post 35 can automatically separate, completing the folding of the overall tooling. When positioning the robotic arm, when one end of the robotic arm is on the stepped assembly table 51, the rotating sleeve 542 is rotated directly on the outside. The positioning post 541 on the inside of the rotating sleeve 542 can move upwards until the top of the positioning post 541 is engaged in the locking hole at the bottom of one end of the robotic arm, completing the further positioning of the robotic arm.
[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
