[0029] The following is combined with Figure 1-Figure 5 This application is described in further detail.

[0030] The embodiments of the present application disclose an automatic hydraulic stretcher for a robot.

[0031] Reference Figure 1-3 The automatic hydraulic stretcher for a robot includes a hydraulic stretcher body 1, an oil inlet 2 provided on the hydraulic stretcher body 1, a first mounting ring 3 and a second mounting ring 4 provided on the hydraulic stretcher body 1, a connecting portion 5 provided on one side of the hydraulic stretcher body 1, a stretching plate 6 provided at one end of the connecting portion 5, a connecting mechanism provided on the outer surface of one side of the first mounting ring 3 and the second mounting ring 4, and a positioning mechanism provided on the connecting mechanism;

[0032] Among them, the connecting mechanism includes a mounting box 8 fixedly mounted on the outer surface of one side of the second mounting ring 4, a connecting frame 7 fixedly mounted on the outer surface of one side of the first mounting ring 3, a gear 16 rotatably mounted in the mounting box 8, and two rack plates 15 meshing with the gear 16 are symmetrically slidably mounted in the mounting box 8, a same positioning plate 18 fixedly mounted on the two rack plates 15 away from each other on one side outer wall, a synchronization rod 17 fixedly mounted on one end of the gear 16, a turbine 12 fixedly mounted on the synchronization rod 17, and a worm 13 meshing with the turbine 12 is rotatably mounted on one side inner wall of the mounting box 8, a first knob 14 fixedly mounted on one end of the worm 13, two card slots 19 opened on the outer walls of the two connecting frames 7 close to each other on one side, two card blocks 20 slidably mounted in the two card slots 19, and the two card blocks 20 are fixedly connected to the corresponding positioning plates 18, two mounting slots 9 symmetrically opened on the mounting box 8, and the two connecting frames 7 are slidably mounted in the corresponding mounting slots 9.

[0033] When in use, by turning the first knob 14, the first knob 14 rotates and drives the worm 13 to rotate, the worm 13 rotates, thereby driving the turbine 12 and the gear 16 to rotate, the gear 16 rotates and drives the two rack plates 15 and the two positioning plates 18 to move away from each other, and the two positioning plates 18 move away from each other to install and fix the two connecting frames 7, thereby completing the installation and fixation of the first mounting ring 3 and the second mounting ring 4, and completing the assembly of the automatic hydraulic stretcher, further improving the convenience and flexibility during installation.

[0034] Reference Figure 2-5The positioning mechanism includes a protective box 10 fixedly mounted on the outer wall of one side of the installation box 8, a box door 11 hinged on one side of the protective box 10, and the side of the protective box 10 close to the installation box 8 is open, and the first knob 14 is wrapped inside, a fixing screw 22 screwed on the box door 11, a limiting plate 21 fixedly mounted on one end of the fixing screw 22, a second knob 25 fixedly mounted on the other end of the fixing screw 22, a plurality of limiting holes 23 opened on the first knob 14, and a plurality of limiting columns 24 slidably mounted in the plurality of limiting holes 23, and the plurality of limiting columns 24 are all fixedly connected to the limiting plate 21.

[0035] During use, by rotating the second knob 25, the second knob 25 rotates, thereby driving the fixing screw 22 to rotate as well, and driving the limit plate 21 to move. The movement of the limit plate 21 causes multiple limit columns 24 to be inserted into the corresponding limit holes 23, thereby completing the positioning and installation of the first knob 14, thereby preventing the first knob 14 from rotating on its own, and improving the stability and safety during installation and fixation.

[0036] The implementation principle of the automatic hydraulic stretcher for robots in the embodiment of the present application is as follows: when in use, the first mounting ring 3 and the second mounting ring 4 are spliced together, so that the two connecting frames 7 are inserted into the corresponding mounting grooves 9, and then the first knob 14 is rotated. The first knob 14 rotates and drives the worm 13 to rotate. The rotation of the worm 13 drives the turbine 12 and the gear 16 to rotate. The gear 16 rotates and drives the two rack plates 15 and the two positioning plates 18 to move away from each other. The two positioning plates 18 move away from each other and then install and fix the two connecting frames 7. Therefore, the installation and fixation of the first mounting ring 3 and the second mounting ring 4 can be completed, and the assembly of the automatic hydraulic stretcher is completed, further improving the convenience and flexibility during installation.

[0037] By rotating the second knob 25, the rotation of the second knob 25 will drive the fixing screw 22 to rotate as well, and drive the limit plate 21 to move. The movement of the limit plate 21 will cause multiple limit columns 24 to be inserted into the corresponding limit holes 23, thereby completing the positioning and installation of the first knob 14, thereby preventing the first knob 14 from rotating on its own, and improving the stability and safety during installation and fixation; when it is necessary to use an automatic hydraulic tensioner for a robot, the external force is directly applied to the bolt by using the hydraulic cylinder, so that it is stretched in the elastic deformation zone, and the bolt diameter is slightly deformed, so that the nut is easy to loosen. After the oil pressure in the hydraulic tensioner is removed, the nut and the joint surface are tightly attached, thereby locking the axial deformation of the bolt, that is, locking the remaining bolt load in the nut.

[0038] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
