Specific embodiments

[0024] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific embodiments, structures, features and their effects of the present invention as follows.

[0025] Please refer to Figures 1-6 As shown, this embodiment provides a tripod automatic line torque detection device, including a base 1. An installation frame 2 is fixedly installed on the top of the base 1. A lifting frame 3 is slidably installed inside the installation frame 2. An electric telescopic rod for driving the lifting frame 3 to move up and down in the vertical direction is installed on the installation frame 2. A gear 4 is rotatably installed on the lifting frame 3. Two rack plates 5 respectively meshing with both sides of the gear 4 are slidably installed on the lifting frame 3. The top of one of the rack plates 5 is fixedly installed with a chute plate 1. A rotating plate 7 is rotatably installed at a position corresponding to directly above the gear 4 on the lifting frame 3. A driving motor for driving the rotating plate 7 to rotate is installed on the lifting frame 3. One end of the rotating plate 7 away from the rotating shaft is slidably connected through the chute plate 1. Displacement sensors 8 are fixedly installed on the same side of the lifting frame 3 corresponding to the two rack plates 5. An electronic screen 9 for receiving the signals of the two displacement sensors 8 is fixedly installed on the installation frame 2;

[0026] When the rotating plate 7 rotates in one direction, it will drive one of the rack plates 5 to slide through the chute plate one 6. When the sliding bar plate slides, it will drive the other rack plate 5 to move in the opposite direction through the gear 4, resulting in a phenomenon that one rack plate 5 moves towards the displacement sensor 8 and the other rack plate 5 moves away from the displacement sensor 8. The rack plate 5 moving towards the displacement sensor 8 will squeeze the output end of the displacement sensor 8, so that the displacement sensor 8 transmits the distance of the displacement of the rack plate 5 to the electronic screen 9 in the form of a signal to obtain the radian of the rotation of the gear 4;

[0027] Please refer to Figures 1-5 As shown, a mounting box 10 is fixedly installed at the bottom end of the rotating shaft of the gear 4. A plurality of clamping rods 11 are slidably installed through the bottom of the mounting box 10. A pressing plate 12 is fixedly installed at the tops of the plurality of clamping rods 11 at the same time. A plurality of springs 13 are fixedly installed between the pressing plate 12 and the top of the inner cavity of the mounting box 10. A rubber ring 14 is fixedly installed at the bottom of the mounting box 10 corresponding to the positions of the plurality of clamping rods 11. When the bottom of the mounting box 10 abuts against the top of the tripod, the rubber ring 14 is used to weaken the rigid contact between the two;

[0028] The mounting box 10 rotates synchronously with the gear 4 and moves up and down synchronously with the lifting frame 3. When the mounting box 10 drives the plurality of clamping rods 11 to insert into the test holes of the tripod, when the bottom ends of the clamping rods 11 abut against the tripod, the clamping rods 11 will drive the pressing plate 12 to squeeze the plurality of springs 13 upwards, so that the springs 13 are compressed and thus in a stressed state to correct the displacement error of the clamping rods 11 moving into the test holes of the tripod and prevent the tripod and the clamping rods 11 from damaging each other. When the clamping rods 11 are disengaged from the test holes on the tripod, the stressed state of the springs 13 is released, and the springs 13 will drive the pressing plate 12 to rebound to the initial state to drive the plurality of clamping rods 11 to displace to the initial position;

[0029] Please refer to Figure 1 、 Figure 2 and Figure 4As shown in the figure, a displacement plate 15 is slidably installed through the top of the base 1. An electric telescopic rod for driving the displacement plate 15 to move back and forth is installed on the base 1. The top of the displacement plate 15 is bolted with a tooling plate 16. The top of the tooling plate 16 is rotatably installed with a positioning plate 17 adapted to the tripod. The top of the tooling plate 16 is fixedly installed with a plurality of positioning rods 18 adapted to the tripod. A second chute plate 19 is fixedly installed on the positioning rod 18. The top of the displacement plate 15 is fixedly installed with a plurality of equally spaced support plates 20. A slide plate 21 is slidably installed through the support plate 20. A clamping plate 22 is fixedly installed on one side of the plurality of slide plates 21 facing each other. The side of the clamping plate 22 away from the slide plate 21 is made of rubber material. A folding plate 23 is slidably installed on the second chute plate 19. Two ends of the folding plate 23 are respectively rotatably connected to two adjacent clamping plates 22. An electric push rod for driving one of the slide plates 21 to move is installed on the support plate 20;

[0030] When one of the slide plates 21 moves towards the center position of the tooling plate 16, it will drive the folding plate 23 to slide on the second chute plate 19, so as to drive another clamping plate 22 rotatably connected thereto to move synchronously with this clamping plate 22 towards the center position of the work plate. And the folding plate 23 will rotate in response to the change in the position between the clamping plate 22 and the second chute plate 19 to correct the position change among the clamping plate 22, the folding plate 23 and the second chute plate 19.

[0031] When the present invention is in use, first, the multiple mounting holes of the tripod to be tested are respectively aligned with the multiple positioning rods 18 and passed through the multiple positioning rods 18, and the positioning plate 17 is rotated to a position corresponding to the test hole of the tripod, and the test hole of the tripod is fixed on the positioning plate 17. Then, the distance between the multiple clamping plates 22 is reduced, so that the multiple clamping plates 22 abut against the outer peripheral wall of the tripod, thereby fixing the tripod installed on the tooling plate 16. After the above operations are completed, the tripod is moved to a position corresponding to the bottom of the installation box 10 through the displacement plate 15. Then, the lifting frame 3 drives the installation box 10 to move downward until the installation box 10 drives the multiple clamping rods 11 to insert into the test holes at the top of the tripod. Then, first, the rotating plate 7 is rotated clockwise, so that the rotating plate 7 drives one of the rack plates 5 to reciprocate through the chute plate, so that the rack plate 5 drives the other rack plate 5 to move towards each other through the gear 4. At this time, after the gear 4 rotates a certain angle clockwise from the starting point, the gear 4 will reciprocate within this angle, so as to drive the installation box 10 to rotate synchronously, so that the installation box 10 performs a torque test on the tripod clockwise through the clamping rod 11. During this period, the maximum torque value measured for the tripod clockwise will be transmitted to the electronic screen 9 through the displacement sensor 8. The same applies when the rotating plate 7 rotates clockwise.

[0032] The above are only the preferred embodiments of the present invention and do not impose any formal limitations on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments with equivalent changes within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
