Detailed Implementation

[0018] like Figures 1 to 4 As shown, a fixture for automatic hinge assembly includes a mounting base 10 with a main mounting surface 11 on its surface. A mounting body 20 is mounted on the main mounting surface 11 by fasteners. The mounting base 10 has a plurality of guide pin sliders 30. The bottom of the mounting body 20 has a plurality of slider connecting grooves 21 recessed therein. The front ends of the plurality of guide pin sliders 30 are slidably connected to the plurality of slider connecting grooves 21. The interior of the mounting body 20 has a plurality of pin-stop mounting grooves 22, in which pin-stop sliders 40 are movably mounted. The upper ends of the plurality of guide pin sliders 30 are respectively connected to guide pins 31. The plurality of guide pins 31 and the plurality of pin-stop sliders 40 are arranged in a one-to-one correspondence. In use, by pushing the guide pin sliders 30, the guide pins 31 are driven to move, guiding the needle threading operation, ensuring the needle threading pass rate and improving product stability. This fixture effectively prevents needle drop during assembly through the needle-stopping slider 40 structure; the guide needle slider 30 and the guide needle 31 structure can be adjusted with the fixture to adapt to changes in equipment level tolerance, effectively preventing unstable needle threading, thereby ensuring product quality and reducing the defect rate caused by assembly errors.

[0019] In practical implementation, a stop 23 is installed on the upper side of the mounting body 20. The stop 23 is connected and fixed to the mounting body 20 by fasteners. The mounting body 20 has a positioning mounting groove 24 inside. A positioning block 25 is fixedly installed in the positioning mounting groove 24 by fasteners. In use, the positioning block 25 and the stop 23 can be adapted to different sizes and shapes of the hydraulic hinge to effectively limit the assembly of the parts, improve assembly accuracy and efficiency, and prevent the parts from shifting position during the assembly process.

[0020] In specific implementation, the side of the mounting body 20 is provided with a positioning plate slot 26, and a spring positioning plate 27 is installed in the positioning plate slot 26. The surface of the spring positioning plate 27 is recessed with a plurality of first spring grooves 271, and the bottom of a plurality of pin-stopping sliders 40 is respectively recessed with second spring grooves 41. A push spring 50 is connected between the first spring grooves 271 and the second spring grooves 41. The upper side of the stop member 23 is provided with a plurality of positioning through holes 231, and the front ends of a plurality of guide pins 31 are connected through a plurality of positioning through holes 231. The upper ends of a plurality of pin-stopping sliders 40 are respectively recessed with pin-stopping recesses 42. A plurality of guide pins 31 and a plurality of pin-stopping recesses 42 are respectively set one-to-one. During use, when the guide pin slider 30 is pushed to drive the guide pin 31 to move, the front end of the guide pin 31 moves along the positioning through hole 231 and is finally positioned on the corresponding pin-stopping recess 42. With the help of the elastic action of the push spring 50, after the needle is loaded, the needle block slider 40 automatically rises, so that the needle block structure can effectively block the product pin, thereby preventing the pin from falling off in the subsequent production process, avoiding equipment jamming or machine stoppage caused by the pin falling off, significantly reducing the product defect rate and improving assembly stability.

[0021] In practical implementation, the front ends of several guide pin sliders 30 are respectively connected to limit blocks 32. The limit blocks 32 are connected and fixed to the guide pin sliders 30 by fasteners. In use, by setting the limit blocks 32, the movement range of the guide pin sliders 30 can be effectively limited during the pushing process, preventing it from exceeding the predetermined stroke, and ensuring that the guide pin 31 is always within the controllable trajectory during the assembly process, thereby improving the stability and accuracy of needle insertion, further ensuring the assembly quality and extending the service life of the fixture.

[0022] In practical implementation, a locking bracket 60 is fixedly installed on the side of the mounting body 20 by fasteners. The upper part of the locking bracket 60 is provided with a slider slot 61 and a pressure plate slot 62. The pressure plate slot 62 is located above the slider slot 61. A transmission slider 63 is connected in the slider slot 61, and a pressure plate member 64 is connected in the pressure plate slot 62. A transmission S-groove 631 is provided on the surface of the transmission slider 63, and a pressure plate through hole 641 is provided on the surface of the pressure plate member 64. Fasteners are connected to the transmission S-groove 631 through the pressure plate through hole 641. In use, when the transmission slider is pushed, the curved guide structure of the transmission S-groove can drive the pressure plate member to perform a locking or releasing action, thereby realizing the functions of pressing and positioning the product and quick release. The operation is convenient and efficient, improving assembly efficiency and reliability.

[0023] In summary, the mounting base 10 has a mounting body 20 mounted on its surface. The mounting base 10 has several guide pin sliders 30. The bottom of the mounting body 20 has several slider connecting grooves 21 recessed therein. The front ends of the guide pin sliders 30 are slidably connected to the slider connecting grooves 21. The interior of the mounting body 20 has several pin-stop mounting grooves 22, in which pin-stop sliders 40 are movably mounted. The upper ends of the guide pin sliders 30 are connected to guide pins 31. A spring positioning plate 27 is installed in the positioning plate slot 26. A push spring 50 connects the spring positioning plate 27 and the pin-stop slider 40. This utility model's fixture for automatic hinge assembly can effectively improve the assembly efficiency and accuracy of hydraulic hinges, ensuring product assembly quality. It also has good versatility, suitable for the assembly needs of various types of hydraulic hinges of the same type. By setting up a guide needle structure, the accuracy of needle threading is improved and the instability of needle threading is prevented.
