[0021] like Figures 1 to 4As shown, the technical solution of this utility model relates to a fixture, including: a base plate 100; a support column 200 disposed on the base plate 100, the upper end of the support column 200 having an inner cavity 210, the support column 200 being used to place a product 600; a clamping mechanism 300 disposed on the base plate 100, the clamping mechanism 300 being used to restrict the product 600 on the support column 200, preventing the product 600 from shifting or shaking during assembly; a guide column 400 movably disposed in the inner cavity 210 of the support column 200 in the vertical direction, the guide column 400 being used to provide guidance for the nut 700, ensuring that the nut 700 can accurately and vertically enter the mounting hole of the product 600; and a reset member 500 disposed in the inner cavity 210, with its upper end abutting against the guide column 400, the reset member 500 being used to drive the guide column 400 to reset, preparing for the next assembly.

[0022] The application of the above-mentioned fixture has at least the following beneficial effects: When using this fixture to assemble the nut 700, the operator first places the product 600 on the support column 200, so that the guide column 400 extends from the mounting hole on the product 600 where the nut 700 needs to be installed. Then, the clamping mechanism 300 is used to clamp and restrict the product 600 onto the support column 200 to prevent it from shaking during assembly. The nut 700 to be installed is then placed along the guide column 400, allowing it to slide down along the guide column 400 to above the mounting hole. The nut 700 is then tightened using a pneumatic screwdriver. When screwed into the mounting hole, the guide post 400 is pressed down by the pneumatic screwdriver during the screwing process. It moves downward synchronously with the downward movement of the nut 700 and compresses the reset piece 500, thus providing space for the downward movement of the pneumatic screwdriver. The guide post 400 always plays a directional guiding role for the nut 700 throughout the assembly process, effectively preventing the nut from tilting during screwing. After the assembly is completed, the pneumatic screwdriver is withdrawn, and the guide post 400 automatically resets upward under the elastic restoring force of the reset piece 500, returning to its initial position, which is convenient for the next assembly.

[0023] According to some embodiments of this utility model, the upper end of the guide post 400 is provided with a conical guide portion 410. When installing a nut 700 that matches the diameter of the guide post 400, the guide portion 410 guides the nut 700 into the guide post 400, so that the nut 700 can be placed into the guide post 400 more smoothly. The corresponding placement operation can be completed without precise positioning, which reduces the requirements for placement accuracy and improves assembly efficiency.

[0024] According to some embodiments of the present invention, the upper end of the guide part 410 is provided with a rounded chamfer. By providing the rounded chamfer, the nut 700 placed in the guide post 400 can be given room and protected, reducing the impact of sharp edges when in contact with the nut 700, avoiding scratches or damage to the surface of the nut during placement, and protecting the appearance of the nut.

[0025] According to some embodiments of this utility model, the upper end face of the support column 200 is provided with a limiting plate 220, the limiting plate 220 is provided with a clearance hole 221 for avoiding the guide column 400, and the lower end of the guide column 400 is provided with a flange 420, the diameter of the flange 420 is larger than the diameter of the clearance hole 221. The limiting plate 220 can support the lower end of the product 600, and also provide a limiting function when the nut 700 continues to move downward. When the limiting structure of the product 600 for the nut 700 fails during the downward tightening process, the limiting plate 220 can prevent the nut 700 from moving downward excessively, ensuring that the nut is always in the predetermined position inside the product 600.

[0026] According to some embodiments of this utility model, the reset member 500 is a spring, with its two ends abutting against the lower inner wall of the inner cavity 210 and the lower end of the guide post 400, respectively. When the pneumatic screwdriver tightens the nut 700, the pneumatic screwdriver withdraws from the installation area, and the restoring force of the spring pushes the guide post 400 upward, causing it to extend out of the product 600 again, thus guiding the installation of the nut 700 on the product 600 for the next time. In other embodiments, the reset member 500 can be a spring sheet, which can elastically extend and retract.

[0027] According to some embodiments of this utility model, two support columns 200 may be provided, respectively arranged on both sides of the clamping mechanism 300. This symmetrical arrangement helps to improve the support stability of the product 600. In other embodiments, multiple support columns may be provided according to the shape of the product 600 and the support requirements to enhance adaptability and support effect.

[0028] Regarding the connection method between the support column 200 and the base plate 100, a threaded structure can be used to achieve a detachable connection, facilitating adjustment or replacement of the support column. Alternatively, a magnetic connection structure can be used, for example, by setting a first magnetic attraction part on the base plate 100 and a second magnetic attraction part at the lower end of the support column 200, enabling quick installation and positioning through magnetic force, and facilitating adjustment of the support column's position according to different products.

[0029] According to some embodiments of this utility model, the clamping mechanism 300 is configured as a vertical quick clamp, which is a mechanical device used for clamping and positioning workpieces. Its core structure includes components such as a pressure handle, a handle, a connecting rod, and a spring mechanism. The clamp body is made of Q235 steel and has adjustable clamping force and opening angle. A self-locking function is achieved through the cooperation of the locking handle and the spring. The vertical quick clamp allows for manual and rapid clamping or releasing of the product 600. It is convenient to operate, has stable clamping force, and is self-locking, improving clamping reliability.

[0030] It should be noted that in this specification, terms such as "one embodiment", "some embodiments", "basic embodiment", and "extended embodiment" may be used to describe several embodiments of the present invention, and the specific features, structures, materials or characteristics of the several embodiments may be combined in accordance with the principles and spirit of the present invention.

[0031] Although some embodiments of the present invention have been shown and described in this specification, the present invention should not be limited to the above embodiments. As long as they achieve the technical effects of the present invention by the same or equivalent means, any changes, modifications, equivalent substitutions and equivalent variations of these embodiments within the spirit and principles of this disclosure, without departing from the principles and purpose of the present invention, should be included within the scope of protection of this disclosure and should be considered to fall within the protection scope of the present invention.
