Description

Technical Field

[0001] This utility model relates to the field of nut-burying equipment, and in particular to an automatic nut-burying equipment. Background Technology

[0002] Fully automatic nut embedding equipment is a highly automated mechanical device used in industrial production. It is primarily used to precisely embed metal nuts into preset positions on workpieces made of plastic, metal, or composite materials. This equipment typically consists of an automatic feeding system, a precision positioning mechanism, a heating or pressing module, and an intelligent control system. Through a PLC or CNC system, it achieves fully automated operation, automatically completing processes such as nut sorting, positioning, heating (e.g., hot-melt embedding), pressing, and quality inspection. It is widely used in mass production fields such as automotive parts, appliance housings, and electronic equipment.

[0036] The clamping sleeve 4 includes a fixing block 41. A first clamping sleeve 42 is fixed to the outer side of the fixing block 41. A second clamping sleeve 43 is installed on the outer side of the movable frame 3. A support spring 44 is provided on one inner wall of the second clamping sleeve 43. One end of the support spring 44 is connected to a limit pad 45. A clamping plate 46 is fixed to one side of the limit pad 45. A guide connecting post 47 is fixed to the outer side of the limit pad 45. A handle pad 48 is fixed to one end of the guide connecting post 47. A metal nut 49 is threaded to the outer side of the guide connecting post 47. A through hole is provided inside the second clamping sleeve 43. The size of the through hole is adapted to the size of the clamping plate 46, allowing the clamping plate 46 to move normally. The outer side of the metal nut 49 is provided with anti-slip texture. The handle pad 48 and the guide connecting post 47 are bonded and fixed together, which makes it easy for the user to rotate the metal nut 49. The inside of the second clamping sleeve 43 is provided with a limit hole. The size of the limit hole is adapted to the size of the guide connecting post 47, which can guide and limit the guide connecting post 47. One end of the support spring 44 is fixedly connected to the limit pad 45, and the other end of the support spring 44 is fixedly connected to the inner wall of the second clamping sleeve 43.

[0037] The limiting mechanism 9 includes a fixed sleeve 91, a limiting sleeve 92 fixed to the top of the fixed sleeve 91, a fixed threaded post 93 fixed to the outer side of the first electric push rod 2, a limiting nut 94 threadedly connected to the outer side of the fixed threaded post 93, a cast iron block 95 fixed to the outer side of the first electric push rod 2, a cast iron rod 96 fixed to the outer side of the cast iron block 95, a rotating plate 97 connected to the outer side of the cast iron rod 96 via a bearing, a supporting threaded post 98 fixed to the outer side of the first electric push rod 2, a metal threaded sleeve 99 threadedly connected to the outer side of the supporting threaded post 98, the outer side of the first electric push rod 2 fitting against the inner wall of the limiting sleeve 92, and an arc-shaped groove adapted to the size of the supporting threaded post 98 opened on the outer side of the rotating plate 97.

[0038] Working Principle: When clamping and moving a workpiece, the corresponding workpiece is placed between the first clamping sleeve 42 and the second clamping sleeve 43. When a workpiece with slight dimensional deviations is placed, the support spring 44 inside the second clamping sleeve 43 provides elastic force to push the limiting pad 45, allowing the limiting pad 45 to drive the clamping plate 46 to move. The corresponding surface of the clamping plate 46 can fit against the outside of the workpiece with slight dimensional deviations. Moreover, the guide connecting post 47 plays a guiding role, and the metal nut 49 plays a limiting role. The elasticity of the support spring 44 allows the clamping plate 46 to automatically adjust the clamping force when contacting the workpiece, adapting to workpieces of different sizes or with slight dimensional deviations, reducing the stringent requirements for positioning accuracy. Furthermore, if the workpiece experiences slight vibration or displacement, the spring's buffering effect can prevent rigidity. The system protects the nut and workpiece surface from impact. By setting a limiting mechanism 9, when the first electric push rod 2 is fixed on the top of the fixed sleeve 91, the fixed threaded post 93 on the outside of the first electric push rod 2 is movably inserted into the limiting sleeve 92. Then, the limiting nut 94 and the fixed threaded post 93 are threadedly connected. Subsequently, the rotating plate 97 on the outside of the cast iron rod 96 is rotated so that the rotating plate 97 is movably sleeved on the outside of the supporting threaded post 98. After the metal threaded sleeve 99 and the supporting threaded post 98 are threadedly connected, the corresponding surface of the metal threaded sleeve 99 is tightly attached to the outside of the rotating plate 97, which facilitates the positioning of the first electric push rod 2 during assembly. The limiting sleeve 92 and the rotating plate 97 limit and reinforce the outside of the first electric push rod 2 to ensure that the first electric push rod 2 is assembled stably and does not loosen.

[0039] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
