DETAILED DESCRIPTION

[0027] The application will be further described below in connection with specific embodiments, which are intended to be illustrative only and not limiting of the scope of the application.

[0029] Through the person skilled in the art, the parts in the case are connected in turn, and the specific connection and operation sequence should be referred to the working principle below. The detailed connection means is a known technology in the art, and the working principle and process are mainly introduced below.

[0030] Reference Figures 1-7 is a structural schematic diagram of the application, a mechanical arm positioning mold clamp, comprising a mechanical hand connecting plate 2 fixed on a mechanical hand, the core function of which is to realize the rigid connection of the clamp and the mechanical arm, to ensure that the movement of the mechanical arm can be accurately transmitted to the entire clamp, and to provide a stable installation reference for subsequent components, to ensure the coaxiality and position accuracy of the overall structure of the clamp. The front surface of the mechanical hand connecting plate 2 is fixed with a gripper fixing plate 1, which is the core bearing structure of the clamp, not only used for integrating and fixing product taking components, upper nut components and other key functional modules, but also able to resist vibration and stress generated by components during work through its own structural strength, to avoid the influence of force deformation on the positioning accuracy of the clamp.

[0031] The front end of the front surface of the gripper fixing plate 1 is fixed with a plurality of product taking connecting columns 3 for support, which serves to provide stable support and reasonable installation height for the profiled block fixing plate 4, so that the profiled block fixing plate 4 can be accurately aligned with the product taking-out position of the mold, and at the same time, through the distributed arrangement of multiple connecting columns, the load generated during product grabbing is evenly dispersed, preventing local stress concentration from causing component damage. The end of the product taking connecting column 3 is fixed with a profiled block fixing plate 4, which serves as the core installation carrier of the product taking assembly and is used to fix the water gap baffle, suction cup assembly, product taking limiting column and other components. Its outer shape is adapted to the product profile and can form auxiliary positioning for the product during grabbing to avoid product deviation during movement.

[0032] The profiled block fixing plate 4 is fixed with a water gap baffle 5 on both sides of the center, which is mainly used to shield the water gap structure on the product during product grabbing and transfer, preventing the water gap from colliding and scratching other components, causing damage, and at the same time preventing the residual waste at the water gap from falling and contaminating the equipment or product. The front surface of the profiled fixing plate 4 is provided with a suction cup assembly near the outer side of the water gap baffle 5, which is used to stably grab the product by negative pressure adsorption. Compared with mechanical clamping, it can reduce the extrusion and scratches on the product surface and is suitable for product grabbing with high surface precision. The suction cup assembly includes a suction cup adjusting piece 6 slidingly connected to the inside of both sides of the profiled block fixing plate 4, which serves as the installation and adjustment carrier of the suction cup. The horizontal position of the suction cup on the profiled block fixing plate 4 can be adjusted by sliding to adapt to products of different sizes or different grabbing point requirements, ensuring that the suction cup can accurately act on the best adsorption area of the product. The front surface of the suction cup adjusting piece 6 is fixed with a product taking suction cup 7, which can tightly fit the product surface during adsorption to form a stable negative pressure cavity, ensuring the uniformity and reliability of the adsorption force. At the same time, the elastic material can buffer the impact force at the moment of grabbing to avoid damaging the product surface. The side wall of the suction cup adjusting piece 6 is rotatably connected with an adjusting rod 8, which serves as a transmission component for adjusting the position of the suction cup. The adjusting rod 8 drives the suction cup adjusting piece 6 to slide in the profiled block fixing plate 4 by rotating, realizing the fine adjustment of the position of the suction cup. The threaded structure of the outer wall can provide stable transmission accuracy to prevent the position from shifting after adjustment. The end of the adjusting rod 8 penetrating the profiled fixing plate 4 is fixed with a knob 9, which provides a convenient manual adjustment interface for the operator. By rotating the knob, the adjusting rod 8 can be easily rotated without the need for special tools, making it easy to quickly adjust the position of the suction cup during equipment debugging or product replacement. In addition, the surface of the knob is usually provided with anti-slip patterns to improve the gripping stability during operation.

[0033] The strip-shaped slot is provided at the suction cup adjusting part 6 of the profiling fixed plate 4, which provides a reserved space for the sliding of the suction cup adjusting part 6, ensures smooth movement of the adjusting part, and the length and width of the slot are designed according to the adjusting range of the suction cup to limit the maximum adjusting stroke of the suction cup, avoid excessive adjustment to cause component interference, and the internal limit groove of the strip-shaped slot cooperates with the limit block to form a sliding guide structure to prevent the suction cup adjusting part 6 from rotating or deviating during sliding, ensure the straightness of the adjusting direction, and further ensure the accuracy of the position adjustment of the suction cup. The limit groove is internally connected with the limit block, which is fixedly connected with the suction cup adjusting part 6, and through the cooperation with the limit groove, the sliding track of the suction cup adjusting part 6 is accurately constrained, and at the same time, the transverse force generated when the suction cup adsorbs the product can be borne, preventing the suction cup adjusting part 6 from being inclined due to stress, and ensuring the stability of the adsorption process; the connecting part of the profiling block fixed plate 4 and the adjusting rod 8 is inserted with a sleeve, which is a supporting and guiding component of the adjusting rod 8, which can reduce the direct friction between the adjusting rod 8 and the profiling block fixed plate 4 when rotating, reduce the wear of the components, and prolong the service life. The sleeve is internally provided with a thread, which is matched with the thread on the outer wall of the adjusting rod 8, and the rotation and linear motion conversion of the adjusting rod 8 is realized through the thread engagement, which ensures the transmission accuracy when the adjusting rod 8 drives the suction cup adjusting part 6 to slide, and at the same time, the thread structure has a self-locking function, which can prevent the adjusting rod 8 from rotating by itself after adjustment, and ensures the stability of the position of the suction cup.

[0034] The front surface of the profiling fixed plate 4 is fixed with product taking limiting columns 10 at four corners. In the product grabbing process, the product is accurately positioned by contacting the corners or specific positioning holes of the product, ensuring the uniqueness of the product position on the profiling block fixed plate 4, avoiding positioning errors in subsequent processes such as milling water port and nut placement due to product adsorption deviation, and preventing product displacement due to inertia or vibration during product transfer, ensuring product posture stability. The bottom end of the front surface of the profiling fixed plate 4 is fixed with two mold closing guide columns 11. When the clamp and mold are closed and connected, they play a guiding and positioning role. By inserting the corresponding guide holes on the mold, the clamp and mold are accurately aligned, eliminating the positional deviation between the clamp and mold, ensuring the positional accuracy of the product grabbing or nut placement. At the same time, during mold closing, it can withstand part of the radial force, protecting other precision components from collision damage. The upper nut support assembly is fixed below the profiling block fixed plate 4 of the gripper fixed plate 1, serving as the installation and support structure of the upper nut assembly, providing a stable installation foundation for the nut suction assembly, upper nut limiting column and other components. Through reasonable structural layout, the upper nut assembly can accurately correspond to the nut mounting position of the mold, ensuring the accuracy of nut placement. The upper nut support assembly includes multiple upper nut connecting columns 12 fixed below the front surface of the profiling block fixed plate 4, used to connect the gripper fixed plate and the upper nut fixed plate 13. By adjusting the length of the connecting column, the installation height of the upper nut fixed plate 13 can be accurately controlled, allowing the upper nut assembly to adapt to the nut mounting depth requirements of different molds. The uniform arrangement of multiple connecting columns ensures the force balance of the upper nut fixed plate 13, preventing it from tilting during work. The end of the upper nut connecting column 12 is fixed with the upper nut fixed plate 13, which serves as the core installation carrier of the upper nut assembly, integrating components such as the upper nut limiting column, the upper nut mold closing guide column and the nut suction assembly. The flatness and parallelism accuracy of the upper nut fixed plate 13 directly affect the positional accuracy of the nut placement, so high-precision machining processes are usually used to ensure its surface accuracy. The front surface of the upper nut fixed plate 13 is fixed with upper nut limiting columns 14 at four corners. During nut placement, the circumferential and radial positions of the nut are accurately constrained to prevent the nut from shifting or flipping during transfer or placement, ensuring that the nut falls into the nut mounting hole of the mold in the correct attitude. The limiting column also provides auxiliary positioning when the nut suction assembly adsorbs the nut, enhancing the stability of adsorption. The inner side of the upper nut fixed plate 13, located below the upper nut limiting column 14 at the bottom, is fixed with the upper nut mold closing guide column 15. When the clamp and mold are connected for nut placement, it plays a guiding and positioning role. By cooperating with the guide holes on the mold, the upper nut assembly and the nut mounting position of the mold are accurately aligned, eliminating positional deviation and ensuring that the nut can be smoothly and accurately placed into the mounting hole, avoiding nut jamming or damaging the mold due to inaccurate positioning.The center of the gripper fixing plate 1 is symmetrically fixed with a guide pipe 16 as a sliding guide and support component of the sliding rod 17. The high-precision processing of the inner wall of the guide pipe 16 can ensure the straightness of the sliding rod 17 when sliding, avoid the sliding rod 17 from shaking or deviating, and at the same time provide protection for the sliding rod 17 to prevent external impurities from entering and affecting the sliding precision. The guide pipe 16 is internally connected with the sliding rod 17 as a transmission component of the buffer pressure head 18, which can drive the buffer pressure head 18 to move axially. When the clamp and the mold are docked, the impact force at the docking moment is absorbed through the extension and retraction of the sliding rod 17. At the same time, the position of the buffer pressure head 18 can be adaptively adjusted according to the change of the docking position. The end of the sliding rod 17 is fixed with the buffer pressure head 18, which directly contacts the mold or product and plays a buffering and protecting role during the docking process. The end is usually designed with elastic material or circular arc transition to avoid rigid collision with the mold and product, which can cause surface damage. At the same time, the pressure can be evenly transmitted through the contact area to prevent excessive local stress. The buffer elastic adjusting piece is fixed between the buffer pressure head 18 and the gripper fixing plate 1. The impact force when the clamp and the mold are docked is absorbed through elastic deformation to reduce the influence of vibration on the clamp and the mold. At the same time, by adjusting the elastic parameters, the grasping and docking requirements of products of different weights and different materials can be adapted to ensure the rationality of the buffering effect.

[0035] The inside of the guide pipe 16 is symmetrically provided with a limiting groove which cooperates with the convex rib on the sliding rod 17 to precisely constrain the sliding track of the sliding rod 17, prevent the sliding rod 17 from rotating during sliding, and ensure that the buffer pressure head 18 always maintains the correct posture and contacts the mold and product, avoiding docking deviation caused by the rotation of the sliding rod. The inside of the limiting groove is slidably connected with the convex rib which is connected with the two side walls of the sliding rod 17. It not only prevents the sliding rod 17 from rotating, but also enhances the connection stability between the sliding rod 17 and the guide pipe 16, bears the radial force generated by the sliding rod 17 during axial movement, and avoids deformation of the sliding rod 17 due to stress. Moreover, the outer wall of the sliding rod 17 is composed of a smooth rod and a thread. The smooth rod part ensures smooth sliding of the sliding rod 17 in the guide pipe 16, reduces friction resistance, and the thread part provides an installation and adjustment interface for the buffer elastic adjusting piece, which is convenient for adjusting the position of the buffer elastic adjusting piece through the thread structure, and further changing the pre-tightening force of the buffer spring.

[0036] The buffer elastic adjusting part comprises an elastic adjusting part 19 threadedly connected at the thread of the slide rod 17, which is used as an adjusting component of the pre-tightening force of the buffer spring, and can be moved along the axial direction of the thread of the slide rod 17 by rotating the elastic adjusting part 19, so as to change the position of a spring pressing plate 20 and realize the adjustment of the compression amount of the buffer spring 22, thereby adapting to the buffer requirement under different impact loads and ensuring the stability and reliability of the buffer effect. The bottom end of the elastic adjusting part 19 is rotationally connected with the spring pressing plate 20, which is used for bearing the pressure of the buffer spring 22 and transmitting the adjusting force of the elastic adjusting part 19 to the buffer spring 22. The flatness accuracy of the spring pressing plate 20 directly affects the uniformity of the force borne by the buffer spring 22, so as to avoid the uneven force borne by the spring due to the inclination of the pressing plate and affect the buffer effect. The bottom end of the spring pressing plate 20 is attached with the buffer spring 22, which is used as the core elastic element of the buffer elastic adjusting part. The buffer spring 22 absorbs the impact force when the clamp is docked through its compression and rebound, reduces the influence of vibration on the clamp, the mold and the product, and ensures that the spring still has stable elastic performance when bearing the maximum impact. The buffer spring 22 is sleeved with a dust cover 21 outside, which is used for preventing external dust, debris and other impurities from entering the inside of the buffer spring 22, avoiding the influence of impurities on the extension performance of the spring, protecting the spring from external collision damage and prolonging the service life of the spring. The connection between the elastic adjusting part 19 and the spring pressing plate 20 is connected through an annular rotating block, so that the spring pressing plate 20 remains stationary when the elastic adjusting part 19 is rotated, avoiding the rotation of the spring pressing plate 20 with the elastic adjusting part 19, which causes the buffer spring 22 to twist, ensuring that the buffer spring is always in an axial stress state and ensuring the buffer effect. The outer wall of the annular rotating block is fixed with a limiting rib, which cooperates with the corresponding structure on the guide pipe 16 or the gripper fixed plate 1 to prevent the axial displacement of the annular rotating block during rotation, ensure that the adjusting force of the elastic adjusting part 19 can be accurately transmitted to the spring pressing plate 20, and avoid the loss or deviation of force during the adjustment process.

[0037] When the present application is used: Firstly, the mechanical hand connecting plate 2 is used as the connection hub of the clamp and the mechanical arm, accurately transmits the movement of the mechanical arm to the overall clamp, provides a stable installation reference for the gripper fixed plate 1, ensures the position accuracy and coaxiality of the subsequent functional modules, and the gripper fixed plate 1 is used as the core bearing structure, integrates the product taking assembly and the upper nut assembly, offsets the vibration and stress in the operation process by relying on its own structural strength, and avoids the influence of the deformation of the clamp on the accuracy.

[0038] In the product taking link, the product taking connecting column 3 provides a support height for the product taking profiled block fixed plate 4 to adapt to the mold taking position, and the profiled block fixed plate 4 is supported by the structure matched with the product contour, and cooperates with the two side water gap baffles 5 to realize the protection of the product water gap, so as to prevent the water gap from being damaged or contaminated by waste materials during the transfer; the suction cup assembly acts on the product surface through negative pressure adsorption, wherein the suction cup adjusting part 6 can slide along the strip-shaped slot of the profiled block fixed plate 4, the operator drives the adjusting rod 8 through the knob 9, and the adjusting rod 8 is guided and constrained by the limiting groove and the limiting block, so that the product taking suction cup 7 is accurately adjusted to the best adsorption area of the product, the product taking suction cup 7 made of elastic material forms a stable negative pressure cavity at the same time, buffers the grabbing impact force, avoids the damage to the product surface, and the threaded cooperation between the adjusting rod 8 and the sleeve ensures the self-locking of the position after adjustment, so as to prevent deviation.

[0039] The product limiting column 10 further constrains the product corners or positioning holes to ensure the unique position of the product on the profiled block fixed plate 4, and the mold closing guide column 11 is inserted into the mold guide hole when the clamp is connected with the mold, so as to eliminate the position deviation and ensure the accuracy of the taking.

[0040] In addition, the guide pipe 16 in the center of the gripper fixed plate 1 provides linear sliding constraint for the sliding rod 17, the sliding rod 17 drives the buffer pressure head 18 to adaptively stretch and contract when the clamp is connected with the mold, the buffer elastic adjusting part adjusts the position of the spring pressure plate 20 through the elastic adjusting part 19, changes the pre-tightening force of the buffer spring 22, so as to adapt to different impact loads, the buffer spring 22 absorbs the connection impact force through compression and rebound, and the dust cover 21 protects the spring from impurities, and the cooperation of the annular rotating block and the limiting convex rib ensures that the spring pressure plate 20 does not move with the elastic adjusting part 19 when the elastic adjusting part 19 rotates, so as to ensure the stable transmission of the buffer force, and the whole realizes the efficient, accurate and low-damage mold operation process.
