Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal part claw welding technology, specifically a spherical metal part claw welding mechanism. Background Technology
[0002] Some existing assembly work mainly involves assembling spherical metal parts onto plastic parts. The inner periphery of the spherical metal parts has multiple metal claws that assemble with the plastic parts. Many spherical metal parts or spherical metal mesh covers have claws welded inside, requiring no traces on the front. This requires laser welding. Welding metal claws or other structures on the back is also necessary because laser welding can only be done perpendicular to the welding surface. Therefore, the weld point of the spherical part needs to be perpendicular to the laser beam. In this position, the spherical part needs to be rotated and tilted. Existing equipment is not convenient for pre-positioning the claws and for sequential and rapid welding. Utility Model Content

[0009] The effect achieved by the above components is that, with the cooperation of the positioning holes, the positioning pin restricts the relative movement and rotation between the base and the upper pressure plate, thereby achieving the purpose of precise positioning and cooperation between the base and the upper pressure plate, increasing the stability of the connection between the two, and improving the accuracy of positioning the spherical metal parts.
[0010] Preferably, a rotary drive assembly for driving the upper pressure plate and the base to rotate is installed on one side of the top of the base.

[0020] Secondly, this utility model achieves position positioning by using an assembly block within an assembly hole, with the slot initially limiting the position of the chuck, and the ball screw securing the chuck in the slot through elastic force.

[0028] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.
[0029] This utility model provides an improved welding mechanism for spherical metal parts with claws. The technical solution of this utility model is as follows:
[0030] In embodiments of this utility model, such as Figures 1-4 As shown, a spherical metal part claw welding mechanism includes an inclined support assembly. A base 4 is rotatably mounted on the inclined support assembly. The inclined support assembly includes an inclined pad 1, a base 2 mounted on the inclined pad 1, a support plate 3 mounted on the base 2, and a guide post 10 mounted at the center of the support plate 3. The base 4 is fixed on the guide post 10. The inclined pad 1 creates an inclined angle for the entire installation structure. The base 2 and support plate 3 ensure structural stability. The guide post 10 ensures the coaxiality of the base 4 during rotation, thus providing stable inclined support and precise rotation guidance for the base 4. The base 4 has a slot for mounting the spherical metal part. An upper pressure plate 7 for positioning the spherical metal part is mounted on the base 4. Multiple sets of corresponding positioning holes are opened between the base 4 and the upper pressure plate 7. Positioning pins 11 are installed in the positioning holes. With the cooperation of the positioning holes, the relative movement and rotation between the base 4 and the upper pressure plate 7 are restricted, and the purpose of precise positioning and cooperation between the base 4 and the upper pressure plate 7 is achieved. The upper pressure plate 7 has multiple annularly distributed assembly holes 8. A claw assembly 9 for fixing the claw is slidably inserted into the assembly holes 8. The claw assembly 9 includes an assembly block 91 slidably inserted into the assembly holes 8. The bottom end of the assembly block 91 is fitted with a slot 92 for placing the claw. A screw hole 93 extending into the slot 92 is opened on the outside of the assembly block 91. A ball screw 94 for abutting the claw is installed in the screw hole 93. The assembly block 91 is positioned in the assembly holes 8. The slot 92 initially limits the claw. The ball screw 94 fastens the claw in the slot 92 through elastic force, thus achieving the purpose of quick installation, pre-positioning and stable fixing of the claw.
[0031] A positioning locking element 6 for positioning the base 4 is installed on one side of the inclined support assembly. The positioning locking element 6 includes a side block on one side of the base 2, and a pin that can be elastically extended and retracted is installed on the side block. One end of the pin forms a locking engagement with the outer wall of the upper pressure plate 7. When it is necessary to lock the position of the upper pressure plate 7, the pin extends and abuts against the outer wall of the upper pressure plate 7 to restrict its rotation. When it is necessary to rotate, the pin retracts to release the lock, thus achieving the purpose of reliably locking the rotational position of the upper pressure plate 7.
[0032] In an embodiment of this utility model, a rotary drive assembly 5 for driving the upper pressure plate 7 and the base 4 to rotate is installed on one side of the top of the base 2. The rotary drive assembly 5 includes a servo motor 51 installed on the base 2. A drive gear 52 is fixed on the output shaft of the servo motor 51. A gear ring 53 that meshes with the drive gear 52 is installed on the outer side of the upper pressure plate 7. The rotation of the servo motor 51 drives the drive gear 52 to rotate. The drive gear 52 drives the upper pressure plate 7 and the base 4 to rotate through meshing with the gear ring 53, thereby achieving the purpose of precisely controlling the rotation angle of the upper pressure plate 7 and the base 4.
[0033] The working principle of the spherical metal part claw welding mechanism provided by this utility model is as follows: An inclined support assembly provides an inclined installation base; the inclined pad 1 creates an inclined angle for the entire installation structure; the base 2 and support plate 3 ensure structural stability; the guide post 10 ensures the coaxiality of the base 4 during rotation; the slot on the base 4 allows for the initial placement of the spherical metal part; the positioning pin 11, in conjunction with the positioning hole, restricts the relative movement and rotation between the base 4 and the upper pressure plate 7; the base 4 and the upper pressure plate 7 precisely position the spherical metal part; the slot 92 initially limits the claw; the ball screw 94, through elastic force, secures the claw in the slot 92; then, the assembly block 91 is placed into the assembly hole 8 to achieve the pre-positioning of the claw; the positioning locking member 6 can lock the rotational position of the base 4. When the upper pressure plate 7 needs to be locked in position, the pin extends and abuts against the outer wall of the upper pressure plate 7 to restrict its rotation. Then, the inclined support assembly makes the spherical metal part tilted to meet the requirement that laser welding must be perpendicular to the welding surface. After that, the vertical laser beam is used to weld the claw located in the mounting hole 8 at the lowest end of the upper pressure plate 7. After the welding is completed, the pin retracts to release the rotation restriction on the upper pressure plate 7. The servo motor 51 rotates to drive the drive gear 52 to rotate. The drive gear 52 drives the upper pressure plate 7 and the base 4 to rotate through the meshing transmission with the gear ring 53. After the claw of the spherical metal part is rotated to the welding position, the pin extends and abuts against the outer wall of the upper pressure plate 7 to restrict its rotation again before the welding work is carried out. This achieves the purpose of precise pre-positioning of the spherical metal part and the claw and rapid sequential welding.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
