Description

Technical Field

[0001] This utility model relates to the field of ball head machining, and in particular to a multi-angle synchronous clamping fixture for ball head machining. Background Technology

[0002] Ball-head workpieces are widely used in mechanical manufacturing (such as automotive steering systems). Their surface processing requires high-precision clamping to ensure forming quality. Traditional clamping methods often rely on manual adjustment of multiple clamping points, resulting in uneven clamping force, cumbersome operation, and long processing time. They are difficult to adapt to ball heads of different sizes and are prone to workpiece deformation or processing errors. Existing equipment also lacks an effective synchronous drive structure, affecting stability and automation. Optimization of the design is urgently needed to improve efficiency.

[0003] Therefore, in order to address the above problems, a multi-angle synchronous clamping fixture for ball head machining is now being developed. Utility Model Content

[0004] To overcome the shortcomings of traditional clamping methods, which often rely on manual adjustment of multiple clamping points, resulting in uneven clamping force, cumbersome operation, long time consumption, difficulty in adapting to ball heads of different sizes, and easy to cause workpiece deformation or processing errors, and the lack of effective synchronous drive structure in existing equipment, which affects stability and automation level, and urgently requires optimized design to improve efficiency, this utility model provides a multi-angle synchronous clamping fixture for ball head processing.

[0005] The technical implementation scheme of this utility model is as follows:

[0006] A multi-angle synchronous clamping fixture for ball head machining includes a mounting frame, a support seat slidably connected to the mounting frame, a ball head placed on the support seat, a drive motor located on the upper right side of the mounting frame, a bidirectional lead screw connected to the output shaft of the drive motor, the bidirectional lead screw being rotatably connected to the mounting frame, two symmetrical clamping members threadedly connected to the bidirectional lead screw, a worm gear located in the middle of the bidirectional lead screw, a threaded rod rotatably connected to the upper part of the mounting frame, a worm wheel mounted at the bottom of the threaded rod, the worm wheel meshing with the worm gear, and another clamping member threadedly connected to the threaded rod.

[0007] Furthermore, the support base is provided with a concave structure.

[0008] Furthermore, the clamping member is in contact with the mounting bracket.

[0009] Furthermore, all three clamping components have anti-slip textures on their inner sides.

[0010] Furthermore, the inner sides of the clamping components are all arc-shaped structures.

[0011] Furthermore, a drive assembly is provided at the lower part of the mounting bracket, and a driven gear is connected to the output shaft of the drive assembly. The driven gear is rotatably connected to the mounting bracket, and a rack is provided on the rear side of the support base, which meshes with the driven gear.

[0012] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0013] This invention ensures that the ball head is firmly and evenly clamped through synchronous clamping in three directions, effectively preventing displacement and improving processing accuracy. It is easy to operate and is automated by motor drive, which enhances production efficiency. The adjustable design can adapt to workpieces of different sizes, enhancing versatility.

[0019] The present invention will now be described in detail with reference to the accompanying drawings.

[0020] A multi-angle synchronous clamping fixture for ball head machining, such as Figures 1-4As shown, the device includes a mounting frame 1, a support base 2 slidably connected to the mounting frame 1, a concave structure on the support base 2, and a ball head 3 placed on the support base 2. A drive motor 5 is located on the upper right side of the mounting frame 1, and a bidirectional lead screw 6 is connected to the output shaft of the drive motor 5. The bidirectional lead screw 6 is rotatably connected to the mounting frame 1. Two symmetrical clamping parts 4 are threadedly connected to the bidirectional lead screw 6, and the clamping parts 4 are in contact with the mounting frame 1. A worm gear 7 is located in the middle of the bidirectional lead screw 6. The mounting frame 1... The mounting bracket 1 is rotatably connected to a threaded rod 9, and a worm gear 8 is installed at the bottom of the threaded rod 9. The worm gear 8 meshes with the worm 7. Another clamping member 4 is threadedly connected to the threaded rod 9. All three clamping members 4 have anti-slip textures on their inner sides and are all arc-shaped structures. A drive assembly 10 is provided at the lower part of the mounting bracket 1. A driven gear 11 is connected to the output shaft of the drive assembly 10. The driven gear 11 is rotatably connected to the mounting bracket 1. A rack 12 is provided at the rear side of the support base 2. The rack 12 meshes with the driven gear 11.

[0021] It should be noted that when the drive motor 5 is started, it drives the bidirectional lead screw 6 on its output shaft to rotate. Since the bidirectional lead screw 6 is rotatably connected to the mounting bracket 1, its two sections of threads with opposite directions will drive the two symmetrical clamping parts 4 threadedly connected to it to move horizontally inward (i.e., move closer to each other) along the guide of the mounting bracket 1. At the same time, the worm 7 installed in the middle of the bidirectional lead screw 6 rotates accordingly. The worm 7 meshes with the worm wheel 8 rotatably installed on the upper part of the mounting bracket 1, driving the worm wheel 8 to rotate. The worm wheel 8 drives the threaded rod 9 installed coaxially with it to rotate. The threaded rod 9 is connected to another... One clamping element 4 (located above) moves vertically (downward) under the action of the thread. Through the speed reduction and torque increase characteristics of the worm gear 8 and worm 7, clamping in this direction can provide a greater clamping force. The movement of the three clamping elements 4 (left, right and upper angle directions) is coordinated. Since their inner sides are all set with arc surface structure and anti-slip texture, they can simultaneously and evenly abut against the outer surface of the ball head 3 workpiece placed in the concave structure of the support seat 2 from three different angles, realizing multi-angle synchronous and stable self-centering clamping, firmly wrapping the ball head 3, and effectively preventing it from displacing or rotating during processing.

[0022] On the other hand, to accommodate different sizes or adjust the positioning, the drive assembly 10 operates, driving the driven gear 11 on its output shaft to rotate. The driven gear 11 meshes with the rack 12 on the rear side of the support base 2, causing the support base 2 to slide smoothly horizontally on the mounting frame 1, thereby adjusting the position of the ball head 3 workpiece relative to the clamping area. The entire device controls the linkage of the clamping mechanism and the feed positioning of the workpiece through the drive motor 5 and the drive assembly 10 respectively, ensuring accurate positioning and stable clamping of the ball head 3 during the machining process. The combination of the motion adjustment of the drive assembly 10 and the synchronous action of the clamping mechanism jointly ensures that the ball head 3 workpiece is safely and reliably fixed during multi-angle machining, providing a basic guarantee for subsequent precision machining operations.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
