DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] The terms "upper", "lower", "left", "right", "middle" and "one" used in the present invention are only for the convenience of description and are not intended to limit the scope of application of the present invention. Changes or adjustments to their relative relationships shall be deemed to be within the scope of application of the present invention without substantially changing the technical content.

[0025] Reference Figures 1-6 A fixture for processing large ball pin holes includes an operating table 1, a mounting block 2 is fixedly installed on the upper surface of the operating table 1, a circular positioning opening 3 is opened on the surface of the mounting block 2, a plurality of rectangular openings 4 are opened in a circular shape on the surface of the mounting block 2, a sliding rod 5 is fixedly installed in the rectangular opening 4, a U-shaped positioning rod 6 is slidably sleeved on the sliding rod 5, and a processing opening 7 connected to the positioning opening 3 is opened on the upper surface of the mounting block 2.

[0026] A threaded rod 8 is installed horizontally on the side wall of the operating table 1. An adjusting wheel is fixedly installed on the end of the threaded rod 8 away from the operating table 1. The surface of the adjusting wheel is provided with anti-slip grooves. A slide plate 9 is threadedly sleeved on the threaded rod 8. A ring 10 is fixedly installed on the top of the slide plate 9. A plurality of connecting rods 11 are fixedly installed on the surface of the ring 10 in a circular shape. An I-shaped block 12 is fixedly installed on the end of the connecting rod 11. An inclined rod 13 is fixedly installed on the surface of the positioning rod 6. An inclined opening 14 is opened on the surface of the inclined rod 13. Multiple I-shaped blocks 12 are respectively slidably arranged in the multiple inclined openings 14.

[0027] First, pass the ball pin to be processed through the positioning port 3, and control the ball pin to move horizontally until it moves to the specified position of the opening corresponding to the position of the processing port 7. At this time, by rotating the threaded rod 8, control the slide plate 9 to move the ring 10 and multiple I-blocks 12 horizontally. Multiple I-blocks 12 will slide in multiple oblique openings 14 respectively. Under the action of the inclined surface pressure, when the I-block 12 moves in the direction close to the mounting block 2, multiple positioning rods 6 will move away from each other, and when the I-block 12 moves in the direction away from the mounting block 2, multiple positioning rods 6 will move closer to each other until multiple positioning rods 6 are tightly against the surface of the ball pin located in the positioning port 3. The clamping and positioning work of the ball pin can be completed, and the positioning and clamping work of ball pins of different sizes can be completed quickly, which is convenient and fast, and improves the practicality of the device and the work efficiency of ball pin drilling.

[0028] A pair of L-shaped connecting rods 15 are fixedly installed on the surface of the ring 10 and the upper surface of the operating table 1. A threaded barrel 16 is fixedly installed between the ends of each pair of connecting rods 15. The two threaded barrels 16 are provided with fixing components for clamping the two ends of the ball pin. The fixing components include two fixing bolts 17. The two fixing bolts 17 are respectively threadedly installed in the two threaded barrels 16. The two fixing bolts 17 are located on the same horizontal line and are both located on the same axis as the positioning port 3.

[0029] When the ball pin is moved to a suitable position and is clamped and fixed by multiple positioning rods 6, the two fixing bolts 17 are rotated. When the fixing bolts 17 are rotated, they will move laterally in the threaded tube 16, and the ends of the two fixing bolts 17 that are close to each other are controlled to tightly abut against the two ends of the ball pin, respectively, so that the ball pin is positioned and clamped between the two fixing bolts 17, which can improve the stability of the clamped ball pin.

[0030] An anti-slip layer is bonded to the surfaces of the positioning rod 6 at the ends of the two fixing bolts 17 that are close to each other. The material of the anti-slip layer is rubber.

[0031] The anti-slip layer made of rubber has good elasticity and viscosity, which can increase the friction between the fixing bolt 17 and the positioning rod 6 and the contact surface of the ball pin, and can also avoid wear on the surface of the ball pin due to pressure and clamping.

[0032] In the present invention, the ball pin to be processed is first passed through the positioning opening 3, and the ball pin is controlled to move horizontally until it moves to the specified position of the opening corresponding to the position of the processing opening 7. At this time, the slide 9 is controlled to move the ring 10 and multiple I-blocks 12 horizontally by rotating the threaded rod 8. Multiple I-blocks 12 will slide in multiple oblique openings 14 respectively. Under the action of the inclined surface pressure, when the I-block 12 moves in the direction close to the mounting block 2, the multiple positioning rods 6 will move away from each other, and when the I-block 12 moves in the direction away from the mounting block 2, the multiple positioning rods 6 will move closer to each other until the multiple positioning rods 6 are tightly against the surface of the ball pin located in the positioning opening 3. The clamping and positioning work of the ball pin can be completed, and the positioning and clamping work of ball pins of different sizes can be completed quickly, which is convenient and fast, and improves the practicality of the device and the work efficiency of ball pin drilling.

[0033] In the present invention, unless otherwise clearly specified or limited, the terms “installed”, “connected”, “connected”, “fixed” and the like should be understood in a broad sense.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
