[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-4 A shaft ball sleeve processing fixture includes a base 1, an adjustment mechanism 2, a driving mechanism 3 and an internal support mechanism 4.

[0029] The four corners of the bottom surface of the base 1 are fixedly connected with support columns 5, and the bottom surface of each support column 5 is installed with a positioning seat.

[0030] By providing the support column 5 and the positioning seat, the device can be conveniently installed on a contact surface such as a machine tool or a workbench, so as to facilitate the stable internal support positioning of the shaft ball hole sleeve.

[0031] The adjustment mechanism 2 includes a rotating rod 201 rotatably sleeved on the inner wall of the base 1 and a flat gear 202 fixedly connected to the top of the rotating rod 201 . When the rotating rod 201 rotates, the flat gear 202 is driven to rotate.

[0032] And a guide rail 203 fixedly connected to the inner wall of the base 1 , and two movable connecting plates 204 are installed on the outer surface of the guide rail 203 .

[0033] A rack 205 is fixedly connected to the outer surface of each connecting plate 204 . The two racks 205 are meshed with the plane gear 202 . A positioning plate 206 is fixedly connected to the upper surface of each rack 205 .

[0034] When the planar gear 202 rotates, the two connecting plates 204 are driven to move toward or away from each other along the guide rail 203 through the two racks 205 , thereby enabling the two positioning plates 206 to move toward or away from each other.

[0035] In this way, the positions of the two positioning plates 206 can be adjusted according to the length of the shaft ball hole sleeve, thereby facilitating the positioning of shaft ball hole sleeves of different models and meeting various usage requirements.

[0036] The driving mechanism 3 includes a worm wheel 301 fixedly connected to the bottom end of the rotating rod 201, a servo motor 303 and a rotatable worm 302 are installed on the bottom surface of the base 1, the output shaft of the servo motor 303 is fixedly connected to the shaft end of the worm 302, and the worm 302 is meshed with the worm wheel 301.

[0037] The servo motor 303 can be started to drive the worm 302 to rotate. When the worm 302 rotates, the rotating rod 201 can be driven to rotate through the worm wheel 301. When the rotating rod 201 rotates, the flat gear 202 can be driven to rotate.

[0038] By combining the worm 302 and the worm wheel 301 together, the rotation of the rotating rod 201 and the plane gear 202 can be limited. When the worm 302 drives the worm wheel 301 to rotate, it can achieve the effect of deceleration and self-locking. In this way, the worm 302 can drive the worm wheel 301 to rotate, while the worm 302 cannot drive the worm wheel 301 to rotate in the opposite direction. Therefore, the rotation of the rotating rod 201 can only be achieved by the rotation of the worm 302, thereby facilitating the limitation of the positions of the two positioning plates 206 and preventing the positioning plates 206 from moving at will.

[0039] The inner support mechanism 4 includes a bidirectional screw rod 401 rotatably sleeved on the inner walls of the two positioning plates 206 . The outer surfaces of the two bidirectional screw rods 401 are threadedly connected to two sliders 402 . The outer surface of each slider 402 is fixedly connected to a positioning rod 403 .

[0040] Two limit rods 404 are fixedly connected to the inner wall of each positioning plate 206 , and the two sides of the four sliders 402 are slidably mounted on the outer surfaces of the four limit rods 404 . The limit rods 404 can make the sliders 402 more stable during movement.

[0041] When the bidirectional screw rod 401 rotates, the corresponding two sliders 402 can move toward or away from each other along the corresponding two limit rods 404, thereby enabling the two positioning rods 403 to move toward or away from each other.

[0042] In this way, the inner diameter of the shaft ball sleeve can be adjusted so that the two ends of the shaft ball sleeve can be supported and positioned by the two corresponding positioning rods 403, so that the shaft ball sleeve can be suspended and positioned above the base 1.

[0043] This can effectively reduce the contact area between the device and the outer surface of the shaft ball hole sleeve, facilitate grinding and other processing on the outer surface of the shaft ball hole sleeve, solve the problems mentioned in the comparative documents in the background technology, and facilitate use.

[0044] The outer surface of each limiting rod 404 is fixedly connected to a limiting sleeve 405, the diameter of which is greater than the diameter of the limiting rod 404. By setting the limiting sleeve 405, the moving trajectory of the slider 402 can be limited, thereby facilitating the internal support positioning of different types of shaft ball hole sleeves.

[0045] The shaft end of each bidirectional screw rod 401 is fixedly connected to a handle 406 , and the outer surface of each handle 406 is coated with an anti-slip layer. By providing the handle 406 , the contact area of ​​the bidirectional screw rod 401 can be increased, making it easier to rotate the bidirectional screw rod 401 .

[0046] A protective plate 6 is provided on the outside of the base 1, and mounting bolts 7 are installed at the four corners of the protective plate 6. The protective plate 6 is installed on the upper surface of the base 1 by means of the four mounting bolts 7. By providing the protective plate 6 and the mounting bolts 7, the debris generated during the internal processing of the base 1 can be cleaned regularly, thereby improving the practicality of the device.

[0047] The bottom ends of the two positioning plates 206 are respectively slidably mounted in the reserved grooves on the surface of the protective plate 6 , in which auxiliary rods 8 are installed, and the bottom ends of the two positioning plates 206 are respectively slidably mounted on the outer surfaces of the four auxiliary rods 8 .

[0048] The auxiliary rod 8 can make the two positioning plates 206 more stable during the movement, making it easier to position different shaft ball hole sleeves.

[0049] When the two-way screw rod 401 is rotated, the two corresponding sliders 402 will move closer to or away from each other along the two corresponding limit rods 404. In this way, one end of the shaft ball hole sleeve can be sleeved on the outside of the two positioning rods 403, and then the two-way screw rod 401 is rotated in the opposite direction to make the two positioning rods 403 move away from each other, thereby realizing the work of positioning the inner support of one end of the shaft ball hole sleeve by the two positioning rods 403, and then the servo motor 303 is driven to make the two positioning plates 206 move closer to each other, and make the other end of the shaft ball hole sleeve be sleeved on the outside of the positioning rod 403 on the other side. When the servo motor 303 is started, the worm 302 will be driven to rotate, and the rotation of the worm 302 will drive the worm wheel 301, The rotating rod 201 and the plane gear 202 rotate. When the plane gear 202 rotates, the two connecting plates 204 will move closer to each other along the guide rail 203 through the two racks 205, so that the two positioning plates 206 can move closer to each other, so that the other end of the shaft ball hole sleeve can be sleeved on the outside of the positioning rod 403 on the other side, and then the servo motor 303 is stopped, and the two-way screw rod 401 on the other side is rotated, so that the two positioning rods 403 on the other side can move away from each other at the other end of the shaft ball hole sleeve, thereby realizing the work of internal support of the other end, so that the shaft ball hole sleeve can be suspended and positioned above the base 1, which can effectively reduce the contact area between the device and the outer surface of the shaft ball hole sleeve, making it convenient for the staff to perform grinding and other processing on the outer surface of the shaft ball hole sleeve, and the device can meet the processing work of various types of shaft ball hole sleeves by adjusting the positions of the positioning plate 206 and the positioning rod 403, which is more practical.
