[0001] The utility model relates to the technical field of screw rod processing equipment, in particular to an automatic guide device for screw rod processing. Background Art

[0002] Ball screws are ideal products for converting rotary motion into linear motion, or vice versa. They are the most commonly used transmission components in tool machinery and precision machinery. Their main function is to convert rotary motion into linear motion, or torque into axial repetitive force. They also feature high precision, reversibility, and high efficiency. Due to their low friction resistance, ball screws are widely used in various industrial equipment and precision instruments.

[0022] like Figure 1-5As shown, in this embodiment: an automatic guide device for screw processing includes a base 2, a socket 8 is opened on the surface of the base 2, a rotating shaft 9 is inserted into the inside of the socket 8, and a driving force is applied to the gear 12 by means of the rotating shaft 9. The rotating shaft 9 is distributed in an upper and lower part, and a card groove 10 is opened on the surface of the rotating shaft 9 located at the upper part, and a slide groove 11 is opened on the surface of the rotating shaft 9 located at the lower part. By setting the rotating shaft 9 as a socket assembly, it is convenient to lock the rotating shaft 9 and facilitate driving the gear. The surface of the card groove 10 is internally connected with a card groove The fixture 15 is engaged with the inside of the slot 10 to limit the position of the rotating shaft 9. The end of the rotating shaft 9 is fixedly connected to the gear 12. The surface of the gear 12 is engaged with the rack 13. With the help of the engagement of the gear 12 and the rack 13, the clamping shaft 16 is driven to fix the end of the screw blank. The interior of the rack 13 is plugged with the mounting shaft 14, and the end of the mounting shaft 14 is fixedly connected with the clamping shaft 16. With the help of the clamping shaft 16, the screw blank is fixed, so that the base 2 can drive the screw blank to move on the surface of the bracket 1.

[0023] Furthermore, a sleeve 3 is fixedly connected to the outer surface of the base 2, and a bracket 1 is sleeved inside the sleeve 3. A threaded hole 4 is opened on the surface of the sleeve 3, and a bolt 5 is inserted into the internal thread of the threaded hole 4. The end of the bolt 5 is fixedly connected to a bearing 6, and a fastening shaft 7 is fixedly connected to the surface of the bearing 6. The fastening shaft 7 is used to fix the base 2 on the surface of the bracket 1, so that the base 2 can drive the screw blank to move on the surface of the bracket 1.

[0024] Furthermore, the surface of the bearing 6 is fixedly connected to the inside of the upper surface of the fastening shaft 7, and the inner wall of the bearing 6 is fixedly connected to the end surface of the bolt 5. The bearing 6 is used to connect the bolt 5 and the fastening shaft 7, so that the fastening shaft 7 can be driven by the bolt 5 to adjust the height of the surface of the bracket 1.

[0025] Furthermore, each rack 13 and mounting shaft 14 form a group together, and each group of racks 13 and mounting shafts 14 are respectively installed on the front and rear sides of the top inner wall of the clamping shaft 16. Through the oppositely opened racks 13 and mounting shafts 14, it is convenient for the staff to manually fix the end of the screw blank.

[0026] Furthermore, the slot 10 and the slide 11 are staggered in the upper and lower parts of the rotating shaft 9, and the inner wall surface of the upper part of the rotating shaft 9 is slidably connected to the inside of the slide 11. With the help of the slot 10 and the slide 11, the rotating shaft 9 is flexibly driven to rise and fall and limit, so that the staff can manually stabilize the screw blank and the base 2.

[0027] Furthermore, the top end of the clamp 15 extends into the interior of the slot 10, and the end of the clamp 15 is fixedly connected to the inner wall surface of the base 2. The spring of the clamp 15 drives the clamp 15 to be confined inside the slot 10, thereby facilitating the stabilization of the rotating shaft 9 and limiting the rotation of the gear 12.

[0028] Furthermore, the bolts 5 and the rotating shaft 9 both extend upward on the surface of the base 2 and the sleeve 3, and are distributed in a triangular shape between the base 2 and the sleeve 3. The bolts 5 and the rotating shaft 9 respectively limit the fixing effect of the base 2 on the screw rod and the fixing effect on the bracket 1, thereby flexibly moving the position of the screw rod blank.

[0029] The method of using this embodiment is: When using, please refer to Figure 1-5 First, the staff needs to manually insert the end of the screw blank into the interior of the base 2, and then manually lift the shaft 9 upward and rotate it. The upper half of the shaft 9 moves upward on the surface of the lower half, so that the slot 10 disengages the fixture 15. At the same time, the engagement of the slide groove 11 drives the gear 12 to rotate, and the further engagement of the rack 13 drives the clamping shafts 16 on both sides to move, and then fix the end of the screw blank. After the fixation is completed, press the upper half of the shaft 9 back down again, and then slide the base 2 on the surface of the bracket 1 according to different needs. When the base 2 slides to the required position, manually rotate the bolt 5 inside the threaded hole 4. With the engagement of the bolt 5 and the threaded hole 4, drive the fastening shaft 7 to move down inside the sleeve 3, thereby fixing the base 2 to the surface of the bracket 1.
