The prior art corrects the clamping posture of the workpiece by setting a correction structure for correcting an inner conical groove and moving it back and forth along the slide rail. The inner conical surface of the correction shaft contacts the spherical surface of the workpiece clamped by the clamping chuck to meet the precision requirements and ensure the processing effect.

[0003] In actual use of the prior art, the correction structure can only achieve correction by abutting the end of the workpiece. In order to ensure the correction effect, the correction structure is generally left at the end of the workpiece to maintain continuous correction. However, if the end of the workpiece needs to be processed, the correction structure will cause interference and must be removed for construction. After the correction structure is removed, the workpiece loses the limit of the correction structure and the deviation problem is likely to reappear. Therefore, it is not flexible and convenient to use.

[0004] To this end, the present application provides a correction device to solve the above-mentioned technical problems. Utility Model Content

[0025] In the specific implementation, in this embodiment, a lug is fixed to one end of the upper end surface of the base 1 away from the pneumatic chuck 2, and the drive screw 5 is rotatably installed between the bottom of the pneumatic chuck 2 and the lug, and the motor 6 is fixed on the lug.

[0026] like Figure 2 , Figure 3 and Figure 4 As shown, the interior of the correction cylinder 7 is hollow and allows the workpiece 9 to pass horizontally. A plurality of sliding grooves 701 are opened on the inner wall of the correction cylinder 7. A correction rod 702 for abutting the workpiece 9 is hingedly installed at one end of the sliding groove 701. In specific implementation, at least three correction rods 702 are provided in the correction cylinder 7 and are symmetrically distributed in the correction cylinder 7. The center of the correction cylinder 7 is horizontally flush with the center position of the pneumatic chuck 2. In the present embodiment, four correction rods 702 are provided and are symmetrically distributed on the inner wall of the correction cylinder 7. When in use, the workpiece 9 passing through the correction cylinder 7 can be synchronously abutted and corrected from four aspects.

[0027] Cooperate Figure 3 and Figure 4As shown, a slider 705 is slidably installed in the sliding groove 701 at one end away from the correction rod 702, and a driving rod 706 for supporting the correction rod 702 is movably installed on the slider 705. Specifically, an installation groove 703 is opened at the end of the correction rod 702 away from the sliding groove 701, and a contact roller 704 is rotatably installed in the installation groove 703. The contact roller 704 is exposed from the end of the sliding groove 701 and can be used to abut the surface of the workpiece 9 to avoid scratching the workpiece 9, which is beneficial to ensuring the safety of the workpiece 9. At the same time, in this embodiment, one end of the driving rod 706 is rotatably installed on the slider 705, and the other end is rotatably installed in the installation groove 703, so that the driving rod 706 can support the correction rod 702 at different positions to adjust the degree of the correction rod 702 toward the center position of the correction cylinder 7, so that the correction rod 702 can abut against workpieces 9 of different specifications.

[0028] At the same time, a connecting rod 707 is fixed to the end of the slider 705 away from the correction rod 702, and the connecting rod 707 extends out of the end of the correction cylinder 7, and the end of the correction cylinder 7 is threadedly sleeved with an adjusting cylinder 8, and an abutment ring 801 is fixed around the inner wall of the end of the adjusting cylinder 8 away from the correction cylinder 7, and a magnetic ring 802 is installed around the abutment ring 801, and the magnetic ring 802 is magnetically fixed to the connecting rod 707.

[0030] In addition, through the cooperation of the limiting slide groove 3, the support frame 4, the driving screw 5 and the motor 6, the driving screw 5 can be driven to rotate by starting the motor 6, and then the support frame 4 can be controlled to move the correction cylinder 7, so that the position of the correction cylinder 7 on the workpiece 9 can be adjusted, so that the correction effect can be maintained at different positions on the workpiece 9. Compared with the prior art that can only correct at the end of the workpiece 9, this device is more flexible and convenient to use, and can also avoid obstruction of the processing position of the workpiece 9.

[0031] At the same time, when the workpiece 9 is subjected to limit correction, the adjusting cylinder 8 threadedly installed on the surface of the rotating correction cylinder 7 can be moved relative to the correction cylinder 7, so that when the adjusting cylinder 8 moves, the abutment ring 801 can be used to abut the connecting rod 707 to drive the slider 705 to slide in the sliding groove 701, and since the connecting rod 707 is magnetically fixed to the magnetic ring 802 on the abutment ring 801, the slider 705 and the driving rod 706 can be conveniently controlled to change the inclination angle of the correction rod 702, so that multiple correction rods 702 can abut against workpieces 9 of various diameters together, with strong versatility and good use effect.
