[0026] Referring to Figure 1 - Figure 2 , according to an embodiment of a torsion bar correction device of the present utility model, it includes a machine table 11. A pneumatic chuck 12 is installed on the tabletop of the machine table 11, and a power source for driving the chuck 12 to rotate is arranged inside the machine table 11. That is, the chuck 12 can clamp and lock the torsion bar to be corrected. After the locking is completed, the power source can drive the torsion bar to rotate by driving the chuck 12, so as to facilitate its correction. The rotatable chuck 12 is a prior art, and its specific internal structure and rotation principle will not be described in detail here.

[0027] In addition, a corrector 13 is also installed on the machine table 11. The corrector 13 includes a plate body 21 and two rollers 22. An installation groove opening forward is provided in the plate body 21, and notches 23 are also provided through the upper and lower side surfaces of the installation groove. The two rollers 22 are rotatably connected in the installation groove and are symmetrically distributed left and right with respect to the notch 23. A positioning mechanism for controlling the position of the corrector 13 is also included. After the torsion bar is clamped in the chuck 12, it will rotate. Then, the corrector 13 moves forward, and the two rollers 22 approach and abut against the torsion bar, and the torsion bar is corrected (the torsion bar includes a rod body and a tooth seat. The tooth seat is clamped by the chuck 12, and the rod body is corrected relative to the tooth seat).

[0028] In addition, in the second embodiment of the corrector 13, a radial runout detector 14 is also provided on the corrector 13. The installation method of the radial runout detector 14 is that a locking plate 31 is fixed on the plate body 21, a cylinder 32 is provided on the locking plate 31, a slide plate 33 is installed on the piston rod in the cylinder 32, the radial runout detector 14 is fixed on the slide plate 33, the detection needle in the radial runout detector 14 is at the same height as the roller 22, and the detection needle is located on the front side of the roller 22.

[0029] In the second embodiment of the corrector 13, after the corrector 13 is corrected and reset backward, the cylinder 32 controls the slide plate 33 and the radial runout detector 14 to move to the right, and the detection needle in the radial runout detector 14 is attached to the torsion bar clamped by the chuck 12 and its runout is detected. If the indicating light set on the machine table 11 lights green, it indicates that the corrected torsion bar meets the standard, and the cylinder 32 can control the slide plate 33 and the radial runout detector 14 to reset to the left, and then the chuck 12 is unlocked, and the staff can take out the torsion bar that has been corrected and subjected to runout detection.

[0030] In this embodiment, a frame is provided on the machine table 11. The positioning mechanism includes a fixing plate 41 provided on the frame. A first motor 42 is fixed on the fixing plate 41. A first output shaft in the first motor 42 is connected to a first threaded shaft 43 through a coupling. A middle plate 44 threadedly connected to the first threaded shaft 43 is slidably connected back and forth on the frame. The front side of the middle plate 44 is connected to a mounting plate 45 through a connecting rod, and the corrector 13 is installed on the mounting plate 45. When the first motor 42 is powered on, it can drive the middle plate 44, the mounting plate 45 and the corrector 13 to move back and forth through the first threaded shaft 43. When the above components move forward, the rollers 22 in the corrector 13 can abut against the clamped torsion bar and correct it.

[0031] In order to enable the torsion bar correction device to correct torsion bars of different heights, a slide rail is provided on the front side of the mounting plate 45, and the corrector 13 is mounted on the slide rail. The mounting plate 45 is also provided with a cross plate, and a handwheel 46 is mounted on the cross plate. The handwheel 46 is connected to a No. 2 threaded shaft 47, and the No. 2 threaded shaft 47 is vertically arranged and threadedly connected to the plate body 21 in the corrector 13. The staff can control the upper and lower positions of the corrector 13 by turning the handwheel 46. The roller 22 in the corrector 13 needs to be against the upper edge of the torsion bar curved surface to achieve a better correction effect.

[0032] In the third embodiment of the corrector 13, a positioning plate 24 is further provided on the corrector 13, and a positioning hole 25 is provided in the positioning plate 24. The lower edge of the positioning hole 25 is chamfered so that the torsion bar can enter the positioning hole 25 when the corrector 13 moves downward to perform secondary correction.

[0033] Torsion bar correction process: First, the staff inserts the torsion bar into the chuck 12 and clamps and rotates it, then the corrector 13 moves forward and corrects the rotating torsion bar through the roller 22, and at this time the positioning plate 24 is located above the torsion bar;

[0034] After the corrector 13 moves forward to its position, the corrector 13 moves downward, at which time the torsion bar can be inserted into the positioning hole 25 and a secondary correction is performed.

[0035] After the calibration is completed, the corrector 13 resets upward and moves backward, and then the radial runout detector 14 moves to the right and makes the detection inside it detect the rotating torsion bar. After the detection is completed, the radial runout detector 14 resets to the left, and the chuck 12 stops and unlocks, and the calibration and detection of the torsion bar are completed.
