Detailed Embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1 to 3 , the present utility model provides a technical solution:

[0025] A machining fixture for a deflector includes a support base 1. An axial positioning device for axially supporting the deflector 2 is sequentially installed above the support base 1; an ear plate top pressing device for top pressing the side plates on both sides of the deflector 2; a central positioning device for positioning the deflector 2; and a plurality of compression bolts 3 for fixing the deflector 2.

[0026] When it is fixed, the deflecting body 2 is axially supported by an axial positioning device, ensuring the dimensional requirements of the overall hole position height level of the deflecting body 2. The side plates on both sides of the deflecting body 2 are tightened by an ear plate tightening device to reduce the vibration of the workpiece. The deflecting body 2 is positioned by a center positioning device to ensure the left-right symmetry of the entire deflecting body 2. Then, the deflecting body 2 is fixed by a pressing bolt 3.

[0027] Symmetrically mounted above the support base 1 are also a bottom support column 4 and an inclined side support column 5 for pressing against the bottom and the inclined side of the deflecting body 2.

[0028] A fixed side plate 6 and a number of tightening plates 7 are mounted above the support base 1 for pressing against the side of the deflecting body 2.

[0029] When fixing, first the workpiece is pressed tightly by the bottom support column 4 and the inclined side support column 5 to ensure that the workpiece cannot move around. Then manually, the deflecting body 2 is pressed tightly by passing a fixing bolt through the fixed side plate 6 and the tightening plate 7.

[0030] The axial positioning device includes a support frame 8 fixed above the support base 1 and a positioning sleeve 9 mounted above the support frame 8, achieving the purpose of axial positioning and support, making the workpiece clamping more efficient, the stress points more evenly distributed, reducing the pressing deformation amount, the position of the workpiece more accurate, and effectively reducing the adjustment range.

[0031] The ear plate tightening device is a U-shaped baffle 10 mounted above the support base 1. The U-shaped baffle 10 cooperates with the fixed side plate 6 and the tightening plate 7, making the clamping more convenient, effectively reducing the vibration of the workpiece, significantly improving the processing efficiency, and making it more time-saving and labor-saving for the machining personnel to calibrate.

[0032] The center positioning device includes a positioning plate 11 mounted above the support base 1 and a core rod 12 penetrating and sleeved above the positioning plate 11. When fixing, both ends of the core rod 12 pass through the shaft holes of the deflecting body 2 to achieve the purpose of calibration and positioning.
