[0024] This adjustable universal auxiliary fixture for EPS electric steering column includes a base plate 1, a transverse guide rail 2, a transverse lead screw 5, a transverse clamp 3, a longitudinal support seat, and a longitudinal clamp 9 (see instruction manual appendix). Figure 1 ).
[0025] A transverse clamp 3 is slidably mounted on the base plate 1 via a transverse guide rail 2; a transverse lead screw 5 is mounted on the base plate 1 between the transverse guide rails 2 via a bearing seat and a support plate 4; the transverse lead screw 5 is connected to the transverse clamp 3; a control handwheel 29 is installed at one end of the transverse lead screw 5.
[0026] The operation can be controlled by rotating the handwheel 29 to rotate the horizontal lead screw 5, which controls the horizontal clamp 3 to slide back and forth along the horizontal guide rail 2.
[0027] The horizontal clamp 3 has horizontal pointers 11 mounted on both sides; the horizontal guide rail 2 inside the horizontal pointers 11 has a horizontal scale 12 mounted on it (see instruction manual appendix). Figure 2 and 3The purpose of setting the horizontal pointer 11 and the horizontal scale 12 is to indicate the horizontal position of the horizontal clamp 3 with the help of the horizontal scale 12 during the operation of the horizontal clamp 3 sliding back and forth along the horizontal guide rail 2, so as to facilitate the operation of the operator.
[0028] The transverse clamp 3 includes a transverse sliding seat 15, a mounting base plate 16, a U-shaped upright plate 18, a standard pin 23, a tightening handle 20, a locking screw 19, and a threaded bushing 21. The transverse sliding seat 15 is slidably mounted on the transverse guide rail 2; the transverse sliding seat 15 is connected to the transverse lead screw 5 (see the attached instruction manual). Figure 1 and 2 ).
[0029] A mounting base 16 is mounted on the horizontal sliding seat 15; a U-shaped upright plate 18 is mounted on the mounting base 16 via a positioning assembly 17 (see the instruction manual). Figure 6 and 7 ).
[0030] The positioning component 17 includes a diamond-shaped pin 25, a clamping screw 26, and a snap-fit bushing 24; two sets of snap-fit bushings 24 are symmetrically installed at the lower end of the U-shaped upright plate 18; the diamond-shaped pin 25 is inserted into the snap-fit bushing 24; the lower end of the diamond-shaped pin 25 is inserted into the mounting base plate 16; the clamping screw 26 is threadedly connected to the mounting base plate 16 on one side of the diamond-shaped pin 25; one end of the clamping screw 26 is in contact with the snap-fit interface 27 on the diamond-shaped pin 25.
[0031] A locking screw 19 is movably mounted in the middle of the U-shaped upright plate 18 through a through hole; the upper end of the locking screw 19 extends to the upper end of the U-shaped upright plate 18 and is fixedly fitted with a tightening handle 20; a threaded bushing 21 is mounted on the mounting base plate 16 at the lower end of the locking screw 19; the locking screw 19 is connected to the threaded bushing 21. The purpose of this arrangement of the locking screw 19 and the positioning assembly 17 is to allow for quick replacement of different models of U-shaped upright plates 18 during operation.
[0032] Two sets of guide bushings 22 are symmetrically installed on the upper end of the U-shaped upright plate 18; standard pins 23 are inserted into the U-shaped upright plate 18 through the guide bushings 22.
[0033] A longitudinal support plate 7 is mounted on the base plate 1 at one end of the transverse guide rail 2 via multiple support blocks 6; two sets of longitudinal clamps 9 are slidably mounted on the longitudinal support plate 7 via longitudinal guide rails 8 (see instruction manual appendix). Figure 2 and 3 The longitudinal clamp 9 is equipped with a quick-release clamp 28 (see instruction manual appendix). Figure 1 and 5 During operation, the quick-clamp 28 can clamp and fix the workpiece 34 (see the instruction manual appendix). Figure 1 ).
[0034] A longitudinal lead screw 10 is mounted on the longitudinal support plate 7 between the longitudinal guide rails 8 via a bearing seat and a support plate 4; a control handwheel 29 is installed at one end of the longitudinal lead screw 10. The longitudinal lead screw 10 is connected to the longitudinal clamp 9. During operation, the longitudinal clamp 9 can be driven to move back and forth on the longitudinal guide rail 8 by rotating the longitudinal lead screw 10 through the control handwheel 29; when the longitudinal lead screw 10 rotates in the forward direction, the two sets of longitudinal clamps 9 move closer together; when the longitudinal lead screw 10 rotates in the reverse direction, the two sets of longitudinal clamps 9 separate; thus, the distance between the two sets of longitudinal clamps 9 can be adjusted by rotating the longitudinal lead screw 10 during operation.
[0035] The longitudinal clamp 9 has longitudinal pointers 13 mounted on both sides; the longitudinal guide rail 8 inside the longitudinal pointers 13 has a longitudinal scale 14 mounted on it (see instruction manual appendix). Figure 1 , 2 (and 3). During operation, the position of the longitudinal clamp 9 can be determined by the longitudinal pointer 13 and the longitudinal scale 14.
[0036] A locking device 30 is mounted on the support plate 4 on one side of the control handwheel 29; the locking device 30 includes a U-shaped clamp 31, a locking bolt 32, and a locking nut 33; the support plate 4 is equipped with a U-shaped clamp 31; the open end of the U-shaped clamp 31 is equipped with a locking bolt 32; the upper end of the locking bolt 32 is threaded with a locking nut 33 (see the appendix of the instruction manual). Figure 1 , 2 and 8).
[0037] The purpose of the locking device 30 is to ensure that after the longitudinal lead screw 10 or the transverse lead screw 5 has been adjusted, tightening the locking nut 33 will, in conjunction with the locking bolt 32, press the U-shaped clamp 31 into place, thus fixing the longitudinal lead screw 10 or the transverse lead screw 5. This prevents the longitudinal lead screw 10 or the transverse lead screw 5 from easily moving and affecting production. When adjustment via the longitudinal lead screw 10 or the transverse lead screw 5 is needed, simply loosen the locking nut 33.
[0038] This adjustable universal fixture for EPS electric steering column can clamp one end of workpiece 34 to the longitudinal clamping seat 9 using quick clamp 28 during operation; and clamp the other end of workpiece 34 to the U-shaped vertical plate 18 of the transverse clamping seat 3 by inserting a standard pin 23 into the workpiece 34. In this way, the universal fixture can perform the clamping operation of workpiece 34.
[0039] When the adjustable universal auxiliary fixture of the EPS electric steering column requires a ring shape, the lateral position of the lateral clamp 3 can be controlled by the lateral lead screw 5, and the longitudinal position of the longitudinal clamp 9 can be controlled by the longitudinal lead screw 10. In this way, it can meet the usage requirements of clamping various types of workpieces 34.
[0040] This adjustable universal fixture for EPS electric steering columns is compact and ingeniously designed, and can adapt to the clamping work of various models of EPS electric steering columns. This solves the problem of high strength when using existing EPS electric steering column fixing fixtures, and is particularly suitable for the clamping needs of EPS electric steering columns.
