[0020] The right end of the bottom plate 1 is provided with a cylinder fixing plate 27 which is matched with the bottom plate 1; the fastening cylinder 13 is arranged on the left side wall of the cylinder fixing plate 27; the right end of the fastening cylinder 13 and the cylinder fixing plate 27 are fixed through a plurality of uniformly distributed second screws 28.

[0021] The use method of the utility model is as follows:

[0022] When the coil winding 9 needs to be assembled and fixed in the diverter valve body 5, the fastening cylinder 13 can be directly started, at this time, the piston rod of the fastening cylinder 13 drives the fastening seat 15 to move leftwards, so that the left movement of the fastening arms 16 on the front and back sides is realized; when the fastening arms 16 move leftwards to a certain stroke, the limiting shaft 19 enters the U-shaped groove 17 which is formed by the fastening seat 15 and the fastening arms 16 on the front and back sides; with the continuous left movement of the fastening arms 16, the final extrusion slope 18 comes into contact with the outer edge of the upper surface of the limiting head 20; since the right end of the extrusion slope 18 is downwardly inclined, the pressure applied by the extrusion slope 18 to the outer edge of the upper surface of the limiting head 20 becomes greater when the extrusion slope 18 moves leftwards; when the limiting head 20 is pressed downwardly, the pressing head 12 arranged on the upper end of the fixed mandrel 11 is synchronously pressed downwardly, so that the pressing head 12 presses the lower end of the coil winding 9 in the sealing groove 8, thereby effectively ensuring the stability of the coil winding 9 at this moment; then, the sealing glue 10 can be added to the gap between the outer wall of the coil winding 9 and the inner wall of the diverter valve body 5 through a glue gun, so that the coil winding 9 is fixed in the diverter valve body 5 by the viscosity of the sealing glue 10, and the coil winding 9 cannot rotate upwardly, downwardly, leftwardly or rightwardly; when the pressing head 12 extrudes the coil winding 9 downwardly, the O-ring 25 located between the lower surface of the pressing part 24 and the groove bottom of the sealing groove 8 is synchronously extruded by the downward pressure, so that the O-ring 25 is fully deformed and seals the gap between the inner wall of the lead hole 22 and the outer wall of the sealing sleeve 23, thereby maximizing the sealing effect.

[0023] As can be known from the above, when the coil winding 9 is assembled into the steering valve body 5, only the fastening cylinder 13 needs to be started, and the fastening structure arranged at the left end of the piston rod of the fastening cylinder 13 can pull down and fix the core shaft 11, so as to pull down and press the lower pressing head 12, and the lower pressing head 12 extrudes the lower end of the coil winding 9 in the sealing groove 8. After the coil winding 9 is fixed, the sealing glue 10 can be used to bond and fix the coil winding 9 in the steering valve body 5. After the sealing glue 10 is solidified, even if the lower pressing head 12 no longer extrudes the coil winding 9 downward, the stability of the coil winding 9 in the steering valve body 5 can be ensured, the steering valve body 5 is prevented from rotating up and down and left and right, the situation that the force output by the steering device is large and small is avoided, the safety hidden danger is effectively eliminated, and the sealing effect of the O-shaped ring is effectively ensured, so that the situation that the steering device leaks oil after being installed on the automobile is effectively avoided.

[0024] When the coil winding 9 is assembled into the steering valve body 5, the piston rod of the fastening cylinder 13 can drive the fastening seat 15 and the front and rear fastening arms 16 to move rightward and reset. At this time, the fixed core shaft 11 is no longer limited, the assembled steering valve body 5 can be taken out from the positioning groove 3 on the upper surface of the positioning seat 2, and the fixed core shaft 11 can be pulled out from the steering valve body 5. Subsequently, the next assembly work can be started.

[0025] The lower end of the positioning seat 2 and the bottom plate 1 are fixed through a plurality of uniformly distributed first screws 26. This fixing mode not only can ensure the stability of the positioning seat 2, but also is beneficial to disassembly and assembly of the positioning seat 2, and is convenient for replacement and maintenance of the positioning seat 2.
