The frame 4 is provided with a workpiece seat 5 (see figure 1 of the specification); the workpiece seat 5 packages the supporting seat 11, the supporting plate 14 and the clamping pin 13 (see fig. 2 of the specification).
The frame 4 is provided with a supporting seat 11; a clamping pin 13 is obliquely arranged on the frame 4 at one side of the supporting seat 11 through a supporting rod 12; a supporting plate 14 is arranged on the frame 4 at the other side of the supporting seat 11; the support plate 14 is provided with a support arc 15 (see fig. 2 of the specification).
The purpose of the work piece holder 5 being so arranged is that: when the device works, the R-EPS steering gear (workpiece) can be placed on the supporting seat 11 and the supporting plate 14 under the cooperation of the clamping pin 13, and the clamping pin 13 is in clamping connection with the R-EPS steering gear (workpiece); after the installation, the motor 2 on the R-EPS steering gear (workpiece) is positioned at the outer sides of the supporting seat 11 and the supporting plate 14, and when the steering gear is in such a way, the steering gear body 1 is kept motionless due to the limitation of the supporting seat 11 and the supporting plate 14; when the motor 2 is stressed outwards, the motor and the steering gear body 1 move outwards relatively, so that the adjustment of the motor 2 can be completed.
The workpiece holder 5 is provided with a regulator 6 on the inside (see fig. 1 and 7 of the specification). The adjuster 6 includes a mount 16, a longitudinal slide 17, an upper clamping jaw 19, a lower clamping jaw 20, and a bi-directional cylinder 21 (see fig. 3 of the specification).
The frame 4 is provided with a mounting seat 16; the mounting seat 16 is provided with a longitudinal sliding seat 17 through a guide rail; the mounting seat 16 is provided with an adjusting screw rod 18 through a motor; the adjusting screw 18 is connected with the longitudinal slide 17 (see fig. 3 of the specification); the adjusting screw 18 can control the longitudinal sliding seat 17 to slide back and forth on the mounting seat 16 when working.
An upper clamping claw 19 and a lower clamping claw 20 are slidably arranged on the longitudinal sliding seat 17 through guide rails; the upper clamping jaw 19 and the lower clamping jaw 20 are interconnected by a bi-directional cylinder 21 (see fig. 3 of the description). The bidirectional cylinder 21 is operative to drive the upper clamping jaw 19 and the lower clamping jaw 20 to slide up and down on the longitudinal slide 17.
An upper limit block 22 is arranged on the longitudinal sliding seat 17 above the upper clamping claw 19, and a lower limit block 23 is arranged on the longitudinal sliding seat 17 below the lower clamping claw 20; an upper positioning block 24 is arranged on one side of the upper clamping jaw 19, and a lower positioning block 25 is arranged on one side of the lower clamping jaw 20 (see fig. 3 and 4 of the specification). When the bidirectional cylinder 21 is fully unfolded, the upper positioning block 24 of the upper clamping claw 19 is in abutting connection with the upper limiting block 22, the lower positioning block 25 of the lower clamping claw 20 is in abutting connection with the lower limiting block 23, the upper clamping claw 19 and the lower clamping claw 20 are in the maximum opening state, and when the bidirectional cylinder 21 works to drive the upper clamping claw 19 and the lower clamping claw 20 to be close, the motor 2 can be clamped and fixed.
A bracket 7 (see figure 1 of the specification) is arranged on the frame 4 at one side of the regulator 6; the bracket 7 is provided with a transverse sliding seat 8 through a sliding rail and a cylinder; an electric cylinder 9 is arranged on the transverse sliding seat 8; the end of the electric cylinder 9 is equipped with a detection ram 10 (see fig. 6 of the specification) by means of a pull pressure sensor. When the pressure head 10 is stressed, the electric cylinder 9 can drive the detection pressure head 10 to move up and down, the displacement distance of the electric cylinder 9 can be recorded through the encoder, and the stress condition of the electric cylinder can be recorded through the tension pressure sensor.
According to the belt tensioning and adjusting device of the R-EPS steering gear, the motor 2 and the belt 3 are firstly preassembled on the steering gear body 1 during operation, at the moment, the assembly bolts between the motor 2 and the steering gear body 1 are not screwed, so that the motor 2 can move relative to the steering gear body 1 when being stressed, and the distance between the belt pulley on the steering gear body 1 and the belt pulley on the motor 2 can be adjusted when the motor 2 moves, so that the purpose of adjusting the tensioning force of the belt 3 is achieved.
After the motor 2 and the belt 3 are preassembled on the diverter body 1, the diverter body 1 is placed on the workpiece seat 5. The motor on the adjuster 6 then drives the longitudinal slide 17, the upper clamping jaw 19 and the lower clamping jaw 20 via the adjusting screw 18 towards the motor 2 on the diverter body 1, the longitudinal slide 17 being deactivated when the motor 2 is located between the upper clamping jaw 19 and the lower clamping jaw 20. The upper clamping jaw 19 and the lower clamping jaw 20 are then brought together by the bi-directional cylinder 21, clamping and fixing the motor 2.
After the motor 2 is clamped and fixed by the upper clamping claw 19 and the lower clamping claw 20, the electric cylinder 9 can drive the detection pressure head 10 to move downwards for a certain distance and then reset. In the process that the detection pressure head 10 moves downwards to contact with the belt 3, the force of the detection pressure head 10 extruding the belt 3 is the tension of the belt, and the tension can be detected by a tension pressure sensor connected with the detection pressure head 10.
After the process is finished, the screw rod 18 is adjusted according to the detection data of the tension of the belt, the motor 2 is driven to move relative to the steering gear body 1 through the longitudinal sliding seat 17, the upper clamping claw 19 and the lower clamping claw 20, the motor 2 is enabled to move to a proper position, then the detection pressure head 10 detects the tension of the belt 3 again, and the operation is repeated until the motor 2 is adjusted to the proper position, so that after the tension of the belt 3 is in a qualified range, the assembly bolt between the motor 2 and the steering gear body 1 is screwed. The two-way cylinder 21 then drives the upper clamping jaw 19 and the lower clamping jaw 20 to loosen the motor 2, and the longitudinal slide 17 drives the upper clamping jaw 19 and the lower clamping jaw 20 to reset, and then the assembled R-EPS steering gear is disassembled, so that the belt tensioning adjusting device of the R-EPS steering gear completely completes the adjustment work of the belt tensioning, and the adjusting device can enter the next working cycle.
The belt tensioning and adjusting device of the R-EPS steering gear is compact in structure and ingenious in design, and can mechanically complete the adjustment work of the belt of the R-EPS steering gear, so that the problem of high labor intensity existing in the existing belt 3 adjustment mode of the R-EPS steering gear is solved, and the belt tensioning and adjusting device is particularly suitable for the requirement of tensioning and adjusting the belt 3 of the R-EPS steering gear.
