A mounting plate 8 is connected to the operating table 5 through a reciprocating drive mechanism and a telescopic connecting rod 7, and tightening seats 81 are provided on both sides of the inner end of the mounting plate 8. A tightening plate 9 is embedded and slidably installed on the inner end of the tightening seat 81. A contact plate 11 is connected to the inner side of the tightening plate 9 through a movable rod 10, and a rubber pad 12 is fixed to the inner side of the contact plate 11; the reciprocating drive mechanism includes a gear 61 and an arc-shaped rack 62 that mesh with each other, and the gear 61 and the arc-shaped rack 62 are both embedded and rotatably installed in the operating table 5, the gear 61 is driven by a motor, and the inner wall of the arc-shaped rack 62 is fixedly connected to the telescopic connecting rod 7;

[0031] The one-way tightening assembly is arranged between the telescopic connecting rod 7 and the mounting plate 8, and is used to realize the one-way tightening of the tightening plate 9. The one-way tightening assembly includes a resistance column 141, and the resistance column 141 penetrates the telescopic part installed on the telescopic connecting rod 7. The first resistance plate 142 and the second resistance plate 143 are respectively arranged on both sides of the moving track of the resistance column 141. The first resistance plate 142 and the second resistance plate 143 are respectively fixed on the left and right sides of the inside of the operating table 5. The first piston rod 144 is fixed on both sides of the resistance column 141 through a rod. The first piston rod 144 is located in the oil tank 145.

[0032] The bottom of the fixed part of the telescopic connecting rod 7 is provided with a protrusion that fits and slides in the auxiliary support groove 71. The auxiliary support groove 71 is provided inside the operating table 5. The auxiliary support groove 71 is designed as an arc structure corresponding to the arc rack 62. The inner end of the rubber pad 12 is designed as an inclined surface structure, and the inclined surface of the rubber pad 12 is arranged from the inside to the outside.

[0033] The driving mechanism drives the movable seat 3 to rotate, rotates the operating platform 5 to the corresponding position, and pushes the operating platform 5 towards the machine shell bolt through the electric push rod 4. The contact plate 11 on the tightening plate 9 approaches the bolt. The rubber pad 12 contacts the bolt through the inclined surface. The bolt head is clamped by the two contact plates 11 and the rubber pad 12. Then, the motor drives the gear 61 to rotate reciprocally. The arc-shaped rack 62 and the telescopic connecting rod 7 drive the mounting plate 8 to rotate reciprocally. The mounting plate 8 moves to the right to perform the tightening operation on the bolt. The abutting column 141 touches the second abutting plate 143. The contraction of the telescopic connecting rod 7 drives the mounting plate 8 to move outward. At the same time, the first piston rod 144 moves in the oil tank 145, squeezing the oil into the oil cavity 146. The second piston rod 147 drives the movable head 148 to move outward, thereby driving the two tightening plates 9 to move away from each other, causing the rubber pad 12 to separate from the bolt head. Then, the arc-shaped rack 62 drives the mounting plate 8 to move to the left through the telescopic connecting rod 7. The internal damping connection of the telescopic connecting rod 7 enables the mounting plate 8 to temporarily maintain its original position. When the mounting plate 8 moves to the left area, the abutting column 141 touches the first abutting plate 142, causing the telescopic connecting rod 7 and the mounting plate 8 to extend and reset, and further causing the two contact plates 11 and the rubber pad 12 to clamp the bolt head again.

[0034] Embodiment 2: On the basis of Embodiment 1, please refer to Figures 1-2 and Figures 5-6 , the width adjustment mechanism is arranged in the tightening seat 81 and the tightening plate 9. The width adjustment mechanism is used to adjust the distance between the two tightening plates 9; the width adjustment mechanism includes a first screw rod 131, which is horizontally rotatably arranged in the moving groove 132. The moving groove 132 is opened at the inner end of the tightening seat 81. The first screw rod 131 is threadedly sleeved with the tightening plate 9. A straight rack 133 is slidably and embeddedly arranged in the tightening plate 9 through a spring. The inner end of the straight rack 133 is engaged with a gear roller 134. A second screw rod 135 is connected to the gear roller 134. The second screw rod 135 is threadedly sleeved with the movable rod 10; the first screw rods 131 in the two tightening seats 81 are nested and installed with each other. The nested part of the first screw rod 131 is designed as a rectangular structure; the end surface of the moving groove 132 is designed as an inclined structure to abut against the straight rack 133. The second screw rod 135 drives the movable rod 10 to fit and slide in the cavity on the inner side wall of the tightening plate 9;

[0035] According to the specifications of the bolt, adjust the distance between the tightening plates 9 in the two tightening seats 81. Rotate the first screw rod 131. The thread directions of the first screw rods 131 in the two tightening seats 81 are opposite, which can drive the two tightening plates 9 to move relative to each other. The tightening plate 9 slides in the moving groove 132. The straight rack 133 abuts against the inclined surface of the moving groove 132, which can drive the straight rack 133 to move, and further drive the gear roller 134 and the second screw rod 135 to rotate, adjusting the positions of the two contact plates 11 so that the contact plates 11 move in the opposite direction to the tightening plates 9.

[0036] Working principle: First, according to the specifications of the bolts, adjust the distance between the tightening plates 9 in the two tightening seats 81. Rotate the first screw rod 131. The thread directions of the first screw rods 131 in the two tightening seats 81 are opposite, which can drive the two tightening plates 9 to move relatively. The tightening plates 9 slide in the moving grooves 132. The straight rack 133 abuts against the inclined surface of the moving groove 132, which can drive the straight rack 133 to move, and then drive the toothed roller 134 and the second screw rod 135 to rotate, adjusting the positions of the two contact plates 11, so that the contact plates 11 move in the opposite direction to the tightening plates 9. That is, when the distance between the two tightening plates 9 is farther, the contact plates 11 and the rubber pads 12 move inward for a certain distance, so that the rubber pads 12 are squeezed tighter when contacting the bolts. When performing flexible assembly through the rubber pads 12, the clamping force can be changed according to the size of the bolts, so as to increase the tightening degree while ensuring flexible tightening;

[0037] After adjustment, stack the reducer housing and the motor housing on the positioning and mounting seat 2, install the bolts, drive the movable seat 3 to rotate through the driving mechanism, rotate the operating platform 5 to the corresponding position, and push the operating platform 5 towards the bolt of the housing through the electric push rod 4. The contact plates 11 on the tightening plates 9 approach the bolts, contact the bolts through the inclined surfaces of the rubber pads 12, clamp the bolt heads through the two contact plates 11 and the rubber pads 12, and then drive the gear 61 to rotate reciprocally by the motor. The arc-shaped rack 62 and the telescopic connecting rod 7 drive the mounting plate 8 to rotate reciprocally. The mounting plate 8 moves to the right to tighten the bolts. The contact post 141 touches the second contact plate 143, and drives the mounting plate 8 to move outward through the contraction of the telescopic connecting rod 7. At the same time, the first piston rod 144 moves in the oil tank 145, squeezing the oil into the oil cavity 146, driving the movable head 148 to move outward through the second piston rod 147, and then driving the two tightening plates 9 to move away from each other, so that the rubber pads 12 are separated from the bolt heads. Then the arc-shaped rack 62 drives the mounting plate 8 to move to the left through the telescopic connecting rod 7. The inside of the telescopic connecting rod 7 is connected with damping, so that the mounting plate 8 temporarily maintains its original position. The mounting plate 8 moves to the left area, and the contact post 141 touches the first contact plate 142, so that the telescopic connecting rod 7 and the mounting plate 8 extend and reset, and then the two contact plates 11 and the rubber pads 12 clamp the bolt heads again, and as the mounting plate 8 moves to the right again, tighten the bolts. Repeat the above operations to automatically tighten the bolts. And when tightening finally, the force deformation of the rubber pads 12 can achieve flexible tightening and avoid damage.
