Description

Technical Field

[0001] The invention relates to the technical field of bushings, and in particular to a detection mechanism for a supporting bushing on a shock absorber. Background Art

[0002] The bushing supported on the car's shock absorber can withstand tension and compression, thereby effectively attenuating the vibration and noise transmitted from the road surface through the wheels. Figure 6 As shown, it can be used in new energy vehicles and self-driving cars. After the bushing is formed by the vulcanizer, it will be placed in the reducing machine to reduce the diameter to stabilize the structure. Later, it will need to be tested for diameter, ovality, and pressure. The staff needs to pick up the bushing and place it on the telescopic positioning column in front of the diameter gauge. The telescopic positioning column is manually extended upward so that the bushing is directly in front of the diameter gauge (the positioning column without the bushing cannot be directly in front of the diameter gauge to prevent the diameter gauge from detecting the positioning column). The motor drives the positioning column to rotate with the bushing, and the diameter gauge detects the diameter and ovality of the bushing. After the motor stops, the telescopic positioning column is manually retracted. Then the staff takes the bushing to the positioning block of the pressure detector and positions it. The pressure detector performs pressure detection on the bushing. The staff not only needs to take and place the bushing, but also needs to extend and retract the positioning column. At the same time, they need to pay attention to the test results to eliminate unqualified bushings, which is time-consuming, labor-intensive and inefficient. Summary of the invention

The bushings at the baffle plate, the first positioning column, the diameter positioning component, and the pressure positioning member are equidistantly distributed and correspond to the clamping claw cylinder. The right opening of the slide 14 is hinged with a hinged plate 15 driven by a push-pull cylinder 16. If the pressure detector and the diameter gauge fail to meet the test, the unqualified cylinder will be moved to the slide. When the cylinder is above, the cylinder pulls the hinge plate to rotate along the hinge point. The unqualified cylinder falls onto the slideway and slides to other places through the hinge plate and the opening. The pressure positioning member 8 is slidably matched with the machine frame 1 by moving forward and backward. The front and rear sides of the diameter positioning assembly 7 are provided with a diameter gauge 9. The rear side of the pressure positioning member 8 is provided with a pressure detector 10. The upper end of the machine frame 1 is provided with a limit block 20 for limiting the front and rear positions of the pressure positioning member 8, and a rotating member 12 driven by the first servo motor 11. The lower end of the rotating member 12 is rotatably provided with a toggle member 13 connected to the rotating member 12 through a torsion spring. A shifting assembly 17 for driving the horizontal plate 18 to shift is provided at the top of the frame 1, and a clamping cylinder 19 is equidistantly provided at the lower end of the horizontal plate 18. The rotating member 12 first drives the bushing to rise through the diameter positioning assembly 7, and at the same time stops the toggle member 13 after rotation to drive the pressure positioning member 8 and the bushing thereon to move back to the bottom, and the rotating member 12 then drives the bushing to rotate through the diameter positioning assembly 7, the diameter gauge 9 and the pressure detector 10 respectively detect the two bushings, and then the reversed rotating member 12 brings the toggle member 13, the diameter positioning assembly 7 and the pressure positioning member 8 to reset.The bushing is placed on the first conveyor belt, and the bushing transported to the right is blocked and positioned by the baffle. The shifting assembly drives the cross plate and the clamping claw cylinder to clamp the bushing and shift it to the right. The bushing is positioned at the first positioning column, the diameter positioning assembly, and the pressure positioning piece. The first servo motor drives the rotating part to rotate. The rotating part first drives the bushing to rise through the diameter positioning assembly. At the same time, the rotating part rotates the toggle piece through the torsion spring. The toggle piece drives the pressure positioning piece and the bushing thereon to move back to the bottom. The pressure positioning piece is limited by the limit block and the toggle piece stops. The rotating part drives the bushing to rotate through the diameter positioning assembly again. The diameter gauge performs diameter and ovality detection on the bushing on the diameter positioning assembly, and the pressure detector performs pressure detection on the bushing on the pressure positioning piece. Then the first servo motor drives the rotating part to reverse, and the rotating part reverses and resets with the toggle piece. The toggle piece drives the pressure positioning piece to move forward and reset. The pressure positioning piece is limited by the limit block, and the diameter positioning assembly and the bushing thereon are reset. The shifting assembly drives the cross plate and the clamping claw cylinder to clamp the bushing and move it one position to the right.

[0032] See also Fig.11 , Fig.14 The rotating member 12 is composed of a cam 12.1 in the middle, a cylinder 12.3 on the lower side, and an incomplete gear 12.2 on the upper side. The cam 12.1, the incomplete gear 12.2, and the cylinder 12.3 are arranged coaxially. A rotating groove 12.4 is provided on the outer wall of the cylinder 12.3. The toggle member 13 rotates in the rotating groove 12.4. The lower end of the cam 12.1 is vertically provided with a limit bar 12.5 that abuts against the toggle member 13. When the rotating member rotates, the cam drives the second positioning column and the bushing thereon to rise to the top, and at the same time, the toggle member is rotated with the toggle member through the torsion spring. The toggle member drives the pressure positioning member to move back to the bottom, and the toggle member does not move. The incomplete gear drives the first gear to rotate, thereby driving the second positioning column and the bushing thereon to rotate. Then the rotating member reverses, and the incomplete gear drives the first gear to reverse and separate. Then the second positioning column and the bushing thereon descend and reset under the action of gravity. The limit bar pushes the toggle member to reverse and reset, and the toggle member drives the pressure positioning member to move forward and reset.

[0033] The diameter positioning assembly 7 includes a guide sleeve 7.5 vertically arranged on the upper end of the frame 1, a guide post 7.4 is slidably mounted on the guide sleeve 7.5, and an elastic member connecting the guide post and the guide sleeve is arranged inside the guide sleeve, so that the second positioning post and the bushing thereon are more stable, a frame plate 7.3 is horizontally arranged at the top of the guide post 7.4, and a second positioning post 7.1 which is rotatably arranged in the middle of the frame plate 7.3 and is supported on the working surface of the cam 12.1, and a first gear 7.2 driven by an incomplete gear 12.2 is arranged at the lower end of the second positioning post 7.1. The second positioning post rises to the top along the guide post through the cam, and then the incomplete gear drives the first gear to rotate with the second positioning post and the bushing thereon, and the diameter gauge detects the diameter and ovality of the bushing, and then the rotating part is reversed, and the incomplete gear drives the first gear to reverse and separate, and the second positioning post and the bushing thereon are lowered and reset.

A fixed column 8.5 accommodating the movement of the toggle member 7 is vertically provided at the front end of the movable groove 8.4. The positioning ring is used to position the bushing. The circular groove allows the inner tube of the bushing to be pressed down to descend. The toggle member that rotates with the rotating member through the torsion spring moves the fixed column backward, thereby moving the pressure positioning member and the bushing thereon backward to the bottom. The toggle member does not move, and the pressure detector performs pressure detection on the bushing. Then the rotating member reverses, and the limit bar of the rotating member pushes the toggle member to reverse and reset. The toggle member moves the fixed column forward, thereby moving the pressure positioning member and the bushing thereon forward and reset.

[0035] The limit block 20 is composed of a middle longitudinal bar connecting the horizontal bars on the front and rear sides. When the pressure positioning piece 8 is against the front horizontal bar, the positioning ring 8.2 is located below the clamping jaw cylinder 19 so that the clamping jaw cylinder can shift the bushing on the positioning ring; when the pressure positioning piece 8 is against the rear horizontal bar, the positioning ring 8.2 is located below the pressure detector 10 so that the pressure detector can perform pressure detection on the bushing on the positioning ring, and the pressure column of the pressure detector applies a downward force to the inner tube of the bushing.

Shift gears are keyed on the two rotating shafts and the output shafts of the second servo motor. The three shift gears are connected by the first toothed belt. A shift rod 17.4 is keyed on the rotating shaft 17.3. The shift rod 17.4 is provided with a sliding hole along its length direction. A sliding column 17.5 slidably fitted in the sliding hole is slidably fitted in the guide hole, and a connecting block 17.6 connected to the cross plate 18 is vertically arranged at the rear end of the sliding column 17.5. A limit column that fits the lever is provided at the front end of the sliding column, and the rotating shaft is located at the longitudinal section of the guide hole. The second servo motor drives the lever to rotate through the rotating shaft, and the lever drives the sliding column and the connecting block to move along the guide hole. The connecting block moves along the guide hole with the cross plate and the clamping cylinder, thereby shifting the bushing along the baffle, the first positioning column, the second positioning column, the positioning ring, and the slideway.

[0037] It also includes a return assembly 21, which includes a second conveyor belt 21.6 arranged at the front side of the slideway 14.

Second frame strips are symmetrically arranged on both sides of the upper end of the second conveyor belt 21.6. The upper end surface of the second frame strip is flush with the upper end surface of the longitudinal section.

[0039] The upper end of the second frame strip on the front side is vertically provided with a stopper located at the front side of the slideway 2. The stopper can prevent the bushing that slides down from the slideway from falling out of the second conveyor belt.
