Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Example 1

[0022] Please see Figure 1-5 This utility model provides a car bumper riveting clamping assembly, including a car bumper riveting operating table 1. An mounting plate 2 is installed inside the car bumper riveting operating table 1. Two sets of positioning processing areas are arranged along the central axis at the top of the mounting plate 2. Each processing area has a mounting block 3 symmetrically arranged and fixedly connected to the top of the mounting plate 2. A flexible pad 4 made of flexible material is fixedly connected to the top of each mounting block 3. Each of the two sets of positioning processing areas is equipped with three main clamping components 5. Each main clamping component 5 includes a first cylinder 501, a hinge shaft 502, a connecting arm 503, and a positioning clamp 504. Each of the two sets of positioning processing areas is equipped with... Three first cylinders 501 are provided. The bottom end of each first cylinder 501 is fixedly connected to the top end of the mounting plate 2, and the output end of the first cylinder 501 is hinged to the middle of the hinge shaft 502. The hinge shaft 502 is hinged inside the connector, and both ends of the hinge shaft 502 are fixedly connected to one end of the connecting arm 503. The other end of the connecting arm 503 is fixedly connected to the positioning clamp 504. A limiting block 6 with a "convex" structure is fixedly connected to the first cylinder 501 near the outer wall of the positioning clamp 504, and a locking block 7 with a "concave" structure is locked at the top of the limiting block 6. The locking block 7 is fixedly connected to the bottom end of the connecting arm 503.

[0023] Because the top of the mounting plate 2 has two sets of positioning processing areas set along the central axis, this device can process two car bumpers simultaneously. During use, the car bumper to be riveted is placed above the flexible pad 4, and then the top outer wall of the car bumper is clamped by the three main clamping components 5 in each positioning processing area. Specifically, the first cylinder 501 outputs the work vertically, and the output end of the first cylinder 501 drives the hinge shaft 502 to rotate, so that the connecting arm 503 moves in an arc around the hinge shaft 502. This causes the positioning clamp 504 to move in an arc simultaneously. When the snap-fit ​​block 7 and the limiting block 6 snap into each other and limit each other, the positioning clamp 504 abuts against the top surface of the car bumper, thus completing the clamping operation. This method provides a more stable fixing effect. At the same time, the flexible pad 4 reduces the excessive clamping force on the bumper, thus preventing dents.

[0024] Each of the two sets of positioning and processing areas is equipped with two first auxiliary clamping components and two second auxiliary clamping components. The two first auxiliary clamping components are located between the two second auxiliary clamping components. The first auxiliary clamping component includes a second cylinder 8, a first auxiliary clamp 9, and a first balloon block 10. The top of each of the two sets of positioning and processing areas is symmetrically and fixedly connected to the second cylinder 8. The second cylinder 8 has a front and rear output. The output end of the second cylinder 8 is fixedly connected to the first auxiliary clamp 9 with an "L"-shaped structure. The first balloon block 10 is fixedly connected to the outer wall of the first auxiliary clamp 9 near the main clamping component 5. The second auxiliary clamping component includes a third cylinder 11, a second auxiliary clamp 12, and a second balloon 13. The top of each of the two sets of positioning and processing areas is symmetrically and fixedly connected to the third cylinder 11. The third cylinder 11 has a vertical output. The output end of the third cylinder 11 is fixedly connected to the second auxiliary clamp 12. The bottom outer wall of the second auxiliary clamp 12 is fixedly connected to the second balloon 13.

[0025] When the car bumper is placed on top of the flexible pad 4, the second cylinder 8 in the first auxiliary clamping assembly outputs an operation, driving the first auxiliary clamp 9 and the first balloon block 10 to abut against the outer wall of the car bumper and push the car bumper to the designated area. Then, the third cylinder 11 in the second auxiliary clamping assembly drives the second auxiliary clamp 12 to move vertically, so that the second auxiliary clamp 12 and the second balloon 13 abut against the top of the car bumper, thereby completing the positioning. This method can ensure that the car bumper is in the designated area after positioning, avoiding deviations caused by processing errors.

[0026] Limiting plates 14 are symmetrically fixedly connected to the top of both sets of positioning processing areas. The spacing between the limiting plates 14 fixedly connected to the top of each positioning processing area is adapted to the size of the car bumper. An X-axis transmission assembly 15 is fixedly connected to the top of the car bumper riveting operation table 1, and a Z-axis transmission assembly 16 is fixedly connected to the output end of the X-axis transmission assembly 15. An alarm indicator light 17 is fixedly connected to the top of the car bumper riveting operation table 1. Several control knobs 18 are fixedly connected to the front end of the car bumper riveting operation table 1. The control knobs 18 are electrically connected to the first cylinder 501, the second cylinder 8, the third cylinder 11, the X-axis transmission assembly 15, the Z-axis transmission assembly 16, and the alarm indicator light 17.

[0027] During use, the operator controls the first cylinder 501, the second cylinder 8, the third cylinder 11, the X-axis transmission assembly 15, the Z-axis transmission assembly 16, and the alarm indicator light 17 by manipulating the control knob 18. The limit plate 14 ensures that the position of the bumper does not deviate. The X-axis transmission assembly 15 and the Z-axis transmission assembly 16 work together to move the riveting machine and complete the riveting operation on the bumper. At the same time, the set PLC program monitors the operation. When an abnormality occurs, the alarm indicator light 17 will sound an alarm. The first cylinder 501, the second cylinder 8, and the third cylinder 11 all output according to the output values ​​preset by the PLC program, so that the clamping force generated by the positioning fixture, the first auxiliary fixture, and the second auxiliary fixture is adapted to the strength of the bumper and the required clamping force.

[0028] The specific usage process in this embodiment is as follows:

[0029] First, during use, place the car bumper to be riveted above the flexible pad 4, and ensure that the position of the bumper will not deviate through the limiting piece 14.

[0030] Secondly, the first auxiliary clamping assembly outputs the second cylinder 8 to drive the first auxiliary clamp 9 and the first balloon block 10 to abut against the outer wall of the car bumper and push the car bumper to the designated area. The second auxiliary clamp 12 is driven to move vertically by the third cylinder 11 contained in the second auxiliary clamping assembly, so that the second auxiliary clamp 12 and the second balloon 13 abut against the top of the car bumper, thereby completing the positioning.

[0031] Then, the first cylinder 501 outputs the work vertically, and the output end of the first cylinder 501 drives the hinge shaft 502 to rotate, so that the connecting arm 503 moves in an arc around the hinge shaft 502. This causes the positioning clamp 504 to move in an arc in sync. When the locking block 7 and the limiting block 6 lock together and limit each other, the positioning clamp 504 abuts against the top surface of the car bumper, thus completing the clamping operation.

[0032] Finally, the operator manipulates the control knob 18, and through the cooperation of the X-axis transmission component 15 and the Z-axis transmission component 16, moves the riveting machine to complete the riveting operation on the bumper. At the same time, the set PLC program completes the monitoring. When an abnormality occurs, the alarm indicator light 17 will sound an alarm. In this way, the use of a car bumper riveting clamping component is completed.
