In the gluing process, the clamping mechanism 8, the stress mechanism 2, the distance tolerance mechanism 7 and the tensioning block 6 are all fixed with a lower end module 93 of the gluing tool, when gluing is carried out, an upper end module 1 of the gluing tool is pressed downwards, the upper end of the stress rod senses the downward pressure of the upper end module 1 of the gluing tool to drive the pressing block 21 to move downwards, the pulling rope 3 is tensioned, the pulling rope 3 transmits the pulling force to the upper fixing seat 81 after passing through the distance tolerance mechanism 7 to enable the upper fixing seat 81 to move downwards to complete the clamping of the tail door inner plate 5, when the pressing block 21 moves downwards, the distance between the pressing block 21 and the hook B71 is shortened, the spring D moves backwards under the pulling force of the pulling rope B31 to pull the pulling rope A32, when the tail door inner plate 5 reaches the limiting part C41, the distance tolerance mechanism 7 can eliminate excessive stroke while transmitting the force, the motion stroke of the stress mechanism 2 is always larger than that of the clamping mechanism 8, and the part is always clamped, the elasticity of the spring D is larger than the deformation force of the lock hole 51 of the inner plate 5 of the plastic tail gate and smaller than the gravity of the upper end module 1, after the gluing is finished, the upper end module 1 of the gluing tool is lifted, the pressure of the stress column 24 disappears, the press block 21 moves upwards under the action of the spring C22, the pulling force of the pull rope 3 on the upper fixing seat 81 is simultaneously removed, and the clamping mechanism 8 is restored to the original state before the clamping.
In order to avoid the problem that the gravity of the upper end module 1 of the gluing tool cannot pull the upper fixing seat 81 downwards and the gravity of the upper end module 1 can control the deformation force of parts and cannot overcome the friction force because the friction force of the four-bar hinge 86 and the plastic tail door inner plate 5 is continuously increased in the opening process of the four-bar hinge 86, the upper fixing seat 81 and the lower fixing seat 82 of the clamping mechanism 8 are designed into an integral movable structure.
In order to control the sequence of the movement of the upper fixing seat 81 and the lower fixing seat 82, the restoring force of the spring A84 is smaller than that of the spring B85, so that the upper fixing seat 81 moves downwards first and the lower fixing seat 82 moves downwards later.
The pull rope 3 is preferably a steel rope, a steel rope sleeve is arranged on the outer side of the steel rope between the pressing block 21 and the rear-side tensioning portion 61, two ends of the steel rope sleeve are respectively connected with the lower surface of the pressing block 21 and the right side surface of the rear-side tensioning portion 61, and the steel rope penetrates through the steel rope sleeve.
The sizes of all parts in the invention are designed according to the specific conditions of the gluing tool and the tail door inner plate 5 needing to be clamped.
In the prior art, a plastic tail gate is a closed cavity part, and has no abundant space for turning and clamping, so that the rebound deformation of the part cannot be eliminated; the part rocks when the rubber coating, and the size is unstable after plastics tail-gate bonding is accomplished. The clamping tool for the inner plate of the plastic tail door is installed in a gluing tool for the plastic tail door, when a robot places an upper end module 1 of the gluing tool, the upper end module 1 presses a stress column 24 of a stress mechanism 2, the stress column 24 is stressed to drive a pressing block 21 to move downwards, a steel cable is pulled, a distance tolerance mechanism 7 is pulled by the steel cable, and then a clamping mechanism 8 is pulled, so that plastic tail door parts are stably kept at correct positions, the stability of the parts is improved, and the size of a plastic tail door gluing assembly product is improved.
The advantages of using the invention are:
1. the dimensional stability of a single assembly part is good, and the one-time qualification rate is high;
2. the consistency of parts in different batches is good;
3. the part has less glue at the overflow part and less repair workload;
4. the repair time of the bicycle size is short;
5. the number of scrapped parts is small due to the size;
6. the tool is low in cost and reliable in structure.
The present invention is capable of other embodiments, and various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the invention.
