Description

TECHNICAL FIELD

[0001] The utility model relates to clamp technical field, in particular to a compression device. BACKGROUND

[0002] The front and rear door plate assembly, the engine cover assembly and the tail door assembly in the automobile body-in-white are all welded together with the inner plate and the outer plate edge covering, and the positioning reference of the assembly is normally on the inner plate, and the clamp needs to realize the clamping function of the assembly part on the gauge. The common method is to use a push-pull type compression, that is, to use a push-pull type quick clamp for compression. However, since the clamp head of the existing push-pull type quick clamp can only move forward, the push-pull type quick clamp can only be arranged on the periphery of the assembly to compress the outer plate to realize positioning. When the inner plate needs to be used as a zero positioning compression to realize the positioning of the assembly part, if the push-pull type quick clamp is still used for compression, since the clamp head of the push-pull type quick clamp can only move forward, the push-pull type quick clamp needs to be arranged on the inner side of the assembly, so that the clamp head can compress the inner plate, but the outer plate will form a closed type, which will cause the push-pull type quick clamp distributed on the inner side to be unable to be operated, so the inner plate cannot be compressed.

[0003] The prior art discloses a strong and large-stroke push-pull clamp (CN211135377U), which comprises a base, a rocker, a push rod, a connecting rod and a sliding rod. The base is used for providing an installation position, and a top surface and a sliding groove with an open end are arranged in the base. The open end in the sliding groove is hingedly connected with the bottom end of a V-shaped rocker. One top end of the rocker is detachably connected with the bottom end of the push rod, and the other top end is hingedly connected with one end of the connecting rod. The other end of the connecting rod is hingedly connected with one end of the sliding rod. A through hole is formed in one end of the base opposite to the open end of the sliding groove. The other end of the sliding rod passes through the through hole and slides in the through hole. A connecting hole is formed in the other end of the sliding rod for connecting an external clamp. Since the sliding rod can only move forward when the push rod is rotated, the push-pull clamp can only be arranged on the outer side of the assembly to compress the outer plate. When the push-pull clamp of the patent is arranged on the inner side of the assembly to compress the inner plate, it cannot be operated. CONTENT OF THE UTILITY MODEL
