Description
TECHNICAL FIELD
[0001] The utility model belongs to the clamping tool technical field, concretely relates to a clamping device of parallel forging manipulator. BACKGROUND
[0002] Forging manipulator plays an important auxiliary equipment in forging production, and plays a key role in free forging stage. Its core role is to firmly clamp one end of the ingot or blank and drive it to move. This function replaces the heavy operation of manual work and relieves the workers from fatigue. Moreover, it greatly improves the production efficiency of forging machines.
[0003] At present, the clamps used by most forging manipulators are relatively common clamps. Such clamps have certain limitations in actual application. The structure of the common clamp is relatively mature for clamping circular forging blanks from the heating furnace and then free forging or stamping, but for rectangular forging blanks, there is not enough contact area and clamping force to take out the square blank when clamping. If the forging piece must be clamped, the power must be increased to generate stronger clamping force, which is easy to cause stress concentration and damage the forging piece. Therefore, the existing forging manipulator has the defect that the contact area and clamping force are insufficient when clamping the square blank, which is easy to cause stress concentration and damage the forging piece.

The rotating shaft is connected to one end of the rear parallel rod of the parallel clamping mechanism and can rotate. One end of the front parallel rod is connected to the front pin shaft hole provided at the front end of the shell through a pin shaft and can rotate. The other end of the front parallel rod is connected to the front pin shaft hole provided at the rear of the clamping rod through a pin shaft and can rotate.
