| Abstract: |
| An analysis of motional and mechanical characteristics for the diagonal four-point double-toggle clamp is made by the method of mechanics.The formulas for calculating the mold board stroke，the oil cy linder stroke，the speed variation coefficient，the clamping force and force amplification are derived and the direct calculating method for primary angles and critical angles is described.The theoretic basis of the clamp unit design is proposed. |
