PURPOSE: A device for measuring the deformation of a bicycle frame is provided to automatically apply impact on a frame and automatically measure the information of the frame before and after applying impact on the frame, thereby simplifying a deformation measuring task in respect to the bicycle frame. CONSTITUTION: A device (1) for measuring the deformation of a bicycle frame includes a supporting unit (10), a pair of ball screws (20), a pair of guides (30), a motor driving unit (40), a weight (50), a lifting unit (60), a measuring device unit, a fixing unit (80), and a support unit (90). A plurality of supporting bars is mutually connected so that the support unit is formed. The ball screws include a screw thread on the outer circumferences thereof which are installed inside the support unit in the longitudinal direction. The guides are installed inside the support unit in the longitudinal direction. The motor driving unit is formed on the top surface of the support unit and is composed of a driving motor generating torque for generating a driving force; and an encoder (42) which is connected to the driving motor by a timing belt (3) and axially joined to each ball screw and rotates each of the ball screws. The weight is joined to the guides to be moved and has predetermined weight. |
