Adopt above technical scheme, connect dish and be connected with the main shaft of lathe, pull bar is by hydraulic oil cylinder driving.In the time that pull bar travels forward, positioning sleeve travels forward with pull bar with terminal pad, two pawl arms are under the drive of terminal pad, pin joint around its rear end in moving forward turns an angle, two jaws are opened, now can be by special-shaped parts such as automobile shifting blocks by being put in the front end of longitudinal register piece, and the boss on special-shaped part is stretched in the locating slot on longitudinal register piece, carry out centralized positioning, finally drive pull bar to move backward, make two pawl arms drive jaw to close reset, briquetting on two jaws is pressed on special-shaped part, can complete clamping.As can be seen here, the utility model can be by part fast, clamping puts in place like a cork, operate very simple and convenient, and the fastness of parts fixation and good reliability.Jaw and chuck overall separation, change like parts when needs and add man-hour, only needs knockout screw to change jaw, longitudinal register piece and located lateral piece, greatly shortened and changed the time of fixture and the clamping time of workpiece, effectively improved working (machining) efficiency.
Front portion at described positioning sleeve (8) is formed with annular boss, the front portion of described terminal pad (9) is set on this annular boss, step inclined-plane in terminal pad (9) is spacing by the arc surface on annular boss forward, be provided with compression plate (11) at the rear of described terminal pad (9), it is upper that this compression plate (11) is locked at positioning sleeve (8) by the first nut (12), and the rear end face of compression plate (11) compressing terminal pad (9).Above structure is simple compact on the one hand, takes up room little, is easy to assembling; On the other hand, terminal pad is oppressed by compression plate, and adopts inner inclined-plane to coordinate with the arc surface on positioning sleeve, the locate mode of terminal pad is the location of floating, there is trickle activity surplus, even when part to be processed like this has dimensional discrepancy, still can guarantee the fixing of clamping.
The spindle nose of described pull bar (3) front end is spacing by the step surface in positioning sleeve (8) backward, by thread bush, the second nut (13) is housed at the rear portion of pull bar (3), and this second nut (13) is near the rear end face of positioning sleeve (8).Above structure is not only easy to assembling, and positioning sleeve and pull bar be connected firmly, not pull bar generation axial float relatively of positioning sleeve.
The front end of described positioning sleeve (8) stretches in the upper gathering sill arranging of front shroud (5), and this gathering sill leads to seesawing of positioning sleeve, makes positioning sleeve motion more smooth and easy.
Have bar shaped pilot hole (10a) at the postmedian of described pawl arm (10), the middle part of pin (14) is arranged in this pilot hole (10a), and the two ends of pin (14) and front shroud (5) fix.Above structure is in the time of terminal pad band pawl arm, and pin matches with bar shaped pilot hole, and guiding pawl arm track on demand moves, thereby has further improved speed and the reliability of clamping parts.
Beneficial effect: the utility model utilizes special-shaped part, and width and the thickness of machine-shaping are realized clamping, can be by part fast, clamping puts in place like a cork, be convenient to realize automation, manless production, there is the features such as easy to operate, clamping is firm, replacing fixture is convenient.
