Referring to fig. 1 to 3, the present invention provides a tool bar clamp, including:
the mounting seat 100, the mounting seat 100 is provided with a blade mounting cavity;
a plurality of pressure heads 201 are arranged around the cutter bar installation cavity, and one end of each pressure head 201 close to the cutter bar installation cavity is close to the opening end of the cutter bar installation cavity relative to the other end;
the pressing plate 200, the one end of pressing plate 200 is connected with can take place elastic deformation's elastic component 202, and the middle section position of pressure head 201 is connected to the other end of elastic component 202, and the pressure plate 200 keeps middle section position or keeps away from the one end butt pressure head 201 of elastic component 202 through the effect of elastic component 202.
Because the main body part of the blade bar is in a quadrangular structure, in actual arrangement, four groups of pressing heads 201 can be arranged to respectively clamp one side surface of the blade bar, or an adaptive positioning structure can be arranged on the mounting seat 100, and the number of the groups of the pressing heads 201 is less than four.
Referring to fig. 2 and 3, the axis of the pressing head 201 is inclined to the left with respect to the vertical direction, and the pressing plate 200 may maintain the lower end surface horizontal, nearly horizontal, inclined to the left, or inclined to the right by the elastic member 202.
Adopt the tool section anchor clamps of above-mentioned structure setting, compress tightly the tool section through pressure head 201 control clamp plate 200, the centre gripping of adaptation tool section effectively, and the mode that clamp plate 200 compressed tightly the tool section both can effectively increase area of contact and improve the clamping force, also can avoid exerting pressure to the tool section part and cause the damage, the protection tool section, clamp plate 200 connects through elastic component 202 and keeps at the tip of pressure head 201, the mode of more fixed setting can swing the regulation, the centre gripping of adaptation tool section better. The pressure head 201 can adopt modes such as hydraulic pressure, pneumatics to drive and lock, and is reliable and stable, and its upper end is leaned left simultaneously for mount pad 100 can set up the structure of stepping down on the open end terminal surface of sword strip installation cavity, reserves the position for the installation of sword strip, the processing of sword strip, ensures going on smoothly of sword strip processing.
Referring to fig. 1 to 3, in some embodiments of the present invention, the blade mounting cavity is provided with two sets of V-shaped locating surfaces, and the indenter 201 is provided with two sets of V-shaped locating surfaces. In practical settings, the number of the pressing heads 201 in each group can be flexibly set according to needs, and in the embodiment, only one pressing head 201 is arranged in each group. Two pressure heads 201 are arranged on the side wall of the tool bar installation cavity opposite to the two end surfaces of the V-shaped positioning surface, so that a tool bar clamping area is formed between the two pressure heads and the V-shaped positioning surface. When the tool section is clamped, the pressing head 201 is in a retracted state, the tool section is firstly placed in the tool section mounting cavity and attached to the V-shaped positioning surface, and then the pressing head 201 is controlled to extend to clamp the tool section.
