Further, described driving mechanism comprises hydraulic cylinder, and hydraulic cylinder is arranged in the same level with portable plate place.For the clamping of mechanical grip, unstable and Pneumatic clamping easily produces the defects such as noise, and in same level, hydraulic cylinder changes hydraulic energy into mechanical energy output, and hydraulic cylinder output drives portable plate to keep stable speed fast to realize and comes and goes rectilinear motion acting.
Further, described slideway is U-shaped groove, and hydraulic cylinder output is connected through one end of U-shaped groove and the bottom of portable plate, and the other end of U-shaped groove is connected with fixed head.Portable plate is slidably arranged on U-shaped groove, and the opening part of U-shaped groove can supply hydraulic cylinder output connection activity panel seat straight line back and forth movement, is beneficial to and increases work efficiency.
Further, also comprise and be arranged on portable plate just to the multiple studs in fixed head one side.In clamping process, for guaranteeing better to clamp efficiency, the stud of portable plate inwall setting can be carried out interlock to bar material, increases the frictional force between portable plate and bar material, avoids causing the mutual collision between bar material and baffle plate in the time that cutting mechanism cuts.
Further, described detent mechanism comprises fixed block, movable block and slideway, and fixed block is arranged in frame, and movable block is connected with slideway by bolt.Movable block is slidably arranged on slideway, is fixed by bolt, changes the spacing between fixed block and movable block according to the random adjusting bolt of the large I of the profile of bar material with this.
Further, also comprise the multiple shockproof feet that is arranged on frame bottom.When cutting; between cutting mechanism and bar material, between bar material and frame, all can produce a larger interaction force; the shockproof feet that is arranged on frame bottom can balance out the interaction force of generation, protects further clamping device, extends its service life.
The present invention compared with prior art, there is following advantage and beneficial effect:
1, the present invention includes clamping unit, slideway and frame, slideway and clamping unit are all placed in frame, described clamping unit comprises portable plate and fixed head, portable plate is slidably arranged on slideway, fixed head is arranged in frame, also comprise driving mechanism and detent mechanism, described driving mechanism is connected with the bottom of portable plate, and detent mechanism and clamping unit be arranged in parallel.The setting of detent mechanism, except guaranteeing to keep correct moving direction before bar material enters clamp mechanism, also can be at when cutting fixed bar material, avoid bar material that significantly vibration occurs.
2, detent mechanism of the present invention comprises fixed block, movable block and slideway, fixed block is arranged in frame, movable block is connected with slideway by bolt, movable block is slidably arranged on slideway, be fixed by bolt, change the spacing between fixed block and movable block according to the random adjusting bolt of the large I of the profile of bar material with this.
