Description
Technical field
The present invention relates to field of machining, specifically refer to the clamping and positioning device of blanking machine.
Background technology
Blanking machine is the indispensable equipment of some light industries, is to stress on cutting die by means of the active force of machine movement, material is carried out to the machine of cutting processing.Can be divided into swing arm blanking machine according to frame mode, punched part is the rocking arm that can swing, and is suitable for the die-cut of natural material; Planer-type blanking machine, punched part is the cutting head that can move left and right along crossbeam, cutting die can be fixed on cutting head, also can be placed on machined object, the gantry cutting machine drift of large-scale, conputer controlled is installed with rotatable cutting die frame, according to program typesetting, corresponding cutter can be selected; Flat blanking machine, it is die-cut that the difference of it and planer-type blanking machine is that crossbeam directly carries out, and do not have transportable cutting head, dull and stereotyped blanking machine is divided into again: the two large classes that crossbeam is fixed or crossbeam can move forward and backward and table slide can move forward and backward.
Usually, in process, workpiece is because of by cutting force, the effect of the power such as inertia force and change in location occurs or causes vibration, destroys original accurate location, needs to grip it.Traditional clamping device, as mechanical grip mechanism, Pneumatic clamping mechanism, but its driving force is little, unstable during work, the mechanical grip that bolt is fixed easily causes Workpiece vibration because of cutting, mutually collides finally to make to clamp to loosen with mechanism, and reliability sharply declines; Most serious of all, the noise produced during Pneumatic clamping mechanism work is large, have impact on operating efficiency to a great extent.
Summary of the invention
The present invention, by arranging the clamping and positioning device of blanking machine, solves the problem of traditional clamping device poor stability, reaches the object of stability and high efficiency processing.
Object of the present invention reaches by the following technical programs:
The present invention includes clamping unit, guide rail and bearing support, guide rail and clamping unit are all placed on bearing support, described clamping unit comprises sideboard and fixed dam, sideboard is slidably arranged on guide rail, fixed dam is arranged on bearing support, also comprise hydraulic mechanism and detent mechanism, described hydraulic mechanism is connected with the bottom of sideboard, and detent mechanism and clamping unit be arranged in parallel.On bearing support, sideboard and fixed dam form one can change clamping gap clamping unit according to the profile size of workpiece, arrange fixed dam can play position-limiting action to workpiece, sideboard can under the promotion of hydraulic mechanism fast advance and retreat to clamp workpiece or to unclamp; When carrying out blank operation, fixed dam inwall is close to by workpiece, and sideboard is close to fixed dam under the promotion of hydraulic mechanism output, until clamped by workpiece, finally carries out machining by cutting mechanism to workpiece; The employing of hydraulic mechanism solves the unstability of traditional mechanical grip and the larger noise problem of pneumatic gripper mechanism grips generation, also maintains good operating environment, improve operating efficiency while ensureing reliable clamping degree; The setting of detent mechanism, except guaranteeing to keep correct moving direction before workpiece enters clamp system, also can cut time fixation workpiece, avoid workpiece occur significantly vibrate.
Further, described hydraulic mechanism comprises hydraulic cylinder and hydraulic motor, and hydraulic cylinder is arranged on in the same level at sideboard place.Unstable and the Pneumatic clamping of clamping for mechanical grip easily produces the defects such as noise, in same level, hydraulic energy is changed into mechanical energy and exports by hydraulic motor, and hydraulic cylinder output drives sideboard to keep stable velocity interpolation fast to come and go rectilinear motion acting.
Further, described guide rail is U-shaped groove, and hydraulic cylinder output is connected with the bottom of sideboard through one end of U-shaped groove, and the other end of U-shaped groove is connected with fixed dam.Sideboard is slidably arranged on U-shaped groove, and the opening part of U-shaped groove can connect active catch panel seat straight line back and forth movement for hydraulic cylinder output, is beneficial to and increases work efficiency.
Further, as preferably, described guide rail material is cast iron.Because sideboard slides for a long time on guide rail, friction between guide rail and sideboard is caused constantly, to cause the irregular of guide level, affect clamping effect; The guide rail of cast iron quality, have certain anti-wear performance, and it is cheap, wide material sources, practicality is high.
Further, also comprise and be arranged on sideboard just to the multiple studs on fixed dam side.In clamping process, for ensureing to clamp efficiency better, the stud that sideboard inwall is arranged can be engaged workpiece, increases the frictional force between sideboard and workpiece, avoids the mutual collision caused when cutting mechanism cuts between workpiece and baffle plate.
Further, described detent mechanism comprises fixed block, movable block and slideway, and fixed block is arranged on bearing support, and movable block is connected with slideway by bolt.Movable block is slidably arranged on slideway, is fixed by bolt, changes spacing between fixed block and movable block according to the random adjusting bolt of the large I of the profile of workpiece with this.
Further, the multiple shockproof feet be arranged on bottom bearing support is also comprised.During cutting; a larger interaction force all can be produced between cutting mechanism and workpiece, between workpiece and bearing support; the interaction force of generation can balance out by the shockproof feet be arranged on bottom bearing support, protects clamping device further, 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, guide rail and bearing support, guide rail and clamping unit are all placed on bearing support, described clamping unit comprises sideboard and fixed dam, sideboard is slidably arranged on guide rail, fixed dam is arranged on bearing support, also comprise hydraulic mechanism and detent mechanism, described hydraulic mechanism is connected with the bottom of sideboard, and detent mechanism and clamping unit be arranged in parallel.The setting of detent mechanism, except guaranteeing to keep correct moving direction before workpiece enters clamp system, also can cut time fixation workpiece, avoid workpiece occur significantly vibrate.
2, detent mechanism of the present invention comprises fixed block, movable block and slideway, fixed block is arranged on bearing support, movable block is connected with slideway by bolt, movable block is slidably arranged on slideway, be fixed by bolt, change spacing between fixed block and movable block according to the random adjusting bolt of the large I of the profile of workpiece with this.
