Abstract

The utility model discloses a knife lifting and lowering device for a linear motor. The knife lifting and lowering device comprises a bottom plate for fixing, a knife lifting and lowering mechanism fixed on the bottom plate, and a knife rest connected with the knife lifting and lowering mechanism, wherein, the knife lifting and lowering mechanism comprises a motor base, a linear motor and a guide rail rod; the linear motor is fixed on the motor base fixedly connected onto the bottom plate; the active cell of the linear motor is connected with one end of the guide rail rod through a connecting rod; the knife rest is fixed at the other end of the guide rail rod; and a spring is mounted on the guide rail rod and fixed onto the motor base connected with the bottom plate through a linear bearing. The knife rest is driven to vertically move by driving the guide rail rod through the linear motor, thereby greatly improving the knife lifting and lowering scope; and meanwhile, because the spring is mounted on the guide rail rod, the knife rest plays a certain buffer role, and simultaneously can vertically displace within a certain small amplitude and is suitable for platforms and inscribing materials with worse levelness, thereby reducing the number of defectives; and the knife rest is fixed on the guide rail rod by a jack screw, thereby facilitating the disassembly, assembly, the adjustment, and the use of users.

Description

Linear electric motors are lifted roll adjusting mechanism

Technical field

The utility model relates to a kind of linear electric motors that are used on the engraving machine device of plane and lifts roll adjusting mechanism.

Background technology

Existing platform is carved the equipment of painting, and it is lifted roll adjusting mechanism and designs with the solenoid principle.Being used for platform, to carve when painting its roll setting scope too narrow and small, to platform and carved the flatness of being painted material and require too highly, adjusts relatively difficulty, paint material the quarter that flatness is not reached requirement, is easy to occur defect ware, promptly influenced efficient, increased again to carve and plotted this, very inconvenient client's use.

The utility model content

The utility model technical issues that need to address provide a kind of to platform with paint the material flatness quarter and require lowly, and the convenient linear electric motors that use of adjusting are lifted roll adjusting mechanism.

For addressing the above problem, technical solution adopted in the utility model is: a kind of linear electric motors are lifted roll adjusting mechanism, comprise the base plate that is used for fixing, be fixed on and lift roll setting mechanism on the base plate, the knife rest that is connected with this mechanism, the described roll setting mechanism of lifting comprises motor cabinet, linear electric motors, guide rail pole, described linear electric motors are fixed on the motor cabinet that is fixed on the base plate, the mover of linear electric motors links to each other with guide rail pole one end by connecting rod, guide rail pole other end immovable support, spring is housed on the guide rail pole, and by on the motor cabinet that linear bearing is fixed on base plate links to each other.

Also be provided with a guide rail pole on the described motor cabinet, guide rail pole is connected by rolling bearing with motor cabinet, and an end of this guide rail pole is fixed on the knife rest.

Described knife rest is fixed by jackscrew and guide rail pole.

Adopt the beneficial effect that technique scheme produced to be: basis is novel to move up and down by adopting linear electric motors driving guide rail pole to drive knife rest, improved the roll setting scope of lifting greatly, simultaneously because spring is housed on guide rail pole, make knife rest have certain cushioning effect, the upper and lower displacement of very little amplitude can be arranged simultaneously, can adapt to the relatively poor platform of flatness and paint material quarter, reduce the appearance of defect ware, knife rest is fixed on the guide rail pole with jackscrew, be beneficial to loading and unloading and adjustment, be user-friendly to.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:

As shown in Figure 1, 2, 3, this novel base plate 1 that comprises, and be installed on and lift roll setting mechanism on the base plate, wherein lift roll setting mechanism and comprise linear electric motors 8, guide rail pole 6, motor cabinet 4, linear electric motors 8 are fixed on the motor cabinet 4 by screw 13, motor cabinet 4 is fixed on the base plate 1, the mover of linear electric motors links to each other with an end of guide rail pole 6 by connecting rod 3, guide rail pole 6 slides up and down under linear electric motors 8 drive by the linear bearing 12 that is fixed on the bearing block 5, drives the knife rest 2 that is fixed on guide rail pole 6 other ends and moves up and down.Bearing block 5 is fixed on the base plate 1, and spring 11 also is housed on guide rail, and the buffering when being used for knife rest and lifting is used for the servo-actuated fine setting of knife rest position simultaneously, to adapt to the relatively poor platform of flatness and to carve the requirement of painting material.In order to limit the rotary freedom of knife rest 2, more firm when making knife rest lift roll setting, rotation and shake can not appear, increased another root guide rail pole 7, one end immovable support 2 of guide rail pole 7, guide rail pole 7 can slide up and down under the drive of knife rest 2 by the bearing 9 that is fixed on the motor cabinet 4, and bearing 9 is fixed on the screwed shank of screw of front end, is fixed on the motor cabinet 4 by screw thread; Easy for installation in order to adjust, knife rest 2 is fixed on the guide rail pole 6,7 by jackscrew 10.
