Background technology
In prior art, transversal driving mechanism mainly adopts big take-up housing and small slide block to be fixed on the decimal control machine bottom board, give transverse arm positioning parts guiding, twin shaft heart slide rail is housed on the transverse arm parts, slide rail connects with slide block, twin shaft heart slide rail on the transverse arm parts is positioned in big take-up housing and the small slide block groove and slides, and driven wheel is installed in the stepper motor termination.Tooth bar is equipped with in transverse arm parts side, tooth bar and driven wheel engagement.The uncompensated function of rigidity is all adopted in gear, tooth bar engagement that existing flame, the little numerical control cutting machine of plasma drive, very high to guide rail and the required precision of tooth bar mount pad, otherwise shake and noise can appear in transmission process, influence cutting accuracy and cutting surface smoothness, particularly evident on CUT.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby provide a kind of requirement that can reduce processing and installation accuracy, reduce the device fabrication cost, improve cutting accuracy and fineness, the transversal driving mechanism of result of use on the little numerical control cutting machine of plasma.
The technical scheme that provides according to the utility model, transversal driving mechanism adopts big take-up housing and small slide block to be fixed on the decimal control machine bottom board, give transverse arm positioning parts guiding, twin shaft heart slide rail is housed on the transverse arm parts, slide rail connects with slide block, and the twin shaft heart slide rail on the transverse arm parts is positioned in big take-up housing and the small slide block groove and slides, and driven wheel is installed in the stepper motor termination, tooth bar is equipped with in transverse arm parts side, tooth bar and driven wheel engagement.Feature is: described stepper motor is installed on the motor fixing plate, motor fixing plate is installed on the cross motor bearing, on the described cross motor bearing fairlead is installed, and spring is equipped with in described motor fixing plate side, and be installed on the holder, holder is installed on the cross motor bearing.
Described motor fixing plate is provided with long lumbar hole.
Compared with the prior art the utility model has the following advantages:
Fairlead, spring have been adopted in the utility model mechanism, fairlead leads to motor fixing seat, spring spurs motor cabinet by screw rod always, make gear not have the gap all the time and be close to tooth bar, realize the transmission of no gap, when because mismachining tolerance or installation accuracy when causing that the rack-and-pinion back lash changes, spring can in time be recompensed, realize the engagement of evenly no gap, reduced required precision to processing and installation, reduced the device fabrication cost, improved cutting accuracy and fineness, result of use is good on the little numerical control cutting machine of plasma.
Description of drawings
Fig. 1 is the utility model structure user mode schematic diagram.
Fig. 2 is figure A～A cutaway view.
The specific embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
As Fig. 1～shown in Figure 2, comprise big take-up housing 1, screw 2, stepper motor 3, soket head cap screw 4, cross motor bearing 5, soket head cap screw 6, small slide block 7, driven wheel 8, interior hexagonal flush end holding screw 9, fairlead 10, soket head cap screw 11, motor fixing plate 12, spring 13, slotted cheese head screw 14, holder 15, soket head cap screw 16, transverse arm parts 17 and tooth bar 18 etc.
Big take-up housing 1 and small slide block 7 are used for fixing the slide block on the twin shaft heart slide rail in the utility model, be fixed on the little numerical control cutting machine base plate of plasma with screw 2, give transverse arm parts 17 positioning and guidings, twin shaft heart slide rail is housed on the transverse arm parts 17, slide rail connects with slide block, and the twin shaft heart slide rail on the transverse arm parts 17 is positioned in big take-up housing 1 and small slide block 7 grooves and slides.Be installed on the stepper motor 3 on the motor fixing plate 12, fastening with soket head cap screw 4, motor fixing plate 12 is installed on the cross motor bearing 5, and fairlead 10 usefulness soket head cap screws 11 are installed on the cross motor bearing 5, can move along positioning sleeve 10 vertical direction.Cross motor bearing 5 usefulness soket head cap screws 6 are installed on the little numerical control cutting machine base plate of plasma, spring 13 is equipped with in motor fixing plate 12 sides, and be installed on the holder 15 with slotted cheese head screw 14, holder 15 usefulness soket head cap screws 16 are installed on the cross motor bearing 5.The interior hexagonal flush end of driven wheel 8 usefulness holding screw 9 is installed in stepper motor 3 axle head heads, and stepper motor 3 drives driven wheel 8 and rotates, and driven wheel 8 rotates drive transverse arm upper rack 18 and moves, and tooth bar 18 drives transverse arms and moves.Tooth bar 18 is equipped with in transverse arm parts 17 sides, tooth bar 18 and driven wheel 8 engagements.Slotted cheese head screw 14 is used to regulate motor fixing plate 12, also is used to regulate the degree of driven wheel 8 and tooth bar 18 engagements simultaneously.
The utility model course of work and operation principle:
The big 0.1mm of fairlead guiding position aspect ratio motor fixing plate thickness in this mechanism, fairlead guiding diameter is ￠ 8
-0.035, long lumbar hole gets 8 on the motor fixing plate
+ 0.019With the M5 screw fairlead is fixed on the cross motor bearing, motor fixing plate can move along the fairlead vertical direction, work as gear, when the tooth bar engagement goes wrong, be Gear axis and tooth bar distance too hour, spring is compressed, gear can move to the direction away from tooth bar, and when Gear axis and tooth bar distance was too big, spring can promote the M5 screw, the gear fixed head is pulled to the tooth bar direction, make gear, the tooth bar back lash is reasonable, and the relative tooth bar of gear is in the elastic floating state, and gear can not change back lash with tooth bar because of the tooth bar precision, operation principle is to utilize the elasticity of spring, pushes away or draws motor fixing plate to move it.
