Description
Technical field
The utility model relates to a kind of gear rack center distance regulation mechanism.
Background technique
Traditional knife rest by guide rails assembling in frame, and by a set of actuating unit, by major axis by while be communicated to another side, because transmission distance is longer, each mechanical clearance and error cause two ends can not synchronizing moving, result two ends do not produce error on the same line, cause operative workpiece difficult quality guarantee even to occur waste product; Traditional drive unit is common motor, and due to knife rest quality weight, inertia is large, and knife rest easily causes positioning precision inaccurate in moving process.Existing gear rack matches and realizes knife rest and move, and along with service time is permanent, rack and pinion centre distance can become large gradually, causes gear rack excesssive gap, runs steady not, locates inaccurate.
Model utility content
For above-mentioned defect, it is simple that the purpose of this utility model is to provide a kind of structure, is convenient to adjustment gear rack centre distance, effectively prevents gear rack excesssive gap, operate steadily, a kind of gear rack center distance regulation mechanism of accurate positioning.
The technological scheme that the utility model adopts for this reason is:
Comprise the frame be arranged on base, described frame width direction installs a synchronous rotating shaft, synchronous rotating shaft two ends are arranged in the bearing support of frame both sides by bearing, voussoir is provided with below bearing support, described upper voussoir lower end is provided with the lower wedge block matched with upper voussoir, the outer end of described lower wedge block is connected with adjusting screw, upper end, described frame both sides is provided with linear rail, described linear rail is provided with the slide block being arranged on knife rest lower end, both sides, knife rest lower end surface are provided with tooth bar, synchronous rotating shaft is set with two synchromesh gears, two synchromesh gears are meshed with tooth bar respectively, one end of synchronous rotating shaft is connected with the output shaft of actuating motor by coupling.
Further, described two synchromesh gears lay respectively at the inner side of frame both sides.
Further, described synchromesh gear is connected by expansion sleeve with synchronous rotating shaft.
Further, the two ends of described synchronous rotating shaft are respectively equipped with end cover and are connected with frame side wall.
Further, the outer end of described lower wedge block is provided with contiguous block, and described adjusting screw is threaded with frame through contiguous block, and described adjusting screw is threaded with contiguous block.
The utility model has the advantages that:
The utility model structure is simple, easy to operate, by arranging synchromesh gear at synchronous rotating shaft two ends and tooth bar is meshed, ensure that synchronous rotating shaft two ends can synchronously drive knife rest to move, driving lower wedge block to move by turning adjusting screw, lower wedge block drives upper voussoir to move up, thus adjustment gear rack centre distance, ensure gear rack centre distance, stable movement, make knife rest positioning precision accurate, further ensure the quality of operative workpiece.
