Abstract
The invention relates to a spiral limiting device used for a rotating shaft of a milling head. The spiral limiting device used for the rotating shaft of the milling head comprises a plurality of circles of spiral grooves, wherein the spiral grooves are fixed on the rotating shaft of the milling head in a coaxial mode, dragging bolts are imbedded into the spiral grooves, the dragging bolts can move in the spiral groove along the circumferences in the radial direction, the dragging bolts are connected with a sliding block, the sliding block is sleeved on a guide pillar, the guide pillar is fixed on a limit switch support, the two sides of the sliding block on the guide pillar are respectively provided with a spring in a sleeved mode, and a first limit switch and a second limit switch are installed on the limit switch support through fixing blocks respectively. According to the spiral limiting device used for the rotating shaft of the milling head, rotary motion is converted into radial linear motion, the stroke detection of a large-stroke rotary shaft is simplified, and a user can increase the stroke of the rotary shaft conveniently by increasing the number of the circles of the spiral grooves and the stroke of the sliding block. The spiral limiting device used for the rotating shaft of the milling head has the advantages of being simple in structure, high in reliability, and convenient to adjust and maintain.
Description
Technical field
The invention relates to a kind of screw type stopping means for the milling head rotating shaft, particularly a kind of stopping means of big stroke milling head rotating shaft.
Background technology
At present, the application of the rotating shaft of big stroke is more and more, all can be above ± 180 ° as the rotating distance of milling head rotating shaft.Because the rotating shaft stroke is partly or entirely overlapping, conventional triggering piece adds the stroke detection mechanism of detecting sensor combining form, can't correctly detect the extreme position of displacement in its whole stroke at all.Shortcomings such as what be usually used in the rotating shaft stroke detection is spiral, and stroke is little, and axial length is long, and poor reliability.
Summary of the invention
The purpose of the invention provides a kind of simple in structure, and reliability is high, is used for the big distance caging device of milling head rotating shaft.
The purpose of the invention is achieved through the following technical solutions: a kind of screw type stopping means for the milling head rotating shaft, it is characterized in that: comprise the coaxial some circle helicla flutes that are fixed on the milling head rotating shaft, in helicla flute, embed and drag screw, dragging screw can move radially along circumference in helicla flute, dragging screw links to each other with slide block, slide block set is on lead, lead is fixed on the limit switch bracket, on lead, the both sides of slide block are set with a spring, first limit switch, second limit switch is installed on the limit switch bracket by fixed block respectively.
Limit switch bracket links to each other with base, and base is fixed on the top shell of milling head rotating shaft.
The beneficial effect of the invention is: said structure is adopted in the invention, and helicla flute can rotate with the milling head rotating shaft, is embedded in to drag screw under spiral fluted drives, along moving radially of circumference in the helicla flute; Drag screw and slide block links together, thereby drive slide block along the reciprocal slip of lead.When rotating shaft reaches the limit of the position, slide block will slide into the position that can trigger limit switch, produces limit signal.The invention will rotatablely move and be converted into radially rectilinear motion, thereby simplify the stroke detection problem of big stroke rotating shaft.And can increase the stroke of rotating shaft easily by increasing the stroke of the spiral fluted number of turns and slide block.It is simple in structure, and the reliability height is adjusted easy to maintenance.

Fig. 2 is that the master of Fig. 1 looks partial cross sectional views.
Fig. 3 is the graphics of Fig. 1.
The specific embodiment
Embodiment to the invention specifically describes below in conjunction with accompanying drawing, as Figure 1-3, the stopping means structure that the invention is used for the milling head rotating shaft is as follows: be some circle helicla flutes 1 of spiral by the coaxial rotating shaft that is installed in milling head in seam location, it is together rotated with rotating shaft, in helicla flute 1, embed and drag screw 9, dragging screw 9 can move radially along circumference in helicla flute 1, dragging screw 9 links to each other with slide block 5, slide block 5 is enclosed within on the lead 8, lead 8 is fixed on the limit switch bracket 6, first limit switch 2, second limit switch 4 is installed on the limit switch bracket 6 by fixed block 3 respectively.
On lead 8, limit switch bracket 6 links to each other with base 10, and base 10 is fixed on the top shell of milling head rotating shaft.Slide block 5 reciprocatingly slides along lead 8 under the drive that drags screw 9, when rotating shaft moves to extreme position, slide block 5 also moves to the position of triggering first limit switch 2, second limit switch 4, for the movement position that guarantees slide block 5 accurate, on lead 8, the both sides of slide block 5 are set with a spring 7, when slide block 5 to center of circle direction motion, inboard spring pressurized, outside spring tension, make to drag screw 9 near the inboard of helicoid, on the contrary, then be adjacent to the outside of helicoid.This stopping means generally all is arranged on the top of milling head rotating shaft, and base 10 links to each other with limit switch bracket 6, and base 10 is fixed on the top shell of rotating shaft.
In this example, when rotating shaft clockwise rotates 360 °, drag screw 9 and enter into the spiral fluted inner lane from present position, coupled slide block 5 is along move to the center of circle distance of a helical pitch of lead 8, at this moment the position of slide block 5 and first limit switch 2 over against, produce triggering signal, rotating shaft stall or reverse rotation.At this moment, if rotating shaft is rotated counterclockwise 720 °, then drags screw 9 and enter into the spiral fluted outer ring.Slide block 5 is along lead 8 the slide distance of 2 helical pitches of the direction in the center of circle dorsad, the position of slide block 5 and second limit switch 4 over against, generation triggering signal, rotating shaft stall or reverse rotation.
Because the accuracy of this stopping means work depends on the grooved of helicla flute 1, the appearance and size of slide block 5 and the position of limit switch, therefore the machining accuracy at these several parts all need meet design requirement with installing to adjust.
