Abstract
A milling cutter of a groove cutting machine is mainly characterized by comprising a cutter head (4), a milling cutter shaft (3) and a milling cutter (1), wherein a key slot (6) is formed by milling on the cutter head (4) and is used for being connected with a spindle (2); the milling cutter shaft (3) and the milling cutter (1) are connected onto the cutter head; the milling cutter shaft (3) is equipped with a thread sleeve (7) which is used for propping the milling cutter (1) to prevent the milling cutter (1) from shifting axially; and the fit clearance (5) of the inner hole of the milling cutter and the milling cutter shaft is about 3 mm.
Description
Technical field
The present invention uses on a kind of road surface, through adjustment groover cutter spindle and milling cutter fit clearance, guarantees that the road surface mills that milling cutter is not stuck when stitching.
Background technology
Highway, bridge etc. in use can produce the crack through rolling for a long time; In order to guarantee the highway life-span; Encapsulation process need be carried out in the crack, further handles well with the groover that rotary milling tools is housed earlier in the mending course to connect seam and crack, is the ready work of the pouring machine cementation of fissures.The fit clearance of most of rotary milling tools and cutter spindle is very little, has only about 0.50mm, and rotary milling tools is when joint-cutting; Occur the milling cutter stuck phenomenon easily, cutter spindle does not change relatively, causes milling cutter serious wear on one side; Wearing and tearing on one side are slight, and milling cutter forms ellipse, has influenced the cutting life-span of milling cutter greatly.
Summary of the invention
The present invention provides a kind of verticity good, the groover milling cutter of long service life.
Present invention be primarily characterized in that; The groover milling cutter comprises that being milled with keyway (6) on cutterhead (4), the cutterhead (4) is used for being connected with main shaft (2); Be connected in cutter spindle (3) and milling cutter (1) thereof on the cutterhead; On cutter spindle (3), be furnished with silk braid (7) and be used for withstanding milling cutter (1) and make it avoid doing axial float, the endoporus of milling cutter and the fit clearance of cutter spindle (5) are about 3mm.
The present invention is in the little deficiency of the fit clearance that has absorbed original rotary milling tools and cutter spindle, and designing its fit clearance is about 3mm, and milling cutter and cutter spindle are after assembling, and milling cutter can not be stuck.
Facts have proved that through construction milling cutter rotates good, milling cutter can not form ellipse after a large amount of the use, and obviously improve application life, improved working (machining) efficiency simultaneously, reduced construction cost.
Description of drawings
Fig. 1 is the utility model milling cutter assembly structure sketch map.
The specific embodiment
This instance is as shown in Figure 1; Comprise on cutterhead (4), the cutterhead (4) and be milled with keyway (6); Be connected in cutter spindle (3) and milling cutter (1) thereof on the cutterhead (4), on cutter spindle (3), be furnished with silk braid (7) and be used for withstanding milling cutter (1) and make it avoid doing axial float, said cutterhead (4) is assemblied on the main shaft (2).The fit clearance (5) of the endoporus of milling cutter (1) and cutter spindle (3) is 3mm.
When groover was started working, ato unit drove main shaft through belt driving band and rotates, and cutterhead is to be connected through flat key with main shaft, so cutterhead rotates at the same rate, and the drive milling cutter cuts the crack.Milling cutter cutting crack is to lean on six groups of milling cutters successively to impact ground with inertia force to accomplish joint-cutting.Because the fit clearance of milling cutter endoporus and cutter spindle reaches 3mm, milling cutter rotates at the relative cutter spindle of moment that impacts ground, the stuck not rotation phenomenon of milling cutter can not occur.
Claims (1)
1. its characteristic of groover milling cutter mainly is; Comprise that being milled with keyway (6) on cutterhead (4), the cutterhead (4) is connected with main shaft (2); Cutter spindle (3) and milling cutter (1) thereof are connected on the cutterhead, and silk braid (7) is housed on cutter spindle (3), and the endoporus of milling cutter and the fit clearance of cutter spindle (5) are 3mm.
