The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further.
Circle shear cutting edge side clearance guiding mechanism as shown in Figure 1 comprises that rotation is supported in the duct of casing 13 and the axial main shaft 9 of activity, and the front end of described main shaft 9 is equipped with cutter head 10, and the rear end of described main shaft 9 is connected with the movable end of linear electric motors 2.Main shaft 9 drives by linear electric motors 2 and carries out axially-movable, effectively eliminates the adjustment error that the motion conversion produces, and has realized the high precision in control that side clearance is adjusted, and has improved cutterhead service life, has improved shearing quality.
As shown in Figure 1, in order to prevent the axial float of main shaft 9 in the shear history, described main shaft 9 is supported in the duct of casing 13 by fore bearing assembly and the rotation of rear bearing assembly, in described fore bearing assembly adopts, the preceding cylindrical roller bearing 12 that axially moves about relatively in the outer ring, described rear bearing assembly is by interior, back cylindrical roller bearing 5 that axially moves about relatively in the outer ring and the double-direction thrust ball bearing 6 that is axially fixed on the main shaft 9 are formed, described double-direction thrust ball bearing 6 is by the axial prestrain of pre-tightening apparatus, described back cylindrical roller bearing 5 and double-direction thrust ball bearing 6 are installed in the support set 4, the hole wall axial sliding fit in described support set 4 and described duct, the movable end of described linear electric motors 2 is connected with support set 4.In this structure, the axial limiting of main shaft 9 is born by double-direction thrust ball bearing 6 fully, and the radially spacing of main shaft 9 born by preceding cylindrical roller bearing 12 and back cylindrical roller bearing 5 fully, because double-direction thrust ball bearing 6 is by the axial prestrain of pre-tightening apparatus, eliminate the end-play of this double-direction thrust ball bearing 6, therefore also just eliminated the problem of the axial float of main shaft 9 in the shear history.
As shown in Figure 1, as the concrete structure of above-mentioned pre-tightening apparatus, described pre-tightening apparatus adopts spring 7, and support set 4 is provided with inner cap 8, and described spring 7 is pressed between double-direction thrust ball bearing 6 and this inner cap 8.This pre-tightening apparatus simple in structure, and can be good at eliminating the end-play of double-direction thrust ball bearing 6.
As shown in Figure 1, as the concrete structure of preceding cylindrical roller bearing 12 and back cylindrical roller bearing 5, described before cylindrical roller bearing 12 do not have the biserial cylindrical roller bearing of rib for the outer ring, its outer ring is axially fixed on the duct, inner ring is axially fixed on the main shaft 9; Described back cylindrical roller bearing 5 does not have the single-row cylindrical roller bearing of rib for inner ring, and its outer ring is axially fixed on the support set 4, and inner ring is axially fixed on the main shaft 9.Because preceding cylindrical roller bearing 12 does not have the biserial cylindrical roller bearing of rib for the outer ring, its outer ring is axially fixed on the duct, and inner ring is axially fixed on the main shaft 9, so its outer ring is relative roller and inner ring axial float.Because back cylindrical roller bearing 5 does not have the cylindrical roller bearing of rib for inner ring, its outer ring is axially fixed on the support set 4, and inner ring is axially fixed on the main shaft 5, so its inner ring is relative roller and outer ring axial float.Adopt said structure can either be convenient to make the side clearance adjustment of main shaft 9 axially-movables carrying out circle shear, the radial location precision of cylindrical roller bearing 12 and 5 pairs of main shafts 9 of back cylindrical roller bearing before can guaranteeing again.
As shown in Figure 1, in order after adjusting, support set 4 to be axially fixed in the duct, prevent that 9 pairs on main shaft from making linear electric motors 2 produce bigger axial compressive force, is provided with the locking device that is used to lock support set 4 in the hole wall in described duct.As the concrete structure of locking device, described locking device comprises plunger case 14, and described plunger case 14 is connected with hydraulic system.Piston rod radial compaction support set 4 in the hydraulic system drive post plug cylinder 14 plays the locking effect to support set 4.
As shown in Figure 1, as to improvement of the technical scheme, described linear electric motors 2 adopt linear servo-actuators, need not the automatic control that other control elements can be realized adjustment process.
Embodiment
The stiff end of linear electric motors 2 is fixed on the casing 13 by bracing frame 1, movable end directly and movable sleeve 3 link, movable sleeve 3 and support set 4 are connected by bolt.Back cylindrical roller bearing 5 and double-direction thrust ball bearing 6 are housed on the support set 4, and an end of main shaft 9 is sleeved in back cylindrical roller bearing 5 and the double-direction thrust ball bearing 6 and is supported in the support set 4.Double-direction thrust ball bearing 6 carries out prestrain to guarantee assembly precision by one group of spring 7, and main shaft 9 one shaft shoulders nestle up double-direction thrust ball bearing 6.Main shaft 9 then uses preceding cylindrical roller bearing 12 to be connected with casing 13 near an end of cutter head 10.Cutter head 10 one sides lean against on the main shaft shoulder block simultaneously uses cutterhead locking nut 11 to lock, this locking nut need not extraneous pressurization, only need tighten or unclamp its nut that carries and lock or get loose, after cutterhead is refaced, need not to carry out cushioning, only need readjust and get final product side clearance.After adjusting side clearance, support set 4 locking is prevented that in shear history main shaft produces play and linear electric motors bear axial force by plunger case 14 at every turn.This kind adjusted simple, easy to maintenance, the no motion conversion links of form structure, no accumulated error, and the adjustment precision is the kinematic accuracy of linear electric motors 2 self under the ideal situation of cutting disc end face run-out.This structure influences all mechanical factors that linear electric motors 2 side clearances are adjusted precision from designing to have eliminated, and has fundamentally improved the adjustment precision.
