Description
Technical field
The utility model relates to a kind of locking device, is specifically related to the locking device of moving-member on a kind of machine tool guideway.
Background technology
In commercial Application, lathe is the machine that metal blank is processed into machine parts, is the machine of making machine, in general machine-building, the labor content that lathe is undertaken accounts for machine and always makes 40～60% of workload, plays significant role in the national economic modernization construction.
Along with the development of Machine Manufacturing Technology, Digit Control Machine Tool becomes the main body of machining, in process, Digit Control Machine Tool needs clocklike to do relative motion between its each part, for this reason, all be provided with guide rail structure on the bed piece, to support and the guiding moving-member; Wherein, rolling guide because of it has that frictional force is little, light, the movement sensitive of starting, steadily, advantage such as precision stability is good, be widely used in the Digit Control Machine Tool, as the guiding support of moving-member.
Existing guide rail structure mainly is made up of the slide block 12 of guide rail bar 11 and cooperation referring to shown in the accompanying drawing 1, and described guide rail bar 11 is fixed on the bed piece 1; But relative motion between guide rail bar 11 and the slide block 12, moving-member 2 is positioned on the slide block 12, and moves around along guide rail bar 11 by slide block 12.In actual process, usually moving-member need be fixed on certain machining position, and in the prior art, for non-servo-drive and need at the tight motionless moving-member of any positional lock, as lathe tailstock parts, centre frame parts etc., its all difficult realization that be locked.
At the problems referred to above, the latch segment annex has been invented by part guide rails manufacturer, coupling mechanism force is applied directly on guide rail bar or the slide block, to realize the locking of guide rail.Yet this type of latch segment all damages guide rail bar or slide block easily, is unfavorable for the permanent use of guide rail; And the general more complicated of above-mentioned latch segment accessory structure, and price is high.
Summary of the invention
The utility model purpose provides a kind of locking device that is used for machine tool guideway of simple in structure, easy to make, reliable lock.
For achieving the above object, the technical solution adopted in the utility model is: a kind of locking device that is used for machine tool guideway, comprise clamp mechanism and be parallel to the steel band that the guide rail direction is provided with, described clamp mechanism comprises train wheel bridge, bolt and lower plate, described train wheel bridge is positioned at the below of moving-member and fixedlys connected with it, described lower plate is positioned at the below of train wheel bridge, is provided with circumferential location structure between lower plate and the train wheel bridge; The head of described bolt is stuck on the moving-member, and its threaded portion is passed moving-member successively, train wheel bridge is threaded with lower plate; One side of described steel band is fixedlyed connected with bed piece, and opposite side is between lower plate and train wheel bridge; The thickness of steel band is 0.3～1mm.
In the technique scheme, the center of top of the described lower plate formation bumping square that raises up, described train wheel bridge is provided with the groove that cooperates with described bumping square, constitutes described circumferential location structure.Described circumferential location structure is that lower plate is relative with train wheel bridge to be rotated in order to limit, and guarantees under the rotation of bolt, can drive lower plate and realize moving up and down.Certainly, also can adopt other circumferential location structure.Being not limited to squarely such as described bumping square, can be rectangle, hexagon or semicircle etc.
In the technique scheme, described steel band is 2, is symmetrically set in the both sides of clamp mechanism.
In the technique scheme, the bottom surface of described train wheel bridge is concordant with the upper surface of steel band.Be that steel band is not when clamped, the bottom surface of train wheel bridge is concordant with the upper surface of steel band, certainly, preferably situation is: the upper and lower surface of steel band is parallel with the clamping area of described upper and lower clamping plate and leave little clearance, is with the clamping area of upper and lower clamping plate and separates or local contact condition.Thereby when clamping steel band, steel band can produce slight strain, because the very thin thickness of steel band, the stress that distortion produces can not make near guide rail distortion it, thereby clamping force is dropped to minimum to the influence of guide precision, can ignore; After unclamping steel band, steel band reverts to original state, is between the clamping area of its upper and lower surface and upper and lower clamping plate and separates or local contact condition, can not produce bigger resistance to the motion of moving-member.
Operation principle of the present utility model is: when needing locking, and swivel bolt, lower plate can move straight up, and then the clamping steel band, fix moving-member, at this moment, moving-member, train wheel bridge, lower plate, steel band and bed piece are fixed together, thereby have realized the location of moving-member; Same, when unclamping, as long as swivel bolt unclamps, lower plate moves straight down, and then unclamps steel band, and moving-member can move back and forth along guide rail.
Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:
1, because the utility model is provided with locking device and steel band, realize the locking positioning of moving-member by clamping steel band, avoided coupling mechanism force to be applied directly on the guide rail and the injury that causes, thereby can use for a long time.
2, the utility model is simple in structure, the locking control operation is easy, and cheap, is fit to apply.
