Description
Technical field
The utility model is related to roller technical field, more particularly to a kind of roller devices for being conveniently replaceable roller.
Background technology
Because Digit Control Machine Tool track is very accurate, therefore, when Digit Control Machine Tool is moved, its track must obtain real-time, appropriate
Kind protection, conventional mode is to install that roller devices, protective cover are housed on slidable CNC Machine Tool Protective Cover, this protective cover
During slip, roller is rolled along roller track, but existing roller is typically directly to be arranged on protection shroud rim by welding manner
Groove in, because roller is running stores, long-term use necessarily causes abrasion, and when re-replacing roller, generally requires brokenly
Bad protective cover, one is to change that difficulty is big, cost is high, and two be that protective cover is caused to damage, and repairs pretty troublesome.Accordingly, it would be desirable to
A kind of roller devices for being conveniently replaceable roller of design.
Utility model content
The utility model aims to solve the problem that the deficiencies in the prior art, and provides a kind of roller devices for being conveniently replaceable roller.
The utility model to achieve the above object, using following technical scheme：
Described a kind of roller devices for being conveniently replaceable roller, it is characterised in that block, roller including flat, block
Body is the upper groove that a cuboid is provided with insertion front and back sides on top, and bottom is provided with the knot of the low groove of insertion left and right side
In structure, and upper groove and insertion above block, low groove and insertion below block, the block projection cube structure of the upper groove left and right sides
The screwed hole of left and right insertion is provided with, the threaded roller shaft in two is screwed with this screwed hole, roller is embedded with bearing, this bearing
Neck bush is in the middle part of roller shaft, and the top edge of roller is higher than the block projection cube structure of the upper groove left and right sides, roller shaft dew
Both ends outside block are provided with jump ring, be provided with the front and back sides low groove corresponding position of block it is some run through it is recessed
The rivet hole of groove.
Preferably, roller shaft two ends end face is provided with " ten " word or " one " word indentation.
Preferably, the material of block is aluminium alloy.
Preferably, roller shaft upper roller both sides are cased with copper sheet.
The beneficial effects of the utility model are：Roller, roller bearing are designed to detachable by the utility model, facilitate user to exist
Self-changeable roller when roller weares and teares, substantially reduces maintenance difficulty and cost, while will not cause any to protective cover
Damage.
Brief description of the drawings
Fig. 1 is front view of the present utility model；
Fig. 2 is right view of the present utility model.
In figure：1- blocks；2- upper grooves；3- low grooves；4- rollers；5- copper sheets；6- roller shafts；7- jump rings；8- rivet holes.
It is described in detail referring to the drawings below with reference to embodiment of the present utility model.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples：
As depicted in figs. 1 and 2, a kind of roller devices for being conveniently replaceable roller, it is characterised in that the block including flat
1st, roller 4, block 1 is the upper groove 2 that a cuboid is provided with insertion front and back sides on top, and bottom is provided with insertion left and right side
Low groove 3 structure, and the insertion above of upper groove 2 and block 1, low groove 3 and the insertion below of block 1, upper groove 2 or so two
It is provided with the projection cube structure of block 1 of side in the screwed hole of left and right insertion, this screwed hole and is screwed with the threaded roller shaft 6 in two, is rolled
Wheel 4 is embedded with bearing, and the neck bush of this bearing is at the middle part of roller shaft 6, and the top edge of roller 4 is higher than the upper groove 2 or so two
The projection cube structure of block 1 of side, the both ends that roller shaft 6 is exposed at the outside of block 1 are provided with jump ring 7, recessed in the front and back sides of block 1
The corresponding position of groove 3 is provided with some rivet holes 8 for running through low groove 3.
Preferably, the two ends end face of roller shaft 6 is provided with " ten " word or " one " word indentation, is easy to use screwdriver dismounting roller shaft
6。
Preferably, the material of block 1 is aluminium alloy.
Preferably, the both sides of 6 upper roller of roller shaft 4 are cased with copper sheet 5, and copper sheet 5 plays the positioning action of pair roller 4 and prevented
Mutual abrasion between roller 4 and block 1.
Application method：Protection shroud rim is placed in low groove 3, is fixed on block 1 through rivet hole 8 using rivet anti-
On shield, when roller 4 reaches that operating limit needs replacing, jump ring 7 need to only be removed, roller shaft 6 is extracted out, old rolling is removed
Wheel 4, new roller 4 is enclosed on roller shaft 6, then roller shaft 6, jump ring 7 are set back.
The utility model is exemplarily described above in conjunction with accompanying drawing, it is clear that the utility model implement not by
The limitation of aforesaid way, if the various improvement that method design of the present utility model and technical scheme are carried out are employed, or without
Improvement directly applies to other occasions, within protection domain of the present utility model.
