Abstract
The utility model relates to a diamond roller locking device which is characterized in that an expanded sleeve with a taper hole and a conical adapter sleeve matched with the expanded sleeve are respectively arranged in the centre holes at both ends of a roller; the expanded sleeve and the adapter sleeve are both provided with elastic and deformable longitudinal incisions; a main shaft of the device is respectively provided with flanges and nuts for firmly abutting a contractive sleeve and the expanded sleeve at both ends. The device can make the inner bores of the diamond roller and the main shaft of the device tightly fitted and concentric, so the radial bouncing of the roller is small and the running is stable, which enables the diamond working layer of the roller to be full utilized and extends the service life of the roller by 20 to 50%. Meanwhile, the loading and the unloading of the roller become more convenient, and the utility model is favorable for protecting the main shaft of the user device.
Description
Technical field
The utility model relates to the locking device that the fit structure of hole and axle, particularly diamond running roller and rolling axle cooperate.
Background technology
The diamond running roller is a kind of big specification diamond abrasive tool, and its profile is cylindric, is made up of matrix and diamond working layers.Be mainly used in the large tracts of land grinding of hard brittle materials such as refractory material, vitreous china, require the surface necessary smooth smooth.The domestic and international at present diamond running roller of manufacturing, its axle all is directly to cooperate by certain tolerance with the hole.Because easily wearing and tearing in rolling axle, hole, causes fit clearance excessive, are difficult to guarantee concentricity, thereby cause the running roller circular runout.Not only have a strong impact on the ground effect of diamond running roller, and diamond working layers can't be fully used.If fit clearance is too small, because diamond running roller weight is big (general 〉=as 50kg), to cause very difficulty of diamond running roller loading and unloading.Present in a word assembling mode or cause the diamond running roller normally not use, or influence its service life.Often reduce 20-50% than normal condition actual life.
Summary of the invention
The purpose of this utility model is to avoid the above-mentioned difficulties of prior art, and a kind of diamond running roller locking device is provided, and running roller endoporus and main shaft is closely cooperated and concentric, make again install easy and convenient.
Solution of the present utility model is: the expansion sleeve of a band bellmouth and the taper adapter sleeve that cooperates with it respectively are set in the centre bore at existing running roller two ends; All have the longitudinal cut of strain on expansion sleeve and the adapter sleeve; Be respectively equipped with on the machine spindle and push against flange and the nut that cover, expansion sleeve are shunk in two ends.
The utility model compared with prior art has following advantage:
1. diamond running roller endoporus is closely cooperated and concentric with machine spindle, during use the running roller circular runout little, running is stable.
2. because the diamond running roller does not produce circular runout, the diamond working layers of running roller is fully used, its life-span can prolong 20-50%.
3. the contraction cover of diamond running roller locking device and expansion sleeve radial-deformation are about 0.5mm, the loading and unloading running roller is become easily, and help protecting the subscriber equipment main shaft.
4. when adopting this running roller locking device, need not transform existing equipment and technical process, simple.
Description of drawings
Fig. 1 is the overall structure schematic diagram of diamond running roller locking device.
Fig. 2 is the profilograph of adapter sleeve.
Fig. 3 is the upward view of Fig. 2.
Fig. 4 is the profilograph of expansion sleeve.
Fig. 5 is the upward view of Fig. 4.
The specific embodiment
Referring to Fig. 1, the adapter sleeve 4 that an expansion sleeve 3 respectively is housed in the centre bore at diamond running roller 1 two ends and matches with it.The endoporus of adapter sleeve 4 cooperates with subscriber equipment main shaft 2, and its outer wall is smooth cone, cooperates with the inwall of the bellmouth 9 of expansion sleeve 3.Expansion sleeve 3 cylindricals cooperate with diamond running roller endoporus.
Referring to Fig. 3, Fig. 5, adapter sleeve 4 and expansion sleeve 3 longitudinally promptly axially all have elastomeric slit 6.The effect of otch is to make adapter sleeve and expansion sleeve be easy to take place strain.For the adapter sleeve 4 and the expansion sleeve 3 that can compress two ends, be provided with flange 5 in main shaft 2 upper roll wheels left side, running roller right side main shaft is provided with screw thread and clamp nut 7, packing ring 8 etc.When screwing nut 7 generation axial pressing forces, adapter sleeve 4 radial contraction produce tight fits with machine spindle 2.Expansion sleeve 3 swells simultaneously, closely cooperates with the running roller centre bore, and diamond running roller 1 is propped up in equilibrium, thereby has accurately guaranteed the concentricity of running roller and machine spindle, thereby helps improving ground effect, and makes assembling become easy.
Claims (1)
