Abstract
The utility model discloses a device for fixing a saw blade of a large-diameter bar grinding wheel saw, and belongs to the technical field machining equipment. The device is used for reusing the residual saw blade of the grinding wheel saw and improving the effective utilization area of the saw blade. The utility model adopts the technical scheme that: the device consists of an inner chuck, a grinding wheel main shaft sleeve, an outer chuck and an adapting sleeve, wherein the adapting sleeve is sleeved on the grinding wheel main shaft sleeve and positioned between the inner chuck and the outer chuck; a grinding wheel saw blade is sleeved on the periphery of the adapting sleeve; and the inside surface of the inner chuck and the inside surface of the outer chuck are respectively in tight contact with two lateral surfaces of the grinding wheel saw blade. Through the device, the residue of the saw blade with the outside diameter of phi 1,500 millimeters can be reused, and about 40 percent of using area can be increased in each saw blade, so that the purposes of saving resources and reducing the cost is fulfilled; and by using the adapting sleeve, the same grinding wheel saw blade is exchanged on the saws with different main shaft diameters, and application of the large-size grinding wheel saw blade in the different main shaft diameters of the saws is solved. The device has simple structure, and is good in saw blade clamping effect, convenient for disassembling and changing the saw blade.
Description
Technical field
The utility model relates to a kind of device of fixed emery wheel saw saw blade, belongs to the machining equipment technical field.
Background technology
In the bar machining processes; The indispensable rear portion finishing procedure in rolling bar line first road is sawing; Abrasive cutoff saw is the most frequently used sawing device of production line of bar because of its wide accommodation, sawing quality are high, and present most of special steel factory all is employed in and arranges on the cold bed runout table that abrasive cutoff saw carries out sawing to preliminary cooled bar; Some abrasive cutoff saws simultaneously or successively sawing satisfy the requirement of very fast rolling rhythm to improve cutting-rate.
On major diameter bar (φ is more than 130) production line, generally at φ 1500mm or more than the φ 1500mm, saw blade is an expendable part to the saw blade diameter of the abrasive cutoff saw of outfit aborning, and expense is higher, directly influences production cost.Saw blade after using at present still has bigger residual fraction, and therefore to reduce saw blade residual as far as possible, and the sawing amount that improves the saw blade monolithic is the main direction that reduces production costs to reduce the consumption of ton metal saw blade.Just need improve, so that saw blade is utilized present saw blade fixture for this reason.
The utility model content
The utility model technical problem to be solved provides a kind ofly can utilize the remaining saw blade of φ 1500 abrasive cutoff saws once more, improves the major diameter bar abrasive cutoff saw saw blade fixture that saw blade effectively utilizes area.
The technical scheme that solves the problems of the technologies described above is:
A kind of major diameter bar abrasive cutoff saw saw blade fixture; It comprises interior chuck, grinding wheel spindle axle sleeve, outer chuck, locking nut, and its improvements are that it has also increased adaptive cover; Adaptive cover endoporus cooperates with grinding wheel spindle axle sleeve external diameter; Adaptive cover external diameter cooperates with emery wheel saw blade endoporus, and adaptive cover is sleeved on the grinding wheel spindle axle sleeve, interior chuck and outside between the chuck; The emery wheel saw blade is sleeved on the adaptive cover periphery, and the medial surface of interior chuck closely contacts with the two sides of emery wheel saw blade respectively with the medial surface of outer chuck.
Above-mentioned major diameter bar abrasive cutoff saw saw blade fixture; The inboard card of the inboard card of chuck and outer chuck is being the annular concave surface around the chuck endoporus on every side in said; The thickness of adaptive cover is greater than the thickness of emery wheel saw blade, and the degree of depth sum of the annular concave surface of the inboard card of interior chuck and outer chuck is greater than the difference of adaptive cover thickness and emery wheel saw blade thickness.
The utility model interior chuck and outside increased adaptive cover between the chuck; Can the remaining saw blade (about φ 1100mm) of φ 1500mm external diameter saw blade be utilized on different saws once more; Every abrasive cutoff saw agreement that contracts a film or TV play to an actor or actress can increase the area that utilizes about 40%, has reached the purpose that economizes on resources, reduces cost; Simultaneously, the use of adaptive cover has realized that also the saw of the different main diameter of axle exchanges identical emery wheel saw blade, has solved the application of large scale emery wheel saw blade on the different saw main shaft diameters of axle.The utility model is simple in structure, and that saw blade clamps is respond well, be convenient to dismounting and change saw blade, fault rate is low, and maintenance capacity is little.

The specific embodiment
Show among the figure that the utility model is made up of interior chuck 1, grinding wheel spindle axle sleeve 2, adaptive cover 3, emery wheel saw blade 4, outer chuck 5, locking nut 6.
Emery wheel saw blade 4 be installed in abrasive cutoff saw gear-box 8 gearbox output shaft 9 stretch out shaft part.
Grinding wheel spindle axle sleeve 2 is positioned at chuck 1 outside, cooperates than the minor diameter place with gearbox output shaft 9, and grinding wheel spindle axle sleeve 2 axial location are in the transition shaft shoulder place of gearbox output shaft 9 big small axle diameters.
Show among the figure, select for use the adaptive cover 3 of various outer diameter that the emery wheel saw blade 4 of different-diameter can be installed.Adaptive cover 3 is an interference fits with grinding wheel spindle axle sleeve 2, is convenient to dismounting, only need change adaptive cover 3 when changing emery wheel saw blade 4, installs chuck, guarantees emery wheel saw blade 4 firm positions with knocking spanner locking nut 6.
