Abstract
The utility model provides a coaxial positioner, which comprises a mandrel. The coaxial positioner is characterized in that movable bushings which are connected with bearing supports are arranged on the outer sides of both ends of the mandrel, and tensioning holders and propping holders, which are provided with adjusting screws, are arranged on the inner sides of both ends of the mandrel in a staggered way. The structure of the positioner is simplified, the production cost is reduced, the production difficulty is decreased, the space occupied by the positioner is reduced, moreover, the positioner is convenient to mount and dismount, and in particular, the maintenance and repair of the positioner are simple and convenient, and time and labor can be saved. According to the positioner, the defects of the prior art caused by the complex structure, such as large size, inconvenient mounting and dismounting and low working efficiency can be effectively overcome, and thereby the positioner is reliable to use and convenient to repair, and is low-cost.
Description
Technical field
The utility model relates to a kind of positioning device, especially a kind of coaxial positioning apparatus of convenient mounting or dismounting.
Background technique
The mass transport of use on large-scale maintenance machinery exists disadvantage with the positioning device of driving shaft bearing bearing hole at present: the one, and complex structure, volume is big, needs complicated multiple location just can reach the assembly precision requirement.The 2nd, quite inconvenience of assembling and dismounting, inefficiency.Therefore, be necessary existing technology is improved.
Summary of the invention
For overcoming the complex structure that existing positioning device exists, volume is big, assembling and dismounting inconvenience, and deficiencies such as inefficiency, it is a kind of simple in structure that the utility model provides, and Location accuracy is high, simple load and unload coaxial positioning apparatus.
The utility model is accomplished through following technical proposal: a kind of coaxial positioning apparatus; Comprise mandrel; It is characterized in that the outside, mandrel two ends is provided with movable axle sleeve; The inboard be crisscross arranged band adjusting element on it the tension seat with shore seat so that through the tension seat with shore seat with and on adjusting element make movable axle sleeve and the bearing spider that is attached thereto is accomplished the location along moving in the mandrel, move outward and accomplish dismounting.
Said movable axis cover is made as that outside diameter is big, and the step type axle sleeve that inside diameter is little is interval with through hole on the axle sleeve, and bearing spider is placed in the little inboard of diameter of movable axle sleeve, realizes both concentric locating.
Said tension seat with shore seat and be crisscross arranged along the mandrel radial surface, wherein, the tension seat is provided with through hole; This through hole is communicated with the through hole that movable axis puts, and first adjusting element places the through hole of connection, so that during fastening first adjusting element; Make movable axle sleeve along moving in the mandrel, realize coaxial positioning; Shore seat and be provided with through hole, second adjusting element places in this through hole, so that during fastening second adjusting element, movable axle sleeve is pushed up outside mandrel, realizes dismounting.
Said tension seat with shore seat and be evenly distributed on the same section of mandrel, perhaps be evenly distributed on the different section of mandrel, so that the inside and outside of realization activity axle sleeve moved.
Said tension seat with shore seat and be provided with two of symmetry at least along the mandrel radial surface so that make movable axle sleeve move or move in equably outward.
Said first adjusting element is for regulating bolt;
Said second adjusting element is an adjusting screw rod.
The utility model compared with prior art has advantage and effect: adopt such scheme; Not only simplify the structure of positioning device, reduce manufacture cost and manufacture difficulty, dwindled the positioning device occupation space; But also bring convenience to mounting or dismounting; When especially positioning device being carried out M R, simple and convenient, save time and laborsaving; Effectively overcome existing technology because of bulky, assembling and deficiencies such as dismounting inconvenience, inefficiency that complex structure brings, made it to use reliably, easy to maintenance, cost is low; This device is applicable to the machinery that needs the location.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be further described.
Like Fig. 1 and 2; The coaxial positioning apparatus that the utility model provides; Comprise mandrel 1, the said mandrel 1 two ends outsides is provided with the movable axle sleeve 3 that links to each other with bearing spider 5, and the inboard is crisscross arranged, and it is gone up the tension seat 2 of band adjusting element and shores 6; So that through tension seat 2 with shore seat 6 with and on adjusting element 4 and 7 make movable axle sleeve 3 and the bearing spider 5 that is attached thereto is accomplished coaxial positioning along moving in the mandrel 1, move outward and accomplish dismounting; Movable axle sleeve 3 is made as that outside diameter is big, and the step type axle sleeve that inside diameter is little is established through hole on the axle sleeve at interval, and bearing spider 5 is placed in the little inboard of diameter of movable axle sleeve 3, realizes both concentric locating; Said tension seat 2 with shore seat 6 and be crisscross arranged along mandrel 1 radial surface; Wherein, tension seat 2 is provided with through hole, and this through hole is communicated with through hole on the movable axle sleeve 3; First adjusting element---bolt 4 places the through hole of connection; So that during fastening adjustment bolt 4, make movable axle sleeve 3 along moving in the mandrel 1, realize coaxial positioning; Shore seat and 6 be provided with through hole, second adjusting element---screw rod 7 places in this through hole, so that during fastening adjustment screw rod 7, movable axle sleeve 3 push up along mandrel 1 outside, and realization is dismantled; Said tension seat 2 with shore seat 6 and be evenly distributed on the same section of mandrel 1 so that the inside and outside of realization activity axle sleeve 3 moved; Said tension seat 2 with shore seat 6 and be provided with three of symmetry along mandrel 1 radial surface so that make movable axle sleeve 3 move or move in equably outward.
When needing the assembling coaxial positioning apparatus,, make movable axle sleeve 3 inwardly move to desired location, drive the rigging position that moves to setting in the bearing spider 5, realize coaxial positioning along mandrel 1 both sides through fastening adjustment bolt 2; During dismounting,, movable axle sleeve 3 is moved to outside both sides along mandrel 1 break away from oriented bearing spider 5, realize that the dismounting of positioning device breaks away from through fastening adjustment screw rod 7.
