Background technique
At present, in mechanical processing industry and other manufacturings, metal or nonmetal component have progressively adopted standard tool or accessory etc. to raise the efficiency at aspects such as machining, measurement, assemblings, and in the process of employing standard tool and accessory, some metals or nonmetal component are about needing accurate location on Kong Yu tool or accessory, to guarantee the precision of the aspects such as processing, measurement, assembling, this has become the important embodiment of one of the ability aspects such as modern processing, measurement, assembling.Existing such tool or accessory are about accurately main straight pin or the taper pin of adopting in location of the hole on component, although can solve to a certain extent the problem of the aspects such as the processing, measurement, assembling of such part, but still exist location inaccurate for high-precision component, thereby the error that causes the aspects such as processing, measurement, assembling, finally makes product occur quality problems.
Related documents also discloses some elastic tensioning devices, its principle is to utilize air pressure or the motion of hydraulic drive pull bar, the inner bulging device being connected with pull bar makes the distortion of elasticity inner expanding sleeve become large by the conical surface, to play the effect of tensioner location, but majority is automation tool or accessory for producing in batches, and complex structure, expensive, must be furnished with relevant equipment could move simultaneously, and production environment etc. is had relatively high expectations.
Summary of the invention
The purpose of this utility model is exactly that a kind of simple to operate, cost is low, using scope is wide elasticity inner bulging device is provided in order to overcome the defect that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions: a kind of elasticity inner bulging device, be mainly used in machining, measure, on assembly fixture or accessory, metal or non-metallic component are accurately located about hole, it is characterized in that, this elastic tensioning device comprises elasticity inner expanding sleeve, tensioner nut, sphere tensioner screw, ball, described elasticity inner expanding sleeve endoporus is tapped hole, and tapped hole bottom and aperture are the conical surface, and cut quartering groove at two ends, described ball pack in elasticity inner expanding sleeve with elasticity inner expanding sleeve bottom the conical surface contact, described sphere tensioner screw is connected with elasticity inner expanding sleeve by screw thread, the sphere of sphere tensioner screw contacts with ball, described tensioner nut is connected with elasticity inner expanding sleeve by screw thread, and fit with the inner expanding sleeve top conical surface.
Described ball diameter is less than elasticity inner expanding sleeve interior threaded hole, packs in its hole, and contact with its bottom conical surface by elasticity inner expanding sleeve one end.
Described sphere tensioner screw is by screwing in elasticity inner expanding sleeve tapped hole, and its sphere one end contacts with ball.
Described tensioner nut is cone-shaped, is connected with inner expanding sleeve internal thread by outside thread, and the tensioner nut conical surface and the laminating of the elasticity inner expanding sleeve top conical surface.
Compared with prior art, the utlity model has following advantage:

Two, using scope is wide: this elasticity inner bulging device applicable to various metals or nonmetal component about needing accurate location on Kong Yu tool or accessory, to guarantee the precision of the aspects such as processing, measurement, assembling.
Three, simple to operate: only need to be arranged on and need the position supported according to part process requirements, install part locking, need not professional training etc.
Four, cost-saving: this apparatus structure is simple, be easy to manufacture, and interchangeability is strong.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic diagram before use of the present utility model;
Schematic diagram when Fig. 3 is of the present utility model use.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As shown in Figure 1, a kind of elasticity inner bulging device, be mainly used on the tools such as machining, measurement, assembling or accessory metal or non-metallic component and accurately locate about hole, this elastic tensioning device comprises elasticity inner expanding sleeve 2, ball 4, sphere tensioner screw 3 and tensioner nut 1.
Elasticity inner expanding sleeve 2 endoporus are tapped hole, and quartering groove has been cut at two ends, thread bottom is processed with the conical surface, and be also processed with the conical surface in screw mouth port part, the diameter of ball 4 is owing to being less than the bottom outlet of inner expanding sleeve tapped hole, so ball 4 packs into from the direction of the inner expanding sleeve 2 port conical surfaces, the outer-diameter threads of sphere tensioner screw 3 and the inner hole thread of inner expanding sleeve 2 are in the same size, and one end of sphere tensioner screw 3 is inner hexagonal hole, the other end is sphere, this sphere size is consistent with the diameter of ball 4, so sphere tensioner screw 3 uses inner hexagon spanner by being threaded in elasticity inner expanding sleeve 2, and sphere is fitted with ball 4 and ball 4 is contacted with the conical surface of inner expanding sleeve 2 tapped hole ends, the outer-diameter threads of tensioner nut 1 is same and inner expanding sleeve inner hole thread is in the same size, so tensioner nut 1 is connected with inner expanding sleeve 2 internal threads by outside thread, and tensioner nut 1 conical surface and inner expanding sleeve 2 conical surface laminatings.
As shown in Figure 2, when above-mentioned elastic device uses, first with inner hexagon spanner, tensioner nut is screwed out, inner expanding sleeve is put into the tool identical with its external diameter or accessory, adjust height, then use inner hexagon spanner to screw sphere tensioner screw, under sphere tensioner screw, depress, because inner expanding sleeve has cut quartering groove, the ball effect conical surface makes elasticity inner expanding sleeve spreading, makes it to be connected and fixed with tool.
As shown in Figure 3, in the time of securing part part, component are placed on tool or accessory by positioning hole, then use inner hexagon spanner to screw tensioner nut, the tensioner nut conical surface acts on the elasticity inner expanding sleeve conical surface, makes it distortion, thereby tensioner component, reach pinpoint object.
The utility model elasticity inner expanding sleeve adopts the spring steel of high-quality, and heat-treats, and makes it to have good elasticity.Secondly, inner expanding sleeve cylindrical is through the tight grinding of grinding machine, and surface has very high degree of finish, is can not have damage to workpiece hole surface thereby make at positioning metal or non-metal workpiece.Its operation is all used the inner hexagon spanner of standard, and universal strong is simple to operate.
