Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Shown in composition graphs 1, the part processing supporting tool of spherical end, comprise at least two pieces of briquettings, described briquetting can fit together formation entirety, each briquetting is provided with groove for the position of fitting, groove on the as a whole rear each briquetting of briquetting laminating can surround a spherical support chamber jointly, and the common seam crossing of each briquetting is provided with and is communicated with spherical support chamber and extraneous through hole 31.Wherein, the quantity of briquetting is more than two pieces, and Fig. 1 is two pieces; It can be plane that each briquetting is used for binding face, also can be curved surface or other irregular, stick together mutually as long as each briquetting can coordinate; The spherical support chamber that groove surrounds jointly, for placing the ball-shaped end of the part of spherical end, can arrange elastic insert usually to be suitable for being fixed the ball-shaped end of different-diameter on the inner surface in spherical support chamber; Through hole 31 passes for the bar portion of the part of spherical end, and its degree of depth can carry out relative set according to the length in the bar portion of the part of spherical end, is generally less than the length in the most quarter butt portion of the part of the spherical end equaling to be supported.

Preferably, more as shown in Figure 1, the quantity of described briquetting is two pieces, is respectively left briquetting 1 and right briquetting 2; The groove that described left briquetting 1 and right briquetting 2 are arranged be the corresponding binding face of left briquetting 1 and right briquetting 2 is arranged separately one in hemispheric brace groove (11; 21), left briquetting 1 and right briquetting 2 are fitted latter two brace groove (11; 21) jointly surround described spherical support chamber, described through hole 31 is arranged on the seam crossing that left briquetting 1 and right briquetting 2 fit.Left briquetting 1 and the corresponding binding face of right briquetting 2 can be planes, also can be curved surface or other irregular, stick together mutually as long as the binding face of left briquetting 1 can coordinate with the binding face of right briquetting 2.

Conveniently the bar portion of the part of spherical end is passed, and described through hole 31 is greater than the round taper hole in inside end aperture for outer end aperture.

On the basis of the above, in order to ensure the support effect of the part to spherical end, as shown in Figure 2, this supporting tool also comprises the locating wedge 32 for embedding in through hole 31.During excesssive gap between the diameter of through hole 31 and the bar portion of the part of spherical end, locating wedge 32 can be embedded makes the bar portion of the part of spherical end be completely fixed in this gap, be more conducive to the smooth processing of the part of spherical end, further increase the accuracy of processing.Locating wedge 32 can adopt multiple material to make, and preferably adopts elastomeric material to make; The locating wedge 32 that elastomeric material is made, be that contact soft with part can not damage its surface on the one hand, it is larger that another aspect rubber material has elasticity adjustable extent.

Preferably, the quantity of described locating wedge 32 is two.Described locating wedge 32 is half taper type structure, and its inner surface has the groove of semicircular arc, outer surface is the half cone-shaped curved surface matched with through hole 31; Locating wedge 32 inner surface of this structure can match with the bar portion of the part of spherical end, and its outer surface can coordinate with through hole 31; Two locating wedges 32 use simultaneously, and the bar portion of the part of spherical end can be made coaxial with through hole 31, and the accuracy of processing is better.

As another preferred version of the present utility model, as shown in Figure 3, this supporting tool also comprises the clamping device 4 for clamping left briquetting 1 and right briquetting 2.Concrete, described clamping device 4 is bench vice.

Support process: left hand holds left briquetting 1, embeds in the brace groove 11 of left briquetting 1 by the ball-shaped end of part; The right hand holds right briquetting 2, is fitted by right briquetting 2, the ball-shaped end exposed parts of part is embedded in the brace groove 21 of right briquetting 2 with left briquetting 1, makes the bar portion of the part of spherical end through through hole 31 simultaneously; Then, check whether two pieces of briquettings comprise the ball-shaped end of part completely; Hand-heldly fix left briquetting 1 and right briquetting 2, the left briquetting 1 after laminating and right briquetting 2 are put on the clamp port of clamping device 4, clamping.
