Abstract
The utility model discloses a gap-less pin shaft used for an artificial diamond hexahedral anvil press to be connected with a hinge beam, which forms a tapered composite structure. The utility model is composed of an outer pin shaft, an inner pin shaft a screw bolt, a blocking plate, etc., wherein, the outer pin shaft is provided with an inner hole having a certain conicity; the inner pin shaft has a certain conicity, which is corresponding to the conicity of the inner hole of the outer pin shaft. At least four paths of slits are arranged on the outer pin shaft, and the slits are inversely interactive. The utility model can eliminate the shaking phenomena of a compressor in the working process, and is favorable for enhancing the quality of the artificial diamond and convenient to disassemble. The utility model can be applied to the diamond compressor and the connection of other mechanical components.
Description
The utility model relates to a kind of axle, connects the bearing pin of usefulness especially for diamond cubic hinge press hinge beam.
The bearing pin that uses on the diamond press is the garden pin at present, in application, mainly contain following problem: first, because the connection request precision height between the hinge beam, when machining accuracy can not fully guarantee, for bearing pin can be packed in the hinge beam earrings hole, solve in the general gap that enlarges between axle and the hole of adopting, and it is spacious moving to cause the hinge beam to produce at the press duration of work, be commonly referred to as " breathing " phenomenon, thereby influence the diamond crystal growth; The second, when being subjected to especially big pressure between hinge beam earrings and the bearing pin, can produce plastic deformation, make very difficult that the dismounting of bearing pin becomes.
The purpose of this utility model is to provide a kind of zero-clearance bearing pin, eliminates spacious moving phenomenon, makes the disassemble or assemble of bearing pin convenient and easy.
The purpose of this utility model is achieved through the following technical solutions: the tapered composite structure of man-made diamond pressing machine hinge beam zero-clearance bearing pin, mainly form by the interior bearing pin in outer bearing pin and its endoporus of can packing into and plate washer and bolt, the endoporus of outer bearing pin and the external diameter of interior bearing pin have the tapering that cooperatively interacts, the little end of the diameter of axle of the promptly interior bearing pin of bearing pin one end is added with a plate washer outside, penetrate a bolt in the plate washer and link to each other with interior bearing pin, and with bolt that inside and outside bearing pin is fastening.
Cause on the bearing pin outside and have 4 mutual anyway road troughs less, to increase its radial-telescopic, the best is eight road troughs.
The utility model has the advantages that: owing to adopt the inside and outside axle construction that has tapering, in tightening during bearing pin, the external diameter of outer bearing pin is magnified, make it produce interference, thereby eliminate spacious moving phenomenon, get interior bearing pin during dismounting earlier, eliminate radial interference, outer pin diameter is diminished, form the gap, eliminated the dismounting difficulty that plastic deformation causes.
Fig. 1 is the sectional drawing of this bearing pin;
Fig. 2 is the structural representation that this bearing pin is connected with the hinge beam.
The endoporus of Fig. 1 China and foreign countries' bearing pins (1) has the tapering that matches with interior bearing pin (2), outer bearing pin is a Cylinder that has the certain taper endoporus, arbitrary end of bearing pin is established boss (5) outside as required, cause on the bearing pin outside and have four mutual anyway troughs less, each trough does not all connect fully when fluting, an end of bearing pin stays one section outside, so that outer bearing pin is an integral body, quantity the best of trough is eight; Interior bearing pin is a garden frustum, and an end little at diameter can connect fastening piece, as bolt (4).Plate washer can pass screw rod in (3).
Bearing pin penetrates in the earrings hole of man-made diamond pressing machine hinge beam (6) among Fig. 2, and the hinge beam is connected together.
Claims (3)
1, the zero-clearance bearing pin that connects usefulness between a kind of synthetic diamond cubic hinge press hinge beam, adopted the cone composite structure, it is characterized in that: form by an interior bearing pin (2) that has certain taper that has the outer bearing pin (1) of certain taper endoporus and match, cause on the outer bearing pin (1) and have the mutual anyway trough in four roads less with outer bearing pin hole taper.
2, bearing pin according to claim 1 is characterized in that trough the best mutual anyway on the outer bearing pin (1) is eight roads.
3, bearing pin according to claim 1 is characterized in that an end of outer bearing pin (1) is provided with boss, and the end that interior bearing pin (2) diameter of axle is little can connect fastening piece.
