Abstract
The utility model discloses a concentric shaft fixture for processing ceramic carrier rollers. The concentric shaft fixture comprises a center shaft. A sleeve with inner diameter larger than outer diameter of the center shaft is sleeved on the center shaft. A check ring and an expansion sleeve having the outer diameter smaller than the inner diameter of a ceramic carrier roller are fitted to each end of a sleeve. Two conical nuts are screwed on the center shaft at the ends of the two expansion sleeves respectively. The taper of the nuts matches with that of conical holes of the expansion sleeves. After the concentric shaft fixture is clamped to a machine tool, coaxiality with a spindle of the machine tool can be guaranteed. Machining after rigid clamping and abutting of a ceramic tube is modified into machining after the inner wall of the ceramic tube is fastened by flexible expanding force of the inner-tapered expansion sleeves in the multi-slit structure formed by evenly arranged grooves, so that the defect that a workpiece is cracked by clamping can be overcome, and machining efficiency and machining precision of the workpiece can be increased. The concentric shaft fixture is simple and reasonable in structure, safe, reliable, convenient to manufacture, fast to mount, timesaving, material-saving, energy-saving, environment-friendly and suitable for being mounted on a common machine tool for machining and for machining of other tubes.
Description
Technical field
The utility model relates to the machine tooling jig, is specially adapted to common chuck and is difficult for the tubular workpiece jig that holds, hold, belongs to the machine tooling equipment technical field.
Background technology
It is very extensive that belt-conveying is used, and belt roller adopted steel material to make in the past, although have preferably intensity and toughness, cost of manufacture is high, and the roll body wearing and tearing are very fast, has a strong impact on carrying roller service life.Emerging pulley for belt conveyer extensively adopts the ceramic material carrying roller at present.Its roll body of carrier roller is tubular structure, the characteristics such as the tubular ceramic carrying roller has the hardness height, anti-wear performance is excellent, holistic cost is low, energy-conserving and environment-protective, thereby application prospect is very wide.But the rigidity owing to chuck when the machined of tubular ceramic roller holds and holds, thereby ceramic roller tracheal rupture phenomenon often occurs, and has both had potential safety hazard, has a strong impact on again yield rate.Thereby design a kind of easy, safe, practical earthenware machined jig, become problem demanding prompt solution.
The utility model content
The utility model provides a kind of concentric shafts jig of being convenient to processing ceramic carrying roller on lathe, the defective that exists to overcome prior art.
For realizing the utility model purpose, this concentric shafts jig of being convenient to the processing ceramic carrying roller comprises a central shaft, it is characterized in that suit one internal diameter is greater than the sleeve pipe of central shaft external diameter on the described central shaft, an external diameter is assembled respectively successively less than the back-up ring of carrier roller internal diameter and the external diameter ringfeder less than the carrier roller internal diameter in the sleeve pipe two ends, each spinning one tapered cup nut on the central shaft of two ringfeder ends, the tapering of the tapering of tapered cup nut and ringfeder bellmouth is complementary.
Described ringfeder centre bore is bellmouth, radially evenly offers groove on ringfeder, and the degree of depth of groove is at least 2/3 of ringfeder height.
The length of described sleeve pipe is 1/2～1/3 of carrier roller length.
The internal diameter of described back-up ring is greater than the external diameter of central shaft; Described tapered cup nut also is installed with locking nut outward.
The technological progress that the utility model is obtained: because the utility model jig of axially symmetric structure is installed in the axiality that can guarantee behind the lathe with machine tool chief axis, can hold having rigidity now, hold the machined of carrying out behind the earthenware and be improved to the machined of carrying out after fastening to the flexible expanding force of ceramic pipe fitting inner wall by the interior tapered nylon ringfeder that evenly offers the formed many crack structures of groove, not only so that the axiality of workpiece to be machined be guaranteed, the defective that also can effectively avoid workpiece to be split by card, can greatly improve working (machining) efficiency and the machining accuracy of workpiece, simple and reasonable, safe and reliable, easy to make, quick for installation, material-saving saves time, energy-conserving and environment-protective, not only be suitable for being installed on the machine tool earthenware is processed, also can be used for the processing of other tube-like piece.

The specific embodiment
As shown in Figure 1, this concentric shafts jig of being convenient to the processing ceramic carrying roller comprises that two ends are provided with externally threaded central shaft 2, this central shaft 2 is hollow shaft or solid shafting, at the sleeve pipe 5 of central shaft 2 suits one internal diameter greater than central shaft 2 external diameters, the length of sleeve pipe 5 is according to the length of carrier roller 6 and hold the position and decide, the length of sleeve pipe 5 preferably carrier roller 6 length 1/2～1/3, length according to carrier roller 6, the sleeve pipe 5 that plays the spacing effect can be with one or more, an external diameter is assembled respectively successively less than the back-up ring 4 of carrier roller 6 internal diameters and the external diameter ringfeder 3 less than carrier roller 6 internal diameters in the two ends of sleeve pipe 5, the internal diameter of back-up ring 4 is greater than the external diameter of central shaft 2, each spinning one tapered cup nut 1 on the central shaft 2 of two ringfeders, 3 ends, the outside of tapered cup nut 1 is spinning locking nut 7 also.
Such as Fig. 2, shown in Figure 3, ringfeder 3 preferably adopts nylon material to make, ringfeder 3 centre bores are bellmouth, the tapering of this bellmouth is identical with the tapering of tapered cup nut 1, radially on ringfeder 3, evenly offer multiple tracks groove 8, the degree of depth of this groove 8 is at least 2/3 of ringfeder 3 height, the groove 8 of offering makes ringfeder 3 first halves form many gap structures, when screwing both sides or either side conic 1, the male cone (strobilus masculinus) of conic 1 is pushed the inner conical surface of the ringfeder 3 that is complementary with its tapering, so that the inner peripheral surface of the radially swollen most outer circumference surface of ringfeder 3 and carrier roller 6 forms interference fit, thereby rely between the two frictional force to realize being fastenedly connected of 6 of the utility model and carrier rollers, then make machine chuck hold an end of the utility model central shaft 2, the top other end that holds central shaft 2 of tailstock tool, and then enforcement is to grinding or the machining of carrier roller 6.The tensioner link position that ringfeder 3 and carrier roller are 6 preferably leaves the nose end certain distance of carrier roller 6, to increase the resistanee to rupture of carrier roller 6 restraint locations.The conic 1 of outwarding winding, nylon ringfeder 3 self elastic shrinkage makes the reduced diameter of ringfeder 3, and the carrier roller 6 that processes can take off.
