Abstract
The manual screw thread reaming plate with built-in centering chuck is composed of reaming plate body, curve disk, end cover, screw disk and claw, and the components of ratchet sleeve with built-in centering chuck and cutter-lifting mechanism, etc. it is a manual tool for processing external screw thread of pipeline and bar stock. The hinge plate body is a main body of the threaded hinge plate, is a hollow approximate cylinder, is provided with a square-tooth ratchet wheel, and is internally provided with claws, and three circular holes are uniformly distributed in the inner diameter direction of the ratchet wheel. In the ring groove of the hinge plate body, a wire holding disc and a centering chuck formed by claws are arranged, and the ratchet wheel is matched with the ratchet wheel sleeve and respectively axially positioned by a retainer ring. The pawl on the ratchet sleeve is engaged with the ratchet teeth to realize the directional rotation of the hinge plate body.
Description
The utility model relates to the manual hinge panel assembly that a kind of process pipeline, bar external screw thread are used.
The mantle fiber instrument that existing manual threading is used has following several: a kind of is simple in structure, the circular die of no centering measure, this device makes screw thread crooked adding man-hour easily, make the product that processes defective or of poor quality, workman's operation that therefore need be skilled in technique.Second kind is that screw thread hinge plate is joined special-purpose and the location processing of the akin sleeve of work piece outside dimension, like this, needs to be equipped with various different sizes, a considerable number of abutment sleeve, to use, very inconvenience of management.The third is to be provided with centering chuck in the outside of pipe threading plate, it can guarantee that machining screw is not crooked, but because centering chuck is installed in the ratchet sleeve outside, make this assembly axis to oversize, cause the volume of device to weigh greatly, especially can not processing length less than 150 millimeters whorl work piece, and processing tailing residue too much causes waste.
Task of the present utility model is, for overcoming the defective of said apparatus, provides that a kind of volume is little, rational in infrastructure, centering is respond well, easy to adjust, can processing work length cut with scissors plate, simultaneously greater than the screw thread more than 50 millimeters, the scope of application of screw thread hinge plate can be enlarged, material can be saved again.
Main points of the present utility model are, the centering chuck that will be installed in the ratchet sleeve outside omits, and utilize hinge plate body inner space, and radially interior along square tooth papillae wheel (is separated by 120 °) symmetrically and designed three circular holes, and be respectively charged into the claw of arc tooth.Claw constitutes the built-in centering chuck of screw thread hinge plate with the silk dish, by the sleeve of manual rotation silk dish outer face, can adjust the advance and retreat position of claw, to adapt to the whorl work piece of processing various different sizes within the specific limits.
The utility model is that the built-in centering chuck that hinge plate body, curve disc, end cap, ratchet sleeve, silk dish and claw are constituted has reached critical piece compositions such as cutter mechanism.
The hinge plate body is the approximate circle cylinder of a hollow, and an end face is useful on four square grooves that screw die is installed, and a cannelure and four screw holes at hinge plate body cylinder middle part, have the boss of a band circular hole, and circular hole and boss are used for having installed cutter mechanism.Boss nearby has side's dentation ratchet, radially is uniform-distribution with three circular holes at ratchet interior, interior dress claw, and the cannelure on three circular holes and the end face intersects, and claw is exceeded bottom this cannelure, so that mesh with the silk dish.The silk dish is packed into and is cut with scissors in the cannelure of plate body, makes axial location with a back-up ring.Ratchet cooperates with ratchet sleeve, and ratchet on the ratchet sleeve and square tooth papillae gear teeth meshing are rotated with the orientation that realizes the hinge plate body, and ratchet sleeve is made axial location with another back-up ring.
Curve disc is a circular disk body, one end face has the curve of 4 circular-arc projections, circumference has one section arc groove outward, be used for having installed cutter mechanism, curve disc is being cut with scissors on the plate body with end cap and 4 screw in compressions, and the cannelure on the hinge plate body is the activity space of 4 circular-arc projection curves on the curve disc, pulled cutter mechanism, curve disc is just rotated within the specific limits.
Ratchet sleeve is a loop configuration, and a side is equipped with ratchet and pulls thick stick, and the inner shock mount of ratchet resets, and pulling thick stick is to hold afterburning handle, and the square shaped teeth engagement on ratchet and the ratchet realizes cutting with scissors plate body and does directed the rotation.
Centering chuck is to be cooperated with the silk dish by three cylindrical claws to constitute, have equidistant arc tooth on the claw, silk dish one end face has equidistant snail line to be meshed with arc tooth on the claw, there is sleeve silk dish other end, hold the sleeve rotation, three claws just can be advanced and retreat, to adapt to the workpiece of processing various outer diameter, the inner face of three claws rubs mutually with the outer surface of workpiece when the work of hinge plate, to play to screw die centering effect.
Screw thread hinge plate after the improvement has following advantage:
1, effectively utilizes the locus in the ratchet on the hinge plate body, saved an optional feature, the axial dimension of this device is significantly reduced, realized to process the whorl work piece of shorter size, enlarged the scope of application of screw thread hinge plate.
2, because reasonable in design, it is respond well to feel relieved, and the user is not required too high operating technology level.
3, because the volume of hinge plate reduces, in light weight, easy to use, saving material is convenient to packed and transported.
