Abstract
The utility model relates to a hand-operated reamer comprising a ratchet spanner, a reamer body and a driving plate. The hand-operated reamer is characterized in that the driving plate is provided with locating columns at two ends and a spiral hole in the middle, the spiral hole is in threaded connection with a spiral feeding rod, the lower end of the spiral feeding rod is provided with a locating pin hole, and the upper end of the spiral feeding rod is provided with a hexagonal head; the lower end of the reamer body is provided with a tool rest with a reamer, the upper end of the reamer body is provided with a locating pin slot, and the tool rest is fastened at the lower end of the reamer body by using a screw; and the hexagonal head of the spiral feeding rod is inserted into an inner hexagonal head of the ratchet spanner and sleeved and connected with the inner hexagonal head of the ratchet spanner. The hand-operated reamer is simple in structure, easy to manufacture, low in cost and convenient to assemble and use; when hand-operated reaming operation is carried out by using the ratchet spanner, the amount of feed is easy to control, the reamer body has a self-centering function, and the hand-operated reaming concentricity is high; and when the hand-operated reaming operation is carried out in a small space, the reaming operation can be finished in the small space by only replacing a long spiral feeding rod.
Description
Technical field
The utility model relates to a kind of cutter, is specifically related to a kind of hand-operated reamer.
Background technology
The machining box-type part, part and part do not only depend on screw-driving, also need equipped close-fitting pin to be used for torsion pass.Because box parts is very large, the position degree of pin-and-hole is required very high, require equipment precision high, add the man-hour part and be out of shape easily, cause the dislocation of hole in piece part, pin can't be packed in the pin-and-hole.This processing mode, long processing time, expense height, qualification rate is low.Less for the dislocation hole, can adopt the method in manual reamer align reaming hole to make the position degree in hole reach requirement, it is long to repair the strand time, and the hole is larger for misplacing, and can't repair by hand strand, and part can only be scrapped.Adopt machine maintenance to join strand, owing to volume of part is large, complex structure, part is out of shape easily and produces interference when clamping, and the machine maintenance qualification rate is still very low.
Summary of the invention
The purpose of this utility model is the shortcoming that will overcome above-mentioned technology, provides a kind of simple in structure, convenient mounting and clamping, positioning accuracy is high, the fraising time is short, the hand-operated reamer of good reliability.
Hand-operated reamer of the present utility model, comprise ratchet spanner, cutter hub and driver plate, it is characterized in that: described driver plate two ends are provided with locating dowel, and the centre is provided with threaded hole, the screwfeed bar that has been threaded in the threaded hole, the lower end of screwfeed bar is provided with dowel hole, the upper end is provided with six square toes; Described cutter hub lower end is provided with the knife rest with reamer, and the upper end is provided with the location cotter way, and knife rest is fixed tightly in the lower end of cutter hub by screw; Socket connects in interior six square toes of the six square toes insertion ratchet spanner of screwfeed bar.
Hand-operated reamer of the present utility model, simple in structure, manufacturing expense is low, the assembling easy to use; By the operation of ratchet spanner Manual reaming, the depth of cut is controlled easily, and cutter hub has the self centering function, and the concentricity of Manual reaming is high; Carry out the Manual reaming operation at small space and only need use long screwfeed bar instead, just can finish the fraising operation of small space.
