Abstract
The utility model discloses a surface quenching tool for holding and clamping a slender-axle type workpiece. The tool comprises a vertical big screw hole and a vertical small screw hole which are respectively arranged in the upper portion and the lower portion of a tool main body in coaxial mode. A horizontal through hole is perpendicular to two sides of the big screw hole and horizontally communicated with the big screw hole. The axes of the three screw holes are arranged on the same plane. The surface quenching tooling is the equivalent of an upper core clamper. The workpiece is heated and elongated so that an upper axle journal of the workpiece is in line contact with an inner hole of the surface quenching tool in a small range and relatively slides in the vertical direction and the workpiece can elongate in relatively free mode in the process of surface quenching. Therefore, the probability of deformation is decreased, straightening cost is reduced, and risks of fractures due to straightening are avoided.
Description
Technical field
The utility model belongs to the Machining Technology field, relates to the be installed frock of usefulness of a kind of thin and long shafts spare hard surfacing.
Background technology
Existing thin and long shafts spare is in the hard surfacing process; Usually fix workpiece in the top up and down center hole up and down that withstands on workpiece that adopts quenching machine; Like this in quenching process; Because Workpiece length direction size increases, aggravation is out of shape in top in addition fixedly making workpiece can't extend in the longitudinal direction and cause, and then has strengthened the aligned cost.In the production, the slender piece of diameter below 25mm, usually because quenching strain is too big, can't alignment and scrap.
Summary of the invention
The purpose of the utility model provides the be installed frock of usefulness of a kind of thin and long shafts spare hard surfacing, and when solving the thin and long shafts spare hard surfacing that the existing mode of being installed brings, workpiece can't extend and causes being out of shape too big problem at length direction.
The technical scheme that the utility model adopts is; The be installed frock of usefulness of a kind of thin and long shafts spare hard surfacing; The vertically big screw and the vertical little screw of coaxial setting about being included in the frock main body; Be linked with horizontal through hole perpendicular to vertically big screw both sides level, three above-mentioned screw axis are distributed on the plane.
The beneficial effect of the utility model is, is the special tooling that the hard surfacing of thin and long shafts spare is installed, and solved effectively in the existing mode that is installed, and the problem that the workpiece quenching strain is too big has reduced the aligned cost, avoided the risk of alignment fracture.
Description of drawings
Fig. 1 is the utility model hard surfacing tool structure synoptic diagram;
Fig. 2 is the thin and long shafts spare hard surfacing frock view that is installed.
Among the figure, 1. go up top, 2. screw, 3. frock main body (being that Fig. 1 is whole), 4. workpiece, 5. time top, 6. vertically big screw, 7. horizontal through hole, 8. vertical little screw.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
Fig. 1 is the thin and long shafts spare hard surfacing tool structure of the utility model; The vertically big screw 6 and vertical little screw 8 of coaxial setting about being included in the columniform frock main body 3; (be a step cover with three screws; Put three screws), vertically big screw 6 both sides levels are linked with horizontal through hole 7, and three above-mentioned screw axis are distributed on the plane.The external diameter of frock main body 3 is φ C, and the internal diameter of vertically big screw 6 is φ A, and the internal diameter of vertical little screw 8 is φ B.
Fig. 2 carries out the synoptic diagram that the slender axles hard surfacing is installed for the frock of using the utility model.Be used for being enclosed within the vertically big screw 6 equipment among Fig. 2 last top 1 on; 2 pairs of tops of screw through horizontal through hole 7 (M10) be fixed on equipment last top 1 on; Reach the effect of fixedly quenching frock 3, vertical little screw 8 (φ B) is used for being enclosed within the last axle journal of the workpiece 4 of slender axles.Wherein φ A and last top 1 radius clearance are about 0.5mm, and the radius clearance of axle journal is about 1mm on φ B and the slender axles workpiece 4.
Among Fig. 2, workpiece 4 be installed main lean in the frock main body 3 φ B hole with top 5 realize down.The last axle journal of workpiece 4 inserts in the hole of φ B, and following top 5 withstand in the following center hole of workpiece 4, so that realize card engaging workpiece 4; The rotation of workpiece 4 is mainly by top 5 driving down.
The existing mode that is installed is passed through top fixation workpiece 4 up and down, owing to quench when heating, workpiece 4 must extend; Because workpiece 4 receives top restriction and can't extend, and will inevitably produce bending, to rotate when workpiece 4 quenches in addition; Under action of centrifugal force, distortion is further amplified.The utility model quenching frock 3 is equivalent to top 1 effect; Workpiece 4 receives thermal elongation; Make on the workpiece 4 axle journal local with quenching frock 3 in φ B endoporus contact at line more among a small circle; And on vertical direction relatively sliding, workpiece 4 is reached relatively freely when hard surfacing extends, thereby reach the purpose that reduces to be out of shape.
During operation; Be fixed on frock main body 3 on top 1 earlier, following top 5 of quenching machine withstands in the following center hole of workpiece 4, moves down on the quenching machine top 1; Make that axle journal extend in the φ B hole of frock main body 3 on the workpiece 4; Reach the purpose of card engaging workpiece 4, during quenching, top 5 rotation drives under the quenching machine are mainly leaned in the rotation of workpiece 4.During quenching, the last axle journal of workpiece 4 relatively freely stretches in the φ of frock main body 3 B hole, reaches the purpose that reduces quenching strain.
The utility model is simple in structure, and is easy to operate, and reduced the distortion of workpiece widely, reduced the alignment cost, avoided the risk of alignment fracture.
