Abstract
The invention belongs to a holding device used in part surface heat treatment, and especially used in surface quenching of a ball head part of an end of a shaft part. The invention specifically relates to a holding device used in part surface heat treatment. The device comprises a positioning shaft used for receiving a shaft part, and a fan closely matching the positioning shaft. With the cooperation of a fastening nut, a spring and a locking plate, the shaft part is firmly held. Gas flow is introduced from a blowing port, such that the fan rotates, and the positioning shaft and the shaft part rotate under the driving. The holding device provided by the invention is convenient to operate. With the device, various parameter requirements specified by a drawing of the part can be ensured, and the quenching hardness value and hardened layer depth of the surface of each part are substantially constant. Therefore, a problem that requirements of specified hardness value and hardened layer depth cannot be satisfied by surface quenching of a shaft part with ball heads on two ends can be solved. According to the invention, external gas flow is introduced as a power source, such that a manner of adopting a motor as the power source is avoided. Therefore, weight is reduced, energy source is saved, and cost is reduced.

Background technology
Bulb part surface as axial workpiece termination quenches, and part requires surface hardness HRC54-60, and the middle 2.5mm that is less than of bulb does not need quenching, critical surface hardness HV>475, hardening depth 1-2mm.Former quenching method is to carry out hard surfacing by the hand-held part of workman, be very easy to occur the uneven phenomenon of being heated, and then make the surface hardness of part termination inhomogeneous, and can not ensure hardening depth 1-2mm, often occur hardenability exceed 2mm even through hardening to part breaking.
Summary of the invention
Goal of the invention: provide a kind of and can solve the inhomogeneous problem of axial workpiece ball head point surface hardness for the heat treated clamping device of piece surface, ensure hardening depth.
Technical scheme: a kind of for the heat treated clamping device of piece surface, comprise locating shaft 4 for holding axial workpiece, with the close-fitting fan 8 of locating shaft 4, the position that fan guard 7 is corresponding with fan blade is provided with blowing mouth and air outlet, on locating shaft, be provided with outside screw, coordinate spring 1 and locking plate 3 that axial workpiece is held tightly by fitting nut 2, air-flow is introduced fan 8 is rotated from blowing mouth, and then drives locating shaft 4 and axial workpiece rotation.
Also be provided with bearing 5, bearing 5 is contained in bearing housing 6, and locating shaft 4 is inserted in bearing 5.
Locking plate 3 cross sections are trapezoidal, and the whole body is provided with three openings, realizes holding tightly axial workpiece by screwing fitting nut 2 extrusion springs 1.
On fan 8, be provided with fan locating sleeve 9, by closely cooperating of 9 realizations of fan locating sleeve and locating shaft 4.
Also be provided with fan cover plate 10, fixing with fan guard 7 by screw 11.
The outside surface of fitting nut 2 and locating shaft 4 carries out annular knurl processing.
Beneficial effect: the present invention is easy to operate, can ensure that part ensures the various parameter requests of drawing regulation, and hardness value and case depth that each piece surface quenches are basically identical, the hard surfacing that has solved axial workpiece two ends and be bulb shape cannot reach the requirement of regulation hardness value and case depth.Owing to having adopted the mode that outer gas stream is introduced as to propulsion source, avoid the mode of special use motor as propulsion source, alleviate weight on the one hand, save on the other hand the energy and reduced cost.Owing to having used and the close-fitting locating shaft of fan, on the one hand, can effectively not need heat treated part to hold axial workpiece, on the other hand, by the cooperation of fitting nut and locking plate, realization is effectively held tightly axial workpiece, thereby ensures heat treated homogeneity.

Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail, refers to Fig. 1 to Fig. 7.
A kind of for the heat treated clamping device of piece surface, comprise locating shaft 4 for holding axial workpiece, with the close-fitting fan 8 of locating shaft 4, the position that fan guard 7 is corresponding with fan blade is provided with blowing mouth and air outlet, on locating shaft, be provided with outside screw, coordinate spring 1 and locking plate 3 that axial workpiece is held tightly by fitting nut 2, air-flow is introduced fan 8 is rotated from blowing mouth, and then drives locating shaft 4 and axial workpiece rotation.
Also be provided with bearing 5, bearing 5 is contained in bearing housing 6, and locating shaft 4 is inserted in bearing 5.
Locking plate 3 cross sections are trapezoidal, and the whole body is provided with three openings, realizes holding tightly axial workpiece by screwing fitting nut 2 extrusion springs 1.
On fan 8, be provided with fan locating sleeve 9, by closely cooperating of 9 realizations of fan locating sleeve and locating shaft 4.
Also be provided with fan cover plate 10, fixing with fan guard 7 by screw 11.
The outside surface of fitting nut 2 and locating shaft 4 carries out annular knurl processing.
Fan 8 in wind, in the time that fan 8 rotates, driving locating shaft 4 to rotate, fitting nut 2 screws with the screw thread of locating shaft 4, three openings of the locking plate 3 in fitting nut 2 are opening closure in the time of rotation fitting nut 2, fitting nut 2 and axial workpiece, locating shaft 4 is combined as a whole, in the time that locating shaft 4 rotates, locating shaft 4 is driving axial workpiece rotation in bearing 5 together, bearing 5 is contained in bearing housing 6, spring 1 is housed in fitting nut 2, locking plate 3, make axial workpiece and fitting nut 2, locating shaft 3 plays the fastening effect that screws while being connected as a single entity, for ensureing safety, fan guard 7 is covered with fan, by 3 screws 11 of fan cover plate 10 use, fan guard is fastened as a whole.
When use, first, axial workpiece is put into locating shaft 4 endoporus, then, screw fitting nut 2, three openings opening closure in the time screwing fitting nut 2 of the locking plate 3 in fitting nut 2, now, locking plate 3 clamps axial workpiece, and axial workpiece is fixed in locating shaft 4.Wind is opened, wind passes through blast inlet by ozzle and is blowing fan 8, fan 8 is driving locating shaft 4, locating shaft 4 is driving axial workpiece to rotate in bearing 5, now, hand-held this surface hardening device, contacts 0.4 second by axial workpiece with ruhmkorff coil, after quenching-in water, axial workpiece is taken out in water immediately after axial workpiece being removed to ruhmkorff coil at once.Because fan 8 is being moved in wind, axial workpiece can at the uniform velocity rotate, Axle Surface quenching hardness can reach uniformity, and within case depth can be controlled at the scope of regulation, and in the middle of bulb, being less than 2.5mm region does not need to quench, critical hardness HV >=475, can ensure, this surface hardening device can ensure quality product requirement.Can complete hard surfacing process.
The present invention is easy to operate, can ensure that part ensures the various parameter requests of drawing regulation, and hardness value and case depth that each piece surface quenches are basically identical, the hard surfacing that has solved axial workpiece two ends and be bulb shape cannot reach the requirement of regulation hardness value and case depth.Owing to having adopted the mode that outer gas stream is introduced as to propulsion source, avoid the mode of special use motor as propulsion source, alleviate weight on the one hand, save on the other hand the energy and reduced cost.Owing to having used and the close-fitting locating shaft of fan, on the one hand, can effectively not need heat treated part to hold axial workpiece, on the other hand, by the cooperation of fitting nut and locking plate, realization is effectively held tightly axial workpiece, thereby ensures heat treated homogeneity.
