Abstract
The utility model relates to an automobile transmission gear shaft quenching tool. The automobile transmission gear shaft quenching tool comprises a soleplate, a middle plate and a top plate, wherein the soleplate, the middle plate and the top plate are respectively provided with a positioning hole, the soleplate is provided with a support, the middle plate is arranged on the middle part of the support, an automobile transmission gear shaft is inserted into the positioning holes of the soleplate and the middle plate, since the diameter of each of a first stop plate and a second stop plate is greater than that of the positioning hole, the second stop plate of the automobile transmission gear shaft 1 presses the middle plate, the automobile transmission gear shaft is arranged in the positioning hole and hung on the middle plate, the positioning hole of the top plate is sleeved on the automobile transmission gear shaft and presses the first stop plate, so that the automobile transmission gear shaft is uniformly subjected to the straightening force from the positioning holes in the quenching process, a plurality of automobile transmission gear shafts are simultaneously inserted into a plurality of positioning holes in the quenching process, the straightening force is vast, and the automobile transmission gear shaft is not deformed.
Description
Technical field
The utility model relates to automobile component fixture for heat treatment, particularly automobile gearbox gear axle quenching frock.
Background technology
In manufacturing automobile gearbox gear axle process, thermal treatment is necessary operation.For improving the surface abrasion resistance, fatigue strength etc. of automobile gearbox gear axle, quenching is one requisite operation, yet because automobile gearbox gear shaft length is longer, during quenching, easily produce flexural deformation, and because main drive shaft diameter is conventionally larger, the in the situation that of whole through hardening, need highlyer than the temperature of normal quenching, therefore more easily cause the distortion of automobile gearbox gear axle, make it not reach due precision.
Utility model content
For the problems referred to above, the utility model provides automobile gearbox gear axle quenching frock, and when quenching, it,, to three sections of location of automobile gearbox gear axle, avoids it to deform, and simple in structure, easily assembling.
The technical scheme that the utility model is taked is:
Automobile gearbox gear axle quenching frock, comprise base plate, middle plate and top board, base plate, middle plate and top board are provided with pilot hole, base plate is provided with support, middle plate is positioned at the middle part of support, automobile gearbox gear axle is inserted in the pilot hole of base plate and middle plate, and the second stop plate of automobile gearbox gear axle is pressed on middle plate, and top board is pressed on the first stop plate.
For convenience of middle plate and top board are fixed on support, described support is 4, and middle plate and top board are provided with 4 bracket holes.
For making automobile gearbox gear axle bear uniformly the corrective force from base plate, middle plate and top board in quenching process, described middle plate is fixed on 1/2nd places that position on support is positioned at automobile gearbox gear shaft length.
For making automobile gearbox gear axle bear uniformly the corrective force from base plate, middle plate and top board in quenching process, simultaneously for avoiding automobile gearbox gear axle easily to take off after quenching, on described base plate, middle plate and top board, the diameter of pilot hole is less than the diameter of the first stop plate and the second stop plate, and than the large 2mm of the diameter of automobile gearbox gear axle.
Because the utility model carries out three sections of location to automobile gearbox gear axle, in quenching process, the corrective force of base plate, middle plate and top board avoids it to deform, after quenching, be convenient to again take off from this frock, and its simple in structure, easily operation, greatly facilitate quenching process, fully guaranteed Product Precision.
Accompanying drawing explanation
Fig. 1 is the structural representation of automobile gearbox gear axle.
Fig. 2 is that the utility model automobile gearbox gear axle quenching frock is used view.
Fig. 3 is the top board schematic diagram of the utility model automobile gearbox gear axle quenching frock.
Embodiment
Below in conjunction with specific embodiment, the utility model is further described, in illustrative examples and the explanation of this utility model, is used for explaining the utility model, but not as to restriction of the present utility model.
As shown in Figure 1, automobile gearbox gear axle 1 consists of stick-like body and the first stop plate 11 and the second stop plate 12 that are positioned on body, the effect of the first stop plate 11 is to be convenient to automobile gearbox gear axle sleeve be connected on gear box casing and prevent that the position relationship generation axial float between the two, the effect of the second stop plate 12 from being that the position of fix either ratio gear avoids it at automobile gearbox gear axle generation axial float.Because the diameter of stop plate is greater than the diameter of automobile gearbox gear axle body, and between the first stop plate 11 and the second stop plate 12, have suitable distance, applicant utilizes this natural character of these parts to correct to avoid these parts to invent automobile gearbox gear axle quenching frock of the present utility model in quenching process generation deformation in conjunction with multipoint positioning.
As shown in Figures 2 and 3, automobile gearbox gear axle quenching frock of the present utility model comprises base plate 4, middle plate 2 and top board 3, base plate 4, middle plate 2 and top board 3 are provided with pilot hole 32, base plate 4 is provided with support 5, middle plate 2 is positioned at the middle part of support 5, automobile gearbox gear axle 1 is inserted in the pilot hole 32 of base plate 4 and middle plate 2, because the diameter of the first stop plate 11 and the second stop plate 12 is greater than the diameter of pilot hole 32, therefore the second stop plate 12 of automobile gearbox gear axle 1 is pressed on middle plate, make automobile gearbox gear axle 1 be positioned at pilot hole 32, and hang on plate, the pilot hole 32 of top board is enclosed within on automobile gearbox gear axle 1, and be pressed on the first stop plate, thereby make automobile gearbox gear axle 1 in quenching process, evenly be subject to the corrective force from pilot hole 32, and many automobile gearbox gear axles 1 are inserted in a plurality of pilot holes 32 simultaneously in quenching process, corrective force between it is mutual is very huge, thereby make its unlikely distortion.
For convenience of middle plate and top board are fixed on support 5, described support 5 is 4, and middle plate and top board are provided with 4 bracket holes 31.
For making automobile gearbox gear axle bear uniformly the corrective force from base plate, middle plate and top board in quenching process, described middle plate is fixed on 1/2nd places that position on support is positioned at automobile gearbox gear shaft length.
For making automobile gearbox gear axle bear uniformly the corrective force from base plate, middle plate and top board in quenching process, for avoiding automobile gearbox gear axle easily to take off after quenching, on described base plate, middle plate and top board, the diameter of pilot hole is than the large 2mm of the diameter of automobile gearbox gear axle simultaneously.
