<Industrial Application Field> The present invention relates to a correction roller position adjustment mechanism for a workpiece (object to be hardened) to be induction hardened. <Conventional Technology> Hereinafter, the conventional technology will be explained with reference to FIG. 4. Conventionally, when hardening the surface of a cylindrical or multiaxial workpiece 10, the workpiece 10 is arranged horizontally, and the centers 11, 11 of both end surfaces of the workpiece 10 are set at a pair (not shown) in the figure. Support with center pin. At this time, the workpiece 10 is bent, so in order to correct the bending, the workpiece 10 is placed on a pair of correction rollers 20, 20 provided on the shaft 22 and a correction roller 30 provided on the shaft 32. From, work 1
While rotating the workpiece 10, a high-frequency heating coil (not shown) is placed close to the workpiece 10 to heat the surface of the workpiece 10, and then a quenching cooling liquid is injected onto the workpiece 10.
The diameters of the correction rollers 20 and 30 are the same, and the center distance between the correction rollers 20 and 30 is shorter than the diameter of the correction roller 20. Further, the shafts 22 and 32 are supported by bearings 23 and 33 fixed to a base plate 40, respectively. The height of the center pin mentioned above is fixed,
After supporting the workpiece 10 between the center pins, the correction rollers 20 and 30, which had been lowered in advance, are raised to a predetermined position according to the diameter of the workpiece 10, and the correction rollers 20 and 30 correct the bending of the workpiece 10. Support it in a state where it is not in use. For this purpose, there is usually a scale plate 45 indicating the vertical distance h between the centers 11, 11 of both end faces of the workpiece 10 and, for example, the centers 21, 31 of the straightening rollers 20, 30, and a scale plate 45 for this scale plate 45. Guideline 46

That is, the vertical distance h corresponding to the diameter of the workpiece 10 must be calculated, which is time-consuming. In particular, when the diameter of the workpiece 10 changes frequently, it is troublesome to have to calculate the vertical distance h each time. The present invention was devised in view of the above circumstances, and if the diameter of the workpiece is known, the above vertical distance h
To provide a correction roller position adjustment mechanism capable of moving the correction roller to a predetermined position where the workpiece supported between center pins can be supported without bending the workpiece without having to calculate each time. <Means for Solving the Problem> The present invention is a correction roller position adjustment mechanism for correcting the bending of a workpiece formed in a cylindrical shape or a multistage shaft shape and subjected to induction hardening. A straightening device having two or more straightening rollers on which a workpiece is placed, both ends of which are supported by center pins, a rotating handle having a pointer, and converting the rotational movement of the rotating handle into linear movement in the vertical direction of the straightening device. and a scale plate provided around the rotary handle, and the scale plate has a mechanism for raising and lowering the straightening device to a position corresponding to the diameter of the workpiece or in response to changes in the size. The present invention is characterized in that a scale is provided at the position at which the rotary handle is to be rotated to indicate the dimensions or changes in the dimensions. <Operation> When the rotary handle is rotated to the position of the scale corresponding to the diameter of the workpiece placed on the straightening device, the straightening device is in a position where it can support the workpiece without bending the workpiece supported between the center pins. come. <Example> An example of the present invention will be described below with reference to the drawings. 1 and 2 are drawings for explaining the first embodiment of the present invention, in which FIG. 1e is a front explanatory view and FIG. 1b is a plan explanatory view. Figure 2a,
b is a diagram illustrating the principle of the present invention, and shows cases where the diameters of the workpieces are a and a+Δa, respectively. FIG. 3 is an explanatory front view of the second embodiment of the present invention. Note that the same reference numerals are given to the same parts as those described in the related art section. In the first embodiment, the correction device 100 includes:
A pair of correction rollers 20, 20 attached to a shaft 22 supported by a bearing 23, a correction roller 30 attached to a shaft 32 supported by a bearing 33, and these bearings 23, 33 are fixed. A base plate 40 is provided. The correction roller position adjustment mechanism includes a correction device 100, a rack 41 provided on a base plate 40, and a pinion 4 meshed with the rack 41.
2, a knob 44 that rotates the pinion 42 via the shaft 43, and a pointer 47 attached to the knob 44.
and a scale plate 48 having a scale corresponding to the diameter of the workpiece 10 or changes in the diameter. The centers 11, 11 of both end faces of the workpiece 10 are
As shown in Figure 1b, a pair of center pins 1
2 and 12, and the workpiece 10 is supported by correction rollers 20 and 30 so as not to bend. Next, the principle of this embodiment will be explained. In FIG. 2a, a, d, and l are the diameter dimensions of the workpiece 10, and the straightening rollers 20, 30, respectively.
and the distance between the straightening rollers 20 and 30. However, the correction rollers 20 and 30 are arranged so that l<d. The vertical distance h between the centers 11, 11 of both end faces of the workpiece 10 and the centers 21, 31 of the straightening rollers 20, 30 is h=[(a+d) 2 /2 2 (l/2) 2 ] 1/2 Now, if d=30mm, a=30mm, and l=26mm, then h=27.04mm. Next, the diameter dimension a of workpiece 10 is 20 mm and 40 mm.
Table 1 below shows the results of calculating h when the value is changed by 1 mm between mm. However, Δa is the increase/decrease value (mm) of a from 30 mm, and Δh is the increase/decrease value (mm) from h (27.04 mm) when a is 30 mm.

It is assumed that the scale at the position of the pointer 47 on the scale plate 48 is 20. From now on, repeat the above and guideline 47.
As shown in FIG. 1, a scale corresponding to the diameter dimension a of the workpiece 10 may be written in the rotation range of the workpiece 10. Further, the scale for the pointer 47 can be written in increments or decreases from 30 mm of the diameter of the workpiece 10. In this case, the value of Δa corresponding to the diameter dimension a may be written in Table 1 instead of the scale of a. Next, using the correction roller position adjustment mechanism of this embodiment, for example, a cylindrical workpiece 10 with a diameter of 38 mm is
Consider the case of hardening. First, the centers 11, 11 of both end surfaces of the workpiece 10 are supported between the center pins 12, 12. Next, in order to raise the orthodontic device 100 that had been lowered in advance, the knob 44 is turned to move the pointer 47 to the scale plate 48.
Place it at the 38th scale position. Then, the rotation of the knob 44 is caused by the rotation of the rack 41 via the shaft 43 and pinion 42.
As a result, the base plate 40 is vertically moved to a position where the vertical distance h between the center pins 12, 12 and the centers 21, 31 of the correction rollers 20, 30 is 31.42 mm. And the correction rollers 20, 30
The upper part supports the workpiece 10 so that it does not bend. Next, while the work 10 is rotated by a rotating device (not shown), the surface of the work 10 is heated by a high frequency heating coil (not shown), and then the work 10 is heated.
The hardening of the workpiece 10 is completed by injecting the hardening cooling liquid. The second embodiment differs from the first embodiment in the following points, so only the different points will be explained. The base plate 40 to which the bearings 23 and 33 are fixed is raised and lowered by rotating a bolt 51 rotatably attached to the induction hardening device main body 53 and a knob 52 provided on the top of the bolt 51. . knob 52
A pointer 54 is provided on the knob 52, and a scale plate 55 with graduations in the same manner as in the first embodiment is provided on the knob 52.
It is located around the. In this embodiment as well, the straightening device 100 can be raised and lowered in accordance with the diameter of the workpiece 10, as in the first embodiment. <Effects of the invention> As explained above, the present invention supports a cylindrical workpiece with both ends supported by center pins, and is equipped with two or more straightening rollers that are rotatably attached or forcibly driven. It has a device, a rotating handle that operates the lifting and lowering of the straightening device, and a device that converts the rotational movement of the rotating handle into a linear movement in the lifting and lowering direction of the straightening device. A scale is provided at a position where the rotary handle should be turned in order to raise and lower the orthodontic device in accordance with the dimension or in response to a change in the dimension. Therefore, according to the correction roller position adjustment mechanism of the present invention, if the diameter of a cylindrical workpiece or a change in diameter is known, the position of the scale corresponding to the diameter or change in diameter can be adjusted. By turning the rotary handle, the straightening device can be moved to a position where the centers of both end faces can support the workpiece supported between the center pins without causing any bending. That is, it is possible to save the effort of calculating the lifting distance of the correction apparatus, which was conventionally required when moving the correction apparatus up and down. The scale of the scale plate is still indicated by the diameter of the workpiece, but since the diameter of the workpiece is generally an integer, it is sufficient to set the pointer to an integer value, making the scale adjustment process quick and easy. Furthermore, by indicating with the above-mentioned scale, the change range of the scale is expanded than before, and by providing the scale over the entire rotation range of the pointer, the distance interval between each scale is increased compared to the conventional linear scale. This makes the scale easier to read. Furthermore, since the rotating handle and the pointer are in the same body, there are advantages such as less movement of the line of sight.
