Problems solved by technology

[0005] However, in the processing method of this configuration, manual work is required in the processing operation, including the handling of the workpiece W, and it is difficult to automate the process, and manual labor increases the manufacturing cost and product cost, and limits the cycle time in the manufacturing process. decrease
[0006] Moreover, since the grinding wheel a is machined into a profile corresponding to the shape of the outer peripheral curved surface of the workpiece W, it is difficult to maintain the grinding accuracy of the workpiece W
In other words, in the shaping and dressing of the grinding wheel surface of the grinding wheel a, when a rotary dresser having an arc-shaped section is used, equipment and facility costs increase, and the shape of the grinding wheel surface of the grinding wheel a Accuracy and grinding accuracy of the outer peripheral curved surface of the workpiece W may vary depending on the shape accuracy of the dresser surface of the rotary dresser, and it is difficult to maintain stable grinding accuracy

Embodiment 1

[0049] The peripheral curved surface grinding equipment of the present invention is Figure 1 to Figure 8A , 8B is shown, and in particular, this kind of grinding equipment is designed to realize the infeed grinding of the outer peripheral curved surface of the workpiece W, which has a curved surface in its outer peripheral portion, such as Figure 10A , 10B And shown in 10C.

[0050] In this preferred embodiment, the workpiece W to be ground is a so-called dome-shaped part, such as a swing bushing for a compressor, and its upper side Wa is a curved surface with an arc-shaped section profile, and the bottom side Wb is a flat surface, and the right side Wc and the left side Wd are flat surfaces almost perpendicular to the bottom side Wb, thus forming a notch. The other surfaces Wb, Wc, Wd except for the outer peripheral curved surface of the upper side Wa have been final processed to the finished surface in the previous process, or are unfinished surfaces that have not been final p...

Embodiment 2

[0117] This preferred embodiment is Figure 9A , 9B Is shown in and is slightly modified in the mounting structure of the outer peripheral curved surface grinding jig 6 on the spindle spindle 10.

[0118] More specifically, in this outer peripheral curved surface grinding jig 6 of the preferred embodiment, the centering mechanism (centering tool) 80 of the outer peripheral curved surface grinding jig 6 is provided at the front end portion of the spindle spindle 10 Installation location.

[0119] The centering mechanism 80 includes an oval groove 80a arranged along a diameter line of the adapter plate 16 on the mounting end surface 16a of the adapter plate 16, and an end surface installed and fixed on the front end mounting portion 10a of the spindle spindle 10 81 on the centering key 80b, and the oval groove 80a and the centering key 80b are assembled in a state of relatively sliding along the longitudinal direction of the oval groove 80a.

[0120] In connection with this, in the il...

Abstract

An outer peripheral curved surface grinding jig of a workpiece capable of efficiently grinding the outer peripheral curved surface with high precision in a workpiece having a curved surface in a portion of its outer periphery. The apparatus includes a fixture body coaxially mounted and fixed on a spindle arbor for supporting and rotating the workpiece and having clamps for detachably clamping and securing the workpiece and the clamping portion has a pair of clamping claws that elastically opens and closes and fixes and supports the workpiece by being held from both sides in a state where the outer peripheral curved surface is exposed. With the workpiece secured and supported by the pair of clamping jaws, the final radial center of the outer peripheral curved surface is located on the axis of rotation of the spindle arbor.

Description

Technical field [0001] The present invention relates to an outer peripheral curved surface grinding jig and an outer peripheral curved surface grinding apparatus of a workpiece, and more particularly to grinding of an outer peripheral curved surface of a workpiece having a curved surface in its outer peripheral portion technology. Background technique [0002] As a swing bushing used in a compressor, a workpiece having a curved surface in a portion of its outer periphery is ground by using a grinding wheel whose contour corresponds to the curved surface of the outer periphery of the object, for example, as in Japanese Patent Application Publication No. Disclosed in 2002-178246. [0003] This grinding is a method of grinding the outer peripheral curved surface of the workpiece W while conveying a plurality of workpieces W along a pair of guides b, b on the conveying route c by using a grinding wheel, which has a grinding wheel corresponding to Such as Picture 11 The grinding wheel...
