[0023] SeeFigure 1 and Figure 2 The flange workpiece 6 with circular bosses on both ends is widely used in the connection of pipelines, valves and equipment in various fields.

[0024] In order to improve the processing efficiency of a flange workpiece 6 having circular bosses at both ends, the utility model discloses an I-shaped grinding head for a lathe grinder. Figure 1 and Figure 2 The I-shaped grinding head comprises a shank 1, a first grinding wheel 2, a replaceable washer 3, a second grinding wheel 4 and a coupling element 5. One end of the shank 1 passes through the first grinding wheel 2, the replaceable washer 3 and the second grinding wheel 4 in sequence and is detachably connected to the coupling element 5. The distance between the first grinding wheel 2 and the second grinding wheel 4 is adjusted by replacing different thicknesses of the replaceable washer 3.

[0025] See also Figure 2 The tool bar 1 includes a coupling portion 14 for directly or indirectly connecting to the main shaft of the lathe grinder, and the coupling portion 14 is connected to the end of the shaft shoulder 12 away from the sleeve shaft 11. Specifically, the coupling portion 14 is a columnar structure. When in use, the coupling portion 14 of the columnar structure can be clamped on the grinding frame mechanism of the lathe grinder to achieve the installation of the I-shaped grinding head on the grinding frame mechanism.

[0026] See also Figure 2 The joint 14, the shaft shoulder 12 and the sleeve shaft 11 are coaxial.

[0027] The following is a detailed description of the processing process of the I-shaped grinding head for a lathe grinder disclosed in the utility model in processing the above-mentioned flange workpiece.

[0028] Before processing, a replaceable gasket 3 having a thickness consistent with that of the disk body in the target flange workpiece is selected, and one end of the tool rod 1 is detachably connected to the coupling element 5 after passing through the first grinding wheel 2, the replaceable gasket 3 and the second grinding wheel 4 in sequence, so that the tool rod 1, the first grinding wheel 2, the replaceable gasket 3, the second grinding wheel 4 and the coupling element 5 are fixed together to obtain the I-shaped grinding head of the utility model.

[0029] Then, the obtained I-shaped grinding head is clamped on the grinding frame mechanism of the lathe through the joint 14, and the annular cylindrical component to be processed is installed on the clamping jaws of the lathe, and the axis of the annular cylindrical component to be processed is arranged parallel to the axis of the I-shaped grinding head, for example, both are arranged horizontally. The clamping jaw drives the annular cylindrical component to be processed to rotate around its axis, and the grinding frame mechanism drives the I-shaped grinding head to rotate and feed from the outside of the annular cylindrical component to be processed toward the direction close to the axis of the annular cylindrical component to be processed, gradually grinding, and finally obtaining the circular bosses on both sides at the same time in one processing, see Figure 1 .

[0030] See also Figure 2, the tool shank 1 includes a socket shaft 11 and a shoulder 12 connected to the socket shaft 11. The first grinding wheel 2, the replaceable washer 3 and the second grinding wheel 4 are sleeved on the outer side wall of the socket shaft 11 and are all in clearance fit with the socket shaft 11.

[0031] Preferably, the assembly clearances between the first grinding wheel 2 and the socket shaft 11, between the replaceable washer 3 and the socket shaft 11, and between the second grinding wheel 4 and the socket shaft 11 are respectively less than or equal to 0.05 mm.

[0032] In some embodiments, the outer contour of the socket shaft 11 has a non-circular cross-section, such as a D-shaped contour, which is not shown in the figure. By setting the outer contour of the socket shaft 11 to have a non-circular cross-section, relative rotation between the first grinding wheel 2, the second grinding wheel 4 and the socket shaft 11 can be further avoided when the socket shaft 11 rotates, thereby ensuring a stable machining process.

[0033] In some embodiments, the coupling element 5 is a threaded coupling element, and an external thread 13 adapted to the coupling element 5 is provided on the outer side wall of one end of the socket shaft 11 away from the shoulder 12. The coupling element 5 screwed onto the external thread 13 and the shoulder 12 cooperate together to tightly squeeze the first grinding wheel 2, the replaceable washer 3 and the second grinding wheel 4 in the axial direction of the socket shaft 11.

[0034] The threaded coupling element can be an ordinary nut, preferably a locknut structure, to ensure that when the tool shank 1 rotates, the first grinding wheel 2, the replaceable washer 3, the second grinding wheel 4 and the tool shank 1 are stably fixed together and rotate synchronously. The locknut structure can adopt the locknut structures disclosed in the prior art. Since its own structure is not the main improvement point of this application, it will not be elaborated in this application.

[0035] The present utility model also discloses a turning and grinding machine, which includes the above-mentioned I-shaped grinding head for a turning and grinding machine. For the specific structure of the turning and grinding machine, reference can be made to the Chinese patent application with the publication number CN103447818A, a numerical control grinding machine and its working principle, or other turning and grinding machine structures can also be adopted as long as the above-mentioned machining process can be realized.

[0036] The present utility model provides an idea and method for an I-shaped grinding head for a turning and grinding machine and a turning and grinding machine. There are many methods and ways to specifically implement this technical solution. The above-mentioned are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. Each component not clearly defined in this embodiment can be realized by the prior art.
