Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bearing processing, and specifically refers to a grinding wheel thinning mechanism for a bearing grinding machine. Background Art
[0002] In order to meet the accuracy requirements of the raceway of a bearing, generally, the raceway needs to be ground by a grinding wheel. To meet the requirements, the grinding wheel needs to be thinned so that its thickness can meet the requirements for bearing raceway grinding. Conventional bearing grinding machines do not have a grinding wheel thinning device, and a diamond pen is used to thin the grinding wheel by hand. Since the force is not easy to control during manual dressing, especially when the grinding wheel is thinned to a certain extent, there is a phenomenon that the grinding wheel is prone to explosion, which poses a hidden danger to personal safety. Moreover, manual thinning will also cause uneven thickness at the same contour of the grinding wheel, resulting in the phenomenon that the workpiece is not ground in place.

[0014] The technical solutions in the embodiments of the present utility model will be clearly and completely described below.
[0015] Such as Figure 1 and Figure 2As shown in the figure, a grinding wheel thinning mechanism for a bearing grinder includes a main body 1 for installing the dressing mechanism. A cylinder 2 is arranged on the main body 1 for installing the dressing mechanism. The tail of the cylinder block of the cylinder 2 is connected to the main body 1 for installing the dressing mechanism through a pin shaft 3. A bearing seat 4 is connected to the main body 1 for installing the dressing mechanism. A bearing is arranged in the bearing seat 4. A connecting shaft 5 is inserted through the bearing. The upper end of the connecting shaft 5 is connected with a swing arm 6. The swing arm 6 is clamped and fixed on the connecting shaft. A nut 7 is arranged at the upper end of the swing arm 6. The nut 7 is connected with the connecting shaft 5 to limit the upper end of the swing arm 6. A connecting column 8 is arranged on the swing arm 6. The piston end of the cylinder 2 is connected with the connecting column 8. The piston end of the cylinder is locked with the connecting column 8 through a nut. The lower end of the connecting shaft 5 is connected with a diamond pen mounting seat 9. An installation hole is machined in the diamond pen mounting seat 9. A diamond pen 10 is arranged at the front end of the installation hole. The diamond pen 10 faces the outer circumferential surface of the grinding wheel 11 to thin the surface of the grinding wheel. The tail of the installation hole is connected with an adjusting screw 12. The adjusting screw 12 adjusts the front and back positions of the diamond pen 10. Among them, the front end of the diamond pen 10 mounting seat is connected with a pen sleeve 13. The diamond pen 10 is connected to the pen sleeve 13. A set screw 14 is arranged at the front end of the pen sleeve 13 to lock the diamond pen 10. An avoidance waist-shaped groove 15 for the set screw 14 is arranged on the diamond pen mounting seat 9. The adjusting screw 12 is screwed on the diamond pen mounting seat 9. The adjusting screw 12 is connected with the tail of the pen sleeve 13 to adjust the front and back positions of the diamond pen 10.
[0016] In this embodiment, the adjusting screw 12 adopts a double-headed thread. A first thread section 16 and a second thread section 17 are machined on the adjusting screw 12. The first thread section 16 is in threaded connection with the tail of the installation hole. The second thread section 17 is in threaded connection with the tail of the pen sleeve 13.
[0017] The pitch of the first thread section 16 is greater than the pitch of the second thread section 17. For example, the pitch of the first thread section 16 is 1.25 mm, and the pitch of the second thread section 17 is 1 mm. During the screwing and adjusting process of the adjusting screw 12, when the first thread section 16 is screwed one turn, the pen sleeve with the diamond pen is pushed forward by 1.25 mm, and when the second thread section 17 is screwed one turn, the pen sleeve is retracted backward by 1 mm. When the adjusting screw 12 is screwed 360°, the adjustment amount of the diamond pen is 0.25 mm. Therefore, when the adjusting screw 12 rotates 1°, the adjustment amount is 0.7 microns. Subsequently, by controlling the screwing angle of the adjusting screw 12, the grinding amount of the diamond pen 10 can be finely adjusted.
[0018] The front end of the cylinder block of the cylinder 2 is connected with a sensor support 18. A waist-shaped groove is machined on the sensor support 18. A position sensor one 19 and a position sensor two 20 are respectively connected to the front and rear ends of the waist-shaped groove. The piston end of the cylinder 2 moves between the position sensor one 19 and the position sensor two 20. The position sensor one 19 and the position sensor two 20 sense the position of the piston end.
