Description

Technical Field

[0001] The utility model relates to the technical field of roller core polishing, in particular to roller core surface polishing equipment. Background Art

[0002] Existing roller core polishing equipment is generally a grinding wheel machine or a sanding belt machine. The polishing equipment is installed on a small slide of a lathe. During polishing, the roller core is clamped in a three-jaw chuck of the lathe. By controlling the position of the small slide, the grinding wheel or sanding belt generates friction with the roller core to achieve a polishing effect.

[0003] Whether it is a grinding wheel or a grinding belt, the area of ​​contact with the circumference of the roller core in an instant is very small. If you want to speed up the polishing speed, you usually increase the speed of the lathe spindle. This method consumes more power and needs to be improved. Utility Model Content

[0007] The beneficial effects of the utility model are as follows: when in use, the roller core is coaxially fixed on the three-jaw chuck of the lathe, and the small slide plate of the lathe is operated to make the sanding belt contact the surface of the roller core. Due to the flexible characteristics of the sanding belt, the deeper the roller core enters the notch, the larger the contact area between the sanding belt and the circumference of the roller core, and under the action of the spring, the sanding belt is always kept in a tensioned state. Therefore, the device can effectively increase the contact area between the sanding belt and the circumference of the roller core, and can improve the polishing efficiency and reduce power consumption without increasing the spindle speed of the lathe; and when the shape of the sanding belt is determined, the electromagnet can be turned on to fix the position of the slider, thereby keeping the sanding belt stable and having high stability.

DETAILED DESCRIPTION

[0011] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the protection scope of the utility model.

[0012] Example

[0013] like Figure 1-Figure 2 As shown, the roller core surface polishing device includes a base 1, which is fixed to a small slide 120 of a lathe by bolts, a column 11 is fixedly connected to the base 1, and a longitudinal plate 12 perpendicular to the ground is fixedly connected to the side of the column 11 facing the imaginary line of the main axis of the lathe, and the upper end and the lower end of the longitudinal plate 12 on the side away from the column 11 are respectively horizontally fixedly connected to a motor 2 and a mounting shaft 121, a driving wheel 3 is fixedly connected to the main axis of the motor 2, and a driven wheel 4 is rotatably mounted on the mounting shaft 121, a notch 122 is provided on the longitudinal plate 12 between the driving wheel 3 and the driven wheel 4, and a middle part of the longitudinal plate 12 is spaced along the direction of the column 11 pointing to the notch 122. There are two mounting blocks 5, and two guide rods 6 are fixedly connected horizontally between the two mounting blocks 5. A slider 7 is commonly sleeved on the two guide rods 6. An electromagnet 8 is connected to the side of the slider 7 facing the longitudinal plate 12. The electromagnet 8 fits the longitudinal plate 12. A mounting shaft 2 71 is horizontally fixedly connected to the side of the slider 7 away from the longitudinal plate 12. A tensioning wheel 9 is rotatably installed on the mounting shaft 2 71. Two springs 10 are abutted between the mounting block 5 and the slider 7 near the notch 122. The spring 10 is a compression spring, and the two springs 10 are respectively sleeved on the two guide rods 6. A sanding belt 110 is commonly sleeved on the driving wheel 3, the driven wheel 4 and the tensioning wheel 9.

[0014] In actual use, the roller core 130 is coaxially fixed on the three-jaw chuck of the lathe, and the small slide plate 120 of the lathe is manipulated to make the sanding belt 110 contact the surface of the roller core 130. Due to the flexibility of the sanding belt 110, the deeper the roller core 130 enters the notch 122, the larger the contact area between the sanding belt 110 and the peripheral surface of the roller core 130. Under the action of the spring 10, the sanding belt 110 always remains in a tensioned state. Therefore, the device can effectively increase the contact area between the sanding belt 110 and the peripheral surface of the roller core 130, and can improve the polishing efficiency and reduce power consumption without increasing the spindle speed of the lathe. After determining the shape of the sanding belt 110, the electromagnet 8 can be turned on to fix the position of the slider 7, thereby keeping the sanding belt 110 stable and having high stability.
