Description

Technical Field

[0001] The utility model relates to the technical field of cylindrical grinders, in particular to a numerically controlled finishing cylindrical grinder for roller making. Background Art

[0002] The cast roll is a cast steel roll with a carbon content of 0.4% to 2.1%. It is not only a deformation tool, but also plays the role of a water-cooled crystallizer in the casting and rolling process. When processing the cast roll, it is necessary to use a cylindrical grinder to grind and polish its surface.

[0003] When using the existing cylindrical grinder for casting roll processing, the operation of limiting and fixing the casting roll is relatively cumbersome. It takes a long time in the early stage to limit and fix the two ends of the casting roll. The operation is not simple enough, which affects the grinding efficiency of the casting roll. Utility Model Content

[0004] The present invention relates to a CNC finishing cylindrical grinder for roller manufacturing, which solves the problem that the conventional cylindrical grinder for casting roller processing is complicated in operation for limiting and fixing the casting roller, and takes a long time in the early stage to limit and fix the two ends of the casting roller, which is not easy to operate and affects the grinding efficiency of the casting roller.

[0005] In a first aspect of the present disclosure, a CNC finishing cylindrical grinder for roller manufacturing is provided, which specifically comprises: a connecting base; the connecting base is fixedly connected to the driving shaft of the grinder, three movable clamps are installed in a circumferential shape inside the connecting base, the end of the casting roller is inserted into the connecting base, and the movable clamps are in contact with the end of the casting roller; a movable ring is connected to the outside of the connecting base, and the movable ring is connected to the three movable clamps; a spiral coil is connected to the outside of the connecting base, and a handle is provided on the outside of the spiral coil in a circumferential shape.

[0006] Furthermore, the connection base is provided with a movable hole in a circumferential shape on the outside, a fixed inclined groove is provided at one end of the movable hole, a movable clamp is located in the movable hole, a T-shaped inclined block A is provided at one end of the movable clamp, and the T-shaped inclined block A is slidably connected in the fixed inclined groove.

[0007] Furthermore, the movable ring is slidably connected to the outside of the connecting base, and a sliding block is provided in a surrounding shape on the inner side of the movable ring, and the sliding block is slidably connected to a movable hole provided in the connecting base.

[0008] Furthermore, a movable bevel groove is provided inside the slider, and a T-shaped bevel block B is provided at the other end of the movable clamping block. The T-shaped bevel block B is slidably connected to the movable bevel groove, the T-shaped bevel block A slides with the fixed bevel groove, and the T-shaped bevel block B slides with the movable bevel groove, which plays a guiding effect on the movement of the movable clamping block.

[0009] Furthermore, an external thread is provided on the outside of the connecting base, and the screw coil is threadedly connected to the external thread provided on the outside of the connecting base. The screw coil is in contact with the movable ring. When the end of the casting roller is inserted into the connecting base, the screw coil is rotated, and the screw coil pushes the movable ring to move outward. The movable ring drives the three movable clamps to move inward synchronously, thereby clamping and limiting the end of the casting roller.

[0010] Furthermore, a spring is mounted on the outside of the connection base, one end of the spring is in contact with the connection base, and the other end of the spring is in contact with the coil. The spring applies thrust to the coil to increase the rotational resistance of the coil, thereby effectively preventing the coil from loosening.

[0011] Furthermore, a magnetic block is installed in a ring shape inside the movable ring, and the magnetic block is connected with the spiral coil by attraction. After the casting roller is polished, the spiral coil is rotated in the reverse direction. The spiral coil is affected by the magnetic attraction force to drive the movable ring to move inward, and the movable ring drives the three movable clamps to move outward synchronously, so that the movable clamp is separated from the end of the casting roller.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] When the utility model is in use, the T-shaped inclined block A slides with the fixed inclined groove, and the T-shaped inclined block B slides with the movable inclined groove, so as to guide the movement of the movable clamping block; when the end of the casting roller is inserted into the connecting base, the spiral ring is rotated, and the spiral ring pushes the movable ring to move outward, and the movable ring drives the three movable clamping blocks to move inward synchronously, thereby reducing the interval between the three movable clamping blocks, so that the movable clamping block contacts the end of the casting roller, and the end of the casting roller is clamped and limited. The grinding machine can drive the casting roller to rotate and perform grinding operations, thereby ensuring the stability of the casting roller grinding process, making the casting roller clamping and limiting more simple and time-saving, and improving the casting roller grinding processing efficiency.

[0014] In addition, a thrust is applied to the spiral coil by the spring to increase the rotational resistance of the spiral coil, and the spiral coil is effectively prevented from loosening during the clamping and limiting process of the end of the casting roller, thereby further ensuring the clamping and limiting effect of the end of the casting roller; after the grinding of the casting roller is completed, the spiral coil is rotated in the opposite direction, and the spring gradually contracts. The spiral coil is affected by the magnetic force and drives the movable ring to move inward, and the movable ring drives the three movable clamping blocks to move outward synchronously, thereby increasing the spacing between the three movable clamping blocks, so that the movable clamping block is separated from the end of the casting roller, and the end of the casting roller can be taken out from the connecting base, and the operation is easier.

[0015] Other advantages, objectives and features of the present invention will be reflected in part through the following description, and in part will be understood by those skilled in the art through research and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
