In the present embodiment, the height direction is perpendicular to both the first direction 112 and the second direction 113. Through the intermeshing of gear, can drive the rotation of fixing base 120, and then drive the rotatory rotation of target work piece 121, wherein, fixing base 120 can be the chuck, can fix the target work piece 121 of different specifications size through the chuck, and fixing base 120 also can be the clamping jaw or other frock clamps that can realize that target work piece 121 clamping is fixed. Of course, in other embodiments, the fixing base 120 may also be connected to the motor 142, and the motor 142 drives the fixing base 120 to rotate, so as to drive the target workpiece 121 to rotate.

In addition, the present invention also provides a chamfering method of the chamfering apparatus 100 as described in any one of the above, and the chamfering method includes the steps of:

step 1: as shown in fig. 1, the target workpiece 121 is fixed to the fixing base 120, and the grinding wheel 144 is fixed to the driving element 141.

The target workpiece 121 is fixed on the fixing seat 120 by using a clamp or other clamping tools, the center of the target workpiece 121 is fixed and adjusted by using the choke plug thimble 114, the axial direction of the target workpiece 121 is parallel to the first direction 112, and the grinding wheel 144 is fixed on the driving element 141 by using the clamp or other clamping tools, so as to prevent the coating end face 123 from being subjected to eccentric force in the chamfering and grinding process, and ensure that the distance between the center of the grinding wheel 144 and the center of the target workpiece 121 to the top surface 111 is consistent.

Step 2: the moving mechanism 130 is driven to operate until the grinding wheel 144 abuts on the target workpiece 121, and the grinding wheel 144 and the target workpiece 121 rotate relatively.

In the present invention, the rotation speed of the target workpiece 121 is 60r/min to 80r/min, and in a specific setting, the rotation speed of the target workpiece 121 is preferably one of 60r/min, 65r/min, 70r/min, 75r/min, and 80r/min, and certainly, the rotation speed of the target workpiece 121 is not limited to the above range, and may be other values in the range of 60r/min to 80r/min, and may be set according to actual requirements. The rotating speed of the grinding wheel 144 is 100r/min-150r/min, and in a specific setting, the rotating speed of the grinding wheel 144 is preferably one of 100r/min, 110r/min, 120r/min, 130r/min, 140r/min and 150r/min, of course, the rotating speed of the grinding wheel 144 is not limited to the above range, and may be other values in the range of 100r/min-150r/min, and may be set according to actual requirements. It should be noted that the rotation speed of the grinding wheel 144 needs to be greater than the rotation speed of the target workpiece 121, and in the grinding process, the coating end face 123 only receives the grinding force with the same rotation direction as the target workpiece 121, and the ground chamfer surface is smooth, so that the yield of the target workpiece 121 is improved.

And step 3: moving the moving mechanism 130 in the first direction 112 until the coated end face 123 has ground a chamfer.

When the moving mechanism 130 is moved along the first direction 112 and further drives the cutting mechanism 140 to move along the first direction 112, the moving speed is not too high, and the cutting mechanism 140 needs to be kept moving at a constant speed, so that the problem that the coating end face 123 is cracked and cracked due to too high moving speed and the yield and the production efficiency of the target workpiece 121 are seriously affected due to the fact that the impact force applied to the coating end face 123 is large is solved.

And 4, step 4: and (5) closing the machine table 110 and the motor 142 to finish grinding the chamfer of the coating end face 123.

The chamfering method is used for chamfering the coating end face 123 of the target workpiece 121, fixing the target workpiece 121 and the grinding wheel 144 by using the tool fixture, driving the moving mechanism 130 to move along the first direction 112 and/or the second direction 113 until the grinding wheel 144 abuts against the target workpiece 121, enabling the grinding wheel 144 and the target workpiece 121 to rotate relatively, continuing to move the moving mechanism 130 along the first direction 112, starting chamfering and grinding the coating end face 123, and realizing chamfering and grinding the coating end face 123. The chamfering method enables the coating end face 123 to only receive grinding force in the same rotating direction as the target workpiece 121 in the grinding process, can effectively reduce the risks of cracking and edge breakage of the coating 122, is simple in chamfering process, and can obviously improve the yield and production efficiency of the target workpiece 121.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
