The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1 and fig. 2, an embodiment of the invention provides a method for detecting a period of a tool machining apparatus, which is applied to the tool machining apparatus 100. The tool machining apparatus 100 machines a tool according to a tool machining program. The tool machining apparatus 100 includes a holder 10, a grinding wheel 20, a transfer mechanism 30, and a detection device 40. The fixed base 10 and the transfer mechanism 30 are disposed at an interval. The transfer mechanism 30 is used for positioning and driving the tool. The grinding wheel 20 is installed at one end of the fixing base 10 and is used for grinding the cutter. The detection device 40 is fixed at one end of the fixed seat 10 far away from the grinding wheel 20 and is used for detecting the tool online. It should be understood by those skilled in the art that the above-mentioned on-line detection of the tool means that the tool does not need to be removed from the transplanting mechanism 30, and the detection device 40 and the transplanting mechanism 30 are directly matched with each other to obtain an image of the tool, so as to analyze the relevant dimension information of the tool according to the obtained image. In the present embodiment, the machining program includes a chip groove machining program, an end tooth machining program, and an end blade machining program. The chip groove machining program comprises parameters required for machining a chip groove, the end tooth machining program comprises parameters for machining an end tooth, and the end blade machining program comprises parameters required for machining an end blade.
The method for periodically detecting the cutter processing equipment comprises the following steps:
s101: and (4) machining a chip groove of the cutter.

S102: and judging whether the machined tool needs to be detected according to the first detection period, if so, executing step S103, and if not, executing step S106.
In the present embodiment, the first detection period may be one detection every five cutters, but is not limited thereto, and in other embodiments, the detection period may be set according to circumstances.
S103: and acquiring the front angle and the large diameter of the cutter on line.
Specifically, the grinding wheel 20 stops rotating and retreats backward to avoid collision with the tool. The moving mechanism 30 drives the tool to the detection range of the detection device 40, and the detection device 40 obtains the first end face image of the tool, and analyzes and processes the front angle and the size information of the major diameter of the tool. In the present embodiment, the position where the detection device 40 acquires the first side image of the tool is determined by the processing result of the first end face image, but is not limited thereto.
S104: and judging whether the front angle and the major diameter of the cutter meet the first preset checking parameter, if so, executing step S106, and if not, executing step S105.

It can be understood that when the sizes of the rake angle and the major diameter of the cutter can be corrected, the corresponding parameters in the chip groove machining program are modified and the chip groove is machined again; when the front angle and the large diameter of the cutter cannot be corrected, the cutter is scrapped, so that the cutter needs to be changed and reworked. Since the rake angle and the major diameter obtained in step S103 do not meet the preset requirements, regardless of whether the rake angle and the major diameter of the tool are correctable, the corresponding parameters in the chip groove machining program must be modified, and the modification of the parameters may be consistent or inconsistent in the case of being correctable and uncorrectable.
S106: and processing the end teeth and the end blades of the cutter.
The transfer mechanism 30 returns the tool to the machining position, i.e., a position where the grinding wheel 20 can grind the tool. The grinding wheel 20 and the transfer mechanism 30 move according to the end tooth machining program, and the end teeth of the tool are ground and machined by the tool.
S107: and judging whether the machined tool needs to be detected according to the second detection period, if so, executing the step S108, and if not, executing the step S111.
In the present embodiment, the second detection period may be one detection every five cutters, but is not limited thereto, and in other embodiments, the detection period may be set according to circumstances. In some embodiments, the first detection period and the second detection period may not be equal.
S108: and acquiring the sizes of the end teeth and the end edges of the cutter on line.
Specifically, the grinding wheel 20 stops rotating and retreats backward to avoid collision with the tool. The moving and carrying mechanism 30 drives the tool to the detection range of the detection device 40, and the detection device 40 obtains the second end face image and the second side face image of the tool, and analyzes and processes the information of the sizes of the end teeth and the end edges of the tool.
