[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0019] Reference Figure 1-3 A high-precision cone reamer shape detection device includes a cone reamer 1 and a mounting seat 4. A blade 11 is provided on the lower side of the cone reamer 1. The blade 11 is provided in multiple groups and is evenly arranged on the lower side of the cone reamer 1. When the blade 11 is installed on the cone reamer 1, there is an installation or processing error, which needs to be detected;
[0020] A fixed bracket 3 is provided on the inner side of the mounting seat 4, and a detection mold 2 is provided on the fixed bracket 3. The detection mold 2 is provided with multiple groups and arranged in a circular array. The multiple groups of detection molds 2 are arranged corresponding to the blades 11. A card slot adapted to the detection mold 2 is opened on the fixed bracket 3, which is used to install the detection mold 2 adapted to the shape of different conical reamers 1, thereby improving the practicality of the detection equipment. The detection mold 2 and the fixed bracket 3 are detachably connected, and a cavity for accommodating the detection mold 2 and the fixed bracket 3 is provided on the inner side of the mounting seat 4. An adjustment gasket is provided between the mounting seat 4 and the detection mold 2 to ensure that the detection mold 2 is installed reliably and accurately;
[0021] A template groove is provided inside the detection mold 2, and the template groove is adapted to the conical reamer 1. The template groove is the shape of the reaming hole processed by the standard conical reamer 1. The detection mold 2 is embedded with a detection contact at the template groove. The detection contact includes a positive contact 21 and a negative contact 22. The positive contact 21 and the negative contact 22 are both against the blade 11. If the positive contact 21 and the negative contact 22 are both against the blade 11, it means that the blade 11 is reliably installed and has an accurate shape.
[0022] A detection connector 5 is provided on one side of the detection mold 2, and the positive contact 21 and the negative contact 22 are electrically connected to the detection connector 5 respectively. Resistor elements are provided in the positive contact 21 and the negative contact 22. A resistance tester is connected to the detection connector 5. The positive contact 21, the negative contact 22 and the blade 11 form a circuit. The resistance tester detects the resistance in the circuit. If there is a resistance value, it means that the positive contact 21 and the negative contact 22 are in contact with the blade 11. If the resistance value is infinite, it means that the circuit is open and the positive contact 21 or the negative contact 22 has no contact with the blade 11.
[0023] Working principle:
[0024] A template groove for detecting the position of the blade 11 is processed in the detection mold 2. The template groove is consistent with the size of the reaming hole to be processed. The conical reamer 1 is placed in the template groove. The positive contact 21 and the negative contact 22 are in contact with the blade 11. The resistance tester detects the resistance between the positive contact 21 and the negative contact 22 to determine whether the positive contact 21 or the negative contact 22 is in contact with the blade 11. The conical reamer 1 is placed by rotating it for multiple times to determine whether the shape of the conical reamer 1 meets the requirements, thereby realizing rapid detection of the shape and size of the conical reamer 1.
[0025] When the blade 11 is longer, multiple negative contacts 22 can be set. The multiple negative contacts 22 are connected in parallel. The more parallel resistances there are, the smaller the total resistance is. When a parallel negative contact 22 is not in contact with the blade 11, the resistance measured by the resistance tester becomes larger, so it can be determined whether the appearance of the blade 11 is standard.
[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
