Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of saw blades, and in particular relates to a saw blade flatness detection device. Background Art
[0002] A saw blade is a tool used to cut materials, usually wood, metal and other materials. Saw blades can have different shapes and sizes to suit different cutting needs. Depending on the use requirements, saw blades have different specifications for the pitch, tooth shape, tooth thickness / number of teeth, etc.
[0003] Of course, there are certain requirements for the quality of saw blades. The quality of saw blades includes whether all indicators of the saw blades are qualified, including the surface flatness of the saw blades. The surface flatness of the saw blades has a great influence on the cutting effect during the saw blade cutting process. If the surface of the saw blade is not flat enough, the cutting gap will be large and easy to crack. Therefore, when inspecting the saw blades, the flatness of the saw blades also needs to be inspected. However, due to the inconsistency between the tooth thickness of the saw blades and the thickness of the base after brazing, as well as the influence of burrs on the edge of the saw blades, there will be gaps when the saw blades are placed directly on the plane, which affects the measurement results. Therefore, how to simply, conveniently and accurately detect the flatness of the saw blade base is a problem that needs to be solved at present. Utility Model Content
[0004] The main purpose of the utility model is to provide a saw blade flatness detection device, through which the flatness of the saw blade base body can be tested simply, conveniently and accurately.
[0005] In order to achieve the above purpose, the utility model provides a saw blade flatness detection device, which includes a detection platform and a test tool. A vertical fixed rod is arranged on the detection platform, a horizontal fixed rod is arranged on the vertical fixed rod, a flatness meter is fixedly installed on the horizontal fixed rod, and the test tool is used to place the saw blade to be measured.
[0006] The saw blade flatness detection device provided by the utility model has the advantages that after the flatness meter is fixed by a resin fixing rod and a transverse fixing rod, the saw blade to be measured is placed on a test fixture. After the surface of the saw blade to be measured contacts with the flatness meter, whether the flatness of the saw blade is qualified is determined by moving the test fixture and observing the flatness meter. This scheme is simple and convenient for detecting the flatness of the saw blade.
[0007] In a possible implementation, the test fixture includes a test board, and a plurality of magnets are arranged on the test board, and the top surfaces of the plurality of magnets are flush with each other and parallel to the bottom surface of the test fixture. The saw blade is placed on the magnets on the test board, and the position of the magnets can avoid the teeth and burrs of most saw blades and can absorb the saw blade, so that the saw blade is not easy to move during the test, there is no gap between the contact surfaces, the stability is good, and the test result is more accurate.
[0008] In a possible implementation, two limit stops are provided at one end of the test plate, and the height of the limit stops is greater than the height of the magnet. The limit stops are provided to further limit the position of the saw blade, making it more stable during the detection process.
[0009] In a possible implementation, the flatness meter is a dial gauge or a micrometer, which can be used to accurately measure the flatness of the saw blade surface.
[0010] In a possible implementation, the number of the magnets is set to three, wherein two magnets are symmetrically arranged on the test board, and the third magnet is arranged on a perpendicular bisector of a connecting line of the two symmetrically arranged magnets.
