Description

Technical Field

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] Rotary tools, such as milling cutters, drills, taps, etc., are indispensable tools in mechanical processing. Their cutting performance directly affects processing efficiency, processing quality and processing costs. In order to evaluate the cutting performance of rotary tools, microscopic testing is usually required to observe and analyze the wear morphology, breakage mechanism, coating quality, etc. of the tool. Traditional tool detection methods usually rely on simple fixtures, but these methods have many shortcomings, especially in the microscopic observation of tools.

[0004] Most of the existing rotating tool test fixtures can only perform simple fixing and clamping, which is difficult to meet the requirements of precise positioning, strong versatility and easy operation. When testing rotating tools, the tools need to be accurately positioned and clamped, especially when using high-precision tool testing microscopes. Ensuring that different tools can be observed in the same position is crucial for accurately evaluating and comparing tool wear.

[0005] In terms of microscopic observation, traditional fixtures are usually a set of fixed fixtures, which cannot provide a suitable observation angle and field of view for the tool, which limits the observation results. In addition, some fixed fixtures are not positioned, so after clamping different tools, it is impossible to ensure observation at the same position.

[0006] In addition, after positioning and clamping, the tool still needs to be able to rotate around the tool rotation axis to facilitate the measurement system to observe different positions and angles of the rotating tool without disassembling the tool.

[0007] In addition, the existing tool fixtures are usually designed to only fit specific types of tools and lack versatility. As the types of tools continue to increase, the applicability of fixtures has become increasingly prominent. Many laboratories and factories need to equip different types of tools with different fixtures, which not only increases costs but also reduces testing efficiency. Summary of the invention

After the observation is completed, the first support seat can be removed, and the second matching surface of the first support seat can be replaced to match with the fixed base;

[0063] When it is necessary to observe different positions and angles of the rotating tool to be measured without disassembling it, it is necessary to ensure that the rotating tool to be measured can still rotate around the tool rotation axis after positioning and clamping. In this case, the first fixture needs to be removed and the second fixture needs to be installed:

[0064] The first mating surface of the second support seat is mated with the fixed base, and the rotating support frame is rotated relative to the second support seat so that the end of the connecting rod away from the second support seat makes room for the rotating tool to be measured, so that the rotating tool to be measured passes through the second support seat and the rotating support frame. The reverse movement of the rotating support frame can clamp the rotating tool to be measured, thereby realizing the positioning and clamping of the rotating tool to be measured. The rotating tool to be measured is rotated under the action of external force to realize the observation of the rotating tool to be measured at different positions. After the observation is completed, the first support seat can be removed, and the second mating surface of the first support seat can be replaced to cooperate with the fixed base.

6. A microscopic test fixture for a rotating tool according to claim 4, characterized in that: The first support seat is provided with an inverted T-shaped groove below the support groove, the positioning slide is inserted into the inverted T-shaped groove, a scale is marked on the positioning slide, and the inverted T-shaped groove is connected with the support groove; The support groove is a V-shaped support groove.

7. The microscopic testing fixture for a rotating tool according to claim 1, characterized in that: The second support seat includes an annular disk, the rotating support frame is located on one side of the annular disk, one end of the connecting rod is installed on the annular disk, the outer diameter of the annular disk is larger than the outer diameter of the rotating support frame, a hollow slider is arranged in the middle section of the connecting rod, the hollow slider is hingedly connected to the rotating support frame, a roller is arranged at one end of the connecting rod located inside the rotating support frame, the roller is rotatable relative to the connecting rod, and the roller can contact with the rotating tool to be measured so that the rotating tool to be measured can rotate around the rotating support frame.

8. The microscopic testing fixture for a rotating tool according to claim 7, characterized in that: The annular disk is provided with a support member, and the second nut is installed at the flange of the rotating support frame. The second bolt passes through the support member and the second nut is provided. The second bolt is rotatable relative to the support member. The second bolt and the second nut cooperate through a threaded structure. The second bolt is located in the tangential direction of the rotating support frame. During the rotation of the second bolt, the second nut moves relative to the second bolt, thereby driving the rotation of the rotating support frame.

9. The microscopic testing fixture for a rotating tool according to claim 1, characterized in that: The first supporting seat and the second supporting seat both include a first mating surface and a second mating surface. The first mating surface and the second mating surface can both be engaged with the fixed base. The first supporting seat and the second supporting seat can both be detachably connected to the fixed base.

10. A method for operating a microscopic testing fixture for a rotating tool according to any one of claims 1 to 9, characterized in that: It includes the following: The first support seat is fixed to the microscope base platform, the rotating tool to be tested is placed in the supporting groove, the blade of the rotating tool to be tested is positioned by the positioning component, the distance between the positioning component and the first support seat is adjusted so that the positioning component and the side wall of the supporting groove clamp the rotating tool to be tested, the rotating tool to be tested is observed through the microscope, and different rotating tools to be tested are replaced, because the setting of the positioning component enables different tools to be observed at the same position; The second support seat is fixed to the microscope base platform, and the rotating support frame is rotated relative to the second support seat so that the end of the connecting rod away from the second support seat makes room for the rotating tool to be measured, so that the rotating tool to be measured passes through the second support seat and the rotating support frame. The rotating support frame can clamp the rotating tool to be measured by reverse movement, thereby realizing the positioning and clamping of the rotating tool to be measured, and the rotating tool to be measured is rotated under the action of external force to realize the observation of the rotating tool to be measured at different positions.
