Description

Technical Field

[0001] This utility model belongs to the field of circular saw blade hardness testing technology, specifically relating to a metal circular saw blade hardness testing device. Background Technology

[0002] Metal circular saw blades are widely used in the metal processing industry, and their hardness directly affects sawing efficiency and blade life. Currently, some existing metal circular saw blade hardness testing devices on the market usually use traditional hardness testers (such as Rockwell hardness testers), which require cutting samples for destructive testing, resulting in low efficiency and affecting the integrity of the saw blade. In addition, the hardness of the base material and the carbide or high-speed steel material of the saw teeth need to be tested separately, relying on manual positioning, but manual methods lead to low efficiency and poor consistency. Therefore, it is necessary to design a metal circular saw blade hardness testing device. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a device for testing the hardness of metal circular saw blades.

[0004] The objective of this utility model can be achieved through the following technical solution: A metal circular saw blade hardness testing device, comprising a base, characterized in that a rotating worktable is provided on the base, a rotating motor for driving the rotating worktable is provided below the rotating worktable, a positioning shaft is provided at the center of the rotating worktable, a vertical plate is provided on the side of the base, and a fixing mechanism for fixing the metal circular saw blade and a hardness testing mechanism for testing the hardness of the metal circular saw blade are sequentially provided on the vertical plate. The hardness testing mechanism includes a mounting base, a drive motor, an electric push rod, and an ultrasonic hardness probe. The mounting base rests against the vertical plate, the drive motor is horizontally provided on the side of the mounting base, a sliding groove is provided on the upper part of the mounting base, a moving block is slidably connected to the sliding groove, a mounting plate is connected to the moving block, the electric push rod is vertically provided on the mounting plate, the ultrasonic hardness probe is connected to the push rod end of the electric push rod, and a control console is also provided on the base.

[0005] The working principle of this utility model is as follows: The operator places the metal circular saw blade on the rotary worktable, with the center hole passing through the positioning shaft. The operator inputs the detection parameters on the control panel, and the metal circular saw blade is fixed by the fixing mechanism. Then, the drive motor is started, causing the moving block to slide on the slide groove, which moves the mounting plate until the ultrasonic hardness probe moves to the required position according to its stroke. The electric push rod drives the ultrasonic hardness probe to press down to detect the hardness of the base part or the saw teeth part. At the same time, the data is displayed and stored in real time. If multiple tests are required on different parts of the same saw blade, the rotary motor can be driven to rotate the rotary worktable and the metal circular saw blade to be rotated, and the above steps can be repeated for testing. This device does not require manual positioning, which enhances the detection efficiency and data consistency. It is also suitable for metal circular saw blades of different thicknesses and does not damage the metal circular saw blade, which facilitates the detection work.

[0006] The fixing mechanism is located above the rotary table and includes a second mounting plate, a push rod motor, and a fixing component. The second mounting plate is connected to the vertical plate, the push rod motor is vertically mounted on the vertical plate, the push rod end of the push rod motor is connected to a connecting plate, and the fixing component is connected below the connecting plate.

[0007] With the above structure, after the metal circular saw blade is placed, the push rod motor is started, which drives the connecting plate downward, thereby moving the fixing component downward until it touches the metal circular saw blade and is fixed.

[0008] The fastener has a hollowed-out cylindrical shape in the middle and four rectangular fixing plates around it.

[0009] The above structure is used to adapt to the position of the positioning shaft, and at the same time, the base of the metal circular saw blade and the saw teeth are fixed.

[0010] The control console has a display screen and control buttons, and is electrically connected to each mechanism.

[0011] With the above structure, each mechanism can be automatically controlled through the console, and the detection data can be displayed and stored in real time.

[0012] The bottom of the fastener is connected to a rubber pad layer.

[0013] By adopting the above structure and through the design of the rubber pad layer, damage to the surface of the metal circular saw blade is avoided during fixing.

[0014] A displacement sensor is connected to the ultrasonic hardness probe.

[0015] Using the above structure, the displacement sensor detects the moving distance, and the movement stops when the ultrasonic hardness probe is moved to the set position.

[0016] Compared with existing technologies, this metal circular saw blade hardness testing device has the following advantages: by setting up a rotating worktable, a fixing mechanism and a hardness testing mechanism, different parts of the metal circular saw blade can be tested. It is also suitable for metal circular saw blades of different thicknesses and does not require damage to the metal circular saw blade. Compared with manual positioning by operators, it greatly improves the testing efficiency and facilitates the testing work. Attached Figure Description

[0021] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0022] like Figures 1-3As shown, this metal circular saw blade hardness testing device includes a base 1, a rotating worktable 2 mounted on the base 1, a rotary motor 3 driving the rotating worktable 2 below the rotating worktable 2, a positioning shaft 4 at the center of the rotating worktable 2, a vertical plate 5 on the side of the base 1, and a fixing mechanism 7 for fixing the metal circular saw blade 6 and a hardness testing mechanism 8 for testing the hardness of the metal circular saw blade 6 sequentially mounted on the vertical plate 5. The hardness testing mechanism 8 includes a mounting base 81, a drive motor 82, an electric push rod 83, and an ultrasonic sensor. The hardness probe 84 and the mounting base 81 are attached to the upright plate 5. The drive motor 82 is horizontally set on the side of the mounting base 81. The upper part of the mounting base 81 is provided with a sliding groove 85. In this embodiment, the travel distance of the sliding groove 85 is greater than the radius of the circular saw blade. A moving block 86 is slidably connected to the sliding groove 85. A mounting plate 87 is connected to the moving block 86. An electric push rod 83 is vertically set on the mounting plate 87. The ultrasonic hardness probe 84 is connected to the push rod end of the electric push rod 83. A control console 9 is also provided on the base 1.

[0023] The fixing mechanism 7 is located above the rotary table 2 and includes a second mounting plate 71, a push rod motor 72 and a fixing component 73. The second mounting plate 71 is connected to the vertical plate 5. The push rod motor 72 is vertically mounted on the vertical plate 5. The push rod end of the push rod motor 72 is connected to a connecting plate 74. The fixing component 73 is connected below the connecting plate 74.

[0024] With the above structure, after the metal circular saw blade 6 is placed, the push rod motor 72 is started, which drives the connecting plate 74 downward, thereby causing the fixing member 73 to move downward until it touches the metal circular saw blade 6 and is fixed.

[0025] The fixing part 73 has a hollow cylindrical shape in the middle and four rectangular fixing plates around it. The shape of the fixing part 73 is adapted to the position of the positioning shaft 4 and fixes the base and the saw teeth of the metal circular saw blade 6.

[0026] The control console 9 has a display screen 91 and control buttons 92. The control console 9 is electrically connected to each mechanism. In this embodiment, the operator inputs parameters on the control console 9 according to the radius and other dimensions of the metal circular saw blade 6. The control console 9 can automatically control each mechanism, and the detected data can be displayed and stored on the display screen 91 in real time.

[0027] The bottom of the fastener 73 is connected to a rubber pad layer 731; by adopting the above structure, the design of the rubber pad layer 731 avoids damage to the surface of the metal circular saw blade 6 during fixing.

[0028] A displacement sensor 10 is connected to the ultrasonic hardness probe 84. With the above structure, after the operator inputs the parameters, the ultrasonic hardness probe 84 will stop moving when it reaches the set position according to the set displacement distance, which is convenient for detecting the hardness of different parts.

[0029] The working principle of this utility model is as follows: The operator places the metal circular saw blade 6 on the rotary worktable 2, with the center hole passing through the positioning shaft 4. The operator inputs the detection parameters on the control console 9, and the metal circular saw blade 6 is fixed by the fixing mechanism 7. Then, the drive motor 82 is started, causing the moving block 86 to slide on the slide groove 85, driving the mounting plate 87 to move until the ultrasonic hardness probe 84 moves to the required position according to its stroke. The electric push rod 83 drives the ultrasonic hardness probe 84 to press down to perform hardness detection. In this embodiment, ultrasonic hardness technology is used for detection. The ultrasonic hardness probe 84 only needs to lightly touch the surface of the metal circular saw blade 6 without causing damage. At the same time, the data is displayed and stored in real time. In this embodiment, if the hardness of the base part and the saw teeth part of the saw blade are different, or if multiple tests are required on different parts of the same saw blade, the rotary motor 3 can be driven to make the rotary worktable 2 rotate the metal circular saw blade 6, and the above steps can be repeated for detection. This device does not require manual positioning, which enhances the detection efficiency and data consistency. It is also suitable for metal circular saw blades 6 of different thicknesses and does not damage the metal circular saw blade 6, which facilitates the detection work.
