[0001] The utility model relates to the technical field of circular saw blade stress detection, in particular to a circular saw blade stress detection device. Background Art

[0002] When an object is deformed due to external factors, internal forces that interact with each other are generated between the various parts of the object to resist the action of this external factor and try to restore the object from its position after deformation to its position before deformation. The internal force per unit area at a certain point on the cross section under investigation is called stress. When testing the stress of the saw blade, it needs to be installed on the stress testing equipment and then tested by the stress detector.

[0003] For example, a large-diameter circular saw blade stress detector with publication number CN217304229U, in which the through hole at the center of the circular saw blade is mounted on the outer wall of the support column, and the support table supports the bottom of the circular saw blade, and then the turntable is driven upward by the support device, so that the turntable drives the support column and the support table to move upward. After the support column moves upward, the bottom end of the square column extends into the square hole, and the bottom end of the cylinder contacts the top end of the circular saw blade, and the support column continues to move upward driven by the turntable, and at the same time, the top end of the support table is limited by the cylinder, so that multiple groups of top rods support the bottom end of the support table, and then the support table and the cylinder clamp and fix the circular saw blade, thereby improving the convenience of fixing the circular saw blade, and then the square column is driven to rotate by turning on the first motor, so that the square column drives the circular saw blade to rotate through the support column, thereby improving the convenience of the detector for detecting the circular saw blade, and the support table is supported by a spring, so as to improve the buffering effect of the support table during the placement of the circular saw blade, thereby improving the convenience of protecting the circular saw blade.

[0004] When the circular saw blade is fixed to the stress detection device for detection in the above patent, the positions of the stress detector and the detection rod are relatively fixed and can only be moved up and down but not horizontally. The detection range of the saw blade is relatively limited and the saw blade cannot be fully detected. Utility Model Content

[0012] Preferably, a connecting shaft is provided on one side of the round rod, and the bottom of the connecting shaft is movably connected to the base via a rotating shaft.

[0013] Preferably, a spiral groove is provided on the outer side of the connecting shaft, and the spiral groove is slidably connected to the round rod, and a cleaning brush is fixedly connected to the top of the connecting shaft.

[0014] Compared with the prior art, the circular saw blade stress detection device has the following beneficial effects: by installing a gear on the top of the dual-axis motor, the tooth surface of the gear can drive the rack frame to move back and forth by alternately meshing with the racks on both sides inside the rack frame, and the rack frame can drive the stress detector and the scale rod to move back and forth, so as to perform a more comprehensive detection of the saw blade; by arranging a cross bar on one side of the bracket, the round bar on one side of the cross bar will move together when the bracket moves up, and the connecting shaft will be rotated by toggling the spiral groove in the connecting shaft, at which time the connecting shaft can drive the cleaning brush to the top of the saw blade, and when the saw blade rotates, the cleaning brush can clean the upper surface of the saw blade to prevent debris from affecting the detection effect of the scale rod and the stress detector.

[0015] 1. When performing stress detection on a circular saw blade, it is necessary to install it on the detection device and then perform detection through the stress detector. The scale rod contacts the saw blade through the ball at the bottom. When the saw blade becomes uneven, the scale rod will move up and down. The deformation size of the saw blade can be measured through the scale on its surface. In order to expand the detection range of the stress detector and the scale rod, a gear is installed on the top of the dual-axis motor, with one side of the gear being a smooth surface and the other side being a tooth surface. The tooth surface of the gear can drive the rack frame to reciprocate by alternately meshing with the racks on both sides of the rack frame. The rack frame can drive the stress detector and the scale rod to reciprocate, so as to perform a more comprehensive detection of the saw blade. The above operations can increase the detection range of the circular saw blade stress detection equipment.

[0016] 2. When performing stress testing on a circular saw blade, in order to prevent debris on the saw blade from affecting the detection of the scale rod and the stress detector, a cross bar is set on one side of the bracket. The round bar on one side of the cross bar will move together when the bracket moves up, and the connecting shaft will be rotated by the spiral groove in the connecting shaft. Since the spiral range of the spiral groove is one-quarter of a circle, that is, 90°, the connecting shaft can be driven to rotate 90°. At this time, the connecting shaft can drive the cleaning brush to the top of the saw blade. When the saw blade rotates, the cleaning brush can clean the upper surface of the saw blade to prevent debris from affecting the detection effect of the scale rod and the stress detector. The above operation can facilitate the cleaning of the saw blade detected on the circular saw blade stress detection equipment to ensure the detection effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In specific implementation, when stress detection is performed on a circular saw blade, it is necessary to install it on a detection device, and then detect it through the stress detector 4. The scale rod 14 contacts the saw blade through the ball at the bottom. When the saw blade is uneven, the scale rod 14 will move up and down, and the deformation size of the saw blade can be measured through the scale on its surface. In order to expand the detection range of the stress detector 4 and the scale rod 14, a gear 8 is installed on the top of the dual-axis motor 6, one side of the gear 8 is a smooth surface and the other side is a tooth surface. The tooth surface of the gear 8 is meshed with the racks on both sides of the rack frame 9, which can drive the rack frame 9 to reciprocate. When the rack frame 9 moves, it can directly pull the connecting rod 11 to drive the electric push rod 12 and the stress detector 4 to move, so as to perform multi-directional detection on the rotating saw blade at the bottom;

[0026] The other side of the rack frame 9 can drive the scale rod 14 to move through the slider 13. When the scale rod 14 is affected by the uneven surface of the saw blade and moves up and down, it can slide on the outside of the slider 13 through the slide groove. When the scale rod 14 moves back and forth, the contact range with the saw blade can be increased, and the saw blade can be more comprehensively detected. The slide rod 15 can limit the scale rod 14 and the connecting rod 11 when they move. In this way, the detection range of the circular saw blade stress detection equipment can be increased through the above operation.

[0027] See also Figure 2 and Figure 4 A cross bar 16 is fixedly connected to one side of the bracket 3, and a round rod 17 is fixedly connected to one side of the cross bar 16; a connecting shaft 18 is provided on one side of the round rod 17, and the bottom of the connecting shaft 18 is movably connected to the base 1 through a rotating shaft; a spiral groove 19 is provided on the outer side of the connecting shaft 18, and the spiral groove 19 is slidably connected to the round rod 17, and a cleaning brush 20 is fixedly connected to the top of the connecting shaft 18, and the connecting shaft 18 forms a rotating structure with the base 1 through the rotating shaft, and the connecting shaft 18, the spiral groove 19 and the round rod 17 form a sliding structure.

[0028] In a specific implementation, when stress detection is performed on a circular saw blade, in order to prevent debris on the saw blade from affecting the detection of the scale rod 14 and the stress detector 4, a cross bar 16 is arranged on one side of the bracket 3. The round rod 17 on one side of the cross bar 16 moves together when the bracket 3 moves upward, and the connecting shaft 18 is driven to rotate by the spiral groove 19 in the connecting shaft 18. Since the number of spiral turns of the spiral groove 19 is 0.25, the connecting shaft 18 can be driven to rotate 90°. At this time, the connecting shaft 18 can drive the cleaning brush 20 to The cleaning brush 20 is above the saw blade and in contact with the saw blade. When the saw blade rotates, the cleaning brush 20 can clean the upper surface of the saw blade to prevent debris from affecting the detection effect of the scale rod 14 and the stress detector 4. When the detection is completed, the hydraulic rod 2 can drive the bracket 3 to move downward. At this time, the round rod 17 can move the connecting shaft 18 to reset it, so that the cleaning brush 20 is separated from the top of the saw blade, which can facilitate the loading and unloading of the saw blade. In this way, the above operation can facilitate the cleaning of the saw blade detected on the circular saw blade stress detection equipment to ensure the detection effect.

[0029] To sum up: when using the circular saw blade stress detection equipment, first place the saw blade on the top of the bracket 3, then start the hydraulic rod 2 to push the bracket 3 to drive the saw blade to move upward, when the square groove on the top of the bracket 3 is connected to the square rod 7 at the bottom of the dual-axis motor 6, the dual-axis motor 6 can be started to drive the square rod 7 and the bracket 3 to rotate, at this time, the stress detector 4 and the scale rod 14 can detect the stress and deformation of the saw blade, which is the characteristic of the circular saw blade stress detection equipment, and the content not described in detail in this description belongs to the existing technology known to professional and technical personnel in this field.
