Description

Technical Field

[0001] This utility model belongs to the field of circular saw blade production technology, and specifically relates to a thickness detection device for circular saw blade production. Background Technology

[0002] Thickness testing of circular saw blades involves measuring the actual thickness of the saw blade substrate (usually avoiding the saw teeth) at multiple locations to assess the uniformity of the produced circular saw blade thickness and whether it meets specified tolerances. The purpose is to ensure that the saw blade operates smoothly at high speeds, with high cutting accuracy and low vibration, and to prevent uneven stress, deformation, or breakage caused by excessive thickness deviation, which directly affects cutting quality and efficiency. Testing is usually performed using high-precision thickness gauges (such as calipers, micrometers, etc.), with a focus on monitoring the substrate thickness and its parallelism (parallelism of both sides).

[0003] According to Chinese Patent Publication No. CN212133519U, a circular saw blade substrate thickness measuring instrument is disclosed. The instrument includes a base, a driving device, and a testing device. The testing device includes a positioning rod and two sliding plates. The positioning rod is fixed to a fixing block. The two sliding plates are provided with through holes and sleeved on the positioning rod, which can movably clamp the two sides of the circular saw blade. Magnetic blocks are provided at the ends of the sliding plates. The distance between the two sliding plates can be adjusted according to the different thicknesses of the circular saw blade.

[0004] However, the aforementioned devices all have problems in combining with existing technologies for circular saw blade thickness detection. Since the thickness detection of cutting circular saw blades generally adopts a sampling method and uses calipers to measure multiple positions on the saw blade surface, the caliper measuring surface is relatively long. When there are local depressions on the saw blade surface, the measurement result reflects the "span" value of the protruding parts at both ends of the depression area, which cannot accurately capture the actual minimum thickness at the depression. This detection blind spot means that unqualified saw blades with surface depressions may not be effectively identified and may enter the market. Utility Model Content

[0005] In response to the problem that related technologies cannot accurately capture the actual minimum thickness of the recess, and that this blind spot may cause substandard saw blades with surface recesses to be undetected and enter the market, this utility model proposes a thickness detection device for the production of circular saw blades to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a thickness detection device for the production of circular saw blades, including a base, a transmission mechanism is provided on the surface of the base, a single-point measuring mechanism is also provided on the surface of the base, a reciprocating transverse movement mechanism is provided at the measuring end of the single-point measuring mechanism, the reciprocating end of the reciprocating transverse movement mechanism is connected to the transmission end of the transmission mechanism, and a data amplification mechanism is provided inside the single-point measuring mechanism. The transmission mechanism is used to drive the reciprocating end of the circular saw blade and the reciprocating lateral movement mechanism to rotate synchronously, so that the reciprocating end drives the lateral movement end of the reciprocating lateral movement mechanism to move, so that the lateral movement end drives the measuring end of the single-point measuring mechanism to reciprocate on the surface of the circular saw blade.

[0007] Furthermore, the transmission mechanism includes a support frame, which is fixedly connected to the base surface. A motor is fixedly installed inside the support frame, and a placement disk is fixedly connected to the output shaft of the motor. A fixing nut is threaded onto the surface of the placement disk.

[0008] Furthermore, the single-point measuring mechanism includes a fixed frame, which is fixedly connected to the surface of the base. A limiting rod is fixedly connected inside the fixed frame. A measuring frame is slidably connected to the surface of the limiting rod, and the measuring frame is slidably connected inside the fixed frame. A spring is sleeved on the surface of the limiting rod, with one end of the spring fixedly connected to the surface of the measuring frame and the other end of the spring fixedly connected inside the fixed frame.

[0009] Furthermore, a fixed rod is fixedly connected inside the measuring frame, a detection block is slidably connected to the surface of the fixed rod, the detection block is slidably connected inside the measuring frame, a ball bearing is rotatably connected to one end of the detection block, and a scale is fixedly connected to the surface of the fixed frame.

[0010] Furthermore, the reciprocating lateral movement mechanism includes a connecting rod, which is fixedly connected to one side of the detection block and slidably connected inside the measuring frame. A sliding plate is fixedly connected to one end of the connecting rod, and a positioning plate is slidably connected to the surface of the sliding plate.

[0011] Furthermore, a turntable is fixedly connected to the outer wall of the placement tray, and a reciprocating groove is formed on the surface of the turntable. A transverse rod is slidably connected in the reciprocating groove, and the transverse rod is slidably connected inside the fixed frame. One end of the transverse rod is fixedly connected to a positioning plate.

[0012] Furthermore, the data amplification mechanism includes a rack, which is fixedly connected to one side of the measuring frame. A pinion meshes with one side of the rack, and a large gear meshes with the surface of the pinion. The pinion is rotatably connected inside the fixed frame. A display panel is fixedly connected to one side of the fixed frame, and the large gear is rotatably connected inside the display panel. A pointer is fixedly connected to one end of the large gear, and the pointer is slidably connected to the surface of the display panel.

[0013] This utility model has the following beneficial effects: 1. This utility model drives the cutting circular saw blade and the reciprocating end of the reciprocating lateral movement mechanism to rotate synchronously through a transmission mechanism. The reciprocating end drives the lateral movement end of the reciprocating lateral movement mechanism to move, so that the lateral movement end drives the measuring end of the single-point measuring mechanism to reciprocate on the surface of the cutting circular saw blade. Combined with the continuous rotation of the saw blade, the measuring end forms a spiral scanning trajectory, realizing continuous single-point contact measurement of the entire surface of the saw blade. This solution overcomes the "span effect" caused by the long measuring surface of traditional calipers, and the single-point probe can accurately locate and feedback the true thickness value of the depression, eliminate the detection blind zone, and ensure the accurate identification of surface depression defects.

[0014] 2. This utility model utilizes the principle that when the surface flatness of a circular saw blade needs to be displayed, the ball bearings in contact with the saw blade surface are squeezed and moved, causing the detection block and measuring frame linked to it to slide axially within the fixed frame along the guide rod. The displacement of the measuring frame synchronously drives the rack fixed to it to move, and the rack then meshes with and drives the pinion to rotate. The pinion drives the large gear, and finally drives the pointer coaxial with the large gear to rotate on the display panel, thereby displaying and quantifying the data changes of the saw blade surface flatness in real time, so that the flatness of the circular saw blade can be seen intuitively.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0019] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0020] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0021] Please see Figures 1-6 As shown, this utility model is a thickness detection device for the production of circular saw blades, including a base 1, a transmission mechanism 2 is provided on the surface of the base 1, a single-point measuring mechanism 3 is also provided on the surface of the base 1, a reciprocating transverse movement mechanism 4 is provided at the measuring end of the single-point measuring mechanism 3, the reciprocating end of the reciprocating transverse movement mechanism 4 is connected to the transmission end of the transmission mechanism 2, and a data amplification mechanism 5 is provided inside the single-point measuring mechanism 3. The transmission mechanism 2 is used to drive the cutting circular saw blade and the reciprocating end of the reciprocating transverse mechanism 4 to rotate synchronously, so that the reciprocating end drives the transverse end of the reciprocating transverse mechanism 4 to move, so that the transverse end drives the measuring end of the single-point measuring mechanism 3 to reciprocate on the surface of the cutting circular saw blade.

[0022] By fixing the circular saw blade to the transmission end of the transmission mechanism 2, the circular saw blade is positioned at the measuring end inside the single-point measuring mechanism 3. The single-point measuring mechanism 3 drives the measuring end to contact the circular saw blade through elastic force, thereby detecting the thickness of the circular saw blade. During multi-point measurement, the transmission end of the transmission mechanism 2 drives the circular saw blade and the reciprocating end of the reciprocating lateral movement mechanism 4 to rotate synchronously. This causes the reciprocating end to drive the lateral movement end of the reciprocating lateral movement mechanism 4 to move, so that the lateral movement end drives the measuring end of the single-point measuring mechanism 3 to reciprocate on the surface of the circular saw blade. This allows for multi-point detection of the surface of the circular saw blade, and the flatness of the surface can also be detected. The detection data is displayed through the data amplification mechanism 5.

[0023] The transmission mechanism 2 drives the cutting circular saw blade and the reciprocating end of the reciprocating lateral movement mechanism 4 to rotate synchronously. The reciprocating end drives the lateral movement end of the reciprocating lateral movement mechanism 4 to move, so that the lateral movement end drives the measuring end of the single-point measuring mechanism 3 to reciprocate on the surface of the cutting circular saw blade. Combined with the continuous rotation of the saw blade, the measuring end forms a spiral scanning trajectory, realizing continuous single-point contact measurement of the entire surface of the saw blade. This solution overcomes the "span effect" caused by the long measuring surface of traditional calipers, and the single-point probe can accurately locate and feedback the true thickness value of the depression, eliminate the detection blind zone, and ensure the accurate identification of surface depression defects.

[0024] In one embodiment, the transmission mechanism 2 includes a support frame 201, which is fixedly connected to the surface of the base 1. A motor 202 is fixedly installed inside the support frame 201. The output shaft of the motor 202 is fixedly connected to a placement disk 203, and a fixing nut 204 is threadedly connected to the surface of the placement disk 203.

[0025] By placing the circular saw blade on one end of the placement plate 203, and then threading the fixing nut 204 onto the surface of the placement plate 203 to fix the circular saw blade, the motor 202 is started, causing the placement plate 203 to rotate slowly, so that the placement plate 203 drives the circular saw blade to rotate slowly and synchronously.

[0026] In one embodiment, the single-point measuring mechanism 3 includes a fixed frame 301, which is fixedly connected to the surface of the base 1. A limiting rod 302 is fixedly connected inside the fixed frame 301. A measuring frame 303 is slidably connected to the surface of the limiting rod 302 and is slidably connected inside the fixed frame 301. A spring 304 is sleeved on the surface of the limiting rod 302. One end of the spring 304 is fixedly connected to the surface of the measuring frame 303, and the other end of the spring 304 is fixedly connected inside the fixed frame 301. A fixed rod 305 is fixedly connected inside the measuring frame 303. A detection block 306 is slidably connected to the surface of the fixed rod 305 and is slidably connected inside the measuring frame 303. A ball bearing 307 is rotatably connected to one end of the detection block 306. A scale 308 is fixedly connected to the surface of the fixed frame 301.

[0027] By placing the circular saw blade between the measuring frames 303, the spring 304 drives the measuring frame 303 to slide on the surface of the limit rod 302 and inside the fixing frame 301, causing the measuring frame 303 to move the detection block 306, and causing the detection block 306 to drive the ball bearing 307 to contact both sides of the circular saw blade to detect the thickness of the circular saw blade. The specific data is displayed by observing the scale 308.

[0028] In addition, the thickness of the circular saw blade is calculated by recording the position data of the outer edges of the two measuring frames 303 at the scale 308, and then subtracting the height of the two detection blocks 306 and the ball bearing 307. The height of the two detection blocks 306 and the ball bearing 307 is the overall height after the detection blocks 306 and the ball bearing 307 are connected and installed, multiplied by two. This is a fixed height that only needs to be measured once and then marked. No further measurement is required.

[0029] In one embodiment, the reciprocating transverse mechanism 4 includes a connecting rod 401, which is fixedly connected to one side of the detection block 306 and slidably connected inside the measuring frame 303. One end of the connecting rod 401 is fixedly connected to a sliding plate 402, and a positioning plate 403 is slidably connected to the surface of the sliding plate 402. A turntable 404 is fixedly connected to the outer wall of the placement plate 203. A reciprocating groove 405 is provided on the surface of the turntable 404, and a transverse rod 406 is slidably connected inside the reciprocating groove 405. The transverse rod 406 is slidably connected inside the fixed frame 301, and one end of the transverse rod 406 is fixedly connected to the positioning plate 403.

[0030] When the placement plate 203 rotates, it drives the turntable 404 to rotate synchronously. The turntable 404 drives the transverse rod 406 to reciprocate transversely within the fixed frame 301 through the reciprocating groove 405. This causes the other end of the transverse rod 406 to drive the positioning plate 403 to move transversely. The positioning plate 403 then drives the sliding plate 402 and the connecting rod 401 to move transversely within the measuring frame 303. This causes the detection block 306 to reciprocate transversely within the measuring frame 303 and on the surface of the fixed rod 305. The detection block 306 drives the ball bearing 307 to reciprocate and roll on the surface of the circular saw blade to detect the surface of the circular saw blade. When a depression appears on the surface of the circular saw blade, the ball bearing 307 drives the detection block 306 and the measuring frame 303 to slide on the surface of the limiting rod 302 and inside the fixed frame 301, thereby compressing the spring 304. At the same time, the sliding plate 402 slides inside the positioning plate 403.

[0031] In one embodiment, the data amplification mechanism 5 includes a rack 501, which is fixedly connected to one side of the measuring frame 303. A pinion 502 meshes with one side of the rack 501, and a large gear 503 meshes with the surface of the pinion 502. The pinion 502 is rotatably connected inside the fixed frame 301. A display disk 504 is fixedly connected to one side of the fixed frame 301, and the large gear 503 is rotatably connected inside the display disk 504. A pointer 505 is fixedly connected to one end of the large gear 503, and the pointer 505 is slidably connected to the surface of the display disk 504.

[0032] When the measuring frame 303 moves, it drives the rack 501 to move synchronously, causing the rack 501 to drive the pinion 502 to rotate, which in turn drives the gear 503 to rotate. The gear 503 then drives the pointer 505 to rotate on the display panel 504, thus displaying the dimensions of any indentations on the surface of the circular saw blade in real time. First, observe the initial value of the pointer 505 on the display panel 504 when the circular saw blade is positioned on the measuring frame 303. During movement detection, subtract or add to the overall thickness of the circular saw blade, and observe the real-time change in the pointer 505 on the display panel 504 based on the initial value to determine the thickness of a single point on the circular saw blade. When observing flatness, simply remember the initial value of the pointer 505 on the display panel 504, and then observe the changes in the pointer 505's value on the display panel 504 to visually assess the flatness difference of the circular saw blade.

[0033] Among them, since the flatness requirement of the circular saw blade is usually higher than the thickness requirement, the flatness directly affects the cutting accuracy, material loss and cut quality. For example, in wood processing, an uneven saw blade may cause rough cuts, increased board waste, and even affect subsequent processing. Therefore, it is necessary to magnify the flatness data for easy viewing. The principle of the pinion 502 driving the large gear 503 to amplify the displacement of the pointer 505 is that the small angular displacement of the pinion 502 is converted into a larger angular displacement of the large gear 503 through the gear transmission ratio. Then, through the leverage effect of the pointer 505, the angular displacement is further amplified into a significant linear displacement of the tip of the pointer 505.

[0034] Through the above technical solution, 1. By placing the circular saw blade between one end of the placement plate 203 and the measuring frame 303, and then threading the fixing nut 204 onto the surface of the placement plate 203 to fix the circular saw blade, the spring 304 drives the measuring frame 303 to slide on the surface of the limit rod 302 and inside the fixing frame 301, causing the measuring frame 303 to drive the detection block 306 to move, causing the detection block 306 to drive the ball bearing 307 to contact both sides of the circular saw blade to detect the thickness of the circular saw blade. The specific data is displayed by observing the scale 308. The motor 202 is started, causing the motor 202 to drive the placement plate 203 to rotate slowly, so that the placement plate... 203 drives the cutting circular saw blade to rotate synchronously and slowly. When the placement plate 203 rotates, it drives the turntable 404 to rotate synchronously. The turntable 404 drives the transverse rod 406 to reciprocate transversely inside the fixed frame 301 through the reciprocating groove 405. This causes the other end of the transverse rod 406 to drive the positioning plate 403 to move transversely. The positioning plate 403 drives the sliding plate 402 and the connecting rod 401 to move transversely inside the measuring frame 303. This causes the detection block 306 to reciprocate transversely inside the measuring frame 303 and on the surface of the fixed rod 305. The detection block 306 drives the ball bearing 307 to roll reciprocally on the surface of the cutting circular saw blade, thus performing real-time detection on the surface of the cutting circular saw blade.

[0035] 2. When a depression appears on the surface of the circular saw blade, the ball bearing 307 drives the detection block 306 and the measuring frame 303 to slide on the surface of the limit rod 302 and inside the fixed frame 301. When the measuring frame 303 moves, it drives the rack 501 to move synchronously, causing the rack 501 to drive the pinion 502 to rotate, which in turn drives the gear 503 to rotate. The gear 503 then drives the pointer 505 to rotate on the surface of the display disk 504, thereby displaying the size of the depression on the surface of the circular saw blade in real time.
