For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0029] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0030] Referring to Figure 1 , Figure 1 A structural schematic diagram of a detection device for a saw blade of a power tool provided by an embodiment of the present application; in combination Figures 2 to 6 In particular, a detection device 100 for a saw blade 42 of a power tool 400, comprising: a detection table 10, a detection assembly 20, an adjusting member 30, and the power tool 400; the detection table 10 is provided with a mounting position 11 for mounting the power tool 400; the detection assembly 20 is arranged on the detection table 10, and the detection assembly 20 is provided with a calibration position for the saw blade 42 of the power tool 400 to pass through; the adjusting member 30 is arranged on the detection table 10 and connected with the power tool 400 to drive the power tool 400 to move in a first direction 101; wherein when the adjusting member 30 drives the power tool 400 to move in the first direction 101, a first end surface 421 of the saw blade 42 abuts against an inner wall of the calibration position to calibrate the perpendicularity and parallelism of the saw blade 42 relative to the power tool 400.

[0031] Optionally, the power tool 400 is usually a circular saw or a cutting machine.

[0032] Optionally, the first direction 101 is the width direction of the detection table 10.

[0033] Optionally, the adjusting member 30 is an adjusting nut.

[0034] In particular, the detection table 10 is the base of the entire detection device 100, and the detection table 10 is provided with the mounting position 11 for positioning and carrying the power tool 400 to be calibrated; the detection assembly 20 is fixedly installed on the detection table 10, and the detection assembly 20 is provided with the calibration position; the calibration position can be passed through by the saw blade 42 of the power tool 400, and the inner wall of the calibration position provides a physical reference for subsequent calibration of the perpendicularity and parallelism of the saw blade 42 relative to the power tool 400; the adjusting member 30 is also arranged on the detection table 10 and forms a driving link with the power tool 400 located in the mounting position 11, and by operating the adjusting member 30, the power tool 400 can be driven to move linearly in the first direction 101 in the mounting position 11.

[0035] In combination with the specific work condition, the operator first places the electric tool 400 to be calibrated on the mounting position 11 of the detection table 10 and positions it; then the operator rotates the detection assembly 20 so that the calibration position on the detection assembly 20 is aligned with and sleeved into the saw blade 42 of the electric tool 400, and the saw blade 42 passes through the calibration position, at which time the saw blade 42 is constrained by the inner wall of the calibration position; then the operator operates the adjusting member 30 provided on the detection table 10, i.e., rotates the adjusting nut, which generates a linear driving force to push the entire electric tool 400 to move steadily along the first direction 101, i.e., the width direction of the detection table 10; as the electric tool 400 moves, the saw blade 42 that has broken through the calibration position also moves; since the calibration position is fixed, the saw blade 42 will move relative to the inner wall of the calibration position; by continuously rotating the adjusting member 30 until a significant resistance is felt, which indicates that the first end surface 421 of the saw blade 42 has completely abutted against the corresponding inner wall of the calibration position, achieving abutment; when the first end surface 421 of the saw blade 42 abuts against the inner wall of the calibration position, the spatial orientation of the saw blade 42 is uniquely determined by the reference defined by the inner wall, thereby synchronously achieving the calibration of the perpendicularity and parallelism of the saw blade 42 relative to the electric tool 400 itself.

[0036] Further, please refer to Figures 1 to 3 The detection table 10 is provided with a connecting seat 12; the detection assembly 20 includes a calibration member 21, one end of which is hinged to the connecting seat 12; the calibration position is provided on the calibration member 21; wherein, in the process of rotating the calibration member 21 to the second direction, the saw blade 42 enters the calibration position.

[0037] Specifically, the connecting seat 12 is provided on one side of the detection table 10; the detection assembly 20 specifically includes the calibration member 21, which is in the shape of a long strip or a plate, and the calibration member 21 is provided with the calibration position; one end of the calibration member 21 is hinged to the connecting seat 12 through a rotating shaft, so that the calibration member 21 can rotate in the plane perpendicular to the table top 15 of the detection table 10 about the hinged shaft; the rotating direction of the calibration member 21 includes the second direction and the third direction opposite to the second direction; wherein, the process of rotating the calibration member 21 to the second direction is the process of sleeving the saw blade 42 into the calibration position; similarly, the process of rotating the calibration member 21 to the third direction is the process of separating the saw blade 42 from the calibration position.

[0038] In one example, when the saw blade 42 needs to be calibrated, the operator holds the free end of the calibration member 21, i.e., the end away from the connecting seat 12, and rotates it to the second direction; in this process of rotation, the calibration position opened on the connecting member moves and gradually sleeves towards the saw blade 42, until the saw blade 42 completely enters and passes through the calibration position, completing the preliminary alignment.

[0039] Further, please refer toFigure 1 The detection table 10 is provided with a locking piece 14; the detection assembly 20 further comprises a cooperating piece 22, which is arranged on the calibration piece 21 and is arranged opposite the locking piece 14; when the locking piece 14 and the cooperating piece 22 abut, the calibration piece 21 is locked relative to the connecting seat 12.

[0040] Optionally, the locking piece 14 is a bolt arranged on the detection table 10.

[0041] Optionally, the cooperating piece 22 can be a protrusion, which is fixedly arranged on the calibration piece 21.

[0042] Specifically, the calibration piece 21 is provided with the cooperating piece 22 on the side away from the detection table 10, and the detection table 10 is provided with the locking piece 14 corresponding to the cooperating piece 22 and cooperating with the cooperating piece 22; when the calibration piece 21 is rotated to the saw blade 42 entering the calibration position, the locking piece 14 is tightened, so that the end of the locking piece 14 abuts tightly with the cooperating piece 22 on the calibration piece 21; through the bolt clamping, the calibration piece 21 is firmly locked and cannot be rotated randomly around the hinge shaft, thereby ensuring the stability in the subsequent calibration stage.

[0043] Further, please refer to Figures 1 to 3 The detection table 10 further comprises a fixing seat 13, which is arranged opposite the connecting seat 12 and is provided with a limiting groove 131; the calibration piece 21 is provided with a clamping block 23 away from the connecting seat 12; the clamping block 23 is rotatably arranged on the calibration piece 21; when the saw blade 42 enters the calibration position, the clamping block 23 rotates relative to the calibration piece 21 and enters the limiting groove 131 to limit the calibration piece 21 from rotating in a third direction opposite the second direction.

[0044] Specifically, the detection table 10 is further provided with the fixing seat 13 on the other end away from the connecting seat 12, and the fixing seat 13 is provided with the limiting groove 131; the opening direction of the limiting groove 131 is away from the connecting seat 12; the clamping block 23 is arranged on the free end of the calibration piece 21 away from the hinge seat, and the clamping block 23 is rotatably arranged on the calibration piece 21 through a connecting shaft, so that the clamping block 23 can rotate relative to the calibration piece 21.

[0045] In one example, when the operator rotates the calibration piece 21 in the second direction and makes the saw blade 42 enter the calibration position, the calibration piece 21 reaches the working position, at which time the clamping block 23 can be rotated to align and enter the limiting groove 131 of the fixing seat 13; when the clamping block 23 enters the limiting groove 131, the calibration piece 21 can be limited from rotating in the third direction opposite the second direction, and the calibration piece 21 is further locked.

[0046] It should be noted that the second direction and the third direction are not specifically limited in the present application; the second direction can be clockwise rotation of the calibration piece 21 with the connecting seat 12 as the axis, or counterclockwise rotation of the calibration piece 21 with the connecting seat 12 as the axis; and the third direction is the opposite direction of the second direction.

[0047] Further, referring to Figures 4 to 6 , the electric tool 400 comprises a bottom plate 41, the bottom plate 41 is installed on the installation site 11; and the bottom plate 41 is provided with a slot 411; the saw blade 42 is located in the slot 411; wherein the adjusting piece 30 is connected to the side of the bottom plate 41 away from the slot 411.

[0048] Preferably, the bottom plate 41 is a cuboid.

[0049] Further, referring to Figure 4 , the electric tool 400 further comprises a driving motor 43, the saw blade 42 is arranged on the driving motor 43, and the driving motor 43 is fixed on the bottom plate 41 by bolts.

[0050] Specifically, the electric tool 400 comprises a bottom plate 41, during calibration operation, the bottom plate 41 is installed on the installation site 11 of the detection table 10, at this time the driving motor 43 is located on the side of the bottom plate 41 away from the calibration piece 21; the floor is provided with a slot 411, a part of the saw blade 42 extends out of the slot 411 and enters the calibration site of the calibration piece 21; the adjusting piece 30 is connected to or connected to the side of the bottom plate 41 away from the slot 411; by screwing the adjusting piece 30, the linear motion directly acts on the side wall of the bottom plate 41, thereby pushing the movement of the entire electric tool 400.

[0051] Further, referring to Figure 4 and Figure 5 , the calibration site is provided with an adjusting groove 211; wherein during the movement of the bottom plate 41 driven by the adjusting piece 30 in the first direction 101, the saw blade 42 moves relative to the adjusting groove 211; when the first end surface 421 of the saw blade 42 abuts against the first wall surface 212 of the adjusting groove 211, the perpendicularity of the saw blade 42 relative to the bottom plate 41 is calibrated.

[0052] Specifically, the calibration site is an adjusting groove 211 provided on the calibration piece 21, the adjusting groove 211 has two parallel long side inner walls; wherein the long side inner wall of the adjusting groove 211 away from the adjusting piece 30 is defined as the first inner wall; the first inner wall is the reference surface of calibration.

[0053] In one example, during the movement of the bottom plate 41 driven by the adjusting piece 30 in the first direction 101, the saw blade 42 passing through the adjusting groove 211 moves relatively in the adjusting groove 211; when the first end surface 421 of the saw blade 42 contacts and completely abuts against the first wall surface 212 of the adjusting groove 211, the calibration action is triggered.

[0054] Further, referring to Figures 4 to 6 , the first wall surface 212 is configured to be perpendicular to the table surface 15 of the detection table 10; when the first end surface 421 abuts against the first wall surface 212, the first end surface 421 is perpendicular to the plane of the bottom plate 41 parallel to the table surface 15 of the detection table 10.

[0055] Specifically, since the bottom plate 41 of the power tool 400 is placed on the detection table 10, the bottom plate 41 is parallel to the table surface 15 of the detection table 10; when the first end surface 421 of the saw blade 42 abuts against the first wall surface 212, the first end surface 421 of the saw blade 42 is forced to be perpendicular to the table surface 15 of the detection table 10; since the bottom plate 41 is parallel to the table surface 15 of the detection table 10, the perpendicular relationship between the first end surface 421 of the saw blade 42 and the horizontal plane 413 of the bottom plate 41 is forced to be guaranteed.

[0056] Further, referring to Figures 4 to 6 , the first wall surface 212 is further configured to be parallel to the vertical reference plane 412 of the bottom plate 41; when the first end surface 421 abuts against the first wall surface 212, the first end surface 421 is parallel to the vertical reference plane 412 to calibrate the parallelism of the saw blade 42 relative to the power tool 400.

[0057] Optionally, the vertical reference plane 412 is a plane perpendicular to the table surface 15 of the detection table 10 along the length direction of the bottom plate 41.

[0058] While the first end surface 421 of the saw blade 42 maintains the perpendicular relationship with the horizontal plane 413 of the bottom plate 41, the first wall surface 212 is also parallel to an inherent vertical reference plane 412 on the bottom plate 41; the numerical reference plane can be the side vertical surface of the bottom plate 41; therefore, when the first end surface 421 of the saw blade 42 abuts against the first side wall, the parallel relationship between the first end surface 421 of the saw blade 42 and the vertical reference plane 412 of the bottom plate 41 is also guaranteed; as can be seen, by ensuring the abutting relationship of the first wall surface 212, a single abutting action can simultaneously convey the two constraints of perpendicularity and parallelism; the compliance calibration of the saw blade 42 and the bottom plate 41 of the power tool 400 is achieved.

[0059] Further, referring to Figure 5 , the detection table 10 is provided with a plurality of limiting blocks 16, and the plurality of limiting blocks 16 are arranged around the detection table 10; the plurality of limiting blocks 16 jointly surround to form a mounting position 11.

[0060] Specifically, on the table surface 15 of the detection table 10, a plurality of limiting blocks 16 are arranged, which are arranged around the detection table 10 and jointly surround to form a positioning area matching the shape of the bottom plate 41 of the power tool 400, i.e. to form the mounting position 11, so as to facilitate the power tool 400 to be quickly placed and accurately positioned.

[0061] Further, refer to Figure 7 , Figure 7 A flow chart of a detection method of a saw blade of a power tool is provided for the embodiments of the present application. The present application also provides a detection method of a saw blade of a power tool, which can be applied to the detection device in any of the above examples. The detection method comprises: S1: mounting the power tool to the mounting position and adjusting the power tool so that the relative position between the bottom plate of the power tool and the driving motor of the saw blade is adjustable; S2: rotating the detection assembly so that the saw blade enters the calibration position of the detection assembly; S3: controlling the adjusting member to drive the power tool to move along the first direction relative to the detection table until the first end surface of the saw blade abuts against the inner wall of the calibration position; S4: when the first end surface of the saw blade abuts against the inner wall of the calibration position, the saw blade is vertically arranged relative to the bottom plate, and the saw blade is arranged in parallel with the vertical reference plane of the bottom plate, so as to complete the calibration of parallelism and perpendicularity synchronously.

[0062] Specifically, the power tool 400 is mounted to the mounting position 11 of the detection table 10, so that the bottom plate 41 of the power tool 400 is positioned correctly by the limiting block 16; then, the fastening bolts connecting the bottom plate 41 and the driving motor 43 of the power tool 400 are loosened; so that the relative position between the driving motor 43 and the bottom plate 41 becomes adjustable, which provides adjustment space for the subsequent driving motor 43 and the saw blade 42 relative to the calibration position.

[0063] Further, the calibration member 21 is rotated to the second direction to ensure that the adjusting groove 211 of the calibration member 21 gradually fits into the saw blade 42 during the rotation, and finally the saw blade 42 completely passes through the adjusting groove 211; after the saw blade 42 enters the adjusting groove 211, the locking member 14 is screwed to abut against the cooperating member 22 to realize the locking of one side of the calibration member 21 to prevent it from shaking, and the clamping block 23 is turned into the fixing seat 13 to limit the reverse rotation of the calibration member 21 to the third direction, i.e. the locking of the other side of the calibration member 21. At this time, the calibration member 21 is fixed relative to the detection table 10.

[0064] Further, in the case that the calibration member 21 is fixed relative to the detection table 10, the fastening bolts between the bottom plate 41 and the driving motor 43 are tightened again; at this time, the relative position between the saw blade 42 and the bottom plate 41 is determined.

[0065] Further, the rotation of the adjusting member 30 will push the base plate 41 of the power tool 400 to move in the first direction 101; at this time, the saw blade 42 has already passed the adjusting slot 211, and the movement of the base plate 41 will cause the relative movement of the saw blade 42 in the adjusting slot 211, until the first end surface 421 of the saw blade 42 completely abuts against the first wall surface 212 of the adjusting slot 211.

[0066] Further, when the first end surface 421 of the saw blade 42 abuts against the first wall surface 212 of the adjusting slot 211, the calibration of the base plate 41 and the saw blade 42 in the current power tool 400 is completed; since the base plate 41 is parallel to the table 15 of the detection table 10, and the calibration member 21 is vertically arranged relative to the table 15 of the detection table 10, thus the first wall surface 212 on the calibration member 21 is vertical relative to the table 15 of the detection table 10; when the first end surface 421 abuts against the first wall surface 212, it is forced that the first end surface 421 is vertical to the table 15 of the detection table 10, that is, the perpendicularity calibration between the first end surface 421 and the horizontal surface 413 on the base plate 41 is completed; similarly, the vertical reference surface 412 of the base plate 41 is parallel to the first wall surface 212, so that the first end surface 421 is parallel to the vertical reference surface 412, that is, the parallelism calibration of the first end surface 421 and the base plate 41 is completed.

[0067] Although the present application has been disclosed as above, the present application is not limited to this. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present application, thus the protection scope of the present application should be subject to the scope defined by the claims.
