[0028] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments: Example 1:

[0029] See also Figures 1-6 , an electric saw chain detection device, the electric chain saw includes a hand-held main body, a guide plate and a saw chain, the guide plate is locked on the hand-held main body by a fastener, the saw chain is sleeved and guided and slidably configured on the guide plate, the hand-held main body drives the saw chain to move on the guide plate, the front end of the guide plate is rotatably configured with a sprocket to guide the saw chain, a hexagonal hole is opened on the center of the sprocket, and the tightness of the saw chain can be adjusted by adjusting the relative position between the guide plate and the hand-held main body.

[0030] The detection device includes a base frame 1, a moving device 2, a pressure measuring device 3 and a detection device 4. The base frame 1 is provided with a positioning member 11, a first locking member 12 and a second locking member 13. The positioning member 11 is used to position the two sides and the front end of the electric chain saw body so that the electric chain saw is placed flat on the base frame 1. The first locking member 12 and the second locking member 13 are both elastic telescopic members. The first locking member 12 and the second locking member 13 are respectively provided with a first inclined surface 121 and a second inclined surface 131. The first locking member 12 cooperates with the bottom surface of the base frame 1 to lock the up and down movement of the handheld main body. The second locking member 13 is located behind the positioned handheld main body, and cooperates with the positioning member 11 to lock the movement of the handheld main body in the front and back directions.

[0031] After the handheld main body on the electric chain saw is positioned and placed on the positioning member 11, the electric chain saw is not in a horizontal state at this time, and is then pressed downward, so that the handheld portion of the handheld main body presses against the first inclined surface 121 of the first locking member 12, thereby causing the first locking member 12 to retract to both sides, causing the handheld main body to move downward. After the handheld main body passes, the first locking member 12 elastically resets, thereby limiting the handheld main body so that it cannot move upward. When the handheld main body is pressed downward, the rear end surface presses against the second inclined surface 131 of the second locking member 13, and the second locking member 13 elastically moves backward. When the handheld main body is locked by the first locking member 12, the front end surface of the second locking member 13 contacts the rear end surface of the handheld main body, thereby causing the front end of the handheld main body to contact the positioning member 11, and the electric chain saw is locked to the base frame 1 through the locking of the first locking member 12 and the second locking member 13.

[0032] The mobile device 2 includes a guide rail frame 21 and a mobile frame 22. The rail frame 21 is fixedly configured on the base frame 1, and a guide groove 211 is opened on the guide rail frame 21. The mobile frame 22 is slidingly configured on the guide groove 211, and the rail frame 21 is parallel to the guide plate of the locked electric chain saw. At the same time, the direction of the guide groove 211 is consistent with the direction in which the guide plate adjusts the tightness of the saw chain. A rack is configured in the guide groove 211, and a power piece is configured on the mobile frame 22. The power piece is a servo motor that can achieve precise angular rotation. A gear is configured on the power piece, which cooperates with the rack on the guide groove 211 to achieve precise position movement. A driving piece 221 is configured on the mobile frame 22, and the driving piece 221 is equipped with a hexagonal driving shaft 222 that can be retracted, wherein the six The angular drive shaft 222 is guided and slidably configured on the driving member 221. The driving member 221 can drive the hexagonal drive shaft 222 to rotate. At the same time, the rear end of the hexagonal drive shaft rotates and is connected to the telescopic rod with an electric telescopic rod. The extension and retraction of the electric telescopic rod drives the hexagonal drive shaft 222 to realize the telescopic movement back and forth on the driving member 221. A positioning through hole is provided on the guide plate, and an infrared sensor is provided on the movable frame 22, wherein the infrared sensor is used to identify the positioning through hole, and then identify the position of the sprocket. The position of the positioning through hole is on the same horizontal line as the hexagonal shaft hole of the sprocket, and the distance between the infrared sensor and the hexagonal drive shaft 222 is consistent with the distance between the hexagonal shaft hole of the sprocket and the positioning through hole. Therefore, when the infrared sensor is located at the center of the positioning through hole, the hexagonal drive shaft 222 is also aligned with the hexagonal shaft hole.

[0033] After the electric saw is locked on the base frame 1, the mobile frame 22 starts to start. At this time, the hexagonal drive shaft 222 is in a retracted state. Therefore, the mobile frame 22 moves on the guide rail frame 21 to the position of the electric saw guide plate. During the movement, after entering the guide plate, the light of the infrared sensor is blocked by the guide plate. When the infrared sensor moves to the position of the positioning through hole, the light is restored to be unobstructed again. At this time, the first signal position point is obtained. When the signal of the infrared sensor disappears again, its position just passes through the positioning through hole. At this time, the second signal position point is obtained. The central control unit analyzes the first signal position point and the second signal position point to calculate the center position of the positioning through hole. The movable frame 22 is positioned, thereby restoring and moving back to the center position. At this time, the hexagonal drive shaft 222 is also aligned with the hexagonal shaft hole, and the driving member 221 starts to rotate, thereby driving the hexagonal drive shaft 222 to start rotating. A chamfer is provided at the front end of the hexagonal drive shaft 222, so the hexagonal drive shaft 222 extends forward during the rotation and extends into the hexagonal shaft hole. At the same time, the connection between the electric telescopic rod and the hexagonal drive shaft 222 is an elastic sliding and rotating connection, which can elastically move relative to each other and rotate, so that when the hexagonal drive shaft 222 is not aligned with the hexagonal shaft hole, the hexagonal drive shaft 222 elastically retracts, and after alignment, it is elastically inserted into the hexagonal shaft hole.

[0034] The pressure measuring device 3 includes an axial roller plate 31 and an identification member 32. The axial roller plate 31 is fixedly arranged on the mobile frame 22 and moves with the mobile frame 22. An axial roller is rotatably arranged on the axial roller plate 31, and the axial roller exceeds the upper end surface of the axial roller plate 31. Therefore, the lower end surface of the saw chain blade is pressed on the axial roller, and a pressure sensor is arranged on the axial roller plate 31. The saw chain presses on the axial roller, and its pressure contact force is transmitted to the pressure sensor, thereby identifying the pressure contact force of the saw chain on the axial roller plate 31.

[0035] When the pressure measuring device 3 is making a prediction, the driving member 221 rotates clockwise, and the saw chain moves via the sprocket, so that the chain above the guide plate is in a tensioned state, while the chain below the guide plate is in a relaxed state.

[0036] When the driving member 221 drives the sprocket to start rotating, the sprocket drives the saw chain to rotate, so the blade passes through the shaft roller plate 31 continuously, and the position of the shaft roller plate 31 relative to the sprocket is fixed. A pressure interval value N0-N1 is set in the central control unit. When the saw chain is too loose, the saw chain sags, so the force of the saw chain pressing on the shaft roller plate 31 will increase. When the pressure contact force is greater than N1, it is necessary to start the detection device 4 to detect the saw chain. Similarly, when the saw chain is too tight, it is completely tightened and pressed against the guide plate. Therefore, when it rotates, when passing through the shaft roller plate 31, there will be a phenomenon that the pressure contact force is reduced or does not contact the shaft roller plate 31. Therefore, when the pressure contact force is less than N0, it is also necessary to start the detection device 4 to detect the saw chain.

[0037] The detection device 4 includes a clamping member 41 and a lifting member 42. The clamping member 41 is a pneumatic clamping member or an electric clamping member equipped with a first clamping plate and a second clamping plate. The first clamping plate and the second clamping plate are in an open state in the initial state and are respectively located on the left and right sides of the saw chain. The front end of the lifting rod of the lifting member 42 is connected to the clamping member 41, which can drive the clamping member 41 to move up and down. The lifting member 42 is fixedly configured on the base frame 1.

[0038] When the pressure measuring device 3 detects that the detection device 4 needs to intervene for detection, the driving member 221 first reverses a certain angle and then stops rotating, thereby tightening the saw chain under the guide bar. At this time, the saw chain under the guide bar is pressed against the lower end surface of the guide bar, and the clamping member 41 begins to close to clamp the saw chain. At the same time, the driving member 221 is powered off, so that the brake of the sprocket is released, the sprocket can rotate, and the lifting member 42 starts to move downward. During the movement, the saw chain is pulled downward. When the downward pulling force of the lifting member 42 on the saw chain reaches a set value, the central control unit identifies the lowering distance L2 of the extending and lowering member 42. A stretching distance range of L0-L1 is preset in the central control unit. By comparing L2 with L0-L1, when L2 is within this range, the chain tightness meets the requirements. When L2 is greater than L1, it is determined that the saw chain is too loose. When L2 is less than L0, it is determined that the saw chain is too tight.

[0039] Its working principle or usage is as follows: The operator positions and locks the electric chain saw on the base frame 1 through the first locking member 12 and the second locking member 13 , and the central control unit controls the moving frame 22 to start.

[0040] Initially, the hexagonal drive shaft 222 is in a retracted state, and the mobile frame 22 moves on the guide rail frame 21 to the position of the electric saw guide plate. When the infrared sensor moves to the position of the positioning through hole, the light is restored to be unobstructed again, and the first signal position point is obtained at this time. When the signal of the infrared sensor disappears again, its position just passes through the positioning through hole, and the second signal position point is obtained at this time. The central control unit analyzes the first signal position point and the second signal position point, calculates the center position of the positioning through hole, and then makes the mobile frame 22 move backward to the center position. At this time, the hexagonal drive shaft 222 is also aligned with the hexagonal shaft hole, and the driving member 221 starts to rotate, thereby driving the hexagonal drive shaft 222 to start rotating, and a chamfer is provided at the front end of the hexagonal drive shaft 222, so the hexagonal drive shaft 222 extends forward during the rotation and is elastically inserted into the hexagonal shaft hole.

[0041] The driving member 221 drives the sprocket to rotate, and the saw chain starts to rotate, so the blade passes through the shaft roller plate 31 continuously, and the position of the shaft roller plate 31 relative to the sprocket is fixed. A pressure interval value N0-N1 is set in the central control unit. When the saw chain is too loose, the saw chain sags, so the force of the saw chain pressing on the shaft roller plate 31 will increase. When the pressure contact force is greater than N1, it is necessary to start the detection device 4 to detect the saw chain. Similarly, when the saw chain is too tight, it is completely tightened and pressed on the guide plate. Therefore, when it rotates, when passing the shaft roller plate 31, there will be a phenomenon that the pressure contact force is reduced or does not contact the shaft roller plate 31. Therefore, when the pressure contact force is less than N0, it is also necessary to start the detection device 4 to detect the saw chain.

[0042] When the pressure measuring device 3 detects that the detection device 4 needs to intervene for detection, the driving member 221 first reverses a certain angle and stops rotating, and then tightens the saw chain under the guide plate. At this time, the saw chain under the guide plate is pressed against the lower end surface of the guide plate, and the clamping member 41 begins to close to clamp the saw chain. At the same time, the driving member 221 is powered off, so that the brake of the sprocket is released, and the sprocket can rotate. The lifting member 42 starts to move downward. During the movement, the saw chain is pulled downward. When the lifting member 42 and the clamping member are in contact with each other, the saw chain is pulled downward. A tension sensor is arranged between 41, which can identify the tension value between the two. When the downward pulling force of the lifting member 42 on the saw chain reaches the set value, the central control unit identifies the downward distance L2 of the extending and lowering member 42. A stretching distance range L0-L1 is preset in the central control unit. By comparing L2 with L0-L1, when L2 is within this range, the tightness of the chain meets the requirements. When L2 is greater than L1, it is determined that the saw chain is too loose. When L2 is less than L0, it is determined that the saw chain is too tight.

[0043] Example 2:

[0044] See also Figures 1-6 This embodiment makes the following further improvements on the basis of embodiment 1: it also includes an adjustment device 5, the adjustment device 5 includes a screwing member 51 and a screwing head 52, the screwing member 51 is arranged on the base frame 1, the screwing member 51 is a screwing motor, and a torque rotating head is arranged on it. The screwing head 52 is arranged on the torque rotating head and is provided with two fasteners for adapting to the two locking guide plates on the handheld body. The screwing member 51 can be telescopically moved back and forth, and then the screwing head 52 is inserted into the fastener to lock or loosen it.

[0045] When the detection device 4 in Example 1 detects that the saw chain is too loose, the screwing member 51 first loosens the fastener to enable the guide plate to move, and the lifting member 42 then rises to the required height, i.e., within L0-L1, and then the movable frame 22 starts to move outward. At this time, the hexagonal drive shaft 222 is located in the hexagonal shaft hole, and then the movable frame 22 moves outward to drive the guide plate to move outward together, thereby tightening the saw chain. At the same time, when the tension value of the tension sensor between the lifting member 42 and the clamping member 41 reaches the set value, the movable frame 22 stops moving outward, and the screwing member 51 rotates in the opposite direction to retighten the fastener.

[0046] When the detection device 4 in Example 1 detects that the saw chain is too tight, the screwing member 51 first loosens the fastener to allow the guide plate to move, and the lifting member 42 rises to the initial 0 position. At the same time, the movable frame 22 first moves backward a set distance to completely relax the chain saw blade. At this time, the lifting member 42 rises again to the required height, that is, within L0-L1, and then the movable frame 22 starts to move outward. The outward movement of the movable frame 22 drives the guide plate to move outward together, thereby tightening the saw chain. At the same time, when the tension value of the tension sensor between the lifting member 42 and the clamping member 41 reaches the set value, the movable frame 22 stops moving outward, and the screwing member 51 rotates in the opposite direction to retighten the fastener.

[0047] In this way, when the detection device 4 detects that the saw chain is too loose or too tight, it can automatically adjust.

[0048] Example 3:

[0049] See also Figures 1-6 This embodiment makes the following further improvements on the basis of embodiment 1 or 2: a flushing member 23 is provided on the movable frame 22 for flushing the blades of the saw chain. Since the openings of the blades of the saw chain are staggered left and right, flushing members 23 are provided on both sides of the saw chain blades, and an identification member 32 is also provided on the shaft roller plate 31 for identifying the opening direction of the blades. The identification member 32 is a pressure touch switch or a visual camera.

[0050] When it is a pressure touch switch, the outer wall of the blade can press the pressure touch switch when passing by, and then identify the opening direction of the blade. The central control unit identifies the opening direction of the blade. The moving speed of the saw chain is fixed, so the central control unit calculates the time when the blade enters the flushing part 23. After the blade enters the flushing part 23, the water pressure of the flushing parts 23 on both sides is controlled. The water pressure in the opening direction is greater than that on the back side, so that the high water pressure can effectively perform high-pressure flushing on the concave cavity of the blade.

[0051] When the identification member 32 is a visual camera, the opening direction of the blade is directly identified by vision at the same time, the water pressure is adjusted, and an effective high-pressure flushing operation is completed.

[0052] At the same time, air blowing ports are provided on the left and right clamping plates of the clamping member 41 , and the air blowing ports are aimed at the saw chain for drying the saw chain.

[0053] When the pressure measuring device 3 detects that the pressure value is within the normal range, the chain flushing and drying operations are started to keep the saw chain clean. At the same time, a water storage chamber 14 and a sewage pool 15 are opened in the base frame 1. The sewage pool 15 is used to store sewage and is located below the flushing part 23. Clean water is stored in the water storage chamber 14, which is connected to the flushing part 23 for flushing the saw chain.

[0054] The movable frame 22 is also provided with a spray nozzle 24. When the entire saw chain is cleaned and dried, the driving member 221 drives the saw chain to rotate. At this time, the spray nozzle 24 starts to work and sprays oil mist to the saw chain.

[0055] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
