[0018] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, the present embodiment proposes an automatic detection device for a saw chain guide slot, comprising a main frame 1, a positioning slot 2 and a slide slot 3. The main frame 1 is provided with a positioning slot 2 inside, and slide slots 3 are provided on both sides of the main frame 1. A fixing mechanism is provided between the slide slot 3 and the main frame 1, and a guide frame 4 is provided on one side of the main frame 1. A moving mechanism is provided on the guide frame 4, and a cylinder 11 is installed on the top of the moving mechanism. The output end of the cylinder 11 is fixedly connected with the detection mechanism, and the saw chain guide is inserted into the interior of the main frame 1 through the positioning slot 2, and the position of the saw chain guide is locked by the fixing mechanism. Then, the output end of the cylinder 11 drives the detection mechanism to move downward, so that the detection mechanism extends into the interior of the saw chain guide slot, and the saw chain guide slot is automatically detected. Then, the moving mechanism drives the detection mechanism to slide inside the saw chain guide slot to detect it in all directions. After that, the cylinder 11 and the moving mechanism drive the detection mechanism to reset, and the saw chain guide is taken out from the interior of the positioning slot 2.

[0020] The fixing mechanism includes a fixing plate 5, a No. 1 threaded rod 6, a groove 7, a clamping plate 8 and a No. 2 threaded rod 9. A fixing plate 5 is provided inside the main frame 1. The fixing plate 5 is symmetrically fixedly connected to the No. 1 threaded rod 6 on both sides. A groove 7 is provided inside the fixing plate 5. The clamping plate 8 is slidably connected inside the groove 7. The top of the fixing plate 5 is threadedly connected to the No. 2 threaded rod 9. The bottom end of the No. 2 threaded rod 9 is rotatably connected to the top of the clamping plate 8. The No. 1 threaded rod 6 is equal in height to the slide groove 3. One end of the No. 1 threaded rod 6 passes through the interior of the slide groove 3 and is threadedly connected to a nut. The positioning groove 2 is parallel to the groove 7 in front and back. The saw chain guide is inserted into the positioning groove 2. After the saw chain guide is inserted into the main frame 1, the nut on the No. 1 threaded rod 6 is first loosened so that the fixing plate 5 can slide linearly along the No. 2 threaded rod 9 to move the fixing plate 5 to one end of the saw chain guide slot. Then, the nut on the No. 1 threaded rod 6 is locked to lock the position of the fixing plate 5. At this time, one end of the saw chain guide passes through the inside of the groove 7. The No. 2 threaded rod 9 is turned to drive the clamping plate 8 to move downward to clamp the saw chain guide to fix the saw chain guide inside the main frame 1 to prevent the detection mechanism from shifting in the saw chain guide slot and affecting the detection result. When the saw chain guide needs to be taken out, the No. 2 threaded rod 9 is turned in the opposite direction to drive the groove 7 to move upward. At this time, the clamping plate 8 is separated from the saw chain guide and is no longer clamped.

[0021] The moving mechanism includes a connecting frame 10, a slider 14, a screw rod 15 and a motor 16. The guide frame 4 is slidably connected with the slider 14. The top of the slider 14 is fixedly connected with the connecting frame 10. The top of the connecting frame 10 is fixedly connected to the outer side of the cylinder 11. The inner side of the guide frame 4 is rotatably connected with the screw rod 15. A motor 16 is installed on one side of the guide frame 4. The output end of the motor 16 is fixedly connected to one end of the screw rod 15. One end of the screw rod 15 passes through the interior of the slider 14 and is threadedly connected thereto. One end of the motor 16 drives the screw rod 15 to rotate on the guide frame 4. The screw rod 15 is threadedly matched with the slider 14, and the guide frame 4 limits the moving trajectory of the slider 14. The screw rod 15 can drive the slider 14 to move linearly back and forth on the guide frame 4 while rotating forward and backward. The slider 14 is fixed to the cylinder 11 through the connecting frame 10, and the output end of the cylinder 11 is fixed to the detection mechanism, so the slider 14 can drive the detection mechanism to slide in the saw chain guide groove for automatic measurement.

[0022] A length gauge is provided on the side of the main frame 1 away from the guide frame 4, and an extension block is provided on one side of the fixed plate 5. One end of the extension block is fitted and connected to the length gauge. By observing the length gauge, the moving distance of the fixed plate 5 can be made more accurate, so that people can move the fixed plate 5 to the set position in advance, thereby enabling people to better clamp the saw chain guide.

[0023] The detection mechanism includes a lifting arm 12 and a pressure measuring ring 13. The output end of the cylinder 11 is fixedly connected to the lifting arm 12, and the bottom end of the lifting arm 12 is fixedly connected to the pressure measuring ring 13. The width of the pressure measuring ring 13 is equal to the width of the standard saw chain guide slot. The pressure measuring ring 13, the positioning groove 2 and the groove 7 are on the same center line. The output end of the cylinder 11 is connected to the pressure measuring ring 13 through the lifting arm 12. The cylinder 11 can drive the pressure measuring ring 13 to move up and down through the lifting arm 12, and drive the bottom end of the pressure measuring ring 13 to insert into the saw chain guide slot. The outer wall of the bottom end of the pressure measuring ring 13 will contact the inner wall of the saw chain guide slot. The pressure measuring ring 13 uses the resistance material as a sensor, and measures the pressure by measuring the change in resistance of the conductive material after being pressurized. The pressure change will cause the electronic structure inside the resistance material to change, thereby affecting the resistance value. The sensor is responsible for detecting the pressure change and transmitting the signal to the external display, and the external display displays the pressure value in digital or graphical form.

[0024] One side of the positioning groove 2 is fixedly connected to a limit plate 17, and both sides of the limit plate 17 are fixedly connected to bolts 18. A rotating rod 19 is sleeved on the outer side of the limit plate 17, and a nut is threadedly connected to the top of the bolt 18. One end of the saw chain guide is placed on the limit plate 17, and then the nut on the top of the bolt 18 is loosened so that it no longer clamps the rotating rod 19. One end of the rotating rod 19 is rotated to fit the outer side of the saw chain guide, and then the nut on the top of the bolt 18 is tightened. The bolt 18 clamps the rotating rod 19 to lock the position of the saw chain guide.

[0025] The automatic detection device for the saw chain guide slot, after inserting the saw chain guide into the interior of the positioning groove 2, first loosen the nut on the No. 1 threaded rod 6 so that the fixing plate 5 can slide linearly along the No. 2 threaded rod 9 to move the fixing plate 5 to one end of the saw chain guide slot, and then lock the nut on the No. 1 threaded rod 6 to lock the position of the fixing plate 5. At this time, one end of the saw chain guide passes through the interior of the groove 7, and the No. 2 threaded rod 9 is screwed to drive the clamping plate 8 to move downward to clamp the saw chain guide to fix the saw chain guide in the main frame 1. The output end of the cylinder 11 is connected to the pressure measuring ring 13 through the lifting arm 12. The cylinder 11 can drive the pressure measuring ring 13 to move up and down through the lifting arm 12, driving the bottom end of the pressure measuring ring 13 to be inserted into the saw chain guide slot, and the outer wall of the bottom end of the pressure measuring ring 13 will contact the inner wall of the saw chain guide slot and transmit the signal to the external display, and the external display will display the pressure value in digital or graphical form to automatically detect the saw chain guide slot.
