DETAILED DESCRIPTION

[0027] The technical solution of the present invention will be further described in detail below in conjunction with specific implementation methods.

[0028] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0029] A chain saw guide plate flatness detection device, such as Figure 1-8 As shown, it includes a conveying frame 1, on which a chain conveyor belt 5 for conveying a chain saw guide plate 8 is installed.

[0030] In this embodiment, a plurality of equally spaced auxiliary conveying components are provided on the chain conveyor belt 5 , and a detection mechanism is provided on the movement path of the auxiliary conveying components.

[0031] The detection mechanism includes a mounting frame 2, a first mounting tube 32, a cross bar 91, a second mounting tube 36, a slide bar 35, a first distance measuring head 30 and a second distance measuring head 38, wherein the distance measuring head can be a laser distance measuring head.

[0032] Among them, a first mounting tube 32 is fixed on the mounting frame 2 through a bracket, a cross bar is installed on one side of the first mounting tube 32, and the second mounting tube 36 slides horizontally on the outer wall of the cross bar. As one option, a second mounting tube 36 is arranged on the left and right sides of the first mounting tube 32 respectively.

[0033] A corresponding sliding rod 35 is disposed on each of the first mounting tube 32 and the second mounting tube 36 , that is, the sliding rod 35 slides up and down on the inner wall of the first mounting tube 32 and the second mounting tube 36 .

[0034] A ball seat 33 is mounted on the slide bar 35 , and a rolling ball 31 is movably mounted in the ball seat 33 so that the rolling ball 31 can roll without falling off the ball seat 33 .

[0035] A slide rod spring 34 is mounted on the slide rod 35 , one end of the slide rod spring 34 abuts against the first mounting tube 32 or the second mounting tube 36 (i.e., the slide rod spring 34 on the slide rod installed at the first mounting tube 32 abuts against the first mounting tube 32 , and the same is true for the second mounting tube 36 ), and the other end abuts against the flange on the outer wall of the slide rod 35 or the extended wall on the ball seat 33 .

[0036] The first distance measuring head 30 can be specifically installed on the flange of the sliding rod 35 or on an extension arm fixed on the flange.

[0037] The second distance measuring heads 38 are respectively mounted on the outer wall of one side of the first mounting tube 32 and the second mounting tube 36 , that is, the first mounting tube 32 and the second mounting tube 36 are respectively mounted with corresponding second distance measuring heads 38 .

[0038] The second distance measuring head 38 and the first distance measuring head 30 are staggered, and the line connecting the detection points of the second distance measuring head 38 and the first distance measuring head 30 is parallel to or consistent with the movement direction of the chain saw guide bar 8 .

[0039] The second distance measuring head 38 can be specifically arranged on an extension arm on the corresponding mounting tube, and the extension arm on the mounting tube is longer than the extension arm on the slide bar flange, so that the second distance measuring head 38 detects the chain saw guide bar before the first distance measuring head 30.

[0040] In this embodiment, a slide rail 29 is also installed on the mounting frame 2, and an adaptable slide plate 3 is slidably connected inside the slide rail 29. The adaptable slide plate 3, the second mounting cylinder 36 and the first mounting cylinder 32 are connected by a transverse spring 37. A guide head 7 is integrally provided at one end of the adaptable slide plate 3.

[0041] As for the auxiliary conveying component, it includes a carrier 10 and a clamping component, wherein the carrier 10 is installed on the chain of the chain conveyor belt 5, the clamping component is installed on the carrier 10, and a vertical roller 12 is installed at the outer end of the clamping component, and the guide head 7 and the adaptive skateboard 3 are located on the movement path of the vertical roller 12.

[0042] By setting up the detection mechanism, the chain saw guide plate 8 to be detected can be placed on the carrier 10 and fixed with the assistance of the clamping component. The chain saw guide plate 8 can be transported based on the operation of the chain conveyor belt 5.

[0043] Since the detection mechanism is on the conveying path, as the conveying proceeds, the ball 31 slides to the top surface of the chain saw guide 8 and maintains close contact with the top surface of the chain saw guide 8 based on the force of the slide spring 34. If the chain saw guide 8 has poor flatness such as deformation, the slide 35 moves upward based on the reaction force, thereby changing the position of the first ranging head 30.

[0044] The second ranging head 38 detects the flatness of the top surface of the chainsaw guide 8 by measuring the distance; and the first ranging head 30 can eliminate measurement errors caused by abnormal situations. For example, if there is a foreign object on the chainsaw guide 8, causing the second ranging head 38 to detect an abnormal value, as the conveying proceeds, since the line connecting the detection point of the second ranging head 38 and the detection point of the first ranging head 30 is parallel to the movement direction of the chainsaw guide 8, the foreign object is immediately detected by the first ranging head 30, and there is a second detection abnormality. If the conveying continues, the foreign object is pushed away by the ball 31, and the ball 31 slides on the same horizontal plane, then there will be no third detection abnormality.

[0045] The controller receives and determines the data detected by the ranging head and whether the slider moves longitudinally within the set threshold time range. For details related to the controller, please refer to the existing design and will not be described in detail.

[0046] If the chainsaw guide bar 8 itself is deformed, after the second distance measuring head 38 and the first distance measuring head 30 detect the abnormality, the ball 31 slides to the deformed position of the chainsaw guide bar 8, causing the height to change, resulting in a height change of the first distance measuring head 30. At this time, based on the numerical change of the first distance measuring head 30, a third detection abnormality is achieved, and it can be determined that the flatness is unqualified.

[0047] The present invention provides structures such as the adaptive slide plate 3 and the guide head 7, taking into account the different widths of chain saw guide plates 8 of different specifications, so that the position of the vertical roller 12 at the outer end can be changed accordingly when clamped by the clamping assembly.

[0048] As the conveying proceeds, the vertical roller 12 contacts the guide head 7, pushing the adaptive slide 3 outward, so that under the traction of the transverse spring 37, the distance between the two second mounting cylinders 36 and the first mounting cylinder 32 changes, thereby achieving adaptive adjustment and making the detection points more evenly distributed, that is, the wider the chain saw guide plate 8, the farther the detection points are distributed, and the narrower the chain saw guide plate 8, the closer the detection points are distributed.

[0049] In order to facilitate the clamping and fixing of the chain saw guide plate 8, as shown in FIG. Figure 2As shown, there are two symmetrically arranged clamping assemblies, the clamping assembly includes a base 22 and a clamping plate 20, the base 22 is fixed on the carrier 10, a clamping slide 16 is fixed on one side of the clamping plate 20, the clamping slide 16 slides on the base 22, the clamping plate 20 and the base 22 are connected by a clamping spring 21, and the vertical roller 12 is fixed to the top of the end of the clamping slide 16 away from the clamping plate 20. By setting the clamping assembly, the chain saw guide 8 can be effectively clamped.

[0050] In order to facilitate operation, the clamping plate 20 can be automatically clamped after the chain saw guide plate 8 is installed. Figure 4 As shown, the inner wall of the carrier 10 is connected to a sliding column 19 for sliding up and down, and the top of the sliding column 19 is exposed above the carrier 10. A sliding cavity 101 is provided in the carrier 10. A tooth plate 13 is fixed to the bottom end of the sliding column 19. The tooth plate 13 slides up and down in the sliding cavity 101. The bottom of the tooth plate 13 and the bottom inner wall of the sliding cavity 101 are connected by a clamping spring 26.

[0051] In this embodiment, the tooth plate 13 is provided with evenly distributed protruding teeth, and a locking tooth block 25 is installed on the clamping slide 16. Under the action of the clamping spring 26, the protruding teeth of the tooth plate 13 limit the locking tooth block 25 in one direction. When the locking tooth block 25 is limited in one direction, it cannot move in the direction close to the slide post 19. When the slide post 19 is pressed into the carrier 10, the one-way limit of the protruding teeth of the tooth plate 13 on the locking tooth block 25 is released.

[0052] By providing the slide column 19 and the tooth plate 13, the convex teeth can be used to limit the tooth block 25 before the chain saw guide 8 is placed, so that the clamping plates 20 on both sides can maintain a wider distance to facilitate the placement of the chain saw guide 8. After the chain saw guide 8 is placed, the slide column 19 is squeezed downward into the carrier 10 to release the limit of the tooth block 25. At this time, based on the force of the clamping spring 21, the chain saw guide 8 is clamped and fixed by the clamping plate 20.

[0053] In order to prevent the slide column 19 from exerting an upward force to affect the test accuracy of the chain saw guide plate 8, Figure 3 、 Figure 4 As shown, limit frames 17 are fixed on both sides of the tooth plate 13, and the height of the limit frames 17 gradually increases towards the direction close to the slide post 19. Limit wheels 24 are rotatably installed on both sides of the tooth block 25. The limit frames 17 are located on the movement path of the limit wheels 24. When the tooth block 25 is limited, the distance between the bottom surface of the limit wheel 24 and the top surface of the limit frame 17 is greater than the height of the protruding teeth of the tooth plate 13, and at the same time greater than the height of the slide post 19 extending from the top surface of the carrier 10.

[0054] By setting the limiting wheel 24 and the limiting frame 17, when the chain saw guide 8 presses the slide 19 into the carrier 10, the limiting of the tooth block 25 is released, and the clamping plate 20 moves based on the force of the clamping spring 21. During the process, the limiting wheel 24 rolls along the top of the limiting frame 17 to press the limiting frame 17 downward. When the clamping plate 20 clamps the chain saw guide 8, the limiting wheel 24 can limit the limiting frame 17 to avoid the top surface of the slide 19 from contacting the bottom surface of the chain saw guide 8, thereby preventing the slide 19 from lifting the chain saw guide 8, thereby ensuring the reliability of the detection.

[0055] In order to facilitate the limiting and fixing of the clamping plate 20 after clamping, as shown in FIG. Figure 3 、 Figure 4 、 Figure 5 As shown, the top outer wall of the base frame 22 is slidably connected to a clamping frame 15, and the clamping frame 15 and the base frame 22 are connected by a clamping spring 23. Guide frames are provided on both sides of the clamping plate 20, and a pressure column 18 is slidably connected up and down in the guide frame. Anti-slip pads 14 are installed on both sides of the top of the carrier 10, and the anti-slip pads 14 are located below the pressure column 18; the pressure column 18 is located below the clamping frame 15, and the pressure column 18 and the guide frame are connected by a reset spring 27.

[0056] By setting up structures such as the compression frame 15, the compression frame 15 can press the pressure column 18 downward based on the force of the compression spring 23, and the bottom surface of the pressure column 18 is in contact with the top surface of the anti-slip pad 14 to achieve the limiting fixation of the pressure column 18, thereby achieving the limiting fixation of the clamping plate 20 and ensuring the firmness of the clamping.

[0057] In order to facilitate the insertion of the chain saw guide plate 8, Figure 1 、 Figure 2 As shown, the conveyor frame 1 is equipped with a first lifting guide plate 9 through a first support rod at the loading station. The two ends of the first lifting guide plate 9 are inclined structures with gradually decreasing heights. A lifting wheel 11 is rotatably installed on one side of the clamping frame 15, and the first lifting guide plate 9 is located on the movement path of the lifting wheel 11.

[0058] By setting the first lifting guide plate 9 and the lifting wheel 11, the clamping frame 15 can remain in a lifted state when the chain saw guide plate 8 is installed to avoid squeezing the pressure column 18, so that the clamping plate 20 can be clamped freely. When the structure leaves the loading station, the lifting wheel 11 disengages from the first lifting guide plate 9, and can timely clamp and fix the pressure column 18 based on the force of the compression spring 23.

[0059] The progress coefficient of the compression spring 23 should be significantly greater than the progress coefficient of the return spring 27 , so as to ensure that a stable and reliable pressure is applied.

[0060] In order to facilitate stable support, such as Figure 5As shown, a guide platform 6 is provided at the front side of the movement path of the carrier 10 , and the top surface of the guide platform 6 is flush with the top surface of the carrier 10 .

[0061] By providing the guide platform 6 , the top of the chain saw guide plate 8 can be supported when the chain saw guide plate 8 is installed, thereby ensuring the reliability of the detection.

[0062] In order to better guide the ball 31, Figure 5 As shown, a sloped platform is integrally provided on one side of the guide platform 6 , and the height of the top of the sloped platform is higher than the height of the top surface of the chain saw guide plate 8 when it is installed on the carrier 10 .

[0063] By providing the inclined platform, the rolling ball 31 can be guided and lifted by the inclined platform when the rolling ball 31 rolls, so that the rolling ball 31 can smoothly roll to the top surface of the chain saw guide plate 8 .

[0064] In order to facilitate cutting, Figure 8 As shown, it also includes a reset mechanism, which includes a dial plate 28. The conveyor frame 1 is equipped with a second lifting guide plate 4 through a second support rod at the unloading station. The shape of the second lifting guide plate 4 is the same as that of the first lifting guide plate 9. The second lifting guide plate 4 is located on the movement path of the lifting wheel 11. The dial plate 28 is installed on the second support rod. The two dial plates 28 are symmetrically arranged. The dial plate 28 is located on the movement path of the vertical roller 12.

[0065] By setting the second lifting guide plate 4 and the dial plate 28, when the structure moves to the unloading station, the second lifting guide plate 4 can be used to lift the lifting wheel 11 upward, so that the pressure column 18 is reset upward based on the reset spring 27, thereby unlocking the clamping plate 20. As the conveying progresses, the vertical roller 12 contacts the dial plate 28 and is guided by the dial plate 28, so that the two vertical rollers 12 move to both sides, synchronously driving the two clamping plates 20 to loosen the chain saw guide 8. The sliding column 19 and the tooth plate 13 are reset based on the rebound force of the clamping spring 26, and the chain saw guide 8 is lifted up. The convex teeth of the tooth plate 13 again limit the tooth block 25 in one direction. As the conveying progresses, the vertical roller 12 disengages from the dial plate 28. Because the tooth block 25 is limited, the clamping plate 20 remains in place to facilitate the next clamping operation.

[0066] A method for detecting the flatness of a chain saw guide bar comprises the following steps: S1: Install the chain saw guide plate 8 into the carrier 10 at the loading station, and apply force to press the slide post 19 downward into the carrier 10 .

[0067] S2: The restriction of the tooth block 25 is released, the clamping plate 20 clamps the chain saw guide plate 8, and at the same time the limiting wheel 24 restricts the tooth plate 13 and the sliding column 19 from moving upward.

[0068] S3: The chain conveyor belt 5 conveys the chain saw guide plate 8. When the lifting wheel 11 separates from the first lifting guide plate 9, it presses the pressure column 18 downward to limit and fix the pressure column 18 and the clamping plate 20.

[0069] S4: As the chain conveyor belt 5 is conveyed, the vertical roller 12 contacts the guide head 7 and the adaptive slide 3, and based on the traction of the transverse spring 37, the distance between the second mounting cylinder 36 and the first mounting cylinder 32 is adjusted.

[0070] S5: The chain saw guide bar 8 is transported to the inspection station and inspected by the second distance measuring head 38 and the first distance measuring head 30 (the specific inspection method and inspection result judgment are described above).

[0071] S6: After the detection is completed, based on the transportation of the chain conveyor belt 5, the lifting wheel 11 is lifted again by the second lifting guide plate 4, and the vertical roller 12 is pushed to both sides by the shift plate 28, which facilitates the unloading of the chain saw guide plate 8 and realizes the reset of the structure at the same time.

[0072] For the parts of the present invention that are not fully disclosed, those skilled in the art can ensure that the solutions of the present invention are successfully implemented based on common sense, normal thinking logic and existing technologies.

[0073] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
