Description

Technical Field

[0001] This invention relates to the field of air conditioning, and more specifically, to a device and method for detecting the curvature of an air conditioning gear rack. Background Technology

[0002] In the existing technology, a gear rack is installed on the sliding door assembly of the indoor unit of an air conditioner, which drives the opening and closing of the sliding door. Because the gear rack is arc-shaped and irregular in shape, conventional testing tools have low detection accuracy and slow detection speed, and cannot accurately detect whether the arc of the gear rack meets the standard. If a substandard gear rack is installed in the air conditioner, it will cause the sliding door to run poorly or get stuck during operation, resulting in a poor user experience. Summary of the Invention

[0003] The problem solved by this invention is that, in the prior art, conventional tools for detecting the curvature of gear racks have low detection accuracy and slow detection speed, and cannot accurately detect whether the curvature of the gear rack meets the standards.

[0004] To address the aforementioned problems, this invention discloses a device for detecting the curvature of an air conditioning gear rack. The device includes a detection base plate, on which a first detection part, a gear tooth meshing part, and a second detection part are disposed. The gear tooth meshing part is located between the first and second detection parts. A first arc-shaped groove is provided on the first detection part, which engages with a first arc-shaped plate on the gear rack. A second gear tooth is provided on the gear tooth meshing part, and the second gear tooth engages with the first gear tooth on the gear rack. A second arc-shaped groove is provided on the second detection part, which engages with a second arc-shaped plate on the gear rack. The second detection part is movably disposed relative to the gear tooth meshing part.

[0005] With the above setup, during testing, the first arc-shaped plate is first inserted into the first arc-shaped groove, then the second gear tooth is meshed with the first gear tooth, and finally the second detection unit is moved towards the gear tooth meshing part. The curvature of the gear rack being tested is determined based on the fit between the second arc-shaped groove and the second arc-shaped plate. During testing, if the gear rack's curvature meets the standard, the first arc-shaped groove and the first arc-shaped plate, the first gear tooth and the second gear tooth, and the second arc-shaped groove and the second arc-shaped plate can be easily positioned, allowing the first detection unit, the gear tooth meshing part, and the second detection unit to clamp the gear rack. The test is successfully completed, and the curvature of the inspected gear rack is determined to be up to standard. If the curvature of the gear rack is not up to standard, since the gear rack is a long strip structure, the operator can easily deform it to ensure that the first arc plate enters the first arc groove. At this time, the side of the gear rack that is not positioned will warp and deform, and the second gear tooth will have difficulty meshing with the first gear tooth. When the second detection part is moved towards the gear tooth meshing part, the second arc plate will interfere with the second detection body of the second detection part, and it will not be able to enter the second arc groove smoothly. Therefore, it can be determined that the curvature of the currently inspected gear rack is not up to standard.

[0006] Furthermore, mating detection parts are provided on the left and right sides of the gear tooth meshing part, and the mating detection parts are used to detect whether the second detection part abuts against the gear tooth meshing part.

[0007] When the curvature deviation of the gear rack under inspection is small, the warping deformation of the first gear tooth and the second arc plate is low. The second arc plate can partially enter the second arc groove, but due to the warping deformation, it cannot fully enter. The second detection part cannot abut against the meshing part of the gear tooth. Since there are other mating and mounting structures on the gear rack, the insertion of the second arc plate into the second arc groove and the abutment of the second detection part against the meshing part of the gear tooth are somewhat obscured. This situation is difficult to distinguish with the naked eye. It is necessary to set up a mating detection part for further inspection in order to more accurately detect whether the curvature of the gear rack under inspection meets the standard.

[0008] Furthermore, the mating detection unit includes a first detection platform with a first positioning hole, and a second detection platform with a second positioning hole at each of the left and right ends of the second detection unit. The second positioning hole is a through hole. When the second detection unit abuts against the gear meshing part, the first positioning hole and the second positioning hole are coaxially arranged.

[0009] This setup helps to observe the alignment of the first positioning hole and the second positioning hole, thereby determining the fit between the second arc plate and the second arc groove based on the alignment. When the fit is poor, the second detection part cannot abut against the gear meshing part, and the first positioning hole and the second positioning hole cannot be aligned, making it easy to determine that the curvature of the currently inspected gear rack is substandard.

[0010] Furthermore, the detection device also includes a detachable pin, which is used to detect whether the first positioning hole and the second positioning hole are aligned.

[0011] This setting can quickly determine whether the curvature of the gear rack under inspection meets the standard by observing the insertion of the pin, which is simple and fast, and greatly improves the detection speed and accuracy.

[0012] Furthermore, a moving device is provided on the detection substrate. The moving device is connected to the second detection unit and is used to drive the second detection unit closer to or away from the gear meshing part.

[0013] The moving device is configured to drive the second detection unit to move. When it drives the second detection unit away from the gear meshing part, it can provide sufficient space for the operator to mate the rack to be inspected with the first detection unit and the gear meshing part. After the rack is mated, the moving device drives the second detection unit to move toward the gear meshing part to complete the inspection.

[0014] Furthermore, the moving device includes a guide rail and a slider, the guide rail being slidably connected to the slider, and the slider being fixedly connected to the second detection unit.

[0015] As the slider moves along the guide rail, it simultaneously drives the second detection unit to move closer to or away from the gear meshing part.

[0016] Furthermore, there are two guide rails, and each guide rail is equipped with a slider.

[0017] When only one guide rail is set, the second detection part is prone to some deviation during movement due to the gap between the slider and the guide rail, which will affect the detection accuracy of the detection device to a certain extent. The setting of two guide rails can effectively curb the deviation of the second detection part, thereby ensuring the detection accuracy of the detection device. Of course, three or more guide rails can improve the detection accuracy to a certain extent, but will make the structure of the detection device more complex and will also affect the smoothness of the sliding of the second detection part.

[0018] Furthermore, a limiting structure is provided at the end of the guide rail away from the gear meshing part, the limiting structure being used to limit the movement stroke of the slider.

[0019] When the limiting structure can prevent the slider from disengaging from the guide rail, thereby restricting the travel of the second detection unit, when the slider abuts against the limiting structure, the second detection unit is away from the gear meshing part, and there is sufficient space between them to set the gear rack to be detected.

[0020] This invention also discloses a method for detecting the curvature of an air conditioning gear rack, used in the air conditioning gear rack curvature detection device described above, the detection method comprising:

[0021] Step S1: Move the second detection unit away from the gear meshing part;

[0022] Step S2: Connect the first arc-shaped plate on the gear rack under test to the first arc-shaped groove;

[0023] Step S3: Engage the first gear tooth on the gear rack under test with the second gear tooth;

[0024] Step S4: Move the second detection unit close to the moving gear meshing part;

[0025] Step S5: Connect the second arc-shaped plate on the gear rack under test to the second arc-shaped groove;

[0026] Step S6: Determine whether the curvature of the gear rack under test meets the standard based on the fit and insertion of the second arc plate and the second arc groove.

[0027] When the curvature of the gear rack under test meets the standard, the first arc-shaped plate and the first arc-shaped groove, and the second arc-shaped plate and the second arc-shaped groove, are fully engaged. The first gear teeth and the second gear teeth are fully meshed. The first and second detection units clamp the gear rack under test on the meshing part of the gear teeth. When the curvature of the gear rack under test does not meet the standard, when the first arc-shaped plate is engaged with the first arc-shaped groove, the gear rack will warp and deform, affecting the subsequent meshing of the first and second gear teeth and the engagement of the second arc-shaped plate with the second arc-shaped groove. When the curvature deviation is large, the second arc-shaped plate abuts against the second detection body of the second detection unit and cannot engage with the second arc-shaped groove at all. When the curvature deviation is small, the second arc-shaped plate can barely engage with the second arc-shaped groove, but cannot abut against the bottom of the second arc-shaped groove, causing the second detection unit to be unable to abut against the meshing part of the gear teeth. It can also be determined that the curvature of the gear rack under test does not meet the standard.

[0028] Furthermore, a first detection platform is provided on the left and right sides of the gear meshing part, and a first positioning hole is provided on the first detection platform. A second detection platform is provided at both ends of the second detection part, and a second positioning hole is provided on the second detection platform. The second positioning hole is a through hole. The detection device also includes a pin. Step S6 includes:

[0029] Step S61: Insert the pin into the second positioning hole, and determine whether the arc of the gear rack being tested meets the standard based on the insertion of the pin;

[0030] Step S62: When the pin can pass through the second positioning hole and be inserted into the first positioning hole, it is determined that the curvature of the current gear rack under inspection meets the standard; when the pin cannot enter the first positioning hole, it is determined that the curvature of the current gear rack under inspection does not meet the standard.

[0031] The alignment of the second arc plate and the second arc groove is determined. When the alignment is poor, the second detection part cannot abut against the meshing part of the gear teeth, and the first positioning hole and the second positioning hole cannot be aligned. It can be easily determined that the curvature of the gear rack under inspection is not up to standard. When the pin can pass through the second positioning hole and enter the first positioning hole, it means that the second detection part abuts against the meshing part of the gear teeth, and the curvature of the gear rack under inspection is up to standard. The whole inspection process is simple and convenient, and can accurately determine whether the curvature of the gear rack under inspection is up to standard.

[0032] Compared with existing technologies, the air conditioning gear rack arc detection device and method described in this invention have the following advantages:

[0033] This invention, through the arrangement of a first detection unit, a gear meshing unit, and a second detection unit, clamps the gear rack between the first and second detection units during testing. The fit between the second positioning groove on the second detection unit and the second arc-shaped plate on the gear rack determines whether the gear rack's curvature meets the standard. This results in high detection accuracy and speed, significantly improving the precision of gear rack testing. The invention also features a simple structure and convenient operation, greatly enhancing the accuracy and efficiency of detecting whether the gear rack's curvature meets the standard.

Detailed Implementation

[0045] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the described embodiments are only some, not all, of the embodiments of this invention. The specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0046] like Figure 8 , Figure 9 As shown, the gear rack 9 includes a first gear tooth 91, a first arc plate 92, and a second arc plate 93. The first gear tooth 91, the first arc plate 92, and the second arc plate 93 are all arc-shaped and maintain the same curvature. Normally, the gear rack 9 is driven by the meshing of the first gear tooth 91 with the gear to open and close the air conditioner door assembly. The detection device in the prior art cannot accurately detect whether its curvature meets the standard, which leads to potential hazards in the use of the entire air conditioner.

[0047] The following describes in detail, with reference to the accompanying drawings, an embodiment of the present invention, a device and method for detecting the curvature of an air conditioning gear rack.

[0048] Example 1

[0049] This embodiment provides a device for detecting the curvature of an air conditioning gear rack, such as... Figures 1-9As shown, the detection device for detecting the curvature of a gear rack 9 includes a detection base plate 1. A first detection part 2, a gear tooth meshing part 3, and a second detection part 4 are disposed on the detection base plate 1. The gear tooth meshing part 3 is disposed between the first detection part 2 and the second detection part 4. A first arc-shaped groove 22 is provided on the first detection part 2, which engages with a first arc-shaped plate 92 on the gear rack 9. A second gear tooth 32 is provided on the gear tooth meshing part 3, which engages with a first gear tooth 91 on the gear rack 9. A second arc-shaped groove 42 is provided on the second detection part 4, which engages with a second arc-shaped plate 93 on the gear rack 9. The second detection part 4 is movably disposed relative to the gear tooth meshing part 3. It should be understood that the first arc-shaped groove 22 is adapted to the arc and shape of the first arc-shaped plate 92 to ensure that the first arc-shaped plate 92 of the gear rack 9 with the required arc can be smoothly inserted. The second gear tooth 32 is adapted to the arc and shape of the first gear tooth 91 to ensure that the first gear tooth 91 of the gear rack 9 with the required arc can mesh smoothly. The second arc-shaped groove 42 is adapted to the arc and shape of the second arc-shaped plate 93 to ensure that when the second detection part 4 moves close to the gear meshing part 3, the second arc-shaped plate 93 can be smoothly inserted into the second arc-shaped groove 42. In addition, when the... When the second detection unit 4 approaches the gear meshing part 3 and finally abuts against the gear meshing part 3, the positional relationship of the first arc groove 22, the second gear tooth 32, and the second arc groove 42 corresponds one-to-one with the positional relationship of the first arc plate 92, the first gear tooth 91, and the second arc plate 93. Therefore, when a gear rack 9 with a qualified arc is detected, the first arc plate 92 is inserted into the first arc groove 22, the first gear tooth 91 meshes with the second gear tooth 32, and the second arc plate 93 is inserted into the second arc groove 42, at the same time, the second detection unit 4 abuts against the gear meshing part 3.With the above setup, during testing, the first arc plate 92 can be inserted into the first arc groove 22 first, then the second gear tooth 32 can be engaged with the first gear tooth 91, and finally the second detection unit 4 can be moved towards the gear tooth engagement part 3. The curvature of the rack 9 being tested can be determined based on the fit between the second arc groove 42 and the second arc plate 93. If the curvature of the rack 9 meets the standard during testing, the first arc groove 22 and the first arc plate 92, the first gear tooth 91 and the second gear tooth 32, and the second arc groove 42 and the second arc plate 93 can be easily positioned, allowing the first detection unit 2, the gear tooth engagement part 3, and the second detection unit 4 to clamp the rack 9, thus successfully completing the testing. The system measures the curvature of the rack 9 under inspection to determine if it meets the standard. If the curvature of the rack 9 does not meet the standard, because the rack 9 is a long strip structure, the operator can easily deform it to ensure that the first arc plate 92 enters the first arc groove 22. At this time, the side of the rack 9 that is not positioned will warp and deform, making it difficult for the second gear tooth 32 to mesh with the first gear tooth 91. When the second detection part 4 is moved towards the gear meshing part 3, the second arc plate 93 will interfere with the second detection body 41 of the second detection part 4, preventing it from smoothly entering the second arc groove 42. Consequently, the second detection part 4 and the gear meshing part 3 cannot abut, thus determining that the curvature of the rack 9 under inspection does not meet the standard. This setting can accurately detect whether the curvature of the rack 9 meets the standard, greatly improving the accuracy and efficiency of the detection. Specifically, the first detection unit 2 includes a first detection body 21, and the first arc-shaped groove 22 is disposed on the first detection body 21. The second detection unit 4 includes a second detection body 41, and the second arc-shaped groove 42 is disposed on the second detection body 41. The gear meshing part 3 includes a meshing part body 31, and the second gear tooth 32 is disposed at the top end of the meshing part body 31.

[0050] As one embodiment of the present invention, such as Figure 1 , Figure 2 , Figure 4As shown, mating detection parts 7 are provided on the left and right sides of the gear meshing part 3. These mating detection parts 7 are used to detect the mating condition of the second arc-shaped plate 93 and the second arc-shaped groove 42, or to detect whether the second detection part 4 abuts against the gear meshing part 3. As described above, the detection device provided in this embodiment mainly determines whether the curvature of the gear rack 9 meets the standard based on the mating condition of the second arc-shaped plate 93 and the second arc-shaped groove 42. When the curvature deviation of the gear rack 9 is large, the second arc-shaped plate 93 interferes with the second detection part 4, and the second arc-shaped plate 93 cannot enter the second arc-shaped groove 42 at all. In this case, the operator can visually determine that the curvature of the gear rack 9 under inspection does not meet the standard. However, when the curvature deviation of the gear rack 9 under inspection is small, the warping deformation of the first gear tooth 91 and the second arc-shaped plate 93 is low, and the second arc-shaped plate 93 can partially enter the second arc-shaped groove 42. However, due to warping deformation, it cannot fully enter. The second detection unit 4 also cannot abut against the gear meshing part 3. Since other mating structures are provided on the gear rack 9, the insertion of the second arc plate 93 and the second arc groove 42, as well as the abutment of the second detection unit 4 and the gear meshing part 3, are somewhat obscured. This situation is difficult to distinguish with the naked eye, so a mating detection unit 7 is needed for further detection in order to more accurately detect whether the curvature of the gear rack 9 meets the standard. Therefore, the setting of the mating detection unit 7 can further improve the detection accuracy of the curvature compliance of the gear rack 9. As an optional embodiment, the mating detection unit 7 can be a feeler gauge, a crimping indicator light that lights up when abutting, or other components that facilitate the detection of insertion or abutment.

[0051] As an optional embodiment, such as Figure 3 Figure 4 As shown, the mating detection unit 7 includes a first detection platform 71 with a first positioning hole 72. Second detection platforms 43 are located at the left and right ends of the second detection unit 4, with second positioning holes 431 on each platform. The second positioning holes 431 are through holes. When the second detection unit 4 abuts against the gear meshing part 3, the first positioning hole 72 and the second positioning hole 431 are coaxially aligned. Specifically, in this embodiment, the diameters of the first positioning hole 72 and the second positioning hole 431 are equal. This arrangement helps to observe the alignment of the first positioning hole 72 and the second positioning hole 431, thereby determining the mating condition of the second arc plate 93 and the second arc groove 42 based on the alignment. When the mating is poor, the second detection unit 4 cannot abut against the gear meshing part 3, and the first positioning hole 72 and the second positioning hole 431 cannot be aligned, making it easy to determine that the curvature of the currently inspected gear rack 9 is substandard.

[0052] As one of the preferred embodiments, such as Figure 4 As shown, the detection device also includes a detachable pin 8, which is used to detect whether the first positioning hole 72 and the second positioning hole 431 are aligned. The pin 8 is used to cooperate with the first positioning hole 72 and the second positioning hole 431, and its outer diameter is slightly smaller than the diameter of the first positioning hole 72 and the second positioning hole 431. When the first positioning hole 72 and the second positioning hole 431 are aligned, the pin 8 can pass through the second positioning hole 431 and be inserted into the first positioning hole 72. This indicates that the curvature of the gear rack 9 under inspection meets the standard. When the first positioning hole 72 and the second positioning hole 431 are not aligned, the pin 8, after being inserted into the second positioning hole 431, interferes with the first detection platform 71 and cannot be inserted into the first positioning hole 72. This indicates that the curvature of the gear rack 9 under inspection does not meet the standard. This setting can quickly determine whether the curvature of the gear rack 9 under inspection meets the standard by the insertion of the pin 8, which is simple and fast, and greatly improves the detection speed and accuracy.

[0053] As an optional embodiment, the first detection unit 2 is integrally disposed with the first detection platform 71. This arrangement can effectively reduce the number of components in the detection device and simplify the production process of the detection device.

[0054] As an embodiment of the present invention, such as Figures 1-4 , Figure 6 As shown, a moving device 5 is provided on the detection base plate 1. The moving device 5 is connected to the second detection unit 4 and is used to move the second detection unit 4 closer to or away from the gear meshing part 3. The moving device 5 is used to drive the second detection unit 4 to move. When it drives the second detection unit 4 away from the gear meshing part 3, it provides sufficient space for the operator to mate the gear rack 9 to be inspected with the first detection unit 2 and the gear meshing part 3. After the gear rack 9 is mateted, the moving device 5 drives the second detection unit 4 to move towards the gear meshing part 3 to complete the inspection.

[0055] In this embodiment, as Figure 3 As shown, the moving device 5 includes a guide rail 51 and a slider 52. The guide rail 51 and the slider 52 are slidably connected, and the slider 52 is fixedly connected to the second detection unit 4. When the slider 52 moves along the guide rail 51, the slider 52 simultaneously drives the second detection unit 4 to move closer to or away from the gear meshing part 3.

[0056] In some optional embodiments, there is one or more guide rails 51, and the sliders 52 are arranged in a one-to-one correspondence with the guide rails 51. One or more guide rails 51 can smoothly drive the second detection unit 4 to move, thereby completing the arc detection of the gear rack 9.

[0057] In a preferred embodiment, there are two guide rails 51, each with a slider 52. Generally, with only one guide rail 51, the second detection unit 4 is prone to deviation during movement due to the clearance between the slider 52 and the guide rail 51, which can affect the detection accuracy of the detection device to some extent. The two guide rails 51 effectively curb the deviation of the second detection unit 4, thus ensuring the detection accuracy of the device. Of course, three or more guide rails 51 can improve the detection accuracy to some extent, but this will make the structure of the detection device more complex and will also affect the smoothness of the sliding of the second detection unit 4.

[0058] As an optional embodiment, a limiting structure 6 is provided at one end of the guide rail 51 away from the gear meshing portion 3. The limiting structure 6 is used to limit the travel of the slider 52. When the limiting structure 6 can prevent the slider 52 from disengaging from the guide rail 51, thereby limiting the travel of the second detection portion 4, when the slider 52 abuts against the limiting structure 6, the second detection portion 4 is away from the gear meshing portion 3, and there is sufficient space between them to accommodate the gear rack 9 to be detected.

[0059] As an optional embodiment, the second detection unit 4 includes a second detection body 41, on which a plurality of hollow through holes 44 are provided. The hollow through holes 44 can reduce the material consumption of the second detection unit 4 and reduce its weight, while also reducing the force it exerts on the warped gear rack 9, thus preventing it from forcibly correcting the warped deformation of the gear rack 9 during its movement toward the gear meshing part 3, which would affect the accuracy of the detection results.

[0060] Example 2

[0061] This embodiment discloses a method for detecting the curvature of an air conditioning gear rack, which includes the air conditioning gear rack curvature detection device described in Embodiment 1.

[0062] The detection method includes:

[0063] Step S1: Move the second detection unit 4 away from the gear meshing part 3;

[0064] Step S2: Connect the first arc-shaped plate 92 on the gear rack 9 under test to the first arc-shaped groove 22;

[0065] Step S3: Engage the first tooth 91 on the gear rack 9 under test with the second tooth 32;

[0066] Step S4: Move the second detection unit 4 close to the moving gear meshing part 3;

[0067] Step S5: Connect the second arc-shaped plate 93 on the gear rack 9 under test to the second arc-shaped groove 42;

[0068] Step S6: Determine whether the curvature of the gear rack 9 under test meets the standard based on the fit and insertion of the second arc plate 93 and the second arc groove 42.

[0069] It should be understood that when the curvature of the tested gear rack 9 meets the standard, such as Figure 5 As shown, the first arc plate 92 and the first arc groove 22, the second arc plate 93 and the second arc groove 42 are fully engaged and inserted, the first gear tooth 91 and the second gear tooth 32 are fully meshed, and the first detection unit 2 and the second detection unit 4 clamp the gear rack 9 to be inspected on the gear meshing part 3. When the curvature of the rack 9 under test is not up to standard, the rack 9 will warp and deform when the first arc plate 92 is engaged with the first arc groove 22. This will affect the meshing of the first gear tooth 91 and the second gear tooth 32, as well as the insertion and engagement of the second arc plate 93 and the second arc groove 42. When the curvature deviation is large, the second arc plate 93 will abut against the second detection body 41 of the second detection part 4 and will not be able to insert and engage with the second arc groove 42 at all. When the curvature deviation is small, the second arc plate 93 will barely insert into the second arc groove 42, but will not be able to abut against the bottom of the second arc groove 42. This will cause the second detection part 4 to be unable to abut against the gear meshing part 3, and it can also be determined that the curvature of the rack 9 under test is not up to standard. It should be noted that "judging whether the arc of the gear rack 9 under test meets the standard based on the fit and insertion of the second arc plate 93 and the second arc groove 42" can also be: judging whether the arc of the gear rack 9 under test meets the standard based on whether the second detection part 4 and the gear meshing part 3 abut. When the two abut, it is determined to meet the standard; when they cannot abut, it is determined to fail to meet the standard.

[0070] As one optional embodiment, a first detection platform 71 is provided on the left and right sides of the gear meshing part 3, and a first positioning hole 72 is provided on the first detection platform 71. A second detection platform 43 is provided at the left and right ends of the second detection part 4, and a second positioning hole 431 is provided on the second detection platform 43. The second positioning hole 431 is a through hole. The detection device also includes a pin 8. Step S6 includes:

[0071] Step S61: Insert the pin 8 into the second positioning hole 431, and determine whether the arc of the gear rack 9 under test meets the standard based on the insertion of the pin 8;

[0072] Step S62: When the pin 8 can pass through the second positioning hole 431 and be inserted into the first positioning hole 72, it is determined that the curvature of the currently inspected gear rack 9 meets the standard; when the pin 8 cannot enter the first positioning hole 72, it is determined that the curvature of the currently inspected gear rack 9 does not meet the standard.

[0073] The alignment of the second arc plate 93 and the second arc groove 42 is determined. When the alignment is poor, the second detection part 4 cannot abut against the gear meshing part 3, and the first positioning hole 72 and the second positioning hole 431 cannot be aligned. It can be easily determined that the curvature of the gear rack 9 under inspection is not up to standard. When the pin 8 can pass through the second positioning hole 431 and enter the first positioning hole 72, it means that the second detection part 4 abuts against the gear meshing part 3, and the curvature of the gear rack 9 under inspection is up to standard. The whole inspection process is simple and convenient, and can accurately determine whether the curvature of the gear rack 9 under inspection is up to standard.
