Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0029] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0030] like Figures 1 to 6 As shown, the present invention detects the real-time torque borne by the rotating shaft during the opening and closing of the convertible frame using a torque detection device. If the detected torque value is greater than the preset warning torque value, a fault signal is output to replace manual inspection. This invention provides a car convertible frame inspection device and a control method applied to this car convertible frame inspection device, which reduces the labor intensity of workers, improves inspection efficiency and accuracy, and reduces the impact of the environment on inspection.

[0031] like Figure 1 As shown in the figure, the automobile convertible frame testing device described in this embodiment includes: a base frame 1, a drive device 4, and a torque testing component 5.

[0032] The base frame 1 is provided with a rotating shaft 2, which rotates around the axis of the rotating shaft 2, and is used to connect with the to-be-tested convertible frame 3 and drive the to-be-tested convertible frame 3 to rotate in a first direction and open, or rotate in a second direction and close. The first direction and the second direction are opposite. The driving device 4 is connected with the rotating shaft 2. The torsion detection member 5 is arranged on the rotating shaft 2 and is used to detect the torsion value in the process that the rotating shaft 2 drives the to-be-tested convertible frame 3 to rotate. The controller is connected with and controls the driving device 4 and the torsion detection member 5, is used to acquire the torsion value, and outputs a fault signal when it is determined that the torsion value is greater than a warning torsion value.

[0033] By the above scheme, the real-time torsion borne by the rotating shaft 2 in the process that the convertible frame 3 is opened and closed is detected by the torsion detection member 5, and a fault signal is output if the detected torsion value is greater than a preset warning torsion value. The device is used to replace manual torsion detection, effectively reduces the labor intensity of workers, improves the detection efficiency and detection accuracy, and can also detect the torsion in a high-temperature or low-temperature environment, thereby reducing the influence of the extreme environment on the torsion detection accuracy.

[0034] In a specific embodiment of the present embodiment, the first direction is counterclockwise, and the second direction is clockwise. That is, the rotating shaft 2 drives the convertible frame 3 to rotate in the counterclockwise direction to control the convertible frame 3 to be opened to form a convertible of a vehicle, and the rotating shaft 2 drives the convertible frame 3 to rotate in the clockwise direction to control the opened convertible frame 3 to be closed.

[0035] In another specific embodiment of the present embodiment, the first direction is clockwise, and the second direction is counterclockwise. That is, the rotating shaft 2 drives the convertible frame 3 to rotate in the clockwise direction to control the convertible frame 3 to be opened to form a convertible of a vehicle, and the rotating shaft 2 drives the convertible frame 3 to rotate in the counterclockwise direction to control the opened convertible frame 3 to be closed.

[0036] In a specific embodiment of the present embodiment, the convertible frame detection device further comprises a power supply device 41. The power supply device 41 is arranged on the base frame 1 and is used to supply electric energy to the driving device 4.

[0037] By the above scheme, the power supply device 41 not only supplies electric energy to the driving device 4, but also balances the center of gravity of the detection device, reduces the center of gravity, and ensures the stability of the detection device.

[0038] Of course, the convertible frame detection device can also not be provided with the power supply device, but a counterweight is arranged at the position to balance the center distribution of the detection device. The power supply of the driving device 4 can be realized by an external power supply line.

[0039] In one specific implementation of the embodiment, the open rack detection device further comprises a position detection unit. The position detection unit detects the open position of the open rack, and when the front end and / or the rear end of the open rack reaches a certain predetermined detection position point, it indicates that the open rack is fully opened or fully closed. Specifically, a plurality of open rack finished products are extracted from a batch of open racks, and the extracted open rack 3 is controlled to open and close for a period of time t or a certain number of times n. If the detected open rack does not fail within the time t or the number of times n, it can be indicated that the open rack has high durability, and the batch of open racks is of qualified quality.

[0040] Further, referring to the accompanying drawings Figure 1 The base frame 1 comprises a base 10, a first column 11 and a second column 12.

[0041] The first column 11 and the second column 12 are arranged in parallel and spaced apart on one side of the base 10. The rotating shaft 2 is arranged between the first column 11 and the second column 12 and rotates relative to the first column 11 and the second column 12.

[0042] Specifically, referring to the accompanying drawings Figure 5 The base 10 comprises a first base plate 101 and a second base plate 102 connected perpendicularly and crosswise. The second base plate 102 divides the first base plate 101 into equal left and right parts, or the first base plate 101 divides the second base plate 102 into two parts that are not connected. The first column 11 and the second column 12 are arranged on the same side of the left and right ends of the first base plate 101, respectively. The power supply device 41 is arranged on one end of the second base plate.

[0043] With the above scheme, by optimizing the specific structure of the base frame 1, a larger contact area with the ground is ensured, the center of gravity of the overall detection device is lower, and the overall stability is improved.

[0044] More specifically, the power supply device 41 is arranged on one end of the second base plate 102 away from the opening direction of the open rack 3.

[0045] With the above scheme, the power supply device 41 is pressed against the ground, and when the open rack 3 is opened under the drive of the rotating shaft 2, the overall device will not be overturned due to the change of the center of gravity.

[0046] It can be understood that, in order to further improve the stability of the automobile open rack detection device, the distance from one end of the second base plate 102 close to the opening direction of the open rack 3 to the end provided with the power supply device 41 can be longer, or part of the second base plate 102 can be arranged in a structure in which the width gradually changes, i.e., the width of the end of the second base plate 102 close to the opening direction of the open rack 3 gradually increases as the distance from the first base plate 101 increases.

[0047] In a specific embodiment of the present embodiment, the first base plate 101 and the second base plate 102 are connected into one body through a mortise and tenon structure, and the bottom surfaces of the first base plate 101 and the second base plate 102 are flush after connection.

[0048] Further, the base 10 is provided with first adjusting holes (not shown in the figure) arranged along a first adjusting direction, and at least one of the first column 11 and the second column 12 moves along the first adjusting holes to adjust the distance between the first column 11 and the second column 12.

[0049] Further, the base frame 1 further comprises a third column 13. The third column 13 is arranged on one side of the base 10 and between the first column 11 and the second column 12; wherein the driving device 4 is arranged on the third column 13.

[0050] When the straight line length of the open-top frame 2 to be detected along the first base plate 101 is large or small, the above scheme can be used to adjust within a certain range according to the size of the open-top frame 2 to be detected, thereby enhancing the application range of the detection device.

[0051] Specifically, the first adjusting direction is the direction of increasing the distance between the first column 11 and the second column 12, that is, increasing the distance between the first column 11 and the third column 13, and / or increasing the distance between the second column 12 and the third column 13. Referring to the accompanying drawings, Figure 4 For the first column 11, the first adjusting direction is the direction away from the third column 13, and for the second column 12, the first adjusting direction is the direction away from the third column 13. It can be understood that the first adjusting direction is opposite for the first column 11 and the second column 12.

[0052] More specifically, in order to adjust the detection device to detect open-top frames 3 of different sizes, the position of the first column 11 can be adjusted alone, the position of the second column 12 can be adjusted alone, or the positions of the first column 11 and the second column 12 can be adjusted simultaneously.

[0053] Further, the third column 13 is provided with second adjusting holes along a second adjusting direction, and the driving device 4 moves along the second adjusting holes to adjust the distance between the driving device 4 and the base 10. The first adjusting direction and the second adjusting direction have an included angle.

[0054] Preferably, the first adjusting direction and the second adjusting direction are perpendicular, that is, the included angle is 90°.

[0055] Specifically, the second adjusting direction is a direction close to or away from the first base plate 101.

[0056] When the straight line length of the convertible frame 2 to be detected along the first column 11 (or the second column 12) is large or small, the above-mentioned scheme can be used to adjust within a certain range according to the size of the convertible frame 2 to be detected, thereby enhancing the application range of the detection device.

[0057] In a specific embodiment of the present embodiment, the third column 13 can also be adjusted in position to ensure that the third column 13 is arranged between the first column 11 and the second column 12.

[0058] The driving device 4 is a double-head motor. Using the above-mentioned scheme, only one motor can be used to provide the same driving force to both ends of the convertible frame 3, which is low in cost and ensures that the convertible frame 3 is opened synchronously at both ends.

[0059] In another specific embodiment of the present embodiment, the third column 13 can also be adjusted in position, but it is not necessary to ensure that the third column 13 is arranged between the first column 11 and the second column 12.

[0060] The driving device 4 includes two motors that provide driving force to both ends of the convertible frame 3, respectively. Using the above-mentioned scheme, more sufficient driving force can be provided to the convertible frame 3, which has a positive effect on improving the detection efficiency and detection accuracy to a certain extent.

[0061] In a specific embodiment of the present embodiment, the angle between the second adjusting direction and the first adjusting direction is greater than 90°, for example, 95° (not shown in the figure). That is, the third column 13 is not a vertical structural member, but as the distance from the first base plate 101 in the vertical direction increases, the distance from the first base plate 101 in the centroid of the horizontal cross section also increases.

[0062] The convertible frame 3 connected with the detection device has a front inclination angle, which is the reason why the third column 13 cannot be arranged on the first base plate 101 in the structural diagram. The front inclination angles of convertible frames of different specifications / different models are not completely consistent. Therefore, by using the above-mentioned scheme, the applicability of the convertible frame 3 of different specifications / different models can be adjusted, thereby expanding the universality of the convertible frame detection device.

[0063] It can be understood that the foregoing description is a description of the position setting in the structural diagram, and does not mean that the third column 13 can only be arranged on the second base plate 102. In fact, the third column 13 can also be arranged on the first base plate 101.

[0064] In one specific embodiment of the present application, the third column 13 is connected to the first base plate 101 and is arranged between the first column 11 and the second column 12, and the driving device 4 is arranged on the side of the third column 13 away from the power supply device 41.

[0065] In another specific embodiment of the present application, the open-top frame detection device comprises a mounting plate 14 arranged on the first column 11 and the second column 12. By adjusting and replacing the size and structure of the mounting plate 14, the forward inclination angle between the open-top frame 3 and the detection device can be controlled within a certain range, so that the axis of the rotating shaft 2 is within the side range of the first column 11 and the second column 12 as viewed from the side of the detection device.

[0066] In another specific embodiment of the present application, the mounting plate 14 is a component of the open-top frame 3. The mounting plate 14 is arranged on the base of the open-top frame 3, and the open-top frame 3 is mounted to the first column 11 and the second column 12 through the mounting plate 14. The first column 11 (the second column 12) is provided with an internal thread on the side of the side close to each other, and the mounting plate 14 is detachably connected to the first column 11 (the second column 12) through a bolt (screw).

[0067] In another specific embodiment of the present application, the base frame, the first column, the second column and the third column are all industrial aluminum profiles. The aluminum profiles have grooves and convex tracks, and the distance between the first column and the second column / the distance between the third column and the second column (the first column) / the position of the driving device on the third column are adjusted by the cooperation and sliding of the grooves and the convex tracks. Correspondingly, the driving assembly is provided with a matching groove or protrusion on the side facing the third column. Specifically, it further comprises a positioning assembly, which fixes the first column / second column / third column after adjusting the position to prevent sliding. In one preferred scheme, the aforementioned fixing member plays the role of the positioning assembly.

[0068] Further, referring to the accompanying drawings, Figure 2 The automobile open-top frame detection device further comprises a fixing member 6, which comprises an angle-shaped and connected first connecting plate 61 and a second connecting plate 62.

[0069] The fixing member 6 is disposed at the connection between the first column 11 and the base 10, with the first connecting plate 61 connecting the first column 11 and the second connecting plate connecting the base 10. The fixing member 6 is disposed at the connection between the second column 12 and the base 10, with the first connecting plate 61 connecting the second column 12 and the second connecting plate 62 connecting the base 10. The fixing member 6 is disposed at the connection between the third column 13 and the base 10, with the first connecting plate 61 connecting the third column 13 and the second connecting plate 62 connecting the base 10.

[0070] By adopting the above solution and setting the fastener 6, the reliability of the connection between the first column 11, the second column 12 and the third column 13 and the base 10 is improved.

[0071] Specifically, the first column 11, the second column 12 and the third column 13 are all connected to the base 10 by at least one fastener 6.

[0072] In one specific embodiment of this example, both the first column 11 and the second column 12 are connected to the base 10 via two fasteners 6. One of the two fasteners 6 is located on the side of the first column 11 (second column 12) near the third column 13, and the other is located on the side away from the third column 13.

[0073] Specifically, the first connecting plate 61 is fixedly connected to the first column 11, the second column 12, and the third column 13, and can be either a non-detachable or detachable connection. To ensure the reliability of the connection, a non-detachable connection method is preferred, such as riveting, bonding, or welding. The second connecting plate 62 is connected to the base 10. To achieve distance adjustment and control, a detachable connection method is preferred, such as threaded or pin-connected.

[0074] In one specific implementation of this embodiment, see Appendix Figure 1 , 2 In addition to the drive device 4, the drive device 4 is also connected to the third column 13 via the fixing member 6. To ensure the reliability of the installation of the drive device 4 and the transmission of driving force, it is preferable that the connection is made by at least two fixing members 6. Accordingly, the connection between the first connecting plate 61 and the drive device 4 can be a detachable connection or a non-detachable connection, and the connection between the second connecting plate 62 and the third column 13 is a detachable connection.

[0075] Furthermore, the rotating shaft 2 includes: a first shaft 21 and a second shaft 22.

[0076] The first shaft 21 is connected with the driving device 4. The second shaft 22 is coaxial with the first shaft 21 and is connected in a sliding manner, and the second shaft 22 is used to move away from the first shaft 21 or move close to the first shaft 21 along the axial direction of the second shaft 22. The torsion detection member 5 is connected with the second shaft 22.

[0077] In a specific embodiment of the present embodiment, the rotating shaft 2 further comprises a third shaft 23, and the torsion detection member 5 is connected between the second shaft 22 and the third shaft 23. The first shaft 21, the second shaft 22 and the third shaft 23 are coaxially arranged.

[0078] Specifically, the torsion detection member 5 is connected on the second shaft 22 and the third shaft 23 through flange bolts, and in order to ensure the coaxiality of the second shaft 22, the torsion detection member 5 and the third shaft 23, one or more layers of buffer pads are arranged in the adjacent flanges. Alternatively, the second shaft 22 and the torsion detection member 5 and the torsion detection member 5 and the third shaft 23 are connected through a shaft coupling. The shaft coupling can be an elastic pin coupling or a rigid coupling. In order to reduce the shaft center deviation, the elastic pin coupling is preferred.

[0079] Referring to FIG. 1, Figure 4 The rotating shaft 2 further comprises a fourth shaft 24, a fifth shaft 25 and a sixth shaft 26. The fourth shaft 24 is symmetrically arranged with the first shaft 21 relative to the driving device 4, the fifth shaft 25 is symmetrically arranged with the second shaft 22 relative to the driving device 4, and the sixth shaft 26 is symmetrically arranged with the third shaft 23 relative to the driving device 4. The torsion detection member 5 comprises a first torsion sensor 51 arranged between the second shaft 22 and the third shaft 23, and a second torsion sensor 52 arranged between the fifth shaft 25 and the sixth shaft 26. The first torsion sensor 51 and the second torsion sensor 52 are symmetrically arranged on the rotating shaft 2.

[0080] The first torsion sensor 51 and the second torsion sensor 52 can be static torsion sensors or dynamic torsion sensors. The type of sensor used can be changed according to the actual test conditions.

[0081] In a specific embodiment of the present embodiment, the first shaft 21 is arranged outside the second shaft 22, that is, the first shaft 21 has a hollow structure, and the second shaft 22 is inserted into the hollow structure in whole or in part. The second shaft 22 is provided with an elongated adjusting through hole 221 which penetrates the second shaft 22 radially and extends along the axial direction. The length direction of the adjusting through hole 221 is the axial direction of the second shaft 22, and the second shaft 22 moves along the length direction of the adjusting through hole 221 to adjust the corresponding position of the second shaft 22 and the first shaft 21, so as to change the axial length of the rotating shaft 2.

[0082] By the above scheme, the rotating shaft 2 has the size adjustment capability, and is applied to different specifications and sizes of the convertible frame 3, thereby improving the versatility of the detection device.

[0083] In another specific embodiment of the present embodiment, the second shaft sleeve is arranged outside the first shaft. The first shaft is provided with an elongated adjustment through hole, the length direction of the adjustment through hole is the axial direction of the first shaft, and the second shaft moves along the length direction of the adjustment through hole, so as to adjust the corresponding positions of the second shaft and the first shaft, so as to change the axial length of the rotating shaft.

[0084] Correspondingly, referring to FIG. 1, Figure 2 The fourth shaft 24 and the fifth shaft 25 also have a nested structure, that is, the fourth shaft 24 is sleeved outside the fifth shaft 25, or the fifth shaft 25 is sleeved outside the fourth shaft 24.

[0085] Further, the automobile convertible frame detection device further comprises a limiting pin 211, the limiting pin 211 passes through the adjustment through hole 221 to fix the first shaft 21 and the second shaft 22.

[0086] By the above scheme, the driving force of the first shaft (the fourth shaft) is transmitted to the second shaft (the fifth shaft), so that the radial sliding phenomenon does not occur, and the reliability of the transmission is ensured.

[0087] Specifically, referring to FIG. 1, Figure 3 The first shaft 21 is provided with a limiting hole 212 penetrating along the radial direction of the first shaft 21, the limiting pin 211 is inserted from one end of the limiting hole 212, penetrates the adjustment through hole 221, and then extends from the other end of the limiting hole 212.

[0088] When the first shaft 21 (the fourth shaft 24) rotates, the driving force is transmitted to the second shaft 22 (the fifth shaft 25) through the limiting pin 211.

[0089] In another specific embodiment of the present embodiment, in order to further ensure the reliability of the transmission, the limiting pin also has an axial extension length in common with the adjustment through hole 221, and the size of the limiting hole 212 matches the size of the limiting pin.

[0090] In another specific embodiment of the present embodiment, in order to further ensure the reliability of the transmission, the limiting pin is provided with a plurality of limiting pins, which jointly participate in the transmission of the driving force. Further, the cross-sectional diameters of the upper end and the lower end of the limiting pin are different (in the shape of a truncated cone), the hole diameters of the upper end and the lower end of the corresponding limiting hole are also different, and the plurality of limiting pins are arranged in an inverted manner along the axial direction. Alternatively, the cross-sectional diameters of the upper end and the lower end of the limiting pin are different (in the shape of a truncated cone), the hole diameters of the upper end and the lower end of the corresponding limiting hole are also different, and the plurality of limiting pins are arranged in an inverted manner along the axial direction and the radial direction (corresponding to the adjusting through hole provided with a plurality of groups of intersections).

[0091] The specific application of the open-top frame detection device provided by the present embodiment is that the automobile open-top frame detection device provided by the present application can replace manual detection to detect the yield rate, and can also detect the durability of the open-top frame. In actual manual detection operation, workers can only detect the torque within a small temperature range (for example, 0-30 DEG C), and cannot operate in a higher or lower temperature environment. In order to accurately obtain the durability of the open-top frame product, it is necessary to control the open-top frame to be opened and closed for a certain time t and / or a certain number n in different temperature environments. Therefore, the detection device has a wider temperature application range (for example, -20-60 DEG C) compared with manual operation, and therefore more accurate durability data can be obtained.

[0092] Due to long-term use or unreliable factory quality, mechanical structures are subject to wear and tear and fatigue failure. When the open-top frame cannot be normally fully opened or fully closed, the driving torque of the driving device 4 applied to the open-top frame cannot be effectively transmitted to the driving assembly of the open-top frame. At this time, the driving assembly (linkage structure for controlling the opening of the open-top frame) of the open-top frame is jammed or the transmission force is interfered, the resistance of the torque detection piece 5 increases, and the torque value detected by the torque detection piece 5 is suddenly changed or abnormally increased. At this time, it indicates that the open-top frame is abnormal.

[0093] The present embodiment also provides a control method of an automobile open-top frame detection device, which is applied to the automobile open-top frame detection device described above, and the method comprises the following steps of:

[0094] receiving the torque value sent by the torque detection piece; the torque value is a value detected by the torque detection piece 5 in the process of rotating the open-top frame 3 to be detected under the driving of the rotating shaft 2;

[0095] If the torque value is greater than the preset warning torque value, a fault signal is output.

[0096] By using the above scheme, the yield performance of the open-top frame is automatically detected; when the detected open-top frame has a problem, a fault signal is output to timely remind the technical personnel to intervene and adjust, thereby ensuring the intelligence of the detection device.

[0097] Specifically, if the actual torque value is greater than the preset warning torque value, the controller outputs a fault signal and controls the driving device 4 to pause operation and stop driving the rotating shaft 2.

[0098] In a specific embodiment of the present embodiment, the output fault signal can be in the form of a warning on the information display panel of the detection device through sound and / or text and / or color, or in the form of sending a fault phenomenon to a data processing center through the Internet of Things and then to a smart terminal of a technician. The smart terminal refers to an electronic device capable of receiving data information, such as a smart bracelet, a mobile phone, a tablet computer, a computer, and the like.

[0099] Specifically, the preset warning torque value is self-provided by the detection device or manually input by the technician before the detection device is operated.

[0100] The above description is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above with reference to the preferred embodiment, the present application is not limited thereto. Any person skilled in the art can make some changes or modifications to the above-mentioned technical content without departing from the scope of the technical solution of the present application, and any simple modification, equivalent change and modification of the above-mentioned technical content within the scope of the technical solution of the present application are still within the scope of the present application.
