Description

Technical Field

[0001] The utility model belongs to the technical field of hinge inspection tools, and in particular relates to a hinge inspection tool. Background Art

[0002] The scissor door has only one hinge in its structure, and has a large opening angle. The hinge includes a body leaf, a door leaf and a limit ball. The limit ball is set on the door leaf, and the cantilever of the door leaf is long. Due to the influence of the lever effect, the accuracy of the hinge itself, especially the coplanarity of the four mounting surfaces of the body leaf, will amplify the error of the motion envelope of the scissor door and the surface difference of the appearance gap in the door area by dozens of times. The manufacturing accuracy of the scissor door hinge is a manufacturing difficulty of the scissor door system, which directly affects the door movement, sealing, wind noise and the coordination effect of the whole vehicle.

[0003] At present, the existing hinge inspection fixtures cannot provide accurate positioning and clamping functions for hinges, resulting in the inability to accurately detect hinges. For example, the hinge inspection fixture only uses the body leaf as a reference, and cannot perform coplanarity detection on the mounting surface of the body leaf in the positioning and fixing state. The coplanarity of the mounting surface of the body leaf will greatly affect the front and rear door surface difference; or the limit ball detection is only performed based on the door leaf, and the body leaf cannot be used as a reference for detection, resulting in poor detection accuracy.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] The utility model embodiment provides a hinge inspection tool, referring to Figure 1-4The hinge inspection fixture includes a first support seat 1, a second support seat 2 and a clamping mechanism 3; the first support seat 1 is arranged along the first direction, and a first positioning pin 4 is provided on the first support seat 1; the second support seat 2 includes a support plate 21 arranged along the second direction, and a second positioning pin 5 is provided on the support plate 21, and the second positioning pin 5 cooperates with the first positioning pin 4 to position the hinge; the clamping mechanism 3 is arranged on the support plate 21 for clamping the hinge.

[0041] The first direction and the second direction intersect, and may be vertical or nearly vertical. The axial directions of the first positioning pin 4 and the second positioning pin 5 intersect, and may be vertical or nearly vertical.

[0042] As an example, the hinge inspection fixture includes a first support seat 1, a second support seat 2 and a clamping mechanism 3; the first support seat 1 is arranged along the first direction, and a first positioning pin 4 is provided on the first support seat 1, and the axial direction of the first positioning pin 4 is perpendicular or nearly perpendicular to the first support seat 1, which can provide the hinge with a positioning perpendicular to or nearly perpendicular to the first direction; the second support seat 2 includes a support plate 21 arranged along the second direction, and a second positioning pin 5 is provided on the support plate 21, and the axial direction of the second positioning pin 5 is perpendicular or nearly perpendicular to the support plate 21, which can provide the hinge with a positioning perpendicular to or nearly perpendicular to the second direction; the second positioning pin 5 on the support plate 21 cooperates with the first positioning pin 4 on the first support seat 1, and can position the hinge perpendicular to or nearly perpendicular to the first direction and perpendicular to or nearly perpendicular to the second direction, thereby realizing precise positioning of the hinge. For example, the first direction is the X direction, the second direction is the Z direction, and the third direction is the Y direction. The first support seat 1 is arranged along the X direction, and the axial direction of the first positioning pin 4 is perpendicular to the first support seat 1. The first positioning pin 4 can provide Y / Z direction positioning for the hinge; the support plate 21 is arranged along the Z direction, and the axial direction of the second positioning pin 5 is perpendicular to the support plate 21. The second positioning pin 5 can provide X / Y direction positioning for the hinge. The clamping mechanism 3 is arranged on the support plate 21 to clamp the hinge, ensure that the hinge is fixed stably and firmly, provide convenience for subsequent scanning and detection of the hinge, and improve the detection accuracy.

[0043] In this example, the scissor door hinge is placed on the hinge inspection fixture. In order to ensure the overall positioning stability, after the door leaf is positioned, it needs to be close to the mounting surface of the body leaf to locate the rotation direction. The second positioning pin 5 on the support plate 21 of the door leaf of the fixed hinge is used as a fixed reference, and the first positioning pins 4 on the first support seat 1 of the body leaf of the fixed hinge can be used as a floating reference. Taking the four first positioning pins 4 as an example, two detection states can be achieved: one is that the four references are simultaneously attached and regarded as completely positioned, which is used to detect most hinge accuracy; the other is that two references are attached, and the other two references are separated and regarded as positioning, which is used to detect the coplanarity of the four mounting surfaces of the body leaf. By switching the floating reference, the coplanarity detection of the mounting surface of the body leaf can be realized while detecting the hinge accuracy. Among them, the number of first positioning pins 4 is not limited and is designed according to actual needs.

[0044] This embodiment introduces the first set of detection benchmarks of the hinge inspection fixture, which is designed for the scissor door hinge in the closed state. The scissor door hinge includes a door leaf and a body leaf. The door leaf positioning hole and the body leaf positioning hole of the hinge are respectively installed on the first positioning pin 4 and the second positioning pin 5 of the hinge inspection fixture, so that the hinge can be positioned in the first direction and the second direction to achieve accurate positioning of the hinge; the hinge is clamped by the clamping mechanism 3 to ensure that the hinge is fixed stably and firmly, which provides convenience for subsequent scanning and detection of the hinge and improves the detection accuracy.

[0045] In one embodiment, referring to Figure 1 , Figure 5 and Figure 6 The hinge inspection fixture also includes a sliding assembly 6, which includes a slide rail and a slider; the slide rail is arranged on one side of the first support seat 1 along the first direction, and the slider is movably installed in the slide rail and connected to the support plate 21 to adjust the distance between the support plate 21 and the first support seat 1.

[0046] As an example, the hinge gauge also includes a sliding assembly 6, which includes a sliding rail and a slider; the sliding rail is arranged on one side of the first support seat 1 along a first direction, one end of the slider is connected to the support plate 21, and the slider is movably installed in the sliding rail to adjust the distance between the support plate 21 and the first support seat 1. When in use, the scissor door hinge is first placed on the hinge gauge, and then the slider is moved in the sliding rail to insert the second positioning pin 5 on the hinge gauge into the hinge positioning hole, and finally the clamping mechanism 3 is flipped and clamped to achieve the positioning of the door leaf.

[0047] In one embodiment, referring to Figure 1 , Figure 2 and Figure 3 The clamping mechanism 3 includes at least two first clamping assemblies 31 , and the at least two first clamping assemblies 31 are arranged on the support plate 21 at intervals along the third direction.

[0048] The third direction, the second direction and the first direction intersect each other.

[0049] As an example, the clamping mechanism 3 includes at least two first clamping components 31, and at least two first clamping components 31 are arranged on the support plate 21 at intervals along the third direction, so as to clamp the hinge and ensure that the hinge is fixed stably and securely, thereby facilitating subsequent scanning and detection of the hinge and improving detection accuracy.

[0050] In one embodiment, referring to Figure 1 and Figure 5 The first clamping assembly 31 includes a positioning column 311 and a first reversible clamp 312; the positioning column 311 is arranged on the support plate 21 along the first direction, one end of the first reversible clamp 312 is rotatably mounted on the support plate 21, and the other end of the first reversible clamp 312 cooperates with the positioning column 311 to clamp the hinge on the positioning column 311.

[0051] As an example, the first clamping assembly 31 includes a positioning column 311 and a first reversible chuck 312; the positioning column 311 is arranged on the support plate 21 along the first direction, and is used to support and position the hinge; one end of the first reversible chuck 312 is rotatably mounted on the support plate 21, and the other end of the first reversible chuck 312 cooperates with the positioning column 311, and is used to clamp the hinge on the positioning column 311, ensuring that the hinge is fixed stably and firmly, providing convenience for subsequent scanning and detection of the hinge, and improving the detection accuracy. Among them, when the first reversible chuck 312 includes a first reversible chuck 312 that is flipped along the axis of the second direction and a first reversible chuck 312 that is flipped along the axis of the third direction, it can be fixed in multiple directions.

[0052] In one embodiment, referring to Figure 1 and Figure 5 The first flip-up clamp 312 includes a first connecting arm 3121, a second connecting arm 3122 extending from one end of the first connecting arm 3121 along the first direction, and a first clamping block 3123 arranged on the second connecting arm 3122; the other end of the first connecting arm 3121 is rotatably mounted on the support plate 21 around the second direction or the third direction, and the first clamping block 3123 cooperates with the positioning column 311.

[0053] As an example, the first flip-up chuck 312 can be designed in the following manner: the first flip-up chuck 312 includes a first connecting arm 3121, a second connecting arm 3122 and a first clamping block 3123; the first connecting arm 3121 is arranged along the second direction, the second connecting arm 3122 is extended from one end of the first connecting arm 3121 along the first direction, the first clamping block 3123 is arranged on one end of the second connecting arm 3122, and the other end of the first connecting arm 3121 is rotatably mounted on the support plate 21 around a third direction, so that the first connecting arm 3121 can be flipped along the second direction, and cooperate with the positioning column 311 through the first clamping block 3123, so that the hinge can be clamped on the positioning column 311, ensuring that the hinge is fixed stably and firmly, providing convenience for subsequent scanning and detection of the hinge, and improving detection accuracy.

[0054] As another example, the first flip-up chuck 312 can be designed in the following manner: the first flip-up chuck 312 includes a first connecting arm 3121, a second connecting arm 3122 and a first clamping block 3123; the first connecting arm 3121 is arranged along a third direction, the second connecting arm 3122 is extended from one end of the first connecting arm 3121 along the first direction, and the first clamping block 3123 is arranged on one end of the second connecting arm 3122; the other end of the first connecting arm 3121 is rotatably mounted on the support plate 21 around the second direction, so that the first connecting arm 3121 can be flipped along the third direction and cooperate with the positioning column 311 through the first clamping block 3123, so that the hinge can be clamped on the positioning column 311, ensuring that the hinge is fixed stably and firmly, providing convenience for subsequent scanning and detection of the hinge, and improving detection accuracy.

[0055] Among them, the first connecting arm 3121 can be set as the first connecting arm 3121 that flips along the second direction, and can also be set as the first connecting arm 3121 that flips along the third direction; the first connecting arm 3121 and the second connecting arm 3122 cooperate to form an L-shaped structure, and the first clamping block 3123 is set on one end of the second connecting arm 3122 and cooperates with the positioning column 311, so that the hinge can be clamped on the positioning column 311 from multiple directions.

[0056] In one embodiment, referring to Figure 2 , Figure 3 and Figure 4 The first positioning pin 4 includes a fixed positioning pin 41 and an adjustable positioning pin 42; the fixed positioning pin 41 and the adjustable positioning pin 42 are respectively arranged corresponding to different positions of the hinge; or, the fixed positioning pin 41 is in contact with the hinge, and the adjustable positioning pin 42 is in contact with the hinge or not.

[0057] As an example, the first locating pin 4 includes a fixed locating pin 41 and an adjustable locating pin 42, and the fixed locating pin 41 and the adjustable locating pin 42 are respectively arranged corresponding to different positions of the hinge; when the fixed locating pin 41 and the adjustable locating pin 42 are respectively in contact with different positions of the hinge, the scissor door hinge is placed on the hinge inspection fixture. In order to ensure the overall positioning stability, after the door leaf is positioned, it is necessary to adhere to the mounting surface of the vehicle body leaf to locate the rotation direction. When the fixed locating pin 41 and the adjustable locating pin 42 are in contact with the hinge at the same time, it is regarded as completely positioned. At this time, it is used to detect most of the hinge precision control elements.

[0058] Alternatively, the fixed locating pin 41 is in contact with the hinge, and the adjustable locating pin 42 is not in contact with the hinge. The scissor door hinge is placed on the hinge inspection fixture. In order to ensure the overall positioning stability, after the door leaf is positioned, it is necessary to adhere to the body leaf mounting surface to locate the rotation direction. The fixed locating pin 41 is in contact with the hinge, which is considered to be completely positioned. The adjustable locating pin 42 is separated from the hinge, which is used to detect the coplanarity of the body leaf mounting surface.

[0059] In this example, there is no limit on the number of first locating pins 4, which are designed according to actual needs. For example, when placing the scissor door hinge on the hinge inspection fixture, in order to ensure the overall positioning stability, after the door leaf is positioned, it needs to be close to the mounting surface of the body leaf to locate the rotation direction, and the second locating pin 5 on the support plate 21 of the door leaf of the fixed hinge is used as a fixed reference, and several first locating pins 4 on the first support seat 1 of the body leaf of the fixed hinge can be floating references. Taking four first locating pins 4 as an example, the first locating pins 4 include fixed locating pins 41 and adjustable locating pins 42, which are respectively in contact with different positions of the hinge. The four references are simultaneously in contact with each other, which is considered to be completely positioned. At this time, it is used to detect most of the hinge precision control elements.

[0060] For example, a scissor door hinge is placed on a hinge inspection fixture. In order to ensure the overall positioning stability, after the door leaf is positioned, it needs to be close to the mounting surface of the vehicle body leaf to locate the rotation direction. The second positioning pin 5 on the support plate 21 of the door leaf of the fixed hinge is used as a fixed reference. Several first positioning pins 4 on the first support seat 1 of the vehicle body leaf of the fixed hinge can be floating references. Taking four first positioning pins 4 as an example, the four first positioning pins 4 include two fixed positioning pins 41 and two adjustable positioning pins 42. The two fixed positioning pins 41 are arranged at intervals, and the two fixed positioning pins 41 are in contact with different positions of the hinge respectively; the two adjustable positioning pins 42 are arranged at intervals, and the two adjustable positioning pins 42 do not contact the hinge; two references are in contact, and the other two references are separated, which is considered to be completed, that is, the two fixed positioning pins 41 are in contact, and the other two adjustable positioning pins 42 are separated, which is considered to be completed. At this time, it is used to detect the coplanarity of the four mounting surfaces of the vehicle body leaf. By switching the floating reference, the coplanarity detection of the mounting surface of the vehicle body leaf can be realized while detecting the hinge accuracy.

[0061] In one embodiment, referring to Figure 5 and Figure 6 The second support seat 2 also includes a support column 22 arranged along the second direction, and the first end of the support column 22 is connected to the first support seat 1; the second end of the support column 22 cooperates with the first positioning pin 4 for positioning the hinge.

[0062] As an example, the second set of detection benchmarks of the hinge inspection fixture is introduced, which can be positioned when the hinge is opened to the maximum opening state, so as to realize the accuracy of the limit ball when the hinge is opened. Taking the body page as the benchmark can shorten the detection dimension chain, and ensure the travel position and automatic opening and closing sensing function of the hinge. The second support seat 2 also includes a support column 22 arranged along the second direction, and the first end of the support column 22 is connected to the first support seat 1. The first support seat 1 includes a first fixed plate 11 arranged along the first direction and a second fixed plate 12 extending from one side of the first fixed plate 11 along the first direction. The first fixed plate 11 and the second fixed plate 12 are L-shaped structures. The first end of the support column 22 is fixed to the end of the second fixed plate 12 away from the first fixed plate 11, and the distance between the support column 22 and the first fixed plate 11 is greater than the distance between the support plate 21 and the first fixed plate 11. The axial direction of the support column 22 is perpendicular or nearly perpendicular to the first support seat 1, and can provide the hinge with a positioning perpendicular or nearly perpendicular to the second direction. The axial direction of the first positioning pin 4 is perpendicular or nearly perpendicular to the first support seat 1, and can provide the hinge with positioning perpendicular or nearly perpendicular to the first direction; the first positioning pin 4 cooperates with the second end of the support column 22, and can position the hinge perpendicular or nearly perpendicular to the first direction and perpendicular or nearly perpendicular to the second direction, thereby achieving precise positioning of the hinge.

[0063] The hinge inspection fixture in this example has two sets of detection references. The first locating pin 4 on the first support seat 1 and the second locating pin 5 on the support plate 21 serve as the structure of the first set of detection references, which are designed for the scissor door hinge in the closed state and are used to position the hinge; the first locating pin 4 on the first support seat 1 and the support column 22 serve as the structure of the second set of detection references, which are designed for the hinge opened to the maximum opening state and are used to position the hinge.

[0064] In one embodiment, referring to Figure 5 and Figure 6 A portion of the first positioning pin 4 is provided with a retractable pin, and the second end of the support column 22 cooperates with the first positioning pin 4 with the retractable pin to position the hinge.

[0065] As an example, a portion of the first positioning pin 4 is provided with a retractable pin, and the axial direction of the first positioning pin 4 is perpendicular or nearly perpendicular to the first support seat 1, so as to provide the hinge with a positioning perpendicular or nearly perpendicular to the first direction; the first positioning pin 4 with a retractable pin cooperates with the second end of the support column 22, so as to position the hinge perpendicular or nearly perpendicular to the first direction and perpendicular or nearly perpendicular to the second direction, so as to realize precise positioning of the hinge.

[0066] The utility model embodiment provides a hinge inspection tool, referring to Figure 5 and Figure 6 The hinge inspection fixture includes a first support seat 1, a second support seat 2 and a clamping mechanism 3; the first support seat 1 is arranged along the first direction, and a first positioning pin 4 is provided on the first support seat 1; the second support seat 2 includes a support column 22 arranged along the second direction, and the first end of the support column 22 is connected to the first support seat 1; the second end of the support column 22 cooperates with the first positioning pin 4 for positioning the hinge; the clamping mechanism 3 is arranged on the first support seat 1 for clamping the hinge.

[0067] The first direction intersects with the second direction, and the axial directions of the first positioning pin 4 and the second positioning pin 5 intersect with each other (they may be vertical or nearly vertical).

[0068] As an example, the hinge inspection fixture includes a first support seat 1, a second support seat 2 and a clamping mechanism 3; the first support seat 1 is arranged along the first direction, and a first positioning pin 4 is arranged on the first support seat 1, and the axial direction of the first positioning pin 4 is perpendicular or nearly perpendicular to the first support seat 1, which can provide the hinge with a positioning perpendicular to or nearly perpendicular to the first direction; the second support seat 2 includes a support column 22 arranged along the second direction, and the first end of the support column 22 is connected to the first support seat 1, and the first support seat 1 includes a first fixing plate 11 arranged along the first direction and a second fixing plate 12 extending from one side of the first fixing plate 11 along the first direction, and the first fixing plate 11 and the second fixing plate 12 are L-shaped structures, and the first end of the support column 22 is fixed to an end of the second fixing plate 12 away from the first fixing plate 11, and the distance between the support column 22 and the first fixing plate 11 is greater than the distance between the support plate 21 and the first fixing plate 11. The axial direction of the support column 22 is perpendicular or nearly perpendicular to the first support seat 1, and the hinge can be provided with a positioning perpendicular to or nearly perpendicular to the second direction. The axial direction of the first positioning pin 4 is perpendicular or nearly perpendicular to the first support seat 1, and can provide the hinge with a positioning perpendicular or nearly perpendicular to the first direction; the first positioning pin 4 cooperates with the second end of the support column 22, and can position the hinge perpendicular or nearly perpendicular to the first direction and perpendicular or nearly perpendicular to the second direction, so as to achieve precise positioning of the hinge. The clamping mechanism 3 includes a second clamping assembly 32 arranged on the first support seat 1, which is used to clamp the hinge to ensure that the hinge is fixed stably and firmly, provide convenience for subsequent scanning and detection of the hinge, and improve the detection accuracy.

[0069] This example introduces the second set of detection benchmarks for the hinge gauge, which can be positioned when the hinge is opened to the maximum opening state, and the accuracy of the limit ball when the hinge is opened can be detected. Taking the body page as the benchmark can shorten the detection dimension chain and ensure the travel position and automatic opening and closing sensing function of the hinge. Among them, the support column 22 is a floating benchmark. When the hinge is opened to the maximum opening state, the positioning is considered to be completed. At this time, the accuracy of the limit ball when the hinge is opened can be detected.

[0070] In this embodiment, the scissor door hinge is applied to the scissor door. The hinge inspection fixture can solve the problem that the scissor door is affected by the lever effect. The accuracy of the scissor door hinge itself will amplify the error of the movement of the scissor door and the matching of the vehicle body by dozens of times, thereby causing quality problems of the door opening and closing, vehicle sealing, wind noise, and appearance; and it can detect the accuracy of the limit ball in the maximum opening state of the scissor door hinge to ensure the automatic opening and closing sensing function.
