[0044] See also Figures 1 to 7 As shown, an embodiment of the detection device for the hinge of the automobile engine hood provided by the utility model.

[0045] The automobile engine hood hinge 1 includes a first plate 11, a second plate 12, and a rotating shaft 13.

The second plate 12 has a second abutting surface 121 and a second connecting hole 122.

[0046] The above-mentioned detection device comprises:

[0047] Rack unit 2;

[0048] A positioning unit 3 is mounted on the frame unit 2 and is used to maintain the first plate 11 at a set position and posture;

[0049] The toggle unit 4 is installed on the frame unit 2, and the toggle unit 4 includes a toggle head mounting arm 41, a toggle head 42, a toggle head rotation driving device 43, a torque detecting member 44 and a toggle head lifting driving device 45. The toggle head 42 is connected to one end of the toggle head mounting arm 41, and the toggle head 42 is used to connect the second plate 12. The toggle head rotation driving device 43 is connected to the other end of the toggle head mounting arm 41. The toggle head rotation driving device 43 drives the toggle head 42 to rotate from the initial position to the first detection position and the second detection position. The torque detecting member 44 is connected between the toggle head rotation driving device 43 and the toggle head mounting arm 41. The torque detecting member 44 is used to detect the torque applied to the rotating shaft member 13. The toggle head lifting driving device 45 is connected to the toggle head rotation driving device 43. The toggle head lifting driving device 45 drives the toggle head rotation driving device 43 to rise and fall in the vertical direction.

[0050] A first detection unit 5 is mounted on the frame unit 2. The first detection unit 5 includes a first test head mounting plate 51, a first flatness detection member 52, and a first hole position detection member 53. The first flatness detection member 52 is connected to the first test head mounting plate 51 and is used to detect the flatness of the second abutting surface 121 of the second plate 12 of the first detection station. The first hole position detection member 53 is connected to the first test head mounting plate 51 and is used to detect the position of the second connecting hole 122 of the second plate 12 of the first detection station.

[0051] The second detection unit 6, the above-mentioned second detection unit 6 is installed on the above-mentioned frame unit 2, the above-mentioned second detection unit 6 includes a second test head mounting plate 61, a second flatness detection component 62 and a second hole position detection component 63, the above-mentioned second flatness detection component 62 is connected to the above-mentioned second test head mounting plate 61, the above-mentioned second flatness detection component 62 is used to detect the flatness of the second abutting surface 121 of the second plate 12 of the above-mentioned second detection station, the above-mentioned second hole position detection component 63 is connected to the above-mentioned second test head mounting plate 61, the above-mentioned second hole position detection component 63 is used to detect the position of the second connecting hole 122 of the second plate 12 of the above-mentioned second detection station.

[0052] The above-mentioned first plate 11 is used to be fixedly connected to the vehicle body. When the above-mentioned first plate 11 is fixedly connected to the vehicle body, the above-mentioned first abutting surface 111 abuts against the vehicle body, and the above-mentioned first connecting hole 112 is connected to the vehicle body connecting hole through a connecting member. The above-mentioned second plate 12 is used to be fixedly connected to the hatch cover. When the above-mentioned second plate 12 is fixedly connected to the hatch cover, the above-mentioned second abutting surface 121 abuts against the hatch cover, and the above-mentioned second connecting hole 122 is connected to the hatch cover connecting hole through a connecting member.

[0053] When testing the automobile engine hood hinge 1, the first plate 11 is fixed in position by the positioning unit 3. At this time, the axis of the rotating shaft 13 is colinear with the rotation axis of the toggle head mounting arm 41, and the toggle unit 4 drives the second plate 12 to rotate. At this time, the torque detected by the torque detection member 44 is related to the smoothness of the rotation of the second plate 12. When the torque detected by the torque detection member 44 is within the set range, it means that the automobile engine hood hinge 1 can rotate smoothly when in use. The first abutting surface 111, the first connecting hole 112 of the first plate 11 and the second abutting surface 121 and the second connecting hole 122 of the second plate 12 affect the matching relationship between the vehicle body and the hood. When the flatness of the second abutting surface 121 and the position of the second connecting hole 122 are within the set range, it means that the automobile engine hood hinge 1 can fit tightly with the vehicle body when in use.

[0054] In this embodiment, the positioning unit 3 includes:

[0055] A support base 31 , the support base 31 is used to support the first plate 11 , and the support base 31 abuts against the first abutting surface 111 of the first plate 11 ;

[0056] A positioning pin 32 is used to limit the translation of the first plate 11 , and the positioning pin 32 is inserted into the first connecting hole 112 ;

[0057] Press head mounting arm 33;

[0058] A pressing head 34 , the pressing head 34 being connected to one end of the pressing head mounting arm 33 , and the pressing head 34 being used to press the first plate 11 onto the supporting base 31 ;

[0059] The pressure head driving device 35 is connected to the other end of the pressure head mounting arm 33 , and is used to drive the pressure head 34 to press or loosen the first plate 11 .

[0060] The support surface of the support base 31 contacts the first abutting surface 111 of the first plate 11, so the plane of the first abutting surface 111 can be determined. The positioning pin 32 passes through the first connecting hole 112 of the first plate 11, so the position of the first connecting hole 112 can be determined. The positions of the first detection unit 5 and the second detection unit 6 during detection are in a preset relative relationship with the support base 31 and the positioning pin 32. Therefore, the flatness of the second abutting surface 121 and the position of the second connecting hole 122 detected by the first detection unit 5 and the second detection unit 6 are the relative positional relationships of the first abutting surface 111, the first connecting hole 112, the second abutting surface 121 and the second connecting hole 122. The position detection member 36 is used to detect whether the second plate 12 at the initial workstation is at the set position.

[0061] In this embodiment, the shift head 42 includes a plurality of shift rods extending vertically.

[0062] After the automobile engine hood hinge 1 is positioned, the second plate 12 is in an upright state, the lower end of the above-mentioned lever is a free end, and the upper end of the above-mentioned lever is connected to the lever head mounting arm 41. When the lever head lifting drive device 45 drives the lever downward, the second plate 12 is inserted between the levers. When the lever head rotation drive device 43 drives the lever to rotate, the lever pushes the second plate 12 to rotate.

[0063] In this embodiment, the first flatness detection member 52 and the second flatness detection member 62 are both displacement sensors.

[0064] The displacement sensor can measure the distance between different positions of the second abutting surface 121 of the second plate 12. If the distances between the displacement sensor and different positions of the second abutting surface 121 of the second plate 12 are all within the set range, the flatness of the second abutting surface 121 of the second plate 12 is within the set range. If the distances between the displacement sensor and different positions of the second abutting surface 121 of the second plate 12 exceed the set range, the flatness of the second abutting surface 121 of the second plate 12 is not within the set range.

[0065] In this embodiment, the first hole position detection member 53 and the second hole position detection member 63 are both standard blocks.

[0066] The standard block is a block of fixed shape and size. When the standard block can be inserted exactly into the second connecting hole 122 of the second plate 12, the position of the second connecting hole 122 of the second plate 12 is at the set position. When the standard block cannot be inserted exactly into the second connecting hole 122 of the second plate 12, the position of the second connecting hole 122 of the second plate 12 is not at the set position.

[0067] In this embodiment, the first inspection unit 5 further includes a first test head translation drive device 54, which is connected to the first test head mounting plate 51 and drives the first flatness detection member 52 and the first hole position detection member 53 to move toward and away from the second plate 12 of the first inspection station along the first inspection direction. The second inspection unit 6 further includes a second test head translation drive device 64, which is connected to the second test head mounting plate 61 and drives the second flatness detection member 62 and the second hole position detection member 63 to move toward and away from the second plate 12 of the second inspection station along the second inspection direction. The second inspection unit 6 further includes a third test head translation drive device 65, which is connected to the second test head translation drive device 64 and drives the second test head mounting plate 61 to move along a third inspection direction, wherein the third inspection direction is perpendicular to the second inspection direction.

[0068] Since the toggle unit 4 needs to drive the automobile engine hood hinge 1 to rotate at different positions, the first detection unit 5 and the second detection unit 6 need to avoid the rotation trajectory of the automobile engine hood hinge 1, resulting in the first detection unit 5 and the second detection unit 6 being farther away from the second plate 12, affecting the detection accuracy and even making it impossible to detect. Through the first test head translation drive device 54, the second test head translation drive device 64 and the third test head translation drive device 65, when the second plate 12 of the first detection station is detected, the first detection unit 5 is close to the first detection station, and at other times, the first detection unit 5 is away from the first detection station. When the second plate 12 of the second detection station is detected, the second detection unit 6 is close to the second detection station, and at other times, the second detection unit 6 is away from the second detection station.

[0069] In this embodiment, the detection device includes one of the above-mentioned shifting units 4, two of the above-mentioned positioning units 3, two of the above-mentioned first detection units 5 and two of the above-mentioned second detection units 6;

[0070] The two positioning units 3 are symmetrically arranged relative to the toggle unit 4;

[0071] The two first detection units 5 are symmetrically arranged relative to the dial unit 4;

[0072] The two second detection units 6 are arranged symmetrically relative to the dialing unit 4 .

[0073] Since automobile engine hood hinges 1 are generally used in pairs, each pair of automobile engine hood hinges 1 is symmetrical on the left and right. Therefore, through one of the above-mentioned toggle units 4, two of the above-mentioned positioning units 3, two of the above-mentioned first detection units 5 and two of the above-mentioned second detection units 6, the same detection device can detect a symmetrical pair of automobile engine hood hinges 1.

[0074] In this embodiment, the above-mentioned rack unit 2 includes a workbench 21 and an upright bracket 22, the above-mentioned upright bracket 22 is connected to the above-mentioned workbench 21, the above-mentioned positioning unit 3, the above-mentioned first detection unit 5 and the above-mentioned second detection unit 6 are installed on the above-mentioned workbench 21, and the above-mentioned toggle unit 4 is installed on the above-mentioned upright bracket 22.

[0075] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
