[0040] Please also read Figure 1 and Figure 2The present embodiment provides a detection device, which is used to detect an inclined surface 21 to be detected on a workpiece 20, and includes a bearing assembly 11, a detection bracket 12 and a detection assembly 13. The workpiece 20 is positioned and fixed on the bearing assembly 11. Specifically, the workpiece 20 is a C shell of a notebook shell. It can be understood that the ABCD shells of the notebook are the main components of the notebook shell, wherein the A shell refers to the back cover of the screen, the B shell refers to the front frame of the screen, the C shell refers to the upper cover of the host, and the D shell refers to the lower cover of the host. In the assembly production of the notebook shell, the D shell is usually screwed to the C shell. Due to the contour of the D shell of the notebook, the screw holes on the D shell are all on an inclined surface. The threaded column on the C part matches the screw hole on the D part. The end face of the threaded column needs to be designed as an inclined surface, and a threaded hole 22 for locking the screw along the normal direction of the inclined surface is opened on the inclined surface, so that the D can be screwed to the C shell. In order to ensure the assembly accuracy between the D shell and the C shell, the size of the inclined surface on the threaded column on the C part (for example, the inclination of the inclined surface, the height of the highest point and the lowest point) needs to be controlled. The existing detection method is direct measurement, resulting in low detection efficiency.

[0041] Please also read Figure 2 and Figure 3 The present embodiment provides a detection device, which is used to detect an inclined surface 21 to be detected on a workpiece 20, and includes a bearing assembly 11, a detection bracket 12 and a detection assembly 13. The bearing assembly 11 is used to carry and position the workpiece 20. The detection bracket 12 has an inclined reference inclined surface 121. The detection assembly 13 includes a detection rod 131. The detection rod 131 is slidably connected to the detection bracket 12 in a direction perpendicular to the reference inclined surface 121. One end of the detection rod 131 is used to abut against the inclined surface 21 to be detected. A detection mark 132 is provided on the side wall of the detection rod 131. The detection rod 131 is driven by an external force to move to abut against the inclined surface 21 to be detected. When the detection mark 132 moves to the plane where the reference inclined surface 121 is located, the inclined surface 21 to be detected is qualified.

[0042] In the above-mentioned detection device, the detection rod 131 is pushed by external force to slide in a direction perpendicular to the inclined surface to be detected, so that one end of the detection rod 131 is against the inclined surface to be detected. When the detection mark 132 moves to the plane where the reference inclined surface 121 is located, it means that the inclined surface 21 to be detected is qualified. When the detection mark 132 does not move to the plane where the reference inclined surface 121 is located, it means that the inclined surface 21 to be detected is unqualified. In this way, by pushing the detection rod 131 to move it to abut against the inclined surface 21 to be detected, it is observed whether the detection mark 132 on the detection rod 131 moves to the plane where the reference inclined surface 121 is located, so as to judge whether the inclined member is qualified, so that the detection process is convenient and fast, and saves time and effort, thereby improving the detection efficiency.

[0043] In this embodiment, the number of the detection bracket 12, the detection component 13 and the inclined surfaces 21 to be measured on the workpiece 20 is the same and multiple, and the detection bracket 12 and the detection component 13 are grouped to correspond to one of the inclined surfaces 21 to be measured, so as to facilitate the simultaneous detection of multiple inclined surfaces 21 to be measured, thereby improving the detection efficiency.

[0044] Please also read Figure 3 and Figure 4 In some embodiments, the detection mark 132 is an annular mark, and the center line of the annular mark is colinear with the center line of the detection rod 131. By designing the detection mark 132 as an annular mark surrounding the detection rod 131, it is convenient to judge whether the inclined surface 21 to be tested is qualified by observing the annular mark at any angle, thereby improving the convenience of detection, and the detection mark 132 is recessed in the detection rod 131 to prevent the detection mark 132 from interfering with the sliding movement of the detection rod 131 on the detection bracket 12. Specifically, the cross-sectional shapes of the detection mark 132 and the detection rod 131 are both circular.

[0045] In some embodiments, the width of the detection mark 132 is the same as the size of the normal tolerance zone of the inclined surface 21 to be measured. Specifically, the width of the detection mark 132 is adjusted according to the size of the normal tolerance zone of the inclined surface 21 to be measured.

[0046] During the test, when the end of the detection rod 131 is against the bevel 21 to be tested, the reference bevel 121 is located within the width interval of the detection mark 132, and the bevel 21 to be tested is qualified; when the reference bevel 121 is not within the width interval of the detection mark 132, the bevel 21 to be tested is unqualified; when the machining error of the reference bevel 121 is zero, the reference bevel 121 is located on the median line of the width interval of the detection mark 132 (i.e., the middle position of the width interval);

[0047] When the width of the detection mark 132 is equal to the normal tolerance zone size of the inclined surface 21 to be measured, when the machining accuracy of the inclined surface 21 to be measured exceeds the error range, the reference inclined surface 121 will not be within the width range of the detection mark 132, thereby improving the detection accuracy; when the width of the detection mark 132 is greater than the normal tolerance zone size of the inclined surface 21 to be measured, when the machining accuracy of the inclined surface 21 to be measured exceeds the error range, the reference inclined surface 121 will still be within the width range of the detection mark 132, resulting in a decrease in detection accuracy; when the width of the detection mark 132 is less than the normal tolerance zone size of the inclined surface 21 to be measured, when the machining accuracy of the inclined surface 21 to be measured is still within the error range, the reference inclined surface 121 will leave the width range of the detection mark 132, resulting in a decrease in detection accuracy.

[0048] In this way, by controlling the machining error of the inclined surface 21 to be measured during the detection, the detection accuracy of the inclined surface 21 to be measured is greatly improved.

[0049] In this embodiment, the detection mark 132 is processed by laser engraving to ensure the accuracy of the width dimension of the detection mark 132 .

[0050] It can be understood that the normal tolerance zone of the measured bevel 21 refers to the sum of the upper limit size and the lower limit size allowed along the normal direction of the measured bevel 21 when the measured bevel 21 is processed. For example, if the normal processing error of the measured bevel 21 is ±0.5mm, then the size of the normal tolerance zone of the measured bevel 21 is 1mm.

[0051] See also Figure 3 In some embodiments, a sliding hole 122 is provided on the reference inclined plane 121, and the sliding hole 122 penetrates the detection bracket 12 in a direction perpendicular to the reference inclined plane 121, and the detection rod 131 is slidably provided in the sliding hole 122; specifically, the cross-sectional shape and size of the detection rod 131 are the same as the cross-sectional shape and size of the sliding hole 122; in this way, the detection rod 131 is guided to move through the sliding hole 122, so that the movement path of the detection rod 131 during the sliding process remains stable, and always moves along the extension direction of the sliding hole 122, thereby calmly improving the detection accuracy of the detection rod 131.

[0052] Furthermore, the cross sections of the sliding hole 122 and the detection rod 131 are both circular structures.

[0053] See also Figure 3 In some embodiments, the detection assembly 13 further includes a first stopper 133 and a first elastic member 134, wherein the first stopper 133 is connected to the other end of the detection rod 131, the first elastic member 134 is sleeved on the detection rod 131, and one end of the first elastic member 134 abuts against the first stopper 133, and the other end of the first elastic member 134 abuts against the detection bracket 12. Exemplarily, the first elastic member 134 may be a spring.

[0054] In this way, when the detection rod 131 is driven by external force to move toward the inclined surface 21 to be tested, the detection rod 131 compresses the first elastic member 134 through the first stop member 133. When the external force is removed, the elastic force released by the first elastic member 134 drives the first stop member 133 to drive the detection rod 131 to automatically reset, so that the detection rod 131 can perform the next detection action.

[0055] See also Figure 3 In some embodiments, the detection assembly 13 also includes a second stopper 135, which is connected to one end of the detection rod 131 facing the inclined surface 21 to be detected. The second stopper 135 is clamped on the detection rod 131 and is used to prevent the detection rod 131 from detaching from the detection bracket 12 along the sliding hole 122.

[0056] Please also read Figure 1 and Figure 3In some embodiments, a threaded hole 22 is formed on the measured inclined surface 21, and the axis of the threaded hole 22 is perpendicular to the measured inclined surface 21. The detection component 13 also includes a pin 136 connected to one end of the detection rod 131, and the axis of the pin 136 is perpendicular to the reference inclined surface 121. The pin 136 is used to be inserted into the threaded hole 22.

[0057] During detection, the detection rod 131 is driven by external force to move toward the inclined surface 21 to be tested, and the detection rod 131 drives the pin 136 to be inserted into the threaded hole 22. Usually, the extension direction of the threaded hole 22 is perpendicular to the inclined surface 21 to be tested. When the operator feels an obvious blockage while holding the driving detection rod 131, it means that the inclined surface 21 to be tested is unqualified, thereby realizing the detection of the threaded hole 22 and the inclined surface 21 to be tested.

[0058] Please also read Figure 1 and Figure 2 In some embodiments, a positioning hole 23 is opened on the workpiece 20, and the supporting assembly 11 includes a supporting member 111 and a positioning member 112. The supporting member 111 is used to support the workpiece 20. The positioning member 112 is connected to one side of the supporting member 111 and is adapted to the positioning hole 23. The positioning member 112 is inserted into the positioning hole 23 to position the workpiece 20.

[0059] In this embodiment, the number of positioning members 112 and positioning holes 23 is the same and both are multiple, and the cross-section and size of the positioning members 112 are the same as the cross-section and size of the positioning holes 23; illustratively, the cross-section of the positioning members 112 is circular or polygonal.

[0060] See also Figure 2 In some embodiments, the detection device further includes a clamping assembly 14 , which is connected to the bearing assembly 11 and is used to clamp the workpiece 20 positioned on the bearing assembly 11 and to reduce the deformation of the workpiece 20 .

[0061] See also Figure 5In this embodiment, the clamping assembly 14 includes a plurality of fasteners 141, and the plurality of fasteners 141 are arranged at circumferential intervals with the center line of the workpiece 20 positioned on the bearing assembly 11 as the axis. Each fastener 141 includes a fixing member 1411, a resisting member 1412 and a second elastic member 1413. The fixing member 1411 is connected to the bearing assembly 11, and the fixing member 1411 is adjacent to the workpiece 20 positioned by the bearing assembly 11. One end of the resisting member 1412 is slidably connected to the fixing member 1411, and the other end of the resisting member 1412 is used to The second elastic member 1413 is sleeved on the fixing member 1411, one end of the second elastic member 1413 is in contact with the fixing member 1411, specifically, one end of the second elastic member 1413 is fixed to the fixing member 1411 by welding, the other end of the second elastic member 1413 is in contact with the supporting member 1412, specifically, the other end of the second elastic member 1413 is fixed to the supporting member 1412 by welding, and the elastic force released by the second elastic member 1413 is used to drive the supporting member 1412 to be pressed against the workpiece 20. Exemplarily, the second elastic member 1413 is a spring.

[0062] In this way, by arranging multiple groups of fasteners 141 at axial intervals with the center line of the workpiece 20 as the axis, and connecting them to the position of the supporting component 11 adjacent to the edge of the workpiece 20, the pressure generated when the multiple fasteners 141 press the workpiece 20 is more balanced, so as to reduce the deformation generated when the workpiece 20 is pressed, thereby eliminating the influence of the deformation of the workpiece 20 on the detection accuracy.

[0063] When the fastener 141 presses the workpiece 20, the elastic force released by the second elastic member 1413 drives the supporting member 1412 to press the workpiece 20. The second elastic member 1413 can be used to achieve flexible pressing of the workpiece 20 to avoid the wear of the workpiece 20 caused by hard pressing. Pressing the workpiece 20 by the fastener 141 saves time and effort, and is convenient and quick.

[0064] See also Figure 2 In this embodiment, the clamping assembly 14 further includes a locking member 142, which is connected to the bearing assembly 11 and is used to lock the workpiece 20 positioned on the bearing assembly 11, so as to further lock and fix the workpiece 20. Exemplarily, the locking member 142 can be a connecting rod type clamp or a clamp.

[0065] The working principle of the above detection device is roughly as follows:

[0066] First, the workpiece 20 is positioned on the carrier 111 through the positioning hole 23 and the positioning member 112 to achieve the positioning of the workpiece 20 in the horizontal direction. The carrier 111 is also used to position the workpiece 20 in the vertical direction, thereby achieving the positioning of the workpiece 20 in the three-dimensional direction;

[0067] Then, the workpiece 20 is locked and fixed by the locking member 142, and multiple positions of the workpiece 20 are compressed by multiple fasteners 141 to prevent the position of the inclined surface 21 to be measured on the workpiece 20 from changing due to local deformation of the workpiece 20, which may reduce the detection accuracy of the inclined surface 21 to be measured;

[0068] Finally, the operator manually drives the detection rod 131 to move it against the inclined surface 21 to be tested. When the reference inclined surface 121 is within the width range of the detection mark 132, the inclined surface 21 to be tested is qualified. When the reference inclined surface 121 is out of the width range of the detection mark 132, the inclined surface 21 to be tested is unqualified, and the detection efficiency and detection accuracy are higher.

[0069] The above is only a specific embodiment of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
