[0003] The existing assembled external water cutter is composed of an external water cutter body and an end cover. After the end cover is assembled with the external water cutter body, it is close to the end face of the external water cutter body.

[0047] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.

[0048] Reference Figures 1 to 3 In a first aspect, an embodiment of the present application provides an external water-cut end cap 100, which includes an embedded body 110, a cover body 120 and a docking body 130, wherein the cover body 120 is located at the end of the embedded body 110, the docking body 130 is arranged on the side of the embedded body 110 and extends outward along the width direction of the embedded body 110, and the docking body 130 can be compressed and deformed along the thickness direction of the embedded body 110.

[0049] When the outer water-cut end cover 100 of the present application is assembled with the outer water-cut body, the embedded body 110 is inserted into the end of the outer water-cut body. The embedded body 110 serves to strengthen the structural strength of the end of the outer water-cut body. After the embedded body 110 is pushed into place, the cover body 120 blocks the end face of the outer water-cut body, which serves as decoration and shielding. The docking body 130 is used to be connected with the door sheet metal. Before the docking body 130 is inserted into the door sheet metal, the guide groove at the corresponding position of the door sheet metal can compress the docking body 130 to a set thickness, so that the docking body 130 can enter the clamping position of the door sheet metal and clamp the door sheet metal, thereby realizing that the outer water-cut end cover 100, the outer water-cut body and the door sheet metal are connected as one, firmly and reliably, and no additional process is required for assembly and fixation, thereby greatly improving the assembly production efficiency of the door.

[0050] On the one hand, the setting position of the docking body 130 does not affect the rapid assembly of the outer water-cut end cover 100 and the outer water-cut body. Only a simple insertion action is required to achieve rapid assembly and fixation with the outer water-cut end cover 100. In addition, the docking body 130 can be deformed, which is also convenient for rapid assembly with the door sheet metal. The overall assembly is convenient. The structurally optimized outer water-cut end cover 100 is conducive to the automated assembly of the assembled outer water-cut, which facilitates the promotion of automated production.

[0051] Compared with the existing external water-cut end cap 100, the external water-cut end cap 100 of the present application has a simple structure and no complex structural setting, which makes injection molding convenient and reduces the difficulty of developing injection molds. Reducing complex structural design is conducive to ensuring injection molding yield, and subsequent finished product testing is also convenient without the need for excessive size and shape testing.

[0052] It should be noted that, in order to adapt to the optimization and modification of the external water-cut end cover 100, the relevant structure of the external water-cut body is also optimized so that the two are compatible.

[0053] In some embodiments, the embedding body 110 is in a straight strip shape, which is easy to detect and has no complicated design, making assembly more convenient.

[0054] In some embodiments, the shape of the cover 120 is adapted to the end surface shape of the external water-cut body, and after the external water-cut end cover 100 of the present application is assembled with the external water-cut body, the cover 120 fits and blocks the end surface of the external water-cut body.

[0055] In some embodiments, the docking body 130 includes a receiving cavity 132 and two engaging portions 131, one end of the engaging portion 131 is fixed to the receiving cavity 132, the other end of the engaging portion 131 is exposed outside the receiving cavity 132, and the opening direction of the receiving cavity 132 is parallel to the thickness direction of the embedded body 110. Under the action of external force, the engaging portion 131 can be pressed to deform and be received in the receiving cavity 132, so as to reduce the thickness of the docking body 130 along the thickness direction of the embedded body 110, and facilitate the assembly of the docking body 130 and the door sheet metal.

[0056] In some specific embodiments, the locking portion 131 is fixed to the side of the accommodating cavity 132 away from the embedded body 110, and the locking portion 131 is inclined toward the outside of the accommodating cavity 132 to form a guiding inclined surface structure on the side of the docking body 130 away from the embedded body 110, and under the action of external force, the locking portion 131 can be compressed, and the locking portion 131 can also be locked with the locking groove set in the door sheet metal.

[0057] In some embodiments, in order to make the connection between the docking body 130 and the door sheet metal more firmly, two engaging parts 131 are provided, and the two engaging parts 131 are staggered so that both engaging parts 131 can be simultaneously accommodated in the accommodating cavity 132, and the accommodating cavity 132 runs through both sides of the docking body 130. Specifically, the accommodating cavity 132 runs through both sides of the docking body 130 in a direction parallel to the thickness direction of the embedding body 110, and the free ends of the two engaging parts 131 are respectively exposed on both sides of the docking body 130. The two engaging parts 131 located on different sides can achieve effective engagement (although it is not shown how the docking piece is engaged with the door sheet metal, the door sheet metal is provided with a slot.).

[0058] In some embodiments, the side of the embedded body 110 along the length direction is bent with a connecting portion 114, the connecting portion 114 extends to connect with the cover body 120, and the connecting portion 114 is used to snap with the outer water-cut body. The connecting portion 114 is arranged on the side of the embedded body 110, which can not only strengthen the structural strength of the entire outer water-cut end cover 100, but also can make the embedded body 110 snap into the outer water-cut body through the connecting portion 114 to complete the connection.

[0059] In some embodiments, a limiting portion 115 is provided in the middle portion of the embedded body 110 along the width direction, and the limiting portion 115 extends along the length direction of the embedded body 110 to dock with the cover body 120. The limiting portion 115 and the connecting portion 114 are on the same side, so that the thickness of the entire embedded body 110 can be made smaller while also having a certain structural strength. The limiting portion 115 is used to position and limit the embedded body 110, and the limiting portion 115 cooperates with the groove structure inside the outer water-cut body to prevent the embedded body 110 from detaching from the side of the outer water-cut body.

[0060] In some embodiments, it should be noted that a snap-in groove is provided on the external water-cut body, and a snap-in protrusion 111 is provided on the embedded body 110. The snap-in protrusion 111 is used to connect with the snap-in groove, and cooperates with the design of the connecting portion 114 to position and fix the embedded body 110 at the end position of the external water-cut body. In the embodiment of the present application, the snap-in protrusion 111 and the limiting portion 115 are respectively located on both sides of the embedded body 110.

[0061] In some embodiments, the embedded body 110 is provided with a through hole 112 , and the opening direction of the through hole 112 is along the thickness direction of the embedded body 110 , and the through hole 112 is used to connect with the convex connection piece on the outer water-cut body.

[0062] The cooperation between the convex part and the through hole 112, and the cooperation between the limiting part 115 and the groove structure inside the outer water-cut body, can prevent the embedded body 110 from detaching from the side of the outer water-cut body.

[0063] like Figures 4 to 10 As shown, the second embodiment of the present application further provides a gauge for an external water-cut end cap 100, the gauge comprising a gauge body 200, a first detection surface 210 and a second detection surface 260 are respectively provided at both ends of the gauge body 200, a detection channel 220 is provided between the first detection surface 210 and the second detection surface 260, a third detection surface 230 and a measuring guide groove 240 are provided at a position of the detection channel 220 close to the first detection surface 210, and a detection groove 250 penetrating the detection channel 220 is provided on the side of the gauge body 200.

[0064] The first detection surface 210 is used to detect the end surface of the cover body 120 , and the first detection surface 210 cooperates with the third detection surface 230 to detect the thickness of the cover body 120 .

[0065] The first detection surface 210 cooperates with the second detection surface 260 to detect the length dimension of the external water-cut end cap 100 .

[0066] The detection channel 220 is used to measure the shape of the embedded body 110 .

[0067] The detection groove 250 is used to detect the appearance of the docking body 130 .

[0068] The shape of the third detection surface 230 is adapted to the shape of the cover body 120 .

[0069] Specifically, during the inspection, part of the shape of the inspection channel 220 is adapted to the shape of the embedded body 110, and the remaining part of the inspection channel 220 is used to avoid the docking body 130. The inspection channel 220 is used to detect whether the outer contour dimensions of the embedded body 110 meet the preset standards. The inspection is rapid. If the embedded body 110 cannot be placed in the inspection channel 220, the size of the embedded body 110 or the docking body 130 is unqualified, that is, the size of the external water-cut end cover 100 is unqualified, and there is no need for subsequent measurement and inspection.

[0070] The embedded body 110 is placed into the detection channel 220 and the cover body 120 is brought into contact with the third detection surface 230. The distance between the first detection surface 210 and the third detection surface 230 is the preset standard thickness of the cover body 120. After the cover body 120 is brought into contact with the third detection surface 230, it is detected by touch or direct observation. If the end surface of the cover body 120 is higher or lower than the first detection surface 210, the thickness dimension of the cover body 120 is unqualified, that is, the dimension of the external water-cut end cap 100 is unqualified, and no subsequent measurement and detection is required.

[0071] Furthermore, in order to detect the flatness of the end surface of the cover body 120, the segment gauge 400 can be used in conjunction with the first detection surface 210. Specifically, the segment gauge 400 is placed on the first detection surface 210, and the detection head of the segment gauge 400 is against the end surface of the cover body 120. The segment gauge 400 is translated on the first detection surface 210, and the range of change of the dial indicator or digital display on the segment gauge 400 is used to confirm whether the flatness of the end surface of the cover body 120 meets the requirements. If the flatness of the end surface of the cover body 120 is unqualified, that is, the size of the outer water-cut end cover 100 is unqualified, no subsequent measurement and detection is required.

[0072] Among them, the step difference gauge 400 is a tool used to measure and detect the unevenness of the surface of an object. It is mainly used for the detection of step difference and face difference in the fields of mold manufacturing and automobile production. Step difference refers to the matching deviation of the position of the parting surface of two mold inserts or front and rear molds due to the deviation in processing accuracy, while face difference refers to the uneven joint between the surfaces when the parts are assembled, which feels rough and scratchy. The step difference gauge 400 mainly has the following types: vernier caliper step difference gauge 400, digital display step difference gauge 400, and two-ball step difference gauge 400.

[0073] In addition, after the cover body 120 abuts against the third detection surface 230, the length of the outer water-cut end cap 100 is detected by touching the detection areas corresponding to the first detection surface 210 and the second detection surface 260 to see if there are protrusions or depressions. Specifically, slide the finger along the first detection surface 210, if it is detected that the cover body 120 protrudes from the first detection surface 210, or slide the finger along the second detection surface 260, if the second detection surface 260 detects that the embedded body 110 protrudes from the second detection surface 260, then the size of the outer water-cut end cap 100 does not meet the preset requirements, and no subsequent detection is required.

[0074] The inspection pass standard for the external water-cut end cap 100 that meets the size requirements is: the end face of the cover body 120 is level with the first inspection surface 210, and the end of the embedded body 110 is level with the second inspection surface 260. All other conditions are unqualified. The inspection is convenient and intuitive, and can effectively improve the inspection efficiency.

[0075] When the inspection of the cover body 120 and the inspection of the embedded body 110 are completed and both meet the standards, the needle gauge 300 is inserted into the inspection channel 220, and the end face size of the docking body 130 from the cover body 120 is measured by the needle gauge 300 to see whether it meets the standards. If not, the external water-cut end cover 100 does not meet the standards.

[0076] A visual inspection is used to check whether the docking body 130 can be viewed through the detection slot 250. If the docking body 130 cannot be viewed through the detection slot 250, the outer contour size of the docking body 130 is unqualified; when the docking body 130 can be viewed from the detection slot 250, the needle gauge 300 is inserted from the detection slot 250 and slides along the inner wall of the detection slot 250. If the needle gauge 300 cannot pass through one side of the inspection tool body 200 or cannot slide along the inner wall of the detection slot 250, the outer contour size of the docking body 130 is too large and does not meet the standard.

[0077] Among them, the pin gauge 300 is a round bar with a specific size and high hardness made of white steel, tool steel, ceramic, tungsten steel bearing steel or other materials. The pin gauge 300 is suitable for measuring the hole diameter, hole spacing, and internal thread minor diameter in mechanical and electronic processing, and is particularly suitable for measuring the bending groove width and mold size. It is used to check the position, measure the size of the hole, check the distance between the two holes, and can also be used as a go gauge and measure the depth of the hole. It is an essential inspection tool for standardized hole inspection, and uses an internationally advanced laser detector to inspect the workpiece.

[0078] The inspection tool of the present application first inspects the embedded body 110, then inspects the length dimension of the outer water-cut end cover 100 or the related dimensions of the cover body 120, and finally inspects the related dimensions of the docking body 130, thereby avoiding invalid inspection and effectively improving the inspection efficiency.

[0079] In some embodiments, the measuring guide groove 240 is provided at a position of the detection channel 220 close to the first detection surface 210, and the measuring guide groove 240 is arranged around the edge of the third detection surface 230. The setting of the detection groove 250 facilitates the detection of the outer contour of the cover body 120, because the cover body 120 that meets the standard is flush with the first detection surface 210. When the outer contour of the cover body 120 needs to be detected, a simple method is to check whether the outer contour of the cover body 120 coincides with the third detection surface 230. If the outer contour of the cover body 120 coincides with the third detection surface 230, it meets the standard; if not or the outer contour of the cover body 120 is larger than the third detection surface 230, the needle gauge 300 is slid along the groove wall of the measuring guide groove 240 for one circle. If the needle gauge 300 can slide, the outer contour of the cover body 120 meets the standard.

[0080] In some embodiments, a first detection surface 210, a third detection surface 230, a detection channel 220 and a detection slot 250 can be used in conjunction with a second detection surface 260 to detect an external water-cut end cap 100. When more than two external water-cut end caps 100 need to be detected, more than two first detection surfaces 210, third detection surfaces 230, detection channels 220 and detection slots 250 can be set on the inspection fixture body 200.

[0081] In some embodiments, the present application further provides a method for detecting the external water-cut end cap 100. Based on the above-mentioned inspection tool, the specific steps are as follows:

[0082] Put the embedded body 110 into the detection channel 220 and make the cover body 120 abut against the third detection surface 230, and measure the length of the outer water-cut end cap 100 by touching the first detection surface 210 and the second detection surface 260;

[0083] The flatness of the end surface of the cover body 120 and the thickness of the cover body 120 are measured by using the segment gauge 400 in cooperation with the first measuring surface;

[0084] Measure the outer contour size of the cover body 120 by direct observation or by using the pin gauge 300 in conjunction with the third measuring surface;

[0085] Measure the end surface dimension of the docking body 130 from the cover body 120 by using a pin gauge 300;
