DETAILED DESCRIPTION

[0029] To make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present application.

[0030] Please refer to Figure 1Some embodiments of this application provide a sealing channel testing fixture. The sealing channel includes a housing and a part to be tested 200. The housing has a reference surface 100. The distance between the thickness center of multiple parts to be tested 200 and the reference surface 100 is a predetermined value under standard working conditions. The sealing channel testing fixture includes a reference base 1 and a sliding rod 2. The reference base 1 includes a first detection surface 11 for conforming to the reference surface 100. The reference base 1 is provided with a positioning sliding groove 12. The sliding rod 2 can slide in the positioning sliding groove 12 and the distance between it and the first detection surface 11 remains unchanged when sliding.

[0031] By setting the reference base 1, this application can form a close fit with the reference surface 100 located on the sealing device, which facilitates obtaining a distant measurement reference, namely the first detection surface 11, at a greater distance from the sealing channel components. The sliding rod 2 can slide within the positioning sliding groove 12 and maintain a preset distance from the first detection surface 11 on the reference base 1. By sliding the sliding rod 2 to the vicinity of the part to be measured 200, it can be determined whether the distance between the part and the reference surface 100 meets the standard working condition. By rotating the reference base 1 and moving the sliding rod 2 within the positioning sliding groove 12, the sliding rod 2 can be used to measure multiple sealing channel components located at different positions.

[0032] The size of the preset value usually does not affect the implementation of this application. Specifically, the preset value is usually 33mm in the existing sealing channel.

[0033] In some embodiments, the reference base 1 further includes a fixing part 13 for fixing the first detection surface 11 to the reference surface 100. The fixing part 13, by fixing the reference surface 100 to the first detection surface 11, eliminates the need for manual application, reducing operational difficulty, saving manpower, and improving accuracy. The fixing method is not limited; for example, it can be fixed using a threaded connection with the mounting holes on the sealing device housing, or using a magnetic connection. Preferably, the fixing part 13 includes a strip-shaped through hole, within which a first connector 131 is provided. The sealing device housing has multiple mounting holes, and the first connector 131 connects to the mounting holes at different positions within the strip-shaped through hole, allowing adjustment of the relative position between the reference base 1 and the sealing device, providing high flexibility and eliminating the need for repeated disassembly and reassembly of the reference base 1.

[0034] To facilitate operators in observing the distance between the part to be tested 200 and the reference surface 100, in some embodiments, the sliding rod 2 is provided with an indicator part 23 that indicates the distance to the first detection surface 11, such as an indicator line or other structure that can indicate distance.

[0035] In some embodiments, the end of the sliding rod 2 comprises a positioning groove 21 with a size corresponding to the gasket channel component. Since the component to be measured 200 usually comprises a cam, a sector wheel, a bearing or other easily worn and deformed components, which have a certain thickness, the positioning groove 21 is arranged at the end of the sliding rod 2, and the component to be measured 200 can be placed in the positioning groove 21 during measurement. In addition to the distance being measured, the wear degree and the deviation degree of the component to be measured 200 can be observed by observing the distance between the component to be measured 200 and the groove wall.

[0036] In some embodiments, the sliding rod 2 comprises a sliding mounting hole 22, and a connecting piece is arranged in the sliding mounting hole 22. The connecting piece is connected with the positioning sliding groove 12 and can slide relative to the sliding mounting hole 22. The sliding mounting hole 22 and the connecting piece arranged on the sliding rod 2 can slidably connect the sliding rod 2 and the reference seat 1, so that the sliding rod 2 and the reference seat 1 do not need to be fixed by manpower, and the operation is simplified.

[0037] The reference seat 1 can be associated with the reference surface 100, and whether the component to be measured 200 such as the gasket cylinder is horizontal is an important requirement in production. In order to further enable the gasket channel detection tool to have the function of detecting whether the component to be measured 200 is perpendicular to the reference surface 100, in some embodiments, a first detection rod 3, a second detection rod 4 and a connecting rod 5 capable of keeping the first detection rod 3 and the second detection rod 4 parallel are further included, and the first detection rod 3 can be connected with the reference seat 1 perpendicularly to the first detection surface 11.

[0038] For example, the connecting rod 5 can have two parallel holes capable of being inserted and limited in the first detection rod 3 and the second detection rod 4, respectively.

[0039] During use, since the first detection rod 3 is perpendicular to the reference surface 100, and the connecting rod 5 can keep the second detection rod 4 parallel to the first detection rod 3, the rod body of the second detection rod 4 is always perpendicular to the reference surface 100. By moving the second detection rod 4 to the vicinity of the component to be measured 200, whether the component to be measured 200 is perpendicular to the reference surface 100 can be conveniently observed.

[0040] In some embodiments, the first detection rod 3 and the connecting rod 5 are relatively fixed by a locking screw 51. The locking screw 51 can improve the accuracy of the operation for judging whether the component to be measured 200 is horizontal, and reduce the error caused by human operation.

[0041] In some embodiments, the reference seat 1 comprises a second detection surface 14 parallel to the first detection surface 11, and the end surface of the first detection rod 3 is attached to the second detection surface 14. In this way, the first detection rod 3 and the reference seat 1 are arranged, which can make the function of detecting whether the component to be measured 200 is perpendicular to the reference surface 100 more convenient and easy to implement.

[0042] In some implementation scenarios, the part 200 has no structure outside the installation plane perpendicular to it, so it is difficult to observe its relationship with the second detection rod 4. Therefore, in some embodiments, a third detection rod 6 is arranged on the part 200, which is perpendicular to the second detection rod 4 when the part 200 is in a standard working state. For example, it can be parallel to the working direction of the part 200, or perpendicular to the installation plane.

[0043] The following will be described in detail Figures 1-4 with reference to a specific embodiment of the present application, i.e. a seal passage detection tool. It should be noted that Figures 1-4 the drawing is a schematic diagram, and the proportions are not necessarily strictly consistent with the actual product. For example, the length of the positioning sliding groove 12 should be relatively Figures 1-4 long in actual implementation to measure the part 200 at a farther distance. Other components of the seal passage device, including components that block conventional detection means such as a ruler, a vernier caliper, etc. between the part 200 and the reference surface, are not shown in the drawing. Figures 1-4

[0044] The embodiment is used to detect whether the thickness center of the part 200 on the seal passage is 33 mm away from the reference surface 100, and whether the seal glue cylinder on the seal passage is perpendicular to the reference surface 100. The part 200 includes a cam, a sector, a bearing, Figures 1-2 and the like, taking the cam as an example.

[0045] As Figures 1-5 shown in the drawing, the embodiment includes a reference seat 1 and a sliding rod 2, and further includes a first detection rod 3, a second detection rod 4 and a third detection rod 6 which are all cylindrical, and a connecting rod 5 which can keep the first detection rod 3 and the second detection rod 4 parallel.

[0046] As Figures 1-2 shown in the drawing, the sliding rod 2 is a strip-shaped cuboid, which is provided with a sliding installation hole 22 and a positioning groove 21 at an end, and the positioning groove 21 is provided with an indicating line as an indicating part 23 at the center.

[0047] As Figures 1-3 shown in the drawing, the reference seat 1 is cylindrical, the bottom surface is a first detection surface 11, the side surface is provided with a positioning sliding groove 12 which is consistent in size with the sliding rod 2, the center of the positioning sliding groove 12 is 33 mm away from the first detection surface 11, the groove bottom of the positioning sliding groove is further provided with a threaded hole 121, and a second connecting piece 122 is threadedly connected with the threaded hole 121 through the sliding installation hole 22, so as to slidably connect the sliding rod 2 in the positioning sliding groove 12. The reference seat 1 is provided with a fixing part 13 at the center, which is a strip-shaped through hole. The first connecting piece 131, which is a screw, is installed in the fixing part 13, so as to fix the reference seat 1 on the device shell where the reference surface 100 is located. ​

[0048] As Figures 1-3 When the cam, the sector wheel, the bearing on the sealing channel needs to be detected, the positioning sliding groove 12 is rotated to the position of the part 200 to be detected, the reference seat 1 is fixed on the reference surface 100, then the sliding rod 2 is put into the positioning sliding groove 12 and slides until the part 200 to be detected is in the positioning groove 21, then the screw in the sliding mounting hole 22 is installed, and whether the thickness center of the part 200 to be detected is aligned with the indicating part 23 is observed, and whether the distance between the two sides of the part 200 to be detected and the two side walls of the positioning groove 21 is equal is observed. When another part 200 to be detected is detected, the screw in the sliding mounting hole 22 is loosened, the sliding rod 2 is slid to adjust the distance, the reference seat 1 is rotated or re-installed to adjust the direction or position.

[0049] As Figures 4-5 The reference seat 1 is further provided with a detection hole 15 with a bottom surface parallel to the first detection surface 11, the bottom surface of the detection hole 15 is the second detection surface 14, the first detection rod 3 can be inserted into the detection hole 15 and the end surface of the first detection rod 3 is kept in contact with the second detection surface 14. The connecting rod 5 has two parallel holes which can be inserted into and limit the first detection rod 3 and the second detection rod 4 respectively, the first detection rod 3 and the second detection rod 4 are fixed relative to the connecting rod 5 through the locking screw 51, the end of the connecting rod 5 is provided with a through groove parallel to the screw hole on the connecting rod 5, so that the connecting rod 5 is deformed when the locking screw 51 is locked, and in this way, the locking screw 51 does not easily affect the parallel relationship between the two detection rods. The third detection rod 6 is arranged in the sealing glue cylinder through a shaft coupling and is parallel to the glue discharging direction of the sealing glue cylinder.

[0050] As Figures 4-5 When the sealing glue cylinder needs to be detected, the reference seat 1 is fixed on the reference surface 100, the first detection rod 3, the connecting rod 5 and the second detection rod 4 are sequentially installed, and the second detection rod 4 is near the third detection rod 6, and whether the second detection rod 4 and the third detection rod 6 are flush is observed.
