Description

Technical Field

[0001] The utility model relates to the technical field of airtightness detection, and particularly relates to a detection device. Background Art

[0002] The swing arm ball joint is an important component of an automobile. It bears the huge impact transmitted from the wheel end of the automobile and can provide rotational freedom. The precise structure of the swing arm ball joint makes it impossible to have any contamination such as mud and water inside, otherwise there will be risks such as looseness, abnormal noise, and loosening. Currently, usually, the position of the ball head pin relative to the swing arm pin seat is manually adjusted first, and then a liquid spraying gun is used to spray liquid on the swing arm ball joint at a position between 10 cm and 15 cm away from the swing arm ball joint. The above operation is repeated so that the ball head pin is sprayed at different positions relative to the swing arm pin seat. Finally, the swing arm ball joint is tested by an external special testing device based on set parameters to obtain whether the airtightness of the swing arm ball joint meets the set requirements.

[0003] However, in the above detection method, the parts where the swing arm ball joint contacts the liquid once are all parts of the local ball head pin, and the contact time between the swing arm ball joint and the liquid is short, resulting in low accuracy of the airtightness detection of the swing arm ball joint. Summary of the Utility Model

[0004] In view of the above, it is necessary to provide a detection device to improve the accuracy of the airtightness detection of the swing arm ball joint.

[0005] An embodiment of the utility model provides a detection device for detecting the airtightness of a swing arm ball joint. The swing arm ball joint includes a swing arm pin seat and a ball head pin. One end of the ball head pin is rotatably connected and embedded in the swing arm pin seat, and the other end of the ball head pin protrudes from the swing arm pin seat. The detection device includes:

[0006] A liquid storage tank provided with a storage tank for storing liquid;

[0007] A base disposed on the liquid storage tank and located in the storage tank. The base includes a mounting member and a guiding member. The swing arm ball joint is accommodated in the storage tank and is mounted on the mounting member through the swing arm pin seat;

[0008] The detection mechanism includes a fixed part, a movable part, a connecting part, a linkage part and a driving part, the fixed part is connected to the liquid storage tank, the movable part is slidably connected to the guide part along a first direction and is spaced apart from the mounting part along a second direction perpendicular to the first direction, the two ends of the connecting part are respectively connected to the other end of the ball pin and the movable part, one end of the linkage part is connected to the movable part, the driving part is arranged on the fixed part and connected to the end of the linkage part away from the movable part, and is used to drive the linkage part to drive the movable part to move along the first direction, so that the movable part drives the ball pin to move relative to the swing arm pin seat along the first direction through the connecting part.

[0009] In the above-mentioned detection device, the swing arm ball joint is accommodated in a storage groove, and liquids of different depths injected into the storage groove can cover different positions of the swing arm ball joint. After the liquid covers the target position of the swing arm ball joint, the driving part drives the linkage part to drive the movable part to move along the guide part, so that the movable part drives the ball head pin to move relative to the swing arm pin seat along the first direction through the connecting part, thereby realizing the sealing test of different positions of the swing arm ball joint in the liquid, expanding the test range of the swing arm ball joint, and increasing the contact time of the swing arm ball joint with the liquid, so that the accuracy of the sealing detection of the swing arm ball joint is improved.

[0010] In some embodiments, the guide member comprises:

[0031] In some embodiments, the fixing member further includes:

[0032] An extension body, connecting the bottom plate and extending to the storage groove;

[0052] The following will describe each embodiment of this case in detail with reference to the accompanying drawings.

[0053] Please refer to Figure 1 , Figure 1 FIG. is a schematic structural diagram of a swing arm ball joint adapted to the embodiment of the present utility model. Specifically, the swing arm ball joint 200 includes a swing arm pin seat 210 and a ball head pin 220. One end of the ball head pin 220 is rotatably connected and embedded in the swing arm pin seat 210, and the other end of the ball head pin 220 protrudes from the swing arm pin seat 210. Exemplarily, the swing arm ball joint 200 is applied to the suspension of an automobile to achieve the necessary degrees of freedom of movement when the wheels bounce and turn, and is also used to transmit various forces and torques from the road surface to the vehicle body.

[0054] For the convenience of description and explanation, a three-dimensional coordinate system is added to some of the drawings. Specifically, the Z-axis direction is the first direction, the X-axis direction is the second direction, and the Y-axis direction is the third direction. Among them, the X-axis direction, the Y-axis direction, and the Z-axis direction are perpendicular to each other in pairs.

[0055] Please refer to Figure 2 , the embodiment of the present utility model provides a detection device 100 for detecting the sealing performance of the swing arm ball joint 200. Specifically, the detection device 100 is used to detect the sealing performance of the ball head pin 220 relative to the swing arm pin seat 210. In the embodiment of the present utility model, the method for detecting the sealing performance is as follows: place the target position of the swing arm ball joint 200 in a liquid, drive the ball head pin 220 to rotate relative to the swing arm pin seat 210. After the above operations are completed, drive the swing arm ball joint 200 out of the liquid, and test the swing arm ball joint 200 by a testing device (not shown in the figure) based on set parameters, so as to obtain whether the sealing performance of the swing arm ball joint 200 meets the set requirements.

[0056] It should be noted that the detection device 100 in the embodiments of the present utility model realizes partial functions in the sealing detection of the swing arm ball hinge 200, specifically including the positioning of the swing arm ball hinge 200, the rotation of the ball head pin 220 relative to the swing arm pin seat 210, and placing the swing arm ball hinge 200 in a liquid. The specific structure of the detection device 100 will be described later. The specific test principle of the above test device for testing the swing arm ball hinge after it is taken out of the liquid based on set parameters can be directly obtained from the publicly available literature and will not be elaborated here.

[0057] Please refer to Figure 2 , the detection device 100 includes a liquid storage tank 110, a base 120, and a detection mechanism 130. The liquid storage tank 110 is provided with a storage tank 110a for storing liquid. Liquid can be transported into the storage tank 110a or pumped out of the storage tank 110a through an external water supply mechanism (not shown in the figure). Exemplarily, the liquid can be water or a specific detection liquid, and the water supply mechanism can be a water pump.

[0058] The base 120 is arranged on the liquid storage tank 110 and is located in the storage tank 110a. Specifically, the base 120 is located at the bottom of the storage tank 110a. The base 120 includes a mounting member 121 and a guiding member 122. The swing arm ball hinge 200 is accommodated in the storage tank 110a and is mounted on the mounting member 121 through the swing arm pin seat 210. Exemplarily, the swing arm pin seat 210 is detachably connected to the mounting member 121 through a pin.

[0059] Please refer to Figure 2 and Figure 3 , the detection mechanism 130 includes a fixing member 131, a movable member 132, a connecting member 133, a linkage member 134, and a driving member 135. The fixing member 131 is connected to the liquid storage tank 110. The movable member 132 is slidably connected to the guiding member 122 along the Z-axis direction and is spaced from the mounting member 121 along the X-axis direction. One end of the connecting member 133 is connected to the movable member 132. Specifically, one end of the connecting member 133 is sleeved on the movable member 132. The other end of the connecting member 133 is connected to the end of the ball head pin 220 away from the swing arm pin seat 210. One end of the linkage member 134 is connected to the movable member 132. The driving member 135 is arranged on the fixing member 131 and is connected to the end of the linkage member 134 away from the movable member 132. The driving member 135 is used to drive the linkage member 134 to drive the movable member 132 to move along the Z-axis direction, so that the movable member 132 drives the ball head pin 220 to move along the Z-axis direction relative to the swing arm pin seat 210 through the connecting member 133, thereby realizing the rotation of the ball head pin 220 relative to the swing arm pin seat 210. Exemplarily, the movable member 132 is a cylinder, and the axial direction of the movable member 132 is parallel to the Y-axis direction.

[0060] In this embodiment, there are multiple swing arm ball joints 200 and connectors 133, each swing arm ball joint 200 is installed on the mounting member 121 through a swing arm pin seat 210, multiple swing arm ball joints 200 are arranged at intervals along the Y-axis direction, and multiple connectors 133 are arranged at intervals along the Y-axis direction, and correspond to the multiple swing arm ball joints 200 one by one. Therefore, through the above arrangement, the detection device 100 can simultaneously realize the sealing detection of multiple swing arm ball joints 200, which is conducive to improving the detection efficiency of the detection device 100.

[0061] See also Figure 3 and Figure 4 In some embodiments, the guide member 122 includes a guide body 1221. The guide body 1221 includes a guide plate 1221a and a fixed plate 1221b. The guide plate 1221a is provided with guide holes 1221c and is spaced apart from the mounting member 121 along the X-axis direction. The movable member 132 is inserted into the two guide holes 1221c. The movable member 132 moves along the Z-axis direction under the guidance of the guide holes 1221c. The fixed plate 1221b is connected to the side of the guide plate 1221a away from the mounting member 121 and is installed on the slot wall of the storage slot 110a.

[0062] Therefore, the guide body 1221 is helpful to improve the stability of the movable member 132 moving along the Z-axis direction.

[0063] In this embodiment, the cross-sectional area of the fixing plate 1221b in the Y-axis direction gradually decreases in the direction away from the bottom wall of the storage slot 110a, so that the fixing plate 1221b has a structure with a wide bottom and a narrow top, which is beneficial to increase the firmness of the connection between the guide member 122 and the storage box 110.

[0064] In this embodiment, the shape of the fixed plate 1221b projected on the mounting member 121 along the X-axis direction is a trapezoid. It can be understood that in other embodiments, the shape of the fixed plate 1221b projected on the mounting member 121 along the X-axis direction can also be a triangle. In this embodiment, both guide bodies 1221 can be detachably mounted on the bottom wall of the storage slot 110a, which is conducive to setting the distance between the two guide bodies 1221 in the Y-axis direction based on the number of swing arm ball joints 200, which is conducive to improving the application range of the detection device 100.

[0065] In some embodiments, the guide member 122 includes at least two guide bodies 1221, at least two guide bodies 1221 are arranged at intervals along the Y-axis direction, and each guide body 1221 also includes a support plate 1221d. The support plate 1221d is installed on the bottom wall of the storage slot 110a, the mounting member 121 is mounted on at least two support plates 1221d, the guide plate 1221a is arranged on the support plate 1221d, and the fixing plate 1221b protrudes from the guide plate 1221a along the Z-axis direction and is connected to the support plate 1221d. Exemplarily, there are two guide bodies 1221.

[0066] Therefore, at least two guiding bodies 1221 can further improve the stability of the moving part moving in the Z-axis direction. In addition, the support plate 1221d facilitates the synchronous fixation of the mounting part 121 and the guiding bodies 1221 in the liquid storage tank 110, reducing the installation difficulty between the base 120 and the liquid storage tank 110.

[0067] In this embodiment, the height of the guiding plate 1221a relative to the support plate 1221d in the Z-axis direction is greater than the height of the fixing plate 1221b relative to the support plate 1221d in the Z-axis direction, which can provide sufficient moving distance for the moving part 132 in the Z-axis direction on the basis of meeting the firm connection between the guiding part 122 and the storage tank 110.

[0068] Please refer to Figure 4 , in some embodiments, the guiding hole 1221c penetrates through the guiding body 1221 in the Y-axis direction and includes a first arc segment 1221e, a straight segment 1221f and a second arc segment 1221g. The first arc segment 1221e, the straight segment 1221f and the second arc segment 1221g are arranged in sequence in the Z-axis direction, and both ends of the straight segment 1221f are respectively communicated with the first arc segment 1221e and the second arc segment 1221g.

[0069] Therefore, through the above settings, the guiding hole 1221c is generally a strip-shaped through hole with arc-shaped ends. On the one hand, it can prevent the guiding plate 1221a from colliding with the moving part 132 when guiding the moving part 132 to move in the Z-axis direction, thereby increasing the service life of the moving part 132. On the other hand, it can prevent the guiding plate 1221a from breaking due to the collision between the moving part 132 and the hole wall of the guiding hole 1221c when the moving part 132 moves in the Z-axis direction, thereby increasing the service life of the guiding plate 1221a.

[0070] In this embodiment, both the first arc segment 1221e and the second arc segment 1221g are generally in a U-shaped structure.

[0071] Please refer to Figure 2 and Figure 3 , in some embodiments, a liquid inlet 110b communicating with the storage tank 110a is provided at the top of the liquid storage tank 110. The fixing member 131 includes a bottom plate 1311, a mounting plate 1312 and a plurality of support columns 1313. The bottom plate 1311 is arranged on the liquid storage tank 110 and is erected on the liquid inlet 110b. The plurality of support columns 1313 are all connected to the side of the bottom plate 1311 facing away from the liquid storage tank 110 and are arranged at intervals along the circumferential direction of the bottom plate 1311. The mounting plate 1312 is respectively connected to the ends of the plurality of support columns 1313 far away from the bottom plate 1311, and the driving member 135 is arranged on the mounting plate 1312.

[0072] Therefore, multiple support columns 1313 are all connected between the mounting plate 1312 and the bottom plate 1311, forming a movable space between the mounting plate 1312 and the bottom plate 1311, which is convenient for the installation of related components.

[0073] It should be noted that the liquid inlet 110b is opened at the top of the liquid storage tank 110, which can provide sufficient liquid storage space for the storage tank 110a in the Z-axis direction, so that the liquid in the storage tank 110a can reach the maximum height in the Z-axis direction. In addition, since the liquid inlet 110b is opened at the top of the liquid storage tank 110, there is no need to install a capping structure at the liquid inlet 110b. When the external water supply mechanism can directly input and extract liquid through the liquid inlet hole 110b, the operation process of inputting and extracting liquid in the storage tank 110a can be simplified to improve the operation efficiency and reduce the manufacturing cost of the liquid storage tank 110.

[0074] In this embodiment, the mounting plate 1312 is generally square, and the number of support columns 1313 is four. The four support columns 1313 are respectively located at the four corner ends of the mounting plate 1312. It can be understood that in other embodiments, the mounting plate 1312 can also be of other shapes, and the number of support columns 1312 can also be three, five or more.

[0075] Please refer to Figure 3 , in some embodiments, the driving member 135 includes a driving body 1351 and a pushing and pulling body 1352. The driving body 1351 is arranged on the mounting plate 1312 and connected to the pushing and pulling body 1352. The pushing and pulling body 1352 is arranged between the mounting plate 1312 and the bottom plate 1311. There are multiple linkage members 134, and both ends of each linkage member 134 are respectively connected to the pushing and pulling body 1352 and the movable member 132. Exemplarily, the driving body 1351 is a cylinder. The main body of the driving body 1351 is installed on the side of the mounting plate 1312 facing away from the bottom plate 1311. The driving shaft of the driving body 1351 penetrates through the mounting plate 1312 along the Z-axis direction and extends between the mounting plate 1312 and the bottom plate 1311 to connect the pushing and pulling body 1352. The pushing and pulling body 1352 is generally in a strip structure, and the length direction of the pushing and pulling body 1352 is parallel to the Y-axis direction.

[0076] Therefore, through the above settings, the movable member 132 moves along the Z-axis direction driven by the multiple linkage members 134, which can avoid the shaking of the movable member 132 caused by uneven local stress, thereby improving the movement stability of the movable member 132.

[0077] In this embodiment, the number of linkage members 134 is two, and the two linkage members 134 are located on the opposite sides of the mounting plate 1312 in the Y-axis direction. It can be understood that in other embodiments, the number of linkage members 134 can also be three or more.

[0078] In some embodiments, the fixing member 131 further includes a bushing 1314. The bushing 1314 is fixedly inserted through the bottom plate 1311 and sleeved on the linkage member 134 to guide the linkage member 134 to slide along the Z-axis direction.

[0079] When the above detection device 100 is detecting an operation, a liquid of a certain height will be injected into the storage tank 110a. The movement of the linkage member 134 and the rotation of the ball head pin 220 relative to the swing arm ball hinge 210 will both cause the liquid in the storage tank 110a to sway in the plane formed by the X-axis direction and the Y-axis direction. The sway of the liquid will form a certain driving force on the linkage member 134 in at least one of the X-axis direction and the Y-axis direction. Through the above arrangement, the linkage member 134 and the bottom plate 1311 form an insertion structure, which can prevent the linkage member from swaying in the X-axis direction and the Y-axis direction, thereby improving the stability of the movement of the linkage member 134 along the Z-axis direction.

[0080] In some embodiments, the fixing member 131 further includes an extension body 1315 and a reinforcing plate 1316. The extension body 1315 is connected to the bottom plate 1311 and extends to the storage tank 110a. The reinforcing plate 1316 is connected to one end of the extension body 1315 away from the bottom plate 1311, and the bushing 1314 is embedded on the reinforcing plate 1316.

[0081] Therefore, through the above arrangement, there are a strip plate 1311b and a reinforcing plate 1316 which are spaced apart along the Z-axis direction between the movable member 132 and the mounting plate 1312, which can further increase the stability of the movement of the linkage member 134 along the Z-axis direction.

[0082] In some embodiments, the linkage member 134 includes a linkage column 1341 and a disassembly and assembly body 1342.

[0085] Therefore, through the above configuration, the manufacturing difficulty of the liquid storage tank 110 can be simplified and the manufacturing cost of the liquid storage tank 110 can be reduced.

[0086] Exemplarily, the light-transmitting member 112 is detachably connected to the main body 111 , so that the light-transmitting member 112 can be easily replaced.

[0087] In this embodiment, the positioning member 113 is substantially in the shape of a square body. A positioning hole 113 a is formed on the positioning member 113 . The positioning hole 113 a penetrates the positioning member 113 along the Z-axis direction.

[0088] See also Figure 3 and Figure 5 In some embodiments, the bottom plate 1311 includes a square plate 1311a and a strip plate 1311b. The square plate 1311a is disposed on the positioning member 113 and covers the positioning hole 113a.

Both ends of the strip plate 1311b along the Y-axis direction protrude from the square plate 1311a. Both ends of the strip plate 1311b protruding from the square plate 1311a along the Y-axis direction are provided with shaft sleeves 1314.

[0089] In this embodiment, the two shaft sleeves 1314 on the strip plate 1311b and the two shaft sleeves 1314 on the reinforcing plate 1316 correspond one to one in the Z-axis direction, the extension body 1315 passes through the positioning hole 113a to connect the side of the square plate 1311a away from the strip plate 1311b, and the reinforcing plate 1316 is provided with shaft sleeves 1314 at both ends along the Y-axis direction, and the two shaft sleeves 1314 on the reinforcing plate 1316 correspond one to one with the two linkage members 134. Among them, the linkage column 1341 is sequentially penetrated through the shaft sleeves 1314 on the square plate 1311a and the shaft sleeves 1314 on the reinforcing plate 1316 along the Z-axis direction.

[0090] The working process of the above detection device 100 in cooperation with an external dedicated test device is roughly as follows:

[0091] First, place the swing arm ball joint 200 into the storage groove 110a, and make the swing arm ball joint 200 connected to the mounting member 121 through the swing arm pin seat 210;

[0092] Then, catch the external water supply mechanism and inject the liquid with the required depth into the storage groove 110a through the liquid inlet 110b to cover the required detection position of the swing arm ball joint 200;

[0093] Subsequently, the driving member 135 drives the linkage member 134 to drive the moving member 132 to move along the guiding member 122, so that the moving member 132 drives the ball head pin 220 to move relative to the swing arm pin seat 210 in the Z-axis direction through the connecting member 133, so as to realize the rotation of the ball head pin 220 relative to the swing arm pin seat 210.

[0094] Finally, test the swing arm ball joint 200 based on the set parameters through an external special test device, so as to obtain whether the sealing performance of the swing arm ball joint 200 meets the set requirements.

[0095] It should be noted that the depth of the liquid injected into the storage groove 110a is different, and the position where the swing arm ball joint 200 is soaked by the liquid is different. By injecting liquids with different depths into the storage groove 110a, the sealing performance test of different positions of the swing arm ball joint 200 in the liquid can be realized.

[0096] Therefore, the above detection device 100 can realize the sealing performance test of different positions of the swing arm ball joint 200 in the liquid, expand the test range of the swing arm ball joint 200, and increase the contact time between the swing arm ball joint 200 and the liquid, so as to improve the accuracy of the sealing performance detection of the swing arm ball joint 200.
