Description

Technical Field

[0001] The utility model relates to the technical field of vehicle inspection tools, in particular to a hinge coaxiality inspection device. Background Art

[0002] During the vehicle production process, the door and the body need to be assembled and connected through hinges. The installation process of the door is usually to assemble the hinge to the white body in the welding workshop first, and then to the final assembly workshop after spraying in the painting workshop. In the final assembly workshop, the door sheet metal needs to be removed from the hinge axis position, and the door interior panels, glass, lifters and other parts need to be installed on the door sheet metal. Finally, the door assembly is installed back to the body.

[0003] Due to factors such as the tolerance of the hinges themselves, stress release during the disassembly process, and operator errors, the coaxiality of the upper and lower hinges of the car body can be easily affected, resulting in the inability to quickly and accurately install the body assembly to the body, affecting the production rhythm, the accuracy of the body and the side panel, and even causing problems such as line stoppage and rectification. Therefore, it is necessary to detect the coaxiality of the upper and lower hinges of the car body and make timely adjustments. Utility Model Content

[0004] In view of the above problems, the utility model provides a hinge coaxiality detection device, which can quickly detect the coaxiality of two vehicle body hinges and provide an operating basis for operators to adjust the vehicle body hinges, so as to facilitate subsequent rapid and accurate installation of vehicle doors.

[0005] The utility model provides a hinge coaxiality detection device, which is used to detect the coaxiality of a vehicle body hinge. The vehicle body hinges are two and arranged vertically opposite to each other, and each of the vehicle body hinges is provided with a hinge hole. The hinge coaxiality detection device comprises: a shell, which is fixed on one of the two vehicle body hinges; a laser emitting component, which is arranged on the shell, and is configured to emit a laser beam, and the laser beam is coaxial with the hinge hole of the vehicle body hinge where the shell is located, and the laser beam is suitable for passing through the hinge hole of the vehicle body hinge where the shell is located, and emitting to the hinge hole of the other vehicle body hinge.

[0006] According to the hinge coaxiality detection device of the utility model, a laser beam is emitted through a laser emitting member. While ensuring that the laser beam is coaxial with the hinge hole of one of the body hinges, the laser beam is emitted to the hinge hole of the other body hinge, thereby detecting the coaxiality of the two body hinges according to whether the laser beam can pass through the hinge holes of the two body hinges at the same time, thereby providing an operating basis for the operator to adjust the body hinge, so as to facilitate the subsequent rapid and accurate installation of the door, and solve the problem of the lack of hinge coaxiality detection affecting the production rhythm, and the detection performance is reliable, the detection principle is relatively simple, and it is easy to implement. In addition, compared with the solution of using a detection pin rod to detect the hinge coaxiality in the related art, it can save the inconvenience of manual operation, improve the detection efficiency, and also avoid the deformation of the detection pin rod affecting the detection accuracy.

[0007] In some embodiments, the laser emitting element is configured to emit a laser beam with multiple light characteristics, wherein the light characteristics include at least one of a diameter of the laser beam, a line shape of the laser beam, and a color of the laser beam.

[0008] In this way, the application scope of the hinge coaxiality detection device of this embodiment can be improved, and it can adapt to the hinge coaxiality detection needs under more vehicle models and more detection conditions, and has better practicality.

[0009] In some embodiments, a configuration port is provided on the housing, the configuration port is communicatively connected with the laser emitting element, and the configuration port is used to configure the optical characteristics of the laser beam.

[0010] In this way, laser beams with different light characteristics are configured for the hinge coaxiality detection device according to different vehicle models, so that the same set of hinge coaxiality detection device can be applied to the hinge coaxiality detection needs of various vehicle models, thereby expanding the scope of use. Compared with the solution of developing more than two sets of detection pins for each vehicle model in the related technology, it can greatly reduce the detection cost and the detection accuracy is easier to ensure.

[0011] In some embodiments, the configuration port is used to configure a first laser beam and a second laser beam for the laser emitting element in a single configuration operation, the first laser beam has a first diameter, and the first diameter is the upper limit value of the aperture of the hinge hole, the second laser beam has a second diameter, and the second diameter is the lower limit value of the aperture of the hinge hole, and the hinge coaxiality detection device detects the coaxiality of the body hinge through the first laser beam and the second laser beam respectively.

[0012] This is helpful to improve the accuracy of the detection results.

[0013] In some embodiments, a switch button is provided on the housing, the switch button is electrically connected to the laser emitting element, and the switch button is configured to control the laser emitting element to switch the first laser beam and the second laser beam when triggered.

[0014] In this way, by setting a switch button, the laser beam emitted by the laser emitting element can be flexibly switched to respectively use the first laser beam and the second laser beam to perform coaxiality detection, thereby improving the accuracy of the detection result.

[0015] In some embodiments, the shell is stacked on the side of one of the body hinges facing away from the other body hinge, and the hinge coaxiality detection device also includes: a fixing part, which is arranged on the side of the shell facing the body hinge, and the fixing part is used to fix the shell to the body hinge.

[0016] By setting a fixing part and fixing the shell to the hinge of the vehicle body, a stable support effect can be provided for the laser emitting part, ensuring its stable position during the detection process, so as to improve the accuracy of the detection result.

[0017] In some embodiments, the fixing member is a magnetic member, and the fixing member is magnetically matched with the vehicle body hinge.

[0018] In this way, the matching mode between the fixing part and the vehicle body hinge is relatively simple, low in cost and easy to implement.

[0019] In some embodiments, a mounting groove is provided on a side of the shell facing the vehicle body hinge, and the fixing member is embedded in the mounting groove.

[0020] In this way, the installation method of the fixing member on the housing and the structure of the housing itself are relatively simple and easy to assemble.

[0021] In some embodiments, the hinge coaxiality detection device also includes: a coaxiality positioning frame, the coaxiality positioning frame is arranged on the side of the shell facing the body hinge, the projection of the coaxiality positioning frame in the reference plane is within the projection of the hinge hole in the reference plane, and the reference plane is perpendicular to the axis of the hinge hole.

[0022] In this way, the coaxiality positioning frame can be placed in the hinge hole to ensure that the laser beam emitted by the laser emitting component is coaxial with the hinge hole of the vehicle body hinge. In this way, after the laser beam passes through the hinge hole of the hinge on the vehicle body, it can be shot to the hinge hole of the hinge under the vehicle body to detect the coaxiality of the hinge under the vehicle body and the hinge on the vehicle body.

[0023] In some embodiments, the coaxial positioning frame includes a plurality of positioning feet, and the outer sides of the projections of the plurality of positioning feet in the reference plane are located on the same reference circle, and the diameter of the reference circle corresponds to the inner diameter of the hinge hole.

[0024] In this way, when the coaxiality positioning frame is extended into the hinge hole, it can prevent the hinge coaxiality detection device from being radially displaced relative to the body hinge, which will cause the laser emitting component and the hinge hole of the body hinge to be not in a coaxial state, which is not conducive to improving the reliability of the detection result.

[0043] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0044] During the vehicle production process, the doors and the body need to be assembled and connected through hinges. The installation process of the door is usually to first assemble the hinges to the white body in the welding workshop, and then pass through the painting workshop for spraying and then flow to the general assembly workshop. In the general assembly workshop, the door sheet metal needs to be removed from the hinge axis position, and the door interior panels, glass, lifters and other parts are installed on the door sheet metal. Finally, the door assembly is installed back to the body. Due to factors such as the tolerance of the hinge itself, the stress release during the disassembly process, and the operator's error, the coaxiality of the upper and lower hinges of the body is easily affected, resulting in the body assembly cannot be quickly and accurately installed on the body, affecting the production rhythm, affecting the accuracy of the body and the side perimeter, and even causing problems such as stopping the line for rectification. Therefore, it is necessary to detect the coaxiality of the upper and lower hinges of the body and make timely adjustments.

[0045] In view of this, the utility model provides a hinge coaxiality detection device, which emits a laser beam through a laser emitting component. While ensuring that the laser beam is coaxial with the hinge hole of one of the body hinges, the laser beam is emitted to the hinge hole of the other body hinge, so as to detect the coaxiality of the two body hinges according to whether the laser beam can pass through the hinge holes of the two body hinges at the same time, thereby providing an operating basis for the operator to adjust the body hinges, so as to facilitate the subsequent rapid and accurate installation of the door, the detection performance is reliable, the detection principle is relatively simple, and it is easy to implement.

[0046] Reference below Figure 1-Figure 8 A hinge coaxiality detection device 100 according to an embodiment of the present invention is described.

[0047] Combination Figure 1-Figure 3 The hinge coaxiality detection device 100 of this embodiment can be used to detect the coaxiality of a vehicle body hinge 201, wherein the vehicle body hinge 201 is installed on the vehicle body 200, and there are two vehicle body hinges 201. For example, two vehicle body hinges 201 are installed at the installation position of the door 300 of the vehicle body 200, and the two vehicle body hinges 201 are arranged vertically opposite to each other. Each vehicle body hinge 201 is provided with a hinge hole. Accordingly, two hinge shafts 301 can be provided on the door 300, and the two hinge shafts 301 are respectively assembled with the two vehicle body hinges 201 to realize the assembly of the door 300 and the vehicle body 200.

[0048] Combination Figure 1 and Figure 2 The hinge coaxiality detection device 100 includes: a housing 1 and a laser emitting element 2. The housing 1 may be cylindrical or annular, and the housing 1 is fixed to one of the two vehicle body hinges 201. The laser emitting element 2 is disposed on the housing 1, and the laser emitting element 2 may be used to emit a laser beam 21, and the laser beam 21 is coaxial with the hinge hole of the vehicle body hinge 201 where the housing 1 is located, and the laser beam 21 is suitable for passing through the hinge hole of the vehicle body hinge 201 where the housing 1 is located, and emitting to the hinge hole of the other vehicle body hinge 201.

[0049] For example Figure 3 As shown, the two vehicle body hinges 201 are respectively a vehicle body upper hinge 201a and a vehicle body lower hinge 201b, and the housing 1 can be installed on the vehicle body upper hinge 201a, or the housing 1 can be installed on the vehicle body lower hinge 201b. Among them, when the shell 1 is fixed to the hinge 201a on the body, the laser beam 21 emitted by the laser emitting element 2 is coaxial with the hinge hole of the hinge 201a on the body, and passes through the hinge hole of the hinge 201a on the body to shoot to the hinge hole of the lower hinge 201b of the body. By observing whether the laser beam 21 passes through the hinge hole of the lower hinge 201b of the body, it is detected whether the hinge 201a on the body and the lower hinge 201b of the body are coaxial. Among them, when the laser beam 21 passes through the hinge hole of the lower hinge 201b of the body and the shape of the laser beam 21 does not change, it can be judged that the coaxiality of the hinge 201a on the body and the lower hinge 201b of the body is good; when the laser beam 21 passes through the hinge hole of the hinge 201a on the body and the shape of the laser beam 21 changes, it can be judged that there is a coaxiality deviation between the hinge 201a on the body and the lower hinge 201b of the body.

[0050] Alternatively, when the housing 1 is fixed to the lower hinge 201b of the vehicle body, the laser beam 21 emitted by the laser emitting element 2 is coaxial with the hinge hole of the lower hinge 201b of the vehicle body, and passes through the hinge hole of the lower hinge 201b of the vehicle body to be emitted to the hinge hole of the lower hinge 201b of the vehicle body. By observing whether the laser beam 21 passes through the hinge hole of the upper hinge 201a of the vehicle body, it is detected whether the upper hinge 201a and the lower hinge 201b of the vehicle body are coaxial. When the laser beam 21 passes through the hinge hole of the upper hinge 201a of the vehicle body and the shape of the laser beam 21 does not change, it can be determined that the coaxiality of the upper hinge 201a and the lower hinge 201b of the vehicle body is good; when the laser beam 21 passes through the hinge hole of the upper hinge 201a of the vehicle body and the shape of the laser beam 21 changes, it can be determined that there is a coaxiality deviation between the upper hinge 201a and the lower hinge 201b of the vehicle body.

[0051] Optionally, the shell 1 can be cylindrical or annular, so that when the hinge coaxiality detection device 100 is installed on the body hinge 201a or the body hinge 201b, the shell 1 can remain coaxial with the body hinge 201a or the body hinge 201b. The laser emitting element 2 can be arranged on the inner side of the shell 1. In this way, the coaxiality of the laser beam 21 emitted by the laser emitting element 2 and the hinge hole of the body hinge 201 can be ensured to be good.

[0052] According to the hinge coaxiality detection device 100 of the embodiment of the utility model, the laser beam 21 is emitted by the laser emitting element 2. When the laser beam 21 is ensured to be coaxial with the hinge hole of one of the body hinges 201, the laser beam 21 is emitted to the hinge hole of the other body hinge 201, thereby detecting the coaxiality of the two body hinges 201 according to whether the laser beam 21 can pass through the hinge holes of the two body hinges 201 at the same time, thereby providing an operating basis for the operator to adjust the body hinge 201, so as to facilitate the subsequent rapid and accurate installation of the door 300, and solve the problem of the lack of hinge coaxiality detection affecting the production rhythm, and the detection performance is reliable, the detection principle is relatively simple and convenient, the development cost is low, and the operation is flexible and light. In addition, compared with the solution of using a detection pin rod to detect the hinge coaxiality in the related art, it can save the inconvenience of manual operation, improve the detection efficiency, and also avoid the deformation of the detection pin rod affecting the detection accuracy.

[0053] The following description is based on an example in which the housing 1 is fixed to the hinge 201a on the vehicle body, and the laser beam 21 emitted by the laser emitting element 2 is coaxial with the hinge hole of the hinge 201a on the vehicle body and is emitted to the hinge hole of the hinge 201b under the vehicle body.

[0054] In some embodiments, the laser emitting element 2 is configured to emit a laser beam 21 with a variety of light characteristics, including at least one of the diameter of the laser beam 21, the line type of the laser beam 21, and the color of the laser beam 21. That is, the laser emitting element 2 of this embodiment can emit laser beams 21 of different diameters, line types, and colors according to actual needs. For example, the line type can be a concentric ring type, a cross anchor type, a star shape, or a custom shape, the color can be a highly recognizable color such as red, green, and yellow, and the diameter can be the sum of the design standard value of the hinge hole diameter and the allowable deviation value.

[0055] Of course, the present invention is not limited to this, and the light characteristics can also be other characteristics. In this way, the application scope of the hinge coaxiality detection device 100 of this embodiment can be improved, and it is compatible with hinge coaxiality detection requirements under more vehicle models and more detection conditions, and has better practicality.

[0056] In some embodiments, in combination Figure 7 and Figure 8 The shell 1 may be provided with a configuration port 11. For example, the configuration port 11 may be a USB interface or other types of data interfaces. The configuration port 11 may be communicatively connected with the laser emitting element 2. The configuration port 11 is used to configure the light characteristics of the laser beam 21.

[0057] That is to say, the operator can write the light characteristics of the laser beam 21 to the hinge coaxiality detection device 100 through the configuration port 11, so that the laser beam 21 with the corresponding light characteristics is emitted from the laser component. In this way, the laser beam 21 is customizable and replaceable, and the hinge coaxiality detection device 100 is configured with laser beams 21 with different light characteristics according to different vehicle models, so that the same set of hinge coaxiality detection devices 100 can be applied to the hinge coaxiality detection needs of various vehicle models, expanding the scope of use. Compared with the solution of developing more than two sets of detection pins (for detecting the maximum and minimum passing diameters) for each vehicle model in the related art, it can greatly reduce the detection cost and the detection accuracy is easier to ensure.

[0058] In some embodiments, the configuration port 11 is used to configure the first laser beam 21a and the second laser beam 21b for the laser emitting element 2 in a single configuration operation, the first laser beam 21a has a first diameter, and the first diameter is the upper limit value of the aperture of the hinge hole, the second laser beam 21b has a second diameter, and the second diameter is the lower limit value of the aperture of the hinge hole, and the hinge coaxiality detection device 100 detects the coaxiality of the vehicle body hinge 201 through the first laser beam 21a and the second laser beam 21b respectively.

[0059] That is to say, when the hinge coaxiality detection device 100 of the present embodiment is used to detect the coaxiality of the vehicle body hinge 201, the upper limit value of the aperture (i.e., the sum of the standard aperture and the upper deviation of the aperture) and the lower limit value of the aperture (i.e., the sum of the standard aperture and the lower deviation (negative number) of the aperture) corresponding to the design value of the hinge hole of the vehicle body hinge 201 corresponding to the vehicle model can be input through the configuration port 11. The upper limit value of the aperture is also the diameter of the first laser beam 21a, and the lower limit value of the aperture is the diameter of the second laser beam 21b. Then, the first laser beam 21a and the second laser beam 21b are used to detect the coaxiality of the vehicle body hinge 201. The first laser beam 21a and the second laser beam 21b emit laser beams 21 to another vehicle body hinge 201 that is not provided with the hinge coaxiality detection device 100. When any one of the first laser beam 21a and the second laser beam 21b completely passes through the hinge hole of the vehicle body hinge 201, it can be determined that the coaxiality of the two vehicle body hinges 201 is good, and when any one of the first laser beam 21a and the second laser beam 21b fails to completely pass through the hinge hole of the vehicle body hinge 201, it can be determined that the coaxiality of the two vehicle body hinges 201 is unqualified and needs to be adjusted. In this way, the accuracy of the detection result is improved.

[0060] In some embodiments, in combination Figure 7 and Figure 8 A switch button 12 may be provided on the housing 1. The switch button 12 is electrically connected to the laser emitting element 2. The switch button 12 is configured to control the laser emitting element 2 to switch between the first laser beam 21a and the second laser beam 21b when triggered. For example, when using the hinge coaxiality detection device 100 of this embodiment to detect the coaxiality of the vehicle body hinge 201, the laser emitting component 2 can be started first, and the laser emitting component 2 emits a first laser beam 21a to the lower hinge 201b of the vehicle body to observe whether the first laser beam 21a can pass through the hinge hole of the lower hinge 201b of the vehicle body, and then trigger the switching button 12 to make the laser emitting component 2 emit a second laser beam 21b to the lower hinge 201b of the vehicle body to observe whether the second laser beam 21b can pass through the hinge hole of the lower hinge 201b of the vehicle body. When any one of the first laser beam 21a and the second laser beam 21b passes through the hinge hole of the lower hinge 201b of the vehicle body, or both can pass through the hinge holes of the lower hinge 201b of the vehicle body, it can be judged that the coaxiality of the vehicle body hinge 201a and the vehicle body hinge 201a is within the allowable deviation range, and the detection result is qualified.

[0061] In this way, by setting the switch button 12, the laser beam 21 emitted by the laser emitting element 2 can be flexibly switched to respectively use the first laser beam 21a and the second laser beam 21b to perform coaxiality detection, thereby improving the accuracy of the detection result.

[0062] Optionally, the switch button 12 is a physical button; or, the switch button 12 can also be a virtual button set on the display screen, and the display screen can be used to display the light characteristic information of the current laser beam 21 and the light characteristic information of the switchable laser beam 21, etc., and of course can also be used to display detection results, etc.

[0063] In addition, the switch button 12 can also be configured to switch laser beams 21 of multiple colors and / or multiple line shapes, so as to further enrich the functions of the hinge coaxiality detection device 100 and improve its flexibility and convenience in use.

[0064] In some embodiments, the shell 1 can be stacked on the side of one of the body hinges 201 facing away from the other body hinge 201. For example, when the hinge coaxiality detection device 100 is arranged on the body hinge 201a, the shell 1 is arranged on the upper side of the body hinge 201a to ensure that the laser beam 21 is coaxial with the hinge hole of the body hinge 201a and accurately passes through the hinge hole of the body hinge 201a to shoot to the hinge hole of the lower hinge 201b of the body; when the hinge coaxiality detection device 100 is arranged on the body hinge 201b, the shell 1 is arranged on the lower side of the body hinge 201b to ensure that the laser beam 21 is coaxial with the hinge hole of the body hinge 201b and accurately passes through the hinge hole of the body hinge 201b to shoot to the hinge hole of the body hinge 201a.

[0065] refer to Figure 6 The hinge coaxiality detection device 100 may further include a fixing member 3. Specifically, the fixing member 3 is disposed on a side of the housing 1 facing the vehicle body hinge 201, and the fixing member 3 is used to fix the housing 1 to the vehicle body hinge 201.

[0066] For example, the fixing part 3 can be a snap-fit ​​part to facilitate snap-fitting with the vehicle body hinge 201; or, the fixing part 3 can be a plug-in part to facilitate plug-fitting with the vehicle body hinge 201. Of course, the present invention is not limited to this. The matching method between the fixing part 3 and the vehicle body hinge 201, the structure and quantity of the fixing part 3 can all be reasonably set according to actual needs.

[0067] By providing the fixing member 3 and fixing the housing 1 to the vehicle body hinge 201 , a stable support can be provided for the laser emitting member 2 , thereby ensuring the stability of its position during the detection process, thereby improving the accuracy of the detection result.

[0068] In some embodiments, the fixing member 3 is a magnetic member, and the fixing member 3 is magnetically matched with the body hinge 201. In this way, the matching method of the fixing member 3 and the body hinge 201 is relatively simple, low in cost, and easy to implement. Optionally, the fixing member 3 can be arranged on the surface of the shell 1, or can be coated inside the shell 1.

[0069] In some embodiments, a mounting groove is provided on one side of the shell 1 facing the body hinge 201, and the fixing member 3 is embedded in the mounting groove. In this way, the mounting method of the fixing member 3 on the shell 1 and the structure of the shell 1 itself are relatively simple and easy to assemble.

[0070] Optionally, there may be multiple fixing members 3, and accordingly, the number of mounting grooves corresponds to that of the fixing members 3, and the multiple mounting grooves may be arranged at intervals along the circumference of the shell 1 to ensure the connection stability between the shell 1 and the body hinge 201 in the circumferential direction.

[0071] In some embodiments, in combination Figure 4 , Figure 7 and Figure 8 The hinge coaxiality detection device 100 may further include: a coaxiality positioning frame 4. Specifically, the coaxiality positioning frame 4 is arranged on the side of the housing 1 facing the vehicle body hinge 201, and the projection of the coaxiality positioning frame 4 in the reference plane is within the projection of the hinge hole in the reference plane, and the reference plane is perpendicular to the axis of the hinge hole.

[0072] For example, the coaxiality positioning frame 4 is located on the lower side of the shell 1. At this time, the coaxiality positioning frame 4 can be in the hinge hole to ensure that the laser beam 21 emitted by the laser emitting element 2 is coaxial with the hinge hole. In this way, after the laser beam 21 passes through the hinge hole of the hinge 201a on the vehicle body, it can be emitted to the hinge hole of the lower hinge 201b of the vehicle body to detect the coaxiality of the lower hinge 201b of the vehicle body and the hinge 201a on the vehicle body.

[0073] In some embodiments, in combination Figure 4 and Figure 6 The coaxiality positioning frame 4 includes a plurality of positioning feet 41, and the outer sides of the projections of the plurality of positioning feet 41 in the reference plane are on the same reference circle, and the diameter of the reference circle corresponds to the inner diameter of the hinge hole. For example, the outer side surfaces of the plurality of positioning feet 41 are on the same conical surface or cylindrical surface, and the maximum diameter of the conical surface or cylindrical surface corresponds to the inner diameter of the hinge hole. In this way, when the coaxiality positioning frame 4 is extended into the hinge hole, it can prevent the hinge coaxiality detection device 100 from being displaced radially relative to the vehicle body hinge 201, which causes the laser emitting component 2 and the hinge hole of the vehicle body hinge 201 to be not in a coaxial state, which is not conducive to improving the reliability of the detection result.

[0074] In some embodiments, in combination Figure 4 and Figure 6, along the axial direction of the shell 1 and in the direction away from the shell 1, the diameter of the coaxial positioning frame 4 gradually decreases. In other words, along the axial direction of the shell 1 and in the direction away from the shell 1, the diameter of the reference circle determined by the outer side of the projection of the plurality of positioning feet 41 in the reference plane gradually decreases. For example, the outer side surfaces of the plurality of positioning feet 41 are all on the same conical surface. In this way, when the hinge coaxiality detection device 100 is inserted into the hinge hole, the coaxiality positioning frame 4 can play a guiding role, ensuring that the hinge coaxiality detection device 100 is efficiently and accurately installed on the body hinge 201, and at the same time ensuring that the laser beam 21 emitted by the laser emitting element 2 and the hinge hole of the body hinge 201 are in good coaxiality.

[0075] In some embodiments, a battery compartment 13 is further provided on the shell 1, and the battery compartment 13 can be arranged on the side of the shell 1 facing away from the body hinge 201. The hinge coaxiality detection device 100 also includes a power supply battery 5, and the power supply battery 5 can be a button battery, or other types of batteries. The power supply battery 5 is arranged in the battery compartment 13. The power supply battery 5 can provide electrical energy for other components of the hinge coaxiality detection device 100, such as the laser emitting component 2, to facilitate detection work.

[0076] Optionally, the energy supply battery 5 can be fixed in the battery compartment 13, and the shell 1 can be provided with a charging interface to charge the energy supply battery 5, thereby realizing battery reuse and reducing usage costs; or, the energy supply battery 5 can be detachably arranged in the battery compartment 13 and can be easily replaced.
