[0046] The automotive industry is developing rapidly. To meet the market's increasingly diverse demands for appearance and performance, vehicle upgrades and development are accelerating, and consumers are demanding increasingly sophisticated vehicle appearance. The assembly accuracy of the front hood lock 300 directly affects the gap between the front hood and the front end frame 200 of the vehicle body. To ensure the gap between the front hood and the front end frame 200 meets regulatory requirements, the front hood lock 300 must be manually and repeatedly adjusted during assembly. However, this manual adjustment process is time-consuming, inefficient, and impacts the production line's tact time.

[0047] In view of this, the embodiment of the present application provides an assembly positioning tool 100 for the automobile front hood lock 300, which can improve the assembly accuracy of the automobile front hood lock 300, ensure that the gap between the front hood and the front end frame 200 of the vehicle body meets the specifications, reduce the cumulative tolerance of the component size chain, ensure the appearance matching accuracy of the components, and do not require manual repeated adjustment of the automobile front hood lock 300, thereby shortening the assembly time, improving production efficiency, and avoiding affecting the rhythm of the workshop production line.

[0048] It should be noted that the vehicles or cars mentioned in this application may refer to large cars, small cars, special-purpose cars, etc. For example, according to the type of car, the vehicles or cars in this application may be sedans, off-road vehicles, multi-purpose vehicles (MPVs), or other types of cars. Generally, a vehicle is provided with a front end frame 200, fenders, a front hood, and a front hood lock 300, etc. Figure 5 As shown, the lock catch 400 cooperates with the automobile front hood lock 300 to lock or unlock the vehicle front end frame 200 and the vehicle front hood.

[0049] Reference below Figures 1-6 The following describes an assembly and positioning tool 100 for an automobile front hood lock 300 according to an embodiment of the present invention.

[0050] Specifically, refer to Figure 1 As shown, the assembly and positioning tool 100 of this embodiment can be used to assemble a front hood lock 300 of an automobile. The front end frame 200 of the vehicle body has a mounting portion, a positioning portion, and a limiting portion. The mounting portion of the front end frame 200 is used to mount the front hood lock 300 of the automobile. That is, the front hood lock 300 of the automobile is mounted at the mounting portion. The assembly and positioning tool 100 of this embodiment of the present application can be used to assemble the front hood lock 300 of the automobile to the front end frame 200 of the vehicle body. The assembly and positioning tool 100 can include: a tool body 4, a first assembly component 1, a second assembly component 2, and a third assembly component 3.

[0051] Specifically, the tool body 4 is the basic structure of the assembly and positioning tool 100, and other components are installed on the tool body 4. The first assembly component 1 is provided on the tool body 4. The first assembly component 1 is suitable for clamping the automobile front hood lock 300 in the Y direction. It can be understood that the function of the first assembly component 1 is to clamp the automobile front hood lock 300 in the Y direction (such as Figure 1 Clamp the car front hood lock 300 in the Z direction (as shown in the left and right directions) to ensure that the car front hood lock 300 is in the Z direction (as shown in the left and right directions) Figure 1 The position stability and accuracy in the up and down directions (as shown) help prevent the automobile front hood lock 300 from being displaced in the Z direction during the assembly process.

[0052] The second assembly component 2 is provided on the tooling body 4. The second assembly component 2 is configured to cooperate with the positioning portion to limit the relative position of the automobile front hood lock 300 and the mounting portion in the X direction. It can be understood that the second assembly component 2 cooperates with the positioning portion on the front end frame 200 of the vehicle body to ensure that the automobile front hood lock 300 and the mounting portion are in the X direction (such as Figure 1 The relative position in the front-to-back direction (as shown) is accurate, thereby avoiding the deviation of the automobile front hood lock 300 in the front-to-back direction.

[0053] The third assembly component 3 is provided on the tooling body 4 and is spaced apart from the second assembly component 2 in the Z direction. The third assembly component 3 is configured to cooperate with the limiting portion to limit the relative position of the automobile front hood lock 300 and the mounting portion in the Z direction. It can be understood that the third assembly component 3 cooperates with the limiting portion on the front end frame 200 of the vehicle body to limit the relative position of the automobile front hood lock 300 and the mounting portion in the Z direction (such as Figure 1 The relative position in the up and down direction shown in FIG. 3 ) ensures that the automobile front hood lock 300 does not deviate in the up and down direction during installation and maintains the correct height position.

[0054] refer to Figure 1 and Figure 6 As shown, the process flow of the assembly and positioning tool 100 of the embodiment of the present application is as follows:

[0055] 1. Place the car front hood lock 300 at the mounting position of the front end frame 200 of the vehicle body;

[0056] 2. Use fasteners to pre-install the car front hood lock 300 on the mounting portion;

[0057] 3. Using the assembly positioning tool 100, the first assembly component 1 clamps the automobile front hood lock 300;

[0058] 4. Adjust the second assembly component 2 to match the positioning portion;

[0059] 5. Adjust the third assembly component 3 to match the limiting portion;

[0060] 6. After the assembly positioning tool 100 is locked and positioned, use a tightening tool to adjust the fasteners, unlock the first assembly component 1, the second assembly component 2 and the third assembly component 3, remove the assembly positioning tool 100, and complete the assembly.

[0061] Here, in order to facilitate assembly, it can be assembled in conjunction with an assembly device for the automobile front hood lock 300 , and the assembly device can be an assembly robot, or an electric / pneumatic bolt gun or other equipment.

[0062] In general, it can be understood that the second assembly component 2 cooperates with the positioning portion of the front end frame 200 of the vehicle body, and the third assembly component 3 cooperates with the limiting portion of the front end frame 200 of the vehicle body, and together they define the target position of the automobile front hood lock 300 when assembled on the mounting portion, so that the automobile front hood lock 300 and the mounting portion have a fixed relative positional relationship.

[0063] According to the assembly positioning tool 100 of the automobile front hood lock 300 of the embodiment of the present application, precise positioning in the X, Y, and Z directions is achieved by assembling components and cooperating with the front end frame 200 of the vehicle body, fully considering the multi-dimensional positioning requirements, improving the assembly accuracy of the automobile front hood lock 300, ensuring that the gap between the vehicle body front hood and the front end frame 200 of the vehicle body meets the specifications, reducing the cumulative tolerance of the component size chain, ensuring the appearance matching accuracy of the components, and eliminating the need for manual repeated adjustment of the automobile front hood lock 300, thereby shortening the assembly time, improving production efficiency, and enhancing product quality.

[0064] In addition, the assembly and positioning tool 100 of the automobile front hood lock 300 according to the embodiment of the present application can also be used in combination with automated equipment, thereby further improving the automation level and efficiency of the production line.

[0065] In addition, the fasteners mentioned above include but are not limited to bolts, screws, rivets, pins, etc.

[0066] In some embodiments of the present application, Figure 1 and Figure 2 As shown, the limiting portion is formed as a limiting hole 201. The third assembly component 3 includes a limiting member 31. The limiting member 31 is adapted to be inserted into the limiting hole 201. The limiting member 31 cooperates with the limiting hole 201 to fix the position of the automobile front hood lock 300 in the XY plane. It is understood that the limiting hole 201 is a pre-set hole in the front frame 200 of the vehicle body, and is used to cooperate with the limiting member 31 on the assembly positioning tool 100 to ensure the precise positioning of the automobile front hood lock 300 in the XY plane. The limiting member 31, as part of the third assembly component 3, is configured to be inserted into the limiting hole 201. When the limiting member 31 is inserted into the limiting hole 201, it can fix the automobile front hood lock 300 in the XY plane and prevent the automobile front hood lock 300 from displacement.

[0067] In short, the limiting member 31 in the third assembly component 3 cooperates with the limiting hole 201 on the front end frame 200 of the vehicle body, which not only limits the position of the automobile front hood lock 300 in the Z direction, but also further fixes the position of the automobile front hood lock 300 in the XY plane, and provides additional stability, ensuring that the automobile front hood lock 300 can be accurately and stably installed on the front end frame 200 of the vehicle body, ensuring the assembly quality of the automobile front hood lock 300, and improving the assembly efficiency.

[0068] Optionally, an outer peripheral wall of the limiting member 31 is formed with an external thread, and an inner peripheral wall of the limiting hole 201 is formed with an internal thread, and the limiting member 31 and the limiting hole 201 are fixedly connected by the internal and external threads.

[0069] Furthermore, if Figure 2 As shown, the limiting member 31 extends along the Z direction, the front end frame 200 of the vehicle body is formed with a convex plate 202 extending along the X direction, and the limiting hole 201 is formed on the convex plate 202 and passes through the convex plate 202 in the Z direction. It can be understood that the convex plate 202 extends along the X direction (such as Figure 2 The convex plate 202 provides a fixed reference surface for constructing the limiting hole 201. The limiting hole 201 is formed on the convex plate 202 and extends in the Z direction (as shown in the front and rear directions). Figure 2 The limiting member 31 extends along the Z direction and is suitable for being inserted into the limiting hole 201 to fix the position of the car front hood lock 300 on the XY plane and limit the movement of the car front hood lock 300 in the Z direction.

[0070] In short, after the position-limiting member 31 is inserted into the position-limiting hole 201, it not only fixes the position of the front hood lock 300 in the Z direction, but also ensures the precise position of the front hood lock 300 in the XY plane through the constraint of the position-limiting hole 201. In this way, through multi-dimensional positioning and fixation, the high precision and stability of the front hood lock 300 during installation are ensured. The raised plate 202 and the position-limiting hole 201 further enhance the reliability of positioning, improving the quality and efficiency of the overall assembly.

[0071] In some embodiments, the limiting member 31 is formed as a limiting column, which extends along the Z direction, and the size and shape of the limiting column are adapted to the size and shape of the limiting hole 201 .

[0072] Furthermore, the plurality of limiting holes 201 are arranged on both sides of the mounting portion in the Y direction, and the plurality of limiting members 31 are provided in a one-to-one correspondence with the plurality of limiting holes 201. It is understood that the limiting holes 201 are arranged on both sides of the mounting portion in the Y direction, and each limiting hole 201 corresponds to a limiting member 31. The limiting members 31 are inserted into the corresponding limiting holes 201 to fix the position of the automobile front hood lock 300 in the XY plane and limit the displacement of the automobile front hood lock 300 in the Z direction.

[0073] In short, multiple limiting holes 201 are arranged on both sides of the mounting portion in the Y direction, and each limiting hole 201 corresponds to a limiting member 31, which further enhances the positioning accuracy and stability of the automobile front hood lock 300 in the XY plane. Through multi-point fixation and multi-dimensional positioning, the high precision of the automobile front hood lock 300 during the installation process is ensured. The cooperation of multiple limiting members 31 and multiple limiting holes 201 further enhances the reliability of positioning and improves the quality and efficiency of the overall assembly.

[0074] Reference Figure 1 As shown in FIG. 1 , a specific embodiment of the present application includes two limiting holes 201 and two limiting members 31, with the two limiting members 31 arranged in a one-to-one correspondence with the two limiting holes 201. A protruding plate 202 is arranged on both sides of the mounting portion in the Y direction, and each protruding plate 202 is formed with a limiting hole 201. This ensures positioning while also ensuring balance and accuracy.

[0075] In some other feasible embodiments, the number of the limiting holes 201 is but not limited to two, and the number of the limiting members 31 is but not limited to two.

[0076] In other embodiments of the present application, the limiting hole 201 can be directly formed on the front frame 200 of the vehicle body without providing the protruding plate 202 , and the limiting member 31 is adapted to the shape and size of the limiting hole 201 .

[0077] In some embodiments of the present application, Figure 2 As shown, the third assembly component 3 also includes: a first connecting member 32, the first connecting member 32 is provided on the tool body 4, and a limiting member 31 is provided through the first connecting member 32 and is located at the end of the first connecting member 32 away from the tool body 4. The limiting member 31 can move in the Z direction relative to the first connecting member 32. It can be understood that the first connecting member 32 provides an installation position for the limiting member 31, further enhancing the reliability and flexibility of positioning, and improving the quality and efficiency of the overall assembly. A first connecting hole is formed at the end of the first connecting member 32 away from the tool body 4. The first connecting hole passes through the end of the first connecting member 32 away from the tool body 4 along the Z direction, and the limiting member 31 can move in the first connecting hole along the axial direction of the first connecting hole.

[0078] As shown in the figure, a specific embodiment of the present application is shown, wherein the first connecting member 32 includes two, one end of the two first connecting members 32 (such as Figure 2 The front ends of the first connecting members 32 shown in FIG. 3 are connected to the tool body 4, and the other ends of the two first connecting members 32 (as shown in FIG. Figure 2 The rear end of the first connecting member 32 shown extends in a direction away from the tooling body 4, and the other ends of the two first connecting members 32 are each formed with a first connecting hole, and the two limiting members 31 are respectively inserted into the holes of the two first connecting members 32.

[0079] Furthermore, the first connecting member 32 and the tool body 4 can be connected by welding, thereby ensuring the connection reliability between the first connecting member 32 and the tool body 4 .

[0080] In order to expand the application range of the assembly and positioning tool 100, in some feasible embodiments, the first connecting member 32 and the tool body 4 are detachably connected. Specifically, the first connecting member 32 and the tool body 4 can be connected by fasteners. In this way, when assembling different car models, it is only necessary to replace the first connecting member 32 suitable for assembling the current car model. While reducing the production cost of the assembly and positioning tool 100, the assembly accuracy of the automobile front hood lock 300 is guaranteed.

[0081] In some embodiments of the present application, Figure 1 As shown, the positioning portion is formed as a positioning hole 203, which extends along the X-direction. The second assembly component 2 includes a positioning member 21, which extends along the X-direction and is adapted to be inserted into the positioning hole 203. The positioning member 21 cooperates with the positioning hole 203 to secure the position of the front hood lock 300 in the YZ plane. It will be understood that the positioning hole 203 is a pre-set hole in the front frame 200 of the vehicle body, and is used to cooperate with the positioning member 21 on the assembly positioning tool 100 to ensure the precise positioning of the front hood lock 300 in the YZ plane. The positioning member 21, as part of the second assembly component 2, is configured to be inserted into the positioning hole 203. Once inserted into the positioning hole 203, the positioning member 21 secures the front hood lock 300 in the YZ plane, preventing displacement of the front hood lock 300.

[0082] In short, the positioning member 21 in the second assembly component 2 cooperates with the positioning hole 203 on the front end frame 200 of the vehicle body, which not only limits the position of the automobile front hood lock 300 in the X direction, but also further fixes the position of the automobile front hood lock 300 in the YZ plane and provides additional stability, ensuring that the automobile front hood lock 300 can be accurately and stably installed on the front end frame 200 of the vehicle body, ensuring the assembly quality of the automobile front hood lock 300 and improving assembly efficiency.

[0083] Optionally, an outer peripheral wall of the positioning member 21 is formed with an external thread, and an inner peripheral wall of the positioning hole 203 is formed with an internal thread, and the positioning member 21 and the positioning hole 203 are fixedly connected by the internal and external threads.

[0084] Furthermore, the positioning member 21 extends in the X-direction, and the positioning hole 203 also extends in the X-direction. When the positioning member 21 is inserted into the positioning hole 203, it not only fixes the position of the front hood lock 300 in the X-direction, but also ensures the precise position of the front hood lock 300 in the YZ plane through the constraint of the positioning hole 203. In this way, the multi-dimensional positioning and fixation ensures high precision and stability of the front hood lock 300 during installation, improving the quality and efficiency of the overall assembly.

[0085] In some embodiments, the positioning member 21 is formed as a positioning column, which extends along the X direction, and the size and shape of the positioning column are adapted to the size and shape of the positioning hole 203 .

[0086] Furthermore, the positioning holes 203 include a plurality of positioning holes 203, which are arranged at intervals, and the positioning members 21 include a plurality of positioning members 21, which are provided in a one-to-one correspondence with the positioning holes 203. It is understood that, in order to ensure accurate positioning, the plurality of positioning holes 203 are provided, and the plurality of positioning holes 203 are arranged at intervals in the YZ plane. Each positioning hole 203 corresponds to a positioning member 21, and the positioning member 21 is inserted into the corresponding positioning hole 203 to fix the position of the automobile front hood lock 300 in the YZ plane and limit the displacement of the automobile front hood lock 300 in the X direction.

[0087] In short, multiple positioning holes 203 are arranged at intervals in the YZ plane, and each positioning hole 203 corresponds to a positioning member 21, which further enhances the positioning accuracy and stability of the automobile front hood lock 300 in the YZ plane. Through multi-point fixation and multi-dimensional positioning, the high precision of the automobile front hood lock 300 during installation is ensured. The cooperation of multiple positioning members 21 and multiple positioning holes 203 further enhances the reliability of positioning and improves the quality and efficiency of the overall assembly.

[0088] Reference Figure 1 As shown in FIG. 1 , which is a specific embodiment of the present application, the positioning holes 203 include two, the positioning members 21 include two, the two positioning members 21 are arranged in a one-to-one correspondence with the two positioning holes 203, and the two positioning holes 203 are aligned with the two limiting holes 201 in the Z direction (such as Figure 1 The two positioning holes 203 are spaced apart in the Y direction (as shown in the vertical direction), and the distance between the two positioning holes 203 is Figure 1 In this way, the positioning is achieved while ensuring balance and accuracy.

[0089] In some other feasible embodiments, the number of the positioning holes 203 is but not limited to two, and the number of the positioning members 21 is but not limited to two.

[0090] In some embodiments of the present application, Figure 1 and Figure 2 As shown, the second assembly component 2 also includes a second connector 22, which is disposed on the tool body 4. The positioning member 21 is disposed through the second connector 22 and is located at the end of the second connector 22 away from the tool body 4. The positioning member 21 is movable in the X direction relative to the second connector 22. It will be understood that the second connector 22 provides a mounting location for the positioning member 21, further enhancing the reliability and flexibility of positioning, and improving the quality and efficiency of the overall assembly. A second connecting hole is formed at the end of the second connector 22 away from the tool body 4. The second connecting hole extends along the X direction through the end of the second connector 22 away from the tool body 4, and the positioning member 21 is movable in the axial direction of the second connecting hole within the second connecting hole.

[0091] As shown in the figure, a specific embodiment of the present application is shown, wherein the second connecting member 22 includes two, one end of the two second connecting members 22 (such as Figure 1 The upper ends of the second connecting members 22 shown in FIG. 2 are connected to the tool body 4, and the other ends of the two second connecting members 22 (as shown in FIG. Figure 1 The lower end of the second connecting member 22 shown in the figure extends in a direction away from the tooling body 4, and the other ends of the two second connecting members 22 are each formed with a second connecting hole, and the two positioning members 21 are respectively inserted into the holes of the two second connecting members 22.

[0092] Furthermore, the second connecting member 22 and the tooling body 4 can be connected by welding, thereby ensuring the connection reliability between the second connecting member 22 and the tooling body 4 .

[0093] In order to expand the application range of the assembly and positioning tool 100, in some feasible embodiments, the second connecting member 22 and the tool body 4 are detachably connected. Specifically, the second connecting member 22 and the tool body 4 can be connected by fasteners. In this way, when assembling different car models, it is only necessary to replace the second connecting member 22 suitable for assembling the current car model. While reducing the production cost of the assembly and positioning tool 100, the assembly accuracy of the automobile front hood lock 300 is guaranteed.

[0094] In some embodiments of the present application, the first assembly component 1 includes a clamping member 11 and a third connecting member 12. The third connecting member 12 is provided on the tool body 4. The clamping member 11 is provided on the third connecting member 12 and is located at an end of the third connecting member 12 away from the tool body 4. The clamping member 11 is movable in the Y direction relative to the third connecting member 12. It can be understood that the clamping member 11 clamps the automobile front hood lock 300 in the Y direction to ensure the stability of the automobile front hood lock 300 in the Y direction. The mobility of the clamping member 11 in the Y direction, the mobility of the positioning member 21 in the X direction, and the mobility of the limiting member 31 in the Z direction provide fine-tuning capabilities to accommodate positioning holes 203 and limiting holes 201 of different sizes and tolerances, thereby increasing assembly flexibility.

[0095] Furthermore, the third connecting member 12 and the tooling body 4 can be connected by welding, thereby ensuring the connection reliability between the third connecting member 12 and the tooling body 4 .

[0096] In order to expand the application range of the assembly and positioning tool 100, in some feasible embodiments, the third connecting member 12 and the tool body 4 are detachably connected. Specifically, the third connecting member 12 and the tool body 4 can be connected by fasteners. In this way, when assembling different car models, it is only necessary to replace the third connecting member 12 suitable for assembling the current car model. While reducing the production cost of the assembly and positioning tool 100, the assembly accuracy of the automobile front hood lock 300 is guaranteed.

[0097] It should be noted that, in the embodiment of the present application, the specific forms of the first connecting member 32, the second connecting member 22 and the third connecting member 12 are not limited, and they can be adapted according to the assembly of different vehicle models.

[0098] Refer to the following Figures 1-6 The working principle of the assembly and positioning tool 100 of the automobile front hood lock 300 according to the embodiment of the present application is described as follows:

[0099] First, the first assembly component 1 plays the role of initial positioning;

[0100] Specifically, the clamping member 11 of the first assembly component 1 clamps the automobile front hood lock 300 in the Y direction, ensuring its vertical stability. The clamping member 11 is supported by the third connecting member 12 and can move in the Y direction to allow fine adjustment during clamping, ensuring the precise position of the automobile front hood lock 300 in the Y direction.

[0101] Next, the second assembly component 2 is used to position the automobile front hood lock 300 in the YZ plane;

[0102] Specifically, the multiple positioning members 21 of the second assembly component 2 are respectively inserted into the multiple positioning holes 203 on the front end frame 200 of the vehicle body to ensure the precise positioning of the automobile front hood lock 300 on the YZ plane. The positioning members 21 are supported by the second connecting member 22 and can move in the X direction so as to be fine-tuned when inserted into the positioning holes 203 to ensure the precise position of the automobile front hood lock 300 in the X direction. After each positioning member 21 is inserted into the corresponding positioning hole 203, the position of the automobile front hood lock 300 on the YZ plane is fixed to prevent it from moving in the Y and Z directions.

[0103] Then, the third assembly component 3 is used to position the automobile front hood lock 300 in the XY plane;

[0104] Specifically, the multiple limiting members 31 of the third assembly component 3 are respectively inserted into the multiple limiting holes 201 on the protruding plate 202. The limiting members 31 are supported by the first connecting member 32 and can move in the Z direction so that fine-tuning can be performed when inserted into the limiting holes 201 to ensure the precise position of the car front hood lock 300 in the Z direction. Since the limiting holes 201 are arranged on both sides of the mounting part in the Y direction, the insertion of the multiple limiting members 31 not only fixes the position of the car front hood lock 300 in the Z direction, but also provides multiple fixing points in the Y direction to ensure the precise position of the car front hood lock 300 on the XY plane.

[0105] It can be understood from another perspective that the first assembly component 1 clamps the automobile front hood lock 300 to constrain the displacement of the automobile front hood lock 300 in the X direction and the Y direction, the positioning member 21 of the second assembly component 2 cooperates with the positioning hole 203 of the front end frame 200 of the vehicle body to constrain the displacement of the automobile front hood lock 300 in the Y direction and the Z direction, and the limiting member 31 of the third assembly component 3 cooperates with the limiting hole 201 of the front end frame 200 of the vehicle body to constrain the displacement of the automobile front hood lock 300 in the X direction and the Y direction. Therefore, the assembly positioning tool 100 of the embodiment of the present application ensures that the automobile front hood lock 300 has two constraints in the X direction, the automobile front hood lock 300 has two constraints in the Y direction, and the automobile front hood lock 300 has two constraints in the Z direction at the same time.

[0106] In some embodiments of the present application, Figure 2 As shown, the clamping members 11 are arranged in pairs to define a clamping space, and the automobile front hood lock 300 is located in the clamping space. A bottom support member 6 is provided below the clamping space to support the automobile front hood lock 300, further improving the stability and accuracy of the clamping. In addition, the assembly positioning tool 100 also includes a gripping member 5, which is connected to the tool body 4 and is located on the side of the tool body 4 away from the front end frame 200 of the vehicle body. The provision of the gripping member 5 facilitates the operator or the assembly robot to grip or operate, thereby improving the convenience and efficiency of the operation.
