[0001] This application relates to the field of vehicle manufacturing technology, and in particular to a tooling for installing plastic nuts. Background Technology

[0002] In the automotive manufacturing industry, plastic nuts are widely used in parts such as car bodies, interiors, and engines. Due to their lightweight nature and excellent chemical resistance, they play a crucial role in the automotive manufacturing process.

[0003] With the increasing popularity of automobiles, their quality has steadily improved, leading to higher standards in quality control during manufacturing. A good car is inseparable from meticulous craftsmanship and strict requirements. Currently, plastic nuts are installed manually by pressing them with fingers. Due to the soft and elastic nature of plastic nuts, this method often results in improper installation, misalignment, or insufficient tightening, leading to reduced manufacturing precision of vehicle components. Furthermore, manual installation inevitably leads to finger fatigue and lack of concentration, further degrading the installation quality of plastic nuts, reducing production efficiency, and delaying production schedules.

[0004] Therefore, a tooling for installing plastic nuts needs to be designed to solve the above problems. Utility Model Content

[0005] In view of this, in order to overcome the defects of the prior art, this utility model provides a tooling for installing plastic nuts, which effectively solves the problems of improper installation, installation position deviation, inadequate tightening, reduced manufacturing precision and reduced production efficiency caused by manual pressing of plastic nuts with fingers.

[0006] According to the present invention, a tooling for installing plastic nuts includes a push rod, a nut mounting part, and a straightening part. The nut mounting part is disposed at the first end of the push rod, and the straightening part is sleeved on the first end of the push rod. The straightening part is movably connected to the push rod via an elastic component. The tooling can switch between a connected state and a used state. When the tooling is in the connected state, a plastic nut is mounted on the nut mounting part and abuts against the straightening part to straighten the plastic nut to be installed. When the tooling is in the used state, pushing the push rod causes the plastic nut mounted on the nut mounting part to separate from the straightening part.

[0007] Preferably, the nut mounting part includes a connecting rod, which is disposed on the end face of the first end of the push rod; when the plastic nut mounting fixture is in the connected state, the first part of the connecting rod is located inside the straightening part, and the second part of the connecting rod is located outside the straightening part.

[0008] Preferably, the end face of the first end of the straightening part is formed as an annular surface, the annular surface including an inner ring and an outer ring, the inner ring being closer to the nut mounting part relative to the outer ring; the inner ring being closer to the second end of the push rod relative to the outer ring.

[0009] Preferably, the push rod includes a first rod portion and a second rod portion connected to each other, the size of the first rod portion is smaller than the size of the second rod portion, the first rod portion is located inside the straightening portion, the straightening portion is sleeved on the second rod portion, and an installation space is formed between the inner wall of the straightening portion and the first rod portion.

[0010] Preferably, the elastic component includes an elastic element and a fixing element, the first rod portion has a moving hole, the straightening portion has a mounting hole, the fixing element passes through the mounting hole and the moving hole, and the elastic element is disposed in the mounting space.

[0011] Preferably, the elastic element is sleeved on the first rod portion, the first end of the elastic element is connected to the fixing element, and the second end of the elastic element is disposed on the end face where the second rod portion connects to the first rod portion.

[0012] Preferably, the second end of the push rod is formed as a third rod portion, and the size of the third rod portion is larger than the size of the second rod portion.

[0013] Preferably, the straightening part includes a first sleeve part and a second sleeve part connected to each other, the size of the first sleeve part corresponds to the size of the first rod part, and the size of the second sleeve part corresponds to the size of the second rod part; a first part of the first rod part passes through the first sleeve part, and a second part of the first rod part and the second rod part pass through the second sleeve part.

[0014] Preferably, the length of the second rod is greater than the length of the first rod.

[0015] Preferably, the movable hole is formed as an oblong hole.

[0016] According to the tooling for installing plastic nuts of this utility model, the cooperation of the push rod, the nut mounting part, and the straightening part enables quick and easy installation of plastic nuts. By installing the plastic nut onto the nut mounting part and abutting against the straightening part, the plastic nut can be ensured at the correct installation angle while receiving a certain degree of fixed support. In this step, the user only needs to align the connecting hole of the plastic nut with the nut mounting part, and the straightening part will assist in straightening the plastic nut. The connection is quick and convenient, and it avoids the installation misalignment of the plastic nut that occurs in the original connection method. When installing the plastic nut into the mounting hole on the vehicle component, pushing the push rod causes the nut mounting part to extend from the centering part, thereby allowing the plastic nut to be installed in the corresponding mounting position. During installation, the cooperation between the centering part and the push rod ensures that the plastic nut is installed and tightened in place, thus ensuring the manufacturing precision of the vehicle. In addition, since the entire installation process does not require manual tightening with fingers, it avoids finger fatigue and lack of concentration that can occur with manual installation. This allows users to effectively and continuously install plastic nuts, reducing the difficulty of the operation, ensuring the installation and assembly quality of plastic nuts, and improving production efficiency.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0032] According to the present invention, a tooling for installing plastic nuts is provided, such as... Figures 1 to 8 As shown, the plastic nut installation tool is used for installing plastic nut parts. The plastic nut installation tool can assist manual installation of plastic nut parts. The plastic nut installation tool includes a push rod 1, a nut installation part 2, and a straightening part 3.

[0033] In the following description, reference will be made to Figures 1 to 8 The detailed structure of the push rod 1, nut mounting part 2, and straightening part 3 of the tooling for installing the plastic nut is described in detail. Furthermore, it should be noted that the plastic nut mentioned below can be a commonly used plastic nut in the prior art. This type of plastic nut may have a connecting hole in its center, and the inner wall of the connecting hole may be provided with internal threads, or the connecting hole may be directly formed as a through hole. The connecting hole of the plastic nut can mate with the nut mounting part 2 to achieve connection. Additionally, for ease of description and understanding, in the following description, the connection of the plastic nut can be understood as the connection between the plastic nut and the tooling for installing the plastic nut, and the installation of the plastic nut can be understood as installing the plastic nut onto the corresponding mounting position of the vehicle component using the tooling for installing the plastic nut.

[0034] like Figure 1 and Figure 2As shown, in this embodiment, the push rod 1 can be understood as the main body of the tooling for installing the plastic nut. The user can use the push rod 1 to install the plastic nut into the corresponding mounting position of the vehicle component. The nut mounting part 2 is provided at the first end of the push rod 1 and is used for connecting the plastic nut. The straightening part 3 is sleeved on the first end of the push rod 1 and is movably connected to the push rod 1 through an elastic component. The straightening part 3 is used to straighten the plastic nut installed on the nut mounting part 2, so that the plastic nut maintains the correct installation angle for subsequent installation. Since the straightening part 3 is provided, the manpower required for installation can be reduced by the assistance of the straightening part 3. The straightening part 3 can be understood as being formed as a sleeve structure. The sleeve structure is sleeved on the push rod 1 and plays a straightening role when the plastic nut is connected to the nut mounting part 2. When the plastic nut is installed in the mounting position of the vehicle component (e.g., a mounting through hole), the straightening part 3 can assist in the installation. Since the centering part 3 and the push rod 1 can be slidably connected, during installation, the centering part 3 and the plastic nut are initially aligned with the installation position, and then the user pushes the push rod 1 to push the plastic nut into the installation position.

[0035] In this embodiment, the tooling for installing the plastic nut can switch between a connected state and a used state, such as... Figure 7 As shown, the tooling for installing the plastic nut is in the connected state, as... Figure 8 As shown, the tooling for installing the plastic nut is in use, which can be understood as the installation state of the plastic nut. The difference between these two states lies in the relative position between the push rod 1 and the centering part 3. This can also be understood as the user pushing the push rod 1, causing it to move upwards (here, "up" refers to...). Figure 7 and Figure 8 (Above). When the plastic nut installation fixture is in the connected state, the plastic nut is installed on the nut installation part 2 and abuts against the straightening part 3 to straighten the plastic nut to be installed; when the plastic nut installation fixture is in the use state, the push rod 1 is pushed to separate the plastic nut installed on the nut installation part 2 from the straightening part 3 and enter the installation position to complete the installation.

[0036] This plastic nut installation fixture, through the cooperation of a push rod 1, a nut mounting part 2, and a straightening part 3, enables quick and easy installation of plastic nuts. By installing the plastic nut onto the nut mounting part 2 and abutting against the straightening part 3, the plastic nut is ensured to maintain the correct installation angle while receiving a certain degree of fixed support. In this step, the user only needs to align the connecting hole of the plastic nut with the nut mounting part 2, and the straightening part 3 will assist in straightening the plastic nut. The connection is quick and convenient, and it avoids the installation misalignment that can occur with traditional connection methods. The plastic nut is then installed onto... When mounting through holes on vehicle components, pushing the push rod 1 causes the nut mounting part 2 to extend out of the straightening part 3, thereby allowing the plastic nut to be installed in the corresponding mounting position. During installation, the cooperation between the straightening part 3 and the push rod 1 ensures that the plastic nut is installed and tightened in place, thus ensuring the manufacturing precision of the vehicle. In addition, since the entire installation process does not require manual finger tightening, it avoids finger fatigue and lack of concentration that can occur with manual installation, allowing users to effectively and continuously install plastic nuts, reducing the difficulty of operation, ensuring the installation and assembly quality of plastic nuts, and improving production efficiency.

[0037] Preferably, such as Figure 5 and Figure 6 As shown, in this embodiment, the nut mounting part 2 includes a connecting rod 201, which is disposed on the end face of the first end of the push rod 1. The connecting rod 201 can be formed into a cylindrical structure, with the end of the cylindrical structure forming an arc surface to avoid damaging the connection hole of the plastic nut. The diameter of the connecting rod 201 is smaller than the size of the push rod 1, so that the end face of the first end of the push rod 1 can serve as a limiting end face when the plastic nut is connected, preventing the plastic nut from getting too close to the push rod 1 and damaging the connection hole. In addition, the diameter of the connecting rod 201 needs to match the connection hole of the plastic nut to facilitate the connection of the plastic nut.

[0038] Furthermore, such as Figure 7 As shown, when the plastic nut installation fixture is in the connected state, the first part of the connecting rod 201 is located inside the straightening part 3, and the second part of the connecting rod 201 is located outside the straightening part 3. When the plastic nut is connected to the connecting rod 201, the connecting hole of the plastic nut is aligned with the connecting rod 201 to achieve initial positioning. Then, the plastic nut is gradually fitted onto the connecting rod 201. During the fitting process, the edge of the plastic nut will abut against the edge of the straightening part 3 to achieve the straightening effect and ensure the accuracy of the installation angle of the plastic nut.

[0039] Preferably, such as Figure 3 and Figure 4As shown, in this embodiment, the end face of the first end of the straightening part 3 is formed as an annular surface 301, which includes an inner ring and an outer ring. The inner ring is closer to the nut mounting part 2 relative to the outer ring; the inner ring is closer to the second end of the push rod 1 relative to the outer ring. It can be understood that the first end and the second end of the push rod 1 can be, for example, […]. Figure 6 The upper and lower ends of the middle. The first end of the straightening part 3 can be... Figure 4 The upper end of the toroidal surface 301 comprises two rings: an inner ring and an outer ring. The inner ring can be understood as the ring closest to the axis of the straightening part 3. The end face of the first end of the straightening part 3 is not horizontal and has a certain slope. The direction of the slope can be understood as extending from the position of the outer ring towards the position of the inner ring (i.e., at the upper end of the toroidal surface 3). Figure 2 (From top to bottom in the middle). The inclined annular surface 301 can abut against the end of the plastic nut and achieve a better straightening effect.

[0040] Preferably, such as Figures 5 to 8 As shown, in this embodiment, the push rod 1 may include a first rod portion 101 and a second rod portion 102 connected to each other. The size of the first rod portion 101 is smaller than the size of the second rod portion 102. The first rod portion 101 is located inside the straightening portion 3, which is fitted onto the second rod portion 102. An installation space 4 is formed between the inner wall of the straightening portion 3 and the first rod portion 101. The installation space 4 is used to install the aforementioned elastic component. The straightening portion 3 is movably connected to the push rod 1 via the elastic component. The second rod portion 102 can be used for user gripping, for example, when connecting a plastic nut, the user grips the second rod portion 102 and connects the plastic nut to the nut mounting portion 2. The first rod portion 101 is used for connecting the straightening portion 3.

[0041] Preferably, such as Figures 5 to 8 As shown, in this embodiment, the second end of the push rod 1 is formed as a third rod portion 103, and the size of the third rod portion 103 is larger than the size of the second rod portion 102. The user can push the rod 1 by pushing the third rod portion 103. The larger size of the third rod portion 103 makes it easier for the user to push.

[0042] Preferably, such as Figures 1 to 4 , Figure 7 and Figure 8 As shown, in this embodiment, the length of the second rod 102 is greater than the length of the first rod 101. The second rod 102 is longer to facilitate gripping by the user.

[0043] Preferably, such as Figure 1 , Figure 2 , Figure 7 and Figure 8As shown, in this embodiment, the elastic component may include an elastic element 501 and a fixing element 502. The first rod portion 101 has a moving hole 104, and the straightening portion 3 has a mounting hole 302. The fixing element 502 passes through the mounting hole 302 and the moving hole 104. The elastic element 501 is disposed in the mounting space 4. The fixing element 502 is used to connect the straightening portion 3 and the push rod 1, so that when the push rod 1 moves, the straightening portion 3 will not detach from the push rod 1. The elastic element 501 is used to reset the push rod 1. When the push rod 1 moves, the elastic element 501 is compressed. The elastic element 501 may be, for example, a spring, and the fixing element 502 may be, for example, a connecting pin.

[0044] Preferably, such as Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, in this embodiment, the elastic element 501 is sleeved on the first rod portion 101. The first end of the elastic element 501 is connected to the fixing element 502, and the second end of the elastic element 501 is disposed on the end face where the second rod portion 102 connects to the first rod portion 101. When the push rod 1 moves, the fixing element 502 remains stationary, thereby keeping the position of the straightening portion 3 unchanged, and the elastic element 501 is compressed.

[0045] Preferably, such as Figures 1 to 8 As shown, in this embodiment, the mounting hole 302 can be formed as a circular hole, and the diameter of the circular hole matches that of the fastener 502 to ensure the connection stability of the fastener 502.

[0046] Preferably, such as Figures 1 to 8 As shown, in this embodiment, the moving hole 104 is formed into an oblong hole, and the fixing member 502 passes through the oblong hole. When the push rod 1 moves, the relative position of the fixing member 502 and the oblong hole changes, but the position of the fixing member 502 and the straightening part 3 remains unchanged.

[0047] Preferably, such as Figures 1 to 4 , Figure 7 and Figure 8 As shown, in this embodiment, the straightening part 3 may include a first sleeve part 303 and a second sleeve part 304 connected to each other. The size of the first sleeve part 303 corresponds to the size of the first rod part 101, and the inner diameter of the first sleeve part 303 corresponds to the diameter of the first rod part 101 to ensure a stable connection. The size of the second sleeve part 304 corresponds to the size of the second rod part 102, and the inner diameter of the second sleeve part 304 is larger than the diameter of the first rod part 101, while the inner diameter of the second sleeve part 304 corresponds to the diameter of the second rod part 102. A first portion of the first rod part 101 passes through the first sleeve part 303, and a second portion of the first rod part 101 and the second rod part 102 pass through the second sleeve part 304. Thus, since a portion of the second sleeve part 304 is fitted onto the first rod part 101, an installation space 4 can be formed.

[0048] The procedure for using this tooling for installing plastic nuts is as follows: See [link / reference] Figure 7 With the plastic nut installation fixture in the connected state, the user aligns the connecting hole of the plastic nut with the connecting rod 201 and fits the plastic nut onto the connecting rod 201 until the edge of the plastic nut abuts against the straightening part 3, thus straightening the plastic nut to the correct installation angle. The user then aligns the plastic nut installed on the connecting rod 201 with the mounting position on the vehicle component and performs initial alignment, ensuring the end of the plastic nut is in the mounting position. The user then pushes the push rod 1, causing it to move relative to the straightening part 3 until... Figure 8 The image shows the usage state. At this point, the plastic nut is separated from the centering part 3 and is fully positioned within the mounting position, indicating that the installation is complete.

[0049] This plastic nut installation fixture, through the cooperation of a push rod, a nut mounting part, and a straightening part, enables quick and easy installation of plastic nuts. By installing the plastic nut onto the nut mounting part and abutting it against the straightening part, the plastic nut is ensured at the correct installation angle and receives a certain degree of fixed support. In this step, the user only needs to align the connecting hole of the plastic nut with the nut mounting part; the straightening part assists in straightening the plastic nut, making the connection quick and convenient and avoiding installation misalignment that can occur with traditional connection methods. When installing the plastic nut into the mounting hole on the vehicle component, pushing the push rod causes the nut mounting part to extend from the straightening part, thus installing the plastic nut into the corresponding mounting position. During installation, the cooperation of the straightening part and the push rod ensures that the plastic nut is installed and tightened properly, thereby ensuring the manufacturing precision of the vehicle. Furthermore, since the entire installation process does not require manual tightening with fingers, it avoids finger fatigue and lack of concentration that can occur with manual installation. This allows users to effectively and continuously install plastic nuts, reducing operational difficulty, ensuring the installation and assembly quality of plastic nuts, and improving production efficiency.
