Description

Technical Field

[0001] This application relates to the field of vehicle manufacturing technology, specifically to a tooling. Background Technology

[0002] To ensure good assemblability and excellent appearance, the wiper cover below the windshield is designed to be snap-fitted into the windshield.

[0003] In related technologies, the installation of wiper covers mainly relies on manual assembly by pressing and hammering the wiper covers with the palms and fists. Due to the limited space for the arrangement of the wiper shaft and the windshield, the installation space for wiper covers is small. Furthermore, since the wiper shaft and other structures are located within the installation area, workers are very likely to collide with the wiper shaft and other structures during the installation process, which can lead to personal injury. Utility Model Content

[0004] In view of this, this application provides a tooling that can be used to assist in the installation of windshield wiper covers, thereby reducing the probability of personnel injury during the installation of windshield wiper covers.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A tooling fixture is used to assist in mounting a first component onto a second component; the tooling fixture includes:

[0007] The gripping part has a gripping surface for gripping;

[0008] A rolling portion is connected to the gripping portion and has a rolling surface; wherein the portion of the rolling portion forming the rolling surface is movable relative to the portion of the gripping portion forming the gripping surface.

[0009] Optionally, the tooling further includes:

[0010] The pressing part is connected to the gripping part; the pressing part and the rolling part are distributed on opposite sides of the gripping part, and the pressing part has a pressing surface on the side away from the rolling part that can abut against the first component.

[0011] Optionally, the rolling surface is provided with a first protective pad, and / or the pressing surface is provided with a second protective pad.

[0012] Optionally, the gripping part is configured as a rod, and the rolling part and the pressing part are distributed at both ends of the gripping part along its length.

[0013] Optionally, in the arrangement direction of the pressing part and the rolling part, the surface of the rolling part away from the pressing part is the bearing surface; the area of ​​the bearing surface is larger than the area of ​​the radial cross section of the gripping part.

[0014] Optionally, the gripping part includes a fixed rod and a rotating sleeve. The fixed rod is fixedly connected to the rolling part, and the rotating sleeve is rotatably sleeved on the outer periphery of the fixed rod, and the rotating sleeve has the gripping surface.

[0015] Optionally, the rolling part includes a rolling seat and a rolling block. The rolling seat is fixedly connected to the gripping part, and the rolling block is rotatably sleeved on the outer periphery of the rolling seat, and the rolling block has the rolling surface.

[0016] Optionally, a bearing is fitted around the outer periphery of the rolling seat, and the rolling block is the outer ring of the bearing.

[0017] Optionally, the rolled surface is detachably connected to a first protective pad;

[0018] The outer ring is provided with an installation groove, which is arranged around the outer ring and used to install the first protective pad. The thickness of the first protective pad is greater than the depth of the installation groove.

[0019] Optionally, the pressing surface is larger than the area of ​​the radial cross-section of the gripping portion.

[0020] This application provides a tooling that includes a gripping part and a rolling part. When using this tooling to assist in the installation of the wiper cover, the operator can hold the gripping part and control the rolling part to abut against the surface of the connecting area A of the wiper cover. Then, the rolling part of the tooling is controlled to move along a preset trajectory, and a force towards the vehicle body is applied to the wiper cover through the tooling.

[0021] During the above process, the operator's point of force application changed from the original wiper cover connection area A to the gripping part of the tool. This change allows the operator's hands to be kept away from sharp objects around connection area A, thereby effectively reducing the risk of injury.

[0022] Furthermore, during the aforementioned process, the portion of the roller forming the rolling surface can move relative to the portion of the gripping portion forming the gripping surface. This arrangement minimizes the force exerted by the rolling surface on the wiper cover in the same direction as the tooling movement. This effectively prevents the wiper cover from shifting along the tooling's movement direction, thus preventing the wiper cover from disengaging from its connection position and ultimately ensuring a precise connection of the wiper cover.

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] First, it should be noted that the tooling 100 in this embodiment is suitable for assisting in the installation of the first component on the second component, and the first component and the second component are snapped together. That is, the tooling 100 in this embodiment is suitable for assisting in the assembly of two components that are snapped together. For example, the first component and the second component can be a car body trim panel, respectively; or, the first component and the second component can be a wiper cover 400 and a car body, respectively.

[0036] To make it easier to understand, the following explanation will use the wiper cover 400 as the first component and the car body as the second component as an example.

[0037] Currently, to ensure good assemblability and excellent appearance, the wiper cover 400 below the windshield 200 is designed to snap-fit ​​with the windshield 200. Specifically, as shown... Figure 1 As shown, the wiper cover 400 is snapped into the glass clip 300 installed on the vehicle body via a snap-fit ​​structure to achieve the connection between the wiper cover 400 and the vehicle body.

[0038] Based on the above structure, in related technologies, such as Figure 1 As shown, when assembling the wiper cover 400, it is mainly done manually by pressing and hammering the wiper cover 400 with the palm and fist.

[0039] However, due to the arrangement requirements of the wiper shaft 500 and the windshield 200, the assembly and operation space for the wiper cover 400 is small, and, as Figure 2 As shown, the connection area A between the wiper cover 400 and the vehicle body is relatively close to the wiper shaft 500. This makes it very easy for workers to bump into structures such as the wiper shaft 500 during the installation of the wiper cover 400, which could lead to personal injury.

[0040] In view of the above problems, this application provides a tooling 100, which can change the point of force application of the operator, thereby avoiding the contact of the operator's hands with sharp objects (including but not limited to the wiper shaft 500) around the connection area A during the assembly process of the wiper cover 400, thereby reducing the probability of personnel injury.

[0041] like Figure 3 As shown, the tooling 100 in this embodiment includes a gripping part 1 and a rolling part 2.

[0042] The gripping part 1 is the area that the operator holds during the use of the tool 100.

[0043] The rolling part 2 is a tooling 100 that can act on the connection area of ​​the wiper cover 400 during use to transmit force to the wiper cover 400, so that the wiper cover 400 is pressed and connected to the vehicle body.

[0044] In this embodiment, the rolling part 2 is connected to the gripping part 1.

[0045] The connection between the rolling part 2 and the gripping part 1 can be achieved through a connecting structure. That is, the rolling part 2 and the gripping part 1 are set as two independent parts, and the two can be connected by a connecting structure. This connecting structure can be a threaded connection structure or a snap-fit ​​structure, etc.

[0046] The connection between the rolling part 2 and the gripping part 1 can also be achieved by integrally molding at least a portion of the structure of the rolling part 2 with the gripping part 1.

[0047] Furthermore, the rolling portion 2 has a rolling surface, and the portion of the rolling portion 2 that forms the rolling surface is movable relative to the portion of the gripping portion 1 that forms the gripping surface. That is, the rolling surface is configured such that when the tooling 100 moves relative to the wiper cover 400, the rolling surface abuts against the wiper cover 400 and has static friction with the wiper cover 400.

[0048] Figure 4 The diagram shown illustrates the tooling 100 in its first usage state, which refers to the state of the tooling 100 when the rolling part 2 of the tooling 100 is used to assist in the installation of the wiper cover 400. Figure 4 As shown, when using the rolling part 2 of the tooling 100 to assist in the installation of the wiper cover 400, the operator can hold the grip part 1 of the tooling 100 and precisely control the rolling part 2 to ensure it is in close contact with the surface of the connection area A of the wiper cover 400. After the contact is completed, the operator needs to further control the rolling part 2 of the tooling 100 to move it smoothly along a pre-set trajectory. This pre-set trajectory strictly follows the line connecting the start point and the end point of the connection between the wiper cover 400 and the vehicle body to ensure the accuracy of the installation path. During the movement of the rolling part 2, the tooling 100 applies a stable force towards the vehicle body to the wiper cover 400, thereby pushing the wiper cover 400 to complete the installation smoothly.

[0049] During the above process, the position where the operator applies force changes from the original connection area A of the wiper cover 400 to the gripping part 1 of the tool 100. This change allows the operator's hands to be kept away from sharp objects around the connection area A, thereby effectively reducing the risk of injury.

[0050] Furthermore, during the aforementioned process, when the tooling 100 moves relative to the wiper cover 400, the portion of the rolling part 2 used to form the rolling surface can be displaced relative to the portion of the gripping part 1 used to form the gripping surface (the gripping surface being the surface in the gripping part 1 used for the operator's hand to grip). This arrangement minimizes the force exerted on the wiper cover 400 by the rolling surface in the same direction as the tooling 100's movement. In this way, it effectively prevents the wiper cover 400 from shifting along the direction of the tooling 100's movement, thereby preventing the wiper cover 400 from disengaging from its connection position and ultimately ensuring a precise connection of the wiper cover 400.

[0051] In some embodiments, such as Figure 3 As shown, the tooling 100 also includes a pressing part 3.

[0052] The pressing part 3 is connected to the gripping part 1.

[0053] Optionally, the pressing part 3 and the holding part 1 can be two independent components, which are fixedly connected by bolts or welding. Alternatively, the connection between the pressing part 3 and the holding part 1 can be achieved by integrally molding the pressing part 3 and the holding part 1.

[0054] Figure 5 The diagram shows the tooling 100 in a second usage state, which refers to the state of the tooling 100 when the pressing part 3 of the tooling 100 is used to assist in the installation of the wiper cover 400. Figure 5 As shown, when using the pressing part 3 of the tooling 100 to assist in the installation of the wiper cover plate 400, the operator can hold the gripping part 1 of the tooling 100 and control the pressing surface of the pressing part 3 to abut against the position of the wiper cover plate 400 where the snap-fit ​​structure is provided. Then, press or hammer the surface of the tooling 100 away from the wiper cover plate 400 to move the wiper cover plate 400 toward the vehicle body, thereby completing the installation of the wiper cover plate 400.

[0055] Understandably, compared to using the rolling part 2 to assist in installing the wiper cover 400, using the pressing part 3 provides greater force to the wiper cover 400. Based on this, in the usage scenario of the tooling 100 in this embodiment, a phased operation strategy can be adopted: First, the rolling part 2 is used to assist in the approximate installation of the wiper cover 400, ensuring that most of the structure is initially in place; then, the pressing part 3 is used to precisely assist in the installation of those snap-fit ​​structures that cannot be effectively connected by the rolling part 2, ensuring that these snap-fit ​​structures are firmly connected. In this way, the assembly process can be efficiently advanced, ensuring assembly efficiency, and all snap-fit ​​structures between the wiper cover 400 and the vehicle body can be securely and effectively connected, thereby improving assembly quality.

[0056] Furthermore, continuing as Figure 3As shown, the pressing part 3 and the rolling part 2 are distributed on opposite sides of the gripping part 1, and the pressing part 3 has a pressing surface on the side away from the rolling part 2 that can abut against the wiper cover 400. In this way, mutual interference between the pressing part 3 and the rolling part 2 during use can be effectively avoided, thereby ensuring the normal use of the tooling 100.

[0057] In some embodiments, the rolling surface is provided with a first protective pad 203.

[0058] For example, the first protective pad 203 can be a silicone pad or a rubber pad.

[0059] The first protective pad 203 can isolate the hard surface of the rolling part 2, preventing damage to the product surface during the assembly process.

[0060] In some embodiments, the pressing surface is provided with a second protective pad 302.

[0061] For example, the second protective pad 302 can be a silicone pad or a rubber pad.

[0062] The second protective pad 302 can isolate the hard surface of the pressing part 3, preventing damage to the product surface during the assembly process.

[0063] In some embodiments, the gripping part 1 is rod-shaped, and the rolling part 2 and the pressing part 3 are distributed at both ends of the gripping part 1 along its length.

[0064] The rod-shaped grip 1 is more in line with the gripping habits of operators, making it easier for them to hold it firmly; on the other hand, because of its small size, the tool 100 can function normally and carry out operations smoothly even in environments with limited operating space.

[0065] It should be understood that setting the grip part 1 as a rod is only one possible implementation of the grip part 1, but this application is not limited to this. For example, the grip part 1 can also be set as a ring, etc.

[0066] Furthermore, in some embodiments, the pressing surface is larger than the radial cross-sectional area of ​​the gripping portion 1. This design increases the contact area between the pressing portion 3 and the wiper cover 400, thereby effectively preventing the wiper cover 400 from being subjected to excessive local pressure when the wiper cover 400 is installed with the assistance of the pressing portion 3, and thus preventing the wiper cover 400 from being damaged due to uneven local stress.

[0067] For example, such as Figure 3As shown, the pressing part 3 includes a pressing seat 301, which is fixedly connected to the holding part 1. This fixed connection can be achieved by means of threaded structure or welding, or by molding the two together as one piece.

[0068] Continue as Figure 3 As shown, the pressing seat 301 is cylindrical, and the pressing seat 301 is coaxially arranged with the rod-shaped grip 1. The end face of the pressing seat 301 away from the grip 1 is the pressing surface; and the radius of the outer peripheral edge of the pressing surface is greater than the radius of the radial section of the grip 1.

[0069] Understandably, without considering other factors, the larger the pressing surface, the smaller the local pressure on the wiper cover 400 when using the pressing part 3 to assist in the installation of the wiper cover 400. Based on this, in actual implementation, the pressing surface cannot be set too large, otherwise it will be detrimental to the assembly of the wiper cover 400.

[0070] Based on the above, in some embodiments, the area of ​​the pressing surface is set to be larger than the radial cross-sectional area of ​​the gripping part 1, but smaller than the actual contact area between the hand and the wiper cover 400 when the operator uses their hand to hammer the wiper cover 400 to install it onto the vehicle body. This design significantly reduces the possibility of the wiper cover 400 being damaged by pressure. Furthermore, compared to the operation method of directly pressing or hammering the wiper cover 400 with the hand in related technologies, this design increases the local pressure borne by the wiper cover 400 during assembly, thereby effectively improving assembly efficiency.

[0071] Furthermore, such as Figure 3 As shown, in the arrangement direction of the pressing part 3 and the rolling part 2, the surface of the rolling part 2 away from the pressing part 3 is the bearing surface 204. This bearing surface 204 refers to the surface used to receive the force applied by the operator when the wiper cover 400 is installed with the assistance of the pressing part 3, so as to move the wiper cover 400 towards the vehicle body. The area of ​​the bearing surface 204 is larger than the radial cross-sectional area of ​​the gripping part 1.

[0072] In this configuration, when using the pressing part 3 to assist in the installation of the wiper cover 400, after the pressing surface of the pressing part 3 abuts against the corresponding position of the wiper cover 400, the operator can press or hammer the bearing surface 204 so that the force is transmitted to the wiper cover 400 through the tooling 100, thereby completing the installation of the wiper cover 400. During this process, the aforementioned design of the bearing surface 204 significantly increases the contact area between the operator's hand and the tooling 100, effectively reducing the pressure exerted by the tooling 100 on the hand, and thus greatly alleviating the operator's discomfort.

[0073] As mentioned above, when the wiper cover 400 is installed with the assistance of the rolling part 2, the part of the rolling part 2 used to form the rolling surface can be displaced relative to the part of the gripping part 1 used to form the gripping surface.

[0074] In some embodiments, the gripping part 1 includes a fixed rod and a rotating sleeve. The fixed rod is fixedly connected to the rolling part 2, and the rotating sleeve is rotatably sleeved on the outer periphery of the fixed rod, and the rotating sleeve has a gripping surface for gripping. In this way, during the process of using the rolling part 2 to assist in the installation of the wiper cover 400, when the tooling 100 moves relative to the wiper cover 400, the rotating sleeve can rotate relative to the fixed rod, thereby allowing the portion of the rolling part 2 used to form the rolling surface to be displaced relative to the portion of the gripping part 1 used to form the gripping surface.

[0075] In other embodiments, the rolling part 2 includes a rolling seat 201 and a rolling block. The rolling seat 201 is fixedly connected to the gripping part 1, and the rolling block is rotatably sleeved on the outer periphery of the rolling seat 201, and the rolling block has a rolling surface. In this way, during the process of using the rolling part 2 to assist in the installation of the wiper cover 400, when the tooling 100 moves relative to the wiper cover 400, the rolling block can rotate relative to the rolling seat 201, thereby allowing the portion of the rolling part 2 used to form the rolling surface to be displaced relative to the portion of the gripping part 1 used to form the gripping surface.

[0076] Furthermore, in some embodiments, a bearing 202 is fitted around the outer periphery of the rolling seat 201, and the outer ring of the bearing 202 forms the aforementioned rolling block. In this configuration, since there is rolling friction between the inner and outer rings of the bearing 202, the frictional force when the rolling block rotates relative to the fixed seat can be reduced, thereby further reducing the force exerted by the rolling surface on the wiper cover 400 in the same direction as the movement of the tooling 100.

[0077] Furthermore, such as Figure 3 As shown, the rolling surface is parallel to the arrangement direction of the rolling part 2 and the pressing part 3. This arrangement helps to avoid the overlap between the rolling surface and the bearing surface 204, so that the rolling surface and the bearing surface 204 can be adapted to their respective needs, thus making the overall design of the tooling 100 more reasonable.

[0078] Furthermore, based on the aforementioned use of the outer ring of bearing 202 to form a rolling block, in some embodiments, the first protective pad 203 is detachably connected to the rolling surface. This makes it easier to replace the first protective pad 203 when it ages or is damaged, thus facilitating the maintenance of tooling 100.

[0079] In an exemplary embodiment, an mounting groove is provided on the outer ring, which surrounds the outer ring and is used to mount the first protective pad 203. The thickness of the first protective pad 203 is greater than the depth of the mounting groove. In this way, the mounting groove limits the first protective pad 203, effectively preventing the first protective pad 203 from falling off.
