Description

Technical Field

[0001] This application relates to the field of automotive assembly tooling technology, and in particular to an assembly auxiliary tooling. Background Technology

[0002] In the process of automobile manufacturing, many auxiliary assembly tools are often used. For example, when assembling the outer water cutter (an important component in the installation of automobile door and window glass, mainly used to seal and fix the glass and improve the overall aesthetics of the vehicle), workers usually need to use a rubber hammer and a pressing tool to hold the outer water cutter in place, and then press the outer water cutter and the car body together to seal it, so as to prevent the window from leaking due to assembly gaps in the outer water cutter.

[0003] However, the existing assembly method has the following problems. On the one hand, the outer water cutter is usually made of soft materials such as rubber. Therefore, directly hammering the outer water cutter with a rubber mallet can easily cause the assembly stress at the corresponding position of the outer water cutter and the car body to be too concentrated, which can easily lead to damage to the car body or the outer water cutter. On the other hand, the existing crimping tools have low flexibility. During the assembly process, it is difficult for workers to adjust the crimping tools according to their actual height and the angle of force application, which greatly increases the difficulty of operation for workers. Utility Model Content

[0004] Therefore, it is necessary to provide an assembly auxiliary tooling to solve the problems of excessive stress concentration and low operational flexibility in the existing crimping method.

[0005] The assembly auxiliary tooling provided in this application includes a contouring abutment, a first connecting rod, a second connecting rod, and a pressing part. The contouring abutment has a contact surface and can be attached to the surface of the part to be pressed through the contact surface. The first connecting rod extends along a first direction and is rotatably connected to the end of the contouring abutment away from the contact surface around the first direction. The second connecting rod is hinged to the end of the first connecting rod away from the contouring abutment. The pressing part can apply a pressing force to the contouring abutment along a second direction. The first and second directions are intersecting, and the contact area between the contact surface and the part to be pressed is greater than the contact area between the pressing part and the contouring abutment.

[0006] In one embodiment, the assembly auxiliary tooling further includes a return spring, with its two ends respectively sleeved on the first link and the second link. The position when the second link and the first link are coaxially arranged is defined as the initial position. When the second link is inclined relative to the first link, the return spring can apply an elastic force to the outer wall of the second link, so that the second link has a tendency to rotate and return to the initial position.

[0007] In one embodiment, the length of the second link along its own axis is greater than the length of the first link along its own axis.

[0008] In one embodiment, the outer wall of the second link is provided with a helical groove extending helically around its own axis.

[0009] In one embodiment, the conforming abutment portion is further provided with a first pressing surface and a second pressing surface, a first connecting rod is connected to the first pressing surface, the pressing portion and the second pressing surface are pressed together, the first pressing surface, the second pressing surface and the contact surface are arranged end to end around the outer periphery of the conforming abutment portion, and the first pressing surface is perpendicular to the second pressing surface.

[0010] In one embodiment, the assembly auxiliary tooling further includes a flexible gasket, which is fixedly attached to the mating surface, and the contoured abutment portion can be attached to the surface of the part to be pressed through the flexible gasket.

[0011] In one embodiment, the assembly auxiliary tooling further includes a bearing, with the inner ring of the bearing fixedly sleeved on the first connecting rod and the outer ring of the bearing fixedly connected to the contour abutment portion, so that the first connecting rod is rotatably connected to the contour abutment portion through the bearing.

[0012] In one embodiment, one end of the first connecting rod connected to the contour abutment is provided with an annular groove arranged around the first direction, and the first connecting rod is engaged with the contour abutment through the annular groove.

[0013] In one embodiment, the assembly auxiliary tooling further includes a hinge pin, one of the first link and the second link is fixed with a retaining plate, and the other is provided with a retaining groove extending along a first direction. The retaining plate is clamped between the side walls opposite to the retaining groove, and the hinge pin passes through the retaining plate and the side walls opposite to the retaining groove, so that the retaining plate can be rotatably connected to the side walls opposite to the retaining groove about the axis of the hinge pin.

[0014] In one embodiment, the first direction and the second direction are set perpendicularly.

[0015] Compared with the prior art, the assembly auxiliary tooling provided in this application can apply pressure along the first direction to the conformal abutment part through the second link and the first link when pressing the crimping part, so as to prevent the crimping part from loosening. Then, the crimping part applies a crimping force along the second direction to the crimping part so as to complete the assembly of the crimping part.

[0016] Because the first and second directions are intersecting, that is, the first and second directions are not parallel, the crimping part and the connecting rod part (including the first connecting rod and the second connecting rod) will not interfere with each other, which effectively improves the assembly success rate of the parts to be crimped.

[0017] Furthermore, since the contact area between the bonding surface and the part to be pressed is greater than the contact area between the pressing part and the contoured abutment part, by setting the contoured abutment part, the pressure exerted by the pressing part on the part to be pressed can be dispersed, thereby reducing the pressure and alleviating stress concentration, and preventing damage to the part to be pressed.

[0018] Furthermore, since the first link is rotatably connected to the end of the conformal abutment portion away from the contact surface about a first direction, and the second link is hinged to the end of the first link away from the conformal abutment portion, by rotating the first and second links about the first direction and rotating the second link about the hinge point, the end of the second link away from the first link can reach any position on the spherical surface. Here, the spherical surface is a sphere with the hinge point as its center and the second link as its radius. This greatly improves the range of motion and flexibility of the assembly auxiliary tool.

Detailed Implementation

[0024] In the process of automobile manufacturing, many auxiliary assembly tools are often used. For example, when assembling the outer water cutter (an important component in the installation of automobile door and window glass, mainly used to seal and fix the glass and improve the overall aesthetics of the vehicle), workers usually need to use a rubber hammer and a pressing tool to hold the outer water cutter in place, and then press the outer water cutter and the car body together to seal it, so as to prevent the window from leaking due to assembly gaps in the outer water cutter.

[0025] However, the existing assembly method has the following problems. On the one hand, the outer water cutter is usually made of soft materials such as rubber. Therefore, directly hammering the outer water cutter with a rubber mallet can easily cause the assembly stress at the corresponding position of the outer water cutter and the car body to be too concentrated, which can easily lead to damage to the car body or the outer water cutter. On the other hand, the existing crimping tools have low flexibility. During the assembly process, it is difficult for workers to adjust the crimping tools according to their actual height and the angle of force application, which greatly increases the difficulty of operation for workers.

[0026] Please see Figures 1-3 To address the issues of excessive stress concentration and low operational flexibility in existing crimping methods, this application provides an assembly auxiliary tooling. This tooling includes a contoured abutment portion 100, a first connecting rod 200, a second connecting rod 300, and a crimping portion 400. The contoured abutment portion 100 has a contact surface 110, which allows it to be attached to the surface of the component 500 to be crimped (including but not limited to components such as external water-cooling strips and sealing strips) via the contact surface 110. The first connecting rod 200 extends along a first direction and is rotatably connected to the end of the contoured abutment portion 100 away from the contact surface 110. The second connecting rod 300 is hinged to the end of the first connecting rod 200 away from the contoured abutment portion 100.

[0027] The crimping portion 400 can apply a crimping force to the contour abutment portion 100 along the second direction. The first and second directions are arranged intersectingly, and the contact area between the contact surface 110 and the workpiece 500 to be crimped is greater than the contact area between the crimping portion 400 and the contour abutment portion 100.

[0028] It should be noted that the crimping part 400 can be a hydraulic press or a rubber hammer.

[0029] Furthermore, it should be noted that the instruction manual includes... Figure 1 In the diagram, X represents the first direction and Y represents the second direction.

[0030] When pressing the crimping part 500, the second connecting rod 300 and the first connecting rod 200 can apply pressure along the first direction to the conformal abutment part 100 to prevent the crimping part 500 from loosening. Then, the crimping part 400 applies a crimping force along the second direction to the crimping part 500 to complete the assembly of the crimping part 500.

[0031] Since the first direction and the second direction are intersecting, that is, the first direction and the second direction are not parallel, the crimping part 400 and the connecting rod part (including the first connecting rod 200 and the second connecting rod 300) will not interfere with each other, which effectively improves the assembly success rate of the part to be crimped 500.

[0032] Furthermore, since the contact area between the bonding surface 110 and the workpiece 500 to be pressed is greater than the contact area between the pressing part 400 and the contoured abutment part 100, by providing the contoured abutment part 100, the pressure exerted by the pressing part 400 on the workpiece 500 to be pressed can be dispersed, thereby reducing the pressure and alleviating stress concentration, and preventing damage to the workpiece 500 to be pressed.

[0033] Furthermore, since the first link 200 is rotatably connected to the end of the contour abutment 100 away from the contact surface 110 about a first direction, and the second link 300 is hinged to the end of the first link 200 away from the contour abutment 100, by rotating the first link 200 and the second link 300 about the first direction, and by rotating the second link 300 about the hinge point, the end of the second link 300 away from the first link 200 can reach any position on the spherical surface. Here, the spherical surface is a sphere with the hinge point as its center and the second link 300 as its radius. This greatly improves the range of motion and flexibility of the assembly auxiliary tool.

[0034] In one embodiment, the first direction and the second direction are arranged perpendicularly.

[0035] This configuration allows for a clamping effect on the contour abutment 100 in mutually perpendicular directions, preventing the contour abutment 100 from shifting during use.

[0036] However, this is not the only one. In other embodiments, the first direction and the second direction can also be set at various angles such as 80 degrees, 70 degrees, or 60 degrees, which will not be listed here.

[0037] Furthermore, in one embodiment, as Figure 2As shown, the contoured abutment portion 100 is also provided with a first pressing surface 120 and a second pressing surface 130. The first connecting rod 200 is connected to the first pressing surface 120. The pressing portion 400 and the second pressing surface 130 are pressed together. Around the circumference of the contoured abutment portion 100, the first pressing surface 120, the second pressing surface 130 and the contact surface 110 are connected end to end. The first pressing surface 120 is perpendicular to the second pressing surface 130.

[0038] With this configuration, the contact surface 110 is positioned between the first pressing surface 120 and the second pressing surface 130, which facilitates the application of pressing forces by the first pressing surface 120 and the second pressing surface 130 to the pressing surface. Furthermore, since the first pressing surface 120 and the second pressing surface 130 are perpendicular, it is beneficial for the first connecting rod 200 and the pressing part 400 to form perpendicularly positioned pressing forces on the contour abutment part 100.

[0039] Furthermore, in one embodiment, the cross-section of the mating surface 110 is curved.

[0040] However, this is not the only one. In other embodiments, the cross-section of the mating surface 110 may also be linear or other irregular, depending mainly on the surface shape of the component to be pressed 500.

[0041] In one embodiment, the assembly auxiliary tooling further includes a flexible gasket (not shown), which is fixedly attached to the mating surface 110, and the contoured abutment portion 100 can be attached to the surface of the part to be pressed 500 through the flexible gasket.

[0042] Specifically, the flexible gasket can be made of rubber, silicone, soft plastic, etc., which will not be listed here.

[0043] More specifically, the flexible gasket can be snapped, bonded, or connected to the conformal abutment portion 100 by fasteners.

[0044] This configuration allows the flexible pad to deform to fit the uneven surface of the component 500, increasing the contact area between the contoured abutment 100 and the surface of the component 500, and improving the fit between the contoured abutment 100 and the component 500.

[0045] In one embodiment, such as Figure 3 As shown, the assembly auxiliary tooling also includes a bearing 700. The inner ring of the bearing 700 is fixedly sleeved on the first connecting rod 200, and the outer ring of the bearing 700 is fixedly connected to the contour abutment part 100, so that the first connecting rod 200 is rotatably connected to the contour abutment part 100 through the bearing 700.

[0046] This design reduces the difficulty of connecting the first link 200 and the contoured abutment part 100. Furthermore, the bearing 700 has low rotational friction, which helps to improve the rotational flexibility of the first link 200.

[0047] In another embodiment, one end of the first connecting rod 200 connected to the contour abutment portion 100 is provided with an annular groove (not shown) arranged around the first direction (axial direction of the first connecting rod 200), and the first connecting rod 200 is engaged with the contour abutment portion 100 through the annular groove.

[0048] This design reduces the number of parts required for assembly auxiliary tooling, thereby lowering manufacturing costs.

[0049] In one embodiment, such as Figures 1-3 As shown, the assembly auxiliary tooling also includes a hinge pin 600. One of the first connecting rod 200 and the second connecting rod 300 is fixed with a clamping plate 210, and the other is provided with a groove 310 extending along a first direction. The clamping plate 210 is clamped between the opposite side walls of the groove 310. The hinge pin 600 passes through the clamping plate 210 and the opposite side walls of the groove 310, so that the clamping plate 210 can be rotatably connected to the opposite side walls of the groove 310 around the axis of the hinge pin 600.

[0050] Thus, the clamping plate 210 is sandwiched between the opposing side walls of the clamping slot 310, which helps to improve the connection strength between the first link 200 and the second link 300. Furthermore, the second link 300 can drive the first link 200 to rotate around the first direction.

[0051] Specifically, the card plate 210 and the first connecting rod 200 (or the second connecting rod 300) are welded or integrally formed, and the second connecting rod 300 (or the first connecting rod 200) can be machined to form the card slot 310 by turning.

[0052] However, this is not the only embodiment. In other embodiments, the slot 310 may also have only one side wall.

[0053] Furthermore, in one embodiment, the slot 310 extends radially through the outer wall of the second link 300 (or the first link 200), thereby allowing the card plate 210 to have a larger range of rotation relative to the slot 310.

[0054] In one embodiment, the assembly auxiliary tooling further includes a return spring (not shown). The two ends of the return spring are respectively sleeved on the first link 200 and the second link 300. The position when the second link 300 and the first link 200 are coaxially arranged is defined as the initial position. When the second link 300 is inclined relative to the first link 200, the return spring can apply an elastic force to the outer wall of the second link 300 so that the second link 300 has a tendency to rotate toward the initial position.

[0055] In this way, when the second link 300 rotates to the preset position, the bending force applied to the second link 300 by the worker and the elastic force applied to the second link 300 by the return spring can be kept in balance, thereby enabling the second link 300 to remain stable during the assembly process.

[0056] In one embodiment, such as Figures 1-3 As shown, the outer wall of the second connecting rod 300 is provided with a spiral groove 320 extending spirally around its own axis.

[0057] This design increases the surface roughness of the second link 300, thereby increasing the friction when the hand grips the second link 300 and preventing the second link 300 from sliding relative to the worker's hand, which would affect the assembly operation.

[0058] However, this is not the only embodiment. In other embodiments, the outer periphery of the second link 300 may also be provided with an anti-slip rubber sleeve.

[0059] In one embodiment, such as Figures 1-3 As shown, the length of the second link 300 along its own axis is greater than the length of the first link 200 along its own axis.

[0060] Understandably, the worker controls his own swing and the rotation of the first link 200 through the second link 300. Therefore, by increasing the length of the second link 300, it is easier for the worker to hold the assembly auxiliary tools.

[0061] However, this is not the only possibility. In other embodiments, the lengths of the second link 300 and the first link 200 may also be equal.
