Description

Technical Field

[0001] The utility model relates to the technical field of automobile manufacturing and assembly, in particular to an installation device for assembling vehicle door rubber strips. Background Art

[0002] During the automobile manufacturing process, door sealant strips are installed to hide the welding marks on the front and rear doors of the car. After installation, the door sealant strips have the sealing effects of waterproofing, sealing, sound insulation, dustproofing, shock absorption, warmth retention, aging resistance, and chemical corrosion resistance. However, during the assembly of the sealant strips in automobile manufacturing, the edge of the door frame is squeezed by welding, and the edge is larger at the top and smaller at the bottom. In order to achieve a better sealing effect, the sealing strip installation groove is designed with a small opening and a large bottom. Usually, when installing the strips, the staff will first select a location of the door strip and initially embed the installation groove into the door frame to form a preliminary solidification. Then, they will manually arrange the strips and squeeze them along the door frame until all the strips are squeezed into the installation groove, thus completing the door sealant strip assembly work. However, since this operation is manual and the strips are squeezed by fingers, it is often not squeezed into place at the corners of the door, resulting in "excess" strips and requiring rework. Such long-term operation can also cause problems such as wrist joint pain in employees.

[0003] Therefore, in view of this, the inventor proposes an installation device for assembling vehicle door rubber strips to solve the above technical problems. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is to provide an installation device for assembling vehicle door rubber strips, which facilitates the installation of the rubber strips, thereby improving the installation efficiency of the rubber strips and reducing the work intensity of installing the rubber strips.

[0005] In order to achieve the above purpose, the technical solution adopted by the present utility model is as follows:

[0006] A mounting device for assembling a vehicle door rubber strip comprises a first body and a second body, wherein the first body and the second body are fixed to each other, a connecting shaft is fixedly provided on the first body, an auxiliary wheel is connected to the connecting shaft, and the auxiliary wheel is capable of rotating;

[0007] A first installation cavity is defined within the first body, a slide rod is slidably connected to the first installation cavity, and one end of the slide rod extends out of the first body and is connected to a tooling extrusion wheel;

[0008] A second installation cavity is defined in the second body. A driving assembly is disposed in the second installation cavity. The driving assembly is connected to the other end of the slide bar and is used to drive the slide bar to slide.

[0009] Furthermore, at least one side wheel extrusion unit is provided on the first body.

[0010] Furthermore, the side wheel extrusion unit includes a first connecting rod, a second connecting rod and a side pulley, one end of the first connecting rod is connected to the first body, the other end of the first connecting rod is connected to the second connecting rod, and the end of the second connecting rod is connected to the connecting shaft;

[0011] A shaft rod is provided at the connection between the first connecting rod and the second connecting rod, the axis of the shaft rod is parallel to the axis of the sliding rod, the side pulley is installed on the shaft rod, and the side pulley is rotatable.

[0012] According to the above technical solution, in the side wheel extrusion unit, the first connecting rod, the second connecting rod and the shaft rod are used to support the side pulleys. By setting two side wheel extrusion units, the two side pulleys are combined with the door sill edge position. The two side pulleys can be used to slide on both sides of the rubber strip after and during the installation of the rubber strip, so as to assist the work of the tooling extrusion wheel.

[0013] Furthermore, a first mounting block and a second mounting block are fixedly disposed in the second mounting cavity, and the first mounting block and the second mounting block are used for mounting the drive assembly.

[0014] According to the above technical solution, the first mounting block and the second mounting block provide a stable support platform for the drive assembly, ensuring the stability and reliability of the drive assembly during operation.

[0015] Furthermore, the driving assembly includes a rotating wheel, a cam, a cam rod and a driving unit, wherein the rotating wheel is rotatably mounted on the sliding rod, the cam rod is rotatably connected between the first mounting block and the second mounting block, the cam is coaxially fixed to the cam rod, and the cam is in contact with the rotating wheel;

[0016] The driving unit is used to drive the cam rod to rotate.

[0017] According to the above technical solution, when the driving unit receives the start signal, it starts working and drives the cam rod to rotate. As the cam rod rotates, the cam also rotates and contacts the rotating wheel. The contour shape of the cam enables it to generate a force that pushes the rotating wheel when it contacts the rotating wheel. This force is transmitted to the sliding rod through the rotating wheel. After receiving the driving force from the rotating wheel, the sliding rod begins to slide along the axial direction of the first mounting cavity.

[0018] Furthermore, the driving unit includes a transmission shaft rotatably connected to the second mounting block and a motor fixed to the second mounting block, a first bevel gear is coaxially provided at the end of the transmission shaft, and a driven gear is coaxially fixed on the transmission shaft;

[0019] The output shaft of the motor is coaxially connected to a driving gear, and the driving gear is meshed with the driven gear;

[0020] One end of the cam rod is coaxially connected to a second bevel gear, and the first bevel gear is meshed with the second bevel gear.

[0021] According to the above technical solution, when the motor starts working, the output shaft drives the driving gear to rotate. Since the driving gear is engaged with the driven gear, the power from the motor is transmitted to the driven gear and the transmission shaft. The transmission shaft rotates accordingly, and the cam rod driven by the first bevel gear and the second bevel gear also rotates with the rotation of the second bevel gear.

[0022] Furthermore, the sliding rod includes a rod body, a ring and a connector, the ring is coaxially fixed on the rod body, the connector is fixedly arranged at one end of the rod body, the other end of the rod body is connected to the tooling extrusion wheel, and the rotating wheel is rotatably installed on the connector.

[0023] Furthermore, an elastic member is provided in the first installation cavity, one end of the elastic member is connected to the inner wall of the first body, and the other end of the elastic member is connected to the ring, and the elastic member has a tendency to drive the ring closer to the second body.

[0024] Furthermore, the axis of the auxiliary wheel is perpendicular to the axes of the tooling extrusion wheel and the side pulley.

[0025] According to the above technical solution, when the cam rotates, it can drive the slide rod to slide along the axial direction of the first installation cavity, and then drive the tooling extrusion wheel to approach the door rubber strip. When the tooling extrusion wheel contacts the door rubber strip, it starts to extrude and install it; at this time, the elastic member plays a buffering and resetting role in this process. When the thrust of the cam on the rotating wheel decreases, the elastic member will drive the ring (and the slide rod) to reset, so that the tooling extrusion wheel returns to its initial position. As the cam continues to rotate, the slide rod and the tooling extrusion wheel will continue to reciprocate, and the tooling extrusion wheel will knock and squeeze the door rubber strip to ensure that the rubber strip can be evenly installed in the installation groove of the door frame.

[0026] Furthermore, a control switch is provided on the second body.

[0027] According to the above technical solution, the control switch is connected to the motor control and is used to start or stop the motor.

[0028] Beneficial effects of the utility model:

[0029] The utility model realizes efficient installation of vehicle door rubber strips through the tooling extrusion wheel, the side wheel extrusion unit and the driving assembly. Driven by the driving assembly, the tooling extrusion wheel can reciprocate along the installation groove of the vehicle door frame, uniformly squeeze the rubber strip, and ensure that the rubber strip can be completely embedded in the installation groove. At the same time, the provision of the side wheel extrusion unit further enhances the stability of the installation and can effectively prevent the rubber strip from slipping during the installation process, which not only improves the installation efficiency, but also improves the assembly quality of the vehicle door rubber strip, with a compact structure and strong practicality.

DETAILED DESCRIPTION

[0037] The following describes the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are intended solely to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0038] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention. Therefore, the drawings only show components related to the present invention and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0039] This embodiment provides an installation device for assembling a door rubber strip, such as Figures 1 to 5 As shown, the first body 1 and the second body 2 are fixed together by bolts. A connecting shaft 3 is fixed on the top of the first body 1, and an auxiliary wheel 4 is connected to the connecting shaft 3. The auxiliary wheel 4 can rotate.

[0040] like Figure 3 As shown, a first mounting cavity 11 is provided in the first housing 1, and a slide bar 5 is slidably connected in the first mounting cavity 11. The slide bar 5 can move laterally. One end of the slide bar 5 (i.e. Figure 3 The left end of the middle slide bar 5) extends out of the first body 1 and is connected to the tooling extrusion wheel 6; a second installation cavity 21 is opened in the second body 2, and a drive component 7 is set in the second installation cavity 21. The drive component 7 is connected to the other end of the slide bar 5 (i.e. Figure 3 The right end of the middle slide bar 5 is connected to drive the slide bar 5 to slide.

[0041] Furthermore, at least one side wheel extrusion unit 8 is provided on the first body 1; in this embodiment, Figure 1 As shown, there are two side wheel extrusion units 8, which are respectively arranged on the left and right sides of the first body 1; the side wheel extrusion unit 8 includes a first connecting rod 81, a second connecting rod 82 and a side pulley 83, one end of the first connecting rod 81 is connected to the first body 1, the other end of the first connecting rod 81 is connected to the second connecting rod 82, and the end of the second connecting rod 82 is connected to the connecting shaft 3; a shaft rod 84 is provided at the connection between the first connecting rod 81 and the second connecting rod 82, the axis of the shaft rod 84 is parallel to the axis of the slide rod 5, and the side pulley 83 is installed on the shaft rod 84, and the side pulley 83 can rotate.

[0042] According to the above technical solution, the first connecting rod 81, the second connecting rod 82 and the shaft rod 84 are used to support the side pulley 83. By setting two side wheel extrusion units 8, the two side pulleys 83 in the two side wheel extrusion units 8 are combined with the door sill edge position. The two side pulleys 83 can slide on both sides of the rubber strip when or after the rubber strip is installed, and are used to assist the tooling extrusion wheel 6 in working, thereby avoiding the rubber strip from slipping and improving the installation efficiency of the rubber strip.

[0043] As a preferred embodiment, a first mounting block 91 and a second mounting block 92 are fixedly arranged in the second mounting cavity 21. The first mounting block 91 and the second mounting block 92 are used to install the drive assembly 7. The first mounting block 91 and the second mounting block 92 provide a stable support platform for the drive assembly 7, ensuring the stability and reliability of the drive assembly 7 during operation.

[0044] As a preferred embodiment, Figure 3 、 Figure 4 and Figure 5 As shown, the drive assembly 7 includes a rotating wheel 71, a cam 72, a cam rod 74, and a drive unit 73. The cam rod 74 is rotatably connected between the first mounting block 91 and the second mounting block 92. The cam 72 is coaxially fixed to the cam rod 74. The cam 72 contacts the rotating wheel 71. The drive unit 73 is used to drive the cam rod 74 to rotate. Specifically, the drive unit 73 includes a transmission shaft 731 rotatably connected to the second mounting block 92 and a motor 732 fixed to the second mounting block 92. A first bevel gear 733 is coaxially provided at the end of the transmission shaft 731, and a driven gear 734 is coaxially fixed to the transmission shaft 731.

[0045] The output shaft of the motor 732 is coaxially connected to a driving gear 735 , which meshes with the driven gear 734 ; one end of the cam rod 74 is coaxially connected to a second bevel gear 736 , which meshes with the first bevel gear 733 and the second bevel gear 736 .

[0046] According to the above technical solution, when the motor 732 starts working, the output shaft drives the driving gear 735 to rotate. Since the driving gear 735 is engaged with the driven gear 734, the power from the motor 732 is transmitted to the driven gear 734 and the transmission shaft 731, and the transmission shaft 731 rotates accordingly, driving the cam rod 74 to rotate through the first bevel gear 733 and the second bevel gear 736. As the cam rod 74 rotates, the cam 72 also rotates accordingly. The contour shape of the cam 72 enables it to generate a force that pushes the rotating wheel 71 when it contacts the rotating wheel 71, and the force is transmitted to the slide rod 5 through the rotating wheel 71. After receiving the driving force from the rotating wheel 71, the slide rod 5 begins to slide to the left along the axial direction of the first mounting cavity 11.

[0047] In a possible implementation, the driving unit 73 may be directly in the form of a motor 732 , which is connected to the cam rod 74 via an output shaft of the motor 732 to drive the rotation of the cam 72 .

[0048] As a preferred embodiment, Figure 3 As shown, the slide rod 5 includes a rod body 51, a ring 52 and a connecting head 53. The ring 52 is coaxially fixed on the rod body 51, the connecting head 53 is fixedly set at the right end of the rod body 51, the left end of the rod body 51 is connected to the tooling extrusion wheel 6, and the rotating wheel 71 is rotatably installed on the connecting head 53.

[0049] Furthermore, an elastic member 10 is provided in the first installation cavity 11, the left end of the elastic member 10 is connected to the inner wall of the first body 1, and the right end of the elastic member 10 is connected to the ring 52. The elastic member 10 has a tendency to drive the ring 52 closer to the second body 2 (that is, in Figure 3 In the embodiment, the elastic member 10 has a tendency to drive the ring 52 and the rod body 51 to move to the right); in this embodiment, the elastic member 10 is preferably a spring. When the cam 72 rotates, it can drive the slide bar 5 to slide along the axis of the first installation cavity 11, thereby driving the tooling extrusion wheel 6 to approach the door rubber strip. When the tooling extrusion wheel 6 contacts the door rubber strip, it begins to extrude and install it; at this time, the elastic member 10 plays a buffering and resetting role in this process. When the thrust of the cam 72 on the rotating wheel 71 decreases, the elastic member 10 will drive the ring 52 and the rod body 51 to reset to the right, so that the tooling extrusion wheel 6 returns to its initial position. As the cam 72 continues to rotate, the slide bar 5 and the tooling extrusion wheel 6 will continuously reciprocate. The tooling extrusion wheel 6 will knock and squeeze the door rubber strip to ensure that the rubber strip can be evenly installed in the installation groove of the door frame.

[0050] Furthermore, the axis of the auxiliary wheel 4 is perpendicular to the axis of the tooling extrusion wheel 6 and the side pulley 83, wherein the auxiliary wheel 4 and the side pulley 83 are made of metal material, thereby ensuring that the device can still have a long service life even under frequent stress during use.

[0051] As a preferred embodiment, a control switch 101 is provided on the second body 2 , and the control switch 101 is control-connected to the motor 732 for starting or stopping the motor 732 .

[0052] When installing the rubber strip, place the rubber strip near the installation groove of the door frame. The operator uses his hands or other tools to initially embed one end of the door rubber strip into the installation groove of the door frame. At this time, the auxiliary wheel 4 on the first body 1 plays an auxiliary role. The auxiliary wheel 4 can roll along the door frame to help initially position the door rubber strip, making it easier for the tooling extrusion wheel 6 to further squeeze and install it. After the door rubber strip is initially positioned, the control switch 101 is started, and the drive component 7 works to drive the slide bar 5 to move. Under the action of the elastic member 10, the tooling extrusion wheel 6 moves back and forth to squeeze the door rubber strip along the installation groove of the door frame. To ensure that the rubber strip can be completely squeezed into the installation groove of the car door, when the tooling extrusion wheel 6 has completely passed along the car door frame, the drive component 7 can be turned off to stop the movement of the tooling extrusion wheel 6; the auxiliary wheel 4 or the side pulley 83 can also be used to slide and squeeze the rubber strip again to ensure that the rubber strip is assembled within the standard range according to the process requirements; after the rubber strip is installed, check the installation of the rubber strip to ensure that there is no omission or misplacement; this device has a simple structure, strong practicality, and can be used repeatedly. It is suitable for rubber strip installation operations in various positions such as front doors, rear doors, and back doors, which improves the installation efficiency of the rubber strip and reduces the work intensity.

[0053] The above embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Any equivalent substitution or modification made by those skilled in the art based on the present invention shall fall within the protection scope of the present invention.
