Description

Technical Field

[0001] This invention belongs to the field of engineering machinery technology, specifically relating to a tooling and working method for assembling visible seams in vehicle side windows. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] The assembly of side windows in buses is an important indicator for evaluating the vehicle's appearance performance. As passengers' requirements for the riding experience increase, the market demand for more efficient, durable, and aesthetically pleasing side window assembly solutions is gradually increasing. The cleanliness and quality of the vehicle's interior and exterior are also part of the overall passenger experience. How to ensure the accuracy, sealing, and long-term stability of side window assembly while maintaining the overall vehicle production efficiency has become an urgent technical challenge to be solved.

[0004] In the existing technology, the common process for assembling bus side windows is to directly apply sealant to the joints of the side window glass. In order to improve the aesthetics of the side window glass, each side window glass needs to be adjusted one by one. Due to the large number of windows in a bus, the assembly efficiency is low. The direct sealant application process is prone to problems such as rough surface of the sealant joint or discoloration, cracking, water leakage, and increased noise after long-term use, which affects the overall aesthetics of the vehicle and directly affects the physical comfort of the passengers. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides a tooling and method for assembling visible seams in vehicle side windows. Through multiple adjustment components, the efficiency of side window assembly and the application range of the tooling are improved. By using the tooling to align the seams and simultaneously inject adhesive into the interlayer between the side window glass and the window pillar, the external adhesive seam scraping process is reduced, the sealing performance is enhanced, the aesthetics of the vehicle's appearance are improved, and the aging rate of the sealant is reduced.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0007] In a first aspect, the present invention provides a tooling for assembling visible seams on vehicle side windows, comprising a negative pressure positioning component, a positioning connecting rod, and a plane adjustment component; there are two negative pressure positioning components, each of which is provided with a movable positioning sleeve, and the negative pressure positioning components are slidably connected to both ends of the positioning connecting rod through the movable positioning sleeve; the positioning connecting rod is uniformly provided with a plurality of through holes;

[0008] The planar adjustment assembly includes a clamping guide rail, an upper nut, a lower nut, a rubber pad, a planar adjustment nut, and a planar adjustment rod. The clamping guide rail is installed in the through hole. The upper nut and the lower nut are both installed on the clamping guide rail. The upper nut is positioned above the positioning connecting rod, and the lower nut is positioned below the positioning connecting rod. The planar adjustment rod passes through the clamping guide rail and is coaxially arranged with the clamping guide rail. The planar adjustment rod is threaded into the planar adjustment nut. The planar adjustment nut is located at the upper end of the clamping guide rail, and a correction pull rod is provided at the lower end of the planar adjustment rod.

[0009] Furthermore, the negative pressure positioning assembly also includes a locking bolt, a negative pressure suction cup, and a suction cup mounting base; the upper end face of the movable positioning sleeve is provided with a locking positioning hole, and the locking positioning hole is provided with a thread for installing the locking bolt; the lower end face of the movable positioning sleeve is provided with a suction cup mounting base, and a negative pressure suction cup is installed on the suction cup mounting base; the suction cup mounting base and the negative pressure suction cup are connected by studs.

[0010] Furthermore, the through hole is shaped like a waist hole, allowing the clamping guide rail to slide within the through hole.

[0011] Furthermore, a plurality of planar adjustment components are provided, and the number of planar adjustment components is at most the same as the number of through holes.

[0012] Furthermore, the outer side of the clamping guide rail is provided with threads for installing the upper nut and the lower nut, and the length of the threads on the outer side of the clamping guide rail is the same as the length of the clamping guide rail.

[0013] Furthermore, a groove is provided on the side of the reference base away from the clamping guide rail, and a rubber pad is provided in the groove.

[0014] Furthermore, a handle is provided at the upper end of the planar adjustment rod, and a quadrangular prism is provided at the upper end of the planar adjustment rod. A square hole is provided at the center of the handle. The quadrangular prism cooperates with the square hole to realize the transmission between the planar adjustment rod and the handle.

[0015] Secondly, the present invention also provides a working method for a tooling for assembling visible seams on vehicle side windows, comprising the following steps:

[0016] S1. Fixing the tooling: Pre-attach the side window glass to the side window frame of the vehicle body, fix the two negative pressure positioning components on the body skin plane at the location of the side window, and assemble the positioning connecting rod to the negative pressure suction cup positioning component by tightening the bolts.

[0017] S2. Adjustment of the side window glass: The position between the clamping guide rail and the positioning connecting rod is controlled by the upper nut and the lower nut. The reference seat is adjusted to the required adjustment position of the side window glass along with the clamping guide rail, thereby determining the adjustment position of the side window glass. The plane adjustment rod is rotated.

[0018] The correction tie rod adjusts the side window to the plane of the reference seat under the action of the plane tie rod, and the side window is glued to the side window frame of the vehicle body using adhesive; the other plane adjustment components are adjusted respectively.

[0019] Furthermore, in S1, one of the negative pressure positioning components is inserted into one end of the positioning connecting rod, and the other positioning connecting rod is inserted into the other end of the positioning connecting rod. One of the negative pressure positioning components is fixed to the upper edge of the side window frame of the vehicle side window, and the other negative pressure positioning component is fixed to the lower edge of the side window frame of the vehicle side window.

[0020] Furthermore, the guide rail is clamped by controlling the lower nut or upper nut of the guide rail, so that the clamping guide rail moves vertically up and down through the guide groove on the positioning connecting rod;

[0021] Using the handle at the upper end of the plane adjustment rod, rotate the correction rod at the lower end of the plane adjustment rod to match the gap between the two side window glass panes. Insert the lower end of the plane adjustment rod along the side window butt joint into the space between the glass and the side window frame of the vehicle body, and rotate it 90° to abut against the inner surface of the two side window glass panes. By tightening the plane adjustment nut and cooperating with the lower end of the clamping guide rail, the front and rear side window glass panes are planely limited and fixed.

[0022] Compared with the prior art, the advantages and positive effects of this invention are:

[0023] The negative pressure positioning component of this invention is slidably connected to the positioning connecting rod via a movable positioning sleeve, and has locking bolts to fix the relative positions. The negative pressure suction cup can fix the fixture to the bus side window glass for precise positioning. At the same time, the movable positioning sleeve and suction cup are replaceable to avoid the problem of inaccurate positioning of the fixture. The adjustment position of the side window glass is determined by controlling the position of the clamping guide rail with a nut, and the side window glass is fixed by plane limit using a plane adjustment rod and a correction tie rod, realizing a glue-free assembly process for the side window. This can effectively control the flatness of the left and right side windows of the bus to be on the same plane, reduce the construction of side window butt joint sealant, and make the side window bonding surface fit tightly with the body window stop installation surface, ensuring the best sealing state and flatness and aesthetics. It overcomes the problems of sealant aging, cracking, unstable performance and high maintenance costs caused by traditional side window assembly that rely on sealant, and realizes side window assembly that does not rely on sealant, is efficient and durable.

[0024] The clamping guide rail of the planar adjustment component of this invention is slidably installed in a through hole shaped like a waist hole. The number of planar adjustment components can be adjusted according to the size of the bus side window, and the distance between the positioning connecting rods can also be adjusted over a wide range. The upper nut and lower nut can adjust the position of the clamping guide rail and the positioning connecting rod, and the reference seat can be adjusted according to whether the bus side window glass is on the same plane, so that the tooling can be applied to different sizes and working conditions.

[0029] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0030] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, unless otherwise expressly indicated by the invention, the singular form is also intended to include the plural form. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0031] This embodiment discloses a tooling for assembling visible seams in vehicle side windows, such as... Figures 1-2As shown, it includes a negative pressure positioning component, a positioning connecting rod 1, and a plane adjustment component; there are two negative pressure positioning components, each with a movable positioning sleeve 11, and the negative pressure positioning components are slidably connected to both ends of the positioning connecting rod 1 through the movable positioning sleeve 11; the positioning connecting rod 1 is evenly provided with a plurality of through holes;

[0032] The planar adjustment assembly includes a clamping guide rail 2, an upper nut 3, a lower nut 4, a rubber pad, a planar adjustment nut 5, and a planar adjustment rod 6. The clamping guide rail 2 is installed in the through hole. The upper nut 3 and the lower nut 4 are both installed on the clamping guide rail 2. The upper nut 3 is arranged above the positioning connecting rod 1, and the lower nut 4 is arranged below the positioning connecting rod 1. The planar adjustment rod 6 passes through the clamping guide rail 2 and is coaxially arranged with the clamping guide rail 2. The planar adjustment rod 6 is threadedly engaged with the planar adjustment nut 5. The planar adjustment nut 5 is arranged at the upper end of the clamping guide rail 2, and a correction pull rod 9 is provided at the lower end of the planar adjustment rod 6.

[0033] The negative pressure positioning assembly also includes a locking bolt 13, a negative pressure suction cup 12, and a suction cup mounting base 10. The upper end face of the movable positioning sleeve 11 is provided with a locking positioning hole, which is threaded for installing the locking bolt 13. When the locking bolt 13 is tightened, the relative position between the movable positioning sleeve 11 and the positioning connecting rod 1 is fixed. When the locking bolt 13 is loosened, relative movement can occur between the movable positioning sleeve 11 and the positioning connecting rod 1. The lower end face of the movable positioning sleeve 11 is provided with a suction cup mounting base 10, on which a negative pressure suction cup 12 is mounted. The negative pressure suction cup 12 can fix the entire fixture to the glass of the bus side window. The suction cup mounting base 10 and the negative pressure suction cup 12 are connected by studs. When the negative pressure suction cup 12 experiences aging or other problems, a new negative pressure suction cup 12 can be promptly replaced to avoid the problem of the entire fixture being unable to be accurately positioned.

[0034] The clamping guide rail 2 is installed in the through hole, which is oblong in shape, allowing the clamping guide rail 2 to slide within the through hole. This enables the fixture to be applied to the correction needs of bus side windows of different sizes. Several plane adjustment components are provided, with the number of components being at most the same as the number of through holes. When the size difference of the bus side window is large, requiring a large span adjustment, and some plane adjustment components need to be removed from the multiple plane adjustment components, the number of plane adjustment components is less than the number of through holes. Simultaneously, the distance between the positioning connecting rods 1 can also be adjusted over a large range to facilitate positioning of the fixture according to the actual size of the bus side window. The upper nut 3 and lower nut 4 are both installed on the clamping guide rail 2. The outer surface of the clamping guide rail 2... The clamping guide 2 has a threaded side for installing the upper nut 3 and the lower nut 4. The length of the thread on the outer side of the clamping guide 2 is the same as the length of the clamping guide 2. The lower end of the clamping guide 2 is provided with a reference seat 8. The side of the reference seat 8 away from the clamping guide 2 is provided with a groove, and a rubber pad 14 is provided in the groove. When all the glass of the bus side window is not on the same plane, the relative position between the clamping guide 2 and the upper nut 3 and the lower nut 4 can be adjusted to make the reference seats 8 on the adjacent clamping guide 2 not in the same plane. When all the glass of the bus side window is on the same plane, the relative position between the clamping guide 2 and the upper nut 3 and the lower nut 4 can be adjusted to make the reference seats 8 on the adjacent clamping guide 2 in the same plane, so that the tooling can be applied to different working conditions.

[0035] Work methods:

[0036] S1. Fixing the tooling: Pre-attach the side window glass 15 to the side window frame 17 of the vehicle body, fix the two negative pressure positioning components to the body skin plane at the position of the side window, insert one of the negative pressure positioning components into one end of the positioning connecting rod 1, insert the other positioning connecting rod 1 into the other end of the positioning connecting rod 1, fix one of the negative pressure positioning components to the upper edge of the side window frame skin of the vehicle body, fix the other negative pressure positioning component to the lower edge of the side window frame 17 skin of the vehicle body, and assemble the positioning connecting rod 1 to the negative pressure suction cup 12 positioning component by tightening the bolt 13.

[0037] S2. Adjustment of the side window glass 15: The position between the clamping guide rail 2 and the positioning connecting rod 1 is controlled by the upper nut 3 and the lower nut 4. The clamping guide rail 2 is controlled by the lower nut 4 or the upper nut 3, so that the clamping guide rail 2 moves vertically up and down through the guide groove on the positioning connecting rod 1. The reference seat 8 is adjusted to the required adjustment position of the side window glass 15 along with the clamping guide rail 2, thereby determining the adjustment position of the side window glass 15 and applying uniform and controllable pressure to the side window glass 15. The plane adjustment rod 6 is rotated, and the correction pull rod 9 at the lower end of the plane adjustment rod 6 is rotated to be the same as the gap between the two side window glass pieces 15 through the upper handle 7. The lower end of the plane adjustment rod 6 is inserted into the gap between the side window glass 15 and the side window frame 17 of the vehicle body along the butt joint of the side window glass 15, and rotated 90° to abut against the inner surface of the two side window glass pieces 15. The front and rear side window glass pieces 15 are fixed in a plane by tightening the plane adjustment nut 5 in cooperation with the lower end of the clamping guide rail 2.

[0038] The correction rod 9 adjusts the side window to the plane of the reference seat 8 under the action of the plane rod, and uses the side window adhesive 16 to bond the side window to the side window frame 17 of the vehicle body; this eliminates the adjustment method of drilling holes and fixing clips on the side window pillars on the outside of the vehicle body, realizing a glue-free assembly process for the side window, and the addition of the device can effectively control the flatness of the left and right side windows of the bus to be on the same plane, reducing the construction of side window joint sealant; the other sets of pressing guide rail 2 components are adjusted respectively to control and press the surface difference of the entire side window according to the technical requirements of the arc or plane, so that the side window bonding surface is tightly attached to the mounting surface of the side window frame 17 of the vehicle body, ensuring the best sealing state and flatness and aesthetics.

[0039] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
