Description

Technical Field

[0001] This utility model relates to the field of automotive assembly technology, and in particular to a top cover crossbeam and top cover positioning assembly fixture. Background Technology

[0002] In the process of automobile assembly, the roof beam, as part of the car frame, is usually one of the first parts to be assembled. The roof is then assembled onto the roof beam by a robotic arm using a special tooling fixture after the roof beam is assembled.

[0003] Since the roof is part of the car's exterior, tooling fixtures usually use suction cups to fix the roof in order to protect its appearance. However, suction cups lack positioning ability when gripping the roof, which often causes the roof to shift slightly, affecting the car assembly process. Utility Model Content

[0004] The purpose of this utility model is to provide a top cover beam and a top cover positioning assembly fixture, which can position the top cover when gripping it, thereby improving the accuracy of gripping.

[0005] This utility model provides a top cover crossbeam and top cover positioning assembly fixture, including:

[0006] The tooling plate and positioning blocks are evenly distributed on the tooling plate and are fixedly assembled on the tooling plate. The top surface of the positioning blocks is flush with the top cover surface.

[0007] Guide rollers, the number of which is twice the number of which are positioning blocks, and each positioning block is provided with guide rollers on both sides. When the top surface of the positioning block is completely in contact with the surface of the top cover, the guide rollers on both sides of the positioning block are in contact with the surface of the top cover.

[0008] The negative pressure component has a first assembly groove formed by hollowing out the center of the positioning block. The negative pressure component is embedded in the first assembly groove and is connected to a negative pressure air source to form negative pressure in the first assembly groove.

[0009] The surface of the negative pressure guide cover in the first assembly slot is completely in contact with the top surface of the positioning block.

[0010] Preferably, the negative pressure assembly includes a rubber sealing ring and a negative pressure vent pipe. The rubber sealing ring is fixedly assembled in the first assembly groove, one end of the negative pressure vent pipe passes through the rubber sealing ring and connects to the inside of the first assembly groove, and the other end of the negative pressure vent pipe is connected to a negative pressure air source.

[0011] Preferably, the top cover beam and the top cover positioning assembly fixture further include a support block and a suction cup assembly. The support block is fixedly mounted on the fixture plate. When the top surface of the positioning block is completely in contact with the top cover surface, the support block is also in contact with the top cover surface at the same time. The center of the support block is hollowed out to form a second assembly groove, and the suction cup assembly is fixedly mounted in the second assembly groove.

[0012] Preferably, the suction cup assembly includes a suction cup vent pipe, a pressure port, and a rubber disc. The suction cup vent pipe is fixedly assembled in the second assembly groove, the pressure port is fixedly connected to the port of the suction cup vent pipe, and the upper surface of the pressure port is flush with the top surface of the support block. The rubber disc is sleeved on the pressure port.

[0013] Preferably, the rubber disc has integrally formed suction cup protrusions evenly distributed along its edge, and the suction cup protrusions are hemispherical.

[0014] Preferably, the number of positioning blocks is four, and the four positioning blocks are arranged in a rectangular shape on the tooling plate.

[0015] Preferably, the positioning block is a nylon block.

[0016] Preferably, the positioning block and the guide roller are both fixed to the tooling plate by screws, and a washer is fitted on the screw. The washer is located between the surface of the tooling plate and the positioning block and the guide roller.

[0017] Preferably, the tooling plate is integrally formed with a material discharge groove.

[0018] Preferably, the tooling plate has an integrally formed assembly hole at its center.

[0019] The technical solution of this utility model uses a positioning block to position the top cover. The gradually curved shape of the top cover prevents the positioning block from fully fitting the top cover when it is not in the planned position, thus leaving a gap. The negative pressure component creates negative pressure at the center of the positioning block. As outside air enters the first assembly groove through the gap, it will drive the top cover to move towards the planned position until the top cover reaches the planned position and is fully in contact with the positioning block. The guide roller will replace the positioning block to abut the top cover before the top cover moves to the planned position, and its own rolling characteristics will help the top cover move more smoothly. Finally, the technical effect of accurately grasping the top cover is achieved. Attached Figure Description

[0030] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] In the description of this utility model, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; 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 utility model based on the specific circumstances.

[0033] Combination Figures 1 to 7 As shown, the top cover beam and top cover positioning assembly tooling provided by this utility model includes a tooling plate 1, a positioning block 2, a guide roller 3, a negative pressure component 4, a support block 5, and a suction cup component 6.

[0034] Combination Figures 1 to 7 As shown, the positioning blocks 2 are evenly distributed on the tooling plate 1. The positioning blocks 2 are fixedly assembled on the tooling plate 1. The top surface of the positioning blocks 2 is flush with the surface of the top cover. All positioning blocks 2 can simultaneously fit against the surface of the top cover. The positioning blocks 2 are made of nylon to avoid damaging the surface of the top cover. The tooling plate 1 is integrally formed with a material removal groove 11 to reduce its own weight. The tooling plate 1 is integrally formed with an assembly hole 12 at the center position, so that it can be precisely fixed and assembled on the robotic arm by bolts.

[0035] In this embodiment, there are four positioning blocks 2, which are arranged in a rectangular pattern on the tooling plate 1 to achieve stable support for the top cover. The number of positioning blocks 2 is not limited to four, and the distribution pattern is not limited to a rectangular distribution. The purpose of stable support for the top cover can be achieved by uniform distribution. For example, three positioning blocks 2 are arranged in a triangular pattern, or five positioning blocks 2 are staggered front and back.

[0036] The number of guide rollers 3 is twice the number of positioning blocks 2. Each positioning block 2 has guide rollers 3 on both sides. When the top surface of the positioning block 2 is completely in contact with the surface of the top cover, the guide rollers 3 on both sides of the positioning block 2 are in contact with the surface of the top cover.

[0037] The center of the positioning block 2 is hollowed out to form a first assembly groove 21. The negative pressure component 4 is embedded in the first assembly groove 21. The negative pressure component 4 is connected to a negative pressure air source and forms a negative pressure in the first assembly groove 21. The negative pressure guides the surface of the top cover and the top surface of the positioning block 2 to fit completely. The negative pressure component 4 includes a rubber sealing ring 41 and a negative pressure vent pipe 42. The rubber sealing ring 41 is fixedly installed in the first assembly groove 21 to ensure the airtightness between the negative pressure vent pipe 42 and the positioning block 2. One end of the negative pressure vent pipe 42 passes through the rubber sealing ring 41 and connects to the inside of the first assembly groove 21. The other end of the negative pressure vent pipe 42 is connected to the negative pressure air source.

[0038] The positioning block 2 and the guide roller 3 are both fixed to the tooling plate 1 by screws 71, and a washer 72 is fitted on the screw 71. The washer is located between the surface of the tooling plate 1 and the positioning block 2 and the guide roller 3. The height of the upper surface of the positioning block 2 and the guide roller 3 can be quickly adjusted by the washer 72, which simplifies the assembly and debugging process.

[0039] In this embodiment, the top cover is positioned by the positioning block 2. The gradually curved shape of the top cover prevents the positioning block 2 from fully fitting the top cover when it comes into contact with an unplanned position, thus leaving a gap. The negative pressure component 4 creates negative pressure at the center of the positioning block 2. As outside air enters the first assembly groove 21 through the gap, it will drive the top cover to move towards the planned position until the top cover reaches the planned position and is fully in contact with the positioning block 2. The guide roller 3 will replace the positioning block 2 to contact the top cover before the top cover moves to the planned position, and use its own rolling characteristics to help the top cover move more smoothly. Finally, the technical effect of accurately grasping the top cover is achieved.

[0040] The support block 5 is also fixedly assembled on the tooling plate 1 by screws 71 and washers 72. When the top surface of the positioning block 2 is completely in contact with the surface of the top cover, the support block 5 is also in contact with the surface of the top cover at the same time, so as to ensure that positioning and fixing are effective at the same time. The center of the support block 5 is hollowed out to form a second assembly groove 51. The suction cup assembly 6 is fixedly assembled in the second assembly groove 51. The suction cup assembly 6 fixes the top cover to the support block 5 by adsorbing it.

[0041] The suction cup assembly 6 includes a suction cup vent pipe 61, a pressure port 62, and a rubber disc 63. The suction cup vent pipe 61 is fixedly assembled in the second assembly groove 51. The pressure port 62 is fixedly connected to the port of the suction cup vent pipe 61, and the upper surface of the pressure port 62 is flush with the top surface of the support block 5. When adsorbing the top cover, the pressure port 62 abuts against the surface of the top cover to provide support and avoid problems such as deformation and leaving marks. The rubber disc 63 is sleeved on the pressure port 62 to improve airtightness. The rubber disc 63 has integrally formed suction cup protrusions 64 evenly distributed along the edge. The suction cup protrusions 64 are hemispherical to prevent the suction cup vent pipe 61 from sticking to the top cover. The suction cup vent pipe 61 can only ensure a stable adsorption effect by working continuously. After the suction cup vent pipe 61 stops working, the suction cup assembly 6 can naturally detach from the surface of the top cover.

[0042] Working process: The positioning assembly fixture is attached to the surface of the top cover under the action of the robotic arm. The negative pressure component 4 is activated first to create negative pressure in the first assembly groove 21. When the top cover is not completely attached to the positioning block 2, the outside air will flow along the gap between the top cover and the positioning block 2 to the first assembly groove 21, thereby driving the top cover to move towards the position where it is completely attached to the positioning block 2.

[0043] like Figure 6 , Figure 7 The diagram shows the situation when the top cover shifts to the left and right sides. When the top cover shifts to the predetermined position, the different curvature shapes at different positions on the top cover create a gap between the top cover and the positioning block 2. Air flows rapidly within the gap, reducing the air pressure inside. The external atmospheric pressure acts on the top cover, causing it to move towards the predetermined position. The guide roller 3 will replace the positioning block 2 in contacting the surface of the top cover before the top cover and positioning block 2 are fully fitted. The guide roller 3 reduces the wear and resistance experienced by the top cover during the movement process by rotating.

[0044] Once the top cover is fully attached to the positioning block 2 and the support block 5, the suction cup assembly 6 is activated, firmly fixing the top cover to the positioning block 2 and the support block 5. At this point, the negative pressure assembly 4 can be stopped.

[0045] Finally, after both the negative pressure component 4 and the suction cup component 6 have stopped working, the top cover can be detached.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
