Description

Technical Field

[0001] The utility model relates to the field of automobile exterior decoration, and more specifically to an assembly tooling for a flexible multi-functional bumper integrated component. Background Art

[0002] As an indispensable part of an automobile, the bumper has many functions and roles: From the perspective of safety, when a low-speed collision accident occurs to the automobile, the bumper can play a buffering role to protect the front and rear vehicle bodies; when colliding with a pedestrian, it can play a certain role in protecting the pedestrian. From the perspective of appearance, the bumper is an important component for decorating the appearance of the automobile. At the same time, the bumper also has a certain aerodynamic effect, which can improve the performance of the automobile.

[0003] Under normal circumstances, each type of bumper is separately equipped with an assembly jig tooling to complete the assembly. However, with the increasing demand for personalized customization of automobiles, and the continuous acceleration of the automobile replacement cycle by manufacturers to improve product competitiveness, especially in the current era of coexistence of electric and fuel vehicles, the same vehicle model often has multiple versions (fuel version, pure electric version, hybrid version, sports version), resulting in a large variety of bumpers, many configurations, and fast updates. If the previous mode is still adopted, that is, each type of bumper is separately equipped with an assembly jig tooling, it will result in a large number of jig toolings, thus bringing various problems: First, the cost of manufacturing the jig increases; Second, a large number of jig toolings need to be placed on the assembly line with limited space, which poses a great challenge to the factory layout; Third, the bumpers are updated frequently, and it is difficult to transform the old jig toolings to be suitable for new products, resulting in waste of resources; Fourth, too many jig toolings occupy the space of the material rack, resulting in an increase in the distance for picking and placing parts, thus affecting the beat. For the jig toolings with less frequent use, they occupy valuable assembly line space, resulting in low utilization rate of the assembly line space; Fifth, the jig toolings occupy too much assembly line space, affecting the operating space of the operator, increasing the risk of bumping the tooling and the material rack during the handling process of the bumper product, and affecting the qualified rate and appearance quality of the bumper product.

[0004] To solve the above problems, currently, the sharing of jig toolings can be achieved through a lifting jig. However, the lifting jig still has great limitations: First, the lifting jig can only achieve the sharing of two types of bumper products, and requires that the bumper products to be shared have similar shapes; Second, the overlapping surface of the two bumper products cannot take into account the effective support for the two products; Finally, due to the use of a lifting mechanism, it is relatively difficult to transform it into a jig suitable for new products. Summary of the Utility Model

[0005] To solve the problems in the above-mentioned prior art, the utility model provides an assembly tooling for a flexible multi-functional bumper integrated component, which can achieve the sharing and effective support of multiple bumper products, does not require the similar shapes of the bumper products to be shared, and has strong transformability.

[0006] A flexible multi-functional bumper integrated component assembly tool provided by the present utility model comprises: a rotation switching mechanism, which is arranged above the general framework through two spaced-apart mounting plates. The rotation switching mechanism comprises a plurality of rotation units, and each rotation unit comprises a rotation shaft. The two ends of the rotation shaft respectively penetrate through the mounting plates and are rotatably connected to the mounting plates. Four mounting surfaces are annularly arranged on the circumference of the rotation shaft between the mounting plates, and simulation blocks corresponding to different bumper products are detachably mounted on each mounting surface.

[0007] Further, a drive shaft is mounted on one of the mounting plates. The rotation shafts of two adjacent rotation units among the plurality of rotation units are connected by a chain transmission mechanism, and the rotation shaft of one rotation unit among the plurality of rotation units is connected to the drive shaft.

[0008] Further, the drive shaft is connected to a drive device.

[0009] Further, the drive device is a handle or a rotary cylinder or a servo motor.

[0010] Further, a tensioning wheel is provided in the chain transmission mechanism.

[0011] Further, the included angle between two adjacent mounting surfaces among the four mounting surfaces is 90°.

[0012] Further, a groove is formed at a position on the positioning plate corresponding to the locking block.

[0013] Further, the cylinder is mounted on the general framework and is connected to the positioning plate through a connecting member.

[0014] Further, a plurality of fixed support blocks are provided on the general framework.

[0015] Further, four universal wheels are provided below the general framework.

[0016] The present utility model can simultaneously meet the assembly requirements of four products, can save site resources and increase the site utilization rate. The present utility model adapts to different products by switching different mounting surfaces, has relatively low requirements for the external shapes of shared products, and is not affected by the coincident surfaces of shared products. In addition, the simulation blocks of the present utility model are detachable and have strong modifiability. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following combines the accompanying drawings to give the preferred embodiments of the present utility model and describes them in detail.

[0021] As Figure 1 shown, the assembly tooling for the flexible multi-functional bumper integrated part of the present utility model includes a general framework 1, two spaced-apart mounting plates 2, and a rotation and switching mechanism 3. Among them, the rotation and switching mechanism 3 is erected above the general framework 1 through the mounting plates 2. A driving shaft 4 is installed on one of the mounting plates 2. The driving shaft 4 is connected to the rotation and switching mechanism 3 and can be externally connected to a driving device (not shown in the figure), so that when the driving device drives the driving shaft 4 to rotate, the driving shaft 4 can drive the rotation and switching mechanism 3 to rotate. The driving device can be a handle, or a rotary cylinder or a servo motor, so that the driving shaft 4 can rotate manually or automatically.

[0022] Combined with Figure 2 , the rotation and switching mechanism 3 includes a plurality of rotation units 31 for carrying bumper products. Each rotation unit 31 includes a rotation shaft 311. The two ends of the rotation shaft 311 respectively penetrate through the two mounting plates 2 and are rotatably connected to the two mounting plates 2. Four mounting surfaces are annularly arranged on the circumference of the rotation shaft 311 between the mounting plates 2. The adjacent two mounting surfaces among the four mounting surfaces form a 90° angle, and simulation blocks corresponding to different bumper products are detachably installed on each mounting surface. For example, assuming that the four mounting surfaces of each rotation shaft are surface A, surface B, surface C, and surface D respectively, then the simulation blocks corresponding to type A bumper products are provided on the A surfaces of all rotation shafts, the simulation blocks corresponding to type B bumper products are provided on the B surfaces of all rotation shafts, the simulation blocks corresponding to type C bumper products are provided on the C surfaces of all rotation shafts, and the simulation blocks corresponding to type D bumper products are provided on the D surfaces of all rotation shafts. In this way, the rotation and switching mechanism 3 can simultaneously meet the usage needs of four bumper products. When a new bumper product appears, the simulation blocks on the mounting surface can be replaced. It should be noted that the number of rotation units 31 can be adjusted according to the shapes and structures of different bumper products. Since each mounting surface corresponds to one bumper product and the simulation block is shaped accordingly with the corresponding bumper product, if the bumper product placed during assembly does not match the mounting surface, the bumper product cannot fit the mounting surface and is in a suspended and shaking state on the assembly tooling. In this way, the present utility model has an anti-misoperation recognition function, which can prevent the assembly from being incomplete and wasting the beat due to the use of the wrong mounting surface.

[0023] To achieve the rotational switching of the above four mounting surfaces, the rotating shafts 311 of adjacent two rotating units 31 are connected by a chain drive mechanism 32, and the rotating shaft 311 of one of the rotating units 31 is connected to the driving shaft 4. When the driving shaft 4 rotates by a certain angle, it drives the rotating shaft 311 connected to it to rotate, and then makes the other rotating shafts 311 rotate synchronously. A tensioning wheel 33 is provided in the chain drive mechanism 32, which can be used to adjust and control the tension of the chain. Therefore, in addition to synchronous rotation, the independent rotation of each rotating shaft 311 can also be achieved by adjusting the tensioning wheel.

[0024] When the rotation switching mechanism 3 rotates in place, that is, when the simulation blocks on the mounting surfaces facing upward of each rotating shaft 311 correspond to the bumper products to be assembled, each rotating unit 31 needs to be locked and fixed. Therefore, the present invention further includes a positioning and locking structure 5.

[0025] As Figure 3 shown, the positioning and locking structure 5 includes a locking block 51, a positioning plate 52 for clamping the locking block 51, and a cylinder 53 for driving the lifting of the positioning plate 52. Among them, the locking block 51 is fixedly connected to one end of the rotating shaft 311 and rotates with the rotation of the rotating shaft 311. A groove 54 is formed at the position corresponding to the locking block 51 on the positioning plate 52. When the positioning plate 52 moves upward, the locking block 51 can be clamped in the groove 54, so that the rotating unit 31 is locked and fixed; when the positioning plate 52 moves downward, the locking block 51 can be separated from the groove 54, so that the rotating unit 31 is unlocked. The cylinder 53 is installed on the general frame 1 and is connected to the positioning plate 52 through a connecting member 55. When the cylinder 53 makes a lifting movement, it pushes the connecting member 55 to move up and down, thereby driving the positioning plate 52 to move up and down.

[0026] In addition, a plurality of fixed support blocks 6 can be provided on the general frame 1 to make the entire assembly tooling more stable. Four universal wheels 7 can also be provided below the general frame 1 to enable the assembly tooling of the present invention to be moved conveniently and quickly.

[0027] The following describes the use process of the flexible multi-functional bumper integrated part assembly tooling of the present invention.

[0028] First, according to the bumper product to be assembled, determine the mounting surface (surface A or surface B or surface C or surface D) facing upward to which the rotating unit 31 should be adjusted.

[0029] Secondly, the cylinder 53 drives the positioning plate 52 to move downward to unlock the rotating unit 31.

[0030] Next, rotate the drive shaft 4 to synchronously rotate all the rotating shafts 311. When the rotating unit 31 is basically rotated in place, stop the rotation of the drive shaft 4. At this time, the individual rotating shaft 311 can be rotated by adjusting the chain drive mechanism 32 so that each rotating unit 31 is in the optimal position.

[0031] Then, the cylinder 53 drives the positioning plate 52 to move upward, so that the locking block 51 is clamped in the groove 54, thereby locking and fixing the rotating unit 31. At this time, the switching is completed, and the assembly tooling can be used for the assembly of the bumper product. After the assembly is completed, remove the assembled product. If subsequent products need to be switched, repeat the above steps for switching.

[0032] The flexible multi-functional bumper integrated part assembly tooling of the present utility model has the following advantages:

[0033] 1) Wide applicability: It can simultaneously meet the assembly of four products. When in use, different installation surfaces are switched to adapt to different products, with relatively low requirements for the outer shapes of the shared products and not being affected by the coincidence surfaces of the two shared products.

[0034] 2) Strong transformability: In case of the replacement of new and old products, only the simulation blocks corresponding to the discontinued projects need to be removed and replaced with the simulation blocks corresponding to the new project products, without the need to re-develop new assembly tooling.

[0035] 3) Fast switching: The four installation surfaces corresponding to the four products can achieve fast switching. The manual switching time is about 5 seconds, and the automatic switching time is about 2 seconds.

[0036] 4) High safety: Protective covers can be installed on the chain drive mechanism and the positioning and locking mechanism to increase the protection of the operator during use and improve the safety of equipment use.

[0037] 5) Cost savings: Traditional tire molds generally only meet the assembly of one or two product bumper integrated parts. The present utility model can simultaneously meet the assembly of four products, saving about 50%, or even 75% of the site resources, increasing the site utilization rate, and effectively saving the production site of the assembly line and the manufacturing cost and development cycle of the assembly tire mold.

[0038] The above-mentioned are only the preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various changes can be made to the above embodiments of the present utility model. That is, all simple, equivalent changes and modifications made according to the claims and the content of the specification of the present utility model application fall within the scope of the protection of the claims of the present utility model patent. The content not described in detail in the present utility model is all conventional technical content.
