Description

Technical Field

[0001] This utility model belongs to the field of automotive processing technology, specifically relating to a multi-vehicle tooling switching system. Background Technology

[0002] As living standards improve, customers have higher demands for cars, leading to a faster pace of model updates and replacements. For car manufacturers, equipping each model with a separate production line would inevitably increase costs significantly, hindering market competitiveness. Therefore, cross-line production of multiple models is particularly important.

[0003] When different automotive parts need to be produced on the same production line, the tooling changeover at the same workstation needs to be considered. Traditional changeover solutions mainly use rotary table-type changeovers. While this method can switch between tooling for multiple vehicle models, its overall structure is complex and requires a significant amount of space. Furthermore, this method can only handle the changeover of tooling for 3-5 vehicle models, making it difficult to meet the requirements for changing tooling for more models, thus presenting certain limitations. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a multi-vehicle tooling switching system that can realize the switching needs of tooling for multiple vehicle models at low cost.

[0005] To achieve the above and other related objectives, this utility model provides a multi-vehicle tooling switching system, including a tooling support and positioning device and a tooling transfer trolley that docks with the tooling support and positioning device. The tooling support and positioning device includes a support frame and a first guide mechanism, a first rolling support platform, and a tooling positioning mechanism located on the support frame. There are two first guide mechanisms, which are spaced apart on the support frame in a left-right direction. The first rolling support platform is located between the two first guide mechanisms, and the tooling positioning mechanism includes a tooling positioning pin and a driving component for extending and retracting the tooling positioning pin. The tooling transfer trolley includes a frame and wheels located below the frame. The frame is provided with two second guide mechanisms and a second rolling support platform located between the two second guide mechanisms. When the frame docks with the support frame, the two second guide mechanisms are respectively located on the extension lines of the two first guide mechanisms.

[0006] Preferably, both the first guiding mechanism and the second guiding mechanism include a guide wheel mounting component and a plurality of guide wheels spaced apart along the front-rear direction of the guide wheel mounting component.

[0007] Preferably, the guide wheel mounting component of the first guide mechanism is fixed to the support frame by bolts, and the guide wheel mounting component of the second guide mechanism is fixed to the vehicle frame by bolts; the guide wheel mounting component is provided with a plurality of first adjustment holes extending in the left and right direction, and the support frame and the vehicle frame are provided with first bolt holes corresponding to the first adjustment holes one by one; the bolt shank of the bolt passes through the first adjustment hole and is threadedly connected to the corresponding first bolt hole.

[0008] Preferably, the first rolling support platform is an air-floating ball bearing platform.

[0009] Preferably, the support frame is provided with a rear limiting mechanism and / or a positioning detection sensor.

[0010] Preferably, the support frame is provided with a vehicle model recognition device for acquiring vehicle model information on the tooling.

[0011] Preferably, the vehicle model recognition device is a camera or a video camera.

[0012] Preferably, the vehicle frame and the support frame are connected by a front and rear docking mechanism; the front and rear docking mechanism includes a first docking member disposed on the vehicle frame, a second docking member disposed on the support frame, and an intermediate connecting member for connecting the first docking member and the second docking member.

[0013] Preferably, the front end of the support frame is provided with two guides, which cooperate to adjust the docking position of the vehicle frame.

[0014] Preferably, the bottom of the support frame is provided with multiple leveling pillars.

[0015] As described above, the multi-vehicle tooling switching system of this utility model has the following beneficial effects:

[0016] This invention employs a tooling transfer trolley that can dock with a tooling support and positioning device to switch between tooling for different vehicle models. Compared to traditional turntable switching solutions, this invention's multi-vehicle tooling switching system not only reduces space requirements but also meets the switching needs of tooling for any vehicle model, making it more widely applicable. Furthermore, the tooling support and positioning device and the tooling transfer trolley are equipped with matching guide mechanisms in the front-to-back direction, and utilize a rolling support platform to support the tooling, ensuring that the tooling only requires a small thrust to switch between the tooling support and positioning device and the tooling transfer trolley, effectively reducing manpower output and offering advantages in time and labor saving.

Detailed Implementation

[0027] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0028] Please see Figures 1 to 8It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the disclosed technical content. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0029] like Figure 1 As shown. This application provides a multi-vehicle tooling switching system, which includes a tooling support and positioning device 1 and a tooling transfer trolley 2 that can dock with the tooling support and positioning device 1 to switch tooling for different vehicle models, so as to meet the tooling switching needs of different vehicle models at low cost.

[0030] For ease of description, in the following embodiments, the directions are defined as follows: the length direction of the tooling support and positioning device 1 is defined as the front-to-back direction, the width direction of the tooling support and positioning device 1 is defined as the left-to-right direction, and the height direction of the tooling support and positioning device 1 is defined as the up-down direction; based on this, in Figure 1 In the view shown, the X direction is the front-to-back direction, the Y direction is the left-to-right direction, and the Z direction is the up-to-down direction.

[0031] like Figure 1 , Figure 2 and Figure 6 As shown, the tooling support and positioning device 1 involved in this application includes a support frame 11 and a first guide mechanism 12a, a first rolling support platform 13a, and a tooling positioning mechanism 14 located on the support frame 11. There are two first guide mechanisms 12a, which are spaced apart on the support frame 11 in the left-right direction to form a first channel for the tooling to pass through. The first rolling support platform 13a is located between the two first guide mechanisms 12a and is used to provide rolling support for the tooling in the first channel, thereby reducing the frictional force of the tooling moving within the first channel. The tooling positioning mechanism 14 includes a tooling positioning pin 141 and a driving component 142 that drives the tooling positioning pin 141 to extend and retract. The driving component 142 can be a cylinder or an electric push rod, or various other telescopic driving components. The locking and unlocking of the tooling on the tooling support and positioning device 1 are achieved by extending and retracting the tooling positioning pin 141.

[0032] like Figure 1 and Figure 2As shown, the tooling transfer trolley 2 involved in this application includes a frame 21 and traveling wheels 22 located below the frame 21. The traveling wheels 22 are preferably casters with brakes. The rear end of the frame 21 can be connected to the front end of the support frame 11 in the front-rear direction to form an integral structure. The frame 21 is provided with two second guide mechanisms 12b and a second rolling support platform 13b located between the two second guide mechanisms 12b. When the frame 21 is connected to the support frame 11 in the front-rear direction, the two second guide mechanisms 12b are respectively located on the extension lines of the two first guide mechanisms 12a, so that the second channel formed between the two second guide mechanisms 12b can be connected to the first channel on the tooling support positioning device 1 to form a straight channel of equal width.

[0033] It should be noted that each guiding mechanism includes a guide plate and / or a guide wheel assembly, which is not limited; in this embodiment, in order to reduce the friction of tooling movement, each guiding mechanism is composed of a guide wheel assembly.

[0034] Specifically, such as Figure 5 As shown, the guide wheel assembly includes a guide wheel mounting member 121 and a plurality of guide wheels 122 that are rotatably disposed on the guide wheel mounting member 121 at intervals in the front-rear direction.

[0035] Since the width of tooling may vary for different vehicle models, in order to adapt to the movement requirements of tooling with different widths, the guide wheel mounting component 121 on the support frame 11 and the frame 21 needs to have a front and rear position adjustment function. The front and rear position adjustment method of the guide wheel mounting component 121 can be automatic adjustment (such as adjustment by telescopic structure such as cylinder, electric push rod, etc.) or manual adjustment, which is not limited. Based on cost considerations, the guide wheel mounting component 121 in this embodiment adopts a manual adjustment method for front and rear position adjustment.

[0036] In a preferred embodiment, such as... Figures 1 to 5 As shown, the guide wheel mounting component 121 of the first guide mechanism 12a is fixed to the support frame 11 by bolts, and the guide wheel mounting component 121 of the second guide mechanism 12b is fixed to the frame 21 by bolts. The guide wheel mounting component 121 is provided with a plurality of first adjustment holes 1211 extending in the left and right direction. The support frame 11 and the frame 21 are provided with first bolt holes corresponding to the first adjustment holes 1211. The first adjustment holes 1211 only allow the bolt shank to pass through (i.e., the width of the first adjustment hole 1211 is greater than the diameter of the bolt shank but less than the diameter of the bolt head). Thus, when the bolt shank passes through the first adjustment hole 1211 and is threaded into the corresponding first bolt hole, the guide wheel mounting component 121 can be relatively fixed to the support frame 11 or the frame 21. When it is necessary to adjust the front and rear position of the guide wheel mounting component 121, simply loosen the bolts, and then adjust the front and rear position of the guide wheel mounting component 121 as needed before tightening the bolts again.

[0037] It should be noted that in the above-mentioned multi-vehicle tooling switching system, the rolling elements of each rolling support platform are either rollers or balls, and there is no limitation on this; in this embodiment, the rolling elements of each rolling support platform are balls.

[0038] In a preferred embodiment, the first rolling support platform 13a is an air-floating ball platform, and the second rolling support platform 13b is a conventional ball platform. In this way, when the tooling moves on the first rolling support platform 13a, the balls only experience rolling friction with the tooling, thereby improving the service life of the balls.

[0039] like Figure 3 As shown, the support frame 11 is equipped with a rear limit mechanism 15 and / or a positioning detection sensor to ensure that the tooling can move accurately to the positioning position and avoid excessive or insufficient movement.

[0040] like Figure 1 As shown, the support frame 11 is equipped with a vehicle identification device 16 for acquiring vehicle information on the tooling. The vehicle identification device 16 includes, but is not limited to, a camera, a barcode scanner, etc. The specific structure used depends on how the vehicle information is set on the tooling (e.g., when the vehicle information is set in the form of a barcode or QR code, the vehicle identification device 16 is a barcode scanner).

[0041] In a preferred embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, the frame 21 and the support frame 11 are connected by a front and rear docking mechanism. The front and rear docking mechanism includes a first docking member 31 on the frame 21, a second docking member 32 on the support frame 11, and an intermediate connecting member 33 for connecting the first docking member 31 and the second docking member 32. Thus, when the frame 21 and the support frame 11 are docked in place, the intermediate connecting member 33 can be used to lock the positions of the first docking member 31 and the second docking member 32, thereby connecting the tooling support positioning device 1 and the tooling transfer trolley 2 into one unit. The intermediate connecting member can be a bolt or a pin, which is not limited. For convenience, the intermediate connecting member is preferably a pin.

[0042] Understandably, in order to prevent the pin from being lost, positioning holes for inserting the pin can be provided in the empty area of ​​the frame 21.

[0043] In an optional embodiment, the rear end of the frame 21 is provided with a first positioning member 41, and the front end of the support frame 11 is provided with a second positioning member 42 that is inserted and engaged with the first positioning member 41; the insertion and engagement of the first positioning member 41 and the second positioning member 42 ensures the docking accuracy between the frame 21 and the support frame 11.

[0044] In an alternative embodiment, such as Figure 1 , Figure 2 and Figure 8 As shown, the front end of the support frame 11 is provided with two guides 17, which work together to adjust the docking position of the frame 21.

[0045] Specifically, such as Figure 8 As shown, the guide 17 includes a straight guide portion 171 and an inclined guide portion 172 located at the front end of the straight guide portion 171; the distance between the two straight guide portions 171 is adapted to the width of the frame 21, and the two inclined guide portions 172 form a guide opening that is smaller at the rear and larger at the front, so as to use the guide opening to correct the position of the frame 21 and ensure that the frame 21 can smoothly enter between the two straight guide portions 171 and dock with the support frame 11.

[0046] like Figure 4 As shown, in order to facilitate the movement of the tooling transfer trolley 2, a handrail is provided on the frame 21, including a first handrail 23a located at the front end of the frame 21.

[0047] Furthermore, a second handrail 23b is provided at the middle and rear of the frame 21.

[0048] like Figure 1 As shown, the bottom of the support frame 11 is provided with multiple leveling pillars 18; the leveling pillars 18 can be any existing pillars that can achieve height adjustment, and there is no limitation on them.

[0049] The multi-model tooling switching system is used as follows: An idle tooling transfer trolley 2 is docked onto the tooling support and positioning device 1; the positioning pin 141 on the tooling support and positioning device 1 is retracted to release the lock on tooling A on the tooling support and positioning device 1; the first rolling support platform 13a is activated, causing the ball bearings to lift; tooling A is pushed onto the tooling transfer trolley 2 and removed by the tooling transfer trolley 2; the tooling transfer trolley 2 carrying tooling B is docked onto the tooling support and positioning device 1, and tooling B is pushed onto the tooling support and positioning device 1 to reach a preset position; the model identification device 16 acquires the model information on tooling B and extends the positioning pin 141; the ball bearings of the first rolling support platform 13a descend, completing the positioning of tooling B; the idle tooling transfer trolley 2 is then pulled away to complete the tooling switching; the entire switching process is time-saving and labor-saving, can meet the switching needs of tooling for various models, and has value for widespread application.

[0050] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
