[0039] It should be noted that the drawings provided in the following embodiments only illustrate the basic concept of the present invention in a schematic manner. Therefore, only the components related to the present invention are shown in the drawings, rather than being drawn according to the number, shape, and size of the components in actual implementation.

[0040] With the increasingly fierce competition in the automobile market, more and more automobile manufacturers adopt the method of continuously launching new models to attract consumers and expand the market share. The production method of multiple varieties and small batches of models has gradually become the mainstream of the automobile production method. In the production and manufacturing of automobiles, in order to meet market demands, the situation of co-line production of multiple models is very common. For the clamps on the production line, the support points with the bodies of different models are generally different. Therefore, when different models are produced on the same line, it is difficult for the clamps to be applicable to different models, and the clamps need to be replaced according to the models. To solve the above problems, the embodiments of the present invention propose a clamp for automobile production and an automobile general assembly system. The above-mentioned clamp for automobile production and the automobile general assembly system will be specifically described below.

[0041] In the first aspect, referring to Figure 1 and Figure 2 、 Figures 5 to 7, the carrier for automobile production provided by the embodiment of the present invention includes a first support member 11 and a positioning structure. A plurality of positioning grooves 111 are formed in the first support member 11. The plurality of positioning grooves 111 are arranged at intervals along a first direction and extend through along a second direction. The positioning grooves 111 are used for the sill structure 21 of the body-in-white 20 to extend into, and are used for positioning the body-in-white 20 along the first direction. The positioning structure extends along the first direction, and both ends of the positioning structure respectively extend to both sides of the plurality of positioning grooves 111 along the first direction. The positioning structure is used for positioning the body-in-white 20 with any sill structure 21 extending into the positioning groove 111 along the second direction; the second direction is perpendicular to the first direction, and both the second direction and the first direction are perpendicular to the height direction of the carrier for automobile production 10.

[0042] Among them, the first direction is parallel to the width direction of the body-in-white 20, and the first direction can be referred to Figures 1 to 3 , Figure 5 and Figure 7 the Y direction shown in. The second direction is parallel to the length direction of the body-in-white 20, and the second direction can be referred to Figures 1 to 3 , Figure 5 and Figure 6 the X direction shown in. The height direction of the carrier for automobile production 10 is parallel to the height direction of the body-in-white 20, and the height direction of the carrier for automobile production 10 can be referred to Figures 1 to 3 , Figures 5 to 7 the Z direction shown in.

[0043] The carrier for automobile production 10 further includes a carrier lifting arm 17 and a support 16. The support 16 is connected to the bottom of the carrier lifting arm 17, and the first support member 11 is connected to the support 16. The connection manner between the first support member 11 and the support 16 can be a fixed connection or a detachable connection. The carrier for automobile production 10 specifically includes two carrier lifting arms 17, two supports 16 and two first support members 11. The two carrier lifting arms 17, two supports 16 and two first support members 11 are all symmetrically arranged along the first direction. When the carrier for automobile production 10 holds the body-in-white 20, the support 16 is located below the body-in-white 20, and the support 16 extends along the Y direction.

[0044] The notch of the positioning groove 111 faces upward, and the positioning groove 111 extends through the first support member 11 along the second direction. The shape of the cross-section of the positioning groove 111 perpendicular to the second direction can be rectangular, V-shaped, etc. The body-in-white 20 includes a sill structure 21, and the sill structure 21 includes a sill underflange 212. The positioning groove 111 is used for the sill underflange 212 to extend into. The positioning groove 111 is used for limiting the sill underflange 212 along the first direction to realize the positioning of the body-in-white 20 along the first direction.

[0045] The number of the positioning grooves 111 can be determined according to the number of vehicle models to be adapted by the carrier 10 for automobile production. For example, the number of the positioning grooves 111 can be two, three, etc. The positioning grooves 111 at different positions correspond to white bodies 20 with different widths. By designing several positioning grooves 111 at different positions, the carrier 10 for automobile production can be applicable to several vehicle models with different widths.

[0046] The positioning groove 111 has a groove bottom wall 112. The groove bottom wall 112 of the positioning groove 111 can be used to support the sill structure 21 of the white body 20, or the groove bottom wall 112 of the positioning groove 111 may not be used to support the sill structure 21 of the white body 20. In this case, the sill structure 21 of the white body 20 can be supported by other support structures.

[0047] A positioning notch 211 is formed in the lower flanging 212 of the sill of the sill structure 21. The positioning structure is used to cooperate with the positioning notch 211 of the sill structure 21 to realize the positioning of the white body 20 in the second direction. The positioning structure can only include a positioning member 12, or the positioning structure can also include a plurality of positioning segments. The two ends of the positioning structure in the first direction respectively extend to both sides of the plurality of positioning grooves 111 in the first direction, so that the positioning structure can be used for the X-direction positioning of white bodies 20 with different widths.

[0048] In the carrier 10 for automobile production provided by the embodiment of the present invention, a plurality of positioning grooves 111 are formed in the first support member 11, and the positioning structure extends in the first direction. When vehicle models with different widths are produced in a common line, for example, when three vehicle models with different widths, namely a sedan, an SUV (Sport Utility Vehicle), and an MPV (Multi-Purpose Vehicle), are produced on the same line, the Y-direction positioning of white bodies 20 with different widths can be realized through the positioning grooves 111 at different positions, and the X-direction positioning of the white body 20 with any sill structure 21 extending into the positioning groove 111 can be realized through the positioning structure. Therefore, the carrier 10 for automobile production can be applicable to vehicle models with different widths and meet the co-line production of vehicle models with different widths.

[0049] In the related art, in order to meet the co-line production of vehicle models with different widths, the carrier is usually designed as a replaceable or adjustable structure. The replaceable carrier needs to be designed synchronously with the vehicle body. For the adjustable carrier, the carrier needs to be adjusted every time the vehicle model is changed. In the embodiment of the present invention, the carrier 10 for automobile production has a simple structure and is easy to operate. When vehicle models with different widths are produced in a common line, there is no need to replace or adjust the carrier, which can save resources, reduce costs, and improve the production efficiency and the co-line production capacity of multiple vehicle models on the production line, and can avoid the waste of resources, high production costs and process costs, and low efficiency caused by replacing the carrier with the vehicle model.

[0050] In the related art, to achieve the co-line production of vehicle models with different widths, it is usually necessary to reserve a unified coordinate position at the bottom of the vehicle for the vertical positioning pin. The vertical positioning pin is usually connected to a relatively long cantilever in the Y direction on the carrier support. The relatively long cantilever will seriously interfere with the design of the vehicle body and the layout of other components. For example, the layout of line pipelines and installation points, etc. In the carrier 10 for vehicle production provided by the embodiment of the present invention, the traditional vertical positioning pin is cancelled, and there is no need to provide a relatively long cantilever in the Y direction for installing the vertical positioning pin, which can shorten the size of the support 16 in the first direction in the carrier 10 for vehicle production, thereby reducing the space occupied by the carrier 10 for vehicle production under the body-in-white 20, leaving more space and flexibility for the design of the body-in-white 20 and the layout of other components. At the same time, when assembling other components under the vehicle bottom, more operating space can be vacated as much as possible.

[0051] In some embodiments, referring to Figure 2 and Figure 3 , the positioning structure only includes a positioning member 12, and the length of the positioning member 12 in the first direction is greater than or equal to the size of the plurality of positioning grooves 111 in the first direction.

[0052] Among them, the shape of the cross-section of the positioning member 12 perpendicular to the first direction is adapted to the shape of the positioning notch 211. The length of the positioning member 12 is greater than or equal to the size of the plurality of positioning grooves 111 in the first direction, so that the positioning member 12 can be commonly used for the X-direction positioning of body-in-whites 20 with different widths. When the shape of the positioning notch 211 is arc-shaped, the shape of the cross-section of the positioning member 12 is circular. In other embodiments, the shape of the positioning notch 211 can be rectangular, and at this time, the shape of the cross-section of the positioning member 12 is rectangular. In this embodiment, the positioning member 12 with an integrated structure is set as the positioning structure, which has a simple structure and is conducive to installation.

[0053] In some embodiments, the positioning structure includes a plurality of positioning segments, and the plurality of positioning segments are arranged at intervals in the first direction. The number of positioning segments is equal to the number of positioning grooves 111, and the plurality of positioning segments are respectively used for the X-direction positioning of body-in-whites 20 with multiple different widths. Along the first direction, the arrangement spacing and the starting position of the plurality of positioning segments can be the same as the arrangement spacing and the starting position of the plurality of positioning grooves 111.

[0054] In some embodiments, referring to Figure 2 and Figure 3 , an installation groove 115 is formed in the first support member 11, and the installation groove 115 intersects with the plurality of positioning grooves 111; the positioning member 12 is arranged in the installation groove 115, and the positioning member 12 straddles the plurality of positioning grooves 111.

[0055] Among them, the positioning member 12 can be fixed in the installation groove 115 or directly placed in the installation groove 115. The installation groove 115 extends in the first direction, and the shape of the cross-section of the installation groove 115 perpendicular to the first direction can be rectangular, circular, etc. In this embodiment, the positioning member 12 is integrally installed on the first support member 11, and the structure is compact.

[0056] In some embodiments, referring to Figure 3 and Figure 6 , the fixture 10 for automobile production further includes an elastic buffer member 13. The elastic buffer member 13 is arranged in the installation groove 115. The positioning member 12 is placed in the installation groove 115 and is located above the elastic buffer member 13.

[0057] Among them, the elastic buffer member 13 can be a rubber pad, for example, a vulcanized rubber pad, and the elastic buffer member 13 can also be a spring. When the elastic buffer member 13 is a rubber pad, the elastic buffer member 13 extends in the first direction, and the shape of the cross-section of the elastic buffer member 13 perpendicular to the first direction can be rectangular, circular, etc. The elastic buffer member 13 can be connected to the first support member 11 or not, and is only placed in the installation groove 115. The elastic buffer member 13 can be connected to the positioning member 12 or only in contact with the positioning member 12 without connection.

[0058] During the process of the white body 20 descending and the lower flange 212 of the sill extending into the positioning groove 111, the white body 20 will first contact the positioning member 12. Without buffering, it is easy to cause the white body 20 to be damaged and the positioning member 12 to be easily worn. In this embodiment, the elastic buffer member 13 plays a role of collision buffering, which can avoid damaging the white body 20 during the positioning process and can reduce the wear of the positioning member 12 during the positioning process.

[0059] In some embodiments, referring to Figure 2 and Figure 3 , the fixture 10 for automobile production further includes a limiting member 14 connected to the first support member 11. The limiting member 14 covers a part of the notch of the installation groove 115; along the height direction of the fixture 10 for automobile production, the orthographic projection of the limiting member 14 and the orthographic projection of the positioning groove 111 do not overlap.

[0060] Among them, the limiting member 14 has an L-shaped structure. The limiting member 14 includes a limiting plate 141 and a connecting plate 142 that are perpendicular to each other. The number of the limiting members 14 can be two, and the two limiting members 14 are symmetrically arranged. The two limiting plates 141 respectively cover both ends of the notch of the installation groove 115. The limiting member 14 does not cover the notch of the positioning groove 111.

[0061] The limiting member 14 is detachably connected to the first support member 11. Specifically, the limiting member 14 is connected to the first support member 11 through a second fastener 19, and the second fastener 19 is a screw. A second mounting hole is formed in the connecting plate 142, and a second threaded hole corresponding to the second mounting hole is formed in the first support member 11. The second fastener 19 passes through the second mounting hole and is threadedly connected to the second threaded hole.

[0062] When the positioning member 12 and the elastic buffer member 13 are assembled, first place the elastic buffer member 13 into the mounting groove 115, and then place the positioning member 12. After the positioning member 12 is placed, connect the two limiting members 14 to the first support member 11 through two second fasteners 19 respectively. Through the limiting member 14, the positioning member 12 can be limited within the mounting groove 115 to prevent the positioning member 12 from disengaging from the mounting groove 115.

[0063] In some embodiments, referring to Figure 4 and Figure 7 , the positioning groove 111 has a groove bottom wall 112, and the groove bottom wall 112 is used to support the sill structure 21 of the white body 20 in the height direction of the carrier 10 for automobile production. Wherein, the groove bottom wall 112 is used to contact the downward flanging 212 of the sill of the white body 20 to position the white body 20 in the Z direction and support the sill structure 21 of the white body 20 in the Z direction. In this embodiment, the first support member 11 not only plays the role of Y-direction positioning but also plays the role of Z-direction support, with a simple and compact structure.

[0064] In some embodiments, the carrier 10 for automobile production further includes a second support member 15. Along the second direction, the second support member 15 is arranged at an interval from the first support member 11, and the second support member 15 is used to support the sill structure 21 of the white body 20 in the height direction of the carrier 10 for automobile production.

[0065] Wherein, the second support member 15 has a support surface, and the support surface is used to support the downward flanging 212 of the sill of the white body 20. The dimension of the support surface in the first direction is greater than or equal to the dimension of the plurality of positioning grooves 111 in the first direction. The number of the second support members 15 is two, and the two second support members 15 are symmetrically arranged. The second support member 15 is connected to the carrier lifting arm 17, and the connection manner between the second support member 15 and the carrier lifting arm 17 can be a fixed connection or a detachable connection. In this embodiment, the second support member 15 and the first support member 11 jointly support the white body 20 in the Z direction, which can ensure the support stability of the white body 20.

[0066] In some embodiments, referring to Figure 4 and Figure 7, the positioning groove 111 has two straight side walls 113 oppositely arranged in the first direction. The straight side walls 113 are used to contact the downward flanging 212 of the sill of the white body 20 to achieve the positioning of the white body 20 in the first direction. Among them, the straight side walls 113 are used to contact the side surface of the downward flanging 212 of the sill and limit the downward flanging 212 of the sill in the first direction to achieve the positioning of the white body 20 in the first direction. In this embodiment, the straight side walls 113 and the downward flanging 212 of the sill have a certain contact area, which can ensure the positioning effect of the white body 20 in the first direction.

[0067] In some embodiments, referring to Figure 4 , the positioning groove 111 further has two guiding walls 114 oppositely arranged in the first direction. The bottoms of the two guiding walls 114 are respectively connected to the tops of the two straight side walls 113; in the direction from the notch of the positioning groove 111 to the bottom of the positioning groove 111, the distance between the two guiding walls 114 gradually decreases. Among them, the cross-sectional shape of the guiding wall 114 is arc-shaped, or the guiding wall 114 is an inclined wall surface. Along the height direction of the positioning groove 111, the height of the guiding wall 114 can be greater than or equal to the height of the straight side wall 113. In this embodiment, during the process of the downward flanging 212 of the sill extending into the positioning groove 111, it can guide the downward flanging 212 of the sill to gradually enter between the two straight side walls 113.

[0068] In some embodiments, referring to Figure 2 and Figure 3 , the carrier 10 for automobile production further includes a support 16, and the first support member 11 is detachably connected to the support 16.

[0069] Among them, the support 16 is connected to the bottom of the carrier lifting arm 17, and the support 16 is perpendicular to the carrier lifting arm 17. The connection mode between the support 16 and the carrier lifting arm 17 can be a fixed connection, for example, welding. The connection mode between the support 16 and the carrier lifting arm 17 can also be a detachable connection, for example, bolt connection.

[0070] The connection mode between the first support member 11 and the support 16 can be bolt connection, clamping connection, etc. The first support member 11 is specifically connected to the support 16 through a plurality of first fasteners 18. The first fasteners 18 are bolts, and the number of the first fasteners 18 can be two, three, four, etc. A plurality of first mounting holes are formed on the first support member 11, and first threaded holes corresponding to the first mounting holes are formed on the support 16.

In the embodiment of the present invention, the first support member 11 is detachably connected to the support 16, which is convenient for the maintenance and replacement of the first support member 11.

[0071] The working principle of the above-mentioned carrier 10 for automobile production is as follows:

[0072] During the use of the gripper 10 for automobile production, the first component 11 and the second component 15 extend into the bottom of the body-in-white 20. Then the body-in-white 20 descends. During the descent of the body-in-white 20, the positioning notch 211 of the lower flanging 212 of the sill cooperates with the positioning member 12 to position the X-direction of the body-in-white 20. At the same time, during the descent of the body-in-white 20, the lower flanging 212 of the sill extends into one of the positioning grooves 111 until the bottom wall 112 of the positioning groove 111 contacts the lower flanging 212 of the sill to position the Y-direction of the body-in-white 20. When the positioning is in place, the bottom wall 112 cooperates with the second component 15 to jointly position the Z-direction of the body-in-white 20 and support the body-in-white 20 in the Z-direction.

[0073] In a second aspect, an embodiment of the present invention provides an automobile general assembly system, which includes the gripper 10 for automobile production provided in the above first aspect. The automobile general assembly system further includes an upper carrier. The top of the gripper boom 17 in the gripper 10 for automobile production is hinged to the upper carrier. The first component 11 is connected to the bottom of the gripper boom 17 through a support 16, and the second component 15 is connected to the bottom of the gripper boom 17.

[0074] Since the automobile general assembly system includes the above-mentioned gripper 10 for automobile production, it also has the beneficial effects of the above-mentioned gripper 10 for automobile production, which will not be elaborated here.

[0075] The above embodiments are only preferred embodiments given to fully illustrate the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or transformations made by those skilled in the art on the basis of the present invention are within the protection scope of the present invention.
