These orientation terms are only for the convenience of describing the embodiments of the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the embodiments of the present application Figure 4 shown in the drawings. These orientation terms are only for the convenience of describing the embodiments of the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the embodiments of the present application

[0036] The embodiments of the present application provide an adjustable workbench 100. Please refer to Figures 1 to 6 , the adjustable workbench 100 includes a support main body 10, a table plate assembly 20, a support member 30, and multiple sets of workpiece limiting tooling 40

[0037] The support main body 10 includes a support plate 11

[0038] Figure 1 As shown in the drawings, the support main body 10 is provided with support legs 12, and the support legs 12 are in contact with the ground and support the support plate 11

[0039] In some other embodiments, the support main body 10 may also not have support legs 12. For example, the support plate 11 can be directly placed on other support structures such as a table

[0040] Please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 , the table plate assembly 20 is rotatably provided on the support plate 11. Among them, the table plate assembly 20 can be rotatably connected to the support plate 11, or can be rotatably connected to other structures of the support main body 10

[0041] The platen assembly 20 includes a platen 21. The platen assembly 20 rotates relative to the support plate 11 to change the angle between the platen 21 and the support plate 11. That is to say, the platen assembly 20 can rotate away from the support plate 11 to increase the angle between the platen 21 and the support plate 11, or can rotate towards the support plate 11 to decrease the angle between the platen 21 and the support plate 11.

[0042] Please refer to Figure 1 and Figure 2 The support member 30 is rotatably connected to one of the platen assembly 20 and the support plate 11 to support the platen assembly 20 at least on the support plate 11, so that the platen 21 can maintain an inclined state forming an angle with the support plate 11. That is to say, in addition to the inclined state, the platen 21 can also have other states. For example, the platen 21 can also have a flat state of lying flat on the support plate 11 (i.e., the platen 21 is parallel to the support plate 11).

[0043] Figure 1 and Figure 2 As shown in and, the support member 30 is rotatably connected to the platen assembly 20. Exemplarily, please refer to Figure 1 , Figure 2 and Figure 5 The platen assembly 20 can be provided with a mounting block 22. The mounting block 22 is provided on the platen 21 and faces the support plate 11. The support member 30 can be rotatably connected to the mounting block 22.

[0044] Please continue to refer to Figure 5 , the mounting block 22 can be provided with a shaft hole, the support member 30 is provided with a mounting post 31a, and the platen assembly 20 is provided with a fixing nut 23. The mounting post 31a is rotatably inserted into the shaft hole. That is to say, the mounting post 31a can rotate in the shaft hole. A part of the mounting post 31a extends outside the shaft hole and is threadedly connected to the fixing nut 23 to prevent the mounting post 31a from disengaging from the shaft hole through the fixing nut 23.

[0045] In some other embodiments, the support member 30 can also be rotatably connected to the platen assembly 20 in other ways. For example, a shaft hole can be directly provided on the platen 21, and the support member 30 is rotatably inserted into the shaft hole.

[0046] In some other embodiments, the support member 30 can also be rotatably connected to the support plate 11. For example, the support body 10 can be provided with a mounting block 22. The mounting block 22 is provided on the support plate 11 and faces the platen 21. The support member 30 is rotatably connected to the mounting block 22.

[0047] By rotating, the support member 30 can support the platen 21 forming different angles with the support plate 11. Thus, the platen 21 can be switched between multiple inclined states with different inclined angles.

[0048] Please refer to Figure 1 、 Figure 2 、 Figure 5 and Figure 6 such that any set of workpiece positioning tooling 40 is detachably connected to the platen 21.

[0049] The workpiece positioning tooling 40 is used to position the automotive component 200 during the assembly process of the automotive component 200.

[0050] Multiple sets of workpiece positioning tooling 40 are respectively used to assemble different automotive components 200. The different automotive components 200 can be automotive components 200 with the same shape but different size specifications, for example, automotive components 200 at the same position of different vehicle models. The different automotive components 200 can also be automotive components 200 with differences in shape, structure, etc.

[0051] That any set of workpiece positioning tooling 40 is detachably connected to the platen 21 means that any set of workpiece positioning tooling 40 can be installed on the platen 21 and can also be removed from the platen 21. At the same time, at least one set of workpiece positioning tooling 40 can be selected for installation according to the assembly requirements.

[0052] Exemplarily Figure 1 、 Figure 2 、 Figure 5 and Figure 6 as shown, one set of workpiece positioning tooling 40 is installed on the platen 21.

[0053] The specific structure of each set of workpiece positioning tooling 40 is not limited, as long as it can play a role in positioning the automotive component 200 during the assembly process.

[0054] Exemplarily, please refer to Figure 1 、 Figure 2 、 Figure 5 and Figure 6 such that at least one set of workpiece positioning tooling 40 can be provided with two positioning bumps 41 having card slots 41a. The two positioning bumps 41 are spaced apart on the platen 21. During the assembly process of the automotive component 200, the automotive component 200 can be simultaneously stuck in the card slots 41a of the two positioning bumps 41, so as to facilitate the assembly operation of the operator.

[0055] In order to ensure that the automotive component 200 can be reliably fixed in the card slot 41a in any inclined state of the platen 21, the distance between the opposite side walls of the card slot 41a can be designed according to the specific structure of the automotive component 200 to be assembled, so that after the automotive component 200 is inserted into the card slot 41a, the opposite side walls of the card slot 41a can jointly play a role in stopping the automotive component 200.

[0056] Please continue to refer to Figure 1 、 Figure 2 and Figure 6 According to the specific structure of the automotive component 200 to be assembled, the platen assembly 20 may further be provided with a workpiece support bump 24, and the workpiece support bump 24 is disposed on a side of the platen 21 facing away from the support plate 11. The workpiece support bump 24 may be detachably disposed on the platen 21 or may be non-detachably disposed on the platen 21. During the process of assembling the automotive component 200, the automotive component 200 may abut against the workpiece support bump 24, so as to further facilitate the operator to perform the assembling operation.

[0057] It can be understood that for the automotive component 200 that does not need to abut against the workpiece support bump 24, the workpiece support bump 24 may be detachably disposed. That is to say, when the workpiece support bump 24 is not needed, the workpiece support bump 24 is removed from the platen 21, or alternatively, the platen assembly 20 may not be provided with the workpiece support bump 24. During the process of assembling the automotive component 200, the automotive component 200 may abut against the platen 21, or alternatively, the automotive component 200 may also be supported only by the workpiece positioning tooling 40 without abutting against the platen 21.

[0058] The adjustable workbench 100 according to the embodiment of the present application can enable the operator to change the included angle between the platen 21 of the platen assembly 20 and the support plate 11 by rotating the platen assembly 20 by providing a rotatable platen assembly 20 on the support plate 11. At the same time, by rotating the support member 30 to support the platen assembly 20, the platen 21 can be kept in an inclined state forming an included angle with the support plate 11. Thus, the operator can adjust the inclination angle of the platen 21 to adjust the platen 21 to an inclined state suitable for his own body posture, thereby effectively reducing the operation fatigue degree.

[0059] In addition, it should be noted that for the setting mode in which the support member 30 is rotatably connected to the platen assembly 20, the support member 30 is connected to the platen assembly 20, and the platen assembly 20 will not be separated from the support member 30. The reliability of the support member 30 supporting the platen assembly 20 is relatively good. At the same time, the support member 30 is actually in contact with the support main body 10, and the support main body 10 can provide sufficient support force for the support member 30. During the process of the support member 30 supporting the platen assembly 20, the probability of the support member 30 loosening or rotating by itself is small. Therefore, compared with the setting mode in which the support member 30 is rotatably connected to the support plate 11, the setting mode in which the support member 30 is rotatably connected to the platen assembly 20 has higher reliability.

[0060] In one embodiment, please refer to Figures 1 to 6, for the adjustable workbench 100 in which the support member 30 is rotatably connected to the platen assembly 20, a plurality of limiting grooves 11a may be provided on the support plate 11, and the plurality of limiting grooves 11a are arranged in a first direction perpendicular to the rotation axis of the platen assembly 20. When the platen 21 is in an inclined state, the support member 30 is snapped into the corresponding limiting groove 11a.

[0061] The limiting groove 11a is used to limit the support member 30, so that the support member 30 can reliably support the platen assembly 20.

[0062] Different limiting grooves 11a correspond to different inclination angles of the platen 21. By snapping the support member 30 into different limiting grooves 11a, the platen 21 can be maintained in an inclined state with different inclination angles.

[0063] There are various ways to form the limiting groove 11a. Exemplarily, please refer to Figures 3 to 6 , the support plate 11 may be provided with a plate body 111 and a plurality of limiting ribs 112. One side of the plate body 111 close to the platen 21 has a recessed space formed by recessing. The plurality of limiting ribs 112 are arranged in the first direction in the recessed space to partition a plurality of limiting grooves 11a in the recessed space.

[0064] Figures 3 to 6 , a limiting groove 11a is formed between two adjacent limiting ribs 112. In addition, the opposite sides of the recessed space in the first direction respectively have a first wall surface 111a and a second wall surface 111b. The second wall surface 111b is located between the first wall surface 111a and the rotation axis of the platen assembly 20. A limiting groove 11a is formed between the limiting rib 112 closest to the first wall surface 111a and the first wall surface 111a, and a limiting groove 11a is also formed between the limiting rib 112 closest to the second wall surface 111b and the second wall surface 111b. This is equivalent to partitioning as many limiting grooves 11a as possible in the recessed space, so as to facilitate adjusting the inclination angle of the platen 21 to meet more adjustment requirements.

[0065] In some other embodiments, it may also be that a limiting groove 11a is formed between the limiting rib 112 closest to the first wall surface 111a and the first wall surface 111a, while no limiting groove 11a is formed between the limiting rib 112 closest to the second wall surface 111b and the second wall surface 111b. Or, a limiting groove 11a is formed between the limiting rib 112 closest to the second wall surface 111b and the second wall surface 111b, while no limiting groove 11a is formed between the limiting rib 112 closest to the first wall surface 111a and the first wall surface 111a. It may also be that no limiting groove 11a is formed between the limiting rib 112 closest to the first wall surface 111a and the first wall surface 111a and between the limiting rib 112 closest to the second wall surface 111b and the second wall surface 111b.

[0066] In some other embodiments, the plate body 111 may not be provided with a recessed space. For example, a plurality of limiting ribs 112 may be provided on the end surface of the plate body 111 close to the platen 21 and arranged along the first direction, and a limiting groove 11a is formed between two adjacent limiting ribs 112. However, compared with the plate body 111 without a recessed space, the plate body 111 provided with a recessed space can reduce the space occupied by the limiting ribs 112 in the thickness direction of the plate body 111.

[0067] Please continue to refer to Figure 3 、 Figure 5 and Figure 7 , on the side of the limiting rib 112 close to the rotation axis of the platen assembly 20, it can be recessed inward to form the first groove wall 112a of the limiting groove 11a, and on the side of the limiting rib 112 away from the rotation axis of the platen assembly 20, it can also be recessed inward to form the second groove wall 112b of the limiting groove 11a.

[0068] That is to say, the limiting groove 11a can be formed between the first groove wall 112a of one limiting rib 112 and the second groove wall 112b of an adjacent other limiting rib 112.

[0069] Figure 7 As shown, both the first groove wall 112a and the second groove wall 112b are arc surfaces. In some other embodiments, at least one of the first groove wall 112a and the second groove wall 112b can also be a plane inclined relative to the first direction.

[0070] Figure 3 and Figure 5 , the limiting groove 11a formed between the limiting rib 112 closest to the first wall surface 111a and the first wall surface 111a is actually also located between the second groove wall 112b of this limiting rib 112 and the first wall surface 111a, and the limiting groove 11a formed between the limiting rib 112 closest to the second wall surface 111b and the second wall surface 111b is actually also located between the first groove wall 112a of this limiting rib 112 and the first wall surface 111a.

[0071] The limiting rib 112 forms the first groove wall 112a and the second groove wall 112b by being recessed into the interior of the limiting rib 112, which enables two adjacent limiting ribs 112 to be connected together without being spaced apart, or a small spacing distance can be provided between two adjacent limiting ribs 112 to form the corresponding limiting groove 11a (the limiting rib 112 closest to the first wall surface 111a and the first wall surface 111a, as well as the limiting rib 112 closest to the second wall surface 111b and the second wall surface 111b, can also be connected together or have a small spacing distance), so that it is convenient to arrange as many limiting ribs 112 as possible in the limited area of the plate body 111, and then the number of limiting grooves 11a can be increased to meet more adjustment requirements.

[0072] In some other embodiments, at least one of the first groove wall 112a and the second groove wall 112b of the limiting rib 112 may not be recessed into the interior of the limiting rib 112. For example, at least one of the first groove wall 112a and the second groove wall 112b may be a plane perpendicular to the first direction.

[0073] In some other embodiments, the limiting groove 11a may not be formed by arranging a plurality of limiting ribs 112. For example, a partial area of the support plate 11 close to the side of the table plate 21 may be recessed to form a plurality of limiting grooves 11a.

[0074] In one embodiment, please refer to Figure 1 、 Figure 2 and Figure 5 , the support member 30 can be bent to form a connecting portion 31 and a limiting portion 32. The connecting portion 31 is rotatably connected to the table plate 21. For example, the connecting portion 31 can be rotatably connected to the mounting block 22 by arranging a mounting post 31a. When the table plate 21 is in an inclined state, the limiting portion 32 is snapped into the corresponding limiting groove 11a.

[0075] The support member 30 is bent to form the connecting portion 31 and the limiting portion 32, which enables the support member 30 to have a relatively high structural strength, thereby improving the reliability of the support member 30 in supporting the table plate assembly 20.

[0076] Figure 1 、 Figure 2 and Figure 5 As shown in

[0077] Figure 1 、 Figure 2 and Figure 5The shown support member 30 has two connecting portions 31, and the two connecting portions 31 are located at opposite ends of the limiting portion 32 and are respectively rotatably connected to the platen assembly 20. This structural form can effectively prevent the limiting portion 32 from deforming, thereby further improving the structural strength of the support member 30.

[0078] In some other embodiments, the support member 30 may also have only one connecting portion 31.

[0079] In some other embodiments, the support member 30 may not be provided with a limiting portion 32. For example, the connecting portion 31 can be directly snapped into the limiting groove 11a.

[0080] In addition, it should be noted that the above embodiments are only introduced by taking the adjustable workbench 100 with the support member 30 rotatably connected to the platen assembly 20 as an example. It can be understood that for the adjustable workbench 100 with the support member 30 rotatably connected to the support plate 11, a similar setting method to the above embodiments can also be adopted. The main difference is that a plurality of limiting grooves 11a are provided on the platen 21 instead of on the support plate 11. A recessed space formed by a depression can also be provided on one side of the platen 21 close to the support plate 11. The platen assembly 20 can be provided with a plurality of limiting ribs 112, and the plurality of limiting ribs 112 are arranged in the recessed space along the first direction to partition a plurality of limiting grooves 11a in the recessed space. The support member 30 rotatably connected to the support plate 11 can also be provided with a connecting portion 31 and a limiting portion 32. The connecting portion 31 can be one or two, and the support member 30 is rotatably connected to the support plate 11 through the connecting portion 31. The specific setting method can refer to the above embodiments and will not be elaborated here.

[0081] In one embodiment, please refer to Figures 1 to 6 , the support main body 10 can also be provided with a stop bar 13 having an avoidance groove 13a on the support plate 11. One side of the platen 21 is rotatably connected to the support plate 11, and the rotatable connection part is hidden in the avoidance groove 13a.

[0082] Specifically, the purpose of setting the stop bar 13 is to block the rotatable connection part of the platen 21 and the support plate 11 to avoid as much as possible sundries from falling into the rotatable connection part of the platen 21 and the support plate 11 and affecting the rotation of the platen assembly 20. And the avoidance groove 13a can avoid the rotatable connection part of the platen 21 and the support plate 11 to ensure that the platen assembly 20 can rotate normally.

[0083] In one embodiment, please refer to Figure 6 , the adjustable workbench 100 can also be provided with a material box 50. The material box 50 is arranged on the support main body 10 to be used for containing parts such as standard parts for assembling the automotive parts 200 to facilitate the operation of the operator.

[0084] The setting position of the material box 50 on the support main body 10 is not limited. However, for the convenience of the operator, the material box 50 can be set as close as possible to the operator. For example, please refer to Figure 6 , the material box 50 can be set on the side wall of the support plate 11 close to the operator. For the adjustable workbench 100 provided with the stop bar 13, the material box 50 can also be set on the side of the stop bar 13 away from the table board assembly 20.
