[0022] The following describes in detail a convertible support unit according to an embodiment of the present invention with reference to the accompanying drawings.

[0023] Example:

[0024] Figure 1 A three-dimensional structural diagram of the transformable support unit provided in an embodiment of this utility model is shown; Figure 2 The front view of the convertible support unit provided in this embodiment of the present invention is shown; Figure 3 A three-dimensional structural diagram of the transformation bracket provided in an embodiment of this utility model is shown; Figure 4 A three-dimensional structural schematic diagram of the transformation bracket provided in an embodiment of this utility model is shown; Figure 5 This diagram illustrates a three-dimensional structure of the transformable support unit in another state according to an embodiment of the present invention. Figure 6 A three-dimensional structural diagram of a changeable support unit with a partial workpiece state provided in an embodiment of this utility model is shown. Figures 1 to 6 As shown, this utility model embodiment provides a changeable support unit, the purpose of which is to realize support positioning and quick switching of fixtures for at least two types of workpieces or two placement states of workpieces. The changeable support unit provided in this utility model embodiment includes: a support assembly 1, a flipping cylinder 2, a changing bracket 3, and a positioning assembly 4. The flipping cylinder 2 is mounted on the support assembly 1 and mechanically fixed to it. A rotatable flipping bracket 21 is provided on the upper part of the flipping cylinder 2. The flipping bracket 21 is driven by the flipping cylinder 2 to rotate around the rotating shaft on the flipping cylinder 2. The changing bracket 3 is mounted on the flipping bracket 21 and mechanically connected to it to realize the common flipping action of the changing bracket 3 with the flipping bracket 21. In this utility model embodiment, the changing bracket 3 can realize a flipping action of at least 90 degrees, that is, changing from a horizontal state to a vertical state (the vertical state is visible). Figure 5 The transformation bracket 3 is equipped with a first support block 36 and a second support block 37, which are used to realize at least two specifications of workpieces (such as...) by rotating the transformation bracket 3 itself. Figure 6The support and positioning of a certain automobile side panel assembly 5 (corresponding to a certain workpiece specification) can be either for supporting and positioning the workpiece in two different placement states. That is, the first support block 36 can achieve support and positioning for one workpiece specification, while the second support block 37 is idle. When changing to another workpiece specification, the flipping cylinder 2 drives the flipping bracket 21 and drives the rotating change bracket 3 to perform a corresponding flipping action. At this time, the second support block 37 can be used to achieve support and positioning for the other workpiece specification, while the first support block 36 is idle. The bracket assembly 1 and positioning assembly 4 are mechanically connected to at least one of the two flipping states of the change bracket 3 to achieve support and positioning for the change bracket 3, i.e., the bracket assembly 1 is used to achieve one flipping state of the change bracket 3 (i.e., as shown in the image). Figure 2 The positioning and limiting of the horizontal state (in the middle) when the change bracket 3 is flipped to another state, that is, as Figure 5 In the vertical position, the positioning component 4 can be used to position and limit the other flipped state of the change bracket 3. By setting the change bracket 3 to a flippable form, the adaptability and versatility of the changeable support unit are improved, enabling it to adapt to more workpiece specifications or more workpiece placement states.

[0025] In a convertible support unit according to an embodiment of this utility model, as a further design improvement, more specifically, the support assembly 1 includes: a mounting bracket 11, a first positioning support 12, and a tilting cylinder 2 mechanically fixed to the mounting bracket 11. Here, the tilting cylinder 2 is mechanically fixed to the side of the mounting bracket 11. The first positioning support 12 is disposed above the mounting bracket 11 and mechanically connected to it to achieve support positioning of the convertible support 3 in one state. In this state, the first positioning support 12 is mechanically connected to the second positioning block 33 to prevent unexpected rotation of the convertible support 3. The positioning assembly 4 includes: a positioning bracket 41 and a second positioning support 42. The second positioning support 42 is disposed above the positioning bracket 41 and mechanically connected to it to achieve support positioning of the convertible support 3 in another state. In this state, the second positioning support 42 is mechanically connected to the first positioning block 32 to prevent unexpected rotation of the convertible support 3. The mounting bracket 11 and the positioning bracket 41 are generally fixed to the ground or a fixture workbench to achieve mechanical fixation of the convertible support unit.

[0026] In a transformable support unit according to an embodiment of this utility model, as a further design improvement, more specifically, the transformable support 3 is further provided with: a connecting frame 31, a first positioning block 32, a second positioning block 33, a first connecting rod 34, and a second connecting rod 35. The connecting frame 31 is mechanically connected to the flipping support 21 to realize the joint flipping action of the connecting frame 31 and the flipping support 21. The first support block 36 is mechanically connected to the connecting frame 31 through the first connecting rod 34 to realize the support and positioning of a workpiece state (which can be understood as a workpiece specification). The second positioning block 33 is disposed on the connecting frame 31 and is mechanically connected to the first positioning support 12 to realize the transformation support 3 in one state (which can be understood as...). Figure 2 The first positioning block 32 is mounted on the connecting frame 31 and mechanically connected to the second positioning support 42 to achieve support and positioning for another workpiece state (which can be understood as another workpiece specification). The second support block 37 is mechanically connected to the connecting frame 31 via the second connecting rod 35 to achieve support and positioning for another workpiece state (which can be understood as another workpiece specification). Figure 5 The support positioning is shown in the vertical position. It is worth noting that the first support block 36, the second support block 37, the first connecting rod 34, and the second connecting rod 35 can be disassembled and replaced according to the specific workpiece specifications to accommodate the support positioning of more medium-sized workpieces.

[0027] In a convertible support unit according to an embodiment of this utility model, as a further design improvement, the convertible bracket 3 is further provided with: at least one first adjusting shim 38 and at least one second adjusting shim 39. The first adjusting shim 38 is disposed at the connection between the first support block 36 and the first connecting rod 34 to realize the position adjustment of the first support block 36; the second adjusting shim 39 is disposed at the connection between the second support block 37 and the second connecting rod 35 to realize the position adjustment of the second support block 37. By adjusting the thickness and number of the first adjusting shims 38 and the second adjusting shims 39, the position adjustment of the first support block 36 and the second support block 37 can be achieved, thereby improving the positioning and support accuracy of the workpiece.

[0028] It is worth noting that, as a further design improvement, by adjusting the number of the first support block 36, the second support block 37, the first connecting rod 34, and the second connecting rod 35, and by changing the structural form of the bracket 3, it can accommodate more (such as three, four, ...) workpiece specifications and models, including but not limited to the two workpiece specifications shown in the embodiment of this utility model. The corresponding flipping angle of the bracket 3 includes but is not limited to flipping 90 degrees. The bracket 3 can flip any number of angles between 0 degrees and 360 degrees, which will not be elaborated here.
