[0015] The present invention will be further described in detail below with reference to the accompanying drawings.
[0016] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
[0017] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0018] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0019] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0020] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0021] Example 1: like Figure 1-2 As shown, a special processing fixture for cover plates of new energy vehicle parts includes a base plate 1. Two clamping components are provided at both ends of the base plate 1. The clamping components include several pressing units. Each pressing unit includes several cylinders 2 and a positioning block group. The positioning block group is located below the workpiece and is used to position the components. The cylinders 2 are used to press the workpiece. The positioning block group includes a first positioning block 4, a second positioning block 5 and a third positioning block 6. The first positioning block 4 is provided with a first positioning pin at its top, the second positioning block 5 is provided with a second positioning pin at its top, the first positioning pin is rhomboid in shape, the second positioning pin is cylindrical in shape, and the third positioning block 6 is provided with a positioning groove.
[0022] The use of "one surface and two pins"—namely, the rhomboid first positioning pin, positioning groove, and cylindrical second positioning pin on the first positioning block 4, the second positioning block 5, and the third positioning block 6—ensures that the workpiece is uniquely and accurately positioned in the fixture, thus improving assembly consistency. The use of cylinder 2 to quickly complete the clamping and releasing actions significantly improves clamping efficiency.
[0023] The special processing fixture for new energy vehicle parts cover plates in this embodiment adopts a positioning block assembly, which can accurately and reliably position the workpiece. In addition, it works with the cylinder 2 to drive the copper pressure head 3 to rise and fall, quickly and conveniently pressing the workpiece onto the support cylinder 7. Through the buffer of the support cylinder 7, the workpiece damage and deformation can be effectively avoided, and the operation is convenient and efficient.
[0024] There are four cylinders 2, which are respectively located at the four corners of the workpiece. The cylinders 2 drive the pressure plate to rise and fall.
[0025] The pressure plate is provided with a copper pressure head 3 at its end, and the bottom of the copper pressure head 3 is in contact with the upper surface of the workpiece. The copper pressure head has a large contact area and moderate hardness, which can provide sufficient clamping force without damaging the surface of the workpiece. A support plate is provided below the copper pressure head 3. The top of the support plate is in contact with the lower surface of the workpiece. A support cylinder 7 is provided below the support plate. The support cylinder 7 can effectively support the weak area of the cover plate and prevent deformation caused by its own weight or external force. At the same time, when the workpiece is pressed, the support cylinder 7 is locked to prevent vibration or deformation during processing, thus ensuring the accuracy of operation in a fixed state.
[0026] The base plate 1 is provided with a plurality of guide pins 8, which pass through the workpiece; the top of the guide pin 8 is tapered, and the guide pin 8 is used for preliminary and rapid placement guidance of the workpiece.
[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
