[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the scope of implementation of the present invention is not limited thereto.
[0017] It should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention 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 therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0018] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0019] like Figure 1 , Figure 2 and Figure 3 As shown, a processing device with a cantilever lower support in this embodiment includes a base 1, a vertical plate 2 and a template 3 are arranged above the base 1, the vertical plate 2 is perpendicular to the base 1 and fixedly connected, the template 3 is fixedly connected to the base 1 through a support 4, a clamping device 5 and a positioning device 6 are arranged on the front side of the vertical plate 2, and preferably the positioning device 6 includes at least two positioning columns, which are respectively matched with the connecting holes of the U-shaped body 72 with the cantilever lower support 7 to position the cantilever lower support 7, and the clamping device 5 presses the U-shaped body 72 to fix the cantilever lower support 7, the template 3 is located on the rear side of the vertical plate 2, and drill sleeve holes 31 are arranged at both ends of the template 3, and the axis of the drill sleeve hole 31 is vertically arranged. After the cantilever lower support 7 is fixed to the front side of the vertical plate 2, the end of the cantilever 71 with the cantilever lower support 7 is located below the template 3, and the position of the connecting hole to be processed of the cantilever 71 is arranged corresponding to the drill sleeve hole 31. When in use, the cantilever 71 with the cantilever lower support 7 is extended toward the rear side of the vertical plate 2, the U-shaped body 72 is fitted with the side wall of the vertical plate 2, the positioning device 6 cooperates with the connecting hole of the U-shaped body 72 to realize the positioning of the cantilever lower support 7, and the cantilever lower support 7 is fixed by the clamping device 5. The position of the connecting hole to be processed of the fixed cantilever 71 corresponds to the drill sleeve hole 31, and the drill bit of the drilling device passes through the drill sleeve hole 31 to process the connecting hole of the cantilever 71.
[0020] The aperture of the drill sleeve hole 31 = the aperture of the cantilever 71 connecting hole + (1-3) mm. Due to a certain tolerance range in the workpiece processing and production process, such as the tolerance range of the cantilever 71 connecting hole in the utility model is ±1 mm, and due to slight deformation of the cantilever 71 after casting, the utility model makes the aperture of the drill sleeve hole 31 1-3 mm larger than the standard aperture of the workpiece cantilever 71 connecting hole. During the drilling process, the gap between the drill bit and the drill sleeve hole 31 is increased, and the restriction of the drill sleeve hole 31 on the drill bit is reduced. Therefore, the aperture of the connecting hole after processing not only meets the requirements, but also helps to ensure the uniformity of the hole wall of the cantilever 71 connecting hole after drilling, thereby ensuring the service life of the cantilever lower support 7.
[0021] The clamping device 5 includes a clamping block 51, a screw 52 and a locking nut 53. One end of the screw 52 is connected to the vertical plate 2, and the other end passes through the clamping block 51 and is threadedly connected to the locking nut 53. The screw 52 passes through the weight-reducing hole in the middle of the U-shaped body 72 with the cantilever lower support 7. The U-shaped body 72 is in contact with the vertical plate 2. The clamping block 51 is pressed against the middle of the U-shaped body 72 by the locking nut 53, thereby achieving fixation of the cantilever lower support 7.
[0022] After the U-shaped body 72 with the cantilever lower support 7 is fixed to the front side of the vertical plate 2 by the positioning unit and the fixing unit, the cantilever 71 extends to the rear side of the vertical plate 2, so that the end of the cantilever 71 is located below the drill sleeve hole 31. After the cantilever lower support 7 is fixed to the front side of the vertical plate 2, the top of the vertical plate 2 or the two sides of the top of the vertical plate 2 are not higher than the upper part of the U-shaped body 72 with the cantilever lower support 7 after fixation, which facilitates the cantilever 71 to extend to the rear side of the vertical plate 2, so that the position where the connecting hole needs to be processed at the end of the cantilever 71 is located below the drill sleeve hole 31.
[0023] The two drill sleeve holes 31 are symmetrically arranged at the two ends of the template 3, and the cantilever lower support 7 includes two left-right symmetrical structures. The neutral plate 2 of the utility model can be used to fix the U-shaped body 72 with the left and right cantilever lower supports 7. After fixation, the cantilevers 71 of the left and right cantilever lower supports 7 extend from the two sides of the vertical plate 2 to the bottom of the drill sleeve holes 31 of the template 3, thereby realizing that a set of molds can be used to process the connecting holes of the left and right cantilever lower supports 7.
[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
