Description

Technical Field

[0001] The utility model relates to the technical field of milling and drilling, in particular to a cavity surface milling and drilling integrated tool. Background Art

[0002] Milling and drilling a cavity typically requires tooling designed based on the cavity's design requirements. When the cavity's shape is irregular, the tooling fixture must be contoured accordingly. When machining a small cavity that also requires drilling the inner cavity and milling a mounting surface, the tooling often places high demands on spatial arrangement.

[0003] At present, when processing workpieces with special cavities, holes need to be drilled on both the upper and side surfaces to form cavities, and a plane needs to be milled out on the upper surface for subsequent processing, installation, etc. When designing the processing tooling, two corresponding drilling positions are required to drill out the main chamber located at the top and the side chamber located at the side, and two sets of clamping cylinders need to be designed to clamp the workpiece. Correspondingly, two sets of clamping cylinders also need to be designed. When the overall volume of the cavity-type workpiece is small, the space reserved for workpiece processing is also small. The installation position required for the two sets of clamping cylinders is too large. When installed side by side, the outer diameter of the clamping cylinders is too large, and the axial spacing between the two is too large, making it impossible to clamp the small cavity workpiece synchronously. Therefore, how to design the tooling to meet the existing workpiece processing requirements and the installation space limitations has become a difficult point in the milling and drilling process. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: in order to overcome the shortcomings of the existing technology, the present invention provides an integrated milling and drilling tool for the surface of a cavity, with a reasonable layout of the tightening cylinders, which can effectively tighten and fix the main cavity and the side cavity, making it convenient for drilling the cavity and also facilitating the milling plane operation of the milling cutter.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a cavity surface milling and drilling integrated tooling for milling and drilling a cavity workpiece with a main cavity and a side cavity, the side cavity being located at the side and lower part of the main cavity, and the top of the main cavity being provided with an upper table, the tooling comprising a tightening assembly and a profiling positioning platform, the cavity workpiece being pressed against the left end face of the profiling positioning platform by the tightening assembly; the side end face of the profiling positioning platform is provided with a main inner groove corresponding to the inner concave of the right outer wall of the main cavity, and a side inner groove corresponding to the inner concave of the right outer wall of the side cavity, and the top of the profiling positioning platform is provided with a step surface for the upper table to sink and press-connect; the tightening assembly comprises a main tightening cylinder and a side tightening cylinder, the output end of the main tightening cylinder is pressed against the left outer wall of the main cavity, and the output end of the side tightening cylinder is pressed against the left outer wall of the side cavity, the output ends of the main tightening cylinder and the side tightening cylinder are staggered in the height direction, and the output ends of the main tightening cylinder and the side tightening cylinder are axially parallel.

[0006] In the above scheme, the contoured positioning platform is located on the right side of the workpiece. The main and side inner grooves are designed on the contoured positioning platform to correspond to the contour of the workpiece cavity, providing effective space for positioning and crimping. The tightening assembly is located on the left side of the workpiece, and the two cylinders are staggered in height. This not only adapts to the workpiece's external structure, that is, the side chamber is positioned below and to the side of the main chamber, but also allows for a rational layout for the installation of the two cylinders, allowing them to fit within the limited installation space, achieving separate tightening of the main and side chambers, and improving the reliability and stability of the tightening.

[0007] The tooling also includes an intermediate support column, which is positioned between the output ends of the main and side tightening cylinders. The lower surface of the upper table of the main chamber of the cavity workpiece is pressed against the intermediate support column. This intermediate support column provides further support for the upper table, providing excellent support.

[0008] Furthermore, the upper surface of the main chamber of the cavity workpiece is provided with two through-holes, respectively. The intermediate support column is located below one of the two holes, and the contour positioning platform is located below the other two holes. Both the intermediate support column and the contour positioning platform have recesses corresponding to the two holes. The recesses facilitate drilling the corresponding two holes on the upper surface and provide working space for the drill bit.

[0009] Furthermore, a main positioning protrusion is protruded from the right outer wall of the main chamber, and a main positioning cavity is formed on the inner wall of the main inner groove to cooperate with the main positioning protrusion. Through the cooperation between the main positioning protrusion and the main positioning cavity, the main chamber can be further positioned and cooperated with the main inner groove.

[0010] Furthermore, the right outer wall of the side chamber is provided with a side positioning protrusion, and the inner wall of the side inner groove is provided with a side positioning cavity that cooperates with the side positioning protrusion. Through the cooperation between the side positioning protrusion and the side positioning cavity, the side chamber can be further positioned and matched with the main inner groove.

[0011] Preferably, in order to facilitate the installation of the tightening cylinder, the tightening assembly includes a tightening box, the main tightening cylinder and the side tightening cylinder are fixed in the tightening box and the output ends extend from the left box wall of the tightening box.

[0012] Furthermore, the tightening box is provided with an air inlet and an air outlet. The air inlets of the main tightening cylinder and the side tightening cylinder are connected to the air inlet pipes, while the air outlets of the main tightening cylinder and the side tightening cylinder are connected to the air outlet pipes. Supplying air to both tightening cylinders through the same air inlet and outlet pipes effectively ensures stable pressure in both cylinders, facilitating the provision of stable and reliable pressure to the cavity workpiece from the same side.

[0013] The beneficial effects of the present invention are that the cavity surface milling and drilling tooling provided by the present invention has a rational structural design. The dual cylinders are staggered, making it effectively suitable for machining smaller workpieces and applications with confined installation spaces. The cylinder clamping side adopts a contoured design, facilitating the required workpiece clamping and drilling and milling operations. Simultaneous air intake in the dual cylinders effectively enhances the reliability and stability of the double-sided clamping operation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating the basic structure of the present invention only in a schematic manner. They therefore only show components relevant to the present invention, and directions and references (e.g., up, down, left, right, etc.) may be used solely to facilitate the description of features in the drawings. The following detailed description is therefore not to be taken in a limiting sense, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.

[0023] like Figures 1 to 5 The cavity surface milling and drilling integrated tool shown is the best embodiment of the present utility model. The tool is used for milling and drilling cavity workpieces.

[0024] like Figure 6 As shown, the cavity workpiece processed in this embodiment has a main cavity 16 and a side cavity 6. The side cavity 6 is located below and to the side of the main cavity 16. The top of the main cavity 16 has an upper table 5. The upper table 5 has ears on both sides, and the ears need to be drilled to form double ear holes 3.

[0025] like Figure 1 and Figure 4 As shown, the tooling is mounted on a work surface 8 and includes a clamping assembly and a contour positioning platform 7. During machining, the cavity workpiece is pressed against the left end face of the contour positioning platform 7 by the clamping assembly. This side end face of the contour positioning platform 7 has a main inner groove 12, corresponding to the right outer wall of the main chamber 16, and a side inner groove 15, corresponding to the right outer wall of the side chamber 6. The top of the contour positioning platform 7 has a stepped surface 13, which the upper table 5 lowers and presses against.

[0026] In this embodiment, in order to better position and match, as Figure 6 and Figure 5 As described above, the right outer wall of the main chamber 16 has a main positioning projection 17 protruding from its outer wall, and the right outer wall of the side chamber 6 has three side positioning projections 18 protruding from its outer wall, at the upper, middle, and lower ends. Correspondingly, the inner wall of the main inner groove 12 has a main positioning cavity 20 that mates with the main positioning projection 17. The inner wall of the side inner groove 15 has three side positioning cavities 14 that mate with the side positioning projections 18, at the upper, middle, and lower ends. The coordination of the positioning projections and the positioning cavities allows each chamber to be more closely positioned with its corresponding inner groove.

[0027] Correspondingly, such as Figure 5 As shown, the cooperation between the protrusion and the cavity can also be designed between the lower end surface of the upper table 5 and the step surface 13, so as to further improve the positioning and cooperation effect between the step surface 13 and the upper table 5.

[0028] The tightening assembly includes a main tightening cylinder 4, a side tightening cylinder and a tightening box 2. The main tightening cylinder 4 and the side tightening cylinder 1 are fixed in the tightening box 2 and the output ends extend from the left side wall of the tightening box 2. The output end of the main tightening cylinder 4 is pressed against the left outer wall of the main chamber 16, and the output end of the side tightening cylinder 1 is pressed against the left outer wall of the side chamber 6. The output ends of the main tightening cylinder 4 and the side tightening cylinder 1 are staggered in the height direction, and the output ends of the main tightening cylinder 4 and the side tightening cylinder 1 are axially parallel. The main tightening cylinder 4 and the side tightening cylinder 1 partially overlap in horizontal projection. As shown in FIG. Figure 3As shown, the two cylinders are staggered in height. This not only accommodates the workpiece's external structure, with the side chamber 6 positioned below and to the side of the main chamber 16, but also allows for a rational layout for the installation of the two cylinders, fully utilizing the height space for staggered layout. The two cylinders can partially overlap in horizontal projection, allowing them to fit within the limited installation space, enabling separate tightening of the main chamber 16 and the side chamber 6, thereby improving the reliability and stability of the tightening. Simultaneously, an air inlet pipe 9 and an air outlet pipe 10 are provided on the tightening housing 2. The air inlets of the main tightening cylinder 4 and the side tightening cylinder 1 are connected to the air inlet pipe 9, while the air outlets of the main tightening cylinder 4 and the side tightening cylinder 1 are connected to the air outlet pipe 10. Supplying air to both tightening cylinders through the same air inlet pipe 9 and air outlet pipe 10 effectively ensures stable pressure in both cylinders, facilitating the provision of stable and reliable pressure to the cavity workpiece from the same side.

[0029] In this embodiment, during the machining of a cavity workpiece, double-ear holes 3 need to be drilled on both sides of the upper table 5. Therefore, to better support the upper table 5, an intermediate support column 11 is fixed to the work surface 8 between the output ends of the main tightening cylinder 4 and the side tightening cylinder 1. The lower surface of the upper table 5 of the cavity workpiece's main chamber 16 is press-fitted against the intermediate support column 11. The intermediate support column 11 provides effective support during milling of the upper table 5, cavity drilling, and drilling of the double-ear holes 3.

[0030] At the same time, the middle support column 11 is located below the double ear holes 3 on one side, and the contour positioning platform 7 is located below the double ear holes 3 on the other side. The middle support column 11 and the contour positioning platform 7 are both provided with clearance grooves 19 corresponding to the double ear holes 3. The clearance grooves 19 are designed to provide working space for the drill bit during the drilling of the double ear holes 3, effectively avoiding the drill bit and preventing interference with the tooling parts.

[0031] The cavity surface milling and drilling integrated tooling designed in this way can effectively position the cavity workpiece through the contour design of the contour positioning platform 7. The two tightening cylinders are reasonably arranged and staggered in height, which can effectively save installation space. When processing small workpieces, the height staggered distribution makes it possible for part of the diameters of the two tightening cylinders to overlap in horizontal projection and share part of the height space, thereby realizing the installation of two tightening cylinders in a limited installation space. It is effectively suitable for processing smaller workpieces and occasions with narrow installation positions.

[0032] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
