Abstract
Description
Technical Field
[0001] This utility model relates to the industrial and mining fields, specifically a composite tooling for processing irregularly shaped motors. Background Technology
[0002] Due to continuous innovation and the expanding application scope of the mining motor industry, new types of mining motors have begun to flood the market. Under the demands of different operating conditions and functions, motors with unconventional structures have emerged, whose external shape and internal structure are designed to fully meet usage requirements. For example, the problem this invention aims to solve is the machining of an unconventional motor base for a permanent magnet variable frequency submersible pump. This motor base has two water pipes extending beyond the end face of the base, making it impossible to directly clamp onto the worktable of a CNC vertical lathe when milling and drilling the end face and inner diameter of the other side of the base. Furthermore, the structural limitations of the end face with the water pipes cause spindle interference during drilling on the CNC machine tool, necessitating the use of a conventional drilling machine with an extended drill rod. Utility Model Content
[0003] To solve the above problems, this utility model discloses a composite jig for machining irregularly shaped motor bases, consisting of a tire and a drilling jig.
[0004] The specific technical solution is as follows:
[0005] A composite jig for machining irregularly shaped motor bases, comprising a base and a pressure plate assembly, including:
[0006] The composite function drilling jig is provided with a positioning stop and a drill sleeve that cooperate with the machine base. The drill sleeves are evenly distributed on the composite function drilling jig. The composite function drilling jig also includes a first connecting bolt, which connects the composite function drilling jig to the machine base.
[0007] The heightened tire body is an integral welded structure. The heightened tire body includes a connecting plate. The upper surface of the connecting plate is provided with a tire stop, which is conformally set to the end face of the composite functional drilling jig. A second connecting bolt is also provided on the connecting plate. A support rib is provided below the connecting plate, and a base plate is connected below the support rib.
[0008] When using the multifunctional drilling jig, after the pressure plate is installed on the machine base, the drill jig is aligned with the crosshairs of the machine base through the grooves of the drill jig. The multifunctional drilling jig is connected to the machine base by the first connecting bolt. After drilling is completed, the multifunctional drilling jig, as a connector, connects the machine base and the connecting plate of the heightened tire body together by the second connecting bolt.
[0009] When using the heightened tire body, the base plate is connected to the worktable with a chuck. The composite function drill jig is aligned with the machine base through the positioning stop and the drill jig groove is aligned with the cross line of the machine base. The heightened tire body is aligned with the drill jig groove of the composite function drill jig through the tire groove. The heightened tire body, composite function drill jig, and machine base are connected by positioning stops, groove alignment, and bolts to form a rigid whole.
[0010] The positioning stop and connecting hole positions are standardized structures, and different models of machine bases can be adapted by replacing the composite function drill jig.
[0011] The tire stop and connecting light hole of the heightened tire body are standardized structures, maintaining versatility when used with different models of composite function drill jigs.
[0012] The advantages of this utility model are:
[0013] The use of a multi-functional drilling jig for positioning drill bits avoids the problems of tool vibration and threaded hole quality that occur when using extended drill rods for drilling due to the irregular structure of the machine base. Furthermore, since the tire body is a welded whole, the use of the multi-functional drilling jig avoids the problem of the incompatibility of the heightened tire body due to the different sizes and positions of the positioning stops and connecting screw holes of different irregular machine bases for different product models. This enhances the versatility of the heightened tire body and reduces the manufacturing cost of the jig due to different models and specifications of the workpiece. Attached Figure Description
