AI Technical Summary
Due to the long length of the fixing plate, the length of the guide rod seat increases, the entire structure becomes larger and the weight increases, and the compactness and lightweight design lacks.
Design an improved compact casting fixture, by providing a half-waist mounting hole and a guide rod seat plate on the fixing plate, the guide rod seat is arranged under the guide rod seat, and connected to the guide rod seat plate on the bottom surface of the reinforcement rib. Reduce material for fixing plates, save guide length, and optimize structure to reduce overall size and weight.
It has achieved the saving of 40mm for a single guide rod at the same installation height, totaling 80mm. The new casting fixture is more compact and lighter, and the material is 20%, achieving the purpose of reducing costs and increasing efficiency.

Abstract
Description
Technical Field
[0001] The utility model relates to an improved compact casting fixing frame, which is used for fixing the double guide rods and the pool wall in the coupling device of the submersible sewage pump. Background Art
[0002] The existing conventional casting has a simple fixed structure and is integrally cast. Figure 1 , Figure 2 , Figure 3 11 is a waist hole for installation, 12 is a fixing plate, 13 is a reinforcing rib, 14 is a guide rod seat, and 15 is a guide rod seat plate. a. The fixing plate is the main structure, and the waist hole for installation is cast outside the reinforcing rib; b. The guide rod seat plate is extended and cast as one piece with the fixing plate. The reinforcing rib is used to strengthen the connection with the fixing plate; c. A guide rod seat is cast on the guide rod seat plate; the guide rod seat is located above the guide rod seat; d. The guide rod seat is a conical cylinder; e. The casting fixing frame is an integral casting, an inverted fixing frame, and its guide rod seat part contacts the guide rod; its waist hole part passes through the expansion bolt screw, and the nut is tightened to complete the installation. Figure 4 To install the structure: Figure 4 Middle: 10 fixing frame; 17 guide rod. The existing casting fixing frame has the problem that the fixing plate in the structure is long, and the guide rod seat is located above the guide rod seat, which increases the length of the guide rod seat, so the entire casting fixing frame structure becomes larger and heavier, so it is urgent to improve the existing casting fixing frame. Summary of the invention
[0003] The purpose of the utility model is to overcome the above-mentioned problems existing in the casting fixing frame in the prior art and provide an improved compact casting fixing frame. The utility model designs an improved compact casting fixing frame, including a fixing plate, characterized in that two semi-waist-shaped mounting holes are provided on the left and right sides of the fixing plate, a guide rod seat plate extending forward is provided at both ends of the bottom of the fixing plate, and a guide rod seat is provided on the inner bottom surface of the top of the guide rod seat plate. Reinforcement ribs are provided at both ends of the fixing plate, and the bottom surface of the reinforcement ribs is connected to the guide rod seat plate. The advantages of the utility model are: the semi-waist-shaped mounting holes are arranged inside the reinforcement ribs, which reduces the material used for the fixing plate. In order to ensure the strength of the fixing plate, the waist-shaped holes are changed to vertical semi-waist-shaped holes. Considering the space for the fixing frame to install the nut, the guide rod seat is arranged below the guide rod seat. Since the guide rod seat is relative to the lower side of the fixing plate, the guide rod length is indirectly saved. Under the same installation height, a single guide rod saves 40mm. The coupling device is a double guide rod configuration, which saves a total of 80mm in guide rod length. The new structure saves 20% of the material used for castings. Through some structural improvements, the new casting fixture is more compact and lighter, achieving the goal of reducing costs and increasing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
