Description

Technical Field

[0001] This utility model relates to the field of processing tooling equipment, specifically to a general-purpose chemical tooling equipment for processing the end face and mounting surface of ship engine bases. Background Technology

[0002] As the core mounting base for power equipment (such as main engines and generators), the machining accuracy of the ship's engine base and mounting surfaces directly determines the operational stability of the equipment. Currently, in the shipbuilding industry, engine bases are divided into dozens of specifications based on load-bearing tonnage and main engine model, with a wide range of dimensions. Traditional machining methods using dedicated fixed tooling cannot adapt to changes in the overall size of the engine base. Each specification of engine base requires customized tooling, resulting in companies needing to store a large amount of tooling, occupying space, and increasing processing costs. Changing engine base models requires disassembling old tooling and hoisting new tooling, affecting work efficiency, and frequent hoisting also increases safety risks. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a universal machining fixture for rapid positioning and clamping of ship engine bases of different sizes and models under a unified datum.

[0004] The technical solution adopted by this utility model is as follows: A general-purpose machining fixture for machining ship engine bases includes two independent and symmetrically arranged support frames. The top of the two support frames on their adjacent sides is provided with a positioning reference surface for supporting the ship engine base. Each support frame has an auxiliary support surface parallel to the positioning reference surface on its outer side, and the height of the auxiliary support surface is less than the height of the positioning reference surface. It also includes multiple fixing components for fixing the ship engine base placed on the positioning reference surface. Each fixing component includes a height adjustment support, a stud, and a fixing... The system includes a fixing block and a fastening nut. The height adjustment support is located on the auxiliary support surface, and the top surface of the height adjustment support is flush with the fixing surface of the ship's engine base to be fixed. The stud is threadedly connected to a threaded hole located on the auxiliary support surface and / or on the positioning reference surface. The fixing block has a strip groove extending through its thickness in the middle, and the stud passes through the strip groove. The two ends of the fixing block are respectively placed on the fixing surface of the ship's engine base and the top surface of the height adjustment support. The fastening nut is screwed onto the stud and presses the fixing block tightly, thereby pressing and fixing the ship's engine base to the positioning reference surface.

[0005] Furthermore, the height-adjustable support has a height adjustment mechanism, making its top surface height adjustable to accommodate ship engine base fixing surfaces of different thicknesses.

[0006] Furthermore, the height adjustment support is a jack.

[0007] Furthermore, multiple threaded holes are distributed on the auxiliary support surface and the positioning reference surface.

[0008] Furthermore, the bottom of the two support frames is provided with a transverse guide rail, and the support frame is slidably connected to the guide rail by a slider; multiple locking holes are provided at intervals on the guide rail, and the bottom of the support frame is provided with locking bolts that cooperate with the locking holes to fix the distance between the two support frames.

[0009] The beneficial effects of this utility model are as follows: This utility model has multi-dimensional adjustability: the spacing of the support frame can be adjusted to adapt to different lengths of machine bases; the height of the support can be adjusted to match the fixing surface of machine bases of different thicknesses, ensuring that the fixing block is horizontally pressed; the studs are flexibly arranged through threaded holes and strip grooves to adapt to different fixing point positions, so that it can be adapted to various sizes and models of marine machine bases, reducing tooling change costs and improving processing efficiency.

[0013] To facilitate understanding of this utility model, it will be described more comprehensively and in detail below with reference to the accompanying drawings and preferred embodiments. However, the scope of protection of this utility model is not limited to the following specific embodiments.

[0014] like Figures 1-3 As shown in the figure, this embodiment provides a general machining fixture for processing ship engine bases, including two independent and symmetrically arranged support frames 1. The top of the two support frames 1 on their adjacent sides is provided with a positioning reference surface 11 for supporting the ship engine base 3. Each support frame 1 has an auxiliary support surface 12 parallel to the positioning reference surface 11 on its outer side, and the height of the auxiliary support surface 12 is less than the height of the positioning reference surface 11. The positioning reference surface 11 provides a unified positioning reference for the ship engine base 3, ensuring that engine bases of different sizes have consistent references during processing. The auxiliary support surface 12 provides an installation platform for the fixing components 2, and because its height is lower than the positioning reference surface 11, it does not affect the main positioning function of the ship engine base 3 on the positioning reference surface 11.

[0015] Multiple fixing components 2 are used to fix the ship's engine base 3 placed on the positioning reference surface 11. Each fixing component 2 includes a height adjustment support 21, a stud 22, a fixing block 23, and a fastening nut 24.

[0016] The height-adjustable support 21 is mounted on the auxiliary support surface 12, and its top surface is flush with the fixing surface of the ship's engine base to be fixed. The height-adjustable support 21 has a height adjustment mechanism, allowing its top surface height to be adjusted to accommodate fixing surfaces of different thicknesses on the ship's engine base. This ensures that both ends of the fixing block 23 (the fixing surface of the engine base and the top surface of the height-adjustable support) are in horizontal contact, preventing tilting or localized stress concentration during clamping. The height-adjustable support 21 can be adjusted using a jack via hydraulic pressure.

[0017] The stud 22 is threadedly connected to the threaded hole provided on the auxiliary support surface 12 and / or provided on the positioning reference surface 11, serving as the support and clamping shaft of the fixing block 23. Multiple threaded holes are distributed on the auxiliary support surface 12 and the positioning reference surface 11. By adjusting the position of the stud, it can adapt to the distribution of different ship engine base 3 fixing points.

[0018] The fixing block 23 has a strip groove that runs through its thickness in the middle. The stud 22 passes through the strip groove and its two ends are respectively placed on the fixing surface of the ship engine base 3 and the top surface of the height adjustment support 21. The fastening nut 24 is screwed onto the stud 22 and presses the fixing block 23, thereby pressing and fixing the ship engine base 3 on the positioning reference surface 11.

[0019] The bottom of each of the two support frames 1 is provided with a transverse guide rail, and the support frame 1 is slidably connected to the guide rail via a slider. Multiple locking holes are spaced apart on the guide rail, and the bottom of each support frame 1 is provided with locking bolts that mate with the locking holes to fix the distance between the two support frames 1. This support frame adjustment mechanism allows for the transverse adjustment of the distance between the two support frames 1 to accommodate the support requirements of ship engine bases 3 of different lengths.

[0020] With the aid of the teachings present in the foregoing description and related drawings, those skilled in the art will conceive of many modifications and other embodiments of the present invention. Therefore, it is to be understood that the present invention is not limited to the specific embodiments disclosed, and modifications and other embodiments are considered to be included within the scope of the appended claims. Although specific terms are used herein, they are used in a general and descriptive sense only and are not intended to be limiting.
