Abstract
The invention discloses a loam core locating fixator of a fixed pitch propeller, relating to a fixator of a mesopore loam core used for pouring a marine copper propeller. The loam core locating fixator comprises a riser box and a loam core arbor, the loam core arbor is vertically arranged, the lower end of the loam core arbor is fixedly connected with the center position on the riser box; the loam core locating fixator further comprises riser box weights, a loam core fixing weight and a loam core locating bushing; the two riser box weights are parallel to each other and are horizontally arranged at two sides of the loam core arbor; one loam locating bushing vertically arranged is welded in the middle of the loam core fixing weights horizontally arranged; the loam core fixing weight is perpendicular to the riser box weights and is pressed on the two riser box weights, and the loam core locating bushing is sheathed on the loam core arbor; the riser box weights are connected with the loam core fixing weight by a locking component; and an adjusting screw is arranged on the side surface of the loam core locating bushing. According to the loam core locating fixator of the fixed pitch propeller, the problems that the existing mesopore loam core used for the copper propeller is large in operation procedure workload and low in working efficiency can be solved.
Description
Technical field
The present invention relates to the fixture in the mesopore loam core of copper propeller cast use peculiar to vessel, be particularly suitable for the mesopore loam core device for positioning and securing of middle-size and small-size copper FPP screw.
Background technology
The Main Function of FPP copper propeller mesopore loam core fixture peculiar to vessel (hereinafter to be referred as fixture) is that the mesopore loam core is stable in the seat of loam core.In the casting process, overcome buoyancy and the impact of the high-temperature copper liquid that flows in the casting mold, guarantee that the loam core is not subjected to displacement.Thus, the reliability of loam core fastening means and fastener thereof directly affects the quality of product.
At present, the chief component element of domestic FPP copper propeller mesopore of the same trade loam core fastener is: rising head case foundary weight, special-purpose pull bar etc.
In the same industry, most of producers often adopt the firm loam core of mode of combination weldment at home.During operation, professional welder's support must be arranged, need to adjust the series of processes operation such as rising head case foundary weight-adjustment loam core position-blanking-welding-fastening and just can finish.Whole operating process needs 30～60 minutes, and wherein, the welding sequence workload accounts for more than 60%. and whole operational sequence workload increases, and operating efficiency is very low.Simultaneously, in the welding process, a large amount of welding slags enter the casting mold die cavity, the cleaning difficulty, and the casting flaws such as cinder hole very easily appear in foundry goods.
Summary of the invention
The invention provides a kind of spacing oar loam core device for positioning and securing, the operational sequence workload that the invention solves the fastener existence of existing copper propeller mesopore loam core is large, the problem that operating efficiency is very low.The present invention is on the basis of traditional fastener, and optimizing structure design for production provides simply, reliable, practical, quick, efficient technological equipment, its objective is the raising effect, and the operating process of simplifying working process alleviates staff labor intensity.
For addressing the above problem, the present invention adopts following technical scheme: a kind of spacing oar loam core device for positioning and securing, comprise rising head case 7 and core rod 5, and core rod 5 vertically arranges, and core rod 5 lower ends are fixedly connected on center above the rising head case 7; Also comprise rising head case foundary weight 1, loam core fixedly foundary weight 2 and loam core positioning sleeve 3; Two rising head case foundary weight 1 are parallel to each other and are horizontally placed on the both sides of core rod 5; The horizontally disposed loam core fixedly centre of foundary weight 2 is welded with a vertical loam core positioning sleeve 3 that arranges; Loam core fixedly foundary weight 2 is vertical with rising head case foundary weight 1, and loam core fixedly foundary weight 2 is pressed in above two rising head case foundary weight 1, and loam core positioning sleeve 3 is set on the core rod 5; Rising head case foundary weight 1 fixedly is connected by locking constituent element 6 between the foundary weight 2 with the loam core; Adjustment screw 4 is installed in loam core positioning sleeve 3 sides.
It is basic impetus that fixture of the present invention is utilized FPP screw die mould decorative cover, with two rising head case foundary weight-core rod-loam cores fixedly foundary weight-devices such as loam core trimming bolt be coupled to each other, all adopt profiled member and standard component, improve the utilization rate of material, improved simultaneously operating efficiency.
