Abstract
The utility model relates to a crushing device for coconuts, which is composed of a hub bowl and a hub core. The hub bowl is in the shape of a bowl. The bottom center of the hub bowl is provided with a penetrating central hole. The hub core is tubular. One end of the hub core is connected with the central hole of the hub bowl. The hub core is laterally provided with a penetrating crankshaft lock hole. The connection of the hub core and the hub bowl can be riveted joint and welded. The bottom of the hub bowl is a plane surface or a curved surface. Because a shaft hub is composed of the hub bowl and the hub core, the hub bowl can be made by punching process. The hub core adopts standard tubes and then adopts processes such as riveted joint connection, welded connection, etc. The utility model has the advantages of replacement of integral shaft hubs (castings), improvement of processes, enhancement of material utilization and reduction of cost.
Description
The utility model relates to a kind of breaker that is used for coconut.
Device for cracking coconut is the core component of coconut, utilizes cutter tooth on the device for cracking coconut to dig into coconut meat thread and collects shredded coconut meat and the Coconut Juice dig by the cover that gathers materials, to reach the purpose of processing coconut.
Existing device for cracking coconut mostly is a solid, be linked to be an outer surface by identical hemisphere in bottom surface and cylinder and evenly be covered with subtriangular little cutter tooth, but whole solid outer surface need be used machined into, and efficient is lower.And its integral body is solid, waste material, manufacturing cost height.The applicant provides a kind of in the CN2174853Y patent can eliminate dead angle, in light weight, cost is low, processing is easy, fastening performance is good open-core type device for cracking coconut.It comprises housing and propeller boss, and housing is a hollow body of forming one by the hemisphere sphere of same bottom surface and cylinder, and housing outer surface is the cutter tooth shape.Propeller boss is the different two-part cylinder of bottom surface diameter, the bigger one section cylinder of its bottom surface diameter is coated by the column part of housing, and one section less cylinder of bottom surface diameter is provided with from lateral surface and connects to the hole of propeller boss center hole, uses screw lock later on so that insert motor crankshaft.Establish fastening load mould at housing and propeller boss covered section, generally adopt 3 load moulds fastening.Because propeller boss is the different two-part cylinder of bottom surface diameter, therefore need to adopt technologies such as casting, cost height, man-hour are long.
The purpose of this utility model is to provide a kind of propeller boss that is used for the open-core type device for cracking coconut, and it has alleviated the weight of device for cracking coconut, processes easyly, can improve work efficiency, saves material, and greatly reduces manufacturing cost.
The utility model is made up of hub bowl and hub core, and the hub bowl is bowl-shape, and through hole is established at hub bowl bottom center, claim hub bowl mesopore, the hub core is a tubulose, and an end of hub core is connected with hub bowl mesopore, side at the hub core is established through hole, claims the arbor lockhole, so that motor crankshaft is used screw lock after inserting hub core die.
The hub core can adopt riveted joint with being connected of hub bowl, welds or is spirally connected etc.The hub bowl bottom can be the plane or the conical surface, arbitrary surfaces such as sphere.
Owing to adopt and form propeller boss by hub bowl and hub core two parts, therefore the hub bowl can utilize Sheet Metal Forming Technology to make, the hub core adopts standard tubing, adopt riveted joint again, technologies such as welding are connected the hub bowl with the hub core, replace integral type propeller boss (foundry goods), have obviously improved technology, improve stock utilization and production efficiency, reduced cost.
Fig. 1 adopts the structural representation of riveting process for the utility model.
Fig. 2 adopts the structural representation of welding procedure for the utility model.
Fig. 3 establishes the structural representation of tongue piece for the hub bowl.
Fig. 4 establishes the structural representation of notch for the hub core.
Fig. 5 establishes the structural representation of notch for the hub bowl.
Embodiment 1: as shown in Figure 1, the utility model is made up of hub bowl 1 and hub core 2.Hub bowl 1 is bowl-shape, and hub bowl bottom 11 is the curved surface shape, and the hub bowl mesopore 12 of perforation is established at its center.Hub core 2 is a tubulose, and it is fastening that an end of hub core 2 and hub bowl mesopore 12 are done the flange riveted.Establish the arbor lockhole 21 of perforation at the side of hub core 2.
Embodiment 2: as shown in Figure 2, the bottom 11 of hub bowl 1 is plane, and an end of hub core 2 inserts hub bowl mesopore 12, and both are fastening with hub bowl 1 and hub core 2 with welding procedure.
If it is fastening to adopt riveted joint to adopt welding to carry out again between hub bowl 1 and the hub core 2, the quality of propeller boss can be better so.
Embodiment 3: as Fig. 3, shown in 4, for improving the ability of the transmission moment of torsion that riveted connects, the tab 13 of the arbitrary shape of at least 1 protrusion can be set at hub bowl mesopore 12 places of hub bowl bottom 11 in case of necessity, this link at hub core 2 is also established corresponding notch 22, add man-hour with flange riveting jail again after hub core 2 and 1 assembling of hub bowl, or welding.Referring to Fig. 5, also can establish the notch 14 of at least 1 arbitrary shape at hub bowl mesopore 12 places of hub bowl bottom 11, like this, when after the assembling of hub bowl and hub core during with hub core flange riveted, because the hub core material produces local plastic deformation and embeds in the notch 14 of hub bowl, thereby improved the ability of transmitting moment of torsion.
Claims (5)
