Abstract
The invention discloses a farming machine transmission case flange plate which comprises a flange plate body with a shaft hole, wherein the flange plate body is an aluminum alloy casting, an installing hole is installed on the aluminum in a loose core mode, and the wall thickness of the aluminum alloy casting is 4 mm. The farming machine transmission case flange plate is simple in structure, low in weight and cost, high in production efficient and small in subsequent processing amount.
Description
Technical field
The present invention relates to a kind of flange plate of agricultural ploughing machine transmission case, belong to the agro-farming mechanical field.
Background technique
Existing agricultural ploughing machine flange plate is all to select cast iron flange or sand casting flange plate, its shortcoming is: at first, because the flange plate size does not have versatility, make the assembling difficulty, and cast iron density is 7.8(g/cc), make flange plate be assembled to that in machinery, weight is unfavorable for more greatly mechanical light-weight design; Secondly, the flange plate of sand casting exists manufacturing efficiency low (every needs 7-8 minute), yield poorly and machining allowance large, precision is low, scaling loss is many, production environment is abominable, following process is numerous and diverse, outward appearance such as slightly makes at the defective.
Summary of the invention
The invention is intended to provide a kind of lighter weight, agricultural ploughing machine transmission case flange plate that the following process amount is little.
Purpose of the present invention can reach by following measures: a kind of agricultural ploughing machine transmission case flange plate, comprise the flange plate body, the flange plate body is with axis hole, and described flange plate body is aluminum alloy die casting, the described aluminum alloy die casting formation mounting hole of loosing core, this aluminum alloy die casting wall thickness is 4mm.
The technique scheme difference with the prior art is: at first, change cast iron flange into aluminum alloy die casting, alleviated the weight of flange plate, be convenient to the die casting manufacturing; Secondly, the mounting hole of directly loosing core in die casting has reduced drilling operating, and follow-up needs tapping thread to get final product, reduced the following process amount; Secondly, the aluminum alloy die casting wall thickness is 4mm, has saved raw material, has further alleviated weight.
The present invention is simple in structure, weight is light, manufacturing efficiency is high, the following process amount is little.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments:
Fig. 1 is agricultural ploughing machine transmission case flange plate embodiment's of the present invention structural representation.
Embodiment
With reference to Fig. 1, a kind of agricultural ploughing machine transmission case flange plate comprises the flange plate body, and this flange plate body is aluminum alloy die casting, and the aluminum alloy die casting center is axis hole, this axis hole periphery formation mounting hole of loosing core, and this aluminum alloy die casting wall thickness is 4mm.
The present invention has reduced the weight of flange plate body from both direction, and the one, the improvement of raw material makes iron charge into the aluminium alloy stock of lighter weight, and the 2nd, reduced the wall thickness of flange plate, therefore, flange plate is assembled to and is conducive to mechanical light-weight design in machinery.The present invention is in order to have reduced the subsequent process steps of flange plate, and the formation mounting hole of loosing core only need to can form tapped hole to the mounting hole tapping during flange plate fine finishing.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from structure of the present invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
Claims (1)
1. an agricultural ploughing machine transmission case flange plate, comprise the flange plate body, and the flange plate body is characterized in that with axis hole: described flange plate body is aluminum alloy die casting, the described aluminum alloy die casting formation mounting hole of loosing core, and this aluminum alloy die casting wall thickness is 4mm.
