Abstract
The utility model relates to the technical field of sewing machines, particularly to a housing structure of a sewing machine head. The utility model overcomes the problems of installation error, narrow using space of an inner chamber, heavy weight and high cost in the prior art. The technical scheme is adopted as follows: the housing structure comprises an upper arm, a stand column, a belt cover and a base plate and is characterized in that the upper arm is formed by two parts, namely, an upper cover body and an upper arm main body at the lower part; and the stand column is formed by an inner column housing and an outer column housing, wherein the upper arm main body, the inner column housing and the base plate form an integrated structure, the upper cover body, the belt cover and the outer column housing form an integrated structure, and the two integrated structures are connected with each other. The housing structure has the advantages of accurate positioning, large using space, good stiffness and low cost.
Description
Technical field
The utility model relates to the Sewing machines equipment technical field, is specifically related to a kind of shell structure of head of sewing machine.
Background technology
The existing sewing machine handpiece case comprises upper arm, column, belt housing and four parts of base plate, wherein upper arm and column are one-step die casting, after in upper arm and column, chipware being installed, the bottom of column and base plate link together by the mode of pin location, bolted, and belt housing is fixed in the assembling of finishing handpiece case on the column.The problem that prior art exists is: 1, alignment error is big: the error when casing cooperates with base plate is big, influences the installation and the action of inner core member; 2, the inner chamber usage space is dwindled: adopt screw fastener, the usage space of having dwindled the handpiece case inner chamber; 3, weight is big, cost is high: owing to all adopt the casting pig casting to form, so handpiece case weight is big, and use is inconvenient, and the cost of raw material is higher; 4, between column and the base plate bonding strength a little less than, and in order to guarantee precision, difficulty is bigger when assembling.
Summary of the invention
The utility model will provide a kind of shell structure of head of sewing machine, to overcome the alignment error that prior art exists, the problem that the inner chamber usage space is dwindled, weight is big and cost is high.
For overcoming the problem that prior art exists, the technical solution of the utility model is: a kind of shell structure of head of sewing machine, comprise upper arm, column, belt housing and base plate, its special character is: described upper arm is made of upper arm main body two parts of upper cover body and bottom, column is made of inner prop shell and column jacket shell, wherein upper arm main body, inner prop shell and base plate are integral structure, and upper cover body, belt housing and column jacket shell are integral structure, and two integral structures connect.
Above-mentioned upper arm main body, inner prop shell and base plate select for use the gray cast iron material one-step casting to finish, and described upper cover body, belt housing and column jacket shell select for use the plastic material one-step casting to finish.
The top of above-mentioned upper arm main body is provided with gusset plate.
Above-mentioned upward gusset plate and upper arm main body select for use the gray cast iron material one-step casting to finish.
The side that above-mentioned inner prop shell is adjacent with the column jacket shell is provided with the side gusset plate.
Above-mentioned side gusset plate and column jacket shell select for use the gray cast iron material one-step casting to finish.
Above-mentioned casting pig is HT200.
Compared with prior art, advantage of the present utility model is as follows:
1, the location accurately: do not need to carry out installations that cooperate of casing and base plate again, also just thoroughly eliminated the alignment error of existence, locate more accurately, the installation of inner body and action obtain correct guarantee;
2, usage space is big: cancelled securing member, keepers such as screw, pin, increased the usage space of chassis cavity;
3, good rigidly: column and base plate adopt disposable casting, and the casing structure rigidity is more stable;
4, cost is low: the material of whole head shell has also been used plastic material in a large number except that adopting casting pig (HT200), saved raw-material cost, simultaneously because of having used plastic material, has therefore saved the application face of this part again, reduces the back trimming cost.
