Abstract
The invention discloses an air tightness test tool. The air tightness test tool comprises an air chamber, a fixing flange, glands and fixed connection mechanisms. The air chamber comprises an air chamber wall and connecting flanges, wherein the air chamber wall is cylindrical, and the left end and the right end of the air chamber wall are provided with the left connecting flange and the right connecting flange respectively. The glands comprise the left gland and the right gland, and the left gland and the right gland are arranged on the left side of the left connecting flange and the right side of the right connecting flange respectively. Workpiece fixing positions are reserved between the left connecting flange and the left gland and between the right connecting flange and the right gland respectively, and workpieces are arranged at the workpiece fixing positions. The left connecting flange and the left gland are connected through one fixed connection mechanism, and the right connecting flange and the right gland are connected through the other fixed connection mechanism. The left gland and the right gland are respectively provided with a gland through hole. The air chamber wall is further provided with the fixing flange, and the fixing flange is provided with fixing holes. The air tightness test tool is simple in structure and is assembled through common parts and equipment, and therefore the production cost is saved. Besides, an air tightness test can be carried out on the two workpieces at the same time, and therefore the production efficiency is improved.
Description
Technical field
The present invention relates to a kind of test unit field, specifically a kind of tightness test frock.
Background technology
Along with the evolution of producing, the weeding out the old and bring forth the new of new product, test unit field also needs new product following to update, but the testing equipment complex structure of tightness test, complex operation step, production cost is high, and the air-tight test that at every turn can only realize a product, production efficiency is low.
Summary of the invention
The object of this invention is to provide a kind of tightness test frock.
It is complicated that the present invention will solve existing tightness test device structure, complex operation, and production cost is high, can only realize the impermeability experiment of a product, the problem that production efficiency is low at every turn.
Technical scheme of the present invention is: a kind of tightness test frock, comprise air chamber, mounting flange, gland be fixedly connected with mechanism, described air chamber comprises air chamber wall and joint flange, described air chamber wall is cylindric, the two ends, left and right of described air chamber wall are respectively equipped with left joint flange and right joint flange, described gland comprises left gland and right gland, be located at respectively the left side of left joint flange and the right side of right joint flange, between described left joint flange and left gland, between right joint flange and right gland, it is workpiece fixed bit, workpiece is located on workpiece fixed bit, between described left joint flange and left gland, between right joint flange and right gland, by being fixedly connected with mechanism, connect, on described left gland and right gland, be equipped with gland through hole, on described air chamber wall, be also provided with a mounting flange, described mounting flange is provided with fixed orifice.
Between described air chamber wall and left joint flange, between air chamber wall and right joint flange, by being welded and fixed, between described workpiece and left gland, right gland, left joint flange and right joint flange, be equipped with O RunddichtringO.
The described mechanism that is fixedly connected with comprises bolt, nut and plain washer.
Beneficial effect of the present invention is: the present invention is simple in structure, adopts common pieces of equipment to assemble, and has saved production cost, and can to two workpiece, carry out air-tight test simultaneously, has improved production efficiency.
