Technical Field

The invention relates to the technical field of breather valve assembly, in particular to an automatic breather valve assembly machine.

Background

The breather valve is a breather valve for communicating with air in the hydraulic tank, and is usually mounted on the tank to ensure that the air pressure in the tank is stable when the hydraulic oil is pumped out of the tank. As shown in figure 1, the breather valve generally comprises a mounting seat, an exhaust valve rod, a large spring, a valve plate, a small pressing plate, a small sealing gasket, a protective cover plate, a locknut, a small spring, a positioning seat, a countersunk head screw and other main components.

Generally speaking, the breather valve product basically comprises a basal body, a sealing and positioning assembly, an anti-loosening assembly, a spring assembly and a fixing assembly; the base body is provided with a mounting seat, an exhaust valve rod, a large spring and a valve plate; the sealing and positioning assembly is of a sheet-shaped structure with a central matching hole, at least one sheet, and is sleeved on the exhaust valve rod, as in the breather valve shown in fig. 1, and comprises a small pressing plate, a small sealing gasket and a protective cover plate; the anti-loosening component can be an anti-loosening nut, and is sleeved on the exhaust valve rod after the sealing and positioning component is assembled and locked to a designated position; the spring assembly is sleeved on the exhaust valve rod, the spring assembly is a small spring, the diameter of the small spring is larger than that of the small spring, and an acting end of the spring assembly is propped against the outward side of the sealing positioning assembly; the fixing assembly is a part for fixing the assembly after the assembly of the assemblies is completed, the fixing assembly can be a positioning seat and a countersunk head screw, and the mounting seat is provided with a flange mounting hole corresponding to the positioning seat.

In the prior art, the assembly of the above components is usually completed by adopting manual operation, and a plurality of manual assembly lines are generally required to be subjected to the following procedures to complete the assembly of the breather valve:

1. in the first procedure, assembling a matrix, and manually installing an exhaust valve rod, a large spring and a valve plate on a mounting seat to form the matrix;

2. in the second procedure, the small pressing plate, the small sealing gasket and the protective cover plate are respectively arranged on the exhaust valve rod of the base body by manpower, and the assembly fit clearance between the small sealing gasket and the exhaust valve rod is relatively tight, but the position of the exhaust valve rod is accurate when the assembly is required to be ensured;

3. in the third procedure, the locknut is manually screwed on the exhaust valve rod and locked at a designated position;

4. in the fourth step, a small spring is sleeved on the exhaust valve rod manually;

5. in the fifth step, the positioning seat is manually placed at the position of the mounting flange hole corresponding to the mounting seat, and then the countersunk head screw is used for locking the positioning seat and the base body.

As can be seen from the above steps, the conventional breather valve assembling process has complex steps, requires a plurality of persons to cooperatively operate, consumes high labor hours, and meanwhile, the inventor also finds that the conventional method has at least the following problems during manual assembly:

1. In the whole assembly process, after the first working procedure is completed, the mounting seat, the exhaust valve rod, the large spring and the valve plate form a matrix, the central position of the exhaust valve rod in the matrix is the key point of the matrix, the exhaust valve rod is required to be centered in the subsequent working procedure, and the manual operation is based on the experience of workers and is easy to make mistakes;

2. in the second procedure, the placement of the small pressing plate, the small sealing gasket and the protective cover plate is required in sequence and is assembled, and because the small pressing plate, the small sealing gasket and the protective cover plate are small in size and close in shape, the problem of wrong assembly and missing assembly easily occurs when the small pressing plate, the small sealing gasket and the protective cover plate are manually taken and placed;

3. because the assembly requirement of breather valve is high, need carry out the training to the workman and just can operate, if have several product models, just need carry out the training to the workman several times and put on duty, with high costs, because workman's proficiency is different, the effect of assembling out is also uneven simultaneously.

In view of this, it is an object of the present invention to solve the above problems of the prior art.
