Description

Water sealing stationary ring subgroup assembling machine

Technical field

The utility model relates to a kind of assembly equipment, specifically is a kind of water sealing stationary ring subgroup assembling machine.

Background technology

At present, the light water seal structure is mainly used in auto industry as shown in Figure 1, and it generally comprises moving ring assembly and static components, through the flange assembly technology the two is linked up, and becomes an integral body; Moving ring assembly comprises axle sleeve 1, rubber seal 9 and rotating ring friction pair 2; Axle sleeve 1 utilizes the interference fit of rubber seal 9 to play sealing function with rotating ring friction pair 2; Static components comprises fixed housing, spring, two metal tight loops, stationary ring friction pair and elastic supports; Make the boss interference fit of elastic support lower end and fixed housing by a metal tight loop; Make elastic support upper end and stationary ring friction pair interference fit by another metal tight loop; Spring is enclosed within on two metal tight loops.

The water sealing stationary ring assembly of said structure is when assembling, and shown in Fig. 2 a～2g, because the characteristic of its structure, each part assemble sequence has also just been decided: the first step, and the metal tight loop faced down is set to the elastic support lower end; In second step, the elastic support that the metal tight loop is housed is set on the boss of fixed housing; The 3rd step, firmly depress the P face of metal tight loop, the two couples together to make the metal tight loop rely on the magnitude of interference and elastic support, fixed housing; The 4th step, pack into successively again spring and metal tight loop, metal tight loop face should be up herein; The 5th step, firmly depress the H face of metal tight loop, make the upper end of elastic support exceed the metal tight loop fully, again the stationary ring friction pair with the supine position of R, put into the upper end of elastic support; The 6th step, firmly depress the R face of stationary ring friction pair, the two couples together to make the stationary ring friction pair rely on the magnitude of interference and metal tight loop, elastic support, unclamps static components at last, and whole assembling is finished.

In above-mentioned steps, the 4th step, the 5th step and the 6th step are committed steps, also are the most difficult dress parts of whole water sealing stationary ring assembly, and prior art water sealing stationary ring assembly hand assembled has been brought many inconvenience to the operative employee, mainly has following shortcoming:

1, in the 4th step, spring itself has certain free height, certain compression is also arranged in assembling, the material of elastic support own is a flexible material, compressible also scalable, spring in the assembling can drop out the metal tight loop bullet that is enclosed within above the elastic support come automatically, can not reach the effect of expection assembling.

2, in the 5th step, when assembling stationary ring friction pair, want earlier spring to be depressed, reinstall the stationary ring friction pair, owing to be subjected to the restriction of fixed housing size, can't finish with assembler's hand during pressing spring, can only depress spring earlier by means of a kind of special instrument and put into the stationary ring friction pair again, assembling is very inconvenient like this.

3, in the 6th step, when firmly depressing the stationary ring friction pair, firmly size is wanted suitably and evenly, otherwise tilt phenomenon can appear in the stationary ring friction pair after the installation, therefore, to assembler's technology have relatively high expectations and also efficiency of assembling low.

The hand assembled method difficulty height of above prior art in sum, efficiency of assembling is low, and assembly precision is poor, complex operation.

The utility model content

The technical problems to be solved in the utility model is, a kind of assembly precision height, efficient height, water sealing stationary ring subgroup assembling machine simple to operation are provided.

The technical solution of the utility model is that a kind of assembly machine with following structure is provided: mainly form by base plate, workbench, guide rail, indenter device I, presser device, slide carriage device and with the gripper that presser device and slide carriage device are used; Described workbench is installed in above the base plate, described indenter device I is installed in an end of base plate, described presser device is located at indenter device I below and is installed on the base plate, the axis of the pressure head I of the axis of the through hole of its presser device and indenter device I is on same straight line, the minimum diameter of described through hole is greater than the external diameter of pressure head I, described slide carriage device and the guide rail sliding fit that is installed on the base plate.

After adopting above water seal assembly machine, the utility model compared with prior art has the following advantages:

1, owing to cooperation by gripper and slide carriage device, put into spring and metal tight loop from the guideway of gripper, the length of guideway is greater than the length of spring, and by the pressing plates metal tight loop and the spring of presser device, so spring can not drop out metal tight loop bullet come, and can reach the requirement of assembling.

2, because the pressing plate of presser device directly compresses metal tight loop and spring by the guideway of gripper, gripper can shrink under the effect of external force automatically then, then take out gripper and put into the stationary ring friction pair again, need not come holddown spring, so it is very convenient to put into the stationary ring friction pair by other special instruments.

3, because the pressure head by indenter device II compresses the metal tight loop, and pressure head provides pressure by cylinder, with dynamic balance and evenly, so the assembly precision height.

As improvement, because indenter device I, can overcome the magnitude of interference of elastic support body upper end by being used jointly with presser device and slide carriage device, the stationary ring pair of friction components are pressed on the metal tight loop accurately, very convenient.

As improvement, owing to also be provided with the discharging cylinder, after being finished, the static components assembling from the slide carriage device, ejects, convenient, improved efficiency of assembling.
