Description
Technical Field
The utility model relates to the technical field of engine assembly equipment, in particular to a front oil seal pressing-in jig of a TNGA assembly line.
Background
The oil blanket station of impressing before the TNGA engine, new form engine and engine chain cover and oil blanket form size in the past are different, adopt traditional mode of impressing to easily lead to the problem that chain cover warp and oil blanket are damaged, and the operation is gone off to the online preceding current oil blanket machine of impressing, and the chain cover can only be impressed at the operation bench by hand, because TNGA engine part article particularity, the thin rigidity of chain cover is poor, preceding oil blanket size leads to impressing in-process chain cover warp, preceding oil blanket is damaged greatly.
SUMMERY OF THE UTILITY MODEL
In order to effectively solve the problems in the background art, the utility model provides a front oil seal pressing jig for an NGA assembly line, and the specific technical scheme is as follows;
the utility model provides a tool is impressed to oil blanket before TNGA assembly line which characterized in that: the device comprises a pressure head, a body, a bearing, an isolation pad, a round nut and a central screw rod; the front end of center lead screw be equipped with bent axle central screw hole complex screw, center lead screw passes the body, the pressure head cover the front end of center lead screw and with the body passes through bolt fixed connection, the center lead screw passes through the bearing is installed this is internal, and center lead screw ring week integrated into one piece has the baffle, and the baffle is with bearing axial fixity, round nut threaded connection is in on the center lead screw and compress tightly the isolation pad, the isolation pad is sealed the bearing at this internal.
Preferably, the two bearings are separated by a spacer sleeve sleeved on the central screw rod.
Preferably, the tail end of the central screw rod is provided with a nylon cushion.
Preferably, the ram has an inner diameter greater than the outer diameter of the bearing.
Compared with the prior art, the utility model has the beneficial effects that: this tool passes through the pressure head and the combination of central lead screw to use servo electric spanner to impress preceding oil blanket through screwing up the central lead screw and cover the chain, thoroughly solved the deformation and the oil blanket damaged problem that the chain cover impresses under the line.
Drawings

fig. 2 is a sectional view taken along a-a in fig. 1.
Detailed Description
The following detailed description of the preferred embodiments will be made with reference to the accompanying drawings. As shown in fig. 1-2, a TNGA assembly line front oil seal press-in jig comprises a press head 1, a body 2, a bearing 3, an isolation pad 4, a round nut 5 and a central screw rod 6; the front end of center lead screw be equipped with bent axle central screw hole complex screw 7, center lead screw passes the body, the pressure head cover the front end of center lead screw and with the body passes through bolt fixed connection, the center lead screw passes through the bearing is installed this is internal, and center lead screw ring week integrated into one piece has baffle 8, and the baffle is with bearing axial fixity, round nut threaded connection is in on the center lead screw and compress tightly the isolation pad, the isolation pad is sealed the bearing at this internal, and center lead screw rotates for body and pressure head. The brand-new jig that impresses utilizes bent axle centre bore screw thread, relies on the central lead screw of jig to twist the bent axle centre bore, drives the preceding oil blanket through the anterior pressure head of jig and impresses in the chain cover, and this jig can be impressed after engine chain cover has been assembled, has thoroughly solved the deformation and the oil blanket damage that the chain cover impressed under on line.
In order to make the rotation of the central screw rod more stable, the two bearings are separated by an isolating sleeve 9 sleeved on the central screw rod.
In order to fix the central screw rod on the servo electric wrench, the tail end of the central screw rod is provided with a nylon pad 10. Is tightly fixed with the servo electric wrench.
In the utility model, the inner diameter of the pressure head is larger than the outer diameter of the bearing. The pressure head can be in contact fit with the front oil seal to press the front oil seal into the chain cover.
The device is matched with a servo electric wrench for use, the tail end of the central screw rod is fixed on the servo electric wrench, the central screw rod of the jig is screwed into the central hole of the crankshaft, and the front oil seal is driven by the pressure head at the front part of the jig to be pressed into the chain cover.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
