Component fixing device for connecting rod using hydraulic fixtures {Hydrostatic fixture device for connecting rod}

The present invention relates to a device for fixing a connecting rod using a hydraulic fixture, and more particularly, to a fixing device for fixing a connecting rod on a machining table when machining a connecting rod, which is a component used for assembling a medium engine of a ship. It is about.

The connecting rod is subjected to the final finishing work before the actual assembly of the engine. In the case of the connecting rod, which is usually used for a medium engine, as shown in FIG. 1, the shaft (a) is a component drawing, a bearing cover ( bearing cover) (b) drawing, bearing body (c) drawing, cut and separated into three parts again, these temporary parts, such as face grinding, milling, boring and taps are performed.

In general, the machining work for each part of the connecting rod uses automation equipment such as a machining center.

That is, the fixing device according to the present invention will be introduced to use when fixing the position of each part on the machining table (plate) provided in the equipment for the machining operation for each part of the connecting rod.

On the other hand, the present applicant has introduced a fastening device for each part of the connecting rod through the Republic of Korea Utility Model No. 0431065, which is fixed to each of the parts for a large number of connecting rod on one processing table to perform the machining work In order to perform, it introduces the structure that can fix the multi-stage parts not only on the plane of the table but also in the height direction. However, as a means for fixing each part, the operator directly uses a clamp, an adjusting screw, etc., and in order to actually fix the corresponding parts of the connecting rod, a manual manual fastening operation by the operator is required, especially a medium As with the engine, the inconvenience of handling the individual parts of the heavy-duty connecting rod, as well as the series of manual fixing of each part on the machining table, does not reduce the overall machining time. It was.

In addition, even when performing the actual machining work for each of the parts fixed on the machining table with the screw and clamp type fixing device as described above, the machining of the corresponding parts due to the interference of the fixing devices arranged around each part Not only does the work not be carried out uniformly, but it also increases the processing time, such as turning over the part or rotating it and fixing it again. There was a problem that further increases the fatigue.

Therefore, the present invention is to solve the conventional problems as described above, its purpose is simply to fix and dismantle the position without requiring the operator by using hydraulic fasteners for the corresponding parts mounted on the processing table for processing It's about making things work.

In addition, by eliminating the spatial interference between the parts mounted on one machining table and the respective fixing devices, the time required for frequent movement of the parts under machining due to the actual machining operation is reduced, and the overall machining process is performed. It is to provide a device for fixing the parts of the connecting rod using a hydraulic fixture that can shorten the.

The present invention for achieving the above problems and to eliminate the conventional drawbacks in the component fixing device for performing a finishing process for the shaft, the bearing cover and the bearing body which is a part of the connecting rod pre-formed,

A machining table 5 placed in the operating range of the machining machine; One or more mounts (11) (21) (31) fixedly mounted on the processing table to seat the shaft (1), bearing cover (2) and bearing body (3), respectively; The mounting table is characterized in that the driving fixtures 100, 200, 300 for the pressure fixing the upper surface of the corresponding components are installed.

In addition, on the processing table, in order to prevent mutual interference during the machining operation, it may be configured to further include a mounting table (21 ", 31") having a height difference with the other mounting table neighboring.

At this time, the driving fixture provided in the mounting table, the hydraulic cylinder 401 is fixed to the upper surface of the mounting table, to pull out the rod 402 in the vertical direction; The swing cam 403 is coupled to the end of the rod, and rotates in a horizontal direction about the coupling shaft, and presses and fixes the upper surface of the corresponding parts seated on the mounting table.

The present invention from the above means by using the hydraulic fixture used for the hydraulic drive installed on the processing table, by providing a convenience for the fixing operation for fixing the various components and the dismantling operation for dismantling the various components after processing is completed, It is possible to reduce the work time required for the machining process while eliminating the fear of adding excessive fatigue to the worker.

In addition, it is possible to perform simultaneous machining operations on various components seated on one machining table by eliminating spatial interference that may occur between a plurality of components seated on one machining table and various components seated on one machining table. Therefore, the efficiency of a series of machining operations can be greatly improved.

Hereinafter, the embodiment of the present invention will be described in detail with reference to the accompanying drawings.
