Two auricles with holes and a positioning pin are arranged on every clamp block and a knife rest is arranged on a clamp block, a boring cutter is also arranged on the knife rest, the two clamp blocks can be locked tightly by the auricle with using a bolt and a nut. The utility model is characterized by simple structure and convenient operation.

Description

A kind of device of restoring oil cylinder gudgeon

Technical field:

The utility model relates to a kind of device of restoring oil cylinder gudgeon.

Background technology:

After the boom cylinder Ear Abrasion of loading machine is excessive, need it is repaired, because this oil cylinder trunnion axis perpendicular to the cylinder barrel axis, after the Ear Abrasion place is carried out built-up welding, can't be processed under the situation of no dedicated tool with existing machine tool.The method that adopts is manpower processing at present, uses earlier electric angle grinder roughing, and with bastard file processing, the back processes with smooth file again.The method is required great effort time-consuming and dimensional accuracy is difficult to guarantee.

Summary of the invention:

The purpose of this utility model just provides a kind of device of restoring oil cylinder gudgeon, replaces manpower processing with machining, the not only laborsaving not only requirement that saves time simultaneously but also can guarantee machining accuracy.

To achieve these goals, the utility model adopts following technical scheme:

The utility model comprises two fixture blocks, two fixture blocks are two semicircles that the cover symmetry is cut open, respectively be provided with two auricles with holes and an alignment pin on each fixture block, also be provided with knife rest on a fixture block therein, boring cutter also is installed on the knife rest, and two fixture blocks can be locked by the hole of auricle with screw bolt and nut.

The utlity model has characteristics such as simple in structure, easy to use.

The specific embodiment:

Contrast Fig. 1, Fig. 2 are as can be known, the utility model comprises

fixture block

1 and 2 two fixture blocks of fixture block, two fixture blocks are two semicircles that the cover symmetry is cut open, respectively be provided with two auricles with holes 9 and an alignment pin 8 on each fixture block, on fixture block 2, also be provided with knife rest 3, boring cutter 4 also is installed on the knife rest 3, and fixture block 1 and fixture block 2 can be locked by the hole on the auricle 9 with bolt 5 and nut 6.

Contrast Fig. 3 as can be known, operation principle of the present utility model is as follows: earlier oil cylinder 12 is placed on the vertical drill workbench, be clamped on the workbench behind the axis centering with gudgeon 11, be stuck on the vertical drill main shaft 10 with fixture block 1 and fixture block 2 again, make alignment pin 8 enter main shaft diameter to slotted hole in, two fixture blocks are tightened by auricle 9 with bolt 5 and nut 6, fixture block is locked on the main shaft, on knife rest 3, load onto boring cutter 4, fasten boring cutter with screw 7, the starting drilling machine drives the boring cutter assembly by the cutting direction rotary main shaft and rotates, and main shaft moves down and can carry out machining to gudgeon 11.

Claims
