Description

Apparatus for fixing crank on deburring}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crank fixing device during deburring, and more particularly, to form an oil hole using a drill in the crank during a crank manufacturing process, for fixing the crank not to flow in order to deburr unnecessary parts generated in the oil hole. As a device, it is possible to improve productivity and economy by fixing the crank not to flow to debur the crank during the crank manufacturing process and reducing the damage of the deburring device generated by the crank flow during deburring, thereby preventing interruption of the production line. It relates to a crank holding device during deburring.

In general, the crank is supported by the main bearing installed in the crankcase, and converts the linear power of the piston obtained by the expansion stroke of each cylinder into the rotational force through the connecting rod, and also generates the power continuously by moving the piston on the other stroke. The most important role is to play.

The crank is generally made of an integral structure, and is composed of a crank pin, a crank arm, and a crank journal. In addition, a balancing weight is installed on the crank arm to maintain rotational balance.

In addition, at the rear of the crank there is a housing which engages a flange for mounting the flywheel and a pilot bearing for supporting the clutch shaft tip.

At the front end, a timing gear or timing chain sprocket for driving the camshaft, a crank pulley for driving a water pump, an alternator, and the like can be provided.

Other cranks have oil holes for supplying oil to connecting rods, bearings, piston pins and bearings, and some of the oil supplied to the main bearings is pumped through the oil holes.

In addition, in order to prevent the oil in the crankcase from leaking to the outside at the front and rear ends of the crank, an oil seal is used on the outside of the front and rear bearings. There is also.

When the oil hole is formed using a drill in the crank manufacturing step, debris is performed to remove foreign substances such as chips remaining in the oil hole due to the drilling operation.

However, when the deburring operation should be fixed so that the crank does not flow, there was a problem that the production line is stopped because the deburring device is damaged because these equipments do not perform their role.

The present invention is to solve the above problems, during the crank manufacturing process, the crank is fixed so as not to flow in order to deburring the crank, reducing the damage of the deburring device generated by the crank flow during deburring to prevent interruption of the production line In order to improve productivity and economics, it is intended to provide a crank holder during deburring.

This invention comprises a crank formed of a crank front and a crank rear; A center clamp comprising a center clamp fixing end for fixing an end of the crankfront and a center clamp pneumatic cylinder supporting the center clamp fixing end from the rear; A support end for supporting a lower portion of the crank center, a weight balance clamp pneumatic cylinder positioned behind the support end, an operating end fastened to the weight balance clamp pneumatic cylinder, and configured to vertically flow, and a center of which is hinged to the support end A weight balance clamp having one side coupled to the operating end and a rotating end having a weight balance fixing end configured to support a central upper portion of the crank; A rear clamp comprising a rear clamp fixing end supporting an upper end of the crank rear, a V block supporting a lower end of the crank rear, and a rear clamp pneumatic cylinder for raising the V block; It is achieved by a rear support end positioned between the center clamp and the weight balance clamp to support the lower part of the crank.

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

A crank 100 formed of a crankfront 110 and a crank rear 120; A center clamp (200) comprising a center clamp fixing end (210) for fixing an end of the crankfront (110), and a center clamp pneumatic cylinder (220) for supporting the center clamp fixing end (210) from the rear; It is fastened to the support end 310 for supporting the central lower portion of the crank 100, the weight balance clamp pneumatic cylinder 330 located behind the support end 310, and the weight balance clamp pneumatic cylinder 330 The operating end 340 is formed to be able to flow up and down, the center is hinged to the support end 310, one side is hinged to the operating end 340 and the other side supports the upper portion of the center of the crank 100 A weight balance clamp 300 formed of a rotating end 320 having a weight balance fixing end 350; Rear clamp fixing end 410 for supporting the upper end of the crank rear 120, V block 420 for supporting the lower end of the crank rear 120, Rear clamp pneumatic for raising the V block 420 A rear clamp 400 formed of a cylinder 430; Technical features of the present invention include a rear support end 500 positioned between the center clamp 200 and the weight balance clamp 300 to support the bottom of the crank 100.

Hereinafter, the operation of the present invention will be described with reference to FIGS. 1 to 5.

As shown in FIG. 1, a center clamp 200 is provided in a direction in which the crank front 110 is formed around the crank 100, and a weight balance clamp 300 is provided in the center of the crank 100. A rear clamp 400 is provided in a direction in which the 120 is formed, and a rear support end 500 is formed between the center clamp 200 and the weight balance clamp 300.
