2. Description of the Related Art Oil seals are press-fitted into bearings of rotating equipment such as vehicle transmissions and differentials to prevent foreign matter from entering the bearings and to prevent lubricant from leaking.

Furthermore, in the cylinder block of a vehicle engine, a sealing plug is press-fitted into a hole opened in the cylinder block for convenience of processing to close the hole.

These parts, such as oil seals and sealing plugs, are generally press-fitted automatically into part press-fit portions of mating members using cylinders.

Conventionally, as shown in Fig. 11, a part press-fitting device that automatically press-fits parts such as oil seals and sealing plugs into a part press-fitting part of a mating member press-fits an oil seal into a bearing part of a rotating equipment. A parts press-in device is being considered.

In FIG. 11, reference numeral 50 denotes an oil seal which is a part to be press-fitted, numeral 51 denotes an engine part which is a mating member into which this oil seal 50 is press-fitted, numeral 52 denotes the oil seal 50, and an oil seal of the engine part 51. This is a press-fitting device for press-fitting parts into the press-fitting portion 51a.

This component press-fitting device 52 includes the oil seal 5
0, and a component press-fitting means 5 for press-fitting into the oil seal press-fitting portion 51a of the engine component 51;
3, a component supply device 54 that supplies oil seals 50 to the press-fitting operation area of this component press-fitting means 53, and a component supply magazine 55 that sequentially supplies oil seals 50 to this component supply device 54.

Then, the component conveyance bar 56 of the component supply device 54 receives the oil seal 50 from the component supply magazine 55 into the component storage recess 56a formed in the component conveyance bar 56, and transfers the oil seal 50 to the conveyance cylinder 5.
When this oil seal 50 is pushed in the direction of arrow P by 7 and fed directly below the press-fitting head 58 of the component press-fitting means 53, this press-fitting head 58 is lowered in the direction of arrow Q by the press-fitting cylinder 59. .

The press-fitting head 58 stops at a position where the component holding portion 58a at its tip enters inside the oil seal 50 to which it has been fed.

At this time, the press-fit head 58 holds the oil seal 50 with the component holding portion 58a at its tip, and after this, the press-fit head 58 once moves in the direction of arrow R while holding the oil seal 50. Rise and retreat, returning to the original position.

When the press-fitting head 58 rises while holding the oil seal 50, the component transport bar 56 of the component supply device 54 retreats in the direction of arrow S and returns to its original position, and the next oil is removed from the component supply magazine 55. Receive sticker 50.

When the component conveying bar 56 of the component supply device 54 retreats, the press-fitting head 5 of the component press-fitting means 53
8 descends again in the direction of arrow T, and pushes the oil seal 50 being held into the oil seal press-fitting portion 51a of the engine component 51 to fit it.

When the component press-fitting means 53 finishes press-fitting the oil seal 50 into the front retainer 51, the press-fitting head 58 of the component press-fitting means 53 moves in the direction of the arrow U again.
It ascends and retreats in the direction of , returns to its original position, and one cycle of the press-fitting operation is completed.

[Problem that the invention attempts to solve]

However, the component feeding device 54 of the conventional component press-fitting device 52 receives the oil seal 50 in a component-accommodating recess 56a having a bottom through which the oil seal 50 cannot pass.
After holding the oil seal 50 during the descent, it is impossible to continue the descent without stopping.

Therefore, the press-fit head 58 is stopped once at the position where the oil seal 50 is held, and after holding the oil seal 50, it is raised once, and after the component conveyance bar 56 is retreated, the press-fit head 58 is moved again. 56 must be lowered for press fitting.

Therefore, the press-fitting process takes time, and
A complicated control circuit was required to ensure positioning accuracy at a predetermined position and to perform two-stage operation.

Furthermore, depending on the temperature conditions of the pressure fluid supplied to the press-fit cylinder 59, the press-fit cylinder 59
The movement stroke of the press-fitting head 56 driven by the press-fitting head 56 may change, and its stopping position may become incorrect.

If the movement stroke of the press-fitting head 56 is larger than a specified value, there is a problem in that the press-fitting head 56 deforms the component conveying bar 56, thereby hindering subsequent operations.

On the other hand, if the movement stroke of the press-fitting head 56 is smaller than the specified value, the oil seal 50 will not be held in the correct position by the press-fitting head 56, and may fall midway or be press-fitted at an angle, resulting in rework in subsequent processes. There was a problem that the work took time.

Therefore, an object of the present invention is to enable a component to be reliably press-fitted into a component press-fitting portion of a mating member by one downward movement of the press-fitting head of a component press-fitting device.

[Means for solving problems]

Therefore, the present invention is characterized in that after a component is pressed and held by the press-fitting head, the press-fitting head is moved toward the component press-fitting portion of the mating member.
