Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an oil seal supply device that automatically supplies oil seals one by one to a predetermined take-out position with oil applied to the inner peripheral surface.

(Prior art) Conventionally, when press-fitting an oil seal into the shaft member insertion opening of a transmission case or other workpiece, oil was manually applied to the inner circumferential surface of the oil seal, and the oil was placed in a press-fitting jig and the oil seal was pressed into the shaft member insertion hole of a transmission case or other workpiece. The oil seal is press-fitted using a press-fitting jig.

(Problems to be solved by the invention) It is inefficient to manually apply oil to the oil seal one by one and set it in the press-fitting jig, as in the above-mentioned conventional technology. It is desired to be able to automatically supply oil seals one by one to a predetermined removal position with oil applied to their inner circumferential surfaces so that the oil seals can be received.

Furthermore, if the oil seal is supplied to the take-out position with the front and back facing reversed, the oil seal will be press-fitted into the workpiece insertion opening in the opposite direction, so it is desirable to be able to detect the front and back of the oil seal.

An object of the present invention is to provide a supply device that satisfies such demands.

(Means for Solving Problems) In order to achieve the above object, the present invention provides an oil seal supply device that supplies oil seals one by one to a predetermined removal position with oil applied to the inner peripheral surface. The jig table has a vertically long first guide hole through which the oil seals are inserted in a line in the radial direction through the upper insertion port, and a first guide hole on the side of the first guide hole having an extraction port on the lower side. a second guide hole parallel to the first guide hole, and a horizontal hole spanning the lower side of the first guide hole and the upper side of the second guide hole, and one oil seal is received in the horizontal hole. If the slider is formed with a receiving hole penetrating in the vertical direction, the receiving hole
The receiving position matches the guide hole and the receiving hole matches the second
a support member that is movably inserted into a dispensing position matching the guide hole and removably supports the oil seal dispensed from the slider on the outer peripheral surface below the outlet of the second guide hole;
Further, an oil application rod is provided on the jig stand to be inserted into the inner periphery of the oil seal in the first guide hole and apply oil so that it can move forward and backward toward the oil seal,
A front/back detection rod that can be inserted into the folded portion of the oil seal is provided on the oil applicator rod so as to be freely retractable against a spring, and a detection means for detecting the amount of retraction of the front/back detection rod is provided on the jig stand. It is characterized by

(Function) With the oil seal inserted into the first guide hole, move the oil applicator rod forward to apply oil to the inner peripheral surface of the oil seal, then move the oil applicator rod back and receive the slider from the delivery position. When the receiving hole of the slider matches the first guide hole, the lowermost oil seal falls into the receiving hole under its own weight, and then moves the slider to the dispensing position. According to this, when the oil seal moves in the horizontal hole with the movement of the slider and the receiving hole matches the second guide hole, the oil seal falls in the second guide hole due to its own weight and falls onto the lower support member. Supported by

Next, after removing the Ueno oil seal from the support member, the oil applicator rod is moved forward and the above operation is repeated, thereby automatically supplying the oil seals onto the support member one by one with oil applied to the inner peripheral surface. Ru.

Here, if the back side of the oil seal is facing the oil application rod side with the surface in the folded direction side of the oil seal as the back surface, the front/back detection rod is inserted into the folded part of the oil seal when the oil application rod moves forward, and detects the front/back side. If the rod does not move back relative to the oil application rod and the oil seal is in the opposite direction, the front/back detection rod will not be inserted into the folded part of the oil seal and will come into contact with the end face of the oil seal, preventing it from moving further. is retracted relative to the oil application rod against the spring.

Therefore, the front and back sides of the oil seal can be detected by detecting the amount of retraction of the front and back detection rod using the detection means.
