Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a jig device for roll and spring assembly of an automotive start motor overrunning clutch,

The present invention relates to a motor start motor running run which can assemble a roll and a spring necessary for an overrunning clutch coupled to an automotive start motor more quickly and precisely, To a jig device for roll and spring assembly of a clinch.

An overrunning clutch is normally required for transmitting the power of a starter installed in a start motor of an automobile to the engine and for protecting the starter by interrupting the power from the engine in an overrun.

Overrunning clutches for automobiles can be classified into roller type, sprag type, multi-plate type clutch type according to the type of parts to be built in and clutch operation principle.

In particular, in the case of a roller type overrunning clutch, as shown in the figure, in a plurality of roll storage grooves and a plurality of roll grooves formed in the clutch body at a constant constant angle,

When the rotary shaft is rotated in one direction, it is avoided in the roll receiving groove larger than the diameter of the roll so as to allow free rotation with respect to the rotary shaft. However, when the rotary shaft rotates in the opposite direction, the roll is moved and strongly pinched toward the narrow groove, A roll capable of stopping the clutch operation; A spring for applying an elastic force to the movable roll so that the movable roll can be returned to its original position; A plurality of rolls + spring sets including a plurality of rolls are assembled at constant angular intervals.

However, since the operation of assembling the overrunning clutch by sandwiching the roll + spring is performed entirely by hand, it is extremely inefficient, requires a long working time, and requires a laborious and laborious workforce. There was a problem.

In other words, manual operation of assembling the rollers and springs in the overrunning clutch requires that the rolls and springs, which are very small in size, be assembled one by one by hand, and of course, when pushing the spring, Because it is necessary to assemble in the compressed state, it is urgent to improve the efficiency and work speed very slowly and the productivity is greatly reduced even though it is hard work such as the finger hurts and sometimes the spring is sprung up in the process of pressing hard with the finger .

For reference, a conventional jig device which can mechanically and easily assemble a roll and a spring necessary for an overrunning clutch (also referred to as a "driver cell") installed in an automotive start motor has not existed to date.

Therefore, in the present invention, the work of assembling the roll and the spring to the overrunning clutch is made easier and quicker, and more particularly, the spring is compressed more easily through the mechanical device and inserted into the overrunning clutch The present invention provides a semi-automatic jig for a roll-spring assembly of a new automotive start motor overrunning clutch which can greatly contribute to the improvement of productivity as it is completed.

According to an aspect of the present invention, there is provided a unit inner wear fixing jig (100) having a roll seating groove (110), a spring seating groove (120), and a slide operation groove (130); (200) for compressing spring for compressing the spring unit (12) and returning to the original position when the spring unit (12) is released; A rotary flow type jig body (300) for pushing the five protrusions (210) protruding from the outer periphery of the rotary body at a predetermined angle; A top-and-bottom push-up coupling 400 for pushing up and down five upwardly and downwardly, A milifin pushing action cylinder device 500 for applying the touch and the power required to push up the up-down push-up combination 400 including the up-down push-down push-up pin 410; And a unit inner guide rod 600 for guiding the inside of the roll unit 11 and the spring unit 12 in the upward and downward directions to prevent the roll unit 11 and the spring unit 12 from being separated.

As described above, the jig device for the roll-spring assembling of the motor start overrunning clutch of the present invention is characterized in that the roll unit 11 and the spring unit 12, which are necessary for overrunning the motor start motor, As it is possible to assemble precisely by semiautomatic method, it can be very helpful to increase the productivity and quality of auto start motor overrunning products.

In addition, the upper and lower push-up joints 400 and the push-up push-

And a plurality of roll seating grooves 110 formed in the unit fixing jig body 100 and a bottom surface portion of the spring seating grooves 120. The roll seating grooves 110 are pushed upward by a predetermined distance, The unit 11 and the spring unit 12 can be assembled into the overrunning clutch 10. The upper and lower push pins 410 protruding at a constant height at each of the five equally- Respectively,

At this time, each of the upper and lower pushing pins 410 is positioned at a lower side (within a certain depth) inside the roll seating groove 110 and the spring seating groove 120 formed in the unit innerwear fixing jig 100, The roll unit 11 and the spring unit 12 to be assembled serve as a support so that the roll unit 11 and the spring unit 12 to be assembled can be seated thereon. When the compression of the spring unit 12 is completed in accordance with the driving of the post-spring compression slide operation member 200, the over-running clutch 10 is lifted up to the operation of the push- In which the roll unit 11 and the spring unit 12 are assembled.

On the other hand, in the case of the rotary flow type jig 300, as described above, five (5) rear portions of the spring action slide slide 200 protruding outwardly outward of the unit inner wear fixing jig 100 The protruding portion collectively driving pushing grooves 310 are drilled to be engaged with the protruding portions 210,

The projecting portion pushing operation push groove 310 is formed by five corner portions 311 and a pentagonal shape extending between the corner portions 311 and the corner portions 311 to form a total of five straight portions 312,

The protrusions 210 of the spring action slide carriage 200 inclined obliquely are disposed at the five corner portions 311 at all the five positions so that the rotation is permitted to one side but stopped (not rotatable) The engaging groove portion 313 is formed.

The projecting portion 210 located at the angular portion 311 which is relatively far from the center of the circle is rotated by the angular portion 311 so as to be rotated at a predetermined angle in one direction, The protruding portion 210 is pushed forward in the process of moving to the linear portion 312 whose distance from the center of the circle is gradually reduced as compared to the center of the circle, It is possible to return to the original position by turning it again by a certain angle or by turning it in the opposite direction.

The unit inner guide rods 600 are configured such that the roll unit 11 and the spring unit 12 are seated and positioned in five roll seating grooves 110 and spring seating grooves 120 formed around the edges, The spring units 12 and the spring units 12 are prevented from being separated from each other when the roll units 11 and the spring units 12 are seated and taken out of the space. It is also a very useful part, such as serving as an effective guide wall to do.

In the case of the milifin pushing motion cylinder apparatus 500 provided below the upper and lower pushing-type coupling unit 400, the five upper and lower pushing-down pins 410 are pushed up according to a user's operation, An air cylinder device which is commonly used is applied as an automatic pushing device for an automation push operation in which the roll unit and the spring unit are transferred and assembled into the inside of the overrunning clutch corresponding to the upper portion after being taken out, The piston member 510, the air supply line 520, and other components moving up and down by pressure can be constructed.
