Detailed Description

The principles and features of this invention are described below in conjunction with examples which are set forth to illustrate, but are not to be construed to limit the scope of the invention.

As shown in fig. 1 to 6, an isolator assembly assembling process is characterized in that: the method comprises the following steps:

s1, blanking the star wheel 5;

s2, arranging a roller 6 and a flat spring 7 in the star wheel 5;

s3, injecting grease into the star wheel 5;

s4, mounting the round gasket 3 on the star wheel 5;

s5, pressing the gear head, namely pressing the gear head 1 into the star wheel 5;

s6, installing the semicircular sheet 3 on the star wheel 5;

s7, sleeving the outer cover, namely sleeving the outer cover 4 on the star wheel 5;

and S8, edge grinding and edge rolling of the outer cover.

And S3, injecting grease into the inner cavity of each roller flat spring of the star wheel, weighing the product twice through a weighing sensor, wherein the weighing twice comprises weighing of empty products and weighing again after grease injection, so that at least 0.35g of grease is injected into the inner cavity of each roller flat spring of the star wheel, and the grease injection amount is controlled to be 2.3-2.4 g.

In the step S5, the tooth head 1 is pressed into the star wheel 5 by the rotary cylinder, and the rotary cylinder presses down while rotating, thereby controlling the tooth head pressing amount and preventing the tooth head from not pressing in place.

And S6, detecting the semicircular sheet on the feeding belt through the optical fiber sensor, and giving an alarm if the optical fiber sensor does not detect the semicircular sheet.

The circular gasket 3 and the semicircular sheet 2 are positioned between the outer cover and the star wheel to prevent the grease in the star wheel 5 from leaking and ensure the smooth rotation of the star wheel, thereby achieving the sealing effect.

In this embodiment, the number of the semicircular pieces is two.

And in the step S7, the outer cover on the feeding belt is sucked through the sucking disc, the sucking disc is provided with a sensor, when the sensor detects that the outer cover is arranged below the sucking disc, the sensor is bright, otherwise, the sensor is not bright.

When the outer cover is sleeved, the outer cover is pushed through the air cylinder and is pressed downwards, the outer cover is prevented from not being pressed in place, the outer cover is sleeved on the star wheel, and the semicircular sheet and the circular gasket which have a sealing effect are arranged between the outer cover and the star wheel.

In the step S8, the outer cover is firstly rolled and then curled, the pressing force is controlled through the pressure sensor, and the pressure sensor can give an alarm when the pressing force is too large or too small.

The step A1 of first visual detection is included between the steps S2 and S3, and the first visual detection A1 is used for detecting whether the roller and the flat spring are neglected to be installed or not and whether the flat spring is installed more or reversely.

As shown in fig. 7, a second visual inspection step a2 is included between steps S7 and S8, and the second visual inspection step a2 detects the size of the addendum circle in order to detect whether the tooth heads are inverted and fall-over, and if the product is acceptable, the product is continuously conveyed by the conveyor belt 9, and the next assembly operation is performed, and if the product is not acceptable, the product is pushed into the waste tray 11 by the pushing cylinder 10.

A step B1 of detecting the total length of the isolator is included between the steps A2 and S8. The total length of the isolator is detected through the grating ruler, the tolerance range of 0.05mm is guaranteed, the green light of the grating ruler is lightened if the product is qualified, and the red light of the grating ruler is lightened if the product is unqualified.

And (C1) after the step S8, installing a check ring 8 at one end of the star wheel 5 far away from the gear head 1, and detecting the distance of the check ring, wherein the distance of the check ring is the distance between the check ring 8 and the star wheel 5, and the step C is qualified when the distance is more than 8.6 mm.

And the step D1 of detecting the slip torque is included after the step C1, and the product is qualified if the measured slip torque is not more than 0.25 N.m.
