The specific implementation process is as follows: the feeding conveyor belt 8 conveys the rocker arm chamber cover into the processing station 10, the rocker arm chamber cover slides a certain distance towards the processing station 10 under the action of inertia, and at the moment, the rocker arm chamber cover possibly does not completely enter the processing station 10, and due to the continuous movement of the feeding conveyor belt 8, the feeding bulge 9 on the feeding conveyor belt 8 abuts against the rocker arm chamber cover in the movement process and pushes the rocker arm chamber cover to completely enter the processing station 10;
start step motor, step motor drives first pivot 1 and rotates, because first sprocket 101 on the first pivot 1 passes through the chain to be connected in the second sprocket 302 on the third pivot 3, and the drive ratio is 1: 1, a first gear 301 on the third rotating shaft 3 is meshed with a second gear 202 on the second rotating shaft 2, and the transmission ratio is 1; 1, the second rotating shaft 2 is driven by the first rotating shaft 1 to rotate along with the first rotating shaft, the rotating angles are the same, and the second rotating shaft 2 and the first rotating shaft 1 are in opposite rotating directions due to the fact that the second rotating shaft 2 and the first rotating shaft 1 are in one-time gear transmission, namely the first rotating shaft 1 rotates anticlockwise, and the second rotating shaft 2 rotates clockwise; the first rotating shaft 1 and the second rotating shaft 2 respectively drive the movable positioning blocks 6 on the first rotating shaft to rotate 90 degrees from an initial state to a processing state, and at the moment, the two movable positioning blocks 6 and the two fixed positioning blocks 5 on the processing table clamp the rocker arm chamber cover on the processing station 10 together to realize positioning.
In the process of rotating the first rotating shaft 1 from the initial state to the positioning state, since the first chain wheel 101 on the first rotating shaft 1 is connected to the second chain wheel 302 on the third rotating shaft 3 through a chain, the transmission ratio is 1: 1, a first gear 301 on the third rotating shaft 3 is meshed with a third gear 403 on the fourth rotating shaft 4, and the transmission ratio is 1; 4, therefore, the first rotating shaft 1 rotates by 90 degrees, the fourth rotating shaft 4 rotates by 360 degrees, and because the fourth rotating shaft 4 and the first rotating shaft 1 only pass through one-time gear transmission, the rotating directions of the fourth rotating shaft 4 and the first rotating shaft 1 are opposite, namely, the first rotating shaft 1 rotates anticlockwise, the fourth rotating shaft 4 rotates clockwise, and because the one-way bearing is arranged between the pushing cam 401 and the fourth rotating shaft 4, when the fourth rotating shaft 4 rotates clockwise, the cam does not rotate under the action of the one-way bearing.
In the process that the first rotating shaft 1 rotates from the initial state to the positioning state, the first chain wheel 101 rotates along with the first rotating shaft 1, the connecting rod eccentrically hinged to the end face of the first chain wheel 101 pushes the piston rod of the cylinder 13 to move towards the rodless cavity, and because the check valve at the top of the rodless cavity only allows outside air to enter and the check valve at the bottom of the rodless cavity only allows air to be discharged, the air in the rodless cavity is discharged through the check valve at the bottom; the gas enters the chip collecting frame 14 through another hose and is exhausted from the chip collecting frame 14 through the gas blowing hole, and the gas exhausted by the gas blowing pipe blows off the chips on the surface of the cover of the rocker arm chamber as the gas blowing pipe is arranged on the processing table; the processing scraps of the upper rocker arm chamber cover in the rodless chamber enter the scrap collecting frame 14 along with the gas and are blocked by the scrap filter screen of the vent hole, so that the collection of the processing scraps is realized.
Use current chasing bar to carry out tapping processing to four through-holes of rocking arm chamber cap, after the processing is accomplished, step motor drives first pivot 1 antiport, under the drive of first pivot 1, is located the rotatory 90 degrees of the movable locating piece 6 on the first pivot 1 and resumes initial condition, and the movable locating piece 6 that is located on the second pivot 2 also rotates 90 degrees and resumes initial condition.
In the process of restoring the first rotating shaft 1 from the positioning state to the initial state, since the first chain wheel 101 on the first rotating shaft 1 is connected to the second chain wheel 302 on the third rotating shaft 3 through a chain, the transmission ratio is 1: 1, a first gear 301 on the third rotating shaft 3 is meshed with a third gear 403 on the fourth rotating shaft 4, and the transmission ratio is 1; 4, the first rotating shaft 1 rotates 90 degrees, the fourth rotating shaft 4 rotates 360 degrees, and as the first rotating shaft 1 rotates in the reverse direction and the fourth rotating shaft 4 rotates in the opposite direction to the first rotating shaft 1, namely the fourth rotating shaft 4 rotates counterclockwise at the moment, the pushing cam 401 rotates along with the fourth rotating shaft 4 under the action of the one-way bearing; when the first rotating shaft 1 rotates 45 degrees from a positioning state, the fourth rotating shaft 4 rotates 180 degrees, the pushing cam 401 pushes the rocker arm chamber cover out of the machining position 10 in the rotation process, the rocker arm chamber cover is pushed to the discharging conveyor belt 11, the discharging bulge 12 on the discharging conveyor belt 11 is embedded into the groove of the rocker arm chamber cover, and in the moving process of the discharging conveyor belt 11, the discharging bulge 12 drags the rocker arm chamber cover out of the machining position 10, so that automatic discharging is realized.
In the process that the first rotating shaft 1 rotates from the locating state to the initial state, the first chain wheel 101 rotates along with the first rotating shaft 1 in the reverse direction, and the connecting rod eccentrically hinged to the end face of the first chain wheel 101 pushes the piston rod of the air cylinder 13 to move towards the rod cavity; the check valve at the top of the rodless cavity only allows outside air to enter, and the check valve at the bottom of the rodless cavity only allows air to be discharged, so that the air in the rodless cavity is sucked in by the check valve at the top; due to the action of the cylinder 13, outside air enters from the top of the rodless cavity through the hose from the scrap collecting hole 7; in the tapping process, the machining chips fall into the four chip collecting holes 7 below the through hole, and the machining chips in the chip collecting holes 7 are brought into the rodless cavity along with the air flow.
The foregoing are merely exemplary embodiments of the present invention, and no attempt is made to show structural details of the invention in more detail than is necessary for the fundamental understanding of the art, the description taken with the drawings making apparent to those skilled in the art how the several forms of the invention may be embodied in practice with the teachings of the invention. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several changes and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
