The rear cover gripper 3 is composed of a clamping jaw air cylinder C73, a moving air cylinder 74 and an upward moving air cylinder 75 (see the description and the attached figure 6); an upward moving cylinder 75 is arranged on the frame 1 through a moving cylinder 74; a clamping jaw cylinder C73 is mounted on the piston rod of the upward moving cylinder 75.

When the feeding conveyor 2 works, the driving motor 66 can drive the transmission chain 67 and the rear cover positioning disc 19 to move step by step through the transmission shaft; in this process, the workpiece rear cover 78 to be assembled is continuously placed on the rear cover positioning plate 19 to avoid the problem of material leakage; when the rear cover positioning disc 19 drives the workpiece rear cover 78 to move to a position opposite to the wedge-shaped positioning block 68, the corresponding cylinder pushes the wedge-shaped positioning block 68 to move, so that the wedge-shaped positioning block is inserted into the limiting bayonets 70 on two sides of the limiting disc 69 to complete the positioning work of the rear cover positioning disc 19, and then the clamping jaw cylinder C73, the moving cylinder 74 and the upward moving cylinder 75 on the rear cover gripper 3 cooperate to grip the workpiece rear cover 78 on the rear cover positioning disc 19 which is positioned to the positioning seat 5 to complete the feeding work of the workpiece rear cover 78.

Subsequently, the wedge-shaped positioning block 68 and the rear cover gripper 3 are sequentially reset, and when the transmission chain 67 drives the next rear cover positioning disc 19 provided with the workpiece rear cover 78 to be in the opposite position to the wedge-shaped positioning block 68, the feeding conveyor 2 and the rear cover gripper 3 can enter the next working cycle.

When the press-fitting device for the automobile starter rear cover bearing works, the divider 14 can continuously and repeatedly drive the positioning turntable 4 to rotate for a certain angle and then stop; and then the operation is stopped after the rotation of a certain angle is driven.

When the positioning turntable 4 drives one group of positioning seats 5 to move to a position above the ejector rod 16, the positioning turntable 4 stops acting, and the ejector rod cylinder 15 drives the ejector rod 16 to move upwards; in the process of upward movement of the ejector rod 16, the positioning core rod 18 of the upper positioning seat 5 is pushed to move upward after overcoming the elasticity of the inner return spring 25; when the positioning flange 24 of the positioning core rod 18 is abutted against the inner sliding sleeve 21 and the upper end of the positioning core rod is positioned above the rear cover positioning plate 19, the action of the ejector rod 16 is stopped. At the moment, the bearing stocker 6 and the bearing grabber 7 cooperate to place the workpiece bearing 76 on the bearing position at the upper end of the ejector rod 16 and then reset.

Then the ejector rod cylinder 15 drives the ejector rod 16 to reset, in the process, under the action of the inner return spring 25, the ejector rod 16 drives the workpiece bearing 76 to move to the inside of the inner sliding sleeve 21 and restore to the initial position.

After the ejector rod 16 is reset, the positioning rotary table 4 stops acting after rotating for a certain angle, and the positioning seat 5 provided with the workpiece bearing 76 moves to a station close to the gasket suction device 9; then the gasket feeder 8 and the gasket suction device 9 cooperate to place the workpiece gasket 77 on the end of the carrier rod 16 and reset (see the attached figure 24).

After the workpiece pad 77 is placed, the positioning turntable 4 stops acting after rotating for a certain angle, and at the moment, the positioning seat 5 provided with the workpiece bearing 76 and the workpiece pad 77 moves to a station close to the rear cover grabber 3; at this time, the loading conveyor 2 and the rear cover grabber 3 cooperate to place the workpiece rear cover 78 on the rear cover positioning disc 19 of the positioning seat 5 and then reset (see the attached figure 25 in the specification).

And then, after the positioning rotary disc 4 rotates for a certain angle, the positioning seat 5 provided with the workpiece rear cover 78 is stopped, and at the moment, the positioning seat 5 is positioned inside the bearing press-fitting device 10, and a certain gap is reserved between the limiting sleeve 22 of the positioning seat 5 and the limiting plate 51 (see the attached figure 26 of the specification). Then the press-fitting cylinder 53 acts to press the workpiece rear cover 78 down by the fitting ram 55; the workpiece rear cover 78 presses the inner sliding sleeve 21 to move downwards against the elastic force of the inner return spring 25 after being pressed (see the description and the attached figure 26); in the downward moving process of the inner sliding sleeve 21, the outer sliding sleeve 20 and the limiting sleeve 22 are driven by the limiting pin A26 to continuously move downward after overcoming the elastic force of the outer return spring 23; when the limiting sleeve 22 is in interference connection with the limiting plate 51 (see the attached figure 27 in the specification), the outer sliding sleeve 20 and the limiting sleeve 22 stop moving downwards; at this time, the assembly ram 55 continues to press down the workpiece rear cover 78, and the workpiece rear cover 78 moves downward relative to the positioning core bar 18; when the workpiece back cover 78 is moved down to the inside of the workpiece back cover 78 where the workpiece bearing 76 and the workpiece pad 77 are inserted, the downward movement of the assembly ram 55 is stopped. So far the workpiece bearing 76 and the workpiece spacer 77 are fitted to the inside of the workpiece back cover 78; then the press-fitting air cylinder 53 drives the assembly pressure head 55 to reset, and the positioning seat 5 resets under the action of the outer return spring 23 and the inner return spring 25; the workpiece rear cover 78, which has completed the assembly of the workpiece bearing 76 and the workpiece shim 77, is now positioned on the rear cover positioning plate 19 of the positioning socket 5.

After the above processes are finished, the positioning rotary disc 4 stops acting after acting and rotating for a certain angle; the positioning socket 5, which has now completed the assembly of the workpiece bearing 76 and the workpiece washer 77, is moved to a station adjacent to the blanking grabber 11.

Then the rotating cylinder 56, the clamping jaw cylinder B57 and the lifting cylinder 58 of the blanking grabber 11 cooperate to place the workpiece rear cover 78, which is assembled by the workpiece bearing 76 and the workpiece pad 77, on the rear cover positioning disc 19 of the steel ball assembler 12, and at the moment, the positioning seat 5 is restored to the empty state.

When the workpiece rear cover 78 which is assembled by the workpiece bearing 76 and the workpiece gasket 77 is placed on the rear cover positioning disc 19 of the steel ball assembler 12 by the blanking grabber 11, the blanking grabber 11 is reset; the corresponding air cylinder pushes the extrusion fixing block 59 to act, so that the workpiece back cover 78 is fixed on the back cover positioning plate 19 (see the description and the attached figure 17).

Then, the corresponding cylinder in the steel ball stocker 13 drives the sliding insertion tube 64 to move up and down once (see the attached figures 21 and 22 in the specification), the steel balls in the storage hopper 63 fall into the guide tube 65 through the sliding insertion tube 64, and then the steel balls fall into the Y-shaped receiving tube 61 of the steel ball assembler 12 along the guide tube 65 under the action of self gravity (see the attached figures 18 and 19 in the specification); then the corresponding air cylinder pushes the extrusion mandril 62 to move upwards; during the upward movement of the extrusion ejector rod 62, the steel ball in the Y-shaped bearing tube 61 is pushed into the workpiece rear cover 78, and the posture is kept unchanged. Then, other external equipment adsorbs and fixes the workpiece rear cover 78 and the steel ball through magnetic force, and the extrusion fixing block 59 and the extrusion ejector rod 62 reset; then other external equipment can transfer the fixed workpiece rear cover 78 and the steel ball to the lower process for processing through magnetic force. The steel ball assembler 12 completes the assembly of the steel balls.

In the working process of the ball distributor 12, the positioning turntable 4 acts to drive the vacant positioning seat 5 to move to the upper part of the ejector rod 16; the press mounting device of the automobile starter rear cover bearing completely finishes the assembly work of the workpiece bearing 76, the workpiece gasket 77 and the steel ball of the workpiece rear cover 78; the press-fitting device of the rear cover bearing can enter the next working cycle.
