Description

Technical Field

[0001] The present invention relates to the technical field of bearing assembly, in particular to an assembly device for producing rocker arm connecting rod bearings. Background Art

[0002] Bearings are components that stabilize and reduce the load friction coefficient during mechanical transmission. Alternatively, they are components that reduce the friction coefficient during power transmission and maintain the center position of the shaft when other parts move relative to each other on the shaft.

[0004] After the balls are placed in the inner and outer rings, the device completes the assembly by pushing the outer ring and the balls. Although this solves the problem of low manual assembly efficiency, after the balls are placed in the inner and outer rings, the device squeezes the outer ring and the balls. During the squeezing, the balls are easily stuck to each other and become stuck. As the squeezing force increases, wear will occur between the balls, thereby affecting the overall assembly quality.

At the same time, the third round rod drives the inner ring to vibrate, so that the position between the balls is automatically adjusted to prevent extrusion damage. In addition, by using the second electromagnet to attract the iron block, the third round rod can be prevented from squeezing the inner ring with excessive force to cause damage, thereby improving the assembly quality.

[0022] 2. The present invention is provided with a push plate and a pressure sensor. When the push plate pushes the outer ring and the outer ring squeezes the balls, the pressure sensor monitors the push plate pressure. When the pressure sensor detects that the pressure is too high, it will feedback to the control panel to stop the servo motor from rotating for a certain period of time. The second electromagnet continues to drive the inner ring to vibrate left and right, and adjust the position between the balls again. After the servo motor stops for a certain period of time, it restarts until the pressure is less than the preset value, thereby improving the bearing assembly quality.

DETAILED DESCRIPTION

[0032] See also Figures 1 to 8 The present invention provides a technical solution: an assembly device for producing rocker arm connecting rod bearings, comprising a housing 1, a servo motor 2 located above the housing 1, an output shaft of the servo motor 2 passing through the housing 1 and mounted with a first round rod 6, an outer wall of the first round rod 6 being mounted with a cam 10 and a first support plate 7, and further comprising:

[0033] The first unloading mechanism 100 includes a second conveying pipe 101 for conveying the outer ring 102 to the first support plate 7;

[0034] The second unloading mechanism 200 includes a third conveying pipe 201 for conveying the inner ring 202 to the outer ring 102 on the first support plate 7;

[0035] The first conveying pipe 3 is used to convey the balls 301 into between the outer ring 102 and the inner ring 202;

[0036] The extrusion mechanism 300 includes several first cylinders 303 and a vibration assembly. A first piston rod 302 is slidably mounted inside the first cylinder 303. A push plate 305 is mounted on one side of the first piston rod 302. A pressure sensor is installed inside the push plate 305. When the air pressure inside the first cylinder 303 increases, the first piston rod 302 drives the push plate 305 to squeeze the outer ring 102 and the ball 301. At the same time, the vibration assembly drives the inner ring 202 to vibrate back and forth, adjusting the position of the ball 301.

[0037] The vibration assembly includes a third retaining ring 304 installed on the outer wall of the first piston rod 302. The lower end surface of the third retaining ring 304 passes through the first support plate 7 and is installed with a second support plate 307. The upper end surface of the second support plate 307 is symmetrically installed with a third support plate 312. The outer wall of the third support plate 312 is installed with a second electromagnet 310. The upper end surface of the third support plate 312 abuts against a fourth round rod 309. The outer wall of the fourth round rod 309 is installed with a third round rod 308. The lower end surface of the third round rod 308 is installed with an iron block 311. The side of the third round rod 308 away from the iron block 311 passes through the first support plate 7.

[0038] Further, such as Figure 2 and Figure 3 As shown, the second delivery pipe 101 is installed on the housing 1, and a first support frame 103 is installed on the outer wall of the second delivery pipe 101. A first extrusion rod 104 is slidably installed on the inner wall of the first support frame 103. One side of the first extrusion rod 104 abuts against the cam 10, and the side of the first extrusion rod 104 away from the cam 10 passes through the second delivery pipe 101. A first retaining ring 105 is installed on the outer wall of the first extrusion rod 104, and a first tension spring 106 is sleeved on the outer wall of the first extrusion rod 104. The two ends of the first tension spring 106 are respectively installed on the first retaining ring 105 and the first support frame 103;

[0039] The cam 10 squeezes the first squeezing rod 104, and the first squeezing rod 104 squeezes the outer ring 102 in the second delivery tube 101 to prevent it from falling;

[0040] When the cam 10 does not squeeze the first squeezing rod 104, the first tension spring 106 contracts, driving the first squeezing rod 104 to move away from the outer ring 102 in the second conveying tube 101 through the first retaining ring 105. At this time, the outer ring 102 falls onto the first support plate 7.

[0041] Further, such as Figure 2 and Figure 4 As shown, the third delivery tube 201 is installed on the housing 1, and a second support frame 203 is installed on the outer wall of the third delivery tube 201. A second extrusion rod 204 is slidably installed on the inner wall of the second support frame 203. One side of the second extrusion rod 204 abuts against the cam 10, and the side of the second extrusion rod 204 away from the cam 10 passes through the third delivery tube 201. A second retaining ring 205 is installed on the outer wall of the second extrusion rod 204, and a second tension spring 206 is sleeved on the outer wall of the second extrusion rod 204. The two ends of the second tension spring 206 are respectively installed on the second retaining ring 205 and the second support frame 203;

[0042] The cam 10 squeezes the second squeezing rod 204, and the second squeezing rod 204 squeezes the inner ring 202 in the third delivery tube 201 to prevent it from falling;

[0043] When the cam 10 does not squeeze the second squeezing rod 204, the second tension spring 206 contracts, driving the second squeezing rod 204 to move away from the inner ring 202 in the third conveying tube 201 through the second retaining ring 205. At this time, the inner ring 202 falls into the outer ring 102 on the first support plate 7.

[0044] Further, such as Figure 1 As shown, the first delivery pipe 3 is fixedly connected to the housing 1;

[0045] Further, such as Figure 5 and Figure 8 As shown, the first cylinder 303 is installed on the first support plate 7, the lower end surface of the first cylinder 303 passes through the first support plate 7 and is connected to the second cylinder 314, the second piston rod 313 is slidably installed on the inner wall of the second cylinder 314, and the first support plate 7 is a rubber plate;

[0046] When the second piston rod 313 moves in the second cylinder 314 , the gas in the second cylinder 314 enters the first cylinder 303 ;

[0047] Further, such as Figures 5 to 7 As shown, the first piston rod 302 is provided with a third tension spring 306 on its outer sleeve, and both ends of the third tension spring 306 are respectively mounted on the third retaining ring 304 and the first cylinder 303;

[0048] When the air pressure in the first cylinder 303 increases, the third tension spring 306 extends, driving the third retaining ring 304 and the first piston rod 302 to move;

[0049] When the air pressure in the first cylinder 303 decreases, the third tension spring 306 contracts, driving the third retaining ring 304 and the first piston rod 302 to move in opposite directions;

[0050] Further, such as Figure 2 As shown, the inner wall of the housing 1 is mounted with a second round rod 8, the lower end surface of the second round rod 8 is mounted with a first electromagnet 9, and the third round rod 308 is magnetic;

[0051] The first electromagnet 9 is used to attract the third round rod 308;

[0052] Further, such as Figure 8 As shown, a ring 317 is installed on the inner wall of the housing 1, and a first inclined surface 315 and a second inclined surface 316 are installed on the inner wall of the ring 317;

[0053] Further, such as Figure 1 As shown, a control panel 4 is installed on the outer wall of the housing 1, and an outlet 5 is opened on the outer wall of the housing 1;

[0054] The control panel 4 is used to set relevant parameters, and the outlet 5 is used to discharge the assembled bearings.

[0055] Furthermore, a sliding groove is provided on the outer wall of the first support plate 7 , the sliding groove is slidably connected to the third round rod 308 , and the direction of the sliding groove is consistent with the axis of the fourth round rod 309 .

[0056] Working principle: Step 1: After connecting to the external power supply, the first conveying tube 3 is connected to the ball assembly machine, and then the outer ring 102 and the inner ring 202 are placed in the second conveying tube 101 and the third conveying tube 201 respectively. The servo motor 2 is controlled by the control panel 4 to rotate intermittently 90 degrees. The servo motor 2 drives the first round rod 6 to rotate, and the first round rod 6 drives the cam 10 and the first support plate 7 to rotate. When the cam 10 does not squeeze the first squeezing rod 104, the first tension spring 106 contracts and drives the first squeezing rod 104 to move away from the outer ring 102 in the second conveying tube 101 through the first retaining ring 105. At this time, the outer ring 102 falls onto the first support plate 7 and is located on the side of the push plate 305;

[0057] Step 2: When the servo motor 2 rotates 90 degrees for the first time, the cam 10 will first squeeze the first squeezing rod 104, and the first squeezing rod 104 squeezes the outer ring 102 in the second conveying tube 101 to prevent it from falling. When the servo motor 2 completes the 90-degree rotation, the cam 10 no longer squeezes the first squeezing rod 104 and the second squeezing rod 204. At this time, the outer ring 102 falls on the first support plate 7 again. At the same time, the second tension spring 206 contracts and drives the second squeezing rod 204 to move away from the inner ring 202 in the third conveying tube 201 through the second retaining ring 205. The inner ring 202 falls into the inside of the outer ring 102, and the third round rod 308 is located inside the inner ring 202. At this time, the outer wall of the inner ring 202 away from the servo motor 2 abuts against the outer ring 102, and the gap between the outer wall of the inner ring 202 close to the servo motor 2 and the outer ring 102 is larger.

[0058] Step 3: When the servo motor 2 rotates 90 degrees for the second time, the cam 10 will first squeeze the first squeezing rod 104 and the second squeezing rod 204. The first squeezing rod 104 squeezes the outer ring 102 in the second conveying tube 101 to prevent it from falling, and the second squeezing rod 204 squeezes the inner ring 202 in the third conveying tube 201 to prevent it from falling. When the servo motor 2 completes the 90-degree rotation, the first conveying tube 3 conveys a certain number of balls 301 into the gap between the outer ring 102 and the inner ring 202.

[0059] Step 4: When the servo motor 2 rotates 90 degrees for the third time, the first inclined surface 315 squeezes the second piston rod 313, and the second piston rod 313 slides into the second cylinder 314. The gas in the second cylinder 314 enters the first cylinder 303. The air pressure in the first cylinder 303 increases, squeezing the first piston rod 302 to extend. The first piston rod 302 drives the push plate 305 and the third retaining ring 304 to move. The push plate 305 pushes the outer ring 102 to move, and the outer ring 102 squeezes the ball 301. Since the fourth round rod 309 will slide on the third support plate 312 at this time, the third round rod 308 will limit the inner ring 202, and the pressure sensor in the push plate 305 will monitor the pressure.

[0060] At the same time, the third retaining ring 304 drives the second support plate 307 to move, and the second support plate 307 drives the third support plate 312 to move. At the same time, the second electromagnet 310 is energized intermittently at a rapid speed. The second electromagnet 310 attracts the iron block 311, and the iron block 311 drives the third round rod 308 to move back and forth. The third round rod 308 drives the fourth round rod 309 to slide on the third support plate 312. At the same time, the third round rod 308 drives the inner ring 202 to vibrate, so that the position between the balls 301 is automatically adjusted to prevent extrusion damage.

[0061] If the balls 301 are not adjusted to the optimal position, when the pressure sensor detects that the pressure is too high, it will feedback to the control panel 4 to stop the servo motor 2 for a certain period of time, and the second electromagnet 310 will continue to drive the inner ring 202 to vibrate left and right. After the servo motor 2 stops for a certain period of time, the servo motor 2 will restart until the pressure is less than a predetermined value. When the servo motor 2 completes a 90-degree rotation, the bearing is assembled under the pressure of the outer ring 102. At this time, the second electromagnet 310 stops working, and the third support plate 312 no longer supports the fourth rod 309. The fourth rod 309 drops above the second support plate 307. At this time, the third rod 308 no longer blocks the inner ring 202.

[0062] Step 5: When the servo motor 2 rotates 90 degrees for the fourth time, as the second inclined surface 316 continues to squeeze the second piston rod 313, the second piston rod 313 slides into the second cylinder 314, and the gas in the second cylinder 314 enters the first cylinder 303. The air pressure in the first cylinder 303 increases, squeezing the first piston rod 302 to extend. The first piston rod 302 drives the push plate 305 to push the bearing out of the outlet 5 first. The pressure sensor detects that the pressure is decreasing, controls the first electromagnet 9 to be energized, and the first electromagnet 9 attracts the third round rod 308, and the third round rod 308 drives the fourth round rod 308 to move. The rod 309 and the iron block 311 rise. At the same time, the second piston rod 313 moves away from the second inclined surface 316, and the third tension spring 306 contracts, driving the first piston rod 302 to move. The first piston rod 302 drives the push plate 305 to return to the initial position. At the same time, the first piston rod 302 drives the third baffle ring 304 to move. The third baffle ring 304 drives the third support plate 312 to move to the bottom of the fourth round rod 309 through the second support plate 307 and supports it. When the servo motor 2 completes a 90-degree rotation, the first electromagnet 9 stops working and the third round rod 308 returns to its initial position.
