Description

Technical Field

[0001] The utility model relates to the technical field of bushing press-fitting equipment, in particular to an automatic press-fitting machine for bushings. Background Art

[0002] Bushings are used outside mechanical parts to achieve sealing, wear protection and other functions. Their function is to withstand vibration, friction and corrosion in various harsh working environments to protect the wrapped parts. After damage, they are easy to replace, with low cost and good economy.

[0003] However, when the existing small bushing press is used to press the bushing, the operator is required to place the workpiece under the press and then place the bushing on the workpiece. The workpiece needs to be fixed with a clamp, and the clamp can only fix workpieces of the same specification to ensure that the punching holes on the upper surface of the workpiece are vertically corresponding to the press. If the specifications of the workpieces fixed by the clamp are different, the punching holes on the upper surface of the workpiece cannot be vertically corresponding to the press, resulting in the bushing being unable to be pressed into the punching holes on the upper surface of the workpiece, making the versatility of the automatic bushing press poor. At the same time, when the operator places the bushing on the workpiece, once an error operation occurs, the operator's hand will be crushed by the press, which poses a certain safety risk.

When the rotating ring rotates, it drives the carrying plate to rotate. When the carrying plate rotates, the bushing sleeve body inside the placement hole on the upper surface of the carrying plate is rotated to the pressing machine body Below the ejection end, turn off the second servo motor, the operator starts the press machine body, the ejection end of the press machine body is ejected, and the bushing sleeve body is pressed down, so that the bushing sleeve body passes through the placement hole on the upper surface of the carrier plate and enters the inside of the punching hole on the upper surface of the workpiece, completing the press-fitting of the bushing sleeve body, and starting the second servo motor again, the placement hole on the upper surface of the carrier plate without the bushing sleeve body leaves the ejection end of the press machine body, making it convenient for the operator to place the bushing sleeve body inside the placement hole on the upper surface of the carrier plate again, avoiding the operator from placing the bushing directly under the press machine body, effectively preventing the operator's hands from being crushed by the press machine, and reducing safety risks.

The screw rod 22 rotates inside the through hole on the side surface of the partition 19. When the screw rod 22 rotates, it is threadedly connected to the threaded hole at one end of the adjustment block 21, so that the adjustment block 21 slides along the slide rail 4. When the adjustment block 21 slides, it drives the supporting plate 5 to change its position, thereby adjusting the position of the workpiece 2.

[0024] Among them, a rotating rod 23 is fixedly connected to the middle part of the gear 6, and the lower end of the rotating rod 23 is rotatably connected to the bottom of the slide groove on the upper surface of the supporting plate 5.

[0026] Among them, a plurality of groups of placement holes are opened on the upper surface of the carrier plate 14, one group of placement holes on the upper surface of the carrier plate 5 corresponds to the ejection end of the press body 16 and the punching holes on the upper surface of the workpiece 2, and a bushing sleeve 26 is placed inside the placement hole on the upper surface of the carrier plate 14. The diameter of the bushing sleeve 26 is the same as the diameter of the placement hole on the upper surface of the carrier plate 5.

When the driven umbrella wheel 27 rotates, it drives the worm 13 to rotate inside the through holes on the upper side surfaces of the two groups of mounting ear plates 17.

[0028] The working principle provided by the utility model is as follows: the operator first places the workpiece 2 between the two groups of clamping plates 8, the operator makes the punching holes on the upper surface of the workpiece 2 correspond to one group of placement holes on the upper surface of the carrier plate 14 and the ejection end of the press body 16, the operator starts the electric cylinder 25, the ejection end of the electric cylinder 25 is ejected, and the push plate 24 is pushed along the inner wall groove of the slide groove on the upper surface of the carrier plate 5, pushing one of the racks 7 to slide, and the rack 7 engages the gear 6 while sliding and drives the gear 6 to rotate, and when the gear 6 rotates, it engages another group of racks 7 to move, so that the two groups of clamping plates 8 are close to each other, the workpiece 2 is clamped and fixed, and the workpiece 2 is prevented from being deviated. When the workpiece 2 is moved, and different workpieces 2 have different widths, and the punching holes on the upper surface of the workpiece 2 do not correspond to the positions of the holes placed on the upper surface of the carrier plate 14, the operator starts the first servo motor 20, and the rotation of the power output end of the first servo motor 20 drives the screw rod 22 to rotate. The screw rod 22 rotates inside the through hole on the side surface of the partition 19. When the screw rod 22 rotates, it is threadedly connected with the threaded hole at one end of the adjustment block 21, so that the adjustment block 21 slides along the slide rail 4. When the adjustment block 21 slides, it drives the carrier plate 5 to change its position, thereby adjusting the position of the workpiece 2, so that the punching holes on the upper surface of the workpiece 2 correspond to the holes placed on the upper surface of the carrier plate 14. When the workpiece 2 is fixed, the operator moves the upper and lower surfaces of the carrier plate 14 in turn. A bushing sleeve 26 is placed inside the surface placement hole, and the operator starts the second servo motor 29. The power output end of the second servo motor 29 rotates to drive the active umbrella wheel 28 to rotate. When the active umbrella wheel 28 rotates, it engages with the driven umbrella wheel 27. When the driven umbrella wheel 27 rotates, it drives the worm 13 to rotate inside the through hole on the upper side surface of the two sets of mounting ear plates 17. When the worm 13 rotates, it engages with the worm wheel 12 to rotate. When the worm wheel 12 rotates, it drives the rotating ring 11 to rotate on the outer surface of the fixed column 10. When the rotating ring 11 rotates, it drives the bearing plate 14 to rotate. When the bearing plate 14 rotates, the bushing sleeve 26 inside the hole on the upper surface of the bearing plate 14 is rotated to the lower side of the ejection end of the press body 16 The second servo motor 29 is turned off, and the operator starts the press machine body 16. The ejection end of the press machine body 16 is ejected, and the bushing sleeve 26 is pressed down, so that the bushing sleeve 26 passes through the placement hole on the upper surface of the carrier plate 14 and enters the inside of the punching hole on the upper surface of the workpiece 2, completing the press-fitting of the bushing sleeve 26. The second servo motor 29 is started again, and the placement hole on the upper surface of the carrier plate 14 without the bushing sleeve 26 leaves the ejection end of the press machine body 16, so that the operator can place the bushing sleeve 26 inside the placement hole on the upper surface of the carrier plate 14 again. After the press-fitting of the bushing sleeve 26 is completed, the operator controls the electric cylinder 25 to retract, and the two sets of clamping plates 8 move away from each other, and the workpiece 2 can be removed.
