Description

Technical Field

[0001] The present invention relates to the field of automatic assembly of ball bearings, and particularly to a sleeve combining device for an automatic ball bearing assembly machine. Background Art

[0002] A ball bearing is a type of rolling bearing. The ball is installed between the inner steel ring and the outer steel ring, and can withstand a large load. It is also called a ball bearing. At present, the assembly of ball bearings has been automated. During assembly, the inner sleeve needs to be placed inside the outer sleeve first, then the outer sleeve is pushed to the bottom of the robotic arm by a machine to inject steel balls, and finally the steel balls are separated by a ball separator, and then the cage is installed.

[0003] However, after the inner sleeve is placed inside the outer sleeve in the prior art, the outer sleeve can be moved by a mechanical device. During this process, the inner sleeve inside the outer sleeve moves randomly under the action of inertia and friction, and the final positions of different inner sleeves are not unified, which affects the bead injection efficiency and causes irregular wear of the bead injection head, accelerating aging.

[0004] Therefore, based on the above technical problems, it is necessary for those skilled in the art to develop a sleeve combining device for an automatic ball bearing assembly machine. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a sleeve combining device for an automatic ball bearing assembly machine.

[0006] To solve the above technical problem, the technical solution of the present invention is as follows:

[0007] A sleeve combining device for an automatic ball bearing assembly machine includes a tabletop. A baffle is fixedly connected to the top edge of the tabletop, and a support base is fixedly connected to the bottom of the tabletop. Two base blocks are symmetrically distributed front and back on one side of the support base. A motor is fixedly connected to the surface of the front base block. A threaded rod is fixedly connected to the output shaft of the motor. One end of the threaded rod penetrates through the front base block and extends between the two base blocks. Both ends of the threaded rod are movably connected to the two base blocks through bearings. A guide rod is arranged at the bottom of the threaded rod. Both ends of the guide rod are fixedly connected to the two base blocks. A movable seat is arranged on the threaded rod. A vertical plate is fixedly connected to one side of the movable seat. A first electric push rod is fixedly connected to one side of the vertical plate. A U-shaped block is fixedly connected to one end of the first electric push rod. Two limit rods are symmetrically distributed front and back inside the U-shaped block. A short plate and a second electric push rod are arranged at the top of the rear limit rod. The bottom of the short plate is fixedly connected to the limit rod. A movable clamping plate is hinged to the top of the short plate. The bottom end of the second electric push rod is hinged to the limit rod, and the top end of the second electric push rod is hinged to the movable clamping plate.

[0008] Preferably, a bidirectional threaded rod is provided inside the U-shaped block. The bidirectional threaded rod is threadedly connected to both limiting rods, and both ends of the bidirectional threaded rod are movably connected to the front and rear side walls of the U-shaped block respectively.

[0009] Preferably, one end of the bidirectional threaded rod penetrates through the side wall of the U-shaped block and extends to the front side of the U-shaped block. A knob is fixedly connected to the end of the bidirectional threaded rod located on the front side of the U-shaped block.

[0010] Preferably, a chute is provided on the inner wall of the U-shaped block. One end of each of the two limiting rods is fixedly provided with a slider, and the slider is located inside the chute and matches the chute.

[0011] Preferably, the movable seat is threadedly connected to the threaded rod, and the movable seat is movably sleeved on the guide rod.

[0012] Preferably, the movable clamping plate is arranged as an arc-shaped plate, and a rubber pad is fixedly connected to one side of the movable clamping plate.

[0013] Adopting the above technical solution, the following beneficial effects are achieved:

[0014] By starting the motor and the first electric push rod, the U-shaped block and the limiting rods can be driven to move forward and backward as well as left and right, which is beneficial to driving the outer sleeve and the inner sleeve to move to the specified position on the table for subsequent bead injection work. By controlling the second electric push rod on the rear limiting rod, the movable clamping plate can be rotated to fix the inner sleeve, avoiding the random movement of the inner sleeve under the action of friction or inertia, thereby reducing the impact on the bead injection work and reducing the wear of the bead injection head. By turning the knob, the bidirectional threaded rod can be driven to rotate, and then the two limiting rods can be driven to move inward or outward simultaneously, which is beneficial to adapting to outer sleeves of different specifications and improving the applicability.

In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0023] See Figures 1-4As shown in the figure, a sleeve assembling device for a ball bearing automatic assembling machine according to the present invention includes a table 1. A baffle 2 is fixedly connected to the top edge of the table 1. A support base 3 is fixedly connected to the bottom of the table 1. Two base blocks 4 symmetrically distributed front and back are fixedly connected to one side of the support base 3. A motor 5 is fixedly connected to the surface of the front base block 4. A threaded rod 6 is fixedly connected to the output shaft of the motor 5. One end of the threaded rod 6 penetrates through the front base block 4 and extends between the two base blocks 4. Both ends of the threaded rod 6 are movably connected to the two base blocks 4 through bearings. A guide rod 7 is provided at the bottom of the threaded rod 6. The guide rod 7 is parallel to the threaded rod 6. Both ends of the guide rod 7 are fixedly connected to the two base blocks 4. A movable seat 8 is arranged on the threaded rod 6. A vertical plate 9 is fixedly connected to one side of the movable seat 8. A first electric push rod 10 is fixedly connected to one side of the vertical plate 9. In actual application, the first electric push rod 10 is fixedly connected to the vertical plate 9 through bolts, which is convenient for disassembly and maintenance. One end of the first electric push rod 10 is fixedly connected to a U-shaped block 11. The U-shaped block 11 includes two base rods symmetrically distributed front and back and a connecting rod in the middle. The connecting rod is integrally formed with the base rods, and the connecting rod is vertically distributed with the base rods. Two limit rods 12 symmetrically distributed front and back are arranged inside the U-shaped block 11. A short plate 13 and a second electric push rod 14 are arranged at the top of the rear limit rod 12. The bottom of the short plate 13 is fixedly connected to the limit rod 12. The top of the short plate 13 is hinged with a movable clamping plate 19. The bottom end of the second electric push rod 14 is hinged to the limit rod 12, and the top end of the second electric push rod 14 is hinged to the movable clamping plate 19. By controlling the elongation of the second electric push rod 14, the movable clamping plate 19 can be driven to rotate around the hinge point, so as to fix the inner sleeve and prevent the inner sleeve from moving irregularly due to friction or inertia.

[0024] Preferably, a bidirectional threaded rod 15 is arranged inside the U-shaped block 11. The bidirectional threaded rod 15 is threadedly connected to both limit rods 12. Both ends of the bidirectional threaded rod 15 are movably connected to the front and rear side walls of the U-shaped block 11. In actual application, two threads in different directions are arranged on the bidirectional threaded rod 15 and are respectively matched with the two limit rods 12.

[0025] Preferably, one end of the bidirectional threaded rod 15 penetrates through the side wall of the U-shaped block 11 and extends to the front side of the U-shaped block 11. A knob 16 is fixedly connected to the end of the bidirectional threaded rod 15 located on the front side of the U-shaped block 11. By turning the knob 16, it is convenient to drive the bidirectional threaded rod 15 to rotate.

[0026] Preferably, a chute 17 is opened on the inner wall of the U-shaped block 11. One end of each of the two limit rods 12 is fixedly provided with a slider 18. The slider 18 is located inside the chute 17 and is matched with the chute 17, so that the limit rod 12 can be slidably connected to the inner wall of the U-shaped block 11. The limit rod 12 can be slidably connected to the U-shaped block 11 through the slider 18 and the chute 17. Since the limit rod 12 is threadedly connected to the bidirectional threaded rod 15, by rotating the threaded rod 6, the two limit rods 12 can be driven to move inward or outward simultaneously, which is convenient for adjusting the distance between the two limit rods 12 to adapt to outer sleeves of different specifications.

[0027] Preferably, the movable seat 8 is threadedly connected to the threaded rod 6, and the movable seat 8 is movably sleeved on the guide rod 7, which is beneficial to realize the forward and backward movement of the movable seat 8 by the rotation of the threaded rod 6, and further realize the pushing of the outer sleeve.

[0028] Preferably, the movable clamping plate 19 is arranged as an arc-shaped plate, and a rubber pad is fixedly connected to one side of the movable clamping plate 19, which is beneficial to avoid the rigid contact between the movable clamping plate 19 and the inner sleeve, improve the buffering performance, and at the same time has a large friction force and is not easy to fall off during the movement.

[0029] Working principle:

[0030] First, start the first electric push rod 10. The first electric push rod 10 extends to move the U-shaped block 11 and the limiting rod 12 left and right, so that the outer sleeve is located between the two limiting rods 12. Then control the second electric push rod 14 to extend to push one end of the movable clamping plate 19 to rotate upward, and make the other end of the movable clamping plate 19 rotate into the inner sleeve. Continue to rotate to clamp the inner sleeve. After that, operate the motor 5. The operation of the motor 5 drives the threaded rod 6 to rotate, and then drives the movable seat 8, the vertical plate 9, the first electric push rod 10, the U-shaped block 11 and the limiting rod 12 to move back and forth, which can drive the outer sleeve to move back and forth. The inner sleeve will not move randomly due to friction or inertia during the movement of the outer sleeve. When the specification of the outer sleeve to be processed changes, rotate the knob 16 to drive the bidirectional threaded rod 15 to rotate, and then drive the two limiting rods 12 to move inward or outward at the same time, so as to adjust the distance to adapt to outer sleeves of different specifications.

[0031] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present invention, various changes, modifications, substitutions and variations of these embodiments still fall within the protection scope of the present invention.
