Description

Technical Field

[0001] The utility model relates to the technical field of bearing assembly equipment, in particular to a turning and sleeve-fitting mechanism for bearing assembly. Background Art

[0002] Bearings usually include an outer ring, an inner ring, steel balls, a cage assembly, and a sealing ring. The center-to-center distance of the bearing groove determines the size of the gap between the outer ring and the inner ring after installation. In terms of bearing precision, the smaller the gap, the higher the qualification of the bearing. When the gap is too large, it will cause abnormal noise during use of the bearing and uneven pressure on each surface of the bearing. Therefore, the center-to-center distance is crucial for the assembly of the bearing.

[0003] During the bearing assembly process, it is common for one assembly component to correspond to one corresponding device, which results in waste of space utilization and power consumption, and increases the purchase cost of the equipment accordingly.

[0004] The fully automatic assembly equipment of bearings in the prior art is usually only able to assemble bearings with a single layer of steel balls. For bearings with double layers of steel balls, the steel balls need to be installed twice, which is a complicated process. The positioning of the steel balls is difficult and the assembly efficiency is low. Utility Model Content

[0042] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0043] like Figure 1-5 As shown, this embodiment discloses a turning and sleeve mechanism for bearing assembly.

[0044] A turning and sleeve-fitting mechanism for bearing assembly, comprising:

[0045] The feed plate assembly includes two symmetrically arranged feed plates 30, with a space formed between the two feed plates 30 for limiting and clamping the bearing outer ring 3;

[0046] The rotary cylinder 20 is mounted on the column 10 on the workbench and is used to drive the rotation of the feed plate group to reverse the bearing outer ring 3;

[0047] The ball-lifting tool is provided below the feed plate assembly and is used to receive the assembled roller 4 and lift the roller 4 to assemble it into the bearing outer ring 3;

[0048] The two feeding plates 30 are coaxially provided with avoidance holes 32 capable of accommodating the ball-pushing tooling to extend therein;

[0049] The feed plate group is further provided with a swing arm anti-slip component 60 , which faces the insertion space, contacts the bearing outer ring 3 , and limits the outer surface of the bearing outer ring 3 .

[0050] The above is the basic solution of this embodiment.

[0051] Specific reference Figure 1 As shown, in this embodiment, the feed plate assembly and the ball ejection tooling are arranged in upper and lower positions, a column 10 is provided on the workbench, a rotary cylinder 20 is fixed on the column 10, and the feed plate assembly is fixed on the rotary cylinder 20 via a mounting base 40, so that the rotary cylinder 20 can drive the feed plate assembly to rotate, thereby flipping the bearing outer ring 3 clamped in the inserted space;

[0052] In the front-end process, the ball 2 and the cage 1 are assembled into the roller 4, which is then transferred to the ball-lifting tooling. The ball-lifting tooling lifts the roller 4 and inserts it into the bearing outer ring 3 through the avoidance hole 32 on the feed plate 30, and then installs the roller 4 on the bearing outer ring 3.

[0053] It should be noted that, in this embodiment, two feed plates 30 are arranged at the upper and lower ends of the bearing outer ring 3, that is, the axial displacement of the bearing outer ring 3 is limited; however, the bearing outer ring 3 is still movable in the radial direction. Therefore, in this embodiment, a swing arm anti-slip assembly 60 is provided on the feed plate group to limit the radial displacement of the bearing outer ring 3, thereby ensuring that the bearing outer ring 3 will not fall from the insertion space during the flipping process.

[0054] The swing arm anti-slip assembly 60 is arranged on one of the feed plates 30 and extends into the insertion space, contacts the outer wall of the bearing outer ring 3, and has at least two limit points between it and the bearing outer ring 3. A triangle is formed between the two limit points and the axis of the bearing outer ring 3, thereby limiting the bearing outer ring 3.

[0055] In this embodiment, the specific implementation of the swing arm anti-slip assembly 60 is as follows: the swing arm anti-slip assembly 60 includes two sets of symmetrically arranged force blocks 61 and bearings 62 hinged to the force blocks 61;

[0056] The force block 61 is hinged on the feed plate 30 and can rotate around a first axis; the bearing 62 is rotatably arranged at a first end of the force block 61 close to a side where the force block is inserted into the space.

[0057] Specific reference Figure 2 As shown, the swing arm anti-slip assembly 60 is disposed on the side of one of the feed plates 30 and extends into the insertion space between the two feed plates 30;

[0058] It includes a force block 61 hinged to the end surface of the feed plate 30 via a short shaft. The first end of the force block 61 extends into the interior of the feed plate 30, and a bearing 62 is provided on this end for contacting and limiting the bearing outer ring 3.

[0059] The two bearings 62 are symmetrically arranged to symmetrically block the bearing outer ring 3 and limit the bearing outer ring 3 in the blocking direction.

[0060] Preferably, in order to enable the swing arm anti-slip assembly 60 to adapt to the shaking bearing outer ring 3, in this embodiment, the force block 61 is configured as an L-shaped structure, with the first axis located at the corner and the side away from the insertion space being the second end;

[0061] The two second ends are tightened and connected via an elastic member 63 .

[0062] Preferably, the elastic member 63 is a tension spring.

[0063] The two second ends are tightened by the tension spring, that is, the two second ends have a tendency to approach each other, so that the L-shaped force block 61 has a tendency to rotate in the opposite direction; therefore, the two first ends have a tendency to rotate outward in the opposite direction, so that the distance between the two first ends is as large as possible, so that the centers of the two bearings 62 form a larger angle with the center line of the bearing outer ring 3.

[0064] To avoid the distance between the two bearings 62 being too large, in this embodiment, a limiting groove 33 is provided on the feed plate 30 , and the first end and the bearing 62 are connected by a stop pin 64 , and the lower end of the stop pin 64 extends into the limiting groove 33 .

[0065] Specific reference Figure 2As shown, in this embodiment, on the feed plate 30 on which the swing arm anti-slip assembly 60 is installed, a shallow groove is provided on the end face on the same side as the swing arm anti-slip assembly 60 as a limiting groove 33, and the lower end of the stop pin 64 extends to the bottom of the force block 61 and extends into the limiting groove 33. The position of the stop pin 64 is limited by the limiting groove 33, thereby limiting the distance between the two bearings 62 to ensure the limiting effect of the swing arm anti-slip assembly 60.

[0066] In this embodiment, the feed plate 30 also has another direction of limitation on the bearing outer ring 3, and its specific limitation method is: a baffle 70 is provided on the side of the two feed plates 30 close to the column 10, and the swing arm anti-slip assembly 60 is located on the side opposite to the baffle 70.

[0067] Specific reference Figure 1 As shown, a stop bar 70 is provided on the inner side of the two feed plates 30, and the stop bar 70 and the swing arm anti-slip assembly 60 are respectively located on both sides of the insertion space. Thus, the stop bar 70 and the swing arm anti-slip assembly 60 limit the bearing outer ring 3 in the Y-axis direction;

[0068] In this embodiment, the feeding direction of the bearing 62 during assembly is the Z-axis direction. Therefore, a swing arm anti-slip assembly 60 is provided to limit the bearing outer ring 3 in the Z-axis direction. The two force blocks 61 are provided to be movable. The bearing outer ring 3 can be pushed out or pushed in along the Z-axis under the action of external force. During the assembly process, the bearing outer ring 3 cannot automatically slide out along the Z-axis, thereby ensuring the stability of the bearing outer ring 3 during the assembly process.

[0069] In this embodiment, a feeding platform 80 is further included. The feeding platform 80 is located below the feeding plate 30 and is used to receive the assembled roller 4.

[0070] The material transfer platform 80 is provided with a lifting hole capable of accommodating the lifting tool 50 to be raised and lowered.

[0071] Specific reference Figure 3 As shown, in this embodiment, the front-end process transfers the assembled roller 4 to the feeding platform 80, and the lifting platform 51 of the lifting tool 50 is embedded in the lifting hole, and the roller 4 is transferred to the lifting platform 51 through positioning;

[0072] The driving component drives the lifting rod of the lifting tool 50 to lift the lifting platform 51 upward, thereby lifting the roller 4 to the inside of the bearing outer ring 3 of the feed plate assembly.

[0073] In this embodiment, the specific implementation method for positioning and transferring the roller 4 is as follows: a ball pulling tool 90 is slidably provided on the upper end surface of the feeding platform 80 for positioning and transferring the roller 4;

[0074] The ball pulling tool 90 is provided with a pulling groove capable of accommodating the roller 4.

[0075] Specific reference Figure 4 and Figure 5 As described above, in this embodiment, the roller 4 is located in the drawing groove and moves along with the ball pulling tool 90. After the ball pulling tool 90 is loaded with the roller 4 in the previous process, it moves toward the side of the lifting platform 51 under the action of the driving component 6. At this time, the lifting platform 51 on the feeding platform 80 is embedded in the lifting hole or is located below the lifting hole. In the embedded state, the upper end surface of the lifting platform 51 is lower than the upper end surface of the feeding platform 80. The preferred height is that the height difference between the end surface of the lifting platform 51 and the end surface of the feeding platform 80 is the height of the roller 4;

[0076] When the ball pulling tool 90 moves to the feeding platform 80 and overlaps with the feeding platform 80, and the pulling groove position is coaxial with the lifting platform 51, the roller 4 falls into the lifting hole and is located on the lifting platform 51, thus completing the positioning and transfer of the roller 4;

[0077] At this time, the ball pulling tool 90 moves in the reverse direction to reset, and the lifting tool 50 can lift the roller 4.

[0078] In this embodiment, in order to confirm the state of the ball pulling tool 90 and determine the next stroke of the ball pulling tool 90, the ball pulling tool 90 is provided with a detection mechanism, and the detection mechanism is located on the side of the pulling groove.

[0079] Specific reference Figure 4 and Figure 5 As shown, in this embodiment, the detection mechanism is embedded in the ball pulling tool and is located on the side of the drawing groove, and detects in the direction of the drawing groove to determine whether there is a roller 4 in the drawing groove.

[0080] Preferably, in this embodiment, the detection mechanism uses two shooting switches 5. When there is a roller 4 in the pulling groove, the shooting of the two shooting switches 5 is blocked by the roller 4, thereby obtaining the information that there is a roller 4 in the pulling groove; when the roller 4 falls into the jacking groove, the shooting of the two shooting switches 5 is not blocked, thereby judging that there is no roller 4 in the pulling groove, and the driving component 6 drives the ball pulling tooling to move in reverse and exit the feeding platform 80.

[0081] In order to achieve unobstructed sensing of the two opposing beam switches 5 , in this embodiment, an opposing beam groove 91 is provided between the embedding groove and the pulling groove for inserting the opposing beam switch 5 .

[0082] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
