[0039] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain the present invention and do not limit the present invention.

[0040] As Figures 1 to 6 shown, the present invention provides a bearing assembly device 100, including

[0041] an assembly device 10 for carrying a cage 50 and aligning a clamping position 51 on the cage 50 with the outlet of a feeding channel 22 for rolling elements;

[0042] a pressing device 20, including at least one of the feeding channels 22, a pressing member 23 that can penetrate the side wall of the feeding channel 22 to open or close the feeding channel 22, and a first driving assembly for driving the pressing member 23 to move; when the first driving assembly drives the pressing member 23 to open the feeding channel 22, the rolling elements move onto the clamping position 51 of the cage 50 under the action of gravity; when the first driving assembly drives the pressing member 23 to close the feeding channel 22, the pressing member 23 presses the rolling elements on the clamping position 51 into the clamping position 51 of the cage 50.

[0043] Specifically, a bearing is composed of an inner bearing ring, an outer bearing ring, a cage 50, and rolling elements. The rolling elements are used to maintain rolling between the inner bearing ring and the outer bearing ring, reducing the friction between the inner bearing ring and the outer bearing ring. The cage 50 is used to fix the rolling elements so that the rolling elements are independent of each other and avoid interference.

[0044] When performing the overall assembly of the bearing, it is first necessary to complete the assembly between the steel balls and the cage 50 to fix the steel balls. Among them, the rolling elements are spherical rolling elements, such as steel balls, etc. The cage 50 is an annular cylinder 52 or an annular prism. The annular cylinder 52 or the annular prism is provided with a plurality of clamping positions 51. The clamping positions 51 are used to fix the rolling bodies so that the rolling bodies and the clamping positions 51 form a whole. The clamping position 51 is composed of a through hole opened on the body of the annular cylinder 52 or the annular prism and limiting members fixedly connected to both ends of the through hole. The height of the annular cylinder 52 or the annular prism is less than the height of the rolling body, so that the rolling body can protrude from both ends of the through hole. The term "a plurality" in this application refers to two or more.

[0045] The bearing assembly device 100 includes an assembly device 10. The assembly device 10 is used to carry the cage 50 and make the clamping position 51 on the cage 50 correspond to the outlet of the feeding channel 22 for rolling elements during the process of carrying the cage 50, so as to ensure that the rolling elements in the feeding channel 22 can fall onto the clamping position 51 of the cage 50 under the action of gravity, facilitating the next operation on the rolling elements.

[0046] The pressing device 20 includes a cylindrical pressing body 21. Using a cylindrical pressing body 21 can reduce costs while ensuring the stable installation of other components. Of course, according to the design requirements, a pressing body 21 of other shapes can also be used, such as a cuboid or cube structure, etc., which will not be elaborated here one by one. The pressing body 21 is made of aluminum alloy material. The pressing body 21 made of aluminum alloy material has advantages such as strong supporting force and wear resistance. Of course, according to the design requirements, other materials can also be used to achieve different characteristics, such as plastic materials, wood materials, etc.

[0047] At least one feeding channel 22 is formed on the pressing body 21. The horizontal height of the feeding port of the feeding channel 22 is greater than the horizontal height of the discharging port of the feeding channel 22 to ensure that the steel balls can move from the feeding port of the feeding channel 22 to the discharging port under the action of gravity. In this application, the feeding channel 22 is preferably arranged along the direction of gravity to ensure that the rolling elements can quickly pass through the feeding channel 22.

[0048] An extrusion member 23 is also installed on the pressing body 21. The extrusion member 23 is a cylinder 52 or a prism. The extrusion member 23 penetrates through the side wall of the feeding channel 22 to open or close the feeding channel 22. One end of the extrusion member 23 is connected with a first driving assembly for driving the extrusion member 23 to move, so as to open or close the feeding channel 22.

[0049] The operation process is as follows: First, place the cage 50 on the assembling device 10. At this time, the engaging position 51 on the cage 50 of the assembling device 10 is aligned with the discharging port of the feeding channel 22 of the rolling elements. When the first driving assembly drives the extrusion member 23 to open the feeding channel 22, the rolling elements move onto the engaging position 51 of the cage 50 under the action of gravity. When the first driving assembly drives the extrusion member 23 to close the feeding channel 22, the extrusion member 23 extrudes the rolling elements on the engaging position 51 into the engaging position 51 of the cage 50, completing the assembly between the rolling elements and the cage 50.

[0050] Adopting the above technical solution, the rolling elements are extruded into the engaging position 51 of the cage 50 by the extrusion member 23 that horizontally penetrates the feeding channel 22, shortening the height of the equipment in the longitudinal direction. The bearing assembling device 100 omits the pre-installer in the existing equipment, reducing the volume of the equipment and simplifying the structure of the equipment. Due to the omission of the pre-installer, the assembling time is shortened, thus further improving the installation efficiency.

[0051] In an embodiment of the present application, the first driving assembly includes:

[0052] A first driving member 261; and

[0053] The transmission member 262 is connected to the output shaft of the first driving member 261, and at least one of the pressing members 23 is movably connected to the transmission member 262. The transmission member 262 drives the pressing member 23 to open or close the feeding channel 22.

[0054] Specifically, the first driving member 261 is a first telescopic cylinder, and one end of the first telescopic cylinder with a telescopic shaft is connected to the pressing body 21. In this embodiment, one end of the first telescopic cylinder with a telescopic shaft is connected to the top of the pressing body 21, and the output shaft of the first telescopic cylinder extends into the pressing body 21 and can move up and down inside the pressing body 21.

[0055] An accommodating cavity is provided inside the pressing body 21. The transmission member 262 is a cone or frustum with an inclined surface. The transmission member 262 is arranged in the accommodating cavity and connected to the telescopic shaft of the first telescopic cylinder. The transmission member 262 moves up and down in the cavity following the telescopic shaft of the first telescopic cylinder.

[0056] The transmission member 262 is movably connected to the telescopic shaft of the first telescopic cylinder. By using a movable connection method, it is convenient for later maintenance when the transmission member 262 is abnormal. Of course, according to the design requirements, a fixed connection method can also be used. By using a fixed connection method, the stability of the connection between the transmission member 262 and the output shaft of the first telescopic cylinder can be ensured, providing a stable working environment for the transmission member 262.

[0057] The end of at least one pressing member 23 is movably connected to the transmission member 262 and can move following the transmission member 262 to open or close the feeding channel 22. Specifically, when the first telescopic cylinder moves downward, the transmission member 262 drives the pressing member 23 to open the feeding channel 22; when the first telescopic cylinder moves upward, the transmission member 262 drives the pressing member 23 to close the feeding channel 22. Of course, it can also be that when the first telescopic cylinder moves upward, the transmission member 262 drives the pressing member 23 to open the feeding channel 22; when the telescopic cylinder moves downward, the transmission member 262 drives the pressing member 23 to close the feeding channel 22.

[0058] In another embodiment of the present application, the first driving member 261 can also be a rotating motor, and one end of the rotating motor with a rotating shaft is connected to the pressing body 21. In this embodiment, one end of the rotating motor with a rotating shaft is connected to the top of the pressing body 21, and the rotating shaft of the rotating motor extends into the pressing body 21 and can rotate clockwise or counterclockwise inside the pressing body 21.

[0059] There is a receiving cavity inside the pressing body 21. The transmission member 262 is a gear, which is arranged in the receiving cavity and connected to the rotating shaft of the rotating motor. The transmission member 262 rotates clockwise or counterclockwise in the receiving cavity following the rotating shaft of the rotating motor.

[0060] The transmission member 262 is movably connected to the rotating shaft of the rotating motor. By adopting the way of movable connection, when the transmission member 262 fails, it is convenient to replace the transmission member 262 and facilitate the later maintenance. Of course, according to the design requirements, it can also be connected in a fixed connection way. By adopting the fixed connection way, the stability of the connection between the transmission member 262 and the output shaft of the rotating motor can be ensured, and a stable working environment can be provided for the transmission member 262.

[0061] At least one end of the extrusion member 23 is movably connected to the transmission member 262. At this time, the side of the extrusion member 23 in contact with the transmission member 262 is gear-shaped. When there are more than two extrusion members 23, the parts of each extrusion member 23 in contact with the transmission member 262 are not at the same height and can move along with the transmission member 262 to open or close the feed channel 22. Specifically, when the rotating motor rotates clockwise, the transmission member 262 drives the extrusion member 23 to open the feed channel 22; when the rotating motor rotates counterclockwise, the transmission member 262 drives the extrusion member 23 to close the feed channel 22. Of course, it can also be that when the rotating motor rotates clockwise, the transmission member 262 drives the extrusion member 23 to open the feed channel 22; when the rotating motor rotates counterclockwise, the transmission member 262 drives the extrusion member 23 to close the feed channel 22.

[0062] By adopting the above technical solution, the movement of multiple extrusion members 23 is synchronously controlled by the transmission member 262, which improves the assembly efficiency of the bearing assembly equipment 100.

[0063] In an embodiment of the present application, the transmission member 262 is a cone, and the movement direction of the cone under the action of the first driving member 261 is perpendicular to the plane where the retainer 50 is located;

[0064] The extrusion member 23 is movably connected to the outer wall of the cone, and drives the extrusion member 23 to open or close the feed channel 22 as the radius changes when the cone moves.

[0065] Specifically, the transmission member 262 is a cone. Under the action of the first driving member 261, the movement direction of the cone is perpendicular to the plane where the retainer 50 is located. The extrusion member 23 is movably connected to the outer wall of the cone, so as to drive the extrusion member 23 to open or close the feed channel 22 as the radius changes when the cone moves.

[0066] With the above technical solution, since the outer wall of the cone has a consistent inclination angle, the pressing members 23 movably connected to the outer wall of the cone move synchronously, facilitating the control of one or more pressing members 23 and improving the synchronization and accuracy of assembly.

[0067] In an embodiment of the present application, the pressing member 23 is rod-shaped, and a return spring 24 is sleeved thereon. One end of the return spring 24 abuts against one end of the pressing member 23 close to the transmission member 262, and the other end abuts against the outer wall of the feeding channel 22.

[0068] Specifically, the pressing member 23 is rod-shaped, and a return spring 24 is sleeved on the pressing member 23. One end of the return spring 24 abuts against one end of the pressing member 23 close to the transmission member 262, and the other end abuts against the outer wall of the feeding channel 22. The opening or closing of the feeding channel 22 by the pressing member 23 is achieved through the mutual cooperation of the return spring 24 and the transmission member 262, with a simple structure and easy maintenance.

[0069] In an embodiment of the present application, the pressing member 23 can pass through one end of the feeding channel 22, and the side thereof facing the retainer 50 is a bevel or an arc surface.

[0070] With the above technical solution, one end of the pressing member 23 that can pass through the feeding channel 22 is provided with a bevel or an arc surface on the side facing the retainer 50, which facilitates the pressing member 23 to press the rolling element into the clamping position 51 on the retainer 50 when closing the feeding channel 22, with a smaller pressing resistance and an increased pressing speed.

[0071] In an embodiment of the present application, the radius of the end of the cone away from the retainer 50 is smaller than that of the end close to the retainer 50.

[0072] Specifically, the radius of the end of the cone away from the retainer 50 is smaller than the radius of the end close to the retainer 50. When the cone moves downward, the pressing member 23 is slidably connected to the outer side wall of the cone, and at this time, the pressing member 23 gradually opens the feeding channel 22; when the cone moves upward, the pressing member 23 gradually closes the feeding channel 22.

[0073] With the above technical solution, the moving space between the transmission member 262 and the pressing member 23 is widened, facilitating mechanical operation.

[0074] In an embodiment of the present application, it further includes a second driving member 30 connected to the pressing device 20 and driving the pressing device 20 to approach or move away from the assembling device 10.

[0075] Specifically, the second driving member 30 is a second telescopic cylinder. The telescopic shaft of the second driving member 30 is fixedly connected to the pressing device 20. By using the fixed connection method, the connection stability between the second driving member 30 and the pressing device 20 is ensured. Of course, it can be conceived that the second driving member 30 and the pressing device 20 can also be connected in a movable connection manner. By using the movable connection method, it is convenient for later maintenance and disassembly. The pressing device 20 is driven by the second driving member 30 to approach or move away from the assembling device 10. After the rolling elements and the cage 50 are assembled, it is convenient to take out the assembled rolling elements and the cage 50.

[0076] In an embodiment of the present application, a limiting member is further provided between the second driving member 30 and the pressing device 20. The limiting member is used to limit the relative rotation between the second driving member 30 and the pressing device 20.

[0077] Specifically, a limiting member is further provided between the second driving member 30 and the pressing device 20. The limiting member includes a limiting column 41 fixedly connected to the second driving member 30 and a limiting ring 42 fixedly connected to the fixing device. The fixing column is always sleeved in the limiting ring 42. When the second driving member 30 drives the pressing device 20 to approach or move away from the assembling device 10, the limiting column 41 always slides in the limiting ring 42, thereby preventing the rotation between the second driving member 30 and the pressing device 20, and ensuring that the feeding channel 22 on the pressing device 20 always moves in the same direction.

[0078] In an embodiment of the present application, a hopper 25 for storing rolling elements is further included. The bottom of the hopper 25 includes at least one feeding channel 22.

[0079] Specifically, a baffle is provided around the top of the pressing body 21. The baffle is closed to form the hopper 25. The bottom of the hopper 25 includes at least one feeding channel 22. During processing, a certain number of rolling elements are added into the hopper 25. Under the action of gravity, the rolling elements automatically fall into the feeding channel 22, eliminating the need for frequent material addition and reducing the operation process.

[0080] In an embodiment of the present application, the assembling device 10 includes:

[0081] An assembling platform 11 for supporting the cage 50; and

[0082] A feeding assembly for conveying the cage 50 to the assembling platform 11.

[0083] Specifically, the assembly device 10 includes an assembly platform 11 made of aluminum alloy material. The assembly platform 11 made of aluminum alloy material has the advantage of strong supporting ability. Of course, it can also be made of other materials, such as wood material. The assembly platform 11 made of wood material has advantages such as earthquake resistance. By sending the retainer 50 to the assembly platform 11 through the feeding component, the alignment accuracy between the retainer 50 and the feeding channel 22 can be improved, realizing automated operation and improving production efficiency.

[0084] In an embodiment of the present application, a guiding groove 111 for the feeding component to pass through is provided on the assembly platform 11.

[0085] The feeding device is guided through the guiding groove 111 provided on the assembly platform 11, improving the alignment between the feeding component and the assembly platform 11. The structure is simple, improving the alignment accuracy and efficiency, and at the same time facilitating the movement of the assembly platform 11.

[0086] In an embodiment of the present application, the feeding component includes:

[0087] A support platform 121 located in the guiding groove 111 for supporting the retainer 50;

[0088] A supporting platform 122 for supporting the support platform 121;

[0089] A third driving member 123 connected to the supporting platform 122 for driving the supporting platform 122 to reciprocate along the extending direction of the guiding groove 111; and

[0090] A fourth driving member 124 connected to the supporting platform 122 for driving the support platform 121 to move up and down along the guiding groove 111.

[0091] Specifically, the support platform 121 is located in the guiding groove 111 and is used to support the retainer 50. The supporting platform 122 is arranged at the bottom of the support platform 121. A support channel is provided on the supporting platform 122 from the top to the bottom of the supporting platform 122. The fourth driving member 124 is a telescopic cylinder. The telescopic shaft of the fourth driving member 124 passes through the support through hole and is connected to the support platform 121. The fourth driving member 124 drives the support platform 121 to move up and down relative to the supporting platform 122. A third driving member 123 is also provided on the side of the supporting platform 122. The third driving member 123 drives the supporting platform 122 to move along the extending direction of the guiding groove 111.

[0092] Its working process is as follows: The fourth driving member 124 drives the support platform 121 to protrude from the assembly platform 11. At this time, the retainer 50 is placed on the support platform 121, and the placement is completed. The third driving member 123 drives the supporting platform 122 to move along the extension direction of the guiding groove 111. When the retainer 50 moves below the pressing device 20, the fourth driving member 124 drives the support platform 121 to descend, so that the height of the support platform 121 is less than the height of the assembly platform 11. At this time, the retainer 50 is placed on the assembly platform 11.

[0093] Adopting the above technical solution facilitates the alignment of the retainer 50 with the feeding channel 22 and also facilitates the transmission of the retainer 50.

[0094] In an embodiment of the present application, a positioning member 1211 is provided on the support platform 121 to align the upper clamping position 51 on the retainer 50 with the discharge port of the feeding channel 22.

[0095] Setting the positioning member 1211 on the support platform 121 prevents the retainer 50 from being displaced during transportation. Through the positioning member 1211, the clamping position 51 on the retainer 50 is aligned with the discharge port of the feeding channel 22, improving the alignment accuracy.

[0096] In an embodiment of the present application, a guiding column 211 is provided on the side of the pressing device 20 facing the assembly platform 11, and a guiding hole 112 matching the guiding column 211 is provided on the support platform 121. When the pressing device 20 approaches the assembling device 10, the guiding column 211 is inserted into the guiding hole 112.

[0097] Adopting the above technical solution prevents the pressing device 20 and the support platform 121 from being displaced during the working process, improving the stability during assembly.

[0098] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the specification and drawings of the present invention under the inventive concept of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
