Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bearing production and assembly, in particular to a batch rapid assembly tool for bearings. BACKGROUND

[0002] As a core component for bearing mechanical rotation, bearings are widely used in high-speed motor trains and engineering machinery and other types of equipment, and the assembly precision and efficiency of bearings directly determine the running stability, transmission efficiency and service life of the equipment. Among them, rolling bearings have become the preferred bearing type for mechanical equipment with high performance requirements due to their small friction resistance, sensitive start-up, high mechanical efficiency, excellent precision retention and other outstanding advantages.

[0003] In the prior art, especially in the production scene of small batch and multiple varieties, the assembly of rolling bearings is usually carried out gradually and individually by using a production line. Specifically, the outer ring is placed eccentrically in the inner ring, then the balls are placed and clamped one by one in the raceway between the inner ring and the outer ring, and then the outer ring is pushed by a pressing rod to make the balls roll to realize the centering of the outer ring and the inner ring. The overall processing efficiency is low, which is not suitable for the large-scale and small-scale production of high-speed motor trains and precision machine tools and other equipment. SUMMARY

[0004] The present application provides a batch rapid assembly tool for bearings to solve the problem that the assembly of rolling bearings in the prior art is usually carried out gradually and individually by using a production line, and the overall processing efficiency is low, which is not suitable for small-scale production.

[0005] The present invention provides a rapid assembly fixture for batch assembly of bearings, which employs the following technical solution: A rapid assembly fixture for batch assembly of bearings is used for batch assembly of multiple bearings, wherein the bearing includes an inner ring, an outer ring, and multiple rollers; it includes a base, a positioning rod, and an assembly assembly; the positioning rod is arranged vertically and mounted on the base; multiple inner rings are sequentially sleeved on the positioning rod vertically; the outer ring is arranged in a one-to-one correspondence with the inner ring, and the outer ring is eccentrically arranged on the inner ring corresponding to it, with multiple rollers arranged between the outer ring and the inner ring corresponding to it; the assembly assembly includes a mounting shell, a push plate, and a lifting rod, wherein the mounting shell is placed on the base; the push plate is slidably mounted in the mounting shell through a first elastic element and can move towards or away from the outer ring along a first direction, the first elastic element along the first... The assembly is configured in two directions, with both the first and second directions being horizontal and perpendicular to each other. A push rod is provided on the push plate, and the push rod and lifting rod are both arranged along the first direction and side by side in the second direction. The lifting rod can be slidably mounted on the push plate along the second direction and can move up and down. In the initial state, both the push rod and the lifting rod are located at the bearings in contact with the base. As the push plate moves along the first direction toward the outer ring, the assembly has a first state and a second state. In the first state, both the push rod and the lifting rod abut against the outer ring, and the push rod can cause the outer ring to move in the second direction to be concentric with the inner ring. In the second state, the lifting rod drives the push rod and the push plate to move upward synchronously by a preset distance, which is the distance from one bearing to another.

[0006] Further, the two endpoints of the outer ring in the second direction are referred to as the first endpoint and the second endpoint, respectively. The push rod is located on one side of the first endpoint of the outer ring, and the lifting rod is located on one side of the second endpoint of the outer ring. One point where the extension line of the push rod in the first direction intersects the outer ring of the bearing to be assembled is referred to as the first point. The first point is located on the side of the first endpoint in the second direction closer to the positioning rod, and the first point is located on the side of the first endpoint in the first direction closer to the push plate. The extension line of the lifting rod in the first direction is tangent to the second endpoint of the outer ring of the bearing to be assembled.

[0007] Furthermore, the lifting rod is mounted on the push plate via a second elastic element, the second elastic element being arranged along a second direction, and the elastic coefficient of the first elastic element being greater than that of the second elastic element.

[0008] Furthermore, a roller is rotatably mounted on the end of the push rod near the bearing in the first direction, and the axis of rotation of the roller is set in the vertical direction.

[0009] Furthermore, the base is provided with two limiting rods, both of which are arranged vertically and side by side in the first direction. Both limiting rods are magnetic rods and can attract each other with the outer ring. The distance between the two limiting rods in the first direction is less than the diameter of the outer ring.

[0010] Furthermore, the lifting rod includes a first rod segment and a second rod segment, which are fixedly connected. The first rod segment is located on the side of the second rod segment closer to the push plate in a first direction. The first rod segment is arranged along the first direction and slidably mounted on the push plate. The second rod segment is inclined relative to the first rod segment.

[0011] Furthermore, the assembly also includes a drive rod located at the end of the mounting housing away from the bearing in a first direction and fixedly connected to the mounting housing, the drive rod being arranged along the first direction and capable of moving in the first direction.

[0012] Furthermore, the assembly also includes a drive arm, which is vertically positioned and rotatably mounted on the base, and a drive rod is rotatably connected to the drive arm and can move up and down relative to the drive arm.

[0013] Furthermore, a groove is provided on the drive arm, the groove is set in the vertical direction, and a rotating shaft passes through the groove, the drive rod and the rotating shaft are rotated together.

[0014] Furthermore, the assembly also includes a snap-fit ​​component, which is located between the mounting housing and the drive arm in the first direction. The snap-fit ​​component includes a snap block, a first snap plate, and a second snap plate. Both the first and second snap plates are fixedly mounted on the base in the vertical direction, and are arranged side by side in the second direction. The snap block is movable up and down between the first and second snap plates, and the drive rod passes through the snap block in the first direction. The first snap plate has multiple first slots in the vertical direction, and the second snap plate has multiple second slots in the vertical direction. The first and second slots are arranged in a one-to-one correspondence, and the first and corresponding second slots are arranged side by side in the second direction. Both ends of the snap block in the second direction are connected to snap protrusions by a third elastic element. The two snap protrusions can engage with the first and corresponding second slots, respectively.

[0015] The beneficial effects of this invention are as follows: The bearing mass rapid assembly fixture of this invention uses a positioning rod and assembly components to coordinate. Multiple bearing inner and outer rings are stacked on the positioning rod. The movement of the push plate realizes the switching of the bearing to be assembled by the lifting rod, and the push rod pushes the outer ring, ultimately making the outer and inner rings of the bearing concentric, thus completing the assembly of the bearing. This process can be repeated to realize the continuous assembly of multiple bearings, eliminating the need for step-by-step assembly. It can be adapted to the large-scale production needs of equipment such as high-speed trains and precision machine tools. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] An embodiment of the present invention provides a rapid assembly tooling for mass production of bearings, such as... Figures 1 to 13 As shown.

[0021] A rapid assembly fixture for batch assembly of bearings is provided for assembling multiple bearings 100 in batches. Each bearing 100 includes an inner ring 120, an outer ring 110, and multiple rollers 130. The rapid assembly fixture includes a base 200, a positioning rod 300, and an assembly assembly 400. The positioning rod 300 is vertically positioned and fixedly mounted on the base 200. Multiple inner rings 120 are sequentially fitted onto the positioning rod 300 vertically. The outer rings 110 are arranged in a one-to-one correspondence with the inner rings 120, with the outer rings 110 eccentrically positioned on their corresponding inner rings 120. Multiple rollers 130 are arranged between the outer rings 110 and their corresponding inner rings 120.

[0022] Assembly assembly 400 and positioning rod 300 are sequentially arranged in a first direction. Assembly assembly 400 includes mounting housing 410, push plate 420, and lifting rod 430. Mounting housing 410 is placed on base 200. Push plate 420 is slidably mounted in mounting housing 410 via first elastic member 440 and can move towards or away from outer ring 110 in the first direction. First elastic member 440 is arranged in a second direction and is a spring. Both the first and second directions are horizontal and perpendicular to each other. Push rod 450 is provided on push plate 420. Push rod 450 and lifting rod 430 are both arranged in the first direction and arranged side by side in the second direction. Lifting rod 430 is slidably mounted on push plate 420 in the second direction and can move up and down.

[0023] In the initial state, both push rod 450 and lifting rod 430 are located at the bearing 100 in contact with the base 200. During the movement of push plate 420 towards the outer ring 110 in the first direction, assembly assembly 400 has a first state and a second state. In the first state, both push rod 450 and lifting rod 430 abut against the outer ring 110, and push rod 450 causes the outer ring 110 to move in the second direction until it is concentric with the inner ring 120. In the second state, lifting rod 430 drives push rod 450 and push plate 420 to move synchronously upwards by a preset distance, which is the distance from one bearing 100 to another bearing 100.

[0024] In this embodiment, by setting up a positioning rod 300 and an assembly assembly 400 to cooperate, during use, the inner rings 120 of multiple bearings 100 are sequentially fitted onto the positioning rod 300, and then multiple outer rings 110 are sequentially fitted onto their corresponding inner rings 120, with the outer rings 110 and their corresponding inner rings 120 eccentrically positioned to ensure that a pre-installed gap for rollers 130 is left between the inner rings 120 and the outer rings 110. Then, rollers 130 are placed between each outer ring 110 and its corresponding inner ring 120. Since the number of rollers 130 that can be installed between the inner ring 120 and the outer ring 110 of each bearing 100 is fixed, there will be no situation where some bearings 100 have more rollers 130 than others during installation, and there will be no deviation in the number of rollers 130.

[0025] At this time, push rod 450 and lifting rod 430 are both located at the bearing 100 that abuts against the base 200, that is, at the lowest bearing 100. For ease of explanation, this bearing 100 is referred to as the first bearing 101. Then, push plate 420 is moved in the first direction toward the outer ring 110 of the first bearing 101. During the movement of push plate 420, push rod 450 and lifting rod 430 will gradually approach and abut against the outer ring 110 of the first bearing 101. Then, push rod 450 will cause the outer ring 110 of the first bearing 101 to move in the second direction until the outer ring 110 is concentric with the inner ring 120. During the movement of the outer ring 110, the inner ring 120 is fixed by the positioning rod 300. The roller 130 between the outer ring 110 and the inner ring 120 rolls, completing the assembly of the first bearing 101. At this time, assembly assembly 400 is in the first state. Then, the push plate 420 is moved away from the outer ring 110 in the first direction to reset. After that, the push plate 420 is moved again in the first direction towards the outer ring 110. At this time, the first bearing 101 and the other bearings 100 above it will be misaligned. During the movement of the push plate 420, the push rod 450 and the lifting rod 430 will gradually approach the outer ring 110 of the first bearing 101. After the lifting rod 430 abuts against the outer ring 110 of the first bearing 101, the lifting rod 430 will move up a preset distance along the outer ring 110 of the first bearing 101. The upward movement of the lifting rod 430 will drive the push rod 450 and the push plate 420 to move up synchronously, so that the lifting rod 430 comes to the other bearing 100 above the first bearing 101. For ease of explanation, the other bearing 100 above the first bearing 101 is referred to as the second bearing 102. As the push plate 420 continues to move, the push rod 450 will cause the outer ring 110 of the second bearing 102 to move in the second direction until the outer ring 110 is concentric with the inner ring 120, thus completing the assembly of the second bearing 102, and this cycle continues until the assembly of all bearings 100 is completed.

[0026] In this embodiment, multiple bearings 100 with inner rings 120 and outer rings 110 are stacked on the positioning rod 300. The lifting rod 430 is used to switch the bearings 100 to be assembled by moving the push plate 420, and the push rod 450 pushes the outer ring 110. Finally, the outer ring 110 and inner ring 120 of the bearing 100 are made concentric, and the assembly of the bearing 100 is completed. This process can be repeated to achieve continuous assembly of multiple bearings 100, eliminating the need for step-by-step assembly. This method can meet the large-scale production needs of equipment such as high-speed trains and precision machine tools.

[0027] In a further embodiment, the two endpoints of the outer ring 110 in the second direction are referred to as the first endpoint and the second endpoint, respectively. The push rod 450 is located on the side of the first endpoint of the outer ring 110, and the lifting rod 430 is located on the side of the second endpoint of the outer ring 110. One point where the extension line of the push rod 450 in the first direction intersects the outer ring 110 of the bearing 100 to be assembled is referred to as the first point. The first point is located on the side of the first endpoint closer to the positioning rod 300 in the second direction, and the first point is also located on the side of the first endpoint closer to the push plate 420 in the first direction. The extension line of the lifting rod 430 in the first direction is tangent to the second endpoint of the outer ring 110 of the bearing 100 to be assembled.

[0028] The lifting rod 430 is mounted on the push plate 420 via the second elastic element 434. The second elastic element 434 is arranged along the second direction and is a spring. The elastic coefficient of the first elastic element 440 is greater than that of the second elastic element 434.

[0029] When assembling the bearing 100 (first bearing 101) to be assembled, by positioning the first point on the side of the first endpoint closer to the positioning rod 300 in the second direction, and making the extension line of the lifting rod 430 in the first direction tangent to the second endpoint, the push plate 420 is pushed towards the side closer to the outer ring 110 of the first bearing 101. When the push rod 450 moves to abut against the first point, the push rod 450 will move along the outer ring 110; and the lifting rod 430 is elastically mounted on the push plate 420. And make the elastic coefficient of the first elastic element 440 greater than the elastic coefficient of the second elastic element 434, so that when the push rod 450 and the lifting rod 430 both abut against the outer ring 110 of the bearing 100, as the push rod 450 moves along the outer ring 110 and causes the outer ring 110 to move in the second direction, the first elastic element 440 can restrict the push rod 450 from being pushed in the opposite direction by the outer ring 110, and the lifting rod 430 can maintain abutment against the outer ring 110 and compress the second elastic element 434 during the movement of the outer ring 110.

[0030] In a further embodiment, a roller 451 is rotatably provided at the end of the push rod 450 near the bearing 100 in the first direction, and the rotation axis of the roller 451 is arranged in the vertical direction.

[0031] By setting up roller 451, the outer ring 110 of bearing 100 is pushed during assembly, thereby reducing the friction between the two.

[0032] In a further embodiment, the base 200 is provided with two limiting rods 500. Both limiting rods 500 are vertically aligned and arranged side-by-side in a first direction. Both limiting rods 500 are magnetic rods and can attract each other to the outer ring 110. The distance between the two limiting rods 500 in the first direction is less than the diameter of the outer ring 110. The difference between the diameter of the outer ring 110 and the distance between the two limiting rods 500 in the first direction is referred to as D, where 1cm ≤ D ≤ 3cm, and D is a positive integer.

[0033] By setting two magnetic limit rods 500, the outer ring 110 is restricted between the two limit rods 500, thereby positioning the outer ring 110.

[0034] In a further embodiment, the lifting rod 430 includes a first rod segment 431 and a second rod segment 432, which are fixedly connected. The first rod segment 431 is located on the side of the second rod segment 432 that is close to the push plate 420 in a first direction. The first rod segment 431 is arranged along the first direction and is slidably mounted on the push plate 420 via a sliding plate 433. The second rod segment 432 is inclined relative to the first rod segment 431.

[0035] After the first bearing 101 is assembled, the push plate 420 is moved and reset in the first direction away from the outer ring 110. At this time, the first bearing 101 and the other bearings 100 located above it will be misaligned. See [link / reference needed]. Figure 9 and Figure 10 As shown. Then, the push plate 420 is moved in the first direction towards the outer ring 110. During the movement of the push plate 420, the push rod 450 and the lifting rod 430 will gradually approach the outer ring 110 of the first bearing 101.

[0036] See Figure 11 As shown, for ease of explanation, the point where the extension line of the lifting rod 430 in the first direction intersects with the outer ring 110 of the assembled bearing 100 (first bearing 101) is called the second point. After the lifting rod 430 abuts against the second point, the second segment 432 of the lifting rod 430 will move upward along the outer ring 110 of the first bearing 101 to the upper end face of the first bearing 101, so that the second segment 432 comes to the outer ring 110 of the second bearing 102, and the first segment 431 abuts against the upper end face of the first bearing 101. As the push plate 420 continues to move, the push rod 450 will cause the outer ring 110 of the second bearing 102 to move in the second direction until the outer ring 110 is concentric with the inner ring 120, completing the assembly of the second bearing 102. See [link to documentation]. Figure 12 and Figure 13 As shown.

[0037] In a further embodiment, the assembly 400 also includes a drive rod 460, which is located at the end of the mounting housing 410 away from the bearing 100 in a first direction and is fixedly connected to the mounting housing 410. The drive rod 460 is arranged along the first direction and is movable in the first direction.

[0038] The assembly component 400 also includes a drive arm 470, which is arranged vertically and rotatably mounted on the base 200. The drive rod 460 is rotatably connected to the drive arm 470 and can move up and down relative to the drive arm 470.

[0039] Specifically, a slide groove is provided on the drive arm 470, the slide groove is arranged in the vertical direction, a rotating shaft is inserted in the slide groove, the rotating shaft is arranged in the second direction and a limit plate is provided at both ends of the rotating shaft, the limit plate is used to prevent the rotating shaft from coming out of the slide groove, and the drive rod 460 is in rotational cooperation with the rotating shaft.

[0040] In this embodiment, by setting up a drive rod 460 and a drive arm 470, during assembly, the operator holds the drive arm 470 and rotates the drive arm 470 around the second direction. See [reference needed]. Figure 2 As shown, when the drive arm 470 rotates upward in the second direction, it will give the drive rod 460 an upward force through the rotating shaft, thereby causing the drive rod 460 to drive the mounting housing 410 to move in the first direction, and then the mounting housing 410 will drive the push rod 450 and the lifting rod 430 on the push plate 420 to move.

[0041] In a further embodiment, the assembly assembly 400 further includes a snap-fit ​​member 480, which is located between the mounting housing 410 and the drive arm 470 in a first direction. The snap-fit ​​member 480 includes a snap block 481, a first snap plate 484, and a second snap plate 486. The first snap plate 484 and the second snap plate 486 are both fixedly mounted on the base 200 in a vertical direction, and are arranged side by side in a second direction. The snap block 481 is movably mounted between the first snap plate 484 and the second snap plate 486, and the drive rod 460 passes through the snap block 481 in the first direction. The first snap plate 484 has a plurality of first snap slots 485 in a vertical direction, and the second snap plate 486 has a plurality of second snap slots 487 in a vertical direction. The first snap slots 485 and the second snap slots 487 are arranged in a one-to-one correspondence, and the first snap slots 485 and their corresponding second snap slots 487 are arranged side by side in a second direction. Both ends of the locking block 481 in the second direction are connected to locking protrusions 483 via third elastic members 482, which are springs. The two locking protrusions 483 can respectively engage with the first locking slot 485 and the second locking slot 487 corresponding to the first locking slot 485. The preset distance is the distance between two adjacent first locking slots 485 in the vertical direction.

[0042] In this embodiment, by setting up a snap-fit ​​component 480, when the first bearing 101 is assembled and the second bearing 102 is assembled, as the second segment 432 of the lifting rod 430 moves up along the outer ring 110 of the first bearing 101 to the upper end surface of the first bearing 101, the second segment 432 will also drive the mounting shell 410 and the push rod 450 to move up through the push plate 420, and drive the drive rod 460 to move up through the mounting shell 410. The upward movement of the drive rod 460 will drive the snap-fit ​​block 481 to move up synchronously, thereby causing the snap-fit ​​protrusion 483 on the snap-fit ​​block 481 to retract under force. When the second segment 432 reaches the outer ring 110 of the second bearing 102, the two snap-fit ​​protrusions 483 will respectively snap into another first snap-fit ​​groove 485 and a second snap-fit ​​groove 487 corresponding to the first snap-fit ​​groove 485. By engaging the protrusion 483 with the first slot 485 and the second slot 487, the vertical positions of the drive rod 460, mounting housing 410, push plate 420, and lifting rod 430 are restricted when assembling multiple bearings 100, thereby improving assembly stability.

[0043] Based on the above embodiments, the specific working process is as follows: In use, the inner rings 120 of multiple bearings 100 are sequentially fitted onto the positioning rod 300, and then the outer rings 110 are sequentially fitted onto their corresponding inner rings 120, with the outer rings 110 and their corresponding inner rings 120 eccentrically positioned to ensure that a clearance for the installation of rollers 130 is reserved between the inner rings 120 and the outer rings 110. Then, rollers 130 are placed between each outer ring 110 and its corresponding inner ring 120. Since the number of rollers 130 that can be installed between the inner ring 120 and the outer ring 110 of each bearing 100 is fixed, there will be no situation where some bearings 100 have more rollers 130 than others, and there will be no deviation in the number of rollers 130.

[0044] At this time, both push rod 450 and lifting rod 430 are located at the first bearing 101. Then, the operator holds the drive arm 470 and rotates the drive arm 470 around the second direction. (See below) Figure 2 As shown, when the drive arm 470 rotates upward in the second direction, it will give the drive rod 460 an upward force through the rotating shaft, thereby causing the drive rod 460 to drive the mounting housing 410 to move in the first direction, and then the mounting housing 410 will drive the push rod 450 and the lifting rod 430 on the push plate 420 to move.

[0045] During the movement of the push plate 420, the push rod 450 and the lifting rod 430 will gradually approach and abut against the outer ring 110 of the first bearing 101. When the push rod 450 moves to abut against the first point, the push rod 450 will move along the outer ring 110. The lifting rod 430 is mounted on the push plate 420 by the second elastic element, and the elastic coefficient of the first elastic element 440 is greater than the elastic coefficient of the second elastic element 434. Thus, when both the push rod 450 and the lifting rod 430 abut against the outer ring 110 of the bearing 100, during the movement of the push rod 450 along the outer ring 110 and the movement of the outer ring 110 in the second direction, the first elastic element 440 can restrict the push rod 450 from being pushed in the opposite direction by the outer ring 110, and the lifting rod 430 can maintain abutment against the outer ring 110 and compress the second elastic element 434 during the movement of the outer ring 110. During the process of the outer ring 110 being pushed and moved, the inner ring 120 is restricted to remain stationary by the positioning rod 300, and the roller 130 between the outer ring 110 and the inner ring 120 rolls to complete the assembly of the first bearing 101. At this time, the assembly assembly 400 is in the first state.

[0046] Then, the push plate 420 is moved back to its original position in the first direction away from the outer ring 110. Afterward, the push plate 420 is moved again in the first direction towards the outer ring 110. At this point, the first bearing 101 and the other bearings 100 located above it will be misaligned. (See [reference]). Figure 9 and Figure 10 As shown. Then, the push plate 420 is moved in the first direction towards the outer ring 110. During the movement of the push plate 420, the push rod 450 and the lifting rod 430 will gradually approach the outer ring 110 of the first bearing 101.

[0047] See Figure 11 As shown, for ease of explanation, the point where the extension line of the lifting rod 430 in the first direction intersects with the outer ring 110 of the assembled bearing 100 (first bearing 101) is called the second point. After the lifting rod 430 abuts against the second point, the second segment 432 of the lifting rod 430 will move upward along the outer ring 110 of the first bearing 101 to the upper end face of the first bearing 101, so that the second segment 432 comes to the outer ring 110 of the second bearing 102, and the first segment 431 abuts against the upper end face of the first bearing 101. As the push plate 420 continues to move, the push rod 450 will cause the outer ring 110 of the second bearing 102 to move in the second direction until the outer ring 110 is concentric with the inner ring 120, completing the assembly of the second bearing 102. See [link to documentation]. Figure 12 and Figure 13 As shown.

[0048] Furthermore, when the first bearing 101 is assembled and the second bearing 102 is assembled, as the second segment 432 of the lifting rod 430 moves upward along the outer ring 110 of the first bearing 101 to the upper end surface of the first bearing 101, the second segment 432 will also drive the mounting shell 410 and the push rod 450 to move upward through the push plate 420, and drive the drive rod 460 to move upward through the mounting shell 410. The upward movement of the drive rod 460 will drive the locking block 481 to move upward synchronously, thereby causing the locking protrusion 483 on the locking block 481 to retract under force. When the second segment 432 reaches the outer ring 110 of the second bearing 102, the two locking protrusions 483 will respectively engage with another first locking groove 485 and a second locking groove 487 corresponding to the first locking groove 485. By engaging the protrusion 483 with the first slot 485 and the second slot 487, the vertical positions of the drive rod 460, mounting housing 410, push plate 420, and lifting rod 430 are restricted when assembling multiple bearings 100, thereby improving assembly stability.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
