Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

The ball fitting device provided in the embodiment of the present invention is described below with reference to fig. 1 to 13.

Specifically, the ball assembling device comprises a base 1, a rotating base 2, a first connecting component, a second connecting component, a first driving device 4, a material guiding channel 5, a push rod 6 and a second driving device 7.

The machine base 1 is used for supporting a slewing bearing 3, and the slewing bearing 3 refers to the slewing bearing 3 with a ball body and a spacer to be assembled. The foundation 1 may be provided as a frame structure formed by profile welding.

The first driving device 4 is connected with the rotating seat 2 and is used for driving the rotating seat 2 to rotate.

The guide channel 5 is arranged on the machine base 1, and the guide channel 5 is arranged opposite to the mounting hole of the slewing bearing 3. The preset gap is reserved between the material guide channel 5 and the outer wall of the slewing bearing 3, and the preset gap is as small as possible so as to ensure that the ball body and the spacer bush can smoothly enter the mounting hole from the material guide channel 5. The mounting holes are provided on the outer wall of the outer ring 302, and the mounting holes communicate with the raceway 303 of the slewing bearing 3. The side wall of the material guide channel 5 is provided with a material inlet for at least one of the ball body and the spacer to enter. Optionally, the feed port includes a first feed hole 32 into which the ball enters and a second feed hole 33 into which the spacer enters, and as shown in fig. 3 to 5, the distance between the first feed hole 32 and the slewing bearing 3 is smaller than the distance between the second feed hole 33 and the slewing bearing 3, so that the ball is in front of the spacer when the ball and the spacer are pushed together into the mounting hole. Alternatively, the guide channel 5 may be a tube or a housing.

The push rod 6 is movably arranged on the machine base 1 and extends into the material guide channel 5, and the push rod 6 is further arranged to extend into the mounting hole so as to push at least one of the ball body and the spacer bush in the material guide channel 5 into the mounting hole.

The second driving device 7 is connected to the push rod 6 and is used for driving the push rod 6 to move.

According to the ball assembly device provided by the embodiment of the invention, the ball and the spacer bush are placed in the guide channel, and the second driving device drives the push rod to push the ball and the spacer bush in the guide channel into the mounting hole, so that the ball and the spacer bush can be finally arranged in the raceway between the inner ring and the outer ring, the manual intervention is reduced, the automation level of ball assembly can be improved, the assembly efficiency is improved, and the labor intensity is reduced.

In some embodiments of the present invention, the stand 1 is provided with a rotatable rotating base 2, and the rotating base 2 is used for supporting a slewing bearing 3. The rotary seat 2 is provided with a first connecting component for connecting with an inner ring 301 of the slewing bearing 3, and the machine seat 1 is provided with a second connecting component for connecting with an outer ring 302 of the slewing bearing 3. Namely, the slewing bearing 3 is arranged on the rotating seat 2, the inner ring 301 is connected with the rotating seat 2 through a first connecting component, and the outer ring 302 is connected with the machine base 1 through a second connecting component.

The first driving device 4 is connected with the rotating seat 2 and is used for driving the rotating seat 2 to rotate.

In the present embodiment, the slewing bearing 3 to which the ball and the spacer are to be mounted can be supported by the slewing seat 2, the inner ring 301 of the slewing bearing 3 can be connected to the slewing seat 2 by the first connection means, and the outer ring 302 of the slewing bearing 3 can be connected to the housing 1 by the second connection means. When the ball and/or the spacer bush are arranged in the slewing bearing 3, the push rod 6 can be driven by the second driving device 7 to move along the material guide channel 5 so as to push the ball and/or the spacer bush in the material guide channel 5 into the mounting hole, and when the ball and/or the spacer bush are pushed by the push rod 6, the first driving device 4 drives the rotating seat 2 to rotate, and the rotating seat 2 drives the inner ring 301 of the slewing bearing 3 to synchronously rotate. Since the outer ring 302 of the slewing bearing 3 is connected with the machine base 1 through the second connecting component, when the inner ring 301 rotates, the outer ring 302 cannot rotate, so that the mounting hole is always aligned with the material guiding channel 5. By pushing the push rod 6 and rotating the inner ring 301, the ball and/or the spacer can smoothly enter the raceway 303 between the inner ring 301 and the outer ring 302.

By means of the arrangement, the ball body and the spacer bush can be arranged in the raceway 303 between the inner ring 301 and the outer ring 302 by pushing the rotating seat 2 through the rotating fit of the push rod 6, manual intervention is reduced, automation level of ball body assembly can be improved, assembly efficiency is improved, and labor intensity is reduced.

Referring to fig. 4 and 5, in some embodiments provided by the present invention, the ball fitting device further comprises a third driving device 8.

The push rod 6 is rotatably provided to a movable portion of the second driving device 7 so that the push rod 6 can be inclined with respect to the mounting hole. In particular, the push rod 6 is enabled to tilt relative to the axis of the mounting hole in a plane perpendicular to the axis of the slewing bearing 3. Optionally, the second driving device 7 is a linear module, and the push rod 6 is rotationally connected with a movable part of the linear module. For example, the linear module is a ball screw module or a synchronous belt module. The material guiding channel 5 is rotatably and movably matched with the machine base 1, so that the material guiding channel 5 can swing along with the push rod 6.

The third driving device 8 is disposed at the movable portion of the second driving device 7 and connected to the push rod 6, so as to drive the push rod 6 to swing.

In this embodiment, referring to fig. 3, a sphere and a spacer are placed into the guide channel 5 from the inlet of the guide channel 5 during assembly, and the sphere is placed in front of the spacer. The push rod 6 is driven to move by the second driving device 7, so that the ball body and the spacer bush in the material guide channel 5 are pushed into the mounting hole. After the ball body contacts with the inner ring 301, the third driving device 8 drives the push rod 6 to rotate, the push rod 6 inclines relative to the mounting hole, and the push rod 6 inclines and pushes one side of the spacer bush to enable the spacer bush to rotate around the ball body. As the push rod 6 pushes, the spacer rotates to the point that the axis of the spacer is tangential to the center line of the raceway 303, so that the spacer forms a correct posture. Then, the third driving device 8 drives the push rod 6 to reversely rotate, so that the push rod 6 drives the spacer bush and the ball head to a certain distance along the rollaway nest 303, and the problem that the spacer bush and the ball body form a barrier to the next ball body is solved. Further, after the ball contacts with the inner ring 301, the push rod 6 tilts, and the inner ring 301 is driven to rotate by the rotating seat 2, so that the ball and the spacer can move in the roller path more smoothly.

As shown in fig. 4 and 5, the ball fitting device may optionally further comprise a slider 34 and a push rod 6. The sliding block 34 is slidably disposed on the base 1 through a guide rail, and a moving path of the sliding block 34 forms a preset included angle with a moving path of the pushing rod 6, for example, the moving path of the sliding block 34 is perpendicular to the moving path of the pushing rod 6. The material guiding channel 5 is rotatably connected with the sliding block 34. When the push rod 6 rotates relative to the movable part of the second driving device 7, the material guide channel 5 rotates relative to the sliding block 34, and meanwhile the sliding block 34 slides along the guide rail, so that the material guide channel 5 and the machine base 1 can be rotatably and movably matched, and the material guide channel 5 is adapted to the swing of the push rod 6.

Of course, the guide path 5 is not limited to the above, and for example, a chute may be provided in the housing 1, and the chute is perpendicular to the moving path of the push rod 6. The material guide channel 5 is provided with a sliding column which is in sliding fit with the chute.

As shown in fig. 4 and 5, the third driving device 8 is optionally provided as a motor, and an output shaft of the motor drives the push rod 6 to swing through a coupling, a gear transmission, a belt transmission or a chain transmission.

In some embodiments provided by the invention, the sphere assembly device further comprises a telescopic tube 9 and a seventh driving means 10.

Wherein the telescopic tube 9 is slidably sleeved with one end of the material guiding channel 5 close to the slewing bearing 3, and the seventh driving device 10 is connected with the telescopic tube 9 and is used for driving the telescopic tube 9 to be close to or far from the slewing bearing 3.

In this embodiment, when the pivoting support 3 is taken out and put into the machine base 1, the seventh driving device 10 can drive the telescopic tube 9 to retract, so as to increase the distance between the telescopic tube 9 and the pivoting support 3, and avoid the problem of interference between the pivoting support 3 and the telescopic tube 9. When the ball and the spacer are assembled, the telescopic tube 9 can be driven to extend through the seventh driving device 10 so as to reduce the distance between the telescopic tube 9 and the slewing bearing 3, and the ball and the spacer can smoothly enter the mounting hole from the material guide channel 5 through the telescopic tube 9.

Optionally, the seventh driving means 10 is provided as a cylinder. The cylinder is arranged at the outer side of the material guiding channel 5, and the piston rod of the cylinder is connected with the telescopic pipe 9.

In some embodiments provided by the present invention, the first connection assembly comprises an abutment block 11 and a fourth driving means 12.

Wherein the number of the abutment blocks 11 is set to at least two, as shown in fig. 7 to 9 is an example in which the number of the abutment blocks 11 is set to four. The abutment blocks 11 are movably disposed on the rotating base 2, for example, the abutment blocks 11 are slidably engaged with the base 1. The abutment blocks 11 are each configured to be disposed inside the slewing bearing 3, and the abutment blocks 11 are distributed along the circumferential direction of the slewing bearing 3. I.e. the movement path of the abutment block 11 extends in the radial direction of the slewing bearing 3. The abutting blocks 11 are all used for abutting against the inner side of the slewing bearing 3, the fourth driving device 12 is arranged on the slewing seat 2 and connected with the abutting blocks 11, and the fourth driving device 12 is used for driving the abutting blocks 11 to move.

In the present embodiment, after the slewing bearing 3 is placed on the rotary seat 2, the fourth driving device 12 drives the abutting block 11 to abut against the inner ring 301 of the slewing bearing 3, so that the inner ring 301 of the slewing bearing 3 is connected to the rotary seat 2 by internal tightening.

By this arrangement, even if the inner diameter dimension of the inner ring 301 changes, the abutment block 11 can adapt to the inner diameter dimension change of the inner ring 301 and tighten the inner ring 301, thereby enabling the first connection assembly to have better adaptability and compatibility.

Referring to fig. 9, the first connection assembly may optionally further include a connection pad 13 and a first link 14. The connecting disc 13 is rotatably connected with the rotating seat 2. Alternatively, the rotation axis of the connection disc 13 is arranged coaxially with the rotation axis of the swivel base 2. The abutment blocks 11 are each connected to the connection disc 13 by respective first links 14, i.e. one end of the first link 14 is rotatably connected to the connection disc 13 and the other end is rotatably connected to the respective abutment block 11. The fourth drive 12 is connected to the coupling disc 13 and serves to drive the coupling disc in rotation.

In the present embodiment, after the slewing bearing 3 is placed on the pivot seat 2, the fourth driving device 12 drives the land 13 to rotate, and the land 13 can drive the contact block 11 to synchronously operate via the first links 14, thereby tightly pressing the inner ring 301 of the slewing bearing 3.

By the arrangement, all the abutting blocks 11 have better action synchronism and centering effect, and after the abutting blocks 11 tightly support the slewing bearing 3, the axis of the slewing bearing 3 and the rotation axis of the connecting disc 13 can be overlapped, so that a better positioning effect is formed on the slewing bearing 3.

Optionally, the fourth driving means 12 comprises a cylinder. The cylinder body of the cylinder is rotatably connected with the rotating seat 2, the piston rod of the cylinder is rotatably connected with the connecting disc 13, and the connecting point of the piston rod and the connecting disc 13 is deviated from the rotating axis of the connecting disc 13. Of course, the fourth driving device 12 may also be a motor, and an output shaft of the motor rotates with the connection disc 13, so as to drive the connection disc 13 to rotate.

Of course, the fourth driving device 12 is not limited to driving the abutment blocks 11 to move through the connecting disc 13 and the first link 14, for example, in other embodiments, the number of fourth driving devices 12 is the same as and corresponds to the number of abutment blocks 11 one by one, for example, the fourth driving device 12 may be an air cylinder, the cylinder body of which is connected with the rotating base 2, and the piston rod is connected with the corresponding abutment block 11.

In some embodiments provided by the present invention, the ball mounting device further comprises a support seat 35 and a cross rail 15,

the rotating seat 2 is matched with the supporting seat 35, and the rotating seat 2 is rotatably arranged on the supporting seat 35. The support seat 35 is provided to the housing 1 through the crisscross guide rail 15 so that the rotation seat 2 can move in a plane perpendicular to the height direction of the housing 1.

In this embodiment, after the push rod 6 extends into the mounting hole, the push rod 6 needs to incline relative to the mounting hole, so that the push rod 6 can drive the spacer bush to rotate to a correct posture, and the spacer bush and the ball move along the raceway 303, so that a problem of clamping or interference may occur between the push rod 6 and the mounting hole, by arranging the rotating seat 2 on the supporting seat 35, and the supporting seat 35 is arranged on the stand 1 through the cross guide rail 15, the rotating seat 2 can move in a plane, that is, when the push rod 6 and the hole wall of the mounting hole generate an interaction force, the slewing bearing 3 can generate an adaptive displacement, so as to reduce the problem of clamping or interference between the push rod 6 and the mounting hole.

Alternatively, the number of the crisscross rails 15 is set to four, and the four crisscross rails 15 are uniformly distributed in the circumferential direction of the rotation axis of the rotation seat 2.

In some embodiments provided by the present invention, the ball assembly device further comprises a lifting seat 16 and a lifting drive 17.

The rotating base 2 is rotatably disposed on the lifting base 16, for example, the rotating base 2 is rotatably disposed on the supporting base 35, and the supporting base 35 is mounted on the lifting base 16 through the crisscross guide rail 15. The lifting seat 16 is disposed on the base 1 in a lifting manner, for example, the lifting seat 16 is slidably connected with the base 1. Further, both sides of the lifting seat 16 are slidably connected with the stand 1. The lifting driving device 17 is installed on the base 1 and connected with the lifting seat 16, so as to drive the lifting seat 16 to move.

By the arrangement, the lifting seat 16 can be driven to lift by the lifting driving device 17, and the lifting seat 16 drives the slewing bearing 3 to lift, so that the alignment effect of the mounting hole of the slewing bearing 3 and the material guide channel 5 in the height direction of the machine base 1 is ensured.

Alternatively, the elevation driving means 17 is provided as an elevation cylinder. The cylinder body of the lifting cylinder is connected with the machine base 1, and the piston rod of the lifting cylinder is connected with the lifting seat 16. The arrangement can adjust the position height of the slewing bearing 3 so as to align the mounting seat with the material guide channel 5 in the height direction of the machine base 1. The floating buffer can be formed in the vertical direction, and as described above, when the push rod 6 interferes with and is clamped with the mounting hole, the lifting cylinder can enable the slewing bearing 3 to displace in the height direction of the machine base 1, namely when the push rod 6 interacts with the hole wall of the mounting hole, the slewing bearing 3 can generate adaptive displacement, so that the problem of clamping or interference of the push rod 6 and the mounting hole is reduced.

In some embodiments provided by the present invention, the second connection assembly includes a limit post 18, a travel seat 19, and a fifth drive 20.

Wherein the number of the movable seats 19 is two, the two movable seats 19 are movably arranged on the base 1, and the two movable seats 19 can be close to or far from each other. At least two limiting columns 18 are arranged on the movable seat 19, and the limiting columns 18 are used for propping against the outer side of the slewing bearing 3. The fifth driving device 20 is connected to the movable base 19, and is used for driving the movable base 19 to move. Further, the moving path of the moving seat 19 is perpendicular to the moving path of the push rod 6.

In the present embodiment, after the slewing bearing 3 is disposed on the rotating seat 2, the fifth driving device 20 drives the moving seats 19 to approach each other, and the limiting posts 18 on the moving seats 19 abut against the outer ring 302 of the slewing bearing 3, that is, the outer ring 302 is clamped between the limiting posts 18 of the two moving seats 19.

Referring to fig. 7, 10 and 11, the second connection assembly optionally further includes a connection seat 22 and a second link 23. The connecting seats 22 are movably arranged on the machine base 1 along the height direction of the machine base 1, and each movable seat 19 is connected with the connecting seat 22 through a corresponding second connecting rod 23.

When any one of the moving seats 19 moves, the moving seat 19 drives the connecting seat 22 to lift along the machine base 1 through the corresponding second connecting rod 23, and the connecting seat 22 drives the other second connecting rod 23 to move, so that the other second connecting rod 23 drives the other moving seat 19 to synchronously move, thereby ensuring the synchronism and the centering effect of the actions of the two moving seats 19, and further forming a better positioning effect on the slewing bearing 3.

Optionally, the moving seat 19 abuts against the outer ring 302 of the slewing bearing 3 through the limiting post 18 and positions the outer ring 302, the abutting block 11 on the rotating seat 2 abuts against the inner ring 301 of the slewing bearing 3 and positions the inner ring 301, and the rotating seat 2 is arranged on the machine base 1 through the supporting seat 35 and the cross guide rail 15, so that when the moving seat 19 positions the slewing bearing 3 through the limiting post 18, the rotating seat 2 can move along the cross guide rail 15 with the slewing bearing 3 through the supporting seat 35, and the problem that interference is generated between two positions is reduced.

Optionally, the fifth driving device 20 is provided as a cylinder, the cylinder body of which is connected to the machine base 1, and the piston rod of which is connected to the moving base 19. In the present embodiment, the cylinder drives the moving seat 19 so that the stopper post 18 of the moving seat 19 clamps the slewing bearing 3, and when the supporting seat 35 moves along the crisscross guide rail 15 with the rotating seat 2 and the slewing bearing 3, the slewing bearing 3 can compress the cylinder by the moving seat 19, so that the slewing bearing 3 can generate a certain displacement. Therefore, when the push rod 6 interacts with the mounting hole of the slewing bearing 3, the slewing bearing 3 can adaptively move, so that the interference or the clamping problem of the push rod 6 and the mounting hole is reduced.

Alternatively, the number of the fifth driving devices 20 is the same as the number of the moving seats 19, and the fifth driving devices 20 are connected in one-to-one correspondence with the moving seats 19. In this way, the clamping force to the slewing bearing 3 can be increased, and the slewing bearing 3 can be more firmly fixed.
