Description

Technical Field

[0001] The invention relates to the technical field of bearing assembly ball installation, in particular to a double-row angular contact ball bearing assembly ball installation mold and a ball installation method. Background Art

[0002] Double-row angular contact ball bearings are rolling bearings that can withstand both radial and axial loads. Compared to single-row angular contact ball bearings, double-row angular contact ball bearings have two ball rows, which can provide greater load-bearing capacity and higher rigidity. Their design enables the bearings to withstand both axial and radial forces while maintaining high operating accuracy and stability.

[0003] However, double-row angular contact ball bearings are structurally different from traditional angular contact ball bearings. Due to the larger center distance between the upper and lower grooves of the new structure, that is, the distance between the upper and lower steel balls is larger, this may cause the following problems in the assembly process of double-row angular contact ball bearings:

[0004] (1) When installing the upper side groove steel balls, the upper side steel balls are easy to leak into the lower side groove, which makes it difficult to assemble the balls, greatly increases the difficulty of assembly, and seriously affects the assembly efficiency of workers; if the upper side steel balls accidentally leak into the lower side groove, there will be more balls in the lower side groove, which may cause overload in certain areas during assembly, and the bearing raceway or steel ball surface may be easily squeezed, resulting in early damage to the bearing;

[0005] (2) After the steel balls on the upper and lower sides are assembled, it is usually necessary to use a copper needle to move the steel balls so that the circumference of the steel balls is dispersed to prevent loosening. However, when using a copper needle to move the double-row angular contact ball bearing, it is difficult to ensure that each steel ball is accurately located in its corresponding groove, resulting in the steel balls being concentrated in certain positions, affecting the stability of the overall structure. Especially when there are many steel balls, using a copper needle to move the steel balls may cause the steel balls to collide with each other, especially when there is not enough space or under the action of unbalanced forces, the steel balls may slide from one groove to another, which can easily cause loosening and affect the working performance of the bearing. In addition, the entire assembly process requires more time and higher skills, and requires a high level of experience from the operator.

[0006] Therefore, it is necessary to invent a double row angular contact ball bearing assembly ball setting die and a ball setting method. Summary of the Invention

[0016] The ball loading method of the double-row angular contact ball bearing assembly ball-loading mold mentioned above includes S1-S4;

[0017] S1. Fix the inner and outer rings of the bearing: Place the outer ring of the bearing on the assembly base, insert the C-shaped protrusion of the fitting plate into the outer ring of the bearing, then place the inner ring of the bearing on the assembly base, clamp the inner ring of the bearing on the inner side of the C-shaped protrusion of the fitting plate, and make the outer diameter of the inner ring of the bearing stick to the inner diameter surface of the rib of the outer ring of the bearing;

[0018] S2. Filling the groove steel balls: Place a certain number of bearing lower side groove steel balls on the C-shaped protrusion of the fitting plate between the outer diameter of the bearing inner ring and the inner diameter of the bearing outer ring rib. Then tighten the screw in the threaded seat upwards, slide the clamp to loosen the long rod, lower the long rod to drive the ball spacer ring downward to contact the upper surface of the bearing lower side groove steel balls, and then fill a certain number of bearing upper side groove steel balls on the ball spacer ring;

[0019] S3. Fitting: Push the inner ring of the bearing to the center of the outer ring of the bearing so that the groove surface of the inner ring of the bearing contacts the steel ball. Then slide the long rod along the guide groove to the other end of the guide groove and drive the ball ring to rotate to the side between the outer diameter of the inner ring of the bearing and the inner diameter of the rib of the outer ring of the bearing, away from the steel ball. Then lift the long rod to drive the ball ring to a position higher than the end face of the outer ring of the bearing.

[0020] S4. Ball distribution: Tilt the ball distribution seat toward the side where the steel balls gather, so that the ball distribution tube slides and accumulates under the steel balls. Then press down and pull out the assembled assembly plate. Under the push of the first spring, the ball distribution rod extends upward from the ball distribution tube and inserts it between the steel balls. Flatten the ball distribution seat and press the push plate inward. The push plate squeezes the ball distribution clamps on both sides inward. At the same time, each ball distribution tube slides into the grooves on the inside of the ball distribution clamp in turn. At the same time, the ball distribution rod drives the steel balls to the designated position. Finally, remove the bearing upward to make the ball distribution rod disengage from between the steel balls. Take out the installed bearing and place it on the next workstation.

[0021] The beneficial effects of the present invention are as follows: after the steel balls are loaded into the lower groove of the bearing, a ball spacer is inserted above the lower groove, and then the steel balls are loaded into the upper groove of the bearing, thereby preventing the upper steel balls from leaking into the lower groove during loading, thereby preventing the bearing raceway or the steel ball surface from being squeezed and damaged, reducing the assembly difficulty, and improving the assembly efficiency of workers;

[0022] After the steel balls on the upper and lower sides are assembled, they are automatically inserted between the steel balls through the push rod device, and then the positioning device is started to drive the push rod device to move the steel balls, so that the steel balls on the upper and lower sides are dispersed circumferentially, so as to ensure that the steel balls are evenly dispersed into the corresponding grooves, effectively reducing the difficulty of ball separation, avoiding collisions between the steel balls during separation, and making the overall structure of the bearing more stable.

DETAILED DESCRIPTION

[0042] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0043] Example 1, as Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 and Figure 9 - Figure 18 As shown, the ball-setting mold for the double-row angular contact ball bearing assembly in the embodiment of the first aspect of the present invention includes a filling device and a ball-distributing device;

[0044] The loading device includes an assembly base 111, a circular groove is provided in the center of the top surface of the assembly base 111, a groove 112 is provided on one side of the assembly base 111, and a fitting assembly plate 113 is inserted and installed in the groove 112, a guide plate 122 is provided above the assembly base 111, and support shafts 121 are installed at both ends of the guide plate 122, and the support shafts 121 are fixed to the top surface of the assembly base 111. A ball washer is installed on the guide plate 122, and the ball washer includes a long rod 124, and a locking structure is installed on the upper end of the support shaft 121 on one side;

[0045] The ball distribution device includes a ball distribution seat 141, which is fixedly mounted on the bottom surface of the assembly base 111. A circular groove is provided in the center of the ball distribution seat 141, and an inner column 142 is installed in the circular groove of the ball distribution seat 141. A push rod device is slidably installed between the ball distribution seat 141 and the inner column 142. The push rod device includes a ball distribution tube 151. A hollow interlayer 143 is provided in the middle of the ball distribution seat 141, and a positioning device is installed in the hollow interlayer 143.

[0046] In the above embodiment, it should be noted that the outer ring of the bearing is first placed on the assembly base 111, and the fitting plate 113 is inserted into the outer ring of the bearing. Then, the inner ring of the bearing is placed on the assembly base 111, and the inner ring of the bearing is clamped on the inner side of the fitting plate 113, so that the outer diameter of the inner ring of the bearing is in contact with the inner diameter surface of the rib of the outer ring of the bearing. Then, a certain number of steel balls are filled into the lower groove of the bearing, and then a ball spacer is inserted above the steel balls in the lower groove, and then the steel balls in the upper groove of the bearing are filled, so as to prevent the upper steel balls from leaking into the lower groove during filling, thereby preventing the bearing raceway or the surface of the steel balls from being squeezed, thereby reducing the difficulty of assembly and improving the assembly efficiency of workers.

[0047] After the steel balls on the upper and lower sides are assembled, the inner ring of the bearing is pushed to the center of the outer ring of the bearing so that the groove diameter surface of the inner ring of the bearing contacts the steel ball. Then, the long rod 124 is slid along the guide plate 122, and the ball washer is rotated to remove the ball washer. Then, the assembled assembly plate 113 is pressed down and pulled out. At this time, the push rod device pops up and automatically inserts between the steel balls. Then, the positioning device is started to drive the push rod device to move the steel balls so that the steel balls on the upper and lower sides are dispersed circumferentially, so as to ensure that the steel balls are evenly dispersed in the corresponding grooves, effectively reducing the difficulty of ball separation, avoiding collision between the steel balls during ball separation, and making the overall structure of the bearing more stable.

[0048] The locking structure is used to lock the long rod 124, which plays the role of fixing the ball pad; the width of the gap between the ball distribution seat 141 and the inner column 142 is equal to the diameter of the ball distribution tube 151, and the guide plate 122 has a C-shaped structure.

[0049] Example 2, as Figure 1 、 Figure 2 、 Figure 4 、 Figure 9 and Figure 10 As shown, the double-row angular contact ball bearing assembly mold includes embodiment 1. In addition, a C-shaped protrusion is provided on the top surface of the assembly plate 113, and the C-shaped protrusion of the assembly plate 113 is ejected from the annular groove of the assembly base 111. The ball pad includes a ball pad ring 125, and the ball pad ring 125 is provided below the guide plate 122. The guide plate 122 is provided with a guide groove 123. The long rod 124 is slidably installed in the guide groove 123. A limiting block 126 is installed on the long rod 124. The lower end of the long rod 124 is fixedly connected to one end of the ball pad ring 125.

[0050] In the above embodiment, it should be noted that the outer diameter of the C-shaped protrusion on the top surface of the fitting plate 113 is smaller than the inner diameter of the bearing outer ring, and the inner diameter of the C-shaped protrusion on the top surface of the fitting plate 113 is larger than the outer diameter of the bearing inner ring. The outer ring of the bearing is placed on the assembly base 111, and the C-shaped protrusion of the fitting plate 113 is inserted into the outer ring of the bearing. Then, the inner ring of the bearing is placed on the assembly base 111, and the inner ring of the bearing is clamped on the inner side of the C-shaped protrusion of the fitting plate 113, so that the outer diameter of the inner ring of the bearing is attached to the inner diameter surface of the rib of the outer ring of the bearing, so as to achieve the effect of fixing the inner and outer rings of the bearing and facilitating the filling of steel balls.

[0051] By filling a certain number of bearing lower side channel steel balls into the C-shaped protrusion of the fitting plate 113 between the outer diameter of the bearing inner ring and the inner diameter of the bearing outer ring rib, then loosening the long rod 124, the long rod 124 is lowered to drive the ball ring 125 downward to contact the upper surface of the bearing lower side channel steel balls, and then a certain number of bearing upper side channel steel balls are filled on the ball ring 125 to prevent the upper side steel balls from leaking into the lower side channel during filling; after the bearing inner ring and the bearing outer ring are fitted together, by sliding the long rod 124 along the guide groove 123 to the other end of the guide groove 123, and driving the ball ring 125 to rotate to the side between the outer diameter of the bearing inner ring and the inner diameter of the bearing outer ring rib away from the steel balls, then lifting the long rod 124 to remove the ball ring 125;

[0052] The limit block 126 has the function of limiting the downward movement distance of the long rod 124. When the long rod 124 drives the ball ring 125 downward, the limit block 126 continues to approach the guide plate 122 until it is stuck above the guide plate 122. The limit block 126 prevents the long rod 124 from driving the ball ring 125 to over-insert into the bearing, thereby preventing the ball ring 125 from damaging the steel ball.

[0053] Example 3, as Figure 1 - Figure 3 and Figure 9 、 Figure 11 、 Figure 13 、 Figure 15 、 Figure 17 As shown, the double-row angular contact ball bearing assembly ball mold includes embodiment 1. In addition, the locking structure includes a positioning seat 131, which is fixedly installed on the support shaft 121 on one side. A slot 132 is provided at the upper end of the positioning seat 131, and the upper end of the long rod 124 extends upward through the slot 132. A sliding clamp 134 is slidably installed in the slot 132. The locking structure includes a threaded seat 133, which is provided above one end of the slot 132. The threaded seat 133 is installed on the top surface of the positioning seat 131, and a thread is provided on the side of the sliding clamp 134 close to the threaded seat 133. The inner wall of the slot 132 below the threaded seat 133 is also provided with a thread, and a screw 135 is installed in the threaded seat 133.

[0054] In the above embodiment, it should be noted that the sliding clamp 134 is made of elastic rubber material. By screwing the screw 135 in the threaded seat 133 upward, the sliding clamp 134 can slide freely to unlock the long rod 124. By screwing the screw 135 in the threaded seat 133 downward, the lower end of the screw 135 presses the sliding clamp 134 downward to push the sliding clamp 134 to clamp and fix the long rod 124.

[0055] Example 4, as Figure 4 - Figure 8 、 Figure 17 and Figure 18 As shown, the double-row angular contact ball bearing assembly ball mold includes embodiment 1. In addition, the ejector device includes a ball dividing rod 152, which is inserted and installed in the ball dividing tube 151. A limiting protrusion is provided at the lower end of the ball dividing rod 152. A first spring 153 is installed in the ball dividing tube 151. The upper end of the first spring 153 contacts the lower end of the ball dividing rod 152. The positioning device includes a rotating rod 161, which is installed in the hollow interlayer 143 on one side of the ball dividing seat 141. Two ball dividing clamp rings 162 are rotatably installed on the rotating rod 161. The ball dividing clamp ring 162 is close to the inner column. A groove is provided on one side of 142, and a torsion spring is installed at the rotating connection between the ball dividing clamp ring 162 and the rotating rod 161. The positioning device includes a push plate 171, which is provided on the outside of the ball dividing clamp ring 162. The push plate 171 is inserted and installed on both sides of the ball dividing seat 141. The inner walls of the hollow interlayer 143 on the upper and lower sides are provided with slides 144, and the upper and lower sides of the push plate 171 are provided with slides 172. The slide 172 is slidably installed in the slide 144. A second spring 173 is installed in the slide 144. The second spring 173 is provided on the side of the slide 172 close to the inner column 142.

[0056] In the above embodiment, it should be noted that the ball-distributing rod 152 is made of a flexible plastic material, which causes less wear on the steel balls and the inner wall of the channel. When the assembled assembly plate 113 is inserted into the withdrawal groove 112, the upper end of the ball-distributing rod 152 abuts against the bottom of the assembled assembly plate 113. When the assembled assembly plate 113 is withdrawn, the ball-distributing rod 152 extends upward from the ball-distributing tube 151 under the push of the first spring 153 and is inserted between the steel balls.

[0057] The torsion spring installed at the rotational connection between the ball-dividing clamping ring 162 and the rotating rod 161 always provides an outward expansion force for the ball-dividing clamping ring 162. Under the drive of the torsion spring, the outer side of the ball-dividing clamping ring 162 presses against the inner side of the push plate 171. The number of grooves on the inner side of the ball-dividing clamping ring 162 is the same as the number of assembled ball-dividing tubes 151. The number of assembled ball-dividing tubes 151 is the same as the number of steel balls loaded in a single layer.

[0058] By pressing the push plate 171, the push plate 171 drives the slide 172 to slide and squeeze the second spring 173. The push plate 171 squeezes the ball dividing clamping rings 162 on both sides to gather inward. At the same time, each ball dividing tube 151 slides into the grooves on the inner side of the ball dividing clamping ring 162 in turn. At the same time, the ball dividing rod 152 drives the steel balls to move to the specified position, so as to achieve the effect of evenly distributing the steel balls to the corresponding channels; release the push plate 171, the second spring 173 pushes the slide 172 to drive the push plate 171 to reset, and the torsion spring drives the ball dividing clamping ring 162 to reset outward and expand.

[0059] The ball loading method of the double-row angular contact ball bearing assembly ball-loading mold of the present invention is as follows:

[0060] S1. Fix the inner and outer rings of the bearing: Place the outer ring of the bearing on the assembly base 111, insert the C-shaped protrusion of the fitting plate 113 into the outer ring of the bearing. Then place the inner ring of the bearing on the assembly base 111, clamp the inner ring of the bearing on the inner side of the C-shaped protrusion of the fitting plate 113, and make the outer diameter of the inner ring of the bearing be in contact with the inner diameter surface of the rib of the outer ring of the bearing.

[0061] S2. Loading the groove steel balls: Place a certain number of the bearing lower groove steel balls on the C-shaped protrusion of the fitting plate 113 between the outer diameter of the bearing inner ring and the inner diameter of the bearing outer ring rib. Then, tighten the screw 135 in the threaded seat 133 upward, and the sliding clamp 134 releases the long rod 124. The long rod 124 is lowered to drive the ball spacer ring 125 downward to contact the upper surface of the bearing lower groove steel balls. Then, load a certain number of the bearing upper groove steel balls on the ball spacer ring 125.

[0062] S3. Fitting: Push the inner ring of the bearing to the center of the outer ring of the bearing so that the groove surface of the inner ring of the bearing contacts the steel ball. Then slide the long rod 124 along the guide groove 123 to the other end of the guide groove 123 and drive the ball ring 125 to rotate to the side between the outer diameter of the inner ring of the bearing and the inner diameter of the rib of the outer ring of the bearing, away from the steel ball. Then lift the long rod 124 to drive the ball ring 125 to be higher than the end surface of the outer ring of the bearing. Slide the long rod 124 again into the notch 132 of the positioning seat 131. Tighten the screw 135 downward to squeeze the sliding clamp 134 and clamp the long rod 124.

[0063] S4. Ball distribution: Tilt the ball distribution seat 141 toward the side where the steel balls gather, so that the ball distribution tube 151 slides and accumulates under the steel balls. Then press down and pull out the assembled assembly plate 113. Under the push of the first spring 153, the ball distribution rod 152 extends upward from the ball distribution tube 151 and is inserted between the steel balls. Flatten the ball distribution seat 141 and press the push plate 171 inward. The push plate 171 squeezes the ball distribution clamping rings 162 on both sides to gather inward. At the same time, each ball distribution tube 151 slides into the grooves on the inside of the ball distribution clamping ring 162 in turn. At the same time, the ball distribution rod 152 drives the steel balls to move to the designated position. Finally, remove the bearing upward so that the ball distribution rod 152 is out of between the steel balls. Take out the assembled bearing and place it on the next workstation.
