Description

Technical Field

[0001] The invention relates to the technical field of bearing assembly, in particular to a bearing assembly device. Background Art

[0002] The bearing sealing steel cover is a key component for sealing the bearing and preventing lubricating oil from leaking. During assembly, the bearing sealing steel cover needs to be pressed into the annular gap between the inner ring and the outer ring of the bearing.

[0003] The Chinese utility model patent with publication number CN208758963U discloses an automatic capping machine for bearing assembly, which includes a capping lower die, a base and a bracket vertically connected to the upper part of the base, a laterally arranged support plate fixedly connected to the bracket, a guide sleeve vertically arranged on the support plate, a vertically arranged guide column sleeved in the guide sleeve, and a capping plate connected to the bottom of the guide column; a cylinder is also arranged on the support plate, the output shaft of the cylinder is vertically arranged downward, the end of the output shaft is fixedly connected to the capping plate, and the bottom of the capping plate is connected to the capping upper die; a stopper is provided on the base, and a notch is provided on the stopper for positioning the capping lower die; a sensor for sensing whether the capping lower die is located at the notch is also provided on the stopper at the notch. This utility model can automatically position the capping die, thereby improving the efficiency of bearing capping.

[0004] However, the above patent still adopts the traditional assembly method when assembling the sealing cylinder cover, that is, after the bearing is placed flat, the sealing steel cover is aligned with the annular gap of the bearing, and then the sealing cylinder cover is pressed into the annular gap at one end of the bearing. Then the bearing needs to be turned over and another sealing steel cover is pressed into the annular gap at the other end of the bearing in the same way.

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] See also Figure 1-8 The present invention describes the above technical solution in detail through the following embodiments:

[0045] A bearing assembly device comprises a gland platform 1 and a gland column head 2. A first feeding hole 3 penetrating the top and bottom of the gland platform 1 is provided inside the gland platform 1. Circular limiting holes 4 for limiting the sealing steel cover and communicating with the first feeding hole 3 are provided on both sides of the gland platform 1. The gland column head 2 is plugged into the circular limiting hole 4. A second feeding hole 5 for placing the sealing steel cover and communicating with the circular limiting hole 4 is provided on the top of the gland platform 1.

[0046] A support plate hole 6 connected to the first feeding hole 3 is provided on the side of the capping platform 1, and a support plate 7 for supporting the bearing is inserted into the support plate hole 6. A push-pull mechanism 8 connected to the support plate 7 is provided on the capping platform 1, and the push-pull mechanism 8 opens and closes the lower end of the first feeding hole 3 by pushing and pulling the support plate 7;

[0047] A bearing positioning assembly 9 is provided in the first feeding hole 3, and the bearing positioning assembly 9 is used to clamp and position the bearing so that the bearing on the support plate 7 is coaxial with the sealing steel cover in the circular limiting hole 4;

[0048] The outer side of the gland column 2 is connected to a punching cylinder 10, which pushes the gland column 2 so that the gland column 2 presses the sealing steel cover in the circular limiting hole 4 into the annular gap between the outer ring and the inner ring of the bearing.

[0049] Specifically, when the support plate 7 closes the lower end of the first feeding hole 3, the bearing to be capped is placed in the first feeding hole 3, and the two sealing steel covers are placed in the circular limiting holes 4 through the two second feeding holes 5 respectively. At this time, the bearing is supported on the support plate 7. Subsequently, the bearing positioning assembly 9 moves the bearing horizontally to position the bearing to a position coaxial with the sealing ring in the circular limiting hole 4. After the bearing is positioned, the stamping cylinders 10 on both sides respectively drive the two capping studs 2 to approach the bearing, so that the capping studs 2 push the sealing steel covers in the corresponding circular limiting holes 4 to move toward the annular gap between the outer ring and the inner ring of the bearing until the sealing steel covers are pressed into the annular gap, thereby realizing the synchronous assembly of the two sealing steel covers with the bearing to improve production efficiency.

[0050] In addition, after the capping is completed, the support plate 7 opens the lower end of the first loading hole 3 under the control of the push-pull mechanism 8, so that when the bearing positioning assembly 9 releases the bearing, the bearing for the capping is dropped. After the bearing drops, the push-pull mechanism 8 controls the support plate 7 to reset and closes the lower end of the first loading hole 3 to receive the next bearing to be capped.

[0051] The bearing positioning assembly 9 includes a first clamping plate 901, a first cross bar 902, a first oblique bar 903 and a first longitudinal bar 904. The first clamping plates 901 are disposed at both ends of the first feeding hole 3.

[0052] Both ends of the capping platform 1 are provided with a first transverse hole 11 connected to the first feeding hole 3, a first movable cavity 12 connected to the first transverse hole 11, and a first longitudinal hole 13 connected to the first movable cavity 12. The first longitudinal hole 13 runs through the side of the capping platform 1.

[0053] The first horizontal rod 902 is slidably plugged into the first horizontal hole 11, the first vertical rod 904 is plugged into the first vertical hole 13, and the first oblique rod 903 is movably disposed in the first movable cavity 12;

[0054] The two ends of the first oblique rod 903 are respectively hinged to the first cross rod 902 and the first longitudinal rod 904. The first oblique rod 903 is tilted relative to the first cross rod 902 and the first longitudinal rod 904. One end of the first cross rod 902 is connected to the first clamping plate 901.

[0055] The capping column head 2 is connected to the stamping cylinder 10 through a linkage plate 15, and a first sliding hole 16 is provided on the linkage plate 15 for the first longitudinal rod 904 to pass through. A first push ring 17 is provided on the first longitudinal rod 904 and located between the capping platform 1 and the linkage plate 15, and a first pull ring 18 is provided at one end of the first longitudinal rod 904 passing through the first sliding hole 16, and a first spring 19 is sleeved on the first longitudinal rod 904.

[0056] Specifically, when the punching cylinder 10 pushes the linkage plate 15 and the gland column head 2, the linkage plate 15 pushes the two first longitudinal rods 904 at both ends synchronously through the two first springs 19, and the first longitudinal rod 904 pushes the first crossbar 902 with the help of the first inclined rod 903 with adjustable angle and position, so that the two first clamping plates 901 can be synchronously close to the bearing, so as to clamp the deviated bearing and position it to a position coaxial with the sealing ring. And, after the two first clamping plates 901 clamp the bearing, the linkage plate 15 continues to push the gland column head 2 to approach the bearing, so that the gland column head 2 pushes the sealing steel cover to the bearing, and presses the sealing steel cover into the annular gap between the inner ring and the outer ring of the bearing, and in this process, the first spring 19 is further compressed. When the linkage plate 15 is driven to reset by the stamping cylinder 10, the linkage plate 15 moves away from the first push ring 17, so that the first spring 19 is stretched. During the resetting process of the linkage plate 15, when the first spring 19 is fully stretched, the linkage plate 15 pulls the first longitudinal rod 904 through the first pull ring 18 to reset the first clamping plate 901.

[0057] It should be noted that, since the height of the bearing and the sealing steel cover is limited by the support plate 7 and the wall of the circular limit hole 4 respectively, there is no strict requirement for the position of the bearing and the sealing steel cover in the axial direction of the bearing, and the two only need to remain coaxial, that is, there is no strict requirement for the width of the first feeding hole 3 and the second feeding hole 5 in the axial direction of the bearing. Compared with the bearing and the sealing steel cover, the longer and wider first feeding hole 3 and the second feeding hole 5 are conducive to the falling of the bearing and the sealing steel cover. When the longer first feeding hole 3 and the second feeding hole 5 cause the bearing and the sealing ring to deviate in the horizontal direction, resulting in the two not being coaxial, therefore, the bearing is clamped and positioned respectively by the two first clamps 901 and the two second clamps 20 that move synchronously, so as to facilitate the stable and smooth loading of the bearing and the sealing steel cover, while ensuring the coaxiality of the two when pressing the cover.

[0058] The first longitudinal hole 13 passes through both sides of the pressing platform 1, and the first inclined rods 903 on both sides are hinged with the two first longitudinal rods 904. The two first longitudinal rods 904 connected to the same first inclined rod 903 are respectively connected to the corresponding linkage plates 15 on both sides, thereby further ensuring that the two first clamping plates 901 can clamp and position the bearing.

[0059] The two ends of the circular limiting hole 4 are provided with a second clamping plate 20, a second cross bar 21, a second oblique bar 23 and a second longitudinal bar 24;

[0060] The two ends of the circular limiting hole 4 are provided with a second clamping plate 20, a second cross bar 21, a second oblique bar 23 and a second longitudinal bar 24;

[0061] Both ends of the capping platform 1 are provided with a second transverse hole 25 connecting the circular limiting hole 4 and the first active cavity 12, and a second longitudinal hole 27 connecting the first active cavity 12, and the second longitudinal hole 27 passes through the side of the capping platform 1;

[0062] The second horizontal rod 21 is slidably plugged into the second horizontal hole 25, the second vertical rod 24 is plugged into the second vertical hole 27, and the second oblique rod 23 is movably disposed in the first movable cavity 12;

[0063] The two ends of the second oblique rod 23 are respectively hinged to the second cross rod 21 and the second longitudinal rod 24. The second oblique rod 23 is tilted relative to the second cross rod 21 and the second longitudinal rod 24. One end of the second cross rod 21 is connected to the second clamping plate 20.

[0064] The linkage plate 15 is provided with a second sliding hole 28 for the second longitudinal rod 24 to pass through, a second push ring 29 is provided on the second longitudinal rod 24 and located between the pressing platform 1 and the linkage plate 15, and a second pull ring 30 is provided at one end of the second longitudinal rod 24 passing through the second sliding hole 28, and a second spring 31 is sleeved on the second longitudinal rod 24.

[0065] Since the second clamping plate 20 clamps the sealing steel cover with the help of the thrust of the compressed second spring 31, and the purpose of the second clamping plate 20 clamping the sealing ring is to calibrate the position of the sealing ring in the length direction of the second cross bar 21 rather than to clamp and fix the sealing ring, the sealing ring can be separated from the second clamping plates 20 on both sides under the push of the gland column 2, and the clamping end of the second clamping plate 20 is a smooth surface, which further facilitates the separation of the sealing ring from the second clamping plate 20.

[0066] In addition, the gland column head 2 is cylindrical, and the diameter of the gland column head 2 is larger than the inner diameter of the sealing steel cover and smaller than the outer diameter of the sealing steel cover to prevent the second clamping plate 20 from moving to the front of the gland column head 2 after detaching from the sealing steel cover.

[0067] The angle between the first oblique rod 903 and the first cross rod 902 is not less than 135°, and the first oblique rod 903 pushes the first cross rod 902. Because the first oblique rod 903 is tilted, when the first oblique rod 903 is pushed by the first longitudinal rod 904, the resistance received by the first oblique rod 903 can be decomposed into two components in the movement direction of the first longitudinal rod 904 and the movement direction of the first cross rod 902. When the angle between the first oblique rod 903 and the first cross rod 902 is greater than 135°, the component in the movement direction of the first longitudinal rod 904 is reduced, which is conducive to the first oblique rod 903 pushing the first cross rod 902. Similarly, the angle between the second oblique rod 23 and the second cross rod 21 is not less than 135°.

[0068] Further optimized in the above embodiment is that first grooves 32 for the first clamping plate 901 to enter are provided on the hole walls at both ends of the first feeding hole 3, and the depth of the first groove 32 is not less than the length of the first clamping plate 901 to avoid collision between the bearing and the first clamping plate 901 when the bearing is placed. Similarly, second grooves 26 for the second clamping plate 20 to enter are provided on the hole walls at both ends of the circular limiting hole 4, and the depth of the second groove 26 is not less than the length of the second clamping plate 20.

[0069] Further optimization of the above embodiment is that a limiting magnet 14 is embedded on the hole wall at the bottom of the circular limiting hole 4, and the limiting magnet 14 is located directly below the second loading hole 5. When the sealing steel cover falls into the circular limiting hole 4 from the second loading hole 5, the sealing steel cover is adsorbed by the limiting magnet 14 with an arc inside, thereby preventing the sealing ring from deflecting and tipping over, thereby ensuring that the sealing ring can be smoothly pressed into the annular gap between the inner ring and the outer ring of the bearing in a correct posture under the push of the gland column 2. In addition, the axial length of the limiting magnet 14 in the sealing steel cover is adapted to the axial length of the sealing steel cover, so as to further prevent the deflection of the sealing ring.

[0070] The push-pull mechanism 8 includes a transmission rod 801 and a linkage rope 802. The capping platform 1 is provided with two side holes 22 that penetrate through both sides thereof. The support plate hole 6 is located between the two side holes 22. One end of the transmission rod 801 passes through the side hole 22 and is connected to the support plate 7. The other end of the transmission rod 801 is connected to the linkage plate 15 on the same side through the linkage rope 802.

[0071] After the bearing is clamped by the two first clamping plates 901, the linkage plate 15 contacts the transmission rod 801. When the linkage plate 15 continues to push the gland column head 2 to move toward the bearing, the transmission rod 801 pushes the support plate 7 under the push of the linkage plate 15, so that the support plate 7 opens the first loading hole 3 below the bearing, and the bearing is now clamped by the two first clamping plates 901. When the linkage plate 15 is about to be reset and the two second clamping plates 20 release the bearing, the linkage rope 802 is straightened. After the linkage plate 15 is reset, the transmission rod 801 and the support plate 7 are also reset under the pull of the linkage rope 802, so that the support plate 7 can hold the bearing dropped from the first loading hole 3.

[0072] In addition, since the support plate 7 opens the lower end of the first feeding hole 3 when the bearing is clamped by the two first clamping plates 901, the bearing loses its vertical support at this time. In order to prevent the bearing from sliding downward and falling, the clamping end of the first clamping plate 901 is preferably provided with an elastic anti-slip rubber pad to increase the contact surface area and friction force of the contact surface between the first clamping plate 901 and the bearing, and the surface of the rubber pad can be provided with anti-slip texture to further prevent the bearing from slipping.

[0073] Working principle:

[0074] Put the bearing to be covered into the first loading hole 1, so that the bearing to be covered falls on the support plate 7, and then put two sealing steel covers respectively from the second loading holes 5 on both sides, so that the two sealing cylinder covers enter the circular limiting holes 4 on both sides respectively. At this time, the bearing to be covered and the two sealing steel covers are initially limited in the horizontal direction, and the axis of the bearing to be covered and the axis of the sealing steel cover are located on the same horizontal line. The stamping cylinders 10 on both sides synchronously push the linkage plate 15, so that the gland column heads 2 on both sides synchronously approach the bearing to be covered from the corresponding circular limiting holes 4. At the same time, the linkage plate 15 pushes the first longitudinal rod 901 with the help of the first spring 19 and the first push ring 17, and pushes the second longitudinal rod 24 with the help of the second spring 31 and the second push ring 29. The first longitudinal rod 901 pushes the inclined first oblique rod 903, so that the first oblique rod 903 pushes the first crossbar 902 connected to the first clamping plate 901. At the same time, the second longitudinal rod 24 pushes the inclined second oblique rod 23, so that the second oblique rod 23 pushes the second crossbar 25 connected to the second clamping plate 20, so that the bearing to be covered is clamped and positioned by the two first clamping plates 901, and the sealing steel cover is clamped and positioned by the two second clamping plates 20, so that the bearing to be covered is coaxial with the sealing steel covers on both sides. In addition, when the linkage plate 15 continues to approach the cover platform, the first spring 19 and the second spring 31 are compressed, and the cover column head 2 pushes the sealing steel cover in the circular limiting hole 4 to break away from the two second clamping plates 20, until the sealing steel cover is pressed into the annular gap on the corresponding side of the bearing to be covered under the push of the cover column head 2, so that the bearing is assembled with the two sealing steel covers at the same time.

[0075] In addition, after the bearing to be capped and the sealing steel cover are clamped and positioned, the linkage plate 15 will come into contact with the transmission rod 801 when approaching the capping platform 1, and push the support plate 7 with the help of the transmission rod 801 to open the lower end of the first feeding hole 3. When the bearing and the sealing steel cover are assembled, the linkage plate 15 is driven by the punching cylinder 10 to reset, and the linkage plate 15 pulls the first longitudinal rod 904 and the second longitudinal rod 24 through the first pull ring 18 and the second pull ring 30 to reset, so that the two first clamping plates 901 release the bearing. Since the linkage plate 15 is connected to the transmission rod 801 through a flexible linkage rope 802, the reset of the support plate 7 will lag behind the first clamping plate 901, that is, after the two first clamping plates 901 release the bearing, or the clamping force of the two first clamping plates 901 is insufficient to clamp the bearing, the lower end of the first unloading hole 5 is still in an open state, so that the assembled bearing falls from the first loading hole 3 and separates from the capping platform 1, and after the linkage plate 15 is reset, the support plate 7 is also reset under the pulling of the linkage rope 802.

[0076] It is known from common technical knowledge that the present application can be implemented by other embodiments that do not deviate from its spirit or essential features.
