Description

Technical Field

[0001] This application belongs to the technical field of steel ball installation, specifically relating to a steel ball pressing and embedding device. Background Technology

[0002] Bearing housings are mechanical components used to fix and support bearings. Based on their structure, bearing housings can be divided into two types: integral bearing housings (as the name suggests, they are a single, one-piece structure) and split bearing housings. Split bearing housings include a bearing housing base and a bearing housing cover located on the bearing housing base. For split bearing housings, to facilitate the installation of the bearing housing cover, steel balls are usually embedded in the end face of the bearing housing cover, and receiving holes for accommodating the steel balls are provided on the bearing housing base. The fit between the steel balls and the receiving holes positions the bearing housing cover, thus facilitating its installation.

[0003] To facilitate the installation of steel balls on the bearing housing cover, a steel ball pressing device is considered. However, because one end of the bearing housing cover has an arc shape, while the other end, where the steel ball needs to be installed, has a flat surface, the existing steel ball pressing device cannot install the steel balls on the bearing housing cover. To utilize the existing steel ball pressing device, it needs to be modified by adding a placement position that matches the arc surface of the bearing housing cover to support the bearing housing. Although the modified steel ball pressing device can install the steel balls, it cannot continuously feed them. This necessitates manual feeding of the steel balls during installation, thus affecting the installation efficiency. Utility Model Content

[0004] This application provides a steel ball pressing device to improve the efficiency of steel ball installation on the bearing housing cover.

[0005] The technical solution adopted in this application is as follows:

[0006] A steel ball pressing device, comprising:

[0007] The base has a press-fit position for placing the bearing housing cover;

[0008] A ball guide plate, located above the pressing position, is provided with a ball guide hole for the steel ball to pass through;

[0009] A ball guide channel, located above the ball guide plate;

[0010] A hopper for storing steel balls is located above the ball guide channel, and the bottom of the hopper is connected to the ball guide channel so that the steel balls inside the hopper can enter the ball guide channel.

[0011] A ball-pushing plate, located between the ball-guiding channel and the ball-guiding plate, the ball-pushing plate having a ball-pushing hole penetrating through its own thickness direction, the ball-pushing plate having a first position where the ball-pushing hole communicates with the ball-guiding channel and a second position where the ball-pushing hole communicates with the ball-guiding hole and the ball-pushing plate blocks the ball-guiding channel;

[0012] A driving member, the driving member being connected to the ball-pushing plate and used to drive the ball-pushing plate to move between a first position and a second position;

[0013] A pressing assembly that can extend into the ball guide hole to apply downward pressure to the steel ball located in the ball guide hole.

[0014] By adopting the above technical solution, when installing steel balls on the bearing housing cover using the steel ball pressing device of this application, multiple steel balls are first placed in the hopper so that the steel balls enter the ball guide channel from the bottom of the hopper, and the steel ball at the bottom of the ball guide channel enters the ball pusher hole of the ball pusher plate; then the bearing housing cover is placed in the pressing position, so that the position of the bearing housing cover where the steel balls need to be installed is aligned with the ball guide hole on the ball guide plate; then the drive unit is activated, the drive unit drives the ball pusher plate, and moves the ball pusher plate from the first position to the second position, and the steel ball in the ball pusher hole follows the ball pusher under the action of the ball pusher hole wall. The plate moves, eventually moving the ball-pushing plate to the second position. At this point, the ball-pushing hole and the ball-guiding hole are connected. The steel ball in the ball-pushing hole moves downward under the action of gravity, causing the steel ball to abut against the position on the bearing housing cover where the steel ball needs to be installed. Then, the drive unit drives the ball-pushing plate from the second position to the first position, so that the steel ball at the bottom of the ball-guiding channel enters the ball-pushing hole. Then, the pressing assembly is activated, so that the pressing assembly extends into the ball-guiding hole and applies downward pressure to the steel ball, ultimately embedding the steel ball into the bearing housing cover, thus completing the installation of the steel ball on the bearing housing cover. After installation, the pressing assembly moves in the opposite direction to achieve reset.

[0015] The steel ball pressing device in this application not only enables the installation of steel balls on the bearing housing cover, but also enables automatic feeding of steel balls to avoid the need for manual feeding, thereby improving the efficiency of installing steel balls on the bearing housing cover.

[0016] Optionally, the steel ball pressing device further includes a ball drop guide seat, which is provided with a guide hole, and the guide hole forms the ball guide channel;

[0017] And / or, the thickness H of the ball-pushing plate and the diameter D of the steel ball satisfy: D≤H<2D.

[0018] By adopting the above technical solution, the guide hole located on the guide seat forms a ball guide channel, which increases the stability of the ball guide channel and avoids the possibility of the steel ball getting stuck in the ball guide channel. This ensures the smooth installation of steel balls on the bearing housing cover, reduces the failure rate of the steel ball pressing device, and ensures the efficiency of installing steel balls on the bearing housing cover.

[0019] Because the thickness of the ball pusher plate is greater than or equal to the diameter of the steel ball but less than twice the diameter of the steel ball, when the ball pusher plate moves toward the second position under the action of the drive component, only one steel ball can be accommodated in the ball pusher hole. This ensures that there is only one steel ball in each guide ball hole. On the one hand, this ensures that the pressing assembly can apply downward pressure to the steel ball to ensure the embedding quality of the steel ball. On the other hand, it avoids the situation where excess steel balls fall off after the bearing housing cover is removed from the pressing position, thus reducing the cost of installing steel balls on the bearing housing cover.

[0020] Optionally, the base is provided with a placement seat, and the top of the placement seat is provided with a fixing pin that can pass through the through hole of the bearing seat cover. The placement seat and the fixing pin together constitute the pressing position.

[0021] By adopting the above technical solution, when placing the bearing housing cover, first align the through hole of the bearing housing cover with the fixing pin, and then lower the bearing housing cover so that the fixing pin extends into the through hole of the bearing housing cover. The fixing pin is used to position the bearing housing cover, thereby increasing the stability of the bearing housing cover in the press-fit position, ensuring the stability of the bearing housing cover during the installation of the steel balls, and further ensuring the installation quality of the steel balls.

[0022] Optionally, the placement seat is slidably connected to the base so that the placement seat has a pressing position located directly below the ball guide plate and a feeding position located on the side of the ball guide plate. The base is provided with a power member connected to the placement seat, and the power member is used to drive the placement seat to move between the feeding position and the pressing position.

[0023] By adopting the above technical solution, the bearing housing cover is placed on the placement seat, and after the fixing pin extends into the through hole of the bearing housing cover, the power unit is activated to drive the placement seat. The placement seat slides relative to the base, and the placement seat moves from the loading position to the pressing position, and finally moves the placement seat to the pressing position, so that the position on the bearing housing cover where the steel ball needs to be installed is aligned with the guide ball hole. After the steel ball is installed on the bearing housing cover, the power unit drives the placement seat from the pressing position to the loading position so that the bearing housing cover can be removed from the placement position.

[0024] When the placement seat is in the feeding position, it is located on the side of the guide plate. This allows the bearing seat cover to avoid contact with the guide plate when the bearing seat cover is placed, thus facilitating the placement of the bearing seat cover in the pressing position and further improving the efficiency of installing steel balls on the bearing seat cover.

[0025] Optionally, the fixing pin is detachably connected to the placement base;

[0026] And / or, two fixing pins are provided at intervals, and a positioning part extending into the bearing housing cover is provided between the two fixing pins.

[0027] By adopting the above technical solution, since the fixing pin is detachably connected to the placement seat, on the one hand, the fixing pin can be replaced according to the model of the bearing seat cover to increase the flexibility of the steel ball pressing device; on the other hand, worn fixing pins can be replaced to ensure the fixing effect of the fixing pin on the bearing seat cover, thereby ensuring the quality of steel ball embedding in the bearing seat cover.

[0028] Because there are two fixed pins spaced apart, the number of connection points between the pressing position and the bearing housing cover is increased, which further increases the fixing stability of the pressing position on the bearing housing cover, thereby ensuring the quality of embedding the steel ball into the bearing housing cover. Furthermore, because a positioning part extending into the bearing housing cover is provided between the two fixed pins, the positioning part and the bearing housing cover can cooperate to prevent mistaken installation, thereby avoiding misalignment of the bearing housing cover and further improving the efficiency of installing the steel ball into the bearing housing cover.

[0029] Optionally, the side of the ball-pushing plate is provided with a mounting hole communicating with the ball-pushing hole, and the ball-pushing plate is provided with a first proximity switch, the detection end of the first proximity switch extending into the mounting hole.

[0030] By adopting the above technical solution, since the detection end of the first proximity switch extends into the mounting hole, the steel ball located in the ball pushing hole can trigger the first proximity switch. When the ball pushing plate is in the first position and the first proximity switch is triggered, the first proximity switch sends a signal to the drive unit so that the drive unit can drive the ball pushing plate to move. When the ball pushing plate is in the first position and the first proximity switch is not triggered, the drive unit cannot drive the ball pushing plate to move, causing the drive unit to stop working and unable to drive the ball pushing plate, thereby reminding the staff to add steel balls to the hopper or to check the channel for conveying steel balls.

[0031] Optionally, the pressing assembly includes a punch head and an actuator, the punch head being connected to the actuator, and the actuator being used to drive the punch head to move toward or away from the guide ball hole.

[0032] By adopting the above technical solution, when the steel ball enters the guide ball hole, the actuator is activated, and the actuator drives the punch head, which then moves the punch head toward the direction close to the guide ball hole, so that the punch head extends into the guide ball hole and applies downward pressure to the steel ball located in the guide ball hole, thereby causing the steel ball to enter the interior of the bearing seat cover under the pressure of the punch head, so as to achieve the pressing and embedding of the steel ball.

[0033] Optionally, the stamping head has a stamping section that can extend into the guide ball hole, and the end of the stamping section is provided with a semi-circular groove;

[0034] And / or, the steel ball pressing device further includes a second proximity switch located on the side of the punch head, the punch head being provided with a protrusion protruding from its outer peripheral surface, the second proximity switch being used to detect whether the protrusion is in place.

[0035] By adopting the above technical solution, since the end of the stamping section is provided with a semi-circular groove, when the stamping head applies pressure to the steel ball, the steel ball can contact the inner wall of the semi-circular groove, thereby increasing the contact area between the steel ball and the stamping head. On the one hand, this increases the stability of the steel ball, and on the other hand, it reduces the pressure between the stamping head and the steel ball, so as to avoid the steel ball being easily damaged due to the large pressure. This further improves the installation efficiency and installation quality of the steel ball.

[0036] During the pressing process of the punch head embedding the steel ball, the punch head moves towards the direction of the guide ball hole, causing the protrusion to move with the punch head. When the punch head embeds the steel ball in place, the protrusion is located at the position of the second proximity switch. The second proximity switch then detects that the punch head has reached its position and sends a signal to the actuator. Under the action of the signal from the second proximity switch, the actuator moves the punch head away from the guide ball hole. This avoids the steel ball being damaged due to excessive pressure caused by the actuator continuously driving the punch head, thus ensuring the installation quality of the steel ball. At the same time, it realizes the automatic driving of the actuator to move the punch head away from the guide ball hole, thereby improving the automation level of the steel ball embedding device.

[0037] Optionally, the steel ball pressing device further includes a disturbance component located inside the hopper and a rotating component disposed in the hopper, the rotating component being connected to the disturbance component and used to drive the disturbance component to rotate.

[0038] By adopting the above technical solution, during the use of the steel ball pressing device, the rotating component is activated to drive the agitator to rotate, thereby agitating the steel balls in the hopper. This allows the steel balls to enter the guide ball channel under their own gravity, thus avoiding the situation where multiple steel balls get stuck in the hopper and cannot enter the guide ball channel, thereby ensuring the smooth discharge of materials from the hopper.

[0039] Optionally, the base includes a substrate, a first support disposed on the substrate, and a second support disposed on the substrate. The steel ball pressing device further includes a ball drop guide seat. The second support is located on the side of the first support. The pressing assembly, the ball guide plate, and the ball drop guide seat are all disposed on the first support. The hopper and the driving component are all disposed on the second support, and the hopper is located above the driving component. The hopper is connected to the ball guide channel through a conveying pipe.

[0040] By adopting the above technical solution, since the pressing assembly, guide plate, and ball drop guide seat are all located on the first support, the pressing assembly, guide plate, and ball drop guide seat are integrated together, thereby reducing the volume of the steel ball pressing device and increasing the stability of the pressing assembly, guide plate, and ball drop guide seat. Furthermore, since the hopper and drive unit are all located on the second support, the hopper and drive unit are integrated together, thereby reducing the volume of the steel ball pressing device and increasing the stability of the hopper and drive unit. Moreover, since the hopper is located above the drive unit and is connected to the ball drop guide channel through a conveying pipe, the position of the hopper is raised to increase the kinetic potential energy of the steel ball moving through the hopper to the ball drop guide channel, ensuring that the steel ball can move smoothly into the ball drop guide channel.

[0041] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0042] 1. The steel ball pressing device of this application includes a base, a guide plate, a guide channel, a hopper, a pusher plate, a drive component, and a pressing assembly. The base has a pressing position for placing the bearing housing cover. The guide plate is located above the pressing position and has guide holes for steel balls to pass through. The guide channel is located above the guide plate. The hopper is used to store steel balls and is located above the guide channel. The bottom of the hopper is connected to the guide channel so that the steel balls inside the hopper can enter the guide channel. The pusher plate is located between the guide channel and the guide plate and has push holes that extend through its own thickness. The ball pusher plate has a first position where the ball pusher hole communicates with the ball guide channel and a second position where the ball pusher hole communicates with the ball guide hole and the ball pusher plate blocks the ball guide channel. The drive member is connected to the ball pusher plate and is used to drive the ball pusher plate to move between the first position and the second position. The ball pressing assembly can extend into the ball guide hole to apply downward pressure to the steel ball located in the ball guide hole. As a result, the ball pressing device in this application not only realizes the installation of steel balls on the bearing housing cover, but also realizes automatic feeding of steel balls to avoid the need for manual feeding, thereby improving the efficiency of installing steel balls on the bearing housing cover.

[0043] 2. The ball bearing pressing device in this application also includes a ball drop guide seat. The ball drop guide seat is provided with a guide hole, which forms a ball guide channel, thereby increasing the stability of the ball guide channel and preventing the ball bearing from getting stuck in the ball guide channel. This ensures the smooth installation of the ball bearing on the bearing housing cover, reduces the failure rate of the ball bearing pressing device, and ensures the efficiency of installing the ball bearing on the bearing housing cover.

[0044] 3. The base in this application is provided with a placement seat, and the top of the placement seat is provided with a fixing pin that can pass through the through hole of the bearing housing cover. The placement seat and the fixing pin together constitute a pressing position. When placing the bearing housing cover, the through hole of the bearing housing cover is first aligned with the fixing pin, and then the bearing housing cover is lowered, so that the fixing pin extends into the through hole of the bearing housing cover. The fixing pin is used to position the bearing housing cover, thereby increasing the stability of the bearing housing cover in the pressing position, so as to ensure the stability of the bearing housing cover during the installation of the steel ball, and further ensuring the installation quality of the steel ball.

Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0066] Reference Figures 1 to 13 A steel ball pressing and embedding device is disclosed, comprising a base 1, a guide plate 2, a guide channel, a hopper 3, a pusher plate 4, a drive component 5, and a pressing and embedding assembly 6. The base 1 has a pressing and embedding position for placing a bearing seat cover 8. The guide plate 2 is located above the pressing and embedding position and has guide holes 21 for steel balls to pass through. The guide channel is located above the guide plate 2. The hopper 3 is used to store steel balls and is located above the guide channel. The bottom of the hopper 3 communicates with the guide channel so that steel balls inside the hopper 3 can enter the guide channel. In the ball guide channel, the ball pusher 4 is located between the ball guide channel and the ball guide plate 2. The ball pusher 4 is provided with a ball pusher hole 41 that extends through its own thickness direction. The ball pusher 4 has a first position where the ball pusher hole 41 communicates with the ball guide channel and a second position where the ball pusher hole 41 communicates with the ball guide hole 21 and the ball pusher 4 blocks the ball guide channel. The drive member 5 is connected to the ball pusher 4 and is used to drive the ball pusher 4 to move between the first position and the second position. The pressing assembly 6 can extend into the ball guide hole 21 to apply downward pressure to the steel ball located in the ball guide hole 21.

[0067] Understandably, the hopper 3 can hold multiple steel balls, the feed end of the ball guide channel is connected to the bottom of the hopper 3, one end face of the ball pusher plate 4 in the thickness direction contacts the ball guide plate 2, and the other end face of the ball pusher plate 4 in the thickness direction contacts the discharge end of the ball guide channel.

[0068] Specifically, when using the ball bearing pressing device of this application to install ball bearings on the bearing housing cover 8, multiple ball bearings are first placed in the hopper 3 so that the ball bearings enter the ball guide channel from the bottom of the hopper 3, and the ball bearing at the bottom of the ball guide channel enters the ball pusher hole 41 of the ball pusher plate 4; then the bearing housing cover 8 is placed in the pressing position, so that the position of the bearing housing cover 8 where the ball bearings need to be installed is aligned with the ball guide hole 21 on the ball guide plate 2; then the drive unit 5 is activated, the drive unit 5 drives the ball pusher plate 4, and causes the ball pusher plate 4 to move from the first position to the second position, and the ball bearing in the ball pusher hole 41 moves with the ball pusher plate 4 under the action of the hole wall of the ball pusher hole 41. Finally, the ball pusher plate 4 moves to the second position, at which point the ball pusher hole 41 connects with the ball guide hole 21. The steel ball in the ball pusher hole 41 moves downward under the action of gravity, causing the steel ball to abut against the position on the bearing seat cover 8 where the steel ball needs to be installed. Then, the drive unit 5 drives the ball pusher plate 4 from the second position to the first position, so that the steel ball at the bottom of the ball guide channel enters the ball pusher hole 41. Then, the pressing assembly 6 is activated, so that the pressing assembly 6 extends into the ball guide hole 21 and applies downward pressure to the steel ball, so that the steel ball is finally embedded in the bearing seat cover 8, thus completing the installation of the steel ball on the bearing seat cover 8. After the installation is completed, the pressing assembly 6 moves in the opposite direction to achieve reset.

[0069] The steel ball pressing device in this application not only enables the installation of steel balls on the bearing housing cover 8, but also enables automatic feeding of steel balls to avoid the need for manual feeding, thereby improving the efficiency of installing steel balls on the bearing housing cover 8.

[0070] It should be noted that, since the bearing housing cover 8 needs to install two steel balls, the pressing and embedding assembly 6 is arranged in two sets at intervals, the ball pusher plate 4 is arranged with two ball pusher holes 41 at intervals, and the ball guide channel is arranged in two ways. The pressing and embedding assembly 6, the ball pusher holes 41 and the ball guide channel are arranged in a one-to-one correspondence.

[0071] This application does not specifically limit the relationship between the diameters of the ball guide hole 21, the ball guide channel, and the ball push hole 41 and the diameter of the steel ball. Preferably, the diameters of the ball guide hole 21, the ball guide channel, and the ball push hole 41 are equal to 1.1 times the diameter of the steel ball to ensure that the steel ball can pass smoothly through the ball guide hole 21, the ball guide channel, or the ball push hole 41. In other embodiments, the diameters of the ball guide hole 21, the ball guide channel, and the ball push hole 41 can also be equal to the diameter of the steel ball or greater than the diameter of the steel ball but less than twice the diameter of the steel ball.

[0072] This application does not specifically limit the structure of the driving component 5; preferably, refer to... Figure 3The driving component 5 is a three-axis, three-bar cylinder, which has a push plate. A fixing plate 43, fixedly connected to the push plate, extends from the ball-pushing plate 4. The fixing plate 43 is perpendicular to the ball-pushing plate 4, thereby enabling the three-axis, three-bar cylinder to drive the ball-pushing plate 4 to move between a first position and a second position. In other embodiments, the driving component 5 can also be other cylinders, hydraulic cylinders, electric actuators, combinations of motors and transmission structures, or other structures capable of driving the ball-pushing plate 4 to move between the first and second positions.

[0073] This application does not specify the formation method of the ball guide channel; preferably, refer to... Figure 3 , Figure 4 and Figure 7 The ball pressing device also includes a ball drop guide seat 7, which is provided with a guide hole 71. The guide hole 71 forms a ball guide channel, thereby increasing the stability of the ball guide channel and preventing the ball from getting stuck in the ball guide channel. This ensures the smooth installation of the ball on the bearing housing cover 8, reduces the failure rate of the ball pressing device, and ensures the efficiency of installing the ball on the bearing housing cover 8.

[0074] This application does not specifically limit the central axis of the guide hole 71. Preferably, the central axis of the guide hole 71 extends vertically to ensure the smooth flow of the steel ball as it falls along the ball guide channel. In other embodiments, the central axis of the guide hole 71 may also be set at an angle to the vertical direction.

[0075] Furthermore, refer to Figure 7 The ball guide seat 7 is provided with a connecting groove 711 on the side facing the pressing position, which is connected to the guide hole 71, so that the operator can observe whether there are still steel balls in the ball guide channel through the connecting groove 711, so as to facilitate the operator to add steel balls to the hopper 3.

[0076] In other embodiments, the steel ball pressing device also includes a guide tube, the interior of which forms a ball guiding channel, in order to reduce the manufacturing cost of the steel ball pressing device.

[0077] This application does not specifically limit the relationship between the thickness of the ball-pushing plate 4 and the diameter of the steel ball. Preferably, the thickness H of the ball-pushing plate 4 and the diameter D of the steel ball satisfy: D≤H<2D.

[0078] If the thickness of the ball pusher plate 4 is less than the diameter of the steel ball, the steel ball in the ball pusher hole 41 may get stuck with the discharge end of the ball guide channel when the ball pusher plate 4 moves toward the second position. This will not guarantee the smooth movement of the ball pusher plate 4 and may also damage the ball guide channel.

[0079] If the thickness of the ball-pushing plate 4 is greater than twice the diameter of the steel ball, it will result in at least two steel balls being able to be accommodated in the ball-pushing hole 41 at the same time, which will lead to a waste of steel balls.

[0080] By setting the thickness of the ball pusher plate 4 to be greater than or equal to the diameter of the steel ball but less than twice the diameter of the steel ball, it is possible to ensure that when the ball pusher plate 4 moves toward the second position under the action of the drive member 5, only one steel ball can be accommodated in the ball pusher hole 41. This ensures that there is only one steel ball in each guide ball hole 21. On the one hand, it ensures that the pressing and embedding assembly 6 can apply downward pressure to the steel ball to ensure the embedding quality of the steel ball. On the other hand, it avoids the situation where excess steel balls fall off after the bearing seat cover 8 is removed from the pressing and embedding position, thus reducing the cost of installing steel balls on the bearing seat cover 8.

[0081] Preferably, the thickness of the ball-pushing plate 4 is equal to the diameter of the steel ball, so as to improve the smoothness of the movement of the ball-pushing plate 4 between the first position and the second position.

[0082] In other embodiments, the thickness of the ball-pushing plate 4 can be set to be greater than or equal to twice the diameter of the steel ball.

[0083] In a preferred embodiment, refer to Figure 4 The ball guide hole 21 passes through the ball guide plate 2 in the thickness direction. The thickness of the ball guide plate 2 is equal to the diameter of the steel ball, so that only one steel ball can be accommodated in the ball guide hole 21, thereby avoiding the waste of steel ball.

[0084] This application does not specifically limit the structure of the base 1. Preferably, the base 1 includes a base plate 11, a first support 12 disposed on the base plate 11, and a second support 13 disposed on the base plate 11. The steel ball pressing device also includes a ball drop guide seat 7. The second support 13 is located on the side of the first support 12. The pressing component 6, the ball guide plate 2, and the ball drop guide seat 7 are all disposed on the first support 12. The hopper 3 and the driving component 5 are all disposed on the second support 13.

[0085] It is understood that the first bracket 12 and the second bracket 13 are both fixedly connected to the base plate 11, the pressing assembly 6, the ball guide plate 2 and the ball drop guide seat 7 are all fixedly connected to the first bracket 12, and the hopper 3 and the drive component 5 are all fixedly connected to the second bracket 13.

[0086] Since the pressing assembly 6, the ball guide plate 2, and the ball drop guide seat 7 are all located on the first bracket 12, the pressing assembly 6, the ball guide plate 2, and the ball drop guide seat 7 are integrated together, thereby reducing the volume of the steel ball pressing device and increasing the stability of the pressing assembly 6, the ball guide plate 2, and the ball drop guide seat 7.

[0087] Since both the hopper 3 and the drive component 5 are located on the second bracket 13, the hopper 3 and the drive component 5 are integrated together, thereby reducing the volume of the steel ball pressing device and increasing the stability of the hopper 3 and the drive component 5.

[0088] This application does not specify the method of fixing the ball guide plate 2 to the first bracket 12. Preferably, refer to Figure 4 The ball guide plate 2 is fixedly connected to the first bracket 12 by bolts, which increases the stability of the ball guide plate 2 and facilitates its replacement. In other embodiments, the ball guide plate 2 can also be fixedly connected to the first bracket 12 by other methods, such as welding or screw fixing.

[0089] This application does not specifically limit the structure of the first support 12 and the second support 13. Preferably, the first support 12 is a frame structure with a C-shaped cross-section, while the second support 13 is a structure formed by stacking multiple frame structures with C-shaped cross-sections, in order to reduce the manufacturing cost of the first support 12 and the second support 13. In other embodiments, the first support 12 and the second support 13 may also have other structures.

[0090] This application does not specify the location of the hopper 3 or its connection with the ball guide channel. Preferably, refer to Figure 2 The hopper 3 is located above the drive unit 5, and the hopper 3 is connected to the ball guide channel through the conveying pipe, thereby raising the position of the hopper 3 to increase the kinetic potential energy of the steel ball moving through the hopper 3 to the ball guide channel, so as to ensure that the steel ball can move smoothly into the ball guide channel.

[0091] Understandably, the bottom of the hopper 3 is provided with a ball outlet 33, the diameter of which is larger than the diameter of the steel ball, the inner diameter of the conveying pipe is larger than the diameter of the steel ball, and one end of the conveying pipe is connected to the ball outlet 33, while the other end of the conveying pipe is connected to the ball inlet end of the ball guide channel, so as to ensure that the steel ball can enter the ball guide channel through the conveying pipe.

[0092] Furthermore, the hopper 3 is located on top of the second support 13 to further raise the position of the hopper 3, thereby further ensuring the smooth entry of steel balls into the ball guide channel.

[0093] This application does not specifically limit the structure of the hopper 3. Preferably, the hopper 3 has a circular cross-sectional shape to ensure that the hopper 3 can hold a certain number of steel balls, thereby reducing the frequency of adding steel balls to the hopper 3 and further improving the efficiency of installing steel balls on the bearing housing cover 8. In other embodiments, the hopper 3 may also have a bucket-shaped bottom to ensure the smooth entry of steel balls into the ball guide channel.

[0094] In other embodiments, the hopper 3 can be directly fixedly connected to the feed end of the ball guide channel, and the bottom of the hopper 3 is bucket-shaped.

[0095] In other embodiments, the base 1 may also be other structures.

[0096] In a preferred embodiment, refer to Figure 11 The steel ball pressing device also includes a disturbance component located inside the hopper 3 and a rotating component 32 located in the hopper 3. The rotating component 32 is connected to the disturbance component and is used to drive the disturbance component to rotate.

[0097] Specifically, during the use of the steel ball pressing device, the rotating component 32 is activated to drive the agitator to rotate, thereby agitating the steel balls in the hopper 3. This allows the steel balls to enter the ball guide channel under their own gravity, thus preventing multiple steel balls from getting stuck in the hopper 3 and being unable to enter the ball guide channel, thereby ensuring the smooth discharge of the hopper 3.

[0098] Preferably, the top of the hopper 3 is open, and the top of the hopper 3 is provided with a hopper cover 31. The end face area of ​​the hopper cover 31 is smaller than the cross-sectional area of ​​the hopper 3, so that a ball-adding port is formed between the hopper cover 31 and the top of the hopper 3, so as to facilitate the addition of steel balls to the hopper 3. The rotating part 32 is fixedly connected to the hopper cover 31 to increase the stability of the rotating part 32.

[0099] This application does not specifically limit the structure of the rotating component 32. Preferably, the rotating component 32 is a motor to reduce the production cost of the steel ball pressing device. In other embodiments, the rotating component 32 can also be a pneumatic motor or other structures capable of driving the rotating component to rotate.

[0100] This application does not specifically limit the structure of the disturbance component. Preferably, the disturbance component includes a connecting section connected to the output shaft of the rotating component 32 and a disturbance section perpendicular to the connecting section. The disturbance section is located at the bottom of the hopper 3, so as to drive the steel balls at the bottom of the hopper 3, thereby causing the steel balls at the bottom of the hopper 3 to move relative to the hopper 3, so as to ensure that the steel balls smoothly enter the conveying pipe through the ball outlet 33. In other embodiments, the disturbance component may also be other structures, such as an inclined sheet structure.

[0101] This application does not specifically limit the formation method of the intercalation site; preferably, refer to... Figure 8 The base 1 is provided with a placement seat 111, and the top of the placement seat 111 is provided with a fixing pin 112 that can pass through the through hole 81 of the bearing seat cover 8. The placement seat 111 and the fixing pin 112 together constitute a pressing position.

[0102] It should be noted that the through hole 81 of the bearing housing cover 8 mentioned above refers to the hole structure on the bearing housing cover 8 that allows bolts to pass through.

[0103] When placing the bearing housing cover 8, first align the through hole 81 of the bearing housing cover 8 with the fixing pin 112, and then lower the bearing housing cover 8 so that the fixing pin 112 extends into the through hole 81 of the bearing housing cover 8. The fixing pin 112 is used to position the bearing housing cover 8, thereby increasing the stability of the bearing housing cover 8 in the press-fit position, ensuring the stability of the bearing housing cover 8 during the installation of the steel balls, and further ensuring the installation quality of the steel balls.

[0104] Furthermore, refer to Figure 8 The placement seat 111 is slidably connected to the base 1 so that the placement seat 111 has a pressing position located directly below the ball guide plate 2 and a feeding position located on the side of the ball guide plate 2. The base 1 is provided with a power member 116 connected to the placement seat 111. The power member 116 is used to drive the placement seat 111 to move between the feeding position and the pressing position.

[0105] After placing the bearing housing cover 8 on the placement seat 111 and inserting the fixing pin 112 into the through hole 81 of the bearing housing cover 8, start the power unit 116 to drive the placement seat 111. The placement seat 111 slides relative to the base 1 and moves from the loading position to the pressing position. Finally, the placement seat 111 moves to the pressing position, and the position on the bearing housing cover 8 where the steel ball needs to be installed is aligned with the guide ball hole 21. After the steel ball is installed on the bearing housing cover 8, the power unit 116 drives the placement seat 111 from the pressing position to the loading position so that the bearing housing cover 8 can be removed from the placement position.

[0106] When the placement seat 111 is in the feeding position, it is located on the side of the guide plate 2. Therefore, when the bearing seat cover 8 is placed, the bearing seat cover 8 and the guide plate 2 can be made to avoid each other, so as to facilitate the placement of the bearing seat cover 8 in the pressing position, thereby further improving the efficiency of installing steel balls on the bearing seat cover 8.

[0107] Preferably, the feeding position is located on the side of the pressing position away from the second bracket 13, so that the feeding position and the second bracket 13 form a separation, so as to facilitate the placement of the bearing seat cover 8 in the pressing position.

[0108] The better one is to refer to Figure 8 The substrate 11 is provided with a slide rail 115, and the bottom of the placement seat 111 is provided with a slider 114 that is slidably connected to the slide rail 115, so as to guide the movement of the placement seat 111 by the cooperation of the slider 114 and the slide rail 115, thereby increasing the stability of the placement seat 111 during movement.

[0109] This application does not specifically limit the structure of the power component 116; however, preferred embodiments are described below. Figure 8 The power component 116 is a cylinder, and the piston rod of the cylinder is connected to the placement seat 111 to reduce the production cost of the steel ball pressing device and ensure the stability of the placement seat 111 during movement. In other embodiments, the power component 116 can also be a hydraulic cylinder, an electric actuator, or other structures capable of driving the placement seat 111 to move.

[0110] This application does not specify the connection method between the fixing pin 112 and the placement seat 111. Preferably, refer to... Figure 8 and Figure 10 The fixing pin 112 is detachably connected to the placement seat 111. On the one hand, the fixing pin 112 can be replaced according to the model of the bearing seat cover 8 to increase the flexibility of the steel ball pressing device. On the other hand, the worn fixing pin 112 can be replaced to ensure the fixing effect of the fixing pin 112 on the bearing seat cover 8, thereby ensuring the quality of steel ball embedding in the bearing seat cover 8.

[0111] This application does not specify the detachable connection method between the fixing pin 112 and the placement base 111. Preferably, refer to Figure 8 and Figure 10 The fixing pin 112 is connected to the placement base 111 by a threaded connection to facilitate replacement of the fixing pin 112. In other embodiments, the fixing pin 112 can also be detachably connected to the placement base 111 by a plug-in engagement.

[0112] In other embodiments, the fixing pin 112 may also be connected to the placement base 111 by welding or fastener fixation.

[0113] In a preferred embodiment, refer to Figure 8 There are two fixed pins 112 spaced apart, and a positioning part 113 that extends into the bearing housing cover 8 is provided between the two fixed pins 112.

[0114] It is understandable that a groove structure is provided on the arc-shaped surface of the bearing housing cover 8, and the positioning part 113 is located in the middle of the two fixing pins 112. The positioning part 113 can be inserted into the groove structure.

[0115] Since there are two fixed pins 112 spaced apart, the number of connection points between the pressing position and the bearing housing cover 8 is increased, thereby further increasing the fixing stability of the pressing position on the bearing housing cover 8 and ensuring the quality of embedding steel balls into the bearing housing cover 8. Furthermore, since a positioning part 113 extending into the bearing housing cover 8 is provided between the two fixed pins 112, the positioning part 113 and the bearing housing cover 8 can be used to prevent mistaken installation, thereby avoiding misalignment of the bearing housing cover 8 and further improving the efficiency of installing steel balls into the bearing housing cover 8.

[0116] This application does not impose specific limitations on the structure of the positioning part 113. Preferably, the positioning part 113 is a block structure to ensure the structural strength of the positioning part 113. In other embodiments, the positioning part 113 may also be a rod-shaped structure, etc.

[0117] In other embodiments, the press-fitting position can also be formed by a block structure provided on the substrate 11, as long as it can support and position the bearing seat cover 8.

[0118] In a preferred embodiment, refer to Figure 6 The side of the ball-pushing plate 4 is provided with a mounting hole that communicates with the ball-pushing hole 41. The ball-pushing plate 4 is provided with a first proximity switch 42, and the detection end of the first proximity switch 42 extends into the mounting hole.

[0119] Understandably, the steel ball can trigger the first proximity switch 42. When the ball pusher plate 4 is in the first position and the first proximity switch 42 is not triggered, the first proximity switch 42 cannot send a signal to the drive unit 5, causing the drive unit 5 to stop working and unable to drive the ball pusher plate 4.

[0120] Since the detection end of the first proximity switch 42 extends into the mounting hole, the steel ball located in the ball pushing hole 41 can trigger the first proximity switch 42. When the ball pushing plate 4 is in the first position and the first proximity switch 42 is triggered, the first proximity switch 42 sends a signal to the drive unit 5 so that the drive unit 5 can drive the ball pushing plate 4 to move. When the ball pushing plate 4 is in the first position and the first proximity switch 42 is not triggered, the drive unit 5 cannot drive the ball pushing plate 4 to move, so that the drive unit 5 stops working and cannot drive the ball pushing plate 4, thereby reminding the staff to add steel balls to the hopper 3 or to check the channel for conveying steel balls.

[0121] The better one is to refer to Figure 4 and Figure 5 The ball guide plate 2 is provided with a clearance groove 22 corresponding to the first proximity switch 42. The length direction of the clearance groove 22 extends along the movement direction of the ball pusher plate 4 so that the first proximity switch 42 can avoid the ball guide plate 2, thereby ensuring the smooth movement of the ball pusher plate 4.

[0122] This application does not specifically limit the structure of the embedding component 6; preferably, refer to... Figure 1 and Figure 2 The pressing assembly 6 includes a punch head 61 and an actuator 62. The punch head 61 is connected to the actuator 62, and the actuator 62 is used to drive the punch head 61 to move toward or away from the guide ball hole 21.

[0123] Specifically, after the steel ball enters the guide ball hole 21, the actuator 62 is activated, which drives the punch head 61, causing the punch head 61 to move towards the guide ball hole 21, so that the punch head 61 extends into the guide ball hole 21 and applies downward pressure to the steel ball located in the guide ball hole 21, thereby causing the steel ball to enter the interior of the bearing seat cover 8 under the pressure of the punch head 61, so as to achieve the pressing and embedding of the steel ball.

[0124] This application does not specifically limit the structure of the actuator 62. Preferably, the actuator 62 is a cylinder, with the cylinder body fixedly connected to the top of the first bracket 12, and the piston rod of the cylinder passing through the bracket and connected to the stamping head 61. In other embodiments, the actuator 62 may also be a hydraulic cylinder, an electric actuator, or other structures capable of driving the stamping head 61 to move in a direction close to or away from the guide ball hole 21.

[0125] Furthermore, refer to Figure 9 The stamping head 61 has a stamping section that can extend into the guide ball hole 21. A semi-circular groove 612 is provided at the end of the stamping section away from the actuator 62. The radius of the semi-circular groove 612 is equal to the radius of the steel ball. This allows the steel ball to contact the inner wall of the semi-circular groove 612 when the stamping head 61 applies pressure to the steel ball, thereby increasing the contact area between the steel ball and the stamping head 61. This increases the stability of the steel ball and reduces the pressure between the stamping head 61 and the steel ball, thus preventing the steel ball from being easily damaged due to excessive pressure. This further improves the installation efficiency and quality of the steel ball.

[0126] Furthermore, refer to Figures 1 to 3 The steel ball pressing device also includes a second proximity switch 121 located on the side of the punch head 61. The second proximity switch 121 is fixedly connected to the side of the first bracket 12. The punch head 61 is provided with a protrusion 611 protruding from its outer peripheral surface. The second proximity switch 121 is used to detect whether the protrusion 611 is in place.

[0127] It is understandable that the detection end of the second proximity switch 121 faces the side where the protrusion 611 is located. The second proximity switch 121 can send a signal to the actuator 62. When the protrusion 611 moves to the position of the second proximity switch 121, the second proximity switch 121 is triggered, so that the second proximity switch 121 sends a signal to the actuator 62, so that the actuator 62 drives the stamping head 61 in a direction away from the guide ball hole 21.

[0128] Specifically, during the pressing process of the punch head 61 pressing the steel ball, the punch head 61 moves towards the direction close to the guide ball hole 21, causing the protrusion 611 to move along with the punch head 61. When the punch head 61 presses the steel ball into place, the protrusion is located at the position of the second proximity switch 121. The second proximity switch 121 then detects that the punch head 61 has reached the position, and sends a signal to the actuator 62. Under the action of the signal sent by the second proximity switch 121, the actuator 62 moves the punch head 61 away from the guide ball hole 21 to avoid the steel ball being damaged due to excessive pressure caused by the actuator 62 continuously driving the punch head 61. This ensures the installation quality of the steel ball and realizes that the actuator 62 automatically drives the punch head 61 away from the guide ball hole 21, thereby improving the automation level of the steel ball pressing device.

[0129] Preferably, the protrusion 611 is an annular structure extending circumferentially along the stamping head 61.

[0130] This application does not specify the connection method between the stamping head 61 and the actuator 62. Preferably, the stamping head 61 is threaded to the piston rod of the actuator 62 to facilitate the replacement of the stamping head 61. In other embodiments, the stamping head 61 may also be connected to the actuator 62 by other fixed connection methods.

[0131] In other embodiments, the pressing component 6 may also be other structures capable of pressing steel balls.

[0132] For any parts not mentioned in this application, existing technologies may be used or referenced.

[0133] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0134] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
