[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings 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 making creative efforts shall fall within the scope of protection of the present invention.

[0042] like Figure 1-13As shown, an embodiment of the present invention provides an automated press-fitting device for the outer ring of a steering knuckle bearing of a new energy forklift, comprising a support body 2, a flow tray 1, a lifting plate 3, an upper press head 4, a lower press head 5, a hopper 6, a loading mechanism 10, and a drive mechanism. The support body 2 may include several fixedly connected plate-like and rod-like structures to form the equipment's support structure, forming mounting locations for various functional components. The support body 2 is positioned along a conveyor line 7, connecting to the preceding and following processes through the conveyor line 7 to achieve automated processing throughout the entire production process. The conveyor line 7 is used to transport workpieces, enhancing the overall level of automation. The conveyor line 7 may include two parallel, spaced-apart supports, with a wheeled or chain structure at the top end of each support to provide power to move the products or flow tray 1 on the conveyor line 7. The conveyor line 7 may also employ other conveying structures capable of achieving the conveying function. A fence 8 is provided on the outside of the support body 2 (particularly the moving structure), providing a shielding function and reducing safety hazards. Fence 8 has an operational gap for accessing and unloading materials or for maintenance. A safety grating 9 can be installed at the gap. When the safety grating 9 detects the presence of an entity within the operational gap, such as an operator reaching into the space enclosed by fence 8, the operation of silo 6 stops, meaning that silo 6 needs to remain stationary. The operation of loading mechanism 10 can also be stopped, and an alarm can be sounded to prevent accidents. Fence 8 can also be equipped with a display screen to display various operating parameters of the equipment, facilitating adjustments. Fence 8 can also be equipped with a start / stop button to control the start and stop of related devices and structures.

[0043] See also Figure 2-12 In one embodiment of the present invention, the flow tray 1 flows along with the conveyor line 7 and is used to carry processed products for circulation; the flow tray 1 can be a rectangular plate-like structure, which includes at least a flat bottom surface, the size of which is larger than the size between the two support frames of the conveyor line 7, so that it can flow smoothly on the conveyor line 7. The flow tray 1 is provided with a placement position for accommodating the steering knuckle, and the placement position can be a groove-type structure that matches the steering knuckle, or a clamping assembly can be provided for fixing the steering knuckle located thereon to ensure the stability of the steering knuckle during the entire production process. When the steering knuckle is located in the placement position on the flow tray 1, the two bearing holes of the steering knuckle are located at the upper and lower ends respectively; and a lower pressure hole is provided at the bottom end of the corresponding placement position of the flow tray 1, so as to facilitate the rise of the lower pressure head 5 to complete the press-fitting of the bearing outer ring at the lower end. The posture of the steering knuckle on the flow tray 1 is as follows. Figure 1 shown.

[0044] See also Figure 2-12In one embodiment of the present invention, the lifting plate 3 is arranged between the two brackets of the conveyor line 7, and the size of the lifting plate 3 is smaller than the size between the two brackets. The lifting plate 3 is connected to the first linear drive component 11; the first linear drive component 11 is used to drive the lifting plate 3 to rise or fall. Under normal conditions, the lifting plate 3 is lower than the height of the top of the conveyor line 7 and does not affect the flow of the transfer pallet. When the flow pallet 1 flows to the top of the lifting plate 3, the lifting plate 3 lifts the flow pallet 1 so that the flow pallet 1 is separated from the conveyor line 7 for subsequent pressing operations. A plurality of top blocks are provided on the top surface of the lifting plate 3. The top blocks can be cylindrical and are respectively provided at the edge positions of the lifting plate 3. The stability of the lifting process of the flow pallet 1 is ensured by providing the top blocks.

[0045] See also Figure 2-12 In one embodiment of the present invention, the outer diameter of the upper ram 4 matches the inner diameter of the bearing outer ring. During use, the bearing outer ring is placed onto the upper ram 4 via the loading mechanism 10. The upper ram 4 then presses downward, pressing the bearing outer ring into the bearing hole of the steering knuckle. Specifically, the upper ram 4 can have an interference fit with the inner wall of the bearing outer ring, meaning that the outer diameter of the upper ram 4 is slightly larger than the inner diameter of the bearing outer ring. This ensures that the loading mechanism maintains stability after the bearing outer ring is placed onto the upper ram 4. The second linear drive assembly 12 can be mounted on the support body 2 and is used to drive the upper ram 4 in vertical linear motion. Specifically, the movable end of the second linear drive assembly 12 is connected to the upper ram 4, and a pressing rod can be provided between the two for connection. Similarly, the outer diameter of the lower ram 5 matches the inner diameter of the bearing outer ring and is connected to the third linear drive assembly 14; the third linear drive assembly 14 is used to drive the lower ram 5 in vertical linear motion. The lifting plate 3 is provided with corresponding notches or through holes to serve as an action space for the pressing head 5 .

[0046] See also Figure 2-12In one embodiment of the present invention, the hopper 6 is located on the side of the conveyor line 7 and is used to store bearing outer rings to be assembled. Specifically, as an example, the hopper 6 includes a base plate and retaining rods fixed to the base plate. The base plate can be circular and horizontally arranged. Multiple or multiple groups of retaining rods are vertically arranged and arranged along the circumference of the base plate to retain multiple bearing outer rings that form a vertical column when stacked. The stacked bearing outer rings are stacked with their axes vertical. Multiple groups of retaining rods can be provided, each group containing only one retaining rod. In this case, the bearing outer rings are sleeved around the retaining rods. Each group of retaining rods can also contain at least three retaining rods. The inscribed circles of the retaining rods in the same group match or are slightly larger than the outer diameter of the bearing outer rings, thereby forming a space between the multiple retaining rods in the same group to accommodate the stacked bearing outer ring columns. The number of retaining rods in each group should not be too large, as this increases the difficulty of unloading the materials and the difficulty of grasping by the robot arm. Preferably, the number of retaining rods is three or four. Furthermore, a power assembly may be provided at the bottom of the silo 6 to drive intermittent rotation of the silo 6. This allows the base plate to rotate continuously, facilitating material discharge and adjusting the position of the material close to the loading mechanism 10, thereby facilitating the loading of the material by the loading mechanism 10. The specific structure of the power assembly is not limited, as long as it can drive the intermittent rotation of the base plate. For example, it can be driven by a servo motor, which is controlled by a PLC control system to control the angle of each rotation of the base plate. Other intermittent rotation structures, such as cam structures and grooved wheel mechanisms, may also be used.

[0047] See also Figure 2-12 In one embodiment of the present invention, the loading mechanism 10 is used to grab the outer ring of the bearing of the hopper 6 and place it on the upper and lower press heads 4 and 5, respectively. The loading mechanism 10 can be a commercially available manipulator (robot). As an example, the loading mechanism 10 includes a fifth linear drive assembly, a sixth linear drive assembly, a movable base 15, and a clamping jaw 13. The fifth and sixth linear drive assemblies are arranged in an intersecting manner and are respectively used to drive the movable base 15 to move linearly in the horizontal and vertical directions. The clamping jaw 13 is arranged on the movable base 15 to clamp the outer ring of the bearing. Specifically, the fifth linear drive assembly can be arranged on the support body 2 and connected to the sixth linear drive assembly via a slide, thereby enabling the sixth linear drive assembly to move horizontally or vertically. The sixth linear drive assembly is used to drive the movable base 15 to move longitudinally or horizontally. The fifth and sixth linear drive assemblies provide the movable base 15 with freedom of movement in both the horizontal and vertical directions. Specifically, the fifth linear drive assembly and the sixth linear drive assembly can be a ball screw structure, or a slide rail and slide seat structure, and are powered by a cylinder.

[0048] See also Figure 2-12 In one embodiment of the present invention, the two clamping jaws 13 are mounted on a rotating base, and the movable base 15 is provided with a rotation drive assembly for driving the rotating base. The rotation drive assembly can be a motor, a rotary cylinder, or other power source. The rotation drive assembly can be used to drive the rotating base. Combined with the two opposing clamping jaws 13, after gripping one bearing outer ring, the clamping jaws 13 can be flipped over to grip another bearing outer ring. The two bearing outer rings can then be transferred to the upper and lower press heads 4 and 5, respectively, thereby reducing the cycle time and improving production efficiency. The clamping jaws 13 can be driven by a cylinder or motor to grip the outer wall of the bearing outer ring. The two jaws of the clamping jaw 13 can slide with the rotating base, and a drive mechanism is provided to drive the two jaws of the same clamping jaw 13 toward or away from each other to achieve clamping. Alternatively, one end of the jaw can be hinged to the rotating base, allowing clamping to be achieved through the angle between the two jaws.

[0049] See also Figure 2-12 In one embodiment of the present invention, a locating shaft is provided on the upper press head 4 and / or the lower press head 5. The size of the locating shaft is smaller than the size of the upper press head 4 and the lower press head 5 (the inner diameter of the bearing outer ring) and matches the hole position between the two bearing holes of the steering knuckle to be processed. When the upper press head 4 or the lower press head 5 with the bearing outer ring approaches the steering knuckle, the locating shaft can first enter the bearing hole and the hole position, achieving secondary positioning and playing a stabilizing role in the press-fitting process. The size of the locating shaft needs to be adapted to the distance between the two bearing holes. If the locating shaft is provided on only one of the upper press head 4 or the lower press head 5, its size can be slightly larger. If the locating shaft is provided on both the upper press head 4 and the lower press head 5, the length of the locating shaft is appropriately shortened.

[0050] See also Figure 2-12 In one embodiment of the present invention, the pressing head 5 can be fixedly mounted on a pressing rod. The size of the pressing rod is larger than the inner diameter of the outer ring of the bearing. The pressing rod is connected to the third linear drive assembly 14. Furthermore, an insert block 17 is provided on the side of the pressing rod. The insert block 17 is connected to the fourth linear drive assembly 16 and can move closer to or further away from the pressing rod under the drive of the fourth linear drive assembly 16. During use, when the pressing rod drives the pressing head 5 to rise to a set position, the insert block 17 is driven by the fourth linear drive assembly 16 to approach the side of the pressing rod and abut against the side of the pressing rod, thereby ensuring the stability of the pressing rod and the pressing head 5.

[0051] See also Figure 2-12In one embodiment of the present invention, the drive mechanism includes various linear drive components, rotational drive components, and the like. The specific structures of the first linear drive component 11, the second linear drive component 12, the third linear drive component 14, the fourth linear drive component 16, the fifth linear drive component, and the sixth linear drive component can be selected according to actual conditions. As an example, the linear drive components can all be cylinder structures.

[0052] Working principle of the present invention:

[0053] The working process of this equipment can be carried out under the control of a control system (such as a PLC control system). The automatic pressing process is as follows:

[0054] Initially, the lifting plate 3 is in a low position, and the pressing head 5 is in a low position, that is, lower than the height of the conveyor line 7. Under the action of the fifth and sixth linear drive components, the movable seat 15 moves to the position where the bearing outer ring is placed in the hopper 6, that is, the position of the bearing outer ring column stacked in the limiting rod. The clamping jaw 13 grabs the bearing outer ring at the top and rises to disengage from the limiting rod. The rotating seat then rotates 180° to ensure that one end of the two bearing outer rings is facing outward to meet the press-fitting requirements. The upper empty clamping jaw 13 moves downward, and the movable seat 15 then moves downward, grabs another bearing outer ring through the second clamping jaw 13, and rises to disengage from the limiting rod. The above is the process of the feeding mechanism 10 grabbing the bearing outer ring. After grabbing, the movable seat 15 moves to the press position, that is, the position of the upper press head 4 and the lower press head 5. At the same time, the lower press head 5 rises above the top surface of the lifting plate 3, and the movable seat 15 moves down to place the lower bearing outer ring on the lower press head 5. Then it moves up to place the bearing outer ring on the upper press head 4. After the bearing outer ring is placed, the clamping jaws 13 open and then leave the press area to carry out the next bearing outer ring grabbing action. After the bearing outer ring is placed on the lower press head 5, the lower press head 5 moves down back to the low position.

[0055] When the flow tray 1 with the steering knuckle flows along the conveyor line 7 to the top of the lifting plate 3, the lifting plate 3 rises and lifts the flow tray 1 off the conveyor line 7. During this process, a positioning blocking structure 18 can be set (such as a vertically set telescopic rod. When blocking is required, the telescopic rod is higher than the conveyor line 7, and it can be released after it is retracted and lowered from the conveyor line 7. It can be driven by a cylinder). When the flow tray 1 flows along the conveyor line 7 to this position, it is blocked and released after press-fitting so that it can continue to flow downward. Then, the lower pressure head 5 rises to a high position. During this process, the positioning shaft on the lower pressure head 5 is inserted into the hole between the two bearing holes of the steering knuckle to achieve secondary precision positioning. Then, the insert 17 extends and abuts the lower pressure rod to ensure that the lower pressure head 5 is stable and does not fall. The upper pressure head 4 descends until it enters the bearing hole. At this time, the lower pressure head 5 slowly moves downward. At the same time, the flow tray 1 drives the steering knuckle product on it to move downward together, so that the upper and lower bearing outer rings are simultaneously press-fitted into the bearing hole of the steering knuckle. After press-fitting, the upper press head 4 rises back to its original position, the lower press head 5 and the lifting plate 3 fall back to their original position, and the transfer tray 1 falls to the conveyor line 7 to continue to flow. The above process is the press-fitting process.

[0056] When the robot grasps the bearing outer ring, a sensor can be installed on the gripper 13 to detect the presence of the bearing and the orientation of the outer ring component to avoid press-fitting errors. The process of grasping the bearing outer ring has a cycle time of 8 seconds and is performed simultaneously with press-fitting. The robot moves to the press position and places the bearing outer ring on the lower and upper press heads 5 and 4, a cycle time of 8 seconds. Similarly, sensors can be installed on the sides of the press heads to detect the presence of the bearing outer ring. If not, an alarm will be issued to indicate an error or the machine will be temporarily shut down. When the transfer tray 1 is in place, it stops and is lifted off the conveyor line 7. The RFID information is read to confirm product-related information. This cycle time is 4 seconds. During this process, a sensor can be installed on the side to detect the presence of the workpiece on the tray. The lower press head 5 is raised, and the process cycle is limited to 4 seconds by the action of the insert 17. The cycle time for the upper and lower press heads 4 and 5 to press the bearing outer ring into the bearing hole is 7 seconds. After press-fitting, the insert 17 is reset, the lower pressure head 5 is reset, and the flow tray 1 falls. The process cycle is 4 seconds. Specifically, the outer ring of the bearing is automatically press-fitted using the present application scheme, with a press-fit cycle of 30 seconds per piece. A pallet presence detection sensor can be installed at the position of the conveyor line 7 corresponding to the lifting plate 3. Two sensors can be arranged diagonally opposite each other to detect the presence of the flow tray 1 at the press position. The above-mentioned sensors can be photoelectric sensors, proximity sensors, optical sensors, or other types of sensors, such as infrared sensors.

[0057] The present application is provided with a feeding mechanism 10 that can be used to automatically grasp the outer rings of the bearings and transfer them to the upper pressing head 4 and the lower pressing head 5. The two pressing heads cooperate to automatically press the two outer rings of the bearings into the bearing hole of the steering knuckle simultaneously, realizing a completely automatic press-fit of the steering knuckle bearing, high production assembly efficiency and stable assembly quality. The feeding structure includes two clamping jaws 13 and is provided with a rotating seat. After grasping the first outer ring of the bearing, it rotates 180 degrees and then grasps the second outer ring of the bearing, ensuring that the outer rings pressed into the bearing hole meet the requirements.
