Description

Technical Field

[0001] This invention relates to the field of bearing processing, and more specifically, to a deep groove ball bearing inner ring feeding device that also facilitates transportation, and its method of use. Background Technology

[0002] In the large-scale production of deep groove ball bearings, the assembly line processing of the inner ring relies on efficient and precise material feeding to ensure production continuity and product consistency.

[0003] Existing material handling equipment suffers from key technical defects: most existing equipment is designed with fixed workstations and lacks integrated transportation capabilities for deep groove ball bearing inner rings. It can only complete the material handling action at preset workstations and cannot adjust the material handling position according to the production line layout, making it difficult to adapt to the switching between multiple production lines. In addition, workers must first manually transport or use additional handling tools to transfer batches of deep groove ball bearing inner rings to the equipment's storage structure before the subsequent material handling process can be started. This process not only significantly increases the labor intensity of workers but also consumes additional handling time, resulting in low production connection efficiency and making it difficult to meet the flexible and efficient material handling requirements of large-scale production.

[0004] Therefore, in order to solve the above-mentioned technical problems, this application proposes a deep groove ball bearing inner ring feeding device that also takes into account transportation and its usage method. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a deep groove ball bearing inner ring feeding device that also facilitates transportation, and its usage method.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a deep groove ball bearing inner ring feeding device that also facilitates transportation, comprising: The transport platform is equipped with four locking casters at its bottom corners, which can be used to move the transport platform to a preset workstation next to the conveyor of the processing line. A connecting platform is installed above the transport platform. An electric turntable is installed on one side of its top. Multiple limiting rods arranged in a circumferential array are installed on the top of the electric turntable. The inner ring of the deep groove ball bearing is coaxially sleeved on the outer circumference of the limiting rod. The limiting rods radially limit the inner hole of the inner ring of the deep groove ball bearing, so that multiple inner rings of the deep groove ball bearing are stacked vertically along the axial direction of the limiting rod. The lifting assembly is used to drive the support block to move up and down in the vertical direction to apply an upward thrust from the bottom of the deep groove ball bearing inner ring at the lowest point of the limiting rod, so that the multiple vertically stacked deep groove ball bearing inner rings move upward along the axis of the limiting rod. A top pushing platform is fixedly connected to the top of the lifting assembly. A circular through-slot is provided on the top pushing platform, and the inner diameter of the circular through-slot is adapted to the outer diameter of the inner ring of the deep groove ball bearing, allowing the inner ring of the deep groove ball bearing to pass through. When the inner ring of the deep groove ball bearing is pushed one by one by the support block to the top pushing platform and disengages from the limiting rod, the transverse pushing assembly installed on the top pushing platform can move in the horizontal direction to push the inner ring of the deep groove ball bearing from the top pushing platform onto the conveyor belt of the conveyor, so as to realize continuous processing and feeding in the production line.

[0007] Preferably, the lifting assembly includes a motor A fixed to the top of the connecting platform, a lead screw A connected to the power output end of the motor A, and a sleeve A threadedly connected to the outer wall of the lead screw A; the top of the connecting platform is fixedly connected to guide rails A on both the front and rear sides of the motor A for sliding sliders A, the sleeve A is fixed between the two sliders A, and the lifting of the sleeve A drives the support block to move up and down; the top push platform is fixed to the top of the guide rails A, and the head of the lead screw A is rotatably connected to the bottom of the top push platform through a bearing A.

[0008] Preferably, a circular support platform is fixedly connected to the top center of the connecting platform to support the inner ring of the lowest deep groove ball bearing sleeved on the limiting rod, so that the bottom of the inner ring of the deep groove ball bearing and the top of the connecting platform are separated, allowing the support block to extend into the lower part of the inner ring of the lowest deep groove ball bearing.

[0009] Preferably, a telescopic assembly is installed between the rod sleeve A and the support block to drive the support block to reciprocate relative to the electric turntable. When the electric turntable drives each limiting rod to rotate and move to the pushing position of the support block one by one, the telescopic assembly drives the support block away from the electric turntable to avoid interference between the limiting rod and the support block when the limiting rod rotates. After the limiting rod rotates to the correct position, the telescopic assembly drives the support block to reset to the pushing position.

[0010] Preferably, the telescopic assembly includes a connecting plate B fixed to the surface of the sleeve A, and a telescopic cylinder is installed in the middle part of the surface of the connecting plate B. The piston rod end of the telescopic cylinder is fixedly connected to the support block through a moving plate. Guide rails C for sliding sliders C are fixedly connected to both sides of the surface of the connecting plate B. The moving plate is fixed between the two sliders C.

[0011] Preferably, the top of the top push platform is equipped with baffles on both the front and rear sides of the circular through groove to restrict the movement of the inner ring of the deep groove ball bearing.

[0012] Preferably, the lateral pushing assembly includes an upper open shell fixed to the top of the top pushing platform. A lead screw B driven by a motor B is rotatably mounted inside the upper open shell, and the end of the lead screw B is rotatably connected to the inner sidewall of the upper open shell through a bearing B. A rod sleeve B is threadedly connected to the outer sidewall of the lead screw B. The top of the rod sleeve B is connected to a pushing plate that pushes the inner ring of the deep groove ball bearing onto the conveyor belt of the conveyor through a connecting plate A. A guide rail B is fixedly connected to the inner bottom wall of the upper open shell, and the bottom of the rod sleeve B is slidably connected to the guide rail B through a slider B.

[0013] Preferably, a height adjustment component is installed between the transport platform and the connecting platform to adjust the height of the connecting platform so that the height of the top push platform is adapted to the height of the conveyor belt.

[0014] Preferably, the height adjustment assembly includes an electro-hydraulic rod installed between the transport platform and the connecting platform. The top of the transport platform is fixedly connected to guide rails D for sliding of slider D on both the front and rear sides. The connecting platform is fixed between the two sliders D.

[0015] The method for using the aforementioned deep groove ball bearing inner ring feeding equipment that also facilitates transportation includes the following steps: Step 1: Place the inner ring of the deep groove ball bearing to be loaded onto the limiting rod and stack it vertically. Then, using the universal wheels with locking function at the four corners of the bottom of the transport table, move the entire set of equipment together with the inner ring of the deep groove ball bearing to be loaded to the preset station next to the conveyor of the target processing line. Lock the universal wheels to make the equipment stable and fixed, and prevent displacement during the loading process. Step 2: Based on the current height of the conveyor belt, control the extension and retraction of the electric hydraulic rod to drive the connecting platform to rise and fall smoothly along the guide rail D at the top of the transport platform via the bottom slider D until the height of the top push platform matches that of the conveyor belt, ensuring that there is no risk of collision or falling during subsequent lateral pushing. Step 3: Control the retraction of the piston rod of the telescopic cylinder to move the moving plate along the guide rail C, thereby moving the support block away from the electric turntable and reserving a non-interference space for the electric turntable to drive the limiting rod to rotate; Step 4: Start the electric turntable to rotate the circular array of limit rods, and switch the limit rods containing the inner ring of the deep groove ball bearing to the corresponding push position of the lifting assembly one by one. When the target limit rod is precisely aligned with the preset position of the support block, the electric turntable stops rotating. Step 5: Control the piston rod of the telescopic cylinder to extend in the opposite direction, drive the moving plate to reset along the guide rail C, and simultaneously drive the support block to move to the pushing position, that is, to extend into the bottom gap formed by the circular support platform and the inner ring of the lowest bearing, to complete the pushing preparation; Step Six: Control motor A to rotate forward, drive lead screw A to rotate, and the sleeve A threaded to lead screw A rises smoothly along guide rail A via slider A, driving the support block to apply upward thrust, so that the inner rings of the deep groove ball bearings stacked vertically on the limiting rod pass through the circular through groove of the top push table one by one along the axial direction. When a single inner ring of the deep groove ball bearing is pushed above the top push table and disengaged from the limiting rod, motor A stops running. Step 7: Control motor B to rotate forward, drive lead screw B to rotate, and the sleeve B threaded to lead screw B moves horizontally along guide rail B through slider B, driving push plate to move horizontally, and accurately push the inner ring of the bearing on the top push platform onto the conveyor belt of the conveyor to complete a single feeding. Step 8: Control motor B to reverse, driving the push plate to reset to the initial position. Then, motor A drives the support block to push the next deep groove ball bearing inner ring to the top push table and release it from the limiting rod. The push plate pushes it again. When a single limiting rod is finished feeding, control motor A to reverse, driving the support block to reset to the lowest point along with the rod sleeve A. At the same time, control the telescopic component to drive the support block away from the electric turntable. The electric turntable rotates to switch to the next set of limiting rods. Repeat the above actions to achieve continuous feeding.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention utilizes casters with locking function at the bottom of the transport platform, which can directly move the entire set of equipment together with the inner rings of the batch deep groove ball bearings fitted on the limiting rod to a preset work position next to the conveyor of any processing line. Locking the casters can achieve stable positioning of the equipment, and feeding can be carried out through the structure on the running platform. This directly solves the core pain points of existing equipment that cannot be adjusted due to fixed work positions and lack of integrated transportation capabilities. 2. This invention uses a baffle to prevent the inner ring of the deep groove ball bearing from falling off due to displacement during the pushing process on the top pushing platform; 3. In this invention, when the electric turntable drives each limiting rod to rotate and move one by one to the pushing position of the support block, the telescopic component drives the support block away from the electric turntable to avoid interference between the limiting rod and the support block when the limiting rod rotates. After the limiting rod rotates to the correct position, the telescopic component drives the support block to reset to the pushing position. 4. This invention uses a height adjustment component to flexibly adjust the overall height of the connecting platform, thereby accurately adapting to the height of the conveyor belt of different processing production lines. This ensures that the top pushing platform and the conveyor belt are level or have a suitable height difference, avoiding problems such as bumping or falling off the inner ring of the deep groove ball bearing during the lateral pushing process due to height mismatch.

[0019] Example 1 like Figures 1-4 as well as Figure 8 As shown, the present invention provides a deep groove ball bearing inner ring feeding device that also facilitates transportation, comprising: The transport platform 1 is equipped with four corners of its bottom with casters 2 that have locking functions. The casters 2 can be used to move the transport platform 1 to a preset workstation next to the conveyor of the processing line. The connecting platform 3 is installed above the transport platform 1. An electric turntable 4 is installed on one side of its top. Multiple limiting rods 5 arranged in a circumferential array are installed on the top of the electric turntable 4. The inner ring of the deep groove ball bearing is coaxially sleeved on the outer circumference of the limiting rod 5. The inner hole of the deep groove ball bearing is radially limited by the limiting rod 5, so that multiple inner rings of the deep groove ball bearing are stacked vertically along the axial direction of the limiting rod 5. The lifting assembly 6 is used to drive the support block 7 to move up and down in the vertical direction, so as to apply an upward thrust from the bottom of the deep groove ball bearing inner ring at the lowest point of the limiting rod 5, causing the multiple vertically stacked deep groove ball bearing inner rings to move upward along the axial direction of the limiting rod 5. The top pushing platform 8 is fixedly connected to the top of the lifting assembly 6. The top pushing platform 8 has a circular through groove 801 that runs through its upper and lower end faces. The inner diameter of the circular through groove 801 is adapted to the outer diameter of the inner ring of the deep groove ball bearing, allowing the inner ring of the deep groove ball bearing to pass through. When the inner ring of the deep groove ball bearing is pushed one by one by the support block 7 to the top pushing platform 8 and disengages from the limiting rod 5, the horizontal pushing assembly 9 installed on the top pushing platform 8 can move in the horizontal direction to push the inner ring of the deep groove ball bearing from the top pushing platform 8 to the conveyor belt of the conveyor, so as to realize continuous processing and feeding of the production line. A circular support platform 10 is fixedly connected to the top center of the connecting platform 3 to support the inner ring of the lowest deep groove ball bearing sleeved on the limiting rod 5, so that the bottom of the inner ring of the deep groove ball bearing and the top of the connecting platform 3 are separated, allowing the support block 7 to extend into the lower part of the inner ring of the lowest deep groove ball bearing.

[0020] First, using the universal wheels 2 with locking function at the bottom of the transport platform 1, the entire set of equipment, along with the batch of deep groove ball bearing inner rings fitted on the limiting rods 5, can be flexibly moved to a preset workstation next to the conveyor of any processing line. Locking the universal wheels 2 achieves stable positioning of the equipment, directly solving the core pain points of existing equipment's fixed workstations being unable to be adjusted and lacking integrated transportation capabilities. At the same time, it eliminates the step of manually moving the bearings to the equipment storage structure, significantly reducing the labor intensity of workers, reducing handling time, and improving production connection efficiency. Subsequently, the deep groove ball bearing inner rings are coaxially fitted onto the outer periphery of the limiting rods 5 arranged in a circular array on the top of the electric turntable 4. The limiting rods 5 form a radial limit on the inner hole of the bearing inner ring, ensuring that multiple bearing inner rings are stacked vertically along the axial direction without tilting. The circular support platform 10 at the top center of the connecting platform 3 supports the lowest bearing inner ring, creating a gap between its bottom and the top of the connecting platform 3, providing a stable extension space for the support block 7. After startup, the electric turntable 4 rotates, driving each set of limiting rods 5 containing bearing inner rings to switch to the corresponding position of the lifting assembly 6. Then, the lifting assembly 6 drives the support block 7 to rise vertically. The support block 7 applies an upward pushing force to the bottom of the lowest bearing inner ring through the aforementioned gap, causing a vertical row of bearing inner rings to move upward along the axis of the limiting rods 5, passing through the circular through grooves 801 on the top push platform 8 that are adapted to the outer diameter of the bearing inner rings. When a single bearing inner ring is pushed above the top push platform 8 and detached from the limiting rod 5, the lateral push assembly 9 moves horizontally, pushing the bearing inner ring onto the conveyor belt, completing a single loading. Then, the lateral push assembly 9 resets, waiting for the next bearing inner ring to be pushed above the top push platform 8 by the support block 7. After the loading of a bearing inner ring on a limiting rod 5 is completed, the lifting assembly 6 is reset, and the electric turntable 4 continues to switch to the next set of limiting rods 5, repeating the above lifting, pushing, and lateral transfer actions to achieve continuous loading.

[0021] Furthermore, baffles 13 are installed on both the front and rear sides of the circular through groove 801 at the top of the top push platform 8 to restrict the movement of the inner ring of the deep groove ball bearing. The baffles 13 prevent the inner ring of the deep groove ball bearing from falling off during the pushing process on the top push platform 8.

[0022] Example 2 like Figures 1-6As shown in the figure, this embodiment provides the specific structure of the lifting assembly 6 and the lateral pushing assembly 9 in Embodiment 1: The lifting assembly 6 includes a motor A601 fixed to the top of the connecting platform 3. The power output end of the motor A601 is connected to a lead screw A602, and a rod sleeve A603 is threaded onto the outer wall of the lead screw A602. The top of the connecting platform 3 is fixedly connected to guide rails A604 on both the front and rear sides of the motor A601, allowing the sliders A605 to slide. The rod sleeve A603 is fixed between the two sliders A605. The lifting of the rod sleeve A603 drives the support block 7 to move up and down. The top pushing platform 8 is fixed to the top of the guide rail A604. The head of the lead screw A602 is connected to the top pushing platform through a bearing A606. The bottom of the 8 is rotatably connected, and the lateral pushing assembly 9 includes an upper open shell 901 fixed to the top of the top pushing platform 8. A lead screw B902 driven by a motor B903 is rotatably installed inside the upper open shell 901, and the end of the lead screw B902 is rotatably connected to the inner side wall of the upper open shell 901 through a bearing B904. A rod sleeve B905 is threadedly connected to the outer side wall of the lead screw B902. The top of the rod sleeve B905 is connected to the pushing plate 907 that pushes the inner ring of the deep groove ball bearing to the conveyor belt of the conveyor through a connecting plate A906. A guide rail B908 is fixedly connected to the inner bottom wall of the upper open shell 901, and the bottom of the rod sleeve B905 is slidably connected to the guide rail B908 through a slider B909.

[0023] When the electric turntable 4 drives the limiting rod 5, which carries the inner ring of the deep groove ball bearing, to the corresponding position of the lifting assembly 6, the motor A601 fixed to the top of the connecting platform 3 in the lifting assembly 6 starts and controls its forward rotation. Its power output end drives the lead screw A602 to rotate (the stability of the lead screw A602's rotation is improved by the bearing A606). The bottom of the sleeve A603, which is threaded to the lead screw A602, slides upward along the guide rail A604 through the slider A605. The rotational motion of the lead screw A602 is converted into the smooth vertical upward motion of the sleeve A603, which in turn drives the support block 7 to rise. The support block 7 applies an upward thrust from the bottom of the lowest bearing inner ring, causing a vertical row of bearing inner rings to move upward along the axis of the limiting rod 5. The bearing inner rings pass through the circular through groove 801 on the top pushing platform 8, which is adapted to the outer diameter of the bearing inner ring, and disengage from the limiting rod 5 above the top pushing platform 8. Then, the horizontal pushing assembly... Motor B903 on plate 9 starts and is controlled to rotate forward, driving screw B902 to rotate (the stability of screw B902 rotation is improved by bearing B904). The bottom of the sleeve B905, which is threaded to screw B902, slides along guide rail B908 on the inner bottom wall of upper open shell 901 via slider B909, driving push plate 907 connected to the top via connecting plate A906 to move horizontally, accurately pushing the bearing inner ring onto the conveyor belt. After completing a single feeding, motor B903 is controlled to reverse, so that push plate 907 is reset, waiting for the next bearing inner ring to be pushed to the top push platform 8 by support block 7. When the bearing inner rings on one limit rod 5 are all fed, motor A601 is controlled to reverse, so that support block 7 is reset, and electric turntable 4 switches to the next set of limit rods 5, repeating the above screw drive, guide rail guidance lifting and lateral pushing actions to achieve continuous and stable feeding.

[0024] like Figure 1 and Figure 7 As shown, the present invention has a telescopic component 11 installed between the sleeve A603 and the support block 7, which is used to drive the support block 7 to reciprocate relative to the electric turntable 4. When the electric turntable 4 drives each limiting rod 5 to rotate and move to the pushing position of the support block 7 one by one, the telescopic component 11 drives the support block 7 away from the electric turntable 4 to avoid interference between the limiting rod 5 and the support block 7 when rotating. After the limiting rod 5 rotates to the position, the telescopic component 11 drives the support block 7 to reset to the pushing position.

[0025] The following is the specific structure of the telescopic assembly 11: The telescopic assembly 11 includes a connecting plate B1101 fixed to the surface of the sleeve A603, and a telescopic cylinder 1102 is installed in the middle part of the surface of the connecting plate B1101. The piston rod end of the telescopic cylinder 1102 is fixedly connected to the support block 7 through a moving plate 1103. Guide rails C1104 for sliding sliders C1105 are fixedly connected to both sides of the surface of the connecting plate B1101. The moving plate 1103 is fixed between the two sliders C1105.

[0026] When the electric turntable 4 drives each limiting rod 5 to rotate and switch to the pushing position of the support block 7 one by one, the telescopic cylinder 1102 on the connecting plate B1101 is activated. Its piston rod retracts and drives the moving plate 1103 to move. Since the moving plate 1103 is fixed between the sliders C1105 on the guide rails C1104 on both sides of the connecting plate B1101, the moving plate 1103 can move smoothly along the guide rail C1104, thereby driving the support block 7, which is fixedly connected to the moving plate 1103, away from the electric turntable 4, effectively avoiding collision and interference between the limiting rod 5 and the support block 7 during the rotation process. When the target limiting rod 5 is accurately rotated to the pushing position, the piston rod of the telescopic cylinder 1102 extends in the opposite direction, driving the moving plate 1103 to reset along the guide rail C1104, and simultaneously driving the support block 7 back to the preset pushing position, which corresponds to the gap position at the bottom of the inner ring of the deep groove ball bearing.

[0027] Furthermore, a height adjustment component 12 is installed between the transport platform 1 and the connecting platform 3 to adjust the height of the connecting platform 3. By flexibly adjusting the overall height of the connecting platform 3, it can precisely adapt to the height of the conveyor belts of different processing production lines, ensuring that the top pushing platform 8 is flush with or has a suitable height difference with the conveyor belt (the top pushing platform 8 is slightly higher than the conveyor belt). This avoids problems such as collisions or falling off of the inner ring of the deep groove ball bearing during lateral pushing due to height mismatch. The specific structure of the height adjustment component 12 is as follows: The height adjustment component 12 includes an electro-hydraulic rod 120 installed between the transport platform 1 and the connecting platform 3. 1. The top of the conveyor platform 1 is fixedly connected to the front and rear sides of the guide rails D1202 for sliding of the slider D1203. The connecting platform 3 is fixed between the two sliders D1203. It is provided with lifting power by the electric hydraulic rod 1201 installed between the conveyor platform 1 and the connecting platform 3. When it is necessary to adapt to the conveyor belt of different heights, the electric hydraulic rod 1201 is started and performs extension and retraction action, driving the connecting platform 3 to rise and fall smoothly along the guide rails D1202 through the slider D1203, so as to achieve precise adjustment of the overall height of the connecting platform 3, and then simultaneously drive the top push platform 8 to adjust to the same height as the conveyor belt or the height difference that is suitable.

[0028] This invention also provides a method for using the above-mentioned deep groove ball bearing inner ring loading equipment that also considers transportation: Step 1: Place the inner ring of the deep groove ball bearing to be loaded onto the limiting rod 5 and stack it vertically. Then, using the universal wheels 2 with locking function at the four corners of the bottom of the transport table 1, move the entire set of equipment together with the inner ring of the deep groove ball bearing to be loaded to the preset station next to the conveyor of the target processing line. Lock the universal wheels 2 to achieve stable fixation of the equipment and prevent displacement during the loading process. Step 2: Based on the current height of the conveyor belt, control the extension and retraction of the electric hydraulic rod 1201, and drive the connecting platform 3 to smoothly rise and fall along the guide rail D1202 at the top of the transport platform 1 via the bottom slider D1203 until the top pushing platform 8 is matched with the height of the conveyor belt, ensuring that there is no risk of collision or falling during subsequent lateral pushing. Step 3: Control the piston rod of the telescopic cylinder 1102 to retract, which will drive the moving plate 1103 to move along the guide rail C1104, thereby moving the support block 7 away from the electric turntable 4, leaving a space without interference for the electric turntable 4 to drive the limiting rod 5 to rotate. Step 4: Start the electric turntable 4 to drive the circular array of limiting rods 5 to rotate, and switch the limiting rods 5 loaded with the inner ring of the deep groove ball bearing to the corresponding pushing position of the lifting component 6 one by one. When the target limiting rod 5 is precisely aligned with the preset position of the support block 7, the electric turntable 4 stops rotating. Step 5: Control the piston rod of the telescopic cylinder 1102 to extend in the opposite direction, drive the moving plate 1103 to reset along the guide rail C1104, and simultaneously drive the support block 7 to move to the pushing position, that is, to extend into the bottom gap formed by the circular support platform 10 and the inner ring of the lowest bearing, and complete the pushing preparation. Step 6: Control motor A601 to rotate forward, drive lead screw A602 to rotate, and the sleeve A603 threaded to lead screw A602 rises smoothly along guide rail A604 via slider A605, driving support block 7 to apply upward thrust, so that the deep groove ball bearing inner rings stacked vertically on the limiting rod 5 pass through the circular through groove 801 of the top push platform 8 one by one along the axial direction. When a single deep groove ball bearing inner ring is pushed above the top push platform 8 and disengages from the limiting rod 5, motor A601 stops running; Step 7: Control motor B903 to rotate forward, drive lead screw B902 to rotate, and the sleeve B905 threaded to lead screw B902 moves horizontally along guide rail B908 through slider B909, driving push plate 907 to move horizontally, accurately pushing the bearing inner ring on top push platform 8 onto the conveyor belt, completing a single feeding. Step 8: Control motor B903 to reverse, driving push plate 907 to reset to the initial position. Then, motor A601 drives support block 7 to push the next deep groove ball bearing inner ring to the top push table 8 and disengage from limit rod 5. Push plate 907 pushes it again. When a single limit rod 5 is finished feeding, control motor A601 to reverse, driving support block 7 to reset to the lowest point along with rod sleeve A603. At the same time, control telescopic component 11 to drive support block 7 away from electric turntable 4. Electric turntable 4 rotates to switch to the next set of limit rods 5. Repeat the above actions to achieve continuous feeding.

[0029] The present invention provides a deep groove ball bearing inner ring loading device and its method of use that also facilitates transportation, which has the following advantages: Using the universal wheels 2 with locking function at the bottom of the transport platform 1, the entire set of equipment, together with the batch of deep groove ball bearing inner rings fitted on the limiting rod 5, can be flexibly moved to the preset work position next to the conveyor of any processing line. Locking the universal wheels 2 can achieve stable positioning of the equipment, and feeding can be carried out through the structure on the running platform 1. This directly solves the core pain points of existing equipment that cannot be adjusted at fixed work positions and does not have integrated transportation capabilities. The baffle 13 is used to prevent the inner ring of the deep groove ball bearing from falling off during the pushing process on the top push platform 8 due to displacement. When the electric turntable 4 drives each limiting rod 5 to rotate and move to the pushing position of the support block 7 one by one, the telescopic component 11 drives the support block 7 away from the electric turntable 4 to avoid interference between the limiting rod 5 and the support block 7 when rotating. After the limiting rod 5 rotates to the position, the telescopic component 11 drives the support block 7 to reset to the pushing position. By flexibly adjusting the overall height of the connecting platform 3 through the height adjustment component 12, the height of the conveyor belt of different processing production lines can be precisely adapted, so that the top pushing platform 8 and the conveyor belt are kept at the same level or with a suitable height difference, thus avoiding problems such as bumping or falling off of the inner ring of the deep groove ball bearing during the lateral pushing process due to height mismatch.
