Description

Technical Field

[0001] This invention relates to the field of parts conveying technology, and in particular to a parts conveying device and an automated bearing production line. Background Technology

[0002] As a fundamental component in mechanical equipment, the machining accuracy of bearings directly affects the performance and lifespan of the machine tool. The production process of bearing rings typically involves multiple steps, including turning, heat treatment, and grinding, such as face grinding, external cylindrical grinding, internal cylindrical grinding, and ultra-precision grinding. To improve production efficiency, modern bearing manufacturers employ automated production lines. Automatic conveyor systems physically connect consecutive machine tools. Existing conveyor systems often use chain-plate or belt conveyor lines. After the bearing is processed in the previous step, it slides onto the conveyor line via a slide rail and moves with the conveyor belt to the loading port of the next step. There, it is stopped by a blocking mechanism and then pushed laterally into the machine tool fixture by a cylinder for further processing.

[0003] However, in practical applications of automated bearing production, the aforementioned methods for conveying and feeding still have limitations in terms of workpiece positioning stability. Specifically, existing chain conveyor lines typically operate continuously without stopping. When a bearing is stopped at the pusher station by the blocking mechanism, relative sliding friction inevitably occurs between its bottom surface and the continuously moving conveyor chain. Under the continuous action of this dynamic friction and torque, the freely placed bearing is prone to slight circumferential deflection or attitude drift in the horizontal plane, making it difficult for the bearing end face to maintain an ideal vertical correspondence with the pusher mechanism. This uncertainty in the waiting posture increases the risk of alignment error during the pusher insertion process, thus potentially affecting the final machining accuracy.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0005] This invention provides a parts conveying device and an automated bearing production line to solve the technical problem in the prior art where the workpiece positioning posture is easily affected by the dynamic friction of continuous conveying, resulting in centering errors during the material pushing and mold insertion process.

[0006] This invention adopts the following technical solution: a parts conveying device and an automated bearing production line. It includes a conveying assembly, an auxiliary bearing assembly, a lifting assembly, and a cleaning assembly. The conveying assembly includes a frame and a first chain conveyor and a second chain conveyor arranged side-by-side on the frame, with a clearance between them. The auxiliary bearing assembly is located above one end of the first and second chain conveyors and includes a vertically sliding bearing plate. A front blocking block with a detection sensor is embedded on one side of the bearing plate. The lifting assembly is located below the frame, and its output end passes through the clearance and connects to the bearing plate, driving the bearing plate to move up and down between a bearing station and a pushing station, so that the bearing may detach from or contact the conveyor surface. The conveying assembly also includes a pushing cylinder and a V-shaped pusher for pushing the bearing located at the pushing station. The cleaning assembly is connected to the side of the auxiliary bearing assembly and moves up and down synchronously with it. The cleaning assembly is configured to clean the detection sensor on the front blocking block through blowing and scraping actions during the lifting process.

[0007] Furthermore, the conveying assembly also includes a transition slide disposed on one side of the frame, with a discharge port on one end of the transition slide. The discharge trajectory of the discharge port falls in the middle of the first chain conveyor and the second chain conveyor. A first guide rail and a second guide rail are respectively disposed on the outer sides of the first chain conveyor and the second chain conveyor.

[0008] Furthermore, the auxiliary bearing assembly also includes two sets of side frames symmetrically arranged directly above the middle of one end of the first chain conveyor and the second chain conveyor. The side frames are fixed by brackets to the side of the first chain conveyor and the second chain conveyor that are far apart from each other. A bearing plate slides vertically between the two side frames. The feed end of the bearing plate is provided with a guide ramp. The width of the guide ramp is much smaller than the diameter of the bearing, so that the bearing conveyed by the conveyor can slide into the bearing plate through the guide ramp.

[0009] Furthermore, the lifting assembly also includes a fixed frame, a lifting cylinder, a base plate, and a lifting support plate. The fixed frame is fixed below the frame, the lifting cylinder is mounted on the fixed frame and its output end is connected to the base plate, and a guide rod that moves downward through the fixed frame is fixed on the bottom surface of the base plate. The lifting support plate is T-shaped, with its vertical end passing through the clearance gap and its horizontal end positioned above the first chain conveyor and the second chain conveyor and connected to the bottom surface of the support plate.

[0010] Furthermore, the cleaning assembly includes a mounting cover, a rack, bearing seats, and an external fixing tube. The mounting cover is symmetrically arranged on the side of the side frame. The rack is vertically fixed inside the mounting cover. Two sets of bearing seats are symmetrically fixed on the side of the support plate and rise and fall synchronously with the support plate. The external fixing tube is fixed on the side of the two bearing seats that are close to each other.

[0011] Furthermore, the cleaning assembly also includes an inner vent pipe, a pipe connector, and a gear. The inner vent pipe is rotatably inserted into the outer fixed pipe. The surface of the inner vent pipe has a waist-shaped airflow groove along a straight direction. In the initial state, the airflow groove faces downward. The pipe connector is located at one end of the inner vent pipe for connecting to an external air supply device. The gear is fixedly sleeved on one end of the inner vent pipe that protrudes from the outer fixed pipe and meshes with the rack.

[0012] Furthermore, the upper surface of the external fixed tube is connected to an inclined air passage, and the air outlet of the inclined air passage is set towards the detection sensor on the front block, which is used to blow away solid particles and adhering oil layer on the sensor surface. In the initial lifting state, the air passage groove of the inner air passage is misaligned and not connected with the inclined air passage.

[0013] Furthermore, the cleaning assembly also includes a clamping rod and two sets of fixing clips. The clamping rod is fixed to one end of the inner vent tube, protruding from the outer fixing tube and rotating synchronously with it. The fixing clips are fixed to the surface of the bearing seat. When the gear rolls on the rack and passes over the rack, causing the inner vent tube to rotate, the airflow groove is aligned and connected with the inclined airway. The clamping rod is engaged in the fixing clips to maintain the connection.

[0014] Furthermore, the cleaning assembly also includes a rubber scraper and two sets of protective covers. The rubber scraper is fixed between the lower surfaces of the two sets of bearing seats and located below the outer fixed tube. It is configured to physically scrape the surface of the detection sensor after the blowing action. The protective covers are fixed to the side of the side frame and are used to shield and protect the gear.

[0015] Furthermore, it includes a parts conveying device, which is connected between a first processing machine tool and a second processing machine tool. The second processing machine tool has a feed trough plate at its entrance. A mounting frame is mounted above the conveying assembly, and the pusher cylinder is fixed on the mounting frame. When the bearing plate moves up to its position so that its upper surface is flush with one end of the side frame, the bearing plate connects with the feed trough plate, and the pusher cylinder drives the V-shaped pusher head to push the bearing into the feed trough plate.

[0016] The above-mentioned at least one technical solution adopted in this invention can achieve the following beneficial effects: A parts conveying device and an automated bearing production line are disclosed. By setting a clearance gap between two sets of chain conveyors in the conveying component, and coordinating the lifting component and the auxiliary bearing component, the lifting output end drives the bearing plate to rise and fall through the clearance gap. This allows the bearing to actively detach from the continuously running conveyor surface when it reaches the pushing station, thereby eliminating the interference of dynamic friction at the bottom on the workpiece posture. This achieves the bearing's suspended static positioning without friction interference, improving the alignment accuracy of subsequent pushing into the mold. At the same time, by setting a pushing cylinder in conjunction with a V-shaped pusher, the V-shaped contact surface is used to perform micro-alignment of the bearing and disperse contact stress, effectively avoiding workpiece damage caused by rigid impact. In addition, by setting a cleaning component connected to the side of the auxiliary bearing component and rising and falling synchronously with it, the mechanical linkage automatically performs blowing and scraping actions on the detection sensor on the front stop block during the lifting process, effectively removing the attached oil layer and solid particles on the sensor surface, thereby improving the overall stability of the parts conveying and loading process.

[0019] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0020] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] Example 1: Reference Figures 1 to 8 As shown, the present invention provides a parts conveying device and an automated bearing production line, which mainly comprises a conveying component 3, an auxiliary bearing component 4, a lifting component 5, and a cleaning component 6.

[0022] The conveying assembly 3 serves as the basic transmission unit, comprising a frame 32 that stably supports the ground. A first chain conveyor 33 and a second chain conveyor 34 are arranged side-by-side on top of the frame 32. These two sets of chain conveyors operate synchronously, with a predetermined clearance between them in the width direction. This clearance provides space for subsequent lifting operations. To prevent the bearings from deviating during transport, a first guide rail 35 and a second guide rail 36 are fixedly installed on the outside of the first chain conveyor 33 and the second chain conveyor 34. The spacing between the guide rails can be finely adjusted according to the bearing diameter.

[0023] In order to connect with the previous process, the conveying assembly 3 also includes a transition slide 31 located at the feed end on one side of the frame 32. The transition slide 31 extends in a curved shape, and a discharge port 311 is opened on the side of its end. The guide trajectory of the discharge port 311 is designed so that the bearing sliding down the slide can land in the middle position of the first chain conveyor 33 and the second chain conveyor 34, that is, straddling the clearance gap.

[0024] like Figures 6-10 As shown, an auxiliary bearing component 4 and a lifting component 5 are provided at the end of the conveying component 3 (i.e., at the material pushing station); The auxiliary support assembly 4 includes two sets of side frames 41, which are fixed to the outer surfaces of the first chain conveyor 33 and the second chain conveyor 34 respectively by brackets, and are positioned directly above the end of the conveying process. A vertical sliding channel is formed between the two sets of side frames 41, within which a support plate 42 is slidably installed, capable of sliding up and down relative to the side frames 41. A guide ramp 421 is machined at the feed end of the support plate 42, i.e., the end facing the bearing conveying direction. The width of the guide ramp 421 is designed to be smaller than the diameter of the bearing. When the chain conveyor transports the bearing to the end, the bearing slides along the guide ramp 421 and climbs to the upper surface of the bearing plate 42 under the action of friction. A front blocking block 312 is installed on the side of the bearing plate 42 away from the feed end. The front blocking block 312 is fixed to the side of the second chain conveyor 34 by the mounting rod 310. The front blocking block 312 not only serves to physically stop the bearing, but also integrates a detection sensor (such as a photoelectric sensor or proximity switch) on its side to detect whether the bearing is in place.

[0025] The lifting assembly 5 is located below the chain conveyor and includes a fixed frame 51 fixed on the frame 32. A vertically upward lifting cylinder 52 is installed on the fixed frame 51. The piston rod of the lifting cylinder 52 is connected to a base plate 53. The bottom surface of the base plate 53 is provided with multiple guide rods 531. The guide rods 531 pass downward through the fixed frame 51 to ensure the stability of the lifting process. A T-shaped lifting support plate 54 is connected above the base plate 53. The vertical part of the lifting support plate 54 passes through the clearance between the first chain conveyor 33 and the second chain conveyor 34. The horizontal end of its top is fixedly connected to the bottom surface of the upper support plate 42.

[0026] During operation, the lifting cylinder 52 drives the lifting support plate 54 to move upward, thereby causing the bearing plate 42 and the bearing located on it to switch from the bearing position (i.e., the low position, close to the surface of the conveyor chain) to the pushing position (i.e., the high position, detached from the conveyor chain).

[0027] like Figures 6-8 As shown, in response to the problem of heavy oil contamination in the grinding environment, this device is designed with a cleaning component 6, which uses the mechanical energy of the lifting and lowering of the support plate 42 to achieve automatic cleaning.

[0028] The cleaning component 6 includes a mounting cover 61, a rack 62, bearing seats 63, and a cleaning pipeline structure. The mounting cover 61 is symmetrically fixed on both sides of the stationary side frame 41. The rack 62 is vertically fixed inside the mounting cover 61. The two sets of bearing seats 63 are symmetrically fixed on the sides of the liftable support plate 42 and move synchronously with the support plate 42. Between the two sets of bearing seats 63 that are close to each other, an external fixed tube 64 is horizontally fixed.

[0029] An internal vent pipe 66 is rotatably inserted inside the external fixed tube 64. One end of the internal vent pipe 66 extends and is connected to a pipe connector 67 for connecting to external compressed air. Both ends of the internal vent pipe 66 are fitted with gears 68, which mesh with a stationary rack 62. In addition, a rubber scraper 65 is fixed on the side of the support plate 42, which is located below the external fixed tube 64. The rubber scraper 65 is preferably made of oil-resistant polyurethane, and its position is exactly in front of the detection sensor on the front stop block 312.

[0030] It should be noted that, to ensure the operational safety and anti-contamination capability of the transmission mechanism, the cleaning component 6 is also equipped with two sets of protective covers 610. The protective covers 610 are bolted to the side of the side frame 41 and are semi-enclosed shells, enclosing the gear 68 and its meshing area with the rack 62. These protective covers 610 effectively prevent external grinding fluid splashes and oil mist from directly adhering to the gear teeth of the gear 68, while also preventing accidental contact by operators or foreign objects from being drawn into the rotating gear 68, thus ensuring stable operation of the device under harsh working conditions.

[0031] This embodiment focuses on explaining the air path control logic of the cleaning component 6. The surface of the inner air pipe 66 has an waist-shaped air passage groove along the axial direction. In the initial state (when the support plate 42 is in the low position), the air passage groove faces downward. The upper surface of the outer fixed pipe 64 is connected to the inclined air passage 641. The air outlet of the inclined air passage 641 is obliquely aligned with the sensing surface of the detection sensor on the front block 312. In the initial lifting state, the waist-shaped passage groove of the inner air pipe 66 and the inclined air passage 641 on the outer fixed pipe 64 are misaligned, the air path is blocked, and no air is blown at this time.

[0032] When the lifting assembly 5 operates, causing the support plate 42 and bearing seat 63 to move upward, the gear 68 rolls upward along the stationary rack 62. The gear 68 drives the inner vent pipe 66 to rotate. When the gear 68 passes the stroke of the rack 62, the inner vent pipe 66 has rotated exactly 180 degrees. At this time, the waist-shaped groove on the inner vent pipe 66 rotates upward, aligning and communicating with the inclined air passage 641 on the outer fixed pipe 64. Compressed air is ejected through the inclined air passage 641, forcefully blowing away solid particles and adhering oil layers on the sensor surface. To maintain this communication state, i.e., to prevent the gear 68 from rotating back after disengaging from the rack 62, the cleaning assembly 6 is also equipped with a locking mechanism. This locking mechanism includes a locking rod 69 fixed to the inner vent pipe 66 and moving with it, and a corresponding fixing clamp 611 fixed on the bearing seat 63.

[0033] When the rotation is complete (i.e., the inner vent tube 66 has rotated exactly 180 degrees), the locking rod 69 engages with the fixing clamp 611, locking the inner vent tube 66 at the angle where the air passage is open. As the assembly continues to move upward, the rubber scraper 65 located below the outer fixing tube 64 follows closely and sweeps across the sensor surface. This forms a cleaning sequence in which large particles and oil layers are first removed by strong air blowing, and then the rubber scraper physically removes the residual oil film, effectively avoiding direct scraping damage to the sensor.

[0034] It should be noted that, in order to achieve orderly loading of workpieces, a baffle mechanism (not shown in the figure) is installed at the end of the transition slide 31 and near the discharge port 311. This baffle mechanism mainly consists of a baffle cylinder and a stop block, with the baffle cylinder controlled by the system controller. During operation, the baffle mechanism controls the timing of the bearing's descent through its telescopic movement, ensuring that the bearings fall onto the two-chain conveyor in single, staged steps through the discharge port 311. This effectively prevents adjacent bearings from colliding during transport due to insufficient spacing, and also prevents subsequent bearings from accidentally entering and causing mechanical interference when the auxiliary bearing assembly 4 is lifting, thereby ensuring the stability of the entire line's conveying rhythm.

[0035] Example 2: like Figures 1 to 3 and Figure 5 As shown in the figure, this embodiment elaborates on the operating logic of the bearing automated production line system based on the above-mentioned parts conveying device. The production line mainly consists of an upstream first processing machine tool 1, a downstream second processing machine tool 2, and a parts conveying device located between the two. The parts conveying device connects the first processing machine tool 1 and the second processing machine tool 2 to realize automatic flow between processes. The inlet of the second processing machine tool 2 is specially equipped with a feed chute 21, which serves as the docking interface between the internal and external conveying of the machine tool.

[0036] The conveying assembly 3 is mounted on a mounting frame 37, and a horizontally positioned pushing cylinder 38 is fixed on the mounting frame 37. The output end of the pushing cylinder 38 is equipped with a V-shaped pusher head 39, and the pushing path of the V-shaped pusher head 39 is configured to align with the feed inlet of the second processing machine tool 2. In the specific loading action, when the lifting assembly drives the bearing plate 42 to move upward and position it so that its upper surface is flush with one end of the side frame 41, the discharge end of the bearing plate 42 is seamlessly connected with the feed trough plate 21, forming a continuous planar channel. At this time, the pushing cylinder 38 is activated, driving the V-shaped pusher head 39 to extend and smoothly push the bearing located on the bearing plate 42 and which has been freed from the friction of the conveyor chain into the feed trough plate 21, thereby completing the automatic loading process to the second processing machine tool 2.

[0037] A complete automated workflow consists of the following five consecutive steps: Step S1: Gravity sliding and initial guidance. After the bearing is processed by the first processing machine tool 1, it accelerates down along the transition slide 31 under the action of gravity. When the bearing passes the discharge port 311, its movement trajectory is precisely restricted, so that it falls smoothly in the middle position between the first chain conveyor 33 and the second chain conveyor 34. At this time, the first guide guardrail 35 and the second guide guardrail 36 on both sides laterally limit the bearing to prevent it from deviating under the action of inertia, and ensure that the bearing moves forward with the conveyor chain in a horizontal posture.

[0038] Step S2: Climbing Positioning and Signal Triggering. As the chain conveyor continues to run, the bearing is transported to the auxiliary bearing assembly 4 at the end. The front end of the bearing first contacts the guide ramp 421 at the feed end of the bearing plate 42. Driven by the friction of the conveyor belt, the bearing smoothly climbs up the guide ramp 421 to the upper surface of the bearing plate 42 until it is physically stopped by the front blocking block 312. In this state, the bottom conveyor chain is still running, but the bearing is already on the bearing plate 42. There is a small amount of sliding friction between the two. The detection sensor embedded in the front blocking block 312 senses that the workpiece is in place and sends a position signal to the control system.

[0039] Step S3: Lifting and self-cleaning linkage. After receiving the signal, the control system commands the lifting cylinder 52 to move, driving the lifting support plate 54 to move upward, which in turn causes the support plate 42 and bearing to begin to be lifted vertically. During this process, the cleaning component 6 completes the blowing and sweeping actions through mechanical linkage: the bearing seat 63, which moves upward synchronously with the support plate 42, drives the gear 68 to mesh with the rack 62 stationary on the side frame 41. During the climbing process, the gear 68 rotates and drives the inner air pipe 66 to rotate 180 degrees, so that the air passage groove on its surface and the inclined air passage 641 on the outer fixed pipe 64 are aligned and connected from misalignment. Compressed air is released instantly to blow and sweep the sensor surface. Then, the rubber scraper 65 located below the air passage continues to move upward with the component and physically scrapes the sensor sensing surface to achieve deep cleaning by first blowing away impurities and then scraping away oil.

[0040] Step S4: Frictionless Flexible Feeding (Pushing Stage) When the bearing plate 42 moves to a high position, its upper surface is flush with the top of the side frame 41 and connects with the feed trough plate 21 at the entrance of the second processing machine tool 2 to form a continuous plane. At this time, the bearing is in a "suspended static state", completely separated from the continuously running conveyor chain at the bottom, eliminating the interference of dynamic friction at the bottom on the bearing posture. The pushing cylinder 38 then moves, driving the V-shaped push head 39 to extend. The V-shaped push head 39 first performs a small amount of automatic alignment on the bearing, and then pushes the bearing precisely and vertically into the feed trough plate 21 to complete the feeding.

[0041] Step S5: Reverse reset and air circuit lockout. After the material is pushed, the pushing cylinder 38 retracts, and the lifting cylinder 52 drives the bearing plate 42 to descend and reset. During the descent, the gear 68 rolls in the opposite direction along the rack 62, driving the inner air pipe 66 to rotate in the opposite direction and reset. At this time, the air passage groove and the inclined air passage 641 are misaligned again, the air circuit is automatically cut off, and the blowing stops to save energy. The bearing plate 42 returns to the low position, waiting for the arrival of the next bearing.

[0042] Working principle: After the bearing is processed by the first machining tool 1, it slides down the transition slide 31 under the action of gravity and is constrained by the trajectory of the discharge port 311, falling centrally onto the conveying assembly 3. Subsequently, the first chain conveyor 33 and the second chain conveyor 34 operate synchronously, and with the limiting effect of the guide rails on both sides, drive the bearing to be conveyed forward in a horizontal posture. When the bearing reaches the end of the conveying process, under the continuous push of the friction of the bottom conveyor chain, the bearing automatically climbs up the guide ramp 421 at the front end of the auxiliary bearing assembly 4 to the upper surface of the bearing plate 42 until it is physically stopped by the front stop block 312. At this time, the bearing is in a waiting state. The detection sensor embedded in the front stop block 312 senses the workpiece arrival signal and feeds it back to the control system, preparing to start the next stage of action.

[0043] After receiving the position signal, the control system instructs the lifting component 5 to work. The lifting cylinder 52 drives the lifting support plate 54 to move upward, which in turn lifts the support plate 42 and the bearing located on it vertically. During this process, the cleaning component 6 uses the mechanical energy of the rising support plate 42 to achieve linkage self-cleaning. The gear 68 moving upward with the support plate 42 meshes and rotates with the stationary rack 62, driving the inner vent pipe 66 to rotate 180 degrees, so that its internal air passage is aligned and connected with the inclined air passage 641 on the outer fixed pipe 64, instantly releasing compressed air to forcefully blow away the oil and particles on the sensor surface. Next, the rubber scraper 65 located below the air passage continues to rise with the component, physically scraping the sensor sensing surface, completing a deep cleaning process of first blowing away impurities and then scraping away oil, ensuring long-term reliable detection. At the same time, with the completion of the lifting action, the bearing is completely lifted and detached from the continuously running conveyor chain at the bottom, eliminating the interference of dynamic friction on the bearing's posture, and entering an ideal suspended and stationary state ready to be pushed.

[0044] When the support plate 42 moves to its highest position, its upper surface is flush with the top of the side frame 41, forming a seamless continuous planar channel with the feed chute 21 at the entrance of the second processing machine tool 2. At this time, the pusher cylinder 38 is activated, driving the V-shaped pusher head 39 to extend. The V-shaped pusher head 39 first uses the V-shaped groove to perform micro-automatic alignment of the bearing, and then pushes the bearing smoothly into the feed chute 21 in a precise vertical posture, completing the automatic feeding to the second processing machine tool 2. After the pushing is completed, each cylinder retracts, and the support plate 42 descends to its reset position. During the descent, the gear 68 rotates in the opposite direction to drive the internal air pipe 66 to reset, the air circuit is automatically cut off to save energy, and the device returns to its initial state, waiting for the arrival of the next bearing, thereby achieving efficient and high-precision automated cyclic production.
