Description

Technical Field

[0001] This invention belongs to the technical field of conveying devices for shock absorber production, and specifically relates to an automatic conveying device for a shock absorber production line. Background Technology

[0002] Shock absorbers are used to suppress the oscillations caused by the rebound of the spring after absorbing shock and the impact from the road surface. They are widely used in automobiles to accelerate the attenuation of vibrations in the chassis and body, thereby improving the ride smoothness of the car. When driving over uneven roads, although the shock-absorbing spring can filter out the vibrations from the road surface, the spring itself will still have reciprocating motion. Shock absorbers are used to suppress this spring bounce.

[0003] In the existing technology, during the processing of shock absorbers, it is necessary to transport the shock absorber components to the lubrication equipment via a chain conveyor or transmission belt. Then, the shock absorbers are manually moved one by one to the lubrication equipment for adding lubricating oil. However, with the development of technology, relying solely on manual lubrication can no longer meet production needs. Therefore, there is a need for an automatic conveying device that can automatically transport the shock absorber components to the lubrication equipment for adding lubricating oil and return them to the chain conveyor or transmission belt after the lubricating oil has been added. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic conveying device for a shock absorber production line that improves production efficiency.

[0005] The technical solution of the present invention is as follows:

[0006] An automatic conveying device for a shock absorber production line includes a conveyor line with two identical loading / unloading devices and a clamping and transferring device. The clamping and transferring device includes a displacement adjusting component, a clamping block mounted on the displacement adjusting component, a drive motor mounted on the clamping block, three sets of clamping jaws arranged side by side on the clamping block, and three transmission components capable of driving the drive motor. The displacement adjusting component can drive the clamping block to perform multi-directional displacement adjustment. The transmission components are mounted on the clamping block. When the drive motor is working, the drive motor drives one or more sets of clamping jaws to work through the transmission components.

[0007] Furthermore, the clamping block has three grooves on its lower side and three drive slots on its upper side. The three drive slots are respectively located between the three grooves, and the three sets of grippers are individually located in the three grooves.

[0008] Furthermore, the transmission assembly includes a lead screw connected separately to a set of grippers, a worm gear connected to the lead screw, a worm driven by the worm gear, a driven gear for driving the worm to rotate, and a displacement assembly connected to the driven gear. The drive motor is provided with a driving gear, and the displacement assembly can drive the driven gear to move. When the displacement assembly drives the driven gear away from the driving gear, the driven gear and the driving gear are not meshed. When the displacement assembly drives the driven assembly to move towards the driving gear, the driven gear and the driving gear mesh.

[0009] The positive and negative lead screws are rotatably connected within the groove;

[0010] The worm gear is rotatably connected to the drive slot.

[0011] Furthermore, each set of grippers consists of two grippers, and each gripper has a telescopic rod on its upper side. The other end of the telescopic rod is provided with a clamping plate. The two clamping plates are threadedly connected to the two ends of the positive and negative threaded screws, so that when the positive and negative threaded screws rotate, the two grippers in the same set move relative to each other or away from each other.

[0012] Furthermore, a circular through hole is provided at the center of the upper side of the driven gear, and teeth are provided along the circumferential side of the circular through hole. A gear is provided at the upper end of the worm gear and located in the circular through hole. When the displacement component drives the driven gear away from the driving gear, the teeth on the circular through hole do not mesh with the gear. When the displacement component drives the driven gear to move towards the driving gear, the teeth on the circular through hole mesh with the gear.

[0013] Furthermore, the displacement component includes a guide frame disposed on the upper side of the clamping block, an adjustment block slidably connected to the inner side of the guide frame, and an electric telescopic rod disposed on the side of the guide frame away from the driving gear. The electric telescopic rod is disposed on the clamping block, and the driven gear is rotatably connected to the adjustment block. The electric telescopic rod can drive the driven gear away from the driving gear or cooperate with the driving gear.

[0014] Furthermore, the displacement adjustment assembly includes two support frames, two slide plates connected to the two support frames at both ends, a longitudinal slider slidably connected to the slide plate, a longitudinal displacement plate connected to the two longitudinal sliders, a linear motor connected to the longitudinal displacement plate, a transverse displacement plate slidably connected to the lower side of the longitudinal displacement plate, and a telescopic assembly disposed on the transverse displacement plate. The two ends of the linear motor are fixed to the two support frames. The transverse displacement plate is provided with a linear motor connected to the longitudinal displacement plate to drive the transverse displacement plate to move laterally. The telescopic assembly is connected to a connecting frame located on the upper side of the clamping block.

[0015] Furthermore, the telescopic assembly includes a lifting telescopic rod rotatably connected to a transverse displacement plate and a rotary motor for driving the lifting telescopic rod to rotate. The rotary motor is connected to the transverse displacement plate, and the other end of the lifting telescopic rod is connected to a connecting frame.

[0016] Furthermore, a connector is provided at the end of the lifting telescopic rod away from the connecting frame. The connector has a circular hole and at least one limiting groove is provided on the circumferential side of the circular hole along the axial direction. Both sides of the connector are provided with hinge plates located on the transverse displacement plate. The hinge plate is rotatably connected to a plug shaft inserted into the circular hole. The plug shaft is provided with a limiting protrusion inserted into the limiting groove. The rotary motor is connected to one of the plug shafts.

[0017] Furthermore, one of the hinge plates is slidably connected to the transverse displacement plate, and the hinge plate is provided with a fixing member fixed to the transverse displacement plate. When the hinge plate slides, the insertion shaft disengages from the limiting groove.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This invention achieves simultaneous and individual driving of three sets of grippers through the cooperation of the drive motor and transmission components, which facilitates the simultaneous clamping of multiple shock absorber components and the individual injection of lubricating oil, thereby improving production efficiency;

[0020] 2. The present invention uses a displacement component to realize the displacement adjustment of the driven component, thereby realizing the drive control of the worm gear, which facilitates the clamping and releasing control of one or more grippers.

[0021] 3. The invention uses a worm gear structure so that when the worm and the drive gear are not driving, the forward and reverse lead screws will not rotate, thus preventing the grippers from loosening when holding the shock absorber components.

[0022] In summary, this invention has the advantage of improving production efficiency. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figure 1-7 As shown, an automatic conveying device for a shock absorber production line includes a conveyor line 1, specifically a chain ring-loop conveyor line 1. A placement plate 2 for three shock absorber components is connected to the chain ring-loop conveyor line 1. The conveyor line 1 is equipped with two identical loading and unloading devices 8 and a clamping and transferring device. The clamping and transferring device includes a displacement adjustment component and a clamping block 23 disposed on the displacement adjustment component, a drive motor 19 fixed to the clamping block 23 by bolts, three sets of clamping claws 16 arranged side by side on the clamping block 23, and three transmission components that can drive the drive motor 19. The displacement adjustment component can drive the clamping block 23 to perform multi-directional displacement adjustment. The transmission components are disposed on the clamping block 23. When the drive motor 19 is working, the drive motor 19 drives one or more sets of clamping claws 16 to work through the transmission components. The three shock absorber components located on the placement plate 2 are located below the three clamping claws 16.

[0033] In use, the loading and unloading device 8 places three shock absorber components on the placement plate 2. Then, the conveyor line 1 operates, driving the placement plate 2 to move. When the placement plate 2 is below the clamping and transferring device, the conveyor line 1 stops, and the placement plate 2 no longer moves. At this time, the displacement adjustment component drives the clamping block 23 to move above the placement plate 2, and then moves the clamping block 23 down until the three shock absorber components are located between the three grippers 16. At this time, the drive motor 19 operates and drives the three grippers 16 to clamp the shock absorber components through the transmission component. Then, the displacement adjustment component drives the shock absorber components to the refueling device, and then the clamping plate 17 clamps the rotating shock absorber components, making the shock absorber components vertical. After that, the displacement adjustment component drives one of the shock absorber components to move into the refueling device. At this time, the drive motor 19 reverses, making the three grippers 16 clamp the three grippers 16. The gripper 16 in the refueling device releases the shock absorber component, and the displacement adjustment component moves the gripper 16 to one side of the refueling device. At this time, the refueling device injects lubricating oil into the shock absorber component. After the injection is completed, the displacement adjustment component moves the gripper 16, which is in the open state, so that the shock absorber component is located between the grippers 16. The drive motor 19 rotates in the forward direction, the gripper 16 clamps the shock absorber component, and the displacement adjustment component moves another shock absorber component into the refueling device. Then, lubricating oil is added one by one according to the above process. After the lubricating oil is added to the three shock absorber components, the displacement adjustment component uses the gripper 16 to place the shock absorber component back on the placement plate 2. Then the conveyor line 1 works, so that the next placement plate 2 is moved below the gripper 16. Then, lubricating oil is added to the shock absorber components according to the above steps.

[0034] For shock absorber parts that require lubrication, the loading and unloading device 8 removes them from the placement plate 2 of the conveyor line 1.

[0035] In this embodiment, the lower side of the clamping block 23 has three grooves 35, the upper side of the clamping block 23 has three drive grooves 32, the three drive grooves 32 are respectively disposed between the three grooves 35, and the three sets of grippers 16 are individually disposed in the three grooves 35.

[0036] In this embodiment, the transmission assembly includes a positive and negative threaded screw 36 separately connected to a set of grippers 16, a worm wheel 33 connected to the positive and negative threaded screw 36, a worm 26 driven by the worm wheel 33, a driven gear 24 for driving the worm 26 to rotate, and a displacement assembly connected to the driven gear 24. The drive motor 19 is key-connected to a drive gear 25. The displacement assembly can drive the driven gear 24 to move. When the displacement assembly drives the driven gear 24 away from the drive gear 25, the driven gear 24 and the drive gear 25 are not meshed. When the displacement assembly drives the driven assembly to move towards the drive gear 25, the driven gear 24 and the drive gear 25 mesh.

[0037] A through hole is provided between the groove 35 and the drive groove 32. A bearing is fixed in the through hole. The worm gear 33 is keyed to a rotating shaft. The opposite ends of the rotating shaft and the positive and negative threaded screws 36 are fixed in the drive groove 32 and the groove 35 respectively by bearings. The other ends of the positive and negative threaded screws 36 and the rotating shaft are connected to the bearing in the through hole so that the rotating shaft can drive the positive and negative threaded screws 36 to rotate.

[0038] When the gripper 16 needs to clamp, the displacement component drives the driven gear 24 to move toward the driving gear 25 until the driven gear 24 meshes with the driving gear 25. At this time, the driven gear 24 can drive the worm 26 to rotate, and the drive motor 19 works and drives the positive and negative threaded screw 36 to rotate clockwise through the driving gear 25, the driven gear 24, the worm 26, the worm wheel 33 and the rotating shaft. As the positive and negative threaded screw 36 rotates clockwise, the gripper 16 connected to the positive and negative threaded screw 36 moves relative to it until the gripper 16 clamps the shock absorber components, and then the motor stops.

[0039] When the drive gripper 16 is released, the drive motor 19 can be reversed.

[0040] When one gripper 16 needs to work, the displacement components corresponding to the other two grippers 16 are controlled to drive the driven gear 24 to move away from the driving gear 25, so that the driven gear 24 does not mesh with the driving gear 25. When the driven gear 24 does not mesh with the driving gear 25, the worm gear 33 and worm 26 structure prevents the positive and negative thread screw 36 from rotating, thereby ensuring the clamping of the gripper 16.

[0041] In this embodiment, each set of grippers 16 consists of two grippers, and the upper sides of the two grippers 16 are connected by two telescopic rods 15 by bolts. A clamping plate 17 is provided above the other end of the telescopic rod 15. The telescopic rod 15 is embedded in the clamping plate 17. The clamping plate 17 has threaded holes and guide holes. The threaded holes of the two clamping plates 17 are threaded to the two ends of the positive and negative threaded screws 36, so that when the positive and negative threaded screws 36 rotate, the two grippers 16 of the same set move relative to each other or away from each other. A guide rod 34 is also provided in the groove 35, and the guide rod 34 passes through the guide hole.

[0042] When it is necessary to move the clamp, the clamping plate 17 moves relative to the rotation of the positive and negative threaded screws 36 until they fit together. When it is released, the positive and negative threaded screws 36 can be flipped. When one of the jaws 16 needs to be extended, it can be extended by controlling the extension rod 15.

[0043] The telescopic rod 15 specifically refers to telescopic components such as an electric push rod.

[0044] In this embodiment, a circular through hole is provided at the center of the upper side of the driven gear 24. The circular through hole is integrally formed with teeth along the circumferential side. The upper end of the worm gear 26 is keyed to a gear located in the circular through hole. When the displacement component drives the driven gear 24 away from the driving gear 25, the teeth on the circular through hole do not mesh with the gear. When the displacement component drives the driven gear 24 to move towards the driving gear 25, the teeth on the circular through hole mesh with the gear.

[0045] In use, the transmission is achieved through the gear and the teeth on the circular through hole, ensuring the transmission between the worm 26 and the driven gear 24.

[0046] In this embodiment, the displacement assembly includes a guide frame 14 fixed to the upper side of the clamping block 23 by bolts, an adjusting block 28, and an electric telescopic rod 27 disposed on the side of the guide frame 14 away from the driving gear 25. The inner side of the guide frame 14 is provided with two sliding grooves. The sliding direction of the sliding grooves is the same as the direction of the axis of the worm gear 26 toward the driving gear 25. The adjusting block 28 is fixed with a slider located in the sliding groove. The driven gear 24 is connected to the adjusting block 28 through a bearing. The electric telescopic rod 27 can drive the driven gear 24 away from the driving gear 25 or cooperate with the driving gear 25. The electric telescopic rod 27 is fixed to the clamping block 23 by bolts.

[0047] When it is necessary to control the driven gear 24 to move toward the driving gear 25, the output shaft of the electric telescopic rod 27 is extended, and the electric telescopic rod 27 pushes the adjusting block 28 to drive the driven gear 24 to move toward the driving gear 25. When it is necessary to control the driven gear 24 to move away from the driving gear 25, the output shaft of the electric telescopic rod 27 is retracted.

[0048] In use, the slider and groove prevent the driven gear 24 from shifting during movement, thus ensuring the engagement between the driven gear 24 and the driving gear 25.

[0049] In this embodiment, the displacement adjustment assembly includes two support frames 5, two slide plates 4 whose two ends are bolted to the two support frames 5, a longitudinal slider 7 slidably connected to the slide plate 4, a longitudinal displacement plate 6 bolted to the two longitudinal sliders 7, a linear motor 3 connected to the longitudinal displacement plate 6, a transverse displacement plate 11, and a telescopic assembly disposed on the transverse displacement plate 11. The two ends of the linear motor 3 are fixed to the two support frames 5 by bolts. Two parallel slide grooves are opened on the lower side of the longitudinal displacement plate 6. A transverse slider 22 located in the slide groove is fixed to the transverse displacement plate 11 by bolts. A linear motor 10 is fixed to the transverse displacement plate 11 by bolts. An installation groove located between the two slide grooves is opened on the lower side of the longitudinal displacement plate 6. The linear motor 10 is fixed to the installation groove by bolts to drive the transverse displacement plate 11 to move laterally. The telescopic assembly is connected to a connecting frame 18 bolted to the upper side of the clamping block 23.

[0050] In use, the longitudinal displacement plate 6 and the lateral displacement plate 11 are driven by linear motor 3 and linear motor 2 10 to make longitudinal and lateral adjustments, which facilitates adjustment.

[0051] In this embodiment, the telescopic assembly includes a lifting telescopic rod 20 rotatably connected to the transverse displacement plate 11 and a rotary motor 21 for driving the lifting telescopic rod 20 to rotate. The rotary motor 21 is bolted to the transverse displacement plate 11, and the other end of the lifting telescopic rod 20 is bolted to the connecting frame 18.

[0052] In use: The lifting telescopic rod 20 is rotated and adjusted by the rotating motor 21, and the extension and retraction of the gripper 16 is adjusted by the lifting telescopic rod 20, thereby realizing the multi-directional displacement adjustment of the gripper 16.

[0053] In this embodiment, the end of the lifting telescopic rod 20 away from the connecting frame 18 is fixed with a connector 12 by bolts. The connector 12 has a circular hole and at least one limiting groove is provided on the circumferential side of the circular hole along the axial direction. Both sides of the connector 12 are provided with hinge plates 13 located on the transverse displacement plate 11. The hinge plates 13 are connected to the insertion shaft 31 inserted into the circular hole by bearings. The insertion shaft 31 is integrally formed with a limiting protrusion inserted into the limiting groove. The rotary motor 21 is keyed to one of the insertion shafts 31.

[0054] In use, the rotary motor 21 drives the lifting telescopic rod 20 to rotate through the plug shaft 31, the limiting protrusion, the limiting groove and the connector 12 to ensure rotational adjustment;

[0055] In this embodiment, a sliding groove is provided on the lower side of the transverse displacement plate 11, and an adjusting slider 30 is provided in the sliding groove. One of the hinge plates 13 is connected to the adjusting slider 30 by bolts. A fixing member is provided on the hinge plate 13 and fixed to the transverse displacement plate 11. When the hinge plate 13 slides, the insertion shaft 31 disengages from the limiting groove.

[0056] When using the device, if the lifting telescopic rod 20 needs to be removed, the fixing part is no longer fixed to the transverse displacement plate 11. Then, the hinge plate 13 drives the insertion shaft 31 to move until the insertion shaft 31 is no longer inserted into the round hole. Then, the lifting telescopic rod 20 can be removed from the other insertion shaft 31. When it needs to be installed, the lifting telescopic rod 20 is inserted into one of the insertion shafts 31. Then, the hinge plate 13 is moved until the other insertion shaft 31 is inserted into the round hole. After the insertion is completed, the fixing part is fixed to the transverse displacement plate 11.

[0057] The fastener is specifically a bolt.
