Description

Technical Field

[0001] This invention relates to the field of loading and unloading devices, specifically an automatic loading and unloading device for precision grinding of the outer diameter of a linear bearing outer sleeve. Background Technology

[0002] The automatic loading and unloading device for precision grinding of the outer diameter of linear bearing outer sleeve is a special tooling equipment applied to the precision grinding process of the outer diameter of linear bearing outer sleeve. It can automatically complete the workpiece loading and conveying, positioning and clamping, feeding at the grinding machine station, and unloading and outputting the workpiece after grinding. It replaces manual clamping and picking, realizes the automated flow of the outer sleeve on the precision grinding equipment, reduces manual intervention, and improves the consistency of loading and production efficiency in the precision grinding of the outer diameter. Current loading and unloading devices use rigid grippers, making it difficult to precisely control the clamping force. Excessive clamping force can cause elastic compression deformation of the thin-walled outer sleeve, resulting in poor outer diameter roundness. Insufficient clamping force can cause the workpiece to slip and fall during high-speed transport. At the same time, since the sleeve is a cylindrical workpiece, it is prone to rolling and posture deviation when it is fed to the grinding machine pallet / support roller station, resulting in a misalignment between the workpiece center and the grinding machine machining center.

[0003] Therefore, an automatic loading and unloading device for precision grinding of the outer diameter of linear bearing sleeves is needed to improve the above-mentioned problems. Summary of the Invention

[0013] As a preferred embodiment of the present invention, a foot support is fixedly installed at the bottom corner of the equipment platform, the lifting holes are in pairs and located on both sides of the clamping housing, and the lifting holes are located directly above the moving end of the lifting device. The controller is connected to the electrically controlled rotating base, the lifting device, the detection and identification sensor, the electrically controlled cylinder, the reciprocating horizontal push cylinder, the electrically controlled gripper and the electrically controlled magnet through wires, and the connection method is electrical connection.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention enables adaptive clamping of the bearing outer sleeve by incorporating an automatic loading and unloading component in the precision grinding process of the outer diameter of the linear bearing outer sleeve. An electrically controlled cylinder drives the mounting plate to reciprocate longitudinally along the limiting support, thereby moving the gripper structure to achieve the loading and unloading displacement of the bearing outer sleeve. Upon reaching the loading / unloading position, the controller activates a reciprocating horizontal push cylinder, which pulls a rotating shaft via a tie rod. This rotating shaft then moves the mounting block and the electrically controlled gripper to the side of the bearing outer sleeve for clamping. A flexible pad prevents slippage when the electrically controlled gripper is clamping the workpiece. When the workpiece comes into contact with the pressure sensor, a pressure signal is generated and fed back to the controller. The controller adjusts the magnetic strength of the electromagnet according to the preset pressure parameters. The electromagnet outputs a magnetic thrust to the magnetic limit block, and works in conjunction with the limit spring to elastically limit the clamping plate. This allows the clamping plate to adjust the clamping force on the bearing outer sleeve in real time according to the pressure feedback for automatic loading and unloading. This solves the problems of rigid grippers gripping, where it is difficult to accurately control the clamping force, and excessive clamping force can easily cause elastic extrusion deformation of the thin-walled outer sleeve, resulting in poor outer diameter roundness; while insufficient clamping force can cause the workpiece to slip and fall during high-speed transfer.

[0015] 2. This invention enables the positioning and fixing of the bearing outer sleeve by setting a sleeve fixing component in the automatic loading and unloading device for precision grinding of the outer diameter of the linear bearing outer sleeve. By placing the bearing outer sleeve on the outer wall of the clamping housing, it is only necessary to release the ejector block, which then allows the strong magnet to push the magnetic limiting block laterally, causing the magnetic limiting block to slide outward on the inner wall of the limiting slot. Since there are multiple sets of ejector blocks, each set of ejector blocks will push the bearing outer sleeve outward, thereby ejecting and fixing the bearing outer sleeve. This ensures that the bearing outer sleeve and the clamping housing remain concentric, facilitating subsequent clamping and loading processing. This solves the problem that when the sleeve is a cylindrical workpiece, it is easy for it to roll, deflect, and the coaxiality of the workpiece center with the grinding machine processing center to deviate when it is fed to the grinding machine pallet / support roller station.

[0016] 3. This invention enables automatic loading and unloading of the bearing outer sleeve by setting a detection and identification sensor in the automatic loading and unloading device for precision grinding of the outer diameter of the linear bearing outer sleeve. The bearing outer sleeve, which is clamped to the outer wall of the housing, is lifted by a lifting device passing through a lifting hole. The controller controls the operation of the detection and identification sensor so that the detection and identification sensor can identify and detect the bearing outer sleeve. At the same time, the detection and identification sensor generates an electrical signal that is transmitted to the controller through a wire. When the preset parameters are reached, the controller will control the automatic loading and unloading component to automatically load and unload the material. Attached Figure Description

A sleeve base 713 is embedded in the outer wall of the clamping plate 712.

[0023] In this embodiment, specific references Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5A limiting rod 714 is slidably connected to the inner wall of the sleeve base 713. A clamping block 715 is fixedly installed at one end of the limiting rod 714. A flexible pad 716 is fixedly installed on the outer wall of one side of the clamping block 715.

The electrically controlled magnet 720 is located on one side of the magnetic limiting block 718, and the electrically controlled magnet 720 generates magnetism when energized to limit the magnetic limiting block 718.

[0024] Among them, a foot support 9 is fixedly installed at the bottom corner of the equipment platform 1, and the lifting holes 5 are in pairs and located on both sides of the clamping housing 603, and the lifting holes 5 are located directly above the moving end of the lifting device 8. Based on the above structural features and connection relationships, the moving end of the electric cylinder 704 pushes the mounting plate 703 to move longitudinally, thereby causing the mounting plate 703 to reciprocate longitudinally on the outer wall of the limiting support 702. This allows the mounting plate 703 to move the gripper structure to load and unload the bearing outer sleeve. When it moves to the loading and unloading position, the controller 2 will control the reciprocating horizontal push cylinder 707 to operate, causing the reciprocating horizontal push cylinder 707 to rotate on the outer wall of the mounting plate 703. At the same time, one end of the reciprocating horizontal push cylinder 707 reciprocates by pulling the rotating shaft 709 through the pull rod 708, thereby causing the rotating shaft 709 to drive the mounting block 710 to reciprocate. Simultaneously, the mounting block 710 drives the electric gripper 711 to move to the side of the bearing outer sleeve for clamping. The controller 2 is electrically connected to the electrically controlled rotating base 3, the lifting device 8, the detection and identification sensor 706, the electrically controlled cylinder 704, the reciprocating horizontal thrust cylinder 707, the electrically controlled gripper 711, and the electrically controlled magnet 720 via wires. This electrically connected device is powered on, and the controller 2 controls the electrically controlled rotating base 3, the lifting device 8, the detection and identification sensor 706, the electrically controlled cylinder 704, the reciprocating horizontal thrust cylinder 707, the electrically controlled gripper 711, and the electrically controlled magnet 720 to operate.

[0025] In this automatic loading and unloading device for precision grinding of the outer diameter of linear bearing outer sleeve, the bearing outer sleeve is placed on the outer wall of the clamping housing 603 by pinching the ejector block 607. Releasing the ejector block 607 allows the strong magnet 605 to magnetically push the limiting magnetic block 608 laterally, causing the limiting magnetic block 608 to slide outwards on the inner wall of the limiting slot 606. Since multiple sets of ejector blocks 607 are provided, each set pushes the bearing outer sleeve outwards, thus limiting and fixing the bearing outer sleeve. This ensures that the bearing outer sleeve and the clamping housing 603 remain concentric, facilitating subsequent clamping and loading processing. This solves the problem that cylindrical workpieces are prone to rolling, posture deviation, and coaxiality deviation between the workpiece center and the grinding machine machining center when being fed to the grinding machine pallet / support roller station. By turning on the switch of the controller 2 and setting the preset parameters, the controller 2 controls the electric rotating base 3 to operate, so that the rotating end of the electric rotating base 3 drives the rotating platform 4 to rotate to the loading and unloading position. When the preset position is reached, the controller 2 controls the lifting device 8 to operate, so that one end of the lifting device 8 passes through the lifting hole 5 and moves upward, thereby lifting the bearing outer sleeve of the clamping housing 603 through the lifting hole 5. At the same time, the controller 2 controls the detection and identification sensor 706 to operate, so that the detection and identification sensor 706 identifies and detects the bearing outer sleeve. At the same time, the detection and identification sensor 706 generates an electrical signal that is transmitted to the controller 2 through the wire. When the preset parameters are reached, the controller 2 controls the automatic loading and unloading assembly 7 to automatically load and unload materials according to the materials. The moving end of the electrically controlled cylinder 704 pushes the mounting plate 703 to move longitudinally, thereby causing the mounting plate 703 to reciprocate longitudinally on the outer wall of the limiting support 702. This allows the mounting plate 703 to move the gripper structure to load and unload the bearing outer sleeve. When it reaches the loading / unloading position, the controller 2 controls the reciprocating horizontal push cylinder 707 to operate, causing the reciprocating horizontal push cylinder 707 to rotate on the outer wall of the mounting plate 703. At the same time, one end of the reciprocating horizontal push cylinder 707 reciprocates by pulling the rotating shaft 709 through the pull rod 708, thereby causing the rotating shaft 709 to drive the mounting block 710 to reciprocate. Simultaneously, the mounting block 710 drives the electrically controlled gripper 711 to move to one side of the bearing outer sleeve for clamping. When the bearing outer sleeve is clamped by the electrically controlled gripper 711, the flexible pad 716 acts as an anti-slip device, causing the bearing outer sleeve to come into contact with the pressure sensor 717 and generate pressure. This pressure sensor 717 then generates an electrical signal, which is transmitted to the controller 2 via a wire. Based on preset pressure parameters, the controller 2 controls the electrically controlled magnet 720 to operate, thereby adjusting the magnetic strength of the electrically controlled magnet 720. This results in the electrically controlled magnet 720 generating a magnetic pushing force on the magnetic limit block 718, while the limit spring 719 pulls. The movable clamping plate 712 is limited. Due to the elastic limitation of the clamping plate 712 by the limiting spring 719, and the magnetic thrust generated by the electro-magnet 720 on the magnetic limiting block 718, the clamping plate 712 can adjust the clamping force in real time according to the pressure value when clamping the bearing outer sleeve. This solves the problems of rigid grippers gripping, where the clamping force is difficult to control accurately, excessive clamping force can easily cause elastic extrusion deformation of the thin-walled outer sleeve, resulting in poor outer diameter roundness; and insufficient clamping force can cause the workpiece to slip and fall during high-speed transfer.
