Description

Technical Field

[0001] This utility model relates to the field of material handling technology for ultra-precision machines, and in particular to a material handling component for a bearing ultra-precision machine. Background Technology

[0002] In the manufacturing process of rolling bearings, ultra-precision is the final process for machining bearing rings. It plays an important role in reducing or eliminating circular deviations left by grinding, repairing the shape errors of the raceway, refining its surface roughness, improving the surface physical and mechanical properties, reducing bearing vibration and noise, and increasing bearing life.

[0003] The patent, published under the number CN114178946B and titled "Ultra-precision Machine for Bearing Inner Ring Grooves," includes a machine base with a frame mounted on its surface. A bearing ultra-precision headstock assembly is mounted on the frame, and a feeding assembly is connected above the headstock assembly. Rotatable upper and lower rollers are mounted at the front end of the headstock assembly. A pusher rod is located at the bottom of the feed channel. The bearing inner ring is fed into the space between the upper and lower rollers by the feeding assembly. A main shaft is mounted on the machine base. A connecting plate and a bearing ultra-precision swing arm assembly are sequentially mounted on the upper end of the main shaft. A main shaft drive motor is connected to one side of the frame, driving the bearing ultra-precision swing arm assembly. A support column is mounted on the machine base, with a bearing clamping assembly mounted on one side and a bearing discharge assembly mounted on the other.

[0004] In the aforementioned patent, the device uses a bearing clamping assembly to pick up the bearing and place it at the processing area. The bearing picking mechanism needs to put down the clamped bearing before it can pick up a new bearing to be processed from the feeding assembly, resulting in low picking efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a bearing ultra-precision machine material handling component, which can clamp the bearing in the ultra-precision machine's loading component and wait for it to be moved to the processing area for unloading when the clamped bearing is placed at the processing area, thereby improving material handling efficiency.

[0006] To achieve the above objectives, a bearing ultraprecision machine material handling assembly is provided, comprising a base, a first groove circumferentially formed around the center of the outer side of the base, a second groove formed on the upper surface of the base, two sprockets symmetrically arranged at the upper end of the base and rotatably connected to the base, a drive chain connected end-to-end mounted on the surfaces of the two sprockets and surrounded by the second groove, the drive chain consisting of several inner chain plates, outer chain plates, and pins, two material handling mechanisms symmetrically mounted on the surface of the drive chain and mounted on the outer chain plates, the material handling mechanisms cooperating with the first and second grooves, a motor and two support frames fixedly connected to the lower end of the base, the motor's rotating shaft passing upward through the base and fixedly connected to the center of the sprockets. This assembly can clamp the bearing in the ultraprecision machine's loading assembly and wait for it to move to the processing area for unloading when the clamped bearing is placed at the processing area, thereby improving material handling efficiency.

[0007] According to the aforementioned bearing ultra-precision machine material handling assembly, the material handling mechanism comprises a first cylinder, a first mounting plate, a second cylinder, a connecting member, a first guide post, a second guide post, a second mounting plate, and a gripper. The connecting member is located on the outside of the transmission chain and is fixedly connected to the outer chain plates on both sides of the transmission chain. The first guide post passes through the middle of the connecting member and is fixedly connected to the connecting member. The bottom of the first guide post enters the second slide groove and is slidably connected to the second slide groove. The second mounting plate is fixedly connected to the upper end of the first guide post. The second cylinder is fixedly connected to the side of the second mounting plate facing the transmission chain, and the piston rod of the second cylinder passes through the second mounting plate. The first mounting plate is fixedly connected to the piston rod of the second cylinder. The first cylinder is fixedly connected to the upper end of the first mounting plate, and the piston rod of the first cylinder passes downward through the first mounting plate. The gripper is fixedly connected to the bottom of the piston rod of the first cylinder, and the gripping end of the gripper is away from the transmission chain. The second guide post is fixedly connected to the bottom of the second mounting plate, and the second guide post is located on the outside of the base. The connector allows the material handling mechanism to be mounted on the transmission chain, which in turn drives the material handling mechanism to move. The first cylinder adjusts the height of the gripper, and the second cylinder pushes the gripper to extend. The first and second cylinders work together to allow the gripper to hold the bearing.

[0008] According to the aforementioned bearing ultra-precision machine material handling assembly, a mounting bracket is fixedly connected to the upper end of the base, and the mounting bracket is disposed inside the transmission chain. A positioning detection sensor is fixedly connected to the upper end of the mounting bracket. The positioning detection sensor is used to detect whether the material handling mechanism is in position. The positioning detection sensor is used to detect whether the material handling mechanism is in position, ensuring that the gripper can grip the bearing.

[0009] According to the aforementioned bearing ultra-precision machine material handling assembly, a second roller is fitted onto the outer surface of the first guide post, and the second roller is disposed in a second groove and contacts the side wall of the second groove. A ball bearing is embedded at the lower end of the first guide post, and the ball bearing rolls at the bottom of the second groove. The second roller replaces the first guide post in contacting the side wall of the second groove, and the ball bearing supports the first guide post, reducing wear on the second groove.

[0010] According to the aforementioned bearing ultra-precision machine material handling assembly, a monitoring camera is mounted on the first mounting plate, and the monitoring camera is positioned directly above the gripper. The monitoring camera is used to follow the movement of the gripper, enabling the gripper to automatically grasp the bearing.

[0011] According to the aforementioned bearing ultra-precision machine material handling assembly, the gripper includes a housing and grippers. Two grippers are symmetrically arranged at the bottom of the housing. A monitoring camera is positioned between the two grippers. The lower end of the piston rod of the first cylinder is fixedly connected to the middle of the upper end of the housing. The monitoring camera monitors the operation of the grippers to ensure that the gripper securely holds the bearing.

[0012] According to the aforementioned bearing ultra-precision machine material handling assembly, a first roller is fitted onto the surface of the second guide post, and the outer surface of the first roller rolls against the inner wall of the first groove. The first roller, in conjunction with the second guide post, improves the stability of the material handling mechanism during movement and supports the transmission chain, preventing fluctuations in the material handling mechanism caused by a loose transmission chain.

[0013] According to the aforementioned bearing ultra-precision machine material handling assembly, a controller is fixedly connected to the upper end of the base, and the controller is located inside the transmission chain. The controller receives and processes data collected by the positioning detection sensor and the monitoring camera, and controls the motor, the first cylinder, the second cylinder, and the gripper.

[0014] The above-mentioned solution has the following beneficial effects:

[0015] 1. The motor drives the transmission chain through the sprocket, and the two material handling mechanisms on the transmission chain move. When one material handling mechanism places the clamped bearing at the processing position, the other material handling mechanism clamps the bearing in the feeding assembly of the ultra-precision machine and waits to move it to the processing position for unloading, thereby improving material handling efficiency.

[0016] 2. The material handling mechanism is supported by the cooperation of the first roller and the first groove on the second guide column, and the cooperation of the second roller, the ball and the second groove on the first guide column, thus avoiding instability when the material handling mechanism moves due to a loose transmission chain.
