Abstract
Description
Technical Field
[0001] This utility model relates to a turning device, specifically an automatic loading and unloading turning device for automotive bearing rings, belonging to the technical field of automotive parts processing equipment. Background Technology
[0002] Bearing races require machining of their end faces to create stepped surfaces, facilitating subsequent installation. Traditional turning equipment typically uses two symmetrically arranged clamping tools to restrain the bearing races from both the front and rear ends, then rotates at high speed in conjunction with an external cutting tool for machining. In existing technology, this type of turning equipment generally involves manual loading and unloading, which poses certain risks and requires constant operator supervision and frequent replacement, resulting in significant waste of human resources. A few turning devices with robotic arms exist, using grippers to grasp the workpiece; however, this robotic arm method demands extremely high precision control of the gripper, leading to high costs and hindering its widespread adoption. Therefore, a compromise device is needed that can replace manual loading and unloading while keeping costs within an acceptable range. Utility Model Content
[0003] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose an automatic loading and unloading turning device for automotive bearing rings, which reduces manual intervention, saves human resources, lowers production costs, and improves the efficiency of the turning process.
[0004] An automatic loading and unloading turning device for automotive bearing rings includes a turning fixture; a clamping head is provided inside the turning fixture; a cutting tool is provided on one side of the clamping head, and a material unloading box is provided on the other side of the clamping head; a material unloading guide groove is provided on the side of the material unloading box near the turning fixture; a feeding guide groove is connected to the upper part of the material unloading guide groove; an indexing mechanism is provided at the end of the feeding guide groove; the material unloading guide groove is disposed on a sliding table; the sliding table is disposed inside the material unloading box; a rotating mechanism is connected between the sliding table and the material unloading guide groove; the material unloading guide groove and the sliding table are rotatably connected.
[0005] Furthermore, a vertical plate is provided on the sliding platform; one end of the feeding guide groove is rotatably connected to the vertical plate; a ball screw nut is provided at the bottom of the sliding platform; a ball screw is provided inside the feeding box; the ball screw is connected to the first motor; the first motor is located outside the feeding box.
[0006] Furthermore, the rotating mechanism includes a cylinder; the cylinder is disposed on the surface of the sliding table; the rotating mechanism also includes a first connecting rod and a second connecting rod; the first connecting rod is fixedly connected to the bottom of the feeding guide groove; the second connecting rod is hinged to the cylinder piston; the second connecting rod is rotatably connected to the first connecting rod.
[0007] Furthermore, the feeding box is provided with a bearing ring storage cavity; an entry groove is opened on one side of the bearing ring storage cavity opposite the feeding guide groove; the two ends of the feeding guide groove are open.
[0008] Furthermore, one end of the feed guide trough is closed, and the other end is open; the indexing mechanism is located at the open end of the feed guide trough; the indexing mechanism includes an indexing plate; the axial direction of the indexing plate is consistent with the width direction of the feed guide trough.
[0009] Furthermore, a second motor is provided on the outside of the feed guide groove; the second motor is connected to the indexing plate; and a number of bearing rings to be processed are arranged inside the feed guide groove.
[0010] This utility model has the following advantages: the unloading guide groove and the loading guide groove are jointly arranged on the sliding table, which is located inside the unloading box. When unloading and loading operations need to be performed simultaneously, the sliding table can drive the unloading guide groove to move below the two clamping heads to receive the unloading workpiece. Then, the two clamping heads separate, and the unloading workpiece naturally falls into the unloading guide groove and rolls along it into the bearing ring storage cavity. Immediately afterwards, the rotating mechanism controls the unloading guide groove and the loading guide groove to rotate downwards simultaneously, so that the end of the loading guide groove is between the two clamping heads, and the unloading guide groove is away from the clamping heads. At this time, the indexing mechanism starts to work, the indexing plate rotates, and one indexing cell of the indexing plate contains the loading workpiece. As the indexing plate rotates, it will rotate the loading workpiece between the two clamping heads, waiting for the two clamping heads to clamp it. The subsequent loading workpieces will roll into the next indexing cell of the indexing plate in sequence, waiting for the next loading. After the unloading and loading processes are completed, the sliding table moves the unloading guide chute and loading guide chute back into the unloading box, providing space for the cutting tools. The above process is then repeated for the next unloading and loading cycle, until the workpiece in the loading guide chute is finished and manually replenished. Using this method, the unloading and loading guide chute can be set in predetermined positions and then allowed to cycle continuously. Compared to a robotic arm, this method requires lower control precision and reduces costs. Furthermore, it minimizes human intervention, requiring only periodic replenishment.

Detailed Implementation
[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0017] See Figures 1-4 This application discloses an automatic loading and unloading turning device for automotive bearing rings, including a turning fixture 1; a clamping head 2 is provided inside the turning fixture 1; a cutting tool 3 is provided on one side of the clamping head 2, and a feeding box 4 is provided on the other side of the clamping head 2; a feeding guide groove 5 is provided on the side of the feeding box 4 near the turning fixture 1; a feeding guide groove 6 is connected to the upper part of the feeding guide groove 5; an indexing mechanism is provided at the end of the feeding guide groove 6; the feeding guide groove 5 is disposed on a sliding table 7; the sliding table 7 is disposed inside the feeding box 4; a rotating mechanism is connected between the sliding table 7 and the feeding guide groove 5; the feeding guide groove 5 and the sliding table 7 are rotatably connected.
[0018] Furthermore, the sliding table 7 is provided with a vertical plate 7-1; one end of the feeding guide groove 5 is rotatably connected to the vertical plate 7-1; a ball screw nut 7-2 is provided at the bottom of the sliding table 7; a ball screw 4-1 is provided inside the feeding box 4; the ball screw 4-1 is connected to the first motor 8; the first motor 8 is located outside the feeding box 4.
[0019] Furthermore, the rotating mechanism includes a cylinder 9; the cylinder 9 is disposed on the surface of the sliding table 7; the rotating mechanism also includes a first connecting rod 10 and a second connecting rod 11; the first connecting rod 10 is fixedly connected to the bottom of the feeding guide groove 5; the second connecting rod 11 is hinged to the piston of the cylinder 9; the second connecting rod 11 is rotatably connected to the first connecting rod 10.
[0020] Specifically, in this embodiment, the unloading guide 5, the feeding guide 6, and the rotating mechanism are all mounted on the sliding table 7. The sliding table 7 is driven by the ball screw nut 7-2 and the ball screw 4-1 to perform a translational movement, thereby causing the unloading guide 5 and the feeding guide 6 to move closer to or further away from the clamping head 2. After the workpiece is unloaded through the unloading guide 5, the cylinder 9 pulls the second connecting rod 11, thereby rotating the unloading guide 5 and the feeding guide 6 downwards, so that the feeding guide 6 moves closer to the clamping head 2, facilitating feeding.
[0021] Furthermore, the feeding box 4 is provided with a bearing ring storage cavity 4-2; an entry groove 4-21 is opened on one side of the bearing ring storage cavity 4-2 opposite to the feeding guide groove 5; the two ends of the feeding guide groove 5 are open.
[0022] Specifically, in this embodiment, since the feeding guide 5 needs to move horizontally within the feeding box 4, and in order to prevent the bearing ring storage cavity 4-2 from interfering with its movement, an entry groove 4-21 is provided to facilitate its movement.
[0023] Furthermore, one end of the feed guide 6 is closed and the other end is open; the indexing mechanism is located at the open end of the feed guide 6; the indexing mechanism includes an indexing plate 12; the axial direction of the indexing plate 12 is consistent with the width direction of the feed guide 6.
[0024] Furthermore, a second motor 13 is provided on the outer side of the feed guide groove 6; the second motor 13 is connected to the indexing plate 12; and a number of bearing rings to be processed are arranged inside the feed guide groove 6.
[0025] Specifically, in this embodiment, the bearing ring to be processed is placed in the feed guide groove 6 in a rolling posture. After the previous workpiece is unloaded (rolling down from the unloading guide groove 5), the feed guide groove 6 rotates downward under the drive of the rotating mechanism, so that its end is between the two clamping heads. At this time, the indexing plate 12 rotates. Since the indexing plate 12 has multiple indexing slots, when the feed guide groove 6 rotates downward and tilts, the workpiece will roll into one of the indexing slots. Then the indexing plate 12 rotates, which will cause the workpiece in that indexing slot to rotate and come between the two clamping heads to be clamped. When the above-mentioned indexing slot completely leaves the feed guide groove 6, the next indexing slot completely enters the feed guide groove 6, and the next workpiece to be processed will be in place, and so on.
[0026] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
