Description

Technical Field

[0001] This utility model relates to the field of bearing processing equipment technology, and in particular to a feeding and discharging conveying device for a bearing ultra-precision machine. Background Technology

[0002] Bearing ultra-precision machines are precision machining equipment used in the bearing manufacturing process. In order to improve production efficiency, modern ultra-precision machines are equipped with automated feeding and discharging devices to realize automatic feeding and unloading of bearings.

[0003] Existing feeding and discharging conveying devices mostly use conveyor belts in conjunction with fixed chutes or guide rails. This structure is stable when handling bearings of a single specification. However, in actual production, ultra-precision machines need to frequently switch to process bearings of different sizes and models. The fixed guide structure cannot automatically adapt to changes in the outer diameter of the bearing. As a result, when the bearing transitions from the conveyor belt to the subsequent workstation, it may experience positional shift or jamming due to mismatch in guide spacing, causing deviation and affecting the stability of the conveying and the compatibility of the equipment.

[0004] Furthermore, in order to achieve the connection between workstations, the bearings usually need to go through a gravity rolling or sliding stage during the conveying process, such as falling from the horizontal conveyor belt into the receiving hopper or arc frame. During this process, the bearings will impact the baffle of the receiving structure at high speed due to inertia. This rigid collision not only produces a harsh noise, but also causes minor impact damage to the bearing surface that is about to undergo ultra-precision machining. More importantly, the huge impact force will cause the bearing to rebound or become unstable in position within the receiving frame, resulting in inaccurate positioning. This makes it difficult for the subsequent gripping or lifting mechanism to operate accurately, thereby reducing the success rate and reliability of the automated process.

[0005] Therefore, this utility model proposes an infeed and outfeed conveying device for a bearing ultra-precision machine to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems existing in the feeding and discharging devices of bearing ultraprecision machines, such as the inability to automatically adapt to bearings of different sizes, easy deviation during conveying, large impact force when bearings roll off, inaccurate positioning, and damage, this utility model aims to provide a feeding and discharging device for bearing ultraprecision machines with an improved structure that can effectively solve the above problems.

[0029] Working principle: When in use, the bearing is first conveyed by the conveyor belt component 10. When it is conveyed to the right end, it falls into the inside of the guide slide table 4 under the action of gravity and inertia. At this time, the bearing rolls along the inclined sliding surface opened inside the guide slide table 4 into the groove of the arc frame 5. Then the drive motor 7 starts, and the output end of the drive motor 7 rotates to drive the torque limiting device 8. The torque limiting device 8 drives the lifting conveyor belt component 6 to start running. The conveyor plate 9, driven by the lifting conveyor belt component 6, carries the bearing out from the groove opened in the arc frame 5 and conveys it along the lifting conveyor belt component 6 to the inside of the processing tank 11 for processing. After processing, the bearing is conveyed out from the rear side of the inner wall of the processing tank 11. The torque limiting device 8 can prevent damage to the lifting conveyor belt component 6 when the material is jammed. When feeding and unloading bearings of different sizes is required, and it is necessary to ensure that the bearings can accurately and stably transition from conveyor belt component 10 to lifting conveyor belt component 6, the guiding mechanism 2 comes into play. The sensor 207 controls the synchronous extension and retraction of the telescopic rods 206 on the front and rear sides of the guide slide table 4 according to the size of the bearing. The movement of the telescopic rods 206 adjusts the distance between the two guide slide plates 202. At this time, the guide rod 201 plays a guiding role. After the adjustment is completed, when the bearing enters the guide slide table 4 from the conveyor belt component 10, it first passes through the dovetail guide slide plate 203. The dovetail guide slide plate 203 guides the bearing... The initial guiding function guides the bearing between the two guide plates 202. The buffer pad 204 acts as a buffer when the bearing is impacted, preventing damage to the bearing and reducing the noise generated by the bearing hitting the dovetail guide plate 203. When the bearing passes between the two guide plates 202, the two guide plates 202 provide precise guidance for the bearing. At the same time, when the bearing contacts the guide plate 202, the roller 205 rotates under the action of friction, reducing the conveying resistance and standardizing the path of the bearing from the conveyor belt component 10 to the lifting conveyor belt component 6, preventing the bearing from running off-track. Furthermore, when it is necessary to buffer the bearing entering the arc frame 5, the buffer mechanism 3 comes into play. When the bearing comes from the inclined guide surface of the guide slide table 4 to the inner wall of the arc frame 5, under the action of inertia, the bearing will slide to the upper right along the arc inner wall of the arc frame 5. At this time, the bearing hits the second buffer pad 305, the second buffer pad 305 deforms and buffers the bearing. This impact force is transmitted to the spring 304 along the second buffer pad 305. Under the action of this force, the spring 304 moves obliquely upward. At this time, the second buffer pad 305 squeezes the baffle 303, and at the same time, the sliding shaft 302 slides inward along the inner wall of the fixed plate 301. Under the action of the second buffer pad 305 and multiple sliding shafts 302, the buffering of the bearing from the conveyor belt component 10 is completed, so that the bearing is stably restricted to the inner wall of the arc frame 5, providing a guarantee for subsequent conveying.
