Description

Technical Field

[0001] This utility model relates to the field of bar stock conveying technology, and in particular to a bar stock conveying system for composite heavy cutting CNC lathes. Background Technology

[0002] CNC lathe is short for numerical control lathe. It is an automated lathe equipped with a program control system. This control system can logically process programs with control codes or other symbolic instructions, decode them, represent them with coded numbers, input them to the CNC device through an information carrier, and after calculation and processing, the CNC device sends out various control signals to control the lathe's movements and automatically process the parts according to the shape and size required by the drawings.

[0003] For example, the Chinese utility model patent with publication number CN220445850U can guide the placement hopper to move as a whole through guide sleeves and guide rails, which can push the bar stock on the feeding rack to the chuck for clamping. However, since the feeding rack is fixed and cannot be deflected, the feeding rack itself will block the processing after the bar stock is fed. Moreover, the feeding rack can only align the bar stock with the spindle and cannot actively insert the bar stock into the fixed clamp of the spindle. It still requires manual control, which has certain shortcomings. In view of this, we propose a composite heavy cutting CNC lathe bar stock feeding system. Utility Model Content

[0004] The purpose of this invention is to provide a composite heavy-duty CNC lathe bar stock conveying system to solve the problems mentioned in the background art.

[0017] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a composite heavy-duty cutting CNC lathe bar stock conveying system, including a machine tool body 1. A conveyor frame 2 is slidably connected to the left side surface of the machine tool body 1. Two guide plates 3 are fixedly connected to the right side surface of the conveyor frame 2. A feeding frame 4 is rotatably connected between the two guide plates 3. The rotatable feeding frame 4 can rotate to make room after the bar stock is fixed, so as to avoid affecting the spindle operation. A clearance groove 5 extending to its lower side surface is opened on the upper side surface of the feeding frame 4. The left side of the clearance groove 5 extends to the left side surface of the feeding frame 4. Mounting plates 6 are fixedly connected to the lower side surfaces of the two guide plates 3. A rotating hub is rotatably connected between the two mounting plates 6. A take-up roller 8 is fixedly sleeved on the outer surface of the rotating shaft 7. An intermittent feeding plate 9 is set between the two guide plates 3. A cable 10 is fixedly connected to the lower surface of the intermittent feeding plate 9. The cable 10 can drive the rotating shaft 7 to move synchronously when the intermittent feeding plate 9 moves, thereby cooperating with the automatic clearance component to realize the synchronous movement of the feeding rack 4. The end of the cable 10 is fixed to the outer surface of the take-up roller 8. An automatic clearance component is set on the rotating shaft 7, which can drive the feeding rack 4 to swing by means of the cable 10 and the movement of the intermittent feeding plate 9, so that it can rotate downward to complete the clearance after the bar is fixed, and avoid the presence of the feeding rack 4 from affecting the operation of the main shaft.

[0019] Furthermore, the automatic yielding component includes a rotating disk 11, which is fixedly sleeved on the outer surface of the rotating shaft 7. An extension rod 12 is fixedly connected to the outer surface of the rotating disk 11, and a roller 13 is provided at the end of the extension rod 12. The roller 13 and the extension rod 12 can not only synchronously control the feeding rack 4, but also reduce the friction between the roller 13 and the feeding rack 4 by means of the rotation of the roller 13. The outer surface of the roller 13 contacts the lower surface of the feeding rack 4. A torsion spring is fixedly connected between the rotating disk 11 and the mounting plate 6. The torsion spring can wind up the cable 10 when the intermittent feeding plate 9 descends. A sliding groove 14 extending to its lower surface is opened on the upper surface of the feeding rack 4. A guide rod 15 is fixedly connected to the inner wall of the sliding groove 14. A displacement plate 16 is slidably sleeved on the outer surface of the guide rod 15. A push plate 1 is fixedly connected to the upper surface of the displacement plate 16. 7. The push plate 17 can automatically push the bar stock into the fixed clamp of the main shaft, reducing manual operation. The lower surface of the feeding rack 4 is fixedly connected to an electric telescopic rod 18. The output end of the electric telescopic rod 18 is fixedly connected to the displacement plate 16. The upper surface of the two guide plates 3 is fixedly connected to side plates 19. The two guide plates 3 are fixedly connected to U-shaped limit plates 20. The U-shaped limit plates 20 ensure that the bar stock can only pass through one at a time, avoiding blockage and jamming. The guide plate 3 is equipped with an intermittent feeding component 21, which is connected to the intermittent feeding plate 9. Through the cooperation of the electric telescopic rod 18, the displacement plate 16, and the push plate 17, the bar stock can be pushed, so that the bar stock can be automatically pushed into the fixed clamp of the main shaft after alignment, without manual pushing, reducing workload. At the same time, the roller 13 can avoid the problem of high wear when pushing the feeding rack 4.

[0020] Among them, the intermittent feeding component 21, the conveyor frame 2, the intermittent feeding plate 9 and the guide plate 3 are all existing mechanisms. For details, please refer to the patent publication number CN220445850U. Since they are not the main structures, they will not be described in detail.

[0021] Working principle: During feeding, the bar stock is guided by the guide plate 3 and limited by the side plate 19 to the intermittent feeding plate 9. Simultaneously, the U-shaped limiting plate 20 ensures that only one bar stock can pass through at a time. Then, the intermittent feeding assembly 21 drives the intermittent feeding plate 9 to perform circular motion. When the intermittent feeding plate 9 rises, it synchronously pulls the cable 10. The cable 10, when pulled, drives the take-up roller 8 and the rotating shaft 7 to rotate. The rotation of the rotating shaft 7 synchronously drives the rotating disk 11 to rotate. After the rotating disk 11 rotates, it is aided by… The extension rod 12 and roller 13 push the feeding rack 4 to rotate. When the intermittent feeding plate 9 descends, the bar stock is blocked by the feeding rack 4 because its length exceeds the intermittent feeding plate 9. The bar stock is then placed above the feeding rack 4. The movement is repeated, causing the feeding rack 4 to swing until it is aligned with the axis of the machine tool again. At this time, the electric telescopic rod 18 drives the displacement plate 16 to move. After the displacement plate 16 moves, it drives the push plate 17 to move synchronously. Then, the push plate 17 drives the bar stock into the spindle fixing clamp to complete the automatic feeding.

[0022] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
