Description

Technical Field

[0001] This utility model relates to the field of CNC lathe feeding technology, specifically a feeding and finishing mechanism for CNC lathes. Background Technology

[0002] CNC lathes are among the most widely used CNC machine tools. Equipped with multi-station turrets or power turrets, they are high-precision, high-efficiency automated machine tools with a wide range of machining capabilities. They are mainly used for cutting the inner and outer cylindrical surfaces, inner and outer conical surfaces with arbitrary cone angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads of shaft or disc parts. They can also perform grooving, drilling, reaming, boring, and other machining operations.

[0003] An investigation revealed that a Chinese utility model patent discloses an automatic feeding CNC lathe (publication number: CN215659210U), which includes a worktable, a chamber, a conveyor roller, a support rod, and a sliding device. The chamber is located at the top center of the worktable. The conveyor roller is rotatably connected between the upper front and rear sides of the inner wall of the chamber. The support rod is fixedly connected to the left and right sides of the front and rear side walls of the worktable. The sliding device is fixedly connected to the top left side of the worktable. A motor is fixedly connected to the bottom left front side of the inner wall of the chamber. A telescopic rod is fixedly connected to the top center of the support rod.

[0004] In the aforementioned patent, the material to be processed placed inside the placement frame can reach the worktable through the sliding chute. When the conveying rollers on the worktable rotate, they can drive the material to move, thus realizing the material conveying. However, when conveying plate-shaped materials, since the plate-shaped material at the bottom of the plate stack bears the entire weight of the plate-shaped material above, the bottom plate-shaped material may get stuck inside the placement frame and have difficulty reaching the worktable through the sliding chute, thereby affecting the processing efficiency of the CNC machine tool.

[0005] Therefore, this utility model provides a feeding and finishing mechanism for CNC lathes to solve the above problems. Utility Model Content

[0010] The conveying mechanism includes a support plate, one side of which slides against the side of the placement frame. A rotating shaft is rotatably connected to the support plate, and a roller is fixedly connected to the side surface of the rotating shaft.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides a feeding and finishing mechanism for CNC lathes, such as... Figure 1 , Figure 2 and Figure 4 As shown, it includes a base plate 1, a placement frame 2 fixedly connected to the top of the base plate 1, a conveyor table 3 fixedly connected to the top of the base plate 1, a number of plates 19 are arranged inside the placement frame 2, a conveying mechanism for conveying the plates 19 is provided on the placement frame 2, and a lifting mechanism for lifting the plates 19 is provided on the top of the base plate 1.

[0026] The conveying mechanism includes a support plate 12, one side of which slides against the side of the placement frame 2. A rotating shaft 14 is rotatably connected to the support plate 12. A roller 15 is fixedly connected to the side surface of the rotating shaft 14. A rubber sleeve 16 is fitted on the side surface of the roller 15. Several evenly distributed grooves are formed on the rubber sleeve 16.

[0027] A limiting block 17 is fixedly connected to the side of the placement frame 2 near the support plate 12. A limiting groove 18 is opened on the support plate 12. The limiting block 17 is inserted into the inside of the limiting groove 18. A second electric push rod 11 is fixedly connected to the top of the base plate 1. The movable end of the second electric push rod 11 is fixedly connected to the bottom of the support plate 12.

[0028] The rotating shaft 14 passes through the support plate 12. A mounting bracket is fixedly connected to the side of the support plate 12 away from the placement frame 2. A motor 13 is fixedly connected to the mounting bracket. The output end of the motor 13 is fixedly connected to one end of the rotating shaft 14.

[0029] When using this equipment, the operator needs to place the plate 19 into the placement frame 2. Then, by controlling the second electric push rod 11, the movable end of the second electric push rod 11 drives the support plate 12 to move. When the support plate 12 moves, it can drive the rotating shaft 14, the roller 15, and the rubber sleeve 16 to move synchronously, thereby changing the distance between the rubber sleeve 16 and the top of the placement frame 2. The setting of the limit block 17 improves the stability of the support plate 12 when it moves. When the rubber sleeve 16 on the roller 15 comes into contact with the top of the plate 19, the motor 13 can be started. After the motor 13 drives the roller 15 to rotate through the rotating shaft 14, the friction between the rubber sleeve 16 and the plate 19 can make the plate 19 move out of the interior of the placement frame 2. Through the several grooves opened on the rubber sleeve 16, the friction between the rubber sleeve 16 and the plate 19 can be further improved to realize the feeding of the plate 19.

[0030] In order to ensure that all the plates 19 in the placement frame 2 can be conveyed out, such as Figure 1 , Figure 2 and Figure 3 As shown, the lifting mechanism includes a bracket 4, the bottom end of which is fixedly connected to the top of the base plate 1, the top end of which is fixedly connected to a connecting plate 5, the bottom of which is fixedly connected to a first electric push rod 6, the movable end of which is fixedly connected to a traction block 7, and a tray 8 is provided inside the placement frame 2.

[0031] The top of the tray 8 fits against the bottom of the plate 19, and one side of the traction block 7 extends into the interior of the placement frame 2 and is fixedly connected to one side of the tray 8.

[0032] The bracket 4 and connecting plate 5 provide a stable guarantee when the first electric push rod 6 is working. After all the plates 19 are placed on the tray 8 in the placement frame 2, the first electric push rod 6 is controlled so that its movable end drives the traction block 7 to move vertically. The traction block 7 can drive the tray 8 to move vertically. When the tray 8 moves, it can lift the plates 19 until the top plate 19 comes into contact with the rubber sleeve 16. At this time, the control of the first electric push rod 6 can be paused. After the top plate 19 is transported to the conveyor table 3 by the rotating roller 15 and the rubber sleeve 16, the first electric push rod 6 can be controlled again so that the next plate 19 comes into contact with the rubber sleeve 16. Then the above steps are repeated until all the plates 19 are removed from the inside of the placement frame 2. Then the first electric push rod 6 can be controlled so that its movable end moves to the bottom of the placement frame 2 with the tray 8 through the traction block 7 so that the staff can add the next batch of plates 19 into the placement frame 2.

[0033] Furthermore, to facilitate the placement of board 19 by staff, such as... Figure 1 , Figure 2 and Figure 4 As shown, an arc-shaped plate 9 and a limiting plate 10 are fixedly connected inside the placement frame 2, and a conveyor belt is provided on the conveyor table 3. The top of the placement frame 2 is flush with the top of the conveyor belt.

[0034] The curved surface of the curved plate 9 provides space for the plate 19 so that the staff can place the plate 19 into the placement frame 2. The limiting plate 10 is in contact with the support plate 8, which can improve the flatness of the plate 19 in the vertical direction inside the placement frame 2. After the plate 19 leaves the placement frame 2, it will come directly to the conveyor belt, which will transport the plate 19 to the CNC machine tool.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
