[0001] This utility model relates to the field of machining technology, specifically to an automatic loading and unloading device for machining the inner annular groove of an annular nut. Background Technology

[0002] Currently, the machining of ring groove nuts is usually carried out using CNC lathes. However, due to the machining of internal holes, the production cycle of machining the workpiece using a CNC lathe is relatively long, resulting in low production efficiency.

[0003] There are two ways to load CNC lathes on the market: (1) manual loading, where workers manually clamp the workpiece into the CNC lathe. This method has low production efficiency and poses safety hazards, making it easy for accidents to occur; (2) robotic loading, where a robotic arm clamps the workpiece and then places it into the CNC lathe. However, robotic arms are expensive, which greatly reduces the company's profits. Furthermore, robotic arms are prone to errors and require multiple adjustments, which reduces production efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic loading and unloading device for machining the inner annular groove of an annular nut. By using an internally inserted push rod mounting block and a receiving plate, the lifting and lowering of the mounting block allows the receiving plate to support the workpiece and move the workpiece to the side of the fixture. Then, the push cylinder and push rod push the workpiece into the fixture, realizing automatic loading of the workpiece and improving production efficiency.

[0005] This utility model provides the following technical solution: an automatic loading and unloading device for machining the inner annular groove of a ring groove nut, comprising a hopper fixed on a machine tool cover and a lifting cylinder, characterized in that: a mounting block is connected to the telescopic end of the lifting cylinder, a receiving plate and a pushing cylinder are respectively fixed on both sides of the mounting block, the outlets of the lifting cylinder and the hopper are on the same axis, a pushing rod is connected to the telescopic end of the pushing cylinder, the pushing rod is inserted into the mounting block and extends from the other end of the mounting block, located at the upper end of the receiving plate, the workpieces in the hopper fall sequentially into the receiving plate, and the workpieces are pushed into the fixture by the telescopic movement of the pushing cylinder.

[0006] To achieve automatic sequential unloading of workpieces, a partition is formed inside the unloading hopper, which divides the chamber into an unloading compartment and a blocking compartment. Workpieces are stacked in the unloading compartment, and an unloading cylinder is fixed inside the blocking compartment. An unloading block is fixed to the telescopic end of the unloading cylinder. An unloading port is opened at the lower end of the unloading hopper, and there is an unloading gap between the partition and the unloading port. The thickness of the unloading block is greater than the height of the unloading gap. The unloading cylinder performs intermittent reciprocating motion to discharge the workpieces sequentially from the lower end of the partition.

[0007] To facilitate the installation of the cooling pipeline on the lathe, a support rod is connected to the other side of the pusher cylinder, and the support rod is used to wind the cooling pipeline.

[0008] In order to push out the machined workpiece, a spindle box is also included. A clamp is connected to the end of the output shaft of the spindle box. The output shaft is a hollow shaft, and a push rod is set at the center of the output shaft. The push rod is used to push out the workpiece.

[0009] In order to control the movement of the tool on the X and Y axes, a tool post slide box is fixed to the side of the spindle box, a cross tool post slide box slides on the upper end of the tool post slide box, a tool post is fixed on the cross tool post slide box, and a tool is fixed on the tool post.

Detailed Implementation

[0012] 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.

[0013] Please see Figure 1 This utility model provides a technical solution: an automatic loading and unloading device for machining the inner annular groove of a grooved nut, including a hopper 4 fixed on a machine tool housing 1 and a lifting cylinder 5. The hopper 4 is a cone shape with a larger top and a smaller bottom. A mounting block 6 is connected to the telescopic end of the lifting cylinder 5, and the lifting cylinder 5 controls the height of the mounting block 6. A receiving plate 64 and a pushing cylinder 61 are respectively fixed on both sides of the mounting block 6. The receiving plate 64 is an arc-shaped plate. The outlets of the lifting cylinder 5 and the hopper 4 are on the same axis. A pushing rod 63 is connected to the telescopic end of the pushing cylinder 61. The pushing rod 63 is inserted into the mounting block 6 and extends from the other end of the mounting block 6, located at the upper end of the receiving plate 64. 1 is used to push the workpiece received on the receiving plate 64 into the fixture 3. The workpieces in the unloading hopper 4 fall into the receiving plate 64 in sequence. The workpieces are pushed into the fixture 3 by the extension and retraction of the pushing cylinder 61. The height of the mounting block 6 is controlled by the lifting cylinder 5. First, the receiving plate 64 is moved to the lower end of the unloading hopper 4 to catch the workpiece. Then, the receiving plate 64 is moved to the side of the fixture 3. Then, the workpiece is pushed into the fixture 3 by the extension and retraction of the pushing cylinder 61 and locked by the fixture 3. Then, the lifting cylinder 5 and the pushing cylinder 61 are reset. The tool 82 is moved to the side of the workpiece for processing. After processing is completed, the push rod in the spindle box 2 will push out the processed workpiece, realizing automatic loading and unloading of workpieces.

[0014] like Figure 2 As shown, a partition 41 is formed inside the feeding hopper 4, dividing the chamber into a discharge compartment and a barrier compartment. Workpieces are stacked in the discharge compartment, and a feeding cylinder 42 is fixedly installed in the barrier compartment. A feeding stop block 43 is fixed to the telescopic end of the feeding cylinder 42. A discharge port 45 is opened at the lower end of the feeding hopper 4, and the feeding stop block 43 is located on the discharge port 45. There is a discharge gap 44 between the partition 41 and the discharge port 45. The thickness of the feeding stop block 43 is greater than the height of the discharge gap 44, allowing the workpiece to pass through smoothly. The material rolls out through the material gap 44 and is blocked by the material stop block 43, thus blocking the workpiece. The material cylinder 42 makes intermittent reciprocating motion. When the material stop block 43 moves upward and reduces the blocking area of ​​the material gap 44, the workpiece will be discharged from the material gap 44. When the material stop block 43 moves downward and blocks the material gap 44, the workpiece is blocked in the material hopper 4. The intermittent reciprocating motion of the material cylinder 42 causes the workpiece to be discharged from the lower end of the partition 41 in sequence.

[0015] The other side of the pusher cylinder 61 is connected to a support rod 62. The support rod 62 is used to wind the cooling pipe. The cooling pipe is wound on the support rod 62 to prevent the cooling pipe from being laid on the machine tool bed and affecting the movement of the tool post 81 or the cross tool post slide box 8.

[0016] It also includes a spindle box 2, with a clamp 3 connected to the end of the output shaft of the spindle box 2. The output shaft is a hollow shaft, and the output shaft controls the rotation of the clamp 3. A push rod is set at the center of the output shaft, which is used to push the workpiece out to realize automatic unloading of the workpiece.

[0017] A tool post slide box 7 is fixed to the side of the spindle box 2. A transverse tool post slide box 8 slides on the upper end of the tool post slide box 7. A tool post 81 is fixed on the transverse tool post slide box 8. A cutting tool 82 is fixed on the tool post 81.

[0018] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
