Description

Technical Field

[0001] This utility model relates to the field of material feeding technology, specifically an automatic material feeding mechanism for a CNC lathe. Background Technology

[0002] With the continuous development and progress of science and technology, automated production has become the mainstream of industrial production. CNC lathes are the most common type of automated production equipment. They are mainly used for cutting and machining the inner and outer cylindrical surfaces, inner and outer conical surfaces with arbitrary cone angles, complex rotating inner and outer curved surfaces, and cylindrical threads of shaft or disc parts. However, in current production lines, workpieces are manually loaded onto CNC lathes. Manual clamping is cumbersome, inefficient, and difficult to guarantee accuracy, which is not conducive to production.

[0003] According to Chinese Patent Publication No. CN214023509U, an automatic feeding mechanism for a CNC lathe is disclosed. This mechanism includes a workpiece feeding device for storing and outputting workpieces, a staggered feeding device for transferring workpieces from the workpiece feeding device to the blowing channel of a blowing seat, allowing the workpieces to slide into the blowing channel, a blowing seat, a feeding air pipe connecting the blowing seat and a pushing clamping device, a blowing device for blowing workpieces located in the blowing channel to the pushing clamping device, a pushing clamping device for pushing out workpieces conveyed by the feeding air pipe for clamping, and a mechanism for driving... The lifting drive device of the material feeding and clamping device has coordinated actions of various mechanisms, which can automatically transport the workpiece to the CNC lathe for cutting, realizing automated material feeding operation for the CNC lathe. It has a high degree of automation, improves work efficiency, and can meet the needs of large-scale production of enterprises. However, in this technical solution, it is inconvenient for personnel to adjust the feeding height of the workpiece feeding device after installation and use. When feeding CNC lathes of different heights, it is necessary to use first mounting brackets of different heights to support the workpiece feeding device, which makes it inconvenient to use and has low flexibility. Therefore, we propose an automatic feeding mechanism for CNC lathes. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figure 1-5 As shown, this utility model provides a technical solution: an automatic feeding mechanism for a CNC lathe, including a workpiece feeding device 2 installed on a placement table 1. The bottom end of the workpiece feeding device 2 is rotatably connected to a base plate 3. Limiting openings 7 are opened on the base plate 3 near both sides. Support frames 4 are movably passed through the limiting openings 7. Screw 1 5 and screw 2 11 are movably passed through the base plate 3 near both sides, and screw 1 5 and screw 2 11 are rotatably connected to the base plate 3 through bearings. The two support frames 4 are threaded onto the outer walls of screw 1 5 and screw 2 11, respectively. A rotating plate 6 is fixedly installed at the top of screw 1 5. A support plate 12 is fixedly installed at the bottom end of the support frame 4. A support pad 15 and a positioning post 13 are fixedly installed at the bottom end of the support plate 12. A positioning hole 14 is opened on the placement table 1. The positioning post 13 movably passes through the positioning hole 14, and the support pad 15 is tightly fitted to the top surface of the placement table 1. Screw 1 5 and screw 2 11 are connected by a transmission at their bottom ends.

[0024] Synchronous pulley 8 is fixedly installed at the bottom end of screw 11, and synchronous pulley 10 is fixedly installed at the bottom end of screw 21. Synchronous belt 9 is provided on the outer wall of synchronous pulley 8 and synchronous pulley 10.

[0025] Among them, the workpiece feeding device 2 is the disclosed technology in the announcement number CN214023509U, entitled "An Automatic Feeding Mechanism for a CNC Lathe", so it is not described or drawn in detail in this article and in the accompanying drawings;

[0026] Specifically, in the above technical solution, when the automatic feeding mechanism of the CNC lathe is in use, the workpiece feeding device 2 is installed on the placement table 1, with the positioning pin 13 passing through the positioning hole 14. Then, the rotating plate 6 can be rotated, which drives the screw 5 to rotate. The screw 5 drives the synchronous pulley 8 to rotate, and the synchronous pulley 8 drives the synchronous pulley 10 to rotate via the synchronous belt 9. The synchronous pulley 10 drives the screw 11 to rotate. The screw 5 and the screw 11 respectively drive the support frame 4 on them to move downward, causing the base plate 3 to move upward. This causes the base plate 3 to drive the workpiece feeding device 2 to move upward, increasing the height of the workpiece feeding device 2. Through the above structure, it is convenient for personnel to adjust the workpiece feeding device. The feeding height of the workpiece feeding device 2 is adjusted to accommodate CNC lathes of different heights, greatly reducing the limitations of the device. This solves the problem in existing technologies where the feeding height of the workpiece feeding device 2 is difficult to adjust after installation, and different height mounting brackets are required to support the workpiece feeding device 2 when feeding CNC lathes of different heights, resulting in inconvenience and low flexibility. By setting the support pad 15, the workpiece feeding device 2 can be provided with a certain degree of shock absorption. Furthermore, by setting the positioning column 13 and positioning hole 14, the workpiece feeding device 2 can be limited on the placement table 1, greatly improving the stability of the workpiece feeding device 2.

[0027] Furthermore, a baffle is fixedly installed at the top of screw 21;

[0028] By setting a baffle, the support frame 4 can be limited to prevent it from detaching from the screw rod 11.

[0029] Furthermore, the support pad 15 is made of wear-resistant rubber;

[0030] Among them, by setting the support pad 15, the workpiece feeding device 2 can play a certain role in shock absorption.

[0031] Furthermore, a T-shaped ring plate 16 is fixedly installed at the bottom of the workpiece feeding device 2, and a T-shaped ring groove 17 is opened at the top of the bottom plate 3. The T-shaped ring plate 16 and the T-shaped ring groove 17 are rotatably connected.

[0032] Among them, by setting the T-shaped ring plate 16 with the T-shaped ring groove 17, the workpiece feeding device 2 can be limited, so that the workpiece feeding device 2 can be fixed and rotated on the placement table 1.

[0033] Furthermore, a fixed frame 19 is fixedly installed on the outer wall of the workpiece feeding device 2, and a magnetic seat 20 is fixedly embedded in the fixed frame 19. An adsorption ring plate 18 is fixedly installed on the top of the base plate 3. The magnetic seat 20 is magnetically connected to the adsorption ring plate 18. The material of the adsorption ring plate 18 is iron.

[0034] When it is necessary to adjust the feeding direction of the workpiece feeding device 2, the magnetic base 20 can be turned off, and then the workpiece feeding device 2 can be rotated directly on the base plate 3 to adjust its feeding direction. After the adjustment is completed, the magnetic base 20 is turned on so that the magnetic base 20 is attracted to the adsorption plate, thereby fixing the workpiece feeding device 2. Through the above structure, it is convenient for personnel to adjust the feeding direction of the workpiece feeding device 2, further reducing the limitations of the use of the workpiece feeding device 2. The structure is simple and highly practical.

[0035] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
