Description
Technical Field
[0001] The utility model relates to the technical field of numerically controlled lathes, in particular to an ejector pin structure of a high-speed numerically controlled lathe. Background Art
[0002] High-speed CNC lathes are computer-controlled to complete various complex processing operations. They are mainly composed of machine body, spindle, workbench, turret, tool and control system. They automatically track and detect programmed machine tools through programming, interpolation and other methods, and adjust the machine tools according to the detection results, so that the technology has the characteristics of high precision, high efficiency, multi-function, programmability, strong flexibility, simple operation and high reliability. The processing process of high-speed CNC lathes has been digitized, automated and programmed, which greatly improves production efficiency.
[0003] The structure of the existing control lathe ejector mainly includes a clamping part, a rod part and a positioning part. The clamping part is the key part of the ejector, which is responsible for fixing the workpiece and ensuring its stability during the processing. The rod part is usually cylindrical, which is a bridge connecting the clamping part and the positioning part, and bears various forces during the processing. The positioning part is located at the connection between the clamping part and the rod part. Its function is to ensure that the workpiece can be accurately aligned with the processing position to ensure the processing accuracy. For example, the announcement number is CN218192602U, and the name is: A Chinese patent for a high-speed CNC lathe ejector pin structure. Through the cooperation between the handle, the ejector pin, the heat dissipation assembly and the oil filling hole, the operator can inject an appropriate amount of lubricating oil through the oil filling hole into the connection between the inside of the handle and its internal bearing, so as to facilitate the smooth rotation of the ejector pin during subsequent use. However, long-term use may cause wear of the ejector pin. Therefore, the operator should regularly check the wear of the ejector pin. Once severe wear is found, it is necessary to replace it with a new ejector pin in time to ensure processing quality and safety. The integrated ejector pin structure will not be able to replace the worn points of the ejector pin, and it needs to be replaced as a whole, which causes a certain amount of waste. Therefore, the present application provides a high-speed CNC lathe ejector pin structure to meet the needs. Utility Model Content

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.
[0028] Combine the following Figure 1-5 The embodiment shown describes the technical solution of the utility model:
[0029] The utility model comprises an ejector body 1 and a mounting column 2 fixedly connected to the inside of the ejector body 1, an ejector head 14 is arranged on the top of the mounting column 2, a partition plate 3 is fixedly connected to the peripheral side of the mounting column 2, and the partition plate 3 divides the ejector body 1 into an independent upper cavity 4 and a lower cavity 5, a plurality of connecting holes 6 are provided on the top of the partition plate 3, and the connecting holes 6 are used to connect the upper cavity 4 with the lower cavity 5, a control valve body is arranged inside the connecting holes 6, an operating port 19 is provided on the side wall of the ejector body 1, and the operating port 19 is connected to the upper cavity 4, an operating sealing plate 21 is rotatably connected inside the operating port 19, and the operating sealing plate 21 is used to seal the operating port 19.
[0030] During use, the ejector body 1 can be directly connected to the CNC lathe for effective use. When the top ejector head 14 is worn, the control valve body can be effectively controlled by an external controller to be in an open state, so that the lubricating oil in the upper cavity 4 can enter the lower cavity 5 through the connecting hole 6 and the control valve body to ensure the dryness of the upper cavity 4. The operating sealing plate 21 can be pulled to rotate under force, so that the operating port 19 is exposed. At this time, the operator can disassemble the ejector head 14 on the top of the mounting column 2 through the operating port 19, thereby achieving the effect of independently replacing or maintaining the ejector head 14, thereby improving the convenience of daily maintenance and reducing the maintenance cost.
[0031] A clamping cavity 10 is provided inside the mounting column 2 , and the bottom of the ejector head 14 is connected to two clamping members 11 via an elastic plate 13 , and the bottom of the clamping members 11 is inserted and clamped in the clamping cavity 10 .
[0032] During its use, the ejector head 14 can be effectively fixed directly through the engaging structure of the engaging cavity 10 and the engaging member 11, so that it can be more stable during use. At the same time, during its use, the extrusion portion 15 can be directly pressed to make the extrusion portion 15 deformed by force, thereby driving the engaging member 11 to move. When the two engaging members 11 are close to each other, the engaging limit structure can be released, and the ejector head 14 can be directly pulled, and the ejector head 14 can be pulled out and disassembled, thereby achieving the purpose of maintenance and replacement.
[0033] Two elastic members 12 are fixedly connected to one side of the two engaging members 11 that are close to each other, and a pressing portion 15 is provided at the bottom of the elastic plate body 13 . The pressing portion 15 is in a triangular structure.
[0034] The opening of the extrusion portion 15 can effectively increase the control effect during the adjustment of the elastic plate body 13, so that the movement space of the locking member 11 driven by deformation can be effectively increased, thereby simplifying its disassembly and assembly steps. At the same time, when cooperating with the elastic member 12, the elastic member 12 can effectively control the locking member 11 during use, so that it can better fit with the locking cavity 10, thereby ensuring the stability of the locking structure.
[0035] The top of the engaging cavity 10 passes through the top of the mounting column 2 , and a sealing ring 17 is fixedly connected to the engaging cavity 10 , and a rubber plate 16 is fixedly connected between the two engaging members 11 .
[0036] During its use, the sealing ring 17 can directly seal the gap between the engaging cavity 10 and the engaging member 11 to avoid the possibility of lubricating oil leaking along the gap, thereby improving the overall cleanliness of use to a certain extent.
[0037] The interior of the ejector body 1 is connected to a same lower pressing plate 8 via a plurality of electric push rods 7 , and the lower pressing plate 8 is lifted and lowered inside the upper cavity 4 , and a scraper is fixedly sleeved on the circumference of the lower pressing plate 8 .
[0038] Before maintenance, the lower pressure plate 8 can be directly controlled autonomously through an external controller, so that the lower pressure plate 8 falls along the upper cavity 4 under the action of the electric push rod 7. At this time, the falling lower pressure plate 8 will better drive the lubricating oil under the action of its own scraper, so that it will connect to the hole body 6 and enter the internal storage of the lower cavity 5, thereby avoiding the possibility of lubricating oil leakage when the user disassembles the ejector head 14, thereby improving the overall stability.
[0039] The bottom of the electric push rod 7 is fixedly connected with a sponge body 9 , and the oil filling pipe 18 fixedly connected to the top of the ejector body 1 can penetrate the top and bottom of the lower pressing plate 8 and be connected with the sponge body 9 .
[0040] During its use, the user can directly guide the lubricating oil into the interior of the sponge 9 through the oil filling pipe 18. At this time, the sponge 9 can absorb the lubricating oil and effectively apply and install the column 2 and the ejector head 14 during its use, thereby ensuring the stability of the overall ejector structure during use.
[0041] The bottom of the lower pressing plate 8 is fixedly connected with a magnetic attraction member 24 , and the top of the partition plate body 3 is fixedly connected with a magnetic attraction plate 23 via a baffle plate 22 , and the magnetic attraction plate 23 and the magnetic attraction member 24 are adapted to each other.
[0042] When the ejection head 14 is disassembled, the electric push rod 7 can effectively drive the sponge body 9 to fall through the lower pressure plate 8, so that the sponge body 9 can be located inside the circular ring structure with the top opening formed by the partition plate body 3 and the baffle plate 22, thereby allowing the lubricating oil inside the sponge body 9 to fall through the connecting hole body 6 at the bottom of the partition plate body 3. At the same time, when the lower pressure plate 8 falls to the maximum position, the magnetic suction plate 23 and the magnetic suction part 24 are in contact, so that the position of the lower pressure plate 8 can be limited, making it more stable during use.
[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
