Description

Technical Field

[0001] This utility model relates to the field of CNC machining equipment technology, and in particular to a CNC machining equipment for a POGOPIN needle and its tube. Background Technology

[0002] A POGOPIN is a spring-loaded probe formed by riveting three basic components: a plunger, a tube, and a spring using high-precision equipment. Traditional processing methods cannot meet the high precision requirements of POGOPIN plungers and tubes. CNC machining equipment, with its high degree of automation, precise control capabilities, and stable processing quality, has become the key to producing high-quality POGOPIN components. Among them, CNC Swiss-type lathes are more commonly used.

[0003] Because POGOPINs require extremely high dimensional accuracy—for example, the diameter of the needle tip, and the inner and outer diameters of the needle tube must be within very small tolerances—CNC Swiss-type machining centers can achieve micron-level dimensional accuracy control through precise control systems and high-resolution encoders, ensuring that the produced POGOPIN parts meet stringent design requirements. However, current CNC Swiss-type machining processes generate a significant amount of internal debris, often requiring frequent machine stops for cleaning, which is detrimental to processing efficiency.

[0004] To address the aforementioned problems, this utility model document proposes a POGOPIN needle and its needle tube CNC machining equipment. Utility Model Content

[0005] This invention provides a POGOPIN needle and its needle tube CNC machining equipment, which solves the problem that the existing technology has the disadvantage of generating a lot of internal debris during the CNC Swiss-type machine processing, which often requires workers to stop the machine frequently for cleaning, which is not conducive to ensuring processing efficiency.

[0006] This utility model provides the following technical solution:

[0007] A POGOPIN needle and its needle tube CNC machining equipment, comprising:

[0008] The CNC Swiss-type lathe body has a U-shaped water receiving trough inside its machining chamber. The U-shaped water receiving trough is inclined downward through two vertical plates at the bottom. A rectangular drain pipe is connected to the lower part of the U-shaped water receiving trough. The other end of the rectangular drain pipe passes through the outer wall of the machining chamber of the CNC Swiss-type lathe body and extends downward.

[0009] The circulating flushing component is located outside the body of the CNC Swiss-type lathe and is used to flush out the debris in the machining chamber.

[0010] The filter assembly, located on the outer wall of the CNC Swiss-type lathe, is used to filter debris discharged along with the water flow.

[0011] In one possible design, the circulating flushing assembly includes an annular water sprayer fixedly installed on the top of the inner wall of the machining chamber of the CNC Swiss-type lathe. The bottom of the annular water sprayer is provided with multiple nozzles. The CNC Swiss-type lathe is externally provided with a water tank and a water pump. The input end of the water pump is connected to the inner wall of the water tank through a first water pipe, and the output end of the water pump is connected to the input end of the annular water sprayer through a second water pipe.

[0012] In one possible design, the top of the water tank is not closed, and the water tank is located below the outlet of the rectangular drain pipe.

[0013] In one possible design, the filtration assembly includes a filter disc disposed on the outer wall of the base of the CNC Swiss-type lathe, the filter disc being located between a rectangular drain pipe and a water storage tank, and a replaceable filter screen being disposed at the bottom of the filter disc.

[0014] In one possible design, two L-shaped locking blocks are symmetrically fixed on the outer wall of the filter disc to facilitate its disassembly and installation, and two fixing blocks are symmetrically fixed on the outer wall of the CNC Swiss-type machine body base, with insertion holes for engaging the corresponding L-shaped locking blocks on the fixing blocks.

[0015] In one possible design, the four corners of the bottom of the CNC Swiss-type lathe body are all fixedly equipped with casters for easy relocation.

[0016] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0017] The working principle and usage process of this technical solution are as follows:

[0018] After starting the CNC Swiss-type lathe, it begins processing the POGOPIN needle and its tube according to the preset program. During the processing, the cutting tools inside the CNC Swiss-type lathe will generate chips. These chips will be washed away by the coolant and fall into the U-shaped water collection tank. After starting the water pump, the water pump draws water from the water tank and delivers the water to the annular water sprayer through the first water pipe. Multiple nozzles at the bottom of the annular water sprayer spray water evenly into the processing chamber, washing away the chips attached to the workpiece and the machine tool. The washed water and chips flow together into the U-shaped water collection tank and then are discharged through the rectangular drain pipe. When the discharged water and chips pass through the filter plate, the filter screen will intercept the chips, while the clean water continues to flow into the water tank, realizing the recycling of coolant. When the filter screen is clogged or needs to be cleaned, the filter screen can be removed from the CNC Swiss-type lathe by disassembling the L-shaped clamp, and then reinstalled after replacing or cleaning the filter screen.

[0019] This utility model has the following beneficial effects:

[0020] This invention, by setting up a circulating flushing component and a filtering component, realizes the automatic cleaning of debris inside the CNC Swiss-type lathe body and the circulating filtration and utilization of coolant, reducing the time for workers to frequently stop the machine for cleaning, significantly improving processing efficiency, and avoiding the impact of debris on processing accuracy and surface quality, thus ensuring the processing quality of POGOPIN needles and their tubes.

[0021] This invention makes equipment maintenance and cleaning simpler and more convenient through the design of replaceable filter screens and easy filter disc disassembly and installation. Attached Figure Description

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0030] Example 1

[0031] Please refer to Figure 1-4 A CNC machining equipment, comprising:

[0032] The CNC Swiss-type lathe body 1, model B0205-III, is the main structure of the entire equipment and is used for precision machining of POGOPIN needles and their tubes. A U-shaped water collection trough 3 is installed in the machining chamber of the CNC Swiss-type lathe body 1. The design of the U-shaped water collection trough 3 can effectively collect the coolant and debris generated during the machining process. In order to more effectively discharge the debris and coolant, the U-shaped water collection trough 3 is inclined downward through two vertical plates 4 at its bottom. This design can ensure that the debris and coolant can flow smoothly into the lower part of the U-shaped water collection trough 3. A rectangular drain pipe 5 is connected to the lower part of the U-shaped water collection trough 3. The other end of the rectangular drain pipe 5 penetrates the outer wall of the machining chamber of the CNC Swiss-type lathe body 1 and extends downward to facilitate the discharge of debris and coolant to the outside of the equipment.

[0033] To flush out debris from the machining chamber, a circulating flushing assembly is provided. The circulating flushing assembly mainly includes an annular water sprayer 13 fixedly installed on the top of the inner wall of the machining chamber of the CNC Swiss-type machine body 1. The bottom of the annular water sprayer 13 is provided with multiple nozzles 14 to ensure that the flushing liquid can evenly cover the entire machining chamber. The CNC Swiss-type machine body 1 is provided with a water tank 10 and a water pump 11. The input end of the water pump 11 is connected to the inner wall of the water tank 10 through a first water pipe 12, while the output end of the water pump 11 is connected to the input end of the annular water sprayer 13 through a second water pipe 15. In this way, when the water pump 11 is started, the water in the water tank 10 will be pumped to the annular water sprayer 13 and sprayed out through the nozzles 14, thereby flushing the debris in the machining chamber.

[0034] The top of the water tank 10 is not closed, which allows users to easily add water to the water tank 10 at any time. In addition, the water tank 10 is located below the outlet of the rectangular drain pipe 5 to ensure that the coolant and debris discharged from the rectangular drain pipe 5 can fall directly into the water tank 10, thereby realizing the recycling of coolant.

[0035] To filter out debris discharged along with the water flow, a filter assembly is also provided. The filter assembly mainly includes a filter disc 6 set on the outer wall of the base of the CNC Swiss-type machine body 1. The filter disc 6 is located between the rectangular drain pipe 5 and the water storage tank 10. A replaceable filter screen is provided at the bottom of the filter disc 6 so that the user can clean the debris on the filter screen at any time. In this way, when the coolant and debris are discharged from the rectangular drain pipe 5, they will first pass through the filter screen of the filter disc 6. The debris will be intercepted by the filter screen, while the coolant will continue to flow into the water storage tank 10.

[0036] To facilitate the disassembly and installation of the filter disc 6, two L-shaped locking blocks 8 are symmetrically fixed on the outer wall of the filter disc 6. Correspondingly, two fixing blocks 7 are symmetrically fixed on the outer wall of the base of the CNC Swiss-type machine body 1. Each fixing block 7 is provided with a socket 9 for engaging the corresponding L-shaped locking block 8. When the filter disc 6 needs to be disassembled, the user only needs to pull the L-shaped locking block 8 out of the socket 9; and when the filter disc 6 needs to be installed, the user only needs to insert the L-shaped locking block 8 into the corresponding socket 9.

[0037] This application can be used for the production of POGOPIN needles and their vials, and can also be used in other fields applicable to this application.

[0041] Please refer to Figure 2 To facilitate the relocation of the equipment, casters 2 are fixedly installed at the four corners of the bottom of the CNC Swiss-type machine body 1, so that users can move the entire equipment at any time as needed.

[0042] However, as is well known to those skilled in the art, the working principles and wiring methods of the CNC Swiss-type machine body 1 and the water pump 11 are commonplace and belong to conventional methods or common knowledge. They will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. In the absence of conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.
