[0002] In the existing punching process of medical device tubes, the commonly used punching methods are mainly laser punching and drilling. However, the high heat generated by laser punching will cause edge melting, and the punching accuracy and quality cannot be guaranteed. The twist drill and other drilling methods used in traditional machining are prone to produce chips and are difficult to remove. Therefore, hollow drilling needles are generally used for punching.

[0003] The existing hollow drilling needles will have the following problems when drilling holes in pipes. The punching machine removes the waste in the drilling needle by blowing the waste out of the drilling needle with air flow, but the air flow used for blowing is small. If the waste is not blown out, it is easy to cause the drilling needle to be blocked, affecting the life of the drilling needle and the drilling quality. Utility Model Content

[0030] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0031] In the description of this application, it should be noted that the terms "inside", "outside", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the application is usually placed when in use, which is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0032] In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0033] See also Figure 1 , and combined with Figure 2-Figure 4 The drilling and ejecting tooling in the present application is mainly used in the drilling process of medical device pipes. Specifically, by setting the ejecting needle 3, after the drilling needle 2 drills and forms the pipe, the ejecting needle 3 ejects the waste material remaining in the drilling needle 2, so that the waste material can be completely separated from the drilling needle 2 and the pipe.

[0034] Through the above-mentioned material-pushing form, it is possible to prevent waste materials from re-adhering to the hole during the retraction of the drilling needle 2, thereby effectively ensuring the drilling quality. At the same time, the waste materials cut by the drill can be completely removed from the drilling needle 2 to avoid stagnation and clogging in the drilling needle 2. When the drilling needle 2 drills a hole again, the waste materials cut by the drill can reliably enter the emptied needle cavity, thereby extending the service life of the drilling needle 2.

[0035] The drilling and ejecting tooling in the utility model is installed on a drilling machine, which includes a drilling motor 1. A drilling needle 2 is installed on the output end of the drilling motor 1. The drilling and forming of the pipe is mainly carried out by driving the drilling needle 2 to rotate by the drilling motor 1.

[0036] After the drilling needle 2 drills a hole, the thick part of the pipe wall corresponding to the hole-forming part that is drilled and cut off constitutes drilling waste. If the waste is not removed in time, the waste will be detached from the drilling needle 2 and the pipe, which may easily cause the risk of the drilling needle 2 re-adhering to the hole-forming part when it is returned, affecting the drilling quality.

[0037] At the same time, because the drilling waste is completely and tightly fitted in the drilling needle 2, after a long period of drilling, the drilling waste is easily retained in the drilling needle 2, resulting in more and more drilling waste accumulation, and finally filling the entire drilling needle 2. What's worse, when the drilling needle 2 is put into drilling, the hole cannot be effectively formed, and the drilling needle 2 needs to be replaced, and the drilling waste needs to be manually removed before the needle is put back in. On the one hand, it affects the drilling efficiency. On the other hand, after multiple cleaning processes, it is inevitable that the structure of the drilling needle 2 itself will be affected, reducing the service life of the drilling needle 2.

[0038] The utility model inserts the ejecting needle 3 inside the drilling needle 2, and enables the end of the ejecting needle 3 to be retracted inward and outward relative to the drilling needle 2. This can eject the waste material remaining in the drilling needle 2 after the hole is drilled, so that the drilling waste material is completely separated from the drilling needle 2 and the hole-forming part of the pipe, avoiding the risk of the above-mentioned waste material adhering again, ensuring the hole-forming quality, improving the drilling efficiency, and extending the service life of the drilling needle 2.

[0039] In one specific embodiment, the drilling needle 2 specifically includes a hollow drilling needle 2 , which can be inserted into the drilling needle 2 by the ejecting needle 3 , and can also enable the ejecting needle 3 to eject the drilling waste from the drilling needle 2 opening of the drilling needle 2 .

[0040] Furthermore, the ejector needle 3 includes an ejector rod of a solid structure, which can ensure the thrust force applied to the waste material during the extension process and reduce the secondary retention of the waste material in the ejector needle 3.

[0041] Preferably, based on the pushing action of the ejector needle 3 on the waste material in the drilling needle 2, in order to ensure that the drilled waste material is reliably pushed out of the drilling needle 2, the applied pushing force should act on the axial direction of the drilling needle 2 to prevent deviation during the pushing process.

[0042] Based on this, the drilling needle 2 and the ejecting needle 3 are coaxially arranged, so that the ejecting needle 3 can be telescopically moved along the axial direction of the drilling needle 2, thereby ensuring that the drilled waste is pushed outward in the axial direction of the drilling needle 2.

[0043] By axially pushing the waste material in the drilling needle 2 with the ejecting needle 3, the drilling waste material can be completely separated from the drilling needle 2, thereby ensuring the drilling quality. The drilling ejecting tool in the utility model is particularly suitable for drilling holes in thin-walled, thick and thick pipes. It is preferably suitable for the drilling needle 2 to push and discharge the drilling waste material from the drilling needle 2 after passing through the pipe radially and drilling paired holes on the pipe, and then separate the drilling needle 2 from the pipe for subsequent drilling operations.

[0044] In order to enable the ejector needle 3 in the form of a push rod to axially expand and contract in the drilling needle 2, the ejector needle 3 and the drilling needle 2 are in a clearance fit relationship. At the same time, in order to increase the contact area between the end face of the ejector needle 3 and the drilling waste, the end face of the ejector needle 3 is a pushing plane, and the outer diameter of the ejector needle 3 is not less than 80% of the inner diameter of the drilling needle 2. Under the premise of taking into account the axial expansion and contraction of the ejector needle 3, its effective contact area with the waste can be guaranteed, thereby enhancing the reliability of the pushing operation.

[0045] The hollow drilling needle 2 comprises a drilling needle cavity 21 of a straight-through structure, and the ejecting needle 3 integrally passes through the drilling needle cavity 21 of the hollow drilling needle 2 .

[0046] The drilling needle cavity 21 of the hollow drilling straight-through structure can, on the one hand, facilitate the drilling process and provide a retention space for drilling waste, and on the other hand, allow the ejecting needle 3 to move axially in the drilling needle cavity 21, while facilitating the inward and outward extension and retraction of the ejecting needle 3 relative to the drilling needle hole.

[0047] In order to ensure reliable ejection, the ejection needle 3 integrally penetrates the drilling needle cavity 21 of the hollow drilling needle 2, so that the ejection needle 3 can eject the material when extended relative to the drilling needle hole, and can be accommodated in the drilling needle cavity 21 when retracted.

[0048] In the utility model, the drilling needle 2 is driven to rotate by the drilling motor 1 and is clamped and fixed by a clamp. Specifically, from the connection and installation angle of the drilling needle 2, the output end of the drilling motor 1 is connected to the drilling needle clamp 11, and the drilling needle 2 is vertically installed and clamped and fixed on the drilling needle clamp 11.

[0049] Through this setting method, the drilling needle 2 can be clamped and fixed on the drilling needle clamp 11. Combined with the drilling needle clamp 11 connected to the output end of the drilling motor 1, the drilling motor 1 can drive the drilling needle clamp 11 and the drilling needle 2 clamped and fixed on the drilling needle clamp 11 to rotate synchronously.

[0050] Compared with the horizontal arrangement of the pipe, the drilling needle 2 is installed vertically, which is conducive to the drilling needle 2 drilling holes in the side wall of the pipe during the rotation process.

[0051] During the specific operation process, the drilling and blasting tooling is installed as a whole on the punching machine, and the punching machine controls the overall lifting of the drilling and blasting tooling, so that the drilling motor 1 can operate independently during the lifting process, and drilling is performed along with the overall downward movement of the drilling and blasting tooling. The overall lifting of the drilling and blasting tooling is not the main body in this application and is explained here.

[0052] The ejection needle 3 in the present application is used to eject the drilling needle 2 from top to bottom. In order to enable the ejection needle 3 to extend into the drilling needle cavity 21 of the straight-through structure of the drilling needle 2 without being blocked by the drilling motor 1 in the middle, the drilling motor 1 in the present application is a hollow shaft stepper motor. The hollow shaft stepper motor includes a hollow rotating shaft (not shown in the figure) that penetrates the axial thickness of the motor and extends downward. The hollow rotating shaft serves as an output end, and can be connected to the drilling needle clamp 11 thereon. Specifically, the drilling needle clamp 11 is sleeved on the protruding part of the hollow rotating shaft and can rotate synchronously with the hollow rotating shaft.

[0053] The drilling needle clamp 11 includes a connecting seat 11a and a clamping cone 11b. The connecting seat 11a is mainly used for connecting to the clamp on the hollow rotating shaft, and the clamping cone 11b is mainly used for clamping and fixing the drilling needle 2. In order to reduce the interference between the top end of the drilling needle 2, that is, the clamping end of the drilling needle 2 and the hollow rotating shaft, the clamping end of the drilling needle 2 does not exceed the connection between the connecting seat 11a and the clamping cone 11b, that is, the clamping end of the drilling needle 2 is set within the clamping range of the clamping cone 11b, ensuring that the connection and installation of the drilling needle 2 are effective and reliable.

[0054] From the installation angle of the ejector needle 3, the ejector needle 3 is clamped and fixed on the ejector needle fixture 4, and the ejector needle fixture 4 is arranged above the drilling motor 1. The ejector needle 3 penetrates the ejector needle fixture 4, the drilling motor 1 and the drilling needle fixture 11 from top to bottom and is inserted into the hollow drilling needle 2.

[0055] Specifically, the clamping cone of the ejector needle fixture 4 is oriented opposite to the clamping cone 11b of the drilling needle 2. According to the figure, the clamping cone 11b of the drilling needle 2 is set downward, and the clamping cone of the ejector needle fixture 4 is set upward, which can ensure that the ejector needle 3 and the drilling needle 2 do not affect each other.

[0056] From the angle that the ejection needle 3 can be axially extended and retracted relative to the drilling needle 2, a lifting mechanism is installed on the upper part of the drilling motor 1. In the present application, the lifting mechanism is specifically a cylinder 5 installed on the drilling motor 1, and the cylinder 5 includes a telescopic rod 51 that can move in the vertical direction. The ejection needle clamp 4 is connected to the telescopic rod 51. The cylinder 5 and the telescopic rod 51 can drive the ejection needle clamp 4 and the ejection needle 3 to move up and down, thereby enabling the ejection action of the waste material in the drilling needle 2 to occur.

[0057] Preferably, the telescopic rod 51 in this embodiment is also in the form of a hollow rod, which can facilitate the passage of the ejection needle 3 without affecting its axial movement.

[0058] The cylinder 5 is connected to a driving air inlet pipe 52 and a driving air outlet pipe 53. Since the ejector needle fixture 4 is arranged at the top, the movement of the ejector needle 3 can be controlled by air intake and exhaust.

[0059] During specific operation, the cylinder 5 drives the air intake pipe 52 to continuously intake air, so that the ejector needle fixture 4 moves up and always remains in the upper starting position. The starting position corresponds to the state where the ejector needle 3 is lifted and does not fall to eject the material.

[0060] After the drilling needle 2 completes the drilling, the drilling waste will remain in the drilling needle 2. The cylinder 5 is exhausted by driving the air outlet pipe 53 to move the ejector needle fixture 4 downward. Combined with the clamping state of the ejector needle fixture 4 on the ejector needle 3, the ejector needle 3 moves down to eject the drilling waste in the drilling needle 2. Then the cylinder 5 continues to intake air to eject the ejector needle 3 back to its initial position. Through this setting, the ejector needle 3 can be extended and retracted multiple times after drilling once to ensure the complete discharge of the waste in the drilling needle 2.

[0061] In addition to using the cylinder 5, the lifting mechanism can also be in the form of an electric push rod or a screw shaft screw, which can also achieve the technical purpose of controlling the lifting and lowering of the ejector needle clamp 4, and will not be repeated here.

[0062] The utility model also provides a drilling device, including a drilling table and the above-mentioned drilling and ejecting tooling. The pipe is on the drilling table, and the punching machine drives the drilling and ejecting tooling to move downward as a whole. The pipe is drilled along with the downward movement of the drilling motor. After the drilling is completed, the waste material after drilling is ejected from the drilling needle through the ejecting needle of the drilling and ejecting tooling.

[0063] By means of the drilling and ejecting tooling and the drilling device of the utility model, the hole forming quality of the pipe is effectively improved and the service life of the drilling needle is prolonged.

[0064] It should be noted that, in the absence of conflict, the features in the embodiments of this application may be combined with each other.

[0065] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
