Description

Technical Field

[0001] This utility model relates to the field of through-hole technology, specifically to a deburring milling cutter for through-holes of workpieces used in a pin-blocking detection sensor. Background Technology

[0002] Currently, for the workpiece of the needle blockage detection sensor made of polymer materials, its structure is a stepped cuboid. In the production process of the workpiece, a small through hole needs to be machined through the top of the workpiece. The most common problem in this process is that too many burrs are generated in the through hole and are difficult to clean. The time spent cleaning the burrs is included in the working hours, resulting in low production efficiency and high processing costs.

[0003] After the through holes of the existing polymer material-processed plugging needle detection sensor workpiece are opened, there are too many burrs on the inner wall of the through hole, which are difficult to clean. This causes the time spent on subsequent burr cleaning to be included in the working hours, resulting in low production efficiency and high processing costs. Therefore, a deburring milling cutter for the through holes of plugging needle detection sensor workpieces is proposed. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a deburring milling cutter for through holes in a plugged needle detection sensor workpiece. This provides a set of milling cutter components that integrate hole opening and deburring for through hole machining operations on plugged needle detection sensor workpieces. After the through hole of the plugged needle detection sensor workpiece is opened, the inner wall of the through hole can be deburred based on the side cutter during the retraction process, thereby improving the quality of the through hole used in the plugged needle detection sensor workpiece.

[0005] The technical solution adopted by this utility model to solve its technical problem is a deburring milling cutter for a through hole of a workpiece for a blocked needle detection sensor, including a cutter body and a cutter body, wherein the cutter body is inserted into the bottom of the cutter body.

[0006] The cutter body includes a milling cutter head, a hexagonal inner rod, and side cutters. The hexagonal inner rod is fixedly connected to the top center of the milling cutter head. A narrow rod is connected to the top of the hexagonal inner rod, and a rod head is provided on the top of the narrow rod. Two sets of side cutters are provided and are located on both sides of the rod head. The blade of the side cutter is bent, and the top of the handle of the side cutter is rotatably connected to the rod head through a pivot.

[0007] By adopting the above technical solution, a milling cutter assembly consisting of a cutter body and a cutter blade is provided for the through-hole machining of the workpiece of the plugged needle detection sensor. After the through-hole of the workpiece of the plugged needle detection sensor is opened, the inner wall of the through-hole can be deburred based on the side cutter during the retraction process, thereby improving the quality of the through-hole of the workpiece of the plugged needle detection sensor.

[0008] Specifically, the blade includes a sleeve and a spring. The bottom of the sleeve has an internal hexagonal socket corresponding to the hexagonal inner rod, and the hexagonal inner rod is inserted into the internal hexagonal socket.

[0009] By adopting the above technical solution, the hexagonal inner rod and the internal hexagonal socket can provide a certain guiding function during the extension and retraction of the hexagonal inner rod within the internal hexagonal socket, ensuring the integrity of the blade body and the blade tip during rotation.

[0010] Specifically, the sleeves extending through the internal hexagonal sockets have side openings corresponding to the side blades.

[0011] By adopting the above technical solution, and through the setting of the side opening, after the pressure is lost at the bottom of the hexagonal inner rod, the blade of the side cutter can extend through the side opening to grind and deburr the hole wall.

[0012] Specifically, the spring is located at the top of the internal hexagon socket, the spring is set at the top of the rod head, the bottom of the spring is connected to the rod head, and the top of the spring is connected to the top of the internal hexagon socket.

[0013] By adopting the above technical solution, the spring is released after the milling cutter head loses pressure, pushing the rod head downwards, and the cutter bodies of the side cutters on both sides of the rod head lose their limit, allowing the cutter heads of the side cutters to extend out of the side opening.

[0014] The beneficial effects of this utility model are as follows: The assembly, consisting of a cutter body and a cutter blade, provides a set of milling cutter components that integrate hole opening and deburring for through-hole machining of plugged needle detector workpieces. After opening the through-hole of the plugged needle detector workpiece, deburring can be performed on the inner wall of the through-hole during the retraction process, thereby improving the quality of the through-hole in the plugged needle detector workpiece. This achieves hole opening upon entry and deburring upon retraction, completing the hole opening and deburring work in one step, greatly increasing processing efficiency and effectively reducing deburring costs. It solves the problem that after opening the through-hole of plugged needle detector workpieces made of polymer materials, excessive and difficult-to-clean burrs remain on the inner wall of the through-hole, resulting in low production efficiency and high processing costs due to the time spent on subsequent burr cleaning being included in the machining time.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1-4 As shown, the present invention provides a deburring milling cutter for a through hole of a workpiece for a plugging needle detection sensor, comprising a cutter body and a cutter blade, wherein the cutter body is inserted into the bottom of the cutter blade.

[0023] The cutter body includes a milling cutter head 11, a hexagonal inner rod 12, and side cutters 15. The hexagonal inner rod 12 is fixedly connected to the top center of the milling cutter head 11. A narrow rod 13 is connected to the top of the hexagonal inner rod 12. A rod head 14 is provided on the top of the narrow rod 13. Two sets of side cutters 15 are provided and are located on both sides of the rod head 14. The blade of the side cutter 15 is bent, and the top of the handle of the side cutter 15 is rotatably connected to the rod head 14 through a pivot.

[0024] The present invention also includes a sleeve 21 and a spring 24 in the blade part. The bottom of the sleeve 21 is provided with an internal hexagonal insertion hole 22 corresponding to the hexagonal inner rod 12, and the hexagonal inner rod 12 is inserted into the internal hexagonal insertion hole 22.

[0025] In use, the hexagonal inner rod 12 and the internal hexagonal socket 22 provide a certain guiding function during the extension and retraction of the hexagonal inner rod 12 within the internal hexagonal socket 22, ensuring the integrity of the blade body and the blade tip during rotation.

[0026] This utility model also includes side openings 23 corresponding to the side blades 15, with sleeves 21 extending through both sides of the internal hexagonal socket 22.

[0027] When in use, based on the setting of the side opening 23, after the pressure is lost at the bottom of the hexagonal inner rod 12, the blade of the side cutter 15 can extend through the side opening 23 to grind and deburr the hole wall.

[0028] The present invention also includes that the spring 24 is located at the top of the internal hexagon socket 22, the spring 24 is disposed at the top of the rod head 14, the bottom of the spring 24 is connected to the rod head 14, and the top of the spring 24 is connected to the top of the internal hexagon socket 22.

[0029] When in use, the spring 24 is released after the milling cutter head 11 loses pressure, pushing the rod head 14 downward, and the cutter bodies of the side cutters 15 on both sides of the rod head 14 lose their limit, so that the cutter heads of the side cutters 15 extend out of the side opening 23.

[0030] In use, the top of the sleeve 21 of the cutter body is installed in the collet of the milling machine's tool holder. The milling machine, based on the milling cutter of this application, performs the drilling operation on the workpiece of the plugged needle detection sensor. During operation, the milling machine's tool holder rotates, driving the cutter body and the bottom cutter body to work. The rotating milling cutter head 11 gradually descends to perform the drilling operation on the top of the plugged needle detection sensor workpiece. After the milling cutter head 11 contacts the plugged needle detection sensor workpiece, the milling cutter head 11 will be subjected to a certain pushing force, causing the hexagonal inner rod 12 at the top of the milling cutter head 11 to fully enter the internal hexagonal socket 22, so that the side cutter 15 is subjected to this pushing force and is stored in the side opening 2. Within 3, after the hole is drilled in the workpiece of the plugging needle detection sensor, during the retraction process of the milling machine, the milling cutter head 11 loses pressure, the pressure of the spring 24 is released, pushing the rod head 14 downward, and the cutter bodies of the side cutters 15 on both sides of the rod head 14 lose their limit, causing the cutter heads of the side cutters 15 to extend out of the side opening 23. At the same time, the milling machine continues to drive the cutter body to rotate, so that the side cutters 15 perform grinding and deburring on the inner wall of the through hole drilled in the workpiece of the plugging needle detection sensor based on the rotational force. The drilling and deburring operations can be completed in one set of feed and retraction processes, which is flexible and convenient to use and greatly increases the efficiency of drilling in the workpiece of the plugging needle detection sensor.

[0031] The specific length of the blade section is set according to actual usage requirements.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
