Description

Technical Field

[0001] This utility model relates to the technical field of machining equipment, and in particular to a double-hole machining device. Background Technology

[0002] In the field of machining, traditional cam-type machining centers typically only perform single drilling or tapping operations on materials. When machining products with double-hole structures, two independent power sources are often required for each operation, which not only increases equipment costs and floor space but also leads to low processing efficiency. Especially in scenarios requiring simultaneous drilling at two different locations, traditional equipment cannot achieve synchronous processing and must complete the process step-by-step, which is not only time-consuming and labor-intensive but also makes it difficult to guarantee the relative positional accuracy of the two holes. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "front," "rear," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model; the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance; furthermore, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "joined" should be interpreted broadly, 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 a connection within two components. For those skilled in the art, the specific meaning of the terms in this utility model can be understood according to the specific circumstances.

[0022] See Figure 1-3 This embodiment discloses a dual-hole processing device, including a feeding assembly 10, a blocking assembly 20, and a drilling assembly 30. The feeding assembly 10 is used to input materials and has a chuck 13 for fixing the materials at the output end; the blocking assembly 20 is used to block the material protrusion end to limit the protrusion length, and it is provided with a first drilling cutter 23 that passively drills out a first hole structure when the material protrudes; the drilling assembly 30 is provided with a second drilling cutter 31 that actively drills out a second hole structure.

[0023] Before the material is conveyed to the chuck 13 by the feeding assembly 10, it rotates and moves forward. Its protruding end contacts the stop surface 211 of the stop assembly 20. At this time, the contact pressure generated by the axial movement of the material drives the first drilling cutter 23 to form a first hole structure on the side of the material. When the material protrusion length reaches the set value, the protruding end of the material is blocked by the stop assembly 20 and cannot move forward. The chuck 13 fixes the material, and the drilling assembly 30 drives the second drilling cutter 31 to feed radially, machining a second hole structure on the side of the material. The entire process completes the double hole machining in a single clamping. The stop assembly 20 simultaneously performs the dual functions of limiting and passive machining.

[0024] Through the above technical solution, this application effectively solves the problem of complex structure of dual-hole processing equipment, realizes synchronous processing of dual holes under single power source drive, and the structure of the processed product is as follows: Figure 4 As shown in the diagram. Specifically, the material stop assembly 20 completes the first hole machining while limiting the material's extension length, eliminating the need for a separate drilling unit; the active drilling assembly 30 and the passive drilling action are spatially separated, avoiding machining interference; the entire device achieves machining sequence coordination through mechanical linkage, significantly improving machining efficiency. For example, in continuous processing, material conveying, limiting, and dual-hole machining can be completed sequentially at the same station, reducing the equipment's footprint by approximately 40%.

[0025] In this embodiment, the material blocking assembly 20 includes a material blocking arm 21 and a material blocking rotation drive 22. The output end of the material blocking rotation drive 22 is connected to the material blocking arm 21. The material blocking rotation drive 22 is used to rotate the material blocking arm 21 to enter or leave the material blocking position. The material blocking surface 211 of the material blocking arm 21 is in contact with the protruding end of the material. The first drilling cutter 23 is connected to the material blocking arm 21 and extends out of the material blocking surface 211.

[0026] The material stop rotation drive component 22 refers to the mechanism that drives the material stop arm 21 to rotate. Specifically, it can be implemented using a servo motor or a rotary cylinder, controlling the forward and backward positions of the material stop arm 21 through rotational motion. (See also...) Figure 2-3 The stop arm 21 refers to a rigid component with a stop surface 211, which can be implemented using metal sheet or a robotic arm structure, and is used to limit the material extension length at the stop position. The stop surface 211 refers to a plane or curved surface that contacts the material extension end, and can be implemented using a contact surface covered with wear-resistant material, for precise material positioning. The first drilling cutter 23 refers to a cutting tool fixed on the stop arm 21, which can be implemented using a carbide drill bit or a replaceable insert structure. When the stop surface 211 contacts the material, it passively drills along with the material feed. The stop arm 21 is provided with a drill positioning hole 212. After the first drill is inserted into the stop arm 21, the drill is positioned by screwing fasteners into the drill positioning hole 212 to hold the drill.

[0027] In this embodiment, the cutting edges of the first drilling cutter 23 and the second drilling cutter 31 are in the same direction.

[0028] After the material is fixed by the chuck 13, the first drilling cutter 23 passively drills as the material feeds during contact with the stop arm 21, while the second drilling cutter 31 actively feeds under the control of the drive mechanism to complete the drilling. Since the cutting edges of the two cutters maintain the same direction, the material can be processed synchronously with the double-hole structure without needing to adjust its posture. For example, when processing cylindrical materials, the cutting directions of both cutters extend along the material's axis, ensuring consistent chip removal paths. This application achieves consistent control of the cutting direction of the cutters during double-hole processing, avoiding the accumulation of processing errors caused by differences in cutter directions. The cutting force direction experienced by the material remains constant during both drilling processes, effectively reducing the probability of hole position deviation. With the cutter directions unified, the equipment does not require an additional direction adjustment mechanism, simplifying the processing flow.

[0029] In this embodiment, the feeding assembly 10 further includes a feeding translation drive 11. The output end of the feeding translation drive 11 is connected to a feeding rotation drive 12. The feeding translation drive 11 is used to push the material into the chuck 13, and the feeding rotation drive 12 is used to drive the material to rotate for drilling. The feeding translation drive 11 is a power device capable of generating linear motion, specifically a linear motor or cylinder. Its function is to feed the material axially into the chuck 13 through linear thrust. When the material is pushed to the stop arm 21 by the feeding translation drive 11, the chuck 13 rotates, causing the material to rotate. At this time, the second drilling cutter 31 actively drills the material to form a second hole structure. The linear motion trajectory of the feeding translation drive 11 is consistent with the axial direction of the chuck 13, ensuring that the material is accurately pushed into the chuck 13 and fixed, avoiding drilling position deviation due to material offset.

[0030] In this embodiment, the drilling assembly 30 further includes a drilling translation drive 32, the output end of which is connected to the first drilling cutter 23. The drilling translation drive 32 is used to drive the first drilling cutter 23 closer to the material. The drilling assembly 30 also includes a tool holder 33, a tapping cutter 34, and a shifting rotation drive 35. The output end of the drilling translation drive 32 is connected to the shifting rotation drive 35, and the output end of the shifting rotation drive 35 is connected to the tool holder 33. The tapping cutter 34 and the second drilling cutter 31 are both connected to the tool holder 33.

[0031] The drilling translation drive 32 is a linear motion mechanism that drives the first drilling cutter 23 closer to the material. It can be implemented using a pneumatic or hydraulic cylinder, using linear motion to push the cutter into contact with the material for machining. The output end of the drilling translation drive 32 is fixedly connected to the shifting rotary drive 35. When it is necessary to switch machining tools, the shifting rotary drive 35 drives the tool holder 33 to rotate by a set angle, aligning the tapping cutter 34 or the second drilling cutter 31 with the material machining position. In the drilling process, the second drilling cutter 31 completes the active drilling action through the advancement of the translation drive; in the tapping process, the tapping cutter 34 completes thread machining under the advancement of the translation drive. The rotational positioning accuracy of the tool holder 33 is achieved through closed-loop control of a servo motor, ensuring that different tools accurately reach the machining position.

[0032] The drilling translation drive 32 pushes the shifting rotary drive 35 to move closer to the material. At this time, the shifting rotary drive 35 drives the tool holder 33 to rotate, so that the second drilling cutter 31 is aligned with the material for drilling. After drilling is completed, the shifting rotary drive 35 rotates the tool holder 33 again, so that the tapping cutter 34 is aligned with the drilled hole for tapping. The tool holder 33 switches tool positions by rotating, so that the drilling and tapping processes can be completed continuously under the same power source.

[0033] This application integrates drilling and tapping processes, avoiding the increased equipment size caused by the separation of power sources in traditional processes. The tool holder 33's rotational switching method allows both tools to share the same feed path, ensuring machining position accuracy and simplifying equipment maintenance procedures.

[0034] In this embodiment, the dual-hole processing device further includes a cutter assembly 40, which includes a cutter drive 41 and a cutting blade 42. The output end of the cutter drive is connected to the cutting blade 42, and the cutting blade 42 is used to cut off the protruding end of the material so that the material drilled out of the first hole structure and the second hole structure forms a dual-hole processed product.

[0035] After the material has completed the processing of the first and second hole structures, the cutter drive is activated, pushing the cutter 42 towards the material's protruding end. When the cutter 42 contacts the material, its cutting edge applies a shearing force perpendicular to the axial direction, cutting the material at the end of the double-hole structure. The cut material retains the double-hole structure and forms an independent product, while the unprocessed portion remains in the chuck 13 awaiting the next processing cycle.

[0036] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
