Description

Technical Field

[0001] This utility model relates to the field of drilling machine manufacturing technology, specifically a drilling machine for processing cabinets with a correction structure. Background Technology

[0002] Currently, when machining such workpieces, most vertical drilling machines use manual marking and positioning, followed by fixing with common fixtures such as clamping plates and vises. First, manual positioning and clamping rely entirely on the operator's experience, resulting in poor repeatability and easy deviations in drilling position due to human factors. In other words, the ability to correct deviations is weak, which affects the assembly quality of the cabinet. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a drilling machine for cabinet processing with a correction structure, which solves the problem of drilling position deviation.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a drilling machine for cabinet processing with a correction structure, comprising a vertical drilling machine and a worktable assembly. The outer wall of the vertical drilling machine is fixedly connected to the inner wall of the worktable assembly. The worktable assembly includes a worktable, an adjusting frame is slidably connected to the outer wall above the worktable, a centering clamping plate is slidably connected to the inner wall of the adjusting frame, a bushing frame is fixedly connected to the outer wall of the centering clamping plate, a shaft frame is fixedly connected to the outer wall of the adjusting frame, and a bidirectional threaded rod is threadedly connected to the inner wall of the bushing frame. Rotating the bidirectional threaded rod can drive the centering clamping plate to move horizontally left and right to achieve centered clamping of the workpiece. Through a bidirectional threaded transmission mechanism integrated on the worktable, the single rotational motion is efficiently converted into synchronous symmetrical linear motion of the two clamping plates, which can automatically and quickly position and clamp the regularly shaped workpiece at the center of the worktable, fundamentally eliminating the error caused by repeated manual adjustment of positioning, ensuring the uniformity of the drilling processing benchmark, and improving processing efficiency. This built-in correction structure is more compact and easier to operate compared to traditional external clamps.

[0005] Preferably, the inner wall of the shaft bracket away from the adjusting frame is rotatably connected to the outer wall of the bidirectional threaded rod. A guide plate is fixedly connected to the outer wall above the shaft bracket. The outer wall above the bushing bracket fits against the outer wall below the guide plate. To prevent the bushing bracket from flipping, two central clamping plates are provided. Although the added guide structure is simple, it improves the structural rigidity and motion stability of the entire clamping mechanism and prevents adverse phenomena such as lifting or deflection that may occur during the movement and clamping of the clamping plates. This not only makes the clamping action smooth and reliable and extends the service life of the mechanism, but also ensures that the workpiece is evenly stressed and positioned when clamped, further consolidating and improving the overall reliability of the correction.

[0006] Preferably, a threaded sleeve is fixedly connected to the middle of the outer wall below the adjustment frame, and an adjusting threaded rod is threadedly connected to the inner wall of the threaded sleeve. A central hole is opened in the middle of the inner wall of the worktable. After clamping the workpiece once, the operator can adjust the processing position of the workpiece in the front-back direction by simple turning operation, so as to realize continuous processing of multiple holes and multiple stations, avoid repeated positioning and clamping, avoid the cumulative error caused by multiple clamping, and ensure the relative position between multiple holes.

[0007] Preferably, the outer wall of the adjusting threaded rod near the central hole is rotatably connected to the inner wall of the worktable, and the rotating adjusting threaded rod can drive the adjusting frame to move horizontally back and forth.

[0008] This utility model provides a drilling machine for processing cabinets with a correction structure. It has the following advantages: (I) This type of drilling machine for cabinet processing with a correction structure, through the threaded transmission cooperation between the bidirectional threaded rod and the bushing frame, drives two sets of centering clamping plates to move closer synchronously and symmetrically, which can automatically center and clamp the workpiece, eliminating the reference deviation caused by manual positioning from the root, and realizing centering correction. With the guide plate above the bushing frame for limiting guidance, it can prevent the bushing frame from reversing, lifting or deflecting, improve the structural rigidity and motion stability of the clamping mechanism, ensure that the workpiece is subjected to uniform force and firmly positioned, provide reliable reference guarantee for drilling processing, and improve the effect of hole processing.

[0009] (II) This drilling machine for cabinet processing with a correction structure can move the adjustment frame and the workpiece horizontally back and forth along the worktable by simply rotating the adjusting threaded rod after the workpiece is centered and clamped. This can quickly realize the adjustment of the processing position of multiple stations, avoid the cumulative error caused by multiple clamping, ensure the relative position between multiple holes, and the built-in correction structure is more compact than the traditional external fixture. The operation process is simplified, the clamping and station adjustment time is shortened, and the efficiency of continuous processing of multiple holes in cabinet processing is improved.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Please see Figure 1-4 This utility model provides a drilling machine solution for cabinet processing with a correction structure: it includes a vertical drilling machine 1, and a worktable assembly 3. The outer wall of the vertical drilling machine 1 is fixedly connected to the inner wall of the worktable assembly 3. The worktable assembly 3 includes a worktable 31. An adjustment frame 33 is slidably connected to the outer wall above the worktable 31. A centering clamping plate 36 is slidably connected to the inner wall of the adjustment frame 33. A bushing frame 35 is fixedly connected to the outer wall of the centering clamping plate 36. A shaft frame 38 is fixedly connected to the outer wall of the adjustment frame 33. A two-way threaded rod 32 is threadedly connected to the inner wall of the bushing frame 35. Rotating the two-way threaded rod 32 can drive the centering clamping plate 36 to move horizontally left and right to achieve the purpose of centering and clamping the workpiece.

[0014] The inner wall of the shaft bracket 38 away from the adjusting frame 33 is rotatably connected to the outer wall of the bidirectional threaded rod 32. A guide plate is fixedly connected to the outer wall above the shaft bracket 38. The outer wall above the shaft sleeve bracket 35 is in contact with the outer wall below the guide plate. To prevent the shaft sleeve bracket 35 from flipping, two central clamping plates 36 are provided.

[0015] A threaded sleeve is fixedly connected to the middle of the outer wall below the adjusting frame 33. An adjusting threaded rod 34 is threadedly connected to the inner wall of the threaded sleeve. A central hole 37 is opened in the middle of the inner wall of the worktable 31. The outer wall of the adjusting threaded rod 34 near the central hole 37 is rotatably connected to the inner wall of the worktable 31. Rotating the adjusting threaded rod 34 can drive the adjusting frame 33 to move horizontally back and forth.

[0016] In use, the workpiece to be processed in the cabinet is first placed in the adjustment frame 33 of the worktable 31. By rotating the bidirectional threaded rod 32, the rotational motion is converted into linear motion through the threaded transmission between it and the bushing frame 35. Due to the thread of the bidirectional threaded rod 32, the bushing frames 35 on both sides move synchronously in opposite directions, thereby driving the two sets of centering clamping plates 36 to move symmetrically closer, automatically clamping and positioning the workpiece in the center position of the worktable 31, eliminating the reference deviation caused by manual positioning from the root, and realizing the centering correction function. At the same time, the guide plate above the bushing frame 38 is in contact with the upper surface of the bushing frame 35 to form a limiting guide structure, preventing the bushing frame 35 from reversing, lifting or deflecting during the movement, improving the structural rigidity and movement stability of the clamping mechanism, ensuring that the workpiece is evenly stressed and firmly positioned when clamped, further consolidating the correction effect, providing a stable clamping foundation for drilling, and aligning the rotating head of the vertical drilling machine 1 with the center hole 37.

[0017] The multi-station adjustment principle allows for continuous multi-hole or multi-station machining without repeated workpiece clamping after the workpiece is centered and clamped. Simply rotate the adjusting threaded rod 34, which engages with the threaded sleeve below the adjusting frame 33 to move the entire adjusting frame 33 and the clamped workpiece horizontally back and forth along the worktable 31. This adjusts the workpiece's machining position in the front-back direction without disassembling the workpiece, avoiding cumulative errors caused by multiple clamping operations and ensuring the relative positional accuracy between multiple holes, thus meeting the requirements for continuous multi-hole machining in cabinet processing.

[0018] Based on the principle of overall machining coordination, the vertical drilling machine 1 is fixedly connected to the worktable assembly 3. After the workpiece has completed centering correction, stable clamping, and position adjustment, the vertical drilling machine 1 carries out drilling operations based on the established unified machining benchmark. Compared with traditional external fixtures, the built-in bidirectional threaded drive correction structure is more compact and easier to operate. Through the coordinated operation of automatic centering correction, stable clamping, and position adjustment, the uniformity of the machining benchmark is ensured, and the machining efficiency and hole machining accuracy are improved.
