Description

Technical Field

[0001] This utility model relates to the field of horizontal milling machine head technology, and in particular to a structure for fine-tuning the angle of a horizontal milling machine head. Background Technology

[0002] The milling head of a horizontal milling machine is the core functional component of the machine. It refers to the power unit mounted on the machine tool column or ram and arranged horizontally along the spindle. It is used to drive the milling cutter to rotate and complete the cutting process. Its core feature is that the spindle axis is parallel to the worktable. By adjusting the angle and moving the position of the milling head, it can achieve multi-face machining of complex parts.

[0003] The existing angle adjustment mechanism of the milling head of the horizontal milling machine has problems such as low adjustment accuracy and cumbersome operation. When fine-tuning, the bolts need to be tightened and loosened repeatedly. Uneven tightening force can easily cause the milling head to deviate slightly. In addition, during heavy cutting, insufficient clearance and rigidity of the mechanical transmission chain can cause the milling head to vibrate or drift, which directly affects the accuracy of the machined surface.

[0004] Therefore, in view of the problems of insufficient adjustment accuracy and complicated operation of the existing horizontal milling machine head angle adjustment mechanism, specifically the problem that the bolts need to be tightened repeatedly during fine adjustment, resulting in uneven tightening and displacement, which seriously affects the machining accuracy, there is an urgent need to design a new type of horizontal milling machine head angle fine adjustment structure. Utility Model Content

[0005] In order to overcome the problems of insufficient adjustment accuracy and complicated operation of the existing horizontal milling machine head angle adjustment mechanism, specifically the problem that the bolts need to be tightened repeatedly during fine adjustment, resulting in uneven tightening and displacement, which seriously affects the machining accuracy.

[0006] The technical solution of this utility model is as follows: a milling head angle fine-tuning structure for a horizontal milling machine, including a fixed plate; and an adjustment component. The adjustment component is provided at the bottom of the fixed plate. The adjustment component includes a connecting plate, scales, sliding grooves, sliders, bolts, triangular blocks, positioning rods, connecting blocks, magnetic blocks, limiting posts, threaded grooves, and threaded rings. The lower end of the fixed plate is connected to the connecting plate. The top of the connecting plate has multiple scales at equal intervals. The inside of the connecting plate has a sliding groove, which is annular. A slider is slidably connected inside the sliding groove. A bolt is threadedly connected inside the slider. A triangular block is connected to the top of the slider. A positioning rod is connected to the bottom of the slider. A connecting block is cylindrical, and a magnetic block is connected to the bottom of the connecting rod. The lower end of the connecting plate is connected to the milling head body. A limiting post is connected to the front top of the milling head body. A threaded groove is provided at the outer end of the limiting post, and a threaded ring is threadedly connected to the outer end of the threaded groove.

[0007] Preferably, by setting an adjustment component, when it is necessary to fine-tune the milling head angle, the slider is rotated and slides in the sliding groove. After the triangular block points to the required scale, the bolt is rotated and squeezes the sliding groove, thereby limiting the slider. Then, the milling head body is rotated and rotates on the connecting plate. After being magnetically connected to the limiting post by the magnetic block on the connecting block, the threaded ring is rotated and rises to cooperate with the connecting block, which plays a limiting role and prevents the milling head body from shaking and deviating.

[0008] Preferably, the front end of the milling head body is connected to a mounting ring, and the top of the fixed plate is rotatably connected to an assembly ring.

[0009] Preferably, a cone is connected to the top of the assembly ring, and a retaining post is connected to the top of the cone.

[0010] Preferably, the front end of the mounting ring has multiple connecting holes at equal intervals, and the upper and lower sides of the front end of the mounting ring are connected with locking blocks.

[0011] Preferably, there are two card blocks, and the front end of each card block has the same connection hole.

[0012] Preferably, the outer side of the threaded ring is provided with multiple anti-slip grooves at equal intervals, and the threaded ring is movably connected to the limiting post.

[0013] Preferably, the magnetic block is magnetically connected to the limiting post, and the threaded ring is movably connected to the connecting block.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting an adjustment component, the slider in the sliding groove moves to align the triangular block with the target scale. After the rotating bolt locks the slider position, the milling head body can be freely rotated to the required angle. After adjustment, the magnetic block on the connecting block is attracted and positioned by the limiting post. Then, the rotating threaded ring and the connecting block form a double mechanical limit. This magnetic composite locking structure can not only ensure the angle adjustment accuracy, but also effectively prevent the milling head from deviating during the machining process, significantly improving machining stability. This solves the problems of insufficient adjustment accuracy and complicated operation of the existing horizontal milling machine milling head angle adjustment mechanism. Specifically, the need to repeatedly tighten the bolt during fine adjustment leads to uneven tightening and displacement, which seriously affects the machining accuracy. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4 This utility model provides an embodiment of a milling head angle fine-tuning structure for a horizontal milling machine, including a fixed plate 1 and an adjustment component. The adjustment component is located at the bottom of the fixed plate 1 and includes a connecting plate 21, scales 22, sliding grooves 23, sliders 24, bolts 25, triangular blocks 26, positioning rods 27, connecting blocks 28, magnetic blocks 29, limiting posts 210, threaded grooves 211, and threaded rings 212. The lower end of the fixed plate 1 is connected to the connecting plate 21. The top of the connecting plate 21 has multiple scales 22 at equal intervals. The interior of the connecting plate 21 has a sliding groove 23, which is annular. A slider 24 is slidably connected inside the sliding groove 23. Bolts 25 are threadedly connected inside the slider 24. A triangular block 26 is connected to the top of the slider 24. A positioning rod 27 is connected to the bottom of the slider 24. A connecting block 28 is connected to the bottom of the positioning rod 27. The connecting block 28 is circular. The milling head body 31 is connected to the bottom of the columnar connecting block 28 with a magnetic block 29. The lower end of the connecting plate 21 is connected to the milling head body 31. The top front side of the milling head body 31 is connected to a limiting post 210. The outer end of the limiting post 210 has a threaded groove 211. The outer end of the threaded groove 211 is threadedly connected to a threaded ring 212. By setting an adjustment component, when it is necessary to finely adjust the milling head angle, the slider 24 is rotated. The slider 24 slides in the sliding groove 23. After the triangular block 26 points to the required scale 22, the bolt 25 is rotated, so that the bolt 25 presses the sliding groove 23, thereby limiting the slider 24. Then the milling head body 31 is rotated. The milling head body 31 rotates on the connecting plate 21. After the magnetic block 29 on the connecting block 28 is magnetically connected to the limiting post 210, the threaded ring 212 is rotated. The threaded ring 212 rises and cooperates with the connecting block 28 to play a limiting role and prevent the milling head body 31 from shaking and deviating.

[0023] Please see Figures 1-4 In this embodiment, a mounting ring 32 is connected to the front end of the milling head body 31, and an assembly ring 33 is rotatably connected to the top of the fixed plate 1. The mounting ring 32 is used to install the tool. A cone 34 is connected to the top of the assembly ring 33, and a retaining post 35 is connected to the top of the cone 34. The cone 34 and the retaining post 35 facilitate the installation of the structure into the milling machine. Multiple connecting holes 36 are opened at equal intervals at the front end of the mounting ring 32. The upper and lower sides of the front end of the mounting ring 32 are connected to retaining blocks 37, which facilitate the restriction of the tool position for installation.

[0024] Please see Figures 2-4 In this embodiment, two locking blocks 37 are provided. The front end of the locking blocks 37 is provided with the same connecting hole 36, which is used to connect with an external tool. Multiple anti-slip grooves are provided on the outer side of the threaded ring 212 at equal intervals. The threaded ring 212 is movably connected to the limiting post 210. The anti-slip grooves facilitate the rotation of the threaded ring 212 for limiting. The magnetic block 29 is magnetically connected to the limiting post 210. The threaded ring 212 is movably connected to the connecting block 28. The threaded ring 212 fits onto the connecting block 28, thereby achieving the limiting effect.

[0025] During operation, the locking pin 35 and the cone 34 are connected and installed with the external milling machine. After installation, the tool is installed on the mounting ring 32 through the locking block 37 and the connecting hole 36, thus completing the installation. Then, the slider 24 is moved, and the slider 24 in the sliding groove 23 moves to align the triangular block 26 with the target scale 22. After the bolt 25 is turned to lock the position of the slider 24, the milling head body 31 can be freely rotated to the required angle. After adjustment, the magnetic block 29 on the connecting block 28 is attracted and positioned by the limiting pin 210. Then, the threaded ring 212 is rotated to form a double mechanical limit with the connecting block 28. This magnetic composite locking structure can not only ensure the angle adjustment accuracy, but also effectively prevent the milling head from deviating during the machining process.

[0026] Through the above steps, by setting the adjustment component, the slider 24 in the sliding groove 23 moves to drive the triangular block 26 to align with the target scale 22. After the rotating bolt 25 locks the position of the slider 24, the milling head body 31 can be freely rotated to the required angle. After the adjustment is completed, the magnetic block 29 on the connecting block 28 is attracted and positioned by the limiting post 210. Then, the threaded ring 212 is rotated to form a double mechanical limit with the connecting block 28. This magnetic composite locking structure can not only ensure the angle adjustment accuracy, but also effectively prevent the milling head from deviating during the processing, significantly improving the processing stability. This solves the problems of insufficient adjustment accuracy and complicated operation of the existing horizontal milling machine milling head angle adjustment mechanism. Specifically, the problem is that the bolt 25 needs to be tightened repeatedly during fine adjustment, which leads to uneven tightening and deviating, seriously affecting the processing accuracy.
