Description

Technical Field

[0001] This utility model relates to the field of horseshoe cutter head technology, specifically a horseshoe cutter head that facilitates the disassembly of cutting tools. Background Technology

[0002] In the field of machining, especially in milling, trimming and forming of wood, plastics and composite materials, horseshoe cutter heads are widely used as a high-efficiency cutting tool.

[0003] Traditional horseshoe cutter heads often employ an integral structure or bolt-fixed design, requiring the disassembly of multiple fasteners for tool replacement or maintenance. This process is cumbersome, time-consuming, and severely impacts production efficiency. Furthermore, some detachable cutter heads are prone to decreased positioning accuracy and loose connections after repeated assembly and disassembly, leading to tool imbalance, affecting machining quality, and even causing equipment vibration or safety accidents. Additionally, existing structures lack rapid alignment and limiting mechanisms for the upper and lower components of the cutter head, often requiring repeated manual adjustments during installation, making positioning difficult. Moreover, insufficient overall rigidity makes them prone to deformation or displacement under high-speed cutting conditions, weakening the stability and lifespan of the cutter head. Therefore, we propose a horseshoe cutter head that facilitates tool disassembly. Utility Model Content

[0004] The purpose of this utility model is to provide a horseshoe-shaped cutter head that facilitates tool disassembly, thereby solving the problems mentioned in the background art. Traditional horseshoe-shaped cutter heads mostly adopt an integral structure or bolt-fixed design, which requires the disassembly of multiple fasteners when replacing or maintaining tools. This operation is cumbersome and time-consuming, seriously affecting production efficiency. In addition, some detachable cutter heads are prone to problems such as decreased positioning accuracy and loose connections after repeated assembly and disassembly, resulting in unbalanced tool operation, affecting machining quality, and even causing equipment vibration or safety accidents. At the same time, the existing structure lacks a rapid alignment and limiting mechanism for the upper and lower components of the cutter head, which often requires repeated manual adjustments during installation, making positioning difficult. Moreover, the overall rigidity is insufficient, and deformation or displacement is prone to occur under high-speed cutting conditions, weakening the stability and service life of the cutter head.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a horseshoe-shaped cutter head for easy disassembly of cutting tools, comprising: a central cutter head;

[0006] It also includes: a lowering mechanism, which is located on the lower side of the central cutter head and is used to limit the movement of the central cutter head;

[0007] The upper disassembly mechanism is located on the upper side of the middle cutter head and is used to limit the movement of the middle cutter head.

[0008] The reinforcement mechanism is installed within the lower and upper dismantling mechanisms. It is used to reinforce the position between the cutter head, the lower dismantling mechanism, and the upper dismantling mechanism.

[0009] The lowering mechanism includes a lower cutter head located below the middle cutter head. Multiple positioning pins are fixedly connected to the bottom of the lower cutter head, and multiple positioning ball rods are fixedly connected to the top of the lower cutter head.

[0010] The top of the lower cutter head is fixedly connected to multiple elliptical blocks.

[0011] The upper disassembly mechanism includes an upper cutter disc mounted on the middle cutter disc. Three positioning blocks are arranged between the upper cutter disc and the middle cutter disc. The upper cutter disc has positioning grooves that mate with the positioning blocks. The upper cutter disc and the positioning blocks are connected by two internal hex bolts.

[0012] The reinforcement mechanism includes a column set in the middle cutter head, the lower disassembly mechanism and the upper disassembly mechanism. The top of the column is fixedly connected to the column, and a threaded rod is fixedly connected to the top of the column. A threaded connecting disc is threadedly connected to the outside of the threaded rod.

[0013] The bottom of the column has an internal hexagonal groove.

[0014] The top of the upper cutter head has a slot for mating with an internal hex bolt.

[0015] This utility model has at least the following beneficial effects:

[0016] By incorporating a lower disassembly mechanism, an upper disassembly mechanism, and a reinforcement mechanism, along with multiple positioning elements such as positioning pins, positioning balls, elliptical blocks, and positioning blocks, the tool head assembly can be quickly aligned and assembled, significantly reducing tool change time. Furthermore, the multi-point positioning structure ensures concentricity and axial positional accuracy between the upper and middle tool heads, preventing vibration or uneven cutting caused by installation deviations, thus improving machining quality. The reinforcement mechanism, utilizing threaded rods and threaded connecting discs to apply uniform preload, compresses the three-layer structure into a single unit, significantly enhancing overall rigidity and torsional resistance, making it suitable for high-speed, heavy-duty cutting conditions. The coordination between these mechanisms ensures good fit accuracy after disassembly and assembly, thereby extending the tool head's service life. Attached Figure Description

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.

[0025] Example 1

[0026] Please see Figures 1 to 6 This utility model provides a technical solution: a horseshoe cutter head for easy disassembly of cutting tools, comprising: a central cutter head 1;

[0027] It also includes: a lowering mechanism 2, which is located on the lower side of the central cutter head 1 and is used to merge and limit the movement with the central cutter head 1;

[0028] The upper disassembly mechanism 3 is located on the upper side of the middle cutter head 1 and is used to merge and limit the movement with the middle cutter head 1.

[0029] The reinforcement mechanism 4 is installed inside the lower dismantling mechanism 2 and the upper dismantling mechanism 3. The reinforcement mechanism 4 is used to reinforce the position between the cutter head 1, the lower dismantling mechanism 2 and the upper dismantling mechanism 3.

[0030] The above-mentioned design, through the setting of a lower disassembly mechanism 2, an upper disassembly mechanism 3, and a reinforcing mechanism 4, along with multiple positioning elements such as positioning pin 22, positioning ball rod 23, elliptical block 24, and positioning block 32, enables rapid centering and assembly of the cutter head assembly, significantly shortening tool change time. Furthermore, the multi-point positioning structure ensures the concentricity and axial positional accuracy between the upper cutter head 31 and the middle cutter head 1, preventing vibration or uneven cutting caused by installation deviations, thereby improving machining quality. The reinforcing mechanism 4, using threaded rod 42 and threaded connecting disc 43 to apply uniform preload, compresses the three-layer structure into a single unit, significantly enhancing overall rigidity and torsional resistance, making it suitable for high-speed, heavy-duty cutting conditions. Moreover, the cooperation between these mechanisms ensures good fit accuracy after disassembly and assembly, thus extending the cutter head's service life.

[0031] The lowering mechanism 2 includes a lower cutter head 21 located below the middle cutter head 1. Multiple positioning posts 22 are fixedly connected to the bottom of the lower cutter head 21, and multiple positioning ball rods 23 are fixedly connected to the top of the lower cutter head 21.

[0032] In use, multiple positioning pins 22 and multiple positioning ball rods 23 on the lower cutter head 21 can be matched with the slots in the middle cutter head 1, thereby completing the splicing of the middle cutter head 1 and the lower cutter head 21.

[0033] The upper disassembly mechanism 3 includes an upper cutter disc 31 set on the middle cutter disc 1. Three positioning blocks 32 are set between the upper cutter disc 31 and the middle cutter disc 1. The upper cutter disc 31 has a positioning groove 34 that mates with the positioning blocks 32. The upper cutter disc 31 and the positioning blocks 32 are connected by two internal hexagon bolts 33 through internal threads.

[0034] In use, the positioning block 32 is inserted into the positioning groove 34 in the upper cutter head 31, and then the positioning block 32 is connected to the upper cutter head 31 using the internal hex bolt 33, so that it can be docked and assembled with the middle cutter head 1.

[0035] Example 2

[0036] like Figures 1 to 5 In this second embodiment, the other structures remain unchanged, but the difference from the first embodiment is:

[0037] The reinforcement mechanism 4 includes a column 41 disposed in the middle cutter head 1, the lower disassembly mechanism 2 and the upper disassembly mechanism 3. The top of the column 41 is fixedly connected to the column 41, and the top of the column 41 is fixedly connected to the threaded rod 42. The threaded rod 42 is threadedly connected to the outside of the threaded connecting plate 43. The bottom of the column 41 is provided with an internal hexagonal groove 44.

[0038] In use, the threaded rod 42 can be inserted into the lower cutter head 21, the upper cutter head 31 and the middle cutter head 1. Then, the threaded connecting plate 43 is placed into the upper cutter head 31. The cylinder 41 can be rotated by the internal hexagonal slot 44 so that the threaded rod 42 at the top of the cylinder 41 is connected to the threaded connecting plate 43, thereby completing the assembly of the middle cutter head 1, the lower cutter head 21 and the upper cutter head 31.

[0039] The top of the upper cutter head 31 has a slot for mating with the internal hex bolt 33;

[0040] In use, it is easy to connect and install the positioning block 32 and the upper cutter head 31 using the internal hex bolts 33.
