[0002] The milling cutter disc is a commonly used cutting tool in metal processing, mainly used for processing operations on milling machines. It consists of several key components, including blades, tool holders, tool holders and tool fixing bolts. The blade is the core part of the milling cutter disc, which undertakes the actual cutting task and is connected to the milling cutter disc through the tool holder. The tool holder is used to install and support the blade to ensure stability and accuracy during the cutting process. The function of the tool fixing bolt is to fix the tool to prevent it from loosening during the processing. Choosing a suitable milling cutter disc depends on the specific processing requirements. Different types of milling cutter discs are suitable for different processing materials and processing methods, and can meet the needs of various processing tasks.

[0003] Although there are many types of existing clamps, including milling cutter disc clamps, there are still some problems in actual use. First, the existing milling cutter disc clamps are mostly fixed and cannot be adjusted, and the structure is rigid and not flexible enough. Second, the existing milling cutter disc clamps are mostly one-time installation, and there are defects in installation, disassembly and replacement. Third, it is difficult to maintain the accuracy of the existing milling cutter disc clamps during assembly and disassembly, the center of the clamp is easy to deviate, and the clamping firmness has room for improvement. Therefore, an assembly quick-disassembly milling cutter disc clamp is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example

[0023] Depend on Figure 1-4 Provided is an assembly quick-detachable milling cutter head fixture, comprising a fixed base 1 and three limit blocks 2;

[0024] Three limit blocks 2 are assembled in a ring shape on the upper end surface of the fixed base 1;

[0025] A slideway 20 is formed between two adjacent limit blocks 2, a positioning shaft 31 is installed between two adjacent limit blocks 2, and clamping blocks 3 are installed outside the three positioning shafts 31, and the three clamping blocks 3 are respectively located in the three slideways 20;

[0026] The upper end surface of the fixed base 1 has a groove and a mounting seat 4 is installed in the groove. The mounting seat 4 is located between the three limiting blocks 2. The outer circumferential surface of the mounting seat 4 is provided with three engaging grooves. One end of the three clamping blocks 3 is respectively engaged in the three engaging grooves.

[0027] In the present embodiment, by the mutual cooperation among the fixed base 1, the limit block 2, the clamping block 3 and the mounting base 4, the mounting base 4 is driven to move downward by rotating the threaded screw 41. When the mounting base 4 moves, one end of the three clamping blocks 3 engaged on the outside of the mounting base 4 is pulled, so that the three alignments are tilted, and finally the milling cutter disc is accurately clamped and fixed. The adjustable design makes the device adaptable to milling cutter discs of different sizes. The milling cutter disc can be easily clamped by rotating the threaded screw 41. The operation is simple. At the same time, the fixed base 1 and the limit block 2 can be disassembled and separated by removing a number of positioning bolts 21, which is very convenient.

[0028] Specifically, refer to Figure 2-4 A threaded screw 41 is provided at the center point of the upper end surface of the mounting seat 4. One end of the threaded screw 41 passes through the bottom of the fixed base 1 and is meshed and connected with the mounting seat 4 and the fixed base 1 through a thread.

[0029] In this embodiment, when the threaded screw 41 is rotated clockwise, the threaded screw 41 is limited by the fixed base 1, so that the threaded screw 41 moves downward when rotating, and drives the limit plate 42 at the upper end. The limit plate 42 is abutted against the mounting seat 4, and when the limit plate 42 moves downward, it drives the mounting seat 4.

[0030] Specifically, refer to Figure 3 A compression spring 11 is assembled on the outside of the lower end of the mounting seat 4 , and the lower end of the compression spring 11 is hooked with the bottom of the groove of the fixed base 1 .

[0031] In this embodiment, the compression spring 11 is located in the groove at the upper end of the fixed base 1 and is assembled on the outside of the lower end of the mounting seat 4. The compression spring 11 can push the mounting seat 4 upward due to its own elastic force and external tension, so that the mounting seat 4 that moves downward can eventually return to its original state.

[0032] Specifically, refer to Figure 1-2 The three limit blocks 2 are assembled on the upper end of the fixed base 1 through a plurality of positioning bolts 21.

[0033] In this embodiment, three limit blocks 2 are assembled on the upper end of the fixed base 1 through a plurality of positioning bolts 21, and are connected through the positioning bolts 21, so that the device is more convenient to maintain.

[0034] Specifically, refer to Figure 1-3 The upper end of the threaded screw rod 41 is equipped with a limit plate 42 and the lower end of the limit plate 42 is against the upper end surface of the mounting seat 4. The lower end of the threaded screw rod 41 is equipped with a handle 43 and the connection with the handle 43 is detachable.

[0035] In this embodiment, the limit plate 42 is disposed to abut against the upper end surface of the mounting seat 4. When the threaded screw 41 drives the limit plate 42 at the top downward, the limit plate 42 moves downward and drives the mounting seat 4 abutting against it.

[0036] Specifically, refer to Figure 1-3 , one side of the three clamping blocks 3 is provided with anti-slip texture.

[0037] In this embodiment, by providing anti-slip grooves on one side of the clamping block 3, the friction force can be increased, so that the three clamping blocks 3 can clamp the outer side of the milling cutter disc more stably at one end, thereby improving the overall stability of the device.

[0038] The utility model is a quick-detachable milling cutter head fixture:

[0039] In actual use, the user first places the milling cutter disc between the three clamping blocks 3, and then rotates the handle 43 at the lower end of the threaded screw 41 clockwise. The threaded screw 41 is limited by the fixed base 1, so that the threaded screw 41 moves downward when rotating, and drives the upper limit plate 42, and the set limit plate 42 is against the mounting seat 4. When the limit plate 42 moves downward, it drives the mounting seat 4, so that the mounting seat 4 moves downward and squeezes the compression spring 11 at the lower end, so that the compression spring 11 is in a taut state. At the same time, when the mounting seat 4 moves downward, one end of the three clamping blocks 3 is engaged in the mounting seat 4 and Pulled by the mounting seat 4, the clamping block 3 is limited by the set slideway 20. When one end of the three clamping blocks 3 is pulled downward, the other ends of the three clamping blocks 3 are synchronously tilted inwardly by cooperating with the limiting of the positioning shaft 31, and the milling cutter disc located in the middle is clamped and fixed. When the clamping and fixing needs to be cancelled, the handle 43 is rotated counterclockwise to make the threaded screw 41 upward. At this time, the compression spring 11 in a taut state pushes the mounting seat 4 upward due to its own elastic force and external tension, so that the mounting seat 4 is upward, and drives the three clamping blocks 3, and finally cancels the clamping and fixing of the milling cutter disc.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
