[0001] The utility model relates to the technical field of milling cutter seats, in particular to a milling cutter seat which is convenient for replacing a milling cutter. Background Art

[0002] The milling cutter seat is a component on the machine tool used to install and fix the milling cutter. The milling cutter seat is a device installed on the machine tool to fix and support the milling cutter for cutting processing. Its main function is to ensure the stability and precision of the milling cutter during operation. It is an indispensable and important component in mechanical processing. The milling cutter seat is usually composed of a clamp, a seat body and a fastening device. These parts work together to fix and support the milling cutter. The design of the milling cutter seat usually has the characteristics of simple structure, easy installation, high precision and long service life.

[0003] At present, the existing method of installing the milling cutter on the milling cutter seat is rather complicated. It is usually done by using a barrel screw to tighten and fix the milling cutter and the milling cutter seat. Although this method can effectively fix, the screws may be affected by external factors for a long time and rust and cause thread stripping, making it difficult for personnel to replace the milling cutter in the subsequent process, resulting in a reduction in the practicality of the milling cutter seat. Therefore, we have proposed a milling cutter seat that is easy to replace the milling cutter to solve the above problems. Utility Model Content

[0025] Furthermore, the outside of the convex plate 3 is symmetrically fixedly connected with two protrusions, and the protrusions are arc-shaped, and the two protrusions are adapted to the adjacent grooves. Specifically, through the setting of the protrusions and the grooves, after the protrusions enter the grooves, when the convex plate 3 rotates, the protrusions can be against the limit ring 2, thereby preventing the convex plate 3 from being separated from the tool holder body 1.

[0026] Furthermore, springs 9 are sleeved on the outside of the two damping rods 8, and the two ends of the springs 9 are fixedly connected to the adjacent side walls of the two adjacent fixing plates 7. Specifically, through the setting of the springs 9, the personnel can align the two protrusions on the outside of the protruding plate 3 with the two grooves at the bottom of the limiting ring 2, and then push the protruding plate 3 into the knife seat body 1. At this time, the top of the protruding plate 3 squeezes the bottom of the mounting plate 6, and then the mounting plate 6 squeezes the damping rod 8 and the spring 9 and moves the mounting plate 6 upward to make the protruding plate 3 enter the inside of the knife seat body 1, and then the protruding plate 3 is rotated to make the block 4 at the bottom of the two protrusions align with the limiting ring 2. The card slots opened on the top of the positioning ring 2 are aligned and inserted to lock, thereby achieving the positioning of the convex plate 3. The personnel releases the force to push the convex plate 3, and then the spring 9 loses the extrusion force and elastically recovers to push the adjacent fixing plate 7 and push the mounting plate 6 back to its position, so that the mounting plate 6 squeezes and positions the top of the convex plate 3, thereby achieving effective and convenient positioning of the convex plate 3 and the bottom milling cutter body 5. When removing, the convex plate 3 is squeezed and rotated to release the positioning of the card block 4 and the card slot, and the convex plate 3 is aligned with the groove and slides out, so that there is no need to use bolts, screws, etc. for fixing, which reduces the operating burden of personnel and improves the practicality of the milling cutter seat.

[0027] Furthermore, the tops of the two fixing plates 7 are fixedly connected to the top of the tool holder body 1, and the bottoms of the other two fixing plates 7 are fixedly connected to the top of the mounting plate 6. Specifically, through the setting of the fixing plates 7, the fixing plates 7 can be installed between the tool holder body 1 and the mounting plate 6 through the damping rod 8.

[0028] Furthermore, two card slots are symmetrically provided on the top of the limiting ring 2, and the two card blocks 4 are adapted to the adjacent card slots. Specifically, through the arrangement of the card blocks 4 and the card slots, after the convex plate 3 enters the interior of the knife seat body 1, the two convex blocks drive the two card blocks 4 to rotate by rotating the convex plate 3, and then the card blocks 4 are engaged with the card slots, thereby limiting the convex plate 3 to prevent the convex plate 3 from rotating and deviating.

[0029] Furthermore, the outside of the limiting ring 2 is fixedly connected to the bottom of the tool holder body 1 and the inner wall at the opening. Specifically, through the setting of the limiting ring 2, the limiting ring 2 can limit the convex plate 3 to prevent the convex plate 3 from accidentally falling with the milling cutter body 5.

[0030] In summary:

[0031] When the tool holder 1 is in the working state, the two ends of the guide plate 3 are in the working state, and the guide plate 3 is in the working state, so that the tool holder 1 is in the working state, and the tool holder 1 is in the working state, and the tool holder 1 is in the working state, so that the tool holder 1 is in the working state, and the tool holder 1 is in the working state, and the tool holder 1 is in the working state, so that the tool holder 1 is in the working state, and the tool holder 1 is in the working state, so that the tool holder 1 is in the working state, and the tool holder 1 is in the working state, so that the tool holder 1 is in the working state, and the tool holder 1 is in the working state,
