DETAILED DESCRIPTION

[0023] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. The preferred embodiments in the description are only used as examples. All other embodiments obtained by those skilled in the art without making any creative work are within the scope of protection of the present invention.

[0024] like Figures 1-4 As shown, this specific embodiment adopts the following technical solution: it comprises a mounting base 1 and a connecting tube 2, and the connecting tube 2 is fixedly provided on the mounting base 1;

[0025] It also contains:

[0026] The clamping cylinder 3 is movably inserted into the connecting cylinder 2. Several expansion joints 4 are provided on the circular side wall of the clamping cylinder 3 at equal rounded corners. The inner wall of the clamping cylinder 3 is provided with anti-slip grooves 13. The anti-slip grooves 13 can increase the friction generated between the inner wall of the clamping cylinder 3 and the milling cutter, thereby making the fixation of the milling cutter more stable. Several guide blocks 12 are distributed on the circular corners of the outer ring wall of the clamping cylinder 3. The guide blocks 12 are movably set in the guide grooves provided on the inner wall of the connecting cylinder 2. The guide blocks 12 can provide a mobile guide for the clamping cylinder 3 to prevent the clamping cylinder 3 from rotating in the connecting cylinder 2;

[0027] Spring 5, the spring 5 is fixedly arranged in the connecting tube 2, and one end of the spring 5 is connected to the clamping tube 3. An extrusion block 6 is fixedly arranged on the outer ring wall of the clamping tube 3 between adjacent expansion joints 4, and the extrusion block 6 is movably arranged in contact with the inclined opening 7 opened on the left side of the connecting tube 2. The clamping tube 3 is made of a tough material and has a certain elastic deformation performance;

[0028] The internal thread locking cover 8 is sleeved on the connecting tube 2 by threaded rotation. The inner wall of the internal thread locking cover 8 is movably in contact with the extrusion block 6. The left end of the clamping tube 3 is provided with a correction adjustment mechanism 9 after passing through the internal thread locking cover 8. The internal thread locking cover 8 is provided with a plurality of reinforcing ribs 14 distributed on the rounded corners. The reinforcing ribs 14 can not only improve the structural strength of the internal thread locking cover 8, but also increase the friction generated by the hand when the internal thread locking cover 8 is screwed, thereby avoiding the hand slipping phenomenon.

[0029] The deviation correction and adjustment mechanism 9 comprises:

[0030] Threaded rod 9-1, there are several threaded rods 9-1, with equal fillets and threaded through the side wall of the clamping cylinder 3, and a cross cap 9-2 is fixed on one end of the threaded rod 9-1;

[0031] Adjustment plates 9-3, there are several adjustment plates 9-3, which are rotatably arranged on the other ends of the several threaded rods 9-1 through bearings. The inner wall of the opening of the clamping cylinder 3 is provided with a resistance groove 10 between adjacent expansion joints 4, and the adjustment plates 9-3 are movably disposed in the resistance groove 10;

[0032] There are several guide rods 9-4, which are fixed in groups of two on the side walls of several adjustment plates 9-3 and located on both sides of the threaded rod 9-1. The guide rods 9-4 are movably inserted into the cylindrical groove 11 opened on the inner wall of the interference groove 10.

[0033] When using the present invention, the milling cutter is inserted into the clamping cylinder 3, and then the internal thread locking cover 8 is rotated to move the internal thread locking cover 8 to the right. The internal thread locking cover 8 squeezes the clamping cylinder 3 to the right through the extrusion block 6 and compresses the spring 5. The cooperation of the extrusion block 6 and the inclined mouth 7 can make the clamping cylinder 3 deform, and the expansion gap 4 is reduced. The inner wall of the clamping cylinder 3 can firmly contact the milling cutter, so that the clamping cylinder 3 can clamp and fix the milling cutter. When it is necessary to correct the installation of the milling cutter, the cross cap 9-2 can be rotated by a tool such as a screwdriver. The cross cap 9-2 drives the threaded rod 9-1 to rotate, and the guide rod 9-4 provides a movable guide for the adjustment plate 9-3, so that the adjustment plate 9-3 can adjust the extrusion state of the milling cutter, thereby achieving the installation correction of the milling cutter.

[0034] Compared with the prior art, the beneficial effects of the present invention are:

[0035] Through the cooperation of the correction adjustment mechanism 9, the installation of the milling cutter can be corrected and adjusted to ensure that the milling cutter can have a higher installation accuracy on the milling cutter seat;

[0036] Through the cooperation of the clamping cylinder 3, the expansion joint 4, the spring 5, the extrusion block 6, the inclined mouth 7 and the internal thread locking cover 8, not only can the milling cutter be stably clamped and fixed, but the disassembly and assembly process of the milling cutter is also very convenient.

[0037] For those skilled in the art, they can modify the technical solutions described in the aforementioned embodiments and make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the scope of protection of the present utility model.
