Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mechanical processing, in particular to an anti-loosening milling cutter seat. Background Art
[0002] A CNC deburring machine is a machine used to efficiently remove burrs, nozzles, parting lines, ejectors, and flash from the surface of die-cast parts. This equipment typically includes a cast iron base, a cutter head, a cradle, and an electronic control system. It can perform milling, pinning, grinding, and polishing to achieve processing of various surfaces and shapes. Through automated and mechanized solutions, the quality and efficiency of deburring are improved, while reducing reliance on manual operations, ensuring product processing quality, improving production efficiency, and reducing manufacturing costs.
[0003] In order to meet different processing needs and process requirements, a milling cutter holder is usually installed on the cutter head. By installing milling cutters or drill bits and other tools on the milling cutter holder, burrs and excess materials on the workpiece are removed. The electric spindle on the cutter head used to drive the milling cutter to rotate can adjust the rotation direction according to the specific processing conditions, so as to better handle the burrs on the workpiece. However, when the rotation direction of the electric spindle is the same as the thread direction of the nut fixing the milling cutter, the internal and external threads will cause relative rotation in the direction of loosening the nut. At the same time, the vibration during the milling process may loosen the nut fixing the milling cutter, which may cause the milling cutter to fall off and cause danger. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model aims to provide an anti-loosening milling cutter seat.
[0005] The purpose of the utility model can be achieved through the following technical solutions: an anti-loosening milling cutter seat, comprising a mounting seat, a tool sleeve rotatably arranged on the mounting seat, a tapered hole for mounting the milling cutter at the end of the tool sleeve, a pressure cap being threadedly connected to the outer side of the tapered hole, and a clamping sleeve for clamping the pressure cap being movably provided on the tool sleeve.
[0006] Preferably, grooves are provided at intervals along the circumference of the pressing cap, and protrusions that cooperate with the grooves are provided at the bottom of the ferrule.
[0007] Preferably, the circumferential surface of the tool sleeve is provided with a first plane in the axial direction, and the inner wall of the clamping sleeve is provided with a second plane matching the first plane.
[0008] Preferably, a retaining ring is provided on the knife sleeve, and a retaining groove corresponding to the retaining ring is provided on the clamping sleeve.
[0009] Preferably, a spring seat is provided on the knife sleeve above the clamping sleeve, and a spring is provided between the spring seat and the clamping sleeve.
[0010] The beneficial effects of the utility model are as follows: a movable clamping sleeve is provided on the tool sleeve to clamp the pressure cap, thereby preventing the pressure cap from loosening and causing the milling cutter to fall off, effectively improving the safety of use, and having a simple structure, easy use and low cost.

[0017] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), such directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0018] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.
[0019] The following will be combined with specific embodiments to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.
[0020] See Figures 1 to 4 As shown, the structure of the utility model is: an anti-loosening milling cutter seat, comprising a mounting seat 1, a tool sleeve 2 rotatably set on the mounting seat 1, the tool sleeve 2 is installed on the electric spindle through the mounting seat 1, and is connected to the rotating shaft of the electric spindle through a coupling, a chuck milling cutter is installed in the tapered hole 3, and then the milling cutter is locked by a pressure cap 4 connected to the outer thread of the tapered hole 3, and then the pressure cap 4 is clamped by a clamping sleeve 5 movably provided on the tool sleeve 2 to prevent the pressure cap 4 from loosening and causing the milling cutter to fall off, and the clamping sleeve 5 can move up and down along the tool sleeve 2. When loading or unloading the tool, the clamping sleeve 5 is moved up so that the pressure cap 4 can be rotated to load and unload the milling cutter.
[0021] like Figure 4 As shown, grooves 6 are provided on the pressing cap 4 at intervals in the circumferential direction, and protrusions 7 that cooperate with the grooves 6 are provided at the bottom of the ferrule 5. Specifically, the ferrule 5 clamps the grooves 6 on the pressing cap 4 through the protrusions 7 at the bottom to prevent the pressing cap 4 from loosening.
[0022] like Figure 3 As shown, the circumferential surface of the tool sleeve 2 is provided with a first flat surface 8 in the axial direction, and the inner wall of the ferrule 5 is provided with a second flat surface that cooperates with the first flat surface 8. Specifically, through the cooperation between the first flat surface 8 and the second flat surface, it is ensured that the ferrule 5 can move axially along the tool sleeve 2 while the ferrule 5 can rotate with the tool sleeve 2.
[0023] like Figure 2 As shown, a retaining ring 9 is provided on the knife sleeve 2, and a clamping groove 12 corresponding to the retaining ring 9 is provided on the clamping sleeve 5. The retaining ring 9 is used to clamp the clamping groove 12 when the pressure cap 4 is removed to prevent the clamping sleeve 5 from falling off.
[0024] like Figure 1 、 Figure 2 As shown, a spring seat 10 is provided on the tool sleeve 2 above the clamping sleeve 5, and a spring 11 is provided between the spring seat 10 and the clamping sleeve 5. Specifically, under the action of the spring 11, the protrusion 7 at the bottom of the clamping sleeve 5 is always stuck in the groove 6 on the pressure cap 4, preventing the protrusion 7 from detaching from the groove 6 during the rotation of the tool sleeve 2.
[0025] During specific use, first use the chuck milling cutter to install it in the tapered hole 3, then lock the milling cutter by connecting the pressure cap 4 to the outer side of the tapered hole 3 through the threaded connection, and then clamp the pressure cap 4 through the movably arranged sleeve 5 on the tool sleeve 2 to prevent the pressure cap 4 from loosening and causing the milling cutter to fall off. The sleeve 5 can move up and down along the tool sleeve 2. When installing or removing the tool, the sleeve 5 is moved up so that the sleeve 5 no longer clamps the pressure cap 4, so that the milling cutter can be installed and unloaded.
[0026] The above further describes the present invention with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the present invention. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the present invention.
