[0035] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0036] Example:

[0037] See also Figure 1-Figure 3 A fixing seat for alloy milling cutter processing includes a housing 1, a pressing block 2, a driving ring 3, a motor 4 and a screw 5. The housing 1 is a cylindrical hollow structure, one end of which is a closed structure, and the middle of the other end has a circular clamping opening 6, and the axis of the clamping opening 6 is colinear with the axis of the housing 1. In addition, the housing 1 can be installed on the spindle of a milling machine, and the spindle of the milling machine drives the housing 1 to rotate around its axis.

[0038] At least three pressing blocks 2 are arranged in the housing 1. In this embodiment, three pressing blocks 2 are taken as an example for description.

[0039] The three pressing blocks 2 are evenly distributed around the axis of the shell 1, with one side of the three pressing blocks 2 close to the axis of the shell 1 and the other side extending toward the inner wall of the shell 1. In addition, the side of the pressing block 2 close to the inner wall of the shell 1 is an inclined surface structure, so that the pressing block 2 is a triangular structure. Among them, the wider end of the pressing block 2 is close to the clamping opening 6.

[0040] The drive ring 3 is movably arranged in the housing 1, and the axis of the drive ring 3 is colinear with the axis of the housing 1, and the drive ring 3 can make reciprocating linear motion along the axis of the housing 1. The inner wall of the drive ring 3 is in sliding contact with the side of the inclined surface of the pressure block 2. In addition, the drive ring 3 is also provided with a threaded hole, and the axis of the threaded hole is parallel to the axis of the drive ring 3.

[0041] A screw rod 5 is matched in the screw rod 5 hole. One end of the screw rod 5 is rotatably connected to the inner wall of the housing 1 , and the other end is coaxially connected to an output shaft of a motor 4 .

[0042] During operation, the alloy milling cutter to be clamped is inserted into the shell 1 from the clamping port 6. At this time, all the pressure blocks 2 are distributed around the alloy milling cutter, and then the screw 5 is driven to rotate by the motor 4, so that the drive ring 3 makes a linear motion in the shell 1 through the threaded cooperation of the screw 5 and the drive ring 3, and then the drive ring 3 moves on the inclined surface of the pressure block 2 through the sliding contact between the drive ring 3 and the pressure block 2, so that all the pressure blocks 2 move closer to each other, thereby clamping the alloy milling cutter.

[0043] In this technical solution, it is only necessary to place the alloy milling cutter in the clamping port 6 and start the motor 4 to complete the clamping of the alloy milling cutter. When the alloy milling cutter needs to be removed, it is only necessary to control the motor 4 to flip. Compared with the prior art, this solution has the advantage of convenient and quick clamping and disassembly of the alloy milling cutter.

[0044] In one specific embodiment:

[0045] The fixing seat also includes an inner liner 7, a guide rod 8 and a spring 9. Specifically, the inner liner 7 is arranged in the housing 1, and the inner liner 7 is also a hollow cylindrical structure, both ends of the inner liner 7 are open structures, and one end of the inner liner 7 is fixed inside one end of the housing 1 having a clamping opening 6.

[0046] The inner liner 7 is coaxially arranged with the shell 1, and there is a distance between the outer wall of the inner liner 7 and the inner wall of the shell 1. At the same time, 6 through holes are arranged outside the inner liner 7. A guide rod 8 is movably arranged in each through hole of the inner liner 7.

[0047] One end of the guide rod 8 is fixedly arranged on the side of the inclined surface of the pressing block 2, and a guide rod 8 is respectively arranged on both ends of the pressing block 2. A spring 9 is sleeved on each guide rod 8, one end of the spring 9 is fixedly connected to the end of the guide rod 8 away from the pressing block 2, and the other end of the spring 9 abuts against the outer wall of the inner container 7.

[0048] In this embodiment, the movement path of the pressing block 2 can be limited by providing the inner liner 7 and the guide rod 8. By providing the spring 9, during the process of unloading the alloy milling cutter, the driving block moves toward the smaller end of the pressing block 2, and the spring 9 drives all the pressing blocks 2 to move away from each other.

[0049] Preferably, a guide rod 8 is provided at both ends of each pressing block 2, and the driving ring 3 is located between the two guide rods 8 on the same pressing block 2. In addition, a plurality of limiting holes can be provided on the driving ring 3, and a plurality of limiting rods can be provided in the inner tank 7, and the limiting rods are passed through the limiting holes, so that the movement trajectory of the driving block is only in the direction of the line.

[0050] In another specific embodiment:

[0051] See also Figure 2and Figure 4 The fixing seat further includes an L-shaped bracket 10, a contact rod 11, a first magnetic block 12, a second magnetic block 13 and a U-shaped frame 14. Specifically, both ends of the U-shaped frame 14 are fixedly arranged on the inner wall of the inner tank 7, and the middle of the U-shaped frame 14 has two metal contacts, and the two metal contacts are connected to the two motor 4 electrodes of the motor 4 through wires.

[0052] One end of the L-shaped bracket 10 is arranged on the inner wall of the inner tank 7, and the L-shaped bracket 10 is located in the middle of the U-shaped bracket, and the other end of the L-shaped bracket 10 extends in a direction parallel to the screw 5. At the same time, this end of the L-shaped bracket 10 is located in the middle of the U-shaped frame 14, and this end of the L-shaped bracket 10 has two movable holes.

[0053] A touch rod 11 is slidably disposed in each of the two movable holes of the L-shaped bracket 10, and a first magnetic block 12 is disposed at one end of the touch rod 11 close to the inner wall of the inner container 7. A second magnetic block 13 is disposed on the inner wall of the inner container 7 and is located on the inner side of the U-shaped bracket 14 and close to the first magnetic block 12. The second magnetic block 13 has the same magnetic pole on the side opposite to the first magnetic block 12.

[0054] In addition, the two contact rods 11 are electrically connected to devices for controlling the forward or reverse rotation of the motor 4 .

[0055] In this embodiment, when the spindle of the milling machine rotates in the driving housing 1, the second magnetic block 13 moves in the direction close to the first magnetic block 12 under the influence of centrifugal force, and the end of the touch rod 11 is separated from the contact point, and the motor 4 is powered off. Through this technical solution, the problem of accidentally touching the device that controls the rotation of the motor 4 during the milling machine processing, which causes damage to the alloy milling cutter, can be avoided.

[0056] When the entire milling machine is stopped, the second magnetic block 13 and the first magnetic block 12 are in a state where the same magnetic poles are opposite to each other. At this time, the first magnetic block 12 is repelled by the second magnetic block 13, causing the feeler rod 11 to contact the contact point, thereby energizing the motor 4 and allowing it to be controlled.

[0057] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
