[0026] 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.

[0027] Embodiment 1:

[0028] See also Figure 1 - Figure 4 As shown, a quick-loading and unloading fixture for a milling machine comprises:

[0029] Milling machine 1;

[0030] A fine-tuning assembly 2 is arranged at one side of the top of the milling machine 1. The fine-tuning assembly 2 includes an adjustment frame 21 movably installed above the milling machine 1, an adjustment plate 22 is movably installed inside the adjustment frame 21, and a clamping assembly 3 is fixedly installed at the top of the adjustment plate 22;

[0031] The disassembly and assembly component 4 is arranged on one side of the milling machine 1. The disassembly and assembly component 4 includes two U-shaped frames 44 fixedly installed at the top of the milling machine 1. Locking plates 48 are movably installed inside the two U-shaped frames 44. Locking blocks 41 are symmetrically installed on both sides of the adjustment frame 21. The locking blocks 41 are provided with locking holes 43 on one side close to the U-shaped frames 44, and the locking holes 43 are correspondingly arranged with the locking plates 48.

[0032] Specifically, the clamping assembly 3 includes a clamping frame 31, a first threaded rod 32, a threaded block 33, and a clamping plate 35. The clamping frame 31 is fixedly installed on one side of the top end of the adjusting plate 22. The first threaded rod 32 is movably installed inside the clamping frame 31 through a bearing. Two threaded blocks 33 are installed on the outside of the first threaded rod 32 through threaded engagement. The two threaded blocks 33 are both slidably fitted with the inner wall of the clamping frame 31. The internal threads of the two threaded blocks 33 are opposite. A servo motor 34 is installed on one side of the outside of the clamping frame 31 through a fixed seat. The output end of the servo motor 34 is connected to the shaft of the first threaded rod 32 through a coupling. The clamping plate 35 is fixedly installed on the side of the two threaded blocks 33 away from the clamping frame 31.

[0033] As can be seen from the above, the first threaded rod 32 can drive the two threaded blocks 33 to move inside the clamping frame 31 by rotating. Since the internal threads of the two threaded blocks 33 are opposite, when the first threaded rod 32 rotates, the two threaded blocks 33 will move toward or away from each other, thereby driving the two clamping plates 35 to move closer to or away from each other, so that the workpiece can be clamped by the clamping plates 35, and the servo motor 34 provides power output for the rotation of the first threaded rod 32.

[0034] Specifically, the adjustment plate 22 is slidably fitted with the inner wall of the adjustment frame 21, and a No. 2 threaded rod 23 is installed inside the adjustment plate 22 through threaded engagement. One end of the No. 2 threaded rod 23 is movably installed on one side of the inner wall of the adjustment frame 21 through a bearing, and a handwheel 24 is movably installed on the outside of the adjustment frame 21 near the side of the No. 2 threaded rod 23. The handwheel 24 is connected to the shaft of the No. 2 threaded rod 23 through transmission. Limiting grooves 25 are symmetrically provided on both sides of the adjustment frame 21, and limiting blocks 26 are movably installed inside the limiting grooves 25. The limiting blocks 26 are fixedly connected to the adjustment plate 22 near the inner side of the adjustment frame 21.

[0035] As can be seen from the above, by setting the clamping assembly 3 above the adjusting plate 22, the movable adjusting plate 22 is used to drive the entire clamping assembly 3 to move forward and backward, so that the clamping assembly 3 drives the workpiece closer to or away from the milling cutter, so as to achieve fine-tuning of the distance between the workpiece and the milling cutter. The limit block 26 and the limit groove 25 can limit the adjusting plate 22 so that the direction of the adjusting plate 22 will not deviate during the movement.

[0036] Embodiment 2:

[0037] See also Figure 1 and Figure 3 - Figure 4 As shown, locking blocks 41 are symmetrically installed on both sides of the adjustment frame 21, a pull plate 42 is fixedly installed on the top of the locking block 41, a locking hole 43 is opened on the side of the locking block 41 away from the adjustment frame 21, a U-shaped frame 44 is fixedly installed on the top of the milling machine 1 close to the locking block 41, and stop blocks 45 are symmetrically installed on both sides of the U-shaped frame 44, and a stop groove 46 is opened on the side of the locking block 41 close to the stop block 45, and the stop block 45 slides and fits with the inner wall of the stop groove 46.

[0038] Specifically, a support plate 47 is fixedly installed inside the U-shaped frame 44, and a locking plate 48 is movably installed between the support plate 47 and the U-shaped frame 44 through a slot. The locking plate 48 extends into the locking hole 43 on the side close to the locking block 41, and the locking plate 48 slides in contact with the inner wall of the locking hole 43. The locking plate 48 is provided with an arc surface on the side close to the locking block 41, and a reset plate 49 is fixedly installed on the outer side of the locking plate 48. Two reset springs 410 are connected between the reset plate 49 and the inner wall of the U-shaped frame 44, and the two reset springs 410 are symmetrically arranged on both sides of the locking plate 48.

[0039] As can be seen from the above, the pull plate 42 is convenient for lifting the entire device during installation and disassembly, the locking hole 43 cooperates with the locking plate 48 to achieve rapid disassembly and assembly of the entire device on the milling machine 1, the block 45 and the retaining groove 46 can position the adjustment frame 21, so that the locking hole 43 and the locking plate 48 are aligned during installation, and the reset plate 49 and the reset spring 410 can drive the locking plate 48 to complete the reset.

[0040] When in use, it is only necessary to lift the pull plate 42 and then press the blocking groove 46 along the outer wall of the block 45. During the pressing process, the edge of the locking block 41 will squeeze the arc surface of the locking plate 48, and then the locking plate 48 will move inside the U-shaped frame 44. At the same time, the reset spring 410 will be squeezed until the locking block 41 is completely pressed down, the locking hole 43 will correspond to the position of the locking plate 48, and then the locking plate 48 will extend into the locking hole 43 under the action of the reset spring 410. At this time, the installation of the overall structure is completed. When disassembly is required, it is only necessary to pull the locking plate 48 to both sides to make the locking plate 48 away from the locking hole 43. At this time, the pulling plate 42 can be used to lift the overall structure to complete the disassembly work.

[0041] 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.
