[0022] 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.

[0023] Reference Figure 1 , Figure 3 and Figure 4 The utility model provides an embodiment: a high-efficiency workpiece clamp for a milling machine, comprising a processing table 1, two support rods 8 are fixedly connected to one side of the top of the processing table 1, and the tops of the two support rods 8 are rotatably connected to a support plate 10, and the left and right sides of the top of the support plate 10 are fixedly connected to fixed blocks 12, and a limiting groove 13 is provided inside the fixed block 12, and a limiting plate 15 is slidably connected inside the limiting groove 13, and a pull rod 18 is fixedly connected to one side of the limiting plate 15, and a spring 14 is sleeved on the outer side of the pull rod 18, and a slot 17 is fixedly connected to the other side of the spring 14, and a three-jaw chuck 11 is slidably connected to the top of the support plate 10, and the left and right sides of the three-jaw chuck 11 are provided with slots 17, and an angle adjustment component is provided at the bottom of the support plate 10.

[0024] The two support rods 8 are fixed by the processing table 1, and then the two support rods 8 can support one end of the support plate 10, so that the support plate 10 can rotate along one end, and the two fixed blocks 12 are fixed by the support plate 10, so that the limit groove 13 opened inside the fixed block 12 can limit the movement of the limit plate 15, and the limit plate 15 can be driven to move by pulling the pull rod 18, and pressure is applied to the spring 14, so that the clamping block 16 can be driven by the limit plate 15 to disengage from the clamping groove 17, so as to realize the disassembly operation of the three-jaw chuck 11, wherein the function of the spring 14 is that when the three-jaw chuck 11 is installed, the elastic potential energy can be released after the pull rod 18 is loosened, so as to push the limit plate 15 to move, so that the clamping block 16 enters the clamping groove 17 to complete the plug-in fit, so as to realize the fixation of the three-jaw chuck 11, and the clamp is fixed by clamping, which is convenient for disassembly and replacement, and convenient for later use and maintenance, and the inclination angle adjustment of the clamp is realized by the angle adjustment component, thereby improving the flexibility of use of the clamp.

[0025] Reference Figure 1 and Figure 2 The angle adjustment component includes two slide grooves 3, which are respectively opened on the front and rear sides of the top of the processing table 1. The front slide groove 3 is rotatably connected to a threaded rod 4, and the threaded rod 4 is externally threadedly connected to a threaded block 5. The rear slide groove 3 is fixedly connected to a slide rod 6, and the slide rod 6 is slidably connected to a slider 7. The outsides of the threaded block 5 and the slide rod 6 are both rotatably connected to a connecting rod 9. The outside of the processing table 1 is fixedly connected to a motor 2, and the other end of the threaded rod 4 passes through the outer wall of the processing table 1 and is fixedly connected to the output end of the motor 2. The threaded block 5 is slidably connected to the inner wall of the front slide groove 3, and the slider 7 is slidably connected to the inner wall of the rear slide groove 3. The other ends of the two connecting rods 9 are rotatably connected to the top of the support plate 10.

[0026] Specifically, the motor 2 is fixed to the outside of the processing table 1 so that the motor 2 remains stable during operation, and the operation of the motor 2 can drive the threaded rod 4 to rotate, so that the threaded block 5 moves inside the front slide groove 3, and at the same time, the slider 7 slides inside the rear slide groove 3 along the direction of the slide rod 6, wherein the two slide grooves 3 respectively limit the threaded block 5 and the slider 7, so that the two remain stable during movement, thereby simultaneously pushing the connecting rod 9 to move, and the two connecting rods 9 are rotatably connected to the bottom of the support plate 10 to support it, thereby changing the horizontal inclination angle of the support plate 10, realizing the angle adjustment of the three-jaw chuck 11, and placing the workpiece in the optimal processing position through angle adjustment, thereby improving the processing accuracy and surface quality.

[0027] Reference Figure 4One end of the spring 14 is fixedly connected to the outside of the limiting plate 15, and the other end of the spring 14 is fixedly connected to the inner wall of the limiting groove 13. One end of the pull rod 18 passes through the outer wall of the fixed block 12, and the outside of the pull rod 18 is slidably connected to the inside of the fixed block 12. The cross-section of the clamping block 16 is set to be square, and the outside of the clamping block 16 is slidably connected to the inside of the clamping groove 17.

[0028] Specifically, the two ends of the spring 14 are respectively fixed on one side of the limit plate 15 and the inside of the limit groove 13, so that the spring 14 will not be misplaced when it is extended and retracted by external force, thereby ensuring the stability of the structure operation. The limit plate 15 can be driven to move through the pull rod 18, and then the disassembly operation of the clamp is realized. The cross-section of the block 16 is set to be square, so that the block 16 is more secure when it is plugged into the slot 17, and the installation of the three-jaw chuck 11 is more stable. At the same time, the clamp will not shake during fine milling after clamping the workpiece.

[0029] Reference Figure 1 A finishing milling mechanism 19 is installed at the top rear end of the processing table 1.

[0030] Specifically, the precision milling mechanism 19 can be used to perform precision milling on the clamped workpiece, thereby facilitating subsequent use.

[0031] Working principle: When using this clamp, you can first pull the pull rod 18 on the outside of the two fixed blocks 12, and use the pull rod 18 to drive the limit plate 15 to slide inside the limit groove 13, so that the limit plate 15 applies pressure to the spring 14 to make it contract. At the same time, the limit plate 15 drives the card block 16 to disengage from the card slot 17, so that the three-jaw chuck 11 can be removed, and the three-jaw chuck 11 can be disassembled, replaced or repaired. When installing, you only need to repeat the above steps. After placing the three-jaw chuck 11, release the pull rods 18 on both sides, and the spring 14 releases the elastic potential energy to push the limit plate 15 to move, so that the card block 16 enters the inside of the card slot 17 to complete the plug-in fit, and fixes the three-jaw chuck 11. The clamp is fixed by card connection, which is convenient for disassembly and replacement, and convenient for later use and maintenance.

[0032] After the workpiece is clamped, the threaded rod 4 can be driven to rotate by the operation of the motor 2, so that the threaded block 5 moves inside the front slide groove 3, and then the slider 7 slides inside the rear slide groove 3 along the direction of the slide rod 6, thereby pushing the connecting rod 9 to move, so that the horizontal inclination angle of the support plate 10 changes, and the angle adjustment of the three-jaw chuck 11 is realized. Through the angle adjustment, the workpiece is placed in the best processing position, and the processing accuracy and surface quality are improved.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
