[0018] Please refer to the attached drawings of the specification Figures 1 - 5, a drilling fixture for metal part processing, comprising a base 1 and four groove fixing blocks 4 fixed at the four top corners of the base 1. A hydraulic cylinder 5 is embedded in the upper side of the groove fixing block 4. A fixing ring 51 is sleeved on one side of the hydraulic cylinder 5. A push plate 52 is fixed on one side of the fixing ring 51. A fixing column 22 is fixed on one side of the two push plates 52. A curved surface push plate 21 is fixed at one end of the fixing column 22. A support column 61 is fixed on one side of the other two push plates 52. A rectangular hole 611 is provided in the support column 61. A small screw rod 64 is provided in the rectangular hole 611. A first fixing block 62 is provided at the bottom end of the small screw rod 64. A fixing screw 63 is provided on the first fixing block 62. A second fixing block 65 is fixed at the top end of the small screw rod 64. An upper clamping plate 32 is fixed on one side of the second fixing block 65. A lower clamping plate 31 is fixed on one side of the support column 61. Threaded holes 311 are provided on both sides of the lower clamping plate 31 and the upper clamping plate 32. A screw rod 34 can be screwed into the threaded holes 311. A knob 35 is fixed at the top end of the screw rod 34. The screw rod 34 can be screwed into a nut 33.

[0019] In this embodiment, a drill fixture for machining metal parts is placed on the base 1. The first fixing block 62 and the fixing screw 63 are used to fix the small screw rod 64 to prevent the small screw rod 64 from falling. Pull the small screw rod 64 towards the edge side, and the small screw rod 64 drives the first fixing block 62, the second fixing block 65 provided thereon, and the fixing screw 63 sleeved thereon to move. The second fixing block 65 drives the upper clamping plate 32 to move; the groove fixing block 4 is located at the four top corners of the base 1 and is used to place the hydraulic cylinder 5. Open the two hydraulic cylinders 5, and the hydraulic cylinder 5 drives the fixing ring 51 sleeved thereon to push the push plate 52. The push plate 52 pushes the support column 61, and the support column 61 pushes the lower clamping plate 31 towards the center of the base. After reaching the appropriate position, place the metal part so that the edge of the metal part is located on the two lower clamping plates 31; remove the first fixing block 62, rotate the fixing screw 63 according to the height of the metal part, adjust the upper clamping plate 32 to be slightly higher than the metal part, and move the small screw rod 64 towards the center of the base. The small screw rod 64 drives the second fixing block 65 provided thereon and the fixing screw 63 sleeved thereon to move. The second fixing block 65 drives the upper clamping plate 32 to move. After moving to one end, rotate the fixing screw 63 to make the small screw rod 64 fall. The fall of the small screw rod 64 drives the second fixing block 65 and the upper clamping plate 32 to fall, so that the metal part is located between the upper clamping plate 32 and the lower clamping plate 31; the screw hole 311 and the screw rod 34 are in a state of being threadably connected. Rotate the four knobs 35 to make the screw rod 34 spiral downward through the screw holes 311 of the upper clamping plate 32 and the lower clamping plate 31, and make the screw rod 34 spiral into the nut 33 to complete the edge clamping of the metal part; in order to prevent incomplete vertical clamping of other special-shaped parts or deviation caused by the vibration of the drill press, this new type designs a horizontal clamping device 2. In the vertical direction, the curved surface push plate 21 is located above the lower clamping plate 31. After the vertical clamping device 3 completes the clamping, open the other two hydraulic cylinders 5. The hydraulic cylinder 5 drives the fixing ring 51 sleeved thereon to push the push plate 52. The push plate 52 pushes the fixed column 22 fixed thereon. The fixed column 22 pushes the curved surface push plate 21 fixed at one end thereof, and the two curved surface push plates 21 realize the clamping of the metal part in the horizontal diagonal direction.

[0020] In specific applications, pull the small screw rod 64 towards the edge side. The small screw rod 64 drives the first fixing block 62 and the second fixing block 65 provided thereon, as well as the fixing screw 63 sleeved thereon, to move. The second fixing block 65 drives the upper clamping plate 32 to move towards the edge side. Open the two hydraulic cylinders 5. The hydraulic cylinders 5 drive the fixing rings 51 sleeved thereon to push the push plate 52. The push plate 52 pushes the support column 61. The support column 61 pushes the lower clamping plate 31 towards the center of the base. After reaching the appropriate position, place the metal part so that the edge of the metal part is located on the two lower clamping plates 31. Remove the first fixing block 62. Rotate the fixing screw 63 according to the height of the metal part to adjust the upper clamping plate 32 to be slightly higher than the metal part. Move the small screw rod 64 towards the center of the base. The small screw rod 64 drives the second fixing block 65 and the fixing screw 63 sleeved thereon to move. The second fixing block 65 drives the upper clamping plate 32 to move. After moving to one end, rotate the fixing screw 63 to make the small screw rod 64 drop. The dropping of the small screw rod 64 drives the second fixing block 65 and the upper clamping plate 32 to drop, so that the metal part is located between the upper clamping plate 32 and the lower clamping plate 31. The screw hole 311 and the screw rod 34 are in a state where they can be screwed together. Rotate the 4 knobs 35 to make the screw rod 34 spiral downward through the screw holes 311 of the upper clamping plate 32 and the lower clamping plate 31, and make the screw rod 34 spiral into the nut 33 to complete the edge clamping of the metal part. In the vertical direction, the curved surface push plate 21 is located above the lower clamping plate 31. After the vertical clamping device 3 completes the clamping, open the other two hydraulic cylinders 5. The hydraulic cylinders 5 drive the fixing rings 51 sleeved thereon to push the push plate 52. The push plate 52 pushes the fixing column 22 fixed thereon. The fixing column 22 pushes the curved surface push plate 21 fixed at one end thereof. The two curved surface push plates 21 realize the clamping of the metal part in the horizontal diagonal direction.
