After retrieval, in the prior art (publication number: CN202321563338.9), a fixture for a numerical control milling machine for processing thin plate parts is described. It is recorded that "rotating the first threaded adjusting rod, the first threaded adjusting rod can drive the chuck to extend or retract in the faucet, and in this way, the size between the faucets is adjusted. And the support arm is affected by the movable seat, so that it can only move at a fixed point.

However, in the prior art, there is a problem that it is difficult to tightly press thin plate parts with inconsistent thicknesses on the milling machine when the chucks at both ends of the support arm press down simultaneously. Content of the Utility Model

[0003] In order to overcome the defects existing in the prior art, a numerical control milling machine convenient for clamping and positioning is provided at present to solve the problem that it is difficult to tightly press thin plate parts with inconsistent thicknesses on the milling machine when the chucks at both ends of the support arm press down simultaneously in the prior art.

The upper end surface of the independent pressing block is connected with a pressure sensor at the lower end surface of an adjusting block through a spring. The upper end of the adjusting block is connected with the lower pressing plate through an adjusting screw. The pressure sensor is electrically connected with a pressure monitor.

[0006] Further, a machine base is arranged at the lower end of the milling machine workbench, a numerical control panel is arranged at the right end of the milling machine workbench, and the pressure monitor is fixedly installed on the front surface of the body of the milling machine workbench.

[0007] Further, the upper end of the alignment clamping plate is connected with a screw rod through a driving block, and a motor transmission mechanism is axially connected to the rear side of the screw rod; and the motor transmission mechanism is installed on the rear side body surface of the milling machine workbench.

[0008] Further, electric push rods are symmetrically fixed on the upper surface of the alignment clamping plate, the lower pressing plate is connected in the side groove of the alignment clamping plate, and three groups of independent pressing blocks are equidistantly distributed at the lower end of the lower pressing plate.

[0018] Refer to Figures 1 to 4As shown in the figure, the utility model provides a numerical control milling machine which is convenient for clamping and positioning, including: a milling machine workbench 1, alignment clamping plates 2 and a milling equipment 3. The alignment clamping plates 2 are symmetrically distributed on the upper surface of the milling machine workbench 1, and the milling equipment 3 is installed on the upper end body of the milling machine workbench 1.

[0019] On the side of the alignment clamping plate 2, a lower pressing plate 4 is connected through an electric push rod 22. An independent pressing block 5 is inserted and limited in the lower end groove surface of the lower pressing plate 4. The upper end surface of the independent pressing block 5 is connected to the pressure sensor 45 on the lower end surface of the adjusting block 42 through a spring 52. The upper end of the adjusting block 42 is connected to the lower pressing plate 4 through an adjusting stud 44. The pressure sensor 45 is electrically connected to a pressure monitor 41.

[0020] During use, place the part on the surface of the milling machine workbench 1, drive the screw rod 23 to make the alignment clamping plate 2 clamp the part, and then move the lower pressing plate 4 downward so that the lower pressing plate 4 presses on the surface of the part. When the pressure monitor 41 monitors that among multiple groups of pressure values, a few values are inconsistent, control the indicator light 43 at the corresponding inconsistent value to light up, so that the processing personnel rotate the adjusting stud 44 to drive the independent pressing block 5 to press down or move up, so that the independent pressing block 5 presses down tightly or reduces the pressing force upward, ensuring the balance of the clamping force of the numerical control milling machine on the part.

[0021] In this embodiment, a machine base 11 is provided at the lower end of the milling machine workbench 1, a numerical control panel 12 is provided at the right end of the milling machine workbench 1, and the pressure monitor 41 is fixedly installed on the front surface of the body of the milling machine workbench 1.

[0022] As a preferred implementation method, the numerical control panel 12 is used to control the milling process of the milling equipment 3. The pressure monitor 41 is convenient for receiving multiple groups of pressure values and finding the independent pressing block 5 at the position where the value is inconsistent with the majority of values.

[0023] In this embodiment, the upper end of the alignment clamping plate 2 is connected to a screw rod 23 through a driving block 21, and the screw rod 23 is axially connected to a motor transmission mechanism 24 at the rear; and the motor transmission mechanism 24 is installed on the rear surface of the body of the milling machine workbench 1. Electric push rods 22 are symmetrically fixed on the upper surface of the alignment clamping plate 2 left and right. The lower pressing plate 4 is connected in the side groove of the alignment clamping plate 2, and three groups of independent pressing blocks 5 are equally distributed at the lower end of the lower pressing plate 4.

[0024] As a preferred implementation method, the motor transmission mechanism 24 drives two groups of screw rods 23 to rotate, so that the driving blocks 21 on the surface of the screw rods 23 drive the alignment clamping plates 2 to move synchronously and in opposite directions, facilitating clamping the part on the surface of the milling machine workbench 1 in the middle. The three groups of independent pressing blocks 5 at the lower end of the lower pressing plate 4 can adjust the pressing force accordingly for parts with different local thicknesses.

[0025] In this embodiment, a warning lamp 43 is mounted on the upper surface of the lower pressing plate 4; and the warning lamp 43 is located adjacent to the adjusting stud 44. A rubber pad 51 is adhesively bonded to the lower surface of the independent pressing block 5. A pressure sensor 45 is embedded and installed on the lower surface of the adjusting block 42; and the spring 52 is located between the pressure sensor 45 and the independent pressing block 5.

[0026] As a preferred implementation manner, the warning lamp 43 is convenient for indicating the position of the pressure sensor 45 whose pressure value is inconsistent with multiple groups of pressure values, facilitating the processing personnel to quickly locate and adjust the pressure of which independent pressing block 5. When the independent pressing block 5 presses down on the surface of the part, the upward extrusion force of the spring 52 is the pressure of the independent pressing block 5 detected by the spring 52.

[0027] In this embodiment, the alignment clamping plate 2, the electric push rod 22, the lower pressing plate 4, the adjusting block 42, the pressure sensor 45, the adjusting stud 44 and the independent pressing block 5 constitute the balanced clamping mechanism of the milling machine table 1.

[0029] The CNC milling machine with convenient clamping and positioning of the present utility model can effectively solve the problem in the prior art that it is difficult to tightly clamp the thin plate parts with inconsistent thicknesses on the milling machine when the chucks at both ends of the support arm press down simultaneously, facilitating the fixture of the CNC milling machine to independently adjust the clamping force, avoiding the deformation phenomenon caused by different clamping forces during the synchronous positioning and clamping of thin plate parts, ensuring the balance of the clamping force of the CNC milling machine on the parts, facilitating the CNC milling machine to quickly and stably clamp and position thinner parts, improving the processing quality of the CNC milling machine, and being applicable to the CNC milling machine with convenient clamping and positioning.
