Description

Technical Field

[0001] The utility model relates to the technical field of fixture devices, and more specifically, the utility model relates to a fixture for a numerical control machine tool. Background Art

[0002] A numerical control machine tool is a program-controlled automated machine tool that can quickly process parts with the same specifications through a program, and has the advantages of high precision and fast processing speed. The fixture for a numerical control machine tool is an important positioning device, and the processing precision of a numerical control machine tool mainly depends on the precise positioning of the fixture. The fixture mainly includes a workpiece fixture and a tool fixture. The workpiece fixture of a traditional numerical control machine tool is composed of components such as a support plate, a clamping block, and a threaded rod. The workpiece is placed on the support plate, and the position of the clamping block is adjusted through the threaded rod to position the workpiece. However, the traditional fixture for a numerical control machine tool can only clamp the workpiece in the horizontal direction. If the clamped part of the workpiece is relatively thin, the clamping strength is insufficient when the fixture clamps the workpiece, which affects the clamping precision of the workpiece to a certain extent, and the clamping precision adjusted by the threaded rod alone is not fine enough. To solve the deficiencies of the prior art, we propose a fixture for a numerical control machine tool. Summary of the Utility Model

[0003] To overcome the above-mentioned defects of the prior art, the utility model provides a fixture for a numerical control machine tool to solve the problems that the traditional fixture for a numerical control machine tool can only clamp the workpiece in the horizontal direction, if the clamped part of the workpiece is relatively thin, the clamping strength is insufficient when the fixture clamps the workpiece, which affects the clamping precision of the workpiece to a certain extent, and the clamping precision adjusted by the threaded rod alone is not fine enough.

[0004] To solve the above technical problems, the utility model provides the following technical solution: A fixture for a numerical control machine tool, including a base, a workpiece is arranged above the base, a clamping assembly is arranged on one side of the workpiece, and an auxiliary assembly is arranged on one side of the clamping assembly;

[0005] The clamping assembly includes a support plate fixedly installed on the top surface of the base. A first slide rail is provided on the top surface of the support plate, and a second slide rail is provided on the bottom surface of the support plate. The support plate is slidably connected with a clamping block through the first slide rail. A first threaded rod is rotatably connected to the inner wall of the clamping block. The top end of the first threaded rod is fixedly connected with a first knob. The bottom end of the first threaded rod is rotatably connected with a pressing plate, and the bottom surface of the pressing plate is in contact with the workpiece. The support plate is slidably connected with two third slide rails through the second slide rail. A fixed shaft is fixedly connected to the top of the base, and the fixed shaft is located below the center of the support plate. An X-shaped folding frame is rotatably connected to the outer wall of the fixed shaft. Four sliding rods are fixedly connected to the four corners of the X-shaped folding frame, and the X-shaped folding frame is slidably connected with the two third slide rails through the four sliding rods. A second threaded rod is rotatably connected to the outer surface of one side of one of the third slide rails, and the second threaded rod is threadedly connected with the support plate. One end of the second threaded rod is fixedly connected with a second knob.

[0006] Among them, there are two clamping blocks, first threaded rods, first knobs and pressing plates, which are symmetrically distributed on the left and right sides of the workpiece. The two third slide rails are respectively fixedly connected with the two clamping blocks.

[0007] Among them, the two third slide rails are symmetric about the axis of the fixed shaft. The X-shaped folding frame is composed of two identical and intersecting connecting rods, and the two connecting rods can rotate relative to the fixed shaft.

[0008] The auxiliary assembly includes a material box fixedly installed on the top of the base. An air suction pipe is fixedly connected to the outer surface of one side of the material box. An electric push rod is fixedly connected to the top of the inner cavity of the material box. One end of the push rod of the electric push rod is fixedly connected with a right-angled trapezoidal hammer. A sliding door is arranged on the outer surface of one side of the material box.

A filter screen and a motor are fixedly installed on the inner wall of the air outlet pipe, the motor is located in front of the filter screen, and one end of the rotating shaft of the motor is fixedly connected with a fan.

[0009] Among them, the inner cavity of the material box is a right-angled trapezoidal space. When the right-angled trapezoidal hammer descends, the bottom surface of the right-angled trapezoidal hammer is in contact with the bottom surface of the inner cavity of the material box.

[0010] Among them, the air inlet of the air suction pipe is located on one side of the workpiece.
