Embodiment 1

[0017] like figure 1 , figure 2 As shown, the milling machine square workpiece fixture includes a fixture seat, a slide rail 1, an adjusting screw 2, a moving block 3, and a clamping block 4. The lower end of the slide rail 1 is installed on the fixture seat, and the upper end of the slide rail 1 is stuck on the lower end of the moving block 3. On the concave edge, the lower end of the clamping block 4 is pressed on the upper end concave edge of the moving block 3, and the adjusting screw 2 is engaged with the moving block 3.

[0018] The clamping surface of the clamping block 4 is composed of four planes, the planes have the same size, and the angle between two adjacent planes is 90°. The length and width in the plane are 150mm; the clamping block 4 is inlaid with tungsten carbide-based hard alloy on its clamping surface.

Embodiment 2

[0020] like figure 1 , figure 2 As shown, the milling machine square workpiece fixture includes a fixture seat, a slide rail 1, an adjusting screw 2, a moving block 3, and a clamping block 4. The lower end of the slide rail 1 is installed on the fixture seat, and the upper end of the slide rail 1 is stuck on the lower end of the moving block 3. On the concave edge, the lower end of the clamping block 4 is pressed on the upper end concave edge of the moving block 3, and the adjusting screw 2 is engaged with the moving block 3.

[0021] The clamping surface of the clamping block 4 is composed of four planes, the planes have the same size, and the angle between two adjacent planes is 90°. The in-plane length and width of each are 130 mm; the clamping block 4 is inlaid with titanium carbonitride-based cemented carbide on its clamping surface.

Embodiment 3

[0023] like figure 1 , figure 2 As shown, the milling machine square workpiece fixture includes a fixture seat, a slide rail 1, an adjusting screw 2, a moving block 3, and a clamping block 4. The lower end of the slide rail 1 is installed on the fixture seat, and the upper end of the slide rail 1 is stuck on the lower end of the moving block 3. On the concave edge, the lower end of the clamping block 4 is pressed on the upper end concave edge of the moving block 3, and the adjusting screw 2 is engaged with the moving block 3.

[0024] The clamping surface of the clamping block 4 is composed of four planes with the same size. The angle between two adjacent planes on the clamping block 4 is 120°, and its length along the vertical direction of the front view is 210 mm. The length and width of the plane perpendicular to the vertical direction of the front view are both 190 mm; the clamping block 4 is inlaid with titanium carbonitride-based cemented carbide on its clamping surfac...

Abstract

The invention discloses a square workpiece fixture of a milling machine and belongs to the field of machine tool fixtures. The square workpiece fixture comprises a fixture base, a sliding rack, a regulation screw rod, a movable block and a clamping block, wherein the lower end of the sliding rack is arranged on the fixture base; the upper end of the sliding rail is clamped on the concave edge of the lower end of the movable block; the lower end of the clamping block is pressed on the concave edge of the upper end of the movable block; the regulation screw rod is meshed with the movable block; the clamping surface of the clamping block consists of four planes; the included angle of every two adjacent planes is identical with the angle of the corresponding outside corner of a square workpiece. The square workpiece fixture can be used for solving the problems such as high labor intensity, low workpiece lateral surface processing stability, long part processing auxiliary time, difficulty in clamping force control and the like caused by an existing general fixture, and has the advantages of simple structure, reasonable design, and easiness for manufacturing.

Description

technical field [0001] The invention belongs to the field of machine tool fixtures, and more specifically relates to a square workpiece fixture for milling machines. Background technique [0002] In the machinery manufacturing industry, lathes, especially milling machines, are widely used to process disc or shaft parts. When processing such parts, many parts need to use the end face or inner hole as the positioning clamping surface to perform cutting processes such as outer circle, end face, thread and axial cutting. For single-piece, small-batch, and large-volume workpiece processing, the positioning and clamping can generally be adjusted directly on the machine table to achieve positioning and clamping, and then the position of the part is determined by setting the processing coordinate system. For a certain batch of parts, it is necessary to reduce labor intensity, reduce part processing auxiliary time, and improve production efficiency by selecting relevant special fixt...
