Description

Technical Field

[0001] The utility model relates to the technical field of vertical milling machines, and more specifically to a milling fixture for vertical milling machines produced by metal shells. Background Art

[0002] Compared with horizontal milling machines, the main difference between vertical milling machines is that the spindle is arranged vertically. In addition to the different spindle arrangements, the worktable can be raised and lowered. The milling cutter used in vertical milling machines is relatively flexible and has a wider range of applications. When a vertical milling machine mills a metal shell, a fixture is required to fix it.

[0003] After searching, the utility model patent with announcement number CN215393905U discloses a milling fixture of a vertical milling machine for producing metal shells, including a fixing plate, and fixing mechanisms are arranged on both sides of the inner cavity of the shell, and the fixing mechanisms include a sliding rod, a sliding sleeve, a clamping rod and a through-port, one side of the outer wall of the two sliding sleeves is fixedly connected with a clamping rod, and the outer walls of the two clamping rods are slidably connected with through-ports, and the two through-ports are respectively opened on both sides of the top of the shell; the milling fixture of the vertical milling machine for producing metal shells, through the cooperation between the sliding rod, the sliding sleeve, the clamping rod and the through-port, makes the device connected by sliding between the clamping rod and the through-port when in use, so that when the two sliding sleeves move left and right toward each other, the two clamping rods can fix the metal shell on the top of the shell, and through this internal clamping method, the problem that most milling machine milling fixtures are fixed by external clamping method is solved, and when the metal shell adopts external clamping, the shell is easily deformed.

[0004] However, the above patents have the following shortcomings: when the metal shell is deformed by force, the inner clamp fixation may deform outward, and the outer clamp fixation may deform inward, resulting in poor clamping effect; and it is not convenient to limit the metal shell, and it cannot ensure that the metal shell is located in the middle of the fixture. For this reason, we propose a milling fixture for a vertical milling machine for the production of metal shells. Utility Model Content
