Description

Technical Field

[0001] The utility model relates to the technical field of machining, in particular to a top workbench on the feeding side of a machining center. Background Technique

[0002] At present, the clamping of workpieces in machining restricts the degrees of freedom in the horizontal direction or the vertical direction separately through fixtures. If it is necessary to restrict the degrees of freedom in both directions simultaneously, two sets of fixtures must be used for clamping. Moreover, when restricting the degrees of freedom in the vertical direction, usually the fixture occupies a part of the upper surface of the workpiece during the machining state, and the relationship between the machining surface and the clamping part of the fixture often needs to be considered, resulting in long working hours and inconvenient installation.

[0003] At present, although there are side-top fixtures, they can only restrict the degrees of freedom of the workpiece in the horizontal direction and cannot restrict the degrees of freedom in the vertical direction simultaneously.

[0004] For example, a side-top machining fixture disclosed in the patent with the publication number CN218284665U clamps the workpiece laterally to maintain the machining area of the upper end surface. However, the fixture needs to cooperate with a back plate, a vertical plate or a wall surface, so that the side of the workpiece has a second contact surface to realize the clamping operation. Therefore, auxiliary components are required for use. Secondly, when the front and rear end surfaces and the lower end surface of the workpiece need to be machined, the workpiece needs to be removed and the direction needs to be adjusted to re-clamp it. Otherwise, when using this fixture, it is inconvenient for the user to perform machining operations on other surfaces except the upper end surface.

[0005] However, when clamping the side of the workpiece, this device has low clamping efficiency and cannot position the workpiece, affecting the machining accuracy of the workpiece.

[0006] Therefore, we urgently need to provide a top workbench on the feeding side of a machining center. Content of the Utility Model
