Description

Technical Field

[0001] The utility model relates to the technical field of metal workpiece processing, and more specifically, to a milling tooling. Background Art

[0002] Milling is a common cold processing method for metal workpieces. During processing, the tooling needs to be fixed on the machine tool, and then the metal workpiece to be milled is clamped on the tooling through a fixture. The rotatable milling cutter equipped with the machine tool is used to feed on the end face or surface of the metal workpiece to cut out the required shape and features. That is, on the one hand, the milling cutter for milling needs to rotate under the drive of the main shaft, and on the other hand, it needs to move horizontally and / or vertically under the drive of the corresponding transmission mechanism (lead screw slider mechanism), while the metal workpiece to be processed is relatively stationary.

[0003] When processing arc-shaped parts, arc-shaped iron blocks are usually used to fix the arc-shaped parts so that they are in a standing state. However, this method has poor stability and is prone to the phenomenon of part displacement during processing, resulting in deviation of the processing accuracy of the parts and subsequent scrapping of the parts.

[0004] Therefore, as proposed in a patent with the publication number CN219254836U, a milling surface positioning tooling for a milling machine, through the cooperation of structures such as a clamping structure, a placement plate, and a device body, the arc-shaped parts on the placement plate are clamped through the clamping structure. When clamping, by controlling the rotation of the second rotating handle, the clamping plate is indirectly controlled to position and clamp the pipe fittings through the cooperation of the driving bevel gear and the driven bevel gear, and the operation is simple and the clamping effect is good. However, this application further fixes the arc-shaped parts through clamping, and the arc-shaped clamping surface has a limited range of arc-shaped parts that can be adapted for clamping. Those beyond the arc range will still be unstably clamped, and its clamping surface for irregular arc-shaped workpieces is also unstable. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a milling tooling to solve the technical problem that the existing milling surface positioning tooling has unstable clamping for irregular workpieces with arcs.

[0006] The embodiments of the utility model are realized through the following technical solutions:

[0007] A milling tooling includes a mounting plate for mounting a workpiece, a support seat provided on the mounting plate for placing and supporting the workpiece, and a clamping mechanism for clamping the workpiece. The support seat has an arc-shaped top surface and side surface, and the clamping mechanism includes a second clamping mechanism for lifting and clamping the workpiece and a first clamping mechanism for horizontally telescoping and clamping the workpiece.

[0008] Preferably, the mounting plate is provided with a plurality of groups of mounting holes for mounting and adjusting the support base, the second clamping mechanism and the first clamping mechanism.

[0009] Preferably, the first clamping mechanism includes a connecting column connecting the mounting hole and a ejector rod slidably connected to the connecting column, and the ejector rod is provided with a first fixing plate for fixing the workpiece.

[0010] Preferably, the second clamping mechanism includes a lifting column, a limiting column connecting the mounting hole and a top plate slidably connected to the lifting column, and the top plate is provided with an L-shaped second fixing plate for fixing the workpiece.

[0011] Preferably, the top plate is provided with a hole groove slidably connected to the limiting column, and a limiting sleeve for limiting it is provided at one end of the limiting column passing through the hole groove.

[0012] Preferably, the mounting plate is further provided with a limiting block for horizontally limiting the support base, and the limiting block is connected to the mounting hole.

[0013] Preferably, the support base is provided with a plurality of groups of fixing holes for fixing the workpiece.

[0014] Preferably, the mounting plate is further provided with a handle for gripping.

[0015] By adopting the technical solution, the support base with three-sided arc surfaces can be used to fit and prevent special-shaped workpieces with arc surfaces. Then, through the lifting second clamping mechanism and the telescopic first clamping mechanism, the outer sides of the workpiece are clamped and fixed in the horizontal direction and the resin direction respectively. Fixed from two directions, effectively preventing the special-shaped surface of the workpiece from being fixed by fitting through one surface, there are problems of incomplete fitting or unstable fixation due to too small fitting surface. If there are through holes on the workpiece, they can be aligned with the fixing holes of the support base, and the workpiece can be further fixed by bolts to improve the stability of the workpiece fixation;

[0016] A plurality of groups of mounting holes are provided on the mounting seat, and the support base, the first clamping mechanism and the second clamping mechanism can all adjust the position of the workpiece to be clamped and processed by adjusting the positions of the mounting holes where they are located, which is convenient for adjusting the position of the workpiece.
