Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of broaching machine equipment, and particularly relates to an automatic tool changing mechanism of a broaching machine. BACKGROUND

[0002] A broaching machine is a common machining machine tool, which uses a broach as a tool to machine a workpiece through hole, a plane and a shaped surface. The broaching machining by the broach can make the parts obtain high dimensional accuracy and produce small surface roughness, and the machining process has high productivity and is suitable for batch mass production. As the main machining tool of the machine tool, the broach will be worn after long time work, and thus needs to be frequently replaced. Most of the existing broaching machines need to replace the broach manually, and the replacement process is relatively troublesome, and the worn broach is easy to cause the operator to be injured. A small part of the broaching machines are provided with relatively simple replacement devices, but the replacement devices have low efficiency and cannot completely replace the manual operation.

[0004] The utility model discloses a technical scheme that solves the technical problems:

[0005] An automatic tool changing mechanism of a broaching machine, comprising a mounting angle iron fixed on the broaching machine and located on the same straight line with a broach transmission device, a base fixed on the mounting angle iron, characterized in that: a sliding groove is formed in the base, a sliding block transmission device moving along the sliding groove is arranged in the sliding groove, a sliding block assembly located above the base is fixed on the sliding block transmission device, a mechanical hand is arranged at one end of the sliding block assembly close to the broach transmission device; mounting blocks corresponding to the sliding block assembly are arranged at both ends of the base, oil pressure buffers are fixed in the mounting blocks; a light rod is arranged at both sides of the base, a plurality of wheel sets matching the light rod and located outside the light rod are arranged at the bottom of the sliding block assembly.

[0006] Further, a metal cover block covering the mechanical hand is fixed on the sliding block assembly. The metal cover block can protect the structure of the mechanical hand and the sliding block assembly, so as to improve the service life of the mechanism.

[0007] Further, the mechanical hand comprises a driving body fixed on the sliding block assembly and a plurality of broach clamping fingers arranged on one side of the driving body.

[0008] Further, the sliding block transmission device comprises a movable rod fixed in the sliding groove, a linkage block movably connected to the movable rod and a linkage drive arranged on one side of the linkage block, and the linkage block is fixedly connected to the bottom of the sliding block assembly.

[0009] Compared with the prior art, the utility model has the advantages and effects that: the automatic replacement of the broach is realized through the setting of the mechanical hand structure (wheel group matches with the polished rod), the accuracy is high, the replacement speed is more efficient, and the operator can be prevented from being accidentally injured.
