Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a machining fixture for a vertical machining center. Background Technology

[0002] Existing vertical machining centers typically use cast iron plates for tooling, with clamping blocks sliding on these plates. These blocks abut against the fixture, and the plates are then fastened to secure the fixture. During machining, cutting fluid tends to accumulate on the plate surface. Furthermore, due to the limitations of the clamping blocks, while they provide good clamping for standard fixtures, non-standard fixtures are necessary for irregularly shaped parts. The clamping blocks have limitations in this regard, requiring pins and bolts for positioning and installation. Since the plate is directly mounted on the vertical machining center platform, cutting fluid easily accumulates in the holes of the plate, affecting workpiece quality and machining accuracy. Moreover, the threaded holes on the plate wear down with repeated use, necessitating replacement of the entire plate and wasting material. Therefore, a new technical solution is urgently needed to address at least one of these problems. Summary of the Invention

[0003] The purpose of this invention is to provide a machining fixture for a vertical machining center. By cooperating with the lifting block and the fixture hole, the cutting fluid is drained, preventing it from accumulating on the table surface and thus avoiding excessive accumulation that could affect machining. The threaded sleeve can be replaced, reducing thread wear in the fixture hole and extending the service life of the table.

[0004] To achieve the above technical objectives and meet the above technical requirements, the technical solution adopted by this utility model is: a machining fixture for a vertical machining center, characterized in that it includes a base plate, a plurality of connectors detachably disposed on the upper side of the base plate, a plurality of lifting blocks disposed on the upper side of the base plate, and a platform disposed on the upper side of the base plate. The platform is provided with a plurality of fixture holes that penetrate vertically therethrough. The lifting blocks are detachably connected to the connectors, and hollow threaded sleeves are detachably disposed in the fixture holes.

[0005] As a preferred technical solution, the upper side of the substrate is provided with a plurality of T-shaped grooves, and the connector is a T-shaped block, which is slidably disposed in the T-shaped groove.

[0006] As a preferred technical solution, the tooling hole is a stepped hole, which includes an upper tooling hole and a lower tooling hole coaxially disposed below the upper tooling hole, and the upper tooling hole and the lower tooling hole are connected.

[0007] As a preferred technical solution, the upper hole of the tooling is detachably provided with a hollow bushing, and the threaded sleeve is detachably provided in the lower hole of the tooling.

[0008] As a preferred technical solution, the tooling holes are arranged in a linear and uniform array in the X and Y directions.

[0009] As a preferred technical solution, the upper side of the platform is provided with a row of X-direction marks for marking the tooling holes in the X direction.
