Description

Technical Field

[0001] This utility model relates to the field of boring fixture technology, specifically a front cover boring fixture. Background Technology

[0002] The front cover has holes formed during casting, but these holes are relatively rough. To facilitate subsequent work, a boring machine is used to further process these holes. When boring, the boring tool on the front cover can enlarge the hole diameter, improve accuracy, reduce surface roughness, and effectively correct any misalignment of the original hole axis. However, existing boring machines can only clamp front covers of specific sizes, significantly increasing the cost of fixture production for companies. The poor adaptability of the fixtures hinders cost reduction. Utility Model Content

[0003] The purpose of this utility model is to provide a front cover boring fixture to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a front cover boring fixture, comprising a connecting seat, a fixed cylinder fixedly connected to the connecting seat, a positioning post slidably connected inside the fixed cylinder, a front cover body above the connecting seat, a positioning cavity in the middle of the front cover body, a positioning hole in the middle of the front cover body, the positioning post and the positioning hole being coaxial, multiple support plates fixedly connected to the upper end of the connecting seat, an adjusting plate slidably connected to the middle of the support plates, multiple limiting rubber sheets fixedly connected to the side end of the adjusting plate, an installation ring rotatably connected to the middle of the positioning post, a drive rod hinged to the side end of the installation ring, an adjusting cavity inside the connecting seat, a fixed gear inside the adjusting cavity, a drive gear meshing with the side end of the fixed gear, a drive motor inside the adjusting cavity, the drive gear and the power output end of the drive motor being fixedly connected, and limiting beads embedded in the inner wall of the adjusting cavity.

[0005] Preferably, the support plate is arranged around the fixed cylinder, the adjusting plate has a T-shaped structure, and the top of the adjusting plate is hinged to the drive rod.

[0006] Preferably, the mounting ring is located inside the fixed cylinder, and the side end of the fixed cylinder is provided with multiple sliding grooves, each of which corresponds to a support plate, and both ends of the drive rod pass through the sliding grooves.

[0007] Preferably, the upper end of the limiting rubber sheet is a vertical structure, the upper sidewall of the limiting rubber sheet is provided with a suction cup, and the lower end of the limiting rubber sheet is an arc-shaped structure.

[0008] Preferably, the lower end of the positioning post is located inside the adjustment cavity, the lower end of the positioning post is provided with an external thread, and the lower end of the positioning post is threadedly connected to the fixed gear.

[0009] Preferably, the upper end of the fixed gear is provided with a limiting groove, the bottom of the limiting groove is an arc-shaped structure, and the limiting groove is an annular structure.

[0010] Preferably, the left side of the fixed gear is slidably connected to the inner wall of the adjusting cavity, and the lower end of the limiting bead is slidably connected to the limiting groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: First, the positioning pin and positioning hole are interlocked to position the front cover body. At this time, the drive motor drives the drive gear to rotate, thereby moving the positioning pin downward. At the same time, the adjusting plate moves away from the fixed cylinder, lowering the limiting rubber against the positioning cavity of the front cover body, thereby positioning and fixing the front cover body. The adjusting plate can move different distances to position and fix front cover bodies of different sizes, making it more adaptable and greatly reducing the cost of enterprises. Moreover, when boring the positioning hole, the positioning pin retracts into the fixed cylinder, which will not interfere with the boring. Attached Figure Description
