Description

A car clamp clamped inside the starter end cover

technical field

The utility model relates to a machining fixture, in particular to a clamp for clamping a vehicle inside the end cover of a starter.

Background technique

In the machining industry, turning is a commonly used machining method. Fixtures are used when the workpiece needs to be fixed during machining operations. The traditional clamping scheme is to use a three-jaw fixture for clamping, and use the jaws to fix the surface of the workpiece to be processed.

In the starter manufacturing process, after the casting of the end cover is completed, the end face hole of the end cover needs to be turned and processed. Figure 1 and Figure 2 are three-dimensional schematic diagrams of the end cover 10 to be processed in two perspectives. The upper end of the end cover is provided with a center The hole 101 is provided with a side working hole 102 on the side, and an end face hole is provided on its end face 103 . According to the traditional clamping method above, since the clamp jaws have no directional reference, the operator must visually avoid the clamp to interfere with the clamped workpiece, and the clamping efficiency is low; and the directions of the clamped workpieces are different, which is easy to cause Improper clamping will lead to uneven installation and warping of the workpiece, resulting in unstable processing and unqualified product size.

At the same time, the traditional three-jaw clamping method is mainly suitable for positioning and processing cylindrical parts. For the processing of special-shaped parts similar to end caps, positioning shaking is easy to occur; and the claws on the fixture directly contact the outer surface of the workpiece, which is likely to cause surface damage. Damage, improper operation can easily lead to defective products.

In addition, different actual needs lead to different product sizes, and the end caps correspond to different models and are not uniform, which brings certain troubles to processing and manufacturing. The existing end cap clamping standards are different for different types of end caps. Unified, in order to adapt to different types of end caps, different fixtures are required; and when different types of end caps are produced at the same time, because the fixtures are not universal, multiple equipment or different types of fixtures are required to be replaced during production.

Further, a hook head (602) is provided at the front end of the hook-shaped pressing plate (6).

Further, the hollow side of the body (1) is movably provided with a support seat (7), on which the waist-shaped hole (601) of the hook-shaped pressing plate (6) is movably connected through the hinge shaft (2).

Further, the hinge shaft (2) is fixed by a cotter pin (3).

Further, a detent pin (8) is arranged on the positioning plate (5).

Beneficial effects of the utility model: 1. The utility model clamps the clamp inside the end cover of the starter, realizes the uniform processing of the end covers of different sizes and models, and does not need to replace the processing fixture.

2. Realize the precise fixing of the starter end cover, which is fixed firmly and without shaking.

3. It is convenient and efficient to pick and place the workpiece, and the product processing is less affected by the workers' clamping technology.

4. The fixture does not contact the outer surface of the workpiece to be processed, does not damage the outer surface of the workpiece, and will not cause defective products due to damage to the outer surface of the workpiece.
