Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing equipment, specifically to an integrated rotatable grinding fixture. Background Technology

[0002] Currently, aluminum alloy steering knuckles with complex hollow structures require surface cleaning and polishing after casting. Existing polishing methods often involve manual movement of the product. This manual movement not only causes wear and tear on the parts but also easily damages the inner surface when removing irregularly shaped structures, leading to product scrap. It's impossible to simultaneously achieve optimal appearance quality. High-end vehicle steering knuckles have even higher requirements for appearance quality, requiring extra care during cleaning to ensure that burrs and sharp edges are completely removed while preventing any damage to the surface. Therefore, designing a polishing fixture is essential. Utility Model Content

[0003] The purpose of this invention is to address the above-mentioned shortcomings by providing an integrated, rotatable grinding fixture.

[0004] This utility model includes a base and a worktable. The base is equipped with a pair of rotation adjustment mechanisms on the top, and the worktable is installed between the pair of rotation adjustment mechanisms. The worktable has a workpiece clearance groove and a workpiece clearance hole. The worktable is equipped with a workpiece support block and a pressure plate support block in the middle. The pressure plate support block is equipped with a workpiece pressure plate on top, and the workpiece pressure plate is located above the workpiece support block.

[0005] The rotation adjustment mechanism includes a sleeve, a rotating shaft, and a handwheel. The sleeve is mounted on the top of the base, and the rotating shaft is movably mounted inside the sleeve via a set of bearings. A handle seat is provided in the middle of the handwheel, and the handle seat is mounted on one end of the rotating shaft. A connecting plate is provided on the other end of the rotating shaft, and the worktable is mounted between the connecting plates of a pair of rotation adjustment mechanisms.

[0006] A cover plate is provided at the end of the shaft, and the cover plate is installed on the shaft by screws. The handwheel seat is located between the cover plate and the sleeve.

[0007] The connecting plate is detachably mounted on the end of the shaft by a set of bolts.

[0008] A set of positioning grooves are evenly distributed in a ring on the outer circumference of the connecting plate. An L-shaped pin block is provided on the top of the sleeve. The top of the L-shaped pin block has a pin hole. The positioning pin passes through the pin hole and is inserted into the corresponding positioning groove.

[0009] A mounting block is provided on the end face of the connecting plate, and the end of the worktable is detachably mounted on the mounting block by bolts.

[0010] A pressure plate fixing seat is provided on the worktable below the workpiece pressure plate. An adjustment hole is opened on the workpiece pressure plate, and bolts are installed on the pressure plate fixing seat through the adjustment hole. A transverse pressure plate is provided at the bottom of the pressing end of the workpiece pressure plate.

[0011] The top of the workpiece support block is provided with a frustum-shaped workpiece contour positioning part.

[0012] When the workpiece is mounted on the workbench, a profile hammer A is installed above the workpiece clearance groove, and a profile hammer B is installed inside the workpiece clearance hole.

[0013] The base has an H-shaped base plate at the bottom, with a pair of support columns on the H-shaped base plate. A reinforcing rod is installed between the support columns and the H-shaped base plate, and the rotation adjustment mechanism is installed on the top of the support columns.

[0014] The advantages of this invention are: it ensures the product remains stationary while the tooling rotates to perform cleaning and polishing, while a contour hammer removes irregular structures. This ensures the product meets both cleaning and polishing quality standards and maintains its appearance quality, thus satisfying customer requirements. Attached Figure Description
