Description

Technical Field

[0001] The utility model relates to the technical field of casting grinding, in particular to a casting adjusting device for casting grinding. Background Technique

[0002] A casting is a metal formed object obtained by various casting methods, that is, the smelted liquid metal is injected into a pre-prepared mold by pouring, injection, suction or other casting methods. After cooling, through subsequent processing means such as grinding, an object with a certain shape, size and performance is obtained. For the castings formed by pouring, grinding devices are usually used to grind the surface to remove the burrs generated during melting and casting, making the surface of the casting smoother.

[0003] The existing Chinese utility model patent with the reference publication number: CN210616055U discloses a casting adjusting device for casting grinding, including a base. A side plate is fixed on the left side of the top of the base, and a grinding mechanism is fixed on the side plate. A fixing plate is movably installed on the outer wall of the top of the base, and a driving groove is opened on the top of the fixing plate. A screw rod is rotatably inserted into the driving groove. The screw rod passes through the outer wall of the fixing plate and is fixed with a first rotating handle. A driving block that forms a sliding fit with the driving groove is threadedly sleeved on the screw rod, and a placing plate is fixed on the top of the driving block, and a clamping mechanism is fixed on the top of the placing plate. The utility model drives the casting fixed between the placing plate and the clamping mechanism to approach the grinding mechanism, and thus can realize the adjustment work of the grinding depth, which is convenient and fast.

[0004] The existing casting adjusting devices generally can only adjust the relative position between the casting and the grinding disc. If the casting has an arc surface structure, it is impossible to rotate the casting during use to grind the arc surface. At the same time, the existing casting adjusting devices generally adjust the fixture gap through a screw rod to limit the position of the casting. This method requires tightening the screw rod to clamp the casting, and a large force is required to loosen the screw rod after the grinding is completed, which is very inconvenient.
