Description

Technical Field

[0001] This utility model relates to the technical field of casting grinding, and in particular to a metal casting grinding mechanism. Background Technology

[0002] A grinding machine, also called a grinding mechanism, consists of a housing, grinding components, and a working chamber. It utilizes the high-speed rotation of a grinding wheel within the grinding components to grind away burrs and flash from the surface or edges of metal castings, thus completing the precision finishing of the metal castings. It is widely used in the mold industry for precision machining and the removal of surface defects, flash, and burrs, greatly improving the efficiency of metal casting processing. Chinese utility model application number CN202322329079.X discloses a metal casting flash grinding mechanism that can handle workpieces of different sizes, thereby improving grinding efficiency. However, it is inconvenient to grind some longer metal castings, and the grinding tool uses a simple grinding structure, allowing only simple movement. It is not convenient for grinding some special castings, resulting in low grinding efficiency. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a metal casting grinding mechanism.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A metal casting grinding mechanism includes a base plate, on which a grinding device and a casting clamping structure are disposed. The grinding device includes two symmetrically arranged electric rotary seats, each with a flexible grinding disc coaxially driven at its upper end. The casting clamping structure includes an electric slide rail fixedly mounted on the base plate, on which a movable base is matched and mounted. A turntable is rotatably mounted on the side of the movable base near the grinding device, and a clamping component is fixedly disposed on the turntable. A stepper motor for controlling the rotation of the turntable is mounted on the movable base.

[0006] Preferably, the flexible grinding disc includes a flexible disc-shaped component as the main body and an annular abrasive belt disposed on the side wall of the flexible disc-shaped component.

[0007] Preferably, two limit switches corresponding to the movable bases are symmetrically fixed on the base plate.

[0008] Preferably, a dust suction port is fixedly provided on the base plate corresponding to two flexible grinding discs, and a dust suction device connected to the dust suction port is also fixedly provided on the base plate.

[0009] Preferably, both of the electric rotary seats are slidably mounted on the base plate, and two electric push rods for controlling the relative movement of the two electric rotary seats are also fixedly installed on the base plate.

[0010] Preferably, the clamping member adopts a structure similar to a bench vise.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: Addressing the problem that current grinding mechanisms can only handle workpieces of different sizes, but are inconvenient for grinding some long metal castings, this grinding mechanism adopts a transverse clamping structure that moves the metal casting between two grinding discs. This structure is more suitable for long metal castings, while also offering higher grinding efficiency and better grinding results. Furthermore, the grinding discs are flexible, making it easier to grind some special castings. It has high applicability, is easy to operate, ensures grinding efficiency, and is suitable for the production of long metal castings. It can grind long metal castings transversely and can also rotate the metal casting during grinding, achieving multi-directional grinding operations. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1-3 The metal casting grinding mechanism shown includes:

[0019] As the main supporting structure, the base plate 1 needs to be equipped with a grinding device and a casting clamping structure to realize the grinding operation of metal castings. Specifically, the grinding device includes two symmetrically arranged electric rotating seats 2. Both electric rotating seats 2 have a flexible grinding disc 3 coaxially driven at their upper ends. The electric rotating seats 2 are widely used in the prior art. The main structure is that a drive motor is installed on the base structure and the drive shaft is extended as the drive component, which can realize the drive rotation. The flexible grinding disc 3 is fixedly sleeved on the drive shaft. The fixing method can adopt the existing technology, such as bolt fixing, to achieve the detachable function and facilitate replacement when worn.

[0020] The grinding mechanism has been improved in terms of the structure of the grinding disc. The flexible grinding disc 3 includes a flexible disc-shaped part as the main body and an annular sand belt set on the side wall of the flexible disc-shaped part. During the grinding process, the edge of the grinding disc can change to a certain extent with the shape of the casting without affecting the rotation action, so as to achieve a better fit grinding effect.

[0021] When grinding castings, it is necessary to ensure the castings are clamped and fixed, and to control the movement of the castings to and from the grinding position. Therefore, the casting clamping structure includes an electric slide rail 4 fixedly installed on the base plate 1, a movable base 5 matchedly installed on the electric slide rail 4, a turntable 6 rotatably installed on the side of the movable base 5 near the grinding device, and a clamping component 7 fixedly installed on the turntable 6. The clamping component 7 is used to fix the metal castings and is suitable for long metal castings. At the same time, due to the rigidity of the metal castings themselves, the applicable length range is also limited. The clamping component 7 adopts a vise-like structure to ensure the stability of the clamping. A stepper motor 8 is installed on the movable base 5 to control the rotation of the turntable 6, which realizes the clamping and fixing of the metal castings, can also drive the metal castings to rotate to ensure the grinding range, and can also drive the metal castings to move. The overall grinding structure is more suitable for long metal castings.

[0022] In some embodiments, in order to ensure that the metal casting can be moved before installation, two limit switches 9 corresponding to the movable base 5 are symmetrically fixed on the base plate 1 to limit the movement range.

[0023] Meanwhile, during the grinding process, the waste generated during grinding needs to be processed. Therefore, a dust suction port 10 is fixedly installed on the base plate 1 corresponding to the two flexible grinding discs 3. A dust suction device 11 connected to the dust suction port 10 is also fixedly installed on the base plate 1. The dust suction device 11 adopts an existing device, such as a structure of a dust suction fan combined with a cylindrical filter.

[0024] In actual operation, the flexible grinding disc 3 may not be able to adapt to metal castings with large differences in width. Therefore, the two electric rotating bases 2 are slidably set on the base plate 1. The base plate 1 is also fixedly installed with two electric push rods 12 that control the relative movement of the two electric rotating bases 2, which can change the relative distance to ensure applicability.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
