Abstract
Description
Technical Field
[0001] This utility model belongs to the field of angle grinders, specifically an angle grinder that can simultaneously cut and grind. Background Technology
[0002] Handheld angle grinders and cutting machines are common processing tools. Existing angle grinders and cutting machines are two separate products due to their different functions and housings. This design results in higher operating costs. Moreover, the housings of existing cutting machines and angle grinders are fixed and cannot be adjusted according to usage needs. In some situations, sparks cannot be properly channeled, making use unsafe. Therefore, there is an urgent need in this field for a multi-functional cutting and angle grinder that integrates cutting and grinding, while also allowing for free adjustment of the housing according to usage requirements. Utility Model Content
[0003] In view of the shortcomings of existing handheld angle grinders and cutters, the technical problem to be solved by this utility model is to provide a multi-functional cutting angle grinder with both grinding and cutting functions, and the protective cover of the multi-functional cutting angle grinder can be selected and its angle adjusted according to the usage requirements.
[0004] To achieve the above objectives, according to one aspect of the present invention, the present invention is implemented through the following technical measures: a multi-functional cutting angle grinder, comprising:
[0005] The angle grinder body is equipped with a dust cover, and an output shaft driven to rotate by the angle grinder body is located at the center of the dust cover.
[0006] The output shaft is equipped with a machining component, which consists of a lower pressure plate, a grinding wheel or cutting disc, and an upper pressure plate in sequence.
[0007] The grinding wheel can be replaced by removing the upper pressure plate;
[0008] The angle grinder body is also equipped with a rotating platform, and the dust cover is fitted onto the rotating platform and can rotate.
[0009] The multi-functional cutting angle grinder also includes a rotating pressure plate, which is fixed to the angle grinder body by bolts, and the rotating pressure plate is provided with a baffle plate to limit the dust cover and prevent the dust cover from separating from the rotating table;
[0010] The multi-functional cutting angle grinder also includes an outer cover, which is fitted over the outside of the dust cover. When the outer cover is fitted over the outside of the dust cover, the cutting blade is a workpiece component.
[0011] This multi-functional cutting angle grinder features a rotating table and a dust cover that can be mounted on the rotating table. This allows the dust cover to be adjusted according to usage needs. At the same time, a rotating pressure plate limits the dust cover to prevent it from separating from the rotating table, and the detachable outer cover design improves cutting safety.
[0012] Furthermore, the dust cover is also provided with an arc-shaped guide groove, and the rotating pressure plate is provided with a locking head that engages within the arc-shaped guide groove. This design controls the distance of the rotation angle.
[0013] Furthermore, the dust cover on the outer side of the arc-shaped guide groove is also equipped with a circular track with several locking points. The lower end of the baffle plate is equipped with a spring-loaded column that is elastic or capable of rebounding. By rotating the dust cover, one of the locking points can be engaged with the spring-loaded column. The above design is for quick rotation angle positioning and is also safer to use.
[0014] Furthermore, the baffles consist of multiple pieces arranged in a circular array on the rotating pressure plate. Each baffle has a spring post at its lower end, and only one of these spring posts engages with the locking point. This design aims to improve stability during use.
[0015] Furthermore, the aforementioned locking points are arranged opposite to the arc-shaped guide groove. This design structure is more rational.
[0016] Furthermore, the lower end of the rotating pressure plate is also provided with an elastic washer.
[0017] Furthermore, the outer cover is also provided with two opposing locks, which are used to lock and fix the cover.
[0018] Compared with the prior art, the advantages of this utility model are as follows: the double-cover design enables the handheld angle grinder to be used as a cutting machine, and the rotatable cover design allows for adjustment according to usage needs, increasing safety. The design of several locking points and elastic columns enables quick rotation and positioning, making it more convenient to use. Attached Figure Description
