Embodiment 1

[0033] In this embodiment, a rotation positioning structure, such as Figure 1 to Figure 6 As shown, it includes a working head 2, a handle 3 and a rotation adjustment assembly. Specifically, the above-mentioned working head 2 is hinged to the above-mentioned handle 3, the above-mentioned working head 2 is a hollow shell structure, and the above-mentioned rotation adjustment assembly is used to adjust and fix the above-mentioned working head. 2 rotation angle, during use, the above-mentioned working head 2 can rotate relative to the above-mentioned handle 3, and the rotation angle is regulated by the above-mentioned rotation adjustment assembly, so that the direction and positioning of the above-mentioned working head 2 can be adjusted as required.

[0034] By adopting this structure, the working head 2 of the rotary positioning structure of the present invention has no polishing dead angle, the operation is more convenient, and the working efficiency is improved.

Embodiment 2

[0036] This embodiment is further optimized on the basis of Embodiment 1. In this embodiment, as figure 1 and figure 2 As shown, one side of the above-mentioned working head 2 is provided with a hinge seat 6, and one end of the above-mentioned handle 3 is provided with a hollow connection seat 7. Swivel connection.

[0037] In this example, if figure 2 As shown, the above-mentioned working head 2 includes an upper casing 21 and a lower casing 22, the above-mentioned upper casing 21 and the lower casing 22 are connected by screws to form a hollow working head 2, and the above-mentioned upper casing 21 is provided with cooling holes. The bottom of the lower casing 22 is provided with a through hole for the output shaft of the motor 1 to pass through. The hinge seat 6 is arranged on the side wall of the lower casing 22 and integrally formed with the lower casing 22 .

[0038] As a specific implementation of this embodiment, such as figure 2 and Figure 4 As shown, the above...

Embodiment 3

[0046] In this embodiment, a grinding and polishing machine, such as Figure 7 As shown, it includes a motor 1, a polishing head 4, a power supply and a rotation positioning structure. The above-mentioned motor 1 is arranged in the above-mentioned working head 2, and the above-mentioned polishing head 4 is arranged at the bottom of the above-mentioned working head 2 and connected with the output shaft of the above-mentioned motor 1 , the power supply is arranged in the above-mentioned handle 3, and the above-mentioned working head 2 can rotate a certain angle relative to the above-mentioned handle 3 through the above-mentioned rotating top structure, and then drive the above-mentioned polishing head 4 to rotate together, and change the polishing direction of the above-mentioned polishing head 4. The structure enables the working head 2 of the grinding and polishing machine to be flexibly rotated and positioned, so that the above-mentioned polishing head 4 can be used for grindi...

Abstract

The invention relates to a rotation positioning structure, and belongs to the technical field of polishing tools, the rotation positioning structure comprises a working head, a handle and a rotation adjusting assembly, the working head is hinged to the handle, and the rotation adjusting assembly is used for adjusting the rotation angle of the fixed working head. The size of the rotating angle is adjusted through the rotating adjusting assembly, the direction of the working head is adjusted according to needs, the working head is positioned, by means of the structure, the working head of the rotating positioning structure is free of polishing dead angles, operation is more convenient, and the working efficiency is improved, and the invention further provides a grinding and polishing machine which comprises a motor, a polishing head, a power source and the rotating positioning structure. The motor is arranged in the working head, the polishing head is arranged at the bottom of the working head and connected with an output shaft of the motor, the power source is arranged in the handle, and the working head of the grinding and polishing machine can flexibly rotate and be positioned, so that the polishing head can grind and polish various narrow special-shaped positions, no machining dead angle exists, and the applicability is wider.

Description

technical field [0001] The invention belongs to the technical field of polishing and polishing tools, and in particular relates to a rotation positioning structure and a polishing and polishing machine. Background technique [0002] At present, in the auto beauty, auto maintenance, and auto repair markets of the automotive industry, manual brushes or small right-angle grinders are used for grinding, polishing, and cleaning of small areas at the dead corners of paint surfaces, door seams, and grids. Manual brushes work efficiently. Slow, the technology of the small right-angle grinder is outdated, the working head cannot be rotated, and the applicability is poor. It is only suitable for grinding, polishing, and cleaning on a flat surface. The position of the concave structure requires the operator to adjust his own position and the angle of the hand-held grinder to fit the narrow and special-shaped position, so that he can barely perform grinding and polishing, which is time-...
