Description

Technical Field

[0001] This utility model relates to the field of polishing machine technology, specifically a polishing machine with hand protection function. Background Technology

[0002] Polishing machines, also known as grinding machines, are commonly used for mechanical grinding, polishing, and waxing. They are typically used to polish and grind ceramic balls by rubbing the surface of the ceramic balls with a polishing disc, thereby removing paint contamination, oxide layers, and shallow scratches from the ceramic balls and improving their smoothness.

[0003] However, the use of large polishing equipment is limited in some situations where manual polishing with sand or grinding wheels is required, which is slow.

[0004] To address the aforementioned shortcomings, Chinese Patent Publication No. CN219053946U discloses a handheld grinding and polishing machine, comprising a grinding and polishing section, a support section, and a motor. The grinding and polishing section has a motor at its lower end, rotatably connected to the grinding and polishing section. The motor has a support section at its lower end, fixedly connected to the support section, and is located inside the support section. The grinding and polishing section has a protective shell and a limiting spring block, enabling both handheld grinding and polishing functions. The left and right gears mesh with the motor gears to rotate the left and right wheels. When the right wheel rotates, the abrasive belt polishes; when the left wheel rotates, since it is a grinding wheel, it grinds the workpiece. Only one wheel needs to be rotated at a time.

[0005] The aforementioned device uses gears and motor gears to drive the sanding belt for polishing during use. However, the meshing of gears and motor gears in the aforementioned device only drives the sanding belt for polishing. The sparks that fly during polishing can easily injure the operator's hands, thus affecting the polishing efficiency. Utility Model Content

[0006] The purpose of this invention is to provide a polishing machine with hand protection function to solve the problem mentioned in the background art that the sparks flying during polishing can easily injure people's hands.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a polishing machine with hand protection function, comprising a housing, a handle fixedly installed on the outer surface of the housing, a protective shell fixedly installed on the outer surface of the housing, an anti-slip texture installed on the outer surface of the handle, an arc-shaped baffle movably abutting against the outer surface of the housing, and a protective mechanism provided between the protective shell and the arc-shaped baffle; a grip fixedly installed on the outer surface of the housing, a switch fixedly installed on the outer surface of the handle, and a polishing mechanism provided between the switch and the grip.

[0008] Furthermore, a rubber sleeve is fixedly installed on the outer surface of the grip, a fixed sleeve is movably installed on the outer surface of the grip, and a connecting block is fixedly installed on the outer surface of the fixed sleeve.

[0009] Furthermore, a helical rod is threaded onto the inner side of the grip, and a fixed disc is fixedly mounted on the outer surface of the helical rod, with the helical rod and the fixed disc forming an integral structure.

[0010] Furthermore, the protection mechanism includes an arc-shaped baffle, which is fixedly installed on the bottom surface of the connecting block. The bottom surface of the arc-shaped baffle is movably abutted against a base, and the connecting block and the arc-shaped baffle form an integral structure.

[0011] Furthermore, a stepper motor is fixedly installed on the inner side of the housing, an output shaft is rotatably installed at the output end of the stepper motor, a rotating rod is fixedly installed on the outer surface of the output shaft, and the output shaft and the rotating rod form a rotating structure.

[0012] Furthermore, the polishing mechanism includes an adjusting shaft, which is fixedly mounted on the outer surface of the rotating rod. A polishing disc is fixedly mounted on the bottom surface of the adjusting shaft, and the adjusting shaft and the polishing disc form a rotating structure.

[0013] Furthermore, a base is fixedly installed on the outer surface of the housing, a rubber sleeve is fixedly installed on the outer surface of the housing, and a fixed sleeve is movably abutted against the outer surface of the rubber sleeve.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) Manually put the fixing sleeve into the handle. The fixing sleeve drives the connecting block to move, and the connecting block drives the arc baffle to move, so that the arc baffle is placed on the surface of the outer shell and supported by the base. The rubber sleeve limits the fixing sleeve and reduces the vibration generated by the hand, thus improving the comfort of the personnel.

[0016] (2) By manually rotating the fixed plate, the fixed plate drives the screw rod to rotate, which facilitates the installation and removal of the fixed sleeve, and makes it easier to protect the hands of personnel during processing, thereby improving personnel safety.

[0017] (3) By starting the stepper motor, the stepper motor drives the output shaft to rotate, the output shaft drives the rotating rod to rotate, the rotating rod drives the adjusting shaft to rotate, and the adjusting shaft drives the polishing disc to rotate, thereby facilitating the polishing of items and improving the processing efficiency of the equipment;

[0018] (4) The polishing disc is protected by a protective shell, and the anti-slip texture on the handle prevents it from coming off during polishing, thus facilitating stable operation of the equipment. Attached Figure Description
