Description

Technical Field

[0001] This utility model belongs to the field of steel surface treatment technology, and specifically relates to a steel surface treatment processing device. Background Technology

[0002] Steel surface treatment mainly includes three categories: mechanical treatment, chemical treatment, and coating treatment. Mechanical treatment commonly uses sandblasting, shot blasting, grinding (using grinding wheels or sandpaper to eliminate roughness), and polishing (to obtain a mirror effect); chemical treatment includes pickling, phosphating, and electroplating; coating treatment uses spraying and dip plating.

[0003] For common steel surface roughness treatments, such as the removal of burrs and rust from steel plates and pipes, a handheld electric surface grinder is usually used. Surface grinders are not only portable and easy to operate, but also have relatively low-cost grinding discs. They are suitable not only for routine deburring and rust removal, but also for routine polishing of steel surfaces by changing the grinding wheel to different grit sizes and using grinding fluid or granules.

[0004] However, the circular grinding discs of current handheld flat electric grinders are generally flat. When grinding steel, the circular grinding disc is usually in close contact with the surface of the steel. During grinding, some grinding particles may adhere to the rough surface. If these particles are not cleaned off in time, the grinding effect will be reduced, and sometimes scratches may even appear on the surface of the steel. On the other hand, it will also accelerate the wear rate of the circular grinding disc. Utility Model Content

[0005] To address the above problems, the purpose of this utility model is to provide a steel surface treatment processing device, which solves the problem that the circular grinding discs of current handheld flat electric grinders are generally flat. When grinding steel, the circular grinding discs are usually in close contact with the steel surface. During grinding, some grinding particles sometimes adhere to the rough surface. If these particles are not cleaned off in time, it will reduce the grinding effect and sometimes even cause scratches on the steel surface. On the other hand, it will also accelerate the wear rate of the circular grinding discs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a steel surface treatment processing device, comprising a main body shell, a control shell fixedly disposed on one side of the main body shell, a handle fixedly disposed on the side of the control shell away from the main body shell, a motor disposed inside the main body shell, the output end of the motor penetrating through the main body shell to a fixed plate fixedly disposed on the lower side, a control board and a battery module fixedly disposed inside the control shell, a grinding disc disposed on the lower side of the fixed plate, and a screw threaded in the center of the lower side of the grinding disc. The grinding disc and the fixed disc are threaded together. The bottom center of both the fixed disc and the grinding disc is a circular plane. The outer sides of both the fixed disc and the grinding disc are annular inclined surfaces that slope outward and upward. A fixing rod is fixedly installed on the lower side of the control housing near the main housing. A collar is provided at the lower end of the fixing rod. A brush rod is fixedly installed on the side of the collar near the grinding disc. The brush rod is parallel to the lower side of the annular inclined surface of the grinding disc. Brush bristles are evenly arranged on the upper side of the brush rod and are close to the annular inclined surface of the grinding disc.

[0007] The beneficial effects of this utility model are as follows: Since the outer side of the lower side of the grinding disc is an upwardly inclined annular slope, which is the grinding surface, during grinding, it is only necessary to make the side of the annular slope away from the control shell fit against the grinding surface. The side of the grinding disc near the handle will tilt upward. When the grinding disc rotates, the brush rod will fit against the lower side of the grinding disc, and the brush bristles will continuously brush the annular slope of the grinding disc, which can quickly clean the particles attached to the annular slope of the grinding disc, avoid the particles affecting the grinding effect, and avoid the presence of particles accelerating the wear of the grinding disc.

[0008] In order to fine-tune the fit of the bristles on the brush handle to the grinding disc;

[0009] As a further improvement to the above technical solution: the collar is slidably sleeved with the fixing rod, the lower end of the fixing rod is threaded with a nut, the nut is pressed against the lower side of the collar, the upper side of the collar is sleeved with a spring on the outer side of the fixing rod, the upper side of the spring is pressed with a fixing plate, and the fixing plate is fixedly connected to the fixing rod.

[0010] The beneficial effects of this improvement are as follows: when the nut is turned, the collar on the nut is pressed down, the collar pushes the spring to compress, and at the same time the collar drives the brush rod to move, which is used to fine adjust the tightness of the brush bristles on the brush rod to the grinding disc.

[0011] To be used to blow away particles generated during polishing;

[0012] As a further improvement to the above technical solution: a fan is fixedly installed on the lower side of the control shell away from the main shell, and the output end of the fan is connected to a blower shell, with the output port of the blower shell facing the lower side of the grinding disc.

[0013] The beneficial effects of this improvement are: by installing a fan, air can be continuously blown onto the underside of the grinding disc through the air blower housing to blow away the particles generated during grinding.

[0014] In order to increase the heat dissipation effect of the polished surface to a certain extent;

[0015] As a further improvement to the above technical solution: fine grooves are equidistantly arranged around the annular inclined surface of the grinding disc.

[0016] The beneficial effects of this improvement are as follows: the fine grooves are designed to increase the heat dissipation of the grinding surface to a certain extent. The fine grooves can evenly disperse the thermal and mechanical stress of the grinding disc, reduce the risk of local deformation, and extend its service life.

[0017] To increase the connection stability between the grinding disc and the fixed disc;

[0018] As a further improvement to the above technical solution: the upper side of the grinding disc is equidistantly surrounded by locking blocks, which are inserted and locked into the fixed disc.

[0019] The beneficial effect of this improvement is that it increases the connection stability between the grinding disc and the fixed disc.

[0020] To increase stability during polishing;

[0021] As a further improvement to the above technical solution: an auxiliary rod is fixedly provided on one side of the main shell.

[0022] The beneficial effects of this improvement are: it helps to assist in holding the object and increases stability during polishing.

[0023] To increase hand comfort during sanding;

[0024] As a further improvement to the above technical solution: rubber sleeves are fitted on the outer sides of both the handle and the auxiliary rod, and the two rubber sleeves are respectively set to correspond to the size of the handle and the auxiliary rod. Rubber rings are fixedly provided at equal intervals on the inner side of the rubber sleeves, and the rubber rings are tightly fitted on the outer sides of the handle and the auxiliary rod.

[0025] The beneficial effects of this improvement are: the rubber sleeve, through the rubber ring and the internal gap, reduces the transmission of vibration to the hand, thereby increasing hand comfort during sanding.

[0026] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0033] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0034] like Figure 1 — Figure 5As shown: A steel surface treatment processing device includes a main body shell 1. A control shell 2 is fixedly installed on one side of the main body shell 1. A handle 3 is fixedly installed on the side of the control shell 2 away from the main body shell 1. A motor is installed inside the main body shell 1. The output end of the motor passes through the main body shell 1 and is fixedly installed on the lower side of a fixing plate 5. A control board and a battery module are fixedly installed inside the control shell 2. A grinding disc 6 is installed on the lower side of the fixing plate 5. A screw 7 is threaded in the middle of the lower side of the grinding disc 6. The screw 7 passes through the grinding disc 6 and is threadedly connected to the fixed disc 5. The bottom center of the fixed disc 5 and the grinding disc 6 is a circular plane. The outer sides of the circular plane of the fixed disc 5 and the grinding disc 6 are both annular inclined surfaces that slope outwards and upwards. A fixing rod 8 is fixedly installed on the lower side of the control housing 2 near the main housing 1. A collar 9 is provided at the lower end of the fixing rod 8. A brush rod 10 is fixedly installed on the side of the collar 9 near the grinding disc 6. The brush rod 10 is arranged parallel to the lower side of the annular inclined surface of the grinding disc 6. The upper side of the rod 10 is evenly covered with bristles, which are set close to the annular inclined surface of the grinding disc 6. Since the outer side of the lower side of the grinding disc 6 is an upwardly inclined annular surface, which serves as the grinding surface, during grinding, it is only necessary to align the side of the annular inclined surface away from the control housing 2 with the grinding surface. The side of the grinding disc 6 closest to the handle rod 3 will tilt upwards. When the grinding disc 6 rotates, the brush rod 10 will be close to the lower side of the grinding disc 6, and the bristles will continuously brush the annular inclined surface of the grinding disc 6, which can quickly clean away the grinding residue. The particles attached to the annular inclined surface of the grinding disc 6 are prevented from affecting the grinding effect and from accelerating wear of the grinding disc 6. The collar 9 is slidably sleeved with the fixing rod 8. The lower end of the fixing rod 8 is threaded with a nut 11, which is pressed against the lower side of the collar 9. A spring 13 is sleeved on the upper side of the collar 9 outside the fixing rod 8. A fixing plate 12 is pressed against the upper side of the spring 13. The fixing plate 12 is fixedly connected to the fixing rod 8. Tightening the nut 11 presses the collar 9 down.The collar 9 pushes the spring 13 to compress, and at the same time, the collar 9 drives the brush rod 10 to move, which is used to fine adjust the adhesion of the bristles on the brush rod 10 to the grinding disc 6. A fan 14 is fixedly installed on the lower side of the control shell 2 away from the main shell 1. The output end of the fan 14 is connected to a blower shell 15. The output port of the blower shell 15 is set towards the lower side of the grinding disc 6. The fan 14 can continuously blow air onto the lower side of the grinding disc 6 through the blower shell 15 to blow away the particles generated during grinding. Fine grooves 61 are evenly spaced around the annular inclined surface of the grinding disc 6. The fine grooves 61 are used to increase the heat dissipation effect of the grinding surface to a certain extent. The design of the fine grooves 61 can evenly distribute the thermal stress and mechanical stress of the grinding disc and reduce the risk of local deformation. To extend service life, the upper side of the grinding disc 6 is equidistantly surrounded by locking blocks 62, which are inserted into and engaged with the fixed disc 5 to increase the connection stability between the grinding disc 6 and the fixed disc 5. An auxiliary rod 16 is fixedly installed on one side of the main body shell 1 to assist gripping and increase stability during grinding. Rubber sleeves are fitted onto the outer sides of both the handle 3 and the auxiliary rod 16, with the two rubber sleeves corresponding to the dimensions of the handle 3 and the auxiliary rod 16 respectively. Rubber rings are equidistantly fixed onto the inner sides of the rubber sleeves, tightly fitted onto the outer sides of the handle 3 and the auxiliary rod 16. The rubber sleeves, through the rubber rings and internal gaps, reduce vibration transmission to the hand, increasing hand comfort during grinding.

[0035] Working principle and usage process of this utility model:

[0036] In use, hold the handle 3 and control the motor to start via the control button 4. The motor's output drives the fixed plate 5 to rotate, which in turn drives the grinding disc 6 to rotate. Since the lower outer side of the grinding disc 6 is an upward-sloping annular bevel, which serves as the grinding surface, during grinding, simply ensure that the side of the annular bevel furthest from the control housing 2 is in contact with the grinding surface. The side of the grinding disc 6 closest to the handle 3 will tilt upwards. As the grinding disc 6 rotates, the brush rod 10 will press against the lower side of the grinding disc 6, and the bristles will continuously brush the annular bevel of the grinding disc 6, quickly removing particles adhering to the annular bevel and preventing particles from affecting the grinding effect and accelerating wear on the grinding disc 6. Additionally, tightening the nut 11 presses the collar 9 onto the nut 11, and the collar 9 pushes the spring... Spring 13 is compressed, and collar 9 drives brush rod 10 to move, which is used to fine adjust the tightness of the brush bristles on brush rod 10 to the grinding disc 6. In addition, a fan 14 is provided, which can continuously blow air to the lower side of the grinding disc 6 through the blower shell 15 to blow away the particles generated during grinding. In addition, a groove 61 is provided to increase the heat dissipation effect of the grinding surface to a certain extent. In addition, a locking block 62 is fixedly provided at equal intervals around the upper side of the grinding disc 6. The locking block 62 is inserted and locked with the fixed plate 5 to increase the connection stability between the grinding disc 6 and the fixed plate 5. In addition, an auxiliary rod 16 is fixedly provided on one side of the main body shell 1 to assist in holding and increase the stability during grinding. In addition, a rubber sleeve is provided, which reduces the transmission of vibration to the hand through the rubber ring and internal gap, increasing the hand comfort during grinding.
