Description

Technical Field

[0001] The utility model relates to the field of end grinders for stainless steel pipes, and particularly to an end grinder for stainless steel pipes. Background Art

[0002] During the processing of stainless steel pipes, an end grinder is required to polish the end faces of the cut stainless steel pipes, so as to improve the smoothness of their end faces.

[0003] For example, an end grinder for stainless steel pipes disclosed in the utility model with the authorization announcement number CN213351837U is equipped with a protective sleeve. When the user holds the handle to control the main body of the device to polish the steel pipe, due to the rotation of the motor driving the polishing plate to polish the steel pipe, a large vibration will be generated. When the user holds the handle, the vibration generated by the protective sleeve will be buffered by squeezing the second spring, so that the user's hand is not easily paralyzed due to long-term vibration when using this device for a long time. And the sound-absorbing cotton can absorb the noise generated when the polishing plate polishes the steel pipe, improving the environmental protection. However, since a large amount of dust and other debris will be generated during the polishing of stainless steel pipes, and most of the current end grinders for stainless steel pipes do not have a dust adsorption and purification structure, the dust generated during polishing will spread in the surrounding environment, resulting in the surrounding environment being polluted by debris and affecting the health of subsequent operators. Summary of the Utility Model

[0004] In order to overcome the deficiencies of the prior art, the utility model provides an end grinder for stainless steel pipes, which can solve the technical problems that in the existing end grinder for stainless steel pipes, when the user holds the handle to control the main body of the device to polish the steel pipe, due to the rotation of the motor driving the polishing plate to polish the steel pipe, a large vibration will be generated. When the user holds the handle, the vibration generated by the protective sleeve will be buffered by squeezing the second spring, so that the user's hand is not easily paralyzed due to long-term vibration when using this device for a long time. And the sound-absorbing cotton can absorb the noise generated when the polishing plate polishes the steel pipe, improving the environmental protection. However, since a large amount of dust and other debris will be generated during the polishing of stainless steel pipes, and most of the current end grinders for stainless steel pipes do not have a dust adsorption and purification structure, the dust generated during polishing will spread in the surrounding environment, resulting in the surrounding environment being polluted by debris and affecting the health of subsequent operators.

[0005] To solve the above technical problems, the present utility model provides the following technical solutions: A end grinding machine for stainless steel pipes, comprising a machine body. One side of the top of the machine body is provided with an air extraction hole, and the bottom of the air extraction hole is communicated with a filter chamber.

A suction fan is fixedly installed inside the fixing seat. One side of the fixing seat is fixedly connected with a partition board. A storage structure is arranged inside the top of the machine body.

[0006] As a preferred technical solution of the present utility model, the storage structure includes a storage chamber and a guide groove. The storage chamber is arranged inside the top of the machine body, and one side of the storage chamber is communicated with the guide groove.

[0007] As a preferred technical solution of the present utility model, a cylinder is arranged inside the storage chamber, and the other end of the cylinder is fixedly connected with a lifting seat. A guide block is fixedly installed on the side wall of the lifting seat, and a limit seat is arranged at the top of the guide block. A protective pad is arranged on the inner side wall of the limit seat.

[0008] As a preferred technical solution of the present utility model, a support rod is fixedly connected to one side of the top of the machine body, and a motor is fixedly installed on one side of the top of the support rod. The output end of the motor is connected with a grinding wheel.

[0009] As a preferred technical solution of the present utility model, the air extraction holes are equidistantly distributed along both sides of the top of the machine body, and the air extraction holes and the machine body form an integral structure.

[0010] As a preferred technical solution of the present utility model, the lifting seat is slidably connected with the machine body through the guide block, and the guide blocks are symmetrically distributed along the vertical center line of the machine body.

[0011] Compared with the prior art, the beneficial effects that the present utility model can achieve are:

[0012] 1. By using the provided filter cotton board, honeycomb adsorption board and activated carbon board, it is convenient to subsequently carry out sufficient filtration and purification treatment on the extracted air doped with waste chips, thereby effectively preventing the waste chips generated during grinding from spreading in the surrounding environment and causing pollution to the surrounding environment. When the suction fan works, the air doped with waste chips is drawn into the inside of the machine body and undergoes preliminary filtration and adsorption treatment through the filter cotton board.

An air extraction hole 2 is opened on one side of the top of the machine body 1, and a filter cavity 3 is communicated with the bottom of the air extraction hole 2. An air outlet hole 4 is opened on the surface of the machine body 1. A filter cotton plate 5 is arranged inside the filter cavity 3, and a honeycomb adsorption plate 6 is distributed below the filter cotton plate 5. The other side of the honeycomb adsorption plate 6 is distributed with an activated carbon plate 7, and a fixing seat 8 is distributed on the side of the activated carbon plate 7 away from the honeycomb adsorption plate 6. A suction fan 9 is fixedly installed inside the fixing seat 8. One side of the fixing seat 8 is fixedly connected with a partition plate 10. A storage structure is arranged inside the top of the machine body 1. A support rod 18 is fixedly connected to one side of the top of the machine body 1, and a motor 19 is fixedly installed on one side of the top of the support rod 18. The output end of the motor 19 is connected with a grinding wheel 20;

[0022] The motors 19 are symmetrically distributed along the vertical center line of the machine body 1, and the two motors 19 on both sides work independently, and the motors 19 are all electrically connected to an external power supply through wires;

[0023] During use, first adjust the lifting seat 14 to an appropriate height, and then pass the stainless steel pipe through the inside of the limit seat 16. Then the motor 19 works and the grinding wheel 20 connected to its output end rotates accordingly, and then the grinding process of the stainless steel pipe can be realized;

[0024] As a further implementation manner of this embodiment, as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, an air extraction hole 2 is opened on one side of the top of the machine body 1, and a filter cavity 3 is communicated with the bottom of the air extraction hole 2. The air extraction holes 2 are equidistantly distributed along both sides of the top of the machine body 1, and the air extraction holes 2 and the machine body 1 form an integrated structure. An air outlet hole 4 is opened on the surface of the machine body 1. A filter cotton plate 5 is arranged inside the filter cavity 3, and a honeycomb adsorption plate 6 is distributed below the filter cotton plate 5. The other side of the honeycomb adsorption plate 6 is distributed with an activated carbon plate 7, and a fixing seat 8 is distributed on the side of the activated carbon plate 7 away from the honeycomb adsorption plate 6. A suction fan 9 is fixedly installed inside the fixing seat 8. One side of the fixing seat 8 is fixedly connected with a partition plate 10. A storage structure is arranged inside the top of the machine body 1. The storage structure includes a storage cavity 11 and a guide groove 12. The storage cavity 11 is opened inside the top of the machine body 1. One side of the storage cavity 11 is communicated with the guide groove 12. A cylinder 13 is arranged inside the storage cavity 11, and the other end of the cylinder 13 is fixedly connected with a lifting seat 14. The lifting seat 14 is slidably connected with the machine body 1 through a guide block 15, and the guide blocks 15 are symmetrically distributed along the vertical center line of the machine body 1. A guide block 15 is fixedly installed on the side wall of the lifting seat 14, and a limit seat 16 is arranged at the top of the guide block 15. A protective pad 17 is arranged on the inner side wall of the limit seat 16;

[0025] During use, the cylinder 13 works to longitudinally push the lifting seat 14 fixedly connected to its top end. Then, the lifting seat 14 drives the limit seat 16 fixedly installed at its top end to move longitudinally accordingly, so as to facilitate subsequent limit support treatment for the stainless steel pipe. At the same time, when the lifting seat 14 moves longitudinally, the guide block 15 will slide along the guide groove 12, thereby improving the stability of the lifting seat 14 during longitudinal movement. When waste chips are generated during the grinding of the stainless steel pipe, the exhaust fan 9 works to draw the air mixed with waste chips from the outside into the inner side of the filter chamber 3 through the air extraction holes 2. Subsequently, the air is preliminarily filtered and purified by the provided filter cotton plate 5. Then, the honeycomb adsorption plate 6 is used to further remove the impurities mixed in the air. Finally, the activated carbon plate 7 is used to perform the final filtration and purification treatment on the air. Subsequently, the treated air will be output through the grid slots opened at the bottom of the partition plate 10, facilitating subsequent discharge through the air outlet holes 4, thereby effectively preventing the waste chips generated during the grinding of the stainless steel pipe from polluting the surrounding environment;

[0026] Specific working principle:

[0027] The cylinder 13 works to longitudinally push the lifting seat 14 fixedly connected to its top end. Then, the lifting seat 14 drives the limit seat 16 fixedly installed at its top end to move longitudinally accordingly, so as to facilitate subsequent limit support treatment for the stainless steel pipe. Immediately afterwards, the motor 19 works to drive the grinding wheel 20 connected to its output end to rotate accordingly, thereby realizing the grinding treatment of the stainless steel pipe. At the same time, when the lifting seat 14 moves longitudinally, the guide block 15 will slide along the guide groove 12, thereby improving the stability of the lifting seat 14 during longitudinal movement. When waste chips are generated during the grinding of the stainless steel pipe, the exhaust fan 9 works to draw the air mixed with waste chips from the outside into the inner side of the filter chamber 3 through the air extraction holes 2. Subsequently, the air is preliminarily filtered and purified by the provided filter cotton plate 5. Then, the honeycomb adsorption plate 6 is used to further remove the impurities mixed in the air. Finally, the activated carbon plate 7 is used to perform the final filtration and purification treatment on the air. Subsequently, the treated air will be output through the grid slots opened at the bottom of the partition plate 10, facilitating subsequent discharge through the air outlet holes 4, thereby effectively preventing the waste chips generated during the grinding of the stainless steel pipe from polluting the surrounding environment.
