Description

Technical Field

[0001] The present application relates to the field of pipe rust removal, and in particular to a pipe grinding machine. Background Art

[0002] In the related art, the pipe grinder is used to remove rust from the outer wall of the pipe. The operator puts the pipe into the pipe grinder, which conveys and grinds the outer wall of the pipe in a preset direction. Then, the operator takes out the pipe at the discharge end of the pipe grinder and visually checks to ensure that the rust has been completely removed. If the rust is not completely removed, the pipe needs to be put back into the grinder for further processing. This processing method reduces the processing efficiency of the pipe, and the operator is prone to fatigue due to long-term work, which may lead to missed inspections, resulting in the mixing of pipes with incompletely rusted pipes into the cleaned pipes, which in turn affects the product quality of the pipes.

[0029] The following is combined with Figure 1-Figure 7 This application is described in further detail.

[0030] The embodiment of the present application discloses a pipe grinding machine 100 .

[0031] Reference Figure 1 and Figure 2 According to the embodiment of the present application, the pipe grinding machine 100 includes: a mounting platform 1, a conveying mechanism 2, a rust detection component 3, a controller and a grinding component 4. The grinding component 4 is arranged on the mounting platform 1, and the grinding component 4 is used to grind the outer peripheral wall of the pipe. Specifically, the grinding component 4 includes a grinding wheel and a motor. The motor is installed on the mounting platform 1, and the grinding wheel is connected and matched with the motor. The motor is used to drive the grinding wheel to rotate around the central axis of the grinding wheel. The grinding wheel is suitable for abutting against the outer peripheral wall of the pipe, and the grinding wheel is used to grind the rust on the outer peripheral wall of the pipe.

[0032] In some specific embodiments, the grinding wheel is preferably a grinding wheel.

[0033] The conveying mechanism 2 includes a power roller 21, a plurality of conveying wheels 22 and a first driving member 23. The power roller 21 and the plurality of conveying wheels 22 are pivotally mounted on the mounting platform 1. The plurality of conveying wheels 22 are arranged in sequence along the first direction of the mounting platform 1. The plurality of conveying wheels 22 and the power roller 21 are spaced apart and arranged along the second direction of the mounting platform 1. The plurality of conveying wheels 22 and the power roller 21 are arranged relatively to each other. The pipe fitting is movably clamped between the plurality of conveying wheels 22 and the power roller 21. Specifically, the outer peripheral wall of the pipe fitting is stopped against the power roller 21 and the plurality of conveying wheels 22. The pipe fitting is suitable for moving leftward or rightward along the first direction of the mounting platform 1, and the pipe fitting is suitable for rotating around the central axis of the pipe fitting. The first direction of the mounting platform 1 can refer to Figure 1 The left and right directions in the figure, the second direction of the mounting platform 1 can refer to Figure 1 The front-to-back direction.

[0034] In some specific embodiments, a plurality of conveying wheels 22 may also be sequentially spaced apart and arranged along the first direction of the mounting platform 1 .

[0035] There is a preset angle between the central axis of each conveying wheel 22 and the central axis of the power roller 21, and multiple conveying wheels 22 are tilted toward the same side, that is, multiple conveying wheels 22 can tilt toward the left side at the same time, or multiple conveying wheels 22 can tilt toward the right side at the same time.

[0036] In some specific embodiments, the preset angle of the angle between the central axis of each conveying wheel 22 and the central axis of the power roller 21 can be 30°, but the present application is not limited to this. The preset angle of the angle between the central axis of each conveying wheel 22 and the central axis of the power roller 21 can be 45°, etc.

[0037] In addition, the first driving member 23 is transmission-connected with the power roller 21 and is suitable for being transmission-connected with multiple conveying wheels 22. The first driving member 23 is used to drive the power roller 21 to drive the pipe to rotate around the central axis of the pipe, and the pipe is suitable for driving multiple conveying wheels 22 to rotate around the central axis of the conveying wheel 22. The conveying wheel 22 is used to convey the pipe. Specifically, the first driving member 23 drives the power roller 21 to rotate, the power roller 21 drives the pipe to rotate around the central axis of the pipe, and then the pipe drives the conveying wheel 22 to rotate around the central axis of the conveying wheel 22. The conveying wheel 22 applies a driving force to the pipe, and the direction of the driving force has an angle with the central axis of the pipe. The driving force can be split into a component force toward the axial direction of the pipe and a component force toward the radial direction of the pipe. The component force toward the axial direction of the pipe drives the pipe to move along the first direction of the mounting platform 1, thereby achieving the technical effect of conveying the pipe by the conveying wheel 22.

[0038] Furthermore, the angle between the direction of the driving force and the central axis of the pipe is equal to the angle between the central axis of the conveying wheel 22 and the central axis of the power roller 21 .

[0039] The first driving member 23 is also used to drive the multiple conveying wheels 22 to rotate around the pivot axis between the conveying wheel 22 and the mounting platform 1 to adjust the conveying direction of the pipe. Specifically, the first driving member 23 drives the multiple conveying wheels 22 to rotate left or right around the pivot axis between the conveying wheel 22 and the mounting platform 1. When the multiple conveying wheels 22 all rotate to the left, the multiple conveying wheels 22 convey the pipe from right to left. When the multiple conveying wheels 22 all rotate to the right, the multiple conveying wheels 22 convey the pipe from left to right.

[0040] In some specific embodiments, the first driving member 23 is preferably a motor.

[0041] In addition, the rust detection member 3 is arranged on the mounting platform 1 and is used to detect rust on the outer peripheral wall of the pipe. Specifically, along the height direction of the mounting platform 1, the rust detection member 3 is located above the pipe, and the rust detection member 3 is located on the left side of the grinding assembly 4. The pipe enters the pipe grinding machine 100 from the right side of the mounting platform 1, and the conveying mechanism 2 conveys the pipe from right to left. The rust detection member 3 and the first driving member 23 are both connected to the controller for communication. The controller is used to control the first driving member 23 to drive the plurality of conveying wheels 22 to rotate according to the detection signal of the rust detection member 3. The height direction of the mounting platform 1 can refer to Figure 1 The up and down directions in .

[0042] When the first driving member 23 does not drive the multiple conveying wheels 22 to rotate around the pivot axis between the conveying wheels 22 and the mounting table 1, the multiple conveying wheels 22 are all tilted toward the left side. After the grinding assembly 4 completes grinding the outer peripheral wall of the pipe fitting, the rust detection member 3 detects whether there is rust on the outer peripheral wall of the pipe fitting. When there is no rust on the outer peripheral wall of the pipe fitting, the controller controls the first driving member 23 not to drive the multiple conveying wheels 22 to rotate according to the detection signal of the rust detection member 3. In other words, the multiple conveying wheels 22 convey the pipe fittings from right to left, and the grinding assembly 4 only grinds the pipe fittings once.

[0043] When rust exists on the outer wall of the pipe fitting, the controller controls the first driving member 23 to drive the multiple conveying wheels 22 to rotate toward the right according to the detection signal of the rust detection member 3, and the multiple conveying wheels 22 convey the pipe fitting from left to right. The grinding assembly 4 re-grinds the outer wall of the pipe fitting to remove the rust on the outer wall of the pipe fitting.

[0044] Furthermore, after the pipe is polished for the second time, the first driving member 23 drives the plurality of conveying wheels 22 to rotate toward the left side.

[0045] In some specific embodiments, the rust detection component 3 may be a CCD (Charge-Coupled Device camera) camera, but the present application is not limited thereto. The rust detection component 3 may also be an electromagnetic sensor or the like.

[0046] It should be noted that the electromagnetic sensor applies an alternating magnetic field to the pipe, which will generate an induced current inside the pipe. The induced current will generate a magnetic field. The electromagnetic sensor identifies whether there is rust on the pipe by identifying the magnetic field generated by the induced current. When there is rust on the pipe, the rust will change the magnetic permeability or electrical conductivity of the pipe, thereby changing the size of the induced current.

[0047] Thus, by using the rust detection member 3 to detect whether there is rust on the outer peripheral wall of the pipe fitting, when there is rust on the outer peripheral wall of the pipe fitting, the controller controls the first driving member 23 to drive the multiple conveying wheels 22 to rotate toward the right, and the multiple conveying wheels 22 convey the pipe fitting from left to right, and the grinding assembly 4 re-grinds the outer peripheral wall of the pipe fitting. Compared with the prior art, the operator does not need to re-send the pipe fitting into the pipe fitting grinding machine 100, thereby improving the processing efficiency of the pipe fitting, and avoiding the operator's missed inspection, resulting in the mixing of the pipe fitting with the rust not completely removed into the cleaned pipe fitting, thereby improving the product quality of the pipe fitting.

[0048] Reference Figure 2-Figure 4 In some embodiments of the present application, the conveying mechanism 2 also includes a reversing member 24, which is slidably arranged on the mounting platform 1, and the reversing member 24 is suitable for being connected to the first driving member 23 in transmission. The conveying wheel 22 includes a conveying portion 221 and a connecting frame 222, and the connecting frame 222 is pivotally connected to the mounting platform 1. The conveying portion 221 is pivotally connected to the connecting frame 222, and the conveying portion 221 is used to convey pipe fittings. Specifically, there is an angle of preset angle between the central axis of the conveying portion 221 and the central axis of the power roller 21, and the power roller 21 drives the pipe fitting to drive the conveying portion 221 to rotate around the pivot axis between the conveying portion 221 and the connecting frame 222, and the conveying portion 221 conveys the pipe fittings along the first direction of the mounting platform 1.

[0049] The reversing member 24 is transmission-connected to the connecting frame 222, and the first driving member 23 is used to drive the reversing member 24 to drive the connecting frame 222 to rotate around the pivot axis between the connecting frame 222 and the mounting platform 1. Specifically, the first driving member 23 drives the reversing member 24 to move leftward to drive multiple connecting frames 222 to rotate leftward around the pivot axis between the connecting frame 222 and the mounting platform 1, or the first driving member 23 drives the reversing member 24 to move rightward to drive multiple connecting frames 222 to rotate rightward around the pivot axis between the connecting frame 222 and the mounting platform 1. The connecting frame 222 drives the corresponding conveying part 221 to rotate leftward or rightward, and the conveying part 221 conveys the pipe fittings to the left or right, thereby achieving the technical effect of adjusting the conveying direction of the pipe fittings by the conveying part 221.

[0050] Reference Figure 2-Figure 4 In some embodiments of the present application, the connecting frame 222 is provided with a waist-shaped hole 2221, and the waist-shaped hole 2221 is constructed as a through hole. The switching member 24 is provided with a plurality of driving protrusions 241 arranged in sequence along the first direction of the mounting platform 1. The plurality of driving protrusions 241 and the plurality of waist-shaped holes 2221 are arranged in one-to-one correspondence and are transmission connected. The driving protrusions 241 extend into the corresponding waist-shaped holes 2221 and are transmission connected with the corresponding waist-shaped holes 2221.

[0051] Specifically, the driving protrusion 241 is slidably set in the corresponding waist-shaped hole 2221. Along the first direction of the mounting table 1, when the multiple connecting frames 222 drive the corresponding conveying parts 221 to rotate to the left, the first driving member 23 drives the reversing member 24 to drive the multiple driving protrusions 241 to move to the left, and the driving protrusion 241 stops at the left side wall of the corresponding waist-shaped hole 2221, and drives the connecting frame 222 through the waist-shaped hole 2221 to drive the conveying part 221 to rotate to the left.

[0052] When multiple connecting frames 222 drive the corresponding conveying parts 221 to rotate to the right, the first driving member 23 drives the reversing member 24 to drive multiple driving protrusions 241 to move to the right, and the driving protrusions 241 stop against the right side wall of the corresponding waist-shaped hole 2221, and the connecting frame 222 is driven through the waist-shaped hole 2221 to drive the conveying part 221 to rotate to the right, thereby achieving the technical effect of driving the connecting frame 222 to rotate through the reversing member 24.

[0053] In some specific embodiments, a plurality of driving protrusions 241 may be disposed at intervals along the first direction of the mounting table 1 .

[0054] Reference Figure 2-Figure 4 In some embodiments of the present application, a first output gear 231 is provided at the output end of the first driving member 23, and a driving rack 242 is provided at the reversing member 24. Along the height direction of the mounting platform 1, the first output gear 231 and the driving rack 242 are arranged opposite to each other and spaced apart and are suitable for meshing connection, and the first output gear 231 is located above the driving rack 242.

[0055] The mounting platform 1 is provided with a second driving member 11, which is transmission-connected to the reversing member 24. The second driving member 11 is used to drive the reversing member 24 to drive the driving rack 242 to move close to the first output gear 231. The second driving member 11 is communication-connected to the controller, and the controller is also used to control the second driving member 11 to start or stop according to the detection signal of the rust detection member 3.

[0056] Specifically, when the grinding assembly 4 completes grinding the outer wall of the pipe and there is rust on the outer wall of the pipe, the controller controls the second driving member 11 to drive the reversing member 24 to drive the driving rack 242 to move close to the first output gear 231 according to the detection signal of the rust detection member 3. The driving rack 242 is meshed and connected with the first output gear 231. The first driving member 23 drives the reversing member 24 through the first output gear 231 to drive multiple connecting frames 222 to rotate. The connecting frames 222 drive the corresponding conveying parts 221 to rotate, thereby achieving the technical effect of driving the reversing member 24 to move by the first driving member 23.

[0057] Furthermore, when the connecting frame 222 drives the conveying part 221 to rotate to a preset angle, the second driving member 11 stops working, and under the action of gravity, the reversing member 24 drives the driving rack 242 to move away from the first output gear 231, and the driving rack 242 and the first output gear 231 are separated. When the first driving member 23 drives the power roller 21 to rotate, the first driving member 23 will not drive the connecting frame 222 to rotate, thereby preventing the connecting frame 222 from rotating continuously, and preventing the conveying part 221 from being unable to transport the pipe to the grinding assembly 4.

[0058] When the grinding assembly 4 finishes grinding the outer peripheral wall of the pipe and there is no rust on the outer peripheral wall of the pipe, the controller controls the second driving member 11 to stop working according to the detection signal of the rust detection member 3.

[0059] It should be noted that the connecting frame 222 is located above the reversing member 24 , and the upper end wall of the reversing member 24 and the connecting frame 222 are spaced apart from each other.

[0060] In some specific embodiments, the second driving member 11 is preferably an electromagnet.

[0061] Reference Figure 2 and Figure 4 In some embodiments of the present application, the mounting platform 1 is provided with a guide groove 12, which is configured as a through groove. The guide groove 12 is extended along the first direction of the mounting platform 1, and the reversing member 24 is slidably disposed in the guide groove 12 and guidedly cooperates with the guide groove 12. Through the guiding cooperation between the reversing member 24 and the guide groove 12, the reversing member 24 can be prevented from deviating from the preset track, and the reversing member 24 can be prevented from failing to drive the connecting frame 222 to rotate, thereby improving the working reliability of the pipe grinding machine 100.

[0062] Reference Figure 3 and Figure 4 In some embodiments of the present application, the outer peripheral wall of the switching member 24 is provided with a first stop portion 243 and a second stop portion 244. Along the height direction of the mounting platform 1, the first stop portion 243 and the second stop portion 244 are spaced apart from each other, the switching member 24 passes through the guide groove 12, and the guide groove 12 is located between the first stop portion 243 and the second stop portion 244.

[0063] The first stop portion 243 is suitable for limiting cooperation with one end wall of the guide groove 12, and the second stop portion 244 is suitable for limiting cooperation with the other end wall of the guide groove 12. Specifically, the first stop portion 243 is opposite to the upper end wall of the guide groove 12, and the second stop portion 244 is opposite to the lower end wall of the guide groove 12. When the reversing member 24 is not driven by the second driving member 11, the first stop portion 243 is limited to cooperate with the upper end wall of the guide groove 12, thereby preventing the reversing member 24 from falling downward and separating from the guide groove 12, and preventing the guide groove 12 from being unable to guide the reversing member 24, thereby further improving the working reliability of the pipe grinding machine 100.

[0064] When the reversing member 24 is driven by the second driving member 11, the second stop portion 244 cooperates with the lower end wall of the guide groove 12 to prevent the reversing member 24 from extending out of the guide groove 12, and prevent the reversing member 24 from deviating from the preset motion trajectory when the first driving member 23 drives the reversing member 24 to move. It can also prevent the reversing member 24 from being unable to drive the connecting frame 222 to rotate to a preset angle, thereby further improving the working reliability of the pipe grinding machine 100.

[0065] In some specific embodiments, the first stop portion 243 and the second stop portion 244 are both disposed around the outer peripheral wall of the switching member 24 .

[0066] Reference Figure 2 , Figure 5 and Figure 6 In some embodiments of the present application, the pipe grinding machine 100 may further include: a locking assembly 5, wherein two accommodating holes 121 are provided on one side wall of the guide groove 12 along the second direction of the mounting table 1, and the two accommodating holes 121 are spaced apart along the first direction of the mounting table 1, and wherein one of the two accommodating holes 121 is provided close to the left side wall of the guide groove 12, and the other accommodating hole 121 is provided close to the right side wall of the guide groove 12 along the first direction of the mounting table 1, and the reversing member 24 is slidably provided between the two accommodating holes 121, and wherein a locking portion 245 is provided at one end and the other end of the reversing member 24 along the first direction of the mounting table 1, that is, a locking portion 245 is provided at both the left end portion and the right end portion of the reversing member 24.

[0067] A locking assembly 5 is provided in each accommodating hole 121, and the locking assembly 5 includes an elastic member 51 and a locking member 52. The locking member 52 is movably arranged in the accommodating hole 121 and is suitable for abutting against the other side wall of the guide groove 12. Specifically, the accommodating hole 121 is located at the rear end wall of the guide groove 12, and the end of the locking member 52 away from the accommodating hole 121 is suitable for abutting against the front end wall of the guide groove 12. The elastic member 51 is elastically deformably arranged between the bottom wall of the accommodating hole 121 and the locking member 52, and a locking gap 521 is defined between the locking member 52 and the end wall of the guide groove 12. Specifically, a locking gap 521 is defined between the locking member 52 in the accommodating hole 121 close to the left side wall of the guide groove 12 and the left side wall of the guide groove 12, and a locking gap 521 is defined between the locking member 52 in the accommodating hole 121 close to the right side wall of the guide groove 12 and the right side wall of the guide groove 12.

[0068] The locking portion 245 is suitable for extending into the locking gap 521 and lockingly cooperating with the locking member 52 . The locking portion 245 is used to drive the locking member 52 to extend into the receiving hole 121 , and the elastic member 51 is used to drive the locking member 52 to extend out of the receiving hole 121 .

[0069] Specifically, when the first driving member 23 drives the reversing member 24 to move to the left, the locking portion 245 located at the left end of the reversing member 24 stops against the locking member 52 located on the left side of the reversing member 24, and the locking portion 245 drives the locking member 52 to extend into the accommodating hole 121. The locking portion 245 extends into the locking gap 521 and separates from the locking member 52. The elastic member 51 drives the locking member 52 to extend out of the accommodating hole 121, and the second driving member 11 stops working. The reversing member 24 moves away from the first output gear 231, and the locking member 52 is locked with the locking portion 245, thereby preventing the reversing member 24 from moving to the right to change the conveying direction of the pipe when the grinding assembly 4 is grinding the pipe, thereby improving the working reliability of the pipe grinding machine 100.

[0070] When the first driving member 23 drives the reversing member 24 to move rightward, the locking portion 245 located at the left end of the reversing member 24 abuts against the locking member 52 located on the left side of the reversing member 24, and the locking portion 245 drives the locking member 52 to extend into the accommodating hole 121, and the locking portion 245 located at the left end of the reversing member 24 moves out of the locking gap 521.

[0071] When the reversing member 24 moves to the right to a preset position, the locking portion 245 located at the right end of the reversing member 24 stops against the locking member 52 located on the right side of the reversing member 24, and the locking portion 245 located at the right end of the reversing member 24 drives the locking member 52 to extend into the accommodating hole 121. The locking portion 245 located at the right end of the reversing member 24 extends into the locking gap 521 and separates from the locking member 52. The elastic member 51 drives the locking member 52 to extend out of the accommodating hole 121, and the second driving member 11 stops working. The reversing member 24 moves away from the first output gear 231, and the locking member 52 is locked with the locking portion 245.

[0072] It should be noted that the elastic force of the elastic member 51 is relatively large, and only when the first driving member 23 drives the reversing member 24 to drive the locking portion 245 to move, can the locking portion 245 drive the locking member 52 to extend into the accommodating hole 121 .

[0073] In some specific embodiments, the elastic member 51 is preferably a spring.

[0074] Reference Figure 6 and Figure 7 In some embodiments of the present application, a driving bevel 522 is provided at the end of the locking member 52 away from the accommodating hole 121. Along the second direction of the mounting platform 1, the driving bevel 522 is located at the front end of the locking member 52. The driving bevel 522 is inclined toward the central axis of the locking member 52. The locking portion 245 is suitable for moving along the driving bevel 522 to drive the locking member 52 to extend into the accommodating hole 121.

[0075] Specifically, when the locking portion 245 extends into the locking gap 521, the locking portion 245 abuts against the driving inclined surface 522, and the locking portion 245 moves along the driving inclined surface 522 close to the locking gap 521 and drives the locking member 52 to extend into the accommodating hole 121, thereby achieving the technical effect that the locking portion 245 drives the locking member 52 to move and extend into the locking gap 521.

[0076] When the locking portion 245 moves out of the locking gap 521 , the locking portion 245 abuts against the driving inclined surface 522 , and the locking portion 245 moves along the driving inclined surface 522 away from the locking gap 521 and drives the locking member 52 to extend into the accommodating hole 121 , so that the reversing member 24 drives the locking portion 245 to move out of the locking gap 521 .

[0077] Reference Figure 1 and Figure 2In some embodiments of the present application, there are multiple rust detection members 3, and the multiple rust detection members 3 are arranged in sequence along the first direction of the mounting platform 1. In some specific embodiments, there are two rust detection members 3, one of the two rust detection members 3 is located on the left side of the grinding assembly 4, and the other is located on the right side of the grinding assembly 4. When the outer peripheral wall of the pipe is firstly ground, the conveying direction of the pipe is from right to left. When the pipe is firstly ground, the rust detection member 3 located on the left side of the grinding assembly 4 detects whether there is rust on the outer peripheral wall of the pipe. When there is rust on the outer peripheral wall of the pipe, the controller controls the first driving member 23 to drive the reversing member 24 to drive the multiple conveying wheels 22 to rotate to adjust the conveying direction of the pipe. The conveying mechanism 2 conveys the pipe from left to right, and the grinding assembly 4 performs secondary grinding on the pipe.

[0078] When the pipe has completed the second grinding, the rust detection component 3 located on the right side of the grinding component 4 detects whether there is rust on the outer wall of the pipe. When rust is present on the outer wall of the pipe, the controller controls the first driving component 23 to drive the reversing component 24 to drive the multiple conveying wheels 22 to rotate to adjust the conveying direction of the pipe. The conveying mechanism 2 conveys the pipe from right to left, and the grinding component 4 grinds the pipe three times. The pipe grinding machine 100 is configured in this way to grind the pipe multiple times to remove rust on the outer wall of the pipe as much as possible, thereby improving the user experience of the pipe grinding machine 100.

[0079] Reference Figure 1 In some embodiments of the present application, a second output gear 232 is provided at the output end of the first driving member 23, and an input gear 211 is provided at the left end of the power roller 21 along the first direction of the mounting platform 1, and the second output gear 232 is meshedly connected with the input gear 211.

[0080] Through the meshing connection between the second output gear 232 and the input gear 211, the first driving member 23 drives the second output gear 232 to drive the input gear 211 to rotate, and the input gear 211 drives the power roller 21 to rotate around the central axis of the power roller 21, thereby achieving the technical effect of the first driving member 23 driving the power roller 21 to rotate.

[0081] In some specific embodiments, both the second output gear 232 and the input gear 211 may be configured as bevel gears.

[0082] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
