Description

Technical Field

[0001] This application relates to the field of rust removal of pipe fittings, and in particular to a pipe fitting grinding machine. Background Technology

[0002] In related technologies, pipe grinding machines are used to remove rust from the outer walls of pipe fittings. Operators place the pipe fittings into the grinding machine, which then conveys and grinds the outer walls along a preset direction. Afterward, the operator removes the pipe fitting from the discharge end of the machine and visually inspects it to ensure that the rust has been completely removed. If the rust is not completely removed, the pipe fitting needs to be put back into the grinding machine for further processing. This processing method reduces the efficiency of pipe fitting processing, and operators are prone to fatigue from prolonged work, which may lead to missed inspections. Consequently, pipe fittings with incompletely removed rust may be mixed with cleaned pipe fittings, thus affecting the product quality. Summary of the Invention

[0003] In order to improve the processing efficiency of pipe fittings and to prevent pipe fittings with incomplete rust removal from being mixed into cleaned pipe fittings due to operator oversight, thereby improving the product quality of pipe fittings, this application provides a pipe fitting grinding machine.

[0004] The pipe grinding machine provided in this application adopts the following technical solution: A pipe grinding machine includes: a mounting platform; and a conveying mechanism, the conveying mechanism including a power roller, a plurality of conveying wheels, and a first driving member. The power roller and the plurality of conveying wheels are pivotally mounted on the mounting platform. The plurality of conveying wheels are arranged sequentially along a first direction of the mounting platform. The plurality of conveying wheels and the power roller are arranged opposite to each other. A pipe is movably clamped between the plurality of conveying wheels and the power roller. The central axis of each conveying wheel and the central axis of the power roller have a preset angle. The first driving member is driven to drive the power roller and is adapted to be driven to drive the plurality of conveying wheels. The first driving member is used to drive the power roller to rotate the pipe around the central axis of the pipe, and the pipe is adapted to drive the plurality of conveying wheels to rotate around the central axis of the conveying wheels. The conveying wheels are used to convey the pipe. The first driving member is also used to drive the plurality of conveying wheels to rotate around the pivot axis between the conveying wheels and the mounting platform to adjust the conveying direction of the pipe.

[0005] A rust detection device is disposed on the mounting platform and used to detect rust on the outer peripheral wall of the pipe fitting; a controller is configured to communicate with both the rust detection device and the first drive unit, and the controller is configured to control the first drive unit to drive the multiple conveying wheels to rotate according to the detection signal of the rust detection device.

[0006] A grinding assembly is provided on the mounting platform and is used to grind the outer peripheral wall of the pipe fitting.

[0007] By adopting the above technical solution, a rust detection component is used to detect the presence of rust on the outer wall of the pipe fitting. When rust is found, the controller controls the first drive component to rotate multiple conveyor wheels to the right. The multiple conveyor wheels transport the pipe fitting from left to right, and the grinding component re-grinds the outer wall of the pipe fitting. Compared with existing technologies, operators do not need to refeed the pipe fitting into the pipe fitting grinding machine, thereby improving the processing efficiency of the pipe fittings. Furthermore, it avoids operators missing inspections, leading to pipe fittings with incompletely removed rust being mixed into cleaned pipe fittings, thus improving the product quality of the pipe fittings.

[0008] Preferably, the conveying mechanism further includes a reversing component, which is slidably disposed on the mounting platform. The reversing component is adapted to be drivenly connected to the first driving component. The conveying wheel includes a conveying part and a connecting frame. The connecting frame is pivotally connected to the mounting platform, and the conveying part is pivotally connected to the connecting frame. The conveying part is used to convey the pipe fitting. The reversing component is drivenly connected to the connecting frame. The first driving component is used to drive the reversing component to drive the connecting frame to rotate around the pivot axis between the connecting frame and the mounting platform.

[0009] By adopting the above technical solution, the first driving component drives the reversing component to move to the left, thereby causing multiple connecting frames to rotate to the left around the pivot axis between the connecting frame and the mounting platform, or the first driving component drives the reversing component to move to the right, thereby causing multiple connecting frames to rotate to the right around the pivot axis between the connecting frame and the mounting platform. The connecting frame drives the corresponding conveying part to rotate to the left or right, and the conveying part conveys the pipe fittings to the left or right, thereby achieving the technical effect of adjusting the conveying direction of the pipe fittings through the conveying part.

[0010] Preferably, the connecting frame is provided with an oblong hole, and the reversing component is provided with a plurality of driving protrusions arranged sequentially along the first direction of the mounting platform. The plurality of driving protrusions and the plurality of oblong holes are arranged in a one-to-one correspondence and are connected in transmission. The driving protrusions extend into the corresponding oblong holes and are connected in transmission with the corresponding oblong holes.

[0011] By adopting the above technical solution, when multiple connecting frames drive the corresponding conveying parts to rotate to the left, the first driving member drives the reversing member to move multiple driving protrusions to the left. The driving protrusions abut against the left side wall of the corresponding oblong hole, driving the connecting frames through the oblong hole to rotate the conveying parts to the left. Furthermore, when multiple connecting frames drive the corresponding conveying parts to rotate to the right, the first driving member drives the reversing member to move multiple driving protrusions to the right. The driving protrusions abut against the right side wall of the corresponding oblong hole, driving the connecting frames through the oblong hole to rotate the conveying parts to the right. This achieves the technical effect of driving the connecting frames to rotate through the reversing member.

[0012] Preferably, the first drive member has a first output gear at its output end, and the reversing member has a drive rack. Along the height direction of the mounting platform, the first output gear and the drive rack are opposite to each other and spaced apart and are adapted to mesh with each other. The mounting platform has a second drive member, which is connected to the reversing member in a transmission manner. The second drive member is used to drive the reversing member to move the drive rack closer to the first output gear. The second drive member is communicatively connected to the controller. The controller is also used to control the second drive member to start or stop according to the detection signal of the rust detection member.

[0013] By adopting the above technical solution, when the grinding component completes the grinding of the outer peripheral wall of the pipe and there is rust on the outer peripheral wall of the pipe, the controller controls the second driving component to drive the reversing component to move the driving rack close to the first output gear according to the detection signal of the rust detection component. The driving rack meshes with the first output gear, and the first driving component drives the reversing component to rotate multiple connecting frames through the first output gear. The connecting frames drive the corresponding conveying parts to rotate, thereby achieving the technical effect of driving the reversing component to move through the first driving component.

[0014] Preferably, the mounting platform is provided with a guide groove, the guide groove extends along a first direction of the mounting platform, and the reversing member is slidably disposed in the guide groove and guides and cooperates with the guide groove.

[0015] By adopting the above technical solution, the reversing component and the guide groove are coordinated to prevent the reversing component from deviating from the preset track and to prevent the reversing component from failing to drive the connecting frame to rotate, thereby improving the working reliability of the pipe grinding machine.

[0016] Preferably, the outer peripheral wall of the reversing member is provided with a first stop portion and a second stop portion. The first stop portion and the second stop portion are spaced apart along the height direction of the mounting platform. The guide groove is located between the first stop portion and the second stop portion. The first stop portion is adapted to limit the engagement with one end wall of the guide groove, and the second stop portion is adapted to limit the engagement with the other end wall of the guide groove.

[0017] By adopting the above technical solution, when the reversing component is not driven by the second driving component, the first stop portion engages with the upper end wall of the guide groove to limit its movement, thereby preventing the reversing component from falling downwards and separating from the guide groove. This also prevents the guide groove from failing to guide the reversing component, further improving the operational reliability of the pipe grinding machine. Furthermore, when the reversing component is driven by the second driving component, the second stop portion engages with the lower end wall of the guide groove to limit its movement, preventing the reversing component from extending out of the guide groove. This also prevents the reversing component from deviating from its preset movement trajectory when driven by the first driving component, and prevents the reversing component from failing to rotate the connecting frame to a preset angle, further improving the operational reliability of the pipe grinding machine.

[0018] Preferably, the pipe grinding machine further includes: a locking assembly; along the second direction of the mounting platform, one side wall of the guide groove is provided with two receiving holes, the two receiving holes are spaced apart along the first direction of the mounting platform, the reversing member is slidably disposed between the two receiving holes, along the first direction of the mounting platform, one end and the other end of the reversing member are provided with locking portions, each receiving hole is provided with the locking assembly, the locking assembly includes an elastic member and a locking member, the locking member is movably disposed in the receiving hole and adapted to abut against the other side wall of the guide groove, the elastic member is elastically deformable disposed between the bottom wall of the receiving hole and the locking member, a locking gap is defined between the locking member and the end wall of the guide groove, the locking portion is adapted to extend into the locking gap and lock into the locking member, the locking portion is used to drive the locking member to extend into the receiving hole, and the elastic member is used to drive the locking member to extend out of the receiving hole.

[0019] By adopting the above technical solution, when the first driving member drives the reversing member to move to the left, the locking part located at the left end of the reversing member abuts against the locking part located on the left side of the reversing member. The locking part drives the locking part to extend into the receiving hole. The locking part extends into the locking gap and separates from the locking part. The elastic member drives the locking part to extend out of the receiving hole. The second driving member stops working, and the reversing member moves away from the first output gear. The locking part locks with the locking part, thereby preventing the reversing member from moving to the right when the grinding assembly is grinding the pipe, which would cause the conveying direction of the pipe to change. This can improve the working reliability of the pipe grinding machine.

[0020] Preferably, the locking member has a driving ramp at the end away from the receiving hole, the driving ramp being inclined toward the central axis of the locking member, and the locking part is adapted to move along the driving ramp to drive the locking member to extend into the receiving hole.

[0021] By adopting the above technical solution, when the locking part extends into the locking gap, the locking part abuts against the driving inclined surface, and the locking part moves along the driving inclined surface closer to the locking gap and drives the locking member to extend into the receiving hole, thereby achieving the technical effect of the locking part driving the locking member to move and extend into the locking gap.

[0022] Preferably, there are multiple rust detection components, and the multiple rust detection components are arranged sequentially along the first direction of the mounting platform.

[0023] By adopting the above technical solution, when the pipe fitting completes its first grinding, the rust detection component located on the left side of the grinding assembly detects whether there is rust on the outer peripheral wall of the pipe fitting. If rust is present, the controller controls the first drive component to drive the reversing component to rotate multiple conveyor wheels to adjust the conveying direction of the pipe fitting. The conveying mechanism conveys the pipe fitting from left to right, and the grinding assembly performs a second grinding on the pipe fitting. When the pipe fitting completes its second grinding, the rust detection component located on the right side of the grinding assembly detects whether there is rust on the outer peripheral wall of the pipe fitting. If rust is present, the controller controls the first drive component to drive the reversing component to rotate multiple conveyor wheels to adjust the conveying direction of the pipe fitting. The conveying mechanism conveys the pipe fitting from right to left, and the grinding assembly performs a third grinding on the pipe fitting. This configuration allows the pipe fitting grinder to perform multiple grinding operations to remove as much rust as possible from the outer peripheral wall of the pipe fitting, thereby improving the user experience of the pipe fitting grinder.

[0024] Preferably, the output end of the first drive member is provided with a second output gear, and the end of the power roller is provided with an input gear, wherein the second output gear and the input gear are meshed together.

[0025] By adopting the above technical solution, the first driving component drives the second output gear to rotate the input gear, and the input gear drives the power roller to rotate around the central axis of the power roller, thereby achieving the technical effect of the first driving component driving the power roller to rotate.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. By using a rust detection device to detect the presence of rust on the outer wall of the pipe fitting, when rust is found, the controller controls the first drive unit to rotate multiple conveyor wheels to the right. These wheels then transport the pipe fitting from left to right, and the grinding assembly re-grinds the outer wall of the fitting. Compared to existing technologies, operators no longer need to refeed the pipe fitting into the grinding machine, thus improving processing efficiency. Furthermore, it avoids operator oversights that could result in incompletely rusted fittings being mixed with cleaned fittings, thereby improving product quality. 2. When the grinding assembly finishes grinding the outer peripheral wall of the pipe fitting, and there is rust on the outer peripheral wall of the pipe fitting, the controller controls the second drive component to drive the reversing component to move the drive rack close to the first output gear according to the detection signal of the rust detection component. The drive rack meshes with the first output gear. The first drive component drives the reversing component through the first output gear to drive multiple connecting frames to rotate. The connecting frames drive the corresponding conveying parts to rotate, thereby achieving the technical effect of driving the reversing component to move through the first drive component. 3. When the first driving member drives the reversing member to move to the left, the locking part located at the left end of the reversing member abuts against the locking part located on the left side of the reversing member. The locking part drives the locking part to extend into the receiving hole. The locking part extends into the locking gap and separates from the locking part. The elastic member drives the locking part to extend out of the receiving hole. The second driving member stops working, and the reversing member moves away from the first output gear. The locking part locks with the locking part, thereby preventing the reversing member from moving to the right when the grinding assembly is grinding the pipe, which would cause the conveying direction of the pipe to change. This improves the working reliability of the pipe grinding machine. Attached Figure Description

[0029] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0030] This application discloses a pipe grinding machine 100.

[0031] Reference Figure 1 and Figure 2 The pipe grinding machine 100 according to the embodiments of this application includes: a mounting platform 1, a conveying mechanism 2, a rust detection component 3, a controller, and a grinding assembly 4. The grinding assembly 4 is disposed on the mounting platform 1 and is used to grind the outer peripheral wall of the pipe fitting. Specifically, the grinding assembly 4 includes a grinding wheel and a motor. The motor is mounted on the mounting platform 1, and the grinding wheel is connected and cooperates 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 adapted to abut against the outer peripheral wall of the pipe fitting, and the grinding wheel is used to grind the rust on the outer peripheral wall of the pipe fitting.

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

[0033] The conveying mechanism 2 includes a power roller 21, multiple conveying wheels 22, and a first drive member 23. The power roller 21 and the multiple conveying wheels 22 are pivotally mounted on the mounting platform 1. The multiple conveying wheels 22 are arranged sequentially along a first direction of the mounting platform 1. The multiple conveying wheels 22 and the power roller 21 are spaced apart along a second direction of the mounting platform 1, and are arranged opposite to each other. A pipe is movably clamped between the multiple conveying wheels 22 and the power roller 21. Specifically, the outer peripheral wall of the pipe abuts against both the power roller 21 and the multiple conveying wheels 22. The pipe is adapted to move left or right along the first direction of the mounting platform 1, and is also adapted to rotate around its central axis. The first direction of the mounting platform 1 can be defined as... Figure 1 The left and right directions in the middle, the second direction of mounting platform 1 can refer to Figure 1 The front and back directions in the middle.

[0034] In some specific embodiments, multiple conveyor wheels 22 may also be arranged sequentially at intervals along the first direction of the mounting platform 1.

[0035] Each conveyor wheel 22 has a preset angle between its central axis and the central axis of the power roller 21, and multiple conveyor wheels 22 are tilted toward the same side. That is, multiple conveyor wheels 22 can tilt toward the left side at the same time, or multiple conveyor wheels 22 can tilt toward the right side at the same time.

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

[0037] Furthermore, the first driving member 23 is connected to the power roller 21 and is adapted to be connected to multiple conveying wheels 22. The first driving member 23 is used to drive the power roller 21 to rotate the pipe around the central axis of the pipe, and the pipe is adapted to drive multiple conveying wheels 22 to rotate around the central axis of the conveying wheels 22. The conveying wheels 22 are 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 wheels 22 to rotate around the central axis of the conveying wheels 22. The conveying wheels 22 apply a driving force to the pipe. The direction of the driving force has an angle with the central axis of the pipe. The driving force can be divided into a component force in the axial direction of the pipe and a component force in the radial direction of the pipe. The component force in 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 wheels 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 conveyor wheel 22 and the central axis of the power roller 21.

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

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

[0041] Furthermore, the rust detection element 3 is mounted on the mounting platform 1 and is used to detect rust on the outer peripheral wall of the pipe fitting. Specifically, along the height direction of the mounting platform 1, the rust detection element 3 is located above the pipe fitting and to the left of the grinding assembly 4. The pipe fitting enters the pipe fitting grinding machine 100 from the right side of the mounting platform 1, and the conveying mechanism 2 conveys the pipe fitting from right to left. Both the rust detection element 3 and the first driving element 23 are communicatively connected to the controller. The controller is used to control the first driving element 23 to drive multiple conveying wheels 22 to rotate according to the detection signal of the rust detection element 3. The height direction of the mounting platform 1 can be defined as follows: Figure 1 The up and down directions in the middle.

[0042] When the first drive unit 23 does not drive the multiple conveyor wheels 22 to rotate around the pivot axis between the conveyor wheels 22 and the mounting platform 1, the multiple conveyor wheels 22 are all tilted to the left. After the grinding assembly 4 finishes grinding the outer peripheral wall of the pipe, the rust detection unit 3 detects whether there is rust on the outer peripheral wall of the pipe. When there is no rust on the outer peripheral wall of the pipe, the controller controls the first drive unit 23 not to drive the multiple conveyor wheels 22 to rotate according to the detection signal of the rust detection unit 3. That is to say, the multiple conveyor wheels 22 convey the pipe from right to left, and the grinding assembly 4 only grinds the pipe once.

[0043] When there is rust on the outer wall of the pipe fitting, the controller controls the first drive unit 23 to drive multiple conveyor wheels 22 to rotate to the right according to the detection signal of the rust detection unit 3. The multiple conveyor wheels 22 convey the pipe fitting from left to right, and the grinding component 4 grinds the outer wall of the pipe fitting again to remove the rust.

[0044] Furthermore, after the pipe fittings have undergone secondary grinding, the first drive unit 23 drives multiple conveyor wheels 22 to rotate to the left.

[0045] In some specific embodiments, the rust detection element 3 can be a CCD (Charge-Coupled Device camera), but this application is not limited to this, and the rust detection element 3 can also be an electromagnetic sensor, etc.

[0046] It should be noted that the electromagnetic sensor applies an alternating magnetic field to the pipe, which induces a current inside the pipe. This induced current generates a magnetic field, and the electromagnetic sensor identifies whether there is rust in the pipe by detecting the magnetic field generated by the induced current. When there is rust in the pipe, the rust will change the magnetic permeability or conductivity of the pipe, thereby changing the magnitude of the induced current.

[0047] Therefore, by using the rust detection component 3 to detect whether there is rust on the outer wall of the pipe fitting, when rust is found, the controller controls the first drive component 23 to drive multiple conveyor wheels 22 to rotate to the right. The multiple conveyor wheels 22 convey the pipe fitting from left to right, and the grinding component 4 re-grinds the outer wall of the pipe fitting. Compared with the prior art, the operator does not need to refeed the pipe fitting into the pipe fitting grinding machine 100, which can improve the processing efficiency of the pipe fitting. It can also avoid the operator missing the inspection, resulting in pipe fittings with incomplete rust removal being mixed into the cleaned pipe fittings, thereby improving the product quality of the pipe fittings.

[0048] Reference Figures 2-4 In some embodiments of this application, the conveying mechanism 2 further includes a reversing member 24, which is slidably disposed on the mounting platform 1 and adapted to be connected to the first driving member 23 for transmission. The conveying wheel 22 includes a conveying part 221 and a connecting frame 222. The connecting frame 222 is pivotally connected to the mounting platform 1, and the conveying part 221 is pivotally connected to the connecting frame 222. The conveying part 221 is used to convey pipe fittings. Specifically, there is a preset angle between the central axis of the conveying part 221 and the central axis of the power roller 21. The power roller 21 drives the pipe fittings to drive the conveying part 221 to rotate around the pivot axis between the conveying part 221 and the connecting frame 222. The conveying part 221 conveys pipe fittings along the first direction of the mounting platform 1.

[0049] The reversing member 24 is connected to the connecting frame 222 in a transmission manner. 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 to the left, so as to drive multiple connecting frames 222 to rotate to the left 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 to the right, so as to drive multiple connecting frames 222 to rotate to the right 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 to the left or right, and the conveying part 221 conveys the pipe to the left or right, thereby achieving the technical effect of adjusting the conveying direction of the pipe through the conveying part 221.

[0050] Reference Figures 2-4 In some embodiments of this application, the connecting frame 222 is provided with a waist-shaped hole 2221, which is a through hole. The reversing member 24 is provided with a plurality of driving protrusions 241 arranged sequentially 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 a one-to-one correspondence and are connected in transmission. The driving protrusions 241 extend into the corresponding waist-shaped holes 2221 and are connected in transmission with the corresponding waist-shaped holes 2221.

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

[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. The driving protrusions 241 abut against the right side wall of the corresponding waist-shaped hole 2221, and drive the connecting frame 222 to rotate to the right through the waist-shaped hole 2221, thereby achieving the technical effect of driving the connecting frame 222 to rotate through the reversing member 24.

[0053] In some specific embodiments, the plurality of drive protrusions 241 may be spaced apart along the first direction of the mounting platform 1.

[0054] Reference Figures 2-4 In some embodiments of this application, the output end of the first driving member 23 is provided with a first output gear 231, and the reversing member 24 is provided with a driving rack 242. 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 adapted to mesh with each other. The first output gear 231 is located above the driving rack 242.

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

[0056] Specifically, when the grinding component 4 finishes grinding the outer peripheral wall of the pipe and there is rust on the outer peripheral wall of the pipe, the controller controls the second driving component 11 to drive the reversing component 24 to drive the driving rack 242 to move closer to the first output gear 231 according to the detection signal of the rust detection component 3. The driving rack 242 meshes with the first output gear 231, and the first driving component 23 drives the reversing component 24 to drive multiple connecting frames 222 to rotate through the first output gear 231. The connecting frames 222 drive the corresponding conveying part 221 to rotate, thereby achieving the technical effect of driving the reversing component 24 to move through the first driving component 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. Under the action of gravity, the reversing member 24 drives the driving rack 242 to move away from the first output gear 231. The driving rack 242 and the first output gear 231 separate. 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 avoiding the conveying part 221 from being unable to convey the pipe to the grinding assembly 4.

[0058] When the grinding component 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 drive component 11 to stop working based on the detection signal of the rust detection component 3.

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

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

[0061] Reference Figure 2 and Figure 4 In some embodiments of this application, the mounting platform 1 is provided with a guide groove 12, which is a through groove. The guide groove 12 extends along a first direction of the mounting platform 1. The reversing member 24 is slidably disposed in the guide groove 12 and guides and cooperates with the guide groove 12. Through the guide 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 this application, the outer peripheral wall of the reversing member 24 is provided with a first stop portion 243 and a second stop portion 244. The first stop portion 243 and the second stop portion 244 are spaced apart along the height direction of the mounting platform 1. The reversing 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 adapted to limit the engagement with one end wall of the guide groove 12, and the second stop portion 244 is adapted to limit the engagement 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 the engagement 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 failing 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 is limited and engaged with the lower end wall of the guide groove 12, thereby preventing the reversing member 24 from extending out of the guide groove 12, preventing the reversing member 24 from deviating from the preset motion trajectory when the first driving member 23 drives the reversing member 24 to move, and preventing the reversing member 24 from failing to drive the connecting frame 222 to rotate to the 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 arranged around the outer peripheral wall of the reversing member 24.

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

[0067] Each receiving hole 121 is provided with a locking assembly 5, which includes an elastic member 51 and a locking member 52. The locking member 52 is movably disposed in the receiving hole 121 and adapted to abut against the other side wall of the guide groove 12. Specifically, the receiving hole 121 is located on the rear end wall of the guide groove 12, and the end of the locking member 52 away from the receiving hole 121 is adapted to abut against the front end wall of the guide groove 12. The elastic member 51 is elastically deformable and disposed between the bottom wall of the receiving hole 121 and the locking member 52. A locking gap 521 is defined between the locking member 52 and the end wall of the guide groove 12. Specifically, the locking member 52 in the receiving hole 121 near the left side wall of the guide groove 12 defines a locking gap 521 between the left side wall of the guide groove 12 and the right side wall of the guide groove 12.

[0068] The locking part 245 is adapted to extend into the locking gap 521 and lock into the locking member 52. The locking part 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 part 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. The locking part 245 drives the locking member 52 to extend into the receiving hole 121. The locking part 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 receiving hole 121. The second driving member 11 stops working, and the reversing member 24 moves away from the first output gear 231. The locking member 52 locks with the locking part 245, thereby preventing the reversing member 24 from moving to the right when the grinding assembly 4 is grinding the pipe, which would cause the conveying direction of the pipe to change. This can improve the working reliability of the pipe grinding machine 100.

[0070] When the first driving member 23 drives the reversing member 24 to move to the right, the locking part 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. The locking part 245 drives the locking member 52 to extend into the receiving hole 121, and the locking part 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 the preset position, the locking part 245 located at the right end of the reversing member 24 abuts against the locking member 52 located on the right side of the reversing member 24. The locking part 245 located at the right end of the reversing member 24 drives the locking member 52 to extend into the receiving hole 121. The locking part 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 receiving hole 121. The second driving member 11 stops working, and the reversing member 24 moves away from the first output gear 231. The locking member 52 and the locking part 245 lock into each other.

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

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

[0074] Reference Figure 6 and Figure 7 In some embodiments of this application, the end of the locking member 52 away from the receiving hole 121 is provided with a driving ramp 522. Along the second direction of the mounting platform 1, the driving ramp 522 is located at the front end of the locking member 52. The driving ramp 522 is inclined toward the central axis of the locking member 52. The locking part 245 is adapted to move along the driving ramp 522 to drive the locking member 52 to extend into the receiving hole 121.

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

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

[0077] Reference Figure 1 and Figure 2In some embodiments of this application, there are multiple rust detection elements 3, which are arranged sequentially along the first direction of the mounting platform 1. In some specific embodiments, there are two rust detection elements 3, one of which 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 first ground, the pipe is conveyed from right to left. When the first grinding of the pipe is completed, the rust detection element 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 element 23 to drive the reversing element 24 to drive 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 a second grinding on the pipe.

[0078] When the pipe fitting completes 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 peripheral wall of the pipe fitting. When there is rust on the outer peripheral wall of the pipe fitting, the controller controls the first drive component 23 to drive the reversing component 24 to drive multiple conveying wheels 22 to rotate to adjust the conveying direction of the pipe fitting. The conveying mechanism 2 conveys the pipe fitting from right to left. The grinding component 4 grinds the pipe fitting three times. With this setting, the pipe fitting grinding machine 100 can grind the pipe fitting multiple times to remove as much rust as possible from the outer peripheral wall of the pipe fitting, thereby improving the user experience of the pipe fitting grinding machine 100.

[0079] Reference Figure 1 In some embodiments of this application, the output end of the first drive member 23 is provided with a second output gear 232, and the left end of the power roller 21 is provided with an input gear 211 along the first direction of the mounting platform 1. The second output gear 232 and the input gear 211 are meshed together.

[0080] The second output gear 232 and the input gear 211 are meshed together. The first driving member 23 drives the second output gear 232 to drive the input gear 211 to rotate. 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 can be constructed as bevel gears.

[0082] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
