Description

Technical Field

[0001] This application relates to the field of pipe fitting processing equipment, and in particular to a pipe fitting grinding equipment. Background Technology

[0002] In related technologies, when splicing two pipe fittings at an angle, a preset bevel angle needs to be ground at both ends of the pipe fittings to allow the ends to align and be fixedly connected by welding. Traditional pipe fitting grinding equipment has two support pieces for the pipe fittings, and there is an angle between the pipe fittings and the grinding belt. The grinding belt is used to simultaneously grind the preset bevel angle at the ends of both pipe fittings. The operator adjusts the angle between the support pieces and the grinding belt by hand. This adjustment makes it difficult to ensure that the angle between the two support pieces and the grinding belt is consistent, resulting in inaccurate alignment of the ends of the two pipe fittings and thus reducing the splicing quality between the two pipe fittings. Summary of the Invention

[0003] In order to ensure the consistency of the included angle between the two placement parts and the grinding belt as much as possible, and to improve the splicing quality between the two pipe fittings, this application provides a pipe fitting grinding device.

[0004] The pipe grinding equipment provided in this application adopts the following technical solution: A pipe grinding device includes: a mounting table, on the top wall of which two placement components are pivotally mounted and spaced apart along a first direction of the mounting table, and the pipe is placed on the placement components.

[0005] A driving mechanism includes a first pivot member, a second pivot member, and a first driving member. The first driving member is disposed on the mounting platform. The first pivot member and the second pivot member are pivotally mounted on the mounting platform at a distance from each other along a first direction. The first pivot member is connected and cooperates with one of the placement members, and the second pivot member is connected and cooperates with another placement member. The first driving member is adapted to be drively connected to the first pivot member and / or the second pivot member. The first driving member is used to drive the pivot member to drive the corresponding placement member to rotate around the central axis of the pivot member.

[0006] A grinding belt is pivotally mounted on the mounting platform and adapted to be opposite the pipe fitting, the end wall of the pipe fitting being adapted to have an angle with the grinding belt, the grinding belt grinding the end wall of the pipe fitting when driven.

[0007] By adopting the above technical solution, the first driving component is connected to both the first pivot component and the second pivot component. The first driving component simultaneously drives the placement component connected to the first pivot component and the placement component connected to the second pivot component to rotate closer to or further away from the grinding belt. Compared with the prior art, the angle between the two placement components and the grinding belt can be kept consistent, which can avoid inconsistent angles of the grinding belt at the ends of the two pipes, and can avoid the difficulty in accurately aligning the ends of the two pipes, thereby improving the splicing quality between the two pipes.

[0008] Preferably, the first driving member has an output shaft, on which a first transmission member and a second transmission member are sleeved, and a third pivot member is pivotally sleeved. The first transmission member and the second transmission member are both connected and cooperate with the output shaft. The first transmission member and the first pivot member are arranged opposite to each other, and the second transmission member and the third pivot member are arranged opposite to each other. The third pivot member is drively connected to the second pivot member. A driving slider is slidably arranged on the end wall of the transmission member near the corresponding pivot member. The driving slider is adapted to extend into or move out of the corresponding pivot member. The first driving member drives the first transmission member and the second transmission member to rotate around the central axis of the output shaft. The transmission member drives the corresponding pivot member to rotate around the center of the output shaft through the driving slider.

[0009] By adopting the above technical solution, when the first driving member drives the first pivot member and the second pivot member to rotate simultaneously, the driving slider located in the first transmission member extends into the first pivot member and is connected and cooperates with the first pivot member, and the driving slider located in the second transmission member extends into the third pivot member and is connected and cooperates with the third pivot member. The first driving member drives both the first transmission member and the second transmission member to rotate around the central axis of the output shaft. The first transmission member drives the first transmission member to drive the placement member connected and cooperates with the first pivot member to rotate. The first transmission member drives the second transmission member to drive the third pivot member to rotate. The third pivot member drives the second pivot member to rotate, so that the second pivot member drives the placement member connected and cooperates with the second pivot member to rotate. Thus, the technical effect of the first driving member driving the two placement members to rotate simultaneously can be achieved.

[0010] Preferably, the first transmission member has a receiving hole near the end wall of the first pivot member and the second transmission member has a receiving hole near the end wall of the third pivot member. The first pivot member has a driving hole near the end wall of the first transmission member and the third pivot member has a driving hole near the end wall of the second transmission member. The bottom wall of the receiving hole is provided with a second driving member. The driving slider is slidably disposed in the receiving hole. The driving slider is adapted to be opposite to the driving hole. The second driving member is drivenly connected to the driving slider. The second driving member is used to drive the driving slider to extend into or move out of the driving hole.

[0011] By adopting the above technical solution, when the first transmission member drives the first pivot member to rotate and / or the second transmission member drives the third pivot member to rotate, the second driving member drives the driving slider to move close to the driving hole. The driving slider extends into the driving hole and abuts against the inner peripheral wall of the driving hole. When the first driving member drives the first transmission member and the second transmission member to rotate, the first transmission member drives the first pivot member to rotate through the driving slider located on the first transmission member, and the second transmission member drives the third pivot member to rotate through the driving slider located on the second transmission member. Thus, the technical effect of the first transmission member driving the first pivot member to rotate and the technical effect of the second transmission member driving the third pivot member to rotate can be achieved.

[0012] Preferably, the outer peripheral wall of the drive slider is provided with a limiting part, which is adapted to limit the engagement with the end wall of the drive hole near the receiving hole.

[0013] By adopting the above technical solution, the limiting part and the end wall of the open end of the drive hole can prevent the drive slider from being completely inserted into the drive hole. This can prevent the first transmission component from being unable to drive the first pivot component to rotate through the drive slider, and the second transmission component from being unable to drive the third pivot component to rotate through the drive slider, thereby improving the working reliability of the pipe grinding equipment.

[0014] Preferably, the end wall of the drive slider away from the drive hole is provided with an elastic element that can be elastically deformed. The end of the elastic element away from the drive slider passes through the second drive member and is connected to the bottom wall of the receiving hole. The elastic element is used to drive the drive slider to move closer to the drive hole.

[0015] By adopting the above technical solution, the elastic element can assist the second driving element in driving the driving slider to move closer to the driving hole. This can prevent the force applied by the second driving element to the driving slider towards the driving hole from decreasing when the current flowing through the second driving element decreases. This can prevent the second driving element from failing to drive the driving slider to extend into the driving hole, thereby improving the working reliability of the pipe grinding equipment.

[0016] Preferably, the inner peripheral wall of the receiving hole is provided with a guide groove, the guide groove extends along the height direction of the mounting platform, and the outer peripheral wall of the driving slider is provided with a first guide portion, the first guide portion and the guide groove are guided and engaged.

[0017] By adopting the above technical solution, the first guide part and the guide groove are guided and cooperated to prevent the drive slider from deviating from the preset motion trajectory and to prevent the drive slider from failing to extend into the drive hole, thereby improving the working reliability of the pipe grinding equipment.

[0018] Preferably, there are multiple receiving holes, driving holes, driving sliders, and second driving components. The multiple receiving holes, driving holes, driving sliders, and second driving components are all spaced apart along the circumferential direction of the mounting platform, and the multiple receiving holes, driving holes, driving sliders, and second driving components are arranged in a one-to-one correspondence.

[0019] By adopting the above technical solution, multiple second driving components drive multiple driving sliders to extend into corresponding driving holes. The first transmission component drives the first pivot component to rotate through multiple driving sliders, and the second transmission component drives the third pivot component to rotate through multiple driving sliders. When one of the multiple driving sliders is damaged, the transmission component drives the corresponding pivot component to rotate through the driving slider that can work normally, thereby improving the driving reliability between the transmission component and the corresponding pivot component.

[0020] Preferably, the outer peripheral wall ring of the third pivot member is provided with output teeth, and the outer peripheral wall ring of the second pivot member is provided with input teeth, and the output teeth and the input teeth are meshed together.

[0021] By adopting the above technical solution, the first driving member drives the second transmission member to rotate the third pivot member, the third pivot member drives the second pivot member to rotate through the output teeth and input teeth, and the second pivot member drives the placement member connected and cooperating with the second pivot member to rotate, thereby achieving the technical effect of the first driving member driving the placement member connected and cooperating with the second pivot member to rotate.

[0022] Preferably, the mounting platform is provided with two guide rails, which are spaced apart along a first direction of the mounting platform, and the two guide rails are corresponding to the two placement components one by one. The guide rails are arc-shaped and extend along the circumference of the mounting platform. The placement component is provided with a second guide portion near the end wall of the mounting platform, and the second guide portion guides and cooperates with the guide rails.

[0023] By adopting the above technical solution, the second guide part and the guide rail can guide and cooperate to prevent the placement parts from deviating from the preset motion trajectory, thereby preventing the angle between the two placement parts and the grinding belt from being unequal, and thus improving the working reliability of the pipe grinding equipment.

[0024] Preferably, the mounting platform has two locking grooves, which are spaced apart along a first direction of the mounting platform, and each locking groove corresponds to one of the two placement members. The locking grooves are arc-shaped and extend along the circumference of the mounting platform. Each placement member has a locking hole opposite to the locking groove. The locking member passes through the locking groove and the locking hole in sequence and has a fastener at its end. The fastener is used to lock or unlock the placement member and the mounting platform.

[0025] By adopting the above technical solution, when the placement component rotates to the preset angle, the placement component and the mounting platform are locked by tightening the fasteners, and the placement component and the mounting platform are unlocked by loosening the fasteners. This can prevent the placement component from rotating when the grinding belt is grinding the pipe fitting, thus preventing the grinding belt from grinding the preset angle at the end of the pipe fitting. This can improve the working reliability of the pipe fitting grinding equipment.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. A first driving member is connected to both a first pivot member and a second pivot member. The first driving member simultaneously drives the placement member connected to the first pivot member and the placement member connected to the second pivot member to rotate closer to or further away from the grinding belt. Compared with the prior art, the angle between the two placement members and the grinding belt can be kept consistent, which can avoid inconsistent angles of the grinding belt at the ends of the two pipes, and can avoid the difficulty in accurately aligning the ends of the two pipes, thereby improving the splicing quality between the two pipes. 2. By using the limiting part and the end wall of the open end of the drive hole to stop, the drive slider can be prevented from being completely inserted into the drive hole, which can prevent the first transmission component from being unable to drive the first pivot component to rotate through the drive slider, and the second transmission component from being unable to drive the third pivot component to rotate through the drive slider, thereby improving the working reliability of the pipe grinding equipment. 3. When the placement component rotates to the preset angle, the placement component and the mounting platform are locked by tightening the fasteners, and the placement component and the mounting platform are unlocked by loosening the fasteners. This can prevent the placement component from rotating when the grinding belt is grinding the pipe fitting, which would prevent the grinding belt from grinding the preset angle at the end of the pipe fitting. This can improve the working reliability of the pipe fitting grinding equipment. Attached Figure Description

[0029] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

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

[0031] Reference Figures 1-3 The pipe grinding equipment 100 according to the embodiments of this application includes: a mounting platform 1, a drive mechanism 2, and a grinding belt 3. Two placement members 11 are pivotally mounted on the top wall of the mounting platform 1, spaced apart along a first direction of the mounting platform 1. The pipe is placed on the placement members 11. Along the height direction of the mounting platform 1, the top wall of the mounting platform 1 refers to the upper end wall of the mounting platform 1. The height direction of the mounting platform 1 is... Figure 1 The vertical direction of the mounting platform 1 is the first direction. Figure 1 The left and right directions in the middle.

[0032] Furthermore, the top wall of the placement component 11 is provided with a placement groove 115, the pipe is placed in the placement groove 115 and is limited to fit the placement groove 115, and the placement groove 115 penetrates the placement component 11 along the length direction of the placement component 11.

[0033] The drive mechanism 2 includes a first pivot member 21, a second pivot member 22, and a first drive member 23. The first drive member 23 is disposed on the mounting platform 1. The first pivot member 21 and the second pivot member 22 are pivotally mounted on the mounting platform 1 at a distance from each other along a first direction. The first pivot member 21 is located to the right of the second pivot member 22. The first pivot member 21 is connected and engaged with one placement member 11, and the second pivot member 22 is connected and engaged with the other placement member 11. Specifically, the first pivot member 21 is connected and engaged with the right placement member 11 of the two placement members 11, and the second pivot member 22 is connected and engaged with the left placement member 11 of the two placement members 11.

[0034] Furthermore, the first driving member 23 is adapted to be connected to the first pivot member 21 and / or the second pivot member 22 in a transmission connection. The first driving member 23 is used to drive the pivot member to drive the corresponding placement member 11 to rotate around the central axis of the pivot member. The grinding belt 3 is pivotally mounted on the mounting platform 1 and is adapted to be opposite to the pipe. The end wall of the pipe is adapted to have an angle with the grinding belt 3. When the grinding belt 3 is driven, it grinds the end wall of the pipe.

[0035] Specifically, when the angle between the two placement pieces 11 and the grinding belt 3 is adjusted simultaneously, the first driving member 23 is connected to both the first pivot piece 21 and the second pivot piece 22. The first driving member 23 drives the first pivot piece 21 to rotate the corresponding placement piece 11 around the central axis of the first pivot piece 21, and the first driving member 23 simultaneously drives the second pivot piece 22 to rotate the corresponding placement piece 11 around the central axis of the second pivot piece 22, so that the angle between the two placement pieces 11 and the grinding belt 3 remains consistent.

[0036] In some specific embodiments, the placement members 11 are respectively a first placement member 11 and a second placement member 11. The first placement member 11 is located to the right of the second placement member 11. The end wall of the tube placed on the first placement member 11 away from the second placement member 11 has an angle with the grinding belt 3. The end wall of the tube placed on the second placement member 11 away from the first placement member 11 has an angle with the grinding belt 3. The first pivot member 21 is connected to the end of the first placement member 11 near the grinding belt 3. The second pivot member 22 is connected to the end of the second placement member 11 near the grinding belt 3. When the first driving member 23 drives the first placement member 11 to rotate counterclockwise, the first driving member 23 drives the second placement member 11 to rotate clockwise, so that the angle between the tube placed on the first placement member 11 and the grinding belt 3 is consistent with the angle between the tube placed on the second placement member 11 and the grinding belt 3. In some other specific embodiments, when the first driving member 23 drives the first placement member 11 to rotate clockwise, the first driving member 23 drives the second placement member 11 to rotate counterclockwise.

[0037] Furthermore, when only the angle between a single placement piece 11 and the grinding belt 3 needs to be adjusted, the first driving member 23 is connected to the first pivot member 21 or the second pivot member 22. The first driving member 23 drives the first pivot member 21 to rotate the corresponding placement piece 11 around the central axis of the first pivot member 21, or the first driving member 23 drives the second pivot member 22 to rotate the corresponding placement piece 11 around the central axis of the second pivot member 22. This allows for adjustment of the angle between a single placement piece 11 and the grinding belt 3, enabling the processing of bevels of different sizes on the end wall of the pipe fitting, thereby improving the user experience of the pipe fitting grinding equipment 100.

[0038] Furthermore, the pipe grinding equipment 100 also includes a controller. The mounting platform 1 is equipped with two angle detection elements and an indicator light. The two angle detection elements are spaced apart along the first direction of the mounting platform 1. The two angle detection elements are set one-to-one with the two placement elements 11. The angle detection elements are used to detect the angle between the placement element 11 and the grinding belt 3. Both angle detection elements and the indicator light are connected to the controller. When the angle between the two placement elements 11 and the grinding belt 3 is equal, the controller controls the indicator light to provide an indication based on the detection signals from the two angle detection elements. After adjusting the angle between one placement element 11 and the grinding belt 3 individually, the operator can determine whether the angle between the two placement elements 11 and the grinding belt 3 is consistent by observing the indicator light. This can prevent inconsistent angles of the grinding belt 3 at the pipe end, and can prevent the two pipes from not being able to be precisely connected.

[0039] In some specific embodiments, the bevel angle of the pipe end can be 45°, but this application is not limited to this, and the bevel angle of the pipe end can be 60°, etc.

[0040] Therefore, through the transmission connection between the first driving member 23 and both the first pivot member 21 and the second pivot member 22, the first driving member 23 simultaneously drives the placement member 11 connected to the first pivot member 21 and the placement member 11 connected to the second pivot member 22 to rotate closer to or further away from the grinding belt 3. Compared with the prior art, the angle between the two placement members 11 and the grinding belt 3 can be kept consistent, which can avoid the inconsistent angle of the grinding belt 3 at the ends of the two pipes, and can avoid the difficulty in accurately aligning the ends of the two pipes, thereby improving the splicing quality between the two pipes.

[0041] Reference Figure 2 and Figure 3In some embodiments of this application, the first driving member 23 has an output shaft 231. A first transmission member 232 and a second transmission member 233 are sleeved on the outer peripheral wall of the output shaft 231, and a third pivot member 234 is pivotally sleeved thereon. Both the first transmission member 232 and the second transmission member 233 are connected and cooperate with the output shaft 231, and the third pivot member 234 is pivotally connected to the output shaft 231. Along the height direction of the mounting platform 1, the first pivot member 21 is located above the first transmission member 232, and the third pivot member 234 is located above the second transmission member 233. The first transmission member 232 and the first pivot member 21 are arranged opposite to each other, and the second transmission member 233 and the third pivot member 234 are arranged opposite to each other. The third pivot member 234 is drively connected to the second pivot member 22.

[0042] Furthermore, a drive slider 235 is slidably disposed on the end wall of the transmission member near the corresponding pivot member. Specifically, the drive slider 235 is slidably disposed on the end wall of the first transmission member 232 near the end wall of the first pivot member 21, and the drive slider 235 is slidably disposed on the end wall of the second transmission member 233 near the end wall of the third pivot member 234. The drive slider 235 is adapted to extend into or move out of the corresponding pivot member. The first drive member 23 drives the first transmission member 232 and the second transmission member 233 to rotate around the central axis of the output shaft 231. The transmission member drives the corresponding pivot member to rotate around the center of the output shaft 231 through the drive slider 235. Specifically, the first transmission member 232 drives the first pivot member 21 to rotate around the center of the output shaft 231 through the drive slider 235 slidably disposed on the first transmission member 232, and the second transmission member 233 drives the third pivot member 234 to rotate around the center of the output shaft 231 through the drive slider 235 slidably disposed on the second transmission member 233.

[0043] Specifically, when the first driving member 23 drives the first pivot member 21 and the second pivot member 22 to rotate simultaneously, the driving slider 235 located in the first transmission member 232 extends into the first pivot member 21 and is connected and engaged with the first pivot member 21. The driving slider 235 located in the second transmission member 233 extends into the third pivot member 234 and is connected and engaged with the third pivot member 234. The first driving member 233 drives both the first transmission member 232 and the second transmission member 233 to rotate around the central axis of the output shaft 231. The first transmission member 232 drives the first transmission member 232 to drive the placement member 11 connected and engaged with the first pivot member 21 to rotate. The first transmission member 232 drives the second transmission member 233 to drive the third pivot member 234 to rotate. The third pivot member 234 drives the second pivot member 22 to rotate, so that the second pivot member 22 drives the placement member 11 connected and engaged with the second pivot member 22 to rotate. Thus, the technical effect of the first driving member 23 driving the two placement members 11 to rotate simultaneously can be achieved.

[0044] When the first driving member 23 does not need to drive the first pivot member 21 and / or the third pivot member 234 to rotate, the driving slider 235 located in the first transmission member 232 moves out of the first pivot member 21 and separates from the first pivot member 21, so the first transmission member 232 cannot drive the first pivot member 21 to rotate, and the driving slider 235 located in the second transmission member 233 moves out of the third pivot member 234 and separates from the third pivot member 234, so the second transmission member 233 cannot drive the third pivot member 234 to rotate.

[0045] In some specific embodiments, the first driving element 23 can be a motor or the like.

[0046] Reference Figure 2 and Figure 3 In some embodiments of this application, the end wall of the first transmission member 232 near the first pivot member 21 and the end wall of the second transmission member 233 near the third pivot member 234 are provided with receiving holes 2321. The end wall of the first pivot member 21 near the first transmission member 232 and the end wall of the third pivot member 234 near the second transmission member 233 are provided with driving holes 211. Specifically, along the height direction of the mounting platform 1, the upper end wall of the first transmission member 232 and the upper end wall of the second transmission member 233 are provided with receiving holes 2321, and the receiving holes 2321 are constructed as blind holes. The lower end wall of the first pivot member 21 and the lower end wall of the third pivot member 234 are provided with driving holes 211, and the driving holes 211 are constructed as blind holes.

[0047] The bottom wall of the receiving hole 2321 is provided with a second driving member 236, and the driving slider 235 is slidably disposed in the receiving hole 2321. The driving slider 235 is adapted to be opposite to the driving hole 211. The second driving member 236 is connected to the driving slider 235 in a transmission manner. The second driving member 236 is used to drive the driving slider 235 to extend into or move out of the driving hole 211.

[0048] Specifically, when the first transmission member 232 drives the first pivot member 21 to rotate and / or the second transmission member 233 drives the third pivot member 234 to rotate, the second driving member 236 drives the driving slider 235 to move closer to the driving hole 211. The driving slider 235 extends into the driving hole 211 and abuts against the inner peripheral wall of the driving hole 211. When the first driving member 23 drives the first transmission member 232 and the second transmission member 233 to rotate, the first transmission member 232 drives the first pivot member 21 to rotate through the driving slider 235 located in the first transmission member 232, and the second transmission member 233 drives the third pivot member 234 to rotate through the driving slider 235 located in the second transmission member 233. Thus, the technical effect of the first transmission member 232 driving the first pivot member 21 to rotate and the technical effect of the second transmission member 233 driving the third pivot member 234 to rotate can be achieved.

[0049] When the first transmission member 232 does not need to drive the first pivot member 21 to rotate and / or the second transmission member 233 does not need to drive the third pivot member 234 to rotate, the second driving member 236 drives the driving slider 235 to move away from the driving hole 211, and the driving slider 235 moves out of the driving hole 211. When the first driving member 23 drives the first transmission member 232 and the second transmission member 233 to rotate, the first transmission member 232 rotates relative to the first pivot member 21, and the second transmission member 233 rotates relative to the third pivot member 234.

[0050] Furthermore, when the receiving hole 2321 and the driving hole 211 are not opposite, the second driving member 236 first drives the driving slider 235 to move closer to the driving hole 211. The driving slider 235 abuts against the end wall of the pivot member near the transmission member. Then, the first driving member 23 drives the first transmission member 232 and the second transmission member 233 to rotate. The first transmission member 232 drives the driving slider 235 located in the first transmission member 232 to rotate relative to the first pivot member 21. The second transmission member 233 drives the driving slider 235 located in the second transmission member 233 to rotate relative to the third pivot member 234. When the receiving hole 2321 and the driving hole 211 are opposite, the second driving member 236 drives the driving slider 235 to extend into the driving hole 211.

[0051] It should be noted that only a portion of the drive slider 235 extends into the drive hole 211. That is, the upper end of the drive slider 235 extends into the drive hole 211, while the lower end of the drive slider 235 is located in the receiving hole 2321.

[0052] In some specific embodiments, the second driving element 236 can be an electromagnet, and the driving slider 235 is made of magnetic material.

[0053] Reference Figure 2 and Figure 3 In some embodiments of this application, the outer peripheral wall of the drive slider 235 is provided with a limiting part 2351. The limiting part 2351 is adapted to limit the engagement with the end wall of the drive hole 211 near the receiving hole 2321. That is, the limiting part 2351 is adapted to stop against the end wall of the open end of the drive hole 211. It should be noted that, along the height direction of the mounting platform 1, the end wall of the open end of the drive hole 211 is the lower end wall of the first pivot member 21 and the lower end wall of the second pivot member 22.

[0054] Specifically, when the second driving member 236 drives the driving slider 235 to move close to the driving hole 211, the limiting part 2351 and the end wall of the open end of the driving hole 211 stop the driving slider 235 from being completely inserted into the driving hole 211. This prevents the first transmission member 232 from being unable to drive the first pivot member 21 to rotate through the driving slider 235, and the second transmission member 233 from being unable to drive the third pivot member 234 to rotate through the driving slider 235, thereby improving the working reliability of the pipe grinding equipment 100.

[0055] Reference Figure 2 and Figure 3 In some embodiments of this application, the end wall of the drive slider 235 away from the drive hole 211 is provided with an elastic member 2352 that can be elastically deformed. One end of the elastic member 2352 away from the drive slider 235 passes through the second drive member 236 and is connected and engaged with the bottom wall of the receiving hole 2321. That is, along the height direction of the mounting platform 1, the lower end of the drive slider 235 and the bottom wall of the receiving hole 2321 are connected by the elastic member 2352. The elastic member 2352 is used to drive the drive slider 235 to move closer to the drive hole 211.

[0056] Specifically, the elastic element 2352 can assist the second driving element 236 in driving the driving slider 235 to move closer to the driving hole 211. This can prevent the force applied by the second driving element 236 to the driving slider 235 towards the driving hole 211 from decreasing when the current flowing through the second driving element 236 decreases. This can prevent the second driving element 236 from failing to drive the driving slider 235 to extend into the driving hole 211, thereby improving the working reliability of the pipe grinding equipment 100.

[0057] Furthermore, the second driving member 236 can drive the driving slider 235 to move away from the driving hole 211. When the transmission member drives the pivot member to rotate, the elastic member 2352 drives the driving slider 235 to move closer to the driving hole 211. When the transmission member does not need to drive the pivot member to rotate, the second driving member 236 drives the driving slider 235 to move away from the driving hole 211. This setting can simplify the working complexity of the second driving member 236, thereby reducing the difficulty of using the pipe grinding equipment 100 and improving the user experience of the pipe grinding equipment 100.

[0058] Reference Figure 2 and Figure 3 In some embodiments of this application, the inner peripheral wall of the receiving hole 2321 is provided with a guide groove 2322, the guide groove 2322 extends along the height direction of the mounting platform 1, and the outer peripheral wall of the drive slider 235 is provided with a first guide portion 2353, the first guide portion 2353 and the guide groove 2322 are guided and cooperated.

[0059] By guiding and cooperating with the first guide part 2353 and the guide groove 2322, the drive slider 235 can be prevented from deviating from the preset motion trajectory, and the drive slider 235 can be prevented from failing to extend into the drive hole 211, thereby improving the working reliability of the pipe grinding equipment 100.

[0060] Furthermore, there are multiple guide grooves 2322 and first guide parts 2353. The multiple guide grooves 2322 and first guide parts 2353 are arranged sequentially at intervals along the circumferential direction of the receiving hole 2321, and the multiple guide grooves 2322 and first guide parts 2353 are arranged in a one-to-one correspondence. By setting multiple guide grooves 2322 and multiple first guide parts 2353, the guiding reliability of the guide grooves 2322 for the drive slider 235 can be improved.

[0061] Reference Figure 2 and Figure 3 In some embodiments of this application, there are multiple receiving holes 2321, driving holes 211, driving sliders 235 and second driving members 236. The multiple receiving holes 2321, multiple driving holes 211, multiple driving sliders 235 and multiple second driving members 236 are all spaced apart along the circumferential direction of the mounting platform 1, and the multiple receiving holes 2321, multiple driving holes 211, multiple driving sliders 235 and multiple second driving members 236 are arranged in a one-to-one correspondence.

[0062] When the first transmission member 232 drives the first pivot member 21 to rotate and / or the second transmission member 233 drives the third pivot member 234 to rotate, multiple second driving members 236 drive multiple driving sliders 235 to extend into the corresponding driving holes 211. The first transmission member 232 drives the first pivot member 21 to rotate through the multiple driving sliders 235, and the second transmission member 233 drives the third pivot member 234 to rotate through the multiple driving sliders 235. When one of the multiple driving sliders 235 is damaged, the transmission member drives the corresponding pivot member to rotate through the driving slider 235 that is working normally, thereby improving the driving reliability between the transmission member and the corresponding pivot member.

[0063] Reference Figure 2 and Figure 3 In some embodiments of this application, the outer peripheral wall ring of the third pivot member 234 is provided with an output tooth 2341, and the outer peripheral wall ring of the second pivot member 22 is provided with an input tooth 221. The output tooth 2341 and the input tooth 221 are meshed together. The first driving member 23 drives the second transmission member 233 to rotate the third pivot member 234. The third pivot member 234 drives the second pivot member 22 to rotate through the output tooth 2341 and the input tooth 221. The second pivot member 22 drives the placement member 11 connected and cooperating with the second pivot member 22 to rotate, thereby achieving the technical effect that the first driving member 23 drives the placement member 11 connected and cooperating with the second pivot member 22 to rotate.

[0064] Reference Figure 1 , Figure 4 and Figure 5 In some embodiments of this application, the mounting platform 1 is provided with two guide rails 12, which are spaced apart along a first direction of the mounting platform 1, and the two guide rails 12 are corresponding to two placement members 11. The guide rails 12 are arc-shaped and extend along the circumferential direction of the mounting platform 1. The placement member 11 is provided with a second guide portion 111 near the end wall of the mounting platform 1, and the second guide portion 111 guides and cooperates with the guide rails 12.

[0065] By using the second guide part 111 and the guide rail 12 for guidance and cooperation, the placement part 11 can be prevented from deviating from the preset movement trajectory, thereby preventing the angle between the two placement parts 11 and the grinding belt 3 from being unequal, and thus improving the working reliability of the pipe grinding equipment 100.

[0066] Reference Figure 1 , Figure 4 and Figure 5 In some embodiments of this application, the mounting platform 1 is provided with two locking grooves 13, which are spaced apart along a first direction of the mounting platform 1, and the two locking grooves 13 are corresponding to two placement members 11. The locking grooves 13 are arc-shaped and extend along the circumferential direction of the mounting platform 1. The locking grooves 13 penetrate the mounting platform 1 along the height direction of the mounting platform 1. The placement member 11 is provided with a locking hole 112 opposite to the locking groove 13, and the locking hole 112 is a through hole. The locking member 113 passes through the locking groove 13 and the locking hole 112 in sequence and is provided with a fastener 114 at its end. The fastener 114 is used to lock or unlock the placement member 11 and the mounting platform 1.

[0067] One end of the locking member 113 passes through the locking groove 13 and the locking hole 112 in sequence. The fastener 114 is provided at the end of the locking member 113 that passes through the locking hole 112 and the locking groove 13. When the placement member 11 rotates to the preset angle, the placement member 11 and the mounting table 1 are locked by tightening the fastener 114, and the placement member 11 and the mounting table 1 are unlocked by loosening the fastener 114. This can prevent the placement member 11 from rotating when the grinding belt 3 is grinding the pipe fitting, which would prevent the grinding belt 3 from grinding the preset angle at the end of the pipe fitting. This can improve the working reliability of the pipe fitting grinding equipment 100.

[0068] It should be noted that the end of the locking member 113 that passes through the locking hole 112 and the locking groove 13 is provided with external threads. In some specific embodiments, the fastener 114 can be a nut, and the fastener 114 and the locking member 113 are threadedly connected.

[0069] 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.
