[0029] The following is combined with Figure 1-Figure 5 This application is described in further detail.

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

[0031] Reference Figure 1-Figure 3 According to the embodiment of the present application, the pipe grinding device 100 comprises: a mounting platform 1, a driving mechanism 2 and a grinding belt 3. The top wall of the mounting platform 1 is pivotally mounted with two placement pieces 11 spaced apart along a first direction of the mounting platform 1. The pipe is placed on the placement pieces 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 first direction of the mounting platform 1 is Figure 1 The left and right direction in .

[0032] Furthermore, a placement groove 115 is provided on the top wall of the placement piece 11 , and the pipe is placed in the placement groove 115 and limitedly cooperates with the placement groove 115 , and the placement groove 115 penetrates the placement piece 11 along the length direction of the placement piece 11 .

[0033] The driving mechanism 2 includes a first pivot member 21, a second pivot member 22 and a first driving member 23. The first driving member 23 is arranged on the mounting table 1. The first pivot member 21 and the second pivot member 22 are pivotally mounted on the mounting table 1 at intervals along a first direction of the mounting table 1. The first pivot member 21 is located on the right side of the second pivot member 22. The first pivot member 21 is connected and cooperated with one placing member 11, and the second pivot member 22 is connected and cooperated with the other placing member 11. Specifically, the first pivot member 21 is connected and cooperated with the placing member 11 located on the right side of the two placing members 11, and the second pivot member 22 is connected and cooperated with the placing member 11 located on the left side of the two placing members 11.

[0034] Furthermore, the first driving member 23 is suitable for being transmission-connected with the first pivot member 21 and / or the second pivot member 22. 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 table 1 and is suitable to be opposite to the pipe fitting. The end wall of the pipe fitting is suitable to have an angle with the grinding belt 3. The end wall of the pipe fitting is polished when the grinding belt 3 is driven.

[0035] Specifically, when the angle between the two placement members 11 and the polishing belt 3 is adjusted at the same time, the first driving member 23 is transmission-connected with the first pivot member 21 and the second pivot member 22. The first driving member 23 drives the first pivot member 21 to drive the corresponding placement member 11 to rotate around the central axis of the first pivot member 21, and the first driving member 23 simultaneously drives the second pivot member 22 to drive the corresponding placement member 11 to rotate around the central axis of the second pivot member 22, so that the angle between the two placement members 11 and the polishing belt 3 remains consistent.

[0036] In some specific embodiments, the placement piece 11 is respectively a first placement piece 11 and a second placement piece 11, the first placement piece 11 is located on the right side of the second placement piece 11, there is an angle between the end wall of the tube placed on the first placement piece 11 away from the second placement piece 11 and the polishing belt 3, there is an angle between the end wall of the tube placed on the second placement piece 11 away from the first placement piece 11 and the polishing belt 3, the first pivot member 21 is connected and cooperated with the end of the first placement piece 11 close to the polishing belt 3, the second pivot member 22 is connected and cooperated with the end of the second placement piece 11 close to the polishing belt 3, when the first driving member 23 drives the first placement piece 11 to rotate counterclockwise, the first driving member 23 drives the second placement piece 11 to rotate clockwise, so that the angle between the tube placed on the first placement piece 11 and the polishing belt 3 is consistent with the angle between the tube placed on the second placement piece 11 and the polishing belt 3. In some other specific embodiments, when the first driving member 23 drives the first placing member 11 to rotate clockwise, the first driving member 23 drives the second placing member 11 to rotate counterclockwise.

[0037] Furthermore, when only the angle between a placement member 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, and the first driving member 23 drives the first pivot member 21 to drive the corresponding placement member 11 to rotate around the central axis of the first pivot member 21, or the first driving member 23 drives the second pivot member 22 to drive the corresponding placement member 11 to rotate around the central axis of the second pivot member 22, thereby achieving the adjustment of the angle between a single placement member 11 and the grinding belt 3, and bevels of different angles can be processed on the end wall of the pipe, thereby improving the user experience of the pipe grinding equipment 100.

[0038] In addition, the pipe grinding equipment 100 also includes a controller. The mounting table 1 is provided with two angle detection members and a prompt light. The two angle detection members are arranged at intervals along the first direction of the mounting table 1. The two angle detection members are arranged in a one-to-one correspondence with the two placement members 11. The angle detection member is used to detect the angle between the placement member 11 and the grinding belt 3. The two angle detection members and the prompt light are both communicatively connected to the controller. When the angles of the angles between the two placement members 11 and the grinding belt 3 are equal, the controller controls the prompt light to give a prompt according to the detection signals of the two angle detection members. After adjusting the angle of the angle between one placement member 11 and the grinding belt 3 separately, the operator can determine whether the angles of the angles between the two placement members 11 and the grinding belt 3 are consistent by observing the prompt light, thereby avoiding the inconsistency of the bevel angles polished by the grinding belt 3 at the end of the pipe and avoiding the inability to accurately dock the two pipes.

[0039] In some specific embodiments, the bevel angle of the end of the pipe fitting may be 45°, but the present application is not limited thereto, and the bevel angle of the end of the pipe fitting may be 60° or the like.

[0040] Thus, the first driving member 23 is connected to the first pivot member 21 and the second pivot member 22 through transmission, and 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 away from the grinding belt 3. Compared with the prior art, the angles between the two placement members 11 and the grinding belt 3 can be kept consistent, which can avoid the grinding belt 3 from grinding at the ends of the two pipes at an inconsistent angle, and can avoid the difficulty of the ends of the two pipes to be accurately butted, thereby improving the splicing quality between the two pipes.

[0041] Reference Figure 2 and Figure 3In some embodiments of the present application, the first driving member 23 has an output shaft 231, the outer peripheral wall of the output shaft 231 is sleeved with a first transmission member 232 and a second transmission member 233, and a third pivot member 234 is pivotally sleeved, the first transmission member 232 and the second transmission member 233 are both connected and matched 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, the third pivot member 234 is located above the second transmission member 233, the first transmission member 232 is arranged opposite to the first pivot member 21, the second transmission member 233 and the third pivot member 234 are arranged opposite to each other, and the third pivot member 234 is transmission-connected to the second pivot member 22.

[0042] In addition, a driving slider 235 is slidably provided on the end wall of the transmission member near the corresponding pivot member. Specifically, the first transmission member 232 is slidably provided with a driving slider 235 near the end wall of the first pivot member 21, and the second transmission member 233 is slidably provided with a driving slider 235 near the end wall of the third pivot member 234. The driving slider 235 is suitable for extending into or moving out of the corresponding pivot member. The first driving 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 driving 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 driving slider 235 slidably provided 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 driving slider 235 slidably provided 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 at the first transmission member 232 extends into the first pivot member 21 and is connected and cooperated with the first pivot member 21, and the driving slider 235 located at the second transmission member 233 extends into the third pivot member 234 and is connected and cooperated with the third pivot member 234. The first driving 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 first transmission member 232 drives the first transmission member 232 to drive the placement member 11 connected and cooperated 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 cooperated with the second pivot member 22 to rotate, thereby achieving the technical effect that the first driving member 23 simultaneously drives the two placement members 11 to rotate.

[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 at the first transmission member 232 moves out of the first pivot member 21 and separates from the first pivot member 21, and the first transmission member 232 cannot drive the first pivot member 21 to rotate, and the driving slider 235 located at the second transmission member 233 moves out of the third pivot member 234 and separates from the third pivot member 234, and the second transmission member 233 cannot drive the third pivot member 234 to rotate.

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

[0046] Reference Figure 2 and Figure 3 In some embodiments of the present application, the end wall of the first transmission member 232 close to the first pivot member 21 and the end wall of the second transmission member 233 close to the third pivot member 234 are both provided with a receiving hole 2321, and the end wall of the first pivot member 21 close to the first transmission member 232 and the end wall of the third pivot member 234 close to the second transmission member 233 are both provided with a driving hole 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 both provided with a receiving hole 2321, and the receiving hole 2321 is constructed as a blind hole, and the lower end wall of the first pivot member 21 and the lower end wall of the third pivot member 234 are both provided with a driving hole 211, and the driving hole 211 is constructed as a blind hole.

[0047] A second driving member 236 is provided on the bottom wall of the accommodating hole 2321. The driving slider 235 is slidably arranged in the accommodating hole 2321. The driving slider 235 is suitable to be opposite to the driving hole 211. The second driving member 236 is transmission-connected with the driving slider 235. 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 close to the driving hole 211, and the driving slider 235 extends into the driving hole 211 and stops against the inner circumferential 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 on 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 on the second transmission member 233, thereby achieving 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.

[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] Further, when the accommodating hole 2321 and the driving hole 211 are not opposite to each other, the second driving member 236 first drives the driving slider 235 to move close to the driving hole 211, and the driving slider 235 stops against the end wall of the pivot member close to the transmission member, and 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 at the first transmission member 232 to rotate relative to the first pivot member 21, and the second transmission member 233 drives the driving slider 235 located at the second transmission member 233 to rotate relative to the third pivot member 234, and when the accommodating hole 2321 and the driving hole 211 are opposite to each other, 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 partial area of ​​the driving slider 235 extends into the driving hole 211 , that is, the upper end of the driving slider 235 extends into the driving hole 211 , and the lower end of the driving slider 235 is located in the accommodating hole 2321 .

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

[0053] Reference Figure 2 and Figure 3 In some embodiments of the present application, a limiting portion 2351 is provided on the outer peripheral wall of the driving slider 235, and the limiting portion 2351 is suitable for limiting cooperation with the end wall of the driving hole 211 close to the accommodating hole 2321, that is, the limiting portion 2351 is suitable for abutting against the end wall of the open end of the driving 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 driving 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 portion 2351 and the end wall of the open end of the driving hole 211 are used to stop the driving slider 235, thereby preventing the driving slider 235 from fully extending into the driving hole 211. This can prevent the first transmission member 232 from being unable to drive the first pivot member 21 to rotate through the driving slider 235, and prevent 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 the present application, an elastic member 2352 that can be elastically deformed is provided on the end wall of the driving slider 235 away from the driving hole 211, and one end of the elastic member 2352 away from the driving slider 235 passes through the second driving member 236 to be connected and cooperated with the bottom wall of the accommodating hole 2321. That is to say, along the height direction of the mounting platform 1, an elastic member 2352 is connected between the lower end of the driving slider 235 and the bottom wall of the accommodating hole 2321, and the elastic member 2352 is used to drive the driving slider 235 to move close to the driving hole 211.

[0056] Specifically, the elastic member 2352 can assist the second driving member 236 in driving the driving slider 235 to move closer to the driving hole 211, thereby avoiding that when the current flowing through the second driving member 236 decreases, the force applied by the second driving member 236 to the driving slider 235 toward the driving hole 211 is reduced accordingly, and the second driving member 236 can be prevented from being unable 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 only 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 close 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. Such a setting can simplify the working complexity of the second driving member 236, thereby reducing the difficulty of using the pipe grinding equipment 100, and further improving the user experience of the pipe grinding equipment 100.

[0058] Reference Figure 2 and Figure 3 In some embodiments of the present application, the inner wall of the accommodating hole 2321 is provided with a guide groove 2322, and the guide groove 2322 is extended along the height direction of the mounting platform 1. The outer wall of the driving slider 235 is provided with a first guide portion 2353, and the first guide portion 2353 and the guide groove 2322 are guided and matched.

[0059] Through the guiding cooperation between the first guide portion 2353 and the guide groove 2322, the driving slider 235 can be prevented from deviating from the preset motion trajectory and the driving slider 235 can be prevented from being unable to extend into the driving hole 211, thereby improving the working reliability of the pipe grinding equipment 100.

[0060] Furthermore, there are a plurality of guide grooves 2322 and a first guide portion 2353, and the plurality of guide grooves 2322 and the first guide portion 2353 are arranged in sequence and spaced apart along the circumferential direction of the accommodating hole 2321, and the plurality of guide grooves 2322 and the first guide portion 2353 are arranged in one-to-one correspondence. By setting a plurality of guide grooves 2322 and a plurality of first guide portions 2353, the guiding reliability of the guide groove 2322 on the driving slider 235 can be improved.

[0061] Reference Figure 2 and Figure 3 In some embodiments of the present application, there are multiple accommodating holes 2321, multiple driving holes 211, multiple driving sliders 235 and multiple second driving members 236, and the multiple accommodating holes 2321, multiple driving holes 211, multiple driving sliders 235 and multiple second driving members 236 are all arranged at intervals along the circumferential direction of the mounting table 1, and the multiple accommodating 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, the multiple second driving members 236 drive the 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 can work 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 the present 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, and the output tooth 2341 is meshedly connected with the input tooth 221. The first driving member 23 drives the second transmission member 233 to drive the third pivot member 234 to rotate, and the third pivot member 234 drives the second pivot member 22 to rotate through the output tooth 2341 and the input tooth 221, and the second pivot member 22 drives the placement member 11 connected and matched with the second pivot member 22 to rotate, so that the technical effect of the first driving member 23 driving the placement member 11 connected and matched with the second pivot member 22 to rotate can be achieved.

[0064] Reference Figure 1 , Figure 4 and Figure 5 In some embodiments of the present application, the mounting table 1 is provided with two guide rails 12, the two guide rails 12 are spaced apart along the first direction of the mounting table 1, and the two guide rails 12 are arranged one-to-one with the two placement pieces 11, the shape of the guide rails 12 is arc-shaped, and the guide rails 12 are extended along the circumferential direction of the mounting table 1, and the placement piece 11 is provided with a second guide portion 111 near the end wall of the mounting table 1, and the second guide portion 111 is guided and matched with the guide rails 12.

[0065] The cooperation between the second guide portion 111 and the guide track 12 can prevent the placement member 11 from deviating from the preset motion trajectory, thereby preventing the angles between the two placement members 11 and the grinding belt 3 from being unequal, thereby improving the working reliability of the pipe grinding equipment 100.

[0066] Reference Figure 1 , Figure 4 and Figure 5 In some embodiments of the present application, the mounting table 1 is provided with two locking grooves 13, the two locking grooves 13 are spaced apart along the first direction of the mounting table 1, and the two locking grooves 13 are arranged one by one with the two placement pieces 11, the shape of the locking grooves 13 is configured as an arc, and the locking grooves 13 are extended along the circumferential direction of the mounting table 1, and the locking grooves 13 penetrate the mounting table 1 along the height direction of the mounting table 1, the placement piece 11 is provided with a locking hole 112 opposite to the locking groove 13, and the locking hole 112 is configured as a through hole, the locking piece 113 passes through the locking groove 13 and the locking hole 112 in sequence, and a fastener 114 is provided at the end, and the fastener 114 is used to lock or unlock the placement piece 11 and the mounting table 1.

[0067] One end of the locking piece 113 passes through the locking groove 13 and the locking hole 112 in sequence, and the fastener 114 is arranged at the end of the locking piece 113 passing through the locking hole 112 and the locking groove 13. When the placement piece 11 is rotated to a preset angle, the placement piece 11 and the mounting table 1 are locked by tightening the fastener 114, and the placement piece 11 and the mounting table 1 are unlocked by loosening the fastener 114, thereby preventing the placement piece 11 from rotating when the grinding belt 3 is grinding the pipe fitting, causing the grinding belt 3 to be unable to grind the preset angle of the bevel at the end of the pipe fitting, thereby improving the working reliability of the pipe fitting grinding equipment 100.

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