In order to further improve the reliability, the direction adjusting seat 303 is further provided with a fixing bolt 312 for locking and fixing the direction adjusting seat 303 on the telescopic rod of the cutting telescopic cylinder 301.

[0040] The transmission ratio of the worm wheel 314 and the worm 316 for cutting angle adjustment is calculated as follows:

[0041] ;

[0042] wherein, θ is the angle of the cutting wheel 304, L is the lead of the worm 316, r is the radius of the worm wheel 314, and Z1 and Z2 are the number of teeth of the worm 316 and the worm wheel 314, respectively.

[0043] Preferably, the direction adjusting seat 303 is fixed with a positioning ring 305 for limiting the cutting wheel 304 on the output shaft of the cutting motor 307 away from one side of the cutting motor 307, and the output shaft of the cutting motor 307 is also threadedly connected with a locking nut 308 for locking and fixing the cutting wheel 304, and the stable and reliable cutting wheel 304 can be ensured by the cooperation of the locking nut 308 and the positioning ring 305.

[0044] Through the structure limitation of the pipe cutting unit 30, the direction adjusting is convenient, reliable and accurate, and the pipe can be reliably cut by driving the cutting wheel 304 to ascend and descend through the cooperation of the cutting telescopic cylinder 301.

[0045] As shown in Figure 1 and 5 As a preferred embodiment of the present application, the pipe pushing unit 20 comprises an assembly frame one 201 adjustably and movably installed on the central bearing unit 10, the middle part of the assembly frame one 201 is fixed with an adjusting telescopic cylinder two 204, the telescopic rod end of the adjusting telescopic cylinder two 204 is fixed with an assembly plate 205, one end of the assembly plate 205 is fixed with a pushing motor 206, the output shafts on both sides of the pushing motor 206 are fixed with rotating plates 207, the ends away from the pushing motor 206 of the rotating plates 207 are hinged with pushing plates 209, the pushing plates 209 are also hinged with auxiliary plates 208, the ends away from the pushing plates 209 of the auxiliary plates 208 are hinged with the ends away from the pushing motor 206 of the assembly plate 205, the ends away from the rotating plates 207 of the two pushing plates 209 are hinged with a pushing block 210, and the lower side of the pushing block 210 is installed and fixed with elastic blocks 211.

[0046] Preferably, the assembly frame one 201 adopts an inverted U-shaped structure, the lower ends of the two branches of the assembly frame one 201 are slidably connected with an adjusting rail one 202 fixed on the central bearing unit 10, the central bearing unit 10 is also fixed with an adjusting telescopic cylinder one 203, the telescopic rod end of the adjusting telescopic cylinder one 203 is fixedly connected with the assembly frame one 201, and the assembly frame one 201 can be driven to move position relative to the pipe cutting unit 30 through the telescopic action of the adjusting telescopic cylinder one 203.

[0047] Preferably, the bottom of the elastic block 211 is an upward arc-shaped recess structure in the middle, and the bottom of the elastic block 211 is also provided with an anti-skid layer, which can limit the pipe and ensure the reliability of pushing and pressing.

[0048] Preferably, the circumferential movement of the rotating plate 207 causes the auxiliary plate 208 and the pushing plate 209 to swing and move accordingly. The end of the pushing plate 209 moves along a trajectory that is the result of the combined movement of the auxiliary plate 208 and the rotating plate 207, so that the end of the pushing plate 209 can achieve approximately horizontal linear motion, thereby pushing the pipe and forming the intermittent feeding effect of pressing the pipe → pushing the pipe → releasing the pipe → returning to the original position → and so on. The length of the rotating plate 207, the auxiliary plate 208 and the pushing plate 209 can be adjusted and / or the hinge positions between the rotating plate 207 and the pushing plate 209 and between the auxiliary plate 208 and the pushing plate 209 can be adjusted, so as to adjust the distance of the elastic block 211 pushing the pipe. For example, when the hinge position between the rotating plate 207 and the pushing plate 209 is adjusted, the force arm of the rotating plate 207 to the pushing plate 209 changes when the rotating plate 207 rotates, the horizontal displacement of the end of the pushing plate 209 changes, and the pushing distance of the pipe changes.

[0049] Through the structure of the pipe pushing unit 20, the rotating plate 207 is driven by the pushing motor 206, and the auxiliary plate 208 and the pushing plate 209 are designed to have the intermittent feeding effect of pressing the pipe → pushing the pipe → releasing the pipe → returning to the original position → and so on, and the pushing distance is adjustable. In addition, the adjustable telescopic cylinder two 204 and the adjustable telescopic cylinder one 203 are arranged to adapt to different models of pipes and different scenes, and to achieve more reliable feeding effect.

[0050] As shown in Figure 1 and 5 As a preferred embodiment of the present application, the auxiliary positioning unit 40 includes an adjustable and movable assembly frame three 402 mounted on the central bearing unit 10. The middle part of the assembly frame three 402 is fixed with an adjustable telescopic cylinder three 401, and the end of the telescopic rod of the adjustable telescopic cylinder three 401 is fixed with a positioning switch 403 for positioning the pipe. The pushing of the pipe pushing unit 20 and the positioning of the auxiliary positioning unit 40 can be adjusted, so that the pipe pushing unit 20 pushes the pipe to trigger the positioning switch 403. Specifically, when the positioning switch 403 is triggered by the pipe, the pipe cutting unit 30 cuts the pipe.

[0051] Preferably, the assembly frame three 402 adopts an inverted U-shaped structure, and the lower ends of the two branches of the assembly frame three 402 are slidably connected with the adjustable track two 404 fixed on the central bearing unit 10. The central bearing unit 10 is also fixed with an adjustable telescopic cylinder four 405, and the end of the telescopic rod of the adjustable telescopic cylinder four 405 is fixedly connected with the assembly frame three 402. Through the telescopic action of the adjustable telescopic cylinder four 405, the assembly frame three 402 can be driven to move relative to the pipe cutting unit 30.

[0052] Preferably, the center bearing unit 10 is also provided with a photoelectric sensor 50 for detecting whether the pipe cutting unit 30 has finished cutting, when the pipe cutting unit 30 finishes cutting the pipe, the adjusting telescopic cylinder three 401 of the auxiliary positioning unit 40 is shortened to avoid the positioning switch 403, at the same time, the pipe pushing unit 20 starts a new round of pipe pushing action, after the cut pipe is separated from the pipe to be cut (such as the cut pipe falling into the storage box), the adjusting telescopic cylinder three 401 of the auxiliary positioning unit 40 is extended, and the positioning switch 403 repositions the pipe; such a cycle realizes continuous positioning and cutting.

[0053] In addition, the control of each component can use the PLC controller disclosed in the prior art, and the model and circuit connection of each component are not specifically limited and can be flexibly set in actual application. The circuits, electronic components and modules involved are all prior art, and those skilled in the art can realize them without further description, and the content protected by the present application does not involve improvement of software and methods. For example, the photoelectric sensor 50 generally includes a transmitter and a receiver, which are distributed on both sides of the cutting wheel 304, when the cutting wheel 304 passes, if it completely cuts the pipe, it will temporarily block the light beam, so that it can be judged whether the cutting is completed, the photoelectric sensor 50 will send a signal to the controller, and the controller will make corresponding response according to the preset program logic, such as the adjusting telescopic cylinder three 401 of the auxiliary positioning unit 40 is shortened to avoid the positioning switch 403, at the same time, the pipe pushing unit 20 starts a new round of pipe pushing action, and the like, which will not be described here.

[0054] Through the limitation of the auxiliary positioning unit 40 and the photoelectric sensor 50, better positioning effect and the degree of mechatronics of the device can be achieved. It should be noted that even if there is a certain deviation between the pipe pushing unit 20 and the auxiliary positioning unit 40, the elastic structure of the elastic block 211 and the misaligned sliding between the elastic block 211 and the pipe can meet the actual use requirements.

[0055] As shown in Figure 1 、 2 , 5 and 6, as a preferred embodiment of the present application, the center bearing unit 10 includes two horizontal and parallel side bearing frames 101, a reinforcing plate 105 is fixedly arranged on the lower side between the two side bearing frames 101, a plurality of supporting legs 104 are also fixedly arranged on the lower side of the two side bearing frames 101, a plurality of bearing shafts 102 are uniformly and fixedly arranged on both sides between the two side bearing frames 101, and a middle arc-shaped concave bearing roller 103 is rotatably arranged on the bearing shaft 102.

[0056] Preferably, the two sides of the assembling frame two 302 of the pipe cutting unit 30 are branched to correspond to the middle fixed connection of the two side bearing frames 101, so that the cutting wheel 304 is in a suitable position and does not touch the bearing roller 103, and meets the cutting requirements. The photoelectric sensor 50 is fixed to the middle of the inner side of the side bearing frame 101. The adjusting track one 202 and the adjusting track two 404 are correspondingly fixed on the side bearing frame 101, and the adjusting telescopic cylinder one 203 and the adjusting telescopic cylinder four 405 are also correspondingly fixed on the side bearing frame 101, which meets the requirements of stably driving the assembling frame one 201 and the assembling frame three 402.

[0057] Through the limitation of the center bearing unit 10, especially the structural arrangement of the bearing roller 103, the pipe can be centrally supported, and the elastic block 211 can push the pipe, and the overall structure is reasonable and reliable.

[0058] In addition, the bearing roller 103 is made of high-strength alloy steel, the surface is plated with hard chromium, the diameter ranges from 50-150mm, and is suitable for the outer diameter of the pipe ranging from 20-200mm. The cutting wheel 304 adopts a diamond-coated blade with a thickness of 2-5mm, and the cutting linear velocity can be adjusted in the range of 10-50m / s.

[0059] A protective cover (not shown) can be installed around the cutting wheel 304 of the pipe cutting unit 30 as needed, and the protective cover is linked with the cutting motor 307 through a magnetic sensor. When the protective cover is not closed, the cutting motor 307 is automatically powered off.

[0060] The pipe cutting machine for electromechanical integrated frame production provided in the above embodiments of the application has the following working principle:

[0061] The center bearing unit 10 centrally supports the pipe through the two parallel side bearing frames 101 and the arc-shaped concave bearing roller 103 in the middle, to ensure the stability of the pipe during pushing and cutting.

[0062] The pipe pushing unit 20 drives the assembling plate 205 to move through the adjusting telescopic cylinder two 204 on the assembling frame one 201. The pushing motor 206 installed on the assembling plate 205 realizes intermittent pushing of the pipe through the linkage structure of the rotating plate 207, the auxiliary plate 208 and the pushing plate 209. The elastic block 211 is located below the pushing block 210, which is used to press and push the pipe forward, and the pushing distance is adjustable.

[0063] The auxiliary positioning unit 40 includes the assembling frame three 402, the middle of which is fixed with the adjusting telescopic cylinder three 401, the end of the telescopic rod of which is fixed with the positioning switch 403 for positioning the pipe. When the pipe is pushed to trigger the positioning switch 403, the pipe cutting unit 30 starts the cutting work of the pipe.

[0064] The pipe cutting unit 30 comprises an assembly frame two 302 fixed on the center bearing unit 10, and a cutting telescopic cylinder 301 arranged in the middle of the assembly frame two 302, and a direction adjusting seat 303 is rotatably arranged at the end of the telescopic rod of the cutting telescopic cylinder 301.

[0065] The photoelectric sensor 50 is fixed to the middle of the inner side of the side bearing frame 101, and is used for detecting whether the pipe is completely cut. When the cutting is completed, the photoelectric sensor 50 sends a signal to the controller, the controller controls the adjusting telescopic cylinder three 401 of the auxiliary positioning unit 40 to shorten, so that the positioning switch 403 avoids the pipe, and the pipe pushing unit 20 is started to carry out a new round of pipe pushing action. After the cut pipe is separated from the pipe to be cut, the adjusting telescopic cylinder three 401 is lengthened, and the positioning switch 403 repositions the pipe, so that the continuous positioning and cutting are realized.

[0066] As described above, through the cooperative work of the center bearing unit 10, the pipe pushing unit 20 and the auxiliary positioning unit 40, the accurate positioning and stable cutting of the pipe cutting position are realized, the cutting precision and efficiency are improved, and the multi-angle cutting is supported to adapt to different frame production requirements.

[0067] The technical features of the above-described embodiments can be combined arbitrarily, and in order to make the description simple, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combinations of the technical features do not exist contradictory, it should be considered that the description is within the scope of the present application.

[0068] The above-described embodiments only express several implementation manners of the present application, the description is more specific and detailed, but it should not be understood as the limitation of the patent scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
