[0036] It should be noted that: during the cutting process of the steel pipe body 102, the steel pipe body 102 is placed between the first C-shaped clamping plate 202 and the second C-shaped clamping plate 203 of the two sets of clamping components, and the second C-shaped clamping plate 203 is driven to move toward the first C-shaped clamping plate 202 through the lifting component. During the movement, the steel pipe body 102 is limited and clamped between the first C-shaped clamping plate 202 and the second C-shaped clamping plate 203;

[0037] The cutting assembly includes a U-shaped frame 501 fixed on the mounting seat 4, a cutting knife 502 is rotatably connected to the U-shaped frame 501, and a driving motor 503 for driving the cutting knife 502 is installed on the U-shaped frame 501;

[0038] It should be noted here that: after the steel pipe body 102 is clamped and fixed, the mounting seat 4 is driven to move toward the strip frame 3 through the lifting assembly. During the downward movement of the mounting seat 4, the cutting knife 502 on the U-shaped frame 501 is driven to move downward synchronously. During the downward movement of the cutting knife 502, the cutting knife 502 is driven to rotate by the driving motor 503. Through the downward movement and rotation of the cutting knife 502, the steel pipe body 102 is cut. During the cutting process of the steel pipe body 102, the steel pipe body 102 is driven to rotate by the rotating assembly. Through the rotation of the steel pipe body 102, the steel pipe body 102 is cut into two groups, and the cutting process of the steel pipe body 102 is completed;

[0039] It is worth noting here that the lifting assembly is a conventional technical means in the prior art, and is summarized as a conventional technical component in this application, and no further elaboration is given here. Common lifting assemblies include cylinder lifting and screw lifting. Referring to the drawings in the specification of this application, this application mainly adopts a screw lifting assembly;

[0040] Also includes:

[0041] A rotating assembly is provided between the two groups of clamping assemblies for rotating the clamped steel pipe body 102. The first C-shaped clamping plate 202 and the second C-shaped clamping plate 203 are provided with auxiliary assemblies for assisting the rotation of the steel pipe body 102.

[0042] A separation component symmetrically arranged on both sides of the U-shaped frame 501 for separating the two groups of steel pipe bodies 102 after cutting and a processing component for chamfering and deburring the outer side of the cut end of the steel pipe body 102 after separation;

[0043] The separation component includes a rectangular frame 801 fixed to one side of the U-shaped frame 501, a slide 802 is arranged below the rectangular frame 801, a sliding component for assisting the slide 802 to slide is arranged between the slide 802 and the rectangular frame 801, a pressing plate 803 is arranged below the slide 802, a first telescopic component for assisting telescopic movement is arranged between the pressing plate 803 and the slide 802, an arc groove 804 for abutting against the outer side of the steel pipe body 102 is opened on the pressing plate 803, and an elastic extrusion component for elastically extruding the pressing plate 803 is arranged between the rectangular frame 801 and the pressing plate 803;

[0044] It should be noted here that: during the cutting process of the steel pipe body 102, when the steel pipe body 102 is completely cut into two groups, the two groups of steel pipe bodies 102 after cutting are pushed away from each other through the separation component. During the separation process, the rotating component and the processing component are cooperated to grind, deburr and flanging the outer side of the end of the steel pipe body 102 after cutting, so as to facilitate the subsequent processing operations of the steel pipe body 102 after cutting.

[0045] Preferably, the first telescopic assembly includes a plurality of first sleeves 901 fixed below the slide seat 802, the first sleeves 901 are slidably connected with a first slide bar 902, one end of the first slide bar 902 is fixed to the pressing plate 803, the outer side of the first sleeve 901 is sleeved with a first spring 903, and the two ends of the first spring 903 are respectively connected to the slide seat 802 and the pressing plate 803;

[0046] It should be noted here that: in the process of cutting the steel pipe body 102 by descending the U-shaped frame 501 and the cutting knife 502, the arc groove 804 on the pressure plate 803 is abutted against the outer side of the steel pipe body 102 through the connection between the rectangular frame 801, the slide seat 802 and the first telescopic component. As the steel pipe body 102 acts on the pressure plate 803 and the rectangular frame 801 continues to descend, the rectangular frame 801 moves toward the pressure plate 803. During the movement, the elastic force of the first spring 903 on the first telescopic component pushes the pressure plate 803 to abut against the outer side of the steel pipe body 102 with a greater force, so that when the pressure plate 803 is subsequently pushed, the friction between the pressure plate 803 and the outer side of the steel pipe body 102 drives the cut steel pipe body 102 to be separated.

[0047] Preferably, the elastic extrusion component includes a mounting groove 1001 provided on the pressure plate 803, a transmission plate 1002 is slidably connected to the mounting groove 1001, an elastic component for elastically connecting the transmission plate 1002 is arranged inside the mounting groove 1001, a slope 1003 is provided on one side of the transmission plate 1002, and a push plate 1004 for driving against the slope 1003 is fixed at the lower end of the rectangular frame 801; the elastic component includes a plurality of groups of second sleeves 1401 fixed inside the mounting groove 1001, a second slide bar 1402 is slidably connected to the second sleeve 1401, one end of the second slide bar 1402 is fixed to the transmission plate 1002, a second spring 1403 is sleeved on the outer side of the second sleeve 1401, and the two ends of the second spring 1403 are respectively arranged against the mounting groove 1001 and the transmission plate 1002;

[0048] It should be noted here that: as the rectangular frame 801 moves toward the pressure plate 803, the push plate 1004 below the rectangular frame 801 is abutted against the inclined surface 1003 on the transmission plate 1002, pushing the transmission plate 1002 to move toward the inside of the installation groove 1001. During the movement, the second slide bar 1402 is pushed to slide on the second sleeve 1401 and the second spring 1403 on the elastic component is deformed by force to generate elastic force on the pressure plate 803. At this time, the steel pipe body 102 is not completely cut into two groups. At this time, the elastic force of the second spring 1403 cannot push the pressure plate 803 to move. When the steel pipe body 102 is completely cut into two groups, the pushing force of the second spring 1403 on the pressure plate 803 and the abutment between the pressure plate 803 and the cut steel pipe body 102 push the two groups of cut steel pipe bodies 102 away from each other.

[0049] Preferably, the processing assembly includes a fixing frame 1201 fixed to one side of the U-shaped frame 501, a mounting platform 1202 is arranged below the fixing frame 1201, a second telescopic assembly for assisting the telescopic connection is arranged between the mounting platform 1202 and the fixing frame 1201, an operating plate 1203 is fixed to the lower end of the mounting platform 1202, and the operating plate 1203 is located between the cutting knife 502 and the pressing plate 803, and an oblique grinding surface 1204 for abutting against the outer side of the end portion of the steel pipe body 102 after cutting is opened at the lower end of the operating plate 1203;

[0050] It should be noted here that: in the process of separating the two groups of steel pipe bodies 102 after cutting, the second telescopic component is used to push the oblique grinding surface 1204 at the lower end of the operating plate 1203 below the mounting table 1202 against the outer side of the ends of the two groups of steel pipe bodies 102 after cutting. At this time, the two groups of steel pipe bodies 102 after cutting and separation are driven to rotate through the rotating component. Because the oblique grinding surfaces 1204 on the two groups of processing components are against the outer side of the ends of the steel pipe bodies 102, the outer side of the ends of the steel pipe bodies 102 after cutting are ground, deburred and flanging processed through the rotation of the steel pipe bodies 102.

[0051] Preferably, the second telescopic assembly includes a third sleeve 1301 fixed to the lower end of the fixing frame 1201, a third slide bar 1302 is slidably connected to the third sleeve 1301, one end of the third slide bar 1302 is fixed to the mounting platform 1202, a third spring 1303 is sleeved on the outer side of the third sleeve 1301, and both ends of the third spring 1303 are respectively connected to the mounting platform 1202 and the fixing frame 1201;

[0052] It should be noted here that: during the downward movement of the U-shaped frame 501, the lower end of the operating plate 1203 is driven to abut against the outer side of the steel pipe body 102 through the connection between the fixed frame 1201, the second telescopic assembly and the mounting platform 1202. Through the abutment and limiting effect of the steel pipe body 102 on the operating plate 1203 and the continued downward movement of the U-shaped frame 501, the fixed frame 1201 is moved toward the mounting platform 1202. During the movement, the third sliding rod 1302 is pushed to slide on the third sleeve 1301 and the third spring 1303 is deformed to generate elastic force. Through the elastic force of the third spring 1303, the operating plate 1203 on the mounting platform 1202 is elastically pushed, so that during the separation process of the two groups of steel pipe bodies 102 after cutting, the oblique grinding surface 1204 on the operating plate 1203 is pushed against the outer side of the end of the steel pipe body 102.

[0053] Preferably, the sliding assembly includes a support seat 1101 fixed below the rectangular frame 801, and a plurality of groups of T-shaped slide bars 1102 are slidably connected to the support seat 1101, one end of each group of T-shaped slide bars 1102 is fixed to one side of the slide seat 802, and a fourth spring 1103 is sleeved on the outer side of the T-shaped slide bar 1102;

[0054] It should be noted here that: during the movement of the steel pipe body 102 and the pressure plate 803, the slide 802 is driven to move through the first telescopic component. During the movement of the slide 802, the sliding action of multiple groups of T-shaped slide bars 1102 on the support seat 1101 is used to guide the movement of the slide 802 after the force is applied. During the movement of the slide 802, the fourth spring 1103 is deformed under force to generate elastic force. The elastic force of the fourth spring 1103 facilitates the reset movement of the slide 802 after auxiliary movement.

[0055] Preferably, a limit baffle 1104 is fixed below the rectangular frame 801 to limit the position of the sliding seat 802 after sliding;

[0056] It should be noted here that: during the movement of the steel pipe body 102, the pressure plate 803 and the slide 802, the limit baffle 1104 is abutted against one side of the slide 802 to limit the movement of the steel pipe body 102, the pressure plate 803 and the slide 802. By limiting the movement of the steel pipe body 102, it is convenient to more accurately process the end of the steel pipe body 102.

[0057] Preferably, the rotating assembly includes a slot 601 opened on two groups of support frames 201, a driving shaft 602 is arranged on the slot 601, a plurality of rubber wheels 603 for abutting against the lower side of the steel pipe body 102 after placement are fixed on the driving shaft 602, two groups of auxiliary frames 604 are fixed on the upper end of the operating table 101, the driving shaft 602 is rotatably connected between the two groups of auxiliary frames 604, and a mounting motor 605 for driving the driving shaft 602 is installed on the auxiliary frame 604;

[0058] It should be noted here that: when the steel tube body 102 limit card is set between the first C-shaped clamping plate 202 and the second C-shaped clamping plate 203, the steel tube body 102 is against the multiple groups of rubber wheels 603. When the steel tube body 102 needs to be rotated, the motor 605 is installed to drive the drive shaft 602 and the groups of rubber wheels 603 on the drive shaft 602 to rotate. During the rotation of the rubber wheels 603, the steel tube body 102 is rotated by the friction between the rubber wheels 603 and the outer side of the steel tube body 102.

[0059] Preferably, the auxiliary component includes a plurality of ball grooves 701 provided inside the first C-shaped clamping plate 202 and the second C-shaped clamping plate 203, and the ball grooves 701 are rotatably connected with the inner part thereof to abut against the outer side of the steel pipe body 102;

[0060] It should be noted here that: when the steel tube body 102 is limited and clamped between the first C-type clamping plate 202 and the second C-type clamping plate 203, the ball 702 is abutted against the outer side of the steel tube body 102. Through the abutment between the ball 702 and the outer side of the steel tube body 102 and the rotation of the ball 702 in the ball groove 701, the steel tube body 102 can be clamped while assisting the rotation of the steel tube body 102.

[0061] In this scheme: a steel pipe cutting device for making a motor housing comprises the following steps:

[0062] When the motor housing is made by processing the steel pipe, the steel pipe body 102 is cut. During the cutting process of the steel pipe body 102, the steel pipe body 102 is placed between the first C-shaped clamping plate 202 and the second C-shaped clamping plate 203 of the two sets of clamping components. The second C-shaped clamping plate 203 is driven to move toward the first C-shaped clamping plate 202 through the lifting component. During the movement, the steel pipe body 102 is limitedly clamped between the first C-shaped clamping plate 202 and the second C-shaped clamping plate 203, and during the clamping process, the balls 702 on the first C-shaped clamping plate 202 and the second C-shaped clamping plate 203 are pressed against the outer side of the steel pipe body 102;

[0063] After the steel pipe body 102 is clamped and fixed, the mounting seat 4 is driven to move toward the strip frame 3 through the lifting assembly. During the downward movement of the mounting seat 4, the cutting knife 502 on the U-shaped frame 501 is driven to move downward synchronously. During the downward movement of the cutting knife 502, the cutting knife 502 is driven to rotate by the driving motor 503. Through the downward movement and rotation of the cutting knife 502, the steel pipe body 102 is cut. During the cutting of the steel pipe body 102, the steel pipe body 102 is driven to rotate by the rotating assembly. Through the rotation of the steel pipe body 102, the steel pipe body 102 is cut into two groups, and the cutting of the steel pipe body 102 is completed;

[0064] In the process of cutting the steel pipe body 102 by descending the U-shaped frame 501 and the cutting knife 502, the arc groove 804 on the pressing plate 803 is abutted against the outer side of the steel pipe body 102 through the connection between the rectangular frame 801, the slide seat 802 and the first telescopic component. As the steel pipe body 102 acts on the pressing plate 803 and the rectangular frame 801 continues to descend, the rectangular frame 801 moves toward the pressing plate 803. During the movement, the elastic force of the first spring 903 on the first telescopic component pushes the pressing plate 803 to abut against the outer side of the steel pipe body 102 with a greater force. As the rectangular frame 801 moves toward the pressing plate 803, the push plate 1004 below the rectangular frame 801 abuts against the inclined surface 1003 on the transmission plate 1002, pushing the transmission plate 1002 to move toward the inside of the mounting groove 1001. During the movement, the second spring 1403 on the elastic component is deformed by force to generate elastic force on the pressure plate 803. At this time, the steel tube body 102 is not completely cut into two groups. At this time, the elastic force of the second spring 1403 cannot push the pressure plate 803 to move. When the steel tube body 102 is completely cut into two groups, the pushing force of the second spring 1403 on the pressure plate 803 and the counteraction between the pressure plate 803 and the cut steel tube body 102 push the two groups of cut steel tube bodies 102 to move away from each other, so as to achieve the effect of separating the two groups of cut steel tube bodies 102. In the process of separating the two groups of cut steel tube bodies 102, the second telescopic component pushes the oblique grinding surface 1204 at the lower end of the operating plate 1203 below the mounting platform 1202 to counteract the outer sides of the ends of the two groups of cut steel tube bodies 102. Fig.12 state, at this time, the two groups of cut and separated steel pipe bodies 102 are driven to rotate through the rotating component. Because the oblique grinding surfaces 1204 on the two groups of processing components are against the outer side of the end of the steel pipe body 102, the outer side of the end of the cut steel pipe body 102 is ground, deburred and flanging processed through the rotation of the steel pipe body 102, which is convenient for subsequent processing operations of the cut steel pipe body 102.
