Description

Technical Field

[0001] This utility model relates to the field of sprinkler irrigation technology, specifically to a square pipe cutting device for a sprinkler irrigation machine chassis. Background Technology

[0002] A sprinkler irrigation machine is a machine used for spraying irrigation water. It generally includes a water pump unit, pipes, sprinklers, and a traveling mechanism. The sprinkler chassis is an important component of the sprinkler irrigation machine. When cutting the square tubes of the sprinkler chassis, a pipe cutting device for the square tubes of the sprinkler chassis is required.

[0003] In existing technologies, the positioning structure of the square pipe cutting device for sprinkler machine chassis is often designed with a fixed size. The square pipe is typically positioned by passing it through a positioning groove on a rotating shaft, which cannot accommodate pipes of various sizes. When the square pipe size is smaller than the positioning groove, a gap will occur, causing displacement or vibration of the pipe during cutting, severely affecting cutting accuracy and resulting in poor cutting quality. Therefore, a new square pipe cutting device for sprinkler machine chassis is needed to solve these problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pipe cutting device for square pipes of sprinkler irrigation machine chassis to solve the problems mentioned in the background technology. This utility model has a reasonable structure, high cutting accuracy, and high cutting quality.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a pipe cutting device for square pipes on a sprinkler irrigation machine chassis, comprising:

[0006] The machine body has a rotating shaft running through its side wall, a positioning plate at the end of the rotating shaft, a through positioning groove for passing through a square tube at the ends of the rotating shaft and the positioning plate, and a laser cutting head above the positioning plate.

[0007] The positioning disk is symmetrically provided with a pair of vertical positioning rollers located on both sides of the positioning groove. The end of the positioning disk is symmetrically provided with a pair of vertical clamping drive components for driving the pair of vertical positioning rollers to move closer to or further away from each other.

[0018] The beneficial effects achieved by the present invention using the above structure are as follows:

[0019] This invention uses a vertical clamping drive assembly to move a pair of vertical positioning rollers closer together to clamp the vertically opposite side walls of a square tube. Similarly, a longitudinal clamping drive assembly moves a pair of longitudinal positioning rollers closer together to clamp the longitudinally opposite sides of the square tube.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figure 1 As shown, this utility model provides a technical solution: a pipe cutting device for square pipes on a sprinkler machine chassis, comprising:

[0028] The machine body 1 has a rotating shaft 2 running through its side wall. A positioning plate 7 is provided at the end of the rotating shaft 2. A through positioning groove 21 for passing through a square tube is provided at the ends of the rotating shaft 2 and the positioning plate 7. A laser cutting head 5 is provided above the positioning plate 7.

[0029] A pair of vertical positioning rollers 9 are symmetrically arranged on the positioning disk 7 on both sides of the positioning groove 21. A pair of vertical clamping drive components 8 are symmetrically arranged at the end of the positioning disk 7 to drive the pair of vertical positioning rollers 9 to move closer to or further away from each other. A conveying motor 91 is provided on the vertical clamping drive components 8 to drive the vertical positioning rollers 9 to rotate.

[0030] A pair of longitudinal positioning rollers 11 are symmetrically arranged on both sides of the positioning groove 21 on the positioning disk 7. A pair of longitudinal clamping drive components 10 are symmetrically arranged at the end of the positioning disk 7 to drive the pair of longitudinal positioning rollers 11 to move closer to or further away from each other. This design clamps the square tube by passing it through the positioning groove 21 and driving the pair of vertical positioning rollers 9 to move closer to each other through the vertical clamping drive components 8. The longitudinal clamping drive components 10 drive the pair of longitudinal positioning rollers 11 to move closer to each other to clamp the two opposite sides of the square tube in the longitudinal direction. This design can accommodate the positioning and clamping of square tubes of different sizes. The vertical positioning rollers 9 are rotated by the operation of the conveying motor 91 to complete the feeding of the square tube, improve the stability of clamping and conveying, avoid displacement or vibration of the square tube during the cutting process, improve cutting accuracy, and improve cutting quality.

[0031] Reference Figure 2 , Figure 3 and Figure 4 The vertical positioning roller 9 has a longitudinal length greater than the longitudinal length of the positioning groove 21, while the vertical length of the longitudinal positioning roller 11 is less than the vertical length of the positioning groove 21. This design avoids interference between the vertical positioning roller 9 and the longitudinal positioning roller 11, facilitating the clamping of the sidewall of the square tube.

[0032] Reference Figure 1 and Figure 4 A drive rotation assembly 4 for driving the rotating shaft 2 is provided on the side of the machine body 1 away from the positioning disk 7.

[0033] The drive rotation assembly 4 includes a U-shaped support plate 43 disposed on the side wall of the body 1. A drive motor 42 is disposed on the side wall of the U-shaped support plate 43. A second gear 44 located inside the U-shaped support plate 43 is disposed on the output shaft of the drive motor 42. A first gear 41 meshing with the second gear 44 is disposed on the side wall of the rotating shaft 2. This design drives the second gear 44 to rotate through the operation of the drive motor 42 in the drive rotation assembly 4. The second gear 44 drives the first gear 41 to rotate. The first gear 41 drives the rotating shaft 2 to rotate. The rotating shaft 2 drives the positioning disk 7 to rotate. The positioning disk 7 drives the square tube inside the positioning groove 21 to rotate.

[0034] Reference Figure 1 and Figure 2 A bearing 3 is installed at the connection between the rotating shaft 2 and the machine body 1. This improves the stability of the rotating part.

[0035] Reference Figure 1 and Figure 3 The top of the machine body 1 is equipped with a drive cutting assembly 6 for driving the laser cutting head 5 to cut square tubes;

[0036] The drive cutting assembly 6 includes a connecting plate 61 located on the top of the machine body 1. A longitudinal electric cylinder 62 is located at the bottom of the connecting plate 61, and an adjusting electric push rod 63 connected to the laser cutting head 5 is located at the bottom of the moving block of the longitudinal electric cylinder 62. This design drives the laser cutting head 5 on the adjusting electric push rod 63 to move longitudinally through the operation of the longitudinal electric cylinder 62 in the drive cutting assembly 6. The operation of the adjusting electric push rod 63 drives the laser cutting head 5 to move vertically, which facilitates the cutting operation of square tubes.

[0037] Reference Figure 3 and Figure 4 The vertical clamping drive assembly 8 includes a fixed plate 82 disposed at the end of the positioning disk 7. A vertical clamping electric push rod 81 is disposed on the side wall of the fixed plate 82. A mounting seat 83, connected to a vertical positioning roller 9, is disposed on the telescopic shaft of the vertical clamping electric push rod 81. A conveying motor 91 is disposed on the side wall of the mounting seat 83 and connected to the vertical positioning roller 9. This design uses the vertical clamping electric push rod 81 in the vertical clamping drive assembly 8 to drive the mounting seat 83 to move vertically. The mounting seat 83 then drives the vertical positioning roller 9 to move vertically, facilitating the clamping of the opposite vertical sides of the square tube. The conveying motor 91 drives the vertical positioning roller 9 to rotate, thus conveying and feeding the square tube.

[0038] Reference Figure 4 The longitudinal clamping drive assembly 10 includes a mounting plate 102 disposed at the end of the positioning disk 7. A longitudinal clamping electric push rod 101 is disposed on the side wall of the mounting plate 102. A connecting seat 103 connected to the longitudinal positioning roller 11 is disposed on the telescopic shaft of the longitudinal clamping electric push rod 101. This design drives the longitudinal clamping electric push rod 101 in the longitudinal clamping drive assembly 10 to move the longitudinal positioning roller 11 on the connecting seat 103 in the longitudinal direction, thereby clamping the two longitudinally opposite sides of the square tube.

[0039] Reference Figure 2 and Figure 3 The positioning disk 7 has a hollow shaft conductive slip ring 12 embedded at its end and sleeved on the side wall of the rotating shaft 2. Both the end of the positioning disk 7 and the side wall of the machine body 1 have wire holes 1001. This design facilitates the passage of wires to supply power to the conveyor motor 91, the vertical clamping electric push rod 81, and the longitudinal clamping electric push rod 101.

[0040] Reference Figures 1-4As an embodiment of this utility model: when it is necessary to cut a square tube, the square tube is passed through the positioning groove 21, and the vertical clamping electric push rod 81 in the pair of vertical clamping drive components 8 drives the mounting base 83 to move in the vertical direction. The pair of mounting bases 83 drives the pair of vertical positioning rollers 9 to move towards each other, clamping the vertically opposite side walls of the square tube. Then, the longitudinal clamping electric push rod 101 in the pair of longitudinal clamping drive components 10 drives the longitudinal positioning rollers 11 on the pair of connecting seats 103 to move towards each other, clamping the longitudinally opposite side walls of the square tube. This can adapt to the positioning and clamping of square tubes of different sizes. The vertical positioning rollers 9 are rotated by the operation of the conveying motor 91 to complete the feeding of the square tube, improve the stability of clamping and conveying, avoid displacement or vibration of the square tube during the cutting process, improve cutting accuracy, and improve cutting quality.

[0041] The rotating component 4 drives the positioning disk 7 on the rotating shaft 2 to rotate, and the rotation of the positioning disk 7 drives the square tube to rotate. In conjunction with the driving cutting component 6, the laser cutting head 5 performs the cutting operation on the square tube, which improves the practicality of this utility model.
