Description
Technical Field
[0001] The invention belongs to the technical field of copper busbar processing, and in particular relates to a copper busbar heat shrink tube cutting machine. Background Art
[0002] After mechanical processing, the copper busbar needs to be insulated by a heat shrink tube on its outer surface. After heat shrinkage, the heat shrink tube completely wraps and adheres to the outer surface of the copper busbar. In subsequent operations, part of the heat shrink tube needs to be removed at certain locations for combined conduction.
[0003] At present, the removal of heat shrink tubes is generally done manually. Manual cutting is simple and convenient, but it also has major defects. Manual operation efficiency is low. The tube wall of the high-pressure heat shrink tube is relatively hard after shrinkage, and the operator needs to cut it repeatedly. The cutting efficiency is very low and it is easy to hurt the hands. Workers cannot accurately grasp the cutting depth, which may cause the heat shrink tube to not fall off due to shallow cutting, or damage the copper busbar due to excessive cutting. In addition, manual cutting is prone to edge burrs or uneven tangents.
[0004] In the prior art, although mechanized cutting of the heat shrink tube of the copper busbar can be achieved, most of them use a spring-driven cutter to cut the heat shrink tube on the surface of the copper busbar. The cutting depth of such a device is affected by the compression degree of the spring, and for copper buses of different shapes or thicknesses, the compression degree of the spring is different, and the cutting depth is also different. The greater the deformation of the spring, the greater the elastic force on the cutter, the greater the force of the cutter on the copper busbar, and the greater the cutting depth, which is very easy to cause damage to the copper busbar during cutting. In addition, in the prior art, it is difficult to accurately locate the cutting position. Summary of the invention

[0042] The variable track fixing frame 5 includes a transverse bracket 25, a vertical bracket 26, a transverse guide rail 27 and a vertical guide rail 28. The transverse bracket 25 is arranged in an inverted L shape. The transverse bracket 25 is arranged on the side of the transverse clamping plate 19 close to the annular non-destructive depth-fixing cutting device 6.

[0046] When in use, the processing position of the copper bar is first marked, and the copper bar to be processed is inserted into the clamping through hole 17 from one side of the extension support plate 42, and then the line laser 7 is turned on, and the copper bar is adjusted so that the marked part of the copper bar is aligned with the light emitted by the line laser 7. The line laser 7 accurately positions the cutting part of the copper bar, and then the horizontal clamping assembly 15 and the vertical clamping assembly 16 are started. In the initial state, the side edges of the horizontal clamping plate 19 and the vertical clamping plate 18 are respectively aligned with the side edges of the clamping through hole 17. When the electric push rod 20 of the horizontal clamping assembly 15 drives one of the racks 22 to move, the rack 22 drives the other rack 22 to move synchronously through the central gear 21, and the two racks 22 drive the two horizontal clamping plates 19 to move synchronously along the first direction The copper bar is moved toward each other and is close to the copper bar to clamp it horizontally. When the electric push rod 20 of the vertical clamping assembly 16 drives one of the racks 22 to move, the rack 22 drives the other rack 22 to move synchronously through the central gear 21. The two racks 22 drive the two vertical clamping plates 18 to move toward each other along the second direction to approach the copper bar to clamp it vertically. When the side walls of the vertical clamping plate 18 and the horizontal clamping plate 19 are tightly fitted with the side walls of the copper bar, the vertical clamping plate 18 and the horizontal clamping plate 19 drive the copper bar to move and align with the axis of the annular bracket 8. The support plate 42 is extended to support the copper bar. When the horizontal clamping plate 19 and the vertical clamping plate 18 move, the horizontal guide rail 27 and the vertical guide rail 28 are driven to move through the horizontal bracket 25 and the vertical bracket 26 respectively. The horizontal guide rail 27 and the vertical guide rail 28 form a rectangular frame, and the rectangular frame changes with the movement of the horizontal clamping plate 19 and the vertical clamping plate 18. The distances between the four sides of the rectangular frame and the side walls of the copper bar are equal. When the rectangular frame changes, the cutting assembly 11 is driven to move closer to or away from the axis of the annular rotating frame 9 through the fixed rail sliding shaft 12. The cutting assembly 11 drives the elastic pull rod 10 to extend or shorten. The elastic pull rod 10 uses elastic force to keep the circumferential side wall of the fixed rail sliding shaft 12 always in contact with the inner wall of the rectangular frame. The fixed rail sliding shaft 12 keeps the cutting blade 33 of the cutting assembly 11 in contact with the side wall of the copper bar. The driving motor 36 and the cutting motor 34 are started. The cutting motor 34 drives the cutting blade 33 to rotate for cutting. The driving motor 36 drives the gear 37 to rotate The gear 37 drives the annular rotating frame 9 to rotate through the gear ring 38, and the annular rotating frame 9 drives the elastic pull rod 10 and the cutting assembly 11 to rotate around the circumference of the copper bar. The elastic pull rod 10 pulls the fixed track sliding shaft 12 through the cutting assembly 11 so that the circumferential side wall of the fixed track sliding shaft 12 always keeps in contact with the inner wall of the rectangular frame. Therefore, during the rotation process, the fixed track sliding shaft 12 moves along the inner wall of the rectangular frame and drives the elastic pull rod 10 to extend and retract. Since the distances from the four sides of the rectangular frame to the side walls of the copper bar are equal in length, during the rotation process, the distance from the cutting assembly 11 to the side walls of the copper bar remains constant, the cutting assembly 11 fits with the side walls of the copper bar, and the cutter applies uniform and stable force to the copper bar to ensure uniform segmentation. While ensuring that the heat shrink tube is completely segmented, damage to the copper bar is avoided to the greatest extent.
