Description

Technical Field

[0001] The utility model relates to the technical field of bus duct cutting, in particular to a bus duct cutting machine. Background Art

[0002] Modern high-rise buildings and large workshops require huge amounts of electrical energy, and in the face of this huge load, the powerful current of hundreds or thousands of amperes requires the use of safe and reliable conduction equipment, and the busbar system is a good choice. The busbar system is a distribution device that efficiently transmits current, especially adapted to the needs of economical and reasonable wiring in increasingly tall buildings and large-scale factories.

[0003] Bus duct is a closed metal device composed of copper and aluminum busbars, which is used to distribute high power to various components of the distributed system. It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects. Compared with traditional cables, it fully demonstrates its superiority in large current transmission. At the same time, due to the use of new technologies and new processes, the contact resistance and temperature rise at the connection points at both ends of the bus duct and the plug-in points of the branch ports are greatly reduced, and high-quality insulating materials are used in the bus duct, thereby improving the safety and reliability of the bus duct and making the entire system more perfect. The bus duct is characterized by series matching, commercial production, small size, large capacity, short design and construction period, and convenient assembly and disassembly.

[0004] The bus duct is connected and installed in sections through connectors, so the bus duct needs to be cut and segmented during the production or installation process. However, the existing bus duct cutting device is not convenient for quickly replacing the saw blade when in use, and it is not convenient to control the cutting depth of the saw blade, which affects the use efficiency and cutting accuracy. Utility Model Content

[0005] The utility model provides a busbar cutting machine, which solves the above-mentioned technical problems.

[0006] The utility model solves the above-mentioned technical problems as follows:

[0007] A busbar duct cutting machine comprises a fixed frame, a limit frame, a baffle and a limit plate, the limit frame is welded with a baffle, a motor is installed on one side of the limit frame, the output end of the motor passes through the limit frame, and the transmission shaft of the motor is installed with a fixed seat through a spline, the transmission shaft of the motor is located between the limit frame and the fixed seat and is sleeved with a fixed frame, the transmission shaft of the motor is located between the fixed frame and the limit frame and is sleeved with a cushion block, a limit column is provided on the fixed seat, a limit plate and an end cover are installed on the transmission shaft at the side of the saw blade away from the fixed seat, a limit block is provided at the end of the transmission shaft, the fixed frame, the fixed seat, the saw blade and the limit plate are clamped and limited on the transmission shaft by the cushion block and the end cover, and a slot is provided on the end cover, and the end cover is connected to the transmission shaft through the slot and the limit block.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, the transmission shaft is rotatably mounted in the fixing frame and the limiting plate via a shaft sleeve or a bearing.

[0010] The beneficial effects of adopting the above further scheme are:

[0011] The drive shaft can be installed by rotating the sleeve or bearing to effectively reduce the friction between the fixed frame and the limit plate, reduce the wear of parts and components, and extend the service life of the equipment. The use of sleeves or bearings can ensure the stable rotation of the drive shaft, reduce the vibration and noise of the equipment caused by unstable transmission, and improve the stability and smooth operation of the equipment. The design of rotating installation with sleeves or bearings facilitates the maintenance and maintenance of the equipment. Operators can more easily perform maintenance work such as lubrication and replacement of bearings, which improves the maintainability of the equipment. Stable rotation of the drive shaft can improve the working accuracy of the equipment, ensure the accuracy and consistency of bus duct cutting, and thus improve the quality and accuracy of product processing.

[0012] Furthermore, the length of the limiting column is adapted to the thickness of the saw blade.

[0013] The beneficial effects of adopting the above further scheme are:

[0014] By inserting the limit column into the saw blade, the saw blade can be effectively fixed on the fixed seat, which increases the stability of the saw blade and the verticality during cutting, and improves the cutting accuracy. The insertion and removal of the limit column is very simple and convenient, and the operator can easily replace the saw blade or perform maintenance, which improves the operability and maintenance efficiency of the equipment. By fixing the limit column, the saw blade can be prevented from excessive stress and loss due to vibration or friction, extending the service life of the saw blade and reducing the frequency and cost of replacing the saw blade. Since the saw blade is stably fixed on the fixed seat, the operator does not need to frequently adjust the position of the saw blade when cutting, which improves the convenience and work efficiency of operation and saves time and labor costs.

[0015] Furthermore, one end of the fixing frame is in contact with the baffle plate, and one end of the limiting plate is in contact with the fixing frame. The fixing frame and the limiting plate are limited by the baffle plate to prevent the fixing frame and the limiting plate from rotating together with the transmission shaft.

[0016] The beneficial effects of adopting the above further scheme are:

[0017] By limiting the rotation of the fixing frame and the limit plate by the baffle, it is possible to effectively prevent the fixing frame and the limit plate from rotating with the transmission shaft due to misoperation or other reasons, thereby ensuring the stability and safety of the equipment. The setting of the baffle can fix the position of the limit plate and the fixing frame, preventing them from loosening or shifting with the rotation of the transmission shaft, thereby ensuring the stability and reliability of the equipment during operation. By limiting the rotation of the fixing frame and the limit plate by the baffle, it is possible to reduce the wear and friction between the parts of the equipment, extend the service life of the equipment, and reduce the maintenance cost. Preventing the fixing frame and the limit plate from rotating with the transmission shaft can reduce unnecessary energy loss, improve the energy efficiency performance of the equipment, and reduce energy consumption. The setting of the baffle can reduce the difficulty of equipment maintenance, reduce the complexity of maintenance, and save maintenance time and labor costs.

[0018] The beneficial effects of the utility model are:

[0019] By replacing different limit plates, the distance of the saw blade protruding from the limit plate can be adjusted, thereby accurately controlling the cutting depth. This allows operators to flexibly adjust according to specific needs to meet the requirements of cutting bus ducts of different thicknesses or depths.

[0020] When it is necessary to remove the limit plate and replace the saw blade, the operation is very simple and convenient. The user only needs to remove the pad, and then move the fixing frame, fixing seat, saw blade, limit plate and end cover backwards to complete the corresponding maintenance and replacement work. This design makes the maintenance of the equipment more efficient and quick.

[0021] Through the design of the limit plate and end cap, the position of the saw blade and the cutting depth can be precisely controlled. This ensures the cutting accuracy and consistency, so that the size and shape of the bus duct can meet the design requirements and improve the quality of the product.

[0022] The setting of the baffle and the limit plate plays a limiting role during the operation of the equipment, preventing the fixed frame and the limit plate from rotating with the transmission shaft. This design enhances the stability and safety of the equipment, reduces the probability of accidents, and protects the safety of operators.

[0034] Embodiment 1

[0035] A busbar duct cutting machine comprises a fixing frame 3, a limiting frame 4, a baffle 5 and a limiting plate 6, the limiting frame 4 is welded with the baffle 5, a motor 2 is installed on one side of the limiting frame 4, the output end of the motor 2 passes through the limiting frame 4, and the transmission shaft 11 of the motor 2 is installed with a fixing seat 9 through a spline, the transmission shaft 11 of the motor 2 is located between the limiting frame 4 and the fixing seat 9 and is sleeved with the fixing frame 3, the transmission shaft 11 of the motor 2 is located between the fixing frame 3 and the limiting frame 4 and is sleeved with a cushion block 1, a card slot 12 is opened on the cushion block 1, and the cushion block 1 is clamped on the transmission shaft 11 through the card slot 12. When the limiting plate 6 and the saw blade 7 need to be disassembled and assembled, the user first removes the cushion block 1, and then moves the fixing frame 3, the fixing seat 9, the limiting plate 6 of the saw blade 7 and the end cover 8 backward to separate the end cover 8 from the limiting block 10, and then removes the end cover 8, the limiting plate 6 and the saw blade 7 in turn for replacement.

[0036] A limiting column 13 is provided on the fixed seat 9. The length of the limiting column 13 matches the thickness of the saw blade 7. The limiting column 13 is inserted into the saw blade 7 to limit the connection between the saw blade 7 and the fixed seat 9. The limiting column 13 is inserted into the saw blade 7 to effectively fix the saw blade 7 on the fixed seat 9, thereby increasing the stability of the saw blade 7 and the verticality during cutting, and improving the cutting accuracy. The insertion and removal of the limiting column 13 are very simple and convenient, and the operator can easily replace the saw blade 7 or perform maintenance, thereby improving the operability and maintenance efficiency of the equipment. By fixing the limiting column 13, the saw blade 7 can be prevented from being subjected to excessive stress and loss due to vibration or friction, thereby extending the service life of the saw blade 7 and reducing the frequency and cost of replacing the saw blade 7. Since the saw blade 7 is stably fixed on the fixed seat 9, the operator does not need to frequently adjust the position of the saw blade 7 during cutting, which improves the convenience and work efficiency of operation and saves time and labor costs. A limit plate 6 and an end cover 8 are installed on the side of the transmission shaft 11 that is away from the fixed seat 9. By replacing different limit plates 6, the distance that the saw blade 7 is exposed from the limit plate 6 can be controlled, thereby controlling the cutting depth of the saw blade 7.

[0037] One end of the fixed frame 3 is fitted with the baffle 5, and one end of the limit plate 6 is fitted with the fixed frame 3. The fixed frame 3 and the limit plate 6 are limited by the baffle 5 to prevent the fixed frame 3 and the limit plate 6 from rotating with the transmission shaft 11. By limiting the rotation of the fixed frame 3 and the limit plate 6 by the baffle 5, it can be effectively prevented that the fixed frame 3 and the limit plate 6 rotate with the transmission shaft 11 due to misoperation or other reasons, thereby ensuring the stability and safety of the equipment. The setting of the baffle 5 can fix the position of the limit plate 6 and the fixed frame 3, prevent them from loosening or offsetting with the rotation of the transmission shaft 11, and ensure the stability and reliability of the equipment during operation. By limiting the rotation of the fixed frame 3 and the limit plate 6 by the baffle 5, the wear and friction between the parts of the equipment can be reduced, the service life of the equipment can be extended, and the maintenance cost can be reduced. Preventing the fixed frame 3 and the limit plate 6 from rotating with the transmission shaft 11 can reduce unnecessary energy loss, improve the energy efficiency performance of the equipment, and reduce energy consumption.

The transmission shaft 11 is rotatably installed in the fixed frame 3 and the limit plate 6 through a sleeve or a bearing. The rotational installation of the transmission shaft 11 through the sleeve or the bearing can effectively reduce the friction between the fixed frame 3 and the limit plate 6, reduce the wear degree of the parts, and extend the service life of the equipment. The use of the sleeve or the bearing can ensure the stable rotation of the transmission shaft 11, reduce the vibration and noise of the equipment caused by the unstable transmission, and improve the stability and running stability of the equipment. The design of the sleeve or the bearing rotation installation facilitates the maintenance and maintenance of the equipment. The operator can more easily perform maintenance work such as lubrication and replacement of bearings, thereby improving the maintainability of the equipment. The stable rotation of the transmission shaft 11 can improve the working accuracy of the equipment, ensure the accuracy and consistency of the busbar cutting, thereby improving the quality and accuracy of product processing. A card slot 12 is provided on the end cover 8, and the end cover 8 is connected to the transmission shaft 11 through the card slot 12 and the limit block 10.

[0039] A bus duct cutting machine based on Example 1 is used:

[0040] By replacing different limit plates 6, the distance of the saw blade 7 exposed from the limit plate 6 can be adjusted, thereby accurately controlling the cutting depth. This allows the operator to flexibly adjust according to specific needs to meet the requirements of cutting bus ducts of different thicknesses or depths.

[0041] When it is necessary to disassemble the limit plate 6 and replace the saw blade 7, the operation is very simple and convenient. The user only needs to remove the cushion block 1, and then move the fixing frame 3, the fixing seat 9, the saw blade 7, the limit plate 6 and the end cover 8 backward to complete the corresponding maintenance and replacement work. This design makes the maintenance of the equipment more efficient and quick.

[0042] The position and cutting depth of the saw blade 7 can be precisely controlled by the design of the stop plate 6 and the end cap 8. This ensures the accuracy and consistency of the cutting, so that the size and shape of the bus duct can meet the design requirements and improve the quality of the product.

[0043] The baffle 5 and the limit plate 6 play a limiting role in the operation of the equipment, preventing the fixing frame 3 and the limit plate 6 from rotating with the transmission shaft 11. This design enhances the stability and safety of the equipment, reduces the probability of accidents, and protects the safety of operators.
