Description

Technical Field

[0001] This utility model relates to the technical field of busbar cutting equipment, specifically to cutting auxiliary tools used in the production and processing of busbars. Background Technology

[0002] Busbar trunking is a new type of enclosed conductive system that uses copper or aluminum as conductors, is supported by non-aluminous insulation, and is installed in a metal trough. It is mainly used for transmitting and distributing large currents and has advantages such as large current capacity, small voltage drop, low construction and operating costs, flexible power distribution, simple maintenance, safety and reliability, and space saving. It is widely used in various buildings and facilities such as factories, commercial buildings, hospitals, and airports. The side plates of the busbar trunking are important components of the busbar trunking equipment, usually referring to the left and right shell surfaces of the outer casing. They are mainly used to cover the openings on the outer casing, providing protection and support. They are generally fixed with screws or similar methods and are generally not disassembled after the equipment is put into operation. Some busbar trunking side plates are also designed as heat sinks to improve heat conduction performance and heat dissipation.

[0003] However, during the production and processing of busbar trunking, the side plates of the busbar trunking need to be cut according to the dimensional requirements. Currently, most methods for cutting busbar trunking side plates involve manually moving the side plates onto a cutting table, adjusting the cutting position, and then using a clamp to limit the position before cutting. This process is repeated to continuously cut the side plates, resulting in low production efficiency. Therefore, those skilled in the art have provided cutting auxiliary tools for busbar trunking production and processing to solve the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this utility model is to provide a cutting auxiliary tool for the production and processing of busbar trunking, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cutting auxiliary tool for busbar trunking production includes: a cutting table, a cutting groove on the end face of the cutting table corresponding to the cutting blade, positioning seats and limiting seats on both sides of the cutting groove for clamping and limiting the position of the busbar trunking side plate, and a groove on one side of one set of positioning seats and limiting seats on the end face of the cutting table, with a plurality of auxiliary rollers for assisting the feeding of the busbar trunking side plate evenly arranged inside the groove, the circumferential part of the auxiliary rollers extending to the top of the groove, and a feeding mechanism above the groove, the feeding mechanism including a fixed frame and an adjusting frame, wherein the fixed frame is installed on the upper end face of the cutting table and covers the groove, the adjusting frame is slidably installed inside the fixed frame, and a conveying roller for conveying the busbar trunking side plate is arranged inside the adjusting frame, the circumferential part of the conveying roller extending to the bottom of the adjusting frame, and the busbar trunking side plate is clamped between the conveying roller and the auxiliary roller.

[0007] Preferably, the upper end face of the cutting table is provided with a cylinder for driving the limit seat to move, and the output end of the cylinder is provided with an extension rod, which is installed on the back of the limit seat and pushes it to move.

[0008] Preferably, the fixed frame has through slots on both sides, the two ends of the adjusting frame extend into the interior of the two through slots and slide inside them, and the outer wall of the adjusting frame is provided with a second motor for driving the conveying roller to rotate at one end of one of the through slots.

[0009] Preferably, a first motor is provided at the top of the fixed frame, and a threaded rod is provided at the output end of the first motor. The threaded rod passes through the fixed frame and extends to its inner side. A sleeve is provided at the top of the adjusting frame at the position corresponding to the threaded rod. The sleeve is threadedly fitted onto the outer wall of the threaded rod, and the sleeve can push the adjusting frame to move inside the fixed frame through the rotation of the threaded rod.

[0010] Preferably, the inner cavity of the sleeve is provided with a threaded groove, and the threaded rod is threadedly installed in the inner cavity of the sleeve through the threaded groove.

[0011] Preferably, a fixed seat is provided on the side of the positioning seat away from the fixed frame. A proximity switch for monitoring the cutting length of the busbar side plate is embedded in the inner side of the fixed seat. A fixing bolt is provided on the end face of the fixed seat. Several threaded holes are evenly distributed in a straight line on the end face of the cutting table located below the fixed seat. The fixing bolt passes through the fixed seat and is threaded inside the threaded hole.

[0012] Preferably, the cylinder, proximity switch, first motor, and second motor are all connected to an external PLC controller.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] By setting a feeding mechanism on the cutting table, the busbar side plate can be clamped between the conveying roller and the auxiliary roller. The conveying roller and the auxiliary roller feed the busbar side plate, and then a proximity switch senses the position of the busbar side plate after feeding. An external PLC controller controls the busbar side plate to stop feeding, completing the automatic feeding and cutting position adjustment of the busbar side plate. Then, two sets of limit seats and positioning seats are used to simultaneously limit the main body of the busbar side plate and the busbar side plate to be cut, preventing the busbar side plate to be cut from being cut during the cutting process. The process involves shaking to prevent the busbar side plates from shifting during cutting and affecting the cutting quality, thus ensuring the quality of the busbar side plates. Finally, the cutting blade is used to cut the busbar side plate material after it has been positioned to complete the cutting work. The system can continuously transport the busbar side plates to the cutting table, control the feeding length of the busbar side plates, reduce the trouble of manually handling the busbar side plates and adjusting their cutting position, save time and labor, and improve the production efficiency of the busbar.

[0021] Combination Figures 1-4 As shown, a cutting groove 101 is provided on the end face of the cutting table 1 at the position corresponding to the cutting blade. Positioning seats 11 and limiting seats 12 for clamping and limiting the position of the busbar trough side plate are provided on both sides of the cutting groove 101. Furthermore, a groove 102 is provided on one side of one set of positioning seats 11 and limiting seats 12 on the end face of the cutting table 1. Several auxiliary rollers 14 for assisting the feeding of the busbar trough side plate are evenly arranged inside the groove 102. The circumferential part of the auxiliary rollers 14 extends to the top of the groove 102. A feeding mechanism is provided above the groove 102. The feeding mechanism includes a fixed frame 2 and an adjusting frame 3. The fixed frame 2 is installed on the upper end face of the cutting table 1 and covers the groove 102. The adjusting frame 3 is slidably installed inside the fixed frame 2. A conveying roller 31 for conveying the busbar trough side plate is provided inside the adjusting frame 3. The circumferential part of the conveying roller 31 extends to the bottom of the adjusting frame 3. The busbar trough side plate is clamped between the conveying roller 31 and the auxiliary rollers 14.

[0022] In one embodiment, both sides of the cutting groove 101 are provided with positioning seats 11 and limiting seats 12 for clamping and defining the position of the busbar trunking side plate. Furthermore, the upper surface of the cutting table 1 is provided with a cylinder 13 for driving the limiting seat 12 to move. The output end of the cylinder 13 is provided with an extension rod, which is installed on the back of the limiting seat 12 and pushes it to move. When limiting the busbar trunking side plate, the cylinder 13 can be used to drive the extension rod at its output end to extend, thereby moving the limiting seat 12 installed on the extension rod. The limiting seat 12 presses the busbar trunking side plate tightly against the inner side of the positioning seat 11, thus completing the clamping and limiting of the busbar trunking side plate. The two sets of limiting seats 12 and positioning seats 11 located on both sides of the cutting groove 101 can simultaneously limit the main body of the busbar trunking side plate and the busbar trunking side plate to be cut, preventing the busbar trunking side plate to be cut from shaking during the cutting process. This avoids the situation where the busbar trunking side plate to be cut is affected by shaking during the cutting process, thus ensuring the cutting quality of the busbar trunking side plate.

[0023] In one embodiment, the fixed frame 2 has through slots 201 on both sides, and the two ends of the adjusting frame 3 extend into the interior of the two through slots 201 and slide inside them. Furthermore, the outer wall of the adjusting frame 3 is provided with a second motor 32 for driving the conveying roller 31 to rotate at one end of one of the through slots 201. When adjusting the position of the adjusting frame 3, the adjusting frame 3 can drive the second motor 32 to slide inside the through slot 201 without interfering with the fixed frame 2, which facilitates the adjustment of the position of the adjusting frame 3.

[0024] In one embodiment, a first motor 21 is provided at the top of the fixed frame 2, and a threaded rod 22 is provided at the output end of the first motor 21. The threaded rod 22 passes through the fixed frame 2 and extends to its inner side. A sleeve 33 is provided at the top of the adjusting frame 3 at a position corresponding to the threaded rod 22. The sleeve 33 is threadedly fitted onto the outer wall of the threaded rod 22, and the sleeve 33 can push the adjusting frame 3 to move inside the fixed frame 2 through the rotation of the threaded rod 22. When adjusting the height of the conveying roller 31, the threaded rod 22 can be driven by the first motor 21. Rotation causes the sleeve 33, which is fitted onto the outer wall of the threaded rod 22 through the threaded groove 331, to move. During this movement, the sleeve 33 causes the adjusting frame 3 to slide inside the fixed frame 2, thereby adjusting the height of the conveying roller 31 installed inside the adjusting frame 3. The height of the conveying roller 31 can be adjusted according to the thickness of the busbar side plate, changing the size of the gap between the conveying roller 31 and the auxiliary roller 14, so that the gap between the conveying roller 31 and the auxiliary roller 14 is adapted to the thickness of the busbar side plate, which is suitable for conveying busbar side plates of different thicknesses.

[0025] In one embodiment, a fixing seat 15 is provided on the side of the positioning seat 11 away from the fixing frame 2. A proximity switch 16 for monitoring the cutting length of the busbar trunking side plate is embedded inside the fixing seat 15. A fixing bolt is provided on the end face of the fixing seat 15. A plurality of linearly distributed threaded holes 103 are evenly arranged on the end face of the cutting table 1 below the fixing seat 15. The fixing bolt passes through the fixing seat 15 and is threaded into the threaded holes 103. When the busbar trunking side plate is transported to the cutting table 1 for cutting, the proximity switch 16 installed inside the fixing seat 15 can sense the position of the busbar trunking side plate, detect whether the busbar trunking side plate is in place, and detect the position of the busbar trunking side plate. The information of the board's arrival is fed back to the external PLC controller, which then controls the busbar trunking side plate to stop feeding, thus realizing the automatic feeding of the busbar trunking side plate. Moreover, when adjusting the cutting length of the busbar trunking side plate according to requirements, the fixed seat 15 on the cutting table 1 can be moved to adjust the position of the proximity switch 16 on the fixed seat 15. Then, the fixing bolt is installed in the threaded hole 103 under the fixed seat 15 after the position is moved, which can complete the position adjustment and limit of the proximity switch 16. The position of the proximity switch 16 can be changed according to the cutting requirements, and the distance between the proximity switch 16 and the cutting blade can be adjusted to increase the feeding and cutting length of the busbar trunking side plate, which is highly practical.

[0026] The working principle of this utility model is as follows: During the production of busbar troughs, the side plate of the busbar trough can be clamped between the conveying roller 31 and the auxiliary roller 14. The conveying roller 31 and the auxiliary roller 14 convey the side plate of the busbar trough to the area below the cutting blade. Then, the proximity switch 16 senses the position of the side plate of the busbar trough and detects whether the side plate is in place. The information of the side plate being in place is fed back to the external PLC controller. The PLC controller controls the side plate of the busbar trough to stop feeding. At the same time, the PLC controller controls the cylinder 13 to work, causing the cylinder 13 to drive the extension rod at its output end to extend, and causing the limit seat 12 installed on the extension rod to move, so that the limit seat 12 moves the side plate of the busbar trough. The plate is pressed tightly against the inner side of the positioning seat 11, simultaneously limiting the main body of the busbar trunking side plate and the busbar trunking side plate to be cut, preventing the busbar trunking side plate to be cut from shaking during the cutting process. This avoids the situation where the busbar trunking side plate to be cut is affected by shaking during the cutting process, ensuring the cutting quality of the busbar trunking side plate. Finally, the PLC controller controls the cutting machine to work, using the cutting blade to cut the busbar trunking side plate after it is in the limited position. This process is repeated to complete the continuous feeding and cutting of the busbar trunking side plate, reducing the trouble of manually moving the busbar trunking side plate repeatedly and adjusting its cutting position, saving time and effort, and improving the production efficiency of the busbar trunking.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
