Description

Technical Field

[0001] This utility model relates to the field of junction box processing technology, specifically to a burr removal device for junction box processing. Background Technology

[0002] In marine electrical systems, junction boxes are critical components for connecting electrical elements, and their manufacturing quality directly affects the safety and stability of the marine power system. During the manufacturing process of marine junction boxes (such as metal sheet stamping, cutting, and injection molding), defects such as burrs, rough edges, or flash are easily generated on the edges of the workpiece. If these defects are not cleaned in time, they will not only affect the assembly accuracy and sealing performance of the junction box, but may also cause short circuits due to burrs piercing the insulation layer, and even pose safety hazards in special environments such as ship vibration and humidity. Therefore, the treatment of burrs on junction boxes is very important.

[0003] Existing junction boxes require clamping with fixtures for burr removal before processing to ensure stable operation. However, current fixtures are cumbersome to operate and time-consuming to set up, which increases processing difficulty and reduces work efficiency. Therefore, we provide a burr removal device for junction box processing. Utility Model Content

[0004] The purpose of this invention is to provide a burr removal device for junction box processing, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A burr removal device for junction box processing includes a cleaning device, which includes a processing table. A collection box is fixedly installed at the bottom rear end of the processing table, and fixing feet are fixedly installed on both sides of the bottom front end of the processing table.

[0007] A dust extraction unit is provided at the rear end of the processing table, and a fixing unit is provided at the top of the processing table.

[0008] The fixing unit includes four sets of through holes on the top of the processing table.

[0009] A further improvement of this utility model is that: a fixed inclined block is provided inside the through hole, and a piston rod is movably inserted into the inner walls on both sides of the bottom end of the fixed inclined block. A return spring is sleeved on the outer surface of the piston rod, and the bottom end of the piston rod is fixedly installed at the bottom of the inner end of the processing table.

[0010] A further improvement of this utility model is that a servo motor is fixedly installed on the left side support of the processing table, a drive rod is fixedly installed on the output end of the servo motor, and the other end of the drive rod is rotatably installed on the right side support plate of the processing table. The model of the servo motor is MSMF042L1U.

[0011] A further improvement of this utility model is that: half gears are fixedly sleeved on the outer surfaces of both ends of the drive rod, and brake gears are meshed with the top of the half gears.

[0012] A further improvement of this utility model is that: a slide rod is movably inserted inside the brake tooth plate, the slide rod is fixedly installed inside the grooves on both sides of the processing table, an elastic wire is sleeved on the outer surface of the front end of the slide rod, a grinding block is fixedly installed on the top of the brake tooth plate, and the slide rod can limit the movement of the brake tooth plate.

[0013] A further improvement of this utility model is that: the dust collection unit includes a dust collection hood fixedly installed at the rear end of the processing table, a pull-out box is movably inserted into the inside of the collection box, and a dust collection pump is fixedly installed on the left side of the collection box. The model of the dust collection pump is YFA-500.

[0014] A further improvement of this utility model is that: an air suction pipe is fixedly installed at the air suction end of the dust pump, the other end of the air suction pipe extends into the left side of the collection box, a dust suction pipe is fixedly installed at the right side of the collection box, and the other end of the dust suction pipe is fixedly installed inside the rear end of the dust suction hood.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] 1. This utility model provides a burr removal device for junction box processing. By setting fixed inclined blocks to contact the bottom of the junction box, the junction box squeezes the fixed inclined blocks, causing them to slide downwards along the piston rod, which in turn compresses the return spring until the junction box is completely submerged between the four sets of fixed inclined blocks. The squeezed fixed inclined blocks rebound and reset under the elastic counter-push force of the return spring. In this way, the four sets of fixed inclined blocks are used to position the junction box, which promotes convenient use and further improves work efficiency.

[0017] 2. This utility model provides a burr cleaning device for junction box processing. By setting up a dust pump to start synchronously, a negative pressure is formed in the collection box through the air extraction pipe. The shavings generated by grinding are absorbed by the dust extraction hood and enter the collection box through the dust extraction pipe. The shavings settle in the collection box. Later, the pull-out box can be pulled out to facilitate the cleaning of the collected shavings and prevent the shavings from floating around, which can improve the quality of the surrounding environment.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] like Figure 1-5 As shown, this utility model provides a burr cleaning device for junction box processing, including a cleaning device 1. The cleaning device 1 includes a processing table 2. A collection box 4 is fixedly installed at the bottom rear end of the processing table 2. Fixed feet 3 are fixedly installed on both sides of the bottom front end of the processing table 2. A dust suction unit is provided at the rear end of the processing table 2. A fixing unit is provided at the top of the processing table 2. The fixing unit includes a through hole 21 opened at the top of the processing table 2. Four sets of through holes 21 are provided. A fixing inclined block 22 is provided inside the through hole 21. A piston rod 23 is movably inserted into the inner wall of both sides of the bottom end of the fixing inclined block 22. A return spring 24 is sleeved on the outer surface of the piston rod 23. The bottom end of the piston rod 23 is fixedly installed at the bottom end of the processing table 2.

[0027] Furthermore, by placing the junction box to be processed on the top of the processing table 2, with its two sides corresponding between the two sets of grinding blocks 211, it is pushed between the two sets of grinding blocks 211. The bottom of the junction box presses against the fixed inclined block 22, causing it to slide down along the piston rod 23, which in turn compresses the return spring 24 until the junction box is completely submerged between the four sets of fixed inclined blocks 22. The compressed fixed inclined block 22 rebounds and resets under the elastic counter-push force of the return spring 24, thereby using the four sets of fixed inclined blocks 22 to position the junction box.

[0028] Example 2

[0029] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, a servo motor 25 is fixedly installed on the left side bracket of the processing table 2, a drive rod 26 is fixedly installed on the output end of the servo motor 25, the other end of the drive rod 26 is rotatably installed on the right side support plate of the processing table 2, half gears 27 are fixedly sleeved on the outer surfaces of both ends of the drive rod 26, a brake tooth plate 28 is meshed with the top of the half gear 27, a slide rod 29 is movably inserted into the inside of the brake tooth plate 28, the slide rod 29 is fixedly installed in the grooves on both sides of the processing table 2, an elastic wire 210 is sleeved on the outer surface of the front end of the slide rod 29, and a grinding block 211 is fixedly installed on the top of the brake tooth plate 28.

[0030] Furthermore, the output end of the servo motor 25 drives the drive rod 26 to rotate, and the half gears 27 at both ends of the drive rod 26 rotate accordingly. When the half gears 27 mesh with the brake tooth plate 28, they push the brake tooth plate 28 to slide forward along the slide rod 29. At this time, the elastic wire 210 is squeezed. When the half gears 27 disengage, the elastic wire 210 stretches and pulls the brake tooth plate 28 to reset, forming a reciprocating linear motion, and driving the grinding block 211 to grind the burrs on the edge of the junction box.

[0031] Example 3

[0032] like Figure 1-5 As shown, based on embodiments 1-2, this utility model provides a technical solution: preferably, the dust collection unit includes a dust collection hood 45 fixedly installed at the rear end of the processing table 2, a pull-out box 41 movably inserted into the inside of the collection box 4, a dust collection pump 42 fixedly installed on the left side of the collection box 4, an air suction pipe 43 fixedly installed at the suction end of the dust collection pump 42, the other end of the air suction pipe 43 extending into the left side of the collection box 4, a dust collection pipe 44 fixedly installed on the right side of the collection box 4, and the other end of the dust collection pipe 44 fixedly installed inside the rear end of the dust collection hood 45.

[0033] Furthermore, the vacuum pump 42 starts simultaneously, creating negative pressure in the collection box 4 through the suction pipe 43. The debris generated during grinding is absorbed by the vacuum hood 45 and enters the collection box 4 through the vacuum pipe 44. The debris settles in the collection box 4, and later the pull-out box 41 is pulled outward to facilitate the cleaning of the collected debris.

[0034] The solution uses a PLC as the core control component. The PLC establishes a connection with the servo motor 25 through RS-485 communication. When the servo motor 25 needs to be started, the PLC sends a start command to the servo motor 25 to start it.

[0035] The working principle of this burr removal equipment for junction box processing will be explained in detail below.

[0036] like Figure 1-5 As shown, during use, the junction box to be processed is placed on the top of the processing table 2, with its two sides corresponding between the two sets of grinding blocks 211. It is then pushed between the two sets of grinding blocks 211, causing the bottom of the junction box to press against the fixed inclined blocks 22, which slide downwards along the piston rod 23. This compresses the return spring 24 until the junction box is completely submerged between the four sets of fixed inclined blocks 22. The compressed fixed inclined blocks 22 then spring back to their original position under the elastic counterforce of the return spring 24. Thus, the four sets of fixed inclined blocks 22 are used to position the junction box. The output of the servo motor 25 drives the drive rod 26 to rotate, and the half-gears 27 at both ends of the drive rod 26 rotate accordingly. When the half gear 27 engages with the brake tooth plate 28, it pushes the brake tooth plate 28 to slide forward along the slide rod 29. At this time, the elastic wire 210 is squeezed. When the half gear 27 disengages, the elastic wire 210 stretches and pulls the brake tooth plate 28 back to its original position, forming a reciprocating linear motion. This motion also drives the grinding block 211 to grind the rough edges of the junction box. During the grinding process, the dust pump 42 starts simultaneously and forms a negative pressure in the collection box 4 through the suction pipe 43. The grinding debris is absorbed by the dust hood 45 and enters the collection box 4 through the dust suction pipe 44. The debris settles in the collection box 4. Later, the pull-out box 41 is pulled outward to facilitate the cleaning of the collected debris.

[0037] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
