Description

Technical Field

[0001] The present invention relates to the field of cutting devices, and in particular to a cutting device for processing a bus duct shell. Background Art

[0002] In the busbar trunking shell processing industry, cutting is a key process, and its equipment performance directly affects production efficiency and product quality. However, existing busbar trunking shell cutting devices have many problems that need to be solved.

[0003] Traditional cutting devices often use manual adjustment to position the busbar housing. For example, manually turning a knob to adjust the position of the stop plate is cumbersome and time-consuming. Positioning accuracy relies heavily on operator experience, making consistency difficult to ensure. Furthermore, the positioning mechanisms of some devices lack the ability to adapt to housings of varying widths. Frequent replacement or adjustment of positioning components is required to accommodate busbar housings of varying specifications, severely limiting production efficiency.

[0004] In terms of protection and safety performance, the protection measures of most cutting devices are not perfect. The debris and sparks generated during the cutting process are easy to fly everywhere, which not only threatens the safety of the operator, but also may damage the surrounding equipment. Moreover, the existing protective structures are mostly single baffle designs, which cannot fully cover the cutting area, and the protective effect is limited. At the same time, the electric saws of some devices lack effective protection when not in operation. The electric saws are exposed to the outside, and there is a risk of accidental injury to the operator. The patent document with announcement number CN116851822B provides a cutting device for processing bus duct shells. Although the protective structure in the device can prevent the cutting structure from injuring the staff to a certain extent, the protective measures are not perfect in preventing debris and sparks from flying and causing damage to the surrounding equipment, and fail to fully consider the safety of the equipment in the entire working environment.

[0005] In terms of debris collection, the debris collection method of traditional cutting devices is relatively simple and crude. Usually, it only relies on the inclined design of the workbench surface to allow the debris to slide naturally to the collection area, and there is a lack of active collection means. This method causes debris to easily accumulate in the gaps of the workbench or the surrounding area, making it difficult to clean, and the accumulation of metal debris may affect the normal operation of the equipment, increasing the risk of equipment failure and maintenance costs. Although the patent document CN116851822B uses a method of collecting cutting debris through a storage structure, and although it solves the problem of debris spillage to a certain extent, there is still room for further improvement in the collection efficiency and the collection effect of different types of debris (especially the collection effect of some small debris is not ideal).

[0006] Furthermore, existing cutting devices lack effective linkage control between their various functional modules. Positioning, clamping, cutting, and protection are often performed independently, preventing automation and requiring extensive manual intervention, making them difficult to adapt to the demands of modern, efficient production. Consequently, developing a busbar trunking shell cutting device with efficient positioning guidance, comprehensive protection, automatic debris collection, and automated linkage is an urgent need for the industry. Summary of the Invention

[0018] Furthermore, the outer wall of the main shaft is formed with limiting grooves in an array at equal angles along the circumferential direction, and the inner wall of the sleeve is formed with limiting flanges in an array at equal angles along the circumferential direction, and the limiting flanges are connected to the limiting grooves in a one-to-one correspondence.

[0033] Third: The main baffle, auxiliary baffle and top baffle in this device work together to form a semi-enclosed splash-proof area. Combined with the fire curtain, it blocks the splashing of sparks and debris, and the air pump blows air to prevent the overflow of debris, effectively ensuring the safety of the operator. At the same time, during the processing, the operator can observe the cutting status of the workpiece through the observation window. At this time, the electric saw is within the coverage of the protective structure, avoiding the risk of accidental touch and reducing the incidence of safety accidents.

[0044] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] refer to Figures 1 to 8 , a cutting device for processing a bus duct shell, comprising:

[0046] A workbench 2 is formed with a perforation 3 in the middle. An electric saw 9 connected to the output end of a pneumatic slide 10 is provided on one side of the workbench 2. Positioning mechanisms 11 are provided on both sides of the electric saw 9. Each positioning mechanism 11 includes two curved frames 17 slidably provided at the lower end of the workbench 2. The upper end of each curved frame 17 is fixedly connected to a carrier 23. A conical rubber wheel 22 is rotatably provided on the carrier 23. A top block 26 is slidably provided on both sides of the conical rubber wheel 22.

[0047] A top plate 33 (such as Figure 3 As shown), a touch pressure sensor 37 is provided on the side of the top plate 33 away from the electric saw 9;

[0048] A splash-proof mechanism 38 is provided at the upper end of the perforation 3, and the splash-proof mechanism 38 includes a main baffle 39 fixedly connected to the workbench 2, and auxiliary baffles 49 are slidingly provided on both sides of the main baffle 39. The upper end of the main baffle 39 is rotatably connected to the top baffle 42, and the side where the two auxiliary baffles 39 are close to each other is fixedly connected to the air pipe 51.

[0049] When the device is in operation, the shell 1 to be cut is pushed in along the workbench 2. During this process, the positioning mechanism 11 will set the specific position of the conical rubber wheel 22 in advance according to the width of the shell 1, ensuring that the two sides of the shell 1 will be pressed tightly by the corresponding conical rubber wheels 22 during the pushing process, and the shell 1 in the feeding process is guided and positioned. Its end pushes the top plate 33 to trigger the touch pressure sensor 37, and the sensor signal is transmitted to the controller. The controller controls the positioning mechanism 11 to start. After the positioning mechanism 11 is started, it will drive the top blocks 26 at the upper ends of the corresponding two curved frames 17 to press and position the shell 1, ensuring that the shell 1 will not move during the cutting process.

[0050] During the cutting process, the pneumatic slide 10 drives the electric saw 9 to move to the cutting position, and the splash-proof mechanism 38 starts and drives the main baffle 39, the auxiliary baffle 49 and the top baffle 42 to form a closed splash-proof area. Then, after the processing is completed, the air pipe 51 blows air into the cutting area to blow off the debris, and the debris falls through the perforation 3.

[0051] In order to achieve the simultaneous approach or separation of the two curved frames 17, and then drive the carrier 23 to move through the curved frame 17, so that the conical rubber wheel 22 can cope with shells 1 of different widths, so that shells 1 of different widths can be tightened by the two relatively arranged conical rubber wheels 22 before positioning, thereby guiding the positioning of the shells 1 during the loading process, the following features are specifically provided:

[0052] The positioning mechanism 11 further includes a bidirectional screw rod 30 rotatably arranged below the workbench 2. The bidirectional screw rod 30 is rotatably connected to the workbench 2 through a rod seat. An auxiliary motor 31 (such as Figure 7 As shown), the output end of the auxiliary motor 31 is coaxially fixedly connected to the bidirectional screw rod 30;

[0053] Two threaded sleeves 29 are connected to the bidirectional screw rod 30, and each threaded sleeve 29 is fixedly connected to a slide 28. The two sides of the slide 28 are respectively provided with a limit side plate 32 fixedly connected to the lower end of the workbench 2 (such as Figure 3 As shown), the slide 28 is slidably connected to the limiting side plate 32, and the two slides 28 are respectively fixed to the lower ends of the two curved frames 17 (as shown Figure 7 shown).

[0054] After the auxiliary motor 31 is started, it drives the bidirectional screw 30 to rotate. Because the threads at both ends of the bidirectional screw 30 rotate in opposite directions, the two threaded sleeves 29 will perform opposite linear motion on the screw. The threaded sleeves 29 drive the slide 28 to slide along the limiting side plates 32, thereby causing the two curved frames 17 connected to the slide 28 to move closer or farther together. In this way, the spacing between the two relatively arranged tapered rubber wheels 22 can be quickly adjusted according to the actual width of the busbar duct housing 1, ensuring that housings 1 of different widths are stably pressed against the tapered rubber wheels 22 during the pushing process.

[0055] In order to drive the two conical rubber wheels 22 in the positioning mechanism 11 to rotate in opposite directions, the following features are specifically provided:

[0056] The positioning mechanism 11 further includes a main shaft 13 rotatably arranged in the middle of the curved frame 17, and a main motor 12 (such as Figure 7 As shown), the output end of the main motor 12 is coaxially fixedly connected to the main shaft 13;

[0057] The outer coaxial sliding sleeve of the main shaft 13 is provided with two shaft sleeves 15 (such as Figure 7 and Figure 8 As shown in FIG5 , a main bevel gear 18 is fixedly connected to the outside of each sleeve 15. The main bevel gear 18 is rotatably connected to the curved frame 17 via the bevel gear frame. The upper end of the main bevel gear 18 is rotatably provided with a secondary bevel gear 19 meshing therewith. The secondary bevel gear 19 is coaxially fixedly connected to a main pin 20. The upper end of the main pin 20 is coaxially fixedly connected to the corresponding tapered rubber wheel 22. The middle part of the main pin 20 is rotatably connected to the corresponding carrier 23.

[0058] The upper end of the workbench 2 is formed with a main bar hole 7 (such as Figure 6 As shown in FIG), each main bar hole 7 is provided with a secondary bar hole 8 on both sides, and a positioning bolt 21 is provided on both sides of the main pin 20 for sliding connection with the secondary bar hole 8. The upper end of the positioning bolt 21 is fixedly connected to the carrier 23, and the lower end passes through the secondary bar hole 8 and is fixedly connected to the upper end of the curved frame 17 (as shown in FIG). Figure 7 shown).

[0059] When the main motor 12 drives the main shaft 13 to rotate, the main shaft 13 drives the main bevel gear 18 to rotate through the shaft sleeve 15. The main bevel gear 18 meshes with the secondary bevel gear 19, transmitting power to the main pin 20, which in turn drives the tapered rubber wheel 22 to rotate. When the curved frame 17 moves under the drive of the bidirectional screw 30, the main pin 20 slides along the main bar hole 7, and the positioning bolt 21 moves within the secondary bar hole 8. This ensures that the tapered rubber wheel 22 can continue to rotate during the process of adjusting its position, achieving continuous guidance for shells 1 of different widths.

[0060] In order to ensure that after the curved frame 17 drives the sleeve 15 to move along the axis of the main shaft 13, the main shaft 13 can still drive the main bevel gear 18 to rotate through the sleeve 15, that is, the main shaft 13 and the sleeve 15 will not rotate relative to each other, but only slide relative to each other along the axis of the main shaft 13, the following features are specifically provided:

[0061] The outer wall of the main shaft 13 is formed with limiting grooves 14 in an array of equal angles along the circumferential direction (such as Figure 8 As shown), the inner wall of the sleeve 15 is formed with a limiting flange 16 in an array at equal angles along the circumferential direction, and the limiting flange 16 is connected to the limiting groove 14 in a one-to-one correspondence.

[0062] When the curved frame 17 drives the sleeve 15 to move along the axis of the main shaft 13, the limiting flange 16 engages with the limiting groove 14. The two cooperate to limit the relative rotation between the sleeve 15 and the main shaft 13, so that the rotational power of the main shaft 13 can be reliably transmitted to the sleeve 15 and the main bevel gear 18. At the same time, this structure allows the sleeve 15 and the main shaft 13 to slide relative to each other along the axis, ensuring that power transmission is not affected when adjusting the spacing between the tapered rubber wheels 22.

[0063] In order to drive the top block 26 to move so as to rigidly position and clamp the housing 1 and prevent the housing 1 from moving during the cutting process, the following features are also provided:

[0064] The upper end of the carrier 23 is fixedly connected to a cylinder 24 (such as Figure 6 As shown), the output end of the cylinder 24 is fixedly connected to a connecting push plate 25, and the side of the connecting push plate 25 away from the cylinder 24 is fixedly connected to two top blocks 26 respectively;

[0065] An anti-skid pad 27 is fixedly connected to the side of the top block 26 away from the cylinder 24 .

[0066] After the conical rubber wheel 22 completes the guiding and positioning of the bus duct shell 1, the cylinder 24 is started, and the piston rod of the cylinder 24 extends to push the connecting push plate 25. The connecting push plate 25 drives the top blocks 26 on both sides to move synchronously toward the shell 1. The anti-slip gasket 27 on the top block 26 is in close contact with the surface of the shell 1, forming a rigid clamping force, which effectively prevents the shell 1 from moving due to vibration and other factors during the cutting process, thereby ensuring cutting accuracy.

[0067] In order to elastically limit the movement of the top plate 33 and ensure that the top plate 33 can be reset in time after each cutting of the shell 1 is completed, the following features are specifically provided:

[0068] Two plate seats 34 (such as Figure 3 As shown), both ends of the top plate 33 are fixedly connected with positioning pins 35 that are slidably connected to the plate seat 34;

[0069] A positioning spring 36 is sleeved on the outside of each positioning pin 35 , one end of the positioning spring 36 is fixedly connected to the plate seat 34 , and the other end is fixedly connected to the top plate 33 . After being pushed by the end of the shell 1 , the top plate 33 abuts against the output end of the touch pressure sensor 37 .

[0070] As the housing 1 is pushed along the workbench 2, the end of the housing 1 pushes the top plate 33, which slides along the positioning pin 35 and compresses the positioning spring 36 until the top plate 33 contacts and triggers the touch pressure sensor 37. After cutting is completed, when the housing 1 and the top plate 33 are separated, the elastic force of the positioning spring 36 automatically resets the top plate 33 to its initial position, waiting for the next feeding trigger.

[0071] In order to supply gas to the air pipe 51 and improve the uniformity of the gas ejected from the air pipe 51, and ensure that the debris generated during the cutting process of the shell 1 can be blown into the perforation 3, the following features are specifically provided:

[0072] The anti-splash mechanism 38 further includes two air pumps 52 fixedly connected to the side wall of the workbench 2, and the output end of the air pump 52 is connected to the air pipe 51 through a hose (such as Figure 4 As shown, the air pipe 51 is fixedly connected with air nozzles 53 at equal intervals along the axial direction (as shown in FIG. Figure 5 As the cutting operation progresses, the air pump 52 starts and supplies air to the air pipe 51 through a hose. Air is ejected from nozzles 53 evenly distributed on the air pipe 51, forming a directional airflow in the cutting area. This airflow blows the debris generated during the cutting process toward the perforations 3 of the workbench 2, preventing debris from scattering, maintaining a clean work environment, and preventing debris accumulation that could affect equipment operation.

[0073] In order to realize that when the top baffle 42 deflects toward the direction of the electric saw 9, the two auxiliary baffles 49 can also move toward the direction of the electric saw 9, thereby providing multi-angle protection for the electric saw 9 in the working state, the following features are specifically provided:

[0074] The anti-splash mechanism 38 further includes a dual-axis motor 48 fixedly connected to the main baffle 39, and the two output ends of the dual-axis motor 48 are respectively fixedly connected to the main pulley 47 (such as Figure 5 As shown in the figure, a power pulley 46 is rotatably provided beside the main pulley 47. The power pulley 46 is connected to the main pulley 47 through a belt. The power pulley 46 is coaxially connected to the power gear 44. The upper end of the auxiliary baffle 49 is fixedly connected to the power rack 45. The power rack 45 is meshed with the power gear 44.

[0075] Deflection gears 43 are fixedly connected to both sides of one end of the top baffle 42 close to the main baffle 39 , and the deflection gears 43 are meshed with corresponding power gears 44 .

[0076] After the dual-axis motor 48 is started, the two output ends of the dual-axis motor 48 drive the main pulley 47 to rotate, and the main pulley 47 drives the power pulley 46 to rotate through the belt transmission. The power gear 44 on the power pulley 46 drives the power rack 45 on the auxiliary baffle 49 to move, and then the auxiliary baffle 49 moves in the direction close to the electric saw 9 (as shown in FIG. Figure 4 At the same time, the power gear 44 engages with the deflection gear 43 of the top baffle 42, causing the top baffle 42 to deflect toward the power saw 9. The main baffle 39, auxiliary baffle 49, and top baffle 42 work together to form a semi-enclosed splash-proof area, protecting the power saw 9 from multiple angles.

[0077] In order to facilitate the operator to observe the shell 1 being cut, and also to prevent the debris generated during the cutting process from flying around, the following features are specifically set:

[0078] An observation window 40 (such as Figure 4 As shown), a transparent member 41 is fixedly connected to the observation window 40;

[0079] A fire curtain 50 is fixedly connected to the lower end of the auxiliary baffle 49 .

[0080] During the cutting process, the operator can clearly observe the cutting progress of the shell 1 through the transparent member 41 in the observation window 40 of the main baffle 39, facilitating timely parameter adjustments. The fire curtain 50 at the lower end of the auxiliary baffle 49 hangs down to the surface of the workbench 2, effectively blocking sparks and debris generated during the cutting process, preventing them from splashing outside the work area and ensuring operational safety.

[0081] In order to collect debris in a centralized manner, the following features are also set:

[0082] A baffle plate 6 (such as Figure 4 shown);

[0083] The lower end of the through hole 3 is fixedly connected with an oblique material introducing cover 4 , and the lower end of the oblique material introducing cover 4 is provided with a collecting hopper 5 .

[0084] When the airflow from the air nozzle 53 blows the debris toward the through-hole 3, the material baffle 6 guides and blocks the debris, ensuring that the debris falls smoothly into the through-hole 3. The oblique guide cover 4 below the through-hole 3 collects the debris and guides it into the collection hopper 5, achieving centralized collection of the debris, facilitating subsequent cleaning, and keeping the workbench 2 and the surrounding environment clean.

[0085] The detailed working principle of this device is as follows: When the busbar trunking housing 1 needs to be cut, the operator pushes the housing 1 along the workbench 2. During the pushing process, the auxiliary motor 31 drives the bidirectional screw 30 to rotate according to the pre-set width information of the housing 1, driving the two curved frames 17 to move synchronously closer or farther away via the slide 28, so that the relatively arranged conical rubber wheels 22 are adjusted to the appropriate spacing, ensuring that the two sides of the housing 1 can be stably pressed against the conical rubber wheels 22. The main motor 12 is then started, and through the transmission of the main shaft 13, sleeve 15, primary bevel gear 18 and secondary bevel gear 19, it drives the conical rubber wheels 22 to rotate, playing a guiding role during the pushing process of the housing 1, ensuring that the housing 1 moves smoothly along a straight line.

[0086] When the end of the housing 1 pushes against the top plate 33, compressing the positioning spring 36 and triggering the pressure sensor 37, the sensor transmits a signal to the controller. The controller then activates the air cylinder 24, which, through the engaging push plate 25, pushes the top block 26. The anti-slip pad 27 rigidly clamps the housing 1 to prevent displacement during cutting. Simultaneously, the pneumatic slide 10 drives the electric saw 9 to the cutting position. The dual-axis motor 48 drives the main baffle 39, auxiliary baffle 49, and top baffle 42 to form a semi-enclosed splash-proof area. The fire curtain 50 at the lower end of the auxiliary baffle 49 droops to the surface of the workbench 2 to prevent sparks and debris from flying.

[0087] After the cutting operation begins, the air pump 52 is started, and air is sprayed toward the cutting area through the air pipe 51 and the air nozzle 53, blowing the generated debris toward the perforation 3. Under the guidance of the baffle plate 6, the debris falls into the oblique material guide hood 4 through the perforation 3 and finally gathers in the collecting hopper 5. The operator can monitor the cutting situation in real time through the transparent part 41 in the observation window 40 of the main baffle 39. After the cutting is completed, the pneumatic slide 10 drives the electric saw 9 to reset, the cylinder 24 retracts the top block 26, the auxiliary motor 31 reverses to reset the curved frame 17, and the positioning spring 36 pushes the top plate 33 back to the initial position, waiting for the next loading. The entire process realizes the full-process automation of the bus duct shell 1 from automatic guiding positioning, clamping and fixing, cutting protection to debris collection, effectively improving the processing efficiency and quality.
