Description

[0002] Various parts used for replacement and maintenance in construction machinery, production equipment, and transportation equipment are called mechanical accessories. Among them is a metal accessory with a V-groove used for splicing and sealing.

[0003] When processing this type of metal accessory, in order to cut out the V-groove, it is necessary to frequently adjust the direction of the metal sheet during cutting. In addition, in order to ensure the sealing effect of the splicing, the bevels of the V-groove are all inclined structures, which creates difficulties for the cutting process. While adjusting the direction of the metal sheet, it is also necessary to adjust the angle of the metal sheet. After the adjustment, in order to ensure the cutting stability, the metal sheet needs to be fixed, which increases a lot of workload. Frequent adjustments of direction and angle will also increase the error of metal accessory processing, which is not conducive to improving the quality of the finished metal accessories.

Two first rails 5 are symmetrically installed on one side of the top of the operating table 1. The tops of the two first rails 5 are slidably connected to first electric sliders 6. Second rails 7 are fixedly installed on the tops of the two first electric sliders 6. A conveying mechanism 8 including a second electric slider 9 is slidably provided on the tops of the second rails 7. A mounting frame 17 is fixedly installed on the top of the operating table 1. A rotating shaft 18 is rotatably installed on the top of the mounting frame 17. A rotating frame 19 is fixedly connected to the top of the rotating shaft 18. A steering knuckle 20 is installed at the end of the rotating frame 19. A mounting plate 21 is fixedly connected to the end of the steering knuckle 20. A rotating disc cutter 22 is fixedly installed on the side wall of the mounting plate 21. An adjustment mechanism 23 including a fixing ring 24 is provided on the side of the mounting plate 21 close to the rotating frame 19. The metal plate 2 is a long strip structure, and the metal fitting 3 is made by cutting a V-shaped groove 4 on one side of the metal plate 2; A second electric slider 9 is slidably connected to the top of one side of the second track 7. First sliding grooves 11 are symmetrically opened on both sides of the top of the second electric slider 9. First sliders 12 are slidably connected in the first sliding grooves 11. Clamping blocks 13 are fixedly connected to the tops of the two first sliders 12. Annular grooves 26 are provided at the top and bottom of the side wall of the rotating frame 19 on the side close to the mounting plate 21. Fixed rings 24 that are slidably connected to the two annular grooves 26 are fixedly connected to the top and bottom of the side wall of the mounting plate 21 on the side close to the rotating frame 19. A mounting groove 27 is provided in the middle of the rotating frame 19 on one side of the annular groove 26. The end of the mounting groove 27 is rotatably connected to the first electric cylinder 25. The telescopic end of the first electric cylinder 25 is rotatably connected to the side wall of the mounting plate 21. The first electric slider 6 is used to adjust the position of the second rail 7 to facilitate the conveying mechanism 8 to adjust the conveying position of the metal plate 2, so as to facilitate the processing of metal plates 2 of different sizes. The conveying mechanism 8 clamps and conveys the metal plate 2 through the second electric slider 9, so that the metal plate 2 can be easily moved to the cutting position below the rotating disc cutter 22 after being fixed, and the metal plate 2 can be conveyed in combination with the rotation angle of the rotating disc cutter 22, so that the process of cutting the metal plate 2 into metal accessories 3 is smooth. The clamping block 13 can be flexibly moved to center and The metal plate 2 is fixed by the clamping mechanism, thereby improving the cutting accuracy of the metal plate 2 and being adaptable to metal plates 2 of different widths. The rotary disc cutter 22 is connected to the rotary frame 19 through the steering knuckle 20, and the cutting angle of the rotary disc cutter 22 can be adjusted by the adjusting mechanism 23, so that the rotary disc cutter 22 can cut a V-shaped edge on the metal plate 2. At the same time, the rotary frame 19 is rotated by the push of the second electric cylinder 28 to push the rotary disc cutter 22 down, so that the angle of the rotary disc cutter 22 itself is tilted, and an oblique angle can be generated when cutting the metal plate 2, so that a V-shaped edge can be cut. Figure 2The V-groove 4 of the beveled cut can improve the sealing effect during splicing. The beveled cut can be directly cut out by combining the adjustment mechanism 23 and the second electric cylinder 28, without the need to frequently adjust the position and angle of the metal plate 2 as in the traditional way. This can save processing time and reduce the error of the metal accessories 3.

The second electric slide 9 and the third electric slide 16 have the same structure. The third electric slide 16 is also used to clamp the metal plate 2, preventing one end of the metal plate 2 from shaking during cutting and affecting normal operation. When processing smaller metal plates 2, the movement of the third electric slide 16 and the synchronous movement of the second electric slide 9 can facilitate the transportation of the metal plate 2.

[0023] As a technical optimization solution of the present invention, a pressure block is fixedly connected to the top of the clamping block 13, and a bidirectional screw 14 is rotatably connected to the middle of the second electric slider 9.

The first motor 15 drives the bidirectional screw 14 to rotate, thereby driving the first slider 12 and the clamping block 13 to move closer to each other to clamp or away from each other to release the metal plate 2. The pressure block can press the top of the metal plate 2 when the clamping block 13 clamps the metal plate 2, preventing the metal plate 2 from shaking when being cut by the rotating disc cutter 22.

[0024] As a technical optimization solution of the present invention, a bracket is fixedly connected to the bottom of the end of the rotating frame 19 away from the rotating disc 22. The end of the bracket is rotatably connected to the telescopic end of a second electric cylinder 28. The fixed end of the second electric cylinder 28 is rotatably connected to the side wall of the workbench 1. The extension of the telescopic end of the second electric cylinder 28 drives the rotating frame 19 to rotate, driving the rotating disc 22 downward to cut the metal plate 2. Conversely, the extension of the telescopic end of the second electric cylinder 28 causes the rotating frame 19 to rotate and move the rotating disc 22 downward to cut the metal plate 2.

After the V-groove 4 is cut into the metal plate 2, when the metal fitting 3 is cut, the extension frame 31 is rotated to the bottom of the metal fitting 3 and the clamping plate 34 is used to clamp the metal fitting 3. After the metal fitting 3 is cut, it can be directly compressed by the extension frame 31 and the clamping plate 34 and rotated to the support plate 38 for inspection and classification. This allows the cutting process and quality inspection of the metal fitting 3 to be linked through the extension frame 31, eliminating the need for unified inspection after the entire metal plate 2 is processed into the metal fitting 3, saving labor time and improving equipment utilization.

[0027] As a technical optimization of the present invention, a fourth electric cylinder 35 is fixedly mounted on the top of the extension frame 31. This fourth electric cylinder 35 is electrically connected to an external controller. The telescopic end of the fourth electric cylinder 35 extends through the bottom of the inverted L-shaped plate 32, and a push plate 36 is fixedly connected to the distal end of the telescopic end of the fourth electric cylinder 35. The fourth electric cylinder 35 is linked to the inspection mechanism 44. When the inspection mechanism 44 detects that the metal fitting 3 is qualified, the telescopic end of the fourth electric cylinder 35 is controlled to extend, causing the push plate 36 to push the qualified metal fitting 3 onto the belt conveyor 40 for transportation to the next workstation.

[0028] As a technical optimization solution of the present invention, a portal frame 37 is fixedly mounted on the top of the operating table 1 on the side of the fixed seat 29 away from the rotating disc cutter 22. A support plate 38 is fixedly connected to the middle of the portal frame 37 at the same level as the extension frame 31. A waste chute 39 is fixedly mounted on the portal frame 37 on the side of the support plate 38. A belt conveyor 40 is mounted on the top of the operating table 1 on the side of the support plate 38 away from the fixed seat 29 at the same level as the extension frame 31. The support plate 38 is used to support the cut metal parts 3 to facilitate subsequent inspection of the metal parts 3. The waste chute 39 is used to receive metal parts 3 that fail inspection.

The detection mechanism 44 detects the slope of the V-shaped groove 4 through the triangular block 45 accessing the V-shaped groove 4, after the triangular block 45 accesses the V-shaped groove 4, the four slide rods 46 are extruded by the V-shaped groove 4 and slide to the inside of the triangular block 45, and finally the ends of the slide rods 46 abut against the contact switches 47, so that the contact switches 47 generate four contact signals, it can be judged that the slope of the V-shaped groove 4 meets the standard, the contact switches 47 transmit signals to the external controller, the external controller controls the telescopic end of the third electric cylinder 33 and the fifth electric cylinder 43 to retract, and then controls the telescopic end of the fourth electric cylinder 35 to extend, so that the push plate 36 pushes the qualified metal fittings 3 to move to the belt conveyor 40 and is conveyed to the next station, if the slope of the V-shaped groove 4 is too large or too small, then the bottom or top between the triangular block 45 and the V-shaped groove 4 will inevitably have a gap, at this time, under the action of the springs 48, the slide rods 46 at the bottom or top will be forced to slide out of the triangular block 45 and be separated from the contact switches 47, that is, the contact switches 47 lose part of the contact signals, that is, it can be judged that the slope of the V-shaped groove 4 is unqualified, the contact switches 47 transmit signals to the external controller, the external controller controls the telescopic end of the third electric cylinder 33 to retract, and then controls the fourth electric sliding block 42 to drive the fifth electric cylinder 43, the triangular block 45 and the unqualified metal fittings 3 to slide along the fourth sliding groove to the direction of the waste groove 39, until the unqualified metal fittings 3 fall into the waste groove 39 for recycling, at the same time, the external controller controls the on-site console to issue a signal to remind the staff to timely adjust the equipment precision, through the detection of the slope of the V-shaped groove 4, the machining precision of the metal fittings 3 can be determined in time, the unqualified metal fittings 3 are prevented from flowing into the next process, when unqualified products are found, the staff can be prompted to timely adjust the equipment, to prevent the subsequent production of unqualified products again, which is conducive to improving the cutting precision and quality of the metal fittings 3, and has a positive significance for improving the production efficiency.

[0030] When the present invention is in use, the third electric slider 16 is controlled to slide along the second track 7 to a point away from one end of the second electric slider 9, the metal plate 2 is placed on the top of the second electric slider 9 and the third electric slider 16, and one end of the metal plate 2 is abutted against the side wall of the limit plate 10, while the other end of the metal plate 2 is located below the rotating disc cutter 22. At this time, the two first motors 15 are controlled to rotate, and the two first motors 15 drive the two bidirectional screws 14 to rotate so that the two groups of first sliders 12 bring the two groups of clamping blocks 13 closer to each other along the first slide groove 11 until the two groups of clamping blocks 13 respectively clamp the two sides of the metal plate 2. At this time, the pressure block on the top of the clamping block 13 abuts against the top of the metal plate 2, and the telescopic end of the first electric cylinder 25 is controlled to extend, pushing the mounting plate 21 and the rotating disc cutter 22 to rotate around the steering knuckle 20 as shown in the figure. Figure 15 When the mounting plate 21 is rotated, the fixing ring 24 rotates along the annular groove 26, the rotary disc cutter 22 is started, the telescopic end of the second electric cylinder 28 is controlled to extend, and the rotating frame 19 and the rotary disc cutter 22 are pushed to rotate around the rotating shaft 18, so that the rotary disc cutter 22 descends. Since the rotary disc cutter 22 rotates to the angle a at the same time and descends in the height position, the rotary disc cutter 22 generates a bevel angle when cutting the metal plate 2, and a bevel cut can be cut.

[0031] After the cutting is completed, the telescopic end of the second electric cylinder 28 is controlled to retract, driving the rotating frame 19 and the rotating disc 22 to rotate around the rotating shaft 18 so that the rotating disc 22 rises. At the same time, the telescopic end of the first electric cylinder 25 is controlled to retract, driving the mounting plate 21 and the rotating disc 22 to return to the direction parallel to the rotating frame 19 (i.e., Figure 15 c), after which the first motor 15 on the third electric slider 16 is reversed so that the bidirectional screw 14 drives the two first sliders 12 and the clamping block 13 to slide oppositely along the first slide groove 11 until the clamping block 13 and the pressure block are separated from the metal plate 2, and the second electric slider 9 is controlled to slide a certain distance along the second track 7 toward the rotating disc cutter 22, so that the metal plate 2 can slide synchronously. After reaching the position, the first motor 15 on the third electric slider 16 rotates to drive the clamping block 13 to clamp the two sides of the metal plate 2 again, and the telescopic end of the first electric cylinder 25 is controlled to continue to retract, driving the mounting plate 21 and the rotating disc cutter 22 to rotate around the steering knuckle 20 to the position as shown in FIG. Figure 15 At the angle position b, the rotary disc cutter 22 is started, the telescopic end of the second electric cylinder 28 is controlled to extend, and the rotating frame 19 and the rotary disc cutter 22 are pushed to rotate around the rotating shaft 18, so that the rotary disc cutter 22 descends, and the same bevel cut is cut, and it is connected with the first bevel cut to form a V-shaped groove 4.

[0032] After the cutting is in place, the telescopic end of the second electric cylinder 28 is controlled to retract, so that the rotary disc cutter 22 rises, and at the same time, the telescopic end of the first electric cylinder 25 is controlled to extend, driving the rotary disc cutter 22 to return to the position as shown in FIG. Figure 15At the angle position c, the rotating disc cutter 22 is facing the cutting position of the metal plate 2. At this time, the rotating table 30 is controlled to drive the extension frame 31 to rotate around the fixed seat 29 so that the top end of the extension frame 31 rotates to the bottom of the end of the metal plate 2 where the V-shaped groove 4 is cut. The third electric cylinder 33 is started to push the clamping plate 34 down to press the top of the metal plate 2. The rotating disc cutter 22 is started, and the telescopic end of the second electric cylinder 28 is controlled to extend, pushing the rotating frame 19 and the rotating disc cutter 22 to rotate around the rotating shaft 18 so that the rotating disc cutter 22 descends to cut the metal plate 2. After cutting, it is processed into a metal accessory 3, and the cut metal accessory 3 is clamped by the clamping plate 34 and the extension frame 31.

[0033] If the length and width of the processed metal accessories 3 and the slope of the V-groove 4 are changed, the processing position and size can be adjusted by controlling the extension length of the first electric cylinder 25 to change the rotation angle of the rotating disc cutter 22 and controlling the first electric slider 6 to drive the second track 7 to move along the first track 5.

[0034] The rotating platform 30 is controlled to drive the extension frame 31 to rotate around the fixed seat 29 so that the extension frame 31 and the metal fitting 3 rotate 90 degrees to the top of the support plate 38. At this time, the inclination of the V-shaped groove 4 is detected, and the telescopic end of the fifth electric cylinder 43 is controlled to extend to push the triangular block 45 down and finally enter the V-shaped groove 4. At this time, the four sliding rods 46 are squeezed by the V-shaped groove 4 and slide to the inside of the triangular block 45. Finally, the end of the sliding rod 46 abuts the contact switch 47, so that the contact switch 47 generates four contact signals and compresses each spring 48. At this time, it can be judged that the inclination of the V-shaped groove 4 meets the standard. The contact switch 47 transmits the signal to the external controller, and the external controller controls the telescopic end of the third electric cylinder 33 to retract, so that the pressing plate 34 is separated from the metal fitting 3. At the same time, the telescopic end of the fifth electric cylinder 43 is controlled to retract to drive the triangular block 45 to separate from the V-shaped groove 4. The telescopic end of the fourth electric cylinder 35 is controlled to extend, so that the push plate 36 pushes the qualified metal fitting 3 to move to the belt conveyor 40 for transportation to the next process If the slope of the V-groove 4 is too large or too small, after the triangular block 45 is connected to the V-groove 4, a gap will inevitably be generated at the bottom or top between the triangular block 45 and the V-groove 4. At this time, under the action of the spring 48, the bottom or top sliding bar 46 will be forced to slide out of the triangular block 45 and disengage from the contact switch 47, that is, the contact switch 47 loses part of the contact signal, and it can be judged that the slope of the V-groove 4 is unqualified. The contact switch 47 transmits the signal to the external controller, and the external controller controls the telescopic end of the third electric cylinder 33 to retract, so that the clamping plate 34 is separated from the metal fitting 3, and then controls the fourth electric slide 42 to drive the fifth electric cylinder 43, the triangular block 45 and the unqualified metal fitting 3 to slide along the fourth slide toward the waste trough 39. After the unqualified metal fitting 3 falls into the waste trough 39, the fourth electric slide 42 drives the fifth electric cylinder 43 and the triangular block 45 to reset. At the same time, the external controller controls the on-site console to send a signal to remind the staff to make timely adjustments to the equipment accuracy.

[0035] By repeating the above steps, a series of operations including cutting of the metal plate 2, clamping and testing of the metal fittings 3, conveying of qualified products and recycling of unqualified products are achieved.
