Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of composite material cutting, and particularly relates to a high-precision numerical control cutting mechanism special for glass fiber composite materials. BACKGROUND

[0002] Glass fiber composite material (GFRP) is widely used in the fields of aerospace and new energy vehicles as a lightweight structure core material. The cutting quality directly affects the fatigue strength and assembly precision of components, especially the edge burr amount and length tolerance. However, the existing cutting equipment still has some defects in use, specifically:

[0003] Firstly, when the existing device cuts, the cutting edge of the tool extrudes the resin matrix, causing the glass fiber to be pulled out before being cut off, forming a "whisk" burr defect, and multiple polishing is required after cutting for use.

[0004] Secondly, the traditional equipment relies on the indirect calculation of length by the feed roller encoder, and the friction coefficient between the roll material and the driving roller fluctuates, causing the actual feeding length to be less than the encoder count, which easily leads to different storage amounts of each group of rolls, affecting the average degree.

In addition, the three-dimensional spatial dimensions of length, width and depth should be included in the actual manufacture.

[0048] Please refer to the accompanying drawings Figures 1 to 3 , Figures 7 to 8 , Figure 14 As shown in the drawings, the embodiment provides a high-precision numerical control cutting mechanism special for glass fiber composite materials, which comprises:

[0049] A workbench 10 is provided, and a shielding cover 11 is installed on the workbench 10. A support 12 and a support 13 are respectively installed on the left side and the right side of the upper end of the workbench 10. A receiving disc 15 is installed on the support 13.

[0050] A driving assembly 20 is provided, and the driving assembly 20 comprises a conveying roller 21. The conveying roller 21 is arranged on the support 12, and a counter 24 is connected to the lower end of the conveying roller 21.

[0051] A control assembly 30 is arranged on the inner cavity of the shielding cover 11.

[0052] A cutting assembly 40 is provided, and the cutting assembly 40 comprises an additional frame 41. A blade 43 and a heating disc 44 are installed in the inner cavity of the additional frame 41.

[0053] A stabilizing assembly 50 is provided, and the stabilizing assembly 50 comprises a lifting frame 53. The lifting frame 53 is arranged on the upper end of the workbench 10, and a receiving disc 15 is also arranged on the lifting frame 53.

[0054] A detection assembly 60 is provided, and the detection assembly 60 comprises an arc-shaped frame 62. A sliding frame 65 is arranged on the lower end of the arc-shaped frame 62, and a switch 66 is arranged on the sliding frame 65.

[0055] The receiving disc 15 is used for placing the winding disc, the counter 24 is used for recording the length of the conveying roller 21, and the arc-shaped frame 62 is in contact with the outside of the winding disc. When the diameter of the winding disc reaches the set value, the arc-shaped frame 62 is pushed to contact the switch 66.

[0056] It should be noted that the front of the isolation cover 11 is hinged with a box door, which is convenient for maintaining the internal device;

[0057] The box door of the isolation cover 11 is made of transparent material, which is convenient for observing the processing condition inside.

[0058] In this embodiment, when in use, the winding disc for receiving the composite material is placed on the receiving disc 15, then the lifting frame 53 is pulled up, and the receiving disc 15 on the lifting frame 53 is inserted into the other end of the winding disc, then the winding disc is connected with the composite material, the conveying roller 21 runs to convey the material, and the length of the conveying is recorded by the counter 24. At the same time, the arc-shaped frame 62 is also attached to the inside of the winding disc, and gradually moves to the right side with the receiving of the composite material, until the counter 24 records the appropriate number, and the arc-shaped frame 62 also touches the switch 66, indicating that the receiving length has reached the appropriate number. At this time, the regulating assembly 30 operates to fix the two ends of the composite material, and the regulating assembly 30 drives the blade 43 to approach the material, then the heating disc 44 operates to heat the blade 43, and the blade 43 after being heated is used to cut the material, which produces a slight heat melting phenomenon on the cutting surface of the material, thereby reducing the generation of burrs.

[0059] Secondly, please refer again to Figures 1 to 3 , Figure 12 The motor one 14 is fixedly installed on the upper end of the rear side of the support two 13, the output shaft of the motor one 14 is fixedly connected with the rotating shaft of the receiving disc 15, and the shaft center of the receiving disc 15 is provided with two groups of air slots, and the two groups of air slots are slidably connected with the protrusions 16. The middle part of the one end of the two groups of protrusions 16 extending out of the inner cavity of the receiving disc 15 is fixedly connected with the spring one 17, and the other end of the spring one 17 is fixedly connected in the middle part of the inner cavity of the receiving disc 15. The workbench 10 is provided with a discharging groove 18 at the position of the lower end of the middle part of the isolation cover 11.

[0060] It should be noted that the upper end of the protrusion 16 is provided with a slope, and the bottom end of the slope is close to the outside of the receiving disc 15, which is designed to enable the protrusion 16 to be squeezed into the groove in the inner ring of the winding disc for fitting and fixing when installing winding discs of different sizes, avoiding the inability to install winding discs of different sizes.

[0061] The lower end of the protrusion 16 is fixedly connected with two limiting strips, which is designed to limit the movement range of the protrusion 16, avoiding the protrusion 16 from affecting the use by completely extending out of the receiving disc 15.

[0062] Preferably, to ensure normal operation of the device, a device for receiving waste materials should be placed below the discharge chute 18 to avoid the spread of waste materials affecting the surrounding environment.

[0063] In this embodiment, the winding disc for receiving the composite material is placed on the receiving disc 15 when in use, and the groove in the inner circle of the winding disc will press the convex strip 16, causing the convex strip 16 to shrink into the empty slot of the receiving disc 15. When the winding disc is completely placed, the spring 17 pushes the convex strip 16 to rebound and is clamped in the groove in the inner circle of the winding disc, thereby fixing different models of winding discs and preventing the winding disc from shifting when receiving the material. Subsequently, the motor 14 drives the receiving disc 15 to rotate, and the receiving work of the composite material is performed.

[0064] Secondly, please refer to Figures 3 to 4 , the conveying rollers 21 are arranged in two groups and are distributed above and below the middle part of the inner cavity of the support 12, the driving assembly 20 further includes the gear 22, the rear ends of the two groups of conveying rollers 21 are fixedly connected with the gear 22 penetrating through the support 12, the outer circles of the two groups of gears 22 are meshed with each other, the motor 23 is fixedly installed on the upper end of the rear side of the support 12, and the output shaft of the motor 23 is fixedly connected with the center of the gear 22 located on the upper side;

[0065] The driving assembly 20 further includes the gear 25, the gear 25 is fixedly connected with the rotating shaft of the counter 24, and the gear 26 is fixedly connected with the axis of the gear 22 located on the lower side, the outer circle of the gear 26 is meshed with the chain 27, and the inner circle of the lower end of the chain 27 is meshed with the outer circle of the gear 25.

[0066] It should be noted that the outer circle of the conveying roller 21 is provided with a rubber anti-skid pad, and the distance between the two groups of conveying rollers 21 should be less than 1 mm, which aims to convey the composite material by using the conveying roller 21 and enhance the friction and elasticity by using the rubber anti-skid pad, so as to cope with composite materials of different thicknesses.

[0067] The outer diameter of the gear 25 is the same as that of the gear 26, which aims to make the rotating speed and the number of turns of the counter 24 the same as the rotating speed of the conveying roller 21.

[0068] The counter 24 is a device for judging the conveying length of the composite material by counting the number of turns of the gear 25, and the accuracy of the calculation is improved by using the anti-skid pad of the outer circle of the conveying roller 21, so as to reduce the occurrence of the composite material slipping, pulling and transverse moving.

[0069] Preferably, to ensure the extension of the service life of the device, protective shells can be installed on the outer circles of the gears and the chain 27 to isolate them, so as to prevent the glass fibers from falling into the gaps of the structures and affecting the use.

[0070] In this embodiment, in use, the motor 23 drives the upper gear 22 to rotate, and drives the lower gear 22 to rotate synchronously, at this time, the two sets of conveying rollers 21 rotate with the two sets of gears 22, and the lower gear 22 drives the gear 26 to rotate, the gear 26 drives the gear 25 to rotate through the chain 27, and the counter 24 rotates with the conveying rollers 21, and records the number of rotations, and the length of the composite material conveyed by the conveying rollers 21 can be obtained by calculating the number of rotations.

[0071] Secondly, referring again to Figures 5 to 7 , the control assembly 30 further comprises two sets of extrusion frames 31, which are respectively installed on the left and right sides of the lower end of the inner cavity of the isolation cover 11, and the inner cavities of the two sets of extrusion frames 31 are slidingly connected with lifting blocks 32, the middle parts of the two sets of lifting blocks 32 and the middle parts of the extrusion frames 31 are fixedly connected with extrusion rollers 33, and the two sets of extrusion rollers 33 are distributed above and below, the inner cavity of the isolation cover 11 is fixedly installed with an electric guide rail 34, a sliding block in the inner cavity of the electric guide rail 34 is fixedly installed with an electric push rod 35, and the lower end of the electric push rod 35 is fixedly connected with an assembly plate 36.

[0072] It should be noted that the inner cavity of the extrusion frame 31 is provided with a pneumatic telescopic rod (as shown in Figure 5 ), which is used to drive the lifting block 32 to lift and lower, and control devices should be arranged in series between the front and rear two sets of extrusion frames 31 to ensure that the two sets of lifting blocks 32 can lift and lower synchronously;

[0073] The electric guide rail 34 is an electric drive sliding rail, which is used to adjust the position of the electric push rod 35;

[0074] The outer ring of the extrusion roller 33 is provided with a pad of anti-slip material, which is used to fix the composite material by the extrusion roller 33, so as to avoid slipping or deviation of the composite material during cutting, causing damage to the material during cutting, affecting the use effect, and also fixing the composite material to reduce the situation of slipping and deviation of the material in the conveying roller 21, improving the accuracy;

[0075] In use, the left extrusion roller 33 can be driven to clamp and fix the material first, and then the right extrusion roller 33 can be driven to fix the material after the material is pulled tight by the rotation of the motor 14, so as to improve the tightness of the material during cutting and improve the flatness of cutting.

[0076] In this embodiment, after the material is conveyed, the pressing frame 31 drives the lifting block 32 to lower the pressing roller 33, clamps and fixes the composite material, at this time, the electric guide rail 34 drives the electric push rod 35 to move the assembly plate 36 until the blade 43 is above the composite material, then the electric push rod 35 drives the blade 43 to approach the material. After cutting is completed, the electric guide rail 34 drives the electric push rod 35 to reset, releasing the fixation of the composite material, then the motor 14 drives the storage disc 15 to continue rotating, and the next round of composite material storage work is carried out.

[0077] Please refer again to Figures 5 to 7 The mounting frame 41 is installed at the lower middle part of the assembly plate 36, and the cutting assembly 40 further comprises a control component 42, which is installed at the left middle part of the mounting frame 41, and the output shaft of the control component 42 is fixedly connected with the rotating shaft of the blade 43.

[0078] The cutting assembly 40 further comprises an air pipe 45, which is fixedly connected at the middle part of the assembly plate 36, and the upper end of the air pipe 45 extends out of the isolation cover 11 and is fixedly connected at the left upper end of the isolation cover 11. The lower end of the air pipe 45 is provided with two groups of air inlets, and each of the two groups of air inlets is communicated with an adsorption cover 46.

[0079] It should be noted that the control component 42 is a component for driving the blade 43 to operate and controlling the use of the heating disc 44;

[0080] The heating disc 44 is an electric heating assembly with an electric heating wire built-in;

[0081] The temperature range of the heating disc 44 during operation should be controlled between 100℃ and 120℃, which aims to heat the blade 43 by using the heating disc 44, so that a slight hot melting phenomenon can be formed on the surface of the material during cutting, reducing the burr of the cutting surface of the composite material;

[0082] The adsorption cover 46 is provided with two groups, and the inlet of each of the two groups of adsorption covers 46 faces the lower end of the blade 43, which aims to adsorb the debris generated during cutting by using the adsorption cover 46;

[0083] The air pipe 45 is a relatively hard hose, which aims to follow the movement of the assembly plate 36, avoid damage, and use the relatively hard material of the air pipe 45 to avoid the inner wall bending and fitting, affecting the dust collection effect.

[0084] Preferably, the device needs to be connected with a dust collection component such as an air pump during use, and the component is communicated with the air pipe 45 (this is a common technical structure in the prior art, but more description is not given), so that the dust collection component can adsorb the debris generated during cutting through the air pipe 45 and the adsorption cover 46.

[0085] In this embodiment, when cutting, the heating disc 44 preheats the blade 43, and when the temperature of the blade 43 reaches a preset range, the control component 42 drives the blade 43 to rotate, thereby cutting the composite material below. At this time, the external air pump sends negative pressure to the suction cover 46 through the air pipe 45, so that the suction cover 46 generates suction force to suck the debris generated during cutting, avoiding the debris flying everywhere and affecting the working environment. The heated blade 43 will cause slight heat melting phenomenon on the cutting surface of the material during cutting, so that the fibers on the cutting surface are fused and adhered, thereby reducing the generation of burrs and improving the flatness of the cutting surface.

[0086] Please refer again to Figures 8 to 12 The stable assembly 50 further comprises a sliding groove 51, which is arranged at the upper right side of the workbench 10, and the inner cavity of the sliding groove 51 is slidably connected with a moving block 52. The lifting frame 53 is slidably connected in the moving block 52. The inner cavity of the moving block 52 is slidably connected with a positioning pin 54, and the middle segment outer circle of the positioning pin 54 is movably inserted into the lower middle part of the lifting frame 53.

[0087] The stable assembly 50 further comprises a sliding block 55, which is slidably connected to the upper end of the lifting frame 53. Another set of storage discs 15 are rotatably connected to the side of the sliding block 55 close to the support 2 13 through a ball bearing. A plurality of insertion grooves 56 are arranged on the upper end of the sliding block 55. The upper end of the lifting frame 53 is slidably connected with an insertion rod 57, and the lower end of the insertion rod 57 is movably inserted into one of the insertion grooves 56. The middle part of the two sides of the insertion rod 57 is fixedly connected with a spring 2 58, and the upper end of the spring 2 58 is fixedly connected to the inner cavity of the upper end of the lifting frame 53. The side of the sliding block 55 away from the support 2 13 is fixedly connected with a handle 59.

[0088] It should be noted that the moving block 52 is a cross-shaped block, which is designed to allow the moving block 52 to slide in the sliding groove 51 and prevent the moving block 52 from coming off the sliding groove 51.

[0089] In order to ensure that the moving block 52 can be fixed at different positions, a locking assembly should be installed on the moving block 52, such as a manual guide rail lock and a clamp.

[0090] The length of the storage disc 15 on the sliding block 55 should be less than that of the storage disc 15 on the support 2 13, which is designed to use the two sets of storage discs 15 to limit the two ends of the winding disc and improve the stability of the limiting disc when rolling.

[0091] The upper end of the lifting frame 53 and the upper end of the insertion rod 57 should be provided with a handle, which is designed to facilitate the lifting of the lifting frame 53 and the insertion rod 57.

[0092] In this embodiment, the moving block 52 is pushed to make the lifting frame 53 close to the other end of the winding disc, then the lifting frame 53 is pulled up until the receiving disc 15 on the lifting frame 53 is in contact with the other end of the winding disc, at this time the positioning pin 54 is inserted into the lifting frame 53 to fix it. Then, the plug rod 57 is pulled up to be separated from the plug groove 56, then the receiving disc 15 on the sliding block 55 is inserted into the winding disc to stabilize the other end of the winding disc, then the plug rod 57 is released, and the spring 58 pushes the plug rod 57 to rebound into the plug groove 56 to fix the sliding block 55. At this time, the two groups of receiving discs 15 limit the two ends of the winding disc, which improves the stability of the winding disc when rotating. After the winding disc is received, the handle 59 can be pulled to make the sliding block 55 slide on the lifting frame 53, so that the sliding block 55 and the receiving disc 15 on the other end thereof are separated from the winding disc, and then the lifting frame 53 is lowered to reset, and then the received winding disc can be disassembled.

[0094] It should be noted that the switch 66 is a component for controlling the opening and closing of the motor 14, and an alarm component such as an alarm lamp can be externally connected during use, so that the motor 14 can be controlled to stop running when the arc-shaped frame 62 hits the switch 66, and an alarm can be given to the staff;

[0095] The end of the arc-shaped frame 62 close to the support 13 is provided with an arc-shaped plate, and the upper and lower ends of the arc-shaped plate are smoothly processed, so that when the winding disc is rotating to receive the composite material, the arc-shaped frame 62 can be moved by the gradually widening outer diameter of the winding disc during receiving, until the winding disc is received to a suitable outer diameter width, the arc-shaped frame 62 is in contact with the switch 66, and then the accuracy and uniformity of each group of winding discs receiving the composite material are improved by using the arc-shaped frame 62 and the conveying roller 21 for double verification;

[0096] The spring force of the spring 63 can improve the close degree of the composite material when the winding disc is rotating and stored.

[0097] The surface of the sliding frame 65 is provided with a scale groove (as shown in Figure 14 The scale groove can be used to accurately position the sliding frame 65, which is convenient for winding discs of different models and storage needs.

[0098] The left end of the lead screw 67 is provided with a handle, which is convenient for controlling the rotation of the lead screw 67.

[0099] The cable 68 is made of soft material to avoid damage to the cable 68 when the sliding frame 65 moves, and the cable 68 can convey the signal released by the switch 66.

[0100] In this embodiment, when in use, the rotating lead screw 67 drives the sliding frame 65 to slide left and right in the through groove, thereby adjusting the position of the switch 66, which is convenient for winding discs with different storage needs. When the winding disc is rotating and storing the composite material, it will push the arc-shaped frame 62 to move to the right through the gradually increasing outer diameter. After the winding disc is stored to the appropriate outer diameter, the arc-shaped frame 62 will touch the switch 66 at the upper end of the sliding frame 65. At this time, the switch 66 controls the motor 14 to stop running and sends an alarm to prompt the staff that the winding disc has been stored. At the same time, the double verification method of the arc-shaped frame 62 and the conveying roller 21 can improve the accuracy and uniformity of each group of winding discs storing the composite material.

[0101] The working principle of the present application is as follows: when in use, the winding disc for accommodating composite materials is placed on the accommodating disc 15, at this time the groove in the inner circle of the winding disc will extrude the convex strip 16, so that the convex strip 16 shrinks into the empty groove of the accommodating disc 15, and when the winding disc is completely placed, it is fixed in the groove in the inner circle of the winding disc, then the moving block 52 is pushed to make the lifting frame 53 close to the other end of the winding disc, and the lifting frame 53 is pulled up to contact the other end of the winding disc. Then the pull-up plug rod 57 is pulled out of the plug groove 56, then the sliding block 55 is pushed to make the accommodating disc 15 on the sliding block 55 inserted into the winding disc, and the other end of the winding disc is stabilized. Then the screw rod 67 is rotated to drive the sliding frame 65 to slide in the through groove to adjust the position of the switch 66. Then the motor two 23 drives the two sets of conveying rollers 21 to rotate to convey the composite materials, and at the same time, the gear one 22 below drives the gear three 26 to rotate, so that the counter 24 can record the number of rotations of the conveying roller 21, and the length of the composite materials conveyed by the conveying roller 21 can be known by calculating the number of rotations. And when the winding disc rotates to accommodate the composite materials, the outer diameter gradually increases to push the arc-shaped frame 62 to move to the right, and when the winding disc is accommodated to the appropriate outer diameter, the arc-shaped frame 62 will touch the switch 66 at the upper end of the sliding frame 65, at this time the switch 66 controls the motor one 14 to stop running and sends out an alarm to prompt the staff that the winding disc is completed. Further, the double verification method is used to improve the accuracy and uniformity of the number of winding discs accommodated in each set. After the accommodation is completed, the extrusion frame 31 drives the lifting block 32 and the extrusion roller 33 to descend to clamp and fix the composite materials, at the same time, the electric guide rail 34 drives the electric push rod 35 to move the assembly plate 36 until the blade 43 is above the composite materials, then the electric push rod 35 drives the blade 43 to approach the materials, the heating disc 44 operates to preheat the blade 43, when the temperature of the blade 43 reaches the preset range, the control component 42 drives the blade 43 to rotate to cut off the composite materials below. At this time, the external air pump absorbs the debris generated during cutting through the air pipe 45 and the adsorption cover 46. After cutting is completed, the electric guide rail 34 drives the electric push rod 35 to reset to release the fixation of the composite materials, then the motor one 14 drives the accommodating disc 15 to continue rotating to accommodate the remaining materials, and waits for the next round of composite material accommodation work.

[0102] The above is only the preferred embodiment of the present application, it should be pointed out that for ordinary skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, these improvements and refinements should also be considered as the protection scope of the present application.
