DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figure 1-Figure 10As shown, the present invention provides a technical solution: a cutting device for automobile parts production and manufacturing, comprising a frame assembly 1, a power assembly 2 is arranged on the top of the frame assembly 1, a cutting assembly 3 is arranged on the bottom of the power assembly 2, and pressing assemblies 4 and cleaning assemblies 5 are arranged on the outer surfaces of both sides of the power assembly 2. The frame assembly 1 includes a machine table 101, and a cutting seam 102 is opened near the middle position of the table surface of the machine table 101. Racks 104 are fixedly connected to the inner surface walls of both sides of the cutting seam 102 near the edge. The power assembly 2 includes two mounting plates 201, and slide rails 202 are symmetrically fixedly connected to the outer surfaces of the opposite sides of the two mounting plates 201 near the bottom edge. The two mounting plates 2 A hydraulic cylinder 205 is fixedly installed on the outer surface of the opposite side of 01 near the top center, and the outer surface of the mounting plate 201 is symmetrically provided with slide grooves 203. The cutting component 3 includes an I-shaped frame 301. The outer surfaces of both sides of the I-shaped frame 301 are provided with built-in grooves 302. A plurality of grinding rollers 303 are rotatably connected between the front and rear inner walls of the built-in grooves 302. A plurality of first gears 304 are rotatably connected to the front and rear outer surfaces of the I-shaped frame 301. The first gear 304 is fixedly connected to the grinding roller 303 through the shaft, and the first gear 304 is meshingly connected to the rack 104. The pressing component 4 includes a connecting frame 401, and the cleaning component 5 includes two sets of mounting frames 504 and a connecting shell 501.

[0023] Two mounting plates 201 are fixedly connected to the upper position between the front and rear inner walls of the machine platform 101. The upper swing rods 204 are rotatably connected to the two upper corners of the outer surfaces of the opposite sides of the two mounting plates 201. The bottom end of the hydraulic cylinder 205 is fixedly connected to the first connecting rod 206. Both ends of the first connecting rod 206 are fixedly connected to the connecting shaft 207. The outer surfaces of the two connecting shafts 207 are rotatably connected to the second connecting rods 208. The rear surfaces of the two second connecting rods 208 are rotatably connected to the bottom ends of the two upper swing rods 204. The machine platform 101 is composed of a table, a side frame and a bottom frame. The mounting plates 201 are fixed to the side frames. The bottom frame is used to support the device off the ground. The upper end of the upper swing rod 204 is rotatably connected to the mounting plate 201, and the lower end is rotatably connected to the second connecting rod 208.

[0024] The front surfaces of the two second connecting rods 208 are rotatably connected to the movable rod 209, and the bottom end of the movable rod 209 is rotatably connected to the rotating seat 210. The outer surfaces of the opposite sides of the two rotating seats 210 are fixedly connected to the sliding bar 211 extending downward. The outer surface of the sliding bar 211 slides and fits with the inner surface wall of the slide rail 202. The outer surface of the connecting shaft 207 slides and fits with the inner surface wall of the slide groove 203 and extends to the outside. The connecting shaft 207 is used to rotatably connect the first connecting rod 206 and the second connecting rod 208. After the hydraulic cylinder 205 is started, it will push the first connecting rod 206 to descend. As the first connecting rod 206 descends, the inclined second connecting rod 208 will gradually rotate to a horizontal state. At this time, the upper swing rod 204 and the movable rod 209 will be in the same straight line, and the punching knife 305 will move to the lowest point and cut the automobile sheet parts and pass through the cutting seam 102.

[0025] The outer surface of the slide bar 211 is fixedly connected to the outer surface of the I-shaped frame 301, and a punching knife 305 is fixedly connected to the bottom of the I-shaped frame 301. The positions of the punching knife 305 and the cutting seam 102 correspond to each other. The I-shaped frame 301 is mainly used to install the grinding roller 303 and connect the punching knife 305 and the rotating seat 210. The cutting seam 102 is used to avoid the punching knife 305. The main body of the I-shaped frame 301 is a rectangular frame, and a longitudinal reinforcing rib is provided in the middle of the interior. The reinforcing rib separates two built-in grooves 302 from the hollow inside of the I-shaped frame 301. The slide bar 211 is arranged inside the slide rail 202 and can only move linearly up and down, thereby limiting the moving path of the I-shaped frame 301 and the rotating seat 210.

[0026] The use steps of the present invention are as follows: when in use, the automobile sheet parts to be cut are fixed on the machine platform 101, and then the hydraulic cylinder 205 is started to push the first connecting rod 206 to descend. As the first connecting rod 206 descends, the inclined second connecting rod 208 will gradually rotate to a horizontal state. At this time, the upper swing rod 204 and the movable rod 209 will be in the same straight line, and the punching knife 305 will move to the lowest point and cut the automobile sheet parts and pass through the cutting seam 102. During this process, the hydraulic cylinder 205 is in a state of continuously pushing the first connecting rod 206 to move downward. At this time, the inner end of the second connecting rod 208 will continue to descend and rotate to an inclined state. At this time, the connection between the upper swing rod 204 and the movable rod 209 and the second connecting rod 208 will be subjected to tension and move inward. The upper swing rod 204 and the movable rod 209 will be converted into an inclined state again. At this time, the bottom end of the movable rod 209 will rotate with the rotating seat 210 and pull the I-frame 301 and the punching knife 305 starts to move up, and when the hydraulic cylinder 205 contracts, the punching knife 305 will move up and down again. Each time the hydraulic cylinder 205 is started, the punching knife 305 will move up and down twice, ensuring the effective cutting of the automobile sheet parts. In addition, when the punching knife 305 cuts the automobile sheet parts during the lifting process, the first gear 304 on the surface of the I-frame 301 will mesh with the rack 104 on the inner wall of the cutting seam 102 during the lifting process. As the I-frame 301 rises and falls, the first gear 304 will drive the grinding roller 303 inside the built-in groove 302 to rotate rapidly. The rotating grinding roller 303 will contact the cut surface of the automobile sheet parts during the process and have a grinding effect. This design ensures that each time the automobile sheet parts are cut, their cut surfaces will be polished four times by the grinding roller 303, thereby achieving the effect of removing cut burrs, simplifying the processing flow, and improving the overall production efficiency of automobile parts.

[0027] Embodiment 2: Figure 1-Figure 3 , Figure 6 , Fig. 9 and Fig.10 As shown, the difference between the embodiment and the embodiment is that the end of the connecting shaft 207 is fixedly connected to a strip shell 212, and a plurality of triangular blocks 213 are slidably connected inside the strip shell 212. A spring rod 214 is fixedly connected between the outer surface of the triangular block 213 and the inner surface wall of the strip shell 212. The mounting frame 504 and the connecting shell 501 are both fixedly connected to the opposite outer surfaces of the two mounting plates 201. The connecting shell 501 is located above the mounting frame 504. The strip shell 212 is connected to the connecting shaft 207. Therefore, when the hydraulic cylinder 205 is extended or retracted, the connecting shaft 207 will drive the strip shell 212 to move up and down. A large number of grooves for accommodating the triangular blocks 213 are provided on the surface of the strip shell 212. The spring rod 214 is installed in the groove. After being squeezed, the triangular blocks 213 will retract into the strip shell 212 and squeeze the spring rod 214 to shrink. After losing pressure, the spring rod 214 will rebound and squeeze the triangular blocks 213 to reset.

[0028] The number of each group of connecting shells 501 is set to one, and the number of each group of mounting frames 504 is set to two. The outer surfaces of the opposite sides of the two mounting frames 504 are rotatably connected with a rotating shaft 505. The outer surface of the rotating shaft 505 is sleeved with a friction ring 506. The outer surface of the friction ring 506 is connected to a ratchet gear 507. The outer surfaces of the two ratchet gears 507 are fixedly connected with an eccentric rod 508 near the edge. The ratchet gear 507 cooperates with the triangular block 213. The surface of the friction ring 506 is provided with anti-slip grooves, which can ensure that there is a certain friction force when the ratchet gear 507 rotates. When the two ratchet gears 507 rotate, the eccentric rod 508 will undergo eccentric movement.

[0029] The outer surface of the eccentric rod 508 is rotatably connected to a connecting handle 509 near the middle position, a sliding groove 502 is opened inside the connecting shell 501, and a sliding sleeve 503 is slidably connected between the inner surface walls of the sliding groove 502. The top of the connecting handle 509 slides through the sliding sleeve 503 and extends upward. The bottom of the connecting handle 509 is fixedly connected to a cleaning brush 510. The bottom of the machine 101 is located below the cutting seam 102 and is fixedly connected to a slag bucket 103. When the eccentric rod 508 moves, it will drive the connecting The handle 509 moves as a whole around a circular path. The sliding groove 502 inside the connecting shell 501 is used to limit the sliding sleeve 503 so that it can only move horizontally and linearly. The sliding sleeve 503 is used to limit the connecting handle 509 so that it will always remain in a vertical state during the movement. The bottom of the cleaning brush 510 is nylon bristles, which will bend when squeezed by the machine 101 and have a certain elastic force when detached, so as to sweep the debris generated in the process of deburring the cut surface of the automotive sheet metal parts into the cutting seam 102.

[0030] The use steps of the present invention are as follows: when the hydraulic cylinder 205 is started to extend and drives the punching knife 305 to cut the automobile sheet parts, as the first connecting rod 206 descends, the connecting shaft 207 used to rotatably connect the first connecting rod 206 and the second connecting rod 208 will drive the strip shell 212 to descend linearly. At this time, the inclined surface of the triangular block 213 on the surface of the strip shell 212 will fit the inclined surface of the ratchet teeth on the surface of the ratchet gear 507. Since the ratchet gear 507 is installed on the rotating shaft 505 through the friction ring 506, the inclined surface of the triangular block 213 cannot push the ratchet gear 507 to rotate under the action of friction, and will squeeze the spring rod 214 to shrink and retract into the strip shell 212 under the action of reaction force. When the triangular block 213 passes over the ratchet gear 507, the spring rod 214 rebounds and pushes the triangular block 213 to reset. When the cutting operation is completed, the hydraulic cylinder 205 starts to shrink, and the strip shell 212 will move upward. At this time, the plane of the triangular block 213 and the ratchet gear 50 7 is fitted on the plane, and during the upward movement, the ratchet gear 507 will be driven to rotate outward. At this time, the ratchet gear 507 will perform a circular motion with the rotating shaft 505 as the center through the eccentric rod 508. During the process, the overall movement path of the connecting handle 509 rotatably connected to the eccentric rod 508 is consistent with the movement path of the eccentric rod 508. At the same time, the upper end of the connecting handle 509 is restricted by the sliding sleeve 503, so the connecting handle 509 will always remain in a vertical state during the movement, so that the cleaning brush 510 and the machine table 101 remain parallel and rotate in a circle. During the process, the cleaning brush 510 will fall from a high place to the top of the machine table 101 away from the cutting seam 102, then move toward the cutting seam 102 and bend the bristles at the bottom. After approaching the cutting seam 102, it will gradually move upward and leave the machine table 101, so that the debris generated when the part cut surface is polished and deburred is swept into the cutting seam 102, and finally discharged from the slag discharge bucket 103 to the outside, thereby maintaining the cleanliness of the table surface.

[0031] Embodiment 3: Figure 1-Figure 3 and Figure 8 As shown, the difference between the basis of the combined embodiment is that the connecting frame 401 is fixedly connected to the outer surface of the strip shell 212 near the bottom, and a rectangular opening is opened at the connecting frame 401 near the cleaning component 5. When the connecting frame 401 is raised or lowered, the rectangular opening on the surface is mainly used to avoid the cleaning component 5.

[0032] The outer surface of the connecting frame 401 is located at a position away from the mounting plate 201 and is slidably connected with a slide rod 402. The bottom end of the slide rod 402 is fixedly connected with a pressure plate 404. The outer surface of the slide rod 402 near the bottom is sleeved with a first spring 406. The slide rod 402 can slide up and down inside the connecting frame 401. When the pressure plate 404 is squeezed downward, as the connecting frame 401 descends, the slide rod 402 will slide relative to the connecting frame 401. The first spring 406 will generate a reaction force after being affected by the connecting frame 401, so that the pressure plate 404 firmly presses the cut-off parts below.

[0033] The top of the first spring 406 conflicts with the bottom of the connecting frame 401, and the bottom of the first spring 406 conflicts with the top of the pressure plate 404. The bottom of the pressure plate 404 is bonded and connected with a rubber pad 405. The top of the slide bar 402 is fixedly connected with an anti-slip head 403. The rubber pad 405 has certain deformation characteristics, which can prevent the pressure plate 404 from hard squeezing of automobile sheet parts and causing damage. The anti-slip head 403 is used to limit the slide bar 402 to prevent the slide bar 402 from falling down from the connecting frame 401.

[0034] The use steps of the present invention are as follows: when the hydraulic cylinder 205 is started to cut the automobile sheet parts on the machine 101, as the hydraulic cylinder 205 extends, the strip shell 212 that follows the connection shaft 207 to descend will drive the connection frame 401 to move downward, and as the connection frame 401 descends, the rubber pad 405 under the pressure plate 404 will press the automobile sheet parts on the machine 101, and as the connection frame 401 descends, the first spring 406 will be compressed and contracted and generate a reaction force to make the pressure plate 404 tightly press the automobile sheet parts on the machine 101, thereby avoiding the deviation of parts during the cutting process and causing the processing quality to decrease, thereby improving the product quality of automobile parts manufacturing.

[0035] Among them, the hydraulic cylinder 205 is all existing technology, and its components and operating principles are all public technology, which will not be explained in detail here.

[0036] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
