Description

Technical Field

[0001] The present invention relates to the technical field of metal punching devices, and in particular to a punching and positioning device for a chassis frame component of a new energy vehicle. Background Art

[0002] In the metalworking field, a punching and positioning device for chassis frame components of new energy vehicles uses mechanical transmission and an elastic clamping structure to precisely position and secure crossbeams, meeting the high-precision requirements of the punching process. This device, which uses a drive rod to move the clamping assembly and incorporates pneumatic transmission and a triangular support structure, adapts to crossbeams of varying sizes. The synergistic action of rollers and non-Newtonian fluid-filled bladders ensures damage-free fixation and vibration suppression. Suitable for automated punching production lines, this device is crucial for improving the processing quality and efficiency of chassis components for new energy vehicles.

[0003] Traditional punching positioning devices have significant shortcomings. In terms of positioning compatibility, traditional equipment mostly uses a rigid clamping structure, which cannot automatically adjust the clamping force according to the size of the beam, resulting in deformation of large-sized components due to excessive pressure, and displacement of small-sized components due to loose fixation, affecting the punching accuracy. The structural stability is insufficient. When processing narrow beams for a long time, the mounting frame is prone to bending and deformation due to uneven force, causing the shaft to jam or positioning deviation. The lack of surface protection means that traditional rollers or clamps directly contact the surface of the component, which can easily cause scratches or crushing, affecting the appearance quality of the component and subsequent assembly. The degree of automation is low, and there is a lack of a dynamic locking mechanism. During the punching process, the component may undergo slight displacement due to vibration, resulting in hole position deviation, and automatic limiting of the shaft cannot be achieved. Frequent manual adjustments are required, reducing production efficiency. In addition, the pneumatic system of the traditional device has a delayed response and cannot complete positioning synchronously with the mechanical clamping, resulting in poor process connection and restricting the continuity and stability of the punching process.

[0009] According to one embodiment of the present invention, the auxiliary mechanism includes a baffle, which is symmetrically fixedly connected to the inner surfaces on both sides of the bottom of the mounting frame, and the baffle slides through the movable plate. The top inner surface of the mounting frame is fixedly inlaid with a reinforcement frame, and the reinforcement frame is set to be concave. The lower surface of the middle part of the reinforcement frame is symmetrically hinged with a telescopic rod through a torsion spring, and the bottom of the telescopic rod is hinged to the upper surfaces on both sides of the movable plate through a torsion spring.

[0010] According to one embodiment of the present invention, an elastic plate is fixedly connected to the middle upper surface of the movable plate, the elastic plate is arranged in a semicircular ring shape, the inner surface of the elastic plate is fixedly connected to an extrusion bag, the bottom of the extrusion bag is fixedly connected to the middle upper surface of the movable plate, and the gas gathering box is connected to the internal cavity of the extrusion bag through a connecting tube.

[0011] According to one embodiment of the present invention, a pressure chamber is provided on the top side surface of the mounting frame at the bottom, and an extrusion plate is elastically and slidably inserted in the pressure chamber, and the outer end of the extrusion plate initially protrudes out of the mounting frame. Mounting grooves are symmetrically provided in the two side walls on the top of the mounting frame, and an annular capsule is fixedly connected in the mounting groove. The internal cavity of the annular capsule is connected to the pressure chamber, and a No. 1 plug-in plate is fixedly connected to the inner surface of the annular capsule. A No. 2 plug-in plate is elastically and slidably inserted at both ends of the No. 1 plug-in plate, and the No. 1 plug-in plate and the No. 2 plug-in plate are combined into a ring shape.

[0012] According to one embodiment of the present invention, a plug-in block is fixedly connected to the inner surface of the No. 1 plug-in board, and plug-in slots are provided on the outer surfaces of both ends of the rotating shaft, wherein the plug-in block is arranged opposite to the plug-in slots.

[0013] According to one embodiment of the present invention, the outer surface of the roller body is fixedly sleeved with a filling bag, the interior of the filling bag is filled with non-Newtonian fluid, and an expansion tube is fixedly connected to the filling bag, and the expansion tube is made of rubber material, and both ends of the expansion tube are fixedly connected with an air pressure ring, and the air pressure ring is symmetrically fixedly sleeved on the outer surfaces of both ends of the rotating shaft, and auxiliary grooves are opened at both ends of the rotating shaft, and the auxiliary grooves are connected with the internal cavity of the air pressure ring, and the top outer surface of the mounting frame is fixedly buckled and connected with a gas gathering cover, and the gas gathering cover is arranged on the outer sides of both ends of the rotating shaft, and a connecting pipe is reserved on the gas gathering cover, and the bottom surface of the movable plate is fixedly connected with the auxiliary bag, and the bottom of the auxiliary bag is fixedly connected to the bottom upper surface of the mounting frame, and the internal cavity of the auxiliary bag is connected with the internal cavity of the gas gathering cover through the connecting pipe. When it is necessary to punch the U-shaped crossbeam of the automobile chassis, the two ends of the crossbeam can be placed between the upper and lower clamping assemblies, and then the motor is used to cause The driving rod starts to rotate. When the driving rod rotates, it will drive the clamping assemblies at both ends to approach each other through the thread, and at this time drive the connecting frame downward at the same time, and then start to squeeze the tubular bag through the moving frames approaching each other, and transmit the internal air pressure of the tubular bag to the gas gathering box. As the air pressure in the gas gathering box gradually increases, it will push the two fixed blocks to move closer to each other, and finally the sides of the two fixed blocks that are close to each other will fit the side surface of the beam, and the horizontal positioning of the beam will be completed by the squeezing of the fixed blocks. At the same time, the downward moving connecting frame drives the top clamping assembly to be in a downward state. After the fixed block completes the horizontal positioning of the beam, the rollers on the upper and lower sides are respectively attached to the upper and lower surfaces of the two ends of the beam. As the driving rod continues to rotate, the two sets of clamping assemblies continue to move closer to each other, that is, finally the longitudinal clamping and fixation of the beam is completed by the clamping assemblies approaching each other, so that the center axis of the beam is consistent with the center axis of the base plate, thereby completing the positioning of the beam.

[0014] The present invention provides a punching and positioning device for chassis frame components of new energy vehicles. It has the following beneficial effects:

[0015] (1) The punching positioning device of the chassis frame component of the new energy vehicle, when the clamping components on the upper and lower sides approach each other and squeeze the two ends of the beam, the mounting frames on the upper and lower sides will move relatively outward relative to the movable plate fixedly connected to the movable frame. Finally, when the mounting frame moves to the extreme, the telescopic rod on the movable plate completes the support of the middle part of the reinforcement frame, forming a triangular support structure, which is conducive to the ends of the mounting frames that are close to each other to always remain horizontal after long-term use, avoiding the problem that the middle part of the mounting frame is bent and the rotating shaft cannot roll due to long-term processing of narrow beams. The problem of scratches on the two ends of the beam is avoided by the rotation of the roller body when the beam is longitudinally positioned, and the provided roller body can also greatly improve the extrusion and fitting effect with the two ends of the beam, thereby improving the fixing effect of the beam.

[0016] (2) The punching positioning device of the chassis frame component of the new energy vehicle has a filling bag sleeved on the outer surface of the roller body, and the filling bag is filled with non-Newtonian fluid. That is, when the two ends of the beam are slowly squeezed and fixed at the beginning, the filling bag will be deformed due to the squeezing force, so that the outer surface of the deformation bag is firmly embedded with the upper and lower surfaces of the beam, so that the non-Newtonian fluid inside the deformation bag is hardened by the rapid short-amplitude vibration of the beam during punching, so that the two ends of the beam cannot move, and the beam is automatically strengthened and fixed during processing, avoiding the problem of punching accuracy caused by the misalignment of the beam due to vibration during punching, and the mounting frame will also squeeze the elastic plate when it moves relative to the movable plate. The reverse squeezing provided by the elastic plate and the squeezing bag ensures the working stability of the telescopic rod, avoiding the problem of breakage of the telescopic rod due to excessive squeezing. At the same time, when the squeezing bag is squeezed, its internal air pressure will be transmitted to the air gathering box, providing further air pressure support for the fixing block, thereby ensuring that the horizontal fixing effect of the beam is further enhanced by the fixing block during punching, and further improving the punching accuracy.

[0017] (3) The punching positioning device of the chassis frame component of this new energy vehicle, when the mounting frames on the left and right sides move closer to each other, the extrusion plate on the mounting frame at the bottom will contact and squeeze the bottom bend of the beam. While achieving longitudinal positioning, the extrusion plate is also squeezed into the pressure chamber, and the air pressure in the pressure chamber is transmitted to the annular bag in the mounting groove, causing the annular bag to expand, pushing the No. 1 plug-in board and the No. 2 plug-in board to start shrinking, and finally inserting the plug-in block on the inner surface of the No. 1 plug-in board into the plug-in groove at both ends of the rotating shaft, limiting the rotating shaft, and then automatically locking the rotating shaft when completing the longitudinal positioning of the beam, so that the roller body cannot continue to rotate, and the strong friction provided by the surface of the filling bag further avoids the problem of punching accuracy caused by the displacement of the beam during punching. When the movable plate moves relative to the mounting frame, the auxiliary bag will be stretched, so that the auxiliary bag is in a negative pressure state, thereby extracting air pressure into the gas hood, making the auxiliary grooves at both ends of the rotating shaft in a negative pressure state, and finally making the air pressure ring in a negative pressure state, that is, the air pressure is extracted from the expansion tube, causing the expansion tube to undergo negative pressure deformation, greatly reducing the extrusion and destructive force of the expansion tube by the crossbeam, and limiting the moving distance of the non-Newtonian fluid by the provided expansion tube, avoiding the problem of local excessive accumulation of the non-Newtonian fluid affecting the fixing effect, and after the punching is completed, the auxiliary bag begins to reset, and then the internal air pressure is re-input into the auxiliary groove, and the expansion tube is caused to expand and reset through the air pressure ring, so that after the punching is completed, the automatically reset expansion tube is used to help the filling bag reset, thereby facilitating the continuous punching operation of the crossbeam.

The baffle 51 slides through the movable plate 45. The top inner surface of the mounting frame 44 is fixedly inlaid with a reinforcement frame 52. The reinforcement frame 52 is set to be concave. The lower surface of the middle part of the reinforcement frame 52 is symmetrically hinged with a telescopic rod 53 through a torsion spring. The bottom of the telescopic rod 53 is hinged to the upper surfaces on both sides of the movable plate 45 through a torsion spring.

[0036] An elastic plate 54 is fixedly connected to the middle upper surface of the movable plate 45, and the elastic plate 54 is arranged in a semicircular ring shape. An extrusion bag 55 is fixedly connected to the inner surface of the elastic plate 54, and the bottom of the extrusion bag 55 is fixedly connected to the middle upper surface of the movable plate 45. The gas gathering box 411 is connected to the internal cavity of the extrusion bag 55 through a connecting tube.

[0037] A pressure chamber 56 is provided on the top side surface of the mounting frame 44 at the bottom, and an extrusion plate 57 is elastically and slidably inserted in the pressure chamber 56. The outer end of the extrusion plate 57 initially protrudes out of the mounting frame 44, and mounting grooves 58 are symmetrically provided in the two side walls of the top of the mounting frame 44. An annular capsule 59 is fixedly connected in the mounting groove 58. The internal cavity of the annular capsule 59 is connected to the pressure chamber 56. The inner surface of the annular capsule 59 is fixedly connected to the No. 1 plug-in plate 510, and the No. 2 plug-in plate 511 is elastically and slidably inserted at both ends of the No. 1 plug-in plate 510, and the No. 1 plug-in plate 510 and the No. 2 plug-in plate 511 are combined into a ring shape.

[0038] The inner surface of the No. 1 plug-in board 510 is fixedly connected with a plug-in block 512 , and the outer surfaces of both ends of the rotating shaft 47 are provided with plug-in slots 513 , wherein the plug-in block 512 and the plug-in slots 513 are arranged opposite to each other.

[0039] The outer surface of the roller body 48 is fixedly sleeved with a filling bag 514, and the interior of the filling bag 514 is filled with non-Newtonian fluid. An expansion tube 515 is fixedly connected to the filling bag 514, and the expansion tube 515 is made of rubber material. The two ends of the expansion tube 515 are fixedly connected with air pressure rings 516, and the air pressure rings 516 are symmetrically fixedly sleeved on the outer surfaces of the two ends of the rotating shaft 47. Auxiliary grooves 517 are provided at both ends of the rotating shaft 47. The auxiliary grooves 517 are connected to the internal cavity of the air pressure ring 516, and the top outer surface of the mounting frame 44 is fixedly buckled with a gas gathering cover 518. The gas gathering cover 518 is arranged on the outer sides of the two ends of the rotating shaft 47, and a connecting pipe is reserved on the gas gathering cover 518. The bottom surface of the movable plate 45 is fixedly connected with an auxiliary bag 519, and the bottom of the auxiliary bag 519 is fixedly connected to the bottom upper surface of the mounting frame 44. The internal cavity of the auxiliary bag 519 is connected with the internal cavity of the gas gathering cover 518 through a connecting pipe.

[0040] During operation, when it is necessary to punch a hole in the U-shaped crossbeam of the automobile chassis, the two ends of the crossbeam can be placed between the upper and lower clamping assemblies 43, and then the driving rod 41 starts to rotate through the motor. When the driving rod 41 rotates, the clamping assemblies 43 at both ends are driven to approach each other through the thread, and at this time, the connecting frame 410 is driven downward, and then the tubular capsule 413 is squeezed through the moving frames 46 that are close to each other, and the internal air pressure of the tubular capsule 413 is transported to the air collecting box 411. As the air pressure in the air collecting box 411 gradually increases, the two fixed blocks 412 are pushed to move closer to each other. Finally, the sides of the two fixed blocks 412 that are close to each other are attached to the side surface of the crossbeam, and the lateral positioning of the crossbeam is completed by squeezing the fixed blocks 412. At the same time, the downward-moving connecting frame 410 drives the top clamping assembly 43 to be in a downward state. After the fixed block 412 completes the lateral positioning of the beam, the rollers 48 on the upper and lower sides are respectively fitted to the upper and lower surfaces of the two ends of the beam. As the driving rod 41 continues to rotate, the two sets of clamping assemblies 43 continue to move closer to each other, that is, finally, the longitudinal clamping and fixing of the beam is completed by the clamping assemblies 43 approaching each other, so that the central axis of the beam is consistent with the central axis of the bottom plate 1, thereby completing the positioning of the beam. When the clamping assemblies 43 on the upper and lower sides approach each other and squeeze the two ends of the beam, the upper and lower mounting frames 44 will move relatively outward relative to the movable plate 45 fixedly connected to the movable frame 46. Finally, when the mounting frame 44 moves to the extreme The telescopic rod 53 on the movable plate 45 completes the support of the middle part of the reinforcement frame 52 to form a triangular support structure, which is beneficial for the ends of the mounting frames 44 that are close to each other to always remain horizontal after long-term use, avoiding the problem that the middle part of the mounting frame 44 is bent due to long-term processing of narrow beams, resulting in the inability of the rotating shaft 47 to roll. The roller body 48 is used to longitudinally position the beam, and the rotation of the roller body 48 avoids the problem of the two ends of the beam being scratched. The roller body 48 can also greatly improve the squeezing and fitting effect with the two ends of the beam, thereby improving the fixing effect of the beam. Since the outer surface of the roller body 48 is provided with a filling bag 514, and the filling bag 514 is filled with non-Newtonian fluid, that is, when the two ends of the beam are slowly squeezed and fixed at the beginning, the filling bag 514 is filled. The capsule 514 will be deformed due to the extrusion force, so that the outer surface of the deformation capsule is firmly embedded with the upper and lower surfaces of the beam, so that the non-Newtonian fluid inside the deformation capsule is hardened through the rapid short-amplitude vibration of the beam during punching, so that the two ends of the beam cannot move, and the beam is automatically strengthened and fixed during processing, avoiding the problem of punching accuracy caused by the misalignment of the beam due to vibration during punching, and the mounting frame 44 will also squeeze the elastic plate 54 when it is displaced relative to the movable plate 45. The reverse extrusion provided by the elastic plate 54 and the extrusion capsule 55 ensures the working stability of the telescopic rod 53, avoiding the problem of breakage caused by excessive extrusion of the telescopic rod 53. At the same time, when the extrusion capsule 55 is squeezed, its internal air pressure is transmitted to the gas collection box 411.The cam 414 is pressed against the bottom surface of the support frame 416, and the cam 416 is pressed against the bottom surface of the support frame 416. The cam 414 is pressed against the bottom surface of the support frame 416, and the cam 416 is pressed against the bottom surface of the support frame 416. The cam 414 is pressed against the bottom surface of the support frame 416, and the cam 416 is pressed against the bottom surface of the support frame 416. The displacement during punching causes a problem in punching accuracy. When the movable plate 45 moves relative to the mounting frame 44, it stretches the auxiliary capsule 519, causing the auxiliary capsule 519 to be in a negative pressure state, thereby extracting air pressure into the gas collecting cover 518, causing the auxiliary grooves 517 at both ends of the rotating shaft 47 to be in a negative pressure state, and finally causing the air pressure ring 516 to be in a negative pressure state, that is, the air pressure is extracted from the expansion tube 515, causing the expansion tube 515 to be deformed under negative pressure, greatly reducing the extrusion and destructive force of the expansion tube 515 on the crossbeam. The expansion tube 515 is provided to limit the movement distance of the non-Newtonian fluid, avoiding the problem of local excessive accumulation of the non-Newtonian fluid affecting the fixing effect. After the punching is completed, the auxiliary capsule 519 begins to reset, and then its internal air pressure is re-inputted into the auxiliary groove 517. The air pressure ring 516 causes the expansion tube 515 to expand and reset. After the punching is completed, the automatically reset expansion tube 515 is used to help the filling capsule 514 reset, thereby facilitating the continuous punching operation of the crossbeam.
