Description

Technical Field

[0001] The invention relates to the field of vehicle chassis punching, in particular to a vehicle chassis punching device. Background Art

[0002] The punching device for vehicle chassis is a device or tool used to punch holes in metal plates. The punching device usually includes a punch and a base. The punch creates holes in the metal plate through pressure or impact force on the base. In addition, the punching device can be customized according to the diameter, shape and number of the required holes to meet the requirements of different models and designs. During the vehicle manufacturing process, the punching device is usually integrated into the automated production line to improve production efficiency and consistency.

[0003] The chassis punching devices on the market are usually used to create holes on the vehicle chassis in order to install parts or make other customized modifications. In some cases, in order to achieve better operating results and hole quality, the vehicle chassis needs to be flipped. The vehicle chassis is usually large in size. If the vehicle chassis cannot be flipped manually, it is necessary to use an additional flipping mechanical device to flip the vehicle chassis. The flipping mechanical device requires additional space to install and operate, which will increase the occupied area of ​​the workplace, especially for small workshops or limited space. It will cause inconvenience. Secondly, the additional mechanical device means that the complexity of the equipment increases, and maintenance and maintenance will become more complicated. If the position or angle of the vehicle chassis cannot be adjusted, the punching angle of the chassis punching device will be limited, thereby increasing the difficulty and inconvenience of operation, which will make it difficult for the chassis punching device to achieve the ideal hole processing effect and even affect the accuracy and quality of the holes.

[0004] On the one hand, chassis punching devices on the market usually use conveyor belt transportation instead of fixing the vehicle chassis during transportation, which will cause the chassis to shake or move during the punching process, making the position of the vehicle chassis unstable, thereby affecting the processing precision and accuracy, especially for workpieces that require high-precision processing. Insufficient stability will lead to processing errors. At the same time, failure to fix the vehicle chassis will increase the safety risks of operators and equipment. During the punching process, if the chassis suddenly moves or detaches from the conveyor belt, accidents may occur, causing personal injury or equipment damage. In addition, failure to fix the chassis will require frequent adjustments to the position of the vehicle chassis during processing, thereby increasing processing time and labor costs and reducing processing efficiency. On the other hand, nuts are usually used to fix the vehicle chassis on the market. Although this method has a low cost and good fixing effect, the installation and removal of the nuts require specific tools to complete the replacement, such as screwdrivers. If the user does not have these tools, they cannot install and remove them, which leads to certain limitations.

[0005] In addition, the chassis punching devices on the market cannot automatically clean the vehicle chassis when punching it, and the extra cleaning step requires increasing the number of times the vehicle chassis is moved. The vehicle chassis is generally large in size and the moving steps are cumbersome. At the same time, the extra cleaning step will affect the punching efficiency. Secondly, the dirt and debris on the surface of the vehicle chassis during the punching process of the equipment will affect the full contact between the punching device and the chassis, which will lead to a decrease in processing accuracy.

[0006] Therefore, it is necessary to provide a punching device for a vehicle chassis to solve the above problems. Summary of the invention

[0014] Preferably, the material of the connecting block is set to be Z-shaped, and the material of the connecting block is set to be aluminum alloy.

[0015] The punching device for a vehicle chassis provided by the present invention has the following beneficial effects compared with the prior art:

[0016] 1. Through the setting of the flipping assembly, the threaded driving rod drives the lifting platform to rise during the rotation of the threaded driving rod, and the lifting platform rises to drive the trigger rod to contact the top of the concave slide, thereby realizing the flipping of the vehicle chassis. Compared with the traditional vehicle chassis punching device, the use of additional flipping equipment or manual adjustment of the chassis angle to automatically flip the vehicle chassis can reduce the labor intensity of workers and improve work safety. At the same time, there is no need to use additional tools or equipment to flip the vehicle chassis, which improves the operation convenience of the chassis punching device. Secondly, by adjusting the chassis angle, the punching operation can be performed more accurately, avoiding errors caused by inaccurate angles, thereby better controlling the angle and direction of the vehicle chassis during the processing, improving the processing precision and accuracy, thereby improving the processing flexibility, avoiding the placement of machinery for flipping the vehicle chassis next to the vehicle chassis punching device, optimizing the utilization of the working space, reducing the processing time and enhancing the convenience of operation;

[0017] 2. Through the setting of the positioning component, when the vehicle chassis is located between the placement table and the square slide, the threaded groove column passes through the inside of the placement table and the square slide, and the staff can rotate the threaded convex ring through the anti-slip rod to achieve the purpose of tightening the distance between the threaded convex ring and the resistance block, so that the placement table and the square slide can fix the vehicle chassis, ensuring that the vehicle chassis moves steadily during the processing, avoiding processing errors caused by the movement or shaking of the vehicle chassis, improving the processing precision and accuracy of the vehicle chassis, ensuring that the position and size of the processed holes meet the requirements, and reducing the vehicle chassis during the processing. The accidental movement or separation of the chassis can be prevented, thereby reducing the safety risks in the working process, reducing the frequent adjustment of the chassis position during the processing, saving adjustment time and improving the processing efficiency. Secondly, the anti-slip pattern set on the placement table reduces the impact force of the vehicle chassis punching device on the vehicle chassis. Compared with the method of fixing the vehicle chassis with metal materials on the market, when the vehicle chassis punching device processes the vehicle chassis, the vehicle chassis and the metal material will be worn after a long period of friction, which will cause slight differences in the subsequent placement of the vehicle chassis, resulting in the displacement of the punching position of the vehicle chassis.

[0018] 3. Through the setting of the positioning component, when the vehicle chassis is located between the placement table and the square skateboard, the staff only needs to pass the threaded groove column through the inside of the placement table and the square skateboard, and then rotate the threaded convex ring to shorten the distance between the threaded convex ring and the resistance block, and the vehicle chassis can be quickly fixed through the placement table and the square skateboard. When the staff needs to disassemble the vehicle chassis, they only need to rotate the threaded convex ring in the opposite direction and press the pressing rod into the inside of the threaded groove column. Then, the pressing rod will move the resistance block to the inside of the threaded groove column, and finally, the threaded groove column is pulled out of the inside of the placement table and the square skateboard, thereby achieving the purpose of quickly releasing the fixed vehicle chassis. Secondly, compared with the traditional method of fixing with nuts, the staff can rotate the threaded convex ring through the anti-slip rod. The threaded convex ring can be quickly disassembled, so that the staff can rotate the threaded convex ring through the anti-slip rod without the help of additional tools. When the chassis needs to be replaced or repaired, it can be operated more conveniently, saving maintenance time and improving efficiency, achieving the purpose of quickly disassembling the vehicle chassis, saving disassembly time, simplifying the disassembly and assembly steps, avoiding the use of additional specific tools for disassembly and assembly, and reducing the complexity of operation;

[0019] 4. Through the setting of the cleaning component, it is achieved that during the rotation of the power conversion rod, the power conversion rod can drive the top diamond slide bar and the square magnet block to move through the two-way threaded groove, and the square magnet block will magnetically attract the metal slide plate to move horizontally and laterally during the movement, first ensuring that the punching device is in full contact with the surface of the vehicle chassis during the processing. Due to the setting of the third reset spring, the cleaning plate is always fixed to the vehicle chassis through the elasticity of the third reset spring, and the metal slide plate will drive the cleaning plate to clean the vehicle chassis during the movement, so as to remove dust on the surface of the vehicle chassis, keep the surface of the vehicle chassis flat and clean, and avoid processing quality problems caused by interference from dirt or impurities. At the same time, the vehicle chassis can be cleaned in real time by the equipment, avoiding affecting the continuity and efficiency of the processing process, and ensuring the cleanliness and flatness of the vehicle chassis surface.

[0041] The flip assembly includes a dust cover 21, which is fixedly connected to the outer wall of the punching device housing 11, a driving device 22 is fixedly connected to the top of the inner cavity of the dust cover 21, a threaded driving rod 23 is fixedly connected to the output end of the driving device 22, and a lifting platform 24 is threadedly connected to the outer wall of the threaded driving rod 23, and a distance increasing nail 25 is fixedly connected to the bottom of the lifting platform 24, and a limiting column 26 is symmetrically fixedly connected to one side of the lifting platform 24 close to the distance increasing nail 25, and an L-shaped rotating rod 27 is rotatably connected to the inside of the lifting platform 24, and the L-shaped rotating rod 27 is away from the lifting platform 24. A triangular turntable 28 is fixedly connected to one end of the platform 24, and a trigger rod 29 is symmetrically fixedly connected to the end of the triangular turntable 28 away from the lifting platform 24. The distance increasing nail 25 and the end of the L-shaped rotating rod 27 close to the lifting platform 24 are both rotatably connected to a positioning block 210, and a first reset spring 211 is fixedly connected between the two positioning blocks 210. A trapezoidal groove block 212 is fixedly connected to the outer wall of the punching device shell 11, and a concave slide plate 213 is slidably connected to the inside of the trapezoidal groove block 212, and a triangular reset block 214 is fixedly connected to the top of the concave slide plate 213.

[0042] The shape of the concave slide plate 213 matches the shape of the trapezoidal groove block 212 , so that the concave slide plate 213 can slide inside the trapezoidal groove block 212 .

[0043] The positioning assembly includes an L-shaped groove rod 31, which is fixedly connected to the side of the punching device housing 11 away from the trapezoidal groove block 212. Two placement platforms 32 are arranged at the bottom of the inner cavity of the punching device housing 11, one of which is slidably connected to the inside of the L-shaped groove rod 31, and the other is fixedly connected to the end of the L-shaped rotating rod 27 away from the lifting platform 24. The tops of the two placement platforms 32 are fixedly connected to a cross limiting rod 33, and the outer walls of the cross limiting rod 33 are slidably connected to a square slide 34, and the inside of the square slide 34 is symmetrically slidably connected to a screw The groove column 35 has a columnar groove 36 formed inside, a pressing rod 37 is slidably connected inside the columnar groove 36, a second return spring 38 is fixedly connected to the bottom of the pressing rod 37, and one end of the second return spring 38 away from the pressing rod 37 is fixedly connected to the columnar groove 36, a resistance block 39 is symmetrically rotatably connected to the bottom of the pressing rod 37, a threaded convex ring 310 is rotatably connected to the outer side of the threaded groove column 35, an anti-slip rod 311 is fixedly connected to the outer side of the threaded convex ring 310 in a ring-shaped manner, and an arc handle 312 is rotatably connected to the top of the threaded groove column 35.

[0044] The placement platform 32 and the square skateboard 34 are both provided with anti-slip grooves on one side, so that the friction between the placement platform 32 and the square skateboard 34 and the vehicle chassis 13 is increased. The shape of the threaded protrusion ring 310 is adapted to the shape of the threaded groove column 35, so that the threaded protrusion ring 310 can rotate along the outer wall of the threaded groove column 35.

[0045] The cleaning assembly includes a rotating block 41, which is fixedly connected to the bottom of the threaded driving rod 23, and the end of the rotating block 41 away from the threaded driving rod 23 is rotatably connected to the connecting block 42, and the end of the connecting block 42 away from the rotating block 41 is rotatably connected to the rotating column 43, and the end of the rotating column 43 away from the connecting block 42 is fixedly connected to the power conversion rod 44, and the outer wall of the power conversion rod 44 is provided with a bidirectional thread groove 45, and the inside of the bidirectional thread groove 45 is slidably connected to a diamond slide bar 46, and the top of the diamond slide bar 46 is rotatably connected to a square magnet block 47, and the bottom of the inner cavity of the punching device shell 11 is slidably connected to a metal slide plate 48, and the top of the metal slide plate 48 is fixedly connected to a third return spring 49, and the end of the third return spring 49 away from the metal slide plate 48 is fixedly connected to a cleaning plate 410, and the bottom of the inner cavity of the punching device shell 11 is fixedly connected to a strip limiting plate group 411.

[0046] The material of the connecting block 42 is set to be Z-shaped, and the material of the connecting block 42 is set to be aluminum alloy, so that the power of the rotating block 41 can be transmitted to the rotating column 43 through the connecting block 42, and it has the effect of wear resistance and hard texture. A brush is set on the top of the cleaning plate 410, and the brush material of the cleaning plate 410 is set to polypropylene, so that the cleaning plate 410 is convenient for cleaning the vehicle chassis 13.

[0047] During the rotation of the threaded drive rod 23, the threaded drive rod 23 will drive the connecting block 42 to rotate through the rotating block 41, and the connecting block 42 will drive the rotating column 43 to rotate synchronously, and then the rotating column 43 will drive the power conversion rod 44 fixed thereto to rotate, and during the rotation of the power conversion rod 44, the two-way thread groove 45 will drive the diamond slide bar 46 to move back and forth laterally, and the diamond slide bar 46 will drive the square magnet block 47 on the top to magnetically attract the metal slide plate 48 to move back and forth laterally, and the metal slide plate 48 will drive the cleaning plate 410 to clean the vehicle chassis 13 through the third return spring 49 on the top, and when the chassis punching device flips and punches the vehicle chassis 13, due to the upward movement of the vehicle chassis 13, the third return spring 49 will gradually elastically stretch to push the cleaning plate 410 to always contact the bottom of the vehicle chassis 13, so as to achieve the purpose of real-time cleaning of the vehicle chassis 13.

[0048] Working principle: In the initial state, the L-shaped rotating rod 27 conflicts with the triangular reset block 214, the first reset spring 211 is not stretched, the second reset spring 38 is not compressed, the third reset spring 49 is compressed, and the placement table 32 is located at the bottom of the L-shaped groove rod 31.

[0049] When working, when the chassis punching device punches holes in the vehicle chassis 13 through the hydraulic punch 12, the vehicle chassis 13 needs to be placed between the placement table 32 and the square slide 34 first, and the staff first holds the threaded groove column 35, and then the staff presses the pressing rod 37 into the inside of the columnar groove 36, and then the pressing rod 37 slides to the bottom of the columnar groove 36, and at the same time, the pressing rod 37 gradually compresses the second return spring 38, and the pressing rod 37 drives the bottom resistance block 39 to rotate into the inside of the columnar groove 36. When the resistance block 39 is completely moved to the inside of the threaded groove column 35, the staff holds the threaded groove column 35 and passes through the inside of the placement table 32 and the square slide 34;

[0050] When the level of the friction block 39 is lower than the level of the placement table 32, the staff stops pressing the pressing rod 37, and then the second return spring 38 elastically extends to push the pressing rod 37 to move toward the top direction of the columnar groove 36. At the same time, the pressing rod 37 drives the friction blocks 39 on both sides to move toward the outside of the threaded groove column 35. At this time, the staff rotates the threaded convex ring 310 through the anti-slip rod 311. Because the shape of the threaded convex ring 310 is compatible with the shape of the threaded groove column 35, the threaded convex ring 310 rotates along the outer wall of the threaded groove column 35. Then the threaded convex ring 310 gradually conflicts with the top of the square slide plate 34. At this time, the staff continues to rotate the anti-slip rod 311, so that the threaded convex ring 310 drives the square slide plate 34 to move toward the placement table 32. While the square slide plate 34 moves along the cross limit rod 33, the square slide plate 34 gradually conflicts with the vehicle chassis 13. At the same time, because the distance between the threaded convex ring 310 and the friction block 39 is continuously shortened, the friction block 39 then conflicts with the bottom of the placement table 32.

[0051] When the staff is unable to rotate the anti-skid rod 311, the square slide 34 and the placement table 32 are restricted by the threaded convex ring 310 and the abutment block 39. At this time, the vehicle chassis 13 is fixed between the placement table 32 and the square slide 34, thereby achieving the purpose of quickly fixing the vehicle chassis 13. By setting the positioning component, when the vehicle chassis 13 is located between the placement table 32 and the square slide 34, the threaded groove column 35 passes through the inside of the placement table 32 and the square slide 34. At this time, the staff can rotate the threaded convex ring 310 through the anti-skid rod 311, thereby achieving the purpose of tightening the distance between the threaded convex ring 310 and the abutment block 39. Because the placement table 32 and the square slide 34 are close to each other, The sides are provided with anti-skid patterns, so that the friction between the placing platform 32, the square slide plate 34 and the vehicle chassis 13 is increased, so that the placing platform 32 and the square slide plate 34 can fix the vehicle chassis 13, ensuring that the vehicle chassis 13 maintains a stable position and posture during the processing, avoiding processing errors caused by the movement or shaking of the vehicle chassis 13, improving the processing precision and accuracy of the vehicle chassis 13, ensuring that the position and size of the processed holes meet the requirements, reducing the accidental movement or separation of the vehicle chassis 13 during the processing, thereby reducing the safety risks in the working process, reducing the frequent adjustment of the chassis position during the processing, saving adjustment time, and improving the processing efficiency;

[0052] When the staff needs to disassemble the vehicle chassis 13 between the placement table 32 and the square slide plate 34, in contrast to the above-mentioned movement process, the staff needs to first rotate the threaded convex ring 310 in the opposite direction through the anti-slip rod 311 to gradually increase the distance between the threaded convex ring 310 and the interference block 39, and the staff presses the pressing rod 37 into the inside of the columnar groove 36, and then the pressing rod 37 slides toward the bottom of the columnar groove 36, and the pressing rod 37 gradually compresses the second return spring 38, and the pressing rod 37 will drive the bottom interference block 39 to rotate into the inside of the columnar groove 36. When the interference block 39 is completely moved to the inside of the threaded groove column 35, the staff holds the arc handle 312 to move the threaded groove column 35 out of the placement table 32 and the square slide plate 34, and the placement table 32 and the square slide plate 34 lose the restrictions of the threaded convex ring 310 and the interference block 39, and thus the placement table 32 and the square slide plate 34 cannot fix the vehicle chassis 13, thereby achieving the purpose of quick disassembly. The vehicle chassis 13 is located between the placement table 32 and the square slide 34. The staff only needs to pass the threaded groove column 35 through the inside of the placement table 32 and the square slide 34, and then rotate the threaded convex ring 310 to shorten the distance between the threaded convex ring 310 and the resistance block 39, so as to quickly fix the vehicle chassis 13 through the placement table 32 and the square slide 34. When the staff needs to disassemble the vehicle chassis 13, they only need to rotate the threaded convex ring 310 in the opposite direction and press the pressing rod 37 into the threaded groove column 35. Then the pressing rod 37 will move the resistance block 39 to the inside of the threaded groove column 35, and finally pull the threaded groove column 35 out of the placement table 32 and the square slide 34, thereby achieving the purpose of quickly releasing the vehicle chassis 13. Compared with the traditional nut fixing method, the purpose of quickly disassembling the vehicle chassis 13 is achieved, the disassembly time is saved, the disassembly steps are simplified, the use of additional specific tools for disassembly and assembly is avoided, and the complexity of the operation is reduced.

[0053] When the chassis punching device needs to flip and punch the vehicle chassis 13, the staff first starts the driving device 22, and the driving device 22 starts to drive the threaded driving rod 23 fixedly connected thereto to start rotating. At this time, the threaded driving rod 23 first drives the lifting platform 24 to gradually move upward, and the lifting platform 24 drives the internal L-shaped rotating rod 27 to move upward synchronously, and the L-shaped rotating rod 27 drives the placement platform 32 and the square slide 34 to move upward synchronously through the triangular turntable 28, and the placement platform 32 and the square slide 34 drive the vehicle chassis 13 to move upward synchronously, and the placement platform 32 away from the side of the L-shaped rotating rod 27 moves upward synchronously along the L-shaped groove rod 31 through the vehicle chassis 13;

[0054] During the ascending process of the triangular turntable 28, the trigger rod 29 gradually contacts the top of the concave slide plate 213, and then the threaded driving rod 23 continues to drive the lifting platform 24 to move upward, at this time the trigger rod 29 contacts the top of the concave slide plate 213, and at this time the triangular turntable 28 rotates due to the contact between the trigger rod 29 and the concave slide plate 213, and then the triangular turntable 28 drives the L-shaped rotating rod 27 to rotate around the inside of the lifting platform 24, and at the same time, the L-shaped rotating rod 27 gradually stretches the first return spring 211 through the positioning block 210, and the end of the first return spring 211 away from the L-shaped rotating rod 27 drives the positioning block 210 to rotate around the distance increasing nail 25, and then the first return spring 211 begins to elastically contract, when the L-shaped rotating rod 27 contacts the limit column 26 again, at this time the L-shaped rotating rod 27 drives the placing platform 32 to rotate synchronously by 180 degrees through the triangular turntable 28, and the placing platform 32 and the square slide plate 34 rotate while driving the vehicle chassis 13 to rotate synchronously, thereby achieving the purpose of flipping the vehicle chassis 13;

[0055] Then the driving device 22 controls the threaded driving rod 23 to start to rotate in the opposite direction. At this time, the threaded driving rod 23 drives the lifting platform 24 to start to move downward, and the lifting platform 24 drives the L-shaped rotating rod 27 and the triangular turntable 28 to move downward synchronously. At this time, the trigger rod 29 at the bottom of the triangular turntable 28 will gradually contact the triangular reset block 214, and then the triangular reset block 214 is pushed by the trigger rod 29 to move horizontally, so that when the lifting platform 24 drives the L-shaped rotating rod 27 and the triangular turntable 28 to move upward again, the trigger rod 29 can contact the concave slide plate 213 again. Because the shape of the concave slide plate 213 is adapted to the shape of the trapezoidal groove block 212, the concave slide plate 213 is in the trapezoidal groove block 212. The internal horizontal lateral sliding of the groove block 212, through the setting of the flipping assembly, can achieve that during the rotation of the threaded drive rod 23, the threaded drive rod 23 will drive the lifting platform 24 to rise, and the rising of the lifting platform 24 will drive the trigger rod 29 to contact the top of the concave slide plate 213, thereby realizing the flipping of the vehicle chassis 13, thereby better controlling the angle and direction of the vehicle chassis 13 during the processing, improving the processing precision and accuracy, and at the same time, there is no need to use additional tools or equipment to flip the vehicle chassis 13, thereby improving the operating convenience of the chassis punching device, while improving the processing flexibility, optimizing the utilization of the working space, reducing the processing time and enhancing the operating convenience.

[0056] During the rotation of the threaded drive rod 23, the threaded drive rod 23 will drive the connecting block 42 to rotate through the rotating block 41. Since the connecting block 42 is made of aluminum alloy, the connecting block 42 is wear-resistant and hard. The connecting block 42 will drive the rotating column 43 to rotate synchronously. Then the rotating column 43 drives the power conversion rod 44 fixedly connected thereto to rotate. During the rotation of the power conversion rod 44, the two-way thread groove 45 will drive the diamond slide bar 46 to reciprocate and move horizontally. During the movement of the diamond slide bar 46, The square magnet block 47 synchronously moves back and forth laterally, and then the square magnet block 47 magnetically attracts the metal slide plate 48 to move back and forth laterally. Due to the arrangement of the strip-shaped limit plate group 411, the metal slide plate 48 cannot move to the outside of the punching device housing 11. Since a brush is arranged on the top of the cleaning plate 410, and the brush material of the cleaning plate 410 is set to polypropylene, the cleaning plate 410 can clean the vehicle chassis 13 during the process of the horizontal reciprocating movement, and the metal slide plate 48 drives the cleaning plate 410 to clean the vehicle chassis 13 through the third return spring 49 on the top;

[0057] When the chassis punching device flips and punches the vehicle chassis 13, the vehicle chassis 13 moves upward, and then the third return spring 49 gradually elastically stretches to push the cleaning plate 410 to always contact the bottom of the vehicle chassis 13. During the flipping of the vehicle chassis 13, the vehicle chassis 13 will contact the cleaning plate 410 and compress the third return spring 49 in the direction of the metal slide plate 48. After the vehicle chassis 13 is flipped over, the third return spring 49 still elastically stretches to push the cleaning plate 410 to always contact the bottom of the vehicle chassis 13, thereby achieving the purpose of real-time cleaning of the vehicle chassis 13.
