Description

Technical Field

[0001] This invention relates to the technical field of production lines, and in particular to a chassis grinding production line. Background Technology

[0002] Chassis and distribution boxes are typically assembled and welded from multiple sheet metal parts. After welding, the weld seams of the chassis and distribution boxes need to be ground. To achieve automated grinding of chassis and distribution boxes, Chinese invention patent application CN201910240067.5 proposes an automated grinding workstation for electrical cabinets. This grinding workstation uses the principle of current loop to calculate the grinding force output by the grinding head in real time. When the grinding force of the grinding head exceeds the preset range, the system controls the end of the robotic arm to make real-time adjustments, so that the grinding head restores the grinding force to the preset force range in an instant, thereby achieving constant force grinding. Through the special arrangement of the electrical cabinet processing station and the design of a specialized production line, the surface of the electrical cabinet to be processed can be continuously adjusted when the electrical cabinet passes through the corresponding flipping and lifting mechanism. Then, through the cooperation of the robotic arm and the grinding head, a constant grinding force is output in real time through the principle of current loop force control, realizing deburring, grinding, and polishing of various surfaces of the electrical cabinet, achieving full automation of the electrical cabinet grinding process.

[0003] However, the above-mentioned production line is not highly modular, making it inconvenient to flexibly adjust the functional modules of each workstation, making it difficult to achieve different working modes of the production line. Moreover, the number of grinding heads is relatively small, making it impossible to grind multiple surfaces and welds of the chassis and power distribution cabinet at the same time, resulting in low work efficiency. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a chassis grinding production line with high modularity, multiple grinding heads, and high efficiency, capable of simultaneously grinding multiple surfaces and welds of chassis and power distribution cabinets.

[0005] This invention discloses a chassis grinding production line, comprising a roller frame, a conveyor frame, and conveyor belts. Two roller frames are respectively disposed at both ends of the conveyor frame, and are used for feeding and discharging materials respectively. Two conveyor belts are installed parallel to each other on the conveyor frame. The line also includes multiple bases, multiple bases, multiple frames, multiple grinding modules (first and second), multiple bases respectively disposed on the left and right sides of the conveyor frame, multiple bases slidably mounted on the bases, and the bases can be close to or away from the conveyor frame. Each base has multiple module mounting positions for mounting different functional modules. Multiple frames are respectively mounted on the multiple module mounting positions. Grinding modules (first) are mounted on each of the multiple frames, and each grinding module (first) simultaneously grinds the upper surface of the chassis. Multiple grinding modules (second) are respectively mounted on the multiple frames, and each grinding module (second) simultaneously grinds the sides of the chassis. The positions of multiple racks on multiple bases are adjusted according to the specifications of the chassis, and the distance between the multiple racks and the conveyor frame is adjusted. During operation, the chassis is placed on the roller frame at the input end of the conveyor frame, and two conveyor belts transport the chassis to the roller frame at the output end of the rear conveyor frame. When the chassis reaches the space between multiple racks, the conveyor belts stop, and multiple grinding modules simultaneously grind the top surface of the chassis, while multiple grinding modules simultaneously grind the sides of the chassis. A robotic arm installed on the middle rack can flip the chassis for more comprehensive grinding. Alternatively, different functional modules can be replaced on multiple racks, and the different angles of multiple functional modules can be adjusted to achieve different working modes of the production line for different processing operations, such as welding, grinding, polishing, etc. Compared with existing technologies, this technology has a high degree of modularity, multiple grinding heads, and can simultaneously grind multiple surfaces and welds of the chassis and power distribution cabinet, resulting in high work efficiency.

[0006] Preferably, it also includes multiple motors and multiple lead screws. The multiple motors are respectively mounted on multiple bases, and the multiple lead screws are respectively rotatably mounted on multiple bases. The multiple lead screws are arranged perpendicularly to the conveyor frame. The output shafts of the multiple motors are respectively connected to the multiple lead screws. The multiple lead screws are respectively connected to the multiple bases through lead screw nuts. The motors drive the lead screws to rotate, and the lead screws drive the bases to move left and right on the bases through the lead screw nuts, thus making it suitable for chassis and distribution cabinets of different widths and having good versatility.

[0007] Preferably, it also includes multiple support brackets, two guide rails, and multiple shock-absorbing columns. The multiple support brackets are respectively installed on the left and right sides of the conveyor frame. The two guide rails are respectively installed on the multiple support brackets and are located on both sides of the conveyor frame. One end of the multiple shock-absorbing columns is connected to the two guide rails, and the other end of the multiple shock-absorbing columns is connected to both sides of the conveyor frame. The two guide rails limit and block the sides of the chassis and the power distribution cabinet. The multiple support brackets support the guide rails. The distance between the two guide rails and the conveyor frame is adjusted by the multiple shock-absorbing columns to prevent the chassis from falling off to the left or right, which is practical.

[0008] Preferably, the assembly also includes multiple second supports, multiple first pallets, multiple top plates, and multiple first cylinders. The first pallets are respectively mounted on the left and right sides of the conveyor frame via the multiple second supports. The multiple top plates are respectively slidably mounted on the first pallets. The fixed ends of the multiple first cylinders are respectively mounted on the first pallets, and the piston rods of the multiple first cylinders are respectively connected to the multiple top plates. When the machine box needs to be ground between the multiple frames, the piston rods of the multiple first cylinders push the multiple top plates towards the conveyor frame, so that the multiple top plates clamp the sides of the machine box, thereby correcting the machine box and preventing it from shifting. After the workpiece is clamped and fixed, the multiple first grinding modules and the multiple second grinding modules begin to work. Suction cups or electromagnets are installed on the multiple top plates to make the fixation more secure.

[0009] Preferably, the grinding module one includes a housing, a grinding motor, a drive wheel, a tension wheel, a roller frame, and a roller.

The roller frame is mounted inside the lower end of the housing, and the roller is rotatably mounted on the lower end of the roller frame. The lower part of the roller extends out of the lower part of the housing. The sanding belt is mounted on the drive wheel, tension wheel, and roller. When sanding the upper surface of the chassis, the drive wheel, tension wheel, and roller tighten the sanding belt. The sanding motor drives the drive wheel to rotate, which in turn drives the sanding belt to rotate. This allows the sanding belt below the roller to sand the weld seams on the upper surface of the chassis. The roller frame is slidably mounted on the lower part of the chassis and is elastically supported by a cylinder, making the contact between the sanding belt and the upper surface of the chassis more stable.

[0010] Preferably, it also includes a connecting plate, a vertical frame, and a lead screw assembly. The connecting plate is installed on the rear side of the housing, the vertical frame is installed vertically on the frame, the connecting plate is slidably installed on the vertical frame, and the lead screw assembly is installed on the vertical frame. The lead screw of the lead screw assembly is connected to the connecting plate through a lead screw nut. The rotation of the lead screw in the lead screw assembly drives the connecting plate and the housing to rise and fall along the vertical frame through the lead screw nut, thereby adjusting the height of the rollers. It is suitable for housings and distribution cabinets of different heights and has good versatility.

[0011] Preferably, it also includes multiple slide rails, multiple slide tables, and multiple push cylinders. The multiple slide rails are respectively mounted on multiple frames, the multiple slide tables are slidably mounted on the slide rails via multiple sliders, multiple uprights are respectively mounted on the multiple slide tables, and the fixed ends of the multiple push cylinders are respectively mounted on the multiple frames. The piston rods of the multiple push cylinders are respectively connected to the multiple slide tables. The piston rods of the multiple push cylinders extend or shorten, driving the multiple slide tables to move along the multiple slide rails, thereby causing the multiple housings and multiple rollers to move back and forth, achieving comprehensive grinding of the end face of the housing.

[0012] Preferably, the second grinding module includes a second housing, a second grinding motor, a second drive wheel, a second angle-adjusting motor, an eccentric wheel, a first push rod, a middle plate, a swing arm, a tie rod, a second wheel frame, two rollers, and a second tie rod. The second housing is horizontally installed in the middle of the frame. The second grinding motor is installed at the lower rear of the second housing via a motor mount. The second drive wheel is concentrically installed on the output shaft of the second grinding motor and is located inside the second housing. The second angle-adjusting motor is installed at the lower middle of the second housing. The second eccentric wheel is concentrically installed on the output shaft of the second angle-adjusting motor and is located inside the second housing. The rear end of the first push rod is eccentrically rotatably connected to the eccentric wheel, and the front end of the first push rod is rotatably connected to the left side of the middle plate. The right side of the middle plate is rotatably connected to the second housing. The rear end of the swing arm is rotatably connected to the front of the second housing. The rear end of the tie rod is rotatably connected to the right side of the middle plate, and the front end of the tie rod is rotatably connected to the rear end of the swing arm. The second wheel frame is rotatably installed at the front end of the swing arm. Two second rollers are rotatably installed on both sides of the second wheel frame. The front of roller two extends out from the front of housing two. The rear end of pull rod two is rotatably connected to the left end of the middle plate, and the front end of pull rod two is rotatably connected to the left end of wheel frame two. The sanding belt is fitted onto drive wheel two and two roller two. Drive wheel two and two roller two spread the sanding belt. The motor seat of sanding motor two is slidably set in housing two. The cylinder elastically pushes the motor seat of sanding motor two, so that the sanding belt is kept taut. Sanding motor two drives drive wheel two to rotate. Drive wheel two drives sanding belt to rotate and sand the side of the chassis. When the sanding angle needs to be adjusted, the angle adjustment motor drives the eccentric wheel to rotate a certain angle. The eccentric wheel pulls the middle plate to rotate a certain angle through push rod one. The right side of the middle plate pushes the swing arm to deflect a certain angle through the pull rod. At the same time, the left side of the middle plate pushes the wheel frame two to deflect a certain angle through pull rod two, thereby changing the orientation and angle of the sanding belt between the two roller two, adapting to the sanding of different angle sides of the chassis, and has good practicality.

[0013] Preferably, the assembly also includes multiple lifting platforms, multiple push cylinders, multiple slide rails, multiple lifting motors, and multiple lead screws. Multiple housings are slidably mounted on the multiple lifting platforms. The fixed ends of the multiple push cylinders are respectively mounted on the multiple lifting platforms. The piston rods of the multiple push cylinders are respectively connected to the multiple housings. The multiple slide rails are vertically mounted on the inner walls of the multiple frames. The multiple lifting platforms are slidably mounted on the multiple slide rails via multiple sliders. The multiple lifting motors are respectively mounted on the inner walls of the multiple frames. The multiple lead screws are vertically rotatably mounted on the inner walls of the multiple frames. The machine is connected to multiple lifting platforms via lead screws and nuts. The output shafts of multiple lifting motors are connected to multiple lead screws. The multiple lifting motors drive the multiple lead screws to rotate, and the multiple lead screws drive the multiple lifting platforms to rise or fall along multiple slide rails. This causes the grinding belt between the two rollers to rise and fall, grinding the vertical weld seams on the side of the machine casing. The piston rods of multiple push cylinders extend or shorten, pushing the multiple housings to move on the multiple lifting platforms. The distance between the multiple rollers and the conveyor frame is adjusted, making it suitable for machine casings of different widths and achieving automatic grinding of the sides of the machine casing.

[0014] Preferably, it also includes multiple suction pipes 1 and multiple suction pipes 2. The multiple suction pipes 1 are respectively installed on the outer walls of multiple housings 2, and the inlets of the multiple suction pipes 1 are respectively aligned with the multiple rollers 2. The multiple suction pipes 2 are respectively installed on both sides of the conveyor frame, and the inlets of the multiple suction pipes 2 are respectively aligned with the multiple rollers 1. The multiple suction pipes 1 collect the dust ground by the abrasive belt on the multiple rollers 2, and the multiple suction pipes 2 collect the dust ground by the abrasive belt on the multiple rollers 1, thereby reducing dust generated during grinding.

[0015] Compared with the prior art, the beneficial effects of this invention are as follows: Multiple racks are positioned on multiple bases according to the specifications of the chassis, and the distance between the multiple racks and the conveyor frame is adjusted. During operation, the chassis is placed on the roller frame at the input end of the conveyor frame, and two conveyor belts transport the chassis to the roller frame at the output end of the rear conveyor frame. When the chassis reaches the space between multiple racks, the conveyor belts stop, and multiple grinding modules simultaneously grind the upper surface of the chassis, while multiple grinding modules simultaneously grind the sides of the chassis. A robotic arm installed on the middle rack can flip the chassis for more comprehensive grinding. Alternatively, different functional modules can be replaced on multiple racks, and different angles of the multiple functional modules can be adjusted to achieve different working modes of the production line for different processing operations, such as welding, grinding, polishing, etc. Compared with the prior art, this invention has a high degree of modularity, multiple grinding heads, and can simultaneously grind multiple surfaces and welds of the chassis and power distribution cabinet, resulting in high work efficiency.

Detailed Implementation

[0029] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0030] Example 1

[0031] like Figures 1 to 4As shown, a chassis grinding production line includes a roller frame 1, a conveyor frame 2, and a conveyor belt 3. Two roller frames 1 are respectively disposed at both ends of the conveyor frame 2, and the two roller frames 1 are used for feeding and discharging materials respectively.

Multiple grinding modules 8 are respectively mounted on the multiple racks 6, which simultaneously grind the sides of the chassis. The system also includes multiple motors 9 and multiple lead screws 10. The motors 9 are respectively mounted on multiple bases 4, and the lead screws 10 are respectively mounted on multiple bases 4. The system is rotatably mounted on multiple bases 4. Multiple lead screws 10 are perpendicularly arranged to the conveyor frame 2. The output shafts of multiple motors 9 are respectively connected to the multiple lead screws 10. The multiple lead screws 10 are respectively connected to multiple bases 5 through lead screw nuts. It also includes multiple brackets 11, two guide rails 12, and multiple shock-absorbing columns 13. The multiple brackets 11 are respectively installed on the left and right sides of the conveyor frame 2, and the two guide rails 12 are respectively installed on the multiple brackets 11, located on both sides of the conveyor frame 2. Multiple shock-absorbing columns... One end of column 13 is connected to two guide rails 12 respectively, and the other ends of multiple shock-absorbing columns 13 are connected to both sides of the conveyor frame 2 respectively; it also includes multiple brackets 14, multiple pallets 15, multiple top plates 16 and multiple cylinders 17.

The piston rods of multiple cylinders 17 are connected to multiple top plates 16 respectively.

[0032] According to the specifications of the chassis, motor 9 drives lead screw 10 to rotate. Lead screw 10 drives base 5 to move left and right on base 4 through lead screw nut, adjusting the position of multiple frames 6 on multiple bases 5 and adjusting the distance between multiple frames 6 and conveyor frame 2, thus adapting to chassis and distribution cabinets of different widths. During operation, the chassis is placed on roller frame 1 at the input end of conveyor frame 2. Two guide rails 12 limit and block the sides of the chassis and distribution cabinet. Multiple brackets 11 support the guide rails 12. Multiple shock-absorbing columns 13 adjust the distance between the two guide rails 12 and conveyor frame 2 to prevent the chassis from falling to the left or right. Two conveyor belts 3 transport the chassis to roller frame 1 at the output end of conveyor frame 2. When the chassis reaches between multiple frames 6, the conveyor belts 3 stop, and the piston rods of multiple cylinders 17 move multiple top plates 16 towards the conveyor. The frame 2 is pushed, causing multiple top plates 16 to clamp the sides of the chassis, thus correcting the chassis and preventing it from shifting. After the workpiece is clamped and fixed, multiple grinding modules 1 7 and multiple grinding modules 2 8 begin to work. Suction cups or electromagnets are installed on the multiple top plates 16 to make the fixation more secure. Multiple grinding modules 1 7 simultaneously grind the upper surface of the chassis, and multiple grinding modules 2 8 simultaneously grind the sides of the chassis. A robotic arm is installed on the frame 6 in the middle, which can flip the chassis to achieve more comprehensive grinding. Alternatively, different functional modules can be replaced on multiple frames 6, and different angles of multiple functional modules can be adjusted to achieve different working modes of the production line to perform different processing operations, such as welding, grinding, polishing, etc. Compared with the existing technology, this technology has a high degree of modularity, multiple grinding heads, and can simultaneously grind multiple surfaces and welds of the chassis and power distribution cabinet, resulting in high work efficiency.

[0035] When grinding the upper surface of the chassis, the rotation of the lead screw in the lead screw assembly 26 drives the connecting plate 24 and the chassis 18 to rise and fall along the stand 25 via the lead screw nut, thereby adjusting the height of the roller 23. This is suitable for chassis and distribution cabinets of different heights. The drive wheel 20, tension wheel 21, and roller 23 tighten the grinding belt. The grinding motor 19 drives the drive wheel 20 to rotate, which in turn drives the grinding belt to rotate, so that the grinding belt under the roller 23 grinds the weld seams on the upper surface of the chassis. The grinding process involves sliding the roller frame 22 onto the lower part of the housing 18. The roller frame 22 is elastically supported by a cylinder, making the contact between the grinding belt and the upper surface of the housing more stable. The piston rods of multiple push cylinders 29 extend or shorten, driving multiple slides 28 to move along multiple slide rails 27, thereby moving multiple housings 18 and multiple rollers 23 back and forth to achieve comprehensive grinding of the end face of the housing. Multiple dust suction pipes 48 collect the dust ground by the grinding belt on the multiple rollers 23.

The angle-adjusting motor 33 is installed at the lower middle of the housing 30. The eccentric wheel 34... 4. Concentrically mounted on the output shaft of the angle-adjusting motor 33, the eccentric wheel 34 is located in the housing 2 30, the rear end of the push rod 1 35 is eccentrically rotatably connected to the eccentric wheel 34, the front end of the push rod 1 35 is rotatably connected to the left side of the intermediate plate 36, the right side of the intermediate plate 36 is rotatably connected to the housing 2 30, the rear end of the swing arm 37 is rotatably connected to the front side of the housing 2 30, the rear end of the pull rod 38 is rotatably connected to the right side of the intermediate plate 36, the front end of the pull rod 38 is rotatably connected to the rear end of the swing arm 37, the wheel frame 2 39 is rotatably mounted on the front end of the swing arm 37, and two rollers 2 40 are rotatably mounted on both sides of the wheel frame 2 39. The front part extends out from the front of the housing 2 30. The rear end of the pull rod 2 41 is rotatably connected to the left end of the middle plate 36, and the front end of the pull rod 2 41 is rotatably connected to the left end of the wheel frame 2 39. The sanding belt is fitted onto the drive wheel 2 32 and two rollers 2 40. It also includes multiple lifting platforms 42, multiple push cylinders 3 43, multiple slide rails 2 44, multiple lifting motors 45, and multiple lead screws 3 46. Multiple housings 2 30 are slidably mounted on multiple lifting platforms 42. The fixed ends of multiple push cylinders 3 43 are respectively mounted on multiple lifting platforms 42. The piston rods of multiple push cylinders 3 43 are respectively connected to multiple housings 2 30.

[0038] The second drive wheel 32 and two rollers 40 spread the sanding belt. The motor seat of the second sanding motor 31 is slidably mounted in the housing 30. The cylinder elastically pushes the motor seat of the second sanding motor 31, keeping the sanding belt taut. The second sanding motor 31 drives the second drive wheel 32 to rotate, which in turn drives the sanding belt to sand the side of the housing. When the sanding angle needs to be adjusted, the angle adjustment motor 33 drives the eccentric wheel 34 to rotate by a certain angle. The eccentric wheel 34 pulls the middle plate 36 to rotate by a certain angle via the push rod 35. The right side of the middle plate 36 pushes the swing arm 37 to deflect by a certain angle via the pull rod 38. At the same time, the left side of the middle plate 36 pushes the wheel frame 39 to deflect by a certain angle via the pull rod 41, thereby changing the angle of the two rollers. The orientation and angle of the abrasive belt between the rollers 40 are adapted to the grinding of different angles of the chassis side. Multiple lifting motors 45 drive multiple lead screws 46 to rotate, and multiple lead screws 46 drive multiple lifting platforms 42 to rise or fall along multiple slide rails 44, so that the abrasive belt between the two rollers 40 rises and falls, grinding the vertical weld seams on the side of the chassis. The piston rods of multiple push cylinders 43 extend or shorten, pushing multiple housings 30 to move on multiple lifting platforms 42, adjusting the distance between the multiple rollers 40 and the conveyor frame 2, which is suitable for chassis of different widths, realizing automatic grinding of the chassis side. Multiple dust suction pipes 47 collect the dust ground by the abrasive belt on the multiple rollers 40.

[0039] like Figures 1 to 12As shown, this invention discloses a chassis grinding production line. During operation, motor 9 drives lead screw 10 to rotate according to the chassis specifications. Lead screw 10 drives base 5 to move left and right on base 4 via lead screw nut, adjusting the positions of multiple frames 6 on multiple bases 5 and the distance between multiple frames 6 and conveyor frame 2. This is suitable for chassis and power distribution cabinets of different widths. The chassis is then placed on roller frame 1 at the input end of conveyor frame 2. Two conveyor belts 3 transport the chassis to roller frame 1 at the output end of conveyor frame 2. When the chassis reaches between multiple frames 6, the conveyor belts 3 stop. Then, lead screw assembly 26 operates, causing roller 23 to descend and contact the upper surface of the chassis. Grinding motor 19 drives drive wheel 20 to rotate, which in turn drives the grinding belt to rotate. The piston rod of push cylinder 29 extends... The retraction motor moves the sliding table 28 and the housing 18, causing the grinding belt under the roller 23 to grind the weld seam on the upper surface of the housing. At the same time, the piston rods of multiple push cylinders 43 extend, causing the grinding belt between the two rollers 40 to contact the side of the housing. The grinding motor 31 drives the drive wheel 32 to rotate, which in turn drives the grinding belt to grind the side of the housing. The angle adjustment motor 33 adjusts the orientation and angle of the grinding belt between the two rollers 40 to adapt to different angles of the housing side. Multiple lifting motors 45 raise or lower multiple lifting platforms 42, causing the grinding belt between the two rollers 40 to rise and fall, grinding the vertical weld seam on the side of the housing. Finally, after grinding, the two conveyor belts 3 transport the housing to the roller frame 1 at the output end of the conveyor frame 2.
