Description

A comprehensive processing device for supporting steel columns Technical Field

[0001] This invention relates to the field of skeleton vehicle processing technology, specifically a comprehensive processing device for supporting steel columns. Background Technology

[0002] The frame structure and strength of a skeleton vehicle determine its load-bearing capacity. Existing skeleton vehicles mostly employ rigidly fixed longitudinal and transverse beam structures. The longitudinal support steel columns serve as the main load-bearing structure, running from front to back, while the transverse beams are typically fixed between two longitudinal beams according to design requirements, forming a grid-like support structure. To increase the strength and rigidity of the frame structure, double-layer channel steel main and auxiliary support steel column structures have been applied in some medium and heavy-duty vehicles both domestically and internationally in recent years. The combination of side beams and riveted structures to fix the transverse beams is a common form used in many frames. The double-layer longitudinal beams are also fixed with bolts. In practical use, the double-layer channel steel structure significantly improves the support strength. However, because the area near the riveting points and the bolt assemblies bear a large load, the requirements for the connection parts are very high. If the positioning and fixing of the double-layer channel steel is inaccurate, stress will remain at the connection point. When under load, this will cause uneven force transmission in the connection part, leading to premature fracture. Adding multiple layers would increase the weight of the entire vehicle and the operating costs. Therefore, improving the processing precision of double-layer beams is the key to the load strength and reliability of the frame vehicle. Summary of the Invention

[0003] The purpose of this invention is to provide a comprehensive processing device for supporting steel columns, which can achieve high-precision insertion and processing of double-layer supporting steel column structures, thereby obtaining supporting beams with uniform load-bearing capacity and high strength.

[0004] To achieve the above objectives, the present invention employs the following technical solution:

[0005] A comprehensive processing device for supporting steel columns includes a first positioning fixture, a second positioning fixture, and a moving positioning mechanism;

[0006] The first positioning fixture is configured to fix the outer channel steel;

[0007] The second positioning fixture is arranged in the same direction at one end of the first positioning fixture, and is configured to support the inner channel steel and make the position of the inner channel steel correspond to the inner cavity of the outer channel steel.

[0008] The mobile positioning mechanism includes multiple sets of mounting frames with horizontal linear travel. The horizontal linear travel of the mounting frames covers both ends of the first positioning fixture and the second positioning fixture. The top and bottom sides of the mounting frames are respectively provided with mounting shafts in the same direction as their travel. A motor-driven bushing is rotatably sleeved on the mounting shaft. A connecting rod extending radially is fixed on the bushing. A swing shaft driven by a motor is rotatably connected to the connecting rod. A support roller is fixed to the end of the swing shaft. The swing shaft has a swing travel based on the rotation of the bushing. The starting point of the swing travel is when the swing shaft is in a vertical state. The ending point of the swing travel is when one end of the support roller of the swing shaft is inclined towards the second positioning fixture, and the two support rollers respectively abut against the upper and lower concave corners of the inner channel steel.

[0009] The first positioning fixture includes an upright support plate, on which a horizontally extending first track mechanism is provided. The first track mechanism outputs a first slide table, which has a linear sliding stroke along the length of the support plate. A drilling device is mounted on the first slide table, and the drilling device includes a drill bit with a vertical extension stroke relative to the support plate.

[0010] The support plate is provided with multiple sets of clamps. Each clamp includes a fixed seat that is symmetrically fixed on the support plate relative to the first track mechanism. A cylinder is installed on the fixed seat. One end of each cylinder is provided with a cylinder rod that is telescopically coordinated with it. A clamping plate is fixed to the inner end of the cylinder rod. The clamping plate is L-shaped with a right-angle bend.

[0011] The second positioning fixture includes a conveying mechanism and a second track mechanism. The conveying mechanism includes a frame, on which unpowered conveying rollers are rotatably mounted.

[0012] The second track mechanism is located on one side of the conveying mechanism. The second track mechanism extends in the same direction and at the same height as the first track mechanism. The second track mechanism includes a second slide with a horizontal linear travel. Several sets of positioning frames are fixed on the second slide. Vertical axles are installed on the positioning frames. Multiple positioning rollers are rotatably installed on each axle. The positioning rollers contact the outer side of the inner channel steel. When the bottom side of the channel steel falls on the conveying roller, the inner channel steel corresponds to the inner cavity of the outer channel steel fixed on the first positioning fixture.

[0013] The mobile positioning mechanism includes a third track mechanism that extends parallel to and at the same height as the first track mechanism. The third track mechanism outputs a third slide table, and the linear sliding stroke of the third slide table can cover the area of ​​the first track mechanism and the second track mechanism. The mounting bracket is fixedly installed on the third slide table.

[0014] One end of the bushing is fixed with a driven pulley coaxial with it.

[0015] The mounting frame has an upper gear and a lower gear mounted side by side in the middle, meshing with each other. The upper gear has an upper pulley coaxial with it, and the lower gear has a lower pulley coaxial with it. The upper pulley is driven by a belt to the driven pulley located above it, and the lower pulley is driven by a belt to the driven pulley located below it. The mounting frame has a motor box, and a first stepper motor is installed in the motor box. The output shaft of the first stepper motor has a drive gear that meshes with the upper gear or the lower gear.

[0016] The swing shaft is provided with a driven gear at one end adjacent to the connecting rod, and a second stepper motor is fixed on the bushing. The output shaft of the second stepper motor is provided with a driving gear that meshes with the driven gear.

[0019] This device enables the automated processing of double-layer channel steel support columns, ensuring stable and tight splicing of the inner and outer channel steel layers. It also provides high precision in hole alignment after installation, evenly distributing load at the installation location, reducing breakage issues, and improving the overall strength and load-bearing capacity of the frame vehicle.

It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined in this application.

[0031] Unless otherwise specified, the instruments, reagents, and materials used in the following embodiments are all conventional instruments, reagents, and materials already available in the prior art and can be obtained through legitimate commercial channels. Unless otherwise specified, the experimental methods and detection methods used in the following embodiments are all conventional experimental methods and detection methods already available in the prior art. Examples:

[0032] This example demonstrates a comprehensive fabrication system for the supporting steel columns acting as longitudinal beams. It primarily involves the assembly and drilling of channel steel. The main structure includes:

[0033] First positioning fixture, second positioning fixture, and mobile positioning mechanism

[0034] 1. First positioning fixture

[0035] The first positioning fixture includes a support plate 1 fixedly installed in the workshop. The support plate 1 is vertically fixed. A first track mechanism 2 extending horizontally is provided on one vertical end face of the support plate 1. A first slide 3 is output on the first track mechanism 2. The first slide 3 has a linear sliding stroke along the length direction of the support plate 1. A drilling device 4 is installed on the first slide 3. The drilling device 4 is a drilling machine commonly used in the prior art, including a retractable drill bit. The length direction and the retraction direction of the drill bit are perpendicular to the support plate 1.

[0036] The support plate 1 is equipped with multiple sets of clamps, which are used to clamp and fix the outer channel steel at no less than two points. In this example, at least one set of clamps is set at each end of the support plate 1. Each clamp includes a fixing seat 5 symmetrically fixed to the support plate 1 relative to the first track mechanism 2. A cylinder 6 is installed on the fixing seat 5. The two cylinders 6 have cylinder rods that telescopically cooperate with each other at opposite ends. A clamping plate 7 is fixed to the inner end of the cylinder rod. The clamping plate 7 is an L-shape with a right-angle bend, which is used to cooperate with the right angle of the outer channel steel to position it. The two clamping plates 7 are symmetrically arranged above and below the first track mechanism 2. Based on the synchronous drive of the cylinders 6, the clamping plates 7 have a reciprocating stroke that moves in opposite directions relative to the first track mechanism 2, thereby clamping and fixing the outer channel steel located in the middle.

[0037] 2. Second positioning fixture

[0038] The second positioning fixture includes a conveying mechanism 8 and a second track mechanism 10;

[0039] The conveying mechanism 8 and the second track mechanism 10 are arranged in the same direction and parallel to each other, and their extension directions are in the same direction as the support plate 1.

[0040] The conveying mechanism 8 uses a non-powered roller conveyor, including a frame. One end of the frame is positioned close to one end of the support plate 1 to facilitate auxiliary support for the inner channel steel during its movement from the inner channel steel to the outer channel steel. Conveying rollers 9 are rotatably mounted between the frames. The bearing-mounted conveying rollers 9 rotate flexibly and smoothly, both supporting the channel steel and facilitating its conveying.

[0041] The top side of the circumference of the conveying roller 9 is tangent to the bottom inner wall (the upper end face of the lower leg) of the outer channel steel held on the clamp, so the inner channel steel on the conveying roller 9 can be smoothly inserted into the outer channel steel.

[0042] The second track mechanism 10 is located on one side of the conveying mechanism 8. The extension direction of the second track mechanism 10 is the same as that of the support plate 1. The length of the second track mechanism 10 is longer than that of the channel steel, which facilitates the independent loading and unloading of the first positioning fixture and the second positioning fixture.

[0043] The second track mechanism 10 is supported and fixed by a support frame. The second track mechanism 10 outputs a second slide 11. The second slide 11 has a horizontal linear sliding stroke in the same direction as the first slide 3. Based on its sliding stroke, the second slide 11 has a positioning stroke position and an auxiliary stroke position. The positioning stroke position is when the second slide 11 is located in the middle position of the conveying mechanism 8. The auxiliary stroke position is when the second slide 11 is located at one end of the conveying mechanism 8 near the first positioning fixture.

[0044] Two or three sets of positioning frames 12 are fixed on the second slide table 11. The positioning frame 12 is a "[" shaped frame structure. An upright wheel axle 13 is fixedly installed on the positioning frame 12. Each positioning frame is equipped with three equidistantly arranged wheel axles 13. Two or more positioning rollers 14 are rotatably installed on the wheel axle 13. The swing shaft 28 of the positioning roller 14 is also upright. The circumferential surface of the positioning roller 14 away from the second slide table 11 is tangent to the upright inner wall (inner end face of the waist) of the outer channel steel clamped on the fixture.

[0045] Based on the support and positioning of the bottom surface of the inner channel steel by the conveying roller 9, and combined with the blocking and positioning of the outer waist of the inner channel steel by the positioning roller 14, the inner channel steel is fed onto the conveying roller 9, and the waist of the channel steel is pushed to contact the roller, so that the inner channel steel can be positioned so that it can be inserted into the outer channel steel fixed by the clamp along the length direction.

[0046] 3. Mobile positioning mechanism

[0047] The moving positioning mechanism is located on the side of the conveying mechanism 8 away from the second track mechanism 10. The moving positioning mechanism includes a third track mechanism 15 extending parallel to and at the same height as the first track mechanism 2. The third track mechanism 15 outputs a third slide table 16. The length of the third track mechanism 15 covers both ends of the first track mechanism 2 and the second track mechanism 10, allowing the linear sliding stroke of the third slide table 16 to cover the areas of the first track mechanism 2 and the second track mechanism 10. This enables the inner channel steel to be dragged from the second positioning fixture to the position of the first positioning fixture, achieving the splicing and assembly of the inner and outer double-layer channel steel.

[0048] The first track mechanism 2, the second track mechanism 10, and the third track mechanism 15 can adopt the same track structure. Depending on the travel length without stopping operation, they include linear tracks and racks of different lengths. The linear tracks and racks are arranged side by side. Since most of them are load-bearing components, it is recommended that the track mechanism adopt a double-layer upper and lower track layout, that is, two linear tracks are symmetrically arranged above and below the rack. Sliders are slidably engaged on the linear tracks. The sliders of different track mechanisms are respectively installed on the first slide table 3, the second slide table 11, and the third slide table 16 to guide the sliding direction.

[0049] The first slide 3, the second slide 11, and the third slide 16 are each equipped with a traveling gear that is driven to rotate by a motor. The traveling gear meshes with a rack to drive the slide.

[0050] The second track mechanism 10 and the third track mechanism 15 can be fixedly installed in the workshop using conventional support frames.

[0051] Three third slides 16 are provided, and each of the three third slides 16 can independently control its position on the third track mechanism 15 based on its own traveling gear. They are independent of each other. Based on the independence of the three third slides 16, the coordination relationship under multiple processes is realized.

[0052] The third slide 16 is provided with a mounting bracket 17. The outer side of the mounting bracket 17 is fixed to the third slide 16. The mounting bracket 17 is provided with a motor box 18. The first stepper motor is installed in the motor box 18. The output shaft of the first stepper motor in the motor box 18 passes through the motor box 18 and is equipped with a drive gear 19.

[0053] The mounting frame 17 has slotted frames 22 on its top and bottom sides, which are symmetrically arranged relative to the third track mechanism 15. The opening of the slotted frame 22 is located on the side closer to the conveying mechanism 8. A mounting shaft 23 is fixed at the opening of the slotted frame 22. The axial direction of the mounting shaft 23 is the same as that of the third track mechanism 15. A bushing 24 is rotatably mounted on the mounting shaft 23. One end of the bushing 24 is provided with a driven pulley 25. The middle part of the mounting frame 17 is rotatable. The device is equipped with an upper gear 20 and a lower gear 21, which mesh with each other. The upper gear 20 has an upper pulley coaxial with it, and the lower gear 21 has a lower pulley coaxial with it. The upper pulley is driven by the driven pulley 25 located above it through a belt 26, and the lower pulley is driven by the driven pulley 25 located below it through the belt 26. The drive gear 19 meshes with the lower gear 21, thereby realizing the drive control of the two bushings 24 to rotate in opposite directions.

[0054] A connecting rod 27 with a T-shaped structure is fixed to the bushing 24. A swing shaft 28 is rotatably sleeved at the end of the connecting rod 27. One end of the swing shaft 28 is sleeved at the end of the connecting rod 27, and the two are rotatably connected by a bearing. A support roller 29 is fixed at the end of the swing shaft 28 away from the bushing 24. A driven gear 30 is provided at the end of the swing shaft 28 adjacent to the connecting rod 27. A second stepper motor is fixed to the bushing 24. A driving gear 31 meshes with the driven gear 30 on the output shaft of the second stepper motor, thereby driving the circumferential rotation of the swing shaft 28 and further controlling the rotation of the support roller 29.

[0055] Based on the rotation of the bushing 24 driven by the first stepper motor, the swing shaft 28 has a swing stroke, which includes a range of strokes that allow the swing shaft 28 to swing at a 45-degree angle (not limited to this example, but can also be other acute angles).

[0056] When the swing shaft 28 is at the starting point of the swing stroke, the two swing shafts 28 are coaxial and vertical, and the support roller 29 is far away from and does not contact the inner channel steel. When the swing shaft 28 is at the ending point of the swing stroke, one end of the support roller 29 of the swing shaft 28 is inclined at about 45 degrees towards the conveying mechanism 8. The upper support roller 29 abuts against the upper inner corner of the inner channel steel, and the lower support roller 29 abuts against the lower inner corner of the inner channel steel. The two sides of the circumference of the support roller 29 have a first rounded corner and a second rounded corner, respectively. The first rounded corner of the support roller 29 contacts the inner side of the channel steel leg, and the second rounded corner of the support roller 29 contacts the inner side of the channel steel waist.

[0057] Therefore, when the swing shaft 28 is at the end of its stroke, the upper and lower support rollers 29 are tightly abutting against the two inner corners of the inner channel steel. The support rollers 29 are rubber wheels with high frictional resistance. When the mounting frame 17 moves horizontally, under the support and rolling cooperation of the conveyor rollers 9, the support rollers 29 drive the inner channel steel to move towards the first positioning fixture. At the same time, when the support rollers 29 are driven to rotate by the second stepper motor, they can have the effect of rubbing the inner channel steel to move. This achieves two forms of driving the channel steel to move.

[0058] Based on the above structure, the following processing steps are performed:

[0059] S1, Load the first positioning fixture and clamp and fix the outer channel steel through the clamps at both ends;

[0060] S2, all three mounting brackets (third slides) are moved to the side close to the first positioning fixture, making room for the loading of the second positioning fixture. The second slide is located at its positioning stroke position, loading the second positioning fixture, placing the inner channel steel on the conveying roller, and making the outer waist end face of the inner channel steel contact the circumferential surface of all positioning rollers.

[0061] S3, with the swing shaft in a vertical position at the starting point of its stroke, start the three mounting brackets to move independently and synchronously toward the second positioning fixture. When the mounting bracket in the middle corresponds to the position of the second slide, start the swing stroke of the swing shaft to tilt and swing the swing shaft toward the inner channel steel until the support rollers are tightly against the upper and lower inner corners of the inner channel steel.

[0062] S4, keep the support roller in contact with the inside corner of the channel steel, and simultaneously start the second and third slides to move synchronously towards the first positioning fixture. The support roller drives the inner channel steel to move synchronously. The second slide moves to near the support plate and stops at its auxiliary stroke position. The three third slides move to the middle of the first track mechanism and then stop.

[0063] S5, start the support roller to rotate, and continue to finely adjust the inner channel steel towards the direction of insertion into the outer channel steel, until the inner and outer channel steels are fully inserted and aligned at both ends.

[0064] The alignment determination can be achieved by manually observing and manipulating the support rollers, or by installing a position sensor at the end of the first positioning fixture away from the second positioning fixture to identify and provide feedback on the position of the inner channel steel.

[0065] The positioning rollers on the synchronously moving second slide assist in positioning during the insertion process.

[0066] The three third mounting brackets are started and move synchronously toward the first positioning fixture.

[0067] S6, the two mounting brackets (third slides) at both ends move in opposite directions to near the two ends of the inner channel steel and then stop. During the movement, the rollers on each mounting bracket rotate in coordination with the travel speed, so that the surface of the rollers rolls in the same direction as the surface of the inner channel steel without rubbing against each other and without affecting the position of the inner channel steel. Through the mounting brackets at both ends of the inner channel steel, the inner channel steel is pressed against it, so that the inner channel steel is only in contact with the outer channel steel.

[0068] S7, the first slide table is started to move from one end of the first track mechanism to the other. During the movement, it stops at the preset drilling position. At the same time, the middle mounting frame is started to move and stop synchronously with the first slide table. During the movement, its support rollers rotate adaptively with the direction and speed of movement. When the first slide table stops, the drill bit is started to drill the double-layer channel steel. At the same time, the middle mounting frame is positioned at the corresponding drilling position and stops. Its support rollers on the other side of the drilling position provide auxiliary clamping to the upper and lower parts of the drilling position, so that the inner channel steel at the drilling position is only in contact with the outer channel steel. This makes the double-layer structure stable during the drilling process, ensuring the height of the drilling is corresponding. As a result, after the bolts are installed, the hole correspondence at each installation position is highly accurate, there is no uneven stress, and the load can be evenly borne, avoiding instability at the connection of the double-layer support structure.

[0069] In addition, during step s4, the inner channel steel is inserted into the outer channel steel under the drive of the support roller. The support roller and the positioning roller on the second slide plate clamp and position the inner channel steel on both the inner and outer sides, so that it is accurately matched with the inner wall position of the outer channel steel.

[0070] When the channel steels come into contact, although there is auxiliary support from the conveyor rollers and the support rollers for their weight, friction is still inevitable between the contact surfaces of the channel steels. Especially after the inner channel steels are separated from the conveyor rollers, the friction between the channel steels increases, affecting the synchronicity of the support rollers driving the inner channel steels, thus resulting in low precision in the insertion. Therefore, when the three third slides move to the middle of the first track mechanism (i.e., the outer channel steel), the inner channel steels may still have a slight misalignment with the outer channel steels. However, S5, through the cam, can fine-tune the position of the inner channel steels, aligning the ends of the inner and outer channel steels and ensuring the precision of the insertion.

[0071] Based on this equipment, combined with the control steps described above, high-precision splicing and drilling of double-layer channel steel can be achieved. The hole correspondence accuracy of the double-layer structure after installation is high, and the load is evenly distributed after bolt riveting, avoiding uneven force transmission caused by adverse stress and torque, reducing beam breakage problems, and improving the overall strength and load-bearing capacity of the frame vehicle.

[0072] The second slide has a horizontal linear sliding stroke in the same direction as the first slide. Based on its sliding stroke, the second slide has a positioning stroke position and an auxiliary stroke position. The positioning stroke position is when the second slide is located in the middle of the conveying mechanism, and the auxiliary stroke position is when the second slide is located at the end of the conveying mechanism near the first positioning fixture.
