Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, in particular to a welding platform with longitudinal and transverse conveying and clamping functions. Background Art

[0002] Dump truck wall panels feature a wide range of individual lengths and are commonly used on trucks and railroad freight cars. These panels incorporate multiple reinforcing ribs to enhance their strength and load-bearing capacity. To achieve removable connections to the vehicle, these panels require a connecting structure. Consequently, the entire dump truck wall panel manufacturing process involves numerous steps, requiring a large and cumbersome processing platform. To improve production efficiency, automated welding platforms, using robotics to coordinate welding processes, have become a key research focus in the industry.

[0003] However, the existing automated welding platform for dump truck wall panels has the following problems: when a single wall panel is transmitted, it is subject to great resistance. If a belt is used, there will be problems of slipping or the wall panel cannot be driven due to its heavy weight. Therefore, conventional transmission adopts a chain structure transmission; in order to realize the chain transmission, a jacking frame needs to be installed on the platform. Because the use of the chain itself needs to take into account labor saving, energy saving and force requirements, the jacking frame needs to be set on the platform. During the transmission process, it is inevitable that it will come into contact with the dump truck wall panel, causing extrusion friction, serious damage to the surface of the workpiece, and the quality of the workpiece cannot be guaranteed; on the existing automated welding platform, each workstation needs to be precisely positioned to facilitate the cooperation with the robot to complete welding, spraying and other processes, but there will be friction during the chain transmission process, and the chain itself is relatively soft, which leads to misalignment of force transmission. Therefore, the existing automated welding cannot actually achieve precise positioning in one step, but is fine-tuned and calibrated during the transmission process, which directly leads to the need to align and position the dump truck wall panels formed by the combination of multiple unit links with a large length range and repetition during the welding process, which wastes a lot of time and has poor positioning accuracy.

[0004] In order to leave enough operating space for robots to perform processes such as spraying and welding, the base of the existing welding platform has a large opening panel to facilitate personnel maintenance. However, the large opening structure makes it easy for personnel to step on air and get injured during operation, which reduces safety.

[0005] Therefore, the existing automated welding platform needs to be modified in many aspects to address the above problems. Summary of the Invention

[0006] The present invention aims to provide a welding platform with longitudinal and transverse conveying and clamping functions, which is used to solve the technical problems of the existing dump truck wall panel welding platform that is prone to displacement during transportation, large workpiece positioning errors, and more friction between the jacking frame and the workpiece contact surface, which reduces the quality of the workpiece.

[0007] The basic solution provided by the present invention is: a welding platform with longitudinal and transverse conveying and clamping functions, comprising a base with a strip structure, a clamping device mounted on the base, a gantry, a plurality of transverse subunits and a plurality of longitudinal subunits;

[0008] The transverse subunit includes a transverse transmission device and a first vertical lifting device installed on the transverse transmission device; the transverse transmission device includes a transverse subunit frame, and a plurality of longitudinal rollers installed on the transverse subunit frame and uniformly distributed along the transverse direction;

[0009] The longitudinal subunit includes a longitudinal transmission device and an oblique lifting device installed on the longitudinal transmission device; the longitudinal transmission device includes a longitudinal subunit frame, and four transverse rollers installed on the longitudinal subunit frame and arranged in a matrix along the longitudinal and transverse directions; a double-side sprocket, a main transmission shaft, a telescopic universal joint, a motor, a reducer and an output shaft are installed between the two transverse rollers arranged along the transverse direction; a single-side sprocket is installed at one end away from each other on the two transverse rollers arranged along the transverse direction, and is located above the double-side sprockets; the oblique lifting device is located below the two transverse rollers arranged along the longitudinal direction, and includes a support seat 1, a support seat 2, a movable connecting piece, a lifting cylinder and a connecting head; the support seat 1 and the support seat 2 are connected to the longitudinal subunit frame through a movable connecting piece; the lifting cylinder is connected between the longitudinal subunit frame and the support seat 2 through a connecting head; the support seat 1 and the support seat 2 are connected to the base;

[0010] The pressing device includes a pressing plate; the base includes a panel; and the panel is provided with a strip-shaped hole for installing the pressing plate.

[0011] The working principle and advantages of this invention are: This solution achieves minimal cost transformation and provides a new integrated welding, maintenance, transmission, and pressing processing platform. Existing automated welding platforms focus on processing with robots and the processing itself, while this solution considers the comprehensive full-cycle form of processing and operation and maintenance throughout the entire welding platform life cycle. Therefore, the overall structure is designed from a multi-dimensional and multi-process perspective.

[0012] Specifically, this platform enables automated transport and clamping of wall panels from dump trucks, which are then combined with welding robots for automated welding. Compared to existing technologies, this solution breaks through the existing single, unified transport method by specifically configuring the conveying and lifting devices for the longitudinal and transverse subunits. Instead, it proposes differentiating the conveying and lifting functions of each subunit. This interaction improves positioning accuracy during transport. Furthermore, based on conventional clamping devices, the special configuration of the pressure plate and mounting position enhances stability and precision during welding.

[0013] Specifically, the horizontal and vertical conveying of the workpiece are realized through the horizontal conveying device and the vertical conveying device, and roller transmission is adopted. The distribution position, wheel diameter, height and arrangement direction of the horizontal and vertical transmission of the rollers, as well as the realization of the inclined lifting function, control of a reasonable transmission speed can ensure that the connection structure will not be compressed during the transmission of the dump truck wall panel, and will not affect the shape and force of the wall panel connection structure, and will not affect the force of the wall panel, thereby ensuring the structural quality of the connection. During the transportation process, the friction is small, there will be no scratches, and the surface quality is guaranteed. Compared with the prior art, the structure of the chain transmission for horizontal transmission reduces the contact area with the workpiece, reduces the failure points, reduces the degree of friction on the surface of the workpiece, and improves the continuity of the welding process and the workpiece processing quality. According to the comprehensive design of the structure of this scheme, each subunit, on the basis of meeting the functional requirements such as the requirements of robot processing, the position of the center of gravity of horizontal and vertical transmission, and the size of rollers, occupies the smallest area, has good platform integration, and has a compact structure.

[0014] The longitudinal conveying is an electric transmission function, and the transverse conveying is an unpowered transmission function, which takes into account the energy consumption of the system and the high efficiency of manual positioning assistance. Because in actual production, it is found that the distance is long during longitudinal and transverse conveying, and the operator-assisted conveying is difficult and risky, so a small number of rollers + electric transmission method is adopted to achieve efficient conveying, while the distance is short during transverse conveying, and the operator-assisted conveying is highly operable, so a large number of rollers + unpowered transmission method is adopted to directly push the conveying, which can reduce the energy consumption of the system and quickly align the positions; the longitudinal lifting is an oblique lifting method, which is in line with the characteristics of the longer workpiece size. The upward creative use of the inclined rising method and the setting of the inclination angle height can ensure the appropriate transmission force, improve the stability of the conveying process, avoid the displacement of the workpiece, reduce the positioning error, and improve the positioning accuracy; while the horizontal lifting adopts the vertical lifting method, in order to ensure the appropriate positioning accuracy, the vertical lifting distance is short, and it can be quickly put into place under the action of manual push; the clamping device is installed through the strip holes added on the panel by adding a pressure plate, and the pressure plate can be moved along the strip holes to adapt to the enhanced clamping function of wall panels of different sizes, reducing the blind spots where the gantry cannot clamp, and making the adjustment of the clamping function more flexible and changeable.

[0015] Furthermore, the base also includes a plurality of stops evenly distributed on one longitudinal side of the panel and at the rear end of the base along the transmission direction.

[0016] Beneficial effect: Through longitudinal and lateral support, physical positioning can be achieved and positioning accuracy can be improved.

[0017] Furthermore, it also includes an end sub-unit; the end sub-unit includes an end transmission device and a second vertical lifting device; the end transmission device includes an end frame and an end roller installed on the end frame; the first vertical lifting device and the second vertical lifting device both include vertical cylinders respectively installed under a number of longitudinal rollers and end rollers.

[0018] Beneficial effects: The end and lateral transmission adopt the same non-powered transmission method and vertical lifting function, which can simplify the system structure. At the same time, the end transmission device mainly plays an auxiliary role in supporting the product after it is raised when the product is loaded, and adopts a non-powered method to effectively reduce the energy consumption of the system.

[0019] Furthermore, guide columns are installed on both sides of the vertical cylinder.

[0020] Beneficial effects: Assists in vertical lifting and improves stability during the lifting process.

[0021] Furthermore, the panel is provided with a plurality of through holes corresponding to the positions of the rollers.

[0022] Beneficial effect: The panel only has holes at the corresponding positions of the roller, reducing the risk of operators stepping on empty space.

[0023] Furthermore, it also includes a plurality of pneumatic control valves, which are respectively installed at the end position of the base with a stop end, and are used to perform group control operation according to a preset control method.

[0024] Beneficial effect: can reduce the waste of compressed air.

[0025] Furthermore, the lifting cylinder is connected between the longitudinal sub-unit frame and the support seat 2 through a connecting head. The end of the lifting cylinder is equipped with a connecting head, which is connected to the connecting head on the longitudinal sub-unit frame through a pin shaft; the tail of the lifting cylinder adopts a rear flange, which is connected to the support seat 2 through a pin shaft.

[0026] Beneficial effect: It makes the activities and connections during transportation smoother.

[0027] Furthermore, the clamping device also includes a plurality of clamping cylinders installed on the gantry frame in the transverse direction. The clamping cylinder composition includes a cylinder, a pressure head installed at the lower end of the cylinder, a cylinder seat installed above the cylinder, and a plurality of wheel pairs installed on the cylinder seat.

[0028] Beneficial effects: Cooperate with the pressing plate to enhance the pressing function, and the pressing position can be flexibly adjusted to adapt to wall panels of different models and sizes.

[0029] Furthermore, a positioning bar is provided on the gantry; the positioning bar is located between the plurality of wheel pairs and is used for sliding positioning.

[0030] Beneficial effect: improving the displacement accuracy of the pressing device during sliding and avoiding deviation. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following is a further detailed description through specific implementation methods:

[0040] The symbols in the drawings of the specification include: base 1, panel 11, strip hole assembly 12, first strip hole 121, second strip hole 122, horizontal stop 13, longitudinal stop 14, horizontal subunit 2, horizontal subunit frame 21, longitudinal roller 22, bearing seat mounting seat 23, bearing seat 24, bearing seat positioning block 25, longitudinal subunit 3, longitudinal subunit frame 31, horizontal rollers 32 arranged in the transverse direction, double-side sprockets 33, main transmission shaft 3 4.

[0041] The embodiment is basically as shown in the attached Figure 1 As shown: A welding platform with longitudinal and transverse conveying and clamping functions, including a base 1 with a strip structure and a clamping device 5 installed on the base 1, a gantry 4, a plurality of transverse subunits 2 and a plurality of longitudinal subunits 3.

[0042] In order to better describe the horizontal and vertical, such as Figure 1 As shown, the direction of the arrow is defined as the longitudinal transmission direction, one end of the base 1 pointed by the arrow is the end of the base 1, and the other end is the end head of the base 1. The end of the base 1 can be connected to another welding platform to extend the platform in combination; the long side direction of the base 1 is longitudinal, and the two long sides are defined as one longitudinal side and the other longitudinal side respectively; the short side direction of the base 1 is transverse; the transverse roller is defined as a roller with a transverse long axis direction, and the longitudinal roller 22 is defined as a roller with a longitudinal long axis direction. The longitudinal roller 22 and the transverse roller have the same structure and installation method, but the long axis direction is different when arranged; the unit of the dimensional data in the drawings is mm.

[0043] The base 1 includes a panel 11, which has a plurality of strip hole groups 12 formed on the panel 11. The panel 11 is located between the rollers of the longitudinal sub-unit 3 and is used to install the pressure plate 55 of the clamping device 5. The strip hole group 12 includes a first strip hole 121 and a second strip hole 122. The length of the first strip hole 121 is greater than the second strip hole 122. The first strip hole 121 has a first length, so that the distance from the first strip hole 121 to the second strip hole 122 can be flexibly adjusted to adapt to pressure plates 55 of different models and sizes. In this embodiment, the length of the first strip hole 121 is controlled at 850-950mm, and the length of the second strip hole 122 is controlled at 70-90mm, which matches the size of most existing dump truck wall panels and achieves effective clamping. The panel 11 also has a plurality of through holes corresponding to the positions of the rollers 54, and the rest is a closed solid panel 11, which avoids the danger of the operator stepping on the air and improves safety.

[0044] like Figure 2 As shown, the base 1 also includes a plurality of stops evenly distributed on one longitudinal side of the panel 11 and at the rear end of the base 1 along the transmission direction, and the workpiece is positioned by the stops; in this embodiment, the stop spacing on the longitudinal side of the panel 11 is controlled at 170-190mm, and the stop spacing at the rear end of the base 1 along the transmission direction is controlled at 489-1189mm, which meets the effective stop positioning size requirements of most dump truck wall panels.

[0045] The transverse subunit 2 includes a transverse transmission device and a first vertical lifting device installed on the transverse transmission device.

[0046] like Figure 3As shown, the transverse transmission device includes a transverse sub-unit frame 21, and a plurality of longitudinal rollers 22 installed on the transverse sub-unit frame 21 and evenly distributed along the transverse direction. Specifically, it is installed through a bearing seat mounting seat 23, a bearing seat 24 and a bearing seat positioning block 25. The connection method is the existing technology and will not be repeated. The installation method of the longitudinal roller 22 is the same.

[0047] like Figure 4 As shown, the first vertical lifting device includes a vertical cylinder 7 installed below a plurality of longitudinal rollers; guide columns 71 are installed on both sides of the vertical cylinder 7.

[0048] The longitudinal subunit 3 includes a longitudinal transmission device and an oblique lifting device installed on the longitudinal transmission device.

[0049] like Figure 5 As shown, the longitudinal transmission device includes a longitudinal sub-unit frame 31, and four transverse rollers installed on the longitudinal sub-unit frame 31 and arranged in a matrix along the longitudinal and transverse directions; a double-sided sprocket 33, a main transmission shaft 34, a telescopic universal joint 35, a motor, a reducer and an output shaft 37 are installed between the two transverse rollers arranged along the transverse direction; a single-sided sprocket 38 is installed on the ends of the two transverse rollers arranged along the transverse direction, which are away from each other and are located above the double-sided sprocket 33.

[0050] like Figure 6 and Figure 7 As shown, the oblique lifting device is located below the two longitudinally arranged transverse rollers and includes a support base 1 310, a support base 2 311, a movable connector, a lifting cylinder 314, and a connector 315. The support base 1 310 and the support base 2 311 are connected to the longitudinal sub-unit frame 31 via a movable connector. The lifting cylinder 314 is connected between the longitudinal sub-unit frame 31 and the support base 2 311 via a connector 315. Specifically, the end of the lifting cylinder 314 is equipped with a connector 315, which is connected to the connector 315 on the longitudinal sub-unit frame 31 via a pin 313. The tail of the lifting cylinder 314 uses a rear flange and is connected to the support base 2 311 via a pin 313. The support base 1 310 and the support base 2 311 are connected to the base 1. In this embodiment, the movable connector includes a support rod 312 and a pin 313. The lifting cylinder 314 has a stroke of 50 mm, which can meet the required oblique lifting height.

[0051] It also includes an end sub-unit 6; the end sub-unit 6 includes an end transmission device and a second vertical lifting device; the end transmission device includes an end frame and an end roller installed on the end frame; the second vertical lifting device includes a vertical cylinder 7 installed below the end roller and guide columns 71 on both sides of the vertical cylinder 7. The second vertical lifting device has the same structure as the first vertical lifting device, but the installation position is different; in this embodiment, the vertical cylinder is a front flange connection method with a stroke of 50mm, which meets the effective lifting height requirement.

[0052] The clamping device 5 includes a pressure plate 55 mounted on the strip-shaped hole assembly 12 on the panel 11 of the base 1. The clamping device 5 also includes several compression cylinders 51 mounted laterally on the gantry 4. The compression cylinders 51 include a cylinder, a pressure head 52 mounted at the lower end of the cylinder, a cylinder base 53 mounted above the cylinder, and several wheel pairs 54 mounted on the cylinder base 53. The gantry 4 is provided with a positioning bar 41; the positioning bar 41 is located between the wheel pairs 54 and is used to slide and position the compression cylinders 51. The length of the positioning bar 41 is set to match the size of the dump truck wallboard and the clamping position. The pressure plate 55 and the compression cylinders 51 simultaneously achieve the function of clamping the dump truck wallboard.

[0053] When using this welding platform to weld dump truck wall panels, the process is as follows:

[0054] The workpiece is loaded from the end of the base. The second vertical lifting device cylinder of the end subunit rises when the workpiece is loaded, playing an auxiliary role in supporting the workpiece. The roller of the end transmission device cooperates with the longitudinal subunit for transmission.

[0055] Open the longitudinal sub-unit control valve. In the longitudinal direction, the workpiece is lifted and lowered obliquely through the oblique lifting device and the longitudinal transmission device. After the oblique lifting is in place, it is longitudinally transmitted, and the longitudinal positioning of the workpiece is completed from the transportation starting point to the end of the base. Specifically, the cylinder and movable connecting parts equipped with the oblique lifting device lift the workpiece and finally drop it obliquely. At the same time, under the drive of the motor and the reducer, the power is transmitted to the telescopic universal joint through the output shaft, and then transmitted to the main drive shaft through the telescopic universal joint. Then, the double-sided sprockets on the main drive shaft drive the single-sided sprockets on the front and rear rollers through the transmission form of the chain, and finally the rotation of the rollers is realized. The longitudinal positioning of the workpiece is completed by the end of the base, and the longitudinal transmission is completed.

[0056] After the workpiece is transferred to the position in the longitudinal direction, the longitudinal sub-unit control valve is closed and the transverse sub-unit control valve is opened. The cylinder of the first vertical lifting device lifts the workpiece vertically, and the guide column assists in lifting. The workpiece is manually pushed to the stop on the longitudinal side driven by several transverse rollers to complete the transverse positioning of the workpiece. After the stop is in place, the transverse sub-unit control valve is closed, the cylinder descends, and the workpiece falls on the panel. During the transverse and longitudinal conveying process, the workpiece must be lifted and not in contact with the welding platform panel.

[0057] The gantry can move longitudinally along the platform through the track, and the two cylinders on the gantry can move transversely on the beam to achieve flexible compression. When the control valve is opened, the cylinder can be compressed downwards. Figure 8 To ensure that it can adapt to the compression of various products, strip holes are opened on the panel surface to install the pressure plate, such as Figure 1 As shown, this ensures that the product is compacted in all directions.

[0058] The control system of the entire platform includes several control valves, which are installed at the end position of the base with a stop. They can also be adjusted according to actual usage requirements. The longitudinal and lateral lifting can be set in groups. The pneumatic control valves are used to control the operation in groups according to the preset control method; the control valves are also changed to control cabinets, solenoid valves and other forms.

[0059] This embodiment provides a welding platform with longitudinal and transverse conveying and clamping functions, which changes the transmission and positioning method of the existing welding platform. Through the differential settings of longitudinal and transverse transmission and lifting methods, the accuracy of the entire workpiece transmission process is improved, and the welding quality of the workpiece is improved. The longitudinal direction adopts a coordinated lifting method to improve the stability of the longitudinal transmission of the workpiece and improve the positioning accuracy; the transverse direction adopts a vertical lifting method to avoid displacement and at the same time compensate for the positioning error of the longitudinal transmission. The positioning error is first reduced longitudinally, and then the positioning error that may be caused in the longitudinal direction is compensated laterally, which improves the overall transportation efficiency while improving the positioning accuracy. The use of roller transmission reduces the contact surface with the product and reduces the failure points compared to the chain transmission structure; in the transverse transmission, the panel only has holes opened at the corresponding positions of the rollers to reduce the risk of the operator stepping on the air. A pressure plate is added to the clamping device, which has greater compatibility with the workpiece clamping and can better adapt to products of various sizes; the use of multiple control valves can reduce air waste and reduce system energy consumption.

[0060] The above is only an embodiment of the present invention. Common knowledge such as the specific structure and characteristics of the scheme is not described in detail here. Ordinary technicians in the relevant field are aware of all common technical knowledge in the technical field of the invention before the application date or priority date, can obtain all existing technologies in the field, and have the ability to apply conventional experimental means before that date. Ordinary technicians in the relevant field can improve and implement this scheme in combination with their own abilities under the guidance of this application. Some typical well-known structures or well-known methods should not become obstacles for ordinary technicians in the relevant field to implement this application. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
