Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of truck floor welding equipment, and in particular to automatic loading and unloading rapid assembly welding equipment for truck floors. Background Art

[0002] The truck floor is composed of a rectangular main board and multiple C-shaped beams. During the production process, the C-shaped beams are evenly buckled on the main board along the longitudinal direction of the main board, and the two end faces of the C-shaped beams with openings are parallel to the transverse direction of the main board. After the main board and the beams are welded, the floor needs to be turned over before the truck compartment is assembled so that the C-shaped beams are located below the main board.

[0003] In the prior art, the truck floor welding device adopts resistance welding, two-protection welding, argon arc welding and other methods. Before welding, the operator first places the main board on the assembly station using a lifting crane, and then places the crossbeam, and finally starts the clamping device to clamp the crossbeam so that the crossbeam is completely in line with the surface of the main board. However, during use, the lifting of the main board by the lifting crane is not only inefficient, but also poses a safety hazard. The crossbeams are placed on the main board by personnel. Although the spacing between the crossbeams can be determined according to the position of the clamping device, there is no horizontal positioning function on the main board, and it depends entirely on the judgment of the personnel. It is not only prone to misoperation, but also not conducive to the stability of the truck floor during use. Summary of the invention

The swing pushers are configured to be able to approach the main board and abut against the side edges of the main board to position the main board under the drive of the sliding members, and to swing vertically to avoid the main board under the continued drive of the sliding members.

[0006] For example, in the automatic loading and unloading, rapid assembly and welding equipment for the truck floor provided by at least one embodiment of the present invention, the horizontal projection of the positioning block is conical, and the size of the positioning block gradually decreases from the end close to the sliding member to the end far from the sliding member.

[0009] For example, in the automatic loading and unloading, rapid assembly and welding equipment for the truck floor provided by at least one embodiment of the present invention, it further includes a swinging pressing member for pressing down the cross beam, and the swinging pressing member includes: A lifting member, which is arranged on the sliding member in a lifting manner; A main body, one end of which is rotationally connected to the lifting member, and a pressing plate is arranged at the other end, and the main body can swing vertically so that the pressing plate abuts against the top of the cross beam; A first connecting rod, which has a first end and a second end, the first end is rotationally arranged on the sliding member, the second end is rotationally arranged on the main body, and the lifting member can move upward and drive the main body and the first connecting rod to swing so that the pressing plate abuts against the top of the cross beam.

[0010] For example, in the automatic loading and unloading, rapid assembly and welding equipment for the truck floor provided by at least one embodiment of the present invention, the pressing plate is slidably arranged on the main body, and the swinging pressing member further includes: A second elastic member, two ends of which respectively act on the main body and the pressing plate, and the second elastic member is used to elastically push down the pressing plate downward so that the pressing plate abuts against the top of the cross beam.

An angle with a downward opening is formed between the second connecting rod and the third connecting rod. The sliding member can slide toward the side close to the main board to jack up the lifting member upward by means of the second connecting rod and the third connecting rod; A third elastic member, the two ends of which act on the second connecting rod and the third connecting rod respectively. The third elastic member is used to provide a force for the second connecting rod and the third connecting rod to rotate and push the positioning block and the sliding member away from each other.

[0024] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0025] As Figures 1 to 7 shown, it shows an automatic loading and unloading and rapid assembly welding device for the truck floor in an embodiment of the present invention, including a moving device 100, a sliding member 200, a positioning block 300, and a swinging pusher 410. The moving device 100 adopts an orbital conveying structure and is composed of two parallel guide rails and at least one slide that can slide along the guide rails. The main function of the moving device 100 is to convey the floor to be welded to the welding station. In the actual production process, it can accurately convey the sliding member 200 with the main board and cross beam placed thereon under the welding equipment according to a preset program. After welding, it conveys the welded floor out of the welding station, realizing automatic material conveying, improving production efficiency, and at the same time avoiding the safety hazards brought by manual hoisting.

[0026] There are two sliding members 200, both of which are slidably arranged on the moving device 100. A slider is installed at the bottom of the sliding member 200, and the slider cooperates with the chute on the surface of the slide of the moving device 100 to ensure that the sliding member 200 can slide smoothly on the slide without excessive shaking. The two sliding members 200 can slide simultaneously on the slide of the moving device 100, approaching or moving away from each other, so as to adjust the size of the placement space 210 formed between them. This placement space 210 is used to place the main board and cross beam. During the assembly process, the movement of the sliding member 200 can make the positioning block 300 and the swinging pusher 410 approach or move away from the main board and cross beam, realizing the positioning and centering operations on them.

[0027] There are two groups of positioning blocks 300. The two groups of positioning blocks 300 are respectively arranged on the two sliding members 200. Each group of positioning blocks 300 has several positioning blocks 300 arranged longitudinally along the main board, and the number of each group of positioning blocks 300 is the same as the number of cross beams. The shape of the positioning block 300 is trapezoidal, and the hypotenuse of the trapezoid faces the cross beam. Such a design can play a better guiding role when pushing the cross beam.

[0028] There are two swing pushers 410, which are respectively arranged on two sliding members 200, and the rotation axis is parallel to the longitudinal direction of the main board, so as to ensure that the swing pushers 410 can rotate smoothly. After the two swing pushers 410 are close to each other through the sliding member 200, their arc-shaped surfaces abut against the two ends of the main board, pushing the main board to be centered in the placement space 210.

[0029] Working principle: First, place the mainboard in the placement space 210 between the two sliding members 200, and place the crossbeam on the mainboard. The placement position of the crossbeam and the position of the mainboard should minimize the deviation. Start the device, the slide table drives the two sliding members 200 to move to the appropriate position, and then control the two sliding members 200 to slide towards the mainboard at the same time. During the sliding process, the two swing pushers 410 gradually approach the two ends of the mainboard, and the positioning block 300 also approaches the placement space 210. When one surface of the swing pusher 410 contacts the two ends of the mainboard, the sliding member 200 continues to be pushed, and the swing pusher 410 pushes the mainboard to the center of the placement space 210, so as to realize the centering of the mainboard in the placement space 210.

[0030] At this time, the placement position of the beam is relatively accurate, but it still needs to be positioned horizontally. After the push block is rotated to avoid, the sliding member 200 continues to drive the positioning block 300 to slide close to the beam in the placement space 210, so that the positioning block 300 abuts against the beam. After one edge of the positioning block 300 contacts the two ends of the beam, as the sliding member 200 continues to slide, the positioning block 300 gradually pushes the beam so that the beam is centered in the lateral direction of the main board. When the main board and the beam are both centered, the mobile device 100 transports the sliding member 200 with the main board and the beam to the welding station. The welding equipment can use automated resistance welding, two-protection welding or other suitable welding methods to weld the main board and the beam. During the welding process, the mobile device 100 remains stationary to ensure the stability of the welding process. After welding is completed, the mobile device 100 transports the welded truck floor out of the welding station.

[0031] When the sliding member 200 drives the positioning block 300 to approach the beam in the placement space 210, the bevel of the positioning block 300 contacts the two ends of the beam. As the sliding member 200 continues to slide, the positioning block 300 gradually pushes the beam, so that the beam is centered in the placement space 210, solving the problem of the difficulty in lateral positioning of the beam on the mainboard. The swing pusher 410 realizes the precise centering of the mainboard in the placement space 210, and will not interfere with the positioning of the beam by the positioning block 300 in subsequent operations, thereby improving the automation and production efficiency of the entire assembly process.

[0032] The positioning functions of the positioning block 300 and the swing pusher 410 reduce the time for manual positioning, making the assembly and welding process of the truck floor more efficient. The positioning block 300 and the swing pusher 410 can position the main board and the cross beam, solve the problem of difficult lateral positioning of the cross beam on the main board, ensure the uniformity of the distances between both ends of the cross beam and both ends of the main board, and improve the structural stability and quality of the truck floor. In actual use, the flatness and strength of the truck floor are improved, reducing truck failures and maintenance costs caused by floor quality problems.

[0033] In some examples, the positioning block 300 is a conical plate-like structure, and the tips of the two groups of positioning blocks 300 both face the placement space 210. Driven by the sliding member 200, the positioning block 300 approaches the cross beam, and its conical outer wall abuts against the inner walls at both ends of the cross beam, which can not only achieve the lateral positioning of the cross beam on the main board, but also longitudinally position the cross beam along the main board, ensuring the accuracy of the position of the cross beam on the main board and improving the overall structural stability of the truck floor.

[0034] In some examples, a first elastic member 420 is further included. Both ends of the first elastic member 420 act on the sliding member 200 and the swing pusher 410 respectively. After the two swing pushers 410 abut against both sides of the main board respectively, when the sliding members 200 continue to slide closer to each other, the mutual acting force generated by the two swing pushers 410 acts on the swing pusher 410 through the main board, causing the swing pusher 410 to compress the first elastic member 420 and forcing the swing pusher 410 to rotate and avoid the main board, thus preventing the sliding members 200 from continuing to slide closer and causing damage to the main board. After welding is completed, the two sliding members 200 drive the two swing pushers 410 to move away from each other. After the swing pusher 410 leaves the main board, the elastic force of the first elastic member 420 causes the swing pusher 410 to reset to a position where it can push the main board, facilitating the next use.

[0035] In some examples, the moving device 100 includes a support frame 110, rollers 120, and a positioning plate 130. The support frame 110 is slidably arranged relative to the ground, and the support frame 110 can slide closer to or away from the welding device. A plurality of rollers 120 are rotatably arranged on the support frame 110. The rollers 120 can be driven by a motor to actively convey the main board in the placement space 210, so that the front end of the main board along the conveying direction of the rollers 120 abuts against the positioning plate 130, thereby completing the longitudinal positioning of the main board. The rollers 120 can also rotate passively, enabling the operator to adjust the position of the main board by pushing after placing the main board in the placement space 210, so that one end of the main board abuts against the positioning plate 130, thereby completing the longitudinal positioning of the main board.

[0036] In some examples, it further includes: The swing pressing member 500 is rotatably arranged on the sliding member 200. The rotation axis of the swing pressing member 500 is longitudinally parallel to the main board in the placement space 210. The swing pressing member 500 can rotate to approach the cross beam in the placement space 210 so as to press the cross beam. The swing pressing member 500 includes a lifting member 510, a main body 520, a first connecting rod 530 and a pressing plate 540.

[0037] The lifting member 510 is in a rectangular block structure and can move up and down relative to the sliding member 200. One end of the main body 520 is rotatably arranged on the lifting member 510. Both ends of the first connecting rod 530 are rotatably connected to the sliding member 200 and the main body 520 respectively through pin shafts. The length and angle of the first connecting rod 530 are determined according to the positional relationship between the main body 520 and the sliding member 200 to ensure that the main body 520 can accurately rotate close to or away from the cross beam. The pressing plate 540 is arranged at one end of the main body 520 away from the lifting member 510. After the lifting member 510 moves to drive the main body 520 to rotate close to the placement space 210, the pressing plate 540 directly contacts the cross beam to press the cross beam. The pressing of the cross beam by the pressing plate 540 can make the bottom of the cross beam completely abut against the top of the main board, improving the welding quality. The surface of the pressing plate 540 in contact with the cross beam is set to be arc-shaped to adapt to the way that the pressing plate 540 rotates close to the cross beam through the main board and avoid scratching the surface of the cross beam.

[0038] Wherein, one end of the first connecting rod 530 rotatably connected to the sliding member 200 is realized through a base vertically supported by the sliding member 200, and the lateral positioning of the base is realized through the pin shaft hinge axis between the first connecting rod 530 and the base.

[0039] In some examples, the pressing plate 540 can slide relative to the main body 520. A second elastic member 550 is arranged between the pressing plate 540 and the main body 520. The second elastic member 550 adopts a helical spring. Through the sliding of the second elastic member 550 and the pressing plate 540, the pressing plate 540 can adapt to cross beams of different heights without changing the rotation axis of the main board.

[0040] In some examples, the positioning block 300 and the slider 200 are connected by a connecting member 600. The connecting member 600 includes a second connecting rod 610, a third connecting rod 620, and a third elastic member 630. One end of the second connecting rod 610 is hinged to the positioning block 300; one end of the third connecting rod 620 is hinged to the slider 200, and the rotation axes of both the second connecting rod 610 and the third connecting rod 620 are parallel to the longitudinal direction of the main board. The second connecting rod 610 and the third connecting rod 620 are also hinged together by a pin shaft. Both the second connecting rod 610 and the third connecting rod 620 are located between the slider 200 and the positioning block 300. The third elastic member 630 acts on the hinge joint of the second connecting rod 610 and the third connecting rod 620. The third elastic member 630 is a torsion spring, and to make the second connecting rod 610 and the third connecting rod 620 rotate relative to each other, the deformation force of the third elastic member 630 needs to be overcome first.

[0041] Working principle: When the device does not need to perform positioning, the included angle between the second connecting rod 610 and the third connecting rod 620 is not equal to 180 degrees. After the main board and the cross beam are both placed in the placement space 210, the device is started to make the two sliders 200 approach each other. Since there is a third elastic member 630 between the second connecting rod 610 and the third connecting rod 620, the deformation force of the third elastic member 630 will provide resistance for the relative rotation of the second connecting rod 610 and the third connecting rod 620. Therefore, the slider 200 can first push the positioning block 300 close to the cross beam through the third connecting rod 620 and the second connecting rod 610. After one end of the positioning block 300 abuts against one end of the cross beam, when the slider 200 continues to slide, it will bear the reaction force brought by the cross beam, thereby compressing the third elastic member 630 and enabling the second connecting rod 610 and the third connecting rod 620 to rotate relative to each other.

[0042] The third elastic member 630 can prevent the slider 200 from sliding excessively and causing the cross beam to be squeezed and damaged.

[0043] In some examples, it further includes a pushing member 640. The pushing member 640 is a rectangular block or a round rod. The two ends of the pushing member 640 are respectively arranged at the hinge joint of the second connecting rod 610 and the third connecting rod 620 and the lifting member 510. As the slider 200 moves, when the second connecting rod 610 and the third connecting rod 620 squeeze the third elastic member 630 and rotate relative to each other, the height of the hinge joint of the second connecting rod 610 and the third connecting rod 620 rises or falls. At this time, the change in the height of the hinge joint of the second connecting rod 610 and the third connecting rod 620 acts on the lifting member 510 through the pushing member 640 to provide lifting power for the lifting member 510. Then the lifting member 510 lifts or lowers to make the pressing plate 540 press or loosen the cross beam.

[0044] Through the pushing member 640, not only is the driving device of the lifting member 510 saved, but also during the assembly process of the cross beam and the main board, the cross beam is first positioned in a pressing manner. And during the blanking process after the bottom plate is welded, the two sliding members 200 slide away from each other. Due to the elastic deformation force of the third elastic member 630, the second connecting rod 610 and the third connecting rod 620 first rotate relative to each other, causing the lifting member 510 to drive the pressing plate 540 away from the cross beam, and then causing the positioning block 300 to move away from the cross beam.

[0045] In some examples, the sliding member 200 includes a sliding strip plate 240, a first connecting seat 220, and a driven plate group 230.

[0046] The sliding strip plate 240 is slidably arranged on the support frame 110, and sliders are installed at the bottom, which cooperate with the guide rails on the support frame 110 to achieve smooth sliding. An installation seat for the swing pusher 410 is provided on the sliding strip plate 240, and the swing pusher 410 is fixed by bolts to ensure the rotational stability of the swing pusher 410.

[0047] The first connecting seat 220 is a rectangular block structure and is detachably arranged on the sliding strip plate 240 by bolts. The third connecting rod 620 is hinged to the first connecting seat 220 to ensure firm connection. The detachable manner of the first connecting seat 220 not only facilitates maintenance and replacement, but also enables the operator to change the position of the positioning block 300 by disassembly, so as to be applicable to the positioning of cross beams with different spacings.

[0048] The driven plate group 230 is connected to the moving device 100 through linear guide rails, and the sliding direction is parallel to that of the sliding strip plate 240. An installation hole for the positioning block 300 is provided on the driven plate group 230, and the driven plate group 230 provides a supporting function for the positioning block 300, enabling the positioning block 300 to always be at the same height.

[0049] The swing pusher 410 is rotatably arranged on the sliding strip plate 240 through the installation seat, and the installation seat penetrates through the driven plate group 230 and is fixedly connected to the sliding strip plate 240.

[0050] In some examples, a screw rod 700 is further included. The screw rod 700 is rotatably arranged on the moving device 100 and is supported by bearing seats at both ends. The two ends of the screw rod 700 have thread segments with opposite thread directions, which cooperate with the threaded holes of the two sliding members 200. When the screw rod 700 rotates, due to the opposite thread directions at both ends, the two sliding members 200 will move closer to or away from each other simultaneously, facilitating the adjustment of the size of the placement space 210 to meet the assembly requirements of main boards and cross beams with different sizes.

[0051] Working principle: Place the main board and the cross beam in the placement space 210 between the two sliding members 200, with the cross beam placed on the main board. The roller 120 of the moving device 100 rotates driven by the motor, driving the main board to move. When one end of the main board abuts against the positioning plate 130, the longitudinal positioning of the main board is completed. At this time, rotate the control screw 700 to make the two sliding members 200 approach each other. The swing pusher 410 first abuts against the two transverse ends of the main board, pushing the main board for transverse positioning. After both swing pushers 410 abut against the main board, the swing pusher 410 presses the first elastic member 420, causing the swing pusher 410 to rotate and avoid the main board. At this time, the two sliding members 200 continue to approach and slide relative to each other under the action of the screw 700, thereby continuing to drive the positioning block 300 closer to the cross beam. After the positioning block 300 abuts against the two ends of the cross beam for positioning, the third elastic member 630 is compressed through the second connecting rod 610 and the third connecting rod 620, changing the height of the hinge point between the second connecting rod 610 and the second connecting rod 610. The top pusher 640 is activated, driving the lifting member 510 to rise. The main body 520 rotates through the first connecting rod 530, and the pressing plate 540 approaches the cross beam. At the same time, the second elastic member 550 makes the pressing plate 540 tightly press against the cross beam, preparing for welding.
