Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of frame welding, in particular to a welding device for bed plate frame. BACKGROUND

[0002] In the production process of the nursing bed frame, the support structure at the bottom of the bed plate is formed by welding a frame composed of multiple hollow profiles. The core process is the positioning and clamping of multiple square tube workpieces and continuous welding. Currently, during welding, two profiles are generally fixed, and the welding of the corner of one of them is performed. After welding, the profile needs to be turned over to perform double-sided welding. Therefore, the position of the profile needs to be changed multiple times during the welding process, which is complicated and inconvenient to operate.

[0003] To solve the above problems, Chinese patent 202211128614.9 discloses an aluminum window frame welding positioning tool, which includes a center frame. Four extension mechanisms are provided on the side ends of the center frame. A moving shell is provided on the extension mechanism. A rotating threaded rod is rotatably provided inside the moving shell. Two extension holes are provided on the side end of the moving shell away from the center frame. A horizontal clamping plate is slidably provided in the extension hole. A traction mechanism is provided inside the moving shell for pulling the horizontal clamping plate at a higher position. A cooperating block is provided on one end of the horizontal clamping plate away from the moving shell. Two cooperating blocks are oppositely arranged. A rotating support seat is provided on the cooperating blocks. The existing technology can directly fix the four profiles of the aluminum window frame without the need to repeatedly fix the profiles. The positioning efficiency is higher, and the operation is more convenient, which improves the work efficiency. The tool can clamp profiles of different thicknesses, widths and lengths, and has a wide range of applications.

[0004] Although the above technology does not need to repeatedly fix the profiles during welding, it still relies on manual placement and positioning of the profiles during initial loading. The efficiency is low when producing nursing bed plate frames in batches, and manual operation can easily cause positioning deviation of the profiles. Therefore, we propose a welding device for bed plate frame. SUMMARY

[0005] To solve the above technical problems, the present application provides a welding device for bed plate frame, which includes a longitudinal beam stock bin and a cross beam stock bin. The longitudinal beam stock bin and the cross beam stock bin are both provided with multiple support frames. A self-positioning clamping unit is slidably arranged on the support frame. The self-positioning clamping unit includes a mounting frame, a longitudinal beam clamping unit, a cross beam clamping unit and a longitudinal beam centering unit. Welding mechanical arms are provided on both sides of the self-positioning clamping unit.

[0006] In some embodiments, the longitudinal beam stock bin and the cross beam stock bin each include a box body and a jacking cylinder provided at the bottom of the box body. A plurality of square steel profiles are stacked above the top plate provided at the output end of the jacking cylinder.

[0007] In some embodiments, the longitudinal beam hopper has a longitudinal opening slot on one side of its body that abuts against the transverse beam hopper, the transverse beam hopper has transverse opening slots on both sides of its body, an avoidance slot is also provided on the outer side of its body, and centering slots are provided at both ends of the longitudinal beam hopper's body.

[0008] In some embodiments, the mounting frame includes longitudinal bars and transverse bars, which are connected to each other to form a "well" shape. Each end of the transverse bar is provided with a connecting plate, and a lifting block is fixedly provided on the connecting plate. A lifting screw is rotatably provided on a support frame near the transverse bar. A motor is provided on the support frame, and the output end of the motor is connected to the lifting screw for transmission. The lifting screw is threaded through the lifting block.

[0009] In some embodiments, the longitudinal beam clamping unit is provided in two sets and is respectively provided at the left and right ends of the crossbar. The longitudinal beam clamping unit includes a movable frame, which is in the shape of an "I". The movable frame is slidably disposed at the end of the crossbar, and two sets of opposing longitudinal beam clamping cylinders are provided at both ends of the movable frame.

[0010] In some embodiments, slide rails are embedded at both ends of the crossbar, a slider is slidably disposed in the slide rails, the movable frame is fixedly disposed at the bottom of the slider, a propulsion cylinder is fixedly disposed on the connecting plate, and the output end of the propulsion cylinder is fixedly connected to the movable frame.

[0011] In some embodiments, the beam clamping unit includes a mounting beam arranged along the longitudinal direction, a plurality of beam clamping cylinders are provided at the bottom of the mounting beam, the beam clamping cylinders are arranged in pairs facing each other, and the mounting beam is fixedly installed at the bottom of the crossbar.

[0012] In some embodiments, the longitudinal beam centering unit includes extension plates fixedly disposed on both sides of the mounting beam, and a centering cylinder is fixedly installed at the bottom of the extension plate, the output direction of the centering cylinder being consistent with the length direction of the longitudinal beam.

[0016] 1. By setting up longitudinal beam hoppers and transverse beam hoppers, automatic feeding and pre-assembly of various profiles can be completed. During the welding process, the frame only needs to be positioned once. The self-positioning clamping unit can move up and down to pick up the material. Furthermore, its ability to move up and down facilitates welding at the bottom of the frame.

[0017] 2. The "re-clamping centering system" formed by the longitudinal beam clamping unit and the longitudinal beam enables the longitudinal beams to be centered in the length direction of the cross beam by moving closer to each other when splicing the cross beam. BRIEF DESCRIPTION OF DRAWINGS

[0037] The beam clamping unit 6 can clamp the beam vertically along its length direction, and since the beam is located between the longitudinal beams, after the longitudinal beams are clamped, the length direction of the beam can be directly centered and positioned through the longitudinal beams, and then tightly clamped through the beam clamping unit 6, and then the welded mechanical arm 8 can weld the spliced section bar, and since the self-positioning clamping unit is slidably arranged on the support frame 3, the spliced frame can slide up and down along the support frame 3, and during the welding of the upper layer of the frame, the self-positioning clamping unit can make the frame at a lower position, at which time the welding mechanical arm 8 can weld the upper layer of the frame, and then the self-positioning clamping unit drives the frame to move upwards, so that the welding mechanical arm 8 can weld the lower layer of the frame, and during the welding process, the frame only needs to be positioned once, and since the hopper is provided, the self-positioning clamping unit itself needs to move up and down to take the material, and thus through the up-and-down movable arrangement, the welding of the bottom of the frame can also be facilitated.

[0039] The box body 21 of the longitudinal beam hopper 1 is provided with a longitudinal opening slot 9 on one side of the box body 21 of the beam hopper 2, so that the uppermost longitudinal beam can move in the direction close to the beam after being pushed out, thereby splicing the longitudinal beam and the beam, the box body 21 of the beam hopper 2 is provided with a transverse opening slot 10 on both sides of the box body 21, and the transverse opening slot 10 also provides space for the movement of the longitudinal beam, and the box body 21 is further provided with an avoiding slot 11, which can allow the longitudinal beam clamping unit 5 and the beam clamping unit 6 to pass through, thereby ensuring the clamping of the longitudinal beam clamping unit 5 and the beam clamping unit 6 to the longitudinal beam and the beam without affecting the limiting of the longitudinal beam and the beam at the top end of the box body 21, and the box body 21 of the longitudinal beam hopper 1 is provided with a centering slot 12 at both ends, which can provide space for the longitudinal beam centering unit 7 to expose both ends of the longitudinal beam square steel, thereby allowing the longitudinal beam to be centered and positioned by the longitudinal beam centering unit 7.

[0040] In order to facilitate the loading and replenishment of the longitudinal beam hopper 1 and the beam hopper 2, reference is made to Figure 7 and Figure 8One side of the housing 21 is designed to be movable. The movable plate is equipped with a rod that can be inserted into the main body of the housing 21. With this design, when adding profiles, the plate can be pulled open to easily add profiles.

Both ends of the transverse rod 42 are provided with connecting plates 43, and lifting blocks 13 are fixedly installed on the connecting plates 43. A lifting screw 14 is rotatably installed on the support frame 3 near the transverse rod 42. A motor is installed on the support frame 3, and the output end of the motor is connected to the lifting screw 14 for transmission. The lifting screw 14 is threaded through the lifting block 13, thereby driving the motor to... When the lifting screw 14 rotates, it can drive the mounting frame 4 to move through the lifting block 13, thereby driving the longitudinal clamping unit, the crossbeam clamping unit 6 and the longitudinal beam centering unit 7 on the mounting frame 4 to move up and down. In actual use, the motor is set as a self-locking motor, which can lock the mounting frame 4 at any height.
