Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are for purposes of illustration only and are not to be construed as limitations of the invention. It should be noted that, for convenience of description, only the parts related to the present invention are shown in the drawings.

In the present invention, the embodiments and the features of the embodiments may be combined with each other without conflict. The present invention will be described in detail with reference to the accompanying drawings in conjunction with embodiments.

As shown in fig. 1, 2 and 3, the utility model provides an underframe welding table, which comprises a mounting frame 1, a frame 2 and a plurality of driving rollers 3 rotatably supported on the frame 2; the rack 2 is also provided with a plurality of vertical top plates 4 capable of moving up and down, the length direction of the top plates 4 is consistent with the width direction of the rack 2, and the top plates 4 are respectively positioned between two adjacent driving rollers 3; a first pushing device 5 for pushing the top plate 4 is further arranged below the rack 2; a second pushing device 6 which pushes downwards is fixedly arranged on the mounting frame 1, and a pressing frame 7 is fixedly arranged at the lower end of the second pushing device 6.

The axial direction of the driving roller 3 is consistent with the width direction of the frame 2, and the driving roller 3 is supported on the frame 2 through a bearing seat. The thickness direction of the top plate 4 is consistent with the length direction of the rack 2, the length of the top plate 4 is smaller than the width of the rack 2, the top plate 4 is positioned in the middle of the two adjacent driving rollers 3, the distance between the two adjacent top plates 4 is equal to the distance between the two adjacent driving rollers 3, and therefore supporting force borne by the rack in the transmission process and supporting force borne by the rack in the jacking process are uniformly distributed below the rack, and the supporting force borne by the rack is balanced all the time. By arranging the first pushing device 5 below the frame 2, the top plate 4 can quickly jack up the frame when the top plate 4 is subjected to upward pushing force exerted by the first pushing device 5. Compress tightly frame 7 and be located frame 2 directly over, compress tightly frame 7 and be "king" style of calligraphy, compress tightly frame 7 and can not only compress tightly frame 2 by the jack-up, can compress tightly on the frame with frame welded plate with needs simultaneously, make things convenient for the welding of frame and plate more accurate convenience.

The driving rollers 3 are uniformly distributed along the length direction of the frame 2 at intervals, so that the frame can be conveyed more conveniently and smoothly in the feeding and discharging processes, and the supporting force of the frame in the conveying process is more balanced. Roof 4 between two adjacent driving rollers 3 is two, and two roofs 4 are bilateral symmetry and arrange, has the clearance between two roofs 4, makes the frame make by jack-up, and the left and right sides of frame can support through two roofs 4 respectively, makes the welding of frame more convenient.

The lower surfaces of the two top plates 4 are fixedly provided with connecting rods 8, and the connecting rods 8 penetrate through the rack 2 and vertically downwards; the lower extreme of two connecting rods 8 all articulates and is provided with tripod 9, and two tripods 9 all include first angle 9a, second angle 9b and third angle 9c, and the lower extreme of connecting rod 8 is articulated with the first angle 9a of tripod 9, and the second angle 9b of two tripods 9 all articulates on frame 2, and the both ends of first thrust unit 5 are articulated with the third angle 9c of two tripods 9 respectively. Connecting rod 8 is cylindric, offers the through-hole that supplies connecting rod 8 to remove about from top to bottom on the frame 2, makes things convenient for connecting rod 8 to run through frame 2 and reciprocates, and reciprocating of connecting rod 8 to make roof 4 realize reciprocating. The tripod 9 is a fixed tripod 9, and the third angle 9c of the tripod 9 moves towards the left and right sides of the frame 2 respectively by the pushing of the first pushing device 5, the first angle 9a of the tripod 9 moves upwards relatively, and at the moment, the connecting rod 8 moves upwards relatively, so that the top plate 4 is jacked up.

The left and right sides of roof 4 all is provided with baffle 10, baffle 10 is fixed in frame 2, the length direction of baffle 10 is unanimous with the length direction of roof 4, the length of baffle 10 is less than the length of roof 4, make the both ends of roof 4 extend to the both ends of baffle 10 respectively, clearance between two baffles 10 matches with the thickness of roof 4, through setting up two baffles 10, make the mounting groove that forms both ends and run through between two baffles 10, thereby make roof 4 when not by the state of jack-up, roof 4 contracts to in the mounting groove, make roof 4 receive the protection, prevent that roof 4 from taking place the slope. The upper surface of roof 4 is provided with protruding dogtooth 11 that makes progress, and when making the frame by roof 4 jack-up, the frame can be firm stops on roof 4, prevents that the frame from rocking or sliding on roof 4.

The upper end of the guide rod 12 penetrates through the guide hole 13 and vertically extends upwards, and the upper end of the guide rod 12 is fixedly provided with a limiting rod 14. The number of the guide rods 12 is at least two, and the guide rods 12 are symmetrically arranged at the front end and the rear end of the pressing frame 7; the limiting rod 14 is perpendicular to the guide rod 12, so that when the pressing frame 7 is pushed downwards by the second pushing device 6, the pressing frame 7 always moves up and down on the same vertical straight line; meanwhile, when the pressing frame 7 is separated from the second pushing device 6, the guide rod 12 enables the pressing frame 7 to be continuously connected to the lower end of the mounting frame 1, the pressing frame 7 separated from the second pushing device 6 is prevented from directly falling, and the mounting performance of the pressing frame 7 is improved.

The number of the second pushing devices 6 is two, and the two second pushing devices 6 are respectively located at two ends of the pressing frame 7, so that in the process that the pressing frame 7 is pushed downwards by the second pushing devices 6, the pressing frame 7 is more balanced in the downward pushing force, and the pressing frame 7 is prevented from shaking in the downward moving process. The first pushing device 5 and the second pushing device 6 are both telescopic cylinders.

When the frame need weld, roof 4 contracts to between two baffles 10, the highest height of baffle 10 this moment is less than the highest height of driving roller 3, the frame is earlier through driving roller 3 on frame 2 with frame 2 complete movement to driving roller 3 this moment, when the frame is located on driving roller 3 completely, roof 4 rebound when first thrust unit 5 promoted, make roof 4 with the frame complete jack-up on driving roller 3, the frame top will be placed with frame welded plate this moment, then second thrust unit 6 promotes to compress tightly frame 7 and moves downwards, compress tightly frame 7 with the plate on the frame, make frame and plate closely cooperate, welding set begins to weld this moment, welding set welds the plate on the frame. When the welding of the frame is finished, the second pushing device 6 begins to contract, so that the pressing frame 7 begins to move upwards, the first pushing device 5 begins to contract, the top plate 4 begins to move downwards, when the top plate 4 completely contracts between the two baffle plates 10, the welded frame automatically drops on the driving roller 3, and at the moment, the driving roller 3 rotates to send out the welded frame.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
