Description

Technical Field

[0001] The utility model belongs to the field of welding cabinet structure design, in particular to a moving device for a welding cabinet. Background Art

[0002] In the field of stainless steel gas box product processing, because of the requirement for overall sealing, most products are integrally welded structures; generally, spot welding is first performed on welded products to give the product a basic shape, and then full welding is performed on the product to ensure the tightness of the welding points of the welded products. Existing cabinet products are developing towards multi-joint structures, resulting in large product weight and size. During the welding process, the labor intensity of manually flipping and translating the product is very high, which will also lead to low efficiency of the welded products. In addition, because most of the existing industrial welding is performed by robotic arms, the accuracy of welding by human movement and robotic arms is difficult to control. For large-scale industrial production, the cost of manual movement is also relatively high.

[0003] In summary, the existing method of manually moving welding products during welding processing has the problems of low efficiency and poor precision. Utility Model Content

[0004] The utility model aims to provide a moving device for a welding cabinet, so as to solve the technical problem that the method of manually moving welding products in the welding process of the prior art has the problems of low efficiency and poor precision.

[0007] The beneficial effect is that the support frame sequentially supports the translation mechanism, the lifting and rotating mechanism and the flipping mechanism, the cabinet to be welded first reaches the flipping mechanism through the translation mechanism, the flipping mechanism lowers the height of the cabinet to be welded by flipping, so that the robot arm or manual welding of the unobstructed parts is convenient, and after welding, the cabinet to be welded is flipped to the original position and moved to the lifting and rotating mechanism through the translation mechanism, the lifting and rotating mechanism first pushes up, then rotates, and then pulls down the cabinet to be welded, and the cabinet to be welded is sent to the flipping mechanism again through the translation mechanism, and the cabinet to be welded is flipped through the flipping mechanism, so that the robot arm or manual welding can be carried out to the part that was blocked last time, thereby realizing the welding of all welding parts of the cabinet to be welded, and compared with the prior art, the mobile device is more labor-saving and more precise.

[0008] As a further improvement, the flipping mechanism includes a fixed part and a movable supporting plate hinged on the fixed part; the end of the movable supporting plate away from the translation mechanism is vertically fixedly connected to the flipping tray; the flipping mechanism also includes a telescopic mechanism, one end of which is connected to the support frame, and the other end is connected to the position of the movable supporting plate deviating from the hinge point.

[0009] The beneficial effect is that the cabinet to be welded drives the mobile support plate to flip around the hinge point through the telescopic mechanism, and then drives the flip tray connected to the mobile support plate to flip, and the flipping of the cabinet to be welded can be achieved by cooperating with the mobile support plate and the flip tray.

[0010] As a further improvement, the telescopic mechanism includes a screw driven by a screw motor, a screw nut cooperating with the screw, a slider slidably connected to a slide rail on a support frame and fixedly connected to the screw nut, and a support connecting rod with one end hinged to the slider; the other end of the support connecting rod is hinged to the bottom surface of the movable support plate.

[0011] The beneficial effects are: the screw motor drives the screw to make the screw nut connected to it move horizontally, and the screw nut drives the supporting connecting rod, further driving the mobile supporting plate to flip; the screw nut is also slidably connected to the slide rail on the support frame, providing supporting force when the screw drives the mobile supporting plate to flip, thereby reducing wear on the screw.

[0012] As a further improvement, the sliders include two, the two sliders are respectively fixedly connected to the two sides of the lead screw nut and are slidably connected to the two slide rails of the support frame, and the corresponding support connecting rods also include two.

[0013] The beneficial effect is that the support plate is moved by supporting the two sliding blocks to ensure the stability of the support.

[0014] As a further improvement, the screw is a ball screw.

[0017] The beneficial effect is that the roller drives the cabinet to be welded to move horizontally more conveniently and labor-savingly.

[0018] As a further improvement, the lifting and rotating mechanism includes a rotating tray for driving the cabinet to be welded to rise, fall and rotate, and also includes a piston cylinder for pushing up and pulling down.

[0019] The beneficial effect is that the piston cylinder provides the lifting and rotating mechanism with lifting and rotating power, so that the lifting is smoother and the influence of the lifting and rotating on the cabinet to be welded is further reduced.

[0020] As a further improvement, a fixed plate is fixedly arranged on the upper surface of the piston cylinder body for driving the rotating tray to rise and fall, and a guide rod slidingly arranged on the plate body of the fixed plate is connected to the rotating tray to ensure the verticality of the lifting.

[0021] The beneficial effect is that the rising and falling trajectories of the fixed plate are limited by the guide rod to ensure the verticality of the lifting, while also improving the efficiency of the power generated by the piston cylinder and reducing the waste of power.

[0022] As a further improvement, a bracket for supporting the cabinet to be welded is also provided on the rotating tray.

[0023] The beneficial effect is: since the cabinet to be welded is relatively large, it is impossible to translate the center exactly to the center of the pallet during translation. In order to avoid the cabinet to be welded having an unstable center of gravity, unbalanced and tilted on the pallet, a bracket is designed to support the cabinet to be welded.

[0024] As a further improvement, the bracket is a rotationally symmetrical single-rod bracket.

[0025] The beneficial effect is: while ensuring the supporting effect, the amount of material used for the bracket is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model, that is, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0043] Embodiment of the moving device of welding cabinet:

[0044] like Figure 1-3 As shown, the moving device of the welding cabinet includes a translation mechanism 1 for translating the cabinet to be welded, a lifting and rotating mechanism 2 for lifting and rotating the cabinet to be welded, and a flipping mechanism 3 for flipping the cabinet to be welded and a support frame. The translation mechanism 1 is arranged on both sides of the support frame, the lifting and rotating mechanism 2 is arranged between the translation mechanisms 1, and the flipping mechanism 3 is arranged at the other end of the support frame 4. The upper surface of the lifting and rotating mechanism 2 is flush with or lower than the translation surface of the translation mechanism 1, ensuring that the lifting and rotating mechanism 2 will not affect the translation of objects by the translation mechanism 1.

[0045] Specifically, Figure 4 , Figure 5 As shown, the flip mechanism 3 includes a fixed portion 31 and a movable support plate 32 hinged on the fixed portion 31; the end of the movable support plate 32 away from the translation mechanism 1 is vertically fixedly connected to a flip tray 33; the flip mechanism 3 also includes a telescopic mechanism, one end of which is connected to the support frame 4, and the other end is connected to the position of the movable support plate 32 away from the hinge point, and the movable support plate 32 and the flip tray 33 as a whole can be flipped around the first hinge shaft 34. The other end of the telescopic mechanism can be hinged to any side of the movable support plate 32 away from the first hinge shaft 34.

[0046] The telescopic mechanism includes a lead screw 36 driven by a lead screw motor 35, a lead screw nut matched with the lead screw 36, a slider 39 slidably connected to the slide rail on the support frame 4 and fixedly connected to the lead screw nut, and a support link 37 with one end hinged on the slider 39; the support link 37 is hinged to the slider 39 through a second hinge shaft 38; the other end of the support link 37 is hinged to the bottom surface of the movable support plate 32. The support link 37 is used to drive the movable support plate 32 to flip, that is, the support link 37 can drive the movable support plate 32 and the flip tray 33 to flip as a whole. The lead screw nut cooperates with the lead screw 36 to drive the movable support plate 32 to flip, and cooperates with the slide rail on the support frame 4 to provide support force for the flip mechanism 3 to flip the cabinet to be welded, so as to avoid the support pressure of the flip mechanism 3 being borne by the lead screw 36.

[0047] There are two sliders 39, which are respectively fixedly connected to the two sides of the lead screw nut and slidably connected to the two slide rails of the support frame 4, and there are also two corresponding support connecting rods 37. The two sliders 39 support the movable support plate 32 to ensure the stability of the support. One or two sliders 39 can support the movable support plate 32 and ensure that the flip mechanism flips the cabinet to be welded normally.

[0048] The translation mechanism 1 includes a roller 11 which drives the cabinet to be welded to translate by rolling. The roller 11 is mounted on the upper surface of one side edge of the support frame 4 .

[0049] like Figure 6-9 As shown, the lifting and rotating mechanism 2 includes a rotating tray 22 for driving the cabinet to be welded to rise, fall and rotate, and also includes a piston cylinder 23 for pushing up and pulling down. Preferably, the piston cylinder 23 is a gas cylinder.

[0050] In order to ensure the smooth rise and fall of the rotating tray 22, a fixed plate 21 is fixedly arranged on the upper surface of the cylinder body of the piston cylinder 23 for driving the rotating tray 22 to rise and fall, and a guide rod 24 provided for guiding and sliding on the plate body of the fixed plate 21 is connected to the rotating tray 22 to ensure the verticality of the lifting. That is, the guide rod 24 is arranged parallel to the power shaft 25 of the cylinder 23.

[0051] In order to ensure that a large cabinet can also be smoothly driven to rise, fall and rotate, a bracket 26 for supporting the cabinet to be welded is also provided on the rotating tray 22. In order to save material for the bracket 26, the bracket 26 is a rotationally symmetrical single-rod bracket 26.

[0052] Working principle: Take welding a rectangular open cabinet as an example to illustrate. The welding materials include two small square plates and one large long hair-shaped plate. The small square is used as the front and back sides of the cabinet, and the large rectangle is used as the left, right and bottom sides of the cabinet. Generally, a mechanical arm or a human being is located on one side of the support frame to weld the cabinet. The spot-welded cabinet is placed on the translation mechanism 1 of the support frame, and is moved to the mobile support plate 32 through translation. The screw motor 35 drives the screw 36 to further drive the support link 37 to make the mobile support plate 32 and the flip tray 33 flip 90 degrees to the right. During the flipping process, the flip tray 33 supports the cabinet. After the flipping is completed, the flip tray 33 provides support for the cabinet. Fully weld one side of the cabinet. After the welding is completed, the screw motor 35 drives the screw 36, and further drives the support link 37 to drive the mobile support plate 32 and the flip tray 33 to flip 90 degrees to the right. The cabinet is supported by the mobile support plate 32, and the cabinet is driven to translate to the jacking and rotating mechanism 2 through the rolling bars 11 on both sides of the support frame. The cylinder 23 of the lifting and rotating mechanism drives the fixed plate 21 to rise, driving the cabinet to rise away from the plane where the translation mechanism 1 is located, and manually pushes the rotating tray 22 to rotate, driving the cabinet to rotate 90 degrees. The cylinder 23 drives the cabinet to descend through the fixed plate 21, and the translation mechanism 1 drives the cabinet to translate onto the movable support plate 32. The flipping mechanism 3 drives the cabinet to flip 90 degrees. At this time, the other side of the cabinet is located on the side where welding can be performed. This side of the cabinet is fully welded to complete the welding of the cabinet. When setting up the support frame, it can be adjusted in accordance with the position of the robot arm. After adjusting once, the cabinet can be batch welded without adjusting the position of the support frame or the robot arm again. Improve the efficiency of welding.

[0053] Finally, it should be noted that the above is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments without creative work, or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
