Description

Technical Field

[0001] This utility model belongs to the field of welding equipment technology, specifically relating to a welding equipment suitable for lifting machine outriggers. Background Technology

[0002] In modern manufacturing, lifts are important pieces of machinery widely used in construction, logistics, and maintenance. The outrigger structure is a core component of the lift, undertaking the crucial functions of lifting and supporting. Therefore, the welding quality and efficiency requirements for the outrigger are extremely high. However, traditional outrigger welding processes have some shortcomings, affecting both production efficiency and welding quality.

[0003] In manual mode, the parts are shaped by manual tooling or fixtures, then spot-welded in sequence, and the welding operation is carried out manually throughout the process according to the process and manufacturing requirements until the parts are welded.

[0004] The main reasons for this phenomenon are the changes in the material form of the single-column lift components, the weight of the components, and the shrinkage and deformation during the welding process. These factors mean that traditional methods cannot effectively meet the problems of fully welded finished products and compatible co-production of different products of the same type on the same line. Therefore, a lift arm welding device is needed to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a welding equipment suitable for lifting booms, which solves the above-mentioned technical problems existing in the prior art.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A welding device for lifting booms includes a welding station, a load-bearing station, a first load-bearing fixture, and a second load-bearing fixture.

[0008] The bearing station is divided into two groups arranged symmetrically from left to right. A rotating seat is set at one end of the U-shaped structure where the bearing station is located. A first bearing fixture is connected to one group of rotating seats, and a second bearing fixture is connected to the other group of rotating seats, so as to realize the independent deflection of the first bearing fixture and the second bearing fixture respectively.

[0009] The first bearing fixture has an overall "I" shaped structure. A positioning pin is set at the bottom of the first bearing fixture. Several sets of locking buckles are set on the side of the positioning pin. The locking buckles form a locking and fixing of the support arm to be welded by the hinge of the positioning pin and the support arm to be welded.

[0010] The second bearing fixture has an overall U-shaped structure, which allows the support arm to be welded to be engaged in the U-shaped groove of the second bearing fixture;

[0011] The welding stations are respectively moved to the first bearing fixture and the second bearing fixture to form the welding of the support arm to be welded.

[0012] Furthermore, the welding station includes a bottom slide and a top welding robot, so that the bottom of the welding robot slides along the extension direction of the slide to the station where the first bearing fixture and the second bearing fixture are located.

[0013] Furthermore, a drive gear is provided at the bottom of the welding robot, and parallel racks are provided along the extension direction of the slide, so that the output end of the drive gear meshes with the rack for transmission.

[0014] Furthermore, multiple sets of connecting holes are provided on the end face of the rotating seat to ensure that the connecting holes are evenly distributed on the end face of the rotating seat. At the same time, an L-shaped connecting seat is provided on the end face of the rotating seat so that the end face of the L-shaped connecting seat is fixed to the rotating seat through the connecting holes and simultaneously deflects with the rotating seat.

[0015] Furthermore, the first and second load-bearing clamps are bolted to the outriggers extending from the L-shaped connecting seat.

[0016] Furthermore, the two sets of bearing stations are separated by baffles, making the first bearing fixture and the second bearing fixture independent.

[0017] Furthermore, the locking buckle on the first bearing fixture is hydraulically driven.

[0018] Furthermore, a limiting block is provided on the bottom side of the second bearing fixture, which forms a side limit for the bearing arm to be welded; at the same time, a limiting buckle is provided in the vertical direction, which forms a vertical limit for the bearing arm to be welded.

[0019] The beneficial effects of this utility model are:

[0020] 1. The bearing stations of this device are symmetrically arranged on the left and right sides, which can process two sets of support arms to be welded at the same time, thus improving work efficiency; and the combination of the rotating seat and the L-shaped connecting seat allows the welding device to adapt to different models of support arms, making it easy to replace and adjust.

[0021] 2. The welding robot used in this device moves along the slide rail at the welding station, enabling precise positioning of the first and second support fixtures to weld the two sets of support arms. Through the meshing of the drive gear and rack, the movement of the welding robot is more stable, ensuring the stability and accuracy of the welding process.

[0022] 3. The first load-bearing fixture of this device adopts an "I"-shaped structure, equipped with positioning pins and locking buckles, which can firmly lock the support arm to be welded and adapt to the clamping requirements of heavy weights. The U-shaped structure design of the second load-bearing fixture simplifies the installation process. The support arm to be welded can be placed directly without additional locking steps, thus improving operating efficiency. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0030] like Figure 1 , Figure 2 As shown, this utility model embodiment provides a welding equipment suitable for lifting booms, including a welding station 1, a bearing station 2, a first bearing fixture 3, and a second bearing fixture 4.

[0031] The bearing station 2 is divided into two groups arranged symmetrically on the left and right. At this time, the welding station 1 is located on one side, which can form the welding of the support arm parts to be welded on the two groups of bearing stations 2.

[0032] Welding station 1 includes a bottom slide rail 11 and a top welding robot 12. The bottom of the welding robot 12 slides along the extension direction of the slide rail 11 to the station where the first bearing fixture 3 and the second bearing fixture 4 are located, and then the support arm to be welded held by the fixture is welded.

[0033] To ensure the stability of the welding robot 12 during movement, a drive gear 13 is installed at the bottom of the welding robot 12, and parallel racks 14 are installed along the extension direction of the slide rail 11. The output end of the drive gear 13 meshes with the racks 14 to achieve transmission. That is, through the output of the drive gear 13, the welding robot 12 can move as a whole along the extension direction of the racks 14 (i.e., the same extension direction as the slide rail 11).

[0034] like Figure 3 As shown, a rotating seat 21 is provided at one end of the U-shaped structure where the bearing station 2 is located. Multiple sets of connecting holes 211 are provided on the end face of the rotating seat 21 to achieve the even distribution of the connecting holes 211 on the end face of the rotating seat 21. At the same time, an L-shaped connecting seat 22 is provided on the end face of the rotating seat 21, so that the end face of the L-shaped connecting seat 22 is fixed to the rotating seat 21 through the connecting holes 211 (at this time, the end face of the L-shaped connecting seat 22 is also provided with connecting holes 211), and the deflection of the rotating seat 21 is realized simultaneously (this deflection method is not rotation, but left and right swinging method, and its main welding point is on the upper surface. The left and right swinging method can meet the welding requirements). Since the L-shaped connecting seat 22 and the rotating seat 21 are connected by bolts through connecting holes 211, the L-shaped connecting seat 22 can be replaced according to different models of the support arm to be welded.

[0035] Similarly, the first bearing fixture 3 and the second bearing fixture 4 are bolted to the support arm extending from the L-shaped connecting seat 22, and can also be fixed by bolts, which is convenient for replacement when welding different parts.

[0036] Since the bearing station 2 is set with two sets, that is, there are two sets of rotating seats 21, and the first bearing fixture 3 is connected to one set of rotating seats 21, and the second bearing fixture 4 is connected to the other set of rotating seats 21, so that the first bearing fixture 3 and the second bearing fixture 4 can be independently deflected respectively.

[0037] The two sets of bearing stations 2 are separated by a baffle 5, which makes the first bearing fixture 3 and the second bearing fixture 4 independent. Therefore, during welding and assembly, the support arms to be welded on the first bearing fixture 3 and the second bearing fixture 4 do not affect each other, avoiding mutual interference during the welding process and improving the efficiency of welding and assembly.

[0038] like Figure 4As shown, the first bearing fixture 3 has an overall "I" shaped structure. At the bottom of the first bearing fixture 3, a positioning pin 301 is set. The positioning pin 301 can lock with the through hole on the support arm to be welded (improving the assembly effect and convenience of the support arm to be welded on the first bearing fixture 3). Several sets of locking buckles 302 are set on the side of the positioning pin 301. Through the hinge between the positioning pin 301 and the support arm to be welded, the locking buckles 302 form a locking and fixing of the support arm to be welded. The locking buckles 302 on the first bearing fixture 3 are hydraulically driven. This driving method can achieve greater pressure and meet the clamping requirements of heavy support arms to be welded.

[0039] like Figure 5 As shown, the second bearing fixture 4 has a U-shaped structure, allowing the support arm to be welded to be engaged in the U-shaped groove of the second bearing fixture 4. The support arm can be placed directly in the U-shaped groove without the need for a separate locking process similar to the locking buckle 302 of the first bearing fixture 3, thus improving its installation and fixing effect. Therefore, a limiting block 401 is provided on the bottom side of the second bearing fixture 4 to limit the side of the support arm to be welded; simultaneously, a limiting buckle 402 is provided in the vertical direction to limit the vertical direction of the support arm to be welded. By using the limiting block 401 and the limiting buckle 402 to lock the support arm to be welded on the side and vertically, respectively, the necessary deflection displacement of the support arm to be welded can be reduced when the second bearing fixture 4 undergoes deflection movement.

[0040] Furthermore, the welding station 1 used simultaneously performs welding operations on the support arm parts to be welded on the first bearing fixture 3 and the second bearing fixture 4, which greatly improves the welding efficiency of the entire tooling.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
