Description

Technical Field

[0001] This utility model relates to the field of hydraulic oil tank processing technology, and more specifically, to a high-efficiency welding device for hydraulic oil tanks. Background Technology

[0002] The hydraulic oil tank is a component in the hydraulic system of an excavator used to store hydraulic fluid. The outer shell of the hydraulic oil tank is formed by a bottom plate, side plates, and a top plate. In order to allow the hydraulic oil to cool down and dissipate heat during operation, and also to allow sufficient time for air bubbles to precipitate, baffles are welded inside the hydraulic oil tank. Multiple baffles are arranged alternately to form a tortuous channel for the hydraulic oil to flow, which can prolong the flow path of the hydraulic oil and reduce the circulation speed of the hydraulic oil.

[0003] When welding the outer shell of the hydraulic oil tank, workers use handheld welding guns. In the existing technology, the bottom plate, side plates and other components lack reliable and effective support and positioning during welding, which cannot guarantee welding accuracy. The shape and size of the welded hydraulic oil tank are significantly different from the design drawings, affecting the aesthetics of the product. When the deformation is large, it may even interfere with other parts during installation, affecting the normal assembly of the product.

[0004] Announcement No. CN217942355U proposes a welding positioning fixture for hydraulic oil tanks. This device can support and position parts during welding, ensuring welding accuracy and making the shape and size of the finished hydraulic oil tank meet the usage requirements. On the other hand, the magnetic fixing method can quickly attract and fix the parts, which is more convenient to operate compared with other clamping methods. However, this device cannot achieve accurate alignment in one go during the adsorption and docking process between the side plate and the bottom plate of the hydraulic oil tank, and repeated adjustments consume time. The welding positioning effect needs to be further improved. Utility Model Content

[0005] The purpose of this invention is to solve the problems mentioned in the background art and to propose a high-efficiency welding device for hydraulic oil tanks.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A high-efficiency welding device for hydraulic oil tanks includes a welding table, a first positioning groove adapted to the placement of a base plate and symmetrically distributed telescopic components on the welding table, a first electromagnetic plate disposed in the first positioning groove, and two opposing positioning tables connected to the telescopic components via connecting rods, the positioning tables being provided with concave holes adapted to the shape of side plates and a second positioning groove, and a second electromagnetic plate disposed in the second positioning groove.

[0008] This device can achieve accurate alignment between the hydraulic tank bottom plate and side plate with a single installation and adsorption, eliminating the need for repeated adjustments and saving time and cost associated with the connection process, resulting in a better overall welding effect.

[0009] Furthermore, each of the two positioning platforms is equipped with an infrared transmitter, and two infrared receivers are symmetrically arranged on the welding platform. The infrared transmitters and infrared receivers cooperate with each other and are electrically connected.

[0010] The above scheme uses an infrared transmitter and an infrared receiver to achieve accurate movement of the positioning stage so that the concave hole on the positioning stage is accurately aligned with the side wall of the first positioning groove.

[0011] Furthermore, a buzzer is provided on the welding platform, and the buzzer is electrically connected to the infrared receiver.

[0012] In the above scheme, after the signal emitted by the infrared transmitter is collected by the infrared receiver, the controller simultaneously sends a signal back to the buzzer and the telescopic assembly. At this time, the buzzer sounds to inform the welding personnel that the side panel can be inserted.

[0013] Furthermore, the welding station is connected to a drive assembly.

[0014] Furthermore, the drive assembly includes a mounting base, a servo motor, a main gear, a support roller, and a secondary gear. The support roller is rotatably connected to the mounting base and the servo motor is fixedly mounted thereon. The servo motor is connected to the main gear, and the main gear meshes with the secondary gear provided on the support roller. One end of the support roller is connected to a welding station.

[0015] The above solution can automatically change the position of the hydraulic oil tank during the welding process by driving the welding table to rotate, eliminating the need for frequent manual movement and thus reducing the labor intensity during the welding process.

[0016] Furthermore, the telescopic component is either an electric cylinder or an electric push rod.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] Compared to existing technologies, this device only requires one installation and magnetic adsorption to achieve accurate alignment between the hydraulic tank bottom plate and the side plate. It eliminates the need for repeated adjustments to the orientation, saving time and costs associated with the connection process. The overall welding effect is better and smoother, making it suitable for assembly line welding operations. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. 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. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0025] like Figures 1 to 3 As shown, a high-efficiency welding device for hydraulic oil tanks includes a welding table 1. The welding table 1 is provided with a first positioning groove 11 for placing a base plate and adapted to the length and width of the base plate, and symmetrically distributed telescopic components. Specifically, the telescopic components are either an electric cylinder 13 or an electric push rod. A first electromagnetic plate 12 is provided in the first positioning groove 11. The telescopic components are connected to two opposing positioning platforms 15 through a connecting rod 14. It should be noted that the connecting rod 14 is L-shaped and connects to the side of the positioning platform 15. This design is intended to leave operating space for subsequent welding personnel and ensure the subsequent welding operation. The positioning platform 15 is provided with a concave hole 16 adapted to the shape of the side plate and a second positioning groove 17. A second electromagnetic plate 18 is provided in the second positioning groove 17. It should be noted that the surface of the second electromagnetic plate 18 is flush with the inner wall of the positioning platform 15.

[0026] It should be noted that the first electromagnetic plate 12, the second electromagnetic plate 18, and the telescopic assembly are all electrically connected to the controller, which is not shown in the figure.

[0027] The working process of this utility model:

[0028] The side and bottom plates of the hydraulic oil tank adopt the same shape as those in the hydraulic oil tank welding positioning fixture proposed in announcement number CN217942355U, without modification. Before the initial welding process, the controller controls two telescopic components to move the two positioning platforms 15 synchronously away from the first positioning groove 11. The two positioning platforms 15 maintain a symmetrical state and move collaboratively. Then, the bottom plate of the hydraulic oil tank is placed in the first positioning groove 11. After placement, the controller controls the first electromagnetic plate 12 to be energized, thus completing the adsorption and positioning of the hydraulic oil tank bottom plate. At this time, the upper surface of the bottom plate is higher than the first positioning groove 11 to avoid obstructing subsequent welding with the side plates. After the bottom plate is adsorbed and positioned, the controller controls the two sets of telescopic components to move synchronously towards the center. When the concave hole 16 on the positioning platform 15 is aligned with the side wall of the first positioning groove 11, the controller controls the telescopic components to stop working, and then... The two side plates are vertically inserted into the concave holes 16 on both sides one after the other. During the insertion process, the side plates are kept in contact with the positioning table 15. When the lower end of the side plate contacts the bottom plate, the controller controls the second electromagnetic plate 18 to be energized, which can limit the position of the two side plates. At this time, the two side plates are in contact and accurately aligned with the bottom plate. It should be noted that after the side plates are adsorbed and positioned in the concave holes 16, they are higher than the positioning table 15. Then, the welding can be carried out manually with a welding gun. At this time, there is a welding space between the positioning table 15 and the welding table 1 for easy operation. After the welding is completed, the controller first controls the second electromagnetic plate 18 to be de-energized. Then, the two sets of telescopic components move away synchronously under the control of the controller to detach from the side plates. Then, the controller controls the first electromagnetic plate 12 to be de-energized, so that the bottom plate and the side plates can be removed together. At this time, the accurate welding between the hydraulic oil tank bottom plate and the side plates is completed.

[0029] Compared to existing technologies, this device can achieve accurate alignment between the hydraulic tank bottom plate and side plate with a single installation and adsorption, eliminating the need for repeated adjustments and saving time and cost associated with the connection process, resulting in a better overall welding effect.

[0030] In some embodiments, such as Figure 3 As shown, infrared transmitters 3 are respectively installed on two positioning platforms 15, and two infrared receivers are symmetrically arranged on the welding platform 1. The infrared receivers are not shown in the figure. The infrared transmitters 3 and infrared receivers cooperate and are electrically connected. In this embodiment, the infrared transmitters 3 and infrared receivers can achieve accurate movement of the positioning platform 15 so that the concave hole 16 on the positioning platform 15 is accurately aligned with the side wall of the first positioning groove 11. The alignment effect is good and the error is very small and negligible.

[0031] Further optimizations of the above-described embodiments, such as... Figure 3As shown, a buzzer 4 is installed on the welding table 1. The buzzer 4 is electrically connected to the infrared receiver. In this embodiment, after the signal emitted by the infrared transmitter 3 is collected by the infrared receiver, the controller simultaneously feeds back a signal to the buzzer 4 and the telescopic component. At this time, the buzzer 4 sounds to inform the welding personnel that the side plate can be inserted.

[0032] In other embodiments, such as Figure 1 As shown, it also includes a mounting base 2, on which a support roller 23 is rotatably connected via a bearing and a servo motor 21 is fixedly mounted. The servo motor 21 is connected to a main gear 22, which meshes with a secondary gear 24 on the support roller 23. One end of the support roller 23 is connected to a welding table 1. In this embodiment, by driving the welding table 1 to rotate, the orientation of the hydraulic oil tank can be automatically changed during the welding process, eliminating the need for frequent manual movement and thus reducing the labor intensity during the welding process.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
