Description

Technical Field

[0001] This utility model relates to a lifting device, and more particularly to a lifting device for a welding robot. Background Technology

[0002] Welding is an essential process in modern machinery manufacturing, widely used in vehicle production. To achieve more efficient machining, intelligent products are integrated with existing structures in processing workshops, especially with the development of welding automation, leading to the increasingly widespread use of welding robots. Furthermore, welding robots are often paired with wire feeders for material transport. To adapt to different applications, the mechanical interface of the robot's last axis is typically a connecting flange, which can be fitted with various tools or end effectors. Welding robots are essentially industrial robots with welding clamps or welding (cutting) torches mounted on the flange of their last axis, enabling them to perform welding, cutting, or thermal spraying.

[0003] Currently, to facilitate the installation, movement, and maintenance of welding robots, they are often lifted using a lifting device, with the wire feeder integrated into the device. This facilitates both the robot's relocation and welding operations. However, the existing method is incompatible with different installation configurations, offering limited options for both the robot and the wire feeder, which hinders the processing of various welding products. Therefore, it is necessary to design a lifting device for welding robots with multi-directional connection points to facilitate the processing of different welding products. Utility Model Content

[0004] In view of the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a lifting device for welding robots, which realizes the purpose of welding robots having multi-directional connection ends, facilitating the processing of different welding products.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A lifting device for a welding robot includes a lifting device body, a lifting device cover fitted over the lifting device body, a wire feeding base on the lower side of the lifting device body, a vertical suction plate parallel to the wire feeding base in the middle of the lifting device body, a side mounting plate on the top of the vertical suction plate, and a lifting clamp fitted over the side mounting plate for vertical and side mounting of the robot.

[0007] Preferably, the top of the wire feeding base is vertically provided with a wire feeding taper seat, the middle of the wire feeding taper seat is provided with a through seat, and the middle of the through seat is provided with a through cone for mounting a wire feeder.

[0008] Preferably, the vertical mounting suction plate includes an electromagnet, and a limiting opening is provided on the vertical mounting suction plate for vertically mounting the robot.

[0009] Preferably, the side mounting plate includes adjacent side plates and limiting seats, and the top of both the side plates and the limiting seats is provided with arc-shaped grooves for circumferential limiting of the robot.

[0010] Preferably, a compression airbag is provided in the arc-shaped groove at the top of the limiting seat, and limiting blocks are slidably provided at both ends of the top of the limiting seat, with the limiting blocks communicating with the compression airbag.

[0011] Preferably, the lifting clamp includes a connecting plate connected to the side mounting plate, a retaining ring is provided on one side of the connecting plate, and connecting plates are provided on both sides of the end of the retaining ring away from the connecting plate.

[0012] Preferably, the lower end of the side panel is provided with a spacing adjustment component, which includes two parallel slide rails, and a secondary limiting component is slidably mounted on the two slide rails.

[0013] Preferably, the secondary limiting component consists of two clamps used in conjunction with each other. The two clamps have the same structure as the side mounting plate and the lifting clamp, respectively, and are used for the side mounting stability of the robot.

[0014] Compared with existing technologies, the lifting device for welding robots provided by this utility model can be installed vertically or sideways on the welding robot and can also fix the wire feeder, facilitating the processing of different welding products. Specifically, the electromagnetic switch of the vertical suction plate can be easily connected to the magnet at the bottom of the robot to achieve vertical positioning of the robot; the side-mounted plate and lifting clamp can be easily fitted onto the outside of the robot, allowing the robot to be used on its side, achieving multi-directional connection and increasing the diversity of welding products.

[0015] Furthermore, the use of the side plate and limiting seat on the side mounting plate facilitates the compression of the airbag during robot side mounting, allowing the limiting block to limit the robot's sides. The use of the lifting clamp on the side mounting plate facilitates the clamping of the robot from top to bottom, achieving side mounting limitation of the robot. Subsequently, the use of the spacing adjustment component and the secondary limiting component facilitates the use of the secondary limiting component with the same structure as the side plate and the lifting clamp, which not only limits the side-mounted robot but also expands the fastening range, improves the stability between the side-mounted robot and the lifting device, and facilitates the subsequent position movement of the lifting device. In addition, the use of the wire feeding tap seat in conjunction with the taper sleeve on the wire feeder is very beneficial for fixing the position of the wire feeder.

[0016] It should be understood that the general descriptions and details herein are exemplary and illustrative only and are not intended to limit this disclosure.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the embodiments of this disclosure will be described in more detail below with reference to the accompanying drawings. Note: The described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0026] As attached Figure 1 To be continued Figure 5As shown in the embodiment of this utility model, the lifting device for welding robots is currently used for handling welding robots when processing at different workstations. The existing lifting device for welding robots includes a lifting device body for fixing the position of the robot and the wire feeder. Then, a lifting device cover 11 is fitted on the outside of the lifting device body. The lifting device cover 11 can be a transparent soft PVC cover to seal the periphery of the lifting device body. It can also be lifted to prevent dust and water droplets. A wire feeder base 12 is set on the lower side of the lifting device body to install the wire feeder. By setting a vertical suction plate 3 parallel to the wire feeder base 12 in the middle of the lifting device body, it is convenient to install the welding robot vertically in the lifting device. Then, a side mounting plate 4 is set on the top of the vertical mounting plate 3. The lifting clamp 5 is fitted on the outside of the side mounting plate 4. The cooperation of the side mounting plate 4 and the lifting clamp 5 facilitates the vertical and side installation of the robot, providing convenience for the use of the welding robot at different workstations.

[0027] It is worth noting that, when the wire feeder is installed on the main body of the lifting device, in order to achieve a stable installation of the lifting device and the wire feeder, such as... Figure 1 and 2 As shown, a wire feeding cone seat 2 can be vertically installed on the top of the wire feeding base 12. A through seat 21 is installed in the middle of the wire feeding cone seat 2. A through cone 22 is installed through the middle of the through seat 21. A cone sleeve can be installed through the lower end of the wire feeder. By connecting the cone sleeve with the wire feeding cone seat 2, the through seat 21 and the cone sleeve of the wire feeder can be engaged to ensure the installation position of the wire feeder.

[0028] In some embodiments, the vertical suction plate 3 may be equipped with an electromagnet on its plate body, and the electromagnet is externally connected to a power source. Similarly, a magnetic metal plate is also provided at the bottom of the welding robot. Using existing electromagnetic adsorption technology, the vertical suction plate 3 can be magnetically adsorbed with the magnetic metal plate on the welding robot, so that the welding robot is limited on the lifting device. With the limiting port 31 opened on the vertical suction plate 3, the welding robot can be vertically limited, which makes it convenient for the lifting device to use the welding robot in a normal position.

[0029] It is worth noting that, in order to facilitate the side-mounted use of the welding robot, such as Figure 1 As shown, the side mounting plate 4 is located next to the vertical suction plate. In some embodiments, it can also be rotatably mounted on the main body of the lifting device. The side mounting plate 4 can use the adjacent side plate 41 and the limiting seat 42. Furthermore, the top of the side plate 41 and the limiting seat 42 are provided with arc-shaped grooves for the side of the welding robot to fit, thereby limiting the circumferential movement of the welding robot and adding the side mounting function of the lifting device to facilitate the side welding of the welding robot.

[0030] To facilitate the stable use of side-mounted welding robots, such as Figure 4As shown, in some embodiments, a compression airbag 421 can be provided in the arc-shaped groove at the top of the limiting seat 42, and limiting blocks 422 can be slidably provided at both ends of the top of the limiting seat 42. The limiting blocks 422 are connected to the compression airbag 421. In the initial state of the limiting seat 42, the limiting blocks 422 are retracted in the limiting seat 42. When the welding robot is installed on the side, the welding robot will squeeze the compression airbag 421 to deform it. The gas in the compression airbag 421 can push the limiting blocks 422 out of the limiting seat 42 to limit and fix the left and right sides of the welding robot, ensuring the stability of the welding robot when connected to the lifting device.

[0031] Furthermore, in order to stably hoist and move the side-mounted welding robot, such as... Figure 3 and 5 As shown, the lifting clamp 5 can be connected to the connecting plate 51 through the outside of the side mounting plate 4 using bolts. Then, a retaining ring 52 is set on one side of the connecting plate 51. The middle part of the retaining ring 52 has an arc-shaped structure and is located on the upper side of the limiting seat 42. Connecting plates 521 are set on both sides of the end of the retaining ring 52 away from the connecting plate 51. The connecting plates 521 and the retaining ring 52 have an inverted U-shaped structure. The lower end of the connecting plates 521 is connected to the main body of the lifting device to realize the limiting treatment of the welding robot in the vertical direction.

[0032] Furthermore, in some embodiments, to ensure the welding robot is more stably mounted on the lifting device body, such as... Figure 1 and 3 As shown, a spacing adjustment component 6 can be provided at the lower end of the side mounting plate 4. The spacing adjustment component 6 uses two parallel slide rails 61, and the same secondary limiting component 62 slides on the two slide rails 61. Through the cooperation of the secondary limiting component 62 and the limiting seat 42, the connection strength of the welding robot on the lifting device body can be increased.

[0033] To increase the processing cost of the lifting device, the secondary limiting component 62 can use the same structure as the side mounting plate 4 and the lifting clamp 5, such as... Figure 3 As shown, the secondary limiting component 62 consists of two clamps. The two clamps have the same structure as the side mounting plate 4 and the lifting clamp 5, respectively. With the cooperation of the side mounting plate 4 and the lifting clamp 5, they can be side-mounted on the outside of the welding robot's base at the same time, ensuring the stable side mounting of the welding robot and improving the functional effect of the lifting device on the welding robot.

[0034] Of course, the above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
