Description

Technical Field

[0001] This utility model belongs to the field of welding robots, and in particular relates to a parts processing device for industrial welding robots. Background Technology

[0002] Welding robots are industrial robots that perform welding (including cutting and spraying). According to the International Organization for Standardization (ISO) definition of a standard welding robot, an industrial robot is a multi-purpose, reprogrammable, automated manipulator with three or more programmable axes used in industrial automation. To adapt to different applications, the mechanical interface of the robot's last axis is typically a connecting flange, which can be used to attach different tools or end effectors. Therefore, a welding robot is an industrial robot with a welding clamp or welding (cutting) torch mounted on its last axis flange, enabling it to perform welding, cutting, or thermal spraying operations.

[0003] Currently, welding robots require the use of fixtures to clamp the parts being processed when welding. Conventional fixtures typically place the parts on a loading plate and then use clamping blocks to hold them in place. However, this means that the side of the part that is in contact with the loading plate cannot be welded in one go. To avoid the time-consuming and laborious process of flipping the parts over and continuing the welding, a processing device that can weld in one go is needed to reduce workload and improve welding quality and efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a parts processing device for industrial welding robots, which can reduce labor intensity and improve welding quality and efficiency.

[0005] The aforementioned industrial welding robot parts processing device includes a loading plate with an upper and lower communicating mounting groove. Several sliders, arranged horizontally and slidingly with the loading plate, are disposed within the mounting groove. A fixing groove without an upper wall is formed on the rear side wall of the mounting groove. Loading holes, communicating vertically, are formed on the lower walls of both the loading plate and the fixing groove. A connecting plate integrally formed with the sliders is disposed within the fixing groove. The connecting plate also has loading holes that, after sliding, are concentric with the loading holes in the fixing groove. A retaining assembly for fixing the connecting plate within the fixing groove and for fixing the position of the parts is detachably mounted on the loading plate. The device also includes a driving assembly for driving the loading plate to rotate at a certain angle.

[0006] Furthermore, the retaining component includes a fixing block, a threaded rod fixed to the bottom of the fixing block, a nut threadedly fitted onto the threaded rod, a connecting rod with a threaded lower end vertically arranged above the fixing block, the lower end of the connecting rod passing through the fixing block and threadedly fitted thereto, a mounting plate provided on one side of the connecting rod, one end of the mounting plate fitted onto the upper end of the connecting rod and rotatably fitted thereto, and a pressing block fixed to the bottom of the other end of the mounting plate.

[0007] Furthermore, a limiting plate is fixed on the connecting rod to prevent the mounting plate from moving up and down.

[0008] Furthermore, the pressing block is made of rubber.

[0009] Furthermore, a retaining ring is fixed to the top of the connecting rod.

[0010] Furthermore, there are two mounting slots distributed front to back, and the rear wall of the front mounting slot and the front wall of the rear mounting slot are both fixed with slide rails to restrict the slider to slide only left and right.

[0011] Furthermore, the drive assembly includes two mounting columns located on the left and right sides of the loading plate, respectively. Clamping plates are fixed at both the left and right ends of the loading plate. A drive motor is installed in the mounting column on the right side, and the power output end of the drive motor is connected to the clamping plate at the right end of the loading plate. A bearing seat is installed in the mounting column on the left side, and the clamping plate at the left end of the loading plate is installed in the bearing seat through a bearing.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention utilizes a slider that can slide freely left and right within the mounting slot of the loading plate. This slider not only supports the components but also fully exposes the welding areas of the components after sliding, facilitating welding robots to weld various components. The detachable fixing component secures the slider's position while fixing the component, and this detachable design prevents components from being unable to be placed. Furthermore, this embodiment uses a drive component to rotate the loading plate 180°, so that the unwelded parts of the components face upwards, eliminating the need for secondary clamping and allowing welding to be completed in one operation. This also avoids distance deviations caused by secondary clamping. Therefore, this device not only reduces the labor intensity of operators but also improves the efficiency and quality of welding processes. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention. Example

[0021] This embodiment describes a parts processing device for an industrial welding robot, including a loading plate 3. The loading plate 3 has a vertically connected mounting groove. Several sliders 4, arranged horizontally and sliding left-right with the loading plate 3, are disposed within the mounting groove. In this embodiment, the sliders 4, which can freely slide left and right within the mounting groove of the loading plate 3, provide support for the parts and fully expose the welding areas of the parts. Figure 5 As shown, this facilitates the welding robot's welding processing of parts; such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, there are two mounting slots distributed front and back. The rear wall of the front mounting slot and the front wall of the rear mounting slot are both fixed with slide rails 5 to restrict the slider 4 to slide only left and right. Multiple mounting slots can effectively reduce the dead angles that cannot be fully exposed for welding, thereby increasing the range of parts that this device can process. A slide groove for the slide rail 5 to be engaged is provided on one side of the slider 4.

[0022] The rear side wall of the mounting groove has a fixing groove without an upper groove wall. Both the loading plate 3 and the lower groove wall of the fixing groove have vertically connected loading holes 7. In this embodiment, the loading holes 7 allow for the installation of other structures using bolts and other fasteners, while also reducing the actual volume of the loading plate 3, thus saving costs. Figure 2 and Figure 5 As shown, the loading plate 3 and the lower wall of the fixing groove are arranged in a rectangular array, and the distance between adjacent loading holes 7 is the same;

[0023] A connecting plate 10 integrally formed with the slider 4 is provided in the fixing groove. The connecting plate 10 is also provided with a loading hole 7 that can slide and be concentric with the loading hole 7 in the fixing groove. Figure 1 As shown, in this embodiment, the connecting plate 10, which has a loading hole 7 that can slide and be concentric with the loading hole 7 in the fixed groove, can fix the connecting plate 10 in the fixed groove with bolts or other tools after sliding to the appropriate position, so that the position of the slider 4 is fixed. It can also remove the slider 4 upwards, so that more space is exposed in the mounting groove, so as to ensure that the welding parts of the components can be fully exposed.

[0024] like Figure 1 , Figure 2 and Figure 5 As shown, the width of slider 4 in this embodiment has various specifications, so that it can be reasonably selected according to the shape, size and quantity of the parts in actual application, thereby further reducing the dead corners that cannot be fully exposed for welding and making the range of parts that this device can process wider.

[0025] A fixing block 9.1 is provided on the top of the loading plate 3. A threaded rod 9.2 is fixed to the bottom of the fixing block 9.1. A nut with a threaded engagement is fitted on the threaded rod 9.2. A connecting rod 9.5 with a threaded lower end is vertically provided above the fixing block 9.1. The lower end of the connecting rod 9.5 passes through the fixing block 9.1 and is threaded with it. A mounting plate 9.4 is provided on one side of the connecting rod 9.5. One end of the mounting plate 9.4 is fitted onto the upper end of the connecting rod 9.5 and is rotatably engaged with it. A pressing block 9.3 is fixed to the bottom of the other end of the mounting plate 9.4. (The fixing block 9.1, nut, threaded rod 9.2, pressing block 9.3, mounting plate 9.4, and connecting rod 9.5 in this paragraph constitute the retaining assembly 9 used to fix the connecting plate 10 in the fixing groove and to fix the position of the components.) In practical applications, the connecting rod 9.5 can also be a lead screw, with the mounting plate 9.4 fitted onto the lead screw and rotating with it. Two limiting nuts are fitted onto the lead screw, with one end of the mounting plate 9.4 fitted onto the connecting rod 9.5 positioned between the two limiting nuts. In this embodiment, by passing the threaded rod 9.2 at the bottom of the fixing block 9.1 through the loading hole 7 on the loading plate 3 or the loading hole 7 on the connecting plate 10 that is concentric with the loading hole 7 on the fixing groove, and then fitting and tightening the nuts, the fixing block 9.1 can be fixed onto the loading plate 3, or the position of the slider 4 can be fixed simultaneously. The detachable design avoids situations where parts cannot be placed. Furthermore, by rotating the connecting rod 9.5 and swinging the mounting plate 9.4, the pressing block 9.3 can press the parts against the loading plate 3 and the slider 4. Figure 1 , Figure 2 , Figure 3 and Figure 5 The connecting rod 9.5 is fixed with a limiting plate 12 to prevent the mounting plate 9.4 from moving up and down. There are two limiting plates 12, located at the top and bottom of the mounting plate 9.4 respectively. The pressing block 9.3 is made of rubber, which can prevent scratches or indentations from appearing on the surface of the parts.

[0026] In practical applications, the length of the mounting plate 9.4 and the height of the fixing block 9.1 are available in various specifications so that they can be reasonably selected according to the shape, size and quantity of the parts in practical applications. This avoids the situation where the parts cannot be pressed tightly against the loading plate 3 and the slider 4, and makes the range of parts that this device can process wider.

[0027] Mounting posts 1 are provided on both the left and right sides of the loading plate 3. Clamping plates 6 are fixed to both the left and right ends of the loading plate 3. A drive motor 2 is installed inside the mounting post 1 on the right side. The power output end of the drive motor 2 is connected to the clamping plate 6 at the right end of the loading plate 3. A bearing seat 8 is installed inside the mounting post 1 on the left side. The clamping plate 6 at the left end of the loading plate 3 is mounted in the bearing seat 8 via a bearing. (In this embodiment, the drive motor 2, bearing seat 8, two mounting posts 1, and two clamping plates 6 together constitute the drive assembly for driving the loading plate 3 to rotate at a certain angle. The drive motor 2 can be a servo motor or a stepper motor with a brake.) In this embodiment, the drive motor 2 can drive the loading plate 3 to rotate 180°, so that the side of the component with the welding part facing down faces up. Therefore, the welding process of the component can be completed in one go without secondary clamping of the component, and the distance deviation caused by secondary clamping is avoided. Thus, this device not only reduces the labor intensity of relevant operators but also improves the efficiency and quality of welding processing. Figure 1 and Figure 2 As shown, it also includes a rotating shaft, one end of which is fixed to the inner ring of the bearing, and the other end of the rotating shaft and the power output end of the drive motor 2 are both connected to the corresponding clamping plate 6 through a flange.

[0028] In this embodiment, the component is first placed on the loading plate 3 and slider 4, with the welding area within the mounting groove. Then, slider 4 is slid or removed, or a slider of a different specification is replaced until the welding area of ​​the component is fully exposed and has no direct contact with the device. Then, the threaded rod 9.2 at the bottom of the fixing block 9.1 is passed through the loading hole 7 on the loading plate 3 or the loading hole 7 on the connecting plate 10 that is concentric with the loading hole 7 on the fixing groove. The nut is then put on and tightened, fixing the position of slider 4. Then, the connecting rod 9.5 is rotated to move the mounting plate 9.4 up or down, while simultaneously rotating the mounting plate 9.4 to keep the pressing block 9.3 directly above the appropriate position of the component until the pressing block 9.3 presses the component against the loading plate 3 and slider 4. Then, the industrial welding robot is started to weld the five possible areas of the welding area: front, back, top, left, and right. After welding, the drive motor 2 is started to rotate the slide rail 5 180°, so that the unwelded parts of the welding area face upwards. Finally, the industrial welding robot is started again to complete the welding without secondary clamping. Example

[0029] This embodiment further illustrates the technology, wherein a fixing ring 11 is fixed to the top of the connecting rod 9.5, as shown below. Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, in this embodiment, the fixing ring 11 makes it more convenient and less strenuous for operators to rotate the connecting rod 9.5.
