Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a clamping device for welded parts. Background Technology

[0002] Automotive parts often require multiple workpieces to be welded together during processing. During the welding process, different workpieces need to be held in a fixture to assist the welding equipment in completing the welding process. However, the unloading process of existing fixtures after the workpiece welding is completed is quite complicated. It is necessary to open each clamp and remove the welded part from between the fixture and the welding equipment. The entire unloading space is relatively narrow, which increases the difficulty of unloading the finished workpiece.

[0003] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a welding part clamping device, which adjusts the material handling space between the welding equipment and the clamp according to the size of the welding part, effectively reducing the difficulty of handling the welding part.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A welding component clamping device includes a welding base with at least three legs distributed on its bottom. Lifting components are mounted on the legs, and their output ends are connected to the bottom of the welding base. At least one first chuck assembly, a second chuck assembly, and a third chuck assembly are distributed on the welding base, forming a workpiece clamping area. These chuck assemblies are used to clamp and position different workpieces.

[0007] In the aforementioned welding clamping device, the lifting component includes a lifting cylinder; the support leg is provided with a mounting groove that cooperates with and connects to the lifting cylinder, and the output end of the lifting cylinder is detachably connected to the bottom of the welding base.

[0008] In the aforementioned welding clamping device, the output end of the lifting cylinder is provided with a disassembly plate, the disassembly plate is provided with a positioning part, and the bottom of the welding base is provided with a connecting plate corresponding to the position of the disassembly plate. The connecting plate is snapped together with the positioning part.

[0009] In the welding clamping device, the connecting plate is provided with a positioning groove that cooperates with the positioning part, the positioning part is provided with a first pin hole, and the connecting plate is provided with a second pin hole that communicates with the positioning groove at the position corresponding to the first pin hole. The first pin hole and the second pin hole are connected by a connecting pin.

[0010] In the aforementioned welding component clamping device, the first pin hole is provided with an internal thread, and the end of the connecting pin near the first pin hole is provided with an external thread that connects with the internal thread.

[0011] In the welding component clamping device, the clamping heights of the first clamping assembly, the second clamping assembly, and the third clamping assembly increase sequentially.

[0012] In the aforementioned welding clamping device, the first clamp assembly, the second clamp assembly, and the third clamp assembly have identical structures. The first clamp assembly includes a lower clamp and an upper clamp. The lower clamp is connected to the welding base via a mounting seat. One end of the upper clamp is hinged to the lower clamp via a first hinge member. A push-pull cylinder is provided on one side of the lower clamp. The cylinder body of the push-pull cylinder is hinged to the lower clamp. The output end of the push-pull cylinder is hinged to the other end of the upper clamp via a second hinge member. A workpiece clamping groove is formed between the upper clamp and the lower clamp.

[0013] In the aforementioned welding clamping device, at least one flexible clamping block is provided on the side of the upper clamp and the lower clamp that is close to the workpiece clamping groove.

[0016] Beneficial effects:

[0017] This invention provides a welding component clamping device. It uses support legs to stably support a welding base and employs a lifting assembly to adjust the height of the welding base, thereby regulating the gap between the welding base and the welding equipment. During welding, the lifting assembly moves the welding base closer to the welding equipment, facilitating welding of the workpiece on the base. Conversely, when unloading the welded component, the lifting assembly lowers the welding base away from the welding equipment, increasing the space between them and making it easier for workers to remove the welded component. Furthermore, workers can adjust the material handling space according to the size of the welded component, reducing the difficulty of material handling. First, second, and third clamping assemblies are used to fix different workpieces, allowing them to be joined together for precise welding of the weld seams of each workpiece by the welding equipment.

Detailed Implementation

[0023] This utility model provides a welding component clamping device. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0024] In the description of this utility model, it should be understood that the terms "middle," "inner side," "outer side," etc., indicate the orientation or positional relationship of this utility model based on the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features.

[0025] Please see Figures 1 to 4 This utility model provides a welding component clamping device, including a welding base 1. At least three legs 2 are distributed on the bottom of the welding base 1, and a lifting component 3 is provided on each leg 2. The output end of the lifting component 3 is connected to the bottom of the welding base 1. The legs 2 support and fix the welding base 1, and the lifting height of the welding base 1 is adjusted by the lifting component 3, thereby adjusting the spatial distance between the welding base 1 and the welding equipment. When welding is required, the lifting component 3 controls the welding base 1 to rise towards the welding equipment, bringing the welding base 1 closer to the welding equipment so that the welding equipment can weld the workpiece on the welding base 1. When unloading the welded component is required, the lifting component 3 controls the welding base 1 to descend away from the welding equipment, thereby increasing the size of the welding base. The space between the welding base 1 and the welding equipment facilitates the removal of the workpiece from the welding base 1 by the operator. This allows the operator to adjust the material handling space between the welding equipment and the welding base 1 according to the size of the workpiece, effectively reducing the difficulty of handling the workpiece. At least one first chuck assembly 4, a second chuck assembly 5, and a third chuck assembly 6 are distributed on the welding base 1. The first chuck assembly 4, the second chuck assembly 5, and the third chuck assembly 6 form a workpiece clamping area. The first chuck assembly 4, the second chuck assembly 5, and the third chuck assembly 6 are used to clamp and position different workpieces. By using the first chuck assembly 4, the second chuck assembly 5, and the third chuck assembly 6 to clamp different workpieces, the workpieces can be assembled to facilitate the welding equipment to weld the weld seams of each workpiece.

[0026] like Figure 4As shown, in actual use, the first workpiece 100 is the main body of the weldment, and the second workpiece 200 and the third workpiece 300 are sub-components that need to be vertically welded onto the first workpiece 100. The first workpiece 100 is horizontally clamped and fixed onto the welding base 1 using the first clamp assembly 4. Then, the second workpiece 200 and the third workpiece 300 are vertically clamped onto the first workpiece 100 using the second clamp assembly 5 and the third clamp assembly 6, respectively. After the first workpiece 100, the second workpiece 200 and the third workpiece 300 are firmly clamped, the lifting assembly 3 is used to lift the welding base 1 towards the welding equipment, so that the first workpiece 100, the second workpiece 200 and the third workpiece 300 reach the preset welding position. After the welding process is completed, the lifting assembly 3 is used to lower the welding base 1, so that the weldment is away from the welding equipment, thereby increasing the material handling space between the welding base 1 and the welding equipment, making it easier for the operator to remove the weldment from the welding base 1.

[0027] like Figures 1 to 3 As shown, the lifting assembly 3 includes a lifting cylinder 31; the support leg 2 is provided with an installation groove that cooperates with the lifting cylinder 31, and the output end of the lifting cylinder 31 is detachably connected to the bottom of the welding base 1; by providing the lifting cylinder 31 in the support leg 2, the welding base 1 can be raised and lowered in the vertical direction of the support leg 2, thereby realizing the adjustment of the relative position between the welding base 1 and the welding equipment.

[0028] It should be noted that the lifting cylinder 31 is an existing cylinder assembly, and its specific structure and control principle are existing technologies, which will not be described in detail here.

[0029] like Figures 1 to 3 As shown, the output end of the lifting cylinder 31 is provided with a disassembly plate 32, and the disassembly plate 32 is provided with a positioning part 33. The bottom of the welding base 1 is provided with a connecting plate 11 corresponding to the position of the disassembly plate 32. The connecting plate 11 is snapped to the positioning part 33. The disassembly plate 32, the positioning part 33 and the connecting plate 11 form a detachable structure, which makes it easy for workers to disassemble and replace the welding base 1 to meet the welding requirements of different welding workpieces.

[0030] like Figures 1 to 3As shown, the connecting plate 11 is provided with a positioning groove that cooperates with the positioning part 33. The positioning part 33 is provided with a first pin hole 34. The connecting plate 11 is provided with a second pin hole 12 that communicates with the positioning groove at the position corresponding to the first pin hole 34. The first pin hole 34 and the second pin hole 12 are connected by a connecting pin 7. When disassembling the welding base 1, the connecting pin 7 is removed from the first pin hole 34 and the second pin hole 12, so that the positioning part 33 is separated from the positioning groove. At this time, the worker can remove the welding base 1 from the support leg 2. When installing the welding base 1, the connecting plate 11 at the bottom of the welding base 1 is aligned with each support leg 2. Then, the connecting plate 11 is placed on the disassembly plate 32 from top to bottom, so that the positioning part 33 is inserted into the positioning groove to complete the pre-positioning of the welding base 1. Then, the connecting pin 7 is used to lock the first pin hole 34 and the second pin hole 12 to complete the connection between the welding base 1 and the support leg 2.

[0031] like Figures 1 to 3 As shown, the first pin hole 34 is provided with an internal thread, and the end of the connecting pin 7 near the first pin hole 34 is provided with an external thread that connects with the internal thread; by providing the internal thread and the external thread, the threaded connection between the connecting pin 7 and the first pin hole 34 is realized, and the threaded connection improves the reliability of the connection between the connecting pin 7 and the first pin hole 34, and prevents the connecting pin 7 from coming out during operation.

[0032] like Figures 1 to 3 As shown, the clamping heights of the first chuck assembly 4, the second chuck assembly 5, and the third chuck assembly 6 increase sequentially; by setting the first chuck assembly 4, the second chuck assembly 5, and the third chuck assembly 6 as chuck assemblies with height differences, the clamping requirements of different workpieces can be met.

[0033] like Figures 1 to 3 As shown, the first chuck assembly 4, the second chuck assembly 5, and the third chuck assembly 6 have the same structure. The first chuck assembly 4 includes a lower chuck 41 and an upper chuck 42. The lower chuck 41 is connected to the welding base 1 via a mounting base 43. One end of the upper chuck 42 is hinged to the lower chuck 41 via a first hinge 44. The workpiece is clamped using the openable upper chuck 42 and lower chuck 41. A push-pull cylinder 45 is provided on one side of the lower chuck 41. The cylinder body of the push-pull cylinder 45 is hinged to the lower chuck 41, and the output end of the push-pull cylinder 45 is hinged to the other end of the upper chuck 42 via a second hinge 46. A workpiece clamping groove is formed between the upper chuck 42 and the lower chuck 41. In use, the push-pull cylinder 45 is used to push and pull one end of the upper chuck 42, so that the upper chuck 42 can open and close relative to the lower chuck 41, thereby realizing the opening and closing action of the workpiece clamping groove.

[0034] In this embodiment, the first hinge member 44 is a hinge plate, which is disposed on both sides of the upper clamp, and the free end of the hinge plate is hinged to the lower clamp.

[0035] In this embodiment, the second hinge member 46 is a connecting rod, and each end of the connecting rod is provided with a hinge seat. The two hinge seats are respectively hinged to one end of the upper clamp 42 and the output end of the push-pull cylinder 45.

[0036] It should be noted that the push-pull cylinder 45 is an existing cylinder assembly, and its specific structure and control principle are existing technologies, which will not be described in detail here.

[0037] like Figures 1 to 3 As shown, at least one flexible clamping block 47 is provided on the side of the upper chuck 42 and the lower chuck 41 near the workpiece clamping groove; by providing the flexible clamping block 47, damage to the workpiece is avoided by the upper chuck 42 and the lower chuck 41 when clamping the workpiece, and the safety of the workpiece is improved when clamping.

[0038] In one embodiment, the flexible clamping block 47 can be a clamping block with flexible properties, such as a silicone clamping block, a rubber clamping block, or a plastic clamping block.

[0039] like Figures 1 to 3 As shown, the first chuck assembly 4 also includes a vertically movable top support 48, which is disposed on one side of the lower chuck 41. The top support 48 is used to position the workpiece to achieve pre-positioning of the workpiece. When the workpiece is placed on the chuck assembly, the top support 48 is used to support and position the top of the workpiece, so that the chuck assembly can be more stable when clamping the workpiece and will not have the problem of displacement.

[0040] like Figures 1 to 3 As shown, the top support 48 includes a top support cylinder 49, the cylinder body of which is connected to the lower clamp 41, and an ejector pin 410 is provided on the output end of the top support cylinder 49. In use, the top support cylinder 49 drives the ejector pin 410 to move up and down at the bottom of the workpiece. When it is necessary to pre-position the workpiece, the top support cylinder 49 drives the ejector pin 410 to move towards the bottom of the workpiece until it supports the bottom of the workpiece, thereby completing the pre-positioning of the workpiece.

[0041] It should be noted that the top support cylinder 49 is an existing cylinder assembly, and its specific structure and control principle are existing technologies, which will not be described in detail here.

[0042] In summary, the welding base 1 is stably supported by the support legs 2, and the height of the welding base 1 is adjusted using the lifting assembly 3, thereby adjusting the gap between the welding base 1 and the welding equipment. When welding a workpiece, the lifting assembly 3 moves the welding base 1 towards the welding equipment, bringing it closer to the equipment and facilitating welding of the workpiece on the base. Conversely, when unloading the welded part, the lifting assembly 3 lowers the welding base 1 away from the welding equipment, increasing the space between them and making it easier for workers to remove the welded part. Furthermore, workers can adjust the material handling space according to the size of the welded part, reducing the difficulty of material handling. The first, second, and third clamping assemblies 6 are used to fix different workpieces, allowing them to be joined together so that the welding equipment can accurately weld the welds of each workpiece.
