Currently, welding positioning equipment often employs a single fixture or fixed-station design, necessitating the customization of dedicated positioning modules for specific parts. During product changeovers, the fixture positions need to be readjusted, which extends the welding cycle to some extent. Furthermore, existing welding positioning devices typically use linearly arranged or single-ring distributed fixture layouts, which not only occupy significant space but also hinder the achievement of a compact production process.
[0003] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

Detailed Implementation
[0023] This utility model provides a welding positioning device and a welding 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 positioning device, including a base 1, a base plate 2 on the top of the base 1, a horizontal rotating part 3 on the base plate 2, and a turntable 4 on the top surface of the base plate 2. The turntable 4 is rotatably connected to the horizontal rotating part 3. The horizontal rotating part 3 drives the turntable 4 to rotate in a horizontal plane. The horizontal rotating part 3 on the base plate 2 serves as a power source, driving the turntable 4 on the top surface of the base plate 2 to rotate precisely in a horizontal plane, thereby enabling the turntable 4 to switch between different work positions.
[0026] Specifically, multiple first clamping assemblies 5 are arranged in a ring on the turntable 4, and multiple second clamping assemblies 6 are arranged in a ring around the first clamping assemblies 5 on the turntable 4. Adjacent first clamping assemblies 5 and second clamping assemblies 6 are staggered. The staggered design of the first clamping assemblies 5 and second clamping assemblies 6 arranged in a ring on the turntable 4 avoids motion interference. Each set of clamps can be customized with positioning pins, clamping cylinders and other components according to the characteristics of the parts. The double-layer staggered design avoids the problem of mutual interference between clamping assemblies during movement. Combined with the compact path of horizontal rotation, the processes of feeding, welding and unloading can be completed in the same turntable 4 without the need for multiple equipment in series, reducing site occupation costs.
[0027] like Figures 1 to 4 As shown, furthermore, vertical rotating parts 7 are respectively provided on both sides of the top of the base 1, and rotating arms 8 are respectively provided on the bottom of both sides of the substrate 2. The two rotating arms 8 are rotatably connected to the vertical rotating parts 7 on the sides. The vertical rotating parts 7 on both sides of the top of the base 1 serve as the power source for vertical rotation and are connected to the rotating arms 8 on the bottom of both sides of the substrate 2 through bearings. When the vertical rotating parts 7 are activated, the rotating arms 8 on both sides can synchronously drive the substrate 2 to rotate around the vertical axis, thereby realizing the tilting or flipping of the entire turntable 4 and the double-ring clamp, and cooperating with the horizontal rotating part 3 to realize the two-axis movement of this device.
[0028] It should be noted that the vertical rotating part 7 is an existing motor rotation assembly, such as a rotation assembly composed of a servo motor, a harmonic reducer and an angle sensor. In addition, it will also be equipped with a corresponding controller, such as a PLC controller or a microprocessor controller. The specific structure and working principle are existing technologies and will not be described in detail here.
[0029] like Figures 1 to 4 As shown, the horizontal rotating part 3 further includes a rotating platform 31 and a rotating shaft 32. The rotating platform 31 is disposed at the bottom of the turntable 4. A shaft hole 41 is provided on the turntable 4 at a position corresponding to the output end of the rotating platform 31. The shaft hole 41 is connected to the output end of the rotating platform 31 through the rotating shaft 32. The rotating platform 31 serves as a power output source and is rigidly connected to the turntable 4 through the rotating shaft 32. The shaft hole 41 at the corresponding position on the bottom of the turntable 4 is connected to the rotating shaft 32 by a key or an interference fit to ensure clearance-free power transmission. When the rotating platform 31 is started, the torque of the servo motor in the rotating platform 31 is amplified by a reducer and directly drives the turntable 4 to rotate through the rotating shaft 32, realizing the fixed-angle rotation of the turntable 4.
[0030] It should be noted that the rotary platform 31 is an existing rotary platform composed of an integrated servo motor, a precision reducer and a position feedback device. The specific structure and working principle are existing technologies and will not be described in detail here.
[0031] like Figures 1 to 4 As shown, further, the turntable 4 is provided with a first mounting groove 42 corresponding to the bottom of each of the first clamping components 5, and the bottom of the first clamping component 5 is provided with a first connecting post 51 that mates with the first mounting groove 42; the turntable 4 is provided with a first mounting groove 42 corresponding to the position of each of the first clamping components 5, and the bottom of the first clamping component 5 is integrally formed or fixedly connected to the first connecting post 51, which is adapted to the first mounting groove 42. During installation, the first connecting post 51 slides into the groove along the guide of the mounting groove 53, and the initial positioning is achieved by the tight fit between the outer wall of the first connecting post 51 and the reference surface of the first mounting groove 42. Then, the first clamping component 5 is fixed by the connector.
[0032] like Figures 1 to 4 As shown, the first connecting post 51 is further provided with a first external thread. After passing through the first mounting groove 42, the first connecting post 51 is threadedly connected to the first connecting nut 44. The outer wall of the first connecting post 51 is provided with the first external thread, the length of which is greater than the depth of the first mounting groove 42. After the first connecting post 51 passes through the first mounting groove 42, the first connecting nut 44 is screwed into the first connecting post 51 from below the turntable 4. The tight fit between the first connecting nut 44 and the bottom surface of the turntable 4 generates an axial preload, pressing the first connecting post 51 tightly into the first mounting groove 42. In addition, to prevent loosening, an anti-loosening washer can be installed between the first connecting nut 44 and the turntable 4. The elastic deformation of the washer counteracts the tendency of the threads to loosen due to welding vibration.
[0033] like Figures 1 to 4 As shown, further, the turntable 4 is provided with a second mounting groove 43 corresponding to the bottom of each of the second clamping components 6, and the bottom of the second clamping component 6 is provided with a second connecting post 61 that mates with the second mounting groove 43; the turntable 4 is provided with a second mounting groove 43 corresponding to the position of each of the second clamping components 6, and the bottom of the second clamping component 6 is integrally formed or fixedly connected to the second connecting post 61, which is adapted to the second mounting groove 43. During installation, the second connecting post 61 slides into the groove along the guide of the mounting groove 53, and the initial positioning is achieved by the tight fit between the outer wall of the second connecting post 61 and the reference surface of the second mounting groove 43. Then, the second clamping component 6 is fixed by the connector.
[0034] like Figures 1 to 4As shown, the second connecting post 61 is further provided with a second external thread, and after passing through the second mounting groove 43, the second connecting post 61 is threadedly connected to the second connecting nut 45. The outer wall of the first connecting post 51 is provided with a first external thread, the length of which is greater than the depth of the first mounting groove 42. After the second connecting post 61 passes through the second mounting groove 43, the second connecting nut 45 is screwed into the second connecting post 61 from below the turntable 4. The tight fit between the second connecting nut 45 and the bottom surface of the turntable 4 generates an axial preload, pressing the second connecting post 61 tightly into the second mounting groove 43. In addition, to prevent loosening, an anti-loosening washer can be installed between the second connecting nut 45 and the turntable 4. The elastic deformation of the washer counteracts the tendency of the threads to loosen due to welding vibration.
[0035] like Figures 1 to 4 As shown, the first clamping assembly 5 and the second clamping assembly 6 have identical structures. The first clamping assembly 5 includes a mold base 52, on which an assembly groove 53 is provided along its length. At least one workpiece clamp 54 is disposed within the assembly groove 53. Although automotive parts are diverse, similar parts often differ only in size. Traditional clamps require custom-made mold bases 52 for each size, resulting in long design cycles and high manufacturing costs. The assembly groove 53 on the mold base 52 allows the workpiece clamp 54 to be adjusted along its length, or the workpiece fixture can be changed according to different sizes of welded workpieces. The size changes of similar parts can be adapted by sliding positioning. For example, for a gearbox bracket with a length of 350-500mm, there is no need to change the mold base 52; positioning can be completed simply by adjusting the position of the workpiece clamp 54.
[0036] like Figures 1 to 4 As shown, furthermore, support pads 11 are provided at the four corners of the bottom of the base 1; by providing support pads at the bottom of the base 1, the overall stability of the base 1 can be improved, and the problem of displacement of the base 1 during operation can be avoided.
[0037] This utility model also provides a welding device, including the welding positioning device as described above.
[0038] In summary, among the clamping assemblies arranged in a ring on the turntable 4, the first clamping assembly 5 and the second clamping assembly 6 employ a staggered design to avoid motion interference. Each set of clamps can be customized according to the characteristics of the parts, including key components such as locating pins and clamping cylinders. The inner and outer double-layer staggered design effectively avoids mutual interference between clamping assemblies during movement. Combined with the compact path of horizontal rotation, processes such as loading, welding, and unloading are efficiently completed within the same turntable 4, eliminating the need for multiple devices connected in series, thus significantly reducing the cost of occupancy in the production space.
