Description

Technical Field

[0001] This invention relates to the field of welding positioning fixture technology, and in particular to a welding positioning fixture for hardware parts that can be adjusted at multiple angles. Background Technology

[0002] Hardware accessories refer to machine parts or components made of hardware, as well as some small hardware products. They can be used alone or as auxiliary tools, such as hardware tools, hardware parts, daily hardware, building hardware, and security products. Tooling refers to the general term for tools used in the manufacturing process, i.e., process equipment. In the machining process, through the cooperation of machining equipment, tooling, and raw materials, various mechanical parts are finally produced. Among them, a welding positioning tooling is needed in the welding of hardware parts.

[0003] A search revealed Chinese invention patent CN117381300A, which discloses a welding and processing equipment for security hardware parts. The equipment includes: a support platform; a support assembly symmetrically disposed on the outside of the support platform; a fixing mechanism; and a processing mechanism disposed on the outside of the fixing mechanism. The fixing mechanism includes: a placement assembly slidably connected to the support platform; a positioning assembly symmetrically disposed on both sides of the placement assembly; a clamping assembly surrounding and connected to the placement assembly; and a control assembly connected to both the support platform and the placement assembly. By using the fixing mechanism, the processed hardware parts are clamped and fixed in four directions. The clamping structure is simple and easy to manufacture, effectively reducing the manufacturing cost of tooling. It can also lift the product for easy removal.

[0004] Existing tooling uses fixed positioning columns or templates, which can only accommodate parts of a single size. Changing product models requires stopping the machine to reassemble the fixture, which seriously affects production efficiency. Traditional tooling relies on manually stacking pads to adjust the height, which is time-consuming and difficult to control the accuracy. It is particularly inefficient in multi-layer welding or variable cross-section parts processing. Most tooling is rigidly fixed and cannot meet the needs of scenarios such as curved welds and mitered joints that require multi-angle adjustment. Forced displacement may lead to positioning failure. In addition, traditional mechanical clamping lacks elastic compensation and cannot absorb the small displacement caused by part tolerances or thermal deformation, which can easily lead to loosening after long-term use.

[0005] Therefore, the existing multi-angle adjustable welding and positioning fixture for hardware parts cannot meet the needs of actual use, so there is an urgent need for improved technology in the market to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a welding positioning fixture for hardware parts that can be adjusted at multiple angles, thereby solving the problems mentioned in the background art.

[0010] Preferably, the longitudinal clamping structure includes longitudinal sliders symmetrically slidably connected to the inner cavity of the transverse longitudinal moving frame, a rotating rod passing through the longitudinal slider and threadedly connected, a connecting column fixedly connected to the lower end face of the longitudinal slider, a transverse mounting block fixedly connected to the lower end face of the connecting column, an extrusion turntable rotatably connected to one adjacent end of each of the two transverse mounting blocks, and an anti-slip pad fixedly connected to one adjacent side of each of the two extrusion turntables. The anti-slip pad is specifically an arc-shaped structure, and limit holes are evenly opened around the center point on the side of the extrusion turntable near the transverse mounting block.

[0011] Preferably, the limiting structure includes a telescopic frame fixedly connected to the middle of the lower end face of the transverse mounting block, a limiting spring fixedly connected to the inner wall of the telescopic frame, a limiting post slidably connected to the inner cavity of the telescopic frame, and a limiting spring drivingly connected between the telescopic frame and the limiting post. The end of the limiting post away from the limiting spring matches the inner cavity of the limiting hole on the extrusion turntable.

[0012] Preferably, the transverse extrusion structure includes a transverse slide rod fixedly connected to the inner cavity of the transverse moving frame, and extrusion sliders are slidably connected to the inner cavities of the two transverse moving frames respectively. The transverse slide rod passes through the extrusion slider and is slidably connected. An extrusion spring is transmittedly connected between the inner cavity of the transverse moving frame and the extrusion slider on the side of the transverse moving frame close to the transverse longitudinal moving frame. The extrusion spring is movably sleeved on the outer surface of the transverse slide rod. A transverse clamping structure is fixedly connected to the lower end face of the extrusion slider.

[0013] Preferably, the transverse clamping structure includes a second connecting column fixedly connected to the lower end face of the extrusion slider, a transverse connecting block fixedly connected to the lower end face of the second connecting column, and a transverse positioning column fixedly connected to one adjacent end of each of the two transverse connecting blocks, and a groove for fixing the part is provided in the middle of the side of the transverse positioning column away from the transverse connecting block.

[0014] Preferably, the lateral adjustment structure includes a rotating frame fixedly connected to the upper end face of the extrusion slider, one end of a connecting rod is rotatably connected to the inner cavity of the rotating frame, the other end of the connecting rod is rotatably connected to a connecting rod, and the connecting rod is located between the two connecting rods.

[0015] Preferably, the lifting structure includes an electric telescopic rod symmetrically fixedly connected to the middle of the upper surface of the base plate along the center line, a lifting plate fixedly connected to the upper surface of the electric telescopic rod, anti-slip protrusions evenly fixedly connected to the upper surface of the lifting plate, and an electric control module fixedly connected to the upper surface of the base plate between the electric telescopic rods. The inner cavity of the electric control module is specifically provided with a power supply, a power switch, a voltage controller, and a timer for the duration of power-on of the control circuit.

[0016] The present invention has the following beneficial effects: This invention utilizes an installation structure mounted on a base plate to mount and place a longitudinal drive structure, a longitudinal clamping structure, and a transverse extrusion structure during use. The longitudinal and transverse movement of the transverse and longitudinal moving frames achieves center positioning and clamping of the part. The longitudinal drive structure on the installation structure employs a power transmission chain of motor → pulley → rotating rod → longitudinal slider, combined with the linear feed of the extrusion turntable, forming a clamping system with high repeatability. Furthermore, the dual protection of belt drive backlash elimination design and limiting structure eliminates micro-displacement caused by vibration, meeting the welding process's requirement for zero-millimeter precision. The longitudinal clamping structure is used to install and place the limiting structure during use. Simultaneously, the longitudinal slider and the extrusion turntable move in opposite directions to achieve longitudinal clamping of the parts. Then, during welding, the extrusion turntable can adjust the parts at multiple angles. The limiting structure on the longitudinal clamping structure enables stepless angle adjustment during use. After rotation to the correct position, the limiting spring drives the limiting post to reset and engage with the limiting hole of the turntable, forming a mechanical limit to ensure precise fixation of the rotation angle and meet the needs of multi-angle welding. Furthermore, the rigid engagement between the limiting post and the limiting hole of the turntable effectively prevents the extrusion turntable from rotating unexpectedly due to vibration or external force during clamping, thus improving the stability of the welding process.

[0017] This invention utilizes a transverse extrusion structure mounted on the installation structure. During use, the continuous tension of the compression spring and the rigid limiting structure work together to effectively counteract thermal deformation stress or external force interference during welding, maintaining stable part positioning and ensuring consistent welding quality. Furthermore, the linkage mechanism formed by the compression spring and the compression slider, in conjunction with the opening and closing action of the rotating frame, allows for dynamic adjustment of the transverse positioning post spacing. This design supports both a wide range of initial positioning spacing increases for easier workpiece handling and a precise clamping spacing reduction through spring self-locking, enhancing stability. The continuous tension of the compression spring and the rigid limiting structure work together to effectively counteract thermal deformation stress or external force interference during welding, maintaining stable part positioning and ensuring consistent welding quality. The transverse clamping structure on the transverse extrusion structure provides transverse clamping and fixation of the parts during use, facilitating precise welding of connected parts. Finally, the outward movement of the compression slider extends the compression spring, adjusting the transverse positioning post spacing. Flexible expansion allows the lateral clamping structure to adapt to parts of different widths. The lateral adjustment mechanism on the lateral clamping structure allows for adjustment of the distance between the two lateral clamping structures by pressing the connecting rods during use. The interaction between the lateral adjustment structure and the lateral extrusion structure enables rapid lateral clamping and ensures stable positioning of the part in the X-axis direction. The ergonomic design of the lateral adjustment structure's press-type operation reduces operator fatigue. The electric lifting process is precisely controlled, avoiding the risk of injury from manual adjustments. The lifting structure on the base plate, linked to the electric telescopic rod via the electric control module, automates the adjustment of part height, reducing manual handling and adjustment time and improving operational efficiency. The lifting process is smooth and controllable, preventing damage to parts from impacts. Furthermore, the wide-range design of the adjustable lateral positioning column spacing, lifting plate stroke, and extrusion turntable clamping range allows for adaptation to various sizes and shapes of hardware parts, enhancing the versatility of the tooling.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0023] Please see Figure 1-7 As shown, this embodiment is a multi-angle adjustable welding positioning fixture for hardware parts, including a base plate 1, an installation structure 2 fixedly connected to the upper end face of the base plate 1, a longitudinal driving structure 3 provided in the middle of the inner cavity of the installation structure 2, a longitudinal clamping structure 4 symmetrically arranged laterally in the inner cavity of the installation structure 2, a limit structure 5 provided in the middle of the lower end face of the longitudinal clamping structure 4, a transverse extrusion structure 6 symmetrically arranged longitudinally in the inner cavity of the installation structure 2, a transverse clamping structure 7 fixedly connected to the lower end face of the transverse extrusion structure 6, a transverse adjustment structure 8 provided on the upper end face of the transverse extrusion structure 6, and a lifting structure 9 fixedly connected to the middle of the upper end face of the base plate 1.

[0024] Furthermore, the mounting structure 2 includes mounting posts 21 fixedly connected to the four corners of the upper surface of the base plate 1. A mounting frame 22 is fixedly connected to the upper surface of the mounting posts 21. A transverse longitudinal moving frame 23 is fixedly connected to the middle of the inner cavity of the mounting frame 22 along the longitudinal center line. A transverse moving frame 24 is symmetrically fixedly connected to the middle of the inner cavity of the mounting frame 22 with the transverse longitudinal moving frame 23 as the center line. A longitudinal driving structure 3 and a longitudinal clamping structure 4 are provided in the inner cavity of the transverse moving frame 23. A transverse pressing structure 6 is slidably connected to the inner cavity of the transverse moving frame 24. Through the mounting structure 2 on the base plate 1, the longitudinal driving structure 3, the longitudinal clamping structure 4 and the transverse pressing structure 6 are installed and placed during use. Then, through the longitudinal and transverse movement of the transverse longitudinal moving frame 23 and the transverse moving frame 24, the center positioning and clamping of the part is achieved.

[0025] Furthermore, the longitudinal drive structure 3 includes a rotating rod 31 rotatably connected to the inner cavity of the transverse longitudinal moving frame 23. A pulley 32 is rotatably connected to the middle of the front end face of the mounting frame 22. The rotating shaft of the front end face of the rotating rod 31 passes through the mounting frame 22 and is fixedly connected to the pulley 32. A drive motor 34 is fixedly connected to the front end of the upper end of the mounting frame 22. Another pulley 32 is fixedly connected to the output end of the drive motor 34. A belt 33 is connected between the two pulleys 32. A longitudinal clamping structure 4 is symmetrically threaded on the outer surface of the rotating rod 31. Two sections of threads with opposite directions are symmetrically opened on the outer surface of the rotating rod 31. Through the longitudinal drive structure 3 on the mounting structure 2, the power transmission chain of motor 34 → pulley 32 / 33 → rotating rod 31 → longitudinal slider 41 is adopted in use. With the linear feed of the extrusion turntable 44, a clamping system with high repeatability positioning accuracy is formed. Furthermore, through the double protection of belt drive backlash elimination design and limit structure 5, micro-displacement caused by vibration is eliminated, meeting the welding process requirements for zero-millimeter accuracy.

[0026] Furthermore, the longitudinal clamping structure 4 includes a longitudinal slider 41 symmetrically slidably connected to the inner cavity of the transverse longitudinal moving frame 23. A rotating rod 31 passes through the longitudinal slider 41 and is threadedly connected. A connecting post 42 is fixedly connected to the lower end face of the longitudinal slider 41. A transverse mounting block 43 is fixedly connected to the lower end face of the connecting post 42. An extrusion turntable 44 is rotatably connected to one adjacent end of each of the two transverse mounting blocks 43. An anti-slip pad is fixedly connected to one adjacent side of each of the two extrusion turntables 44. The anti-slip pad is specifically an arc-shaped structure. Limiting holes are evenly opened around the center point on the side of the extrusion turntable 44 near the transverse mounting block 43. Through the longitudinal clamping structure 4 on the mounting structure 2, the limiting structure 5 is installed and placed during use. At the same time, the longitudinal clamping of the parts is achieved by the relative movement of the longitudinal slider 41 and the extrusion turntable 44. Thus, the parts can be adjusted at multiple angles during welding operations through the extrusion turntable 44.

[0027] Furthermore, the limiting structure 5 includes a telescopic frame 51 fixedly connected to the middle of the lower end face of the transverse mounting block 43. A limiting spring 52 is fixedly connected to the inner wall of the telescopic frame 51, and a limiting post 53 is slidably connected to the inner cavity of the telescopic frame 51. The limiting spring 52 is driven between the telescopic frame 51 and the limiting post 53. The end of the limiting post 53 away from the limiting spring 52 matches the inner cavity of the limiting hole on the extrusion turntable 44. Through the limiting structure 5 on the longitudinal clamping structure 4, stepless angle adjustment can be achieved during use. After rotation to the correct position, the limiting spring 52 drives the limiting post 53 to reset and engage with the limiting hole of the turntable, forming a mechanical limit to ensure that the rotation angle is accurately fixed and to meet the requirements of multi-angle welding. Furthermore, through the rigid engagement of the limiting post 53 with the limiting hole of the turntable, the extrusion turntable 44 is effectively prevented from rotating unexpectedly due to vibration or external force during clamping, thus improving the stability of the welding process.

[0028] Furthermore, the transverse extrusion structure 6 includes a transverse slide rod 61 fixedly connected to the inner cavity of the transverse moving frame 24. Extrusion sliders 63 are slidably connected to the inner cavities of the two transverse moving frames 24 respectively. The transverse slide rod 61 passes through and is slidably connected to the extrusion sliders 63. A compression spring 62 is connected between the inner cavity of the transverse moving frame 24 near the transverse longitudinal moving frame 23 and the extrusion slider 63. The compression spring 62 is movably sleeved on the outer surface of the transverse slide rod 61. A transverse clamping structure 7 is fixedly connected to the lower end face of the extrusion slider 63. Through the transverse extrusion structure 6 on the mounting structure 2, during use, the continuous tension of the compression spring 62 and the rigid limiting of the limiting structure 5 work together to... This design effectively counteracts thermal deformation stress or external force interference during the welding process, maintains stable part positioning, and ensures consistent welding quality. Furthermore, through the linkage mechanism formed by the compression spring 62 and the compression slider 63, and in conjunction with the opening and closing action of the rotating frame 81, the spacing between the transverse positioning columns 73 can be dynamically adjusted. This design not only supports a large range of initial positioning spacing increases to facilitate workpiece placement and removal, but also achieves precise clamping spacing reduction through spring self-locking to enhance stability. The continuous tension of the compression spring 62 and the rigid limit of the limiting structure 5 work together to effectively counteract thermal deformation stress or external force interference during the welding process, maintain stable part positioning, and ensure consistent welding quality.

[0029] Furthermore, the transverse clamping structure 7 includes a connecting post 71 fixedly connected to the lower end face of the extrusion slider 63. A transverse connecting block 72 is fixedly connected to the lower end face of the connecting post 71. A transverse positioning post 73 is fixedly connected to one adjacent end of each of the two transverse connecting blocks 72. A groove for fixing the part is opened in the middle of the side of the transverse positioning post 73 away from the transverse connecting block 72. Through the transverse clamping structure 7 on the transverse extrusion structure 6, the part is transversely clamped and fixed in use, which makes it convenient for personnel to accurately weld the connected parts. Then, by moving the extrusion slider 63 outward, the extrusion spring 62 is extended, and the spacing of the transverse positioning posts 73 is flexibly expanded, so that the transverse clamping structure 7 can adapt to parts of different widths.

[0030] Furthermore, the lateral adjustment structure 8 includes a rotating frame 81 fixedly connected to the upper end face of the extrusion slider 63. One end of a connecting rod 82 is rotatably connected to the inner cavity of the rotating frame 81, and the other end of the connecting rod 82 is rotatably connected to a connecting rod 83. The connecting rod 83 is located between the two connecting rods 82. Through the lateral adjustment structure 8 on the lateral clamping structure 7, the distance between the two lateral clamping structures 7 can be adjusted and controlled by pressing the connecting rod 83 during use. Thus, rapid lateral clamping is achieved through the interaction between the lateral adjustment structure 8 and the lateral extrusion structure 6, and the parts are stably positioned in the X-axis direction. At the same time, the pressing operation design of the lateral adjustment structure 8 is ergonomic and reduces operator fatigue. The electric lifting process can be precisely controlled, avoiding the risk of pinching that may be caused by manual adjustment.

[0031] Furthermore, the lifting structure 9 includes an electric telescopic rod 91 symmetrically fixedly connected to the center of the upper surface of the base plate 1 along the center line. A lifting plate 92 is fixedly connected to the upper surface of the electric telescopic rod 91. Anti-slip protrusions are uniformly fixedly connected to the upper surface of the lifting plate 92. An electric control module 93 is fixedly connected to the upper surface of the base plate 1 between the electric telescopic rods 91. The inner cavity of the electric control module 93 is specifically equipped with a power supply, a power switch, a voltage controller, and a timer for the duration of power-on of the control circuit. Through the lifting structure 9 on the base plate 1, the electric control module 93 and the electric telescopic rod 91 are linked during use to realize the automatic adjustment of the height of the parts, reduce the time for manual handling and adjustment, and improve the operating efficiency. The lifting process is stable and controllable, avoiding damage to the parts from collisions. Furthermore, since the adjustable range of the spacing of the transverse positioning column 73, the lifting stroke of the lifting plate 92, and the clamping range of the extrusion turntable 44 are all designed with a wide range, they can be adapted to hardware parts of various sizes and shapes, improving the versatility of the tooling.

[0032] Working principle: During operation, pressing the horizontal adjustment structure 8 causes the connecting rod 2 83 to move downward, so the connecting rod 1 82 rotates relative to each other. As a result, the rotating frame 81 moves away from each other, which in turn drives the extrusion slider 63 to move away from each other. Therefore, the extrusion spring 62 extends, and at the same time, the distance between the horizontal positioning columns 73 increases. At this time, the part is placed on the upper surface of the lifting plate 92. The electric control module 93 is then activated, and the electric telescopic rod 91 is extended under the control of the electric control module 93. As a result, the height of the lifting plate 92 and the part rises, so the part is located between the two extrusion turntables 44. At this time, the longitudinal drive structure 3 is activated, causing the output end of the drive motor 34 to rotate. This causes the pulley 32 to rotate, which in turn causes the belt 33 to rotate. The belt 33 then causes the other pulley 32 to rotate, further causing the rotating rod 31 to rotate. The rotation of the rotating rod 31 causes the longitudinal sliders 41 to move closer together. Since the extrusion turntable 44 is connected to the longitudinal sliders 41 via the transverse mounting block 43 and connecting post 42, the extrusion turntables 44 move closer together, longitudinally clamping the parts. At this time, because the transverse mounting block 43 is equipped with a limit structure 5, the extrusion turntable 44 is limited by the engagement of the limit post 53, preventing free rotation of the extrusion turntable 44. At the same time, the personnel release the connecting rod 83. At this time, the compression spring 62 contracts, so the compression sliders 63 move closer to each other, thereby causing the connecting rod 82 to rotate in the opposite direction. As a result, the spacing between the transverse positioning posts 73 is reduced, thereby laterally positioning and clamping the part. When the part needs to be rotated at an angle, press the lateral adjustment structure 8 to make the lateral positioning posts 73 move away from each other. At this time, push one side of the part so that the two extrusion turntables 44 rotate due to friction. When the extrusion turntable 44 rotates, the limiting post 53 retracts into the inner cavity of the telescopic frame 51, thus realizing the multi-angle rotation of the extrusion turntable 44 and the part. When the rotation is completed, the limiting spring 52 extends, so the limiting post 53 slides outward and engages with the limiting hole on the extrusion turntable 44, thereby fixing and limiting the rotated extrusion turntable 44.
