Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a tooling fixture for manufacturing hardware parts. Background Technology

[0002] Machining refers to the process of altering the shape, size, or properties of a workpiece using mechanical equipment. This includes workpiece machining design, preparation, CNC programming, equipment debugging, and machining operations. During machining, appropriate cutting processes, such as milling and drilling, are selected based on the workpiece requirements. Simultaneously, cutting fluid is used for cooling and lubrication to ensure machining quality and efficiency. Finally, the machined workpiece is inspected and its quality controlled to ensure machining accuracy and quality. Fixing the workpiece during machining is crucial for ensuring machining accuracy and quality. It not only limits workpiece displacement and vibration but also ensures machining consistency. For mass-produced hardware parts, a uniform and stable fixing method ensures that each workpiece has the same position and stress state during machining. Clamping workpieces requires manual adjustment of the workpiece's state and clamping angle, which significantly increases the labor intensity of workers and reduces welding efficiency.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent application number 202421250822.0, application date 2024-06-03) provides an automated welding fixture for automobile manufacturing, comprising: a base frame; and two mounting plates, which are symmetrically distributed and fixedly installed between the two sides of the inner wall of the base frame. Two sliding plates are symmetrically distributed and slidably installed on the top of the mounting plates. A moving component drives the sliding plates to move, thereby simultaneously bringing the two rows of clamping plates closer together to clamp and fix the workpiece placed in the middle, thus achieving automated clamping. After welding one side of the workpiece, a drive motor drives a mechanical claw to grasp the workpiece, and then the drive motor rotates the clamped workpiece, turning the angle to flip out the lower part, clamping it again, and welding it. This achieves automated welding of multiple surfaces, avoiding manual adjustment by workers, greatly reducing the labor intensity of workers, improving the efficiency of workpiece welding, and facilitating use.

[0004] When clamping a workpiece, it is impossible to ensure that the force is applied evenly to the workpiece, resulting in the clamping force on one side of the workpiece being much greater than that on the other side. This causes the workpiece to bear large local stress, forming a stress concentration source. During use, the above-mentioned device cannot avoid the stress concentration generated during clamping, resulting in the machined dimensions not matching the design dimensions, affecting the fit accuracy between the workpiece and other components, and making the cutting process unstable, resulting in unevenness on the machined surface and increasing surface roughness. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tooling fixture for manufacturing hardware parts, comprising a frame, a worktable fixedly connected to the upper surface of the frame, a fixed plate fixedly connected to the upper surface of the worktable, a limit rod fixedly connected to the surface of the fixed plate, and a clamping plate slidably connected to the limit rod; a baffle fixedly connected to the upper rear side of the frame, the baffles being symmetrically distributed about the center of the frame, and a movable column fixedly connected to the upper surface of the baffle, with a force-bearing plate slidably connected to the movable column; a motor fixedly connected to the upper surface of the frame, the upper surface of the motor fitting against the lower surface of the worktable, and a rotating shaft fixedly connected to the output end of the motor, the rotating shaft being rotatably disposed inside the frame; a push block fixedly connected to the lower surface of the force-bearing plate, the upper surface of the push block being arc-shaped.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1: The stability of the device is improved by setting the fixed plate 3, the worktable 2, and the baffle 19 to prevent shaking during operation. Figures 1-2 As shown: It includes a frame 1, a worktable 2 is fixedly connected to the upper surface of the frame 1, and a fixed plate 3 is fixedly connected to the upper surface of the worktable 2. A limit rod 4 is fixedly connected to the surface of the fixed plate 3, and a clamping plate 5 is slidably connected through the limit rod 4. A baffle 19 is fixedly connected to the upper rear side of the frame 1, and the baffle 19 is symmetrically distributed about the center of the frame 1. A moving column 20 is fixedly connected to the upper surface of the baffle 19, and a force-bearing plate 21 is slidably connected through the moving column 20. A motor 6 is fixedly connected to the upper surface of the frame 1, and the upper surface of the motor 6 is in contact with the lower surface of the worktable 2. A rotating shaft 7 is fixedly connected to the output end of the motor 6, and the rotating shaft 7 is rotatably set inside the frame 1. A push block 18 is fixedly connected to the lower surface of the force-bearing plate 21, and the upper surface of the push block 18 is arc-shaped.

[0029] The operator places the workpiece to be processed on the upper surface of the workbench 2, ensuring that the workpiece and the clamping plate 5 are parallel and that the clamping plate 5 can stably clamp the workpiece. The operator controls the motor 6, causing the rotating shaft 7 to rotate inside the frame 1. As the rotating shaft 7 operates, it drives the clamping plate 5 to slide on the surface of the limiting rod 4, thereby fixing the workpiece to be processed. The fixed column 16 and the connecting block 13 improve the stability of the device, reduce the friction between the support rod 12 and the workbench 2, extend the service life of the support rod 12, and ensure that the clamping plate 5 can operate stably.

[0030] In Example 2, unlike Example 1, the fixed block 8, connecting rod 11, and sliding rod 14 ensure that the clamping force is applied evenly to the workpiece, thus improving the processing accuracy of the device. Figures 3-5 As shown: A fixing rod 9 is fixedly connected to one end of the lower surface of the frame 1 near the rotating shaft 7, and a fixing block 8 is slidably connected to the fixing rod 9. The fixing block 8 is threadedly connected to the surface of the rotating shaft 7, and a base 10 is movably connected to the end of the rotating shaft 7. The base 10 is fixedly connected to the inner wall of the frame 1. A connecting block 13 is fixedly connected to the upper outer side of the frame 1. One end of a connecting rod 11 is movably connected to the outer side of the clamping plate 5, and a support rod 12 is movably connected to the other end of the connecting rod 11. The support rod 12 is rotatably disposed inside the connecting block 13. A sliding rod 14 is fixedly connected to the surface of the support rod 12, and a moving rod 15 is movably connected to the surface of the sliding rod 14. The other end of the moving rod 15 is movably connected to the fixing block 8. The sliding rods 14 are symmetrically distributed about the center of the fixing block 8, and a fixing column 16 is movably connected to the end of the sliding rod 14. One end of a sliding column 17 is slidably connected to the inner wall of the fixing column 16, and the other end of the sliding column 17 is movably connected to the sliding rod 14.

[0031] As the rotating shaft 7 rotates inside the frame 1, it drives the fixed block 8 connected by threads on the surface of the rotating shaft 7 to slide on the surface of the fixed rod 9. When the fixed block 8 moves, it drives the sliding rod 14 on the surface, causing the sliding rod 14 to move outward of the frame 1 with the connecting block 13 as the circle. At the same time, it drives the sliding column 17 at the end of the sliding rod 14 to slide on the inner wall of the fixed column 16. This causes the clamping plates 5 on both sides of the worktable 2 to slide on the upper surface of the worktable 2, clamping the workpiece to be processed. This avoids stress concentration when clamping the workpiece, thus ensuring the dimensional accuracy after processing and making the processed workpiece smoother and reducing surface roughness.

[0032] In Example 3, unlike Example 2, the baffle 19, buffer spring 22, and force-bearing plate 21 are used to prevent debris from flying due to cutting force during operation, thus improving the protection of workers. Figures 6-7As shown: A striking post 24 is rotatably installed on the upper rear side of the frame 1, and the striking post 24 is in contact with the surface of the force plate 21. A lower protrusion 25 is fixedly connected to the outer side of the force plate 21. At the same time, one end of a No. 1 spring 26 is fixedly connected to one end of the striking post 24 near the force plate 21, and a collecting plate 23 is fixedly connected to the other end of the No. 1 spring 26. One end of a buffer spring 22 is fixedly connected to the upper surface of the baffle 19, and the other end of the buffer spring 22 is fixedly connected to the force plate 21. The lower surface of the force plate 21 is arc-shaped.

[0033] As the clamping plate 5 slides on the upper surface of the worktable 2, it causes the push block 18 on the surface of the clamping plate 5 to slide on the lower surface of the worktable 2. As the push block 18 contacts the force plate 21, it pushes the force plate 21 to slide on the surface of the moving column 20. At the same time, the buffer spring 22 extends towards the surface of the force plate 21, causing the force plate 21 to extend out from the rear side of the worktable 2. This helps to block the debris generated during the cutting of the workpiece, intercepting the flying debris within the working area, ensuring the safety of the operator, and reducing debris and flying debris. The splashes reduce wear on the device, extending its service life. As the force plate 21 extends, the lower protrusion 25 on the surface of the force plate 21 pushes the striking column 24 to swing around the frame 1. At the same time, the first spring 26 extends towards the surface of the striking column 24. When the lower protrusion 25 strikes the striking column 24 away, the striking column 24 strikes the force plate 21, thereby reducing the residue of dirt on the surface of the force plate 21, keeping the work area clean, and facilitating cleaning and subsequent treatment.

[0034] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
