Description
Technical Field
[0001] This utility model relates to the field of stamping positioning technology, and in particular to a precision spring unit stamping positioning device. Background Technology
[0002] A spring unit typically refers to a flexible, thin metal sheet assembly. It is generally sheet-like and comes in various shapes, such as rectangular, circular, or irregular. Its size varies depending on the specific application.
[0003] Spring elements typically require specific shapes and dimensions to meet functional requirements in various applications. For example, in electronic devices, springs need specific curved shapes to ensure good contact with other components and achieve functions such as conductivity. Stamping processes can precisely machine springs into the required shapes, ensuring their performance and reliability.
[0004] Traditional spring unit stamping devices lack effective positioning mechanisms when stamping spring units of different sizes, making precise positioning difficult and prone to positional deviations during the stamping process, thus increasing the scrap rate. Furthermore, traditional positioning methods are inflexible and cannot meet the needs of spring units of various sizes, negatively impacting production efficiency and product quality. In addition, overload situations can easily occur during the stamping process due to equipment instability or improper operation, causing damage to the equipment and spring units. The lack of an effective overload protection mechanism not only increases equipment maintenance costs but also affects production continuity. Therefore, to address these problems, a precision spring unit stamping positioning device is proposed. Utility Model Content
[0005] To overcome the above deficiencies, this utility model provides a precision spring unit stamping and positioning device, which aims to improve the problems of existing technology that cannot position and fix spring units of different sizes and cannot solve the overload problem of impact mechanism.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a precision spring unit stamping and positioning device, comprising a base, an installation plate fixedly connected to the top of the base, a placement block detachably connected to the top of the installation plate, a motor fixedly connected to the bottom middle of the placement block, a rotating plate fixedly connected to the drive end of the motor, a rotating roller rotatably connected to both ends of the rotating plate away from the motor, a U-shaped block rotatably connected to the end of the rotating roller away from the motor, a slider fixedly connected to the top of the U-shaped block, a groove provided on the middle side of the two sliders, a rotating shaft fixedly connected to the middle of the slider, an L-shaped clamping block rotatably connected to the outside of the rotating shaft, a spring fixedly connected to the side of the L-shaped clamping block away from the motor, sliding grooves provided at the four corners of the top of the placement block, and a limiting component for fixing spring units of different sizes provided in the middle of the top of the placement block;
[0007] Furthermore, by starting motor one, the motor drives the rotating plate to rotate. Through the rotating rollers connected to the two ends of the rotating plate, the U-shaped block is pulled to slide in the groove. The U-shaped block drives the groove to slide in the groove at the same time, so that the bottom end of the L-shaped clamping block contacts the side of the spring unit opposite to the groove. This achieves centering and positioning of the left and right sides of the spring unit of different sizes. At the same time as the bottom end of the L-shaped clamping block contacts the spring unit, the L-shaped clamping block will squeeze the spring and rotate to position and fix the two square positions of the spring unit.
[0008] As a further description of the above technical solution: the limiting component includes a long groove, the top center of the placement block is provided with a long groove, and curved clamps are slidably connected to both the front and rear sides of the interior of the long groove, and three springs are fixedly connected to the adjacent side of the two curved clamps.
[0009] Furthermore, by pressing the curved surface of the spring unit against the curved surface of the clamping plate, the curved surface clamping plate slides to both sides, and the spring unit is clamped and fixed in the front and rear positions through the elastic connection of the second spring.
[0010] As a further description of the above technical solution: A support frame is fixedly connected to the top of the base, two support plates are fixedly connected to the middle of the top of the support frame, a motor II is fixedly connected to the top of the two support plates, an eccentric disk is fixedly connected to the outside of the motor II, a collar is rotatably connected to the outside of the eccentric disk, a connector I is fixedly connected to the middle of the rear side of the collar, two rotating rods I are rotatably connected to the outside of the connector I, a central shaft is rotatably connected to the middle of the top of the two rotating rods I, two rotating rods II are rotatably connected to the outside of the central shaft, a connector II is fixedly connected to the bottom of the collar, a V-block is rotatably connected to the outside of the connector II, a U-shaped shaft is rotatably connected to the top of the V-block, a slide rod is fixedly connected to the rear end of the U-shaped shaft, and a spring III is sleeved on the outside of the slide rod;
[0011] Furthermore, when an overload occurs in the stamping mechanism, the connecting piece fixed to the side of the collar will transmit the overload pressure to the spring three through the rotating rod one and the central shaft. After being compressed, the spring three will contract and absorb the compression force. Then, it will drive the central shaft limited by the rotating rod one and the rotating rod two to reset through its own elasticity, thereby preventing the stamping mechanism from overloading.
[0012] As a further description of the above technical solution: the middle part of the V-shaped block is rotatably connected to a support member, the bottom end of the support member is detachably connected to a punch head, the bottom ends of the two support plates on their adjacent sides are fixedly connected to a limit ring, and the outer middle part of the support member is slidably connected to the middle part of the limit ring.
[0013] Furthermore, the position of the swinging support is limited by a limiting ring, thereby enabling the stamping head to slide linearly up and down for stamping operations. The detachable nature of the stamping head allows for the replacement of different types to meet various processing requirements.
[0014] As a further description of the above technical solution: The front and rear ends of the U-shaped block are externally slidably connected to the inner wall of the groove, and the bottom end of the groove is slidably connected to the top end of the placement block;
[0015] Furthermore, by using a groove to define the position of the U-shaped blocks, the two U-shaped blocks can slide stably in the center, and clamp and position spring units of different lateral dimensions. The U-shaped blocks slide on the top of the placement block via a groove, and the side reaction indicates that the U-shaped blocks can stably drive the groove to slide in the center.
[0016] As a further description of the above technical solution: the outer side of the L-shaped clamping block is slidably connected to the inner wall of the groove, and one end of the spring away from the L-shaped clamping block is fixedly connected to the inner wall of the groove;
[0017] Furthermore, by using a spring to press against the L-shaped clamping block with the groove as the center, the L-shaped clamping block can contact the side of the spring unit while rotating stably downwards, clamping and positioning the top of the spring unit, thus fixing the two squares.
[0018] As a further description of the above technical solution: the bottom ends of the two rotating rods are rotatably connected to the middle of the rear end of the V-block, and the outer side of the slide rod is slidably connected to the middle of the central shaft;
[0019] Furthermore, by rotating rod two at one end of the V-block, a corner is formed between rotating rod one connected to the top of the central shaft, which can stably drive the central shaft to slide on the outside of the slide rod.
[0020] As a further description of the above technical solution: the front end of the spring three is fixedly connected to the middle part of the central shaft, and the rear end of the spring three is fixedly connected to the rear end of the slide rod;
[0021] Furthermore, the pressure transmitted by the central shaft can be absorbed by the spring three, and then the central shaft defined by the rotating rod one and the rotating rod two is reset by its own elastic force.
[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, by pressing the curved surface of the curved clamping plate with the spring unit, the curved clamping plate is driven to slide in the long groove to adapt to the width of the spring unit. Then, with the starter motor, the groove is pulled to slide relative to each other, so that the bottom end of the L-shaped clamping block and the opposite side of the groove are fixed to the side of the spring unit. At the same time as the bottom end of the L-shaped clamping block contacts the spring unit, it rotates to clamp and fix the top two sides of the spring unit. This realizes the centering and positioning of spring units of different sizes, and can fix the top two sides of the spring unit, ensuring that the spring maintains a stable position during processing and reducing the scrap rate caused by position deviation.
[0024] 2. In this utility model, the eccentric disk is driven to rotate eccentrically by the second motor, so that the collar indirectly drives the support to perform stamping work on the spring unit through the second connector, the V-block, and the support. In addition, with the sliding rod limited in the middle of the first and second rotating rods and the spring three, when the collar rotates too much and floats, the overload rotation force is transmitted to the spring three through the first connector, so as to realize overload protection, which helps to maintain the stability of the stamping process, reduce the generation of scrap due to equipment failure or improper operation, and improve product quality and production efficiency.

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.
[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a precision spring unit stamping and positioning device, comprising a base 1, which serves as the foundation of the entire device and supports other components. A mounting plate 2 is fixed to the top of the base 1, providing an installation position for a placement block 3. The top of the mounting plate 2 is detachably connected to the placement block 3, which is used to place the spring unit.

Rotating rollers 6 are rotatably connected to both ends of the rotating plate 5 furthest from the motor 4, and these rollers 6 function when the rotating plate 5 rotates.
[0034] refer to Figure 2 , Figure 3 A U-shaped block 7 is rotatably connected to the end of the rotating roller 6 away from the motor 4. The U-shaped block 7 slides within the groove 13 under the pull of the rotating roller 6, causing the slider 8 to move. The top of the U-shaped block 7 is fixedly connected to the slider 8, which provides an installation position for the groove 9 and the rotating shaft 10. A groove 9 is formed on one side of the middle of the two sliders 8, providing a sliding track for the L-shaped clamping block 11. The bottom end of the groove 9 is slidably connected to the top of the placement block 3, and the groove 9 slides relative to the surface of the placement block 3.
[0035] A rotating shaft 10 is fixedly connected to the middle of the slider 8, providing rotational support for the L-shaped clamp 11. The L-shaped clamp 11 is rotatably connected to the outside of the rotating shaft 10, and its outer side is slidably connected to the inner wall of the groove 9. The L-shaped clamp 11 slides within the groove 9, clamping and fixing the sides and top of the spring unit. A spring 12 is fixedly connected to the side of the L-shaped clamp 11 away from the motor 4, and the end of the spring 12 away from the L-shaped clamp 11 is fixedly connected to the inner wall of the groove 9. The groove 9 provides elastic support for the L-shaped clamp 11, causing it to tilt upwards in the initial state and providing clamping force when clamping the spring unit. Slide grooves 13 are provided at the four corners of the top of the placement block 3. The front and rear ends of the U-shaped block 7 are slidably connected to the inner wall of the slide grooves 13, which provide sliding tracks for the front and rear ends of the U-shaped block 7.
[0036] A limiting component for fixing spring units of different sizes is provided at the top center of the placement block 3. The limiting component includes a long groove 14, which is a long strip-shaped groove 9. Curved clamping plates 15 are slidably connected to both the front and rear sides of the interior of the long groove 14. The curved clamping plates 15 are L-shaped plates, and the opposite surfaces of the two plates are curved. Three springs 16 are fixedly connected to the adjacent sides of the two curved clamping plates 15. The function of the springs 16 is to provide elastic connection for the curved clamping plates 15, so that they can clamp spring units of different sizes.
[0037] Figure 4 , Figure 5 A support frame 17 is fixedly connected to the top of the base 1, providing support for components such as the support plate 18 and the second motor 19. Two support plates 18 are fixedly connected to the middle of the top of the support frame 17, providing an installation position for the second motor 19 and supporting the limiting ring 33. The second motor 19 is fixedly connected to the top of the two support plates 18, with its drive housing fixed to the outside of one of the support plates 18, and its drive shaft passing through the support plate 18. An eccentric disc 20 is fixedly connected to the outside of the second motor 19, driven by the second motor 19 to rotate, causing the collar 21 to rotate.
[0038] A collar 21 is rotatably connected to the outside of the eccentric disk 20. The collar 21 rotates outside the eccentric disk 20, driving the stamping mechanism through connector 1 22 and connector 26. Connector 1 22 is fixedly connected to the middle of the rear side of the collar 21. Connector 1 22 connects the collar 21 and rotating rod 1 23, converting the rotation of the collar 21 into up-and-down swinging. Two rotating rods 1 23 are rotatably connected to the outside of connector 1 22. Rotating rods 1 23 connect connector 1 22 and central shaft 24, transmitting pressure. The central shaft 24 is rotatably connected to the middle of the top of the two rotating rods 1 23, providing rotational support for rotating rods 1 23 and rotating rod 26.
[0039] Two rotating rods 25 are rotatably connected to the outside of the central shaft 24. Rotating rods 25 connect the central shaft 24 and the V-block 27, transmitting pressure. A connecting piece 26 is fixedly connected to the outer bottom end of the collar 21. A V-block 27 is rotatably connected to the outside of the connecting piece 26, connecting the collar 21 and the V-block 27, transmitting the movement of the collar 21. The bottom ends of the two rotating rods 25 are rotatably connected to the middle of the rear end of the V-block 27. The V-block 27 slides linearly under the action of the connecting piece 26 and the rotating rods 25, driving the support member 31 and the stamping head 32 to work.
[0040] A U-shaped shaft 28 is rotatably connected to the top of the V-block 27. The U-shaped shaft 28 connects the slide rod 29 and the V-block 27, providing support for the slide rod 29. The rear end of the U-shaped shaft 28 is fixedly connected to the slide rod 29. The slide rod 29 is slidably connected to the middle of the central shaft 24. The slide rod 29 slides on the central shaft 24, transmitting pressure through the spring 30, which also connects the U-shaped shaft 28 and the central shaft 24. The spring 30 is sleeved on the outside of the slide rod 29. The front end of the spring 30 is fixedly connected to the middle of the central shaft 24, and the rear end of the spring 30 is fixedly connected to the rear end of the slide rod 29. When the stamping mechanism is overloaded, the spring 30 absorbs the overload pressure and drives the relevant components to reset, preventing the stamping mechanism from overloading.
[0041] A support member 31 is rotatably connected to the middle of the V-block 27, supporting the stamping head 32. The support member 31 transmits the movement of the V-block 27 to the stamping head 32. The bottom end of the support member 31 is detachably connected to the stamping head 32, which performs stamping work on the spring unit placed at the top of the block 3. Limiting rings 33 are fixedly connected to the bottom ends of the two support plates 18 on their adjacent sides. The outer middle of the support member 31 is slidably connected to the middle of the limiting ring 33. The limiting ring 33 provides sliding limit for the support member 31, ensuring the movement direction of the stamping head 32.
[0042] Working Principle: In use, the spring unit is pressed against the curved surface of the curved clamping plate 15, causing the curved clamping plate 15 to slide to both sides. Through the elastic connection of spring 16, the front and rear positions of the spring unit are clamped and fixed. Then, motor 4 is started, causing the rotating plate 5 to rotate. Through the rotating rollers 6 connected to the two ends of the rotating plate 5, the U-shaped block 7 slides relative to each other within the slide groove 13. The U-shaped block 7 drives the slider 8 to slide relative to each other, allowing the bottom end of the L-shaped clamping block 11 to contact the side of the spring unit opposite to the slider 8, clamping and fixing it. The cooperation of the curved clamping plate 15 and the L-shaped clamping block 11 achieves centered positioning of spring units of different sizes. Furthermore, since the L-shaped clamping block 11 is initially supported by spring 12 and tilted upwards, when the bottom end of the L-shaped clamping block 11 contacts the spring unit, it presses against spring 12 and rotates to clamp and fix the top two sides of the spring unit, effectively ensuring that the spring maintains a stable position during processing.
[0043] After the spring piece unit is fixed, motor 219 is started. Motor 219 drives the collar 21 to rotate through the transmission shaft, causing the collar 21 to rotate at high speed on the inner wall of connector 22, thus realizing the up-and-down swing of connector 22. When connector 22 swings up and down, it will slide linearly through connector 26 and V-block 27, causing the stamping head 32 fixed to support 31 to descend and stamp the spring piece unit at the top of block 3. When the stamping mechanism is overloaded, connector 22 fixed to the side of collar 21 will transmit the overload pressure to spring 30 through rotating rod 23 and central shaft 24. Spring 30 will contract after being compressed, absorbing the compression force, and then use its own elasticity to drive rotating rod 23 and rotating rod 25 to reset the central shaft 24, thereby preventing the stamping mechanism from being overloaded.
[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
