Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, specifically to a tooling for measuring spring force. Background Technology

[0002] Spring force measurement fixtures are key auxiliary equipment used to test the force performance of spring products. Their core function is to obtain spring force data by applying a specific displacement or load to determine whether the spring meets design standards. As a fundamental elastic element in mechanical systems, the accuracy of spring force measurement directly affects the performance and lifespan of products in many fields such as automobiles, home appliances, and instruments. Therefore, accurate spring force measurement is a crucial step in the spring production process.

[0003] In existing technologies, a combination of a vise and a dial indicator is typically used for inspection. The small compression spring to be inspected is placed between the jaws of the vise, and the vise screw is manually tightened to induce compression. The compression is then read using a dial indicator, while a handheld force gauge is used to measure the reaction force against the other end of the spring. This process determines whether the spring force value meets the standard, thereby adjusting spring production or screening for qualified products. This vise and dial indicator combination can achieve basic force value testing for small-sized springs, meeting the inspection needs in simple scenarios.

[0004] However, existing modular fixtures are mostly composed of multiple parts, resulting in a loose structure and poor stability. Slight wobbling during testing can affect the accuracy of spring force measurements. Furthermore, the lack of a spring positioning and clamping structure means the spring is prone to shifting or slipping during force testing, further leading to inaccurate results. Therefore, it is necessary to propose a fixture for measuring spring force values. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a fixture for measuring spring force. The fixture can be fixed to a spring gauge via mounting holes, making the fixture more stable and ensuring its stability during force measurement. Furthermore, a spring-clamping structure further enhances the stability of the spring fixation.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A tooling for measuring spring force includes a box body, an inclined plate fixedly connected to the top of the box body, a support rod fixedly connected to the top of the inclined plate, and a semi-circular mounting seat fixedly connected to the side wall of the support rod; a T-shaped plate fixedly connected to the top of the support rod, and an inverted L-shaped baffle fixedly connected to the side wall of the T-shaped plate, with one end of the baffle arranged perpendicularly to the box body; and several mounting holes are opened on the box body.

[0007] The technical principles of the above solution are as follows: Secure the fixture to the spring balance via the mounting holes to prevent slippage or displacement of the fixture during subsequent testing. Align one end of the spring with the mounting base and slip it onto the outside of the mounting base. Rotate the tail end of the spring 270° around the mounting base to secure the spring firmly in place, ensuring the stability of the spring during force measurement.

[0008] The above approach has the following beneficial effects: 1. This utility model uses mounting holes to fix the tooling and spring force gauge, making the tooling more stable when measuring spring force. The spring clamping structure is set to firmly fix the spring on the mounting base, ensuring the stability of the spring during the force detection process.

[0009] 2. In this utility model, the semi-circular mounting base facilitates the installation of the spring, and the arc-shaped design allows the spring to be directly inserted from the side, making the installation process smoother and improving the convenience of spring installation.

[0010] 3. In this utility model, several mounting holes form a multi-point positioning reference, which can quickly align the tooling with the force position of the spring balance without the need for additional positioning tools, thereby improving the installation positioning accuracy and efficiency.

[0011] Furthermore, a chassis is fixedly connected to the inner wall of each mounting hole, and each chassis sidewall has a sliding groove. Several rotating shafts are rotatably fitted to the top of each chassis, and gears are coaxially fixedly connected to each shaft. Gear plates mesh with the outer sides of each gear, and these gear plates slide against the chassis. Each gear plate is equipped with a guide assembly for guiding the gear plates. A drive assembly for driving the gears to rotate is located on the top of each chassis.

[0012] Beneficial effects: Since the gears mesh with their adjacent toothed plates, the gears can drive the toothed plates to move synchronously, ensuring the stability of power transmission, making the tooling structure more compact, the operation more coherent, and ensuring the convenience of operation when detecting spring force.

[0013] Furthermore, the drive assembly includes a rotating rod and a gear plate, with the rotating rod fixedly connected to the gear plate; a slot is opened on the outer wall of the box, and the rotating rod extends out of the box through the sliding groove and the slot, and slides with the sliding groove and the slot; the side of the gear away from the gear plate meshes with the gear plate.

[0014] Beneficial effects: The groove provides space for the rotating rod to rotate. Since the rotating rod is fixedly connected to the gear plate, rotating the rotating rod can drive the gear plate to rotate. Since the gear plate meshes with several gears, the gear plate drives all the gears to rotate simultaneously. The gears can drive their adjacent gear plates to move synchronously. The position of the rotating rod can be flexibly adjusted as needed, improving the ease of operation.

[0015] Furthermore, the guide assembly includes several guide blocks, each with a guide groove on its toothed plate. The guide grooves slide in cooperation with the adjacent guide blocks, and the bottoms of the guide blocks are fixedly connected to the chassis.

[0016] Beneficial effects: The sliding fit between the guide block and the guide groove restricts the path direction of the toothed plate's movement, preventing the path from deviating when the toothed plate moves and ensuring that the toothed plate slides smoothly along the preset path.

[0017] Furthermore, several toothed plate sidewalls are sequentially fitted together to form adjustment holes, which are connected to mounting holes.

[0018] Beneficial effects: The synchronous sliding adjustment of the toothed plate adjusts the opening of the adjustment hole, improving the applicability of the tooling. The adjustment of the opening can be achieved by rotating the rod, simplifying the tooling fixing process.

[0019] Furthermore, the outer wall of the inclined plate is engraved with spring specification scale lines, and the scale values ​​of the spring specification scale lines decrease sequentially from top to bottom.

[0020] Beneficial effects: The spring specification scale lines allow for a direct view of the spring's diameter. The scale values ​​decrease sequentially from top to bottom, facilitating quick reading and alignment. This makes it easier for operators to record spring data and improves the efficiency and convenience of force value testing.

[0021] Furthermore, several U-shaped buckles are fixedly connected to the top wall of the slot, and hooks are fixedly connected to the top of the rotating rod.

[0022] Beneficial effect: After the rotating rod is rotated to the appropriate position, the hook is engaged with the adjacent U-shaped buckle to fix the position of the rotating rod and ensure the stability of the rotating rod during the testing process.

[0023] Furthermore, a tapered seat is fixedly connected to the end of the mounting base away from the support rod.

[0024] Beneficial effects: The small-diameter end of the tapered seat faces away from the mounting base, which guides the spring installation and allows it to be quickly inserted into the mounting base without the need for precise alignment, thus improving the efficiency of spring installation.

[0025] Furthermore, the top of the box has several grooves, each containing a sliding slider.

[0026] Beneficial effects: The slider can slide along the groove to adjust its position, and can be adjusted according to the position and distance of the spring tail end to position the spring tail end, which facilitates real-time recording of the influence of the direction and distance of the spring's downward pressure on the force value.

[0027] Furthermore, a limit groove is provided on the side wall of the mounting base, and a baffle is detachably connected inside the limit groove.

[0028] Beneficial effects: The baffle and the limiting groove are detachably connected. After the spring is inserted, the baffle is installed to limit the lateral movement of the spring, prevent the spring from deviating, affect the result of the influence value detection, and improve the stability of the spring fixation.

[0037] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0038] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] The following detailed description illustrates the specific implementation method: Example 1: like Figure 1 As shown, a fixture for measuring spring force includes a housing 3. An inclined plate 6 is integrally formed on the top of the housing 3, and a support rod 1 is integrally formed on the top of the inclined plate 6. A semi-circular mounting base 5 is integrally formed on the side wall of the support rod 1. A T-shaped plate 17 is integrally formed on the top of the support rod 1, and an inverted L-shaped baffle 4 is integrally formed on the side wall of the T-shaped plate 17, with one end of the baffle 4 perpendicular to the housing 3. Several mounting holes 2 are provided on the housing 3. In this embodiment, the fixture is made entirely of ABS material.

[0041] Specifically, when using this tooling to measure spring force, the tooling is fixed to the spring gauge through the mounting hole 2 to prevent displacement of the tooling during the test. Then, one end of the spring to be tested is aligned with the semi-circular mounting base 5. In this embodiment, the radius of the semi-circular mounting base 5 is 4mm. The spring is fitted onto the outside of the mounting base 5 so that the inner ring of the spring is in contact with the surface of the mounting base 5. The tail end of the spring is rotated 270° around the mounting base 5 to fix the spring on the mounting base 5. At this time, because the inverted L-shaped baffle 4 is perpendicular to the box 3 at one end, it blocks the spring, preventing the spring from springing outward due to elastic recovery during the test. Figure 7 As shown. In this embodiment, the force value of the spring is measured by compressing the other end (free end) of the spring from above using the moving pressure head of the spring balance.

[0042] This invention achieves a secure fixation between the tooling and the spring force gauge through the mounting hole 2, making the tooling more stable when measuring spring force, ensuring the stability of the force measurement process, and further improving the accuracy of force measurement. The spring's clamping structure fixes the spring on the mounting base, ensuring the spring's stability during force measurement.

[0043] Example 2: like Figure 2 As shown, the difference from Embodiment 1 is that the inner wall of the mounting hole 2 is integrally formed with a base 16, and the side wall of the base 16 has a sliding groove 24. Several rotating shafts 18 are rotatably fitted to the top of the base 16, and gears 7 are coaxially welded to each rotating shaft 18. Toothed plates 8 mesh with the outer sides of each gear 7, and the toothed plates 8 are slidably fitted with the base 16. The side walls of the several toothed plates 8 are sequentially fitted to form an adjustment hole 9, which communicates with the mounting hole 2.

[0044] The top of the chassis 16 is equipped with a drive assembly for rotating the gear 7. The drive assembly includes a rotating rod 10 and a gear disk 15, with the rotating rod 10 and gear disk 15 integrally formed. The side of the gear 7 furthest from the gear plate 8 meshes with the gear disk 15. Figure 5 As shown, a slot 13 is formed on the outer wall of the box body 3. The rotating rod 10 extends through the slide groove 24 and the slot 13 to the outside of the box body 3, and slides in cooperation with the slide groove 24 and the slot 13.

[0045] Specifically, since the rotating rod 10 and the gear plate 15 are integrally formed, rotating the rotating rod 10 can cause the gear plate 15 to rotate accordingly. Since one side of the gear 7 is engaged with the gear plate 15 and the other side is engaged with the adjacent gear plate 8, the gear plate 15 drives all the gears 7 to rotate accordingly. The gears 7 drive the corresponding gear plates 8 to move synchronously, thereby enlarging or shrinking the diameter of the adjusting hole 9.

[0046] A fixing hole is opened in the middle of the chassis 16, and the adjusting hole 9 is connected to the fixing hole. At this time, the tooling can be fixed to the spring force gauge. In this embodiment, bolts are used to fix the tooling. Specifically, the bolts are passed through the mounting hole 2, the adjusting hole 9 and the fixing hole in sequence, and the bolts are threaded to the top of the spring force gauge. Then, the rotating rod 10 is rotated to adjust the opening of the adjusting hole 9 so that the adjusting hole 9 can fit tightly with the bolt thread.

[0047] Each toothed plate 8 is provided with a guide assembly for guiding the toothed plate 8. The guide assembly includes several guide blocks 11. Each toothed plate 8 has a guide groove 14, which slides in cooperation with the adjacent guide block 11. The bottom of each guide block 11 is integrally formed with the chassis 16.

[0048] Specifically, the sliding engagement between the guide groove 14 and the guide block 11 restricts the movement path and direction of the toothed plate 8, preventing the toothed plate 8 from deviating from its sliding path and ensuring that the toothed plates 8 move synchronously along the preset path.

[0049] like Figure 3 and Figure 5 As shown, the outer wall of the inclined plate 6 is engraved with spring specification scale lines 22, and the scale values ​​of the spring specification scale lines 22 decrease sequentially from top to bottom. The scale values ​​of the spring specification scale lines 22 decrease sequentially from top to bottom according to the diameter of the spring. By comparing the spring with the scale, the diameter data of the spring can be recorded quickly. The sequential decrease of the scale values ​​from top to bottom can quickly align the spring for reading, improving the detection efficiency.

[0050] like Figure 3 , Figure 5 and Figure 6 As shown, several U-shaped buckles 25 are fixedly connected to the top wall of the slot 13, and hooks 12 are fixedly connected to the top of the rotating rod 10. In this embodiment, the hooks 12 are made of elastic material. When the position of the rotating rod 10 is determined, since the hooks 12 are made of elastic material, the hooks 12 can be adjusted to a suitable position to engage with the adjacent U-shaped buckles 25. The U-shaped buckles 25 limit the shaking of the rotating rod 10 and ensure the stability of the rotating rod 10 during force detection.

[0051] like Figure 4 and Figure 5 As shown, a tapered seat 19 is integrally formed at the end of the mounting base 5 away from the support rod 1. The small-diameter end of the tapered seat 19 faces the outside of the mounting base 5. When installing the spring, the spring can be pushed to the mounting base 5 along the tapered seat 19 without deliberately aligning the position, simplifying the spring installation operation.

[0052] like Figure 5 As shown, the top of the box 3 also has several grooves 21, and sliders 20 are slidably fitted in each groove 21. The sliders 20 can slide along the grooves 21. By moving the sliders 20 to the position after the spring is compressed, the position can be recorded, thereby observing the influence of different distances and directions on the spring force value.

[0053] like Figure 5 As shown, the side wall of the mounting base 5 has a limiting groove, and a baffle 23 is detachably connected inside the limiting groove. The baffle 23 can be installed after the spring is installed into the mounting base 5, further restricting the lateral movement of the spring and improving the stability of the spring.

[0054] In this invention, the opening of the adjustment hole 9 can be flexibly adjusted as needed, thereby quickly achieving precise alignment and stable fixation of the tooling and the spring force gauge, effectively simplifying the fixing operation process and improving the adaptability and operational efficiency of the tooling fixation.

[0055] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
