Description

Technical Field

[0001] This utility model relates to the field of spring deformation force detection technology, and in particular to a compression spring deformation force detection device. Background Technology

[0002] After production, springs need to be tested for their deformation force. This is mainly done by applying pressure to the top to cause the spring to deform and recording the compression amount under each load level.

[0003] Since most springs are placed directly on the base surface, if the spring's position is unstable, the downward pressure will cause uneven force, and the spring may experience abnormal readings, tipping over, or popping out during compression. Summary of the Invention

[0004] This utility model discloses a compression spring deformation force detection device, which aims to solve the technical problem that if the spring is not placed in an unstable position, the downward force will be uneven, and the spring may cause abnormal detection values, tilting or popping out during the compression process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A compression spring deformation force detection device includes a limiting mechanism and a lifting mechanism. The lifting mechanism is connected to the bottom end of the limiting mechanism. The limiting mechanism includes: a circular support with a main base fixedly connected to its outer periphery via a side bracket; multiple waist-shaped grooves equidistantly arranged on the circular support; a circular snap-fit ​​frame with multiple arc-shaped grooves equidistantly arranged on its top inner wall and a gear ring fixedly connected to its outer circumference; a gear that movably meshes with the gear ring and a motor fixedly connected to its bottom outer wall; a circular sliding sleeve that movably snaps onto the outside of the circular snap-fit ​​frame; and multiple abutments, each with a slide bracket two fixedly connected to its bottom end, and each slide bracket two movably snaps onto each arc-shaped groove. The top ends of the multiple abutments pass through the multiple waist-shaped grooves, and the outer circumference of the abutments movably fits against the inner wall of the waist-shaped groove. The limiting mechanism further includes: an annular base, which is fixedly connected to the bottom outer wall of the circular sliding sleeve; and a motor bracket, which is fixedly connected to one side outer wall of the annular base, and the motor is fixedly installed on the bottom outer wall of the motor bracket, with its output end passing through the motor bracket and connected to the gear.

[0006] By setting a limiting mechanism, after the spring is placed, the motor drives multiple push rods to expand outward simultaneously until they just touch the inner wall of the spring, thus providing a limiting effect on the bottom of the spring. With the dual effects of ensuring uniform force distribution and limiting the bottom of the spring, the situation where the spring offset cannot be detected in the early stage can be avoided. At the same time, it can be used for springs of different diameters.

[0007] In a preferred embodiment, two longitudinal guide rails are symmetrically fixedly connected to the top outer wall of the main base, and a slide is movably connected to both longitudinal guide rails. A pressure seat is fixedly connected to the center of the slide, and the pressure seat is located directly above the circular support. The lifting mechanism includes: a hollow base, with an annular base movably connected to the inner wall of the top of the hollow base; a hydraulic rod, fixedly connected to the inner wall of the bottom of the hollow base, and its output end fixedly connected to the outer wall of the bottom of the annular base; and multiple limiting rods, equidistantly fixedly connected to the outer wall of the bottom of the annular base. The lifting mechanism further includes: multiple limiting plates, fixedly connected to the inner wall of the hollow base, and multiple limiting rods respectively movably inserted into the multiple limiting plates; a contact sensing rod, the bottom end of which is fixedly connected to the inner wall of the hollow base through a fixing frame, and the top end of which passes through a circular snap-fit ​​frame and a circular support.

[0008] With a lifting mechanism, a control signal is sent when the bottom of the pressure seat contacts the top of the contact sensing rod, driving the annular base to move down along the inner wall of the hollow base. The top of the abutment rod is completely submerged in the waist-shaped groove, thus not obstructing the downward pressure position of the pressure seat and ensuring the accuracy of deformation force detection.

[0009] In a preferred embodiment, the limiting mechanism further includes: a plurality of grooves disposed on the outer circumference of each abutment; and a plurality of screw holes disposed on the inner top wall of each abutment. The limiting mechanism further includes: multiple rubber sleeves, which are respectively fitted onto multiple abutment rods and located in the groove; multiple bolts, which are respectively engaged in multiple screw holes, and one side of the bolts is movably attached to the top outer wall of the rubber sleeve.

[0010] By setting a limiting mechanism and fitting a rubber sleeve into the groove of each abutment, the friction with the spring can be increased, further ensuring the support stability of the bottom of the spring. At the same time, the limiting structure of the rubber sleeve can reduce the difficulty of replacing the rubber sleeve.

[0011] As described above, a compression spring deformation force detection device includes a limiting mechanism and a lifting mechanism. The lifting mechanism is connected to the bottom end of the limiting mechanism. The limiting mechanism includes: a circular support with a main base fixedly connected to its outer circumference via a side bracket; multiple waist-shaped grooves equidistantly arranged on the circular support; a circular snap-fit ​​frame with multiple arc-shaped grooves equidistantly arranged on its top inner wall, and a gear ring fixedly connected to its outer circumference; a gear that movably meshes with the gear ring, and a motor fixedly connected to its bottom outer wall; a circular sliding sleeve that movably snaps onto the outside of the circular snap-fit ​​frame; and multiple abutments, each with a slide bracket two fixedly connected to its bottom end, and each slide bracket two movably snaps into each arc-shaped groove. The top ends of the multiple abutments pass through the multiple waist-shaped grooves, and the outer circumference of the abutments movably fits against the inner wall of the waist-shaped groove. The compression spring deformation force detection device provided by this utility model has the technical effect of ensuring uniform force distribution and limiting the bottom end of the spring, thus avoiding the situation where normal monitoring cannot be achieved due to spring displacement in the initial stage of detection.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] The compression spring deformation force detection device disclosed in this utility model is mainly used in the scenario of spring deformation force detection.

[0019] Reference Figures 1-3 A compression spring deformation force detection device includes a limiting mechanism 4 and a lifting mechanism 5. The lifting mechanism 5 is connected to the bottom end of the limiting mechanism 4. The limiting mechanism 4 includes: A circular support 401 has a main base 7 fixedly connected to its outer periphery via a side bracket 6; Multiple waist-shaped grooves 402 are equidistantly arranged through the circular support 401; The circular clip bracket 411 has multiple arc-shaped grooves 404 equidistantly arranged on the inner wall of its top end, and a toothed ring 403 is fixedly connected to its outer circumference. Gear 405 is movably meshed with gear ring 403, and motor 406 is fixedly connected to its bottom outer wall; The circular sliding sleeve 408 is movable and attached to the outside of the circular clip bracket 411; Multiple abutment rods 407 are fixedly connected to the bottom of each slide 416, and each slide 416 is movably engaged in each arc-shaped groove 404. The tops of the multiple abutment rods 407 pass through multiple waist-shaped grooves 402, and the outer circumference of the abutment rod 407 is movably fitted against the inner wall of the waist-shaped groove 402. A spring is placed on the top of a circular support 401. The deformation force is detected by the pressure provided by the top of the spring. After the spring is placed, the motor 406 drives the gear 405 to rotate, which in turn drives the gear ring 403 to rotate, thereby changing the position of the arc-shaped groove 404. The multiple waist-shaped grooves 402 limit the multiple abutment rods 407 to expand outward simultaneously until they just abut against the inner wall of the spring. This provides a limiting effect on the bottom of the spring and ensures that the spring is in the center position and that the force is evenly distributed. With this structure, under the dual effect of ensuring even force distribution and limiting the bottom of the spring, the situation where the spring is offset in the early stage of detection and cannot be monitored normally can be avoided.

[0020] Reference Figure 2 In a preferred embodiment, the limiting mechanism 4 further includes: The annular base 410 is fixedly connected to the outer wall of the bottom end of the circular sliding sleeve 408; The motor bracket 409 is fixedly connected to one side of the outer wall of the annular base 410, and the motor 406 is fixedly installed on the bottom outer wall of the motor bracket 409, with its output end passing through the motor bracket 409 and connected to the gear 405.

[0021] Reference Figure 4 In a preferred embodiment, the limiting mechanism 4 further includes: Multiple grooves 415 are provided on the outer circumferential wall of each abutment 407; Multiple screw holes 414 are provided on the inner wall of the top end of each abutment 407.

[0022] Reference Figure 4 In a preferred embodiment, the limiting mechanism 4 further includes: Multiple rubber sleeves 413 are respectively fitted onto multiple abutment rods 407 and located within the groove 415; Multiple bolts 412 are respectively engaged in multiple screw holes 414, and one side of the bolt 412 is movably attached to the top outer wall of the rubber sleeve 413. By setting the rubber sleeve 413 to fit into the groove 415 of each abutment 407, when multiple abutments 407 are supported on the inner wall of the spring, the rubber sleeve 413 is just located at the contact surface, thereby increasing the friction with the spring and further ensuring the support stability of the bottom of the spring. Through the bolt 412 limiting structure, the rubber sleeve 413 can be replaced by removing the bolt 412 after the rubber sleeve 413 is severely worn, reducing the difficulty of replacing the rubber sleeve 413.

[0023] Reference Figure 1 In a preferred embodiment, two longitudinal guide rails 1 are symmetrically fixedly connected to the top outer wall of the main base 7, and slides 2 are movably connected to both longitudinal guide rails 1. A pressure seat 3 is fixedly connected to the center of the slides 2, and the pressure seat 3 is located directly above the circular support 401.

[0024] Reference Figure 2 In a preferred embodiment, the lifting mechanism 5 includes: Hollow base 501, annular base 410 is movably connected to the inner wall of the top of hollow base 501; The hydraulic rod 502 is fixedly connected to the inner wall of the bottom end of the hollow base 501, and its output end is fixedly connected to the outer wall of the bottom end of the annular base 410. Multiple limiting rods 506 are fixedly connected at equal intervals to the bottom outer wall of the annular base 410.

[0025] Reference Figure 2 In a preferred embodiment, the lifting mechanism 5 further includes: Multiple limiting plates 505 are fixedly connected to the inner wall of the hollow base 501, and multiple limiting rods 506 are respectively movably inserted into the multiple limiting plates 505; The bottom end of the contact sensing rod 503 is fixedly connected to the inner wall of the hollow base 501 by the fixing bracket 504, and its top end passes through the circular snap bracket 411 and the circular support 401. As the pressure seat 3 continues to move down, when its bottom end contacts the top end of the contact sensing rod 503, a control signal is emitted, the hydraulic rod 502 is activated, and the annular base 410 is driven to move down along the inner wall of the hollow base 501. Multiple limiting rods 506 move within the limiting plate 505 to provide a limiting function. After moving down to the fixed position, the top end of the abutment rod 407 is completely submerged in the waist-shaped groove 402, so as not to block the downward pressure position of the pressure seat 3 and ensure the accuracy of deformation force detection.

[0026] Working principle: The spring is placed on the top of the circular support 401. The deformation force is detected by the pressure provided by the top of the spring. After the spring is placed, the motor 406 drives the gear 405 to rotate, which in turn drives the gear ring 403 to rotate, changing the position of the arc groove 404. The multiple waist-shaped grooves 402 limit the expansion of multiple push rods 407 to the outside until they just touch the inner wall of the spring. This provides a limiting effect on the bottom of the spring and ensures that the spring is in the center position, ensuring that the force is evenly distributed. With this structure, under the dual effect of ensuring even force distribution and limiting the bottom of the spring, the situation where the spring is offset in the early stage of detection and cannot be monitored normally can be avoided.

[0027] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
