Description

Technical Field

[0001] This utility model belongs to the field of irregular springs, specifically relating to an adapter mechanism and a torque measuring device. Background Technology

[0002] In numerous fields such as machinery manufacturing, automotive industry, aerospace, and electronic equipment, springs, as core elastic components, directly determine the reliability, stability, and service life of the entire equipment. Compared to regularly shaped cylindrical helical springs, irregularly shaped springs are widely used because they can adapt to complex installation spaces, achieve special elastic force output curves, and meet personalized working conditions. To determine whether an irregularly shaped spring can meet the application requirements, it is necessary to determine whether the irregularly shaped spring can provide the required torque when deformed to a specific angle. This is one of the important indicators for evaluating the practicality of irregularly shaped springs.

[0003] However, irregularly shaped springs differ from conventional springs in that their shapes are quite unique. Current technology lacks equipment capable of adapting to irregularly shaped springs and driving them to rotate and deform to a predetermined angle. This makes it impossible for existing technology to determine whether an irregularly shaped spring can provide the required torque at a specific angle, thus affecting the assessment of its usability.

[0004] In summary, there is an urgent need in the existing technology for a device that can adapt to irregularly shaped springs and enable the irregularly shaped springs to rotate to a predetermined angle. Utility Model Content

[0005] This utility model provides an adapter mechanism, the purpose of which is to adapt to irregularly shaped springs so that the irregularly shaped springs can be driven to rotate and deform.

[0006] To achieve the above objectives, this utility model provides an adapter mechanism, including an adapter comprising a fixedly mounted constraint part and a rotatably mounted rotating part. A non-circular spring is accommodated between the constraint part and the rotating part; the constraint part is provided with a first limiting part for engaging with and limiting a first end of the non-circular spring; the rotating part is provided with a second limiting part for engaging with and limiting a second end of the non-circular spring; the rotation of the rotating part causes the non-circular spring to rotate and deform.

[0007] In this design, the irregularly shaped spring can be housed between the rotating part and the constraining part. Then, a first limiting part engages with the first end of the irregularly shaped spring, and a second limiting part engages with the second module of the irregularly shaped spring. When the rotating part rotates, it causes the irregularly shaped spring to rotate and deform. An adapter achieves compatibility with the irregularly shaped spring, and the rotating part can drive the deformation of the irregularly shaped spring, thus overcoming the shortcomings of existing technologies.

[0008] Preferably, to facilitate the rotation of the rotating part, the adapter in this solution further includes an extension arm. The extension arm is connected to the rotating part, and the rotation of the extension arm drives the rotating part to rotate, causing the irregular spring to rotate and deform. This solution, by connecting the extension arm to the rotating part, allows the rotating part to rotate when the extension arm is subjected to an external force.

[0009] Preferably, since the irregularly shaped spring deforms under force, it is prone to springing away when deformed, which can cause the irregularly shaped spring to detach from the lever arm extender. To solve the above problem, a receiving cavity is constructed between the constraint part and the rotating part in this solution, and the irregularly shaped spring is housed inside the receiving cavity; the rotating part and the constraint part can be separated, so that the receiving cavity can be opened / closed.

[0010] This design uses a receiving cavity to limit and fix the irregularly shaped spring, thus constraining it and preventing it from bouncing away under force. Simultaneously, the rotating part and the constraining part are separable, ensuring that the irregularly shaped spring can be assembled and disassembled.

[0011] Preferably, in order to form a receiving cavity, the constraint part of this embodiment is provided with a first receiving groove, the rotating part is provided with a second receiving groove, and the first receiving groove and the second receiving groove are combined to form the receiving cavity.

[0012] In order to form a receiving cavity, the receiving cavity described in Scheme 2 is disposed on the side wall of the rotating part or the constraining part.

[0013] Preferably, in order to achieve a rotatable connection between the rotating part and the constraining part, the adapter of this solution further includes a rotating shaft, the rotating shaft being connected to the constraining part, the rotating part being mounted on the rotating shaft, and the rotating part rotating about the rotating shaft.

[0014] This design mounts a central shaft onto the constraint part, and then mounts the rotating part onto the central shaft. This achieves a rotatable connection between the constraint part and the rotating part. Furthermore, since the rotating part rotates around the central shaft, its rotation is more stable.

[0015] Preferably, in order to fix the constraint part and allow the rotating part to rotate, the rotating part in this solution is rotatably mounted on the rotating shaft, and the rotating shaft is fixedly connected to the constraint part.

[0016] The rotating shaft and the constraint part described in this solution are integrally formed.

[0017] Preferably, to prevent displacement of the irregularly shaped spring, this solution also includes a frame, on which the adapter is mounted, and the frame is used to fix the adapter. This solution uses a frame to fix the adapter, and the adapter is then fitted with the irregularly shaped spring, ensuring that the irregularly shaped spring will not shift.

[0018] To measure the torque of irregularly shaped springs, a second aspect of this utility model discloses a torque measuring device, including the aforementioned adapter mechanism.

[0019] Preferably, it further includes an angle detector, a pressure detector, and a lifter; the pressure detector is installed on the lifter, the pressure detector is in contact with the adapter mechanism, and the lifter is used to drive the pressure detector to move vertically up and down, so that the adapter mechanism rotates.

[0020] This solution uses an adapter mechanism to fit and install with a shaped spring. When the extension arm in the adapter mechanism rotates, it causes the shaped spring to rotate and deform. When the shaped spring is in a deformed state, the extension arm is in an inclined state. At this time, the pressure is detected by a pressure detector, and the rotation angle of the extension arm from the horizontal plane is detected by an angle detector. Then, combined with the horizontal distance from the center of the shaped spring to the contact point between the extension arm and the pressure detector, the torque data at the corresponding angle can be obtained through the torque calculation formula.

[0021] Preferably, since the extension arm can rotate, in order to ensure that the distance between the contact point between the pressure detector and the extension arm and the center of the irregular spring remains unchanged during the rotation of the extension arm, the pressure detector is preferably equipped with a measuring head, and the measuring head is in contact with the adapter mechanism.

[0022] The beneficial effects of this utility model are as follows: In this solution, the irregularly shaped spring can be accommodated between the rotating part and the constraining part. Then, the first limiting part cooperates with the first end of the irregularly shaped spring, and the second limiting part cooperates with the second module of the irregularly shaped spring. When the rotating part rotates, it drives the irregularly shaped spring to rotate and deform. The adapter achieves the adaptation with the irregularly shaped spring, and the rotating part can drive the irregularly shaped spring to deform, thus solving the shortcomings of the prior art.

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of the embodiments clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0035] Example 1 The basics are as follows: Figure 1 As shown, an adapter mechanism is used to mate with and install the irregularly shaped spring 3, causing the irregularly shaped spring 3 to rotate to a predetermined angle. The irregularly shaped spring 3 deforms during rotation. The irregularly shaped spring 3 is arc-shaped, with its two ends being a first end and a second end, respectively. The irregularly shaped spring 3 is as follows... Figure 8 As shown.

[0036] like Figure 1 As shown, the adapter mechanism specifically includes an adapter 1 and a rack 2. The adapter 1 is mounted on the rack 2 and is fixed by the rack 2.

[0037] like Figure 2 As shown, adapter 1 specifically includes a constraint part 11, a rotating part 12, and an extension arm 13. The constraint part 11 is mounted on the frame 2 and cannot rotate or slide. Figure 3As shown, the constraint part 11 can be disc-shaped or gear-shaped, but gear-shaped is more preferred. A rotating shaft 111 is fixedly mounted on the constraint part 11. In practice, it is preferable that the rotating shaft 111 and the constraint part 11 are integrally formed, or the rotating shaft 111 can be mounted to the constraint part 11 by setting fasteners or welding. The rotating shaft 111 is cylindrical, and a rotating part 12 is sleeved on the rotating shaft 111, and the rotating part 12 can rotate around the center of the rotating shaft 111. In practice, a circular mounting hole 121 is constructed on the rotating part 12, and the mounting hole 121 is sleeved on the rotating shaft 111, allowing the rotating part 12 to rotate around the mounting hole 121 as the center. To prevent the rotating part 12 from disengaging from the rotating shaft 111, an annular groove 111a is provided on the rotating shaft 111, and a retaining ring is detachably installed in the annular groove 111a. The retaining ring abuts against the rotating part 12, preventing the rotating part 12 from disengaging from the rotating shaft 111. Of course, when it is necessary to separate the rotating part 12 from the restraining part 11, simply remove the retaining ring; the rotating part 12 will no longer be restricted, and the rotating part 12 can be separated from the restraining part 11. Figure 5 and Figure 6 As shown, the rotating part 12 can also be disc-shaped or gear-shaped, but is more preferably gear-shaped. The gear-shaped rotating part 12 is detachably connected to the extension arm 13. In practice, the extension arm 13 is configured to include a rod part 132 and a ring part 131, the ring part 131 being circular or rectangular, and the rotating part 12 being housed in the inner ring of the ring part 131. A threaded hole is also formed on the ring part 131, and a screw 131a is housed inside the threaded hole. When the screw 131a rotates in the forward direction, it can be inserted into the gear-shaped rotating part 12, connecting the ring part 131 and the rotating part 12; when the screw 131a rotates in the reverse direction, it can be withdrawn from the gear-shaped rotating part 12, separating the ring part 131 and the rotating part 12. The rod portion 132 is connected to the ring portion 131. The rod portion 132 and the ring portion 131 can be integrally formed, or they can be connected by welding or by fasteners. In order for the rotating portion 12 to drive the irregular spring 3 to rotate and deform, a first limiting portion 112 is provided on the side of the constraint portion 11. The first limiting portion 112 can be a block-shaped protrusion, a rod-shaped protrusion, or a protrusion of other shapes. A second limiting portion 122 is provided on the side of the rotating portion 12. The second limiting portion 122 can also be a block-shaped protrusion, a rod-shaped protrusion, or a protrusion of other shapes. The first end of the irregular spring 3 can abut against the first limiting portion 112 and the second end of the irregular spring 3 can abut against the second limiting portion 122. Therefore, when the rotating portion 12 rotates, the second limiting portion 122 pushes the second end of the irregular spring 3, and the irregular spring 3 rotates and deforms.

[0038] It should be noted that in this embodiment, the protruding structure abuts against the end of the irregular spring 3. However, in some other embodiments, the end of the irregular spring 3 can also be connected to the rotating part 12 and the restraining part 11 by other methods in the prior art. For example, it can be fixedly connected by gluing or by configuring a clamp.

[0039] It should be noted that, in this embodiment, the rotating shaft 111 is preferably fixedly connected to the constraint part 11, while the rotating part 12 is rotatably mounted to the rotating shaft 111. However, in some other embodiments, the rotating shaft 111 and the rotating part 12 can also be fixedly connected, while the rotating shaft 111 and the constraint part 11 are rotatably connected. The rotating shaft 111 and the constraint part 11 can adopt a rotatable connection method in the prior art. For example, a circular hole is provided on the constraint part 11, and the rotating shaft 111 is inserted into the circular hole. At the same time, a limiting structure is provided on the rotating shaft 111, so that the rotating shaft 111 and the constraint part 11 are rotatably connected without separating.

[0040] When the irregularly shaped spring 3 is located between the restraining part 11 and the rotating part 12, in order to restrain the irregularly shaped spring 3 and prevent it from flying off, as follows: Figure 7 As shown, in this embodiment, a receiving cavity is provided in the constraint part 11 and the rotating part 12. The receiving cavity is preferably an annular cavity, and the diameter of the receiving cavity is slightly larger than the diameter of the irregular spring 3. The irregular spring 3 is accommodated inside the receiving cavity. When the irregular spring 3 is accommodated inside the receiving cavity, the irregular spring 3 is limited by the inner wall of the receiving cavity, thereby solving the problem of the irregular spring 3 flying away. In order to construct the receiving cavity, this embodiment preferably has a first receiving groove 113 constructed on the side of the rotating part 12 and a second receiving groove 123 constructed on the side of the constraint part 11. When the rotating part 12 and the constraint part 11 cooperate with each other, the first receiving groove 113 and the second receiving groove 123 are engaged with each other, thereby forming the receiving cavity. When the rotating part 12 and the constraint part 11 are separated, the receiving cavity can be opened.

[0041] It should be noted that: This embodiment introduces a method of constructing a receiving cavity, but in some other embodiments, the receiving cavity may be constructed only on the side of the constraint part 11 or the rotating part 12, and then the receiving cavity may be closed by fitting the constraint part 11 and the rotating part 12 together.

[0042] To keep adapter 1 in a fixed position, frame 2 includes base 21, vertical rod 22, and horizontal shaft 23. Base 21 is a rectangular platform, and a leveling nut is provided at the bottom of base 21. The bottom of vertical rod 22 is fixedly mounted on base 21; in practice, the bottom of vertical rod 22 can be welded to base 21. The top of vertical rod 22 is then fixedly connected to horizontal shaft 23, with horizontal shaft 23 in a horizontal installation state and vertical rod 22 in a vertical state. Horizontal shaft 23 and vertical rod 22 can be fixedly welded or connected by fasteners. To adapt to horizontal shaft 23, a mating hole is provided in the middle of the constraint part 11 in adapter 1, which extends through the entire rotating shaft 111. Horizontal shaft 23 can be inserted into the mating hole, thereby allowing adapter 1 to be detachably installed onto horizontal shaft 23. To secure adapter 1 to the horizontal shaft 23, the outer surface of the horizontal shaft 23 is provided with external threads. A limiting ring 231 with a threaded hole is also mounted on the horizontal shaft 23, and the limiting ring 231 can be a nut. The limiting ring 231 is threaded onto the horizontal shaft 23, holding adapter 1 in place and preventing it from separating from the frame 2. To further prevent adapter 1 from moving on the horizontal shaft 23, a fixing ring is also provided. The fixing ring and the limiting ring 231 are located on opposite sides of adapter 1, thus limiting the left and right movement of adapter 1 and solving the problem of adapter 1 moving.

[0043] The following detailed description illustrates the specific implementation method: When the irregularly shaped spring 3 needs to rotate and deform, it is assembled into the receiving cavity between the rotating part 12 and the restraining part 11. The first end of the irregularly shaped spring 3 abuts against the first limiting part 112, and the second end of the irregularly shaped spring 3 abuts against the second limiting part 122. Then, when the extending arm 13 rotates, because the first end of the irregularly shaped spring 3 abuts against the first limiting part 112, the first end of the irregularly shaped spring 3 is fixed, and the second end of the irregularly shaped spring 3 is driven by the second limiting part 122, causing the irregularly shaped spring 3 to rotate and deform.

[0044] Example 2 This embodiment provides a torque measuring device, such as... Figure 9 As shown, it includes the adapter mechanism of Embodiment 1, pressure detector 4, angle detector 5, and lifter 6.

[0045] The angle detector 5 can be a slope meter or other angle detection device. The angle detector 5 is fixedly installed on the extension arm 13. When the extension arm 13 tilts, the angle detector 5 can detect the rotation angle of the extension arm 13 from the horizontal plane.

[0046] The pressure detector 4 is fixedly installed on the top of the lifting device 6. The lifting structure can be a conventional lifting device 6, such as a lifting platform. The lifting device 6 is fixedly mounted on the base 21 of the frame 2, and its position is fixed. The pressure detector 4 can be a pressure sensor or other pressure detection device.

[0047] The pressure detector 4 contacts the bottom of the extension arm 13. When the lifting device 6 drives the pressure detector 4 to rise, the pressure detector 4 pushes the extension arm 13 to rotate, causing the irregular spring 3 to rotate and deform. The pressure detector 4 is also equipped with a measuring head that contacts the bottom of the extension arm 13. The measuring head is V-shaped, ensuring that the contact position between the pressure detector 4 and the extension arm 13 is a line contact.

[0048] It should be noted that in this embodiment, the rotation of the extension arm 13 is powered by the lifting of the elevator 6. However, in some other embodiments, the extension arm 13 can be directly driven to rotate by external force, and then the elevator 6 can raise the pressure detector 4 to a position where it contacts the extension arm 13.

[0049] The following detailed description illustrates the specific implementation method: When it is necessary to detect the torque data of the irregularly shaped spring 3 at a specific angle, the irregularly shaped spring 3 is first installed between the rotating part 12 and the constraining part 11. When the irregularly shaped spring 3 is located between the rotating part 12 and the constraining part 11, the first end of the irregularly shaped spring 3 is fixed by the constraining part 11, and the second end of the irregularly shaped spring 3 can rotate with the rotating part 12. Then, the lifting device 6 pushes the pressure detector 4 to move vertically upward, thereby causing the extension arm 13 to rotate. During the rotation of the extension arm 13, the rotation angle of the extension arm 13 is detected in real time by the angle detector 5. If the predetermined angle is reached, the lifting device 6 stops rising, and the extension arm 13 stops rotating.

[0050] At this point, the corresponding torque is calculated using the torque calculation formula, which is: Where F1 is the pressure data from pressure detector 4, θ is the rotation data detected by angle detector 5, and S is the horizontal distance between the center of the irregular spring 3 and the contact point between pressure detector 4 and extension arm 13, as shown below. Figure 10 As shown.

[0051] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
