Abstract
Description
Technical Field
[0001] This utility model relates to the field of spring manufacturing technology, and more specifically to a device for testing and manufacturing compression spring cores. Background Technology
[0002] Springs are often added to furniture and home furnishings to improve user comfort, such as in sofas, mattresses, and chairs. Springs act as a dynamic cushioning layer to provide support and absorb pressure, effectively relieving the stress experienced by users when in contact with the product.
[0003] In the production process of spring cores, the durability and compressive strength of the springs are the main indicators. If the compressive strength is insufficient, the furniture is prone to collapse or deformation after long-term use, resulting in the scrapping of the furniture. However, in the testing process, multiple springs are often randomly selected and placed on the testing device one by one for testing. The testing of each spring part requires a lot of time, which will affect the spring testing efficiency. Utility Model Content
[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by resolving the issue that when multiple springs are extracted and tested one by one, the time required for each test is relatively long, which in turn affects the efficiency of spring testing, since the test is for durability or compressive strength.
[0005] To achieve the above objectives, this utility model can be implemented through the following technical solution: a production and testing device for compression spring cores, comprising an elastic element, and further comprising:
[0006] A base plate, on which a reciprocating transmission unit is provided;
[0007] A clamping seat is arranged in a linear array on the base plate. A tension detector is provided on the clamping seat, and a second hook is provided at the output end of the tension detector.
[0008] The clamping seat has a slider that cooperates with the reciprocating transmission unit. The slider has a first hook, and the elastic element is disposed between the first hook and the second hook.
[0009] In this embodiment of the utility model, the reciprocating transmission unit includes a motor and a turntable disposed at the output end of the motor, and a support block that slides on the base plate is disposed at the eccentric part of the turntable;
[0010] A cylinder is provided on the slider, and a linkage is provided at the output end of the cylinder, which cooperates with the support block.
[0011] In this embodiment of the utility model, a sliding groove is provided on the support block, a fixed inclined block is fixedly connected to one side of the sliding groove, and a triangular block is slidably connected to the other side;
[0012] One end of the linkage is provided with a locking block, and a spring is provided between the locking block and the linkage. The locking block is pulled back by the spring and slides in the slide groove, and abuts against the fixed inclined block or triangular block.
[0013] In this embodiment of the utility model, the linkage includes a sleeve and a support rod extending or retracting from the sleeve, and one end of the sleeve is provided with a collar that is threadedly connected to the support rod.
[0014] In this embodiment of the utility model, mounting holes are linearly arrayed at the eccentric part of the turntable, and a locking rod that engages with the mounting holes is provided on the support block.
[0015] In this embodiment of the utility model, a motor is provided on the base plate, a first bevel gear is provided on the output end of the motor, the turntable has a rotating shaft, and a second bevel gear that meshes with the first bevel gear is provided on the rotating shaft.
[0016] In this embodiment of the utility model, a bending frame is provided on the base plate, and the motor is fixed on the bending frame.
[0017] In this embodiment of the utility model, a guide block is provided on the base plate, and the support block slides on the guide block.
[0018] In this embodiment of the utility model, a V-shaped block is provided on the clamping seat, and the tension detector is fixed on the V-shaped block.
[0019] In this embodiment of the utility model, the clamping seat is provided with a slide rail, and the slider slides on the slide rail.
[0020] Compared with the prior art, the advantages of this application are as follows: During the test, multiple sets of elastic elements are extracted and placed between the first hook and the second hook. The reciprocating transmission unit controls the slider to slide back and forth on the clamping seat to test multiple elastic elements. When the elastic element deforms, the value on the tensile detector will change, thereby allowing multiple sets of elastic elements to be tested at one time, thus improving the testing efficiency of elastic elements.

[0028] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.
[0029] like Figure 1-5 As shown, a compression spring core production and testing device includes an elastic element 3, and further includes:
[0030] Base plate 1, on which a reciprocating transmission unit 4 is provided;
[0031] Clamping seats 2 are arranged in a linear array on the base plate 1, and the linear array is as follows: Figure 1 As shown, multiple sets of clamping seats 2 are evenly arranged from left to right. The more clamping seats 2 there are, the more elastic elements 3 can be detected at one time. A tension detector 27 is provided on the clamping seat 2, and a second hook 26 is provided at the output end of the tension detector 27.
[0032] A slider 21 that cooperates with the reciprocating transmission unit 4 is slidably arranged on the clamping base 2. A first hook 24 is provided on the slider 21, and an elastic element 3 is arranged between the first hook 24 and the second hook 26.
[0033] Specifically, such as Figure 1 and Figure 4As shown, the elastic element 3 can be a helical spring or a serpentine spring. The spring core is assembled from multiple helical springs 411 and serpentine springs 411. After the production of the elastic element 3 is completed, multiple parts can be extracted and assembled onto the first hook 24 and the second hook 26. At the same time, a certain pressure or tension is applied to it through the linkage 22. At this time, the reciprocating transmission unit 4 controls the slider 21 to slide back and forth on the slide rail 25 to detect the elastic element 3 until the elastic element 3 is deformed or damaged. The value on the tension detector 27 will change, and the time required for the damage will be recorded. At the same time, the eccentric position of the support block 41 and the turntable 43 can be adjusted to change the tension or compression force on the elastic element 3, thereby reflecting the durability and compressive strength of the elastic element 3 under different forces, thus improving the accuracy of the detection process. At the same time, the device can detect multiple elastic elements 3 at one time, thereby improving the detection efficiency of the elastic element 3.
[0034] As a further embodiment of this utility model, the reciprocating transmission unit 4 includes a motor 44 and a turntable 43. A support block 41 that slides on the base plate 1 is provided at the eccentric part of the turntable 43. A cylinder 23 is provided on the slider 21. A linkage 22 is provided at the output end of the cylinder 23. The linkage 22 cooperates with the support block 41. The motor 44 controls the turntable 43 to rotate. At this time, the turntable 43 rotates to control the support block 41 to slide on the guide block 11, thereby performing a reciprocating pulling or squeezing test on the elastic member 3.
[0035] As a further embodiment of this utility model, a groove 414 is provided on the support block 41. A fixed inclined block 415 is fixedly connected to one side of the groove 414, and a triangular block 413 is slidably connected to the other side. A locking block 412 is provided at one end of the linkage 22. A spring 411 is provided between the locking block 412 and the linkage 22. The locking block 412 is pulled back by the spring 411 and slides in the groove 414, abutting against the fixed inclined block 415 or the triangular block 413. When the elastic member 3 is fixed on the clamping seat 2, a certain pre-tension force is applied to the elastic member 3. At this time, the locking block 412 slides in the groove 414 under the pull of the spring 411 and fits against the inclined surface of the fixed inclined block, so that the linkage 22 will not detach from the support block 41 during the test. When the elastic member 3 deforms... At this time, the frequency of the value on the tension detector 27 will change, and the motor 44 will be stopped and the cylinder 23 will be started after the electrical signal controls it. At this time, the cylinder 23 pushes the locking block 412 away from the fixed tilting block 415 through the linkage 22 until the locking block 412 contacts the tilting surface of the triangular block 413. This tilting surface is close to the tilting surface on the side of the turntable 43. At this time, the cylinder 23 retracts to drive the locking block 412 and the triangular block 413 to slide in the slide groove 414. At this time, the triangular block 413 is in contact with the fixed tilting block 415, and the locking block 412 slides along the triangular block 413 under the pulling force of the cylinder 23, so that the linkage 22 separates from the support block 41. Then the motor 44 runs to continue to detect the other elastic elements 3, so as to accurately record the maximum time that each elastic element 3 can withstand.
[0036] As a further embodiment of this utility model, the linkage 22 includes a sleeve 221 and a support rod 223 extending or retracting from the sleeve 221. One end of the sleeve 221 is provided with a collar 222 threadedly connected to the support rod 223. The collar 222 is rotatably connected to the end of the sleeve 221. When the collar 222 is rotated, the support rod 223 gradually extends or retracts into the sleeve 221 under the thread drive of the collar 222, so as to adjust the tension or compression force on the elastic member 3.
[0037] As a further embodiment of this utility model, mounting holes 431 are linearly arrayed at the eccentric part of the turntable 43, and a locking rod 42 is provided on the support block 41 to engage with the mounting holes 431. The locking rod 42 on the support block 41 is threadedly connected to the mounting holes 431. The closer the fixed mounting hole 431 is to the central axis of the turntable 43, the faster the pushing frequency of the slider 21. Similarly, the farther the fixed mounting hole 431 is from the central axis of the turntable 43, the greater the pushing amplitude of the slider 21.
[0038] As a further embodiment of this utility model, a bending frame is provided on the base plate 1, and the motor 44 is fixed on the bending frame. The bending frame is fixed to the base plate 1 by bolts and serves to support the motor 44, thereby improving the output stability of the motor 44.
[0039] As a further embodiment of this utility model, a motor 44 is provided on the base plate 1, and a first bevel gear 45 is provided on the output end of the motor 44. The turntable 43 has a rotating shaft, and a second bevel gear 46 that meshes with the first bevel gear 45 is provided on the rotating shaft. The model of the motor 44 may be: MHMF042L1U4-1116. The motor 44 is used as a power source to control the rotation of the first bevel gear 45. Since the first bevel gear 45 meshes with the second bevel gear 46, the rotation of the turntable 43 is controlled. At the same time, the first bevel gear 45 and the second bevel gear 46 adjust the installation direction of the motor 44.
[0040] As a further embodiment of this utility model, a guide block 11 is provided on the base plate 1, and a support block 41 slides on the guide block 11. The guide block 11 is located on both sides of the turntable 43, and the guide block 11 is higher than the turntable 43 to avoid the support block 41 from colliding or rubbing against the turntable 43 during the sliding process. At the same time, the guide block 11 restricts the sliding direction of the support block 41.
[0041] As a further embodiment of this utility model, a V-block 28 is provided on the clamping base 2, and the tension detector 27 is fixed on the V-block 28. The V-block 28 is fixed on the clamping base 2 by bolts. The tension detector 27 is fixed by the V-block 28 to improve the detection stability of the elastic element 3.
[0042] As a further embodiment of this utility model, the clamping seat 2 is provided with a slide rail 25, and the slider 21 slides on the slide rail 25. The slide rail 25 plays a guiding and supporting role, so as to guide the slider 21 to slide along the slide rail 25 to approach or move away from the tension detector 27, to squeeze or stretch the elastic member 3, thereby improving the detection accuracy of the elastic member 3.
[0043] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.
