Description

Technical Field

[0001] This utility model relates to the field of spring production, and in particular to a spring production apparatus. Background Technology

[0002] A spring is a mechanical part used for working: a spring testing machine is a testing instrument specifically designed for sofa spring frames and spring packs.

[0003] For example, the patent entitled "A Spring Force Testing Device for Spring Production" (patent application number: CN202320358971.8) discloses a spring force testing device for spring production. The new spring force testing device changes the traditional phenomenon of not limiting the spring by using a limiting plate for limiting treatment. During the test, the spring will not deviate and will not affect the quality of the spring force test. However, it can only test the entire spring and cannot test parts of the spring as needed, so the testing range is limited.

[0004] Therefore, it is necessary to propose a spring production device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a spring production device that can only test the entire spring and cannot test only the parts of the spring as needed, thus limiting the testing range.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a spring production device, including a base, a vertical plate fixed on one side of the base, a support plate slidably installed on one side of the top of the base along the length direction, a fixing rod fixed on the top of the support plate, and a test spring sleeved on the fixing rod;

[0007] A pressure plate is raised and lowered above the fixed rod. An auxiliary rod is provided on one side of the fixed rod. A limit plate is slidably installed on the auxiliary rod. One side of the limit plate is engaged in the test spring, and the other side of the limit plate is inserted into the upright plate.

[0008] Preferably, the pressure plate has through holes for the fixing rod and auxiliary rod to pass through, and a pressure sensor is provided at the bottom end of the pressure plate;

[0009] A displacement sensor is embedded in the top of the support plate.

[0010] Preferably, the upright plate has multiple insertion holes along the height direction, and a plug is fixed on one side of the limiting plate, the plug being inserted into the corresponding insertion hole.

[0011] Preferably, a top plate and a connecting plate are fixed to the top and bottom ends of the side of the upright plate away from the base, respectively, and a threaded rod is rotatably connected between the top plate and the connecting plate;

[0012] The upright plate has a sliding groove along its height direction, and one side of the pressure plate passes through the sliding groove and is threaded to the outside of the threaded rod.

[0013] A drive motor is fixed to the bottom of the connecting plate, and the drive shaft of the drive motor is connected to the bottom of the threaded rod.

[0014] Preferably, a fixing screw is provided on the outer side of the limiting plate, and one end of the fixing screw is pressed against the outer side of the auxiliary rod.

[0015] Preferably, auxiliary plates are fixed on both sides of the support plate, and corresponding connection holes are opened on the two auxiliary plates and the base, with a pin inserted between the two corresponding connection holes.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] By adding an auxiliary rod, the stability of the pressure plate during the lifting and lowering process can be increased. At the same time, after the pressure plate moves downward, the auxiliary rod and the fixed rod can slide out from the through hole on the pressure plate, and the test spring will be squeezed by the pressure plate. The pressure sensor can detect the pressure, and the displacement sensor can measure the distance between the pressure plate and the base, thereby determining the length of the squeezed test spring.

[0018] 2. In the actual operation of this utility model, a limiting plate can be sleeved on the outside of the auxiliary rod, so that one side of the limiting plate can be inserted into the fixed rod, thereby limiting the test spring at any height position. When the pressure plate is pressed down, only the test spring part between the limiting plate and the pressure plate can be squeezed for testing, thereby improving the test range. As needed, the limiting plate can be inserted at any height, and the test spring part at any height can be tested. Attached Figure Description

[0023] This utility model provides, for example Figs. 1-3 The spring production device shown includes a base 1, which is the basic structure of the entire device. The base 1 is rectangular in shape, made of high-strength steel, and has sufficient load-bearing capacity and stability.

[0024] A vertical plate 2 is fixed to one side of the base 1, and a support plate 10 is slidably installed on one side of the top of the base 1 along the length direction. A fixing rod 8 is fixed to the top of the support plate 10, and a test spring is sleeved on the fixing rod 8. The main function of the vertical plate 2 is to provide support and guidance for the device.

[0025] A pressure plate 18 is lifted and lowered above the fixed rod 8. A top plate 6 and a connecting plate 3 are fixed at the top and bottom of the side of the upright plate 2 away from the base 1, and a threaded rod 5 is rotatably connected between the top plate 6 and the connecting plate 3.

[0026] The upright plate 2 has a sliding groove 7 along the height direction. One side of the pressure plate 18 passes through the sliding groove 7 and is threaded to the outside of the threaded rod 5. The bottom end of the connecting plate 3 is fixed with a drive motor 4, and the drive shaft of the drive motor 4 is connected to the bottom end of the threaded rod 5.

[0027] The drive motor 4 can be a servo motor to complete forward and reverse rotation, thereby driving the threaded rod 5 to rotate and realize the up and down movement of the pressure plate 18.

[0028] In the actual operation of this utility model, since the support plate 10 can slide on the base 1, the test spring can be easily sleeved on the fixed rod 8 through the support plate 10, so that the fixed rod 8 is not affected by the pressure plate 18. After the sleeve is completed, the support plate 10 can be pushed back again so that the top of the fixed rod 8 corresponds with the pressure plate 18, which facilitates the subsequent pressing work.

[0029] An auxiliary rod 19 is provided on one side of the fixed rod 8. The auxiliary rod 19 is fixed to the top of the support plate 10. A through hole is provided on the pressure plate 18 for the fixed rod 8 and the auxiliary rod 19 to pass through. A pressure sensor 17 is provided at the bottom of the pressure plate 18. A displacement sensor 9 is embedded in the top of the support plate 10.

[0030] By adding the auxiliary rod 19, the stability of the pressure plate 18 during the lifting and lowering process can be increased. At the same time, after the pressure plate 18 moves downward, the auxiliary rod 19 and the fixed rod 8 can slide out from the through hole on the pressure plate 18, and the test spring will be squeezed by the pressure plate 18. The pressure sensor 17 can detect the pressure, and the displacement sensor 9 can test the distance between the pressure plate 18 and the base 1, thereby determining the length of the squeezed test spring.

[0031] A limiting plate 16 is slidably installed on the auxiliary rod 19. One side of the limiting plate 16 is engaged in the test spring, and the other side of the limiting plate 16 is inserted into the upright plate 2.

[0032] The upright plate 2 has multiple insertion holes 13 along the height direction. A plug 14 is fixed on one side of the limiting plate 16. The plug 14 is inserted into the corresponding insertion hole 13. A fixing screw 15 is provided on the outside of the limiting plate 16. One end of the fixing screw 15 is pressed against the outside of the auxiliary rod 19.

[0033] In the actual operation of this utility model, a limiting plate 16 can be sleeved on the outside of the auxiliary rod 19, so that one side of the limiting plate 16 can be inserted into the fixed rod 8, thereby limiting the test spring at any height position. When the pressure plate 18 is pressed down, only the test spring part between the limiting plate 16 and the pressure plate 18 can be squeezed for testing, thus improving the completeness of the test.

[0034] Auxiliary plates 11 are fixed on both sides of the support plate 10. The two auxiliary plates 11 and the base 1 have corresponding connection holes. A pin 12 is inserted between the two corresponding connection holes to fix the support plate 10 to the base 1.
