Description

Technical Field

[0001] The utility model relates to the technical field of spring production, in particular to a detection device for spring production. Background Art

[0002] Springs are mechanical parts that work by using elasticity. Parts made of elastic materials deform under external forces and return to their original shape after the external forces are removed. They are also called "springs". They are generally made of spring steel. There are many types of springs. According to their shapes, they mainly include helical springs, scroll springs, leaf springs, special-shaped springs, etc. Spring testing is an important part to ensure the quality and performance of springs.

[0003] In the process of spring production, a detection device is needed to detect it. The Chinese utility model patent with the announcement number CN213121035U discloses a detection device for spring production, including a box; the bottom ends of both sides of the box are fixedly connected with a fixing plate, one side of the box is fixedly connected with a console, the upper surface of the box is fixedly connected with a chassis, the upper surface of the chassis is fixedly connected with a limit rod, and both sides of the chassis are fixedly connected with a limit rod. The utility model sets a base, a clamping plate and a position sensor, and places the spring through the fixing rod on the base. At the same time, two clamping plates are used to fix the spring firmly, and a position sensor is used to record the position of the spring. Then, a pressure ring is used to apply pressure to the spring. If the length of the spring is deformed, the position sensor will feed back the data recorded on the spring length to the console, telling the staff that the spring does not meet the qualified standard. By using the press ring and the position sensor to detect the qualified standard of the spring, the accuracy of the detection is improved, and the error is low.

[0004] However, during the use of the utility model, since it can only detect the elastic force of the spring but cannot detect the tensile force of the spring, the staff needs to use additional tools for detection, which affects the detection efficiency and cannot meet the production needs. Therefore, a detection device for spring production is proposed to solve the above-mentioned problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a detection device for spring production, which has the advantage of being easy to detect the tension of the spring. It solves the problem that when testing the spring, only the elastic force of the spring can be detected, but the tension of the spring cannot be detected, which requires the staff to use additional tools for detection, affecting the detection efficiency and failing to meet production needs.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a detection device for spring production, comprising a base and a top plate arranged on the top of the base, two support plates are fixedly connected between the top plate and the base, a lifting platform is arranged at the bottom of the top plate, and a tension detection conversion mechanism extending to the bottom of the lifting platform is arranged inside the lifting platform;

[0007] The tension detection conversion mechanism includes a driving motor fixedly installed inside the lifting platform, a conversion plate is rotatably connected to one side of the lifting platform close to the base, the output shaft of the driving motor is fixedly connected to the conversion plate, two mounting seats are fixedly installed at the bottom of the conversion plate, a tension measuring device is fixedly installed at the bottom of the mounting seat, and a hook is fixedly installed at the bottom of the tension measuring device.

[0008] Furthermore, a movable block extending into the interior of another mounting seat is slidably connected to a side of the other mounting seat close to the base, and a pressure sensor is fixedly installed inside the mounting seat.

[0009] Furthermore, a limit block extending into the interior of the lifting platform is fixedly connected to the top of the conversion plate, and a limit groove matched with the limit block is formed on the lower surface of the lifting platform.

[0010] Furthermore, a placing platform is fixedly connected to the top of the base, a mounting platform is fixedly connected to the top of the placing platform, and a positioning column is fixedly connected to the center position of the top of the mounting platform.

[0011] Furthermore, an extrusion block is slidably connected inside the mounting platform, a return spring is fixedly connected between the extrusion block and the inner wall of the mounting platform, and a fixed clamp block extending to the top of the mounting platform is arranged on the top of the extrusion block.

[0012] Furthermore, a connecting block is fixedly connected between the fixed clamping block and the extrusion block, and a movable groove adapted to the connecting block is provided on the upper surface of the mounting platform.

[0013] Furthermore, the interior of the top plate is rotatably connected to a threaded sleeve extending to the outside thereof, the top of the lifting platform is rotatably connected to a threaded rod penetrating the threaded sleeve, and the threaded rod is threadedly connected to the threaded sleeve.

[0014] Furthermore, a dual-axis motor is fixedly installed on the top of the top plate, a connecting shaft is fixedly connected to the output shaft of the dual-axis motor, a transmission gear is fixedly connected to one end of the connecting shaft away from the dual-axis motor, and a driven gear meshing with the transmission gear is fixedly installed on the outside of the threaded sleeve.

[0015] Compared with the prior art, the utility model provides a detection device for spring production, which has the following beneficial effects:

[0016] 1. The detection device for spring production is provided with a hook and a tension meter. When one end of the spring can be hooked, and then when the lifting platform moves upward, the hook will stretch the spring. At this time, the tension meter can measure the current tension, and then perform a tension test on the spring. By setting a drive motor to drive the conversion plate to rotate, the hook and the movable block can be driven to rotate, which is convenient for the staff to perform two different tests on the spring. The staff does not need to use additional fixed tools to test the spring, thereby improving the detection efficiency.

[0017] 2. The detection device for spring production drives the transmission gear and the driven gear to rotate by setting a dual-axis motor, and then drives the threaded sleeve to rotate by the driven gear, so that the threaded sleeve can drive the threaded rod to rotate and move up and down, thereby facilitating the lifting and lowering of the lifting platform. It can meet the two modes of pressure detection and tension detection, and solves the problem that when testing the spring, only the elastic force of the spring can be detected, and the tension of the spring cannot be detected, which requires the staff to use additional tools for detection, affecting the detection efficiency and failing to meet the production needs.
