Description

Technical Field

[0001] This utility model relates to the field of spring testing technology, specifically a spring pressure testing device. Background Technology

[0002] In fields such as machinery manufacturing, automotive industry, and electronic equipment, springs, as core elastic components, directly determine the operating accuracy and service life of equipment based on their pressure parameters.

[0003] A spring pressure testing device typically consists of a loading system, a sensing module, a data processing unit, a positioning fixture, and a human-machine interface. Its working principle is as follows: the spring is placed on the positioning fixture, the loading system applies pressure to the spring according to a preset program, the sensing module simultaneously collects force and displacement signals, and the data processing unit converts the signals into digital parameters and compares them with standard values ​​to determine whether the spring is qualified. In terms of operation, the operator selects the testing program corresponding to the spring model, places the spring, and starts the equipment; the system automatically completes the loading, testing, and unloading process.

[0004] However, the above-mentioned equipment has obvious shortcomings in use. Traditional spring pressure testing devices are mostly single-station designs, which can only test a single spring at a time. When replacing a spring, the old spring must be removed manually, the new spring must be placed and realigned. Batch testing is time-consuming and extremely inefficient. In view of this, we propose a spring pressure testing device. Utility Model Content

[0005] The purpose of this invention is to provide a spring pressure detection device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A spring pressure detection device includes a base plate, on which a mounting box is fixedly mounted, and on which a bracket is fixedly mounted. An alternating assembly is disposed on the mounting box, the alternating assembly comprising:

[0008] A hydraulic device is fixedly mounted on the bracket. A pressure sensor is fixedly mounted on the piston end of the hydraulic device. A contact head is fixedly mounted on the contact end of the pressure sensor. A contact plate is slidably mounted on the piston end of the hydraulic device.

[0009] The motor is fixedly mounted on the mounting box. A threaded rod is fixedly mounted on the output end of the motor. A slider is threaded onto the threaded rod. A straight groove is opened on the mounting box. A sliding plate is fixedly mounted on the slider. A slide rail is fixedly mounted on the mounting box. One end of a spring rod is fixedly mounted on the bracket.

[0010] An arc-shaped positioning plate is fixedly installed at the other end of the spring rod. An airfoil plate is fixedly installed on the arc-shaped positioning plate. A circular roller is rotatably installed on the airfoil plate. One end of a limit rod is fixedly installed on the arc-shaped positioning plate. A limit circular plate is fixedly installed at the other end of the limit rod. A limit hole is opened on the bracket.

[0011] In a further embodiment, a placement cylinder is fixedly installed on the slide plate, a detection spring is placed inside the placement cylinder, the slide plate is slidably installed on the slide rail via a sliding member, and the slider slides inside the straight groove.

[0012] In a further embodiment, multiple sets of the contact head, slider, slide rail, spring rod, arc-shaped positioning plate, airfoil plate, circular roller, limiting rod, limiting circular plate, limiting hole, and placement cylinder are provided.

[0013] In a further embodiment, the placement cylinder is positioned directly below the hydraulic device, pressure sensor, contact head, and contact plate, and is positioned between multiple sets of arc-shaped positioning plates.

[0014] In a further embodiment, the mounting box is provided with an auxiliary component, which includes a limiting groove. The sliding plate has a limiting groove, a limiting block is fixedly mounted on the mounting box, a mounting plate is fixedly mounted on the slider, one end of a spring damping rod is fixedly mounted on the mounting plate, and a rubber head is fixedly mounted on the other end of the spring damping rod.

[0015] In a further embodiment, multiple sets of the limiting groove, limiting block, mounting plate, spring damping rod, and rubber head are provided.

[0016] In a further embodiment, the mounting plate, spring damping rod, and rubber head are disposed inside the mounting box, and the limiting block slides inside the limiting groove.

[0017] Compared with the prior art, the present invention provides a spring pressure detection device, which has the following advantages:

[0018] 1. This spring pressure testing device, in order to be suitable for batch spring pressure performance testing, is equipped with an alternating component. This component, in conjunction with a hydraulic device, pushes the pressure sensor and contact head downward, so that the contact plate contacts the test spring inside the placement cylinder. The pressure sensor collects pressure data in real time, and the motor drives the threaded rod to rotate, causing the slider to move the slide plate along the slide rail, realizing the alternating switching of multiple placement cylinders, improving testing efficiency. At the same time, the arc-shaped positioning plate fits against the side of the placement cylinder under the action of the spring rod, the round roller on the wing plate reduces friction, and the limiting rod passes through the limiting hole to limit the offset.

[0019] 2. To improve the stability of continuous operation of the spring pressure detection device, an auxiliary component is provided. This component works with the limiting block to slide within the limiting groove, providing rigid guidance for the movement of the slide plate and avoiding spring alignment deviation caused by slider offset. When the slide plate switches to the detection station, the spring damping rod pushes the rubber head to contact the inner wall of the mounting box to absorb impact vibration and ensure the stability of the pressure sensor data. Multiple symmetrically distributed auxiliary units ensure uniform force distribution and prevent deformation of the slide plate due to long-term use. Attached Figure Description

[0035] A spring pressure detection device includes a base plate 1, a mounting box 2 fixedly mounted on the base plate 1, and a bracket 3 fixedly mounted on the mounting box 2.

[0036] In one embodiment of this utility model, an alternating component 4 is provided on the mounting box 2. The alternating component 4 includes a hydraulic device 41. The hydraulic device 41 is fixedly mounted on the bracket 3. A pressure sensor 42 is fixedly mounted on the piston end of the hydraulic device 41. A contact head 43 is fixedly mounted on the contact end of the pressure sensor 42. A contact plate 44 is slidably mounted on the piston end of the hydraulic device 41. A motor 45 is fixedly mounted on the mounting box 2. A threaded rod 46 is fixedly mounted on the output end of the motor 45. A slider 47 is threadedly mounted on the threaded rod 46. A straight groove 48 is provided on the mounting box 2. A sliding plate 49 is fixedly mounted on the slider 47. A slide rail 410 is fixedly mounted on the mounting box 2. One end of a spring rod 411 is fixedly mounted on the bracket 3. An arc-shaped positioning plate 412 is fixedly mounted on the other end of the spring rod 411. An airfoil plate 413 is fixedly mounted on the arc-shaped positioning plate 412. A circular roller 414 is rotatably mounted on the bracket 3. One end of a limit rod 415 is fixedly mounted on the arc-shaped positioning plate 412, and a limit circular plate 416 is fixedly mounted on the other end of the limit rod 415. A limit hole 417 is opened on the bracket 3. A placement cylinder 418 is fixedly mounted on the slide plate 49. A detection spring 6 is placed inside the placement cylinder 418. The slide plate 49 is slidably mounted on the slide rail 410 through a sliding member. The slider 47 slides inside the straight groove 48. Multiple sets of contact head 43, slider 47, slide rail 410, spring rod 411, arc-shaped positioning plate 412, wing plate 413, circular roller 414, limit rod 415, limit circular plate 416, limit hole 417 and placement cylinder 418 are provided. The placement cylinder 418 is located directly below the hydraulic device 41, pressure sensor 42, contact head 43 and contact plate 44. The placement cylinder 418 is located between multiple sets of arc-shaped positioning plates 412.

[0037] In this embodiment, the detection spring 6 to be tested is placed into the placement cylinder 418 on the slide plate 49. The motor 45 is started, and the output end of the motor 45 drives the threaded rod 46 to rotate, causing the slider 47, which is threaded onto the threaded rod 46, to slide along the straight groove 48 on the mounting box 2. This, in turn, causes the slide plate 49 on the slider 47 to slide along the slide rail 410, realizing the alternating switching of multiple sets of placement cylinders 418. The placement cylinder 418 containing the detection spring 6 is then transported to the testing station. At this time, the spring rod 411 on the bracket 3 pushes the arc-shaped positioning plate 412 to fit against the side of the placement cylinder 418, positioning the placement cylinder 418. The wing plate 413 on the arc-shaped positioning plate 412 and The roller 414 reduces friction during the movement of the placement cylinder 418. The limiting rod 415 on the arc-shaped positioning plate 412 passes through the limiting hole 417 on the bracket 3. The limiting circular plate 416 prevents the limiting rod 415 from falling off and further limits the offset of the arc-shaped positioning plate 412. Subsequently, the hydraulic device 41 on the bracket 3 is activated, and its piston end pushes the pressure sensor 42 and the contact head 43 to move down. The contact plate 44 moves down and contacts the detection spring 6 in the placement cylinder 418, applying pressure to the detection spring 6. The pressure sensor 42 collects pressure data in real time to complete the pressure performance test of the detection spring 6. Multiple sets of components work together to achieve batch testing and improve testing efficiency.

The mounting plates 53, spring damping rods 54 and rubber heads 55 are located inside the mounting box 2. The limiting block 52 slides inside the limiting groove 51.

[0039] In this embodiment, during the sliding of the slide plate 49 along the slide rail 410, the limiting block 52 on the mounting box 2 slides within the limiting groove 51 on the slide plate 49, providing rigid guidance for the movement of the slide plate 49 and preventing misalignment between the detection spring 6 and the contact plate 44 due to the offset of the slider 47. When the slide plate 49 switches to the detection station, the spring damping rod 54 on the mounting plate 53 on the slider 47 pushes the rubber head 55 to contact the inner wall of the mounting box 2, absorbing the impact vibration generated by the movement of the slide plate 49, ensuring the stability of the data collected by the pressure sensor 42. Multiple sets of symmetrically distributed auxiliary components 5 make the slide plate 49 uniformly stressed, preventing deformation due to long-term use and improving the stability of continuous operation of the equipment.
