Description

Technical Field

[0001] The utility model belongs to the technical field of detection jigs, and in particular relates to a precision electronic spring elastic force detection jig. Background Art

[0002] An electronic spring is a new type of spring structure based on electronic technology. It uses electronic components and circuits to achieve a similar spring effect. A test fixture is a fixture used to test, measure, or inspect workpieces. Test fixtures typically provide precise positioning and measurement capabilities to ensure that workpieces meet specifications and requirements.

[0003] Traditional electronic springs test springs by stretching and compressing them. During the test, excessive or insufficient force can easily cause spring deformation, making it impossible to precisely control the spring's stretching and compression, resulting in low spring force testing efficiency. To address this issue, we've developed a precision electronic spring force testing fixture to address these issues. Utility Model Content

DETAILED DESCRIPTION

[0027] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] For specific embodiment 1, please refer to Figure 1-6 The utility model is a precision electronic spring force detection fixture, including a support assembly 1, a limit detection assembly 2 and a power drive assembly 4. The support assembly 1 includes a support platform 101, two support rods 102 are fixedly provided on the top of the support platform 101, the limit detection assembly 2 is installed on the top of the support platform 101, the limit detection assembly 2 includes a limit tube 201, the limit tube 201 and the support platform 101 are fixedly connected by a connecting rod 202, a spring 3 is installed inside the limit tube 201, the spring 3 is in contact with the inner wall of the limit tube 201, an annular pressure plate 203 is fixedly provided at one end of the spring 3, and an annular pull plate 204 is fixedly provided at the other end of the spring 3, the annular pressure plate 203 and the annular pull plate 204 are both slidably matched with the inner wall of the limit tube 201, the power drive assembly 4 is installed on the top of the support platform 101, and the power drive assembly 4 includes driving the annular pull plate 204 to move by the power drive assembly 4.

[0029] Specifically, a limiting plate 103 is fixedly provided on the top of the support rod 102, and the limiting plate 103 is fixedly connected to the limiting tube 201. A first sliding opening 106 is opened on the top of the limiting plate 103, and a second sliding opening is opened on the top of the limiting plate 103. A cylinder 104 is installed on the top of the support platform 101, and the cylinder 104 slides with the second sliding opening. A positioning plate 105 is fixedly provided on the top of the support platform 101, and the positioning plate 105 is fixedly connected to the limiting plate 103.

[0030] The specific operation process of this embodiment is as follows: in the initial state, the spring 3 is in a natural state, and the annular pull plate 204 is driven to move by the power drive component 4, so that the spring 3 is stretched along the limit tube 201. When the spring 3 is stretched, the power drive component 4 is stopped to keep the annular pull plate 204 stationary, and then the tension of the spring 3 is recorded, and then the power drive component 4 is controlled to make the annular pull plate 204 move in the opposite direction. At this time, the spring 3 returns to the natural state under the action of its own elastic force, and the stretching rebound force of the spring 3 is recorded at this time. Then, the annular pressure plate 203 is driven to move by the cylinder 104, so that the annular pressure plate 203 generates pressure on the spring 3. When the spring 3 is compressed, the cylinder 104 is stopped from squeezing the annular pressure plate 203. The annular pull plate 204 and the annular pressure plate 203 are then controlled to move away from each other. At this time, the spring 3 returns to its natural state under the action of its own elastic force, and the compression rebound force of the spring 3 is recorded. The operation of the power drive assembly 4 and the cylinder 104 are then controlled simultaneously to make the annular pull plate 204 and the annular pressure plate 203 move toward each other. When the upper and lower ends of the spring 3 are squeezed at the same time, when the squeezing of the spring 3 is completed, the squeezing force of the spring 3 is recorded at this time, and the annular pull plate 204 and the annular pressure plate 203 are then controlled simultaneously to move away from each other. At this time, the spring 3 returns to its natural state under the action of its own elastic force, and the squeezing rebound force of the spring 3 is then recorded. This process can complete the elastic force test of the spring 3.

The spring 3 is sleeved on the side of the guide rod 205, and the guide rod 205 is inside the limit tube 201. When the spring 3 is squeezed, the position of the spring 3 will not be offset.

[0032] Specifically, the output end of the cylinder 104 is fixedly connected to the movable plate 206, and two L-shaped fixing plates 207 are fixedly provided on the top of the movable plate 206.

A pressure sensor 209 is installed on the top of the annular pressure plate 203 (the tension and stretching rebound force of the spring 3 are detected by the pressure sensor 209). The control cylinder 104 drives the movable plate 206 to move downward, and the two L-shaped fixing plates 207 move downward to drive the annular pressure plate 203 to move downward. At this time, the spring 3 is squeezed, and the control cylinder 104 drives the movable plate 206 to move upward. The two L-shaped fixing plates 207 move upward to drive the annular pressure plate 203 to move upward. At this time, the spring 3 can return to its natural state under the action of its own elastic force.

[0033] Furthermore, two guide openings 210 are provided on the side surface of the limiting tube 201, and the two L-shaped fixing plates 207 are slidably fitted with the corresponding guide openings 210.
