In order to overcome the defects of the prior art, the utility model aims to solve the technical problem that a spring tension and compression testing machine capable of accurately testing a plurality of springs on one testing machine is provided.
In order to solve the technical problem, the utility model discloses a technical scheme be:
the utility model provides a spring pressure fatigue testing machine, includes workstation and elevating platform, the workstation is equipped with down the pressure disk, the elevating platform is equipped with the pressure disk, the pressure disk is equipped with pressure sensor down, still includes two lifter and circular protection section of thick bamboo, the diameter of circular protection section of thick bamboo equals the spring diameter of examination of awaiting measuring, circular protection section of thick bamboo is vertically located between pressure disk and the lower pressure disk, go up the center between pressure disk and the lower pressure disk and align with the centre of a circle of circular protection section of thick bamboo, two the lifter is vertically located the both sides of circular protection section of thick bamboo and is connected with the lateral wall of circular protection section of thick bamboo.
Furthermore, the circular protective cylinder comprises a plurality of cylinder parts with different diameters, a convex edge is arranged at one end of each cylinder part, and the cylinder parts are mutually sleeved and fixedly formed into the circular protective cylinder through the convex edges.
Furthermore, the inner diameter of the larger cylinder in the two adjacent cylinders which are sleeved with each other is equal to the outer diameter of the smaller cylinder.
Furthermore, the side wall of the circular protective cylinder is provided with two vertically arranged connectors, and the circular protective cylinder is detachably sleeved on the top end of the lifting rod through the connectors.
Further, the upper platen is provided with a sensor configured to detect a distance between the upper platen and the circular shield cylinder.
The beneficial effects of the utility model reside in that:
by adopting the technical scheme provided by the utility model, the distance from the circular protective cylinder to the lower press plate is adjusted according to the springs to be tested with different specifications during testing, if the length of the spring to be tested is longer, the height of the circular protective cylinder is increased by the lifting rod, so that the distance from the circular protective cylinder to the lower press plate is increased; when the length of the spring to be tested is short, the height of the circular protective cylinder is reduced by the lifting rod, the distance from the circular protective cylinder to the lower pressing disc is reduced, the springs to be tested in different specifications can be tested, and the applicability is wide. Simultaneously, the spring that awaits measuring compresses tightly in a circular protection section of thick bamboo under the drive of last pressure disk, and the inner wall of a circular protection section of thick bamboo plays limiting displacement, prevents that the spring that awaits measuring from askewly falling, guarantees the accuracy of spring test.

Detailed Description
In order to explain the technical content, the objects and the effects of the present invention in detail, the following description is made with reference to the accompanying drawings in combination with the embodiments.
Referring to fig. 1, a spring pressure fatigue testing machine comprises a spring to be tested, a workbench 1 and a lifting platform 2. The workbench 1 is provided with a lower pressure plate 3, the lifting platform 2 is provided with an upper pressure plate 4, and the lower pressure plate 3 is provided with a pressure sensor. This technical scheme still includes two lifter 5 and circular protection section of thick bamboo 6, and the diameter of circular protection section of thick bamboo 6 equals the diameter of the spring that awaits measuring, and circular protection section of thick bamboo 6 is located vertically between pressure disk 4 and the lower pressure dish 3, goes up the center between pressure disk 4 and the lower pressure dish 3 and aligns with the centre of a circle of circular protection section of thick bamboo 6, and two lifter 5 are located the both sides of circular protection section of thick bamboo 6 vertically and are connected with the lateral wall of circular protection section of thick bamboo 6.
The use principle is as follows:
when in test, the distance from the circular protective cylinder 6 to the lower press plate 3 is adjusted according to the springs to be tested with different specifications, if the springs to be tested are longer, the height of the circular protective cylinder 6 is increased by the lifting rod 5, so that the distance from the circular protective cylinder 6 to the lower press plate 3 is increased; when the spring that awaits measuring is shorter, the height of the circular protective tube 6 of using lifter 5 to reduce, had both reduced the distance of circular protective tube 6 to holding down plate 3, can test the spring that awaits measuring of different specifications.
Referring to fig. 2, the circular protection cylinder 6 of the present technical solution includes a plurality of cylinder members 7 with different diameters, a plurality of convex edges 8 are disposed at one end of each cylinder member 7, and the plurality of cylinder members 7 are sleeved with each other and fixed to form the circular protection cylinder 6 through the convex edges 8. The circular protective tube 6 of the present embodiment is composed of 4 tube members.
Adopt this technical scheme, can further improve according to the size of the circular protective cylinder 6 of diameter adjustment of the spring that awaits measuring the utility model discloses a practicality.
Referring to fig. 2, in the present technical solution, the inner diameter of the larger cylinder 7 of the two adjacent cylinders 7 sleeved with each other is equal to the outer diameter of the smaller cylinder 7.
By adopting the technical scheme, the situation that the accuracy of the spring test is influenced due to the fact that two adjacent barrel parts 7 are offset when the spring is compressed on the circular protective barrel 6 because one of the two adjacent barrel parts 7 is too large and the other one is too small can be prevented.
