Description
Technical Field
The utility model relates to a test field, concretely relates to heavy spring rate of high accuracy detects anchor clamps.
Background
The high-precision heavy springs commonly used on the products of pipe fitting valve enterprises have the precision matching requirements of position and load, and the precision test of the spring stiffness can be carried out in the feeding inspection of the springs. At present, a spring stiffness testing machine is shown in an attached figure 1 and comprises a machine body 1, a load dial 2, a testing rod 3, a testing rod relative displacement reading meter 4, a spring 5, a spring base 6 and a pressing block 7. The spring 5 is placed on the spring base 6, the pressing block 7 compresses the spring 5 downwards, the test rod relative displacement reading meter 4 displays the moving displacement of the test rod 3, and the test machine adopts the test rod relative displacement reading to represent the spring displacement. For a spring with heavy load, when the pressing block 7 compresses the spring 5 downwards, the testing rod 3 generates a certain deformation, and the deformation of the testing rod 3 is counted into the displacement of the spring 5, so that the real deformation of the spring 5 cannot be accurately determined, and the K value of the spring 5 is inaccurate to calculate.
SUMMERY OF THE UTILITY MODEL
In order to solve the not enough of prior art, the utility model provides a heavy spring rate of high accuracy detects anchor clamps, including bottom plate, supporting shoe, curb plate, percentage table, the curb plate sets up on the bottom plate, the supporting shoe sets up on the curb plate, be provided with the probe on the percentage table, the probe sets up perpendicularly on the supporting shoe, the probe stretches out the height of supporting shoe can be according to the original length of being surveyed the spring and adjust from top to bottom.
The utility model has the advantages that the real deformation displacement of the tested spring can be directly read through the dial indicator, so that the K value of the tested spring can be accurately calculated; and simultaneously the utility model is simple in operation, the inspection efficiency is high, to the bigger, the higher spring of load of size, only need adjust the part size, the commonality is strong.

Detailed Description
In order to facilitate understanding for those skilled in the art, the present invention will be further described with reference to the accompanying drawings.
Referring to the attached figure 2, the utility model comprises a bottom plate 12, a side plate 10, a supporting block 9 and a dial indicator 11. The lower end of the side plate 10 is fixed on the bottom plate 12 through a screw 14, and the supporting block 9 is connected to the upper end of the side plate 10 through a screw 13. The dial indicator 11 is connected with a measuring pin 8, and the measuring pin 8 is vertically arranged in a central hole 20 of the supporting block 9 and is locked by a base meter screw 16.
The supporting blocks 9, the side plates 10 and the bottom plate 12 are all made of Cr12 and are subjected to heat treatment HRC 55-60. The upper surface 18 of the supporting block 9 is processed by a precision grinder, so that the flatness of the supporting block is within 0.01 mm. After the supporting block 9, the side plates 10 and the bottom plate 12 are assembled together, the lower surface 22 of the bottom plate 12 is finely ground by using the upper surface 18 of the supporting block 9 as a reference, so that the parallelism between the upper surface 18 of the supporting block 9 and the lower surface 22 of the bottom plate 12 is within 0.02mm, and the whole clamp is ensured to be placed on a horizontal plane of a testing machine and be parallel to each other. In addition, in order to ensure that the compression displacement of the spring is consistent with the stretching direction of the measuring needle 8 on the dial indicator 11, the verticality of the measuring needle 8 and the supporting block 9 is controlled within 0.02 mm.
Will the utility model discloses place under the spring test machine, place heavy load spring 5 on supporting shoe 9, through elasticity basic meter screw 16, adjustment measuring pin 8 stretches out the height of supporting shoe 9, makes its extension length be a little higher than spring 5 upper surface, when load dial plate 2 and percentage table 11 all have less reading, "sets zero" simultaneously, has utilized the linear stack principle here. And continuing loading, when the pressing block 7 is downwards the tested spring 5, the measuring needle 8 stretches downwards, and the reading of the dial indicator 11 is the deformation displacement of the tested spring 5. Therefore, the K value of the tested spring can be accurately calculated.
The invention has been described with reference to the preferred embodiments, to the above examples which are not intended to limit the invention, and from reading the present description, those skilled in the art will be able to conceive of numerous modifications and variations to this structure, without departing from the inventive concept, any obvious alternative falling within the scope of the invention.
