The following illustrates the functions and implementation processes of the detection method provided by this embodiment.
In practical applications, the detection method may be implemented by a computer program, for example, application software; alternatively, the method may also be implemented as a medium storing a related computer program, such as a hard disk, a cloud disk, or the like; still alternatively, the method may be implemented by a physical device, such as a chip, a terminal device, or the like, into which the relevant computer program is integrated or installed. The method will not be described below by way of example as being implemented by a detection system.
In addition, it is understood that: the detection method in the embodiment is not only suitable for the piston valve, but also suitable for other scenes needing to detect the compression condition of the elastic part; that is, the object to be inspected to which the detection method of the present embodiment is applied is not limited to the piston valve; the following embodiments merely exemplify the function and implementation of the present embodiment by taking the detected object as a piston valve.
The embodiment provides a method for detecting damping of a piston valve, wherein the piston valve comprises an elastic element; as shown in fig. 2, the detection method includes:
s101, acquiring a first deformation amount and a corresponding damping force variation amount when the elastic piece is compressed from a first measuring position to a second measuring position;
before the piston valve is detected, an electric gun mechanism of the assembly station performs pre-tightening on a nut for compressing the elastic member, so that the elastic member has an initial position, and the compression amount of the elastic member in the initial position relative to the free state is X 0 And the elastic part has an initial damping force F when in an initial position 0 . Wherein the elastic member includes, but is not limited to, a spring; the amount of compression is the length of the elastic member compressed in its axial direction, i.e., the amount of deformation occurring in its axial direction.
In the process of detecting the piston valve, the jacking screw of the controllable pressure detection mechanism continues to compress the elastic element, so that the elastic element continues to be compressed and has a first measuring position and a second measuring position; wherein the first measuring position has a distance from the initial position and the second measuring position has a distance from the first measuring position. In addition, the amount of compression when the elastic member is in the first measuring position relative to the free state is X 1 And has a first damping force F 1 (ii) a When the elastic member is in the second measuring position, the compression amount relative to the free state is X 2 And has a second damping force F 2 . In this way, the elastic element can be compressed by a compression X in the second measuring position relative to the free state 2 The amount of compression X relative to the free state when the resilient member is in the first measuring position 1 The difference therebetween as a first deformation (X) when the elastic member is compressed from the first measurement position to the second measurement position 2 -X 1 ) (ii) a A second damping force F when the elastic member is in the second measuring position 2 With a first damping force F when the resilient member is in the first measuring position 1 As a difference of (a) as a bulletThe amount of change (F) in the damping force when the element is compressed from the first measuring position to the second measuring position 2 -F 1 )。
In the concrete implementation process, the jacking screw is provided with a pressure sensor contact which can be used for measuring the elastic damping force of the elastic piece in the compression process, and the first damping force F when the elastic piece is compressed to the first measurement position can be obtained from the measurement result of the pressure sensor contact 1 And a second damping force F when the elastic member is compressed to a second measurement position 2 . In addition, a displacement sensor is arranged on the jacking screw rod or the surrounding parts of the jacking screw rod, and the displacement sensor is used for detecting the displacement of the elastic piece in the compression process.
S102, determining an elastic coefficient of the elastic piece according to the first deformation and the damping force variation;
i.e. according to the first deformation (X) 2 -X 1 ) And damping force variation (F) 2 -F 1 ) The spring constant k of the spring is determined. Illustratively, the damping force may be varied by an amount (F) 2 -F 1 ) With a first deformation (X) 2 -X 1 ) The quotient of (a) is taken as the elastic coefficient k of the elastic member; that is to say k ═ F 2 -F 1 )/(X 2 -X 1 )。
Since it is difficult to make the dimensions and properties of the elastic members identical for a plurality of elastic members of the same kind and in the same series, due to the impression of production factors such as the production process, etc., there may be differences between the elastic properties of the elastic members, for example, differences between the actual spring constants of the elastic members. The differences between the samples are illustrated by taking the elastic member as an example, and are specifically shown in table 1 below.
TABLE 1 basic spring dimensions and spring rates
It can be seen that the spring constants of different elastic members also differ for a plurality of springs of the same type and series.
In the embodiment, the actual elastic coefficient of the elastic element is determined according to the actually detected data, so that the accuracy of the initial damping force determined according to the elastic coefficient is improved, the accuracy of the compression force parameter of the elastic element is improved, and the accurate control of the compression condition of the elastic element is improved.
S103, determining an initial damping force when the elastic piece is located at an initial position according to the elastic coefficient;
in some examples, a second deformation amount of the elastic member when the elastic member is compressed from the initial position to the second measurement position may be obtained, that is, the elastic member may be compressed in the second measurement position relative to the elastic member in the free state by the compression amount X 2 The amount of compression X relative to the free state when the resilient member is in the initial position 0 The difference therebetween as a second amount of deformation (X) of the elastic member when it is compressed from the initial position to the second measurement position 2 -X 0 ). So as to be able to change according to the elastic coefficient k and the second deformation amount (X) 2 -X 0 ) And a second damping force F 2 Determining an initial damping force F of the elastic member at the initial position 0 。
Specifically, the second deformation amount (X) may be acquired 2 -X 0 ) Product k X (X) with elastic coefficient k 2 -X 0 ) (ii) a Obtaining a second damping force F 2 And the product k (X) 2 -X 0 ) Difference value F between 2 -k×(X 2 -X 0 ) (ii) a Determining the initial damping force F of the elastic part at the initial position according to the difference 0 ，F 0 ＝F 2 -k×(X 2 -X 0 )。
In other examples, a third deformation of the elastic member may be obtained when the elastic member is compressed from the initial position to the first measurement position, that is, the elastic member may be compressed in the first measurement position relative to the free state by the compression amount X 1 Amount of compression X relative to the elastic member in its initial position when in its free state 0 The difference between them, as a third deformation (X) of the elastic member from the initial compression to the first measuring position 1 -X 0 ). So as to be able to follow the elastic coefficient k and the third deformation (X) 1 -X 0 ) And a second damping force F 1 Determining an initial damping force F of the elastic member at the initial position 0 ’ ，F 0 ’ ＝F 1 -k×(X 1 -X 0 )
Since the elastic damping force of the elastic member is in a dynamic change process when the pressure sensor contact is just in contact with the elastic member at the initial position, it is difficult to accurately determine the initial damping force when the elastic member is at the initial position. Therefore, in this embodiment, the elastic coefficient of the elastic member is determined according to the relevant parameters at the first measurement position and the second measurement position measured in real time, and the initial damping force is determined according to the elastic coefficient and the relevant parameters at the second measurement position, or the initial damping force is determined according to the elastic coefficient and the relevant parameters at the first measurement position, the elastic damping forces at the first measurement position and the second measurement position are relatively stable, and the first measurement position and the second measurement position can respectively obtain the elastic damping forces in one-to-one correspondence, so that adverse effects caused by an unstable state where the pressure sensor contact is just in contact with the elastic member at the initial position can be avoided, the accuracy of the obtained initial damping force can be improved, and the accuracy of the damping of the piston valve can be improved.
S104, judging whether the initial damping force is qualified or not according to an actual difference value between the initial damping force and a preset standard damping force;
wherein the standard damping force can be preset according to the performance requirement of the piston valve and stored in the detection system.
In some examples, an actual difference between the initial damping force and the standard damping force may be obtained; judging whether the actual difference value is within a preset range or not; if the actual difference value is within the preset range, determining that the initial damping force is qualified; and if the actual difference value exceeds the preset range, determining that the initial damping force is unqualified. In a specific implementation, the standard damping force has an allowable deviation amount, and the allowable deviation amount can form a preset range; and if the actual difference value between the initial damping force and the standard damping force is within the allowable deviation amount, determining that the initial damping force is qualified.
For example, assume that the standard damping force of the spring at the initial position is 968N/mm, which allows a deviation of + -2N/mm; if the initial damping force actually obtained by an elastic part is 968.52N/mm, determining that the actual difference is 0.52N/mm, and determining that the initial damping force of the elastic part is qualified without adjusting the compression amount of the elastic part if the 0.52N/mm is within the range of-2N/mm; if the initial damping force actually obtained by the other elastic part is 970.05N/mm, the actual difference is determined to be 2.05N/mm, and if the actual difference is 2.05N/mm, the range of-2N/mm is exceeded, and the initial damping force of the elastic part is determined to be unqualified.
It can be understood that: the present embodiment is only illustrated here by way of example, and the standard damping force and the preset range of the elastic element are not limited thereto, and those skilled in the art can set the damping force and the preset range according to actual needs.
In other examples, the actual difference between the initial damping force and the standard damping force may also be obtained; and acquiring a quotient value between the actual difference value and the standard damping force, and judging whether the initial damping force is qualified or not according to the quotient value.
And S105, if the initial damping force is determined to be unqualified, determining the adjustment amount of the elastic piece according to the actual difference between the initial damping force and the standard damping force.
For example, if the initial damping force is determined to be unqualified, the supplementary compression amount of the elastic member can be determined according to the actual difference value and the elastic coefficient, so that the compression member compressing the elastic member can be adjusted according to the supplementary compression amount.
For example, let F be the standard damping force t Initial damping force F 0 And a standard damping force F t The deviation therebetween is Δ F; the quotient Δ F/k of the actual difference and the spring constant is obtained, and the supplementary compression Δ X of the spring is determined from the quotient, which is Δ F/k. For example, the compression amount of the elastic member needs to be increased by Δ X, and accordingly, the amount of movement of the compression member for compressing the elastic member in the axial direction of the elastic member and in the direction of continuing to compress the elastic member may be Δ X.
Therefore, the adjustment amount of the elastic piece is determined according to the deviation between the initial damping force and the standard damping force, so that the compression condition of the elastic piece can be adjusted according to the adjustment amount, the adjustment amount can provide a reliable basis for the subsequent adjustment of the compression condition of the elastic piece, and the initial damping force of the elastic piece can be adjusted to be qualified quickly and accurately. And determining that the damping force of the piston valve is qualified until the damping force of each elastic part in the piston valve is qualified.
According to the detection method provided by the embodiment, the elastic coefficient of the elastic part is determined according to the actually detected parameters, the initial damping force of the elastic part is determined according to the elastic coefficient and the actually detected parameters, and the adjustment quantity of the elastic part can be determined according to the actual difference between the initial damping force and the standard damping force when the initial damping force is determined to be unqualified, so that the accurate control of the compression quantity of the elastic part is favorably realized, the deviation of the elastic damping force of the elastic part relative to the standard damping force is reduced, and the qualification rate of products is favorably improved.
In one possible implementation, the compression member comprises an adjustment nut; the amount of movement of the adjustment nut in the axial direction of the elastic member can be adjusted by controlling the rotation of the adjustment nut when adjusting the amount of compression of the elastic member.
Accordingly, as shown in fig. 3, the detection method may include the steps of:
s201, acquiring a first deformation amount and a corresponding damping force variation amount when the elastic piece is compressed from a first measuring position to a second measuring position;
s202, determining an elastic coefficient of the elastic piece according to the first deformation and the damping force variation;
s203, determining the initial damping force of the elastic piece at the initial position according to the elastic coefficient, the second deformation of the second measurement position relative to the initial position and the second damping force;
s204, judging whether the initial damping force is qualified or not according to an actual difference value between the initial damping force and a preset standard damping force;
s205, if the initial damping force is determined to be unqualified, determining the supplementary compression amount of the elastic piece according to the actual difference and the elastic coefficient;
and S206, determining the supplementary tightening amount of the adjusting nut according to the supplementary compression amount and the thread pitch of the thread arranged on the adjusting nut, so as to control the adjusting nut to rotate according to the supplementary tightening amount.
The functions and specific implementation processes of steps S201 to S205 may be the same as those described above, and are not described herein again.
In step S06, the supplementary tightening amount of the adjusting nut is determined according to the supplementary compression amount Δ X and the pitch d of the thread provided on the adjusting nut, so that the adjusting nut can be adjusted according to the supplementary tightening amount.
Specifically, a quotient (DeltaX/d) of the supplementary compression quantity DeltaX and a thread pitch d of a thread provided on the adjusting nut is obtained, and a supplementary tightening angle R of the adjusting nut is determined according to the quotient (DeltaX/d). R360 ° × (Δx/d); then, Δ X ═ Δ F/k is substituted, and R ═ 360 ° × (Δf/Kd). The determined supplementary tightening angle R can be sent to the electric gun mechanism, and the electric gun mechanism drives the adjusting nut to continue to tighten according to the supplementary tightening angle R so as to compress the elastic piece, so that the compression condition of the elastic piece can meet the requirement.
In the specific implementation process, after the adjusting nut is driven to be screwed continuously according to the supplementary screwing angle R, the position of the elastic part can be used as a new initial position, the elastic part has a new initial damping force, and at the moment, the initial damping force of the elastic part can be detected by referring to the steps again until the initial damping force of the elastic part is qualified.
In a specific detection process, a plurality of elastic pieces in the piston valve can be respectively detected and adjusted; and when the initial damping force of each elastic element in the piston valve is proper, determining that the damping of the piston valve is qualified.
In the detection process, through the actual detection of the relevant parameters of the elastic parts, the deviation of the elastic damping force of each elastic part in the piston valve can be effectively reduced, and the production yield of the piston valve is favorably improved. In the detection process, the steps of manual participation are reduced, the adverse effect of human factors on the detection result is favorably reduced, the workload of operators is favorably reduced, and the production efficiency is favorably improved.
