Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
In the description of the present invention, it should be noted that the orientations or positional relationships indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like are based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
The invention relates to a method for selecting and matching belt pulley baffle gaskets of an automobile air-conditioning compressor, which comprises the following steps as shown in figures 2-3:
s10: measuring the vertical distance between the first clearance surface 06 of the belt pulley 02 and the first abutting surface 04 of the rotor 01 and recording the vertical distance as A; the perpendicular distance between the second clearance surface 07 and the second abutment surface 05 on the shutter 03 is measured and denoted B.
S20: calculating the theoretical thickness D of the gasket, wherein the calculation formula is as follows: d = A + C-B and the ratio of C-B,
wherein C is a gap constant, and is 0.3-0.6;
the specific principle is shown in fig. 2, and in the automotive air conditioning compressor, the following dimensional chain relationship can be extracted: b + D = a + C; and C is the distance of the gap after assembly, and the allowable range of the distance is fixed to be 0.3-0.6, so if the distance C of the gap after assembly is ensured not to exceed the tolerance, a relational expression of the theoretical thickness D = A + C-B of the gasket is obtained by regarding the distance C as a constant, the thickness to which the gasket should be set in theory is deduced in a reverse mode, and the actual thickness of the gasket can be selected for installation by taking the theoretical thickness D of the gasket as a reference. Because a certain numerical difference inevitably exists between the actual thickness of the gasket and the theoretical thickness D of the gasket, the value of C is preferably the middle value of the allowable range, namely 0.45, and the value of C can be prevented from being out of tolerance due to the influence of the numerical difference to the maximum extent.
S30: artificially setting a threshold interval and a plurality of different gasket thicknesses;
all gasket combinations are then determined, each satisfying the following conditions: the sum of the thicknesses of all the gaskets in the combination is recorded as E, and the value of E-D is within a threshold interval; what is specifically meant is the resulting gasket combination, such as a gasket combination of: 1 gasket with the thickness of 1mm and 1 gasket with the thickness of 0.3mm, 1 gasket group with the thickness of E =1.3mm can be obtained by using the combined gasket, the difference between the gasket group with the thickness of E =1.3mm and the theoretical thickness D of the gasket is judged by the value of E-D, and when the difference is in a threshold interval, the assembled C value can be ensured to be in the range of 0.3-0.6, and the gasket group can be used for installation;
and then outputting data of the shim combination with the minimum total number of used shims in all shim combinations, such as: finding that both combinations of shims can meet within a threshold interval, one is: 1 gasket with the thickness of 1mm and 1 gasket with the thickness of 0.3mm, wherein the number of the gaskets is 2; the other one is as follows: 1 gasket with the diameter of 1mm and 2 gaskets with the diameter of 0.15mm, wherein the number of the gaskets is 3; the output data for the shim combination is then: 1 individual 1mm gasket and 1 individual 0.3mm gasket to the quantity of minimize gasket prevents because the too much integral damage rate that leads to of gasket quantity increases and the inconvenient problem of installation.
S40: the gasket combination corresponding to the output data is placed on the first abutting surface 04, then the baffle 03 is sleeved on the rotor 01, the second abutting surface 05 abuts against the gasket, and then the baffle 03 and the rotor 01 are fixed through screws to complete assembly.

set up 1mm, 0.3mm, 0.2mm and 0.15mm gasket thickness, the gasket of above thickness is the gasket thickness of commonly using in the market, can purchase the use conveniently, does not need additional processing, then has E's computational formula to be this moment:
E=w+0.3x+0.2y+0.15z
wherein w is the number of 1mm gaskets; x is the number of 0.3mm gaskets; y is the number of 0.2mm shims; z is the number of 0.15mm gaskets, and w, x, y and z are all 0 or positive integers;
by taking one value for each of w, x, y, z and making the value of E-D fall within the threshold interval, a pad combination can be formed, for example: when w =1, x =1, y =0, and z =0 can satisfy that the E-D value falls within the threshold interval, w =1, x =1, y =0, and z =0 is a solution of one shim combination, which means that 1 shim of 1mm, 1 shim of 0.3mm, 0 shim of 0.2mm, and 0 shim of 0.15mm are used.
Preferably, in step S30, when finding the gasket combination, w, x, y, and z are sequentially taken from 0, that is, in the calculation, the number of the thickest gaskets is selected so that the thickness E of all the gaskets is closest to the theoretical thickness D of the gasket, then the number of the gaskets with a slightly smaller thickness is selected so that the thickness E of all the gaskets is closest to the theoretical thickness D of the gasket, and the number of the gaskets with a smaller thickness is selected, so that the gasket combination with the smallest total number of useless gaskets can be directly found, and thus, it is not necessary to find other gasket combinations, thereby improving the calculation efficiency.
Preferably, the following steps are further included after step S40:
s50: and establishing and iterating a comparison library, recording each gasket combination output by the S30 and the corresponding D value, and forming a selection interval corresponding to each gasket combination according to the D values recorded for multiple times. Specifically, after a plurality of data records, a plurality of gasket combinations are generated, and each gasket combination has a plurality of corresponding D values, and at this time, an interval can be formed according to the maximum value and the minimum value of the corresponding D value in each gasket combination, and the interval is a selection interval. A plurality of selection intervals and a corresponding plurality of shim combinations may form a contrast library.
Preferably, between steps S20 and S30, the following steps are further included:
s25: putting the D value into a comparison library for judgment, and if the D value falls into one of the existing multiple selection intervals, outputting the corresponding gasket combination and directly executing the step S40, so that a more complicated calculation step is omitted, and data of the gasket combination can be quickly output; if the D value does not fall within the existing selection interval, step S30 is executed to calculate pad combination data, and the calculated data is used to perfect the comparison library: if the gasket combination calculated this time does not belong to the gasket combination in the comparison library, forming a new gasket combination and a corresponding selection interval in the comparison library; if the gasket combination calculated this time belongs to the gasket combination in the comparison library, adjusting the corresponding selection interval according to the D value in the calculation: when the current D value is smaller than the minimum end of the selection interval, replacing the value of the minimum end of the selection interval with the current D value; and when the current D value is larger than the maximum end of the selection interval, replacing the value of the maximum end of the selection interval with the current D value.
