Description

Technical Field

[0001] The invention relates to the field of measurement technology, and in particular to a method for quickly measuring the height of a vibration isolator. Background Art

[0002] The vibration isolator is installed on the base, which can effectively reduce the vibration of the diesel engine transmitted to the base and reduce the forced vibration of the base. However, since the vibration isolator is located between the base and the diesel engine, the space is small and there are many electromechanical equipment, which is not convenient for personnel to measure directly. If the compression (height) of each vibration isolator is uneven or exceeds the specified value, it will cause some vibration isolators to bear too little weight while some are too large, which is not conducive to the vibration reduction effect. If there are a large number of vibration isolators, the staff needs to measure the height of each vibration isolator separately, and then adjust the height of the vibration isolator until the height difference of each vibration isolator meets the design requirements. This method requires multiple measurements, which takes a lot of time and effort, resulting in waste of resources and potential personnel danger. Therefore, how to provide a method for quickly measuring whether the height of the vibration isolator meets the design requirements has become a technical problem that urgently needs to be solved. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a method for quickly measuring the height of a vibration isolator. It is not necessary to use a ruler to measure the height of each vibration isolator. Through a telescopic device, it is possible to quickly and accurately measure whether the height of the vibration isolator meets the design requirements, thereby reducing measurement time and improving work efficiency.

[0004] The method for quickly measuring the height of a vibration isolator according to the present invention comprises the following steps:

[0005] S1 uses a ruler to measure the height of each vibration isolator (i.e., the height from the base to the support) and records them separately; since the space from the base to the support is very narrow and semi-enclosed, the ruler cannot be inserted into this area, and only the height of the vibration isolator can be roughly measured;

[0006] S2 selects a telescopic device, the height of which in the first state is equal to or slightly less than the minimum value measured by the ruler in step S1, and the height of which in the second state is greater than the maximum value measured by the ruler in step S1;

[0007] S3: placing the telescopic device on one side of each vibration isolator, and adjusting the height of the telescopic device so that the lower end surface of the telescopic device contacts the base, and the upper end surface of the telescopic device contacts the support, so as to measure the height of each vibration isolator, and respectively record the measured heights, and calculate the average height h of the vibration isolator according to the measured heights;

[0008] S4 selects two sets of the telescopic devices according to the average height h of the vibration isolator, adjusts the height of the first set of telescopic devices to h+x, and adjusts the height of the second set of telescopic devices to hx, where x is 1 / 2 of the standard value of the compression unevenness of the vibration isolator.

[0009] S5 inserts the two sets of the telescopic devices between each base and the support respectively. If the second set of telescopic devices can be inserted but the first set of telescopic devices cannot be inserted, it means that the height of the vibration isolator meets the requirements; if the second set of telescopic devices cannot be inserted, it means that the distance between the base and the support is too small, that is, the height of the vibration isolator is too low, and the distance between the base and the support needs to be increased; if the first set of devices can be inserted, it means that the distance between the base and the support is too large, that is, the height of the vibration isolator is too high, and the distance between the base and the support needs to be reduced.

[0010] According to the measuring method of the present invention, there is no need to use a ruler to measure the height of the vibration isolator. It is only necessary to select two sets of telescopic devices that meet the requirements. The length of the first set of telescopic devices is the upper limit of the height of the vibration isolator, and the length of the second set of telescopic devices is the lower limit of the height of the vibration isolator. The two sets of telescopic devices are respectively inserted between the base and the support. If the second set of telescopic devices can be inserted, but the first set of telescopic devices cannot be inserted, it means that the height of the vibration isolator meets the requirements; if the second set of telescopic devices cannot be inserted, it means that the height of the vibration isolator is too low, and the distance between the base and the support needs to be increased; if the first set of devices can be inserted, it means that the height of the vibration isolator is too high, and the distance between the base and the support needs to be reduced, so as to quickly and accurately measure whether the height of the vibration isolator meets the requirements, thereby greatly improving work efficiency.

[0011] In some embodiments, the telescopic device includes, from top to bottom, a telescopic part Ⅰ1, a nut Ⅰ2, a nut Ⅱ4, a nut Ⅲ5 and a telescopic part Ⅱ3, wherein the nut Ⅰ2 and the nut Ⅲ5 are respectively mounted on the telescopic part Ⅰ1 and the telescopic part Ⅱ3, and one end of the telescopic part Ⅰ1 and the telescopic part Ⅱ3 are respectively threadedly connected to the two ends of the nut Ⅱ4.

[0012] In some embodiments, the telescopic member Ⅰ1 and the telescopic member Ⅱ3 are standard coarse threads or fine threads.

[0013] In some embodiments, the telescopic member Ⅰ1 and the telescopic member Ⅱ3 are screws or studs.

[0014] In some embodiments, the nut I2, the nut II4 and the nut III5 are standard nuts.

[0015] In some embodiments, the telescopic device may also be composed of a housing and a telescopic member disposed inside the housing, wherein the outer wall of the telescopic member is threadedly connected to the inner wall of the housing and can move up and down relative to the housing. In order to facilitate adjustment of the length of the telescopic member extending out of or retracting into the housing, in some embodiments, a nut IV is further included, which is sleeved on the telescopic member.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1) The traditional method uses a ruler for measurement. Since the ruler cannot be inserted into the measurement area, it can only be measured from the outside. Due to the small space in the measurement area, it is difficult for operators to read horizontally, and the measurement deviation is inaccurate. The telescopic device using this measurement method can be inserted into a semi-enclosed space, and then a vernier caliper or other measuring tools are used to measure the height of the telescopic device, thereby obtaining the height of the isolator to achieve accurate measurement, reducing the inconvenience of personnel operation and measurement accuracy. At the same time, the upper and lower limits of the height of the isolator are obtained based on the average height of the isolator. A set of telescopic devices with an upper limit value of the isolator height and a set of telescopic devices with a lower limit value of the isolator height are used to quickly and accurately measure whether the height of each isolator meets the design requirements. There is no need to repeatedly measure and adjust the height of each isolator, which greatly saves measurement time and measurement resources and improves work efficiency.

[0018] 2) If an internal bore micrometer is used, it is difficult to adapt to the requirements of all models because the weights of different diesel engines are different, resulting in different compression amounts of the isolators. However, the present invention flexibly selects the length of the telescopic device according to the height of the isolator, avoiding the need to use different feeler gauges for different compression amounts of the isolators, making measurement more convenient.

[0019] 3) The present invention uses two sets of telescopic devices to quickly measure whether the height of the vibration isolator meets the requirements, which saves measurement time and measurement resources and greatly improves work efficiency.

[0020] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides various specific processes and examples of materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0033] Example 1: See Figures 1 to 4 and Figure 8 The present embodiment provides a method for quickly measuring the height of the vibration isolator 80, and the specific steps are as follows:

[0034] S1 uses a ruler to measure the height of each vibration isolator 80 (i.e., the height from the base 200 to the support 101), and records them respectively; since the space from the base 200 to the support 101 is very narrow and semi-enclosed, the ruler cannot be inserted into the area, and only the height of the vibration isolator 80 can be roughly measured;

[0035] S2 selects a telescopic device, which includes a screw I10, a nut I20, a nut II40, a nut III50 and a screw II30 from top to bottom, wherein the nut I20 and the nut III50 are respectively sleeved on the screw I10 and the screw II30, one end of the screw I10 and the screw II30 are respectively threadedly connected to the two ends of the nut II40, the height of the telescopic device in the first state is equal to or slightly less than the minimum value measured by the ruler in step S1, and the height of the telescopic device in the second state is greater than the maximum value measured by the ruler in step S1;

[0036] The first state of the telescopic device is the retracted state, that is, the ends of the screw I10 and the screw II30 located in the nut II40 are in contact, at this time, the three nuts are in close contact, and the nut I20 and the nut III50 are both in a tightened state, see Figure 1 and Figure 2 , the structural diagram of screw Ⅰ10 and screw Ⅱ30 is shown in Figure 4 The second state of the telescopic device is the fully extended state, that is, the ends of the screw Ⅰ10 and the screw Ⅱ30 are located at the two ends of the nut Ⅱ40, see Figure 3 The nut I20, the nut II40 and the nut III50 are standard nuts.

[0037] S3 inserts the telescopic device between the base 200 and the support 101 of the diesel engine 100, and places the telescopic device on one side of each of the vibration isolators 80. When measuring, first make the lower end surface of the screw screw II 30 contact the base 200, and then adjust the height of the telescopic device, that is, rotate the nut I 20 clockwise to make the screw I 10 extend outward until the upper end surface of the screw I 10 contacts the support 101, take out the telescopic device, and measure the length of the telescopic device with a vernier caliper or other measuring tools to obtain the height of each of the vibration isolators 80, and record the measured heights respectively, and calculate the average height h of the vibration isolators 80 according to the measured heights;

[0038] S4 According to the average height h of the vibration isolator 80, the vibration isolator 80 is measured by using two sets of the telescopic devices, and the height of the first set of telescopic devices 90 is adjusted to h+x, that is, the upper limit of the height of the vibration isolator 80, and the height of the second set of telescopic devices 91 is adjusted to hx, that is, the lower limit of the height of the vibration isolator 80, where x is 1 / 2 of the standard value of the uneven compression of the vibration isolator 80, which is provided by the manufacturer of the vibration isolator 80;

[0039] S5 inserts the two sets of the telescopic devices respectively between each base 200 and the support 101. If the second set of telescopic devices 91 can be inserted, but the first set of telescopic devices 90 cannot be inserted, it means that the height of the vibration isolator 80 meets the requirements; if the second set of telescopic devices 91 cannot be inserted, it means that the distance between the base 200 and the support 101 is too small, that is, the height of the vibration isolator 80 is too low, and the distance between the base 200 and the support 101 needs to be increased; if the first set of devices can be inserted, it means that the distance between the base 200 and the support 101 is too large, that is, the height of the vibration isolator 80 is too high, and the distance between the base 200 and the support 101 needs to be reduced, so as to quickly and accurately measure whether the height of each vibration isolator 80 meets the design requirements, effectively saving measurement time and labor costs, improving work efficiency, and being beneficial to improving the economic benefits of the enterprise.

[0040] Embodiment 2: Different from Embodiment 1, the telescopic device of this embodiment includes a housing 70 and a telescopic member 60 disposed inside the housing 70. The outer wall of the telescopic member 60 is provided with an external thread, and the housing 70 is provided with an internal thread matching the external thread. The outer wall of the telescopic member 60 is threadedly connected to the inner wall of the housing 70 and can extend outward or retract inward relative to the housing 70. Figure 5 The telescopic member 60 of this embodiment can be a stud; in order to facilitate the adjustment of the length of the telescopic member 60 extending or retracting into the housing 70, see Figure 5 The end of the telescopic member 60 away from the bottom of the housing 70 is sleeved with a nut IV61, and the nut IV61 is fixedly connected to the telescopic member 60, so that the length of the telescopic member 60 extending outward can be adjusted by rotating the nut IV61, thereby adjusting the height of the entire telescopic device. In order to prevent the telescopic member 60 from detaching from the inside of the housing 70, see Figure 6 and Figure 7 An annular limiting plate 71 can be connected circumferentially to the inner wall of the opening end of the shell 70, and the outer wall of the telescopic member 60 is threadedly connected to the inner wall of the annular limiting plate 71. An annular baffle 62 is circumferentially connected to the outer wall of the telescopic member 60 near the bottom of the shell 70. When the telescopic member 60 extends outward, the annular limiting plate 71 limits the annular baffle 62 from extending outward from the shell 70, thereby limiting the telescopic member 60 from continuing to extend outward from the shell 70, thereby effectively preventing the telescopic member 60 from detaching from the inside of the shell 70.

[0041] The specific measurement method is as follows:

[0042] S1 uses a ruler to measure the height of each vibration isolator 80 (i.e., the height from the base 200 to the support 101), and records them respectively; since the space from the base 200 to the support 101 is very narrow and semi-enclosed, the ruler cannot be inserted into the area, and only the height of the vibration isolator 80 can be roughly measured;

[0043] S2 selects a telescopic device, the height of which in the first state is equal to or slightly less than the minimum value measured by the ruler in step S1, and the height of which in the second state is greater than the maximum value measured by the ruler in step S1;

[0044] The first state of the telescopic device is the retracted state of the telescopic member 60, that is, the telescopic member 60 is retracted into the housing 70, and only the nut IV 61 is exposed outside the housing 70, so as to adjust the telescopic member 60 to extend out of the housing 70, see Figure 6 The second state of the telescopic device is the telescopic member 60 extended state, that is, the telescopic member 60 mostly extends outward from the housing 70, see Figure 7 ;

[0045] S3 See Figure 8 , insert the telescopic device between the base 200 and the support 101 of the diesel engine 100, and place the telescopic device on one side of each of the vibration isolators 80, adjust the height of the telescopic device by rotating the telescopic member 60 clockwise or counterclockwise until the upper end surface of the telescopic member 60 contacts the support 101 and the lower end surface of the telescopic member 60 contacts the base 200, then take out the telescopic device, measure the length of the telescopic device with a vernier caliper or other measuring tools to obtain the height of each of the vibration isolators 80, and record the measured heights respectively, and calculate the average height h of the vibration isolators 80 according to the measured heights;

[0046] S4 According to the average height h of the vibration isolator 80, the vibration isolator 80 is measured by using two sets of the telescopic devices, and the height of the first set of telescopic devices 90 is adjusted to h+x, that is, the upper limit of the height of the vibration isolator 80, and the height of the second set of telescopic devices 91 is adjusted to hx, that is, the lower limit of the height of the vibration isolator 80, where x is 1 / 2 of the standard value of the uneven compression of the vibration isolator 80, which is provided by the manufacturer of the vibration isolator 80;

[0047] S5 inserts the two sets of the telescopic devices respectively between each base 200 and the support 101. If the second set of telescopic devices 91 can be inserted, but the first set of telescopic devices 90 cannot be inserted, it means that the height of the vibration isolator 80 meets the requirements; if the second set of telescopic devices 91 cannot be inserted, it means that the distance between the base 200 and the support 101 is too small, that is, the height of the vibration isolator 80 is too low, and the distance between the base 200 and the support 101 needs to be increased; if the first set of devices can be inserted, it means that the distance between the base 200 and the support 101 is too large, that is, the height of the vibration isolator 80 is too high, and the distance between the base 200 and the support 101 needs to be reduced, so as to quickly and accurately measure whether the height of each vibration isolator 80 meets the design requirements, effectively saving measurement time and labor costs, improving work efficiency, and being beneficial to improving the economic benefits of the enterprise.
