Technical Field

[0002] In the field of mechanical processing technology, sleeves are common mechanical structural components. They are hollow cylindrical in shape and are usually used to connect bearings and shafts. The outer diameter of the sleeve refers to the size of the outer diameter of the sleeve, which is one of the important parameters for measuring the machining accuracy of the sleeve.

[0003] In order to ensure the manufacturing accuracy and quality of mechanical parts, after the mechanical structural parts are manufactured, the shape and position dimensional elements of the corresponding parts need to be inspected. In the prior art, an outside diameter micrometer (or caliper) is often used to measure the outer diameter of the sleeve. Among them, the outside diameter micrometer generally includes a U-shaped scale frame, an anvil arranged at the left end of the scale frame, a micrometer screw located at the right end of the scale frame, and a reading mechanism. When actually measuring the outer diameter of the sleeve, it is necessary to hold the measuring object by hand so that the measured object is located in the U-shaped groove of the scale frame. By rotating the differential cylinder and the fine-tuning knob, the micrometer screw is driven toward the anvil, so that the micrometer screw and the anvil cooperate to clamp the measured object, and finally read the reading according to the reading mechanism.

[0004] In the process of actually measuring the outer diameter of the sleeve using the existing outside micrometer, it is necessary to hold the object to be measured and turn the differential cylinder and the fine adjustment knob at the same time to make the micro-measurement screw close to the anvil, and during the adjustment process, it is necessary to ensure that the position of the maximum outer diameter of the measured part of the object to be measured is aligned with the measuring surfaces of the micro-measurement screw and the anvil.

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-2 This application is described in further detail.

[0029] The embodiment of the present application discloses a tool for detecting the outer diameter of a sleeve.

[0030] Example 1

[0031] Reference Figure 1 The sleeve outer diameter detection tooling includes a U-shaped ruler frame 1, a measuring anvil 2 arranged at the left end of the ruler frame 1, a micrometer screw 3 and a reading mechanism 4 arranged at the right end of the ruler frame 1, an auxiliary clamping mechanism 5 arranged at one side of the ruler frame 1, and a ruler seat 6 for detachable assembly of the ruler frame 1. The auxiliary clamping mechanism 5 is used to assist in clamping the sleeve to be measured when the operator measures the sleeve to be measured.

[0032] Specifically, refer to Figure 1 and Figure 2 An adjusting screw 11 and a connecting guide rod 12 for installing the auxiliary clamping mechanism 5 are provided on one side of the ruler frame 1. The adjusting screw 11 and the connecting guide rod 12 are parallel to each other, and the adjusting screw 11 is vertically and movably arranged on the left end of the ruler frame 1, and one end of the connecting guide rod 12 is vertically and fixedly connected to the right end of the ruler frame 1.

[0033] The auxiliary clamping mechanism 5 includes a fixing seat 51 and a clamping block group and an elastic component installed on the fixing seat 51 .

[0034] Reference Figure 1 and Figure 2 The fixed seat 51 is in the shape of a rectangular plate. The fixed seat 51 is parallel to the ruler frame 1, and the two ends of the fixed seat 51 are movably mounted on the adjusting screw 11 and the connecting guide rod 12 respectively. The left end of the fixed seat 51 is threadedly adapted to the adjusting screw 11, and the right end of the fixed seat 51 is slidably connected to the connecting guide rod 12 along the axial direction of the connecting guide rod 12.

[0035] A linear slot 511 is formed on one side of the fixing seat 51 close to the ruler frame 1 , and the clamping block assembly includes a first clamping block 52 , a second clamping block 53 , a third clamping block 54 and a fourth clamping block 55 which are sequentially arranged in the slot 511 along the extending direction of the slot 511 .

[0036] The first clamp block 52 is located on a side of the fixed seat 51 close to the left end of the ruler frame 1, and the first clamp block 52 is fixedly connected to the fixed seat 51; the second clamp block 53, the third clamp block 54 and the fourth clamp block 55 are sequentially arranged on a side of the first clamp block 52 away from the left end of the fixed seat 51, and the second clamp block 53, the third clamp block 54 and the fourth clamp block 55 are all slidably connected in the slide groove 511 along the extension direction of the slide groove 511.

[0037] A linear guide rod 512 is also fixedly provided in the slide groove 511 for improving the sliding stability of the second clamp block 53, the third clamp block 54 and the fourth clamp block 55 in the slide groove 511. The extension direction of the guide rod 512 is consistent with the extension direction of the slide groove 511, and the second clamp block 53, the third clamp block 54 and the fourth clamp block 55 are all slidably mounted on the guide rod 512.

[0038] Reference Figure 2 The elastic component includes a first spring 56, a second spring 57 and a third spring 58. The first spring 56 is stretched between the second clamping block 53 and the left end of the fixing seat 51, the second spring 57 is stretched between the third clamping block 54 and the right end of the fixing seat 51, and the third spring 58 is compressed between the fourth clamping block 55 and the right end of the fixing seat 51. The first spring 56 can easily pull the second clamping block 53 and drive the second clamping block 53 to slide close to the first clamping block 52, and the second spring 57 and the third spring 58 can easily drive the third clamping block 54 and the fourth clamping block 55 to approach each other, thereby effectively clamping the object to be measured.

[0039] When measuring the sleeve to be measured, the operator can make the sleeve to be measured close to the fixed seat 51 vertically, and use the first clamp block 52 and the second clamp block 53 and the third clamp block 54 and the fourth clamp block 55 to clamp the two opposite side walls of the sleeve to be measured in the radial direction, or selectively use the first clamp block 52 and the second clamp block 53 to clamp the side wall of the sleeve to be measured close to the left end of the ruler frame 1, so as to clamp the sleeve to be measured on one side of the ruler frame 1, and then measure the outer diameter of the sleeve to be measured by the anvil 2, the micrometer screw 3 and the reading mechanism 4, so that the operator does not need to hold the sleeve to be measured all the time when measuring the sleeve to be measured. At the same time, the operator can also use the adjusting screw 11 to adjust the distance between the fixed seat 51 and the ruler frame 1, so that different parts of the object to be measured can be aligned with the anvil 2 and the micrometer screw 3 on the ruler frame 1, thereby improving the adaptability of the detection tooling.

[0040] Further, see Figure 1 and Figure 2 The first clamp block 52, the second clamp block 53, the third clamp block 54 and the fourth clamp block 55 have similar structural principles and all include a hemispherical portion, a cylindrical portion and a connecting portion that are integrally connected. The hemispherical portion is located at the end of the cylindrical portion away from the fixed seat 51, the connecting portion is located at the end of the cylindrical portion close to the fixed seat 51, and the connecting portion is sleeved on the guide rod 512. The center of the hemispherical portion is the center of the end surface of the cylindrical portion close to the ruler frame 1, and the radius of the hemispherical portion is consistent with the radius of the cylindrical portion. Through the combination of the hemispherical portion and the cylindrical portion, the first clamp block 52, the second clamp block 53, the third clamp block 54 and the fourth clamp block 55 can be more conveniently placed inside the sleeve to be measured, and effectively adapt to the surface of the object to be measured, thereby achieving effective clamping of the object to be measured.

[0041] Furthermore, flexible pads are fixedly provided on the surfaces of the first clamping block 52 , the second clamping block 53 , the third clamping block 54 and the fourth clamping block 55 to reduce damage to the surface of the object to be measured.

[0042] Reference Figure 1 The ruler seat 6 includes a supporting base 61, a clamping seat 62 rotatably arranged on the supporting base 61, and a first adjusting component 63 for adjusting the rotation of the clamping seat 62 on the supporting base 61, and the rotation axis of the clamping seat 62 is arranged horizontally; a clamping block 64 for cooperating with the clamping seat 62 to clamp the ruler frame 1 and a second adjusting component 65 for driving the clamping block 64 to slide linearly toward or away from the clamping seat 62, the sliding direction of the clamping block 64 is perpendicular to the rotation axis of the clamping seat 62, and the second adjusting component 65 and the first adjusting component 63 are both adjusting screws 11.

[0043] By screwing the second adjusting component 65, the operator can remove or connect the ruler frame 1 from the ruler base 6 according to the specific usage scenario; by screwing the first adjusting component 63 and rotating the clamping seat 62 on the support base 61, the operator can more conveniently adjust the horizontal height and the facing angle of the clamping seat 62, thereby facilitating the operator to observe the specific reading of the reading mechanism 4.

[0044] The implementation principle of a sleeve outer diameter detection tooling of the embodiment of the present application is as follows: when detecting the sleeve to be measured, the operator can selectively load and unload the ruler frame 1 on the ruler seat 6 through the first adjustment component 63 and the second adjustment component 65 in advance, and selectively use the first clamping block 52, the second clamping block 53, the third clamping block 54 and the fourth clamping block 55 to clamp the side wall of the sleeve to be measured close to the left end of the ruler frame 1 or clamp the two opposite side walls of the sleeve to be measured in the radial direction, and clamp the sleeve to be measured to one side of the ruler frame 1, and then use the measuring anvil 2, the micrometer screw 3 and the reading mechanism to adjust the diameter of the sleeve to be measured. 4 is used to measure the outer diameter of the sleeve to be measured, so that the operator does not need to keep the sleeve to be measured in hand when measuring the sleeve to be measured, which effectively improves the flexibility of the detection tooling operation, so that a single person can use the detection tooling to measure the object to be measured, and the operation is more convenient; at the same time, the operator can use the adjusting screw 11 and the connecting guide rod 12 to adjust the distance between the fixed seat 51 and the ruler frame 1, so that different parts of the object to be measured can be aligned with the measuring anvil 2 and the micrometer screw 3 on the ruler frame 1, so that the detection tooling is suitable for different occasions.
