Description

Technical Field

[0001] This application relates to the field of aerospace parts measurement technology, and in particular to a perpendicularity measuring device. Background Technology

[0002] During the repair of aerospace parts, some parts may deform to a certain extent during disassembly and assembly. To ensure the performance of the repaired parts, it is often necessary to use perpendicularity measuring tools to check their perpendicularity. However, some currently used perpendicularity measuring tools have the following problems:

[0003] First, the verticality is estimated by using measuring tools such as a verticality gauge, which is usually based on the user's experience and observation of the gap at the blade edge. This method of measuring verticality has a large error.

[0048] This example embodiment provides a verticality measuring device 100, such as... Figures 1 to 3 As shown, it includes:

[0049] A base 110, a support 111 is provided at one end of the base 110, a support rod 112 is provided at the other end of the base 110 relative to the support 111, and a hollow bushing 1115 is provided on the support 111.

[0050] Adjustment assembly 120 includes a rotating shaft 121 that passes through the hollow bushing 1115, and a handwheel 122 is connected to one end of the rotating shaft 121.

[0051] A clamping assembly 130 is provided, with one end of the clamping assembly 130 sleeved on the other end of the rotating shaft 121, and the other end of the clamping assembly 130 is used to fix the product 150 to be measured.

[0052] The measuring component 160 includes a measuring rod 161, which is horizontally mounted on the support rod 112. One end of the measuring rod 161 is equipped with a measuring gauge 162, and the other end of the measuring rod 161 is equipped with a measuring head 163. When measuring the verticality of the product 150 to be measured, the measuring head 163 contacts and connects with the product 150 to be measured.

[0053] The working principle of the verticality measuring device 100 proposed in this application is as follows:

[0054] First, the connecting part 152 of the product to be measured 150 is passed through the first through hole 134 and inserted into the groove 1214 of the rotating shaft 121;

[0055] Then, the guide 1333 of the spring collet 133 is fixed with the fastening screw 140, and the outer nut 131 is sleeved on the rotating shaft 121. The outer nut 131 is rotated to drive the sleeve 132 and the spring collet 133 to move, and the product to be measured 150 is fixed so that the measuring part 151 of the product to be measured 150 is in close contact with the end face of the outer nut 131.

[0056] Next, adjust the position of the measuring rod 161 on the support rod 112, and make the measuring head 163 contact and connect with the measuring part 151 of the product to be measured 150, and fix the measuring assembly 160.

[0057] Finally, turn the handwheel 122 one revolution to make the measuring head 163 contact the product 150 to be measured and read the maximum and minimum values ​​displayed on the measuring table 162. The difference between the maximum and minimum values ​​is the perpendicularity between the connecting part 152 and the measuring part 151 of the product 150 to be measured.

[0058] In one embodiment, such as Figure 4 and Figure 5 As shown, the bottom end of the support 111 is connected to the base 110, and the top end of the support 111 is provided with a semi-circular groove 1114, with a hollow bushing 1115 disposed within the semi-circular groove 1114. In this embodiment, the structure of the support 111 is specifically designed. The support 111 includes a support plate 1111, the bottom end of which is fixedly connected to the base 110. A rectangular groove 1112 is provided on the support plate 1111, the bottom end of the support column 1113 is inserted into the rectangular groove 1112, and the top end of the support column 1113 is provided with a semi-circular groove 1114, with the hollow bushing 1115 fitting into the semi-circular groove 1114.

[0059] In one embodiment, such as Figure 6 As shown, the hollow bushing 1115 is a hollow cylinder, and the outer diameter of the middle part of the rotating shaft 121, i.e., the second segment 1212, is matched with the inner diameter of the hollow bushing 1115. Figure 6 As can be seen, the rotating shaft 121 has been specifically designed in this embodiment. In this embodiment, the rotating shaft 121 is a three-section cylindrical structure connected in sequence. One end of the third section 1213 is connected to the outer nut 131, and the other end of the third section 1213 is sleeved on one end of the second section 1212. The other end of the second section 1212 is sleeved on one end of the first section 1211, and the other end of the first section 1211 is connected to the handwheel 122.

[0060] In one embodiment, on the side where the rotating shaft 121 connects to the handwheel 122, a washer 123 and an elastic washer 124 are sequentially arranged close to the end face of the hollow bushing 1115, and the washer 123 and the elastic washer 124 are respectively sleeved on the rotating shaft 121 and fastened with a hexagonal nut 125. In this embodiment, the washer 123 is preferably a nylon washer; the elastic washer 124 is preferably a wave-shaped elastic washer. The elastic washer 124 can compensate for the axial measurement error of the perpendicularity measuring device 100 and improve the accuracy of perpendicularity measurement.

[0061] In one embodiment, a groove 1214 is provided on the end face of the shaft 121 that is connected to the clamping assembly 130. One end of the clamping assembly 130 is sleeved on the outer wall of the groove 1214, and the other end of the clamping assembly 130 is provided with a first through hole. When the perpendicularity of the product 150 to be measured is measured, a part of the product 150 to be measured passes through the first through hole and extends into the groove 1214, and is fastened by the clamping assembly 130.

[0062] In one embodiment, the clamping assembly 130 includes an outer nut 131, a sleeve 132, and a spring collet 133 connected sequentially from the outside to the inside.

[0063] like Figure 7 As shown, one end of the outer nut 131 is sleeved on the rotating shaft 121, and the other end of the outer nut 131 is provided with a first through hole;

[0064] The inner wall of the outer sleeve nut 131 at one end of the first through hole is fitted and connected to the outer wall of the sleeve 132.

[0065] The sleeve 132 is fitted onto one end of the spring clip 133;

[0066] The other end of the spring collet 133 is fixedly connected to the rotating shaft 121;

[0067] Both the spring collet 133 and the sleeve 132 have gaps between themselves and the end face of the rotating shaft 121. These gaps provide sufficient space for the subsequent extension and retraction of the elastic element 1332.

[0068] Furthermore, such as Figure 8 As shown, the spring collet 133 includes a tapered member 1331, an elastic member 1332, and a guide member 1333 connected in sequence;

[0069] The outer wall of one end of the tapered member 1331 is fitted and connected to the inner wall of the sleeve 132, and the other end of the tapered member 1331 is sleeved on one end of the elastic member 1332.

[0070] One end of the guide member 1333 is sleeved on the other end of the elastic member 1332, and the other end of the guide member 1333 is fixedly connected to the inner wall of the rotating shaft 121.

[0071] The elastic member 1332 is provided with a plurality of first strip holes 1332a evenly, and the tapered member 1331 is provided with a plurality of second strip holes 1331a evenly, with the first strip holes 1332a and the second strip holes 1331a corresponding one to one.

[0072] When fastening the product to be measured 150, firstly, the guide 1333 is fixedly connected to the inner wall of the rotating shaft 121 by the fastening screw 140; then, the outer nut 131 is rotated, which drives the sleeve 132 and the spring collet 133 to move. The fastening process of the spring collet 133 is as follows: the outer nut 131 drives the tapered member 1331 to compress. The elastic member 1332 has a thin-walled structure. The setting of the first strip hole 1332a and the second strip hole 1331a is more conducive to one end of the elastic member 1332 gradually extending into the tapered member 1331 according to the compression force during compression. The other end of the elastic member 1332 drives the guide 1333 to compress. The internal thread of the outer nut 131 is matched with the external thread of the rotating shaft 121. When the measuring part 151 of the product to be measured 150 is close to the end face of the outer nut 131, the rotation of the outer nut 131 is stopped, thereby achieving the fastening of the product to be measured 150.

[0073] Furthermore, such as Figure 9 As shown, a first fixing hole is provided at one end of the rotating shaft 121 that is connected to the guide member 1333, and a second fixing hole that matches the first fixing hole is provided on the guide member 1333. The guide member 1333 and the rotating shaft 121 are fastened by fastening screws 140 that are simultaneously inserted into the first fixing hole and the second fixing hole.

[0074] In one embodiment, such as Figure 10As shown, the product to be measured 150 includes a measuring part 151 and a connecting part 152 connected to each other. The connecting part 152 is perpendicularly connected to the middle part of the measuring part 151. When measuring the perpendicularity of the product to be measured 150, the connecting part 152 passes through the first through hole, extends into the groove 1214, and is fastened to the product to be measured 150 by the clamping assembly 130.

[0075] In one embodiment, such as Figure 3 and Figure 11 As shown, the upper end of the support rod 112 is provided with at least one connecting hole, and two clamping walls 1121 are provided opposite to each other on the support rod 112 above the uppermost connecting hole. Each clamping wall 1121 is provided with a second through hole. The two second through holes match each other, and the two second through holes are provided with the same thread structure.

[0076] The measuring instrument 162 includes a dial 1621 and a housing 1622 connected to each other. When measuring the perpendicularity of the product 150 to be measured, after the measuring rod 161 passes through the housing 1622 and the second through hole in sequence, the measuring head 163 contacts and connects with the product 150 to be measured. At this time, the measuring assembly 160 is fixed by connecting the screw 1122 to the two second through holes.
