[0030] Reference Figures 1 to 4 The utility model provides a new curved surface track detection device, including a bracket component 1, a rotating component 2, and a micrometer 3.

[0031] The bracket assembly 1 includes a main bracket 11, a workbench 12 and a base 13 connected in sequence from top to bottom. The base 13 is located at the bottom and plays a supporting role. The workbench 12 has a flat surface and can maintain the stability of the main bracket 11.

[0032] The main support 11 includes a first layer plate 111, a second layer plate 112, a third layer plate 113, a fixing sleeve 114 and a lateral frame body 115;

[0033] The two lateral frames 115 are symmetrically connected to the two ends of the first layer board 111, the two ends of the second layer board 112, and the two ends of the third layer board 113. The lateral frames 115 can support the first layer board 111, the second layer board 112, and the third layer board 113, and can also maintain the first layer board 111, the second layer board 112, and the third layer board 113 at different corresponding heights.

[0034] The second layer plate 112 is located below the first layer plate 111, and the third layer plate 113 is located below the second layer plate 112. The fixing sleeve 114 is connected to the first layer plate 111 and is preferably located at a relative position in the middle. The rotating assembly 2 is placed on the fixing sleeve 114 and its bottom end can pass through the fixing sleeve 114.

[0035] The reference part 4 is placed on the second layer 112 of the main support 11, and the test piece 5 is placed on the third layer 113 of the main support 11. The reference part 4 and the test piece 5 are located at different heights on the same axis.

[0036] The reference part 4 is a qualified product, and the part to be tested 5 is a product waiting to be tested. During the testing process, the reference part 4 can be kept in place all the time and does not need to be replaced frequently. It is only necessary to replace different parts to be tested 5 and place different parts to be tested 5 on the third layer board 113. In addition, the placement positions of the reference part 4 and the part to be tested 5 can also be interchanged. This embodiment preferably adopts the placement method of placing the reference part 4 on the top and the part to be tested 5 on the bottom for display.

[0037] The rotating assembly 2 includes a turntable 21, a spindle structure 22 and a dial indicator bracket 23;

[0038] The spindle structure 22 specifically includes a rotating spindle 221, a height positioning sleeve 222 and a quick plug-in pin 223;

[0039] The outer diameter of the height positioning sleeve 222 is larger than the inner diameter of the fixing sleeve 114, so that the height positioning sleeve 222 can be placed on the fixing sleeve 114, and the fixing sleeve 114 can support the height positioning sleeve 222 to maintain the relative height of the two unchanged;

[0040] The outer diameter of the rotating spindle 221 is slightly smaller than the inner diameter of the height positioning sleeve 222. The rotating spindle 221 passes through the height positioning sleeve 222 and the fixed sleeve 114 from top to bottom. At the same time, the rotating spindle 221 and the height positioning sleeve 222 are connected by a quick plug-in pin 223, and the relative position between the rotating spindle 221 and the height positioning sleeve 222 can be adjusted by quickly plugging and unplugging the quick plug-in pin 223.

[0041] The turntable 21 is connected to the top of the rotating spindle 221, and the connection here is preferably a bolt connection, which makes disassembly and assembly more convenient and quick. The dial indicator bracket 23 is connected to the lower part of the rotating spindle 221, and the connection here is preferably a bolt connection, which makes disassembly and assembly more convenient and quick;

[0042] There are two dial gauges 3, which are connected to the dial gauge bracket 23. The two dial gauges 3 correspond to the reference part 4 and the part to be inspected 5 in the vertical direction. The dial gauges 3 can be mechanical or more advanced electronic, and can be flexibly selected according to actual use requirements.

[0043] Use external force to rotate the turntable 21. The rotation of the turntable 21 can drive the main shaft structure 22 and the two micrometers 3 to rotate synchronously. The two micrometers 3 can compare and detect the inner wall curved surface of the reference part 4 and the inner wall curved surface of the part to be inspected 5. During the inspection process, the relative positions of the micrometer 3, the reference part 4 and the part to be inspected 5 can also be adjusted through the quick plug-in pin 223, so that the micrometer 3 can respectively inspect the upper, middle and lower parts of the inner wall curved surface, making the inspection result more accurate.

[0044] In this embodiment, the new curved surface trajectory detection device further includes a guide positioning assembly 6, which can simultaneously pass through the main support 11, the reference workpiece 4, and the workpiece to be tested 5. After the reference workpiece 4 and the workpiece to be tested 5 are placed on the main support 11, the guide positioning assembly 6 can guide and position the reference workpiece 4 and the workpiece to be tested 5 to ensure that the reference workpiece 4 and the workpiece to be tested 5 are located on the same axis, making the comparison detection of the dial indicator 3 more accurate.

[0045] Specifically, the guide positioning assembly 6 preferably includes two guide positioning rods, which are symmetrically distributed. At the same time, a plurality of positioning holes are respectively opened on the first layer 111, the reference workpiece 4, the second layer 112, the workpiece to be inspected 5 and the third layer 113. If the positioning is accurate, all the positioning holes at the same relative position can be located on the same axis.

[0046] Each guide positioning rod can vertically pass through the first layer 111, the reference part 4, the second layer 112 and the inspected part 5 in sequence to achieve guide positioning. If necessary, it can continue to pass through the inspected part 5 downward and then connect with the third layer 113.

[0047] The method of using the new surface trajectory detection equipment is as follows:

[0048] After the inspection of the current workpiece 5 is completed, the two guide positioning rods and the rotating assembly 2 are pulled upwards so that the rotating assembly 2 and the dial indicator 3 are out of the height range of the workpiece 5;

[0049] Then remove the inspected piece 5 from the main support 11 and put the next piece 5 into it;

[0050] Then align the positioning holes and insert the two guide positioning rods into the corresponding positioning holes of the test piece 5;

[0051] Then slowly lower the rotating assembly 2 and wait for the dial indicator 3 to enter the middle position of the curve of the test piece 5. During this process, the relative height of the rotating spindle 221 can be adjusted by the quick plug-in pin 223 so that the dial indicator 3 is at an appropriate height;

[0052] Then adjust the upper and lower dial indicators 3 so that their values ​​are consistent (return to zero);

[0053] Then slowly rotate the turntable 21 and observe the upper and lower dial indicators 3. If their values ​​are always synchronized, it means that the trajectories of the test piece 5 and the reference piece 4 are consistent, and the test piece 5 is a qualified product.

[0054] The rotating assembly 2 can drive the two dial indicators 3 to rotate synchronously during the rotation process. The two dial indicators 3 can compare and detect the inner wall curved surface of the reference part 4 and the inner wall curved surface of the test part 5 during the rotation process. If the values ​​of the two dial indicators 3 are always synchronized, it means that the trajectory of the test part 5 and the reference part 4 is consistent, and the test part 5 is a qualified product. If they are not synchronized, it is a failed product.

[0055] The new surface trajectory detection equipment has clearer detection logic, a simpler overall structure, and is simpler and faster to operate, which can effectively improve detection efficiency.

[0056] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
