[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0034] Refer to Figure 1 - Figure 2 and Figure 4, an embodiment provided by the present utility model: a ring-type automatic measuring machine, which includes a spindle base 1. A sliding module 2 is fixedly connected to the rear side of the top end of the spindle base 1. A clamp is arranged at the bottom end of the sliding module 2, and the clamp can move up and down. This is the prior art and will not be explained in detail here. A positioning mechanism 3 is arranged at the top end of the spindle base 1; through the setting of the positioning mechanism 3, the positioning control of ring-shaped workpieces of different sizes can be realized. The positioning mechanism 3 includes a support table 301, the shape of the support table 301 is an inverted T shape, a screen 304 is fixedly connected to the inner side wall of the support table 301, and the screen 304 is convenient for cooperating with the collection mechanism 4 mentioned later. A rotating column 307 is rotatably connected to the inner wall of the center of the support table 301. The top end of the rotating column 307 is rotatably connected to a connecting column 306. There are four groups of connecting columns 306 and they are all L-shaped. By rotating the rotating column 307, the four groups of connecting columns 306 are driven to move so as to achieve the purpose of approaching and clamping. One end of the connecting column 306 far from the rotating column 307 is rotatably connected to a positioning seat 305. The number of positioning seats 305 is the same as that of the connecting columns 306. The bottom end of the rotating column 307 is fixedly connected to a positioning column 310, and their rotation trajectories are the same. The bottom end of the positioning column 310 is rotatably connected to an adapter rod 308, and the adapter rod 308 plays a connecting role to avoid movement interference. And the initial state of the adapter rod 308 is Figure 4 state. The front end of the adapter rod 308 is rotatably connected to a movable column 303. By moving the movable column 303, the adapter rod 308 is driven to move. A fixed block 302 is fixedly connected to the front end of the support table 301. A latch 312 is elastically connected to the inner wall of the fixed block 302 through a connecting spring 311. An inclined surface is provided at the bottom end of the latch 312, and the inclined surface is arranged towards the rear end. The arrangement of the inclined surface can achieve the purpose of convenient movement. A collection mechanism 4 is arranged at the top end of the support table 301. Through the collection mechanism 4, the debris on some ring-shaped workpieces can be discharged and collected.

[0035] Refer to Figure 3 , Figure 5 and Figure 6, the bottom end of the support table 301 is fixedly connected to the top end of the main shaft base 1. It is fixedly arranged, and thus the support table 301 is supported by the main shaft base 1. The outer wall of the positioning seat 305 is slidably connected to the inner wall of the sieve 304. The setting of the sieve 304 can guide the positioning seat 305. The outer arc surface of the movable column 303 is slidably connected to the inner wall of the support table 301. The outer arc surface of the movable column 303 penetrates and is slidably connected to the first half part of the support table 301. The front end inner wall of the support table 301 is fixedly connected with an elastic telescopic rod 309. The elastic telescopic rod 309 is formed by two sets of sleeve rods sleeved with each other, and relative sliding can occur between them to change its overall length. In addition, a spring is built into the elastic telescopic rod 309 to make it have a certain elasticity. The rear end of the elastic telescopic rod 309 contacts the front end of the connecting rod 308. Through the elasticity of the elastic telescopic rod 309, the movable column 303 can have the function of quickly resetting. One end of the connecting spring 311 is fixedly connected to the outer wall of the plug pin 312, and the other end of the connecting spring 311 is fixedly connected to the inner wall of the fixed block 302. The outer wall of the plug pin 312 is slidably connected to the inner wall of the fixed block 302. The outer wall of the plug pin 312 penetrates and is slidably connected to the inner wall of the fixed block 302. The penetrating setting facilitates manual movement of the plug pin 312. The bottom end of the plug pin 312 is inserted into the top end of the movable column 303. Multiple insertion holes are opened at the top end of the movable column 303, and the bottom end of the plug pin 312 is inserted into the inner wall of the insertion hole.

[0036] Refer to Figure 2 - Figure 3 , the collection mechanism 4 includes a dust-proof cover 401. The bottom end inner wall of the dust-proof cover 401 is inserted into the top end of the support table 301. The dust-proof cover 401 can prevent dust from getting on the support table 301 when not in use. Connecting pipes 402 are fixedly connected to the left and right end inner walls of the support table 301 respectively. A guiding port 403 is fixedly connected to the top end of the connecting pipe 402. A vacuum cleaner can be arranged at the end of the connecting pipe 402 away from the support table 301 to suck away dust, iron filings and other waste chips. The guiding port 403 is in the shape of an inverted frustum. The inverted frustum shape can facilitate sucking away dust, iron filings and other waste chips from multiple places.

[0037] Working principle: When positioning annular workpieces of different sizes, first connect the outer end of the connecting pipe 402 to a vacuum cleaner. At this time, the annular workpiece can be placed above the screen 304 first, and then the movable column 303 is pulled forward. At this time, the movable column 303 will contact and squeeze the bottom inclined surface of the plug pin 312, so that the plug pin 312 moves upward. And when the movable column 303 moves forward, it will drive the connecting rod 308 and its positioning column 310 to move accordingly. And at this time, the rotating column 307 will rotate, so that multiple connecting columns 306 drive the positioning seat 305 to move closer to the middle, so as to position annular workpieces of different sizes. And when the movable column 303 moves forward, the front end of the connecting rod 308 will contact and squeeze the movable end of the elastic telescopic rod 309 at this time, so that the overall length of the elastic telescopic rod 309 changes. And when the positioning operation is completed, at this time, due to the elasticity of the connecting spring 311, the plug pin 312 is reset. Furthermore, the bottom end of the plug pin 312 is inserted and fixed with the movable column 303. Then the vacuum cleaner is started, so that the dust, iron filings and waste chips on the workpiece are sucked into the connecting pipe 402 through the guiding port 403. When the positioning seat 305 needs to be reset, at this time, the plug pin 312 is moved upward, and the limit of the plug pin 312 on the movable column 303 is released. Due to the elasticity of the elastic telescopic rod 309, the movable column 303 is reset, and multiple positioning seats 305 are also reset for the next clamping operation.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
