[0002] The rapid positioning and clamping mechanism is a type of rapid positioning and clamping mechanism used in ultra-precision lathes, mainly for the rapid positioning and clamping of workpieces. It is quite common in existing technologies.

[0003] Existing technologies, such as the utility model patent with publication number CN218224697U, disclose a clamping and positioning device for a horizontal lathe. This patent employs a clamping mechanism installed on a solid chuck and a positioning mechanism installed on the tailstock. A limiting sleeve in the clamping mechanism is fixed to a center plate at the center of the solid chuck, and the limiting sleeve is coaxial with the solid chuck. The positioning mechanism has a threaded disassembly sleeve at the end of a sleeve, with a center inside the sleeve, and the end of the disassembly sleeve abuts against the center. This effectively solves the axial movement problem that easily occurs during machining on horizontal lathes. Furthermore, by using self-made limiting sleeves of different lengths, it is possible to quickly achieve the positioning and clamping of machined parts, improving machining efficiency and product quality. The design of the disassembly sleeve allows for interchangeability between ordinary horizontal lathes and CNC horizontal lathes, reducing the cost and customization time associated with custom-made CNC horizontal lathe centers.

[0004] The inventors discovered in their daily work that existing clamping devices rely on manual rotation of a screw to clamp the workpiece, requiring repeated rotation to quickly secure it. This cumbersome method leads to low work efficiency. Utility Model Content

An mounting plate 211 is fixedly connected to the lower surface of the moving block 204. A cylinder 209 is fixedly connected to both sides of the fixed plate 202. A positioning plate 210 is fixedly connected to the output end of the cylinder 209. Two pressing plates 212 are fixedly connected to the side of the two positioning plates 210 that are close to each other. The inclined surface of the pressing plate 212 abuts against the inclined surface of the mounting plate 211. A compression spring 213 is provided between the side of the two moving blocks 204 that are close to each other and the limiting groove 203. The two ends of the compression spring 213 are fixedly connected to the moving block 204 and the limiting groove 203, respectively. When personnel need to clamp and fix the workpiece, the two cylinders 209 can be activated to move the two clamping plates 206 closer together, thereby quickly clamping the workpiece and improving personnel efficiency. A limiting post 207 is fixedly connected to the inner wall of the limiting groove 203, and the limiting post 207 is slidably connected to the moving block 204. The limiting post 207 can limit the moving block 204, preventing misalignment during sliding on the inner wall of the limiting groove 203.

[0033] In the embodiments of this utility model, please refer to Figure 4 and Figure 5The replacement structure 3 includes a positioning groove 301 and an auxiliary plate 303. The positioning groove 301 is formed on the movable plate 205. The auxiliary plate 303 is fixedly connected to the movable plate 205. A connecting plate 302 is slidably connected to the inner wall of the positioning groove 301. The connecting plate 302 is fixedly connected to the clamping plate 206. A baffle 305 is slidably connected to the inner wall of the auxiliary plate 303. An auxiliary groove 304 is formed on the inner wall of the auxiliary plate 303. A connecting plate 309 is slidably connected to the inner wall of the auxiliary groove 304. The connecting plate 309 is fixedly connected to the baffle 305. A fixing block 306 is fixedly connected to the upper surface of the auxiliary plate 303. A spring 308 is provided on the side of the fixing block 306 and the connecting plate 309 that are close to each other. The two ends of the spring 308 are fixedly connected to the fixing block 306 and the connecting plate 309, respectively. When personnel need to change clamping plates 206 to clamp workpieces of different shapes, they can move the connecting plate 309 to move the baffle 305 away from the upper surface of the connecting plate 302, and then move the clamping plate 206 until the connecting plate 302 slides out of the inner wall of the positioning groove 301.

A telescopic rod 307 is fixedly connected to the side of the fixing block 306 near the connecting plate 309, and a spring 308 is sleeved on the arc surface of the telescopic rod 307. The telescopic rod 307 can limit the spring 308, preventing deformation of the spring 308 during short-term use. Several anti-slip grooves 310 are evenly distributed on the inner wall of the connecting plate 309. The anti-slip grooves 310 increase the friction between the personnel's hands and the connecting plate 309, preventing slippage during movement of the connecting plate 309.

[0034] The working principle of the rapid positioning and clamping mechanism for an ultra-precision lathe provided by this utility model is as follows: When a worker needs to clamp a workpiece, the worker can first move the workpiece so that it is placed between two clamping plates 206. Then, the worker activates two cylinders 209. The output end of the cylinders 209 drives the positioning plate 210 to move downward. The two positioning plates 210 drive the two pressing plates 212 to move downward. The pressing plates 212 are made of stainless steel, which has high strength and good wear resistance, preventing deformation of the pressing plates 212 during short-term use. Then, the two pressing plates 212 drive the mounting plates 211 to move closer to each other. The mounting plates 211 drive the moving block 204. The moving block 204 slides on the arc surface of the limiting post 207 as it moves closer to the workpiece. The limiting post 207 can limit the moving block 204 and prevent it from misaligning during sliding on the inner wall of the limiting groove 203. Then, the moving block 204 drives the moving plate 205 and the protective pad 208 to move closer to the workpiece. The protective pad 208 can protect the moving block 204 and prevent the side of the two moving blocks 204 that is far away from each other from contacting the limiting groove 203. Then, the moving block 204 also drives the compression spring 213 to rewind. The moving plate 205 drives the clamping plate 206 to move closer to the workpiece with the help of the changing structure 3 until the two clamping plates 206 abut against the workpiece.

[0035] Additionally, when personnel need to change the clamping plate 206 to clamp workpieces of different shapes, they can first move the connecting plate 309 towards the fixed block 306. The anti-slip groove 310 on the inner wall of the connecting plate 309 increases the friction between the personnel's hands and the connecting plate 309, preventing slippage during movement. Then, the connecting plate 309 moves the output end of the baffle 305 and the telescopic rod 307 towards the fixed block 306. The spring 308 moves towards the fixed block 306, where the telescopic rod 307 can limit the spring 308 to prevent deformation during short-term use. Then, the connecting plate 309 also drives the spring 308 to retract until the baffle 305 is completely away from the upper surface of the connecting plate 302. Then, the personnel move the clamping plate 206 to move it upward. The clamping plate 206 drives the connecting plate 302 to move upward until the connecting plate 302 slides out of the inner wall of the positioning groove 301.

[0036] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
