DETAILED DESCRIPTION

[0027] The present invention is further described below in conjunction with specific embodiments. However, people familiar with the art should understand that the detailed description given here in conjunction with the drawings is for better explanation, and the structure of the present invention necessarily exceeds these limited embodiments. For some equivalent replacement schemes or common means, they are no longer described in detail herein, but still fall within the scope of protection of the present application.

[0028] Figures 1 to 6 It is the best embodiment of the utility model, and the following Figures 1 to 6 The utility model is further described.

[0029] like Figures 1 to 6 As shown, a CNC automatic machining positioning device comprises: a fixed plate 1; a support component 2, which is arranged on the outside of the fixed plate 1 and is used to provide support for the workpiece; a clamping component 4, which is arranged on the outside of the support component 2 and is used to fix the position of the workpiece; a control component 3, which is arranged inside the support component 2 and is used to control the clamping component 4. Specifically, when in use, the fixed plate 1 is first connected to the machine tool, and after the connection is completed, the workpiece to be processed is positioned through the support component 2, and then the positioned workpiece is clamped through the cooperation of the clamping component 4 and the control component 3 to avoid force deviation during the machining process and ensure stability during use.

[0030] like Figures 1 to 6As shown, the support assembly 2 includes a support block 201 and a positioning block 204. The support block 201 is arranged on a first plane of the fixed plate 1, and the first plane is the contact surface between the support block 201 and the fixed plate 1. A plurality of sliding grooves 202 are arranged on the top of the support block 201, and a through groove 203 is arranged inside the sliding grooves 202. A cavity is opened inside the support block 201, and the cavity is connected with the through groove 203. The positioning block 204 is arranged on the top of the support block 201, and a plurality of connecting blocks are arranged at the bottom of the positioning block 204. The connecting blocks slide inside the sliding grooves 202, so that the position of the positioning block 204 can be adjusted. At the same time, the appropriate positioning block 204 can be selected according to the size of the workpiece to ensure that the workpiece is positioned accurately.

[0031] like Figures 1 to 6 As shown, a plurality of mounting holes are provided on the outer side of the positioning block 204. During processing, positioning pins can be installed through the mounting holes to further determine the placement of the workpiece, thereby ensuring the accuracy of the workpiece position during processing.

[0032] like Figures 1 to 6 As shown, the clamping assembly 4 includes a plurality of support columns 401, a sliding column 402, a pressure plate 404 and a connecting member 5. The connecting member 5 is adapted to the sliding groove 202. The support column 401 is connected to the connecting member 5. A groove 406 is provided inside the support column 401. The groove 406 runs through the top of the support column 401. The sliding column 402 slides inside the groove 406. The sliding column 402 is arranged on the top of the pressure plate 404. The groove 406 guides the sliding column 402 to ensure the accuracy of the direction of the sliding column 402 during movement. At the same time, the support column 401 provides support for the sliding column 402 to ensure stability during clamping. When clamping the workpiece, the sliding column 402 is first driven to move by the control assembly 3. While moving, the workpiece is pressed and fixed by the pressure plate 404 to avoid displacement of the workpiece due to force during processing.

[0033] like Figures 1 to 6 As shown, a plurality of guide grooves 403 are provided on the outside of the sliding column 402, a guide block 405 slides inside the guide groove 403, and the guide block 405 is connected to the support column 401, and the guide groove 403 is composed of a spiral groove and a straight groove, so that during the movement of the sliding column 402, the sliding column 402 is guided to rotate through the cooperation of the guide block 405 and the guide groove 403, avoiding interference between the pressure plate 404 and the workpiece during the installation of the workpiece, thereby ensuring stability during use.

[0034] More specifically, when the sliding column 402 moves upward, the guide block 405 slides inside the guide groove 403 relative to the sliding column 402. When the guide block 405 moves to the spiral groove end of the guide groove 403, since the guide block 405 is fixed to the support column 401, the guide block 405 drives the sliding column 402 and the pressure plate 404 to rotate through the spiral groove, so that the pressure plate 404 rotates to one side to avoid interference with the pressure plate 404 when installing and taking the workpiece. When the workpiece is placed, the sliding column 402 is first pulled downward by the control component 3. While moving downward, the pressure plate 404 is driven to rotate to the top of the workpiece through the cooperation of the spiral groove and the guide block 405. When the guide block 405 moves to the straight groove section, the pressure plate 404 and the sliding column 402 are guided to move in a straight line through the cooperation of the guide block 405 and the straight groove, so that the workpiece is pressed and fixed, ensuring the stability of the workpiece during processing.

[0035] like Figures 1 to 6 As shown, the connecting member 5 includes a sliding block 501, which slides inside the sliding groove 202. A plurality of bolts 502 are arranged inside the sliding block 501, and a clamping plate 503 is arranged on the outside of the bolts 502. The sliding block 501 has the same shape as the sliding groove 202. The sliding block 501 and the support block 201 are fixed by squeezing the clamping plate 503 by the bolts 502. At the same time, the limitation of the sliding block 501 is released by the bolts 502 and the clamping plate 503, so that the position of the support column 401 can be adjusted according to the needs, thereby ensuring the flexibility when fixing the workpiece.

[0036] like Figures 1 to 6 As shown, the control assembly 3 includes a connecting plate 302, a telescopic member 301, a plurality of connecting rods 305 and a nut 306. The connecting plate 302 slides in the cavity. The telescopic member 301 is arranged at the bottom of the connecting plate 302, and the telescopic member 301 is connected to the support block 201. A plurality of threaded holes 303 are arranged on the top of the connecting plate 302. The connecting rod 305 is connected to the threaded holes 303, and the connecting rod 305 corresponds to the sliding column 402. The nut 306 is arranged at one end of the connecting rod 305. A limit plate 307 is also arranged on the outside of the connecting rod 305. The limit plate 307 is inside the groove 406. Sliding, both ends of the connecting rod 305 are respectively provided with external threads, so that the connecting rod 305 is connected to the nut 306 and the threaded hole 303 respectively, the connecting rod 305 passes through the sliding block 501, and the connecting rod 305 slides in the through groove 203, the telescopic member 301 can be a hydraulic telescopic rod, an air telescopic rod or an electric telescopic rod, etc. When in use, the connecting plate 302 is driven to move by the telescopic member 301. Since multiple connecting rods 305 are arranged on the connecting plate 302, when the connecting plate 302 moves, the multiple connecting rods 305 are driven to control the sliding column 402 to move at the same time.

[0037] More specifically, the limiting plate 307 provides support for the bottom of the sliding column 402, so that the sliding column 402 moves along with the connecting rod 305 under the clamping of the nut 306 and the limiting plate 307, thereby ensuring stability during use.
