[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] like Figure 1-8 As shown, the embodiments of the present invention provide;

[0042] A precision mechanical positioning device based on spatial geometric transformation, comprising a fixing component 1 and two supporting components 2, wherein the upper parts of adjacent ends of the two supporting components 2 are each provided with a connecting component 3, the fixing component 1 comprises a bottom plate 101, the supporting component 2 comprises a supporting plate 201, and the connecting component 3 comprises a connecting plate 301;

[0043] Both ends of one side of the upper surface of the bottom plate 101 are fixedly connected with mounting seats 102, the inner wall of the mounting seats 102 is fixedly connected with an electric telescopic rod 103, the output end of the electric telescopic rod 103 is fixedly connected to the outer wall of the adjacent support plate 201 on the other side, and the middle part of the adjacent end of the outer wall of the two support plates 201 is provided with a connecting groove 203, and the inner bottom surface of the connecting groove 203 is rotatably connected with a threaded rod 206;

[0044] The rod bodies of the threaded rods 206 are all sleeved with threaded sleeves 204, the middle part of the upper surface of the connecting plate 301 is fixedly connected with a placement plate 307, both sides of the upper surface of the placement plate 307 are fixedly connected with cylinders 306, the output ends of the cylinders 306 are fixedly connected with connecting frames 305, both sides of the upper lower end of the connecting frame 305 are fixedly connected with stabilizing frames 308, and one end of the stabilizing frame 308 close to the center of the connecting plate 301 is fixedly connected with a positioning block 309;

[0045] By starting the electric telescopic rod 103 through the control panel 202, the horizontal position of the support plate 201 can be adjusted, providing basic horizontal adjustment for the overall positioning. The synchronous motor 205 drives the threaded rod 206 to rotate, driving the threaded sleeve 204 and the connecting plate 301 to achieve vertical displacement adjustment. Due to the high precision of the motor and thread transmission, more precise height adjustment can be achieved, and the cylinder 306 drives the connecting frame 305, the stabilizing frame 308, the positioning block 309 and the positioning plate 310 to move in the plane direction. In conjunction with the laser displacement sensor 303 under the positioning plate 310, the position information can be fed back in real time, thereby calibrating the position of the target object in three-dimensional space to ensure that the positioning accuracy reaches a high level to meet the requirements of mechanical positioning.

[0046] The adjacent ends of the positioning blocks 309 are fixedly connected to the positioning plates 310, the output ends of the two cylinders 306 are located at the opposite ends, and the center of the lower surface of the positioning plate 310 is fixedly connected to the laser displacement sensor 303. The laser displacement sensor 303 is installed at the center of the lower surface of the positioning plate 310, and can measure the distance and position relationship between the positioning plate 310 and the target object in real time, providing accurate position feedback information for the entire positioning process.

[0047] Slide grooves 104 are provided at both ends of the other side of the upper surface of the base plate 101, and the lower ends of the outer walls of the support plate 201 are slidably connected to the inner walls of the slide grooves 104. The support plate 201 can slide smoothly along the slide grooves 104, so that the electric telescopic rod 103 can move more smoothly and stably when pushing the support plate 201 for horizontal displacement. The inner top surface of the connecting groove 203 is fixedly connected with a synchronous motor 205, and the output ends of the synchronous motor 205 are fixedly connected to the upper ends of the threaded rods 206. The synchronous motor 205 can control the rotation of the threaded rods 206, so that the threaded sleeve 204 drives the connecting plate 301 to achieve high-precision displacement adjustment in the vertical direction.

[0048] A control panel 202 is provided on the upper part of the front end of the outer wall of the front support plate 201. Both ends of the outer wall of the connecting plate 301 slide with the corresponding inner walls of the connecting grooves 203 and are fixedly connected with the corresponding threaded sleeves 204. The operator can control the entire device conveniently and quickly through the control panel 202, and can flexibly adjust the actions of each component according to the actual positioning task. Moving grooves 302 are opened in the middle of both sides of the outer wall of the connecting plate 301, and the middle of one side of the outer wall of the connecting frame 305 close to the center of the placement plate 307 is slidably connected with the inner wall of the corresponding moving groove 302. The cooperation between the moving groove 302 and the connecting frame 305 can effectively guide the moving direction of the connecting frame 305, so that under the drive of the cylinder 306, it can more smoothly and accurately drive the stabilizing frame 308, the positioning block 309 and the positioning plate 310 to move in the plane direction.

[0049] Limiting grooves 304 are provided on both sides of the lower end of the connecting plate 301, and the upper ends of the positioning blocks 309 are slidably connected to the inner walls of the corresponding limiting grooves 304. The limiting grooves 304 have a good limiting effect on the positioning blocks 309, so that the positioning blocks 309 can only move along the direction of the limiting grooves 304 during movement, thereby avoiding displacement or shaking of the positioning blocks 309 during movement.

[0050] Working principle: The control panel 202 serves as the control center, through which the operator issues instructions to the device to start the entire positioning process. When the control panel 202 issues an instruction, the two electric telescopic rods 103 start working. The electric telescopic rods 103 are fixed on the mounting seat 102, and the mounting seat 102 is fixed on both ends of one side of the upper surface of the bottom plate 101. The output end of the electric telescopic rod 103 is connected to the outer wall of the support plate 201 on the other side. Through the telescopic action of the electric telescopic rod 103, the corresponding support plate 201 is driven to move on both sides in the horizontal direction, thereby adjusting the horizontal span of the device to adapt to different work requirements or the position of the target object;

[0051] After the support plate 201 completes the horizontal displacement adjustment, the synchronous motor 205 starts to work. The synchronous motor 205 is fixed to the inner top surface of the connecting groove 203, and its output end is connected to the upper end of the threaded rod 206. When the synchronous motor 205 is started, it drives the threaded rod 206 to rotate. Since the rod body of the threaded rod 206 is sleeved with a threaded sleeve 204, and the threaded sleeve 204 is fixedly connected to the connecting plate 301, and the two ends of the outer wall of the connecting plate 301 are slidably connected to the inner wall of the connecting groove 203, the rotation of the threaded rod 206 causes the threaded sleeve 204 to move up and down along the threaded rod 206, thereby driving the connecting plate 301 to move in the vertical direction, so as to achieve the height adjustment of the placement plate 307 placed on the connecting plate 301;

[0052] After the connecting plate 301 completes the vertical displacement adjustment, the cylinder 306 starts to work. The two cylinders 306 are respectively fixed on both sides of the upper surface of the placement plate 307, and the output ends are located at the opposite ends. When the cylinder 306 is started, its output end drives the connecting frame 305 to move. The middle part of the outer wall of the connecting frame 305 close to the center of the placement plate 307 is slidably connected to the inner walls of the moving grooves 302 opened on both sides of the outer wall of the connecting plate 301 to ensure the stability of the movement of the connecting frame 305. The stabilizing frame 308 fixedly connected on both sides of the upper part of the lower end of the connecting frame 305 will move with the movement of the connecting frame 305, thereby driving the positioning block 309 fixedly connected at one end of the stabilizing frame 308 to move. Since the upper end of the positioning block 309 is slidably connected to the inner walls of the limiting grooves 304 opened on both sides of the lower end of the connecting plate 301, the movement of the positioning block 309 will drive the positioning plate 310 fixed at its adjacent end to move in the front and rear directions.

[0053] A laser displacement sensor 303 is fixedly connected at the center of the lower surface of the positioning plate 310. During the movement of the positioning plate 310, the laser displacement sensor 303 can measure the distance and positional relationship between the positioning plate 310 and the target object in real time. By continuously adjusting the positions of each component and utilizing the information fed back by the laser displacement sensor 303, the positioning of the target object in three-dimensional space is ultimately achieved.
