[0002] Mechanical processing refers to the process of changing the size or performance of a workpiece through a mechanical device. It can be divided into cutting processing and pressure processing according to the difference in processing methods. When machining a workpiece, the workpiece needs to be placed on a processing table. Some workpieces may need to be processed on the other side due to processing requirements. When processing the other side of the workpiece, the existing processing table mostly needs to disassemble the workpiece many times and then adjust the position of the workpiece. This processing method not only increases the labor intensity of workers, but also reduces the efficiency of workpiece processing;

The workpiece can be flipped without disassembling the workpiece for repositioning. At the same time, the workpiece can be positioned and fixed after flipping, which reduces the number of times workers adjust the workpiece and improves the processing efficiency of CNC machine tools.

[0004] Although the above patent can flip the workpiece without disassembling and repositioning the workpiece, and can position and fix the workpiece after flipping, from a practical point of view, due to the setting of the strip groove and the connection between the strip groove and the inner cavity of the base, the debris generated during the workpiece processing can easily enter the inner cavity of the base through the strip groove, which is not only inconvenient for manual cleaning, but the entry of impurities will also affect the transmission effect of the threaded rod on the threaded tube.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is: a tool fixture with a rotating positioning structure, comprising a base, a fixed plate vertically fixed to one side of the top surface of the base, and a movable plate slidably arranged on the other side of the top surface of the base, the movable plate is vertically rotatably connected to a rotating rod on one side corresponding to the fixed plate, a clamping plate is fixed to the end of the rotating rod, a first motor is installed on the side of the fixed plate away from the rotating rod, the output shaft of the first motor rotates through the fixed plate and is fixedly connected to one of the rotating rods, a slideway is horizontally opened on one side of the base, a driving mechanism for providing sliding force for the movable plate is arranged in the slideway, and a dumping mechanism for cleaning debris after processing is also arranged on the base;

[0007] The driving mechanism includes a screw rod that is laterally rotatably arranged between the inner walls on both sides of the slideway and a movable frame that is L-shaped and threadedly connected to the screw rod. A bearing rod is fixed to the top of the movable frame. The movable plate is vertically fixed to the top surface of the bearing rod. The bearing rod and the movable frame form a C-shaped frame as a whole.

[0008] The tilting mechanism includes a tilting plate obliquely arranged on the inner side of the C-shaped frame and a support rod fixedly sleeved on the lowest end of the tilting plate, the support rod is rotatably connected to the fixed plate, a movable groove is horizontally opened on the top surface of the base, a push-pull component is arranged in the movable groove, and a touch component cooperating with the push-pull component is arranged on one side of the movable frame.

[0020] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0021] Reference Figure 1-3 As shown, a fixture with a rotating positioning structure comprises a base 1, a fixed plate 2 vertically fixed to one side of the top surface of the base 1, and a movable plate 3 slidably arranged on the other side of the top surface of the base 1, the movable plate 3 is vertically rotatably connected with a rotating rod 4 on one side corresponding to the fixed plate 2, a clamping plate 5 is fixed to the end of the rotating rod 4, a first motor 6 is installed on the side of the fixed plate 2 away from the rotating rod 4, and the output shaft of the first motor 6 rotates through the fixed plate 2 and is fixedly connected to one of the rotating rods 4;

[0022] When in use, the workpiece to be processed is placed horizontally between the movable plate 3 and the fixed plate 2 in advance, and one side of the workpiece is pressed against the clamping plate 5 on the fixed plate 2, and then the movable plate 3 is slid toward the workpiece until the clamping plate 5 on the movable plate 3 presses against the other side of the workpiece, so that the movable plate 3 and the clamping plate 5 on the fixed plate 2 cooperate to clamp the workpiece, thereby ensuring the stability of the workpiece during surface processing;

[0023] After one side of the workpiece is processed, the first motor 6 is turned on, and the output shaft of the first motor 6 drives one of the rotating rods 4 and the clamping plate 5 to rotate, so that the workpiece can be turned over without disassembling and repositioning the workpiece.

[0024] Further, refer to Figure 1 As shown, it is worth noting that a slideway 7 is transversely provided on one side of the base 1, and a driving mechanism for providing a sliding force for the movable plate 3 is provided in the slideway 7;

[0025] The driving mechanism includes a screw rod 8 which is rotatably arranged between the inner walls of both sides of the slideway 7 and a movable frame 9 which is L-shaped and threadedly connected to the rod of the screw rod 8. A load-bearing rod 10 is fixed to the top of the movable frame 9. The movable plate 3 is vertically fixed to the top surface of the load-bearing rod 10. The load-bearing rod 10 and the movable frame 9 form a C-shaped frame as a whole.

[0026] A second motor 11 is installed at one end of the base 1, and the output shaft of the second motor 11 rotates and penetrates into the slideway 7 and is fixedly connected to one end of the screw rod 8;

[0027] By setting the slide 7 and the driving mechanism, the second motor 11 is turned on, and the screw 8 can use the threaded structure to drive the movable frame 9 during the rotation process, so that the movable frame 9 slides inside the slide 7, and provides power for the load-bearing rod 10 and the movable plate 3. In this way, without affecting the mobility of the movable plate 3, the setting of the slide 7 on the side of the base 1 can effectively protect the screw 8 from impurities, thereby preventing impurities generated during processing from falling into the slide 7 and affecting the use effect of the screw 8.

[0028] Further, refer to Figure 1-3 As shown, it is worth noting that the base 1 is also provided with a dumping mechanism for cleaning the debris after processing;

[0029] The tilting mechanism includes a tilting plate 12 obliquely arranged on the inner side of the C-shaped frame and a support rod 13 fixedly sleeved on the lowest end of the tilting plate 12, the support rod 13 is rotatably connected to the fixed plate 2, a movable groove 14 is horizontally opened on the top surface of the base 1, a push-pull component is arranged in the movable groove 14, and a touch component cooperating with the push-pull component is arranged on one side of the movable frame 9;

[0030] Through the setting of the tipping mechanism, when the driving mechanism is used to act on the movable plate 3 to slide from one side to the other side to clamp the workpiece, the push-pull component acts on the tilting plate 12 to turn it to a horizontal state, so that the debris generated by the processing can be accumulated on the surface of the tilting plate 12 and received by the tilting plate 12. After the processing is completed, when the movable plate 3 is reset and slides to the initial position, the trigger component acts on the push-pull component to push the tilting plate 12 to an inclined state, so that impurities automatically slide down under the slope of the tilting plate 12, and then the impurities are automatically processed, which is convenient for manual operation.

[0031] Further, refer to Figure 3 As shown, it is worth noting that the push-pull component includes a movable block 15 slidably arranged in the movable groove 14, a push-pull rod 16 is hinged between the movable block 15 and the tilting plate 12, a spring 17 is fixed between one side of the movable block 15 and the inner wall of one side of the movable groove 14, a magnetic plate is fixed on the other side of the movable block 15, and an electromagnet 18 matching the magnetic plate is installed on the inner wall of the other side of the movable groove 14;

[0032] The triggering component includes a mounting plate 19 vertically fixed to the side wall of the base 1, and a pressure sensor 20 abutting against the movable frame 9 is mounted on one surface of the mounting plate 19. A controller is also mounted on the base 1, and the pressure sensor 20 and the electromagnet 18 are both electrically connected to the controller;

[0033] After the processing is completed, when the movable plate 3 is reset and slid to the initial position, the movable frame 9 can contact the pressure sensor 20 to squeeze the pressure sensor 20, so that the pressure sensor 20 senses the pressure and transmits the pressure signal to the controller. The controller turns on the electromagnet 18, so that the electromagnet 18 forms a strong repulsive force on the magnetic plate on the movable block 15, and then the movable block 15 is pushed to slide inside the movable groove 14 and compress the spring 17 to deform. During the sliding process of the movable block 15, the push-pull rod 16 can push the tilting plate 12, so that the tilting plate 12 is forced to flip to a tilted state;

[0034] On the contrary, when the driving mechanism is used to slide the movable plate 3 from one side to the other side to clamp the workpiece, the movable frame 9 is separated from the pressure sensor 20, and the pressure on the pressure sensor 20 disappears. Similarly, the controller turns off the electromagnet 18, so that the repulsive force between the electromagnet 18 and the magnetic plate disappears, and then the movable block 15 can quickly reset and slide under the elastic force of the spring 17. Similarly, the push-pull rod 16 is used to pull the tilting plate 12 back to a horizontal state.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected.
