Because the old clamping plates or fixing parts need to be removed each time, and then new clamping plates or fixing parts are selected according to the diameter and arc size of the parts, and then the new clamping plates or fixing parts are installed on the corresponding parts of the lathe for positioning and clamping. The overall operation is relatively cumbersome, which will also affect the actual processing efficiency accordingly.

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The present application embodiment discloses a positioning tool for a mechanical parts processing lathe. Figure 1-3A positioning tool for a mechanical parts processing lathe comprises a lathe body 1, a fixing frame 2 is fixedly connected to the bottom of the inner cavity of the lathe body 1 by bolts, a control box 6 is fixedly connected to one side of the fixing frame 2 by bolts, two groups of sliding rods 4 are fixedly connected to the inner cavity side wall of the fixing frame 2 by bolts, two groups of sliding frames 5 are slidably connected to the inner cavity side walls of the two groups of sliding rods 4, the inner cavity side walls of the two groups of sliding frames 5 are both rotatably connected to the fixing rods 10 through a rotating shaft, the bottoms of the two groups of fixing rods 10 are fixedly connected to the first arc-shaped clamping plate 11 and the second arc-shaped clamping plate 17 by bolts, and the inner cavity side walls of the first arc-shaped clamping plate 11 and the second arc-shaped clamping plate 17 are fixedly connected to elastic anti-slip pads 12. The tops of the two sets of fixed rods 10 are provided with a first driving member for driving the fixed rods 10 and the first arc-shaped clamping plate 11 and the second arc-shaped clamping plate 17 at the bottom thereof to rotate, and the first driving member is arranged at the top of the sliding frame 5. The inner cavity side walls of the two sets of sliding frames 5 are threadedly connected with two sets of bidirectional screw rods 3. One end of the two sets of bidirectional screw rods 3 is rotatably connected to the inner cavity side wall of the fixed frame 2 through a rotating shaft. The other ends of the two sets of bidirectional screw rods 3 are rotated through the fixed frame 2 and extend to the inside of the control box 6. One end of the two sets of bidirectional screw rods 3 passing through the fixed frame 2 is provided with a second driving member for driving the bidirectional screw rods 3 to rotate, and the second driving member is arranged inside the control box 6;

[0020] By adopting the above technical scheme, the first driving member provided on the top of the two groups of sliding frames 5 is used for transmission, which can drive the two groups of fixing rods 10 to rotate, thereby driving the first arc clamping plate 11 and the second arc clamping plate 17 at the bottom to rotate. The corresponding clamping plate can be selected for use according to the size of the parts, and the elastic anti-skid pad 12 provided in the clamping plate can not only improve the anti-skid performance during the clamping process, but also avoid excessive clamping force causing wear on the surface of the parts. When the clamping plate is adjusted and switched, it can be rotated by the second driving member provided in the control box 6, thereby driving the two groups of bidirectional screw rods 3 in the fixed frame 2 to rotate. Since the surface of the bidirectional screw rod 3 is provided with two groups of opposite thread patterns, the two groups of sliding frames 5 threadedly connected on the surface and their corresponding components can be driven to move inward or outward at the same time. With the switched clamping plate, the parts can be positioned, clamped and fixed, and the stability of the sliding frame 5 during the movement and the clamping of the parts by the clamping plate can be improved by the provided sliding rod 4.

[0021] Reference Figure 1 and Figure 2The first driving member includes a first motor 7, a worm 8 and a worm wheel 9. The tops of the two groups of sliding frames 5 are fixedly connected to the first motor 7 by bolts. The two groups of first motors 7 are fixedly connected to the worm 8 through the output shaft. The end of the worm 8 away from the first motor 7 is rotatably connected to the inner cavity side wall of the sliding frame 5 through a rotating shaft. The surface of the worm 8 is meshed with the worm wheel 9. The bottom of the worm wheel 9 is fixedly connected to the top of the fixed rod 10 by bolts. The second driving member includes a second motor 13, a first toothed belt pulley 14, a second toothed belt pulley 15 and a synchronous toothed belt 16. The bottom of the inner cavity of the control box 6 is fixedly connected to the second motor 13 by bolts. The second motor 13 is fixedly connected to the first toothed belt pulley 14 through the output shaft. The first toothed belt pulley 14 is meshed with the second toothed belt pulley 15 through the synchronous toothed belt 16. One side of the first toothed belt pulley 14 and the second toothed belt pulley 15 are fixedly connected to one end of the bidirectional screw 3 passing through the fixed frame 2 by bolts.

[0022] By adopting the above technical solution, the output of the two sets of first motors 7 can drive the worm 8 to rotate, so that the worm wheel 9 meshingly connected to the surface of the worm 8 can drive the fixed rod 10 to rotate, and the output of the second motor 13 can drive the first toothed pulley 14 to rotate, so that the second toothed pulley 15 can be driven to rotate synchronously through the synchronous toothed belt 16, thereby driving the two sets of bidirectional screws 3 to rotate.

[0023] The implementation principle of a positioning tool for a mechanical parts processing lathe in the embodiment of the present application is as follows: the output is obtained by two sets of first motors 7, which can drive the worm 8 to rotate, so that the worm wheel 9 meshingly connected to the surface of the worm 8 can drive the fixing rod 10 to rotate, thereby driving the first arc-shaped clamping plate 11 and the second arc-shaped clamping plate 17 at the bottom thereof to rotate. The corresponding clamping plate can be selected for use according to the size of the parts, and the elastic anti-skid pad 12 provided in the clamping plate can not only improve the anti-skid performance during the clamping process, but also avoid excessive clamping force causing wear on the surface of the parts. When the clamping plate is adjusted and switched, the output can be obtained by the second motor 13 The first toothed belt wheel 14 can be driven to rotate, and the second toothed belt wheel 15 can be driven to rotate synchronously through the synchronous toothed belt 16, so that the two sets of bidirectional screws 3 can be driven to rotate. Since the surface of the bidirectional screw 3 is provided with two sets of opposite thread patterns, the two sets of sliding frames 5 and their corresponding components connected by threads on the surface can be driven to move inward or outward at the same time. With the switched clamping plate, the parts can be positioned, clamped and fixed, and the stability of the sliding frame 5 during the movement and the clamping process of the parts can be improved by the provided sliding rod 4. The first motor 7 and the second motor 13 can be NEMA 17 stepper motor, NEMA 17 stepper motor is a synchronous motor, which controls the movement of the rotor by applying a pulse signal. The rotation angle of the stepper motor is usually controlled by controlling the number of input pulses. Each time a pulse signal is received, the stepper motor will rotate a fixed angle, which is called the step angle. The rotation direction of the stepper motor is determined by the sequence of the input pulse signals and the direction of the current. The forward and reverse rotation of the motor can be achieved by controlling the pulse sequence and the current direction, so that the first motor 7 and the second motor 13 can be used to conveniently switch the clamp and drive the clamp to move, and the corresponding parts can be positioned, clamped and fixed. The overall operation is simple, and the corresponding clamp can be quickly switched according to the arc parts of different diameters and radians to position, clamp and fix them, which can further improve the actual processing efficiency.
