Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] See also Figure 1-Figure 3 A CNC machining device for connector machining comprises a bottom plate 1, a discharge hole 12 is evenly penetrated on the top of the bottom plate 1, a discharge groove 13 is penetrated on the top of the bottom plate 1, an inverted V-shaped guard plate 5 is fixedly arranged in the discharge groove 13, two groups of internal thread sleeves 36 are evenly and slidably arranged in the discharge groove 13, an inverted V-groove is penetrated on the outer wall of the internal thread sleeve 36, the inverted V-shaped guard plate 5 is slidably arranged in the inverted V-groove, a bidirectional screw rod 24 is rotatably arranged in the discharge groove 13, the bidirectional screw rod 24 can be protected by the inverted V-shaped guard plate 5, so as to prevent the debris generated by machining from entering the discharge groove 13 and falling on the bidirectional screw rod 24, so as to ensure the reliability of the screw connection of the bidirectional screw rod 24 to the internal thread sleeve 36, the two groups of internal thread sleeves 36 are evenly screwed on the outer side of the bidirectional screw rod 24, the top of the internal thread sleeve 36 is connected with a clamping assembly, and the left side of the bidirectional screw rod 24 penetrates the left side of the bottom plate 1 and is connected with an adjusting assembly.
[0024] The clamping assembly includes a slider 3, which is fixedly arranged on the top of the internal threaded sleeve 36, and a group of square holes are opened on the opposite sides of the two groups of sliders 3, in which a magnetic block 35 is embedded, a square rod 33 is inserted in the square hole, and the outer wall of the square rod 33 is embedded with an iron block 34, and a group of clamping plates 31 are arranged on the opposite sides of the two groups of square rods 33, and a group of anti-skid pads 32 are fixedly arranged on the opposite sides of the two groups of clamping plates 31, and the magnetic block 35 and the iron block 34 are adsorbed on each other, and a gap is left between the magnetic block 35 and the iron block 34 so that they do not contact each other. The square rod 33 can be fixed in the square hole of the slider 3 by the mutual adsorption of the magnetic block 35 and the iron block 34, and then the clamping plate 31 can be fixed on the slider 3, and the clamping stability of the clamping plate 31 can be improved by the anti-skid pad 32, and at the same time, The clamping plate 31 and the slider 3 are connected by magnetic adsorption. Therefore, when facing connectors 4 of different shapes, the clamping plate 31 of different shapes can be quickly replaced by directly plugging and unplugging, thereby improving the adaptability of the device to connectors 4 of different shapes. Since there is a gap between the magnetic block 35 and the iron block 34, the pressure generated when the clamping plate 31 clamps the connector 4 will not cause the magnetic block 35 and the iron block 34 to contact each other, thereby preventing wear between the magnetic block 35 and the iron block 34, thereby effectively improving the service life of the magnetic block 35. Two sets of mounting sleeves 11 are evenly fixed on the front and rear sides of the base plate 1. Bolts are passed through the mounting sleeves 11 and are screwed to the threaded holes on the CNC machine tool, so that the device can be fixed on the CNC machine tool.
[0025] The adjusting assembly includes a worm gear 2, which is fixedly arranged on the left side of the bidirectional screw 24. A worm 21 is meshed at the bottom of the worm gear 2, and a handwheel 23 is fixedly arranged on the front side of the worm 21. Turning the handwheel 23 drives the worm gear 2 to rotate through the worm 21, thereby driving the bidirectional screw 24 to rotate, and the two groups of internal threaded sleeves 36 are driven to move inward synchronously through the bidirectional screw 24, thereby driving the clamping plate 31 on the internal threaded sleeve 36 to move synchronously to clamp the connector 4 in the center. The self-locking property of the worm 21 and the worm gear 2 can ensure the stability of the connector 4 after clamping, thereby ensuring the accuracy of the subsequent CNC machine tool processing of the connector 4. The outer wall of the worm 21 is evenly rotated with two groups of shaft seats 22, and the two groups of shaft seats 22 are evenly fixed on the left side of the base plate 1. The connector 4 is placed on the top of the base plate 1, and the connector 4 is located between the two groups of anti-slip pads 32.
[0026] Working principle: Use bolts to pass through the mounting sleeve 11 and screw them into the threaded holes on the CNC machine tool, so that the device can be fixed on the CNC machine tool. Turn the handwheel 23 to drive the worm wheel 2 to rotate through the worm 21, and then drive the bidirectional lead screw 24 to rotate. The two sets of internal thread sleeves 36 are driven to move inward synchronously through the bidirectional lead screw 24, and then the clamping plate 31 on the internal thread sleeve 36 is driven to move synchronously to clamp the connector 4 in the center. The self-locking property of the worm 21 and the worm wheel 2 can ensure the stability of the connector 4 after clamping, and thus ensure the accuracy of the subsequent CNC machine tool processing of the connector 4. The bidirectional lead screw 24 can be protected by the inverted V-shaped guard plate 5, so as to prevent the debris generated by the processing from entering the discharge trough 13 and falling onto the bidirectional lead screw 24, so as to ensure the bidirectional lead screw 24. To ensure the reliability of the screw connection of the internal threaded sleeve 36, the square rod 33 can be fixed in the square hole of the slider 3 through the mutual adsorption of the magnetic block 35 and the iron block 34, and then the clamping plate 31 can be fixed on the slider 3. The anti-slip pad 32 can improve the clamping stability of the clamping plate 31. At the same time, since the clamping plate 31 and the slider 3 are connected by magnetic adsorption, when facing connectors 4 of different shapes, the clamping plates 31 of different shapes can be quickly replaced by directly plugging and unplugging, thereby improving the adaptability of the device to connectors 4 of different shapes. Since there is a gap between the magnetic block 35 and the iron block 34, the pressure generated when the clamping plate 31 clamps the connector 4 will not cause the magnetic block 35 and the iron block 34 to contact each other, thereby preventing wear between the magnetic block 35 and the iron block 34, thereby effectively improving the service life of the magnetic block 35.
