DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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] like Figure 1-4As shown, the utility model provides a technical solution: a positioning device for a CNC lathe, comprising a base plate 1, the top of the base plate 1 is respectively connected to the bottom of a first vertical plate 2 and the bottom of a second vertical plate 3, the inner wall of the first vertical plate 2 is rotatably connected to the outer wall of a rotating shaft 4, the outer wall of the rotating shaft 4 is connected to the inner wall of a gear 5, the gear 5 is meshed with a rack 6, the side of the rack 6 is connected to a side corresponding to a connecting block 7, one end of the connecting block 7 is connected to an output end of a first electric telescopic rod 8, the outer wall of the first electric telescopic rod 8 is connected to the inner wall of a mounting plate 9, the side of the mounting plate 9 is connected to a side corresponding to the first vertical plate 2, a second electric telescopic rod 10 is arranged in the second vertical plate 3, and the ends of the rotating shaft 4 opposite to the second electric telescopic rod 10 are fixedly connected to a first clamping plate 11, the side of the second vertical plate 3 is connected to the side corresponding to the mounting frame 12, and the side of the mounting frame 12 is connected to the side corresponding to the bearing seat 14. A bearing 13 is arranged in the bearing seat 14, and the bearing seat 14 is rotatably connected to the second electric telescopic rod 10 through the bearing 13. By arranging the bearing 13 and the bearing seat 14, the second electric telescopic rod 10 can play a role of limiting and supporting during the rotation process, so as to avoid the second electric telescopic rod 10 from shaking during the rotation process and affecting its transmission effect. At the same time, the friction force generated when the second electric telescopic rod 10 rotates can be reduced to ensure its rotation accuracy and thus ensure its rotation stability. The side of the first vertical plate 2 is connected to the side corresponding to the guide plate 15, and the inner wall of the guide plate 15 is slidably connected to the outer wall of the slide plate 16. Then, the side of the slide plate 16 is connected to the side corresponding to the rack 6. By setting the slide plate 16 and the guide plate 15, it can play a guiding and limiting role in the movement of the rack 6, thereby preventing the rack 6 from being offset during the movement and causing it to be unable to engage with the gear 5. A slide groove 17 is provided on the opposite side of the first vertical plate 2 and the second vertical plate 3. The first vertical plate 2 is slidably connected to the two sliders 18 through the slide groove 17, and the second vertical plate 3 is slidably connected to the two guide blocks 19 through the slide groove 17. The side of the slider 18 opposite to the guide block 19 is connected to the two sides of the same second clamping plate 28. The clamping end of the second clamping plate 28 is provided with a buffer pad. The inner walls of the two sliders 18 are threadedly connected to the outer wall of the same bidirectional screw rod 20. The bidirectional screw One end of the rod 20 is connected to the output end of the motor 21, the bottom of the motor 21 is connected to the top of the mounting seat 22, and one end of the mounting seat 22 is connected to the corresponding end of the first vertical plate 2. By setting the slider 18, the guide block 19, the bidirectional screw rod 20, the motor 21 and the second clamping plate 28, the motor 21 is started, and the motor 21 rotates to drive the bidirectional screw rod 20. Since the bidirectional screw rod 20 and the slider 18 are threadedly connected, the two sliders 18 can be driven to move relative to each other by the bidirectional screw rod 20. During the relative movement of the two sliders 18, the two second clamping plates 28 can be driven to move relative to each other, so that the objects can be positioned and clamped by the two second clamping plates 28, so that the positioning device can quickly position and clamp the objects during use.To ensure the accuracy and stability of the position of the object and avoid shaking of the object during processing to affect its processing quality, both ends of the second vertical plate 3 are fixedly connected with support frames 23, the inner walls of the two support frames 23 are connected to the outer wall of the same sliding rod 24, and the guide block 19 is slidably connected to the outer wall of the sliding rod 24. By setting the sliding rod 24 and the guide block 19, it can play a guiding and limiting role in the movement of the second clamping plate 28. The top of the bottom plate 1 is respectively connected to the bottom of the four cylinders 25, and the output ends of the four cylinders 25 are connected to the bottom of the same table panel 26. The bottom of the bottom plate 1 is connected to the top of the four supporting feet 27, and the four supporting feet 27 are distributed at the four corners of the bottom of the bottom plate 1. The bottom of the supporting feet 27 is provided with anti-slip pads. By providing the supporting feet 27, the positioning device can play a supporting role during use, thereby ensuring the stability of the supporting device.

[0024] The working principle of the utility model is:

[0025] When it is necessary to position the object, the object is first placed on the table panel 26, and then the cylinder 25 is started. The cylinder 25 drives the table panel 26 to rise, so that the table panel 26 and the second clamping plate 28 are at the same horizontal plane, and then the motor 21 is started. The motor 21 rotates and drives the bidirectional screw rod 20. Since the bidirectional screw rod 20 and the slider 18 are threadedly connected, the two sliders 18 can be driven to move relative to each other through the bidirectional screw rod 20. During the relative movement of the two sliders 18, the two second clamping plates 28 can be driven to move relative to each other, so that the object can be positioned and clamped through the two second clamping plates 28. When one end face of the object is processed, the motor 21 is reversed so that the second clamping plate 28 is moved relative to the second clamping plate 28. The second clamping plate 28 returns to the initial position, and then the second electric telescopic rod 10 is started, and the second electric telescopic rod 10 drives the first clamping plate 11. During the movement of the first clamping plate 11, the object can be moved, so as to cooperate with the first clamping plate 11 on the other side to fix the object, and then the cylinder 25 is closed to restore it to the initial position, and then the first electric telescopic rod 8 is started, and the first electric telescopic rod 8 drives the rack 6 to move. Since the rack 6 is meshed with the gear 5, the gear 5 can be driven to rotate through the rack 6, and the rotation of the gear 5 drives the rotating shaft 4 to rotate. The rotation of the rotating shaft 4 drives the first clamping plate 11 to rotate, and the object can be flipped during the rotation of the first clamping plate 11.
