DETAILED DESCRIPTION

[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] like Figure 1-3 As shown, the utility model provides a technical solution: a high-efficiency clamping device for mechanical processing, including a base plate 1, two fixed plates 2 are fixedly connected to the top of the base plate 1, and a limiting plate 25 is fixedly connected to the top of the two fixed plates 2. A first bearing 3 is fixedly connected to the fixed plate 2, and a bidirectional screw rod 4 is fixedly connected to the inner ring of the two first bearings 3. One end of the bidirectional screw rod 4 is connected to a first handle 5, and one end of the worm 14 is connected to a second handle 13. Due to the provision of the first handle 5, the first handle 5 makes the bidirectional screw rod 4 easier to be rotated, thereby improving the convenience of operation. Due to the provision of the first bearing 3, when the first handle 5 is rotated to drive the bidirectional screw rod 4 to rotate on the first bearing 3, the friction is smaller, and it is convenient to rotate the first handle 5.

[0021] Two movable plates 6 are threadedly connected to the bidirectional lead screw 4, and one end of the movable plate 6 is fixedly connected to the box body 7; a worm gear 16 is arranged inside the box body 7, and a worm 14 is meshed on the worm gear 16, and a second bearing 15 is sleeved on the worm 14. A waterproof box 18 is arranged on one side of the rotating cylinder 12. Because of the provision of the waterproof box 18, the waterproof box 18 can prevent moisture from entering the motor 19, thereby achieving the purpose of waterproofing the motor 19.

[0022] A rotating shaft 17 is fixedly connected to one side of the worm gear 16, and one end of the rotating shaft 17 away from the worm gear 16 passes through the box body 7 and is connected to the rotating cylinder 12. A motor 19 is fixedly connected to one side of the rotating cylinder 12, and a connecting rod 20 is connected to the output end of the motor 19. One end of the connecting rod 20 is fixedly connected to a driving bevel gear 21, and a driven bevel gear 22 is meshed on the driving bevel gear 21, and the driven bevel gear 22 is fixedly connected to the rotating rod 23.

[0023] Two third bearings 24 are fixedly connected to the rotating cylinder 12, and the inner rings of the two third bearings 24 are fixedly connected to a rotating rod 23, one end of the rotating rod 23 is connected to a curved splint 10, and the end of the rotating rod 23 away from the curved splint 10 is connected to a plane splint 11, a first plastic pad 8 is arranged on the plane splint 11, and a second plastic pad 9 is arranged on the curved splint 10. Because of the first plastic pad 8 and the second plastic pad 9, when the two plane splints 11 and the curved splint 10 clamp parts, the first plastic pad 8 and the second plastic pad 9 can prevent the plane splint 11 and the curved splint 10 from damaging the parts.

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

[0025] When it is necessary to clamp the curved surface part, the second handle 13 is rotated to drive the worm 14 and the worm wheel 16, and the rotating cylinder 12 and the rotating rod 23 are rotated through the rotating shaft 17, and the plane clamping plate 11 and the curved surface clamping plate 10 are rotated, so that the two curved surface clamping plates 10 are located between the two movable plates 6. At this time, the first handle 5 is rotated to drive the bidirectional screw 4 to rotate, so that the two movable plates 6, the box body 7 and the curved surface clamping plates 10 are close to each other, and the curved surface part is clamped. When it is necessary to clamp the flat part, the second handle 13 is rotated so that the two flat clamping plates 11 are located between the two movable plates 6.

[0026] When the clamped parts need to be turned over, the starting motor 19 drives the connecting rod 20, the active bevel gear 21, the driven bevel gear 22 and the rotating rod 23 to rotate, and the rotating rod 23 drives the arc surface clamping plate 10 to rotate, and drives the parts between the two arc surface clamping plates 10 to rotate and turn them over.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0028] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
