[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 mechanical parts processing positioning tool, including a connecting plate 1, four columns 2 are fixedly connected to the top of the connecting plate 1, a plastic gasket 3 is arranged at one end of the column 2, and two L-shaped rods 14 are slidably connected to the top of the connecting plate 1. Because the plastic gasket 3 is provided, when the first motor 7 drives the grinding plate 6 to grind the parts, the plastic gasket 3 is designed as plastic, which can reduce the wear of the ground caused by vibration during grinding.

[0021] A rack 13 is fixedly connected to the L-shaped rod 14, a second gear 17 is meshed on the rack 13, a rotating shaft 18 is fixedly connected to the second gear 17, a first gear 11 is fixedly connected to the rotating shaft 18, there are two first gears 11, a toothed plate 12 is meshed on the two first gears 11, a second screw rod 19 is threadedly connected to the toothed plate 12, one end of the second screw rod 19 is connected to the second motor 9, a fixed plate 10 is fixedly connected to the bottom of the second motor 9, a first motor 7 is fixedly connected to the bottom of the movable plate 8, and a grinding disc 6 is connected to the output end of the first motor 7.

[0022] A first screw rod 15 is threadedly connected to the L-shaped rod 14, one end of the first screw rod 15 is connected to the arc-shaped clamping plate 4, and the end of the first screw rod 15 away from the arc-shaped clamping plate 4 is connected to a nut 16. There are two nuts 16 in total, and the two nuts 16 are symmetrically arranged about the middle part of the connecting plate 1. Because a number of grooves are provided on the nut 16, the friction between the nut 16 and the human hand can be increased, which makes it easier to rotate the nut 16 and improves the convenience of operation. Because the arc-shaped clamping plate 4 is designed with an arc surface, it can better stick to a circular part, making it more stable when clamping the circular part.

[0023] There are two arc-shaped clamping plates 4, which are symmetrically arranged about the middle part of the connecting plate 1. A plastic sheet 5 is arranged on the arc-shaped clamping plates 4, and a movable plate 8 is fixedly connected to the tooth plate 12. Because of the plastic sheet 5, when the two arc-shaped clamping plates 4 clamp the parts, the plastic sheet 5 can protect the parts and prevent the arc-shaped clamping plates 4 from damaging the parts.

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

[0025] Place the part to be processed between the two arc-shaped clamping plates 4, start the second motor 9 to drive the second screw rod 19 to rotate, so that the tooth plate 12 moves downward, so that the two first gears 11 rotate, and through the rotating shaft 18, the two second gears 17 drive the rack 13, the L-shaped rod 14, the first screw rod 15 and the arc-shaped clamping plates 4 to approach each other to clamp the part. At this time, the grinding sheet 6 contacts the part, and the first motor 7 is started to drive the grinding sheet 6 to grind it. When the grinding is completed, start the second motor 9 to move the first motor 7 and the grinding sheet 6 upward, and make the two arc-shaped clamping plates 4 move away from each other to release the part. At this time, the staff can remove the processed parts, rotate the nut 16 to drive the first screw rod 15 and the arc-shaped clamping plates 4 to move, and then the distance between the two arc-shaped clamping plates 4 can be adjusted.

[0026] 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.

[0027] 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.
